                               PROSPECTUS SUMMARY

     The following summary contains basic information about RailWorks, the notes
and the exchange offer. It likely does not contain all the information that is
important to you. For a more complete understanding of the notes and the
exchange offer, we encourage you to read this entire document and the documents
to which we have referred you.


     As used in this prospectus, unless the context otherwise requires, "we,"
"us," "our," or "RailWorks" refers to the business of RailWorks Corporation and
its subsidiaries. The term "rail systems" means transit systems, regional and
shortline railroads, Class I railroads and commercial and on-site rail
infrastructure of industrial companies. Unless the context otherwise requires,
"pro forma" information gives effect to (1) the two acquisitions that we have
completed during 1998 and the 11 acquisitions that we have completed in the
first 10 months of 1999 as if we had completed these acquisitions on January 1,
1998 and (2) the sale of the old notes to the initial purchaser and the
application of the net proceeds from that sale.


                             RAILWORKS CORPORATION


     We are a leading provider of integrated rail system services and products
to a diverse base of customers throughout the United States. We believe we are
positioned to grow significantly due to our ability to comprehensively design,
supply, construct and maintain rail systems. Our strategy is based on providing
a full range of rail-related services and products on a "turnkey" basis
throughout North America and offering rail system solutions under the
"RailWorks" brand. We provide track construction, rehabilitation, repair and
maintenance; rail electrification and installation of communication and
signaling systems; and related products and supplies. We offer these services to
a wide variety of customers, including Class I and shortline railroads, publicly
funded transit authorities and commercial and industrial companies. We also
provide non-rail products and services such as electrical contracting, bridge
and highway support structures, and related concrete products. For the year
ended December 31, 1998, we had pro forma revenue of $544.8 million and pro
forma EBITDA of $60.6 million. For the nine months ended September 30, 1999, we
had pro forma revenue of $420.5 million and pro forma EBITDA of $52.9 million.


                                COMPANY HISTORY


     RailWorks Corporation was formed in March 1998 to become a leading
nationwide provider of rail system services, including construction and
rehabilitation, repair and maintenance, and related products. We currently have
29 operating companies that have been in the rail systems business for an
average of 27 years. We have acquired the operating companies through the
following transactions:


     - In August 1998, we acquired in separate concurrent transactions 14 groups
       of companies engaged principally in the rail system services and products
       business and we consummated our initial public offering (the "IPO"). We
       refer to these groups of companies as the "Founding Companies."

     - In November 1998, we acquired two companies.  We refer to these companies
       as the "1998 Acquired Companies."


     - In the first 10 months of 1999, we acquired 11 companies. We refer to
       these companies as the "1999 Acquired Companies." We refer to the 1998
       Acquired Companies and the 1999 Acquired Companies together as the
       "Acquired Companies." The Acquired Companies had combined fiscal 1998
       revenue of $275.3 million.

In addition, in December 1999, we acquired two additional companies engaged in
the rail products and services and transit services businesses. Based on
information provided by these two companies, they had combined revenue for 1998
of over $35 million.



                               THE EXCHANGE OFFER


The Exchange Offer.........  We are offering to exchange:

                             - $1,000 principal amount of our registered 11
                                1/2% senior subordinated notes due April 15,
                               2009, which we refer to as new notes,

                             for

                             - each $1,000 principal amount of our unregistered
                               11  1/2% senior subordinated notes due April 15,
                               2009, which we refer to as old notes

                             We sometimes will refer to the new notes and the
                             old notes together as the notes. Currently,
                             $50,000,000 aggregate principal amount of old notes
                             are outstanding. Under the indenture governing the
                             notes, we previously issued $125,000,000 aggregate
                             principal amount of 11 1/2% senior subordinated
                             notes due 2009, which we will refer to as the
                             existing notes.


Expiration date............  The exchange offer will expire at 5:00 p.m., New
                             York City time, on January 21, 2000, unless we
                             extend it. In that case the phrase "expiration
                             date" will mean the latest date and time to which
                             we extend the exchange offer. We will issue new
                             notes as soon as practicable after that date.


Conditions to the exchange
  offer....................  The exchange offer is subject to customary
                             conditions. We may assert or waive these conditions
                             in our sole discretion. If we materially change the
                             terms of the exchange offer, we will resolicit
                             tenders of the old notes. Please read the section
                             "The Exchange Offer -- Conditions of the Exchange
                             Offer" of this prospectus for more information
                             regarding conditions to the exchange offer.

Procedures for
participating in the
  exchange offer...........  If you wish to participate in the exchange offer,
                             you must complete, sign and date an original or
                             faxed letter of transmittal in accordance with the
                             instructions contained in the letter of transmittal
                             accompanying this prospectus. Then you must mail,
                             fax or deliver the completed letter of transmittal,
                             together with the old notes you wish to exchange
                             and any other required documentation to First Union
                             National Bank, which is acting as exchange agent.
                             Its address appears on the letter of transmittal.
                             By signing the letter of transmittal, you will
                             represent to and agree with RailWorks that

                             - you are acquiring the new notes in the ordinary
                               course of your business,

                             - you have no arrangement or understanding with
                               anyone to participate in a distribution of the
                               new notes, and

                                        2
<PAGE>   8

                             - you are not an "affiliate," as defined in Rule
                               405 under the Securities Act, of RailWorks.

                             If you are a broker-dealer that will receive new
                             notes for your own account in exchange for old
                             notes that you acquired as a result of your
                             market-making or other trading activities, you will
                             be required to acknowledge in the letter of
                             transmittal that you will deliver a prospectus in
                             connection with any resale of the new notes.

Resale of exchange notes...  We believe that you can resell and transfer your
                             new notes without registering them under the
                             Securities Act and delivering a prospectus, if you
                             can make the same three representations that appear
                             above under the heading "Procedures for
                             participating in the exchange offer." But, our
                             belief is based on interpretations of the SEC
                             expressed in some SEC no-action letters to other
                             issuers in exchange offers like ours.

                             We cannot guarantee that the SEC would make a
                             similar decision about this exchange offer. If our
                             belief is wrong, or if you cannot truthfully make
                             the representations mentioned above, and you
                             transfer any new note issued to you in the exchange
                             offer without meeting the registration and
                             prospectus delivery requirements of the Securities
                             Act, or without an exemption from such
                             requirements, you could incur liability under the
                             Securities Act. We are not indemnifying you for any
                             such liability.

                             A broker-dealer can only resell or transfer new
                             notes if it delivers a prospectus.

Special procedures for
  beneficial owners........  If your old notes are held through a broker,
                             dealer, commercial bank, trust company or other
                             nominee and you wish to surrender such old notes,
                             you should contact your intermediary promptly and
                             instruct it to surrender your old notes on your
                             behalf.

Guaranteed delivery
  procedures...............  If you cannot meet the expiration date deadline, or
                             you cannot deliver your old notes, the letter of
                             transmittal or any other documentation on time,
                             then you must surrender your old notes according to
                             the guaranteed delivery procedures appearing in
                             this prospectus under the heading "The Exchange
                             Offer -- Guaranteed Delivery Procedures."

Acceptance of your old
notes and delivery of the
  new notes................  We will accept for exchange any and all old notes
                             that are surrendered in the exchange offer prior to
                             the expiration date if you comply with the
                             procedures of the offer. The new notes will be
                             delivered as soon as practicable after the
                             expiration date.

Withdrawal rights..........  You may withdraw the surrender of your old notes at
                             any time prior to the expiration date.

                                        3

Certain federal income tax
  considerations...........  You will not have to pay federal income tax as a
                             result of your participation in the exchange offer.

Exchange agent.............  First Union National Bank is serving as the
                             exchange agent in connection with the exchange
                             offer. First Union National Bank also serves as
                             trustee under the indenture for the notes.

Failure to exchange old
notes will adversely affect
  you......................  If you are eligible to participate in this exchange
                             offer and you do not surrender your old notes as
                             described in this prospectus, you will not have any
                             further registration or exchange rights. In that
                             case your old notes will continue to be subject to
                             restrictions on transfer. As a result of such
                             restrictions and the availability of registered new
                             notes, the old notes are likely to be a much less
                             liquid security than before.

                             Neither the Delaware General Corporation Law nor
                             the indenture relating to the notes gives you any
                             appraisal or dissenters' rights or any other right
                             to seek monetary damages in court if you do not
                             participate in the exchange offer.

                                 THE NEW NOTES

     The new notes have the same financial terms and covenants as the old notes
and the existing notes, which are as follows:

Issuer.....................  RailWorks Corporation.

Securities offered.........  $50,000,000 principal amount of 11  1/2% senior
                             subordinated notes due 2009.

Maturity...................  April 15, 2009.

Interest rate..............  11 1/2% per year (calculated using a 360-day year).

Interest payment dates.....  April 15 and October 15, beginning on October 15,
                             1999. Interest began accruing on September 30, 1999
                             when we first issued the old notes.


Ranking....................  The new notes will be unsecured senior subordinated
                             obligations of RailWorks and they will rank junior
                             to our existing and future senior debt, including
                             our obligations under our credit facility. The
                             guarantees of the new notes by our subsidiaries
                             will be subordinated to existing and future senior
                             debt of such subsidiaries. On a pro forma basis, as
                             of September 30, 1999, pro forma for the
                             acquisition of the 1999 Acquired Companies,
                             borrowings under our new term loan facility, and
                             the sale of the old notes and the application of
                             the net proceeds, we would have had approximately
                             $50.4 million of senior debt, excluding
                             approximately $82.5 million that we expect to have
                             available to borrow under our credit facility.


Guarantees.................  Our domestic subsidiaries will unconditionally
                             guarantee the new notes. If we create or acquire a
                             new domestic subsidiary, it will guarantee the
                             notes unless we designate the subsidiary as an
                             "unrestricted subsidiary" under the indenture or
                             the subsidiary does not have significant assets.
                                        4

Optional redemption........  We cannot redeem the new notes until April 15,
                             2004. After April 15, 2004, we may elect to redeem
                             some or all of the notes and the existing notes at
                             the redemption prices listed under the heading
                             "Description of the Exchange Notes" section under
                             the heading "Optional Redemption," plus accrued and
                             unpaid interest.

Optional redemption after
  equity offerings.........  At any time, which may be more than once, before
                             April 15, 2002, we may elect to redeem up to 35% of
                             the outstanding notes and the existing notes with
                             funds that we raise in one or more equity offerings
                             as long as:

                             - we pay 111.500% of the face amount of the notes,
                               plus interest;

                             - we redeem the notes and the existing notes within
                               120 days of completing the equity offering;

                             - at least 65% of the aggregate principal amount of
                               notes and the existing notes issued remains
                               outstanding.

Change of control offer....  If a change in control of RailWorks occurs, we must
                             give holders of the new notes and the existing
                             notes the opportunity to sell their new notes to
                             us, at 101% of their face amount, plus accrued and
                             unpaid interest.

                             We might be unable to pay you the required price
                             for any new notes and the existing notes you
                             present to us at the time of a change of control,
                             because:

                             - we might not have enough cash at that time; or

                             - the terms of our senior debt may prevent us from
                               paying.

Asset sale proceeds........  If we or our subsidiaries engage in asset sales, we
                             cannot freely use the proceeds of those sales.
                             Generally, we must either invest the net cash
                             proceeds from such sales in our business within a
                             specified period of time, prepay senior debt or
                             make an offer to purchase a principal amount of the
                             notes and existing notes equal to the excess net
                             cash proceeds. The purchase price for the notes and
                             the existing notes would be 100% of their principal
                             amount, plus accrued and unpaid interest.

Certain additional
indenture provisions.......  The indenture governing the notes is the same
                             indenture that governs the existing notes. It
                             contains covenants limiting our (and most or all of
                             our subsidiaries') ability to:

                             - incur additional debt or enter into sale and
                               leaseback transactions;

                             - pay dividends or distributions on our capital
                               stock or repurchase our capital stock;

                             - issue stock of subsidiaries;

                             - make certain investments;

                             - create liens on our assets to secure debt;

                                        5
<PAGE>   11

                             - enter into transactions with affiliates;

                             - merge or consolidate with another company; and

                             - transfer and sell assets.

                             These covenants are subject to a number of
                             important limitations and exceptions.

Use of proceeds............  We will not receive any proceeds from the exchange
                             offer. See "Use of Proceeds." We have agreed to
                             bear the expenses of the exchange offer. No
                             underwriter has been retained to carry out the
                             exchange offer.

     For additional information regarding the new notes, see "Description of the
New Notes."

     SUMMARY HISTORICAL AND UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA

     RailWorks acquired the Founding Companies concurrently with the
consummation of the IPO on August 4, 1998. For accounting and financial
statement purposes, Comstock Holdings, Inc. (one of the Founding Companies) was
identified as the "accounting acquirer" consistent with the requirements of

been accounted for as purchases in accordance with Accounting Principles Board
("APB") No. 16.

     The summary unaudited pro forma consolidated financial data presented below
are derived from unaudited pro forma consolidated financial data contained

 (1) The summary historical consolidated financial data as of and for the fiscal
     year ended December 31, 1998 are derived from our Consolidated Financial
     Statements, which are comprised of financial data of:
     - Comstock Holdings, Inc., the accounting acquirer, for the year ended
       December 31, 1998;
     - the Founding Companies, other than Comstock Holdings, Inc., for the
       period from August 1, 1998 through December 31, 1998; and
     - the 1998 Acquired Companies for the period from November 4, 1998 through
       December 31, 1998.
 (2) Reflects the acquisitions of the Founding Companies and the Acquired
     Companies as if they each had occurred on January 1, 1998.
 (3) Reflects the acquisitions of the Founding Companies and the Acquired
     Companies as adjusted to give effect to the sale of the old notes and the
     application of the net proceeds as if they each had occurred on January 1,
     1998.

 (4) The summary historical consolidated financial data as of and for the nine
     months ended September 30, 1999 are derived from our unaudited Consolidated
     Financial Statements contained elsewhere in this prospectus. In our
     opinion, such unaudited statements include all adjustments (consisting of
     only normal recurring accruals) necessary for a fair presentation of our
     financial position and results of operations for such period. Our results
     of operations for the nine months ended September 30, 1999 are not
     necessarily indicative of the results that may be expected for the full
     year.

 (5) Reflects the acquisitions of the 1999 Acquired Companies as if they each
     had occurred on January 1, 1999.

     give effect to the sale of the old notes and the application of the net
     proceeds as if they each had occurred on January 1, 1999.
 (7) Consists of $14.5 million in restricted common stock granted to the
     Company's officers, $2.9 million related to settlement of employee benefit
     obligations of one of the operating companies and corporate relocation
     costs, $2.2 million in estimated legal and settlement costs in connection
     with former operations of one of the operating companies and $400,000 in
     transfers of common stock made by certain operating company managers to
     other employees of such operating companies.
 (8) Represents offering expenses incurred in connection with the initial public
     offering of common stock of RailWorks.

 (9) EBITDA is the sum of earnings before interest, income taxes, depreciation
     and amortization expense. Included in EBITDA is income earned on contract
     retainages pursuant to contractual agreements with certain customers.
     EBITDA is presented because we believe that it is a widely accepted
     financial indicator of a company's ability to service indebtedness.
     However, EBITDA does not represent net income or cash flow from operations
     as defined by generally accepted accounting principles, is not necessarily
     indicative of cash available to fund all cash flow needs, should not be
     considered as an alternative to net income or to cash flows from operating
     activities (as determined in accordance with generally accepted accounting
     principles) and should not be construed as an indication of a company's

                                        8
<PAGE>   14
     operating performance or as a measure of liquidity. EBITDA is not
     necessarily comparable with similarly titled measures presented by other
     companies.
(10) Represents EBITDA as a percentage of revenue.
(11) The ratio of earnings to fixed charges is calculated by dividing the fixed
     charges into net income before taxes and minority interests plus fixed
     charges. Fixed charges consist of interest expense, amortization of
     deferred debt issuance costs and the estimated interest component of rent
     expense.

     September 30, 1999.

     The pro forma financial data set forth below reflect the results of
operations of the Founding Companies as if we had acquired them on January 1,
1997. The presentation only includes the results of the 1998 Acquired Companies
from November 4, 1998 to December 31, 1998. Acquired Companies are otherwise

                                  RISK FACTORS

     You should carefully consider the information below as well as to all other
information provided to you in this prospectus before deciding whether to tender
your old notes in exchange for new notes pursuant to the exchange offer. These
risks apply to both the old notes and the new notes.

RISKS RELATING TO THE NEW NOTES

     There Could Be Adverse Consequences of Failure to Exchange Your Old Notes
for New Notes. The old notes were not registered under the Securities Act or
under the securities laws of any state and may not be resold, offered for resale
or otherwise transferred unless they are subsequently registered or resold
pursuant to an exemption from the registration requirements of the Securities
Act and applicable state securities laws. If you do not exchange your old notes
for new notes pursuant to the exchange offer, you will not be able to resell,
offer to resell or otherwise transfer the old notes unless they are registered
under the Securities Act or unless you resell them, offer to resell or otherwise
transfer them under an exemption from the registration requirements of, or in a
transaction not subject to, the Securities Act. In addition, we will no longer
be under an obligation to register the old notes under the Securities Act except
in the limited circumstances provided under the registration rights agreement.
In addition, to the extent that old notes are tendered for exchange and accepted
in the exchange offer, the trading market for the untendered and tendered but
unaccepted old notes could be adversely affected. Please refer to the section
captioned "Risk Factors -- No Assurance of Active Trading Market for the Notes."


     We Have Substantial Leverage. Our substantial indebtedness could adversely
affect our financial health and could prevent us from fulfilling our obligations
under the notes. We have a substantial amount of debt outstanding. On a pro
forma basis, as of September 30, 1999, we would have had outstanding total debt
of $272.2 million (excluding approximately $82.5 million that we expect to have
available to borrow under our credit facility), ratio of earnings to fixed
charges of 1.8 and stockholders' equity of $129.3 million. In November 1999 we
entered into a $30 million term loan facility. As of December 6, 1999, this
facility was fully drawn and we had $30.0 million of borrowings outstanding
under this facility, which is included in our total pro forma debt above.



     We May Make Additional Borrowings.  Despite current indebtedness levels, we
and our subsidiaries will also be permitted to incur substantial additional debt
in the future. On a pro forma basis as of September 30, 1999, $82.5 million
would have been available for additional borrowing under our credit facility
(subject to customary borrowing conditions). If new debt is added to our and our
subsidiaries' current debt levels, the related risks that we and they now face
could intensify. Please refer to the sections of this prospectus entitled
"Capitalization", "Selected Historical Consolidated Financial Data", and
"Description of the Notes -- Certain Covenants -- Limitation on Incurrence of
Additional Indebtedness".


     Our substantial amount of debt could have important consequences for you.
For example, it could:

     - make it more difficult for us to satisfy our obligations with respect to
       the notes;

     - limit our ability to obtain additional financing, if we need it, for
       working capital, capital expenditures, acquisitions, debt service
       requirements or other purposes;

     - increase our vulnerability to adverse economic and industry conditions;

     - require us to dedicate a substantial portion of our cash flow from
       operations to payments on our debt, thereby reducing funds available for
       operations, future business opportunities or other purposes;

                                       10
<PAGE>   16

     - limit our flexibility in planning for, or reacting to, changes in our
       business and the industry in which we compete; and

     - place us at a competitive disadvantage compared to our competitors that
       have less debt.

     We May be Unable to Service Debt.  To service our indebtedness, we will
require a significant amount of cash. Our ability to make payments on our debt,
including the notes and the existing notes, and to fund planned capital
expenditures and acquisitions will depend on our future operating performance
and on our ability to successfully implement our business strategy. Prevailing
general economic conditions and financial, business, regulatory and other
factors, many of which are beyond our control, will affect our ability to make
these payments. Based on our current level of operations, we believe that our
cash flow from operations, available cash and available borrowings under our
credit facility will be adequate to meet our liquidity needs for the foreseeable
future.


     We cannot assure you, however, that we will realize anticipated financial
results or be successful in implementing our business strategy. If future cash
flow is not sufficient to make scheduled payments on our debt, including the
notes and the existing notes, we will need to refinance all or a portion of our
debt, including the notes and the existing notes, before maturity, obtain
additional financing, delay planned acquisitions and capital expenditures, or
sell assets. We cannot assure you that we will be able to refinance any of our
debt, including debt outstanding under our credit facility, term loan facility
and the notes, on commercially reasonable terms. We also cannot assure you that
we would be able to make an asset sale on a timely basis for proceeds sufficient
to cover our debt service requirements. The terms of our credit facility, term
loan facility and the indenture governing the notes and the existing notes
restrict our ability to sell assets.


     If for any reason we are unable to meet our debt service obligations, we
would be in default under the terms of our credit facility. If such a default
were to occur, the lenders under our credit facility could elect to declare all
of our debt under the facility immediately due and payable, including accrued
and unpaid interest, and the lenders would not be obligated to continue to
advance funds under the facility. If the amounts outstanding under the credit
facility are accelerated, we cannot assure you that our assets will be
sufficient to repay in full the money owed to the banks or to our other debt
holders.


     The Notes Rank Behind Other Indebtedness.  The notes and the guarantees
rank behind all of our and the guarantors' existing and future senior debt,
including debt under our credit facility and term loan facility and rank equally
in right of payment with the existing notes. On a pro forma basis, as of
September 30, 1999, we and the guarantors would have had $50.4 million of senior
debt outstanding. This amount does not include the $82.5 million that we expect
to have available to borrow under our credit facility, all of which would be
senior debt. In the event of our or any of the guarantors' bankruptcy,
liquidation or reorganization, our and the guarantors' assets will be available
to pay our obligations on the notes only after we have repaid all of our and the
guarantors' senior debt in full. We cannot assure you that sufficient assets
will remain to make full payment on the notes after such payments are made.


     In the event of bankruptcy, liquidation or reorganization or any similar
proceeding relating to the Company or the guarantors, holders of the notes and
the existing notes will participate with trade creditors and all other holders
of our and the guarantors' subordinated indebtedness in the assets remaining
after we and such guarantors have repaid in full all of our senior debt. In
addition, the subordination provisions of the indenture provide that we cannot
make cash payments on the notes and the existing notes while a payment default
is continuing under certain of our senior debt.


     Our Credit Facilities and the Indenture Impose Certain Restrictions. Our
credit facility, term loan facility and the indenture governing the notes and
the existing notes contain a number of significant covenants that, among other
things, restrict our ability to dispose of assets, incur


                                       11
<PAGE>   17

additional indebtedness, repay other indebtedness, pay dividends, make certain
investments or acquisitions, repurchase or redeem capital stock, engage in
mergers or consolidations, or engage in certain transactions with subsidiaries
and affiliates and otherwise restrict corporate activities. We cannot assure you
that such restrictions will not adversely affect our ability to finance future
operations or capital needs or engage in other business activities that may be
in our best interest.


     In addition, our credit facility and term loan facility require us to
maintain compliance with financial ratios. Our ability to comply with these
ratios may be affected by events beyond our control. We have granted the lenders
under the credit facility and term loan facility a first lien on all of the
capital stock of our subsidiaries and on all accounts receivable of us and our
subsidiaries. In the event of a default under the credit facility or term loan
facility, the lenders under such facility could foreclose upon the assets
pledged to them and the holders of the notes might not be able to receive any
payments until any payment default was cured or waived, any acceleration was
rescinded, or the indebtedness outstanding under our credit facility and/or term
loan facility was repaid. See "Description of Credit Facility" and "Description
of Term Loan Facility".



     A breach of any of the covenants contained in our credit facility or term
loan facility or our inability to comply with the required financial ratios
could result in an event of default, which would allow the lenders under such
facility to declare all borrowings outstanding to be due and payable. In
addition, our lenders could compel us to apply all of our available cash to
repay our borrowings or they could prevent us from making debt service payments
on the notes and the existing notes. If the amounts outstanding under the credit
facility, the term loan facility or the notes were to be accelerated, we cannot
assure you that our assets would be sufficient to repay in full the money owed
to the banks or to our other debt holders, including you as a noteholder.


     Fraudulent Conveyance Laws Permit Courts to Void Notes in Specific
Circumstances. Federal and state statutes allow courts, under specific
circumstances, to void the notes and the guarantees and require noteholders to
return payments received from RailWorks or the guarantors in the event of the
bankruptcy or other financial difficulty of RailWorks or any of the guarantors.
Under the federal bankruptcy law and comparable provisions of state fraudulent
transfer laws, a guarantee of the notes could be voided, or claims in respect of
a guarantee could be subordinated to all other indebtedness of any subsidiary
that is the guarantor if, among other things, at the time the guarantor incurred
the debt evidenced by its guarantee, the guarantor:

     - received less than reasonably equivalent value or fair consideration for
       the incurrence of such guarantee;

     - was insolvent or was rendered insolvent by reason of such incurrence;

     - was engaged in a business or transaction for which the guarantor's
       remaining assets constituted unreasonably small capital; or

     - intended to incur, or believed (or reasonably should have believed) that
       it would incur, debts beyond its ability to pay such debts as they
       mature.

     In addition, any payment by that guarantor pursuant to its guarantee could
be voided and required to be returned to the guarantor, or to a fund for the
benefit of the creditors of the guarantor.

     The measure of insolvency for purposes of these fraudulent transfer laws
will vary depending upon the law applied in any proceeding to determine whether
a fraudulent transfer has occurred. Generally, however, a guarantor of the notes
would be considered insolvent if:

     - the sum of its debts, including contingent liabilities, were greater than
       the fair saleable value of all of its assets;

                                       12
<PAGE>   18

     - if the present fair saleable value of its assets were less than the
       amount that would be required to pay its probable liability on its
       existing debts, including contingent liabilities, as they become absolute
       and matured; or

     - it could not pay its debts as they become due.

     A court is likely to find that a guarantor of the notes did not receive
fair consideration or reasonably equivalent value for its guarantee to the
extent that its liability under the guarantee is greater than the direct benefit
it received from the issuance of notes. By its terms, each guarantee of the
notes will limit the liability of the guarantor to the maximum amount that it
can pay without the guarantee being deemed a fraudulent transfer. A court may
not give effect to this limitation on liability. In that event, a court may find
that the issuance of the guarantee rendered the subsidiary guarantor insolvent.
If a court voids the guarantee or holds it unenforceable, you will cease to have
a claim against the subsidiary guarantor and will be a creditor solely of
RailWorks. If the limitation on liability is effective, the amount that the
guarantor is found to have guaranteed might be so low that there will not be
sufficient funds to pay the notes in full.


     On the basis of historical financial information, recent operating results
and other factors, RailWorks and each guarantor believes that, after giving
effect to the indebtedness incurred in connection with the sale of the old notes
and the credit facility, it will not be insolvent, will not have unreasonably
small capital for the business in which it operates and will not have incurred
debts beyond its ability to pay such debts as they mature. We cannot assure you,
however, as to what standard a court would apply in making such determinations
or that a court would agree with our or the guarantors' conclusions in this
regard.



     We May be Unable to Finance a Change of Control Offer.  Upon the occurrence
of specific kinds of change of control events, we must offer to repurchase all
outstanding notes and all existing notes. However, it is possible that we will
not have sufficient funds at the time of the change of control to make the
required repurchase of notes and existing notes or that restrictions in our
credit facilities will not allow such repurchases. In addition, certain
important corporate events, such as leveraged recapitalizations that would
increase the level of our indebtedness, would not constitute a "Change of
Control" under the indenture and in such a circumstance, we would not have to
make an offer to repurchase the notes and the existing notes. See "Description
of the Notes -- Redemption."


     There is No Public Market for the New Notes.  The new notes are new
securities for which there is currently no trading market. We do not intend to
list the new notes on any securities exchange. Although we expect the new notes
to be eligible for trading in the PORTAL market, we cannot assure you that an
active trading market for the new notes will develop.

     The liquidity of any market for the notes will depend upon various factors,
including:

     - the number of holders of the notes;

     - the interest of securities dealers in making a market for the notes;

     - the overall market for high-yield securities;

     - our financial performance and prospects; and

     - the prospects for companies in our industry generally.

     Historically, the market for non-investment grade debt has been subject to
disruptions that have caused substantial volatility in the prices of securities
similar to the new notes. We cannot assure you that the market for the new
notes, if any, will not be subject to similar disruptions. Any such disruptions
may adversely affect you as a holder of the new notes.

     In addition, to the extent that old notes are surrendered and accepted in
the exchange offer, the trading market for unsurrendered old notes and for
surrendered-but-unaccepted old notes

                                       13
<PAGE>   19

could be adversely affected due to the limited amount of old notes that are
expected to remain outstanding following the exchange offer. Generally, when
there are fewer outstanding securities of a given issue, there is less demand to
purchase such security, which results in a lower price for such security.
Conversely, if many old notes are not surrendered, or are surrendered-but-
unaccepted, the trading market for the new notes could be adversely affected.
See "Plan of Distribution" and "The Exchange Offer" for further information
regarding the distribution of the new notes and the consequences of failure to
participate in the exchange offer.

RISKS RELATING TO RAILWORKS


     The Operating Companies Do Not Have a Combined Operating History; We May be
Unsuccessful Integrating Their Decentralized Operations.  RailWorks was founded
in March 1998 but conducted no operations and generated no revenue until we
completed our initial public offering, or "IPO", of our common stock in August
1998. We acquired the Founding Companies concurrently with the completion of our
IPO, have acquired 15 additional operating companies since that time, and have
entered into letters of intent to acquire four additional operating companies.
Our operating companies were separate independent entities before we acquired
them and to a certain extent they continue to operate as independent entities
because we conduct our operations on a decentralized basis. The integration of
our operating companies, while allowing them to retain decentralized operations
and management, is important to our operating and growth strategies and the
achievement of efficiencies in the combined operation. We may not be able to
integrate the operations or the necessary systems and procedures, including
accounting and financial reporting systems and project management systems, to
manage effectively the combined enterprise. Some members of our management group
have only recently joined RailWorks and we cannot guarantee that the management
group will successfully implement our acquisition and operating strategies. We
cannot assure you that we will be able to establish, maintain or increase the
profitability of the operating companies. Our pro forma financial statements
include results of operations for certain operating companies when they were not
under common control or management. As a result, our pro forma financial
statements may not be indicative of our future results of operations. Any
failure by our management group to implement our strategies, integrate the
operating companies without substantial costs, delays or other operational or
financial difficulties, or oversee effectively the combined entity could have a
material adverse effect on our business, financial condition and results of
operations.



     We May be Unable to Complete and Finance Acquisitions.  We have completed
15 acquisitions since the IPO and we intend to grow significantly through the
acquisition of additional businesses. See "Business -- Strategy." Our
acquisition strategy entails reviewing acquired business operations, corporate
infrastructure and systems and financial controls. Unforeseen expenses,
difficulties, complications and delays frequently encountered in connection with
the rapid expansion of operations could inhibit our growth or adversely affect
our financial performance.



     We have also signed letters of intent to purchase four operating companies.
We expect to execute definitive purchase agreements with one exception, which
will have customary closing conditions (including completion of due diligence),
prior to the end of 1999. However, there can be no assurance that we will
acquire any of these companies.


     We cannot assure you that we will maintain or accelerate our growth or
anticipate all of the changing demands that expanding operations will impose on
our management, personnel, operational and management information systems and
financial systems. We may not be able to identify, acquire or manage profitably
additional businesses or to integrate successfully any acquired businesses
without substantial costs, delays or other operational or financial
difficulties. Any such occurrence could have a material adverse effect on our
business, financial condition and results of operations.

                                       14
<PAGE>   20


     We cannot predict the timing, size and success of our acquisition efforts
and any associated capital commitments. We currently intend to finance future
acquisitions with bank borrowings, shares of our common stock, internally
generated funds or a combination of common stock and cash. If our common stock
does not maintain a sufficient market value, or if potential acquisition
candidates are otherwise unwilling to accept common stock as part of the
consideration for the sale of their businesses, we may be required to utilize
more of our cash resources or borrowings to maintain our acquisition program. In
addition, our acquisitions typically provide for the sellers to receive
contingent consideration, which is only paid if the acquired companies achieve
certain operating results. These payments could be substantial. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operation -- Liquidity and Capital Resources".


     We May be Unable to Generate Internal Growth.  Our ability to grow will be
affected by various factors, including demand for rail system services and
products, our success in bidding on new projects, the success of our
cross-selling efforts and our ability to develop a national accounts program.
Our growth may also depend on increased outsourcing by rail system operators.
Many of these factors are beyond our control. Our strategies may not be
successful or we may be unable to generate cash flow adequate for combined
operations and to support internal growth. The senior managers of the operating
companies retain responsibility for day-to-day operations. If proper business
controls are not implemented and maintained, this decentralized operating
strategy could result in inconsistent operating and financial practices of the
operating companies, which could have a material adverse effect on our business,
financial condition and results of operations. See "Business -- Strategy".


     We Have Been Dependent on Certain Customers.  We derived approximately
28.1% of our pro forma revenue for the year ended December 31, 1998 from our top
ten customers. Approximately 15.4% of our 1998 pro forma revenue was derived
from projects undertaken for the New York City Transit Authority ("NYCTA").
These projects were undertaken under a number of separate contracts. If the
NYCTA were to significantly reduce the amount of business that it does with us
or determine not to do business with us in the future, it would have a material
adverse effect on our business, financial condition and results of operations.
See "Business -- Customers".


     Certain Operating Companies Have a History of Losses.  From time to time,
primarily due to industry cyclicality and uncertainties inherent in the
competitive bidding process, certain of our operating companies have experienced
net losses. See "-- Our Fixed Price Contracts Expose us to Significant Risks"
below. We cannot assure you that we or our operating companies will be
profitable in the future. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations".

     We May Face Intense Competition.  The rail system services and products
industry is highly competitive. Numerous companies provide services to transit
authorities, construct and repair rail systems or sell related products or
supplies, and some of these companies operate in more than one of these lines of
business. Some of our competitors have greater resources than we have, may also
provide a broad range of services and products and may have sufficient bonding
capacity and other resources to undertake large projects. Any inability to
compete successfully against our existing and future competitors would have a
material adverse effect on our business, financial condition and results of
operations. Certain of our operating companies also provide electrical
contracting services to non-rail industrial and commercial customers. While we
believe that we currently compete effectively in the non-rail electrical
contracting business, this industry is highly competitive and is served by
small, owner-operated private companies, public companies and several large
regional companies. Additionally, we could face competition in the future from
other competitors entering our markets. See "Business -- Competition".

     We are Dependent on Public Sector Contracts and Funding.  The rail system
services and products business involves contracts that are supported by funding
from federal, state and local

                                       15
<PAGE>   21

governmental agencies, as well as contracts with such agencies ("public sector
contracts"). Public sector contracts are subject to detailed regulatory
requirements and public policies, as well as funding priorities. These contracts
may be conditioned upon the continuing availability of public funds, which in
turn depends upon lengthy and complex budgetary procedures. These contracts may
also be subject to significant pricing constraints. Moreover, public sector
contracts may generally be terminated for reasons beyond the control of the
contractor, including when such termination is in the best interests of the
governmental agency. We cannot assure you that these factors or others unique to
public sector contracts will not have a material adverse effect on our business,
financial condition and results of operations. See "Business -- Government
Regulation".

     Our Fixed Price Contracts Expose us to Significant Risks.  Fixed price
contracts are typically awarded in the rail system services industry pursuant to
a competitive bidding process. In compiling our bid on a particular project, we
must estimate the time it will take to complete the project, along with the
project's labor and supply costs. These costs may be affected by a variety of
factors, some of which may be beyond our control. If we cannot accurately
predict the costs of fixed price contracts, certain projects could have lower
margins than anticipated or we could suffer losses on the projects. Lower
margins and losses could have a material adverse effect on our business,
financial condition and results of operations.

     We Rely on Subcontractors and Suppliers.  We generally perform electrical
contracting services for transit signaling and communication systems as a
subcontractor to companies that design the systems and manufacture or purchase
the necessary equipment. In other instances, we act as the prime contractor and
subcontract the design of the signal or communication system and necessary
equipment. When we are a prime contractor for such projects, we generally
require subcontractors to post performance bonds. We may not require a
subcontractor to post a performance bond in situations where (1) the
subcontractor has strong experience with a specific type of project and
demonstrates financial stability and (2) the customer does not require bonds
from us as prime contractor. We sometimes depend upon the subcontractor to
perform design and other services and provide equipment. For certain projects
there are a limited number of companies that can perform the subcontract if the
initial subcontractor defaults. As a result, we depend upon our subcontractors
to perform under the subcontracts. Further, the major components of signaling
and communication systems for transit authorities are manufactured to
specifications and require long lead times for production. If a subcontractor or
supplier defaults, or if a supplier refuses or cannot do business with us, it
could have a material adverse effect on our business, financial condition and
results of operations.

     The Rail System Industry is Cyclical.  A substantial portion of our revenue
is derived from public contracts, which we expect to constitute a relatively
stable source of business due to funding provided by TEA 21. However, demand for
rail system services and products could fluctuate in conjunction with overall
economic conditions. In economic downturns, rail system operators may defer
certain construction and rehabilitation projects and purchases of related
products to conserve cash in the short term. Reductions in freight traffic due
to economic downturns or other factors may also reduce demand for our
construction and rehabilitation services and related products. In economic
upturns, railroads, particularly Class I railroads, experience heavier traffic
demands that can cause problems associated with congestion. The operational
problems related to congestion have an unpredictable impact on railroad
expenditures for construction and rehabilitation services and related products,
including those we provide. During periods of peak usage, rail system owners may
defer certain expenditures because they may need to address operational
challenges these conditions cause. Other issues, such as the possibility of
heightened government regulation during periods of congestion and the internal
challenges of managing railroad operations as the Class I railroads continue to
consolidate, may exacerbate the effects of these uncertainties.

                                       16
<PAGE>   22


     We are Exposed to Downturns in Commercial Construction.  We derived
approximately 10.4% of our pro forma revenue for the year ended December 31,
1998 from installation of electrical systems in newly constructed or renovated
commercial buildings and power and industrial plants. Fluctuations in the level
of new construction and renovation of commercial buildings affect the demand for
electrical installation services. These fluctuations reflect the cyclical nature
of the construction industry and depend upon general economic conditions,
changes in interest rates and other related factors. Downturns in levels of
commercial construction and renovation could have a material adverse effect on
our business, financial condition and results of operations. Further, our
electrical installation business is focused in the northeastern United States
and is therefore particularly susceptible to economic downturns in that region.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations".



     Our Workforce is Unionized.  As of September 30, 1999, approximately 50.0%
of our employees were covered under collective bargaining agreements. In June
1994, one of our operating companies was affected by a one-week work stoppage by
the United Brotherhood of Teamsters. We cannot assure you that future work
stoppages will not affect us. In addition, labor agreements are generally
negotiated on an industry-wide basis and the terms and conditions of future
labor agreements could be beyond our control. We may be subject to terms and
conditions in future labor agreements that could have a material adverse effect
on our business, financial condition and results of operations. See
"Business -- Employees".


     We are Subject to Extensive Environmental and Government Regulation.  Our
operations are subject to extensive federal, state and local regulation under
environmental laws and regulations. Among other things, these laws and
regulations cover emissions to the air, discharges to waters and the generation,
handling, storage, transportation, treatment and disposal of waste, underground
and aboveground storage tanks and remediation of soil and groundwater
contamination. Environmental liability can extend to previously owned or
operated properties, leased properties and properties owned by third parties, as
well as to properties currently owned and used by us. Environmental liabilities
may also arise from claims asserted by adjacent landowners or other third
parties in toxic tort litigation. We could incur significant ongoing costs
associated with environmental regulatory compliance. Further, we sometimes use
hazardous materials in connection with our operations. Although we believe that
we are in material compliance with all of the various environmental regulations
applicable to our business, we cannot assure you that requirements will not
change in the future or that we will not incur significant costs to comply with
such requirements.

     In addition to safety, health and other regulations of general
applicability, our operations may be significantly affected by regulations of
the Surface Transportation Board, the Federal Railroad Administration, the
Occupational Safety and Health Administration, state departments of
transportation and other state and local regulatory agencies. Changes in
regulation of the rail and transit industries through legislative,
administrative, judicial or other action could have a material adverse effect on
our business, financial condition and results of operations. See "Business --
Government Regulation."


     We are Dependent on Key Personnel.  Our success depends to a significant
extent upon the efforts and abilities of John G. Larkin, Chairman of the Board
and Chief Executive Officer, and Michael R. Azarela, Executive Vice President
and Chief Financial Officer. We also rely on senior management of our operating
companies. While we have entered into employment agreements with Messrs. Larkin
and Azarela and certain senior managers of the operating companies, we cannot be
certain that such individuals will remain with us throughout the terms of their
agreements, or thereafter. Further, it is likely we will depend on the senior
management of any significant businesses we acquire in the future. The loss of
the services of one or more of these key employees before we are able to attract
and retain qualified replacement personnel could


                                       17
<PAGE>   23

have a material adverse effect on our business, financial condition and results
of operation. See "Management."


     Our Systems May Not be Year 2000 Compliant.  We have developed a plan to
address year 2000 issues. To date, we have substantially completed the
identification, assessment, remediation, and testing of our internal information
systems and other equipment with date-sensitive operating controls, such as
manufacturing equipment, HVAC, security and other similar systems.



     We have also been in communication with hardware and software vendors with
whom we transact business, third parties with whom we exchange information
electronically, major or sole source suppliers, government agencies, and major
customers. The focus of these communications is to determine the state of
readiness of each of these third parties with respect to their own year 2000
issues and how their progress may impact us. The majority of responses received
from third party inquiries indicate that they are working on their year 2000
issues, but the responses do not provide specific details. Follow-up action
related to material third party inquiries and responses is expected to continue
as these material third parties progress in their own year 2000 readiness
projects. We have no means of ensuring that third parties with whom we deal will
be year 2000 compliant or that the information obtained from such third parties
regarding year 2000 compliance will prove to be accurate.



     While we anticipate that all computer systems have been assessed, remedied
and tested, there can be no assurance that all will be completely error free and
that such programs will be compliant by such dates. We rely on third party
software, equipment and services to conduct our business. While we believe we
have made reasonable efforts to address this issue, we have no means of ensuring
that third parties with whom we deal will be year 2000 compliant or that the
information obtained from such third parties regarding year 2000 compliance will
prove to be accurate.



     We believe that it is difficult to specifically identify the most
reasonably likely worst case year 2000 scenario. The following factors could
result in interruptions to our operations or business activities:



     - the failure to correct a material year 2000 problem,



     - the inability of any key customer, key supplier or governmental agency to
       make the necessary computer system changes on a timely basis,



     - the inaccuracy of responses received from these third parties, and



     - the potential shortage of skilled human resources to install and test
       upgraded software and equipment.



     Due to the general uncertainty inherent in the year 2000 issues,
particularly as it relates to the readiness of our key customers and suppliers,
and of governmental agencies, we cannot ascertain at this time whether the
consequences of year 2000 failures will have a material impact on our results of
operations, liquidity or financial condition. Our insurance coverage is limited
to business interruptions resulting from fire, explosion, or related perils
which are caused by a year 2000 system failure.



     Our year 2000 efforts are ongoing and our consideration of contingency
plans will continue to evolve as new information becomes available. While we
anticipate continuity of our business activities, that continuity will depend
upon our ability, and the ability of third parties upon whom we rely on directly
or indirectly, to be year 2000 compliant. You are cautioned that you should read
forward-looking statements regarding Year 2000 issues in conjunction with
"Disclosure Regarding Forward-Looking Statements".

                         PRO FORMA FINANCIAL STATEMENTS


     The following unaudited pro forma financial statements for the year ended
December 31, 1998 give effect to (1) the acquisitions by RailWorks of the
Founding Companies and the Acquired Companies as if each had occurred on January
1, 1998 and (2) the sale of the old notes and the application of the net
proceeds. The unaudited pro forma financial statements for the nine months ended
September 30, 1999 give effect to (1) the acquisitions of the 1999 Acquired
Companies as if each had occurred on January 1, 1999 and (2) the sale of the old
notes and the application of the net proceeds. The unaudited pro forma balance
sheet gives effect to the acquisition of the 1999 Acquired Companies and the
sale of the old notes and the application of the net proceeds as if each had
occurred on September 30, 1999.



     The unaudited pro forma statement of operations for the year ended December
31, 1998 includes the results of operations of RailWorks for the year ended
December 31, 1998 combined with (1) the results of operations for the Founding
Companies (other than Comstock Holdings, Inc.) from January 1, 1998 through July
31, 1998, (2) the results of operations of Armcore Railroad Contractors, Inc.
from January 1, 1998 through November 4, 1998, seven of the 1999 Acquired
Companies from January 1, 1998 through December 31, 1998, two of the 1999
Acquired Companies from December 1, 1997 through November 30, 1998 and two of
the 1999 Acquired Companies from April 1, 1998 through March 31, 1999 and (3)
the sale of the old notes and the application of the net proceeds, and give
effect to the pro forma adjustments related to these transactions all as if each
had occurred on January 1, 1998. The unaudited pro forma statement of operations
for the nine months ended September 30, 1999 includes the results of operations
of RailWorks for the nine months ended September 30, 1999 combined with (1) the
results of operations of FCM Rail, Ltd., F&V Metro Contracting Corp. and
affiliates and Gantrex Group from January 1, 1999 through January 31, 1999, the
results of operations of McCord Treated Wood, Inc. and Birmingham Wood, Inc.
from January 1, 1999 through April 12, 1999, the results of operations of
M-Track Enterprises, Inc. from January 1, 1999 through April 30, 1999, the
results of operations of PNR Contractors, Inc. from January 1, 1999 through May
18, 1999, the results of operations of Neosho Incorporated and affiliates from
January 1, 1999 through May 31, 1999, the results of operations of Earl Campbell
Construction Company, Inc. and Wood Waste Energy, Inc. from January 1, 1999
through June 30, 1999 and the results of operations of W. T. Byler Co., Inc.
from January 1, 1999 through September 30, 1999 and (2) the sale of the old
notes and the application of the net proceeds, and give effect to the pro forma
adjustments related to these transactions all as if each had occurred on January
1, 1999.


     We have analyzed the savings that we expect to realize from reductions in
salaries, bonuses and certain benefits to the owners of the Founding Companies
and the Acquired Companies. To the extent the owners of the Founding Companies
and the Acquired Companies have contractually agreed to changes in salaries,
bonuses, benefits and lease payments, these changes have been reflected in the
unaudited pro forma statement of operations.

     Certain pro forma adjustments are based on preliminary estimates, available
information and certain assumptions that management deems appropriate and may be
revised as additional information becomes available. The pro forma financial
data do not purport to represent what our combined financial position or results
of operations would actually have been if such transactions had in fact occurred
on those dates and are not necessarily representative of our combined financial
position or results of operations for any future period. Because the acquired
entities were not under common control or management prior to their acquisition
by RailWorks, historical combined results may not be comparable to, or
indicative of, future performance. The unaudited pro forma combined financial
statements should be read in conjunction with our historical consolidated
financial statements and the related notes included elsewhere in this
prospectus.

                             RAILWORKS CORPORATION

              NOTES TO UNAUDITED PRO FORMA STATEMENT OF OPERATIONS

     1. Excludes results of operations of the 1998 Acquired Companies from
November 4, 1998 to December 31, 1998 because they are included in the
Consolidated Financial Statements of RailWorks for the year ended December 31,
1998.

     2. To reflect the reduction of insurance and employee benefit costs
realized by RailWorks compared to the combined historical cost incurred by the
Founding Companies and the Acquired Companies.

     3. To reduce compensation expense to the level the owners of the Founding
Companies and the Acquired Companies have contractually agreed to receive
subsequent to the acquisition of their companies. The employment agreements are
generally for three years. This amount is net of incremental corporate expenses
of $1.6 million.

     4. To reflect the savings realized on a lease renewal by Comstock and a
reduction of compensation expense related to personnel of Comstock's former
parent.

     5. To eliminate acquisition-related costs incurred by the Founding
Companies and certain professional and other costs incurred by the Acquired
Companies in anticipation of their acquisition by RailWorks.

     6. To record the issuance of 1,205,872 shares of restricted common stock
(with no cash impact to RailWorks) to management, based on the IPO price of
$12.00 per share.

     7. To eliminate non-cash compensation expense recorded as a result of the
transfer of common stock from certain operating company managers to other
employees of such operating companies at the price per share in effect on the
date of transfer.

     8. To eliminate non-recurring expenses of RailWorks consisting of $2.9
million related to settlement of employee benefit obligations of one of the
operating companies and corporate relocation costs and $2.2 million in estimated
legal and settlement costs in connection with former operations of one of the
operating companies.

     9. To eliminate offering expenses incurred in connection with the IPO.

     10. To eliminate the loss related to the specific contract performance of
an unrelated venture which was guaranteed by one of the acquired companies.

     11. To record goodwill amortization expense using a 40-year estimated life,
other intangible assets amortization using a 10-year estimated life and loan
origination costs amortization using a 3-year estimated life.


     12. To reflect incremental interest expense related to the sale of the old
notes of 11  1/2%, and amortization of related discount and transaction fees of
$2.1 million over ten years, together with amortization of $4.8 million of
interest and transaction fees for the $125 million of existing notes issued
April 1, 1999.



     13. To adjust interest expense and interest income to reflect debt at the
rates that would have been in effect for RailWorks in 1998.


     14. To record the incremental provision for federal and state income taxes
at an assumed 39.0% effective tax rate increased by the effect of goodwill
amortization which is not deductible for income tax purposes.

     15. EBITDA is the sum of earnings before interest, income taxes,
depreciation and amortization expense. Included in EBITDA is income earned on
contract retainages pursuant to contractual agreements with certain customers.
EBITDA is presented because management believes that it is a widely accepted
financial indicator of a company's ability to service
                                       24

indebtedness. However, EBITDA does not represent net income or cash flow from
operations as defined by generally accepted accounting principles, is not
necessarily indicative of cash available to fund all cash flow needs, should not
be considered as an alternative to net income or to cash flows from operating
activities (as determined in accordance with generally accepted accounting
principles) and should not be construed as an indication of a company's
operating performance or as a measure of liquidity. EBITDA is not necessarily
comparable with similarly titled measures presented by other companies.

     The adjustments related to the 1999 Acquired Companies are based on
preliminary estimates of the allocation of the purchase price and are subject to
revision.

other costs incurred by the 1999 Acquired Companies in anticipation of their
acquisition by RailWorks.

     6. To record goodwill amortization expense using a 40-year estimated life.


     7. To reflect incremental interest expense related to the sale of the old
notes of 11 1/2% and amortization of related discount and transaction fees of
$2.1 million over ten years, together with amortization of $4.8 million of
interest and transaction fees for the $125 million of existing notes issued
April 1, 1999.


     8. To record the incremental provision for federal and state income taxes
at an assumed 39.0% effective tax rate increased by the effect of goodwill
amortization which is not deductible for income tax purposes.

     9. EBITDA is the sum of earnings before interest, income taxes,
depreciation and amortization expense. Included in EBITDA is income earned on
contract retainages pursuant to contractual agreements with certain customers.
EBITDA is presented because management believes that it is a widely accepted
financial indicator of a company's ability to service indebtedness. However,
EBITDA does not represent net income or cash flow from operations as defined by
generally accepted accounting principles, is not necessarily indicative of cash
available to fund all cash flow needs, should not be considered as an
alternative to net income or to cash flows from operating activities (as
determined in accordance with generally accepted accounting principles) and
should not be construed as an indication of a company's operating performance or
as a measure of liquidity. EBITDA is not necessarily comparable with similarly-
titled measures presented by other companies.

     The adjustments related to the 1999 Acquired Companies are based on
preliminary estimates of the allocation of the purchase price and are subject to
revision.

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


     The following discussion of the financial condition and results of
operations should be read in conjunction with our Consolidated Financial
Statements and the related notes appearing elsewhere in this prospectus.


     This discussion contains forward-looking statements made pursuant to the
safe harbor provisions of the Private Securities Litigation Reform Act of 1995,
which involve risks and uncertainties. Our actual results may differ from the
results discussed in the forward-looking statements. Factors that could cause or
contribute to those differences include, without limitation, those discussed in
this prospectus under "Business" and this "Management's Discussion and Analysis
of Financial Condition and Results of Operations", as well as those discussed
elsewhere in this prospectus.

GENERAL

     RailWorks Corporation was formed in March 1998 to become a leading
nationwide provider of rail system services, including construction and
rehabilitation, repair and maintenance, and related products. We primarily
perform services pursuant to contracts for the completion of specific projects,
some of which take up to five years to complete. On most projects, we contract
directly with rail system operators, while on other projects we act as a
subcontractor.


     In August 1998, we acquired in separate concurrent transactions 14 Founding
Companies engaged principally in the rail system services and products business
and we consummated our IPO. In November 1998, we acquired the two 1998 Acquired
Companies and, in the first ten months of 1999, we acquired the 11 1999 Acquired
Companies. In addition, in December 1999, we acquired two additional companies
engaged in the rail products and services and transit services businesses.
Except for the acquisition of Comstock Holdings, Inc., referred to as
"Comstock", a Founding Company, all of the acquisitions have been accounted for
as purchases in accordance with Accounting Principles Board No. 16.


     For accounting and financial statement purposes, Comstock has been
identified as the accounting acquirer consistent with the SEC's Staff Accounting
Bulletin No. 97 because its owners received the largest portion, 34.6%, of the
shares of common stock issued to the owners of the Founding Companies at the
time of their acquisition. The historical financial statements prior to August
4, 1998 are those of Comstock.

     Our consolidated balance sheet as of December 31, 1998, includes the
Founding Companies and the 1998 Acquired Companies. The results of operations
for the year ended December 31, 1998, and the statement of cash flows for the
year ended December 31, 1998 include the results of operations and cash flows of
Comstock for the entire period, the results of operations and cash flows of the
Founding Companies from August 1, 1998 and the results of operations and cash
flows of the 1998 Acquired Companies from November 4, 1998. RailWorks conducted
no operations prior to the consummation of its IPO other than the acquisitions
of the Founding Companies and the financing activities related thereto,
including the IPO, and had no revenue or operating expenses prior to August 1,
1998. Consequently, management believes that RailWorks, or individual Founding
Company and 1998 Acquired Company financial comparisons, are not meaningful.


     The Founding Companies and the Acquired Companies have operated
historically under varying tax structures, including both S and C corporations,
which have influenced the historical level of owners' compensation. Certain
executive officers of each of the Founding Companies and the Acquired Companies
have entered into employment agreements with the Company. The aggregate
compensation paid to such executive officers has been reduced as reflected in
the Unaudited Pro Forma Statement of Operations included elsewhere in this
prospectus. Following


                                       30
<PAGE>   36

the initial two-year term of the employment agreements, we will reevaluate our
compensation structure after examining operating results and the value of the
services those individuals provide us.

     Prior to their affiliation with RailWorks, the Founding Companies and the
Acquired Companies were privately owned and managed as separate entities.
Operating performance and management compensation depended on regional market
conditions and the priorities and strategies of individual owners. For example,
under private ownership these companies experienced limitations on project
bonding capacity, access to capital and human resources. In addition, many of
these companies operated under an S corporation tax structure. In many
instances, management and employee compensation was not necessarily directed
toward the achievement of growth in profitability. As part of RailWorks, these
businesses have access to significantly more resources, including higher bonding
capacity, lower input costs through greater purchasing power, access to lower
cost capital and cross-selling opportunities.

REVENUE AND COSTS

     RailWorks recognizes revenue from fixed price contracts using the
percentage-of-completion method, measured by the percentage of costs incurred to
date to management's estimate of total cost for each contract. Changes in job
performance, job conditions and estimated profitability may result in revisions
to cost and income, which are recognized in the period in which the revisions
are determined. Revenue from time-and-material contracts are recognized
currently as the work is performed.

     Contract costs consist principally of wages and benefits of employees,
subcontracted services, materials, parts and supplies, depreciation and other
vehicle expenses and equipment rental, as well as indirect costs related to
contract performance. Contract costs are charged to expense as incurred.
Provisions for estimated losses on uncompleted contracts are made in the period
in which such losses are determined.

     In the case of product sales, the Company recognizes revenue when products
are delivered to customers pursuant to shipping agreements. Cost of goods sold
includes raw materials cost and production cost.

RESULTS OF OPERATIONS


Historical -- Nine Months Ended September 30, 1999 Compared to Nine Months Ended
September 30, 1998



     Revenue.  Revenue increased $186.4 million, or 133.6%, from $139.5 million
for the nine months ended September 30, 1998 to $325.9 million for the nine
months ended September 30, 1999. The increase was due to the fact that the 1998
data is that of Comstock alone for seven months and all fourteen original
Founding Companies for the other two months in the period. The 1999 data
includes the Founding Companies as well as twelve additional companies acquired
since the IPO and prior to September 30, 1999.



     Transit service revenue increased $61.2 million, or 51.2%, from $119.6
million for the nine months ended September 30, 1998 to $180.8 million for the
nine months ended September 30, 1999. The increase was due to the fact that the
1998 data is that of Comstock alone for seven months and Comstock and one other
Founding Company for the other two months in the period. The 1999 data includes
two Founding Companies as well as three additional companies acquired since the
IPO and prior to September 30, 1999.



     Rail products and supplies revenue increased $28.8 million, or 533.3%, from
$5.4 million for the nine months ended September 30, 1998 to $34.2 million for
the nine months ended September 30, 1999. The increase was due to the fact that
the 1998 data is that of three Founding


                                       31
<PAGE>   37


Companies for two months in the period. The 1999 data includes three Founding
Companies as well as four additional companies acquired since the IPO and prior
to September 30, 1999.



     Rail construction revenue increased $96.4 million, or 664.8%, from $14.5
million for the three months ended September 30, 1998 to $110.9 million for the
nine months ended September 30, 1999. The increase was due to the fact that the
1998 data is that of nine Founding Companies for two months in the period. The
1999 data includes nine Founding Companies as well as five additional companies
acquired since the IPO and prior to September 30, 1999.



     Gross Profit.  Gross profit increased $50.3 million or 285.8% from $17.6
million for the nine months ended September 30, 1998 to $67.9 million for the
nine months ended September 30, 1999. The increase was due to the fact that the
1998 data is that of Comstock alone for seven months and all fourteen original
Founding Companies for the other two months in the period. The 1999 data
includes the Founding Companies as well as twelve additional companies acquired
since the IPO and prior to September 30, 1999. The gross profit percentage
increased from 12.6% for the nine months ended September 30, 1998 to 20.8% for
the nine months ended September 30, 1999. This increase was the result of higher
profitability associated with the mix and type of work performed during 1999 by
the consolidated group as compared to historical Comstock margins.



     Transit services gross profit increased $10.9 million or 77.9% from $14.0
million for the nine months ended September 30, 1998 to $24.9 million for the
nine months ended September 30, 1999. The increase was due to the fact that the
1998 data is that of Comstock alone for seven months and Comstock and one other
Founding Company for the other two months in the period. The 1999 data includes
two Founding Companies as well as three additional companies acquired since the
IPO and prior to September 30, 1999. The gross profit percentage increased from
11.7% for the nine months ended September 30, 1998 to 13.8% for the nine months
ended September 30, 1999. This increase was the result of higher profitability
associated with the mix and type of work performed during 1999 by the
consolidated group as compared to historical consolidated Founding Company
margins.



     Rail products and supplies gross profit increased $12.0 million, or
1,090.9%, from $1.1 million for the nine months ended September 30, 1998 to
$13.1 million for the nine months ended September 30, 1999. The increase was due
to the fact that the 1998 data is that of three Founding Companies for two
months in the period. The 1999 data includes three Founding Companies as well as
four additional companies acquired since the IPO and prior to September 30,
1999. The gross profit percentage increased from 20.4% for the nine months ended
September 30, 1998 to 38.3% for the nine months ended September 30, 1999. This
increase was the result of higher profitability associated with the mix and type
of work performed during 1999 by the consolidated group as compared to
historical consolidated Founding Company margins.



     Rail construction gross profit increased $27.4 million, or 1,096.0%, from
$2.5 million for the nine months ended September 30, 1998 to $29.9 million for
the nine months ended September 30, 1999. The increase was due to the fact that
the 1998 date is that of nine Founding Companies for two months in the period.
The 1999 data includes nine Founding Companies as well as five additional
companies acquired since the IPO and prior to September 30, 1999. The gross
profit percentage increased from 17.2% for the nine months ended September 30,
1998 to 27.0% for the nine months ended September 30, 1999. This increase was
the result of higher profitability associated with the mix and type of work
performed during 1999 by the consolidated group as compared to historical
consolidated Founding Company margins.



     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased $19.7 million or 169.8%, from $11.6 million
for the nine months ended September 30, 1998 to $31.3 million for the nine
months ended September 30, 1999. The increase is due to the fact that the 1998
data is that of Comstock alone for seven months and all original Founding

                                       32
<PAGE>   38


Companies for the other two months in the period. The 1999 data includes the
Founding Companies as well as twelve additional companies acquired since the IPO
and prior to September 30, 1999. Also recorded during the nine months ended
September 30, 1998 were one time non-recurring expenses of $20.0 million and IPO
transaction fees of $1.3 million. There were no similar items recorded during
the nine months ended September 30, 1999. As a percentage of revenue, selling,
general and administrative expenses increased from 8.3% for the nine months
ended September 30, 1998 to 9.6% for the nine months ended September 30, 1999.
This percentage increase was a result of acquired companies having higher
overhead selling, general and administrative cost structures than Comstock.



     Transit services selling, general and administrative expenses increased
$1.8 million or 18.4%, from $9.8 million for the nine months ended September 30,
1998 to $11.6 million for the nine months ended September 30, 1999. The increase
was due to the fact that the 1998 data is that of Comstock alone for seven
months and Comstock and one other Founding company for the other two months in
the period. The 1999 data includes two Founding Companies as well as three
additional companies acquired since the IPO and prior to September 30, 1999. As
a percentage of segment revenue, selling, general and administrative expenses
decreased from 8.2% for the nine months ended September 30, 1998 to 6.4% for the
nine months ended September 30, 1999. This percentage decrease was a result of
acquired companies having lower overhead selling, general and administrative
cost structures than Comstock.



     Rail products and supplies selling, general and administrative expenses
increased $5.1 million, or 1,700.0%, from $276,000 for the nine months ended
September 30, 1998 to $5.4 million for the nine months ended September 30, 1999.
The increase was due to the fact that the 1998 data is that of three Founding
Companies for two months in the period. The 1999 data includes three Founding
Companies as well as four additional companies acquired since the IPO and prior
to September 30, 1999. As a percentage of segment revenue, selling general and
administrative expenses increased form 5.6% for the nine months ended September
30, 1998 to 15.8% for the nine months ended September 30, 1999. This percentage
increase was a result of acquired companies having higher overhead selling,
general and administrative cost structures than the Founding Companies.



     Rail construction selling, general and administrative expenses increased
$8.1 million, or 675.0%, from $1.2 million for the nine months ended September
30, 1998 to $9.3 million for the nine months ended September 30, 1999. The
increase was due to the fact that the 1998 data is that of nine Founding
Companies for two months in the period. The 1999 data includes nine Founding
Companies as well as five additional companies acquired since the IPO and prior
to September 30, 1999. As a percentage of segment revenue, selling, general and
administrative expenses increased from 8.3% for the nine months ended September
30, 1998 to 8.4% for the nine months ended September 30, 1999. This percentage
increase was a result of acquired companies having higher overhead selling,
general and administrative cost structures than the Founding Companies.



     Corporate selling, general and administrative expenses increased $4.7
million, or 1,566.7%, from $300,000 for the nine months ended September 30, 1998
to $5.0 million for the nine months ended September 30, 1999. The increase was
due to the fact that the 1998 data is that of an overhead structure to support
all fourteen Founding Companies for two months in the period. The 1999 data is
that of an overhead structure to support all fourteen Founding Companies as well
as twelve additional companies acquired since the IPO and prior to September 30,
1999. As a percentage of total revenue, selling, general and administrative
expenses increased from .2% for the nine months ended September 30, 1998 to 1.5%
for the nine months ended September 30, 1999. The increase was due to the fact
that the 1998 data is that of an overhead structure to support all fourteen
Founding Companies. The 1999 data is that of an overhead structure to support
all fourteen Founding Companies as well as twelve additional companies acquired
since the IPO and prior to September 30, 1999.

     Net Income.  Net income increased $31.4 million, from a loss of $17.9
million for the nine months ended September 30, 1998 to a profit of $13.5
million for the nine months ended September 30, 1999, as a result of the items
mentioned above.



Historical -- Year Ended December 31, 1998


     Revenue was $212.5 million for the year ended December 31, 1998. Cost of
revenue was $182.8 million. Gross profit for the year ended December 31, 1998
was $29.7 million. Selling, general and administrative expenses were $38.3
million, including non-recurring expenses of $20.0 million and transaction fees
of $1.3 million recorded during the third quarter related to the IPO. The $20.0
million of non-recurring expenses consists of a non-cash compensation charge of
$14.9 million for stock grants issued to management resulting from the
consummation of the IPO, $2.9 million related to the settlement of certain
employee benefit obligations and relocation expenses and $2.2 million for
estimated legal and settlement costs in connection with certain claims and
litigation associated with our former west coast operations. Included in other
income in the fourth quarter was a gain of $861,000 on the disposition of our
Longview, Washington industrial electrical contracting division. This
divestiture was in conjunction with Comstock's change in strategic focus to
rail-based transit projects. The net loss for the year ended December 31, 1998
was $12.8 million.

Pro Forma Founding Companies -- Year Ended December 31, 1998 Compared to the
Year Ended December 31, 1997

     The presentation below provides the pro forma results of operations of the
Founding Companies as if the Founding Companies had been acquired on January 1,
1997. The presentation only includes the results of the 1998 Acquired Companies
from November 4, 1998 to December 31, 1998. Acquired Companies are otherwise
excluded. The presentation includes pro forma results of the Founding Companies
and the Acquired Companies on a combined basis, see Pro Forma Financial
Statements beginning on page 21.

     The pro forma results of operations of RailWorks for the periods presented
may not be comparable to, and may not be indicative of, our actual results of
operations because (1) the Founding Companies and the Acquired Companies were
not under common control or management during the periods presented and (2) the
pro forma data do not reflect all of the potential benefits and cost savings
RailWorks expects to realize as a result of operating as a combined entity. The
following discussion should be read in conjunction with the Unaudited Pro Forma
Financial Statements and the related notes appearing elsewhere in this
prospectus.

     The following table sets forth selected pro forma financial data for the
periods indicated.

     Revenue.  Revenue increased $13.0 million, or 5.1%, from $256.5 million for
the year ended December 31, 1997 to $269.5 million for the year ended December
31, 1998. The increase was primarily due to growth of the Company's transit
services segment, which grew at 7.1% and represented $11.0 million in additional
revenue.

     Gross Profit.  Gross profit increased $5.3 million, or 14.4%, from $37.1
million for the year ended December 31, 1997 to $42.4 million for the year ended
December 31, 1998. As a percentage of revenue, gross profit increased to 15.8%
for the year ended December 31, 1998 from 14.5% for the year ended December 31,
1997. The increase in gross profit was due to the higher revenue base and
improved revenue mix as a result of higher margin contracts.

     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses decreased $1.5 million, or 7.3%, from $20.8 million for
the year ended December 31, 1997 to $19.3 million for the year ended December
31, 1998. As a percentage of revenue, selling, general and administrative
expenses decreased from 8.1% for the year ended December 31, 1997 to 7.2% for
the year ended December 31, 1998. The decrease in selling, general and
administrative expenses was the result of decreased salaries and wages during
1998.

     Net Income.  Net income increased to $8.8 million for the year ended
December 31, 1998 from $5.4 million for the year ended December 31, 1997, an
increase of $3.4 million, or 62.0%. As a percentage of revenue, net income
increased to 3.3% for the year ended December 31, 1998 from 2.1% for the year
ended December 31, 1997. The increase was the result of the increase in revenue
and profitability discussed above.

Historical -- December 31, 1997 Compared to December 31, 1996 -- Comstock
Holdings, Inc.

     Founded in 1904, L.K. Comstock & Co., Inc. ("L.K. Comstock"), a
wholly-owned subsidiary of Comstock, is one of the largest electrical
contractors in the United States based on revenue. L.K. Comstock specializes in
power, communication and signaling installations for rail-based transit systems
and also provides electrical contracting services for commercial buildings,
heavy industrial and manufacturing plants and power plants. Through incremental
investments from 1986 through 1989, L.K. Comstock's former parent company,
Comstock Group, Inc. ("CGI"), was acquired by Spie Enertrans S.A. ("Spie"), a
multinational electrical engineering firm headquartered in Paris, France. During
Spie's ownership, L.K. Comstock sought to increase revenue by expanding its
non-transit operations in California and entering into joint ventures to design
and build large power and industrial projects in other locations. Effective
January 1, 1997, L.K. Comstock was acquired (the "Comstock Acquisition") from
Spie by Comstock, a corporation owned by certain employees of L.K. Comstock.

     Following the Comstock Acquisition, Comstock's management instituted a plan
to reduce Comstock's costs and improve profitability. As a result of this plan,
Comstock has reduced general and administrative expenses by eliminating certain
management positions, including those of several French expatriates, and
reducing its Los Angeles-based staff. Comstock also improved gross profit
margins through (1) improved control over contract costs by consolidating
transit project estimating and bidding functions and (2) exiting unprofitable,
risky operations which had been expanded under Spie's ownership (such as
electrical projects for traffic systems, non-rail projects in California and
large joint ventures for the design and construction of power and industrial
plants). Under joint ventures with general construction contractors, as
preferred by Spie, Comstock had limited management control and was subject to
increased costs due to general contract conditions. Following the Comstock
Acquisition, management focused the business to benefit from its core
competencies, including rail-based transit projects. However, Comstock's
electricians and supervisors are capable of performing services on rail and
non-rail projects, thus enabling the efficient use of experienced labor on
projects in response to demand. Additionally, its accounting and management
systems are designed to provide necessary information for both rail and non-rail
projects. In 1997, Comstock derived 56.7% of its revenue

                                       35
<PAGE>   41

and 58.6% of its gross profit from rail-related projects as compared to 48.1%
and 48.5%, respectively, in 1996.

     Revenue.  Revenue decreased to $153.6 million for the year ended December
31, 1997 from $188.8 million for the year ended December 31, 1996, a decrease of
$35.2 million, or 18.6%. This decrease was due to a decrease in revenue from
Comstock's power and industrial operations attributable to the completion of
certain large projects in 1996 and early 1997 that were not immediately
replaced, as well as a decrease in revenue from Comstock's traffic operations,
offset in part by an increase in revenue from Comstock's commercial operations.
The decrease in revenue from traffic operations, as well as a portion of the
decrease in revenue from power and industrial operations, were due to the change
in strategic focus discussed above and it is unlikely that such projects will be
replaced. Rail-related revenue did not change significantly from 1996 to 1997
due to limited bonding capacity.

     Gross Profit.  Gross profit decreased to $16.9 million for the year ended
December 31, 1997 from $19.5 million for the year ended December 31, 1996, a
decrease of $2.5 million, or 13.0%. As a percentage of revenue, gross profit
increased to 11.0% for the year ended December 31, 1997 from 10.3% for the year
ended December 31, 1996. Gross profit decreased as a result of the decline in
revenue, offset in part by tighter cost controls implemented by management and a
reduction in the amount of activity in traffic and Los Angeles-based non-rail
projects which had significantly lower margins. Additionally, 1996 gross profit
benefited from a reduction in contract reserves of approximately $3.0 million
related to the settlement of outstanding project contingencies.

     General and Administrative Expenses.  General and administrative expenses
decreased to $13.7 million for the year ended December 31, 1997 from $15.1
million for the year ended December 31, 1996, a decrease of $1.3 million, or
8.8%. This decrease was a result of the tighter cost controls implemented by
management, including reductions in executive and administrative staff in the
power, industrial and Los Angeles-based non-rail operations. As a percentage of
revenue, general and administrative expenses increased to 8.9% for the year
ended December 31, 1997 from 8.0% for the year ended December 31, 1996. This
increase was the result of the decrease in revenue.

     Net Income.  Net income increased to $1.4 million for the year ended
December 31, 1997 from $58,000 for the year ended December 31, 1996, an increase
of $1.3 million. For each period, net income as a percentage of revenue was less
than 1%. The increase in net income was partially due to the reduction of
general and administrative expenses discussed above and the elimination of
management expenses of $941,000 paid to Spie and related entities in 1996. In
addition, as a result of the Comstock Acquisition and the related purchase
accounting, approximately $1.6 million of depreciation and amortization were
eliminated in 1997 as compared to 1996. These factors were partially offset by
the decrease in gross profit due to the factors discussed above.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK


     RailWorks is subject to market risk associated principally with changes in
interest rates. Interest rate exposure has been principally limited to the $30.0
million of long-term debt under our revolving credit agreement outstanding at
September 30, 1999. All of that debt is priced at interest rates that float with
the market. A 50 basis point movement in the interest rate on the floating rate
debt would have resulted in an approximate $150,000 annualized increase or
decrease in interest expense and cash flows. The remaining debt is fixed-rate
debt. RailWorks may from time to time enter into interest rate swaps on its
debt, when it believes there is a clear financial advantage for doing so.
RailWorks does not use derivative financial or commodity instruments for trading
purposes and the use of such instruments is subject to strict approval levels by
senior officers. Typically, the use of such derivative instruments is, in the
aggregate, not


                                       36
<PAGE>   42


material to our financial position, results of operations and cash flows. At
September 30, 1999, there were no swaps outstanding.



FLUCTUATIONS IN QUARTERLY OPERATING RESULTS


     The Founding Companies and the Acquired Companies have in the past
experienced quarterly variations in revenue, operating income (including
operating losses), net income (including net losses) and cash flows (including
operating cash flow deficits) as a result of various factors, including projects
commenced and completed during a quarter, the number of business days in a
quarter and the size and scope of projects. A variation in the number of
projects, progress on projects or the timing of the initiation or completion of
projects can cause periods in which certain operating resources are not
generating revenue and can cause significant variations in operating results
between reporting periods. Negative fluctuations have been particularly
pronounced, and net losses have been incurred, in the first and fourth calendar
quarters, generally due to adverse weather conditions. We expect to continue to
experience such quarterly fluctuations in operating results, including possible
net losses. See "Risk Factors -- Risks Relating to RailWorks -- Certain
Operating Companies Have a History of Losses" and "-- The Rail System Industry
is Cyclical".

LIQUIDITY AND CAPITAL RESOURCES

     On August 4, 1998, we completed the IPO of 5.0 million shares of its common
stock at a price of $12.00 per share. We raised approximately $52.5 million of
capital, net of underwriting discounts and other offering expenses, of which
approximately $51.1 million was used for the cash portion of our acquisitions of
the Founding Companies and approximately $1.4 million was used for the repayment
of debt.


     At September 30, 1999, RailWorks had working capital of approximately
$109.8 million, a $42.4 million increase from December 31, 1998 when working
capital was $67.4 million. Net cash used in operating activities was
approximately $24.5 million for the nine months ended September 30, 1999. Net
cash used in investing activities was approximately $104.7 million for the nine
months ended September 30, 1999, which included $89.2 million of cash for
acquisitions. Net cash provided by financing activities for the nine months
ended September 30, 1999 was approximately $131.6 million, which included $173.9
million from the issuance of the existing and old notes. Also included in
financing activities was $28.6 million from the issuance of long-term
borrowings, offset by debt repayment of approximately $45.9 million from
long-term borrowings and net repayments of $19.3 million on the RailWorks credit
facility.



     At December 31, 1998, RailWorks had working capital of approximately $67.4
million. Net cash used in operating activities for the year ended December 31,
1998, was approximately $13.9 million. Net cash used in investing activities for
the year ended December 31, 1998 was approximately $54.3 million which consisted
of $52.5 million of cash for acquisitions (including $49.5 million for the
Founding Companies) and $1.3 million for purchase of equipment and leasehold
improvements. Net cash provided by financing activities for the year ended
December 31, 1998 was approximately $70.0 million, which included $52.5 million
from the issuance of common stock relating to the IPO and borrowings of
approximately $61.3 million, offset by debt repayment of approximately $41.2
million.



     Capital expenditures were $11.8 million, $1.3 million, $448,000 and
$690,000 in the nine months ended September 30, 1999, fiscal 1998, 1997 and
1996, respectively. Historically, capital expenditures have been, and future
expenditures are anticipated to be, primarily to support expansion of our
operations, including its management information systems. Our capital
expenditures over the next several years, as a percentage of its revenues, are
expected to decrease compared to those of the past three fiscal years.


                                       37
<PAGE>   43


     We anticipate capital expenditures of approximately $2.5 million for
equipment and leasehold improvements over the balance of 1999. This investment,
which we expect to finance primarily by working capital and vendor financing,
relates to the anticipated facility consolidations of the operating companies,
the installation of a comprehensive financial reporting computer system and the
purchase of supplemental machinery and equipment needed to meet operational
demands. We have no other significant commitments for future capital
expenditures, although it is likely that cash outflows for business acquisitions
and equipment leases will continue.



     Cash for acquisitions and working capital are financed by funds generated
from operations, together with borrowings under our $105 million credit facility
with NationsBank, N.A. At September 30, 1999, on an actual basis, we had $30.0
million of borrowings outstanding under the credit facility, which bore interest
at a weighted average annual rate of 9.0% as of such date. As of September 30,
1999, pro forma for the 1999 Acquired Companies, borrowings under our new term
loan facility, and the sale of the old notes and the application of the net
proceeds, we would have had approximately $82.5 million available for borrowing
under our credit facility. The credit facility is secured by a first lien on all
of the capital stock of our subsidiaries and on all accounts receivable of
RailWorks and its subsidiaries. The credit facility contains a negative pledge
on all of our other assets and the assets of our subsidiaries and other usual
and customary covenants and events of default for transactions of the type
contemplated by the credit facilities. Borrowings under the credit facility bear
interest, at our option, at an interest rate equal to



     - LIBOR plus the applicable margin for LIBOR loans, which ranges from 125
       basis points to 250 basis points based on the ratio of Funded Debt to
       EBITDA, as such terms are defined in the credit facility, or



     - the Alternate Base Rate, which is defined as the higher of (1) the
       NationsBank prime rate and (2) the Federal Funds rate plus 50 basis
       points, plus up to 125 basis points based on the ratio of Funded Debt to
       EBITDA.


We may also finance future acquisitions with shares of common stock and
contingent consideration.


     In addition, on November 5, 1999, we entered into a term loan facility with
the lenders named therein. Under the term loan facility, at December 6, 1999, we
had $30.0 million of borrowings outstanding, which bore interest at a weighted
average annual rate of 9.83% as of such date. Borrowings outstanding under the
term loan facility mature on November 5, 2004. Borrowings under the term loan
facility bear interest, at our option, at an interest rate equal to (1) the Base
Rate plus 200 basis points or (2) the Eurodollar Rate plus 375 basis points. The
interest rate is increased by 2% upon the occurrence, and during the
continuance, of an event of default. The term loan facility is guaranteed by all
of our domestic subsidiaries.


     In connection with some acquisitions, we have agreed, and in the future may
agree, to pay additional consideration based on operating results of the
acquired entity. The payment of any such earnouts could result in an increase in
the purchase prices of such acquisitions and, as a result, additional goodwill.


     We believe that funds generated from operations, together with existing
cash, the net proceeds of this offering and borrowings under our credit
facility, will be sufficient to finance its current operations, planned capital
expenditures, pending acquisitions and internal growth for at least the next
several years. If we were to make a significant acquisition for cash, it may be
necessary for us to obtain additional debt or equity financing.

INFLATION

     We do not believe that inflation has had a material effect on its results
of operations in recent years. However, there can be no assurance that our
business will not be affected by inflation in the future.

YEAR 2000


     The Company developed a plan for year 2000 issues, which addressed three
main areas: (1) information systems; (2) embedded chips; and (3) supply chain
readiness (including customers as well as inventory and non-inventory
suppliers). To oversee the process, the Company established a committee
comprised of accounting and information systems personnel who reported regularly
to the board of directors and the Audit Committee.



     The evaluation of the Company's state of readiness relating to its year
2000 issues has been a continual process emphasizing a constant awareness of
computer systems and business relationships that may be sensitive to year 2000
issues. Management categorized the activities necessary to solve the year 2000
issues into the identification and assessment phase, the remediation phase, and
the testing and contingency planning phase. The identification and assessment
phase included conducting a comprehensive inventory and evaluation of all the
Company's IT systems and non-IT electronic equipment (collectively referred to
as a computer programs) to identify those computer programs that contained date
sensitive features. Those computer programs that contained such features were
then further evaluated and categorized as either mission critical or non-mission
critical based upon their relative importance to the uninterrupted continuation
of the Company's daily operations. Mission critical computer programs gained top
priority when allocating the available resources to solve year 2000 issues.



     The Company has substantially completed the identification, assessment,
remediation, and testing of its internal information systems and other equipment
with date sensitive operating controls, such as manufacturing equipment, HVAC,
security and other similar systems.



     The Company has also been in communication with hardware and software
vendors with whom the Company transacts business, third parties with whom the
Company exchanges information electronically, major or sole source suppliers,
government agencies, and major customers. The focus of these communications has
been to determine the state of readiness of each of these third parties with
respect to their own year 2000 issues and how their progress may impact the
Company. The majority of responses received from third party inquiries indicate
that they are working on their year 2000 issues, but the responses do not
provide specific details. Follow-up action related to material third party
inquiries and responses is expected to continue. However, the Company has no
means of ensuring that third parties with whom it deals will be year 2000
compliant or that the information obtained from such third parties regarding
year 2000 compliance will prove to be accurate.



     While the Company's management anticipates that all computer systems have
been assessed, remedied and tested, there can be no assurance that all will be
completely error free and that such programs will be compliant by year 2000. We
rely on third party software, equipment and services to conduct our business.
While the Company believes it has made reasonable efforts to address this issue,
it has no means of ensuring that third parties with whom it deals will be year
2000 compliant or that the information obtained from such third parties
regarding year 2000 compliance will prove to be accurate.



     The Company believes that it is difficult to specifically identify the most
reasonably likely worst case year 2000 scenario. The failure to correct a
material year 2000 problem or the inability of any key customer, key supplier or
a governmental agency to make the necessary computer system changes on a timely
basis, the inaccuracy of responses received from these third parties, and the
potential shortage of skilled human resources to install and test upgraded
software and


                                       39
<PAGE>   45


equipment could result in interruptions to Company operations or business
activities. Due to the general uncertainty inherent in the year 2000 issue,
particularly as it relates to the readiness of the Company's key customers and
suppliers, and of governmental agencies, the Company cannot ascertain whether
the consequences of the year 2000 failures will have a material impact on the
Company's results of operations, liquidity or financial condition. The Company's
insurance coverage is limited to business interruption resulting from fire,
explosion, or related perils which are caused by a year 2000 system failure.



     Based upon the Company's current estimates, remaining incremental
out-of-pocket costs of its year 2000 program are expected not to exceed $10,000.
As of September 30, 1999, the Company had spent an aggregate of $40,000 on its
year 2000 program. These costs were expensed as incurred. These costs did not
include internal management time and the deferral of other projects, the effects
of which were not material to the Company's results of operations or financial
condition.



     The Company's year 2000 efforts are ongoing and its consideration of
contingency plans will continue to evolve as new information becomes available.
While the Company anticipates continuity of its business activities, that
continuity will be dependent upon its ability, and the ability of third parties
upon whom the Company relies on directly or indirectly, to be year 2000
compliant.

                                    BUSINESS

OVERVIEW

     RailWorks Corporation is a leading provider of integrated rail system
services and products to a diverse base of customers throughout the United
States. Management believes RailWorks is positioned to grow significantly due to
its ability to comprehensively design, supply, construct and maintain rail
systems. We base our strategy on providing a full range of rail-related services
and products on a "turnkey" basis throughout North America and offering rail
system solutions under the "RailWorks" brand. RailWorks provides track
construction, rehabilitation, repair, maintenance and operations; rail
electrification and installation of communication and signaling systems; and
related products and supplies. We provide these services to a wide variety of
customers, including Class I and shortline railroads, publicly funded transit
authorities and commercial and industrial companies. RailWorks also provides
non-rail products and services such as electrical contracting, bridge and
highway support structures and related concrete products.

INDUSTRY OVERVIEW

     The rail passenger and freight industries have undergone significant
changes in recent years. Changes in the industry have affected Class I
railroads, shortline and regional railroads, passenger railroads and transit
systems. In addition, industrial and other commercial companies that own and
maintain their own rail systems have become more focused on transportation
logistics and achieving cost efficiencies. These changes have resulted in an
ongoing reconfiguration of the country's rail infrastructure, significant new
construction projects and emerging demand for outsourced construction,
rehabilitation, repair and maintenance services.

     Total Expenditures.  Based on information published by the Association of
American Railroads (the "AAR") and the American Public Transit Association
("APTA"), management estimates that expenditures by rail system operators for
domestic new construction, rehabilitation, repair and maintenance were
approximately $16 billion in 1998. Management estimates that the breakdown of
expenditures was as follows:

                            (EXPENDITURES PIE CHART)

     We also believe that expenditures for these services outside the United
States have increased significantly in recent years as a result of
infrastructure construction and modernization programs, as well as privatization
of large rail systems. In many instances, foreign governments and companies have
sought the expertise of designers, engineers and construction managers in the
United States.

     Class I Railroads.  According to the AAR, Class I track usage (defined as
tons shipped per track mile) has increased significantly from 4.7 million in
1988 to 7.8 million in 1997,
                                       41
<PAGE>   47

representing a 5.9% compound annual growth rate. As a result of industry
consolidation, there are only eight Class I railroads, as defined by the Surface
Transportation Board, operating in the United States today, compared to 27 in
1980. These railroads are Burlington Northern Sante Fe Railway, CSX
Transportation, Kansas City Southern Lines, Norfolk Southern Railway Company,
Union Pacific Railroad, Canadian National, Canadian Pacific and Consolidated
Rail Corporation. According to the AAR, these railroads accounted for 71% of the
rail mileage operated in the United States and 91% of railroad revenue in 1997.
In recent years, the Class I railroads have sought to rationalize their systems,
for example by "double-tracking" certain high traffic main lines and abandoning
portions of their systems that generate lower volumes of traffic. Mergers of
Class I systems have also created significant construction projects as the
systems are reconfigured and integrated. Historically, the major railroads have
been vertical organizations that sought to perform their own construction and
maintenance by utilizing specialized workforces and equipment for these
functions. Management believes that as Class I railroads seek to continue to
improve their cost structures, they will increasingly continue to outsource
certain construction and maintenance functions to independent contractors.

     Shortline and Regional Railroads.  In recent years, the number and coverage
of shortline and regional railroads, i.e., those railroads which are not Class I
railroads, have increased significantly. The Staggers Rail Act of 1980 provided
for partial deregulation of the railroad industry and created mechanisms by
which larger railroads could more easily dispose of portions of rail line. Since
that time, the larger railroad systems in the United States have streamlined
their operations by disposing of portions of their systems that generate lower
volumes of traffic and other companies have acquired portfolios of shortline
railroads. According to the AAR, there are approximately 550 shortline and
regional railroads, which in the aggregate generated approximately 9% of all
railroad revenue in 1997. The percentage of total track miles operated by
shortline and regional railroads in the United States increased to 29% in 1997
from approximately 17% in 1986. Shortline and regional railroads spend a
relatively large portion of their capital and operating budgets on maintenance
of their track assets, because these assets are often in poor condition when
they are acquired. These railroads typically utilize independent contractors for
their maintenance and construction programs, because they do not have systems
large enough to support the purchases of equipment and development of workforces
that would be required for these functions.

     Passenger Rail Transit Services.  The growth of major metropolitan areas
and the aging of existing rail systems have resulted in significant developments
in passenger rail transit services. Heavy rail, commuter rail (service between
metropolitan and suburban areas) and light rail (typically, short trains
operating on rights-of-way that are not separated from other traffic) have
emerged as attractive alternatives to bus or automobile transit and older
commuter rail systems have been rehabilitated and extended to handle increased
ridership. Many older urban systems (such as the New York City subway system)
are undergoing significant rehabilitation and/or modernization, while major
heavy rail systems built in the 1970s (such as the systems in San Francisco and
Atlanta) are being extended and upgraded. Additionally, there have been several
recent initiatives to develop high-speed rail transit networks between major
urban areas (for example, in Florida and the Northeast corridor). According to
APTA, there are now 18 commuter rail agencies in 14 urban areas, 14 heavy rail
agencies in 11 urban areas and 23 light rail agencies nationwide. According to
APTA, commuter and light rail ridership has increased 30% and 99%, respectively,
from 1985 to 1997. Since 1979, approximately 16 cities have constructed new
light rail-based transit systems and other cities have either extended or
refurbished their existing systems, with ridership increasing by approximately
150% over the period from 1978 through 1996. In June 1998, the President signed
the Transportation Equity Act for the 21st Century ("TEA 21"), which is expected
to provide $42 billion of funds for transit projects through 2003. See
"Government Regulation -- TEA 21." This represents more than a 50% increase of
funding from the previous six-year period. According to APTA, in 1997, 53.7% of
transit spending was derived from federal funding with the balance derived from
state and local sources. Accordingly,
                                       42
<PAGE>   48

opportunities to provide rail-related signaling, communication, electrical and
track system construction, rehabilitation, repair and maintenance services for
transit systems have increased and are expected to continue to increase
significantly.

     Industrial Companies.  Companies install trackwork in their plants to
transport raw materials, equipment and finished goods. This trackwork consists
of connector lines that provide access to Class I or shortline railroads and
railyards to coordinate the shipment and delivery of cargo to and from their
plants. Companies are responsible for maintaining their own track and typically
construct and reconfigure trackage as part of plant construction and expansion.
Companies seek to optimize their track infrastructure in order to (1) reduce the
risk of accidents that can cause delays, property damage, and environmental
spills, (2) gain access to competing railroads to drive down costs and (3)
reduce transportation costs by minimizing the switching of railcars which is
time consuming and expensive. Such companies generally do not have the internal
resources to perform these services and typically use independent contractors to
design, construct and maintain these rail lines.

COMPETITIVE STRENGTHS

     Breadth of Services and Products.  Management believes that RailWorks
offers a broader range of services and products than most industry participants.
We believe that larger rail system operators are seeking to establish
relationships with contractors that specialize in rail system services and
products and that can provide efficient, integrated solutions over the entire
life cycle of their assets. We further believe that rail system operators and
industrial companies increasingly seek to enter into arrangements with a smaller
number of companies that can provide integrated services on a national or
regional basis, in order to ensure centralized management of their rail assets,
adherence to uniform quality standards and more cost-effective procurement
practices. We cross-sell our services and products by combining the strengths of
the operating companies to provide its customers with integrated rail system
solutions. For example, we combine our design and engineering services with
track construction to offer a turnkey approach to track construction projects.
Our ability to bundle services, including construction, rehabilitation and
maintenance, under a single contract has allowed us to compete more effectively
against companies that provide a more limited range of services.

     Expansive Geographic Coverage.  Our 48 operating facilities provide us with
expansive geographic coverage that enables us to reach customers throughout
North America. These multiple facilities enable us to undertake projects more
cost effectively than we could without local facilities. RailWorks can perform
projects at multiple locations for our national account customers, enabling our
customers to use a single company for rail system projects throughout the United
States and Canada. We also can allocate equipment and technical specialists
throughout the United States and Canada to maximize asset utilization, satisfy
regional demand and complete projects in remote locations. We believe our broad
geographic presence reduces the impact of local and regional economic cycles,
and reduces weather-related or seasonal variations in our business.

     Significant Market Presence.  In an industry that has traditionally been
comprised of regional competitors, we believe our size gives us a competitive
advantage. Our substantial contract bonding capacity allows us to bid on
additional projects and more substantial projects to which smaller companies may
not have access. Our ability to bid on these additional projects has allowed us
to significantly increase our project backlog since August 1998. In addition,
our size provides significant economies of scale in terms of materials
purchasing, capital expenditures and administrative costs.

     Diverse Sources of Revenue.  We derive a significant portion of our revenue
from public transit authorities whose funding is appropriated from federal,
state and local sources which makes those funds less sensitive to economic
cycles. In addition, a portion of our work is related

                                       43
<PAGE>   49


to government-mandated safety standards and we therefore cannot postpone it. We
sell our services through a large number of individual contracts. No contract
accounted for more than 3.5% of our pro forma revenue for the year ended
December 31, 1998. More than half of our contracts have a duration in excess of
one year, providing us with a significant source of future revenue. We have
strong relationships with a wide variety of customers, including:


     Class I railroads that have utilized RailWorks for repair and maintenance,
construction or engineering and supply:

     - CSX Transportation

     - Union Pacific Railroad

     - Burlington Northern Santa Fe Railway

     - Canadian National Railway

     Shortline and regional railroads that have contracted with RailWorks for
track construction and maintenance work or product supply:

     - Alaska Railroad Corp.

     - Louisville & Indiana Railroad

     - Indiana Southern Railroad Company

     - Indiana & Ohio Rail Systems

     Publicly funded transit authorities that have contracted with RailWorks for
electrical installations, signaling, communications and station projects:

     - New York City Transit Authority

     - New York Department of Transportation

     - Los Angeles Metropolitan Transit Authority

     - Connecticut Department of Transportation Rail Division

     Commercial and industrial companies that have contracted with RailWorks for
track construction and maintenance and non-rail electrical contracting work:

     - United States Steel

     - Bethlehem Steel

     - Morse Diesel

     - Babcock & Wilcox


     Experienced Management.  Our senior operating managers have an average of
26 years of experience in the rail services and products industry, and many of
them are or have previously served as leaders of industry trade groups. We use a
corporate management structure that allows these senior managers to focus on
marketing and growing their operations instead of administrative
responsibilities. Management has created a culture of cooperation and teamwork
among the operating companies that emphasizes dissemination of best practices
among our regional and local management teams. For example, management believes
that RailWorks can successfully implement best practices in the areas of 24-hour
emergency rerailment services, annual maintenance contracts and efficient
inventory management.

STRATEGY

     Key elements of our strategy include the following:

     Capitalize on Scale and Geographic Coverage.  By combining the operations
of the Founding Companies and the Acquired Companies, we have achieved greater
size and scope than regional and local contractors. We believe that we will be
able to achieve continued internal growth by building our national accounts
program to serve rail customers with multiple sites and by enhancing our sales
and marketing programs. Management expects to leverage our geographic network
and greater bonding capacity to increase our business. We currently have very
limited international operations but over time we may increase our activity in
international markets, where privatizations of railroads and large transit
projects are creating increased demand for sophisticated design and construction
management services. We also share equipment and labor while managing multiple
work sites. We believe that this process of sharing resources and our
comprehensive bidding capabilities enable us to compete more effectively.

     Utilize Cross-selling.  The Founding Companies and the Acquired Companies
have provided RailWorks with a broad range of rail-related services and
products. We intend to leverage our existing customer base to "cross-sell" these
services and products. For example, we will seek to provide additional track
construction and maintenance services to Class I railroads who are already
significant buyers of our track supplies. We also intend to continue to
emphasize the marketing of rail maintenance programs, which provide recurring
revenue and strengthen customer relationships. We have been successful in
leveraging our maintenance relationships to obtain new rail system installation
projects. In addition, by placing a stronger emphasis on our design and
engineering services we expect to gain access to more track construction
opportunities.


     Expand Through Acquisitions.  Management believes RailWorks is
well-positioned to capitalize on the consolidation of the rail system services
and products industry on a regional and nationwide basis. We have created an
efficient operating platform that management expects will facilitate the
integration of future acquisitions. Our acquisition program includes expanding
geographic coverage throughout North America, broadening our lines of services
and products, and adding density and operating leverage within our current
markets. Management believes that the experience and industry reputations of the
senior managers of the operating companies and senior corporate management of
RailWorks provide RailWorks with a competitive advantage in identifying,
completing and integrating acquisitions. Since we completed our IPO in August
1998, we have acquired 15 companies. We have entered into letters of intent to
acquire another four companies. We expect to execute definitive purchase
agreements with one exception, which will have customary closing conditions,
including completion of due diligence, prior to the end of 1999. However, we
cannot guarantee that we will consummate any of these acquisitions. Our
acquisition strategy includes the following elements:


     - Enter New Geographic Markets.  Management intends to expand into
       geographic markets that we do not currently serve by acquiring
       well-established contractors and related supply companies that are
       leaders in their regional or local markets. In addition, after an initial
       emphasis on acquisitions within the United States and Canada, management
       may pursue international acquisition opportunities.

     - Enter Complementary Services and Product Markets.  Management intends to
       continue acquiring companies offering complementary services and products
       to those currently offered by the operating companies. Specifically,
       management believes that attractive acquisition opportunities will
       continue to exist with respect to design and engineering firms, designers
       and manufacturers of signaling and communication systems and suppliers of
       electrical equipment, rail, switches and panels, and concrete and steel
       ties.

                                       45
<PAGE>   51

     - Expand Within Existing Geographic Markets.  Management plans to acquire
       additional companies in many of the regions in which we currently operate
       in order to expand the volume and scope of our operations in a particular
       market. Management will continue to pursue acquisitions of smaller
       companies to increase utilization of our existing fixed assets and
       equipment or to gain access to new customers. Management believes these
       types of acquisitions will improve operating efficiencies and more
       effectively use our capital resources without a proportionate increase in
       administrative costs.

     Reduce Operating Costs.  Key areas in which management has achieved and
expects to continue to achieve cost savings include (1) purchasing of equipment
and supplies, (2) insurance expenses and (3) financing costs. We have also
established an operating platform to achieve optimal utilization of equipment,
inventory and our workforce. We expect to continue to reduce administrative
expenses through the integration of certain accounting, financing, human
resources and other functions.

SERVICES AND PRODUCTS

     We operate in three business lines: (1) transit services; (2) rail
construction services; and (3) rail products and supplies. The following chart
sets forth the percentage of 1998 pro forma revenue that was represented by each
business line.

                                    (CHART)

  Transit Services

     Our transit services business includes all products and services that we
provide to rail-based public transit agencies and authorities in various
metropolitan markets. We typically contract with these agencies to install (1)
electric train traction power systems by means of third rail or overhead
catenary wiring, (2) train control signal systems, (3) train, station and
command station communications systems, (4) general electrical installations for
lighting and other applications and (5) tunnel and station track. We can perform
major new projects that involve track installation including excavation,
grading, paving and drainage improvements as well as minor rehabilitation
projects. Projects for new public transit lines generally include the
installation of all of these systems, giving us a competitive advantage.

     In addition, we leverage our knowledge of transit systems to efficiently
provide mechanical services, including installations of heating and air
conditioning systems, ventilating and pump rooms, fan chambers, elevators and
escalators. We have experience with rubber tired vehicular people mover systems,
installing concrete guided trackway, power guide beam, central guidance rail,
walkway and handrails.

                                       46
<PAGE>   52

     The duration and size of our transit contracts vary greatly depending on
the scope of the project. Large scale transit projects have had a term of up to
four years and have a total contract size of up to $100 million. We have
performed installations for most of the country's transit authorities, including
those in Atlanta, Boston, Chicago, Los Angeles, New York, Philadelphia,
Portland, San Diego, San Francisco, St. Louis and Washington, D.C. We generally
perform our services as either a prime contractor directly to the transit
agencies or as a subcontractor to large civil engineering contractors or
equipment manufacturers. Transit authorities award contracts through competitive
bidding and award contracts on a fixed price basis, generally to the lowest
bidder. As a result, we focus our business to (1) provide accurate bid
estimating to both win contracts and ensure a profit and (2) monitor
construction costs to ensure that projects are completed on time and within
budget. Our bidding process is highly involved and draws on the expertise of
many individuals within RailWorks. We carefully consider a variety of factors,
including material prices, local labor rates and practices, our knowledge of the
work site and contracting practices of the transit authorities. We have a
rigorous project review process that continually monitors the incurred labor and
material costs against an initial plan to avoid overruns. We believe that these
methods provide us with a competitive advantage.

     As an outgrowth of our transit-related business, we also perform commercial
real estate electrical installations, primarily in the New York City
metropolitan area and industrial electrical installations throughout the United
States. We contract for these projects on an opportunistic basis, that is, when
we have resources available and can realize attractive returns. We do not intend
to grow our non-rail-related businesses beyond the current scope.

  Rail Construction Services

     Our rail construction services business consists of providing rail design,
construction and maintenance services to Class I and shortline railroads and
industrial companies with on-site rail infrastructure. Rail design is a highly
specialized discipline and there are a limited number of companies that can
provide these services. We utilize our rail design capabilities to facilitate
access to rail construction projects. By having the ability to provide
integrated design-build services, we have had success in increasing our project
flow. Our rail construction efforts primarily involve the construction of main
line segments, passing sidings, rail yards, connector segments between railroads
and industrial sites, turnouts and track and road intersections. With respect to
track maintenance, we enter into multi-year contracts with several customers to
provide ongoing maintenance of on-site rail infrastructure. Maintenance
contracts allow us to obtain recurring revenues and gain access to additional
new construction projects from the same customer. Additional rail contracting
services also include the removal of tracks which are no longer in use.

     Rail construction and maintenance are highly complex processes that usually
involve numerous separate parties that design, supply and construct the
different elements of the track. Following the design stage, construction
entails (1) site preparation and grading, (2) the laying of ballast (gravel) to
provide a solid track fixation medium, (3) the positioning of cross ties, (4)
securing rail with high precision using metal plates, spikes and clamps, (5)
installing complex track crossings and turnouts and (6) installing other track
related systems such as signal, communications and automatic train control and
safety devices. Management believes that our ability to bundle these services on
a turnkey basis provides RailWorks with a significant competitive advantage.

     We provide our rail services on a nationwide basis. Since it is generally
not economical to work on contracts outside of a 300 mile radius of an operating
facility, this broad footprint facilitates servicing customers with multiple
sites across regions. Most of our competitors in this market are regionally
focused. Management believes RailWorks has a competitive advantage due to its
ability to direct equipment and labor resources to regions with higher demand
due to economic or seasonal fluctuations. We also maintain track and track
material inventory at each
                                       47
<PAGE>   53

location. By coordinating information across our network we can maximize
inventory utilization and improve supply for projects in different regions.

  Rail Products and Supplies

     We manufacture wooden and concrete products and rail fastening systems out
of four facilities. Our wooden products include cross ties and switch and bridge
timbers. Our wood treating operations consist of pressure-treating pre-cut beams
of hardwood to provide weather-proofing. These treated cross ties are used for
securing rail for tracks or assembled to construct bridge support structures.
Concrete products consist primarily of pre-cast structural components for
bridges and other support structures. Our concrete operations consist of pouring
mixed concrete into large molds to create specialized structural support
components. We also design and manufacture rail fastening systems, which are
primarily used in overhead and portal crane rail applications.

     Our rail construction operations source rail and other track materials
(primarily metal components such as plates and spikes) from (1) the reclamation
of existing track that is no longer in use, (2) track materials brokers and (3)
manufacturers. We sell our rail products and supplies directly to contractors,
including our own subsidiaries, and to Class I and shortline railroads that
perform their own track construction and maintenance. Some of our products are
used in non-rail applications such as highway construction and decorative
landscaping.

     Our product capabilities provide us with an advantage in supplying our
track construction and maintenance operations. This is particularly important in
the context of wooden cross ties as the market has experienced shortages in the
past. There are a limited number of cross tie manufacturing facilities in North
America due to stringent regulations. We enhance our competitive advantage by
having uninterrupted access to cross ties and other track products. We have also
developed strong customer relationships through products sales, particularly
with Class I and shortline railroads. Additionally, we lease track construction
and maintenance equipment. By offering operating leases for such equipment, we
have formed additional industry relationships, created an additional revenue
source and established an avenue to fully utilize the operating life of our
equipment. As part of our growth strategy, we intend to leverage these
relationships to cross-sell other services, particularly design and engineering
as well as track construction and maintenance.

ACQUISITION PROGRAM

     Management believes the combination of management's acquisition expertise
and the highly fragmented nature of the rail services and products industry
provides RailWorks with significant acquisition opportunities. RailWorks
identifies acquisition candidates by leveraging the relationships of its
experienced operational managers and utilizing its dedicated acquisitions team.
We focus on acquiring companies that have a strategic fit, provide us with cost
synergies, complement our geographic presence, and demonstrate a willingness to
learn and share best practices through open communications. After an initial
screening, management evaluates each acquisition candidate through its due
diligence process, which includes detailed financial and operational reviews.
During the due diligence process, we often identify a number of areas in which
we expect to realize efficiencies during the integration process. We offer
acquisition candidates several benefits, including:

     - expertise to expand in specialized markets;

     - enhanced productivity through the reduction of administrative burdens;

     - national name recognition;

     - increased bonding capacity;

                                       48
<PAGE>   54

     - access to public capital markets; and

     - the opportunity for a continued role in management.

Other key elements of our acquisition program include:

     Retain and Provide Incentives to Existing Management.  We seek acquisitions
of successful companies whose senior managers will remain as employees of
RailWorks and continue to operate their respective businesses on a local level.
We motivate these managers and align their interests with those of RailWorks
through (1) employment agreements, (2) shares of common stock as a portion of
the acquisition consideration and (3) a structured earnout program which is tied
to the acquired entity meeting specific earnings targets.

     Leverage Industry Reputation and Contacts.  We utilize existing industry
relationships established by the operating companies and RailWorks management to
develop a broad base of potential acquisitions. We intend to remain actively
involved in industry organizations on local and national levels, working with
independent companies to support issues of interest to RailWorks.

     Acquisition Consideration.  In the course of implementing our acquisition
strategy, we have typically used cash and performance-based earnouts as
consideration for the acquired businesses. In the future, we expect to use a
combination of cash, common stock, promissory notes and performance-based
earnouts as consideration for acquired businesses. See "Risk Factors -- Risks
Relating to the Company -- We May Be Unable to Complete and Finance
Acquisitions".

- ---------------

(1) Railworks acquired certain assets and ongoing contracts of Sheldon Electric
    Co., Inc. Therefore, only revenue since the date of acquisition ($1.4
    million since November 4, 1998) has been included above.

(2) Pandrol Jackson, Inc., a Delaware corporation, was in the business of, among
    other things, manufacturing and selling switch and crossing grinders and
    providing related services. On January 30, 1998, Harsco Corporation, a
    Delaware corporation, and Harsco Technologies Corporation, a Minnesota
    corporation, agreed to purchase certain assets of Pandrol Jackson, Inc. and
    Pandrol Jackson Limited, a corporation incorporated under the laws of
    England. RailWorks acquired from Harsco only those assets previously owned
    by Pandrol Jackson, Inc. relating to manufacturing and selling switch and
    crossing grinders and providing related services.


SOURCES OF SUPPLY

     We purchase new rail from a limited number of suppliers. New rail is
generally installed only on main lines, where the track may carry high volumes
of heavy traffic at high speeds. Over time, rail is removed, inspected and, if
in the appropriate condition, refurbished for sale as "relay" rail. Relay rail
is typically installed on secondary -- non-main line -- tracks, as well as yard
or branch tracks. Total rail life before scrapping may be as long as 60 years.
We also purchase a large volume of relay rail that third parties refurbish and
resell.

     Similarly, we regularly purchase entire sections of track that we remove
and subsequently disassemble at our facilities. We inspect the various track
components -- rail, ties, and accessories -- and items are placed into our
inventory, either in their "as removed" condition or after being refurbished by
third parties, or sold for scrap. Additionally, in connection with certain
repair and rehabilitation projects, we acquire removed trackwork. Management
believes the RailWorks network of contractors enables it to acquire previously
used track on comparatively advantageous terms.

     For installing electrical signaling and communication systems for transit
authorities, we purchase equipment from a limited number of suppliers. See "Risk
Factors -- Risks Relating to the Company -- We Rely on Subcontractors and
Suppliers".

     Certain of our operating companies process creosote-treated wooden ties.
Their operations include the purchase of raw lumber, trimming the lumber to
specified sizes, pressurized impregnation of the lumber with creosote
preservative and finishing of the ties, which would

                                       50
<PAGE>   56

include the pre-drilling of spike holes and the attachment of plates, as
specified by the customer. The service life of pressure treated ties has been
extended to a range of 25 to 40 years.

     Management believes RailWorks can purchase materials in sufficient
quantities to permit it to realize purchasing economies and discounts from its
suppliers. Historically, the cost of the lumber used to produce wooden ties,
steel used to produce rail, and copper used to produce electrical wiring has
fluctuated significantly due to market and industry conditions. Increasing
demand for these raw materials may result in cost increases. We cannot guarantee
that we will be able to recoup any of those increases by increasing the prices
of our products. Further, a reduction in supply of lumber, steel or copper due
to increased demand or other factors could have an adverse effect on our
business, financial condition and results of operations.

SALES AND MARKETING

     We maintain a targeted national sales program to further develop the
business of each of the operating companies. This initiative focuses on the
Class I railroads and other large industrial companies with facilities in
multiple areas. Prior to their acquisition by RailWorks, the individual
operating companies had been unable to serve such customers on a comprehensive,
nationwide basis. In addition, our ability to offer electrical installation
services together with rail construction, rehabilitation, repair and maintenance
services and related products provides us with opportunities to cross-sell our
services to large industrial companies. Management believes that RailWorks has
an advantage over its competitors since it can offer consistent, high-quality
service and products throughout the United States. Our expansive geographic
coverage enables customers to use our services and products in multiple
locations rather than dealing with numerous regional or local companies.

     We have achieved significant synergies in our marketing programs.
Management also believes that RailWorks has developed and will continue to
refine cross-selling programs under which:


          (1) our design and engineering groups provide timely leads to its
     construction, product supply and electrical installation companies,



          (2) our electrical signaling and communications companies, which have
     previously utilized third parties for track engineering and construction,
     utilize other operating companies for these projects, and



          (3) our track construction companies contract with other operating
     companies for signaling, communication and electrical installation
     services.


     Similarly, our product supply companies have, over the years, developed
long-term relationships with the Class I railroads and large industrial
companies, and management believes that these relationships provide an
attractive basis for marketing our construction and maintenance services.

BIDDING AND CONTRACTS

     A majority of our pro forma revenue for the year ended December 31, 1998
was derived from contracts entered into through a competitive bidding process.
Public agencies, including the NYCTA, that solicit bids are generally required
to accept the lowest cost proposal. In some cases, the party that submitted the
low bid must first pass a technical qualification before being awarded a
project. Following the acceptance of a bid, we typically enter into a contract
with the customer. Our track construction and repair projects generally do not
involve long-term contracts.

     Many projects that are competitively bid require the company that is
awarded the project to post a bond, which varies according to the size of the
project. Each company has a bonding limit, which is based on the company's
working capital and work in progress. The bond provides the customer with
insurance in the event that the company is unable to complete the project.
Accordingly, the ability of each of the operating companies to bid on larger
projects had, prior to
                                       51
<PAGE>   57

their acquisition by RailWorks, had been limited by their ability to obtain the
required bonding. The size of RailWorks, as compared to the size of the
individual operating companies, facilitated increases in the bonding limits for
each operating company thereby better positioning them to bid on and undertake
significantly larger construction and maintenance projects. Management believes
that the increased bonding capacity permits us to bid on and undertake more
projects than could smaller companies. See "Risk Factors -- Risks Relating to
RailWorks -- Our Fixed Price Contracts Expose us to Significant Risks".

COMPETITION

     The rail system services and products industry is competitive, and projects
are often awarded through competitive bidding. We compete with other rail system
construction, rehabilitation and maintenance companies, electrical contractors
and suppliers of products. Certain competitors have significantly greater
resources than we have, may provide a broad range of services and products, and
may have sufficient bonding capacity to undertake large projects. We compete on
the basis of our breadth of services and products, ability to take on large
projects and nationwide presence. Any inability of RailWorks to compete
successfully against existing and future competitors would have a material
adverse effect on our business, results of operations and financial condition.
Moreover, we may depend in part upon opportunities for consolidation in the rail
system services and products industry in order to execute effectively our
acquisition and vertical integration strategy. If our customers do not receive
our vertical integration strategy favorably, these customers have numerous
alternative sources of services and supply.

RISK MANAGEMENT AND SAFETY

     Because our business is labor intensive, workers' compensation is a
significant operating expense for us. We could be exposed to liability for the
acts or negligence of its employees who cause personal injury or damage while on
assignment, as well as claims of misuse of customer proprietary information or
theft of client property. We have adopted policies and procedures intended to
reduce our exposure to these risks.

     We maintain insurance against these risks with policy limits we consider
sufficient and consistent with industry standards. We have retained a risk
management professional who is responsible for claims management and the
establishment of appropriate reserves for the deductible portion of claims. We
hold regular meetings with the presidents of the operating companies at which
safety issues are discussed. We also conduct routine safety inspections of local
work sites.
                                       52
<PAGE>   58

EQUIPMENT AND FACILITIES

     We own and maintain specialized equipment used in rail construction,
rehabilitation, repair and maintenance. This equipment may be moved between job
sites and, consequently, we are seeking to increase the sharing of equipment
between the operating companies where it is appropriate and cost effective. For
example, during the winter months, the operating companies located in the
northern United States could relocate their equipment to the operating companies
located in the South. Each of the operating companies generally performs its own
equipment maintenance. We intend to manage our equipment through our equipment
leasing subsidiary, which will maintain a comprehensive database that tracks the
use of all of our equipment.


     Our corporate offices are in approximately 3,000 square feet of leased
space in a suburb of Baltimore, Maryland. In addition to our corporate offices,
we lease 38 and own 12 operating facilities. These facilities consist of local
offices, storage yards, distribution facilities, warehouses and wood processing
plants.


GOVERNMENT REGULATION

     Overview.  In addition to the environmental, safety and other regulations
generally applicable to all businesses, regulations that are administered by the
Surface Transportation Board, the successor to the Interstate Commerce
Commission ("ICC"), the FRA and by regulatory agencies impact our business in
the various states where we and our customers do business. Since 1980, there has
been a significant relaxation in regulations governing the sale, leasing or
other transfer of railroad properties, and this change has favorably affected
the operations of many of our customers. Various interests in the United States
have sought and continue to seek reimposition of government controls on the
railroad industry in areas deregulated in whole or in part since 1980, including
stricter rate regulation and more onerous labor protection conditions for rail
line transfers.

     Railroad Regulations.  The ICC Termination Act, enacted on December 29,
1995, eliminated the ICC as an independent agency and created the STB, a new
agency within the Department of Transportation which began functioning on
January 1, 1996. The ICC Termination Act changed the procedure and timing for
federal approval of rail projects, including abandonments, line sales, mergers,
rates and tariffs, simplifying and streamlining the abandonment process. The FRA
regulates railroad safety and equipment standards, including track maintenance
and train speed standards, special procedures for handling hazardous shipments,
locomotive and railcar inspection and repair requirements, operating practices
and crew qualifications. The Roadway Worker Protection Rules, promulgated by the
FRA, apply to rail contractors and establish certain safety criteria that must
be complied with on rail projects.

     TEA 21.  On June 9, 1998, the President signed TEA 21, the six-year surface
transportation program that represents a significant development in the federal
transit program. TEA 21, the largest infrastructure funding bill in U.S.
history, authorizes funding for transit in the amount of $42 billion through
2003. TEA 21 authorizes over 50 percent more than the 1991 Intermodal Surface
Transportation Efficiency Act, whose funding has expired.

     State Regulatory Agencies.  State regulatory agencies no longer have
authority to engage in economic regulation of railroads that are part of the
intrastate network. State and local governments generally retain jurisdiction
over local rail safety matters, such as the installation of grade crossings and
grade crossing warnings devices.

ENVIRONMENTAL MATTERS

     Our operations and properties are subject to environmental laws and
regulations relating to pollution and protection of the environment and public
and employee health and safety. The principal environmental regulatory
requirements applicable to our operations relate to the use of

                                       53
<PAGE>   59

creosote to treat lumber, and the generation, storage, transportation, treatment
and disposal of solid and hazardous wastes. We believe that our operations have
all required environmental permits and currently comply, in all material
respects, with applicable regulatory requirements.

     We have had environmental assessments performed for recent acquisitions.
Based on these reports and available information, we are not aware of any
significant environmental exposures or claims against us. However, the
historical and current uses of our facilities may have resulted in spills or
releases of various hazardous materials, which now, or in the future, could
require remediation. We also may be subject to requirements related to
remediation of hazardous materials that have been released into the environment
at properties that we own or operate, or that we owned or operated in the past
or at properties to which we send, or may have sent, hazardous materials for
treatment or disposal. Such remediation requirements generally are imposed
without regard to fault, and liability for any required environmental
remediation can be substantial.

EMPLOYEES


     As of September 30, 1999, we employed approximately 2,900 employees. We
believe that we have good relations with our employees.



     Approximately 50% of our employees are members of certain labor unions and
are employed pursuant to collective bargaining agreements. Some of the operating
companies are parties to collective bargaining agreements with the International
Brotherhood of Electrical Workers, Laborers' International Union of North
America, the International Union of Operating Engineers, United Brotherhood of
Carpenters and Joiners of America and the United Brotherhood of Teamsters. Some
of our customers hire only unionized labor. Our largest collective bargaining
agreement, covering 1,054 employees, expires in June 2001. Except for a one-week
work stoppage in Connecticut by the United Brotherhood of Teamsters in June
1994, we have not experienced any work stoppages in the past five years.


INFORMATION TECHNOLOGY SYSTEMS


     We are in the process of implementing integrated information technology
systems that will be utilized by each of the operating companies. These
information technology systems will be used for a variety of purposes, including
monitoring inventory levels, tracking the progress of construction projects and
integrating our financial, general ledger, payables and receivables functions.
In addition, we will network our corporate offices to the offices of our
operating companies and will have e-mail capability at all offices. We expect
that the required systems will be purchased and installed by the end of 1999 and
that our expenditures for these systems will not be material to us. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources." All of the new systems will be
Year 2000 compatible. Until these new systems are fully operational, each of the
operating companies will continue using the information systems that they
currently use.


LEGAL PROCEEDINGS

     From time to time, we may be involved in routine legal proceedings
incidental to the conduct of our business. In the opinion of management, the
litigation, individually or in the aggregate, to which we are currently a party,
is not likely to have a material adverse effect on our business, financial
condition and results of operations.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     We sold the old notes on September 30, 1999 to First Union Capital Markets
pursuant to a purchase agreement. The initial purchaser subsequently sold the
old notes to:

     - "qualified institutional buyers" ("QIBs"), as defined in Rule 144A under
       the Securities Act, in reliance on Rule 144A, and to

     - persons in offshore transactions in reliance on Regulation S under the
       Securities Act.

     As a condition to the initial sale of the old notes, RailWorks and the
initial purchaser entered into a registration rights agreement. Pursuant to the
registration rights agreement, we agreed to

     - file a registration statement under the Securities Act with respect to
       the exchange notes with the SEC by November 13, 1999 and


     - use our reasonable best efforts to cause the registration statement to
       become effective under the Securities Act on or before January 28, 2000.


     We agreed to issue and exchange the new notes for all old notes validly
tendered and not validly withdrawn prior to the expiration of the exchange
offer. A copy of the registration rights agreement has been filed as an exhibit
to the registration statement, which includes this prospectus. The registration
statement is intended to satisfy some of our obligations under the registration
rights agreement and the purchase agreement.

     The term "holder" with respect to the exchange offer means any person in
whose name old notes are registered on the trustee's books or any other person
who has obtained a properly completed bond power from the registered holder, or
any person whose old notes are held of record by The Depository Trust Company
(the "Depositary" or "DTC") who desires to deliver such old note, by book-entry
transfer at DTC.

RESALE OF THE NEW NOTES

     We believe that you will be allowed to resell the new notes to the public
without registration under the Securities Act, and without delivering a
prospectus that satisfies the requirements of Section 10 of the Securities Act
if you can make the representations set forth above under "Prospectus
Summary -- The Exchange Offer -- Procedures for participating in the exchange
offer." However, if you intend to participate in a distribution of the new
notes, or you are an "affiliate" of RailWorks as defined under Rule 405 of the
Securities Act, you must comply with the registration requirements of the
Securities Act and deliver a prospectus, unless an exemption from registration
is otherwise available. You have to represent to RailWorks in the letter of
transmittal accompanying this prospectus that you meet these conditions
exempting you from the registration requirements.

     We base our view on interpretations by the staff of the SEC in no-action
letters issued to other issuers in exchange offers like ours. However, we have
not asked the SEC to consider this particular exchange offer in the context of a
no-action letter. Therefore, you cannot be sure that the SEC will treat it in
the same way it has treated other exchange offers in the past.

     A broker-dealer that has bought old notes for market-making or other
trading activities has to deliver a prospectus in order to resell any old notes
it has received for its own account in the exchange. This prospectus may be used
by a broker-dealer to resell any of its old notes. We have agreed in the
registration rights agreement to send this prospectus to any broker-dealer that
requests copies in the letter of transmittal for a period of up to 180 days
after the SEC declares the registration statement relating to this exchange
offer effective. See "Plan of Distribution" for more information regarding
broker-dealers.

                                       55
<PAGE>   61

     The exchange offer is not being made to, nor will we accept surrenders for
exchange from, holders of old notes in any jurisdiction in which this exchange
offer or the acceptance thereof would not be in compliance with the securities
or blue sky laws.

TERMS OF THE EXCHANGE OFFER

     General.  Based on the terms and conditions set forth in this prospectus
and in the letter of transmittal, we will accept any and all old notes validly
tendered and not validly withdrawn prior to 5:00 p.m., New York City time, on
the expiration date.

     Subject to the minimum denomination requirements of the new notes, we will
issue $1,000 principal amount of new notes in exchange for each $1,000 principal
amount of outstanding old notes validly tendered pursuant to the exchange offer
and not validly withdrawn prior to the expiration date. Holders may tender some
or all of their old notes pursuant to the exchange offer. However, old notes may
be tendered only in amounts that are integral multiples of $1,000 principal
amount.

     The form and terms of the new notes are the same as the form and terms of
the old notes except that:

     - the new notes will be registered under the Securities Act and, therefore,
       the new notes will not bear legends restricting the transfer the new
       notes,

     - the new notes shall not contain provisions for additional interest and

     - holders of the new notes will not be entitled to any of the registration
       rights of holders of old notes under the registration rights agreement,
       which rights will terminate upon the consummation of the exchange offer.

     The new notes will evidence the same indebtedness as the old notes, which
they replace, and the existing notes. The new notes will be issued under, and be
entitled to the benefits of, the same indenture that authorized the issuance of
the old notes and the existing notes. As a result, both the new notes, the old
notes and the existing notes will be treated as a single class of debt
securities under the indenture. The exchange offer does not depend upon any
minimum aggregate principal amount of old notes being surrendered for exchange.


     As of the date of this prospectus, $50,000,000 in aggregate principal
amount of the old notes is outstanding, all of which is registered in the name
of Cede & Co., as nominee for DTC. Solely for reasons of administration, we have
fixed the close of business on December 14, 1999 as the record date for the
exchange offer for purposes of determining the persons to whom this prospectus
and the letter of transmittal will be initially mailed. There will be no fixed
record date for determining holders of the old notes entitled to participate in
this exchange offer.


     As a holder of old notes, you do not have any appraisal or dissenters'
rights, or any other right to seek monetary damages in court under the Delaware
General Corporation Law or the indenture governing the notes. We intend to
conduct the exchange offer in accordance with the provisions of the registration
rights agreement and the applicable requirements of the Exchange Act and the
related rules and regulations of the SEC. Old notes that are not surrendered for
exchange in the exchange offer will remain outstanding and interest thereon will
continue to accrue.

     We will be deemed to have accepted validly surrendered old notes if and
when we give oral or written notice of our acceptance to the exchange agent. The
exchange agent will act as agent for the tendering holders of old notes for the
purpose of receiving the new notes from us.

     If you surrender old notes in the exchange offer, you will not be required
to pay brokerage commissions or fees. In addition, subject to the instructions
in the letter of transmittal, you will not have to pay transfer taxes for the
exchange of old notes. We will pay all charges and expenses

                                       56
<PAGE>   62

in connection with the exchange offer, other than certain applicable taxes
described under "--Fees and Expenses."

EXPIRATION DATE; EXTENSIONS; AMENDMENTS


     The "expiration date" is 5:00 p.m., New York City time, on January 21,
2000, unless we extend the exchange offer, in which case the expiration date is
the latest date and time to which we extend the exchange offer.


     In order to extend the exchange offer, we will:

     - notify the exchange agent of any extension by oral or written
       communication;

     - issue a press release or other public announcement, which will report the
       approximate number of old notes deposited; such press release or
       announcement would be issued prior to 9:00 a.m., New York City time, on
       the next business day after the previously scheduled expiration date.
       During any extension of the exchange offer, all old notes previously
       surrendered and not withdrawn will remain subject to the exchange offer.

     We reserve the right:

     - to delay accepting any old notes,

     - to amend the terms of the exchange offer in any manner,

     - to extend the exchange offer, or

     - if, in the opinion of our counsel, the consummation of the exchange offer
       would violate any law or interpretation of the staff of the SEC, to
       terminate or amend the exchange offer by giving oral or written notice to
       the exchange agent.

     Any delay in acceptance, extension, termination or amendment will be
followed as soon as practicable by a press release or other public announcement.
If we amend the exchange offer in a manner that we determine constitutes a
material change, we will promptly disclose that amendment by means of a
prospectus supplement that will be distributed to the holders, and we will
extend the exchange offer for a period of time, depending upon the significance
of the amendment and the manner of disclosure to the holders, if the exchange
offer would otherwise expire during that period.

     We will have no obligation to publish, advertise, or otherwise communicate
any public announcement that we may choose to make, other than by making a
timely release to an appropriate news agency.

     In all cases, issuance of the new notes for old notes that are accepted for
exchange will be made only after timely receipt by the exchange agent of a
properly completed and duly executed letter of transmittal and all other
required documents. However, we reserve the absolute right to waive any
conditions of the exchange offer or any defects or irregularities in the
surrender of old notes. If we do not accept any surrendered old notes for any
reason set forth in the terms and conditions of the exchange offer or if you
submit old notes for a greater principal amount than you want to exchange, we
will return certificates for the unaccepted or non-exchanged old notes, or
substitute old notes evidencing the unaccepted portion, as appropriate, to you.
See "-- Return of Old Notes."

INTEREST ON THE NEW NOTES

     The new notes will accrue cash interest on the same terms as the old notes,
i.e., at the rate of 11 1/2% per year (using a 360-day year) from September 30,
1999, payable semi-annually in arrears on April 15 and October 15 of each year,
beginning on October 15, 1999. Old notes accepted for exchange will not receive
accrued interest thereon at the time of exchange.

                                       57
<PAGE>   63

However, each new note will bear interest from the most recent date to which
interest has been paid on the old notes or new notes, or if no interest has been
paid on the old notes or new notes, from September 30, 1999.

PROCEDURES FOR TENDERING OLD NOTES

     If you wish to surrender old notes you must:

     - complete and sign the letter of transmittal or a facsimile thereof,

     - have the signatures thereon guaranteed if required by the letter of
       transmittal, and

     - mail or deliver the letter of transmittal or facsimile, together with any
       corresponding certificate or certificates representing the old notes
       being surrendered -- or confirmation of a book-entry transfer of such old
       notes into the exchange agent's account at DTC pursuant to the book-entry
       procedures described below -- to the exchange agent at its address set
       forth in the letter of transmittal for receipt prior to the expiration
       date. If the certificate representing the old notes being tendered -- or
       the confirmation of a book-entry transfer, if applicable -- is not
       delivered to the exchange agent with the letter of transmittal, you must
       comply with the guaranteed delivery procedures described below. DELIVERY
       OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH ITS
       PROCEDURE DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

     If you do not withdraw your surrender of old notes prior to the expiration
date, it will indicate an agreement between you and RailWorks that you have
agreed to surrender the old notes, in accordance with the terms and conditions
in the letter of transmittal.

     THE METHOD OF DELIVERY OF OLD NOTES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT YOUR ELECTION AND RISK.
INSTEAD OF DELIVERY BY MAIL, YOU SHOULD USE AN OVERNIGHT OR HAND DELIVERY
SERVICE, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED. IN ALL CASES, YOU
SHOULD ALLOW SUFFICIENT TIME TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE
EXPIRATION DATE. DO NOT SEND ANY LETTER OF TRANSMITTAL OR OLD NOTES TO US. YOU
MAY REQUEST THAT YOUR BROKER, DEALER, COMMERCIAL BANK, TRUST COMPANY OR NOMINEE
EFFECT THE ABOVE TRANSACTIONS FOR YOU.

     If you are a beneficial owner of the old notes and your old notes and hold
those notes through a broker, dealer, commercial bank, trust company or other
nominee and you want to surrender your old notes, you should contact that
intermediary promptly and instruct it to surrender the old notes on your behalf.

     Generally, an eligible institution must guarantee signatures on a letter of
transmittal or a notice of withdrawal described below under "-- Withdrawal of
Tenders of Old Notes" unless

     - you tender your old notes as the registered holder, which term includes
       any participant in DTC whose name appears on a security listing as the
       owner of old notes,

     - you sign the letter of transmittal, and the new notes issued in exchange
       for your old notes to be issued in your name, or

     - you surrender your old notes for the account of an eligible institution.

     In any other case, the surrendered old notes must be endorsed or
accompanied by written instruments of transfer in form satisfactory to us and
duly executed by the registered holder. If the new notes or unexchanged old
notes are to be delivered to an address other than that of the registered holder
appearing on the security register for the old notes, an eligible institution
must guarantee the signature in the letter of transmittal. In the event that
signatures on a letter of

                                       58
<PAGE>   64

transmittal or a notice of withdrawal are required to be guaranteed, such
guarantee must be made by:

     - a member firm of a registered national securities exchange or of the
       National Association of Securities Dealers, Inc.,

     - a commercial bank or trust company having an office or correspondent in
       the United States, or an "eligible guarantor institution" as defined by
       Rule 17Ad-15 under the Exchange Act that is a member of one of the
       recognized signature guarantee programs identified in the letter of
       transmittal.

     Your surrender will be deemed to have been received as of the date when:

     - the exchange agent receives a properly completed and signed letter of
       transmittal accompanied by the old notes, or a confirmation of book-entry
       transfer of such old notes into the exchange agent's account at DTC, or

     - the exchange agent receives a notice of guaranteed delivery from an
       eligible institution. Issuances of new notes in exchange for old notes
       surrendered pursuant to a notice of guaranteed delivery or letter,
       telegram or facsimile transmission to similar effect by an eligible
       institution will be made only against submission of a duly signed letter
       of transmittal, and any other required documents, and deposit of the
       surrendered old notes, or confirmation of a book-entry transfer of such
       old notes into the exchange agent's account at DTC pursuant to the
       book-entry procedures described below.

     We will make the determination regarding all questions relating to the
validity, form, eligibility, including time of receipt, acceptance and
withdrawal of surrendered old notes, and our determination will be final and
binding on all parties.

     We reserve the absolute right to reject any and all old notes improperly
surrendered. We will not accept any old notes if our acceptance of them would,
in the opinion of our counsel, be unlawful. We also reserve the absolute right
to waive any defects, irregularities, or conditions of surrender as to any
particular old notes. Our interpretation of the terms and conditions of the
exchange offer, including the instructions in the letter of transmittal, will be
final and binding on all parties. Unless waived, you must cure any defects or
irregularities in connection with surrenders of old notes within the time we
will determine. Although we intend to notify holders of defects or
irregularities in connection with surrenders of old notes, neither we, the
exchange agent nor anyone else will incur any liability for failure to give such
notice. Surrenders of old notes will not be deemed to have been made until any
defects or irregularities have been cured or waived.

     We have no current plan to acquire any old notes that are not surrendered
in the exchange offer or to file a registration statement to permit resales of
any old notes that are not surrendered pursuant to the exchange offer. We
reserve the right in our sole discretion to purchase or make offers for any old
notes that remain outstanding after the expiration date. To the extent permitted
by law, we also reserve the right to purchase old notes in the open market, in
privately negotiated transactions or otherwise. The terms of any future
purchases or offers could differ from the terms of the exchange offer.

     Pursuant to the letter of transmittal, if you elect to surrender old notes
in exchange for new notes, you must exchange, assign and transfer the old notes
to us and irrevocably constitute and appoint the exchange agent as your true and
lawful agent and attorney-in-fact with respect to such surrendered old notes,
with full power of substitution, among other things, to cause the old notes to
be assigned, transferred and exchanged. By executing the letter of transmittal,
you make the representations and warranties set forth above under the heading
"Prospectus Summary -- The Exchange Offer -- Procedures for participating in the
exchange offer" to us. By executing the letter of transmittal you also promise
to, upon request, execute and deliver any additional

                                       59
<PAGE>   65

documents that we consider necessary to complete the transactions described in
the letter of transmittal.

     By surrendering old notes in the exchange offer, you will be telling us
that, among other things,

     - you have full power and authority to tender, sell, assign and transfer
       the old notes surrendered,

     - we will acquire good title to the old notes being surrendered, free and
       clear of all security interests, liens, restrictions, charges,
       encumbrances, conditional sale agreements or other obligations relating
       to their sale or transfer, and not subject to any adverse claim when we
       accept the old notes,

     - you are acquiring the new notes in the ordinary course of your business,

     - you are not engaging and do not intend to engage in a distribution of the
       new notes,

     - you have no arrangement or understanding with any person to participate
       in the distribution of the new notes,

     - you acknowledge and agree that if you are a broker-dealer registered
       under the Exchange Act or you are participating in the exchange offer for
       the purpose of distributing the new notes, you must comply with the
       registration and prospectus delivery requirements of the Securities Act
       in connection with a secondary resale of the new notes, and that you
       cannot rely on the position of the SEC's staff set forth in their
       no-action letters,

     - you understand that a secondary resale transaction described above and
       any resales of new notes obtained by you in exchange for old notes
       acquired by you directly from us should be covered by an effective
       registration statement containing the selling security holder information
       required by Item 507 or 508, as applicable, of Regulation S-K of the SEC,
       and

     - you are not an "affiliate", as defined in Rule 405 under the Securities
       Act, of RailWorks or any subsidiary guarantor, or, if you are an
       "affiliate," that you will comply with the registration and prospectus
       delivery requirements of the Securities Act to the extent applicable.

     If you are a broker-dealer and you will receive new notes for your own
account in exchange for old notes that were acquired as a result of
market-making activities or other trading activities, you will be required to
acknowledge in the letter of transmittal that you will deliver a prospectus in
connection with any resale of such old notes.

     Participation in the exchange offer is voluntary. You are urged to consult
your financial and tax advisors in making your decision on whether to
participate in the exchange offer.

RETURN OF OLD NOTES

     If any old notes are not accepted for any reason described here, or if old
notes are withdrawn or are submitted for a greater principal amount than you
want to exchange, the exchange agent will return those unaccepted or
non-exchanged old notes to the surrendering holder, or, in the case of old notes
surrendered by book-entry transfer, into the exchange agent's account at DTC,
unless otherwise provided in the letter of transmittal. The old notes will be
credited to an account maintained with DTC as promptly as practicable.

BOOK ENTRY TRANSFER

     The exchange agent will make a request to establish an account with respect
to the old notes at DTC for purposes of the exchange offer promptly after the
date of this prospectus. Any financial institution that is a participant in
DTC's system may make book-entry delivery of old

                                       60
<PAGE>   66

notes by causing DTC to transfer such old notes into the exchange agent's
account at DTC in accordance with DTC's procedures for transfer. However,
although delivery of old notes may be effected through book-entry transfer at
DTC, you have to deliver the letter of transmittal, or a facsimile thereof, with
any required signature guarantees and any other required documents to the
exchange agent at the address set forth in the letter of transmittal for its
receipt on or prior to the expiration date or pursuant to the guaranteed
delivery procedures described below.

GUARANTEED DELIVERY PROCEDURES

     If you wish to surrender your old notes and (1) your old notes are not
immediately available so that you can meet the expiration date deadline, (2) you
cannot deliver your old notes or other required documents to the exchange agent
prior to the expiration date, or (3) the procedure for book-entry transfer
cannot be completed on a timely basis, you may nonetheless participate in the
exchange offer if:

     - you surrender your notes through an eligible institution;

     - prior to the expiration date, the exchange agent receives from the
       eligible institution a properly completed and duly executed notice of
       guaranteed delivery substantially in the form provided by us, by
       telegram, telex, facsimile transmission, mail or hand delivery, showing
       the name and address of the holder, the name(s) in which the old notes
       are registered, the certificate number(s) of the old notes, if
       applicable, and the principal amount of old notes surrendered; the notice
       of guaranteed delivery must state that the surrender is being made by the
       notice of guaranteed delivery and guaranteeing that, within three Nasdaq
       National Market trading days after the expiration date, the letter of
       transmittal, or facsimile thereof, together with the certificate(s)
       representing such old notes, in proper form for transfer or a book-entry
       confirmation, and any other required documents, will be delivered by such
       eligible institution to the exchange agent, and

     - the properly executed letter of transmittal, as well as the
       certificate(s) representing all surrendered old notes, in proper form for
       transfer, or a book-entry confirmation, as the case may be, and all other
       documents required by the Letter of Transmittal are received by the
       exchange agent within three Nasdaq National Market trading days after the
       expiration date.

     Unless old notes are surrendered by the above-described method and
deposited with the exchange agent within the time period set forth above, we
may, at our option, reject the surrender. The exchange agent will send you a
notice of guaranteed delivery upon your request if you want to surrender your
old notes according to the guaranteed delivery procedures described above.

WITHDRAWAL OF TENDERS OF OLD NOTES

     Except as otherwise provided in this prospectus, you may withdraw your
surrender of old notes at any time prior to 5:00 p.m., New York City time, on
the expiration date.

     To withdraw a surrender of old notes in the exchange offer, the exchange
agent must receive a written or facsimile transmission notice of withdrawal at
its address set forth herein prior to 5:00 p.m., New York City time, on the
expiration date. Any notice of withdrawal must:

     - specify the name of the person having deposited the old notes to be
       withdrawn,

     - identify the old notes to be withdrawn, including the certificate number
       or numbers, if applicable, and principal amount of the old notes,

     - contain a statement that you are withdrawing your election to have such
       old notes exchanged,

                                       61
<PAGE>   67

     - be signed by the holder in the same manner as the original signature on
       the letter of transmittal by which the old notes were surrendered, and

     - specify the name in which any old notes are to be registered, if
       different from that of the person depositing the old notes. If old notes
       have been surrendered pursuant to the procedure for book-entry transfer,
       any notice of withdrawal must specify the name and number of the account
       at DTC.

     We, in our sole discretion, will make the final determination on all
questions regarding the validity, form, eligibility and time of receipt of
notices, and our determination shall bind all parties. Any old notes withdrawn
will be deemed not to have been validly surrendered for purposes of the exchange
offer and no new notes will be issued unless the old notes so withdrawn are
validly resurrendered. Properly withdrawn old notes may be resurrendered by
following one of the procedures described above under "-- Procedures for
Tendering Old Notes" at any time prior to the business day prior to the
expiration date. Any old notes that are not accepted for exchange will be
returned at no cost to the holder or, in the case of old notes surrendered by
book-entry transfer, into the exchange agent's account at DTC pursuant to the
book-entry transfer procedures described above, as soon as practicable after
withdrawal, rejection of surrender or termination of the exchange offer.

TERMINATION OF CERTAIN RIGHTS

     All registration rights under the registration rights agreement that
benefit the holders of the old notes will terminate when we consummate the
exchange offer. That includes all rights to receive additional interest in the
event of a registration default under the registration rights agreement. In any
event, we are under a continuing obligation, for a period of up to 180 days
after the SEC declares the registration statement effective, to keep the
registration statement effective and to provide copies of the latest version of
the prospectus to any broker-dealer that requests copies in the letter of
transmittal for use in a resale.

CONDITIONS OF THE EXCHANGE OFFER

     Notwithstanding any other term of the exchange offer, or any extension of
the exchange offer, we do not have to accept for exchange, or exchange new notes
for, any old notes, and we may terminate the exchange offer before acceptance of
the old notes, if:

          (1) any statute, rule or regulation has been enacted, or any action
     has been taken by any court or governmental authority that, in our
     reasonable judgment, seeks to or would prohibit, restrict or otherwise
     render consummation of the exchange offer illegal; or

          (2) any change, or any development that would cause a change, in our
     business or financial affairs has occurred that, in our sole judgment,
     might materially impair our ability to proceed with the exchange offer or a
     change that would materially impair the contemplated benefits to us of the
     exchange offer; or

          (3) a change occurs in the current interpretations by the staff of the
     SEC that, in our reasonable judgment, might materially impair our ability
     to proceed with the exchange offer.

     If we, in our sole discretion, determine that any of the above conditions
is not satisfied, we may:

     - refuse to accept any old notes and return all surrendered old notes to
       the surrendering holders,

     - extend the exchange offer and retain all old notes surrendered prior to
       the expiration date, subject to the holders' right to withdraw the
       surrender of the old notes, or

                                       62
<PAGE>   68

     - waive any unsatisfied conditions regarding the exchange offer and accept
       all properly surrendered old notes that have not been withdrawn. If this
       waiver constitutes a material change to the exchange offer, we will
       promptly disclose the waiver by means of a prospectus supplement that
       will be distributed to the registered holders, and we will extend the
       exchange offer for a period of time that we will determine, depending
       upon the significance of the waiver and the manner of disclosure to the
       registered holders, if the exchange offer would otherwise expire during
       that period of time.

FEES AND EXPENSES

     We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, additional solicitation may be made by telecopy,
telephone or in person by our officers and regular employees or by officers and
employees of our affiliates. No additional compensation will be paid to any such
officers and employees who engage in soliciting tenders.

     We have not retained any dealer-manager or other soliciting agent for the
exchange offer and will not make any payments to brokers, dealers or others
soliciting acceptance of the exchange offer. We will, however, pay the exchange
agent reasonable and customary fees for its services and will reimburse it for
related, reasonable out-of-pocket expenses. We may also reimburse brokerage
houses and other custodians, nominees and fiduciaries for reasonable
out-of-pocket expenses they incur in forwarding copies of this prospectus, the
letter of transmittal and related documents.

     We will pay any expenses you will incur in connection with the exchange
offer, including registration fees, fees and expenses of the exchange agent, the
transfer agent and registrar, accounting and legal fees and printing costs,
among others.

     We will pay all transfer taxes, if any, applicable to the exchange of the
old notes. If, however, new notes, or old notes for principal amounts not
surrendered or accepted for exchange, are to be delivered to, or are to be
issued in the name of, any person other than the registered holder of the old
notes surrendered, or if a transfer tax is imposed for any reason other than the

                                       63
<PAGE>   69

exchange, then the amount of any transfer taxes will be payable by the person
surrendering the notes. If you do not submit satisfactory evidence of payment of
such taxes or exemption with the letter of transmittal, the amount of those
transfer taxes will be billed directly to you.

CONSEQUENCES OF FAILURE TO EXCHANGE

     Old notes that are not exchanged will remain "restricted securities" within
the meaning of Rule 144(a)(3) of the Securities Act. Accordingly, they may not
be offered, sold, pledged or otherwise transferred except:

     - to us or to any of our subsidiaries, inside the United States to a
       qualified institutional buyer in compliance with Rule 144A,

     - inside the United States to an institutional accredited investor that,
       prior to such transfer, furnishes to the trustee a signed letter
       containing certain representations and agreements relating to the
       restrictions on transfer of the old notes, the form of which you can
       obtain from the trustee and, if such transfer is in respect of an
       aggregate principal amount of old notes at the time of transfer of less
       than $100,000, an opinion of counsel acceptable to us that the transfer
       complies with the Securities Act,

     - outside the United States in compliance with Rule 904 under the
       Securities Act,

     - pursuant to the exemption from registration provided by Rule 144 under
       the Securities Act, if available, or

     - pursuant to an effective registration statement under the Securities Act.

     The liquidity of the old notes could be adversely affected by the exchange
offer.

ACCOUNTING TREATMENT

     For accounting purposes, we will recognize no gain or loss as a result of
the exchange offer. We will amortize the expenses of the exchange offer and the
unamortized expenses related to the issuance of the old notes over the remaining
term of the notes.

EMPLOYMENT AGREEMENTS

     RailWorks has employment agreements with each of Messrs. Larkin, Azarela
and Kennedy. The agreements expire on December 31, 2001, that date is the
"Expiration Date", and will continue on a year-to-year basis, unless terminated
by either party. Each agreement is terminable by RailWorks with or without cause
or upon the employee's death or inability to perform his duties on account of a
disability for a period of six months during any consecutive 12 month period or
by the employee. The agreements provide for annual base salaries of $325,000,
$275,000 and $100,000 for Messrs. Larkin, Azarela and Kennedy, respectively, and
provide that these executive officers will receive 5%, 2% and 1.5% respectively,
of RailWorks's first bonus pool, called the "First Bonus Pool", and 33.3%, 13.3%
and 10.0%, respectively, of RailWorks's second bonus pool, called the "Second
Bonus Pool". The First Bonus Pool consists of 10% of RailWorks's pre-tax
profits, and the Second Bonus Pool consists of 15% of the amount by which
RailWorks's net income exceeds certain benchmarks. In addition, the agreements
provided for the grant of shares of restricted stock and options to purchase
common stock, as described under the heading "-- Executive Compensation." The
agreements provide further that the employee may request a loan from RailWorks
in the amount of the income taxes due on stock granted to the employee under his
employment agreement. These loans are collateralized only by the stock granted
and the employee otherwise has no personal obligation to repay the loan. The
term of

                                       68
<PAGE>   74

these loans are five years, requiring annual interest payments; however, the
term is accelerated following termination of employment. Each agreement also
contains noncompetition, nonsolicitation and confidential information
provisions.

     RailWorks also has an employment agreement with Mr. Burk. The agreement
expires on May 10, 2002 and will continue on a year-to-year basis, unless
terminated by either party. The agreement is terminable by RailWorks with or
without cause or upon the employee's death or inability to perform his duties on
account of a disability for a period of six months during any consecutive
twelve-month period, or by the employee. The agreement provides for an annual
base salary of $275,000 and provides that he will receive, as a bonus for each
fiscal year during which the agreement is in force, .3% of the net income of
RailWorks before income taxes and bonuses (or, for the year ending December 31,
1999, $100,000, if .3% of such net income is less than $100,000), and for the
grant of options to purchase common stock. The agreement also contains
noncompetition, nonsolicitation and confidential information provisions.

     RailWorks has also entered into employment agreements with the key
employees and certain employees of each Founding Company and Acquired Company.
The agreements generally expire on the second anniversary of the closing of the
Company's acquisition of the employee's company. On and after such date, the
agreements automatically renew for successive one-year terms until either party
gives 90 days written notice of termination of the agreement, each termination
date is called the "Expiration Date". Each agreement is terminable by RailWorks
with or without cause or upon the employee's death or inability to perform his
duties on account of a disability for a period of six months during any
consecutive 12-month period or by the employee. Each agreement provides for an
annual base salary and provides that the salary will be adjusted after the
initial term of the agreement to reflect the employee's duties and
responsibilities. Further, each employee is entitled to a portion of the First
Bonus Pool and the Second Bonus Pool. As a group, the owners of the Founding
Companies and Acquired Companies are entitled to an aggregate of 40% of the
First Bonus Pool and 33.3% of the Second Bonus Pool.

1998 STOCK INCENTIVE PLAN


     The RailWorks board of directors has adopted, and the RailWorks
stockholders have approved, the RailWorks 1998 Stock Incentive Plan. There are
2,000,000 shares of common stock reserved for issuance under the Incentive Plan
and, as of September 30, 1999, there were 842,500 options outstanding under the
Incentive Plan. The purpose of the Incentive Plan is to provide executive
officers, directors and key employees with additional incentives by enabling
such persons to increase their ownership interests in RailWorks. Individual
awards under the Incentive Plan may take the form of one or more of: (1) either
incentive stock options ("ISOs") or non-qualified stock options ("NQSOs," and
together with ISOs, "Options"); (2) stock appreciation rights ("SARs"); (3)
restricted or deferred stock; (4) dividend equivalents; (5) bonus shares and
awards in lieu of RailWorks obligations to pay cash compensation; and (6) other
awards the value of which is based in whole or in part upon the value of the
common stock. Upon a change of control of RailWorks, as defined in the Incentive
Plan, some of the conditions and restrictions relating to an award with respect
to the exercisability or settlement of such award will lapse.


     The Compensation Committee administers the Incentive Plan and generally
selects the individuals who receive awards. In addition, the Audit Committee
determines the type and number of awards and the terms and conditions of those
awards (including exercise prices, vesting and forfeiture conditions,
performance conditions and periods during which awards will remain outstanding).
The Incentive Plan also provides that no participant may be granted in any
calendar year awards which may be settled by delivery of more than 100,000
shares and limits payments under cash-settled awards in any calendar year to an
amount equal to the fair market value of that number of shares.

                                       69
<PAGE>   75


     On October 26, 1999, the board of directors approved an amendment to the
Incentive Plan which was effective as of January 1, 1999. The amendment adds
consultants to the category of persons entitled to receive non-qualified stock
options. The amendment also provides that the limitation on the number of
options that may be granted during any calendar year shall apply only to key
employees who are officers or directors at the time of the grant. Accordingly,
options granted to consultants would not be subject to this limitation.


     RailWorks generally will be entitled to a tax deduction equal to the amount
of compensation realized by a participant through awards under the Incentive
Plan, except that (1) no deduction is permitted in connection with ISOs if the
participant holds the shares acquired upon exercise for the required holding
periods, and (2) deductions for some awards could be limited under the $1.0
million deductibility cap of Section 162(m) of the Internal Revenue Code of
1986, as amended (the "Code"). This limitation, however, should not apply to
awards granted under a plan during a grace period that expires in August 2001,
and should not apply to certain options, SARs and performance-based awards
granted thereafter if RailWorks complies with certain requirements under Section
162(m) of the Code.

     The Incentive Plan will remain in effect until terminated by the board of
directors. The Incentive Plan may be amended by the board of directors without
the consent of the stockholders of RailWorks, except that any amendment,
although effective when made, will be subject to stockholder approval if
required by any federal or state law or regulation or by the rules of any stock
exchange or automated quotation system on which the common stock may then be
listed or quoted.

              CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

     Set forth below is a description of certain transactions and relationships
between RailWorks and certain officers, directors and principal stockholders of
the Company. In addition, set forth below is certain information regarding

Companies and their respective officers, directors and principal stockholders.

GENERAL

members of the board of directors.

ACQUISITION OF CERTAIN FOUNDING COMPANIES

     On August 4, 1998, concurrently with the consummation of the IPO, RailWorks

     Michael R. Azarela, former Chief Executive Officer of Comstock, is
Executive Vice President and Chief Financial Officer of RailWorks. John Kennedy,
then President of Kennedy, is the Vice President and Chief Operating
Officer -- Track Contractors and a director of RailWorks. Upon completion of the
IPO, Scott D. Brace, President of Railroad Service became a director of
RailWorks. Each of Messrs. Azarela, Kennedy and Brace entered into a two-year
employment agreement with RailWorks in connection with the acquisition of the
Founding Companies.

COMSTOCK

     Effective January 1, 1997, Comstock acquired all of the outstanding stock
of L.K. Comstock from Spie for $5.0 million plus a contingent payment of up to
$5.0 million based on 1997, 1998 and 1999 pre-tax income. In May 1998, Comstock
agreed to pay Spie $1.6 million in lieu of such contingent payment, which amount
was paid by RailWorks on September 8, 1998.

     In connection with the Comstock Acquisition, Comstock, L.K. Comstock, Spie
and CGI entered into an Indemnity and Cooperation Agreement pursuant to which
L.K. Comstock issued a contingent promissory note to Spie in the amount of
approximately $14.9 million (the "Contingent Note") collateralized by any
proceeds derived from three projects (the "Spie Projects") for which Comstock
had not been fully paid. Each of these projects is the subject of a lawsuit in
which L.K. Comstock seeks payment of a portion of the contract price. In each
proceeding, the defendant has filed a counterclaim against L.K. Comstock for
breach of contract. Spie is obligated to indemnify L.K. Comstock for all losses
and expenses incurred with respect to these lawsuits. The Contingent Note is
payable only from amounts collected by L.K. Comstock with respect to the Spie
Projects prior to April 3, 2007, at which time the Contingent Note will be
canceled. As such, Spie and any successor or creditor may not look to any other
assets of L.K. Comstock or RailWorks to satisfy the Contingent Note. Because
there is a right of offset for any gains or losses incurred in connection with
the Spie Projects, neither the Contingent Note nor the right to receive proceeds
from the Spie Projects is reflected in Comstock's financial statements, the
RailWorks Consolidated Financial Statements or the RailWorks Pro Forma Financial
Statements.

LOANS TO OFFICERS

     Pursuant to the employment agreements, RailWorks made loans to certain of
its executive officers to cover income taxes due with respect to grants of
restricted common stock. These loans, which are due in full on August 4, 2003,
were in the following principal amounts: John G. Larkin -- $3,982,245; Michael
R. Azarela -- $876,236; and John Kennedy -- $834,047.

                          DESCRIPTION OF CAPITAL STOCK

     The authorized capital stock of RailWorks consists of 100,000,000 shares of
common stock, par value $.01 per share and 10,000,000 shares of preferred stock,
par value $.01 per share. The following summary description of the capital stock
of RailWorks is a summary only and is subject to the detailed provisions of, and
qualified in its entirety by reference to, the Company's Certificate of
Incorporation and Bylaws of RailWorks, copies of which are available from
RailWorks by writing or calling our principal executive offices, and to the
applicable provisions of the Delaware General Corporation Law ("DGCL").

COMMON STOCK

     The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. Subject to the
rights of any holders of preferred stock, holders of common stock are entitled
to receive ratably such dividends as may be declared by the board of directors
out of funds legally available. In the event of a liquidation, dissolution or
winding up of the Company, holders of the common stock are entitled to share
ratably in the distribution of all assets remaining after payment of
liabilities, subject to the rights of any holders of preferred stock of
RailWorks. The holders of common stock have no preemptive rights to subscribe
for additional shares of RailWorks and no right to convert their common stock
into any other securities. In addition, there are no redemption or sinking fund
provisions applicable to the common stock. All of the outstanding shares of
common stock are fully paid and nonassessable.

PREFERRED STOCK

     RailWorks has 10,000,000 shares of authorized preferred stock. On October
8, 1998, the Company issued 13,700 shares of preferred stock, designated Series
A convertible preferred stock, to Deutsche Bank Securities Inc. (formerly BT
Alex. Brown Incorporated), in exchange for 1,370,000 shares of common stock. The
stock exchange reduced Deutsche Bank Securities Inc.'s common stock holdings to
satisfy the Bank Holding Company Act (the "BHCA"). The BHCA requires that a bank
holding company own less than 5% of the voting stock of a publicly-traded
corporation. Each share of Series A convertible preferred stock is convertible
into 100 shares of common stock; however, subject to certain exceptions allowed
by the BHCA, conversion is prohibited if, after the conversion, Deutsche Bank
Securities Inc. would own 5% or more of the common stock. Shares of Series A
convertible preferred stock carry no voting rights, share ratably with shares of
common stock as to dividend distributions as if shares of Series A convertible
preferred stock had been converted to shares of common stock and have a
liquidation preference over shares of common stock.

     The board of directors is authorized to provide for the issuance of
additional classes and series of preferred stock out of remaining undesignated
shares, and the board of directors may establish the voting powers,
designations, preferences and relative, participating, optional or other special
rights and qualifications, limitations or restrictions of any such additional
class or series of preferred stock, including the dividend rights, dividend
rate, terms of redemption, redemption price or prices, conversion rights and
liquidation preferences of the shares constituting any series, without any
further vote or action by the stockholders of the Company. The issuance of
preferred stock by the board of directors could have the effect of making it
more difficult for a third party to acquire a majority of the outstanding voting
stock of RailWorks, thereby delaying, deferring or preventing a change in
control of RailWorks.

CERTAIN PROVISIONS OF DELAWARE LAW AND THE COMPANY'S CERTIFICATE OF
INCORPORATION AND BYLAWS

     We are subject to the provisions of Section 203 of the DGCL. Section 203
prohibits a publicly held Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless the business combination is approved in a prescribed manner.
A "business combination" includes a merger, asset sale or other transaction
resulting in a financial benefit to the interested stockholder. Subject to
certain exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns or within three years prior to the proposed
business combination has owned 15% or more of the corporation's voting stock.

     Our Certificate of Incorporation provides that liability of directors of
RailWorks is eliminated to the fullest extent permitted under Section 102(b)(7)
of the DGCL. As a result, no director of RailWorks will be liable to RailWorks
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability: (i) for any breach of the director's duty of
loyalty to RailWorks 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 any willful or negligent payment of an unlawful dividend, stock
purchase or redemption; or (iv) for any transaction from which the director
derived an improper personal benefit.

     Our Bylaws provide that the board of directors be elected to staggered
one-, two-and three-year terms and, thereafter, for successive three-year terms.
In addition, directors may only be removed from office for cause. These
provisions of the Bylaws could discourage potential acquisition proposals and
could delay or prevent a change in control of RailWorks.

                         DESCRIPTION OF CREDIT FACILITY


     Since the IPO, cash for acquisitions and working capital has been financed
by funds generated from operations, together with borrowings under the Company's
three-year, $105 million senior secured revolving credit facility with Bank of
America, N.A. ("B of A"). The credit facility matures on August 5, 2002, subject
to acceleration upon the occurrence of an event of default or a change in
control. Of the $105 million senior secured revolving credit facility, $90
million can be borrowed by RailWorks (the "U.S. credit facility"), and $15
million can be borrowed by Canadian subsidiaries of RailWorks (the "Canadian
credit facility"). Borrowings under the credit facility bear interest, at our
option, at an interest rate equal to (1) LIBOR plus the applicable margin for
LIBOR loans, which ranges from 125 basis points to 250 basis points based on the
ratio of Funded Debt to EBITDA (as such terms are defined in the credit
facility), (2) the Base Rate (defined as the higher of (a) the NationsBank prime
rate and (b) the Federal Funds rate plus 50 basis points) plus up to 100 basis
points based on the ratio of Funded Debt to EBITDA or (3) a rate negotiated with
B of A at the time of borrowing for up to $5 million of the U.S. credit facility
available to RailWorks as a swing line. In addition, borrowings under the
Canadian credit facility can be funded through bankers' acceptances, issued at a
discount to face value. As of September 30, 1999, borrowings under the credit
facility bore interest at a weighted average interest rate of 9.0% per annum.


     Borrowings under the U.S. credit facility are secured by a first priority
lien on all capital stock of our U.S. subsidiaries, 66% of the voting capital
stock of our non-U.S. subsidiaries, all non-voting capital stock of our non-U.S.
subsidiaries and all of our accounts receivable and the accounts receivable of
our U.S. subsidiaries. Repayment of the U.S. credit facility is guaranteed by
all of our U.S. subsidiaries. Borrowings under the Canadian credit facility are
secured by a first priority lien on all capital stock of our U.S. and non-U.S.
subsidiaries and all accounts receivable of RailWorks and its subsidiaries,
other than Canadian subsidiaries, and by a second priority lien on all accounts
receivable of the Canadian subsidiaries. Repayment of the Canadian credit
facility
                                       74
<PAGE>   80

is guaranteed by RailWorks and all of its subsidiaries. The credit facility
contains usual and customary events of default as well as financial covenants
for RailWorks regarding, among other things, debt coverage, net worth and
earnings. The credit facility also contains covenants and provisions that
restrict, among other things, the ability of RailWorks and its subsidiaries to:
(1) incur additional indebtedness and liens on their property, (2) merge or
consolidate with or acquire another person or engage in other fundamental
changes, (3) make certain acquisitions and investments, (4) make dividend and
certain other payments and (5) engage in certain sales, sale-leasebacks and
certain dispositions of property. As of the date of this prospectus, we were in
compliance with all covenants under the credit facility.


                       DESCRIPTION OF TERM LOAN FACILITY



     On November 5, 1999, we entered into a term loan facility with the lenders
named therein. Under the term loan facility, at December 6, 1999, we had $30.0
million of borrowings outstanding, which bore interest at a weighted average
annual rate of 9.83% as of such date. Borrowings outstanding under the term loan
facility mature on November 5, 2004. Borrowings under the term loan facility
bear interest, at our option, at an interest rate equal to (1) the Base Rate
plus 200 basis points or (2) the Eurodollar Rate plus 375 basis points. The
interest rate is increased by 2% upon the occurrence, and during the
continuance, of an event of default. The term loan facility is guaranteed by all
of our domestic subsidiaries.

                          DESCRIPTION OF THE NEW NOTES

     The form and terms of the new notes and the old notes are identical in all
material respects, except that transfer restrictions and registration rights
applicable to the old notes do not apply to the new notes.

     The old notes were, and the new notes will be, issued under the same
indenture as the existing notes, which is dated as of April 7, 1999, among
RailWorks, the Subsidiary Guarantors and First Union National Bank, as trustee.
The following description of the material provisions of the indenture is a
summary only. It does not include all of the provisions of the indenture. We
urge you to read the indenture because it defines your rights. The terms of the
notes include those stated in the indenture and those made part of the indenture
by reference to the Trust Indenture Act of 1939, which will govern the indenture
upon effectiveness of the registration statement that includes this prospectus.
A copy of the indenture may be obtained from RailWorks upon request. You can
find definitions of certain capitalized terms used in this description under
"-- Certain Definitions." For purposes of this section, references to "we,"
"our," "us" and "RailWorks" include only RailWorks Corporation and not its
subsidiaries. References in this section to the "notes" are references to both
the old notes and the new notes.

     The notes are general unsecured obligations of RailWorks, and rank
subordinate in right of payment to all Senior Debt of RailWorks.

     We will issue the new notes in fully registered form in denominations of
$1,000 and integral multiples. The trustee will initially act as paying agent
and registrar for the new notes. The new notes may be presented for registration
or transfer and exchange at the offices of the registrar. We may change any
paying agent and registrar without notice to note holders. We will pay
principal, and premium, if any, on the notes at the trustee's corporate office
in New York, New York. At our option, interest may be paid at the trustee's
corporate trust office or by check mailed to the registered address of holders.
Any notes that remain outstanding after the completion of the exchange offer,
together with the new notes issued in connection with the exchange offer, will
be treated as a single class of securities under the indenture.

PRINCIPAL, MATURITY AND INTEREST

     The notes are limited in aggregate principal amount to $250.0 million, of
which $125.0 million in aggregate principal amount was issued on April 7, 1999,
which we refer to as the "existing notes", and $50.0 million in aggregate
principal amount was issued on September 30, 1999. The notes mature on April 15,
2009. Additional notes may be issued from time to time, subject to the
limitations set forth under "-- Certain Covenants -- Limitation on Incurrence of
Additional Indebtedness" and restrictions contained in the Credit Agreement. Any
additional notes will be part of the same issue as the existing notes, the old
notes and the new notes and will vote on all matters with the existing notes,
the old notes and the new notes. Unless otherwise indicated, references in this
section to the notes include the existing notes but do not include the
additional notes. No offering of any such additional notes is being or shall be
deemed to be made by this prospectus. In addition, there can be no assurance as
to when or whether RailWorks will issue any such additional notes or as to the
aggregate principal amount of any such additional notes.

     Interest on the notes accrues at the annual rate of 11 1/2% and is payable
semi-annually in cash on each April 15 and October 15 commencing on October 15,
1999, to the persons who are registered holders at the close of business on the
April 1 and October 1 immediately preceding the applicable interest payment
date. Interest on the notes accrues from the most recent date to which interest
has been paid or, if no interest has been paid, from and including September 30,
1999. Interest is computed on the basis of a 360-day year comprised of twelve
30-day months.

     The notes are not entitled to the benefit of any mandatory sinking fund.

notice, at the redemption prices expressed as percentages of the principal
amount as described in the following table, plus accrued and unpaid interest to

     Optional Redemption.  Except as described below, the notes are not
redeemable before April 15, 2004. After April 15, 2004, we may redeem the notes
at our option, in whole or in part, upon not less than 30 nor more than 60 days'

     In addition, we must pay accrued and unpaid interest on the notes we
redeem.

     Optional Redemption upon Equity Offerings.  At any time, which may be more
than once, on or prior to April 15, 2002, we may, at our option, use the net
cash proceeds of one or more Equity Offerings to redeem up to 35% of the
principal amount of the notes issued under the indenture at a redemption price
of 111.500% of the principal amount of such notes plus accrued and unpaid
interest, if any, to the redemption date; provided that:

          (1) at least 65% of the principal amount of notes issued under the
     indenture remains outstanding immediately after any such redemption; and

          (2) we make such redemption not more than 120 days after the
     consummation of any such Equity Offering.

     "Equity Offering" means public or private offering of our Qualified Capital
Stock; provided that, in the event such equity offering is not in the form of an
underwritten public offering registered under the Securities Act, the proceeds
we directly or indirectly receive from such offering are not less than $10.0
million.

SELECTION AND NOTICE OF REDEMPTION

     In the event that we choose to redeem less than all of the notes, the
trustee will select notes for redemption either:

          (1) in compliance with the requirements of the principal national
     securities exchange, if any, on which the notes are listed; or,

          (2) on a pro rata basis, by lot or by such method as the trustee shall
     deem fair and appropriate.

                                       77
<PAGE>   83

     No notes of a principal amount of $1,000 or less shall be redeemed in part.
If a partial redemption is made with the proceeds of an Equity Offering, the
trustee will select the notes only on a pro rata basis or on as nearly a pro
rata basis as is practicable, subject to DTC procedures, unless such method is
otherwise prohibited. Notice of redemption will be mailed by first-class mail at
least 30 but not more than 60 days before the redemption date to each holder of
notes to be redeemed at the holder's registered address. On and after the
redemption date, interest will cease to accrue on notes or portions thereof
called for redemption as long as we have deposited with the paying agent funds
in satisfaction of the applicable redemption price.

SUBORDINATION

     The payment of all Obligations on the notes is subordinated in right of
payment to the prior payment in full in cash or Cash Equivalents of all
Obligations on Senior Debt of RailWorks.

     The holders of Senior Debt are entitled to receive payment in full in cash
or Cash Equivalents of all Obligations due in respect of Senior Debt. The
payment includes any interest accruing subsequent to a bankruptcy or other
similar proceeding, whether or not such interest is an allowed claim enforceable
against RailWorks in a bankruptcy case, before the holders of notes will be
entitled to receive any payment with respect to the notes, or any note is
acquired for cash or property or otherwise, in the event of any distribution to
our creditors:

          (1) in a liquidation or dissolution of RailWorks;

          (2) in a bankruptcy, reorganization, insolvency, receivership or
     similar proceeding relating to RailWorks or its property;

          (3) in an assignment for the benefit of creditors; or

          (4) in any marshaling of RailWorks's assets and liabilities.

     We also may not make any payment in respect of the notes, or acquire any
notes for cash or property or otherwise, if:

          (1) a payment default on Designated Senior Debt occurs and is
     continuing; or

          (2) any other default occurs and is continuing on Designated Senior
     Debt (as such event of default is defined in the instrument creating or
     evidencing such Designated Senior Debt) that permits holders of the
     Designated Senior Debt to accelerate its maturity and the trustee receives
     a notice of such default (a "Payment Blockage Notice") from the
     Representative of any Designated Senior Debt.

     Payments on the notes may and shall be resumed:

          (1) in the case of a payment default, upon the date on which such
     default is cured or waived; and

          (2) in case of a nonpayment default, the earliest of the date on which
     such nonpayment default is cured or waived or ceases to exist or such
     Designated Senior Debt is paid in full (so long as no other event of
     default exists), or the trustee receives notice from the Representative for
     the respective issue of Designated Senior Debt terminating the Blockage
     Period, or 180 days after the date on which the applicable Payment Blockage
     Notice is received, unless the maturity of any Designated Senior Debt has
     been accelerated.

     No new Payment Blockage Notice may be delivered unless and until 360 days
have elapsed since the initial effective date of the immediately prior Payment
Blockage Notice.

     No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default shall have
been cured or waived for a period of not less than 90 days.

                                       78
<PAGE>   84

     We must promptly notify holders of Senior Debt if payment of the notes is
accelerated because of an Event of Default.

     As a result of the subordination provisions described above, in the event
of a bankruptcy, liquidation or reorganization of RailWorks, holders of the
notes may recover less ratably than creditors of RailWorks who are holders of
Senior Debt. See "Risk Factors -- Risks Relating to the Notes -- The Notes Rank
Behind Other Indebtedness".


     Pro forma basis for the acquisition of the 1999 Acquired Companies,
borrowings under the new term loan facility and the sale of the old notes and
the application of the net proceeds, at September 30, 1999, the aggregate amount
of senior debt outstanding would have been approximately $50.4 million, and
RailWorks would have had $82.5 million available for borrowing under the Credit
Facility.


GUARANTEES

     The Guarantors, which will initially include all of our domestic Restricted
Subsidiaries existing on September 30, 1999, will jointly and severally fully
and unconditionally guarantee, on an unsecured senior subordinated basis, our
obligations under the indenture and the notes. Each Guarantee will be
subordinated to Guarantor Senior Debt on the same basis as the notes are
subordinated to Senior Debt. For purposes hereof, the trustee and the holders
shall have the right to receive and/or retain payments by any of the Guarantors
only at such times as they may receive and/or retain payments from RailWorks in
respect of the notes pursuant to the indenture. The obligations of each
Guarantor under its Guarantee will be limited as necessary to prevent the
Guarantee from constituting a fraudulent conveyance or fraudulent transfer under
applicable law.

     Each Guarantor may consolidate with or merge into or sell its assets to the
Company or another Guarantor that is a Wholly Owned Restricted Subsidiary of
RailWorks without limitation, or with other Persons upon the terms and
conditions set forth in the indenture. See "-- Certain Covenants -- Merger,
Consolidation and Sale of Assets". In the event all or substantially all of the
assets or all of the Capital Stock of a Guarantor is sold by RailWorks and the
sale complies with the provisions set forth in "-- Certain
Covenants -- Limitation on Asset Sales", the Guarantor's Guarantee will be
automatically and unconditionally discharged and released.

     Separate financial statements of the Guarantors are not included herein
because such Guarantors are jointly and severally liable for our obligations
pursuant to the notes, and the aggregate net assets, earnings and equity of the
Guarantors and RailWorks are substantially equivalent to the net assets,
earnings and equity of RailWorks on a consolidated basis.

HOLDING COMPANY STRUCTURE

     RailWorks is a holding company. We have no material operations of our own
and only limited assets. Accordingly, we depend upon the distribution of the
earnings of our subsidiaries, whether in the form of dividends, advances or
payments on account of intercompany obligations, to service our debt
obligations. We cannot assure you that, after providing for all prior claims,
there would be sufficient assets available from RailWorks and our subsidiaries
to satisfy the claims of the holders of our new notes.

CHANGE OF CONTROL

     In the event of a Change of Control, each holder will have the right to
require that we purchase all or a portion of such holder's new notes pursuant to
the offer described below, the "Change of Control Offer", at a purchase price
equal to 101% of the principal amount of the new notes plus accrued and unpaid
interest, if any, to the date of purchase.

     Within 30 days following the date upon which the Change of Control
occurred, we must send, by first class mail, a notice to each holder, with a
copy to the trustee, which notice shall
                                       79
<PAGE>   85

govern the terms of the Change of Control Offer. Such notice shall state, among
other things, the purchase date, which must be no earlier than 30 days nor later
than 60 days from the date such notice is mailed, other than as may be required
by law, the date of such purchase being the "Change of Control Payment Date".
Holders electing to have a note purchased pursuant to a Change of Control Offer
will be required to surrender the note, with the form entitled "Option of Holder
to Elect Purchase" on the reverse of the note completed, to the paying agent at
the address specified in the notice prior to the close of business on the third
business day prior to the Change of Control Payment Date.

     If we make a Change of Control Offer, we cannot guarantee that we will have
available funds sufficient to pay the Change of Control purchase price for all
the notes that might be delivered by holders seeking to accept the Change of
Control Offer. In the event we are required to purchase outstanding notes
pursuant to a Change of Control Offer, we expect that we would seek third-party
financing to the extent we do not have available funds to meet our purchase
obligations. However, we cannot guarantee that we would be able to obtain the
necessary financing.

     In addition, we cannot guarantee that our debt instruments will permit us
to make a Change of Control Offer. Our credit facility does not permit us to
make a Change of Control Offer and, in order to make such offer, we would be
required to pay off the credit facility in full or seek a waiver from the
lenders under the credit facility in order to make the Change of Control Offer.
A Change of Control is an event of default under the credit facility and would
entitle the lenders to accelerate all amounts owing under the credit facility.
Any future credit agreements or other agreements relating to Senior Debt to
which we become a party may contain similar restrictions and provisions.
Moreover, the exercise by the holders of their rights to require us to
repurchase the notes could cause a default under such indebtedness, even if the
Change of Control itself does not, due to the financial effect of such
repurchase on RailWorks. Failure to make a Change of Control Offer, even if
prohibited by our debt instruments, would constitute a default under the
indenture. See "Risk Factors -- Risks Relating to the New Notes -- We May Not
Have Sufficient Cash to Purchase the New Notes Upon a Change of Control."

     We are not required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in compliance with
the requirements applicable to a Change of Control Offer made by RailWorks and
purchases all notes validly tendered and not withdrawn under such Change of
Control Offer.

     Neither the board of directors of RailWorks nor the trustee may waive the
covenant relating to a holder's right to redemption when a Change of Control
occurs. Each holder's right to require us to purchase that holder's notes upon a
Change of Control, and the restrictions in the indenture described in this
prospectus on the ability of RailWorks and its Restricted Subsidiaries to incur
additional Indebtedness, to grant liens on their property, to make Restricted
Payments and to make Asset Sales, may also make a takeover of RailWorks more
difficult or discourage it, whether favored or opposed by our management.
Carrying out Change of Control Offers may sometimes require redemption or
repurchase of the notes, and we cannot guarantee that we or the acquiring party
will have sufficient financial resources to do so. These restrictions and the
restrictions on transactions with affiliates may, in certain circumstances, make
more difficult or discourage any leveraged buyout of RailWorks or any of its
subsidiaries by our management. While the restrictions cover a wide variety of
arrangements that have traditionally been used to effect highly leveraged
transactions, the indenture may not afford the holders of new notes protection
in all circumstances from the adverse aspects of a highly leveraged transaction,
reorganization, restructuring, merger or similar transaction.

     We will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and regulations in connection with the repurchase
of notes pursuant to a Change of Control Offer. To the extent that the
provisions of any securities laws or regulations conflict with the "Change of
Control" provisions of the indenture, we will comply with the applicable

                                       80
<PAGE>   86

securities laws and regulations and will not be deemed to have breached our
obligations under the "Change of Control" provisions of the indenture by doing
so.

CERTAIN COVENANTS

     Limitation on Incurrence of Additional Indebtedness.  We will not, and will
not permit any of our Restricted Subsidiaries to, directly or indirectly,
create, incur, assume, guarantee, acquire, become liable, contingently or
otherwise, with respect to, or otherwise become responsible for payment of
(collectively, "incur") any Indebtedness, other than Permitted Indebtedness;
provided, however, that if no Default or Event of Default shall have occurred
and be continuing at the time of or as a consequence of the incurrence of any
such Indebtedness, RailWorks or any of its Restricted Subsidiaries that is or,
upon such incurrence, becomes a Guarantor may incur Indebtedness (including,
without limitation, Acquired Indebtedness) and Restricted Subsidiaries of
RailWorks that are not Guarantors may incur Acquired Indebtedness, in each case
if on the date of the incurrence of such Indebtedness, after giving effect to
the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of
RailWorks is greater than (x) 2.0 to 1.0 if the date of such occurrence is on or
prior to April 1, 2001, or (y) 2.25 to 1.0 if the date of such occurrence is on
or after April 1, 2001 and prior to April 1, 2004, or (z) 2.5 to 1.0 if the date
of such occurrence is on or after April 1, 2004.

     Limitation on Restricted Payments.  We will not, and will not cause or
permit any of our Restricted Subsidiaries to, directly or indirectly:

          (1) declare or pay any dividend or make any distribution, other than
     dividends or distributions payable in Qualified Capital Stock of RailWorks
     or in options, warrants or other rights to purchase Qualified Capital Stock
     of RailWorks, on or in respect of shares of the RailWorks Capital Stock to
     holders of such Capital Stock;

          (2) purchase, redeem or otherwise acquire or retire for value any
     Capital Stock of RailWorks or any warrants, rights or options to purchase
     or acquire shares of any class of such Capital Stock, other than in either
     case any RailWorks Capital Stock or other securities owned by RailWorks or
     any of its Restricted Subsidiaries;

          (3) make any principal payment on, purchase, defease, redeem, prepay,
     decrease or otherwise acquire or retire for value, prior to any scheduled
     final maturity, scheduled repayment or scheduled sinking fund payment, any
     Indebtedness of RailWorks that is subordinate or junior in right of payment
     to the notes, (i) other than any such subordinated Indebtedness owed to
     RailWorks or any of its Restricted Subsidiaries and (ii) except the
     prepayment, purchase, repurchase or other acquisition or retirement of
     Indebtedness in anticipation of satisfying a sinking fund obligation,
     principal installment or final maturity, in each case due within one year
     of the date of prepayment, purchase, repurchase or other acquisition or
     retirement; or

          (4) make any Investment (other than Permitted Investments) (each of
     the foregoing actions set forth in clauses (1), (2), (3) and (4) being
     referred to as a "Restricted Payment");

     if at the time of such Restricted Payment or immediately after giving
effect to it,

             (i) a Default or an Event of Default shall have occurred and be
        continuing; or

             (ii) we are not able to incur at least $1.00 of additional
        Indebtedness, other than Permitted Indebtedness, in compliance with the
        "Limitation on Incurrence of Additional Indebtedness" covenant; or

                                       81
<PAGE>   87

             (iii) the aggregate amount of Restricted Payments, including such
        proposed Restricted Payment made subsequent to April 7, 1999 exceeds the
        sum of:

                (w) 50% of the cumulative Consolidated Net Income, or if
           cumulative Consolidated Net Income shall be a loss, minus 100% of
           such loss, of RailWorks earned subsequent to April 7, 1999 and on or
           prior to the date the Restricted Payment occurs (the "Reference
           Date"), and treating such period as a single accounting period; plus

                (x) 100% of the aggregate net cash proceeds received by
           RailWorks from any Person, other than a Restricted Subsidiary, from
           the issuance and sale subsequent to April 7, 1999 and on or prior to
           the Reference Date of (i) Qualified Capital Stock of RailWorks and
           (ii) Indebtedness or Disqualified Capital Stock that has been
           converted into or exchanged for Qualified Capital Stock together with
           the aggregate net cash proceeds received by RailWorks or any
           Restricted Subsidiary at the time of such conversion or exchange;
           plus

                (y) without duplication of any amounts included in clause (iii)
           (x) above, 100% of the aggregate net cash proceeds of any equity
           contribution received by RailWorks from a holder of RailWorks Capital
           Stock, excluding, in the case of clauses (iii) (x) and (y), any net
           cash proceeds from an Equity Offering to the extent used to redeem
           the notes in compliance with the provisions set forth under
           "Redemption -- Optional Redemption upon Equity Offerings"; plus

                (z) without duplication, the sum of:

                    (1) the aggregate amount returned in cash on or with respect
               to Investments, except for Permitted Investments, made subsequent
               to April 7, 1999 whether through interest payments, principal
               payments, dividends or other distributions or payments;

                    (2) the net cash proceeds received by RailWorks or any of
               its Restricted Subsidiaries from the disposition of all or any
               portion of such Investments, other than to a Restricted
               Subsidiary of RailWorks; and

                    (3) upon redesignation of an Unrestricted Subsidiary as a
               Restricted Subsidiary, the fair market value of such Subsidiary;
               provided, however, that the sum of clauses (1), (2) and (3) above
               shall not exceed the aggregate amount of all such Investments
               made subsequent to April 7, 1999.

     Notwithstanding the foregoing, the provisions set forth in the immediately
preceding paragraph do not prohibit:

          (1) the payment of any dividend within 60 days after the date of
     declaration of such dividend if the dividend would have been permitted on
     the date of declaration;

          (2) the acquisition of any shares of Capital Stock of RailWorks,
     either (i) solely in exchange for shares of Qualified Capital Stock of
     RailWorks or (ii) through the application of net proceeds of a
     substantially concurrent sale for cash, other than to a Restricted
     Subsidiary, of shares of Qualified Capital Stock;

          (3) the acquisition of any Indebtedness of RailWorks that is
     subordinate or junior in right of payment to the notes either (i) solely in
     exchange for shares of Qualified Capital Stock of RailWorks, or (ii)
     through the application of net proceeds of a substantially concurrent sale
     for cash, other than to a Restricted Subsidiary of RailWorks of (a) shares
     of Qualified Capital Stock of RailWorks or (b) Refinancing Indebtedness;

          (4) so long as no Default or Event of Default shall have occurred and
     be continuing, repurchases by RailWorks of its Capital Stock from
     employees, former employees, directors or
                                       82
<PAGE>   88

     former directors of RailWorks or any of its Subsidiaries or their
     authorized representatives upon the death, disability or termination of
     employment of such employees or former employees, or termination of the
     term of such director or former director, in an aggregate amount not to
     exceed $1.0 million in any calendar year;

          (5) loans and advances made to officers or other employees to make tax
     payments associated with stock grants and/or the grant or exercise of stock
     options (i) pursuant to existing employment agreements in an amount not to
     exceed $6.5 million within six months after April 7, 1999 and (ii) in an
     amount not to exceed $1.0 million in any calendar year thereafter;

          (6) loans and advances to officers and other employees of RailWorks or
     any of its Restricted Subsidiaries for the exercise of stock options in an
     amount not to exceed $1.0 million at any one time outstanding;

          (7) the repurchase of any subordinated Indebtedness at a purchase
     price not greater than 101% of the principal amount of such subordinated
     Indebtedness in the event of a "change of control" in accordance with
     provisions similar to the "Change of Control" covenant; provided that,
     prior to or simultaneously with such repurchase, RailWorks has made the
     Change of Control Offer as provided in such covenant with respect to the
     notes and has repurchased all notes validly tendered for payment in
     connection with such Change of Control Offer;

          (8) payments or distributions to stockholders pursuant to appraisal
     rights in respect of up to 10% of the Capital Stock of RailWorks or any
     Restricted Subsidiary required by law in connection with a consolidation,
     merger or transfer of assets that complies with the covenant described
     under "-- Merger, Consolidation and Sale of Assets"; and

          (9) other Restricted Payments in an aggregate amount since April 7,
     1999 not to exceed $1.0 million.

     In determining the aggregate amount of Restricted Payments made subsequent
to April 7, 1999 in accordance with clause (iii) of the immediately preceding
paragraph, amounts expended pursuant to clauses (1), (2) (ii), (4), (5), (6),
(7) and (9) shall be included in such calculation.

     Not later than the date of making any Restricted Payment, we shall deliver
to the trustee an officers' certificate stating that such Restricted Payment
complies with the indenture and setting forth in reasonable detail the basis
upon which the required calculations were computed, which calculations may be
based upon our latest available internal quarterly financial statements.

     Limitation on Asset Sales.  We will not, and will not permit any of our
Restricted Subsidiaries to, consummate an Asset Sale unless:

          (1) RailWorks or the applicable Restricted Subsidiary, as the case may
     be, receives consideration at the time of such Asset Sale at least equal to
     the fair market value of the assets sold or otherwise disposed of, as
     determined in good faith by our board of directors;

          (2) at least 75% of the consideration received by RailWorks or the
     Restricted Subsidiary, as the case may be, from such Asset Sale shall be in
     the form of cash or Cash Equivalents and is received at the time of such
     disposition; provided that the amount of (x) any liabilities of RailWorks
     or any of its Restricted Subsidiaries (as shown on the most recent balance
     sheet of RailWorks or such Restricted Subsidiary), other than liabilities
     that are by their terms subordinated to the notes or any Guarantee, as the
     case may be, that are assumed by the transferee of any such assets pursuant
     to a customary novation agreement that releases RailWorks or such
     Restricted Subsidiary from further liability and (y) any securities, notes
     or other obligations received by RailWorks or any such Restricted
     Subsidiary from such transferee that are converted by RailWorks or such
     Restricted Subsidiary into cash, to the
                                       83
<PAGE>   89

     extent of the cash received, within 180 days after receipt, shall be deemed
     to be cash for the purposes of this clause (2); and

          (3) upon the consummation of an Asset Sale, RailWorks shall apply, or
     cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating
     to such Asset Sale within 360 days of receipt thereof either:

             (a) to prepay any Senior Debt and, in the case of any Senior Debt
        under any revolving credit facility, effect a permanent reduction in the
        availability under such revolving credit facility;

             (b) to make an investment in properties and assets that replace the
        properties and assets that were the subject of such Asset Sale or in
        properties and assets that will be used in the business of RailWorks and
        its Restricted Subsidiaries as existing on April 7, 1999 or in
        businesses reasonably related or ancillary thereto ("Replacement
        Assets"); or

             (c) a combination of prepayment and investment permitted by the
        foregoing clauses (3)(a) and (3)(b).

     On the 361st day after an Asset Sale or such earlier date, if any, as the
Board of Directors of RailWorks or of such Restricted Subsidiary determines not
to apply the Net Cash Proceeds relating to such Asset Sale as set forth in
clauses (3)(a), (3)(b) and (3)(c) of the preceding paragraph, each such date a
"Net Proceeds Offer Trigger Date", subject to the immediately succeeding
paragraph, such aggregate amount of Net Cash Proceeds that have not been applied
on or before such Net Proceeds Offer Trigger Date as permitted in clauses
(3)(a), (3)(b) and (3)(c) of the preceding paragraph (each a "Net Proceeds Offer
Amount") shall be applied by RailWorks or such Restricted Subsidiary to make an
offer to purchase, such offer being the "Net Proceeds Offer", on a date, the
"Net Proceeds Offer Payment Date", not less than 30 nor more than 60 days
following the applicable Net Proceeds Offer Trigger Date, from all holders on a
pro rata basis, that amount of notes equal to the Net Proceeds Offer Amount at a
price equal to 100% of the principal amount of the notes to be purchased, plus
accrued and unpaid interest thereon, if any, to the date of purchase.

     We may defer the Net Proceeds Offer until there is an aggregate unutilized
Net Proceeds Offer Amount equal to or in excess of $10.0 million resulting from
one or more Asset Sales, at which time, the entire unutilized Net Proceeds Offer
Amount, and not just the amount in excess of $10.0 million, shall be applied as
required pursuant to this paragraph. Upon completion of a Net Proceeds Offer,
the amount of Net Cash Proceeds and the aggregate unutilized Net Proceeds Offer
Amount will be reset to zero. Accordingly, to the extent that any Net Proceeds
remain after consummation of a Net Proceeds Offer, we may use such Net Proceeds
for any purpose not prohibited by the indenture.

     Notwithstanding the first two paragraphs of this covenant, RailWorks and
its Restricted Subsidiaries will be permitted to consummate an Asset Sale
without complying with such paragraphs to the extent that:

          (1) at least 75% of the consideration for such Asset Sale constitutes
     Replacement Assets; and

          (2) such Asset Sale is for fair market value; provided that any
     consideration not constituting Replacement Assets received by RailWorks or
     any of its Restricted Subsidiaries in connection with any Asset Sale
     permitted to be consummated under this paragraph shall constitute Net Cash
     Proceeds subject to the provisions of the first two paragraphs of this
     covenant.

     Each Net Proceeds Offer will be mailed to the record holders as shown on
the register of holders within 25 days following the Net Proceeds Offer Trigger
Date, with a copy to the trustee, and shall comply with the procedures set forth
in the indenture. Upon receiving notice of the
                                       84
<PAGE>   90

Net Proceeds Offer, holders may elect to tender their notes in whole or in part
in integral multiples of $1,000 in exchange for cash. To the extent holders
properly tender notes in an amount exceeding the Net Proceeds Offer Amount,
notes of tendering holders will be purchased on a pro rata basis. A Net Proceeds
Offer shall remain open for a period of 20 business days or such longer period
as may be required by law.

     We will comply with the requirements of Rule 14e-1 under the Exchange Act
and any other securities laws and regulations thereunder to the extent such laws
and regulations are applicable in connection with the repurchase of notes
pursuant to a Net Proceeds Offer. To the extent that the provisions of any
securities laws or regulations conflict with the "Asset Sale" provisions of the
indenture, we shall comply with the applicable securities laws and regulations
and shall not be deemed to have breached its obligations under the "Asset Sale"
provisions of the indenture by doing so.

     Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries. We will not, and will not permit any of our Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or permit to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to:

          (1) pay dividends or make any other distributions on or in respect of
     its Capital Stock;

          (2) make loans or advances or to pay any Indebtedness owed to
     RailWorks or any of its Restricted Subsidiaries; or

          (3) transfer any of its property or assets to RailWorks or any of its
     Restricted Subsidiaries, except for such encumbrances or restrictions
     existing under or by reason of:

             (a) applicable law;

             (b) the indenture, the Guarantees and the notes;

             (c) customary non-assignment provisions of any contract or any
        lease governing a leasehold interest of any of our Restricted
        Subsidiaries;

             (d) any instrument governing Acquired Indebtedness, which
        encumbrance or restriction is not applicable to any Person, or the
        properties or assets of any Person, other than the Person or the
        properties or assets of the Person so acquired;

             (e) the Credit Agreement and any other agreements in effect on
        April 7, 1999;

             (f) an agreement entered into for the sale or disposition of
        Capital Stock or assets of a Restricted Subsidiary or an agreement
        entered into for the sale of specified assets, in either case, so long
        as such encumbrance or restriction, by its terms, terminates upon
        consummation of such sale or termination of such agreements;

             (g) any agreement or instrument governing Indebtedness or Capital
        Stock of any Person in effect at the time it is acquired by RailWorks or
        any of its Restricted Subsidiaries;

             (h) purchase money obligations for assets acquired in the ordinary
        course of business that impose restrictions of the nature described in
        (3) above on the property so acquired;

             (i) customary provisions with respect to the disposition or
        distribution of assets in joint venture agreements and other similar
        agreements;

             (j) customary restrictions on transfers of property subject to a
        Lien permitted under the indenture imposed by the holder of such Lien;
        or

             (k) an agreement governing Indebtedness incurred to Refinance the
        Indebtedness issued, assumed or incurred pursuant to an agreement
        permitted above; provided,
                                       85
<PAGE>   91

        however, that the provisions relating to such encumbrance or restriction
        contained in any such Indebtedness are no less favorable to RailWorks in
        any material respect as determined by the RailWorks board of directors
        in their reasonable and good faith judgment than the provisions relating
        to such encumbrance or restriction contained in agreements referred to
        above.

     Limitation on Preferred Stock of Restricted Subsidiaries.  We will not
permit any of our Restricted Subsidiaries that are not Guarantors to issue any
Preferred Stock (other than to or to a Wholly Owned Restricted Subsidiary of
RailWorks) or permit any Person (other than RailWorks or a Wholly Owned
Restricted Subsidiary of RailWorks) to own any Preferred Stock of any Restricted
Subsidiary that is not a Guarantor. Notwithstanding the foregoing, nothing in
such covenant will prohibit Preferred Stock issued by a Person prior to the time
(A) such Person becomes a Restricted Subsidiary of RailWorks, (B) such Person
merges with or into a Restricted Subsidiary of RailWorks or (C) a Restricted
Subsidiary of RailWorks merges with or into such Person; provided that such
Preferred Stock was not issued or incurred by such Person in anticipation of a
transaction contemplated by subclause (A), (B) or (C) above.

     Limitation on Liens.  We will not, and will not permit any of our
Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
permit or suffer to exist any Liens of any kind against or upon any property or
assets of ours or of any of our Restricted Subsidiaries whether owned on, or
acquired after April 7, 1999, or any proceeds therefrom, or assign or otherwise
convey any right to receive income or profits therefrom unless:

          (1) in the case of Liens securing Indebtedness that is expressly
     subordinate or junior in right of payment to the notes, the notes are
     secured by a Lien on such property, assets or proceeds that is senior in
     priority to such Liens; and

          (2) in all other cases, the notes are equally and ratably secured,
     except for:

             (a) Liens existing as of April 7, 1999 to the extent and in the
        manner such Liens are in effect on April 7, 1999;

             (b) Liens securing Senior Debt and Liens securing Guarantor Senior
        Debt;

             (c) Liens securing the notes and the Guarantees;

             (d) Liens of RailWorks or a Wholly Owned Restricted Subsidiary of
        RailWorks on assets of any Restricted Subsidiary of RailWorks;

             (e) Liens securing Refinancing Indebtedness which is incurred to
        Refinance any Indebtedness which has been secured by a Lien permitted
        under the indenture and which has been incurred in accordance with the
        provisions of the indenture; provided, however, that such Liens: (i) are
        no less favorable to the holders and are not more favorable to the
        lienholders with respect to such Liens than the Liens in respect of the
        Indebtedness being Refinanced; and (ii) do not extend to or cover any
        property or assets of RailWorks or any of its Restricted Subsidiaries
        not securing the Indebtedness so Refinanced; and

             (f) Permitted Liens.

     Prohibition on Incurrence of Senior Subordinated Debt.  We will not, and
will not permit any Restricted Subsidiary that is a Guarantor to, incur or
suffer to exist Indebtedness that is senior in right of payment to the notes or
such Guarantor's Guarantee, as the case may be, and subordinate in right of
payment to any other Indebtedness of RailWorks or such Guarantor, as the case
may be.

     Merger, Consolidation and Sale of Assets.  We will not, in a single
transaction or series of related transactions, consolidate or merge with or into
any Person, or sell, assign, transfer, lease, convey or otherwise dispose of, or
permit any of our Restricted Subsidiaries to sell, assign, transfer, lease,
convey or otherwise dispose of, all or substantially all of our assets
(determined on a consolidated basis for RailWorks and its Restricted
Subsidiaries), whether as an entirety or substantially as an entirety to any
Person unless:

          (1) either:

             (a) RailWorks shall be the surviving or continuing corporation; or

             (b) the Person, if other than RailWorks, formed by such
        consolidation or into which RailWorks is merged or the Person which
        acquires by sale, assignment, transfer, lease, conveyance or other
        disposition the properties and assets of RailWorks and of its Restricted
        Subsidiaries substantially as an entirety, such Person being referred to
        as the "Surviving Entity":

                (x) shall be a corporation organized and validly existing under
           the laws of the United States or any State thereof or the District of
           Columbia; and

                (y) shall expressly assume, by supplemental indenture (in form
           and substance reasonably satisfactory to the trustee), executed and
           delivered to the trustee, the due and punctual payment of the
           principal of (and premium, if any) and interest on all of the notes
           and the performance of every covenant of the notes, the indenture and
           the registration rights agreement to be performed or observed by
           RailWorks;

          (2) immediately after giving effect to such transaction and the
     assumption contemplated by clause (1)(b)(y) above (including giving effect
     to any Indebtedness and Acquired Indebtedness incurred or anticipated to be
     incurred in connection with or in respect of such transaction), RailWorks
     or such Surviving Entity, as the case may be, (a) shall have a Consolidated
     Net Worth equal to or greater than the Consolidated Net Worth of RailWorks
     immediately prior to such transaction and (b) shall be able to incur at
     least $1.00 of additional Indebtedness, not including Permitted
     Indebtedness, pursuant to the "Limitation on Incurrence of Additional
     Indebtedness" covenant;

          (3) immediately before and immediately after giving effect to such
     transaction and the assumption contemplated by clause (1)(b)(y) above,
     including, without limitation, giving effect to any Indebtedness and
     Acquired Indebtedness incurred or anticipated to be incurred and any Lien
     granted in connection with or in respect of the transaction, no Default or
     Event of Default shall have occurred or be continuing; and

          (4) RailWorks or the Surviving Entity shall have delivered to the
     trustee an officers' certificate and an opinion of counsel, each stating
     that such consolidation, merger, sale, assignment, transfer, lease,
     conveyance or other disposition and, if a supplemental indenture is
     required in connection with such transaction, such supplemental indenture
     comply with the applicable provisions of the indenture and that all
     conditions precedent in the indenture relating to such transaction have
     been satisfied.

     Notwithstanding the foregoing clauses (2), (3) and (4), (a) any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its
property and assets to RailWorks or any other Restricted Subsidiary and (b)
RailWorks may merge with an Affiliate incorporated solely for the purpose of
reincorporating RailWorks in another jurisdiction in the United States.

     For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more of our Restricted
Subsidiaries, the Capital Stock of which constitutes all or substantially all of
the properties and assets of RailWorks, shall be deemed to be the transfer of
all or substantially all of the properties and assets of RailWorks.
                                       87
<PAGE>   93

     The indenture provides that upon any consolidation, combination or merger
or any transfer of all or substantially all of the assets of RailWorks in
accordance with the foregoing, in which RailWorks is not the Surviving Entity,
the Surviving Entity shall succeed to, and be substituted for, and may exercise
every right and power of, RailWorks under the indenture and the notes with the
same effect as if such surviving entity had been named as such.

     Each Guarantor (other than any Guarantor whose Guarantee is to be released
in accordance with the terms of the Guarantee and the Indenture in connection
with any transaction complying with the provisions of "-- Limitation on Asset
Sales") will not, and we will not cause or permit any Guarantor to, consolidate
with or merge with or into any Person other than RailWorks or any other
Guarantor unless:

          (1) the entity formed by or surviving any such consolidation or merger
     (if other than the Guarantor) or to which such sale, lease, conveyance or
     other disposition shall have been made is a corporation organized and
     existing under the laws of the United States or any State thereof or the
     District of Columbia;

          (2) such entity assumes by supplemental indenture all of the
     obligations of the Guarantor on the Guarantee;

          (3) immediately after giving effect to such transaction, no Default or
     Event of Default shall have occurred and be continuing; and

          (4) immediately after giving effect to such transaction and the use of
     any net proceeds therefrom on a pro forma basis, RailWorks could satisfy
     the provisions of clause (2) of the first paragraph of this covenant.

     Any merger or consolidation of a Guarantor with and into RailWorks (with
RailWorks being the surviving entity) or another Guarantor that is a Wholly
Owned Restricted Subsidiary of RailWorks need only comply with clause (4) of the
first paragraph of this covenant.

     Limitations on Transactions with Affiliates.  (a) We will not, and will not
permit any of our Restricted Subsidiaries to, directly or indirectly, enter into
or permit to exist any transaction or series of related transactions (including,
without limitation, the purchase, sale, lease or exchange of any property or the
rendering of any service) with, or for the benefit of, any of our Affiliates,
each such transaction is referred to as an "Affiliate Transaction", other than
(x) Affiliate Transactions permitted under paragraph (b) below and (y) Affiliate
Transactions on terms that are no less favorable than those that might
reasonably have been obtained in a comparable transaction at such time on an
arm's-length basis from a Person that is not an Affiliate of RailWorks or such
Restricted Subsidiary.

     All Affiliate Transactions, and each series of related Affiliate
Transactions which are similar or part of a common plan, involving aggregate
payments or other property with a fair market value in excess of $2.0 million
shall be approved by the board of directors of RailWorks or such Restricted
Subsidiary, as the case may be, such approval to be evidenced by a Board
Resolution stating that such board of directors has determined that the
transaction complies with the foregoing provisions. If RailWorks or any of its
Restricted Subsidiaries enters into an Affiliate Transaction, or a series of
related Affiliate Transactions related to a common plan, that involves an
aggregate fair market value of more than $5.0 million, RailWorks or such
Restricted Subsidiary, as the case may be, will, prior to the consummation of
the transaction, obtain a favorable opinion as to the fairness of such
transaction or series of related transactions to RailWorks or the relevant
Restricted Subsidiary, as the case may be, from a financial point of view, from
an Independent Financial Advisor and file the same with the trustee.

     (b) The restrictions set forth in the first paragraph of this covenant
shall not apply to:

          (1) reasonable fees and compensation, including severance payments and
     compensation in the form of securities, and customary expense reimbursement
     paid to and indemnity and
                                       88
<PAGE>   94

     reimbursement provided on behalf of, officers, directors, employees or
     consultants of RailWorks or any of its RailWorks Restricted Subsidiaries as
     determined in good faith by RailWorks's board of directors or senior
     management;

          (2) transactions exclusively between or among RailWorks and any of its
     Restricted Subsidiaries or exclusively between or among such Restricted
     Subsidiaries, provided such transactions are not otherwise prohibited by
     the indenture;

          (3) transactions pursuant to or contemplated by any agreement as in
     effect as of April 7, 1999 or any amendment thereto or any replacement
     agreement so long as any such amendment or replacement agreement is not
     more disadvantageous to the holders in any material respect than the
     original agreement as in effect on April 7, 1999;

          (4) loans and advances to employees or officers of RailWorks and its
     Restricted Subsidiaries permitted by clause (4) of the definition of
     "Permitted Investments;"

          (5) Restricted Payments permitted by the indenture; and

          (6) contingent and "earn out" payments incurred in connection with any
     Asset Acquisition or otherwise, which are contingent on the performance of
     the assets or properties acquired.

     Additional Subsidiary Guarantees.  If RailWorks or any of its Restricted
Subsidiaries transfers or causes to be transferred, in one transaction or a
series of related transactions, any property to any domestic Restricted
Subsidiary that is not a Guarantor, or if RailWorks or any of its Restricted
Subsidiaries organizes, acquires or otherwise invests in another domestic
Restricted Subsidiary having total assets with a book value in excess of
$500,000, then such transferee or acquired or other Restricted Subsidiary shall:

          (1) execute and deliver to the trustee a supplemental indenture in
     form reasonably satisfactory to the trustee pursuant to which such
     Restricted Subsidiary unconditionally guarantees on a senior subordinated
     basis all of the RailWorks obligations under the notes and the indenture on
     the terms set forth in the indenture; and

          (2) deliver to the trustee an opinion of counsel that such
     supplemental indenture has been duly authorized, executed and delivered by
     such Restricted Subsidiary and constitutes a legal, valid, binding and
     enforceable obligation of such Restricted Subsidiary. Thereafter, such
     Restricted Subsidiary shall be a Guarantor for all purposes of the
     indenture.

     Conduct of Business.  RailWorks and its Restricted Subsidiaries will not
engage in any businesses which are not the same, similar or reasonably related
or ancillary to the businesses in which RailWorks and its Restricted
Subsidiaries are engaged on April 7, 1999, except to such extent as would not be
material to RailWorks and its Restricted Subsidiaries taken as a whole.

     Reports to Holders.  The indenture will provide that, whether or not
required by the rules and regulations of the SEC, so long as any notes are
outstanding, RailWorks will furnish the holders of notes:

          (1) all quarterly and annual financial information that would be
     required to be contained in a filing with the SEC on Forms 10-Q and 10-K if
     RailWorks were required to file such Forms, including a "Management's
     Discussion and Analysis of Financial Condition and Results of Operations"
     that describes the financial condition and results of operations of
     RailWorks and its consolidated Subsidiaries, showing in reasonable detail,
     either on the face of the financial statements or in the footnotes thereto
     and in Management's Discussion and Analysis of Financial Condition and
     Results of Operations, the financial condition and results of operations of
     RailWorks and its Restricted Subsidiaries separate from the financial
     condition and results of operations of the Unrestricted Subsidiaries of
     RailWorks, if any, and,

                                       89
<PAGE>   95

     with respect to the annual information only, a report thereon by
     RailWorks's certified independent accounts; and

          (2) all current reports that would be required to be filed with SEC on
     Form 8-K if RailWorks were required to file such reports, in each case
     within the time periods specified in the SEC's rules and regulations.

     In addition, following the consummation of the exchange offer contemplated
by the registration rights agreement, whether or not required by the rules and
regulations of the SEC, we will file a copy of all such information and reports
with the SEC for public availability within the time periods specified in the
SEC's rules and regulations, unless the SEC will not accept such a filing, and
make such information available to securities analysts and prospective investors
upon request. In addition, we have agreed that, for so long as any notes remain
outstanding, we will furnish to the holders and to securities analysts and
prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act.

EVENTS OF DEFAULT

     The following events are defined in the indenture as "Events of Default":

          (1) the failure to pay interest on any notes when they become due and
     payable and the default continues for a period of 30 days, whether or not
     such payment is prohibited by the subordination provisions of the
     indenture;

          (2) the failure to pay the principal on any notes, when such principal
     becomes due and payable, at maturity, upon redemption or otherwise,
     including the failure to make a payment to purchase notes tendered pursuant
     to a Change of Control Offer or a Net Proceeds Offer, whether or not such
     payment is prohibited by the subordination provisions of the indenture;

          (3) a default in the observance or performance of any other covenant
     or agreement contained in the indenture, which default continues for a
     period of 60 days after RailWorks receives written notice specifying the
     default, and demanding that such default be remedied, from the trustee or
     the holders of at least 25% of the outstanding principal amount of the
     notes (except in the case of a default with respect to the "Merger,
     Consolidation and Sale of Assets" covenant, which will constitute an Event
     of Default with such notice requirement but without such passage of time
     requirement);

          (4) the failure to pay at final maturity, after giving effect to any
     applicable grace periods and any extensions thereof, the principal amount
     of any Indebtedness of RailWorks or any Restricted Subsidiary of RailWorks
     and such failure continues for a period of 20 days or more, or the
     acceleration of the final stated maturity of any such Indebtedness, which
     acceleration is not rescinded, annulled or otherwise cured within 20 days
     of receipt by RailWorks or such Restricted Subsidiary of notice of any such
     acceleration, if the aggregate principal amount of such Indebtedness,
     whether outstanding under one or more agreements, together with the
     principal amount of any other such Indebtedness in default for failure to
     pay principal at final maturity or which has been accelerated, aggregates
     $10.0 million or more at any time;

          (5) one or more judgments in an aggregate amount in excess of $10.0
     million shall have been rendered against RailWorks or any of its Restricted
     Subsidiaries and such judgments remain undischarged, unpaid or unstayed for
     a period of 60 days after such judgment or judgments become final and
     non-appealable;

          (6) certain events of bankruptcy affecting RailWorks or any of its
     Significant Subsidiaries; or

          (7) any Guarantee of a Significant Subsidiary ceases to be in full
     force and effect or any Guarantee of a Significant Subsidiary is declared
     to be null and void and unenforceable or
                                       90
<PAGE>   96

     any Guarantee of a Significant Subsidiary is found to be invalid or any
     Guarantor that is a Significant Subsidiary denies its liability under its
     Guarantee (other than by reason of release of a Guarantor in accordance
     with the terms of the indenture) and such condition has continued for a
     period of 30 days after written notice of such failure requiring the
     Guarantor and RailWorks to remedy the same has been given (x) to RailWorks
     by the trustee or (y) to RailWorks and the trustee by the holders of 25% in
     aggregate principal amount of the notes then outstanding.

     If an Event of Default, other than an Event of Default specified in clause
(6) above with respect to RailWorks, shall occur and be continuing, the trustee
or the holders of at least 25% in principal amount of outstanding notes may
declare the principal of and accrued interest on all the notes to be due and
payable by notice in writing to RailWorks and the trustee specifying the
respective Event of Default and that it is a "notice of acceleration", such
notice being an "Acceleration Notice", and the same:

          (1) shall become immediately due and payable; or

          (2) if there are any amounts outstanding under the Credit Agreement,
     shall become immediately due and payable upon the first to occur of an
     acceleration under the Credit Agreement or 5 business days after receipt by
     RailWorks and the Representative under the Credit Agreement of such
     Acceleration Notice but only if such Event of Default is then continuing.
     If an Event of Default specified in clause (6) above with respect to
     RailWorks occurs and is continuing, then all unpaid principal of, and
     premium, if any, and accrued and unpaid interest on all of the outstanding
     notes shall ipso facto become and be immediately due and payable without
     any declaration or other act on the part of the trustee or any holder.

     The indenture provides that, at any time after a declaration of
acceleration with respect to the notes as described in the preceding paragraph,
the holders of a majority in principal amount of the notes may rescind and
cancel such declaration and its consequences:

          (1) if the rescission would not conflict with any judgment or decree;

          (2) if all existing Events of Default have been cured or waived except
     nonpayment of principal or interest that has become due solely because of
     the acceleration;

          (3) to the extent the payment of such interest is lawful, interest on
     overdue installments of interest and overdue principal, which has become
     due otherwise than by such declaration of acceleration, has been paid;

          (4) if RailWorks has paid the trustee its reasonable compensation and
     reimbursed the trustee for its expenses, disbursements and advances; and

          (5) in the event of the cure or waiver of an Event of Default of the
     type described in clause (6) of the description above of Events of Default,
     the trustee shall have received an officers' certificate and an opinion of
     counsel that such Event of Default has been cured or waived. No such
     rescission shall affect any subsequent Default or impair any right
     consequent to a Default.

     The holders of not less than a majority in principal amount of the notes
may waive any existing Default or Event of Default under the indenture, and its
consequences, except a default in the payment of the principal of or interest on
any notes.

     Holders of the notes may not enforce the indenture or the notes except as
provided in the indenture and under the Trust Indenture Act. Subject to the
provisions of the indenture relating to the duties of the trustee, the trustee
is under no obligation to exercise any of its rights or powers under the
indenture at the request, order or direction of any of the holders, unless such
holders have offered reasonable indemnity to the trustee. Subject to all
provisions of the indenture and applicable law, the holders of a majority in
aggregate principal amount of the then

                                       91
<PAGE>   97

outstanding notes have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the trustee or exercising
any trust or power conferred on the trustee.

     Under the indenture, we are required to provide an officers' certificate to
the trustee promptly upon any such officer's obtaining knowledge of any Default
or Event of Default, provided that such officers shall provide such
certification at least annually whether or not they know of any Default or Event
of Default, that has occurred and, if applicable, describe such Default or Event
of Default and the status thereof.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     We may, at our option and at any time, elect to have our obligations and
the obligations of the Guarantors discharged with respect to the outstanding
notes, such discharge is called "Legal Defeasance". Legal Defeasance means that
RailWorks and, if it so elects, the Guarantors, shall be deemed to have paid and
discharged the entire indebtedness represented by the outstanding notes, except
for:

          (1) the rights of holders to receive payments in respect of the
     principal of, premium, if any, and interest on the notes when those
     payments are due;

          (2) our obligations with respect to the notes concerning issuing
     temporary notes, registration of notes, mutilated, destroyed, lost or
     stolen notes and the maintenance of an office or agency for payments;

          (3) the rights, powers, trust, duties and immunities of the trustee
     and our related obligations; and

          (4) the Legal Defeasance provisions of the indenture.

     In addition, we may, at our option and at any time, elect to have our
obligations and the obligations of the Guarantors released with respect to
certain covenants that are described in the indenture, such release is called
"Covenant Defeasance", and thereafter any omission to comply with those
obligations shall not constitute a Default or Event of Default with respect to
the notes. In the event Covenant Defeasance occurs, certain events, described
under "Events of Default" but not including non-payment, bankruptcy,
receivership, reorganization and insolvency events, will no longer constitute an
Event of Default with respect to the notes. Concurrently with any Legal
Defeasance or Covenant Defeasance, we may, at our further option, cause to be
terminated, as of the date on which such Legal Defeasance or Covenant Defeasance
occurs, all of the obligations under any or all of the Guarantees, if any, then
existing. In order to exercise such option regarding a Guarantee, we will
provide the trustee with written notice of our desire to terminate that
Guarantee prior to the delivery of the opinion of counsel referred to in clause
(2) or (3), as applicable, of the next succeeding paragraph.

     In order to exercise either Legal Defeasance or Covenant Defeasance:

          (1) we must irrevocably deposit with the trustee, in trust, for the
     benefit of the holders, cash in U.S. dollars, non-callable U.S. government
     obligations, or a combination thereof, in amounts as will be sufficient, in
     the opinion of a nationally recognized firm of independent public
     accountants, to pay the principal of, premium, if any, and interest on the
     notes on the stated date for their payment or on the applicable redemption
     date, as the case may be;

          (2) in the case of Legal Defeasance, we must deliver to the trustee an
     opinion of counsel in the United States reasonably acceptable to the
     trustee confirming that:

             (a) we have received from, or there has been published by, the
        Internal Revenue Service a ruling; or

                                       92
<PAGE>   98

             (b) since the date of the indenture, there has been a change in the
        applicable federal income tax law, in either case to the effect that,
        and based thereon such opinion of counsel shall confirm that, the
        holders will not recognize income, gain or loss for federal income tax
        purposes as a result of such Legal Defeasance and will be subject to
        federal income tax on the same amounts, in the same manner and at the
        same times as would have been the case if such Legal Defeasance had not
        occurred;

          (3) in the case of Covenant Defeasance, we must deliver to the trustee
     an opinion of counsel in the United States reasonably acceptable to the
     trustee confirming that the holders will not recognize income, gain or loss
     for federal income tax purposes as a result of such Covenant Defeasance and
     will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such Covenant
     Defeasance had not occurred;

          (4) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or an Event of
     Default resulting from the borrowing of funds to be applied to such deposit
     and the grant of any Lien securing such borrowing) or insofar as Events of
     Default from bankruptcy or insolvency events are concerned, at any time in
     the period ending on the 91st day after the date of deposit;

          (5) such Legal Defeasance or Covenant Defeasance shall not result in a
     breach or violation of, or constitute a default under the indenture (other
     than a Default or an Event of Default resulting from the borrowing of funds
     to be applied to such deposit and the grant of any Lien securing such
     borrowing) or any other material agreement or instrument to which we or any
     of our subsidiaries is a party or by which we or any of our subsidiaries is
     bound;

          (6) we must deliver to the trustee an officers' certificate stating
     that we did not make the deposit with the intent of preferring the holders
     over any of our other creditors or with the intent of defeating, hindering,
     delaying or defrauding any of our other creditors or others;

          (7) we must deliver to the trustee an officers' certificate and an
     opinion of counsel, each stating that all conditions precedent provided for
     or relating to the Legal Defeasance or the Covenant Defeasance have been
     complied with;

          (8) we must deliver to the trustee an opinion of counsel to the effect
     that, subject to customary assumptions and exclusions:

             (a) the trust funds will not be subject to any rights of holders of
        Senior Debt, including, without limitation, those arising under the
        indenture; and

             (b) assuming no intervening bankruptcy of RailWorks between the
        date of deposit and the 91st day following the date of deposit and that
        no holder is an insider of RailWorks, after the 91st day following the
        date of deposit, the trust funds will not be subject to the effect of
        any applicable bankruptcy, insolvency, reorganization or similar laws
        affecting creditors' rights generally; and

          (9) certain other customary conditions precedent are satisfied.

     Despite the above, the opinion of counsel required by clause (2) above with
respect to a Legal Defeasance need not be delivered if all notes not theretofore
delivered to the trustee for cancellation (1) have become due and payable, (2)
will become due and payable on the maturity date within one year or (3) are to
be called for redemption within one year under arrangements satisfactory to the
trustee for the giving of notice of redemption by the trustee in our name, and
at our expense.

        premium, if any, and interest on the notes to the date of deposit
        together with irrevocable instructions from us directing the trustee to
        apply the funds to the payment at maturity or redemption;

          (2) we have paid all other sums payable under the indenture by us; and

of the holders, may amend the indenture for certain specified purposes,
including:

     indenture so long as such change does not adversely affect the rights of
     the holders in any material respect; or

     provisions of the indenture, including in connection with a sale of all of
     the Capital Stock or all or substantially all of the assets of the

     Other modifications and amendments of the indenture may be made with the
consent of the holders of a majority in principal amount of the then outstanding
notes issued under the indenture, including without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer

     payment, or permitting holders of a majority in principal amount of notes
     to waive Defaults or Events of Default;

GOVERNING LAW

     The indenture provides that it, the notes and the Guarantees are governed
by, and construed in accordance with, the laws of the State of New York but
without giving effect to applicable principles of conflicts of law to the extent
that the application of the law of another jurisdiction would be required by New
York State law.

THE TRUSTEE

     The indenture provides that, except during the continuance of an Event of
Default, the trustee will perform only such duties as are specifically set forth
in the indenture. During the existence of an Event of Default, the trustee will
exercise such rights and powers vested in it by the indenture, and use the same
degree of care and skill in its exercise as a prudent person would exercise or
use under the circumstances in the conduct of such person's own affairs.

     The indenture and the provisions of the Trust Indenture Act contain certain
limitations on the rights of the trustee, should it become a creditor of
RailWorks, to obtain payments of claims in certain cases or to realize on
certain property received in respect of any such claim as security
                                       95
<PAGE>   101

or otherwise. Subject to the Trust Indenture Act, the trustee will be permitted
to engage in other transactions; provided that if the trustee acquires any
conflicting interest as described in the Trust Indenture Act, it must eliminate
such conflict or resign.

     "Consolidated Fixed Charge Coverage Ratio" means, with respect to any
Person, the ratio of (a) Consolidated EBITDA of such Person during the four full

transaction giving rise to the need to calculate the Consolidated Fixed Charge
Coverage Ratio for which financial statements are available, that date being the
"Transaction Date", to (b) Consolidated Fixed Charges of such Person for the
Four Quarter Period. In addition to and without limitation of the foregoing, for
purposes of this definition, "Consolidated EBITDA" and "Consolidated Fixed
Charges" shall be calculated after giving effect on a pro forma basis for the
period of such calculation to:

          (1) the incurrence, repayment or retirement of any Indebtedness of
     such Person or any of its Restricted Subsidiaries (and the application of

     Quarter Period and on or prior to the Transaction

                                       98
<PAGE>   104

     Date, as if such incurrence, repayment or retirement, as the case may be
     (and the application of the proceeds thereof), occurred on the first day of
     the Four Quarter Period; and

          (2) any Asset Sales or Asset Acquisitions (including, without
     limitation, any Asset Acquisition giving rise to the need to make such
     calculation as a result of such Person or one of its Restricted
     Subsidiaries (including any Person who becomes a Restricted Subsidiary as a
     result of the Asset Acquisition) incurring, assuming or otherwise being
     liable for Acquired Indebtedness and also including any Consolidated EBITDA
     (including any pro forma expense and cost reductions calculated on a basis
     consistent with Regulation S-X of the Exchange Act) attributable to the
     assets which are the subject of the Asset Acquisition or asset sale or
     other disposition during the Four Quarter Period) occurring during the Four
     Quarter Period or at any time subsequent to the last day of the Four
     Quarter Period and on or prior to the Transaction Date, as if such Asset
     Sale or Asset Acquisition, including the incurrence, assumption or
     liability for any such Acquired Indebtedness, occurred on the first day of
     the Four Quarter Period. If such Person or any of its Restricted
     Subsidiaries directly or indirectly guarantees Indebtedness of a third
     Person, the preceding sentence shall give effect to the incurrence of such
     guaranteed Indebtedness as if such Person or any Restricted Subsidiary of
     such Person had directly incurred or otherwise assumed such guaranteed
     Indebtedness. For purposes of calculating the Consolidated Fixed Charge
     Coverage Ratio only, clause (c) of the definition of Asset Sale shall not
     be given effect to the extent it relates to a dividend or distribution in
     respect of shares of the RailWorks Capital Stock consisting of shares of
     Capital Stock of a Restricted Subsidiary of RailWorks.

     Furthermore, in calculating "Consolidated Fixed Charges" for purposes of
determining the denominator (but not the numerator) of this "Consolidated Fixed
Charge Coverage Ratio":

          (1) interest on outstanding Indebtedness determined on a fluctuating
     basis as of the Transaction Date and which will continue to be so
     determined thereafter shall be deemed to have accrued at a fixed rate per
     annum equal to the rate of interest on such Indebtedness in effect on the
     Transaction Date;

          (2) notwithstanding clause (1) above, interest on Indebtedness
     determined on a fluctuating basis, to the extent such interest is covered
     by agreements relating to Interest Swap Obligations, shall be deemed to
     accrue at the rate per annum resulting after giving effect to the operation
     of such agreements; and

          (3) if interest on any Indebtedness actually incurred on the
     Transaction Date may optionally be determined at an interest rate based
     upon a factor of a prime or similar rate, a eurocurrency interbank offered
     rate; or other rates, then the interest rate in effect on the Transaction
     Date will be deemed to have been in effect during the Four Quarter Period.

     "Consolidated Fixed Charges" means, with respect to any Person for any
period, the sum, without duplication, of:

          (1) Consolidated Interest Expense; plus

          (2) the product of (x) the amount of all dividend payments on any
     series of Preferred Stock of such Person and, to the extent permitted under
     the Indenture, its Restricted Subsidiaries (other than dividends paid in
     Qualified Capital Stock) paid or accrued during such period times (y) a
     fraction, the numerator of which is one and the denominator of which is one
     minus the then current effective consolidated federal, state and local tax
     rate of such Person, expressed as a decimal, provided that Consolidated
     Fixed Charges shall not include (x) gain or loss from the extinguishment of
     debt, including, without limitation, write-off of debt issuance costs,
     commissions, fees and expenses, (y) amortization of customary debt issuance
     costs, commissions, fees and expenses or (z) customary commitment,
     administrative and transaction fees or charges.

period, the sum of, without duplication:

          (1) the aggregate of the interest expense of such Person and its
     Restricted Subsidiaries for such period determined on a consolidated basis
     in accordance with GAAP, including without limitation: (a) any amortization
     of debt discount and amortization or write-off deferred financing costs;
     (b) the net costs under Interest Swap Obligations; (c) all capitalized
     interest; and (d) the interest portion of any deferred payment obligation;
     and

          (2) the interest component of Capitalized Lease Obligations paid or
     accrued by such Person and its Restricted Subsidiaries during such period
     as determined on a consolidated basis in accordance with GAAP.

     "Consolidated Net Income" means, with respect to any Person, for any
period, the aggregate net income (or loss) of such Person and its Restricted
Subsidiaries for such period on a consolidated basis, determined in accordance
with GAAP; provided that there shall be excluded therefrom:

          (1) after-tax gains or losses (to the extent such losses are non-cash
     losses) from Asset Sales (without regard to the $1,000,000 limitation set
     forth in the definition thereof) or abandonments or reserves relating
     thereto;

          (2) after-tax items classified as extraordinary or nonrecurring gains
     or losses (to the extent such losses are non-cash losses);

          (3) solely for purposes of calculating Consolidated Net Income for the
     covenant described under "Limitation on Restricted Payments," the net
     income of any Person acquired in a "pooling of interests" transaction
     accrued prior to the date it becomes a Restricted Subsidiary of the
     referent Person or is merged or consolidated with the referent Person or
     any Restricted Subsidiary of the referent Person;

          (4) the net income (but not loss) of any Restricted Subsidiary of the
     referent Person to the extent that the declaration of dividends or similar

     a contract, operation of law or otherwise, except to the extent that such
     net income is actually paid to the Company or one of its Restricted
     Subsidiaries through dividends, loans or otherwise;

          (5) the net income of any Person, other than a Restricted Subsidiary
     of the referent Person, except to the extent of cash dividends or
     distributions paid to the referent Person or to a Wholly Owned Restricted
     Subsidiary of the referent Person by such Person;

          (6) any restoration to income of any contingency reserve, except to
     the extent that provision for such reserve was made out of Consolidated Net
     Income accrued at any time following April 7, 1999;

          (7) income or loss attributable to discontinued operations (including,
     without limitation, operations disposed of during such period whether or
     not such operations were classified as discontinued); and

a minority interest in Guarantors, minus (b) any cash payment with respect to
which a charge or reserve referred to in clause (a) was taken in a prior period,

             (b) such Liens do not extend to or cover any property or assets of
        RailWorks or of any of its Restricted Subsidiaries other than the
        property or assets that secured the Acquired Indebtedness prior to the
        time such Indebtedness became Acquired Indebtedness of RailWorks or a
        Restricted Subsidiary of RailWorks and are no more favorable to the
        lienholders than those securing the Acquired Indebtedness prior to the
        incurrence of such Acquired Indebtedness by RailWorks or a Restricted
        Subsidiary of RailWorks; and

          (15) Liens not permitted by clauses (1) through (14) that are incurred

not be senior in right of payment to the notes. Without limiting the generality
of the foregoing, "Senior Debt" shall also include the principal of, premium, if
any, interest (including any interest accruing subsequent to the filing of a

     received an officers' certificate of RailWorks to the effect that the
     incurrence of such Indebtedness does not (or, in the case of revolving
     credit indebtedness, that the incurrence of the entire committed amount
     thereof at the date on which the initial borrowing thereunder is made would
     not) violate such provisions of the indenture);

          (7) Indebtedness which, when incurred and without respect to any
     election under Section 1111(b) of Title 11, United States Code, is without
     recourse to RailWorks; and

          (8) any Indebtedness which is, by its express terms, subordinated in
     right of payment to any other Indebtedness of RailWorks.

     "Significant Subsidiary", with respect to any Person, means any Restricted

any newly acquired or newly formed Subsidiary) to be an Unrestricted Subsidiary
unless such Subsidiary owns any Capital Stock of, or owns or holds any Lien on
any property of, RailWorks or any other Subsidiary of RailWorks that is not a

     to any of the assets of RailWorks or any of its Restricted Subsidiaries.

     The RailWorks board of directors may designate any Unrestricted Subsidiary
to be a Restricted Subsidiary only if:

          (1) immediately after giving effect to such designation, RailWorks is
     able to incur at least $1.00 of additional Indebtedness (other than
     Permitted Indebtedness) in compliance with the "Limitation on Incurrence of
     Additional Indebtedness" covenant; and

          (2) immediately before and immediately after giving effect to such

                      EXCHANGE OFFER; REGISTRATION RIGHTS

     As part of the sale of the old notes to First Union Capital Markets
pursuant to the purchase agreement, dated September 23, 1999, among RailWorks
and the initial purchaser, the holder of the old notes became entitled to the
benefits of the registration rights agreement, dated as of September 30, 1999 by
and among RailWorks and the initial purchaser.

     Under the registration rights agreement, we have agreed:

     - to file a registration statement with the SEC with respect to a
       registered offer to exchange the old notes for new 11 1/2% Senior
       Subordinated Notes due 2009, having terms substantially identical in all
       material respects to the old notes, except that the new notes will not
       contain transfer restrictions, by November 13, 1999;


     - to use our reasonable best efforts to cause the registration statement to
       become effective under the Securities Act by January 28, 2000;


     - to offer the new notes and the related guarantees in exchange for
       surrender of the old notes following the effective date of the
       registration statement; and

     - to use our reasonable best efforts to keep the exchange offer open for at
       least 30 days, or longer if required by applicable law, after the date
       that the notice of the exchange offer is mailed to the holders of the old
       notes.


     The exchange offer being made hereby, if consummated within the required
time periods, will satisfy our obligations under the registration rights
agreement. We understand that there are approximately 15 record holders of old
notes. For each old note validly surrendered to us pursuant to the exchange
offer and not validly withdrawn, the holder will receive a new note having a
principal amount equal to that of the surrendered old note. Interest on each old
note will accrue (1) from the later of (A) the last interest payment date on
which interest was paid on the old note surrendered in exchange for the new note
or, (B) if the old note is surrendered for exchange on a date in a period that
includes the record date for an interest payment date to occur on or after the
date of the exchange and as to which interest will be paid, the date of such
interest payment date, or (2) if no interest has been paid on the old notes,
from September 30, 1999.


     Under existing interpretations of the SEC contained in several no-action
letters to third parties, we believe that the new notes and the related
guarantees will be freely transferable by the holders, other than affiliates of
RailWorks, after the exchange offer without further registration under the
Securities Act; provided, however, that if you want to exchange your old notes
for new notes, you will be required to represent:

          (1) you have full power and authority to tender, sell, assign and
     transfer the old notes surrendered;

          (2) we will acquire good title to the old notes being surrendered,
     free and clear of all security interests, liens, restrictions, charges,
     encumbrances, conditional sale agreements or other obligations relating to
     their sale or transfer, and not subject to any adverse claim when we accept
     the old notes;

          (3) you are acquiring the new notes in the ordinary course of your
     business;

          (4) you are not engaging and do not intend to engage in a distribution
     of the new notes;

          (5) you have no arrangement or understanding with any person to
     participate in the distribution of the new notes;

          (6) you acknowledge and agree that if you are a broker-dealer
     registered under the Exchange Act or you are participating in the exchange
     offer for the purpose of distributing
                                       112
<PAGE>   118

     the new notes, you must comply with the registration and prospectus
     delivery requirements of the Securities Act in connection with a secondary
     resale of the new notes, and that you cannot rely on the position of the
     SEC's staff set forth in their no-action letters;

          (7) you understand that a secondary resale transaction described above
     and any resales of new notes obtained by you in exchange for old notes
     acquired by you directly from us should be covered by an effective
     registration statement containing the selling security holder information
     required by Item 507 or 508, as applicable, of Regulation S-K of the SEC;
     and

          (8) you are not an "affiliate", as defined in Rule 405 under the
     Securities Act, of RailWorks or any subsidiary guarantor, or, if you are an
     "affiliate," that you will comply with the registration and prospectus
     delivery requirements of the Securities Act to the extent applicable.

     We agree to make available, during the period required by the Securities
Act, a prospectus meeting the requirements of the Securities Act for use by
Participating Broker-Dealers and other persons, if any, with similar prospectus
delivery requirements for use in connection with any resale of new notes.


     If (1) because of any change in law or in currently prevailing
interpretations of the staff of the SEC, we are not permitted to effect an
exchange offer, (2) we do not complete the exchange offer by February 27, 2000,
(3) under certain circumstances, some holders of unregistered new notes so
request, or (4) in the case of any holder that participates in the exchange
offer, that holder does not receive new notes on the date of the exchange that
may be sold without restriction under state and federal securities laws, other
than due solely to the status of that holder as an affiliate of RailWorks or
within the meaning of the Securities Act, then in each case, we will


     - promptly deliver to the holders and the trustee written notice of one of
       these changes and

     - at our sole expense, file a shelf registration statement covering resales
       of the old notes;


     - use our reasonable best efforts to keep the shelf registration statement
       effective until the earlier of September 30, 2001 or such time as all of
       the applicable old notes have been sold under the shelf registration
       statement.


     In the event that we file a shelf registration statement, we will provide
each holder with copies of the prospectus that is a part of the shelf
registration statement, notify each holder when the shelf registration statement
for the notes has become effective, and take some other actions that are
required to permit unrestricted resales of the notes. A holder that sells notes
pursuant to the shelf registration statement will be required to be named as a
selling security holder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
Securities Act in connection with such sales and will be bound by the provisions
of the registration rights agreement that are applicable to that kind of holder,
including certain indemnification rights and obligations.

     If we fail to comply with the above provisions or if the exchange offer
registration statement or the shelf registration statement fails to become
effective, then, as liquidated damages, we will pay "additional interest" on the
notes as follows:

          (1) if (A) neither the exchange offer registration statement nor the
     shelf registration statement is filed with the SEC on or prior to the
     applicable filing date or (B) despite the fact that we have consummated or
     will consummate an exchange offer, we are required to file a shelf
     registration statement and we do not file the shelf registration statement
     on or prior to the date required by the registration rights agreement, then
     commencing on the day after either such required filing date, additional
     interest will accrue on the principal amount of the notes at a yearly rate
     of 0.25% for the first 90 days immediately following each such
                                       113
<PAGE>   119

     filing date; the additional interest rate will increase by an additional
     0.25% per annum at the beginning of each subsequent 90-day period; or


          (2) if (A) neither the exchange offer registration statement nor a
     shelf registration statement is declared effective by the SEC on or prior
     to 120 days after the applicable filing date set forth in the registration
     rights agreement or (B) despite the fact that we have consummated or will
     consummate an exchange offer, we are required to file a shelf registration
     statement and the SEC does not declare the shelf registration statement
     effective on or prior to the 120th day following the date the shelf
     registration statement was filed, then, commencing on the day after either
     required effective date, additional interest will accrue on the principal
     amount of the note at a yearly rate of 0.25% for the first 90 days
     immediately following that required effective date; the additional interest
     rate will increase by an additional 0.25% per annum at the beginning of
     each subsequent 90-day period; or



          (3) if (A) we have not exchanged new notes for all old notes validly
     surrendered in accordance with the terms of the exchange offer on or prior
     to February 27, 2000, or (B) if applicable, the shelf registration
     statement has been declared effective and the shelf registration statement
     ceases to be effective at any time prior to September 30, 2001, other than
     after such time as all notes have been disposed of under the shelf
     registration statement, then additional interest will accrue on the
     principal amount of the notes at a yearly rate of 0.25% for the first 90
     days commencing on (x) the 36th day after the effective date, in the case
     of (A) above, or (y) the day the shelf registration statement ceases to be
     effective, in the case of (B) above; the additional interest rate will
     increase by an additional 0.25% per annum at the beginning of each
     subsequent 90-day period;


provided, however, that the additional interest rate on the notes may not accrue
under more than one of the foregoing clauses (1) -- (3) at any one time and at
no time shall the aggregate amount of additional interest accruing exceed in the
aggregate 1.5% per year; provided, further, however, that (c) upon the filing of
the exchange offer registration statement or a shelf registration statement, in
the case of clause (1) above, (d) upon the effectiveness of the exchange offer
registration statement or a shelf registration statement, in the case of clause
(2) above, or (e) upon the exchange of new notes for all old notes surrendered,
in the case of clause (3)(A) above, or upon the effectiveness of the shelf
registration statement that had ceased to remain effective, in the case of
clause (3)(B) above, additional interest on the notes as a result of such
clause, or the relevant subclause of that clause, as the case may be, shall
cease to accrue.

     Any amounts of additional interest due pursuant to clause (1), (2) or (3)
above will be payable in cash on the same original interest payment dates as the
notes.

                         BOOK-ENTRY; DELIVERY AND FORM

     The new notes initially will be represented by one or more permanent global
certificates in definitive, fully registered form (the "Global notes"). The
Global notes will be deposited upon issuance with DTC and registered in the name
of a nominee of DTC.

THE GLOBAL NOTE

     We expect that pursuant to procedures established by DTC (1) upon the
issuance of the Global notes, DTC or its custodian will credit, on its internal
system, the principal amount at maturity of the individual beneficial interests
represented by such Global notes to the respective accounts of persons who have
accounts with such depositary and (2) ownership of beneficial interests in the
Global notes will be shown on, and the transfer of such ownership will be
effected only through, records maintained by DTC or its nominee (with respect to
interests of participants) and the records of participants (with respect to
interests of persons other than participants). Ownership of beneficial interests
in the Global notes will be limited to persons who have accounts with DTC
("participants") or persons who hold interests through participants. Holders may
hold their interests in the Global notes directly through DTC if they are
participants in DTC's system, or indirectly through organizations that are
participants in such system.

     So long as DTC, or its nominee, is the registered owner or holder of the
new notes, DTC or such nominee, as the case may be, will be considered the sole
owner or holder of the new notes represented by such Global notes for all
purposes under the indenture. No beneficial owner of an interest in the Global
notes will be able to transfer that interest except in accordance with DTC's
procedures, in addition to those provided for under the indenture with respect
to the new notes.

     Payments of the principal of, premium, if any, interest, including
additional interest, on, the Global notes will be made to DTC or its nominee as
the registered owner of the Global notes. None of RailWorks, the trustee or any
paying agent will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in the Global notes or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest.

     We expect that DTC or its nominee, upon receipt of any payment of
principal, premium, if any, interest, including additional interest, on the
Global notes, will credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of the Global notes as shown on the records of DTC or its nominee. We also
expect that payments by participants to owners of beneficial interests in the
Global notes held through such participants will be governed by standing
instructions and customary practice, as is now the case with securities held for
the accounts of customers registered in the names of nominees for such
customers. Such payments will be the responsibility of such participants.

     Transfers between participants in DTC will be effected in the ordinary way
through DTC's same-day funds system in accordance with DTC rules and will be
settled in same day funds. If a holder requires physical delivery of a
certificated security for any reason, including to sell new notes to persons in
states that require physical delivery of the new notes, or to pledge such
securities, such holder must transfer its interest in a Global note, in
accordance with the normal procedures of DTC and with the procedures set forth
in the indenture.

     DTC has advised us that it will take any action permitted to be taken by a
holder of new notes, including the presentation of new notes for exchange as
described below, only at the direction of one or more participants to whose
account the DTC interests in the Global notes are credited and only in respect
of such portion of the aggregate principal amount of notes as to which such
participant or participants has or have given such direction. However, if there
is an

                                       115
<PAGE>   121

Event of Default under the Indenture, DTC will exchange the Global notes for
certificated securities, which it will distribute to its participants.

     DTC has advised us as follows: DTC is a limited purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "Clearing Agency" registered pursuant to the provisions of
Section 17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book-entry changes in
accounts of its participants, thereby eliminating the need for physical movement
of certificates. Participants include securities brokers and dealers, banks,
trust companies and clearing corporations and certain other organizations.
Indirect access to the DTC system is available to others such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global note among participants of DTC, it is under
no obligation to perform such procedures, and such procedures may be
discontinued at any time. Neither RailWorks nor the trustee will have any
responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.

CERTIFICATED SECURITIES

     Certificated securities will be issued in exchange for beneficial interests
in the Global notes (1) if requested by a holder of such interests or (2) if DTC
is at any time unwilling or unable to continue as a depositary for the Global
notes and a successor depositary is not appointed by RailWorks within 90 days.

                              PLAN OF DISTRIBUTION


     We are not using any underwriters for this exchange offer. We are also
bearing the expenses of the exchange, which we expect will be approximately
$75,000.


     This prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of any new notes
received in exchange for old notes acquired by such broker-dealer as a result of
market-making or other trading activities. Each such broker-dealer that receives
new notes for its own account in exchange for such old notes pursuant to the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of such new notes. We have agreed that for a period of up to 180
days after the registration statement is declared effective, we will make this
prospectus, as amended or supplemented, available to any such broker-dealer that
requests copies of this prospectus in the letter of transmittal for use in
connection with any such resale.

     We will not receive any proceeds from any sale of new notes by
broker-dealers or any other persons. New notes received by broker-dealers for
their own account pursuant to the exchange offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions or through the writing of options on the exchange notes, or a
combination of such methods of resale, at market prices prevailing at the time
of resale or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer and/or the
purchasers of any such exchange notes. Any broker-dealer that resells new notes
that were received by it for its own account pursuant to the exchange offer in
exchange for old notes acquired by such broker-dealer as a result of
market-making or other trading activities and any broker-dealer that
participates in a distribution of such new notes may

                                       116

be deemed to be an "underwriter" within the meaning of the Securities Act. Any
profit on these resales of new notes and any commissions or concessions received
by any persons may be deemed to be underwriting compensation under the
Securities Act. The letter of transmittal states that by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

     We have agreed to pay all expenses incident to our performance of, or
compliance with, the registration rights agreement and will indemnify the
holders of old notes, including any broker-dealers, and certain parties related
to these holders, against various liabilities, including liabilities under the
Securities Act.

                CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS

     THIS SUMMARY IS OF A GENERAL NATURE AND IS INCLUDED HEREIN SOLELY FOR
INFORMATIONAL PURPOSES. IT IS NOT INTENDED TO BE, NOR SHOULD IT BE CONSTRUED AS
BEING, LEGAL OR TAX ADVICE. WE MAKE NO REPRESENTATION WITH RESPECT TO THE
CONSEQUENCES TO ANY HOLDER OF THE NOTES. YOU SHOULD CONSULT YOUR OWN TAX
ADVISORS WITH RESPECT TO YOUR PARTICULAR CIRCUMSTANCES.

     The following discussion is a summary of certain United States federal
income tax considerations relevant to the exchange of old notes for new notes
pursuant to the exchange offer. The summary is based upon current provisions of
the Internal Revenue Code of 1986, as amended, judicial decisions, and
administrative interpretations, all of which are subject to change at any time
by legislative, judicial or administrative action. Any such changes may be
applied retroactively in a manner that could adversely affect a holder of the
notes. There can be no complete assurance that the Internal Revenue Service will
not challenge the conclusions stated below, and no ruling from the Internal
Revenue Service has been or will be sought on any of the matters discussed
below.

     The following discussion does not purport to be a complete analysis of all
the potential federal income tax consequences of exchanging old notes for new
notes, and, without limiting the generality of the foregoing, this summary does
not address the effect of any special rules applicable to certain types of
holders, including dealers in securities, insurance companies, financial
institutions, tax-exempt entities, persons owning notes through partnerships or
other pass-through entities, former citizens or residents of the United States
and persons who hold notes as part of a straddle, hedge, or conversion
transaction. In addition, this discussion is limited to holders who hold the
notes as capital assets within the meaning of Section 1221 of the Internal
Revenue Code. This discussion does not address the effect of any state, local,
or foreign tax laws.

     The exchange of old notes for new notes pursuant to the exchange offer will
not be treated as an "exchange" for federal income tax purposes because the new
notes do not differ materially in kind or extent from the old notes.
Accordingly, (i) holders will not recognize taxable gain or loss upon the
receipt of new notes in exchange for old notes in the exchange offer, (ii) the
holding period for a new note received in the exchange offer will include the
holding period of the old note surrendered in exchange for the new note, and
(iii) the adjusted tax basis of a new note immediately after the exchange will
be the same as the adjusted tax basis of the old note surrendered in exchange
for the new note.

     We recommend that you consult your own tax advisor as to the particular
consequences of exchanging your old notes for new notes, including the
applicability and effect of any state, local or foreign tax laws.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933. You can find discussions containing
forward-looking statements in the "Prospectus Summary," the "Management's
Discussion and Analysis of Financial Condition and Results of Operation,"
"Business  -- Competitive Strengths," "Business  -- Strategy" and "Business
 -- Competition" sections, as well as within this prospectus generally. We use
the words "believes," "anticipates," "expects," "estimates," "plans," "intends"
and similar expressions so as to identify forward-looking statements. All
forward-looking statements involve substantial risks and uncertainties. There
may be events in the future that we are not accurately able to predict, or over
which we have no control. Some factors that may cause actual results to differ
from projected results are:

     - absence of a combined operating history of the operating companies and
       difficulties in integrating their operations;

     - unanticipated difficulties or delays in implementing our acquisition
       program;

     - cyclicality in the demand for rail system services and products;

     - availability of capital, including our ability to service or refinance
       indebtedness;

     - an unanticipated decrease in public sector contracts and funding;

     - changes in our relationships with major customers;

     - effects of changes in general economic conditions;

     - actions by competitors;

     - ability to retain qualified personnel; and

     - unanticipated costs, difficulties or delays in implementing our Year 2000
       compliance program.

     Forward-looking statements include, without limitation, our expectations
and estimates as to development of our services and products and expansion of
our customer base, future financial performance, including growth in revenues
and earnings and the effect on our finances of new acquisitions, cash flows from
operations, acquisitions, capital expenditures, the availability of funds from
credit facilities, the sale of securities and the cost and timely implementation
of our Year 2000 compliance modifications.

     Consequently, you should regard forward-looking statements only as our
current plans, estimates and beliefs. We do not promise to notify you if we
learn that our assumptions or projections are wrong for any reason. Before you
decide to exchange your notes, you should be aware that the factors we discuss
in the "Risk Factors" section and elsewhere in this prospectus could cause our
actual results to differ from what we have stated in any forward-looking
statements.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To RailWorks Corporation:

     We have audited the accompanying consolidated balance sheets of RailWorks
Corporation (a Delaware corporation) and Subsidiaries and its predecessor entity
(the "Company"), as of December 31, 1998 and 1997 and the related consolidated
statements of operations, stockholders' equity and cash flows for the three
years in the period ended December 31, 1998. 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 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 are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and the disclosures in the financial statements. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the Company
as of December 31, 1998 and 1997 and the results of its operations and its cash
flows for the three years in the period ended December 31, 1998 in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

     RailWorks Corporation, a Delaware corporation, ("RailWorks" or the
"Company"), was formed in March 1998 to acquire, integrate and facilitate the
growth of similar and complementary companies in the rail system services and
products industry.

     On July 29, 1998, RailWorks announced the initial public offering ("IPO")
of 5,000,000 shares of its common stock at a price of $12.00 per share. The
initial public offering was consummated on August 4, 1998. The capital raised by
this offering was $55,800,000 net of underwriting discounts.

     Concurrent with the consummation of the IPO, the Company acquired 14 groups
of companies (the "Founding Companies") in the rail system services and related
products industry. The aggregate consideration paid by the Company to acquire
these companies was approximately $51,100,000 in cash and 8,867,648 shares of
RailWorks common stock.

     For accounting and financial statement purposes, Comstock Holdings, Inc.
(one of the Founding Companies) ("Comstock" or the "Accounting Acquirer") has
been identified as the accounting acquirer consistent with Staff Accounting
Bulletin ("SAB") No. 97 of the Securities and Exchange Commission. The
acquisitions of the remaining Founding Companies were accounted for using the
purchase method of accounting and accordingly, the purchase price has been
allocated to the assets acquired and the liabilities assumed based upon the fair
values at the date of acquisition. The acquisitions of the Founding Companies
resulted in the recording of goodwill of approximately $94,817,000, which is
being amortized over 40 years.

     On November 4, 1998, the Company acquired substantially all of the net
assets of Sheldon Electric, Inc. ("Sheldon"). Also, on November 4, 1998, the
Company acquired the stock of Armcore Railroad Contractors, Inc. ("Armcore"), an
Indiana corporation located in Frankfurt, Indiana. The aggregate price paid for
these acquisitions was approximately $3,100,000 in cash. The acquisitions of
Sheldon and Armcore were accounted for using the purchase method of accounting.
The estimated goodwill associated with these acquisitions aggregated
approximately $2,449,000.

     Comstock was incorporated on November 20, 1996 as a Delaware corporation
for the purpose of acquiring L.K. Comstock & Company, Inc. (the "Predecessor
Company"). Comstock had no operations from incorporation through January 1,
1997.

     Effective January 1, 1997, Comstock purchased the stock of the Predecessor
Company. The financial statements, including those of the Predecessor Company
prior to its acquisition, have been prepared by Comstock management and present
the financial position and results of operations of Comstock as of and for the
year ended December 31, 1997 and of the Predecessor Company for the periods
prior to January 1, 1997. Accordingly, the financial information for periods
prior to 1997 do not reflect the significant impact of the Predecessor Company
acquisition or of the purchase accounting adjustments on the financial position
and results of operations of Comstock.

     The Predecessor Company was acquired by Comstock through various agreements
(the "Agreements") entered into with Comstock Group, Inc. ("Group", the
Predecessor Company's former parent), Spie Group Inc. ("Spie", the parent of
Group), Spie Enertrans SA ("Enertrans", the former parent of Spie) and Schneider
Electric Holdings Inc. ("Schneider", parent of Spie). The Agreements principally
called for: (1) the sale of the common stock of the Predecessor Company to
Comstock (the "Sale"), (2) the issuance of various contingent promissory notes
by Comstock to Enertrans and Group in exchange for approximately $18,903,000,
(3) the transfer of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

various intangible assets of Spie to Comstock, (4) the provision for various
income tax elections and indemnifications, and (5) certain other
indemnifications and cooperative understandings. The effects of the Agreements
have been accounted for as a purchase in the accompanying financial statements
as of and for the year ended December 31, 1997. In connection with the IPO of
RailWorks, Group agreed to accept a one-time payment of $1,600,000 to satisfy
all potential contingent payments owed in connection with the Agreements. Such
payment was made by RailWorks on September 8, 1998.

     As part of the Agreements, certain intangible assets (recorded at no value)
were assigned to Comstock. In addition, Comstock issued a promissory note (the
"Contingent Promissory Note"), collateralized by certain investments related to
customer contracts involving claims and an investment in a joint venture (the
"Investments"). The remaining balance of the Contingent Promissory Note of
$12,240,000 at December 31, 1998 is payable only from amounts collected by
Comstock relating to the Investments until April 3, 2007, at which time the note
is cancelled. As such, Enertrans and any successor to it or creditor may not
look to any other Comstock assets to satisfy this indebtedness. Accordingly,
management believes a right of offset exists for financial reporting purposes
and the Investments and the Contingent Promissory Note have been offset in the
accompanying balance sheets at December 31, 1998 and 1997 in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 125 "Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of Liabilities."

     In connection with the Sale, $5,095,000 of cash from the Predecessor
Company was used by Comstock to fund its acquisition of the Predecessor Company.
Accordingly, and as a result of the purchase price adjustments, the fair value
of the net assets acquired exceeds the purchase price funded solely by Comstock.
In accordance with Accounting Principles Board Opinion No. 16 "Business
Combinations", the excess of the cost of net assets acquired first reduced the
non current assets to zero with the remainder allocated to "Excess of Acquired
Net Assets Over Cost", (negative goodwill) which amount is being amortized over
40 years.

2. NATURE OF BUSINESS

     RailWorks was formed to become a leading nationwide provider of rail system
services, including construction and rehabilitation, repair and maintenance, and
related products. The Company provides contracting services and rail related
products to a broad range of customers including Class I railroads, transit
authorities and commuter railroads, municipalities, industrial companies and
commercial enterprises. RailWorks operates principally in the United States.

     During 1998, the Company adopted SFAS No. 131 "Disclosures about Segments
of an Enterprise and Related Information" ("SFAS No. 131"). In accordance with
SFAS No. 131, the Company has three reportable segments: (1) transit services,
(2) rail construction, rehabilitation, repair and maintenance services and (3)
rail products and supplies. The transit services segment provides transit
construction and rehabilitation services, as well as installation of signaling,
communications and electrical systems. The rail construction services segment
provides design, engineering, construction, rehabilitation and repair and
maintenance of track systems. The rail products and supplies segment provides a
broad range of rail related products, including treated wood ties. The
accounting policies of the segments are the same as those described in the
summary of significant accounting policies. RailWorks evaluates performance
based on profit or loss from operations before income taxes, interest income and
expense, and non-recurring gains and losses.

3. SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the accounts of
the Company and its wholly owned subsidiaries. All significant intercompany
transactions have been eliminated.

     The Company accounts for intersegment sales and transfers as if the sales
or transfers were to third parties, utilizing current market prices and arms
length terms and conditions.

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 amount 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

     The Company recognizes revenues from fixed-fee contracts using the
percentage-of-completion method, measured by the percentage of cost incurred to
date to management's estimated total cost for each contract. This method is used
because management considers total cost to be the best available measure of
progress on the contracts. Changes in job performance, job conditions and
estimated profitability may result in revisions to cost and income, which are
recognized in the period in which the revisions are determined. Revenues from
time-and-material contracts are recognized currently as the work is performed.

     Contract costs include all direct material, labor and equipment costs and
those indirect costs related to contract performance and are charged to cost of
revenues as incurred. Provisions for estimated losses on uncompleted contracts
are made in the period in which such losses are determined.

     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts," represents billings in excess of revenues recognized.

     With regard to the rail products segment, the Company recognizes revenue
when products are delivered to customers pursuant to shipping agreements. Cost
of goods sold includes the raw materials cost, labor and overhead costs of
producing the product.

     In accordance with industry practice, the Company classifies as current all
assets and liabilities related to the performance of long-term contracts. The
contracting cycle for certain long-term contracts may extend beyond one year
and, accordingly, collection or payment of amounts related to these contracts
may extend beyond one year.

CASH AND CASH EQUIVALENTS

     The Company considers cash and cash equivalents to include cash on hand and
temporary cash investments purchased with an original maturity of three months
or less.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

INVENTORIES

     Inventories are stated at the lower of cost or market. Cost is determined
by the first-in, first-out (FIFO) method. Inventory consists of stored materials
and parts to be used in long-term construction contracts and raw materials and
finished goods produced by the rail products segment companies.

PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are recorded at cost. Included in machinery
and equipment is specialty construction tools and other equipment which,
although purchased in connection with a particular contract, is expected to be
used in future contracts. Depreciation is computed using the straight-line
method over the estimated useful lives of the assets as follows:

<TABLE>
<S>                                                           <C>
Building and improvements...................................  15 - 30 years
Machinery and equipment.....................................    3 - 7 years
Office furniture and equipment..............................    5 - 7 years
Transportation equipment....................................    5 - 7 years
</TABLE>

     Leasehold improvements are capitalized and amortized over the shorter of
the estimated useful lives of the assets or the terms of the related leases.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments, which extend the
useful lives of existing equipment, are capitalized and depreciated. Upon
retirement or disposition of property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any resulting gain or
loss is recognized in the statements of operations.

INCOME TAXES

     The Company follows the liability method of accounting for income taxes in
accordance with SFAS No. 109. Under this method, deferred income taxes are
recorded based upon differences between the financial reporting and tax bases of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the underlying assets or liabilities are received or
settled. Valuation allowances are established when necessary to reduce deferred
tax assets to the amount expected to be realized.

EARNINGS PER SHARE

     In February 1997, the Financial Accounting Standards Board issued SFAS No.
128, "Earnings per Share". This statement supersedes APB Opinion No. 15,
"Earnings per Share" and simplifies the computation of earnings per share
("EPS"). Primary EPS is replaced with a presentation of basic EPS. Basic EPS
includes no dilution and is computed by dividing income available to common
stockholders by the weighted-average number of common shares outstanding for the
period. Fully diluted EPS is replaced with diluted EPS. Diluted EPS reflects the
potential dilution if certain securities are converted and also includes certain
shares that are contingently issuable. The following is the computation of
earnings per share (in thousands, except per share data):

* Outstanding stock options and convertible preferred shares would be
  antidilutive in 1998 and therefore were excluded.

     No stock options or convertible preferred shares were outstanding in 1997.

INTANGIBLE ASSETS

     Intangible assets consist primarily of excess purchase price over net
assets acquired (goodwill), which is being amortized over its estimated useful
life of 40 years. In conformance with SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of",
the Company's management regularly evaluates whether events and circumstances
indicate that the remaining balance of intangibles or other long-lived assets
may not be recoverable.

     The Excess of Acquired Net Assets Over Cost (negative goodwill) was
generated from the acquisition of the Predecessor Company. The amortization
period of the negative goodwill is 40 years. During 1998, the negative goodwill
was reduced by the additional $1,600,000 purchase price paid to Group.

     Amortization expense, including negative amortization of $252,000 in 1998
and $269,000 in 1997, of the years ended December 31, 1998, 1997 and 1996
amounted to $965,000, $(269,000) and $16,000, respectively.

     Accounts receivable at December 31, 1998 and 1997 consisted of the
following (in thousands):

</TABLE>

     Retainages of approximately $5,783,000 and $4,388,000 at December 31, 1998
and 1997 are invested in U.S. government obligations and municipal bonds. The
Company anticipates that 47% of all retainages at December 31, 1998 will be
collected within one year.

     Costs and estimated earnings in excess of billings on uncompleted contracts
arise when revenues have been recorded but the amounts cannot be billed
currently under the terms of the contracts. Such amounts are recoverable from
customers upon various measures of performance, including achievement of certain
milestones, completion of specified units or completion of the contract. The
Company anticipates that substantially all amounts, other than unanticipated
additional contract costs (see below), will be billed and collected within one
year.

     The Company has recorded as costs and estimated earnings in excess in
billings on uncompleted contracts amounts that it seeks or will seek to collect
from customers or others for error or changes in contract specifications or
design, contract change orders in dispute or unapproved as to both scope and
price, or other customer-related causes of unanticipated additional contract
costs (pending change orders or claims). These amounts are recorded at their
estimated net realizable value when realization is probable and can be
reasonably estimated. No profit is recognized on the construction costs incurred
in connection with these amounts. Pending change orders and claims involve the
use of estimates and it is reasonably possible that revisions to the estimated
recoverable amounts of recorded pending change orders and claims may be made in
the near-term. Claims made by the Company involve negotiation and, in certain
cases litigation. The Company expenses such costs as incurred, although it may
seek to recover these costs as part of the claim. The Company believes that it
has established legal bases for pursuing recovery of recorded claims and it is
management's intention to pursue and litigate these claims, if necessary, until
a decision or settlement is reached.

     The Company is pursuing unanticipated additional contract costs on certain
completed contracts. Costs and estimated earnings in excess of billings on
uncompleted contracts includes unbilled revenues of approximately $11,054,000
and $3,915,000 at December 31, 1998 and 1997, respectively, related to these
contracts. In addition, billed accounts receivable and retainages include
contractually billed amounts related to these contracts of approximately
$3,105,000 and $2,257,000 at December 31, 1998 and 1997, respectively. Certain
contractually billed amounts related to these contracts may not be paid by the
customer to the Company until final resolution of the contract. At December 31,
1998 and 1997, the Company had reserves of approximately $4,500,00 and
$2,285,000, respectively, related to unbilled revenue and estimated legal costs
to settle.

(a)  On August 4, 1998, the Company entered into a secured $75,000,000 revolving
     credit agreement with NationsBank, N.A. (the "Credit Facility"). The Credit
     Facility expires on August 4, 2001; however, the Company may request the
     bank to extend the agreement for two, one-year periods. The proceeds of the
     Credit Facility are to be utilized for working capital, future acquisitions
     and letters of credit. The aggregate amount of letter of credit obligations
     that can be drawn against the Credit Facility shall not exceed $20,000,000.
     There were no letters of credit outstanding at December 31, 1998. Interest
     on loans, commitment fees, and letter of credit fees are based upon
     consolidated leverage ratios in a pricing matrix which may be based on
     prime or LIBOR. The annual interest rates in effect at December 31, 1998,
     for prime and LIBOR borrowings were 8.5% and 7.26%, respectively. A one
     time facility fee of 2% was paid on the total Credit Facility.

(b)  On April 4, 1997, the Company entered into a secured revolving credit
     agreement (the "Revolver") with a maximum aggregate principal amount of
     $15,000,000 (the "Commitment"). Interest on Base Rate loans was at a rate
     of 1% plus the Base Rate, as defined (approximately prime rate); interest
     on Eurodollar loans was at 3.25% plus the Eurodollar Rate, as defined
     (approximately LIBOR). An annual facility fee of 1% and a commitment fee of
     1/2 of 1% were payable on the total Commitment and the total unused
     Commitment, respectively. Up to $10,000,000 of letters of credit could be
     drawn against the Commitment, $2,911,655 of which was drawn at December 31,
     1997. This obligation was repaid in its entirety on August 4, 1998.

(c)  On December 11, 1997, the Company entered into a short-term secured
     revolving credit agreement (the "Temporary Revolver") with a maximum
     principal amount of $2,000,000. Interest on the unpaid principal was at a
     rate of 2% plus the Base Rate (approximately prime rate). The Temporary
     Revolver was extended from its original maturity and was repaid in its
     entirety on August 4, 1998.

(d)  Interest on this agreement was payable semi-annually at a rate of 8.5%.
     This obligation was repaid in its entirety on August 4, 1998.

     The Credit Facility is secured by a first lien on all of the capital stock
of the Company's subsidiaries and on all accounts receivable of the Company and
its subsidiaries. In addition, the Credit Facility contains a negative pledge on
all other assets of the Company and its subsidiaries. The Credit Facility
contains restrictive covenants that, among other things impose limitations on
the Company with respect to its ability to incur additional indebtedness, make
certain investments, sell assets or pay dividends. The Credit Facility also
contains various financial

8. PREFERRED STOCK

     The Company has authorized 10,000,000 shares of Series A convertible
preferred stock. The stock has no voting rights, shares dividends ratably with
the common stock, is non-cumulative and has a liquidation preference over shares
of common stock. Each share of preferred stock is convertible into 100 shares of
the Company's common stock.

     On October 8, 1998, the Company issued 13,700 shares of its nonvoting
Series A convertible preferred stock in exchange for 1,370,000 shares of common
stock. Each share of Series A convertible preferred stock is convertible to 100
shares of common stock upon five days prior written notice from the holder,
subject to certain conditions.

9. STOCK OPTION PLAN

     On August 13, 1998, the Company approved the 1998 Stock Incentive Plan (the
"Plan") which provides for the granting or awarding of stock options and stock
appreciation rights to non-employee directors, officers and other key employees
(including officers of the Subsidiaries) and consultants. The Plan reserves for
issuance 2,000,000 shares of common stock. In general, the terms of the option
awards (including vesting schedules) will be established by the Compensation
Committee of the Company's board of directors.

     During 1998 options covering an aggregate of 30,000 shares of common stock
were issued under the Plan. Two non-employee directors were each issued options
to purchase 10,000 shares of common stock at the IPO price. Options to purchase
10,000 shares were also issued to a President of one of the Subsidiaries at the
price of the common stock on the date of the grant. The options expire ten years
after the date of grant.

liabilities at December 31, 1998 and 1997 are reserves of $2,348,000 and
$3,574,000, respectively, relating to these insurance liabilities. The Company,
including Comstock, currently participates in a paid indemnity plan for these
insurance coverages.

     Comstock sponsored an unfunded, fully insured postretirement medical plan
covering eligible retirees and their dependents which it elected to terminate
effective December 31, 1997. In 1996 Comstock offered, at group rates,
comprehensive medical care benefits to retirees and their covered dependents.
Comstock contributed approximately one-half of the total premium medical cost.
Under the plan, employees were eligible to enroll on the first day of the month
following retirement from Comstock after age 55 and ten years of service. Upon
adoption of SFAS No. 106, "Employers' Accounting for Postretirement Benefits
other than Pensions" the accumulated postretirement benefit obligation was
$943,000. This amount was amortized over 20 years.

     The postretirement benefit cost for 1996 included the following items (in
thousands):

</TABLE>

     The assumed discount rate used to measure the accumulated postretirement
benefit obligation was 7.25% in 1996. The assumed health care cost trend rate
was 9.5% in December 31, 1996, gradually decreasing to an ultimate rate of 5% in
2004 for participants under age 65. For those above age 65, a rate of 7.5% was
used in 1996, gradually decreasing to an ultimate rate of 5% in 2004. A one
percent increase in the assumed health care cost trend rate would increase costs
by $25,000 in 1996. This plan was discontinued in 1997.

     The Company also has nonqualified defined benefit plans covering certain
current and former employees of one of the Subsidiaries which provide benefits
based on years of service and compensation. In aggregate, at December 31, 1998
and 1997 approximately $3,007,000 and $1,518,000, respectively relating to these
programs is included in the accompanying balance sheets.

     The Company's self-insurance programs and certain employee benefit plan
liabilities are estimated using actuarial estimates and management assumptions.
These estimates are based on historical information, along with certain
assumptions about future events. Changes in assumptions, as well as changes in
actual experience could cause these estimates to change.

     The Company has established two bonus incentive plans (the "Plans")
covering certain employees. The first bonus pool consists of 10% of the
Company's pre-tax profits and the second bonus pool consists of 15% of the
amount by which the Company's net income exceeds certain benchmarks. No benefits
were earned or paid under either of the Plans during 1998.

11. LEASE COMMITMENTS

     The Company and its subsidiaries lease various office buildings, machinery,
equipment, and vehicles under operating leases expiring at various dates through
2004. Most of the real property leases have escalation clauses related to
increases in real property taxes. Future minimum lease payments under operating
leases are as follows (in thousands):

     Rent expense for all operating leases, including amounts charged to cost of
revenues, for the year ended December 31, 1998, 1997 and 1996 was approximately
$3,047,000, $2,685,000 and $3,527,000, respectively.

12. RELATED-PARTY TRANSACTIONS

LEASING TRANSACTIONS

     Certain of the subsidiaries lease their operating facilities from former
Founding Company owners who remained employees or directors of the Company.
Total rent paid to related parties for 1998 was $330,000. The Company believes
the rents to be the fair market rental value of the property.

13. COMMITMENTS AND CONTINGENCIES

PERFORMANCE BONDS

     The Company's performance under certain construction contracts is secured
by performance bonds for which the Company pays a separate fee.

EMPLOYMENT CONTRACTS

     Certain executives of the Company have entered into employment agreements
with the Company. In general, the employment agreements provide that, in the
event of a termination of employment by the Company without cause, such employee
will be entitled to receive from the Company an amount in cash equal to the
employee's then current annual base salary for the remainder of the term.

CONTINGENT PURCHASE PRICE FOR ACQUISITIONS

     The sellers of Sheldon and Armcore are eligible to receive additional cash
amounts ("earnouts"), consisting of cash, as adjustments to the purchase prices
paid for those companies. Such cash payments are contingent upon the achievement
of earnings targets for 1999, 2000 and 2001.

ENVIRONMENTAL

     The Company's operations are subject to extensive federal, state and local
regulations under environmental laws and regulations concerning, among other
things, emissions to the air, discharges to waters and the generation, handling,
storage, transportation, treatment and disposal of waste, hazardous substances,
underground and aboveground storage tanks and soil and

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

groundwater contamination. The Company is also subject to certain Federal, state
and local environmental laws and regulations relating to the use of creosote.
Creosote is used in certain of the Company's manufacturing processes to treat
wood railroad ties so that they can withstand exposure to outside elements.
Creosote, a coal tar treated derivative, has been recognized by the
environmental regulating agencies as a hazardous material. The Company believes
that it is in material compliance with all of the various regulations applicable
to their businesses and has not been notified of any violations by regulatory
agencies.

LITIGATION

     The Company is involved in legal proceedings and claims, asserted by and
against the Company, which have arisen in the ordinary course of business. The
Company believes it has a number of valid defenses to these actions and the
Company intends to vigorously defend or assert these claims. Management
believes, upon advice of outside counsel, that none of these actions will have a
material adverse effect on the financial position or results of operations of
the Company.

14. LOANS TO OFFICERS

     Pursuant to their employment agreements, certain officers of the Company
have been granted loans for the payment of income taxes related to stock grants.
These loans have a term of five years, are interest bearing and are
collateralized by the stock granted.

15. FINANCIAL INSTRUMENTS

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133").
SFAS 133 establishes accounting and reporting standards requiring that every
derivative instrument be recorded in the balance sheet as either an asset or a
liability measured at its fair value. SFAS 133 requires that changes in each
derivative's fair value be recognized into earnings unless specific hedge
accounting criteria are met. The Company does not anticipate that SFAS 133 will
have a material impact upon its operations.

INTEREST RATE SWAPS

     The Company has entered into an interest rate swap agreement to manage
exposure to interest rate fluctuations. The outstanding agreement involves the
exchange of floating rate interest payments for fixed rate interest payments
over a specified time period without the exchange of any underlying principal
amounts. The Company's credit exposure is limited to the fair value of the
agreements, and the Company only enters into agreements with highly rated
counterparties. The Company does not enter into interest rate swap agreements
for trading or speculative purposes and matches the terms and contract notional
amounts to existing debt. The net amounts paid or received under interest rate
swap agreements are recognized as an adjustment to interest expense.

     At December 31, 1998, the Company had an interest rate swap agreement with
a total notional value of $10,000,000, expiring December 7, 2001 or December 7,
2000 at the counterparties' option. The agreements effectively convert floating
rate obligations to a fixed rate of 4.85 percent. If the Company were to
terminate its existing interest rate swap agreements, any resulting gain or loss
would be deferred and recognized over the remaining life of the related debt.

                     RAILWORKS CORPORATION AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     RailWorks uses the following methods and assumptions in estimating the fair
value of its financial instruments:

          Cash and Cash Equivalents -- The carrying amount is equal to fair
     market value due to their short-term nature.

          U.S. Government and Municipal Bonds -- These securities are classified
     as held to maturity and are valued at cost which approximates market value.

          Debt -- The Company's bank loans and floating rate debt approximate
     fair value. The fair value of fixed rate long-term debt is based upon
     quoted market prices for these or similar issues, or rates currently
     available to the Company for debt with similar terms and maturities.

          Interest Rate Swap Agreements -- The fair value of interest rate swap
     agreements is based upon the estimated cost to terminate the agreements,
     taking into account current interest rates and creditworthiness of the
     counterparties. The fair value at December 31, 1998 was approximately
     $10,500.

16. SEGMENT REPORTING

     Comstock and the Predecessor Company operated in one reportable segment:
transit services. Accordingly, no additional disclosures are required under SFAS
No. 131. The following matrix presents operational and financial condition data
as of and for the year ended December 31, 1998 for analysis by reportable

18. SUBSEQUENT EVENTS (UNAUDITED)

     On January 7, 1999, the Company acquired all the stock of Mid West Railroad
Construction Maintenance Corporation of Wyoming (Mid West) which specializes in
construction, repair and maintenance of railroad tracks in various western
states. On January 26, 1999, the Company acquired all the stock of Gantrex Group
(Gantrex) which manufactures and supplies crane rail fastening systems including
pad manufacturing, extrusion and continuous vulcanizing capabilities. On January
29, 1999, the Company acquired all the stock of FCM Rail, Ltd. (FCM) which
provides customized leasing services to users of on track rail equipment. On
February 1, 1999, the Company acquired all of the stock of F & V Metro
Contracting Corp. and Affiliates (F & V) which performs electrical and
mechanical installations for transit and transportation agencies in the
metropolitan New York City area. The acquisitions were accounted for using the
purchase method of accounting and accordingly, the purchase price has been
allocated to the assets acquired and the liabilities assumed based upon the fair
values at the date of acquisition. The combined purchase price was $26,000,000
in cash, $8,833,000 of promissory notes payable and 100,000 shares of Common
Stock, plus the potential to receive earnouts if targeted revenue and profit
goals are achieved over the next 5 years. The estimated fair market value of
assets purchased was approximately $6,300,000 and the estimated goodwill was
$29,500,000. Any additional purchase price paid will increase the goodwill
reported. The estimated fair market values reflected above are based on
preliminary estimates and assumptions and are subject to revision.

                                  (UNAUDITED)

1. BASIS OF PRESENTATION


     The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and

2. ORGANIZATION



     RailWorks Corporation ("RailWorks" or the "Company") was incorporated in
Delaware on March 20, 1998 and was initially capitalized on such date through
the sale of 10 shares of Common Stock for an aggregate purchase price of $100.
RailWorks seeks to become a leading nationwide provider of rail system services,
including construction and rehabilitation, repair and maintenance, and related
products. RailWorks' strategy is to provide a full range of rail related
services and products on a national basis and offer integrated rail system
solutions. To accomplish this objective, RailWorks acquired, effective August 4,
1998, (the "Acquisitions") fourteen U.S. businesses (the "Founding Companies"),
completed an initial public offering (the "Offering") of five million shares of
its Common Stock on the same date (taken together the "Consolidation") and,
subsequent to the Consolidation, acquired, through merger or purchase similar
companies to expand its operations. RailWorks and the Founding Companies merged
together upon consummation of the Offering.



     For accounting and financial statement purposes, Comstock Holdings, Inc.
(one of the Founding Companies) ("Comstock" or the "Accounting Acquirer") has
been identified as the accounting acquirer consistent with Staff Accounting
Bulletin ("SAB") No. 97 of the Securities and Exchange Commission. The
historical financial statements of RailWorks prior to August 4, 1998, are those
of Comstock. The acquisitions of the remaining Founding Companies and subsequent
acquired companies have been accounted for as purchases in accordance with
Accounting Principles Board ("APB") Statement No. 16 "Business Combinations".
Each purchase price has been allocated to the assets and the liabilities assumed
based upon the estimated fair values at the date of acquisition.



     On November 4, 1998, the Company acquired substantially all of the net
assets of Sheldon Electric, Inc. ("Sheldon"). Also, on November 4, 1998, the
Company acquired all of the outstanding stock of Armcore Railroad Contractors,
Inc. ("Armcore"), an Indiana corporation, located in Frankfort, Indiana. During
1999, the Company recorded an additional $4,300,000 in goodwill related to the
settlement of contingent purchase price payments and the resolution of the
uncertainties related to the fair value of contracts acquired.



     On January 7, 1999, the Company acquired all of the outstanding stock of
MidWest Railroad Construction & Maintenance Corporation of Wyoming ("Midwest")
which specializes in construction, repair and maintenance or railroad tracks in
various western states. On January 26, 1999, the Company acquired all of the
outstanding stock of Gantrex Group ("Gantrex") which manufactures and supplies
crane rail fastening systems including pad manufacturing, extrusion and
continuous vulcanizing capabilities. On January 29, 1999, the Company acquired
all of the outstanding stock of FCM Rail, Ltd. ("FCM") which provides customized
leasing services to users

of on track rail equipment. In March 1999, the Company acquired all of the
outstanding stock of F&V Metro Contracting Corp. and Affiliates ("F&V") which
performs electrical and mechanical installations for transit and transportation
agencies in the metropolitan New York City area. The combined purchase price for
these first quarter 1999 acquisitions was $36,000,000 in cash, $9,000,000 of
promissory notes payable and deferred payments, and 100,000 shares of RailWorks
Common Stock at an aggregate value of $1,000,000, plus the potential to receive
earnouts if targeted revenue and profit goals are achieved over the next five
years. The fair market value of assets purchased was $12,055,000 and the
preliminary goodwill was approximately $33,945,000. Subsequent to the initial
recording of goodwill, an additional $6,552,000 of goodwill has been recorded
through September 30, 1999 relating to these first quarter 1999 acquisitions.
Such adjustments reflect the settlement of contingent purchase price payments
and the resolution of the uncertainties related to the fair value of contracts
acquired.



     On April 12, 1999, the Company acquired all of the outstanding stock of
McCord Treated Wood, Inc. and Birmingham Wood, Inc. ("McCord") which supply
creosote treated wooden cross ties throughout the Southeastern United States. On
April 30, 1999, the Company acquired all of the outstanding stock of M-Track
Enterprises, Inc. ("M-Track") which specializes in rail transit construction,
repair and maintenance of track in the metropolitan New York City area. In May
1999, the Company acquired all of the outstanding stock of Pacific Northern Rail
Contractors, Inc. ("PNR") which specializes in construction, repair and
maintenance of railroad tracks throughout Canada. On June 3, 1999, the company
acquired all the outstanding stock of Neosho, Incorporated ("Neosho") which
provides track and transit construction, repair and maintenance to public and
private industrial customers nationally. On June 30, 1999, the Company acquired
all of the outstanding stock of Earl Campbell Construction Company, Inc.
("Campbell") which specializes in construction, repair and maintenance of
railroad tracks in various Southern states. The combined purchase price for
these second quarter 1999 acquisitions was $49,535,000 in cash, $4,000,000 of
promissory notes payable and deferred payments and 93,842 shares of common stock
at an aggregate value of $1,000,000 plus the potential to receive earn-outs if
targeted revenue and profit goals are achieved over the next five years. The
fair market value of assets purchased for the second quarter 1999 acquisitions
was approximately $16,262,000 and the preliminary goodwill recorded was
approximately $38,273,000. Subsequent to the initial recording of goodwill, an
additional $2,208,000 of goodwill has been recorded through September 30, 1999
relating to these third quarter 1999 acquisitions. Such adjustments represent
the resolution of litigation which was pending at the time of acquisition.



     On August 4, 1999, the Company acquired all of the outstanding stock of
Wood Waste Energy, Inc. ("Wood Waste") which collects used cross ties along the
railroad rights of way and processes them into fuel which is sold to industrial
customers. The purchases price for this acquisition was $5,000,000 in cash and a
$3,000,000 promissory note, plus the potential to receive earn-outs if targeted
revenue and profit goals are achieved for the years ended December 31, 2000 and
2001. The fair market value of assets purchased was approximately $1,078,000 and
the preliminary goodwill recorded was approximately $6,922,000.



     Assets acquired and liabilities assumed are recorded at their fair values
at the time of acquisition. The excess of the purchase price over the net fair
value is allocated to goodwill. The estimated fair values of acquired assets and
liabilities are subject to adjustment pending finalization of, among other
things, certain fixed asset appraisals and the quantification of contract and/or
litigation uncertainties based on information which was not available at the
time of acquisition but subsequently obtained. Goodwill is adjusted as these
items are resolved as well as when, and if, additional contingent purchase price
is paid. The Company evaluates periodically whether events and circumstances
indicate that any goodwill is impaired.

3. SENIOR SUBORDINATED NOTES



     On September 30, 1999, the Company sold $50 million of its 11.5% senior
subordinated notes (the "Notes"). The Notes were sold in a private placement
pursuant to Rule 144A under the Securities Act of 1933. The Company has filed a
registration statement on Form S-4, pursuant to which it will offer to exchange
registered notes that are substantially identical to the Notes for the Notes.

interest rate of 11.5%, payable semi-annually and are due in 2009 with no
interim amortization requirements.

                             RAILWORKS CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


     On August 13, 1998, the Company approved the 1998 Stock Incentive Plan (the
"Plan"), which provides for the granting or awarding of stock options and stock
appreciation rights to non-employee directors, officers and other key employees
(including officers of the Subsidiaries) and consultants. The Plan reserves for
issuance 2,000,000 shares of common stock. In general, the terms of the option
awards (including vesting schedules) will be established by the Compensation
Committee of the Company's board of directors.



     During the three months ended September 30, 1999 the Company issued options
to purchase 172,500 shares of common stock to seven employees of RailWorks. The
exercise price of the options was the market price of the stock on the date of
grant.



     The options expire ten years after the date of grant. Also during the
quarter, the Company issued options to purchase 10,000 shares of common stock to
a newly appointed outside director of RailWorks. The exercise price of the
options was the market price of the stock on the date of grant. The options
expire ten years after the date of grant.



7. FINANCIAL INFORMATION FOR SUBSIDIARY GUARANTOR AND NON-GUARANTOR SUBSIDIARIES



     The Company conducts a significant portion of its business through its
subsidiaries. All of the Company's domestic subsidiaries have fully and
unconditionally guaranteed the Notes ("Subsidiary Guarantors"). The Company's
non-U.S. subsidiaries have not guaranteed the Notes (the "Non-Guarantor
Subsidiaries"). The Notes are effectively subordinated in right of payment to
all indebtedness and other liabilities (including trade payables) of the
Non-Guarantor Subsidiaries.



     Set forth below are condensed consolidating financial statements for the
Company, the Subsidiary Guarantors and the Non-Guarantor Subsidiaries as of
September 30, 1999 and for the three and nine months ended September 30, 1999.
The Company has not presented statements of operations for the three or nine
months ended September 30, 1998 or a statement of cash flows for the nine months
ended September 30, 1998 because during such periods all of the Company's
subsidiaries had fully and unconditionally guaranteed the Notes. The equity
method has been used by the Company with respect to investments in subsidiaries.
Separate financial statements for the Subsidiary Guarantors are not presented
based on management's determination that they do not provide additional
information that is material to investors.

8. SUBSEQUENT EVENTS



ACQUISITION



     On October 22, 1999, the Company acquired all of the outstanding stock of
W. T. Byler Corporation ("Byler") which provides railroad construction and
maintenance, grading, excavation, soil stabilization, concrete paving, asphalt
paving and underground utilities construction to public and private industrial
customers located throughout Texas and the other Gulf coast states.



TERM LOAN



     On October 29, 1999, the Company secured a $30 million term loan (the "Term
Loan"). The Term Loan was established in conjunction with the Company's current
revolving credit facility (the "Credit Facility") utilizing identical
collateral. The Term Loan is due and payable in twenty (20) consecutive
quarterly installments ranging from $75,000 to $7.2 million through October 29,
2004. The proceeds of the Term Loan were utilized to pay down the existing
Credit Facility. The interest rate is variable based upon the bank's Base Rate
plus 2% per annum.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
                               DECEMBER 31, 1998

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF COMBINATION

     The parent companies and their subsidiaries employ accounting policies and
standards of financial disclosure which are in accordance with the
recommendations of the Canadian Institute of Chartered Accountants.

     All significant intercompany accounts and transactions have been
eliminated.

     The combined financial statements include the accounts of:

          1. GANTREX GROUP LIMITED consolidated with its wholly owned
     subsidiaries:

             Cranequip Limited
             Gantrex Limited
             Gantrex Systems Limited

          2. NORAPCO LIMITED

          3. GANTREX HOLDING CORPORATION consolidated with its wholly owned
             subsidiary, Gantrex Corporation

          4. GANTREX SYSTEMS INC.

USE OF ESTIMATES

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

INVENTORIES

     Inventories are valued at the lower of cost and net realizable value with
cost being determined on a first-in, first-out basis.

CAPITAL ASSETS

     The Companies record their capital assets at cost. Depreciation and
amortization are provided in order to allocate the costs over the estimated
useful lives of the capital assets as follows:

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

TRANSLATION OF FOREIGN CURRENCIES

     All foreign companies and their subsidiaries included in the combined group
are treated as integrated foreign operations for combination purposes.
Accordingly, their monetary assets and liabilities have been converted to United
States dollars using the exchange rate in effect at the balance sheet date. All
other assets and liabilities are converted at historical rates. Revenues and
expenses are translated at average exchange rates prevailing during the year.
The resulting exchange gain/loss on translation is included in net income.

INCOME TAXES

     The Companies follow the deferral method of tax allocation in accounting
for income taxes. Under this method timing differences between accounting and
taxable income result in the recording of deferred income taxes.

7. UNCERTAINTY DUE TO THE YEAR 2000 ISSUE

     Most entities depend on computerized systems and therefore are exposed to
the Year 2000 conversion risk, which, if not properly addressed, could affect an
entity's ability to conduct normal business operations. Management is addressing
this issue, however, given the nature of this risk, it is not possible to be
certain that all aspects of the Year 2000 Issue affecting the Company and those
with whom it deals such as customers, suppliers or other third parties, will be
fully resolved without having an adverse impact on the Company's operations.

8. SUBSEQUENT EVENT

     On January 26, 1999, the shareholders of the Companies sold all of the
outstanding shares to RailWorks Corporation.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Mid West Railroad Construction and Maintenance Corporation of Wyoming:

     We have audited the accompanying balance sheet of MID WEST RAILROAD
CONSTRUCTION AND MAINTENANCE CORPORATION OF WYOMING (a Wyoming corporation) as
of December 31, 1998, and the related statements of operations, retained
earnings and cash flows for the year then ended. 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 audit.

     We conducted our audit 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 are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of MID WEST RAILROAD
CONSTRUCTION AND MAINTENANCE CORPORATION OF WYOMING as of December 31, 1998, and
the results of its operations and its cash flows for the year then ended, in
conformity with generally accepted accounting principles.

     MID WEST RAILROAD CONSTRUCTION AND MAINTENANCE CORPORATION OF WYOMING

                         NOTES TO FINANCIAL STATEMENTS

1. NATURE OF BUSINESS

     Mid West Railroad Construction and Maintenance of Wyoming ("the Company")
is a Wyoming corporation which was formed in 1988. The Company operates in
Wyoming, Utah and Colorado and other western U.S. states.

     The Company performs contracts for repair, maintenance and construction of
privately owned railroad tracks, contracts to move railroad cars on private
railroad tracks to and from common carrier interchange points and provides
railroad track engineering.

2. SIGNIFICANT ACCOUNTING POLICIES

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 vary from the estimates that were assumed
in preparing the financial statements.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of cash, accounts receivable and accounts payable
approximate fair value because of their short-term nature. The carrying amount
of long-term debt approximates fair value based on the borrowing rates currently
available to the Company for bank loans with similar terms and maturities.

REVENUE AND COST RECOGNITION

     The Company recognizes revenues from fixed-fee construction contracts using
the percentage-of-completion method, measured by the ratio of cost incurred to
date to management's estimated total cost for each contract. That method is used
because management considers total cost to be the best available measure of
progress on the contracts. Changes in job performance, job conditions and
estimated profitability may result in revisions to cost and income, which are
recognized in the period in which the revisions are determined.

     Revenues from time-and-material contracts are recognized as the work is
performed.

     Contract costs include all direct material and labor costs and those
indirect costs related to contract performance. General and administrative costs
are charged to expense as incurred. Provisions for estimated losses on
uncompleted contracts are made in the period in which such losses are
determined.

     The asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts," represents billings in excess of revenues recognized.

INVENTORY

     Inventory, principally materials and supplies, is stated at the lower of
cost or net realizable value. Cost is determined by the first-in, first-out
method.

                                      F-51
<PAGE>   177
     MID WEST RAILROAD CONSTRUCTION AND MAINTENANCE CORPORATION OF WYOMING

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment is stated at cost. Depreciation is provided
principally by use of the straight-line method over the estimated useful life of
the related asset. Accelerated methods are used for income tax reporting
purposes.

INCOME TAXES

     Deferred income taxes are determined based on the difference between the
financial statement and income tax basis of assets and liabilities using tax
rates expected to be in effect in the years in which the differences are
expected to reverse. The temporary differences related primarily to the
reporting of revenue recognition on long-term contracts, depreciation and net
operating loss carryforwards.

CASH

     From time to time, the Company's cash balance with financial institutions
exceeds the maximum FDIC insured balance of $100,000. The Company has not
experienced any losses in such accounts and believes it is not exposed to any
significant credit risk on cash.

     For the reporting of cash flows, the Company considers savings accounts and
certificate of deposits with original maturities of three months or less to be
cash.

3. ACCOUNTS RECEIVABLE

     Accounts receivable at December 31, 1998, consisted of the following:

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1. NATURE OF BUSINESS

     F & V Metro Contracting Corp. and Affiliates (the "Companies") serve as
contractors for governmental, institutional and commercial projects, primarily
in the New York City Metropolitan area. Construction work is generally performed
under fixed-price and unit-price contracts. These contracts are undertaken by
the Companies or in partnership with other contractors through joint ventures.
The length of the Companies' contracts varies but typically ranges from one to
three years.

2. SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF COMBINATION

     The combined financial statements include the accounts of F & V Metro
Contracting Corp., V & R Electrical Contractors, Inc., F & V Mechanical/V & R
Electrical -- A Joint Venture, Impulse Enterprises of N.Y., Inc. and Impulse
Enterprises of N.Y., Inc. and F & V Mechanical Plumbing & Heating Corp. A Joint
Venture, which are related by virtue of common ownership. All intercompany
balances and transactions have been eliminated in the combined financial
statements.

     The balance sheet dates for the entities included in the combined report
are as follows:

<TABLE>

</TABLE>

REVENUE AND COST RECOGNITION

     Revenues from fixed-price and unit-price, long-term construction contracts
are recognized under the percentage of completion method. Under this method,
progress towards completion is recognized according to the ratio of incurred
costs to estimated total costs.

     Contract costs include all direct material and labor costs and all other
direct and indirect costs related to contract performance. General and
administrative costs are charged to expense as incurred. Provisions for
estimated losses on uncompleted contracts are made in the period in which such
losses are determined. Changes in job performance, job conditions and estimated
profitability, including those arising from settlements, may result in revisions
to costs and income and are recognized in the period in which the revisions are
determined. Because of the inherent uncertainty in estimating the costs to
complete on contracts in process, it is at least reasonably possible that the
estimates used will change in the near term. Profit incentives are included in
revenues when their realization is reasonably assured. An amount equal to
contract costs attributable to claims is included in revenues when realization
is probable and the amount can be reliably estimated.

     The Asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The Liability, "Billings in excess of costs and estimated earnings on
uncompleted contracts," represents billings in excess of revenues recognized.

     In accordance with normal construction industry practice, the Companies
classify as current all assets and liabilities related to the performance of
long-term construction contracts. The

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

contracting cycle may extend beyond one year and, accordingly, collection or
payment of amounts related to these contracts may extend beyond one year.

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.

CASH EQUIVALENTS

     The Companies consider securities with original maturities of three months
or less to be cash equivalents.

MARKETABLE SECURITIES

     The Companies determine cost of marketable securities using the average
cost method for purposes of calculating realized gains or losses.

INVENTORY

     Inventory is valued at the lower of cost or market, with cost determined
using the first-in, first-out method and with market defined as the lower of
replacement cost or realizable value.

CONCENTRATION OF CREDIT RISK

     Substantially all of the Companies' business activity is with customers
located within the New York City metropolitan area. Substantially all of the
Companies' cash is maintained in two financial institutions, each of which are
in excess of the Federal Deposit Insurance Corporation (FDIC) insured limits of
$100,000. The Companies believe they are not exposed to any significant credit
risk on cash and cash equivalents.

PROPERTY AND EQUIPMENT

     Property and equipment is stated at cost. The costs of additions and
betterments are capitalized and expenditures for repairs and maintenance are
expensed in the period incurred. When items of property and equipment are sold
or retired, the related costs and accumulated depreciation are removed from the
accounts and any gain or loss is included in income.

     Depreciation and amortization of property and equipment is provided
utilizing accelerated methods over the estimated useful lives of the respective

surety for any payments made on their behalf and on behalf of their joint
ventures. The Companies believe that all contingent liabilities will be
satisfied by their performance on the specific contracts covered by the
agreement.

     F & V Metro Contracting Corp., in an unrelated business transaction, has
entered into an agreement with another general contractor as a guarantor on one
of its projects. F&V Metro Contracting Corp. had no equity interest in the
project and was entitled to a fee based on the profit of the project. Each party
is jointly and severally liable to the surety under a general indemnity
agreement. Included in other expenses is $1,490,646, which represents amounts
reimbursed to the surety and vendors and the anticipated remaining cost to
complete the contract. F & V Metro Contracting Corp. will seek recovery of all
amounts from the general contractor; however, no amounts have been recorded as
ultimate collection is uncertain. It is reasonably possible that F & V Metro
Contracting Corp. will have to reimburse the surety for additional amounts under
the indemnity. Any such additional reimbursement cannot be estimated at November
30, 1998.

     The Companies are involved in various legal proceedings which have been
filed against them. In the opinion of management and legal counsel, the outcome
of this litigation will not materially affect the Companies' financial position.

                       NOTES TO THE FINANCIAL STATEMENTS

1. ORGANIZATION AND NATURE OF BUSINESS

     W.T. Byler Co., Inc., (the "Company"), operates as a general contractor
performing work in the construction and repair of railroad tracks, grading,
bridge construction, paving, structural concrete work and light rail
construction projects throughout the continental United States. For the year
ended December 31, 1998, two customers accounted for 36.5% of the Company's
revenue.

2. SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

     Management used estimates and assumptions in preparing these financial
statements in accordance with generally accepted accounting principles. These
estimates and assumptions affect the reported amounts of assets and liabilities,
the disclosure of contingent assets and liabilities and the reported revenues
and expenses. Actual results could vary from the estimates that were assumed in
preparing the financial statements.

REVENUE AND COST RECOGNITION

     The Company recognizes revenues from fixed-fee contracts using the
percentage-of-completion method, measured by the percentage of cost incurred to
date to management's estimate of total cost for each contract. This method is
used because management considers total cost to be the best available measure of
progress on the contracts. Because of uncertainties in estimating costs, it is
at least reasonably possible that the estimates used could change within the
near term.

     Contract costs include all direct labor and benefits, materials,
subcontract costs, other direct costs and allocations of indirect costs of
construction. Indirect costs of construction are allocated based on direct labor
dollars or equipment usage.

     As long-term contracts extend over one or more years, revisions in
estimates of costs and earnings during the course of the work are reflected in
the accounting period in which the facts which require the revisions become
known. At the time a significant loss on a contract becomes known, the entire
amount of the estimated ultimate loss is recognized in the financial statements.

     The asset "Costs and estimated earnings in excess of billings on
uncompleted contracts" represents revenues recognized in excess of amounts
billed. The liability "Billings in excess of costs and estimated earnings on
uncompleted contracts" represents billings in excess of revenues recognized.

OPERATING CYCLE

     In accordance with industry practice, the Company classifies as current all
assets and liabilities related to the performance of long-term contracts. The
contracting cycle for certain long-term contracts may extend beyond one year
and, accordingly, collection or payment of amounts related to these contracts
may extend beyond one year.

INVENTORY

     Inventory is stated at the lower of cost or market. Inventory consists of
rail used for construction projects.

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)

PROPERTY AND EQUIPMENT

     Property and equipment is stated at cost and is depreciated using the
straight-line method over the estimated useful life of the related asset.
Significant renewals and betterments are capitalized and depreciated over the
asset's remaining useful life. The cost of routine maintenance and minor repairs
are charged to earnings as incurred. As assets are retired or otherwise disposed
of, the cost and accumulated depreciation are eliminated from the accounts and
any gain or loss is reflected in income.


     The ranges of estimated useful lives used in computing depreciation for
financial statement purposes are as follows:

</TABLE>


INCOME TAXES


     The Company has elected for tax purposes to be taxed under provisions of
Subchapter S of the Internal Revenue Code. The election allows the stockholder
to include the Company's net earnings in his own income for tax purposes.
Accordingly, the Company generally is not liable for federal income taxes. The
Company may be liable for federal income taxes related to accumulated earnings
and profits, built-in capital gains and recapture of investment tax credits.
Where allowed by state taxing authorities, the Company is also taxed as an "S"
Corporation and is not subject to tax. Any income taxes for states which do not
recognize "S" Corporation status would be included in the income tax provision.
There is no provision for income taxes required at December 31, 1998.


3. ACCOUNTS RECEIVABLE

     Accounts receivable consists of the following:

7. FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following estimated fair values of financial instruments is made in
accordance with the requirements of SFAS No. 107, "Disclosures about Fair Value
of Financial Instruments." The estimated fair value amounts have been determined
by the Company using available market information and appropriate valuation
methodologies.

CASH, ACCOUNTS RECEIVABLE AND ACCOUNTS PAYABLE

     The carrying amount of these items are a reasonable estimate of their fair
value due to their short-term nature.

LONG-TERM DEBT

     The carrying amount of the line of credit facility approximates fair value
as the interest rates are comparable to market value. The carrying value of
other loans relating to equipment approximates fair value as the interest rates
are comparable to market rates.

8. PROFIT SHARING PLAN

     The Company has a 401(k) plan that covers all eligible employees. The plan
is a salary deferral plan covering all full-time employees who are at least 21
years of age with one year of service. Employees may contribute from 1% up to
15% of their pretax annual compensation, as defined in the plan. Company
contributions to the profit sharing plan are at the discretion of the Board of
Directors. During 1998, total contributions to the plan charged to operations
were $30,770.

9. DEFERRED COMPENSATION PLAN

     The Company has a deferred compensation arrangement with a key management
employee (the "Deferred Compensation Agreement") which was executed on May 3,
1994. The Deferred Compensation Agreement provides for up to $2.6 million of
additional compensation, which vested on a straight line basis over a 10 1/2
year period of employment. Premature vesting occurs upon the sale of greater
than fifty-one percent of the Company's assets or more than a forty-nine percent
change in ownership. As a result of the Company's acquisition (see below),
premature vesting occurred in 1999.

10. SUBSEQUENT EVENT

Company to Railworks Corporation for cash and other consideration.

                                    PART II

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 102(b)(7) of the Delaware General Corporation Law (the "DGCL")
permits a corporation, in its certificate of incorporation, to limit or
eliminate, subject to some statutory limitations, the liability of directors to
the corporation or its stockholders for monetary damages for breaches of
fiduciary duty, except for liability (a) for any breach of the director's duty
of loyalty to the corporation or its stockholders, (b) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (c) under Section 174 of the DGCL, or (d) for any transaction from which
the director derived an improper personal benefit. Article 10 of the
registrant's restated Certificate of Incorporation provides that the personal
liability of directors of the registrant is eliminated to the fullest extent
permitted by Section 102(b)(7) of the DGCL.

     Under Section 145 of the DGCL, a corporation has the power to indemnify
directors and officers under certain prescribed circumstances and subject to
certain limitations against certain costs and expenses, including attorneys'
fees actually and reasonably incurred in connection with any action, suit or
proceeding, whether civil, criminal, administrative or investigative, to which
any of them is a party by reason of being a director or officer of the
corporation if it is determined that the director or officer acted in accordance
with the applicable standard of conduct set forth in such statutory provision.
Article 7 of the registrant's Bylaws provides that the registrant will indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding by reason of the
fact that he is or was a director, officer, employee or agent of the registrant,
or is or was serving at the request of the registrant as a director, officer,
employee or agent of another entity, against certain liabilities, costs and
expenses. Article 7 further permits the registrant to maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
registrant, or is or was serving at the request of the registrant as a director,
officer, employee or agent of another entity, against any liability asserted
against such person and incurred by such person in any such capacity or arising
out of his status as such, whether or not the registrant would have the power to
indemnify such person against such liability under the DGCL. The registrant
expects to maintain directors' and officers' liability insurance.

     The foregoing statements are subject to the detailed provisions of Article
10 of the registrant's restated Certificate of Incorporation.

     Pursuant to the Registration Rights Agreement, RailWorks has agreed to
indemnify holders of registrable notes against certain liabilities. Also
pursuant to the Registration Rights Agreement, RailWorks and certain
broker-dealers, including certain persons associated with such broker-dealers,
have agreed to indemnify each other against certain liabilities.

ITEM 22.  UNDERTAKINGS

     That, for purposes of determining any liability under the Securities Act of
1933, each filing of any Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1993 may be permitted to directors, officers and controlling persons of the
registrants pursuant to the foregoing provisions, or otherwise, the registrants
have been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrants of expenses incurred
or paid by a director, officer or controlling person of the registrants 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, the registrants will, unless in the opinion of their counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by them is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

     The undersigned registrants hereby undertake 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 and
included in the registration statement when it became effective.

Requirements") shall be deemed to refer also to any amendments thereto and all
subsequent Regulatory Requirements adopted as a replacement thereto having
substantially the same effect therewith; provided that Rule 144 shall not be
deemed to amend or replace Rule 144A.

               2. Exchange Offer

                  (a) The Issuers shall file with the SEC, no later than the
Filing Date, a Registration Statement (the "Exchange Offer Registration
Statement") on an appropriate registration form with respect to a registered
offer (the "Exchange Offer") to exchange any and all of the Registrable Notes
for a like aggregate principal amount of debt securities of the Company,
guaranteed by the Guarantor, that are identical in all material respects to the
Securities, except that (i) the Exchange Notes shall have been registered
pursuant to an effective registration statement under the Securities Act, shall
not contain provisions for Additional Interest, and shall contain no restrictive
legend thereon (the "Exchange Notes"), and (ii) interest thereon shall accrue
from the last date on which interest was paid on the Notes or, if no such
interest has been paid, from April 7, 1999, and which are entitled to the
benefits of the Indenture or a trust indenture which is identical in all
material respects to the Indenture (other than such changes to the Indenture or
any such identical trust indenture as are necessary to comply with the TIA) and
which, in either case, has been qualified under the TIA. The Exchange Offer
shall comply with all applicable tender offer rules and regulations under the
Exchange Act and other applicable law. The Issuers shall use their reasonable
best efforts to (x) cause the Exchange Offer Registration Statement to be
declared effective under the Securities Act on or before the Effectiveness Date;
(y) keep the Exchange Offer open for at least 30 days (or longer if required by
applicable law) after the date that notice of the Exchange Offer is mailed to
Holders; and (z) complete the Exchange Offer on or prior to the 35th day
following the date on which the Exchange Offer Registration Statement is
declared effective by the SEC. If, after the Exchange Offer Registration
Statement is initially declared effective by the SEC, the Exchange Offer or the
issuance of the Exchange Notes thereunder is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, the Exchange Offer Registration Statement shall be deemed not
to have become effective for purposes of this Agreement, unless such
interference is cured within five Business Days.

                  Each Holder (including, without limitation, each Participating
Broker-Dealer) who participates in the Exchange Offer will be required to
represent to the Company in writing



<PAGE>   7


                                      -6-



(which may be contained in the applicable letter of transmittal) that: (i) any
Exchange Notes acquired in exchange for Registrable Notes tendered is being
acquired in the ordinary course of business of the Person receiving such
Exchange Notes, whether or not such recipient is such Holder itself; (ii)
neither such Holder nor, any other Person receiving Exchange Notes from such
Holder is engaging in or intends to engage in a distribution of the Exchange
Notes; (iii) at the time of the consummation of the Exchange Offer neither such
Holder nor, any other Person receiving Exchange Notes from such Holder has an
arrangement or understanding with any Person to participate in the distribution
of the Exchange Notes in violation of the provisions of the Securities Act; (iv)
neither the Holder nor, any other Person receiving Exchange Notes from such
Holder is an "affiliate" (as defined in Rule 405) of the Company or, if it is an
affiliate of the Company, it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable; and (v) if
such Holder is a Participating Broker-Dealer, such Holder has acquired the
Registrable Notes as a result of market-making activities or other trading
activities and that it will comply with the applicable provisions of the
Securities Act. Each Holder using the Exchange Offer to participate in a
distribution of the Exchange Notes hereby acknowledges and agrees that, if the
resales are of Exchange Notes obtained by such Holder in exchange for
Registrable Notes acquired directly from the Company or an Affiliate thereof, it
(1) could not, under Commission policy as in effect on the date of this
Agreement, rely on the position of the Commission enunciated in Morgan Stanley
and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation
(available May 13, 1988), as interpreted in the Commission's letter to Shearman
& Sterling dated July 2, 1993, and similar no-action letters, and (2) must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction and that such
secondary resale transaction must be covered by an effective registration
statement containing the selling security holder information required by Item
507 or 508, as applicable, of Regulation S-K.

                  Upon consummation of the Exchange Offer in accordance with
this Section 2, the provisions of this Agreement shall continue to apply,
mutatis mutandis, solely with respect to Registrable Notes that are Private
Exchange Notes, Exchange Notes as to which Section 2(c)(iv) is applicable and
Exchange Notes held by Participating Broker-Dealers (as defined), and the
Issuers shall have no further obligation to register Registrable Notes (other
than Private Exchange Notes and Exchange Notes as to which clause 2(c)(iv)
hereof applies) pursuant to Section 3 hereof.

                  No securities other than the Securities shall be included in
the Exchange Offer Registration Statement.

                  (b) The Issuers shall include within the Prospectus contained
in the Exchange Offer Registration Statement a section entitled "Plan of
Distribution," reasonably acceptable to the Initial Purchaser, which shall
contain a summary statement of the positions




<PAGE>   8


                                      -7-



taken or policies made by the staff of the SEC with respect to the potential
"underwriter" status of any broker-dealer that is the "beneficial owner" (as
defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by such
broker-dealer in the Exchange Offer (a "Participating Broker-Dealer"), whether
such positions or policies have been publicly disseminated by the staff of the
SEC or such positions or policies represent the prevailing views of the staff of
the SEC. Such "Plan of Distribution" section shall also expressly permit, to the
extent permitted by applicable policies and regulations of the SEC, the use of
the Prospectus by all Persons subject to the prospectus delivery requirements of
the Securities Act, including, to the extent permitted by applicable policies
and regulations of the SEC, all Participating Broker-Dealers, and include a
statement describing the means by which Participating Broker-Dealers may resell
the Exchange Notes in compliance with the Securities Act.

                  The Issuers shall use their reasonable best efforts to keep
the Exchange Offer Registration Statement effective and to amend and supplement
the Prospectus contained therein in order to permit such Prospectus to be
lawfully delivered by all Persons subject to the prospectus delivery
requirements of the Securities Act for such period of time as is necessary to
comply with applicable law in connection with any resale of the Exchange Notes;
provided, however, that such period shall not be required to exceed 180 days or
such longer period if extended pursuant to the last paragraph of Section 5
hereof (the "Applicable Period").

                  If, following the date hereof, there has been announced a
change in SEC policy with respect to exchange offers such as the Exchange Offer,
that in the reasonable opinion of counsel to the Company, raises a substantial
question as to whether the Exchange Offer is permitted by applicable federal
law, the Company hereby agrees to seek a no-action letter or other favorable
decision from the SEC allowing the Company to consummate the Exchange Offer. The
Company hereby agrees to pursue the issuance of such a decision to the SEC staff
level. In connection with the foregoing, the Company hereby agrees to take all
such other actions as may be reasonably requested by the SEC or otherwise
reasonably required in connection with the issuance of such decision, including,
without limitation, (A) participating in telephonic conferences with the SEC,
(B) delivering to the SEC staff an analysis prepared by counsel to the Company
setting forth the legal bases, if any, upon which such counsel has concluded
that such an Exchange Offer should be permitted and (C) diligently pursuing a
resolution (which need not be favorable) by the SEC staff.

                  If, prior to consummation of the Exchange Offer, the Initial
Purchaser holds any Notes acquired by it that have the status of an unsold
allotment in the initial distribution, the Issuers upon the request of the
Initial Purchaser shall simultaneously with the delivery of the Exchange Notes
issue and deliver to the Initial Purchaser, in exchange (the "Private Exchange")
for such Notes held by any such Holder, a like principal amount of notes (the
"Private Exchange Notes") of the Issuers, guaranteed by the Guarantors, that are
identical in all material respects to the Exchange Notes except for the
placement of a restrictive legend on



<PAGE>   9



                                      -8-



such Private Exchange Notes. The Private Exchange Notes shall be issued pursuant
to the same indenture as the Exchange Notes and bear the same CUSIP number as
the Exchange Notes.

                  In connection with the Exchange Offer, the Issuers shall:

                  (1) mail, or cause to be mailed, to each Holder of record
          entitled to participate in the Exchange Offer a copy of the Prospectus
          forming part of the Exchange Offer Registration Statement, together
          with an appropriate letter of transmittal and related documents;

                  (2) use their reasonable best efforts to keep the Exchange
          Offer open for not less than 20 Business Days after the date that
          notice of the Exchange Offer is mailed to Holders (or longer if
          required by applicable law);

                  (3) utilize the services of a depositary for the Exchange
          Offer with an address in the Borough of Manhattan, The City of New
          York;

                  (4) permit Holders to withdraw tendered Securities at any time
          prior to the close of business, New York time, on the last Business
          Day on which the Exchange Offer remains open; and

                  (5) otherwise comply in all material respects with all
          applicable laws, rules and regulations.

                  As soon as practicable after the close of the Exchange Offer
and the Private Exchange, if any, the Issuers shall:

                  (1) accept for exchange all Registrable Notes validly tendered
          and not validly withdrawn pursuant to the Exchange Offer and the
          Private Exchange, if any;

                  (2) deliver to the Trustee for cancellation all Registrable
          Notes so accepted for exchange; and

                  (3) cause the Trustee to authenticate and deliver promptly to
          each Holder of Securities, Exchange Notes or Private Exchange Notes,
          as the case may be, equal in principal amount to the Securities of
          such Holder so accepted for exchange; provided that, in the case of
          any Securities held in global form by a depositary, authentication and
          delivery to such depositary of one or more replacement Securities in
          global form in an equivalent principal amount thereto for the account
          of such Holders in accordance with the Indenture shall satisfy such
          authentication and delivery requirement.

                  The Exchange Offer and the Private Exchange shall not be
subject to any conditions, other than that (i) the Exchange Offer or Private
Exchange, as the case may be, does not violate applicable law or any applicable
interpretation of the staff of the SEC; (ii) no action or proceeding shall have
been instituted or threatened in any court or by any governmental agency which
might materially impair the ability of the Issuers to proceed with the Exchange
Offer or the Private Exchange, and no material adverse development shall have
occurred in any existing action or proceeding with respect to the Issuers; (iii)
all governmental approvals shall have been obtained, which approvals the Issuers
deem necessary for the consummation of the Exchange Offer or Private Exchange;
and (iv) the conditions precedent to the Issuers' obligations under this
Agreement shall have been fulfilled.

                  The Exchange Notes and the Private Exchange Notes shall be
issued under (i) the Indenture or (ii) an indenture identical in all material
respects to the Indenture and which, in either case, has been qualified under
the TIA or is exempt from such qualification and shall provide that the Exchange
Notes shall not be subject to the transfer restrictions set forth in the
Indenture. The Indenture or such indenture shall provide that the Exchange
Notes, the Private Exchange Notes and the Securities shall vote and consent
together on all matters as one class and that none of the Exchange Notes, the
Private Exchange Notes or the Securities will have the right to vote or consent
as a separate class on any matter.

                  (c) If, (i) because of any change in law or in currently
prevailing interpretations of the staff of the SEC, the Issuers are not
permitted to effect the Exchange Offer, (ii) the Exchange Offer is not completed
on or prior to the 150th day after the Issue Date, (iii) any holder of Private
Exchange Notes so requests after the consummation of the Private Exchange, or
(iv) in the case of any Holder that participates in the Exchange Offer, such
Holder does not receive Exchange Notes on the date of the exchange that may be
sold without restriction under state and federal securities laws (other than due
solely to the status of such Holder as an affiliate of the Issuers under Rule
405) and such Holder so requests, then in the case of each of clauses (i) to and
including (iv) of this sentence, the Issuers shall promptly deliver to the
Holders and the Trustee written notice thereof (the "Shelf Notice") and shall
file a Shelf Registration pursuant to Section 3 hereof.

               3. Shelf Registration

                  If at any time a Shelf Notice is delivered as contemplated by
Section 2(c) hereof, then:

                  (a) Shelf Registration. The Issuers shall as promptly as
practicable file with the SEC a Registration Statement for an offering to be
made on a continuous basis pursuant to Rule 415 covering all of the Registrable
Notes (the "Shelf Registration"). If the Issuers shall not have yet filed an
Exchange Offer Registration Statement, the Issuers shall use their best



<PAGE>   11



                                      -10-


efforts to file with the SEC the Shelf Registration on or prior to the Filing
Date. The Shelf Registration shall be on Form S-1 or another appropriate form
permitting registration of such Registrable Notes for resale by Holders in the
manner or manners designated by them (including, without limitation, one or more
underwritten offerings). The Issuers shall not permit any securities other than
the Registrable Notes and the Guarantees to be included in the Shelf
Registration.

                  The Issuers shall use their reasonable best efforts to cause
the Shelf Registration to be declared effective under the Securities Act on or
prior to the Effectiveness Date and to keep the Shelf Registration continuously
effective under the Securities Act until the date that is two years from the
Issue Date (the "Effectiveness Period"), or such shorter period ending when all
Registrable Notes covered by the Shelf Registration have been sold in the manner
set forth and as contemplated in the Shelf Registration; provided, however, that
no Holder shall be entitled to be named as a selling securityholder in the Shelf
Registration or to use the Prospectus forming a part thereof for resales of
Registrable Securities unless such Holder has provided the Issuers within 10
Business Days after receipt of a request therefor, with the information required
by the first two paragraphs which follow Section 5(t), as applicable; and
provided, further, however, that the Effectiveness Period in respect of the
Shelf Registration shall be extended to the extent required to permit dealers to
comply with the applicable prospectus delivery requirements of Rule 174 under
the Securities Act and as otherwise provided therein.

                  (b) Withdrawal of Stop Orders. If the Shelf Registration
ceases to be effective for any reason at any time during the Effectiveness
Period (other than because of the sale of all of the securities registered
thereunder), the Issuers shall use their reasonable best efforts to obtain the
prompt withdrawal of any order suspending the effectiveness thereof.

                  (c) Supplements and Amendments. The Issuers shall promptly
supplement and amend the Shelf Registration if required by the rules,
regulations or instructions applicable to the registration form used for such
Shelf Registration, if required by the Securities Act, or if reasonably
requested by the Holders of a majority in aggregate principal amount of the
Registrable Notes covered by such Registration Statement (provided all such
requesting Holders have provided the Issuers within 10 Business Days after
receipt of a request therefor, with the information required by the first two
paragraphs which follow Section 5(t)) or by any underwriter of such Registrable
Notes.

               4. Additional Interest

                  (a) The Issuers and the Initial Purchaser agree that the
Holders will suffer damages if the Issuers fail to fulfill their obligations
under Section 2 or Section 3 hereof and that it would not be feasible to
ascertain the extent of such damages with precision. Accordingly,


<PAGE>   12


                                      -11-


the Issuers agree to pay, as liquidated damages, additional interest on the
Notes ("Additional Interest") under the circumstances and to the extent set
forth below (each of which shall be given independent effect):

                  (i) if (A) neither the Exchange Offer Registration Statement
          nor the Shelf Registration has been filed on or prior to the
          applicable Filing Date or (B) notwithstanding that the Issuers have
          consummated or will consummate the Exchange Offer, the Issuers are
          required to file a Shelf Registration and such Shelf Registration is
          not filed on or prior to the Filing Date applicable thereto, then,
          commencing on the day after any such lapsed Filing Date, Additional
          Interest shall accrue on the principal amount of the Securities at a
          rate of 0.25% per annum for the first 90 days immediately following
          each such lapsed Filing Date, and such Additional Interest rate shall
          increase by an additional 0.25% per annum at the beginning of each
          subsequent 90-day period; or

                  (ii) if (A) neither the Exchange Offer Registration Statement
          nor the Shelf Registration is declared effective by the SEC on or
          prior to the relevant Effectiveness Date or (B) notwithstanding that
          the Issuers have consummated or will consummate the Exchange Offer,
          the Issuers are required to file a Shelf Registration and such Shelf
          Registration is not declared effective by the SEC on or prior to the
          Effectiveness Date in respect of such Shelf Registration, then,
          commencing on the day after such Effectiveness Date, Additional
          Interest shall accrue on the principal amount of the Securities at a
          rate of 0.25% per annum for the first 90 days immediately following
          the day after such Effectiveness Date, and such Additional Interest
          rate shall increase by an additional 0.25% per annum at the beginning
          of each subsequent 90-day period; or

                  (iii) if (A) the Issuers have not exchanged Exchange Notes for
          all Securities validly tendered in accordance with the terms of the
          Exchange Offer on or prior to the 150th day after the Issue Date or
          (B) if applicable, a Shelf Registration has been declared effective
          and such Shelf Registration ceases to be effective at any time during
          the Effectiveness Period, then Additional Interest shall accrue on the
          principal amount of the Securities at a rate of 0.25% per annum for
          the first 90 days commencing on (x) the 36th day after such effective
          date, in the case of (A) above, or (y) the day such Shelf Registration
          ceases to be effective in the case of (B) above, and such Additional
          Interest rate shall increase by an additional 0.25% per annum at the
          beginning of each such subsequent 90-day period;

provided, however, that the Additional Interest rate on the Notes may not exceed
at any one time in the aggregate 1.50% per annum; provided, further, however,
that (1) upon the filing of the applicable Exchange Offer Registration Statement
or the Shelf Registration as required hereunder (in the case of clause (i) above
of this Section 4(a)), (2) upon the effectiveness of


<PAGE>   13



                                      -12-


the Exchange Offer Registration Statement or the Shelf Registration Statement as
required hereunder (in the case of clause (ii) of this Section 4), or (3) upon
the exchange of the applicable Exchange Notes for all Securities tendered (in
the case of clause (iii)(A) of this Section 4), or upon the effectiveness of the
Shelf Registration Statement which had ceased to remain effective (in the case
of clause (iii)(B) of this Section 4), Additional Interest on the Notes in
respect of which such events relate as a result of such clause (or the relevant
subclause thereof), as the case may be, shall cease to accrue and the interest
rate borne by the Registrable Notes will be reduced to the original interest
rate.

                  (b) The Issuers shall notify the Trustee within one Business
Day after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "Event Date"). Any amounts of
Additional Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section
4 will be payable in cash semiannually on each April 15 and October 15 (to the
holders of record on the April 1 and October 1 immediately preceding such
dates), commencing with the first such date occurring after any such Additional
Interest commences to accrue. The amount of Additional Interest will be
determined by multiplying the applicable Additional Interest rate by the
principal amount of the Registrable Notes, multiplied by a fraction, the
numerator of which is the number of days such Additional Interest rate was
applicable during such period (determined on the basis of a 360-day year
comprised of twelve 30-day months and, in the case of a partial month, the
actual number of days elapsed), and the denominator of which is 360.

               5. Registration Procedures

                  In connection with the filing of any Registration Statement
pursuant to Section 2 or 3 hereof, the Issuers shall effect such registrations
to permit the sale of the securities covered thereby in accordance with the
intended method or methods of disposition thereof, and pursuant thereto and in
connection with any Registration Statement filed by the Issuers hereunder each
of the Issuers shall:

                  (a) Prepare and file with the SEC prior to the Filing Date a
          Registration Statement or Registration Statements as prescribed by
          Section 2 or 3 hereof, and use its best efforts to cause each such
          Registration Statement to become effective and remain effective as
          provided herein; provided, however, that if (1) such filing is
          pursuant to Section 3 hereof, or (2) a Prospectus contained in the
          Exchange Offer Registration Statement filed pursuant to Section 2
          hereof is required to be delivered under the Securities Act by any
          Participating Broker-Dealer who seeks to sell Exchange Notes during
          the Applicable Period relating thereto, before filing any Registration
          Statement or Prospectus or any amendments or supplements thereto,
          Issuers shall furnish to, with respect to clause (1) above and only if
          so requested with respect to clause (2) above, and afford the Holders
          of the Registrable Notes included in such Registration Statement


<PAGE>   14



                                      -13-


          (with respect to a Registration Statement filed pursuant to Section 3
          hereof) or each such Participating Broker-Dealer (with respect to any
          such Registration Statement), as the case may be, their counsel and
          the managing underwriters, if any, a reasonable opportunity to review
          copies of all such documents (including copies of any documents to be
          incorporated by reference therein and all exhibits thereto) proposed
          to be filed (in each case at least three Business Days prior to such
          filing or such later date as is reasonable under the circumstances).
          The Issuers shall not file any Registration Statement or Prospectus or
          any amendments or supplements thereto if the Holders of a majority in
          aggregate principal amount of the Registrable Notes included in such
          Registration Statement, or any such Participating Broker-Dealer, as
          the case may be, their counsel, or the managing underwriters, if any,
          shall reasonably object on a timely basis; provided, however, that if
          the Issuers' failure to file a Registration Statement or Prospectus,
          or any amendments or supplements thereto, in the applicable time
          periods as set forth in Section 4, is based upon such an objection, no
          Additional Interest shall accrue.

                  (b) Prepare and file with the SEC such amendments and
          post-effective amendments to each Shelf Registration Statement or
          Exchange Offer Registration Statement, as the case may be, as may be
          necessary to keep such Shelf Registration Statement or Exchange Offer
          Registration Statement continuously effective for the Effectiveness
          Period or the Applicable Period, respectively; cause the related
          Prospectus to be supplemented by any Prospectus supplement required by
          applicable law, and as so supplemented to be filed pursuant to Rule
          424; and comply with the provisions of the Securities Act and the
          Exchange Act applicable to each of them with respect to the
          disposition of all securities covered by such Registration Statement
          as so amended or in such Prospectus as so supplemented and with
          respect to the subsequent resale of any securities being sold by a
          Participating Broker-Dealer covered by any such Prospectus.

                  (c) If (1) a Shelf Registration is filed pursuant to Section 3
          hereof, or (2) a Prospectus contained in the Exchange Offer
          Registration Statement filed pursuant to Section 2 hereof is required
          to be delivered under the Securities Act by any Participating
          Broker-Dealer who seeks to sell Exchange Notes during the Applicable
          Period relating thereto from whom any Issuer has received written
          notice that it will be a Participating Broker-Dealer in the Exchange
          Offer, notify the selling Holders of Registrable Notes (with respect
          to a Registration Statement filed pursuant to Section 3 hereof), or
          each such Participating Broker-Dealer (with respect to any such
          Registration Statement), as the case may be, their counsel and the
          managing underwriters, if any, promptly, and confirm such notice in
          writing, (i) when a Prospectus or any Prospectus supplement or
          post-effective amendment has been filed, and, with respect to a
          Registration Statement or any post-effective amendment, when the same
          has become effective


<PAGE>   15


                                      -14-


          under the Securities Act (including in such notice a written statement
          that any Holder may, upon written request, obtain, at the sole expense
          of the Issuers, one conformed copy of such Registration Statement or
          post-effective amendment including financial statements and schedules,
          documents incorporated or deemed to be incorporated by reference and
          exhibits), (ii) of the issuance by the SEC of any stop order
          suspending the effectiveness of a Registration Statement or of any
          order preventing or suspending the use of any preliminary prospectus
          or the initiation of any proceedings for that purpose, (iii) of the
          receipt by any Issuer of any notification with respect to the
          suspension of the qualification or exemption from qualification of a
          Registration Statement or any of the Registrable Notes or the Exchange
          Notes to be sold by any Participating Broker-Dealer for offer or sale
          in any jurisdiction, or the initiation or threatening of any
          proceeding for such purpose, (iv) of the happening of any event, the
          existence of any condition or any information becoming known that
          makes any statement made in such Registration Statement or related
          Prospectus or any document incorporated or deemed to be incorporated
          therein by reference untrue in any material respect or that requires
          the making of any changes in or amendments or supplements to such
          Registration Statement, Prospectus or documents so that, in the case
          of the Registration Statement, it will not contain any untrue
          statement of a material fact or omit to state any material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, and that in the case of the Prospectus, it
          will not contain any untrue statement of a material fact or omit to
          state any material fact required to be stated therein or necessary to
          make the statements therein, in light of the circumstances under which
          they were made, not misleading, and (v) of the Issuers' determination
          that a post-effective amendment to a Registration Statement would be
          appropriate.

                  (d) Use its reasonable best efforts to prevent the issuance
          of any order suspending the effectiveness of a Registration Statement
          or of any order preventing or suspending the use of a Prospectus or
          suspending the qualification (or exemption from qualification) of any
          of the Registrable Notes or the Exchange Notes to be sold by any
          Participating Broker-Dealer, for sale in any jurisdiction, and, if any
          such order is issued, to use its reasonable best efforts to obtain the
          withdrawal of any such order at the earliest practicable moment.

                  (e) If a Shelf Registration is filed pursuant to Section 3 and
          if requested during the Effectiveness Period by the managing
          underwriter or underwriters (if any), the Holders of a majority in
          aggregate principal amount of the Registrable Notes being sold in
          connection with an underwritten offering or any Participating
          Broker-Dealer, (i) as promptly as practicable incorporate in a
          prospectus supplement or post-effective amendment such information as
          the managing underwriter or underwriters (if any),


<PAGE>   16


                                      -15-

          such Holders, any Participating Broker-Dealer or counsel for any of
          them reasonably request to be included therein, (ii) make all required
          filings of such prospectus supplement or such post-effective amendment
          as soon as practicable after any Issuer has received notification of
          the matters to be incorporated in such prospectus supplement or
          post-effective amendment, and (iii) supplement or make amendments to
          such Registration Statement.

                  (f) If (1) a Shelf Registration is filed pursuant to Section 3
          hereof, or (2) a Prospectus contained in the Exchange Offer
          Registration Statement filed pursuant to Section 2 hereof is required
          to be delivered under the Securities Act by any Participating
          Broker-Dealer who seeks to sell Exchange Notes during the Applicable
          Period, if so requested by a selling Holder of Registrable Notes or a
          Participating Broker-Dealer, as the case may be, furnish to each
          selling Holder of Registrable Notes who so requests, (with respect to
          a Registration Statement filed pursuant to Section 3 hereof) and to
          each such Participating Broker-Dealer who so requests (with respect to
          any such Registration Statement) and to their respective counsel and
          each managing underwriter, if any, at the sole expense of the Issuers,
          one conformed copy of the Registration Statement or Registration
          Statements and each post-effective amendment thereto, including
          financial statements and schedules, and, if requested, all documents
          incorporated or deemed to be incorporated therein by reference and all
          exhibits.

                  (g) If (1) a Shelf Registration is filed pursuant to Section 3
          hereof, or (2) a Prospectus contained in the Exchange Offer
          Registration Statement filed pursuant to Section 2 hereof is required
          to be delivered under the Securities Act by any Participating
          Broker-Dealer who seeks to sell Exchange Notes during the Applicable
          Period, deliver to each selling Holder of Registrable Notes (with
          respect to a Registration Statement filed pursuant to Section 3
          hereof), or each such Participating Broker-Dealer (with respect to any
          such Registration Statement), as the case may be, their respective
          counsel, and the underwriters, if any, at the sole expense of the
          Issuers, as many copies of the Prospectus or Prospectuses (including
          each form of preliminary prospectus) and each amendment or supplement
          thereto and any documents incorporated by reference therein as such
          Persons may reasonably request; and, subject to the last paragraph of
          this Section 5, the Issuers hereby consent to the use of such
          Prospectus and each amendment or supplement thereto by each of the
          selling Holders of Registrable Notes or each such Participating
          Broker-Dealer, as the case may be, and the underwriters or agents, if
          any, and dealers, if any, in connection with the offering and sale of
          the Registrable Notes covered by, or the sale by Participating
          Broker-Dealers of the Exchange Notes pursuant to, such Prospectus and
          any amendment or supplement thereto.

                  (h) Prior to any public offering of Registrable Notes or
          Exchange Notes or any delivery of a Prospectus contained in the
          Exchange Offer Registration Statement


<PAGE>   17



                                      -16-


          by any Participating Broker-Dealer who seeks to sell Exchange Notes
          during the Applicable Period, use its reasonable best efforts to
          register or qualify, and to cooperate with the selling Holders of
          Registrable Notes or each such Participating Broker-Dealer, as the
          case may be, the managing underwriter or underwriters, if any, and
          their respective counsel in connection with the registration or
          qualification (or exemption from such registration or qualification)
          of such Registrable Notes for offer and sale under the securities or
          Blue Sky laws of such jurisdictions within the United States as any
          selling Holder, Participating Broker-Dealer, or the managing
          underwriter or underwriters reasonably request in writing; provided,
          however, that where Exchange Notes held by Participating
          Broker-Dealers or Registrable Notes are offered other than through an
          underwritten offering, the Issuers agree to cause their counsel to
          perform Blue Sky investigations and file registrations and
          qualifications required to be filed pursuant to this Section 5(h),
          keep each such registration or qualification (or exemption therefrom)
          effective during the period such Registration Statement is required to
          be kept effective and do any and all other acts or things necessary or
          advisable to enable the disposition in such jurisdictions of the
          Exchange Notes held by Participating Broker-Dealers or the Registrable
          Notes covered by the applicable Registration Statement; provided,
          however, that no Issuer shall be required to (A) qualify generally to
          do business in any jurisdiction where it is not then so qualified, (B)
          take any action that would subject it to general service of process in
          any such jurisdiction where it is not then so subject, (C) subject
          itself to taxation in excess of a nominal dollar amount in any such
          jurisdiction where it is not then so subject, or (D) make any material
          changes to its respective certificate of incorporation or bylaws or
          any agreement between it and its stockholders.

                  (i) If a Shelf Registration is filed pursuant to Section 3
          hereof, cooperate with the selling Holders of Registrable Notes and
          the managing underwriter or underwriters, if any, to facilitate the
          timely preparation and delivery of certificates representing
          Registrable Notes to be sold, which certificates shall not bear any
          restrictive legends and shall be in a form eligible for deposit with
          The Depository Trust Company; and enable such Registrable Notes to be
          in such denominations (subject to applicable requirements contained in
          the Indenture) and registered in such names as the managing
          underwriter or underwriters, if any, or Holders may request.

                  (j) Use their reasonable best efforts to cause the Registrable
          Notes covered by the Registration Statement to be registered with or
          approved by such other governmental agencies or authorities as may be
          necessary to enable the seller or sellers thereof or the underwriter
          or underwriters, if any, to consummate the disposition of such
          Registrable Notes, except as may be required solely as a consequence
          of the nature of such selling Holder's business, in which case the
          Issuers will cooperate in all



<PAGE>   18


                                      -17-


          respects with the filing of such Registration Statement and the
          granting of such approvals.

                  (k) If (1) a Shelf Registration is filed pursuant to Section 3
          hereof, or (2) a Prospectus contained in the Exchange Offer
          Registration Statement filed pursuant to Section 2 hereof is required
          to be delivered under the Securities Act by any Participating
          Broker-Dealer who seeks to sell Exchange Notes during the Applicable
          Period, upon the occurrence of any event contemplated by paragraph
          5(c)(iv), 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable
          prepare and (subject to Section 5(a) hereof) file with the SEC, at the
          sole expense of the Issuers, a supplement or post-effective amendment
          to the Registration Statement or a supplement to the related
          Prospectus or any document incorporated or deemed to be incorporated
          therein by reference, or file any other required document so that, as
          thereafter delivered to the purchasers of the Registrable Notes being
          sold thereunder (with respect to a Registration Statement filed
          pursuant to Section 3 hereof) or to the purchasers of the Exchange
          Notes to whom such Prospectus will be delivered by a Participating
          Broker-Dealer (with respect to any such Registration Statement), any
          such Prospectus will not contain an untrue statement of a material
          fact or omit to state a material fact required to be stated therein or
          necessary to make the statements therein, in light of the
          circumstances under which they were made, not misleading.

                  (l) Prior to the effective date of the first Registration
          Statement relating to the Registrable Notes, (i) provide the Trustee
          with certificates for the Registrable Notes in a form eligible for
          deposit with The Depository Trust Company and (ii) provide a CUSIP
          number for the Registrable Notes.

                  (m) In connection with any underwritten offering of
          Registrable Notes pursuant to a Shelf Registration, enter into an
          underwriting agreement as is customary in underwritten offerings of
          debt securities similar to the Securities, and take all such other
          actions as are reasonably requested by the managing underwriter or
          underwriters in order to expedite or facilitate the registration or
          the disposition of such Registrable Notes and, in such connection, (i)
          make such representations and warranties to, and covenants with, the
          underwriters with respect to the business of the Issuers (including
          any acquired business, properties or entity, if applicable), and the
          Registration Statement, Prospectus and documents, if any, incorporated
          or deemed to be incorporated by reference therein, in each case, as
          are customarily made by issuers to underwriters in underwritten
          offerings of debt securities similar to the Securities, and confirm
          the same in writing if and when requested; (ii) obtain the written
          opinions of counsel to the Issuers, and written updates thereof in
          form, scope and substance reasonably satisfactory to the managing
          underwriter or underwriters, addressed to the underwriters covering
          the matters customarily covered in opinions requested in underwritten
          offering


<PAGE>   19


                                      -18-


          and such other matters as may be reasonably requested by the managing
          underwriter or underwriters; (iii) obtain "cold comfort" letters and
          updates thereof in form, scope and substance reasonably satisfactory
          to the managing underwriter or underwriters from the independent
          certified public accountants of the Issuers (and, if necessary, any
          other independent certified public accountants the Issuers, or of any
          business acquired by the Issuers, for which financial statements and
          financial data are, or are required to be, included or incorporated by
          reference in the Registration Statement), addressed to each of the
          underwriters, such letters to be in customary form and covering
          matters of the type customarily covered in "cold comfort" letters in
          connection with underwritten offerings of debt securities similar to
          the Securities and such other matters as reasonably requested by the
          managing underwriter or underwriters as permitted by the Statement on
          Auditing Standards No. 72; and (iv) if an underwriting agreement is
          entered into, the same shall contain indemnification provisions and
          procedures no less favorable to the sellers and underwriters, if any,
          than those set forth in Section 7 hereof (or such other provisions and
          procedures acceptable to Holders of a majority in aggregate principal
          amount of Registrable Notes covered by such Registration Statement who
          have provided the information to the Issuers as required by the
          paragraphs following Section 5(t) and the managing underwriter or
          underwriters or agents, if any). The above shall be done at each
          closing under such underwriting agreement, or as and to the extent
          required thereunder.

                  (n) If (1) a Shelf Registration is filed pursuant to Section 3
          hereof, or (2) a Prospectus contained in the Exchange Offer
          Registration Statement filed pursuant to Section 2 hereof is required
          to be delivered under the Securities Act by any Participating
          Broker-Dealer who seeks to sell Exchange Notes during the Applicable
          Period, make available for inspection by any selling Holder of such
          Registrable Notes being sold (with respect to a Registration Statement
          filed pursuant to Section 3 hereof), or each such Participating
          Broker-Dealer, as the case may be, any underwriter participating in
          any such disposition of Registrable Notes, if any, and any attorney,
          accountant or other agent retained by any such selling Holder or each
          such Participating Broker-Dealer (with respect to any such
          Registration Statement), as the case may be, or underwriter
          (collectively, the "Inspectors"), upon written request, at the offices
          where normally kept, during reasonable business hours and upon
          reasonable advance notice, all pertinent financial and other records,
          pertinent corporate documents and instruments of the Issuers and
          subsidiaries of the Issuers (collectively, the "Records"), as shall be
          reasonably necessary to enable them to exercise any applicable due
          diligence responsibilities, and cause the officers, directors and
          employees of the Issuers and any of their respective subsidiaries to
          supply all information ("Information") reasonably requested by any
          such Inspector in connection with such due diligence responsibilities;
          provided, however that each Inspector shall agree in writing that it
          will keep the Records

<PAGE>   20



                                      -19-


          and Information confidential and that it will not disclose any of the
          Records that the any Issuer determines, in good faith, to be
          confidential and notifies the Inspectors in writing are confidential
          unless (i) the Issuers determine in their sole discretion on advice of
          counsel that the disclosure of such Records or Information is
          necessary to avoid or correct a misstatement or omission in such
          Registration Statement or Prospectus, (ii) the release of such Records
          or Information is ordered pursuant to a subpoena or other order from a
          court of competent jurisdiction, or (iii) the information in such
          Records or Information has been made generally available to the public
          other than by an Inspector or an "affiliate" (as defined in Rule 405)
          thereof; provided, however, that prior notice shall be provided as
          soon as practicable to the any Issuer of the potential disclosure of
          any information by such Inspector pursuant to clause (ii) of this
          sentence to permit the Issuers to obtain a protective order (or waive
          the provisions of this paragraph (o)) and that such Inspector shall
          take such actions as are reasonably necessary to protect the
          confidentiality of such information (if practicable) to the extent
          such action is otherwise not inconsistent with, an impairment of or in
          derogation of the rights and interests of the Holder or any Inspector.

                  (o) Provide an indenture trustee for the Registrable Notes or
          the Exchange Notes, as the case may be, and cause the Indenture or the
          trust indenture provided for in Section 2(a) hereof, as the case may
          be, to be qualified under the TIA not later than the effective date of
          the first Registration Statement relating to the Registrable Notes;
          and in connection therewith, cooperate with the trustee under any such
          indenture and the Holders of the Registrable Notes, to effect such
          changes (if any) to such indenture as may be required for such
          indenture to be so qualified in accordance with the terms of the TIA;
          and execute, and use their best efforts to cause such trustee to
          execute, all documents as may be required to effect such changes, and
          all other forms and documents required to be filed with the SEC to
          enable such indenture to be so qualified in a timely manner.

                  (p) Comply with all applicable rules and regulations of the
          SEC and make generally available to its securityholders with regard to
          any applicable Registration Statement, a consolidated earnings
          statement satisfying the provisions of Section 11(a) of the Securities
          Act and Rule 158 thereunder (or any similar rule promulgated under the
          Securities Act) no later than 45 days after the end of any fiscal
          quarter (or 90 days after the end of any 12-month period if such
          period is a fiscal year) (i) commencing at the end of any fiscal
          quarter in which Registrable Notes are sold to underwriters in a firm
          commitment or best efforts underwritten offering and (ii) if not sold
          to underwriters in such an offering, commencing on the first day of
          the first fiscal quarter of the Company, after the effective date of a
          Registration Statement (as such term is defined


<PAGE>   21



                                      -20-


          in paragraph (c) of Rule 158 under the Securities Act), which
          statements shall cover said 12-month periods.

                  (q) Upon consummation of the Exchange Offer or a Private
          Exchange, if so requested by the Trustee, obtain an opinion of counsel
          to the Issuers, in a form customary for underwritten transactions,
          addressed to the Trustee for the benefit of all Holders of Registrable
          Notes participating in the Exchange Offer or the Private Exchange, as
          the case may be, that the Exchange Notes or Private Exchange Notes, as
          the case may be, the related Guarantee and the related indenture
          constitute legal, valid and binding obligations of the Issuers,
          enforceable against the Issuers in accordance with their respective
          terms, subject to customary exceptions and qualifications.

                  (r) If the Exchange Offer or a Private Exchange is to be
          consummated, upon delivery of the Registrable Notes by Holders to the
          Company (or to such other Person as directed by the Issuers), in
          exchange for the Exchange Notes or the Private Exchange Notes, as the
          case may be, the Issuers shall mark, or cause to be marked, on such
          Registrable Notes that such Registrable Notes are being cancelled in
          exchange for the Exchange Notes or the Private Exchange Notes, as the
          case may be; in no event shall such Registrable Notes be marked as
          paid or otherwise satisfied.

                  (s) Cooperate with each seller of Registrable Notes covered by
          any Registration Statement and each underwriter, if any, participating
          in the disposition of such Registrable Notes and their respective
          counsel in connection with any filings required to be made with the
          National Association of Securities Dealers, Inc. (the "NASD").

                  (t) Use its reasonable best efforts to take all other steps
          necessary to effect the registration of the Exchange Notes and/or
          Registrable Notes covered by a Registration Statement contemplated
          hereby.

                  No Holder of Registrable Notes as to which any registration is
being effected may include any such Registrable Securities in any Shelf
Registration pursuant to this Agreement unless and until such Holder furnishes
to the Issuers in writing, the information regarding such seller and the
distribution of such Registrable Notes as the Issuers may, from time to time,
reasonably request. The Issuers may exclude from such registration the
Registrable Notes of any seller so long as such seller fails to furnish such
information within a reasonable time (but no later than 10 Business Days) after
receiving such request. Each seller as to which any Shelf Registration is being
effected agrees to furnish promptly to the Issuers all information required to
be disclosed in order to make the information previously furnished to the
Issuers by such seller not materially misleading.


<PAGE>   22



                                      -21-



                  In the event of a Shelf Registration, in addition to the
information required to be provided by each selling Holder in accordance with
the preceding paragraph, the Company may require such selling Holder to furnish
to the Company such additional information regarding such selling Holder and
such selling Holder's intended method of distribution of Registrable Notes as
may be required in order to comply with the Securities Act. Each such selling
Holder agrees to notify the Company as promptly as practicable of any inaccuracy
or change in information previously furnished by such selling Holder to the
Company or of the occurrence of any event in either case as a result of which
any prospectus relating to such Shelf Registration contains or would contain an
untrue statement of a material fact regarding such selling Holder or such
selling Holder's intended method of disposition of such Registrable Notes or
omits to state any material fact regarding such selling Holder or such selling
Holder's intended method of disposition of such Registrable Notes required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing, and promptly to furnish to the Company
any additional information required to correct and update any previously
furnished information or required so that such prospectus shall not contain,
with respect to such selling Holder or the disposition of such Registrable
Notes, an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing.

                  If any such Registration Statement refers to any Holder by
name or otherwise as the holder of any securities of the Company, then such
Holder shall have the right to require (i) the insertion therein of language, in
form and substance reasonably satisfactory to such Holder, to the effect that
the holding by such Holder of such securities is not to be construed as a
recommendation by such Holder of the investment quality of the securities
covered thereby and that such holding does not imply that such Holder will
assist in meeting any future financial requirements of the Company, or (ii) in
the event that such reference to such Holder by name or otherwise is not
required by the Securities Act or any similar federal statute then in force, the
deletion of the reference to such Holder in any amendment or supplement to the
Registration Statement filed or prepared subsequent to the time that such
reference ceases to be required.

                  Each Holder of Registrable Notes and each Participating
Broker-Dealer agrees by its acquisition of such Registrable Notes or Exchange
Notes to be sold by such Participating Broker-Dealer, as the case may be, that,
upon actual receipt of any notice from the Company of the happening of any event
of the kind described in Section 5(c)(ii), 5(c)(iii), 5(c)(iv), or 5(c)(v),
hereof, such Holder will forthwith discontinue disposition of such Registrable
Notes covered by such Registration Statement or Prospectus or Exchange Notes to
be sold by such Holder or Participating Broker-Dealer, as the case may be, until
such Holder's or Participating Broker-Dealer's receipt of the copies of the
supplemented or amended Prospectus contemplated


<PAGE>   23



                                      -22-


by Section 5(k) hereof, or until it is advised in writing (the "Advice") by the
Issuers that the use of the applicable Prospectus may be resumed, and has
received copies of any amendments or supplements thereto. In the event that the
Issuers shall give any such notice, the Applicable Period shall be extended by
the number of days during such periods from and including the date of the giving
of such notice to and including the date when each seller of Registrable Notes
covered by such Registration Statement or Exchange Notes to be sold by such
Participating Broker-Dealer, as the case may be, shall have received (x) the
copies of the supplemented or amended Prospectus contemplated by Section 5(k)
hereof or (y) the Advice. Each holder of Registrable Notes agrees that the
Company has the right to require such holders to discontinue dispositions for up
to 90 days if the Company gives notice of a material non-public acquisition or
event; provided, however, that each holder shall be subject to the hold-back
restrictions of this Section 5 only twice during the term of this Agreement.
During any such discontinuance, no Additional Interest shall accrue or otherwise
be payable to the Holders.

               6. Registration Expenses

                  All fees and expenses incident to the performance of or
compliance with this Agreement by the Issuers (other than any underwriting
discounts or commissions) shall be borne by the Issuers, whether or not the
Exchange Offer Registration Statement or any Shelf Registration is filed or
becomes effective or the Exchange Offer is consummated, including, without
limitation, (i) all registration and filing fees (including, without limitation,
(A) fees with respect to filings required to be made with the NASD in connection
with an underwritten offering and (B) reasonable fees and expenses of compliance
with state securities or Blue Sky laws (including, without limitation, fees and
disbursements of counsel in connection with Blue Sky qualifications of the
Registrable Notes or Exchange Notes and determination of the eligibility of the
Registrable Notes or Exchange Notes for investment under the laws of such
jurisdictions (x) where the holders of Registrable Notes are located, in the
case of the Exchange Notes, or (y) as provided in Section 5(h) hereof, in the
case of Registrable Notes or Exchange Notes to be sold by a Participating
Broker-Dealer during the Applicable Period)), (ii) printing expenses, including,
without limitation, expenses of printing certificates for Registrable Notes or
Exchange Notes in a form eligible for deposit with The Depository Trust Company
and of printing prospectuses if the printing of prospectuses is requested by the
managing underwriter or underwriters, if any, by the Holders of a majority in
aggregate principal amount of the Registrable Notes included in any Registration
Statement or in respect of Registrable Notes or Exchange Notes to be sold by any
Participating Broker-Dealer during the Applicable Period, as the case may be,
(iii) reasonable messenger, telephone and delivery expenses relating to the
offering, sale or delivery of Securities and the preparation of documents
referenced in clause (xi) below, (iv) fees and disbursements of counsel for the
Issuers and, in case of a Shelf Registration, reasonable fees and disbursements
of not more than one special

                                      -23-


counsel for all of the sellers of Registrable Notes (exclusive of any counsel
retained pursuant to Section 7 hereof), (v) fees and disbursements of all
independent certified public accountants referred to in Section 5(m)(iii) hereof
(including, without limitation, the expenses of any special audit and "cold
comfort" letters required by or incident to such performance), (vi) Securities
Act liability insurance, if the Issuers desire such insurance, (vii) fees and
expenses of all other Persons retained by the Issuers, (viii) internal expenses
of the Issuers (including, without limitation, all salaries and expenses of
officers and employees of the Issuers performing legal or accounting duties),
(ix) the expense of any annual audit, (x) any fees and expenses incurred in
connection with the listing of the securities to be registered on any securities
exchange, if applicable, and (xi) the expenses relating to printing, word
processing and distributing all Registration Statements, underwriting
agreements, indentures and any other documents necessary in order to comply with
this Agreement.

               7. Indemnification

                  (a) Each of the Issuers, jointly and severally, agrees to
indemnify and hold harmless each Holder of Registrable Notes and each
Participating Broker-Dealer selling Exchange Notes during the Applicable Period,
the affiliates, officers, directors, representatives, employees and agents of
each such Person, and each Person, if any, who controls any such Person within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each, a "Participant"), from and against any and all losses,
claims, damages, judgments, liabilities and expenses (including, without
limitation, the legal fees and other expenses actually incurred in connection
with any suit, action or proceeding or any claim asserted) caused by, arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment thereto)
or Prospectus (as amended or supplemented if any of the Issuers shall have
furnished any amendments or supplements thereto) or any preliminary prospectus,
or caused by, arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the case of the Prospectus in light of the
circumstances under which they were made, not misleading, except (i) insofar as
such losses, claims, damages or liabilities are caused by any untrue statement
or omission or alleged untrue statement or omission made in reliance upon and in
conformity with information relating to any Participant furnished to any of the
Issuers in writing by such Participant expressly for use therein and with
respect to any preliminary Prospectus, or (ii) to the extent that any such loss,
claim, damage or liability arises solely from the fact that any Participant sold
Notes to a person to whom there was not sent or given a copy of the Prospectus
(as amended or supplemented) at or prior to the written confirmation of such
sale if the Issuers shall have previously furnished copies thereof to the
Participant in accordance herewith and the Prospectus (as so amended or
supplemented) would have corrected any such untrue statement or omission.



<PAGE>   25



                                      -24-


                  (b) Each Participant agrees, severally and not jointly, to
indemnify and hold harmless the Issuers, their respective affiliates, officers,
directors, representatives, employees and agents of each Issuer and each Person
who controls each Issuer within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act to the same extent (but on a several, and not
joint, basis) as the foregoing indemnity from the Issuers to each Participant,
but only with reference to information relating to such Participant furnished to
the Issuers in writing by such Participant expressly for use in any Registration
Statement or Prospectus, any amendment or supplement thereto, or any preliminary
prospectus. The liability of any Participant under this paragraph shall in no
event exceed the proceeds received by such Participant from sales of Registrable
Notes or Exchange Notes giving rise to such obligations.

                  (c) If any suit, action, proceeding (including any
governmental or regulatory investigation), claim or demand shall be brought or
asserted against any Person in respect of which indemnity may be sought pursuant
to either of the two preceding paragraphs, such Person (the "Indemnified
Person") shall promptly notify the Persons against whom such indemnity may be
sought (the "Indemnifying Persons") in writing, and the Indemnifying Persons,
upon request of the Indemnified Person, shall retain counsel reasonably
satisfactory to the Indemnified Person to represent the Indemnified Person and
any others the Indemnifying Persons may reasonably designate in such proceeding
and shall pay the fees and expenses actually incurred by such counsel related to
such proceeding; provided, however, that the failure to so notify the
Indemnifying Persons (i) will not relieve it from any liability under paragraph
(a) or (b) above unless and to the extent such failure results in material
prejudice to any Indemnifying Person and (ii) will not, in any event, relieve
the Indemnifying Person from any other obligations to any Indemnified Person. In
any such proceeding, any Indemnified Person shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such Indemnified Person unless (i) the Indemnifying Persons and the
Indemnified Person shall have mutually agreed to the contrary, (ii) the
Indemnifying Persons shall have failed within a reasonable period of time to
retain counsel reasonably satisfactory to the Indemnified Person, or (iii) the
named parties in any such proceeding (including any impleaded parties) include
both any Indemnifying Person and the Indemnified Person or any affiliate thereof
and representation of both parties by the same counsel would be inappropriate
due to actual or potential conflicting interests between them. It is understood
that the Indemnifying Persons shall not, in connection with such proceeding or
separate but substantially similar related proceeding in the same jurisdiction
arising out of the same general allegations, be liable for the fees and expenses
of more than one separate firm (in addition to any reasonably necessary local
counsel) for all Indemnified Persons, and that all such fees and expenses shall
be reimbursed promptly as they are incurred, subject to an undertaking by such
Indemnified Persons that all such amounts to which any Indemnified Person is not
entitled pursuant to this Section 7, as determined by a final non-appealable
judicial determination, shall be returned promptly to the relevant Indemnifying
Persons. Any such separate firm for the Participants

<PAGE>   26


                                      -25-



and such control Persons of Participants shall be designated in writing by
Participants who sold a majority in interest of Registrable Notes and Exchange
Notes sold by all such Participants and shall be reasonably acceptable to the
Company and any such separate firm for the Issuers, their affiliates, officers,
directors, representatives, employees and agents and such control Persons of
such Issuer shall be designated in writing by such Issuer and shall be
reasonably acceptable to the Holders.

                  The Indemnifying Persons shall not be liable for any
settlement of any proceeding effected without its prior written consent (which
consent shall not be unreasonably withheld or delayed), but if settled with such
consent or if there be a final non-appealable judgment for the plaintiff for
which the Indemnified Person is entitled to indemnification pursuant to this
Agreement, each of the Indemnifying Persons agrees to indemnify and hold
harmless each Indemnified Person from and against any loss or liability by
reason of such settlement or judgment. No Indemnifying Person shall, without the
prior written consent of the Indemnified Persons (which consent shall not be
unreasonably withheld or delayed), effect any settlement or compromise of any
pending or threatened proceeding in respect of which any Indemnified Person is
or could have been a party, or indemnity could have been sought hereunder by
such Indemnified Person, unless such settlement (A) includes an unconditional
written release of such Indemnified Person, in form and substance reasonably
satisfactory to such Indemnified Person, from all liability on claims that are
the subject matter of such proceeding and (B) does not include any statement as
to an admission of fault, culpability or failure to act by or on behalf of such
Indemnified Person.

                  (d) If the indemnification provided for in Section 7(a) or
(b) is for any reason unavailable to, or insufficient to hold harmless, an
Indemnified Person in respect of any losses, claims, damages or liabilities
referred to therein, then each Indemnifying Person under such subsections, in
lieu of indemnifying such Indemnified Person thereunder and in order to provide
for just and equitable contribution, shall contribute to the amount paid or
payable by such Indemnified Person as a result of such losses, claims, damages
or liabilities in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Person or Persons on the one hand and the Indemnified
Person or Persons on the other in connection with the statements or omissions or
alleged statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof) as well as any other relevant
equitable considerations. The relative fault of the parties shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Issuers on the one hand or
such Participant or such other Indemnified Person, as the case may be, on the
other, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission, and any other
equitable considerations appropriate in the circumstances.

                                      -26-


                  (e) The parties agree that it would not be just and equitable
if contribution pursuant to this Section 7 were determined by pro rata
allocation (even if the Participants were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages, judgments, liabilities and expenses referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any reasonable legal or other expenses actually
incurred by such Indemnified Person in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this
Section 7, in no event shall a Participant be required to contribute any amount
in excess of the amount by which proceeds received by such Participant from
sales of Registrable Notes or Exchange Notes, as the case may be, exceeds the
amount of any damages that such Participant has otherwise been required to pay
or has paid by reason of such untrue or alleged untrue statement or omission or
alleged omission. No Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

                  (f) Any losses, claims, damages, liabilities or expenses for
which an indemnified party is entitled to indemnification or contribution under
this Section 7 shall be paid by the Indemnifying Persons to the Indemnified
Person as such losses, claims, damages, liabilities or expenses are incurred,
subject to an undertaking by such Indemnified Person that all such amounts to
which such Indemnified Person is not entitled pursuant to this Section 7, as
determined by a final non-appealable judicial determination, shall be returned
promptly to the relevant Indemnifying Persons. The indemnity and contribution
agreements contained in this Section 7 and the representations and warranties of
the Issuers set forth in this Agreement shall remain operative and in full force
and effect, regardless of (i) any investigation made by or on behalf of any
Holder or any person who controls a Holder, an Issuer, its directors, officers,
employees or agents or any person controlling an Issuer, and (ii) any
termination of this Agreement.

                  (g) The indemnity and contribution agreements contained in
this Section 7 will be in addition to any liability which the Indemnifying
Persons may otherwise have to the Indemnified Persons referred to above.

               8. Rules 144 and 144A

                  Each of the Issuers covenants and agrees that it will file the
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations adopted by the SEC thereunder in a timely manner
in accordance with the requirements of the Securities Act and the Exchange Act
and, if at any time such Issuer is not required to file such reports, such
Issuer will, upon the request of any Holder or beneficial owner of Registrable


<PAGE>   28


                                      -27-


Notes, make available such information necessary to permit sales pursuant to
Rule 144A. Each of the Issuers further covenants and agrees, for so long as any
Registrable Notes remain outstanding that it will take such further action as
any Holder of Registrable Notes may reasonably request, all to the extent
required from time to time to enable such holder to sell Registrable Notes
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144(k) under the Securities Act and Rule 144A.

               9. Underwritten Registrations

                  If any of the Registrable Notes covered by any Shelf
Registration are to be sold in an underwritten offering, the investment banker
or investment bankers and manager or managers that will manage the offering will
be selected by the Holders of a majority in aggregate principal amount of such
Registrable Notes included in such offering and shall be reasonably acceptable
to the Issuers.

                  No Holder of Registrable Notes may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Notes on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such underwriting arrangements.

              10. Miscellaneous

                  (a) No Inconsistent Agreements. The Issuers have not, as of
the date hereof, and the Issuers shall not, after the date of this Agreement,
enter into any agreement with respect to any of its securities that is
inconsistent with the rights granted to the Holders of Registrable Notes in this
Agreement or otherwise conflicts with the provisions hereof. The rights granted
to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Issuers' other issued
and outstanding securities under any such agreements. The Issuers will not enter
into any agreement with respect to any of their securities which will grant to
any Person piggy-back registration rights with respect to any Registration
Statement.

                  (b) Additional Amounts of Notes. The Notes are limited in
aggregate principal amount to $250,000,000, of which $125,000,000 in aggregate
principal amount was issued on April 7, 1999 and $50,000,000 in aggregate
principal amount will be issued on the date hereof. Additional amounts of Notes
may be issued in one or more series from time to time under the Indenture
(collectively "Additional Notes") prior to the filing of any Registration
Statement. The Issuers shall provide the registration rights set forth under
this Agreement to the Initial Purchaser and any subsequent holder or holders of
such Additional Notes


<PAGE>   29


                                      -28-



and notwithstanding anything contained herein may, but are not obligated to,
include such Additional Notes in any Registration Statement filed hereunder.

                  (c) Amendments and Waivers. The provisions of this Agreement
may not be amended, modified or supplemented, and waivers or consents to
departures from the provisions hereof may not be given, otherwise than with the
prior written consent of (I) the Company, and (II)(A) the Holders of not less
than a majority in aggregate principal amount of the then outstanding
Registrable Notes and (B) in circumstances that would adversely affect the
Participating Broker-Dealers, the Participating Broker-Dealers holding not less
than a majority in aggregate principal amount of the Exchange Notes held by all
Participating Broker-Dealers; provided, however, that Section 7 and this Section
10(c) may not be amended, modified or supplemented without the prior written
consent of each Holder and each Participating Broker-Dealer (including any
person who was a Holder or Participating Broker-Dealer of Registrable Notes or
Exchange Notes, as the case may be, disposed of pursuant to any Registration
Statement) affected by any such amendment, modification or supplement.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders of Registrable Notes whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect, impair,
limit or compromise the rights of other Holders of Registrable Notes may be
given by Holders of at least a majority in aggregate principal amount of the
Registrable Notes being sold pursuant to such Registration Statement and with
the consent of the Issuers which consent shall not be unreasonably withheld.

                  (d) Notices. All notices and other communications (including,
without limitation, any notices or other communications to the Trustee) provided
for or permitted hereunder shall be made in writing by hand-delivery, registered

                  All such notices and communications shall be deemed to have
been duly given: when delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; one Business
Day after being timely delivered to a next-day air courier; and when receipt is

                  Copies of all such notices, demands or other communications
shall be concurrently delivered by the Person giving the same to the Trustee at
the address and in the manner specified in such Indenture.

                  (e) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the parties
hereto, the Holders and the Participating Broker-Dealers; provided, however,
that nothing herein shall be deemed to permit any assignment, transfer or other
disposition of Registrable Notes in violation of the terms of the Purchase
Agreement or the Indenture. If any transferee of any holder shall acquire
Registrable Notes, in any manner, whether by operation of law or otherwise, such
Registrable Notes shall be held subject to all of the terms of this Agreement,
and by taking and holding such Registrable Notes, such person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement, including the restrictions on resale set
forth in this Agreement and, if applicable, the Purchase Agreement, and such
person shall be entitled to receive the benefits hereof.

                  (f) Counterparts. This Agreement may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

                  (g) Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (H) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO
CONTRACTS MADE AND PERFORMED ENTIRELY


<PAGE>   31


                                      -30-


WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.
EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF
THE STATE OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT.

                  (i) Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

                  (j) Securities Held by the Issuers or Their Respective
Affiliates. Whenever the consent or approval of Holders of a specified
percentage of Registrable Notes is required hereunder, Registrable Notes held by
the Issuers or their respective affiliates (as such term is defined in Rule 405)
shall not be counted in determining whether such consent or approval was given
by the Holders of such required percentage.

                  (k) Third-Party Beneficiaries. Holders of Registrable Notes
and Participating Broker-Dealers are intended third-party beneficiaries of this
Agreement, and this Agreement may be enforced by such Persons.

                  (l) Entire Agreement. This Agreement, together with the
Purchase Agreement and the Indenture, is intended by the parties as a final and
exclusive statement of the agreement and understanding of the parties hereto in
respect of the subject matter contained herein and therein and any and all prior
oral or written agreements, representations, or warranties, contracts,
understandings, correspondence, conversations and memoranda between the Holders
on the one hand and the Issuers on the other, or between or among any agents,
representatives, parents, subsidiaries, affiliates, predecessors in interest or
successors in interest with respect to the subject matter hereof and thereof are
merged herein and replaced hereby.

     Re:  RailWorks Corporation--
          Registration Statement on Form S-4
          relating to $50,000,000 aggregate principal amount
          of 11 1/2% Senior Subordinated Notes Due 2009

Ladies and Gentlemen:

     We have acted as counsel for RailWorks Corporation, a Delaware corporation
(the "Company"), in connection with the preparation of a Registration Statement
of Form S-4 (the "Registration Statement") filed with the Securities and
Exchange Commission under the Securities Act of 1933, as amended, relating to
the proposed exchange of up to $50,000,000 of 11 1/2% Senior Subordinated Notes
Due 2009 of the Company (the "New Notes") for a like principal amount of the
Company's issued and outstanding 11 1/2% Senior Subordinated Notes Due 2009 (the
"Old Notes"). Certain domestic subsidiaries of the Company named in the
Indenture (defined blow)(the "Subsidiary Guarantors", and, together with the
Company, the "Registrants") have issued guarantees, on a senior subordinated
basis, of the obligations of the Company under the New Notes (the "Guarantees").

     In our capacity as such counsel, we have reviewed the Indenture (the
"Indenture") dated as of April 7, 1999 among the Company, the Subsidiary
Guarantors and First Union National Bank, as trustee (the "Trustee") and all
amendments thereto. We have also reviewed such matters of law and examined
original, certified, conformed or photographic copies of such other documents,
records, agreements and certificates as we have deemed necessary as a basis for
the opinions hereinafter expressed. In such review, we have assumed the
genuineness of signatures on all documents submitted to us as originals and the
conformity to original documents of all copies submitted to us as certified,
conformed or photographic copies, and, as to certificates of public officials,
we have assumed the same to have been properly given and to be accurate. As to
matters of fact material to this opinion, we have relied, without independent
investigation, upon statements and representations of representatives of the
Registrants, the Trustee and of public officials.

Delaware and New York, and no opinion is expressed with respect to the laws of
any other jurisdiction or any effect which such laws may have on the opinions
expressed herein. This opinion is limited to the matters stated herein, and no
opinion is implied or may be inferred beyond the matters expressly stated
herein.

     Based upon the foregoing, and subject to all of the assumptions,
limitations and qualifications set forth herein, we are of the opinion that:

     (a)  The issuance, execution and delivery of the New Notes have been duly
authorized by the Company, and when executed, authenticated, issued and
delivered in the manner provided for the Indenture in exchange for the Old
Notes, will constitute legal, valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms, subject, as to
enforcement of remedies, to bankruptcy, insolvency, reorganization, moratorium
or similar laws affecting creditors' rights generally and general equitable
principles. The New Notes will be entitled to the benefits of the Indenture.

     (b)  The Indenture constitutes a legal, valid and binding obligation of the
Company and each Subsidiary Guarantor, enforceable against the Company and each
Subsidiary Guarantor in accordance with their terms, subject, as to enforcement
of remedies, to bankruptcy, insolvency, reorganization, moratorium or similar
laws affecting creditors' rights generally and general equitable principles.


     (c)  The Guarantees constitute legal, valid and binding obligations of
each such Subsidiary Guarantor, enforceable against each Subsidiary Guarantor
in accordance with their terms, subject, as to enforcement of remedies, to
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
creditors' rights generally and general equitable principles.


     This opinion is given as of the date hereof, and we assume no obligation to
advise you after the date hereof of facts or circumstances that come to our
attention or changes in law that occur, which could affect the opinions
contained herein. This opinion may not be furnished to or relied upon by any
person or entity for any purpose without our prior written consent.

     We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the reference to us under the captions "Legal
Matters" in the Prospectus that is included in the Registration Statement.


                                            Very truly yours,

                  million incurred pursuant to the Term Loan Credit Agreement;

         1.5      Section 8.10 of the Credit Agreement is amended to read as
         follows:

                           Except with respect to (i) prohibitions against other
                  encumbrances on specific Property encumbered to secure payment
                  of particular Indebtedness (which Indebtedness relates solely
                  to such specific Property, and improvements and accretions
                  thereto, and is otherwise permitted hereby), (ii) the Term
                  Loan Credit Agreement and (iii) the Senior Subordinated Notes,
                  enter into, assume or become subject to any agreement
                  prohibiting or otherwise restricting the creation or
                  assumption of any Lien upon its properties or assets, whether
                  now owned or hereafter acquired, or requiring the grant of any
                  security for such obligation if security is given for some
                  other obligation.

         1.5      Clause (k) of Section 9.1 is renumbered as clause (l), and a
new clause (k) is added to read as follows:

                           (j) The occurrence of an Event of Default under the
                  Term Loan Credit Agreement;

<PAGE>   3

         2.       The Required Lenders hereby consent to the designation in the
Term Loan Credit Agreement that the Indebtedness evidenced thereby shall
constitute "Designated Senior Debt" (as such term is defined in the Senior
Subordinated Notes)).

         3.       By execution of this Amendment, the Required Lenders authorize
and direct the Administrative Agent, on behalf of the Lenders, to enter into the
Intercreditor Agreement.

         4.       This Amendment shall be effective as of the date hereof upon
execution of this Amendment by the Credit Parties and the Required Lenders.

         5.       The Credit Parties hereby affirm (i) the representations and
warranties set out in Section 6 of the Credit Agreement are true and correct as
of the date hereof (except those which expressly relate to an earlier period)
and (ii) no Default or Event of Default presently exists.

         6.       Each of the Guarantors (i) acknowledges and consents to all of
the terms and conditions of this Amendment, (ii) affirms all of its obligations
under the Credit Documents and (iii) agrees that this Amendment and all
documents executed in connection herewith do not operate to reduce or discharge
the Guarantors' obligations under the Credit Agreement or the other Credit
Documents.

         7.       The Borrower and the Guarantors, as applicable, affirm the
liens and security interests created and granted in the Credit Agreement and the
Credit Documents and agree that this Amendment shall in no manner adversely
affect or impair such liens and security interests.

         8.       Except as modified hereby, all of the terms and provisions of
the Credit Agreement (including Schedules and Exhibits) shall remain in full
force and effect.

         9.       The Borrower agrees to pay all reasonable costs and expenses
of the Administrative Agent in connection with the preparation, execution and
delivery of this Amendment, including without limitation the reasonable fees and
expenses of Moore & Van Allen, PLLC.

         10.      This Amendment may be executed in any number of counterparts,
each of which when so executed and delivered shall be deemed an original and it
shall not be necessary in making proof of this Amendment to produce or account
for more than one such counterpart.

         11.      This Amendment shall be deemed to be a contract made under,
and for all purposes shall be construed in accordance with the laws of the State
of New York.

         NOW, THEREFORE, IN CONSIDERATION of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

                                    SECTION 1
                                   DEFINITIONS

this Credit Agreement shall have the meanings assigned to such terms in the
Revolving Credit Agreement. As used in this Credit Agreement (including the
Incorporated Representations, the Incorporated Covenants and any definitions
incorporated herein from the Revolving Credit Agreement pursuant to the
foregoing sentence), the following terms shall have the meanings specified below

                  "Administrative Agent" shall have the meaning assigned to such

         Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on the
Loans and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable on demand, at a per annum rate 2% greater than the
rate which would otherwise be applicable (or if no rate is applicable, whether
in respect of interest, fees or other amounts, then 2% greater than the Base
Rate).

         3.2      Extension and Conversion.

         Subject to the terms of Section 5.2, the Borrower shall have the
option, on any Business Day, to extend existing Eurodollar Loans into a
subsequent permissible Interest Period or to convert Base Rate Loans into
Eurodollar Loans; provided, however, that (i) except as provided in Section 3.8,
Eurodollar Loans may be converted into Base Rate Loans only on the last day of
the Interest Period applicable thereto, (ii) Eurodollar Loans may be extended,
and Base Rate Loans may be converted into Eurodollar Loans, only if no Default
or Event of Default is in existence on the date of extension or conversion,
(iii) Loans extended as, or converted into, Eurodollar Loans shall be subject to
the terms of the definition of "Interest Period" and shall be in such minimum
amounts as provided in Section 2.1(c), and (iv) any request for extension or
conversion of a Eurodollar Loan which shall fail to specify an Interest Period
shall be deemed to be a request for an Interest Period of one month. Each such
extension or conversion shall be effected by the Borrower by giving a Notice of
Extension/Conversion (or telephone notice promptly confirmed in writing) to the
Administrative Agent prior to 11:00 A.M. (Charlotte, North Carolina time) on the
Business Day of, in the case of the conversion of a Eurodollar Loan into a Base
Rate Loan, and on the third Business Day prior to, in the case of the extension
of a Eurodollar Loan as, or conversion of a Base Rate


                                       9
<PAGE>   14
Loan into, a Eurodollar Loan, the date of the proposed extension or conversion,
specifying the date of the proposed extension or conversion, the Loans to be so
extended or converted, the types of Loans into which such Loans are to be
converted and, if appropriate, the applicable Interest Periods with respect
thereto. Each request for extension of a Eurodollar Loan or conversion of a
Base Rate Loan into a Eurodollar Loan shall be irrevocable and shall constitute
a representation and warranty by the Borrower of the matters specified in
subsections (a) and (b) of Section 5.2. In the event the Borrower fails to
request extension or conversion of any Eurodollar Loan in accordance with this
Section, or any such conversion or extension is not permitted or required by
this Section, then such Eurodollar Loan shall be automatically converted into a
Base Rate Loan at the end of the Interest Period applicable thereto. The
Administrative Agent shall give each Lender notice as promptly as practicable
of any such proposed extension or conversion affecting any Loan.

         3.3      Prepayments.

         (a)      Voluntary Prepayments. Loans may be repaid in whole or in part
without premium or penalty; provided that (i) Eurodollar Loans may be prepaid
only upon three (3) Business Days' prior written notice to the Administrative
Agent and must be accompanied by payment of any amounts owing under Section
3.11, and (ii) partial prepayments shall be (A) in the case of Eurodollar Loans,
in a minimum aggregate principal amount of US$2,500,000 and integral multiples
of US$500,000 in excess thereof and (B) in the case of Base Rate Loans, in a
minimum aggregate principal amount of US$100,000 and integral multiples of
US$50,000 in excess thereof.

         (b)      Mandatory Prepayments. If at any time the aggregate principal
Dollar Amount of Obligations plus the aggregate principal amount of the Term
Loan shall exceed the Borrowing Base, the Borrower shall immediately make
payment on the Term Loan and/or on the loans and other extensions of credit
outstanding under the Revolving Credit Agreement in an amount sufficient to
eliminate the excess.

         (c)      Application. Unless otherwise specified by the Borrower,
amounts prepaid on the Term Loan shall be applied first to Base Rate Loans, then
to Eurodollar Loans in direct order of Interest Period maturities. Amounts
prepaid on the Term Loan shall serve to reduce remaining principal installment
payments ratably and may not be reborrowed.

         3.4      [Intentionally Omitted].

         3.5      Fees.

         The Borrower agrees to pay to the Administrative Agent, for its own
account, the annual administrative fee and such other fees, if any, referred to
in the Administrative Agent's Fee Letter (collectively, the "Administrative
Agent's Fees").

         3.6      Capital Adequacy.

         If any Lender has reasonably determined, after the date hereof, that
the adoption or the becoming effective of, or any change in, or any change by
any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof in the interpretation or administration
of, any applicable law, rule or regulation regarding capital adequacy, or
compliance by such Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Lender's capital or assets as a consequence of its commitments or
obligations hereunder to a level below that which such Lender could have
achieved but for such adoption, effectiveness, change or compliance (taking into
consideration such Lender's policies with respect to capital adequacy), then,
subject to the provisions of Section 3.12, the Borrower shall be obligated to
pay to such Lender such additional amount or amounts as will compensate such
Lender for such reduction.

         3.7      Inability To Determine Interest Rate.

         If prior to the first day of any Interest Period, the Administrative
Agent shall have determined (which determination shall be conclusive and binding
upon the Borrower) that, by reason of circumstances affecting the relevant
market, adequate and reasonable means do not exist for ascertaining the
Eurodollar Rate for such Interest Period, the Administrative Agent shall give
telecopy or telephonic notice thereof to the Borrower and the Lenders as soon as
practicable thereafter (which notice shall be withdrawn the Administrative Agent
whenever such circumstances no longer exist). If such notice is given (a) any
Eurodollar Loans requested to be made on the first day of such Interest Period
shall be made as Base Rate Loans and (b) any Loans that were to have been
converted on the first day of such Interest Period to or continued as Eurodollar
Loans shall be converted to or continued as Base Rate Loans. Until such notice
has been withdrawn by the Administrative Agent, no further Eurodollar Loans
shall be made or continued as such, nor shall the Borrower have the right to
convert Base Rate Loans to Eurodollar Loans.

         3.8      Illegality.

         Notwithstanding any other provision herein, if the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
occurring after the Closing Date shall make it unlawful for any Lender to make
or maintain Eurodollar Loans as contemplated by this Credit Agreement, (a) such
Lender shall promptly give written notice of such circumstances to the Borrower
and the Administrative Agent (which notice shall be withdrawn by such Lender
whenever such circumstances no longer exist), (b) the commitment of such Lender
hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert a Base Rate Loan to Eurodollar Loans shall forthwith be canceled and,
until such time as it shall no longer be unlawful for such Lender to make or
maintain Eurodollar Loans, such Lender shall then have a commitment only to make
a Base Rate Loan when a Eurodollar Loan is requested and (c) such Lender's Loans
then outstanding as Eurodollar Loans, if any, shall be converted automatically
to Base Rate Loans on the respective last days of the then current Interest
Periods with respect to such Loans or within such earlier period as required by
law. If any such conversion of a Eurodollar Loan occurs on a day


                                       11
<PAGE>   16
which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to Section 3.11.

         3.9      Requirements of Law.

         If, after the date hereof, the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof applicable to
any Lender, or compliance by any Lender with any request or directive (whether
or not having the force of law) from any central bank or other Governmental
Authority, in each case made subsequent to the Closing Date (or, if later, the
date on which such Lender becomes a Lender):

         (a)      shall subject such Lender to any tax of any kind whatsoever
with respect to any Eurodollar Loans made by it or its obligation to make
Eurodollar Loans, or change the basis of taxation of payments to such Lender in
respect thereof (except for (i) Taxes covered by Section 3.10 (including Taxes
imposed solely by reason of any failure of such Lender to comply with its
obligations under Section 3.10(d)) and (ii) changes in taxes measured by or
imposed upon the overall net income, or franchise tax (imposed in lieu of such
net income tax), of such Lender or its applicable lending office, branch, or any
affiliate thereof));

         (b)      shall impose, modify or hold applicable any reserve, special
deposit, compulsory loan or similar requirement against assets held by, deposits
or other liabilities in or for the account of, advances, loans or other
extensions of credit by, or any other acquisition of funds by, any office of
such Lender which is not otherwise included in the determination of the
Eurodollar Rate hereunder; or

         (c)      shall impose on such Lender any other condition (excluding any
tax of any kind whatsoever);

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, subject to the provisions
of Section 3.12, the Borrower shall be obligated to promptly pay such Lender,
upon its demand, any additional amounts necessary to compensate such Lender for
such increased cost or reduced amount receivable, provided that, in any such
case, the Borrower may elect to convert the Eurodollar Loans made by such Lender
hereunder to Base Rate Loans by giving the Administrative Agent at least one
Business Day's notice of such election, in which case the Borrower shall
promptly pay to such Lender, upon demand, without duplication, such amounts, if
any, as may be required pursuant to Section 3.11. Each Lender agrees that, as
promptly as practicable after it becomes aware of any circumstances of the type
referred to in paragraphs (a) through (c) above which would result in any such
increased cost or reduced amount receivable, the affected Lender shall, to the
extent not inconsistent with such Lender's internal policies of general
application, designate a different lending office for the making of Loans
hereunder or otherwise use reasonable commercial efforts to minimize the amounts
payable to it by the Borrower pursuant to this Section 3.9. This covenant shall
survive the termination of this Credit Agreement and the payment of the Loans
and all other amounts payable hereunder.

         3.10     Taxes.

         (a)      Any and all payments by any Credit Party to or for the account
of any Lender or the Administrative Agent hereunder or under any other Credit
Document shall be made free and clear of and without deduction for any and all
present or future taxes, duties, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, in the case
of each Lender and the Administrative Agent, taxes imposed on its income, and
franchise taxes imposed on it, by the jurisdiction under the laws of which such
Lender (or its applicable lending office) or the Administrative Agent (as the
case may be) is organized or any political subdivision thereof (all such
non-excluded taxes, duties, levies, imposts, deductions, charges, withholdings,
and liabilities being hereinafter referred to as "Taxes"). If any Credit Party
shall be required by law to deduct or withhold any Taxes from or in respect of
any sum payable under this Credit Agreement or any other Credit Document to any
Lender or the Administrative Agent, (i) the sum payable shall be increased as
necessary so that after making all required deductions and withholdings
(including deductions and withholdings applicable to additional sums payable
under this Section 3.10) such Lender or the Administrative Agent receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) such Credit Party shall make such deductions and withholdings, (iii) such
Credit Party shall pay the full amount deducted or withheld to the relevant
taxation authority or other authority in accordance with applicable law, and
(iv) such Credit Party shall furnish to the Administrative Agent, in each case
at its address referred to in Section 9.1, the original or a certified copy of a
receipt evidencing payment thereof.

         (b)      In addition, the Borrower agrees to pay any and all present or
future stamp or documentary taxes and any other excise or property taxes or
charges or similar levies which arise from any payment made under this Credit
Agreement or any other Credit Document or from the execution or delivery of, or
otherwise with respect to, this Credit Agreement or any other Credit Document
(hereinafter referred to as "Other Taxes").

         (c)      The Borrower agrees to indemnify each Lender and the
Administrative Agent for the full amount of Taxes and Other Taxes (including,
without limitation, any Taxes or Other Taxes imposed or asserted by any
jurisdiction on amounts payable under this Section 3.10) paid by such Lender or
the Administrative Agent (as the case may be) and any liability (including
penalties, interest, and expenses) arising therefrom or with respect thereto.

         (d)      Each Lender that is not a United States person under Section
7701(a)(30) of the Internal Revenue Code, on or prior to the date of its
execution and delivery of this Credit Agreement in the case of each Lender
listed on the signature pages hereto and on or prior to the date on which it
becomes a Lender in the case of each other Lender, and from time to time
thereafter if requested in writing by the Borrowers or the Administrative Agent
(but only so long as such Lender remains lawfully able to do so), shall provide
the Borrower and the Administrative Agent with (i) Internal Revenue Service Form
W-8 BEN or W-8 ECI, as appropriate, or any successor form prescribed by the
Internal Revenue Service, certifying that such Lender is entitled to benefits
under an income tax treaty to which the United States is a party which reduces
to zero the rate of withholding tax on payments of interest or certifying that




                                       13
<PAGE>   18

the income receivable pursuant to this Credit Agreement is effectively connected
with the conduct of a trade or business in the United States, (ii) Internal
Revenue Service Form W-8 or W-9, as appropriate, or any successor form
prescribed by the Internal Revenue Service, and/or (iii) any other form or
certificate required by any taxing authority (including any certificate required
by Sections 871(h) and 881(c) of the Internal Revenue Code), certifying that
such Lender is entitled to an exemption from tax on payments pursuant to this
Credit Agreement or any of the other Credit Documents.

         (e)      For any period with respect to which a Lender has failed to
provide the Borrower and the Administrative Agent with the appropriate form
pursuant to Section 3.10(d) (unless such failure is due to a change in treaty,
law, or regulation occurring subsequent to the date on which a form originally
was required to be provided), such Lender shall not be entitled to
indemnification under Section 3.10(a) or 3.10(b) with respect to Taxes imposed
by the United States; provided, however, that should a Lender, which is
otherwise exempt from or subject to a reduced rate of withholding tax, become
subject to Taxes because of its failure to deliver a form required hereunder,
the Borrower shall take such steps as such Lender shall reasonably request to
assist such Lender to recover such Taxes.

         (f)      If any Credit Party is required to pay additional amounts to
or for the account of any Lender pursuant to this Section 3.10, then such Lender
will agree to use reasonable efforts to change the jurisdiction of its
applicable lending office so as to eliminate or reduce any such additional
payment which may thereafter accrue if such change, in the judgment of such
Lender, is not otherwise disadvantageous to such Lender.

         (g)      Within thirty (30) days after the date of any payment of
Taxes, the applicable Credit Party shall furnish to the Administrative Agents
the original or a certified copy of a receipt evidencing such payment.

         (h)      Without prejudice to the survival of any other agreement of
the Credit Parties hereunder, the agreements and obligations of the Credit
Parties contained in this Section 3.10 shall survive the repayment of the Loans
and other obligations under the Credit Documents and the termination of the
Commitments hereunder.

         3.11     Indemnity.

         The Borrower promises to indemnify each Lender and to hold each Lender
harmless from any loss or expense which such Lender may sustain or incur (other
than through such Lender's gross negligence or willful misconduct) as a
consequence of (a) default by the Borrower in making a borrowing of, conversion
into or continuation of Eurodollar Loans after the Borrower has given a notice
requesting the same in accordance with the provisions of this Credit Agreement,
(b) default by the Borrower in making any prepayment of a Eurodollar Loan after
the Borrower has given a notice thereof in accordance with the provisions of
this Credit Agreement or (c) the making of a prepayment of Eurodollar Loans on a
day which is not the last day of an Interest Period with respect thereto. With
respect to Eurodollar Loans, such indemnification may be calculated, in lieu of
any other method, based on an amount equal to the excess, if any, of (i) the
amount of interest




                                       14
<PAGE>   19

which would have accrued on the amount so prepaid, or not so borrowed, converted
or continued, for the period from the date of such prepayment or of such failure
to borrow, convert or continue to the last day of the applicable Interest Period
(or, in the case of a failure to borrow, convert or continue, the Interest
Period that would have commenced on the date of such failure) in each case at
the applicable rate of interest for such Loans provided for herein over (ii) the
amount of interest (as reasonably determined by such Lender) which would have
accrued to such Lender on such amount by placing such amount on deposit for a
comparable period with leading banks in the interbank Eurodollar market. The
covenants of the Borrower set forth in this Section 3.11 shall survive the
termination of this Credit Agreement and the payment of the Loans and all other
amounts payable hereunder.

         3.12     Certain Limitations.

         The provisions of Sections 3.6, 3.9, 3.10 and 3.11 hereof shall be
subject to the following:

         (a)      Each Lender that desires compensation or indemnification under
Sections 3.6, 3.9 or 3.11 hereof shall notify the Borrower through the
Administrative Agent of any event occurring after the Closing Date entitling
such Lender to compensation or indemnification under any of such Sections as
promptly as practicable, but in any event within 90 days after the occurrence of
the event giving rise thereto; provided that (i) if any such Lender fails to
give such notice within 90 days after the occurrence of such an event, such
Lender shall only be entitled to compensation or indemnification in respect of
such event accruing under Sections 3.6, 3.9 or 3.11 hereof with respect to the
period from and after the date 90 days prior to the date that such Lender does
give notice.

         (b)      Any notice given by a Lender pursuant to subsection (a) above
shall certify (i) that one of the events described in Sections 3.6, 3.9 or 3.11
hereof has occurred, describing in reasonable detail the nature of such event,
(ii) as to the increased cost, reduced amount receivable or loss or expense
resulting from such event and (iii) as to the additional amount demanded by such
Lender, attaching a reasonably detailed explanation of the calculation thereof.
Such a certificate as to any compensation or indemnification payable pursuant to
Sections 3.6, 3.9 or 3.11, submitted by such Lender through the Administrative
Agent to the Borrower, shall be conclusive and binding on the parties hereto in
the absence of manifest error.

         (c)      If any Lender requests compensation or indemnification from
the Borrower under Sections 3.6, 3.9 or 3.10 hereof, the Borrower may, at its
option, within fifteen (15) days after receipt by the Borrower of written demand
from the affected Lender for payment of such compensation or indemnification,
notify the Administrative Agent and such affected Lender of its intention to
replace the affected Lender. So long as no Event of Default shall have occurred
and be continuing, the Borrower may obtain, at the Borrower's expense, a
replacement Lender for the affected Lender. If the Borrower obtains a
replacement Lender within ninety (90) days following notice of its intention to
do so, the affected Lender must sell and assign its Loans and any related
Commitments to such replacement Lender pursuant to Section 9.3(b) hereof
(without giving effect to any requirement therein that the Administrative Agent
consent thereto), for an amount equal to the principal balance of all Loans held
by the affected Lender and all accrued



                                       15
<PAGE>   20
interest and Fees with respect thereto through the date of such sale, provided
that the Borrower shall have paid to such affected Lender the compensation or
indemnification that it is entitled to receive under Sections 3.6, 3.9 or 3.10
hereof, through the date of such sale and assignment. Notwithstanding the
foregoing, the Borrower shall not have the right to obtain a replacement Lender
if the affected Lender rescinds its demand for such compensation or
indemnification within fifteen (15) days following its receipt of the Borrower's
notice of intention to replace such affected Lender. Additionally, if the
Borrower gives a notice to the Administrative Agent and an affected Lender of
its intention to replace such affected Lender and does not so replace such
affected Lender within ninety (90) days thereafter, the Borrower's rights under
this Section 3.12(c) shall terminate and the Borrower shall promptly pay all
compensation or indemnification demanded by such affected Lender pursuant to
Sections 3.6, 3.9 or 3.10 hereof.

         3.13     Pro Rata Treatment.

         Except to the extent otherwise provided herein:

         (a)      Loans. Each payment or prepayment of principal on the Term
Loan, each payment of interest on the Term Loan and each conversion or extension
of any Loan comprising the Term Loan, shall be allocated pro rata among the
Lenders in accordance with the respective principal amounts of their respective
Term Loan Commitment Percentages.

         (b)      Advances. No Lender shall be responsible for the failure or
delay by any other Lender in its obligation to make its ratable share of a
borrowing hereunder; provided, however, that the failure of any Lender to
fulfill its obligations hereunder shall not relieve any other Lender of its
obligations hereunder. Unless the Administrative Agent shall have been notified
in writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its ratable share of such borrowing available to
the Administrative Agent, the Administrative Agent may assume that such Lender
is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such amount is not made available to the
Administrative Agent by such Lender within the time period specified therefor
hereunder, such Lender shall pay to the Administrative Agent, on demand, such
amount with interest thereon at a rate equal to the Federal Funds Rate for a
period of two (2) Business Days, and thereafter at the Base Rate, for the period
until such Lender makes such amount immediately available to the Administrative
Agent. If such Lender does not pay such amounts to the Administrative Agent
forthwith upon demand, the Administrative Agent may notify the Borrower and
request the Borrower to immediately pay such amount to the Administrative Agent
with interest at the rate applicable thereto. A certificate of the
Administrative Agent submitted to any Lender with respect to any amounts owing
under this subsection shall be conclusive in the absence of manifest error.

         3.14     Sharing of Payments.

         The Lenders agree among themselves that, in the event that any Lender
shall obtain payment in respect of any Loan or any other obligation owing to
such Lender under this Credit Agreement through the exercise of a right of
setoff, banker's lien or counterclaim, or pursuant to a



                                       16
<PAGE>   21
secured claim under Section 506 of the Bankruptcy Code or other security or
interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise, or by any other means, in excess of its pro rata share of such
payment as provided for in this Credit Agreement, such Lender shall promptly
purchase from the other Lenders a participation in such Loans and other
obligations in such amounts, and make such other adjustments from time to time,
as shall be equitable to the end that all Lenders share such payment in
accordance with their respective ratable shares as provided for in this Credit
Agreement. The Lenders further agree among themselves that if payment to a
Lender obtained by such Lender through the exercise of a right of setoff,
banker's lien, counterclaim or other event as aforesaid shall be rescinded or
must otherwise be restored, each Lender which shall have shared the benefit of
such payment shall, by repurchase of a participation theretofore sold, return
its share of that benefit (together with its share of any accrued interest
payable with respect thereto) to each Lender whose payment shall have been
rescinded or otherwise restored. The Borrower agrees that any Lender so
purchasing such a participation may, to the fullest extent permitted by law,
exercise all rights of payment, including setoff, banker's lien or counterclaim,
with respect to such participation as fully as if such Lender were a holder of
such Loan or other obligation in the amount of such participation. Except as
otherwise expressly provided in this Credit Agreement, if any Lender or either
Agent shall fail to remit to an Agent or any other Lender an amount payable by
such Lender or such Agent to such Agent or such other Lender pursuant to this
Credit Agreement on the date when such amount is due, such payments shall be
made together with interest thereon for each date from the date such amount is
due until the date such amount is paid to such Agent or such other Lender at a
rate per annum equal to the Federal Funds Rate. If under any applicable
bankruptcy, insolvency or other similar law, any Lender receives a secured claim
in lieu of a setoff to which this Section 3.14 applies, such Lender shall, to
the extent practicable, exercise its rights in respect of such secured claim in
a manner consistent with the rights of the Lenders under this Section 3.14 to
share in the benefits of any recovery on such secured claim.

         3.15     Payments, Computations, Etc.

         (a)      Except as otherwise specifically provided herein, all payments
hereunder shall be made to the Administrative Agent in U.S. Dollars in
immediately available funds, without setoff, deduction, counterclaim or
withholding of any kind, at the Administrative Agent's office specified in
Section 9.1 not later than 2:00 P.M. (Charlotte, North Carolina time) on the
date when due. Payments received after such time shall be deemed to have been
received on the next succeeding Business Day. The Administrative Agent may (but
shall not be obligated to) debit the amount of any such payment which is not
made by such time to any ordinary deposit account of the Borrower maintained
with the Administrative Agent (with notice to the Borrower). The Borrower shall,
at the time it makes any payment under this Credit Agreement, specify to the
Administrative Agent the Loans, Fees, interest or other amounts payable by the
Borrower hereunder to which such payment is to be applied (and in the event that
it fails so to specify, or if such application would be inconsistent with the
terms hereof, the Administrative Agent shall distribute such payment to the
Lenders in such manner as the Administrative Agent may determine to be
appropriate in respect of obligations owing by the Borrower hereunder, subject
to the terms of Section 3.13(a)). The Administrative Agent will distribute such
payments to such Lenders, if any such payment is received prior to 12:00 Noon
(Charlotte, North Carolina time) on a Business Day in like funds as




                                       17
<PAGE>   22
received prior to the end of such Business Day and otherwise the Administrative
Agent will distribute such payment to such Lenders entitled thereto on the next
succeeding Business Day. Whenever any payment hereunder shall be stated to be
due on a day which is not a Business Day, the due date thereof shall be extended
to the next succeeding Business Day (subject to accrual of interest and Fees for
the period of such extension), except that in the case of Eurodollar Loans, if
the extension would cause the payment to be made in the next following calendar
month, then such payment shall instead be made on the next preceding Business
Day. Except as expressly provided otherwise herein, all computations of interest
and fees shall be made on the basis of the actual number of days elapsed over a
year of 360 days, except with respect to computation of interest on Base Rate
Loans which (unless the Base Rate is determined by reference to the Federal
Funds Rate) shall be calculated based on a year of 365 or 366 days, as
appropriate. Interest shall accrue from and include the date of borrowing, but
exclude the date of payment.

         (b)      Allocation of Payments After Event of Default. Notwithstanding
any other provisions of this Credit Agreement to the contrary, after the
occurrence and during the continuance of an Event of Default, all amounts

         and expenses (including without limitation reasonable attorneys' fees)
         of the Agents in connection with enforcing the rights of the Lenders

                  SECOND, to payment of any Administrative Agent's Fees then

         Term Loan owing to such Lender;

                  FOURTH, to the payment of all accrued interest and Fees on or

         In carrying out the foregoing, (i) amounts received shall be applied in
         the numerical order provided until exhausted prior to application to
         the next succeeding category; and (ii) each of the Lenders shall
         receive an amount equal to its pro rata share (based on the proportion




                                       18
<PAGE>   23

         that the then outstanding Term Loan held by such Lender bears to the
         aggregate then outstanding Term Loan) of amounts available to be
         applied pursuant to clauses "THIRD", "FOURTH", "FIFTH" and "SIXTH"
         above.

         3.16     Evidence of Debt.

         (a)      Each Lender shall maintain an account or accounts evidencing
each Loan made by such Lender to the Borrower from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Credit Agreement. Each Lender will make reasonable efforts to
maintain the accuracy of its account or accounts and to promptly update its
account or accounts from time to time, as necessary.

         (b)      The Administrative Agent shall maintain the Register pursuant
to Section 9.3(c) hereof, and a subaccount for each Lender, in which Register
and subaccounts (taken together) shall be recorded (i) the amount, type and
Interest Period of each such Loan hereunder, (ii) the amount of any principal or
interest due and payable or to become due and payable to each Lender hereunder
and (iii) the amount of any sum received by the Administrative Agent hereunder

         (c)      The entries made in the accounts, Register and subaccounts
maintained pursuant to subsection (b) of this Section 3.16 (and, if consistent
with the entries of the Administrative Agent, subsection (a)) shall be prima
facie evidence of the existence and amounts of the obligations of the Borrower
therein recorded; provided, however, that the failure of any Lender or the
Administrative Agent to maintain any such account, such Register or such
subaccount, as applicable, or any error therein, shall not in any manner affect
the obligation of the Borrower to repay the Loans made by such Lender in
accordance with the terms hereof.


                                    SECTION 4
                                    GUARANTY

         4.1      The Guarantee.

         (a)      Each of the Guarantors hereby jointly and severally guarantees
to each Lender, to each Affiliate of a Lender that enters into a Hedging
Agreement to the extent permitted hereunder, and to the Agents as hereinafter
provided, the prompt payment of the Guaranteed Obligations in full when due
(whether at stated maturity, as a mandatory prepayment, by acceleration, as a
mandatory cash collateralization or otherwise) strictly in accordance with the
terms thereof. The Guarantors hereby further agree that if any of the Guaranteed
Obligations are not paid in full when due (whether at stated maturity, as a
mandatory prepayment, by acceleration, as a mandatory cash collateralization or
otherwise), the Guarantors will, jointly and severally, promptly pay the same,
without any demand or notice whatsoever, and that in the case of any extension
of time of payment or renewal of any of the Guaranteed Obligations, the same
will be promptly paid in full when due


                                       19
<PAGE>   24
(whether at extended maturity, as a mandatory prepayment, by acceleration, as a
mandatory cash collateralization or otherwise) in accordance with the terms of
such extension or renewal.

         (b) Notwithstanding any provision to the contrary contained herein or
in any other of the Credit Documents or Hedging Agreements, to the extent the
obligations of a Guarantor shall be adjudicated to be invalid or unenforceable
for any reason (including, without limitation, because of any applicable state
or federal law relating to fraudulent conveyances or transfers) then the
obligations of each Guarantor hereunder shall be limited to the maximum amount
that is permissible under applicable law (whether federal or state and
including, without limitation, the Bankruptcy Code).

         4.2      Obligations Unconditional.

         The obligations of the Guarantors under Section 4.1 hereof are joint
and several, absolute and unconditional, irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Credit Documents or Hedging
Agreements, or any other agreement or instrument referred to therein, or any
substitution, release or exchange of any other guarantee of or security for any
of the Guaranteed Obligations, and, to the fullest extent permitted by
applicable law, irrespective of any other circumstance whatsoever which might
otherwise constitute a legal or equitable discharge or defense of a surety or
guarantor, it being the intent of this Section 4.2 that the obligations of the
Guarantors hereunder shall be absolute and unconditional under any and all
circumstances. Each Guarantor agrees that such Guarantor shall have no right of
subrogation, indemnity, reimbursement or contribution against the Borrower or
any other Guarantor of the Guaranteed Obligations for amounts paid under this
Guaranty until such time as the Lenders (and any Affiliates of Lenders entering
into Hedging Agreements) have been paid in full, all Commitments under the
Credit Agreement have been terminated and no Person or Governmental Authority
shall have any right to request any return or reimbursement of funds from the
Lenders in connection with monies received under the Credit Documents or Hedging
Agreements. Without limiting the generality of the foregoing, it is agreed that,
to the fullest extent permitted by law, the occurrence of any one or more of the
following shall not alter or impair the liability of any Guarantor hereunder
which shall remain absolute and unconditional as described above:

                  (i)      at any time or from time to time, without notice to
         any Guarantor, the time for any performance of or compliance with any
         of the Guaranteed Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (ii)     any of the acts mentioned in any of the provisions of
         any of the Credit Documents, any Hedging Agreement or any other
         agreement or instrument referred to in the Credit Documents or Hedging
         Agreements shall be done or omitted;

                  (iii)    the maturity of any of the Guaranteed Obligations
         shall be accelerated, or any of the Guaranteed Obligations shall be
         modified, supplemented or amended in any respect, or any right under
         any of the Credit Documents, any Hedging Agreement or any other
         agreement or instrument referred to in the Credit Documents or Hedging
         Agreements shall


                                       20
<PAGE>   25

         be waived or any other guarantee of any of the Guaranteed Obligations
         or any security therefor shall be released or exchanged in whole or in
         part or otherwise dealt with;

                  (iv)     any Lien granted to, or in favor of, either Agent or
         any Lender or Lenders as security for any of the Guaranteed Obligations
         shall fail to attach or be perfected; or

                  (v)      any of the Guaranteed Obligations shall be determined
         to be void or voidable (including, without limitation, for the benefit
         of any creditor of any Guarantor) or shall be subordinated to the
         claims of any Person (including, without limitation, any creditor of
         any Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that either Agent or any Lender exhaust any
right, power or remedy or proceed against any Person under any of the Credit
Documents, any Hedging Agreement or any other agreement or instrument referred
to in the Credit Documents or Hedging Agreements, or against any other Person
under any other guarantee of, or security for, any of the Guaranteed
Obligations.

         4.3      Reinstatement.

         The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Guaranteed Obligations is rescinded
or must be otherwise restored by any holder of any of the Guaranteed
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
each Agent and each Lender on demand for all reasonable costs and expenses
(including, without limitation, reasonable fees and expenses of counsel)
incurred by such Agent or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

         4.4      Certain Additional Waivers.

         Each Guarantor agrees that such Guarantor shall have no right of
recourse to security for the Guaranteed Obligations, except through the exercise
of the rights of subrogation pursuant to Section 4.2.

         4.5      Remedies.

         The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Agents and the Lenders, on the
other hand, the Guaranteed Obligations may be declared to be forthwith due and
payable as provided in Section 7.2 hereof (and shall be deemed to have become
automatically due and payable in the circumstances provided in said Section 7.2)
for purposes of Section 4.1 hereof notwithstanding any stay, injunction or other
prohibition preventing such declaration (or preventing the Guaranteed
Obligations from becoming




                                       21
<PAGE>   26

automatically due and payable) as against any other Person and that, in the
event of such declaration (or the Guaranteed Obligations being deemed to have
become automatically due and payable), the Guaranteed Obligations (whether or
not due and payable by any other Person) shall forthwith become due and payable
by the Guarantors for purposes of said Section 4.1.

         4.6      Rights of Contribution.

         The Guarantors hereby agree, as among themselves, that if any Guarantor
shall become an Excess Funding Guarantor (as defined below), each other
Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the
succeeding provisions of this Section 4.6), pay to such Excess Funding Guarantor
an amount equal to such Guarantor's Pro Rata Share (as defined below and
determined, for this purpose, without reference to the properties, assets,
liabilities and debts of such Excess Funding Guarantor) of such Excess Payment
(as defined below). The payment obligation of any Guarantor to any Excess
Funding Guarantor under this Section 4.6 shall be subordinate and subject in
right of payment to the prior payment in full of the obligations of such
Guarantor under the other provisions of this Section 4, and such Excess Funding
Guarantor shall not exercise any right or remedy with respect to such excess
until payment and satisfaction in full of all of such obligations. For purposes
hereof, (i) "Excess Funding Guarantor" shall mean, in respect of any obligations
arising under the other provisions of this Section 4 (hereafter, the "Guarantied
Obligations"), a Guarantor that has paid an amount in excess of its Pro Rata
Share of the Guarantied Obligations; (ii) "Excess Payment" shall mean, in
respect of any Guarantied Obligations, the amount paid by an Excess Funding
Guarantor in excess of its Pro Rata Share of such Guarantied Obligations; and
(iii) "Pro Rata Share", for the purposes of this Section 4.6, shall mean, for
any Guarantor, the ratio (expressed as a percentage) of (a) the amount by which
the aggregate present fair saleable value of all of its assets and properties
exceeds the amount of all debts and liabilities of such Guarantor (including
contingent, subordinated, unmatured, and unliquidated liabilities, but excluding
the obligations of such Guarantor hereunder) to (b) the amount by which the
aggregate present fair saleable value of all assets and other properties of the
Borrower and all of the Guarantors exceeds the amount of all of the debts and
liabilities (including contingent, subordinated, unmatured, and unliquidated
liabilities, but excluding the obligations of the Borrower and the Guarantors
hereunder) of the Borrower and all of the Guarantors, all as of the Closing Date
(if any Guarantor becomes a party hereto subsequent to the Closing Date, then
for the purposes of this Section 4.6 such subsequent Guarantor shall be deemed
to have been a Guarantor as of the Closing Date and the information pertaining
to, and only pertaining to, such Guarantor as of the date such Guarantor became
a Guarantor shall be deemed true as of the Closing Date).

         4.7      Continuing Guarantee.

         The guarantee in this Section 4 is a continuing guarantee, and shall
apply to all Guaranteed Obligations whenever arising.

Credit Agreement) and covenant and agree that the Incorporated Covenants shall
be as binding on the Credit Parties as if set forth fully herein, provided that

Revolving Credit Agreement), (ii) in the event of the amendment or modification
of any of the affirmative and negative covenants contained in Sections 6 and 7
of the Revolving Credit Agreement, the Incorporated Covenants shall be as in

expenditures and other general corporate purposes, including, without
limitation, acquisitions permitted hereunder.

Administrative Agent, for the benefit of the Lenders, a Joinder Agreement and
the other items required by Section 7.11 of the Incorporated Covenants in the
same form and from the same Domestic Subsidiaries as required therein, except

dissolution, merger or disposition permitted by Section 8.3 or Section 8.4 , in
each case of the Incorporated Covenants, any Credit Document shall fail to be in
full force and effect or to give the Administrative Agent and/or the Lenders any

whole, (A) (1) any Material Credit Party shall default in any payment (beyond
the applicable grace period with respect thereto, if any) with respect to any
such Indebtedness, or (2) the occurrence and continuance of a default in the
observance or performance relating to such Indebtedness or contained in any

and unpaid at such time, exceeds US$3,000,000, and which is not stayed on appeal
(or for which no motion for stay is pending) or is not otherwise being executed;
or

         (i)      ERISA. Any of the following events or conditions, if such
event or condition could reasonably be expected to have a Material Adverse
Effect: (1) any "accumulated funding deficiency," as such term is defined in

ERISA Affiliate incurring any liability in connection with a withdrawal from,
reorganization of (within the meaning of Section


                                       27

         7.2      Acceleration; Remedies.

         Upon the occurrence and during the continuation of an Event of Default,

actions without prejudice to the rights of either Agent or any Lender to enforce
its claims against the Credit Parties, except as expressly provided for herein:

                  (i)      Acceleration. Declare the unpaid principal of and any
         accrued interest in respect of all Loans and any and all other
         indebtedness or obligations of any and every kind owing by the Credit
         Parties to either Agent and/or any of the Lenders under the Credit
         Documents to be due whereupon the same shall be immediately due and
         payable without presentment, demand, protest or other notice of any

accrued and unpaid Fees and other indebtedness or obligations owing to either
Agent and/or any of the Lenders hereunder automatically shall immediately become
due and payable without presentment, demand, protest or the giving of any notice
or other action by the Agents or the Lenders, all of which are hereby waived by
the Credit Parties.

                                AGENCY PROVISIONS

         8.1      Appointment.

         Each Lender hereby designates and appoints Bank of America as

Agreement and the other Credit Documents and to exercise such powers and perform
such duties as are expressly delegated to the Agents by the terms hereof and of
the other Credit Documents, together with such other powers as are reasonably

responsibilities, duties, obligations or liabilities shall be read into this
Credit Agreement or any of the other Credit Documents, or shall otherwise exist
against either Agent. The provisions of this Section are solely for the benefit
of the Agents and the Lenders, and none of the Credit Parties shall have any

forth in the second sentence hereof). In performing their functions and duties
under this Credit Agreement and the other Credit Documents, the Agents shall act
solely as Agent of the Lenders and do not assume and shall not be deemed to have
assumed any obligation or relationship of agency or trust with or for any Credit
Party or any of their respective Affiliates.

         8.2      Delegation of Duties.

         The Agents may execute any of their duties hereunder or under the other

attorneys-in-fact or affiliates shall be (i) liable for any action lawfully
taken or omitted to be taken by it or such Person under or in connection
herewith or in connection with any of the other Credit Documents (except for its
or such Person's own gross negligence or willful misconduct), or (ii)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by any of the Credit Parties contained herein
or in any of the other Credit Documents or in any certificate, report, document,
financial statement or other written or oral statement referred to or provided
for in, or received by such Agent under or in connection herewith or in
connection with the other Credit


                                       29
<PAGE>   34
Documents, or enforceability or sufficiency therefor of any of the other Credit
Documents, or for any failure of any Credit Party to perform its obligations
hereunder or thereunder. No Agent shall be responsible to any Lender for the
effectiveness, genuineness, validity, enforceability, collectability or
sufficiency of this Credit Agreement, or any of the other Credit Documents or
for any representations, warranties, recitals or statements made herein or
therein or made by the Borrower or any Credit Party in any written or oral
statement or in any financial or other statements, instruments, reports,
certificates or any other documents in connection herewith or therewith
furnished or made by such Agent to the Lenders or by or on behalf of the Credit
Parties to such Agent or any Lender or be required to ascertain or inquire as to
the performance or observance of any of the terms, conditions, provisions,
covenants or agreements contained herein or therein or as to the use of the
proceeds of the Term Loan or of the existence or possible existence of any
Default or Event of Default or to inspect the properties, books or records of
the Credit Parties or any of their respective Affiliates.

         8.4      Reliance on Communications.

         Each Agent shall be entitled to rely, and shall be fully protected in
relying, upon any note, writing, resolution, notice, consent, certificate,
affidavit, letter, cablegram, telegram, telecopy, telex or teletype message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to any of the Credit Parties, independent accountants and
other experts selected by such Agent with reasonable care). Each Agent may deem
and treat the Lenders as the owners of their respective interests hereunder for
all purposes unless a written notice of assignment, negotiation or transfer
thereof shall have been filed with the Administrative Agent in accordance with
Section 9.3(b). Each Agent shall be fully justified in failing or refusing to
take any action under this Credit Agreement or under any of the other Credit
Documents unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action.
Each Agent shall in all cases be fully protected in acting, or in refraining
from acting, hereunder or under any of the other Credit Documents in accordance
with a request of the Required Lenders (or to the extent specifically provided
in Section 9.6, all the Lenders) and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders (including
their successors and assigns).

         8.5      Notice of Default.

         No Agent shall be deemed to have knowledge or notice of the occurrence
of any Default or Event of Default hereunder unless such Agent has received
notice from a Lender or a Credit Party referring to the Credit Document,
describing such Default or Event of Default and stating that such notice is a
"notice of default." In the event that such Agent receives such a notice, such
Agent shall give prompt notice thereof to the other Agent and the Lenders. The
Agents shall take such action with respect to such Default or Event of Default
as shall be reasonably directed by the Required Lenders.

<PAGE>   35

         8.6      Non-Reliance on Administrative Agent and Other Lenders.

         Each Lender expressly acknowledges that neither Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates has made
any representations or warranties to it and that no act by the Agents or any
affiliate thereof hereinafter taken, including any review of the affairs of any
Credit Party or any of their respective Affiliates, shall be deemed to
constitute any representation or warranty by any Agent to any Lender. Each
Lender represents to the Agents that it has, independently and without reliance
upon either Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, assets, operations, property, financial and
other conditions, prospects and creditworthiness of the Borrower, the other
Credit Parties or their respective Affiliates and made its own decision to make
its Loans hereunder and enter into this Credit Agreement. Each Lender also
represents that it will, independently and without reliance upon either Agent or
any other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Credit Agreement, and to
make such investigation as it deems necessary to inform itself as to the
business, assets, operations, property, financial and other conditions,
prospects and creditworthiness of the Borrower, the other Credit Parties and
their respective Affiliates. Except for notices, reports and other documents
expressly required to be furnished to the Lenders by the Administrative Agent
hereunder, the Agents shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, operations,
assets, property, financial or other conditions, prospects or creditworthiness
of the Borrower, the other Credit Parties or any of their respective Affiliates
which may come into the possession of either Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates.

         8.7      Indemnification.

         The Lenders agree to indemnify each Agent in its capacity as such (to
the extent not reimbursed by the Borrower and without limiting the obligation of
the Borrower to do so), ratably in accordance with the respective principal
amounts of outstanding Loans and Participation Interests of the Lenders), from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever which may at any time (including without limitation at any time
following the final payment of all of the obligations of the Borrower hereunder
and under the other Credit Documents) be imposed on, incurred by or asserted
against such Agent in its capacity as such in any way relating to or arising out
of this Credit Agreement or the other Credit Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by such Agent
under or in connection with any of the foregoing; provided that no Lender shall
be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the gross negligence or willful misconduct of such
Agent. If any indemnity furnished to an Agent for any purpose shall, in the
opinion of such Agent, be insufficient or become impaired, such Agent may call
for additional indemnity and cease, or not commence, to do the acts indemnified
against until such additional indemnity is furnished. The agreements in this
Section shall survive the repayment


                                       31
<PAGE>   36

of the Loans and other obligations under the Credit Documents and the
termination of the Commitments hereunder.

         8.8      Administrative Agent in its Individual Capacity.

         The Agents and their affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Borrower, its Subsidiaries
or their respective Affiliates as though the Agents were not the Agents
hereunder. With respect to the Loans made by and all obligations of the Borrower
hereunder and under the other Credit Documents, the Agents shall have the same
rights and powers under this Credit Agreement as any Lender and may exercise the
same as though it were not an Agent, and the terms "Lender" and "Lenders" shall
include the Agents in its individual capacity.

         8.9      Successor Administrative Agent.

         Any Agent may, at any time, resign upon 20 days' written notice to the
Lenders, and may be removed, upon show of cause, by the Required Lenders upon 30
days' written notice to such Agent. Upon any such resignation or removal, the
Required Lenders shall have the right to appoint a successor Agent. If no
successor Agent shall have been so appointed by the Required Lenders, and shall
have accepted such appointment, within 30 days after the notice of resignation
or notice of removal, as appropriate, then the retiring Agent shall select a
successor Agent provided such successor is a Lender hereunder or a commercial
bank organized under the laws of the United States of America or of any State
thereof and has a combined capital and surplus of at least US$400,000,000. Upon
the acceptance of any appointment as Agent hereunder by a successor, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations as Agent, as
appropriate, under this Credit Agreement and the other Credit Documents and the
provisions of this Section 8 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Agent under this Credit Agreement.

         8.10     Intercreditor Agreement.

         Inasmuch as the obligations under the Revolving Credit Agreement are
secured by the same collateral as that securing the obligations under this
Credit Agreement, an intercreditor agreement is required in order that the
respective obligations share in such collateral on a pari passu basis. By
execution hereof, each Lender hereby acknowledges and agrees to be bound by the
terms of the Intercreditor Agreement and further authorizes and directs the
Collateral Agent to enter into the Intercreditor Agreement on its behalf.

         9.2      Right of Set-Off.

         In addition to any rights now or hereafter granted under applicable law
or otherwise, and not by way of limitation of any such rights, upon the
occurrence of an Event of Default, each Lender is authorized at any time and
from time to time, without presentment, demand, protest or other notice of any
kind (all of which rights being hereby expressly waived), to set-off and to
appropriate and apply any and all deposits (general or special) and any other
indebtedness at any time held or owing by such Lender (including, without
limitation branches, agencies or Affiliates of such Lender wherever located) to
or for the credit or the account of any Credit Party against obligations and
liabilities of such Person to such Lender hereunder, under the Term Notes, the
other Credit Documents or otherwise, irrespective of whether such Lender shall
have made any demand hereunder and although such obligations, liabilities or
claims, or any of them, may be contingent or unmatured, and any such set-off
shall be deemed to have been made immediately upon the occurrence of an Event of
Default even though such charge is made or entered on the books of such Lender
subsequent thereto. Any Person purchasing a participation in the Loans and
Commitments hereunder pursuant to Section 3.14 or Section 9.3(d) may exercise
all rights of set-off with respect to its participation interest as fully as if
such Person were a Lender hereunder.

         9.3      Benefit of Agreement.

         (a)      Generally. This Credit Agreement shall be binding upon and
inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto; provided that none of the Credit Parties may
assign or transfer any of its interests without prior written consent of the
Lenders; provided further that the rights of each Lender to transfer, assign or
grant participations in its rights and/or obligations hereunder shall be limited
as set forth in this Section 9.3, provided however that nothing herein shall
prevent or prohibit any Lender from (i) pledging its Loans hereunder to a
Federal Reserve Bank in support of borrowings made by such Lender from such
Federal Reserve Bank, or (ii) granting assignments or selling participations in
such Lender's Loans and/or Commitments hereunder to its parent company and/or to
any Affiliate or Subsidiary of such Lender.

         (b)      Assignments. Each Lender may assign all or a portion of its
rights and obligations hereunder (including, without limitation, all or a
portion of its Commitments or its Loans), pursuant to an assignment agreement
substantially in the form of Schedule 9.3(b), to (i) a Lender, (ii) an

                                       34

<PAGE>   39

affiliate of a Lender or (iii) any bank, financial institution, commercial
lender or institutional investor reasonably acceptable to the Administrative
Agent and, so long as no Default or Event of Default has occurred and is
continuing, the Borrower (the consent of the Borrower shall not be unreasonably
withheld or delayed); provided that (i) any such assignment (other than any
assignment to an existing Lender) shall be in a minimum aggregate amount of
US$5,000,000 (or, if less, the remaining amount of the Commitment being assigned
by such Lender) of the Commitments and in integral multiples of US$250,000 above
such amount and (ii) each such assignment shall be of a constant, not varying,
percentage of all such Lender's rights and obligations under this Credit
Agreement. Any assignment hereunder shall be effective upon delivery to the
Administrative Agent of written notice of the assignment together with a
transfer fee of US$3,500 payable to the Administrative Agent for its own account
from and after the later of (i) the effective date specified in the applicable
assignment agreement and (ii) the date of recording of such assignment in the
Register pursuant to the terms of subsection (c) below. The assigning Lender
will give prompt notice to the Administrative Agent and the Borrower of any such
assignment. Upon the effectiveness of any such assignment (and after notice to,
and (to the extent required pursuant to the terms hereof), with the consent of,
the Borrower as provided herein), the assignee shall become a "Lender" for all
purposes of this Credit Agreement and the other Credit Documents and, to the
extent of such assignment, the assigning Lender shall be relieved of its
obligations hereunder to the extent of the Loans and Commitment components being
assigned. Along such lines the Borrower agrees that upon notice of any such
assignment and surrender of the appropriate Term Note or Term Notes, it will
promptly provide to the assigning Lender and to the assignee separate promissory
notes in the amount of their respective interests substantially in the form of
the original Term Note (but with notation thereon that it is given in
substitution for and replacement of the original Term Note or any replacement
notes thereof). By executing and delivering an assignment agreement in
accordance with this Section 9.3(b), the assigning Lender thereunder and the
assignee thereunder shall be deemed to confirm to and agree with each other and
the other parties hereto as follows: (i) such assigning Lender warrants that it
is the legal and beneficial owner of the interest being assigned thereby free
and clear of any adverse claim; (ii) except as set forth in clause (i) above,
such assigning Lender makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made in or in connection with this Credit Agreement, any of the other Credit
Documents or any other instrument or document furnished pursuant hereto or
thereto, or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Credit Agreement, any of the other Credit Documents
or any other instrument or document furnished pursuant hereto or thereto or the
financial condition of any Credit Party or any of their respective Affiliates or
the performance or observance by any Credit Party of any of its obligations
under this Credit Agreement, any of the other Credit Documents or any other
instrument or document furnished pursuant hereto or thereto; (iii) such assignee
represents and warrants that it is legally authorized to enter into such
assignment agreement; (iv) such assignee confirms that it has received a copy of
this Credit Agreement, the other Credit Documents and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into such assignment agreement; (v) such assignee will
independently and without reliance upon the Agents, such assigning Lender or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Credit Agreement and the other Credit Documents;
(vi) such assignee appoints and authorizes the Agents

                                       35

<PAGE>   40

to take such action on its behalf and to exercise such powers under this Credit
Agreement or any other Credit Document as are delegated to the Agents by the
terms hereof or thereof, together with such powers as are reasonably incidental
thereto; and (vii) such assignee agrees that it will perform in accordance with
their terms all the obligations which by the terms of this Credit Agreement and
the other Credit Documents are required to be performed by it as a Lender.

         (c)      Maintenance of Register. The Administrative Agent shall
maintain at one of its offices in Charlotte, North Carolina a copy of each
Lender assignment agreement delivered to it in accordance with the terms of
subsection (b) above and a register for the recordation of the identity of the
principal amount, type and Interest Period of each Loan outstanding hereunder,
the names, addresses and the Commitments of the Lenders pursuant to the terms
hereof from time to time (the "Register"). The Administrative Agent will make
reasonable efforts to maintain the accuracy of the Register and to promptly
update the Register from time to time, as necessary. The entries in the Register
shall be conclusive in the absence of manifest error and the Borrower, the
Agents and the Lenders may treat each Person whose name is recorded in the
Register pursuant to the terms hereof as a Lender hereunder for all purposes of
this Credit Agreement. The Register shall be available for inspection by the
Borrower and each Lender, at any reasonable time and from time to time upon
reasonable prior notice.

         (d)      Participations. Each Lender may sell, transfer, grant or
assign participations in all or a portion of such Lender's rights, obligations
or rights and obligations hereunder (including all or a portion of its
Commitments or its Loans); provided that (i) such selling Lender shall remain a
"Lender" for all purposes under this Credit Agreement (such selling Lender's
obligations under the Credit Documents remaining unchanged) and the participant
shall not constitute a Lender hereunder, (ii) no such participant shall have, or
be granted, rights to approve any amendment or waiver relating to this Credit
Agreement or the other Credit Documents except to the extent any such amendment
or waiver would (A) reduce the principal of or rate of interest on or Fees in
respect of any Loans in which the participant is participating, (B) postpone the
date fixed for any payment of principal, interest or Fees in which the
participant is participating, (C) except as the result of or in connection with
a dissolution, merger or disposition of a Subsidiary permitted under Section 8.3
of the Incorporated Covenants, release the Borrower or substantially all of the
Guarantors from its or their obligations under the Credit Documents, or (D)
except as the result of or in connection with a Divestiture permitted under
Section 8.3(b) of the Incorporated Covenants, release all or substantially all
of the collateral, and (iii) sub-participations by the participant (except to an
affiliate, parent company or affiliate of a parent company of the participant)
shall be prohibited. In the case of any such participation, the participant
shall not have any rights under this Credit Agreement or the other Credit
Documents (the participant's rights against the selling Lender in respect of
such participation to be those set forth in the participation agreement with
such Lender creating such participation) and all amounts payable by the Borrower
hereunder shall be determined as if such Lender had not sold such participation,
provided, however, that such participant shall be entitled to receive additional
amounts under Sections 3.6, 3.9, 3.10, 3.11 and 9.2 on the same basis as if it
were a Lender.

         9.4      No Waiver; Remedies Cumulative.

         No failure or delay on the part of either Agent or any Lender in
exercising any right, power or privilege hereunder or under any other Credit
Document and no course of dealing between either Agent or any Lender and any of
the Credit Parties shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder or under any other
Credit Document preclude any other or further exercise thereof or the exercise
of any other right, power or privilege hereunder or thereunder. The rights and
remedies provided herein are cumulative and not exclusive of any rights or
remedies which either Agent or any Lender would otherwise have. No notice to or
demand on any Credit Party in any case shall entitle the Borrower or any other
Credit Party to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of the Agents or the Lenders
to any other or further action in any circumstances without notice or demand.

         9.5      Payment of Expenses, etc.

         The Borrower agrees to: (i) pay all reasonable out-of-pocket costs and
expenses (A) of the Agents in connection with the negotiation, preparation,
execution and delivery and administration of this Credit Agreement and the other
Credit Documents and the documents and instruments referred to therein
(including, without limitation, the reasonable fees and expenses of Moore & Van
Allen, PLLC, special counsel to the Agents) and any amendment, waiver or consent
relating hereto and thereto including, but not limited to, any such amendments,
waivers or consents resulting from or related to any work-out, renegotiation or
restructure relating to the performance by the Credit Parties under this Credit
Agreement and (B) of the Agents and the Lenders in connection with enforcement
of the Credit Documents and the documents and instruments referred to therein
(including, without limitation, in connection with any such enforcement, the
reasonable fees and disbursements of counsel for the Administrative Agent and
each of the Lenders); (ii) permit the Administrative Agent to perform inventory
and accounts receivable field audits at the Borrower's expense, provided that
unless an Event of Default shall be in existence the Borrower's obligation to
reimburse the Administrative Agent for such field audits shall be limited to one
such field audit each fiscal year; (iii) pay and hold each of the Lenders
harmless from and against any and all present and future stamp and other similar
taxes with respect to the foregoing matters and save each of the Lenders
harmless from and against any and all liabilities with respect to or resulting
from any delay or omission (other than to the extent attributable to such
Lender) to pay such taxes; and (iv) indemnify each Lender, its officers,
directors, employees, representatives and the Agents from and hold each of them
harmless against any and all losses, liabilities, claims, damages or expenses
incurred by any of them as a result of, or arising out of, or in any way related
to, or by reason of (A) any investigation, litigation or other proceeding
(whether or not any Lender is a party thereto) related to the entering into
and/or performance of any Credit Document or the use of proceeds of any Loans
(including other Extensions of Credit) hereunder or the consummation of any
other transactions contemplated in any Credit Document, including, without
limitation, the reasonable fees and disbursements of counsel incurred in
connection with any such investigation, litigation or other proceeding or (B)
the presence or Release of any Materials of Environmental Concern at, under or
from any Property owned, operated or leased by the Borrower or any of its
Subsidiaries, or the failure by the Borrower or any of its Subsidiaries to
comply with any Environmental Law (but

                                       37
<PAGE>   42

excluding, in the case of either of clause (A) or (B) above, any such losses,
liabilities, claims, damages or expenses to the extent incurred by reason of
gross negligence or willful misconduct on the part of the Person to be
indemnified).

         9.6      Amendments, Waivers and Consents.

         Neither this Credit Agreement nor any other Credit Document nor any of
the terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing entered into by, or approved in writing by, the Required Lenders and the
Borrower, provided, however, that:

         (a)      without the consent of each Lender affected thereby, neither
         this Credit Agreement nor any of the other Credit Documents may be
         amended to

                        (i)    extend the final maturity of any Loan (other than
                   the waiver of any mandatory prepayment required by Section
                   3.3(b)),

                        (ii)   reduce the rate or extend the time of payment of
                   interest thereon or Fees hereunder (other than as a result of
                   waiving the applicability of any increase in interest rates
                   or Fees after the occurrence of an Event of Default or on
                   account of a failure to deliver financial statements on a
                   timely basis),

                        (iii)  reduce or waive the principal amount of any Loan,

                        (iv)   increase the Commitment of a Lender over the
                   amount thereof in effect (it being understood and agreed that
                   a waiver of any mandatory prepayment required by Section
                   3.3(b) or a waiver of any Default or Event of Default shall
                   not constitute an increase in the Commitment of any Lender),

                        (v)    except as the result of or in connection with a
                  dissolution, merger or disposition of a Subsidiary permitted
                  under Section 8.3 of the Incorporated Covenants, release the
                  Borrower or substantially all of the Guarantors from its or
                  their obligations under the Credit Documents,

                        (vi)   except as the result of or in connection with a
                   Divestiture permitted under Section 8.3(b) of the
                   Incorporated Covenants, release all or substantially all of
                   the collateral,

                        (vii)  amend, modify or waive any provision of this
                   Section 9.6 or Section 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.13,

                   modify, the definition of Required Lenders, or

                        (ix)   consent to the assignment or transfer by the
                   Borrower (or another Credit Party) of any of its rights and
                   obligations under (or in respect of) the Credit Documents
                   except as permitted thereby;

                   (b)   without the consent of the Administrative Agent, no
         provision of Section 8 may be amended;

         Notwithstanding the fact that the consent of all the Lenders is
required in certain circumstances as set forth above, (x) each Lender is
entitled to vote as such Lender sees fit on any bankruptcy reorganization plan
that affects the Loans, and each Lender acknowledges that the provisions of
Section 1126(c) of the Bankruptcy Code supersedes the unanimous consent
provisions set forth herein and (y) the Required Lenders may consent to allow a
Credit Party to use cash collateral in the context of a bankruptcy or insolvency
proceeding.

         9.7      Counterparts.

         This Credit Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be an original, but all of

making proof of this Credit Agreement to produce or account for more than one
such counterpart.

         9.8      Headings.

         The headings of the sections and subsections hereof are provided for
convenience only and shall not in any way affect the meaning or construction of
any provision of this Credit Agreement.

         9.9      Survival.

         All indemnities set forth herein, including, without limitation, in

hereunder, and all representations and warranties made by the Credit Parties
herein shall survive delivery of the Term Notes and the making of the Loans

         (c)      Each of the Credit Parties hereby irrevocably waives any

PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS CREDIT AGREEMENT,
ANY OF THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         9.11     Severability.

         If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

         9.12     Entirety.

         This Credit Agreement together with the other Credit Documents
represent the entire agreement of the parties hereto and thereto, and supersede

<PAGE>   45

         (b)      The term of this Credit Agreement shall commence on the
effective date pursuant to subsection (a) above and shall continue until no
Loans or any other amounts payable hereunder or under any of the other Credit
Documents shall remain outstanding and until all of the Commitments hereunder
shall have expired or been terminated.

         9.14     Confidentiality.

         The Administrative Agent and the Lenders agree to keep confidential
(and to cause their respective affiliates, officers, directors, employees,
agents and representatives to keep confidential) all information, materials and
documents furnished to the Administrative Agent or any such Lender by or on
behalf of any Credit Party (whether before or after the Closing Date) which
relates to the Borrower or any of its Subsidiaries (the "Information").
Notwithstanding the foregoing, the Administrative Agent and each Lender shall be
permitted to disclose Information (i) to its affiliates, officers, directors,
employees, agents and representatives in connection with its participation in
any of the transactions evidenced by this Credit Agreement or any other Credit
Documents or the administration of this Credit Agreement or any other Credit
Documents, subject to the provisions of this Section 9.14; (ii) to the extent
required by applicable laws and regulations or by any subpoena or similar legal
process, or requested by any Governmental Authority; (iii) to the extent such
Information (A) becomes publicly available other than as a result of a breach of
this Credit Agreement or any agreement entered into pursuant to clause (iv)
below, (B) becomes available to the Administrative Agent or such Lender on a
non-confidential basis from a source other than a Credit Party or (C) was
available to the Administrative Agent or such Lender on a non-confidential basis
prior to its disclosure to the Administrative Agent or such Lender by a Credit
Party; (iv) to any assignee or participant (or prospective assignee or
participant) so long as such assignee or participant (or prospective assignee or
participant) first specifically agrees in a writing furnished to and for the
benefit of the Credit Parties to be bound by the terms of this Section 9.14; or
(v) to the extent that the Borrower shall have consented in writing to such
disclosure. Nothing set forth in this Section 9.14 shall obligate the
Administrative Agent or any Lender to return any materials furnished by the
Credit Parties.

         9.15     Source of Funds.

         Each of the Lenders hereby represents and warrants to the Borrower that
at least one of the following statements is an accurate representation as to the
source of funds to be used by such Lender in connection with the financing
hereunder:

                  (a)      no part of such funds constitutes assets allocated to
         any separate account maintained by such Lender in which any employee
         benefit plan (or its related trust) has any interest;

                  (b)      to the extent that any part of such funds constitutes
         assets allocated to any separate account maintained by such Lender,
         such Lender has disclosed to the Borrower the name of each employee
         benefit plan whose assets in such account exceed 10% of the total
         assets of such account as of the date of such purchase (and, for
         purposes of this subsection

                                       41

<PAGE>   46

         (b), all employee benefit plans maintained by the same employer or
         employee organization are deemed to be a single plan);

                  (c)      to the extent that any part of such funds constitutes
         assets of an insurance company's general account, such insurance
         company has complied with all of the requirements of the regulations
         issued under Section 401(c)(1)(A) of ERISA; or

                  (d)      such funds constitute assets of one or more specific
         benefit plans which such Lender has identified in writing to the
         Borrower.

As used in this Section 9.15, the terms "employee benefit plan" and "separate
account" shall have the respective meanings assigned to such terms in Section 3
of ERISA.

         9.16     Conflict.

         To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document, on
the other hand, this Credit Agreement shall control.

         9.17     Senior Subordinated Note Indenture.

         The Borrower hereby (a) acknowledges and agrees that the Indebtedness
evidenced by this Agreement and the other Credit Documents constitutes Senior
Debt as defined in the Senior Subordinated Note Indenture, (b) specifically
designates the Indebtedness evidenced by this Agreement and the other Credit
Documents (specifically including all Obligations) as "Designated Senior Debt"
for all purposes, including without limitation for purposes of the Senior
Subordinated Note Indenture and (c) agrees that it will not designate any other
Indebtedness incurred by it as "Designated Senior Debt" without the prior
written consent of the Required Lenders.

                        Form of Assignment and Acceptance

         THIS ASSIGNMENT AND ACCEPTANCE dated as of , 199_ is entered into
between THE LENDER IDENTIFIED ON THE SIGNATURE PAGES AS THE "ASSIGNOR" (the
"Assignor") and THE PARTY IDENTIFIED ON THE SIGNATURE PAGES AS "ASSIGNEE"
("Assignee").

         Reference is made to that Term Loan Credit Agreement dated as of
November 5, 1999 (as amended and modified from time to time, the "Credit
Agreement") among RailWorks Corporation, a Delaware corporation (the
"Borrower"), the Subsidiaries of the Borrower identified therein, the Lenders
identified therein and Bank of America, N.A., as Administrative Agent. Terms
defined in the Credit Agreement are used herein with the same meanings.

         1.       The Assignor hereby sells and assigns, without recourse, to
the Assignee, and the Assignee hereby purchases and assumes, without recourse,
from the Assignor, effective as of the Effective Date shown below, those rights
and interests of the Assignor under the Credit Agreement identified below (the
"Assigned Interests"), including the Loans and Commitments relating thereto,
together with unpaid interest and fees relating thereto accruing from the
Effective Date. The Assignor represents and warrants that it owns interests
assigned hereby free and clear of liens, encumbrances or other claims. The
Assignee represents that it is a permitted assignee under Section 9.3(b) of the
Credit Agreement. The Assignor and the Assignee hereby make and agree to be
bound by all the representations, warranties and agreements set forth in Section

thereunder and (ii) the Assignor shall, to the extent of the interests assigned
by this Assignment and Acceptance, relinquish its rights and be released from
its obligations under the Credit Agreement (other than the rights of
