                           RECAPITALIZATION AGREEMENT

     THIS RECAPITALIZATION AGREEMENT (this "Agreement") is made as of
March 27, 2000 by and among ZEFER Corp., a Delaware corporation (the
"Company"), GTCR Capital Partners, L.P., a Delaware limited partnership ("GTCR
Capital"), GTCR Fund VI, L.P., a Delaware limited partnership ("GTCR Fund VI"),
GTCR VI Executive Fund, L.P., a Delaware limited partnership ("Executive Fund"),
GTCR Associates VI, a Delaware general partnership ("Associates Fund" and,
together with GTCR Capital, GTCR Fund VI and the Executive Fund, the "GTCR
Investors"), and the other stockholders of the Company set forth on the
signature pages hereto (together with the GTCR Investors, the "Stockholders").
Except as otherwise indicated herein, capitalized terms used herein are defined
in Section 6 hereof.

     Each Stockholder owns the number of shares of the Company's Class A
Preferred Stock, par value $.01 per share (the "Class A Preferred") set forth
opposite such Stockholder's name on the Schedule of Stockholders attached
hereto.

     Section 4B of Part B of Article Four of the Company's Restated Certificate
of Incorporation, as amended through the date hereof (the "Certificate"),
provides that the Company shall, at the request of the holders of a majority of
the Class A Preferred, apply the net cash proceeds from any public offering of
equity securities to redeem the outstanding shares of Class A Preferred at a
price equal to the liquidation value thereof plus accrued and unpaid dividends
thereon.

     The Company has filed a Registration Statement on Form S-1 (File No.
333-94283) (the "Registration Statement") with the Securities and Exchange
Commission relating to an initial public offering (the "Initial Public
Offering") of the Company's common stock, par value $0.001 per share (the
"Common Stock"), under the Securities Act. The Stockholders desire that the
Company redeem the shares of Class A Preferred with the net proceeds of the
Initial Public Offering after payment of underwriting discounts and reasonable
out-of-pocket fees and expenses incurred in connection therewith (the "Net
Proceeds"). However, the Company desires to use a portion of the Net Proceeds to
fully repay the GTCR Indebtedness and the Harris Indebtedness (collectively, the
"Indebtedness"), and to maintain a portion of the Net Proceeds for working
capital and other general corporate purposes. As a result, if the Company
receives Net Proceeds less than the amounts set forth in this Agreement, there
may not be any Net Proceeds remaining to redeem outstanding shares of Class A
Preferred.

     As such, the Stockholders and the Company desire to enter into an agreement
pursuant to which the Net Proceeds will be applied in the following order and
manner: (i) first, the Net Proceeds will be used to fully repay the Harris
Indebtedness; (ii) second, an additional amount of Net Proceeds, if any, not to
exceed $23,400,000 shall be retained by the Company for working capital and
other general corporate purposes; (iii) third, an additional amount of Net
Proceeds, if any, not to exceed $33,200,000 in the aggregate shall be divided
evenly with (a) one-half of such amount applied to repay the GTCR Indebtedness
and (b) the other half of such amount retained by the Company for working
capital and
<PAGE>

other general corporate purposes; (iv) fourth, an additional amount
of Net Proceeds, if any, shall be applied to repay the remaining GTCR
Indebtedness; and (v) fifth, the remaining Net Proceeds, if any (the "Excess Net
Proceeds"), will be used by the Company to redeem shares of Class A Preferred;
provided that to the extent that the Excess Net Proceeds are not sufficient to
redeem all shares of Class A Preferred, the remaining shares of Class A
Preferred shall be exchanged for shares of Common Stock (the "Exchange Shares").
In addition, to the extent the underwriters of the Initial Public Offering
exercise their over-allotment option, the Excess Net Proceeds resulting from
such exercise, if any, will be used by the Company to redeem Exchange Shares
from the Stockholders on a pro rata basis according to the number of Exchange
Shares received by each Stockholder at a redemption price per share equal to the
initial offering price for a share of Common Stock in the Initial Public
Offering.

     The parties hereto agree as follows:

     Section 1. Application of Net Proceeds; Redemption; Exchange; and Closing.

     1A. Application of Net Proceeds; Redemption. At the Closing (as defined in
Section 1C below), the Company shall apply the Net Proceeds as follows: (i)
first, the Net Proceeds shall be used to fully repay the Harris Indebtedness;
(ii) second, an additional amount of Net Proceeds, if any, not to exceed
$23,400,000 shall be retained by the Company for working capital and other
general corporate purposes; (iii) third, an additional amount of Net Proceeds,
if any, not to exceed $33,200,000 in the aggregate shall be divided evenly with
(a) one-half of such amount applied to repay the GTCR Indebtedness and (b) the
other half of such amount retained by the Company for working capital and other
general corporate purposes; (iv) fourth, an additional amount of Net Proceeds,
if any, shall be applied to repay the remaining GTCR Indebtedness; and (v)
fifth, the Excess Net Proceeds, if any, shall be used to redeem shares of Class
A Preferred from each Stockholder on a pro rata basis according to the aggregate
liquidation value and accrued and unpaid dividends of the Class A Preferred held
by such Stockholder. The redemption price for each share of Class A Preferred
shall equal the liquidation value thereof plus accrued and unpaid dividends
thereon. The redemption of the Class A Preferred pursuant to this Section 1A is
referred to herein as the "Redemption." At the Closing, each Stockholder shall
tender to the Company the shares of Class A Preferred held by such Stockholder
that are being redeemed pursuant to the Redemption duly endorsed for transfer to
the Company. As described below in Section 1B, each Stockholder shall have the
right to receive Exchange Shares in exchange for any shares of Class A Preferred
not so redeemed.

     1B. Exchange of the Remaining Shares of Class A Preferred Stock. At the
Closing, each Stockholder will exchange, in accordance with this Section 1B, all
shares of Class A Preferred held by such Stockholder that have not been redeemed
pursuant to Section 1A for Exchange Shares. At the Closing, the Company shall
issue to each Stockholder a number of shares


                                     - 2 -
<PAGE>

of Common Stock equal to (i) the aggregate liquidation value of the shares of
Class A Preferred, if any, held by such Stockholder after giving effect to the
Redemption, plus the aggregate value of all accrued and unpaid dividends on such
shares of Class A Preferred, divided by (ii) the initial offering price of a
share of Common Stock in the Initial Public Offering. At the Closing, each
Stockholder shall deliver to the Company certificates representing all shares of
Class A Preferred, if any, held by such Stockholder after giving effect to the
Redemption, duly endorsed for transfer to the Company. If a fractional share of
Exchange Shares would be issuable to a Stockholder pursuant to this Section 1B,
the Company shall deliver to such Stockholder cash in lieu of such fractional
share in an amount equal to the percentage of a share represented by such
fractional interest multiplied by the initial offering price of a share of
Common Stock in the Initial Public Offering.

     1C. The Closing. The closing of the transactions contemplated by this
Section 1 (the "Closing") shall take place concurrently with the consummation of
the Initial Public Offering and at the same location. As of the Closing, all
shares of outstanding Class A Preferred shall automatically be canceled and
retired and cease to exist, and each holder of a certificate representing any
such shares shall cease to have any rights with respect thereto, except the
right to receive the Recapitalization Consideration therefor upon the surrender
of such certificate in the manner provided in this Section 1C. At the Closing
and thereafter, upon presentment and delivery by each such Stockholder to the
Company of the certificates representing the shares of Class A Preferred held by
such Stockholder duly endorsed for transfer to the Company, the Company (i)
shall pay to each Stockholder, by wire transfer of immediately available funds
to an account or accounts designated by such Stockholder, the aggregate
redemption price for such Stockholder's shares of Class A Preferred being
redeemed, (ii) shall deliver, or cause the Company's transfer agent to deliver,
to each Stockholder stock certificates evidencing the Exchange Shares to be
issued by the Company to each such Stockholder, registered in each such
Stockholder's name or its nominee's name, and (iii) shall deliver to each
Stockholder cash for any fractional shares of Exchange Stock to which such
Stockholder would otherwise be entitled (collectively, the "Recapitalization
Consideration"). Until surrendered as contemplated in this Section 1C, each
certificate representing Class A Preferred shall be deemed at any time after the
Closing to represent only the right to receive the Recapitalization
Consideration. Each certificate for Exchange Shares shall be imprinted with a
legend in substantially the following form:

     The shares represented by this certificate have not been registered under
     the Securities Act of 1933 (the "Act") or applicable state securities law
     and may not be sold or transferred unless (i) a registration statement
     covering such shares is effective under the Act or (ii) the transaction is
     exempt from registration under the Act and an opinion reasonably
     satisfactory to the Company to such effect has been rendered by counsel.

     Section 2. Application of Over-Allotment Proceeds; Redemption; and Closing.

     2A. Application of Over-Allotment Proceeds; Redemption of Exchange Shares.
Notwithstanding anything to the contrary in Section 1 above, to the extent that
the underwriters of the Initial Public Offering exercise their over-allotment
option from time to time, and to the extent that any of the Net Proceeds of such
exercise constitute Excess Net Proceeds, the Company shall,



                                     - 3 -
<PAGE>

upon receipt of the Excess Net Proceeds resulting from such exercise(s), use
such Excess Net Proceeds of such exercise to redeem a number of Exchange Shares
equal to (i) the amount of Excess Net Proceeds received by the Company from such
exercise, divided by (ii) the initial public offering price for a share of
Common Stock in the Initial Public Offering (each an "Exchange Share
Redemption"). At each Exchange Share Redemption, each Stockholder will present
and deliver certificates representing all Exchange Shares being redeemed from
such Stockholder, duly endorsed for transfer to the Company. In connection with
each Exchange Share Redemption, the Company shall redeem such Exchange Shares
from the Stockholders on a pro rata basis according to the number of Exchange
Shares received by each Stockholder pursuant to Section 1B above, in each case
at a redemption price per share equal to the initial offering price for a share
of Common Stock in the Initial Public Offering.

     2B. The Closing of Exchange Share Redemptions. The closing of each Exchange
Share Redemption shall take place concurrently with and at the same location as
the Company's issuance of Common Stock in connection with the underwriters'
related exercise of their over-allotment option. As of such closing, all
Exchange Shares to be redeemed in connection with such Exchange Share Redemption
shall automatically be canceled and retired and cease to exist, and each holder
of a certificate representing any such Exchange Shares shall cease to have any
rights with respect to such Exchange Shares, except the right to receive the
Exchange Share Redemption Consideration therefor upon the surrender of such
certificate in the manner provided in this Section 2B. At such closing and
thereafter, upon presentment and delivery by each such Stockholder to the
Company of the certificate(s) representing such Exchange Shares held by such
Stockholder duly endorsed for transfer to the Company, the Company shall (i) pay
to such Stockholder, by wire transfer of immediately available funds to an
account or accounts designated by such Stockholder, the redemption price for
each Exchange Share being redeemed from such Stockholder and (ii) deliver, or
cause the Company's transfer agent to deliver, to each Stockholder a new stock
certificate evidencing the remaining Exchange Shares that are not being redeemed
at such Exchange Share Redemption, if any, held by such Stockholder, registered
in such Stockholder's name or its nominee's name (collectively, the "Exchange
Share Redemption Consideration").

     Section 3. Conditions of Each Stockholder's Obligation at the Closing. The
obligation of each Stockholder to deliver its shares of Class A Preferred for
redemption and exchange hereunder at the Closing is subject to the satisfaction
as of the Closing of the following conditions:

     this Agreement are inserted for convenience only and do not constitute a
     substantive part of this Agreement. The use of the word "'including" in
     this Agreement shall be by way of example rather than by limitation.

          8I. Governing Law. The laws of Delaware shall govern all issues
     concerning the relative rights of the Company and its stockholders and all
     other questions concerning the construction, validity and interpretation of
     this Agreement, without giving effect to any choice of law or other
     conflict of law provision or rule (whether of the State of Delaware or any
     other jurisdiction) that would cause the application of the laws of any
     jurisdiction other than the State of Delaware.
