     WARRANT AGREEMENT dated as of November 25, 1997 between Consolidation
Capital Corporation, a Delaware corporation (the "Company"), and Jonathan J.
Ledecky, a resident of the District of Columbia ("Mr. Ledecky").

                                 W I T N E S S E T H:

     WHEREAS, the Company proposes to issue to Mr. Ledecky warrants ("Warrants")
to purchase 1,950,000 shares of common stock, par value $.001 per share ("Common
Stock"), on the closing date of the initial public offering (the shares of
Common Stock covered by the Warrants are referred to as the "Shares");

     WHEREAS the Company in connection with its initial public offering has
entered into an underwriting agreement with Friedman, Billings, Ramsey & Co.,
Inc. dated November 25, 1997 (the "Underwriting Agreement"); and

     WHEREAS, the Warrants issued pursuant to this Agreement are being issued by
the Company to Mr. Ledecky in connection with the Company's initial public
offering and in view of his interest in having the ability to purchase
additional shares of Common Stock in the Company;

     NOW, THEREFORE, in consideration of the premises and the agreements herein
set forth and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto agree as follows:

     1.  GRANT.

     Mr. Ledecky is hereby granted the right to purchase, at any time from
November 25, 1997  until 5:00 p.m., Washington, D.C. time, on November 25, 2007
(the "Warrant Exercise Term"), 1,950,000 shares of Common Stock on the closing
date of the initial public offering at an initial exercise price (subject to
adjustment as provided in Article 7 hereof) of $20.00 per Share.  Except as
provided in Section 12 hereof, the Shares are in all respects identical to the
public shares being sold to the public pursuant to the terms and provisions of
the Underwriting Agreement.

     2.  WARRANT CERTIFICATES.

     The warrant certificates (the "Warrant Certificates") delivered and to be
delivered pursuant to this Agreement shall be in the form set forth as Exhibit
A, attached hereto and made a part hereof, with such appropriate insertions,
omissions, substitutions and other variations as required or permitted by this
Agreement.
<PAGE>

     3.  EXERCISE OF WARRANTS.

     3.1  CASH EXERCISE.  The Warrants initially are exercisable at a price of
$20.00 per Share purchased, payable in cash or by check to the order of the
Company, or any combination of cash or check, subject to adjustment as provided
in Article 7 hereof.  Upon surrender of the Warrant Certificate with the annexed
Form of Election to Purchase duly executed, together with payment of the
Exercise Price (as hereinafter defined) for the Shares purchased, at the
principal office of the Company (presently located at 1747 Pennsylvania Avenue,
NW, Suite 900, Washington, D.C. 20006) or at the office of its transfer agent,
the registered holder(s) of a Warrant Certificate ("Holder" or "Holders") shall
be entitled to receive a certificate or certificates for the Shares so
purchased.  The purchase rights represented by each Warrant Certificate are
exercisable at the option of the Holder hereof, in whole or in part (but not as
to fractional Shares).  In the case of the purchase of less than all of the
Shares purchasable under any Warrant Certificate, the Company shall cancel said
Warrant Certificate upon the surrender thereof and shall execute and deliver a
new Warrant Certificate of like tenor for the balance of the Shares purchasable
thereunder.



     4.  RESTRICTION ON TRANSFER.

     The Holder of a Warrant Certificate, by its acceptance thereof, covenants
and agrees that the Warrants are being acquired as an investment and not with a
view to the distribution thereof, and that the Warrants may not be sold,
transferred, assigned, hypothecated or otherwise disposed of, in whole or in
part, except (i) to officers, directors or affiliates of Mr. Ledecky or (ii) to
transferees whom with the opinion of counsel, acceptable to the Company and the
transferor, that such transfer is exempt from registration under the Securities
Act of 1933, as amended (the "Act").  The Warrant Certificate issued pursuant to
(ii) above will bear a legend stating that the Warrants may only be exercised if
there is an applicable exemption under the Act, for the issuance of shares of
Common Stock of the Company upon the exercise of the Warrants.

     Additionally, upon exercise, in part or in whole, of the Warrants,
certificates representing the Shares shall bear a legend substantially similar
to the following:

     "The securities represented by this certificate and the other securities
     issuable upon exercise thereof have not been registered under the Act, and
     may not be offered or sold except (i) pursuant to an effective registration
     statement under the Act, (ii), to the extent applicable, pursuant to Rule
     144 under the Act (or any similar rule under such Act relating to the
     disposition of securities), or (iii) upon the delivery by the holder to the
     Company of an opinion of counsel, reasonably satisfactory to counsel to the
     Company, stating that an exemption from registration under such Act is
     available."
<PAGE>

     5.  PRICE.

     5.1  INITIAL AND ADJUSTED EXERCISE PRICE.  The initial exercise price of
each Warrant shall be $20.00 per Share.  The adjusted exercise price shall be
the price which shall result from time to time from any and all adjustments of
the initial exercise price in accordance with the provisions of Article 7
hereof.

     5.2  EXERCISE PRICE.  The term "Exercise Price" herein shall mean the
initial exercise price or the adjusted exercise price, depending upon the
context.


     6.  REGISTRATION RIGHTS.

     6.1  REGISTRATION UNDER THE SECURITIES ACT OF 1933.  None of the Warrants
nor the Shares have been registered for purposes of public distribution under
the Act.

     6.2  REGISTRABLE SECURITIES.  As used herein the term "Registrable
Security" means each of the Shares and any Common Stock issued upon any stock
split or stock dividend in respect of such Shares; provided, however, that with
respect to any particular Registrable Security, such security shall cease to be
a Registrable Security when, as of the date of determination, (i) it has been
effectively registered under the Act and disposed of pursuant thereto, (ii)
registration under the Act is no longer required for subsequent sale of such
security or (iii) it has ceased to be outstanding.  The term "Registrable
Securities" means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security."  In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Common Stock, such adjustment shall be made in the
definition of "Registrable Security" as is appropriate in order to prevent any
dilution or enlargement of the rights granted pursuant to this Article 7.

     6.3  PIGGYBACK REGISTRATION.

          (a) If, at any time during the twelve years following the date of this
Agreement, the Company proposes to prepare and file one or more registration
statement(s) filed in connection with a public offering covering equity
securities of the Company, or any such securities of the Company held by its
shareholders (other than in connection with an exchange offer, a "rights"
offering to shareholders, an offering relating to an employee benefit plan,
dividend reinvestment plan, an acquisition, a merger, the conversion of any
convertible securities, an exchange of a security, or a stand-by underwriting
with respect to the call of a warrant, option, right or convertible security for
redemption), (for purposes of this Article 7, collectively, a "Registration
Statement"), it will give written notice of its intention to do so by registered
mail ("Notice"), at least thirty (30) business days prior to the filing of each
such Registration Statement, to all holders of the Registrable Securities or, in
the event that the Company has not formulated its intent to file such
Registration Statement at least thirty (30) calendar days before the anticipated
filing date of the Registration Statement, as soon as practicable upon the
formation by the Company of such intent.  However, no such Notice need
<PAGE>

be given if the Registration Statement is for an underwritten offering of
securities other than equity securities or securities convertible into equity
securities. Upon the written request of such a holder (a "Requesting Holder"),
made within twenty (20) business days after receipt of the Notice, that the
Company include any of the Requesting Holder's Registrable Securities in the
proposed Registration Statement, the Company shall, as to each such Requesting
Holder, use its best efforts to effect the registration under the Act of the
Registrable Securities which it has been so requested to register ("Piggyback
Registration"), at the Company's sole cost and expense and at no cost or expense
to the Requesting Holders. The Company shall not be required to honor any such
request (i) if, in the opinion of counsel to the Company reasonably acceptable
to such Holder who wishes to have such Registrable Securities included in such
Registration Statement, registration under the Act is not required for the
transfer of the Registrable Securities in the manner proposed by such Holder; or
(ii) to register in the aggregate fewer than 25,000 Shares held by the Holders.
The Company shall permit, or shall use its best efforts to cause the managing
underwriter of a proposed offering to permit, the Holders of Registrable
Securities requested to be included in the registration (the "Piggy-Back
Shares") to include such Piggy-Back Shares in the proposed offering on the same
terms and conditions as applicable to the shares of Common Stock offered by the
Company and for the account of any person other than the Company, as the case
may be.

          (b) Notwithstanding the foregoing, if any such managing underwriter
shall advise the Company in writing that, in its opinion, the distribution of
all or a portion of the Registrable Securities requested to be included in the
Registration Statement concurrently with the shares of Common Stock being
registered by the Company would materially adversely affect the distribution of
such securities by the Company for its own account, or for the account of any
person or persons other than the Company that have asserted, with respect to
such registration, demand registration rights under any other agreement, then
such inclusion of Registrable Securities shall be made pro rata among the
aggregate of the Registrable Securities for which a proper request was made
under this subsection 6.3 and any other securities properly requested to be
included in the registration by other holders pursuant to piggy-back or
incidental registration rights under any other agreement.

     6.4  DEMAND REGISTRATION.

          (a) At any time during the Warrant Exercise Term, any "Majority
Holder" (as such term is defined in Section 6.4(c) below) of the Registrable
Securities shall have the right (which right is in addition to the piggyback
registration rights provided for under Section 6.3 hereof), exercisable by
written notice to the Company (the "Demand Registration Request"), to have the
Company prepare and file with the Securities and Exchange Commission (the
"Commission"), on one occasion, at the sole expense of the Company, a
Registration Statement and such other documents, including a prospectus, as may
be necessary (in the opinion of both counsel for the Company and counsel for
such Majority Holder), in order to comply with the provisions of the Act, so as
to permit a public offering and sale of the Registrable Securities by the
holders thereof, for twelve (12) consecutive months.  The Company shall not be
required to file any amendments to the Registration Statement required by this
subsection 6.4(a) except as is necessary to keep the disclosure about the
Company current.
<PAGE>

          (b) The Company covenants and agrees to give written notice of any
Demand Registration Request to all holders of the Registrable Securities within
ten (10) days from the date of the Company's receipt of any such Demand
Registration Request.  After receiving notice from the Company as provided in
this Section 6.4(b), holders of Registrable Securities may request the Company
to include their Registrable Securities in the Registration Statement to be
filed pursuant to Section 6.4(a) hereof by notifying the Company of their
decision to include such securities within ten (10) days of their receipt of the
Company's notice.

          (c) The term "Majority Holder" as used in this Section 6.4 shall mean
any holder or any combination of holders of Registrable Securities, if included
in such holders' Registrable Securities are that aggregate number of Shares
(including Shares already issued and Shares issuable pursuant to the exercise of
outstanding Warrants) as would constitute a majority of the aggregate number of
Shares (including Shares already issued and Shares issuable pursuant to the
exercise of outstanding Warrants) included in all of the Registrable Securities.

     6.5  COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.  The Company
covenants and agrees as follows:

          (a) In connection with any registration under Section 6.4 hereof, the
Company shall file the Registration Statement as expeditiously as possible, but
in no event later than thirty (30) days following receipt of any demand
therefor, shall use its best efforts to have any such Registration Statement
declared effective at the earliest possible time.  If a written request,
however, is received by the Company that would require the filing of a
Registration Statement between 45 and 105 days after the end of its fiscal year,
the deadline for the filing of the Registration Statement shall be extended
until the 106th day of such fiscal year.  The Company shall furnish each holder
of Registrable Securities such number of prospectuses as shall reasonably be
requested.  However, in connection with any registration under Sections 6.3 and
6.4 hereof, the Company shall have sole control in connection with the
preparation, filing, amending and supplementing of the Registration Statement,
including the right to withdraw the same or delay the filing or effectiveness
thereof when, in the sole judgment of the Board of Directors of the Company, the
filing or pendency of such registration statement or the effectiveness thereof
would impose an undue burden upon the ability by the Company to proceed with any
other material financing for its own account or any material corporate
transaction, including, but not limited to, a reorganization, recapitalization,
merger, consolidation or material acquisition of the securities or assets of
another firm or corporation; provided, however, that the Company's exercise of
any such right of withdrawal or delay shall not be deemed a waiver of the rights
of the Holders, and the Company shall be required to file a new Registration
Statement or to proceed with such actions as reasonably may be required to cause
the Registration Statement to become effective within a reasonable time after
the consummation of the event or transaction which required such withdrawal or
delay.

          (b) The Company shall pay all costs, fees and expenses in connection
with all Registration Statements filed pursuant to Sections 6.3 and 6.4(a)
hereof including, without limitation, the Company's legal and accounting fees,
printing expenses, and blue sky fees and
<PAGE>

expenses. Each Holder, however, shall pay the underwriting discount attributable
to such Holder's Registrable Securities, any transfer tax payable with respect
thereto and the fees and expenses of such Holder's counsel.

          (c) The Company will take all necessary action which may be required
in qualifying or registering the Registrable Securities included in a
Registration Statement for offering and sale under the securities or blue sky
laws of such states as are requested by the holders of such securities, provided
that the Company shall not be obligated to execute or file any general consent
to service of process or to qualify as a foreign corporation to do business
under the laws of any such jurisdiction.

          (d) The Company shall indemnify any holder of the Registrable
Securities to be sold pursuant to any Registration Statement and any underwriter
or person deemed to be an underwriter under the Act and each person, if any, who
controls such holder or underwriter or person deemed to be an underwriter within
the meaning of Section 15 of the Act or Section 20(a) of the Securities Exchange
Act of 1934, as amended ("Exchange Act"), against all loss, claim, damage,
expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which any
of them may become subject under the Act, the Exchange Act or otherwise, arising
from such Registration Statement to the same extent and with the same effect as
the provisions pursuant to which the Company has agreed to indemnify the
underwriters contained in Section 8 of the Underwriting Agreement and shall
provide for just and equitable contribution as set forth in Section 8 of the
Underwriting Agreement.

          (e) Any holder of Registrable Securities to be sold pursuant to a
Registration Statement, and its successors and assigns, shall severally, and not
jointly, indemnify the Company, its officers and directors and each person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, against all loss, claim, damage or expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which they may become
subject under the Act, the Exchange Act or otherwise, arising from information
furnished in writing by or on behalf of such holder, or its successors or
assigns, for specific inclusion in such Registration Statement to the same
extent and with the same effect as the provisions contained in Section 8 of the
Underwriting Agreement pursuant to which the underwriters have agreed to
indemnify the Company and shall provide for just and equitable contribution as
set forth in Section 8 of the Underwriting Agreement.

          (f) Nothing contained in this Agreement shall be construed as
requiring any Holder to exercise his Warrants prior to the initial filing of any
Registration Statement or the effectiveness thereof.

          (g) If the Company shall fail to comply with the provisions of this
Article 6, the Company shall, in addition to any other equitable or other relief
available to the holders of Registrable Securities, be liable for any or all
incidental, special and consequential damages
<PAGE>

sustained by the holders of Registrable Securities that request registration of
their Registrable Securities.

          (h) Except as set forth in Section 6.5(j) hereof, the Company shall
not permit the inclusion of any securities other than the Registrable Securities
to be included in any Registration Statement filed pursuant to Section 6.4
hereof, or permit a Registration Statement relating to an underwritten offering
of the same securities as the Registrable Securities to be filed during an
underwritten offering of the Registrable Securities covered by a Registration
Statement filed pursuant to Section 7.4 hereof, without the prior written
consent of the Majority Holders, which consent shall not be unreasonably
withheld.

          (i) The Company shall deliver promptly to each holder of Registrable
Securities participating in the offering in which such Holder's shares are being
registered pursuant to Section 6.3 hereof and requesting the correspondence and
memoranda described in this Section 6.5(i) and to the managing underwriter, if
any, copies of all correspondence between the Commission and the Company, its
counsel or auditors and all memoranda relating to discussions with the
Commission or its staff with respect to the Registration Statement and permit
each holder of Registrable Securities and underwriters to do such investigation,
upon reasonable advance notice, with respect to information contained in or
omitted from the Registration Statement as it deems reasonably necessary to
comply with applicable securities laws or rules of the National Association of
Securities Dealers, Inc.  Such investigation shall include access to books,
records and properties and opportunities to discuss the business of the Company
with its officers and independent auditors, all to such reasonable extent and at
such reasonable times and as often as any such holder of Registrable Securities
or underwriter shall reasonably request.

          (j) Upon the written request therefor by any holders of Registrable
Securities, the Company shall include in the Registration Statement filed for an
underwritten offering covering any such holders Registrable Securities, any
additional shares of Common Stock of the Company, or,  with the approval of the
managing underwriter, any additional securities, held by such holders as of the
date of filing of such Registration Statement.  The holders shall pay any
additional costs, fees and expenses associated with the inclusion on such
Registration Statement of any of such holders shares of Common Stock or other
securities that are not Registerable Securities that are included on the
Registration Statement.  Notwithstanding the foregoing, if any such managing
underwriter shall advise the Company in writing that, in its opinion, the
distribution of all or a portion of the Common Stock that are not Registrable
Securities requested to be included in the Registration Statement concurrently
with the Registrable Securities being registered by such holders would
materially adversely affect the distribution of such offering then such
additional shares of Common Stock shall be excluded from the Registration
Statement.
<PAGE>

          (k) Upon the written request therefor by any holders of Registrable
Securities, the Company shall include in the Registration Statement filed for a
non-underwritten offering covering any of the Registrable Securities, any other
securities of the Company held by such holders as of the date of filing of such
Registration Statement, including, without limitation, restricted shares of
Common Stock, options, warrants or any other securities convertible into shares
of Common Stock.  The holders shall pay any additional costs, fees and expenses
associated with the inclusion on such Registration Statement of any of such
holders other securities of the Company that are not Registerable Securities
that are included on the Registration Statement.

     7.  ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF SECURITIES.  The following
adjustments apply to the Exercise Price of the Warrants with respect to the
Shares and the number of Shares purchasable upon exercise of the Warrants.

     7.1  COMPUTATION OF ADJUSTED PRICE.  In case the Company shall at any time
after the date hereof pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to its stockholders, then upon such
dividend or distribution the Exercise Price in effect immediately prior to such
dividend or distribution shall forthwith be reduced to a price determined by
dividing:

          (a) an amount equal to the total number of shares of Common Stock
outstanding immediately prior to such dividend or distribution multiplied by the
Exercise Price in effect immediately prior to such dividend or distribution, by

          (b) the total number of shares of Common Stock outstanding immediately
after such issuance or sale.

          For the purposes of any computation to be made in accordance with the
provisions of this Section 7.1, the shares of Common Stock issuable by way of a
dividend or other distribution on any shares of Common Stock of the Company
shall be deemed to have been issued immediately after the opening of business on
the date following the date fixed for the determination of stockholders entitled
to receive such dividend or other distribution.

     7.2  SUBDIVISION AND COMBINATION.  In case the Company shall at any time
subdivide or combine the outstanding shares of Common Stock, the Exercise Price
shall forthwith be proportionately decreased in the case of a subdivision or
increased in the case of a combination.

     7.3  ADJUSTMENT IN NUMBER OF SECURITIES.  Upon each adjustment of the
Exercise Price pursuant to the provisions of this Article 7, the number of
Shares issuable upon the exercise of each Warrant shall be adjusted to the
nearest full Share by multiplying a number equal to the Exercise Price in effect
immediately prior to such adjustment by the number of Shares issuable upon
exercise of the Warrants immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.
<PAGE>

     7.4  RECLASSIFICATION, CONSOLIDATION, MERGER, ETC.  In case of any
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination), or in the case of any consolidation
of the Company with, or merger of the Company into, another corporation (other
than a consolidation or merger in which the Company is the surviving corporation
and which does not result in any reclassification or change of the outstanding
shares of Common Stock, except a change as a result of a subdivision or
combination of such shares or a change in par value, as aforesaid), or in the
case of a sale or conveyance to another corporation of the property of the
Company as an entirety, the Holders shall thereafter have the right to purchase
the kind and number of shares of stock and other securities and property
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance as if the Holders were the owners of the Shares immediately prior to
any such events and at an aggregate price equal to the product of (x) the number
of shares of Common Stock issuable upon exercise of the Holders' Warrants and
(y) the Exercise Price in effect immediately prior to the record date for such
reclassification, change, consolidation, merger, sale or conveyance as if such
Holders had exercised the Warrants.

     7.5  DETERMINATION OF OUTSTANDING COMMON STOCK.  The number of shares of
Common Stock at any one time outstanding shall include the aggregate number of
shares issued or issuable upon the exercise of options, rights, warrants and
upon the conversion or exchange of convertible or exchangeable securities.

     7.6  SUBSCRIPTION RIGHTS FOR COMMON STOCK OR OTHER SECURITIES.  In the case
that the Company or an affiliate of the Company shall at any time after the date
hereof and prior to the exercise of all of the Warrants issue any rights to
subscribe for shares of Common Stock or any other securities of the Company or
of such affiliate to all of the shareholders of the Company, the Holders of the
unexercised Warrants shall be entitled, in addition to the shares of Common
Stock or other securities receivable upon the exercise of the Warrants, to
receive at the time such rights as are distributed to the other shareholders of
the Company.

     8.  EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.

     Each Warrant Certificate is exchangeable without expense, upon the
surrender hereof by the registered Holder at the principal executive office of
the Company, for a new Warrant Certificate of like tenor and date representing
in the aggregate the right to purchase the same number of Shares in such
denominations as shall be designated by the Holder thereof at the time of such
surrender.

     Upon receipt by the Company of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of any Warrant Certificate, and, in
case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.
<PAGE>

     9.  ELIMINATION OF FRACTIONAL INTERESTS.

     The Company shall not be required to issue certificates representing
fractions of Shares upon the exercise of the Warrants nor shall it be required
to issue scrip or pay cash in lieu of fractional interests, it being the intent
of the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest whole number of Shares.

     10.  RESERVATION AND LISTING OF SECURITIES.

     The Company shall at all times reserve and keep available out of its
authorized Common Stock, solely for the purpose of issuance upon the exercise of
the Warrants, such number of shares of Common Stock as shall be issuable upon
the exercise thereof.  The Company covenants and agrees that, upon exercise of
the Warrants and payment of the Exercise Price therefor, all Shares issuable
upon such exercise shall be duly and validly issued, fully paid, non-assessable
and not subject to the preemptive rights of any shareholder.  As long as the
Warrants shall be outstanding, the Company shall use its best efforts to cause
all shares of Common Stock issuable upon the exercise of the Warrants to be
listed on or quoted by the Nasdaq National Market, or listed on such national
securities exchanges as requested by the Underwriter.

     11.  NOTICES TO WARRANT HOLDERS.

     Nothing contained in this Agreement shall be construed as conferring upon
the Holder or Holders the right to vote or to consent or to receive notice as a
stockholder in respect of any meetings of stockholders for the election of
directors or any other matter, or as having any rights whatsoever as a
stockholder of the Company.  If, however, at any time prior to the expiration of
the Warrants and their exercise, any of the following events shall occur:

          (a) the Company shall take a record of all of the holders of its
     shares of Common Stock for the purpose of entitling them to receive a
     dividend or distribution payable otherwise than in cash, or a cash dividend
     or distribution payable otherwise than out of current or retained earnings,
     as indicated by the accounting treatment of such dividend or distribution
     on the books of the Company; or

          (b) the Company shall offer to all of the holders of its shares of
     Common Stock any additional shares of capital stock of the Company or
     securities convertible into or exchangeable for shares of capital stock of
     the Company, or any option, right or warrant to subscribe therefor; or

          (c) a dissolution, liquidation or winding up of the Company (other
     than in connection with a consolidation or merger) or a sale of all or
     substantially all of its property, assets and business as an entirety shall
     be proposed; or
<PAGE>

          (d) reclassification or change of the outstanding shares of Common
     Stock (other than a change in par value to no par value, or from no par
     value to par value, or as a result of a subdivision or combination),
     consolidation of the Company with, or merger of the Company into, another
     corporation (other than a consolidation or merger in which the Company is
     the surviving corporation and which does not result in any reclassification
     or change of the shares of outstanding Common Stock, except a change as a
     result of a subdivision or combination of such shares or a change in par
     value, as aforesaid), or a sale or conveyance to another corporation of the
     property of the Company as an entirety is proposed; or

          (e) the Company or an affiliate of the Company shall propose to issue
     any rights to subscribe for shares of Common Stock or any other securities
     of the Company or of such affiliate to all the stockholders of the Company;

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
shareholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, options or warrants, or entitled
to vote on such proposed dissolution, liquidation, winding up or sale.  Such
notice shall specify such record date or the date of closing the transfer books,
as the case may be.  Failure to give such notice or any defect therein shall not
affect the validity of any action taken in connection with the declaration or
payment of any such dividend or distribution, or the issuance of any convertible
or exchangeable securities or subscription rights, options or warrants, or any
proposed dissolution, liquidation, winding up or sale.

     12.  NOTICES.

     All of notices, requests, consents and other communications hereunder shall
be in writing and shall be deemed to have been duly made when delivered, or
mailed by registered or certified mail, return receipt requested:

          (a)  If to a registered Holder of the Warrants, to the address of such
     Holder as shown on the books of the Company; or

          (b)  If to the Company, to the address set forth in Section 3 of this
     Agreement or to such other address as the Company may designate by notice

EXERCISABLE ON OR BEFORE 5:00 P.M., WASHINGTON, D.C. TIME, November 25, 2007


No. W-2                                                    1,950,000 Warrants

                                 WARRANT CERTIFICATE

     This Warrant Certificate certifies that Jonathan J. Ledecky or registered
assigns, is the registered holder of 1,950,000 Warrants to purchase, at any time
from November 25, 1997 until 5:00 p.m. Washington, D.C. time on November 25,
2007 ("Expiration Date"), 1,950,000 fully paid and non-assessable shares
("Shares") of the Common Stock, par value $.001 per share ("Common Stock"), of
Consolidation Capital Corporation, a Delaware corporation (the "Company"), at
the initial exercise price, subject to adjustment in certain events (the
"Exercise Price"), of $20.00 per Share, upon surrender of this Warrant
Certificate and payment of the Exercise Price at an office or agency of the
Company, but subject to the conditions set forth herein and in the warrant
agreement dated as of November 25, 1997 between the Company and Jonathan J.
Ledecky (the "Warrant Agreement").  Payment of the Exercise Price may be made in
cash, or by check payable to the order of the Company, or any combination of
cash or check.

     No Warrant may be exercised after 5:00 p.m., Washington, D.C. time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter be void.

     The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to in a description of the rights, limitation
of rights, obligations, duties and immunities thereunder of the
<PAGE>

Company and the holders (the words "holders" or "holder" meaning the registered
holders or registered holder) of the Warrants.

     The Warrant Agreement provides that upon the occurrence of certain events,
the Exercise Price and/or number of the Company's securities issuable thereupon
may, subject to certain conditions, be adjusted.  In such event, the Company
will, at the request of the holder, issue a new Warrant Certificate evidencing
the adjustment in the Exercise Price and the number and/or type of securities
issuable upon the exercise of the Warrants; provided, however, that the failure
of the Company to issue such new Warrant Certificates shall not in any way
change, alter, or otherwise impair, the rights of the holder as set forth in the
Warrant Agreement.

     Upon due presentment for registration of transfer of this Warrant
Certificate at an office or agency of the Company, a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided herein and in the Warrant
Agreement, without any charge except for any tax, or other governmental charge
imposed in connection therewith.

     Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

     The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

     All terms used in this Warrant Certificate which are defined in the Warrant
Agreement shall have the meanings assigned to them in the Warrant Agreement.

     IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to be
duly executed under its corporate seal.
