                                   THE MERGER

     1.1    The Merger. At the Effective Time (as defined in Section 1.2(a))
and subject to and upon the terms and conditions of this Agreement and the
applicable provisions of Delaware Law, the Subsidiary shall be merged with and
into the Company (the "Merger"), the separate corporate existence of the
Subsidiary shall cease, and the Company shall continue as the surviving
corporation. The Company as the surviving corporation after the Merger is
hereinafter sometimes referred to as the "Surviving Corporation."

     1.2    Effective Time; Closing.
            -----------------------

            (a)    As promptly as practicable after the Closing (as defined in
Section 1.2(b)), the parties hereto shall cause the Merger to be consummated by
filing a certificate of merger with the Secretary of State of the State of
Delaware, in such form as required by, and executed in accordance with the
relevant provisions of, Delaware Law (the "Certificate of Merger"). When used in
this Agreement, the term "Effective Time" shall mean the date and time at which
the Merger shall become effective under Delaware Law.

            (b)    The closing of the transactions contemplated by this
Agreement (the "Closing") shall be held at the offices of Proskauer Rose LLP,
1585 Broadway, New York, New York 10036, on the date hereof, or at another time
and date to be specified by the parties, which shall be no later than the second
business day after the satisfaction or waiver, as the case may be, of the
conditions set forth in Article VI, or at such other time, date and location as
the parties hereto agree in writing (the "Closing Date").

     1.3    Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in this Agreement and the applicable provisions of
Delaware Law. Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time all the rights, privileges, powers, franchises
and property of the Subsidiary and the Company shall vest in the Surviving
Corporation, and all restrictions, disabilities, duties, debts and liabilities
of the Subsidiary and the Company shall become the restrictions, disabilities,
duties, debts and liabilities of the Surviving Corporation.

     1.4    Certificate of Incorporation; By-Laws.
            -------------------------------------

            (a)    At the Effective Time, the Certificate of Incorporation of
the Subsidiary, as in effect immediately prior to the Effective Time, shall be
the Certificate of Incorporation of the Surviving Corporation, and shall
continue in full force and effect until thereafter amended; provided, however,
that at the Effective Time Article I of the Certificate of Incorporation of the
Surviving Corporation shall be amended to read: "The name of the corporation is
Sabela Media, Inc."

                                       3



            (b)    At the Effective Time, the Bylaws of the Subsidiary, as in
effect immediately prior to the Effective Time, shall be the bylaws of the
Surviving Corporation until thereafter amended.

     1.5    Directors and Officers. The directors and officers of the
Subsidiary shall be the directors and officers of the Surviving Corporation, in
each case until their respective successors are duly elected or appointed and
qualified.

     1.6    Effect on Capital Stock. At the Effective Time, by virtue of the
Merger and without any action on the part of the Subsidiary, the Company or the
holders of any of the following securities:

            (a)    Conversion of Company Common Stock. Each share of common
stock, par value $0.001 per share, of the Company ("Company Common Stock")
issued and outstanding immediately prior to the Effective Time, other than any
shares of Company Common Stock to be canceled pursuant to Section 1.6(c), will
be canceled and extinguished and automatically converted (subject to Sections
1.6(e) and (f)) into the right to receive (the "Exchange Ratio") (i) 0.1104 of a
share of validly issued, fully paid and nonassessable common stock, par value
$0.01 per share, of 24/7 (the "24/7 Common Stock"), and (ii) U.S. $0.2051, upon
surrender of the certificates representing such shares of Company Common Stock.

            (b)    (i)    The Company's obligations with respect to each
outstanding option, as set forth on Schedule 1.6(b) hereto (the "Assumed
Options") other than those options designated on such schedule as "non-assumed
options" (the "Non-assumed Options"), to purchase shares of common stock of the
Company issued pursuant to the Company's 1999 Stock Option/Stock Issuance Plan
(the "Company Option Plan"), whether vested or unvested, shall, by virtue of
this Agreement and without any further action of the Company, 24/7 or the holder
of any Assumed Option, be assumed by 24/7 under its 1998 Stock Incentive Plan.
Unless otherwise elected by 24/7 prior to the Effective Time, 24/7 shall make
such assumption in such manner that (i) 24/7 is a corporation "assuming a stock
option in a transaction to which Section 424(a) applies" within the meaning of
Section 424 of the Code or (ii) to the extent that Section 424 of the Code does
not apply to such Assumed Option, 24/7 would be such a corporation were Section
424 of the Code applicable to such Assumed Option; and, if not so otherwise
elected, after the Effective Time, all references to the Company Option Plan
shall be deemed to refer to 24/7's 1998 Stock Incentive Plan as of the Effective
Time by virtue of this Agreement and without any further action. In connection
therewith, the Company shall, and hereby does, assign to 24/7 effective at the
Closing any and all "repurchase rights" of the Company with respect to the
Assumed Options and Option Shares. "Option Shares" means shares of Company
Common Stock purchased upon exercise of options under the Company Option Plan
prior to vesting of such options.

                   (ii)   Each Assumed Option so assumed by 24/7 under this
Agreement shall continue to have, and be subject to, similar terms and
conditions set forth in the Company Option Plan as in effect immediately prior 
to the Effective Time, except that (i) such 


                                       4





Assumed Option shall be governed by 24/7's 1998 Stock Incentive Plan, (ii) such
Assumed Option will be exercisable for that number of shares of 24/7 Common
Stock equal to the product of the number of shares of common stock of the
Company that were purchasable under such Assumed Option immediately prior to the
Effective Time multiplied by 0.1146 (the "Option Ratio"), rounded to the nearest
whole number of shares of 24/7 Common Stock, and (iii) the per share exercise
price for the shares of 24/7 Common Stock issuable upon exercise of such Assumed
Option will be equal to the exercise price per share of common stock of the
Company at which such Assumed Option was exercisable immediately prior to the
Effective Time divided by the Option Ratio, and rounding the resulting exercise
price up to the nearest whole cent.

                   (iii)  As soon as reasonably practicable after the Effective 
Time, the Company will deliver to Assumed Option holders appropriate notices
setting forth such holders' rights pursuant to 24/7's 1998 Stock Incentive Plan
and confirming that the Assumed Options have been assumed by 24/7 under its 1998
Stock Incentive Plan in accordance with the terms and conditions required by
this Section 1.6(b).

                   (iv)   24/7 shall not assume any obligations of the Company 
with respect to the Non-assumed Options. Each holder of Non-assumed Options
shall be given the opportunity to exercise such Non-assumed Option effective
immediately prior to the Effective Time.

            (c)    Cancellation of Company-Owned Stock. Each share of Company
Common Stock held by the Company immediately prior to the Effective Time shall
be canceled and extinguished without any conversion thereof.

            (d)    Capital Stock of the Subsidiary. Each share of common stock, 
par value $0.01 per share, of the Subsidiary issued and outstanding immediately
prior to the Effective Time shall be exchanged for and converted into one
validly issued, fully paid and non-assessable share of common stock, par value
$0.01 per share, of the Surviving Corporation. Each stock certificate of the
Subsidiary evidencing ownership of any such shares shall evidence ownership of
such shares of capital stock of the Surviving Corporation.

            (e)    Fractional Shares.  No fraction of a share of 24/7 Common 
Stock shall be issued by virtue of the Merger, but in lieu thereof each holder
of a share of Company Common Stock who would otherwise be entitled to a fraction
of a share of 24/7 Common Stock (after aggregating all fractional shares of 24/7
Common Stock that otherwise would be received by such holder) shall receive from
24/7 an amount of cash (rounded to the nearest whole cent) equal to the product
of (i) such fraction, multiplied by (ii) the average closing price of one share
of 24/7 Common Stock for the ten (10) most recent days that 24/7 Common Stock
has traded ending on the trading day immediately prior to the Effective Time, as
reported on the Nasdaq National Market System ("Nasdaq").

            (f)    Adjustments to Exchange Ratio.  The Exchange Ratio shall be 
adjusted to reflect fully the appropriate effect of any stock split, reverse 
stock split, stock 

                                       5



dividend (including any dividend or distribution of securities convertible into
24/7 Common Stock), reorganization, recapitalization, reclassification or other
like change with respect to 24/7 Common Stock occurring on or after the date
hereof and prior to the Effective Time.

            (g)    All Other Capital Stock of the Company.  All other capital 
stock of the Company shall be canceled and retired and shall cease to exist, and
no consideration shall be issued or delivered in exchange therefor.

     1.7    Surrender and Payment.
            ---------------------

            (a)    The Merger Consideration delivered upon the surrender for 
exchange of the shares of Company Common Stock in accordance with the terms
hereof shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares, and after the Effective Time, there shall be no
further registration or transfers of shares of Company Common Stock outstanding
prior to the Closing Date. If after the Effective Time certificates which
immediately prior to the Effective Time represented outstanding shares of
Company Common Stock (the "Certificates") are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Article I.

            (b)    If certificates for shares of 24/7 Common Stock are to be 
issued in the name of a person other than the person in whose name the
surrendered Certificate is registered, it shall be a condition of the issuance
thereof that the Certificates so surrendered shall be properly endorsed or shall
be otherwise in proper form for transfer and that the person requesting such
exchange shall have paid to 24/7 or any agent designated by it any transfer or
other taxes required by reason of the issuance of certificates for shares of
24/7 Common Stock in the name of a person other than the registered holder of
the Certificate surrendered or shall have established to the satisfaction of
24/7 or any agent designated by it that such tax either has been paid or is not
applicable.

     1.8    Escrow Indemnity Account. Promptly after the Closing Date, 24/7 
shall deliver to the escrow agent (the "Escrow Agent") under the escrow
agreement dated the Closing Date, substantially in the form of Exhibit A hereto
(the "Escrow Indemnity Agreement"), a certificate representing 312,588 shares of
24/7 Common Stock otherwise deliverable to the Stockholders, to be held pursuant
to the provisions of the Escrow Indemnity Agreement to be held in an escrow
account (the "Escrow Indemnity Account") pursuant to the terms of the Escrow
Indemnity Agreement.

     1.9    Dissenters' Rights. The holders of shares of Company Common Stock as
to which dissenters' rights shall have been duly demanded under applicable law
("Dissenting Shares"), if any, shall be entitled to payment by the Surviving
Corporation only of the fair value of such shares plus accrued interest to the
extent permitted by and in accordance with the provisions of applicable law;
provided, however, that (i) if any holder of the Dissenting Shares shall, under
the circumstances permitted by applicable law, subsequently deliver a written
withdrawal of such holder's demand or (ii) if any holder fails to establish such
holder's 

                                       6




entitlement to rights to payment as provided under applicable law, such holder
or holders (as the case may be) shall forfeit such right to payment for such
shares and such shares shall thereupon be deemed to have been converted into
24/7 Common Stock as of the Effective Time.

     1.10   Lost, Stolen or Destroyed Certificates. If any Certificates shall
have been lost, stolen or destroyed, 24/7 shall issue in exchange for such lost,
stolen or destroyed Certificates, upon the making of an affidavit of that fact
by the holder thereof, the Merger Consideration; provided, however, that 24/7
may, in its discretion and as a condition precedent to the issuance and delivery
thereof, require the owner of such lost, stolen or destroyed Certificates to
deliver a bond in such sum as it may reasonably direct as indemnity against any
claim that may be made against 24/7 or the Company with respect to the
Certificates alleged to have been lost, stolen or destroyed.

     1.11   Taking of Necessary Action; Further Action. If, at any time after 
the Effective Time, any such further action is necessary or desirable to carry
out the purposes of this Agreement and to vest the Surviving Corporation with
full right, title and possession to all assets, property, rights, privileges,
powers and franchises of the Company and the Subsidiary, the officers and
directors of the Company and the Subsidiary are fully authorized in the name of
their respective corporations or otherwise to take, and will take, all such
lawful and necessary action. 24/7 shall cause the Subsidiary to perform all of
its obligations relating to this Agreement and the transactions contemplated
hereby.


                                   ARTICLE II
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as disclosed in that section of the document of even date herewith
delivered by the Company to 24/7 prior to the execution and delivery of this
Agreement (the "Company Disclosure Schedule") corresponding to the section of
this Agreement to which any of the representations and warranties specifically
relate or as disclosed in another section of the Company Disclosure Schedule if
it is reasonably apparent on the face of the disclosure that it is applicable to
another section of this Agreement, the Company and the Stockholder represent and
warrant to 24/7 as follows:

incorporation and has the requisite power and authority to own, lease and
operate the properties it purports to own, operate or lease and to carry on its
business as it is now being conducted and as currently proposed to be conducted,
except where the failure to be so organized, existing and in good standing or to
have such power and authority would not reasonably be expected to have a
material adverse effect on the business, results of operations or financial
condition of the Company, taken as a whole, or on the ability of the parties to
consummate the transactions contemplated by this Agreement ("Company Material
Adverse Effect"). The Company and each of its subsidiaries is duly qualified or

standing, in each jurisdiction where the character of its properties owned,
leased or operated by it or the nature of its activities makes such
qualification or licensing necessary, except for such failures to be so duly
qualified or licensed and in good standing that would not reasonably be expected
to have a Company Material Adverse Effect. A true and complete list of all of
the Company's subsidiaries, together with the jurisdiction of incorporation of
each subsidiary and the percentage of each subsidiary's outstanding capital
stock owned by the Company or another subsidiary, is set forth in Section 2.1 of

furnished to 24/7 a complete and correct copy of its Certificate of

Hazardous Substances in, on, over, under or at it, in concentrations which would
violate in any material respect any applicable Environmental Laws or reasonably
would be likely to result in the imposition of material liability or obligations
on the Company or any of its subsidiaries under any applicable Environmental
Laws, including any material liability or obligations for the investigation,
corrective action, remediation or monitoring of Hazardous Substances in, on,
over, under or at the Real Property. Neither the Company nor any of its

necessary for the conduct of their businesses and for the operations on, in or
at the Real Property which are required under applicable Environmental Laws (the
"Environmental Permits") and they are in compliance in all material respects

2000, policies of insurance and bonds of the type and in amounts customarily
carried by persons conducting businesses or owning assets similar to those of
the Company and its subsidiaries. There is no material claim pending under any
of such policies or bonds as to which coverage had been questioned, denied or
disputed by the underwriters of such policies or bonds. All premiums due and
payable under all such policies and bonds have been paid and the Company and its
subsidiaries are otherwise in compliance with the terms of such policies and
bonds. The Company has no knowledge of any threatened termination of, or
material premium increase with respect to, any such policies.

the Company and its subsidiaries, and reflect all transactions referred to in
such minutes accurately in all material respects.

     2.23 Improper Payments. The Company and its officers and agents have not

benefit or 


                                       21

                                   ARTICLE III
            REPRESENTATIONS AND WARRANTIES OF 24/7 AND THE SUBSIDIARY

     24/7 and the Subsidiary hereby represent and warrant to the Company subject
to the exceptions specifically disclosed in writing in the disclosure letter
delivered by 24/7 to the Company dated as of the date hereof and certified by a
duly authorized officer of 24/7 (the "24/7 Disclosure Schedule"), as follows:

     3.1    Organization and Qualification; Organizational Documents.
            --------------------------------------------------------

            (a)    Each of 24/7 and the Subsidiary is a corporation duly 
organized, validly existing and in good standing under the laws of the State of
Delaware and has the requisite power and authority to own, lease and operate the
properties it purports to own, operate or lease and to carry on its business as
it is now being conducted, except where the failure to be so organized, existing
and in good standing or to have such power and authority would not reasonably be
expected to have a material adverse effect on the business, results of
operations or financial condition of 24/7, taken as a whole, or on the ability
of the parties to consummate the transactions contemplated by this Agreement
("24/7 Material Adverse Effect"). Each of 24/7 and the Subsidiary is duly
qualified or licensed as a foreign corporation to do business, and is in good
standing, in each jurisdiction where the character of its properties owned,
leased or operated by it or the nature of its activities makes such
qualification or licensing necessary, except for such failures to be so duly
qualified or licensed and in good standing that would not reasonably be expected
to have a 24/7 Material Adverse Effect.

            (b)    24/7 has made available to the Company a complete and correct
copy of 24/7's and the Subsidiary's Certificate of Incorporation (certified by
the Secretary of State of the State of Delaware) and By-Laws, each as amended to
date. Such Certificates of Incorporation and By-Laws are in full force and
effect. Neither 24/7 nor the Subsidiary is in violation of any of the provisions
of its respective Certificate of Incorporation or By-Laws.

or any of its subsidiaries before any Governmental Entity that seek to restrain
or enjoin the consummation of the transactions contemplated by this Agreement.

warranty is made as of a specified date, in which case such representation or
warranty shall have been true and correct in all material respects as of such
date.

     6.2    Performance by the Company. The Company shall have performed and
complied in all material respects with all agreements, covenants and conditions
required by the Company Documents to be performed or complied with by the

                                    ARTICLE X

                 FURTHER PROVISIONS REGARDING INDEMNIFICATION

     10.1   Survival. All representations and warranties made by the Company or 
the Stockholders in the Company Documents or by 24/7 or the Subsidiary in this
Agreement shall survive the Closing until April 30, 2001, notwithstanding any
examination or investigation made by or for any party.


                                       35




     10.2   Limitations.  Notwithstanding the foregoing,

            (a)    The indemnification in Sections 9.1 and 9.2, as the case
may be, shall be the exclusive remedy of the Stockholders, Sabela and of 24/7
and its affiliates with respect to claims for Losses;

            (b)    The indemnification provided for in Section 9.1(i) or 9.2(i) 
above shall not be required unless and until, at the time of any such
determination, the total amount of Losses otherwise subject to indemnification
under such section exceeds $500,000, in which event the indemnified party or
parties will be entitled to indemnification for the full amount of their Losses;

            (c)    The total amount of indemnification provided by the
Stockholders pursuant to Section 9.1(i) shall in no event exceed an aggregate
amount equal to $15,100,000;

            (d)    Neither any Stockholder of the Company, on the one hand,
nor 24/7 or any of its affiliates, on the other, shall be entitled to
indemnification for Losses arising out of matters referred to in Section 9.1(i)
or 9.2(i), as applicable, unless it shall have given written notice to the
indemnifying party, setting forth its claim for indemnification in reasonable
detail, within the period from the Closing Date until April 30, 2001;

            (e)    An indemnified party shall promptly give written notice to
the indemnifying party after the indemnified party has knowledge that any legal
proceeding has been instituted or any claim has been asserted in respect of
which indemnification may be sought under the provisions of Sections 9.1 or 9.2.
If the indemnifying party, within 30 days after the indemnified party has given
such notice (or within such shorter period of time as an answer or other
responsive motion may be required), shall have acknowledged in writing his or
its obligation to indemnify, then the indemnifying party shall have the right to
control the defense of such claim or proceeding, and the indemnifying party
shall not settle or compromise such claim or proceeding without the written
consent of the indemnified party. The indemnified party may in any event 
participate in any such defense with his or its own counsel and at his or its 
own expense; and

            (f)    The indemnified party shall be kept fully informed by the
indemnifying party of such action, suit or proceeding at all stages thereof,
whether or not he or it is represented by counsel. The indemnifying party shall,
at the indemnifying party's expense, make available to the indemnified party and
its attorneys and accountants all books and records of the indemnifying party
relating to such action, suit or proceeding, and the parties hereto agree to
render to each other such assistance as they may reasonably require of each
other in order to ensure the proper and adequate defense of any such action,
suit or proceeding.

     10.3   Exclusive Remedy. In accordance with the provisions of the Escrow 
Indemnity Agreement, 24/7 shall be entitled, from time to time, to receive from
the Escrow Agent the number of shares of 24/7 Common Stock having a value equal
to the Losses of 24/7 as 



                                       36





to which 24/7 is entitled to be indemnified pursuant to 9.1 above, subject to
the provisions of Section 10.2(c). For purposes of this Section 10.3 and the
Escrow Agreement, the value of 24/7 Common Stock to be delivered to cover Losses
shall be the average of the closing prices of the 24/7 Common Stock on the five
trading days preceding the delivery of the shares to 24/7 in accordance with the
provisions of the Escrow Agreement. The right to receive such shares in
accordance with the provisions of this Article X shall be 24/7's sole remedy for
Losses that it is entitled to recover under Section 9.1.

     10.4   Delivery of Notice. 24/7 shall deliver such written notices to such 
parties and at such times as required by the provisions of the Escrow Agreement,
and the releases of shares provided for in Sections 9.1 or 9.3 shall be governed
by the provisions of the Escrow Agreement. 24/7 and the Company agree to
promptly deliver a written notice to the Stockholders upon any determination
that a claim for Losses under Section 9.1 or 9.2 is reasonably likely to exist.

     10.5   Indemnification of Directors and Officers of the Company. 24/7
(A) will not take or knowingly permit to be taken any action to alter or impair
any exculpatory or indemnification provisions now existing in the Charter or
Bylaws of the Company for the benefit of any individual who served as officer of
the Company at any time prior to the Effective Time, and (B) shall cause the
Surviving Corporation to honor and fulfill such provisions until the date which
is two years from the Effective Time; provided, however, in the event any claim
is commenced within such two-year period, such indemnification provisions shall
continue in effect until the final disposition thereof.
