                                MERGER AGREEMENT

     This MERGER AGREEMENT (this "Agreement") is made and entered into March
8, 2000 among Software.com, Inc., a Delaware corporation ("Parent"),
Software.com Wireless, Inc., a Delaware corporation and a wholly-owned
subsidiary of Parent ("Merger Sub") and At Mobile.com, Inc., a Delaware
corporation (the "Company" and, together with Parent and Merger Sub,
individually a "Party" and collectively the "Parties").

                                    RECITALS

     A.      The Board of Directors of each Party believes it is in the best
interests of each respective company and its stockholders that Parent acquire
the Company through the statutory merger of the Merger Sub with and into the
Company (the "Merger") and, in furtherance thereof, have approved the Merger.

     B.      Pursuant to the Merger, among other things, and subject to the
terms and conditions of this Agreement, all of the issued and outstanding shares
of the Company's (i) common stock (the "Company Common Stock"), (ii) Series A
Preferred Stock (the "Series A Preferred Stock"), (iii) Series B Preferred Stock
(the "Series B Preferred Stock"), (iv) Series C Preferred Stock (the "Series C
Preferred Stock") and (v) Series D Preferred Stock (the "Series D Preferred
Stock") and collectively with the Series A Preferred Stock, the Series B
Preferred and the Series C Preferred Stock, the "Company Preferred Stock" and,
together with the Company Common Stock, the "Company Stock"), each having a par
value of $0.001 per share shall be converted into the right to receive shares of
the common stock, par value $0.001 per share, of Parent ("Parent Common Stock").

     C.      A portion of the shares of Parent Common Stock otherwise issuable
by Parent in the Merger shall be placed in escrow by Parent, the release of
which amount shall be contingent upon certain events and conditions.

     D.      The Company, Parent and Merger Sub desire to make certain
representations and warranties and other agreements in connection with the
Merger.

     E.      For federal income tax purposes, the Parties intend to adopt a plan
or reorganization within the meaning of, and to cause the Merger to qualify as a
reorganization under, Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code").

     F.      For financial accounting purposes, the Parties intend that the
transactions under this Agreement (the "Transactions") will be accounted for as
a "pooling of interests" (a "Pooling Transaction") under United States generally
accepted accounting principles ("GAAP") and the rules, regulations and
interpretations of the Securities and Exchange Commission (the "SEC").
<PAGE>

     NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby, the parties agree as follows:

                                   ARTICLE I


                                   THE MERGER

     1.1     The Merger.  At the Effective Time and pursuant to this Agreement
             ----------
and the applicable provisions of the Delaware General Corporation Law (the
"Delaware Law"), Merger Sub shall be merged with and into the Company, the
separate corporate existence of Merger Sub shall cease and the Company shall
continue as the surviving corporation and as a wholly-owned subsidiary of
Parent.  The Company as the surviving corporation after the Merger is sometimes
referred to as the "Surviving Corporation."

     1.2     Effective Time.  Unless this Agreement is earlier terminated
             --------------
pursuant to Section 7.1, the closing of the Merger (the "Closing") will take
            -----------
place as promptly as practicable, but no later than two business days following
satisfaction or waiver of the conditions set forth in Article V, at the offices
                                                      ---------
of Parent, 525 Anacapa Street, Santa Barbara, California 93101, unless another
place or time is agreed to by Parent and the Company.  The date upon which the
Closing actually occurs is referred to as the "Closing Date."  On the Closing
Date, the Parties shall cause the Merger to be consummated by filing a
Certificate of Merger with the Secretary of State of Delaware (the "Certificate
of Merger").  The date and time the Merger becomes effective in accordance with
the Delaware Law is referred to as the "Effective Date" or "Effective Time."

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

     1.4    Certificate of Incorporation; Bylaws.
            ------------------------------------

            (a)  Unless otherwise determined by Parent prior to the Effective
Time, at the Effective Time, the Certificate of Incorporation of the Merger Sub
shall be the Certificate of Incorporation of the Surviving Corporation until
thereafter amended as provided by law and such Certificate of Incorporation;
provided, however, that Article I of the Certificate of Incorporation of the
Surviving Corporation shall be amended to read as follows: "The name of the
corporation is At Mobile.com, Inc."

            (b)  The Bylaws of the Merger Sub, as in effect immediately prior to
the Effective Time, shall be the Bylaws of the Surviving Corporation until
thereafter amended.

                                      -2-
<PAGE>

     1.5    Directors and Officers. The director(s) of Merger Sub immediately
            ----------------------
prior to the Effective Time shall be the initial director(s) of the Surviving
Corporation, each to hold office in accordance with the Surviving Corporation's
Certificate of Incorporation and Bylaws. The Merger Sub's officers immediately
prior to the Effective Time shall be the initial officers of the Surviving
Corporation, each to hold office in accordance with the Bylaws of the Surviving
Corporation.

     1.6    Effect on Capital Stock. At the Effective Time, by virtue of the
            -----------------------
Merger and without any action on the part of Merger Sub or the Company or any of
their respective stockholders:

            (a)   Cancellation of Parent-Owned and Company-Owned Stock. Each
                  ----------------------------------------------------
share of Company Common Stock and Company Preferred Stock owned by Merger Sub,
Parent, the Company or any direct or indirect wholly-owned subsidiary of Parent
or of the Company immediately prior to the Effective Time (the "Excluded Company
Shares") shall be canceled and extinguished without any conversion thereof.

            (b)   Common Stock of Merger Sub. Each share of common stock of
                  --------------------------
Merger Sub issued and outstanding immediately prior to the Effective Time shall
be converted into and exchanged for one validly issued, fully paid and
nonassessable share of the common stock of the Surviving Corporation. Each stock
certificate of Merger Sub evidencing ownership of any such shares shall from and
after the Effective Time evidence ownership of shares of capital stock of the
Surviving Corporation.

            (c)   Conversion of Company Stock. Subject to Section 1.10, each
                  ---------------------------             ------------
share of Company Stock issued and outstanding immediately prior to the Effective
Time (other than shares of Company Stock held by Dissenting Stockholders) shall
be converted into a fraction of a share of Parent Common Stock equal to the
Exchange Ratio (as defined in Section 1.6(e)). All such Company Stock, when so
                              --------------
converted, shall no longer be outstanding and shall automatically be canceled
and retired and shall cease to exist, and the holder of a certificate ("Stock
Certificate") that, immediately prior to the Effective Time, represented
outstanding shares of Company Stock shall cease to have any rights with respect
thereto, except the right to receive, upon the surrender of such Stock
Certificate, (i) the Parent Common Stock (the "Merger Consideration") to which
such holder is entitled pursuant to this Section 1.6(c), (ii) certain dividends
                                         --------------
and other distributions in with Section 1.6(d), and (iii) cash in lieu of
                                --------------
fractional shares Parent Common Stock in accordance with Section 1.10, without
                                                         ------------
interest. Until surrendered as contemplated by Section 1.7, each Stock
                                               -----------
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive upon such surrender the Merger Consideration as
contemplated by this Section 1.6(c). Notwithstanding the foregoing, if between

               ----------------------
Common Stock is to be issued in a name other than that in which the Stock
Certificate surrendered in exchange therefor is registered, it will be a

the Person requesting such exchange will have paid to Parent or any agent
designated by it any transfer or other taxes required because of the issuance of
a certificate for shares of Parent Common Stock in any name other than that of

     1.8  Stock Options.
          -------------

          (a)  Assumption of Options. At the Effective Time, automatically and
               ---------------------
without any action on the part of the holder thereof, each outstanding employee
or director stock option of the Company outstanding at the Effective Time (the
"Company Options") shall be assumed by Parent and become an option to purchase
that number of shares of Parent Common Stock obtained by multiplying the number
of shares of Company Common Stock issuable upon the exercise of such option by
the Exchange Ratio at an exercise price per share equal to the per share
exercise price of such option divided by the Exchange Ratio and otherwise upon
the same terms and conditions as such outstanding options to purchase Company
Common Stock, including to the extent such options were incentive stock options;
provided, however, that in the case of any option to which Section 421 of the
Code applies because of the qualifications under Sections 422 or 423 of the
Code, the exercise price, the number of shares purchasable pursuant to such
option and the terms and conditions of exercise of such option shall comply with
Section 424(a) of the Code.

          (b)  Reservation of Shares. Parent shall take all corporate actions
               ---------------------
necessary to reserve for issuance a sufficient number of shares of Parent Common
Stock for delivery upon exercise of Company Options assumed by Parent pursuant
to Section 1.8(a).
   --------------

          (c)  Form S-8. Within 30 days after Closing, Parent shall file a
               --------
registration statement on Form S-8 (or any successor or other appropriate forms)
with respect to the shares of Parent Common Stock subject to Company Options and
shall use all reasonable efforts to maintain the effectiveness of such
registration statement (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such options remain outstanding.

          (d)  Amendments to Plans. Each of the Company stock option plans
               -------------------
providing for the issuance or grant of options in respect to the stock of
Company shall be assumed as of the Effective Time by Parent with such amendments
thereto as may be required to reflect the Merger, including the substitution of
Parent Common Stock for Company Common Stock thereunder.

     1.9  Assumption of Warrants.
          ----------------------

          (a)  At the Effective Time, automatically and without any action on
the part of the holder thereof, Parent shall assume each Company Warrant
remaining outstanding following the Merger and it shall become a warrant to
purchase that number of shares of Parent Common Stock obtained by multiplying
the number of shares of Company Common Stock issuable upon the exercise of such
warrant by the Exchange Ratio at an exercise price per share equal to the per

                                      -6-
<PAGE>

share exercise price of such warrant divided by the Exchange Ratio and otherwise
upon the same terms and conditions as the applicable warrant.

           (b)  Parent shall take all corporate actions necessary to reserve for
issuance a sufficient number of shares of Parent Common Stock for delivery upon
exercise of Company Warrants assumed by Parent pursuant to Section 1.9(a).
                                                           --------------
     1.10  No Fractional Shares. No fractional shares of Parent Common Stock
           --------------------
shall be issued in the Merger and fractional share interests shall not entitle
the owner thereof to vote or to any rights of a stockholder of Parent. All
holders of fractional shares of Parent Common Stock shall be entitled to
receive, in lieu thereof, an amount in cash determined by multiplying the
fraction of a share of Parent Common Stock to which such holder would otherwise
have been entitled by the closing sale price of Parent Common Stock on the
trading day prior to the Effective Time.

     1.11  Tax Treatment. The Parties intend that the Merger shall constitute a
           --------------
tax free reorganization within the meaning of Section 368 of the Code.

     1.12  Accounting Treatment.  The Parties intend that the Merger will be
           --------------------
accounted for as a "pooling of interests" in accordance with GAAP and the rules,
regulations and interpretations of the SEC.

     1.13  Shares of Dissenting Stockholders. Any issued and outstanding shares
           ---------------------------------
of Company Common Stock a Dissenting Stockholder holds shall be converted into
the right to receive such consideration as may be determined to be due to such
Dissenting Stockholder pursuant to the Delaware Law; provided, however, shares
of Company Common Stock outstanding at the Effective Time and held by a
Dissenting Stockholder who shall, after the Effective Time, withdraw their
demand for purchase or lose their right of purchase as provided in the Delaware
Law, shall be deemed to be converted, as of the Effective Time, into the right
to receive the shares of Parent Common Stock, dividends and distribution, if
any, in accordance with Section 1.6(d), and cash in lieu of fractional shares in
                        --------------
accordance with Section 1.10, without interest. The Company shall give Parent
                ------------
(A) prompt notice of any written demands it receives for purchase, withdrawals
of demands for purchase and any other instruments served pursuant to Section 262
of the Delaware Law, and (B) the opportunity to direct all negotiations and
proceedings with respect to demands for purchase under Section 262 of the
Delaware Law. The Company will not voluntarily make any payment with respect to
any such demands for purchase and will not, except with the prior written
consent of Parent, settle or offer to settle any such demands.

     1.14  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 Merger Sub, the officers and directors of the
Company, Parent and Merger Sub are fully authorized in the name of their
respective corporations or otherwise to take, and the Company and Merger Sub
shall cause them to take, all such lawful and necessary action.

    6.2  Defense of Third Party Claims.
         -----------------------------

         (a)  An Indemnified Party shall give prompt written notice to any
Person who is obligated to provide indemnification under Section 6.1 (an
                                                         -----------
"Indemnifying Party") of the commencement or assertion of any action,
proceeding, demand or claim by a third party (collectively, a "Third Party
Action") in respect of which such Indemnified Party shall seek indemnification
hereunder; provided, however, that an Indemnified Party shall be deemed to have
given such notice to each of the Company's stockholders if such Indemnified
Party gives such notice to the Seller Representative. Any failure so to notify
an Indemnifying Party shall not relieve such Indemnifying Party from any
liability that it, he or she may have to such Indemnified Party under this
Article unless, and only to the extent that, the failure to give such notice
materially and adversely prejudices such Indemnifying Party.

         (b)  The Indemnifying Party shall be entitled, at its own expense, to
participate in the defense of such Third Party Action.

         (c)  The Indemnifying Party shall obtain the prior written approval of
the Indemnified Party before entering into or making any settlement, compromise,
admission, or acknowledgment of the validity of such Third Party Action or any
liability in respect thereof if such settlement, compromise, admission, or
acknowledgment (i) would impose injunctive or other equitable relief against the
Indemnified Party, or (ii) could, in the reasonable opinion of the Indemnified
Party, have a Material Adverse Effect on such Indemnified Party.

         (d)  No Indemnifying Party shall consent to the entry of any judgment
or enter into any settlement that does not include as an unconditional term
thereof the giving by each claimant or plaintiff to each Indemnified Party of a
release from all liability in respect of such Third Party Action.

    6.3  Direct Claims.  In any case in which an Indemnified Party seeks
         -------------
indemnification hereunder which is not subject to Section 6.2 because no Third
                                                  -----------
Party Claim is involved (a "direct action"), the Indemnified Party shall notify
the Indemnifying Party in writing of any Indemnified Costs which such
Indemnified Party claims are subject to indemnification under the terms hereof.
Subject to Section 6.4(b) and 6.4(d), failure of the Indemnified Party to
           --------------
exercise promptness in such notification shall not amount to a waiver of such
claim.

    6.4  Limitations. The following provisions shall limit the indemnification
         -----------
obligations hereunder:

         (a)  Minimum Loss. Subject to Section 6.5, no Indemnifying Party shall
              ------------             -----------
be required to indemnify an Indemnified Party for Indemnified Costs unless and
until the aggregate amount of all Indemnified Costs for which all Indemnified
Parties (taken together), are otherwise entitled to indemnification pursuant to
this Article exceeds $500,000 (the "Minimum Loss"). After the Minimum Loss is
exceeded, such Indemnified Parties shall be entitled to be paid the entire
amount of any Indemnified Costs from the first dollar of Indemnified Costs,
subject to the limitations on recovery and recourse set forth in this Section
                                                                      -------
6.4.

                                      -33-
<PAGE>

         (b)  Limitation as to Time. No Indemnifying Party shall be liable for
              ---------------------
any Indemnified Costs pursuant to this Article unless a written claim for
indemnification in accordance with Section 6.2 or 6.3 is given by the
Indemnified Party to the Indemnifying Party with respect thereto on or before
5:00 p.m., Santa Barbara, California time on the first anniversary of the
Closing Date (the "Expiration Date"), except that this time limitation shall be
two years for claims based upon a breach of the representations and warranties
made in Section 2.2.
        -----------

         (c)  Liability Cap. Without limiting any of the foregoing provisions of
              -------------
this Section 6.4, the Parties hereby agree that (i) the maximum liability of a
     -----------
particular Holder under this Article for Indemnified Costs shall in no event
exceed the value of the Parent Common Stock held in escrow for such Holder
pursuant to the Escrow Agreement valued as of the Effective Time, except that
the limitation set forth in this Section 6.4(c) shall not (A) apply to claims
                                 --------------
based upon a breach of the representations and warranties made in Section 2.2 or
                                                                  -----------
(B) limit the liability of any officer, director or stockholder of the Company
for such Person's fraud or intentional misrepresentation as set forth in Section
                                                                         -------
6.7. Except as contemplated above, resort to the Escrow Fund shall be the
---
exclusive contractual remedy of Parent for any Damages if the Merger closes.

         (d)  Materiality. For purposes of determining (i) whether an
              -----------
indemnifying Party shall be required to indemnify an Indemnified Party under
this Article, (ii) the aggregate amount of Minimum Loss suffered by an
Indemnified Party, or (iii) the aggregate amount of Indemnified Costs suffered
by an Indemnified Party, each representation and warranty (whether made as of
the date of this Agreement or made on and as of the Closing Date) contained in
this Agreement for which indemnification is sought hereunder shall be read
(including for purposes of determining whether a breach of such representation
or warranty has occurred) without regard to, and as if such representation or
warranty did not contain, materiality qualifications that may be contained
therein.

         (e)  Sole and Exclusive Remedy. Each Party acknowledges and agrees
              -------------------------
that, after the Closing, notwithstanding any other provision of this Agreement
to the contrary, such Party's sole and exclusive remedy with respect to
Indemnified Costs shall be in accordance with, and limited by, the provisions
set forth in this Article.

    6.5  Matters Not Subject to Minimum Loss. Notwithstanding any of the
         -----------------------------------
provisions set forth in Section 6.4, the parties hereby agree that Section
                        -----------                                -------
6.4(a) shall not limit in any way the obligations of the Company's stockholders
------
to indemnify the Indemnified Parties for Indemnified Costs arising out of claims
based upon a breach of representations and warranties made in Sections 2.9(f),
                                                              ---------------
2.9(g), 4.1(f), 4.1(g) and 4.1(l).
------  ------  ------     ------

    6.6  Escrow Arrangements.  At the Effective Time, the Escrow Amount shall be
         -------------------
placed in an escrow fund (the "Escrow Fund"), to be governed by the terms of the
Escrow Agreement.  The Escrow Fund shall be available to compensate Indemnified
Parties for Indemnified Costs.  An Indemnified Party may not receive any shares
from the Escrow Fund unless and until Officer's Certificates (as defined in
Section 5 of the Escrow Agreement) identifying Indemnified

                                      -34-
<PAGE>

Costs, have been delivered to the Escrow Agent as provided in Section 5 of the
Escrow Agreement. The terms and conditions of the Escrow Fund shall be set forth
more fully in an Escrow Agreement in the form attached hereto as Exhibit 6.6
                                                                 -----------
(the "Escrow Agreement").

    6.7  No Waiver Relating to Claims for Fraud. The liability of any Party
         --------------------------------------
under Article VI shall be in addition to, and not exclusive of, any other
      ----------
liability that such Party may have at law or equity based on such party's such
Party fraudulent acts or omissions. None of the provisions set forth in this
Agreement, including the provisions set forth in Section 6.4(a) (relating to
                                                 --------------
Minimum Loss), Section 6.4(b) (relating to limitations on the time during which
               --------------
a claim for indemnification may be brought), or Section 6.4(c) (relating to a
                                                --------------
cap on liability), shall be deemed a waiver by any Party of any right or remedy
which such Party may have at law or equity based on any other Party's willful
breach of any covenant set forth in this Agreement or any Party's fraudulent
acts or omissions, nor shall any such provisions limit, or be deemed to limit,
(a) the amounts of recoveries sought or awarded in any claim based on any other
Party's willful breach of any covenant set forth in this Agreement or any
Party's fraudulent acts or omissions, (b) the time period during which a claim
based on any other Party's willful breach of any covenant set forth in this

recourse which any party may seek against another party with respect to a claim
based on any other Party's willful breach of any covenant set forth in this
Agreement or any Party's fraudulent acts or omissions; provided, that with
respect to such rights and remedies at law or equity, the Parties further
acknowledge and agree that none of the provisions of this Section 6.7 nor any
                                                          -----------
reference to this Section 6.7 throughout this Agreement, shall be deemed a
                  -----------
waiver of any defenses which may be available in respect to actions or claims
based on any other Party's willful breach of any covenant set forth in this
Agreement or any Party's fraudulent acts or omissions, including defenses of

          --------------
used herein shall be deemed in each case to be followed by the words "without
limitation." The word "agreement" when used herein shall be deemed in each case
to mean any contract, commitment or other agreement, whether oral or written,
that is legally binding. As used in this Agreement, the phrases "to a Party's
knowledge," "a Party is not aware," and similar phrases shall mean the knowledge
of such Party, or of the officers and directors of such Party, after careful
consideration of the matters set forth in the representation that is so
qualified and a reasonably diligent review of all files, documents, agreements
and other materials in such Person's possession or subject to his or her
control. The table of contents and headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

    9.3  Counterparts. This Agreement may be executed in one or more
         ------------
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each

    9.4  Entire Agreement; Assignment. This Agreement, the schedules and
         ----------------------------
Exhibits hereto, the Related Agreements and the documents and instruments and
other agreements among the Parties referenced herein and therein (including the
Nondisclosure Agreement): (a) constitute the entire agreement among the Parties
with respect to the subject matter hereof and supersede all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof; (b) are not intended to confer upon any other Person any
rights or remedies hereunder; and (c) shall not be assigned by operation of law
or otherwise except as otherwise specifically provided, except that Parent and
Merger Sub may assign their respective rights and delegate their respective
obligations hereunder to their respective affiliates.

    9.5  Severability.  If any provision of this Agreement or the application
         ------------
thereof, becomes or is declared by a court of competent jurisdiction to be
illegal, void or unenforceable, the remainder of this Agreement will continue in
full force and effect and the application of such provision to other persons or
circumstances will be interpreted so as reasonably to effect the intent of the
parties hereto.  The Parties further agree to replace such void or unenforceable
provision of this Agreement with a valid and enforceable provision that will
achieve, to the extent possible, the economic, business and other purposes of
such void or unenforceable provision.

    9.6  Other Remedies. Except as otherwise provided herein, any and all
         --------------
remedies herein expressly conferred upon a Party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such Party, and the exercise by a Party of any one remedy will not preclude the
exercise of any other remedy.

    9.7  Governing Law.  This Agreement shall be governed by and construed in
         -------------
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
Each Party agrees that process may be served upon them in any manner authorized
by the laws of the State of Delaware for such Persons and waives and covenants
not to assert or plead any objection which they might otherwise have to such
jurisdiction and such process.

    9.8  Rules of Construction. The Parties agree that they have been
         ---------------------
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the Party drafting such agreement or document.

    9.9  Specific Performance.  The Parties agree that irreparable damage would
         --------------------
occur if any provision of this Agreement were not performed in accordance with
their specific terms or were otherwise breached.  Therefore, the Parties shall
be entitled to an injunction or injunctions to prevent breaches of this
Agreement and to enforce specifically the terms and provisions hereof in any
court of the United States or any state having jurisdiction, this being in
addition to any other remedy to which they are entitled at law or in equity.
Time is of the essence in the performance of a Party's obligations hereunder.

9.10  Survival of Representations, Warranties and Agreement.  Regardless of any
      -----------------------------------------------------
investigation at any time made by or on behalf of any Party or of any
information any Party may

                                      -42-
<PAGE>

Parent, Merger Sub or the Company hereunder or pursuant hereto or in connection
with the Transactions shall survive the Closing, but shall terminate at 5:00

representations and warranties made by the Company in Section 2.2, which
                                                      -----------
representations and warranties shall survive until the first anniversary of the
Expiration Date. Following the date of termination of a representation or
warranty, no claim can be brought with respect to a breach of such
representation or warranty, but no such termination shall affect any claim for a
breach of a representation or warranty that was asserted before the date of
termination. To the extent that such are performable after the Closing, each
covenant and agreement contained in this Agreement shall survive the Closing for
the period stated or, if no such period is stated, such covenant or agreement
shall survive indefinitely.

     9.11  Headings.  The descriptive headings contained in this Agreement are
           --------
included for convenience of reference only and shall not affect in any way the
meaning or interpretation of this Agreement

     9.12  Waiver of Jury Trial. Each of Parent, Merger Sub and the Company
           --------------------
hereby irrevocably waives all right to trial by jury in any action, proceeding
or counterclaim (whether based on contract, tort or otherwise) arising out of or
relating to this Agreement or the actions of Parent, Merger Sub or the Company
in the negotiation, administration, performance and enforcement thereof.
