         Section 2.  Required Registration.

                  (a) Subject to Section 2(b), if the Company shall be requested

Shares which the Company has been so requested to register. The number of
requests permitted pursuant to this Section 2(a) shall be unlimited.

notwithstanding, the Company shall not be obligated to effect any registration
under the Securities Act pursuant to Section 2(a) except in accordance with the
following provisions:

                     (i) with respect to any registration pursuant to this
         Section 2, the Company may include in such registration any Primary
         Shares or Other Shares; provided, however, that if the managing
         underwriter advises the Company that the inclusion of all Registrable
         Shares, Primary Shares and/or Other Shares proposed to be included in
         such registration would interfere with the successful marketing
         (including pricing) of the Registrable Shares proposed to be included
         in such registration, then the number of Registrable Shares, Primary
         Shares and/or Other Shares proposed to be included in such registration
         shall be included in the following order:

                         (A) first, all Registrable Shares requested to be
                  included in such registration by the Investors who requested
                  such registration or made timely notice to the Company of
                  their request to include Registrable Shares in such
                  registration pursuant to Section 2(a), pro rata among such
                  requesting Shareholders based on the number of Registrable
                  Shares requested by each such requesting Shareholder to be so
                  registered;

                         (B) second, all Registrable Shares requested to be
                  included in such registration by the other Shareholders who
                  requested the inclusion of their Registrable Shares in such
                  registration pursuant to Section 2(a), pro rata among all such
                  Shareholders based on the number of Registrable Shares
                  requested by each such Shareholder to be so registered;

                         (C) third, the Primary Shares; and

                         (D) fourth, the Other Shares;

                     (ii) at any time before the Registration Statement covering
         Registrable Shares becomes effective, the Shareholder or group of
         Shareholders which requested

                                      -4-
<PAGE>   7

         such registration pursuant to Section 2(a) may request the Company to
         withdraw or not to file the Registration Statement; and

                     (iii) the Company may, at its sole option, elect to satisfy
         a request for a registration pursuant to Section 2(a) on Form S-2 or
         Form S-3 promulgated under the Securities Act (or any successor forms
         thereto), if such forms are then available to the Company.

                  (c) The Company shall file a registration statement with
respect to each registration requested pursuant to Section 2(a) as soon as
practicable after receipt of the demand of the requesting Shareholders;
provided, however, that if in the good faith judgment of the Board of Directors
of the Company, such registration would be seriously detrimental to the Company
in that such registration would interfere with a proposed primary registration
of securities by the Company or any other material corporate transaction and the
Board of Directors concludes, as a result, that it is advisable to defer the
filing of such registration statement at such time (as evidenced by an
appropriate resolution of the Board), then the Company shall have the right to
defer such filing for the period during which such registration would be
seriously detrimental; provided, further, however, that (i) the Company may not
defer the filing for a period of more than one hundred and twenty (120) days
after receipt of the demand of the requesting Shareholders, (ii) the Company
shall not exercise its right to defer such a registration more than once, and
(iii) if the Company undertakes a primary registration following an exercise of
its deferral right, the holders of Registrable Shares shall have "piggyback"
rights under Section 3 hereof with respect to not less than one-third (1/3) of
the number of shares of Registrable Shares to be sold in such offering.

         Section 3.  Piggyback Registration.

                  If the Company at any time that is 180 days after its initial
Public Offering proposes for any reason to register shares of Common Stock under
the Securities Act (other than on Form S-4 or Form S-8 promulgated under the
Securities Act or any successor forms thereto), it shall promptly give written
notice to the Shareholders of its intention to so register such shares and, upon
the written request, delivered to the Company within 20 days after delivery of
any such notice by the Company, of any Shareholder to include in such
registration Registrable Shares (which request shall specify the number of
Registrable Shares proposed to be included in such registration), the Company
shall use its best efforts to cause all such Registrable Shares to be included
in such registration on the same terms and conditions as the Common Stock
otherwise being sold in such registration; provided, however, that if the
managing underwriter advises the Company that the inclusion of all Registrable
Shares requested to be included in such registration would interfere with the
successful marketing (including pricing) of the Primary Shares or Other Shares
proposed to be registered by the Company, then the number of Primary Shares,
Registrable Shares and Other Shares proposed to be included in such registration
shall be included in the following order:

                     (i) first, the Primary Shares or other Shares proposed to
         be registered by the Company; and

                                      -5-
<PAGE>   8

                     (ii) second, the Registrable Shares requested to be
         included in such registration pursuant to this Section 3, pro rata
         among the holders thereof based upon the number of Registrable Shares
         requested to be registered by each such holder; and

                     (iii) any other Shares.

         Section 4.  Registrations on Form S-3.

                  (a) Anything contained in Section 2 to the contrary
notwithstanding, at such time as the Company shall have qualified for the use of
Form S-3 promulgated under the Securities Act or any successor form thereto, a
Majority of Shareholders shall have the right to request in writing an unlimited
number of registrations of Registrable Shares on Form S-3 or such successor
form, which request or requests shall (i) specify the number of Registrable
Shares intended to be sold or disposed of and the holders thereof, (ii) state
the intended method of disposition of such Registrable Shares and (iii) relate
to Registrable Shares having an anticipated aggregate gross offering price
(before underwriting discounts and commissions) of at least $10,000,000, and
upon receipt of any such request, the Company shall use its best efforts
promptly to effect the registration under the Securities Act of the Registrable
Shares so requested to be registered. A requested registration on Form S-3 or
any such successor form in compliance with this Section 4 shall be treated as a
registration initiated pursuant to, and shall be subject to, the provisions of
Section 2.

                  (b) Subject to the further provisions of this Section 4(b), if
at any time after the first anniversary of this Agreement the Strategic Investor
requests that the Company include Registrable Shares for sale to the public
pursuant to a registration statement filed under the Securities Act on Form S-3
(including any successor form thereto), the Company shall use its best efforts
to promptly effect the registration under the Securities Act of such Registrable
Shares. Notwithstanding the foregoing provisions of this Section 4(b), the
Company shall not be obligated to effect any such registration pursuant to this
Section 4(b):

                      (i) if Form S-3 (or any successor or similar form) is not
         available for such offering; or

                      (ii) if the Strategic Investor proposes to sell
         Registrable Shares with an anticipated aggregate gross offering price
         (before underwriting discounts and commissions) to the public of less
         than five million dollars ($5,000,000); provided, however, that if the
         Strategic Investor has not previously requested a registration pursuant
         to this Section 4(b) and the anticipated aggregate gross offering price
         (before underwriting discounts and commissions) to the public of all
         Registrable Shares then held by the Strategic Investor is less than
         five million dollars ($5,000,000), then the Strategic Investor may
         request that the Company register all (but not less than all) of its
         Registrable Shares pursuant to this Section 4(b); or

                      (iii) if the Strategic Investor receives the written offer
         from the Company contemplated pursuant to Section 2(a), Section 3 or

                                      -6-
<PAGE>   9

         Section 4(a) hereof to include Registrable Shares in a registration
         contemplated pursuant to Section 2(a), Section 3 or Section 4(a) hereof
         within ten days after making its request for registration pursuant to
         this Section 4(b); or

                      (iv) if the Company shall furnish to the Strategic
         Investor a certificate signed by the Chairman of the Board of Directors
         of the Company stating that in the good faith judgment of the Board of
         Directors of the Company, it would be seriously detrimental to the
         Company and its stockholders for such registration to be effected at
         such time, in which event the Company shall have the right to defer the
         filing of such registration statement for a period of not more than one
         hundred and twenty (120) days after receipt of the request of the
         Strategic Investor under this Section 4(b); provided, that such right
         to delay a request shall be exercised by the Company not more than once
         in any twelve (12) month period; or

                      (v) if the Company has, within the twelve (12) month
         period preceding the date of such request, already effected one (1)
         registration pursuant to a request made pursuant to this Section 4(b).

         Section 5.  Holdback Agreement.

                  (a) If the Company at any time shall register shares of Common
Stock under the Securities Act (including any registration pursuant to Section
2, Section 3 or Section 4) for sale to the public pursuant to an underwritten
offering, the Shareholders shall not sell publicly, make any short sale of,
grant any option for the purchase of, or otherwise dispose publicly of, any
Registrable Shares (other than those shares of Common Stock included in such
registration pursuant to Sections 2, 3 or 4) without the prior written consent
of the Company, for a period designated by the Company in writing to the
Shareholders, which period shall not begin more than 10 days prior to the
effectiveness of the Registration Statement pursuant to which such public
offering shall be made and shall not last more than 180 days after the closing
of sale of shares pursuant to such Registration Statement. The Company shall use
reasonable efforts to obtain the agreement of any Person permitted to sell
shares of Common Stock in a registration to be bound by and to comply with this
Section 5 with respect to such registration as if such Person was a Shareholder
hereunder.

                  (b) If the Company at any time pursuant to Section 2 or
Section 3 of this Agreement shall register under the Securities Act Registrable
Shares held by Shareholders for sale to the public pursuant to an underwritten
offering the Company shall not effect any public sale or distribution of
securities similar to those being registered, or any securities convertible into
or exercisable or exchangeable for such securities, for such period as shall be
determined by the managing underwriters, which period shall not begin more than
10 days prior to the effectiveness of the Registration Statement pursuant to
which such public offering shall be made and shall not last more than 180 days
after the closing of sale of shares pursuant to such Registration Statement.

         Section 6.  Preparation and Filing.

                  (a) If and whenever the Company is under an obligation
pursuant to the provisions of this Agreement to use its best efforts to effect
the registration of, and keep effective a

                                      -7-

Registration Statement for, any Registrable Shares, the Company shall, as
expeditiously as practicable:

                      (i) use its best efforts to cause a Registration Statement
         that registers such Registrable Shares to become and remain effective
         for a period of 90 days (extended for such period of time as the
         Shareholders are required to discontinue disposition of Registrable
         Shares pursuant to Section 6(b) below) or until all of such Registrable
         Shares have been disposed of (if earlier);

                      (ii) use its best efforts to furnish, at least five
         business days before filing a Registration Statement that relates to
         the registration of such Registrable Shares, a Prospectus relating
         thereto or any amendments or supplements relating to such a
         Registration Statement or Prospectus, to one counsel (the

         of all such documents proposed to be filed;

                      (iv) notify in writing the Shareholders' Counsel, and the
         Shareholders whose Registrable Shares may be included in such
         Registration Statement, promptly of (A) the receipt by the Company of

         respect to such Registration Statement or Prospectus or any amendment
         or supplement thereto or any request by the Commission for the amending
         or supplementing thereof or for additional information with respect
         thereto, (B) the receipt by the Company of any notification or written
         information with respect to the issuance or threatened issuance by the
         Commission of any stop order suspending the effectiveness of such

         thereto or the initiation or threatening of any proceeding for that
         purpose (and the Company shall use its best efforts to prevent the
         issuance thereof or, if issued, to obtain its withdrawal) and (C) the
         receipt by the Company of any notification with respect to the
         suspension of the qualification of such Registrable Shares for sale in
         any jurisdiction or the initiation or threatening of any proceeding for
         such purposes;

                      (v) use its best efforts to register or qualify such
         Registrable Shares under such other securities or blue sky laws of such
         jurisdictions as the Shareholders holding such Registrable Shares
         reasonably request and do any and all other acts and things which may
         be reasonably necessary or advisable to enable the Shareholders to
         consummate the disposition in such jurisdictions of the Registrable
         Shares owned by the Shareholders; provided, however, that the Company
         will not be required to qualify generally to do business, subject
         itself to general taxation or consent to general service of process in
         any jurisdiction where it would not otherwise be required to do so but
         for this clause (v);

                      (vi) furnish to the Shareholders holding such Registrable
         Shares such number of copies of a summary Prospectus, if any, or other

<PAGE>   11

         such other documents as such Shareholders may reasonably request in
         order to facilitate the public sale or other disposition of such
         Registrable Shares;

                      (vii) use its best efforts to cause such Registrable
         Shares to be registered with or approved by such other governmental
         agencies or authorities as may be necessary by virtue of the business
         and operations of the Company to enable the Shareholders holding such
         Registrable Shares to consummate the disposition of such Registrable
         Shares;

                      (viii) notify the Shareholders holding such Registrable
         Shares on a timely basis at any time when a Prospectus relating to such
         Registrable Shares is required to be delivered under the Securities Act
         within the appropriate period mentioned in clause (i) of this Section
         6(a), of the happening of any event as a result of which the Prospectus
         included in such Registration Statement, as then in effect, includes an
         untrue statement of a material fact or omits to state a material fact
         required to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading, and prepare and furnish to such Shareholders a reasonable
         number of copies of, and file with the Commission, a supplement to or
         an amendment of such Prospectus as may be necessary so that, as
         thereafter delivered to the offerees of such shares, such Prospectus
         shall not include an untrue statement of a material fact or omit to
         state a material fact required to be stated therein or necessary to
         make the statements therein, in light of the circumstances under which
         they were made, not misleading;

                      (ix) subject to the execution of confidentiality
         agreements in form and substance reasonably satisfactory to the
         Company, make available upon reasonable notice and during normal
         business hours, for inspection by the Shareholders holding Registrable
         Shares requested to be included in such registration, any underwriter
         participating in any disposition pursuant to such Registration
         Statement and any attorney, accountant or other agent retained by the
         Shareholders or underwriter (collectively, the "Inspectors"), all
         pertinent financial and other records, pertinent corporate documents
         and properties of the Company (collectively, the "Records"), and cause
         the Company's officers, directors and employees to supply all
         information (together with the Records, the "Information") reasonably
         requested by any such Inspector, in each case as shall be reasonably
         necessary to enable them to exercise their due diligence responsibility
         in connection with such Registration Statement; provided, however, that
         any of the Information that the Company determines in good faith to be
         confidential, and of which determination the Inspectors are so
         notified, shall not be disclosed by the Inspectors unless (A) the
         disclosure of such Information is necessary to avoid or correct a
         misstatement or omission in the Registration Statement or Prospectus,
         (B) the release of such Information is ordered pursuant to a subpoena
         or other order from a court of competent jurisdiction or, upon the
         written advice of counsel, is otherwise required by law, or (C) such
         Information has been made generally available to the public, and the
         Shareholders agree that they will, upon learning that disclosure of
         such Information is sought in a court of competent jurisdiction, give
         notice to the Company and allow the Company, at the Company's expense,
         to undertake appropriate action to prevent disclosure of the
         Information deemed confidential;

                                      -9-

                      (x) use its best efforts to obtain from its independent
         certified public accountants "cold comfort" letters in customary form
         and at customary times and covering matters of the type customarily
         covered by cold comfort letters;

                      (xi) use its best efforts to obtain from its counsel an
         opinion or opinions in customary form naming the Shareholders as
         additional addressees or parties who may rely thereon;

                      (xii) provide a transfer agent and registrar (which may be
         the same entity and which may be the Company) for such Registrable
         Shares;

                      (xiii) issue to any underwriter to which the Shareholders
         holding such Registrable Shares may sell shares in such offering
         certificates evidencing such Registrable Shares;

                      (xiv) list such Registrable Shares on any national
         securities exchange on which any shares of the Common Stock are listed
         or, if the Common Stock is not listed on a national securities
         exchange, use its best efforts to qualify such Registrable Shares for
         inclusion on the Nasdaq National Market;

                      (xv) otherwise use its best efforts to comply with all
         applicable rules and regulations of the Commission and make available
         to its securityholders, as soon as reasonably practicable, earnings
         statements (which need not be audited) covering a period of 12 months
         beginning within three months after the effective date of the
         Registration Statement, which earnings statements shall satisfy the
         provisions of Section 1l(a) of the Securities Act; and

                      (xvi) use its best efforts to take all other steps
         necessary to effect the registration of, and maintain an effective
         Registration Statement with respect to, such Registrable Shares
         contemplated hereby.

                  (b) Each holder of the Registrable Shares, upon receipt of any
notice from the Company of any event of the kind described in Section 6(a)(viii)
hereof, shall forthwith discontinue disposition of the Registrable Shares
pursuant to the Registration Statement coveting such Registrable Shares until
such holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 6(a)(viii) hereof, and, if so directed by the Company,
such holder shall deliver to the Company all copies, other than permanent file
copies then in such holders possession, of the most recent Prospectus covering
such Registrable Shares at the time of receipt of such notice.

         Section 7.  Expenses.

                  All expenses (other than underwriting discounts and
commissions relating to the Registrable Shares) incurred by the Company and the
Shareholders in complying with this Agreement, including, without limitation,
all registration and filing fees (including all expenses incident to filings
with the National Association of Securities Dealers, Inc.), fees and expenses of
complying with securities and blue sky laws, printing expenses, fees and
expenses of the Company's counsel and accountants and fees and expenses of the
Shareholders' Counsel, shall be

                                      -10-
<PAGE>   13

paid by the Company in connection with registrations requested under Section 2
or Section 4; provided, however, that all underwriting discounts and selling
commissions applicable to the Registrable Shares and Other Shares shall be borne
by the holders selling such Registrable Shares and Other Shares, in proportion
to the number of Registrable Shares and Other Shares sold by each such holder.

         Section 8.  Indemnification.

                  (a) In connection with any registration of any Registrable
Shares under the Securities Act pursuant to this Agreement, the Company shall
indemnify and hold harmless, to the fullest extent permitted by law, each holder
of Registrable Shares, each underwriter, broker or any other Person acting on
behalf of the holders of Registrable Shares and each other Person, if any, who
controls any of the foregoing Persons within the meaning of the Securities Act
(each such indemnified Person being referred to herein as an "Indemnified
Person") against any losses, claims, damages or liabilities, joint or several
(or actions in respect thereof), to which any of the foregoing Persons may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon an untrue statement or allegedly untrue statement of a material
fact contained in or incorporated by reference in the Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary Prospectus or final Prospectus contained therein or otherwise
filed with the Commission, any amendment or supplement thereto or any document
incident to registration or qualification of any Registrable Shares, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading or, with respect to any Prospectus, necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or any violation by the Company of the Securities Act or state
securities or blue sky laws applicable to the Company and relating to action or
inaction required of the Company in connection with such registration or
qualification under such state securities or blue sky laws; and shall promptly
reimburse the Indemnified Persons for any legal or other expenses reasonably
incurred by any of them in connection with investigating or defending any such
loss, claim, damage, liability or action; provided, however, that the Company
shall not be liable in any such case to any such Indemnified Person to the
extent that any such loss, claim, damage, liability or action (including any
legal or other expenses incurred) arises out of or is based upon: (i) an untrue
statement or allegedly untrue statement or omission or alleged omission made in
said Registration Statement, preliminary Prospectus, final Prospectus,
amendment, supplement or document incident to registration or qualification of
any Registrable Shares in reliance upon and in conformity with written
information furnished to the Company through an instrument duly executed by such
Indemnified Person specifically for use in the preparation thereof or (ii) any
Indemnified Person's failure to deliver a copy of the Prospectus (including any
amendment or supplement thereto) after the Company has delivered to such
Indemnified Person a sufficient number of copies of the same.

                  (b) In connection with any registration of Registrable Shares
under the Securities Act pursuant to this Agreement, each holder of Registrable
Shares being registered shall, severally and not jointly, to the fullest extent
permitted by law, indemnify and hold harmless (in the same manner and to the
same extent as set forth in Section 8(a) above) the Company, each director of
the Company, each officer of the Company who shall have signed such Registration

                                      -11-
<PAGE>   14

Statement, each other holder of Registrable Shares or Other Shares, each agent,
underwriter, broker or other Person acting on behalf of the Company, each other
holder of Registrable Shares or Other Shares and each Person who controls any of
the foregoing Persons within the meaning of the Securities Act with respect to
any statement or omission from such Registration Statement, any preliminary
Prospectus or final Prospectus contained therein or otherwise filed with the
Commission, any amendment or supplement thereto or any document incident to
registration or qualification of any Registrable Shares, if such statement or
omission was made in reliance upon and in conformity with written information
furnished to the Company or such underwriter through an instrument duly executed
by such holder specifically for use in connection with the preparation of such
Registration Statement, preliminary Prospectus, final Prospectus, amendment,
supplement or document; provided, however, that the maximum amount of liability
in respect of such indemnification shall be limited, in the case of each seller
of Registrable Shares, to an amount equal to the net proceeds actually received
by such seller from the sale of Registrable Shares effected pursuant to such
registration.

                  (c) Promptly after receipt by an indemnified party of notice
of the commencement of any action involving a claim referred to in Section 8(a)
or Section 8(b), such indemnified party will, if a claim in respect thereof is
made against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, however, that the indemnified party's
failure to give such notice shall not release, relieve or in any way affect the
indemnifying party's obligation hereunder to indemnify the indemnified party
unless and to the extent that the rights of the indemnifying party are
prejudiced thereby. In case any such action is brought against an indemnified
party, the indemnifying party will be entitled to participate in and to assume
the defense thereof, jointly with any other indemnifying party similarly
notified to the extent that he, she, or it may wish, with counsel reasonably
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of his, her or its election so to assume the
defense thereof, the indemnifying party shall not be responsible for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof, provided, however, that if any indemnified party shall
have reasonably concluded (based on the written advice of counsel) that there
may be one or more legal or equitable defenses available to such indemnified
party which are additional to or conflict with those available to the
indemnifying party, or that such claim or litigation involves or could have an
effect upon matters beyond the scope of the indemnity agreement provided in this
Section 8, the indemnifying party shall not have the right to assume the defense
of such action on behalf of such indemnified party and such indemnifying party
shall reimburse such indemnified party and any Person controlling such
indemnified party for that portion of the fees and expenses of any counsel
retained by the indemnified party which is reasonably related to the matters
covered by the indemnity agreement provided in this Section 8.

                  (d) If the indemnification provided for in this Section 8 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, claim, damage, liability or action referred to
herein (other than as a result of the applicability of the proviso in Section
8(a)), then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amounts paid or payable by such
indemnified party as a result of such loss, claim,

                                      -12-
<PAGE>   15

damage, liability or action in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the statements or omissions which resulted
in such loss, claim, damage, liability or action as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and of
the indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

         Section 9.  Underwriting Agreement.

                  (a) If any registration pursuant to Section 2 or Section 4 is
requested to be an underwritten offering, the Company shall negotiate in good
faith to enter into a reasonable and customary underwriting agreement with the
underwriters thereof. The Company shall be entitled to receive indemnities from
lead institutions, underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the same
extent as provided above with respect to information so furnished in writing by
such Persons specifically for inclusion in any Prospectus or Registration
Statement and to the extent customary given their role in such distribution.

                  (b) No Shareholder may participate in any registration
hereunder that is underwritten unless such Shareholder agrees to (i) sell such
Shareholder's Registrable Shares proposed to be included therein on the basis
provided in any underwriting arrangements approved by the Company and a majority
of the Registrable Shares being included in such registration and (ii) as
expeditiously as possible, notify the Company of the occurrence of any event
concerning such Shareholder as a result of which the Prospectus relating to such
registration contains an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

         Section 10.  Information by Holder.

                  The Shareholders shall furnish to the Company such written
information regarding the Shareholders and the distribution proposed by the
Shareholders as the Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in this Agreement.

         Section 11.  Exchange Act Compliance.

                  From the Registration Date or such earlier date as a
Registration Statement filed by the Company pursuant to the Exchange Act
relating to any class of the Company's securities shall have become effective,
the Company shall comply with all of the reporting requirements of the Exchange
Act applicable to it (whether or not it shall be required to do so) and shall
comply with all other public information reporting requirements of the
Commission which are conditions to the availability of Rule 144 for the sale of
the Common Stock. The Company shall cooperate with the Shareholders in supplying
such information as may be necessary for the Shareholders to complete and file
any information reporting forms presently or hereafter required by the
Commission as a condition to the availability of Rule 144.

                                      -13-
<PAGE>   16

         Section 12.  Mergers, Etc.

                  The Company shall not, directly or indirectly, enter into any
merger, consolidation or reorganization in which the Company shall not be the
surviving corporation unless the surviving corporation shall, prior to such
merger, consolidation or reorganization, agree in writing to assume the
obligations of the Company under this Agreement, and for that purpose references
hereunder to "Registrable Shares" shall be deemed to include the shares of
common stock, if any, or other securities that the Shareholders would be
entitled to receive in exchange for Common Stock under any such merger,
consolidation or reorganization; provided, however, that, to the extent the
Shareholders receive securities that are by their terms convertible into shares
of common stock of the issuer thereof, then any such shares of common stock as
are issued or issuable upon conversion of said convertible securities shall be
included within the definition of "Registrable Shares."

         Section 13.  New Certificates.

                  As expeditiously as possible after the effectiveness of any
Registration Statement filed pursuant to this Agreement, the Company will
deliver in exchange for any legended certificate evidencing Registrable Shares
so registered, new stock certificates not bearing any restrictive legends.

         Section 14.  No Conflict of Rights; Selection of Underwriter.

                  The Company shall not, at any time after the date hereof,
grant any registration rights that conflict with or impair, or have any parity
with or priority over, the registration rights granted hereby. In any Public
Offering, the managing underwriter shall be a nationally recognized investment
banking firm chosen by the Board.

         Section 15.  Termination.

                  This Agreement shall terminate and be of no further force or
effect upon the written agreement of the Company, a majority of Registrable
Shares held by the Investors (which majority must include the affirmative vote
of all Registrable Shares then held by UBS) and a majority of Registrable Shares
held by all other Shareholders (which majority must include the affirmative vote
of all Registrable Shares then held by the Strategic Investor) or when there
shall no longer be any Restricted Shares outstanding.

         Section 16.  Miscellaneous.

                  (a) Successors and Assigns. Except as expressly set forth
herein, this Agreement shall bind and inure to the benefit of the Company and
the Shareholders and, subject to Section 16(b), the respective successors and
assigns of the Company and the Shareholders. This Agreement is not intended to
create any third party beneficiaries.

                  (b) Assignment. Each Shareholder may assign its rights
hereunder to any purchaser or transferee of Registrable Shares; provided,
however, that such purchaser or transferee shall, as a condition to the
effectiveness of such assignment, unless already a party to this Agreement, be
required to execute a counterpart to this Agreement agreeing to be treated as

                                      -14-
<PAGE>   17

Shareholder hereunder, whereupon such purchaser or transferee shall have the
benefits of and shall be subject to the restrictions contained in this Agreement
as if such purchaser or transferee was originally included in the definition of
a Shareholder and had originally been a party hereto.

                  (c) Severability. It is the desire and intent of the parties
hereto that the provisions of this Agreement be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought. Accordingly, if any particular provision of this
Agreement shall be adjudicated by a court of competent jurisdiction to be
invalid, prohibited or unenforceable for any reason, such provision, as to such
jurisdiction, shall be ineffective, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of this
Agreement or affecting the validity or enforceability of such provision in any
other jurisdiction. Notwithstanding the foregoing, if such provision could be
more narrowly drawn so as not to be invalid, prohibited or unenforceable in such
jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without
invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of such provision in any other jurisdiction.

                  (d) Entire Agreement. This Agreement and the other writings
referred to herein or delivered pursuant hereto contain the entire agreement
among the parties with respect to the subject matter hereof and thereof and
supersede all prior and contemporaneous arrangements or understandings with
respect hereto and thereto (including, without limitation, the Existing
Agreement).

                  (e) Notices. All communications hereunder to any party shall
be deemed to be sufficient if contained in a written instrument delivered in

                    (CVG REFERENCE NO. 200000285 AND U-0337)

         This Master Agreement (hereinafter referred to as "Agreement") is made
and entered into as of March 31, 2000 (the "Effective Date"), by and between
Cinergy Services, Inc., a Delaware corporation with a place of business at 139

at 6399 South Fiddler's Green Circle, Suite 600, Englewood, CO 80111
(hereinafter referred to as "CONVERGENT") (collectively hereinafter referred to
as "Parties").

WHEREAS, CONVERGENT represents that it is capable of providing to CSI with
e-commerce, Digital Utility and other technical and management services as

1.1      CONVERGENT shall provide to CSI various professional, technical and

Services.

1.2         During the term of this Agreement, the Parties shall have executive
meetings no less frequently than monthly on or before the fifth day of each
calendar month (by telephone conference or as otherwise agreed upon by the
Parties) to discuss and determine the specific Scopes of Work to be performed by
CONVERGENT, typically over the next 30-120 days (including modifications to
existing Scopes of Work) as well as the Work performed during the preceding
months and the leveling of Work under this Agreement in light of the
requirements of this Section and Section 6.2. The first such meeting shall be
held within five days after the execution of this Agreement. Such executive
meetings shall be attended by appropriate personnel of each party that are
authorized to act on behalf of such Party in all matters pertaining to the
applicable Scopes of Work. The initial representatives for the executive
meetings shall be as listed on Exhibit 1.2C, which shall be completed by the
parties and added to this Agreement within ten days after the execution of this
Agreement. Each of the Parties may change such designated representatives upon
written notice to the other. At such executive meetings, the Parties (a) each
may propose specific items of work (including modifications) to be contained in
current and future Scopes of Work and (b) specifically shall discuss and agree
upon resource allocation and procurement requirements with respect to such
Scopes of Work. CONVERGENT shall prepare a "Task Authorization" detailing the
proposed Scopes of Work agreed upon by the Parties, and, if accepted by CSI,
shall become a Scope of Work to be attached to this Agreement. The Parties
diligently shall work to ensure that a minimum of $1,600,000 in Work are
identified, contracted and, where possible, performed in each calendar month
during the term of this Agreement. CONVERGENT shall guaranty that it will have
the personnel and resources available to perform the Task Authorization in the
designated time. The initial team of people that will work on CSI Work is
attached as Exhibit 1.2A. Such list is subject to revision by CONVERGENT from
time to time in accordance with good commercial practices and as necessary in
order to better and more effectively serve CSI. CONVERGENT's current hourly rate
sheet as of March 31, 2000 is attached as Exhibit 1.2B.

1.3         All Work shall be performed in accordance with sound and generally
accepted professional practices and industry standards by professional,
managerial and administrative personnel fully qualified in the respective
professional disciplines required.

1.4         CONVERGENT shall have the professional, managerial or technical
responsibility for the validity, accuracy and reliability of the Work performed
to the reasonable satisfaction of CSI in accordance with mutually determined
acceptance criteria.

2.1         This Agreement and the Schedules hereto constitute the entire
agreement and understanding of the Parties with respect to the subject matter
hereof and supersede and replace all prior agreements and understandings,

(CVG Reference No. U159) as amended from time to time (the "Previous

Agreement, revise existing maintenance agreements to provide for new levels of

Scope of Work in writing or other written agreement, duly executed by both
Parties.

2.3      The Parties further agree to negotiate in good faith the terms and
conditions of a Strategic Relationship Agreement that shall be executed by the
Parties no later than 30 days after the Effective Date.

payments due CONVERGENT employees on account of, or in connection with, this
Agreement.

3.2      CONVERGENT employees assisting CSI under this Agreement ("Project
Personnel") who are found, in CSI's sole opinion, to be unsatisfactory for

another CONVERGENT employee satisfactory to CSI as soon as possible.

4.       PATENTS AND INVENTIONS

4.1      Deliverable Products and other materials furnished by CONVERGENT.

         4.1.1    CONVERGENT has developed numerous proven proprietary materials
         which provide the methodologies for the development of the Deliverable
         Products (if any, as agreed upon and defined in a particular Scope of
         Work) and may be used in connection with the Work. CSI agrees that
         CONVERGENT shall own all such products, materials, and methodologies
         and that CSI shall have or obtain no rights in such proprietary
         products, materials, and methodologies except pursuant to a separate
         written agreement executed by the Parties. CSI understands that
         CONVERGENT proprietary costs analysis and strategic planning models and
         facilities database and internet related models and designs or certain
         software products may be used under this Agreement and CSI agrees not
         to exhibit, distribute, or otherwise disclose any such proprietary
         methods and materials to external or third parties without prior
         approval in writing from CONVERGENT. Except as may be otherwise
         provided in a separate written agreement executed by the Parties,
         CONVERGENT shall continue to market, distribute, make derivative works
         from and sell similar work to other companies without further notice to
         nor consent from CSI. Nothing in this Agreement shall restrict or
         prohibit CONVERGENT's right to use concepts, techniques, and know-how
         used or developed in the course of performing the Work.

         4.1.2    CONVERGENT shall be the owner of copyright or other
         intellectual property rights in any Deliverable Products. CONVERGENT
         grants to CSI a perpetual unrestricted, royalty-free, nonexclusive
         license to reproduce and use, for CSI's internal purposes only, any
         materials developed for CSI related to this Agreement, not including
         Third Party Software. CSI shall not exhibit, distribute, or otherwise
         disclose any proprietary software, methods, or materials to external
         or

         third parties without prior approval in writing from CONVERGENT. For
         purposes of this Section 4.1.2, "third parties" (A) includes (i) any
         party which provides services external to the current Cinergy Corp.
         service enterprise, which includes the utility service geographic area
         served by Cinergy Corp. and the current CSI Affiliates through
         electric distribution lines or natural gas extensions owned by Cinergy
         Corp. and the current CSI Affiliates, but specifically excludes
         geographic areas in which Cinergy Corp. and the current CSI Affiliates
         provide energy as a commodity over distribution lines or extensions
         owned by others, and (ii) any party which provides goods and services
         other than electricity, water, steam or natural gas and any extensions
         thereof; notwithstanding that fact that such party may later become a
         CSI Affiliate (as such term is defined in Section 4.1.3 below)
         following an acquisition or merger and (B) excludes any entity which
         is a CSI Affiliate as of the Effective Date.

         4.1.3    The CONVERGENT grant of a license for CSI to use the Custom
         Software includes the right of any entity which is a CSI Affiliate as
         of the Effective Date to use the Custom Software for such CSI
         Affiliate's internal business purposes only. "CSI Affiliate" means (i)
         Cinergy Corp. and any entity in which the voting and equity interests
         are owned 50% or more by Cinergy Corp. (provided that if Cinergy Corp.
         is the surviving entity in a merger or consolidation, the requirements
         of clause (ii) below are satisfied with respect to Cinergy Corp.
         following such merger or consolidation), and (ii) the surviving entity
         in any merger or consolidation involving Cinergy Corp., provided that
         the stockholders of Cinergy Corp. continue to own not less than 50% of
         the voting and equity interests of such entity following such merger or
         consolidation. Once a CSI Affiliate has been licensed to use the Custom
         Software pursuant to this Section 4.1.3, it shall retain such license
         notwithstanding the fact that it shall no longer qualify as a CSI
         Affiliate. CSI shall be entitled to extend the license granted in this
         Section 4.1.2 to new Cinergy Corp. service territories and to third
         parties which become CSI Affiliates after the Effective Date, provided
         CSI pays a license fee equal to 50% of the original license fee price
         determined on a per customer or similar basis at the time the original
         license fee was paid; and provided further that this sentence shall not
         apply to the limited list of entities set forth on Exhibit 4.1.3. For
         example, assume that CSI pays a license fee of $150,000 for Custom
         Software at a time when CSI has 1.5 Million customers. Further assume
         that CSI subsequently acquires a new wholly-owned subsidiary with 1.0
         Million customers. To extend the license for the Custom Software to the
         new wholly-owned subsidiary, CSI would be required to pay a license fee
         of $50,000 ([1.0 Million divided by 1.5 Million] x $150,000 x 50%). CSI
         and the CSI Affiliates agree not to exhibit, distribute, or otherwise
         disclose any of the proprietary software, methods, or materials to
         third parties without prior approval in writing by CONVERGENT.

         4.1.4    This Section 4.1 applies to Deliverable Products provided
         under this Agreement and to the Custom Software already developed by
         CONVERGENT under Agreements U159 and U290.

4.2      Third Party Software licenses typically will be executed between CSI
and the Third Party Software vendors. Grants of licenses for all Third Party
Software licenses will be transferred from the third party to CSI in accordance
with a mutually acceptable license agreement.

5.       PRICING

5.1      The price for the Work performed by CONVERGENT during the term of this
Agreement is $40,000,000.00 (the "Total Price"), payable as follows:

         5.1.1   Subject to Section 6.2, CSI shall pay to CONVERGENT a minimum
         of $1,600,000.00 of the Total Price each calendar month during the
         term of this Agreement regardless of the amount of Work performed
         during such calendar month (the "Minimum Monthly Payment"). If the
         Work completed or to be performed by CONVERGENT exceeds or is expected
         to exceed the Minimum Monthly Payment for a calendar month, then CSI
         shall be required to pay such amount in addition to the Minimum
         Monthly Payment (the "Additional Payment") as required by Article 6.

         5.1.2   To the extent that CSI has paid CONVERGENT less than the Total
         Price by the 24th month of this Agreement, regardless of the actual
         Work performed by CONVERGENT, then CONVERGENT shall be entitled to
         invoice, and CSI shall pay, the difference between the Total Price and
         the amount actually paid by CSI during the term of the Agreement.

         5.1.3   Reasonable expenses incurred by CONVERGENT in performing the
         Work, including, but not limited to, air transportation, auto rental,
         rail transportation, cabs, parking, lodging and meals, express air
         shipments, data transmittal, telephone calls, copying costs, and
         similar expenses and costs ("Incidental Expenses") shall be billed to
         and paid by CSI at CONVERGENT's actual cost. Incidental Expenses shall
         not be counted towards satisfying any Minimum Monthly Payment,
         Additional Payment, or the Total Price. CONVERGENT shall provide CSI
         with a monthly receipt of its Incidental Expenses in such detail as is
         reasonably acceptable to CSI.

         5.1.4   Approximately 75% of the Total Price shall be allocated by CSI
         towards payment for CONVERGENT's core professional, management and
         related technical services (i.e., approximately 25% of the Total Price
         may be allocated by CSI towards non-labor products or services). The
         Parties shall monitor the percentage allocations called for pursuant
         to this Section and may from time to time adjust the targeted
         percentage allocation upon mutual agreement.

         5.1.5   CSI shall pay all taxes, however designated, associated with
         the Work or otherwise payable hereunder, exclusive of taxes based on
         the net income of CONVERGENT or taxes related to employees or agents
         of CONVERGENT (e.g. social security payments for CONVERGENT
         employees). If any charges under this Agreement are exempt from sales
         or use tax liability, CSI shall provide to CONVERGENT, upon execution
         of this Agreement, evidence of tax exemption acceptable to the
         relevant taxing authority.

         5.1.6   All Work performed by CONVERGENT under this Agreement shall be
         billed to CSI at CONVERGENT's then current standard rates or on a
         fixed price basis as quoted by CONVERGENT and agreed to by CSI.
         Notwithstanding anything to the contrary in this Agreement, nothing in
         this Agreement shall require CSI to pay CONVERGENT more than the Total
         Price unless agreed to by the Parties in a Scope of Work. During the
         term of this Agreement, CONVERGENT shall update the rate sheet in
         Exhibit 1.2B to keep it current and CONVERGENT shall not increase the
         hourly rates of its employees or agents in a manner which is

         inconsistent with the rates charged to other comparable clients with
         respect to comparable assignments.

6.       PAYMENT

6.1      CONVERGENT shall issue invoices for the Minimum Monthly Payment and
the Additional Payment (if any) within the ten (10) days of the end of each
calendar month for which such Minimum Monthly Payment and Additional Payment
(if any) applies (i.e., monthly in arrears), and CSI shall pay each such
invoice within 15 days after receipt of invoice.

6.2      During the term of this Agreement, every three months there will be a
quarterly reconciliation statement and true-up (the "True-Up") detailing how
previous Minimum Monthly Payments and Additional Payments have been applied
towards Work completed or to be performed. The True-Up will reflect whether
Additional Payments are due or the extent to which Minimum Monthly Payments
and/or Additional Payments previously received shall be credited against any
Minimum Monthly Payments and/or Additional Payments currently due because
either the Work has not been performed up to the total amount paid or the Work
was not performed in accordance with mutually determined acceptance criteria.
Notwithstanding the foregoing, no overpayments by CSI as determined by the
True-Up shall be credited against Minimum Monthly Payments to be made with
respect to the period from the Effective Date through July 31, 2000. The first
True-Up during calendar 2000 shall be performed in August, 2000 with respect to
work performed through July 31, 2000, and the results will be applied with
respect to the payments to be made in September, 2000 with respect to August,
2000 and, if necessary, with respect to subsequent months. The second True-Up
during calendar 2000 shall be performed in October, 2000 and the results will
be applied with respect to the payments to be made in November, 2000 with
respect to October, 2000 and, if necessary, with respect to subsequent months.
Thereafter, True-Ups shall be performed following each calendar quarter.
Notwithstanding the foregoing, overpayments by CSI shall be credited against
the Minimum Monthly Payments to be made with respect to the period from July
31, 2000 through December 31, 2000 only to the extent that the amount overpaid
by CSI exceeds 115% of the Work performed during such period. After December
31, 2000, overpayments made by CSI as determined by the True-Up with respect to
all periods shall be fully credited against subsequent Minimum Monthly Payments
and Additional Payments. At the end of the term of this Agreement, if
CONVERGENT has not performed Work valued at the Total Price in accordance with
mutually determined acceptance criteria, then this Agreement shall extend until
CONVERGENT has provided Work to that level at no charge to CSI (other than
Incidental Expenses). The Parties acknowledge the importance of leveling the
Work to be performed and any material monthly shortfall between the Work
performed to date and cumulative Minimum Monthly Payments shall be escalated to
senior management of the parties, initially Glenn E. Montgomery, Jr., CEO of
CONVERGENT and Larry Thomas, President of CSI, for their consideration.

6.3      In the event that an invoice remains unpaid for thirty (30) days after
the date it is received by CSI, CONVERGENT may charge CSI interest at the rate
of 1 1/2 percent per month on the unpaid balance of said invoice from date of
its receipt by CSI.

6.4      All invoices will be addressed to:

7.      TERM OF AGREEMENT

7.1     The term of this Agreement shall commence on the Effective Date and
terminate on March 31, 2002, and except as specifically provided in this
Section 7.1, this Agreement shall be neither cancelable nor subject to early
termination during the term hereof. The foregoing notwithstanding, in the event
either Party has materially breached any material term of this Agreement, the
other Party may provide the breaching Party with written notice of default. If
the breaching Party fails to cure such breach within 40 days of written notice
thereof, the non-breaching Party may immediately terminate this Agreement by
written notice to the other Party. In addition, if the parties fail to close on
or before December 31, 2000 a stock purchase agreement pursuant to which CSI or
an affiliate of CSI purchases approximately 4.99% of CONVERGENT's Common Stock,
the terms of this Agreement shall be subject to renegotiation at the option of
CSI. CSI must exercise such option in writing on or before January 31, 2001.
Senior management of the parties, initially Glenn E. Montgomery, Jr., CEO of
CONVERGENT and Larry Thomas, Vice President of CSI, shall meet within ten days
of the exercise of such option. If the Parties have failed to execute a
renegotiated agreement upon mutually acceptable terms and conditions within
twenty-five days after the exercise of such option, CSI may elect to terminate
this Agreement upon written notice to CONVERGENT. Upon such termination, and
except to the extent otherwise agreed by the Parties, all Work shall cease and
there shall be a full True-Up as of the date of such termination in accordance
with Section 7.1. If no early termination occurs, at least 90 days prior to the
end of the initial two-year term of this Agreement, CSI shall notify CONVERGENT
if it intends not to renew, extend, or renegotiate the terms of this Agreement.
Absent such notice, the Parties shall negotiate in good faith to renew or
extend this Agreement or negotiate a new agreement for services provided by
CONVERGENT.

7.2     All license rights granted but not paid in full by CSI shall cease
upon the expiration of this Agreement. Within fifteen (15) days after such
expiration, CSI shall certify to CONVERGENT in writing that the original and
all copies of the Custom Software, Documentation and Third-Party Software not
paid for in full by CSI, in any form, have been destroyed.

8.      CONFIDENTIALITY OF INFORMATION

8.1     The Parties acknowledge that in the course of this Agreement they will
have access to, and/or will be in possession of, Confidential Information of
the other. "Confidential Information" shall mean information regarded by the
disclosing Party as confidential, including, but not limited to, information
relating to its past, present, or future research, development, or business
affairs; future project purchases; any proprietary products, materials, or
methodologies; all items prepared for and submitted to the receiving Party in
connection with Work performed under this Agreement, including drafts and
associated material; and or any other information marked or, in the case of
information verbally disclosed, verbally designated as confidential at the time
of disclosure by the disclosing

Party and is reduced to a written summary marked in accordance with the verbal
disclosure and delivered to the other Party within thirty (30) days after
disclosure.

8.2     Each Party shall hold in confidence, in the same manner as it holds its
own Confidential Information of like kind, all Confidential Information of the
other to which it may have access hereunder. Access to Confidential Information
shall be restricted to those of each Party's personnel, subcontractors and
other agents with a need to know and engaged in a permitted use. Both Parties
agree that their respective personnel, subcontractors, agents, and
representatives who are given access to Confidential Information relating to
this Agreement will be made aware of this Article and will understand that they
are bound by this Article. Deliverable Products marked confidential shall
neither be exhibited nor distributed in any way to parties external to this
Agreement.

8.3     The foregoing shall not prohibit or limit either Party's use of
information including, but not limited to, ideas, concepts, know-how,
techniques, and methodologies which (i) are or become generally available to
and known by the public (other than as a result of an unpermitted disclosure
directly or indirectly by the receiving Party hereunder or its agents,
representatives, or advisors), (ii) is or becomes available to it on a
nonconfidential basis from a source other than the disclosing Party or its
affiliates, advisors, agents, or representatives, provided that such source is
not and was not bound by a confidentiality agreement with or other obligation
of secrecy to the disclosing Party, (iii) has already been or is hereafter
independently acquired or developed by it without violating any
confidentiality agreement or other obligation of secrecy to the disclosing
Party, or (iv) is required by law or regulation to be disclosed, provided,
however, that it shall give the disclosing Party reasonable advance notice of
such requirements so that the disclosing Party may seek appropriate legal
relief against such disclosure.

8.4     The Parties hereto agree and acknowledge that any such Confidential
Information shall be considered for all purposes confidential and privileged
information under any local, state, or federal law and such Confidential
Information shall not be released pursuant to any local, state, or federal act,
law, or statute concerning "freedom of information."

8.5     This Article shall survive termination or expiration of this Agreement
for any reason for a period of three (3) years, except that the nondisclosure
obligations and restrictions on use with respect to any Confidential
Information that constitutes a trade secret shall continue in effect for so
long as the Confidential Information remains a trade secret.

8.6     The Parties acknowledge and agree that the provisions of this Article
are essential to the other Party and are reasonable and necessary to protect
the legitimate interests of the other Party and that the damages sustained by a
Party as a result of a breach of the agreements contained herein will subject a
Party to immediate, irreparable harm and damage, the amount of which, although
substantial, could not be reasonably ascertainable, and that recovery of
damages at law will not be an adequate remedy. Therefore, the Parties agree
that the other Party, in addition to any other remedy it may have under this
Agreement or at law, shall be entitled to seek injunctive and other equitable
relief to prevent or curtail any breach of any provision of this Article. The
Parties waive any right to the posting of a bond in the event of an issuance of
a temporary restraining order, preliminary injunction, or permanent injunction
upon the issuance of said order by a court of competent jurisdiction.

10.      NON-SOLICITATION OF EMPLOYEES

10.1     The Parties agree that they will not, during the term of this
Agreement and for a period continuing for 24 months after the expiration or
termination of this Agreement, for any reason, directly or indirectly, solicit,
influence, entice, or encourage any person who is then or had been within one
(1) year of such action an employee to cease his or her relationship with that
Party, or otherwise interfere with, disrupt, or attempt to disrupt any past,
present, or prospective relationship, contractual or otherwise, between the
other Party and any of its employees.

10.2     The Parties further agree that they will not, during the term of this
Agreement and for a period continuing for 24 months thereafter, hire or attempt
to hire, whether as an employee, consultant, or otherwise, any person who was
employed by the other Party at any time during the term of this Agreement.

10.3     Both Parties acknowledge and agree that the provisions of this Article
are essential to them and are reasonable and necessary to protect the
legitimate interests of each Party and that the damages sustained by either
Party as a result of a breach of the agreements contained herein will subject
them to immediate, irreparable harm and damage, the amount of which, although
substantial, could not be reasonably ascertainable, and that recovery of
damages at law will not be an adequate remedy. Therefore, the Parties agree
that, in addition to any other remedy they may have under this Agreement or at
law, each shall be entitled to seek injunctive and other equitable relief to
prevent or curtail any breach of any provision of this Article. Both Parties
waive any right to the posting of a bond in the event of an issuance of a
temporary restraining order, preliminary injunction, or permanent injunction
upon the issuance of said order by a court of competent jurisdiction.

10.4     This Article shall survive termination or expiration of this Agreement
for any reason.

10.5     If the scope of any restriction contained in this Article is too broad
to permit enforcement of such restriction to its fullest extent, then such
restriction shall be enforced to the maximum extent permitted by law and each
Party hereby consents and agrees that the scope may be judicially modified in
any proceeding brought to enforce such restriction.

10.6     This Article shall not be applicable to retirees or persons
involuntarily separated or involuntarily redeployed.

this Agreement.

11.2    CSI and CONVERGENT reserve the right to subsequently amend this

17.      LIMIT OF LIABILITY

Both Parties' liability with respect to Work provided under this Agreement

EARNINGS, LOSS OF PROFITS, LOSS OF INTEREST, JUDGMENTS, AWARDS, OR CONTRIBUTION

provision in Article 20, shall be that CONVERGENT will, pursuant to applicable

CONVERGENT is unable to cure such defects, as CSI's exclusive remedy,

EMPLOYEES BE LIABLE UNDER OR IN CONNECTION WITH THIS AGREEMENT UNDER ANY
THEORY OF TORT, CONTRACT, STRICT LIABILITY, OR OTHER LEGAL OR EQUITABLE THEORY
FOR LOST PROFITS, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES. This
limitation is not applicable to indemnification obligations with respect to
third party claims for patent, copyright, and trade secret infringement which
claims are covered by Article 20.

20.      PATENTS, TRADEMARKS AND TRADE SECRET INFRINGEMENT INDEMNITY

20.1     Notwithstanding any provision to the contrary contained in this
Agreement, CONVERGENT shall defend, as its expense, any action brought against
CSI to the extent that it is based upon a claim that any Hardware, Third Party
Software, Custom Software or Documentation, infringes a patent, copyright or
intellectual property right, or violates any third party trade secret or
proprietary right and shall pay all costs and damages finally awarded against
CSI, provided that CONVERGENT is given by CSI, (a) written notice within a
reasonable time after CSI is notified of any such action or claim; (b) any
reasonably requested information or assistance at the expense of CONVERGENT
(other than expenses associated with the time of CSI's employees); and (c) sole
authority to defend or settle the claim. In addition to the foregoing obligation
of defense and indemnification, CONVERGENT shall, to the extent that it is
permitted to do so, assign any intellectual property infringement and
indemnification rights it receives from third party Hardware providers, Third
Party Software providers, and third party Documentation providers.

20.2     If any such action is brought, or in CONVERGENT's opinion is likely to
be brought, then CONVERGENT may at its election (i) obtain for CSI the right
to continue using the Hardware, Third Party Software, Custom Software or
Documentation; (ii) replace or modify such items so that they become
noninfringing; or (iii) if such remedies are not reasonably available, accept
CSI's return of such items and grant CSI a refund for such items involved,
based upon its straight line depreciated value over the useful life of such
item.

20.3     CONVERGENT shall have no obligation under this Article to the extent
that the alleged infringement or violation is based upon the use by CSI,
without the prior written consent or direction of CONVERGENT, of the Hardware,
Third Party Software, Custom Software or Documentation in combination with
other hardware, software, or documentation not furnished by CONVERGENT, or from
CSI's modification of the Hardware, Third Party Software, Custom Software or
Documentation without the prior written consent or direction of CONVERGENT.

Parties and its respective successors and permitted assigns.

27.      DELAYS

not constitute a default hereunder or be a ground for termination of this
Agreement, or give rise to any claims for damage against either Party if such

Party of its Work shall be extended for a period of time equivalent to the time
attributable to such delay.

28.      SEVERABILITY

circumstance shall be declared invalid, illegal, or unenforceable, the
remainder of this Agreement shall be valid and enforceable to the extent
permitted by applicable law. In such event, the Parties shall use their best
efforts to replace the invalid or unenforceable provision with a provision
that, to the extent permitted by applicable law, achieves the purposes intended
under the invalid or unenforceable provision.

individuals to the project shall be open to inspection by CSI during normal

32.      ALTERNATE DISPUTE RESOLUTION (ADR)

32.1     If a dispute arises between the Parties relating to this Agreement,
the Parties agree to use the following procedure prior to either Party pursuing
other available remedies:

         (a)      A meeting shall be held promptly between the Parties,
                  attended by individuals with decision-making authority
                  regarding the dispute, to attempt in good faith to negotiate
                  a resolution of the dispute.

         (b)      If, within twenty-one (21) days after such meeting, the
                  Parties have not succeeded in negotiating a resolution of the
                  dispute, the matter will be escalated to senior management of
                  the parties, initially Glenn E. Montgomery, Jr., CEO of
                  CONVERGENT and Larry Thomas, President of CSI.

         (c)      If, within thirty (30) days after such meeting, the Parties
                  have not succeeded in negotiating a resolution of the dispute,
                  they will jointly appoint a mutually acceptable neutral
                  person not affiliated with either of the Parties (the
                  "Neutral") to act as a mediator. If the Parties are unable to
                  agree on the Neutral within twenty (20) days, they shall seek
                  assistance in such regard from the CPR Institute for Dispute
                  Resolutions ("CPR"). The fees of the Neutral and all other
                  common fees and expenses shall be shared equally by the
                  Parties.

         (d)      The mediation may proceed in accordance with CPR's Model
                  Procedure for Mediation of Business disputes, or the Parties
                  may mutually establish their own procedure.

         (e)      The Parties shall pursue mediation in good faith and in a
                  timely manner. In the event the mediation does not result in
                  resolution of the dispute within sixty (60) days, then, upon
                  seven (7) days written notice to the other Party, either
                  Party may suggest another form of ADR, e.g., a mini-trial or
                  summary jury trial, or may pursue other available remedies.

32.2     All ADR proceedings shall be strictly confidential and used solely for
the purposes of settlement. Any materials prepared by one Party for the ADR
proceedings shall not be used as evidence by the other Party in any subsequent
litigation; provided, however, the underlying facts supporting such materials
may be subject to discovery.

32.3     Each Party shall, except as otherwise provided herein, be responsible
for its expenses, including legal fees, incurred in the course of any
arbitration proceedings. The fees of the Neutral arbitrator shall be divided
evenly between the Parties.

32.4     CONVERGENT shall carry on and be paid for the technical and management
services not in dispute and maintain the estimated schedule for Services during
any

arbitration or litigation proceedings, unless otherwise agreed by CONVERGENT or
CSI in writing.

32.5     Each Party fully understands its specific obligations under ADR
provisions of the Agreement. Neither Party considers such obligations to be
vague or in any way unenforceable, and neither Party will contend to the
contrary at any future time or in any future proceedings.

32.6     Neither Party shall issue any news release, public announcement, or
advertisement of any portion of the content of this Agreement without the prior
written consent of the other Party.

32.7     If CSI issues a purchase order, memorandum or other instruments
covering the goods or services provided under this Agreement, it is agreed that
such document is for CSI's internal purposes only unless it is accepted in
writing by CONVERGENT, in which case all terms and conditions contained therein
which are additional to or inconsistent with this Agreement shall be of no
force and effect. The Agreement shall not be varied other than by an instrument
in writing of subsequent date hereto, executed by the duly authorized
representatives of both Parties.

32.8     IN WITNESS WHEREOF, the Parties have executed this Agreement as of the
Effective Date.
