NEITHER THIS WARRANT NOR ANY OF THE SECURITIES ISSUABLE UPON EXERCISE HEREOF
HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
"SECURITIES ACT"), OR ANY STATE SECURITIES LAWS. NO TRANSFER OF THIS WARRANT OR
OF THE SECURITIES ISSUABLE UPON EXERCISE HEREOF SHALL BE VALID OR EFFECTIVE
UNLESS (A) SUCH TRANSFER IS MADE PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES
LAWS OR (B) THE HOLDER HEREOF SHALL DELIVER TO THE COMPANY AN OPINION OF COUNSEL
IN FORM AND SUBSTANCE REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS
EXEMPT FROM THE REGISTRATION OR QUALIFICATION REQUIREMENTS OF THE SECURITIES ACT
AND ANY APPLICABLE STATE SECURITIES LAWS.

WARRANT NO. C-2-1                                                MARCH 30, 2001

                               USDATA CORPORATION

                   SERIES C-2 PREFERRED STOCK PURCHASE WARRANT

Subject to the terms and conditions set forth herein, USDATA Corporation, a
Delaware corporation (the "Company"), hereby grants to SCP Private Equity
Partners II, L.P. ("SCP"), a Delaware limited partnership, or its registered
assigns or transferees (SCP and each such assign or transferee being referred to
herein as a "Holder" and collectively as the "Holders") the right to purchase,
at any time and from time to time after the date hereof and until 5:00 p.m.
(Eastern Standard Time) on March 30, 2011 (the "Expiration Date"), 75,000 fully
paid and non-assessable shares of the Company's Series C-2 Preferred Stock, par
value $0.01 per share (the "Series C Shares"), at a purchase price per share of
$40.00 (the "Exercise Price").

1. Exercise of Warrant.

1.1 Exercise. Subject to adjustment as provided in Section 3 hereof, the rights
represented by this Warrant are exercisable, in whole or in part, on any
business day (the "Exercise Date") and on or before the Expiration Date, at the
Exercise Price per share of the Series C Shares issuable hereunder (hereinafter,
"Warrant Shares"); provided, however that 50,500 of the Warrant Shares shall not
become exercisable until the earlier of stockholder approval of the transactions
contemplated hereby or May 31, 2001. Unless this Warrant is exercised in
accordance with Section 1.2 hereof, the Exercise Price shall be payable in cash,
or by certified or official bank check.

1.2 Net Issue Election. The Holder may elect to receive, without the payment by
the Holder of any additional consideration, either (x) in the event of any
liquidation, dissolution or winding up of the Company (whether actual or deemed
to have occurred pursuant to Section 3.c of the Company's Certificate of
Designation for Series C-1 Preferred Stock and Series C-2 Preferred Stock), the
Net Liquidation Value of this Warrant (as hereinafter defined) or (y) shares
equal to the Net Value of this Warrant (as hereinafter defined), or in either
case any portion hereof, by the surrender of this Warrant or such portion to the
Company, with the Notice of Net Issue Election in the form of Annex C hereto
duly executed, at the office of the Company. Thereupon, the Company shall issue
to the Holder the Net Liquidation Value of this Warrant (or portion thereof), in
the case of a net exercise pursuant to clause (x) or such number of fully paid
and nonassessable Series C Shares as is computed using the following formula, in
the case of a net exercise pursuant to clause (y):

                                   X = Y(A-B)
                                       ------
                                        A

where     X = the number of shares to be issued to the holder pursuant to this
          Section 1.2.

<PAGE>   2

          Y = the number of shares covered by this Warrant in respect of which
          the net issue election is made pursuant to this Section 1.2.

          A = the fair market value of one Series C Share, which shall be deemed
          to equal the fair market value of one share of the Company's Common
          Stock, as determined in accordance with the provisions of this Section
          1.2; provided, however, that if each Series C Share is then
          convertible into more than or less than one share of the Company's
          Common Stock, then the fair market value of each Series C Share shall
          be deemed to equal the fair market value of one share of the Company's
          Common Stock multiplied by the number of shares of the Company's
          Common Stock into which each Series C Share is then convertible.

          B = the Exercise Price in effect under this Warrant at the time the
          net issue election is made pursuant to this Section 1.2.

For purposes of this Section 1.2, the "fair market value" per share of the
Company's Common Stock shall mean:

(a) If the Company's Common Stock is traded on a national securities exchange or
admitted to unlisted trading privileges on such an exchange, or is listed on the
National Market (the "National Market") of the National Association of
Securities Dealers Automated Quotations System (the "NASDAQ"), the fair market
value shall be the average of the last reported sale prices of the Company's
Common Stock on such exchange or on the National Market over the five (5)
consecutive trading days immediately preceding the effective date of exercise of
the net issue election or if the last reported sale price information is not
available for such days, the average of the mean of the closing bid and asked
prices for such days on such exchange or on the National Market;

(b) If the Company's Common Stock is not listed or admitted to unlisted trading
privileges, the fair market value shall be the average of the mean of the last
bid and asked prices reported over the five (5) consecutive Business Days
immediately preceding the effective date of exercise of the net issue election
(1) by the NASDAQ or (2) if reports are unavailable under clause (1) above, by
the National Quotation Bureau Incorporated; and

(c) If the Company's Common Stock is not so listed or admitted to unlisted
trading privileges and bid and ask prices are not reported, the fair market
value shall be the price per share which the Company could obtain from a willing
buyer for shares sold by the Company from authorized but unissued shares, as
such price shall be determined by mutual agreement of the Company and the holder
of this Warrant. If the holder of this Warrant and the Company are unable to
agree on such fair market value, the holder of this Warrant and the Company
shall each select an independent and nationally-recognized investment banking
firm and such selected firms shall select another such firm to appraise the fair
market value of the Warrant and to perform the computations involved. The
determination of such investment banking firm shall be binding upon the Company,
the holder of this Warrant and any other holder of Warrants or Warrant Shares in
connection with any transaction occurring at the time of such determination. All
expenses of such investment banking firm shall be borne equally by the Company
and the Holder of this Warrant. In all cases, the determination of fair market
value shall be made without consideration of the lack of a liquid public market
for the Common Stock and without consideration of any "control premium" or any
discount for holding less than a majority or controlling interest of the
outstanding Common Stock.

For purposes of this Section 1.2, the term "Net Liquidation Value" of this
Warrant, or portion thereof, shall mean the amount payable to the holders of
Series C Shares (with respect to the number of Series C Shares covered by this
Warrant in respect of which the net issue election is made pursuant to clause
(x) of Section 1.2, and assuming, for purposes of calculating the "Net
Liquidation Value, that such Series C Shares are issued and outstanding) as a
result of or in connection with any liquidation, dissolution or winding up of
the Company pursuant to Section 3 of the Company's Certificate of Designation
for Series C-1 Preferred Stock and Series C-2 Preferred Stock (whether actual or
deemed to have occurred pursuant to Section 3.c thereof) less the Exercise Price
of such Series C Shares.

1.3 Automatic Exercise Prior to Expiration. If not earlier exercised, this
Warrant shall be deemed to have been exercised in full pursuant to Section 1.2
immediately prior to the expiration hereof, and upon such deemed exercise, and
without any further act or deed of the holder hereof or any other person or
entity, the Company shall issue to the Holder hereof the number of fully paid
and non-assessable Series C Shares to which such holder would be entitled under
Section 1.2.

1.4 Delivery of Certificate. Upon surrender of this Warrant with (a) a duly
executed Notice of Exercise in the form of Annex A attached hereto, together
with payment of the Exercise Price for the Warrant Shares purchased, or (b) a

                                        2
<PAGE>   3

duly executed Notice of Net Issue Election in the form of Annex C hereto, at the
Company's principal executive offices presently located at 2435 North Central
Expressway, Richardson, Texas, 75080, or at such other address as the Company
shall have advised the holder in writing (the "Designated Office"), the Holder
shall be entitled to receive a certificate or certificates for the Warrant
Shares so purchased. The Company agrees that the Warrant Shares shall be deemed
to have been issued to the holder as of the close of business on the date on
which this Warrant shall have been surrendered together with (x) the Notice of
Exercise and payment for such Warrant Shares or (y) the Notice of Net Issue
Election.

2. Transfer; Issuance of Stock Certificates; Restrictive Legends.

2.1 Transfer. Subject to compliance with the restrictions on transfer set forth
in this Section 2, each transfer of this Warrant and all rights hereunder, in
whole or in part, shall be registered on the books of the Company to be
maintained for such purpose, upon surrender of this Warrant at the Designated
Office, together with a written assignment of this Warrant in the form of Annex
B attached hereto duly executed by the holder or its agent or attorney. Upon
such surrender and delivery, the Company shall execute and deliver a new Warrant
or Warrants in the name of the assignee or assignees and in the denominations
specified in such instrument of assignment, and shall issue to the assignor a
new Warrant evidencing the portion of this Warrant not so assigned, if any. A
Warrant, if properly assigned in compliance with the provisions hereof, may be
exercised by the new holder for the purchase of Warrant Shares without having a
new Warrant issued. Prior to due presentment for registration of transfer
thereof, the Company may deem and treat the registered holder of this Warrant as
the absolute owner hereof (notwithstanding any notations of ownership or writing
thereon made by anyone other than a duly authorized officer of the Company) for
all purposes and shall not be affected by any notice to the contrary. All
Warrants issued upon any assignment of Warrants shall be the valid obligations
of the Company, evidencing the same rights, and entitled to the same benefits as
the Warrants surrendered upon such registration of transfer or exchange.

2.2 Stock Certificates. Certificates for the Warrant Shares shall be delivered
to the Holder within a reasonable time after the rights represented by this
Warrant shall have been exercised pursuant to Section 1, and a new Warrant
representing the Series C Shares, if any, with respect to which this Warrant
shall not then have been exercised shall also be issued to the Holder within
such time. The issuance of certificates for Warrant Shares upon the exercise of
this Warrant shall be made without charge to the Holder hereof including,
without limitation, any documentary, stamp or similar tax that may be payable in
respect thereof; provided, however, that the Company shall not be required to
pay any income tax to which the Holder hereof may be subject in connection with
the issuance of this Warrant or the Warrant Shares; and provided further, that
if Warrant Shares are to be delivered in a name other than the name of the
Holder hereof representing any Warrant being exercised, then no such delivery
shall be made unless the person requiring the same has paid to the Company the
amount of transfer taxes or charges incident thereto, if any.

2.3 Restrictive Legends.

(a) Except as otherwise provided in this Section 2, each certificate for Warrant
Shares initially issued upon the exercise of this Warrant, and each certificate
for Warrant Shares issued to any subsequent transferee of any such certificate,
shall be stamped or otherwise imprinted with a legend in substantially the
following form:

         "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
         ANY STATE SECURITIES LAW. NO TRANSFER OF THE SHARES REPRESENTED BY THIS
         CERTIFICATE OR ISSUED UPON CONVERSION OF SUCH SHARES SHALL BE VALID OR
         EFFECTIVE UNLESS (A) SUCH TRANSFER IS MADE PURSUANT TO AN EFFECTIVE
         REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND IN COMPLIANCE WITH
         ANY APPLICABLE STATE SECURITIES LAWS, OR (B) THE HOLDER SHALL DELIVER
         TO THE COMPANY AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY
         ACCEPTABLE TO THE COMPANY THAT SUCH PROPOSED TRANSFER IS EXEMPT FROM
         THE REGISTRATION OR QUALIFICATION REQUIREMENTS OF THE SECURITIES ACT
         AND ANY APPLICABLE STATE SECURITIES LAWS."

                                        3
<PAGE>   4

(b) Except as otherwise provided in this Section 2, each Warrant shall be
stamped or otherwise imprinted with a legend in substantially the following
form:

         "NEITHER THIS WARRANT NOR ANY OF THE SECURITIES ISSUABLE UPON EXERCISE
         HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
         AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS. NO
         TRANSFER OF THIS WARRANT OR OF THE SECURITIES ISSUABLE UPON EXERCISE
         HEREOF SHALL BE VALID OR EFFECTIVE UNLESS (A) SUCH TRANSFER IS MADE
         PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
         ACT AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS, OR (B)
         THE HOLDER SHALL DELIVER TO THE COMPANY AN OPINION OF COUNSEL IN FORM
         AND SUBSTANCE REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER
         IS EXEMPT FROM THE REGISTRATION OR QUALIFICATION REQUIREMENTS OF THE
         SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS."

Notwithstanding the foregoing, the legend requirements of this Section 2.3 shall
terminate as to any particular Warrant or Warrant Share when the Company shall
have received from the Holder thereof an opinion of counsel in form and
substance reasonably acceptable to the Company that such legend is not required
in order to ensure compliance with the Securities Act and applicable state
securities laws. Whenever the restrictions imposed by this Section 2.3 shall
terminate, the holder hereof or of Warrant Shares, as the case may be, shall be
entitled to receive from the Company without cost to such holder a new Warrant
or certificate for Warrant Shares of like tenor, as the case may be, without
such restrictive legend.

3. Adjustment of Number of Shares; Exercise Price; Nature of Securities Issuable
Upon Exercise of Warrants.

3.1 Exercise Price; Adjustment of Number of Shares. The Exercise Price set forth
in Section 1 hereof and the number of shares purchasable hereunder shall be
subject to adjustment from time to time as hereinafter provided.

3.1.1 Merger, Sale of Assets, etc. If at any time while this Warrant, or any
portion thereof, is outstanding and unexpired there shall be a reorganization
(other than a combination, reclassification, exchange, or subdivision of shares
as provided in Sections 3.1.2 and 3.1.3), merger or consolidation of the Company
with or into another corporation in which the Company is not the surviving
entity, or a merger in which the Company is the surviving entity but the shares
of the Company's capital stock outstanding immediately prior to the merger are
converted by virtue of the merger into other property, whether in the form of
securities, cash, or otherwise, or a sale or transfer of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such reorganization, merger, consolidation, sale or transfer,
lawful provision shall be made so that the holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified herein and upon payment of the Exercise Price then in effect,
the number of shares of stock or other securities or cash or property of the
successor corporation resulting from such reorganization, merger, consolidation,
sale or transfer that a holder of the shares deliverable upon exercise of this
Warrant would have been entitled to receive in such reorganization,
consolidation, merger, sale or transfer if this Warrant had been exercised
immediately before such reorganization, consolidation, merger, sale or transfer,
all subject to further adjustment as provided in this Section 3. The foregoing
provisions of this Section 3.1.1 shall similarly apply to successive
reorganizations, consolidations, mergers, sales and transfers and to the stock
and securities of any other corporation that are at the time receivable upon the
exercise of this Warrant. If the per share consideration payable to the holder
hereof for shares in connection with any such transaction is in a form other
than cash or securities, then the value of such consideration shall be
determined in good faith by the Company's Board of Directors. In all events,
appropriate adjustment shall be made in the application of the provisions of
this Warrant with respect to the rights and interests of the holder hereof after
the transaction, to the end that the provisions of this Warrant shall be
applicable after that event, as near as reasonably may be, in relation to any
shares or other property deliverable after that event upon exercise of this
Warrant.

3.1.2 Reclassification, etc. If the Company, at any time while this Warrant, or
any portion thereof, remains outstanding and unexpired, shall, by the
reclassification or exchange of securities or otherwise, change any of the
securities as to which purchase rights under this Warrant exist into the same or
a different number of securities of any other

                                        4
<PAGE>   5

class or classes, this Warrant shall thereafter represent the right to acquire
such number and kind of securities as would have been issuable as the result of
such change with respect to the securities that were subject to the purchase
rights under this Warrant immediately prior to such reclassification, exchange,
or other change and the Exercise Price therefor shall be appropriately adjusted,
all subject to further adjustment as provided in this Section 3.

3.1.3 Stock Splits, Stock Dividends and Reverse Stock Splits. In case at any
time the Company shall split or subdivide the outstanding shares of Series C
Shares into a greater number of shares, or shall declare and pay any stock
dividend with respect to its outstanding stock that has the effect of increasing
the number of outstanding shares of Series C Shares, the Exercise Price in
effect immediately prior to such subdivision or stock dividend shall be
proportionately reduced and the number of Warrant Shares purchasable pursuant to
this Warrant immediately prior to such subdivision or stock dividend shall be
proportionately increased, and conversely, in case at any time the Company shall
combine its outstanding shares of Series C Shares into a smaller number of
shares, the Exercise Price in effect immediately prior to such combination shall
be proportionately increased and the number of Warrant Shares purchasable upon
the exercise of this Warrant immediately prior to such combination shall be
proportionately reduced.

3.1.4 Adjustments for Dividends in Stock or Other Securities of Property. If
while this Warrant, or any portion hereof, remains outstanding and unexpired the
holders of Series C Shares shall have received, or, on or after the record date
fixed for the determination of eligible stockholders, shall have become entitled
to receive, without payment therefor, other or additional stock or other
securities or property (other than cash) of the Company by way of dividend, then
and in each case, this Warrant shall represent the right to acquire, in addition
to the number of shares of the security receivable upon exercise of this
Warrant, and without payment of any additional consideration therefor, the
amount of such other or additional stock or other securities or property of the
Company that such holder would hold on the date of such exercise had it been the
holder of record of the security receivable upon exercise of this Warrant on the
date hereof and had thereafter, during the period from the date hereof to and
including the date of such exercise, retained such shares and/or all other
additional stock available by it as aforesaid during such period, giving effect
to all adjustments called for during such period by the provisions of this
Section 3.

3.2 Timing of Exercise Price Adjustment. No adjustment of the Exercise Price
shall be made unless such adjustment would require an increase or decrease of at
least $0.0001 in such price; provided that any adjustments which by reason of
this Section 3.2 are not required to be made shall be carried forward and shall
be made at the time of and together with the next subsequent adjustment which,
together with any adjustment(s) so carried forward, shall require an increase or
decrease of at least $0.0001 in the Exercise Price then in effect hereunder.

3.3 Adjustment Certificate. In each case of an adjustment in the Exercise Price,
number of Warrant Shares or other stock, securities or property receivable upon
the exercise of this Warrant, the Company shall compute and prepare a
certificate setting forth such adjustment and showing in detail the facts upon
which such adjustment is based, including a statement of (i) the number of
Series C Shares outstanding or deemed to be outstanding, (ii) the adjusted
Exercise Price and (iii) the number of Warrant Shares issuable upon exercise of
this Warrant. The Company will forthwith mail a copy of each such certificate to
the holder hereof.

4. Registration; Exchange and Replacement of Warrant; Reservation of Shares. The
Company shall keep at the Designated Office a register in which the Company
shall provide for the registration, transfer and exchange of this Warrant. The
Company shall not at any time, except upon the dissolution, liquidation or
winding-up of the Company, close such register so as to result in preventing or
delaying the exercise or transfer of this Warrant.

The Company may deem and treat the person in whose name this Warrant is
registered as the holder and owner hereof for all purposes and shall not be
affected by any notice to the contrary, until presentation of this Warrant for
registration or transfer as provided in this Section 4.

Upon receipt by the Company of evidence reasonably satisfactory to it of the
loss, theft, destruction or mutilation of this Warrant and (in case of loss,
theft or destruction) of indemnity satisfactory to it, and (in the case of
mutilation) upon surrender and cancellation of this Warrant, the Company will
(in the absence of notice to the Company that the Warrant has been acquired by a
bona fide purchaser) make and deliver a new Warrant of like tenor, in lieu of
this Warrant without requiring the posting of any bond or the giving of any
security.

The Company shall at all times reserve and keep available out of its authorized
shares of Series C Shares, solely for the purpose of issuance upon the exercise
of this Warrant, such number of shares of Series C Shares as shall be

                                        5
<PAGE>   6

issuable upon the exercise hereof. The Company covenants and agrees that, upon
exercise of this Warrant and payment of the Exercise Price therefor, if
applicable, all Warrant Shares issuable upon such exercise shall be duly and
validly issued, fully paid and non-assessable.

5. Fractional Warrants and Fractional Shares. If the number of Warrant Shares
purchasable upon the exercise of this Warrant is adjusted pursuant to Section 3
hereof, the Company shall nevertheless not be required to issue fractions of
shares, upon exercise of this Warrant or otherwise, or to distribute
certificates that evidence fractional shares. With respect to any fraction of a
share called for upon any exercise hereof, the Company shall pay to the holder
an amount in cash equal to such fraction multiplied by the current market value
of such fractional share as may be prescribed by the Board of Directors of the
Company.

6. Warrant Holders Not Deemed Stockholders. No holder of this Warrant shall, as
such, be entitled to vote or to receive dividends or be deemed the holder of
Warrant Shares that may at any time be issuable upon exercise of this Warrant
for any purpose whatsoever, nor shall anything contained herein be construed to
confer upon the holder of this Warrant, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to shareholders at any meeting thereof, or for the
election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action (whether
upon any recapitalization, issue or reclassification of stock, change of par
value or change of stock to no par value, consolidation, merger or conveyance or
otherwise), or to receive notice of meetings, or to receive dividends or
subscription rights, until such holder shall have exercised this Warrant and
been issued Warrant Shares in accordance with the provisions hereof.

7. Notices. All notices, requests, consents and other communications hereunder
shall be in writing and shall be deemed to have been duly made when delivered
personally, or mailed by registered or certified mail, return receipt requested,
or telecopied or telexed and confirmed in writing and delivered personally or
mailed by registered or certified mail, return receipt requested (a) if to the
holder of this Warrant, to the address of such holder as shown on the books of
the Company, or (b) if to the Company, to the address set forth in Section 1.4
of this Warrant; or at such other address as the holder or the Company may
hereafter have advised the other.

8. Successors. All the covenants, agreements, representations and warranties
contained in this Warrant shall bind the parties hereto and their respective
heirs, executors, administrators, distributees, successors, assigns and
transferees.

9. Law Governing. This Warrant shall be construed and enforced in accordance
with, and governed by, the laws of the State of Delaware (not including the
choice of law rules thereof) regardless of the jurisdiction of creation or
domicile of the Company or its successors or of the holder at any time hereof.

10. Entire Agreement; Amendments and Waivers. This Warrant sets forth the entire
understanding of the parties with respect to the transactions contemplated
hereby. The failure of any party to seek redress for the violation or to insist
upon the strict performance of any term of this Warrant shall not constitute a
waiver of such term and such party shall be entitled to enforce such term
without regard to such forbearance. This Warrant may be amended, and any breach
of or compliance with any covenant, agreement, warranty or representation may be
waived, only if the Company has obtained the written consent or written waiver
of the holder, and then such consent or waiver shall be effective only in the
specific instance and for the specific purpose for which given.

11. Severability; Headings. If any term of this Warrant as applied to any person
or to any circumstance is prohibited, void, invalid or unenforceable in any
jurisdiction, such term shall, as to such jurisdiction, be ineffective to the
extent of such prohibition or invalidity without in any way affecting any other
term of this Warrant or affecting the validity or enforceability of this Warrant
or of such provision in any other jurisdiction. The Section headings in this
Warrant have been inserted for purposes of convenience only and shall have no
substantive effect.

         (a) Upon the request of the Holders of 25% of the Registrable
Securities then outstanding, the Company shall prepare and, not later than 30
days following such request, shall file with the SEC a Shelf Registration
Statement with respect to resales of the Registrable Securities from time to
time in accordance with the methods of distribution elected by the Holders of
the Registrable Securities and set forth in such Shelf Registration Statement

supplement or amend the Shelf Registration Statement if required by the rules,
regulations or instructions applicable to the registration form used by the
Company for the Shelf Registration Statement, if required by the Act, the 1934
Act or the SEC.

         (b) The Company shall keep the Shelf Registration Statement
continuously effective under the Act in order to permit the prospectus forming a
part thereof to be usable by all Holders until the earliest of (i) the fifth
anniversary of the date hereof, (ii) the date as of which all Registrable

<PAGE>   4

continuously effective for the Shelf Registration Period; (ii) subject to

supplement, and as so supplemented to be filed pursuant to Rule 424 (or any
similar provisions then in force) under the Act; and (iii) comply in all
material respects with the provisions of the Act with respect to the disposition
of all securities covered by the Shelf Registration Statement during the

         (c) The Company may suspend the use of the prospectus forming a part of
the Shelf Registration Statement for two periods not to exceed an aggregate of
60 days in any twelve-month period for valid business reasons, to be determined
by the Company in its reasonable judgment (not including avoidance of the
Company's obligations hereunder), including, without limitation, the acquisition
or divestiture of assets, public filings with the SEC, pending corporate
developments and similar events. The Company shall provide written notice to the
Holders of any such suspension.

         1.3 COMPANY REGISTRATION. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for stockholders other than the Holders) any securities under the
Act in connection with the public offering of such securities solely for cash
for its own account (other than a registration relating solely to the sale of
securities to participants in a Company stock plan, a registration on Form S-4
(or its successor) relating to an offering of shares in connection with any
acquisition of any entity or business, a registration on any form which does not
include substantially the same information as would be required to be included
in a registration statement covering the sale of the Registrable Securities or a
registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities or exercise of warrants which are
also being registered) and the Registrable Securities have not theretofore been
included in a Shelf Registration Statement pursuant to Section 1.2 that remains
effective, the Company shall, at such time, promptly give each Holder written
notice of such registration. Upon the written request of each Holder given
within 20 days after mailing of such notice by the Company, the Company shall,
subject to the provisions of Section 1.8, cause to be registered under the Act
all of the Registrable Securities that each such Holder has requested to be
registered. The obligations of the Company under this Section 1.3 with respect
to any particular offering may be waived at any time upon the written consent of
Holders of a majority of the outstanding Registrable Securities. The right of
any Holder to request inclusion of Registrable Securities held by it in any
registration pursuant to this Section 1.3 shall terminate if all shares of
Registrable Securities held or entitled to be held upon conversion by such
Holder are eligible to be sold under Rule 144 under the Act during any 90-day
period. In any event, such right shall terminate on the fifth anniversary of the
date hereof.

         1.4 OBLIGATIONS OF THE COMPANY. Whenever required under this Section 1
to effect the registration of any Registrable Securities, the Company shall, in
a reasonable amount of time and as promptly as possible:

         (a) prepare and file with the SEC a registration statement with respect
to such Registrable Securities and use its best efforts to cause such
registration statement to become

                                       4
<PAGE>   5

effective, and in the case of a registration under Section 1.14 hereof, upon the
request of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective for a period of up to 120
days or, if earlier, until the distribution contemplated in such registration
statement has been completed; provided, however, that such 120-day period shall
be extended for a period of time equal to the period the Holder refrains from
selling any securities included in such registration at the request of an
underwriter of Common Stock (or other securities) of the Company;

         (b) prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement;

         (c) furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them;

         (d) use its best efforts to register and qualify the securities covered
by such registration statement under such other securities or Blue Sky laws of
such jurisdictions as shall be reasonably requested by the Holders; provided,
however, that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions in which it is not, at
the time, so qualified or otherwise subject itself to general taxation in any
such states or jurisdictions;

         (e) in the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering, it being understood and
agreed that each Holder participating in such underwriting shall also enter into
and perform its obligations under such an agreement;

         (f) notify each Holder of Registrable Securities covered by such
registration statement in writing at any time when a prospectus relating thereto
is required to be delivered under the Act 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 not misleading in the light of the circumstances then existing;

         (g) cause all such Registrable Securities registered pursuant hereunder
to be listed on each securities exchange on which similar securities issued by
the Company are then listed;

         (h) provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration;

                                       5
<PAGE>   6

         (i) use its best efforts to obtain the withdrawal of any order
suspending the effectiveness of any such registration statement or the lifting
of any suspension of the qualification (or exemption from qualification) of any
of the Registrable Securities for offer or sale in any jurisdiction at the
earliest possible time; and

         (j) cooperate in all necessary respects with (A) counsel in preparation
of the customary legal opinions and (B) accountants in preparation of the
customary comfort letters.

         1.5 FURNISH INFORMATION. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

         1.6 EXPENSES OF SHELF REGISTRATION. All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 1.2, including
(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for the Company and the
reasonable fees and disbursements, which shall not exceed $25,000, of one
counsel for the selling Holders (to be selected by the Holders holding a
majority of the Registrable Securities) shall be borne and paid by the Company.

         1.7 EXPENSES OF COMPANY REGISTRATION. The Company shall bear and pay
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 1.3 for each Holder (which right may be assigned as provided
in Section 1.13), including (without limitation) all registration, filing, and
qualification fees, printers and accounting fees relating or apportionable
thereto and the fees and disbursements, which shall not exceed $25,000, of one
counsel for the selling Holders (to be selected by the holders of a majority of
the Registrable Securities to be registered), but excluding underwriting
discounts and commissions relating to Registrable Securities.

         1.8 UNDERWRITING REQUIREMENTS. In connection with any offering
involving an underwriting of shares of the Company's capital stock under Section
1.3, the Company shall not be required to include any of the Holders' securities
in such underwriting unless they accept the terms of the underwriting as agreed
upon between the Company and the underwriters selected by it (or by other
persons entitled to select the underwriters), and then only in such quantity as
the underwriters determine in their sole discretion will not, jeopardize the
success of the offering by the Company. If the total amount of securities,
including Registrable Securities, requested by stockholders to be included in
such offering exceeds the amount of securities sold other than by the Company
that the underwriters determine in their sole discretion is compatible with the
success of the offering, then the Company shall be required to include in the
offering only that number of such securities, including Registrable Securities,
which the underwriters determine in their sole discretion will not jeopardize
the success of the offering. The securities so included shall be apportioned (a)
first to the holders of the Series C Registrable Securities

                                       6
<PAGE>   7

selling Series C Registrable Securities pro rata according to the total amount
of Series C Registrable Securities entitled to be included therein owned by each
such selling holder; (b) second to the holders selling Series A and B
Registrable Securities pro rata according to the total amount of Series A and B
Registrable Securities entitled to be included therein owned by each such
selling holder and (c) third, to the extent determined by the underwriters to be
compatible with the offering, to other stockholders.

         1.9 DELAY OF REGISTRATION. No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1.

         1.10 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under this Section 1:

         (a) to the extent permitted by law, the Company will indemnify and hold
harmless each Holder, any underwriter (as defined in the Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the
meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein (for which such
statement of material fact is untrue in light of the circumstances under which
it was made) or any amendments or supplements thereto, (ii) 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 (iii) any
violation or alleged violation by the Company of the Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the Act, the
1934 Act or any state securities law; and the Company will pay to each such
Holder, underwriter or controlling person, promptly following delivery of an
invoice for such amounts incurred, any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection 1.10(a) shall not apply to: (x) amounts
paid in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld); (y) any such loss, claim, damage, liability, or
action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by any such Holder,
underwriter or controlling person; (z) any such loss, claim, damage, liability
or action to the extent that it arises out of or is based upon such Holder's or
underwriter's failure to deliver a copy of the registration statement or
prospectus or any amendments or supplements thereto;

         (b) to the extent permitted by law, each selling Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
has signed the registration statement, each person, if any, who controls the
Company within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, against any losses, claims, damages, or liabilities
(joint or several) to which any of the foregoing persons may become subject,
under the Act, the 1934 Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities

                                       7
<PAGE>   8

(or actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; and each such
Holder will pay, as incurred, any legal or other expenses reasonably incurred by
any person intended to be indemnified pursuant to this subsection 1.10(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 1.10(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; provided, that, in no event shall any indemnity under this subsection
1.10(b) exceed the gross proceeds from the offering received by such Holder;

         (c) promptly after receipt by an indemnified party under this Section
1.10 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 1.10, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.10, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.10;

         (d) if the indemnification provided for in this Section 1.10 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense 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 that resulted in such loss, liability, claim,
damage, or expense 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 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. In no event shall
any contribution by a Holder under this subsection 1.10(d) exceed the gross
proceeds from the offering received by

                                       8

such Holder. In no event shall a person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) be entitled
to contribution from any person or entity who was not guilty of fraudulent
misrepresentation;

         (e) notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control for such offering; and

         (f) the obligations of the Company and Holders under this Section 1.10
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

         1.11 REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. The Company shall
cause its Common Stock to continue to be registered under Sections 12(b) or
12(g) of the 1934 Act, shall comply in all respects with its reporting and
filing obligations under the 1934 Act, and shall not take any action or file any
document (whether or not permitted by the 1934 Act or the rules thereunder) to
terminate or suspend such registration or to terminate or suspend its reporting
and filing obligations under the 1934 Act. The Company shall take all reasonable
actions necessary to continue the listing or trading of its Common Stock on any
national securities exchange or the Automated Quotation System of the National
Association of Securities Dealers on which Common Stock is listed or traded, and
shall comply in all material respects with its reporting, filing and other
obligations under the bylaws or rules of such exchange or association. The
Company will furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144, the Act and the
1934 Act or that it qualifies as a registrant whose securities may be resold
pursuant to Form S-3 under the Act, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents as are
filed by the Company under the 1934 Act, and (iii) such other information as may
be reasonably requested in availing any Holder of any rule or regulation of the
SEC which permits the selling of any such securities without registration or
pursuant to such form.

         1.12 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company
to register Registrable Securities pursuant to this Section 1 may be assigned
(but only with all related obligations) by a Holder to (a) any partner or
retired partner of any holder which is a partnership, (b) any family member or
trust for the benefit of any individual holder, or (c) any transferee or
assignee who, after such assignment or transfer, holds at least 15% of the then
outstanding Registrable Securities, provided: (i) the Company is, within a
reasonable time after such transfer, furnished with written notice of the name
and address of such transferee or assignee and the securities with respect to
which such registration rights are being assigned; (ii) such transferee or
assignee agrees in writing to be bound by and subject to the terms and
conditions of this Agreement; and (iii) such assignment shall be effective only
if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Act.

         1.13 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the
date of this Agreement, the Company shall not, without the prior written consent
of the Holders

                                       9
<PAGE>   10

of a majority of the outstanding Registrable Securities then outstanding, enter
into any agreement with any holder or prospective holder of any securities of
the Company which would allow such holder or prospective holder to interfere
with or otherwise limit a Holder's registration rights under this Agreement.

         1.14 REQUEST FOR REGISTRATION.

         (a) If the Company shall at any time during the Shelf Registration
Period be ineligible to use Form S-3 or Form S-3 shall be for any reason
unavailable to register the Registrable Securities under the rules and
regulation of the SEC, and the duration of such ineligibility or unavailability
exceeds or is expected to exceed 60 days, the Holders shall have the right by a
written request from the Holders of a majority of the Registrable Securities
then outstanding to the Company, to require the Company to file a registration
statement under the Act covering the resales of at least 25% of the Registrable
Securities then outstanding (or a lesser percent if the anticipated aggregate
offering price, net of underwriting discounts and commissions, would exceed
$10,000,000), but in no event will the aggregate value of the shares to be
registered under such registration statement be less than $500,000. Upon its
receipt of such a written request, the Company shall given written notice of
such request to all Holders within ten days thereof. The Company shall file as
soon as practicable, and in any event within 90 days of the receipt of such
request, a registration statement under the Act covering resales of all
Registrable Securities which Holders request to be registered, subject to the
limitations of subsection 1.14(b).

         (b) If the Holders initiating the registration request hereunder (the
"Initiating Holders") intend to distribute the Registrable Securities covered by
their request by means of an underwriting, they shall so advise the Company as a
part of their request made pursuant to subsection 1.14(a) and the Company shall
include such information in the written notice referred to in subsection
1.14(a). The managing underwriter shall be selected by a majority in interest of
the Initiating Holders and shall be reasonably acceptable to the Company. In
such event, the right of any Holder to include his Registrable Securities in
such registration shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company as
provided in subsection 1.4(e)) enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for such underwriting.
Notwithstanding any other provision of this Section 1.14, if the underwriter
advises the Initiating Holders in writing that marketing factors require a
limitation of the number of shares to be underwritten, then the Initiating
Holders shall so advise all Holders of Registrable Securities which would
otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the underwriting shall be
apportioned (a) first to the holders of the Series C Registrable Securities
selling Series C Registrable Securities pro rata according to the total amount
of Series C Registrable Securities entitled to be included therein owned by each
such selling holder; (b) second to the holders selling Series A and B
Registrable Securities pro rata according to the total amount of Series A and B
Registrable Securities entitled to be included therein owned by each such
selling holder and (c) third, to the extent determined by the underwriters to be
compatible with the offering, to other stockholders.

                                       10
<PAGE>   11
         (c) The Company shall not be obligated to effect, or to take any action
to effect, any registration pursuant to this Section 1.14(a) after the Company
has effected two registrations pursuant to this Section 1.14(a) and such
registrations have been declared or ordered effective; provided, however, that a
registration will not count as a registration pursuant to this Section 1.14(a)
unless the Holders requesting registration are able to register the offering and
sale of at least 50% of the shares of Registrable Securities that they have
requested be included in such registration.

         RIGHTS OFFERING.

         2.1 RIGHTS.

         (a) As used herein, the term "Subsidiary" shall mean, with respect to
the Company, any direct or indirect subsidiary of the Company more than 50% of
the outstanding voting securities of which are owned directly or indirectly by
the Company. The Company shall, upon receipt of a Rights Offering Notice (as
defined below), cause the Subsidiary designated as the "Relevant Subsidiary" in
connection therewith (the "Relevant Subsidiary"), to grant to the holders of the
common stock of Safeguard rights (the "Rights") to purchase from such Relevant
Subsidiary such number of shares of such Relevant Subsidiary's common stock as
determined by Safeguard up to a maximum of 40% of the sum of (i) all issued
shares of common stock of such Relevant Subsidiary, and (ii) all shares of
common stock of such Relevant Subsidiary subject to issuance pursuant to
options, warrants or other agreements, plans, instruments or understandings, all
as of the effective date of the registration statement relating to such Rights
(the "Rights Registration Statement"). The Rights shall be issued in an offering
(the "Rights Offering") pursuant to the Rights Registration Statement, shall be
exercisable for a period of no greater than 45 days after the commencement of
the Rights Offering and shall be transferable by the holder thereof during that
period. The Company shall cause the Relevant Subsidiary to engage an investment
banking firm selected by the Company, subject to the reasonable approval of
Safeguard, which firm shall underwrite, on a standby, firm commitment basis, any
portion of the offered common stock of the Relevant Subsidiary not purchased
through the exercise of Rights. The Company shall also engage legal counsel
selected by Safeguard, subject to the reasonable approval of a majority of the
Board of Directors of the Company, which counsel shall represent the Relevant
Subsidiary in connection with the conduct of the Rights Offering. The exercise
price of the Rights shall be determined by negotiation among the Relevant
Subsidiary, the underwriters and the selling stockholders, if any. Prior to the
commencement of the Rights Offering, the Company shall use its best efforts to
cause (and shall cause the Relevant Subsidiary to use its best efforts to cause)
any holder of more than 1% of the Relevant Subsidiary's common stock (or rights
to acquire more than 1% of the Relevant Subsidiary's common stock) and the
Relevant Subsidiary's officers and directors to execute and deliver to the
underwriter of the Rights Offering a market stand-off agreement. Such market
stand-off agreement shall provide that, during the period of duration specified
by the Relevant Subsidiary and the underwriter of common stock or other
securities of the Relevant Subsidiary following the effective date of the Rights
Registration Statement, such persons shall not, to the extent requested by the
Relevant Subsidiary and such underwriter, directly or indirectly sell, offer to
sell, contract to sell (including, without limitation, any short sale), grant
any option to purchase or otherwise transfer or dispose of (other than to donees
who agree to be similarly bound) any securities of the Relevant Subsidiary held
by them at

                                       11
<PAGE>   12

any time during such period except common stock included in such Rights
Registration Statement.

         (b) Safeguard may initiate a Rights Offering with respect to any
Subsidiary by giving written notice to the Company (a "Rights Offering Notice")
at any time during the Rights Exclusivity Period (as hereinafter defined) at
such time as the total market value of such Subsidiary is at least $35,000,000,
which determination shall be made in good faith, upon request by Safeguard from
time to time, by the Board with the assistance and advice of such experts or
consultants as the Board may choose to retain, if any. The obligations of the
Company pursuant to this Section 2.1 shall commence on the date hereof and
expire on August 6, 2004 (such period, the "Rights Exclusivity Period"), unless
a registration statement relating to a Rights Offering has been filed with the
SEC by such date, in which case the Rights covered by such Registration
Statement shall not expire until 150 days after the date such filing was made.

         (c) The Company agrees that it will not (i) sell or otherwise transfer
any of the capital stock of any Subsidiary owned by it, (ii) permit any
Subsidiary to merge or consolidate with any other person or entity other than
the Company or another Subsidiary or sell, lease or otherwise transfer any
substantial portion of any Subsidiary's assets, or (iii) permit any Subsidiary
to undertake any registration of any of its securities under the Act or the 1934
Act other than pursuant to this Section 2.1, in any case, prior to the earlier
of the expiration of the Rights Exclusivity Period or the completion of a Rights
Offering with respect to such Subsidiary, except with the consent of Safeguard;
provided, however, that this subsection shall not apply to the registration
rights provided under that certain Investors' Rights Agreement, dated as of
September 12, 2000, by and among eMake Corporation and the other parties
thereto.

         (d) Upon closing of a Rights Offering with respect to any Subsidiary,
Safeguard's right to require such Subsidiary to conduct any further Rights
Offerings under this Section 2 and any Directed Shares Offering under Section 3
below shall terminate.

         2.2 SPLIT. After Safeguard has notified the Company of its intention to
commence a Rights Offering, the Company shall, prior to the filing of the Rights
Registration Statement with respect thereto as provided hereinafter (or at such
earlier date as agreed to by the Company and Safeguard), take all such actions
as shall be necessary to cause the Relevant Subsidiary to cause a split of its
authorized common stock in such ratio as Safeguard shall determine. All
references to share amounts in this Agreement other than as specifically noted
shall be deemed to refer to share amounts prior to such split.

         2.3 REGISTRATION STATEMENT. Upon notice by Safeguard to the Company of
its intention to commence a Rights Offering, the Company shall cause the
Relevant Subsidiary to promptly prepare a Rights Registration Statement to
register under the Act, the Rights and the shares of the common stock of the
Relevant Subsidiary to be acquired upon exercise of the Rights (the "Rights
Shares"). The Company covenants that such Rights Registration Statement and the
prospectus included therein shall be in form reasonably satisfactory to
Safeguard, shall comply in all material respects with the Act and the rules and
regulations of the SEC promulgated thereunder, shall not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the

                                       12
<PAGE>   13

circumstances under which they were made, not misleading and shall conform with
the provisions of Section 1.4 hereof.

         2.4 REGISTRATION PROCESS. The Company shall use its best efforts to
cause the Relevant Subsidiary to cause the Rights Registration Statement to be
filed with the SEC and to become effective as promptly as practicable in
accordance with Section 1.4 hereof. The Company shall cause the Relevant
Subsidiary to prepare and file with the SEC, promptly upon Safeguard's request,
any amendments or supplements to the Rights Registration Statement or the
related prospectus that, in Safeguard's opinion, may be necessary or advisable
in connection with the Rights Offering, subject to the reasonable approval of
the Relevant Subsidiary and its counsel. The Company shall not permit the
Relevant Subsidiary to file any amendment or supplement to the Rights
Registration Statement or the related prospectus unless (A) it has furnished
Safeguard with a copy of such amendment or supplement a reasonable time prior to
filing and (B) Safeguard has not reasonably objected to such amendment or
supplement by notice to the Company within 10 days of receipt of such copy. The
Company shall not issue (and shall not permit the Relevant Subsidiary to issue)
any advertisement, press release, mailing or other solicitation material of
which Safeguard reasonably disapproves by prompt written notice to the Company
after receiving reasonable notice thereof. The Company shall cause the Relevant
Subsidiary to comply with the Act and the rules and regulations thereunder in
connection with the Rights Offering and, until the termination of the Rights
Offering, the Company shall cause the Relevant Subsidiary to use its best
efforts to qualify the Rights Shares under the securities laws of all
jurisdictions in which qualification is required and there are holders of
Safeguard common stock and to continue such qualifications in effect during the
exercise period of the Rights. At the time of mailing the prospectus relating to
the Rights Offering and at the time of the closing of the Rights Offering,
Safeguard shall be entitled to receive (A) from the Company and the Relevant
Subsidiary such certificates and documents evidencing compliance with such
representations and warranties of the Company and the Relevant Subsidiary as
Safeguard shall reasonably request of the Company, and (B) from the counsel and
independent accountants of the Company and the Relevant Subsidiary such opinions
and documents as Safeguard may reasonably request thereof as if it were
applicable to the Rights Offering.

         2.5 USE OF PROCEEDS. The Company shall cause the Relevant Subsidiary to
apply all proceeds of the Rights Offering first to the payment of the expenses
of the Rights Offering and thereafter to general working capital purposes or
such other purposes as shall be described in the related prospectus and agreed
to by Safeguard.

         2.6 REGISTRATION SERVICES.

         (a) Services. Safeguard shall diligently and in a timely fashion assist
the Company and the Relevant Subsidiary in structuring the Rights Offering, in
preparing the necessary registration statement and related disclosure
documentation, in clearing the Rights Offering with the SEC and applicable state
securities authorities and shall provide such other services and assistance in
connection with the Rights Offering as the Company or the Relevant Subsidiary
shall reasonably request. Nothing contained herein shall require Safeguard to
provide to the Company or the Relevant Subsidiary any services or assistance
which, if rendered by Safeguard, would require Safeguard to register as a
broker-dealer under Section 15 of the

                                       13
<PAGE>   14

Exchange Act or any state securities laws, or as an investment adviser under the
Investment Advisor Act of 1940, as amended.

         (b) Working Group. The Company shall cause the counsel, auditors,
employees, officers and consultants of the Company and the Relevant Subsidiary
to render such assistance in consummating the Rights Offering, at the expense of
the Company, as is customary in the consummation by a company of its initial
public offering. In addition, in rendering services under this Section 2.6,
Safeguard may engage special legal counsel, one or more rights, registrar and
transfer agents, and such other consultants as Safeguard may deem necessary or
desirable in connection with the Rights Offering, subject to the reasonable
approval of the Company, the expenses of which shall be paid by the Company and
which are not included in the reimbursement described in subsection 2.6(c)
below. In addition, Safeguard may require the Relevant Subsidiary to engage a
registered broker-dealer of Safeguard's designation, subject to the reasonable
approval of the Company, to provide such services in connection with the Rights
Offering as Safeguard may deem reasonably necessary or desirable, including
without limitation, to effect or underwrite the offering of the Rights or the
Rights Shares in states in which applicable state laws require that a registered
broker-dealer effect such offering.

         (c) Expenses. The Company shall bear all reasonable costs and expenses
of the Rights Offering, including, but not limited to, the Relevant Subsidiary's
printing, legal and accounting fees and expenses, SEC and NASD filing fees and
"Blue Sky" fees and expenses; provided, however, that the Company shall have no
obligation to pay or otherwise bear any portion of the underwriters' discounts
attributable to the Rights Shares not being offered and sold by the Relevant
Subsidiary, or the fees and expenses of counsel for the selling holders of
Rights Shares in connection with the registration of the Rights Shares if other
than counsel to the Relevant Subsidiary. The Company shall reimburse Safeguard
for its internal expenses incurred under this Section 2 by payment of $50,000 on
a nonaccountable basis, such payment to be made on the earlier of the closing of
the Rights Offering or 90 days after the Registration Statement is filed.

         2.7 INDEMNIFICATION. In connection with the Rights Offering:

         (a) to the extent permitted by law, the Company will indemnify and hold
harmless Safeguard, any underwriter (as defined in the Act) for Safeguard and
each person, if any, who controls Safeguard or underwriter within the meaning of
the Act or the 1934 Act, against any losses, claims, damages, or liabilities
(joint or several) to which they may become subject under the Act, the 1934 Act
or other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) 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 (iii) any violation or alleged violation by the
Company or the Relevant Subsidiary of the Act, the 1934 Act, any state
securities law or any rule or regulation promulgated under the Act, the 1934 Act
or any state securities law; and the Company will pay to Safeguard and each
underwriter or controlling

                                       14
<PAGE>   15

person, promptly following delivery of an invoice for such amounts incurred, any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
2.7(a) shall not apply to: (x) amounts paid in settlement of any such loss,
claim, damage, liability, or action if such settlement is effected without the
consent of the Company (which consent shall not be unreasonably withheld); (y)
any such loss, claim, damage, liability, or action to the extent that it arises
out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by Safeguard or the underwriter or controlling person;
(z) any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon Safeguard's or the underwriter's failure to
deliver a copy of the registration statement or prospectus or any amendments or
supplements thereto;

         (b) to the extent permitted by law, Safeguard will indemnify and hold
harmless the Relevant Subsidiary, each of its directors, each of its officers
who has signed the registration statement, each person, if any, who controls the
Relevant Subsidiary within the meaning of the Act, any underwriter, any other
Holder selling securities in such registration statement and any controlling
person of any such underwriter or other Holder, against any losses, claims,
damages, or liabilities (joint or several) to which any of the foregoing persons
may become subject, under the Act, the 1934 Act or other federal or state law,
insofar as such losses, claims, damages, or liabilities (or actions in respect
thereto) arise out of or are based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished by Safeguard expressly for use
in connection with such registration; and Safeguard will pay, as incurred, any
legal or other expenses reasonably incurred by any person intended to be
indemnified pursuant to this subsection 2.7(b), in connection with investigating
or defending any such loss, claim, damage, liability, or action; provided,
however, that the indemnity agreement contained in this subsection 2.7(b) shall
not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of
Safeguard, which consent shall not be unreasonably withheld; provided, that, in
no event shall any indemnity under this subsection 2.7(b) exceed the gross
public offering price of all such securities offered by Safeguard and sold
pursuant to such registration statement;

         (c) promptly after receipt by an indemnified party under this Section
2.7(c) of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 2.7, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable

                                       15
<PAGE>   16

time of the commencement of any such action, if prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.7, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 2.7;

         (d) if the indemnification provided for in this Section 2.7 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense 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 that resulted in such loss, liability, claim,
damage, or expense 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 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. In no event shall
any contribution by Safeguard under this subsection 2.7(d) exceed the gross
public offering price of all such securities offered by Safeguard and sold
pursuant to such registration statement. In no event shall a person or entity
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) be entitled to contribution from any person or entity who was not
guilty of fraudulent misrepresentation;

         (e) notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control; and

         (f) the obligations of the Company and Safeguard under this Section 2.7
shall survive the completion of the Rights Offering.

         3. SAFEGUARD SUBSCRIPTION OFFERING.

         3.1 DIRECTED SHARES REGISTRATION. Safeguard shall have the right to
require the Company to cause any Subsidiary to file a registration statement on
Form S-1 for the registration of shares of the Subsidiary's common stock
pursuant to this Section 3 at such time as the total market value of such
Subsidiary is at least $35,000,000 (the "Safeguard Subscription Offering"). Such
registration statement shall register common stock (i) sufficient in number to
satisfy the Directed Shares requirement described below and (ii) with an
aggregate offering price, prior to underwriting discounts and commissions, of at
least $10,000,000. In connection with such Safeguard Subscription Offering, the
Company shall cause the applicable Subsidiary to adjust its authorized shares as
requested by Safeguard in order to facilitate distribution of Directed Shares to
its stockholders. The Company shall cause the applicable Subsidiary to engage
(i) an underwriter or underwriters selected by Safeguard, subject to the

                                       16
<PAGE>   17

approval of a majority of the Board of Directors of the Company, and (ii) legal
counsel selected by Safeguard, subject to the reasonable approval of a majority
of the Board of Directors of the Company, which counsel shall represent the
applicable Subsidiary in connection with the conduct of the Safeguard
Subscription Offering.

         3.2 DIRECTED SHARES SUBSCRIPTION PROGRAM. In connection with the
Safeguard Subscription Offering, the Company shall cause the applicable
Subsidiary to:

         (a) provide in the related underwriting agreement a right for Safeguard
to designate persons (the "Safeguard Designees") who may purchase from the
underwriter(s) shares of the Relevant Subsidiary's common stock (the "Directed
Shares") at the public offering price of such Subsidiary's common stock in the
Safeguard Subscription Offering (the "IPO Price"); and

         (b) use its best efforts to cause such Subsidiary to cause the
underwriters of the Safeguard Subscription Offering to allow the Safeguard
Designees to purchase at the IPO Price that number of Directed Shares equal to
20% of the shares of common stock offered by such Subsidiary in such Safeguard
Subscription Offering. Upon closing of the Safeguard Subscription Offering with
respect to any Subsidiary and sale of the number of shares set forth in this
Section 3.2(b), Safeguard's right to require the Company to cause such
Subsidiary to conduct a Rights Offering pursuant to Section 2 above shall
terminate. The Company shall reimburse Safeguard for its internal expenses
incurred under this Section 3 by payment of $50,000 on a nonaccountable basis,
such payment to be made on the earlier of the closing of the Safeguard
Subscription Offering or 90 days after the Registration Statement is filed.

         4. BOARD NOMINATIONS. In addition to its right to designate one of
the members of the Board of Directors of the Company pursuant to the Company's
Certificate of Designation for Series C-1 Preferred Stock and Series C-2
Preferred Stock, for so long as SCP owns at least 5% of the outstanding Common
Stock of the Company (on an as-converted basis), SCP shall have the right to
propose one director for election to the Board of Directors of the Company and
the Company shall take all steps necessary to nominate such proposed director
for election to the Company's Board of Directors at its annual meeting of
stockholders.

         5. MISCELLANEOUS.

         5.1 SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, the
terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the respective successors and assigns of the parties. Nothing in
this Agreement, express or implied, is intended to confer upon any party other
than the parties hereto or their respective successors and assigns any rights,
remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement.

         5.2 GOVERNING LAW. The construction, validity and interpretation of
