EXHIBIT 4.1

                            STOCKHOLDERS' AGREEMENT


            Stockholders' Agreement (as such agreement may be amended from time
to time, this "Agreement"), dated as of December 21, 2000, by and among HP
Acquisition Corp., a Delaware corporation ("HPAC"), WC Holdings, Inc., a
Delaware corporation ("WC Holdings"), Security Capital Corporation, a Delaware
corporation ("SCC"), and Robert J. Bossart, Randy E. Jones, Richard T. Kurth,
Paul A. Miller, Daniel R. Sullivan and Jonathan R. Wagner (such persons being
referred to individually as a "Management Holder" and collectively as the
"Management Holders").

                                    RECITALS

            A. Security Capital, HPAC and Health Power, Inc., a Delaware
corporation ("Health Power") are parties to an Agreement and Plan of Merger
dated as of June 8, 2000, as amended (the "Merger Agreement") pursuant to which,
as of the Effective Time (as defined in the Merger Agreement), HPAC will be
merged with and into Health Power, with Health Power continuing as the surviving
corporation, and with each share of the Common Stock, par value $.01 per share,
of HPAC ("HPAC Common Stock") which is issued and outstanding as of the
Effective Time being converted into and becoming one fully paid and
nonassessable share of the Common Stock, par value $.01 per share, of Health
Power ("Health Power Common Stock").

            B. In connection with the transactions contemplated by the Merger
Agreement, the Management Holders have agreed to acquire, for a total
consideration of $2,000,000, shares of HPAC Common Stock which, in the
aggregate, will represent twenty percent (20%) of the outstanding shares of HPAC
Common Stock as of immediately prior to the Effective Time, and WC Holdings has
agreed to acquire, for a total consideration of $8,000,000, shares of HPAC
Common Stock which, in the aggregate, will represent eighty percent (80%) of the
outstanding shares of HPAC Common Stock immediately prior to the Effective Time.
Pursuant to the Health Power, Inc. 2000 Management Stock Option Plan (the
"Option Plan"), to be adopted and approved by the Board of Directors and
stockholders of Health Power as soon as practicable following the Effective
Time, and separate option agreements to be entered into between Health Power and
each of the Management Holders and one or more other key employees of Health
Power or its Subsidiaries in accordance therewith, the Company will grant the
Management Holders and such other employee or employees options ("Options") to
purchase, in the aggregate, up to an additional five percent (5%) of the number
of shares of Health Power Common Stock which are issued and outstanding as of
the Effective Time.

            C. In order to prevent the exercise of any Options from causing SCC
to hold at any time, directly or indirectly, less than eighty percent (80%) of
the outstanding Health Power Common Stock, as well as to provide the Management
Holders liquidity with respect to their respective ownership interests in Health
Power following the Effective Time, the parties, among other things, wish to set
forth the circumstances under which (i) the Management Holders may exchange
their shares of Health Power Common Stock, or the vested portions of their
Options, for shares of the Class A Common Stock, par value $.01 per share, of
SCC ("SCC Common Stock"), or cash, if SCC so elects, or (ii) SCC or Health Power
may require that the Management Holders effect such an exchange.

            D. The parties also desire to promote their mutual interests by
imposing certain other restrictions and obligations on themselves, Health Power
and the shares of Health Power Common Stock or other equity securities of Health
Power or SCC now held or hereafter acquired by them.

Notwithstanding any provision of this Agreement (or any other agreement between

"Participation Notice") addressed to the Secretary during the Applicable Notice
Period, specifying the number of Shares and/or the Vested Options (or portions
thereof) (collectively, the "Put Securities") which he

<PAGE>
wishes to exchange for SCC Shares, provided that in no event shall such
Participation Notice be effective to the extent that the Applicable Lot Limit
would be exceeded with respect to any Original Lot of such Participating Holder.

            (b) The purchase price payable to a Participating Holder for his Put
Securities shall be equal to (i) the product of (A) the sum of the number of
Shares, plus the number of Vested Option Shares, covered by the Put Securities,
multiplied by (B) the Fair Market Value Per Share (as defined below), reduced by
(ii) the aggregate exercise price applicable to any Vested Option Shares covered
by the Put Securities.

            (c) SCC may, in its sole and absolute discretion, elect to pay the
purchase price for the Put Securities of any Participating Holder with SCC
Shares, in cash, or in any combination of cash and SCC Shares, and to the extent
payable in cash, SCC may substitute WC Holdings, the Company or any other
Affiliate or Subsidiary of SCC as the purchaser of Put Securities. To the extent
that SCC elects to pay for Put Securities with SCC Shares, the number of SCC
Shares to be issued to the Participating Holder shall be equal to (x) the
purchase price of such Put Securities (as determined in accordance with Section
2.02(b) above), divided by (y) the SCC Fair Market Value Per Share.

            (d) "Fair Market Value Per Share" shall be determined as follows:

                  (i) Such value may be determined by mutual agreement between
SCC and Participating Holders holding a majority in interest of the Put
Securities subject to Final Submission Notices (as defined below).

                  (ii) If such value is not agreed upon in accordance with
clause (i) above, and the Company has had an initial public offering and the
Common Stock is then publicly traded, then such value shall be determined in the
same manner that the SCC Fair Market Value Per Share would be determined for the
Applicable Notice Period.

                  (iii) If neither of clauses (i) or (ii) above is applicable,
and within the twelve (12) month period preceding the beginning of the
Applicable Notice Period, the Company has completed one or more bona fide
private sales of Common Stock (whether to SCC, any Affiliate of SCC or any
unrelated third party), or, as of the beginning of the Applicable Notice Period,
any such sale is pending, then such value shall be deemed equal to the per share
price to be paid in connection with the pending sale or, if none, then such
value shall be deemed equal to the per share price paid in connection with the
most recent of such completed sales.

                  (iv) If none of clauses (i), (ii) or (iii) above is
applicable, SCC only, in its sole and absolute discretion, may elect to have
such value determined by applying the following formula:

                               (W+X-Y)
            FMVPS       =     --------
                                  Z

            Where:

            W     =     The aggregate exercise price with respect to all options
                        which are referred to in the determination of Z below;

            X     =     The product of six (6) multiplied by the Company's
                        operating profits (defined as earnings of the Company
                        and its Subsidiaries on

                                     -6-
<PAGE>
                        a consolidated basis, before interest, taxes,
                        amortization of intangibles, and parent company charges
                        (except for parent company out of pocket cash expenses),
                        and determined on the basis of the Company's financial
                        statements) for the most recently completed fiscal year
                        of the Company;

            Y     =     Indebtedness of the Company and its Subsidiaries
                        outstanding as at the end of the most recently completed
                        fiscal year of the Company (including interest-bearing
                        debt, seller notes or other non-interest- bearing debt,
                        deferred revenue, other debt equivalents, revolving debt
                        and inter-company payables or advances between the
                        Company or any of its Subsidiaries and any parent
                        entity, netted against inter-company receivables
                        (specifically including WC Holdings and SCC)), provided
                        that (a) the revolving debt deemed to be outstanding
                        will be the sum of the month-end outstanding balances of
                        revolving debt divided by twelve, and (b) Indebtedness
                        outstanding at December 31 of any year will be deemed to
                        be reduced by the sum of the month-end cash balances
                        divided by twelve, regardless of whether revolving debt
                        is outstanding at any month end; and

            Z     =     The total number of outstanding shares of Common Stock
                        as at the beginning of the Applicable Notice Period,
                        plus the number of Shares which could be acquired by the
                        exercise of all outstanding Options, warrants or
                        equivalents thereof, whether or not then fully
                        exercisable.

                  (v) If none of clauses (i), (ii) or (iii) above is applicable,
and SCC does not elect to have Fair Market Value Per Share determined by
applying the formula set forth in clause (iv) above, then such value shall be
determined by an Appraiser selected by Participating Holders holding a majority
in interest of the Put Securities subject to Final Submission Notices, as to
which selection SCC shall not unreasonably object.

            (e) On or before May 15 of each calendar year in which one or more
effective Participation Notices has been delivered, the Secretary shall give
written notice (a "Terms Notice") to each Participating Holder (i) acknowledging
the number and types of Put Securities specified in his Participation Notice,
and, if relevant, specifying the extent to which such Participation Notice is
not effective due to the application of Applicable Lot Limits, (ii) specifying
the applicable basis, based on the provisions of Section 2.02(d) above, upon
which SCC believes Fair Market Value Per Share should be determined (and
relevant supporting information if appropriate), and (iii) specifying the type
of consideration to be paid to Participating Holders in exchange for their Put
Securities or, if applicable, the respective percentages of the total purchase
price to be paid in SCC Shares and cash, respectively.

            (f) Within fifteen (15) days after all Participating Holders have
received a Terms Notice, or such later date to which such period may be extended
in writing by the Secretary prior to the end of such fifteen (15) day period
(the "Final Submission Period"), each Participating Holder who still wishes to
participate in the Exchange Opportunity for the current calender year must give
written notice (a "Final Submission Notice") addressed to the Secretary,
confirming the Put Securities which he wishes to exchange and acceptance of the
terms of such exchange, as described in the Terms Notice, or if relevant,
specifying any objections that the Participating Holder has with respect to such
terms. As soon as practicable following the end of

                                     -7-
<PAGE>
the Final Submission Period, SCC and the Participating Holders who submitted
Final Submission Notices ("Confirmed Participants") shall cooperate in good
faith to finalize the determination of the Fair Market Value Per Share and
otherwise complete the exchange of the Put Securities for SCC Shares and/or
cash, as the case may be, in accordance with the provisions of this Agreement,
as soon as reasonably practicable. The obligation of SCC or any Affiliate
thereof, however, to complete any such exchange with a Confirmed Participant
shall be subject to the Confirmed Participant's ability to deliver his Put
Securities free and clear of all Liens.

            Section 2.03. RIGHT OF SCC TO DEFER EXCHANGE. In each calendar year
SCC may elect, by written notice (a "Deferral Notice") given to each Confirmed
Participant, to defer performance of its obligation to purchase the Put
Securities of any Confirmed Participant, for a period of up to sixty (60) days
after the terms of such purchase have been finalized in accordance with the
provisions of Section 2.02 above, or such later date to which such period may be
extended in writing by a majority in interest of the Confirmed Participants
prior to the end of such sixty (60) day period (the "Deferral Period"), to the
extent, but only to the extent, that such performance is, at the time of such
deferral, prohibited or otherwise limited by applicable law, agreements with
lenders, including, without limitation, any of the Senior Loan Agreements or any
of the Subordinated Loan Agreements, or by any other agreements or
circumstances, in each case as determined by the Board of Directors of SCC
acting in good faith and described in the Deferral Notice. Following the
Deferral Notice, SCC will utilize commercially reasonable efforts to obtain any
required waivers or consents from lenders or other third persons so as to permit
it (or its Affiliates) to fully perform its obligation to purchase any Put
Securities in accordance herewith (PROVIDED, HOWEVER, that the foregoing shall
not obligate SCC to seek additional funding), or may submit a proposal for the
purchase of the Put Securities by some alternative means which SCC is able to
fully perform and which is acceptable to a majority in interest of the Confirmed
Participants (an "Alternative Proposal"). If during the Deferral Period, SCC is
unable to fully perform its obligation to purchase the Put Securities in
accordance herewith, and does not provide an Alternative Proposal, then a
majority in interest of the Confirmed Participants may elect, by written notice
given to SCC within the period ending (30) days after the last day of the
Deferral Period, or such later date to which such period may be extended in
writing by SCC prior to the end of such thirty (30) day period (the "Sale
Transaction Notice Period"), to require SCC to engage an investment banking
firm, reasonably acceptable to a majority in interest of the Confirmed
Participants, to seek consummation of a business combination or other corporate
transaction (a "Sale Transaction"), the terms of which would include the sale or
exchange of the Put Securities on the same terms that the Shares held by SCC or
its Affiliate would be sold or exchanged in connection therewith.
Notwithstanding the foregoing, at any time prior to the consummation of any Sale
Transaction, SCC shall retain the right to purchase the Put Securities in
accordance with the terms on which the Put Securities would have previously been
purchased hereunder, but for the deferral of such obligation, instead of
completing the Sale Transaction. If a Sale Transaction Notice is not given to
SCC within the Sale Transaction Notice Period, then, unless otherwise agreed by
a majority in interest of the Confirmed Participants and SCC, all Final
Submission Notices for the then current calendar year shall be deemed withdrawn,
and all further obligations of SCC or any Affiliate in respect of the Put
Securities described therein shall be terminated. However, in subsequent years,
the Exchange Opportunity shall continue to be made available to Holders in
accordance with the provisions of, and subject to the limitations of (including
Applicable Lot Limits), of this Article II above.

            Section 2.04. EXCHANGE OPPORTUNITY AND OTHER PROVISIONS OF THIS
AGREEMENT SUBJECT TO AGREEMENTS WITH LENDERS AND APPLICABLE LAW. Notwithstanding
anything in this Agreement to the contrary, including, without limitation the
provisions of Sections 2.01 through 2.03 above, in no event shall SCC or any
Affiliate, including, without limitation, WC Holdings,

                                     -8-
<PAGE>
the Company or any of their respective Subsidiaries, be required to take any
action which is, or would be, in contravention of, or would constitute an event
of default or an event which, upon notice, the passage of time, or both, would
constitute an event of default (as the foregoing terms are so defined), under
agreements with their respective lenders, including, without limitation, any of
the Senior Loan Agreements or any of the Subordinated Loan Agreements, or in
violation of applicable law, and each of the Holders acknowledges, agrees and
confirms that (i) as at the Effective Time and for an indeterminable amount of
time thereafter, his respective right to exercise the Exchange Opportunity will
be subject to certain limitations and restrictions imposed pursuant to the terms
of certain agreements with lenders, including, without limitation, the Senior
Loan Agreements and the Subordinated Loan Agreements, and that (ii)
notwithstanding the provisions of Section 2.03, to the extent, from time to
time, that any proposed exercise of the Exchange Opportunity by any Holder (or
by more than one Holder in the aggregate) would cause any such limitations or
restrictions to be violated, the only obligation of SCC or any Affiliate to such
Holder or Holders in such event shall be to request in writing to the applicable
lender(s) that the application of such requirements be waived or otherwise
modified to permit such exercise. In addition, to the extent that any other
provision of this Agreement, including, without limitation, any of the
provisions of Article IV or Article V hereof, are (whether as written or as
might be applied in a particular instance (such as, by way of example only, the
requirement for Company and SCC Acceptance of an Instrument of Accession under
Sections 4.01 or 5.02)) in conflict with, or the application of which would
interfere with, the exercise of the rights of the Senior Lender or the
Subordinated Lender, as the case may be, under the Senior Loan Agreements or the
Subordinated Loan Agreements (including, without limitation, the Stock Pledge
Agreement (as defined in the Subordinated Loan Documents), respectively, the
rights of the Senior Lender or the Subordinated Lender, as the case may be,
shall prevail.

                                   ARTICLE III
                                TAKE-ALONG RIGHTS

            Section 3.01. TAKE-ALONG PROVISIONS. If at any time Stockholders
(including, for purposes of clarification, any Person who becomes an owner of
Shares in connection with the exercise by the Subordinated Lender of its rights
under the Stock Pledge Agreement) owning at least a majority of the Shares (the
"Majority Take-Along Holders") shall approve a Significant Issuer Transaction,
such Majority Take-Along Holders shall have the right and option to require the
Company and each other Stockholder to consent to, vote for, or otherwise not
dissent to the approval of such Significant Issuer Transaction in any
stockholders' action to be taken with respect thereto, and to take any and all
action and to do and perform any and all acts and things deemed reasonably
necessary by the Majority Take-Along Holders to effect the Significant Issuer
Transaction, on the same terms and conditions applicable to the Majority
Take-Along Holders. In addition, if at any time Majority Take-Along Holders
shall propose that the Stockholders sell to a purchaser or related group of
purchasers, in a single transaction or related series of transactions, such
number of Shares as equals or exceeds fifty percent (50%) or more of the
outstanding Shares (a "Stock Offer"), then the Majority Take-Along Holders shall
have the right and option to require each other Stockholder to sell up to his
Take-Along Pro Rata Portion of his respective Shares to the prospective third
party purchaser, and to take any and all action and to do and perform any and
all acts and things deemed reasonably necessary by the Majority Take-Along
Holders to effect such sales, on the same terms and conditions applicable to the
Majority Take-Along Holders.

            Section 3.02. SUSPENSION/TERMINATION OF EXCHANGE OPPORTUNITY
PROVISIONS. The Exchange Opportunity (and all rights and obligations in respect
thereof) shall be suspended during the pendency of a Stock Offer or a
Significant Issuer Transaction to the extent, but only to the extent, that the
consummation thereof would result in the purchase of a Holder's Shares or

                                     -9-
<PAGE>
Vested Options, and shall terminate upon the consummation of any such
transaction with respect to the Shares and Vested Options of a Holder which are
so purchased.

                                   ARTICLE IV
                  RESTRICTIONS ON TRANSFER; REGISTRATION RIGHTS

      Section 4.01. RESTRICTIONS ON TRANSFER.

            (a) Except as expressly permitted or required by this Agreement, no
Shares or Options shall be sold, assigned, transferred, or pledged by any
Management Holder, to any Person other than a Permitted Transferee of such
Holder, without the prior written consent of the Board of Directors of the
Company. No transferee of any Holder (including any Permitted Transferee) shall
be entitled to the benefits of this Agreement unless and until such transferee
has executed and delivered to the Company and SCC an Instrument of Accession
and, in the case of a transferee other than a Permitted Transferee, such
Instrument of Accession has been accepted by the Company and SCC.

            (b) No Restricted Securities shall be sold, assigned, transferred,
or pledged by any Holder, except upon the conditions specified in this Article
IV, which conditions are intended to ensure compliance with the provisions of
the Securities Act. Each Holder shall cause any proposed transferee of
Restricted Securities held by a Holder to agree in writing to take and hold such
securities subject to the provisions and upon the conditions specified in this
Article IV.

            Section 4.02. RESTRICTIVE LEGENDS.

            (a) Each certificate representing Shares or Restricted Securities
shall (unless otherwise permitted by the provisions of Section 4.03 below) be
stamped or otherwise imprinted with legends in substantially the following form
to the extent applicable (in addition to any legend(s) required under applicable
state securities laws):

      THE SALE AND ISSUANCE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE
      HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
      "ACT"), OR UNDER THE SECURITIES LAW OF ANY STATE OR OTHER JURISDICTION.
      THESE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO,
      OR IN CONNECTION WITH, THE DISTRIBUTION THEREOF. THESE SECURITIES MAY NOT
      BE OFFERED, SOLD, PLEDGED, OR TRANSFERRED UNLESS (I) A REGISTRATION
      STATEMENT UNDER THE ACT IS IN EFFECT AS TO THESE SECURITIES AND SUCH
      OFFER, SALE, PLEDGE, OR TRANSFER IS IN COMPLIANCE WITH THE APPLICABLE
      SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION OR (II) THERE IS AN
      OPINION OF COUNSEL OR OTHER EVIDENCE, IN EITHER CASE, SATISFACTORY TO THE
      CORPORATION, THAT AN EXEMPTION THEREFROM IS AVAILABLE AND THAT SUCH OFFER,
      SALE, PLEDGE, OR TRANSFER IS IN COMPLIANCE WITH THE APPLICABLE SECURITIES
      LAWS OF ANY STATE OR OTHER JURISDICTION.

      FURTHERMORE, THE SALE, PLEDGE, HYPOTHECATION, TRANSFER OR OTHER
      DISPOSITION OF THESE SECURITIES ARE RESTRICTED PURSUANT TO THE TERMS OF A
      STOCKHOLDERS' AGREEMENT DATED DECEMBER 21, 2000, AMONG THE CORPORATION,
      THE HOLDER OF THIS CERTIFICATE AND CERTAIN OTHER PERSONS. COPIES OF SUCH
      AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER
      OF

                                     -10-
<PAGE>
      RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION AT THE
      PRINCIPAL EXECUTIVE OFFICES OF THE CORPORATION.

            (b) Each Holder and any subsequent holder of any Shares or
Restricted Securities consents to the Company or SCC, as the case may be, making
a notation on its records and giving instructions to any transfer agent of any
Shares or Restricted Securities in order to implement the restrictions on
transfer described in this Article IV. SCC shall be obligated to reissue
promptly certificates without the first of the foregoing legends at the request
of any Holder of Restricted Securities if the Holder shall have obtained an
opinion of counsel (which counsel may be counsel to SCC) reasonably acceptable
to SCC to the effect that the securities proposed to be disposed of may lawfully
be so disposed of without registration, qualification or legend. Any legend
endorsed on an instrument pursuant to applicable state securities laws and the
stop-transfer instructions with respect to such securities shall be removed upon
receipt by SCC of an order of the appropriate blue sky authority authorizing
such removal or an opinion of counsel reasonably satisfactory to SCC to the
effect that any such applicable state securities legends or stop-transfer
instructions are not required and may be removed.

            (c) Each Holder (other than the Subordinated Lender upon exercise of
its rights under the Subordinated Loan Agreements, including, without
limitation, the Stock Pledge Agreement), by signing this Agreement or causing it
to be signed, represents and warrants to the Company and SCC that such Holder is
acquiring or has acquired his Shares for his own account for investment and not
with a view to, or for resale in connection with, the distribution thereof.

      Section 4.03. NOTICE OF PROPOSED TRANSFERS. Prior to any proposed transfer
of any Restricted Securities, unless there is in effect a registration statement
under the Securities Act covering the proposed transfer, the holder thereof
shall give written notice to SCC of such Holder's intention to make such
transfer. Such notice shall describe the manner and circumstances of the
proposed transfer in sufficient detail, and shall be accompanied by a written
opinion of legal counsel who shall be reasonably satisfactory to SCC, addressed
to SCC and reasonably satisfactory in form and substance to SCC's counsel, to
the effect that the proposed transfer of the Restricted Securities may be
effected without registration under the Securities Act; PROVIDED, HOWEVER, that
for transactions made pursuant to Rule 144 under the Securities Act, an opinion
of counsel shall only be required if reasonably requested by SCC and which shall
be to the effect that the proposed transfer of the Restricted Securities may be
effected without registration under the Securities Act. Each certificate
evidencing the Restricted Securities so transferred shall bear the restrictive
legend set forth in Section 4.02, except that such certificate shall not bear
such restrictive legend if in the opinion of counsel for SCC such legend is not
required in order to establish compliance with any provisions of the securities
laws.

      Section 4.04. PIGGYBACK REGISTRATION.

            (a) If at any time or from time to time, SCC shall determine to
register in an underwritten offering any of its securities, either for its own
account or the account of a security holder or holders, other than (i) a
registration relating solely to employee benefit plans, or (ii) a registration
relating solely to Rule 145 transaction, or a registration on any registration
form that does not permit secondary sales, SCC shall:

                  (i) promptly give to each Holder written notice thereof; and

                  (ii) include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable

                                     -11-
<PAGE>
Securities specified in a written request by each Holder, in each case received
by SCC within twenty (20) days after SCC mails such written notice, subject to
the provisions below.

            (b) The right of any Holder to registration pursuant to this Section
4.05 shall be conditioned upon the participation by such Holder in such
underwriting and the inclusion of Registrable Securities of such Holder in the
underwriting to the extent provided herein. Those parties proposing to
distribute their securities through such underwriting shall (together with SCC
and the other holders distributing their securities through such underwriting)
enter into an underwriting agreement in customary form with the managing
underwriter selected for such underwriting by SCC. Notwithstanding any other
provisions of this Section 4.04, if the managing underwriter determines that
marketing factors require a limitation on the number of shares to be
underwritten or a limitation on the number of Registrable Securities or other
securities to be underwritten, the managing underwriter may limit the
Registrable Securities or other securities to be included in such registration.
SCC shall so advise all Holders and any other holders distributing their
securities through such underwriting, and the number of shares of Registrable
Securities and other securities that may be included in the registration and
underwriting shall be allocated among SCC, the Holders and any other holders as
follows: First, to SCC so as to permit SCC to include all shares that SCC
desires to sell; and second, to all Holders and other holders pro rata, in
proportion to the respective amounts of Registrable Securities or other
securities entitled to inclusion in such registration held by such Holders and
other holders at the time of the filing of the registration statement. If any
Holder or other holder disapproves of the terms of any such underwriting, he may
elect to withdraw therefrom by written notice to SCC and the managing
underwriter. Any securities excluded or withdrawn from such underwriting shall
be withdrawn from such registration, and shall not be transferred in a public
distribution prior to one hundred eighty (180) days after the effective date of
the registration statement relating thereto, or such other shorter period of
time as the underwriters may require.

            (c) SCC shall have the right to terminate or withdraw any
registration initiated by it under this Section 4.04 prior to the effectiveness
of such registration whether or not any Holder has elected to include securities
in such registration.

      Section 4.05. FORM S-3 REGISTRATION. SCC shall use its reasonable best
efforts to remain qualified for registration on Form S-3. As long as SCC remains
qualified for the use of Form S- 3, in addition to the rights contained in
Section 4.04, one or more Holders or holders of other securities which may be
entitled to inclusion in a registration by SCC on Form S-3 shall have the right
to request registration on Form S-3 (all such requests shall be in writing and
shall state the number of shares of Registrable Securities or other securities
to be disposed of and the intended methods of disposition of such shares by such
Holders or other holders); PROVIDED, HOWEVER, that no request will be honored
with respect to any proposed S-3 offering which would not include at least
1,000,000 SCC Shares. In case SCC shall receive from Holders a written request
that SCC effect a registration on Form S-3 and any related state securities
qualification or blue sky compliance with respect to such an amount of the
Registrable Securities owned by such Holders, SCC shall:

            (a) promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders; and

            (b) as soon as practicable, use its reasonable best efforts to
effect such registration and all such qualifications and compliances as may be
so requested and as would permit or facilitate the sale and distribution of all
or such portion of such Holders' Registrable Securities as are specified in such
request, together with all or such portion of the Registrable

                                     -12-
<PAGE>
Securities of any other Holders joining in such request as are specified in a
written request given within twenty (20) days after receipt of such written
notice from SCC; PROVIDED, HOWEVER, that SCC shall not be obligated to effect
any such registration, qualification, or compliance pursuant to this Section
4.05: (i) if Form S-3 is not available for such offering by Holders; (ii) if SCC
has, within the twelve (12) month period preceding the date of such request,
already effected one registration on Form S-3 pursuant to this Section 4.05; or
(iii) in any jurisdiction in which SCC would be required to execute a general
consent to service of process in effecting such registration, qualification, or
compliance unless SCC is already subject to service in such jurisdiction and
except as may be required by the Securities Act.

      Subject to the foregoing, SCC shall effect such registration,
qualification, or compliance (including, without limitation, the execution of an
undertaking to file post-effective amendments, appropriate qualification under
applicable blue sky or other state securities laws and appropriate compliance
with applicable regulations issued under the Securities Act and any other
governmental requirements or regulations) covering the Registrable Securities so
requested to be registered as soon as practicable after receipt of the request
or requests of the Holders.

      If any registration to be effected pursuant to this Section 4.05 is to be
an underwritten public offering, it shall be managed by an underwriter or
underwriters acceptable to SCC and selected by a majority in interest of the
Holders and other holders requesting registration. In such event, the right of
any Holder to registration pursuant to this Section 4.05 shall be conditioned
upon the participation by such Holder in such underwriting and the inclusion of
the Registrable Securities of such Holder in the underwriting to the extent
provided herein. If the managing underwriter so selected determines that
marketing factors require a limitation of the number of shares to be
underwritten, the managing underwriter may limit the Registrable Securities held
by such Holders and other holders to be included in such registration. SCC shall
so advise such Holders and other holders, and the number of shares of
Registrable Securities that may be included in the registration shall be
allocated among the Holders of Registrable Securities and other holders pro
rata, in proportion to the respective amounts of Registrable Securities and
other securities entitled to inclusion in such registration held by such Holders
and other holders at the time of the filing of the registration statement. Any
Registrable Securities that are so excluded from the underwriting shall be
excluded from the registration. As used throughout this Section the term "Form
S-3" shall be deemed to include any equivalent successor form for registration
pursuant to the Act.

      Section 4.06. REGISTRATION PROCEDURES. In connection with any registration
of Registrable Securities required under this Article IV, SCC shall:

            (a) Prepare and file with the Commission a registration statement
with respect to such Registrable Securities and use its reasonable best efforts
to cause such registration statement to become and remain effective as provided
herein.

            (b) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
current and to comply with the provisions of the Securities Act with respect to
the sale of or other disposition of all Registrable Securities covered by such
registration statement, including such amendments and supplements as may be
necessary to reflect the intended method of disposition of the prospective
seller or sellers of such Registrable Securities, but for no longer than one
hundred eighty (180) days subsequent to the effective date of such registration
in the case of a registration statement on Form S-1 (or any similar form of
registration statement required to set forth substantially identical
information); PROVIDED, HOWEVER, that (i) such period shall be extended for a
period of

                                     -13-
<PAGE>
time equal to the period the underwriter recommends that the Holders refrain
from selling the securities included in such registration due to marketing
conditions or other conditions which adversely affect the offer and sale of such
securities; and (ii) in the case of any registration of Registrable Securities
on Form S-3 which is intended to be offered on a continuous or delayed basis,
such period shall be extended, if necessary, to keep the registration statement
effective until all such Registrable Securities are sold, provided that Rule 415
permits an offering on a continuous or delayed basis, and provided further that
applicable rules under the Securities Act governing the obligation to file a
post-effective amendment permit, in lieu of filing a post- effective amendment
that (I) includes any prospectus required by Section 10(a)(3) of the Securities
Act or (II) reflects facts or events representing a material or fundamental
change in the information set forth in the registration statement, the
incorporation by reference of information required to be included in (I) and
(II) above to be contained in periodic reports filed pursuant to Section 13 or
15(d) of the Exchange Act in the registration statement.

            (c) Furnish to each prospective seller of Registrable Securities
such number of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other
documents, as such seller may reasonably request in order to facilitate the
public sale or other disposition of the Registrable Securities of such seller.

            (d) Notify each seller of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities 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 or incomplete in the light of the
circumstances then existing, and at the request of any such seller, prepare and
furnish to such seller a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers 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 not misleading or
incomplete in the light of the circumstances then existing.

            (e) Cause all such Registrable Securities registered hereunder to be
listed on each securities exchange or approved for quotation on any inter-dealer
quotation system on which similar securities issued by SCC are then listed or
quoted.

            (f) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to such registration statement and a CUSIP number
of all such Registrable Securities not later than the effective date of such
registration.

            (g) Otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the Commission.

      Each Seller of Registrable Securities shall not (until further notice)
effect sales of shares covered by any registration statement after receipt of
telegraphic or written notice from SCC to suspend sales to permit SCC to correct
or update a registration statement or prospectus.

      Section 4.07. EXPENSES OF REGISTRATION. All Registration Expenses shall be
borne by SCC; PROVIDED, HOWEVER, that in connection with any registration of
securities, SCC shall only be responsible for the fees and costs of one counsel
for the Holders (selected by a majority in interest of the Holders of
Registrable Securities participating in the offering). All Selling Expenses
relating to securities so registered shall be borne by the holders of such
securities pro rata on the basis of the number of shares of securities so
registered on their behalf.

                                     -14-
<PAGE>
      Section 4.08. INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under this Article IV:

            (a) SCC will indemnify each Holder, each underwriter, if any, and
each Person who controls any underwriter within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages or liabilities (or
actions in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened, arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained, on the effective date thereof, in any registration statement, any
prospectus contained therein, or any amendment or supplement thereto, or based
on any omission (or alleged omission) to state therein a material fact required
to be stated therein or necessary to make the statements therein (in the case of
a prospectus, in the light of the circumstances under which they were made) not
misleading, or any violation by SCC of any rule or regulation promulgated under
the Securities Act applicable to SCC in connection with any such registration,
qualification or compliance, and SCC will reimburse each such Holder, each such
underwriter and each person who controls any such underwriter, for any legal and
any other expenses reasonably incurred in connection with investigating,
preparing or defending any such claim, loss, damage, liability or action,
provided that SCC will not be liable in any such case to the extent that any
such claim, loss, damage, liability or expense arises out of or is based on any
untrue statement or omission or alleged untrue statement or omission, made in
reliance upon and in conformity with written information furnished to SCC by
such Holder or underwriter and stated to be specifically for use therein. If the
Holders are represented by counsel other than counsel for SCC, SCC shall not be
obligated under this Section 4.08 to reimburse legal fees and expenses of more
than one separate counsel for the Holders.

            (b) Each Holder, severally and not jointly, will, if Registrable
Securities held by such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify SCC, each
of its directors and officers and its legal counsel and independent accountants,
each underwriter, if any, of SCC's securities covered by such a registration
statement, and each person who controls SCC or such underwriter within the
meaning of Section 15 of the Securities Act, against all claims, losses, damages
and liabilities (or actions in respect thereof), including any of the foregoing
incurred in settlement of any litigation commenced or threatened, arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained, on the effective date thereof, in any such registration
statement, any prospectus contained therein, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of a prospectus, in the
light of the circumstances under which they were made) not misleading, and will
reimburse SCC, and such directors, officers, persons, underwriters or control
persons for any legal or any other expenses reasonably incurred in connection
with investigating or defending any such claim, loss, damage, liability or
action, in each case to the extent, but only to the extent, that such untrue
statement (or alleged untrue statement) or omission (or alleged omission) is
made in such registration statement or prospectus in reliance upon and in
conformity with written information furnished to SCC by such Holder and stated
to be specifically for use therein; PROVIDED, HOWEVER, that the obligations of
each Holder shall be limited to an amount equal to the net proceeds to each such
Holder of Registrable Securities sold as contemplated herein.

            (c) Each party entitled to indemnification under this Section 4.08
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the

                                    -15-
<PAGE>
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 4.08 to the extent such
failure is not prejudicial. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation. Notwithstanding anything to the contrary contained in this
Section 4.08(c), the Indemnified Party shall have the right to employ its own
counsel in any action, claim, litigation, proceeding or investigation, and the
fees and expenses thereof shall be borne by the Indemnified Party, unless the
Indemnified Party shall have reasonably concluded that there may be one or more
legal defenses available to it which are different from or additional to those
available to the Indemnifying Party, in which case the Indemnifying Party shall
bear all of such Indemnified Party's legal and other fees and expenses which
arise in defense thereof. In such event, the Indemnifying Party shall not have
the right to direct the defense of such action, claim, litigation, proceeding or
investigation on behalf of the Indemnified Party.

            (d) If the indemnification provided for in this Section 4.08 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
herein, then the Indemnifying Party, in lieu of indemnifying the Indemnified
Party, shall contribute to the amount paid or payable by such Indemnified Party
with respect to such loss, liability, claim, damage or expense in the proportion
that is appropriate to reflect the relative fault of the Indemnifying Party and
the Indemnified Party 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 the Indemnified Party shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of 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 4.09. INFORMATION BY HOLDERS. Each Holder of Registrable
Securities included in any registration shall furnish to SCC such information
regarding such holders and the distribution proposed by such holder as SCC may
request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Article IV.

      Section 4.10. RULE 144 REPORTING. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Registrable Securities without registration, SCC
shall use its reasonable best efforts to:

            (a) Make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

            (b) File with the Commission in a timely manner all reports and
other documents required of SCC under the Securities Act and the Exchange Act;
and

            (c) Furnish to any Holder upon request, a written statement as to
its compliance with the reporting requirements of Rule 144 and of the Securities
Act and the Exchange Act, a copy of the most recent annual or quarterly report
of SCC, and such other reports and documents of SCC and other information in the
possession of or reasonably

                                     -16-
<PAGE>
obtainable by SCC as a Holder may reasonably request in availing itself of any
rule or regulation of the Commission allowing a Holder to sell any such
securities without registration.

      Section 4.11. TERMINATION OF REGISTRATION RIGHTS. The rights of each
Holder under this Article IV shall terminate at such time as such Holder's
Registrable Securities may be sold without registration in reliance upon Rule
144(k) promulgated under the Securities Act; PROVIDED, HOWEVER, that this
Section 4.11 shall not apply to any Holder who owns more than four percent (4%)
of the outstanding SCC Shares until such time hereafter as the Holder owns less
than four percent (4%) of the outstanding SCC Shares.

      Section 4.12. SCC'S OPTION TO PURCHASE RESTRICTED SECURITIES INSTEAD OF
REGISTRATION. Notwithstanding anything in this Article IV to the contrary, in
lieu of proceeding with the registration of all or any portion of the Restricted
Securities of any Holder otherwise required hereunder, SCC, by written notice
given to such holder prior to the effectiveness of any such registration, may
elect to purchase, or cause any Affiliate to purchase, such Restricted
Securities at a price per share, payable in cash, equal to the SCC Fair Market
Value Per Share.

                                   ARTICLE V
                           MISCELLANEOUS PROVISIONS

      Section 5.01. BOARD OF DIRECTORS OF THE COMPANY. At such time as SCC may
request, in its discretion, each of the Stockholders agrees to vote its or his
Shares in favor of, and to otherwise cooperate with SCC in causing, the size of
the Board of Directors of the Company to be increased to seven (7) directors,
and the filling of the vacancies created by any such increase with persons
designated by SCC, provided that the foregoing shall not limit SCC's own
authority to directly or indirectly cause the foregoing to occur without such
cooperation. The foregoing provision shall be of no further force or effect in
the event that SCC ceases to own, directly or indirectly, a majority interest in
the Company as a result of the exercise by the Senior Lender or the Subordinated
Lender, as the case may be, of its rights under the Senior Loan Agreements or
the Subordinated Loan Agreements (including, without limitation, the Stock
Pledge Agreement), respectively.

      Section 5.02. PARTIES TO AGREEMENT. Every stockholder or holder of an
Option of the Company, or holder of Restricted Securities, shall, at the option
of the Company's or SCC's Board of Directors, be required to become a party to
this Agreement by signing or causing to be signed on its behalf and delivering
to the Company and SCC an Instrument of Accession if such Person is not already
a party to this Agreement. Except as set forth herein, no Person shall become an
owner of record of any Shares through a subsequent transfer from any Stockholder
unless and until the Company and SCC have received an executed Instrument of
Accession signed by such Person and, in the case of a transferee other than a
Permitted Transferee, such Instrument of Accession shall have been accepted by
the Company and SCC. No transfer of Shares shall be effective for any purpose
unless and until recorded on the Company's record of stockholders upon surrender
of the certificate representing such Shares, duly endorsed for transfer. Shares
shall be issued and recorded only in the name of the beneficial owner thereof or
in the name or name(s) of the trustee or nominee or trustees or nominees holding
legal title thereto for such beneficial owner on a fully disclosed basis.

      Section 5.03. SECRETARY TO RETAIN COPY. The Company agrees to cause the
Secretary of the Company, and SCC agrees to cause the Secretary, to maintain a
copy of this Agreement on file at the Company's and SCC' main office,
respectively, where it shall be available for inspection during normal business
hours by any Stockholder.

<PAGE>
      Section 5.04. AMENDMENT AND WAIVER. No modification, amendment or waiver
of any provision of this Agreement will be effective unless such modification,
amendment or waiver is approved in writing by the Company, SCC and a majority in
interest of the Shares then outstanding, and, if such modification, amendment or
waiver would affect the provisions of Article IV, by a majority in interest of
the Restricted Securities then outstanding. The failure of any party to enforce
any of the provisions of this Agreement will in no way be construed as a waiver
of such provisions and will not affect the right of such party thereafter to
enforce each and every provision of this Agreement in accordance with its terms.

      Section 5.05. SEVERABILITY. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or other jurisdiction, but his Agreement will be reformed,
construed and enforced in such jurisdiction as if such invalid, illegal or
unenforceable provision had never been contained herein.

      Section 5.06. ENTIRE AGREEMENT. Except as otherwise expressly set forth
herein, this document embodies the complete agreement and understanding among
the parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
any way.

      Section 5.07. SUCCESSORS AND ASSIGNS. This Agreement shall inure to the
benefit of and be enforceable by (i) the Company, SCC, WC Holdings and their
respective successors and assigns and (ii) the Holders and their respective
heirs, executors, administrators and permitted assigns or each of them so long
as they hold Shares or Restricted Securities or until this Agreement is
terminated.

      Section 5.08. FURTHER ACTIONS. At any time and from time to time each
party agrees, at its expense, to take such actions and to execute and deliver
such documents as reasonably may be necessary to effectuate the purposes of this
Agreement.

      Section 5.09. REMEDIES. The parties hereto will be entitled to enforce
their rights under this Agreement specifically (without posting a bond or other
security), to recover damages by reason of any material breach of any provision
of this Agreement and to exercise all other rights existing in their favor. The
parties hereto agree and acknowledge that money damages may not be an adequate
remedy for any breach of the provisions of this Agreement and that any party may
in its sole discretion apply to any court of law or equity of competent
jurisdiction for specific performance and/or injunctive relief in order to
enforce or prevent any violation of the provisions of this Agreement.

      Section 5.10. GOVERNING LAW. This Agreement shall be governed by, and
construed and enforced in accordance with and subject to, the laws of the State
of Delaware applicable to agreements made and to be performed entirely within
such State.

      Section 5.11. EMPLOYMENT. Nothing contained in this Agreement is intended
to create for any Stockholder who is employed by the Company or SCC (or any
Affiliate thereof) any right to continued employment with the Company or SCC (or
any Affiliate thereof) or employment in the same position or on the same terms
as those currently in effect.
