         4.3. Earnout. (a) No later than September 30, 2001 (the "Earnout
Determination Date"), HSA shall, for the period commencing on the date hereof
and ending on July 31, 2001 (the "Earnout Period"), deliver to the
Representative DC's audited consolidated statements of operations ("Earnout
Period Financial Statement"), which financial statement shall have been prepared
in accordance with GAAP applied on a consistent basis throughout the periods
covered thereby and reviewed by Pricewaterhouse Coopers LLP, HSA's independent
accountants ("PWC"). Concurrently with the delivery of the Earnout Period
Financial Statement, HSA shall deliver to the Representative a notice (the
"Earnout Notice") indicating the Earnout Market Value (as defined in Section
4.3(b) below), if any, as determined by HSA in good faith based on the Earnout
Period Financial Statement (the "Earnout Determination"). At the request and
expense of the Representative, HSA shall permit independent accountants
designated by the Representative to have access to the accounting personnel of
PWC used by HSA to perform such review. The Earnout Determination shall become
final (the "Final Earnout Determination") thirty (30) days after the Earnout
Notice is so delivered by HSA unless the Representative sets forth any objection
thereto in a written notice to HSA, which notice shall include the basis for the
objection to the Earnout Determination and the Representative's own
determination of the Earnout Market Value during such thirty (30) day period, in
which event the parties shall endeavor in good faith to resolve such dispute
within fifteen (15) days after such notice and failing such resolution to
mutually agree upon a partner of a Big Five accounting firm (other than a firm
which represents HSA) (the "Accounting Firm") to resolve such dispute promptly,
and in no event later than 30 days after the 15-day dispute resolution period,
and whose determination shall be final and conclusive. If the parties cannot
agree on the selection of the Accounting Firm, or the selected Accounting Firm
declines to accept its appointment as the Accounting Firm and the parties cannot
agree on the selection of another independent accounting firm to act as the
Accounting Firm, either party may seek Speedy Arbitration to select such a firm,
and such appointment shall be conclusive and binding on the parties. Promptly,
but within 30 days after acceptance of its appointment as the Accounting Firm,
the Accounting Firm shall take all such actions (including, without limitation,
any audit procedures) as shall be necessary to determine the remaining disputed
items and shall render a written report to the Representative and the Surviving
Corporation upon such items. During such 30 day period, the Surviving
Corporation shall afford the Accounting Firm full access to any and all of its
records and work papers related to the dispute, and the Surviving Corporation
shall use its reasonable best efforts to make available (subject to the policies
of the Surviving Corporation's accountants) any work papers of the Surviving
Corporation's accountants created in connection with the calculation of the
Earnout Market Value, and the assistance of the Surviving Corporation's
accountants, in each case, as is necessary to enable the Accounting Firm to
review the calculation of the

                                       10
<PAGE>   11

Earnout Market Value. The Accounting Firm's decision shall be final, conclusive
and binding on all parties. The parties agree to cooperate with each other and
each other's representatives and with the Accounting Firm in order that any and
all matters in dispute shall be resolved as soon as practicable. The fees and
expenses of the Accounting Firm shall be paid by HSA but borne equally by HSA
and the Shareholders and, accordingly, the Earnout Market value shall be reduced
by an amount equal to fifty percent (50%) of such expenses.

Earnout Period (expressed as a percentage of $11,000,000), and, the

           Less than 95% but greater than or                         90%

           Less than 75%                                              0%
</TABLE>

provided, however, that solely for purposes of determining the revenue level
achieved and the calculation of the Earnout Market Value, DC shall be credited
with 2.273 times the amount of cash DC collects between the date hereof and
August 25, 2000 as revenues earned in first quarter 2000 but not collected, as
of the date hereof, as reflected on Section 4.3 of the Disclosure Schedule.

               (c) Subject to Section 4.4 below, if there is any Earnout Market
Value, within five (5) business days after HSA's calculation of the Earnout
Determination, HSA shall issue to each Shareholder that number of additional HSA
Common Shares (the "Earnout Shares") equal to the number of DC Shares listed
opposite such Shareholder's name on Section 4.3 of the Disclosure Schedule,
multiplied by the Earnout Exchange Ratio. The "Earnout Exchange Ratio" shall be
the quotient obtained by dividing (i) the Earnout Market Value by the number of
DC Shares outstanding as of the date hereof, by (ii) the Earnout Share Price.
Subject to Section 4.4. below, if additional Earnout Shares are due to be issued
as a result of the Final Earnout Determination, HSA shall have an additional
five (5) business days after the determination to issue such shares.
Notwithstanding anything contained herein to the contrary, if such Earnout Share
Price would require HSA to issue a number of Earnout Shares which would require
HSA to

                                       11
<PAGE>   12

obtain shareholder approval pursuant to NASD Rule 4460(i)(1)(C), then HSA
shall be required to issue the greatest number of Earnout Shares which does not
require such approval.

               (d) In addition to the calculation provided in paragraph (b) of
this Section 4.3, the number of Earnout Shares and the Earnout Share Price shall
be adjusted to reflect fully the effect of any reclassification, stock split,
reverse stock split, stock dividend, reorganization or recapitalization or other
similar event with respect to HSA Common Stock occurring after the Effective
Time and prior to the Earnout Payment Date. For purposes hereof, the Earnout
Shares and the Share Consideration shall be collectively referred to as the
"Merger Consideration."

         4.4. Earnout Reduction For Losses. (a) The Earnout Market Value shall
be subject to reduction in accordance with the provisions of Section 4.4(b)
below for any losses, threatened losses, damages, deficiencies, claims,
liabilities, obligations, suits, actions (including any Tax audits, examinations
or other proceedings), fees, costs or expenses of any nature whatsoever
(including, without limitation, all reasonable fees and disbursements of
counsel) (collectively, "Losses") incurred or suffered by HSA and Acquisition
and each of their respective officers, directors, employees, agents and advisors
(each, an "HSA Party") arising or resulting from (x) any breach of any
representation and warranty of DC which is contained in this Agreement or any
Schedule, Exhibit, agreement or certificate delivered pursuant hereto (provided
that (I) for the purposes hereof, any breach of any representation or warranty
shall be deemed not to contain, and shall be determined without regard to any
qualification related to, materiality, Material Adverse Effect or Knowledge
contained in such representation or warranty (II) for the purposes of
determining Losses with respect to breaches of representations and warranties,
only those Losses which individually exceed $2,500 shall be considered (such
Losses are referred to herein as "Limited Losses"); (III) except as provided in
(IV) below, there shall be no reduction in the Earnout Market Value for Limited
Losses until the aggregate amount of such Limited Losses exceeds $150,000 (the
"Threshold"); (IV) the Earnout Market Value shall be reduced in an amount equal
to an amount by which Limited Losses in the aggregate exceed the Threshold,
except that if Limited Losses in the aggregate exceed $250,000, the Earnout
Market Value shall be reduced to account for all Limited Losses in the
aggregate, including those below the Threshold; (y) any breach or
non-fulfillment of or any failure to perform any of the covenants, agreements or
undertakings of DC which are contained in or made pursuant to this Agreement or
any Schedule, Exhibit, agreement or certificate delivered pursuant hereto; or
(z) any Taxes of or imposed upon DC or any of its Subsidiaries relating to or
arising from periods (or portions thereof) ending on or prior to or including
the Closing Date (except, with respect to Taxes not yet due, to the extent of
the accruals therefor reflected in the Financial Statements).

         (b) In the event of the occurrence, at any time between the Effective
Time and the date which is twelve months from the date of the Effective Time, of
an event which an HSA Party asserts constitutes a Loss (an "HSA Claim"), HSA
shall provide prompt notice of such event (a "Loss Notice") to the
Representative. Such Loss

                                       12
<PAGE>   13

Notice shall detail the circumstances of the Loss, the aggregate amount of the
Loss and the corresponding reduction in Earnout Market Value based on such Loss.
Upon the written request of the Representative, HSA shall provide the
Representative with copies of all written documentation related to the Loss. The
reduction in Earnout Market Value pursuant to the Loss Notice shall become final
(the "Final Loss Determination") thirty (30) days after the Loss Notice is so
delivered by HSA unless the Representative sets forth any objection thereto in a
written notice to HSA, which notice shall include the basis for the
Representative's objection to the Loss and the corresponding reduction in the
Earnout Market Value during such thirty (30) day period, in which event the
parties shall endeavor in good faith to resolve such dispute within fifteen (15)
days after such notice, and failing such resolution, to submit their dispute to
an arbitrator (the "Arbitrator") and whose determination as to the Final Loss
Determination shall be final and conclusive in an arbitration administered by
the American Arbitration Association under its Commercial Arbitration Rules. The
Arbitrator's decision shall be final, conclusive and binding on all parties and
the judgment or award rendered may be entered in any court having jurisdiction
thereof. The fees and expenses of the Arbitrator shall be paid by HSA but borne
equally by HSA and the Shareholders. Accordingly, the Earnout Market Value shall
be reduced by an amount equal to fifty percent (50%) of such expenses.

         (c) If the event giving rise to the Loss involves the claim of any
third party (a "Third-Party Claim"), HSA shall assume sole control of the
defense, settlement, adjustment or compromise of such claim, provided, however,
that HSA shall diligently pursue the defense of any such Third Party Claim.

         (d) In the event that upon the Final Earnout Determination, a Loss
Notice has been delivered to the Representative, but the Final Loss
Determination has not yet occurred, pending such determination, the Earnout
Market Value shall be reduced by the amount of the Loss set forth in the Loss
Notice and a corresponding reduction shall be made in the number of Earnout
Shares issued to the Shareholders (the "Retained Earnout Shares"). Promptly upon
the occurrence of the Final Loss Determination, HSA shall, subject to reductions
for arbitration fees pursuant to Section 4.4(b) above, deliver to Shareholders
such number of Retained Earnout Shares, if any, as shall be necessary to comply
with the Final Loss Determination. HSA shall not be required to issue any
Retained Earnout Shares prior to the Final Loss Determination, and HSA shall not
incur any liabilities with respect to the non-issuance of any Retained Earnout
Shares pending the Final Loss Determination.

         4.5. Fractional Shares of HSA Common Stock. No certificates
representing fractional shares of HSA Common Stock shall be issued upon
surrender of any DC Share Certificates. In lieu of any fractional shares of HSA
Common Stock, there shall be paid to the holder of DC Shares who otherwise would
be entitled to receive a fractional share of HSA Common Stock an amount of cash
(without interest) determined by multiplying such fraction by the Base Exchange
Ratio or the Earnout Exchange Ratio, as the case may be.

                                       13
<PAGE>   14

         4.6. Withholding Rights. Each of the Surviving Corporation and HSA
shall be entitled, or shall be entitled to cause the Transfer Agent, to deduct
and withhold from the Merger Consideration otherwise payable pursuant to this
Agreement to any holder of DC Shares such amounts as it is required to deduct
and withhold with respect to the making of such payment under the Code and the
rules and regulations promulgated thereunder, or any provision of a Tax law. To
the extent that amounts are so withheld by the Surviving Corporation, HSA or the
Transfer Agent, as the case may be, such amounts shall be treated for all
purposes of this Agreement as having been paid to the holder of the DC Shares in
respect to which such deduction and withholding was made by the Surviving
Corporation or HSA, as the case may be.

         4.7. Effect on Options to Acquire DC Shares. (a) As soon as
practicable, following the Effective Time (in accordance with standard
procedures of the Compensation Committee of HSA's Board of Directors and HSA's
past practices with respect to granting options to its employees) each employee
of DC as of the Effective Time shall be granted an option to purchase HSA Shares
(an "HSA Option") for each outstanding and unexpired option to purchase DC
Shares (a "DC Option"), which DC Options are listed opposite such employee's
name on Section 4.7(a) of the Disclosure Schedule, whether vested or unvested,
shall (except to the extent exercised prior to the Effective Time) on the same
terms and subject to the same conditions as applicable to similarly situated
employees of HSA under the HSA 1999 Stock Option Plan pursuant to which plan
such HSA Option shall be granted (including term and exercisability), and such
HSA Option shall be an option to purchase the same number of whole shares of HSA
Common Stock as the holder of such DC Option would have been entitled to receive
pursuant to this Agreement (assuming solely for the purposes of this calculation
that the Earnout Market Value was equal to $25,000,000) had such holder
exercised such DC Option in full for DC Shares immediately prior to the
Effective Time, at a price per share of HSA Common Stock equal to the per share
exercise price equal to the closing price of HSA Common Stock on the date
immediately prior to the date of the grant.

         (b) Each of the non-employee holders of DC Options listed in Section
4.7(b) of the Disclosure Schedule shall receive a warrant to receive HSA Common
Stock substantially in the form attached hereto as Exhibit K. Such warrant shall
permit the holder thereof to purchase the number of shares of HSA Common Stock
equal to the number of shares of HSA Common Stock each such holder would have
been entitled to receive pursuant to this Agreement (assuming solely for the
purposes of this calculation that the Earnout Market Value was equal to
$25,000,000) had such holder exercised the number of DC Options listed opposite
such holder's name on Schedule 4.7(b) of the Disclosure Schedule prior to the
Effective Time. The exercise price per share pursuant to the warrant shall be
equal to the closing price of a share of HSA Common Stock on the Closing Date on
the Nasdaq National Market (as reported in the New York City edition of the Wall
Street Journal or, if not reported thereby, another nationally recognized
source).

         (c) At or prior to the Effective Time, HSA shall take all corporate
action necessary to reserve for issuance a sufficient number of shares of HSA
Common

                                       14
<PAGE>   15

Stock for delivery upon exercise of such DC Options in accordance with this
Section 4.7. Any option or stock plan with respect to DC Shares existing
immediately prior to the Effective Time shall terminate as of the Effective Time
with respect to any future grants thereunder. Prior to any grant of an HSA
Option pursuant to Section 4.7(a) above, or the grant of a warrant pursuant to
Section 4.7(b) above, any DC Option held by the recipient of the HSA Option or
warrant, as the case may be, shall be terminated.

                                   ARTICLE 7

                  REPRESENTATIONS AND WARRANTIES CONCERNING DC

         DC represents and warrants to Acquisition and HSA that the statements
contained in this Article 7 are correct and complete as of the date hereof,
except as set forth in the disclosure schedule delivered by DC to Acquisition
and HSA on the date hereof (the "Disclosure Schedule"), which Disclosure
Schedule shall identify the specific Sections of this Article 7 as to which the
exception or disclosure applies. Nothing in the Disclosure Schedule shall be
deemed adequate to disclose an exception to a representation or warranty made
herein, however, unless the Disclosure Schedule reasonably identifies the
exception. Without limiting the generality of the foregoing, the mere listing
(or inclusion of a copy) of a document or other item shall not be deemed
adequate to disclose an exception to a representation or warranty made herein
(unless the representation or warranty has to do with the existence of the
document or other item itself). The Disclosure Schedule will be arranged in
paragraphs corresponding to the lettered and numbered paragraphs contained in
this Article 7.

         7.1. Organization, Qualification, and Corporate Power. Each of DC and
its Subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of the states set forth in Section 7.1(a) of the
Disclosure Schedule. Each of DC and its Subsidiaries is duly authorized to
conduct business and is in good standing under the laws of each jurisdiction,
except where failure to be so qualified could not be reasonably expected to have
a Material Adverse Effect on DC, and each such jurisdiction is set forth in
Section 7.1(a) of the Disclosure Schedule. Each of DC and its Subsidiaries has
full corporate power and authority necessary to carry on the businesses in which
it is engaged and to own and use the properties owned and used by it. Section
7.1(b) of the Disclosure Schedule lists the directors and officers of DC and
each Subsidiary. DC has provided a description of each directors' and officers'
business experience during the past five (5) years and a description of the
services provided by such person to DC. Each of DC and its Subsidiaries has
delivered to Acquisition and HSA correct and complete copies of the articles of
incorporation and bylaws (such documents and, as may be applicable, any similar
organizational documents with respect to any Person referred to in

                                       17
<PAGE>   18

this Agreement, being referred to herein as the "Organizational Documents") of
each of DC and its Subsidiaries, respectively (as amended to date). The minute
books (containing the records of meetings of the stockholders, the board of
directors and any committees of each of DC and its Subsidiaries), the stock
certificate books and the stock record books of each of DC and its Subsidiaries
in the forms in which they have been provided to HSA are correct and complete,
except for the minutes of DC Board or committee meetings which have not been
finalized. Neither DC nor any of its Subsidiaries is in default under or in
violation of any provision of its Organizational Documents.

         7.2. Capitalization. The entire authorized capital stock of DC consists
of 100,000,000 shares of common stock, $.0001 par value, of which 30,364,441
shares were issued and outstanding as of June 23, 2000. All of the issued and
outstanding DC Shares have been duly authorized, are validly issued, fully paid,
and nonassessable, and are held of record by the Shareholders as set forth in
Section 7.2 of the Disclosure Schedule. Except as set forth in a list (including
exercise prices, dates of grant and expiration, and number granted to each
holder thereof, if applicable) in Section 7.2 of the Disclosure Schedule, there
are no outstanding or authorized options, warrants, purchase rights, pre-emptive
rights, subscription rights, conversion rights, exchange rights or other
contracts or commitments that could require DC to issue, sell, or otherwise
cause to become outstanding any of its capital stock. There are no outstanding
or authorized stock appreciation, phantom stock, profit participation or similar
rights with respect to DC. There are no outstanding contractual obligations of
the Company or any of its Subsidiaries to repurchase, redeem or otherwise
acquired any shares or other capital stock of the Company or any of its
Subsidiaries to provide funds to make any investment (in the form of a loan,
capital contribution or otherwise) in any Subsidiary. There are no voting
trusts, proxies, or other agreements or understandings with respect to the
voting of the DC Shares. None of the outstanding DC Shares are subject to any
forfeiture or similar restriction in connection with the termination of
employment of any holder thereof with DC.

         7.3. Authorization of Transaction. DC has full power and authority
(including full corporate power and authority) to execute and deliver this
Agreement and to perform its obligations hereunder. The execution and delivery
of this Agreement and the consummation of the transactions contemplated hereby
have been duly authorized by all requisite corporate action on the part of DC
and the Board of Directors of DC (the "DC Board") has resolved (i) to adopt this
Agreement (ii) recommend that the Shareholders approve and adopt this Agreement
and the Merger. The DC Board has directed that this Agreement be submitted to
the Shareholders as required pursuant to Section 607.1103 of the FBCA. The
affirmative vote of a majority of the DC Shares outstanding is the only vote
necessary to approve and adopt this Agreement and the transactions contemplated
hereby, including the Merger (the "Requisite Vote"). This Agreement constitutes
the valid and legally binding obligation of DC, enforceable in accordance with
its terms and conditions, except as such enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
creditors' rights generally and to general principles of equity. DC is not
required to give any notice

                                       18
<PAGE>   19

to, make any filing with, or obtain any Licenses and Permits of any Governmental
Authority in order to consummate the transactions contemplated by this
Agreement, except in connection with the filing of the Articles of Merger with
the Florida Secretary of State and applicable state securities laws.

         7.4. Noncontravention. Neither the execution and the delivery of this
Agreement, nor the consummation of the transactions contemplated hereby, will

         (i) violate any law, constitution, statute, regulation, rule,
         injunction, judgment, order, decree, ruling, charge or other
         restriction of any Governmental Authority to which DC or any of its
         Subsidiaries is subject or any provision of the Organizational
         Documents of DC or any of its Subsidiaries or

         (ii) except as otherwise set forth in Section 7.4 of the Disclosure
         Schedule, result in a breach of, constitute a default under, result in
         the acceleration of, create in any party the right to accelerate,
         terminate, modify, cancel, or require any notice, receive any
         additional consideration or payments under, any agreement, contract,
         lease, license, instrument, or other arrangement to which DC or any of
         its Subsidiaries is a party or by which it is bound or to which any of
         its assets is subject (or, except pursuant to the Secured Note, result
         in the imposition of any Security Interest upon any of its assets), the
         result of which could reasonably result in a Material Adverse Effect on
         DC or prevent the consummation of the Merger or the other transactions
         contemplated hereby.

         7.5. Title to Assets. Except as set forth in Section 7.5 of the
Disclosure Schedule, each of DC and its Subsidiaries has good and marketable
title to, or a valid leasehold interest in, the properties and assets used by
it, located on its premises, or shown on the Most Recent Balance Sheet or
acquired after the date thereof, free and clear of all Security Interests
(except those Security Interests imposed pursuant to the Secured Note), except
for properties and assets disposed of in the Ordinary Course of Business since
the date of the Most Recent Balance Sheet.

         7.6. Subsidiaries. (a) Sections 7.6 of the Disclosure Schedule sets
forth, as of the date hereof, a true and complete list of all of the
Subsidiaries of DC, including the jurisdiction of incorporation or organization
of each Subsidiary and the percentage of each Subsidiary's outstanding capital
stock owned by DC, another Subsidiary of DC or by any other Person.

         (b) All of the outstanding shares of capital stock of each Subsidiary
have been validly issued and are fully paid and nonassessable and are owned
beneficially and of record by DC, free and clear of all encumbrances. At the
Closing, DC will not, directly or indirectly, own any capital stock of or other
equity interests in any corporation, partnership or other Person other than the
Subsidiaries listed in Section 7.6

                                       19
<PAGE>   20

of the Disclosure Schedule, and neither DC nor any of its Subsidiaries is a
member of or participant in a partnership, joint venture or similar Person.

         7.7. Financial Statements. DC has delivered (collectively, the
"Financial Statements") to HSA its (i) audited condensed/consolidated balance
sheets and statements of income, changes in shareholders' equity and cash flows
as of and for the fiscal years ended December 31, 1997, 1998 and 1999, and (ii)
unaudited condensed/consolidated balance sheet and statement of income (the
"Most Recent Financial Statements") as of and for the three-month period ended
March 31, 2000 (the "Most Recent Fiscal Month End"). The Financial Statements
are attached hereto as Exhibit 7.7. The Financial Statements (including the
notes thereto) have been prepared in accordance with GAAP applied on a
consistent basis throughout the periods covered thereby, present fairly the
consolidated financial condition of DC and its Subsidiaries as of such dates and
the consolidated results of operations of DC and its Subsidiaries for such
periods, subject, in the case of the Most Recent Financial Statements, to normal
year-end adjustments and the absence of notes thereto, and are consistent with
the books and records of DC and its Subsidiaries (which books and records are

         7.23. Employee Benefits.

         (a) Section 7.23(a) of the Disclosure Schedule lists each Company Plan.
Neither DC, any Subsidiary nor any trade or business (whether or not
incorporated) which is or has ever been under common control, or which is or has
ever been treated as a single employer, with any of them under Section 414(b),
(c), (m) or (o) of the Code ("ERISA Affiliate") has ever contributed or has ever
been obligated to contribute to any Employee Pension Benefit Plan subject to
Title IV of ERISA or to any Multiemployer Plan.

         (b) The Company Plans have been maintained, in all material respects,
in accordance with their terms and with all provisions of ERISA, the Code
(including rules and regulations thereunder). The Company Plans intended to
qualify under Section 401 of the Code are so qualified and the trusts maintained
pursuant thereto are exempt from federal income taxation under Section 501 of
the Code, and nothing has occurred with respect to the operation of the Company
Plans which could cause the loss of such qualification or exemption or the
imposition of any material liability, penalty or tax under ERISA or the Code.

         (c) All required reports and descriptions (including Form 5500 Annual
Reports, Summary Annual Reports, and Summary Plan Descriptions) have been filed
(or appropriate extensions have been applied for) or distributed appropriately
with respect to each such Employee Benefit Plan. The requirements of Part 6 of
Subtitle B of Title 1 of ERISA and of Code Section 4980B have been met with
respect to each group health plan (as defined in Section 607(1) of ERISA and
Section 4980B(g)(2) of the Code).

         (d) All contributions premiums or other payments (including all
employer contributions and employee salary reduction contributions) which are
due have been paid to each Company Plan and all contributions for any period
ending on or before the Closing Date which are not yet due have been paid to
each such plan or accrued in accordance with the past custom and practice of
each of DC and its Subsidiaries.

         (e) Each Company Plan which is an Employee Pension Benefit Plan meets
the requirements of a "qualified plan" under Code Section 401(a) and, in the
case of all other qualified plans, a favorable determination letter has been
received by the plan within the last two years from the Internal Revenue
Service.

         (f) With respect to each Company Plan, each of DC and its Subsidiaries
has delivered to Acquisition and HSA correct and complete copies, to the extent
applicable, of the plan documents and any amendments thereto, summary plan
descriptions, the most recent determination letter received from the Internal
Revenue Service, the most recent Form 5500 Annual Report and all schedules and
attachments thereto, and all related trust agreements, insurance contracts, and
other funding agreements which implement each such Company Plan.

<PAGE>   32

         (g) There have been no Prohibited Transactions with respect to any such
Company Plan. No Fiduciary has any Liability for breach of fiduciary duty or any
other failure to act or comply in connection with the administration or
investment of the assets of any such Company Plan. No action, suit, proceeding,
hearing, or investigation with respect to the administration or the investment
of the assets of any such Company Plan (other than routine claims for benefits)
is pending or threatened and, none of the Shareholders or DC has any Knowledge
of any Basis for any such action, suit, proceeding, hearing, or investigation.

         (h) Neither DC nor any of its Subsidiaries maintains or contributes to,
has ever maintained or contributed to and has ever been required to contribute
to, any Company Plan providing post-retirement, medical, health or life
insurance or other welfare-type benefits for current or future retired or
terminated employees, their spouses, or their dependents (other than in
accordance with Code Section 4980B).

         (i) Neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby will (i) result in any
payment becoming due to any employee (current, former or retired) of DC or any
of its Subsidiaries, (ii) increase any benefits otherwise payable under any
Company Plan or (iii) result in the acceleration of the time of payment or
vesting of any such benefits under any such plan.

         (j) No stock or other security issued by DC forms or has formed a
material part of the assets of any Company Plan.

         (k) Any individual who performs services for DC or any of its
Subsidiaries (other than through a contract with an organization other than such
individual) and who is not treated as an employee of DC or any of its
Subsidiaries for federal income tax purposes by DC or any of its Subsidiaries is
not an employee for such purposes.

         7.24. Guaranties. Neither DC nor any of its Subsidiaries is a guarantor
and otherwise is not liable for any Liability or obligation (including
indebtedness) of any other Person.

in Section 7.26 of the Disclosure Schedule, DC believes that the relationships
of each of DC and its Subsidiaries with its existing customers and suppliers are
sound. The Shareholders and DC do not know of any written or oral communication,
fact, event or

accounted for over 1% of total net sales of such company for its most recently
completed fiscal year; or

               (ii) any current supplier to DC or any of its Subsidiaries of
items essential to the conduct of the business, which items cannot be replaced

Material Adverse Effect on DC or any of its Subsidiaries.

has retained all sales personnel employed in connection with the operation of
its businesses and (B) no customer (or group of customers) purchasing in the
aggregate of $200,000 in products and services on a yearly basis has terminated
its relationship with DC or any of its Subsidiaries.

         7.27. Bank Accounts. Sections 7.27 of the Disclosure Schedule sets

of or consultant to DC, any of its Subsidiaries or any of its Affiliates.

         7.29. Change in Control. Except as set forth in Section 7.29 of the
Disclosure Schedule, neither DC nor any of its Subsidiaries is a party to any
contract or arrangement which contains a "change in control," "potential change
in control" or similar provision, and the consummation of the transactions
contemplated hereby shall not (either alone or upon the occurrence of additional
acts or events) result in any payment or payments becoming due from DC or any of
its Subsidiaries to any person or give any person the right to terminate or
alter the provisions of any agreement to which DC and any of its Subsidiaries is
a party.

         7.30. Brokers' Fees. Except as set forth in Section 7.30 of the
Disclosure Schedule, neither DC, any of its officers, directors or employees,
nor any Shareholder, has any Liability or obligation to pay any fees or
commissions to any broker, finder or agent with respect to the transactions
contemplated by this Agreement.

shall expire at or prior to the Effective Time, and the DC Board has taken no

                                       33
<PAGE>   34

action, the effect of which would cause, permit or result in the survival of
such options following the Effective Time.

         7.32. DC Affiliates. Section 7.32 of the Disclosure Schedule sets forth
a true and correct list of all Affiliates of DC.

contained in Article 8, such Secured Note shall constitute a fully disclosed
exception, whether or not particularly referenced in each case.

                                   ARTICLE 10

    SHAREHOLDER REPRESENTATIVE; CONDUCT OF BUSINESS DURING THE EARNOUT PERIOD

         10.1. Representative. The representative of the Shareholders (the
"Representative") shall be Gary Allen, or such other representative as may be
hereafter appointed by a majority in interest of the Shareholders. The
Representative shall act on each Shareholder's behalf with respect to all of the
transactions contemplated by this Agreement, including, without limitation, the
Final Earnout Determination and any Final Loss Determination. The Representative
shall take any and all actions which the Representative believes are necessary
or appropriate under this Agreement for and on behalf of each Shareholder, as
fully as if such Shareholder were acting on his or her own behalf, including,
without limitation, executing on the Shareholders' behalf all agreements and
documents required to consummate the transactions contemplated by this
Agreement, conducting negotiations or arbitrations with HSA and its
representatives regarding the Final Earnout Determination and any Final Loss
Determination, taking any and all other actions specified in or contemplated by
this Agreement and engaging counsel, accountants or other representatives in
connection with the foregoing matters. HSA shall have the right to rely upon all
actions taken or omitted to be taken by the Representative pursuant to this
Agreement, all of which actions or omissions shall be legally binding upon the
Shareholders. The Representative, acting pursuant to this Section 10.1, shall
not be liable to any Shareholder for any act or omission, except in connection
with any act or omission that was the result of the Representative's bad faith
or gross negligence.

         10.2. Conduct of Surviving Corporation from the Date of Signing to the
Earnout Date. From and after the signing of this Agreement through the Earn Out
Date, DC's management shall operate its business substantially in accordance
with the financial projections prepared by DC and attached hereto as Exhibit C
(the "DC Financial Projections") with a view towards achieving the full Earn Out
Market Value; it being understood that the revenue and expense targets for DC
set forth in the DC Financial Projections do not take into account any
acquisitions or any direct management or cross-marketing assistance from HSA,
but do take into account an aggregate of $5 million of working capital to be
provided to DC by HSA, less the aggregate amount funded by HSA under the Secured
Note (the "Working Capital Commitment"). HSA agrees that DC's officers shall
have the authority and discretion to carry out the business and activities of DC
in accordance with the DC Financial Projections. DC shall consult with HSA in
respect of its business and operations, and shall furnish monthly financial and
operations reports to HSA within 20 days of the end of each month. In the event
and to the extent DC's monthly financial results reflect a revenue, operating
expense and/or EBITDA variance of 10% or more from the DC Financial Projections,
HSA shall have the option, in its sole and absolute discretion, to modify the
level of Working Capital Commitment and/or require DC to modify its business
practices in view of such changed business circumstances.

                                       44
<PAGE>   45

         For the purpose of calculating the "Earnout Period Revenue" levels set
forth on the table in Section 4.3(b) hereof, (i) DC shall not be charged with
expenses attributable to servicing third party business(es) acquired by HSA or
DC or new business obtained through HSA sales channels (i.e., sales originating
by or through HSA's marketing and field operations organizations) (either
referred to as a "Third Party Business"); (ii) DC shall be credited with 20% of
the revenue (net of appropriate reserves) generated by DC from Third Party
Business, it being understood and agreed that HSA shall not be obligated to
affirmatively cause or support such acquisitions or sales; and (iii) HSA may in
its sole and absolute discretion transition its pre-existing hosting customers
to DC and DC shall be credited with 5% of revenue generated therefrom. To the
extent DC, with the consent of HSA, acquires a Third Party Business from
proceeds of the Working Capital Commitment, such acquired Third Party Business's
operating results shall be charged towards the Earnout calculation.

termination (except for such fees and expenses incurred in connection with the
collection thereof) in connection with this Agreement and the transactions
contemplated hereby and (3) any other amounts owed by DC or its affiliates to

Agreement shall be valid unless the same shall be in writing and signed by HSA,
DC and the Representative. No waiver by any party of any default,
misrepresentation or breach of warranty or covenant hereunder, whether

breached shall not detract from or mitigate the fact that the party is in breach
of the first representation, warranty or covenant.

Schedules identified in this Agreement are incorporated herein by reference and

         denominated in Dollars (the "Letters of Credit") for the account of the
         Borrower or for the joint account of the Borrower and any of its
         Subsidiaries from time to time on any Business Day from the date of the
         initial Advance until the Revolving Commitment Maturity Date in an
         aggregate maximum amount (assuming compliance with all conditions to
         drawing) not to exceed, at any time outstanding, the lesser of (i)
         $30,000,000 (the "Letter of Credit Facility") and (ii) the sum of (A)
         the Revolving Credit Commitment, minus (B) the aggregate principal
         amount of Revolving Credit Advances and Swing Line Advances then
         outstanding.

         (g) Article 2 of the Credit Agreement is hereby amended by adding a new
Section 2.17 thereto to read as follows:

                  Section 2.17 Revolving Credit Commitment Increase.

                  (a) Amount and Timing of Increases. Upon written request by
         the Borrower to the Administrative Agent not less than ten Business
         Days prior to the proposed effective date of the proposed increase (or,
         in the case of each proposed Lender, such lesser notice as any proposed
         Lender is willing to accept), subject to the further terms and
         conditions set forth below, the Borrower shall be entitled to increase
         the Revolving Credit Commitment not more than three times, in an
         aggregate amount for such increases not to exceed $30,000,000. Each of
         the proposed increases shall be in an aggregate minimum amount of
         $5,000,000 and $5,000,000 multiples thereof.

                  (b) Mechanics of Increases. Upon the Agent's receipt of the
         notice referred to in Section 2.17(a), the Agent shall immediately make
         an offer to the Lenders to elect to participate in such increase. Each
         Lender electing to participate in such Revolving Credit Commitment
         increase shall commit to an amount not less than $2,000,000 but shall
         accept any allocation amount designated by the Borrower and the
         Administrative Agent that is equal to or less than its proposed portion
         of the Revolving Credit Commitment increase. Notwithstanding anything
         herein or in any other Loan Document to the contrary, the Borrower and
         the Administrative Agent may agree to add other creditors in connection
         with any such proposed increase (without any further notice obligations
         to the existing Lenders and without retriggering the timing
         requirements set forth in Section 2.17(a)) if one or more of the
         existing Lenders having a Revolving Credit Specified Percentage do not
         elect to increase their respective portions of the Revolving Credit
         Commitment in an amount equal to the requested Revolving Credit
         Commitment increase within five Business Days after the Borrower
         requests such increase pursuant to Section 2.17(a). If requested, each
         Lender (including any new Lenders party hereto) shall upon the
         surrender of any then-existing Revolving Credit Note held by such
         Lender receive a new Revolving Credit Note evidencing its Revolving
         Credit Specified Percentage, as adjusted.

                  (c) Conditions to Increase. The following conditions to the
         increase of the Revolving Credit Commitment shall have been satisfied
         or waived to the Administrative Agent's reasonable satisfaction:

                                      -3-
<PAGE>   4

                           (i) On any date of proposed increase in the Revolving
                  Credit Commitment, the representations and warranties
                  contained in Article IV hereof are true and correct on such
                  date in all material respects, as though made on and as of
                  such date, except to the extent expressly made only as of a
                  prior date;

                           (ii) On any date of a proposed increase in the
                  Revolving Credit Commitment, no Default or Event of Default
                  shall exist on any such date, and no Default or Event of
                  Default would result from such increase in the Revolving
                  Credit Commitment and the subsequent Revolving Credit Advances
                  to the Borrower, up to the amount of the Revolving Credit
                  Commitment (as increased);

                           (iii) The Administrative Agent shall have received a
                  certificate from the Borrower to the effect that (A) such
                  increase has received all Necessary Authorizations, if
                  necessary, and is in compliance with all material Applicable
                  Laws, (ii) no other approvals or consents from any Person are
                  required by any such Person except to the extent they have
                  been received or are immaterial, and (iii) such increase in
                  the Revolving Credit Commitment does not conflict with, or
                  result in violation of, any material agreement or instrument
                  to which the Borrower or any of its Subsidiaries, or any of
                  their respective properties, is subject;

                           (iv) The Administrative Agent shall have delivered to
                  each Lender evidence of new Revolving Credit Specified
                  Percentages and Total Specified Percentages adjusted to give
                  effect to the increase in the Revolving Credit Commitment and
                  any reallocation required in order for each Lender with a
                  Revolving Credit Specified Percentage to have a proportionate
                  share of the Revolving Credit Advances;

                           (v) Each new Lender being added to this Agreement
                  shall deliver to the Borrower and the Administrative Agent
                  documentation acceptable to the Administrative Agent
                  evidencing such new Lender's acceptance of this Agreement and
                  all the other Loan Documents in form and substance reasonably
                  acceptable to the Administrative Agent (and making such Lender
                  a party to this Agreement and the other Loan Documents);

                           (vi) The Administrative Agent on behalf of each
                  Lender shall have received all amendments to any Loan
                  Documents as the Administrative Agent shall deem reasonably
                  necessary; and

                           (vii) The Administrative Agent shall have delivered
                  to the Borrower a notice of the cost of any LIBOR breakage or
                  other costs incurred by any Lender as a result of such
                  increase and any reallocation among the Lenders, and the
                  Borrower shall pay such costs on the date of such increase in
                  immediately available funds to the Administrative Agent on
                  behalf of such Lenders in accordance with the terms of the
                  Credit Agreement.

                  (d) Additional Agreements. Each Lender shall have the right
         (but not the obligation) to increase the dollar amount of its share of
         the Revolving Credit Commitment. In connection with any increase to the
         Revolving Credit Commitment in accordance with the terms of this
         Section 2.17, each existing Lender (regardless of whether such Lender
         is participating in such increase) and the Borrower and its
         Subsidiaries agrees to execute any and all agreements reasonably
         requested by the Administrative Agent to effectuate the intent of this
         Section 2.17. Notwithstanding anything contained herein to the
