                 REPRESENTATIONS AND WARRANTIES OF PARENT

        Parent hereby represents and warrants to Company as follows:

        Section 3.1 Purchase Entirely for Own Account

        This Agreement is made with Parent in reliance upon Parent's
representation to Company, which by Parent's execution of this Agreement Parent
hereby confirms, that the Series B Preferred Stock and the Series C Preferred
Stock to be acquired by QMOC and the Common Stock issuable upon conversion
thereof will be acquired for investment for QMOC's own account, not as a nominee
or agent, and not with a view to the resale or distribution of any part thereof,
and that QMOC has no present intention of selling, granting any participation
in, or otherwise distributing the same. By executing this Agreement, Parent
further represents that QMOC does not have any contract, undertaking, agreement
or arrangement with any person to sell, transfer or grant participation to such
person or to any third person, with respect to any shares of such Series B
Preferred Stock, Series C Preferred Stock or Common Stock.

        Section 3.2 Reliance Upon Parent's Representations

        Parent understands that the Series B Preferred Stock and the Series C
Preferred Stock are not, and any Common Stock acquired on conversion thereof at
the time of issuance may not be, registered under the Securities Act on the
ground that the sale provided for in this Agreement and the issuance of
securities hereunder is exempt from registration under the Securities Act
pursuant to section 4(2) thereof, and that Company's reliance on such exemption
is based on Parent's representations set forth herein.

        Section 3.3 Accredited Investor

        Parent is an "accredited investor" within the meaning of Rule 501 of
Regulation D promulgated under the Securities Act.

        Section 3.4 Disclaimer of Warranties.

representation or warranty. EXCEPT AS SPECIFICALLY SET FORTH IN THIS AGREEMENT,
ALL REPRESENTATIONS AND WARRANTIES, EXPRESS OR IMPLIED, INCLUDING


                                      -12-
<PAGE>   16

IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE
HEREBY EXPRESSLY DISCLAIMED.

                                   ARTICLE IV

                              ADDITIONAL AGREEMENTS

        Section 4.1 Taxes

        (a) Any sales, use or transfer taxes payable by reason of the sale and
transfer of any of the ROI Assets hereunder (other than income taxes) shall be
borne by Parent.

        (b) Parent agrees to timely file all Returns relating to the Taxes
referred to in subsection (a) above, after the review and consent of Company,
such consent not to be unreasonably withheld, and shall timely remit on behalf

due.

        (c) Within 30 days after the Closing Date, Company shall propose an
allocation of the consideration and any Assumed Liabilities, to the extent of
any gain recognized to Parent under Section 351 of the Internal Revenue Code
attributable to the status of such consideration or Assumed Liabilities as
"other property" within the meaning of Section 351(b) of the Internal Revenue
Code, among the ROI Assets (the "Allocation"). Parent and Company agree to act
in accordance with the Allocation on any Tax Returns or similar filings to the
extent Parent consents to such allocation, which consent shall not be
unreasonably withheld. In the event that any Tax authority disputes the
Allocation, Parent or Company, as the case may be, shall promptly notify the
other party of the nature of such dispute.

        Section 4.2 Employees and Employee Benefits

on and after the Closing Date is referred to herein as a "Transferred Employee."

Except as provided otherwise in this Section 4.2 or the terms of any employment
agreement between Company and any Transferred Employee, the terms of each
Transferred Employee's employment with Company shall be upon such terms and
conditions as Company, in its sole discretion, shall determine. Nothing herein
expressed or


                                      -13-

implied by this Agreement shall confer upon any Transferred Employee, or legal

whatsoever, under or by reason of this Agreement.

such actions as are necessary to cause Company to adopt, as a participating
employer, the employee benefit plans that are sponsored by Parent immediately
prior to the Closing Date for the benefit of the Transferred Employees (the

hereto covenants and agrees to use its reasonable efforts to deliver or cause to
be delivered such documents and other papers and to take or cause to be taken

Laws to consummate and make effective the transactions contemplated hereby.

        Section 4.5 Bulk Sales Compliance

        Company hereby waives compliance by Parent with any applicable laws
relating to bulk transfers in connection with the transactions contemplated
hereby. Parent shall indemnify Company with respect to any failure to comply

        Section 4.6 Assignment of Contracts and Warranties

        Notwithstanding anything contained herein to the contrary, no Assumed
Contract shall be assigned contrary to law or the terms of such Assumed Contract
and, with respect to Assumed Contracts that cannot be assigned to Company at the
Closing Date, the performance obligations of Parent thereunder shall, unless not
permitted by such Assumed Contract, be deemed to be subleased or subcontracted
to Company until such Assumed Contract has been assigned. Parent and Company
shall (i) use reasonable efforts to obtain all necessary consents and (ii)
cooperate


                                      -14-

the date hereof.

        Section 4.9 Intellectual Property

register the Intellectual Property anywhere in the world.

        Section 4.10 Covenants Not To Compete

        (a) Covenant of Parent.

                (i) Parent agrees that for the period commencing on the Closing
        Date and ending on the first anniversary of the Closing Date (such
        period is hereinafter referred to as the "Restricted Period"), Parent
        shall not anywhere in North America participate or engage, directly or
        indirectly, for itself or on behalf of or in conjunction with any
        Person, whether as an employee, agent, officer, consultant, director,
        shareholder, partner, joint venturer, investor or otherwise, in the
        Company Business; provided, however, that the foregoing shall not
        prohibit the ownership by Parent of an equity interest in Company or
        other equity securities of a public company in an amount not to exceed
        2% of the issued and outstanding shares of such company. For purposes of
        this Section 4.10(a), the "Company Business" means the business
        activities described on Exhibit F-2 hereto.

                (ii) Parent acknowledges that the agreements and covenants
        contained in this Section 4.10(a) are essential to protect the value of
        the ROI Assets being conveyed to Company. Parent agrees that a monetary
        remedy for a breach of the agreements set forth


                                      -15-
<PAGE>   19

        in this Section 4.10(a) will be inadequate and impracticable and further
        agree that such a breach would cause Company irreparable harm, and that
        Company shall be entitled to temporary and permanent injunctive relief
        without the necessity of proving actual damages. In the event of such a
        breach, Parent agrees that Company shall be entitled to such injunctive
        relief, including temporary restraining orders, preliminary injunctions
        and permanent injunctions as a court of competent jurisdiction shall
        determine.

                (iii) If any provision of this Section 4.10(a) is invalid in
        part, it shall be curtailed, as to time, location or scope, to the
        minimum extent required for its validity under the laws of the United
        States and shall be binding and enforceable with respect to Parent as so
        curtailed.

                (iv) Parent acknowledges that the Company Business is or may be
        conducted throughout the United States and that its clients are or may
        be located throughout the United States and that a business competitive
        with Company may be carried on anywhere within these areas as a result
        of the unique use of Internet, telephonic, technologic and other
        advanced communications techniques. Parent recognizes and acknowledges
        that the restrictions and limitations set forth in this Agreement are
        legitimate and fair in light Parent's access to confidential information
        relating to Company, Parent's substantial contacts with clients of
        Company and Company's need to market its services and products.

        (b) Covenant of Company.

                (i) Company agrees that for the Restricted Period, Company shall
        not anywhere in North America participate or engage, directly or
        indirectly, for itself or on behalf of or in conjunction with any
        Person, whether as an employee, agent, officer, consultant, director,
        shareholder, partner, joint venturer, investor or otherwise, in the
        Parent Business; provided, however, that the foregoing shall not
        prohibit the ownership by Company of the Shares or other equity
        securities of a public company in an amount not to exceed 2% of the
        issued and outstanding shares of such company. For purposes of this
        Section 4.10(b), the "Parent Business" means professional services,
        consulting, installation, training and education in the following areas
        of the healthcare industry: financial and clinical decision support;
        coding and grouping; abstracting; compliance; accounts receivable and
        cash management; managed care payment review; capitation audits, charge
        data master review; nurse staffing/acuity/resource management;
        electronic data interchange (EDI); business office interim department
        management and outsourcing.

                (ii) Company acknowledges that the agreements and covenants
        contained in this Section 4.10(b) are essential to protect the value of
        the assets of Parent from and after the Closing. Company agrees that a
        monetary remedy for a breach of the agreements set forth in this Section
        4.10(b) will be inadequate and impracticable and further agree that such
        a breach would cause Parent irreparable harm, and that Parent shall be
        entitled to temporary and permanent injunctive relief without the
        necessity of proving actual damages. In the event of such a breach,
        Company agrees that Parent shall be entitled to


                                      -16-
<PAGE>   20

        such injunctive relief, including temporary restraining orders,
        preliminary injunctions and permanent injunctions as a court of
        competent jurisdiction shall determine.

                (iii) If any provision of this Section 4.10(b) is invalid in
        part, it shall be curtailed, as to time, location or scope, to the
        minimum extent required for its validity under the laws of the United
        States and shall be binding and enforceable with respect to Company as
        so curtailed.

                (iv) Company acknowledges that the Parent Business is or may be
        conducted throughout the United States and that its clients are or may
        be located throughout the United States and that a business competitive
        with Parent may be carried on anywhere within these areas as a result of
        the unique use of Internet, telephonic, technologic and other advanced
        communications techniques. Company recognizes and acknowledges that the
        restrictions and limitations set forth in this Agreement are legitimate
        and fair in light Company's access to confidential information relating
        to Parent, Company's substantial contacts with clients of Parent and
        Parent's need to market its services and products.

                                    ARTICLE V

directors, officers and employees (the "Company Indemnitees"), harmless if any

liability, loss, cost, expense (including all reasonable attorneys' fees
incurred by the Company Indemnitees in any action or proceeding between Parent
and the Company Indemnitees or between the Company Indemnitees and any third
party or otherwise), deficiency, interest, penalty, impositions, assessments or
fines (collectively, "Company Losses") arising out of or resulting from, or

one or more of the following:

                (a) any failure of Parent duly to perform or observe any term
        provision, covenant, agreement contained herein on the part of Parent be

                (b) any claim or cause of action by any party against any

<PAGE>   21

                (c) any claims brought by Health+Cast or any other third party
        in connection with any failure of Parent to assign to Company, or to
        obtain consent from Health+Cast as to the assignment to Company of, as
        of the date hereof, (i) the Non-Exclusive Reseller Agreement by and
        between Parent and Health+Cast, dated September 29, 1998 or (ii) the
        Non-Exclusive License Agreement by and between Parent and Health+Cast,
        dated March 31, 1999; or

                (d) any withdrawal liability (imposed under Section 4201 of the
        Employee Retirement Income Security Act of 1974, as amended ("ERISA"))
        in connection with the transactions contemplated by this Agreement.

        Section 5.3 Indemnification by Company

        Notwithstanding the Closing or the delivery of the ROI Assets, Company
shall indemnify and agree to fully defend, save and hold Parent and its
Affiliates, directors, officers and employees (the "Parent Indemnitees"),
harmless if any Parent Indemnitee shall at any time or from time to time suffer
any damage, liability, loss, cost, expense (including all reasonable attorneys'
fees incurred by the Parent Indemnitees in any action or proceeding between
Company and the Parent Indemnitees or between the Parent Indemnitees and any
third party or otherwise), deficiency, interest, penalty, impositions,
assessments or fines (collectively, "Parent Losses") arising out of or resulting
from, or shall pay or become obligated to pay any sum on account of, any and all
Company Events of Breach. As used herein, "Company Events of Breach" shall be
construed to be and mean any one or more of the following:

                (a) any failure of Company duly to perform or observe any term,
        provision, covenant or agreement contained herein on the part of Company
        to be performed or observed after the Closing Date; or

                (b) any claim or cause of action by any party against any Parent
        Indemnitee with respect to the ROI Assets or Assumed Liabilities.

        Section 5.4 Procedures for Indemnification

        If a party entitled to indemnification pursuant to this Article V (an
"Indemnified Party") becomes aware of any liability, loss, damage, claim, cost
or expense with respect to which a claim for indemnification may be asserted
pursuant to this Article V, or if any claim is made by a third Person or any
suit, action, investigation, claim or proceeding (a "Proceeding") commenced for
which the Indemnified Party shall seek indemnity from the Indemnifying Party,
the Indemnified Party shall, with reasonable promptness, give to such
Indemnifying Party written notice of such Proceeding and request the
Indemnifying Party to defend the same, provided, however, that the failure of an
Indemnified Party to deliver such written notice with reasonable promptness
shall not be deemed to bar or otherwise limit the rights of the Indemnified
Party hereunder unless such failure materially prejudices the rights or defenses
of the Indemnifying Party. The Indemnifying Party agrees to defend such claim,
action or proceeding at its own expense, and shall give written notice to the
Indemnified Party of the commencement of such defense with reasonable promptness
after the giving of the written notice of the claim by the


                                      -18-
<PAGE>   22

Indemnified Party. The Indemnified Party shall have the right, but not the
obligation, to participate at its own expense with the Indemnifying Party in
such defense (subject to the right of the Indemnifying Party to control such
defense), but shall not be entitled in any way to release, waive, settle, modify
or pay such claim, action or proceeding without the written consent of the
Indemnifying Party, if the Indemnifying Party has assumed such defense. The
Indemnified Party shall, in any case, fully cooperate with and assist the
Indemnifying Party to the extent reasonably possible. If the Indemnifying Party
fails to timely defend, contest or otherwise protect against such Proceeding,
the Indemnified Party shall have the full right to defend against such claim,
action or proceeding in such manner as it may deem appropriate, including,
without limitation, the right to make any compromise or settlement thereof
(subject to the consent of the Indemnifying Party, which consent shall not be
unreasonably withheld), and the Indemnified Party shall be entitled to recover
the entire cost thereof from the Indemnifying Party, including, without
limitation, reasonable attorneys' fees, disbursements and amounts paid as the
result of such Proceeding, and the Indemnifying Party shall be bound by any
determination made in such Proceeding or (subject to the consent of the
Indemnifying Party, which consent shall not be unreasonably withheld) any
compromise or settlement effected by the Indemnified Party. In the event the
Indemnifying Party shall assume the defense, no compromise or settlement of such
claims may be effected by the Indemnifying Party without the Indemnified Party's
consent (which consent shall not be unreasonably withheld, provided, however
that the Indemnified Party may withhold such consent at its discretion if, in
its judgment, such compromise or settlement would have an adverse impact on the
future operations of the Indemnified Party).

        Section 5.5 Arbitration

        (a) Company and Parent agree that the arbitration procedure set forth
below shall be the sole and exclusive method for resolving and remedying claims
for money damages arising out of the provisions of this Agreement (the
"Disputes"). Nothing in this Section 5.5 shall prohibit either Company or Parent
from instituting litigation to enforce any Final Determination (as defined
below). The parties hereby agree and acknowledge that, except as otherwise
provided in this Section 5.5 or in the Commercial Arbitration Rules of the
American Arbitration Association as in effect from time to time, the arbitration
procedures and any Final Determination hereunder shall be governed by, and shall
be enforced pursuant to applicable Delaware law.

        (b) In the event that either Company or Parent asserts that there exists
a Dispute, such party shall deliver a written notice to each other party
involved therein specifying the nature of the asserted Dispute and requesting a
meeting to attempt to resolve the same. If no such resolution is reached within
ten Business Days after such delivery of such notice, the party delivering such
notice of Dispute (the "Disputing Person") may, within 45 Business Days after
delivery of such notice, commence arbitration hereunder by delivering to each
other party involved therein a notice of arbitration (a "Notice of
Arbitration"). Such Notice of Arbitration shall specify the matters as to which
arbitration is sought, the nature of any Dispute, the claims of each party to
the arbitration and shall specify the amount and nature of any damages, if any,
sought to be recovered as a result of any alleged claim, and any other matters
required by the


                                      -19-
<PAGE>   23

Commercial Arbitration Rules of the American Arbitration Association in effect
from time to time to be included therein, if any.

        (c) Company and Parent each shall select one arbitrator expert in the
subject matter of the Dispute (the arbitrators so selected shall be referred to
herein as the "Company's Arbitrator" and the "Parent's Arbitrator,"
respectively). In the event that either party fails to select an arbitrator as
set forth herein within 20 calendar days from the delivery of a Notice of
Arbitration, then the matter shall be resolved by the arbitrator selected by the
other party. The Parent's Arbitrator and Company's Arbitrator shall select a
third independent, neutral arbitrator expert in the subject matter of the
dispute, and the three arbitrators so selected shall resolve the matter
according to the procedures set forth in this Section 5.5. If the Parent's
Arbitrator and Company's Arbitrator are unable to agree on a third arbitrator
within 20 calendar days after their selection, the Parent's Arbitrator and
Company's Arbitrator shall each prepare a list of three independent arbitrators.
The Parent's Arbitrator and Company's Arbitrator shall each have the opportunity
to designate as objectionable and eliminate one arbitrator from the other
arbitrator's list within seven calendar days after submission thereof, and the
third arbitrator shall then be selected by lot from the arbitrators remaining on
the lists submitted by the Parent's Arbitrator and Company's Arbitrator.

        (d) The arbitrator(s) selected pursuant to Section 5.5(c) above will
determine the allocation of the costs and expenses of arbitration based upon the
percentage which the portion of the contested amount not awarded to each party
bears to the amount actually contested by such party. For example, if Company
submits a claim for $1,000 and if Parent contests only $500 of the amount
claimed by Company, and if the arbitrator(s) ultimately resolves the dispute by
awarding Company $300 of the $500 contested, then the costs and expenses of
arbitration will be allocated 60% (that is, 300 divided by 500) to Parent and
40% (that is, 200 divided by 500) to Company.

        (e) The arbitration shall be conducted in the State of Delaware under
the Commercial Arbitration Rules of the American Arbitration Association as in
effect from time to time, except as modified by the agreement of all of the
parties to this Agreement. The arbitrator(s) shall so conduct the arbitration
that a final result, determination, finding, judgment and/or award (the "Final
Determination") is made or rendered as soon as practicable, but in no event
later than 90 Business Days after the delivery of the Notice of Arbitration nor
later than 10 calendar days following completion of the arbitration. The Final
Determination must be agreed upon and signed by the sole arbitrator or by at
least two of the three arbitrators (as the case may be). The Final Determination
shall be final and binding on all parties and there shall be no appeal from or
reexamination of the Final Determination, except for fraud, perjury, evident
partiality or misconduct by an arbitrator prejudicing the rights of any party
and to correct manifest clerical errors.

        (f) Company and Parent may enforce any Final Determination in any state
or federal court located in the State of Delaware. For the purpose of any action
or proceeding instituted with respect to any Final Determination, each party
hereto hereby irrevocably submits to the jurisdiction of such courts,
irrevocably consents to the service of process by registered mail or personal
service and hereby irrevocably waives, to the fullest extent permitted by law,
any


                                      -20-
<PAGE>   24

objection which it may have or hereafter have as to personal jurisdiction, the
laying of the venue of any such action or proceeding brought in any such court
and any claim that any such action or proceeding brought in any court has been
brought in an inconvenient forum.

        (g) Any party required to make a payment pursuant to this Section 55
shall pay the party entitled to receive such payment within ten calendar days of
the delivery of the Final Determination to such responsible party. If any party
shall fail to pay the amount of any damages, if any, assessed against it within
such ten calendar day period, the unpaid amount shall bear interest from the
date of such delivery at the lesser of (i) the prime rate of interest published
by the Board of Governors of the Federal Reserve System as the "Bank Prime Loan"
rate, in effect from time to time (which rate shall be adjusted on the effective
date of each change in such prime rate) plus 2.00% and (ii) the maximum rate
permitted by applicable usury laws. Interest on any such unpaid amount shall be
compounded semi-annually, computed on the basis of a 360-day year consisting of
twelve 30-day months and shall be payable on demand. In addition, such party
shall promptly reimburse the other party for any and all costs and expenses of
any nature or kind whatsoever (including but not limited to all attorney's fees)
incurred in seeking to collect such damages or to enforce any Final
Determination.

        Section 5.6 No Consequential Damages; Exclusive Remedy

        No party hereto shall have any liability for loss of profit or
consequential damages with respect to this Agreement or the transactions
contemplated hereby. Absent fraud, the indemnification provided by this Article
V shall be the sole and exclusive remedy available to the parties hereto with
respect to any claim or cause of action based upon, relating to or arising out
of this Agreement or otherwise in respect of the transactions contemplated
hereby, whether such claim or cause of action arises out of any contract, tort
or otherwise.

        Section 5.7 Tax Benefit

        Notwithstanding the above, if losses, damages, claims, costs or expenses
are incurred by any party which are indemnifiable under this Article V, and if
indemnification of any losses, damages, claims, costs or expenses would result
in a deduction, credit or other tax benefit to the Indemnified Party under
federal or state laws, the amount indemnifiable under this Article V shall be
reduced to reflect such tax benefit.

        Section 5.8 Mitigation

        Each Indemnified Party shall use reasonable efforts to mitigate any
liabilities and damages for which it may claim indemnification under this
Article V. To the extent that the operations of Company at any time that Company
is not under the control of Parent contribute to or aggravate any liabilities or
damages as to which indemnification is available under Section 5.2, Parent's
indemnification obligation will be reduced by such contribution or aggravation.
