To Our Stockholders:

     You are cordially invited to attend the annual meeting of stockholders of
Neoforma.com, Inc. to be held at our headquarters located at 3061 Zanker Road,
San Jose, California 95134, on July 26, 2000 at 8:30 a.m., Pacific Time.

     The matters expected to be acted upon at the meeting include the following
proposals, which are described in detail in the following Notice of the 2000
Annual Meeting of Stockholders and the accompanying proxy statement:

     1. The election of Messrs. David L. Douglass, Wayne D. McVicker and
        Madhavan Rangaswami as the three Class I directors, each to serve a
        three-year term or until his successor has been elected and qualified or
        until his earlier resignation or removal. If our stockholders approve
        the proposed issuance of our common stock and warrants to purchase our
        common stock to VHA Inc., or VHA, and University HealthSystem
        Consortium, or UHC, it is expected that Messrs. McVicker and Rangaswami
        will then resign from our board, and the remaining members of our board
        would be expected to appoint the two candidates designated by VHA, Mr.
        Curt Nonomaque, the Executive Vice President and Chief Financial Officer
        of VHA, and Mr. Mark McKenna, the President of Novation, LLC, or
        Novation, as Class I directors.

     2. The approval of the issuance of shares of our common stock and warrants
        to purchase our common stock to VHA and UHC, the owners of Novation, in
        connection with an amended and restated outsourcing and operating
        agreement with Novation and its owners. If our stockholders approve the
        proposed issuance of our stock and warrants to purchase our common stock
        to VHA and UHC, immediately after such issuance, VHA will own
        approximately 37% of our common stock, UHC will own approximately 9% of
        our common stock and all other stockholders will own, in the aggregate,
        approximately 55% of our common stock. Assuming that (1) all options and
        warrants outstanding on June 23, 2000, including the warrants to be
        issued to VHA and UHC, are fully exercised, (2) none of the shares of
        our common stock issued to VHA and UHC are forfeited, (3) VHA and UHC
        achieve all performance-based milestones in their respective warrants
        and (4) VHA and UHC do not distribute their shares to any of their
        members or patrons or otherwise, then VHA would own approximately 44% of
        our common stock, UHC would own approximately 11% of our common stock
        and all other stockholders would own, in the aggregate, approximately
        45% of our common stock.

     3. The approval of an amendment to our certificate of incorporation to
        increase the authorized number of shares of common stock to 300,000,000.

     4. The ratification of the selection of Arthur Andersen LLP as our
        independent auditors for the year ending December 31, 2000.

     5. The transaction of any other business that may properly come before our
        annual meeting of stockholders or any adjournment or postponement of the
        meeting.

     After careful consideration, our board of directors has unanimously
approved the amended and restated outsourcing and operating agreement with
Novation and its owners, the common stock and warrant agreements with the owners
of Novation and has determined that the issuance of shares of common stock and
warrants in connection with the strategic relationship with Novation and its
owners is fair to and in the best interests of us and our stockholders. Our
board of directors unanimously recommends that you approve this item, as well as
the other matters to be voted upon at the stockholders meeting.

     It is important that you use this opportunity to take part in our affairs
by voting on the business to come before this meeting. WHETHER OR NOT YOU EXPECT
TO ATTEND THE MEETING, PLEASE COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE
ACCOMPANYING PROXY IN THE ENCLOSED POSTAGE-PAID ENVELOPE SO THAT YOUR SHARES MAY
BE REPRESENTED AT THE MEETING. YOUR VOTE IS VERY IMPORTANT. Returning the proxy

in person.

                                      Sincerely,

                                      /s/ Robert J. Zollars

meeting. As of the record date, there were approximately 69,017,590 outstanding
shares of our common stock, held by approximately 350 holders of record,
although the total number of beneficial holders is greater than that represented

matter submitted for a vote at our annual stockholders meeting.


QUORUM REQUIREMENTS AND VOTE REQUIRED

     The representation, in person or by properly executed proxy, of the holders
of a majority of all of the shares of stock entitled to vote at our annual
meeting of stockholders is necessary to constitute a quorum at the meeting or
any adjournment of the meeting.

     The approval and adoption of each of the proposals described above will
require the affirmative vote of our stockholders as follows:

- Election of Class I directors                 - Each Class I director will be elected by the
                                                  votes of a plurality of the shares of our
                                                  common stock present in person or represented
                                                  by proxy at the meeting and entitled to vote
                                                  at the meeting

- The issuance of shares of our common stock    - Majority of the shares of our common stock
  and warrants to purchase our common stock       present in person or represented by proxy at
  to the owners of Novation in connection         the meeting and entitled to vote at the
  with the amended and restated outsourcing       meeting
  and operating agreement

- Amendment of our certificate of               - Majority of the outstanding shares of our
  incorporation to increase the authorized        common stock entitled to vote at the meeting
  number of shares of common stock to
  300,000,000

- Ratification of Arthur Andersen LLP as our    - Majority of the shares of our common stock
  independent auditors                            present in person or represented by proxy at
                                                  the meeting and entitled to vote at the
                                                  meeting
</TABLE>

     Shares of our common stock, represented in person or by proxy, will be
counted for the purpose of determining whether a quorum is present at our annual
meeting of stockholders. Shares that abstain from voting as to a particular
matter will be treated as shares that are present and entitled to vote at our
annual meeting of stockholders for purposes of determining whether a quorum
exists. Abstentions will have the same effect as votes against the indicated
proposals. If a broker or nominee holding stock in "street name" indicates on a
proxy that it does not have discretionary authority to vote as to a particular
matter, which we call a broker non-vote, those shares will be treated as present
and entitled to vote at our annual meeting of stockholders for purposes of
determining whether a quorum exists. With respect to Proposal No. 3 relating to
the amendment of our certificate of incorporation, broker non-votes will have
the same effect as a vote against this proposal. For each of the other
proposals, broker non-votes will have no effect.

     Several of our stockholders, including each of our directors or entities
affiliated with them, have entered into voting agreements with VHA and UHC under
which they have agreed to vote a portion of the shares owned by them,
constituting, in the aggregate, approximately 25% of our outstanding common
stock, in favor of the issuance of our common stock and warrants to VHA and UHC.

SOLICITATION OF PROXIES

     This document is being furnished to our stockholders in connection with the
solicitation of proxies by and on behalf of our board for use at our annual
meeting of stockholders, and is accompanied by a form of proxy.

                                 PROPOSAL NO. 1

                             ELECTION OF DIRECTORS

     Our bylaws currently provide for a board of directors consisting of seven
members. Our certificate of incorporation and bylaws provide that the board of
directors are divided into three classes, each serving staggered three-year
terms: Class I, Class II and Class III. One class of directors is elected by our
stockholders at each annual meeting, with each director to serve a three-year
term or until that director's successor is duly elected and qualified.

     The Class I directors are currently Messrs. David L. Douglass, Wayne D.
McVicker and Madhavan Rangaswami. These directors are standing for re-election
at this meeting. Under the amended and restated common stock and warrant
agreement with VHA, which is described under Proposal No. 2, if the issuance of
shares of our common stock and warrants to purchase our common stock to the
owners of Novation is approved, VHA will have the right to designate two Class I
directors following this annual meeting. If the issuance of shares of our common
stock and warrants to purchase our common stock to the owners of Novation is
approved, it is expected that Messrs. McVicker and Rangaswami will resign from
our board subsequent to their re-election as Class I directors. The remaining
members of our board would then be expected to appoint the two candidates
designated by VHA, Mr. Curt Nonomaque, the Executive Vice President and Chief
Financial Officer of VHA, and Mr. Mark McKenna, President of Novation, as Class
I directors. Further, under the amended and restated common stock and warrant
agreement with VHA, for so long as VHA holds 10% or more of our common stock,
including the shares issuable upon exercise of its warrant, VHA will have the
right to designate one member of our board of directors. Additionally, under
this agreement, for so long as VHA holds 20% or more of our common stock,
including the shares issuable upon exercise of its warrant, VHA will have the
right to designate two members of our board of directors.

     If any nominee for any reason is unable to serve, or for good cause will
not serve, as a director, the proxies may be voted for a substitute nominee as
the proxy holder may determine. We are not aware of any nominee who will be
unable to serve, or for good cause will not serve, as a director.

BOARD MEETINGS AND BOARD COMMITTEES

acted by written consent three times during 1999. No director attended fewer
than 75% of the aggregate of the total number of meetings of the board held
during the period for which that director was a director and the total number of
meetings held by all committees of the board on which that director served
during the period that the director served.

  Board Committees

     Our board of directors has an audit committee and a compensation committee.

     Audit Committee. The audit committee was created during the fourth quarter
of fiscal 1999 and consists of Messrs. Filipowski, Garnett and Rangaswami. The
audit committee met two times during 1999. The audit committee:

     - reviews our financial statements and accounting practices;

     - makes recommendations to our board of directors regarding the selection
       of independent public accountants; and

     - reviews the results and scope of the audit and other services provided by
       our independent public accountants.

     Compensation Committee. The compensation committee was created during the
fourth quarter of fiscal 1999 and consists of Messrs. Douglass, Filipowski and
Helppie. The compensation committee did not meet in 1999. The compensation
committee:

     - reviews and recommends to our board of directors the compensation and
       benefits of all of our officers, directors and consultants; and

     - reviews general policy relating to compensation and benefits.

DIRECTOR COMPENSATION

     Our directors do not receive cash compensation for their services as
directors but are reimbursed for their reasonable and necessary expenses for
attending board and board committee meetings.

     Each eligible director who is not our employee and who is or becomes a
member of our board will be automatically granted an option to purchase 100,000
shares of our common stock under our 1999 Equity Incentive Plan, unless that
director has previously received an option grant. Immediately following each
annual meeting of stockholders, each eligible director will automatically be
granted an option to purchase 25,000 shares of common stock under our 1999
Equity Incentive Plan, provided that the director is a member of our board on
that date and has served continuously as a member of our board for a period of
at least one

                                        6
<PAGE>   11

year since the date of the director's initial grant. All options will have an
exercise price equal to the fair market value of our common stock on the date of
grant. The options will have ten-year terms and will terminate three months
following the date that the director ceases to be one of our directors or
consultants or 12 months after any termination due to death or disability.
Options granted under the plan will generally vest over four years. Any unvested
shares subject to these options will become immediately vested and exercisable
upon a transaction which results in a change in control of Neoforma.

     Upon joining our board of directors in October 1999, we granted each of
Richard D. Helppie and Andrew J. Filipowski an option to purchase 150,000 shares
of our common stock at an exercise price of $4.00 per share. The shares
underlying the options vest over three years, with one-third of the shares
vesting at the end of the first anniversary of the date of grant and an
additional one thirty-sixth vesting each month thereafter for so long as they
serve as one of our directors.

                                 PROPOSAL NO. 2

             APPROVAL OF ISSUANCE OF SHARES OF OUR COMMON STOCK AND
        WARRANTS TO PURCHASE OUR COMMON STOCK TO THE OWNERS OF NOVATION

DESCRIPTION OF NOVATION, VHA, UHC AND HPPI

     Novation is a group purchasing organization that pools its purchasing power
to provide better pricing for medical products, services and equipment for the
more than 6,500 community-owned hospitals, academic medical centers and other
healthcare providers that are patrons, members or affiliates of VHA, UHC, and
Healthcare Purchasing Partners International, LLC, or HPPI. In 1999, these
organizations purchased more than $14.0 billion of products and services through
Novation-negotiated agreements. Based on this volume of purchases, we believe
that Novation is the world's largest contracting agent for the purchase of
healthcare supplies.

     Novation was formed in 1998 through the combination of the group purchasing
programs of VHA and UHC. It is owned by VHA and UHC, with VHA owning
approximately 80% of the membership interests of Novation as of January 1, 2000.
Under its operating agreement with VHA and UHC, Novation acts as the exclusive
negotiating agent to provide supply chain management services to VHA and UHC.
Novation has no direct contractual arrangement with the patrons or members of
VHA and UHC. As a contracting agent for VHA, UHC and, indirectly, for their
patrons and members, Novation develops and enters into agreements for healthcare
products and services and provides these same parties with related services. The
purchasing programs and services currently offered by Novation to VHA, UHC and
their patrons and members include traditional catalog-based programs, as well as
Internet-based tools such as an online catalog, web-based cross-referencing and
web tools for product standardization. In addition to serving VHA and UHC
patrons and members, Novation makes its agreements accessible to 4,500
healthcare organizations and their related physicians that purchase supplies
through HPPI, a company also owned by VHA and UHC. In addition, Novation also
has relationships with a wide range of health care suppliers.

     VHA is a nationwide network of more than 1,900 leading community-owned
healthcare organizations and their affiliated physicians. The VHA alliance
comprises approximately 26% of the nation's community hospitals, including many
of the nation's largest medical institutions. UHC is an alliance of 82 academic
medical centers and 77 associate members. UHC represents approximately 70% of
the academic medical centers in the United States. Both UHC and VHA act as group
purchasing organizations. HPPI is a group purchasing organization that develops
and delivers supply chain management agreements, programs and services on behalf
of healthcare organizations that are not members of VHA or UHC. At present, VHA
owns approximately 75% of the membership interests of HPPI, and UHC owns the
remaining interests.

BACKGROUND OF THE NOVATION TRANSACTIONS

     In February 2000, we had preliminary discussions with Eclipsys Corporation,
HEALTHvision, Inc., or HEALTHvision, and VHA regarding a relationship among them
in conjunction with a commercial arrangement between us and Novation. In March
2000, these parties met to negotiate the terms of these potential transactions
which led to discussions regarding a merger of us, Eclipsys and HEALTHvision,
and a commercial arrangement with Novation. On March 30, 2000, we entered into
merger agreements with Eclipsys and HEALTHvision, an outsourcing and operating
agreement with Novation, VHA, UHC and HPPI, and common stock and warrant
agreements with VHA and UHC.

     The stock market response to the announcement of the mergers was
unfavorable and, subsequently, the parties entered into discussions to
restructure the transactions. On May 24, 2000, all of the parties to the
original transactions entered into an agreement terminating both the Eclipsys
merger and the HEALTHvision merger. We also entered into a commercial
arrangement with HEALTHvision. The outsourcing and operating agreement with
Novation, VHA, UHC and HPPI was amended and restated, as were the common stock
and warrant agreements with VHA and UHC, respectively. In conjunction with the
amended and restated common stock and warrant agreements, VHA and UHC agreed to
tie the vesting of their respective warrants to increased performance criteria.

REASONS FOR THE NOVATION TRANSACTIONS

     Our board of directors approved the Novation transactions including the
issuance of common stock and warrants to purchase shares of our common stock to
Novation's owners, VHA and UHC, in exchange for VHA and UHC's obligations under
the amended and restated outsourcing and operating agreement and determined that
these transactions are each fair to, and in the best interests of, our
stockholders. In making this decision, our board of directors considered a
number of factors, including:

     - the access that our relationship with Novation would provide to the
       healthcare organizations that are patrons or members of VHA, UHC and HPPI
       and to the physicians that are affiliated with these healthcare
       organizations;

     - the ability that Novation's relationships with suppliers and distributors
       would provide us to expand the breadth and depth of products and services
       we offer through our online marketplace;

     - the opportunity provided by the transactions with Novation, VHA, UHC and
       HPPI to expand the number of suppliers using our online marketplace by
       using Novation as our contracting agent with suppliers and by leveraging
       Novation's supplier sales force and its experience and relationships with
       suppliers;

     - the opportunity provided by the Novation transactions to cross-sell our
       products and services to the patrons and member healthcare organizations
       of VHA, UHC and HPPI and the suppliers and distributors with which
       Novation has relationships;

     - the ability that the Novation relationship will give to us to enable us
       to compete more effectively in our markets;

     - the impact of the Novation relationship and the transactions on our
       business model and financial position and the potential acceleration of
       our business model and our ability to achieve profitability;

     - alternative business strategies to the Novation transactions;

     - compatibility of our management and businesses with that of Novation,
       VHA, UHC and HPPI;

     - the provisions of the amended and restated common stock and warrant
       agreements and the amended and restated outsourcing and operating
       agreement and the other transaction documents; and

     - the detailed financial analysis with respect to us and the Novation
       transactions presented by our financial advisor and their opinion as to
       the fairness, from a financial point of view, to our stockholders of the
       Novation transactions.

     In addition to the foregoing factors, our board of directors also
considered a number of risks and potentially negative factors in the
deliberations concerning the Novation transactions, including:

     - the significant challenges in bringing the large number of healthcare
       organizations that are patrons and members of VHA, UHC and HPPI to our
       online marketplace and integrating their systems into our e-commerce
       system;

     - the ownership dilution to our stockholders that would occur as a result
       of the stock and warrant issuances to VHA and UHC;

     - the risk that the financial benefits of the relationships with Novation,
       VHA, UHC and HPPI will not be realized, whether due to generation of
       lower than expected revenue or purchase volumes or otherwise;

     - the risk of diverting management and technical resources from operating
       the day-to-day business and from focusing on our existing services;

     - the risk that the Novation relationship could make it more difficult to
       do business with other group purchasing organizations or otherwise limit
       our growth plans;

                                        9
<PAGE>   14

     - the significant challenges in meeting the requirements of the amended and
       restated outsourcing and operating agreement and the risk of termination
       or damages if such requirements are not met; and

     - the possibility that the other perceived benefits of the relationships
       with Novation, VHA, UHC and HPPI will not be realized.

     Our board of directors did not find it practical to quantify, rank or
otherwise assign relative or specific weights to the factors considered. In
addition, our board did not reach any specific conclusion with respect to each
of the factors considered or any aspect of any particular factor, but, rather,
conducted an overall analysis of the factors described above, including
discussions with our management and legal, financial and accounting advisors. In
considering the factors described above, individual members of our board may
have given different weight to different factors. Our board considered all these
factors as a whole and believed the factors supported its determination to
approve the Novation transactions. After taking into consideration all of the
factors set forth above, our board concluded that the Novation transactions,
including the issuance of 57,546,680 shares of our common stock to the owners of
Novation and the issuance to the owners of Novation of warrants to purchase an
additional 38,364,456 shares of our common stock, are fair to, and in the best
interests, of us and our stockholders and that we should proceed with these
transactions.

     OUR BOARD HAS DETERMINED THAT THE NOVATION TRANSACTIONS, INCLUDING THE
ISSUANCE OF 57,546,680 SHARES OF OUR COMMON STOCK TO VHA AND UHC, THE OWNERS OF
NOVATION, AT THE CLOSING OF THE TRANSACTIONS AND THE ISSUANCE TO THE OWNERS OF
NOVATION OF WARRANTS TO PURCHASE ADDITIONAL 38,364,456 SHARES OF OUR COMMON
STOCK, TO BE FAIR TO AND IN THE BEST INTERESTS OF OUR STOCKHOLDERS.

OPINION OF NEOFORMA'S FINANCIAL ADVISOR

     We retained Merrill Lynch & Co., or Merrill Lynch, as our financial advisor
for the Novation transactions based upon Merrill Lynch's experience and
expertise and familiarity with Neoforma gained through acting as the managing
underwriter for our January 2000 initial public offering. Merrill Lynch is an
internationally recognized investment banking business, regularly engaged in the
valuation of businesses and securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes.

     On May 20, 2000, Merrill Lynch delivered to our board of directors its oral
opinion, which it subsequently confirmed in writing by delivery of an opinion
dated May 24, 2000, to the effect that, as of the date of the opinion, and based
upon and subject to the factors and assumptions set forth in the opinion, the
Novation transactions were fair from a financial point of view to us.

     The full text of Merrill Lynch's fairness opinion, which sets forth the
assumptions made, matters considered and qualifications and limitations on the
review undertaken by Merrill Lynch, is attached as Annex A. The summary of
Merrill Lynch's fairness opinion set forth in this document is qualified in its
entirety by reference to the full text of Merrill Lynch's fairness opinion. You
are urged to read this opinion carefully and in its entirety.

     The Merrill Lynch opinion speaks only as of its date, and Merrill Lynch is
under no obligation to confirm its opinion as of any later date. Our board of
directors may not necessarily request that Merrill Lynch confirm its opinion as
of any later date.

     In reading the following discussion of the Merrill Lynch fairness opinion,
you should be aware that the opinion:

     - was provided to our board of directors for its information and is
       directed only to the fairness, from a financial point of view, of the
       Novation transactions to us;

     - did not constitute a recommendation to our board of directors in
       connection with its consideration of the Novation transactions;

                                       10
<PAGE>   15

     - did not address the merits of the underlying decision by us to engage in
       the Novation transactions or the price or range of prices at which shares
       of our common stock may trade subsequent to the announcement or
       consummation of the Novation transactions; and

     - did not constitute a recommendation to any holder of our common stock as
       to how such stockholder should vote on the Novation transactions or any
       related matter.

     In arriving at its opinion, Merrill Lynch, among other things:

     - reviewed certain publicly available business and financial information
       relating to Novation and us that Merrill Lynch deemed to be relevant;

     - reviewed certain information, including financial forecasts, relating to
       our business, earnings, revenues, cash flow, assets, liabilities and
       prospects furnished to Merrill Lynch by us, as well as projected cash
       flows for the Novation outsourcing arrangement furnished to Merrill Lynch
       by us and Novation;

     - conducted discussions with members of our and Novation's senior
       management concerning the matters described in the above two bullet
       points, as well as our business and prospects in the case of our
       management, and the business and prospects of the Novation outsourcing
       arrangement in the case of Novation management, before and after giving
       effect to the Novation transactions;

     - reviewed the trading multiples for our common stock and compared them
       with those of certain publicly traded companies that Merrill Lynch deemed
       to be relevant;

     - participated in certain discussions and negotiations among our and
       Novation's representatives and our respective financial and legal
       advisors;

     - reviewed the potential pro forma impact of the Novation transactions from
       a financial point of view;

     - reviewed the Amended and Restated Outsourcing and Operating Agreement,
       the Amended and Restated VHA Common Stock and Warrant Agreement and the
       Amended and Restated UHC Common Stock and Warrant Agreement; and

     - reviewed such other financial studies and analyses and took into account
       such other matters as Merrill Lynch deemed necessary, including Merrill
       Lynch's assessment of general economic, market and monetary conditions.

     In preparing its opinion, Merrill Lynch assumed and relied on the accuracy
and completeness of all information supplied or otherwise made available to
Merrill Lynch, discussed with or reviewed by or for Merrill Lynch, or publicly
available, and Merrill Lynch did not assume any responsibility for independently
verifying such information and Merrill Lynch has not undertaken an independent
evaluation or appraisal of any of our assets or liabilities or been furnished
with any such evaluation or appraisal. In addition, Merrill Lynch did not assume
any obligation to conduct any physical inspection of our properties or
facilities. With respect to our financial forecast information furnished to or
discussed with Merrill Lynch by our management, and the financial forecast
information for the Novation outsourcing arrangement furnished to or discussed
with our and Novation's management, Merrill Lynch assumed that they had been
reasonably prepared and reflected the best available estimates and judgment of
such management as to the expected future financial performance of such entity,
as the case may be.

     Merrill Lynch's fairness opinion is necessarily based on market, economic
and other conditions as they existed and could be evaluated on, and on the
information made available to Merrill Lynch as of, the date of the opinion.
Merrill Lynch assumed that in the course of obtaining the necessary regulatory
or other consents or approvals, contractual or otherwise, for the transaction,
no restrictions, including any divestiture requirements or amendments or
modifications, will be imposed that will have a material adverse effect on the
contemplated benefits of the Novation transactions.

     In preparing its opinion to our board of directors, Merrill Lynch performed
financial and comparative analyses, including those described below. The summary
of analyses set forth in this document does not purport to be a complete
description of the analyses underlying Merrill Lynch's fairness opinion or the

                                       11
<PAGE>   16

presentation made by Merrill Lynch to our board of directors. The preparation of
a fairness opinion is a complex analytic process involving various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of those methods to the particular circumstances
and, therefore, such an opinion is not readily susceptible to partial analysis
or summary description. No company, business or transaction used in such
analyses as a comparison is identical to the Novation outsourcing arrangement or
us, or the Novation transactions, nor is an evaluation of the results of such
analyses entirely mathematical; rather it involves complex considerations and
judgments concerning financial and operating characteristics and other factors
that could affect the acquisition, public trading or other values of the
companies, business segments or transactions being analyzed.

     In arriving at its opinion, Merrill Lynch did not attribute any particular
weight to any analysis or factor considered by it, but rather made qualitative
judgments as to the significance and relevance of each analysis and factor.
Accordingly, Merrill Lynch believes that its analyses must be considered as a
whole and that selecting portions of its analyses, without considering all
analyses, would create an incomplete view of the process underlying its opinion.

     In performing its analyses, numerous assumptions were made with respect to
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Merrill
Lynch, Novation or us. The estimates contained in the analyses performed by
Merrill Lynch and the ranges of valuations resulting from any particular
analysis are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable than those
suggested by such analyses. Additionally, estimates of the value of businesses
or securities do not purport to be appraisals or to reflect the prices at which
such businesses or securities might actually be sold. Accordingly, such analyses
and estimates are inherently subject to substantial uncertainty. In addition, as
described above, Merrill Lynch's fairness opinion was among several factors
taken into consideration by our board of directors in making its determination
to approve the Novation transactions. Consequently, the Merrill Lynch analyses
described below should not be viewed as determinative of the decision of our
board of directors or our management with respect to the fairness of the
Novation transactions.

     The following is a summary of the material financial and comparative
analyses performed by Merrill Lynch in arriving at its opinion and presented to
our board of directors. The Merrill Lynch opinion is based upon Merrill Lynch's
consideration of the collective results of all such analyses, together with the
other factors referred to in its opinion letter.

     NOVATION

     Comparable Publicly Traded Companies Analysis.  In order to assess how the
public market values revenue streams from businesses similar to those expected
from the Novation outsourcing arrangement, Merrill Lynch compared the projected
annual revenue from certain publicly-traded comparable businesses to their
current trading values and calculated the multiple of each company's current
diluted market capitalization, defined as the aggregate market value of
outstanding equity securities including options and warrants, as adjusted for
the treasury stock method plus any funded debt, to its estimated 2001 revenue.
The results derived from this analysis are referred to as Revenue Multiples.

     The comparable companies were chosen because they are publicly traded
companies with revenue streams that, for purposes of analysis, may be considered
similar to revenue streams expected to be generated by the Novation outsourcing
arrangement.

     The Revenue Multiples derived from this analysis were reduced by 25%,
reflecting Merrill Lynch's view that, as a standalone private company, the
revenue from the group purchasing organization would be valued by the market at
a lower multiple than those applied to publicly traded companies with existing
operations. The reduced multiples were then applied to the anticipated 2001
revenues of the Novation outsourcing arrangement, as projected by the
managements of Neoforma and Novation, to arrive at a value range for the
arrangement.

                                       12
<PAGE>   17

     Because of the inherent differences in the businesses, operations,
financial conditions and prospects of the Novation outsourcing arrangement and
the selected comparable companies, Merrill Lynch believed that purely
quantitative comparable companies analyses would not be dispositive in the
context of the transaction. Merrill Lynch believed that an appropriate use of
comparable company analyses in this instance involves judgments concerning the
qualitative differences among the financial and operating characteristics of the
selected comparable companies and the relationship contemplated by the Novation
outsourcing arrangement, which judgments are reflected in the Merrill Lynch
opinion.

     Discounted Cash Flow Analysis.  Merrill Lynch performed a discounted cash
flow analysis of the projected after-tax debt-free cash flow from the
relationship contemplated by the Novation outsourcing arrangement, defined as
after-tax debt-free incremental net transaction revenues less incremental costs
associated with those revenues. Merrill Lynch calculated a range of present
values for the relationship contemplated by the Novation outsourcing arrangement
based upon the discounted present value of the sum of the stream of after-tax
debt-free cash flows of the relationship contemplated by the Novation
outsourcing arrangement. The terminal value was calculated by applying an
assumed perpetuity growth rate of 6% to 7% to the 2004 cash flows. Applying a
range of discounts rates, Merrill Lynch calculated implied equity values for the
arrangement ranging from approximately $700 million to $1,650 million.

     NEOFORMA

     Comparable Publicly Traded Companies Analysis.  In order to assess how the
public market values shares of similar publicly traded companies, Merrill Lynch
reviewed and compared revenue information for us to corresponding information
for two healthcare business-to-business e-commerce companies and a group of five
other business-to-business e-commerce companies outside of the healthcare
industry, in each case considered by Merrill Lynch to be reasonably comparable
to us for purposes of this analysis. The two healthcare business-to-business
e-commerce companies were Ventro Corporation and SciQuest.com, Inc. The
non-healthcare business-to-business e-commerce companies considered comparable
to us were:

- Ariba, Inc.
- FreeMarkets, Inc.
- Commerce One, Inc.
- PurchasePro.com, Inc.
- VerticalNet, Inc.

     Merrill Lynch calculated the diluted market capitalization of each of the
comparable companies as a multiple of Wall Street research estimates of 2001
revenues. This analysis indicated that the ratio of diluted market
capitalization to estimated 2001 revenue for the healthcare business-to-business
e-commerce companies ranged from 20x to 28x. The ratio of diluted market
capitalization to estimated 2001 revenue for the five non-healthcare
business-to-business e-commerce companies ranged from 8x to 44x. These ranges
compare to a multiple of 28x for us. Based on a range of multiples, Merrill
Lynch derived a range of value for us of between $580 million to $1,100 million.

     RELATIVE VALUATION ANALYSES

     Ownership Analysis.  Based on the valuation ranges Merrill Lynch derived
for us and the Novation outsourcing arrangement, Merrill Lynch compared the
high, mid and low points of those valuation ranges to derive implied ownership
interests for existing holders of our common stock after giving effect to the
Novation transactions. Those implied ownership interests were:

     These implied ownership interests compare to the 54.9% basic ownership
interest for our existing common stockholders and 45.0% fully diluted ownership.

     Contribution Analysis.  Merrill Lynch compared the ownership interest of
our existing stockholders, after giving effect to the Novation transactions, of
approximately 54.9% basic ownership and 45.0% fully diluted ownership to our
estimated contribution to the aggregate revenue and EBITDA for each of the five
years between 2000 and 2004. The calculations were based, alternatively, on the
projections of management of each entity and on potential Wall Street research
estimates, i.e., projections for each entity as might be discounted by a Wall
Street research analyst. The calculations indicate that under the management and
potential Wall Street research cases, Neoforma and Novation would contribute the
percentages of revenue and EBITDA in each of the five years indicated in the
tables below. Where indicated below, NM means that the percentage was not
material.

     Pro Forma Analysis. Merrill Lynch analyzed certain pro forma effects which
could result from the Novation transactions.

     Merrill Lynch calculated the pro forma impact the Novation transactions
would have on our revenue, EBITDA and equity value per share, based on (1)
projections furnished by or discussed with the managements of Neoforma and
Novation and (2) potential Wall Street research estimates of 2001 revenue for us
and the Novation outsourcing arrangement. The equity value per share analysis
indicated that, at revenue multiples ranging from 20x to 60x and based upon
potential Wall Street research estimates, the transaction would be generally
accretive to the equity value per share of our stockholders and slightly
dilutive at the low end of the range and accretive to the equity value per share
at the middle to high end of the range. Based upon management derived estimates,
the same equity value per share analysis indicated that the Novation
transactions would be dilutive to the equity value per share only at the lowest
multiple of the range, and accretive to the equity value per share at each other
point calculated.

     TERMS OF LETTER AGREEMENT

     Pursuant to the terms of the Merrill Lynch letter agreement, we have agreed
to pay the following fees to Merrill Lynch for its financial advisory services
in connection with the Novation transactions:

     - a fee of $1,000,000, payable in cash upon the execution of a definitive
       agreement to effect the Novation transactions; and

     - if, during the period Merrill Lynch is retained by us or within one year
       thereafter, the transactions are consummated, or we enter into an
       agreement with Novation that subsequently results in the Novation
       transactions, an additional fee of $9,000,000, payable in cash upon the
       closing of the Novation transactions.

     We also have agreed to reimburse Merrill Lynch for all reasonable
out-of-pocket expenses incurred by Merrill Lynch in performing its services,
including the fees and expenses for legal counsel, and to indemnify Merrill
Lynch and related persons and entities against liabilities under federal or
state law arising out of a business combination contemplated by the letter
agreement or the engagement of Merrill Lynch pursuant to the letter agreement.

     In the ordinary course of business, Merrill Lynch and its affiliates may
actively trade in our securities for their own accounts and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities. In the past, Merrill Lynch has provided financial advisory
services and financing services to us, including acting as lead underwriter for
our initial public offering in January 2000 and acting as a financial advisor to
us in connection with our May 2000 acquisition of EquipMD, Inc.

OVERVIEW OF THE AGREEMENTS WITH NOVATION, VHA AND UHC

     Amended and Restated Outsourcing and Operating Agreement. On March 30,
2000, we entered into an outsourcing and operating agreement with Novation, VHA,
UHC and HPPI, which was amended and restated on May 24, 2000, in which we agreed
to adapt our existing online marketplace and develop a group of additional
websites to permit manufacturers and suppliers to offer equipment, products,
supplies, services, information and other content. Novation has agreed to act as
our exclusive agent to negotiate agreements with suppliers to offer their
equipment, products, supplies, services, information and content through our
online marketplace. VHA, HPPI, Novation and, subject to specified exceptions,
UHC have each agreed not to develop, promote, contract for the development of,
or assist others to develop or promote to their members, if applicable, any
other Internet-based exchange for the acquisition or disposal of medical
products, supplies, equipment or services by acute or non-acute healthcare
providers anywhere in the world.

     Amended and Restated Common Stock and Warrant Agreements. In consideration
for VHA's, UHC's and Novation's commitments under the amended and restated
outsourcing and operating agreement, we have agreed to issue shares of, and
warrants to purchase shares of, our common stock to VHA and UHC under the
amended and restated common stock and warrant agreements. Novation may terminate
the amended and

                                       15
<PAGE>   20

restated outsourcing and operating agreement if the amended and restated common
stock and warrant agreements are terminated.

     Amended and Restated Registration Rights Agreement. We intend to amend our
registration rights agreement with certain of our existing investors to extend
to each of VHA and UHC rights with respect to the shares of common stock to be
issued to each pursuant to the amended and restated common stock and warrant
agreements.

OUTSOURCING AND OPERATING AGREEMENT

     Neoforma to Develop its Online Marketplace. In the amended and restated
outsourcing and operating agreement, we agreed to develop our online marketplace
and create locations on it that are available only to users of HPPI and patrons
and members of VHA and UHC for their purchases. In connection with this
obligation, we agreed to:

     - provide our online marketplace with specified functionality that will
       facilitate members' use of our online marketplace;

     - create, host and implement specialty exchanges for the patrons and
       members of VHA, UHC and HPPI in phases including:

      - providing administration services that facilitate members' use of our
        online marketplace;

      - developing tools that permit suppliers to create and manage online
        catalogs of available products and services;

      - providing real-time, online reporting of transactions to Novation, VHA
        and UHC and their patrons and members; and

      - establishing a continuously available customer support center;

     - continue the availability of our existing auction services, asset
       management and recovery services and facility planning services; and

     - make remote order entry to our online marketplace possible for a
       specified number of healthcare facilities within a stated period, of
       which a specified number must be members of VHA and UHC, and of which a
       specified number must have made a stated dollar amount of healthcare
       purchases during the prior year.

The amended and restated outsourcing and operating agreement requires us to pay
liquidated damages to Novation if our online marketplace fails to achieve
required levels of functionality by specified target dates or to perform in
accordance with certain service levels. These liquidated damages are limited to
a specified amount in any month and a total cap for the entire term of the
agreement.

     Novation is Exclusive Agent to Negotiate Agreements with Suppliers. In the
amended and restated outsourcing and operating agreement, subject to some
exceptions, we appointed Novation as our exclusive agent to negotiate agreements
on our behalf under which the suppliers may offer their equipment, products,
supplies, services and information through our online marketplace. In connection
with this appointment, Novation has agreed to:

     - negotiate with suppliers within parameters established in consultation
       with us for inclusion of their equipment, products, suppliers, services
       and information on our online marketplace;

     - manage the commercial relationships between these suppliers and our
       online marketplace; and

     - subject to stated Neoforma obligations, by a specified date, obtain
       agreements on our behalf with suppliers who together made a stated
       percentage of all sales during the prior year under group purchasing
       contracts that Novation negotiated for the benefit of VHA, UHC, their
       members and patrons.

     Fees for Sales on Our Online Marketplace. Suppliers will pay a percentage
of the value of transactions for their use of our online marketplace, and these
transaction fees will be shared between us and Novation in varying proportions
depending on the type of transaction and the purchaser. We will receive all of
the

                                       16
<PAGE>   21

transaction fees generated from suppliers for products or services purchased on
our online marketplace under Novation contracts up to a specified minimum
percentage of the adjusted gross transaction value of such purchases and will
share transaction fees generated above the specified minimum percentage with
Novation. For an initial period of the agreement, Novation has agreed that we
will receive this specified minimum percentage if the fees generated from
suppliers are less than the specified minimum percentage. We will share
transaction fees generated from the sale of non-contracted products and services
on our online marketplace with Novation in varying proportions depending on
whether or not the purchaser is a patron or member of Novation, VHA, UHC or
HPPI. We will not share any transaction fees generated from the sale of products
or services on our online marketplace under contracts with another group
purchasing organization. Until a specified date, Neoforma will not be required
to share any fees with Novation in any quarter until minimum aggregate
transaction fee levels for that quarter have been met. Novation will also be
entitled to receive a portion of specified revenue from our Plan and Auction
services generated through the Novation relationship.

     Global Exclusivity. Each of Novation, VHA, UHC and HPPI has agreed that it
will not develop, promote, contract for the development of, or assist others to
develop or promote to their members, and we have agreed that we will not
develop, promote, contract for the development of, or assist others to develop
or promote, any internet-based systems related to acquisition or disposal of
products, supplies, equipment, information or services by acute or non-acute
healthcare providers anywhere in the world other than our online marketplace;
except that in the case of UHC, certain limited categories of products and
services are excluded from this obligation. We have also agreed that Novation
will be our exclusive agent to negotiate with suppliers for the inclusion of
their products, supplies, equipment, services or information on our online
marketplace, subject to some exceptions. We may generally not negotiate
agreements with suppliers directly or contract with or pay financial incentives
to any other person to do so, except that we may negotiate agreements with
suppliers which Novation declines to sign up to our online marketplace or with
suppliers that insist on dealing directly with us or with respect to suppliers
of another group purchasing organization that has expressly conditioned its
participation in the online marketplace on us negotiating agreements with our
suppliers.

     Novation and we have also agreed that if either wants to create an internet
venture outside the United States or serve any healthcare market, such as
veterinary medicine, that is not then served on our online marketplace, it will
first offer the other the opportunity to participate in the venture in a manner
commensurate with its role under the amended and restated outsourcing and
operating agreement. If a party refuses such offer, then the offering party may
proceed with the venture alone or with another partner. Additionally, UHC will
give favorable consideration to using us as its provider of internet-related
services outside the scope of the amended and restated outsourcing and operating
agreement if such services are available primarily through us. Notwithstanding
this, UHC will not be obligated to use us as the provider of such services.

     Marketing Assistance. Novation, VHA and UHC have each agreed to assist us
in marketing its existing auction services, asset management and recovery
services and facility planning services to their members.

     Guaranties of Performance. Each of VHA and UHC will have responsibility for
Novation's obligations under the amended and restated outsourcing and operating
agreement so that any liability related primarily to VHA's or UHC's obligations
will be that party's responsibility and liability for any other of Novation's
obligations will be shared between VHA and UHC in proportion to their ownership
interest in Novation.

     Term and Termination. The amended and restated outsourcing and operating
agreement has an initial term of ten years, but automatically renews for
successive one-year terms thereafter, unless we or Novation provide written
notice of termination. The agreement can also be terminated:

     - by either party if the other materially breaches its service obligations;

     - by either party, if the other breaches its exclusivity obligations;

     - by Novation, if the common stock and warrant agreements with VHA and UHC
       are terminated, including upon the failure of our stockholders to approve
       the issuance of our stock and warrants to purchase our stock to VHA and
       UHC; or

                                       17
<PAGE>   22

     - by Novation, before the issuance of shares under the common stock and
       warrant agreements, if there is a change of control of Neoforma.

COMMON STOCK AND WARRANT AGREEMENTS

     In connection with the amended and restated outsourcing and operating
agreement, we entered into common stock and warrant agreements, which were
subsequently amended and restated, with each of VHA and UHC to issue 46,267,530
shares of our common stock to VHA and 11,279,150 shares of our common stock to
UHC. We will not receive any cash payment from VHA or UHC for these shares; we
are issuing the shares of our common stock to VHA and UHC, together with
warrants to purchase our common stock, in consideration for VHA's, UHC's and
Novation's commitments under the amended and restated outsourcing and operating
agreement. The amended and restated common stock and warrant agreements are
attached to this proxy statement as Annex B and Annex C.

     For each of the next four years, on April 1, 2001, 2002, 2003 and 2004,
16.75% of the shares of our common stock issued to VHA will be subject to
forfeiture to us if:

     - for the one-year period ending on each of January 31, 2001, 2002, 2003,
       and 2004, both the cumulative number of healthcare organizations that are
       members or patrons of VHA that have signed up for our services and did
       not terminate their contracts with us is lower than the target number
       specified for the year; and

     - the cumulative aggregate dollar volume of historical purchases of
       products by such healthcare organizations is less than the specified
       target purchasing volume for that year.

     For the first five years after the common stock has been issued to VHA, and
for as long after this five-year period as VHA holds more than 35% of our common
stock, VHA has agreed that it will vote all shares of our common stock that VHA
holds in excess of 19.9% of our common stock in proportion to the votes cast by
all of our other stockholders, except for votes concerning a change of control
of Neoforma, the election of VHA's nominee or nominees to our board of directors
or an amendment to our certificate of incorporation that would adversely affect
VHA in a manner different from its effect on other stockholders. Similarly, for
the first five years after the common stock has been issued to UHC, and for as
long after this five-year period as UHC holds more than 9% of our common stock,
UHC will vote all shares of our common stock that UHC holds in excess of 9% of
our common stock in proportion to the votes cast by all of our other
stockholders, except for votes on a change of control of Neoforma or an
amendment to our certificate of incorporation that would adversely affect UHC in
a manner different from its effect on the other stockholders.

     VHA has agreed that for the first five years after the common stock has
been issued to VHA, and for as long after this five-year period as VHA holds
more than 35% of our common stock, VHA will not, without our consent, acquire
our securities that, together with those held by it and its affiliates, will
exceed 24% of our common stock, other than upon exercise of the warrant issued
to VHA. UHC has agreed that for the first five years after the common stock has
been issued, and for as long after this five-year period as UHC holds at least
9% of our common stock, UHC will not, without our consent, acquire our
securities that, together with those held by it and its affiliates, will exceed
9% of our common stock, other than upon exercise of the warrant issued to UHC.
VHA has further agreed that it will not sell or transfer its shares of our
common stock to another person, if after such sale or transfer, this person
would own 15% or more of our outstanding common stock, unless the transferee
agrees in writing to be bound to the same voting and acquisition restrictions
that VHA is subject to, except that, for transferees, the 19.9% voting
limitation and the 24% transfer limitation will each be adjusted to 15%.

     Representations and Warranties. The amended and restated VHA and UHC common
stock and warrant agreements contain customary representations and warranties by
VHA, UHC and us, respectively, regarding

                                       18

     The representations and warranties in the amended and restated common stock
and warrant agreements are complicated and are not easily summarized. We urge
you to read the sections of the amended and restated common stock and warrant
agreements entitled "Representations and Warranties of Parent,"
"Representations, Warranties and Certain Agreements of VHA" and
"Representations, Warranties and Certain Agreements of UHC" of the respective
documents carefully.

     Right to Elect Directors. If our stockholders approve the issuance of our
common stock and warrants to purchase our common stock to VHA and UHC, VHA will
have the right to designate two Class I directors following this annual meeting.
For so long as VHA holds 10% or more of our common stock, including the shares
issuable upon exercise of its warrant, VHA will have the right to designate one
member of our board of directors. For so long as VHA holds 20% or more of our
common stock, including the shares issuable upon exercise of its warrant, VHA
will have the right to designate two members of our board of directors. If our
stockholders approve the issuance of our common stock and warrants to purchase
our common stock to VHA and UHC, and our board of directors subsequently
establishes an executive or similar committee, VHA will have the right to
designate one member of this committee. For the longer of six years after the
date of the amended and restated common stock and warrant agreement, or for as
long as UHC owns more than 9% of our common stock, UHC will have the right to
nominate a person to our board of directors if we issue to a group purchasing
organization equity securities equal to or less than the amount issued to UHC,
or enter into a commercial relationship with a group purchasing organization
having a lower historical purchasing volume than UHC, and we give this group
purchasing organization the right to nominate a person to our board of
directors.

     Closing Conditions. The amended and restated VHA and UHC common stock and
warrant agreements contain customary conditions to issue the common stock and
warrants according to their respective agreements. These closing conditions,
among other things, include the following:

     - the representations and warranties are true;

     - the parties will have performed all obligations under the agreements;

     - the shares will be exempt from registration under federal and state
       securities laws;

     - the receipt of all required approvals and consents;

     - the shares and shares issuable upon exercise of the warrants will be
       approved for listing on the Nasdaq Stock Market;

     - the amended and restated outsourcing and operating agreement will have
       been executed; and

     - our stockholders will have approved the transactions.

     Restrictions on Proposals. Subject to certain exceptions, we have agreed in
our agreements with VHA and UHC not to solicit, participate in any negotiations,
endorse or approve, or enter into any agreement regarding, a proposal for the
acquisition by an outside party of 50% or more of our assets or outstanding
stock. Similarly, VHA and UHC have agreed in their respective agreements not to
solicit, participate in any negotiations, endorse or approve, or enter into any
agreement regarding, a proposal that would constitute a breach by VHA or UHC of
their exclusivity obligations under the amended and restated outsourcing and
operating agreement.

     Termination. The amended and restated common stock and warrant agreements
may be terminated by their respective parties for specific reasons, including
the following:

     - mutual consent of the parties;

     - by either party if the closing of the stock and warrant issuances has not
       occurred by September 30, 2000;

     - by either party if a government entity has issued a final order
       prohibiting the transactions;

     - by either party if our stockholders do not approve the transactions;

                                       20
<PAGE>   25

     - by either party if the amended and restated outsourcing and operating
       agreement is terminated; or

     - by VHA and UHC, respectively, if:

      - our board of directors withdraws or amends its recommendation in favor
        of the Novation transactions;

      - our board of directors fails to include a recommendation in favor of the
        Novation transactions in this proxy statement;

      - our board of directors, once requested by VHA or UHC, fails to reaffirm
        its recommendation in favor of the Novation transactions following a
        public announcement regarding the sale of more than 50% of our
        outstanding stock or assets;

      - our board of directors approves or publicly recommends a proposal
        regarding the sale of more than 50% of our outstanding stock or assets;

      - our board of directors enters into a letter of intent or similar
        agreement regarding the sale of more than 50% of our outstanding stock
        or assets; or

      - we materially breach our obligation to hold our stockholders meeting or
        refrain from soliciting other offers or proposals.

     We may be obligated to pay VHA a termination fee of $12.0 million if the
amended and restated common stock and warrant agreement is terminated, either
for the reasons stated in the last major bullet point in the section immediately
above describing events that could terminate the amended and restated common
stock and warrant agreements, or if:

     - prior to our stockholders meeting, there is a publicly announced proposal
       involving a transaction to acquire or purchase more than 50% of our
       assets or outstanding stock; and

     - the amended and restated common stock and warrant agreement is terminated
       because our stockholders do not approve the transactions; and

     - within nine months after the termination, we enter into or complete the
       alternative transaction.

     For a more complete description of the payment of termination fees, see
Section 9.3 of the amended and restated common stock and warrant agreement
between us and VHA, entitled "Parent Payment."

     We may be obligated to pay UHC a termination fee of $3.0 million if the
amended and restated common stock and warrant agreement is terminated, either
for the reasons stated in the last bullet point in the section above describing
events that could terminate the amended and restated common stock and warrant
agreements, or if:

     - prior to our stockholders meeting, there is a publicly announced proposal
       involving a transaction to acquire or purchase more than 50% of our
       assets or outstanding stock; and

     - the amended and restated common stock and warrant agreement is terminated
       because our stockholders do not approve the transactions; and

     - within nine months after the termination, we enter into or complete the
       alternative transaction.

     For a more complete description of the payment of termination fees, see
Section 9.3 of the common stock and warrant agreement between us and UHC,
entitled "Parent Payment."

     Warrants. Under the amended and restated common stock and warrant
agreements, we will issue a warrant to VHA to purchase 30,845,020 shares of our
common stock and to UHC to purchase 7,519,436 shares of our common stock. These
warrants have an exercise price of $0.01 per share and a term of ten years. The
shares issuable under each of the warrants are divided into two groups, Tranche
A and Tranche B, each of which have specified cumulative purchasing volume
dollar targets for each of June 30, 2001, 2002, 2003 and 2004. These cumulative
purchasing volume dollar targets increase each year. For Tranche A shares, if
the specified target is not met, a pro rata number of shares will vest based
upon the portion of the target met, and

                                       21
<PAGE>   26

the shortfall amount will vest only if the following year's target is met in its
entirety. For Tranche B shares, if the specified target is not met, a pro rata
number of shares will vest based upon the amount by which the Tranche A target
for such date is exceeded, and the Tranche B shortfall amount will vest only if
the following year's target is met in its entirety. The warrants become
exercisable as to all shares if a merger, business combination or other
transaction occurs in which our common stock is converted into cash or if a cash
tender offer for all of our common stock is consummated. If the warrants
terminate, and the warrants are then exercisable, the warrants will be
automatically exercised and the exercise price paid by surrender to us of a
number of shares of common stock with a market value equal to the exercise
price.

AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT

     We are currently a party to a registration rights agreement with certain of
our stockholders, and have agreed with VHA and UHC to use our reasonable best
efforts to have these stockholders permit us to enter into an amended and
restated registration rights agreement with VHA, UHC and these stockholders
which would grant rights with respect to the registration of their shares of our
common stock under the Securities Act, as described below.

     Demand Registration Rights. Beginning on January 24, 2001, these
stockholders have the right to request that we file a registration statement so
that they can publicly sell all or a portion of their shares if either the
current market value of the VHA and UHC shares to be included in the
registration statement is at least $30.0 million, or the shares to be registered
constitutes at least 60% of the shares issued upon conversion of our Series E
and E-1 preferred stock or 75% of all of our common stock with registration
rights, and the shares will likely sell to the public for at least $20 million.
We will be required to file three registration statements in response to the
demand registration rights of stockholders holding our common stock issued in
connection with the Novation transactions, two registration statements in
response to a demand by the holders of at least 60% of the stock converted from
the Series E and E-1 preferred stock, and an additional two registration
statements in response to stockholder's demand registration rights generally. We
may postpone the filing of a registration statement for up to 90 days once in a
12-month period if our board of directors determines that the filing would be
seriously detrimental to us or our stockholders.

     Piggyback Registration Rights. If we register our securities for public
sale, these stockholders have the right to include their shares in the
registration statement. However, this right does not apply to a registration
relating to any of our employee benefit plans, a corporate reorganization or any
demand registration pursuant to the registration rights agreement. The managing
underwriter of any underwritten offering will have the right to limit the number
of our shares registered by these stockholders, other than VHA and UHC, to 15%
of the total shares covered by the registration statement due to marketing
reasons. This limitation, however, will not reduce the number of shares to be
registered for VHA below 15%, for UHC below 5%, and for Series E and E-1
preferred stock below 12%, of the total number of shares included in the
registration statements for the first and second of these offerings. In any
subsequent offering, the reduction of shares to be registered will not be below
9.5% for VHA and 3.5% for UHC of the total number of shares included in that
registration statement.

     S-3 Registration Rights. If we are eligible to file a registration
statement on Form S-3 and if the aggregate price of the shares to be offered to
the public is at least $1.0 million, stockholders holding at least 1% of our
common stock with registration rights, any stockholder holding shares of our
common stock issued upon conversion of our Series E and E-1 preferred stock, and
each of VHA and UHC can request that we file a registration statement on Form
S-3 covering the resale of these shares. We are not required to file a
registration statement more than once in a 12-month period on Form S-3 for each
of the following: the holders of our securities with registration rights as a
group; the holders of conversion shares for our Series E and E-1 preferred
stock; and the holders of common stock issued to UHC in the Novation
transactions. We are not required to file a registration statement more than
twice in a 12-month period on Form S-3 for the holders of common stock issued to
VHA in the Novation transactions.

                                       22
<PAGE>   27

     Expenses of Registration. We will generally pay all registration expenses
relating to all demand and piggyback registrations, and relating to the first
three Form S-3 registrations, except for underwriter's and brokers' discounts
and commissions, which will be paid by the participating stockholders.

     Expiration of Registration Rights. These registration rights will expire
with respect to a particular stockholder if all of its shares of common stock
may be sold in a three-month period pursuant to Rule 144 of the Securities Act.
In any event, the registration rights described above will expire on September
30, 2005.

     If we are unable to enter into an amended and restated registration rights
agreement having these terms, we have agreed with VHA and UHC to grant to VHA
and UHC registration rights as similar to these rights as possible.

VOTING AGREEMENTS

     Nine of our stockholders, including each of our directors or entities
affiliated with them, have entered into voting agreements with VHA and UHC as an
inducement for VHA and UHC to enter into their respective transactions with us.
Under the voting agreements, these stockholders have agreed to vote a portion of
their respective shares of our common stock equal to, in the aggregate, a total
of approximately 25% of our outstanding shares at any Neoforma stockholders
meeting or in any action taken by the written consent of our stockholders:

     - in favor of the issuance of shares of our common stock, warrants to
       purchase our common stock, and the shares of our common stock issuable
       under the warrants, and all actions required by the amended and restated
       common stock and warrant agreements; and

     - against approval of any action or agreement which would result in a
       breach of any covenant, representation or warranty or any other
       obligation or agreement by us under the amended and restated common stock
       and warrant agreements, or by the stockholders under the voting
       agreement.

     None of the persons who entered into a voting agreement were paid
additional consideration in connection with the voting agreements. The voting
agreements will terminate upon the earlier of the closing of the transactions or
the valid termination of the amended and restated common stock and warrant
agreements in accordance with its terms.

PRO FORMA CAPITALIZATION


     On June 23, 2000, there were 69,017,590 shares of our common stock
outstanding. The following table represents the potential number and percentage
of our common stock that could be beneficially owned by VHA and UHC after
completion of the issuance of securities in connection with the Novation
transactions. The first two columns represent only the issuance of our common
stock at closing. The second two columns assume that all options and warrants
outstanding on June 23, 2000, including the warrants to be issued to VHA and
UHC, will be fully exercised, that none of the shares issued to VHA will be
forfeited, that VHA and UHC will achieve all performance-based milestones in
their respective warrants and that VHA and UHC will not distribute their shares
to any of their members or patrons or otherwise.

                                 PROPOSAL NO. 3

             APPROVAL OF AMENDMENT TO CERTIFICATE OF INCORPORATION

     Our certificate of incorporation currently authorizes us to issue up to
200,000,000 shares of common stock and 5,000,000 shares of preferred stock. This
proposal would amend the certificate of incorporation to authorize us to issue
up to 300,000,000 shares of common stock and the number of shares of preferred
stock would remain unchanged. A copy of the form of amended and restated
certificate of incorporation is attached to this proxy statement as Annex D. The
larger number of authorized shares of common stock provided for in this proposal
will provide us the certainty and flexibility to undertake various types of
transactions, including stock splits, in the form of stock dividends,
financings, increases in the shares reserved for issuance pursuant to stock
incentive plans, or other corporate transactions not yet determined.


     As of the record date, there were 200,000,000 shares of common stock
authorized, approximately 69,017,590 issued and outstanding shares of our common
stock, approximately 8,192,393 shares reserved for issuance upon exercise of
stock options granted under our stock option plans, approximately 6,284,276
shares reserved for issuance under our 1999 Equity Incentive Plan, 750,000
shares reserved for issuance for purchases under our 1999 Employee Stock
Purchase Plan, 1,081,793 shares reserved for issuance upon exercise of stock
options that were assumed in the acquisitions of EquipMD, Inc., and Pharos
Technologies, Inc. and 898,147 shares subject to issuance upon the exercise of
outstanding warrants. In addition, if Proposal No. 2 is approved, we will issue
approximately 57,546,680 shares of common stock to VHA and UHC and will issue
warrants to purchase an additional 38,364,456 shares of common stock to VHA and
UHC. If the proposed increase in the number of authorized shares of common stock
from 200,000,000 to 300,000,000 shares were approved, we would then have
117,864,665 shares of common stock available for issuance in the future.


     Our board of directors believes that the availability of additional
authorized shares of common stock will provide us with the ability to respond to
future circumstances with a reasonable degree of flexibility. These
circumstances might include acquiring other companies, raising equity capital,
adoption of additional employee benefit plans or reservation of additional
shares for issuance under these plans or other proper corporate purposes. Under
the proposed amendment to the certificate of incorporation, the additional
shares of common stock would be available for issuance without further
stockholder action, unless stockholder action is otherwise required by Delaware
law or the rules of any stock exchange or automated quotation system on which
the common stock may then be listed or quoted.

     Should our board of directors elect to issue additional shares of common
stock, existing stockholders would not have any preferential or preemptive
rights to purchase shares. Therefore, additional issuances of common stock could
have a dilutive effect on the earnings per share, voting power and stock
holdings of current stockholders. The additional shares of common stock that
would become available for issuance if the proposed amendment were adopted could
also be used by us to oppose a hostile takeover attempt or delay or prevent
changes of our control or changes in or removal of our management. For example,
without further stockholder approval, the board could strategically sell shares
of common stock in a private transaction to purchasers who would oppose a
takeover or favor the current board. Although this proposal to increase the
number of authorized shares of common stock has been prompted by business and
financial considerations, not by the threat of any attempt to accumulate shares
or otherwise gain control of us, stockholders nevertheless should be aware that
approval of the proposal could facilitate future efforts by us to deter or
prevent changes of our control, including transactions that are favored by a
majority of the independent stockholders or in which the stockholders might
otherwise receive a premium for their shares over then-current market prices or
benefit in some other manner.

                                       24
<PAGE>   29

     In addition, the authority granted by our certificate of incorporation to
the board to fix the designations, powers, preferences, rights, qualifications,
limitations and restrictions of any class or series of our preferred stock could
be used for anti-takeover purposes. The proposal to increase the number of
authorized shares of common stock, however, is not part of any plan to adopt a
series of amendments having an anti-takeover effect, and our management
presently does not intend to propose anti-takeover measures in future proxy
solicitations.

                THE BOARD RECOMMENDS A VOTE "FOR" THE AMENDMENT
                      TO OUR CERTIFICATE OF INCORPORATION.

                                 PROPOSAL NO. 4

               RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     We have selected Arthur Andersen LLP as our independent auditors to perform
the audit of our financial statements for the year ending December 31, 2000, and
the stockholders are being asked to ratify this selection. Representatives of
Arthur Andersen LLP are expected to be present at the annual meeting, will have

               COMPENSATION ARRANGEMENTS WITH EXECUTIVE OFFICERS

     Mr. Zollars. In July 1999, we entered into an at-will employment agreement
with Robert J. Zollars for him to serve as our Chairman, President and Chief
Executive Officer. Under this agreement, Mr. Zollars receives a salary equal to
$500,000 for the first year of the agreement, which can be increased by us in
subsequent years. Mr. Zollars received a $250,000 bonus in December 1999.
Beginning in 2000 and for each following year while he is employed by us, Mr.
Zollars is eligible to receive a bonus payment of at least $500,000 for that
fiscal year, based upon whether we achieve revenue and profitability targets
and/or other organizational milestones to be specified by our board of
directors.

     Upon entering into this employment agreement, Mr. Zollars received an
option to purchase 1,637,160 shares of our common stock and an option to
purchase 3,602,315 shares of our common stock, each at an exercise price of
$0.10 per share. Both options were immediately exercisable and Mr. Zollars
exercised these options in full in July 1999. All of the shares purchased under
the option for 3,602,315 shares were subject to a repurchase right that lapses
at a rate of 900,578 shares after his first year of employment and 75,048 shares
per month thereafter. If we are acquired or if certain changes in control of
Neoforma occur, the then unvested portion of his option will become vested.

     Mr. Zollars is eligible to receive from us a moving assistance loan of $2.5
million, which will be forgiven in equal monthly installments on the last day of
each month from the date of closing on his new home through June 30, 2003. As of
June 16, 2000, Mr. Zollars has not exercised this benefit. Mr. Zollars also has
the right to be reimbursed by us up to $300,000 for any loss on the sale of his
previous home. We are obligated to reimburse Mr. Zollars for an additional
$338,000 plus additional moving expenses incurred in connection with his joining
us.

     If Mr. Zollars' employment is terminated other than for disability or
cause, or if Mr. Zollars resigns for good reason, he will be entitled to receive
an amount equal to his annual salary, bonus and benefits. In addition, our right
to repurchase all outstanding stock held by Mr. Zollars will lapse and the
forgiveness of the home loan will be treated as if he had been employed by us
for 12 additional months after the termination of employment. Good reason
includes a reduction in his duties or responsibilities or a reduction in his
salary, bonus or other benefits.

     Mr. Ruegsegger. In June 1999, we entered into an offer letter with
Frederick J. Ruegsegger for him to serve as our Chief Financial Officer. Under

common stock at $0.50 per share. This option is immediately exercisable and Mr.
Ruegsegger has exercised the option in full. All of the shares underlying the

vest over four years, with one fourth of the shares vesting at the end of the
first year of employment with us and an additional one forty-eighth vesting each
month thereafter, for so long as he is employed by us. If Mr. Ruegsegger's
employment is terminated other than for cause, he will be entitled to receive an
amount equal to three months of his salary. In addition, in the event of a
change of control of Neoforma and termination of Mr. Ruegsegger's employment,
50% of the then unvested portion of Mr. Ruegsegger's option shall immediately
vest.

     Mr. Goel. In September 1999, we entered into an offer letter with Bhagwan
D. Goel for him to serve as our Executive Vice President of Products and
Services. Under this offer letter, Mr. Goel receives a salary equal to $225,000

receive a bonus of $50,000 after one year of employment. Upon entering into
employment with us, Mr. Goel received an option to purchase 595,000 shares of
our common stock at $3.00 per share. This option is immediately exercisable and
Mr. Goel has exercised the option in full. As of June 16, 2000, 495,834 of the
shares underlying the option were subject to a right of repurchase. The shares
underlying the option vest in equal monthly installments over four years, for so

     Mr. Capsuto. As a result of our acquisition of EquipMD in April 2000, we
entered into an employment agreement with Allen M. Capsuto for him to serve as
one of our officers. In May 2000, Mr. Capsuto was appointed as Senior Vice
President, Physician Business. Under his employment agreement, Mr. Capsuto
receives a salary equal to $225,000 per year. Mr. Capsuto is eligible to receive

                      REPORT OF THE COMPENSATION COMMITTEE

     Under Item 402(a)(9) of Regulation S-K promulgated by the Securities and
Exchange Commission, neither the "Report of the Compensation Committee" nor the
material under the caption "Performance Graph" shall be deemed to be filed with
the SEC for purposes of the Securities Exchange Act of 1934, nor shall the
report or the graph be deemed to be incorporated by reference in any past or
future filing by the Company under the Securities Exchange Act of 1934, or the
Securities Act of 1933.

     The Compensation Committee of the board of directors administers our
executive compensation program. Prior to our initial public offering in January
2000, our executive compensation program was administered by the full board of
directors. The current members of the Compensation Committee are David L.
Douglass, Andrew J. Filipowski and Richard D. Helppie. Each of these persons is
a non-employee director within the meaning of Section 16 of the Securities
Exchange Act of 1934, and an "outside director" within the meaning of Section
162(m) of the Internal Revenue Code. None of these individuals has at any time
been one of our officers or employees. For a description of the transactions
between us and members of the compensation committee and entities affiliated
with the compensation committee members, see "Certain Relationships and Related
Transactions." Robert J. Zollars, our President and Chief Executive Officer, is
a member of the board of directors of divine interVentures, inc., of which Mr.
Filipowski is President, Chief Executive Officer and Chairman of the board of
directors.

GENERAL COMPENSATION PHILOSOPHY

     The role of the compensation committee is to set the salaries and other
compensation of our executive officers and other key employees, and to make
grants under, and to administer, our stock option and other employee equity and
bonus plans. Our compensation philosophy for executive officers is to relate
compensation to corporate performance and increases in stockholder value, while
providing a total compensation package that is competitive and enables us to
attract, motivate, reward and retain key executives and employees. Accordingly,
each executive officer's compensation package may, in one or more years, be
comprised of the following three elements:

     - base salary that is designed primarily to be competitive with base salary
       levels in effect at high technology companies in the Silicon Valley that
       are of comparable size to us and with which we compete for executive
       personnel;

     - annual variable performance awards, such as bonuses, payable in cash and
       tied to the achievement of performance goals, financial or otherwise; and

     - long-term stock-based incentive awards, which strengthen the mutuality of
       interests between the executive officers and our stockholders.

EXECUTIVE COMPENSATION

     Base Salary. Salaries for executive officers for 1999 were generally
determined on an individual basis in connection with the executive officer's
acceptance of employment with us by evaluating each executive's scope of
responsibility, performance, prior experience and salary history, as well as the
salaries for similar positions at comparable companies.

     Quarterly Incentive Awards. We provide quarterly incentive bonuses to
certain employees, including executive officers, pursuant to the terms of the
offer letters they enter into upon accepting employment with us. Target bonuses
are generally established based on a percentage of base salary and become
payable upon the achievement of specified goals and personal and team objectives
established by the employee's manager. At the end of the quarter, performance is
assessed and the level of bonus payable, if any, is determined.

     Long-Term Incentive Awards. The compensation committee believes that
equity-based compensation in the form of stock options links the interests of
executive officers with the long-term interests of our stockholders and
encourages executive officers to remain in our employ. Stock options generally
have value for

                                       34
<PAGE>   39

executive officers only if the price of our stock increases above the fair
market value on the grant date and the officer remains in our employ for the
period required for the shares to vest.

     Other Compensation. Our executive officers are also eligible to participate
in compensation and benefit programs generally available to other employees,
including our Employee Stock Purchase Plan.

     We grant stock options in accordance with our 1999 Equity Incentive Plan
and previously, our 1997 Stock Plan. Stock options typically have been granted
to executive officers when the executive first joins us. The compensation
committee may, however, grant additional stock options to executive officers in
connection with a change in responsibilities, to achieve equity within a peer
group, as a retention device or to align their interests with stockholders for
other reasons. The number of shares subject to each stock option granted is
within the discretion of the compensation committee and is based on anticipated
future contribution and ability to impact our results, past performance or
consistency within the officer's peer group. At the discretion of the
compensation committee, executive officers may also be granted stock options to
provide greater incentives to continue their employment with us and to strive to
increase the value of our common stock. The stock options generally become
exercisable over a four-year period and are granted at a price that is equal to
the fair market value of our common stock on the date of grant.

CHIEF EXECUTIVE OFFICER COMPENSATION

     Mr. Zollars' initial base salary, target bonus, bonus paid and long-term
incentive awards were determined by the terms of his employment agreement
entered into upon his acceptance of employment with us in July 1999. The
compensation committee will review Mr. Zollars' compensation annually in a
manner consistent with the factors described above for all executive officers.

INTERNAL REVENUE CODE SECTION 162(M) LIMITATION

     Section 162(m) of the Internal Revenue Code limits the tax deduction to
$1.0 million for compensation paid to executives of public companies. The
compensation committee has considered the potential impact of the requirements
of Section 162(m) on the compensation paid to our executive officers. The
compensation committee's present intention is to comply with Section 162(m)
unless the compensation committee feels that required changes would not be in
the best interest of us or our stockholders.

there was no public trading market for our common stock during the fiscal year
ended December 31, 1999.

     - in which any director, executive officer, holder of more than 5% of our
       common stock or any member of their immediate family had or will have a
       direct or indirect material interest.

In addition, in October 1999, we entered into an agreement with Superior
Consultant Company, Inc., a wholly owned subsidiary of Superior Consultant
Holdings Corporation, providing for collaboration between us and Superior.
Superior is a supplier of Digital Business Transformation(TM) services to large
healthcare organizations, including Internet-related services, systems
integration, outsourcing and consulting, which enable Superior clients to
utilize digital technologies and process innovations to improve their
businesses. Under the agreement, we have agreed to market Superior's services to

<PAGE>   42

our services into its Digital Business Transformation(TM) offerings. The
agreement also provides for joint marketing activities. In consideration, we
have agreed to make payments to Superior in an aggregate amount of up to
approximately $2.0 million, as well as a percentage of specified Neoforma
e-commerce transaction revenue and other potential fixed payments based on the
success of the joint marketing activities. We have also agreed to utilize
Superior's services on a preferred basis for systems integration, development,

fees. Our agreement with Superior expires in October 2002.

portables, workstations, servers and storage devices unless its products did not
meet our reasonable technical requirements. We also agreed to purchase at least
$5.0 million of Dell products and $100,000 of data center consulting services.

parties. All future transactions between us and our officers, directors and
principal stockholders and their affiliates will be approved by a majority of
the board, including a majority of the independent and disinterested directors

Board of Directors
Neoforma.com, Inc.
3255-7 Scott Boulevard
Santa Clara, California 95054

Members of the Board of Directors:

     Neoforma.com, Inc. (the "Company") proposes to enter into several related
transactions (collectively, the "Transaction"); (a) the establishment of a ten
year mutual outsourcing arrangement and co-branded E-commerce site (the
"Novation Arrangement") pursuant to an Amended and Restated Outsourcing and
Operating Agreement, dated as of May 24, 2000 (the "Outsourcing and Operating
Agreement"), among Novation, LLC ("Novation"), VHA, Inc. ("VHA"), University
Healthsystem Consortium Services Corporation ("UHC"), Healthcare Purchasing
Partners International, LLC, and the Company, (b) the issuance by the Company to
VHA, pursuant to an Amended and Restated Common Stock and Warrant Agreement by
and between the Company and VHA amended and restated as of May 24, 2000 (the
"VHA Common Stock and Warrant Agreement"), of 46,267,530 shares of its common
stock, par value $0.0001 per share ("Company Common Stock"), subject to certain
forfeiture provisions, and of a warrant to acquire an additional 30,845,020
shares of Company Common Stock which vests over a five year period if certain
performance criteria are met, and (c) the issuance by the Company to UHC,
pursuant to an Amended and Restated Common Stock and Warrant Agreement by and
between the Company and UHC amended and restated as of May 24, 2000 (the "UHC
Common Stock and Warrant Agreement"), of 11,279,150 shares of Company Common
Stock and of a warrant to acquire an additional 7,519,436 shares of Company
Common Stock which vests over a five year period if certain performance criteria
are met.

     You have asked us whether, in our opinion, the Transaction is fair from a
financial point of view to the Company.

     In arriving at the opinion set forth below, we have, among other things:

     (1) Reviewed certain publicly available business and financial information
         relating to Novation and the Company that we deemed to be relevant;

     (2) Reviewed certain information, including financial forecasts, relating
         to the business, earnings, revenue, cash flow, assets, liabilities and
         prospects of the Company furnished to us by the Company as well as
         projected cash flows for the Novation Arrangement furnished to us by
         the Company and Novation;

     (3) Conducted discussions with members of senior management of Novation and
         the Company concerning the matters described in clauses 1 and 2 above,
         as well as the business and prospects of the Company in the case of the
         Company's senior management, and the business and prospects of the
         Novation Arrangement in the case of Novation management, before and
         after giving effect to the Transaction;

                                       A-1
<PAGE>   46

     (4) Participated in certain discussions and negotiations among
         representatives of Novation and the Company and their financial and
         legal advisors;

     (5) Reviewed the potential pro forma impact of the Transaction;

     (6) Reviewed the Outsourcing and Operating Agreement, the VHA Common Stock
         and Warrant Agreement and the UHC Common Stock and Warrant Agreement;
         and

     (7) Reviewed such other financial studies and analyses and took into
         account such other matters as we deemed necessary, including our
         assessment of general economic, market and monetary conditions.

     In preparing our opinion, we have assumed and relied on the accuracy and
completeness of all information supplied or otherwise made available to us,
discussed with or reviewed by or for us, or publicly available, and we have not
assumed any responsibility for independently verifying such information or
undertaken an independent evaluation or appraisal of any of the assets or
liabilities of the Company or been furnished with any such evaluation or
appraisal. In addition, we have not assumed any obligation to conduct any
physical inspection of the properties or facilities of the Company. With respect
to the financial forecast information for the Company furnished to or discussed
with us by the management of the Company, and the financial forecast information
for the Novation Arrangement furnished to or discussed with us by the management
of Novation and the management of the Company, we have assumed that they have
been reasonably prepared and reflect the best currently available estimates and
judgment of such management as to the expected future financial performance of
such entity, as the case may be.

     Our opinion is necessarily based upon market, economic and other conditions
as they exist and can be evaluated on, and on the information made available to
us as of, the date hereof. We have assumed that in the course of obtaining the
necessary regulatory or other consents or approvals (contractual or otherwise)
for the Transaction, no restrictions, including any divestiture requirements or
amendments or modifications, will be imposed that will have a material adverse
effect on the contemplated benefits of the Transaction.

     We are acting as financial advisor to the Company in connection with the
Transaction and will receive a fee from the Company for our services, a
significant portion of which is contingent upon the consummation of the
Transaction.

     In addition, the Company has agreed to indemnify us for certain liabilities
arising out of our engagement. We are currently acting as financial adviser to
the Company in connection with its consideration of other strategic initiatives,
and have, in the past, provided financial advisory and financing services to the
Company, including acting as lead managing underwriter for the Company's initial
public offering in January 2000 and as financial adviser to the Company for its
May 2000 acquisition of EquipMD, and may continue to do so and have received,
and may receive, fees for the rendering of such services.

     In addition, in the ordinary course of our business, we may actively trade
securities of the Company for our own account and for the accounts of customers
and, accordingly, may at any time hold a long or short position in such
securities.

     This opinion is for the use and benefit of the Board of Directors of the
Company. Our opinion does not address the merits of the underlying decision by
the Company to engage in the Transaction and does not constitute a
recommendation to any shareholder of the Company as to how such shareholder
should vote on the proposed Transaction or any matter related thereto.

     We are not expressing any opinion herein as to the prices at which shares
of Company Common Stock will trade following the announcement or consummation of
the Transaction.

     On the basis of and subject to the foregoing, we are of the opinion that,
as of the date hereof, the Transaction is fair from a financial point of view to
the Company.

                                          Very truly yours,

                                          Merrill Lynch, Pierce Fenner & Smith
                                          Incorporated

        which Parent is a party, or any outstanding decree, order or judgment,
        which arose out of any proceeding to which Parent was either a party or
        of which Parent has knowledge, restricting in any manner the use,
        transfer, or licensing thereof by Parent, or which may affect the
        validity, use or enforceability of such Parent Intellectual Property.

             (b) Each material item of Parent Registered Intellectual Property

        licenses and related restrictions).

             (d) Neither Parent nor any of its subsidiaries has transferred

        marketing and sale of the products or services of Parent (including with
        respect to products currently under development) has not, does not and
        will not materially infringe or materially misappropriate the
        Intellectual Property of any third party or, to its knowledge,

        jurisdiction.

             (g) Parent has not received written notice from any third party
        that the operation of the business of Parent or any act, product or
        service of Parent, infringes or misappropriates the Intellectual
        Property of any third party or constitutes unfair competition or trade
        practices under the laws of any jurisdiction, which allegation, if true,
        would have a Material Adverse Effect on Parent.

        misappropriating any Parent Intellectual Property, which infringement or
        misappropriation, individually or in the aggregate, would have a
        Material Adverse Effect on Parent.

             (i) Parent and its subsidiaries have taken reasonable steps to
        protect Parent's and its subsidiaries' rights in Parent's and such
        subsidiaries' confidential information and trade secrets, except where
        the failure to do so would not have a Material Adverse Effect on Parent.

             (j) None of the Parent Intellectual Property or product or service
        of Parent contains any defect in connection with processing data
        containing dates in leap years or in the year 2000 or any preceding or

     (a) Neither Parent nor any of its subsidiaries is in conflict with, or in
default or in violation of (i) any law, rule, regulation, order, judgment or

of its subsidiaries or any of their respective properties is bound or affected,
or (ii) any note, bond, mortgage, indenture, agreement, lease, license, permit,
franchise or other instrument or obligation to which Parent or any of its
subsidiaries is a party or by which Parent or any of its subsidiaries or its or
any of their respective properties is bound or affected, except for conflicts,
violations and defaults that, individually or in the aggregate, would not have a
Material Adverse Effect on Parent. To Parent's knowledge, no investigation or
review by any Governmental Entity is pending or has been threatened in a writing
delivered to Parent against Parent or any of its subsidiaries. There is no
agreement with any Governmental Entity, judgment, injunction, order or decree
binding upon Parent or any of its subsidiaries which has or could reasonably be
expected to have the effect of prohibiting or materially impairing any material
business practice of Parent or any of its subsidiaries, or any acquisition of
material property by Parent or any of its subsidiaries.

     (b) Parent and its subsidiaries hold all permits, licenses, exemptions,
orders and approvals from governmental authorities that are material to or
required for the operation of the business of Parent as currently conducted
(collectively, the "PARENT PERMITS"), and are in compliance with the terms of
the Parent Permits, except where the failure to hold such Parent Permits, or be
in such compliance, would not, individually or in the aggregate, have a Material
Adverse Effect on Parent.

     3.11 Litigation.  There are no claims, suits, actions or proceedings
pending or, to the knowledge of Parent, threatened against, relating to or
affecting Parent or any of its subsidiaries, before any Governmental Entity or
any arbitrator that seeks to restrain or enjoin the consummation of the
transactions contemplated by this Agreement or which could reasonably be
expected, either singularly or in the aggregate with all such claims, actions or
proceedings, to have a Material Adverse Effect on Parent following the
transactions contemplated hereby or have a material adverse effect on the
ability of the parties hereto to consummate the transactions contemplated
hereby.

pending, or, to Parent's knowledge, threatened material claims or actions
against Parent under any worker's compensation policy or long-term disability

engaged in any unfair labor practices within the meaning of the National Labor

     (l) International Employee Plan.  Each International Parent Employee Plan
has been established, maintained and administered in material compliance with
its terms and conditions and with the requirements prescribed by any and all
statutory or regulatory laws that are applicable to such International Parent
Employee Plan. Furthermore, no International Parent Employee Plan has unfunded
liabilities, that as of the Closing, will not be offset by insurance or fully
accrued. Except as required by law, no condition exists that would prevent
Parent from terminating or amending any International Parent Employee Plan at
any time for any reason.

     3.13 Environmental Matters.  During the period that Parent has leased or
owned its properties or leased, owned or operated any facilities, there have
been no disposals, releases or threatened releases of Hazardous Materials (as
defined below) on, from or under any such properties or facilities that would
have a Material Adverse Effect on Parent. Parent has no knowledge of any
presence, disposals, releases or threatened releases of Hazardous Materials on,
from or under any of such properties or facilities, which may have occurred
prior to Parent or any of its subsidiaries having taken possession of any of
such properties or facilities which might reasonably be expected to have a
Material Adverse Effect on Parent. None of the properties or facilities
currently leased or owned by Parent or any of its subsidiaries or any properties
or facilities previously leased or owned by Parent or any of its subsidiaries is
in violation of any federal, state or local law, ordinance, regulation or order
relating to industrial hygiene or to the environmental conditions on, under or
about such properties or facilities, including, but not limited to, soil and
ground water condition which violation would have a Material Adverse Effect on
Parent. During Parent's occupancy of any properties or facilities owned or
leased at any time by Parent, neither Parent, nor to Parent's knowledge, any
third party, has used, generated, manufactured, released or stored on, under or
about such properties and facilities or transported to or from such properties
and facilities any Hazardous Materials that would have or is reasonably likely
to have a Material Adverse Effect on Parent. During the time that Parent or any
of its subsidiaries has owned or leased the properties and facilities currently
occupied by it or any properties and facilities previously occupied by Parent or
any of its subsidiaries, there has been no material litigation, proceeding or
administrative action brought or threatened against Parent or any of its
subsidiaries, or any material settlement reached by Parent or any of its
subsidiaries

                                      B-13
<PAGE>   60

with, any party or parties alleging the presence, disposal, release or
threatened release of any Hazardous Materials on, from or under any of such
properties or facilities.

"THREATENED RELEASE" have the definitions assigned thereto by the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, 42 U.S.C. sec.
9601 et seq., as amended ("CERCLA"). For the purposes of this Section 3.13,

     Parent or any of its subsidiaries on no more than thirty days notice

     subsidiaries' ability to terminate employees at will, or any consulting
     agreement;

     or any material instrument evidencing indebtedness for borrowed money by

with any Parent SEC Report ("PARENT CONTRACTS") are valid and in full force and
effect, except to the extent that such invalidity would not have a Material

authority, and all requisite qualifications to do business as a foreign entity,
to conduct its business in the manner in which its business is currently being

hereby and thereby have been duly authorized by all necessary action on the part
of VHA. This Agreement and the Outsourcing Agreement have each been duly
executed and delivered by VHA and constitute the valid and binding obligations
of VHA, enforceable against VHA in accordance with their terms, except as
enforceability may be limited by bankruptcy and other similar laws affecting the
rights of creditors generally and general principles of equity.

     (b) The execution and delivery of this Agreement and the Outsourcing
Agreement by VHA does not, and the performance of this Agreement and the
Outsourcing Agreement by VHA will not, (i) conflict with or violate the
certificate of incorporation, bylaws, operating agreement or other
organizational documents of VHA, (ii) subject to compliance with the
requirements set forth in Section 4.2(c) with regard to VHA, conflict with or
violate any law, rule, regulation, order, judgment or decree applicable to VHA
or by which any of its properties are bound or affected, or (iii) result in any
breach of or constitute a default (or an event that with notice or lapse of time
or both would become a default) under, or impair VHA's rights or alter the
rights or obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of an Encumbrance on any of the properties or assets of VHA pursuant
to, any note, bond, mortgage, indenture, contract, agreement, lease, license,
permit, franchise or other instrument or obligation to which VHA is a party or
by which VHA or any of its properties are bound or affected, except, in the case
of clauses (ii) and (iii), for such conflicts, violations, breaches, defaults,
impairments, or rights which, individually or in the aggregate, would not have a
Material Adverse Effect on VHA. Except as set forth in a letter delivered by VHA
to Parent concurrently with the execution of this Agreement, no consents,
waivers and approvals under any of VHA's or any of its subsidiaries' agreements,
contracts, licenses or leases are required to be obtained in connection with the
consummation of the transactions contemplated hereby, which, if individually or
in the aggregate not obtained, would have a Material Adverse Effect on VHA.

     (c) No consent, approval, order or authorization of, or registration,
declaration or filing with any Governmental Entity is required to be obtained or
made by VHA in connection with the execution and delivery of this Agreement or
the Outsourcing Agreement or the consummation of the transactions contemplated
hereby or thereby, except for (i) such consents, approvals, orders,
authorizations, registrations, declarations and filings as may be required under
applicable federal, foreign and state securities (or related) laws and the HSR
Act and the securities or antitrust laws of any foreign country, and (ii) such
other consents, authorizations, filings, approvals and registrations which if
not obtained or made would not have a Material Adverse Effect on VHA or have a
material adverse effect on the ability of the parties hereto to consummate the
transactions contemplated hereby.

     4.3 Acquisition for Own Account.  The Shares, Warrant and Warrant Stock to
be delivered to VHA hereunder will be acquired for VHA's own account, not as a
nominee or agent, and not with a view to the public resale or distribution
thereof within the meaning of the 1933 Act, and VHA represents that it has no
present intention or agreement to sell, grant any participation in, or otherwise
distribute any of the Shares, Warrant or Warrant Stock to be acquired by VHA
hereunder in any public resale or distribution within the meaning of the 1933
Act. VHA also represents that it has not been formed for the specific purpose of
acquiring the Shares, Warrant or Warrant Stock under this Agreement.

     4.4 Disclosure of Information.  VHA believes it has received or has had
full access to all the information it considers necessary or appropriate to make
an informed ownership decision with respect to the Shares, Warrant and Warrant
Stock to be issued to VHA under this Agreement. VHA further has had an
                                      B-16
<PAGE>   63

opportunity to ask questions and receive answers from Parent regarding the terms
and conditions of the offering of the Shares, Warrant and Warrant Stock and to
obtain additional information (to the extent Parent possessed such information
or could acquire it without unreasonable effort or expense) necessary to verify
any information furnished to VHA or to which VHA had access. The foregoing,
however, does not in any way limit or modify the representations and warranties
made by Parent in Section 3.

     4.5 Experience.  VHA understands that ownership of the Shares, Warrant and
Warrant Stock involves substantial risk. VHA: (i) has experience as owner of
securities of companies in the development stage and acknowledges that VHA is
able to fend for itself, can bear the economic risk of VHA's ownership of the
Shares, Warrant and Warrant Stock and has such knowledge and experience in
financial or business matters that VHA is capable of evaluating the merits and
risks of this ownership of the Shares, Warrant and Warrant Stock and protecting
its own interests in connection with this ownership and/or (ii) has a
preexisting personal or business relationship with Parent and certain of its
officers, directors or controlling persons of a nature and duration that enables
VHA to be aware of the character, business acumen and financial circumstances of
such persons.

     4.6 Accredited Investor Status.  VHA is an "accredited investor" within the
meaning of Regulation D promulgated under the 1933 Act.

     4.7 Restricted Securities.  VHA understands that the Shares and the Warrant
are, and upon issuance under the Warrant, the Warrant Stock will be
characterized as "restricted securities" under the 1933 Act inasmuch as they are
being acquired from Parent in a transaction not involving a public offering and
that under the 1933 Act and applicable regulations thereunder such securities
may be resold without registration under the 1933 Act only in certain limited
circumstances. In this connection, VHA represents that VHA is familiar with Rule
144 of the SEC, as presently in effect, and understands the resale limitations
imposed thereby and by the 1933 Act.

     4.8 No Solicitation.  At no time was VHA presented with or solicited by any
publicly issued or circulated newspaper, mail, radio, television or other form
of general advertising or solicitation in connection with the issuance or
delivery of the Shares or the Warrant.

     4.9 Further Limitations on Disposition.  Without in any way limiting the
representations set forth above, VHA further agrees not to make any disposition
of all or any portion of the Shares or Warrant Stock or of any interest therein
to any person or entity unless:

          (a) there is then in effect a registration statement under the 1933
     Act covering such proposed disposition of Shares or Warrant Stock and such
     disposition is made in accordance with such registration statement; or

          (b) VHA shall have notified Parent of the proposed disposition of the
     Shares or the Warrant Stock and shall have furnished Parent with a
     statement of the circumstances surrounding such proposed disposition, and,
     at the expense of VHA or its transferee, with an opinion of counsel,
     reasonably satisfactory to Parent, that such disposition will not require
     registration of such securities under the 1933 Act.

VHA acknowledges that the Warrant is non-transferable to the extent it has not
vested.

     4.10 Legends.  VHA understands and agrees that the certificates evidencing
the Shares, the Warrant and the Warrant Stock will bear legends substantially
similar to those set forth below, as applicable, in addition to any other legend
that may be required by applicable law, by Parent's Certificate of Incorporation
or Bylaws, or by any agreement between Parent and VHA:

          (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES
     LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON
     TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS
     PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT
     TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE
                                      B-17
<PAGE>   64

     AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS
     INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES
     MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE
     ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OTHERWISE PERMITTED UNDER
     CONTRACTUAL RESTRICTIONS ON RESALE APPLICABLE TO THESE SECURITIES IS IN
     COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

          (b) THE SECURITIES REPRESENTED HEREBY MAY BE SUBJECT TO CERTAIN
     RESTRICTIONS ON RESALE AND ON VOTING AND THE HOLDERS HEREOF MAY BE BOUND BY
     CERTAIN RESTRICTIONS ON ACQUISITION OF THE ISSUER'S CAPITAL STOCK PURSUANT
     TO A COMMON STOCK AND WARRANT AGREEMENT BETWEEN THE ORIGINAL HOLDERS OF
     THESE SECURITIES AND THE ISSUER, A COPY OF WHICH MAY BE OBTAINED FROM THE
     ISSUER.

The legend set forth in (a) above shall be removed by Parent from any
certificate evidencing Shares or Warrant Stock upon delivery to Parent of an
opinion by counsel, reasonably satisfactory to Parent, to the effect that a
registration statement under the 1933 Act is at that time in effect with respect
to the legended security or to the effect that such security can be freely
transferred in a public sale without such a registration statement being in
effect and that such transfer will not jeopardize the exemption or exemptions
from registration pursuant to which Parent issued the Shares or Warrant Stock.

     4.11 Disclosure.  The information supplied by VHA for inclusion or
incorporation by reference in the Proxy Statement shall not on the date the
Proxy Statement is mailed to Parent's stockholders, at the time of the Parent
Stockholders' Meeting or as of the Closing, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not false or misleading; or omit to
state any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of proxies for the Parent
Stockholders' Meeting which has become false or misleading. If at any time prior
to the Closing any event relating to VHA or any of its affiliates, officers or
directors should be discovered by VHA which is required to be set forth in a
supplement to the Proxy Statement, VHA shall promptly inform Parent.
Notwithstanding the foregoing, VHA makes no representation or warranty with
respect to any information supplied by Parent which is contained in the Proxy
Statement.

     4.12 Anti-Takeover Protections.  For the three years prior to the date of
this Agreement, none of VHA, its "affiliates" nor "associates" (as such terms
are defined in Section 203 of the Delaware Law) were the owner of 15% or more of
the outstanding voting stock of Parent. To VHA's knowledge, no other Takeover
Statute applies or purports to apply to this Agreement or the transactions
contemplated hereby.

                                   ARTICLE V

                          CONDUCT PRIOR TO THE CLOSING

     5.1 Conduct of Business by Parent.  During the period from the date of this
Agreement and continuing until the earlier of the termination of this Agreement
pursuant to its terms or the Closing, Parent and each of its subsidiaries shall,
except to the extent that VHA shall otherwise consent in writing, carry on its
business in compliance in all material respects with all applicable material
laws and regulations, pay its debts and taxes when due subject to good faith
disputes over such debts or taxes, pay or perform other material obligations
when due, and use its commercially reasonable efforts consistent with past
practices and policies to (i) preserve intact its present business organization,
(ii) keep available the services of its present officers and employees and (iii)
preserve its relationships with customers, suppliers, licensors, licensees, and
others with which it has business dealings. In addition, Parent will promptly
notify VHA of any material adverse event involving its business or operations.

     In addition, except as permitted by the terms of this Agreement, and except
as contemplated by this Agreement or provided in the Parent Disclosure Letter,
without the prior written consent of VHA, during the period from the date of
this Agreement and continuing until the earlier of the termination of this
Agreement
                                      B-18

pursuant to its terms or the Closing, Parent shall not do any of the following
and shall not permit its subsidiaries to do any of the following:

          (a) Waive any stock repurchase rights, accelerate, amend or change the
     period of exercisability of options or restricted stock, or reprice options
     granted under any employee, consultant, director or other stock plans or
     authorize cash payments in exchange for any options granted under any of
     such plans;

          (b) Grant any severance or termination pay to any officer or employee

     new severance plan;

          (c) Transfer or license to any person or entity or otherwise extend,
     amend or modify in any material respect any rights to any Intellectual
     Property material to the business of Parent that is owned by, or
     exclusively licensed to, Parent or one of its subsidiaries, other than
     non-exclusive licenses, distribution agreements, advertising agreements, or
     other similar agreements in the ordinary course of business and consistent
     with past practice;

          (d) Declare, set aside or pay any dividends on or make any other
     distributions (whether in cash, stock, equity securities or property) in
     respect of any capital stock or split, combine or reclassify any capital
     stock or issue or authorize the issuance of any other securities in respect
     of, in lieu of or in substitution for any capital stock;

          (e) Purchase, redeem or otherwise acquire, directly or indirectly, any
     shares of capital stock of Parent or its subsidiaries, except repurchases
     of unvested shares at cost in connection with the termination of the
     employment relationship with any employee pursuant to stock option or
     purchase agreements in effect on the date hereof;

          (f) Issue, deliver, sell, authorize, pledge or otherwise encumber any
     shares of capital stock or any securities convertible into shares of
     capital stock, or subscriptions, rights, warrants or options to acquire any
     shares of capital stock or any securities convertible into shares of
     capital stock, or enter into other agreements or commitments of any
     character obligating it to issue any such shares or convertible securities,
     other than the grant, issuance, delivery and/or sale of (i) shares of
     Common Stock pursuant to the exercise of Parent Options outstanding on the
     date of this Agreement, or granted in accordance with clause (iii) of this
     Section 5.1(f), (ii) shares of Common Stock issuable to participants in the
     Parent ESPP consistent with the terms thereof, (iii) Parent Options granted
     to existing employees and newly-hired employees in an aggregate amount not
     to exceed 2,000,000, none of which Parent Options shall provide for or
     permit any acceleration of the exercisability thereof in connection with
     any of the transactions contemplated by this Agreement, and (iv) shares of
     Common Stock issued in connection with acquisitions, joint ventures,
     strategic relationships or alliances, and commercial transactions permitted
     under Section 5.1(h) below;

          (g) Cause, permit or propose any amendments to its Certificate of
     Incorporation, Bylaws or other charter documents (or similar governing
     instruments of any of its subsidiaries), other than an amendment to its
     Certificate of Incorporation to increase the authorized number of shares of
     Common Stock;

          (h) Acquire or agree to acquire by merging or consolidating with, or
     by purchasing any equity interest in or a portion of the assets of, or by
     any other manner, any business or any corporation, partnership, association
     or other business organization or division thereof; or otherwise acquire or
     agree to acquire any assets which are material, individually or in the
     aggregate, to the business of Parent, or enter into any material joint
     ventures, strategic relationships or alliances, or enter into any
     commercial transaction involving the issuance or potential issuance of
     equity securities of Parent; provided, that Parent shall not be prohibited
     hereunder from (x) acquiring EquipMD, Inc. pursuant to the Agreement and
     Plan of Merger among Parent, Augustacorp, Inc. and EquipMD, Inc. (a true
     and complete copy of which has been made available to VHA) or (y) making or
     agreeing to make acquisitions, entering into joint ventures, strategic
     relationships or alliances, or entering into commercial transactions
     involving the issuance or potential issuance of Common Stock, all of which
     together do not involve the issuance or potential issuance of more than
     5,000,000 shares of Common Stock in the aggregate, and none of which
                                      B-19
<PAGE>   66

     acquisitions, joint ventures, strategic relationships, alliances,
     agreements or commercial transactions could reasonably be expected to
     materially delay the issuances of Common Stock and Warrant contemplated by
     this Agreement (Parent and VHA acknowledge that the fact that an
     acquisition would be deemed "significant" under Item 2 of Form 8-K under
     the 1934 Act does not necessarily mean that such acquisition could
     reasonably be expected to materially delay the issuances of Common Stock
     and the Warrant contemplated by this Agreement); provided, further, that
     Parent shall provide written notice to VHA prior to signing any agreement
     regarding any such acquisition or transaction;

          (i) Sell, lease, license, encumber (except in connection with actions
     permitted under Section 5.1(j)) or otherwise dispose of any properties or
     assets which are material, individually or in the aggregate, to the
     business of Parent;

          (j) Incur any indebtedness for borrowed money or guarantee any such
     indebtedness of another person, issue or sell any debt securities or
     options, warrants, calls or other rights to acquire any debt securities of
     Parent, enter into any "keep well" or other agreement to maintain any
     financial statement condition or enter into any arrangement having the
     economic effect of any of the foregoing other than (i) in connection with
     the financing of ordinary course trade payables consistent with past
     practice, (ii) pursuant to existing credit facilities in the ordinary
     course of business, (iii) equipment leasing arrangements or (iv) in
     aggregate amount not to exceed $1,000,000;

          (k) (i) Adopt or amend any employee benefit plan or employee stock
     purchase or employee stock option plan, or enter into any employment
     contract or collective bargaining agreement (other than offer letters and
     letter agreements entered into in the ordinary course of business
     consistent with past practice with employees who are terminable "at will")
     other than an increase in the number of shares of Common Stock reserved for
     issuance under Parent Stock Option Plans or Parent ESPP, or (ii) pay any
     special bonus or special remuneration to any director or employee, or
     increase the salaries or wage rates or fringe benefits (including rights to
     severance or indemnification) of its directors, officers, employees or
     consultants other than in the ordinary course of business, consistent with
     past practice, or change in any material respect any management policies or
     procedures;

          (l) Make any capital expenditures outside of the ordinary course of
     business or any capital expenditures in excess of $1,000,000, individually,
     or $10,000,000, in the aggregate;

          (m) Materially modify, amend or terminate any material contract or
     agreement to which Parent or any subsidiary thereof is a party, or waive,
     release or assign any material rights or claims thereunder, except in the
     ordinary course of business;

          (n) Materially revalue any of its assets or, except as required by
     GAAP, make any change in accounting methods, principles or practices;

          (o) Initiate or settle any material litigation, arbitration, mediation
     or other legal proceeding;

          (p) Take or permit any action with the intent to directly or
     indirectly adversely impact any of the transactions contemplated by this
     Agreement; or

          (q) Agree in writing or otherwise to take any of the actions described
     in Section 5.1 (a) through (p) above.

     5.2 Meeting of Parent Stockholders.

     (a) Promptly after the date hereof, Parent will take all action necessary
in accordance with the Delaware Law and its Certificate of Incorporation and
Bylaws to convene the Parent Stockholders' Meeting to be held as promptly as
practicable and in any event (to the extent permissible under applicable law)
within 45 days after the completion of the SEC's review of the Proxy Statement
for the purpose of voting upon the Parent Stockholder Approval. Subject to
Section 5.2(c), Parent will use its commercially reasonable efforts to solicit
from its stockholders proxies in favor of the approval of the Parent Stockholder
Approval and will take all other action necessary or advisable to secure the
vote or consent of its stockholders required by the rules of the Nasdaq Stock
Market, Delaware Law, its Certificate of Incorporation and Bylaws to obtain such
approval.

                                      B-20
<PAGE>   67

Notwithstanding anything to the contrary contained in this Agreement, Parent may
adjourn or postpone the Parent Stockholders' Meeting to the extent necessary to
ensure that any necessary supplement or amendment to the Proxy Statement is
provided to Parent's stockholders in advance of a vote on the Parent Stockholder
Approval or, if as of the time for which Parent Stockholders' Meeting is
originally scheduled (as set forth in the Proxy Statement) there are
insufficient shares of Parent Common Stock represented (either in person or by
proxy) to constitute a quorum necessary to conduct the business of the Parent
Stockholders' Meeting. Parent shall ensure that the Parent Stockholders' Meeting
is called, noticed, convened, held and conducted, and that all proxies solicited
by Parent in connection with the Parent Stockholders' Meeting are solicited, in
compliance with the Delaware Law, its Certificate of Incorporation and Bylaws,
the rules of the Nasdaq Stock Market and all other applicable legal
requirements.

     (b) Subject to Section 5.2(c), the Board of Directors of Parent shall
recommend that Parent's stockholders approve the Parent Stockholder Approval at
the Parent Stockholders' Meeting; and the Proxy Statement shall include a
statement to the effect that the Board of Directors of Parent has recommended
that Parent's stockholders approve the Parent Stockholder Approval at the Parent
Stockholders' Meeting; and (iii) neither the Board of Directors of Parent nor
any committee thereof shall withdraw, amend or modify, or propose or resolve to
withdraw, amend or modify in a manner adverse to VHA, the recommendation of the
Board of Directors of Parent that Parent's stockholders approve the Parent
Stockholder Approval.

     (c) Nothing in this Agreement shall prevent the Board of Directors of
Parent from withholding, withdrawing, amending or modifying its recommendation
in favor of the Parent Stockholder Approval if (i) a Superior Offer (as defined
below) is made to Parent and is not withdrawn, (ii) Parent shall have provided
written notice to VHA and UHC (a "NOTICE OF SUPERIOR OFFER") advising them that
Parent has received a Superior Offer, specifying all of the material terms and
conditions of such Superior Offer and identifying the person or entity making
such Superior Offer, (iii) VHA and/or UHC shall not have, within three business
days of Parent's receipt of the Notice of Superior Offer, made an offer that
Parent's Board of Directors by a majority vote determines in its good faith
judgment (after consultation with a financial advisor of national standing) to
be at least as favorable to Parent's stockholders as such Superior Offer (it
being agreed that the Board of Directors of Parent shall convene a meeting to
consider any such offer by VHA and/or UHC promptly following the receipt
thereof), (iv) the Board of Directors of Parent concludes in good faith, after
consultation with its outside counsel, that, in light of such Superior Offer,
the withholding, withdrawal, amendment or modification of such recommendation is
required in order for the Board of Directors of Parent to comply with its
fiduciary obligations to Parent's stockholders under applicable law and (v)
Parent shall not have violated any of the restrictions set forth in Section
5.4(a) or (b) or this Section 5.2. Parent shall provide VHA with at least one
day prior notice (or such lesser prior notice as provided to the members of the
Parent's Board of Directors) of any meeting of the Parent's Board of Directors
at which Parent's Board of Directors is reasonably expected to consider any
Parent Acquisition Proposal (as defined in Section 5.4) to determine whether
such Parent Acquisition Proposal is a Superior Offer. Nothing contained in this
Section 5.2(c) shall limit Parent's obligation to hold and convene the Parent
Stockholders' Meeting (regardless of whether the recommendation of the Board of
Directors of Parent shall have been withdrawn, amended or modified).

     For purposes of this Agreement, "SUPERIOR OFFER" shall mean an unsolicited,
bona fide written offer made by a third party to consummate any of the following
transactions: (i) a merger or consolidation involving Parent pursuant to which
the stockholders of Parent immediately preceding such transaction hold less than
50% of the equity interest in the surviving or resulting entity of such
transaction or (ii) the acquisition by any person or group (including by way of
a tender offer or an exchange offer or a two step transaction involving a tender
offer followed with reasonable promptness by a merger involving Parent),
directly or indirectly, of ownership of 100% of the then outstanding shares of
capital stock of Parent, on terms that the Board of Directors of Parent
determines, in its reasonable judgment (after consultation with a financial
advisor of national standing) to be more favorable to Parent stockholders than
the terms of this Agreement and the UHC Agreement; provided, however, that any
such offer shall not be deemed to be a "Superior Offer" if any financing
required to consummate the transaction contemplated by such offer is not
committed and is not likely in the reasonable judgment of Parent's Board of
Directors (after consultation with its financial advisor) to be obtained by such
third party on a timely basis.

                                      B-21
<PAGE>   68

     (d) Nothing contained in this Agreement shall prohibit Parent or its Board
of Directors from taking and disclosing to its stockholders a position
contemplated by Rules 14d-9 and 14e-2(a) promulgated under the 1934 Act, or
otherwise required by applicable law.

     5.3 Proxy Statement; Antitrust Filings.

     (a) As promptly as practicable after the execution of this Agreement,
Parent will prepare and file with the SEC, the Proxy Statement. Parent will
respond to any comments of the SEC, and will cause the Proxy Statement to be
mailed to its stockholders, as promptly as practicable in compliance with
applicable law. Promptly after the date of this Agreement, each of VHA and
Parent will prepare and file (i) with the United States Federal Trade Commission
and the Antitrust Division of the United States Department of Justice
Notification and Report Forms relating to the transactions contemplated herein
as required by the HSR Act, as well as comparable pre-merger notification forms
required by the merger notification or control laws and regulations of any
applicable jurisdiction, as agreed to by the parties (the "ANTITRUST FILINGS").
VHA and Parent each shall promptly supply the other with any information which
may be required in order to effectuate any filings pursuant to this Section 5.3.

     (b) Each of VHA and Parent will notify the other promptly upon the receipt
of any comments from the SEC or its staff or any other government officials in
connection with any filing made pursuant hereto and of any request by the SEC or
its staff or any other government officials for amendments or supplements to the
Proxy Statement or any Antitrust Filings or for additional information, and will
supply the other with copies of all correspondence between such party or any of
its representatives, on the one hand, and the SEC, or its staff or any other
government officials, on the other hand, with respect to the Proxy Statement or
any Antitrust Filing. Each of VHA and Parent will cause all documents that it is
responsible for filing with the SEC or other regulatory authorities under this
Section 5.3 to comply in all material respects with all applicable requirements
of law and the rules and regulations promulgated thereunder. Whenever any event
occurs which is required to be set forth in an amendment or supplement to the
Proxy Statement or any Antitrust Filing, VHA or Parent, as the case may be, will
promptly inform the other of such occurrence and cooperate in filing with the
SEC or its staff or any other government officials, and/or mailing to
stockholders of Parent, such amendment or supplement.

     5.4 No Solicitation.

     (a) From and after the date of this Agreement until the Closing or
termination of this Agreement pursuant to Article IX, Parent and its
subsidiaries will not, nor will they authorize or permit any of their respective
officers, directors, affiliates or employees or any investment banker, attorney
or other advisor or representative retained by any of them to, directly or
indirectly, (i) solicit, initiate, encourage or induce the making, submission or
announcement of any Parent Acquisition Proposal (as hereinafter defined), (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any non-public information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes an
Parent Acquisition Proposal, (iii) engage in discussions with any person with
respect to any Parent Acquisition Proposal, except as to the existence of these
provisions, (iv) except as set forth in Section 5.2(c), approve, endorse or
recommend any Parent Acquisition Proposal or (v) enter into any letter of intent
or similar document or any contract, agreement or commitment contemplating or
otherwise relating to any Parent Acquisition Proposal; provided, however, that
prior to the approval of the Parent Stockholder Approval at the Parent
Stockholders' Meeting, Parent may furnish nonpublic information regarding Parent
and its subsidiaries to, or enter into discussions or negotiations with, any
person or group who has submitted (and not withdrawn) to Parent an unsolicited,
written, bona fide Parent Acquisition Proposal that the Board of Directors of
Parent reasonably concludes (after consultation with a financial advisor of
national standing) may constitute a Superior Offer if (1) neither Parent nor any
representative of Parent and its subsidiaries shall have violated any of the
restrictions set forth in this Section 5.4, (2) the Board of Directors of Parent
concludes in good faith, after consultation with its outside legal counsel, that
such action is required in order for the Board of Directors of Parent to comply
with its fiduciary obligations to Parent's stockholders under applicable law,
(3) 36 hours prior to furnishing any such nonpublic information to, or entering
into any such discussions with, such person or group, Parent gives VHA and UHC
written notice of the identity of such person or group and

                                      B-22
<PAGE>   69

all of the material terms and conditions of such Parent Acquisition Proposal and
of Parent's intention to furnish nonpublic information to, or enter into
discussions with, such person or group, and Parent receives from such person or
group an executed confidentiality agreement containing customary terms. Parent
and its subsidiaries will immediately cease any and all existing activities,
discussions or negotiations with any parties conducted heretofore with respect
to any Parent Acquisition Proposal. Without limiting the foregoing, it is
understood that any violation of the restrictions set forth in the preceding two
sentences by any officer, director or employee of Parent or any of its
subsidiaries or any investment banker, attorney or other advisor or
representative of Parent or any of its subsidiaries shall be deemed to be a
breach of this Section 5.4(a) by Parent.

     For purposes of this Agreement, "PARENT ACQUISITION PROPOSAL" shall mean
any offer or proposal relating to any transaction or series of related
transactions, other than the transactions contemplated by this Agreement (any
such transaction or series of related transactions, a "PARENT ACQUISITION"),
involving: (A) any acquisition or purchase from Parent by any person or "group"
(as defined under Section 13(d) of the 1934 Act and the rules and regulations
thereunder) of more than 50% of the outstanding voting securities of Parent or
any of its subsidiaries, or any tender offer or exchange offer that if
consummated would result in any person or "group" beneficially owning more than
50% of the outstanding voting securities of Parent or any of its subsidiaries,
or any merger, consolidation, business combination or similar transaction
involving Parent pursuant to which the stockholders of Parent immediately
preceding such transaction hold less than 50% of the equity interests in the
surviving or resulting entity of such transaction; or (B) any sale, exchange,
transfer, acquisition, or disposition of more than 50% of the assets of Parent.

     (b) In addition to the obligations of Parent set forth in paragraph (a) of
this Section 5.4, Parent as promptly as practicable shall advise VHA and UHC
orally and in writing of any request for non-public information or inquiry which
Parent reasonably believes would lead to a Parent Acquisition Proposal or of any
Parent Acquisition Proposal, the material terms and conditions of such request,
Parent Acquisition Proposal or inquiry, and the identity of the person or group
making any such request, Parent Acquisition Proposal or inquiry. Parent will
keep VHA and UHC informed as promptly as practicable in all material respects of
the status and details (including material amendments or proposed amendments) of
any such request, Parent Acquisition Proposal or inquiry.

     (c) From and after the date of this Agreement until the Closing or
termination of this Agreement pursuant to Article IX, VHA and its affiliates
will not, nor will they authorize or permit any of their respective officers,
directors, affiliates or employees or any investment banker, attorney or other
advisor or representative retained by any of them to, directly or indirectly,
(i) solicit, initiate, encourage or induce the making, submission or
announcement of any VHA Proposal (as hereinafter defined), (ii) participate in
any discussions or negotiations regarding, or furnish to any person any
non-public information with respect to, or take any other action to facilitate
any inquiries or the making of any proposal that constitutes a VHA Proposal,
(iii) engage in discussions with any person with respect to any VHA Proposal,
except as to the existence of these provisions, (iv) approve, endorse or
recommend any VHA Proposal or (v) enter into any letter of intent or similar
document or any contract, agreement or commitment contemplating or otherwise
relating to any VHA Proposal. VHA and its affiliates will immediately cease any
and all existing activities, discussions or negotiations with any parties
conducted heretofore with respect to any VHA Proposal. Without limiting the
foregoing, it is understood that any violation of the restrictions set forth in
the preceding two sentences by any officer, director or employee of VHA or any
of its affiliates or any investment banker, attorney or other advisor or
representative of VHA or any of its affiliates shall be deemed to be a breach of
this Section 5.4(c) by VHA. For purposes of this Agreement, "VHA PROPOSAL" shall
mean any offer or proposal relating to any transaction or series of related
transactions that would constitute a breach or violation of, the obligations
(including exclusivity obligations) of VHA, UHC, Novation and/or HPPI under the
Outsourcing Agreement.

     (d) In addition to the obligations of VHA set forth in paragraph (c) of
this Section 5.4, VHA as promptly as practicable shall advise Parent orally and
in writing of any request for non-public information or inquiry which VHA
reasonably believes would lead to a VHA Proposal or of any VHA Proposal, the
material terms and conditions of such request, VHA Proposal or inquiry, and the
identity of the person or group making any such request, VHA Proposal or
inquiry. VHA will keep Parent informed as promptly as practicable in all
                                      B-23
<PAGE>   70

material respects of the status and details (including material amendments or
proposed amendments) of any such request, VHA Proposal or inquiry.

     5.5 Third Party Consents.  As soon as practicable following the date
hereof, Parent and VHA will each use its commercially reasonable efforts to
obtain any material consents, waivers and approvals under any of its or its
subsidiaries' respective agreements, contracts, licenses or leases required to
be obtained in connection with the consummation of the transactions contemplated
hereby.

     5.6 Nasdaq Listing.  Parent agrees to authorize for listing on the Nasdaq
Stock Market the Shares and Warrant Stock issuable in connection with this
Agreement, effective upon official notice of issuance.

     5.7 Takeover Statutes.  If any Takeover Statute is or may become applicable
to the transactions contemplated by this Agreement, each of Parent and VHA and
their respective Boards of Directors shall grant such approvals and take such
lawful actions as are necessary to ensure that such transactions may be
consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise act to eliminate or minimize the effects of such
Takeover Statute and any regulations promulgated thereunder on such
transactions.

                                   ARTICLE VI

                             ADDITIONAL AGREEMENTS

     6.1 Voting of Common Stock.  VHA agrees that from and after the date of the
Closing through the fifth anniversary of the Closing (the "FIFTH ANNIVERSARY"),
and for as long after the Fifth Anniversary as the outstanding shares of Common
Stock (including outstanding Common Stock that has been issued pursuant to the
Warrant) beneficially owned by VHA together with all "affiliates" (which for
purposes of this Agreement (other than Section 3.12) shall have the meaning
given such term in Rule 144(a)(1) promulgated under the 1933 Act) of VHA exceeds
35% of the then outstanding Common Stock of Parent (the entire such period, the
"RESTRICTED PERIOD"), to the extent that the outstanding shares of Common Stock
(including outstanding Common Stock that has been issued pursuant to the
Warrant) beneficially owned by VHA together with all affiliates of VHA exceeds
19.9% of the then outstanding Common Stock of Parent (the shares in excess of
such 19.9% threshold, "EXCESS SHARES"), VHA shall, and shall cause its
affiliates to, vote all Excess Shares it holds or is entitled to vote in
proportion to the votes cast by all other stockholders of Parent in connection
with each matter submitted to Parent's stockholders for approval except for (i)
a proposed Change of Control, (ii) the election of VHA's designated nominees to
the Board of Directors of Parent, or (iii) an amendment of the Certificate of
Incorporation of Parent that would materially and adversely affect VHA as a
Parent stockholder in a manner different from the effect such amendment would
have on other Parent stockholders generally. On all matters submitted to Parent
stockholders for approval other than those identified in items (i), (ii) and
(iii) of the first sentence of this section, VHA shall, and shall cause its
affiliates to, vote all Excess Shares in proportion to the votes cast by all
other stockholders of Parent in connection with each matter submitted to Parent
stockholders' for approval, including, without limitation, on any matters
regarding equity-based or other compensation plans of Parent, the issuance of
capital stock of Parent, amendments to the Certificate of Incorporation of
Parent other than as set forth in clause (iii) above, elections of directors
other than VHA's designated nominees to the Board of Directors, or transactions
involving interested or related parties. Notwithstanding any voting restrictions
set forth herein, the Board of Directors of Parent may waive any voting
restriction set forth herein with respect to any particular matter. For purposes
of this Agreement, "CHANGE OF CONTROL" means the consummation of any transaction
or series of related transactions, including an acquisition of Parent by another
entity and any reorganization, merger, consolidation or share exchange, that
results in the beneficial owners of Parent's capital stock immediately prior to
the transaction or transactions holding less than 50% of the voting power of
Parent immediately after the transaction or transactions, or a transaction or
series of related transactions which result in the sale, exchange, transfer,
acquisition or disposition of more than 50% of the assets of Parent.

     6.2 Acquisition of Parent Securities.  VHA agrees that during the
Restricted Period, (i) at any time that VHA together with all of its affiliates
beneficially owns 24% (on a Common Stock-equivalent basis) or more

                                      B-24
<PAGE>   71

of the outstanding shares of Common Stock or other capital stock of Parent or of
any option, warrant or right to acquire capital stock of Parent (such shares,
options, warrants and other rights, collectively, "RIGHTS IN PARENT STOCK"), VHA
will not, without the prior written consent of Parent, acquire legal or
beneficial ownership of any additional Rights in Parent Stock, except pursuant
to the Warrant, and (ii) at any time that VHA, together with all of its
affiliates beneficially owns less than 24% of the outstanding Rights in Parent
Stock, VHA may acquire such number of Rights in Parent Stock so that after the
acquisition of such Rights in Parent Stock the aggregate number of Rights in
Parent Stock, on a Common Stock-equivalent basis, legally or beneficially owned
by VHA and all affiliates of VHA, assuming issuance of all shares of Parent
Common Stock issuable pursuant to such Rights in Parent Stock, equals not more
than 24% of the outstanding Common Stock of Parent.

     6.3 Transfer of Parent Securities.  VHA agrees that it will not, directly
or indirectly, in a single transaction or series of related transactions,
without the prior written consent of Parent, sell, transfer or otherwise dispose
of legal or beneficial ownership of Rights in Parent Stock to any person if such
person together with its affiliates would, to the knowledge of VHA, after
reasonable inquiry, beneficially own 15% or more of the then outstanding Rights
in Parent Stock, unless prior to such sale, transfer or disposal, such
transferee agrees in writing to be bound by VHA's agreements set forth in
Section 6.1, 6.2 (with "19.9%" in Section 6.1 and "24%" in Section 6.2 each read
as "15%") and this Section 6.3.

     6.4 Parent Board of Directors.  The Board of Directors of Parent will take
all actions reasonably necessary such that as soon as practicable following the
Closing, the size of Parent's Board of Directors shall be seven members, and two
persons shall be appointed by VHA to Parent's Board of Directors to fill
vacancies in Class I. Under the Parent's Charter Documents, the terms of Class I
Directors expire in 2000, the terms of Class II Directors expire in 2001 and the
terms of Class III Directors expire in 2002. The Class I Directors appointed
pursuant to this Section shall be appointed following Parent's annual meeting in
2000 to terms expiring in 2003. For so long as VHA beneficially owns 10% or more
of the outstanding Common Stock of Parent on a fully converted basis (taking
into account for VHA, all shares of Common Stock issuable upon the exercise of
the Warrant), Parent will take all actions reasonably necessary to have one
person appointed by VHA be a member of Parent's Board of Directors. For so long
as VHA beneficially owns 20% or more of the Common Stock of Parent on a fully
converted basis (taking into account for VHA, all shares of Common Stock
issuable upon the exercise of the Warrant), Parent will take all actions
reasonably necessary to have two persons appointed by VHA be members of Parent's
Board of Directors. If Parent's Board of Directors establishes an executive
committee or another committee of less than all directors having general
authority similar to that customarily delegated to an executive committee, one
member of such committee shall be a director nominated by VHA.

     6.5 Reasonable Efforts.

     (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use all reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other party in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the transactions contemplated by this Agreement, including using
reasonable efforts to accomplish the following: (i) the taking of all reasonable
acts necessary to cause the conditions precedent set forth in Articles VII and
VIII to be satisfied, (ii) the obtaining of all necessary actions or nonactions,
waivers, consents, approvals, orders and authorizations from Governmental
Entities and the making of all necessary registrations, declarations and filings
(including registrations, declarations and filings with Governmental Entities,
if any) and the taking of all reasonable steps as may be necessary to avoid any
suit, claim, action, investigation or proceeding by any Governmental Entity,
(iii) the obtaining of all necessary consents, approvals or waivers from third
parties, (iv) the defending of any suits, claims, actions, investigations or
proceedings, whether judicial or administrative, challenging this Agreement or
the consummation of the transactions contemplated hereby, including seeking to
have any stay or temporary restraining order entered by any court or other
Governmental Entity vacated or reversed and (v) the execution or delivery of any
additional instruments necessary to consummate the transactions contemplated by,
and to fully carry out the purposes of, this Agreement. Notwithstanding anything
in this Agreement to the contrary, neither Parent nor any of its affiliates
shall be under any obligation to make
                                      B-25
<PAGE>   72

proposals, execute or carry out agreements or submit to orders providing for the
sale or other disposition or holding separate (through the establishment of a
trust or otherwise) of any assets or categories of assets of Parent or any of
its affiliates or imposing or seeking to impose any limitation on the ability of
Parent or any of its subsidiaries or affiliates to conduct their business or own
such assets.

     (b) Each of VHA and Parent will give prompt notice to the other of (i) any
notice or other communication from any person alleging that the consent of such
person is or may be required in connection with the consummation of transactions
contemplated by this Agreement, (ii) any notice or other communication from any
Governmental Entity in connection with the transactions contemplated by this
Agreement or the Outsourcing Agreement, (iii) any litigation relating to,
involving or otherwise affecting VHA, Novation, HPPI, Parent or their respective
subsidiaries that relates to the consummation of the transactions contemplated
by this Agreement or the Outsourcing Agreement. VHA shall give prompt notice to
Parent of any representation or warranty made by it contained in this Agreement
becoming untrue or inaccurate, or any failure of VHA to comply with or satisfy
in any material respect any covenant, condition or agreement to be complied with
or satisfied by it under this Agreement, in each case, such that the conditions
set forth in Article VIII would not be satisfied, provided, however, that no
such notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement. Parent shall give prompt notice to VHA of any
representation or warranty made by it contained in this Agreement becoming
untrue or inaccurate, or any failure of Parent to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement, in each case, such that the conditions set
forth in Article VII would not be satisfied, provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.

     6.6 Registration Rights.  Parent shall use its reasonable best efforts to
cause the requisite holders of registration rights under the Second Amended and
Restated Registration Rights Agreement among Parent and certain of its investors
dated October 14, 1999 (the "EXISTING REGISTRATION RIGHTS AGREEMENT") to amend
and substitute for such agreement the Amended and Restated Registration Rights
Agreement in substantially the form attached hereto as Exhibit B (the "NEW
REGISTRATION RIGHTS AGREEMENT") effective as of the Closing. If as of the
Closing, the requisite holders of registration rights under the Existing
Registration Rights Agreement shall not have agreed to amend and substitute for
such agreement the New Registration Rights Agreement, then Parent and VHA shall
enter into, and Parent shall use its reasonable best efforts to cause the
holders of registration rights under the Existing Registration Rights Agreement
to enter into, effective as of the Closing, a registration rights agreement (the
"ALTERNATIVE REGISTRATION RIGHTS AGREEMENT") modeled upon the New Registration
Rights Agreement and only differing from the New Registration Rights Agreement
to the extent necessary so that the Alternative Registration Rights Agreement
does not conflict with or violate the Existing Registration Rights Agreement.

     6.7 Public Disclosure.  Parent and VHA will consult with each other, and to
the extent practicable, agree, before issuing any press release or otherwise
making any public statement with respect to this Agreement and will not issue
any such press release or make any such public statement prior to such
consultation, except as may be required by law or any listing agreement with a
national securities exchange. The parties have agreed to the text of the press
release announcing the signing of this Agreement.

                                  ARTICLE VII

                   CONDITIONS TO VHA'S OBLIGATIONS AT CLOSING

     The obligations of VHA under Sections 1 and 2 of this Agreement are subject
to the fulfillment or waiver, on or before the Closing, of each of the following
conditions:

          7.1 Representations and Warranties.  The representations and
     warranties of Parent contained in this Agreement, disregarding all
     qualifications and exceptions contained therein relating to materiality or
     Material Adverse Effect or any similar standard or qualification, shall be
     true and correct at and as of the Closing as if made at and as of the
     Closing (other than representations and warranties that address

                                      B-26
<PAGE>   73

     matters only as of a particular date, which shall be true and correct as of
     such date), except where the failure of such representations or warranties
     to be true or correct would not have, individually or in the aggregate, a
     Material Adverse Effect on Parent. It is understood that, for purposes of
     determining the accuracy of such representations and warranties, any update
     of or modification to the Parent Disclosure Letter made or purported to
     have been made after the execution of this Agreement shall be disregarded.
     VHA shall have received a certificate with respect to the foregoing signed
     on behalf of Parent by the Chief Executive Officer or the Chief Financial
     Officer of Parent.

          7.2 Performance.  Parent shall have performed and complied in all

     LAW") and the registration and/or qualification requirements of all other
     applicable state securities laws.

          7.4 Consents.  (i) All required approvals or consents of any
     Governmental Entity or other person in connection with the consummation of
     the transactions contemplated hereby shall have been obtained (and all
     relevant statutory, regulatory or other governmental waiting periods, shall
     have expired) unless the failure to receive any such approval or consent
     would not be reasonably likely, directly or indirectly, to result in a
     Material Adverse Effect on Parent and its subsidiaries, taken as a whole,
     and (ii) all such approvals and consents which have been obtained shall be
     on terms that are not reasonably likely, directly or indirectly, to result
     in a Material Adverse Effect on Parent and its subsidiaries, taken as a

     the transactions contemplated hereby shall have been obtained (and all

                                   ARTICLE IX

                                  TERMINATION

     9.1 Termination.  This Agreement may be terminated prior to the Closing,
whether before or after the requisite approval of the issuance of the Shares,
the Warrant and the Warrant Stock by Parent's stockholders:

          (a) by mutual written consent duly authorized by the Boards of
     Directors of Parent and VHA;

          (b) by either Parent or VHA if the Closing shall not have occurred by
     September 30, 2000 for any reason; provided, however, that the right to
     terminate this Agreement under this Section 9.1(b) shall not be available
     to any party whose action or failure to act has been a principal cause of
     or resulted in the failure of the Closing to occur on or before such date
     and such action or failure to act constitutes a breach of this Agreement or
     the Outsourcing Agreement;

          (c) by either Parent or VHA if a Governmental Entity shall have issued
     an order, decree or ruling or taken any other action, in any case having
     the effect of permanently restraining, enjoining or otherwise prohibiting
     the Closing, which order, decree, ruling or other action is final and
     nonappealable;

          (d) by either Parent or VHA, if the approval of the issuance of the
     Shares, the Warrant and the Warrant Stock by the stockholders of Parent
     shall not have been obtained by reason of the failure to obtain the
     required vote at a meeting of Parent stockholders duly convened therefor or
     at any adjournment thereof;

          (e) by either Parent or VHA, if the Outsourcing Agreement is validly
     terminated according to its terms by a party thereto; or

          (f) by VHA, at any time prior to the Parent Stockholders' Meeting, if
     a Triggering Event (as defined below) shall have occurred; provided,
     however, that VHA shall not have the right to terminate this Agreement
     under this Section 7.1(f) in response to the occurrence of the Triggering
     Event set forth in clause (iii) of the definition thereof if at the time
     the event set forth in such clause (iii) occurs VHA is in material breach
     of this Agreement, or VHA, Novation or HPPI is in material breach of the
     Outsourcing Agreement, which breach has not been cured as of such time.

     For the purposes of this Agreement, a "TRIGGERING EVENT" shall be deemed to
have occurred if: (i) the Board of Directors of Parent or any committee thereof
shall for any reason have withdrawn or shall have amended or modified in a
manner adverse to VHA its recommendation in favor of the approval of the Parent
Stockholder Approval; (ii) Parent shall have failed to include in the Proxy
Statement the recommendation of
                                      B-28
<PAGE>   75

the Board of Directors of Parent in favor of the approval of the Parent
Stockholder Approval; (iii) the Board of Directors of Parent fails to reaffirm
its recommendation in favor of the approval of the Parent Stockholder Approval
within 10 business days after VHA requests in writing that such recommendation
be reaffirmed at any time following the public announcement of a Parent
Acquisition Proposal; (iv) the Board of Directors of Parent or any committee
thereof shall have approved or publicly recommended any Parent Acquisition
Proposal; (v) Parent shall have entered into any letter of intent of similar
document or any agreement, contract or commitment accepting any Parent
Acquisition Proposal; or (vi) Parent shall have materially breached any of the
provisions of Sections 5.2 or 5.4(a) or (b).

     9.2 Notice of Termination; Effect of Termination.  Any proper termination
of this Agreement under Section 9.1 will be effective immediately upon the
delivery of written notice of the terminating party to the other party hereto.
In the event of the termination of this Agreement as provided in Section 9.1,
this Agreement shall be of no further force or effect, except (i) as set forth
in this Section 9.2, Section 9.3 and Article X, each of which shall survive the
termination of this Agreement, and (ii) nothing herein shall relieve either
party from liability for any willful breach of this Agreement.

     9.3 Parent Payment.  In the event that this Agreement is terminated by VHA
pursuant to Section 9.1(f), Parent shall promptly, but in no event later than
two days after the date of such termination, pay VHA a fee equal to $12 million
in immediately available funds. In the event that (A) following the date of this
Agreement and prior to the Parent Stockholders' Meeting, a person has publicly
announced a bona fide Parent Acquisition Proposal, (B) this Agreement is
terminated by Parent or VHA pursuant to Section 9.1(d), and (C) within nine
months following the termination of this Agreement pursuant to Section 9.1(d),
either the Parent Acquisition contemplated by such Parent Acquisition Proposal
is consummated, or Parent enters into an agreement providing for a Parent
Acquisition and such Parent Acquisition is later consummated with the person (or
another person controlling, controlled by or under common control with, such
person) with whom such agreement was entered into (regardless of when such
consummation occurs if Parent has entered into such an agreement within such
nine-month period), Parent shall promptly, but in no event later than two days
after the consummation of such Parent Acquisition, pay VHA a fee equal to $12
million in immediately available funds. Parent acknowledges that the agreements
contained in this Section 9.3 are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, VHA would
not enter into this Agreement. Accordingly, if Parent fails to pay in a timely
manner the amounts due pursuant to this Section 9.3, and, in order to obtain
such payment, VHA makes a claim that results in a judgment against Parent for
the amounts set forth in this Section 9.3, Parent shall pay to VHA its
reasonable costs and expenses (including reasonable attorneys' fees and
expenses) in connection with such suit, together with interest on the amounts
set forth in this Section 9.3 at the prime rate of The Chase Manhattan Bank in
effect on the date such payment was required to be made.

                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                               NEOFORMA.COM, INC.

No. V-1                                            Void after             , 2010

     THIS CERTIFIES THAT VHA Inc., a Delaware corporation ("VHA" or the
"HOLDER"), or its permitted assigns is entitled to purchase under this Warrant
up to 30,845,020 shares (the "SHARES") of common stock, par value $0.001 per
share ("COMMON STOCK"), of Neoforma.com, Inc., a Delaware corporation
("NEOFORMA" or the "COMPANY") at a per share price of $0.01 (the "EXERCISE
PRICE") subject to the provisions and upon the terms and conditions hereinafter
set forth.

     This Warrant is issued this        day of             , 2000 (the "ISSUE
DATE") pursuant to that certain Amended and Restated Common Stock and Warrant
Agreement amended and restated as of May 24, 2000 (the "STOCK AND WARRANT
AGREEMENT"), by and between the Company and the Holder.

     1. Vesting and Term.

     1.1 Vesting.  Upon issuance, this Warrant shall not be exercisable or
vested with respect to any Shares. A total of 23,133,764 Shares shall be
eligible for vesting in accordance with Section 1.1.2 below ("TRANCHE A SHARES")
and a total of 7,711,256 Shares shall be eligible for vesting in accordance with
Section 1.1.3 below ("TRANCHE B SHARES"). Shares with respect to which this
Warrant becomes vested and exercisable are referred to as "VESTED SHARES."

     1.1.1. Definitions.

     "CUMULATIVE SIGNED PURCHASING VOLUME" means, as of any Determination Date,
the sum of (x) the cumulative dollar volume of purchases by Healthcare
Organizations that are members or patrons of VHA (calculated, for each such
Healthcare Organization, by multiplying (A) the amount of Novation LLC contract
purchases (as reported in the SRIS system maintained for Novation LLC's benefit)
by such Healthcare Organization during the most recent complete calendar year
ending prior to the first
                                      B-34
<PAGE>   81

Determination Date on or prior to which such Healthcare Organization Signed-Up
with Neoforma by (B) 2.4 (the "BASE AMOUNT")) and that Signed-Up with Neoforma
on or prior to such Determination Date, plus (y) 80.4% of the cumulative dollar
volume of purchases by Healthcare Organizations that are members or patrons of
Healthcare Purchasing Partners International, LLC (using, for each such
Healthcare Organization, its Base Amount) and that Signed-Up with Neoforma on or
prior to such Determination Date, provided that (i) for purposes of computing
the first Base Amount for each Healthcare Organization, such Base Amount will be
increased by 3.625% and (ii) in addition to the increase in the Base Amount for
any Healthcare Organization pursuant to the preceding clause (i), the Base
Amount for each Healthcare Organization shall also be increased annually by
7.25% when computing Cumulative Signed Purchasing Volume for Determination Dates
which are subsequent to the first Determination Date on or prior to which a
particular Healthcare Organization Signed-Up with Neoforma. For purposes of
clarity, the parties agree that once a Healthcare Organization is deemed to have
"Signed-Up" with Neoforma, its Cumulative Signed Purchasing Volume, as computed
and increased under the formula set forth in this definition, shall be included
in the computation of Cumulative Signed Purchasing Volume for all Determination
Dates arising on or after the date such Healthcare Organization Signed-Up with
Neoforma, whether or not such Healthcare Organization continues to do business
with Neoforma.

     "HEALTHCARE ORGANIZATION" shall mean any facility providing health care
services.

     "PREFERRED PROVIDER" means the Healthcare Organization agrees to use the
Neoforma internet-based system for at least 50% of its internet-based purchases
of Novation contracted products.

     "SIGNED-UP" means, with respect to any Healthcare Organization, that such
Healthcare Organization and Neoforma have entered into a written agreement,
arrangement or understanding for Neoforma to be the Preferred Provider of an
Internet-based system for the acquisition of Novation contracted products by
such Healthcare Organization.

     1.1.2. Vesting Requirements for Tranche A Shares.

     1. 5,783,441 Tranche A Shares shall become Vested Shares on June 30, 2001
(the "FIRST DETERMINATION DATE") if Cumulative Signed Purchasing Volume as of
the First Determination Date is at least $2,328 million (the "FIRST TRANCHE A
TARGET AMOUNT").

     2. 5,783,441 Tranche A Shares shall become Vested Shares on June 30, 2002
(the "SECOND DETERMINATION DATE") if Cumulative Signed Purchasing Volume as of
the Second Determination Date is at least $6,233 million (the "SECOND TRANCHE A
TARGET AMOUNT").

     3. 5,783,441 Tranche A Shares shall become Vested Shares on June 30, 2003
(the "THIRD DETERMINATION DATE") if Cumulative Signed Purchasing Volume as of
the Third Determination Date is at least $9,629 million (the "THIRD TRANCHE A
TARGET AMOUNT").

     4. 5,783,441 Tranche A Shares shall become Vested Shares on June 30, 2004
(the "FOURTH DETERMINATION DATE") if Cumulative Signed Purchasing Volume as of
the Fourth Determination Date is at least $13,253 million (the "FOURTH TRANCHE A
TARGET AMOUNT").

     5. In the event the Tranche A Target Amount of Cumulative Signed Purchasing
Volume specified in any of Section 1.1.2 paragraphs 1, 2, 3 or 4 above is not
achieved as of the particular Determination Date specified in such paragraph
(such shortfall below a particular Tranche A Target Amount being referred to as
a "TRANCHE A SHORTFALL AMOUNT"), then the number of Tranche A Shares which shall
become Vested Shares at a particular Determination Date pursuant to Section
1.1.2 paragraphs 1, 2, 3 or 4 shall equal the product of 5,783,441 and a
fraction, the numerator of which is the Cumulative Signed Purchasing Volume as
of the Determination Date in question and the denominator of which is the
Tranche A Target Amount for the Determination Date in question. By way of
example, using the formula in the preceding sentence, if as of June 30, 2001,
Cumulative Signed Purchasing Volume is $2,000 million, 4,968,592 Tranche A
Shares shall become Vested Shares:

                  5,783,441 X 2,000 = 4,968,592 Vested Shares
                              -----
                              2,328

                                      B-35
<PAGE>   82

     If there is a Tranche A Shortfall Amount relating to a particular
Determination Date, then the number of Tranche A Shares which will not vest due
to such shortfall shall equal 5,783,441 minus the number of Tranche A Shares
which became Vested Shares on such Determination Date (the "TRANCHE A SHORTFALL
SHARES"). Using the facts set forth in the preceding example, if as of June 30,
2001, Cumulative Signed Purchasing Volume is $2,000 million, and 4,968,592
Tranche A Shares become Vested Shares, then 814,849 Tranche A Shares shall be
deemed Tranche A Shortfall Shares as of the First Determination Date:

           5,783,441 - 4,968,592 = 814,849 Tranche A Shortfall Shares

     A Determination Date as of which there is a Tranche A Shortfall Amount is
referred to as a "TRANCHE A SHORTFALL DETERMINATION DATE". A Determination Date
which occurs immediately after a Tranche A Shortfall Determination Date is
referred to as a "TRANCHE A CATCH UP DETERMINATION DATE". If as of a Tranche A
Catch Up Determination Date, the applicable Tranche A Target Amount for such
Tranche A Catch Up Determination Date is met or exceeded, then the Tranche A
Shortfall Shares which did not vest on such Tranche A Shortfall Determination
Date shall immediately become Vested Shares on the Tranche A Catch Up
Determination Date, it being agreed that if the Tranche A Target Amount relating
to such Tranche A Catch Up Determination Date is not met, such Tranche A
Shortfall Shares shall never become vested. By way of example, if the Tranche A
Shortfall Amount on the First Determination Date is $328 million resulting in
814,849 Tranche A Shortfall Shares, and as of the Second Determination Date
(which, in this example, is the Tranche A Catch Up Determination Date with
respect to the First Determination Date) the Second Tranche A Target Amount of
Cumulative Signed Purchasing Volume of $6,233 million is met, then the 814,849
Tranche A Shortfall Shares relating to the First Determination Date which had
become a Tranche A Shortfall Determination Date will become Vested Shares on the
Second Determination Date, provided however, that if as of the Second
Determination Date Cumulative Signed Purchasing Volume is less than $6,233
million, the 814,849 Tranche A Shortfall Shares relating to the First
Determination Date shall never become vested, even if as of the Third
Determination Date or the Fourth Determination Date the relevant Tranche A
Target Amount for such Determination Date is met or exceeded.

     1.1.3 Vesting Requirements for Tranche B Shares.

     1. 1,927,814 Tranche B Shares shall become Vested Shares on the First
Determination Date if Cumulative Signed Purchasing Volume as of the First
Determination Date is at least $3,104 million (the "FIRST TRANCHE B TARGET
AMOUNT").

     2. 1,927,814 Tranche B Shares shall become Vested Shares on the Second
Determination Date if Cumulative Signed Purchasing Volume as of the Second
Determination Date is at least $8,311 million (the "SECOND TRANCHE B TARGET
AMOUNT").

     3. 1,927,814 Tranche B Shares shall become Vested Shares on the Third
Determination Date if Cumulative Signed Purchasing Volume as of the Third
Determination Date is at least $12,838 million (the "THIRD TRANCHE B TARGET
AMOUNT").

     4. 1,927,814 Tranche B Shares shall become Vested Shares on the Fourth
Determination Date if Cumulative Signed Purchasing Volume as of the Fourth
Determination Date is at least $17,671 million (the "FOURTH TRANCHE B TARGET
AMOUNT").

     5. In the event the Tranche B Target Amount of Cumulative Signed Purchasing
Volume specified in any of Section 1.1.3 paragraphs 1, 2, 3, or 4 above is not
achieved as of the particular Determination Date specified in such paragraph
(such shortfall below a particular Tranche B Target Amount being referred to as
a "TRANCHE B SHORTFALL AMOUNT"), then the number of Tranche B Shares which shall
become Vested Shares at a particular Determination Date pursuant to Section
1.1.3 paragraphs 1, 2, 3 or 4 shall equal the product of 1,927,814 and a
fraction, the numerator of which is the Cumulative Signed Purchasing Volume as
of the Determination Date in question minus the Tranche A Target Amount for the
Determination Date in question and the denominator of which is the Tranche B
Target Amount for the Determination Date in question minus the Tranche A Target
Amount for the Determination Date in question. It is agreed that no Tranche B
Shares will become Vested Shares on a particular Determination Date if the
Tranche A Target Amount relating to

                                      B-36
<PAGE>   83

such Determination Date is not exceeded. By way of example, if as of June 30,
2001, Cumulative Signed Purchasing Volume is $3,000 million, 1,669,447 Tranche B
Shares shall become Vested Shares:

              1,927,814 X 3,000 - 2,328 = 1,669,447 Vested Shares
                          -------------
                          3,104 - 2,328

     If there is a Tranche B Shortfall Amount relating to a particular
Determination Date, then the number of Tranche B Shares which will not vest due
to such shortfall shall equal 1,927,814 minus the number of Tranche B Shares
which became Vested Shares on such Determination Date (the "TRANCHE B SHORTFALL
SHARES"). If no Tranche B Shares became Vested Shares on a Determination Date,
then there will be 1,927,814 Tranche B Shortfall Shares with respect to the
Determination Date in question. Using the facts set forth in the preceding
example, if as of June 30, 2001, Cumulative Signed Purchasing Volume is $3,000
million, and 1,669,447 Tranche B Shares become Vested Shares, then 258,367
Tranche B Shares shall be deemed Tranche B Shortfall Shares as of the First
Determination Date:

           1,927,814 - 1,669,447 = 258,367 Tranche B Shortfall Shares

     A Determination Date as of which there is a Tranche B Shortfall Amount is
referred to as a "TRANCHE B SHORTFALL DETERMINATION DATE". A Determination Date
which occurs immediately after a Tranche B Shortfall Determination Date is
referred to as a "TRANCHE B CATCH UP DETERMINATION DATE". If as of a Tranche B
Catch Up Determination Date, the applicable Tranche B Target Amount for such
Tranche B Catch Up Determination Date is met or exceeded, then the Tranche B
Shortfall Shares which did not vest on such Tranche B Shortfall Determination
Date shall immediately become Vested Shares on the Tranche B Catch Up
Determination Date, it being agreed that if the Tranche B Target Amount relating
to such Tranche B Catch Up Determination Date is not met, such Tranche B
Shortfall Shares shall never become vested. By way of example, if the Tranche B
Shortfall Amount on the First Determination Date is $104 million resulting in
258,367 Tranche B Shortfall Shares, and as of the Second Determination Date
(which, in this example, is the Tranche B Catch Up Determination Date with
respect to the First Determination Date) the Second Tranche B Target Amount of
Cumulative Signed Purchasing Volume of $8,311 million is met, then the 258,367
Tranche B Shortfall Shares relating to the First Determination Date which had
become a Shortfall Determination Date will become Vested Shares on the Second
Determination Date, provided however, that if as of the Second Determination
Date Cumulative Signed Purchasing Volume is less than $8,311 million, the
258,367 Tranche B Shortfall Shares relating to the First Determination Date
shall never become vested, even if as of the Third Determination Date or the
Fourth Determination Date the relevant Tranche B Target Amount for such
Determination Date is met or exceeded.

     1.2 Acceleration of Vesting.  In the event of a merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving the Company in which all shares of Common Stock of the
Company are converted into cash, or a cash tender offer for all shares of Common
Stock is consummated, this Warrant will become fully exercisable as to all of
the Shares effective upon consummation of such transaction, and this Warrant
will expire on the later of the date of such consummation or twenty days after
written notice of such transaction, provided that the Holder may exercise this
Warrant contingent on the consummation of such transaction.

     1.3 Termination Date.  Unless this Warrant expires pursuant to Section 1.2,
this Warrant shall remain exercisable with respect to Vested Shares, if any,
until 5:00 p.m. California time on the tenth anniversary of the Issue Date at
which time the Warrant shall expire and be of no further force and effect.

     2. Exercise or Conversion.

     2.1 Method of Exercise; Payment; Issuance of New Warrant.  This Warrant may
be exercised by the Holder, in whole or in part and from time to time as to
Vested Shares, by the surrender of this Warrant (with a notice of exercise in
the form attached as Exhibit A and the investment representation certificate in
the form attached as Exhibit B, each duly executed) at the principal office of
the Company and by the payment to the Company by check or wire transfer of an
amount equal to the then current Exercise Price per share multiplied by the
number of Vested Shares then being purchased (the "AGGREGATE EXERCISE PRICE").
The Holder shall be deemed to have become the holder of record of, and shall be
treated for all purposes as the record holder of the
                                      B-37
<PAGE>   84

Vested Shares represented thereby, and such Vested Shares shall be deemed to
have been issued, immediately prior to the close of business on the date or
dates upon which this Warrant is exercised. In the event of any exercise of this
Warrant, certificates for the Vested Shares so purchased shall be delivered to
the Holder as soon as possible and in any event within ten business days of
receipt of such notice by the Company and, unless this Warrant has been fully
exercised or expired, a new Warrant representing the portion of the Shares, if
any, with respect to which this Warrant shall not then have been exercised shall
also be issued to the Holder as soon as possible and in any event within such
ten business day period.

     2.2 Right to Convert Warrant into Stock; Net Issuance.  In addition to and
without limiting the rights of the Holder under the terms of this Warrant, the
Holder may elect to exercise this Warrant with respect to then Vested Shares
(the "CONVERSION RIGHT"), the aggregate value of which Vested Shares shall be
equal to the "in-the-money" value of this Warrant or the portion thereof being
converted as set forth below. The Conversion Right may be exercised by the
Holder by surrender of this Warrant at the principal office of the Company
together with notice of the Holder's intention to exercise the Conversion Right,
in which event the Company shall issue to the Holder a number of Vested Shares
computed using the following formula:

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

Where:

     X = The number of Vested Shares to be issued to the Holder.

     Y = The number of Vested Shares representing the portion of this Warrant
         that is being converted.

     A = The fair market value of one Share.

     B = The Exercise Price (as adjusted to the date of such calculations).

For purposes of this Section 2.2, the "fair market value" per Share shall mean
the market price of one share of Common Stock on the last business day before
the effective date of exercise of the Conversion Right. If the Common Stock is
then traded on a national securities exchange or admitted to unlisted trading
privileges on such an exchange, or is listed on the Nasdaq Stock Market (the
"NASDAQ MARKET"), the market price as of a specified day shall be the last
reported sale price of one share of Common Stock on such exchange or on the
Nasdaq Market on such date or if no such sale is made on such day, the mean of
the closing bid and asked prices for such day on such exchange or on the Nasdaq
Market. If the Common Stock is not so listed or admitted to unlisted trading
privileges, the market price as of a specified day shall be the mean of the last
bid and asked prices for one share of Common Stock reported on such date (x) by
the NASD or (y) if reports are unavailable under clause (x) above by the
National Quotation Bureau Incorporated. If the Common Stock is not so listed or
admitted to unlisted trading privileges and bid and asked prices are not
reported, the market price of one share of Common Stock as of a specified day
shall be determined in good faith by written resolution of the Board of
Directors of the Company.

     2.3 Automatic Conversion.  In the event of termination of this Warrant
pursuant to Section 1 above, to the extent that this Warrant is then exercisable
and such exercise would result in the issuance of Shares to the Holder, this
Warrant shall be deemed automatically exercised in full under Section 2.2 above
immediately prior to the time at which it would otherwise expire.

     2.4 HSR Compliance.  Exercise or conversion of this Warrant is subject to
compliance by the Holder with all applicable filing requirements, and expiration
of all applicable waiting periods, under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR ACT"). The Company will cooperate
with the Holder in making all applicable filings under the HSR Act, provided,
however, that the Holder shall pay all applicable filing fees.

     3. Securities Fully Paid; Reservation of Shares.  All Shares that may be
issued upon the exercise of the rights represented by this Warrant, upon
issuance, will be fully paid and nonassessable, and free from all taxes, liens
and charges with respect to the issue thereof. During the period within which
the rights represented by the Warrant may be exercised, the Company will at all
times have authorized and reserved for the purpose of

                                      B-38
<PAGE>   85

issuance upon exercise of the purchase rights evidenced by this Warrant, a
sufficient number of shares of Common Stock to provide for the exercise of the
rights represented by this Warrant. The Shares to be issued upon exercise or
conversion of this Warrant shall be approved for listing on the Nasdaq Market,
subject to official notice of issuance.

     4. Adjustment of Exercise Price and Number of Shares.  The Exercise Price
and the number and kind of securities or other property purchasable upon the
exercise of the Warrant shall be subject to adjustment from time to time upon
the occurrence of certain events, as follows:

     4.1 Reclassification or Merger.  In case of any reclassification, change or
conversion of securities in the class issuable upon exercise of this Warrant
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination), or in
case of any merger of the Company with or into another corporation (other than a
merger with another corporation in which the Company is a continuing corporation
and which does not result in any reclassification or change of outstanding
securities issuable upon exercise of this Warrant), unless this Warrant shall
have been exercised or terminated in accordance with its terms, this Warrant
shall thereafter be exercisable solely for the kind and amount of consideration,
including but not limited to shares of stock, other securities, money and
property, that the Holder would have received upon such reclassification,
change, conversion or merger if the Holder had exercised this Warrant in full
prior to such reclassification, change, conversion or merger. The provisions of
this subparagraph shall similarly apply to successive reclassifications,
changes, conversions or mergers. The Company agrees to make appropriate
provision in any definitive agreements providing for such a transaction in order
to carry out the terms of this Section.

     4.2 Subdivisions or Combination of Shares.  If at any time while this
Warrant remains outstanding and unexpired the Company shall subdivide or combine
the securities of the class issuable upon exercise of this Warrant, the Exercise
Price and the number of Shares issuable upon exercise hereof shall be
proportionately adjusted.

     4.3 Stock Dividends.  If, at any time while this Warrant is outstanding and
unexpired, the Company shall pay a dividend payable in securities of the class
issuable upon exercise of this Warrant (except any distribution specifically
provided for in the foregoing subparagraphs 4.1 and 4.2), then the Exercise
Price shall be adjusted, from and after the date of determination of
stockholders entitled to receive such dividend or distribution, to that price
determined by multiplying the Exercise Price in effect immediately prior to such
date of determination by a fraction, the numerator of which shall be the total
number of shares of such class of securities outstanding immediately prior to
such dividend or distribution, and the denominator of which shall be the total
number of shares of such class of securities outstanding immediately after such
dividend or distribution, and the number of Shares subject to this Warrant shall
be proportionately adjusted.

     4.4 Common Stock Rights.  If, at any time while this Warrant is outstanding
and unexpired, the Company shall pay a dividend or other distribution on all
Common Stock consisting of, or shall otherwise issue to all holders of Common
Stock, rights, warrants or options (not being available on an equivalent basis
to the Holders of this Warrant upon exercise) entitling the holders of Common
Stock to subscribe for or purchase Common Stock at a price per share less than
the current market price (determined as provided in Section 2.2) of a share of
Common Stock on the date fixed for the determination of stockholders entitled to
receive such rights, warrants or options (other than pursuant to a dividend
reinvestment plan), the Exercise Price shall be decreased by multiplying the
then current Exercise Price by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock
which the aggregate of the offering price of the total number of shares of
Common Stock so offered for subscription or purchase would purchase at such
current market price, and the denominator of which shall be the number of shares
of Common Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such decrease to become effective immediately after
the opening of business on the day following the date fixed for such
determination. In the event that such rights or warrants are not so issued, the
Exercise Price shall again be adjusted to be the Exercise Price which would then
be in effect if such date fixed for the determination of stockholders entitled
to receive such rights,

                                      B-39
<PAGE>   86

warrants or options had not been fixed. Upon adjustment of the Exercise Price
pursuant to this Section 4.4, the number of shares subject to issuance upon
exercise of this Warrant shall be adjusted by multiplying such number of shares
prior to such adjustment by a fraction, the numerator of which is the Exercise
Price in effect immediately prior to such adjustment and the denominator of
which is the Exercise Price in effect immediately after giving effect to such
adjustment. In making any determinations under this Section 4.4, there shall be
taken into account any consideration received for such rights, warrants or
options, the value of which consideration, if other than cash, shall be fixed in
good faith by the Board of Directors of the Company, whose determination shall
be final.

     4.5 Distributions of Property.  If, at any time while this Warrant is
outstanding and unexpired, the Company shall pay a dividend or other
distribution on all Common Stock consisting of evidences of its indebtedness or
assets (excluding any dividend or distribution paid in cash, or any dividend or
distribution described in Sections 4.2, 4.3 or 4.4 of this Warrant), the
Exercise Price shall be decreased by multiplying the then current Exercise Price
by a fraction, the numerator of which shall be the current market price
(determined as provided in Section 2.2) of a share of Common Stock on the date
fixed for the determination of stockholders entitled to receive such dividend or
distribution less the fair market value (as determined by the Board of Directors
of Company, whose determination shall be final) of the portion of indebtedness
or assets so distributed applicable to one share of Common Stock and the
denominator of which shall be such current market price of a share of Common
Stock, such decrease to become effective immediately after the opening of
business on the day following the date fixed for such determination. In the
event that such dividend or distribution is not so made, the Exercise Price
shall again be adjusted to be the Exercise Price which would then be in effect
if such date fixed for the determination of stockholders entitled to receive
such dividend or distribution had not been fixed. Upon adjustment of the
Exercise Price pursuant to this Section 4.5, the number of shares subject to
issuance upon exercise of this Warrant shall be adjusted by multiplying such
number of shares prior to such adjustment by a fraction, the numerator of which
is the Exercise Price in effect immediately prior to such adjustment and the
denominator of which is the Exercise Price in effect immediately after giving
effect to such adjustment.

     4.6 Notice of Adjustments.  Whenever the Exercise Price shall be adjusted
pursuant to the provisions hereof, the Company shall within thirty days of such
adjustment deliver a certificate to the Holder signed by its chief financial
officer setting forth, in reasonable detail, the event requiring the adjustment,
the amount of the adjustment, the method by which such adjustment was
calculated, and the number of Shares subject to this Warrant and the Exercise
Price therefor, as applicable, after giving effect to such adjustment.

     5. Compliance with Securities Laws; Restrictions on Transfer.

     5.1 Accredited Investor.  This issuance of this Warrant is conditioned
upon, and by its acceptance hereof the Holder hereby confirms, that the Holder
is an "accredited investor" as that term is defined under Regulation D under the
Securities Act of 1933, as amended.

     5.2 Legend.  Upon issuance, certificates evidencing the Shares shall bear
legends in substantially the form set forth in the Purchase Agreement.

     5.3 Transfer Restrictions; Compliance with Securities Laws on
Transfer.  This Warrant may not be transferred in whole or in part without the
prior written consent of the Company, except that such consent shall not be
required for the transfer of all or any part of this Warrant covering Vested
Shares. Any purported transfer of this Warrant in violation of the foregoing
restriction shall be void, and the Company shall not recognize any such
purported transfer on the securities ledger of the Company. In addition, no
permitted transfer of this Warrant or the Shares may be made without compliance
with applicable federal and state securities laws by the transferor and the
transferee (including, without limitation, the delivery of investment
representation letters and legal opinions reasonably satisfactory to the
Company). The Company will reasonably cooperate with the Holder in connection
with any permitted transfer of this Warrant, including by issuing new
certificates representing the Warrant and any portion thereof so transferred.

                                      B-40
<PAGE>   87

     6. Fractional Shares.  No fractional Shares will be issued in connection
with any exercise hereunder, but in lieu of such fractional Shares the Company
shall make a cash payment therefor upon the basis of the Exercise Price then in
effect.

     7. Modification and Waiver.  This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

     8. Notices.

     8.1 Notice of Certain Events.  The Company shall provide the Holder with at
least twenty days notice (or such greater amount of notice as Delaware law
requires to be given to stockholders having the right to vote at a meeting on
any Sale Event, as defined herein) prior to (i) a merger of the Company with or
into, the consolidation of the Company with, or the sale by the Company of all
or substantially all of its assets to, another person or entity (other than such
a transaction wherein the stockholders of the Company prior to such transaction
retain or obtain a majority of the voting capital stock of the surviving,
resulting or purchasing entity) (a "SALE EVENT"), (ii) any liquidation,
dissolution or winding up of the Company or (iii) the record date for any cash
or other dividend or distribution declared on the Shares (each, a "NOTICE
EVENT"). If a notice is provided pursuant to subsection (i) or (ii) of the
previous sentence, the notice will indicate the expected date of the Notice
Event.

     In connection with the purchase of the above-listed securities (the
"SHARES"), the undersigned (the "HOLDER") represents to the Company as follows:

     The Shares to be purchased by or delivered to the Holder hereunder will be
acquired for investment for such Holder's own account, not as a nominee or
agent, and not with a view to the public resale or distribution thereof within
the meaning of the Securities Act of 1933, as amended ("1933 ACT"), and Holder
represents that it has no present intention or agreement to sell, grant any
participation in, or otherwise distribute any of the Shares to be acquired
hereunder in any public resale or distribution within the meaning of the 1933
Act. Holder also represents that it has not been formed for the specific purpose
of acquiring Securities under this Agreement.

     Holder has received or has had full access to all the information it
considers necessary or appropriate to make an informed investment decision with
respect to the Shares to be purchased under this Agreement. Holder further has
had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of the offering of the Shares and to obtain
additional information (to the extent the Company possessed such information or
could acquire it without unreasonable effort or expense) necessary to verify any
information furnished to Holder or to which Holder had access.

     Holder understands that the purchase of the Shares involves substantial
risk. Holder: (i) has experience as an investor in securities of companies in
the development stage and acknowledges that Holder is able to fend for itself,
can bear the economic risk of Holder's investment in the Shares and has such
knowledge and experience in financial or business matters that Holder is capable
of evaluating the merits and risks of this investment in the Shares and
protecting its own interests in connection with this investment and/or (ii) has
a preexisting personal or business relationship with the Company and certain of
its officers, directors or controlling persons of a nature and duration that
enables Holder to be aware of the character, business acumen and financial
circumstances of such persons. Holder is an "accredited investor" within the
meaning of Regulation D promulgated under the 1933 Act.

     Holder understands that the Shares are characterized as "restricted
securities" under the 1933 Act inasmuch as they are being acquired from the
Company in a transaction not involving a public offering and that under the 1933
Act and applicable regulations thereunder such securities may be resold without
registration under the 1933 Act only in certain limited circumstances. In this
connection, such Holder represents that Holder is familiar with Rule 144 of the
Securities and Exchange Commission, as presently in effect, and understands the
resale limitations imposed thereby and by the 1933 Act.

     At no time was Holder presented with or solicited by any publicly issued or
circulated newspaper, mail, radio, television or other form of general
advertising or solicitation in connection with the offer, sale and purchase of
the Shares.

     Without in any way limiting the representations set forth above, Holder
further acknowledges that the Shares are subject to limitations on disposition
thereof set forth in the Warrant and in that certain Amended

                                      B-45

and Restated Common Stock and Warrant Agreement, dated as of May 24, 2000 by and
between the Company and Holder, and acknowledges that Holder is bound by such
restrictions.

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
     AS AMENDED (THE "ACT"). SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE

     RESTRICTIONS, INCLUDING TRANSFERABILITY AND VOTING, AS SET FORTH IN THE
     REGISTRATION RIGHTS AGREEMENT, A COPY OF WHICH MAY BE OBTAINED FROM THE
     COMPANY.

     The Investors and Holders of Restricted Securities consent to the Company

transfer not involving a change in beneficial ownership, or (ii) in transactions
involving the distribution without consideration of Restricted Securities by an
Investor which is a partnership to any of its partners, or retired partners, or
to the estate of any of its partners or retired partners, (iii) a transfer to an
Affiliate, an affiliated fund, partnership or Company, which is not a competitor
of the Company, subject to compliance with applicable securities laws, or (iv)
transfers in compliance with Rule 144, so long as the Company is furnished with
satisfactory evidence of compliance with such Rule), unless there is in effect a
registration statement under the Securities Act covering the proposed transfer,
the holder thereof shall give written notice to the Company of such holder's
intention to effect such transfer, sale, assignment or pledge. Each such notice
shall describe the manner and circumstances of the proposed transfer, sale,
assignment or pledge in sufficient detail, and shall be accompanied by either of
the following, at such holder's expense: (i) a written opinion of legal counsel
who shall, and whose legal opinion shall, be reasonably satisfactory to the
Company addressed to the Company, to the effect that the proposed transfer of
the Restricted Securities may be effected without registration under the
Securities Act, or (ii) a "no action" letter from the Commission to the effect
that the transfer of such securities without registration will not result in a
recommendation by the staff of the Commission that action be taken with respect
thereto, whereupon the holder of such Restricted Securities shall be entitled to
transfer such Restricted Securities in accordance with the terms of the notice
delivered by the holder to the Company. Each certificate evidencing the
Restricted Securities transferred as above provided shall bear, except if such
transfer is made pursuant to Rule 144, the appropriate restrictive legend set
forth in Section 2.2 above, except that such certificate shall not bear such
restrictive legend if in the opinion of counsel for such holder and in the
reasonable opinion of the Company such legend is not required in order to
establish compliance with any provision of the Securities Act.

     2.4 Removal of Restrictions on Transfer of Restricted Securities. Any
legend referred to in Section 2.2 hereof stamped on a certificate evidencing (i)
the Restricted Securities or (ii) any other securities issued in respect of the
Restricted Securities upon any stock split, stock dividend, recapitalization,
merger, consolidation or similar event and the stock transfer instructions and
record notations with respect to such security shall be removed and the Company
shall issue a certificate without such legend to the holder of such
                                      B-49

security if such security is registered under the Securities Act, or if such
holder provides the Company with an opinion of counsel (which may be counsel for
the Company) reasonably acceptable to the Company to the effect that a public
sale or transfer of such security may be made without registration under the
Securities Act or (iii) such holder provides the Company with reasonable
assurances, which may, at the option of the Company, include an opinion of
counsel satisfactory to the Company, that such security can be sold pursuant to
Section (k) of Rule 144 under the Securities Act.

     3. [Intentionally Omitted].

     4. Registration Rights.

     4.1 Requested Registration.

     (a) Requested Registration. If the Company shall receive from the
Initiating Holders a written request that the Company file a registration
statement for (i) at least 75% of the Registrable Securities, (ii) at least 60%
of the Series E Registrable Securities, or (iii) Novation Registrable Securities
having a current market value of at least $30 million, and in the case of clause
(i) or (ii) the aggregate gross proceeds of which registration would equal or
exceed $20,000,000 (any such notice, an "INITIATION NOTICE"), then the Company
will:

          (A) within ten days of the receipt by the Company of the Initiation
     Notice, give written notice of the proposed registration, qualification or
     compliance to all other Holders (the notice in this Section 4.1(a)(i) and
     in Section 4.2(a)(i), each called the "REGISTRATION NOTICE"); and

          (B) use its best efforts to effect, as soon as practicable and in any
     event within ninety (90) days after receipt of the Initiation Notice, such
     registration, qualification or compliance (including, without limitation,
     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) as may be so requested and as would permit or facilitate the
     sale and distribution of all or such portion of such Registrable Securities
     as are specified in such request, together with all or such portion of the
     Registrable Securities of any Holder or Holders joining in such request as
     are specified in a written request received by the Company within 20 days
     after receipt of the Registration Notice from the Company;

     Provided, however, that the Company shall not be obligated to take any
action to effect any such registration, qualification or compliance pursuant to
this Section 4.1:

          (1) Prior to January 24, 2001.

          (2) In any particular jurisdiction in which the Company would be
     required to qualify to do business or to execute a general consent to
     service of process in effecting such registration, qualification or
     compliance;

          (3) During the period starting with the date sixty (60) days prior to
     the Company's estimated date of filing of any registration statement for
     the securities of the Company, and ending (except as provided below) on the
     date six (6) months immediately following the effective date of any
     registration statement pertaining to securities of the Company, provided
     that the Company is actively employing in good faith all reasonable efforts
     to cause such registration statement to become effective, and, provided,
     further, that the standstill period in this clause (3) shall not apply to a
     registration regarding a transaction described in subsection (a) of Rule
     145 as promulgated under the Securities Act ("RULE 145") or with respect to
     securities issued or issuable under an employee benefit plan or other
     similar plan or agreement;

          (4) After the Company has effected two (2) such registrations
     requested by holders of at least 60% of the Series E Initiating Holders,
     three (3) such registrations requested by holders of the Novation
     Registrable Securities, and two (2) additional registrations pursuant to
     this Section 4.1(a), and such registrations have been declared or ordered
     effective. The Company shall not be obligated to effect more than one such
     registration requested by the holders of the Novation Registrable
     Securities in any twelve month period.

                                      B-50
<PAGE>   97

          (5) If the Company shall furnish to such Holders a certificate signed
     by the President of the Company stating that in the good faith judgment of
     the Board of Directors it would be seriously detrimental to the Company or
     its stockholders for a registration statement to be filed in the near
     future, then the Company's obligation to use its best efforts to register,
     qualify or comply under this Section 4.1 shall be deferred for a period not
     to exceed ninety (90) days from the date of receipt of written request from
     the Initiating Holders; provided, however, that the Company shall not
     exercise such right more than once in any twelve (12) month period.

     (b) Underwriting. The Company shall have the right to select one or more
underwriters to manage a registration under Section 4.1, subject to the approval
of the holders of a majority of the Registrable Securities requesting
registration, which will not be unreasonably withheld, conditioned or delayed.
If the registration described in the Registration Notice is a registered public
offering involving an underwriting, the Company shall so advise the Holders as a
part of the Registration Notice. In such event, the right of any Holder to
registration pursuant to Section 4.1 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company. The Company
will not include in any registration under Section 4.1 any securities other than
Registrable Securities and securities to be registered for offering and sale on
behalf of the Company without the prior written consent of the holders of a
majority of the Registrable Securities requesting registration. If the managing
underwriter(s) advise the Company in writing that in their opinion the number of
Registrable Securities and, if permitted hereunder, other securities in such
offering, exceeds the number of Registrable Securities and other securities, if
any, that can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities initially
requesting registration, the Company will include in such registration, prior to
the inclusion of any securities that are not Registrable Securities, the number
of Registrable Securities requested to be included that in the opinion of such
underwriters can be sold in an orderly manner within the price range of such
offering, pro rata among the respective holders thereof on the basis of the
number of Registrable Securities that each such holder has requested the Company
to include in such registration.

     If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such Holder may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the Initiating Holders. The
Registrable Securities and/or other securities so withdrawn shall also be
withdrawn from registration, and such Registrable Securities shall not be
transferred in a public distribution prior to one hundred eighty (180) days
after the effective date of such registration, or such other shorter period of
time as the underwriters may require.

     4.2 Company Registration.

     (a) Notice of Registration. If at any time or from time to time the Company
shall determine to register any of its securities, either for its own account or
the account of a security holder or holders, other than (i) a registration with
respect to securities issued or to be issued in an employee benefit plan or
other similar plan or agreement, (ii) a registration relating solely to a
transaction described in Rule 145, (iii) a registration on any form which does
not permit registration of securities of the Company for secondary sales or (iv)
a registration pursuant to Section 4.1 hereof, the Company will:

          (i) promptly give to each Holder the Registration Notice; 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 Securities specified in a written request or
     requests, made within ten (10) days after receipt of the Registration
     Notice from the Company, by any Holder.

     (b) Underwriting. If the registration described in the Registration Notice
is a registered public offering involving an underwriting, the Company shall so
advise the Holders as a part of the Registration Notice. In such event, the
right of any Holder to registration pursuant to Section 4.2 shall be conditioned
upon such

                                      B-51
<PAGE>   98

Holder's participation in such underwriting and the inclusion of Registrable
Securities in the underwriting to the extent provided herein. All Holders
proposing to distribute their securities through such underwriting shall
(together with the Company) enter into an underwriting agreement in customary
form with the managing underwriter selected for such underwriting by the
Company. Notwithstanding any other provision of this Section 4.2, if the
managing underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten and all shares of any other selling
stockholders (other than Holders of Registrable Securities) have first been
excluded from such registration, the managing underwriter may limit the
Registrable Securities and other securities to be distributed through such
underwriting; provided, however, that (i) no such reduction shall reduce the
number of Registrable Securities (other than Series E Registrable Securities and
Novation Registrable Securities) included in the registration below fifteen
percent (15%) of the total amount of securities included in such registration
("AVAILABLE 15% SHARES"); (ii) no such reduction shall reduce the number of
shares of Series E Registrable Securities included in the registration below
twelve percent (12%) of the total amount of securities included in such
registration ("AVAILABLE SERIES E SHARES"); and (iii) no such reduction shall
reduce the number of shares of Novation Registrable Securities held by VHA and
UHC, respectively, included in such registration below fifteen percent (15%) (in
the case of VHA) and five percent (5%) (in the case of UHC) of the total amount
of securities included in such registration in the case of the first and second
such underwritten offerings after the issuance of the Novation Registrable
Securities or reduce the number of shares of Novation Registrable Securities
below nine and one-half percent (9.5%) (in the case of VHA) and three and
one-half percent (3.5%) (in the case of UHC) of the total number of securities
included in any subsequent registration ("AVAILABLE NOVATION SHARES"), provided,
further that for purposes of allocating the number of Registrable Securities
(other than Series E Registrable Securities and Novation Registrable Securities)
that may be included in the aggregate number of Registrable Securities (other
than Series E Registrable Securities and Novation Registrable Securities)
constituting the Available 15% Shares, the registration and underwriting shall
be allocated such that each Holder is allowed to include in the registration and
underwriting the portion of the Available 15% Shares as is equal to (x) the
number of Registrable Securities (other than Series E Registrable Securities and
Novation Registrable Securities) which such Holder timely proposed to include in
such registration divided by (y) the number of Registrable Securities (other
than Series E Registrable Securities and Novation Registrable Securities) which
all Holders thereof timely proposed to include in such registration; provided,
further that for purposes of allocating the number of shares of Series E
Registrable Securities that may be included in the aggregate number of shares of
Series E Registrable Securities constituting the Available Series E Shares, the
registration and underwriting shall be allocated such that each Holder is
allowed to include in the registration and underwriting the portion of the
Available Series E Shares that is equal to (x) the number of shares of Series E
Registrable Securities which such Holder timely proposed to include in such
registration divided by (y) the number of Series E Registrable Securities which
all Holders thereof timely proposed to include in such registration; provided,
further that for purposes of allocating the number of Novation Registrable
Securities that may be included in the aggregate number of shares of Novation
Registrable Securities constituting the Available Novation Shares, the
registration and the underwriting shall be allocated such that each Holder is
allowed to include the portion of Available Novation Shares that is equal to (x)
the number of shares of Novation Registrable Securities which such Holder timely
proposed to include in such registration divided by (y) the number of Novation
Registrable Securities which all Holders thereof timely proposed to include in
such registration. The Company shall so advise all Holders distributing their
securities through such underwriting of such limitation and the number of
Registrable Securities that may be included in the registration and underwriting
shall be allocated to individual Holders timely requesting participation in such
registration under Section 4.2(a), (i) so that, as nearly as practicable, the
participation of each such Holder in the number of shares made available to the
Holders by the underwriters is, subject to the preceding sentence, in proportion
to (x) the number of Registrable Securities which such Holder timely proposed to
include in such registration to (y) the number of Registrable Securities which
all Holders timely proposed to include in such registration, or (ii) in such
other manner as shall be agreed to by the Company and such Holders of the
Registrable Securities proposed to be included in such registration; provided,
however, that the number of Registrable Securities to be included in such
underwriting shall not be reduced unless all other securities subject to
registration rights are first entirely excluded from such underwriting. No
Registrable Securities excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such
                                      B-52
<PAGE>   99

registration. To facilitate the allocation of shares in accordance with the
above provisions, the Company or the underwriters may round the number of shares
allocated to any Holder to the nearest 100 shares.

     If any Holder disapproves of the terms of any such underwriting, such
Holder may elect to withdraw therefrom by written notice to the Company and the
managing underwriter. Any Registrable Securities and/or other 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 (180) days after the effective date of such registration, or such
other shorter period of time as the underwriters may require.

     (c) Right to Terminate Registration. The Company shall have the right to
terminate or withdraw any registration initiated by it under this Section 4.2
prior to the effectiveness of such registration whether or not any Holder has
elected to include securities in such registration. The Registration Expenses of
such withdrawn registration shall be borne by the Company in accordance with
Section 4.4 hereof.

     4.3 Registration on Form S-3.

     (a) If the holders of at least one percent (1%) of the Registrable
Securities then outstanding or any holder of Series E Registrable Securities or
any holder of Novation Registrable Securities shall request that the Company
file a registration statement on Form S-3 (or any successor form to Form S-3 or
any similar short form registration statement), for a public offering of
Registrable Securities, the reasonably anticipated aggregate price to the public
of which would equal or exceed $1,000,000 and the Company is a registrant
entitled to use Form S-3 to register the Registrable Securities for such an
offering (or such successor or similar form), the Company shall use its best
efforts to cause such Registrable Securities to be registered on such form for
the offering and to cause such Registrable Securities to be qualified in such
jurisdictions as the Holder or Holders may reasonably request; provided,
however, that the Company shall not be required to effect more than one (1)
registration (which has been declared effective) pursuant to this Section 4.3 in
any twelve (12) month period for each of the Holders of the Registrable
Securities, the Series E Registrable Securities, and the Novation Registrable
Securities held by UHC, respectively, and the Company shall not be required to
effect more than two (2) registrations (which have been declared effective)
pursuant to this Section 4.3 in any twelve (12) month period for the Holders of
the Novation Registrable Securities held by VHA. The provisions of Section
4.1(b) shall be applicable to each registration initiated under this Section
4.3.

     (b) Notwithstanding the foregoing, the Company shall not be obligated to
take any action pursuant to this Section 4.3: (i) in any particular jurisdiction
in which the Company would be required to qualify to do business or execute a
general consent to service of process in effecting such registration,
qualification or compliance; (ii) if the Company, within ten (10) days of the
receipt of the request of the initiating Holders, gives notice of its bona fide
intention to effect the filing of a registration statement with the Commission
within ninety (90) days of receipt of such request (other than with respect to a
registration statement relating to a Rule 145 transaction, or an offering with
respect to securities issue are issuable under an employee benefit plan or other
similar plan or agreement); (iii) during the period starting with the date
ninety (90) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following, the effective date of any
registration statement pertaining to securities of the Company (other than a
registration of securities in a Rule 145 transaction or with respect to
securities issued or issuable with respect to an employee benefit plan or
similar plan or arrangement), provided that the Company is actively employing in
good faith all reasonable efforts to cause such registration statement to become
effective; or (iv) if the Company shall furnish to such Holder a certificate
signed by the President of the Company stating that in the good faith judgment
of the Board of Directors it would be seriously detrimental to the Company or
its stockholders for registration statements to be filed in the near future,
then the Company's obligation to use its best efforts to file a registration
statement shall be deferred for a period not to exceed ninety (90) days from the
receipt of the request to file such registration by such Holder; provided,
however, that the Company shall not exercise such right more than once in any
twelve (12) month period.

     4.4 Expenses of Registration. All Registration Expenses incurred in
connection with all registrations pursuant to Section 4.2, in connection with
all demand registrations under Section 4.1, and in connection with the first
three (3) S-3 registrations under Section 4.3 by each of the Series E
Registrable Securities and the Novation Registrable Securities, respectively,
shall be borne by the Company. All Selling Expenses relating to
                                      B-53
<PAGE>   100

securities registered on behalf of the Holders shall be borne by the holders of
securities included in such registration pro rata with the Company and among
each other on the basis of the number of shares so registered. Notwithstanding
the foregoing sentence, if a registration proceeding begun pursuant to Section
4.1 or 4.3 is subsequently withdrawn by the Holders, either (a) if Holders of
all of the Registrable Securities to have been registered agree, then the
Holders of the Registrable Securities to have been registered shall bear all
such Registration Expenses pro rata on the basis of the number of shares to have
been registered, or (b) if all such Holders do not agree, then the Initiating
Holders will forfeit their right to one registration pursuant to such section,
and the Company shall bear such Registration Expenses. Notwithstanding the
foregoing, however, if at the time of the withdrawal, the Holders have learned
of a material adverse change in the condition, business or prospects of the
Company from that known to the Initiating Holders at the time of their request,
of which the Company had received notice prior to the time of the request, then
the Holders shall not be required to pay any of said Registration Expenses or to
forfeit the right to one demand registration or S-3 registration, as the case
may be, and the Company shall pay the same.

     4.5 Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Section 4,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will:

          (a) Prepare and file with the Commission a registration statement with
     respect to such securities and use its best efforts to cause such
     registration statement to become and remain effective for at least one
     hundred eighty (180) days or until the earlier time that the distribution
     described in the Registration Statement has been completed, provided that
     before filing a registration statement or prospectus or any amendments or
     supplements thereto, the Company will furnish to the counsel selected by
     the holders of a majority of the Registrable Securities covered by such
     registration statement copies of all such documents proposed to be filed,
     which documents will be subject to the review of such counsel;

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

          (c) Furnish to the Holders participating in such registration and to
     the underwriters of the securities being registered such reasonable number
     of copies of the registration statement, preliminary prospectus, final
     prospectus and such other documents as such underwriters may reasonably
     request in order to facilitate the public offering of such securities.

          (d) Furnish, at the request of any Holder requesting registration of
     Registrable Securities on the date such Registrable Securities are
     delivered to the underwriters for sale in connection with a registration
     pursuant to this Section 4, (i) an opinion, dated such date, of counsel
     representing the Company for the purposes of such registration, in form and
     substance as is customarily given to underwriters in an underwritten public
     offering, addressed to the underwriters, if any, and to the Holders
     requesting registration of Registrable Securities and (ii) a letter dated
     such date, from the independent accountants of the Company, in form and
     substance as is customarily given by independent accountants to
     underwriters in an underwritten public offering, addressed to the
     underwriters, if any, and to the Holders requesting registration of
     Registrable Securities.

          (e) Use its best efforts to register and qualify the securities
     covered by such registration statement under such other securities or Blue
     Sky laws of such U.S. jurisdiction as shall be reasonably requested by the
     Holders, provided that the Company shall not be required in connection
     therein or as a condition thereto to qualify to do business or to file a
     general consent to service of process in any such states or jurisdictions.

          (f) In the event of any underwritten public offering, enter into and
     perform its obligations under an underwriting agreement, in usual and
     customary form, with the managing underwriter of such offering.

                                      B-54
<PAGE>   101

          (g) Notify each Holder 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 in the light of the
     circumstances then existing.

          (h) Cause all such Registrable Securities registered pursuant
     hereunder to be listed on each securities exchange on which similar
     securities issued by the Company are then listed and to be qualified for
     trading on each system on which similar securities issued by the Company
     are from time to time qualified.

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

          (j) make available for inspection by any underwriter participating in
     any disposition pursuant to such registration statement and any attorney,
     accountant or other agent retained by any such underwriter, all financial
     and other records, pertinent corporate documents and properties of the
     Company, and cause the Company's officers, directors, employees and
     independent accountants to supply all information reasonably requested by
     any such underwriter, attorney, accountant or agent in connection with such
     registration statement;

          (k) otherwise use its best efforts to comply with all applicable rules
     and regulations of the Securities and Exchange Commission, and make
     available to its security holders, as soon as reasonably practicable, an
     earnings statement covering the period of at least twelve months beginning
     with the first day of the Company's first full calendar quarter after the
     effective date of the registration statement, which earnings statement
     shall satisfy the provisions of Section 11(a) of the Securities Act and
     Rule 158 thereunder;

          (l) permit any holder of Registrable Securities that might be deemed,
     in the sole and exclusive judgment of such holder, to be an underwriter or
     a controlling person of the Company, to participate in the preparation of
     such registration or comparable statement and to require the insertion
     therein of material, furnished to the Company in writing, that in the
     reasonable judgment of such holder and its counsel and the Company's
     counsel should be included; and

          (m) in the event of the issuance of any stop order suspending the
     effectiveness of a registration statement, or of any order suspending or
     preventing the use of any related prospectus or suspending the
     qualification of any Registrable Securities included in such registration
     statement for sale in any jurisdiction, the Company will use its reasonable
     efforts promptly to obtain the withdrawal of such order.

If any such registration or comparable statement refers to any holder by name or
otherwise as the holder of any securities of the Company and if, in the sole and
exclusive judgment of such holder, such holder is or might be deemed to be a
controlling person of the Company, such holder shall have the right to require
(a) the inclusion in such registration statement of language, in form and
substance reasonably satisfactory to such holder, to the effect that the holding
of such securities by such holder is not to be construed as a recommendation by
such holder of the investment quality of the Company's securities covered
thereby and that such holding does not imply that such holder will assist in
meeting any future financial requirements of the Company, or (b) in the event
that such reference to such holder by name or otherwise is not required by the
Securities Act or any similar federal statute then in force, the deletion of the
reference to such holder.

     4.6 Indemnification.

     (a) The Company will indemnify each Holder, each of its officers,
directors, partners and legal counsel, and each person controlling such Holder
within the meaning of Section 15 of the Securities Act and 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),

                                      B-55
<PAGE>   102

including any of the foregoing incurred in settlement of any litigation,
commenced or threatened, arising out of or based on any of the following (each a
"VIOLATION"):

          (i) any untrue statement (or alleged untrue statement) of a material
     fact contained in any registration statement, prospectus, offering circular
     or other document, or any amendment or supplement thereto, incident to any
     such registration, qualification or compliance, or

          (ii) any omission (or alleged omission) to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein, in light of the circumstances in which they were made, not
     misleading, or

          (iii) any violation or alleged violation by the Company of the
     Securities Act, the Exchange Act or any federal or state law applicable to
     the Company in connection with any such registration, qualification or
     compliance;

and the Company will reimburse each such Holder, each of its officers,
directors, partners, and legal counsel and each person controlling 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 expense claim, loss, damage,
liability or action, provided that the Company will not be liable in any such
case to the extent that any such claim, loss, damage, liability or action 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 the Company by an instrument duly executed by such
Holder, controlling person or underwriter and stated to be specifically for use
therein, and provided further, that the indemnity agreement contained in this
Section 4.6(a) shall not apply to amounts paid in settlement of any such
expense, claim, loss, damage, liability or action if such settlement is effected
without the consent of the Company, which consent shall not be unreasonably
withheld.

     (b) Each Holder 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 the Company, each of its directors,
officers, and legal counsel, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company within the meaning of Section 15 of the Securities Act, and each
other Holder, each of its officers, directors, partners and legal counsel and
each person controlling such Holder within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages and liabilities
(or actions in respect thereof) arising out of or based on any Violation that is
contained in written information furnished to the Company by an instrument duly
executed by such Holder and stated to be specifically for use in such
registration, and will reimburse the Company, such Holders, 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 expense, claim, loss, damage, liability or action. Notwithstanding the
foregoing, the liability of each Holder under this Section 4.6(b) shall be
limited in an amount equal to the net proceeds received by such Holder of
Registrable Securities sold as contemplated herein, provided, however, that the
indemnity agreement contained in this Section 4.6(b) shall not apply to amounts
paid in settlement of any such expense loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld.

     (c) Each party entitled to indemnification under this Section 4.6 (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 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 unless the failure to give such notice
is materially prejudicial to an Indemnifying Party's ability to defend such
action, and provided, further, that the Indemnifying Party shall not assume the
defense for matters as to which there is a conflict of interest or as to which
such parties assert separate and different defenses but shall bear the expense
of such defense nevertheless.
                                      B-56
<PAGE>   103

     (d) If the indemnification provided for in this Section 4.6 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any expense, loss, liability, claim, damage, or action referred to
therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified
Party hereunder, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such expense, loss, liability, claim, damage,
or action in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party on the one hand and of the Indemnified Party on the other
in connection with the statements or omissions that resulted in such expense,
loss, liability, claim, damage, or action as well as any other relevant
equitable considerations. The relative fault of the Indemnifying Party and of
the Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party and the parties' relative intent,
knowledge and access to information. Notwithstanding the foregoing, in no event
shall the contribution by a Holder under this Section 4.6(d) exceed the net
proceeds from the offering received by such Holder, unless such Holder's
liability resulted from willful misconduct by such Holder and no person guilty
of fraudulent misrepresentation under Section 11(f) of the Securities Act shall
be entitled to contribution from a person who was not guilty of such fraudulent
misrepresentation.

     (e) The obligations of the Company and Holders under this Section 4.6 shall
survive the completion of any offering of Registrable Securities in a
registration statement under this Section 4, and otherwise.

     4.7 Information by Holder. The Holder or Holders of Registrable Securities
included in any registration shall furnish to the Company such information
regarding such Holder or Holders, the Registrable Securities held by them and
the distribution proposed by such Holder or Holders as shall be required in
connection with any registration, qualification or compliance referred to in
this Section 4.

     4.8 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 Restricted Securities, and the Novation Registrable Securities, to
the public without registration, the Company agrees to use its 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 the Company under the Securities Act and the Exchange
     Act;

          (c) Furnish to the Investor, so long as such Investor owns any
     Restricted Securities or Novation Registrable Securities, forthwith upon
     request a written statement by the Company as to its compliance with the
     reporting requirements of said Rule 144 and of the Securities Act and the
     Exchange Act, a copy of the most recent annual or quarterly report of the
     Company, and such other reports and documents of the Company and other
     information in the possession of or reasonably obtainable by the Company as
     an Investor may reasonably request in availing itself of any rule or
     regulation of the Commission allowing an Investor to sell any such
     securities without registration.

          (d) Take such actions as are necessary to enable the Holders to
     utilize Form S-3 pursuant to Section 4.3 for the sale of Registrable
     Securities.

     4.9 Transfer of Registration Rights. The rights to cause the Company to
register securities granted Holders under Sections 4.1, 4.2 and 4.3 may be
assigned by a Holder to (i) a transferee or assignee who acquires at least (or
after such transfer will hold an aggregate of) 250,000 Registrable Securities
(or 215,000 shares of Series E Registrable Securities or Novation Registrable
Securities), (ii) another Holder of Registrable Securities who already possesses
registration rights, (iii) a transferee or assignee of Registrable Securities
acquiring 10% or more of the outstanding stock of the Company, (iv) a transferee
of Registrable Securities which is a subsidiary, parent, partner, limited
partner, retired partner, shareholder or Affiliate of a Holder; (v) to a
transferee of Registrable Securities who is a Holder's family member or which is
a trust for the benefit of such Holder or (vi) in the case of Novation
Registrable Securities, patrons, affiliates, members, shareholders, partners or
controlled facilities of a shareholder, partner or member, of VHA or UHC;
provided, however, the Company is, within a reasonable time after such transfer,
furnished with written notice of the
                                      B-57
<PAGE>   104

name and address of such transferee or assignee and the securities with respect
to which such registration rights are being assigned; and provided, further,
that such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act.

     4.10 [Intentionally Omitted]

     4.11 Termination of Registration Rights. No Holder shall be entitled to
exercise any right provided for in this Section 4 after the earlier of (i)
September 30, 2005; or (ii) the time when all Registrable Securities held by
such Holder can, in the opinion of counsel to the Company, be sold by a Holder
in a three-month period without registration under the Securities Act pursuant
to Rule 144.

     4.12 No Inconsistent Agreements. The Company will not hereafter enter into
any agreement with respect to its securities that grants registration rights
that are inconsistent with or violate the rights granted to the holders of
Registrable Securities in this Agreement. Notwithstanding anything to the
contrary herein, the Company may grant registration rights in connection with
bank financings, lease lines, corporate partnering transactions, business
acquisitions of or by the Company or to entities with which the Company has a
business relationship, provided (a) such grant is not motivated primarily by
equity financing needs and (b) such grant is approved by the Board of Directors
(with the director appointed by the Series E Registrable Securities concurring
in the case of any change to the rights that are specific to the Series E
Registrable Securities, and with the director appointed from either Novation or
VHA concurring in the case of any change to the rights that are specific to the
Novation Registrable Securities). Persons granted registration rights pursuant
to the preceding sentence may become parties to part 4 of this Agreement with
the consent of the Company.

     4.13 Adjustments Affecting Registrable Securities. The Company will not
take any action, or permit any change to occur, with respect to its securities
for the purpose of materially and adversely affecting the ability of the holders
of Registrable Securities to include such Registrable Securities in a
registration undertaken pursuant to this Agreement, provided that this Section
4.13 shall not apply to actions or changes with respect to the Company's
business, balance sheet, earnings or revenue or with respect to equity, debt or
acquisition transactions involving the Company.

     5. [Intentionally Omitted]

     6. [Intentionally Omitted]

     7.1 Amendment and Waiver. Any term of this Agreement may be amended and the
observance of any term of this Agreement may be waived (either generally or in a

Novation Registrable Securities, the Holders of a majority of the Novation

amendments may be made without the approval of all parties hereto. Any amendment
or waiver effected in accordance with this Section 7.1 shall be binding upon
each holder of any Registrable Securities at the time outstanding, each future
holder of all such securities and the Company.

     7.2 Governing Law. This Agreement shall be governed by and construed under
the laws of the State of Delaware without reference to choice of law provisions
thereof. In connection with any litigation under this Agreement, the parties
hereto waive any right they may otherwise have to request trial by jury.

     7.3 Successors and Assigns. Except as otherwise expressly provided, the
provisions of this Agreement shall inure to the benefit of, and be binding upon,
the successors, assigns, heirs, executors and administrators of the parties.

<PAGE>   105

     7.4 Severability. In case any provision of this Agreement becomes or is
declared by a court of competent jurisdiction to be unenforceable, this
Agreement shall continue in full force and effect without said provision;
provided, however, that no such severability shall be effective if it materially
changes the economic benefit of this Agreement to any party.

     7.5 Notices. All notices and other communications required or permitted
hereunder shall be in writing and shall be deemed effectively given upon (a)
personal delivery or (b) one business day after transmission by facsimile to the
other party to be notified with confirmation of receipt or deposit with a
nationally recognized overnight courier, or (c) three business days after
deposit with the United States Post Office, by first class mail, postage
prepaid, addressed: (i) if to the Investors, at the Investors' address as set
forth on Exhibit A or Exhibit B hereto, or at such other address as the
Investors shall have furnished to the Company in writing, or (ii) if to the
Company, at its current address or at such other address as the Company shall
have furnished to the Investors in writing.

     7.6 Counterparts. This Agreement may be executed in any number of
counterparts, each of which is an original, and all of which together shall
constitute one instrument.

     7.7 Reorganization. The provisions of this Agreement shall apply to any
shares or other securities resulting from any stock split or reverse split,
stock dividend, reclassification, subdivision, consolidation or reorganization
of any shares or other equity securities of the Company and to any shares or
other securities of the Company or of any successor company that may be received
by any of the parties hereto by virtue of their respective ownership of any
shares of Common Stock of the Company.

     7.8 Remedies. Any Person having rights under any provision of this
Agreement will be entitled to enforce such rights specifically and to recover
damages caused by reason of any breach of any provision of this Agreement and to
exercise all other rights granted by law. 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 (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce or prevent violation of the provisions of this
Agreement.

     7.9 Further Assurances. Each party to this Agreement hereby covenants and
agrees, without the necessity of any further consideration, to execute and
deliver any and all such further documents and take any and all such other
actions as may be reasonably necessary or appropriate to carry out the intent
and purposes of this Agreement and to consummate the transactions contemplated
hereby.

     7.10 Entire Agreement. This Agreement constitutes the entire agreement of
the parties concerning the subject matter hereof and supersedes the Second
Rights Agreement and the registration rights previously granted by the Company
to the Pharos Investors and the USL Investors, each of which is hereby
terminated as of the date of this Agreement.

other document issued, filed with, or recorded by any Governmental Entity.

          (a) No material Parent Intellectual Property or product or service of
     Parent is subject to any proceeding, agreement, or stipulation to which
     Parent is a party, or any outstanding decree, order or judgment, which
     arose out of any proceeding to which Parent was either a party or of which
     Parent has knowledge, restricting in any manner the use, transfer, or
     licensing thereof by Parent, or which may affect the validity, use or
     enforceability of such Parent Intellectual Property.

          (b) Each material item of Parent Registered Intellectual Property is

     fees currently due in connection with such Parent Registered Intellectual
     Property have been made and all necessary documents, recordations and
     certificates in connection with such Parent Registered Intellectual
     Property have been filed with the relevant patent, copyright, trademark or
     other authorities in the United States or foreign jurisdictions, as the
     case may be, for the purposes of maintaining such Parent Registered
     Intellectual Property, except, in each case, as would not materially

     restrictions).

          (d) Neither Parent nor any of its subsidiaries has transferred
     ownership of, or granted any exclusive license with respect to, any
     Intellectual Property that is or was material Parent Intellectual Property,
     to any third party.

          (e) Part 3.9(e) of the Parent Disclosure Letter lists all material
     contracts, licenses and agreements to which Parent is a party (i) pursuant
     to which any exclusive rights with respect to Parent Intellectual Property

     to which a third party has licensed, transferred, sold or distributed any
     material Intellectual Property to Parent.

     practices under the laws of any jurisdiction.

          (g) Parent has not received written notice from any third party that
     the operation of the business of Parent or any act, product or service of
     Parent, infringes or misappropriates the Intellectual Property of any third
     party or constitutes unfair competition or trade practices under the laws
     of any jurisdiction, which allegation, if true, would have a Material
     Adverse Effect on Parent.

          (h) To the knowledge of Parent, no person has or is infringing or
     misappropriating any Parent Intellectual Property, which infringement or
     misappropriation, individually or in the aggregate, would have a Material
     Adverse Effect on Parent.

          (i) Parent and its subsidiaries have taken reasonable steps to protect
     Parent's and its subsidiaries' rights in Parent's and such subsidiaries'
     confidential information and trade secrets, except where the failure to do
     so would not have a Material Adverse Effect on Parent.

          (j) None of the Parent Intellectual Property or product or service of
     Parent contains any defect in connection with processing data containing
     dates in leap years or in the year 2000 or any preceding or following

on Parent. To Parent's knowledge, no investigation or review by any Governmental
Entity is pending or has been threatened in a writing delivered to Parent
against Parent or any of its subsidiaries. There is no agreement with any
Governmental Entity, judgment, injunction, order or decree binding upon Parent

Parent or any of its subsidiaries.

     (b) Parent and its subsidiaries hold all permits, licenses, exemptions,
orders and approvals from governmental authorities that are material to or
required for the operation of the business of Parent as currently conducted
(collectively, the "PARENT PERMITS"), and are in compliance with the terms of
the Parent Permits, except where the failure to hold such Parent Permits, or be
in such compliance, would not, individually or in the aggregate, have a Material
Adverse Effect on Parent.

pending or, to the knowledge of Parent, threatened against, relating to or
affecting Parent or any of its subsidiaries, before any Governmental Entity or

expected, either singularly or in the aggregate with all such claims, actions or
proceedings, to have a Material Adverse Effect on Parent following the
transactions contemplated hereby or have a material adverse effect on the
ability of the parties hereto to consummate the transactions contemplated
hereby.

has been established, maintained and administered in material compliance with
its terms and conditions and with the requirements prescribed by any and all
statutory or regulatory laws that are applicable to such International Parent
Employee Plan. Furthermore, no International Parent Employee Plan has unfunded
liabilities, that as of the

                                      C-11
<PAGE>   118

law, no condition exists that would prevent Parent from terminating or amending
any International Parent Employee Plan at any time for any reason.

owned its properties or leased, owned or operated any facilities, there have
been no disposals, releases or threatened releases of Hazardous Materials (as
defined below) on, from or under any such properties or facilities that would
have a Material Adverse Effect on Parent. Parent has no knowledge of any
presence, disposals, releases or threatened releases of Hazardous Materials on,
from or under any of such properties or facilities, which may have occurred
prior to Parent or any of its subsidiaries having taken possession of any of
such properties or facilities which might reasonably be expected to have a
Material Adverse Effect on Parent. None of the properties or facilities
currently leased or owned by Parent or any of its subsidiaries or any properties
or facilities previously leased or owned by Parent or any of its subsidiaries is
in violation of any federal, state or local law, ordinance, regulation or order
relating to industrial hygiene or to the environmental conditions on, under or
about such properties or facilities, including, but not limited to, soil and
ground water condition which violation would have a Material Adverse Effect on
Parent. During Parent's occupancy of any properties or facilities owned or
leased at any time by Parent, neither Parent, nor to Parent's knowledge, any
third party, has used, generated, manufactured, released or stored on, under or
about such properties and facilities or transported to or from such properties
and facilities any Hazardous Materials that would have or is reasonably likely
to have a Material Adverse Effect on Parent. During the time that Parent or any
of its subsidiaries has owned or leased the properties and facilities currently
occupied by it or any properties and facilities previously occupied by Parent or
any of its subsidiaries, there has been no material litigation, proceeding or
administrative action brought or threatened against Parent or any of its
subsidiaries, or any material settlement reached by Parent or any of its
subsidiaries with, any party or parties alleging the presence, disposal, release
or threatened release of any Hazardous Materials on, from or under any of such
properties or facilities.

     For purposes of this Agreement, the terms "DISPOSAL," "RELEASE," and
"THREATENED RELEASE" have the definitions assigned thereto by the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, 42 U.S.C. sec.

which is or becomes prior to the Closing Date, regulated under, or defined as a
"hazardous substance," "pollutant," "contaminant," "toxic chemical," "hazardous

     of Parent's Board of Directors, other than those that are terminable by
     Parent or any of its subsidiaries on no more than thirty days notice

pursuant to clauses (a) through (g) above or pursuant to Section 3.9 or filed
with any Parent SEC Report ("PARENT CONTRACTS") are valid and in full force and
effect, except to the extent that such invalidity would not have a Material

breach of or constitute a default (or an event that with notice or lapse of time
or both would become a default) under, or impair UHC's rights or alter the
rights or obligations of any third party under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of an Encumbrance on any of the properties or assets of UHC pursuant
to, any note, bond, mortgage, indenture, contract, agreement, lease, license,
permit, franchise or other instrument or obligation to which UHC is a party or
by which UHC or any of its properties are bound or affected, except, in the case
of clauses (ii) and (iii), for such conflicts, violations, breaches, defaults,
impairments, or rights which, individually or in the aggregate, would not have a
Material Adverse Effect on UHC. Except as set forth in a letter delivered by UHC
to Parent concurrently with the execution of this Agreement, no consents,
waivers and approvals under any of UHC's or any of its subsidiaries' agreements,
contracts, licenses or leases are required to be obtained in connection with the
consummation of the transactions contemplated hereby, which, if individually or
in the aggregate not obtained, would have a Material Adverse Effect on UHC.

<PAGE>   121

     (c) No consent, approval, order or authorization of, or registration,
declaration or filing with any Governmental Entity is required to be obtained or
made by UHC in connection with the execution and delivery of this Agreement or
the Outsourcing Agreement or the consummation of the transactions contemplated
hereby or thereby, except for (i) such consents, approvals, orders,
authorizations, registrations, declarations and filings as may be required under
applicable federal, foreign and state securities (or related) laws and the HSR
Act and the securities or antitrust laws of any foreign country, and (ii) such
other consents, authorizations, filings, approvals and registrations which if
not obtained or made would not have a Material Adverse Effect on UHC or have a
material adverse effect on the ability of the parties hereto to consummate the
transactions contemplated hereby.

     4.3 Acquisition for Own Account.  The Shares, Warrant and Warrant Stock to
be delivered to UHC hereunder will be acquired for UHC's own account, not as a
nominee or agent, and not with a view to the public resale or distribution
thereof within the meaning of the 1933 Act, and UHC represents that it has no
present intention or agreement to sell, grant any participation in, or otherwise
distribute any of the Shares, Warrant or Warrant Stock to be acquired by UHC
hereunder in any public resale or distribution within the meaning of the 1933
Act. UHC also represents that it has not been formed for the specific purpose of
acquiring the Shares, Warrant or Warrant Stock under this Agreement.

     4.4 Disclosure of Information.  UHC believes it has received or has had
full access to all the information it considers necessary or appropriate to make
an informed ownership decision with respect to the Shares, Warrant and Warrant
Stock to be issued to UHC under this Agreement. UHC further has had an
opportunity to ask questions and receive answers from Parent regarding the terms
and conditions of the offering of the Shares, Warrant and Warrant Stock and to
obtain additional information (to the extent Parent possessed such information
or could acquire it without unreasonable effort or expense) necessary to verify
any information furnished to UHC or to which UHC had access. The foregoing,
however, does not in any way limit or modify the representations and warranties
made by Parent in Section 3.

     4.5 Experience.  UHC understands that ownership of the Shares, Warrant and
Warrant Stock involves substantial risk. UHC: (i) has experience as owner of
securities of companies in the development stage and acknowledges that UHC is
able to fend for itself, can bear the economic risk of UHC's ownership of the
Shares, Warrant and Warrant Stock and has such knowledge and experience in
financial or business matters that UHC is capable of evaluating the merits and
risks of this ownership of the Shares, Warrant and Warrant Stock and protecting
its own interests in connection with this ownership and/or (ii) has a
preexisting personal or business relationship with Parent and certain of its
officers, directors or controlling persons of a nature and duration that enables
UHC to be aware of the character, business acumen and financial circumstances of
such persons.

     4.6 Accredited Investor Status.  UHC is an "accredited investor" within the
meaning of Regulation D promulgated under the 1933 Act.

     4.7 Restricted Securities.  UHC understands that the Shares and the Warrant
are, and upon issuance under the Warrant, the Warrant Stock will be
characterized as "restricted securities" under the 1933 Act inasmuch as they are
being acquired from Parent in a transaction not involving a public offering and
that under the 1933 Act and applicable regulations thereunder such securities
may be resold without registration under the 1933 Act only in certain limited
circumstances. In this connection, UHC represents that UHC is familiar with Rule
144 of the SEC, as presently in effect, and understands the resale limitations
imposed thereby and by the 1933 Act.

     4.8 No Solicitation.  At no time was UHC presented with or solicited by any
publicly issued or circulated newspaper, mail, radio, television or other form
of general advertising or solicitation in connection with the issuance or
delivery of the Shares or the Warrant.

                                      C-15
<PAGE>   122

     4.9 Further Limitations on Disposition.  Without in any way limiting the
representations set forth above, UHC further agrees not to make any disposition
of all or any portion of the Shares or Warrant Stock or of any interest therein
to any person or entity unless:

          (a) there is then in effect a registration statement under the 1933
     Act covering such proposed disposition of Shares or Warrant Stock and such
     disposition is made in accordance with such registration statement; or

          (b) UHC shall have notified Parent of the proposed disposition of the
     Shares or the Warrant Stock and shall have furnished Parent with a
     statement of the circumstances surrounding such proposed disposition, and,
     at the expense of UHC or its transferee, with an opinion of counsel,
     reasonably satisfactory to Parent, that such disposition will not require
     registration of such securities under the 1933 Act.

UHC acknowledges that the Warrant is non-transferable to the extent it has not
vested.

     4.10 Legends.  UHC understands and agrees that the certificates evidencing
the Shares, the Warrant and the Warrant Stock will bear legends substantially
similar to those set forth below, as applicable, in addition to any other legend
that may be required by applicable law, by Parent's Certificate of Incorporation
or Bylaws, or by any agreement between Parent and UHC:

          (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE SECURITIES
     LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON
     TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS
     PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT
     TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY
     MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN
     INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN
     OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE
     EFFECT THAT ANY PROPOSED TRANSFER OTHERWISE PERMITTED UNDER CONTRACTUAL
     RESTRICTIONS ON RESALE APPLICABLE TO THESE SECURITIES IS IN COMPLIANCE WITH
     THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

          (b) THE SECURITIES REPRESENTED HEREBY MAY BE SUBJECT TO CERTAIN
     RESTRICTIONS ON VOTING AND THE HOLDERS HEREOF MAY BE BOUND BY CERTAIN
     RESTRICTIONS ON ACQUISITION OF THE ISSUER'S CAPITAL STOCK PURSUANT TO A
     COMMON STOCK AND WARRANT AGREEMENT BETWEEN THE ORIGINAL HOLDERS OF THESE
     SECURITIES AND THE ISSUER, A COPY OF WHICH MAY BE OBTAINED FROM THE ISSUER.

The legend set forth in (a) above shall be removed by Parent from any
certificate evidencing Shares or Warrant Stock upon delivery to Parent of an
opinion by counsel, reasonably satisfactory to Parent, to the effect that a
registration statement under the 1933 Act is at that time in effect with respect
to the legended security or to the effect that such security can be freely
transferred in a public sale without such a registration statement being in
effect and that such transfer will not jeopardize the exemption or exemptions
from registration pursuant to which Parent issued the Shares or Warrant Stock.
The legend set forth in (b) above shall be removed by Parent from any
certificate evidencing Shares or Warrant Stock upon delivery to Parent of
evidence that such Shares or Warrant Stock have been sold or transferred to a
person other than UHC.

     4.11 Disclosure.  The information supplied by UHC for inclusion or
incorporation by reference in the Proxy Statement shall not on the date the
Proxy Statement is mailed to Parent's stockholders, at the time of the Parent
Stockholders' Meeting or as of the Closing, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not false or misleading; or omit to
state any material fact necessary to correct any statement in any earlier
communication with respect to the solicitation of proxies for the Parent
Stockholders' Meeting which has become false or misleading. If at any time prior
to the Closing
                                      C-16
<PAGE>   123

any event relating to UHC or any of its affiliates, officers or directors should
be discovered by UHC which is required to be set forth in a supplement to the
Proxy Statement, UHC shall promptly inform Parent. Notwithstanding the
foregoing, UHC makes no representation or warranty with respect to any
information supplied by Parent which is contained in the Proxy Statement.

     4.12 Anti-Takeover Protections.  For the three years prior to the date of
this Agreement, none of UHC, its "affiliates" nor "associates" (as such terms
are defined in Section 203 of the Delaware Law) were the owner of 15% or more of
the outstanding voting stock of Parent. To UHC's knowledge, no other Takeover
Statute applies or purports to apply to this Agreement or the transactions
contemplated hereby.

                                   ARTICLE V

                          CONDUCT PRIOR TO THE CLOSING

Agreement and continuing until the earlier of the termination of this Agreement

business in compliance in all material respects with all applicable material
laws and regulations, pay its debts and taxes when due subject to good faith

practices and policies to (i) preserve intact its present business organization,
(ii) keep available the services of its present officers and employees and (iii)

     amend or modify in any material respect any rights to any Intellectual
     Property material to the business of Parent that is owned by, or
     exclusively licensed to, Parent or one of its subsidiaries, other than
     non-exclusive licenses, distribution agreements, advertising agreements, or
     other similar agreements in the ordinary course of business and consistent
     with past practice;

          (d) Declare, set aside or pay any dividends on or make any other
     distributions (whether in cash, stock, equity securities or property) in
     respect of any capital stock or split, combine or reclassify any capital
     stock or issue or authorize the issuance of any other securities in respect
     of, in lieu of or in substitution for any capital stock;

          (e) Purchase, redeem or otherwise acquire, directly or indirectly, any

     employment relationship with any employee pursuant to stock option or
     purchase agreements in effect on the date hereof;

          (f) Issue, deliver, sell, authorize, pledge or otherwise encumber any

                                      C-17
<PAGE>   124

     any shares of capital stock or any securities convertible into shares of
     capital stock, or enter into other agreements or commitments of any
     character obligating it to issue any such shares or convertible securities,
     other than the grant, issuance, delivery and/or sale of (i) shares of
     Common Stock pursuant to the exercise of Parent Options outstanding on the
     date of this Agreement, or granted in accordance with clause (iii) of this
     Section 5.1(f), (ii) shares of Common Stock issuable to participants in the
     Parent ESPP consistent with the terms thereof, (iii) Parent Options granted
     to existing employees and newly-hired employees in an aggregate amount not
     to exceed 2,000,000, none of which Parent Options shall provide for or
     permit any acceleration of the exercisability thereof in connection with
     any of the transactions contemplated by this Agreement, and (iv) shares of
     Common Stock issued in connection with acquisitions, joint ventures,
     strategic relationships or alliances, and commercial transactions permitted
     under Section 5.1(h) below;

          (g) Cause, permit or propose any amendments to its Certificate of
     Incorporation, Bylaws or other charter documents (or similar governing
     instruments of any of its subsidiaries), other than an amendment to its
     Certificate of Incorporation to increase the authorized number of shares of
     Common Stock;

          (h) Acquire or agree to acquire by merging or consolidating with, or
     by purchasing any equity interest in or a portion of the assets of, or by
     any other manner, any business or any corporation, partnership, association
     or other business organization or division thereof; or otherwise acquire or
     agree to acquire any assets which are material, individually or in the
     aggregate, to the business of Parent, or enter into any material joint
     ventures, strategic relationships or alliances, or enter into any
     commercial transaction involving the issuance or potential issuance of
     equity securities of Parent; provided, that Parent shall not be prohibited
     hereunder from (x) acquiring EquipMD, Inc. pursuant to the Agreement and
     Plan of Merger among Parent, Augustacorp, Inc. and EquipMD, Inc. (a true
     and complete copy of which has been made available to UHC) or (y) making or
     agreeing to make acquisitions, entering into joint ventures, strategic
     relationships or alliances, or entering into commercial transactions
     involving the issuance or potential issuance of Common Stock, all of which
     together do not involve the issuance or potential issuance of more than
     5,000,000 shares of Common Stock in the aggregate, and none of which
     acquisitions, joint ventures, strategic relationships, alliances,
     agreements or commercial transactions could reasonably be expected to
     materially delay the issuances of Common Stock and Warrant contemplated by
     this Agreement (Parent and UHC acknowledge that the fact that an
     acquisition would be deemed "significant" under Item 2 of Form 8-K under
     the 1934 Act does not necessarily mean that such acquisition could
     reasonably be expected to materially delay the issuances of Common Stock
     and the Warrant contemplated by this Agreement); provided, further, that
     Parent shall provide written notice to UHC prior to signing any agreement
     regarding any such acquisition or transaction;

          (i) Sell, lease, license, encumber (except in connection with actions
     permitted under Section 5.1(j)) or otherwise dispose of any properties or
     assets which are material, individually or in the aggregate, to the
     business of Parent;

          (j) Incur any indebtedness for borrowed money or guarantee any such
     indebtedness of another person, issue or sell any debt securities or
     options, warrants, calls or other rights to acquire any debt securities of
     Parent, enter into any "keep well" or other agreement to maintain any
     financial statement condition or enter into any arrangement having the
     economic effect of any of the foregoing other than (i) in connection with
     the financing of ordinary course trade payables consistent with past
     practice, (ii) pursuant to existing credit facilities in the ordinary
     course of business, (iii) equipment leasing arrangements or (iv) in
     aggregate amount not to exceed $1,000,000;

          (k) (i) Adopt or amend any employee benefit plan or employee stock
     purchase or employee stock option plan, or enter into any employment
     contract or collective bargaining agreement (other than offer letters and
     letter agreements entered into in the ordinary course of business
     consistent with past practice with employees who are terminable "at will")
     other than an increase in the number of shares of Common Stock reserved for
     issuance under Parent Stock Option Plans or Parent ESPP, or (ii) pay any
     special bonus or special remuneration to any director or employee, or
     increase the salaries or wage rates or fringe benefits (including rights to

<PAGE>   125

     past practice, or change in any material respect any management policies or
     procedures;

          (l) Make any capital expenditures outside of the ordinary course of

     agreement to which Parent or any subsidiary thereof is a party, or waive,
     release or assign any material rights or claims thereunder, except in the
     ordinary course of business;

          (n) Materially revalue any of its assets or, except as required by
     GAAP, make any change in accounting methods, principles or practices;

          (o) Initiate or settle any material litigation, arbitration, mediation
     or other legal proceeding;

          (p) Take or permit any action with the intent to directly or
     indirectly adversely impact any of the transactions contemplated by this
     Agreement; or

          (q) Agree in writing or otherwise to take any of the actions described
     in Section 5.1(a) through (p) above.

     5.2 Meeting of Parent Stockholders.

     (a) Promptly after the date hereof, Parent will take all action necessary
in accordance with the Delaware Law and its Certificate of Incorporation and
Bylaws to convene the Parent Stockholders' Meeting to be held as promptly as
practicable and in any event (to the extent permissible under applicable law)
within 45 days after the completion of the SEC's review of the Proxy Statement
for the purpose of voting upon the Parent Stockholder Approval. Subject to
Section 5.2(c), Parent will use its commercially reasonable efforts to solicit
from its stockholders proxies in favor of the approval of the Parent Stockholder
Approval and will take all other action necessary or advisable to secure the
vote or consent of its stockholders required by the rules of the Nasdaq Stock
Market, Delaware Law, its Certificate of Incorporation and Bylaws to obtain such
approval. Notwithstanding anything to the contrary contained in this Agreement,
Parent may adjourn or postpone the Parent Stockholders' Meeting to the extent
necessary to ensure that any necessary supplement or amendment to the Proxy
Statement is provided to Parent's stockholders in advance of a vote on the
Parent Stockholder Approval or, if as of the time for which Parent Stockholders'
Meeting is originally scheduled (as set forth in the Proxy Statement) there are
insufficient shares of Parent Common Stock represented (either in person or by
proxy) to constitute a quorum necessary to conduct the business of the Parent
Stockholders' Meeting. Parent shall ensure that the Parent Stockholders' Meeting
is called, noticed, convened, held and conducted, and that all proxies solicited
by Parent in connection with the Parent Stockholders' Meeting are solicited, in
compliance with the Delaware Law, its Certificate of Incorporation and Bylaws,
the rules of the Nasdaq Stock Market and all other applicable legal
requirements.

     (b) Subject to Section 5.2(c), the Board of Directors of Parent shall
recommend that Parent's stockholders approve the Parent Stockholder Approval at
the Parent Stockholders' Meeting; and the Proxy Statement shall include a
statement to the effect that the Board of Directors of Parent has recommended
that Parent's stockholders approve the Parent Stockholder Approval at the Parent
Stockholders' Meeting; and (iii) neither the Board of Directors of Parent nor
any committee thereof shall withdraw, amend or modify, or propose or resolve to
withdraw, amend or modify in a manner adverse to UHC, the recommendation of the
Board of Directors of Parent that Parent's stockholders approve the Parent
Stockholder Approval.

     (c) Nothing in this Agreement shall prevent the Board of Directors of
Parent from withholding, withdrawing, amending or modifying its recommendation
in favor of the Parent Stockholder Approval if (i) a Superior Offer (as defined
below) is made to Parent and is not withdrawn, (ii) Parent shall have provided
written notice to VHA and UHC (a "NOTICE OF SUPERIOR OFFER") advising them that
Parent has received a Superior Offer, specifying all of the material terms and
conditions of such Superior Offer and identifying the person or entity making
such Superior Offer, (iii) VHA and/or UHC shall not have, within three business
days of Parent's receipt of the Notice of Superior Offer, made an offer that
Parent's Board of Directors by a majority vote determines in its good faith
judgment (after consultation with a financial advisor of national
                                      C-19
<PAGE>   126

standing) to be at least as favorable to Parent's stockholders as such Superior
Offer (it being agreed that the Board of Directors of Parent shall convene a
meeting to consider any such offer by VHA and/or UHC promptly following the
receipt thereof), (iv) the Board of Directors of Parent concludes in good faith,
after consultation with its outside counsel, that, in light of such Superior
Offer, the withholding, withdrawal, amendment or modification of such
recommendation is required in order for the Board of Directors of Parent to
comply with its fiduciary obligations to Parent's stockholders under applicable
law and (v) Parent shall not have violated any of the restrictions set forth in
Section 5.4(a) or (b) or this Section 5.2. Parent shall provide UHC with at
least one day prior notice (or such lesser prior notice as provided to the
members of the Parent's Board of Directors) of any meeting of the Parent's Board
of Directors at which Parent's Board of Directors is reasonably expected to
consider any Parent Acquisition Proposal (as defined in Section 5.4) to
determine whether such Parent Acquisition Proposal is a Superior Offer. Nothing
contained in this Section 5.2(c) shall limit Parent's obligation to hold and
convene the Parent Stockholders' Meeting (regardless of whether the
recommendation of the Board of Directors of Parent shall have been withdrawn,
amended or modified).

     For purposes of this Agreement, "SUPERIOR OFFER" shall mean an unsolicited,
bona fide written offer made by a third party to consummate any of the following
transactions: (i) a merger or consolidation involving Parent pursuant to which
the stockholders of Parent immediately preceding such transaction hold less than
50% of the equity interest in the surviving or resulting entity of such
transaction or (ii) the acquisition by any person or group (including by way of
a tender offer or an exchange offer or a two step transaction involving a tender
offer followed with reasonable promptness by a merger involving Parent),
directly or indirectly, of ownership of 100% of the then outstanding shares of
capital stock of Parent, on terms that the Board of Directors of Parent
determines, in its reasonable judgment (after consultation with a financial
advisor of national standing) to be more favorable to Parent stockholders than
the terms of this Agreement and the VHA Agreement; provided, however, that any
such offer shall not be deemed to be a "Superior Offer" if any financing
required to consummate the transaction contemplated by such offer is not
committed and is not likely in the reasonable judgment of Parent's Board of
Directors (after consultation with its financial advisor) to be obtained by such
third party on a timely basis.

     (d) Nothing contained in this Agreement shall prohibit Parent or its Board
of Directors from taking and disclosing to its stockholders a position
contemplated by Rules 14d-9 and 14e-2(a) promulgated under the 1934 Act, or
otherwise required by applicable law.

     5.3 Proxy Statement; Antitrust Filings.

     (a) As promptly as practicable after the execution of this Agreement,
Parent will prepare and file with the SEC, the Proxy Statement. Parent will
respond to any comments of the SEC, and will cause the Proxy Statement to be
mailed to its stockholders, as promptly as practicable in compliance with
applicable law. Promptly after the date of this Agreement, if required, each of
UHC and Parent will prepare and file (i) with the United States Federal Trade
Commission and the Antitrust Division of the United States Department of Justice
Notification and Report Forms relating to the transactions contemplated herein
as required by the HSR Act, as well as comparable pre-merger notification forms
required by the merger notification or control laws and regulations of any
applicable jurisdiction, as agreed to by the parties (the "ANTITRUST FILINGS").
UHC and Parent each shall promptly supply the other with any information which
may be required in order to effectuate any filings pursuant to this Section 5.3.

     (b) Each of UHC and Parent will notify the other promptly upon the receipt
of any comments from the SEC or its staff or any other government officials in
connection with any filing made pursuant hereto and of any request by the SEC or
its staff or any other government officials for amendments or supplements to the
Proxy Statement or any Antitrust Filings or for additional information, and will
supply the other with copies of all correspondence between such party or any of
its representatives, on the one hand, and the SEC, or its staff or any other
government officials, on the other hand, with respect to the Proxy Statement or
any Antitrust Filing. Each of UHC and Parent will cause all documents that it is
responsible for filing with the SEC or other regulatory authorities under this
Section 5.3 to comply in all material respects with all applicable requirements
of law and the rules and regulations promulgated thereunder. Whenever any event
occurs which is required to be set forth in an amendment or supplement to the
Proxy Statement or any Antitrust Filing, UHC or Parent,

                                      C-20
<PAGE>   127

as the case may be, will promptly inform the other of such occurrence and
cooperate in filing with the SEC or its staff or any other government officials,
and/or mailing to stockholders of Parent, such amendment or supplement.

     5.4 No Solicitation.

     (a) From and after the date of this Agreement until the Closing or
termination of this Agreement pursuant to Article IX, Parent and its
subsidiaries will not, nor will they authorize or permit any of their respective
officers, directors, affiliates or employees or any investment banker, attorney
or other advisor or representative retained by any of them to, directly or
indirectly, (i) solicit, initiate, encourage or induce the making, submission or
announcement of any Parent Acquisition Proposal (as hereinafter defined), (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any non-public information with respect to, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes an
Parent Acquisition Proposal, (iii) engage in discussions with any person with
respect to any Parent Acquisition Proposal, except as to the existence of these
provisions, (iv) except as set forth in Section 5.2(c), approve, endorse or
recommend any Parent Acquisition Proposal or (v) enter into any letter of intent
or similar document or any contract, agreement or commitment contemplating or
otherwise relating to any Parent Acquisition Proposal; provided, however, that
prior to the approval of the Parent Stockholder Approval at the Parent
Stockholders' Meeting, Parent may furnish nonpublic information regarding Parent
and its subsidiaries to, or enter into discussions or negotiations with, any
person or group who has submitted (and not withdrawn) to Parent an unsolicited,
written, bona fide Parent Acquisition Proposal that the Board of Directors of
Parent reasonably concludes (after consultation with a financial advisor of
national standing) may constitute a Superior Offer if (1) neither Parent nor any
representative of Parent and its subsidiaries shall have violated any of the
restrictions set forth in this Section 5.4, (2) the Board of Directors of Parent
concludes in good faith, after consultation with its outside legal counsel, that
such action is required in order for the Board of Directors of Parent to comply
with its fiduciary obligations to Parent's stockholders under applicable law,
(3) 36 hours prior to furnishing any such nonpublic information to, or entering
into any such discussions with, such person or group, Parent gives VHA and UHC
written notice of the identity of such person or group and all of the material
terms and conditions of such Parent Acquisition Proposal and of Parent's
intention to furnish nonpublic information to, or enter into discussions with,
such person or group, and Parent receives from such person or group an executed
confidentiality agreement containing customary terms. Parent and its
subsidiaries will immediately cease any and all existing activities, discussions
or negotiations with any parties conducted heretofore with respect to any Parent
Acquisition Proposal. Without limiting the foregoing, it is understood that any
violation of the restrictions set forth in the preceding two sentences by any
officer, director or employee of Parent or any of its subsidiaries or any
investment banker, attorney or other advisor or representative of Parent or any
of its subsidiaries shall be deemed to be a breach of this Section 5.4(a) by
Parent.

     For purposes of this Agreement, "PARENT ACQUISITION PROPOSAL" shall mean
any offer or proposal relating to any transaction or series of related
transactions, other than the transactions contemplated by this Agreement (any
such transaction or series of related transactions, a "PARENT ACQUISITION"),
involving: (A) any acquisition or purchase from Parent by any person or "group"
(as defined under Section 13(d) of the 1934 Act and the rules and regulations
thereunder) of more than 50% of the outstanding voting securities of Parent or
any of its subsidiaries, or any tender offer or exchange offer that if
consummated would result in any person or "group" beneficially owning more than
50% of the outstanding voting securities of Parent or any of its subsidiaries,
or any merger, consolidation, business combination or similar transaction
involving Parent pursuant to which the stockholders of Parent immediately
preceding such transaction hold less than 50% of the equity interests in the
surviving or resulting entity of such transaction; or (B) any sale, exchange,
transfer, acquisition, or disposition of more than 50% of the assets of Parent.

     (b) In addition to the obligations of Parent set forth in paragraph (a) of
this Section 5.4, Parent as promptly as practicable shall advise VHA and UHC
orally and in writing of any request for non-public information or inquiry which
Parent reasonably believes would lead to a Parent Acquisition Proposal or of any
Parent Acquisition Proposal, the material terms and conditions of such request,
Parent Acquisition Proposal or inquiry, and the identity of the person or group
making any such request, Parent Acquisition Proposal or
                                      C-21

inquiry. Parent will keep VHA and UHC informed as promptly as practicable in all
material respects of the status and details (including material amendments or
proposed amendments) of any such request, Parent Acquisition Proposal or
inquiry.

     (c) From and after the date of this Agreement until the Closing or
termination of this Agreement pursuant to Article IX, UHC and its affiliates
will not, nor will they authorize or permit any of their respective officers,
directors, affiliates or employees or any investment banker, attorney or other
advisor or representative retained by any of them to, directly or indirectly,
(i) solicit, initiate, encourage or induce the making, submission or
announcement of any UHC Proposal (as hereinafter defined), (ii) participate in
any discussions or negotiations regarding, or furnish to any person any
non-public information with respect to, or take any other action to facilitate
any inquiries or the making of any proposal that constitutes a UHC Proposal,
(iii) engage in discussions with any person with respect to any UHC Proposal,
except as to the existence of these provisions, (iv) approve, endorse or
recommend any UHC Proposal or (v) enter into any letter of intent or similar
document or any contract, agreement or commitment contemplating or otherwise
relating to any UHC Proposal. UHC and its affiliates will immediately cease any
and all existing activities, discussions or negotiations with any parties
conducted heretofore with respect to any UHC Proposal. Without limiting the
foregoing, it is understood that any violation of the restrictions set forth in
the preceding two sentences by any officer, director or employee of UHC or any
of its affiliates or any investment banker, attorney or other advisor or
representative of UHC or any of its affiliates shall be deemed to be a breach of
this Section 5.4(c) by UHC. For purposes of this Agreement, "UHC PROPOSAL" shall
mean any offer or proposal relating to any transaction or series of related
transactions that would constitute a breach or violation of, the obligations
(including exclusivity obligations) of VHA, UHC, Novation and/or HPPI under the
Outsourcing Agreement. For purposes of this Section 5.4(c), UHC's "affiliates"
shall not include Novation or HPPI.

     (d) In addition to the obligations of UHC set forth in paragraph (c) of
this Section 5.4, UHC as promptly as practicable shall advise Parent orally and
in writing of any request for non-public information or inquiry which UHC
reasonably believes would lead to a UHC Proposal or of any UHC Proposal, the
material terms and conditions of such request, UHC Proposal or inquiry, and the
identity of the person or group making any such request, UHC Proposal or
inquiry. UHC will keep Parent informed as promptly as practicable in all
material respects of the status and details (including material amendments or
proposed amendments) of any such request, UHC Proposal or inquiry.

     5.5 Third Party Consents.  As soon as practicable following the date
hereof, Parent and UHC will each use its commercially reasonable efforts to
obtain any material consents, waivers and approvals under any of its or its
subsidiaries' respective agreements, contracts, licenses or leases required to
be obtained in connection with the consummation of the transactions contemplated
hereby.

     5.6 Nasdaq Listing.  Parent agrees to authorize for listing on the Nasdaq
Stock Market the Shares and Warrant Stock issuable in connection with this
Agreement, effective upon official notice of issuance.

     5.7 Takeover Statutes.  If any Takeover Statute is or may become applicable
to the transactions contemplated by this Agreement, each of Parent and UHC and
their respective Boards of Directors shall grant such approvals and take such
lawful actions as are necessary to ensure that such transactions may be
consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise act to eliminate or minimize the effects of such
Takeover Statute and any regulations promulgated thereunder on such
transactions.

                                   ARTICLE VI

                             ADDITIONAL AGREEMENTS

     6.1 Voting of Common Stock.  UHC agrees that from and after the date of the
Closing through the fifth anniversary of the Closing (the "FIFTH ANNIVERSARY"),
and for as long after the Fifth Anniversary as the outstanding shares of Common
Stock (including outstanding Common Stock that has been issued pursuant to the
Warrant) beneficially owned by UHC together with all "affiliates" (which for
purposes of this Agreement (other than Section 3.12) shall have the meaning
given such term in Rule 144(a)(1) promulgated under the
                                      C-22
<PAGE>   129

1933 Act) of UHC exceeds 9% of the then outstanding Common Stock of Parent (the
entire such period, the "RESTRICTED PERIOD"), to the extent that the outstanding
shares of Common Stock (including outstanding Common Stock that has been issued
pursuant to the Warrant) beneficially owned by UHC together with all affiliates
of UHC exceeds 9% of the then outstanding Common Stock of Parent (the shares in
excess of such 9% threshold, "EXCESS SHARES"), UHC shall, and shall cause its
controlled affiliates to, vote all Excess Shares it holds or is entitled to vote
in proportion to the votes cast by all other stockholders of Parent in
connection with each matter submitted to Parent's stockholders for approval
except for (i) a proposed Change of Control or (ii) an amendment of the
Certificate of Incorporation of Parent that would materially and adversely
affect UHC as a Parent stockholder in a manner different from the effect such
amendment would have on other Parent stockholders generally. On all matters
submitted to Parent stockholders for approval other than those identified in
items (i) and (ii) of the first sentence of this section, UHC shall, and shall
cause its controlled affiliates to, vote all Excess Shares in proportion to the
votes cast by all other stockholders of Parent in connection with each matter
submitted to Parent stockholders' for approval, including, without limitation,
on any matters regarding equity-based or other compensation plans of Parent, the
issuance of capital stock of Parent, amendments to the Certificate of
Incorporation of Parent other than as set forth in clause (ii) above, elections
of directors to the Board of Directors, or transactions involving interested or
related parties. Notwithstanding any voting restrictions set forth herein, the
Board of Directors of Parent may waive any voting restriction set forth herein
with respect to any particular matter. For purposes of this Agreement, "CHANGE
OF CONTROL" means the consummation of any transaction or series of related
transactions, including an acquisition of Parent by another entity and any
reorganization, merger, consolidation or share exchange, that results in the
beneficial owners of Parent's capital stock immediately prior to the transaction
or transactions holding less than 50% of the voting power of Parent immediately
after the transaction or transactions, or a transaction or series of related
transactions which result in the sale, exchange, transfer, acquisition or
disposition of more than 50% of the assets of Parent. For the avoidance of
doubt, for purposes of this Section 6.1, VHA, Novation and HPPI are not
"affiliates" of UHC.

     6.2 Acquisition of Parent Securities.  UHC agrees that during the
Restricted Period, (i) at any time that UHC together with all of its affiliates
beneficially owns 9% (on a Common Stock-equivalent basis) or more of the
outstanding shares of Common Stock or other capital stock of Parent or of any
option, warrant or right to acquire capital stock of Parent (such shares,
options, warrants and other rights, collectively, "RIGHTS IN PARENT STOCK"), UHC
will not, without the prior written consent of Parent, acquire legal or
beneficial ownership of any additional Rights in Parent Stock, except pursuant
to the Warrant, and (ii) at any time that UHC, together with all of its
affiliates beneficially owns less than 9% of the outstanding Rights in Parent
Stock, UHC may acquire such number of Rights in Parent Stock so that after the
acquisition of such Rights in Parent Stock the aggregate number of Rights in
Parent Stock, on a Common Stock-equivalent basis, legally or beneficially owned
by UHC and all affiliates of UHC, assuming issuance of all shares of Parent
Common Stock issuable pursuant to such Rights in Parent Stock, equals not more
than 9% of the outstanding Common Stock of Parent. For the avoidance of doubt,
for purposes of this Section 6.2, VHA, Novation and HPPI are not "affiliates" of
UHC.

     6.3 [Intentionally omitted]

     6.4 Parent Board of Directors; UHC Rights.

     (a) The Board of Directors of Parent will take all actions reasonably
necessary such that as soon as practicable following the Closing, the size of
Parent's Board of Directors shall be seven members, and two persons shall be
appointed by VHA to Parent's Board of Directors to fill vacancies in Class I.
Under the Parent's Charter Documents, the terms of Class I Directors expire in
2000, the terms of Class II Directors expire in 2001 and the terms of Class III
Directors expire in 2002. The Class I Directors appointed pursuant to this
Section shall be appointed following Parent's annual meeting in 2000. For so
long as VHA beneficially owns 10% or more of the outstanding Common Stock of
Parent on a fully converted basis (taking into account for VHA, all shares of
Common Stock issuable upon the exercise of the warrant issued to VHA pursuant to
the VHA Agreement), Parent will take all actions reasonably necessary to have
one person appointed by VHA be a member of Parent's Board of Directors. For so
long as VHA beneficially owns 20% or more of the Common Stock of Parent on a
fully converted basis (taking into account for VHA, all shares of Common
                                      C-23
<PAGE>   130

Stock issuable upon the exercise of the warrant issued to VHA pursuant to the
VHA Agreement), Parent will take all actions reasonably necessary to have two
persons appointed by VHA be members of Parent's Board of Directors. If Parent's
Board of Directors establishes an executive committee or another committee of
less than all directors having general authority similar to that customarily
delegated to an executive committee, one member of such committee shall be a
director nominated by VHA.

     (b) For the longer of (x) six years following the date of this Agreement or
(y) so long as UHC beneficially owns 9% or more of the Common Stock of Parent on
a fully converted basis (taking into account for UHC, all shares of Common Stock
issuable upon the exercise of the Warrant), if, in connection with the entry by
Parent into a commercial relationship with a group purchasing organization (a
"GPO") other than VHA, UHC, Novation or HPPI, Parent (i) issues equity
securities of Parent in aggregate amount equal to or less than the amount of
Parent equity securities issued to UHC hereunder or Parent enters into a
commercial relationship with a GPO which has a total cumulative dollar volume of
purchased contract products for the most recent complete calendar year preceding
the entry by such GPO into such commercial relationship equal to or less than
the total cumulative dollar volume of purchased contract products of UHC for the
same time period and (ii) Parent provides such GPO with the right to nominate a
person to Parent's Board of Directors, then Parent shall promptly offer UHC the
right to nominate a person to Parent's Board of Directors.

     (c) For the longer of (x) six years following the date of this Agreement or
(y) so long as UHC beneficially owns 9% or more of the Common Stock of Parent on
a fully converted basis (taking into account for UHC, all shares of Common Stock
issuable upon the exercise of the Warrant), Parent will provide a person
designated by UHC with all written materials and reports provided to Parent's
Board of Directors at the same time such materials and reports are provided to
Parent's Board of Directors; provided, that Parent shall not be obligated to
comply with the terms of this sentence if it is advised by outside counsel that
compliance with such obligations would jeopardize a legal privilege of Parent,
Parent's Board of Directors or any director, it being agreed that Parent will
notify UHC in writing of its non-compliance and the reasons therefor. For six
years following the date of this Agreement, at the request of UHC, on a once per
quarterly basis, the Chief Executive Officer and other members of Parent's
senior management shall meet with persons designated by UHC to review Parent's
operating results and business plan. For six years following the date of this
Agreement, UHC will have the exclusive right to nominate the chairperson of the
Parent User Advisory Board, subject to Parent's approval, such approval not to
be unreasonably withheld, and to assist Parent in the development and
maintenance of the composition of the Parent User Advisory Board.

     6.5 Reasonable Efforts.

     (a) Upon the terms and subject to the conditions set forth in this
Agreement, each of the parties agrees to use all reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other party in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the transactions contemplated by this Agreement, including using
reasonable efforts to accomplish the following: (i) the taking of all reasonable
acts necessary to cause the conditions precedent set forth in Articles VII and
VIII to be satisfied, (ii) the obtaining of all necessary actions or nonactions,
waivers, consents, approvals, orders and authorizations from Governmental
Entities and the making of all necessary registrations, declarations and filings
(including registrations, declarations and filings with Governmental Entities,
if any) and the taking of all reasonable steps as may be necessary to avoid any
suit, claim, action, investigation or proceeding by any Governmental Entity,
(iii) the obtaining of all necessary consents, approvals or waivers from third
parties, (iv) the defending of any suits, claims, actions, investigations or
proceedings, whether judicial or administrative, challenging this Agreement or
the consummation of the transactions contemplated hereby, including seeking to
have any stay or temporary restraining order entered by any court or other
Governmental Entity vacated or reversed and (v) the execution or delivery of any
additional instruments necessary to consummate the transactions contemplated by,
and to fully carry out the purposes of, this Agreement. Notwithstanding anything
in this Agreement to the contrary, neither Parent nor any of its affiliates
shall be under any obligation to make proposals, execute or carry out agreements
or submit to orders providing for the sale or other disposition or holding
separate (through the establishment of a trust or otherwise) of any assets or
categories of assets of

                                      C-24
<PAGE>   131

Parent or any of its affiliates or imposing or seeking to impose any limitation
on the ability of Parent or any of its subsidiaries or affiliates to conduct
their business or own such assets.

     (b) Each of UHC and Parent will give prompt notice to the other of (i) any
notice or other communication from any person alleging that the consent of such
person is or may be required in connection with the consummation of transactions
contemplated by this Agreement, (ii) any notice or other communication from any
Governmental Entity in connection with the transactions contemplated by this
Agreement or the Outsourcing Agreement, (iii) any litigation relating to,
involving or otherwise affecting UHC, Novation, HPPI, Parent or their respective
subsidiaries that relates to the consummation of the transactions contemplated
by this Agreement or the Outsourcing Agreement. UHC shall give prompt notice to
Parent of any representation or warranty made by it contained in this Agreement
becoming untrue or inaccurate, or any failure of UHC to comply with or satisfy
in any material respect any covenant, condition or agreement to be complied with
or satisfied by it under this Agreement, in each case, such that the conditions
set forth in Article VIII would not be satisfied, provided, however, that no
such notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement. Parent shall give prompt notice to UHC of any
representation or warranty made by it contained in this Agreement becoming
untrue or inaccurate, or any failure of Parent to comply with or satisfy in any
material respect any covenant, condition or agreement to be complied with or
satisfied by it under this Agreement, in each case, such that the conditions set
forth in Article VII would not be satisfied, provided, however, that no such
notification shall affect the representations, warranties, covenants or
agreements of the parties or the conditions to the obligations of the parties
under this Agreement.

     6.6 Registration Rights.  Parent shall use its reasonable best efforts to
cause the requisite holders of registration rights under the Second Amended and
Restated Registration Rights Agreement among Parent and certain of its investors
dated October 14, 1999 (the "EXISTING REGISTRATION RIGHTS AGREEMENT") to amend
and substitute for such agreement the Amended and Restated Registration Rights
Agreement in substantially the form attached hereto as Exhibit B (the "NEW
REGISTRATION RIGHTS AGREEMENT") effective as of the Closing. If as of the
Closing, the requisite holders of registration rights under the Existing
Registration Rights Agreement shall not have agreed to amend and substitute for
such agreement the New Registration Rights Agreement, then Parent and UHC shall
enter into, and Parent shall use its reasonable best efforts to cause the
holders of registration rights under the Existing Registration Rights Agreement
to enter into, effective as of the Closing, a registration rights agreement (the
"ALTERNATIVE REGISTRATION RIGHTS AGREEMENT") modeled upon the New Registration
Rights Agreement and only differing from the New Registration Rights Agreement
to the extent necessary so that the Alternative Registration Rights Agreement
does not conflict with or violate the Existing Registration Rights Agreement.

     6.7 Public Disclosure.  Parent and UHC will consult with each other, and to
the extent practicable, agree, before issuing any press release or otherwise
making any public statement with respect to this Agreement and will not issue
any such press release or make any such public statement prior to such
consultation, except as may be required by law or any listing agreement with a
national securities exchange. The parties have agreed to the text of the press
release announcing the signing of this Agreement.

                                  ARTICLE VII

                   CONDITIONS TO UHC'S OBLIGATIONS AT CLOSING

     Closing (other than representations and warranties that address matters
     only as of a particular date, which shall be true and correct as of such
     date), except where the failure of such representations or warranties to be
     true or correct would not have, individually or in the

                                      C-25
<PAGE>   132

     aggregate, a Material Adverse Effect on Parent. It is understood that, for
     purposes of determining the accuracy of such representations and
     warranties, any update of or modification to the Parent Disclosure Letter
     made or purported to have been made after the execution of this Agreement
     shall be disregarded. UHC shall have received a certificate with respect to

     the transactions contemplated hereby shall have been obtained (and all
     relevant statutory, regulatory or other governmental waiting periods, shall
     have expired) unless the failure to receive any such approval or consent
     would not be reasonably likely, directly or indirectly, to result in a
     Material Adverse Effect on Parent and its subsidiaries, taken as a whole,
     and (ii) all such approvals and consents which have been obtained shall be
     on terms that are not reasonably likely, directly or indirectly, to result
     in a Material Adverse Effect on Parent and its subsidiaries, taken as a

     Closing, whether before or after the requisite approval of the issuance of
     the Shares, the Warrant and the Warrant Stock by Parent's stockholders:

          (a) by mutual written consent duly authorized by the Boards of
     Directors of Parent and UHC;

          (b) by either Parent or UHC if the Closing shall not have occurred by
     September 30, 2000 for any reason; provided, however, that the right to
     terminate this Agreement under this Section 9.1(b) shall not be available
     to any party whose action or failure to act has been a principal cause of
     or resulted in the failure of the Closing to occur on or before such date
     and such action or failure to act constitutes a breach of this Agreement or
     the Outsourcing Agreement;

          (c) by either Parent or UHC if a Governmental Entity shall have issued
     an order, decree or ruling or taken any other action, in any case having
     the effect of permanently restraining, enjoining or otherwise prohibiting
     the Closing, which order, decree, ruling or other action is final and
     nonappealable;

          (d) by either Parent or UHC, if the approval of the issuance of the
     Shares, the Warrant and the Warrant Stock by the stockholders of Parent
     shall not have been obtained by reason of the failure to obtain the
     required vote at a meeting of Parent stockholders duly convened therefor or
     at any adjournment thereof;

          (e) by either Parent or UHC, if the Outsourcing Agreement is validly

     of this Agreement, or UHC, Novation or HPPI is in material breach of the
     Outsourcing Agreement, which breach has not been cured as of such time.

     For the purposes of this Agreement, a "TRIGGERING EVENT" shall be deemed to

of Directors of Parent fails to reaffirm its recommendation in favor of the
approval of the Parent Stockholder Approval within 10 business days after UHC
requests in writing that such recommendation be reaffirmed at any time following
the public announcement of a Parent Acquisition Proposal; (iv) the Board of
Directors of Parent or any committee thereof shall have approved or publicly
recommended any Parent Acquisition Proposal; (v) Parent shall have entered into
any letter of intent of similar document or any agreement, contract or
commitment accepting any Parent Acquisition Proposal; or (vi) Parent shall have
materially breached any of the provisions of Sections 5.2 or 5.4(a) or (b).

     9.2 Notice of Termination; Effect of Termination.  Any proper termination
of this Agreement under Section 9.1 will be effective immediately upon the
delivery of written notice of the terminating party to the other party hereto.
In the event of the termination of this Agreement as provided in Section 9.1,
this Agreement shall be of no further force or effect, except (i) as set forth
in this Section 9.2, Section 9.3 and Article X, each of which shall survive the
termination of this Agreement, and (ii) nothing herein shall relieve either
party from liability for any willful breach of this Agreement.

     9.3 Parent Payment.  In the event that this Agreement is terminated by UHC
pursuant to Section 9.1(f), Parent shall promptly, but in no event later than
two days after the date of such termination, pay UHC a fee equal to $3 million
in immediately available funds. In the event that (A) following the date of this
Agreement and prior to the Parent Stockholders' Meeting, a person has publicly
announced a bona fide Parent Acquisition Proposal, (B) this Agreement is
terminated by Parent or UHC pursuant to Section 9.1(d), and (C) within nine
months following the termination of this Agreement pursuant to Section 9.1(d),
either the Parent Acquisition contemplated by such Parent Acquisition Proposal
is consummated, or Parent enters into an agreement providing for a Parent
Acquisition and such Parent Acquisition is later consummated with the person (or
another person controlling, controlled by or under common control with, such
person) with whom such agreement was entered into (regardless of when such
consummation occurs if Parent has entered into such an agreement within such
nine-month period), Parent shall promptly, but in no event later than two days
after the consummation of such Parent Acquisition, pay UHC a fee equal to $3
million in immediately available funds. Parent acknowledges that the agreements
contained in this Section 9.3 are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, UHC would
not enter into this Agreement. Accordingly, if Parent fails to pay in a timely
manner the amounts due pursuant to this Section 9.3, and, in order to obtain
such payment, UHC makes a claim that results in a judgment against Parent for
the amounts set forth in this Section 9.3, Parent shall pay to UHC its
reasonable costs and expenses (including reasonable attorneys' fees and
expenses) in connection with such suit, together with interest on the amounts
set forth in this Section 9.3 at the prime rate of The Chase Manhattan Bank in
effect on the date such payment was required to be made.

                                FORM OF WARRANT

     NEITHER THIS WARRANT NOR THE SECURITIES ISSUABLE ON EXERCISE HEREOF HAVE
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR
UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO
RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD
EXCEPT AS PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS,
PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT
THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN
INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION
OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT
ANY PROPOSED TRANSFER OTHERWISE PERMITTED UNDER ANY CONTRACTUAL RESTRICTIONS ON
RESALE APPLICABLE TO THESE SECURITIES IS IN COMPLIANCE WITH THE ACT AND ANY
APPLICABLE STATE SECURITIES LAWS.

     THE SECURITIES REPRESENTED HEREBY MAY BE SUBJECT TO CERTAIN RESTRICTIONS ON
RESALE AND ON VOTING AND THE HOLDERS HEREOF MAY BE BOUND BY CERTAIN RESTRICTIONS
ON ACQUISITION OF THE ISSUER'S CAPITAL STOCK PURSUANT TO A COMMON STOCK AND

                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                               NEOFORMA.COM, INC.

No. U-1                                               Void after          , 2010

     THIS CERTIFIES THAT University HealthSystem Consortium, an Illinois
corporation ("UHC" or the "HOLDER"), or its permitted assigns is entitled to
purchase under this Warrant up to 7,519,436 shares (the "SHARES") of common
stock, par value $0.001 per share ("COMMON STOCK"), of Neoforma.com, Inc., a
Delaware corporation ("NEOFORMA" or the "COMPANY") at a per share price of $0.01
(the "EXERCISE PRICE") subject to the provisions and upon the terms and
conditions hereinafter set forth.

     This Warrant is issued this   day of        , 2000 (the "ISSUE DATE")
pursuant to that certain Amended and Restated Common Stock and Warrant Agreement
amended and restated as of May 24, 2000 (the "STOCK AND WARRANT AGREEMENT"), by
and between the Company and the Holder.

     1. Vesting and Term.

     1.1 Vesting.  Upon issuance, this Warrant shall not be exercisable or
vested with respect to any Shares. A total of 5,639,576 Shares shall be eligible
for vesting in accordance with Section 1.1.2 below ("TRANCHE A SHARES") and a
total of 1,879,860 Shares shall be eligible for vesting in accordance with
Section 1.1.3 below ("TRANCHE B SHARES"). Shares with respect to which this
Warrant becomes vested and exercisable are referred to as "VESTED SHARES."

     1.1.1. Definitions.

     "CUMULATIVE SIGNED PURCHASING VOLUME" means, as of any Determination Date,
the sum of (x) the cumulative dollar volume of purchases by Healthcare
Organizations that are members or patrons of UHC (calculated, for each such
Healthcare Organization, by multiplying (A) the amount of Novation LLC contract
purchases (as reported in the SRIS system maintained for Novation LLC's benefit)
by such Healthcare Organization during the most recent complete calendar year
ending prior to the first
                                      C-34
<PAGE>   141

Determination Date on or prior to which such Healthcare Organization Signed-Up
with Neoforma by (B) 2.4 (the "BASE AMOUNT")) and that Signed-Up with Neoforma
on or prior to such Determination Date, plus (y) 19.6% of the cumulative dollar
volume of purchases by Healthcare Organizations that are members or patrons of
Healthcare Purchasing Partners International, LLC (using, for each such
Healthcare Organization, its Base Amount) and that Signed-Up with Neoforma on or
prior to such Determination Date, provided that (i) for purposes of computing
the first Base Amount for each Healthcare Organization, such Base Amount will be
increased by 3.625% and (ii) in addition to the increase in the Base Amount for
any Healthcare Organization pursuant to the preceding clause (i), the Base
Amount for each Healthcare Organization shall also be increased annually by
7.25% when computing Cumulative Signed Purchasing Volume for Determination Dates
which are subsequent to the first Determination Date on or prior to which a
particular Healthcare Organization Signed-Up with Neoforma. For purposes of
clarity, the parties agree that once a Healthcare Organization is deemed to have
"Signed-Up" with Neoforma, its Cumulative Signed Purchasing Volume, as computed
and increased under the formula set forth in this definition, shall be included
in the computation of Cumulative Signed Purchasing Volume for all Determination
Dates arising on or after the date such Healthcare Organization Signed-Up with
Neoforma, whether or not such Healthcare Organization continues to do business
with Neoforma.

     "HEALTHCARE ORGANIZATION" shall mean any facility providing health care
services.

     "PREFERRED PROVIDER" means the Healthcare Organization agrees to use the
Neoforma internet-based system for at least 50% of its internet-based purchases
of Novation contracted products.

     "SIGNED-UP" means, with respect to any Healthcare Organization, that such
Healthcare Organization and Neoforma have entered into a written agreement,
arrangement or understanding for Neoforma to be the Preferred Provider of an
Internet-based system for the acquisition of Novation contracted products by
such Healthcare Organization.

     1.1.2. Vesting Requirements for Tranche A Shares.

     1. 1,409,894 Tranche A Shares shall become Vested Shares on June 30, 2001
(the "FIRST DETERMINATION DATE") if Cumulative Signed Purchasing Volume as of
the First Determination Date is at least $567 million (the "FIRST TRANCHE A
TARGET AMOUNT").

     2. 1,409,894 Tranche A Shares shall become Vested Shares on June 30, 2002
(the "SECOND DETERMINATION DATE") if Cumulative Signed Purchasing Volume as of
the Second Determination Date is at least $1,520 million (the "SECOND TRANCHE A
TARGET AMOUNT").

     3. 1,409,894 Tranche A Shares shall become Vested Shares on June 30, 2003
(the "THIRD DETERMINATION DATE") if Cumulative Signed Purchasing Volume as of
the Third Determination Date is at least $2,347 million (the "THIRD TRANCHE A
TARGET AMOUNT").

     4. 1,409,894 Tranche A Shares shall become Vested Shares on June 30, 2004
(the "FOURTH DETERMINATION DATE") if Cumulative Signed Purchasing Volume as of
the Fourth Determination Date is at least $3,231 million (the "FOURTH TRANCHE A
TARGET AMOUNT").

     5. In the event the Tranche A Target Amount of Cumulative Signed Purchasing
Volume specified in any of Section 1.1.2 paragraphs 1, 2, 3 or 4 above is not
achieved as of the particular Determination Date specified in such paragraph
(such shortfall below a particular Tranche A Target Amount being referred to as
a "TRANCHE A SHORTFALL AMOUNT"), then the number of Tranche A Shares which shall
become Vested Shares at a particular Determination Date pursuant to Section
1.1.2 paragraphs 1, 2, 3 or 4 shall equal the product of 1,409,894 and a
fraction, the numerator of which is the Cumulative Signed Purchasing Volume as
of the Determination Date in question and the denominator of which is the
Tranche A Target Amount for the Determination Date in question. By way of
example, using the formula in the preceding sentence, if as of

                                      C-35
<PAGE>   142

June 30, 2001, Cumulative Signed Purchasing Volume is $500 million, 1,243,293
Tranche A Shares shall become Vested Shares:

<TABLE>
  <C>           <C>  <S>
   1,409,894 X  500  = 1,243,293 Vested Shares
                ---
                567
</TABLE>

     If there is a Tranche A Shortfall Amount relating to a particular
Determination Date, then the number of Tranche A Shares which will not vest due
to such shortfall shall equal 1,409,894 minus the number of Tranche A Shares
which became Vested Shares on such Determination Date (the "TRANCHE A SHORTFALL
SHARES"). Using the facts set forth in the preceding example, if as of June 30,
2001, Cumulative Signed Purchasing Volume is $500 million, and 1,243,293 Tranche
A Shares become Vested Shares, then 166,601 Tranche A Shares shall be deemed
Tranche A Shortfall Shares as of the First Determination Date:

           1,409,894 - 1,243,293 = 166,601 Tranche A Shortfall Shares

     A Determination Date as of which there is a Tranche A Shortfall Amount is
referred to as a "TRANCHE A SHORTFALL DETERMINATION DATE". A Determination Date
which occurs immediately after a Tranche A Shortfall Determination Date is
referred to as a "TRANCHE A CATCH UP DETERMINATION DATE". If as of a Tranche A
Catch Up Determination Date, the applicable Tranche A Target Amount for such
Tranche A Catch Up Determination Date is met or exceeded, then the Tranche A
Shortfall Shares which did not vest on such Tranche A Shortfall Determination
Date shall immediately become Vested Shares on the Tranche A Catch Up
Determination Date, it being agreed that if the Tranche A Target Amount relating
to such Tranche A Catch Up Determination Date is not met, such Tranche A
Shortfall Shares shall never become vested. By way of example, if the Tranche A
Shortfall Amount on the First Determination Date is $67 million resulting in
166,601 Tranche A Shortfall Shares, and as of the Second Determination Date
(which, in this example, is the Tranche A Catch Up Determination Date with
respect to the First Determination Date) the Second Tranche A Target Amount of
Cumulative Signed Purchasing Volume of $1,520 million is met, then the 166,601
Tranche A Shortfall Shares relating to the First Determination Date which had
become a Tranche A Shortfall Determination Date will become Vested Shares on the
Second Determination Date, provided however, that if as of the Second
Determination Date Cumulative Signed Purchasing Volume is less than $1,520
million, the 166,601 Tranche A Shortfall Shares relating to the First
Determination Date shall never become vested, even if as of the Third
Determination Date or the Fourth Determination Date the relevant Tranche A
Target Amount for such Determination Date is met or exceeded.

     6. If, on the December 15 immediately preceding a Determination Date, UHC
delivers to Neoforma written evidence establishing that a number of Tranche A
Shares would become Vested Shares on such December 15 if such December 15 were
to be treated as if it were the immediately following Determination Date (but
not any other subsequent Determination Date or December 15), then such Shares
shall become Vested Shares as of such December 15, and the number of Shares
eligible to become Vested Shares on the immediately following Determination Date
shall be reduced by a like amount. If less than all of the Tranche A Shares
available to become Vested Shares on a particular December 15 become Vested
Shares on such date, any and all such Shares which did not become Vested Shares
on such December 15 may become Vested Shares on the Determination Date
immediately following such December 15 in accordance with the pro rata
provisions of paragraph 5, and if such Determination Date immediately following
such December 15 is a Tranche A Shortfall Determination Date, each of the
December 15 immediately following such Tranche A Shortfall Determination Date
and the Determination Date immediately following such Tranche A Shortfall
Determination Date, but no other December 15 or Determination Date, shall be a
Tranche A Catch Up Determination Date for such Tranche A Shortfall Determination
Date. All other provisions and limitations of paragraph 5 with respect to a
Tranche A Catch Up Determination Date shall be applicable.

     1.1.3 Vesting Requirements for Tranche B Shares.

     1. 469,965 Tranche B Shares shall become Vested Shares on the First
Determination Date if Cumulative Signed Purchasing Volume as of the First
Determination Date is at least $757 million (the "FIRST TRANCHE B TARGET
AMOUNT").

     2. 469,965 Tranche B Shares shall become Vested Shares on the Second
Determination Date if Cumulative Signed Purchasing Volume as of the Second
Determination Date is at least $2,026 million (the "SECOND TRANCHE B TARGET
AMOUNT").

     3. 469,965 Tranche B Shares shall become Vested Shares on the Third
Determination Date if Cumulative Signed Purchasing Volume as of the Third
Determination Date is at least $3,130 million (the "THIRD TRANCHE B TARGET
AMOUNT").

     4. 469,965 Tranche B Shares shall become Vested Shares on the Fourth
Determination Date if Cumulative Signed Purchasing Volume as of the Fourth
Determination Date is at least $4,308 million (the "FOURTH TRANCHE B TARGET
AMOUNT").

     5. In the event the Tranche B Target Amount of Cumulative Signed Purchasing
Volume specified in any of Section 1.1.3 paragraphs 1, 2, 3, or 4 above is not
achieved as of the particular Determination Date specified in such paragraph
(such shortfall below a particular Tranche B Target Amount being referred to as
a "TRANCHE B SHORTFALL AMOUNT"), then the number of Tranche B Shares which shall
become Vested Shares at a particular Determination Date pursuant to Section
1.1.3 paragraphs 1, 2, 3 or 4 shall equal the product of 469,965 and a fraction,
the numerator of which is the Cumulative Signed Purchasing Volume as of the
Determination Date in question minus the Tranche A Target Amount for the
Determination Date in question and the denominator of which is the Tranche B
Target Amount for the Determination Date in question minus the Tranche A Target
Amount for the Determination Date in question. It is agreed that no Tranche B
Shares will become Vested Shares on a particular Determination Date if the
Tranche A Target Amount relating to such Determination Date is not exceeded. By
way of example, if as of June 30, 2001, Cumulative Signed Purchasing Volume is
$700 million, 328,976 Tranche B Shares shall become Vested Shares:

<TABLE>
  <C>        <C>        <S>
  469,965 X  700 - 567  = 328,976 Vested Shares
             ---------
             757 - 567
</TABLE>

     If there is a Tranche B Shortfall Amount relating to a particular
Determination Date, then the number of Tranche B Shares which will not vest due
to such shortfall shall equal 469,965 minus the number of Tranche B Shares which
became Vested Shares on such Determination Date (the "TRANCHE B SHORTFALL
SHARES"). If no Tranche B Shares became Vested Shares on a Determination Date,
then there will be 469,965 Tranche B Shortfall Shares with respect to the
Determination Date in question. Using the facts set forth in the preceding
example, if as of June 30, 2001, Cumulative Signed Purchasing Volume is $700
million, and 328,976 Tranche B Shares become Vested Shares, then 140,989 Tranche
B Shares shall be deemed Tranche B Shortfall Shares as of the First
Determination Date:

             469,965 - 328,976 = 140,989 Tranche B Shortfall Shares

     A Determination Date as of which there is a Tranche B Shortfall Amount is
referred to as a "TRANCHE B SHORTFALL DETERMINATION DATE". A Determination Date
which occurs immediately after a Tranche B Shortfall Determination Date is
referred to as a "TRANCHE B CATCH UP DETERMINATION DATE". If as of a Tranche B
Catch Up Determination Date, the applicable Tranche B Target Amount for such
Tranche B Catch Up Determination Date is met or exceeded, then the Tranche B
Shortfall Shares which did not vest on such Tranche B Shortfall Determination
Date shall immediately become Vested Shares on the Tranche B Catch Up
Determination Date, it being agreed that if the Tranche B Target Amount relating
to such Tranche B Catch Up Determination Date is not met, such Tranche B
Shortfall Shares shall never become vested. By way of example, if the Tranche B
Shortfall Amount on the First Determination Date is $57 million resulting in
140,989 Tranche B Shortfall Shares, and as of the Second Determination Date
(which, in this example, is the Tranche B Catch Up Determination Date with
respect to the First Determination Date) the Second Tranche B Target Amount of
Cumulative Signed Purchasing Volume of $2,026 million is met, then the 140,989
Tranche B Shortfall Shares relating to the First Determination Date which had
become a Shortfall Determination Date will become Vested Shares on the Second
Determination Date, provided however, that if as of the Second Determination
Date Cumulative Signed Purchasing Volume is less than $2,026 million, the
140,989 Tranche B Shortfall Shares relating to the First Determination Date
shall never become vested, even

                                      C-37
<PAGE>   144

if as of the Third Determination Date or the Fourth Determination Date the
relevant Tranche B Target Amount for such Determination Date is met or exceeded.

     6. If, on the December 15 immediately preceding a Determination Date, UHC
delivers to Neoforma written evidence establishing that a number of Tranche B
Shares would become Vested Shares on such December 15 if such December 15 were
to be treated as if it were the immediately following Determination Date (but
not any other subsequent Determination Date or December 15), then such Shares
shall become Vested Shares as of such December 15, and the number of Shares
eligible to become Vested Shares on the immediately following Determination Date
shall be reduced by a like amount. If less than all of the Tranche B Shares
available to become Vested Shares on a particular December 15 become Vested
Shares on such date, any and all such Shares which did not become Vested Shares
on such December 15 may become Vested Shares on the Determination Date
immediately following such December 15 in accordance with the pro rata
provisions of paragraph 5, and if such Determination Date immediately following
such December 15 is a Tranche B Shortfall Determination Date, each of the
December 15 immediately following such Tranche B Shortfall Determination Date
and the Determination Date immediately following such Tranche B Shortfall
Determination Date, but no other December 15 or Determination Date, shall be a
Tranche B Catch Up Determination Date for such Tranche B Shortfall Determination
Date. All other provisions and limitations of paragraph 5 with respect to a
Tranche B Catch Up Determination Date shall be applicable.

     1.2 Acceleration of Vesting.  In the event of a merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving the Company in which all shares of Common Stock of the
Company are converted into cash, or a cash tender offer for all shares of Common
Stock is consummated, this Warrant will become fully exercisable as to all of
the Shares effective upon consummation of such transaction, and this Warrant
will expire on the later of the date of such consummation or twenty days after
written notice of such transaction, provided that the Holder may exercise this
Warrant contingent on the consummation of such transaction.

     1.3 Termination Date.  Unless this Warrant expires pursuant to Section 1.2,
this Warrant shall remain exercisable with respect to Vested Shares, if any,
until 5:00 p.m. California time on the tenth anniversary of the Issue Date at
which time the Warrant shall expire and be of no further force and effect.

     2. Exercise or Conversion.

     2.1 Method of Exercise; Payment; Issuance of New Warrant.  This Warrant may
be exercised by the Holder, in whole or in part and from time to time as to
Vested Shares, by the surrender of this Warrant (with a notice of exercise in
the form attached as Exhibit A and the investment representation certificate in
the form attached as Exhibit B, each duly executed) at the principal office of
the Company and by the payment to the Company by check or wire transfer of an
amount equal to the then current Exercise Price per share multiplied by the
number of Vested Shares then being purchased (the "AGGREGATE EXERCISE PRICE").
The Holder shall be deemed to have become the holder of record of, and shall be
treated for all purposes as the record holder of the Vested Shares represented
thereby, and such Vested Shares shall be deemed to have been issued, immediately
prior to the close of business on the date or dates upon which this Warrant is
exercised. In the event of any exercise of this Warrant, certificates for the
Vested Shares so purchased shall be delivered to the Holder as soon as possible
and in any event within ten business days of receipt of such notice by the
Company and, unless this Warrant has been fully exercised or expired, a new
Warrant representing the portion of the Shares, if any, with respect to which
this Warrant shall not then have been exercised shall also be issued to the
Holder as soon as possible and in any event within such ten business day period.

     2.2 Right to Convert Warrant into Stock; Net Issuance.  In addition to and
without limiting the rights of the Holder under the terms of this Warrant, the
Holder may elect to exercise this Warrant with respect to then Vested Shares
(the "CONVERSION RIGHT"), the aggregate value of which Vested Shares shall be
equal to the "in-the-money" value of this Warrant or the portion thereof being
converted as set forth below. The Conversion Right may be exercised by the
Holder by surrender of this Warrant at the principal office of the

                                      C-38
<PAGE>   145

Company together with notice of the Holder's intention to exercise the
Conversion Right, in which event the Company shall issue to the Holder a number
of Vested Shares computed using the following formula:

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

Where:

     X  The number of Vested Shares to be issued to the Holder.

     Y  The number of Vested Shares representing the portion of this Warrant
        that is being converted.

     A  The fair market value of one Share.

     B  The Exercise Price (as adjusted to the date of such calculations).

For purposes of this Section 2.2, the "fair market value" per Share shall mean
the market price of one share of Common Stock on the last business day before
the effective date of exercise of the Conversion Right. If the Common Stock is
then traded on a national securities exchange or admitted to unlisted trading
privileges on such an exchange, or is listed on the Nasdaq Stock Market (the
"NASDAQ MARKET"), the market price as of a specified day shall be the last
reported sale price of one share of Common Stock on such exchange or on the
Nasdaq Market on such date or if no such sale is made on such day, the mean of
the closing bid and asked prices for such day on such exchange or on the Nasdaq
Market. If the Common Stock is not so listed or admitted to unlisted trading
privileges, the market price as of a specified day shall be the mean of the last
bid and asked prices for one share of Common Stock reported on such date (x) by
the NASD or (y) if reports are unavailable under clause (x) above by the
National Quotation Bureau Incorporated. If the Common Stock is not so listed or
admitted to unlisted trading privileges and bid and asked prices are not
reported, the market price of one share of Common Stock as of a specified day
shall be determined in good faith by written resolution of the Board of
Directors of the Company.

     2.3 Automatic Conversion.  In the event of termination of this Warrant
pursuant to Section 1 above, to the extent that this Warrant is then exercisable
and such exercise would result in the issuance of Shares to the Holder, this
Warrant shall be deemed automatically exercised in full under Section 2.2 above
immediately prior to the time at which it would otherwise expire.

     2.4 HSR Compliance.  Exercise or conversion of this Warrant is subject to
compliance by the Holder with all applicable filing requirements, and expiration
of all applicable waiting periods, under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR ACT"). The Company will cooperate
with the Holder in making all applicable filings under the HSR Act, provided,
however, that the Holder shall pay all applicable filing fees.

     3. Securities Fully Paid; Reservation of Shares.  All Shares that may be
issued upon the exercise of the rights represented by this Warrant, upon
issuance, will be fully paid and nonassessable, and free from all taxes, liens
and charges with respect to the issue thereof. During the period within which
the rights represented by the Warrant may be exercised, the Company will at all
times have authorized and reserved for the purpose of issuance upon exercise of
the purchase rights evidenced by this Warrant, a sufficient number of shares of
Common Stock to provide for the exercise of the rights represented by this
Warrant. The Shares to be issued upon exercise or conversion of this Warrant
shall be approved for listing on the Nasdaq Market, subject to official notice
of issuance.

     4. Adjustment of Exercise Price and Number of Shares.  The Exercise Price
and the number and kind of securities or other property purchasable upon the
exercise of the Warrant shall be subject to adjustment from time to time upon
the occurrence of certain events, as follows:

     4.1 Reclassification or Merger.  In case of any reclassification, change or
conversion of securities in the class issuable upon exercise of this Warrant
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination), or in
case of any merger of the Company with or into another corporation (other than a
merger with another corporation in

                                      C-39
<PAGE>   146

which the Company is a continuing corporation and which does not result in any
reclassification or change of outstanding securities issuable upon exercise of
this Warrant), unless this Warrant shall have been exercised or terminated in
accordance with its terms, this Warrant shall thereafter be exercisable solely
for the kind and amount of consideration, including but not limited to shares of
stock, other securities, money and property, that the Holder would have received
upon such reclassification, change, conversion or merger if the Holder had
exercised this Warrant in full prior to such reclassification, change,
conversion or merger. The provisions of this subparagraph shall similarly apply
to successive reclassifications, changes, conversions or mergers. The Company
agrees to make appropriate provision in any definitive agreements providing for
such a transaction in order to carry out the terms of this Section.

     4.2 Subdivisions or Combination of Shares.  If at any time while this
Warrant remains outstanding and unexpired the Company shall subdivide or combine
the securities of the class issuable upon exercise of this Warrant, the Exercise
Price and the number of Shares issuable upon exercise hereof shall be
proportionately adjusted.

     4.3 Stock Dividends.  If, at any time while this Warrant is outstanding and
unexpired, the Company shall pay a dividend payable in securities of the class
issuable upon exercise of this Warrant (except any distribution specifically
provided for in the foregoing subparagraphs 4.1 and 4.2), then the Exercise
Price shall be adjusted, from and after the date of determination of
stockholders entitled to receive such dividend or distribution, to that price
determined by multiplying the Exercise Price in effect immediately prior to such
date of determination by a fraction, the numerator of which shall be the total
number of shares of such class of securities outstanding immediately prior to
such dividend or distribution, and the denominator of which shall be the total
number of shares of such class of securities outstanding immediately after such
dividend or distribution, and the number of Shares subject to this Warrant shall
be proportionately adjusted.

     4.4 Common Stock Rights.  If, at any time while this Warrant is outstanding
and unexpired, the Company shall pay a dividend or other distribution on all
Common Stock consisting of, or shall otherwise issue to all holders of Common
Stock, rights, warrants or options (not being available on an equivalent basis
to the Holders of this Warrant upon exercise) entitling the holders of Common
Stock to subscribe for or purchase Common Stock at a price per share less than
the current market price (determined as provided in Section 2.2) of a share of
Common Stock on the date fixed for the determination of stockholders entitled to
receive such rights, warrants or options (other than pursuant to a dividend
reinvestment plan), the Exercise Price shall be decreased by multiplying the
then current Exercise Price by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock
which the aggregate of the offering price of the total number of shares of
Common Stock so offered for subscription or purchase would purchase at such
current market price, and the denominator of which shall be the number of shares
of Common Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such decrease to become effective immediately after
the opening of business on the day following the date fixed for such
determination. In the event that such rights or warrants are not so issued, the
Exercise Price shall again be adjusted to be the Exercise Price which would then
be in effect if such date fixed for the determination of stockholders entitled
to receive such rights, warrants or options had not been fixed. Upon adjustment
of the Exercise Price pursuant to this Section 4.4, the number of shares subject
to issuance upon exercise of this Warrant shall be adjusted by multiplying such
number of shares prior to such adjustment by a fraction, the numerator of which
is the Exercise Price in effect immediately prior to such adjustment and the
denominator of which is the Exercise Price in effect immediately after giving
effect to such adjustment. In making any determinations under this Section 4.4,
there shall be taken into account any consideration received for such rights,
warrants or options, the value of which consideration, if other than cash, shall
be fixed in good faith by the Board of Directors of the Company, whose
determination shall be final.

     4.5 Distributions of Property.  If, at any time while this Warrant is
outstanding and unexpired, the Company shall pay a dividend or other
distribution on all Common Stock consisting of evidences of its indebtedness or
assets (excluding any dividend or distribution paid in cash, or any dividend or
distribution described in Sections 4.2, 4.3 or 4.4 of this Warrant), the
Exercise Price shall be decreased by multiplying the
                                      C-40
<PAGE>   147

then current Exercise Price by a fraction, the numerator of which shall be the
current market price (determined as provided in Section 2.2) of a share of
Common Stock on the date fixed for the determination of stockholders entitled to
receive such dividend or distribution less the fair market value (as determined
by the Board of Directors of Company, whose determination shall be final) of the
portion of indebtedness or assets so distributed applicable to one share of
Common Stock and the denominator of which shall be such current market price of
a share of Common Stock, such decrease to become effective immediately after the
opening of business on the day following the date fixed for such determination.
In the event that such dividend or distribution is not so made, the Exercise
Price shall again be adjusted to be the Exercise Price which would then be in
effect if such date fixed for the determination of stockholders entitled to
receive such dividend or distribution had not been fixed. Upon adjustment of the
Exercise Price pursuant to this Section 4.5, the number of shares subject to
issuance upon exercise of this Warrant shall be adjusted by multiplying such
number of shares prior to such adjustment by a fraction, the numerator of which
is the Exercise Price in effect immediately prior to such adjustment and the
denominator of which is the Exercise Price in effect immediately after giving
effect to such adjustment.

     4.6 Notice of Adjustments.  Whenever the Exercise Price shall be adjusted
pursuant to the provisions hereof, the Company shall within thirty days of such
adjustment deliver a certificate to the Holder signed by its chief financial
officer setting forth, in reasonable detail, the event requiring the adjustment,
the amount of the adjustment, the method by which such adjustment was
calculated, and the number of Shares subject to this Warrant and the Exercise
Price therefor, as applicable, after giving effect to such adjustment.

     5. Compliance with Securities Laws; Restrictions on Transfer.

     5.1 Accredited Investor.  This issuance of this Warrant is conditioned
upon, and by its acceptance hereof the Holder hereby confirms, that the Holder
is an "accredited investor" as that term is defined under Regulation D under the
Securities Act of 1933, as amended.

     5.2 Legend.  Upon issuance, certificates evidencing the Shares shall bear
legends in substantially the form set forth in the Purchase Agreement.

     5.3 Transfer Restrictions; Compliance with Securities Laws on
Transfer.  This Warrant may not be transferred in whole or in part without the
prior written consent of the Company, except that such consent shall not be
required for the transfer of all or any part of this Warrant covering Vested
Shares. Any purported transfer of this Warrant in violation of the foregoing
restriction shall be void, and the Company shall not recognize any such
purported transfer on the securities ledger of the Company. In addition, no
permitted transfer of this Warrant or the Shares may be made without compliance
with applicable federal and state securities laws by the transferor and the
transferee (including, without limitation, the delivery of investment
representation letters and legal opinions reasonably satisfactory to the
Company). The Company will reasonably cooperate with the Holder in connection
with any permitted transfer of this Warrant, including by issuing new
certificates representing the Warrant and any portion thereof so transferred.

     6. Fractional Shares.  No fractional Shares will be issued in connection
with any exercise hereunder, but in lieu of such fractional Shares the Company
shall make a cash payment therefor upon the basis of the Exercise Price then in
effect.

     7. Modification and Waiver.  This Warrant and any provision hereof may be
changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

     8. Notices.

     8.1 Notice of Certain Events.  The Company shall provide the Holder with at
least twenty days notice (or such greater amount of notice as Delaware law
requires to be given to stockholders having the right to vote at a meeting on
any Sale Event, as defined herein) prior to (i) a merger of the Company with or
into, the consolidation of the Company with, or the sale by the Company of all
or substantially all of its assets to, another person or entity (other than such
a transaction wherein the stockholders of the Company prior to such transaction
retain or obtain a majority of the voting capital stock of the surviving,
resulting or purchasing

                                      C-41

entity) (a "SALE EVENT"), (ii) any liquidation, dissolution or winding up of the
Company or (iii) the record date for any cash or other dividend or distribution
declared on the Shares (each, a "NOTICE EVENT"). If a notice is provided
pursuant to subsection (i) or (ii) of the previous sentence, the notice will
indicate the expected date of the Notice Event.

     8.2 Notice Procedure.  All notices and other communications hereunder shall
be in writing and shall be deemed given upon delivery either personally or by
commercial delivery service, or sent via facsimile (receipt confirmed) to the

upon and shall inure to the benefit of the parties hereto and their respective
successors and permitted assigns. Any purported assignment in violation of this
Section shall be void.

     In connection with the purchase of the above-listed securities (the
"SHARES"), the undersigned (the "HOLDER") represents to the Company as follows:

     The Shares to be purchased by or delivered to the Holder hereunder will be
acquired for investment for such Holder's own account, not as a nominee or
agent, and not with a view to the public resale or distribution thereof within
the meaning of the Securities Act of 1933, as amended ("1933 ACT"), and Holder
represents that it has no present intention or agreement to sell, grant any
participation in, or otherwise distribute any of the Shares to be acquired
hereunder in any public resale or distribution within the meaning of the 1933
Act. Holder also represents that it has not been formed for the specific purpose
of acquiring Securities under this Agreement.

     Holder has received or has had full access to all the information it
considers necessary or appropriate to make an informed investment decision with
respect to the Shares to be purchased under this Agreement. Holder further has
had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of the offering of the Shares and to obtain
additional information (to the extent the Company possessed such information or
could acquire it without unreasonable effort or expense) necessary to verify any
information furnished to Holder or to which Holder had access.

     Holder understands that the purchase of the Shares involves substantial
risk. Holder: (i) has experience as an investor in securities of companies in
the development stage and acknowledges that Holder is able to fend for itself,
can bear the economic risk of Holder's investment in the Shares and has such
knowledge and experience in financial or business matters that Holder is capable
of evaluating the merits and risks of this investment in the Shares and
protecting its own interests in connection with this investment and/or (ii) has
a preexisting personal or business relationship with the Company and certain of
its officers, directors or controlling persons of a nature and duration that
enables Holder to be aware of the character, business acumen and financial
circumstances of such persons. Holder is an "accredited investor" within the
meaning of Regulation D promulgated under the 1933 Act.

     Holder understands that the Shares are characterized as "restricted
securities" under the 1933 Act inasmuch as they are being acquired from the
Company in a transaction not involving a public offering and that under the 1933
Act and applicable regulations thereunder such securities may be resold without
registration under the 1933 Act only in certain limited circumstances. In this
connection, such Holder represents that Holder is familiar with Rule 144 of the
Securities and Exchange Commission, as presently in effect, and understands the
resale limitations imposed thereby and by the 1933 Act.

     At no time was Holder presented with or solicited by any publicly issued or
circulated newspaper, mail, radio, television or other form of general
advertising or solicitation in connection with the offer, sale and purchase of
the Shares.

     Without in any way limiting the representations set forth above, Holder
further acknowledges that the Shares are subject to limitations on disposition
thereof set forth in the Warrant and in that certain Amended and Restated Common
Stock and Warrant Agreement, dated as of May 24, 2000 by and between the Company
and Holder, and acknowledges that Holder is bound by such restrictions.

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
     AS AMENDED (THE "ACT"). SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE

     REGISTRATION RIGHTS AGREEMENT, A COPY OF WHICH MAY BE OBTAINED FROM THE

to the estate of any of its partners or retired partners, (iii) a transfer to an
Affiliate, an affiliated fund, partnership or Company, which is not a competitor
of the Company, subject to compliance with applicable securities laws, or (iv)

satisfactory evidence of compliance with such Rule), unless there is in effect a
registration statement under the Securities Act covering the proposed transfer,
the holder thereof shall give written notice to the Company of such holder's
intention to effect such transfer, sale, assignment or pledge. Each such notice
shall describe the manner and circumstances of the proposed transfer, sale,
assignment or pledge in sufficient detail, and shall be accompanied by either of
the following, at such holder's expense: (i) a written opinion of legal counsel
who shall, and whose legal opinion shall, be reasonably satisfactory to the
Company addressed to the Company, to the effect that the proposed transfer of
the Restricted Securities may be effected without registration under the
Securities Act, or (ii) a "no action" letter from the Commission to the effect
that the transfer of such securities without registration will not result in a
recommendation by the staff of the Commission that action be taken with respect
thereto, whereupon the holder of such Restricted Securities shall be entitled to
transfer such Restricted Securities in accordance with the terms of the notice
delivered by the holder to the Company. Each certificate evidencing the
Restricted Securities transferred as above provided shall bear, except if such
transfer is made pursuant to Rule 144, the appropriate restrictive legend set
forth in Section 2.2 above, except that such certificate shall not bear such
restrictive legend if in the opinion of counsel for such holder and in the

     2.4 Removal of Restrictions on Transfer of Restricted Securities. Any
legend referred to in Section 2.2 hereof stamped on a certificate evidencing (i)
the Restricted Securities or (ii) any other securities issued in respect of the

merger, consolidation or similar event and the stock transfer instructions and
record notations with respect to such security shall be removed and the Company
shall issue a certificate without such legend to the holder of such
                                      C-50
<PAGE>   157

security if such security is registered under the Securities Act, or if such
holder provides the Company with an opinion of counsel (which may be counsel for
the Company) reasonably acceptable to the Company to the effect that a public
sale or transfer of such security may be made without registration under the
Securities Act or (iii) such holder provides the Company with reasonable
assurances, which may, at the option of the Company, include an opinion of
counsel satisfactory to the Company, that such security can be sold pursuant to

     3. [Intentionally Omitted].

     4. Registration Rights.

     4.1 Requested Registration.

     (a) Requested Registration. If the Company shall receive from the
Initiating Holders a written request that the Company file a registration
statement for (i) at least 75% of the Registrable Securities, (ii) at least 60%
of the Series E Registrable Securities, or (iii) Novation Registrable Securities
having a current market value of at least $30 million, and in the case of clause
(i) or (ii) the aggregate gross proceeds of which registration would equal or
exceed $20,000,000 (any such notice, an "INITIATION NOTICE"), then the Company
will:

          (A) within ten days of the receipt by the Company of the Initiation
     Notice, give written notice of the proposed registration, qualification or
     compliance to all other Holders (the notice in this Section 4.1(a)(i) and
     in Section 4.2(a)(i), each called the "REGISTRATION NOTICE"); and

          (B) use its best efforts to effect, as soon as practicable and in any
     event within ninety (90) days after receipt of the Initiation Notice, such
     registration, qualification or compliance (including, without limitation,
     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) as may be so requested and as would permit or facilitate the
     sale and distribution of all or such portion of such Registrable Securities
     as are specified in such request, together with all or such portion of the
     Registrable Securities of any Holder or Holders joining in such request as
     are specified in a written request received by the Company within 20 days
     after receipt of the Registration Notice from the Company;

     Provided, however, that the Company shall not be obligated to take any
action to effect any such registration, qualification or compliance pursuant to
this Section 4.1:

          (1) Prior to January 24, 2001.

          (2) In any particular jurisdiction in which the Company would be
     required to qualify to do business or to execute a general consent to
     service of process in effecting such registration, qualification or
     compliance;

          (3) During the period starting with the date sixty (60) days prior to
     the Company's estimated date of filing of any registration statement for
     the securities of the Company, and ending (except as provided below) on the
     date six (6) months immediately following the effective date of any
     registration statement pertaining to securities of the Company, provided
     that the Company is actively employing in good faith all reasonable efforts
     to cause such registration statement to become effective, and, provided,
     further, that the standstill period in this clause (3) shall not apply to a
     registration regarding a transaction described in subsection (a) of Rule
     145 as promulgated under the Securities Act ("RULE 145") or with respect to
     securities issued or issuable under an employee benefit plan or other
     similar plan or agreement;

          (4) After the Company has effected two (2) such registrations
     requested by holders of at least 60% of the Series E Initiating Holders,
     three (3) such registrations requested by holders of the Novation
     Registrable Securities, and two (2) additional registrations pursuant to
     this Section 4.1(a), and such registrations have been declared or ordered
     effective. The Company shall not be obligated to effect more than one such
     registration requested by the holders of the Novation Registrable
     Securities in any twelve month period.

                                      C-51
<PAGE>   158

          (5) If the Company shall furnish to such Holders a certificate signed
     by the President of the Company stating that in the good faith judgment of
     the Board of Directors it would be seriously detrimental to the Company or
     its stockholders for a registration statement to be filed in the near
     future, then the Company's obligation to use its best efforts to register,
     qualify or comply under this Section 4.1 shall be deferred for a period not
     to exceed ninety (90) days from the date of receipt of written request from
     the Initiating Holders; provided, however, that the Company shall not
     exercise such right more than once in any twelve (12) month period.

     (b) Underwriting. The Company shall have the right to select one or more
underwriters to manage a registration under Section 4.1, subject to the approval
of the holders of a majority of the Registrable Securities requesting
registration, which will not be unreasonably withheld, conditioned or delayed.
If the registration described in the Registration Notice is a registered public
offering involving an underwriting, the Company shall so advise the Holders as a
part of the Registration Notice. In such event, the right of any Holder to
registration pursuant to Section 4.1 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company. The Company
will not include in any registration under Section 4.1 any securities other than
Registrable Securities and securities to be registered for offering and sale on
behalf of the Company without the prior written consent of the holders of a
majority of the Registrable Securities requesting registration. If the managing
underwriter(s) advise the Company in writing that in their opinion the number of
Registrable Securities and, if permitted hereunder, other securities in such
offering, exceeds the number of Registrable Securities and other securities, if
any, that can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities initially
requesting registration, the Company will include in such registration, prior to
the inclusion of any securities that are not Registrable Securities, the number
of Registrable Securities requested to be included that in the opinion of such
underwriters can be sold in an orderly manner within the price range of such
offering, pro rata among the respective holders thereof on the basis of the
number of Registrable Securities that each such holder has requested the Company
to include in such registration.

     If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such Holder may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the Initiating Holders. The
Registrable Securities and/or other securities so withdrawn shall also be
withdrawn from registration, and such Registrable Securities shall not be
transferred in a public distribution prior to one hundred eighty (180) days
after the effective date of such registration, or such other shorter period of
time as the underwriters may require.

     4.2 Company Registration.

     (a) Notice of Registration. If at any time or from time to time the Company
shall determine to register any of its securities, either for its own account or
the account of a security holder or holders, other than (i) a registration with
respect to securities issued or to be issued in an employee benefit plan or
other similar plan or agreement, (ii) a registration relating solely to a
transaction described in Rule 145, (iii) a registration on any form which does
not permit registration of securities of the Company for secondary sales or (iv)
a registration pursuant to Section 4.1 hereof, the Company will:

          (i) promptly give to each Holder the Registration Notice; 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 Securities specified in a written request or
     requests, made within ten (10) days after receipt of the Registration
     Notice from the Company, by any Holder.

     (b) Underwriting. If the registration described in the Registration Notice
is a registered public offering involving an underwriting, the Company shall so
advise the Holders as a part of the Registration Notice. In such event, the
right of any Holder to registration pursuant to Section 4.2 shall be conditioned
upon such

                                      C-52
<PAGE>   159

Holder's participation in such underwriting and the inclusion of Registrable
Securities in the underwriting to the extent provided herein. All Holders
proposing to distribute their securities through such underwriting shall
(together with the Company) enter into an underwriting agreement in customary
form with the managing underwriter selected for such underwriting by the
Company. Notwithstanding any other provision of this Section 4.2, if the
managing underwriter determines that marketing factors require a limitation of
the number of shares to be underwritten and all shares of any other selling
stockholders (other than Holders of Registrable Securities) have first been
excluded from such registration, the managing underwriter may limit the
Registrable Securities and other securities to be distributed through such
underwriting; provided, however, that (i) no such reduction shall reduce the
number of Registrable Securities (other than Series E Registrable Securities and
Novation Registrable Securities) included in the registration below fifteen
percent (15%) of the total amount of securities included in such registration
("AVAILABLE 15% SHARES"); (ii) no such reduction shall reduce the number of
shares of Series E Registrable Securities included in the registration below
twelve percent (12%) of the total amount of securities included in such
registration ("AVAILABLE SERIES E SHARES"); and (iii) no such reduction shall
reduce the number of shares of Novation Registrable Securities held by VHA and
UHC, respectively, included in such registration below fifteen percent (15%) (in
the case of VHA) and five percent (5%) (in the case of UHC) of the total amount
of securities included in such registration in the case of the first and second
such underwritten offerings after the issuance of the Novation Registrable
Securities or reduce the number of shares of Novation Registrable Securities
below nine and one-half percent (9.5%) (in the case of VHA) and three and
one-half percent (3.5%) (in the case of UHC) of the total number of securities
included in any subsequent registration ("AVAILABLE NOVATION SHARES"), provided,
further that for purposes of allocating the number of Registrable Securities
(other than Series E Registrable Securities and Novation Registrable Securities)
that may be included in the aggregate number of Registrable Securities (other
than Series E Registrable Securities and Novation Registrable Securities)
constituting the Available 15% Shares, the registration and underwriting shall
be allocated such that each Holder is allowed to include in the registration and
underwriting the portion of the Available 15% Shares as is equal to (x) the
number of Registrable Securities (other than Series E Registrable Securities and
Novation Registrable Securities) which such Holder timely proposed to include in
such registration divided by (y) the number of Registrable Securities (other
than Series E Registrable Securities and Novation Registrable Securities) which
all Holders thereof timely proposed to include in such registration; provided,
further that for purposes of allocating the number of shares of Series E
Registrable Securities that may be included in the aggregate number of shares of
Series E Registrable Securities constituting the Available Series E Shares, the
registration and underwriting shall be allocated such that each Holder is
allowed to include in the registration and underwriting the portion of the
Available Series E Shares that is equal to (x) the number of shares of Series E
Registrable Securities which such Holder timely proposed to include in such
registration divided by (y) the number of Series E Registrable Securities which
all Holders thereof timely proposed to include in such registration; provided,
further that for purposes of allocating the number of Novation Registrable
Securities that may be included in the aggregate number of shares of Novation
Registrable Securities constituting the Available Novation Shares, the
registration and the underwriting shall be allocated such that each Holder is
allowed to include the portion of Available Novation Shares that is equal to (x)
the number of shares of Novation Registrable Securities which such Holder timely
proposed to include in such registration divided by (y) the number of Novation
Registrable Securities which all Holders thereof timely proposed to include in
such registration. The Company shall so advise all Holders distributing their
securities through such underwriting of such limitation and the number of
Registrable Securities that may be included in the registration and underwriting
shall be allocated to individual Holders timely requesting participation in such
registration under Section 4.2(a), (i) so that, as nearly as practicable, the
participation of each such Holder in the number of shares made available to the
Holders by the underwriters is, subject to the preceding sentence, in proportion
to (x) the number of Registrable Securities which such Holder timely proposed to
include in such registration to (y) the number of Registrable Securities which
all Holders timely proposed to include in such registration, or (ii) in such
other manner as shall be agreed to by the Company and such Holders of the
Registrable Securities proposed to be included in such registration; provided,
however, that the number of Registrable Securities to be included in such
underwriting shall not be reduced unless all other securities subject to
registration rights are first entirely excluded from such underwriting. No
Registrable Securities excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such
                                      C-53
<PAGE>   160

registration. To facilitate the allocation of shares in accordance with the
above provisions, the Company or the underwriters may round the number of shares
allocated to any Holder to the nearest 100 shares.

     If any Holder disapproves of the terms of any such underwriting, such
Holder may elect to withdraw therefrom by written notice to the Company and the
managing underwriter. Any Registrable Securities and/or other 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 (180) days after the effective date of such registration, or such
other shorter period of time as the underwriters may require.

     (c) Right to Terminate Registration. The Company shall have the right to
terminate or withdraw any registration initiated by it under this Section 4.2
prior to the effectiveness of such registration whether or not any Holder has
elected to include securities in such registration. The Registration Expenses of
such withdrawn registration shall be borne by the Company in accordance with
Section 4.4 hereof.

     4.3 Registration on Form S-3.

     (a) If the holders of at least one percent (1%) of the Registrable
Securities then outstanding or any holder of Series E Registrable Securities or
any holder of Novation Registrable Securities shall request that the Company
file a registration statement on Form S-3 (or any successor form to Form S-3 or
any similar short form registration statement), for a public offering of
Registrable Securities, the reasonably anticipated aggregate price to the public
of which would equal or exceed $1,000,000 and the Company is a registrant
entitled to use Form S-3 to register the Registrable Securities for such an
offering (or such successor or similar form), the Company shall use its best
efforts to cause such Registrable Securities to be registered on such form for
the offering and to cause such Registrable Securities to be qualified in such
jurisdictions as the Holder or Holders may reasonably request; provided,
however, that the Company shall not be required to effect more than one (1)
registration (which has been declared effective) pursuant to this Section 4.3 in
any twelve (12) month period for each of the Holders of the Registrable
Securities, the Series E Registrable Securities, and the Novation Registrable
Securities held by UHC, respectively, and the Company shall not be required to
effect more than two (2) registrations (which have been declared effective)
pursuant to this Section 4.3 in any twelve (12) month period for the Holders of
the Novation Registrable Securities held by VHA. The provisions of Section
4.1(b) shall be applicable to each registration initiated under this Section
4.3.

     (b) Notwithstanding the foregoing, the Company shall not be obligated to
take any action pursuant to this Section 4.3: (i) in any particular jurisdiction
in which the Company would be required to qualify to do business or execute a
general consent to service of process in effecting such registration,
qualification or compliance; (ii) if the Company, within ten (10) days of the
receipt of the request of the initiating Holders, gives notice of its bona fide
intention to effect the filing of a registration statement with the Commission
within ninety (90) days of receipt of such request (other than with respect to a
registration statement relating to a Rule 145 transaction, or an offering with
respect to securities issue are issuable under an employee benefit plan or other
similar plan or agreement); (iii) during the period starting with the date
ninety (90) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following, the effective date of any
registration statement pertaining to securities of the Company (other than a
registration of securities in a Rule 145 transaction or with respect to
securities issued or issuable with respect to an employee benefit plan or
similar plan or arrangement), provided that the Company is actively employing in
good faith all reasonable efforts to cause such registration statement to become
effective; or (iv) if the Company shall furnish to such Holder a certificate
signed by the President of the Company stating that in the good faith judgment
of the Board of Directors it would be seriously detrimental to the Company or
its stockholders for registration statements to be filed in the near future,
then the Company's obligation to use its best efforts to file a registration
statement shall be deferred for a period not to exceed ninety (90) days from the
receipt of the request to file such registration by such Holder; provided,
however, that the Company shall not exercise such right more than once in any
twelve (12) month period.

     4.4 Expenses of Registration. All Registration Expenses incurred in
connection with all registrations pursuant to Section 4.2, in connection with
all demand registrations under Section 4.1, and in connection with the first
three (3) S-3 registrations under Section 4.3 by each of the Series E
Registrable Securities and the Novation Registrable Securities, respectively,
shall be borne by the Company. All Selling Expenses relating to
                                      C-54
<PAGE>   161

securities registered on behalf of the Holders shall be borne by the holders of
securities included in such registration pro rata with the Company and among
each other on the basis of the number of shares so registered. Notwithstanding
the foregoing sentence, if a registration proceeding begun pursuant to Section
4.1 or 4.3 is subsequently withdrawn by the Holders, either (a) if Holders of
all of the Registrable Securities to have been registered agree, then the
Holders of the Registrable Securities to have been registered shall bear all
such Registration Expenses pro rata on the basis of the number of shares to have
been registered, or (b) if all such Holders do not agree, then the Initiating
Holders will forfeit their right to one registration pursuant to such section,
and the Company shall bear such Registration Expenses. Notwithstanding the
foregoing, however, if at the time of the withdrawal, the Holders have learned
of a material adverse change in the condition, business or prospects of the
Company from that known to the Initiating Holders at the time of their request,
of which the Company had received notice prior to the time of the request, then
the Holders shall not be required to pay any of said Registration Expenses or to
forfeit the right to one demand registration or S-3 registration, as the case
may be, and the Company shall pay the same.

     4.5 Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Section 4,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will:

          (a) Prepare and file with the Commission a registration statement with
     respect to such securities and use its best efforts to cause such
     registration statement to become and remain effective for at least one
     hundred eighty (180) days or until the earlier time that the distribution
     described in the Registration Statement has been completed, provided that
     before filing a registration statement or prospectus or any amendments or
     supplements thereto, the Company will furnish to the counsel selected by
     the holders of a majority of the Registrable Securities covered by such
     registration statement copies of all such documents proposed to be filed,
     which documents will be subject to the review of such counsel;

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

          (c) Furnish to the Holders participating in such registration and to
     the underwriters of the securities being registered such reasonable number
     of copies of the registration statement, preliminary prospectus, final
     prospectus and such other documents as such underwriters may reasonably
     request in order to facilitate the public offering of such securities.

          (d) Furnish, at the request of any Holder requesting registration of
     Registrable Securities on the date such Registrable Securities are
     delivered to the underwriters for sale in connection with a registration
     pursuant to this Section 4, (i) an opinion, dated such date, of counsel
     representing the Company for the purposes of such registration, in form and
     substance as is customarily given to underwriters in an underwritten public
     offering, addressed to the underwriters, if any, and to the Holders
     requesting registration of Registrable Securities and (ii) a letter dated
     such date, from the independent accountants of the Company, in form and
     substance as is customarily given by independent accountants to
     underwriters in an underwritten public offering, addressed to the
     underwriters, if any, and to the Holders requesting registration of
     Registrable Securities.

          (e) Use its best efforts to register and qualify the securities
     covered by such registration statement under such other securities or Blue
     Sky laws of such U.S. jurisdiction as shall be reasonably requested by the
     Holders, provided that the Company shall not be required in connection
     therein or as a condition thereto to qualify to do business or to file a
     general consent to service of process in any such states or jurisdictions.

          (f) In the event of any underwritten public offering, enter into and
     perform its obligations under an underwriting agreement, in usual and
     customary form, with the managing underwriter of such offering.

                                      C-55
<PAGE>   162

          (g) Notify each Holder 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 in the light of the
     circumstances then existing.

          (h) Cause all such Registrable Securities registered pursuant
     hereunder to be listed on each securities exchange on which similar
     securities issued by the Company are then listed and to be qualified for
     trading on each system on which similar securities issued by the Company
     are from time to time qualified.

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

          (j) make available for inspection by any underwriter participating in
     any disposition pursuant to such registration statement and any attorney,
     accountant or other agent retained by any such underwriter, all financial
     and other records, pertinent corporate documents and properties of the
     Company, and cause the Company's officers, directors, employees and
     independent accountants to supply all information reasonably requested by
     any such underwriter, attorney, accountant or agent in connection with such
     registration statement;

          (k) otherwise use its best efforts to comply with all applicable rules
     and regulations of the Securities and Exchange Commission, and make
     available to its security holders, as soon as reasonably practicable, an
     earnings statement covering the period of at least twelve months beginning
     with the first day of the Company's first full calendar quarter after the
     effective date of the registration statement, which earnings statement
     shall satisfy the provisions of Section 11(a) of the Securities Act and
     Rule 158 thereunder;

          (l) permit any holder of Registrable Securities that might be deemed,
     in the sole and exclusive judgment of such holder, to be an underwriter or
     a controlling person of the Company, to participate in the preparation of
     such registration or comparable statement and to require the insertion
     therein of material, furnished to the Company in writing, that in the
     reasonable judgment of such holder and its counsel and the Company's
     counsel should be included; and

          (m) in the event of the issuance of any stop order suspending the
     effectiveness of a registration statement, or of any order suspending or
     preventing the use of any related prospectus or suspending the
     qualification of any Registrable Securities included in such registration
     statement for sale in any jurisdiction, the Company will use its reasonable
     efforts promptly to obtain the withdrawal of such order.

If any such registration or comparable statement refers to any holder by name or
otherwise as the holder of any securities of the Company and if, in the sole and
exclusive judgment of such holder, such holder is or might be deemed to be a
controlling person of the Company, such holder shall have the right to require
(a) the inclusion in such registration statement of language, in form and
substance reasonably satisfactory to such holder, to the effect that the holding
of such securities by such holder is not to be construed as a recommendation by
such holder of the investment quality of the Company's securities covered
thereby and that such holding does not imply that such holder will assist in
meeting any future financial requirements of the Company, or (b) in the event
that such reference to such holder by name or otherwise is not required by the
Securities Act or any similar federal statute then in force, the deletion of the
reference to such holder.

     4.6 Indemnification.

     (a) The Company will indemnify each Holder, each of its officers,
directors, partners and legal counsel, and each person controlling such Holder
within the meaning of Section 15 of the Securities Act and 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),

                                      C-56
<PAGE>   163

including any of the foregoing incurred in settlement of any litigation,
commenced or threatened, arising out of or based on any of the following (each a
"VIOLATION"):

          (i) any untrue statement (or alleged untrue statement) of a material
     fact contained in any registration statement, prospectus, offering circular
     or other document, or any amendment or supplement thereto, incident to any
     such registration, qualification or compliance, or

          (ii) any omission (or alleged omission) to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein, in light of the circumstances in which they were made, not
     misleading, or

          (iii) any violation or alleged violation by the Company of the
     Securities Act, the Exchange Act or any federal or state law applicable to
     the Company in connection with any such registration, qualification or
     compliance;

and the Company will reimburse each such Holder, each of its officers,
directors, partners, and legal counsel and each person controlling 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 expense claim, loss, damage,
liability or action, provided that the Company will not be liable in any such
case to the extent that any such claim, loss, damage, liability or action 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 the Company by an instrument duly executed by such
Holder, controlling person or underwriter and stated to be specifically for use
therein, and provided further, that the indemnity agreement contained in this
Section 4.6(a) shall not apply to amounts paid in settlement of any such
expense, claim, loss, damage, liability or action if such settlement is effected
without the consent of the Company, which consent shall not be unreasonably
withheld.

     (b) Each Holder 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 the Company, each of its directors,
officers, and legal counsel, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company within the meaning of Section 15 of the Securities Act, and each
other Holder, each of its officers, directors, partners and legal counsel and
each person controlling such Holder within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages and liabilities
(or actions in respect thereof) arising out of or based on any Violation that is
contained in written information furnished to the Company by an instrument duly
executed by such Holder and stated to be specifically for use in such
registration, and will reimburse the Company, such Holders, 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 expense, claim, loss, damage, liability or action. Notwithstanding the
foregoing, the liability of each Holder under this Section 4.6(b) shall be
limited in an amount equal to the net proceeds received by such Holder of
Registrable Securities sold as contemplated herein, provided, however, that the
indemnity agreement contained in this Section 4.6(b) shall not apply to amounts
paid in settlement of any such expense loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld.

     (c) Each party entitled to indemnification under this Section 4.6 (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 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 unless the failure to give such notice
is materially prejudicial to an Indemnifying Party's ability to defend such
action, and provided, further, that the Indemnifying Party shall not assume the
defense for matters as to which there is a conflict of interest or as to which
such parties assert separate and different defenses but shall bear the expense
of such defense nevertheless.
                                      C-57
<PAGE>   164

     (d) If the indemnification provided for in this Section 4.6 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any expense, loss, liability, claim, damage, or action referred to
therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified
Party hereunder, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such expense, loss, liability, claim, damage,
or action in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party on the one hand and of the Indemnified Party on the other
in connection with the statements or omissions that resulted in such expense,
loss, liability, claim, damage, or action as well as any other relevant
equitable considerations. The relative fault of the Indemnifying Party and of
the Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party and the parties' relative intent,
knowledge and access to information. Notwithstanding the foregoing, in no event
shall the contribution by a Holder under this Section 4.6(d) exceed the net
proceeds from the offering received by such Holder, unless such Holder's
liability resulted from willful misconduct by such Holder and no person guilty
of fraudulent misrepresentation under Section 11(f) of the Securities Act shall
be entitled to contribution from a person who was not guilty of such fraudulent
misrepresentation.

     (e) The obligations of the Company and Holders under this Section 4.6 shall
survive the completion of any offering of Registrable Securities in a
registration statement under this Section 4, and otherwise.

     4.7 Information by Holder. The Holder or Holders of Registrable Securities
included in any registration shall furnish to the Company such information
regarding such Holder or Holders, the Registrable Securities held by them and
the distribution proposed by such Holder or Holders as shall be required in
connection with any registration, qualification or compliance referred to in
this Section 4.

     4.8 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 Restricted Securities, and the Novation Registrable Securities, to
the public without registration, the Company agrees to use its 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 the Company under the Securities Act and the Exchange
     Act;

          (c) Furnish to the Investor, so long as such Investor owns any
     Restricted Securities or Novation Registrable Securities, forthwith upon
     request a written statement by the Company as to its compliance with the
     reporting requirements of said Rule 144 and of the Securities Act and the
     Exchange Act, a copy of the most recent annual or quarterly report of the
     Company, and such other reports and documents of the Company and other
     information in the possession of or reasonably obtainable by the Company as
     an Investor may reasonably request in availing itself of any rule or
     regulation of the Commission allowing an Investor to sell any such
     securities without registration.

          (d) Take such actions as are necessary to enable the Holders to
     utilize Form S-3 pursuant to Section 4.3 for the sale of Registrable
     Securities.

     4.9 Transfer of Registration Rights. The rights to cause the Company to
register securities granted Holders under Sections 4.1, 4.2 and 4.3 may be
assigned by a Holder to (i) a transferee or assignee who acquires at least (or
after such transfer will hold an aggregate of) 250,000 Registrable Securities
(or 215,000 shares of Series E Registrable Securities or Novation Registrable
Securities), (ii) another Holder of Registrable Securities who already possesses
registration rights, (iii) a transferee or assignee of Registrable Securities
acquiring 10% or more of the outstanding stock of the Company, (iv) a transferee
of Registrable Securities which is a subsidiary, parent, partner, limited
partner, retired partner, shareholder or Affiliate of a Holder; (v) to a
transferee of Registrable Securities who is a Holder's family member or which is
a trust for the benefit of such Holder or (vi) in the case of Novation
Registrable Securities, patrons, affiliates, members, shareholders, partners or
controlled facilities of a shareholder, partner or member, of VHA or UHC;
provided, however, the Company is, within a reasonable time after such transfer,
furnished with written notice of the
                                      C-58
<PAGE>   165

name and address of such transferee or assignee and the securities with respect
to which such registration rights are being assigned; and provided, further,
that such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act.

     4.10 [Intentionally Omitted]

     4.11 Termination of Registration Rights. No Holder shall be entitled to
exercise any right provided for in this Section 4 after the earlier of (i)
September 30, 2005; or (ii) the time when all Registrable Securities held by
such Holder can, in the opinion of counsel to the Company, be sold by a Holder
in a three-month period without registration under the Securities Act pursuant
to Rule 144.

     4.12 No Inconsistent Agreements. The Company will not hereafter enter into
any agreement with respect to its securities that grants registration rights
that are inconsistent with or violate the rights granted to the holders of
Registrable Securities in this Agreement. Notwithstanding anything to the
contrary herein, the Company may grant registration rights in connection with
bank financings, lease lines, corporate partnering transactions, business
acquisitions of or by the Company or to entities with which the Company has a
business relationship, provided (a) such grant is not motivated primarily by
equity financing needs and (b) such grant is approved by the Board of Directors
(with the director appointed by the Series E Registrable Securities concurring
in the case of any change to the rights that are specific to the Series E
Registrable Securities, and with the director appointed from either Novation or
VHA concurring in the case of any change to the rights that are specific to the
Novation Registrable Securities). Persons granted registration rights pursuant
to the preceding sentence may become parties to part 4 of this Agreement with
the consent of the Company.

     4.13 Adjustments Affecting Registrable Securities. The Company will not
take any action, or permit any change to occur, with respect to its securities
for the purpose of materially and adversely affecting the ability of the holders
of Registrable Securities to include such Registrable Securities in a
registration undertaken pursuant to this Agreement, provided that this Section
4.13 shall not apply to actions or changes with respect to the Company's
business, balance sheet, earnings or revenue or with respect to equity, debt or
acquisition transactions involving the Company.

     7. General Provisions.

     7.1 Amendment and Waiver. Any term of this Agreement may be amended and the
observance of any term of this Agreement may be waived (either generally or in a
particular instance and either retroactively or prospectively), but only with

Novation Registrable Securities, the Holders of a majority of the Novation

Securities held by UHC; provided, however, that no amendment may adversely
affect an individual Holder differently than other similarly situated Holders
without the consent of such Holder, and provided, further, that no retroactive
amendments may be made without the approval of all parties hereto. Any amendment

each holder of any Registrable Securities at the time outstanding, each future
holder of all such securities and the Company.

     7.2 Governing Law. This Agreement shall be governed by and construed under
the laws of the State of Delaware without reference to choice of law provisions
thereof. In connection with any litigation under this Agreement, the parties

provisions of this Agreement shall inure to the benefit of, and be binding upon,
the successors, assigns, heirs, executors and administrators of the parties.

     7.4 Severability. In case any provision of this Agreement becomes or is
declared by a court of competent jurisdiction to be unenforceable, this
Agreement shall continue in full force and effect without said provision;
provided, however, that no such severability shall be effective if it materially
changes the economic benefit of this Agreement to any party.

                                                                         ANNEX D

                       FORM OF THIRD AMENDED AND RESTATED
               CERTIFICATE OF INCORPORATION OF NEOFORMA.COM, INC.

     Neoforma.com, Inc., a corporation organized and existing under the laws of
the State of Delaware, hereby certifies as follows:

          A. The name of the corporation is Neoforma.com, Inc. The original
     Certificate of Incorporation was filed with the Secretary of State of
     Delaware on August 18, 1998, originally incorporated as Neoforma, Inc.

          B. Pursuant to Section 228, 242, and 245 of the General Corporation
     Law of the State of Delaware, this Third Amended and Restated Certificate
     of Incorporation restates and integrates and further amends the Certificate
     of Incorporation of this corporation.

          C. The text of the Certificate of Incorporation is hereby amended and
     restated in its entirety to read as follows:

             ONE The name of this corporation is Neoforma.com, Inc.

             TWO The address of the registered office of the corporation in the
        State of Delaware is 15 East North Street, City of Dover, County of
        Kent, DE 19901. The name of its registered agent at that address is
        Incorporating Services, Ltd.

             THREE The purpose of the corporation is to engage in any lawful act
        or activity for which a corporation may be organized under the General
        Corporation Law of Delaware.

             FOUR This corporation is authorized to issue two classes of stock
        to be designated, respectively, "Common Stock" and "Preferred Stock."
        The total number of shares which the corporation is authorized to issue
        is 305,000,000 shares. 300,000,000 shares shall be Common Stock with a
        par value of $.001. 5,000,000 shares shall be Preferred Stock with a par
        value of $.001.

     The Board of Directors is authorized, subject to any limitations prescribed
by the law of the State of Delaware, to provide for the issuance of the shares
of Preferred Stock in one or more series, and, by filing a Certificate of
Designation pursuant to the applicable law of the State of Delaware, to
establish from time to time the number of shares to be included in each such
series, to fix the designation, powers, preferences and rights of the shares of
each such series and any qualifications, limitations or restrictions thereof,
and to increase or decrease the number of shares of any such series (but not
below the number of shares of such series then outstanding). The number of
authorized shares of Preferred Stock may also be increased or decreased (but not
below the number of shares thereof then outstanding) by the affirmative vote of
the holders of a majority of the stock of the corporation entitled to vote,
unless a vote of any other holders is required pursuant to a Certificate or
Certificates establishing a series of Preferred Stock.

     Except as otherwise expressly provided in any Certificate of Designation
designating any series of Preferred Stock pursuant to the foregoing provisions
of this Article Four, any new series of Preferred Stock may be designated, fixed
and determined as provided herein by the Board of Directors without approval of
the holders of Common Stock or the holders of Preferred Stock, or any series
thereof, and any such new series may have powers, preferences and rights,
including, without limitation, voting rights, dividend rights, liquidation
rights, redemption rights and conversion rights, senior to, junior to or pari
passu with the rights of the Common Stock, the Preferred Stock, or any future
class or series of Preferred Stock or Common Stock.

     FIVE The Board of Directors of the Corporation shall have the power to
adopt, amend or repeal the Bylaws of the corporation.

     SIX The corporation is to have perpetual existence.

                                       D-1

     SEVEN For the management of the business and for the conduct of the affairs
of the corporation, and in further definition, limitation and regulation of the
powers of the corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

          1. The conduct of the affairs of the corporation shall be managed
     under the direction of the Board of Directors. The number of directors
     shall be fixed from time to time exclusively by resolution of the Board of
     Directors.

          2. Each director shall hold office until such director's successor is
     elected and qualified, or until such director's earlier death, resignation
     or removal. No decrease in the authorized number of directors constituting
     the Board of Directors shall shorten the term of any incumbent director.

          3. Subject to the rights of the holders of any series of Preferred
     Stock, any vacancy occurring in the Board of Directors for any cause, and
     any newly created directorship resulting from any increase in the
     authorized number of directors, shall, unless (i) the Board of Directors
     determines by resolution that any such vacancies or newly created
     directorships shall be filled by the stockholders or (ii) as otherwise
     provided by law, be filled only by the affirmative vote of a majority of
     the directors then in office, although less than a quorum, or by a sole
     remaining director, and not by the stockholders. Any director elected in
     accordance with the preceding sentence shall hold office for the remainder
     of the full term of the director for which the vacancy was created or
     occurred.

          4. Subject to the rights of the holders of any series of Preferred
     Stock, any director or the entire Board of Directors may be removed by the
     holders of at least sixty-six and two-thirds percent (66 2/3%) of the
     shares then entitled to vote at an election of directors.

          5. Subject to the rights of the holders of any series of Preferred
     Stock to elect additional directors under specified circumstances, the
     directors shall be divided, with respect to the time for which they
     severally hold office, into three classes designated as Class I, Class II
     and Class III, respectively. Directors shall be assigned to each class in
     accordance with a resolution or resolutions adopted by the Board of
     Directors, with the number of directors in each class to be divided as
     equally as reasonably possible. The term of office of the Class I directors
     shall expire at the corporation's first annual meeting of stockholders
     following the closing of the corporation's initial public offering pursuant
     to an effective registration statement under the Securities Act of 1933, as
     amended, covering the offer and sale of Common Stock to the public (the
     "Initial Public Offering"); the term of office of the Class II directors
     shall expire at the corporation's second annual meeting of stockholders
     following the closing of the Initial Public Offering; and the term of
     office of the Class III directors shall expire at the corporation's third
     annual meeting of stockholders following the closing of the Initial Public
     Offering. At each annual meeting of stockholders commencing with the first
     annual meeting of stockholders following the closing of the Initial Public
     Offering, directors elected to succeed those directors of the class whose
     terms then expire shall be elected for a term of office to expire at the
     third succeeding annual meeting of stockholders after their election. In
     the event the corporation is prohibited from dividing its Board of
     Directors through the operation of Section 2115 of the California General
     Corporation Law following the record date of the corporation's first annual
     meeting of stockholders following the closing of the Initial Public
     Offering, each director shall hold office until the next annual meeting of
     stockholders and until such director's successor is elected and qualified,
     or until such director's earlier death, resignation or removal.

          6. Election of directors need not be by written ballot unless the
     Bylaws of the corporation shall so provide.

          7. No action shall be taken by the stockholders of the corporation
     except at an annual or special meeting of stockholders called in accordance
     with the Bylaws of the corporation, and no action shall be taken by the
     stockholders by written consent.

          8. Advance notice of stockholder nominations for the election of
     directors of the corporation and of business to be brought by stockholders
     before any meeting of stockholders of the corporation shall be

                                       D-2
<PAGE>   170

     given in the manner provided in the Bylaws of the corporation. Business
     transacted at special meetings of stockholders shall be confined to the
     purpose or purposes stated in the notice of meeting.

          9. Subject to Section 6.5 of the Bylaws, stockholders of the
     corporation holding at least sixty-six and two-thirds percent (66 2/3%) of
     the corporation's outstanding voting stock then entitled to vote at an
     election of directors shall have the power to adopt, amend or repeal Bylaws
     of the corporation.

          10. The affirmative vote of the holders of at least sixty-six and
     two-thirds percent (66 2/3%) of the corporation's outstanding voting stock
     then entitled to vote at an election of directors, voting together as a
     single class, shall be required to alter, change, amend, repeal or adopt
     any provision inconsistent with this Article Seven.

     EIGHT To the fullest extent permitted by the Delaware General Corporation
Law as the same exists or as may hereafter be amended, a director of the
corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director.
The corporation shall indemnify to the fullest extent permitted by law, any
person made or threatened to be made a party, to any action or proceeding,
whether criminal, civil, administrative or investigative, by reason of the fact
that he or she, or his or her testator or intestate, is or was a director or
officer of the corporation or any predecessor of the corporation, or serves or
served at any other enterprise as a director or officer at the request of the
corporation or any predecessor to the corporation. Neither any amendment nor
repeal of this Article, nor the adoption of any provision of this Certificate of
Incorporation inconsistent with this Article, shall eliminate or reduce the
effect of this Article in respect of any matter occurring, or any cause of
action, suit or claim accruing or arising or that, but for this Article, would
accrue or arise, prior to such amendment, repeal or adoption of an inconsistent
provision.

     NINE The corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation, in the manner now
or hereafter prescribed by statute, and all rights conferred upon stockholders
herein are granted subject to this reservation.

     IN WITNESS WHEREOF, the corporation has caused this Amended and Restated
Certificate to be signed by its Chief Financial Officer and Secretary, this
  day of             , 2000.
