ITEM 5: OTHER EVENTS.

     On March 30, 2000, Neoforma.com, Inc., a Delaware corporation ("Neoforma"),
Eclipsys Corporation ("Eclipsys"), a Delaware corporation, and NeoIII
Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of
Neoforma ("Merger Sub"), entered into an Agreement and Plan of Merger (the
"Eclipsys Merger Agreement"). Subject to the terms and conditions of the
Eclipsys Merger Agreement, Merger Sub will merge with and into Eclipsys, with
Eclipsys to survive the merger and become a wholly-owned subsidiary of Neoforma
(the "Eclipsys Merger"). In the Eclipsys Merger, each outstanding share of
Eclipsys common stock will be exchanged for 1.344 shares of Neoforma common
stock, and options to purchase Eclipsys common stock will be exchanged for
options to purchase shares of Neoforma common stock according to the exchange
ratio. The transaction will be structured to qualify as a tax-free
reorganization and will be accounted for as a purchase. Eclipsys stockholders
holding approximately 31% of Eclipsys' outstanding common stock, and Neoforma
stockholders holding approximately 35% of Neoforma's outstanding common stock,
have agreed to vote in favor of the Eclipsys Merger and against any proposal
made in opposition to or in competition with the Eclipsys Merger.

     On March 30, 2000, Neoforma and HEALTHvision, Inc., a Delaware corporation
("Healthvision"), entered into an Agreement and Plan of Merger (the
"Healthvision Merger Agreement"). Subject to the terms and conditions of the
Healthvision Merger Agreement, immediately following the consummation of the
Eclipsys Merger, Healthvision will merge with and into Eclipsys, which will then
be a wholly-owned subsidiary of Neoforma, with Eclipsys to survive the merger
(the "Healthvision Merger"). In the Healthvision Merger, each outstanding share
of Healthvision Series A Convertible Participating Preferred Stock will be
exchanged for 2.0801825 shares of Neoforma common stock, each outstanding share
of Healthvision Series B Convertible Preferred Stock will be exchanged for 1.776
shares of Neoforma common stock, each outstanding share of Healthvision common
stock will be exchanged for 0.444 shares of Neoforma common stock, and options
to purchase Healthvision common stock will be exchanged for options to purchase
shares of Neoforma common stock according to the common stock exchange ratio.
The transaction will be structured to qualify as a tax-free reorganization and
will be accounted for as a purchase. Healthvision stockholders holding
approximately 88% of Healthvision's outstanding voting stock, and Neoforma
stockholders holding approximately 35% of Neoforma's outstanding common stock,
have agreed to vote in favor of the Healthvision Merger and against any proposal
made in opposition to or in competition with the Healthvision Merger.

     On March 30, 2000, Neoforma, Novation LLC, a Delaware limited liability
company ("Novation"), VHA Inc., a Delaware corporation ("VHA"), University
Healthsystem Consortium, an Illinois corporation ("UHC"), and Healthcare
Purchasing Partners International, LLC, a Delaware limited liability company
("HPPI"), entered into an Outsourcing and Operating Agreement (the "Novation
Operating Agreement"), under which, subject to the terms and conditions of the
Novation Operating Agreement, each of Novation, VHA, UHC and HPPI agree to
exclusively use and promote to their member healthcare organizations Neoforma's
internet-based exchange for the purchase and sale of medical equipment, supplies
and other products and services. The term of the Novation Operating Agreement is
ten years, subject to termination or extension in accordance with its terms.
Under the Novation Operating Agreement, Neoforma will appoint Novation as
Neoforma's exclusive agent for soliciting suppliers of such products and
services on Neoforma's behalf. In connection with the Novation Operating
Agreement, Neoforma entered into Common Stock and Warrant Agreements (the "VHA
Stock and Warrant Agreement" and "UHC Stock and Warrant Agreement,"
respectively, and together with the
<PAGE>   3

Novation Operating Agreement, the "Novation Documents") with each of VHA and
UHC, Novation's member organizations, pursuant to which, and subject to the
terms and conditions of such agreements, Neoforma will issue to VHA 38.3 million
shares and warrants to purchase an additional 14.2 million shares of Neoforma
common stock, and Neoforma will issue to UHC 9.2 million shares and a warrant to
purchase an additional 1.5 million shares of Neoforma common stock.

     Upon consummation of the Eclipsys Merger, the Healthvision Merger and the
transactions contemplated by the Novation Documents, Neoforma will take all
action necessary to increase the size of the Neoforma board of directors to
nine, and appoint three directors nominated by Eclipsys, including Harvey J.
Wilson, the Chairman and CEO of Eclipsys, one director nominated by
Healthvision, and one director nominated by VHA to the Neoforma board. Following
consummation of the transactions, Harvey J. Wilson will become Chairman of the
Neoforma board of directors and Robert Zollars will continue as Chief Executive
Officer and President of Neoforma.

     Each of the transactions is subject to several conditions, including
approval by the stockholders of Neoforma, Eclipsys and Healthvision, the
expiration of applicable waiting periods under antitrust laws and obtaining
necessary consents. Each of the transactions are also subject to the
consummation of the other transactions, and may be terminated by the parties to
such transaction upon termination of either of the other transactions.

     The Eclipsys Merger Agreement, Healthvision Merger Agreement, VHA Stock and
Warrant Agreement and UHC Stock and Warrant Agreement, together with the
exhibits to such agreements, are filed as exhibits to this report. The foregoing
description is qualified in its entirety by reference to the full text of such
exhibits. A press release announcing the transactions is attached as an exhibit

                          AGREEMENT AND PLAN OF MERGER


     This AGREEMENT AND PLAN OF MERGER (this "AGREEMENT") is made and entered
into as of March 30, 2000, among Neoforma.com, Inc., a Delaware corporation
("PARENT"), NeoIII Acquisition Corp., a Delaware corporation and a wholly owned
first-tier subsidiary of Parent ("MERGER SUB"), and Eclipsys Corporation, a
Delaware corporation ("COMPANY").

     A. The respective Boards of Directors of Parent, Merger Sub and Company

with and into Company (the "MERGER") upon the terms and subject to the
conditions of this Agreement and in accordance with the General Corporation Law
of the State of Delaware ("DELAWARE LAW").

     B. For United States federal income tax purposes, the Merger is intended to

Internal Revenue Code of 1986, as amended (the "CODE"). For accounting purposes,
the Merger is intended to be accounted for as a purchase under United States
generally accepted accounting principles ("GAAP").

and inducement to Parent's willingness to enter into this Agreement, certain
stockholders of Company are entering into Voting Agreements with Parent in the
form of Exhibit A (the "COMPANY VOTING AGREEMENTS").

     D. Concurrently with the execution of this Agreement, and as a condition

     1.6 Effect on Capital Stock. Subject to the terms and conditions of this
Agreement, at the Effective Time, by virtue of the Merger and without any action
on the part of Merger Sub, Company or the holders of any of the following
securities:

         (a) Conversion of Company Common Stock. Each share of common stock, par
value $0.01 per share, of Company ("COMPANY COMMON STOCK") issued and
outstanding immediately prior to the Effective Time, other than any shares of
Company Common Stock to be canceled pursuant to Section 1.6(b), will be canceled
and extinguished and automatically converted (subject to Section 1.6(e)) into
the right to receive 1.344 (the "EXCHANGE RATIO") of a share of common stock,
par value $0.001 per share, of Parent ("PARENT COMMON STOCK") upon surrender of
the certificate representing such share of Company Common Stock in the manner
provided in Section 1.7. No fraction of a share of Parent Common Stock will be
issued by virtue of the Merger, but in lieu thereof, a cash payment shall be
made pursuant to Section 1.7(e).

         (b) Cancellation of Company-Owned and Parent-Owned Stock. Each share of
Company Common Stock held by Company or owned by Merger Sub, Parent or any
direct or indirect wholly owned subsidiary of Company or of Parent immediately
prior to the Effective Time shall be canceled and extinguished without any
conversion thereof.

         (c) Stock Options; Employee Stock Purchase Plan. At the Effective Time,
all options to purchase Company Common Stock then outstanding under Company's
1996 Stock Option Plan, 1998 Stock Incentive Plan and 1999 Stock Incentive Plan
(collectively, the "COMPANY STOCK OPTION PLANS") shall be assumed by Parent in
accordance with Section 5.9 of this Agreement. Rights outstanding under
Company's 1998 Employee Stock Purchase Plan (the "COMPANY ESPP") shall be
treated as set forth in Section 5.9 of this Agreement.

         (d) Capital Stock of Merger Sub. Each share of common stock, par value
$0.01 per share, of Merger Sub (the "MERGER SUB COMMON STOCK"), issued and
outstanding immediately prior to the Effective Time shall be converted into one
validly issued, fully paid and nonassessable share of common stock, $0.01 par
value per share, of the Surviving Corporation. Following the Effective Time,
each certificate evidencing ownership of shares of Merger Sub common stock shall
evidence ownership of such shares of capital stock of the Surviving Corporation.

         (e) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted
to reflect appropriately the effect of any stock split, reverse stock split,
stock dividend (including any dividend or distribution of securities convertible
into Parent Common Stock or Company Common Stock), reorganization,
recapitalization, reclassification or other like change with respect to Parent
Common Stock or Company Common Stock occurring on or after the date hereof and
prior to the Effective Time.

     1.7 Exchange of Certificates.

         (a) Exchange Agent. Parent shall select an institution reasonably
acceptable to Company to act as the exchange agent (the "EXCHANGE AGENT") in the
Merger.


                                      -3-
<PAGE>   8


         (b) Exchange Fund. Promptly after the Effective Time, Parent shall
deposit with the Exchange Agent for exchange in accordance with this Article I,
the shares of Parent Common Stock (such shares of Parent Common Stock, together
with cash in lieu of fractional shares and any dividends or distributions with
respect thereto, are hereinafter referred to as the "EXCHANGE FUND") issuable
pursuant to Section 1.6 in exchange for outstanding shares of Company Common
Stock.

         (c) Exchange Procedures. Promptly after the Effective Time, Parent
shall instruct the Exchange Agent to mail to each holder of record of a
certificate or certificates ("CERTIFICATES") which immediately prior to the
Effective Time represented outstanding shares of Company Common Stock whose
shares were converted into shares of Parent Common Stock pursuant to Section
1.6, (i) a letter of transmittal in customary form (that shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Exchange Agent and
shall contain such other provisions as Parent may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Parent Common Stock. Upon surrender of
Certificates for cancellation to the Exchange Agent together with such letter of
transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holders of such Certificates shall be entitled to
receive in exchange therefor certificates representing the number of whole
shares of Parent Common Stock into which their shares of Company Common Stock
were converted at the Effective Time, payment in lieu of fractional shares that
such holders have the right to receive pursuant to Section 1.7(e) and any
dividends or distributions payable pursuant to Section 1.7(d), and the
Certificates so surrendered shall forthwith be canceled. Until so surrendered,
outstanding Certificates will be deemed from and after the Effective Time, for
all corporate purposes, to evidence only the ownership of the number of full
shares of Parent Common Stock into which such shares of Company Common Stock
shall have been so converted and the right to receive an amount in cash in lieu
of the issuance of any fractional shares in accordance with Section 1.7(e) and
any dividends or distributions payable pursuant to Section 1.7(d). No interest
will be paid or accrued on any cash in lieu of fractional shares of Parent
Common Stock or on any unpaid dividends or distributions payable to holders of
Certificates. In the event of a transfer of ownership of shares of Company
Common Stock which is not registered in the transfer records of Company, a
certificate representing the proper number of shares of Parent Common Stock may
be issued to a transferee if the Certificate representing such shares of Company
Common Stock is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid.

         (d) Distributions With Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the date of this Agreement with
respect to Parent Common Stock with a record date after the Effective Time will
be paid to the holders of any unsurrendered Certificates with respect to the
shares of Parent Common Stock represented thereby until the holders of record of
such Certificates shall surrender such Certificates. Subject to applicable law,
following surrender of any such Certificates, the Exchange Agent shall deliver
to the holders of certificates representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, (i) promptly, the amount of any
cash payable with respect to a fractional share of Parent Common Stock to which
such holder is entitled pursuant to Section

                                      -4-
<PAGE>   9

1.7(e) and the amount of dividends or other distributions with a record date
after the Effective Time theretofore paid with respect to such whole shares of
Parent Common Stock, and (ii) at the appropriate payment date, the amount of
dividends or other distributions with a record date after the Effective Time but
prior to surrender and a payment date occurring after surrender, payable with
respect to such whole shares of Parent Common Stock.

         (e) Fractional Shares. (i) As promptly as practicable following the
Effective Time, the Exchange Agent shall determine the excess of (A) the number
of full shares of Parent Common Stock delivered to the Exchange Agent pursuant
to Section 1.7(b), over (B) the aggregate number of full shares of Parent Common
Stock to be distributed to holders of Company Common Stock pursuant to Section
1.7(c) (such excess, the "EXCESS SHARES"). Following the Effective Time, the
Exchange Agent, as agent for the holders of Company Common Stock, shall sell the
Excess Shares at then prevailing prices on the Nasdaq Stock Market in the manner
set forth in paragraph (ii) of this Section 1.7(e).

               (ii) The sale of the Excess Shares by the Exchange Agent shall be
executed on the Nasdaq Stock Market and shall be executed in round lots to the
extent practicable. The Exchange Agent shall use all commercially reasonable
efforts to complete the sale of the Excess Shares as promptly following the
Effective Time as, in the Exchange Agent's reasonable judgment, is practicable
consistent with obtaining the best execution of such sales in light of
prevailing market conditions. Until the net proceeds of such sales have been
distributed to the holders of Company Common Stock, the Exchange Agent will hold
such proceeds in trust for the holders of Company Common Stock. The Exchange
Agent will determine the portion of such net proceeds to which each holder of
Company Common Stock shall be entitled, if any, by multiplying the amount of the
aggregate net proceeds by a fraction the numerator of which is the amount of the
fractional share interest to which such holder of Company Common Stock is
entitled (after taking into account all shares of Parent Common Stock to be
issued to such holder) and the denominator of which is the aggregate amount of
fractional share interests to which all holders of Company Common Stock are
entitled. As soon as practicable after the determination of the amount of cash,
if any, to be paid to holders of Company Common Stock with respect to fractional
share interests, the Exchange Agent shall promptly pay such amounts to such
holders of Company Common Stock in accordance with the terms of Section 1.7(c).

               (iii) Notwithstanding the provisions of paragraphs (i) and (ii)
of this Section 1.7(e), Parent may decide, at its option, exercised prior to the
Effective Time, in lieu of the issuance and sale of Excess Shares and the making
of the payments contemplated in such paragraphs, that Parent shall pay to the
Exchange Agent an amount sufficient for the Exchange Agent to pay each holder of
Company Common Stock the amount such holder would have received pursuant to
Section 1.7(e)(ii) assuming that the sales of Parent Common Stock were made at a
price equal to the average of the closing prices of the Parent Common Stock on
the Nasdaq Stock Market for the ten consecutive trading days immediately
following the Effective Time and, in such case, all references herein to the
cash proceeds of the sale of the Excess Shares and similar references shall be
deemed to mean and refer to the payments calculated as set forth in this
paragraph (iii). In such event, Excess Shares shall not be issued or otherwise
transferred to the Exchange Agent pursuant to Sections 1.7(b) or (e).


                                      -5-
<PAGE>   10


         (f) Required Withholding. Each of the Exchange Agent, Parent and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Company Common Stock such amounts as may be required
to be deducted or withheld therefrom under the Code or under any provision of
state, local or foreign tax law or under any other applicable Legal Requirement
(as defined in Section 2.2(b)). To the extent such amounts are so deducted or
withheld, such amounts shall be treated for all purposes under this Agreement as
having been paid to the person to whom such amounts would otherwise have been
paid.

         (g) Lost, Stolen or Destroyed Certificates. In the event that any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, certificates
representing the shares of Parent Common Stock into which the shares of Company
Common Stock represented by such Certificates were converted pursuant to Section
1.6, cash for fractional shares, if any, as may be required pursuant to Section
1.7(e) and any dividends or distributions payable pursuant to Section 1.7(d);
provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance of such certificates representing shares of Parent
Common Stock, cash and other distributions, require the owner of such lost,
stolen or destroyed Certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made against
Parent, the Surviving Corporation or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

         (h) No Liability. Notwithstanding anything to the contrary in this
Section 1.7, neither the Exchange Agent, Parent, the Surviving Corporation nor
any party hereto shall be liable to a holder of shares of Parent Common Stock or
Company Common Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

         (i) Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the holders of Company Common Stock for twelve
months after the Effective Time shall be delivered to Parent, upon demand, and
any holders of Company Common Stock who have not theretofore complied with the
provisions of this Section 1.7 shall thereafter look only to Parent for the
shares of Parent Common Stock, any cash in lieu of fractional shares of Parent
Common Stock to which they are entitled pursuant to Section 1.7(e) and any
dividends or other distributions with respect to Parent Common Stock to which
they are entitled pursuant to Section 1.7(d), in each case, without any interest
thereon.

     1.8 No Further Ownership Rights in Company Common Stock. All shares of
Parent Common Stock issued in accordance with the terms hereof (including any
cash paid in respect thereof pursuant to Section 1.7(d) and (e)) shall be deemed
to have been issued in full satisfaction of all rights pertaining to such shares
of Company Common Stock, and there shall be no further registration of transfers
on the records of the Surviving Corporation of shares of Company Common Stock
that were outstanding immediately prior to the Effective Time. If after the
Effective Time Certificates are presented to the Surviving Corporation for any
reason, they shall be canceled and exchanged as provided in this Article I.


                                      -6-
<PAGE>   11


     1.9 Restricted Stock. If any shares of Company Common Stock that are
outstanding immediately prior to the Effective Time are unvested or are subject
to a repurchase option, risk of forfeiture or other condition providing that
such shares ("COMPANY RESTRICTED STOCK") may be forfeited or repurchased by the
Company upon any termination of the stockholders' employment, directorship or
other relationship with the Company (and/or any affiliate of the Company) under
the terms of any restricted stock purchase agreement or other agreement with the
Company that does not by its terms provide that such repurchase option, risk of
forfeiture or other condition lapses upon consummation of the Merger, then the
shares of Parent Common Stock issued upon the conversion of such shares of
Company Common Stock in the Merger will continue to be unvested and subject to
the same repurchase options, risks of forfeiture or other conditions following
the Effective Time, and the certificates representing such shares of Parent
Common Stock may accordingly be marked with appropriate legends noting such
repurchase options, risks of forfeiture or other conditions. Company shall take
all actions that may be necessary to ensure that, from and after the Effective
Time, Parent is entitled to exercise any such repurchase option or other right
set forth in any such restricted stock purchase agreement or other agreement. A
listing of the holders of Company Restricted Stock, together with the number of
shares and the vesting schedule of Company Restricted Stock held by each, is set
forth in Part 1.9 of the Company Disclosure Letter.

     1.10 Tax and Accounting Consequences. It is intended by the parties hereto
that the Merger shall constitute a "reorganization" within the meaning of
Section 368 of the Code. The parties hereto adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 354(a) and 361(a) of the Code and
Treas. Reg. Sections 1.368-2(g) and 1.368-3(a). It is intended by the parties
that the Merger shall qualify for accounting treatment as a purchase.

     1.11 Taking of Necessary Action; Further Action. If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Company and Merger Sub, the officers and directors of Company
and Merger Sub will take all such lawful and necessary action. Parent shall
cause Merger Sub to perform all of its obligations relating to this Agreement
and the transactions contemplated hereby.

organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all requisite corporate power and
authority, and all requisite qualifications to do business as a foreign
corporation, to conduct its business in the manner in which its business is
currently being conducted, except where the failure to be so organized, existing

not, individually or in the aggregate, have a Material Adverse Effect (as
defined in Section 8.3) on Company.

         (b) Other than the corporations identified in Part 2.1 of the Company
Disclosure Letter, neither Company nor any of the other corporations identified
in Part 2.1 of the Company Disclosure Letter owns any capital stock of, or any

Neither Company nor any of its subsidiaries is obligated to make any material

the Company Charter Documents.

     2.2 Company Capitalization.

         (a) The authorized capital stock of Company consists solely of
200,000,000 shares of Company Common Stock, of which there were 36,530,325

the Company Stock Option Plans. All shares of Company Common Stock subject to
issuance as aforesaid, upon issuance on the terms and conditions specified in
the instruments pursuant to which they are issuable, will be duly authorized,
validly issued, fully paid and nonassessable. Other than as set forth on Part
2.2(b) of the Company Disclosure Letter, there are no commitments or agreements
of any character to which the Company is bound obligating Company to accelerate
the vesting of any Company Option as a result of the Merger.

         (c) All outstanding shares of Company Common Stock, all outstanding
Company Options, and all outstanding shares of capital stock of each subsidiary
of Company have been issued and granted in material compliance with (i) all

(other than (i) liens for Taxes (as defined in Section 2.7) not yet due and

     2.4 Authority; Non-Contravention.

         (a) Company has all requisite corporate power and authority to enter
into this Agreement and to consummate the transactions contemplated hereby. The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Company, subject only to the approval and
adoption of this Agreement and the approval of the Merger by Company's
stockholders (the "COMPANY STOCKHOLDER APPROVALS") and the filing of the
Certificate of Merger pursuant to Delaware Law. The affirmative vote of the
holders of a majority of the outstanding shares of Company Common Stock is
sufficient for Company's stockholders to approve and adopt this Agreement and
approve the Merger, and no other approval of any holder of any securities of
Company is required in connection with the consummation of the transactions
contemplated hereby. This Agreement has been duly executed and delivered by
Company and, assuming the due execution and delivery by Parent and Merger Sub,
constitutes the valid and binding obligation of Company, enforceable against
Company in accordance with its 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 by Company does not,
and the performance of this Agreement by Company will not, (i) conflict with or

         (f) Multiemployer Plans. At no time has Company contributed to or been
required to contribute to any Multiemployer Plan.

         (g) No Post-Employment Obligations. No Company Employee Plan provides,
or has any liability to provide, retiree life insurance, retiree health or other
retiree employee welfare benefits to any person for any reason, except as may be
required by COBRA or other applicable statute, and Company has never
represented, promised or contracted (whether in oral or written form) to any
Employee (either individually or to Employees as a group) or any other person

occurrence of any additional or subsequent events) constitute an event under any
Company Employee Plan, Employee Agreement, trust or loan that will or may result
in any payment (whether of severance pay or otherwise), acceleration,
forgiveness of indebtedness, vesting, distribution, increase in benefits or
obligation to fund benefits with respect to any Employee. No payment or benefit
which will or may be made by Company or its Affiliates with respect to any
Employee as a result of the transactions contemplated by this Agreement will be
characterized as an "excess parachute payment," within the meaning of Section
280G(b)(1) of the Code or will be treated as a nondeductible expense within the
meaning of Section 162 of the Code.

         (j) Employment Matters. Except, in each case, as would not,
individually or in the aggregate, have a Material Adverse Effect on Company,
Company and each of its subsidiaries: (i) is in compliance in all material
respects with all applicable foreign, federal, state and local laws, rules and
regulations respecting employment, employment practices, terms and conditions of
employment and wages and hours, in each case, with respect to Employees; (ii)

pending, or, to Company's knowledge, threatened material claims or actions
against Company under any worker's compensation policy or long-term disability
policy. To Company's knowledge, no Employee of Company has violated in any

noncompetition agreement by which such Employee is bound due to such Employee
being employed by Company and disclosing to Company or using trade secrets or
proprietary information of any other person or entity.

         (k) Labor. No work stoppage or labor strike against Company is pending,
threatened or reasonably anticipated. Company does not know of any activities or
proceedings of any labor union to organize any Employees. There are no actions,
suits, claims, labor disputes or grievances pending, or, to the knowledge of
Company, threatened relating to any labor, safety or discrimination matters
involving any Employee, including charges of unfair labor practices or
discrimination complaints, which, if adversely determined, would, individually
or in the aggregate, result in any material liability to Company. Neither
Company nor any of its subsidiaries has engaged in any unfair labor practices
within the meaning of the National Labor Relations Act. Company is not
presently, nor has it been in the past, a party to, or bound by, any collective
bargaining agreement or union contract with respect to Employees and no
collective bargaining agreement is being negotiated by Company.

         (l) International Employee Plan. Each International 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 Employee
Plan. Furthermore, no International Employee Plan has unfunded liabilities, that
as of the Effective Time, will not be offset by insurance or fully

                                      -21-
<PAGE>   26

accrued. Except as required by law, no condition exists that would prevent
Company or Parent from terminating or amending any International Employee Plan
at any time for any reason.

     2.13 Environmental Matters. During the period that Company 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 Company. Company 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 Company 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 Company. None of the properties or facilities
currently leased or owned by Company or any of its subsidiaries or any
properties or facilities previously leased or owned by Company 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 Company. During Company's occupancy of any properties
or facilities owned or leased at any time by Company, neither Company, nor to
Company'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
Company. During the time that Company 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 Company or any of its subsidiaries, there
has been no material litigation, proceeding or administrative action brought or
threatened against Company or any of its subsidiaries, or any material
settlement reached by Company 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.

the transactions contemplated hereby and thereby have been duly authorized by
all necessary corporate action on the part of Parent and Merger Sub, subject
only to the Parent Stockholder Approvals and the filing of the Certificate of

issuance of shares of Parent Common Stock in the Merger and pursuant to the
Related Agreements, and the affirmative vote of the holders of a majority of the
outstanding shares of Parent Common Stock entitled to vote is sufficient for
Parent's stockholders to approve the amendment to Parent's Certificate of
Incorporation, and no other approval of any holder of any securities of Parent
is required in connection with the consummation of the transactions contemplated
hereby. This Agreement and the Related Agreements have been duly executed and
delivered by each of Parent and Merger Sub, as applicable, and, assuming the due
authorization, execution and delivery by Company or the other parties thereto,
constitute the valid and binding obligations of Parent and Merger Sub,
respectively, enforceable against Parent and Merger Sub 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 Related
Agreements by each of Parent and Merger Sub does not, and the performance of
this Agreement and the Related Agreements by Parent and Merger Sub will not, (i)
conflict with or violate the Parent Charter Documents, (ii) subject to obtaining
the Parent Stockholder Approvals and compliance with the requirements set forth
in Section 3.4(c), conflict with or violate any law, rule, regulation, order,
judgment or decree applicable to Parent or Merger Sub or by which any of their
respective properties is 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 Parent'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 Parent or
Merger Sub pursuant to, any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which Parent or Merger Sub is a party or by which Parent or Merger Sub or any
of their respective 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 Parent. Part 3.4(b) of the Parent Disclosure Letter
lists all consents, waivers and approvals under any of Parent's or any of its
subsidiaries' agreements, contracts, licenses or leases 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 Parent,

with the SEC and a Schedule 13D with regard to the Company Voting Agreements in
accordance with the Securities Act and the Exchange Act, and the effectiveness
of the Registration Statement, (iii) 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 (iv) such
other consents, authorizations, filings, approvals and registrations which if
not obtained or made would not have a Material Adverse Effect on Parent or the
Surviving Corporation or have a material adverse effect on the ability of the
parties hereto to consummate the Merger.

     3.5 SEC Filings; Parent Financial Statements.

for any reason.

owned its properties or leased, owned or operated any facilities, there have

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

         (b) Subject to Section 5.2(c), to the fullest extent permitted by
applicable law: (i) the Board of Directors of Company shall recommend that
Company's stockholders vote in favor of and adopt and approve this Agreement and
approve the Merger at the Company Stockholders' Meeting; (ii) the Proxy
Statement/Prospectus shall include a statement to the effect that the Board of
Directors of Company has recommended that Company's stockholders vote in favor
of and adopt and approve this Agreement and the Merger at the Company
Stockholders' Meeting; and (iii) neither the Board of Directors of Company nor
any committee thereof shall withdraw, amend or modify, or propose or resolve to
withdraw, amend or modify in a manner adverse to Parent, the recommendation of
the Board of Directors of Company that Company's stockholders vote in favor of
and adopt and approve this Agreement and the Merger.

         (c) Nothing in this Agreement shall prevent the Board of Directors of
the Company from withholding, withdrawing, amending or modifying its
recommendation in favor

                                      -48-
<PAGE>   53

of the Merger if (i) a Superior Offer (as defined below) is made to the Company
and is not withdrawn, (ii) the Company shall have provided written notice to
Parent (a "NOTICE OF SUPERIOR OFFER") advising Parent that the Company 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) Parent shall not have, within three business days of Parent's
receipt of the Notice of Superior Offer, made an offer that the Company'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 Company's stockholders as such Superior Offer (it being agreed that
the Board of Directors of Company shall convene a meeting to consider any such
offer by Parent promptly following the receipt thereof), (iv) the Board of
Directors of Company 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 Company to comply with its fiduciary
obligations to Company's stockholders under applicable law and (v) Company shall
not have violated any of the restrictions set forth in Section 5.4 or this
Section 5.2. Company shall provide Parent with at least one day prior notice (or
such lesser prior notice as provided to the members of the Company's Board of
Directors) of any meeting of the Company's Board of Directors at which Company's
Board of Directors is reasonably expected to consider any Acquisition Proposal
(as defined in Section 5.4) to determine whether such Acquisition Proposal is a
Superior Offer. Nothing contained in this Section 5.2(c) shall limit the
Company's obligation to hold and convene the Company Stockholders' Meeting
(regardless of whether the recommendation of the Board of Directors of Company
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 Company
pursuant to which the stockholders of Company 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 the Company), directly or indirectly, of ownership of 100% of
the then outstanding shares of capital stock of the Company, on terms that the
Board of Directors of the Company determines, in its reasonable judgment (after
consultation with a financial advisor of national standing) to be more favorable
to the Company stockholders than the terms of the Merger; 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 the Company'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 Company 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 Exchange Act, or
otherwise required by applicable law.

     5.3 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 declaration of effectiveness of the
Registration Statement (provided that Company and Parent will notice the Company
Stockholders' Meeting and the Parent Stockholders' Meeting to be held on the
same day, and if Company adjourns or postpones the Company Stockholders'
Meeting, Parent may adjourn or postpone the Parent Stockholders' Meeting in
order that they be held on the same day), for the purpose of voting upon the
Parent Stockholder Approvals. Parent will use its commercially reasonable
efforts to solicit from its stockholders proxies in favor of the approval of the
Parent Stockholder Approvals 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 or Delaware Law to obtain such approvals.
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/Prospectus 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/Prospectus) 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) (i) The Board of Directors of Parent shall recommend that Parent's
stockholders approve the Parent Stockholder Approval at the Parent Stockholders'
Meeting; (ii) the Proxy Statement/Prospectus 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 Company
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 Company, the recommendation of
the Board of Directors of Parent that Parent's stockholders approve the Parent
Stockholder Approval.

         (c) 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 Exchange Act, or
otherwise required by applicable law.

     5.4 No Solicitation.

         (a) From and after the date of this Agreement until the Effective Time
or termination of this Agreement pursuant to Article VII, Company 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,

                                      -50-
<PAGE>   55

directly or indirectly, (i) solicit, initiate, encourage or induce the making,
submission or announcement of any 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
Acquisition Proposal, (iii) engage in discussions with any person with respect
to any Acquisition Proposal, except as to the existence of these provisions,
(iv) approve, endorse or recommend any 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 Acquisition Proposal;
provided, however, that prior to the approval of this Agreement and the Merger
at the Company Stockholders' Meeting, Company may furnish nonpublic information
regarding Company and its subsidiaries to, or entering into discussions or
negotiations with, any person or group who has submitted (and not withdrawn) to
Company an unsolicited, written, bona fide Acquisition Proposal that the Board
of Directors of Company reasonably concludes (after consultation with a
financial advisor of national standing) may constitute a Superior Offer if (1)
neither Company nor any representative of Company and its subsidiaries shall
have violated any of the restrictions set forth in this Section 5.4, (2) the
Board of Directors of Company concludes in good faith, after consultation with
its outside legal counsel, that such action is required in order for the Board
of Directors of Company to comply with its fiduciary obligations to Company'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, Company gives Parent written notice of the identity of such
person or group and all of the material terms and conditions of such Acquisition
Proposal and of Company's intention to furnish nonpublic information to, or
enter into discussions with, such person or group, and Company receives from
such person or group an executed confidentiality agreement containing terms at
least as restrictive with regard to Company's confidential information as the
Confidentiality Agreement (as defined in Section 5.5), and (4) contemporaneously
with furnishing any such nonpublic information to such person or group, Company
furnishes such nonpublic information to Parent (to the extent such nonpublic
information has not been previously furnished by the Company to Parent). Company
and its subsidiaries will immediately cease any and all existing activities,
discussions or negotiations with any parties conducted heretofore with respect
to any 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 Company or any of its subsidiaries or
any investment banker, attorney or other advisor or representative of Company or
any of its subsidiaries shall be deemed to be a breach of this Section 5.4 by
Company.

         For purposes of this Agreement, "ACQUISITION PROPOSAL" shall mean any
offer or proposal (other than an offer or proposal by Parent) relating to any
transaction or series of related transactions other than the transactions
contemplated by this Agreement involving: (A) any acquisition or purchase from
the Company by any person or "group" (as defined under Section 13(d) of the
Exchange Act and the rules and regulations thereunder) of more than a 15%
interest in the total outstanding voting securities of the Company or any of its
subsidiaries or any tender offer or exchange offer that if consummated would
result in any person or "group" (as defined under Section 13(d) of the Exchange
Act and the rules and regulations thereunder) beneficially owning 15% or more of
the total outstanding voting securities of the Company or any of its
subsidiaries or any merger, consolidation, business combination or similar
transaction involving

                                      -51-
<PAGE>   56

the Company pursuant to which the stockholders of the Company immediately
preceding such transaction hold less than 85% of the equity interests in the
surviving or resulting entity of such transaction; (B) any sale, lease (other
than in the ordinary course of business), exchange, transfer, license (other
than in the ordinary course of business), acquisition, or disposition of more
than 15% of the assets of the Company; or (C) any liquidation or dissolution of
the Company.

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

     5.5 Confidentiality; Access to Information.

         (a) The parties acknowledge that Company and Parent have previously
executed a mutual nondisclosure agreement, dated as of March 5, 2000 (the
"CONFIDENTIALITY AGREEMENT"), which Confidentiality Agreement will continue in
full force and effect in accordance with its terms; provided, that nothing in
this Agreement or the Confidentiality Agreement will restrict communications
with parties to the Related Agreements.

         (b) Access to Information. Company will afford Parent and its
accountants, counsel and other representatives reasonable access during normal
business hours to the properties, books, records and personnel of Company during
the period prior to the Effective Time to obtain all information concerning the
business, including the status of product development efforts, properties,
results of operations and personnel of Company, as Parent may reasonably
request. Parent will afford Company and its accountants, counsel and other
representatives reasonable access during normal business hours to the
properties, books, records and personnel of Parent during the period prior to
the Effective Time to obtain all information concerning the business, including
the status of product development efforts, properties, results of operations and
personnel of Parent, as Company may reasonably request. No information or
knowledge obtained in any investigation pursuant to this Section 5.5 will affect
or be deemed to modify any representation or warranty contained herein or the
conditions to the obligations of the parties to consummate the Merger.

     5.6 Public Disclosure. Parent and Company 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 the Merger, this Agreement or any
Acquisition Proposal 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 joint press release announcing the signing of this
Agreement.

     5.7 Reasonable Efforts; Notification.

         (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 parties in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Merger and the other transactions contemplated by this
Agreement and the Related Agreements, including using reasonable efforts to
accomplish the following: (i) the taking of all reasonable acts necessary to
cause the conditions precedent set forth in Article VI 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 material assets or
categories of assets of Parent, any of its affiliates or Company or the holding
separate of the shares of Company Common Stock (or shares of stock of the
Surviving Corporation) or imposing or seeking to impose any material limitation
on the ability of Parent or any of its subsidiaries or affiliates to conduct
their business or own such assets or to acquire, hold or exercise full rights of
ownership of the shares of Company Common Stock (or shares of stock of the
Surviving Corporation).

         (b) Each of Company 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 Merger, (ii) any
notice or other communication from any Governmental Entity in connection with
the Merger, (iii) any litigation relating to, involving or otherwise affecting
Company, Parent or their respective subsidiaries that relates to the
consummation of the Merger. Company 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 Company 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 Section 6.3 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 Company of any
representation or warranty made by it or Merger Sub contained in this Agreement
becoming untrue or inaccurate, or any failure of Parent or Merger Sub to comply
with or satisfy in any material respect any covenant, condition or agreement to
be complied with

                                      -53-
<PAGE>   58

or satisfied by it under this Agreement, in each case, such that the conditions
set forth in Section 6.2 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.

     5.8 Third Party Consents. As soon as practicable following the date hereof,
Parent and Company 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. As soon as practicable following the date hereof, Parent will 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 by the Related Agreements.

     5.9 Stock Options and ESPP.

         (a) At the Effective Time, each outstanding Company Option, whether or
not then exercisable, will be assumed by Parent. Each Company Option so assumed
by Parent under this Agreement will continue to have, and be subject to, the
same terms and conditions set forth in the Company Stock Option Plan pursuant to
which such Company Option was issued immediately prior to the Effective Time
(including, without limitation, any repurchase rights or vesting provisions),
except that (i) each Company Option will be exercisable (or will become
exercisable in accordance with its terms) for that number of whole shares of
Parent Common Stock equal to the product of the number of shares of Company
Common Stock that were issuable upon exercise of such Company Option immediately
prior to the Effective Time multiplied by the Exchange Ratio, rounded down to
the nearest whole number of shares of Parent Common Stock and (ii) the per share
exercise price for the shares of Parent Common Stock issuable upon exercise of
such assumed Company Option will be equal to the quotient determined by dividing
the exercise price per share of Company Common Stock at which such Company
Option was exercisable immediately prior to the Effective Time by the Exchange
Ratio, rounded up to the nearest whole cent. Continuous employment with Company
or its subsidiaries shall be credited to the optionee for purposes of
determining the vesting of all assumed Company Options after the Effective Time.

         (b) It is intended that Company Options assumed by Parent shall qualify
following the Effective Time as incentive stock options as defined in Section
422 of the Code to the extent Company Options qualified as incentive stock
options immediately prior to the Effective Time and the provisions of this
Section 5.9 shall be applied consistent with such intent.

         (c) Company shall take all actions necessary pursuant to the terms of
the Company ESPP in order to terminate the Company ESPP and each "Option" (as
defined in the Company ESPP) thereunder immediately prior to the Effective Time;
provided, that Company will give advance notice of such termination to each
holder of an Option not less than ten days preceding such termination, and each
holder of an Option shall have the right to exercise such

                                      -54-
<PAGE>   59

Option in full based on such holder's payroll deductions then credited to such
holder's account as of the date determined by the Board of Directors of Company.

         (d) Prior to the grant of any Company Options permitted under Section
4.1(f), Company agrees to amend the Company Stock Option Plans to eliminate for
all Company Options granted after the date of this Agreement the acceleration of
the vesting of such Company Options upon consummation of the Merger or the other
transactions contemplated hereby. Company agrees to use its best efforts to
cause the holders of Company Options under the Company's 1999 Stock Incentive
Plan to waive any acceleration of the vesting of such Company Options upon
consummation of the Merger or the transactions contemplated by the Related
Agreements. Parent agrees to use its best efforts to cause the holders of Parent
Options to waive any acceleration of the vesting of such Parent Options upon
consummation of the Merger or the transactions contemplated by the Related
Agreements.

     5.10 Form S-8. Parent agrees to file a registration statement on Form S-8
for the shares of Parent Common Stock issuable with respect to assumed Company
Options as soon as is reasonably practicable after the Effective Time and shall
maintain the effectiveness of such registration statement thereafter for so long
as any of such options or other rights remain outstanding.

     5.11 Indemnification.

         (a) From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of Company
pursuant to any indemnification agreements between Company and its directors and
officers as of the Effective Time (the "INDEMNIFIED PARTIES") and any
indemnification provisions under Company's Certificate of Incorporation or
Bylaws as in effect on the date hereof. The Certificate of Incorporation and
Bylaws of the Surviving Corporation will contain provisions with respect to
exculpation and indemnification that are at least as favorable to the
Indemnified Parties as those contained in the Certificate of Incorporation and
Bylaws of Company as in effect on the date hereof, which provisions will not be
amended, repealed or otherwise modified for a period of six years from the
Effective Time in any manner that would adversely affect the rights thereunder
of individuals who, immediately prior to the Effective Time, were directors or
officers of Company, unless such modification is required by law.

         (b) For a period of six years after the Effective Time, Parent will
cause the Surviving Corporation to use its commercially reasonable efforts to
maintain in effect, if available, directors' and officers' liability insurance
covering those persons who are currently covered by Company's directors' and
officers' liability insurance policy on terms comparable to those applicable to
the current directors and officers of Company; provided, however, that in no
event will Parent or the Surviving Corporation be required to expend in excess
of 200% of the annual premium currently paid by Company for such coverage (or
such coverage as is available for such 200% of such annual premium).

         (c) This Section 5.11 shall survive the consummation of the Merger, is
intended to benefit Company, the Surviving Corporation and each Indemnified
Party, shall be

                                      -55-
<PAGE>   60

binding on all successors and assigns of the Surviving Corporation and Parent,
and shall be enforceable by the Indemnified Parties.

     5.12 Parent Board of Directors; Executive Officers. The Board of Directors
of Parent will take all actions reasonably necessary such that as soon as
practicable following the Effective Time, (i) the size of Parent's Board of
Directors shall be increased to nine, and the following persons shall be
appointed to Parent's Board of Directors to fill the five vacancies in the
following classes: three persons nominated by Company, one of whom shall be
Harvey J. Wilson, who shall be appointed to Class III, one of whom shall be
affiliated with General Atlantic Partners, LLC, who shall be appointed to Class
I, and the other of whom shall be appointed to Class II, one person shall be
appointed by Healthvision to Class I, and one person shall be appointed by VHA
to Class I, and (ii) Harvey J. Wilson shall be elected Chairperson of the Board
of Directors of Parent, and Robert Zollars shall be elected Chief Executive
Officer and President of Parent. Under the Parent 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, or, if such annual meeting is held following the Effective Time
and such person so elects, following the Effective Time but prior to such annual
meeting. Class I Directors appointed following such annual meeting shall have
terms that end in 2003, subject to such directors' earlier resignation or
removal.

     5.13 Nasdaq Listing. Parent agrees to authorize for listing on the Nasdaq
Stock Market the shares of Parent Common Stock issuable, and those required to
be reserved for issuance, in connection with the Merger, effective upon official
notice of issuance.

     5.14 Letters of Accountants. Company and Parent shall use their respective
reasonable efforts to cause to be delivered to Parent a letter of Company's and
Parent's independent accountants, respectively, dated no more than two business
days before the date on which the Registration Statement becomes effective (and
satisfactory in form and substance to Company and Parent), that is customary in
scope and substance for letters delivered by independent public accountants in
connection with registration statements similar to the Registration Statement.

     5.15 Takeover Statutes. If any Takeover Statute is or may become applicable
to the Merger or the other transactions contemplated by this Agreement, each of
Parent and Company 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.

     5.16 Certain Employee Benefits. As soon as practicable after the execution
of this Agreement, Parent and Company shall confer and work together in good
faith to agree upon mutually acceptable employee benefit and compensation
arrangements which carry out the agreements set forth in the following two
sentences. Parent will use reasonable efforts to arrange that, as soon as
reasonably practicable after the Effective Time, Parent's benefit arrangements
and employee plans provide similar or comparable benefits to Company's employees
generally

                                      -56-
<PAGE>   61

as is provided to Parent's employees who are similarly situated. Parent's
benefit arrangements and employee plans shall give full credit for each
participant's continuous period of service with Company prior to the Effective
Time for all purposes for which length of service prior to the Effective Time is
recognized under Parent benefit arrangements and employee plans. At Parent's
request, Company agrees that it and its subsidiaries shall terminate any and all
Company Employee Plans, if appropriate (other than contractual agreements
disclosed in the Company Disclosure Letter) immediately prior to the Effective
Time.

     5.17 Registration Rights. Parent agrees to use its reasonable efforts to
cause the holders of existing registration rights regarding Parent Common Stock
to surrender their existing registration rights in exchange for the registration
rights provided under the Registration Rights Agreement attached hereto as
Schedule 5.17 (the "NEW PARENT REGISTRATION RIGHTS AGREEMENT"). Company agrees
to use its reasonable efforts to cause the holders of existing registration
rights regarding Company Common Stock to surrender their existing rights in
exchange for the registration rights provided to such party under the New Parent
Registration Rights Agreement. Upon receipt by Parent of a valid termination of
all Company registration rights held by a party, Parent shall grant to such
party the registration rights set forth in the New Parent Registration Rights
Agreement applicable to such party.

     5.18 Acquisitions of Company Stock. From the date of this Agreement through
the earlier of the Effective Time or the termination of this Agreement in
accordance with its terms, Parent agrees that it will not purchase shares of
Company Common Stock or otherwise intentionally acquire the right to vote shares
of Company Common Stock, without the Company's consent.

<PAGE>   65


         (b) by either Company or Parent if the Merger shall not have been
consummated by September 30, 2000 for any reason; provided, however, that the
right to terminate this Agreement under this Section 7.1(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 Merger to occur on or before such date and

         (c) by either Company or Parent 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
Merger, which order, decree, ruling or other action is final and nonappealable;

         (d) by either Company or Parent, if the approval and adoption of this
Agreement, and the approval of the Merger, by the stockholders of Company shall
not have been obtained by reason of the failure to obtain the required vote at a
meeting of Company stockholders duly convened therefore or at any adjournment
thereof; provided, however, that the right to terminate this Agreement under
this Section 7.1(d) shall not be available to Company where the failure to
obtain the Company stockholder approval shall have been caused by the action or
failure to act of Company and such action or failure to act constitutes a
material breach by Company of this Agreement;

         (e) by either Company or Parent, if the approval of the issuance of
shares of Parent Common Stock pursuant to the Merger shall not have been

         (g) by Company, upon a breach of any representation, warranty, covenant

such that the conditions set forth in Section 6.2(a) or Section 6.2(b) would not
be satisfied as of the time of such breach or as of the time such representation
or warranty shall have become untrue, provided that if such inaccuracy in
Parent's representations and warranties or breach by Parent is curable by Parent
through the exercise of its commercially reasonable efforts, then Company may
not terminate this Agreement under this Section 7.1(g) for 30 days after
delivery of written notice from Company to Parent of such breach, provided
Parent continues to exercise commercially reasonable efforts to cure such

                                      -61-

or agreement on the part of Company set forth in this Agreement, or if any
representation or warranty of Company shall have become untrue, in either case
such that the conditions set forth in Section 6.3(a) or Section 6.3(b) would not
be satisfied as of the time of such breach or as of the time such representation
or warranty shall have become untrue, provided that if such inaccuracy in
Company's representations and warranties or breach by Company is curable by
Company through the exercise of its commercially reasonable efforts, then Parent
may not terminate this Agreement under this Section 7.1(h) for 30 days after
delivery of written notice from Parent to Company of such breach, provided
Company continues to exercise commercially reasonable efforts to cure such
breach (it being understood that Parent may not terminate this Agreement
pursuant to this paragraph (h) if such breach by Company is cured during such
30-day period, or if Parent shall have materially breached this Agreement); or

         (i) by either Company or Parent, if any of the Related Agreements has
been validly terminated by a party thereto in accordance with its terms.

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

modified in a manner adverse to Parent its recommendation in favor of the

first published sent or given, a statement disclosing that Company recommends
rejection of such tender or exchange offer.

     7.2 Notice of Termination Effect of Termination. Any proper termination of
this Agreement under Section 7.1 above will be effective immediately upon the
delivery of written notice of the terminating party to the other parties hereto.
In the event of the termination of this Agreement as provided in Section 7.1,
this Agreement shall be of no further force or effect, except (i) as set forth
in this Section 7.2, Section 7.3 and Article 8, each of which shall survive the
termination of this Agreement, and (ii) nothing herein shall relieve any party
from liability

                                      -62-
<PAGE>   67

for any willful breach of this Agreement. No termination of this Agreement shall
affect the obligations of the parties contained in the Confidentiality
Agreement, all of which obligations shall survive termination of this Agreement
in accordance with its terms.

     7.3 Fees and Expenses.

         (a) General. Except as set forth in this Section 7.3, all fees and
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses whether
or not the Merger is consummated; provided, however, that Parent, Company and
Healthvision shall share equally all fees and expenses, other than attorneys'
and accountants fees and expenses, incurred in relation to the preparation and
filing with the SEC of the Proxy Statement/Prospectus (including any preliminary
materials related thereto) and the Registration Statement (including financial
statements and exhibits) and any amendments or supplements thereto, provided,
that Parent and Company shall share equally the expenses of printing the
finalized Proxy Statement/Prospectus (including any preliminary materials
related thereto) and any supplements thereto.

         (b) Company Payments. In the event that this Agreement is terminated by
Parent or the Company, as applicable, pursuant to Sections 7.1(d), 7.1(f) or
7.1(h), Company shall promptly, but in no event later than two days after the
date of such termination, pay Parent a fee equal to $50 million in immediately
available funds; provided, that in the case of a termination under Sections
7.1(d) or 7.1(h) prior to which no Triggering Event has occurred, (i) such
payment shall be made only if (A) following the date of this Agreement and prior
to the termination of this Agreement, a person has publicly announced a bona
fide Acquisition Proposal and (B) within nine months following the termination
of this Agreement either a Company Acquisition (as defined below) is
consummated, or the Company enters into an agreement providing for a Company
Acquisition and such Company 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 the Company has entered into such an agreement within
such nine-month period) and (ii) such payment shall be made promptly, but in no
event later than two days after the consummation of such Company Acquisition
(regardless of when such consummation occurs if the Company has entered into
such an agreement within such nine-month period). Company acknowledges that the
agreements contained in this Section 7.3(b) are an integral part of the
transactions contemplated by this Agreement, and that, without these agreements,
Parent would not enter into this Agreement. Accordingly, if the Company fails to
pay in a timely manner the amounts due pursuant to this Section 7.3(b), and, in
order to obtain such payment, Parent makes a claim that results in a judgment
against the Company for the amounts set forth in this Section 7.3(b), Company
shall pay to Parent 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 7.3(b) at the prime rate of
The Chase Manhattan Bank in effect on the date such payment was required to be
made. Payment of the fees described in this Section 7.3(b) shall not be in lieu
of damages incurred in the event of breach of this Agreement.

         For the purposes of this Agreement, "COMPANY ACQUISITION" shall mean
any of the following transactions (other than the transactions contemplated by
this Agreement); (i) a

                                      -63-
<PAGE>   68

merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving the Company pursuant to which the
stockholders of the Company immediately preceding such transaction hold less
than 50% of the aggregate equity interests in the surviving or resulting entity
of such transaction, (ii) a sale or other disposition by the Company of assets
representing in excess of 50% of the aggregate fair market value of the
Company's business immediately prior to such sale, or (iii) the acquisition by
any person or group (including by way of a tender offer or an exchange offer or
issuance by Company), directly or indirectly, of beneficial ownership or a right
to acquire beneficial ownership of shares representing in excess of 50% of the
voting power of the then outstanding shares of capital stock of the Company.

     7.4 Amendment. Subject to applicable law, this Agreement may be amended by
the parties hereto at any time by execution of an instrument in writing signed
on behalf of each of Parent and Company. Parent will not agree to any amendment
of any Related Agreement without the prior written consent of Company (which
consent shall not be unreasonably withheld or delayed).

     7.5 Extension; Waiver. At any time prior to the Effective Time any party
hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties hereto,
(ii) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto and (iii)
waive compliance with any of the agreements or conditions for the benefit of
such party contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such party. Delay in exercising any right under this
Agreement shall not constitute a waiver of such right.

     8.3 Interpretation; Certain Defined Terms.

         (a) When a reference is made in this Agreement to Exhibits, such
reference shall be to an Exhibit to this Agreement unless otherwise indicated.
When a reference is made in this Agreement to Sections, such reference shall be
to a Section of this Agreement unless otherwise indicated. The words "INCLUDE,"
"INCLUDES" and "INCLUDING" when used herein shall be deemed in each case to be
followed by the words "WITHOUT LIMITATION." The table of contents and headings
contained in this Agreement are for reference purposes only and shall not affect
in

                                      -65-
<PAGE>   70

any way the meaning or interpretation of this Agreement. When reference is made
herein to "THE BUSINESS OF" an entity, such reference shall be deemed to include
the business of all direct and indirect subsidiaries of such entity. Reference
to the subsidiaries of an entity shall be deemed to include all direct and
indirect subsidiaries of such entity.

         (b) For purposes of this Agreement, the term "KNOWLEDGE" means with
respect to a party hereto, with respect to any matter in question, that any of
the officers of such party has actual knowledge of such matter, after reasonable
inquiry of such matter.

         (c) For purposes of this Agreement, the term "MATERIAL ADVERSE EFFECT"
when used in connection with an entity means any change, event, violation,
inaccuracy, circumstance or effect that is or is reasonably likely to be
materially adverse to the business, assets (including intangible assets),
capitalization, financial condition, operations or results of operations of such
entity taken as a whole with its subsidiaries, except to the extent that any
such change, event, violation, inaccuracy, circumstance or effect directly and
primarily results from (i) changes in general economic conditions or changes
affecting the industry generally in which such entity operates (provided that
such changes do not affect such entity in a substantially disproportionate
manner) or (ii) changes in the trading prices for such entity's capital stock.

         (d) For purposes of this Agreement, the term "PERSON" shall mean any
individual, corporation (including any non-profit corporation), general
partnership, limited partnership, limited liability partnership, joint venture,
estate, trust, company (including any limited liability company or joint stock
company), firm or other enterprise, association, organization, entity or
Governmental Entity.

         (e) For purposes of this Agreement, "SUBSIDIARY" of a specified entity
will be any corporation, partnership, limited liability company, joint venture
or other legal entity of which the specified entity (either alone or through or
together with any other subsidiary) owns, directly or indirectly, 50% or more of
the stock or other equity or partnership interests the holders of which are
generally entitled to vote for the election of the Board of Directors or other
governing body of such corporation or other legal entity. For the avoidance of
doubt, Healthvision is not a subsidiary of Company.

         (f) Disclosure made with regard to a representation or warranty of a
party in a Part of either the Company Disclosure Letter or Parent Disclosure
Letter shall also be deemed to qualify other representations and warranties of
the party making such disclosure if it is readily apparent from the language
contained in such disclosure that such disclosure is applicable to such other
representation or warranty.

     8.4 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

     8.5 Entire Agreement; Third Party Beneficiaries. This Agreement, its
Exhibits and the documents and instruments and other agreements among the
parties hereto as contemplated

                                      -66-
<PAGE>   71

by or referred to herein, including the Company Disclosure Letter and the Parent
Disclosure Letter (a) constitute the entire agreement among the parties with
respect to the subject matter hereof and supersede all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof, it being understood that the Confidentiality Agreement
shall continue in full force and effect until the Closing and shall survive any
termination of this Agreement; and (b) are not intended to confer upon any other
person any rights or remedies hereunder, except as specifically provided in
Section 5.11.

     8.6 Severability. In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction
to be illegal, void or unenforceable, the remainder of this Agreement will
continue in full force and effect and the application of such provision to other
persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the extent possible, the economic, business and other
purposes of such void or unenforceable provision.

     8.7 Other Remedies; Specific Performance. Except as otherwise provided
herein, any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy. The parties hereto
agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to seek an injunction or injunctions to prevent

the matters referred to in Section 1.2, or (ii) to take action by written
consent of the stockholders of Company with respect to the matters referred to

the period from the date of this Agreement through the earlier of termination of
this Agreement pursuant to Section 3 below or the record date for the meeting at
which stockholders of Company are asked to vote upon approval of the Merger
Agreement and the Merger.

              (c) Transfer. Stockholder shall be deemed to have effected a
"TRANSFER" of a security if Stockholder directly or indirectly: (i) sells,
pledges, encumbers, transfers or disposes of, or grants an option with respect
to, such security or any interest in such security; or (ii) enters into an
agreement or commitment providing for the sale, pledge, encumbrance, transfer or
disposition of, or grant of an option with respect to, such security or any
interest therein.

     1.2 Agreement to Vote Shares. Stockholder hereby covenants and agrees that,
during the period commencing on the date hereof and continuing until the first
to occur of (i) such date and time as the Merger shall become effective in
accordance with the terms and provisions of the Merger Agreement (THE "EFFECTIVE
TIME") and (ii) termination of this Agreement in accordance with its terms, at
any meeting (whether annual or special and whether or not an adjourned or
postponed meeting) of the stockholders of Company, however called, or in
connection with any written consent of the stockholders of Company, Stockholder
will appear at the meeting or otherwise cause the Shares to be counted as
present thereat for purposes of establishing a quorum and vote or consent (or
cause to be voted or consented) the Shares:

          (1) in favor of the approval and adoption of the Merger Agreement in
     the form entered into on the date hereof and the approval of the Merger and
     the other actions contemplated by the Merger Agreement and any actions
     required in furtherance thereof;

          (2) against approval of any proposal made in opposition to or in
     competition with the consummation of the Merger, including, without
     limitation, any Acquisition Proposal or Superior Offer (each as defined in
     the Merger Agreement) or any action or agreement that would result in a
     breach in any respect of any covenant, representation or warranty or any
     other obligation or agreement of Company under the Merger Agreement or of
     Stockholder under this Agreement.

     Stockholder further agrees not to enter into any agreement or understanding
with any person the effect of which would be inconsistent with or violative of

<PAGE>   76


         1.3 Transfer and Other Restrictions. (a) Prior to the termination of
this Agreement, Stockholder agrees not to, directly or indirectly:

               (i) except pursuant to the terms of the Merger Agreement, offer
          for sale, Transfer or otherwise dispose of, or enter into any
          contract, option or other arrangement or understanding with respect to
          or consent to the offer for sale, Transfer or other disposition of any
          or all of the Subject Securities or any interest therein except as
          provided in Section 1.2 hereof;

               (ii) grant any proxy, power of attorney, deposit any of the

          agreement or arrangement with respect to the Subject Securities except
          as provided in this Agreement; or

               (iii) take any other action that would make any representation or
          warranty of Stockholder contained herein untrue or incorrect or have
          the effect of preventing or disabling Stockholder from performing its
          obligations under this Agreement.

         (b) To the extent Stockholder is, as of the date hereof, party to a
contract or agreement that requires Stockholder to Transfer Subject Securities
to another person or entity (excluding a contract or agreement pledging Subject
Securities to Company), Stockholder will not effect any such Transfer unless and
until the transferee agrees to be bound by and executes an agreement in the form
of this Agreement with respect to the Subject Securities to be Transferred.
Nothing herein shall prohibit Stockholder from exercising (in accordance with
the terms of the option or warrant, as applicable) any option or warrant
Stockholder may hold; provided that the securities acquired upon such exercise
shall be deemed Subject Securities and Shares hereunder.

         1.4 Irrevocable Proxy. Concurrently with the execution of this

hereto as Exhibit I (the "PROXY"), which shall be irrevocable to the extent set
forth therein, with respect to the Shares.

         (a) Stockholder is the record and beneficial owner of, or Stockholder
exercises voting power over, the shares of Company capital stock indicated on
the final page of this Agreement, which, on and as of the date hereof, are free
and clear of any Encumbrances that would adversely affect the ability of
Stockholder to carry out the terms of this Agreement. The number of Shares set
forth on the signature pages hereto are the only Shares beneficially owned by
such Stockholder and, except as set forth on such signature pages, the
Stockholder holds no options to purchase or rights to subscribe for or otherwise
acquire any securities of the Company and has no other interest in or voting
rights with respect to any securities of the Company.

the transactions contemplated by this Agreement have been duly authorized by all
necessary action (including any consultation, approval or other action by or
with any other person). This Agreement has been duly executed and delivered by
such Stockholder and constitutes a valid and binding obligation of such
Stockholder, enforceable against such Stockholder in accordance with its terms.
The execution and delivery of this Agreement does not, and the consummation of
the transactions contemplated by this Agreement and compliance with the
provisions of this Agreement will not, conflict with, or result in any violation
of, or default (with or without notice or lapse of time, or both) under, or give
rise to a right of termination, cancellation or acceleration of any obligation
which would result in the creation of any Encumbrance upon any of the Shares
owned by such Stockholder under, any provision of Stockholder's charter
documents (if applicable), applicable law or regulation or of any agreement,
judgment, injunction, order, decree, or other instrument binding on such
Stockholder or any Shares owned by such Stockholder. No consent, approval, order
or authorization of, or registration, declaration or filing with or exemption by
any Governmental Entity is required by or with respect to such Stockholder in
connection with the execution and delivery of this Agreement by such Stockholder
or the consummation by such Stockholder of the transactions contemplated by this
Agreement, except for applicable requirements, if any, of Sections 13 and 16 of
the Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder. If this Agreement is being executed in a representative or fiduciary
capacity, the person signing this Agreement has full power and authority to
enter into and perform such Agreement.

materially adverse to Stockholder without Stockholder's consent.

this Agreement is held by a court of competent jurisdiction to be invalid, void

          the Eclipsys Merger and in the Healthvision Merger, and in favor of
          the issuance of shares of Parent Common Stock and Warrants to purchase

          Warrant Agreements, and the other actions contemplated by the Eclipsys
          Merger Agreement, Healthvision Merger Agreement and Stock and Warrant
          Agreements and any actions required in furtherance thereof; and

               (2) against approval of any action or agreement that would result

          or any other obligation or agreement of Parent under the Eclipsys
          Merger Agreement, Healthvision Merger Agreement or Stock and Warrant
          Agreements, or of Stockholder under this Agreement.

               (iii) take any other action that would make any representation or
          warranty of Stockholder contained herein untrue or incorrect or have
          the effect of preventing or disabling Stockholder from performing its
          obligations under this Agreement.

         (b) To the extent Stockholder is, as of the date hereof, party to a
contract or agreement that requires Stockholder to Transfer Subject Securities
to another person or entity (excluding a contract or agreement pledging Subject
Securities to Parent), Stockholder will not effect any such Transfer unless and
until the transferee agrees to be bound by and executes an agreement in the form
of this Agreement with respect to the Subject Securities to be Transferred.
Nothing herein shall prohibit Stockholder from exercising (in accordance with
the terms of the option or warrant, as applicable) any option or warrant
Stockholder may hold; provided that the securities acquired upon such exercise

exercises voting power over, the shares of Parent capital stock indicated on the
final page of this Agreement, which, on and as of the date hereof, are free and
clear of any Encumbrances that would adversely affect the ability of Stockholder

consultation, approval or other action by or with any other person). This
Agreement has been duly executed and delivered by such Stockholder and
constitutes a valid and binding obligation of such Stockholder, enforceable
against such Stockholder in accordance with its terms. The execution and
delivery of this Agreement does not, and the consummation of the transactions
contemplated by this Agreement and compliance with the provisions of this
Agreement will not, conflict with, or result in any violation of, or default
(with or without notice or lapse of time, or both) under, or give rise to a
right of termination, cancellation or acceleration of any obligation which would
result in the creation of any Encumbrance upon any of the Shares owned by such
Stockholder under, any provision of Stockholder's charter documents (if
applicable), applicable law or regulation or of any agreement, judgment,
injunction, order, decree, or other instrument binding on such Stockholder or
any Shares owned by such

                                       4

delivery of this Agreement by such Stockholder or the consummation by such
Stockholder of the transactions contemplated by this Agreement, except for
applicable requirements, if any, of Sections 13 and 16 of the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder. If
this Agreement is being executed in a representative or fiduciary capacity, the
person signing this Agreement has full power and authority to enter into and
perform such Agreement.

     3. TERMINATION

     This Agreement shall terminate and shall have no further force or effect as
of the first to occur of (i) the Effective Time and (ii) such date and time as
the Eclipsys Merger Agreement, Healthvision Merger Agreement or the Stock and
Warrant Agreements shall have been validly terminated pursuant to the terms
thereof. Notwithstanding any other provision hereof, this Agreement shall
terminate in the event that either the Eclipsys Merger Agreement or the
Healthvision Merger Agreement is modified in a manner that is materially adverse
to Stockholder without Stockholder's consent.

     4. MISCELLANEOUS

         4.1 Severability. If any term, provision, covenant or restriction of

in no way be affected, impaired or invalidated.

provisions hereof shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns, but, except as
otherwise specifically provided herein, neither this Agreement nor any of the

of the parties without prior written consent of the other. Any purported
assignment in violation of this Section shall be void.

         4.3 Amendments and Modification. This Agreement may not be modified,
amended, altered or supplemented except upon the execution and delivery of a
written agreement executed by the parties hereto.

                          AGREEMENT AND PLAN OF MERGER


     This AGREEMENT AND PLAN OF MERGER (this "AGREEMENT") is made and entered
into as of March 30, 2000, by and between Neoforma.com, Inc., a Delaware
corporation ("NEOFORMA"), and HEALTHvision, Inc., a Delaware corporation
("HEALTHVISION").

                                    RECITALS

     A. Immediately prior to the closing of the transaction contemplated hereby,
Neoforma will acquire Eclipsys Corporation, a Delaware corporation ("ECLIPSYS"),
by virtue of a reverse triangular merger ("ECLIPSYS MERGER"), as a result of
which Eclipsys will become a wholly owned subsidiary of Neoforma, pursuant to an
Agreement and Plan of Merger by and among Eclipsys, Neoforma and a subsidiary of
Neoforma ("ECLIPSYS AGREEMENT"). Eclipsys owns, on an as converted basis,
approximately a 34% outstanding equity interest in Healthvision as of the date
of this Agreement ("ECLIPSYS' EQUITY INTEREST IN HEALTHVISION"). Concurrently
with the execution of this Agreement, Neoforma is entering into an Outsourcing
and Operating Agreement (the "NOVATION OPERATING AGREEMENT") among Neoforma,
Novation, LLC, a Delaware limited liability company ("NOVATION"), VHA Inc., a
Delaware corporation ("VHA"), University HealthSystem Consortium, an Illinois
corporation ("UHC"), and Healthcare Purchasing Partners International, LLC, a
Delaware limited liability company ("HPPI"), and Common Stock and Warrant
Agreements between Neoforma and VHA, and Neoforma and UHC, respectively (the
"STOCK AND WARRANT AGREEMENTS" and, together with the Novation Operating
Agreement, the "NOVATION DOCUMENTS," and the Novation Documents together with
the Eclipsys Merger Agreement, the "RELATED AGREEMENTS"), copies of each of
which and all related documents are attached to the Neoforma Disclosure Letter
(as defined in the introduction to Article III). The transactions contemplated
by this Agreement and the Related Agreements are collectively referred to herein
as the "TRANSACTION."

     B. The respective Boards of Directors of Neoforma and Healthvision have
approved this Agreement and declared advisable the merger of Healthvision with
and into Eclipsys (the "MERGER") upon the terms and subject to the conditions of
this Agreement and in accordance with the General Corporation Law of the State
of Delaware ("DELAWARE LAW"), and the respective Boards of Directors of
Neoforma, Healthvision and Eclipsys have approved an agreement of merger to be
filed with the Delaware Secretary of State (the "AGREEMENT OF MERGER") in the
form of Exhibit A.

     C. For United States federal income tax purposes, the Merger is intended to
qualify as a "reorganization" pursuant to the provisions of Section 368 of the
Internal Revenue Code of 1986, as amended (the "CODE"), by virtue of the
provisions of Section 368(a)(2)(D) of the Code relating to "forward triangular"
mergers. For accounting purposes, the Merger is intended to be accounted for as
a purchase under United States generally accepted accounting principles
("GAAP").

     D. Concurrently with the execution of this Agreement, and as a condition
and inducement to Neoforma's willingness to enter into this Agreement, certain
stockholders of
<PAGE>   6

Healthvision are entering into Voting Agreements with Neoforma in the form of
Exhibit B (the "HEALTHVISION VOTING AGREEMENTS").

     E. Concurrently with the execution of this Agreement, and as a condition
and inducement to Healthvision's willingness to enter into this Agreement,
certain stockholders of Neoforma are entering into Voting Agreements with
Healthvision and Eclipsys in the form of Exhibit C (the "NEOFORMA VOTING
AGREEMENTS").

     In consideration of the foregoing and the representations, warranties,
covenants and agreements set forth in this Agreement, the parties agree as
follows:




                                    ARTICLE I
                                   THE MERGER

     1.1 The Merger. Upon the terms and subject to the conditions of this
Agreement and the applicable provisions of Delaware Law, at the Effective Time,
Healthvision shall be merged with and into Eclipsys, the separate corporate
existence of Healthvision shall cease, and Eclipsys shall continue as the
surviving corporation of the Merger (the "SURVIVING CORPORATION").

     1.2 Effective Time; Closing. Subject to the provisions of this Agreement,
the parties hereto shall cause the Merger to be consummated by filing the
Agreement of Merger with the Secretary of State of the State of Delaware in
accordance with the relevant provisions of Delaware Law (the time of such filing
(or such later time as may be agreed in writing by Healthvision and Neoforma and
specified in the Agreement of Merger) being the "EFFECTIVE TIME") as soon as
practicable immediately following the consummation of the Eclipsys Merger on or
after the Closing Date. The closing of the Merger (the "CLOSING") shall take
place at the offices of Fenwick & West LLP, Two Palo Alto Square, Palo Alto,
California, at a time and date to be specified by the parties, which shall be no
later than the second business day after the satisfaction or waiver of the
conditions set forth in Article VI, or at such other time, date and location as
the parties hereto agree in writing (the "CLOSING DATE").

     1.3 Effect of the Merger. At the Effective Time, the effect of the Merger
shall be as provided in this Agreement and the applicable provisions of Delaware
Law. Without limiting the generality of the foregoing, at the Effective Time,
all the property, rights, privileges, powers and franchises of Healthvision and
Eclipsys shall vest in the Surviving Corporation, and all debts, liabilities and
duties of Healthvision and Eclipsys shall become the debts, liabilities and
duties of the Surviving Corporation and Eclipsys' Equity Interest in
Healthvision shall be cancelled without consideration.

     1.4 Certificate of Incorporation; Bylaws.

         (a) At the Effective Time, the Certificate of Incorporation of
Eclipsys, as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the

                                      -2-
<PAGE>   7

Surviving Corporation until thereafter amended as provided by law and such
Certificate of Incorporation of the Surviving Corporation.

         (b) At the Effective Time, the Bylaws of Eclipsys, as in effect
immediately prior to the Effective Time, shall be the Bylaws of the Surviving
Corporation until thereafter amended.

     1.5 Directors and Officers. The initial directors of the Surviving
Corporation shall be the directors of Eclipsys immediately prior to the
Effective Time, until their respective successors are duly elected or appointed
and qualified. The initial officers of the Surviving Corporation shall be the
officers of Eclipsys immediately prior to the Effective Time, until their
respective successors are duly appointed.

     1.6 Effect on Capital Stock. Subject to the terms and conditions of this
Agreement, at the Effective Time, capital stock and rights to purchase capital
stock will, by virtue of the Merger, be treated as follows:


              1.6.1 Conversion of Healthvision Preferred Stock. At the Effective
Time, the shares of each outstanding series of Preferred Stock of Healthvision,
$0.01 par value per share ("HEALTHVISION PREFERRED STOCK"), shall be converted
into Neoforma Common Stock, $0.001 par value ("NEOFORMA COMMON STOCK"), in the
manner provided for in this Agreement. Accordingly, at the Effective Time each
share of Healthvision Preferred Stock issued and outstanding immediately prior
thereto (other than Dissenting Shares (as defined below)) shall be canceled and
converted as follows:

                   (a) each share of Healthvision's Series A Convertible
Participating Preferred Stock ("SERIES A STOCK") shall automatically be
converted in the Merger into (i) .3041825 of a share (such fraction representing
$10 divided by $32-7/8ths) of Neoforma Common Stock plus (ii) four shares of
Common Stock of Healthvision, $0.01 par value per share ("HEALTHVISION COMMON
STOCK") (subject to further conversion as provided in Section 1.6.2 below);

                   (b) each outstanding share of Healthvision's Series B
Convertible Preferred Stock ("SERIES B STOCK"), if any, will be converted in the
Merger into four shares of Healthvision Common Stock (subject to further
conversion as provided in Section 1.6.2 below).

              1.6.2 Conversion of Shares of Healthvision Common Stock. Each
share of Healthvision Common Stock (including Healthvision Common Stock issued
or issuable as a result of the automatic conversion of outstanding shares of
Series A Stock in part into Healthvision Common Stock at the Effective Time as
described in Section 1.6.1(a)(ii) above and the conversion of any outstanding
shares of Series B Stock into Healthvision Common Stock at the Effective Time as
described in Section 1.6.1(b) above) that is issued and outstanding immediately
prior to the Effective Time (in each case, other than Dissenting Shares) will,
by virtue of the Merger and at the Effective Time, and without further action on
the part of any holder thereof, be converted into 0.444 (the "EXCHANGE RATIO")
fully paid and nonassessable shares of Neoforma Common Stock. No fraction of a
share of Neoforma Common Stock will be

                                      -3-
<PAGE>   8

issued by virtue of the Merger, but in lieu thereof, a cash payment shall be
made pursuant to Section 1.7(e).

              1.6.3 Assumptions of Options. At the Effective Time, Neoforma will
assume all options to purchase Healthvision common stock outstanding at the
Effective Time (the "HEALTHVISION OPTIONS") pursuant to Healthvision's 1999
Stock Incentive Plan ("1999 PLAN"). At the Effective Time, each Healthvision
Option shall be converted into an option (a "NEOFORMA OPTION") to purchase that
number of shares of Neoforma Common Stock that is equal to the number of shares
of Healthvision Common Stock that could be purchased pursuant to such
Healthvision Option immediately prior to the Effective Time multiplied by the
Exchange Ratio, with fractional shares being rounded down to the nearest whole
share. The exercise price per share of Neoforma Common Stock purchasable under
each Healthvision Option assumed and converted into a Neoforma Option shall be
equal to the exercise price per share of Healthvision Common Stock under such
Healthvision Option immediately prior to the Effective Time divided by the
Exchange Ratio, rounded up to the nearest cent. No cash will be paid in lieu of
fractional shares which are rounded down pursuant to this Section. The term,
exercisability, vesting schedule, status as an "incentive stock option" under
Section 422 of the Code, if applicable, and all other terms of Healthvision
Options will otherwise be unchanged. Continuous employment with Healthvision
will be credited to an optionee for purposes of determining the number of shares
subject to exercise after the Effective Time. Neoforma agrees to file with the
Securities and Exchange Commission ("SEC") a registration statement on Form S-8
for the shares of Neoforma Common Stock issuable with respect to assumed
Healthvision Options as soon as is reasonably practicable after the Effective
Time, and maintain the effectiveness of such registration statement thereafter
for so long as any of such options or other rights remain outstanding, and will
reserve a sufficient number of shares of Neoforma Common Stock for issuance upon
exercise thereof.

              1.6.4 Assumptions of Healthvision Warrants. At the Effective Time,
Neoforma will assume all outstanding warrants to purchase capital stock of
Healthvision ("HEALTHVISION WARRANTS"). Each Healthvision Warrant shall be
automatically exchanged for a five-year warrant in substantially the form of
Exhibit 1.6.4 (a "NEOFORMA WARRANT"), to purchase that number of shares of
Neoforma Common Stock that is equal to the number of shares of Healthvision
Common Stock (assuming Series B Stock has been previously issued and
automatically converted into Healthvision Common Stock) that could be purchased
pursuant to such Healthvision Warrant immediately prior to the Effective Time
multiplied by the Exchange Ratio, with fractional shares being rounded down to
the nearest whole share. The exercise price per share for each such substituted
Neoforma Warrant shall equal $3.75 divided by the Exchange Ratio, rounded up to
the nearest cent. No cash will be paid in lieu of fractional shares which are
rounded down pursuant to this Section.

              1.6.5 Cancellation of Healthvision Owned and Eclipsys Owned Stock.
Each share of Healthvision capital stock held by Healthvision or owned by
Eclipsys or any direct or indirect wholly owned subsidiary of Eclipsys or
Healthvision immediately prior to the Effective Time shall be canceled and
extinguished without any conversion thereof.


                                      -4-
<PAGE>   9


              1.6.6 Capital Stock of Eclipsys. Each share of common stock, par
value $0.01 per share, of Eclipsys (the "ECLIPSYS COMMON STOCK"), issued and
outstanding after the Eclipsys Merger and immediately prior to the Effective
Time of the Merger shall be converted into one validly issued, fully paid and
nonassessable share of common stock, $0.01 par value per share, of the Surviving
Corporation. Following the Effective Time, each certificate evidencing ownership
of shares of Eclipsys common stock shall evidence ownership of such shares of
common stock of the Surviving Corporation.

              1.6.7 Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect appropriately the effect of any stock split, reverse stock
split, stock dividend (including any dividend or distribution of securities
convertible into Neoforma Common Stock or Healthvision Common Stock),
reorganization, recapitalization, reclassification or other like change with
respect to Neoforma Common Stock or Healthvision Common Stock occurring on or
after the date hereof and prior to the Effective Time.

     1.7 Exchange of Certificates.

         (a) Exchange Agent. Neoforma shall select an institution reasonably
acceptable to Healthvision to act as the exchange agent (the "EXCHANGE AGENT")
in the Merger.

         (b) Exchange Fund. Promptly after the Effective Time, Neoforma shall
make available to the Exchange Agent for exchange in accordance with this
Article I, the shares of Neoforma Common Stock (such shares of Neoforma Common
Stock, together with cash in lieu of fractional shares and any dividends or
distributions with respect thereto, are hereinafter referred to as the "EXCHANGE
FUND") issuable pursuant to Section 1.6 in exchange for outstanding shares of
Healthvision Common Stock and/or Healthvision Preferred Stock (collectively,
"HEALTHVISION STOCK").

         (c) Exchange Procedures. Promptly after the Effective Time, Neoforma
shall instruct the Exchange Agent to mail to each holder of record of a
certificate or certificates ("CERTIFICATES") which immediately prior to the
Effective Time represented outstanding shares of Healthvision Stock whose shares
were converted into shares of Neoforma Common Stock pursuant to Section 1.6, (i)
a letter of transmittal in customary form (that shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Exchange Agent and shall
contain such other provisions as Neoforma may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Neoforma Common Stock. Upon surrender of
Certificates for cancellation to the Exchange Agent together with such letter of
transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holders of such Certificates shall be entitled to
receive in exchange therefor certificates representing the number of whole
shares of Neoforma Common Stock into which their shares of Healthvision Stock
were converted at the Effective Time, payment in lieu of fractional shares that
such holders have the right to receive pursuant to Section 1.7(e) and any
dividends or distributions payable pursuant to Section 1.7(d), and the
Certificates so surrendered shall forthwith be canceled. Until so surrendered,
outstanding Certificates will be deemed from and after the Effective Time, for
all corporate purposes, to evidence only the ownership of the

                                      -5-
<PAGE>   10

number of full shares of Neoforma Common Stock into which such shares of
Healthvision Stock shall have been so converted and the right to receive an
amount in cash in lieu of the issuance of any fractional shares in accordance
with Section 1.7(e) and any dividends or distributions payable pursuant to
Section 1.7(d). No interest will be paid or accrued on any cash in lieu of
fractional shares of Neoforma Stock or on any unpaid dividends or distributions
payable to holders of Certificates. In the event of a transfer of ownership of
shares of Healthvision Stock which is not registered in the transfer records of
Healthvision, a certificate representing the proper number of shares of Neoforma
Common Stock may be issued to a transferee if the Certificate representing such
shares of Healthvision Stock is presented to the Exchange Agent, accompanied by
all documents required to evidence and effect such transfer and by evidence that
any applicable stock transfer taxes have been paid.

         (d) Distributions With Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the date of this Agreement with
respect to Neoforma Stock with a record date after the Effective Time will be
paid to the holders of any unsurrendered Certificates with respect to the shares
of Neoforma Common Stock represented thereby until the holders of record of such
Certificates shall surrender such Certificates. Subject to applicable law,
following surrender of any such Certificates, the Exchange Agent shall deliver
to the holders of certificates representing whole shares of Neoforma Common
Stock issued in exchange therefor, without interest, (i) promptly, the amount of
any cash payable with respect to a fractional share of Neoforma Common Stock to
which such holder is entitled pursuant to Section 1.7(e) and the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of Neoforma Common Stock, and
(ii) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time but prior to surrender
and a payment date occurring after surrender, payable with respect to such whole
shares of Neoforma Common Stock.

         (e) Fractional Shares.

              (i) As promptly as practicable following the Effective Time, the
Exchange Agent shall determine the excess of (A) the number of full shares of
Neoforma Common Stock delivered to the Exchange Agent pursuant to Section
1.7(b), over (B) the aggregate number of full shares of Neoforma Common Stock to
be distributed to holders of Healthvision Stock pursuant to Section 1.7(c) (such
excess, the "EXCESS SHARES"). Following the Effective Time, the Exchange Agent,
as agent for the holders of Healthvision Stock, shall sell the Excess Shares at
then prevailing prices on the Nasdaq Stock Market in the manner set forth in
paragraph (ii) of this Section 1.7(e).

              (ii) The sale of the Excess Shares by the Exchange Agent shall be
executed on the Nasdaq Stock Market and shall be executed in round lots to the
extent practicable. The Exchange Agent shall use all commercially reasonable
efforts to complete the sale of the Excess Shares as promptly following the
Effective Time as, in the Exchange Agent's reasonable judgment, is practicable
consistent with obtaining the best execution of such sales in light of
prevailing market conditions. Until the net proceeds of such sales have been
distributed to the holders of Healthvision Stock, the Exchange Agent will hold
such proceeds in trust for the holders of Healthvision Stock. The Exchange Agent
will determine the portion of such net

                                      -6-
<PAGE>   11

proceeds to which each holder of Healthvision Stock shall be entitled, if any,
by multiplying the amount of the aggregate net proceeds by a fraction the
numerator of which is the amount of the fractional share interest to which such
holder of Healthvision Stock is entitled (after taking into account all shares
of Neoforma Common Stock to be issued to such holder) and the denominator of
which is the aggregate amount of fractional share interests to which all holders
of Healthvision Stock are entitled. As soon as practicable after the
determination of the amount of cash, if any, to be paid to holders of
Healthvision Stock with respect to fractional share interests, the Exchange
Agent shall promptly pay such amounts to such holders of Healthvision Stock in
accordance with the terms of Section 1.7(c).

              (iii) Notwithstanding the provisions of paragraphs (i) and (ii) of
this Section 1.7(e), Neoforma may decide, at its option, exercised prior to the
Effective Time, in lieu of the issuance and sale of Excess Shares and the making
of the payments contemplated in such paragraphs, that Neoforma shall pay to the
Exchange Agent an amount sufficient for the Exchange Agent to pay each holder of
Healthvision Common Stock the amount such holder would have received pursuant to
Section 1.7(e)(ii) assuming that the sales of Neoforma Common Stock were made at
a price equal to the average of the closing prices of the Neoforma Common Stock
on the Nasdaq Stock Market for the ten consecutive trading days immediately
following the Effective Time and, in such case, all references herein to the
cash proceeds of the sale of the Excess Shares and similar references shall be
deemed to mean and refer to the payments calculated as set forth in this
paragraph (iii). In such event, Excess Shares shall not be issued or otherwise
transferred to the Exchange Agent pursuant to Sections 1.7(b) or (e).

         (f) Required Withholding. Each of the Exchange Agent, Neoforma and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Healthvision Common Stock such amounts as may be
required to be deducted or withheld therefrom under the Code or under any
provision of state, local or foreign tax law or under any other applicable Legal
Requirement (as defined in Section 2.2(c)). To the extent such amounts are so
deducted or withheld, such amounts shall be treated for all purposes under this
Agreement as having been paid to the person to whom such amounts would otherwise
have been paid.

         (g) Lost, Stolen or Destroyed Certificates. In the event that any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, certificates
representing the shares of Neoforma Common Stock into which the shares of
Healthvision Stock represented by such Certificates were converted pursuant to
Section 1.6, cash for fractional shares, if any, as may be required pursuant to
Section 1.7(e) and any dividends or distributions payable pursuant to Section
1.7(d); provided, however, that Neoforma may, in its discretion and as a
condition precedent to the issuance of such certificates representing shares of
Neoforma Common Stock, cash and other distributions, require the owner of such
lost, stolen or destroyed Certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made against
Neoforma, the Surviving Corporation or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.


                                      -7-
<PAGE>   12


         (h) No Liability. Notwithstanding anything to the contrary in this
Section 1.7, neither the Exchange Agent, Neoforma, the Surviving Corporation nor
any party hereto shall be liable to a holder of shares of Neoforma Common Stock
or Healthvision Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

         (i) Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the holders of Healthvision Stock for six months
after the Effective Time shall be delivered to Neoforma, upon demand, and any
holders of Healthvision Stock who have not theretofore complied with the
provisions of this Section 1.7 shall thereafter look only to Neoforma for the
shares of Neoforma Common Stock, any cash in lieu of fractional shares of
Neoforma Common Stock to which they are entitled pursuant to Section 1.7(e) and
any dividends or other distributions with respect to Neoforma Common Stock to
which they are entitled pursuant to Section 1.7(d), in each case, without any
interest thereon.

     1.8 No Further Ownership Rights in Healthvision Stock. All shares of
Neoforma Common Stock issued in accordance with the terms hereof (including any
cash paid in respect thereof pursuant to Sections 1.7(d) and (e)) shall be
deemed to have been issued in full satisfaction of all rights pertaining to such
shares of Healthvision Stock, and there shall be no further registration of
transfers on the records of the Surviving Corporation of shares of Healthvision
Stock that were outstanding immediately prior to the Effective Time. If after
the Effective Time Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article I.

Healthvision upon any termination of the stockholders' employment, directorship
or other relationship with Healthvision (and/or any affiliate of Healthvision)
under the terms of any restricted stock purchase agreement or other agreement
with Healthvision that does not by its terms provide that such repurchase
option, risk of forfeiture or other condition lapses upon consummation of the
Merger, then the shares of Neoforma Common Stock issued upon the conversion of
such shares of Healthvision Common Stock in the Merger will continue to be
unvested and subject to the same repurchase options, risks of forfeiture or
other conditions following the Effective Time, and the certificates representing
such shares of Neoforma Common Stock may accordingly be marked with appropriate
legends noting such repurchase options, risks of forfeiture or other conditions.
Healthvision shall take all actions that may be necessary to ensure that, from
and after the Effective Time, Neoforma is entitled to exercise any such
repurchase option or other right set forth in any such restricted stock purchase
agreement or other agreement. A listing of the holders of Healthvision

and franchises of Healthvision and Eclipsys, the officers and directors of
Healthvision and Eclipsys will take all such lawful and necessary action.
Neoforma shall cause Eclipsys to perform all of its obligations relating to this
Agreement and the transactions contemplated hereby.

antitrust laws of any foreign country; and (iv) such other consents,
authorizations, filings, approvals and registrations which if not obtained or
made would not have a Material Adverse Effect on Healthvision, Neoforma, or the
Surviving Corporation or would not have a material adverse effect on the ability

Healthvision, or any material settlement reached by Healthvision with, any party
or parties alleging the presence, disposal, release or threatened release of any

         (j) Employment Matters. Except, in each case, as would not,

than routine payments to be made in the normal course of business and consistent
with past practice). There are no pending, or, to Neoforma's knowledge,
threatened material claims or actions against Neoforma under any worker's
compensation policy or long-term disability policy. To Neoforma's knowledge, no
Neoforma Employee of Neoforma has violated in any material manner any employment
contract, nondisclosure agreement or noncompetition agreement by which such
Neoforma Employee is bound due to such Neoforma Employee being employed by
Neoforma and disclosing to Neoforma or using trade secrets or proprietary
information of any other person or entity.

         (k) Labor. No work stoppage or labor strike against Neoforma is
pending, threatened or reasonably anticipated. Neoforma does not know of any
activities or proceedings of any labor union to organize any Neoforma Employees.
There are no actions, suits, claims, labor disputes or grievances pending, or,
to the knowledge of Neoforma, threatened or reasonably anticipated relating to
any labor, safety or discrimination matters involving any Neoforma Employee,
including charges of unfair labor practices or discrimination complaints, which,
if adversely determined, would, individually or in the aggregate, result in any
material liability to Neoforma. Neither Neoforma nor any of its subsidiaries has
engaged in any unfair labor practices within the meaning of the National Labor
Relations Act. Neoforma is not presently, nor has it been in the past, a party
to, or bound by, any collective bargaining agreement or union contract with
respect to Neoforma Employees and no collective bargaining agreement is being
negotiated by Neoforma.

         (l) International Employee Plan. Each International 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 Employee
Plan. Furthermore, no International Employee Plan has unfunded liabilities, that
as of the Effective Time, will not be offset by insurance or fully accrued.
Except as required by law, no condition exists that would prevent Neoforma or
Neoforma from terminating or amending any International Employee Plan at any
time for any reason.

     3.13 Environmental Matters. During the period that Neoforma 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

                                      -39-
<PAGE>   44

properties or facilities that would have a Material Adverse Effect on Neoforma.
Neoforma 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 Neoforma 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 Neoforma. None of
the properties or facilities currently leased or owned by Neoforma or any of its
subsidiaries or any properties or facilities previously leased or owned by
Neoforma 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 Neoforma. During Neoforma's occupancy of
any properties or facilities owned or leased at any time by Neoforma, neither
Neoforma, nor to Neoforma'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 Neoforma. During the time that Neoforma 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 Neoforma
or any of its subsidiaries, there has been no material litigation, proceeding or
administrative action brought or threatened against Neoforma or any of its
subsidiaries, or any material settlement reached by Neoforma 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.

exclusive rights;

insurance and bonds of the type and in amounts customarily carried by persons
conducting business or owning assets similar to those of the Neoforma and its
subsidiaries. There is no material claim pending under any of such policies or
bonds as to which coverage has been questioned, denied or disputed by the
underwriters of such policies or bonds. All premiums due and payable under all
such policies have been paid and the Neoforma and its subsidiaries are otherwise
in compliance in all material respects with the terms of such policies and
bonds.

to the Indemnified Parties as those contained in the Certificate of
Incorporation and Bylaws of Healthvision as in effect on the date hereof, which
provisions will not be amended, repealed or otherwise modified for a period of
six years from the Effective Time in any manner that would adversely affect the
rights thereunder of individuals who, immediately prior to the Effective Time,
were directors or officers of Healthvision, unless such modification is required
by law.

         (b) For a period of six years after the Effective Time, Neoforma will
cause the Surviving Corporation to use its commercially reasonable efforts to
maintain in effect, if available, directors' and officers' liability insurance
covering those persons who are currently covered by Healthvision's directors'
and officers' liability insurance policy on terms comparable to those applicable
to the current directors and officers of Healthvision; provided, however, that

                                      -54-
<PAGE>   59


in no event will Neoforma or the Surviving Corporation be required to expend in
excess of 200% of the annual premium currently paid by Healthvision for such
coverage (or such coverage as is available for such 200% of such annual
premium).

         (c) This Section 5.9 shall survive the consummation of the Merger, is
intended to benefit Healthvision, the Surviving Corporation and each Indemnified
Party, shall be binding on all successors and assigns of the Surviving
Corporation and Neoforma, and shall be enforceable by the Indemnified Parties.

     5.10 Neoforma Board of Directors; Executive Officers. The Board of
Directors of Neoforma will take all actions reasonably necessary such that as
soon as practicable following the Effective Time, (i) the size of Neoforma's
Board of Directors shall be increased to nine, and the following persons shall
be appointed to Neoforma's Board of Directors to fill the five vacancies in the
following classes: three persons nominated by Eclipsys, one of whom shall be
Harvey J. Wilson, who shall be appointed to Class III, one of whom shall be
affiliated with General Atlantic Partners, LLC, who shall be appointed to Class
I, and the other of whom shall be appointed to Class II, one person shall be
appointed by Healthvision to Class I, and one person shall be appointed by VHA
to Class I, and (ii) Harvey J. Wilson shall be elected Chairperson of the Board
of Directors of Neoforma, and Robert Zollars shall be elected Chief Executive
Officer and President of Neoforma. Under the Neoforma 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
Neoforma's annual meeting in 2000, or, if such annual meeting is held following
the Effective Time and such person so elects, following the Effective Time but
prior to such annual meeting. Class I Directors appointed following such annual
meeting shall have terms that end in 2003, subject to such directors' earlier
resignation or removal.

     5.11 Nasdaq Listing. Neoforma agrees to authorize for listing on the Nasdaq

respective reasonable efforts to cause to be delivered to Neoforma a letter of
Healthvision's and Neoforma's independent accountants, respectively, dated no
more than two business days before the date on which the Registration Statement
becomes effective (and satisfactory in form and substance to Neoforma), that is
customary in scope and substance for letters delivered by independent public
accountants in connection with registration statements similar to the
Registration Statement.

     5.13 Takeover Statutes. If any Takeover Statute is or may become applicable
to the Merger or the other transactions contemplated by this Agreement, each of
Neoforma and Healthvision 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

                                      -55-
<PAGE>   60

eliminate or minimize the effects of such Takeover Statute and any regulations
promulgated thereunder on such transactions.

     5.14 Certain Employee Benefits. As soon as practicable after the execution
of this Agreement, Neoforma and Healthvision shall confer and work together in
good faith to agree upon mutually acceptable employee benefit and compensation
arrangements which carry out the agreements set forth in the following two
sentences. Neoforma will use reasonable efforts to arrange that, as soon as
reasonably practicable after the Effective Time, Neoforma's benefit arrangements
and employee plans provide similar or comparable benefits to Healthvision's
employees generally as is provided to Neoforma's employees who are similarly
situated. Neoforma's benefit arrangements and employee plans shall give full
credit for each participant's continuous period of service with Healthvision
prior to the Effective Time for all purposes for which length of service prior
to the Effective Time is recognized under Neoforma benefit arrangements and
employee plans. At Neoforma's request, Healthvision agrees that it and its
subsidiaries shall terminate any and all Healthvision Employee Plans, if
appropriate (other than contractual agreements disclosed in the Healthvision
Disclosure Letter) immediately prior to the Effective Time.

     5.15 Discontinuance of IPO Efforts. Promptly, but in no event later than
three business days, following the date of this Agreement, Healthvision shall
discontinue its efforts to arrange for an initial public offering.

     5.16 Registration Rights. Neoforma agrees to use its reasonable efforts to
cause the holders of existing registration rights regarding Neoforma Common
Stock to surrender their existing registration rights in exchange for the
registration rights provided under the Registration Rights Agreement attached
hereto as Schedule 5.16 (the "NEW NEOFORMA REGISTRATION RIGHTS AGREEMENT").
Healthvision agrees to use its reasonable efforts to cause the holders of
existing registration rights regarding Healthvision Common Stock to surrender
their existing rights in exchange for the registration rights provided to such
party under the New Neoforma Registration Rights Agreement. Upon receipt by
Neoforma of a valid termination of all Healthvision registration rights held by
a party, Neoforma shall grant to such party the registration rights set forth in
the New Neoforma Registration Rights Agreement applicable to such party.

     5.17 Section 280G Stockholder Approval. Healthvision shall use its
reasonable best efforts to have this Agreement and the Agreement of Merger
approved by such percentage of Healthvision's outstanding voting securities as
is required by the terms of Section 280G(b)(5)(B) of the Code to avoid the
treatment of any payment or benefit under any contract, agreement or other
arrangement, including those entered into in connection with this Agreement the
Agreement of Merger, the Merger and the transactions contemplated hereby, as a
parachute payment under the federal tax laws, and to cause such stockholder
approval to have been obtained in a manner which satisfies all applicable
requirements of Section 280G(b)(5)(B) of the Code and the proposed Treasury
Regulations thereunder, including Q-7 of Section 1.280G-1 of such proposed
regulations.

     5.18 Healthvision Options. Prior to the grant of any Healthvision Options
permitted under Section 4.1(f), Healthvision agrees to amend the Healthvision
Stock Option Plan to

                                      -56-
<PAGE>   61

eliminate for all Healthvision Options granted after the date of this Agreement
the acceleration of the vesting of such Healthvision Options upon consummation
of the Merger or the other transactions contemplated hereby. Healthvision agrees
to use its commercially reasonable efforts to cause the holders of Healthvision
Options to waive any acceleration of the vesting of such Healthvision Options
upon consummation of the Merger or the other transactions contemplated hereby,
and without limiting the foregoing, Healthvision will exercise reasonable best
efforts to seek acceleration waivers from not less than (i) three of the persons
set forth on Schedule 6.3(e)(A) and (ii) nine of the eleven persons named in a
separate letter of even date herewith signed by the parties hereto.

during such 30-day period, or if Neoforma shall have materially breached this
Agreement).

                               AGREEMENT OF MERGER



     This Agreement of Merger (this "AGREEMENT") is entered into as of
_________, 2000, among Neoforma.com, Inc., a Delaware corporation ("NEOFORMA"),
Eclipsys Corporation, a Delaware corporation ("ECLIPSYS") and HEALTHvision,
Inc., a Delaware corporation ("HEALTHVISION").

                                    RECITALS

     A. Immediately prior to the closing of the transactions contemplated
hereby, Neoforma will acquire Eclipsys, in a reverse triangular merger whereby
NeoIII Acquisition Corp., a Delaware corporation and a wholly owned first-tier
subsidiary of Neoforma ("MERGER SUB") will merge with and into Eclipsys
("ECLIPSYS MERGER") with Eclipsys continuing as the surviving corporation, as a
result of which Eclipsys will become a wholly owned subsidiary of Neoforma,
pursuant to an Agreement and Plan of Merger dated as of March 30, 2000 by and
among Eclipsys, Neoforma and Merger Sub.

     B. Neoforma and Healthvision have entered into an Agreement and Plan of
Merger, dated as of March 30, 2000 (the "HEALTHVISION PLAN"), pursuant to which,
immediately after the Eclipsys Merger, Healthvision will merge in a forward
triangular merger with and into Eclipsys, with Eclipsys continuing as the
surviving corporation (the "HEALTHVISION MERGER").

     C. The respective Boards of Directors of Neoforma, Merger Sub and
Healthvision have approved this Agreement and declared it to be advisable and in
the respective interest of Neoforma, Merger Sub and Healthvision and their
stockholders, respectively, that Healthvision be merged with and into Eclipsys
upon the terms and subject to the conditions of this Agreement, the Healthvision
Plan and in accordance with the General Corporation Law of the State of Delaware
("DELAWARE LAW").

     NOW, THEREFORE, Neoforma, Eclipsys and Healthvision hereby agree as
follows:

                                    ARTICLE I
                                   THE MERGER

     1.1 The Merger. Upon the terms and subject to the conditions of this
Agreement and the applicable provisions of Delaware Law, at the Effective Time
(as defined below), Healthvision shall be merged with and into Eclipsys, the
separate corporate existence of Healthvision shall cease, and Eclipsys shall
continue as the surviving corporation of the Healthvision Merger (the "SURVIVING
CORPORATION").

     1.2 Effective Time; Closing. Subject to the provisions of this Agreement,
the parties hereto shall cause the Healthvision Merger to be consummated by
filing this Agreement with the Secretary of State of the State of Delaware in
accordance with the relevant provisions of Delaware Law (the time of such filing
(or such later time as may be agreed in writing by Healthvision and Neoforma)
being the "EFFECTIVE TIME") as soon as practicable following the


<PAGE>   73

consummation of the Eclipsys Merger on or after the Closing Date. The closing of
the Healthvision Merger shall take place at the offices of Fenwick & West LLP,
Two Palo Alto Square, Palo Alto, California, at a time and date to be specified
by the parties, which shall be no later than the second business day after the
satisfaction or waiver of the conditions set forth in the Healthvision Plan, or
at such other time, date and location as the parties hereto agree in writing
(the "CLOSING DATE").

     1.3 Effect of the Merger. At the Effective Time, the effect of the
Healthvision Merger shall be as provided in this Agreement and the applicable
provisions of Delaware Law. Without limiting the generality of the foregoing, at
the Effective Time, all the property, rights, privileges, powers and franchises
of Healthvision and Eclipsys shall vest in the Surviving Corporation, and all
debts, liabilities and duties of Healthvision and Eclipsys shall become the
debts, liabilities and duties of the Surviving Corporation and Eclipsys's
outstanding equity interest in Healthvision shall be cancelled without
consideration.

     1.4 Certificate of Incorporation; Bylaws.

         (a) At the Effective Time, the Certificate of Incorporation of
Eclipsys, as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law and such Certificate of Incorporation of the
Surviving Corporation.

         (b) At the Effective Time, the Bylaws of Eclipsys, as in effect
immediately prior to the Effective Time, shall be the Bylaws of the Surviving
Corporation until thereafter amended.

     1.5 Directors and Officers. The initial directors of the Surviving
Corporation shall be the directors of Eclipsys immediately prior to the
Effective Time, until their respective successors are duly elected or appointed
and qualified. The initial officers of the Surviving Corporation shall be the
officers of Eclipsys immediately prior to the Effective Time, until their
respective successors are duly appointed.

     1.6 Effect on Capital Stock. Subject to the terms and conditions of this
Agreement, at the Effective Time, capital stock and rights to purchase capital
stock will, by virtue of the Healthvision Merger, be treated as follows:

         1.6.1 Conversion of Healthvision Preferred Stock. At the Effective
Time, the shares of each outstanding series of Preferred Stock of Healthvision,
$0.01 par value per share ("HEALTHVISION PREFERRED STOCK") shall be converted
into Neoforma Common Stock, $0.001 par value ("NEOFORMA COMMON STOCK"), in the
manner provided for in this Agreement. Accordingly, at the Effective Time each
share of Healthvision Preferred Stock issued and outstanding immediately prior
thereto (other than shares for which the holder has exercised dissenters' rights
of appraisal) shall be canceled and converted as follows:

              (a) each share of Healthvision's Series A Convertible
Participating Preferred Stock ("SERIES A STOCK") shall automatically be
converted in the Healthvision Merger into (i) .3041825 of a share (such fraction
representing $10 divided by $32-7/8ths) of Neoforma Common Stock plus (ii) four
shares of Healthvision Common Stock (subject to further


<PAGE>   74

conversion as provided in Section 1.6.2 below);

              (b) each outstanding share of Healthvision's Series B Convertible
Preferred Stock ("SERIES B STOCK"), if any, will be converted in the
Healthvision Merger into four shares of Healthvision Common Stock (subject to
further conversion as provided in Section 1.6.2 below).

         1.6.2 Conversion of Shares of Healthvision Common Stock. Each share of
Common Stock of Healthvision, $0.01 par value per share ("HEALTHVISION COMMON
STOCK") (including Healthvision Common Stock issued or issuable as a result of
the automatic conversion of outstanding shares of Series A Stock into
Healthvision Common Stock at the Effective Time as described in Section
1.6.1(a)(ii) above and the conversion of any outstanding shares of Series B
Stock into Healthvision Common Stock at the Effective Time as described in
Section 1.6.1(b) above), that is issued and outstanding immediately prior to the
Effective Time (in each case, other than Dissenting Shares) will, by virtue of
the Healthvision Merger and at the Effective Time, and without further action on
the part of any holder thereof, be converted into 0.454 (the "EXCHANGE RATIO")
fully paid and nonassessable shares of Neoforma Common Stock. No fraction of a
share of Neoforma Common Stock will be issued by virtue of the Healthvision
Merger, but in lieu thereof, a cash payment shall be made pursuant to Section
1.7(e).

         1.6.3 Assumptions of Options. At the Effective Time, Neoforma will
assume all options to purchase Healthvision common stock outstanding at the
Effective Time (the "HEALTHVISION OPTIONS") pursuant to Healthvision's 1999
Stock Incentive Plan ("1999 PLAN"). At the Effective Time, each Healthvision
Option shall be converted into an option (a "NEOFORMA OPTION"), to purchase that
number of shares of Neoforma Common Stock that is equal to the number of shares
of Healthvision Common Stock that could be purchased pursuant to such
Healthvision Option immediately prior to the Effective Time multiplied by the
Exchange Ratio, with fractional shares being rounded down to the nearest whole
share. The exercise price per share of Neoforma Common Stock purchasable under
each Healthvision Option assumed and converted into a Neoforma Option shall be
equal to the exercise price per share of Healthvision Common Stock under such
Healthvision Option immediately prior to the Effective Time divided by the
Exchange Ratio, rounded up to the nearest cent. No cash will be paid in lieu of
fractional shares which are rounded down pursuant to this Section. The term,
exercisability, vesting schedule, status as an "incentive stock option" under
Section 422A of the Code, if applicable, and all other terms of Healthvision
Options will otherwise be unchanged. Continuous employment with Healthvision
will be credited to an optionee for purposes of determining the number of shares
subject to exercise after the Effective Time. Neoforma agrees to file with the
Securities and Exchange Commission ("SEC") a registration statement on Form S-8
for the shares of Neoforma Common Stock issuable with respect to assumed
Healthvision Options as soon as is reasonably practicable after the Effective
Time, and maintain the effectiveness of such registration statement thereafter
for so long as any of such options or other rights remain outstanding, and will
reserve a sufficient number of shares of Neoforma Common Stock for issuance upon
exercise thereof.

         1.6.4 Assumptions of Healthvision Warrants. At the Effective Time,
Neoforma will assume all outstanding warrants to purchase capital stock of
Healthvision ("HEALTHVISION WARRANTS"). Each Healthvision Warrant shall be
automatically exchanged for a five-year
<PAGE>   75

warrant in substantially the form of Exhibit 1.6.4 (a "NEOFORMA WARRANT"), to
purchase that number of shares of Neoforma Common Stock that is equal to the
number of shares of Healthvision Common Stock (assuming Series B Stock has been
previously issued and automatically converted into Healthvision Common Stock)
that could be purchased pursuant to each such Healthvision Warrant immediately
prior to the Effective Time multiplied by the Exchange Ratio, with fractional
shares being rounded down to the nearest whole share. The exercise price per
share for each such substituted Neoforma Warrant shall equal $3.75 divided by
the Exchange Ratio, rounded up to the nearest cent. No cash will be paid in lieu
of fractional shares which are rounded down pursuant to this Section.

         1.6.5 Cancellation of Healthvision Owned and Eclipsys Owned Stock. Each
share of Healthvision capital stock held by Healthvision or owned by Eclipsys or
any direct or indirect wholly owned subsidiary of Eclipsys or Healthvision
immediately prior to the Effective Time shall be canceled and extinguished
without any conversion thereof.

         1.6.6 Capital Stock of Eclipsys. Each share of common stock, par value
$0.01 per share, of Eclipsys (the "ECLIPSYS COMMON STOCK"), issued and
outstanding after the Eclipsys Merger and immediately prior to the Effective
Time of the Healthvision Merger shall be converted into one validly issued,
fully paid and nonassessable share of common stock, $0.01 par value per share,
of the Surviving Corporation. Following the Effective Time, each certificate
evidencing ownership of shares of Eclipsys common stock shall evidence ownership
of such shares of common stock of the Surviving Corporation.

         1.6.7 Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect appropriately the effect of any stock split, reverse stock
split, stock dividend (including any dividend or distribution of securities
convertible into Neoforma Common Stock or Healthvision Common Stock),
reorganization, recapitalization, reclassification or other like change with
respect to Neoforma Common Stock or Healthvision Common Stock occurring on or
after the date hereof and prior to the Effective Time.

     1.7 Exchange of Certificates.

         (a) Exchange Agent. Neoforma shall select an institution reasonably
acceptable to Healthvision to act as the exchange agent (the "EXCHANGE AGENT")
in the Healthvision Merger.

         (b) Exchange Fund. Promptly after the Effective Time, Neoforma shall
make available to the Exchange Agent for exchange in accordance with this
Article I, the shares of Neoforma Common Stock (such shares of Neoforma Common
Stock, together with cash in lieu of fractional shares and any dividends or
distributions with respect thereto, are hereinafter referred to as the "EXCHANGE
FUND") issuable pursuant to Section 1.6 in exchange for outstanding shares of
Healthvision Common Stock and/or Healthvision Preferred Stock (collectively,
"HEALTHVISION STOCK").

         (c) Exchange Procedures. Promptly after the Effective Time, Neoforma
shall instruct the Exchange Agent to mail to each holder of record of a
certificate or certificates ("CERTIFICATES") which immediately prior to the
Effective Time represented outstanding shares of
<PAGE>   76

Healthvision Stock whose shares were converted into shares of Neoforma Common
Stock pursuant to Section 1.6, (i) a letter of transmittal in customary form
(that shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon proper delivery of the Certificates to
the Exchange Agent and shall contain such other provisions as Neoforma may
reasonably specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for certificates representing shares of Neoforma
Common Stock. Upon surrender of Certificates for cancellation to the Exchange
Agent together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the holders of such
Certificates shall be entitled to receive in exchange therefor certificates
representing the number of whole shares of Neoforma Common Stock into which
their shares of Healthvision Stock were converted at the Effective Time, payment
in lieu of fractional shares that such holders have the right to receive
pursuant to Section 1.7(e) and any dividends or distributions payable pursuant
to Section 1.7(d), and the Certificates so surrendered shall forthwith be
canceled. Until so surrendered, outstanding Certificates will be deemed from and
after the Effective Time, for all corporate purposes, to evidence only the
ownership of the number of full shares of Neoforma Common Stock into which such
shares of Healthvision Stock shall have been so converted and the right to
receive an amount in cash in lieu of the issuance of any fractional shares in
accordance with Section 1.7(e) and any dividends or distributions payable
pursuant to Section 1.7(d). No interest will be paid or accrued on any cash in
lieu of fractional shares of Neoforma Stock or on any unpaid dividends or
distributions payable to holders of Certificates. In the event of a transfer of
ownership of shares of Healthvision Stock which is not registered in the
transfer records of Healthvision, a certificate representing the proper number
of shares of Neoforma Common Stock may be issued to a transferee if the
Certificate representing such shares of Healthvision Stock is presented to the
Exchange Agent, accompanied by all documents required to evidence and effect
such transfer and by evidence that any applicable stock transfer taxes have been
paid.

         (d) Distributions With Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the date of this Agreement with
respect to Neoforma Stock with a record date after the Effective Time will be
paid to the holders of any unsurrendered Certificates with respect to the shares
of Neoforma Common Stock represented thereby until the holders of record of such
Certificates shall surrender such Certificates. Subject to applicable law,
following surrender of any such Certificates, the Exchange Agent shall deliver
to the holders of certificates representing whole shares of Neoforma Common
Stock issued in exchange therefor, without interest, (i) promptly, the amount of
any cash payable with respect to a fractional share of Neoforma Common Stock to
which such holder is entitled pursuant to Section 1.7(e) and the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of Neoforma Common Stock, and
(ii) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time but prior to surrender
and a payment date occurring after surrender, payable with respect to such whole
shares of Neoforma Common Stock.

         (e) Fractional Shares.

              (i) As promptly as practicable following the Effective Time, the
Exchange Agent shall determine the excess of (A) the number of full shares of
Neoforma Common Stock delivered to the Exchange Agent pursuant to Section
1.7(b), over (B) the aggregate number of
<PAGE>   77

full shares of Neoforma Common Stock to be distributed to holders of
Healthvision Stock pursuant to Section 1.7(c) (such excess, the "EXCESS
SHARES"). Following the Effective Time, the Exchange Agent, as agent for the
holders of Healthvision Stock, shall sell the Excess Shares at then prevailing
prices on the Nasdaq Stock Market in the manner set forth in paragraph (ii) of
this Section 1.7(e).

              (ii) The sale of the Excess Shares by the Exchange Agent shall be
executed on the Nasdaq Stock Market and shall be executed in round lots to the
extent practicable. The Exchange Agent shall use all commercially reasonable
efforts to complete the sale of the Excess Shares as promptly following the
Effective Time as, in the Exchange Agent's reasonable judgment, is practicable
consistent with obtaining the best execution of such sales in light of
prevailing market conditions. Until the net proceeds of such sales have been
distributed to the holders of Healthvision Stock, the Exchange Agent will hold
such proceeds in trust for the holders of Healthvision Stock. The Exchange Agent
will determine the portion of such net proceeds to which each holder of
Healthvision Stock shall be entitled, if any, by multiplying the amount of the
aggregate net proceeds by a fraction the numerator of which is the amount of the
fractional share interest to which such holder of Healthvision Stock is entitled
(after taking into account all shares of Neoforma Common Stock to be issued to
such holder) and the denominator of which is the aggregate amount of fractional
share interests to which all holders of Healthvision Stock are entitled. As soon
as practicable after the determination of the amount of cash, if any, to be paid
to holders of Healthvision Stock with respect to fractional share interests, the
Exchange Agent shall promptly pay such amounts to such holders of Healthvision
Stock in accordance with the terms of Section 1.7(c).

              (iii) Notwithstanding the provisions of paragraphs (i) and (ii) of
this Section 1.7(e), Neoforma may decide, at its option, exercised prior to the
Effective Time, in lieu of the issuance and sale of Excess Shares and the making
of the payments contemplated in such paragraphs, that Neoforma shall pay to the
Exchange Agent an amount sufficient for the Exchange Agent to pay each holder of
Healthvision Common Stock the amount such holder would have received pursuant to
Section 1.7(e)(ii) assuming that the sales of Neoforma Common Stock were made at
a price equal to the average of the closing prices of the Neoforma Common Stock
on the Nasdaq Stock Market for the ten consecutive trading days immediately
following the Effective Time and, in such case, all references herein to the
cash proceeds of the sale of the Excess Shares and similar references shall be
deemed to mean and refer to the payments calculated as set forth in this
paragraph (iii). In such event, Excess Shares shall not be issued or otherwise
transferred to the Exchange Agent pursuant to Sections 1.7(b) or (e).

         (f) Required Withholding. Each of the Exchange Agent, Neoforma and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to any
holder or former holder of Healthvision Common Stock such amounts as may be
required to be deducted or withheld therefrom under the Code or under any
provision of state, local or foreign tax law or under any other applicable
federal, state, local, municipal, foreign or other law, statute, constitution,
principle of common law, resolution, ordinance, code, edict, decree, rule,
regulation, ruling or requirement issued, enacted, adopted, promulgated,
implemented or otherwise put into effect by or under the authority of any court,
administrative agency or commission or other governmental authority or
instrumentality, foreign or domestic. To the extent such amounts are so deducted
or withheld,

such amounts shall be treated for all purposes under this Agreement as having
been paid to the person to whom such amounts would otherwise have been paid.

         (g) Lost, Stolen or Destroyed Certificates. In the event that any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, certificates
representing the shares of Neoforma Common Stock into which the shares of
Healthvision Stock represented by such Certificates were converted pursuant to
Section 1.6, cash for fractional shares, if any, as may be required pursuant to
Section 1.7(e) and any dividends or distributions payable pursuant to Section
1.7(d); provided, however, that Neoforma may, in its discretion and as a
condition precedent to the issuance of such certificates representing shares of
Neoforma Common Stock, cash and other distributions, require the owner of such
lost, stolen or destroyed Certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made against
Neoforma, the Surviving Corporation or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

         (h) No Liability. Notwithstanding anything to the contrary in this
Section 1.7, neither the Exchange Agent, Neoforma, the Surviving Corporation nor
any party hereto shall be liable to a holder of shares of Neoforma Common Stock
or Healthvision Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

         (i) Termination of Exchange Fund. Any portion of the Exchange Fund
which remains undistributed to the holders of Healthvision Stock for six months
after the Effective Time shall be delivered to Neoforma, upon demand, and any
holders of Healthvision Stock who have not theretofore complied with the
provisions of this Section 1.7 shall thereafter look only to Neoforma for the
shares of Neoforma Common Stock, any cash in lieu of fractional shares of
Neoforma Common Stock to which they are entitled pursuant to Section 1.7(e) and
any dividends or other distributions with respect to Neoforma Common Stock to
which they are entitled pursuant to Section 1.7(d), in each case, without any
interest thereon.

     1.8 No Further Ownership Rights in Healthvision Stock. All shares of
Neoforma Common Stock issued in accordance with the terms hereof (including any
cash paid in respect thereof pursuant to Sections 1.7(d) and (e)) shall be
deemed to have been issued in full satisfaction of all rights pertaining to such
shares of Healthvision Stock, and there shall be no further registration of
transfers on the records of the Surviving Corporation of shares of Healthvision
Stock that were outstanding immediately prior to the Effective Time. If after
the Effective Time Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article I.

     1.9 Restricted Stock. If any shares of Healthvision Common Stock that are
outstanding immediately prior to the Effective Time are unvested or are subject
to a repurchase option, risk of forfeiture or other condition providing that
such shares ("HEALTHVISION RESTRICTED STOCK") may be forfeited or repurchased by
Healthvision upon any termination of the stockholders' employment, directorship
or other relationship with Healthvision (and/or any affiliate of Healthvision)
under the terms of any restricted stock purchase agreement or other agreement
with Healthvision that does not by its terms provide that such repurchase
option, risk
<PAGE>   79

of forfeiture or other condition lapses upon consummation of the Healthvision
Merger, then the shares of Neoforma Common Stock issued upon the conversion of
such shares of Healthvision Common Stock in the Healthvision Merger will
continue to be unvested and subject to the same repurchase options, risks of
forfeiture or other conditions following the Effective Time, and the
certificates representing such shares of Neoforma Common Stock may accordingly
be marked with appropriate legends noting such repurchase options, risks of
forfeiture or other conditions. Healthvision shall take all actions that may be
necessary to ensure that, from and after the Effective Time, Neoforma is
entitled to exercise any such repurchase option or other right set forth in any
such restricted stock purchase agreement or other agreement.

     1.10 Tax Consequences. It is intended by the parties hereto that the
Healthvision Merger shall constitute a "reorganization" within the meaning of
Section 368 of the Code. It is intended by the parties that the Healthvision
Merger shall qualify for accounting treatment as a purchase.

     1.11 Taking of Necessary Action; Further Action. If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Healthvision and Eclipsys, the officers and directors of
Healthvision and Eclipsys will take all such lawful and necessary action.
Neoforma shall cause Eclipsys to perform all of its obligations relating to this
Agreement and the transactions contemplated hereby.

                                   ARTICLE II
                                  MISCELLANEOUS

         2.1 Amendment. Subject to applicable law, this Agreement may be amended
by the parties hereto at any time by execution of an instrument in writing
signed on behalf of each of the parties hereto.

         2.2 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

         2.3 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of law thereof.

         2.4 Assignment. No party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written consent of
the other parties hereto. Subject to the preceding sentence, this Agreement
shall be binding 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.

                          HEALTHVISION VOTING AGREEMENT


     This HEALTHVISION VOTING AGREEMENT (the "AGREEMENT") is made and entered
into as of March 30, 2000, between Neoforma.com, Inc., a Delaware corporation
("NEOFORMA"), and the undersigned stockholder ("STOCKHOLDER") of HEALTHvision,
Inc., a Delaware corporation ("HEALTHVISION").

                                    RECITALS

     A. Concurrently with the execution of this Agreement, Neoforma and
Healthvision are entering into an Agreement and Plan of Merger (the "PLAN")
which provides for the merger of Healthvision with and into Eclipsys Corporation
(the "MERGER"), a Delaware corporation ("ECLIPSYS"), that at the time of the
Merger will be a wholly-owned subsidiary of Neoforma. Pursuant to the Merger,
shares of capital stock of Healthvision will be converted into shares of
Neoforma Common Stock on the basis described in the Plan. Capitalized terms used
but not defined herein shall have the meanings set forth in the Plan.

     B. Stockholder is the record holder of such number of outstanding shares of
capital stock of Healthvision as is indicated on the final page of this
Agreement.

     C. As a material inducement to enter into the Plan, Neoforma desires
Stockholder to agree, and Stockholder is willing to agree, to vote the Shares
(as defined below), and such other shares of capital stock of Healthvision over
which Stockholder has voting power, so as to facilitate consummation of the
Merger.


         In consideration of the foregoing and the representations, warranties,
covenants and agreements set forth in this Agreement, the parties agree as
follows:


     1. AGREEMENT TO VOTE SHARES

         1.1 Definitions. For purposes of this Agreement:

              (a) Shares. The term "SHARES" shall mean all issued and
outstanding shares of Healthvision Common Stock owned of record or beneficially
by Stockholder or over which Stockholder exercises voting power, in each case,
as of the record date for persons entitled (i) to receive notice of, and to vote
at the meeting of the stockholders of Healthvision called for the purpose of
voting on the matters referred to in Section 1.2, or (ii) to take action by
written consent of the stockholders of Healthvision with respect to the matters
referred to in Section 1.2. Stockholder agrees that any shares of capital stock
of Healthvision that Stockholder purchases or with respect to which Stockholder
otherwise acquires beneficial ownership or over which Stockholder exercises
voting power after the execution of this Agreement and prior to the date of
termination of this Agreement pursuant to Section 3 below shall be subject to
the terms and conditions of this Agreement to the same extent as if they
constituted Shares on the date hereof.

              (b) Subject Securities. The term "SUBJECT SECURITIES" shall
mean: (i)

<PAGE>   82

all securities of Healthvision (including all shares of Healthvision Common
Stock and all options, warrants and other rights to acquire shares of
Healthvision Common Stock) beneficially owned by Stockholder as of the date of
this Agreement; and (ii) all additional securities of Healthvision (including
all additional shares of Healthvision Common Stock and all additional options,
warrants and other rights to acquire shares of Healthvision Common Stock) of
which Stockholder acquires ownership during the period from the date of this
Agreement through the earlier of termination of this Agreement pursuant to
Section 3 below or the record date for the meeting at which stockholders of
Healthvision are asked to vote upon approval of the Plan and the Merger.

              (c) Transfer. Stockholder shall be deemed to have effected a
"TRANSFER" of a security if Stockholder directly or indirectly: (i) sells,
pledges, encumbers, transfers or disposes of, or grants an option with respect
to, such security or any interest in such security; or (ii) enters into an
agreement or commitment providing for the sale, pledge, encumbrance, transfer or
disposition of, or grant of an option with respect to, such security or any
interest therein.

         1.2 Agreement to Vote Shares. Stockholder hereby covenants and agrees
that, during the period commencing on the date hereof and continuing until the
first to occur of (i) such date and time as the Merger shall become effective in
accordance with the terms and provisions of the Plan (the "EFFECTIVE TIME") and
(ii) termination of this Agreement in accordance with its terms, at any meeting
(whether annual or special and whether or not an adjourned or postponed meeting)
of the stockholders of Healthvision, however called, or in connection with any
written consent of the stockholders of Healthvision, Stockholder will appear at
the meeting or otherwise cause the Shares to be counted as present thereat for
purposes of establishing a quorum and vote or consent (or cause to be voted or
consented) the Shares:

               (1) in favor of the approval and adoption of the Plan in the form
          entered into on the date hereof and the agreement of merger to be
          filed with the Delaware Secretary of State (the "AGREEMENT OF MERGER")
          a form of which is attached as an exhibit to the Plan, and the
          approval of the Merger and the other actions contemplated by the Plan
          and the Agreement of Merger and any actions required in furtherance
          thereof;

               (2) against approval of any proposal made in opposition to or in
          competition with the consummation of the Merger, including, without
          limitation, any Acquisition Proposal or any action or agreement that
          would result in a breach in any respect of any covenant,
          representation or warranty or any other obligation or agreement of
          Healthvision under the Plan or the Agreement of Merger, or of
          Stockholder under this Agreement.

         Stockholder further agrees not to enter into any agreement or
understanding with any person the effect of which would be inconsistent with or
violative of any provision contained in this Section 1.2.

         1.3. Transfer and Other Restrictions. (a) Prior to the termination of
this Agreement, Stockholder agrees not to, directly or indirectly:





                                        2
<PAGE>   83



                    (i) except pursuant to the terms of the Plan, offer for
               sale, Transfer or otherwise dispose of, or enter into any
               contract, option or other arrangement or understanding with
               respect to or consent to the offer for sale Transfer or other
               disposition of any or all of the Subject Securities or any
               interest therein except as provided in Section 1.2 hereof;

                    (ii) grant any proxy, power of attorney, deposit any of the
               Subject Securities into a voting trust or enter into a voting
               agreement or arrangement with respect to the Subject Securities
               except as provided in this Agreement; or

                    (iii) take any other action that would make any
               representation or warranty of Stockholder contained herein untrue
               or incorrect or have the effect of preventing or disabling
               Stockholder from performing its obligations under this Agreement.

         (b) To the extent Stockholder is, as of the date hereof, party to a
contract or agreement that requires Stockholder to Transfer Subject Securities
to another person or entity (excluding a contract or agreement pledging Subject
Securities to Healthvision), Stockholder will not effect any such Transfer
unless and until the transferee agrees to be bound by and executes an agreement
in the form of this Agreement with respect to the Subject Securities to be
Transferred. Nothing herein shall prohibit Stockholder from exercising (in
accordance with the terms of the option or warrant, as applicable) any option or
warrant Stockholder may hold; provided that the securities acquired upon such
exercise shall be deemed Subject Securities and Shares hereunder.

         (c) Until July 24, 2000, Stockholder will not, directly or indirectly,
(i) offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant for the sale of, or otherwise dispose of or transfer any shares of the
Neoforma Common Stock issued to such Stockholder in the Merger or any securities
received by such Stockholder in the Merger convertible into or exchangeable or
exercisable for Neoforma Common Stock, or (ii) enter into any swap or any other
agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of the Neoforma Common Stock
issued in the Merger, whether any such swap or transaction is to be settled by
delivery of Neoforma Common Stock or other securities, in cash or otherwise. The
foregoing sentence shall not apply to (a) transactions relating to Neoforma
Common Stock acquired by Stockholder other than pursuant to the Merger, (b) the
transfer, if the undersigned is an individual, to a member or members of his or
her immediate family or to a trust, the beneficiaries of which are exclusively
the undersigned and/or a member or members of his or her immediate family,
either during his or her lifetime or on death by will or intestacy, provided
that the transferee or transferees thereof agree in writing to be bound by the
provisions of this Agreement, or (c) the transfer, if the undersigned is a
partnership, corporation or trust, to partners (or retired partners who retire
after the date hereof), shareholders, or beneficiaries, as the case may be, of
the undersigned as a distribution, provided that the distributees thereof agree
in writing to be bound by the provisions of this Agreement. For the purposes of
this paragraph, "immediate family" shall mean spouse, lineal descendant, father,
mother, brother or sister of the transferor.

         1.4 Irrevocable Proxy. Concurrently with the execution of this

attached hereto as Exhibit I (the "PROXY"), which shall be irrevocable to the
extent set forth therein, with respect to the Shares.

         (a) Stockholder is the record and beneficial owner of, or Stockholder
exercises voting power over, the shares of Healthvision capital stock indicated
on the final page of this Agreement, which, on and as of the date hereof, are
free and clear of any Encumbrances that would adversely affect the ability of
Stockholder to carry out the terms of this Agreement. The number of Shares set
forth on the signature pages hereto are the only Shares beneficially owned by
such Stockholder and, except as set forth on such signature pages, the
Stockholder holds no options to purchase or rights to subscribe for or otherwise
acquire any securities of Healthvision and has no other interest in or voting

the consummation by such Stockholder of the transactions contemplated by this
Agreement have been duly authorized by all necessary action (including any
consultation, approval or other action by or with any other person). This
Agreement has been duly executed and delivered by such Stockholder and
constitutes a valid and binding obligation of such Stockholder, enforceable
against such Stockholder in accordance with its terms. The execution and
delivery of this Agreement does not, and the consummation of the transactions
contemplated by this Agreement and compliance with the provisions of this
Agreement will not, conflict with, or result in any violation of, or default

right of termination, cancellation or acceleration of any obligation which would
result in the creation of any Encumbrance upon any of the Shares owned by such
Stockholder under, any provision of Stockholder's charter documents (if
applicable), applicable law or regulation or of any agreement, judgment,
injunction, order, decree, or other instrument binding on such Stockholder or
any Shares owned by such Stockholder. No consent, approval, order or
authorization of, or registration, declaration or filing with or exemption by
any Governmental Entity is required by or with respect to such Stockholder in
connection with the execution and delivery of this Agreement by such Stockholder

thereunder. If this Agreement is being executed in a representative or fiduciary
capacity, the person signing this Agreement has full power and authority to
enter into and perform such Agreement.

     3. TERMINATION

the event that the Plan is modified in a manner that is materially adverse to
Stockholder without Stockholder's consent.

reorganization, spin-off, recapitalization, reclassification or other like
change with respect to Common Stock occurring on or after the date hereof and

Number will be equitably adjusted to account for such changes.

         (b) VHA shall require any proposed transferee of Shares that are

Stock into securities of a person other than Parent is consummated, the
provisions of this Section regarding forfeiture of Shares shall terminate,

Warrants and the consummation of the transactions contemplated hereby and
thereby have been duly authorized by all necessary corporate action on the part
of Parent, subject only to the approval by Parent's stockholders of the issuance
of Common Stock pursuant to this Agreement and the Warrants. The affirmative

STOCKHOLDERS' MEETING") is sufficient for Parent's stockholders to approve the
issuance of Common Stock pursuant to this Agreement and the Warrants, and no
other approval of any holder of any securities of Parent is required in
connection with the consummation of the transactions contemplated hereby. This

delivered by Parent and, subject to approval of Parent stockholders in the case
of this Agreement and the issuance of the Warrants and, assuming the due
authorization, execution and delivery by Novation, HPPI, VHA and UHC, as
applicable, constitute the valid and binding obligations of Parent, enforceable
against Parent 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.

Agreement by Parent does not, and the performance of this Agreement and the
Outsourcing Agreement by Parent will not, (i) conflict with or violate the
Parent Charter Documents, (ii) subject to obtaining the Parent Stockholder
Approvals and compliance with the requirements set forth in Section 3.4(c),

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 Parent'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 Parent pursuant to, any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Parent is a party or by which Parent or any of its
properties are bound or affected, except, in the case of clauses (ii) and (iii),

which, individually or in the aggregate, would not have a Material Adverse
Effect on Parent. Part 3.4(b) of the Parent Disclosure Letter lists all
consents, waivers and approvals under any of Parent's or any of its

declaration or filing with any court, administrative agency or commission or
other governmental entity or instrumentality, foreign or domestic ("GOVERNMENTAL
ENTITY") is required to be obtained or made by Parent in connection with the

contemplated hereby, 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

<PAGE>   7

or have a material adverse effect on the ability of the parties hereto to
consummate the transactions contemplated hereby.

         3.5 SEC Filings; Parent Financial Statements.

         (a) Parent has filed all forms, reports and documents required to be
filed by Parent with the SEC since the effective date of the Registration
Statement of Parent's initial public offering, and has made available to Parent
such forms, reports and documents in the form filed with the SEC. All such
required forms, reports and documents (including those that Parent may file
subsequent to the date hereof) and the Parent Initial Registration Statement are
referred to herein as the "PARENT SEC REPORTS." As of their respective dates,
the Parent SEC Reports (i) were prepared in accordance with the requirements of
the Securities Act or the Exchange Act, as the case may be, and the rules and
regulations of the SEC thereunder applicable to such Parent SEC Reports, and
(ii) did not at the time they were filed (or if amended or superseded by a
filing prior to the date of this Agreement, then on the date of such filing)
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not

by a subsequently filed Parent SEC Report. None of Parent's subsidiaries is
required to file any forms, reports or other documents with the SEC.


         (b) Each of the consolidated financial statements (including, in each
case, any related notes thereto) contained in the Parent SEC Reports (the

hereof until the Closing, (i) complied as to form in all material respects with
the published rules and regulations of the SEC with respect thereto, (ii) was

on Form 10-Q, 8-K or any successor form under the Exchange Act) and (iii) fairly
presented the consolidated financial position of Parent and its subsidiaries as
at the respective dates thereof and the consolidated results of Parent's
operations and cash flows for the periods indicated, except that the unaudited
interim financial statements may not contain footnotes and were or are subject
to normal and recurring year-end adjustments. The balance sheet of Parent
contained in Parent SEC Reports as of September 30, 1999 is hereinafter referred
to as the "PARENT BALANCE SHEET." Except as disclosed in the Parent Financials,
since the date of the Parent Balance Sheet neither Parent nor any of its
subsidiaries has any liabilities required under GAAP to be set forth on a
balance sheet (absolute, accrued, contingent or otherwise) which are,
individually or in the aggregate, material to the business, results of
operations or financial condition of Parent and its subsidiaries taken as a
whole, except for liabilities incurred since the date of the Parent Balance
Sheet in the ordinary course of business consistent with past practices and
liabilities incurred in connection with this Agreement.

         3.6 Absence of Certain Changes or Events. Since the date of the Parent
Balance Sheet there has not been (i) any Material Adverse Effect with respect to
Parent, (ii) any declaration, setting aside or payment of any dividend on, or
other distribution (whether in cash, stock or property) in respect of, any of
Parent's or any of its subsidiaries' capital stock, or any purchase, redemption
or other acquisition by Parent of any of Parent's capital stock or any other
securities of Parent or its subsidiaries or any options, warrants, calls or
rights to acquire any such shares or other securities except for repurchases
from employees following their termination pursuant to the terms of their
pre-existing stock option or purchase agreements, (iii) any split,

                                       7

capital stock, (iv) any granting by Parent or any of its subsidiaries of any
increase in compensation or fringe benefits to any of their officers or
employees, or any payment by Parent or any of its subsidiaries of any bonus to
any of their officers or employees, or any granting by Parent or any of its
subsidiaries of any increase in severance or termination pay or any entry by
Parent or any of its subsidiaries into, or material modification or amendment
of, any currently effective employment, severance, termination or
indemnification agreement or any agreement the benefits of which are contingent
or the terms of which are materially altered upon the occurrence of a
transaction involving Parent of the nature contemplated hereby, in each case,
other than in the ordinary course of business consistent with past practice, (v)

underwriters of such policies or bonds. All premiums due and payable under all
such policies have been paid and the Parent and its subsidiaries are otherwise
in compliance in all material respects with the terms of such policies and
bonds.

         3.17 Disclosure. The information supplied by Parent for inclusion in
the Registration Statement shall not at the time the Registration Statement is
filed with the SEC and at the time it becomes effective under the Securities Act
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
misleading. The information supplied by Parent for inclusion or incorporation by
reference in the Proxy Statement/Prospectus shall not, on the date the Proxy
Statement/Prospectus 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. The Registration
Statement and Proxy Statement/Prospectus will comply as to form in all material
respects with the provisions of the Securities Act and the rules and regulations
thereunder. If at any time prior to the Closing, any event relating to Parent or
any of its affiliates, officers or directors should be discovered by Parent
which is required to be set forth in an amendment to the Registration Statement
or a supplement to the Proxy Statement/Prospectus, Parent shall promptly inform
Novation. Notwithstanding the foregoing, Parent makes no representation or
warranty with respect to any information supplied by Novation which is contained
in any of the foregoing documents.

                           REPRESENTATIONS, WARRANTIES
                          AND CERTAIN AGREEMENTS OF VHA

     VHA hereby represents and warrants to Parent, subject to the exceptions
specifically disclosed in writing in the disclosure letter delivered by VHA
dated as of the date hereof and certified by a duly authorized officer of VHA
(the "UHC DISCLOSURE LETTER") (which VHA Disclosure Letter shall be deemed to be
representations and warranties to Parent by VHA under this Section 4), as
follows:


                                       17
<PAGE>   18


         4.1 Organization, Good Standing and Qualification. VHA represents that
it is an entity duly organized, validly existing and in good standing under the
laws of the state of its formation and has all requisite power and 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 conducted,
except where the failure to be so organized, existing or in good standing or to
have such power, authority or qualifications would not have a Material Adverse
Effect on VHA.

         4.2 Authorization.

         (a) VHA has all requisite power and authority to enter into this
Agreement and the Outsourcing Agreement and to consummate the transactions
contemplated hereby and thereby. The execution and delivery of this Agreement
and the Outsourcing Agreement and the consummation of the transactions
contemplated 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

                                       18
<PAGE>   19

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, Warrants and Warrant Stock
to be delivered to VHA hereunder will be acquired for investment 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, Warrants or Warrant Stock to be acquired
by VHA hereunder. VHA also represents that it has not been formed for the
specific purpose of acquiring the Shares, Warrants 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 investment decision with respect to the the Shares, Warrants and
Warrant Stock to be issued to VHA under this Agreement. VHA further has had an
opportunity to ask questions and receive answers from Parent regarding the terms
and conditions of the offering of the the Shares, Warrants 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 Investment Experience. VHA understands that an investment in the
Shares, Warrants and Warrant Stock involves substantial risk. VHA: (i) has
experience as an investor in 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 investment in the Shares, Warrants 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 investment in the Shares, Warrants and
Warrant Stock and protecting its own interests in connection with this
investment 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
Warrants are, and upon issuance under the Warrants, 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 Warrants.


                                       19
<PAGE>   20


         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 Warrants are non-transferable to the extent they have
not vested.

         4.10 Legends. VHA understands and agrees that the certificates
evidencing the Shares, the Warrants 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 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 in the
Registration Statement shall not at the time the Registration Statement is filed
with the SEC and at the time it becomes effective under the Securities Act
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
misleading. The information supplied by VHA for inclusion or incorporation by
reference in the Proxy Statement/Prospectus shall not (i) on the date the Proxy
Statement/Prospectus is mailed to Parent's stockholders, and (ii) at the time of
the Parent Stockholders' Meeting to consider the Parent Stockholder Approval 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 Effective Time 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 an amendment to the
Registration Statement or a supplement to the Proxy Statement/Prospectus, 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 any of the foregoing documents.



                                    ARTICLE V

                                   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"), to the extent that the outstanding shares of Common Stock
(including outstanding Warrant Stock) beneficially owned by VHA together with
all "affiliates" (which for purposes of this Agreement shall have the meaning
given such term in Rule 144(a)(1) promulgated under the 1933 Act) of VHA exceeds
10% of the outstanding Common Stock of Parent (the shares in excess of such 10%
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 Stockholders' for approval except for (i) a Change of
Control (as defined below) of Parent, (ii) the election of VHA' designated
nominee 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 preceding sentence, 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, 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

                                       24
<PAGE>   25

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 of all
or substantially all of the assets of Parent.

         6.2 Acquisition of Parent Securities. VHA agrees that from and after
the date of the Closing through the Fifth Anniversary, (i) at any time that VHA
together with all of its affiliates beneficially owns 10% (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"), 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 Warrants, and (ii) at any time
that VHA, together with all of its affiliates beneficially owns less than 10% 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 10% of the outstanding Common Stock of
Parent.

         6.3 Parent Board of Directors; Executive Officers. The Board of
Directors of Parent will take all actions reasonably necessary such that as soon
as practicable following the Closing, (i) the size of Parent's Board of
Directors shall be increased to nine, and the following persons shall be
appointed to Parent's Board of Directors to fill the five vacancies in the
following classes: three persons nominated by Eclipsys, one of whom shall be
Harvey J. Wilson, who shall be appointed to Class III, one of whom shall be
affiliated with General Atlantic Partners, LLC, who shall be appointed to Class
I, and the other of whom shall be appointed to Class II, one person shall be
appointed by Healthvision to Class I, and one person shall be appointed by VHA
to Class I, and (ii) Harvey J. Wilson shall be elected Chairperson of the Board
of Directors of Parent, and Robert Zollars shall be elected Chief Executive
Officer and President of Parent. Under the Parent 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, Parent will take all actions reasonably
necessary to have a person appointed by VHA be a member of Parent's Board of

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 Warrants 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; or

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


                                       28

termination of this Agreement under Section 9.1 will be effective immediately

as set forth in this Section 9.2 and Article 10, each of which shall survive the
termination of this Agreement, and (ii) nothing herein shall relieve any party

         10.7 Expenses; Finder's Fees. All fees and expenses incurred in
connection with this Agreement and the transactions contemplated hereby shall be
paid by the party incurring such expenses whether or not the Closing occurs. VHA
agrees to indemnify and to hold harmless Parent from any liability for any

to be unenforceable under applicable law, such provision(s) shall be excluded
from this Agreement and the balance of the Agreement shall be interpreted as if
such provision(s) were so excluded and shall be enforceable in accordance with

         10.9 Entire Agreement. This Agreement, together with all exhibits and
schedules and disclosure letters delineated pursuant hereto, and the Outsourcing
Agreement constitute the entire agreement and understanding of the parties with
respect to the subject matter hereof and supersedes any and all prior
negotiations, correspondence, agreements, understandings duties or obligations

desirable to confirm and carry out and to effectuate fully the intent and
purposes of this Agreement.

         10.11 Amendment; Extension; Waiver. Subject to applicable law, this
Agreement may be amended by the parties hereto at any time by execution of an

conditions for the benefit of such party contained herein. Any agreement on the
part of a party hereto to any such extension or waiver shall be valid only if

provided herein, any and all remedies herein expressly conferred upon a party
will be deemed cumulative with and not exclusive of any other remedy conferred
hereby, or by law or equity upon such party, and the exercise by a party of any

specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to seek an injunction or injunctions to prevent

or rule of construction providing that ambiguities in an agreement or other
document will be construed against the party drafting such agreement or
document.

         10.14 Parent Disclosure Letter. Disclosure made with regard to a
representation or warranty of Parent in the Parent Disclosure Letter shall also
be deemed to qualify other representations and warranties of the party making
such disclosure if it is readily apparent from the language contained in such
disclosure that such disclosure is applicable to such other representation or
warranty.

         10.15 Waiver Of Jury Trial. EACH OF PARENT AND VHA HEREBY IRREVOCABLY
WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM

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

                               NEOFORMA.COM, INC.

No. V-1                                              Void after __________, 2010


         THIS CERTIFIES THAT VHA Inc, a Delaware corporation (the "HOLDER"), or
its permitted assigns is entitled to purchase under this Warrant up to 6,333,650
shares (the "SHARES") of common stock, par value $0.001 per share ("COMMON
STOCK"), of Neoforma.com, Inc., a Delaware corporation (the "COMPANY") at a per
share price of $30.375 (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 Common Stock and Warrant Agreement dated as of
March 30, 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 vested or
exercisable with respect to any Shares. This Warrant shall become exercisable as
to 20% of aggregate number of Shares (Shares for which this Warrant may be
exercised, "VESTED SHARES") on January 1 of each of 2001, 2002, 2003, 2004 and
2005 if, on each such respective date, the Outsourcing

and Operating Agreement, dated as of March 30, 2000 (the "OPERATING AGREEMENT"),
among the Company, the Holder, University HealthSystems Consortium, an Illinois
corporation, Novation, LLC, a Delaware limited liability company, and Healthcare
Purchasing Partners International, LLC, remains in full force and effect in
accordance with its terms (unless terminated or suspended by the Company in
breach of the provisions thereof); provided, however, that Warrant Shares shall
nevertheless continue to vest as contemplated herein if the Holder shall be a
party to an agreement with the Company which provides Company with substantially
the same benefits as the Operating Agreement which, if and as permitted by the
Operating Agreement, has been entered into upon a change in the Holder's
ownership of Novation, LLC and/or Healthcare Purchasing Partners International,
LLC, the Holder is not in material breach or material default under such
agreement, and such agreement is and shall have been since its inception in full
force and effect in accordance with its terms.

         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 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 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

                                       4
<PAGE>   38

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 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

                                       5
<PAGE>   39

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.

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

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

                      INVESTMENT REPRESENTATION CERTIFICATE


Holder:           VHA Inc.

Company:          Neoforma.com, Inc.

Security:         Common Stock

Amount:

Date:

     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


<PAGE>   45

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 Common Stock and Warrant
Agreement, dated as of March 30, 2000 by and between the Company and Holder, and
acknowledges that Holder is bound by such restrictions.

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

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

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

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 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.

                                       3
<PAGE>   49

          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 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

                                       4
<PAGE>   50

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 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


                                      5
<PAGE>   51

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 or 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.

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

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

the previous sentence, the notice will indicate the expected date of the Notice

                      INVESTMENT REPRESENTATION CERTIFICATE


Holder:   VHA Inc.

Company:  Neoforma.com, Inc.

Security: Common Stock

Amount:

Date:

     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


                                       11
<PAGE>   56

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 Common Stock and Warrant
Agreement, dated as of March 30, 2000 by and between the Company and Holder, and
acknowledges that Holder is bound by such restrictions.

                                    RECITALS

     A. Parent, UHC, Novation, LLC, a Delaware limited liability company

follows:

         3.1 Organization of Parent.

         (a) Parent and each of its subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all requisite corporate power and
authority, and all requisite qualifications to do business as a foreign
corporation, to conduct its business in the manner in which its business is
currently being conducted, except where the failure to be so organized, existing
or in good standing or to have such power, authority or qualifications would
not, individually or in the aggregate, have a Material Adverse Effect on Parent.

         (b) Other than the corporations identified in Part 3.1 of the Parent
Disclosure Letter, neither Parent nor any of the other corporations identified
in Part 3.1 of the Parent

                                       2
<PAGE>   3

nature in, any corporation, partnership, joint venture arrangement or other
business entity, other than the entities identified in Part 3.1 of the Parent

companies as part of the cash management program of Parent. Neither Parent nor
any of its subsidiaries is obligated to make any material future investment in

Warrant and the consummation of the transactions contemplated hereby and thereby
have been duly authorized by all necessary corporate action on the part of
Parent, subject only to the approval by Parent's stockholders of the issuance of

Agreement and the Outsourcing Agreement have each been duly executed and
delivered by Parent and, subject to approval of Parent stockholders in the case
of this Agreement and the issuance of the Warrant and, assuming the due
authorization, execution and delivery by Novation, HPPI, UHC and VHA, as
applicable, constitute the valid and binding obligations of Parent, enforceable
against Parent 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.

Agreement by Parent does not, and the performance of this Agreement and the

declaration or filing with any court, administrative agency or commission or

         (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 years, which
defects, individually or in the aggregate, would have a Material Adverse Effect
on Parent.

         3.10 Compliance with Laws.

         (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
decree applicable to Parent or any of its subsidiaries or by which Parent or any
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

                                       10

a material adverse effect on the ability of the parties hereto to consummate the
transactions contemplated hereby.

<PAGE>   13


         (f) Multiemployer Plans. At no time has Parent contributed to or been
required to contribute to any Multiemployer Plan.

         (g) No Post-Employment Obligations. No Parent Employee Plan provides,

the extent required by statute.

         (h) COBRA; FMLA. Except as would not have a Material Adverse Effect on
Parent, neither Parent nor any Affiliate has, prior to the Closing violated any
of the health care continuation requirements of COBRA, the requirements of FMLA
or any similar provisions of state law applicable to its Employees.

         (i) Effect of Transaction. The execution of this Agreement and the
consummation of the transactions contemplated hereby will not (either alone or
upon the occurrence of any additional or subsequent events) constitute an event
under any Parent Employee Plan, Parent Employee Agreement, trust or loan that
will or may result in any payment (whether of severance pay or otherwise),
acceleration, forgiveness of indebtedness, vesting, distribution, increase in
benefits or obligation to fund benefits with respect to any Parent Employee. No
payment or benefit which will or may be made by Parent or its Affiliates with
respect to any Parent Employee as a result of the transactions contemplated by
this Agreement will be characterized as an "excess parachute payment," within
the meaning of Section 280G(b)(1) of the Code or will be treated as a
nondeductible expense within the meaning of Section 162 of the Code.

         (j) Employment Matters. Except, in each case, as would not,
individually or in the aggregate, have a Material Adverse Effect on Parent,

than routine payments to be made in the normal course of business and consistent
with past practice). There are no pending, or, to Parent's knowledge, threatened
material claims or actions against Parent under any worker's compensation policy
or long-term disability policy. To Parent's knowledge, no Parent Employee has
violated in any material manner any employment contract, nondisclosure agreement
or noncompetition agreement by which such Parent Employee is bound due to such
Parent Employee being employed by Parent and disclosing to Parent or using trade
secrets or proprietary information of any other person or entity.


                                       13
<PAGE>   14


         (k) Labor. No work stoppage or labor strike against Parent is pending,
threatened or reasonably anticipated. Parent does not know of any activities or
proceedings of any labor union to organize any Parent Employees. There are no
actions, suits, claims, labor disputes or grievances pending, or, to the
knowledge of Parent, threatened or reasonably anticipated relating to any labor,
safety or discrimination matters involving any Parent Employee, including
charges of unfair labor practices or discrimination complaints, which, if
adversely determined, would, individually or in the aggregate, result in any
material liability to Parent. Neither Parent nor any of its subsidiaries has
engaged in any unfair labor practices within the meaning of the National Labor
Relations Act. Parent is not presently, nor has it been in the past, a party to,
or bound by, any collective bargaining agreement or union contract with respect
to Employees and no collective bargaining agreement is being negotiated by
Parent.

         (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 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.

         3.14 Certain Agreements. Other than (i) the Eclipsys Merger Agreement,

Letter, any employment agreement or commitment with any officer or member 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 without liability or
financial obligation, except to the extent general principles of wrongful
termination law may limit Parent's or any of its subsidiaries' ability to
terminate employees at will, or any consulting agreement;

         (b) any material agreement of indemnification, any material guaranty or
any material instrument evidencing indebtedness for borrowed money by way of
direct loan, sale of debt securities or purchase money obligation;

         (c) any agreement or obligation containing covenants purporting to
limit or which effectively limit the Parent's or any of its subsidiaries'
freedom to compete in any line of business or in any geographic area or which
would so limit Parent or any of its subsidiaries after the Closing or granting
any exclusive distribution or other exclusive rights;

         (d) any agreement or obligation currently in force relating to the
disposition or acquisition by Parent or any of its subsidiaries after the date
of this Agreement of a material amount of assets not in the ordinary course of
business, or pursuant to which Parent has any material ownership or
participation interest in any corporation, partnership, joint venture, strategic
alliance or other business enterprise other than Parent's subsidiaries;

         (e) any agreement or obligation currently in force to provide source
code to any third party for any product or technology;

         The agreements required to be disclosed in the Parent Disclosure Letter
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
Adverse Effect on Parent. Neither Parent nor any of its subsidiaries, nor to
Parent's knowledge, any other party thereto, is in breach, violation or default
under, and neither Parent nor any of its subsidiaries has received written
notice that it has breached, violated or defaulted, any of the terms or
conditions of any Parent Contract in such a manner as would have a Material
Adverse Effect on Parent.

         3.15 Brokers' and Finders' Fees. Except for fees payable to Merrill
Lynch & Co., Parent has not incurred, nor will it incur, directly or indirectly,
any liability for brokerage or finders' fees or agents' commissions or any

contemplated hereby.

         3.16 Insurance. Parent and each of its subsidiaries have policies of
insurance and bonds of the type and in amounts customarily carried by persons
conducting business or owning assets similar to those of the Parent and its
subsidiaries. There is no material claim

                                       15
<PAGE>   16

pending under any of such policies or bonds as to which coverage has been
questioned, denied or disputed by the underwriters of such policies or bonds.
All premiums due and payable under all such policies have been paid and the
Parent and its subsidiaries are otherwise in compliance in all material respects
with the terms of such policies and bonds.

         3.17 Disclosure. The information supplied by Parent for inclusion in
the Registration Statement shall not at the time the Registration Statement is
filed with the SEC and at the time it becomes effective under the Securities Act
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
misleading. The information supplied by Parent for inclusion or incorporation by
reference in the Proxy Statement/Prospectus shall not, on the date the Proxy
Statement/Prospectus 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. The Registration
Statement and Proxy Statement/Prospectus will comply as to form in all material
respects with the provisions of the Securities Act and the rules and regulations
thereunder. If at any time prior to the Closing, any event relating to Parent or
any of its affiliates, officers or directors should be discovered by Parent
which is required to be set forth in an amendment to the Registration Statement
or a supplement to the Proxy Statement/Prospectus, Parent shall promptly inform
Novation. Notwithstanding the foregoing, Parent makes no representation or

                                   ARTICLE IV
                           REPRESENTATIONS, WARRANTIES
                          AND CERTAIN AGREEMENTS OF UHC

     UHC hereby represents and warrants to Parent, subject to the exceptions
specifically disclosed in writing in the disclosure letter delivered by UHC
dated as of the date hereof and certified by a duly authorized officer of UHC
(the "UHC DISCLOSURE LETTER") (which UHC Disclosure Letter shall be deemed to be
representations and warranties to Parent by UHC under this Section 4), as
follows:

         4.1 Organization, Good Standing and Qualification. UHC represents that
it is an entity duly organized, validly existing and in good standing under the
laws of the state of its formation and has all requisite power and 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 conducted,
except where the failure to be so organized, existing or in good standing or to
have such power, authority or qualifications would not have a Material Adverse
Effect on UHC.

         4.2 Authorization.

         (a) UHC has all requisite power and authority to enter into this
Agreement and the Outsourcing Agreement and to consummate the transactions
contemplated hereby and

                                       16
<PAGE>   17

thereby. The execution and delivery of this Agreement and the Outsourcing
Agreement and the consummation of the transactions contemplated hereby and
thereby have been duly authorized by all necessary action on the part of UHC.
This Agreement and the Outsourcing Agreement have each been duly executed and
delivered by UHC and constitute the valid and binding obligations of UHC,
enforceable against UHC 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 UHC does not, and the performance of this Agreement and the
Outsourcing Agreement by UHC will not, (i) conflict with or violate the
certificate of incorporation, bylaws, operating agreement or other
organizational documents of UHC, (ii) subject to compliance with the
requirements set forth in Section 4.2(c) with regard to UHC, conflict with or
violate any law, rule, regulation, order, judgment or decree applicable to UHC
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 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.

         (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 investment 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.


                                       17
<PAGE>   18


         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 investment 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 Investment Experience. UHC understands that an investment in the
Shares, Warrant and Warrant Stock involves substantial risk. UHC: (i) has
experience as an investor in 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 investment in 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 investment in the Shares, Warrant and
Warrant Stock and protecting its own interests in connection with this
investment 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.

         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:

               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.

The legend set forth 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 UHC for inclusion in the
Registration Statement shall not at the time the Registration Statement is filed
with the SEC and at the time it becomes effective under the Securities Act
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
misleading. The information supplied by UHC for inclusion or incorporation by
reference in the Proxy Statement/Prospectus shall not (i) on the date the Proxy
Statement/Prospectus is mailed to Parent's stockholders, and (ii) at the time of
the Parent Stockholders' Meeting to consider the Parent Stockholder Approval 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 Effective Time 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 an amendment to the
Registration Statement or a supplement to the

                                       19
<PAGE>   20

Proxy Statement/Prospectus, 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 any of the foregoing
documents.

Outsourcing Agreement constitute the entire agreement and understanding of the
parties with respect to the subject matter hereof and supersedes any and all

                                                                 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 PURCHASE AGREEMENT BETWEEN THE ORIGINAL HOLDERS OF THESE SECURITIES AND
THE ISSUER, A COPY OF WHICH MAY BE OBTAINED FROM THE ISSUER.


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

No. U-1                                              Void after __________, 2010


         THIS CERTIFIES THAT University Healthsystem Consortium, an Illinois
corporation (the "Holder"), or its permitted assigns is entitled to purchase
under this Warrant up to 1,524,477 shares (the "SHARES") of common stock, par
value $0.001 per share ("COMMON STOCK"), of Neoforma.com, Inc., a Delaware
corporation (the "COMPANY") at a per share price of $30.375 (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 Common Stock and Warrant Agreement dated as of
March 30, 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 vested or
exercisable with respect to any Shares. This Warrant shall become exercisable as
to 20% of the aggregate number of Shares (Shares for which this Warrant may be
exercised, "VESTED SHARES") on January


<PAGE>   32

1 of each of 2001, 2002, 2003, 2004 and 2005 if on each such respective date,
the Outsourcing and Operating Agreement, dated as of March 30, 2000 (the
"OPERATING AGREEMENT"), among the Company, the Holder, VHA Inc., a Delaware
corporation, Novation, LLC, a Delaware limited liability company, and Healthcare
Purchasing Partners International, LLC, remains in full force and effect in
accordance with its terms (unless terminated or suspended by the Company in
breach of the provisions thereof); provided, however, that Warrant Shares shall
nevertheless continue to vest as contemplated herein if the Holder shall be a
party to an agreement with the Company which provides the Company with
substantially the same benefits as the Operating Agreement which, if and as
permitted by the Operating Agreement, has been entered into upon a change in the
Holder's ownership of Novation, LLC and/or Healthcare Purchasing Partners
International, LLC, the Holder is not in material breach or material default
under such agreement, and such agreement is and shall have been since its
inception in full force and effect in accordance with its terms.

         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. 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 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.


                                       3
<PAGE>   34


         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 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

                                       4
<PAGE>   35

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 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

                                       5
<PAGE>   36

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 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.

Security:         Common Stock

Amount:

Date:

     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

                                       10

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 Common Stock and Warrant
Agreement, dated as of March 30, 2000 by and between the Company and Holder, and
acknowledges that Holder is bound by such restrictions.

        NEOFORMA.COM, ECLIPSYS AND HEALTHVISION TO MERGE; SIGN EXCLUSIVE
     E-COMMERCE AGREEMENT WITH NOVATION FOR 6,500 HEALTHCARE ORGANIZATIONS

SANTA CLARA, CA, DELRAY BEACH, FL AND IRVING, TX -- MARCH 30, 2000 --
Neoforma.com, Inc. (NASDAQ: NEOF), Eclipsys Corporation (NASDAQ: ECLP) and
HEALTHvision, Inc., today announced the signing of definitive agreements to
merge and create a new company serving the e-healthcare business-to-business
(B2B) marketplace. In conjunction with the agreements, Neoforma.com announced
that it has signed an exclusive 10-year strategic agreement to provide
e-commerce services for the 6,500 healthcare organizations participating in the
purchasing programs of Novation, LLC, the world's largest buyer of medical
supplies and the supply company of national healthcare alliances VHA Inc. and
University HealthSystems Consortium (UHC).

Neoforma.com is a leading provider of B2B e-commerce services in the healthcare
industry. Eclipsys is a leading provider of end-to-end healthcare information
solutions that enable balanced and improved clinical, financial and
patient-satisfaction outcomes. HEALTHvision is a privately held Internet
healthcare company affiliated with Eclipsys and VHA that provides Web-based
solutions exclusively to local healthcare organizations to connect them with
their key constituents.

Under the terms of the agreements, Eclipsys shareholders will receive 1.344
shares of Neoforma.com common stock for each share of Eclipsys, and HEALTHvision
shareholders will receive 0.444 shares of Neoforma.com common stock for each
share of HEALTHvision not owned by Eclipsys or VHA. Including warrants, VHA and
UHC will receive 58.6 million and 10.7 million shares, respectively, of
Neoforma.com common stock. Completion of the transactions, which will be
accounted for as purchase transactions, is expected mid-year, subject to
regulatory and shareholder approvals. On a pro forma basis, including shares
issuable upon exercise of options and warrants, the new company will have
approximately 210.0 million fully converted shares outstanding. The new company
will be referred to as "Neoforma.com" until a new name is selected.

"The challenge facing the healthcare industry is improving the quality of care
while reducing the cost of its delivery," said Harvey J. Wilson, Eclipsys
chairman and chief executive officer, who will become chairman of the new
company. "Separately, the three organizations are effectively addressing this
issue with complementary expertise. The most effective solution requires an
integrated approach, featuring aggressive use of the Internet to combine B2B
Internet connectivity and end-to-end information flow. By merging the
organizations, the new company catapults to a leadership position in the
e-health marketplace, enabling us to drive the healthcare revolution with local
focus and an established global presence."

According to Bob Zollars, chairman, president and chief executive officer of
Neoforma.com who will become CEO and president of the new company, "We are
extremely excited to offer an unparalleled array of new e-commerce services to
UHC, VHA and other healthcare customers around the world. From Web-based
clinical solutions to innovative supply-chain initiatives, this new company's
breadth of offering will


                                       3

<PAGE>   2

be unsurpassed. In addition, we will combine an ASP model, with net transaction
fee revenues, across a highly recurring revenue base."

NOVATION AGREEMENT

The agreement with Novation creates immediate scale for Neoforma.com's
e-commerce platform, as Novation represents more than 30% of U.S. procurement in
healthcare with a membership that includes many of the nation's largest and most
respected healthcare organizations and physicians. Novation also brings an
existing base of relationships with a wide range of healthcare suppliers,
essential to the success of an e-commerce offering and will be active in
recruiting other suppliers to the Neoforma.com marketplace.

Novation already provides the alliance members with highly regarded and utilized
Web-enabled tools, including an online catalog, Web-based cross referencing and
Web tools for standardization. According to Mark McKenna, Novation president,
"We are already an intermediary in this market, and e-commerce is a logical
extension of Novation's core competency of aggregating purchases to reduce
supply costs. The Neoforma.com agreement makes it possible to streamline this
process and create new value for our stakeholders."

In describing the agreement with Neoforma.com, McKenna indicated, "Outsourcing
e-commerce services with an established e-commerce platform enables us to gain
immediate access to the technology and infrastructure required. This will allow
the alliance members to immediately benefit from the reduced procurement costs
and timely access to aggregated purchasing information made possible by the
Internet."

VHA executive vice president Curt Nonomaque noted, "This agreement also builds
on our existing relationships with Eclipsys and HEALTHvision, which provide our
members with care and revenue-workflow solutions that enable them to connect
with their physicians, patients and communities. The combination of these three
companies will enable connectivity among our members' procurement, workflow and
outreach processes."

OVERVIEW OF NEW VENTURE

As a result of the agreement, the new company will represent:

o    An unprecedented alliance that will enable companies to rapidly build and
     launch B2B marketplaces. By adding the complementary solutions offered by
     Eclipsys and HEALTHvision to that of Neoforma.com, customers can be fully
     resourced to dramatically cut costs while improving the quality of and
     satisfaction with care.

o    An integrated set of information solutions that provide a comprehensive
     open marketplace Internet-enabled platform, through which Neoforma.com's
     existing base of suppliers can interface with the extensive Novation
     procurement system of supply partners and buyers.

o    A network of over 40,000 physicians consisting of physician practices
     served by VHA, and EquipMD, a physician procurement e-commerce company that
     Neoforma.com has agreed to acquire.

o    A skilled workforce of over 2,000 employees, including clinicians and other
     healthcare professionals worldwide who provide technology development,
     systems integration, hosting, marketing, operations and support services.

Wilson said the new company will continue to offer the end-to-end solutions
pioneered by Eclipsys, Neoforma.com and HEALTHvision and will begin
cross-selling the Internet-enabling services of the three companies once the
merger is complete.

In addition to the Neoforma.com platform addressing the healthcare purchasing
lifecycle, the new company will provide Eclipsys' Sunrise line of integrated,
knowledge-based applications; its leading-edge eWebIT systems-integration
capabilities; and its comprehensive information-management services, including
application services provider (ASP), business process reengineering, network
services and full IT

                                       4

outsourcing. Also immediately available will be HEALTHvision's fast-growing
range of customized, locally branded Web offerings and other Internet-based
healthcare solutions that connect healthcare organizations with their key
constituents and enable secure, interactive patient care.

Zollars stated that "Because the combined companies bring to the new company a
customer base of thousands of the world's leading healthcare organizations, we
have unparalleled opportunities for growth by providing them a single source for
end-to-end, HCO-centric solutions that will support the care, financial and
supply chains and revolutionize the way they deliver healthcare. Whether
customers choose one or several of our solutions, the ultimate `product' we will
offer is a set of unmatched solutions and resources that will deliver them
greater cost savings, efficiencies and a competitive advantage. This includes
the potential to seamlessly integrate across the B2B value chain."

Braden Kelly, a member of HEALTHvision's Board of Directors and principal at
General Atlantic Partners, a founding investor of Eclipsys and HEALTHvision,
stated that "This transaction creates e-health's equivalent of the `Dream Team.'
The combination of Neoforma, Eclipsys and HEALTHvision -- along with long-term
exclusive partnerships with Novation, VHA, and UHC -- immediately establishes
the company as the preeminent B2B information exchange for the healthcare
market. We are enthusiastic about the company's massive potential and the
management team in place to execute on its unified vision." General Atlantic
Partners is one of the world's largest private equity investment firms focused
exclusively on Internet and information-technology investments on a global
basis.

MANAGEMENT TEAM

In addition to Wilson and Zollars, the senior management team will include Fred
Ruegsegger, Neoforma.com's chief financial officer, who will retain that
responsibility at the new company. Other members of the new entity's
senior-management team will be comprised of executives from the merged
companies, with details to be announced at a later date. "In addition to the
scope of our solutions, what differentiates us is the wealth of healthcare
professionals on our team," Wilson said. "Unlike many other companies trying to
capitalize on the e-health explosion, our team has broad, hands-on experience
providing healthcare-related services. That enables us to better understand and
anticipate the needs of our customers in an ever-changing environment."
