Delaware corporation and wholly-owned subsidiary of Neoforma ("Merger Sub"), and
Neoforma, and subject to the conditions set forth therein (including approval by
stockholders of Eclipsys and Neoforma), Merger Sub will merge with and into

will cease to exist as a corporation and all of the business, assets,
liabilities and obligations of Merger Sub will be merged into Eclipsys with
Eclipsys remaining as the surviving corporation (the "Surviving Corporation").

         As a result of the Merger, each outstanding share of Eclipsys common
stock, other than shares owned by Merger Sub, Neoforma or any wholly-owned

         In connection with the Merger, Neoforma entered into an Agreement and
Plan of Merger, dated March 30, 2000, by and among Neoforma and HEALTHvision
(the "HEALTHvision Merger Agreement"), pursuant to which HEALTHvision will merge
with and into Eclipsys immediately following the Merger (the "HEALTHvision
Merger"). As a result of the HEALTHvision Merger, each outstanding share of
HEALTHvision Series A preferred stock will be converted into 0.3041825 shares of
Neoforma common stock and four shares of HEALTHvision common stock and each
outstanding share of HEALTHvision Series B preferred stock will be converted
into four shares of HEALTHvision common stock. Also, each outstanding share of
HEALTHvision common stock, other than shares owned by Merger Sub, Neoforma or
any wholly-owned subsidiary of Neoforma, will be converted into the right to
receive 0.444 shares (the "HEALTHvision Exchange Ratio") of Neoforma common
stock, and each outstanding option to purchase HEALTHvision common stock will be
exchanged for an option to purchase shares of Neoforma common stock according to
the HEALTHvision Exchange Ratio, and each outstanding warrant to purchase a
share of HEALTHvision Series B preferred stock will be exchanged for a warrant
to purchase four shares of Neoforma common stock.

         Concurrently with the execution of the Merger Agreement and the
HEALTHvision Merger Agreement, Neoforma entered 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 HEALTHvision Merger Agreement, the "Related Agreements"). Neoforma has filed
with the Securities Exchange Commission copies of each of the Related Agreements

qualified in its entirety by reference to the full text of such exhibits.

         Under the Merger Agreement, consummation of the Merger is conditioned,

several additional conditions, including approval by each company's
stockholders, and the expiration of applicable waiting periods under antitrust
laws and obtaining necessary consents.

         Each of the Stockholders has, by executing a Voting Agreement, agreed
to vote such portion of the aggregate of 21,041,574 shares of Neoforma common
stock (the "Shares") beneficially owned by him or it as described below.

         Pursuant to the Voting Agreement, each of the Stockholders has agreed,
at every Neoforma stockholders meeting and on every action or approval by
written consent in lieu of such meeting, to cause the Shares to be voted (i) in
favor of the issuance of shares of Neoforma common stock in the Merger and the
HEALTHvision Merger and in favor of the issuance of shares of Neoforma common
stock and warrants to purchase Neoforma common stock, and the shares of Neoforma
common stock issuable pursuant to the terms of such warrants pursuant to the
Stock and Warrant Purchase Agreements, and the other actions contemplated by the
Merger Agreement, the HEALTHvision Merger Agreement and the Stock and Warrant
Purchase Agreements and (ii) against 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 Neoforma under the Merger Agreement, the
HEALTHvision Merger Agreement and the Stock and Warrant Agreements or of such
Stockholder under his respective Voting Agreement. Each of the Stockholders may
vote the Shares owned by such Stockholder on all other matters. Each Voting
Agreement terminates upon the earlier to occur of (i) such date and time as the
HEALTHvision Merger shall become effective in accordance with the terms and
provisions of the HEALTHvision Merger Agreement and (ii) such date and time as
the Voting Agreement shall have been terminated pursuant to its terms.

         The purpose of the transactions under the Voting Agreement is to
facilitate the consummation of the transactions contemplated under the Merger
Agreement, the HEALTHvision Merger Agreement and Stock and Warrant Purchase
Agreements.

         (c)      Not applicable.

         (d)      Pursuant to the Merger Agreement, the Board of Directors of
Neoforma will take all actions reasonably necessary such that as soon as
practicable following the consummation of the Merger, (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, Eclipsys' Chairman and Chief Executive Officer, 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,

appointed to VHA, Inc. 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 of the Merger and such person so
elects, following the effective time of the Merger 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.

         (e) - (i)   Not Applicable.

         (j)      Other than described above, neither Eclipsys nor HEALTHvision
currently has any plans or proposals which relate to, or may result in, any of
the matters listed in Items 4(a) - (j) of Schedule 13D (although Eclipsys and
HEALTHvision each reserve the right to develop such plans).

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

         (a) - (b) As a result of the Voting Agreements, Eclipsys and
HEALTHvision may be deemed to be the beneficial owners of 21,041,574 shares of
Neoforma common stock. Such Neoforma common stock constitutes approximately
32.5% of the issued and outstanding shares of Neoforma common stock based on the
number of shares of Neoforma common stock outstanding as of March 28, 2000 (as
represented by Neoforma in the Merger Agreement discussed in Items 3 and 4).
Eclipsys and HEALTHvision may be deemed to have the shared power to vote the
Shares with respect to those matters described above. However, each of Eclipsys
and HEALTHvision (i) is not entitled to any rights as a stockholder of Neoforma
as to the Shares other than as described above and (ii) disclaims any beneficial
ownership of the shares of Neoforma common stock that are covered by the Voting
Agreements.

         (c)      To the knowledge of Eclipsys and HEALTHvision, no transactions
in the class of securities reported have been effected during the past sixty
days by any person named pursuant to Item 2.

         (d)      To the knowledge of Eclipsys and HEALTHvision, no other person
has the right to receive or the power to direct the receipt of dividends from,
or the proceeds from the sale of, the securities of Neoforma.

         (e)      Not Applicable.

                          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").

                                    RECITALS

     A. The respective Boards of Directors of Parent, Merger Sub and Company
have approved this Agreement, and declared advisable the merger of Merger Sub
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
qualify as a "reorganization" pursuant to the provisions of Section 368 of the
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").

     C. Concurrently with the execution of this Agreement, and as a condition
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
and inducement to Company's willingness to enter into this Agreement, certain
stockholders of Parent are entering into Voting Agreements with Company and
HEALTHvision, Inc., a Delaware corporation ("HEALTHVISION") in the form of
Exhibit B (the "PARENT VOTING AGREEMENTS").

     E. Concurrently with the execution of this Agreement, Parent is entering
into an Agreement and Plan of Merger (the "HEALTHVISION MERGER AGREEMENT")
between Parent and Healthvision, an Outsourcing and Operating Agreement (the
"NOVATION OPERATING AGREEMENT") among Parent, 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 Parent and
VHA, and Parent 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 Healthvision Merger Agreement, the
"RELATED AGREEMENTS"), copies of each of which and all related documents are
attached to the Parent Disclosure Letter (as defined in the introduction to
Article III).

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

                                   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,
Merger Sub shall be merged with and into Company, the separate corporate
existence of Merger Sub shall cease, and Company 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 a
certificate of merger, in such appropriate form as determined by the parties,
with the Secretary of State of the State of Delaware in accordance with the
relevant provisions of Delaware Law (the "CERTIFICATE OF MERGER") (the time of
such filing (or such later time as may be agreed in writing by Company and
Parent and specified in the Certificate of Merger) being the "EFFECTIVE TIME")
as soon as practicable 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 Company and
Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities
and duties of Company and Merger Sub shall become the debts, liabilities and
duties of the Surviving Corporation.

     1.4 Certificate of Incorporation; Bylaws.

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

Certificate of Incorporation of the Surviving Corporation until thereafter
amended.

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

Corporation shall be the directors of Merger Sub 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 Merger Sub 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, 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

     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

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.

any of its subsidiaries or its or any of their respective assets are bound or
affected, except, in the case of clauses (ii) and (iii), for such conflicts,

any of Company's or any of its subsidiaries' agreements, 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,

ACT"), and the securities or antitrust laws of any foreign country, and (iv)

released or stored on, under or about such properties and facilities or
transported to or from such properties and facilities any Hazardous Materials

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.

Parent from terminating or amending any International Employee Plan at any time
for any reason.

owned its properties or leased, owned or operated any facilities, there have
been no disposals, releases or threatened releases of Hazardous Materials (as

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.

         (a) Promptly after the date hereof, Company will take all action
necessary in accordance with the Delaware Law and its Certificate of
Incorporation and Bylaws to convene the Company 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 Parent adjourns or postpones the Parent Stockholders' Meeting,
Company may adjourn or postpone the Company Stockholders' Meeting in order that
they be held on the same day), for the purpose of voting upon approval and
adoption of this Agreement and approval of the Merger. Subject to Section
5.2(c), Company will use its commercially reasonable efforts to solicit from its
stockholders proxies in favor of the adoption and approval of this Agreement and
the approval of the Merger 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, Company may adjourn or
postpone the Company Stockholders' Meeting to the extent necessary to ensure
that any necessary supplement or amendment to the Proxy Statement/Prospectus is
provided to Company's stockholders in advance of a vote on the Merger and this
Agreement or, if as of the time for which Company Stockholders' Meeting is
originally scheduled (as set forth in the Proxy Statement/Prospectus) there are
insufficient shares of Company Common Stock represented (either in person or by
proxy) to constitute a quorum necessary to conduct the business of the Company
Stockholders' Meeting. Company shall ensure that the Company Stockholders'
Meeting is called, noticed, convened, held and conducted, and that all proxies
solicited by the Company in connection with the Company 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. Company's obligation to call, give notice of,
convene and hold the Company Stockholders' Meeting in accordance with this
Section 5.2(a) shall not be limited to or otherwise affected by the
commencement, disclosure, announcement or submission to Company of any
Acquisition Proposal or Superior Offer, or by any withdrawal, amendment or
modification of the recommendation of the Board of Directors of Company with
respect to this Agreement or the Merger.

         (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.

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'

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

directly or indirectly, (i) solicit, initiate, encourage or induce the making,
submission or announcement of any Acquisition Proposal (as hereinafter defined),

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

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

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%

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-

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

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

(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

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

     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

         (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

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

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

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.

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.

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

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-

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
breaches of this Agreement and to enforce specifically the terms and provisions
hereof in any court of the United States or any state having jurisdiction, this
being in addition to any other remedy to which they are entitled at law or in
equity.

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.

represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

     8.10 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.

     8.11 Waiver Of Jury Trial. EACH OF PARENT, COMPANY AND MERGER SUB HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,

                                      -67-

                            COMPANY VOTING AGREEMENT


     This COMPANY VOTING AGREEMENT (the "AGREEMENT") is made and entered into as
of March 30, 2000, between Neoforma.com, Inc., a Delaware corporation
("PARENT"), and the undersigned stockholder ("Stockholder") of Eclipsys

     A. Concurrently with the execution of this Agreement, Parent, Company and
NeoIII Acquisition Corp., a Delaware corporation and a wholly-owned first-tier
subsidiary of Parent ("MERGER SUB"), are entering into an Agreement and Plan of
Merger (the "MERGER AGREEMENT") which provides for the merger of Merger Sub with
and into Company (the "MERGER"). Pursuant to the Merger, shares of capital stock
of Company will be converted into shares of Parent Common Stock on the basis
described in the Merger Agreement. Capitalized terms used but not defined herein
shall have the meanings set forth in the Merger Agreement.

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

     C. As a material inducement to enter into the Merger Agreement, Parent
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 Company
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

the meeting of the stockholders of Company 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 Company with respect to the matters referred to
in Section 1.2. Stockholder agrees that any shares of capital stock of Company

after the execution of this Agreement and prior to the date of


<PAGE>   75

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:

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
any provision contained in this Section 1.2.



                                       2
<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
          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 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
Agreement, Stockholder agrees to deliver to Parent a proxy in the form attached
hereto as Exhibit I (the "PROXY"), which shall be irrevocable to the extent set
forth therein, with respect to the Shares.


     2. REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER

         (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.

         (b) Stockholder has the requisite power and authority to enter into
this Agreement and to consummate the transactions contemplated by this
Agreement. The execution and delivery of this Agreement by such Stockholder and
the consummation by such Stockholder of


                                       3
<PAGE>   77

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.

     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 Merger Agreement shall have been validly terminated pursuant to Article VII
thereof. Notwithstanding any other provision hereof, this Agreement shall
terminate in the event that the Merger Agreement is modified in a manner that is
materially adverse to Stockholder without Stockholder's consent.

contract or agreement that requires Stockholder to Transfer Subject Securities

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

person signing this Agreement has full power and authority to enter into and
perform such Agreement.

     3. TERMINATION

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

                                    RECITALS

              A.     Concurrently with the execution of this Agreement, Parent,
Eclipsys and NeoIII Acquisition Corp., a Delaware corporation and a wholly-owned
first-tier subsidiary of Parent ("MERGER SUB"), are entering into an Agreement
and Plan of Merger (the "ECLIPSYS MERGER AGREEMENT") which provides for the

set forth in the Eclipsys Merger Agreement.

              B.     Concurrently with the execution of this Agreement, Parent
and Healthvision are entering into an Agreement and Plan of Merger (the
"HEALTHVISION MERGER AGREEMENT") which provides for the merger of Healthvision
with and into Eclipsys (the "HEALTHVISION MERGER"). Pursuant to the Healthvision
Merger, shares of capital stock of Healthvision will be converted into shares of
Parent Common Stock on the basis described in the Healthvision Merger Agreement.

              C.     Concurrently with the execution of this Agreement, Parent
and VHA, Inc., a Delaware corporation ("VHA"), and Parent and University
Healthsystem Consortium Services Corporation, an Illinois not-for-profit
corporation ("UHC") are entering into respective Common Stock and Warrant
Agreements pursuant to which Parent will issue to VHA and UHC, respectively,
shares of Parent Stock and Warrants to purchase Parent Common Stock (the "STOCK
AND WARRANT AGREEMENT"), in partial consideration for such parties entry into
and continued performance under certain commercial arrangements among such
parties, Parent and others. The Eclipsys Merger, the Healthvision Merger and the
security issuances contemplated by the Stock and Warrant Agreement,
collectively, the "TRANSACTIONS").

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

              E.     As a material inducement for Eclipsys to enter into the
Eclipsys Merger Agreement, Eclipsys desires Stockholder to agree, and as a
material inducement for Healthvision to enter into the Healthvision Merger
Agreement, Healthvision desires Stockholder to agree and Stockholder is willing
to agree, to vote the Shares (as defined below), and such other shares of


<PAGE>   2

capital stock of Parent over which Stockholder has voting power, so as to
facilitate consummation of the Transactions.

              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 Parent 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 Parent 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 Parent with respect to the matters referred to in
Section 1.2. Stockholder agrees that any shares of capital stock of Parent 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) all securities of Parent (including all shares of Parent Common
Stock and all options, warrants and other rights to acquire shares of Parent
Common Stock beneficially owned by Stockholder as of the date of this Agreement;
and (ii) all additional securities of Parent (including all additional shares of
Parent Common Stock and all additional options, warrants and other rights to
acquire shares of Parent 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 Parent are asked to vote upon the issuance
of shares of Parent Common Stock in the Transactions.

                     (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 Healthvision Merger
shall become effective in accordance with the terms and provisions of the
Healthvision Merger Agreement (the "EFFECTIVE TIME") and (ii)

                                       2
<PAGE>   3

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 Parent, however called, or in connection with any written
consent of the stockholders of Parent, 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 issuance of shares of Parent Common Stock
       in the Eclipsys Merger and in the Healthvision Merger, and in favor of
       the issuance of shares of Parent Common Stock and Warrants to purchase
       Parent Common Stock, and the shares of Parent Common Stock issuable
       pursuant to the terms of such Warrants pursuant to the Stock and 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 in a breach in any respect of any covenant, representation or
       warranty 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.

              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:

                     (i)    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

                                       3
<PAGE>   4

(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 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 Parent Common Stock or any securities convertible into or exchangeable or
exercisable for Parent 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 Parent Common Stock,
whether any such swap or transaction is to be settled by delivery of Parent
Common Stock or other securities, in cash or otherwise. The foregoing sentence
shall not apply to (a) transactions relating to Parent Common Stock acquired by
Stockholder in open market transactions, (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.

       2.     REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER

              (a)    Stockholder is the record and beneficial owner of, or
Stockholder 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 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 Parent and has no other interest in or voting
rights with respect to any securities of Parent.

              (b)    Stockholder has the requisite power and authority to enter
into this Agreement and to consummate the transactions contemplated by this
Agreement. The execution and delivery of this Agreement by such Stockholder and
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

                                       4
<PAGE>   5

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.

       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 this Agreement is held by a court of competent jurisdiction to be
invalid, void or unenforceable, then the remainder of the terms, provisions,
covenants and restrictions of this Agreement shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

              4.2    Binding Effect and Assignment. This Agreement and all of
the 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 rights, interests or obligations of the parties hereto may be assigned by
either 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.

              4.4    Specific Performance; Injunctive Relief. The parties hereto
acknowledge that Eclipsys and/or Healthvision will be irreparably harmed and
that there will be no adequate remedy at law for a violation of any of the
covenants or agreements of Stockholder set forth herein. Therefore, it is agreed
that, in addition to any other remedies that may be available to Eclipsys and/or
Healthvision upon any such violation, Eclipsys and/or Healthvision shall have
the right to enforce such covenants and agreements by specific performance,
injunctive relief or by any other means available to Eclipsys and/or
Healthvision at law or in equity.

                          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.

              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.

     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 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
Restricted Stock, together with the number of shares and the vesting schedule of
Healthvision Restricted Stock held by each, is set forth in Part 1.9 of the
Healthvision Disclosure Letter.

     1.10 Tax 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

                                      -8-
<PAGE>   13

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 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
                 REPRESENTATIONS AND WARRANTIES OF HEALTHVISION

     As of the date of this Agreement and as of the Closing Date, Healthvision
represents and warrants to Neoforma, subject to the exceptions specifically
disclosed in writing in the disclosure letter and referencing a specific

     2.1 Organization; Subsidiaries.

         (a) Healthvision 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 (as
defined in Section 8.3) on Healthvision.

         (b) Other than the entities identified in Part 2.1 of the Healthvision
Disclosure Letter, neither Healthvision nor any of the other corporations
identified in Part 2.1 of the Healthvision Disclosure Letter owns any capital
stock of, or any equity interest of any nature in, any corporation, partnership,
joint venture arrangement or other business entity, except for passive
investments in equity interests of public companies as part of the cash
management program of Healthvision. Neither Healthvision nor any of its
subsidiaries is obligated to make any material future investment in or capital
contribution to any other entity. Part 2.1 of the Healthvision Disclosure Letter
indicates the jurisdiction of organization of each entity listed therein and
Healthvision's direct or indirect equity interest therein.

         (c) Healthvision has delivered or made available to Neoforma a true and
correct copy of the Certificate of Incorporation (including any Certificates of
Designation) and Bylaws of Healthvision and similar governing instruments of
each of its subsidiaries, each as

                                      -9-
<PAGE>   14

amended to date (collectively, the "HEALTHVISION CHARTER DOCUMENTS"), and each
such instrument is in full force and effect. Neither Healthvision nor any of its
subsidiaries is in violation of any of the provisions of Healthvision Charter

consisting of 4,028,000 authorized shares of Series A Stock, 2,205,000 of which

subject to any right of rescission. A list of all holders of Healthvision Stock,
and the number of shares held by each, in each case as of the date hereof, is

Healthvision Common Stock are subject to issuance pursuant to outstanding
Healthvision Options for an aggregate exercise price of $7,405,531. Of the
4,460,050 total shares, 500,000 Healthvision Options were granted since March
14, 2000 to persons who have agreed in writing to waive acceleration of such
Healthvision Options and any other Healthvision Options, resulting in a total of
1,056,650 Healthvision Options which will not accelerate, upon consummation of
the Merger and the other transactions contemplated by the Related Agreements.

evidencing Healthvision Options. There are no options outstanding to purchase
shares of Healthvision

                                      -10-

Common Stock other than pursuant to 1999 Plan. All shares of Healthvision Common

Healthvision Options, and all outstanding shares of capital stock of each
subsidiary of Healthvision have been issued and granted in material compliance
with (i) all applicable securities laws and other applicable material Legal

Section 2.2 or Part 2.2 or Part 2.3 of the Healthvision Disclosure Letter, there
are no equity securities, partnership interests or similar ownership interests
of any class of Healthvision equity security, or any securities exchangeable or
convertible into or exercisable for such equity securities, partnership

preemptive right, community property interest or restriction of any nature
(including any restriction on the voting of any security, any restriction on the

<PAGE>   16

it is bound with respect to any equity security of any class of Healthvision or
with respect to any equity security, partnership interest or similar ownership
interest of any class of any of its subsidiaries.

     2.4 Authority; Non-Contravention.

         (a) Healthvision has all requisite corporate power and authority to
enter into this Agreement and the Agreement of Merger and to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the Agreement of Merger and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of Healthvision, subject only to the approval and
adoption of this Agreement and the Agreement of Merger and the approval of the
Merger by Healthvision's stockholders (the "HEALTHVISION STOCKHOLDER Approvals")
and the filing of the Agreement of Merger pursuant to Delaware Law. The
affirmative vote of the holders of a majority of the outstanding shares of
Healthvision Common Stock and Healthvision Preferred Stock (on an as converted
basis) voting together as a single class is sufficient for Healthvision's
stockholders to approve and adopt this Agreement and the Agreement of Merger and
approve the Merger, and no other approval of any holder of any securities of
Healthvision is required in connection with the consummation of the transactions
contemplated hereby. This Agreement and the Agreement of Merger have been duly
executed and delivered by Healthvision and, assuming the due execution and
delivery by Neoforma and Eclipsys, as applicable, constitute valid and binding
obligations of Healthvision, enforceable against Healthvision 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 by Healthvision of this Agreement does
not, and the execution and delivery by Healthvision of the Agreement of Merger
will not, and the performance of this Agreement and the Agreement of Merger by
Healthvision will not (i) conflict with or violate the Healthvision Charter
Documents, (ii) subject to obtaining Healthvision Stockholder Approvals and
compliance with the requirements set forth in Section 2.4(c), conflict with or
violate any law, rule, regulation, order, judgment or decree applicable to
Healthvision or any of its subsidiaries or by which Healthvision or any of its
subsidiaries or 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
Healthvision'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 Healthvision or any of its subsidiaries pursuant to, any
note, bond, mortgage, indenture, agreement, lease, license, permit, franchise or
other instrument or obligation to which Healthvision or any of its subsidiaries
is a party or by which Healthvision or any of its subsidiaries or its or any of
their respective assets 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 Healthvision. Part 2.4(b) of the Healthvision Disclosure
Letter lists all consents, waivers and approvals under any of Healthvision's or
any of its subsidiaries' agreements, 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,

                                      -12-
<PAGE>   17

would have a Material Adverse Effect on Healthvision or would materially and
adversely affect Healthvision's Intellectual Property (as defined below).

         (c) No consent, approval, order or authorization of, or registration,
declaration or filing with any court, administrative agency or commission or
other governmental authority or instrumentality, foreign or domestic
("GOVERNMENTAL ENTITY"), is required to be obtained or made by Healthvision in
connection with the execution and delivery of this Agreement or the consummation
of the Merger, except for (i) the filing of the Agreement of Merger with the
Secretary of State of the State of Delaware and appropriate documents with the
relevant authorities of other states in which Healthvision is qualified to do
business, (ii) the filing of the Proxy Statement/Prospectus (as defined in
Section 2.17) with the Securities and Exchange Commission ("SEC") in accordance
with the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") and
the effectiveness of the Registration Statement (as defined in Section 2.17),
(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 Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (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 Healthvision, Neoforma, or the
Surviving Corporation or would not have a material adverse effect on the ability
of the parties hereto to consummate the Merger.

     2.13 Environmental Matters.

         During the period that Healthvision has leased or owned its properties
or leased, owned or operated any facilities, there have been no disposals,

disposals, releases or threatened releases of Hazardous Materials on, from or
under any of such properties or facilities, which may have occurred prior to

Healthvision. During Healthvision's occupancy of any properties or facilities
owned or leased at any time by Healthvision, neither Healthvision, nor to
Healthvision'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

litigation, proceeding or administrative action brought or threatened against
Healthvision, or any material settlement reached by Healthvision with, any party
or parties alleging the presence, disposal, release or threatened release of any
Hazardous Materials on, from or under any of such properties or facilities.

"THREATENED RELEASE" have the definitions assigned thereto by the Comprehensive

                                      -35-
<PAGE>   40

failure to hold such Neoforma Permits, or be in such compliance, would not,
individually or in the aggregate, have a Material Adverse Effect on Neoforma.

     3.11 Litigation. There are no claims, suits, actions or proceedings pending
or, to the knowledge of Neoforma, threatened against, relating to or affecting
Neoforma 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 Neoforma or on the Surviving Corporation
following the Merger or have a material adverse effect on the ability of the
parties hereto to consummate the Merger.

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.

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

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

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

         (c) Healthvision agrees to use reasonable efforts to: (i) cause each

Healthvision pursuant to any indemnification agreements between Healthvision and
its directors and officers as of the Effective Time (the "INDEMNIFIED PARTIES")

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 Healthvision as in effect on the date hereof, which
provisions will not be amended, repealed or otherwise modified for a period of

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'

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

respective reasonable efforts to cause to be delivered to Neoforma a letter of
Healthvision's and Neoforma's independent accountants, respectively, dated no

situated. Neoforma's benefit arrangements and employee plans shall give full
credit for each participant's continuous period of service with Healthvision

Disclosure Letter) immediately prior to the Effective Time.

three business days, following the date of this Agreement, Healthvision shall
discontinue its efforts to arrange for an initial public offering.

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

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.

assume all options to purchase Healthvision common stock outstanding at the

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,

<PAGE>   78

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
Agreement, Stockholder agrees to deliver to Neoforma a proxy in the form

     2. REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER

         (a) Stockholder is the record and beneficial owner of, or Stockholder
exercises voting power over, the shares of Healthvision capital stock indicated

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

                                IRREVOCABLE PROXY

     The undersigned stockholder (the "STOCKHOLDER") of HEALTHvision, Inc., a
Delaware corporation ("HEALTHVISION"), hereby irrevocably appoints and
constitutes the members of the Board of Directors of Neoforma.com, Inc., a
Delaware corporation ("NEOFORMA"), and each such Board member (collectively the
"PROXYHOLDERS"), the agents, attorneys and proxies of the undersigned, with full
power of substitution and resubstitution, to the full extent of the
undersigned's rights with respect to the shares of capital stock of Healthvision
which are listed below (the "SHARES"), and any and all other shares or
securities issued or issuable in respect thereof on or after the date hereof and
prior to the date this proxy terminates, to vote the Shares as follows: the
agents and proxies named above are empowered at any time prior to termination of
this proxy to exercise all voting and other rights (including, without
limitation, the power to execute and deliver written consents with respect to
the Shares) of the undersigned at every annual, special or adjourned meeting of
Healthvision stockholders, and in every written consent in lieu of such a
meeting, or otherwise, (i) (A) in favor of the approval and adoption of the
Agreement and Plan of Merger (the "PLAN") between Neoforma and Healthvision in
the form entered into on the date hereof and an agreement of merger to be filed
with the Delaware Secretary of State, a form of which is attached as an exhibit
to the Plan, and (B) the approval of the merger of Healthvision with and into
Eclipsys Corporation (the "MERGER"), and (ii) against approval of any proposal
made in opposition to or in competition with consummation of the Merger,
including, without limitation, any Acquisition Proposal (as defined in the Plan)
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 of the Stockholder under the Healthvision Voting
Agreement between Neoforma and Stockholder (the "VOTING AGREEMENT").

     The Proxyholders may not exercise this proxy on any other matter. The
Stockholder may vote the Shares on all such other matters. The proxy granted by
the Stockholder to the Proxyholders hereby is granted as of the date of this
Irrevocable Proxy in order to secure the obligations of the Stockholder set
forth in Section 1 of the Voting Agreement, and is irrevocable and coupled with
an interest in such obligations and in the interests in Healthvision to be
purchased and sold pursuant to the Plan.

     This proxy will terminate upon the termination of the Voting Agreement in
accordance with its terms. Upon the execution hereof, all prior proxies given by
the undersigned with respect to the Shares and any and all other shares or
securities issued or issuable in respect thereof on or after the date hereof are
hereby revoked and no subsequent proxies will be given until such time as this
proxy shall be terminated in accordance with its terms. Any obligation of the
undersigned hereunder shall be binding upon the successors and assigns of the
undersigned. The undersigned stockholder authorizes the Proxyholders to file
this proxy and any substitution or revocation of substitution with the Secretary
of Healthvision and with any Inspector of Elections at any meeting of the
stockholders of Healthvision.

     This proxy is irrevocable and shall survive the insolvency, incapacity,
death or liquidation of the undersigned. Dated: March 30, 2000.
