                      AGREEMENT AND PLAN OF REORGANIZATION

         This Agreement and Plan of Reorganization, entered into on the 28th day
of October, 1998, by and among HealthVISION, Inc., a Delaware corporation having
its principal executive offices at 141 Stony Circle, Suite 150, Santa Rosa,
California 95401 (the "Company"), each of Warburg Pincus Investors, L.P., United
Healthcare Services, Inc., HLM Partners V, L.P. and HLM Partners VII, L.P.
(collectively, the "Principal Stockholders"), each of the other stockholders of
the Company named on SCHEDULE A hereto, (collectively, with the Principal
Stockholders, the "Stockholders"), the holders of outstanding options and
warrants to purchase capital stock of the Company named on SCHEDULE A hereto
(who, with the Stockholders may collectively hereinafter be referred to as the
"Securityholders"), Transition Systems, Inc., a Massachusetts corporation having
its principal executive office at One Boston Place, Boston, Massachusetts 02108
("TSI"), and HV Acquisition Corp., a Delaware corporation and a wholly-owned
subsidiary of TSI ("Acquisition Corp.").

                          W I T N E S S E T H  T H A T

         WHEREAS, the Company is engaged in two principal lines of business
(collectively, the "Business"), namely the development, marketing, licensing and
support of an electronic medical record and clinical data repository system
known as CareVISION, and, acting primarily through its subsidiary HealthVISION
Corporation, the provision of financial and administrative support software to
healthcare institutions in Canada;

         WHEREAS, each of the Stockholders is the record holder of the number of
issued and outstanding shares of capital stock of the Company set forth on
SCHEDULE 2.6 to this Agreement.

         WHEREAS, the parties hereto desire to effect a reorganization in which
Acquisition Corp. will be merged into the Company, as a result of which (a) the
surviving corporation will be a wholly owned subsidiary of TSI, (b) all
outstanding options to purchase capital stock of the Company will become
exercisable and will be exercised in full prior to the merger, and (c) all of
the issued and outstanding capital stock of the Company will be converted into
the right to receive cash in the amounts specified herein.

         NOW, THEREFORE, TSI, Acquisition Corp., the Company and the
Stockholders hereby agree as follows:

         1.       THE MERGER.

         1.1      CERTIFICATE OF MERGER. Subject to and upon the terms and
conditions of this Agreement, and on the basis of the agreements, covenants,
representations and warranties herein contained, at the closing of the
transactions contemplated by this Agreement (the "Closing") authorized officers
of each of the Company and Acquisition Corp. shall execute and file a
Certificate of Merger (the "Certificate of Merger") in accordance with Section
251 of the



<PAGE>   2


Delaware General Corporation Law ("DGCL") in connection with the statutory
merger of Acquisition Corp. with and into the Company (the "Merger").

         1.2      CLOSING DATE. The Closing shall be held within five (5) days
following the satisfaction of each of the conditions set forth in Article 6 and
shall take place at the office of Foley, Hoag & Eliot LLP, Boston,
Massachusetts, at 9 A.M., Eastern Standard Time, or on such other date, or at
such other time and place, as the parties may agree upon in writing. The date on
which the Closing is to be held is herein referred to as the "Closing Date."

         1.3      EFFECTIVE TIME. The Merger shall become effective as of the
time (the "Effective Time") and on such date (the "Effective Date") as the
Certificate of Merger is filed with the Secretary of State of the State of
Delaware. Under this Agreement, shares of the Company issued and outstanding
immediately prior to the Effective Time will be converted into the right to
receive cash, in accordance with Section 1.4.

         1.4      EFFECT ON CAPITAL STOCK. At the Effective Time, by virtue of
the Merger and without any action on the part of any party:

                  1.4.1    All of the 1,000 issued and outstanding shares of
common stock of Acquisition Corp. shall be converted into an aggregate of 1,000
shares of common stock of the Surviving Corporation (as defined in Section 1.6).
Each stock certificate representing shares of common stock of Acquisition Corp.
prior to the Effective Time shall represent an equal number of shares of common
stock of the Surviving Corporation from and after the Effective Time.

                  1.4.2    Each share of the capital stock of the Company issued
and outstanding immediately prior to the Effective Time (the "Determination
Time") shall be converted, subject to the indemnification provisions of Article
7 and to Section 1.4.2(g) below, into the right to receive the consideration set
forth below. Subject to the terms and conditions of this Agreement, as of the
Effective Time, by virtue of the Merger and without any action on the part of
Acquisition Corp., the Company or the holder of any shares of the capital stock
of the Company, the following shall occur:

                           (a)      Each holder of record of a share of seven
         percent (7%) preferred stock, $.01 par value ("Junior Preferred Stock")
         of the Company issued and outstanding at the Determination Time (each a
         "Junior Preferred Holder") shall receive cash in an amount equal to the
         Preference Amount in respect of such share.

                           (b)      For purposes of this Agreement, (i) the
         "Preference Amount" in respect of a share of Junior Preferred Stock
         shall be the sum of $100 plus the amount of all dividends accrued and
         unpaid on such share, at the rate of 7% per annum, from the date of its
         issuance, and (ii) the "TSI Share Value" determined as of any date
         shall be an amount equal to the average of the last sale prices of the
         TSI Common as reported by the Nasdaq National Market on each of the
         twenty (20) trading days preceding such date.





                                        2




<PAGE>   3


                           (c)      Each holder of record of common stock, $.01
         par value, of the Company ("Company Common") issued and outstanding at
         the Determination Time (a "Common Holder") shall receive:

                                    (i)      an amount of cash equal to the
                           product of (A) the number of shares of Company Common
                           held by the Common Holder at the Determination Time
                           multiplied by (B) the Adjusted Company Common Value;
                           and

                                    (ii)     the right to receive his PRO RATA
                           share of the balance of the Escrow Consideration
                           described in Section 1.4.6, after deductions, if any,
                           pursuant to Section 7.4 below.

                           (d)      The "Company Common Value" shall be an
         amount equal to (i) the sum of (A) $25,600,000 minus (B) the sum of (I)
         the aggregate Preference Amount payable in respect of the Junior
         Preferred Stock and (II) the aggregate amount of the Advances referred
         to in Section 6.3(e) below (the "Common Base Amount"), divided by (ii)
         the number of shares of Common Stock (A) issued and outstanding at the
         Determination Time (other than Common Stock held by TSI) and (B)
         issuable upon exercise of options and warrants to purchase Common Stock
         outstanding at the Determination Time (excluding Common Stock issuable
         to TSI upon conversion of the Senior Preferred Stock) (collectively,
         the "Determination Time Shares"). The "Adjusted Company Common Value"
         shall be an amount equal to the Company Common Value, except that for
         purposes of computing such amount, the Common Base Amount shall be
         reduced by the amount of the Escrow Consideration.

                           (e)      The outstanding warrant to purchase Common
         Stock (the "Warrant") will be assumed by TSI as of the Effective Time
         and shall thereafter entitle its holder, upon exercise following the
         Effective Time, to receive that number of shares of TSI Common equal to
         the product of the number of shares of the Company that were issuable
         upon exercise of such Warrant at the Determination Time multiplied by
         the Merger Ratio, rounded up to the nearest whole number of shares of
         TSI Common. For purposes of this Agreement, "Merger Ratio" shall mean
         the quotient of the Company Common Value divided by the TSI Share Value
         determined as of the Effective Time. In addition, following the
         Effective Time, the per share exercise price for the TSI Common
         issuable upon exercise of the Warrant shall be equal to the quotient,
         rounded down to the nearest whole cent, of the exercise price per share
         of the Company at which such Warrant was exercisable at the
         Determination Time divided by the Merger Ratio. Following the Effective
         Time, the Warrant shall continue to have, and be subject to, the same
         terms and conditions as provided in the agreement governing such
         Warrant at the Determination Time, except as set forth in this Section.

                           (f)      At the Effective Time, each outstanding
         option to purchase Company Common will be cancelled by the Board of
         Directors of the Company, pursuant to authority granted by Article X of
         the Company's 1996 Stock Option Plan and the corresponding Article of
         the 1994 Stock Option Plan of HV Holdings, Inc., predecessor





                                        3


<PAGE>   4


         of the Company, as the case may be, and TSI will pay to the holder of
         each such option (each an "Option Holder") in cash an amount equal to
         the excess of (i) the product of the Adjusted Company Common Value
         multiplied by the number of shares of Company Common as to which such
         option is exercisable (without regard to vesting), over (ii) the
         aggregate exercise price payable upon exercise of such option (the
         "Option Cancellation Amount"). Each Option Holder will also be entitled
         to receive his PRO RATA share of the balance of the Escrow
         Consideration, after deductions, if any, pursuant to Section 7.4 below.

                           (g)      As of the Effective Time, each outstanding
         share of Company Common held by TSI, if any, each share of Senior
         Preferred Stock held by TSI, and each share of Company Common, if any,
         held in the treasury of the Company, shall be canceled and retired.

                  1.4.3    In addition, each Common Holder, each Option Holder
and each holder of a Warrant outstanding at the Determination Time (a "Warrant
Holder") (the Common Holders, Option Holders and the Warrant Holder may
collectively hereinafter be referred to as the "Holders") shall be entitled to
receive contingent consideration (the "Contingent Consideration"), payable in
cash, in the amount, if any, determined as follows:

                           (a)      On January 31, 1999 (the "First Earn-Out
         Date") each Holder shall receive, in respect of each share of Company
         Common held by such Holder or in respect of which the option or Warrant
         held by such Holder was exercisable at the Determination Time (without
         regard to vesting), an amount, if any, determined by dividing (i) the
         First Earn-Out Amount by (ii) the Determination Time Shares.

                           (b)      On July 31, 1999 (the "Second Earn-Out
         Date") each Holder shall receive, in respect of each share of Company
         Common held by such Holder or in respect of which the option or Warrant
         held by such Holder was exercisable at the Determination Date (without
         regard to vesting), an amount determined by dividing (i) the Second
         Earn-Out Amount by (ii) the Determination Time Shares.

                           (c)      On or before each of the First Earn-Out Date
         and the Second Earn-Out Date, TSI will prepare and deliver to each
         Holder a report (each an "Earn-Out Statement") setting forth for the
         periods set forth below (the "First Earn-Out Period" and "Second
         Earn-Out Period," respectively) the following amounts: (i) the amount
         of Bookings for the Company's CareVISION product ("CareVISION"), and
         (ii) the Earn- Out Amount, calculated as hereinafter set forth:

- --------------------------------------------------------------------------------
    First Earn-Out Period               Three months ending December 31, 1998
- --------------------------------------------------------------------------------
    Second Earn-Out Period              Nine months ending June 30, 1999
- --------------------------------------------------------------------------------



                  (d) For purposes of this Section 1.4.3, "Bookings" shall mean
         the value of each contract for the license, implementation or
         maintenance of version

         3.12 or version 3.2 of CareVISION, entered into with a customer that is
         currently in the Company's pipeline and that is listed on SCHEDULE
         1.4.3(D) (a "Qualified Account"), that was executed and became binding
         on the parties thereto during the specified period (but excluding
         renewals or extensions of contracts that were the subject of binding
         commitments in effect prior to August 31, 1998); provided that:

                                    (i)      for the First Earn-Out Period,
                                             Bookings shall exclude the value of
                                             maintenance contracts executed or
                                             renewed during such period; and

                                    (ii)     for both the First Earn-Out Period
                                             and the Second Earn-Out Period,
                                             Bookings shall exclude 50% of the
                                             value of any contract with the
                                             University of California at Davis
                                             Medical Center executed during such
                                             period.

Bookings attributable to the sale or license of TSI of its "Transition IV"
product ("T-IV") shall not be deemed to constitute "Bookings" for purposes of
this Agreement, whether or not T-IV includes some or all of the functionality of
CareVISION.

                           (e)      The Earn-out Amount for the First Earn-Out
         Period shall be $3,750,000; provided, that if the Bookings for the
         First Earn-Out Period, determined as set forth above, are less than the

and, to the Company's knowledge, no event has occurred that, with or without
notice or the lapse of time, would entitle any other party thereto to cancel,
terminate or rescind any of them. No customer or group of customers whose
purchases of goods or services accounted for more than 5% of the consolidated
gross revenues of the Company for 1997 or the eight-month period ended August
31, 1998 has notified the Company or any Subsidiary, whether in writing or
orally, of its intention to terminate, cancel or effect any other material
adverse change in its business relationship with the Company or such Subsidiary.

conducted and as proposed to be conducted, without any known conflict with or
known infringement of the rights of others. Set forth on SCHEDULE 2.14 hereof is

that are the subject of registration or other proceedings with the United States
Patent and Trademark Office or any other agency of federal or state government
or of any foreign jurisdiction, appropriate identifying information (e.g.,
registration or patent numbers, dates of pending applications, etc.) as to the
status of such registration or proceeding. Neither the Company nor any
Subsidiary is bound by or a party to any option, license or agreement of any
kind with respect to Intellectual Property Rights of the Company or such
Subsidiary, or of any other person or entity, the existence, breach or
termination of which would materially impair the business of the Company or the
Subsidiaries as now conducted or as proposed to be conducted and that is not
identified on SCHEDULE 2.14.

Neither the Company nor any Subsidiary has received any written communication
alleging that it has violated, or by conducting its business as currently
proposed would violate, any Intellectual Property Right of any other person or
entity. The Company is not aware that any of its or any Subsidiary's employees
or consultants is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of such employee's or consultant's best efforts to promote the interests
of the Company or such Subsidiary or that would conflict with the Business as
proposed to be conducted. Neither the execution nor the delivery of this
Agreement, nor the carrying on of the business of the Company or any Subsidiary
by its employees, nor the conduct of the Business as currently proposed, will
conflict with or result in a breach of the terms, conditions or provisions of,
or, with or without notice or the lapse of time, constitute a default under, any
contract, covenant or instrument under which any of such employees or
consultants is now obligated and of which the Company has knowledge.

Subsidiary, or any of the employees, officers, directors, consultants or agents
of any of them, and relating to or arising out of the existence, operations or
activities of the Company, any of the Subsidiaries, nor is there any reasonable
basis therefor.

         2.17     COMPLIANCE WITH OTHER LAWS.

         are now in compliance, in all material respects, with all laws, rules,
         regulations, ordinances, decrees, judgments and orders applicable to
         the business and properties of any of them, including, without

         the part of the Company or any Subsidiary;

                  (b)      All employees currently employed by the Company or
         any Subsidiary in the United States who are engaged in the Business are
         authorized for such employment in the United States in accordance with
         the Immigration and Naturalization Act, as amended, and regulations

         Naturalization Service regulations a properly completed Form I-9 for
         each such employee.

liability, and workers' compensation insurance coverages (collectively, the
"Coverage"). Attached as SCHEDULE 2.20 is a summary of all such policies and the
Coverage afforded thereby. The Coverage is provided by insurance companies that
are believed by the Company to be responsible and includes insurance such risks
and in such amounts as are believed by the Company to be reasonable and prudent
for a similarly situated corporation engaged in the Company's and the
Subsidiaries' business. The Company and its Subsidiaries have not incurred any
material uninsured loss or casualty, nor is the Company or any Securityholder
aware of any circumstance or occurrence that could result in a material
uninsured loss or casualty for the Company or any Subsidiary. Neither the
Company nor any Subsidiary has made any intentional misrepresentation of, or
intentionally omitted to disclose, any material fact to any of its insurers that
might justify denial by such insurer of any of the Coverage.

Subsidiary is in violation of any term of its charter document or by-laws.
Neither the Company nor any Subsidiary is in violation in any material respect

actually incurred. Except as set forth on SCHEDULE 2.22, none of said officers,
directors or shareholders, or any members of their immediate families, are
indebted to the Company or any Subsidiary or have any direct or indirect
ownership interest in any firm or business entity which is affiliated with or
with which the Company or any Subsidiary has a business relationship, or any
firm or corporation which competes with the Company or any Subsidiary; provided,
that ownership of 1% or less of the outstanding voting securities of a publicly
traded corporation shall not constitute such a direct or indirect interest. No
officer, director or shareholder, or any member of his immediate family, is,
directly or indirectly, interested in any material contract with the Company or
any Subsidiary. Neither the Company nor any Subsidiary is a guarantor or
indemnitor of any indebtedness of any other person, firm or corporation.

         2.23     PENSION AND BENEFIT PLANS.

                  (a)      The Company has heretofore furnished to TSI copies

         description of, each pension, retirement, profit sharing, deferred
         compensation, stock option, bonus or other plan or other employee
         benefit plan program, arrangement, agreement or understanding, or
         medical, vision, dental or health plan, or life insurance plan
         (collectively, the "Plans") to which the Company or any Subsidiary is
         required to contribute, or which the Company or any Subsidiary
         sponsors;




                                       16
<PAGE>   17

                  (b)      SCHEDULE 2.23 correctly identifies each Plan that is
         an "employee benefit plan" ("ERISA Plan") as defined in Section 3(3) of
         the Employee Retirement Income Security Act of 1974, as amended
         ("ERISA"), and categorizes each ERISA Plan as an "employee welfare
         benefit plan" ("ERISA Welfare Plan") as defined in Section 3(1) of
         ERISA or an "employee pension benefit plan" ("ERISA Pension Plan") as
         defined in Section 3(2) of ERISA. Neither the Company nor any
         Subsidiary is, or ever has been, obligated to make contributions to any
         "multi-employer plan" as defined in Section 3(37) or 4001(a)(3) of
         ERISA. Neither the Company nor any Subsidiary maintains or contributes
         to, nor has any one them maintained or contributed to, any ERISA
         Pension Plan that is a "defined benefit" plan subject to Title IV of
         ERISA. Each ERISA Pension Plan that is intended to be a "qualified
         plan" within the meaning of Section 401(a) of the Code has been
         determined by the Internal Revenue Service to be so qualified; and to
         the best of the Company's knowledge, no event or circumstance has
         occurred or exists that would adversely affect the qualified status of
         such ERISA Pension Plan.

                  (c)      No "prohibited transaction" within the meaning of
         Section 406 of ERISA or Section 4975 of the Code has occurred with
         respect to any Plan of the Company or any Subsidiary;

                  (d)      None of the ERISA Plans, on its face or as
         administered by the Company or any Subsidiary, fails to comply
         currently, or has failed to comply in the past, in any material
         respect, in form and in operation, with its respective plans of
         benefits and trust agreements or with the provisions of ERISA and the
         Code, the rules and regulations promulgated thereunder, or any other
         applicable federal, state or local law or regulations;

                  (e)      Other than routine claims for benefits, there are no
         actions, suits or claims pending or which could reasonably be expected
         to be asserted, against any Plan, any fiduciary of any Plan or the
         assets of any Plan of the Company or any Subsidiary; and

                  (f)      No ERISA Plan is funded through a "welfare benefit
         fund" within the meaning of Section 419 of the Code, and no benefits
         under any ERISA Plan are provided through a "voluntary employees'
         beneficiary association" within the meaning of Section 501(c)(9) of the
         Code. Neither the Company nor any Subsidiary has any obligation to
         provide medical, health, disability, life insurance, pension,
         retirement or other benefits, under any Plan or otherwise, except to
         its active employees, other than (i) continuation coverage for a
         limited period of time mandated by federal, state or local law, or (ii)
         benefits under any qualified ERISA Pension Plan.

         2.24     TAX EFFECTS OF TRANSACTIONS. Management of the Company has
disclosed to each Securityholder the likely federal and state income tax
consequences of the transactions contemplated hereby and has recommended that
each such Securityholder consent with his or her own tax advisor concerning such

Securityholder, severally and not jointly and as to itself only, hereby

6.1(a), no consent, approval or authorization of, or designation, declaration or

<PAGE>   19

corporation which competes with the Company or any Subsidiary. No Securityholder

         by the stockholders of the Company and Acquisition Corp.

                  (c)      No temporary restraining order, preliminary
         injunction or permanent injunction or other order preventing the
         consummation of the transactions contemplated by this Agreement shall
         have been issued by any federal or state court and remain in effect,
         and no litigation brought by any Governmental Entity seeking the
         issuance of such an order or injunction shall be pending which, in the
         good faith judgment of the Company's or TSI's board of directors, has a
         reasonable probability of resulting in such order, injunction or
         damages. In the event any such order or injunction shall have been
         issued, each party agrees to use its reasonable efforts to have any
         such injunction lifted.

                  (d)      No statute, rule or regulation shall have been
         enacted by any Governmental Entity that makes the consummation of the
         transactions contemplated by this Agreement illegal, prohibits TSI's

         assets of the Company, or compels TSI to dispose of or hold separate
         all or a material portion of the business or assets of the Company, as
         a result of the transactions contemplated by this Agreement, or renders

         Representative and the Escrow Agent shall have entered into the Escrow
         Agreement.

         6.2      CONDITIONS TO OBLIGATIONS OF TSI AND ACQUISITION CORP. The

         and correct as of such date) and (iii) in each case except where the
         failure to be so true and correct would not have a Company Material
         Adverse Effect (other than representations and warranties that are
         already so qualified, which shall be true and correct as written). The
         Company and Securityholder shall have performed in all material
         respects all obligations required to be performed under this Agreement
         prior to the Closing Date by such parties. Since August 31, 1998 there
         shall have been no changes that, in the aggregate, have had or could
         reasonably be expected to have a Company Material Adverse Effect, and
         the Closing, itself, will not cause any default under any material
         contract to which the Company is a party that would have a Company
         Material Adverse Effect. TSI shall have received a certificate signed
         by the chief executive officer and chief financial officer of the
         Company and by each the Stockholders' Representative confirming the
         preceding three sentences.

                  (b)      Authorized officers of the Company shall have

                  (c)      Each Stockholder shall have delivered to TSI,
         simultaneously with the execution of this Agreement, his or her
         irrevocable proxy (each, an "Irrevocable Proxy") in the form of EXHIBIT
         6.2(C) with respect to approval of the Merger by the stockholders of
         the Company.

                  (d)      TSI shall have received an opinion dated as of the
         Closing Date of Dorsey & Whitney LLP, counsel for the Company and the
         Stockholders, in form and substance reasonably satisfactory to TSI and
         its counsel.

                  (e)      Each option to acquire Common Stock outstanding at
         the Determination Time shall have been cancelled by the Board of
         Directors of the Company in the manner specified in Section 1.4.2(f)
         above.

                  (f)      The Company shall have received a letter from each
         person who is an officer or director of the Company immediately prior
         to the Closing Date, to the effect that such person thereby resigns
         from all such offices effective as of the Closing Date.

                  (g)      Each Holder shall have delivered to TSI an affidavit
         complying with the requirements of Code section 1445 and the
         regulations thereunder certifying as to the non-foreign status of such
         Holder, or the Company shall have delivered to TSI certificates
         complying with the requirements of Section 1445 of the Code and the
         regulations thereunder to the effect that the Company and the Related
         Companies are not and have not been U.S. real property holding
         corporations.

         6.3      CONDITIONS TO OBLIGATIONS OF THE COMPANY. The obligations of
the Company to effect the transactions contemplated by this Agreement are
subject to the satisfaction on or prior to the Closing Date of the following
conditions unless waived by the Company:




                                       24
<PAGE>   25


                  (a)      The representations and warranties of TSI and
         Acquisition Corp. set forth in this Agreement shall be true and correct
         as of the date of this Agreement and as if made at and as of the
         Closing Date, except for (i) changes specifically contemplated by this
         Agreement, (ii) those representations and warranties that address
         matters only as of a particular date (which shall remain true and
         correct as of such date) and (iii) in each case except where the
         failure to be so true and correct would not have a TSI Material Adverse
         Effect. TSI and Acquisition Corp. shall have performed in all material
         respects all obligations required to be performed under this Agreement
         prior to the Closing Date by such parties. The Company shall have
         received a certificate signed by the chief executive officer and chief
         financial officer of TSI and Acquisition Corp. confirming the preceding
         three sentences.

                  (b)      Authorized officers of Acquisition Corp. shall have
         executed the Certificate of Merger.

                  (c)      The Company and the Principal Stockholders shall have
         received an opinion dated as of the Closing Date of Foley, Hoag & Eliot
         LLP, counsel to TSI and Acquisition Corp., as to the matters set forth
         in Sections 4.1 and 4.2 above.

                  (d)      The Company shall have repaid in full all outstanding
         principal and unpaid interest with respect to certain advances
         (collectively, the "Advances") evidenced by those certain promissory
         notes in the aggregate original principal amount of $3,252,172
         delivered by the Company to the Principal Stockholders.

         7.       INDEMNIFICATION

         7.1      AGREEMENT TO INDEMNIFY. Subject to the limitations set forth
in Sections 7.4, 7.5 and 7.6 below, the Securityholders hereby agree to, and
each other Holder, by virtue of his receipt of the Merger Consideration
specified in Section 1.4 shall be deemed to have agreed to, jointly and
severally (and without any right of contribution from or indemnification by the
Company) indemnify, defend and hold harmless TSI and the Surviving Corporation
(and their respective affiliates, officers, directors, employees,
representatives and agents) (collectively, the "Indemnified Persons") against
and in respect of any and all claims, costs, losses, expenses, liabilities or
other damages, including interest, penalties and reasonable attorneys' fees and
disbursements (collectively, "Damages") by reason of or otherwise arising out
of:

                  (a)      any breach by the Company of a representation,
         warranty or covenant contained in this Agreement; and

                  (b)      those additional matters set forth on SCHEDULE 7.1(b)
         hereto.

         In addition, each Securityholder agrees, severally but not jointly, to
indemnify, defend and hold harmless the Indemnified Persons against and in
respect of all Damages by reason of or otherwise arising out of any breach by
such Securityholder of a representation, warranty or covenant contained in this
Agreement.



                                       25
<PAGE>   26

         The amounts for which the Indemnified Persons may seek indemnification
under this Article 7 shall extend to, and as used herein the term "Damages"
shall include, reasonable attorneys' fees and disbursements, reasonable
accountants' fees, costs of litigation and other expenses incurred by them in
the defense of any claim asserted against them and any amounts paid in
settlement or compromise of any claim asserted against them to the extent that
the claim asserted is or would have been subject to the indemnification
provisions hereof, subject to the limitations set forth in Section 7.6. The
indemnity under this Article 7 extends only to the net amount of Damages
sustained by the Indemnified Person after deducting therefrom any amount that
such Indemnified Person recovers as proceeds of insurance in respect of such
claim, net of any cost of collection, deductible, retroactive premium
adjustment, reimbursement obligation or other cost directly related to the
insurance claim for such claim.

         7.2      ADDITIONAL INDEMNIFICATION BY SECURITYHOLDERS. In the event
that (a) any holder of outstanding securities of the Company who is not a party
to this Agreement shall object to the Merger and shall (i) duly perfect his
right to appraisal of such securities in accordance with Section 262 of the
Delaware General Corporation Law ("DGCL"), or (ii) initiate an action seeking to
enjoin or prevent the Merger or to challenge its fairness as to him (in each
case, an "Objecting Securityholder"), and (b) as a result of any such appraisal
proceeding or action commenced by an Objecting Securityholder TSI shall incur
any cost, expense, loss or damages (including, without limitation, reasonable
fees and expenses of counsel engaged in connection with such proceeding or
action) or shall be required to pay any amount as additional consideration for
the purchase of the securities held by such Objecting Securityholder, whether by
reason of a final determination by a court of competent jurisdiction in such
proceeding or action, or by reason of any settlement or compromise thereof, or
otherwise, that is in excess of the amount that would have been received by such
Objecting Securityholder if he had been a party to this Agreement and had
received the merger consideration provided for in Sections 1.4.2 and 1.4.3 above
(collectively, the "Merger Consideration") for such securities, then any such
cost, expense, loss, damages or additional consideration shall for purposes of
this paragraph be referred to as an "Excess Acquisition Cost." Each Stockholder,
severally and not jointly, and without regard to the limitations set forth in
Sections 7.4, 7.5 and 7.6 below, agrees to indemnify and hold TSI harmless of
and from any Excess Acquisition Costs. The liability of each indemnifying
Stockholder under this paragraph shall be limited to his PRO RATA share
determined by reference to the amount of the Merger Consideration payable to
such indemnifying Stockholder in relation to the aggregate amount of the Merger
Consideration payable to all such Stockholders of the lesser of (x) the
aggregate Escrow Consideration, and (y) the aggregate Excess Acquisition Costs.
TSI will promptly notify the Stockholders in writing in the event that any
Objecting Securityholder shall initiate any appraisal proceeding or action
subject to indemnification hereunder. Upon receipt by TSI of the written
acknowledgment of each such Stockholder of its indemnity obligations under this
Section and undertaking by such Stockholder to defend such proceeding or action,
the Stockholders shall be entitled to control the defense of such proceeding or
action by counsel of their choosing reasonably satisfactory to TSI; provided,
that no settlement or compromise of any such proceeding or action shall be
entered into without the written consent of the Company and TSI, which consent
shall not unreasonably be withheld.



                                       26
<PAGE>   27

         7.3      APPOINTMENT OF STOCKHOLDERS' REPRESENTATIVE. Each Holder, by
operation of the Merger and by virtue of his receipt of the Merger Consideration
specified in Section 1.4 above, shall be deemed at the Effective Time to have
appointed Warburg Pincus Investors, L.P., HLM Partners V, L.P. and HLM Partners
VII, L.P. and each of them, acting singly, with full power of substitution, the
representatives and attorneys-in-fact of such Holder (the "Stockholders'
Representatives"), with full power and authority in the name of and for and on
behalf of such Holder to:

                  (a)      execute and deliver on behalf of such Holder the
         Escrow Agreement; and

                  (b)      to take any other action on behalf of such Holder
         permitted or required under the Escrow Agreement or this Section 7,
         including, without limitation, the giving and receipt of any notice and
         the settlement or compromise of any claim in respect of which
         indemnification is sought hereunder.

         This power of attorney, and the authority conferred hereby, being
coupled with an interest, are irrevocable and shall not be terminable by any act
or deed of such Holder, by the death or incapacity of such Holder, by operation
of law or otherwise. Notwithstanding the foregoing, this power of attorney shall
terminate in the event that the Closing has not taken place within one hundred
twenty (120) days after the date hereof.

         7.4      ESCROW. To the extent any Indemnified Party may be entitled to
indemnification under Section 7.1 or 7.2, such Indemnified Party shall be
entitled to recover from the Escrow Agent and apply against such Damages or
Excess Acquisition Cost the Escrow Consideration in accordance with the terms of
the Escrow Agreement. In the case of indemnification pursuant to Section 7.1
(but not Section 7.2) above, recovery from the Escrow Agent shall be the sole
remedy available to the Indemnified Party. The amount of any Damages or Excess
Acquisition Cost so recovered shall be deemed to constitute a reduction in the
purchase price payable hereunder.

         7.5      SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Except as
otherwise set forth below, the representations and warranties of the Company and
the Stockholders in this Agreement shall survive the Closing, and any
investigation made by TSI, for a period of one (1) year after the Closing Date
(the "Survival Period"). Notwithstanding the foregoing, the Survival Period for
the representations and warranties of the Company in Section 2.12 shall continue
until the expiration of the statute of limitations for the applicable tax
return. The representations and warranties of TSI and Acquisition Corp. shall
terminate at the Effective Time. The covenants of any party shall survive the
Closing in accordance with their terms.

         7.6      CERTAIN LIMITATIONS. The obligations of the Holders with
respect to indemnification pursuant to Section 7.1 above shall be subject to the
following limitations:

                  (a)      no indemnification shall be required to be made
         hereunder (i) with regard to individual claims for $5,000 or less and
         (ii) unless the aggregate amount of individual claims of greater than
         $5,000 for which indemnity is sought exceeds $100,000, in which case
         indemnification shall be provided to the full extent of such claims;




                                       27
<PAGE>   28

                  (b)      the liability of the Holders for indemnification
         hereunder shall not exceed (i) in the case of any individual claim, an
         amount equal to 80% of the Damages incurred by the Indemnified Parties
         in receipt of such claim, and (ii) in the aggregate, the amount of the
         Escrow Consideration;

                  (c)      no claims for indemnity shall be made after the
         expiration of the applicable Survival Period;

                  (d)      the limitations in Sections 7.6(a) and (b) above
         shall not apply to any claim arising out of (i) breach by a Stockholder
         of a representation or warranty in Section 3.1 or 3.2, (ii) intentional
         or fraudulent misrepresentation by a Securityholder, or (iii) breach of
         a covenant by a Securityholder; and

                  (e)      subject to paragraph (d) above, the parties agree
         that any distribution of property pursuant to the Escrow Agreement to
         satisfy a claim for which indemnification is sought hereunder shall be
         made so as to reduce each Holder's interest in the aggregate Escrow
         Consideration in a PRO RATA manner, based on the Holders' respective
         ownership interests in the Escrow Consideration.

         8.       TERMINATION, AMENDMENT AND WAIVER

         8.1      TERMINATION. This Agreement may be terminated at any time
prior to the Closing:

                  (a)      by the Company if there has been a breach of any
         representation, warranty, covenant or agreement contained in this
         Agreement on the part of TSI or Acquisition Corp. such that the
         condition set forth in Section 6.3(a) would not be satisfied and, if
         such breach is curable, such breach has not been cured within twenty
         days after written notice of such breach, or by TSI if there has been a
         breach of any representation, warranty, covenant or agreement contained
         in this Agreement on the part of the Company or any Stockholder such
         that the condition set forth in Section 6.2(a) would not be satisfied
         and, if such breach is curable, such breach has not been cured within
         twenty days after written notice of such breach;

                  (b)      by the Company or TSI if the Closing shall not have
         been occurred on or before April 30, 1999; provided, however, that the
         rights to terminate this Agreement under this Section 8.1 shall not be
         available to any party whose failure to fulfill an obligation under
         this Agreement has been the cause of the failure of the Merger to occur
         on or before such date;

                (c)      by the Company or TSI if (i) there shall be a final
         nonappealable order of a federal or state court in effect preventing
         consummation of the transactions contemplated by this Agreement or (ii)
         there shall be any action taken, or any statute, rule, regulation or
         order erected, promulgated or issued or deemed applicable to the
         transactions 




                                       28
<PAGE>   29

         contemplated by this Agreement by any Governmental Entity which would
         make consummation of the transactions contemplated by this Agreement
         illegal; and

                  (d)      by the Company or TSI if there shall be any action
         taken, or any statute, rule, regulation or order enacted, promulgated
         or issued or deemed applicable to the transactions contemplated by this
         Agreement by any Governmental Entity that would (i) prohibit TSI's or
         the Company's ownership or operation of all or a material portion of
         the business or assets of the Company or TSI and its subsidiaries taken
         as a whole, or compel TSI or the Company to dispose of or hold separate
         all or a material portion of the business or assets of the Company or
         TSI, as a result of the transactions contemplated by this Agreement or
         (ii) render TSI, the Company or any Stockholder unable to consummate
         the transactions contemplated by this Agreement.

         8.2      EFFECT OF TERMINATION. In the event of termination of this
Agreement by the Company or TSI as provided in Section 8.1, this Agreement shall
forthwith become void and there shall be no liability or obligation on the part
of TSI or the Company or their respective officers or directors or any
Securityholders, except that if such termination is pursuant to Section 8.1(a)
or (b) and the failure of the Closing to occur is the result of any material and
intentionally fraudulent misrepresentation by the other party made herein or an
intentional breach by the other party of any of its material agreements herein,
the terminating party shall be entitled (a) to recover from the breaching party

investigation, preparation and carrying out of the transactions contemplated
hereby and (b) to receive from the breaching party, immediately upon written
demand, a fee (the "Termination Fee") in an amount equal to $5,000,000 less the

         9.       MISCELLANEOUS.

         9.1      PARTIES IN INTEREST. All covenants, agreements,
representations, warranties and undertakings contained in this Agreement by and
on behalf of any of the parties hereto shall bind and inure to the benefit of
the respective successors and assigns of the parties hereto, whether so
expressed or not.

         9.2      ENTIRE AGREEMENT; MODIFICATIONS. This Agreement constitutes
the entire agreement of the parties with respect to the subject matter hereof,
and supersedes all prior agreements, understanding and communications between
the parties, written or oral, with respect to such subject matters, including,
without limitation, that certain Stock Purchase Agreement dated January 29,
1997. Changes in or additions to this Agreement may be made, or compliance with
any term, covenant, agreement, condition or provisions set forth herein may be
omitted or waived (either generally or in a particular instance and either
retroactively or prospectively), only in writing, and only with the written
consent of the Company, Securityholders beneficially owning not less than
two-thirds of the Company's Common Stock (assuming the exercise of all then

waiver effected by the consent of less than all the Securityholders shall be
forthwith sent to any Securityholder who did not consent thereto.

         9.3      GOVERNING LAW. This Agreement shall be deemed a contract made
under seal under the laws of The Commonwealth of Massachusetts, and, together
with the rights, and obligations of the parties hereunder, shall be construed
under and governed by the internal laws of such Commonwealth without regard to
principles of conflicts of laws.

         9.4      ARBITRATION.

                  (a)      Any dispute, controversy or claim arising in
         connection with this Agreement, including any claim for indemnification
         pursuant to Section 7 of this Agreement, shall be settled by expedited
         arbitration by a panel of three arbitrators. The arbitration shall be
         held in Boston, Massachusetts and shall be conducted in accordance with
         the Commercial Arbitration Rules of the American Arbitration
         Association, except that the rules set forth in this Section 9.4 shall
         govern such arbitration to the extent they conflict with the rules of
         the American Arbitration Association.

                  (b)      Upon written notice by a party to any other party of
         a request for arbitration hereunder, TSI and the Stockholders'
         Representative shall each select an arbitrator within thirty days after
         the date of such notice, and the two arbitrators so selected shall use
         their best efforts to select a mutually acceptable arbitrator within
         thirty days after their selection. If the two arbitrators are unable to
         agree upon a third arbitrator within said thirty-day period, the third
         arbitrator shall be selected by the American Arbitration Association
         pursuant to its rules. The arbitration shall be conducted in an
         expeditious manner, the parties using their best efforts to cause the
         arbitration to be completed within sixty days after selection of the
         arbitrator. In the arbitration, there shall be no discovery except as
         the arbitrators shall permit following a determination by the
         arbitrators that the party seeking such discovery has substantial
         demonstrable need. All other procedural matters shall be within the
         discretion of the arbitrators. In the event a party fails to comply
         with the procedures in any arbitration in a manner deemed material by
         the arbitrators, the arbitrators shall fix a reasonable period of time
         for compliance and, if the party does not comply within said period, a
         remedy deemed just by the arbitrators, including an award of default,
         may be imposed.

                  (c)      The determination of the arbitrators by majority vote
         shall be final and binding on the parties. The expense of the
         arbitration and all expenses incurred by the parties with respect
         thereto (including reasonable attorneys' fees and fees of experts)
         shall be borne by the party not prevailing in the arbitration, as
         determined by the arbitrators. Judgment upon the award rendered by the
         arbitrators may be entered in the U.S. District Court for the District
         of Massachusetts sitting in Boston, Massachusetts.

         9.5      NOTICES. All notices, requests, consents and demands shall be
in writing and shall be mailed, first class mail, postage prepaid, if to the
Company or to any Securityholder, at the Company's principal office, and if to
TSI, at its principal office, in each case at the address set

such party in writing to the other parties hereto.

         9.6      COUNTERPARTS. This Agreement may be executed in counterparts,
all of which together shall constitute one and the same instrument.

         9.7      EFFECT OF HEADINGS. The section and paragraph headings herein
are for convenience only and shall not affect the construction hereof.

         9.8      GENDER, ETC. Where the context so requires, any gender used in

genders, and the singular number shall be deemed to include the plural, and vice
versa.

                                IRREVOCABLE PROXY


         The undersigned stockholder (the "Stockholder") of HealthVISION, Inc.,
a Delaware corporation ("HealthVISION"), hereby irrevocably appoints Robert F.
Raco, Paula J. Malzone and Christine Shapleigh, and each of them, as the sole
and exclusive attorneys and proxies of the Stockholder, with full power of
substitution and re-substitution, to the full extent of the Stockholder's rights
with respect to the voting of all issued and outstanding shares of capital stock
of HealthVISION now or hereafter owned of record or beneficially (over which
beneficially-owned shares the Stockholder exercises voting power) by the
Stockholder (the "Shares") on the matters described below (and on no other
matter), until such time as the Agreement and Plan of Reorganization dated as of
October 28, 1998 (the "Reorganization Agreement") among Transition Systems, Inc.
("TSI"), HV Acquisition Corp., HealthVISION and certain other parties shall be
terminated in accordance with its terms or the Merger (as defined in the
Reorganization Agreement) becomes effective. Upon the execution hereof, all
prior proxies given by the Stockholder 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.

         This proxy is irrevocable, is granted pursuant to the Reorganization
Agreement and is granted in consideration of TSI entering into the
Reorganization Agreement. The attorneys and proxies named above will be
empowered at any time prior to the earlier of termination of the Reorganization
Agreement and the date on which the Merger becomes effective to exercise all
voting rights (including the power to execute and deliver written consents with
respect to the Shares) of the Stockholder at every annual, special or adjourned
meeting of HealthVISION's stockholders, and in every written consent in lieu of
such a meeting, or otherwise, to vote the Shares in favor of the approval of the
Reorganization Agreement and the Merger.

         The attorneys and proxies named above may only exercise this proxy to
vote the Shares subject hereto (i) prior to the earlier of termination of the
Reorganization Agreement and the time and date at which the Merger becomes
effective, and (ii) at any annual, special or adjourned meeting of the
stockholders of HealthVISION or in connection with the solicitation of any
written consent in lieu of such meeting, at which meeting or in which consent
approval by the stockholders of HealthVISION of the Reorganization Agreement and
the Merger is sought. At any such meeting or in connection with any such consent
solicitation, the attorneys and proxies named above will vote the Shares in
favor of approval of the Reorganization Agreement and the Merger. The
Stockholder may vote the Shares in his sole discretion on all other matters.

         Any obligation of the Stockholder hereunder shall be binding upon the
successors and assigns of the Stockholder.

Exercise Acquisition Corp., a Massachusetts corporation and a direct,
wholly-owned subsidiary of Eclipsys ("Sub"), and Transition Systems, Inc., a
Massachusetts corporation ("TSI").

         WHEREAS, the Boards of Directors of Eclipsys and TSI deem it advisable
and in the best interests of each corporation and its respective stockholders
that Eclipsys and TSI combine in order to advance the long-term business
interests of Eclipsys and TSI;

         WHEREAS, the combination of Eclipsys and TSI shall be effected by the
terms of this Agreement through a merger in which the stockholders of TSI will
become stockholders of Eclipsys (the "Merger");

         WHEREAS, for Federal income tax purposes, it is intended that the
Merger shall qualify as a reorganization within the meaning of Section 368(a) of
the Internal Revenue Code of 1986, as amended (the "Code"); and

         WHEREAS, for accounting purposes, it is intended that the Merger shall
be accounted for as a pooling of interests;

         NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth below, the
parties agree as follows:

                                    ARTICLE I

                                      - 1 -

         Section 1.02 CLOSING. The closing of the Merger (the "Closing") will
take place at 10:00 a.m., Eastern Time, on a date to be specified by Eclipsys
and TSI, which shall be no later than the second business day after satisfaction
of the latest to occur of the conditions set forth in Sections 7.01, 7.02 and
7.03 (the "Closing Date"), at the offices of Hale and Dorr LLP, 60 State Street,
Boston, Massachusetts, unless another date, place or time is agreed to in
writing by Eclipsys and TSI.

         Section 1.03 EFFECTS OF THE MERGER. At the Effective Time (i) the
separate existence of Sub shall cease and Sub shall be merged with and into TSI
(Sub and TSI are sometimes referred to below as the "Constituent Corporations"
and TSI is sometimes referred to herein as the "Surviving Corporation"), (ii)
the Articles of Organization of Sub immediately prior to the Effective Time
shall be the Articles of Organization of the Surviving Corporation, except that
the name of the corporation set forth therein shall be changed to the name of
TSI, (iii) the Bylaws of the Sub as in effect immediately prior to the Effective
Time shall be the Bylaws of the Surviving Corporation, except that the name of
the corporation set forth therein shall be changed to the name of TSI, and (iv)
the purpose of the Surviving Corporation shall be as set forth in Article II of
the Articles of Organization of Sub immediately prior to the Effective Date.

         Section 1.04 DIRECTORS OF ECLIPSYS.

         (a) Prior to the Effective Time, Eclipsys shall (i) increase the number
of the members of the Board of Directors of Eclipsys to nine and (ii) take such
action as may be necessary such that Robert F. Raco and Patrick T. Hackett (the
"TSI Designees") shall have been elected to the Board of Directors of Eclipsys
as of the Effective Time, Mr. Raco to be assigned to Class II and Mr. Hackett to
be assigned to Class III on the Eclipsys Board of Directors. If, prior to the
Effective Time, any of the TSI Designees shall decline or be unable to serve as
a TSI Designee, TSI shall designate another person to serve in such person's
stead, which person shall be reasonably acceptable to Eclipsys.

         (b) The directors of Eclipsys elected pursuant to Section 1.04(a) shall
hold their positions until their resignation or removal or the election or
appointment of their successors in the manner provided by Eclipsys' charter

                                   ARTICLE II

                            CONVERSION OF SECURITIES

         Section 2.01 CONVERSION OF CAPITAL STOCK. As of the Effective Time, by
virtue of the Merger and without any action on the part of the holder of any
shares of TSI Common Stock or capital stock of Sub:

         (a) CAPITAL STOCK OF SUB. Each issued and outstanding share of the
capital stock of Sub shall be converted into and become one fully paid and
nonassessable share of Common Stock of the Surviving Corporation.

         (b) CANCELLATION OF TREASURY STOCK AND ECLIPSYS-OWNED STOCK. All shares
of Common Stock of TSI, $.01 par value ("TSI Voting Common Stock"), and all
shares of NonVoting Common Stock of TSI, $.01 par value ("TSI Non-Voting Common
Stock" and, together with the TSI Voting Common Stock, "TSI Common Stock"), that
are owned by TSI as treasury stock and any shares of TSI Common Stock owned by
Eclipsys, Sub or any other wholly-owned Subsidiary (as defined in Section 3.01)
of Eclipsys shall be cancelled and retired and shall cease to exist and no stock
of Eclipsys or other consideration shall be delivered in exchange therefor. All
shares of Common Stock, $.01 par value per share, of Eclipsys ("Eclipsys Voting
Common Stock") owned by TSI shall be unaffected by the Merger.

         (c) EXCHANGE RATIO FOR TSI COMMON STOCK. Subject to Section 2.02, each
issued and outstanding share of TSI Common Stock (other than shares, if any, as
to which dissenters' rights, if any, are perfected and shares to be cancelled in
accordance with Section 2.01(b)) shall be converted into the right to receive
0.525 shares (the "Exchange Ratio") of Eclipsys Voting Common Stock. All such
shares of TSI Common Stock, when so converted, shall no longer be outstanding
and shall automatically be cancelled and retired and shall cease to exist, and
each holder of a certificate representing any such shares shall cease to have
any rights with respect thereto, except the right to receive the shares of
Eclipsys Voting Common Stock and any cash in lieu of fractional shares of
Eclipsys Voting Common Stock to be issued or paid in consideration therefor upon
the surrender of such certificate in accordance with Section 2.02, without
interest. Notwithstanding the foregoing, if between the date of this Agreement
and the Effective Time the outstanding shares of Eclipsys Voting Common Stock
shall have been changed into a different number of shares or a different class,
by reason of any stock dividend, subdivision, reclassification,
recapitalization, split, combination or exchange of shares, then the Exchange
Ratio shall be correspondingly adjusted to reflect such stock dividend,
subdivision, reclassification, recapitalization, split, combination or exchange
of shares.

         (d) DISSENTING SHARES. For purposes of this Agreement, "Dissenting
Shares" means shares of TSI Common Stock held as of the Effective Time by a


                                      - 3 -


<PAGE>   12



stockholder of TSI who has not voted such shares in favor of the adoption of
this Agreement and the Merger and with respect to which appraisal shall have
been duly demanded and perfected in accordance with Sections 85 through 98 of
the MBCL and not effectively withdrawn or forfeited prior to the Effective Time.
Dissenting Shares shall not be converted into or represent the right to receive
any shares of Eclipsys Voting Common Stock unless such stockholder's right to
appraisal shall have ceased in accordance with Section 96 of the MBCL. If such
stockholder has so forfeited or withdrawn his right to appraisal of Dissenting
Shares, then (i) as of the occurrence of such event, such holder's Dissenting
Shares shall cease to be Dissenting Shares and shall thereupon be deemed to have
been converted, as of the Effective Time, into and represent shares of Eclipsys
Voting Common Stock, without interest thereon, as provided in Section 2.01(c)
hereof. TSI shall give Eclipsys (x) prompt notice of any written demands for
appraisal of any shares of TSI Common Stock, withdrawals of such demands, and
any other instruments that relate to such demands received by TSI and (y) the
opportunity to direct all negotiations and proceedings with respect to demands
for appraisal under the MBCL. TSI shall not, except with the prior written
consent of Eclipsys, make any payment with respect to any demands for appraisal
of shares of TSI Common Stock or offer to settle or settle any such demands.

         Section 2.02 EXCHANGE OF CERTIFICATES. The procedures for exchanging
outstanding shares of TSI Common Stock for Eclipsys Voting Common Stock pursuant
to the Merger are as follows:

         (a) EXCHANGE AGENT. As of the Effective Time, Eclipsys shall deposit
with a bank or trust company designated by Eclipsys and TSI (the "Exchange
Agent"), for the benefit of the holders of shares of TSI Common Stock, for
exchange in accordance with this Section 2.02, through the Exchange Agent, (i)
certificates representing the shares of Eclipsys Voting Common Stock (such
shares of Eclipsys Voting Common Stock, together with any dividends or
distributions with respect thereto, being hereinafter referred to as the
"Exchange Fund") issuable pursuant to Section 2.01 in exchange for outstanding
shares of TSI Common Stock and (ii) an amount of cash sufficient to fund all
cash payments in lieu of fractional shares to be paid pursuant to subsection (e)
below.

         (b) EXCHANGE PROCEDURES. As soon as reasonably practicable after the
Effective Time, the Exchange Agent shall mail to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of TSI Common Stock (the "Certificates") whose
shares were converted pursuant to Section 2.01 into the right to receive shares
of Eclipsys Voting Common Stock (i) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon delivery of the Certificates to the Exchange Agent and
shall be in such form and have such other provisions as Eclipsys and TSI may
reasonably specify) and (ii) instructions for effecting the surrender of the
Certificates in exchange for certificates representing


                                      - 4 -


<PAGE>   13



shares of Eclipsys Voting Common Stock (plus cash in lieu of fractional shares,
if any, of Eclipsys Voting Common Stock as provided below). Upon surrender of a
Certificate for cancellation to the Exchange Agent or to such other agent or
agents as may be appointed by Eclipsys and TSI, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing that number of whole
shares of Eclipsys Voting Common Stock which such holder has the right to
receive pursuant to the provisions of this Article II, and the Certificate so
surrendered shall immediately be cancelled. In the event of a transfer of
ownership of TSI Common Stock which is not registered in the transfer records of
TSI, a certificate representing the proper number of shares of Eclipsys Voting
Common Stock may be issued to a transferee if the Certificate representing such
TSI 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. Until surrendered as
contemplated by this Section 2.02, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the certificate representing shares of Eclipsys Voting Common Stock
and cash in lieu of any fractional shares of Eclipsys Voting Common Stock as
contemplated by this Section 2.02.

         (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No dividends or
other distributions declared or made after the Effective Time with respect to
Eclipsys Voting Common Stock with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Certificate with respect to the
shares of Eclipsys Voting Common Stock represented thereby and no cash payment
in lieu of fractional shares shall be paid to any such holder pursuant to
subsection (e) below until the holder of record of such Certificate shall
surrender such Certificate. Subject to the effect of applicable laws, following
surrender of any such Certificate, there shall be paid to the record holder of
the certificates representing whole shares of Eclipsys Voting Common Stock
issued in exchange therefor, without interest, (i) at the time of such
surrender, the amount of any cash payable in lieu of a fractional share of
Eclipsys Voting Common Stock to which such holder is entitled pursuant to
subsection (e) below and the amount of dividends or other distributions with a
record date after the Effective Time previously paid with respect to such whole
shares of Eclipsys Voting 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 subsequent to
surrender payable with respect to such whole shares of Eclipsys Voting Common
Stock.

         (d) NO FURTHER OWNERSHIP RIGHTS IN TSI COMMON STOCK. All shares of
Eclipsys Voting Common Stock issued upon the surrender for exchange of
Certificates in accordance with the terms hereof (including any cash paid
pursuant to subsection (c) or (e) of this Section 2.02) shall be deemed to have
been issued in full satisfaction of all rights pertaining to such shares of TSI
Common Stock, subject,


                                      - 5 -


<PAGE>   14



however, to the Surviving Corporation's obligation to pay any dividends or make
any other distributions with a record date prior to the Effective Time which may
have been declared or made by TSI on such shares of TSI Common Stock in
accordance with the terms of this Agreement (to the extent permitted under
Section 5.01) prior to the date hereof and which remain unpaid at the Effective
Time, and from and after the Effective Time there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of TSI Common Stock which 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 cancelled
and exchanged as provided in this Section 2.02.

         (e) NO FRACTIONAL SHARES. No certificate or scrip representing
fractional shares of Eclipsys Voting Common Stock shall be issued upon the
surrender for exchange of Certificates, and such fractional share interests will
not entitle the owner thereof to vote or to any other rights of a stockholder of
Eclipsys. Notwithstanding any other provision of this Agreement, each holder of
shares of TSI Common Stock exchanged pursuant to the Merger who would otherwise
have been entitled to receive a fraction of a share of Eclipsys Voting Common
Stock (after taking into account all Certificates delivered by such holder)
shall receive, in lieu thereof, cash (without interest) in an amount equal to
such fractional part of a share of Eclipsys Voting Common Stock multiplied by
the average of the last reported sales prices of Eclipsys Voting Common Stock,
as reported on the Nasdaq National Market, on each of the ten trading days
immediately preceding the Closing Date.

         (f) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund
which remains undistributed to the stockholders of TSI for 180 days after the
Effective Time shall be delivered to Eclipsys, upon demand, and any stockholders
of TSI who have not previously complied with this Section 2.02 shall thereafter
look only to Eclipsys for payment of their claim for Eclipsys Voting Common
Stock, any cash in lieu of fractional shares of Eclipsys Voting Common Stock and
any dividends or distributions with respect to Eclipsys Voting Common Stock.

         (g) NO LIABILITY. Neither Eclipsys nor TSI shall be liable to any
holder of shares of TSI Common Stock or Eclipsys Voting Common Stock, as the
case may be, for such shares (or dividends or distributions with respect
thereto) delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.

         (h) WITHHOLDING RIGHTS. Each of Eclipsys and the Surviving Corporation
shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of shares of TSI Common Stock
such amounts as it is required to deduct and withhold with respect to the making
of such payment under the Code, or any provision of state, local or foreign tax
law. To the extent that amounts are so withheld by the Surviving Corporation or
Eclipsys, as the case may be, such withheld amounts shall be treated for all
purposes of this

Agreement as having been paid to the holder of the shares of TSI Common Stock in
respect of which such deduction and withholding was made by the Surviving
Corporation or Eclipsys, as the case may be.

         (i) LOST CERTIFICATES. If any Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond in such
reasonable amount as the Surviving Corporation may direct as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the shares of Eclipsys Voting Common Stock and any cash in lieu of
fractional shares, and unpaid dividends and distributions on shares of Eclipsys
Voting Common Stock deliverable in respect thereof pursuant to this Agreement.

         (j) AFFILIATES. Notwithstanding anything herein to the contrary,
Certificates surrendered for exchange by any Affiliate (as defined in Section
6.10) of TSI shall not be exchanged until Eclipsys has received an Affiliate
Agreement (as defined in Section 6.10) from such Affiliate.

                                   ARTICLE III

                      REPRESENTATIONS AND WARRANTIES OF TSI

          TSI represents and warrants to Eclipsys and Sub that the statements
contained in this Article III are true and correct except as set forth in the
disclosure schedule delivered by TSI to Eclipsys on or before the date of this
Agreement (the "TSI Disclosure Schedule"). The TSI Disclosure Schedule shall be
arranged in sections and paragraphs corresponding to the numbered and lettered
sections and paragraphs contained in this Article III and the disclosure in any
section or paragraph shall qualify other sections and paragraphs in this Article
III only to the extent that it is reasonably apparent from a reading of such
disclosure that it also qualifies or applies to such other sections and
paragraphs.

         Section 3.01 ORGANIZATION OF TSI. Each of TSI and its Subsidiaries (as
defined below) is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation, has all
requisite corporate power to own, lease and operate its property and to carry on
its business as now being conducted and as proposed to be conducted, and is duly
qualified to do business and is in good standing as a foreign corporation in
each jurisdiction in which the failure to be so qualified would have a TSI
Material Adverse Effect (as defined below). Except as set forth in the TSI SEC
Reports (as defined in Section 3.04) filed prior to the date hereof, neither TSI
nor any of its Subsidiaries directly or indirectly owns any


                                      - 7 -


<PAGE>   16



equity or similar interest in, or any interest convertible into or exchangeable
or exercisable for, any corporation, partnership, joint venture or other
business association or entity, excluding securities in any publicly traded
company held for investment by TSI and comprising less than five percent (5%) of
the outstanding stock of such company. As used in this Agreement, the word
"Subsidiary" means, with respect to any party, any corporation or other
organization, whether incorporated or unincorporated, of which (i) such party or
any other Subsidiary of such party is a general partner (excluding partnerships,
the general partnership interests of which held by such party or any Subsidiary
of such party do not have a majority of the voting interest in such partnership)
or (ii) at least a majority of the securities or other interests having by their
terms ordinary voting power to elect a majority of the Board of Directors or
others performing similar functions with respect to such corporation or other
organization is directly or indirectly owned or controlled by such party or by
any one or more of its Subsidiaries, or by such party and one or more of its
Subsidiaries. For purposes of this Agreement, the term "TSI Material Adverse
Effect" means any effect that is, or would reasonably be expected to be,
materially adverse to the financial condition, results of operations, cash
flows, business or properties of TSI and its Subsidiaries, taken as a whole.

         Section 3.02 TSI CAPITAL STRUCTURE.

         (a) The authorized capital stock of TSI consists of 30,000,000 shares
of TSI Voting Common Stock, $.01 par value, 1,000,000 shares of TSI Non-Voting
Common Stock, $.01 par value, and 1,000,000 shares of Preferred Stock, $.01 par
value ("TSI Preferred Stock"). As of September 30, 1998, (i) 18,035,983 shares
of TSI Voting Common Stock and 356,262 shares of TSI Non-Voting Common Stock
were issued and outstanding, all of which are validly issued, fully paid and
nonassessable, (ii) 297,928 shares of TSI Non-Voting Common Stock were reserved
for issuance upon the exercise of certain warrants (the "TSI Warrants") having
an exercise price of $.01 per share, and (iii) no shares of TSI Common Stock
were held in the treasury of TSI or by Subsidiaries of TSI. Section 3.02 of the
TSI Disclosure Schedule shows the number of shares of TSI Voting Common Stock
reserved for future issuance pursuant to stock options granted and outstanding
as of September 30, 1998 and the plans under which such options were granted
(collectively, the "TSI Stock Plans"). No material change in such capitalization
has occurred between September 30, 1998 and the date of this Agreement. As of
the date of this Agreement, none of the shares of TSI Preferred Stock is issued
and outstanding. All shares of TSI Common Stock subject to issuance as specified
above are duly authorized and, upon issuance on the terms and conditions
specified in the instruments pursuant to which they are issuable, shall be
validly issued, fully paid and nonassessable. There are no obligations,
contingent or otherwise, of TSI or any of its Subsidiaries to repurchase, redeem
or otherwise acquire any shares of TSI Common Stock or the capital stock of any
Subsidiary or to provide funds to or make any material investment (in the form
of a loan, capital contribution or otherwise) in any such Subsidiary or any
other

                                      - 8 -

entity other than guarantees of bank obligations of Subsidiaries entered into in
the ordinary course of business. All of the outstanding shares of capital stock
of each of TSI's Subsidiaries are duly authorized, validly issued, fully paid
and nonassessable and all such shares (other than directors' qualifying shares
in the case of foreign Subsidiaries) are owned by TSI or another Subsidiary free
and clear of all security interests, liens, claims, pledges, agreements,
limitations in TSI's voting rights, charges or other encumbrances of any nature.

         (b) Except as set forth in this Section 3.02 or as reserved for future
grants of options under the TSI Stock Plans, the TSI Warrants or the Eclipsys
Stock Option Agreement, there are no equity securities of any class of TSI or
any of its Subsidiaries, or any security exchangeable into or exercisable for
such equity securities, issued, reserved for issuance or outstanding. Except as
set forth in the TSI SEC Reports filed prior to the date hereof, in the Eclipsys
Stock Option Agreement or disclosed in Section 3.02 of the TSI Disclosure
Schedule, there are no options, warrants, equity securities, calls, rights,
commitments or agreements of any character to which TSI or any of its
Subsidiaries is a party or by which it is bound obligating TSI or any of its
Subsidiaries to issue, deliver or sell, or cause to be issued, delivered or
sold, additional shares of capital stock of TSI or any of its Subsidiaries or
obligating TSI or any of its Subsidiaries to grant, extend, accelerate the
vesting of or enter into any such option, warrant, equity security, call, right,
commitment or agreement. No consent is required from the holders of TSI Stock
Options (as defined below) in connection with the conversion of the TSI Stock
Options into options to purchase Eclipsys Voting Common Stock as contemplated by
Section 6.12. To the best knowledge of TSI, there are no voting trusts, proxies
or other voting agreements or understandings with respect to the shares of
capital stock of TSI.

         Section 3.03 AUTHORITY; NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

         (a) TSI has all requisite corporate power and authority to enter into
this Agreement and to consummate the transactions contemplated by this
Agreement. The execution and delivery of this Agreement and the consummation of
the transactions contemplated by this Agreement by TSI have been duly authorized
by all necessary corporate action on the part of TSI, subject only to the
approval of the Merger by TSI's stockholders under the MBCL. This Agreement has
been duly executed and delivered by TSI and constitutes the valid and binding
obligation of TSI, enforceable in accordance with its terms, subject to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles (the "Bankruptcy and Equity Exception").

         (b) The execution and delivery of this Agreement by TSI does not, and
the consummation of the transactions contemplated by this Agreement will not,
(i) conflict with, or result in any violation or breach of, any provision of the
Articles

                                      - 9 -


<PAGE>   18



of Organization or Bylaws of TSI, each as amended to date, (ii) result in any
violation or breach of, or constitute (with or without notice or lapse of time,
or both) a default (or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of any material benefit) under, or
require a consent or waiver under, any of the terms, conditions or provisions of
any note, bond, mortgage, indenture, lease, contract or other agreement,
instrument or obligation to which TSI or any of its Subsidiaries is a party or
by which any of them or any of their properties or assets may be bound, or (iii)
conflict with or violate any permit, concession, franchise, license, judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to TSI or
any of its Subsidiaries or any of its or their properties or assets, except in
the case of clauses (ii) and (iii) for any such conflicts, violations, breaches,
defaults, terminations, cancellations, accelerations or losses which are not,
individually or in the aggregate, reasonably likely to have a TSI Material
Adverse Effect.

         (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 ("Governmental Entity") is
required by or with respect to TSI or any of its Subsidiaries in connection with
the execution and delivery of this Agreement or the consummation of the
transactions contemplated hereby, except for (i) the filing of a pre-merger
notification report under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act") and any other documents or information
requested by the United States Department of Justice or the United States
Federal Trade Commission in connection therewith, (ii) the filing of the
Articles of Merger with the Secretary of State of Massachusetts, (iii) the
filing of the Joint Proxy Statement (as defined in Section 3.16 below) with the
Securities and Exchange Commission (the "SEC") in accordance with the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), (iv) such consents,
approvals, orders, authorizations, registrations, declarations and filings as
may be required under applicable state securities laws and the laws of any
foreign country and (v) such other consents, authorizations, filings, approvals
and registrations which, if not obtained or made, would not be reasonably likely
to have a TSI Material Adverse Effect.

         Section 3.04 SEC FILINGS; FINANCIAL STATEMENTS.

         (a) TSI has filed and made available to Eclipsys all forms, reports and
documents required to be filed by TSI with the SEC since April 18, 1996 other
than registration statements on Form S-8 (collectively, the "TSI SEC Reports").
The TSI SEC Reports (i) at the time filed, complied in all material respects
with the applicable requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and the Exchange Act, as the case may be, and (ii) did not at
the time they were filed (or if amended or superseded by a filing prior to the
date of this Agreement, then on the date of such filing) contain any untrue
statement of a material fact or omit to state a material fact required to be
stated in such TSI SEC Reports or necessary in order to

                                     - 10 -


<PAGE>   19



make the statements in such TSI SEC Reports, in the light of the circumstances
under which they were made, not misleading. None of TSI's Subsidiaries is
required to file any forms, reports or other documents with the SEC.

         (b) Each of the consolidated financial statements (including, in each
case, any related notes) contained in the TSI SEC Reports complied as to form in
all material respects with the applicable published rules and regulations of the
SEC with respect thereto, was prepared in accordance with U.S. generally
accepted accounting principles ("GAAP") applied on a consistent basis throughout
the periods involved (except as may be indicated in the notes to such financial
statements or, in the case of unaudited statements, as permitted by Form 10-Q of
the SEC) and fairly presented the consolidated financial position of TSI and its
Subsidiaries as of the dates and the consolidated results of its operations and
cash flows for the periods indicated, except that the unaudited interim
financial statements were or are subject to normal and recurring year-end
adjustments which were not or are not expected to be material in amount. The
unaudited balance sheet of TSI as of June 30, 1998 is referred to herein as the
"TSI Balance Sheet."

         Section 3.05 NO UNDISCLOSED LIABILITIES. Except as disclosed in the TSI
SEC Reports filed prior to the date hereof, and except for normal or recurring
liabilities incurred since June 30, 1998 in the ordinary course of business
consistent with past practices, TSI and its Subsidiaries do not have any
liabilities, either accrued, contingent or otherwise (whether or not required to
be reflected in financial statements in accordance with GAAP), and whether due
or to become due, which individually or in the aggregate are reasonably likely
to have a TSI Material Adverse Effect.

         Section 3.06 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed
in the TSI SEC Reports filed prior to the date hereof, from and after the date
of the TSI Balance Sheet, TSI and its Subsidiaries have conducted their
businesses only in the ordinary course and in a manner consistent with past
practice and, during such period, there has not been (i) any material adverse
change in the financial condition, results of operations, cash flows, business
or properties, subject to the last sentence of this Section 3.06 (a "Material
Adverse Change") of TSI and its Subsidiaries, taken as a whole (other than
changes that are the effect or result of economic factors affecting the economy
as a whole or economic or market factors affecting the healthcare information
systems industry generally) or any development or combination of developments of
which the management of TSI is aware that, individually or in the aggregate, has
had, or is reasonably likely to have, a TSI Material Adverse Effect (other than
economic factors affecting the economy as a whole or economic or market factors
affecting the healthcare information systems industry generally); (ii) any
damage, destruction or loss (whether or not covered by insurance) with respect
to TSI or any of its Subsidiaries having a TSI Material Adverse Effect; (iii)
any material change by TSI in its accounting methods, principles or practices to
which Eclipsys has

                                     - 11 -


<PAGE>   20



not previously consented in writing; (iv) any revaluation by TSI of any of its
assets having a TSI Material Adverse Effect; or (v) any other action or event
that would have required the consent of Eclipsys pursuant to Section 5.01 of
this Agreement had such action or event occurred after the date of this
Agreement and that, in the case of this clause (v), individually or in the
aggregate, has had or is reasonably likely to have a TSI Material Adverse
Effect. Notwithstanding the foregoing, the failure of TSI or Eclipsys to achieve
any level of revenue and earnings at any time shall not of itself constitute a
Material Adverse Change of TSI and its Subsidiaries, taken as a whole, or
Eclipsys and its Subsidiaries, taken as a whole, as the case may be.

         Section 3.07 TAXES.

         (a) For the purposes of this Agreement, a "Tax" or, collectively,
"Taxes" means any and all material federal, state, local and foreign taxes,
assessments and other governmental charges, duties, impositions and liabilities,
including taxes based upon or measured by gross receipts, income, profits,
sales, use and occupation, and value added, ad valorem, transfer, gains,
franchise, withholding, payroll, recapture, employment, excise, unemployment
insurance, social security, business license, occupation, business organization,
stamp, environmental and property taxes, together with all interest, penalties
and additions imposed with respect to such amounts. "Tax Returns" means all
reports, returns, declarations, statements or other information required to be
supplied to a taxing authority in connection with Taxes.

         (b) Each of TSI and its Subsidiaries has filed all Tax Returns that it
was required to file, and all such Tax Returns were correct and complete. Each
group of corporations with which TSI or any of its Subsidiaries has filed (or
was required to file) consolidated, combined, unitary or similar Tax Returns (a
"TSI Affiliated Group") has filed all such Tax Returns that it was required to
file with respect to any period in which TSI or one of its Subsidiaries was a
member of such TSI Affiliated Group (a "TSI Affiliated Period"), and all such
Tax Returns were correct and complete. Each of TSI and its Subsidiaries has paid
all Taxes (whether or not shown on such Tax Returns) that were due and payable,
and each TSI Affiliated Group has paid all Taxes (whether or not shown on such
Tax Returns) that were due and payable with respect to all TSI Affiliated
Periods and with respect to which TSI or any of its Subsidiaries may be liable
by operation of law or otherwise. The unpaid Taxes of TSI and its Subsidiaries
for tax periods through the date of the TSI Balance Sheet do not exceed the
accruals and reserves for Taxes set forth on the TSI Balance Sheet (exclusive of
any accruals for "deferred taxes" or similar items that reflect timing
differences between Tax and financial accounting principles). The unpaid Taxes
of TSI and its Subsidiaries for tax periods from the date of the TSI Balance
Sheet through the Closing Date are attributable solely to the conduct of their
businesses in the ordinary course and in a manner consistent with past
practices. All Taxes that TSI or any of its Subsidiaries is or was required by
law to withhold or collect have been duly withheld or collected and, to the
extent required, have been paid to the proper

                                     - 12 -


<PAGE>   21



Governmental Entity. Each of the representations contained in this Section
3.07(b) shall be limited in its application to items which are reasonably
likely, individually or in the aggregate, to have a TSI Material Adverse Effect.

         (c) No examination or audit by any Governmental Entity of any Tax
Return of TSI, any of its Subsidiaries or any TSI Affiliated Group with respect
to a TSI Affiliated Period is currently in progress or, to the knowledge of TSI
and its Subsidiaries, threatened or contemplated, in each case, which involve
claims that individually or in the aggregate are reasonably likely to have a TSI
Material Adverse Effect. Neither TSI nor any of its Subsidiaries has been
informed by any jurisdiction that the jurisdiction believes that TSI or any of
its Subsidiaries was required to file any Tax Return that was not filed which
failure or failures individually, or in the aggregate, are reasonably likely to
have a TSI Material Adverse Effect.

         (d) Neither TSI nor any of its Subsidiaries is a "consenting
corporation" within the meaning of Section 341(f) of the Code, and none of the
assets of TSI and its Subsidiaries is subject to an election under Section
341(f) of the Code.

         (e) Neither TSI nor any of its Subsidiaries has been a United States
real property holding corporation within the meaning of Section 897(c)(2) of the
Code during the applicable period specified in Section 897(c)(l)(A)(ii) of the
Code.

         (f) None of TSI or any of its Subsidiaries is a party to any Tax
allocation or sharing agreement.

         (g) None of TSI or any of its Subsidiaries has any material liability
for Taxes of any person (other than TSI or any of its Subsidiaries (under
Treasury Regulation Section 1.1502-6 or any similar provision of state, local or
foreign law)), as a transferee or successor, by contract, or otherwise.

         Section 3.08 PROPERTIES.

         (a) TSI does not own of record any real property.

         (b) All material real property leases of TSI and its Subsidiaries are
in good standing, valid and effective in accordance with their respective terms,
and neither TSI nor any of its Subsidiaries is in default under any of such
leases, except where the lack of such good standing, validity or effectiveness
or the existence of such default would not be reasonably likely to have a TSI
Material Adverse Effect.

         Section 3.09 INTELLECTUAL PROPERTY.

         (a) TSI and its Subsidiaries own, or are licensed or otherwise possess
legally enforceable rights to use, all patents, trademarks, trade names, service
marks,

                                     - 13 -


<PAGE>   22



copyrights and mask works, any applications for and registrations of such
patents, trademarks, trade names, service marks, copyrights and mask works, and
all processes, formulae, methods, schematics, technology, know-how, computer
software programs or applications and tangible or intangible proprietary
information or material that are necessary to conduct the business of TSI and
its Subsidiaries as currently conducted, or planned to be conducted, the absence
of which would be reasonably likely to have a TSI Material Adverse Effect (the
"TSI Intellectual Property Rights"). Section 3.09 of the TSI Disclosure Schedule
sets forth a complete and accurate list of (i) all patents, registered
copyrights, registered trademarks, registered service marks and all software
programs, other than commercial, off-the-shelf software, subject to a perpetual
license, in connection with which no future license fees or royalties are due
("Off-the-Shelf Software"), owned, used or licensed by or to TSI or any of its
Subsidiaries and (ii) all other intellectual property that is licensed by or to
TSI or any of its Subsidiaries that is used in or is necessary for the conduct
of TSI's business. TSI has promulgated and used commercially reasonable efforts
to enforce the trade secret protection program described in Section 3.09 of the
TSI Disclosure Schedule.

         (b) Neither TSI nor any of its Subsidiaries is, or will as a result of
the execution and delivery of this Agreement or the performance of TSI's
obligations under this Agreement or otherwise be, in breach of any license,
sublicense or other agreement relating to the TSI Intellectual Property Rights,
or any material licenses, sublicenses and other agreements as to which TSI or
any of its Subsidiaries is a party and pursuant to which TSI or any of its
Subsidiaries is authorized to use any third party patents, trademarks or
copyrights ("TSI Third Party Intellectual Property Rights"), including software
which is used in the manufacture of, incorporated in, or forms a part of any
product sold by or expected to be sold by TSI or any of its Subsidiaries, the
breach of which would be reasonably likely to have a TSI Material Adverse
Effect.

         (c) All patents, registered trademarks, registered service marks and
registered copyrights which are held by TSI or any of its Subsidiaries and which
are material to the business of TSI and its Subsidiaries, taken as a whole, are
valid and subsisting. TSI (i) has not been sued in any suit, action or
proceeding, or received in writing any claim or notice, which involves a claim
of infringement of any patents, trademarks, service marks, copyrights or
violation of any trade secret or other proprietary right of any third party; and
(ii) has no knowledge that the manufacturing, marketing, licensing or sale of
its products infringes any patent, trademark, service mark, copyright, trade
secret or other proprietary right of any third party, which infringement would
reasonably be expected to have a TSI Material Adverse Effect.

         (d) Section 3.09 of the TSI Disclosure Schedule identifies each "year
2000" audit, report or investigation that has been performed by or on behalf of
TSI with

                                     - 14 -


<PAGE>   23



respect to its business and operations, and TSI has provided to Eclipsys true
and correct copies of all such audits, reports or investigations. Except as set
forth in such audits, reports and investigations, TSI is not aware of any
failure to be Year 2000 Compliant of (i) any software products sold or licensed
by TSI or any of its Subsidiaries to third parties or (ii) any computer software
products used by or licensed to TSI or its Subsidiaries from third parties for
internal use by TSI or its Subsidiaries. For purposes of this Agreement, "Year
2000 Compliant" means, with respect to each software product referred to in the
prior sentence, that such system (i) will accurately receive, record, store,
provide, recognize and process all date and time data from, during, into and
between the twentieth and twenty-first centuries; (ii) will accurately perform
all date-dependent calculations and operations (including, without limitation,
mathematical operations, sorting, comparing and reporting) from, during, into
and between the twentieth and twenty-first centuries; and (iii) will not
malfunction, cease to function or provide invalid or incorrect results as a
result of (x) the change of century, (y) date data, including date data which
represents or references different centuries or more than one century or (z) the
occurrence of any particular date; in each case without human intervention,
other than original data entry; provided, in each case, that all applications,
hardware and other systems used in conjunction with such system which are not
owned or licensed by TSI correctly exchange date data with or provide data to
such system. Except as set forth in Section 3.09(d) of the TSI Disclosure
Statement, TSI has not provided any guarantee or warranty for any product sold
or licensed, or services provided, by TSI to the effect that such product or
service (i) complies with or accounts for the fact of the arrival of the year
2000 or (ii) will not be adversely affected with respect to functionally
interoperability, performance or volume capacity (including without limitation
the processing and reporting of data) by virtue of the arrival of the year 2000.

         Section 3.10 AGREEMENTS, CONTRACTS AND COMMITMENTS. Except as set forth
on Section 3.10 of the TSI Disclosure Schedule, neither TSI nor any of its
Subsidiaries, nor any of their respective assets, businesses, or operations, is
a party to, or is bound or affected by, or receives benefits under (i) any
severance, termination or retirement agreement or any employment or consulting
agreement providing for aggregate payments to any person in any calendar year in
excess of $100,000 or continuing for more than one year, (ii) any agreement
relating to the borrowing of money by TSI or any of its Subsidiaries or the
guarantee by any TSI or any of its Subsidiaries of any such obligation (other
than agreements evidencing trade payables or relating to borrowings or
guarantees made in the ordinary course of business), (iii) any agreement which
prohibits or restricts TSI or any of its Subsidiaries from engaging in any
business activities in any geographic area, line of business or otherwise in
competition with any other person, (iv) any agreement involving TSI Intellectual
Property Rights or TSI Third Party Intellectual Property Rights (other than
Off-the-Shelf Software licenses) which provide for annual payments of $100,000
or more, (v) any agreement relating to the provision of computer software,
computer

                                     - 15 -


<PAGE>   24



hardware, data processing systems or equipment, network communication,
transactional billing, management information or other technical systems or
services, including maintenance with respect to the foregoing matters, to or by
TSI or any of its Subsidiaries which provides for annual payments of $100,000 or
more, (vi) any agreement relating to the purchase or lease of real property, and
(vii) any other agreement or amendment thereto that would be required to be
filed as an exhibit to a Form 10-K filed by TSI with the SEC as of the date of
this Agreement (collectively, the "TSI Material Contracts"). With respect to
each TSI Material Contract and except as disclosed in Section 3.10 of the TSI
Disclosure Schedule: (i) the TSI Material Contract is in full force and effect;
(ii) neither TSI nor any of its Subsidiaries is in default or breach thereunder
in any material respect; (iii) neither TSI nor any of its Subsidiaries has
repudiated or waived any material provision of any such TSI Material Contract;
(iv) no other party to any such TSI Material Contract is, to the knowledge of
TSI, in default or breach in any material respect or has repudiated or waived
any material provision thereunder; (v) there exists no actual, or, to the
knowledge of TSI, threatened, cancellation, termination, or limitation of, or
any amendment, modification, or change to, any TSI Material Contract; (vi)
neither TSI nor any of its Subsidiaries has received formal notice that any
party to a TSI Material Contract will not renew such contract at the end of its
existing term; and (vii) no TSI Material Contract requires consent or notice in
connection with the transactions contemplated by this Agreement. All of the
indebtedness of TSI or any of its Subsidiaries for money borrowed is prepayable
at any time without penalty or premium.

         Section 3.11 LITIGATION. Except as described in the TSI SEC Reports
filed prior to the date hereof, there is no action, suit or proceeding, claim,
arbitration or investigation against TSI or any of its Subsidiaries pending or
as to which TSI or any such Subsidiary has received any written notice of
assertion, which, individually or in the aggregate, is reasonably likely to have

         (a) TSI has listed in Section 3.13 of the TSI Disclosure Schedule all

         Section 3.15 ACCOUNTING AND TAX MATTERS. To its knowledge, after

reputable insurance carriers, provide full and adequate coverage for all normal
risks incident to the business of TSI and its Subsidiaries and their respective
properties and assets, and are in character and amount at least equivalent to
that carried by persons engaged in similar businesses and subject to the same or
similar perils or hazards, except for any such failures to maintain insurance

risks incident to the business and operations of TSI and its Subsidiaries and
their respective properties and assets are at least equivalent to those taken by
persons engaged in similar businesses, except for any failures to take such
steps that, individually or in the aggregate, are not reasonably likely to have

          Eclipsys and Sub represent and warrant to TSI that the statements
contained in this Article IV are true and correct except as set forth in the
disclosure schedule

                                     - 20 -

delivered by Eclipsys to TSI on or before the date of this Agreement (the
"Eclipsys Disclosure Schedule"). The Eclipsys Disclosure Schedule shall be
arranged in paragraphs and sections corresponding to the numbered and lettered
paragraphs and sections contained in this Article IV and the disclosure in any
paragraph or section shall qualify other paragraphs and sections in this Article
IV only to the extent that it is reasonably apparent from a reading of such
document that it also qualifies or applies to such other paragraphs and
sections.

         Section 4.01 ORGANIZATION OF ECLIPSYS AND SUB. Each of Eclipsys and Sub
and Eclipsys' other Subsidiaries is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation, has all requisite corporate power to own, lease and operate its
property and to carry on its business as now being conducted and as proposed to
be conducted, and is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction in which the failure to be so qualified
would have an Eclipsys Material Adverse Effect (as defined below). Except as set
forth in the Eclipsys SEC Reports (as defined in Section 4.04) filed prior to
the date hereof, neither Eclipsys nor any of its Subsidiaries directly or
indirectly owns any equity or similar interest in, or any interest convertible
into or exchangeable or exercisable for, any corporation, partnership, joint
venture or other business association or entity, excluding securities in any
publicly traded company held for investment by Eclipsys and comprising less than
five percent (5%) of the outstanding stock of such company. For purposes of this
Agreement, the term "Eclipsys Material Adverse Effect" means any effect that is,
or would reasonably be expected to be, materially adverse to the financial
condition, results of operations, cash flows, business or properties of Eclipsys
and its Subsidiaries, taken as a whole.

         Section 4.02 ECLIPSYS CAPITAL STRUCTURE.

         (a) The authorized capital stock of Eclipsys consists of 200,000,000
shares of Eclipsys Voting Common Stock, $.01 par value, 5,000,000 shares of
Non-Voting Common Stock, $.01 par value ("Eclipsys Non-Voting Common Stock" and,
together with the Eclipsys Voting Common Stock, "Eclipsys Common Stock"), and
5,000,000 shares of Preferred Stock, $.01 par value ("Eclipsys Preferred
Stock"). As of September 30, 1998, (i) 19,393,241 shares of Eclipsys Voting
Common Stock and 896,431 shares of Eclipsys Non-Voting Common Stock were issued
and outstanding, all of which are validly issued, fully paid and nonassessable,
(ii) 962,833 shares of Eclipsys Non-Voting Common Stock were reserved for
issuance upon the exercise of certain warrants (the "Eclipsys Warrants") having
an exercise price of $.01 per share, and (iii) no shares of Eclipsys Common
Stock were held in the treasury of Eclipsys or by Subsidiaries of Eclipsys.
Section 4.02 of the Eclipsys Disclosure Schedule shows the number of shares of
Eclipsys Voting Common Stock reserved for future issuance pursuant to stock
options granted and outstanding as of September 30, 1998 and the plans under
which such options were granted (collectively, the "Eclipsys Stock

                                     - 21 -

Plans"). No material change in such capitalization has occurred between
September 30, 1998 and the date of this Agreement. As of the date of this
Agreement, none of the shares of Eclipsys Preferred Stock is issued and
outstanding. All shares of Eclipsys Common Stock subject to issuance as
specified above are duly authorized and, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are issuable,
shall be validly issued, fully paid and nonassessable. There are no obligations,
contingent or otherwise, of Eclipsys or any of its Subsidiaries to repurchase,
redeem or otherwise acquire any shares of Eclipsys Common Stock or the capital
stock of any Subsidiary or to provide funds to or make any material investment
(in the form of a loan, capital contribution or otherwise) in any such
Subsidiary or any other entity other than guarantees of bank obligations of
Subsidiaries entered into in the ordinary course of business. All of the
outstanding shares of capital stock of each of Eclipsys' Subsidiaries are duly
authorized, validly issued, fully paid and nonassessable and all such shares
(other than directors' qualifying shares in the case of foreign Subsidiaries)
are owned by Eclipsys or another Subsidiary free and clear of all security
interests, liens, claims, pledges, agreements, limitations in Eclipsys' voting
rights, charges or other encumbrances of any nature.

         (b) Except as set forth in this Section 4.02 or as reserved for future
grants of options under the Eclipsys Stock Plans or the Eclipsys Warrant, there
are no equity securities of any class of Eclipsys or any of its Subsidiaries, or
any security exchangeable into or exercisable for such equity securities,
issued, reserved for issuance or outstanding. Except as set forth in the
Eclipsys SEC Reports (as defined in Section 4.04 below) filed prior to the date
hereof or disclosed in Section 4.02 of the Eclipsys Disclosure Schedule, there
are no options, warrants, equity securities, calls, rights, commitments or
agreements of any character to which Eclipsys or any of its Subsidiaries is a
party or by which it is bound obligating Eclipsys or any of its Subsidiaries to
issue, deliver or sell, or cause to be issued, delivered or sold, additional
shares of capital stock of Eclipsys or any of its Subsidiaries or obligating
Eclipsys or any of its Subsidiaries to grant, extend, accelerate the vesting of
or enter into any such option, warrant, equity security, call, right, commitment
or agreement. To the best knowledge of Eclipsys, there are no voting trusts,
proxies or other voting agreements or understandings with respect to the shares
of capital stock of Eclipsys.

         Section 4.03 AUTHORITY; NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

         (a) Each of Eclipsys and the Sub has all requisite corporate power and
authority to enter into this Agreement and to consummate the transactions
contemplated by this Agreement. The execution and delivery of this Agreement and
the consummation of the transactions contemplated by this Agreement by Eclipsys
have been duly authorized by all necessary corporate action on the part of each
of Eclipsys and Sub (including the approval of the Merger by Eclipsys as the
sole stockholder of Sub), subject only to the approval of the Eclipsys Voting
Proposals (as

                                     - 22 -

defined in Section 6.05) by Eclipsys' stockholders. This Agreement has been duly
executed and delivered by Eclipsys and the Sub and constitutes the valid and
binding obligation of Eclipsys and the Sub, enforceable in accordance with its
terms, subject to the Bankruptcy and Equity Exception.

         (b) The execution and delivery of this Agreement by Eclipsys and the
Sub does not, and the consummation of the transactions contemplated by this
Agreement will not, (i) conflict with, or result in any violation or breach of,
any provision of the Certificate of Incorporation or Bylaws of Eclipsys or Sub,
each as amended to date, (ii) result in any violation or breach of, or
constitute (with or without notice or lapse of time, or both) a default (or give
rise to a right of termination, cancellation or acceleration of any obligation
or loss of any material benefit) under, or require a consent or waiver under,
any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, lease, contract or other agreement, instrument or obligation to which
Eclipsys or any of its Subsidiaries is a party or by which any of them or any of
their properties or assets may be bound, or (iii) conflict with or violate any
permit, concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to Eclipsys or any of its Subsidiaries
or any of its or their properties or assets, except in the case of clauses (ii)
and (iii) for any such conflicts, violations, breaches, defaults, terminations,
cancellations, accelerations or losses which are not, individually or in the
aggregate, reasonably likely to have an Eclipsys Material Adverse Effect.

         (c) No consent, approval, order or authorization of, or registration,
declaration or filing with, any Governmental Entity is required by or with
respect to Eclipsys or any of its Subsidiaries in connection with the execution
and delivery of this Agreement or the consummation of the transactions
contemplated hereby, except for (i) the filing of a pre-merger notification
report under the HSR Act and any other documents or information requested by the
United States Department of Justice or the United States Federal Trade
Commission in connection herewith, (ii) the filing of the Registration Statement
with the SEC in accordance with the Securities Act, (iii) the filing of the
Articles of Merger with the Secretary of State of Massachusetts, (iv) the filing
of the Joint Proxy Statement with the SEC in accordance with the Exchange Act,

declarations and filings as may be required under applicable state securities
laws and the laws of any foreign country and (vi) such other consents,
authorizations, filings, approvals and registrations which, if not obtained or
made, would not be reasonably likely to have an Eclipsys Material Adverse
Effect.

         Section 4.04 SEC FILINGS; FINANCIAL STATEMENTS.

         (a) Eclipsys has filed and made available to TSI all forms, reports and
documents required to be filed by Eclipsys with the SEC since July 29, 1998
other than registration statements on Form S-8 (collectively, the "Eclipsys SEC
Reports").

                                     - 23 -


<PAGE>   32



The Eclipsys SEC Reports (i) at the time filed, complied in all material
respects with the applicable requirements of the Securities Act and the Exchange
Act, as the case may be, and (ii) did not at the time they were filed (or if
amended or superseded by a filing prior to the date of this Agreement, then on
the date of such filing) contain any untrue statement of a material fact or omit
to state a material fact required to be stated in such Eclipsys SEC Reports or
necessary in order to make the statements in such Eclipsys SEC Reports, in the
light of the circumstances under which they were made, not misleading. None of
Eclipsys' Subsidiaries is required to file any forms, reports or other documents
with the SEC.

         (b) Each of the consolidated financial statements (including, in each
case, any related notes) contained in the Eclipsys SEC Reports complied as to
form in all material respects with the applicable published rules and
regulations of the SEC with respect thereto, was prepared in accordance with
GAAP applied on a consistent basis throughout the periods involved (except as
may be indicated in the notes to such financial statements or, in the case of
unaudited statements, as permitted by Form 10-Q of the SEC) and fairly presented
the consolidated financial position of Eclipsys and its Subsidiaries as of the
dates and the consolidated results of its operations and cash flows for the
periods indicated, except that the unaudited interim financial statements were
or are subject to normal and recurring year-end adjustments which were not or
are not expected to be material in amount. The unaudited balance sheet of
Eclipsys as of June 30, 1998 is referred to herein as the "Eclipsys Balance
Sheet."

         Section 4.05 NO UNDISCLOSED LIABILITIES. Except as disclosed in the
Eclipsys SEC Reports filed prior to the date hereof, and except for normal or
recurring liabilities incurred since June 30, 1998 in the ordinary course of
business consistent with past practices, Eclipsys and its Subsidiaries do not
have any liabilities, either accrued, contingent or otherwise (whether or not
required to be reflected in financial statements in accordance with GAAP), and
whether due or to become due, which individually or in the aggregate, are
reasonably likely to have an Eclipsys Material Adverse Effect.

         Section 4.06 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed
in the Eclipsys SEC Reports filed prior to the date hereof, from and after the
date of the Eclipsys Balance Sheet, Eclipsys and its Subsidiaries have conducted
their businesses only in the ordinary course and in a manner consistent with
past practice and, during such period, there has not been (i) any Material
Adverse Change in Eclipsys and its Subsidiaries, taken as a whole (other than
changes that are the effect or result of economic factors affecting the economy
as a whole or economic or market factors affecting the healthcare information
systems industry generally) or any development or combination of developments of
which the management of Eclipsys is aware that, individually or in the
aggregate, has had, or is reasonably likely to have, an Eclipsys Material
Adverse Effect (other than economic factors affecting the economy as a

                                     - 24 -


<PAGE>   33



whole or economic or market factors affecting the healthcare information systems
industry generally); (ii) any damage, destruction or loss (whether or not
covered by insurance) with respect to Eclipsys or any of its Subsidiaries having
an Eclipsys Material Adverse Effect; (iii) any material change by Eclipsys in
its accounting methods, principles or practices to which TSI has not previously
consented in writing; (iv) any revaluation by Eclipsys of any of its assets
having an Eclipsys Material Adverse Effect; or (v) any other action or event
that would have required the consent of TSI pursuant to Section 5.01 of this
Agreement had such action or event occurred after the date of this Agreement and
that, in the case of this clause (v), individually or in the aggregate, has had
or is reasonably likely to have an Eclipsys Material Adverse Effect.

         Section 4.07 TAXES.

         (a) Each of Eclipsys and its Subsidiaries has filed all Tax Returns
that it was required to file, and all such Tax Returns were correct and
complete. Each group of corporations with which Eclipsys or any of its
Subsidiaries has filed (or was required to file) consolidated, combined, unitary
or similar Tax Returns (an "Eclipsys Affiliated Group") has filed all such Tax
Returns that it was required to file with respect to any period in which
Eclipsys or one of its Subsidiaries was a member of such Eclipsys Affiliated
Group (an "Eclipsys Affiliated Period"), and all such Tax Returns were correct
and complete. Each of Eclipsys and its Subsidiaries has paid all Taxes (whether
or not shown on such Tax Returns) that were due and payable, and each Eclipsys
Affiliated Group has paid all Taxes (whether or not shown on such Tax Returns)
that were due and payable with respect to all Eclipsys Affiliated Periods and
with respect to which Eclipsys or any of its Subsidiaries may be liable by
operation of law or otherwise. The unpaid Taxes of Eclipsys and its Subsidiaries
for tax periods through the date of the Eclipsys Balance Sheet do not exceed the
accruals and reserves for Taxes set forth on the Eclipsys Balance Sheet
(exclusive of any accruals for "deferred taxes" or similar items that reflect
timing differences between Tax and financial accounting principles). The unpaid
Taxes of Eclipsys and its Subsidiaries for tax periods from the date of the
Eclipsys Balance Sheet through the Closing Date are attributable solely to the
conduct of their businesses in the ordinary course and in a manner consistent
with past practices. All Taxes that Eclipsys or any of its Subsidiaries is or
was required by law to withhold or collect have been duly withheld or collected
and, to the extent required, have been paid to the proper Governmental Entity.
Each of the representations contained in this Section 4.07(a) shall be limited
in its application to items which are reasonably likely, individually or in the
aggregate, to have an Eclipsys Material Adverse Effect.

         (b) No examination or audit by any Governmental Entity of any Tax
Return of Eclipsys, any of its Subsidiaries or any Eclipsys Affiliated Group
with respect to an Eclipsys Affiliated Period is currently in progress or, to
the knowledge of Eclipsys and its Subsidiaries, threatened or contemplated, in
each case, which involve claims

                                     - 25 -

that individually or in the aggregate are reasonably likely to have an Eclipsys
Material Adverse Effect. Neither Eclipsys nor any of its Subsidiaries has been
informed by any jurisdiction that the jurisdiction believes that Eclipsys or any
of its Subsidiaries was required to file any Tax Return that was not filed which
failure or failures individually, or in the aggregate, are reasonably likely to
have an Eclipsys Material Adverse Effect.

         (c) Neither Eclipsys nor any of its Subsidiaries is a "consenting
corporation" within the meaning of Section 341(f) of the Code, and none of the
assets of Eclipsys and its Subsidiaries is subject to an election under Section
341(f) of the Code.

         (d) Neither Eclipsys nor any of its Subsidiaries has been a United
States real property holding corporation within the meaning of Section 897(c)(2)
of the Code during the applicable period specified in Section 897(c)(l)(A)(ii)
of the Code.

         (e) None of Eclipsys or any of its Subsidiaries is a party to any Tax
allocation or sharing agreement.

         (a) TSI and Eclipsys each shall not, directly or indirectly, through
any officer, director, employee, financial advisor, representative or agent of

of shares of capital stock (including without limitation by way of a tender
offer) or similar transaction involving such party or any of its Subsidiaries,
other than the transactions contemplated by this Agreement and other than, in
the case of Eclipsys, transactions constituting Eclipsys Permitted Acquisitions
(any of the foregoing inquiries or proposals being referred to in this Agreement
as an "Acquisition Proposal"), (ii) engage in negotiations or discussions
concerning, or provide any non-public information to any person or entity
relating to, any Acquisition Proposal, or (iii) agree to or recommend any
Acquisition Proposal; provided, however, that nothing contained in this

Directors, from (A) furnishing non-public information to, or entering into
discussions or negotiations with, any person or entity in connection with an
unsolicited bona fide written Acquisition Proposal by such person or entity or
recommending an unsolicited bona fide written Acquisition Proposal by such
person or entity or recommending an unsolicited bona fide written Acquisition
Proposal to the stockholders of such party, if and only to the extent that (1)
the Board of Directors of such party believes in good faith (after consultation
with its financial advisor) that such Acquisition Proposal is reasonably capable
of being completed on the terms proposed and, after taking into account, among
other relevant factors, the strategic benefits anticipated to be derived from
the Merger and the long-term prospects of TSI and Eclipsys as a combined
company, would, if consummated, result in a transaction more favorable to the
stockholders of such party than the transactions contemplated by this Agreement
(any such more favorable Acquisition Proposal being referred to in this
Agreement as a "Superior Proposal") and the Board of Directors of such party

                                     - 36 -


<PAGE>   45



determines in good faith after consultation with outside legal counsel that such
action is necessary for such Board of Directors to comply with its fiduciary
duties to stockholders under applicable law and (2) prior to furnishing such
non-public information to, or entering into discussions or negotiations with,

laws and the rules and regulations thereunder.

Subsidiaries, to cooperate and to use their respective best efforts to obtain
any government clearances or approvals required for the Closing under the HSR
Act, the Sherman Act, as amended, the Clayton Act, as amended, the Federal Trade

Agreement under any Antitrust Law. The parties hereto will consult and cooperate
with one another, and consider in good faith the views of one another, in

the event of a challenge to the transactions contemplated by this Agreement
pursuant to the HSR Act, TSI and Eclipsys shall use their best efforts to defeat
such challenge, including by institution and defense of litigation, or to settle
such challenge on terms that permit the consummation of the Merger; provided,

Material Adverse Effect. Without limiting the foregoing, in the event that

respond fully to such Second Request within 20 days after its receipt and shall
promptly make any further filings or information submissions and make any
employee available for interview or testimony pursuant to the foregoing (both

In case at any time after the Effective Time any further action is necessary or
desirable to carry out the purposes of this Agreement or to vest the Surviving
Corporation with full title to all properties, assets, rights, approvals,
immunities and franchises of either of the Constituent Corporations, the proper
officers and directors of each party to this Agreement shall take all such
necessary or desirable action.

         (c) Each of TSI and Eclipsys shall give (and shall cause their
respective Subsidiaries to give) any notices to third parties, and use, and

action, that is reasonably likely to jeopardize the treatment of the Merger as a
pooling of interests for accounting purposes.

         Section 6.10 AFFILIATE AGREEMENTS. Upon the execution of this
Agreement, Eclipsys and TSI will provide each other with a list of those persons
who are, in Eclipsys' or TSI's respective reasonable judgment, "affiliates" of

the Securities Act

                                     - 40 -


<PAGE>   49



("Rule 145") (each such person who is an "affiliate" of Eclipsys or TSI within
the meaning of Rule 145 is referred to as an "Affiliate"). Eclipsys and TSI
shall provide each other with such information and documents as TSI or Eclipsys
shall reasonably request for purposes of reviewing such list and shall notify
the other party in writing regarding any change in the identity of its
Affiliates prior to the Closing Date. TSI and Eclipsys shall each use its best
efforts to deliver or cause to be delivered to each other by November 20, 1998
(and in any case prior to the Effective Time) from each of its Affiliates, an
executed Affiliate Agreement, in form attached hereto as EXHIBIT B-1, in the
case of Affiliates of TSI, and in the form attached hereto as EXHIBIT B-2, in
the case of Affiliates of Eclipsys (each, an "Affiliate Agreement"). Eclipsys
shall be entitled to place appropriate legends on the certificates evidencing
any Eclipsys Voting Common Stock to be received by such Affiliates of TSI
pursuant to the terms of this Agreement, and to issue appropriate stop transfer
instructions to the transfer agent for the Eclipsys Voting Common Stock,
consistent with the terms of the Affiliate Agreements (provided that such
legends or stop transfer instructions shall be removed, two years after the
Effective Date, upon the request of any stockholder that is not then an
Affiliate of Eclipsys).

         Section 6.11 NASDAQ QUOTATION. Eclipsys shall use its best efforts to
cause the shares of Eclipsys Voting Common Stock to be issued in the Merger to
be approved for quotation on the Nasdaq National Market, subject to official
notice of issuance, prior to the Closing Date.

         Section 6.12 STOCK PLANS AND WARRANTS.

         (a) At the Effective Time, each outstanding option to purchase shares
of TSI Voting Common Stock (a "TSI Stock Option") under the TSI Stock Plans,
whether vested or unvested, shall be deemed to constitute an option to acquire,
but otherwise on the same terms and conditions as were applicable under such TSI
Stock Option, the same number of shares of Eclipsys Voting Common Stock as the
holder of such TSI Stock Option would have been entitled to receive pursuant to
the Merger had such holder exercised such option in full immediately prior to
the Effective Time (rounded downward to the nearest whole number), at a price
per share (rounded upward to the nearest whole cent) equal to (y) the aggregate
exercise price for the shares of TSI Voting Common Stock purchasable pursuant to
such TSI Stock Option immediately prior to the Effective Time divided by (z) the
number of full shares of Eclipsys Voting Common Stock deemed purchasable
pursuant to such TSI Voting Stock Option in accordance with the foregoing. The
adjustment pursuant to this Section 6.12(a) is intended to comply with Section
424(a) of the Code with respect to any options which are incentive stock options
and shall be construed consistent with Section 424(a) of the Code.

         (b) At the Effective Time, each outstanding TSI Warrant shall be deemed
to constitute a warrant to acquire, on the same terms and conditions as were
applicable

                                     - 41 -


<PAGE>   50



under such TSI Warrant, the number of shares of Eclipsys Voting Common Stock at
the price per share as shall be determined under the existing terms of the
respective TSI Warrant.

         (c) As soon as practicable after the Effective Time, Eclipsys shall
deliver to the participants in the TSI Stock Plans appropriate notice setting
forth such participants' rights pursuant thereto and the grants pursuant to the
TSI Stock Plans shall continue in effect on the same terms and conditions
(subject to the adjustments required by this Section 6.12 after giving effect to
the Merger).

         (d) Eclipsys shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Eclipsys Voting Common Stock for
delivery under the TSI Stock Plans assumed in accordance with this Section 6.12
and the TSI Warrants. As soon as practicable after the Effective Time, Eclipsys
shall file a registration statement on Form S-8 (or any successor or other
appropriate forms), or another appropriate form with respect to the shares of
Eclipsys Voting Common Stock subject to such options, and shall use its best
efforts to maintain the effectiveness of such registration statement or
registration statements (and maintain the current status of the prospectus or
prospectuses contained therein) for so long as such options remain outstanding.

         (e) The Board of Directors of TSI shall, prior to or as of the
Effective Time, take any necessary actions, pursuant to and in accordance with
the terms of the TSI Stock Plans and the instruments evidencing the TSI Stock
Options, to provide for the conversion of the TSI Stock Options into options to
acquire Eclipsys Voting Common Stock in accordance with this Section 6.12.

         (f) TSI shall terminate its Employee Stock Purchase Plan (the "Stock
Purchase Plan") as of or prior to the Effective Time; provided, however, that,
in accordance with Section 17 of the Stock Purchase Plan, said termination shall
not affect the rights of participants in the Stock Purchase Plan to purchase
shares pursuant to the current offering under the Stock Purchase Plan which
commenced on October 1, 1998 and which terminates on March 31, 1999. Eclipsys
and TSI acknowledge and agree that, assuming that the Effective Time of the
Merger occurs prior to April 1, 1999, participants in the current offering under
the Stock Purchase Plan shall have the right to purchase a number of shares of
Eclipsys Voting Common Stock determined by applying the Exchange Ratio to the
number of shares of TSI Voting Common Stock that such participants would have
been entitled to purchase had the Merger not been completed at such time and
that such purchase shall occur at an exercise price equal to 85% of the lower of
(x) the market value (determined in accordance with the Stock Purchase Plan) of
TSI Common Stock as of October 1, 1998 or (y) the product of (I) the Exchange
Ratio and (II) the market value (determined in accordance with the Stock
Purchase Plan) of Eclipsys Voting Common Stock as of

                                     - 42 -

March 31, 1999, all subject to and in accordance with the terms of the Stock
Purchase Plan.

         Section 6.13 BROKERS OR FINDERS. Each of Eclipsys and TSI represents,
as to itself, its Subsidiaries and its Affiliates, that no agent, broker,
investment banker, financial advisor or other firm or person is or will be
entitled to any broker's or finder's fee or any other commission or similar fee
in connection with any of the transactions contemplated by this Agreement except
Morgan Stanley & Co. Incorporated, whose fees and expenses will be paid by
Eclipsys in accordance with Eclipsys' agreement with such firm (a copy of which
has been delivered by Eclipsys to TSI prior to the date of this Agreement), and
BT Alex. Brown Incorporated whose fees and expenses will be paid by TSI in
accordance with TSI's agreement with such firm (a copy of which has been
delivered by TSI to Eclipsys prior to the date of this Agreement). Each of
Eclipsys and TSI agrees to indemnify and hold the other harmless from and
against any and all claims, liabilities or obligations with respect to any such
fees, commissions or expenses asserted by any person on the basis of any act or
statement alleged to have been made by such party or any of its Affiliates.

         Section 6.14 INDEMNIFICATION.

         (a) From and after the Effective Time, Eclipsys agrees that it will,
and will cause the Surviving Corporation to, indemnify and hold harmless each
present and former director and officer of TSI (the "Indemnified Parties"),
against any costs or expenses (including attorneys' fees), judgments, fines,
losses, claims, damages, liabilities or amounts paid in settlement
(collectively, "Costs") incurred in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of or pertaining to matters existing or occurring at
or prior to the Effective Time, whether asserted or claimed prior to, at or
after the Effective Time, to the fullest extent that TSI would have been
permitted under Massachusetts law and its articles of organization or bylaws in
effect on the date hereof to indemnify such Indemnified Party (and Eclipsys and
the Surviving Corporation shall also advance expenses as incurred to the fullest
extent permitted under applicable law, provided the Indemnified Party to whom
expenses are advanced provides an undertaking to repay such advances if it is
ultimately determined that such Indemnified Party is not entitled to
indemnification).

         (b) For a period of three (3) years after the Effective Time, Eclipsys
shall cause the Surviving Corporation to maintain (to the extent available in
the market) in effect a directors' and officers' liability insurance policy
covering those persons who are currently covered by TSI's directors' and
officers' liability insurance policy (a copy of which has been heretofore
delivered to Eclipsys) with coverage in amount and scope at least as favorable
as TSI's existing coverage; provided, that in no event shall Eclipsys or the
Surviving Corporation be required to expend in excess of 200% of the annual
premium currently paid by TSI for such coverage (currently $203,500),

                                     - 43 -


<PAGE>   52



except to the extent such excess is attributable to Eclipsys' claims history or
price increases in the market for such insurance that is unrelated to TSI
specifically; and if such premium would at any time exceed such limitation, the
Surviving Corporation shall maintain insurance policies that provide the maximum
and best coverage available at an annual premium equal to such limitation; and
provided further that, if any legal action had been pending at any time
subsequent to the second anniversary of the Effective Time against any person
currently covered by TSI's directors' and officers' liability insurance policy
that would be covered in whole or in part by such policy, the Surviving
Corporation shall thereafter continue to maintain such policy in effect (subject
to the foregoing proviso) until the fifth anniversary of the Effective Time.

         (c) The provisions of this Section 6.14 are intended to be in addition
to the rights otherwise available to the current officers and directors of TSI
by law, charter, statute, bylaw or agreement, and shall operate for the benefit
of, and shall be enforceable by, each of the Indemnified Parties, their heirs
and their representatives.

         Section 6.15 LETTER OF ECLIPSYS' ACCOUNTANTS. Eclipsys shall use
reasonable efforts to cause to be delivered to TSI and Eclipsys a letter of
PricewaterhouseCoopers LLP, Eclipsys' independent auditors, dated a date within
two business days before the date on which the Registration Statement shall
become effective and addressed to TSI, in form reasonably satisfactory to TSI
and customary in scope and substance for letters delivered by independent public
accountants in connection with registration statements similar to the
Registration Statement.

         Section 6.16 LETTER OF TSI'S ACCOUNTANTS. TSI shall use reasonable
efforts to cause to be delivered to Eclipsys and TSI letters of
PricewaterhouseCoopers LLP, TSI's independent auditors, and Ernst & Young,
HealthVISION's auditors, each dated a date within two business days before the
date on which the Registration Statement shall become effective and addressed to
Eclipsys, in form reasonably satisfactory to Eclipsys and customary in scope and
substance for letters delivered by independent public accountants in connection
with registration statements similar to the Registration Statement.

         Section 6.17 WARBURG REGISTRATION RIGHTS AGREEMENT. Eclipsys shall use
its reasonable efforts to amend its existing Second Amended and Restated
Registration Rights Agreement, dated January 1998, among Eclipsys and certain of
its stockholders (the "Registration Rights Agreement") (i) to add Warburg as a
"Designated Holder" (as defined in the Registration Rights Agreement) for all
purposes of the Registration Rights Agreement and (ii) to provide Warburg with
one demand registration pursuant to Section 3(a) of the Registration Rights
Agreement, which demands may not be exercised prior to January 1, 2000. In the
event Eclipsys is unable for any reason to amend the Registration Rights
Agreement as provided in the immediately preceding sentence, Eclipsys shall
enter into a registration rights agreement with Warburg, containing the
foregoing terms and otherwise substantially identical to the

                                     - 44 -

Registration Rights Agreement, except that the only Designated Holder therein
shall be Warburg (such agreement, either as the amendment to the Registration
Rights Agreement or the separate registration rights agreement, the "Warburg
Registration Rights Agreement").

party whose failure to fulfill any obligation under this Agreement has been the
cause of or resulted in the failure of the Merger to occur on or before such
date); or

         (c) by either Eclipsys or TSI if a court of competent jurisdiction or
other Governmental Entity shall have issued a nonappealable final order, decree
or ruling or taken any other nonappealable final action, in each case having the
effect of permanently restraining, enjoining or otherwise prohibiting the
Merger; or

         (d) by Eclipsys, if, at the TSI Stockholders' Meeting (including any
adjournment or postponement), the requisite vote of the stockholders of TSI in
favor of this Agreement and the Merger shall not have been obtained; or by TSI
if, at the Eclipsys Stockholders' Meeting (including any adjournment or
postponement), the requisite vote of the stockholders of Eclipsys in favor of
the Eclipsys Voting Proposals shall not have been obtained; or

         (e) by Eclipsys, if (i) the Board of Directors of TSI shall have
withdrawn or modified in a manner adverse to Eclipsys its recommendation of this
Agreement or the Merger; (ii) the Board of Directors of TSI shall have

Section 8.03(h)); (iii) a tender offer or exchange offer for 15% or more of the
outstanding shares of TSI Voting Common Stock is commenced (other than by
Eclipsys or an Affiliate of Eclipsys) and the Board of Directors of TSI
recommends that the stockholders of TSI tender their shares in such tender or
exchange offer; or (iv) for any reason (other than by reason of the Joint Proxy
Statement not having been cleared by the SEC) TSI fails to call and hold the TSI

terminate this Agreement under such clause (iv) shall not be available if at
such time TSI would be entitled to terminate this Agreement under Section
8.01(h)); or

         (g) by TSI, if the Board of Directors of TSI accepts or approves a
Superior Proposal, or recommends a Superior Proposal to the stockholders of TSI;
or

         (h) by Eclipsys or TSI, if there has been a breach of any
representation, warranty, covenant or agreement on the part of the other party
set forth in this Agreement, any of which breaches (i) causes the conditions set
forth in Section 7.02(a), (b), (e) or (f) (in the case of termination by
Eclipsys) or 7.03(a), (b) or (e) (in the case of termination by TSI) not to be
satisfied, and (ii) shall not have been cured within 20 business days following
receipt by the breaching party of written notice of such breach from the other
party.

         Section 8.02 EFFECT OF TERMINATION. In the event of termination of this
Agreement as provided in Section 8.01, this Agreement shall immediately become
void and there shall be no liability or obligation on the part of Eclipsys, TSI,
Sub or their respective officers, directors, stockholders or Affiliates, except
as set forth in Section 8.03; provided, that no such termination shall limit or
otherwise relieve the liability of any party for any breach of this Agreement
(except to the extent that liability may be limited by Section 8.03(c) or
Section 8.03(e) below); and provided further, that the provisions of Section
8.03 of this Agreement and the Confidentiality Agreement shall remain in full
force and effect and survive any termination of this Agreement.

         Section 8.03 FEES AND EXPENSES.

         (a) Except as set forth in this Section 8.03, all fees and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such expenses, whether or not the
Merger is consummated; provided, however, that TSI and Eclipsys shall share
equally all fees and expenses, other than attorneys' fees, incurred in relation
to the printing and filing of the Joint Proxy Statement (including any related
preliminary materials) and the Registration Statement (including financial
statements and exhibits) and any amendments or supplements.

         (b) TSI shall pay Eclipsys up to $2,000,000 as reimbursement for
expenses of Eclipsys actually incurred relating to the transactions contemplated
by this Agreement prior to termination (including, but not limited to, fees and
expenses of Eclipsys' counsel, accountants and financial advisors, but excluding
any discretionary fees paid to such financial advisors), upon the termination of
this Agreement by Eclipsys pursuant to Section 8.01(d) as a result of the
failure to receive the requisite vote for approval of this Agreement and the
Merger by the stockholders of TSI at the TSI Stockholders' Meeting, Section
8.01(e), Section 8.01(g) or Section 8.01(h) as a result of a breach by TSI of
any of the covenants set forth in any of Sections 5.01, 5.04, 6.01,

                                     - 49 -


<PAGE>   58



6.02, 6.03, 6.04, 6.05, 6.06, 6.07, 6.08, 6.09, 6.10, 6.16 or 6.18 of this
Agreement (collectively, the "TSI Material Covenants").

         (c)      TSI shall pay Eclipsys a termination fee of $9,100,000 upon 
the earliest to occur of the following events (each an "Eclipsys Termination Fee
Event"):

                  (i)      the termination of this Agreement by  Eclipsys
pursuant to Section 8.01(e); or

                  (ii)     the termination of this Agreement by Eclipsys
pursuant to Section 8.01(h) after a breach by TSI of any of the TSI Material
Covenants; or

                  (iii)    consummation of an Alternative Transaction with
respect to TSI within twelve (12) months following the failure to receive the
requisite vote for approval of this Agreement and the Merger by the stockholders
of TSI at the TSI Stockholders' Meeting if, at the time of such failure, any
Alternative Transaction relating to TSI had been announced and had not been
absolutely and unconditionally withdrawn and abandoned; or

                  (iv)     the termination of this Agreement by TSI pursuant to
Section 8.01(g).

Notwithstanding the foregoing, any amount payable pursuant to this Section
8.03(c) shall be reduced, on a dollar-for-dollar basis, by any amount
theretofore paid to Eclipsys pursuant to Section 8.03(b). TSI agrees that it
will not structure any transaction or agreement for the purpose of avoiding
payment of the termination fee required by this Section 8.03(c). TSI further
acknowledges that the agreements contained in this Section 8.03(c) are an
integral part of the transactions contemplated by this Agreement, and that,
without these agreements, Eclipsys would not enter into this Agreement;
accordingly, if TSI fails to promptly pay the amount due pursuant to this
Section 8.03(c), and, in order to obtain such payment, Eclipsys commences a suit
which results in a judgment against TSI for the fee set forth in this Section
8.03(c), TSI shall pay to Eclipsys its costs and expenses (including fees and
disbursements of counsel) in connection with such suit, together with interest
on the amount of the termination fee at the prime rate of Citibank, N.A. on the
date such payment was required to be made. Eclipsys and TSI further acknowledge
and agree that it may be difficult and impractical to measure in money the
damages which will accrue by reason of the occurrence of an Eclipsys Termination
Fee Event. Therefore, Eclipsys and TSI agree that payment of the termination fee
and any other fees, costs or expenses due under this Section 8.03(c) shall
constitute liquidated damages and not a penalty and shall further constitute the
sole and exclusive remedy of Eclipsys for any losses, damages, claims, costs or
expenses arising from the occurrence of any Eclipsys Termination Fee Event.

         (d)      Eclipsys shall pay TSI up to $2,000,000 as reimbursement for
expenses of TSI actually incurred relating to the transactions contemplated by
this Agreement prior to termination (including, but not limited to, fees and
expenses of TSI's counsel, accountants and financial advisors, but excluding any
discretionary fees paid to such financial advisors), upon the termination of
this Agreement by TSI pursuant to Section 8.01(d) as a result of the failure to
receive the requisite vote for approval of the Eclipsys Voting Proposals by the
stockholders of Eclipsys at the Eclipsys Stockholders' Meeting, Section 8.01(f)
or Section 8.01(h) as a result of a breach by Eclipsys of any of the covenants
set forth in Sections 5.02, 6.01, 6.03, 6.04, 6.05, 6.06, 6.07, 6.08, 6.09,
6.10, 6.11, 6.12, 6.15, 6.17 or 6.18 of this Agreement (collectively, the
"Eclipsys Material Covenants").

         (e)      Eclipsys shall pay TSI a termination fee of $9,100,000 upon
the earliest to occur of the following events (each a "TSI Termination Fee
Event"):

                  (i)      the termination of this Agreement by  TSI pursuant to
Section 8.01(f), or

                  (ii)     the termination of this Agreement by TSI pursuant to
Section 8.01(h) after a breach by Eclipsys of any of the Eclipsys Material
Covenants; or

                  (iii)    consummation of an Alternative Transaction with
respect to Eclipsys within twelve (12) months following the failure to receive
the requisite vote for approval of the Eclipsys Voting Proposals by the
stockholders of Eclipsys at the Eclipsys Stockholders' Meeting if, at the time
of such failure, any Alternative Transaction relating to Eclipsys had been
announced and had not been absolutely and unconditionally withdrawn and
abandoned.

Notwithstanding the foregoing, any amount payable pursuant to this Section
8.03(e) shall be reduced, on a dollar-for-dollar basis, by any amount
theretofore paid to TSI pursuant to Section 8.03(d). Eclipsys agrees that it
will not structure any transaction or agreement for the purpose of avoiding
payment of the termination fee required by this Section 8.03(e). Eclipsys
further acknowledges that the agreements contained in this Section 8.03(e) are
an integral part of the transactions contemplated by this Agreement, and that,
without these agreements, TSI would not enter into this Agreement; accordingly,
if Eclipsys fails to promptly pay the amount due pursuant to this Section
8.03(e), and, in order to obtain such payment, TSI commences a suit which
results in a judgment against Eclipsys for the fee set forth in this Section
8.03(e), Eclipsys shall pay to TSI its costs and expenses (including fees and
disbursements of counsel) in connection with such suit, together with interest
on the amount of the termination fee at the prime rate of Citibank, N.A. on the
date such payment was required to be made. Eclipsys and TSI further acknowledge
and agree that it may be difficult and impractical to measure in money the
damages which will accrue by reason of the occurrence of a TSI Termination Fee
Event. Therefore,

                                     - 51 -


<PAGE>   60



Eclipsys and TSI agree that payment of the termination fee and any other fees,
costs or expenses due under this Section 8.03(e) shall constitute liquidated
damages and not a penalty and shall further constitute the sole and exclusive
remedy of TSI for any losses, damages, claims, costs or expenses arising from
the occurrence of any TSI Termination Fee Event.

         (g) The expenses and fees, if applicable, payable pursuant to Section
8.03(b), 8.03(c), 8.03(d) and 8.03(e) shall be paid within one business day
after the first to occur of the events described in Section 8.03(b), 8.03(c),
8.03(d) or 8.03(e)(i), (ii) or (iii); provided that in no event shall Eclipsys
or TSI, as the case may be, be required to pay the expenses and fees, if
applicable, to the other, if, immediately prior to the termination of this
Agreement, the party to receive the expenses and fees, if applicable, was in
material breach of its obligations under this Agreement.

         (h) As used in this Agreement, "Alternative Transaction" means any of
(i) a transaction other than an Eclipsys Permitted Acquisition pursuant to which
any person (or group of persons) other than Eclipsys or TSI or their respective
affiliates (a "Third Party"), acquires more than 15% of the outstanding shares
of TSI Voting Common Stock or Eclipsys Voting Common Stock, as the case may be,
pursuant to a tender offer or exchange offer or otherwise, (ii) a merger or
other business combination involving Eclipsys or TSI other than an Eclipsys
Permitted Acquisition pursuant to which any Third Party acquires more than 15%
of the outstanding equity securities of Eclipsys or TSI or the entity surviving
such merger or business combination, (iii) any other transaction other than an
Eclipsys Permitted Acquisition pursuant to which any Third Party acquires
control of assets (including for this purpose the outstanding equity securities
of Subsidiaries of Eclipsys or TSI, and the entity surviving any merger or
business combination including any of them) of Eclipsys or TSI having a fair
market value (as determined by the Board of Directors of Eclipsys or TSI, as the
case may be, in good faith) equal to more than 15% of the fair market value of
all the assets of Eclipsys or TSI and its Subsidiaries, taken as a whole,
immediately prior to such transaction, or (iv) any public announcement of a
proposal, plan or intention to do any of the foregoing or any agreement to
engage in any of the foregoing.

         Section 8.04 AMENDMENT. This Agreement may be amended by the parties
hereto, by action taken or authorized by their respective Boards of Directors,
at any time before or after approval of the matters presented in connection with
the Merger by the stockholders of TSI or of Eclipsys, but, after any such
approval, no amendment shall be made which by law requires further approval by
such stockholders without such further approval. This Agreement may not be
amended except by an instrument in writing signed on behalf of each of the
parties hereto.

         Section 8.05 EXTENSION; WAIVER. At any time prior to the Effective
Time, the parties hereto, by action taken or authorized by their respective
Boards of Directors,

                                     - 52 -

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 contained herein or in any
document delivered pursuant hereto and (iii) waive compliance with any of the
agreements or conditions 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 a
written instrument signed on behalf of such party.

Time, except for the agreements contained in Sections 1.04, 2.01, 2.02, 6.12,
6.14, 8.03 and Article IX, and the agreements of the Affiliates delivered
pursuant to Section 6.10. The Confidentiality Agreement shall survive the

                                VOTING AGREEMENT

         VOTING AGREEMENT (the "Agreement"), dated as of October 29, 1998,
between __________________________ (the "Stockholder"), who is a stockholder of
Transition Systems, Inc., a Massachusetts corporation (the "Company"), and
Eclipsys Corporation, a Delaware corporation ("Buyer").

         WHEREAS, concurrently with the execution of this Agreement, the
Company, Buyer and a wholly-owned subsidiary of Buyer ("Sub") have entered into
an Agreement and Plan of Merger (as the same may be amended from time to time,
the "Merger Agreement"), providing for the merger (the "Merger") of Sub with and
into the Company pursuant to the terms and conditions of the Merger Agreement;
and

         WHEREAS, the Stockholder owns of record and beneficially the number of
shares of capital stock of the Company set forth beneath his signature below
(the "Shares") and wishes to enter into this Agreement with respect to all of
such Shares ; and

         WHEREAS, in order to induce Buyer to enter into the Merger Agreement,
the Stockholder has agreed, upon the terms and subject to the conditions set
forth herein, to vote the Shares and to deliver an irrevocable proxy to Buyer to
vote the Shares at a meeting of the Company's stockholders, in favor of approval
and adoption of the Merger Agreement and the Merger.

         NOW THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

         1. Agreement to Vote Shares. The Stockholder agrees during the term of
this Agreement to vote the Stockholder's Shares, in person or by proxy, in favor
of approval and adoption of the Merger Agreement and the Merger at every meeting
of the stockholders of the Company at which such matters are considered and at
every adjournment thereof. The Stockholder agrees to deliver to Buyer upon
request immediately prior to any vote contemplated by clause (a) or (b) above a
proxy substantially in the form attached hereto as Annex A (a "Proxy"), which
Proxy shall be irrevocable during the term of this Agreement to the extent
permitted under Massachusetts law, and Buyer agrees to vote the Shares subject
to each such Proxy in favor of approval and adoption of the Merger Agreement and
the Merger.

         2. No Voting Trusts. The Stockholder agrees that the Stockholder will
not, nor will the Stockholder permit any entity under the Stockholder's control
to, deposit


                                      A-1-1


<PAGE>   66



any of the Stockholder's Shares in a voting trust or subject any of its Shares
to any arrangement with respect to the voting of the Shares inconsistent with
this Agreement.

         3. Limitation on Dispositions and Proxies. During the term of this
Agreement, the Stockholder agrees not to sell, assign, pledge, transfer or
otherwise dispose of, or grant any proxies with respect to (except as
contemplated by this Agreement) any of the Stockholder's Shares.

         4. Specific Performance. Each party hereto acknowledges that it will be
impossible to measure in money the damage to the other party if a party hereto
fails to comply with the obligations imposed by this Agreement, and that, in the
event of any such failure, the other party will not have an adequate remedy at
law or in damages. Accordingly, each party hereto agrees that injunctive relief
or other equitable remedy, in addition to remedies at law or damages, is the
appropriate remedy for any such failure and will not oppose the granting of such
relief on the basis that the other party has an adequate remedy at law. Each
party hereto agrees that it will not seek, and agrees to waive any requirement
for, the securing or posting of a bond in connection with any other party's
seeking or obtaining such equitable relief.

         5. Term of Agreement; Termination. Subject to Section 9(e), the term of
this Agreement shall commence on the date hereof and such term and this
Agreement shall terminate upon the earliest to occur of (i) the Effective Time
(as defined in the Merger Agreement), and (ii) the date on which the Merger
Agreement is terminated in accordance with its terms. Upon such termination, no
party shall have any further obligations or liabilities hereunder; provided,
that such termination shall not relieve any party from liability for any breach
of this Agreement prior to such termination.

         6. Representations and Warranties of the Stockholder. The Stockholder
represents and warrants to Buyer that, as of the date hereof, (a) the
Stockholder has full legal power and authority to execute and deliver this
Agreement and the Proxy, and (b) the Stockholder's Shares are free and clear of
all proxies.

         7. Entire Agreement. This Agreement supersedes all prior agreements,
written or oral, among the parties hereto with respect to the subject matter
hereof and contains the entire agreement among the parties with respect to the
subject matter hereof. This Agreement may not be amended, supplemented or
modified, and no provisions hereof may be modified or waived, except by an
instrument in writing signed by all parties hereto. No waiver of any provisions
hereof by any party shall be deemed a waiver of any other provisions hereof by
any such party, nor shall any such waiver be deemed a continuing waiver of any
provisions hereof by such party.

         8. Notices. All notices, requests, claims, demands or other
communications hereunder shall be in writing and shall be deemed given when
delivered personally, upon receipt of a transmission confirmation if sent by
facsimile or like transmission
