including the EPSI Stock Issuance.

(a) At least one Business Day prior to the Closing Date, the Stockholders shall deliver to Eclipsys the Stockholders good faith

(i) The Current Assets,
the Current Liabilities, the Closing Date Net Working Capital and the Estimated Closing Date Net Working Capital, the Closing Date Debt and the Estimated Closing Date Debt, the Closing Date Cash and the Estimated Closing Date Cash shall be
calculated, as applicable (A) consistent with the hypothetical calculation of the Closing Date Net Working Capital and Purchase Price set forth in Schedule 2.3; (B) in conformity with GAAP; (C) consistent with the practices and

---

(ii) For purposes of calculating the Current Assets, the Current Liabilities, the Closing
Date Net Working Capital, the Estimated Closing Date Net Working Capital, the Closing Date Debt and the Estimated Closing Date Debt, such calculation shall not take into account (A) the impact of any purchase accounting adjustments relating to
Eclipsys acquisition of EPSI, including any write-up or write-down of assets or liabilities resulting from such purchase accounting, or (B) any Seller Transaction Costs unpaid as of the Closing Date provided such costs are paid within the
60 day period set forth in Section 2.3(a)(iv).

(iii) Within one Business Day after receipt of the
Stockholders estimated Closing Date Net Working Capital, Closing Date Cash and Closing Date Debt, Eclipsys shall provide the Stockholders Representative with Eclipsys written comments thereto, and the Stockholders shall in good
faith consider any such comments.

(A) For purposes of payment on the Closing Date of the Closing Payment, the amounts
thereof shall be calculated based on the Stockholders estimated Closing Date Cash and Closing Date Debt, each as modified pursuant to this paragraph, if applicable (such estimate, as applicable, the Estimated Closing Date
Cash and the Estimated Closing Date Debt), but shall be subject to adjustment post-Closing as set forth in Sections 2.3(f) and (g) if there is a variance between (1) the Estimated
Closing Date Cash and the Closing Date Cash, or (2) the Estimated Closing Date Debt and the Closing Date Debt.

(B)

Closing Date Net Working Capital, as modified pursuant to this paragraph, if applicable, is referred to herein as the Estimated Closing Date Net Working Capital.

(iv) The Stockholders shall bear the cost of the Seller Transaction Expenses, and the Stockholders shall pay such expenses in full on or
before the Closing Date, or within 60 days thereafter, and if paid prior to the Closing Date or within such 60 day period thereafter, shall not be included in Current Liabilities for purposes of calculating the Closing Date Net Working Capital.
Without limiting the rights of Eclipsys and the other Eclipsys Indemnified Parties hereunder, including the rights of indemnification set forth in Article VII, the Stockholders shall immediately indemnify Eclipsys and EPSI and any other
Eclipsys Indemnified Party, to the extent such Persons shall be obligated to pay any of the Seller Transaction Costs, and to the extent such costs are not paid within the 60 day period set forth in this clause (iv), notwithstanding anything
contained herein to the contrary, such Persons may elect, in their discretion, to recover under this clause (iv), rather than treat any such costs as Current Liabilities.

binding on the parties if an Acceptance Notice is delivered to Eclipsys or if no Objection Notice is delivered to Eclipsys with respect to such amounts within the 30 day period required by Section 2.3(d). If an Objection Notice is
delivered, the potential dispute with respect to the Closing Date Net Working Capital, the Closing Date Cash or the Closing Date Debt shall be resolved as set forth in Section 2.4, and the Closing Date Net Working Capital, the Closing
Date Cash or the Closing Date Debt, to the extent in dispute, determined pursuant to such procedures, in addition to the undisputed amounts, shall be final and binding on the parties.

(f) Upon determination of the Closing Date Net Working Capital, the Closing Date Cash and the Closing Date Debt pursuant to

respect to the objection. If Eclipsys and the Stockholders Representative are unable to reach agreement within 15 days after an Objection Notice has been given, any unresolved disputed items shall be promptly referred to the Los Angeles
office of Deloitte and Touche USA LLP; provided, however, if such firm is unavailable or if either of the parties has used the services of Deloitte and Touche USA LLP (or its Affiliates) at any time in the twelve month period before the date
the Objection Notice is given, then the unresolved items shall be promptly referred to such other



14



---

nationally recognized independent accounting firm mutually agreed to by Eclipsys and the Stockholders Representative (Deloitte and Touche USA LLP, or
such other firm, the Unrelated Accounting Firm). The Unrelated Accounting Firm shall be directed to render a written report on the unresolved disputed issues as promptly as practicable (but in no event later than 45 days
following submission of the matter to the Unrelated Accounting Firm) and to resolve only those issues of dispute set forth in the Objection Notice (subject to any items resolved by the parties after consultation pursuant to the first sentence of
this Section 2.4). In resolving any disputed issues relating to the Closing Date Net Working Capital, the Closing Date Cash or the Closing Date Debt, the Unrelated Accounting Firm shall act as experts and not as arbitrators. The
resolution by the Unrelated Accounting Firm of the disputed amount, and the undisputed amounts, shall be final and binding on the parties for purposes of determining the Closing Date Net Working Capital, the Closing Date Cash and the Closing Date
Debt, and the amounts owed by the parties under Sections 2.3(f) and (g), if any. The percentage of the expenses of the Unrelated Accounting Firm that shall be borne by the Stockholders on the one hand (in their Pro Rata Portion), and
Eclipsys on the other hand, shall be the same as the percentage of the amount in dispute that the Unrelated Accounting Firm shall determine the other party is entitled to receive, with the Stockholders paying the entire amount of the expenses of the
Unrelated Accounting Firm if the Unrelated Accounting Firm determines Eclipsys to be correct in its determination, in the aggregate, of the Closing Date Net Working Capital, the Closing Date Cash and the Closing Date Debt, and Eclipsys paying the
entire amount of the expenses of the Unrelated Accounting Firm if the Unrelated Accounting Firm determines the Stockholders to be correct, in the aggregate, in their determination of the Closing Date Net Working Capital, the Closing Date Cash and
the Closing Date Debt. The parties shall promptly pay such amounts to the Unrelated Accounting Firm.

2.5 Closing.

to the nearest whole number). For this purpose, the Restricted Stock Factor for each Employee Grantee is set forth in Schedule 2.1; provided that if any such person shall not become an Employee Grantee on the Closing Date, each Employee
Grantees Restricted Stock Factor will be proportionately increased to reallocate among the Employee Grantees the Restricted Stock Factor of the person who did not become an Employee Grantee; provided further that if any person shall become an

the Nasdaq stock market on the Business Day prior to the date of such determination.

Off-the-Shelf Software) in sufficient quantities and of sufficient scope to cover all of EPSIs past and current use(s) and copies of the Company Licensed IP and those reasonably anticipated to be needed (y) for internal use during the
year after the Closing Date in accordance with current business plans, and (z) for the duration of the terms (including during any periods subject to a renewal right) of any Contract with or binding on EPSI or its properties pursuant to which
Company Licensed IP is used by third parties. Furthermore, the rights licensed under each License-In Agreement shall be exercisable by EPSI on and after the Closing Date to the same extent and at the same cost as EPSI had prior to the Closing Date,
and no Person granting rights under any License-In Agreement has given notice in writing, or such other form as permitted by such License-In Agreement, to the Stockholders or EPSI or, to the Knowledge of EPSI, Threatened that it intends to terminate
such License-In Agreement prior to the expiration of the existing term thereof or to deny any request for an extension of such term.

(ii) EPSI has the right to enforce the Company Owned IP against the Stockholders and third parties. EPSI is not, and will not with the passage of time or satisfaction of conditions become, obligated to make any payment to any Person in
connection with the manufacture, use, sale, importation, distribution, display, modification or other exploitation of any Company Owned IP or Software Products. EPSI is free to make, use, modify, copy, distribute, sell, license, import, export and
otherwise exploit all Company Owned IP on an exclusive basis subject only to nonexclusive (x) use pursuant to end-user licenses granted to customers; (y) distribution rights granted to the resellers or distributors listed in
Section 4.14(c) of the Stockholders Disclosure Schedule; and (z) nondisclosure or confidentiality agreements pursuant to which any Person has been granted access to Company Owned IP but in which such agreement does not grant
the right to exploit such Company Owned IP; in each case of (x) through (z) in the ordinary course of business consistent with past practice and disclosed to Eclipsys prior to the date hereof. No current or former employee, officer,
director, stockholder, consultant or independent contractor of EPSI has any valid right, claim or interest in or with respect to any Company IP which would impair or which could give rise to the impairment of the use, distribution, license or other
exploitation of the Company IP by EPSI or Eclipsys or their transferees.

(d) EPSI has taken reasonable measures and
precautions to protect, preserve and maintain the confidentiality and secrecy of all trade secrets and other confidential information material to the Business, including at a minimum (i) maintaining the security of its facilities and systems so
that confidential information and trade secrets are not available to



32



---

Persons who are not authorized to have access; (ii) policing the use of such information; and (iii) taking appropriate action to address any
misuse, or compromise of the confidentiality of such information. None of the Stockholders or EPSI has disclosed or delivered or has permitted to be disclosed or delivered to any Person, and no Person (other than employees of EPSI who need such
information in the course of their employment) has access to or has any rights with respect to, trade secrets and other confidential or proprietary information material to the Business, the source code or any portion or aspect of the source code
related to the Software Products or otherwise material to the Business, or any proprietary information or algorithm contained in any source code related to the Software Products or of any other Software that comprises Company Owned IP, other than
instances where such trade secrets, confidential information and source code has been disclosed subject to an agreement with any Person pursuant to which such Person is required to maintain, and to the Knowledge of EPSI has not breached, the
confidentiality thereof. Without limiting the generality of the foregoing, EPSI has consistently (A) required each Person who has contributed to, or participated in the creation or development of any of the Software Products or other Company
Owned IP to execute and deliver to EPSI an agreement, in the form of Section 4.14(d)(i) of the Stockholders Disclosure Schedule, or another form provided to Eclipsys prior to the date hereof, assigning all rights in the Software
Products and other Company Owned IP, and all such agreements are in full force and effect, and (B) marked confidential or trade secret materials as such prior to disclosure of such materials to any third party. EPSI does not have any source
code, or any portion or aspect of source code, currently maintained in escrow, and no customer or other Person entitled to require source code, or any portion thereof, to be delivered to escrow has requested such a delivery to escrow or requested
delivery directly to such customer or other Person in connection with or in lieu of such escrow arrangement. Section 4.14(d)(ii) of the Stockholders Disclosure Schedule sets forth all Software escrow Contracts relating to the
Software Products or any other Software that comprises Company Owned IP and the parties to such escrow Contracts. True, complete and accurate copies (or, as to oral Contracts, written summaries of the terms) of all such escrow Contracts have been
provided to Eclipsys.

(e) (i) None of the Company Owned IP or any of the products or services of EPSI or the Intellectual
Property used by EPSI in its operations that is not Company Licensed IP, infringe, misappropriate, violate, dilute or constitute the unauthorized use of any Intellectual Property of any third party and none of the Stockholders or EPSI has received
(A) any written notice or claim in the past six (6) years, and no Person has Threatened during such period to provide a notice or claim alleging or asserting that any such infringement, misappropriation, violation, dilution or unauthorized
use is or may be occurring or has or may have occurred, or (B) any written notice or claim alleging or asserting that any such infringement, misappropriation, violation, dilution or unauthorized use is or may be occurring or has or may have
occurred. No confidential information or invention owned by any former employer of any current or former employee or consultant of EPSI is incorporated into, used or relied upon in the products or services of EPSI. There is not any pending claim or
demand which challenges the ownership, legality, validity, enforceability, use, exploitation or modification by EPSI of such Company Owned IP or any of the products or services of EPSI or the Intellectual Property used by EPSI in its operations
which is not Company Licensed IP, and to the Knowledge of EPSI no such claim or demand is threatened and no facts or circumstances



33



---

exist that could reasonably be expected to result in such a claim or demand. No Company Owned IP or any of the products or services of EPSI or the
Intellectual Property used by EPSI in its operations which is not Company Licensed IP, is subject to any outstanding Order restricting the use thereof by EPSI or, in the case of any Intellectual Property licensed to others, restricting the sale,
transfer, assignment or licensing thereof by EPSI to any Person.

(ii) To the Knowledge of EPSI, the use by EPSI of the
Company Licensed IP does not infringe, misappropriate, violate, dilute or constitute the unauthorized use of any Intellectual Property of any other Person.

(iii) EPSI has the right to grant the licenses it grants in the course of its business.

(iv) EPSI has the right to conduct its business as it is currently conducted.

(v) The Company IP held by EPSI:
(A) constitutes all of the Intellectual Property used in or necessary for the conduct of the Business; and (B) constitutes all of the Intellectual Property necessary to operate such Business after the Closing in substantially the same
manner as the Business has heretofore been operated by EPSI. No rights in any Intellectual Property other than the Company IP are necessary to avoid infringing any intellectual property or other legal or contractual right of any Person in the
conduct of the Business as currently or previously conducted, or as currently contemplated by EPSI.

(f) All Company
Registered IP is (i) valid, enforceable to the full extent permitted by the jurisdiction in which it is registered and in full force and effect, and (ii) all maintenance, annuity and other fees due in respect of such Company Registered IP
have been fully paid and all filings applicable thereto have been properly made. No trademark included in the Company Registered IP is now involved in any opposition or cancellation proceeding and no trademark that is currently used by EPSI has been
involved in any opposition or cancellation proceeding. No patent or patent application included in the Company Registered IP is now involved in any interference, reissue or reexamination proceeding.

(g) To the Knowledge of EPSI, no Person is infringing or misappropriating any Company Owned IP in any material respect or making any
unlawful use of any products of EPSI in any material respect. None of the Stockholders or EPSI (including its representatives) has given notice to any Person in the last three years of any such infringement, misappropriation or unlawful use or
alleged infringement, misappropriation or unlawful use. EPSI has not initiated nor is it maintaining before a court or in an arbitration proceeding claims or causes of action against other Persons for infringement or misappropriation by such Persons
of Company Owned IP (including claims for past infringement or misappropriation of Intellectual Property). EPSI has not, during the last twelve months, threatened in a writing sent by the legal counsel of EPSI to initiate such proceeding.

(h) No Company IP, incorporated into or used in conjunction with any product, system,
program or Software that is or was used in or that relates to the assets of EPSI contains any back door, time bomb, Trojan horse, worm, drop dead device, virus or other software
routines or hardware components designed to permit unauthorized access or to disable or erase software, hardware or data without the consent of the user.

(i) The existing and currently manufactured and marketed products of EPSI have the features and perform the functions described in (i) any agreed specifications, responses to requests for proposals or end user
documentation, provided to customers or potential customers of EPSI, and (ii) any Contracts or representations made by EPSI or its representatives (either orally or in writing) that such customers or potential customers could reasonably rely on
in deciding to purchase the products (notwithstanding any subsequent disclaimer of any representations or warranties) or would reasonably be expected to rely upon when licensing or otherwise acquiring such products, in each case, subject to
subsequent changes expressly requested by the customer, and neither the Stockholders nor EPSI has received any notice or complaints alleging that such products do not perform as so described. EPSI has performed all material obligations (legal and
contractual) required to be performed by it under the Contracts with customers and it is not (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect thereunder, and, with respect to material
obligations required to be performed under such Contracts that are not yet due, there is no reason to expect that such obligations will not be fulfilled when they become due.

(j) No Company Owned IP is, in whole or in part, subject to the provisions of any open source, quasi-open source or other source code
license agreement that (i) requires the distribution of source code in connection with the distribution of the licensed software in object code form; (ii) prohibits or limits EPSI or any Affiliate from charging a fee or receiving
consideration in connection with sublicensing or distributing such licensed software (whether in source code or object code form); or (iii) allows a customer or requires that a customer have the right to decompile, disassemble or otherwise
reverse engineer the software by its terms and not by operation of law, including without limitation, any version of any of the following: (A) GNUs General Public License (GPL) or Lesser/Library GPL, (B) The

Community Source License, (G) an Open Source Foundation License (e.g., CDE and Motif UNIX user interfaces), and (H) the Apache Server license.

(k) EPSI has taken all reasonable actions to document any Software and its operation that is part of the Company IP, such that the materials comprising the Software, including the source code and documentation, have
been written in a clear and professional manner so that they may be understood, modified and maintained in an efficient manner by reasonably competent programmers and comply with all applicable contractual requirements.

(l) EPSI has not exported or transmitted Software, trade secrets or any other technical information, including any technical data, or the
direct product of such data, to or in any country to which such export or transmission or creation is restricted by any applicable Legal Requirement, without first having obtained all necessary and appropriate United States or other Government
Entity Permit(s). Section 4.14(l) of the Stockholders Disclosure Schedule

Software Product or other Software the modules upon which such subroutines operate and the type of encryption employed with respect to each such module.

(m) Without limiting the foregoing, the Software Products are wholly-owned by EPSI and none of the Stockholders has any rights or interests therein.

(n) The sole shareholders of CPM are, and at all times have been, the Stockholders. CPM has not engaged in any business activities, other
than initial sales activities, not resulting in any sales or licenses, and has not made any derivative works from, or, excluding its agreement with EPSI, entered into any Contract related to, the Software Products or any other Company Owned IP.

(o)(i) Each Contract relating to Company IP, other than licenses of Software Product to customers in the ordinary
course of business consistent with past practice (each, a Company IP Contract) is valid, binding and in full force and effect and is enforceable by EPSI in accordance with its terms, subject to applicable bankruptcy,
insolvency, moratorium, fraudulent conveyance, reorganization or other similar laws relating to creditors rights and general principles of equity, whether at equity or at law; (ii) EPSI has performed all material obligations required to
be performed by it under the Company IP Contracts and it is not (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect thereunder; and (iii) to the Knowledge of EPSI, no other party to
any of the Company IP Contracts is (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect thereunder. True, complete and accurate copies (or, as to oral Contracts, written summaries of the
terms) of the Company IP Contracts entered into on or prior to the date hereof have been provided to Eclipsys and true, complete and accurate copies (or, as to oral Contracts, written summaries of the terms) of any Company IP Contracts entered into
after the date hereof will be provided to Eclipsys promptly after being so entered into.

(p) Neither the execution and
delivery by the Stockholders of this Agreement and the other Transaction Documents, nor the consummation by Stockholders of the transactions contemplated herein and therein in accordance with the terms hereof and thereof, will violate, or conflict
with, or result in a breach of any provision of, or constitute a material default (or an event that, with notice or lapse of time or both, would constitute a breach or default) under, or result in the termination or in a right of termination or
cancellation of, or accelerate the performance required by, or result in the triggering of any payment obligations under, or result in the creation of any Lien upon any of the material properties of EPSI, or result in being declared void, voidable,
or without further binding effect, any of the provisions of any Company IP Contract.

(q) The Software Products will, in
their intended and ordinary use, not cause the violation of any applicable Legal Requirements restricting the collection, use, retention or distribution of personally identifiable information, including without limitation the Health Insurance

each continuing employee of EPSI with EPSI prior to the Closing Date for purposes of vesting and eligibility to participate (but not benefit accrual) under the employee benefit plans and policies of Eclipsys; provided, however, that
such service will not be recognized if recognition would result in a duplication of benefits for the same period of service or to the extent that such service was not recognized under the corresponding Company Benefit Plan.

(b) Nothing contained in this Agreement confers upon any employee of EPSI any right to continued employment or participation in any
Company Benefit Plan or any employee benefit plan or policy of Eclipsys at any time after the Closing Date, nor shall anything contained herein be deemed an amendment or modification of any Company Benefit Plan or any employee benefit plan or policy

heirs, successors and assigns, hereby irrevocably and unconditionally releases, acquits and forever discharges EPSI, Eclipsys, each of their respective Affiliates and their respective partners, stockholders, directors, officers and agents, and their

controversies, damages, actions, causes of action, suits, rights, demands, remedies, costs, losses, debts, expenses and fees, of every type, kind, nature, description or character, whether known or unknown, suspected or unsuspected, liquidated or

other assets or properties of EPSI, or (iii) the Stockholders right to or any interest in any Contract with EPSI, and (iv) any equity or other interests the Stockholder may have or claim to have in, or any other claims the
Stockholder may have against, EPSI or its predecessors (collectively, the Claims), other than one months salary and other expenses related to the employment of the Stockholders by EPSI that are accrued on the balance
sheet of EPSI as of the Closing Date, and included in the Current Liabilities and the Closing Date Net Working Capital calculation. Each Stockholder represents that he has not assigned or transferred or purported to have assigned or transferred to
any Person any Claims. This general release set forth in this Section 6.12 shall not affect any rights that the Stockholder may have which arise solely under this Agreement (including payment of the Purchase Price), or his Employment
Agreement or Restricted Stock Agreement, or that arise after the Closing Date.

(b) Each Stockholder acknowledges and agrees
that the releases made herein constitute final and complete releases of the Released Parties with respect to all Claims. Each Stockholder expressly acknowledges and agrees that this general release is intended to include in its effect, without
limitation, all Claims which such Stockholder does not know or suspect to exist at the time hereof, and this general release contemplates the extinguishment of any and all such Claims. Furthermore, each Stockholder hereby expressly waives and
relinquishes any rights and benefits he may have under any Legal Requirements, including Missouri state law or any common law principles limiting waivers of unknown claims. Each Stockholder understands that the facts under which he gives this full
and complete release and discharge of the Released Parties may hereafter prove to be different than now known or believed by him and such



45



---

Stockholder hereby accepts and assumes the risk thereof and agrees that his full and complete release and discharge of the Released Parties with respect to
the Claims shall remain effective in all respects and not be subject to termination, rescission or modification by reason of any such difference in facts and circumstances.

(c) Each Stockholder represents and agrees that he has not filed with any Governmental Entity or arbitrator or any other Person any
complaint, charge or lawsuit against any of the Released Parties involving any Claims, and that he will not do so at any time hereafter.

(d) Each Stockholder represents and acknowledges that in executing this general release he does not rely and has not relied upon any representation or statement not set forth herein made by any of the Released Parties
or by any of the Released Parties Affiliates, agents, representatives or attorneys with regard to the subject matter, basis or effect of this general release or otherwise.

(e) Without limiting the foregoing general release, each Stockholder agrees that he will not, directly or indirectly, (i) bring or
cause to be brought, or encourage or participate in the prosecution of, any action, proceeding or suit seeking recovery by or on behalf of any Person from any Released Party of any amount in respect of, or Damages with respect to, any of the Claims,
or (ii) defend any action, proceeding or suit in whole or in part on the grounds that any or all of the terms or provisions of this Section 6.12 are illegal, violate any Legal Requirements, invalid, inequitable, not binding,
unenforceable or against public policy.

6.13 Confidentiality.

(a) Each party and such partys representatives shall use any Confidential Information of any other party solely for the purpose of
pursuing the transactions contemplated hereby, and shall not directly or indirectly use or exploit the Confidential Information of any other party for its own benefit or the benefit of another Person, including to create, adopt or modify products or
services which would compete with the disclosing partys products or services. For purposes of this Agreement, Confidential Information of Eclipsys shall, from and after the Closing Date, include the Confidential Information of EPSI and the
Business. It is acknowledged that the parties are in related businesses and this provision is not intended to restrict their independent development efforts or other independent business activities, in each case undertaken without use of the other
partys Confidential Information.

(b) Each party agrees that (i) the Confidential Information of any other party
received or otherwise held by it or generated by it or its representatives based upon such Confidential Information shall be kept confidential, (ii) except as permitted hereunder, such party and its advisors and other representatives will not
disclose any of the Confidential Information of any other party in any manner whatsoever, and (iii) such party and its representatives will use the same level of care to prohibit disclosure of the other partys Confidential Information as
such party uses to protect its own confidential information, but in no event using less than reasonable care and diligence; provided, however, that (A) such party may make any disclosure of such information to which the other party gives
its prior written consent, and (B) any of such information may be disclosed to such partys representatives who need to know such information



46



---

for the sole purpose of pursuing the transactions contemplated hereby, and who agree to keep such information confidential. In any event, each party shall be
responsible for any breach of this Agreement by its representatives and shall, at its sole expense, take all reasonable measures (including but not limited to court proceedings) to restrain its representatives from prohibited or unauthorized
disclosure or use of the Confidential Information of any other party.

(c) The receiving party shall immediately notify the
other party upon any loss or unauthorized disclosure of the other partys Confidential Information.

(d) In the event
that any party or any of its representatives are requested or required (by oral questions, interrogatories, requests for information or documents in legal proceedings, subpoena, civil investigative demand or other similar process) to disclose any of
the Confidential Information of any other party, it shall provide the disclosing party with prompt written notice of any such request or requirement so that the disclosing party may seek a protective order or other appropriate remedy and/or waive
compliance with the provisions of this Agreement. If, in the absence of a protective order or other remedy or the receipt of a waiver by the disclosing party, the receiving party or any of its representatives are nonetheless, in the opinion of its
outside counsel, legally compelled to disclose Confidential Information of the disclosing party to any tribunal or else stand liable for contempt or suffer other similar censure or penalty, the receiving party or its representative may, without
liability hereunder, disclose to such tribunal only that portion of the Confidential Information of the disclosing party that such counsel advises is legally required to be disclosed, provided that the receiving party exercises its commercially
reasonable efforts to preserve the confidentiality of such Confidential Information, including, without limitation, by cooperating with the disclosing party to obtain an appropriate protective order or other reliable assurance that confidential
treatment will be accorded such Confidential Information by such tribunal.

(e) Each party acknowledges that the
Confidential Information of the other parties has tangible value and it is further understood and agreed that money damages would not be a sufficient remedy for any breach of the provisions set forth herein by any party or any of their
representatives and that the parties hereto shall be entitled to equitable relief, including injunction and specific performance, as a remedy for any such breach or threatened breach. Such remedies shall not be deemed to be the exclusive remedies
for a breach of the provisions set forth herein, but shall be in addition to all other remedies available at law or equity to the parties.

6.14 Covenants Regarding Contracts. On or before the Closing Date, EPSI shall obtain, unless waived by Eclipsys, all Consents required under the Material Contracts in connection with the execution, delivery and performance of this
Agreement, the other Transaction Documents or the consummation of the transactions contemplated hereby and thereby, on terms that are not materially burdensome to Eclipsys or EPSI.

6.15 Tax Matters.

(a) After the Closing, the Stockholders and Eclipsys shall each assist the other, and Eclipsys shall cause EPSI to assist the Stockholders, as may reasonably be requested by any of them with the preparation of any Tax Return, any Tax audit,
or any judicial or administrative proceedings relating to any Tax. In addition, each party shall retain and provide the other with any records or information that may be relevant to such Tax Return, Tax audit, proceeding or determination.



47

(b) EPSI and the Stockholders shall not revoke EPSIs election to be taxed as an S
corporation within the meaning of Code Sections 1361 and 1362. EPSI and the Stockholders shall not take or allow any action that would result in the termination of EPSIs status as a validly electing S corporation within the meaning of Code
Sections 1361 and 1362.

(c) Section 338(h)(10) Election.

(i) At Eclipsys option, the Stockholders shall join with Eclipsys in making an election under Section 338(h)(10) of the Code
(and any corresponding elections under state, local or foreign tax law) with respect to the purchase of the stock of EPSI hereunder (collectively, a Section 338(h)(10) Election).

(ii) If a Section 338(h)(10) Election is made, Eclipsys shall be responsible for the preparation and filing of all forms and
documents required in connection with the Section 338(h)(10) Election. For the purpose of making the Section 338(h)(10) Election, Eclipsys and the Stockholders shall execute Internal Revenue Service Form 8023 (or any successor form) and
any other forms required by applicable Legal Requirements. The Stockholders shall execute (or cause to be executed) and deliver to Eclipsys such additional documents or forms as requested by Eclipsys in order to make the Section 338(h)(10)
Election. The Stockholders shall include any income, gain, loss, deduction or other Tax item resulting from the Section 338(h)(10) Election on their Tax Returns to the extent required by applicable Legal Requirements. The Stockholders shall be
responsible for the payment of any Tax imposed on EPSI that is attributable to the making of the Section 338(h)(10) Election, including (i) any Tax imposed under Code section 1374 and (ii) any other federal, state or local Tax imposed
on EPSI and will indemnify and hold Eclipsys and EPSI harmless from any adverse consequences arising out of any failure to pay such Tax.

(iii) Eclipsys and the Stockholders agree that the Purchase Price and the liabilities of EPSI (plus other relevant items) will be allocated to the assets of EPSI for all purposes (including Tax and financial
accounting purposes) in a manner consistent with the fair market values set forth in Schedule 6.15(c) attached hereto (the Allocation Schedule). Eclipsys, EPSI and the Stockholders shall file all Tax Returns
(including amended Tax Returns and claims for refund) in a manner consistent with such Allocation Schedule.

(iv) If a
Section 338(h)(10) Election is made, Eclipsys agrees to increase the Purchase Price by an amount (the Gross-Up Amount) determined in accordance with this Section 6.15(c)(iv). The Gross-Up Amount, on an
after-tax basis, shall equal the sum of the following: (i) the transfer, documentary, sales, use and other similar taxes and fees payable by EPSI (Transfer Taxes) that result from making the Section 338(h)(10)
Election to the extent such Transfer Taxes exceed the Transfer Taxes that would have been imposed if the Section 338(h)(10) Election were not made; (ii) the product of (x) twenty percent (20%), and (y) the amount of gain realized
by EPSI with



48



---

respect to making the Section 338(h)(10) Election that is characterized as ordinary income rather than capital gain; and (iii) the amount of any
state and federal income tax imposed on EPSI under Code Section 1374 (or similar provisions of state law) on the gain resulting from the Section 338(h)(10) Election, but only to the extent the amount of gain subject to tax under Code
Section 1374 is disclosed on the Stockholders Disclosure Schedule. Within thirty (30) days following the date the parties reach final agreement on the allocations on Form 8883, the Stockholders (or the Stockholders
Representative) shall provide Eclipsys with written notice setting forth a computation of the Gross-Up Amount (plus all supporting computations). Within fifteen (15) days following receipt of the written notice by Eclipsys, Eclipsys shall pay
the Gross-Up Amount or notify the Stockholders (or the Stockholders Representative) of any dispute with the computation and the basis for such dispute. The parties shall act in good faith to resolve any such dispute within fifteen
(15) days, and if the parties cannot resolve the dispute within such time period then the dispute shall be resolved by the Unrelated Accounting Firm. The fees and expenses of the Unrelated Accounting Firm shall be borne equally by the
Stockholders and Eclipsys. Eclipsys shall pay the Gross-Up Amount within fifteen (15) following the resolution of any dispute.

(v) For the purpose of determining the Gross-Up Amount in accordance with Section 6.15(c)(iv), after-tax basis means that the Gross-Up Amount will include an additional amount to make the Stockholders whole for the
net amount of additional Taxes payable as a result of the receipt or accrual of the Gross-Up Amount and such additional payment (taking into account all available credits and deductions attributable to the payment or accrual of such additional
Taxes). In calculating the Gross-Up Amount, the Tax rates used shall be the highest marginal Tax rates actually applied to the Gross-Up Amount received by the Stockholders on the date of such payment or accrual. The after-tax basis portion of the
Gross-Up Amount shall be calculated by dividing the initial Gross-Up Amount by one minus the Stockholders marginal Tax rate determined in the preceding sentence (that is, initial Gross-Up Amount/(1  marginal Tax rate)).

6.16 CPM. Prior to the Closing, the Stockholders shall, at their expense, cause the Software License Agreement between EPSI and CPM to be
terminated and CPM and its contractor to enter into a release of EPSI and Eclipsys in the form attached hereto as Exhibit D, or another form that releases all claims such Persons may have against EPSI or Eclipsys.

ARTICLE VII

INDEMNIFICATION; REMEDIES

7.1 Survival of Representations and Warranties and Covenants.

(a) The representations and warranties made in this Agreement shall survive for eighteen months after the Closing Date (the
Survival Period). Notwithstanding the foregoing, the representations and warranties set forth in Sections 3.1, 3.3, 4.3, 4.9, 4.10, 4.11(b), 4.14 (but excluding
subsections (i), (o), (p) and (q) of said Section 4.14), 4.15(a), 4.16, 4.23, 5.3 and 5.4 shall survive until 30 days after the expiration of the applicable statute of limitations
period. The right to indemnification, reimbursement or other remedy based upon such



49



---

representations, warranties, covenants and obligations shall not be affected by any investigation conducted with respect to, or knowledge acquired (or
capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date.

(b) The covenants and agreements of the parties contained in this Agreement shall survive the Closing indefinitely, except as expressly provided otherwise herein.

7.2 Indemnification and Other Rights.

(a) If the Closing occurs, each of the Stockholders shall, jointly and severally (except as stated in clause (i) below), indemnify and defend Eclipsys, and its Affiliates (including EPSI following the Closing),
each of their respective officers, directors, employees, stockholders, agents and representatives, and each of their respective successors and assigns (the Eclipsys Indemnified Parties) against and hold them harmless,
reimburse and make them whole from and against any loss, Liability, cost, damage or expense (including reasonable legal and expert fees and expenses incurred in investigation or defense of any of the same, or in asserting, preserving or enforcing
its rights hereunder) actually incurred or claims suffered by any such indemnified party (collectively Damages) to the extent arising from or in connection with (i) any breach or inaccuracy of any representation or
warranty of the Stockholders, or any of them, contained in this Agreement or any of the other Transaction Documents or facts and circumstances as they may exist contrary to the representations or warranties of the Stockholders, or any of them,
provided that (A) each Stockholder shall be solely liable for a breach by such Stockholder of the representations and warranties of such Stockholder in Article III, and such liability shall not be joint, and (B) for the
representations set forth in Sections 4.4, 4.10, 4.11, 4.14 and 4.18, with respect to Third Party Claims, notwithstanding disclosures set forth in the Stockholders Disclosure Schedule; (ii) any
breach of any covenant of the Stockholders, or any of them, contained in this Agreement; (iii) a Third Party Claim arising from or in connection with the operations of the Business before the Closing Date, including but not limited to
(A) errors and omissions in design, creation, implementation or maintenance of any of the Software Products, (B) any failure of any of the Software Products to conform to commitments made by or on behalf of EPSI to customers or third
parties before the Closing Date, and (C) any failure by EPSI prior to the Closing Date to perform all material obligations under the Material Contracts, and in each case notwithstanding disclosures set forth in the Stockholders Disclosure
Schedule; (iv) the business and operations of any business owned or operated in whole or part by any of the Stockholders or any of their Affiliates, including CPM, whether before or after the Closing Date (other than EPSI before the Closing
Date, as to which the other clauses to this Section 7.2(a) apply, to the extent expressly set forth herein); and (v) any claims by any current or former employees of EPSI or any of its predecessors arising from or in connection with
events or circumstances preceding the Closing, or arising from or in connection with the employment policies of EPSI in place at any time prior to the Closing, including those set forth in the EPSI Employee Handbook, or the reduction or termination
of any benefits provided thereunder, whether before or after the Closing Date, including life time health insurance coverage. The express written waiver by Eclipsys of any condition set forth in Section 9.2 based on the inaccuracy of any
representation or warranty, or on the nonperformance of or noncompliance with any covenant or obligation, will not preclude any right of Eclipsys or any other Eclipsys Indemnified Party to indemnification, payment of Damages, or other remedy based
on such



50



---

representation, warranty, covenant, or obligation to the extent arising from a Third Party Claim. For purposes of this Agreement, Damages shall include, but
not be limited to, the amount by which the value of EPSI and the Business is less than it would have been but for a breach or inaccuracy of the representations and warranties of the Stockholders, or the failure by the Stockholders to fulfill their
obligations hereunder.

(b) Each of the Stockholders hereby (i) irrevocably appoints the Stockholders
Representative as such Stockholders agent for service of any and all legal process, summons, notices and documents which may be served in any action or proceeding under or pursuant to this Agreement, (ii) waives any requirement of
personal notice or any claim that service on the Stockholders Representative is invalid or insufficient to constitute valid personal service on such Stockholder, and (iii) ratifies and confirms, and agrees to be bound by, all actions
taken by the Stockholders Representative on its behalf pursuant to the foregoing authorization.

(c) Eclipsys shall
indemnify the Stockholders and their Affiliates and each of their respective officers, directors, employees, stockholders, agents and representatives against and hold them harmless from any Damages to the extent arising from (i) any breach of
any representation or warranty of Eclipsys contained in this Agreement or any of the other Transaction Documents or facts and circumstances as they may exist contrary to representations or warranties of Eclipsys; and (ii) any breach of any
covenant of Eclipsys contained in this Agreement. The express written waiver by the Stockholders of any condition set forth in Section 9.3 based on the inaccuracy of any representation or warranty, or on the nonperformance of or
noncompliance with any covenant or obligation, will not preclude any right of the Stockholders to indemnification, payment of Damages, or other remedy based on such representation, warranty, covenant, or obligation to the extent arising from a Third
Party Claim.

(d) Any payments made pursuant to this Article VII shall be treated for all purposes as an adjustment
to the Purchase Price.

(e) The amount of any Damages subject to indemnification hereunder shall be reduced by any insurance
proceeds actually received by the indemnified party from an unrelated third party on account of such Damages, net of any expenses incurred in recovering such monies from the insurance carrier and any increase in premiums as a result of such claim.
The indemnified parties shall exercise commercially reasonable efforts to recover under any applicable insurance policies. If the indemnifying party pays any amount in respect of Damages subject to indemnification under this Article VII and,
subsequent to such payment the indemnified party actually recovers any such Damages under any such insurance policies, the indemnified party shall remit to the indemnifying party an amount equal to the amount of such insurance recovery on account of
such Damages (net of any expenses incurred in recovering such monies from the insurance carrier and any increase in premiums as a result of such claim), not to exceed the Damages previously paid by the indemnifying party with respect to such claim.
Nothing contained herein shall require an indemnified party to delay pursuit of rights hereunder, or permit an indemnifying party to delay prompt payment of amounts owed hereunder, in anticipation of receipt of any such insurance recovery.

(f) The amount of any Damages subject to indemnification hereunder shall be reduced by the amount of any net Tax benefit on
account of such Damages after the Closing



51



---

Date that is actually realized by the indemnified party in the Tax year in which the Damages to be indemnified hereunder are paid (exclusive of any Tax carry
forwards applicable to the indemnified party). If the indemnifying party pays any amount in respect of Damages subject to indemnification under this Article VII and, subsequent to such payment the indemnified party actually realizes a net Tax
benefit on account of such Damages in the Tax year in which the Damages to be indemnified hereunder are paid (exclusive of any Tax carry forwards applicable to the indemnified party), the indemnified party shall remit to the indemnifying party an
amount equal to the amount of such net Tax benefit actually realized by the indemnified party on account of such Damages, less any Tax benefits realized by the indemnified party as a result of paying such Damages, in an amount not to exceed the
Damages previously paid by the indemnifying party with respect to such claim. The parties shall use commercially reasonable efforts to realize all such Tax benefits. Nothing contained herein shall require an indemnified party to delay pursuit of
rights hereunder, or permit an indemnifying party to delay prompt payment of amounts owed hereunder, in anticipation of any such net Tax benefit.

(g) The Stockholders shall not be liable to Eclipsys for any Damages to the extent arising from (i) Exempt Errors, (ii) the failure of Eclipsys to correct Exempt Errors consistent with the practices of EPSI
prior to the Closing, or (iii) the failure of Eclipsys to communicate with each customer using the Software Products on the Closing Date in a commercially reasonable and responsive manner. The limitation set forth in the preceding
clause (i) shall not apply to Exempt Errors that result in out-of-pocket payments by Eclipsys or its Affiliates to any third party, including payments to consultants or Damages arising out of a breach of contract, representation or warranty or
fraud claim by any customer. Anything herein to the contrary notwithstanding, the Stockholders shall have no liability for Damages with respect to claims by any EPSI customer related to the performance, features or functionality of the Software
Products or support therefor unless (A) the sale to such customer was made by a person who was an employee of EPSI prior to the Closing Date, (B) the contract executed by such customer contains no more favorable warranty and
indemnification provisions than those used by EPSI prior to the Closing Date and (C) the Stockholders shall have been afforded a reasonable opportunity to cure any breach claimed or complaint made by such customer consistent with the custom and
practice of EPSI in effect prior to the Closing Date, provided nothing herein shall limit Eclipsys right to promptly respond to any customer issues, and if it does so, such response by Eclipsys shall not waive the right of Eclipsys to recover
hereunder, subject to the terms hereof. Nothing in the preceding sentence of this Section 7.2(g) shall limit Eclipsys right to recover from the Stockholders for any Damages arising from claims by Plante & Moran, or any of
its customers, provided that the Stockholders shall be provided a reasonable opportunity to cure any claimed breach as set forth in clause (C) above.

(h) The Stockholders shall not have any liability (for indemnification or otherwise) with respect to any matters under this Agreement to the extent resulting from acts or omissions of Eclipsys after the Closing Date,
including without limitation, changes by Eclipsys after the Closing Date in customer agreements, the form of customer demonstrations, customer warranties or specifications, marketing materials, Software design or operation and customer support.

Section 4.14), 4.15(a), 4.16, 4.23, 5.3 and 5.4, unless on or before the last day of the Survival Period, the party seeking recovery for Damages provides notice in writing pursuant to
Section 7.6 or Section 7.7 of a claim for Damages specifying the factual basis of that claim in reasonable detail to the extent then known by such party. In such event, the party giving such notice shall continue to have the
right to recover hereunder, and to all other rights and remedies under this Agreement, with respect to the matter or matters to which such claim relates until such claim has been finally resolved and payment made, if any.

(ii) Subject to Section 7.4, a claim with respect to Sections 3.1, 3.3, 4.3, 4.9, 4.10,
4.11(b), 4.14 (but excluding subsections (i), (o), (p) and (q) of said Section 4.14), 4.15(a), 4.16, 4.23, 5.3 or 5.4 must be made at any time prior to 30 days after the
expiration of the applicable statute of limitations period, unless on or before such date, the party seeking recovery for Damages provides the notice in writing pursuant to Sections 7.6 or 7.7 of a claim for Damages specifying the
factual basis of that claim in reasonable detail to the extent then known by such party. In such event, the party seeking recovery for Damages shall continue to have the right to recover hereunder, and to all other rights and remedies under this
Agreement, with respect to the matter or matters to which such claim relates until such claim has been finally resolved and payment made, if any.

(b) The Stockholders will not have any liability (for indemnification or otherwise) with respect to any matters under this Agreement described in Section 7.2(a)(iii), unless on or before the last day of
the Survival Period, Eclipsys provides notice in writing pursuant to Section 7.6 of a claim for Damages specifying the factual basis of that claim in reasonable detail to the extent then known by Eclipsys. Notwithstanding the foregoing,
with respect to any EPSI customer contracts executed after the Closing Date and before July 1, 2008 (including contracts of Plante & Moran customers), the survival period with respect to any matters under this Agreement described in

53



---

thresholds described in this Section 7.4(a) shall be inapplicable) unless with respect to (i) any claim (or series of claims based on the
same or similar or related facts, events, conditions or circumstances), the Damages exceed $25,000, or (ii) the total Damages for matters hereunder, the Damages exceed $150,000, but once such amounts have been met, then the Stockholders shall
be liable for all amounts of such Damages, including such $25,000 or $150,000, as applicable.

(b) Eclipsys will have no
liability (for indemnification or otherwise) with respect to any matters under this Agreement (except for Fraud by Eclipsys or the representations made in Section 5.1, 5.2, 5.3 or 5.4, as to which the thresholds
described in this Section 7.4(b) shall be inapplicable) unless with respect to (i) any individual claim or series of claims based on the same or similar or related facts, events, conditions or circumstances), the Damages exceed
$25,000, or (ii) the total Damages for matters hereunder, the Damages exceed $150,000, and then only for the amount by which such Damages exceed $25,000 or $150,000, as applicable.

(c) For purposes of this Article VII, the representations and warranties contained herein shall not be deemed qualified by any
references herein to materiality generally or to whether any such breach results or may result in a Material Adverse Effect or if a matter be or may not be reasonably likely to occur.

(d) The Stockholders liability (for indemnification or otherwise) with respect to any matters under this Agreement described in
Section 7.2(a) (other than claims of or causes of actions arising from Stockholder Fraud or under Section 7.2(a)(ii) or Section 7.2(a)(iv)) shall not exceed the Purchase Price; provided that the Stockholders
liability (for indemnification or otherwise) with respect to any matters under this Agreement described in Section 7.2(a)(i), other than breaches or inaccuracies of the representations and warranties in Section 3.1,
3.3, 4.3, 4.9, 4.10, 4.11(b), 4.14, 4.15(a), 4.16, 4.18 or 4.23, shall not exceed $26,500,000. The Stockholders liability arising from claims or causes of actions arising
from Stockholder Fraud or under Section 7.2(a)(ii) or Section 7.2(a)(iv) shall not be subject to any cap or limitation on amount.

(e) The liability of Eclipsys (for indemnification or otherwise) with respect to any breach or inaccuracy of its representations and warranties in this Agreement, shall not exceed, in the aggregate the portion of the
Purchase Price remaining unpaid, provided this limitation on liability shall not be applicable to any Damages incurred by the Stockholders with respect to any Third Party Claim, to the extent such Damages arise from any breach or inaccuracy by
Eclipsys of its representations and warranties in this Agreement.

7.5 Set-Off. In addition to any rights of set-off, off-set or
other rights that Eclipsys may have at common law, by statute or otherwise, Eclipsys shall have the right to set-off against (i) any amounts held by the Escrow Agent pursuant to the Holdback Escrow Agreement, (ii) the Pledged Stock, and
(iii) any amount that Eclipsys would otherwise be required to pay to any Stockholder, any amounts owing by any Stockholder to Eclipsys pursuant to this Article VII or Article VIII; provided however, that
(A) notwithstanding the exercise by Eclipsys of the right to set-off described in this Section 7.5, Eclipsys and the Stockholders shall remain obligated to first comply with their respective obligations described in
Section 7.6 and Section 7.7 and (B) with respect to a breach or inaccuracy of the representations and warranties of a Stockholder under Article III, Eclipsys shall only have the right to set-off against any
amounts held by the Escrow



54



---

Agent pursuant to the Holdback Escrow Agreement, such Stockholders Pledged Stock or any amounts that Eclipsys would be required to pay such
Stockholder. Neither the exercise of nor failure to exercise any such right of set off will constitute an election of remedies or limit Eclipsys in any manner in the enforcement of other remedies available to it hereunder and the exercise by
Eclipsys of the right of set off against the amounts held under the Holdback Escrow Agreement, the Pledged Stock or other amounts Eclipsys would otherwise be required to pay to any Stockholder shall not be the sole or exclusive remedy of Eclipsys
for recovery of any amounts owed by the Stockholders to Eclipsys under this Article VII or Article VIII.

7.6
Procedures Relating to Indemnification Involving Third Party Claims.

(a) In order for a party to be entitled to any
indemnification provided for under this Agreement in respect of, arising out of or involving a claim or demand made by any Person not a party to this Agreement against such party (a Third Party Claim), such indemnified
party must promptly notify the indemnifying party in writing, and in reasonable detail, of the Third Party Claim after receipt by such indemnified party of written notice of the Third Party Claim; provided however, that failure to give such
notification shall not affect the indemnification provided hereunder except to the extent that the indemnifying party shall have been actually prejudiced as a result of such failure. Thereafter, the indemnified party shall promptly deliver to the
indemnifying party after the indemnified partys receipt thereof, copies of all notices and documents (including court papers) received by the indemnified party relating to the Third Party Claim. In the event the provisions of
Sections 8.3 or 8.4 are inconsistent with any provision of this Article VII, the provisions of Sections 8.3 or 8.4 shall control with respect to the contest of Tax matters. In the event that more
than one Stockholder is an indemnifying party hereunder, the indemnified party may provide the notices and other communications required pursuant to this Section 7.6 solely to the Stockholders Representative.

(b) If a Third Party Claim is made against an indemnified party, the indemnifying party shall be entitled to participate in the defense
thereof and, if it promptly so chooses and acknowledges its obligation to indemnify the indemnified party therefor, to assume the defense thereof with counsel selected by the indemnifying party; provided that such counsel is not reasonably objected
to by the indemnified party. Should the indemnifying party assume the defense of a Third Party Claim, the indemnifying party shall not be liable to the indemnified party for legal expenses subsequently incurred by the indemnified party in connection
with the defense thereof. If the indemnifying party assumes such defense, the indemnified party shall have the right to participate in the defense thereof and to employ counsel (not reasonably objected to by the indemnifying party), at its own
expense, separate from the counsel employed by the indemnifying party, it being understood that the indemnifying party shall control such defense. However, notwithstanding the foregoing, if Eclipsys or any of its Affiliates is an indemnified party
in connection with a Third Party Claim involving any then current employee, any then current client or supplier or the owner of any Intellectual Property then used in the Business, Eclipsys may control the defense, at the cost of the indemnifying
party, subject to reasonable input from the indemnifying party, with reasonableness determined by reference, among other things, to any conflicting interests between the indemnified party and indemnifying party.



55



---

(c) The indemnifying party shall be liable for the reasonable fees and expenses of
counsel employed by the indemnified party in connection with a Third Party Claim for any period during which the indemnifying party has failed to assume or is not entitled to assume the defense thereof, provided however, the indemnifying
party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one
separate firm of attorneys (in addition to one local counsel, where applicable). In connection with any Third Party Claim, the indemnified party and the indemnifying party shall cooperate with each other in the defense or prosecution thereof. Such
cooperation shall include the retention and (upon the indemnified or indemnifying partys request) the provision to such party of records and information which are reasonably relevant to such Third Party Claim, and making employees available on
a mutually convenient basis to provide additional information and explanation of any material provided hereunder, including deposition or trial testimony.

(d) If the indemnifying party shall have assumed the defense of a Third Party Claim, the indemnified party shall not have the right to settle or compromise such claim, and shall agree to any settlement, compromise or
discharge of a Third Party Claim which the indemnifying party may recommend and which by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Third Party Claim, which releases the indemnified
party completely in connection with such Third Party Claim and which would not otherwise adversely affect the indemnified party. If the indemnifying party shall not have assumed the defense of a Third Party Claim, the indemnified party may settle,
compromise or discharge, such Third Party Claim in good faith without the indemnifying partys prior consent.

(e)
Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Third Party Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Third
Party Claim) if:

(i) the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than
money damages against the indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages, or

(ii) the indemnified party reasonably determines, after conferring with its outside counsel, that joint representation would be expected
to give rise to a conflict of interest.

If such equitable relief or other relief portion of the Third Party Claim can be so
separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages. All claims under Section 7.2 other than Third Party Claims shall be governed by
Section 7.7.

7.7 Other Claims. A claim by any party for reimbursement, make whole or other recovery for Damages arising
from any event, circumstance or condition not involving a Third Party Claim may be asserted by written notice to the party or parties from whom such recovery is



56



---

sought (or to the Stockholders Representative, if such recovery is sought from more than one of the Stockholders) and shall be paid promptly after
receipt of such notice. Notwithstanding the foregoing, no party shall be liable to any other for any punitive damages pursuant to this Section 7.7.

7.8 Recovery in the Case of Strict Liability or Negligence. THE PROVISIONS IN THIS ARTICLE VII SHALL BE ENFORCEABLE REGARDLESS OF WHETHER THE DAMAGES ARE BASED ON PAST, PRESENT OR FUTURE ACTS, CLAIMS OR
LEGAL REQUIREMENTS (INCLUDING ANY ENVIRONMENTAL LAW OR PRODUCTS LIABILITY LAW), AND REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION OR OTHER RECOVERY IS SOUGHT) ALLEGES OR PROVES THE CONCURRENT, CONTRIBUTORY OR
COMPARATIVE NEGLIGENCE OF THE PERSON SEEKING SUCH INDEMNIFICATION OR OTHER RECOVERY, OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED ON THE PERSON SEEKING SUCH INDEMNIFICATION OR OTHER RECOVERY.

7.9 Sole and Exclusive Remedy.

(a) Should the Closing occur (i) the sole and exclusive remedies of Eclipsys for any breach or inaccuracy of the representations and warranties of the Stockholders under this Agreement and any other Transaction
Documents, whether such claims be in contract, tort or otherwise, shall be the remedies provided in this Article VII and Article VIII, and Eclipsys hereby waives, from and after the Closing, any and all other remedies which
may be available at law or equity for any breach or inaccuracy or alleged breach or inaccuracy of the representations and warranties of the Stockholders hereunder, and (ii) the Stockholders sole and exclusive remedies for any breach or
inaccuracy of the representations and warranties of Eclipsys under this Agreement and any other Transaction Documents, whether such claims be in contract, tort or otherwise, shall be the remedies provided in this Article VII and
Article VIII, and each of the Stockholders hereby waives, from and after the Closing, any and all other remedies which may be available at law or equity for any breach or inaccuracy or alleged breach or inaccuracy of the representations
and warranties of Eclipsys hereunder.

(b) Nothing in this Article VII will (i) limit the right of any party to
seek injunctive or other equitable relief for any breach or alleged or threatened breach of any covenant in this Agreement or any other Transaction Document, provided that the exercise of any equitable relief shall be subject to
Section 11.11, or (ii) limit the rights of the Stockholders to seek any remedies with respect to Fraud by Eclipsys, or Eclipsys to seek any remedies with respect to Stockholder Fraud in connection herewith or transactions
contemplated hereby (including limiting the time such claims can be made, or making such claims subject to any deductibles set forth herein).

(c) For the avoidance of doubt, the concept of indemnity as used in this Article VII is intended to include claims between or among the parties to this Agreement and not involving any third
party, as well as Third Party Claims, and the limitation set forth in this Section 7.9 of remedies for breach or inaccuracies of representations and warranties under this Agreement is not intended to preclude claims between or among the
parties, including but not limited to claims for breach of contract or Fraud, which claims are, however, intended to be governed by this Article VII.

ARTICLE VIII

TAX MATTERS

8.1 Indemnification Obligations With Respect to Taxes.

(a) The Stockholders shall, jointly and severally, be responsible for, and shall indemnify, defend and hold harmless Eclipsys and EPSI
from and against:

(i) all Taxes of EPSI due with respect to periods ending on or prior to the Closing Date
(notwithstanding any disclosure set forth on the Stockholders Disclosure Schedule), except to the extent specific reserves for such Taxes were reflected on the balance sheet of EPSI as of the Closing Date;

(ii) all Taxes of EPSI that are due with respect to a Tax period that includes but does not end on the Closing Date (a
Straddle Period) to the extent attributable to the portion of the Straddle Period ending at the close of business on the Closing Date;

(iii) all losses resulting from any inaccuracy in or breach of the representations and warranties with respect to Tax matters that are
contained in Section 4.9 or in this Article VIII and any covenants contained in this Agreement with respect to Tax matters (without giving effect to any supplement to the Stockholders Disclosure Schedule delivered after
the date hereof), or contained in any certificate or other Transaction Document delivered pursuant hereto; and

(iv) all
losses imposed on or sustained by Eclipsys or its Affiliates (including EPSI after the Closing Date), directly or indirectly, by reason of or in connection with the foregoing amounts.

(b) Eclipsys shall be responsible for, and shall indemnify, defend and hold harmless the Stockholders from and against:

(i) all Taxes of EPSI that are due with respect to periods commencing after the Closing Date; and

(ii) all Taxes of EPSI that are due with respect to Straddle Periods to the extent attributable to the portion of the Straddle Period
commencing after the Closing Date.

(c) For purposes of this Article VIII, whenever it is necessary to determine the
liability for Taxes of EPSI for a Straddle Period, the determination of the Taxes for the portion of the Straddle Period ending on and including, and the portion of the Straddle Period beginning after, the Closing Date shall be determined by
assuming that the Straddle Period consisted of two taxable years or periods, one which ended at the close of the Closing Date and the other which began at the beginning of the day following the Closing Date, and items of income, gain,



58



---

deduction, loss or credit, and state and local apportionment factors of EPSI for the Straddle Period shall be allocated between such two taxable years or
periods on a closing of the books basis by assuming that the books of EPSI were closed at the close of business on the Closing Date; provided however, (i) exemptions, allowances or deductions that are calculated on an annual
basis, such as the deduction for depreciation; and (ii) periodic taxes, such as real and personal property taxes, shall be apportioned ratably between such periods on a daily basis.

(d) Notwithstanding anything to the contrary in this Agreement (including provisions set forth in Article VII of this Agreement),
the obligations of the Stockholders and Eclipsys under this Article VIII shall be unconditional and absolute, shall not be limited, shall not be subject to a deductible, threshold, cap, or similar concept, and shall remain in effect
until 30 days after the expiration of all applicable statutes of limitation as to time.

8.2 Tax Returns and Payment
Responsibility.

(a) The Stockholders will be responsible for and will cause to be prepared and duly filed all Tax
Returns of EPSI for all periods ending on or prior to the Closing Date that are filed after the Closing Date. The Stockholders shall permit Eclipsys to review and comment on each such Tax Return described in the preceding sentence prior to filing,
and shall pay any Taxes due in respect of the Tax Returns described in the preceding sentence. Eclipsys shall file or cause to be filed when due all Tax Returns with respect to EPSI due after the Closing Date, other than those that are the
responsibility of the Stockholders pursuant to this section. Without affecting the indemnification obligations of the Stockholders under this Agreement, in the event that the Stockholders fail to prepare and file or cause to be prepared and filed
any Tax Return that they are required to file pursuant to this section, Eclipsys shall have the right, but not the obligation, to prepare and file all such Tax Returns at the expense of the Stockholders. The Stockholders shall pay by wire transfer
to Eclipsys the Taxes for which they are liable pursuant to this Article VIII (including Taxes set forth in Section 8.1(a)(i) and (ii)), but which are payable with Tax Returns to be filed by Eclipsys pursuant to this
section at least three Business days prior to the due date for the payment of such Taxes.

(b) Except as provided in
Section 6.15(c)(iv), all sales, use, transfer and other similar Taxes, including any stock or asset transfer stamp Taxes shall be borne jointly and severally by the Stockholders.

8.3 Contest Provisions.

(a) In the event (i) any Stockholder or their Affiliates or (ii) Eclipsys or its Affiliates receive notice of any pending or threatened Tax audits or assessments or other disputes concerning Taxes with respect to which the other
party may incur liability under this Article VIII, the party in receipt of such notice shall promptly notify the other party of such matter in writing, provided that failure to comply with this provision shall not affect a partys
right to indemnification hereunder unless such failure materially adversely affects the partys ability to challenge such Tax audits or assessments.

(b) The Stockholders shall have the sole right to represent the interests of EPSI in any Tax audit or administrative or court proceeding relating to any Tax for any taxable



59



---

period ending on or before the Closing Date, and to employ counsel of their choice at their expense. Notwithstanding the foregoing, the Stockholders shall
not be entitled to settle, either administratively or after the commencement of litigation, any claim for Taxes with respect to any Tax Return of EPSI that is not prepared on a consolidated, combined or unitary basis which would adversely affect the
liability for Taxes of Eclipsys or EPSI for any period after the Closing Date to any extent (including, but not limited to, the imposition of income Tax deficiencies, the reduction of asset basis or cost adjustments, the lengthening of any
amortization or depreciation periods, the denial of amortization or depreciation deductions, or the reduction of the loss or credit carry forwards) without the prior written consent of Eclipsys, which consent shall not be unreasonably withheld, and
such consent shall not be necessary to the extent that the Stockholders have indemnified Eclipsys against the effect of any such settlement.

(c) Eclipsys shall have the sole right to represent the interests of EPSI in any Tax audit or administrative or court proceeding relating to Taxes with respect to taxable periods including (but not ending on) or
beginning after the Closing Date and to employ counsel of its choice at its expense, provided that Eclipsys shall not be entitled to settle, either administratively or after the commencement of litigation, any claim regarding Taxes that would
adversely affect the liability of the Stockholders for any Taxes for any period ending on or before the Closing Date or for any Straddle Period, without the prior consent of the Stockholders Representative, which consent shall not be
unreasonably withheld and shall not be required to the extent that Eclipsys has indemnified the Stockholders against the effects of such settlement. Where consent to a settlement is withheld by the Stockholders Representative pursuant to this
section, the Stockholders may continue or initiate any further proceedings at their own expense, provided that the liability of Eclipsys, after giving effect to this Agreement, shall not exceed the liability that would have resulted from the
settlement or amended return.

8.4 Assistance and Cooperation. After the Closing Date, the Stockholders, on the one hand, and
Eclipsys, on the other hand, shall (and shall cause their respective Affiliates to): (a) assist the other party in preparing (including executing) and filing any Tax Returns or reports which such other party is responsible for preparing and
filing in accordance with this Article VIII; (b) cooperate fully in preparing for any audits of, or disputes with taxing authorities regarding, any Tax Returns of EPSI; (c) make available to the other and to any Taxing
authority as reasonably requested all information, records, and documents relating to Taxes of EPSI; (d) provide timely notice to the other in writing of any pending or threatened Tax audits or assessments of EPSI for Taxable periods for which
the other may have a liability under this Article VIII; and (e) furnish the other with copies of all correspondence received from any Taxing authority in connection with any Tax audit or information request with respect to any such
taxable period.

8.5 Retention of Records. After the Closing Date, the Stockholders, Eclipsys and EPSI will preserve all
information, records or documents relating to liabilities for Taxes of EPSI until six months after the expiration of any applicable statute of limitations (including extensions thereof) with respect to the assessment of such Taxes, provided that
neither party shall dispose of any of the foregoing items without first offering such items to the other party.

8.6 Other
Provisions. The provisions of this Article VIII (and not Section 7.2) shall govern all indemnity claims with respect to Tax matters of EPSI and the Stock Purchase. All indemnity payments under this Agreement (whether
arising under this Article VIII, or otherwise) shall be treated as an adjustment to the Purchase Price for Tax purposes.

of the State of Delaware, regardless of the laws or rules that might otherwise govern under applicable principles of conflicts of laws thereof. In the event of the bringing of any action or suit by a party hereto against another party hereunder
arising out of or relating to this Agreement, which claim or suit is not subject to arbitration, as determined pursuant to Section 11.14, then in that event, the sole forum for resolving such disputes shall be the state and federal
courts located in Delaware, and each of the parties hereby irrevocably submits to such exclusive jurisdiction. This section shall survive any termination of this Agreement and the Closing.

11.5 Construction.

(a) The headings herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement. Unless the context clearly requires otherwise or is not
exclusive, and includes means includes, but is not limited to.

(b) Each of the parties acknowledges
that it has been represented by counsel of its choice throughout all negotiations that have preceded the execution of this Agreement and that each party and its counsel cooperated in the drafting and preparation of this Agreement and the other
Transaction Documents, and any and all drafts relating thereto exchanged between the parties shall not be construed against any party by reason of its preparation. Accordingly, any Legal Requirement that would require interpretation of any
ambiguities in this Agreement against any party that drafted it shall be of no application and is hereby expressly waived.

(c) For purposes of this Agreement, commercially reasonable efforts will not be deemed to require a Person to undertake extraordinary or unreasonable measures, including the payment of amounts in excess of normal and usual
filing fees and processing fees.

11.6 Counterparts. This Agreement may be executed in counterparts, including facsimile
counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile transmission or PDF by electronic

11.8 Prior Review and Counsel. Eclipsys on the one hand, and the Stockholders jointly, on the
other hand each represents and warrants that: (a) it was provided a fair and reasonable time in which to evaluate this Agreement and the other Transaction Documents and to negotiate their respective terms and conditions; (b) it has
regularly consulted with and received advice and counsel from one or more attorneys of its own choice regarding the Stock Purchase, this Agreement, the other Transaction Documents and the negotiation of each and every one of them, which attorney(s)
is/are not and was/were not any of the other partys attorneys; (c) it has not received any legal or other substantive advice or any attorney work product from any of the other partys attorneys (including in-house attorneys), and it
has not relied upon any comment, observation, remark, communication or information (whether oral or written) made or delivered by any of the other partys attorneys (including in-house attorneys); and (d) it has read and fully understands
this Agreement and each of the other Transaction Documents. Each partys attorneys (including in-house attorneys) shall be entitled to rely on the other partys representations and warranties made in this Section 11.8 as
intended beneficiaries of such representations and warranties.

11.9 Waiver. No waiver of any breach of the provisions of this
Agreement will be deemed to have been made by any party, unless such waiver is expressed in writing and signed by the party against which it is to be enforced (or the Stockholders Representative, with respect to matters relating to all
Stockholders). The waiver by any party of any right under this Agreement or to a remedy for the breach of any of the provisions herein shall not operate nor be construed by the breaching party as a waiver of the non-breaching partys remedies
with respect to any other or continuing or subsequent breach.

11.10 Amendments.No amendment or modification in respect of
this Agreement shall be effective unless it shall be in writing and signed by the parties hereto (or the Stockholders Representative, with respect to matters relating to all Stockholders).

by the Stockholders in accordance with the terms hereof and that Eclipsys shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by the Stockholders and to enforce specifically the terms and provisions of this

11.14 Arbitration.

(a) Any dispute, claim or controversy arising out of or relating to this Agreement or any other Transaction Document (other than the
Employment Agreement and Restricted Stock Agreement) or the breach, termination, enforcement, interpretation or validity thereof, including the determination of the scope or applicability of this Agreement to arbitrate, shall be determined by
arbitration in St. Louis, Missouri,before a sole arbitrator; provided however, if the claim and any counterclaim, in the aggregate, exceed $750,000, exclusive of interest and attorneys fees, the dispute shall be heard and determined by
three arbitrators as provided herein. If such dispute, claim or controversy arises at the same time and relates to the same or similar facts, claims or events, such disputes, claims or controversies shall, to the extent practicable, be combined in
one arbitration proceeding, and in such event, the provisions of this Agreement governing dispute resolution shall supersede any provisions relating to such matters in the other Transaction Documents. If any dispute, claim or controversy arising out
of or relating to this Agreement or any other Transaction Document (other than the Employment Agreement and Restricted Stock Agreement) arises at the same time and relates to the same or similar facts, claims or events as a dispute, claim or
controversy relating to or arising out of the Employment Agreement of any Stockholder, the employment of any Stockholder by Eclipsys or any of its Affiliates including EPSI, or the Restricted Stock Agreement, such disputes, claims or controversies
shall, to the extent practicable, be combined in one arbitration proceeding, and in such event, the provisions of this Agreement governing dispute resolution shall supersede any provisions relating to such matters in the Employment Agreement between
any such Stockholder and Eclipsys or any Affiliate of Eclipsys or the Restricted Stock Agreement. For the avoidance of doubt, no claim under the Employment Agreement or Restricted Stock Agreements shall be governed by this provision, unless they
arise at the same time and relate to the same or similar facts, claims or events as a dispute, claim or controversy relating to or arising out of this Agreement or any other Transaction Document (other than the Employment Agreement and Restricted
Stock Agreement).

(b) Notwithstanding the foregoing, if any dispute, claim or controversy arising out of or relating to
this Agreement or any other Transaction Document (other than a dispute solely relating to any Employment Agreement or Restricted Stock Agreement), the parties shall first try to resolve their dispute through informal and good faith negotiation
between the Stockholders Representative and an authorized officer of Eclipsys, with authority to settle such dispute claim or controversy, before resorting to arbitration. Such persons shall meet for the purpose of endeavoring to resolve such
dispute, claim or controversy within ten Business Days after a written request from either the Stockholders Representative or Eclipsys to the other. Such representatives shall discuss the problem and negotiate in good faith in an effort to
resolve the dispute promptly and without the necessity of any formal arbitration proceeding relating thereto. The location, format and duration (not to exceed three Business Days, unless mutually agreed by such representatives) of these
negotiations shall be left to the discretion of the representatives involved. If such negotiations do not lead to resolution of the underlying dispute, claim or controversy to the satisfaction of any party, then any party may provide notice of
the election to pursue resolution by arbitration as set forth herein.

(c) The arbitration shall be conducted by JAMS pursuant to the Comprehensive Arbitration
Rules of JAMS. All arbitrators shall be retired or former district court or appellate court judges of any United States District Court or United States Court of Appeals, other than Courts in the States of Missouri, Illinois, Georgia or Florida, or
such other person with such other qualifications as Eclipsys and the Stockholders Representative may agree, and shall be selected within seven Business Days after receipt of notice from one party to another that it intends to seek arbitration
hereunder. The Federal Rules of Evidence shall govern the admissibility of evidence during the arbitration. The arbitrator(s) will have no authority to award punitive or other damages not measured by the prevailing partys actual damages,
except as may be required by statute. The determination of the arbitrator(s) shall be final and binding on the parties and a judgment on such award or determination may be entered in any court of competent jurisdiction and such judgment shall be
final and non-appealable. The decision and award of the arbitrator(s) shall be accompanied by a reasoned opinion.

(d) All
parties covenant not to appeal or otherwise litigate or file any court action that would seek to delay, amend, vacate or otherwise alter the determination of the arbitrator(s).

11.15 Costs and Fees. The prevailing party in any arbitration or court proceeding under this Agreement will be entitled to recover its fees and
costs incurred in the arbitration or proceeding (including attorneys and arbitration fees and costs) from the non-prevailing party, provided that the arbitrator or judge has the discretion to determine that there is no prevailing party or to
eliminate or reduce the prevailing partys recovery of its costs and fees to the extent that the arbitrator or judge determines that full recovery thereof would be unreasonable or disproportionate to the harm suffered by the prevailing party.
In absence of a determination of a prevailing party, the parties shall split equally all costs and fees. Costs and fees mean all reasonable pre-award expenses of the arbitration or other proceeding, including the
arbitrators fees, administrative fees, travel expenses, out-of-pocket expenses such as copying and telephone, court costs, witness fees, expert costs and fees, and attorneys fees, costs and expenses and other costs incurred in enforcing,
perfecting and executing such judgment or order. For the purposes of this section, attorneys fees, costs and expenses shall include all such fees, costs and expenses incurred in (i) appeals, (ii) post-judgment motions,
(iii) contempt proceedings, (iv) garnishment, levy, and debtor and third party examinations, (v) discovery, and (vi) bankruptcy litigation.
