IDX SYSTEMS CORPORATION

                        1995 EMPLOYEE STOCK PURCHASE PLAN

                       As Amended Through October 16, 1995


         The purpose of this Plan is to provide eligible employees of IDX
Systems Corporation (the "Company") and certain of its subsidiaries with
opportunities to purchase shares of the Company's common stock, $.01 par value
(the "Common Stock"), commencing on the effective date of the Company's initial
public offering of shares of Common Stock. Five Hundred Thousand (500,000)
shares of Common Stock in the aggregate have been approved for this purpose.

         1. ADMINISTRATION.  The Plan will be  administered  by the Company's
Board of Directors (the "Board") or by a Committee  appointed by the Board (the
"Committee").  The Board or the  Committee has authority to make rules and
regulations for the  administration of the Plan and its interpretation and
decisions with regard thereto shall be final and conclusive.

         2. ELIGIBILITY. Participation in the Plan will neither be permitted nor
denied contrary to the requirements of Section 423 of the Internal Revenue Code
of 1986, as amended (the "Code"), and regulations promulgated thereunder. All
employees of the Company, including Directors who are employees, and all
employees of any subsidiary of the Company (as defined in Section 424(f) of the
Code) designated by the Board or the Committee from time to time (a "Designated
Subsidiary"), are eligible to participate in any one or more of the offerings of
Options (as defined in Section 9) to purchase Common Stock under the Plan
provided that:

                  (a)      they are regularly employed by the Company or a
         Designated Subsidiary for more than 20 hours a week and for more than
         one month in a calendar year; and

                  (b)      they have been employed by the Company or a
         Designated Subsidiary for at least one month prior to enrolling in the
         Plan; and

                  (c)      they are employees of the Company or a Designated
         Subsidiary on the first day of the applicable Plan Period (as defined
         below).

         No employee may be granted an option hereunder if such employee,
immediately after the option is granted, owns 5% or more of the total combined
voting power or value of the stock of the Company or any subsidiary. For
purposes of the preceding sentence, the attribution rules of Section 424(d) of
the Code shall apply in determining the stock ownership of an employee, and all
stock which the employee has a contractual right to purchase shall be treated as
stock owned by the employee.

         3. OFFERINGS. The Company will make one or more offerings ("Offerings")
to employees to purchase stock under this Plan. The initial Offering will begin

                                     Page 1
<PAGE>

on the date that the shares of Common Stock are priced in the Company's initial
public offering and will terminate on June 30, 1996; thereafter Offerings will
occur each January 1 and July 1, or the first business day thereafter,
commencing July 1, 1996 (the "Offering Commencement Dates"). After the period of
the initial Offering, each Offering Commencement Date will begin six (6) month
Offering periods during which payroll deductions will be made and held for the
purchase of Common Stock at the end of the Plan Period. The Board or the
Committee may, at its discretion, choose a different Offering period of twelve
(12) months or less. As used in this Plan, the term "Plan Period" means the
initial Offering period and subsequent Offering periods.

         4. PARTICIPATION. An employee eligible on the Offering Commencement
Date of any Offering may participate in such Offering by completing and
forwarding a payroll deduction authorization form to the employee's appropriate
payroll office at least ten (10) days prior to the applicable Offering
Commencement Date. The form will authorize a regular payroll deduction from the
Compensation received by the employee during the Plan Period. Unless an employee
files a new form or withdraws from the Plan, his deductions and purchases will
continue at the same rate for future Offerings under the Plan as long as the
Plan remains in effect. The term "Compensation" means the amount of money
reportable on the employee's Federal Income Tax Withholding Statement, excluding
overtime, shift premium, incentive or bonus awards, allowances and
reimbursements for expenses such as relocation allowances for travel expenses,
income or gains on the exercise of Company stock options or stock appreciation
rights, and similar items, whether or not shown on the employee's Federal Income
Tax Withholding Statement, but including, in the case of salespersons, sales
commissions to the extent determined by the Board or the Committee.

         5. DEDUCTIONS. The Company will maintain payroll deduction accounts for
all participating employees. With respect to any Offering made under this Plan,
an employee may authorize a payroll deduction in any dollar amount up to a
maximum of 10% of the Compensation he or she receives during the Plan Period or
such shorter period during which deductions from payroll are made. The minimum
payroll deduction is such percentage of compensation as may be established from
time to time by the Board or the Committee.

         No employee may be granted an Option (as defined in Section 9) which
permits his rights to purchase Common Stock under this Plan and any other stock
purchase plan of the Company and its subsidiaries, to accrue at a rate which
exceeds $25,000 of the fair market value of such Common Stock (determined at the
Offering Commencement Date of the Plan Period) for each calendar year in which
the Option is outstanding at any time.

         6. DEDUCTION CHANGES. An employee may decrease or discontinue his
payroll deduction once during any Plan Period, by filing a new payroll deduction
authorization form. However, an employee may not increase his payroll deduction
during a Plan Period. If an employee elects to discontinue his payroll
deductions during a Plan Period, but does not elect to withdraw his funds
pursuant to Section 8 hereof, funds deducted prior to his election to
discontinue will be applied to the purchase of Common Stock on the Exercise Date
(as defined below).

                                     Page 2
<PAGE>

         7. INTEREST.  Interest will not be paid on any employee accounts,
except to the extent that the Board or the Committee, in its sole discretion,
elects to credit employee accounts with interest at such perannum rate as it may
from time to time determine.

         8. WITHDRAWAL OF FUNDS. An employee may at any time prior to the close
of business on the last business day in a Plan Period and for any reason
permanently draw out the balance accumulated in the employee's account and
thereby withdraw from participation in an Offering. Partial withdrawals are not
permitted. The employee may not begin participation again during the remainder
of the Plan Period. The employee may participate in any subsequent Offering in
accordance with terms and conditions established by the Board or the Committee,
except that employees who are also directors or officers of the Company within
the meaning of Section 16 of the Securities Exchange Act of 1934 (the "Exchange
Act") and the rules promulgated there under may not participate again for a
period of at least six months as provided in Rule 16b-3(d)(2)(i) or any
successor provision.

         9. PURCHASE OF SHARES. On the Offering Commencement Date of each Plan
Period, the Company will grant to each eligible employee who is then a
participant in the Plan an option ("Option") to purchase on the last business
day of such Plan Period (the "Exercise Date"), at the Option Price hereinafter
provided for, such number of whole shares of Common Stock of the Company
reserved for the purposes of the Plan as does not exceed the number of shares
determined by dividing 12% of such employee's annualized Compensation for the
immediately prior six-month period by the price determined in accordance with
the formula set forth in the following paragraph but using the closing price on
the Offering Commencement Date of such Plan Period.

         The purchase price for each share purchased will be 85% of the closing
price of the Common Stock on (i) the first business day of such Plan Period or
(ii) the Exercise Date, whichever closing price shall be less. Such closing
price shall be (a) the closing price on any national securities exchange on
which the Common Stock is listed, (b) the closing price of the Common Stock on
the Nasdaq National Market or (c) the average of the closing bid and asked
prices in the over-the-counter-market, whichever is applicable, as published in
The Wall Street Journal. If no sales of Common Stock were made on such a day,
the price of the Common Stock for purposes of clauses (a) and (b) above shall be
the reported price for the next preceding day on which sales were made.

         Each employee who continues to be a participant in the Plan on the
Exercise Date shall be deemed to have exercised his Option at the Option Price
on such date and shall be deemed to have purchased from the Company the number
of full shares of Common Stock reserved for the purpose of the Plan that his
accumulated payroll deductions on such date will pay for pursuant to the formula
set forth above (but not in excess of the maximum number determined in the
manner set forth above).

         Any balance remaining in an employee's payroll deduction account at the
end of a Plan Period will be automatically refunded to the employee, except that
any balance which is less than the purchase price of one share of Common Stock
will be carried forward into the employee's payroll deduction account for the


                                     Page 3

<PAGE>

following Offering, unless the employee elects not to participate in the
following Offering under the Plan, in which case the balance in the employee's
account shall be refunded.

         10. ISSUANCE OF CERTIFICATES. Certificates representing shares of
Common Stock purchased under the Plan may be issued only in the name of the
employee, in the name of the employee and another person of legal age as joint
tenants with rights of survivorship, or (in the Company's sole discretion) in
the street name of a brokerage firm, bank or other nominee holder designated by
the employee.

         11. Rights on Retirement, Death or Termination of Employment. In the
event of a participating employee's termination of employment prior to the last
business day of a Plan Period, no payroll deduction shall be taken from any pay
due and owing to an employee and the balance in the employee's account shall be
paid to the employee or, in the event of the employee's death, (a) to a
beneficiary previously designated in a revocable notice signed by the employee
(with any spousal consent required under state law) or (b) in the absence of
such a designated beneficiary, to the executor or administrator of the
employee's estate or (c) if no such executor or administrator has been appointed
to the knowledge of the Company, to such other person(s) as the Company may, in
its discretion, designate. If, prior to the last business day of the Plan
Period, the Designated Subsidiary by which an employee is employed shall cease
to be a subsidiary of the Company, or if the employee is transferred to a
subsidiary of the Company that is not a Designated Subsidiary, the employee
shall be deemed to have terminated employment for the purposes of this Plan.

         12. OPTIONEES NOT STOCKHOLDERS. Neither the granting of an Option to an
employee nor the deductions from his pay shall constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him.

         13.  RIGHTS NOT TRANSFERABLE.  Rights under this Plan are not
transferable  by a  participating  employee  other  than by will or the  laws of
descent and  distribution,  and are exercisable  during the employee's  lifetime
only by the employee.

         14.  APPLICATION OF FUNDS.  All funds received or held by the Company
under this Plan may be combined with other  corporate  funds and may be used for
any corporate purpose.

         15. ADJUSTMENT IN CASE OF CHANGES AFFECTING COMMON STOCK. In the event
of a subdivision of outstanding shares of Common Stock, or the payment of a
dividend in Common Stock, the number of shares approved for this Plan, and the
share limitation set forth in Section 9, shall be increased proportionately, and
such other adjustment shall be made as may be deemed equitable by the Board or
the Committee. In the event of any other change affecting the Common Stock, such
adjustment shall be made as may be deemed equitable by the Board or the
Committee to give proper effect to such event.

                                     Page 4
<PAGE>

         16. MERGER. If the Company shall at any time merge or consolidate with
another corporation and the holders of the capital stock of the Company
immediately prior to such merger or consolidation continue to hold at least 80%
by voting power of the capital stock of the surviving corporation ("Continuity
of Control"), the holder of each Option then outstanding will thereafter be
entitled to receive at the next Exercise Date upon the exercise of such Option
for each share as to which such Option shall be exercised the securities or
property which a holder of one share of the Common Stock was entitled to upon
and at the time of such merger, and the Board shall take such steps in
connection with such merger as the Board shall deem necessary to assure that the
provisions of Paragraph 15 shall thereafter be applicable, as nearly as
reasonably may be, in relation to the said securities or property as to which
such holder of such Option might thereafter be entitled to receive thereunder.

         In the event of a merger or consolidation of the Company with or into
another corporation which does not involve Continuity of Control, or of a sale
of all or substantially all of the assets of the Company while unexercised
Options remain outstanding under the Plan, (a) subject to the provisions of
clauses (b) and (c), after the effective date of such transaction, each holder
of an outstanding Option shall be entitled, upon exercise of such Option, to
receive in lieu of shares of Common Stock, shares of such stock or other
securities as the holders of shares of Common Stock received pursuant to the
terms of such transaction; or (b) all outstanding Options may be cancelled by
the Board or the Committee as of a date prior to the effective date of any such
transaction and all payroll deductions shall be paid out to the participating
employees; or (c) all outstanding Options may be cancelled by the Board or the
Committee as of the effective date of any such transaction, provided that notice
of such cancellation shall be given to each holder of an Option, and each holder
of an Option shall have the right to exercise such Option in full based on
payroll deductions then credited to his account as of a date determined by the
Board or the Committee, which date shall not be less than ten (10) days
preceding the effective date of such transaction. Notwithstanding anything to
the contrary in the foregoing, the merger of the Company into a corporation of
another state for the purpose of reincorporating the Company in such other state
shall not be deemed to be a Change in Control under the Plan, and the Plan shall
continue as a Plan of the corporation in such other state in the event of such
merger.

         17. AMENDMENT OF THE PLAN. The Board may at any time, and from time to
time, amend this Plan in any respect, except that (a) if the approval of any
such amendment by the shareholders of the Company is required by Section 423 of
the Code or by Rule 16b-3 under the Exchange Act, such amendment shall not be
effected without such approval, and (b) in no event may any amendment be made
which would cause the Plan to fail to comply with Section 16 of the Exchange Act
and the rules promulgated thereunder, as in effect from time to time, or Section
423 of the Code.

         18. INSUFFICIENT SHARES. In the event that the total number of shares
of Common Stock specified in elections to be purchased under any Offering plus
the number of shares purchased under previous Offerings under this Plan exceeds
the maximum number of shares issuable under this Plan, the Board or the
Committee will allot the shares then available on a pro rata basis.

                                     Page 5
<PAGE>

         19. TERMINATION OF THE PLAN.  This Plan may be terminated at any
time by the Board.  Upon termination of this Plan all amounts in the accounts of
participating employees shall be promptly refunded.

         20. GOVERNMENTAL REGULATIONS. The Company's obligation to sell and
deliver Common Stock under this Plan is subject to listing on a national stock
exchange or quotation on the Nasdaq National Market and the approval of all
governmental authorities required in connection with the authorization, issuance
or sale of such stock.

         The Plan shall be governed by Vermont law except to the extent that
such law is preempted by federal law.

         The Plan is intended to comply with the provisions of Rule 16b-3
promulgated under the Securities Exchange Act of 1934. Any provision
inconsistent with such Rule shall to that extent be inoperative and shall not
affect the validity of the Plan.

         21. ISSUANCE OF SHARES.  Shares may be issued upon exercise of an
Option  from  authorized  but  unissued  Common  Stock,  from shares held in the
treasury of the Company,  or from any other proper source.

         22. NOTIFICATION UPON SALE OF SHARES. Each employee agrees, by entering
the Plan,  to promptly  give the  Company  notice of any  disposition  of shares
purchased  under the Plan where such  disposition  occurs within two years after
the date of grant of the Option pursuant to which such shares were purchased.

         23. EFFECTIVE DATE AND APPROVAL OF SHAREHOLDERS. The Plan shall take
effect upon approval by the shareholders of the Company as required by Rule
16b-3 under the Exchange Act and by Section 423 of the Code, which approval must
occur within twelve months of the adoption of the Plan by the Board.

         Adopted by the Board of Directors on September 18, 1995.

         Approved by the stockholders on September 27, 1995.

         Amended by the Board of Directors on October 16, 1995, which amendment
         did not require the approval of the stockholders.
