Notes To Financial Statements (unaudited):

1. The unaudited financial statements presented herein have been prepared in
accordance with the instructions to Form 10-Q and do not include all of the
information and note disclosures required by generally accepted accounting
principles. These statements should be read in conjunction with the financial
statements and notes thereto for the year ended December 31, 2004 included in
the Company's Form 10-K filed January 31, 2005. The unaudited financial statements
presented herein have not been audited by our Independent Registered Public
Accounting Firm in accordance with the standards of the Public Company Accounting
Oversight Board (United States), but in the opinion of management such financial
statements include all normal recurring adjustments necessary to present fairly
the Company's financial position, results of operations and cash flow.

2. During 2005, the Company made certain reclassifications to amounts in its
balance sheet. The September 30, 2005 deferred taxes and tax reserves of $13,447
thousand are now recorded as current and the corresponding amount of $13,992
thousand at December 31, 2004 has been reclassified for comparative purposes.

3. The Company follows the provisions of Statement of Financial Accounting
Standards No. 128 (SFAS 128), Earnings per Share. SFAS 128 requires reporting
both basic and diluted earnings per share (EPS). The Company has no common share
equivalents such as preferred stock, warrants or stock options which would
dilute EPS. Thus, EPS is computed by dividing net income by the weighted average
number of common shares outstanding during the applicable period.

5. At September 30, 2005 the Company's marketable securities had a fair market
value of $261,436,843 which includes a gross unrealized gain of $21,373,908 and
a gross unrealized loss of $2,458,455. The gross unrealized loss is composed of
6 equities with an original cost of $33,390,605 and a fair market value of
$30,932,150. These 6 equities have been in an unrealized loss status for less
than 9 months. The Company considered the effect of rising interest rates and
the issuers' current financial position in order to reach its conclusion that
these impairments are temporary at September 30, 2005. The details are as
follows:



|Descriptionof Securities | Fair MarketValue | UnrealizedLoss
|------------------------ | ---------------- | --------------
|                         |                  |               
|3 common equities        | $9,288,900       | $1,326,775    
|3 preferred equities     | $21,643,250      | $1,131,680    

6. The Company follows the provisions of Statement of Financial Accounting
Standards No. 131 (SFAS 131), Disclosure About Segments of an Enterprise and
Related Information. Based on the criteria set forth in SFAS 131 the
Company currently operates in one operating segment, medical software and
services. The Company derives substantially all of its operating revenue from
the sale and support of one group of similar products and services. All of the
Company's assets are located within the United States. During the first 9 months
of 2005, 90% of our operating revenue was derived from the United States,
9% from Canada and 1% from other countries, all of which is similar to prior years.

7. During the month of February from 1997 through 2003, the Company offered and
sold shares of its common stock to its staff members in a manner which may not
have complied with the registration requirements of certain federal and state
securities laws. During the 4th quarter of 2004 the Company made a recision offer
to these individuals so as to extinguish its liability, if any, for these potential
securities law violations. None of these individuals accepted the recision offer.

Prior to the 4th quarter of 2004 the shares subject to recision rights were
considered and treated as redeemable common stock for financial accounting purposes
until such time as the recision rights terminated or were exercised. Therefore the
recision amount and the related shares were classified as Temporary Equity. In late
December, when the recision offer expired, the Company transferred the
recision amount and related shares from Temporary Equity to Shareholder Equity.

At September 30, 2005, one customer owed $4.2 million or 13% of the accounts

because no payroll tax withholding was outstanding at December 31, 2004

During the first 9 months taxes payable decreased by $1.7 million due primarily
to additional state tax payments in 2005.

During the first 9 months accrued expenses increased by a nominal $0.8 million.
The primary activity therein consisted of the payment of $21.3 million in bonuses
applicable to 2004, offset by the accrual of $21.4 million in bonus expenses

Liquidity and Capital Resources:

At September 30, 2005 the Company's cash, cash equivalents and marketable securities
totaled $271.2 million. Marketable securities consisted of preferred equities,
common equities and government notes which can easily be converted to cash.
During the first 9 months of 2005 cash flow from operations was $68.8 million,
cash flow used in investing was $28.4 million and cash flow used in financing was
$45.2 million. During the first 9 months of 2005 the payment of $52.0 million in dividends
to shareholders was the primary use of cash generated by operating activities.

MEDITECH has no long-term debt. Shareholder equity at September 30, 2005 was $379.9 million.
Management anticipates additions to property, plant and equipment will continue,
including new facilities and computer systems for product development, sales and
marketing, implementation, service and administrative staff. Management believes
existing cash, cash equivalents and marketable securities together with funds
generated from operations will be sufficient to meet operating and capital expense
requirements for the foreseeable future.
