              Notes to Consolidated Condensed Financial Statements
                           September 30, 1998 and 1997
                                   (Unaudited)

1.  General:

The Consolidated Condensed Financial Statements as of September 30, 1998, and
for the three and nine months ended September 30, 1998 and 1997 are unaudited.
In the opinion of management, all adjustments, consisting of normal recurring
accruals, necessary for the fair presentation of the consolidated financial
position and results of operations and cash flows for the periods presented have
been included. Results for the interim periods are not necessarily indicative of
results that may be expected for the full year.

These Consolidated Condensed Financial Statements should be read in conjunction
with the consolidated financial statements and notes included in the Annual
Report on Form 10-K of Healthdyne Information Enterprises, Inc. ("HIE" or the
"Company") for the year ended December 31, 1997, as well as the supplemental
consolidated financial statements and notes included in the Form 8-K of HIE
dated June 1, 1998 which give retroactive effect to the merger with HUBLink,
Inc. ("HUBLink") which was accounted for as a pooling of interests as discussed
in Note 2.

2.  Merger:

On May 12, 1998, the Company completed a stock-for-stock merger (the "Merger")
through a wholly-owned subsidiary with HUBLink, a privately-held integration
software tool company. In connection with the Merger, the Company issued an
aggregate of 2.8 million shares of its Common Stock. The business combination
has been accounted for as a pooling of interests and, accordingly, the
consolidated financial statements for periods prior to the Merger have been
restated to include the accounts and results of operations of HUBLink. In
addition, the Company issued 100,000 shares of its Common Stock to a financial
advisor, which was engaged by HUBLink to assist with possible business
combinations.

The results of operations previously reported by the separate enterprises prior
to the combination and the combined amounts included in the accompanying
consolidated condensed financial statements are summarized below:

Company's revenue for the nine months ended September 30, 1998, or the three
months ended September 30, 1998 and 1997. One distributor accounted for 14% of
the Company's revenue for the three months ended September 30, 1998. No single

4. Earnings (Loss) Per Share of Common Stock:

On December 31, 1997, the Company adopted Statement of Financial Accounting
Standards No. 128, Earnings Per Share ("SFAS 128"), which prescribes the
calculation methodology and financial reporting requirements for basic and
diluted earnings per share. Basic earnings (loss) per common share available to
common shareholders are based on the weighted average number of common shares
outstanding. Diluted earnings (loss) per common share available to common
shareholders are based on the weighted average number of common shares
outstanding and dilutive potential common shares, such as dilutive stock
options. All prior period net earnings (loss) data presented in these
Consolidated Condensed Financial Statements have been restated to conform to the
provisions of SFAS 128.

5. Line of Credit:

The Company negotiated a new $5.0 million line of credit from a bank in
mid-August 1998, of which $2.2 million was available on September 30, 1998. The
line of credit is for a one year term, with borrowings bearing interest at the
bank's prime rate plus 1%. The Company plans to maintain the $5.0 million line
of credit for unanticipated needs and financial flexibility. Based on its
current business plan and business model projections, the Company believes that
currently available cash, anticipated cash flow from operating activities,
especially the collection of accounts receivable, and cash available from the
line of credit mentioned above will be sufficient to meet the Company's capital
requirements for at least the next twelve months and for the foreseeable future.

6. Recent Accounting Pronouncements:

     Revenue Recognition
         On January 1, 1998, the Company adopted Statement of Position 97-2,
     Software Revenue Recognition, issued by the Accounting Standards Executive
     Committee in October 1997, effective for financial statements for fiscal
     years beginning after December 15, 1997. The implementation of this
     statement has not had a material impact on the Company's unaudited
     Consolidated Condensed Financial Statements.

     Comprehensive Income
         On January 1, 1998, the Company adopted Statement of Financial
     Accounting Standards No. 130, Reporting Comprehensive Income, issued by the
     Financial Accounting Standards Board ("FASB") in September 1997, effective
     for fiscal years beginning after December 15, 1997. Comprehensive income
     includes all changes in equity during a period except those resulting in
     investments by owners and distributions to owners. The implementation of
     this statement has had no impact on the Company's unaudited Consolidated
     Condensed Financial Statements. Comprehensive income for the Company is 
     represented only by Net Income.

     Other
         The Company continues to evaluate the requirements of Statement of
     Financial Accounting Standards No. 131, Disclosures about Sements of an

Overview

Healthdyne Information Enterprises, Inc. ("HIE" or the "Company") was
incorporated in Georgia on June 15, 1994 and was a wholly-owned subsidiary of
Healthdyne, Inc. ("Healthdyne") until November 6, 1995, at which time Healthdyne
distributed all of the outstanding shares of HIE to Healthdyne's shareholders
(the "Spin-Off"). HIE's common stock is publicly traded on the Nasdaq National
Market under the symbol "HDIE." The Company provides software tools and services
to achieve the enterprise-wide integration of information.


                                       7

The Company generates revenue from licensing integration software tools and
providing integration services, such as education, consulting, project
management, information integration, technology-driven re-design, software
maintenance, implementation and expert-sourcing.

Software licenses are generally granted on a perpetual basis for a one-time,
up-front fee. A standard per-student amount is charged for education classes.
Consulting services are generally provided for a fixed fee based on estimated
hours of service to be provided at standard hourly rates. Project management,
information integration, technology-driven re-design and implementation fees are
generally based on actual hours of service at standard hourly rates. Software
maintenance agreements are generally one-year renewable service contracts for a
prepaid standard fee. Expert-sourcing agreements are generally multiple-year
renewable service contracts for a negotiated monthly fee.

On May 12, 1998, the Company completed a stock-for-stock Merger through a
wholly-owned subsidiary with HUBLink, a privately-held integration software tool
company. In connection with the Merger, the Company issued an aggregate of 2.8
million shares of its Common Stock. The business combination has been accounted
for as a pooling of interests and, accordingly, the consolidated financial
statements for periods prior to the Merger have been restated to include the
accounts and results of operations of HUBLink. In addition, the Company issued
100,000 shares of its Common Stock to a financial advisor, which had been
engaged by HUBLink to assist with possible business combinations.

On December 31, 1997, the Company exercised its option to acquire the remaining
50% ownership interest of Criterion Health Strategies, Inc. ("CHS") it did not
already own. CHS licenses the Criterion data integration software tool and
provides project management, information integration and technology-driven
re-design services. Since HIE did not have a majority ownership interest in CHS
in 1997 and prior years, the operating results of CHS were not included with the
Company's consolidated operating results. HIE's share of CHS' operating results
for 1997 are presented as Losses of Affiliate in the accompanying Consolidated
Condensed Statements of Operations. CHS's operating results were combined with
the Company's beginning on January 1, 1998.

In the fourth quarter of 1997, the Company redefined its strategic direction as
The Integration Solutions Company and focused on providing software tools and
services to achieve the enterprise-wide integration of information. Prior to
making this shift in strategic direction, the Company sold and distributed
certain proprietary and third-party clinical workstation tools including, among
others, the Clinical Assessment and Support System ("CASS"), Document Image
Management, Workflow Management, Intranet and Internet Workflow Management,
Teleradiology Computer Systems and Clinical Image Management tools. The Company
no longer actively sells and distributes the software tools referred to in the
preceding sentence, since such tools are outside the scope of the Company's
redefined strategic direction referred to above. 


                                       8
<PAGE>   9

In addition, effective November 21, 1997, HIE combined the operations of its
three subsidiaries (CHS, Integrated Healthcare Solutions, Inc. and Healthcare
Communications, Inc.) with the parent company under a functional organization
structure, i.e., sales, service, research and development and finance. Prior to
that time, each subsidiary operated as an independent, but interrelated, entity
referred to by the Company as an Entrepreneurial Business Unit. As of June 30,
1998, these three subsidiaries had been merged with and into the Company. The
Company changed to the present organizational structure in an attempt to be more
responsive to the marketplace and to streamline operations. The Company believes
that the current organizational structure will expand the depth and breadth of
its integration software tool distribution capability, improve the productivity
of its integration software tool development efforts, enhance the efficiency and
effectiveness of its customer service operations and eliminate duplicate efforts
throughout the organization.

The Company has implemented a Year 2000 compliance program designed to ensure
that the Company's computer systems and applications will function properly
beyond 1999. The Company believes that it has allocated adequate resources for
this purpose and expects its Year 2000 conversions to be completed on a timely
basis.

         Internal IT & Non-IT Systems - The Company is in the process of
         implementing new software for its accounting, internal network,
         timekeeping, and purchasing functions to better manage the growth of
         its business. Representations made by software vendors for these
         systems, including Year 2000 compliance, will be validated at the
         completion of that implementation which is expected to be early 1999.
         Non-IT systems, such as telecommunications systems, as well as existing
         IT systems are being assessed currently.

         Third Parties - The Company has material relationships with third
         parties whose Year 2000 compliance is being assessed by way of
         questionnaire. These third parties include, but are not limited to,
         banks, payroll processing vendors, and telecommunications vendors. The
         Company expects the assessment to be complete in early 1999 and will
         take the necessary action to minimize the Year 2000 non-compliance risk
         with respect to third parties including changing to vendors who are
         Year 2000 compliant or installing internal IT systems.

         Customers and Distributors - A failure in a customer's system could
         result in a claim for substantial damages against the Company,
         regardless of the Company's responsibility for such failure. The
         Company attempts to limit by contract, both with its customers and with
         the parties that license technology to the Company, its liability for
         damages arising in rendering its products and services. Despite this
         precaution, there can be no assurance that the limitations of
         liabilities set forth in its contracts would be enforceable or would
         otherwise protect the Company from liability for damages. There can be
         no assurance that the Company will be able to obtain or maintain
         insurance coverage for such liabilities, that such coverage will
         continue to be available on acceptable terms, or that such coverage
         will be available in amounts to cover one or more large claims. The
         assertion of claims against the Company that exceed available insurance
         coverage, or changes in the Company's insurance policies, including
         premium increases or the imposition of large deductible or co-insurance
         requirements, could have a material adverse effect on the Company's
         business, financial condition and results of operation. Furthermore,
         litigation, regardless of its outcome, could result in substantial cost
         to the Company and divert management's attention from the Company's
         operations. Any contract liability claim or litigation against the
         Company could, therefore, have a material adverse effect on the
         Company's business, financial condition or results of operations. The
         Company is in the process of evaluating the Year 2000 readiness of all
         products available currently or previously sold to customers and
         distributors. The Company expects this assessment to be complete in
         mid-1999.

The Company is in the final stages of development of contingency plans, which 
are expected to be implemented by mid-1999.

In light of its compliance efforts, the Company does not believe that the Year
2000 issue will materially adversely affect operations or results of operations,
and does not expect implementation to have a material impact on the Company's
financial statements. However, there can be no assurance that the Company's
systems will be Year 2000 compliant prior to December 31, 1999, or that the
failure of any such system 


                                       9
<PAGE>   10

will not have a material adverse effect on the Company's business, operating
results and financial condition. In addition, to the extent the Year 2000
problem has a material adverse effect on business, operations or financial
condition of third parties with whom the Company has material relationships,
such as vendors, suppliers and customers, the Year 2000 problem could have a
material adverse effect on the Company's business, results of operations and
financial condition.

The Company expects the following external factors to affect the market for
integration software tools and integration services in future years: (1) the
continued consolidation of enterprises within various industries to achieve
economies of scale; (2) the growing importance of information for the survival
and prosperity of various enterprises; (3) the increasing complexity of
information technology; and (4) the year 2000 issue referred to above.

Software revenue is generally recognized upon shipment and the performance of
certain other criteria in accordance with Statement of Position ("SOP") 97-2,
"Software Revenue Recognition" in 1998 and SOP 91-1, "Software Revenue
Recognition" in 1997. Service revenue is recognized as the work is performed or,
in the case of a fixed-fee contract, on the percentage of completion basis, even
though some services are prepaid.

The Company's Consolidated Condensed Balance Sheets include assets designated as
purchased software and capitalized software development costs. Purchased
software includes the cost of purchased integration software tools and the cost
of software acquired in connection with business combinations. It also includes
the cost of licenses to use, embed and sell software tools developed by others.
Certain costs of HIE proprietary software developed internally are capitalized
in accordance with generally accepted accounting principles. The costs of
individual software tools are being amortized ratably based on the projected
revenue associated with the related software or on a straight-line basis over
not more than five years, whichever method results in a higher level of annual
amortization.

The excess of cost over net assets of businesses acquired (goodwill) is being
amortized over a period of fifteen years. At each balance sheet date, the
Company assesses the recoverability of this intangible asset by determining
whether the amortization of the goodwill balance over its remaining life can be
recovered through undiscounted future operating cash flows of the acquired
operation. The amount of goodwill impairment, if any, is measured based on
projected discounted future operating cash flows using a discount rate
reflecting the Company's average cost of funds.

Comparison of Three Months Ended September 30, 1998 and 1997

         Revenue. Total revenue was $7.3 million for the three months ended
September 30, 1998 compared to $4.5 million for the three months ended September
30, 1997, an increase of 62%. The increase of $1.5 million, or 80%, in software
revenue was primarily due to an increase in Cloverleaf integration engine and
OM3 message broker software license fee revenue. The increase of $1.3 million or
49%, in services revenue was due primarily to higher service personnel
productivity as well as an increase in the number of service personnel. HIE
added eleven new distributors in the third quarter of 1998.

         Cost of revenue. Cost of revenue includes, among other things,
compensation of service personnel, travel and software royalties and
amortization. The cost of revenue was $1.9 million for the three months ended
September 30, 1998 compared to $1.6 million for the three months ended September
30, 1997, an increase of 18%. However, as a percentage of revenue, cost of
revenue decreased to 26% from 36% primarily due to the sub-licensing by the
Company of significantly less third-party software tools, as well as an increase
in the level of service personnel productivity in the third quarter of 1998
compared to the third quarter of 1997. Third-party software tools, such as
imaging, workflow and COLD, typically have a higher cost of revenue than
proprietary software tools, such as the Cloverleaf integration engine and OM3
message broker and the EMerge enterprise master person index software tool. The
Company discontinued the marketing, sale and distribution of imaging, workflow,
COLD and certain other software tools that no longer fit its redefined strategic
direction in the fourth quarter of 1997.

         Gross profit. The Company's gross profit was $5.4 million for the three
months ended September 30, 1998 compared to $2.9 million for the three months
ended September 30, 1997, an increase of 87%. The increased gross profit in the
third quarter of 1998 was due to the significant increase in the more profitable
Cloverleaf integration engine and OM3 message broker software license fee
revenue discussed above, as well as the higher level of service personnel
productivity also discussed above.

         Sales and marketing. Sales and marketing expense includes, among other
things, compensation of sales and marketing personnel, sales commissions, travel
and advertising. Sales and marketing expense was $1.7 million for the three
months ended September 30, 1998 compared with $1.3 million for the three months
ended September 30, 1997. The increase of $419,000 in sales and marketing
expense between the periods was due primarily to the increase in sales personnel
costs associated with increased sales staffing. The decrease in sales and
marketing expense from 29% of revenue in the three months ended September 30,
1997 to 24% in the three months ended September 30, 1998 was due to the
significant increase in software and services revenue discussed above.

<PAGE>   13

         Research and development. Research and development expense includes,
among other things, compensation of research and development personnel,
depreciation and lease expense of research and development equipment and travel.
Research and development expense was $930,000 or 13% of revenue for the three
months ended September 30, 1998 compared to $780,000 or 17% of revenue for the
three months ended September 30, 1997, an increase of 19%. Cash expenditures for
research and development increased $203,000, while the level of capitalization
of internally developed software increased to 21% in the third quarter of 1998
from 20% in the third quarter of 1997, due primarily to increased staffing for
various research and development projects.

         General and administrative. General and administrative expense
includes, among other things, compensation of finance, human resources and
administrative personnel, goodwill amortization, office rent and insurance.
General and administrative expense was $1.6 million or 22% of revenue for the
three months ended September 30, 1998, compared to $1.3 million or 28% of
revenue for the three months ended September 30, 1997, an increase of 28%. The
increase was due primarily to increased recruiting and outside contractor costs
associated with the Company's increased revenue and personnel growth.

         Interest income (expense), net. Net interest expense was $29,000 for
the three months ended September 30, 1998 compared to net interest income of
$12,000 for the three months ended September 30, 1997, representing a change of
$41,000. The change in net interest income (expense) is due primarily to a
decrease in interest income resulting from lower cash balances and increased
short-term borrowings.

         Income tax (expense) benefit. The Company did not record any income tax
benefit for the three months ended September 30, 1998 because allowable
carrybacks exceeded income. The Company recorded an income tax expense of
$42,000 for the three months ended September 30, 1997 based on management's
belief at the time that the Company would generate taxable income above the net
operating loss carryforward benefits for the year ended December 31, 1997.


Comparison of Nine Months Ended September 30, 1998 and 1997

         Revenue. Total revenue was $19.1 million for the nine months ended
September 30, 1998 compared to $12.9 million for the nine months ended September
30, 1997, an increase of 48%. The increase of $3.3 million, or 68%, in software
revenue was primarily due to an increase in Cloverleaf integration engine and
OM3 message broker software license fee revenue, offset somewhat by a reduction
in third-party software tool revenue. The increase of $2.8 million, or 35%, in
services revenue was due primarily to higher service personnel productivity as
well as an increase in the 


                                       13

number of service personnel. HIE added twenty-five new distributors in the nine
months ended September 30, 1998.

         Cost of revenue. The cost of revenue was $5.6 million for the nine
months ended September 30, 1998 compared to $5.4 million for the nine months
ended September 30, 1997, an increase of 4%. As a percentage of revenue, cost of
revenue decreased to 29% from 42%, primarily due to the sub-licensing by the
Company of significantly less third-party software tools, as well as an increase
in the level of service personnel productivity in the nine months ended
September 30, 1998 compared to the nine months ended September 30, 1997. The
Company discontinued the marketing, sale and distribution of imaging, workflow,
COLD and certain other software tools that no longer fit its redefined strategic
direction in the fourth quarter of 1997.

         Gross profit. The Company's gross profit was $13.4 million for the nine
months ended September 30, 1998 compared to $7.5 million for the nine months
ended September 30, 1997, an increase of 78%. The increased gross profit in the
first nine months of 1998 was due to the significant increase in the more
profitable Cloverleaf integration engine and OM3 message broker software license
fee revenue discussed above, as well as the higher level of service personnel
productivity also discussed above.

         Sales and marketing. Sales and marketing expense was $4.8 million or
25% of revenue for the nine months ended September 30, 1998 compared to $4.2
million or 32% of revenue for the nine months ended September 30, 1997, an
increase of 14%. The increase in sales and marketing expense between the periods
was due primarily to the increase in sales personnel costs associated with
increased sales staffing, offset somewhat by lower marketing personnel costs. As
a percentage of revenue, sales and marketing decreased due to the significant
increase in software and services revenue discussed above.

         Research and development. Research and development expense was $2.8
million or 15% of revenue for the nine months ended September 30, 1998 compared
to $2.2 million or 17% of revenue for the nine months ended September 30, 1997,
an increase of 29%. Cash expenditures for research and development increased
$1.1 million between the two periods, while the level of capitalization of
internally developed software increased to 25% in the nine months ended
September 30, 1998 from 20% in the nine months ended September 30, 1997, due
primarily to increased staffing for various research and development projects.

         General and administrative. General and administrative expense was $4.3
million or 22% of revenue for the nine months ended September 30, 1998, compared
to $3.4 million or 27% of revenue for the nine months ended September 30, 1997,
an increase of 25%. The increase was due primarily to increased recruiting and
outside contractor costs associated with the Company's increased revenue and
personnel growth.

         Merger costs. Merger costs, which resulted from the Company's
acquisition of HUBLink, includes, among other things, investment banking, legal
and accounting fees, travel and severance costs. The total merger costs were
$1.1 million in the nine months ended September 30, 1998. The Company had
accrued for all of the anticipated merger costs in the second quarter, and
incurred merger-related transition costs of $67,000 in the quarter ended
September 30, 1998. The Company anticipates transition costs of approximately
$100,000 to be incurred during the next quarter.

         Losses of affiliate. Losses of affiliate, which resulted from the
Company's commitment to fund CHS, totaled $151,000 in the first nine months of
1997. CHS's operating results were consolidated with the Company's beginning on
January 1, 1998.

         Interest income (expense), net. Net interest expense was $67,000 for
the nine months ended September 30, 1998 compared to net interest income of
$81,000 for the nine months ended September 30, 1997, representing a change of
$148,000. The change in net interest income (expense) is due primarily to a
decrease in interest income resulting from lower cash balances and increased
short-term borrowings, some of which were repaid by the Company in the second
quarter.

         Income tax (expense) benefit. The Company recorded an income tax
expense of $144,000 for the nine months ended September 30, 1998 based on the
inability of a profitable subsidiary to utilize the group's net operating losses
for state reporting purposes. The Company recorded an income tax benefit of
$57,000 for the nine months ended September 30, 1997 based on the projected
effective tax rate for the year ended December 31, 1997.

Liquidity and Capital Resources

         The Company had working capital of $4.7 million at September 30, 1998
compared to $2.7 million at December 31, 1997. Cash decreased $5.9 million
during the nine months ended September 30, 1998 compared to a $2.7 million
decrease during the nine months ended September 30, 1997 for the reasons
discussed below.

         Net cash used in operating activities totaled $3.3 million for the nine
months ended September 30, 1998 compared to $1.9 million for the nine months
ended September 30, 1997. The $1.4 million total variance between the two
periods is primarily attributable to an increase in accounts receivable offset
by the increased cash flow resulting from the net income recorded during the
nine months ended September 30, 1998 compared to the net loss recorded during
the nine months ended September 30, 1997 and increased accounts payable.

         Net cash used in investing activities was $1.5 million for the nine
months ended September 30, 1998 compared to $1.7 million for the nine months
ended September 30, 1997. The decrease was due primarily to a $350,000
investment in CHS in 


                                       15

February 1997 which was nonrecurring in 1998 and lower capital expenditures in
the nine months ended September 30, 1998, both offset somewhat by an increased
investment in software during the nine months ended September 30, 1998.

         Net cash used in financing activities was $1.1 million for the nine
months ended September 30, 1998 and net cash provided by financing activities
was $935,000 for the nine months ended September 30, 1997. Most of the variance
between the two periods is attributable to the payment of $3.3 million of debt
financing that matured on January 2, 1998. In addition, HUBLink obtained
proceeds of $1.2 million from the issuance of common stock during the nine
months ended September 30, 1997.

         The Company negotiated a new $5.0 million line of credit from a bank in
mid-August 1998, of which $2.2 million was available on September 30, 1998. The
line of credit is for a one year term, with borrowings bearing interest at the
bank's prime rate plus 1%. The Company plans to maintain the $5.0 million line
of credit for unanticipated needs and financial flexibility. Based on its
current business plan and business model projections, the Company believes that
currently available cash, anticipated cash flow from operating activities,
especially the collection of accounts receivable, and cash available from the
line of credit mentioned above will be sufficient to meet the Company's capital
requirements for at least the next twelve months and for the foreseeable future.

Recent Accounting Pronouncements

         On January 1, 1998, the Company adopted Statement of Position 97-2,
Software Revenue Recognition, issued by the Accounting Standards Executive
Committee, and Statement of Financial Accounting Standards No. 130, Reporting
Comprehensive Income, issued by the Financial Accounting Standards Board. The
Company continues to evaluate the requirements of Statement of Financial
Accounting Standards No. 131, Disclosures about Segments of an Enterprise and
Related Information, which does not apply to interim periods in the year of
adoption.
