                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     THREE MONTHS AND THE NINE MONTHS ENDED
                               DECEMBER 31, 1997
                                  (UNAUDITED)
 
 1. BASIS OF PRESENTATION
 
     In the opinion of management, the accompanying consolidated financial
statements include all adjustments necessary for a fair presentation of the
financial position of COHR Inc. ("COHR") and subsidiaries (collectively, the
"Company"), and the results of its operations and its cash flows for the interim
periods presented. Although COHR believes that the disclosures in these
consolidated financial statements are adequate to make the information presented
not misleading, certain information and footnote disclosures normally included
in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to the rules and
regulations of the Securities and Exchange Commission. Results of operations for
the interim periods are not necessarily indicative of results to be expected for
any other interim period or for the full year.
 
     The consolidated financial statements for the three-month and nine-month
periods ended December 31, 1997 and December 31, 1996 (restated) are unaudited
and should be read in conjunction with the consolidated financial statements and
notes thereto included in COHR's Annual Report on Form 10-K for the year ended
March 31, 1997.
 
     Consolidation of Subsidiaries -- The Company's financial statements include
the activity of all of its wholly owned subsidiaries over which the Company has
direct or indirect or indirect unilateral and perpetual control. All
intercompany transactions have been eliminated in consolidation.
 
     Net Income (Loss) Per Common Share -- Basic loss per share for the
three-month and nine-month periods ended December 31, 1997 has been calculated
in accordance with the Financial Accounting Standards Board's Statement of
Financial Accounting Standard No. 128 (SFAS No. 128) "Earnings Per Share." The
calculation of earnings per share for earlier periods has been restated in
accordance with SFAS No. 128. The calculation of fully diluted loss per share is
not presented as such amounts would be antidilutive.
 
 2. SUBSEQUENT EVENT
 
     Subsequent to December 31, 1997, the Company acquired certain assets of a
business with operations similar to those of the Company. The purchase price was
$750,000, subject to certain future adjustments, with $300,000 payable on
February 1, 1998, which was paid by the Company. The remaining balance is
payable in varying annual installments through February 1, 2002.
 
 3. SPECIAL CHARGES
 
     Special charges consist of a write-off of approximately $2.6 million of
goodwill dated to the acquisition of one of its operating units in accordance
with Statement of Financial Accounting Standards No. 121 and legal, audit and
related costs resulting from the special review conducted at the direction of
the Board of Directors.
 
 4. RESTATEMENT
 
     Subsequent to the issuance of the Company's fiscal 1997 consolidated
financial statements, the Company's management determined that certain equipment
and software sales were prematurely recorded and that certain liabilities were
understated. As a result, the accompanying consolidated balance sheet as of
March 31, 1997 and the statements of operations and cash flows for the three and
nine months ended December 31, 1996 have been restated from the amounts
previously reported to reverse these sales and to record the appropriate
liabilities.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
GENERAL
 
     The Company is a leading national outsourcing service organization
providing equipment servicing, group purchasing and other services to hospitals,
integrated health systems and alternate site providers.
 
RESTATEMENT OF PRIOR PERIOD FINANCIAL STATEMENTS
 
     The Company has concluded that a restatement of previously reported
financial statements for the first two quarters of fiscal year 1998 and for
fiscal year 1997 is appropriate based upon management's determination that
certain equipment and software sales were prematurely recorded and that certain
liabilities were understated. Please see Note 4 to the Consolidated Financial
Statements for the Three and Nine Months Ended December 31, 1997.
 
RESULTS OF OPERATIONS
 
     NINE MONTHS ENDED DECEMBER 31, 1997 VERSUS NINE MONTHS ENDED DECEMBER 31,
1996 AS RESTATED
 
     Revenues -- The Company's revenues for the nine months ended December 31,
1997 totaled $75.2 million, an increase of $13.4 million or 21.7% over revenues
of $61.8 million for the nine months ended December 31, 1996. Of the $13.4
million increase in revenues, $13.0 million is primarily the result of
internally generated growth in COHR MasterPlan.
 
     Direct Operating Expenses -- The Company's direct expenses for the nine
months ended December 31, 1997 totaled $61.6 million which represented an
increase of $16.8 million or 37.5% over the nine months ended December 31, 1996
total of $44.8 million. Direct operating expenses as a percentage of revenues
for the nine months ended December 31, 1997 increased to 81.9% from 72.5% for
the nine months ended December 31, 1996. Factors contributing to the increase
include growth in the number of sales and service employees and related employee
costs, the outsourcing of a greater number of services provided to customers,
and an increase in customer rebate accruals.
 
     Gross Margin. The Company's gross margin for the nine months ended December
31, 1997 totaled $13.6 million, a decrease of $3.4 million or 20.0% over the
nine months ended December 31, 1996 total of $17.0 million. Gross margin as a
percentage of revenues decreased to 18.1% for the nine months ended December 31,
1997 from 27.5% for the nine months ended December 31, 1996. Factors
contributing to the decrease in gross margin include the increased expenses
identified in the discussion of divested operating expenses above.
 
     Selling, General and Administrative Expenses. The Company's selling,
general and administrative expenses for the nine months ended December 31, 1997
totaled $24.8 million, an increase of $11.6 million or 87.9% over the nine
months ended December 31, 1996 total of $13.2 million. As a percentage of
revenues, selling, general and administrative expenses increased during the nine
months ended December 31, 1997 to 33.0% from 21.4% during the nine months ended
December 31, 1996. Included within the increase in selling, general and
administrative expenses is a $4.3 million increase in the allowance for doubtful
accounts. Other factors contributing to the increase include increases in the
number of support personnel, facility expenses and other expenses incurred to
generate new business.
 
     Operating Income (Loss). The Company's operating loss for the nine months
ended December 31, 1997 totaled $11.1 million, a decrease of $14.9 million over
the nine months ended December 31, 1996 operating income of $3.8 million. The
operating loss as a percentage of revenues for the nine months ended December
31, 1997 decreased to a 14.8% charge as compared to a 6.1% return for the nine
months ended December 31, 1996. The operating loss can be attributed to the
adjustments and other expenses identified in the discussion of direct operating
expenses and selling, general and administrative expenses above.
 
     Special Charges. The Company recorded special charges of $4.1 million
before taxes for the nine months ended December 31, 1997. The entirety of these
charges were recorded in the third quarter. Of this total, $2.6 million was a
write-off of goodwill related to the acquisition of one of the Company's
operating
 
                                        8

divisions in accordance with SFAS 121, and $1.5 million was for accrual of
certain other expenses, including non-recurring costs associated with the
Board's special review and other items. See Note 4 to the Consolidated Financial
Statements for the Three and Nine Months Ended December 31, 1997.
 
     Provision for Income Taxes (Benefit). The Company's income tax benefit for
the nine months ended December 31, 1997 totaled $3.1 million, a decrease of $4.8
million in tax over the nine months ended December 31, 1996 provision for income
taxes of $1.7 million, due to the decrease in pre-tax income for the period. The
Company's effective tax (benefit) rate was (21.2%) for the nine months ended
December 31, 1997 and 40.0% for the nine months ended December 31, 1996. The
effective benefit rate for the nine months ended December 31, 1997 was lower
than it would have otherwise been due to the fact that the Company is unable to
utilize a tax benefit of $1.9 million due to limitations on the carryback of net
operating losses.
 
     Net Income (Loss). The Company's net loss for the nine months ended
December 31, 1997 totaled $11.4 million, a decrease of $14.0 million over the
nine months ended December 31, 1996 net income of $2.6 million. As a percentage
of revenues, net income (loss) decreased to a 15.2% charge in the nine months
ended December 31, 1997 from a 4.2% return in the nine months ended December 31,
1996.
 
     THREE MONTHS ENDED DECEMBER 31, 1997 VERSUS THREE MONTHS ENDED DECEMBER 31,
1996 AS RESTATED
 
     Revenues -- The Company's revenues for the three months ended December 31,
1997 totaled $24.4 million, an increase of $4.2 million or 20.8% over revenues
of $20.2 million for the three months ended December 31, 1996. Of the $4.3
million increase in revenues, $4.2 million is primarily the result of internally
generated growth in COHR MasterPlan.
 
     Direct Operating Expenses -- The Company's direct expenses for the three
months ended December 31, 1997 totaled $20.2 million which represented an
increase of $5.3 million or 35.6% over the three months ended December 31, 1996
total of $14.9 million. Direct operating expenses as a percentage of revenues
for the three months ended December 31, 1997 increased to 82.8% from 73.8% for
the three months ended December 31, 1996. The primary factors contributing to
the increase include growth in the number of sales and service employees and
related employee costs and the outsourcing of a greater number of services
provided to customers.
 
     Gross Margin. The Company's gross margin for the three months ended
December 31, 1997 totaled $4.2 million, a decrease of $1.1 million or 20.8% over
the three months ended December 31, 1996 total of $5.3 million. Gross margin as
a percentage of revenues decreased to 17.2% for the three months ended December
31, 1997 from 26.2% for the three months ended December 31, 1996.
 
     Selling, General and Administrative Expenses. The Company's selling,
general and administrative expenses for the three months ended December 31, 1997
totaled $13.7 million, an increase of $9.2 million or 204.4% over the three
months ended December 31, 1996 total of $4.5 million. As a percentage of
revenues, selling, general and administrative expenses increased during the
three months ended December 31, 1997 to 56.1% from 22.4% during the three months
ended December 31, 1996. Included within the increase in selling, general and
administrative expenses is a $3.9 million increase in the allowance for doubtful
accounts. Other factors contributing to the increase include increases in the
number of support personnel, facility expenses and other expenses incurred to
generate new business.
 
     Operating Income (Loss). The Company's operating loss for the three months
ended December 31, 1997 totaled $9.5 million, a decrease of $10.2 million over
the three months ended December 31, 1996 operating income of $762,000. The
operating loss as a percentage of revenues for the three months ended December
31, 1997 decreased to a 38.7% charge as compared to a 3.8% return for the three
months ended December 31, 1996. The operating loss can be attributed to the
adjustments and other expenses identified in the discussion of Direct Operating
Expenses and Selling, General and Administrative Expenses above.
 
     Special Charges. The Company recorded special charges of $4.1 million
before taxes for the three months ended December 31, 1997. Of this total, $2.6
million was a write-off of goodwill related to the acquisition of one of the
Company's operating divisions in accordance with SFAS 121 and $1.5 million was
for accrual of other expenses, including non-recurring costs associated with the
Board's special review and other

items. See Note 4 to the Consolidated Financial Statements for the Three and
Nine Months Ended December 31, 1997.
 
     Provision for Income Taxes (Benefit). The Company's income tax benefit for
the three months ended December 31, 1997 totaled $2.7 million, a decrease of
$3.1 million over the three months ended December 31, 1995 provision for income
taxes of $383,000, due to the decrease in pre-tax income for the period. The
Company's effective tax (benefit) rate was (20.1%) for the three months ended
December 31, 1997 and 40.0% for the three months ended December 31, 1996. The
effective benefit rate for the three months ended December 31, 1997 was lower
than it would have otherwise been due to the fact that the Company is unable to
utilize a tax benefit of $1.9 million due to limitations on the carryback of net
operating losses.
 
     Net Income (Loss). The Company's net loss for the three months ended
December 31, 1997 totaled $10.7 million, a decrease of $11.2 million over the
three months ended December 31, 1996 net income of $574,000. As a percentage of
revenues, net income (loss) was a 43.6% charge in the three months ended
December 31, 1997 compared to a 2.8% return in the three months ended December
31, 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company had working capital of $37.9 million and $49.9 million as of
December 31, 1997 and March 31, 1997 respectively. The Company had cash, cash
equivalents and short-term investments of $18.0 million as of December 31, 1997
as compared to $28.9 million as of March 31, 1997. The decrease in the amount of
cash, cash equivalents and short term investments during the first nine months
of fiscal year 1998 was primarily attributable to a net operating loss of $11.4
million (offset in part by noncash charges for depreciation, amortization and
provision for losses on accounts receivable of $5.9 million), capital
expenditures and payment for acquired assets of businesses of $3.2 million and a
repayment of long-term debt of $2.2 million.
 
     The Company allowed its revolving credit line to expire and has not sought
a renewal thereof. The Company has not paid dividends since its initial public
offering in February of 1996.
 
INFLATION
 
     The Company believes that its operations have not been materially adversely
affected by inflation. The Company expects that salary and wage increases for
its skilled staff will continue to be higher than average wage increases, as is
common in the Company's industry.
 
ADDITIONAL FACTORS AFFECTING OPERATING RESULTS
 
     In addition to the Factors Affecting Operating Results set forth in the
Company's latest Form 10-K Annual Report for the Year Ended March 31, 1997,
please note the following:
 
          1. Restatement of Financial Statements. The Company will restate its
     financial statements for the fiscal year ended March 31, 1997 and the first
     two quarters of the current fiscal year. This restatement relates primarily
     to management's determination that certain equipment and software sales
     were prematurely recorded and that certain liabilities and reserves were
     understated. Management is not able to predict what effects the restatement
     may have on the future operations, relationships with customers or on the
     market price of the Company's common stock.
 
          2. Dependence on Key Personnel. In its Form 10-K for the fiscal year
     ended March 31, 1997, the Company disclosed that it will depend in large
     part on the performance of a number of key employees, including Paul
     Chopra, its Chairman of the Board and Chief Executive Officer (CEO). The
     Company replaced Mr. Chopra in November of 1997 and, effective February 17,
     1998, replaced its Chief Financial Officer (CFO). The Company believes that
     it has secured qualified replacements but both individuals are not as
     familiar with the operations of the Company as their predecessors. The
     Company's success continues to depend to a certain significant degree upon
     continued contributions of its key management, sales and operational
     personnel and the Company's ability to retain and continue to attract
     highly skilled personnel. In light of the change in the CEO and CFO, the
     restatement of certain of its financial
 
                                       10
<PAGE>   11
 
     statements and the possibility of a sale of the Company, there can be no
     assurance that other key employees may not want to seek employment
     elsewhere. The failure of the Company to attract and retain key personnel
     would have a material adverse affect on the Company's business, operating
     results and financial condition.
 
          3. Future Operating Results. The Company has suffered certain setbacks
     during the past six months, including replacement of its CEO and CFO, the
     restatement of the 1997 financial statements and interim 1998 financial
     statements, and a drop in the price of its common stock. The Company also
     continues to face certain challenges more specific to its operations
     including (1) shifting its strategic focus from acquiring compatible
     business to running its existing business sufficiently and profitably; (2)
     managing existing customers' perceptions of the Company's continued
     viability and refocusing on the high levels of customer service required to
     develop new customers and retain existing customers; (3) combating employee
     turnover, particularly in light of declines in the market value of the
     Company's common stock (the value of which often plays a role in
     compensation of employees); and (4) reducing costs and increasing
     efficiencies. There can be no assurance that the Company will successfully
     meet these or other operating challenges or that the Company's operating
     plans ultimately will be successful. A failure with respect to the
     foregoing could have a material adverse effect on the Company.
