                    OCCUPATIONAL HEALTH + REHABILITATION INC
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)



1.  BASIS OF PRESENTATION

  The accompanying unaudited interim financial statements of Occupational Health
+ Rehabilitation Inc (the "Company") have been prepared in accordance with the
instructions to Form 10-Q and Rule 10.01 of Regulation S-X pertaining to interim
financial information and disclosures required by generally accepted accounting
principles.  The interim financial statements presented herein reflect all
adjustments (consisting of normal recurring adjustments) which, in the opinion
of management, are considered necessary for a fair presentation of the Company's
financial condition as of September 30, 1998 and results of operations for the
three and nine months ended September 30, 1998 and 1997.  The results of
operations for the nine months ended September 30, 1998 are not necessarily
indicative of the results that may be expected for a full year.

2.  NET LOSS PER COMMON SHARE

  In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share. Statement 128 replaced the calculation of primary and fully
diluted earnings per share with basic and diluted earnings per share.  Unlike
primary earnings per share, basic earnings per share excludes any dilutive
effects of options, warrants and convertible securities.  Diluted earnings per
share is very similar to the previously reported fully diluted earnings per
share.  There was no effect on previously reported net loss per common share
amounts due to the adoption of Statement 128.  For the nine months ended
September 30, 1998, for purposes of the net loss per common share calculation,
the net loss has been increased by $12,000  of preferred stock accretion.  The
effect of options, warrants, convertible preferred stock and a convertible note
payable is not considered as it would be anti-dilutive for the periods
presented.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS


OVERVIEW

  The Company specializes in occupational health care throughout the
Northeastern United States.  The Company develops and operates multidisciplinary
outpatient healthcare centers and provides on-site services to employers for the
prevention, treatment and management of work-related injuries and illnesses. The
Company operates the centers under management and submanagement agreements with
professional corporations that practice exclusively through such centers.
Additionally, the Company has entered into joint ventures with hospital-related
organizations to provide management and related services to the centers
established by the joint ventures.

  The Company is the surviving corporation of a merger (the "Merger") of
Occupational Health + Rehabilitation Inc ("OH+R") into Telor Ophthalmic
Pharmaceuticals, Inc ("Telor").  Pursuant to the Merger, the ophthalmic
pharmaceutical business of Telor ceased, and the business of the Company was
changed to the business of OH+R.

  The following table sets forth, for the periods indicated, the relative
percentages which certain items in the Company's consolidated statements of
operations bear to  revenue. The following information should be read in
conjunction with the consolidated financial statements and notes thereto
included elsewhere in this report. Historical results and percentage
relationships are not necessarily indicative of the results that may be expected
for any future period.

RESULTS OF OPERATIONS (DOLLAR AMOUNTS IN THOUSANDS)
---------------------                              

THREE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997
----------------------------------------------

Revenue

  Revenue increased 17% to approximately $5,753 in the three months ended
September 30, 1998 from approximately $4,913 in the three months ended September
30, 1997.  Of the approximately $840  increase in revenue in the three months
ended September 30, 1998 compared to the three months ended September 30, 1997,
approximately $1,257 related to centers acquired subsequent to September 30,
1997 and the remaining $255  related to additional volume at existing centers.
These amounts were offset by $672  of revenue which related primarily to the
Company's share of a partnership in which the Company sold its interest on
December 31, 1997.

Operating, General and Administrative Expenses

  Operating expenses increased 8%  to approximately $4,889 in the three months
ended September 30, 1998 from approximately $4,508  in the three months ended
September 30, 1997.  This increase was principally due to the acquisition and
development of additional centers.  As a percentage of  revenue, operating
expenses declined to 85% in the three months ended September 30, 1998 as
compared to 92% in the three months ended September 30, 1997.  The centers, in
the aggregate, continued to achieve profitability before general  and
administrative expenses during the third quarter of 1998 as individual centers
reached critical mass in terms of volume.

  General and administrative expenses increased 10% to approximately  $675 in
the three months ended September 30, 1998 from $611 in the three months ended
September  30, 1997.  The increase was the result of the Company's expanding its
corporate staff to support the growth in the centers and to support additional
business lines.  As a percentage of revenue, general and administrative expenses
approximated 12% in the three months ended both September 30, 1998 and 1997.

Depreciation and Amortization

  Depreciation and amortization expense increased 18% to approximately $194 in
the three months ended September 30, 1998 from approximately $165 in the three
months ended September 30, 1997.  The increase occurred primarily as a result of
the Company's having additional growth through center development and
acquisitions.  As a percentage of revenue, depreciation and amortization was 3%
in both the three months ended September 30, 1998 and 1997.

Interest Income

  Interest income is generated primarily from cash invested in highly liquid
funds with a maturity of three months or less.  Interest income decreased 53% to
approximately  $44 in the three months ended September 30, 1998 from $94  in the
three months ended September 30, 1997.  The decrease was related to the
Company's having less cash available to invest in the three months ended
September 30, 1998 compared to the three months ended September 30, 1997 since
the Company has continued to utilize cash during 1998 for acquisitions and other
general corporate needs.

Minority Interest

  Minority interest represents the share of (profits) and losses of minority
investors in certain joint ventures with the Company.  In the three months ended
September 30, 1998, the minority interest in net profits of subsidiaries was
($93)  compared to the minority interest in net losses of subsidiaries equaling
$52 in the three months ended September 30, 1997.  For the third quarter of
1998, the financial performance of the joint venture centers continued to
improve compared to the same period in the prior year.

Gain on Disposition of Investment

  For the three months ended September 30, 1997, the gain on disposition of
investment related to the restructuring of one of the Company's joint ventures.
In connection with such restructuring, the ownership of the joint venture
changed whereby the Company assumed an additional 24% ownership interest in the
joint venture.  Through this transaction, each party in the joint venture
forgave outstanding indebtedness. Additionally, certain assets associated with
one of the joint venture sites were purchased by one of the Company's partners
in consideration for the forgiveness of the Company's note payable to its
partner of approximately $536 and for cash of approximately $56.  This
restructuring resulted in the gain on disposition of investment of $217 to the
Company for the three month period ended September 30, 1997. No such similar
event occurred during the three month period ended September 30, 1998.

NINE MONTHS ENDED SEPTEMBER 30, 1998 AND 1997
---------------------------------------------

Revenue

  Revenue increased 29% to approximately $16,716  in the nine months ended
September 30, 1998 from approximately $12,968 in the nine months ended September
30, 1997.  Of the approximately $3,748 increase in revenue in the nine months
ended September 30, 1998 compared to the nine months ended September 30, 1997,
approximately $2,679 was attributable to the incremental increase of revenue of
centers that were acquired or became part of  a joint venture during the nine
months ended September 30, 1997, $2,697 related to centers acquired subsequent
to September 30, 1997 and the remaining $336  related to additional volume at
existing centers.  These amounts were offset by $1,964  of revenue which related
primarily to the Company's share of a partnership in which the Company sold its
interest on December 31, 1997.

Operating, General and Administrative Expenses

  Operating expenses increased 17%  to approximately  $14,179 in the nine months
ended September 30, 1998 from approximately $12,159 in the nine months ended
September 30, 1997.  This increase was principally due to the acquisition and
development of additional centers.  As a percentage of  revenue, operating
expenses declined to 85% in the nine months ended September 30, 1998 as compared
to 94% in the nine months ended September 30, 1997.  The centers, in the
aggregate, improved their profitability during the nine months ended 
September 30, 1998 compared to the nine months ended September 30, 1997 as
individual centers began to reach critical mass in terms of volume.

<PAGE>
 
  General and administrative expenses increased 11% to approximately  $2,103  in
the nine months ended September 30, 1998 from $1,897 in the nine months ended
September 30, 1997.  The increase was the result of the Company's expanding its
corporate staff to support the growth in the centers and to support additional
business lines.  As a percentage of revenue, general and administrative expenses
decreased to 12% in the nine months ended September 30, 1998 as compared to 15%
in the nine months ended September 30, 1997.  The Company believes that as
additional acquisitions are completed, leveraging of existing management will
occur.

Depreciation and Amortization

  Depreciation and amortization expense increased 10%  to approximately $552  in
the nine months ended September 30, 1998 from approximately $500 in the nine
months ended September 30, 1997.  The increase occurred primarily as a result of
the Company's having additional growth through center development and
acquisitions.  As a percentage of revenue, depreciation and amortization was 3%
in the nine months ended September 30, 1998 compared to 4% in the nine months
ended September 30, 1997.

Interest Income

  Interest income is generated primarily from cash invested in highly liquid
funds with a maturity  of three months or less.  Interest income decreased 46%
to approximately  $143 in the nine months ended September 30, 1998 from $266  in
the nine months ended September 30, 1997.  The decrease was related to the
Company's having less cash available to invest in the nine months ended
September 30, 1998 compared to the nine months ended September 30, 1997 since
the Company  has continued to utilize cash during  1998 for acquisitions and
other general corporate needs.

Minority Interest

  Minority interest represents the share of (profits) and losses of minority
investors in certain joint ventures with the Company.  In the nine months ended
September 30, 1998, the minority interest in net profits of subsidiaries was
($271)  compared to the minority interest in net losses of subsidiaries equaling
$194  in the nine months ended September 30, 1997.  For the first nine months of
1998, the financial performance of the joint venture centers continued to
improve compared to the same period in the prior year.

Gain on Disposition of Investment

  For the nine months ended September 30, 1997, the gain on disposition of
investment related to the restructuring of one of the Company's joint ventures.
In connection with such restructuring, the ownership of the joint venture
changed whereby the Company assumed an additional 24% ownership interest in the
joint venture.  Through this transaction, each party in the joint venture
forgave outstanding indebtedness. Additionally, certain assets associated with
one of the joint venture sites were purchased by one of the Company's partners
in consideration for the forgiveness of the Company's note payable to its
partner of approximately $536 and for cash of approximately $56.  This
restructuring resulted in the gain on disposition of investment of $217 to the
Company for the nine month period ended September 30, 1997. No such similar
event occurred during the nine month period ended September 30, 1998.

Seasonality

  The Company is subject to the natural seasonal swing that impacts the various
employers and employees it serves.  Although the Company hopes that as it
continues its growth and development efforts it may be able to anticipate the
effect of these swings and provide services aimed to ameliorate this impact,
there can be no assurance that it can completely alleviate the effects of
seasonality.  Historically, the Company has noticed these impacts  in portions
of the first and fourth quarters.  Traditionally, revenues are lower during
these periods since patient visits decrease due to the occurrence of plant
closings, vacations, holidays, a reduction in new employee hirings and the
impact of severe weather conditions in the Northeast. These activities also
cause a decrease in drug and alcohol testings, medical monitoring services and
pre-hire examinations.  The Company has also noticed similar impacts during the
summer months, but typically to a lesser degree than during the first and fourth
quarters.
 
LIQUIDITY AND CAPITAL RESOURCES

  Since inception, the Company's funding requirements have been met through a
combination of issuances of capital stock, long-term debt and other commitments,
the utilization of capital leases and loans to finance equipment purchases, the
sale of certain accounts receivable and the creation of minority interests.  Net
proceeds from the sale of capital stock have totaled approximately $14 million,
including the Company's private placement of its Series A Convertible Preferred
Stock on November 6, 1996.  The proceeds from the sale of this preferred stock
provided the Company with cash proceeds of approximately $8.4  million, net of
expenses.  At September 30, 1998, the Company had $4,734  in working capital, a
decrease of $463 from December 31, 1997.  The Company has utilized its funds in
its expansion effort and for working capital.  The Company's principal sources
of liquidity as of September 30, 1998 consisted of (i) cash and cash equivalents
aggregating approximately $2,199 and (ii) current accounts and notes receivable
of approximately $5,377.

  During the quarter, the Company restructured a note receivable arrangement
whereby  a significant portion of the note receivable was prepaid and the
remaining principal  balance of the note was amortized over eight quarters, with
the last payment due on September 30, 2000.  The former arrangement required
quarterly payments  through December 31, 2000, with the last payment being a
sizable balloon payment. The restructured note is unsecured, but bears a higher
interest rate than  the former note.  This arrangement was finalized in October
1998, and the balance sheet reflects the appropriate allocation between short-
term and long-term notes receivable.

  Net cash used by operating activities by the Company during the nine months
ended September 30, 1998 was approximately $597 as compared to approximately
$2,435 for the nine months ended September 30, 1997.  During these periods, the
primary uses of cash were the funding of working capital in centers in early
stages of development or centers that were recently acquired and to fund Company
operating losses. The improvement in net cash used by operating activities is
primarily due to the improved financial performance of the Company's centers.

  The Company's investing activities for the nine months ended September 30,
1998 used cash of  $766 compared to $1,562 for the nine months ended September
30, 1997.  Amounts involved in investing activities included the use of $447 and
$386 for fixed asset additions in the nine  months ended September 30, 1998 and
1997, respectively.  Fixed asset additions for the nine months ended September
30, 1998 related primarily to computer hardware and software. Additional amounts
invested during the nine months ended September 30, 1998 included the purchase
of a physician and physical therapy practice, a 51% interest in a joint venture
and payments related to additional purchase price in accordance with the terms

                                       12
<PAGE>
 
negotiated in connection with certain prior acquisitions. The total payments
amounted to $319.  For the nine months ended September 30, 1997, the Company
paid $1,496 for the purchase of several physician practices and the investments
in two joint ventures.  The Company has an equity interest equal to or in excess
of 51% in all joint ventures. As part of the Company's investment in a joint
venture made during September 1998, the Company acquired $300,000 of accounts
receivable.

  Finally, in the nine months ended September 30, 1998 and 1997, the Company
utilized $672 and $552, respectively, towards the payment of long-term debt and
other long-term obligations.  The Company expects that its principal use of
funds in the near future will be in connection with acquisitions, the formation
of joint venture entities, the establishment of professional service agreements,
working capital requirements, debt repayments and purchases of property and
equipment.  During November  1997, the Company entered into a financing
arrangement with BankBoston, N.A.  whereby it has access to two separate credit
facilities.  The first credit facility provides the Company with $2.5 million
for working capital and acquisition needs.  The second facility provides up to
$4.5 million to be utilized by the Company's existing and future joint ventures.
As of September 30, 1998, the Company's borrowings under the second facility
were approximately $287.  The borrowing base of the joint venture credit
facility is eighty-five percent (85%) of the joint ventures' accounts receivable
less than 120 days old.  Both facilities expire on September 30, 1999.  In
addition, in September 1998, the Company entered into a master lease agreement
whereby it can borrow up to $500,000 related to fixed asset additions
retroactive to January 1, 1998 and through June 30, 1999.  The Company expects
that the cash received as the result of the Merger, the sale of 1,416,667 shares
of its Series A Convertible Preferred Stock, the credit facilities, the
availability of its master lease agreements, and cash generated from operations
will be adequate to provide working capital requirements and to fund debt
repayments and to finance any necessary capital expenditures through December
31, 1998.  However, the Company believes that the level of financial resources
available to it is an important competitive factor.  The Company will consider
raising additional capital on an on-going basis as market factors permit and its
needs suggest since additional capital may be necessary to fund acquisitions by
the Company and the working capital needs of the Company.

IMPACT OF YEAR 2000

  The Company is aware of the issues associated with the programming code in
existing computer systems as the year 2000 approaches.  The "Year 2000" problem
is pervasive and complex, as virtually every computer operation will be affected
in the same way by the rollover of the two digit year value to 00. The issue is
whether computer systems will properly recognize date sensitive information when
the year changes to 2000.  Systems that do not properly recognize such
information could generate erroneous data or cause a system to fail.

  The Company is utilizing both internal and external resources to identify,
correct or reprogram, and test its systems for Year 2000 compliance.  It is
currently anticipated that all reprogramming efforts will be completed by March
31, 1999, allowing adequate time for testing.  A preliminary assessment has
indicated that some of the Company's older personal computers and ancillary
software programs may not be Year 2000 compatible.  The Company intends to
either replace or modify these computers and programs as part of its 1998 and
1999 fixed asset budget in conjunction with converting acquired centers to OH+R
systems. The cost of this replacement is not currently expected to be material
as the shelf life of the Company's personal computers is 3 to 5 years, and as a
result historically each year approximately 25% of all personal computers are
replaced or upgraded. All personal computers purchased in 1997 and through
September 30, 1998 are Year 2000 compatible.

  The Company has also identified the following areas which may be impacted by
the Year 2000 problem:  reimbursement from  its payors and medical equipment
readings.  The Company is  obtaining confirmations from  its primary payors,
equipment manufacturers and vendors that plans are being developed or are
already in place to address processing of transactions in the Year 2000.
However, there can be no assurance that the systems of other companies on which
the Company's systems rely also will be converted in a timely fashion or that
any such failure to convert by another company would not have an adverse effect
on the Company's systems.

  Management is in the process of completing its assessment of the Year 2000
compliance costs. However, based on currently available information (excluding
the possible impact of vendor systems which management currently is not in a
position to evaluate) as noted above, and subject to continued investigation of
this issue, management does not believe that these costs will have a material
effect on the Company's earnings at this time; although budget assessment
efforts are still in process.

INFLATION

  The Company does not believe that inflation had a significant impact on its
results of operations during the last three years. Further, inflation is not
expected to adversely affect the Company in the future unless it increases
substantially, and the Company is unable to pass through the increases in its
billings and collections.

IMPORTANT FACTORS REGARDING FORWARD-LOOKING STATEMENTS

  Statements contained in this Quarterly Report on Form 10-Q, including in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," contain forward-looking statements within the meaning of Section
21E of the Securities Exchange Act, which statements are intended to be subject
to the "safe-harbor" provisions of the Private Securities Litigation Reform Act
of 1995.  The forward-looking statements are based on management's current
expectations and are subject to many risks and uncertainties, which could cause
actual results to differ materially from such statements.  Such statements
include statements regarding the Company's objective to develop a comprehensive
regional network of occupational healthcare centers providing integrated
services through multi-disciplinary teams and the Company's efforts to achieve
Year 2000 compliance.  Among the risks and uncertainties that may affect the
Company's actual results  are locating and identifying suitable acquisition
candidates, the ability to consummate acquisitions on favorable terms, the
success of such acquisitions, if completed, the cost and delays inherent in
managing growth, the ability to attract and retain qualified professionals and
other employees to expand and complement the Company's services, the
availability of sufficient financing and the attractiveness of the Company's
capital stock to finance acquisitions and working capital needs, strategies
pursued by competitors, the restrictions imposed by government regulation,
changes in the industry resulting from changes in workers' compensation laws,
regulations and in the healthcare environment generally, internal and/or third-
party delays or failures in achieving Year 2000 compliance, and other risks
described in this Quarterly Report on Form 10-Q and this Company's other filings
with the Securities and Exchange Commission.
