Dear Stockholder:

      You are cordially  invited to attend a Special Meeting of  Stockholders of
Telor  Ophthalmic  Pharmaceuticals,  Inc.  ("Telor"),  which will be held at the
Second Floor Conference  Center,  One Financial  Center,  Boston,  Massachusetts
02111 at 10:00 a.m.,  local time, on Wednesday,  June 5, 1996 (together with all
adjournments and postponements thereof, the "Special Meeting").

      After  consideration of the materials  transmitted  herewith,  you will be
asked to vote at the Special  Meeting or by signing the enclosed  Proxy,  upon a
proposal to approve an  Agreement  and Plan of Merger  dated as of February  22,
1996,  as  amended as of April 30,  1996,  and as of May 10,  1996 (the  "Merger
Agreement"),  by and between Telor and Occupational  Health + Rehabilitation Inc
("OH+R").  Under the Merger  Agreement,  OH+R will be merged with and into Telor
(the  "Merger"),  Telor will be the  surviving  corporation  of the Merger  (the
"Surviving  Corporation")  and the  name of the  Surviving  Corporation  will be
Occupational  Health + Rehabilitation Inc. After the Merger, the business of the
Surviving  Corporation  will be the  business of OH+R as  conducted  immediately
prior to the Merger.

      Under the terms of the Merger  Agreement,  at the time of the Merger  each
share of common stock,  par value $.01 per share,  of OH+R ("OH+R Common Stock")
will be converted into the right to receive  approximately  .1413123 of a share,
subject to adjustment as provided in the Merger Agreement (the "Share Conversion
Fraction") of the common stock,  par value $.001 per share ("Telor  Stock"),  of
Telor, and each share of Series 1 Preferred Stock, par value $.01 per share, and
Series 2 Preferred  Stock,  par value $.01 per share  (together  "OH+R Preferred
Stock"),  of OH+R, and certain other equity securities of OH+R will be converted
into the right to  receive  Telor  Stock  based on the  number of shares of OH+R
Common  Stock  into which such  share of OH+R  Preferred  Stock or other  equity
security  is then  convertible  multiplied  by the  Share  Conversion  Fraction.
Options to purchase  OH+R  Common  Stock  granted to  employees,  directors  and
consultants  of OH+R and warrants to purchase OH+R Common Stock  outstanding  at
the time of the Merger shall entitle the holder upon exercise in accordance with
the terms thereof to acquire Telor Stock pursuant to the provisions of the plan,
if any, and agreements  pursuant to which they were issued. A copy of the Merger
Agreement is annexed to the accompanying Offering Memorandum and Proxy Statement
(the "Offering  Memorandum/Proxy  Statement") as Appendix A and is  incorporated
therein by reference.

Plan (the "1993 Plan") to increase the number of shares for which options may be
granted under the plan by 105,000, from 140,000 to 245,000. The amendment to the
1993 Plan is a condition to consummation of the Merger.

25,000,000 to 10,000,000.

                                 INTRODUCTION

      This Offering Memorandum/Proxy  Statement is being furnished in connection
with the  solicitation  by the Board of  Directors  of Telor of Proxies from its

      At the  Special  Meeting,  the  stockholders  of  Telor  will be  asked to
consider and vote upon the following proposals:

      (1)  a proposal  to adopt the  Agreement  and Plan of Merger,  dated as of
           February 22, 1996, as amended as of April 30, 1996, and as of May 10,
           1996 (the "Merger Agreement") between Telor and OH+R, a copy of which
           is attached to this Offering  Memorandum/Proxy  Statement as Appendix
           A;

      (2)  a proposal to amend  Telor's 1993 Stock Option Plan (the "1993 Plan")
           to increase  the number of shares of Telor Stock as to which  options
           may be granted; and

      (3)  a proposal to amend Telor's Restated Certificate of Incorporation, as
           amended  (Telor's  "Certificate  of  Incorporation")  to decrease the
           number of shares of Telor Stock authorized to be issued thereunder.

Pursuant to the Merger Agreement, OH+R will be merged with and into Telor, Telor
shall continue as the surviving  corporation  under the laws of Delaware and the
separate  corporate  existence  of OH+R shall cease.  The name of the  Surviving
Corporation shall be Occupational  Health + Rehabilitation Inc. The amendment to
the 1993 Plan will  increase  the  number  of  shares of Telor  Stock  available
thereunder by 105,000 from 140,000 to 245,000. The amendment to the 1993 Plan is
a  condition  to the  consummation  of the  Merger.  The  amendment  to  Telor's
Certificate of  Incorporation  will decrease the number of shares of Telor Stock
authorized to be issued thereunder by 15,000,000 from 25,000,000 to 10,000,000.

      This Offering  Memorandum/Proxy  Statement is also being  furnished to the
OH+R  Securityholders as an Offering  Memorandum in connection with the issuance
of shares of Telor Stock pursuant to the Merger Agreement.

                                    SUMMARY

The Companies

      Telor  Ophthalmic  Pharmaceuticals,  Inc. Telor  initially  operated as an
ophthalmic  pharmaceutical company dedicated to the development and marketing of
innovative  pharmaceuticals for use in the treatment of age-related eye diseases
and in ophthalmic surgery.  Following the failure of its lead product candidate,
XARANOTM,  in Phase III trials,  Telor  curtailed  its research and  development
programs and sought a merger  candidate.  It is  continuing  to seek a corporate
partner to undertake the  development of EY-128,  a compound it studied in Phase
I/II trials for the  reduction of surgical  miosis,  a problem  associated  with
cataract  surgery.  Telor does not  contemplate  that it will undertake  further
development of EY-128 itself.

      Telor  anticipates that if the Merger with OH+R is concluded,  its ongoing
operations will consist of the business of OH+R.

      Telor maintains its principal  executive  offices at 790 Turnpike  Street,
Suite 202, North Andover, Massachusetts 01845, telephone number (508) 681-1062.

      Occupational Health + Rehabilitation Inc OH+R develops,  owns and operates
multidisciplinary,  outpatient healthcare centers for the prevention,  treatment
and management of work-related  injuries and illnesses.  OH+R currently operates
nine centers in the Northeast.  OH+R's centers provide high quality patient care
and a high level of service,  which combined reduce workers'  compensation costs
for employers.  OH+R's approach is to offer a full array of services designed to
reduce  the  frequency   and  severity  of   work-related   injuries,   such  as
pre-placement  examinations,  drug testing and work-site safety programs. OH+R's
treatment  approach is based on documented  proprietary  clinical  protocols and
integrates  state-of-the-art  medical,  rehabilitation,  psychological  and case
management services in a "one-stop shop" focused on solving the problems of both
employers and employees.

      OH+R was  incorporated  in Delaware in 1992.  OH+R maintains its principal
executive offices at 175 Derby Street,  Suite 36, Hingham,  Massachusetts 02043,
telephone number (617) 741-5175.

Special Meeting of Stockholders

      Date, Time and Place. The Special Meeting will be held at the Second Floor
Conference Center, One Financial Center,  Boston,  Massachusetts  02111 at 10:00
a.m., local time, on Wednesday, June 5, 1996.

      Purposes.  At the Special  Meeting  holders of the  outstanding  shares of
Telor  Stock will  consider  and vote upon (1) a proposal  to approve the Merger
Agreement and the Merger,  (2) a proposal to amend the 1993 Plan to increase the

of  Incorporation  to decrease the number of shares of Telor Stock authorized to

      Record  Date.  Telor has fixed the close of business on May 3, 1996 as the
Record Date for  determining  stockholders  entitled to notice of and to vote at
the Special  Meeting.  At the close of business on the Record  Date,  there were
outstanding  and  entitled to vote 786,192  shares of Telor Stock.  See "TELOR'S
SPECIAL MEETING."

      Votes   Required.   Under   Delaware  law  and  Telor's   Certificate   of
Incorporation and Restated By-laws, (1) approval of the Merger Agreement and the
Merger requires the affirmative vote of holders of a majority of the outstanding
shares of Telor Stock entitled to vote at the Special  Meeting;  (2) approval of
the  amendment to the 1993 Plan  requires the  affirmative  vote of holders of a
majority  of the  shares  present or  represented  and  entitled  to vote at the
Special  Meeting;  and (3) approval of the amendment to Telor's  Certificate  of
Incorporation requires the affirmative vote of holders of 70% of the outstanding
shares of Telor Stock entitled to vote at the Special Meeting.

      Telor has obtained the written  agreement of those  holders of Telor Stock
that have an affiliated  person on the Board of Directors of Telor to vote their
shares in favor of the Merger at the Special Meeting. As of April 15, 1996, such
holders  owned an  aggregate  of  298,437  shares of Telor  Stock  (representing
approximately 38% of the outstanding shares of Telor Stock),  and, together with
the  executive  officers and  directors of Telor,  owned an aggregate of 301,877
shares  of Telor  Stock  (representing  approximately  38.4% of the  outstanding
shares of Telor Stock). See "THE MERGER AND RELATED TRANSACTIONS - Merger Voting
Agreement"  and  "INFORMATION  ABOUT  TELOR -  Security  Ownership  and  Certain
Beneficial Owners and Management of Telor."

      Consummation of the Merger is subject to a number of conditions, including
the condition  that no holders of the  outstanding  shares of OH+R capital stock
shall have properly  exercised  their right of appraisal under Delaware law. See
"THE  MERGER  AND  RELATED  TRANSACTIONS  -  Certain  Provisions  of the  Merger
Agreement - Conditions to the Merger."

The Merger

      Recommendation of the Board of Directors;  Telor's Reasons for the Merger.
The Board of Directors of Telor believes that the Merger is in the best interest
of Telor and its  stockholders.  Prior to reaching  its  conclusions,  the Telor
Board of Directors  received a presentation  from, and reviewed the Merger with,
Telor's management and its legal and financial  advisors.  Numerous factors were
taken  into  consideration  by Telor in  entering  into  the  Merger  Agreement,
including,  without limitation that OH+R has an established business in a market
segment  of  the  healthcare  industry  that  is  currently  fragmented,  and an
established operating model that is currently revenue generating; the skills and
experience of OH+R's  management;  the expected  benefits of the availability of
substantial  additional cash and of public company status to OH+R and the belief
that the Merger will allow Telor's  stockholders to participate in the potential
future  growth  of a company  which has  substantially  greater  operations  and
business resources.


                                      13

<PAGE>



      The Telor  Board of  Directors  also  considered  a number of  potentially
negative factors in its deliberation concerning the Merger,  including,  but not
limited to: (i) the risk that the  potential  benefits of the Merger  (including
opportunities  for  expansion of the Surviving  Corporation)  would not be fully
realized; (ii) the risks associated with expansion,  including the need for OH+R
to expand its management team; (iii) the historical  results of OH+R, which have
yielded losses and that losses could be expected to continue for some time; (iv)
the risk that Telor Stock would cease to be listed on the Nasdaq National Market
as a result of the  Merger  with  OH+R;  (v) that  substantially  all of Telor's
pre-Merger  net operating  losses will be  unavailable  to offset future taxable
income;  and (vi) the substantial direct expenses of the Merger. See "THE MERGER
AND RELATED TRANSACTIONS - Telor's Reasons for the Merger."

      OH+R  considered a number of factors in connection  with entering into the
Merger  Agreement.  Primary  among them were the  access to  capital  OH+R would
potentially  gain from  Telor's  cash  balances  and Telor's  status as a public
company,  such access to capital being necessary to fund OH+R's expansion plans.
See "THE MERGER AND RELATED TRANSACTIONS - OH+R's Reasons for the Merger."

      General.  The Merger  Agreement  provides  for the merger of OH+R with and
into  Telor.  Following  the  Merger,  Telor  shall  continue  as the  Surviving
Corporation under the laws of Delaware and the separate  corporate  existence of
OH+R shall cease.  The name of the Surviving  Corporation  shall be Occupational
Health +  Rehabilitation  Inc. Subject to the terms and conditions of the Merger
Agreement,  it is currently  contemplated  that the effective time of the Merger
(the "Effective  Time") will be approximately  June 7, 1996. See "THE MERGER AND
RELATED TRANSACTIONS - Effective Time; Closing Date."

      Conversion  of Shares  of OH+R  Stock  Pursuant  to the  Merger.  Upon the
effectiveness of the Merger,  the outstanding  Equity Securities (as hereinafter
defined)  of OH+R  (other  than (i)  Equity  Securities  of OH+R  held in OH+R's
treasury or by any OH+R  subsidiary and (ii) such Equity  Securities of OH+R, if
any, as may then be owned by Telor)  shall be  cancelled  and  converted  in the
manner set forth below:

            (i) each  outstanding  share of OH+R Common Stock shall be converted
      into and exchanged for the right to receive from the Surviving Corporation
      the Share Conversion Fraction (as hereinafter defined) of a share of Telor
      Stock;

            (ii)  each  outstanding  share  of OH+R  Preferred  Stock  shall  be
      converted  into and  exchanged for the right to receive from the Surviving
      Corporation the number of shares of Telor Stock equal to (x) the number of
      shares of OH+R Common Stock then  receivable upon conversion of such share
      of OH+R Preferred Stock multiplied by (y) the Share  Conversion  Fraction;
      and

            (iii) each option to purchase OH+R Common Stock (the "OH+R  Employee
      Stock  Options") and each warrant to purchase  shares of OH+R Common Stock
      (the "OH+R  Warrants") shall not be converted into and exchanged for Telor
      Stock but shall,

                                      14

<PAGE>



      after the Effective Time,  entitle the holder thereof,  upon exercise,  to
      acquire  Telor  Stock  instead of OH+R  Common  Stock (see "THE MERGER AND
      RELATED TRANSACTIONS - Conversion of Equity Securities of OH+R Pursuant to
      the Merger Conversion of OH+R Employee Stock Options and OH+R Warrants").

      Share  Conversion  Fraction.  The  "Share  Conversion  Fraction"  shall be
calculated on the Closing Date by dividing

            (i)   the sum of

                  (A)   the total number of shares of Telor Stock outstanding as
                        of such date  (approximately  786,192 shares on the date
                        of this Offering Memorandum/Proxy Statement),

                  (B)   the total number of shares of Telor Stock  issuable upon
                        exercise of all  outstanding  options to purchase  Telor
                        Stock (less any options granted to directors who will as
                        of the Effective Time cease to be directors of Telor, to
                        the extent such  options will not be  exercisable  as of
                        the Effective Time or thereafter)  (approximately 34,205
                        shares on the date of this  Offering  Memorandum/  Proxy
                        Statement), and

                  (C)   the  total  number of  shares  of Telor  Stock,  if any,
                        issuable or transferable  upon the conversion,  exchange
                        and/or exercise of any Equity  Securities (other than as
                        provided in clause (B) immediately above),

      by

            (ii)  the sum of

                  (A)   the  total   number  of  shares  of  OH+R  Common  Stock
                        outstanding  as  of  such  date  (approximately  674,605
                        shares  on the  date of this  Offering  Memorandum/Proxy
                        Statement),

                  (B)   the  total   number  of  shares  of  OH+R  Common  Stock
                        receivable   upon  conversion  of  all  shares  of  OH+R
                        Preferred   Stock    outstanding   as   of   such   date
                        (approximately  4,137,843  shares  on the  date  of this
                        Offering Memorandum/Proxy Statement),

                  (C)   the total number of shares of OH+R Common Stock issuable
                        upon  exercise of all OH+R  Employee  Stock  Options and
                        OH+R Warrants outstanding as of such date (approximately
                        993,113   shares   on  the   date   of   this   Offering
                        Memorandum/Proxy Statement), and

                                      15

<PAGE>




                  (D)   the total number of shares of OH+R Common Stock, if any,
                        issuable or transferable  upon the conversion,  exchange
                        and/or exercise of any Equity  Securities (other than as
                        provided in clauses (B) through (D) immediately above.)

      The term "Equity Securities" means, with respect to any person, all shares
of capital stock or other equity or beneficial interests issued by or created in
or by such person,  all stock  appreciation  or similar  rights or grants of, or
their  contractual  obligation  for,  any right to share in the equity,  income,
revenues  or cash  flow of such  person,  and all  securities  or other  rights,
warrants  or other  contractual  obligations  to  acquire  any of the  foregoing
whether by conversion, exchange, exercise or otherwise.

      Based on the  approximate  numbers set forth above,  the Share  Conversion
Fraction  would be .1413123.  The Share  Conversion  Fraction  would increase if
Telor granted more options or issued  additional  Equity  Securities (other than
upon  exercise of currently  outstanding  options)  and would  decrease if Telor
repurchased  shares of Telor Stock or any of its currently  outstanding  options
were  cancelled.  The Share  Conversion  Fraction would decrease if OH+R granted
more options or issued additional Equity Securities (other than upon exercise of
currently  outstanding options) and would increase if OH+R repurchased shares of
its capital stock or any of its currently  outstanding  options or warrants were
cancelled.  Neither  Telor  nor OH+R  expects  to issue  any  additional  Equity
Securities (other than upon the exercise of options) or to repurchase any shares
prior to the consummation of the Merger.  Any grants or cancellations of options
for Telor  Stock or for  capital  stock of OH+R  after  April  15,  1996 are not
expected to be in material amounts.

      Issuance of Additional  Shares of Telor Stock.  The Merger  Agreement also
provides  for the  issuance  of  additional  shares  of Telor  Stock in  certain
circumstances.  In particular, in the event that in connection with that certain
Standard  Form  Industrial  Lease,  dated  July 12,  1994,  by and  between  WRC
Properties,  Inc. (the "Landlord") and Telor (the "Lease") relating to the lease
by  Telor  of  property   located  at  265   Ballardvale   Street,   Wilmington,
Massachusetts  (the  "Premises"),  at any time on or after  January  1, 1997 and
prior to five years after the Commencement Date (as defined in the Lease), which
fifth anniversary is on or about October 31, 1999, the Surviving  Corporation is
required to make any payments to the Landlord or other third  parties on account
of the Lease,  whether such payments are rent or additional  rent payments under
the Lease or as settlement  payments or other costs in  termination of the Lease
or in  connection  with  entering  into a sublease or  subleases,  or to pay any
additional costs in connection with the Premises  including,  without limitation
for heat or other  utilities  and taxes,  then Telor will be  obligated to issue
additional shares of Telor Stock to the OH+R  Securityholders  as of immediately
preceding the Merger in an amount equal to one-half of such payments  divided by
$7.00. In addition,  Telor will be obligated to issue additional shares of Telor
Stock to the OH+R Securityholders if assertions are made during such time period
of liability of Telor under  environmental  laws based on Telor's  operations at
the  Premises,  and if such  liability is finally  determined,  such  additional
shares would be issuable in accordance  with the formula  discussed  above.  See
"THE MERGER AND RELATED TRANSACTIONS -

      Security  Ownership of the Surviving  Corporation.  Upon completion of the
Merger, the Surviving Corporation's officers, directors,  principal stockholders
and their respective  affiliates will own approximately 72.4% of the outstanding
Telor Stock.  Although no voting  agreement or similar  arrangements  among such
stockholders  will exist upon closing of the Merger,  except with respect to the
annual meeting in 1996, if they were to act in concert in the future, they would
be able to elect a majority of the Surviving Corporation's directors,  determine
the  outcome  of most  corporate  actions  requiring  stockholder  approval  and
otherwise  control the business affairs of the Surviving  Corporation.  See "THE
MERGER AND RELATED  TRANSACTIONS  - The  Surviving  Corporation  -  Management,"
"INFORMATION  ABOUT TELOR - Security  Ownership of Certain Beneficial Owners and
Management of Telor" and "INFORMATION ABOUT OH+R - Security Ownership of Certain
Beneficial Owners and Management of OH+R."

      Exchange of  Certificates.  State Street Bank and Trust  Company,  Telor's
transfer  agent,  shall act as exchange  agent (the  "Exchange  Agent"),  in the
administration  of the exchange of certificates  representing  all of the issued
and   outstanding   shares  of  OH+R  Common  Stock  and  OH+R  Preferred  Stock
("Certificates") for certificates  representing shares of Telor Stock,  together
with a check  payable  to such  holder  representing  payment of cash in lieu of
fractional shares as determined in accordance with the Merger Agreement.  If the
Merger becomes  effective,  and if the  capitalization of neither OH+R nor Telor
has changed  within the four  business  days prior to the Closing,  certificates
representing  all of the issued and outstanding  shares of OH+R Common Stock and
OH+R Preferred Stock shall be surrendered for cancellation and termination, and,
simultaneously  with such  cancellation,  a new  certificate for shares of Telor
Stock shall be issued to the holder  thereof,  together  with a check payable to
such  holder  representing  payment  of  cash  in  lieu  of  fractional  shares.
Otherwise,   the  Exchange  Agent  will  mail  a  letter  of  transmittal   with
instructions to each holder of record of OH+R shares as of the Effective Date of
the  Merger  for  use  in  exchanging   their   Certificates   for  certificates
representing  shares of Telor  Stock.  See "THE MERGER AND RELATED  TRANSACTIONS
Certain  Provisions of the Merger  Agreement - Exchange of  Certificates  in the
Merger."

      Conditions to the Merger;  Termination and Amendment.  The consummation of
the Merger is conditioned  upon the fulfillment or waiver of certain  conditions
set forth in the Merger Agreement,  including that the requisite approval of the
stockholders  of Telor and OH+R be obtained  and that no holders of OH+R capital
stock shall have properly exercised their statutory right of appraisal. See "THE
MERGER AND RELATED  TRANSACTIONS - Certain  Provisions of the Merger Agreement -
Conditions to the Merger."

      The Merger Agreement may be terminated by Telor and OH+R with their mutual
consent or by any party  without  the  consent of the other  party if the Merger
does not occur on or prior to June 30, 1996 or if certain  other  events  occur.
The Merger  Agreement  may be  terminated  by Telor if  reasonably  required  by
fiduciary  obligations,  as  determined  in  good  faith  by  Telor's  Board  of
Directors,  subject to the payment of a fee to OH+R. See "THE MERGER AND RELATED
TRANSACTIONS  - Certain  Provisions of the Merger  Agreement  Termination of the
Merger Agreement."

      The Merger Agreement may be amended by mutual written consent of Telor and
OH+R.

      Certain  Federal  Income Tax  Matters.  It is  expected  that,  subject to
certain  assumptions,  the Merger will constitute a tax-free  reorganization for
federal income tax purposes.  See "THE MERGER AND RELATED TRANSACTIONS - Certain
Federal Income Tax Matters."

      Accounting Treatment. It is expected that the Merger will be accounted for
as a "reverse  acquisition"  whereby OH+R will be deemed to have acquired  Telor
for financial  reporting  purposes.  See "THE MERGER AND RELATED  TRANSACTIONS -
Accounting Treatment."

      Governmental and Regulatory Approvals. Consummation of the Merger requires
notifications to certain governmental and other authorities,  which have been or
will be made.  Following the Merger,  Telor Stock will cease to be listed on the
Nasdaq National Market but,

                                      18

<PAGE>



it is expected that it would be listed on the SmallCap  Market.  See "THE MERGER
AND RELATED TRANSACTIONS - Government and Regulatory Approvals."

      Rights of Dissenting Stockholders.  Under Delaware corporate law and based
on the  designation  of the Telor Stock on the Record Date as a Nasdaq  National
Market  security,  holders of record of shares of Telor Stock do not have rights
of dissent or  appraisal  in  connection  with the  approval of the Merger.  See
"TELOR'S SPECIAL MEETING - Rights of Dissenting Stockholders."

      Adams,  Harkness Fairness Opinion.  Adams,  Harkness & Hill, Inc. ("Adams,
Harkness") has rendered a written opinion, dated the date on which this Offering
Memorandum/Proxy  Statement is mailed, to the Board of Directors of Telor to the
effect that the terms of the Merger are fair to the stockholders of Telor from a
financial  point of view.  A copy of such  opinion is  attached as Appendix B to
this  Offering   Memorandum/Proxy   Statement.   See  "THE  MERGER  AND  RELATED
TRANSACTIONS - Adams, Harkness Fairness Opinion."

      Expenses. OH+R and Telor have each agreed to pay its own fees and expenses
(including the fees of any attorneys, accountants,  appraisers or others engaged
by such party) in  connection  with the Merger  Agreement  and the  transactions
contemplated  thereby whether or not the transactions  contemplated  thereby are
consummated.

      Interests of Certain Persons in the Merger. Certain officers and directors
of OH+R will become officers and directors of the Surviving Corporation and will
receive  shares of Telor  Stock in  exchange  for their OH+R  Equity  Securities
and/or their OH+R Equity Securities will become  exercisable for Telor Stock and
one  officer  and  director  will enter into an  employment  agreement  with the
Surviving  Corporation and have an option become  partially  vested  immediately
prior to the Merger.  Mark J. Gabrielson,  a director and Acting Chief Financial
Officer of Telor,  and Angus M. Duthie, a director of OH+R, are General Partners
of Prince  Ventures,  L.P., the General Partner of Prince Venture  Partners III,
L.P.  ("Prince III"). As of April 15, 1996,  Prince III was the beneficial owner
of shares of OH+R Preferred  Stock  convertible  into  2,366,667  shares of OH+R
Common Stock, or 49.2% of OH+R's Common Stock. As of April 15, 1996,  Prince III
was also the  beneficial  owner of 64,936 shares of Telor Stock,  or 8.3% of the
Telor  Stock.  Upon  consummation  of the  Merger,  assuming a Share  Conversion
Fraction  of  .1413123,  Prince III will own  399,375  shares of Telor  Stock or
approximately 27.2% of the capital stock of the Surviving Corporation.  See "THE
MERGER AND RELATED  TRANSACTIONS  -Interests of Certain  Persons in the Merger,"
"INFORMATION  ABOUT TELOR - Security  Ownership of Certain Beneficial Owners and
Management of Telor,"  "INFORMATION  ABOUT OH+R - Security  Ownership of Certain
Beneficial Owners and Management of OH+R" and "CERTAIN RELATIONSHIPS AND RELATED
TRANSACTIONS."

      Standstill Agreement. At the Effective Time, OH+R Securityholders who will
receive  ten  percent or more of the  shares of Telor  Stock to be issued in the
Merger,  all  holders of OH+R  Preferred  Stock,  the holder of the NEB Note (if
converted), all persons who are

                                      19

<PAGE>



directors  and officers of OH+R and Telor and those holders of Telor Stock which
have an affiliated person on Telor's Board of Directors immediately prior to the
Effective Time shall execute and deliver a standstill  agreement  which provides
that they shall not sell,  transfer  or convey any of such shares of Telor Stock
except under limited  circumstances for a period of 180 days after the Effective
Time. See "THE MERGER AND RELATED TRANSACTIONS - Standstill Agreement."

      Merger Voting Agreement. Telor has obtained the written agreement of those
holders of Telor Stock that have an affiliated  person on the Board of Directors
of Telor to vote their shares in favor of the Merger.  Such holders, as of April
15, 1996, owned  approximately 38% of the outstanding shares of Telor Stock. See
"THE MERGER AND RELATED TRANSACTIONS - Merger Voting Agreement."

      Registration  Rights  Agreement.  At the Effective Time,  Telor,  the OH+R
Securityholders  and  holders of Telor  Stock who  currently  have  registration
rights (the "Existing Holders") shall enter into a registration rights agreement
with  respect to the shares of Telor  Stock to be issued or issuable to the OH+R
Securityholders  as a result of the Merger and the shares of Telor Stock held by
the Existing  Holders.  See "THE MERGER AND RELATED  TRANSACTIONS - Registration
Rights Agreement."

      Stockholder  Rights.  The rights of security  holders of Telor will not be
different as a result of the Merger other than as a result of dilution caused by
the issuance of shares of Telor Stock in the Merger.  See  "COMPARISON OF RIGHTS
OF TELOR AND OH+R STOCKHOLDERS."

1993 Plan Amendment; Recommendation of the Board of Directors

      The  Telor  Board of  Directors  unanimously  recommends  approval  of the
amendment  to the 1993 Plan to  increase  the  number of  shares  reserved  from
140,000 to 245,000  for the  following  reasons.  The  increase in the number of
shares  reserved for issuance  under the 1993 Plan is required as a condition to
the  consummation  of the  Merger.  In  addition,  the Board  believes  that the
increase is  advisable  to provide the  Surviving  Corporation  with  sufficient
shares to attract, retain and motivate employees, directors and consultants. See
"PROPOSALS FOR TELOR'S SPECIAL MEETING - Proposal 2: 1993 Plan Amendment."

     Amendment to Telor's  Certificate of  Incorporation;  Recommendation of the
     Board of Directors

      The  Telor  Board of  Directors  unanimously  recommends  approval  of the
amendment  to Telor's  Certificate  of  Incorporation  to reduce the  authorized
number of shares of Telor Stock from  25,000,000 to 10,000,000 for the following
reasons.  The Board  believes  that  10,000,000  shares of Telor Stock will be a
sufficient number of shares whether or not the Merger is consummated.  Moreover,
the amount of Telor's  franchise tax obligation to the State of Delaware will be
reduced substantially by decreasing the number of shares of stock that Telor

                                      20

is authorized to issue. See "PROPOSALS FOR TELOR'S SPECIAL MEETING - Proposal 3:
Amendment to Telor's Certificate of Incorporation."

(1)  Period from inception (July 1, 1992) to December 31, 1992.

(2)  The net loss per share is  computed  by  dividing  net loss,  adjusted  for
     preferred  stock  dividends,  by the weighted  average  number of shares of
     common stock outstanding  during each period presented.  The calculation of
     weighted average shares  outstanding gives effect to the fact that the OH+R
     Preferred Stock does not qualify as a common stock equivalent in any of the
     periods presented.  In addition,  the effect of options and warrants is not
     considered as it would be antidilutive.

      Telor  Stock is traded on the  Nasdaq  National  Market  under the  Nasdaq
symbol  "TELR."  Following  the  Effective  Time, it is expected that the common
stock of the Surviving  Corporation will be traded on the Nasdaq SmallCap Market
under the Nasdaq  symbol  "OHRI".  See "THE  MERGER AND RELATED  TRANSACTIONS  -
Government and Regulatory  Approvals." The following table sets forth,  for each

Telor Stock, all of which have been  retroactively  adjusted for the one-for-ten
reverse stock split of the Telor Stock effective November 15, 1995:

      On December 6, 1995,  the last  trading day prior to the  announcement  by
Telor and OH+R that they had executed a letter of intent  relating to a possible
merger,  the closing sale price of Telor Stock on the Nasdaq National Market was
7 3/4 per  share.  On  February  22,  1996,  the last  trading  day prior to the
announcement  by Telor and OH+R of the  execution of the Merger  Agreement,  the
closing sale price of Telor Stock was 5 1/4 per share. See "- Selected Financial
Information."

      OH+R  Securityholders  are urged to obtain current  market  quotations for
Telor Stock.  No assurance  can be given as to the share value of Telor Stock or
as to the market  price of Telor  Stock at the  Effective  Time of the Merger or
thereafter.

      Telor has not paid cash dividends since inception.  It is anticipated that
the Surviving  Corporation  will retain all earnings for use in the expansion of
the business and therefore does not anticipate  paying any cash dividends in the
foreseeable future. The payment of future dividends will be at the discretion of
the Board of Directors of the Surviving Corporation and will depend, among other
things,  upon  the  Surviving  Corporation's  earnings,   capital  requirements,
financial  condition  and debt  covenants.  As of April  15,  1996,  there  were
approximately 99 record holders of Telor Stock.


                                      25

      There is no public market for OH+R Common Stock.  OH+R has never paid cash
dividends  on its Equity  Securities.  OH+R has  accrued  dividends  on the OH+R
Preferred Stock, the holders of which have agreed to waive the accrued dividends
if the Merger is consummated. As of April 15, 1996, there were eleven holders of
record of the OH+R Common Stock and OH+R Preferred Stock.

Comparative Per Share Data

      The following table sets forth selected historical and pro forma per share
data for Telor and selected  historical  and equivalent pro forma per share data
for OH+R for the fiscal year ended  December 31, 1995.  The equivalent per share
data for OH+R has been computed by multiplying the Telor pro forma amounts by an
assumed Share  Conversion  Fraction of approximately  .1413123.  See "- Selected
Financial Information" and "UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION."
No  assurance  can be given that the  assumed  Share  Conversion  Fraction  will
approximate the actual Share Conversion Fraction.  The Share Conversion Fraction
will not be determined until the Closing.

                                 RISK FACTORS

      This  Offering   Memorandum/Proxy   Statement   contains   forward-looking
statements  within the meaning of Section 27A of the  Securities Act and Section
21E of the  Exchange  Act and are  intended  to be subject to the  "safe-harbor"
provisions of the Private  Securities  Litigation  Reform Act of 1995. Among the
forward-looking  statements is a statement  regarding OH+R's intention to expand
its  business.  The  forward-looking  statements  are  subject to many risks and
uncertainties,  which could cause actual results to differ  materially from such
statements.   In   addition   to  the  other   information   in  this   Offering
Memorandum/Proxy  Statement  including  in  "INFORMATION  ABOUT OH+R - Important
Factors   Regarding   Forward-Looking   Statements,"  the  following  risks  and
uncertainties  should be carefully  considered by holders of Telor Stock and the
OH+R Securityholders.

Risks  of  Future  Acquisitions  and  Management  of  Growth  of  the  Surviving
Corporation; Potential Dilution to Stockholders

      After  the  Merger,  OH+R  intends  to pursue  an  aggressive  acquisition
strategy.  There can be no assurance that suitable acquisition candidates can be
found,  that  acquisitions  can be consummated  on favorable  terms or that such
acquisitions,  if completed, will be successful.  While it is anticipated that a
significant  portion of the capital required to pursue  acquisitions in the next
two years will be provided by the Merger with Telor,  the Surviving  Corporation
may also need to raise  substantial  additional  funds to pursue its acquisition
strategy. There can be no assurance that adequate capital will be available. The
Surviving  Corporation  may  also use  common  stock,  preferred  stock or other
securities of the Surviving Corporation to finance future acquisitions.  The use
of equity  securities to finance future  acquisitions may have a dilutive effect
on the Surviving  Corporation's  stockholders.  In addition, as a result of such
acquisitions, OH+R expects to experience rapid growth in its business and in its
staff, and the Surviving  Corporation's  future results could be affected by its
ability to manage growth  effectively.  See "INFORMATION  ABOUT OH+R - Strategy,
Expansion Plan."

Lack of Profitability

      OH+R's operations have not achieved  profitability,  and the time required
by the  Surviving  Corporation  to achieve  profitability  is  uncertain.  It is
expected that the Surviving  Corporation's  cash  balances,  cash generated from
operations,  available lines of credit and sales of accounts  receivable will be
adequate to satisfy the Surviving  Corporation's cash requirements through 1996.
See "SUMMARY - Selected  Financial  Information" and  "INFORMATION  ABOUT OH+R -
OH+R's  Management's  Discussion and Analysis of Financial Condition and Results
of Operations."

Restrictions Imposed by Government Regulation

      As  a  participant  in  the  healthcare   industry  and  specifically  the
occupational  healthcare  industry,  OH+R's  operations  and  relationships  are
subject  to  extensive,  changing  and  increasing  regulation  by a  number  of
governmental entities at the federal, state and local levels. State and

federal  workers'  compensation  laws control many aspects of providing  medical
services to the individuals covered by such laws (including,  in many cases, the
amounts  that may be charged  for those  services).  State  laws also  generally
prohibit  anyone  other than a licensed  physician  from  engaging  in acts that
constitute  or  contribute  to the practice of medicine and prohibit  physicians
from "splitting"  their fees with other persons.  Federal Medicare laws prohibit
most  referrals  that may  result  in any  financial  benefit  to the  referring
physician  and all  transactions  intended  to  induce  referrals.  OH+R is also
subject to various other federal and state laws. Many of the applicable laws are
enforced by regulatory  authorities  with broad discretion to interpret the laws
and  promulgate  corresponding  regulations,  and  violations  of these laws and
regulations  may  result  in  substantial  penalties.  OH+R  believes  that  its
operations  are  in  material   compliance  with  these  laws  and  regulations.
Nevertheless,  because of the  special  nature of OH+R's  relationship  with the
professional  corporations and satellite clinics that OH+R manages, many aspects
of OH+R's  business  operations  have not been the  subject  of state or federal
regulatory interpretation, and there can be no assurance that a review of OH+R's
or the professional  corporations and satellite  clinics'  business by courts or
regulatory  authorities will not result in a determination that could materially
adversely  affect the operations of OH+R or the  professional  corporations  and
satellite clinics or that the healthcare regulatory  environment will not change
so as to restrict OH+R's or the professional corporations and satellite clinics'
existing  operations or their  expansion.  There can also be no assurance that a
court  or  regulatory   authority   will  not   determine   that  the  Surviving
Corporation's  operations are not in compliance with any other applicable law or
regulation  or that any such  determination  will  not have a  material  adverse
effect on the  Surviving  Corporation.  See  "INFORMATION  ABOUT OH+R - Laws and
Regulations."

Uncertainties Related to Changes in Workers' Compensation Laws or Regulations

      Changes in workers'  compensation laws or regulations may create a greater
or lesser demand for some or all of OH+R's services, require OH+R to develop new
or  modified  services  to  meet  the  needs  of  the  marketplace  and  compete
effectively  or modify  the fees that OH+R may  charge  for its  services.  Many
states are  considering  or have enacted  legislation  reforming  their workers'
compensation  laws. These reforms  generally give employers greater control over
who will provide  medical care to their  employees and where those services will
be provided  and  attempt to contain  medical  costs  associated  with  workers'
compensation  claims.  Some  states  have  implemented   diagnosis-specific  fee
schedules that set maximum  reimbursement  levels for healthcare  services.  The
federal government and certain states provide for a  "reasonableness"  review of
medical costs paid or reimbursed by workers' compensation.  When not governed by
a fee  schedule,  OH+R  adjusts  its charges to the usual and  customary  levels
authorized  by  the  payor.  No  assurance  can  be  given  that  the  Surviving
Corporation  will  prosper  in  the  rapidly  changing  occupational  healthcare
environment. See "INFORMATION ABOUT OH+R - Laws and Regulations."

Competition

      The market to provide healthcare services within the workers' compensation
system is highly fragmented and competitive. OH+R's centers' primary competitors
have typically been

                                      28

<PAGE>



independent  physicians and hospitals.  OH+R anticipates that competition in the
occupational  healthcare industry may shift to specialized  provider groups such
as those managed by OH+R, insurance companies,  health maintenance organizations
("HMOs")  and other  significant  providers  of managed  care  products.  At the
present time,  OH+R is aware of no national  occupational  health  providers and
only a few regional occupational health providers,  including OccuSystems, Inc.,
whose activities are primarily in the South,  Midwest and  Mid-Atlantic  states,
and Atlantic  Health Group, a member of Liberty Mutual Group,  whose  activities
are in the Northeast,  South and Mid-Atlantic states. Many of OH+R's current and
potential  competitors are  significantly  larger and have greater financial and
marketing  resources than OH+R. No assurance can be given that OH+R will prosper
in the changing occupational  healthcare  environment or that OH+R's strategy to
develop  managed care programs will succeed in meeting  employers'  and workers'
occupational  healthcare  needs. See  "INFORMATION  ABOUT OH+R - Expansion Plan,
Competition."

Uncertainties Related to Changing Healthcare Environment

      Numerous healthcare reform proposals have been introduced into Congress in
recent years. Some states have enacted or are considering independent healthcare
reform  initiatives.  It is uncertain what reforms will ultimately be enacted by
the  federal  government  or any state  government.  Significant  changes in the
healthcare  system in the United States may have a substantial  impact over time
on the manner in which OH+R  conducts its  business.  Such changes  could have a
material adverse effect on the Surviving Corporation and on its ability to raise
capital. See "INFORMATION ABOUT OH+R - Laws and Regulations."

Risks Inherent in Provision of Medical Services

      The physicians and other medical  professionals  employed by or affiliated
with OH+R are involved in the delivery of healthcare  services to the public and
therefore are exposed to the risk of professional  liability  claims.  Claims of
this nature,  if successful,  could result in  substantial  damage awards to the
claimants  which may  exceed the limits of any  applicable  insurance  coverage.
Insurance  against  losses  related to claims of this type can be expensive  and
varies widely from state to state.  While OH+R  maintains  liability  insurance,
there can be no assurance  that such  insurance  will be  sufficient  to provide
adequate  coverage for such claims or that such  insurance  will be available in
the  future  at  reasonable  costs  to  the  Surviving  Corporation.  Successful
malpractice   claims   asserted   against  the   physicians  and  other  medical
professionals or OH+R,  however,  could have a material adverse effect on OH+R's
profitability.

Dilution Upon Consummation of the Merger

      Telor stockholders will experience  immediate and substantial  dilution in
book value from $5.84 as of December 31, 1995 to $3.82 on a pro forma basis. See
"SUMMARY  Comparative  Per Share  Data."  Additional  dilution  will  occur upon
exercise of  outstanding  stock options and may occur in connection  with future
financings to meet the Surviving  Corporation's capital  requirements.  See "THE
MERGER AND RELATED TRANSACTIONS - Interests of

                                      29

<PAGE>



Certain Persons in the Merger - Option  Holdings" and  "INFORMATION  ABOUT TELOR
Stock Plans."

Additional Dilution Upon Issuance of Additional Shares to OH+R Securityholders

      The Merger  Agreement  provides  that the  Surviving  Corporation  will be
obligated to issue additional shares of Telor Stock to the OH+R  Securityholders
in the event certain  expenses are incurred in connection  with Telor's lease of
the premises in  Wilmington,  Massachusetts.  Any such issuance would dilute the
interests  of other  holders of Telor Stock at such time.  While Telor  believes
that it will not be required to issue a significant number of shares as a result
of such  provisions,  the number of shares issuable will be dependent on factors
that are uncertain and cannot be  determined  at this time,  including,  without
limitation,  the  ability  of Telor or the  Surviving  Corporation  to  obtain a
replacement  tenant or tenants or subtenants  for the premises  through  October
1999,  whether any such  replacement  tenant or subtenant bears all of the costs
Telor may incur in  connection  with the  premises  during  that time period and
whether any environmental claims are made with respect to the premises. See "THE
MERGER AND  RELATED  TRANSACTIONS  -  Conversion  of Equity  Securities  of OH+R
Pursuant to the Merger - Additional Issuance of Telor Stock."

Dependence Upon Key Personnel

      OH+R is dependent to a substantial  extent upon the continuing efforts and
abilities  of  certain  key  management  personnel.   In  addition,  OH+R  faces
competition for experienced  professionals and other employees with expertise in
the workers' compensation and occupational healthcare areas. The loss of, or the
inability to attract,  qualified  professionals and other employees could have a
material   adverse  effect  on  the  Surviving   Corporation's   business.   See
"INFORMATION ABOUT OH+R - Executive Officer, Key Employees and Directors."

Loss of Listing of Telor Stock on the Nasdaq National Market

      The Telor Stock will not remain listed on the Nasdaq  National Market upon
consummation of the Merger, although it is expected that the Telor Stock will be
listed on the Nasdaq SmallCap  Market.  Among other negative  consequences,  not
being  listed on the Nasdaq  National  Market may reduce the  trading  volume in
Telor  Stock.  See  "THE  MERGER  AND  RELATED  TRANSACTIONS  -  Government  and
Regulatory   Approvals."  In  addition,  in  the  absence  of  the  Merger,  the
substantial reduction in Telor's operations would create a significant risk that
the Telor Stock would cease to be listed on either the Nasdaq National Market or
the Nasdaq SmallCap Market.

Limitation on Carryover of Tax Benefits

      The  Merger  will  result in an  "ownership  change"  of Telor  within the
meaning of section 382 of the Internal Revenue Code. As a result,  substantially
all of  Telor's  pre-Merger  net  operating  losses  and  tax  credits  will  be
unavailable to offset taxable income of the Surviving

                                      30

<PAGE>



Corporation.  See "THE MERGER AND RELATED  TRANSACTIONS - Certain Federal Income
Tax Matters."

Limited Transferability of Telor Stock Issued or Issuable to OH+R
Securityholders

      The shares of Telor  Stock  offered to the OH+R  Securityholders  have not
been  registered  under the Securities Act of 1933, as amended (the  "Securities
Act").  The  Surviving  Corporation  is not  obligated to register  such shares,
except as  described  in "THE MERGER AND  RELATED  TRANSACTIONS  -  Registration
Rights  Agreement."  Rule 144  promulgated  under the  Securities  Act currently
requires,  among other conditions, a two-year holding period prior to the resale
(in limited  amounts) of securities  acquired in a non-public  offering  without
having to satisfy the registration requirements of the Securities Act.

Changes in Market Price of Telor Stock;  Changes in Share  Conversion  Fraction;
Effect of Change of Business on Market

      No  assurance  can be given as to the share  value of Telor Stock or as to
the  market  price  of  Telor  Stock  at the  Effective  Time of the  Merger  or
thereafter. No assurance can be given that the assumed Share Conversion Fraction
will  approximate the actual Share  Conversion  Fraction.  The Share  Conversion
Fraction  will not be determined  until the Closing.  As a result of the Merger,
Telor's business will be changed.  It is not known whether a trading market will
develop in the Telor Stock after the such change. See "SUMMARY - The Merger."

Voting Control of the Surviving Corporation

      Upon  completion  of the Merger,  the  Surviving  Corporation's  officers,
directors,  principal  stockholders  and their  respective  affiliates  will own
approximately 72.4% of the outstanding Telor Stock. Although no voting agreement
or similar  arrangements  among such stockholders will exist upon closing of the
Merger,  except with respect to the annual  meeting in 1996, if they were to act
in  concert  in the  future,  they  would  be able to  elect a  majority  of the
Surviving  Corporation's  directors,  determine  the  outcome of most  corporate
actions  requiring  stockholder  approval  and  otherwise  control the  business
affairs of the Surviving  Corporation.  See "MERGER AND RELATED  TRANSACTIONS  -
Voting  Agreement,"  "INFORMATION  ABOUT TELOR - Security  Ownership  of Certain
Beneficial  Owners and  Management  of  Telor,"  and  "INFORMATION  ABOUT OH+R -
Security Ownership of Certain Beneficial Owners and Management of OH+R."

Board Conflicts of Interest in Recommending the Merger

      Mark J.  Gabrielson,  a director  and Acting  Chief  Financial  Officer of
Telor,  and Angus M. Duthie,  a director of OH+R, are General Partners of Prince
Ventures,  L.P., the General Partner of Prince III. As of April 15, 1996, Prince
III was the beneficial owner of shares of OH+R Preferred Stock  convertible into
2,366,667  shares of OH+R Common Stock,  or 49.2% of OH+R's Common Stock.  As of
April 15, 1996,  Prince III was also the  beneficial  owner of 64,936  shares of
Telor Stock, or 8.3% of Telor Stock. Immediately following the

                                      31

<PAGE>



Merger,  Prince  III will be the  beneficial  owner of  399,375  shares of Telor
Stock, or 27.2%, Mr.  Gabrielson will cease to be a director and Mr. Duthie will
become a director of the  Surviving  Corporation.  The  increase in Prince III's
ownership of Telor Stock will not be sufficient for it to control the outcome of
matters  presented  to  stockholders  for their  approval or the other  business
affairs of the Surviving Corporation,  but will increase Prince III's ability to
influence the outcome of most corporate actions requiring  stockholder approval,
as well as the conduct of the business affairs of the Surviving Corporation. See
"CERTAIN  RELATIONSHIPS  AND  RELATED  TRANSACTIONS,"  "THE  MERGER AND  RELATED
TRANSACTIONS - Interests of Certain Persons in the Merger,"  "INFORMATION  ABOUT
TELOR - Security  Ownership  of Certain  Beneficial  Owners  and  Management  of
Telor," and "INFORMATION  ABOUT OH+R - Security  Ownership of Certain Beneficial
Owners and Management of OH+R."

Dividend Policy

      The  Surviving  Corporation  does not intend to pay cash  dividends on its
common stock in the foreseeable future and anticipates that future earnings will
be retained to finance operations and expansion.

Anti-Takeover  Effects  of  Certain  Charter  and  By-Law  Provisions;  Risks of
Possible Issuance of Preferred Stock

      Telor's   Certificate  of   Incorporation   and  By-Laws  contain  certain
provisions  that could have the effect of making it more  difficult  for a third
party to acquire,  or of  discouraging a third party from attempting to acquire,
control  of the  Surviving  Corporation.  Telor's  Board of  Directors  has been
classified  into three classes,  and directors are elected for three year terms.
Telor stockholders and OH+R  Securityholders  who will hold more than a majority
of the Telor  Stock  after the Merger  have  agreed to vote for the  election of
certain  persons  at  Telor's  annual  meeting  in 1996.  In  addition,  Telor's
Certificate of Incorporation and By-laws contain  provisions which provide that,
among other things,  directors may be removed by the stockholders  only with the
vote of at least 70% of the voting power of the then outstanding shares, special
meetings of the  stockholders  may be called only by the  Chairman of the Board,
the Chief Executive Officer, the President or a majority of the Board, "business
combinations" with "interested  stockholders" may not be consummated without the
vote of holders of at least 70% of all shares of Telor voting stock, and certain
amendments to the Certificate of Incorporation and By-laws,  including,  without
limitation,  to  reduce  the  number  of  authorized  shares  or to  change  the
provisions  described  above  require the approval of holders of at least 70% of
the outstanding  shares of Telor Stock.  In addition,  the Board of Directors of
Telor has the  authority  to issue  shares of  preferred  stock with  rights and
preferences senior to those of the Telor Stock without further vote or action by
the  stockholders of Telor.  Such provisions  could limit the price that certain
investors  might be willing  to pay in the future for shares of common  stock of
the Surviving  Corporation.  These  provisions could also make it more difficult
for

                                      32

<PAGE>



stockholders to change the management of the Surviving  Corporation or to effect
certain  transactions.  See  "THE  MERGER  AND  RELATED  TRANSACTIONS  -  Voting
Agreement," "DESCRIPTION OF CAPITAL STOCK OF TELOR" and "COMPARISON OF RIGHTS OF

                            TELOR'S SPECIAL MEETING

Date, Time and Place of the Special Meeting

      The Special  Meeting will be held at the Second Floor  Conference  Center,
One Financial Center, Boston,  Massachusetts 02111 at 10:00 a.m., local time, on
June 5, 1996.

Record Date and Outstanding Shares

      Only  holders of record of Telor  Stock at the close of business on May 3,
1996 are  entitled  to notice of and to vote at the Special  Meeting.  As of the
Telor Record  Date,  there were 786,192  shares of Telor Stock  outstanding  and
entitled to vote. A majority of the issued and outstanding shares of Telor Stock
will constitute a quorum for the meeting.  Each Telor stockholder is entitled to
one vote for each share held as of the Record Date.

Solicitation of Proxies

      The solicitations of proxies for the Special Meeting are being made by the
Board of  Directors  of Telor.  All  shares of Telor  Stock  represented  at the
Special Meeting by properly executed Proxies received prior to or at the Special
Meeting  will  be  voted  at  such  Special   Meeting  in  accordance  with  the
instructions on such Proxies. If no instructions are indicated,  Proxies will be
voted in favor of the proposal to approve the Merger  Agreement  and the Merger,
in favor of the  proposal to amend the 1993 Plan and in favor of the proposal to
amend  Telor's  Certificate  of  Incorporation.  The Board of Directors of Telor
knows of no other  matters  that  will be  presented  for  consideration  at the
Special Meeting other than the proposals  presented herein. If any other matters
are properly  presented at the Special Meeting for action,  the persons named in
the enclosed form of proxy and acting thereunder will have discretion to vote on
such matters in accordance with their best judgment.

Proxies; Vote Required

      A Telor stockholder who has given a Proxy may revoke it at any time before
it is exercised at a Special  Meeting by delivery to the Secretary of Telor of a
written  notice of  revocation,  by delivering a duly  executed  proxy bearing a
later date or by attending the Special Meeting and voting in person.  Attendance
at the Special Meeting will not, by itself, revoke a Proxy.

      The presence,  in person or by proxy,  of the holders of a majority of the
outstanding  shares of Telor Stock entitled to vote is necessary to constitute a
quorum at Telor's Special Meeting.  Abstentions and broker non-votes are counted
in determining the existence of a quorum.

      At the  Special  Meeting,  the  adoption of the Merger  Agreement  and the
Merger  contemplated  thereby  requires  the  affirmative  vote of  holders of a
majority  of the  outstanding  shares  of Telor  Stock  entitled  to vote at the
Special Meeting. Telor has obtained the written

                                      34

<PAGE>



agreement of those holders of Telor Stock that have an affiliated  person on the
Board of  Directors  of Telor to vote their  shares in favor of  approval of the
Merger at the Special Meeting, which agreement shall be binding unless the Board
of  Directors  of Telor  determines  not to  proceed  with the  Merger  and such
determination  has been made by the Board of Directors based upon the provisions
of the Merger Agreement entitling Telor not to proceed with the Merger. See "THE
MERGER AND RELATED  TRANSACTIONS - Voting Agreement."  Adoption of the amendment
to the 1993 Plan requires the  affirmative  vote of holders of a majority of the
shares of Telor Stock present or represented and entitled to vote at the Special
Meeting.  Adoption of the  amendment  to Telor's  Certificate  of  Incorporation
requires the  affirmative  vote of holders of 70% of the  outstanding  shares of
Telor Stock entitled to vote at the Special Meeting.

      Under Delaware law, with respect to Proposal 1 and Proposal 3, abstentions
and broker non-votes will have the effect of a vote against the proposals.  With
respect to Proposal 2, shares  abstaining,  since they are not affirmative votes
for the  matter,  will have the same effect as votes  against  the matter.  With
respect to Proposal 2, broker non-votes will have no effect on the vote.

      The persons known to the management of Telor to be the  beneficial  owners
of more than 5% of the  outstanding  shares of Telor Stock are set forth herein.
See "INFORMATION  ABOUT TELOR - Security  Ownership of Certain Beneficial Owners
and Management of Telor."

Solicitation Expenses

      Telor  will  bear  the  entire  cost  of   solicitation  of  proxies  from
stockholders and copies of solicitation  material will be furnished to brokerage
houses,  fiduciaries and custodians holding in their names shares of Telor Stock
beneficially  owned by others to forward to such  beneficial  owners.  Telor may
reimburse persons representing beneficial owners of shares for their expenses in
forwarding   solicitation   material  to  such   beneficial   owners.   Original
solicitation of Proxies by mail may be  supplemented  by telephone,  telegram or
personal  solicitation  by  directors,  officers or other  regular  employees of
Telor. No additional  compensation will be paid to directors,  officers or other
regular  employees  for such  services.  All  costs of the  solicitation  of the
proxies will be borne by Telor.  Telor will  reimburse  brokerage  companies and
others for their costs in forwarding proxy materials to beneficial owners.

Rights of Dissenting Stockholders

      Under  Delaware  corporate law and based on the  designation  of the Telor
Stock on the Record Date as a Nasdaq National Market security, holders of record
of  shares  of  Telor  Stock do not have  rights  of  dissent  or  appraisal  in
connection with the approval of the Merger.

                      THE MERGER AND RELATED TRANSACTIONS

      The terms  and  conditions  of the  Merger  are  contained  in the  Merger
Agreement,  a copy  of  which  is  attached  to this  Offering  Memorandum/Proxy
Statement as Appendix A and is incorporated herein by reference. The description
in this Offering  Memorandum/Proxy  Statement of the terms of and  conditions to
the  Merger is  qualified  in its  entirety  by, and made  subject  to, the more
complete information set forth in the Merger Agreement.

General

      The Merger  Agreement,  which was executed and delivered by Telor and OH+R
on February 22, 1996, and amended as of April 30, 1996,  provides that,  subject
to the satisfaction or waiver (where permissible) of certain  conditions,  which
are  described  more  fully  herein,  OH+R will be merged  with and into  Telor.
Following the Merger,  Telor shall continue as the Surviving  Corporation  under
the laws of the  State of  Delaware  and the name of the  Surviving  Corporation
shall be changed pursuant to the Certificate of Merger to Occupational  Health +
Rehabilitation Inc. Upon the effectiveness of the Merger, the outstanding Equity
Securities  of OH+R  (other  than (i) Equity  Securities  of OH+R held in OH+R's
treasury or by any OH+R  subsidiary and (ii) such Equity  Securities of OH+R, if
any, as may then be owned by Telor) shall be  cancelled  and  exchanged  for the
right to receive shares from the Surviving Corporation. See "TERMS OF THE MERGER
- - Conversion of Equity Securities of OH+R Pursuant to the Merger."

Background of the Merger

      In  early  August  1995,  Telor  reported  disappointing  results  from  a
multi-center  based Phase III pivotal study for its principal  compound known as
Xarano.   The  Xarano  results  prompted  Telor  to  re-evaluate  its  strategic
direction, as stated in an announcement on August 30, 1995.

      The Board of Directors  initiated a full  reassessment of Telor's business
strategy.    A   process   for   identifying   and   criteria   for   evaluating
acquisition/merger  candidates  were  adopted by the Telor Board of Directors at
its September 7, 1995 meeting.  It was the intent of the Board to sustain Telor,
or a successor  entity,  as an ongoing  business  concern  capable of  producing
attractive  financial returns to Telor's  stockholders.  Accordingly,  the Telor
Board considered  acquisition of assets or merger with another  operating entity
as an  appropriate  redirection  strategy.  While  Telor has  historically  been
involved in the development of ophthalmic pharmaceuticals, the Board widened the
field of opportunity to other  pharmaceutical  businesses and the  biotechnology
and  healthcare  sectors.  Included  in the  criteria  were  (1) a  need  by the
candidate for the cash Telor could provide,  with the expectation  that the cash
could act as a strategic investment,  (2) the management team, (3) the candidate
would  preferably  be  a  private  company  which  would  be  attracted  to  the
availability of a public securities  market, (4) products for which efficacy had
been  established  or services  which were  currently  being  provided,  (5) the
attractiveness  of the resulting  company to future sources of financing and (6)
current revenues

                                      36

<PAGE>



or an expectation  of revenues in the near-term.  These criteria are referred to
below as the "Initial Criteria."

      As part of the process, Dr. Herdklotz,  Acting Chief Executive Officer for
Telor, had an initial meeting with the Chief Executive Officer of OH+R, Mr. John
Garbarino,  in September of 1995. This meeting  resulted in Mr.  Garbarino being
asked to make a presentation  to the Telor Board at a special meeting on October
10,  1995.  Mr.  Garbarino's  presentation  was  one of four  made by  candidate
companies,  which had been chosen from a list of approximately thirty companies.
The choice was based in part on criteria  established  at the  September 7, 1995
Board meeting.

      As a result of the  presentation on October 10, 1995, OH+R became a strong
candidate to be the vehicle for  redirecting  Telor  activities.  On October 24,
1995,  Dr.  Herdklotz and Telor Board member Mr. Charles  Dimmler,  III, spent a
full day at one of OH+R's  centers  reviewing  OH+R's  business model and future
plans. The information  obtained  further  supported an acquisition of or merger
with OH+R.

      The selection process continued with four presentations by other companies
being made to the Board at an October 26, 1995 special  meeting.  Subsequent  to
this  meeting,  a special  Board meeting was scheduled for November 16, 1995, at
which final selection would be made.

      On November 16th, presentations about the finalists were made to the Telor
Board of Directors.  After extensive  discussion,  it was unanimously decided to
proceed with the acquisition of OH+R by Telor.  Dr.  Herdklotz was instructed to
negotiate a letter of intent with OH+R.

      A special  Board  meeting was held on December 5, 1995,  at which time Dr.
Herdklotz  was given  authority  to execute the letter of intent.  The letter of
intent was signed on  December  6, 1995 and  announced  prior to the  opening of
trading on December 7, 1995. At the December 5, 1995 meeting,  Dr. Herdklotz was
also  authorized  to  proceed  with  his  investigation  and  engagement  of  an
investment banking firm to render an opinion as to fairness of the merger to the
Telor  stockholders from a financial point of view. The firm of Adams,  Harkness
subsequently was engaged to render such opinion.

      The  definitive  Agreement  and Plan of Merger  between Telor and OH+R was
negotiated during the period December 6, 1995 to February 22, 1996, during which
time further due diligence of OH+R was conducted and unaudited results as of and
to December 31, 1995 of both companies were  prepared.  Special  meetings of the
Telor Board were held on January 5, 12, 17 and 29, addressing various aspects of
the agreement,  the related  negotiations  and OH+R's  business.  The definitive
agreement was signed on February 22, 1996 and announced  prior to the opening of
trading on February 23, 1996.

      On April 30, 1996, a Special Meeting of the Telor Board was held, at which
an amendment to the Merger Agreement was approved, providing that the date after
which either

party may terminate the Merger  Agreement upon notice be extended from April 30,
1996 to June 30, 1996 and providing  that the amount of cash,  cash  equivalents
and  short-term  investments  which  Telor  must  have immediately  prior to the
Effective Time be reduced from $5,000,000 to $4,800,000,  net of all liabilities
due and payable and all liabilities for goods delivered and services rendered to
Telor prior to the Effective Time regardless if an invoice  has been rendered to
Telor as of immediately prior to the Effective Time,  excluding (i) all expenses
related  to  the  premises  in  Wilmington,  Massachusetts,  including,  without
limitation,  the subleasing thereof;  (ii) any premium paid or due for directors
and officers liability  insurance;  (iii) the amount, if any, due to Pharmatech,
Inc.; and (iv) fees and  disbursements of counsel to Telor accrued after May 15,
1996.

Telor's Reasons for the Merger

      The Board of  Directors of Telor  believes  that the Merger is in the best
interests  of  Telor's  stockholders  and has  unanimously  approved  the Merger
Agreement  and the  issuance  of the  Telor  Stock  contemplated  thereby  after
consideration of a number of factors.  The Board believes that the following are
reasons  for Telor  stockholders  to vote for  approval  of the  adoption of the
Merger Agreement and the Merger.

      Prior to reaching its conclusions, the Telor Board of Directors received a
presentation  from,  and reviewed the Merger with,  Telor's  management  and its
legal and financial  advisors.  In connection with its review of the Merger, the
Board of Directors reviewed in detail the following additional factors:

     .    OH+R is in the  healthcare  industry,  one of the industries the Telor
          Board of Directors  had announced as being a focus in its search for a
          merger  candidate,  and  was  currently  providing  services  in  that
          industry (criteria 4 of the Initial Criteria);

     .    OH+R has an established business in a market segment that is currently
          fragmented,  and an  established  operating  model  that is  currently
          revenue generating, which business may be attractive to future sources
          of financing (criteria 5 and 6 of the Initial Criteria);

     .    the skills and  experience  of OH+R's  management  (criteria  2 of the
          Initial Criteria);

     .    the  availability of Telor's cash balances to OH+R, which are expected
          to enable it to expand its business  significantly  (criteria 1 of the
          Initial Criteria);

     .    the public  company  status of Telor,  which was  believed  to provide
          access to  financing  alternatives  currently  unavailable  to OH+R, a
          private company (criteria 3 of the Initial Criteria);

     .    the private  company  status of OH+R,  which was  believed to make the
          shares  of  the  Surviving   Corporation  more  attractive  to  OH+R's
          stockholders  and  therefore  to  increase  the value  obtainable  for
          Telor's stockholders;


                                      38

<PAGE>


     .    alternative candidates as merger partners for Telor;

     .    whether  dissolution of Telor,  followed by  distribution of available
          assets  to its  stockholders,  would  yield  lower  value  to  Telor's
          stockholders over time;

     .    the accounting treatment of the Merger;

     .    the likelihood of successful completion of the Merger;

     .    the opinion of Adams,  Harkness  with respect to the fairness to Telor
          and its  stockholders  from a  financial  point of view  (see  "Adams,
          Harkness Fairness Opinion"); and

     .    the Merger  will allow  Telor's  stockholders  to  participate  in the
          potential future growth of a company which has  substantially  greater
          operations and business resources.

      The Telor  Board of  Directors  also  considered  a number of  potentially
negative factors in its deliberation concerning the Merger,  including,  but not
limited to: (i) the risk that the  potential  benefits of the Merger  (including
opportunities  for  expansion)  would  not be fully  realized;  (ii)  the  risks
associated with expansion,  including the need for OH+R to expand its management
team;  (iii) the historical  results of OH+R, which have yielded losses and that
losses could be expected to continue for some time;  (iv) that Telor Stock would
cease to be listed on the Nasdaq  National Market as a result of the Merger with
OH+R; (v) that  substantially  all of Telor's  pre-Merger  net operating  losses
would be unavailable to offset future taxable  income;  and (vi) the substantial
direct expenses of the Merger.

      The  Merger  and the  future  results  of OH+R are  subject  to risks  and
uncertainties, including those set forth in "RISK FACTORS".

      The Telor Board of Directors also  considered,  among other  matters,  (i)
information  concerning OH+R's business,  prospects,  financial  performance and
results,  including  the  financial  statements  as of and for the period ending
December  31,  1995  and  information   regarding  OH+R's  previously   acquired
businesses, as discussed in "INFORMATION ABOUT OH+R"; (ii) current conditions in
OH+R's  industry  and the size of its market,  including  the amount of workers'
compensation  costs in the United  States and the  Northeast,  as  discussed  in
"INFORMATION  ABOUT OH+R - Market Overview," and other providers of occupational
healthcare  services,  as discussed in "INFORMATION ABOUT OH+R - Expansion Plan"
and " - Competition,";  (iii) reports from management as to the results of their
due  diligence  examination;  and (iv) the Board's  belief that the terms of the
Merger Agreement, including the parties' respective representations,  warranties
and  covenants  and  the  conditions  of  their  respective   obligations,   are
reasonable,  including  the  possibility  of  termination  by Telor in the event
Telor's  Board of Directors  determines in good faith that such  termination  is
reasonably  required by  fiduciary  obligations  and the  conditions  to Telor's
obligations  to consummate  the Merger,  as discussed in "THE MERGER AND RELATED
TRANSACTIONS  - Certain

Provisions  of  the  Merger  Agreement  -  Conditions  to  the  Merger"  and  "-
Termination of the Merger Agreement; Termination Fees."

OH+R's Reasons for the Merger

      The Board of  Directors  of OH+R  believes  that the Merger is in the best
interests  of the OH+R  stockholders  and has  unanimously  approved  the Merger
Agreement.   The  Board   believes  that  the  following  are  reasons  for  the
stockholders  of  OH+R  to vote  for  approval  of the  adoption  of the  Merger
Agreement and the Merger.

      The Board of Directors of OH+R believes that adequate capital is essential
to its expansion  plans.  Telor currently has available  capital which could, in
part, support these plans. In addition,  public companies,  such as Telor, often
have better access to capital markets to provide  additional sources of funding,
such  as   funding   for  OH+R's   expansion   plans  and   operational   needs.
Notwithstanding  these  considerations,  there can be no assurance that adequate
capital will be available or that OH+R will  successfully  pursue its  expansion
plans.

Recommendation of the Board of Directors of Telor

      THE BOARD OF DIRECTORS OF TELOR  UNANIMOUSLY  BELIEVES  THAT THE MERGER IS
FAIR TO AND IN THE BEST  INTERESTS OF TELOR AND ITS  STOCKHOLDERS.  THE BOARD OF
DIRECTORS OF TELOR UNANIMOUSLY  RECOMMENDS A VOTE FOR THE ADOPTION OF THE MERGER
AGREEMENT.

Adams, Harkness Fairness Opinion

      The Board of Directors of Telor has retained Adams, Harkness to act as its
financial advisor and to render an opinion as to whether the terms of the Merger
are fair to the Telor  stockholders from a financial point of view.  Pursuant to
an engagement letter dated December 15, 1995, Telor retained Adams,  Harkness to
furnish  financial  advisory and investment  banking  services with respect to a
possible  merger with OH+R.  Such letter provides for a fixed fee, half due upon
engagement and half due upon the Closing of the Merger. Telor has also agreed to
reimburse  Adams,  Harkness  for its  reasonable  out-of-pocket  expenses and to
indemnify it against certain liabilities  relating to or arising out of services
performed  by Adams,  Harkness  as  financial  advisor  to Telor.  The amount of
consideration to be exchanged in the Merger was determined through  negotiations
between Telor management and OH+R and not by Adams, Harkness.

      At a meeting on January 12, 1996, the Telor Board received an oral opinion
from Adams,  Harkness  that was  confirmed in writing as of February 21, 1996 to
the effect  that the  Merger is fair to Telor and  Telor's  stockholders  from a
financial point of view. This oral opinion was subsequently confirmed to Telor's
Chief Executive Officer on or about February 21, 1996, prior to the execution of
the Merger Agreement. Adams, Harkness' opinion is directed only to the financial
terms of the Merger  Agreement and does not constitute a  recommendation  to any
stockholder  of Telor  as to how  such  stockholder  should  vote on any


                                      40

matter presented in this Offering Memorandum/Proxy  Statement. The complete text
of the opinion  (the  "Adams,  Harkness  Fairness  Opinion") is attached to this
Offering Memorandum/Proxy Statement as Appendix B, and the summary of the Adams,
Harkness Fairness Opinion set forth in this Offering Memorandum/Proxy  Statement
is  qualified  in its  entirety by  reference  to the Adams,  Harkness  Fairness
Opinion.  Telor  stockholders  are urged to read such Adams,  Harkness  Fairness
Opinion  carefully  and in its  entirety  for a  description  of the  procedures
followed, factors considered and the assumptions made by Adams, Harkness.

      In reaching its opinion,  Adams, Harkness considered certain financial and
other information,  including, among other things, OH+R's historic and projected
operating results,  OH+R's business and outlook for the foreseeable  future, and
the Merger  Agreement.  In giving its opinion,  Adams,  Harkness relied upon and
assumed, without independent verification,  the accuracy and completeness in all
material  respects of all information that was available from public sources and
of all  information  that was  furnished  to it by  Telor  or OH+R or  otherwise
available to it.

      Adams,  Harkness,  as  part  of  its  investment  banking  activities,  is
continually  engaged in the  valuation of  businesses  and their  securities  in
connection with mergers and acquisitions,  negotiated  underwritings,  secondary
distributions  of  listed  and  unlisted  securities,   private  placements  and
valuations  for  estate,  corporate  and  other  purposes.  The  Telor  Board of
Directors  selected Adams,  Harkness  because of its experience and expertise in
performing  valuation and fairness  analyses and its knowledge of the healthcare
industry.

      Adams, Harkness was retained as an independent financial advisor.  Neither
Adams,  Harkness  nor any of its  affiliates  or  representatives  has any other
relationship   with   Telor  or  OH+R  or   either   of  their   affiliates   or
representatives.

      In rendering its opinion,  Adams,  Harkness did not make or seek to obtain
appraisals of OH+R's assets in connection  with its analyses of the valuation of
OH+R or OH+R's  capital stock.  No  limitations  were imposed by the Telor Board
upon Adams,  Harkness with respect to the  investigation  made or the procedures
followed by Adams,  Harkness in rendering its opinion.  OH+R and its  management
cooperated fully with Adams,  Harkness in connection with its investigation.  In
its analyses, Adams, Harkness made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond OH+R's control. Any such estimate is not necessarily indicative
of actual values,  which may be significantly more or less favorable than as set
forth therein.  Estimates of values of companies do not purport to be appraisals
or  necessarily  reflect the prices at which  companies may actually be sold. In
rendering its opinion, Adams, Harkness, with the Telor Board's consent, reviewed
and relied upon,  among other things:  (a) the audited  financial  statements of
OH+R for 1993 and 1994 and the unaudited financial  statements of OH+R for 1995;
(b) the historical  operating  results of OH+R; (c) the business and outlook for
OH+R  including  1996  financial  projections;  (d) the  Merger  Agreement;  (e)
information  furnished to Adams, Harkness during interviews with certain members
of OH+R's management concerning the prospects of OH+R and its existing business;
(f) certain financial data of comparable publicly traded companies  ("Comparable
Companies") and selected data relating to relevant


                                      41


<PAGE>


recent  business  combinations;  and (g) other  information  deemed  relevant by
Adams, Harkness, such as: product literature from OH+R and Comparable Companies;
information  derived from due  diligence  phone calls to the  customers of OH+R;
research reports on Comparable Companies and trade and industry articles.

      Adams,  Harkness  believes that its analyses must be considered as a whole
and  that  selecting  portions  of its  analyses  and  certain  of  the  factors
considered by it, without considering all factors and analyses,  could create an
incomplete  view of the  processes  underlying  its analyses  and  opinion.  The
preparation of a fairness  opinion is a complex  process and is not  necessarily
susceptible to partial analyses or summary description.

      In rendering its opinion to the Telor Board, Adams, Harkness performed and
presented certain financial and comparative analyses, with such other factors as
it deemed relevant, including, among other things:

      (i)  Company  Comparisons.  Adams,  Harkness  summarized  its  comparative
analysis of public companies.  Adams, Harkness compared certain OH+R data to the
data  of  selected  companies  including  American  Oncology  Resources,   Inc.,
Occusystems,  Inc.  and  Physician  Reliance  Network,  Inc.  (collectively  the
"Control Group").

      Adams,  Harkness  compared OH+R to the companies in the Control Group with
respect to (i) certain recent market data (i.e.,  bid price and estimated market
value),  certain operating data for 1990 to 1995,  including the compound annual
growth  rates for that  period,  the last  twelve  months'  operating  revenues,
operating  income,  net income,  calendar  year 1995  earnings per share and the
projected calendar year 1996 and calendar year 1997 earnings per share estimates
as reported  by First Call and I/B/E/S  ("Comparable  Company  Analyses"),  (ii)
company rankings  according to operating  performance data (i.e.,  over the last
twelve months,  operating  margin and net margin;  sales growth between 1993 and
the last twelve months; and return on equity for the last twelve months for each
Control Group company) and (iii) selected  market data (i.e.,  price to earnings
ratios for the calendar  year 1995,  calendar  year 1996 and calendar  year 1997
estimates based on a consensus  estimate  reported by First Call and I/B/E/S and
price to sales  ratios  ("Market  Performance  Ranking")),  using  both a recent
market price and including mean comparisons.  Based on these comparisons  Adams,
Harkness  concluded that (i) with respect to performance data, OH+R performed in
a range consistent with or at a slight discount to the mean of the Control Group
and (ii) with respect to Market Performance  Ranking the assumed market value of
OH+R is at a discount to the companies in the Control Group.  With regard to the
Market  Performance  Ranking,  the compounded annual growth rate ("CAGR") of the
Control  Group ranged from 95.5% to 71.4%.  OH+R's CAGR of 87.7% was well within
this range. The last twelve months ("LTM") operating margin of the Control Group
ranged from 9.6% to 17.9%. OH+R's calendar year ("CY") 1996 LTM operating margin
of 8.7% was  reasonably  close to this range.  The LTM net margin of the Control
Group  ranged  from  6.3% to 11.7%.  OH+R's CY 1996 net  margin of 8.7% was well
within the range of the Control Group.


                                      42


<PAGE>


      With  regard to the Market  Performance  Ranking,  the value of OH + R was
reviewed  using  the  follosing  datapoints:  (1)  OH+R  value  the  day  of the
announcement;  (2) OH+R value one day prior to the announcement;  (3) OH+R value
one week prior to the  announcement;  (4) OH+R  value  four  weeks  prior to the
announcement;  and (5) OH+R cash value.  While the price to CY 1995 earnings per
share  ("EPS") was not  meaningful  because OH+R did not report  earnings for CY
1995,  the  Control  Group  price to CY 1996 EPS ranged  from 31.1x to 47.6x and
OH+R's price to CY 1996 EPS multiple for all the above datapoints was well below
the Control  Group.  The Control Group price to CY 1997 EPS ranged from 23.1x to
29.1x and  OH+R's CY 1997 EPS  multiple  for all  datapoints  was well below the
range of the Control  Group.  In terms of the Control  Group price to LTM sales,
the  range  was  from  2.6x to 14.0x  and  OH+R's  LTM  sales  multiple  for all
datapoints were well below the range of the Control Group.

      Adams,  Harkness  regarded  the  conclusions  with respect to such data as
neutral to and  consistent  with its opinion with respect to the fairness of the
Merger to Telor and the Telor stockholders.

      (ii) Merger and Acquisition  Comparisons.  Adams,  Harkness summarized its
tabulations,   based  on  selected  merger  and  acquisition  data  provided  by
Securities Data Company,  including  IntegraCare  Inc. and Rehability Corp. (the
"M&A Control  Group").  Adams,  Harkness  compared the Merger to the M&A Control
Group with respect to multiples of the transaction price compared to the revenue
for the  last  twelve  months,  transaction  price  to the  last  twelve  months
operating  income and multiples of the  transaction  price  compared to the book
value.  The M&A Control Group price to LTM sales was 0.7x. The M&A Control Group
price to LTM net income  ranged  from  13.2x to 44.6x.  OH+R was well below this
range.

      For the services of Adams,  Harkness in connection with the Merger, Adams,
Harkness  will be paid  $50,000,  $25,000 of which was paid upon  signing of the
engagement  letter  and  $25,000 of which is payable  upon  consummation  of the
Merger.

otherwise  control  the  business  affairs  of the  Surviving  Corporation.  See

Conversion of Equity Securities of OH+R Pursuant to the Merger

      General. As a result of the Merger, OH+R Securityholders will hold or have
the right to receive upon the exercise or conversion of Equity  Securities fifty
percent (50%) of the outstanding  shares of Telor Stock on a fully diluted basis
as of the  Effective  Time,  as more  fully  described  below.  It is  currently
estimated  that 786,192  shares of Telor Stock will be  outstanding  immediately
prior to the  Effective  Time and that  there  will be  outstanding  options  to
purchase 47,600 shares of Telor Stock. Upon the effectiveness of the Merger, the
outstanding  Equity Securities of OH+R (other than (i) Equity Securities of OH+R
held  in  OH+R's  treasury  or by any  OH+R  subsidiary  and  (ii)  such  Equity
Securities  of OH+R,  if any, as may then be owned by Telor)  shall be cancelled
and converted in the manner set forth below:

            (i) each  outstanding  share of OH+R Common Stock shall be converted
      into and exchanged for the right to receive from the Surviving Corporation
      the Share Conversion Fraction of a share of Telor Stock;

            (ii)  each  outstanding  share  of OH+R  Preferred  Stock  shall  be
      converted  into and  exchanged for the right to receive from the Surviving
      Corporation the number of shares of Telor Stock equal to (x) the number of
      shares of OH+R Common Stock then  receivable upon conversion of such share
      of OH+R Preferred Stock multiplied by (y) the Share  Conversion  Fraction;
      and

            (iii) the OH+R Employee  Stock  Options and the OH+R Warrants  shall
      not be converted  into and  exchanged for Telor Stock but shall be treated
      as provided below.

      Share  Conversion  Fraction.  The  "Share  Conversion  Fraction"  shall be
calculated  on the date of the  Closing as  provided  on pages 15 and 16 of this
Offering Memorandum/Proxy Statement.

      Conversion  of OH+R  Employee  Stock  Options  and OH+R  Warrants.  At the
Effective  Time and  thereafter,  each OH+R Employee  Stock Option and each OH+R
Warrant shall entitle the holder  thereof,  upon exercise in accordance with the
terms  thereof,  to acquire  (instead  of OH+R Common  Stock)  Telor Stock in an
amount  equal to the  number of  shares  of Telor  Stock  that  would  have been
distributable  pursuant  to the Merger at the  Effective  Time in respect of the
number  of shares of OH+R  Common  Stock  issuable  upon  exercise  of such OH+R
Employee Stock Option or OH+R Warrant  (assuming  that any vesting  requirements
had been  satisfied  prior to exercise) at an exercise  price per share of Telor
Stock equal to the number  obtained by  multiplying  (x) the exercise  price per
share of OH+R  Common  Stock  under the terms of such option or warrant by (y) a
fraction,  the  numerator  of which is the number of shares of OH+R Common Stock
issuable  upon  exercise  of such OH+R  Employee  Stock  Option or OH+R  Warrant
immediately  prior  to  the  Merger  (assuming  that  any  vesting  requirements
applicable  thereto had been satisfied prior to exercise) and the denominator of
which is the number of shares of Telor  Stock  issuable  upon  exercise  of such
option or  warrant,  subject in any event to the other terms and  conditions  of
such  OH+R  Employee  Stock  Option  or OH+R  Warrant,  as the case may be.  Any
fractional shares of Telor Stock to which the holder of any OH+R

                                      46

<PAGE>



Employee  Stock Option or OH+R Warrant would be entitled  upon exercise  thereof
shall be treated as provided in the applicable OH+R stock plan and OH+R Employee
Stock Option agreement or OH+R Warrant, as the case may be.

      Fractional  Shares.  No fractional  shares of Telor Stock shall be issued,
but in lieu thereof, each OH+R Securityholder who would otherwise be entitled to
receive a fraction of a share of Telor Stock shall  receive  from the  Surviving
Corporation  an amount of cash  (rounded to the  nearest  cent) equal to the per
share  market value of Telor Stock (based on the last sales price of Telor Stock
as reported on the Nasdaq  National  Market on the most recent trading day prior
to the date of the Closing) multiplied by the fraction of a share of Telor Stock
to which such holder would otherwise be entitled. The fractional share interests
of each OH+R  Securityholder  in each case shall be  aggregated  so that no OH+R
Securityholder  shall receive cash in an amount equal to or greater than the per
share market value of one full share of Telor Stock.

      Additional  Issuance of Telor Stock. In the event that there are Aggregate
Lease  Payments (as defined  below) at any time on or after  January 1, 1997 and
prior to five years after the Commencement  Date (as defined in the Lease) which
fifth  anniversary  is  on  or  about  October  31,  1999,  then  the  Surviving
Corporation  is required  to issue to the OH+R  Securityholders  (including  the
holder  of the NEB  Note  only if the NEB  Note  is  converted  in the  Merger),
additional shares of Telor Stock in accordance with the formula set forth below.
As  used  herein,  "Aggregate  Lease  Payments"  shall  mean  the sum of (i) any
payments by the Surviving  Corporation  to the Landlord on account of the Lease,
whether such payments are rent or additional rent payments under the Lease or as
settlement  payments in termination of the Lease or in connection  with entering
into a sublease or subleases,  including, without limitation, as a result of any
draw by the  Landlord  on those  certain  letters  of  credit  securing  Telor's
obligations  under the Lease,  (ii) any  additional  costs paid by the Surviving
Corporation in connection with the Premises  including,  without  limitation for
heat or other  utilities and taxes but not including any costs  associated  with
violations or alleged violations of environmental laws, (iii) any payment by the
Surviving Corporation to any leasing agent in connection with the termination of
such Lease or the leasing of the Premises to a subtenant or subtenants  and (iv)
at such time as such payments are due to the Surviving  Corporation,  any amount
due to the Surviving  Corporation  from a sublessee or subtenant of the Premises
which  has  not  been  paid  less  the sum of (y) any  amounts  received  by the
Surviving  Corporation  from any  sublessee or subtenant of the Premises and (z)
the amount by which the aforesaid  letters of credit have been  decreased  other
than by payment to the Landlord  either  pursuant to the provisions of the Lease
or as a result of a sublessee or  subtenant  providing a  replacement  letter of
credit  to  secure  all or a  portion  of the  obligations  under  the  Lease or
otherwise.

      Within  thirty  (30) days after the end of the first  calendar  quarter in
which  the  Aggregate  Lease  Payments  exceed  zero and  after  the end of each
calendar  quarter  thereafter in which the Aggregate Lease Payments for which no
adjustment  has  been  made  exceed  zero,  there  shall be  issued  to the OH+R
Securityholders  that  number  of  additional  shares  of Telor  Stock,  if any,
determined  by  multiplying  (i) the  Aggregate  Lease  Payments  for  which  no
adjustment has been made by .50 and (ii) dividing the amount obtained thereby by
seven dollars ($7) (which number

                                      47

<PAGE>



seven (7) shall be subject  to  equitable  adjustment  in the event of any stock
split,  stock  dividend,  reverse stock split,  or  combination of the shares of
Telor  Stock).  In addition,  if there is a written  assertion of a violation of
environmental  laws at the  Premises  leased  under  the  Lease,  which  written
assertion  is received  by the  Surviving  Corporation  at any time prior to the
termination  of the Lease,  but in any event no later than five (5) years  after
the Commencement Date (as defined in the Lease),  and such assertion is directly
as a result  of  Telor's  own  operations  (and not  solely  as a result  of its
tenancy), then, at such time as there has been a final,  non-appealable judgment
by a court of competent jurisdiction or a binding settlement agreement among all
parties in interest with respect to such assertion resulting in liability to the
Surviving  Corporation,  the Surviving  Corporation will be required to issue to
the OH+R Securityholders  additional shares of Telor Stock based upon the actual
amount  of costs  incurred  by the  Surviving  Corporation  as a result  of such
judgment  or  settlement  as  reduced  by  any  funds  to  which  the  Surviving
Corporation is entitled in connection  with such liability  (including,  without
limitation,  any insurance proceeds),  and applying the formula described above.
All  shares of Telor  Stock  which  may be  issued  to the OH+R  Securityholders
pursuant to these  provisions  are  hereinafter  referred to as the  "Additional
Shares." After the consummation of the Merger,  the foregoing  provisions may be
waived or amended  with the consent of the  Surviving  Corporation  and the OH+R
Securityholders  which hold (or upon exercise of OH+R Employee Stock Options and
OH+R  Warrants  would hold,  regardless  of whether  such OH+R  Options and OH+R
Warrants  are  currently  exercisable)  a majority  of that  number of shares as
equals the sum of the number of shares of Telor  Stock  issued in the Merger and
the shares of Telor Stock  issuable  upon  exercise of the OH+R  Employee  Stock
Options and OH+R Warrants. See "INFORMATION ABOUT TELOR - Property of Telor."

Certain Provisions of the Merger Agreement

      Exchange of Certificates in the Merger.  At the Closing (provided that the
capitalization  of neither  OH+R nor Telor has changed  within four (4) business
days immediately preceding the date of the Closing),  Certificates  representing
all of the issued and outstanding shares of OH+R Common Stock and OH+R Preferred
Stock shall be surrendered for  cancellation  and termination in the Merger.  At
the  Effective   Time,   each  such   Certificate   shall  be  cancelled,   and,
simultaneously  with such  cancellation,  a new  certificate for shares of Telor
Stock, representing the number of shares of Telor Stock into which the shares of
OH+R  Common  Stock  and  OH+R  Preferred  Stock  formerly  represented  by such
Certificate  shall have been  converted  in the  Merger,  shall be issued to the
holder  thereof,  together  with a check  payable  to such  holder  representing
payment of cash in lieu of fractional  shares  determined in accordance with the
Merger  Agreement.  From and after the Effective  Time, each  Certificate  which
prior to the  Effective  Time  represented  shares of OH+R Common  Stock or OH+R
Preferred  Stock  shall be deemed to  represent  only the right to  receive  the
certificates  representing  shares  of Telor  Stock and cash  payment  under the
Merger Agreement, if applicable, contemplated by the preceding sentence, and the
holder of such  Certificate  shall cease to have any rights with  respect to the
shares  of OH+R  Common  Stock and OH+R  Preferred  Stock  formerly  represented
thereby.


                                      48

<PAGE>



      If the  capitalization  of either  OH+R or Telor  changes  within four (4)
business  days  preceding  the  Closing,  as promptly as  practicable  after the
Effective  Time (but in no event  later than ten (10) days  after the  Effective
Time of the Merger),  through such  reasonable  procedures as Telor shall adopt,
Telor shall make  available  for  exchange,  the shares of Telor Stock  issuable
pursuant to the  conversion  of shares.  As promptly  as  practicable  after the
Effective  Time (but in no event  later than ten (10) days  after the  Effective
Time),  the  Exchange  Agent  shall mail or deliver to each  holder of record of
Certificates  (i) a  letter  of  transmittal  and (ii)  instructions  for use in
effecting  the  surrender  of the  Certificates  in exchange  for a  certificate
representing  Telor Stock.  Upon surrender of a Certificate for  cancellation to
the  Exchange  Agent or to such  other  agent or agents as may be  appointed  by
Telor, together with such letter of transmittal, duly executed, such agent shall
promptly  deliver (i) a  certificate  for the number of shares of Telor Stock to
which such holder is entitled and (ii) a check in the amount due such holder for
the value computed for any fractional share interest the holder may have.

      Any Certificate  surrendered shall forthwith be cancelled. In the event of
a transfer of ownership of shares of OH+R Common Stock and OH+R Preferred  Stock
which is not registered on the transfer records of OH+R, the appropriate  number
of shares of Telor Stock may be  delivered to a  transferee  if the  Certificate
representing  such shares of OH+R Stock is presented  to the Exchange  Agent and
accompanied  by all documents  required to evidence and effect such transfer and
to evidence  that any  applicable  stock  transfer  taxes have been paid.  Until
surrendered,  each  Certificate  shall,  at any time after the  Effective  Time,
represent  the right to receive upon such  surrender  the  conversion  number of
shares of Telor Stock.  No holder of a Certificate  shall be entitled to receive
any  dividend  or other  distribution  from Telor with  respect to the shares of
Telor Stock such holder is entitled  to receive  upon the  surrender  until such
Certificate is so  surrendered.  Upon such surrender there shall be paid without
interest,  with respect to the number of whole shares of Telor Stock represented
by the certificate or certificates issued upon such surrender: (i) promptly, the
amount of any dividends or other distributions,  if any, that theretofore became
payable and (ii) at the  appropriate  payment  date,  the amount of dividends or
other distributions, if any, with (x) a record date after the Effective Time but
prior to such surrender and (y) a payment date occurring after such surrender.

      After  the  Effective  Time  there  shall be no  further  registration  of
transfers on the stock transfer books of the Surviving Corporation of the shares
of  capital  stock  of OH+R  which  were  outstanding  immediately  prior to the
Effective Time. If Certificates  are presented to the Surviving  Corporation for
any reason, they shall be cancelled and exchanged.

      Telor also has agreed to not,  directly or  indirectly,  solicit any other
party, or, except to the extent reasonably required by fiduciary  obligations or
its duties under the Exchange  Act, as determined in good faith by Telor's Board
of Directors (any such activities  permitted by such exception being referred to
herein as "Permissible  Negotiations"),  reply to any offer (other than to state
that  no  reply  may be  made  at  such  time)  or  enter  into  discussions  or
negotiations  with,  any other  party  regarding  the sale of all or any  Equity

Effective  Time,  OH+R will have no obligations or liabilities  except (a) those
set forth on the  December  31, 1995  consolidated  balance  sheet and (b) those
incurred in the ordinary course of business  consistent with past practice after
the date of the  balance  sheet and prior to the  Effective  Time and  reflected

to use its best  efforts to preserve  its  business  organization  intact and to
preserve its goodwill.  Without  limiting the generality of the foregoing,  OH+R

collected immediately prior to the date of the Merger Agreement. In addition, up
to and including the Effective Time, (i) OH+R has agreed to conduct its business
in a manner such that the representations and warranties contained in the Merger
Agreement  that are qualified as to  materiality  shall  continue to be true and
correct  and  those  that are not so  qualified  shall  continue  to be true and
correct in all material  respects on and as of the Effective  Time as if made on
and as of the Effective Time,  except for changes and the consequences of events
arising  in the  ordinary  and usual  course of  business  consistent  with past
practice  after the date of the Merger  Agreement and none of which would have a
materially  adverse effect on the  properties,  assets,  operations or condition
(financial or otherwise) or prospects of OH+R or any  subsidiary or its business
and except as  otherwise  provided in or  expressly  contemplated  by the Merger
Agreement;  and (ii) OH+R will advise Telor promptly in writing of any condition
or circumstance that could cause any representation or warranty of

                                      52

<PAGE>



OH+R that is qualified as to materiality to become untrue or any  representation
or warranty not so qualified to become untrue in any material respect.

      OH+R has also agreed that none of OH+R, the OH+R Securityholders or any of
their  affiliates,  advisors,  agents or investment  bankers shall,  directly or
indirectly,  enter into discussions or negotiations with any other party,  reply
to any offer  (other  than to state  that no reply may be made at such  time) or
solicit any other party  regarding  the sale of all or any Equity  Securities of
OH+R (with certain limited  exceptions) or the assets or business of OH+R or its
subsidiaries  or any  merger  or  other  capital  reorganization  of OH+R or any
subsidiary.

      Termination  of  the  Merger  Agreement;   Termination  Fees.  The  Merger
Agreement may be  terminated  at any time prior to the Effective  Time by mutual
written  consent duly  authorized  by the Boards of Directors of Telor and OH+R.
The  Merger  Agreement  may be  terminated  by Telor or OH+R if (i) any court of
competent  jurisdiction or other  governmental  body shall have issued an order,
decree or ruling, or taken any other action restraining,  enjoining or otherwise
prohibiting  the  Merger,  provided  that the Merger  Agreement  shall not be so
terminated  unless the party  terminating the Merger  Agreement has utilized its
reasonable  best efforts to oppose the issuance of such order,  decree or ruling
or the taking of such action;  or (ii) the Effective Time has not occurred on or
prior to June 30, 1996 for any reason other than the breach of any  provision of
the Merger Agreement by the party terminating the Merger Agreement; or (iii) the
other party breaches any of its  representations,  warranties or covenants which
are  qualified  as to  materiality  or  breaches  any  of  its  representations,
warranties of covenants which are not so qualified in any material respect,  and
such  breach  is not  cured  within  ten  (10)  days of  written  notice  by the
non-breaching party. The Merger Agreement may be terminated and the transactions
contemplated  thereby  may  be  abandoned  at any  time  prior  to the  Closing,
notwithstanding  approval  of the  Merger  by the  stockholders  of Telor or the
stockholders of OH+R.

      The Merger  Agreement may be terminated at any time prior to the Effective
Time by Telor if (i) any of the  conditions  precedent  to Telor's  obligations,
other  than  any  condition  reasonably  within  Telor's  control,  has not been
satisfied  on or  before  June  30,  1996 or  shall  have  become  incapable  of
fulfillment and shall not have been waived by Telor, for any reason other than a
breach by Telor of any of its  representations,  warranties or agreements in the
Merger  Agreement;  or (ii)  reasonably  required by fiduciary  obligations,  as
determined in good faith by the Board of Directors,  provided that Telor pays to
OH+R in connection with any such termination a fee equal to $300,000.

      In the event the  stockholders  of Telor do not approve the Merger,  Telor
shall pay to OH+R upon demand a fee of $200,000.

      The Merger  Agreement may be terminated at any time prior to the Effective
Time by OH+R if any of the  conditions  precedent to OH+R's  obligations,  other
than  approval  of the  Merger by OH+R  stockholders  and  other  than any other
condition  reasonably within OH+R's control, has not been satisfied on or before
June 30, 1996 or shall have become  incapable of fulfillment  and shall not have
been  waived by OH+R,  for any  reason  other  than a breach by OH+R or any OH+R
Securityholder of any of their representations,  warranties or agreements in the
Merger Agreement.

      Amendment to the Merger Agreement.  The terms and provisions of the Merger
Agreement may be modified or amended only by written agreement executed by Telor
and OH+R.

Registration Rights Agreement

      At the  Effective  Time,  the  Surviving  Corporation  will enter into the
Registration Rights Agreement with the holders of Telor Stock issued pursuant to
the Merger and each  Existing  Holder in the form of Exhibit  6.15 to the Merger
Agreement  attached  hereto as Appendix A,  providing the following  rights with
respect to any shares of Telor  Stock held by them that may not be sold during a
three month period under Rule 144  promulgated  under the Securities Act: (1) up
to two demand registrations, provided that, for each demand, the holders request
registration  for at  least  51%  of  the  registrable  shares;  (2) up to  five
registrations  on Form S-3 (no more  frequently  than once every twelve months),
provided that for each request,  the reasonably  anticipated  aggregate price to
the public of the shares for which the holders request  registration is at least
$500,000,  and (3) incidental  registration  rights on primary  registrations of
shares by the  Surviving  Corporation,  provided in any event that the Surviving
Corporation  shall be permitted to require any such holders to delay any request
for registration or to cease sales under any effective registration statement if
the  Surviving  Corporation  is then  contemplating  a  transaction  that  could
reasonably  be expected to be adversely  affected or the  Surviving  Corporation
would be required to make public  disclosure of  information  the  disclosure of
which at such time could  reasonably  be  expected  to cause a material  adverse
effect upon the Surviving  Corporation's business;  provided,  however, that the
holders  of OH+R  Warrants  shall  have only the  rights set forth in clause (3)
above.  The Surviving  Corporation  will be required to bear  substantially  all
registration  and  selling  expenses  (except  for  underwriting  discounts  and
commissions  relating to the  registrable  shares and the fees of counsel to the
selling  stockholders) in connection with the registration of registrable shares
in such  registrations.  The registration rights will be transferable in limited
circumstances  and may be amended or waived only with the written consent of the
Surviving  Corporation and the holders of at least two-thirds of the registrable
shares then outstanding.

Standstill Agreement

      At the Effective Time, OH+R  Securityholders  who will receive ten percent
or more of the shares of Telor Stock to be issued in the Merger,  all holders of
OH+R Preferred Stock, the holder of the NEB Note (if converted), all persons who
are directors  and officers of OH+R,  all persons who are directors and officers
of Telor and those  holders of Telor  Stock which have an  affiliated  person on
Telor's Board of Directors immediately prior to the Effective Time shall execute
and  deliver  standstill  agreements  which  provide  that they  shall not sell,
transfer  or convey  any of such  shares of Telor  Stock  except  under  limited
circumstances for a period of 180 days after the Effective Time.

Merger Voting Agreement

      Telor has obtained the written  agreement of those  holders of Telor Stock
that have an affiliated  person on the Board of Directors of Telor to vote their
shares  in favor  of  approval  of the  Merger  at the  Special  Meeting,  which
agreement shall be binding unless the Board of Directors of Telor determines not
to proceed with the Merger and such  determination has been made by the Board of
Directors based upon the provisions of the Merger Agreement  entitling Telor not
to  proceed  with the  Merger.  As of April  15,  1996,  such  holders  owned an
aggregate of 298,437 shares of Telor Stock  (representing  approximately  38% of
the outstanding shares of Telor Stock) and, together with the executive officers
and  directors of Telor,  owned an  aggregate  of 301,877  shares of Telor Stock
(representing  approximately  38.4% of the  outstanding  shares of Telor Stock).
OH+R has obtained the written agreement of certain OH+R  Securityholders to vote
their shares in favor of the Merger.

Certain Federal Income Tax Matters

      General.  The following  discussion  summarizes  certain  material federal
income tax  considerations  of the Merger that are  generally  applicable to the
OH+R Securityholders.  This discussion is based on currently existing provisions
of the Code, existing and proposed Treasury  Regulations  thereunder and current
administrative rulings and court decisions,  all of which are subject to change.
Any such  change,  which  may or may not be  retroactive,  could  alter  the tax
consequences to OH+R, Telor or OH+R Securityholders as described herein.

      OH+R  Securityholders  should be aware that this  discussion does not deal
with all federal  income tax  considerations  that may be relevant to particular
OH+R  Securityholders in light of their particular  circumstances,  such as OH+R
Securityholders who are subject to the alternative minimum tax provisions of the
Code or who acquired  their shares in  connection  with stock option plans or in
other compensatory transactions.  In addition, the following discussion does not
address the tax  consequences  of the Merger under  foreign,  state or local tax
laws or the tax consequences of transactions  effectuated  prior to or after the
Merger  (whether or not such  transactions  are in connection  with the Merger).
ACCORDINGLY, OH+R SECURITYHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS
TO THE SPECIFIC  CONSEQUENCES OF THE MERGER,  INCLUDING THE APPLICABLE  FEDERAL,
STATE,  LOCAL  AND  FOREIGN  TAX  CONSEQUENCES  TO THEM OF THE  MERGER  IN THEIR
PARTICULAR CIRCUMSTANCES.

      Neither OH+R nor Telor has  requested a ruling from the  Internal  Revenue
Service (the "IRS") with regard to any of the federal income tax consequences of
the Merger.  The obligation of OH+R to consummate the Merger is conditioned upon
the receipt of an opinion (the "Tax  Opinion") of Mintz,  Levin,  Cohn,  Ferris,
Glovsky and Popeo,  P.C.,  counsel to Telor,  that the Merger will  constitute a
reorganization (a "Reorganization") under Section 368(a) of the Internal Revenue
Code of 1986,  as amended  (the  "Code").  Such Tax Opinion will be based on the
assumption that all documents,  agreements and  representations to be signed and
delivered  in  connection  with the Merger will be duly signed and  delivered in
substantially  the form in which they currently  exist or currently are expected
to exist, that such documents, agreements and

                                      58

<PAGE>



representations are accurate in all material respects, and that the transactions
will proceed as  contemplated  in this Offering  Memorandum/Proxy  Statement and
such documents.  The Tax Opinion is not binding on the IRS and does not preclude
the IRS from adopting a contrary position. The discussion below assumes that the
Merger will qualify as a Reorganization, based upon such Tax Opinion.

      Subject to the limitations and qualifications referred to herein, and as a
result of the Merger's  qualifying as a  Reorganization,  the following  federal
income tax consequences should result:

      (a) No gain or loss will be recognized by the holders of OH+R Common Stock
and OH+R Preferred  Stock upon the receipt of Telor Stock solely in exchange for
such OH+R Common  Stock and OH+R  Preferred  Stock in the Merger,  except to the
extent that a portion of the Additional  Shares is treated as unstated  interest
under the Code.

      (b) The  aggregate  tax  basis  of the  Telor  Stock so  received  by OH+R
stockholders  in the Merger will be the same as the  aggregate  tax basis of the
OH+R Common Stock and OH+R  Preferred  Stock  surrendered  in exchange  therefor
increased by any amount treated as unstated interest on Additional Shares.

      (c) The  holding  period  of the  Telor  Stock so  received  by each  OH+R
stockholder  in the Merger (other than the portion of Additional  Shares treated
as unstated  interest)  will  include the period for which the OH+R Common Stock
and OH+R Preferred Stock  surrendered in exchange  therefor was considered to be
held,  provided  that  the  OH+R  Common  Stock  and  OH+R  Preferred  Stock  so
surrendered is held as a capital asset at the time of the Merger.

      (d) No gain or loss will be  recognized by and there shall be no corporate
income tax liability to OH+R,  Telor or the Surviving  Corporation  by reason of
the Merger (other than  recognition  of interest  expense  corresponding  to the
portion of Additional Shares treated as unstated interest).

      The Tax  Opinion  is  subject  to the terms and  conditions  of the Merger
Agreement and certain  representations  and covenants  received from OH+R, Telor
and  certain  stockholders  of  OH+R,   including   representations  in  certain
certificates delivered to counsel by certain stockholders of OH+R, the truth and
accuracy of which are assumed for  purposes of  rendering  the Tax  Opinion.  In
particular,  certain of these  representations are qualified as to the knowledge
of the relevant party. If the facts as represented are not accurate,  the Merger
may fail to qualify as a Reorganization.

      To satisfy the  "continuity of interest"  requirement,  OH+R  stockholders
must not,  pursuant to a plan or intent  existing  at or prior to the  Effective
Time of the  Merger,  dispose  of or  transfer  so much of either (i) their OH+R
Common Stock or OH+R Preferred  Stock in  anticipation of the Merger or (ii) the
Telor Stock to be received in the Merger (collectively, "Planned Dispositions"),
such that the OH+R stockholders,  as a group, would no longer have a significant
equity   interest  in  the  OH+R  business  being  conducted  by  the  Surviving
Corporation

                                      59

<PAGE>



after the  Merger.  OH+R  stockholders  will  generally  be regarded as having a
significant  equity  interest as long as the Telor Stock  received in the Merger
(after taking into account Planned Dispositions), in the aggregate, represents a
substantial   portion  of  the  entire   consideration   received  by  the  OH+R
stockholders in the Merger.  For advance ruling  purposes,  the IRS considers an
interest equal to 50% or more of the fair market value of the outstanding shares
of OH+R held immediately before the Merger as a significant equity interest (the
"IRS Continuity  Test"). In rendering its opinion,  Mintz,  Levin, Cohn, Ferris,
Glovsky and Popeo, P.C. will rely upon written representations made by each OH+R
stockholder to the effect that the  stockholder has no current plan or intention
to dispose of any shares of the  Surviving  Corporation  received in the Merger.
Based on such  representations,  the IRS  Continuity  Test should be  satisfied.
However,  if a majority  of the  Surviving  Corporation  stock  received by OH+R
stockholders  in the Merger is disposed  of soon after the Merger (for  example,
within two years,  although no definitive  time limit exists) the IRS may assert
that such  dispositions  were in fact a part of the plan of merger  and that the
"continuity  of interest"  requirement  of a  Reorganization  is  therefore  not
satisfied.

      A successful IRS challenge to the Reorganization  status of the Merger (as
a result of a failure of the "continuity of interest"  requirement or otherwise)
would  result  in  significant  tax  consequences.  An  OH+R  stockholder  would
recognize  gain  or loss  with  respect  to each  share  of OH+R  capital  stock
surrendered  equal to the  difference  between the  stockholder's  basis in such
share and the fair market value,  as of the Effective  Time, of the Telor Stock.
In such event, a  stockholder's  aggregate  basis in the Telor Stock so received
would equal its fair market value, and the stockholder's holding period for such
stock would begin the day after the Merger.

      Even if the Merger qualifies as a Reorganization, a recipient of shares of
Telor Stock would  recognize gain to the extent that such shares were considered
to be  received  in exchange  for  services or property  (other than solely OH+R
capital stock). Gain would also have to be recognized to the extent that an OH+R
stockholder  was treated as  receiving  (directly or  indirectly)  consideration
other than Telor Stock.  All or a portion of such gain amounts may be taxable as
ordinary income.

      Limitations on Net Operating  Losses.  At December 31, 1995, Telor had net
operating loss  carryforwards for tax purposes of approximately  $30,344,000 and
tax credit carryforwards of approximately  $735,000.  As a result of the Merger,
an  "ownership  change" of Telor will occur within the meaning of section 382 of
the Code. As a result of such ownership change, substantially all of Telor's net
operating losses and credit  carryforwards  will be unavailable to the Surviving
Corporation.

      Similarly, at December 31, 1995, OH+R had net operating loss carryforwards
for tax purposes of approximately $4,625,000,  the use of which by the Surviving
Corporation will be limited by the operation of section 382 of the Code.

      Fractional  Shares.  An  OH+R  stockholder  receiving  cash  in  lieu of a
fractional  share in the Merger will generally  recognize a capital gain or loss
in the  amount  of the  difference  between  that  cash  received  and the basis
allowable to the corresponding fractional share.

                                      60

<PAGE>




      Conversion  of OH+R  Employee  Stock  Options.  No  gain  or loss  will be
recognized by the holder of an OH+R Employee Stock Option upon the conversion of
such option into an option to acquire  shares of the  Surviving  Corporation  in
connection with the Merger.  Generally, such holder will realize ordinary income
upon  exercise of the option in an amount equal to the excess of the fair market
value of the stock  acquired  upon  exercise  over the exercise  price,  and any
subsequent gain or loss will be capital gain or loss.

      Conversion  of OH+R  Warrants.  Current law is  unsettled  as to whether a
holder  of OH+R  Warrants  will  recognize  gain  upon  conversion  of such OH+R
Warrants  into  warrants  to  acquire  stock  of the  Surviving  Corporation  in
connection  with the Merger.  A recent  Internal  Revenue Service private letter
ruling,  LTR 9539020,  has reportedly held, in the circumstances of that ruling,
that the  conversion  of  noncompensatory  options  pursuant to their terms into
similar options of an acquiring  corporation in a tax-free  reorganization was a
nontaxable part of the  reorganization.  A contrary position is expressed in the
Treasury  Regulations,  ss.  1.354-1(e),  stating  that an  exchange of warrants
pursuant to a reorganization does not qualify for tax-free treatment.  A private
letter  ruling  cannot be cited as authority by a person other than to whom such
letter is addressed,  and holders of OH+R Warrants seeking to treat the exchange
of OH+R Warrants as tax-free are urged to consult their own tax advisors.

      Receipt of Additional Shares. An OH+R Securityholder  receiving Additional
Shares  pursuant to the Merger  Agreement will be treated for federal income tax
purposes as if a portion of the Additional  Shares were interest  reflecting the
fact that such  Additional  Shares are received after a period of time following
the  Merger.  The amount to be treated as interest is the excess of (a) the fair
market value of the Additional  Shares at the time of receipt over (b) such fair
market value discounted back to the date of the Merger at a  statutorily-defined
test rate. The current annual test rate is 5.32% for Additional  Shares received
within three years of the Effective Time,  5.61% for Additional  Shares received
between three and nine years of the  Effective  Time,  and 6.09% for  Additional
Shares received thereafter.

      The amount so treated as interest  will be reportable by the recipient and
deductible by the Surviving  Corporation at the time such Additional  Shares are
paid (or accrued, for an accrual basis taxpayer). The amount treated as interest
will  constitute  an  increase  in the  basis of the  recipient's  corresponding
Additional  Shares,  and the holding period for the portion of Additional Shares
representing interest will begin upon acquisition of such Additional Shares.

Status Under Federal Securities Laws

      The issuance of Telor Stock pursuant to the  transactions  contemplated by
the Merger  Agreement has not been registered  under the Securities Act or state
securities  (blue sky) laws,  and such  securities  may not be resold,  pledged,
hypothecated,   donated   or   otherwise   transferred   (whether   or  not  for
consideration)  by  the  holder  except  upon  the  issuance  to  the  Surviving
Corporation  of a favorable  opinion of its  counsel  and/or  submission  to the
Surviving  Corporation of such other evidence as may be  satisfactory to counsel
to the Surviving  Corporation,  to the effect any such transfer  shall not be in
violation of the Securities Act or any such blue sky laws.

The certificates representing the Telor Stock will bear a legend evidencing such
restrictions. See, however, "- Registration Rights Agreement."

Accounting Treatment

      It is  expected  that  the  Merger  will be  accounted  for as a  "reverse
acquisition"  whereby OH+R will be deemed to have  acquired  Telor for financial
reporting  purposes.  Upon consummation of the Merger,  former OH+R shareholders
will hold in  excess of 50% of the  outstanding  common  stock and  in-the-money
options  of the  Surviving  Corporation.  Consequently,  OH+R will  control  the
Surviving  Corporation  and is deemed to be the  acquirer.  Consistent  with the
reverse acquisition  accounting  treatment,  historical financial statements for
the  Surviving  Corporation  for periods prior to the date of the Merger will be
those of OH+R. Under the purchase method of accounting,  balances and results of
operations  of Telor will be included in the Surviving  Corporation's  financial
statements from the date of the transaction forward.

Government and Regulatory Approvals

      The Telor Stock is currently  listed on the Nasdaq  National  Market.  The
by-laws of the National Association of Securities Dealers, Inc. ("NASD") related
to Nasdaq  listings  provide  that in the event of a merger by a listed  company
that  results in a change of control and either a change in business or a change
in  financial  structure,  the  listed  company  must meet the  initial  listing
criteria  for the listed  security.  Telor has been  informed by Nasdaq that the
Merger  will be treated by Nasdaq as a change of control  and either a change in
business or a change in financial  structure and that the Surviving  Corporation
will not meet the  initial  listing  criteria  for the Nasdaq  National  Market.
Accordingly,  upon consummation of the Merger,  the Telor Stock will cease to be
listed on the Nasdaq National Market.  Nasdaq has informed Telor that its shares
of common stock will be approved for listing on the Nasdaq  SmallCap Market upon
effectiveness  of the Merger  subject to  confirmation  of  compliance  with all
initial inclusion  standards for the Nasdaq SmallCap Market. It is expected that
the Telor Stock will be listed on the Nasdaq SmallCap  Market upon  consummation
of the Merger. In addition, filings will be required to be made with the SEC and
state securities authorities.

Interests of Certain Persons in the Merger

      General.  Certain  officers and directors of OH+R will become officers and
directors of the Surviving  Corporation and will receive Telor Stock in exchange
for their OH+R Common  Stock.  Such  persons may also hold OH+R  Employee  Stock
Options, which, at the Effective Time, will entitle the holders to receive, upon
exercise,  shares of Telor Stock.  See " - Option  Holdings." John C. Garbarino,
Chief  Executive  Officer,  President and a director of OH+R, will enter into an
Employment  Agreement  with  the  Surviving  Corporation.  See  "  -  Employment
Agreement."

      In  considering  the  recommendation  of Telor's  Board of Directors  with
respect to the Merger,  Telor stockholders  should be aware that certain members
of Telor's  management  and its Board of Directors  have interests in the Merger
that are in addition to their  interests as Telor  stockholders.  As a result of
the Merger,  John K. Herdklotz,  Ph.D. will cease to be the Acting President and
Chief Executive Officer and Secretary. See "INFORMATION ABOUT TELOR - Employment
and  Consulting  Agreements,  Termination  of  Employment  and Change of Control
Arrangements." Mark J. Gabrielson, a director and Acting Chief Financial Officer
of Telor,  and Angus M.  Duthie,  a director of OH+R,  are  General  Partners of
Prince Ventures,  L.P., the General Partner of Prince III. As of April 15, 1996,
in addition to 64,936 shares of Telor Stock held by Prince III, or 8.3% of Telor
Stock,  Mr.  Gabrielson was the beneficial  owner of 1,600 shares of Telor Stock
that may be acquired  upon the  exercise of options  within 60 days of April 15,
1996. Mr. Gabrielson disclaims beneficial ownership of the shares of Telor Stock
held by Prince III. Upon the consummation of the Merger, Mark J. Gabrielson will
cease to be a director and Acting Chief Financial  Officer of Telor and Angus M.
Duthie  will  become a director of the  Surviving  Corporation.  As of April 15,
1996,  Prince III was the  beneficial  owner of shares of OH+R  Preferred  Stock
convertible  into  2,366,667  shares of OH+R  Common  Stock,  or 49.2% of OH+R's
Common  Stock.  Upon  consummation  of the Merger,  assuming a Share  Conversion
Fraction  of  .1413123,  Prince III will own  399,375  shares of Telor  Stock or
approximately  27.2% of the  capital  stock of the  Surviving  Corporation.  See
"INFORMATION  ABOUT TELOR - Security  Ownership of Certain Beneficial Owners and
Management of Telor,"  "INFORMATION  ABOUT OH+R - Security  Ownership of Certain
Beneficial Owners and Management of OH+R" and "CERTAIN RELATIONSHIPS AND RELATED
TRANSACTIONS."  Each of the members of Telor's  Board of Directors  was aware of
those  interests in effect on the date of approval of the Merger  Agreement  and
considered them, among other matters,  in approving the Merger Agreement and the
transactions contemplated thereby.

      Employment  Agreement.  At the Effective Time, John C. Garbarino will have
entered into and delivered an Employment  Agreement which provides that he shall
serve as President and Chief Executive Officer of the Surviving  Corporation for
an initial term of two years, with automatic  extensions for additional one year
terms.  Mr.  Garbarino  may  be  terminated  immediately  for  cause  or  may be
terminated  without cause,  in which event he is entitled to severance pay equal
to six months basic  salary.  Mr.  Garbarino  will  receive an annual  salary of
$180,000,  subject to annual review.  The  Employment  Agreement also contains a
provision  prohibiting  Mr.  Garbarino,  for a period  of six  months  after the
termination  of his  employment,  from engaging in activities in  competition or
interference with the Surviving Corporation.

      Option  Holdings.  In  connection  with the Merger,  certain OH+R Employee
Stock  Options and OH+R Warrants  exercisable  for OH+R Common Stock will become
exercisable for Telor Stock and the exercise prices will be adjusted by dividing
the  current  exercise  price by the  Share  Conversion  Fraction.  Based on the
current  estimate of the Share  Conversion  Fraction of  .1413123,  the exercise
prices  would be increased by  multiplying  them by 7.0765248  and the number of
shares reduced by the Share Conversion Fraction. As of the date of this Offering
Memorandum/Proxy  Statement,  there are an aggregate  of 844,963  OH+R  Employee
Stock Options with a weighted  average exercise price of $0.35. The following is
a summary of the OH+R Employee Stock Options  exercisable  for OH+R Common Stock
held as of April 15, 1996 by the current executive  officers,  all key employees
and directors of OH+R:

              UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

                  Telor Ophthalmic Pharmaceuticals, Inc. and
                   Occupational Health + Rehabilitation Inc



      The following  Unaudited Pro Forma  Combined  Balance Sheet as of December
31, 1995 and the Unaudited Pro Forma  Combined  Statement of Operations  for the
year ended  December 31, 1995 give effect to the Merger  accounted for under the
reverse acquisition purchase method of accounting. The financial information for
the year ended  December 31, 1995 for Telor has been obtained from the financial
statements  of Telor  which  have been  audited  by  Arthur  Andersen  LLP.  The
consolidated financial information for the year ended December 31, 1995 for OH+R
has been obtained from the consolidated  financial statements of OH+R which have
been audited by Ernst & Young LLP.

      The Unaudited Pro Forma  Combined  Financial  Information  is based on the
historical  financial  statements  of Telor and OH+R under the  assumptions  and
adjustments  set  forth in the  accompanying  Notes to the  Unaudited  Pro Forma
Combined Financial  Information.  The Unaudited Pro Forma Combined Balance Sheet
assumes that the Merger was  consummated on December 31, 1995, and the Unaudited
Pro  Forma  Combined  Statement  of  Operations  assumes  that  the  Merger  was
consummated on January 1, 1995.

      The Pro Forma adjustments are based on the reverse  acquisition  method of
accounting,  which provides that the net assets of the acquired  company (Telor)
be recorded at their historical cost, which approximates fair value.

      The  Unaudited  Pro  Forma  Combined  Financial   Statements  may  not  be
indicative  of the results that  actually  would have occurred if the Merger had
been in effect on the dates  indicated  or which may be  obtained in the future.
The  Unaudited  Pro  Forma  Combined  Financial  Statements  should  be  read in
conjunction with the historical  financial  statements and accompanying notes of
Telor and OH+R.

C.    Adjustments to Statement of Operations

      The  adjustment  to  weighted  average  common  shares  and  common  share
equivalents  outstanding  for purposes of computing pro forma net loss per share
reflects the conversion of shares of OH+R Common Stock and OH+R Preferred  Stock
into Telor Stock at a conversion ratio of 0.1413123.

D.    Non-Recurring Adjustment Attributable to the Merger

      Upon the  consummation  of the  Merger,  a new  measurement  date  will be
established  for the former  OH+R  options.  In  accordance  with EITF 90-9,  an
analysis will be performed to determine whether a charge to compensation expense
and credit to paid-in  captital will be required  based upon the market value of
the Telor Stock  immediately  after the Merger. An estimate of such compensation
expense cannot be determined at this time. Once determined,  such charge will be
recorded  in the quarter  that the Merger  closes to the extent that the options
are vested.  Compensation  expense related to options which are unvested will be
amortized over the remaining vesting period.

                            INFORMATION ABOUT TELOR

Business of Telor

      Telor was  organized as a Delaware  corporation  in April 1988.  Since its
inception,  it has been engaged in research and  development of products for use
in ophthalmic surgery and age-related diseases of the eye.

      On August 9, 1995,  Telor  announced  results of the analysis of its Phase
III  clinical  trials  of its lead  product  candidate,  XARANO.  Those  results
indicated that the trials did not support continuation of the XARANO development
program. Separately, also on August 9, 1995, Telor announced positive results of
its Phase I/II trial of a compound, EY-128, to reduce surgical miosis, a problem
associated with cataract surgery.

      On August 30,  1995,  Telor  announced a  restructuring  with a work force
reduction  designed  to  substantially  reduce  Telor's  rate  of  cash  use for
operations.  Telor also  announced its  intention to find and evaluate  business
opportunities,  potentially including identifying a merger candidate and seeking
a corporate  partner to support the  clinical  program  for the  development  of
EY-128 for the treatment of surgical miosis.

      As of December 31, 1995, Telor had reduced its work force to one full-time
employee.  Dr. Arthur H. Neufeld,  Executive Vice President and Chief Scientific
Officer,  resigned  his post and as a Director on October 31, 1995 to seek other
opportunities. He has accepted a position at the Washington University School of
Medicine. He continues to serve Telor as a consultant.  Certain former full-time
employees  continue  to  serve  Telor  on  a  part-time  basis.  Telor's  Acting
President,  Chief Executive  Officer and Secretary,  John K.  Herdklotz,  Ph.D.,
continues to provide those services on a consulting basis.

      While  Telor  was  searching  for a merger  candidate,  it  curtailed  its
research and development programs. As of April 15, 1996, Telor was conducting no
research  and  development  activities,   had  sold  substantially  all  of  its
laboratory equipment and terminated all of its scientific consulting agreements.
It is continuing to search for a corporate partner to further the development of
EY-128 for the treatment of surgical miosis.

      Telor anticipates that if the merger with OH+R is concluded, the Surviving
Corporation  will  continue  to  seek  a  corporate  partner  to  undertake  the
development of EY-128.  It does not expect to continue  research and development
of any of its other compounds either directly or by actively seeking a licensee.

Property of Telor

      In mid November  1995,  Telor moved its principal  offices to 790 Turnpike
Street, Suite 202, North Andover, Massachusetts. It has been actively seeking to
obtain a sublessee or sublessees for its leased facility of approximately 50,000
square feet at 265 Ballardvale Street, Wilmington, Massachusetts or to terminate
the lease by securing a replacement lessee or lessees.

                                      71

<PAGE>



There is a signed nonbinding  letter of intent with one potential  sublessee for
approximately  half of the  space  and a verbal  understanding  of  intent  with
another  potential  sublessee  for  the  other  half  of the  space.  Under  the
preliminary  terms now under  negotiation,  Telor currently  anticipates  that a
lease with one sublessee  will be signed on or about the date hereof, subject to
obtaining written consent to the sublease from the landlord,  with rent payments
commencing 60 days after the date such consent is obtained.  With respect to the
second potential sublessee,  negotiations are proceeding,  but no estimated date
of signing can be made. Further, Telor cannot predict if and when either of such
leases will be concluded or that the negotiations will result in favorable terms
for Telor.

Legal Proceedings of Telor

      Telor is not a party to any material legal proceedings, and no proceedings
are known to be contemplated by governmental agencies.

Security Ownership of Certain Beneficial Owners and Management of Telor

      The  following  table  sets  forth  certain   information   regarding  the
beneficial  ownership  of Telor's  Stock as of April 15, 1996 by (i) each person
known by Telor to be the  beneficial  owner of more  than 5% of the  outstanding
Telor Stock, (ii) each current director, (iii) the individual serving as Telor's
Chief  Executive  Officer (the "CEO") during the fiscal year ended  December 31,
1995; (iv) one former  executive  officer who served as an executive  officer of
Telor  during the fiscal year but was not serving on December  31,  1995,  whose
salary and bonus earned during  fiscal 1995 exceeded  $100,000 (the CEO and such
former officer are referred to herein as the "Named  Executive  Officers");  and
(v) all of Telor's  executive  officers,  the one former executive officer named

investment power with respect to the shares of Telor Stock indicated.

      Meeting Attendance.  During the fiscal year ended December 31, 1995, there
were ten meetings of the Board of Directors,  and the various  committees of the
Board of Directors met a total of three times. Board member attendance  averaged
89% for all meetings  held by the Board of Directors  and the  committees of the
Board.

Election and Compensation of Directors

      Pursuant to Telor's  Certificate of  Incorporation  and Restated  By-laws,
each as amended,  the Board of Directors on March 23, 1995 voted to set the size
of the Board of  Directors at nine (9).  Upon and after the Merger,  the size of
the Board of Directors will be seven (7).

      Telor's Board of Directors is classified into three classes. Each director
is elected for a three year term,  with one class of directors  being elected at
each annual meeting of stockholders.  The Merger Agreement provides that Charles
L. Dimmler, III, Kevin J. Dougherty, Angus M. Duthie, John C. Garbarino, John K.
Herdklotz, Ph.D., Paul D. Paganucci and Craig C. Taylor will be the directors of
the  Surviving  Corporation.  Such  directors  will hold office until the annual
meeting of  stockholders  set forth  opposite  their names under "THE MERGER AND
RELATED  TRANSACTIONS - The Surviving  Corporation"  and until their  respective
successors  are duly chosen and qualified or until their earlier  resignation or
removal. See "THE MERGER AND RELATED  TRANSACTIONS - The Surviving  Corporation"
and "INFORMATION ABOUT OH+R - Executive  Officer,  Key Employees and Directors."
The Board of Directors has inquired of each such person and determined that each
will  serve  if the  Merger  is  consummated.  If any of  such  persons  becomes
unavailable for election, the Board of Directors may designate  substitutes.  At
the Effective  Time,  certain  stockholders  of Telor and OH+R will have entered
into a Voting Agreement which provides that such securityholders  agree to elect
at the 1996 annual meeting of the  stockholders  of Telor certain persons to the
Board of  Directors.  See "THE MERGER AND RELATED  TRANSACTIONS  - The Surviving
Corporation."

      Each director who is not an employee of Telor is  automatically  granted a
non-qualified stock option to purchase 1,200 shares of Telor's Stock, subject to
vesting,  on the date of his or her  election  or  appointment  to the  Board of
Directors  and, if certain  conditions  are  satisfied,  will  automatically  be
granted options on certain dates after that election or appointment.  See "Stock
Plans - 1993 Plan" below.  Additionally,  under the terms of the 1993 Plan, each
non-employee  director of Telor was, upon the consummation of the initial public
offering on May 18,  1993,  granted a  non-qualified  option to  purchase  1,200
shares of Telor Stock,  subject to vesting,  at an exercise  price of $81.25 per
share.  During 1995, such options became  exercisable as to 2,800 shares, but as
of April 15, 1996, no portion of any such option granted had been exercised.

      In January 1991, the Board of Directors  granted to Mr. Chappell an option
to purchase  700 shares of Telor Stock  under  Telor's  1988 Plan at an exercise
price of $2.50 per share in  connection  with his service as a director.  During
1995, the option became  exercisable for 35 shares and as of April 15, 1996, the
option was exercisable for 697 shares.  The remaining shares became  exercisable
in February  1996.  As of April 15, 1996,  Mr.  Chappell had not  exercised  any
portion of the option.

      Telor reimburses  directors for expenses  associated with their attendance
at meetings of the Board of Directors and committees of the Board.  In 1995, the
aggregate  amount of  reimbursement  for these expenses for directors as a group
was approximately  $33,200. Prior to February 16, 1994, Telor did not compensate
members  of the  Board  for  attendance  at the Board  meetings.  Effective  for
meetings  after  February  15,  1994,  Telor  paid and will pay  $1,000  to each
non-employee  director for in-person attendance at each scheduled Board meeting,
in addition to reimbursing those directors for expenses.  Employee directors did
not  receive  additional  compensation  for  serving on the Board of  Directors.
Effective for meetings on or after  January 31, 1995,  Telor paid and will pay a
fee of $500 to each non-employee director attending scheduled Board meetings via
teleconference.   In  1995,   the  aggregate   amount  of  these   payments  was
approximately   $43,000.   Also  effective  January  31,  1995,  Telor  may  pay
non-employee  directors  a fee of  $1,000  per  day  spent  on  Telor  business,
including meetings of committees of the Board of Directors,  if requested by the
Chief Executive Officer and approved by the Compensation  Committee, in addition
to reimbursing  those directors for expenses.  In 1995, the aggregate  amount of
these payments was approximately $2,500.

Employment and Consulting Agreements, Termination of Employment and Change in
Control Arrangements

      Telor has a consulting agreement with John K. Herdklotz, Ph.D. pursuant to
which Dr.  Herdklotz  serves as  Telor's  Acting  Chief  Executive  Officer  and
President.  Under the agreement,  Dr. Herdklotz is an independent contractor and
receives $800 per day for his services.  The agreement became effective November
14, 1994 and may be  terminated  by either  party as provided in the  agreement.
Under the agreement, Dr. Herdklotz agreed to provide services to Telor on an "as
needed"  basis,  which prior to January 1, 1995 was  approximately  two days per
week and during 1995 was generally full-time.  In accordance with the agreement,
Telor granted Dr.  Herdklotz a non-qualified  option to purchase 5,000 shares of
Telor's  Stock at the market  price of the stock on the date of the  grant.  See
"Option  Grants"  table below.  Telor also agreed to rent an  apartment  for Dr.
Herdklotz's  use as his residence in the Boston area, and to make monthly rental
payments of  approximately  $2,300 per month for that apartment.  In 1995, Telor
paid a total of $27,300  in rental  payments  and  $18,500  for Dr.  Herdklotz's
related income taxes.

      Telor had an employment  agreement with Dr. Neufeld  pursuant to which Dr.
Neufeld was employed as Executive Vice President and Chief Scientific Officer at
an initial annual salary of $150,000, subject to periodic review by the Board of
Directors.  Dr.  Neufeld's  annual rate of salary was $175,000 as of October 31,
1995, the date of his  resignation.  Upon his  resignation,  Dr. Neufeld entered
into an agreement with Telor,  providing for the  availability of Dr. Neufeld to
consult with Telor in connection  with Telor's  surgical miosis program or other
matters relating to services performed during his employment.  In the event that
Telor enters into a development  and /or license  agreement on or before June 1,
1996 with a corporate  partner for EY-128,  Dr.  Neufeld is to receive a $25,000
bonus  payment,  provided  that  he  actually  participates  in  explaining  the
technology of Telor during the agreement negotiations.

      The Named Executive  Officers are also subject to certain  confidentiality
and, except for Dr. Herdklotz,  non-competition obligations. Each is required to
disclose to Telor certain  inventions,  discoveries,  and  developments,  and to
assign his rights therein to Telor.

      Under Telor's 1988 Plan,  as in effect at certain  times in the past,  and
the 1993 Plan, if Telor is consolidated with or acquired by another entity,  the
Compensation  Committee or the board of directors of any entity that assumes the
obligations  of Telor  under  the  applicable  plan  may,  among  other  things,
terminate  all options in exchange  for a cash payment  equal to the  difference
between the fair market value of the shares then subject to purchase pursuant to
the options and the  purchase  price for such  shares  pursuant to the  options.
However,  such  provisions  do not apply to the  proposed  Merger.  The proposed
Merger  will not cause an  acceleration  of vesting of any options for any Named
Executive Officer.

     1995, of which 9,600 were granted to non-employee Directors and 35,585 were

(3)  The  exercise  price of each  option was equal to or greater  than the fair
     market value of Telor Stock on the grant date as  determined  in accordance
     with the 1993  Plan.  Under the terms of the 1993  Plan,  the  Compensation
     Committee may make  appropriate  adjustments  to the exercise  price of the
     outstanding  options  in the  event of  certain  stock  dividends  or stock
     splits,   which  may  result  in  a  reduction  of  the   exercise   price.
     Additionally,  the  Committee  may,  at its  discretion  and at the written
     request of the  optionee,  reduce  the  exercise  price of the  appropriate
     installments of an ISO in connection with the conversion of that optionee's
     incentive stock options (or any portion of them) to  non-qualified  options
     at any time prior to the exercise of the options.

(4)  Dr.  Herdklotz  received  non-qualified  stock  options for 800 shares that
     became  exercisable  in May  1995  and  for 800  shares  that  will  become
     exercisable on the date of the 1996 annual meeting of stockholders, subject
     to Dr.  Herdklotz's  continuing  service as a Director.  The  options  were
     granted at the closing  market price of Telor Stock on the grant date,  and
     have ten year terms. See "Election and Compensation of Directors" above.

(5)  Dr. Neufeld forfeited  options for an equal number of shares.  See" - Stock
     Plans" below.

the number of shares covered by both exercisable and unexercisable stock options
as of December 31, 1995, and the values of the "in-the-money" options as of that
date.  An option is  "in-the-money"  if the per share fair  market  value of the
underlying stock exceeds the option exercise price per share.

Stock Plans

      1988 Plan. Telor's 1988 Plan (the "1988 Plan") was adopted by the Board of
Directors and the  stockholders  of Telor on November 4, 1988 and amended by the
Board of Directors on March 13,  1996.  The 1988 Plan  provides for the grant of
incentive  stock  options  ("ISO's")  as defined  in Section  422 of the Code to
purchase shares of Telor Stock to employees of Telor and its affiliates, and the
grant of  non-qualified  stock  options  to  purchase  shares of Telor  Stock to
employees  and  directors  of, and  consultants  to,  Telor and its  affiliates.
Additionally,  under the 1988 Plan, awards of Telor Stock ("Awards") may be made
and  opportunities to make direct purchases of Telor Stock  ("Purchases") may be
provided to directors,  employees and  consultants of Telor and its  affiliates.
ISO's,  non-qualified stock options, Awards and authorizations to make Purchases
are referred to  collectively  as "Stock  Rights." Grants of Stock Rights may be
made to members of the Board of Directors  only in  accordance  with the special
procedures set out in the 1988 Plan.


                                      84

<PAGE>



      The exercise  price per share of ISO's granted under the 1988 Plan may not
be less than 100% of the fair market value of a share of Telor Stock on the date
of grant and in the case of ISO's  granted  to  holders  of more than 10% of the
voting  stock of Telor,  not less than  110% of the fair  market  value of Telor
Stock  on the date of  grant.  ISO's  granted  under  the  1988  Plan may not be
exercised  later  than ten years  from the date of grant,  and any ISO's held by
employees  who own more than 10% of the voting  stock of Telor on the grant date
may not be exercised  later than five years from the grant date.  The  aggregate
fair market value  (determined at the time of grant) of shares issuable upon the
exercise of ISO's granted to an optionee under any stock plan of Telor which are
exercisable  for the first  time  during  any one  calendar  year may not exceed
$100,000.

      Non-qualified  stock  options must be exercised no more than ten years and
one day from the grant date. The exercise price of  non-qualified  stock options
granted  under  the 1988  Plan may not be less  than the  lesser of (i) the book
value per share of Telor  Stock as of the end of the fiscal  year of the Company
immediately  preceding  the grant date,  or (ii) fifty percent (50%) of the fair
market value per share of Telor Stock on the grant date.

      Options  granted under the 1988 Plan are not  transferable  by an optionee
other  than  by  will  or by the  laws  of  descent  and  distribution,  and are
exercisable during an optionee's life time only by the optionee.

      Options granted under the 1988 Plan terminate as follows. If the holder of
an ISO ceases to be employed by Telor and its  affiliates,  other than by reason
of  death  or  disability,  his or her  ISO's  may be  exercised  to the  extent
exercisable  on the date of that  termination  for a period  of 90 days from the
termination  date.  If an ISO  optionee  ceases to be  employed  by Telor or its
affiliates by reason of his or her  disability or death,  any of the  optionee's
ISO's may be  exercised,  to the  extent  exercisable  on the date of his or her
termination  due to  disability  or death,  by the  optionee  or the  optionee's
estate, personal representative or beneficiary, as applicable for a period of up
to 180 days from the date of the optionee's termination due to disability or the
optionee's death, respectively. Notwithstanding the foregoing provisions of this
paragraph,  in no event may an option be  exercised  later  than the  originally
prescribed term thereof.  In the event of a proposed  dissolution or liquidation
of Telor,  each option  granted under the 1988 Plan will  terminate  immediately
prior to the  consummation  of that  proposed  event or at such  other  time and
subject to such other  conditions  as shall be  determined  by the  Compensation
Committee.

      The 1988 Plan is administered by the  Compensation  Committee.  Subject to
the terms of the 1988 Plan,  the  Compensation  Committee  has the  authority to
determine  the terms and  conditions  upon which Stock  Rights may be granted or
awarded,  including the recipients of the Stock Rights,  the type of Stock Right
to be granted or awarded, when the Stock Rights become exercisable, the price at
which  an  option  may be  exercised  or stock  may be  purchased  and,  whether
restrictions  should be placed on shares  subject to Stock  Rights,  and has the
authority to interpret the 1988 Plan. Options granted under the 1988 Plan may be
immediately  exercisable in full or may become  exercisable in installments over
the  period  specified  by the  Compensation  Committee.  Telor may  require  an
optionee, Award recipient or purchaser to pay withholding

                                      85

<PAGE>



taxes upon the  occurrence of certain events  relating to the Stock Rights,  and
the Compensation Committee may condition the exercise of an option, the grant of
an Award,  the making of a Purchase of Telor Stock for less than its fair market
value,  or the vesting of restricted  Telor Stock acquired by exercising a Stock
Right, on the grantee's  payment of such taxes.  Additionally,  the Compensation
Committee  generally  may  accelerate  the date of exercise  of any option.  The
Compensation  Committee  may, at an  optionee's  request,  convert an optionee's
ISO's into  non-qualified  stock  options and may impose such  conditions on the
non-qualified options as it may determine. The 1988 Plan will expire on November
4, 1998, subject to extension by the Board of Directors and the stockholders.

      A total of 48,453 shares of Telor Stock are  authorized for issuance under
the 1988 Plan. Upon  effectiveness of the Merger,  the number of shares of Telor
Stock authorized for issuance under the 1988 Plan will be reduced to 32,354.  As
of April 15, 1996, the one employee of Telor, all seven  non-employee  directors
of Telor, and all consultants to Telor (approximately 11 people, of whom two had
received  option grants) were eligible to  participate  in the 1988 Plan.  Three
former consultants also held unexercised  options.  As of that date, options for
22,179  shares had been  exercised  under the 1988  Plan.  Also as of that date,
options to  purchase a total of 12,800  shares of Telor  Stock were  outstanding
under the 1988 Plan at exercise  prices  ranging from $2.50 to $12.50 per share,
and  with  a  weighted  average  exercise  price  of  $7.77  per  share.  Of the
outstanding  options,  options  covering 9,695 shares were then exercisable at a
weighted  average  price  of $6.85  per  share.  The  outstanding  options  have
expiration  dates  ranging from August 31, 1996 to February  12, 2001.  No other
Stock  Rights  were  outstanding  as of  January  15,  1996,  and Telor does not
currently  expect to issue any additional  Stock Rights under the 1988 Plan. The
closing price of Telor Stock on April 15, 1996 was $5.75 per share,  as reported
on the Nasdaq National Market.

      On January 31, 1995, the Compensation  Committee of the Board of Directors
granted,  effective February 1, 1995 to all then current  employees,  options to
purchase  shares at the closing  market price of Telor Stock on January 31, 1995
("New  Options").  New Options  were  granted to each  employee  for a number of
shares equal to the number  subject to options held by that  employee on January
31, 1995 which had a per share  exercise price greater than the January 31, 1995
closing  price.  New  Options  were  subject  to written  acceptance  of certain
conditions  by each  employee,  including  the  forfeiture  by such  employee of
options for a number of shares  equal to the number  granted  under the accepted
New Options.  New Options for which the conditions were not accepted  expired on
February 17, 1995. New Options vest ratably over sixty months on the last day of
each month between February 1995 and January 2000,  inclusive,  have a per share
price of  $8.75,  and a term of ten  years,  expiring  January  31,  2005.  Four
employees,  including Dr.  Neufeld,  accepted New Options  totaling 2,520 shares
under the 1988 Plan.  No New Options have been  exercised.  A New Option for 501
shares is  outstanding,  with the balance  forfeited  by former  employees.  The
outstanding New Option expires on August 31, 1996.

      1993 Plan.  Telor's 1993 Plan was adopted by Telor's Board of Directors on
March 4,  1993,  amended  on March 5,  1993 and  approved,  as  amended,  by the
stockholders  of Telor on April 8, 1993.  The 1993 Plan was also  amended by the
Compensation Committee on March

                                      86

<PAGE>



23, 1995, and such amendments were approved by the  stockholders of Telor on May
10, 1995.  The 1993 Plan  provides for the grant of ISO's to purchase  shares of
Telor Stock to  employees,  and the grant of  non-qualified  options to purchase
shares of Telor Stock to employees and directors of, and  consultants to, Telor.
The 1993 Plan also provides that no  participant in the 1993 Plan may be granted
in any calendar  year options to purchase or receive more than 75,000  shares of
Telor Stock pursuant to the 1993 Plan.

      The 1993 Plan  also  provides  for the  automatic  grant of  non-qualified
options to directors who are not employees of Telor or of any of its  affiliates
("Outside Directors") under a formula set forth in the plan as follows: (i) each
of the six Outside  Directors on the date the initial  public  offering of Telor
Stock was consummated was granted, on such date, a non-qualified stock option to
purchase  1,200  shares of Telor Stock,  subject to vesting;  (ii) at the annual
meeting of  stockholders  held in May 1995 (the  "1995  Annual  Meeting"),  each
Outside  Director who had been in the  continued  and  uninterrupted  service of
Telor as a director for at least the  six-month  period  ending on such date was
granted a  non-qualified  stock  option to purchase  800 shares of Telor  Stock;
(iii) each Outside  Director  who is first  elected or appointed to the Board of
Directors after the date of the 1995 Annual Meeting will be granted, on the date
of such election or appointment,  a nonqualified  stock option to purchase 1,200
shares of Telor Stock,  subject to vesting;  and (iv) at each annual  meeting of
stockholders  or special  meeting in lieu  thereof on and after the 1995  Annual
Meeting,  each Outside Director who has been in the continued and  uninterrupted
service of Telor as a director for at least the  six-month  period ending on the
date of such meeting shall be granted a  non-qualified  stock option to purchase
800 shares of Telor Stock, subject to vesting (all such options are collectively
referred  to as  "Director  Options").  Director  Options  are  granted  with an
exercise  price per  share  equal to the fair  market  value of a share of Telor
Stock on the grant date (determined in accordance with the 1993 Plan), have a 10
year term,  and,  (a) in the case of options  granted  pursuant to (i) and (iii)
above,  will  become  exercisable  in  equal  installments  on the  first  three
anniversaries  of the  grant  date  provided  in each  case  that  the  optionee
continues  to serve as a director  of Telor until such  anniversary;  (b) in the
case of options granted pursuant to (ii) above,  are immediately  exercisable in
full; and (c) in the case of options granted pursuant to (iv) above, will become
immediately  exercisable  in full as of the date of the next  annual  meeting of
stockholders  or  special  meeting  in  lieu  thereof  (the  "Subsequent  Annual
Meeting") following the meeting at which the option was granted,  whether or not
reelected at such meeting, provided that such director has been in continued and
uninterrupted  service as a director of Telor from the date of grant through the
day prior to the Subsequent  Annual Meeting;  provided,  that, in the event of a
"Change of Control" (as defined in the 1993 Plan),  Outside  Directors  shall be
entitled to exercise all  Director  Options  immediately  prior to the Change of
Control (but subject to consummation  of such Change of Control)  whether or not
then vested, provided,  further,  however, that such acceleration of vesting and
exercisability  shall not occur if and to the extent  that  Telor's  independent
accountants  have advised the Board of Directors  that such  acceleration  could
prohibit  the  accounting  treatment  of the  transaction  which is a Change  of
Control as a pooling under APB Opinion No. 16 (or any successor opinion) and the
Board reasonably believes it is the intent of Telor to treat such transaction as
a pooling. In any event, the Merger does not qualify as a Change of Control.

      The terms upon which ISO's may be granted under the 1993 Plan (namely, the
minimum  exercise  price  thereof,  the maximum  amount  which may first  become
exercisable  during any calendar  year,  and the time period  within which ISO's
must be exercised)  are the same as those which apply to ISO's granted under the
1988 Plan. See "Stock Plans - 1988 Plan" above.  The option price for ISO's must
be paid in a medium  permitted by Section 422 of the Code,  as determined by the
Compensation  Committee.  The exercise  price per share of the shares covered by
non-qualified  stock  options  may not be less  than the par  value per share of
Telor Stock on the grant date.

      Options granted under the 1993 Plan are  exercisable in installments  over
the option  term,  in  accordance  with the terms of the  specific  stock option
agreement executed in connection with the grant of such option. The Compensation
Committee may, at its  discretion,  condition the exercise of an option for less
than the then fair  market  value of the  underlying  shares  on the  optionee's
payment  of  withholding  taxes.  Options  granted  under  the 1993 Plan are not
transferable  by an  optionee  other than by will or by the laws of descent  and
distribution or pursuant to a qualified  domestic  relations order as defined by
the Code or Title I of the Employee  Retirement Income Security Act or the rules
thereunder,  and are  exercisable  during an  optionee's  lifetime  only by such
optionee or by his or her legal representative.

      Options other than Director  Options granted under the 1993 Plan terminate
as follows,  except as otherwise provided in the applicable option agreement. In
the event of termination of service for any reason other than  termination  "for
cause" (as defined in the 1993 Plan),  disability or death,  options may only be
exercised to the extent exercisable on the date of termination, and, in the case
of ISO's,  may only be exercised within three months after  termination.  If the
optionee dies within three months of that termination,  his or her survivors may
exercise  the option  within one year  after the date of the  optionee's  death.
Moreover,  only if the applicable option agreement  specifically so provides, if
the Board of Directors of Telor  determines that the optionee engaged in conduct
that would  constitute  "cause"  after  that  optionee's  termination,  then the
optionee's  right to exercise  any option  granted  under the 1993 Plan would be
forfeited.  If an  optionee is  terminated  "for  cause"(as  defined in the 1993
Plan),  his or her options  will be  forfeited  immediately,  if the  applicable
option agreement  specifically so provides. In the event of the optionee's death
or disability,  options generally may be exercised by the optionee or his or her
legal  representative,  to the  extent  exercisable  on the  date  of  death  or
disability,  within up to one year  after the  optionee's  death or  disability.
Notwithstanding any of the foregoing  provisions of this paragraph,  in no event
may an option be  exercised  later  than its  originally  prescribed  term.  The
exercise  period of a Director  Option  terminates upon the first to occur of 10
years after the grant date or 90 days after the optionee ceases to be a director
of Telor (180 days if the  termination  is as a result of death or  disability),
and Director Options are exercisable only to the extent  exercisable on the date
of the director's cessation of service as a director.

      The  1993  Plan  provides  for  the  termination  of all  options  granted
thereunder in the event of a dissolution or liquidation of Telor, subject to the
rights of optionees  (or  optionees'  survivors)  to exercise all their  options
immediately  before  such event,  to the extent that the right to exercise  such
options  has  accrued as of the date  immediately  prior to the  dissolution  or
liquidation.  The 1993 Plan also provides that, if Telor is consolidated with or
acquired by

                                      88

<PAGE>



another  entity,  the  Compensation  Committee  or the board of directors of any
entity assuming the obligations of Telor under the 1993 Plan must either provide
for  continuation  of the  options  granted  under  the 1993  Plan,  notify  the
optionees  that their  vested  options must be  exercised  within the  specified
period of time or the options will be  terminated,  or terminate  all options in
exchange  for a cash  payment  equal to the  difference  between the fair market
value of the shares  then  subject to  purchase  pursuant to the options and the
purchase price for such shares pursuant to the options.

      The 1993 Plan is administered by the  Compensation  Committee.  Subject to
the terms of the 1993 Plan, and other than with respect to Director Options, the
Compensation  Committee has the authority to determine the terms and  conditions
upon which options may be granted under the 1993 Plan, including the individuals
to whom options may be granted,  the exercise price and number of shares subject
to each option, the time or times during which all or a portion of an option may
be exercised  and certain other terms and  conditions of options.  Additionally,
the Compensation  Committee generally may accelerate the date of exercise of any
option.  The Compensation  Committee may, at an optionee's  request,  convert an
optionee's ISO's into nonqualified  stock options.  The 1993 Plan will terminate
on February 16, 2003, unless  previously  terminated by vote of the stockholders
of Telor.

      On January 31, 1995, the Compensation  Committee of the Board of Directors
granted,  effective February 1, 1995 to all then current  employees,  options to
purchase  shares at the closing market price of Telor Stock on January 31, 1995.
New Options  were  granted to each  employee for a number of shares equal to the
number  subject to options held by that  employee on January 31, 1995 that had a
per share exercise  price greater than the January 31, 1995 closing  price.  New
Options  were  subject  to written  acceptance  of  certain  conditions  by each
employee,  including the  forfeiture by such employee of options for a number of
shares equal to the number  granted under the accepted New Options.  New Options
for which the  conditions  were not accepted  expired on February 17, 1995.  New
Options vest  ratably  over sixty  months on the last day of each month  between
February 1995 and January 2000,  inclusive,  have a per share  exercise price of
$8.75,  and a term of ten years,  expiring  January  31,  2005.  Six  employees,
including Dr.  Neufeld,  accepted New Options  totaling  16,406 shares under the
1993 Plan. No New Options have been exercised;  New Options for 2,108 shares are
outstanding, with the balance forfeited by former employees. The outstanding New
Options expire on or before November 29, 1996.

      The  total  number  of  shares of Telor  Stock  currently  authorized  for
issuance  under  the 1993  Plan is  140,000.  On March  18,  1996,  the Board of
Directors  voted to adopt and approve,  subject to  stockholder  approval at the
Special  Meeting,  an amendment to the 1993 Plan to increase by 105,000  shares,
from  140,000 to 245,000,  the  aggregate  number of shares of Telor Stock as to
which stock options may be granted under the 1993 Plan.  See  "PROPOSALS FOR THE
SPECIAL  MEETING  -  Proposal  2: 1993 Plan  Amendment."  As of April 15,  1996,
Telor's  one  employee,  all seven  non-employee  directors  of  Telor,  and all
consultants to Telor  (approximately 11 people, of whom nine had received option
grants) were eligible to participate in the 1993 Plan. As of that date,  options
to purchase a total of 33,900 shares of Telor Stock were  outstanding  under the
1993 Plan, with exercise prices ranging from $8.75 to $81.25 per

                                      89

<PAGE>



share,  and with a weighted  average  exercise price of $27.45 per share. Of the
outstanding  options,  options  covering 19,296 shares were  exercisable on that
date,  with  a  weighted  average  exercise  price  of  $32.89  per  share.  The
outstanding  options have  expiration  dates ranging from August 31, 1996 to May
10,  2005.  The  closing  price of Telor  Stock on April 15,  1996 was $5.75 per
share, as reported on the Nasdaq National Market.  All employees,  directors and
consultants of the Surviving  Corporation will be eligible to participate in the
1993 Plan.

      In 1995,  options  were  granted,  including  grants to a Named  Executive
Officer. See "Executive Compensation - Option Grants" above.

Federal Income Tax Considerations with respect to Stock Plans

      The  following  is a  description  of  certain  U.S.  federal  income  tax
consequences  of the issuance  and  exercise of options  under the 1988 Plan and
1993 Plan:

      Incentive  Stock  Options.  An  incentive  stock option does not result in
taxable  income to the  optionee or deduction to Telor at the time it is granted
or exercised, provided that no disposition is made by the optionee of the shares
acquired  pursuant  to the option  within two years  after the grant date of the
option nor within one year after the date of issuance of shares to the  optionee
(the "ISO holding  period").  However,  the  difference  between the fair market
value of the stock on the date of exercise and the option price therefor will be
an item of tax preference  includable in "alternative  minimum taxable  income."
Upon  disposition of the stock after the  expiration of the ISO holding  period,
the optionee will  generally  recognize  long term capital gain or loss based on
the difference  between the  disposition  proceeds and the option price paid for
the  stock.  If the  stock is  disposed  of prior to the  expiration  of the ISO
holding period, the optionee will generally recognize taxable compensation,  and
Telor  will  generally  have  a  corresponding  deduction,  in the  year  of the
disposition,  equal to the excess of the fair  market  value of the stock on the
date of  exercise  of the option  over the option  price.  Any  additional  gain
realized on the disposition will normally constitute capital gain. If the amount
realized  upon such a  disqualifying  disposition  is less than the fair  market
value of the stock on the date of exercise,  the amount of  compensation  income
will be  limited  to the  excess  of the  amount  realized  over the  optionee's
adjusted basis in the stock.

      Non-Qualified Stock Options.  The grant of a non-qualified option will not
result in taxable  income to the  optionee or  deduction to Telor at the time of
grant.  The  optionee  will  recognize  taxable  compensation,  and  Telor  will
generally have a corresponding  deduction, at the time of exercise in the amount
of the  excess of the then fair  market  value of the shares  acquired  over the
option  price.  Upon  disposition  of the shares,  the optionee  will  generally
realize capital gain or loss, and his or her basis for determining  gain or loss
will be the sum of the  option  price  paid for the  stock  plus the  amount  of
compensation income recognized on exercise of the option.

      Restricted  Stock.  The sale of stock  received  on  exercise  of  options
granted under the 1988 Plan and the 1993 Plan at a profit may, in certain cases,
subject  certain  participants to liability under Section 16(b) of the 1934 Act.
In that case, the time for determining and  recognizing  compensation  income to
the participant will be postponed until the Section 16(b)

                                      90

<PAGE>



restrictions are no longer applicable. However, the participant may elect within
30 days of acquiring the stock to determine and recognize compensation income as
if such restrictions did not exist.

Section 16(a) Reporting Delinquencies

      Section 16(a) of the Exchange Act requires Telor's directors and executive
officers, and persons who beneficially own more than 10% of Telor Stock, to file
with the SEC initial  reports of  beneficial  ownership  on Forms 3,  reports of
changes in beneficial  ownership on Forms 4 and annual  statements of beneficial
ownership on Forms 5 regarding  their holdings and  transactions  in Telor Stock
and other Equity Securities of Telor.  Officers,  directors and greater than 10%
beneficial owners are required by SEC regulation to furnish Telor with copies of
all Section 16(a) forms they file.

      To Telor's  knowledge,  based solely on review of the copies of such forms
and written  representations  that no other  reports were  required,  during the
fiscal year ended  December 31,  1995,  all of these  filing  requirements  were
satisfied.

      Forms 5 are not required to be filed if there are no previously unreported
transactions or holdings to report. Nevertheless,  Telor is required to disclose
the names of directors, executive officers and 10% stockholders who did not file
a Form 5, unless Telor has obtained a written statement from each such director,
executive officer and 10% stockholder that no filing is required.  Either a copy
of a Form 5 filing or a written  statement  that no such filing is required  has
been received from each director, executive officer and 10% stockholder.

Telor's Management's  Discussion and Analysis of Financial Condition and Results
of Operations

      Since its inception in April 1988,  Telor has been engaged in research and
development of products for use in ophthalmic  surgery and age-related  diseases
of the eye.

      On August 9, 1995, Telor announced that its preliminary  analysis of Phase
III clinical trials of its lead product  candidate,  XARANO,  indicated that the
trials  did  not  support   continuation  of  the  XARANO  development  program.
Separately,  Telor also announced  positive results of its Phase I/II trial of a
compound to reduce surgical miosis, a problem  associated with cataract surgery.
On August 30, 1995, Telor announced a restructuring  with a workforce  reduction
designed to substantially reduce Telor's rate of cash use for operations.  Telor
also  announced  its  intention  to find and  evaluate  business  opportunities,
potentially including identifying a merger candidate, seeking corporate partners
to support the clinical program for surgical miosis, or exploring a new business
direction. Telor also terminated its research and development activity.


                                      91

<PAGE>


      On December 7, 1995,  Telor announced the signing of a letter of intent to
merge with OH+R. Subsequently, on February 23, 1996, Telor announced the signing
of the Merger  Agreement.  Also, Telor is continuing to seek a corporate partner
to support the clinical  program for the development of EY-128 for the treatment
of surgical miosis.

     Telor is  actively  seeking to obtain a  sublessee  or  sublessees  for its
leased  facility in  Wilmington,  Massachusetts,  or to  terminate  the lease by
securing a replacement  lessee or lessees and has signed a nonbinding  letter of
intent with one  potential  sublessee and has a verbal  understanding  of intent
with another potential sublessee.  Telor currently anticipates that a lease with
one sublessee  will be signed on or about the date hereof,  subject to obtaining
written consent to the sublease from the landlord, with rent payments commencing
60 days after the date such  consent  is  obtained.  With  respect to the second
potential  sublessee,  negotiations  are  proceeding,  but no estimated  date of
signing can be made.  Further,  Telor cannot  predict if and when either of such
leases will be concluded or that the negotiations will result in favorable terms
for Telor.

      By November 30,  1995,  Telor had reduced its  workforce to one  full-time
employee.  Telor's  Acting  Chief  Executive  Officer and Telor's  former  Chief
Scientific Officer continue to serve Telor on a consulting basis.

      Telor has not derived  revenues  from the sale of any products or services
and does not expect to derive revenues from the sale of any products or services
in the  absence  of the  Merger or sale of rights to the  clinical  program  for
surgical  miosis.  As of December  31,  1995,  Telor's  accumulated  deficit was
$31,067,000.

      Results of Operations

      The net loss for the years  ended  December  31,  1993,  1994 and 1995 was
$6,801,000,  $8,960,000 and $7,555,000,  respectively.  Excluding  restructuring
charges for the years ended  December 31, 1994 and December 31, 1995 of $609,000
and  $2,000,000,  respectively,  the net loss for the years ended  December  31,
1993, 1994 and 1995 was $6,801,000, $8,351,000 and $5,555,000, respectively. The
increase  from 1993 to 1994  reflected  increases  in research  and  development
expenses  and  the  expansion  of  administrative  staff  in  support  of  those
activities.  The decrease from 1994 to 1995 reflected the termination of Telor's
two lead programs, TEKRON in November 1994 and XARANO in August 1995.

      Research and development  expenses increased in each period from inception
through the termination of the TEKRON program in November 1994,  increasing from
$5,501,000  in the year ended  December 31, 1993 to $7,047,000 in the year ended
December  31,  1994.  With  the  termination  of the  TEKRON  program,  expenses
continued at a reduced rate, declining to $3,732,000 for the year ended December
31, 1995. The increase in the year ended December 31, 1994 was due to continuing
Phase  III  clinical  trials  for  XARANO  and the  commencement  of  additional
preclinical  programs.  The decrease in the year ended December 31, 1995 was due
to the  termination  of the TEKRON  program in November 1994 and the  consequent
restructure,  and to the  termination of the XARANO  programs in August 1995 and
the  consequent  restructure.  Research and  development  expenses for 1995 were
chiefly for the XARANO Phase III clinical trials.


                                      92

<PAGE>



      General and administrative  expenses increased from $1,452,000 in the year
ended  December  31,  1993 to  $1,733,000  in the year ended  December  31, 1994
primarily due to expanded facility costs,  professional and consulting services,
and additions to personnel in business development and finance,  particularly as
a result of expenses  associated with being a public  company.  In October 1994,
Telor  relocated  to a new and larger  facility  in  Wilmington,  Massachusetts.
General and  administrative  expenses  increased to $2,206,000 in the year ended
December 31, 1995 due partly to costs related to this new facility. In addition,
with the curtailment of all research and development activities after the XARANO
program  termination,  certain  continuing costs formerly a part of research and
development activities were classified as general and administrative.

      Marketing  expenses  declined from $318,000 in the year ended December 31,
1993 to $193,000 in the year ended  December 31, 1994.  With the  termination of
the TEKRON program in November 1994, Telor  re-evaluated its marketing and sales
strategy and terminated its marketing  efforts.  Telor had no marketing expenses
in the year ended December 31, 1995.

      The  restructuring  charge for the year ended  December 31, 1995  included
$640,000 for severance  and related  costs,  an allowance of $1,100,000  for the
write-down of fixed assets to net realizable value, and $260,000 for anticipated
costs associated with obtaining a sublessee or sublessees or replacement  lessee
or lessees  for Telor's  leased  facility in  Wilmington,  Massachusetts.  As of
December  31, 1995,  $356,000 of  restructuring  costs were  included in accrued
expenses,  chiefly  related to costs  associated  with the Wilmington  facility.
Except for  leasehold  improvements,  substantially  all of Telor's fixed assets
have been sold.

      Net interest income was $470,000, $622,000 and $383,000 in the years ended
December 31, 1993, 1994 and 1995,  respectively.  The increase in the year ended
December  31,  1994 was due to higher  average  cash and  short-term  investment
balances and rising rates of return. The decrease in the year ended December 31,
1995 was due to declining cash and short-term  investment balances as funds were
utilized for operations.

      No material trends,  events or transactions have arisen since December 31,
1995, that would  materially  affect Telor's  financial  condition or results of
operations.

      Liquidity and Capital Resources

      At December 31, 1995,  Telor had cash,  cash  equivalents  and  short-term
investments of $5,292,000, a decrease of $5,653,000 from $10,945,000 at December
31,  1994.  Telor has financed its  operations  to date from its initial  public
offering  receipts in May and June of 1993,  prior private  placements of equity
securities  and  convertible  debt  securities,   and  investment  income.  From
inception  through  December  31,  1995,  Telor's  paid-in  capital  amounted to
approximately  $35,653,000 consisting primarily of proceeds from these financing
sources.

      There were no capital  expenditures  for the quarter  ended  December  31,
1995. For 1995,  capital  expenditures  were $8,000 as compared to $1,119,000 in
1994  and  $248,000  in  1993.  Telor  moved  to  its  facility  in  Wilmington,
Massachusetts  in October 1994,  accounting for both the level of expenditure in
1994 and the substantially reduced capital expenditure level after the move. The
refocus  of  resources   associated  with  announced   restructurings   in  1995
significantly reduced the level of expenditure in 1995.


                                      93

<PAGE>



      Substantial  additional  funds  may  be  required  to  support  continuing
operations  subsequent to completion of the Merger with OH+R.  See  "INFORMATION
ABOUT OH+R - OH+R's Management's  Discussion and Analysis of Financial Condition
and Results of Operations."  The  availability of funds to support the Surviving
Corporation's   operations   thereafter  cannot  be  predicted.   The  Surviving
Corporation   may  choose  to  continue   seeking   additional   funds   through
collaborative  arrangements or joint ventures or from other sources,  including,
as market  conditions  permit,  equity or debt  financing.  It may seek to raise
funds when conditions are favorable,  even if it does not have an immediate need
for such  additional  capital at such time.  There can be no assurance that such
funds will be available on favorable  terms,  if at all.  Failure to obtain such
funds in the future may require the Surviving  Corporation to delay its plans to
expand or to scale back or eliminate some or all of its future operations.

      In the absence of the  Merger,  Telor's  capital  resources  and  interest
earned on invested capital will be sufficient to fund operations throughout 1996
and an evaluation of other alternatives.

      The foregoing discussion and analysis contains forward-looking  statements
within the meaning of Section 27A of the  Securities  Act and Section 21E of the
Exchange Act and are intended to be subject to the  "safe-harbor"  provisions of
the  Private  Securities  Litigation  Reform  Act of 1995.  The  forward-looking
statements  are subject to many risks and  uncertainties.  Included  among those
risks and  uncertainties  are those  discussed  above in this section,  "Telor's

                            INFORMATION ABOUT OH+R

Introduction

      OH+R develops, owns and operates multidisciplinary,  outpatient healthcare
centers for the prevention,  treatment and management of  work-related  injuries
and  illnesses.  OH+R currently  operates nine centers in the Northeast:  two in
Rhode Island,  two in Massachusetts,  three in Vermont and two in Maine.  OH+R's
centers  provide  high quality  patient care and a high level of service,  which
combined reduce workers' compensation costs for employers.

      The most effective way to reduce workers'  compensation cost is to prevent
injuries from occurring.  OH+R's centers offer a full array of services designed
to  reduce  the  frequency  and  severity  of  work-related  injuries,  such  as
pre-placement examinations, drug testing and work-site safety programs.

      OH+R's  treatment  approach is based on  documented  proprietary  clinical
protocols and integrates state-of-the-art medical, rehabilitation, psychological
and case  management  services  in a  "one-stop  shop"  focused on  solving  the
problems of both employers and employees. Employers' costs are reduced and their
workers  are  back  on the job  more  quickly  compared  to  national  averages.
Employees  receive better care,  maintain a positive attitude and have a greatly
reduced probability of developing chronic problems.

      The  following  description  of OH+R contains  forward-looking  statements
within the meaning of Section 27A of the  Securities  Act and Section 21E of the
Exchange Act and are intended to be subject to the  "safe-harbor"  provisions of
the Private Securities  Litigation Reform Act of 1995. Among the forward-looking
statements   is  a   statement   regarding   OH+R's   expansion   plans.   These
forward-looking  statements  are  subject  to many risks and  uncertainties,  as
discussed  below and  elsewhere  in this  Offering  Memorandum/Proxy  Statement,
particularly  in "RISK  FACTORS,"  that  could  cause  actual  results to differ
materially from the statements.

Market Overview

      Work-related  injuries and  illnesses  are a large and rapidly  increasing
source of lost  productivity  and  rising  costs for  businesses  in the  United
States. In 1994, workers'  compensation costs in the U.S. totaled  approximately
$70  billion - more than double the 1985 total of $30  billion.  These costs are
projected  to  double  again  by  the  year  2000.   Medical   costs   represent
approximately  40  percent  of  these  direct  costs  with the  remainder  being
principally  wage  replacement  (indemnity)  costs.  Not  accounted for in these
figures are the indirect costs, such as lost productivity,  hiring and training,
which  are  estimated  to be three to four  times the  amount  of direct  costs.
Workers'  compensation costs in the Northeast were approximately $8.2 billion in
1994. Medical expenses represented approximately $3.2 billion of these costs.

      The reasons for the escalation of workers'  compensation costs are complex
and multifaceted:


                                      95

<PAGE>



     o    Lack of proper injury prevention and employee education programs

     o    Inappropriate management of injured employees

     o    Lack of proper  medical and  rehabilitation  systems to treat  injured
          workers

     o    Lack of physicians  properly  trained and specializing in work-related
          injuries and illnesses

     o    Disincentives   for  quality  medical   providers  to  treat  workers'
          compensation patients

     o    Lack of coordination among the employer, employee and care providers

     o    No co-payment or deductibles to encourage moderate use of medical care

     o    Shifting  of medical  costs from group  health  plans to the  workers'
          compensation system

      The  rapid  increase  of  workers'  compensation  costs  has  resulted  in
employers  taking  a more  active  role in  preventing  and  managing  workplace
injuries.  This employer  involvement  typically  includes the  establishment of
safety committees,  emphasis on ergonomics in the workplace, and drug testing to
reduce the number of injuries; establishment of preferred provider relationships
to insure prompt and appropriate  treatment of work-related  injuries;  and, for
larger employers, becoming self-insured to capture savings from their efforts to
reduce and better manage injuries.

      The  occupational  healthcare  market  is  highly  fragmented,  consisting
primarily of individual or small-group  practices and  hospital-based  programs.
Greater capital  requirements,  the need for more  sophisticated  management and
marketing, and changes in the competitive  environment,  including the formation
of larger integrated networks such as OH+R's, have created increased interest in
affiliating with larger,  professionally managed  organizations.  As a result of
these factors, OH+R believes that there is an opportunity to consolidate private
practices and hospital programs in the Northeast.

Strategy

      OH+R's  objective  is to  develop  a  comprehensive  regional  network  of
occupational  healthcare  centers dedicated to reducing the cost of work-related
injuries through high-quality care and outstanding service.

      OH+R intends to build its network of centers through:

     o    Joint ventures with and acquisitions of existing hospital occupational
          health departments.

                                      96

<PAGE>




     o    Acquisitions of existing  physical therapy and  occupational  medicine
          practices.

     o    Strategic  alliances with group health insurers and health maintenance
          organizations (HMOs).

     o    Start-up of OH+R centers in strategic locations.

Subsequent to acquisition or joint venture,  new centers are converted to OH+R's
operating  model  through   implementation  of  OH+R's  clinical  protocols  and
operating  procedures.  New  services  are added as required  to provide  OH+R's
full-service offering.

      OH+R's operating strategy is based upon:

     o    Integration  of Services - Close  management and  coordination  of all
          aspects of an injured  worker's  care is  essential  to  ensuring  the
          earliest  possible  return to work.  Management and  coordination  are
          difficult,  if not impossible,  when clinicians are not working within
          an integrated  system.  A "one-stop  shop"  significantly  reduces the
          number  of  communications  required  for a given  case and  eases the
          coordination effort, while enhancing patient convenience.

     o    Quality  Care  and  Outstanding  Service  - For a number  of  reasons,
          injured  workers  often receive  second-class  care. A lack of quality
          care is costly to both the worker (ambiguous diagnosis,  undefined and
          open-ended  treatment  plans,  longer  recovery time) and the employer
          (increased lost work days). OH+R is committed to providing outstanding
          service -- to patients,  to employers and to third  parties.  From van
          pick-ups  for  injured  workers  to  custom  services   addressing  an
          employer's  specific  needs,  OH+R  attempts  to deliver  the level of
          service that is expected  from  companies  noted for great service but
          not always provided by healthcare providers.

     o    Outcome  Tracking  and  Reporting - All aspects of the OH+R system are
          focused on achieving successful outcomes -- cost-effectively returning
          injured  workers  back  to  the  job  as  quickly  as  possible  while
          minimizing  the risk of  re-injury.  Since the  inception of its first
          center,  OH+R has tracked  outcome  statistics.  OH+R  believes  these
          extensive outcome statistics demonstrate its ability to return injured
          workers  back to the job for costs  substantially  below the  national
          average.

     o    Low Cost Provider - OH+R believes that future success in virtually any
          segment of healthcare  services will require  delivery of quality care
          at the lowest possible price.  OH+R believes it is a low cost provider
          and  continuously  is working to further  reduce the cost of providing
          care through utilizing the lowest cost staff with the requisite skills
          and  increasing  the  productivity  of clinicians  and  administrative
          personnel.  OH+R routinely refines and revises its documented clinical
          protocols  and   operational   systems  to  increase   efficiency  and
          effectiveness.


                                      97

<PAGE>



     o    "At  Risk"   Reimbursement  -  OH+R  believes  that  case  rates  (per
          diagnosis),   capitation  (fixed  fee  per  employee  per  month)  and
          eventually  outcome-based   reimbursement  (higher  reimbursement  for
          better outcomes,  lower  reimbursement for worse outcomes) will become
          more  prevalent  in  workers'  compensation.  OH+R  offers case rates,
          capped fee-for-service programs and other innovative pricing programs,
          which  differentiate  OH+R from its  competitors.  OH+R  believes  its
          outcome data and management  information systems enable it to properly
          price and manage "at risk"  reimbursement  programs,  enhancing OH+R's
          profitability while providing increased  accountability for results to
          client employers.

Services

      OH+R  provides  a  "one-stop  shop"  for  the  prevention,  treatment  and
management  of  work-related  injuries and  illnesses.  Centers are staffed with
multidisciplinary    teams,   including   physicians,    physician   assistants,
psychologists,  physical and occupational therapists, exercise physiologists and
athletic trainers, as well as a manager, a client relations director and support
personnel. Each center also establishes relationships with local specialists for
the provision of needed  services.  Four of OH+R's centers,  which were added to
OH+R's network  during 1995, are in the process of converting  from centers that
provide either rehabilitation  services or medical services to OH+R's integrated
operating model.

      The clinicians at OH+R's centers  specialize in work-related  injuries and
illnesses and are trained to implement the OH+R system. The OH+R system consists
of an  integrated  set of  proprietary  protocols  for  every  aspect  of injury
treatment and  management  from the initial visit  through  return to work.  The
philosophy  of the system is best  summarized as a sports  medicine  philosophy.
Over the last five  years of its  evolution,  the OH+R  system  has been  proven
effective in reducing lost work days.  The  principal  tenets of the OH+R system
are:

     o    Prevention  - The least  costly  work-related  injuries are those that
          never  happen.  OH+R offers a full range of  prevention  programs from
          on-site job analysis to back schools and vaccination programs.

     o    Early,  Appropriate  Care - An injured  worker  should be evaluated as
          soon as possible  after an injury and receive  appropriate  treatment.
          Early  intervention  is critical  for "damage  control" and to get the
          injured worker on the right track, physically and psychologically, for
          early return to work.

     o    Objective Testing - In addition to identifying the minority of injured
          workers  who are  malingerers,  objective  testing  is  important  for
          determining starting points, measuring progress and focusing treatment
          on physical findings and functionality rather than complaints of pain.

     o    Active  Rehabilitation  -  Early  mobilization,  active  exercise  and
          goal-oriented rehabilitation are most effective in restoring function.

                                      98

<PAGE>




     o    Time-limited  Rehabilitation  -  Physical  and/or  functional  therapy
          provides diminishing returns after a certain amount of time, depending
          on the type of injury. To control cost, therapy must be stopped when a
          patient has reached maximum medical improvement.

      Specific services provided by OH+R include:

      Prevention

      Pre-placement   Exams  are  recommended  for  all  employees   within  job
categories that traditionally  have a high incidence and cost of injury.  Unlike
other pre-placement exams, objective testing, such as the B-200 back evaluation,
is used by OH+R to assist in determining an employee's physical capabilities for
proper job placement. Test results also document baseline capabilities which are
useful in the event of a future injury.

      Drug  and  Alcohol  Testing  is  mandated  for  many  workers  by  federal
regulations.  In addition,  employers are generally  utilizing  drug and alcohol
testing  more  frequently  as a tool to reduce the  frequency  and  severity  of
work-related injuries.

      Annual  Physicals  are used as part of an  overall  wellness  program  and
facilitate early detection of potentially serious health problems.

      Health Surveillance Programs are designed to meet regulatory  requirements
such as Department of  Transportation  physicals and physical  examinations  for
railroads,  airlines and the like.  OSHA  mandates  many other  programs such as
respiratory physicals.

      Americans With Disabilities Act (ADA) Compliance Services assist employers
in  identifying  essential job  functions.  OH+R's  specially  trained staff has
extensive experience in determining essential job functions and assisting in the
development of formal job descriptions.

      On-Site Job Analysis may be performed to assist in identifying  reasonable
accommodations for disabled individuals as part of ADA Compliance Services or to
evaluate a job or work station for safety purposes as a preventive measure.

      Wellness and Education  Programs are important to controlling and reducing
workers'  compensation  costs.  On-site  education  programs such as proper body
mechanics, back schools or patient handling techniques may be customized to meet
the needs of specific organizations.

      Medical Review Officers,  in compliance with the drug testing protocols of
the National  Institute on Drug Abuse (NIDA),  are responsible for  interpreting
the results of any negative or positive  drug tests to explain a  false-positive
test  result   ensuring  that  the  patient  does  not  become  a  victim  of  a
false-positive test result.

      Occupational  Health  Consulting  assists  industrial  relations people to
understand  complex  medical  issues,  such as AIDS, drug testing issues and the
ADA.

                                      99

<PAGE>




      Travel  Medicine  assists  companies  that  require  employees  to  travel
overseas and need to coordinate  immunizations  along with other  travel-related
medical needs.

      In-house or On-site  Health  Surveillance  Programs  include many services
listed above but which are provided more efficiently at the employer's location.

      Treatment

      Urgent/Medical  Care provides immediate access to specialized medical care
for work-related injuries and illnesses. The occupational medicine physicians at
OH+R  centers  provide  timely,  quality  care  to  injured  employees  that  is
cost-effective and avoid inappropriate treatment.

      Rehabilitation  Programs are utilized  when  appropriate  and necessary to
assist  in  the  return-to-work  effort.  Physical  therapy,  hand  therapy  and
functional  therapy (job simulation) are provided to injured  employees  through
defined programs that are goal-oriented and time-limited. OH+R employs a "sports
medicine"  approach  to  rehabilitation.  As with  other  athletes,  "industrial
athletes"   require  early   intervention,   active   exercise  and  the  proper
motivational  atmosphere to get them "back in the game" as quickly and safely as
possible.

      OH+R's   physical   therapy   approach   emphasizes    strengthening   and
reconditioning. Therapeutic exercise is the primary modality with minimal use of
passive modalities such as heat and ultrasound.

      Hand  therapy  encompasses  a variety  of  modalities  and  splinting  for
musculoskeletal  problems  of the hand and other  upper  extremities.  In recent
years,  demand for hand  therapy  has  increased  due to the  increase in carpal
tunnel and cumulative repetitive trauma diseases.

      Job simulation  activities are designed to replicate the primary  physical
tasks of a specific  job. For injured  employees  who are out of work or on very
light,  modified duty,  job simulation is provided to more precisely  strengthen
muscles  relevant to the job,  to train the  employee  in proper  techniques  to
prevent re-injury and to maintain a "working" frame of mind.

      Management

      Proper  management  of  work-related  injuries  is an  essential  part  of
successfully returning injured employees to productivity. OH+R's case management
system consists of two distinct components:

      Case  Management  provides  critical  communications  to all "key" players
involved in the  return-to-work  effort,  including the  employee,  employer and
insurance representative.

      Care Management encompasses control and coordination of all aspects of the
injured  employee's  care.  OH+R's medical and  rehabilitation  team members are
located in the same  facility  and work within an  integrated  system of formal,
defined protocols.  This approach allows superior,  ongoing  communication among
clinician team members regarding the most appropriate

                                      100

<PAGE>



treatment plan and eliminates  "system delays" (i.e., time lost as patients deal
with several, unrelated providers).

      Other Services

      For those  injured  employees  who are not OH+R  patients,  the  following
services are available to assist  employers in determining  the proper course of
action:

      Independent Medical Exams can be arranged through OH+R with an appropriate
specialist to determine a worker's  physical  capabilities and ability to return
to work if the employee is not in an OH+R treatment program.

      Fitness for Duty Exams  provide an  objective  assessment  of a previously
injured  employee's  capability  to  safely  return  to a  current  or  new  job
assignment.  Exams are scheduled as quickly as possible  following  release from
treatment by the  employee's  treating  physician  to safely  return the injured
employee to work.

      Functional  Capacity  Evaluations (FCE) provide  valuable,  objective data
regarding an injured  employee's  ability to perform critical job demands.  OH+R
focuses on the requirements of the job and what an employee is capable of doing.
Most other FCE providers use long,  costly systems that have little relevance to
an employee's job and focus on what the person cannot do.

Operations

      Medical and other  professional  services at OH+R's  centers are  provided
through independently organized professional  corporations or licensed satellite
clinics that enter into  management  agreements  with OH+R. OH+R provides a wide
array of business services under these management agreements,  such as providing
personnel,   practice  and  facilities   management,   billing  and  collection,
accounting,  tax and  financial  management,  human  resource  management,  risk
management,  marketing and information-based services such as process management
and outcomes analysis.  OH+R provides services under these management agreements
as an independent  contractor,  and the medical  personnel at the centers retain
sole responsibility for all medical decisions.

Marketing

      OH+R markets through a direct sales force primarily to employers, but also
to insurers and third-party  administrators.  These parties  strongly  influence
(and in many  instances  direct)  an injured  worker's  choice of  provider.  In
addition,  employers select providers for prevention services.  The direct sales
effort is  supported by direct mail  programs,  selective  advertising  and by a
strong public  relations  effort  focused on  reinforcing  OH+R's  position as a
leader in the field.


                                     101

<PAGE>



      The client  relations  director (CRD) of each center directs the marketing
effort.  The CRD also handles client service  problems,  client training and the
development of customized  services to address  unique client needs.  CRDs often
have  some  experience  in  healthcare,  preferably  as  salespersons  of health
services or pharmaceuticals.

Expansion Plan

      OH+R's  objective is to build a comprehensive  regional network of centers
through joint venturing,  acquiring practices, entering into strategic alliances
and  establishing  start-up  centers.  Because of the many  factors  involved in
building such a network,  there can be no assurance that OH+R will be successful
in meeting its  expansion  goals.  See "RISK  FACTORS" and  "-Important  Factors
Regarding Forward-Looking Statements."

      OH+R's  intended  principal  method of  expansion  is entering  into joint
ventures with and acquiring hospital  occupational  health programs,  which will
then be converted to  full-service  OH+R  centers.  OH+R also intends to acquire
private physical therapy and occupational health practices.

      The key criteria for evaluating joint ventures and acquisitions are:

      o      Market share and reputation in local markets

      o      Sources of patient flow

      o      Current philosophy of care

      o      Willingness to implement the OH+R system

      o      Range of services provided

      o      Ease of conversion/addition of services

      With respect to hospital occupational health programs, most have developed
by default.  Employers and injured  employees have naturally looked to the local
hospital for treatment of work-related  injuries. In addition, as OSHA and other
safety and health  regulations  came into  existence,  hospitals  again were the
logical (and often only) place for employers to turn for service.

      The typical  hospital  occupational  health  program was organized  when a
staff member was charged with coordinating  services from separate  departments,
had a marketing  brochure  printed,  and then  attempted to attract more of this
business.

      Given the  unplanned  development  of most  hospital  occupational  health
programs and the fact that the majority of the services offered are delivered by
functional departments where occupational health volume is a small percentage of
services rendered, it is not surprising that

                                     102

<PAGE>



these  programs  tend to be "second  class  citizens"  and unable to provide the
level of  service  to  either  the  employer  or the  employee  that a  focused,
dedicated  organization can provide. This inability is a significant weakness to
be exploited in the increasingly competitive healthcare arena.

      By affiliating with OH+R, hospitals benefit by:

      o   Access to OH+R's regional network of multi-location clients

      o   OH+R's  expertise in  delivering  high  quality  care and  outstanding
          service which enhances a hospital's reputation with employers

      o   OH+R's  entrepreneurial  work environment that provides incentives for
          performance such as bonuses and stock options

      o   Off-campus facilities providing outposts in geographic market segments
          that can generate inpatient referrals

      o   Minimizing capital requirements

      There are approximately 1500  hospital-based  occupational health programs
in the United  States,  300 of which are in the New England and Middle  Atlantic
states.

      Hospital  affiliations allow OH+R to leverage the name and position of the
institution within a community to ease market entry and expedite building market
share.  In  addition,  as  healthcare  reform  proceeds,  either with or without
government intervention,  integrated healthcare delivery systems are expected to
develop around networks of hospitals. Employers will contract with these systems
to provide for all the healthcare needs of their employees,  including treatment
of work-related injuries and illnesses.  It is strategically  important for OH+R
to have links to these systems to be  well-positioned to become the occupational
health provider for a system.

      OH+R's  first joint  venture is a  partnership  with an  affiliate  of New
England  Baptist  Hospital,  a  leading  hospital  in the  Boston  area  for the
treatment  of  musculoskeletal  injuries.  As part of this joint  venture,  OH+R
currently  manages two centers in the greater  Boston  area.  OH+R is  currently
discussing similar arrangements with other hospitals throughout the Northeast.

      By acquiring private practices - either occupational  medicine or physical
therapy  practices - OH+R can enter a new  geographical  area or consolidate its
position within an existing market.  Therapy  practices  receive  referrals from
local  physicians  which can  complement  OH+R's direct  marketing to employers.
Alternatively,  occupational  medicine practices have established  relationships
with employers to whom OH+R's more comprehensive services may be provided.


                                     103

      Many group health insurers and health maintenance organizations (HMOs) are
developing  or  attempting  to develop  products for the  workers'  compensation
market. These offerings include development and management of preferred provider
organizations (PPOs),  claims  administration  services and owning and operating
occupational healthcare centers similar to OH+R's.

      Health  insurers  are  interested  in  occupational  health  and  workers'
compensation for several reasons:

     o    Experimental  "24 Hour  Coverage  Programs"  have been  authorized  by
          several  states.  These programs  combine  general health and workers'
          compensation  insurance in an effort to  streamline  the insurance and
          reimbursement systems and eliminate duplicate costs.

     o    High quality  occupational health providers have extensive  experience
          in  minimizing  the impact of  disabling  injuries  and  illnesses  on
          patients.  Health  insurers are  increasingly  interested in utilizing
          this  expertise  for  non-occupational   patients  with  injuries  and
          illnesses requiring disability management.

     o    Incremental revenues from the sale of workers'  compensation  products
          to current clients.

     o    Leverage of perceived  operational  competencies in claims  processing
          and provider relations.

      OH+R  offers  health   insurers/HMOs   the  ability  to  quickly  offer  a
state-of-the-art  program  for the  prevention,  treatment,  and  management  of
work-related  injuries. For staff model HMOs or group health insurers with owned
medical  practices  and  outpatient  centers,  OH+R would  intend to develop and
operate occupational healthcare programs either in existing outpatient treatment
centers or stand-alone centers. For independent  practitioner  associations HMOs
(IPAs),  or group health insurers not owning healthcare  facilities,  OH+R could
either establish occupational healthcare centers or develop and manage preferred
provider networks which utilize OH+R's proprietary system.

      OH+R will also consider  establishing  start-up centers.  This approach is
most suitable for  geographic  areas  proximate to existing OH+R centers and for
later  stages  in  OH+R's  development  when its  "brand  name"  is more  widely
recognized.  This approach may also be suitable where a large source of patients
can be  assured  through  arrangements  with  large  employers  and third  party
administrators or where competition is limited.

Competition

      Most organizations  providing care for work-related injuries and illnesses
are local providers or hospitals.  The fundamental  difference  between OH+R and
these providers is OH+R's focus on combining multiple disciplines to address the
needs of a single market

                                     104

<PAGE>



segment --  work-related  injuries and illnesses.  Other providers are generally
organized  to provide  services,  such as therapy,  to a wide  variety of market
segments with differing needs  regardless of the source of the injury or type of
patient or injury.

      The vast majority of OH+R's competitors are local operations and typically
provide only some of the services required to successfully  resolve work-related
injuries and  illnesses.  Those that do provide  most of the  required  services
(i.e., some hospitals) do not do so as part of a tightly integrated, formal care
system.  Injured  workers tend to be a small segment of the patients seen by the
individual  departments  involved.  Department  personnel  tend  not to have any
particular training or expertise in work-related injuries and illnesses.

      At the  present  time,  OH+R is aware of no national  occupational  health
providers  and only a few  regional  occupational  health  providers,  including
OccuSystems,  Inc.,  whose  activities  are primarily in the South,  Midwest and
Mid-Atlantic  states,  and Atlantic  Health  Group,  a member of Liberty  Mutual
Group, whose activities are in the Northeast, South and Mid-Atlantic states.

Laws and Regulations

      General

      As a  participant  in  the  healthcare  industry,  OH+R's  operations  and
relationships are subject to extensive and increasing  regulation by a number of
governmental  entities  at the  federal,  state and local  levels.  OH+R is also
subject to laws and  regulations  relating to business  corporations in general.
OH+R believes that its operations  are in material  compliance  with  applicable
laws.  Nevertheless,  because of the special nature of OH+R's  relationship with
the  professional  corporations  and satellite  clinics,  many aspects of OH+R's
business  operations  have not been the  subject of state or federal  regulatory
interpretation,  and  there can be no  assurance  that a review of OH+R's or the
professional   corporations  and  satellite   clinics'  business  by  courts  or
regulatory  authorities will not result in a determination  that could adversely
affect the  operations of OH+R or the  professional  corporations  and satellite
clinics or that the healthcare  regulatory  environment will not change so as to
restrict OH+R's or the professional corporations and satellite clinics' existing
operations or their expansion. See "RISK FACTORS."

      Workers' Compensation Legislation

      The  federal  government  and  each  state  in which  OH+R  does  business
administer  workers'  compensation  programs,  which require  employers to cover
medical  expenses,  lost  wages  and other  costs  resulting  from  work-related
injuries,  illnesses  and  disabilities.  Medical  costs are paid to  healthcare
providers  through the employers'  purchase of insurance  from private  workers'
compensation  carriers,  participation  in a state  fund  or by  self-insurance.
Changes in workers'  compensation  laws or  regulations  may create a greater or
lesser demand for some or all of OH+R's services, require OH+R to develop new or
modified services to meet the needs

                                     105

<PAGE>



of the  marketplace  and  compete  effectively  or modify the fees that OH+R may
charge for its services.

      Many states are  considering or have enacted  legislation  reforming their
workers'  compensation  laws.  These reforms  generally give  employers  greater
control over who will provide  medical care to their  employees  and where those
services will be provided,  and attempt to contain medical costs associated with
workers'  compensation  claims. Some states have implemented  diagnosis-specific
fee schedules that set maximum reimbursement levels for healthcare services. The
federal government and certain states provide for a  "reasonableness"  review of
medical costs paid or reimbursed by workers' compensation.  When not governed by
a fee  schedule,  OH+R  adjusts  its charges to the usual and  customary  levels
authorized by the payor.

      Corporate Practice of Medicine and Other Laws

      Most states  limit the  practice of  medicine to licensed  individuals  or
professional  organizations comprised of licensed individuals.  Many states also
limit the scope of business relationships between business entities such as OH+R
and licensed  professionals  and professional  corporations,  particularly  with
respect to  fee-splitting  between a physician and another  person or entity and
non-physicians  exercising  control over  physicians  engaged in the practice of
medicine.

      Laws and regulations  relating to the practice of medicine,  fee-splitting
and similar  issues  vary  widely  from state to state,  are often vague and are
seldom  interpreted  by courts or regulatory  agencies in a manner that provides
guidance  with respect to business  operations  such as those of OH+R.  Although
OH+R  attempts to structure  all of its  operations so that they comply with the
relevant state statutes and believes that its operations and planned  activities
do not violate any applicable  medical  practice,  fee-splitting or similar law,
there can be no assurance  that (i) courts or  governmental  officials  with the
power to interpret or enforce  these laws and  regulations  will not assert that
OH+R or certain  transactions  in which it is involved  are in violation of such
laws  and  regulations  and  (ii)  future   interpretations  of  such  laws  and
regulations  will not require  structural and  organizational  modifications  of
OH+R's  business.  In addition,  the laws and  regulations  of some states could
restrict expansion of OH+R's operations into those states.

      Fraud and Abuse Laws

      A federal law (the "Anti-Kickback  Statute") prohibits any offer, payment,
solicitation  or receipt of any form of  remuneration to induce or in return for
the  referral of  Medicare  or state  health  program  patients or patient  care
opportunities,  or in  return  for the  purchase,  lease  or  order  of items or
services  that are covered by Medicare or state health  programs.  Violations of
the statute  can result in the  imposition  of  substantial  civil and  criminal
penalties. In addition, as of January 1, 1995, certain anti-referral  provisions
(the "Stark Amendments")  prohibit a physician with a "financial interest" in an
entity from referring a patient to that entity for the

                                     106

<PAGE>



provision of certain  "designated  medical services" (some of which are provided
by the  professional  corporations  and  satellite  clinics  that engage  OH+R's
management services).

      Most states have statutes, regulations or professional codes that restrict
a physician from accepting  various kinds of remuneration in exchange for making
referrals.  Several  states are  considering  legislation  that  would  prohibit
referrals  by a physician  to an entity in which the  physician  has a specified
financial interest.

      All of the foregoing laws are subject to modification and  interpretation,
have not often been interpreted by appropriate  authorities in a manner directly
relevant to OH+R's  business and are enforced by  authorities  vested with broad
discretion.  OH+R has attempted to structure all of its  operations so that they
comply with all applicable federal and state  anti-referral  prohibitions.  OH+R
also  continually  monitors  developments  in  this  area.  If  these  laws  are
interpreted  in a manner  contrary to OH+R's  interpretation,  reinterpreted  or
amended,  or if new legislation is enacted with respect to healthcare  fraud and
abuse or similar issues,  OH+R will seek to restructure any affected  operations
so as to maintain compliance with applicable law. No assurance can be given that
such restructuring will be possible, or, if possible,  will not adversely affect
OH+R's business.

      Uncertainties Related to Changing Healthcare Environment

      Since early 1993, the healthcare industry has experienced change. Although
managed care has yet to become a major factor in occupational  healthcare,  OH+R
anticipates that managed care programs,  including capitation plans, may play an
increasing  role  in the  delivery  of  occupational  healthcare  services,  and
competition in the  occupational  healthcare  industry may shift from individual
practitioners  to  specialized  provider  groups such as those  managed by OH+R,
insurance  companies,   health  maintenance  organizations  ("HMOs")  and  other
significant  providers of managed care  products.  To facilitate  OH+R's managed
care  strategy,   OH+R  is  offering  risk-sharing  products  for  the  workers'
compensation  industry that will be marketed to employers,  insurers and managed
care  organizations.  No  assurance  can be given that OH+R will  prosper in the
changing healthcare  environment or that OH+R's strategy to develop managed care
programs will succeed in meeting employers' and workers' occupational healthcare
needs.

      Environmental

      OH+R  is  subject  to  various  federal,  state  and  local  statutes  and
ordinances  regulating the disposal of infectious  waste.  If any  environmental
regulatory  agency  finds  OH+R's  facilities  to be in violation of waste laws,
penalties and fines may be imposed for each day of  violation,  and the affected
facility  could be  forced to cease  operations.  OH+R  believes  that its waste
handling and discharge practices are in material compliance with applicable law.

Important Factors Regarding Forward-Looking Statements

      This section entitled  "INFORMATION  ABOUT OH+R" contains  forward-looking
statements  within the meaning of Section 27A of the  Securities Act and Section
21E of the  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  OH+R's  objective  to  develop  a  comprehensive
regional  network  of  occupational   healthcare  centers  providing  integrated
services through  multi-disciplinary  teams.  Among the risks and  uncertainties
that will affect OH+R's actual  results in achieving this objective are locating
and  identifying  suitable  acquisition  candidates,  the ability to  consummate
acquisitions on favorable terms, the success of such acquisitions, if completed,
the costs and delays  inherent  in managing  growth,  the ability to attract and
retain  qualified  professionals  and other  employees to expand and  compliment
OH+R's services, the availability of sufficient financing and the attractiveness
of the Surviving Corporation's capital stock to finance acquisitions, strategies
pursued by competitors,  the restrictions imposed by government regulation,  and
changes in the industry resulting from changes in workers' compensation laws and
regulations  and  in  the  healthcare  environment  generally.  See  also  "RISK
FACTORS."

Employees

      As of December 31, 1995, OH+R employed a total of 112 individuals. None of
OH+R's employees are covered by collective bargaining  agreements.  OH+R has not
experienced any work stoppages and considers its relations with its employees to
be good.

Litigation

      OH+R is not a party to any  material  litigation  and is not  aware of any
pending or threatened  litigation that could have a material adverse effect upon
its business, operating results or financial condition.

Facilities

      OH+R leases its  principal  offices in Hingham,  Massachusetts.  OH+R also
leases the facilities housing its centers (other than the Waltham Center),  with
the lease for the Boston Center being subleased to New England Baptist Hospital,
in connection with the joint venture that OH+R established with NEB Enterprises,
Inc., an affiliate of the hospital.

OH+R's  Management's  Discussion and Analysis of Financial Condition and Results
of Operations

      Overview.

      OH+R was  organized  in 1992 to  develop a network of  outpatient  centers
throughout the Northeast.  OH+R derives patient  service revenue  primarily from
the prevention, treatment and management of work-related injuries and illnesses.
In the years ended  December 31,  1993,  1994,  and 1995,  total  revenues  were
approximately $1,738,000, $2,692,000, and $6,024,000, respectively.

      OH+R's  operations  have been funded  primarily  through  venture  capital
investments.   OH+R's  growth  has  resulted  primarily  from  acquisitions  and
development of businesses principally engaged in occupational healthcare.

      The following table sets forth,  for the periods  indicated,  the relative
percentages which certain items in OH+R's  consolidated  statements of operation
bear to total revenue.

                                                  Year Ended December 31,
                                              -----------------------------

      Years Ended December 31, 1995, 1994 and 1993

      Revenue.  Total  revenue  increased  123.8%  to  $6,024,000  in 1995  from
$2,692,000 in 1994, and increased  54.9% in 1994 from $1,738,000 in 1993. Of the
$3,332,000  increase  from  1994 to 1995,  $1,159,000  resulted  from  practices
acquired and developed in 1994,  $1,776,000  resulted from practices acquired in
1995,  $293,000 resulted from increased  business in markets where OH+R operated
centers  during  the  entire  months of both years and  $104,000  resulted  from
increases in management  agreements to operate outpatient healthcare centers. Of
the  $954,000  increase  from  1993 to  1994,  $539,000  resulted  from a center
developed in 1993,  $142,000  resulted from practices  acquired and developed in
1994 and  $273,000  resulted  from  increased  business  in  markets  where OH+R
operated centers during the entire months of both years.

      Operating  and  Administrative  expenses.   Operating  and  administrative
expenses  increased  99.2% to  $7,698,000  in 1995 from  $3,865,000  in 1994 and
increased  27.0%  in  1994  from  $3,043,000  in  1993.   These  increases  were
principally due to the  acquisition and development of additional  practices and
the increase of OH+R's corporate staff to the level necessary for the management
of the  growing  business.  As a  percentage  of total  revenue,  operating  and
administrative  expenses  decreased from 175.1% in 1993 to 143.6% in 1994 and to
127.8% in 1995. OH+R believes that as the additional  contemplated  acquisitions
are completed following the Merger, if approved,  further leveraging of existing
management will occur and, as a result,  operating and  administrative  expenses
will further decline as a percentage of total revenue.

      Depreciation  and  Amortization.  Depreciation  and  amortization  expense
increased  64.4% to $365,000 in 1995 from $222,000 in 1994 and 1.0% in 1994 from
$220,000 in 1993. These increases were incurred  primarily as a result of OH+R's
additional growth through center development and acquisitions.

      Interest Expense. Interest expense increased 83.0% to $97,000 in 1995 from
$53,000 in 1994 and decreased in 1994 by 5.4% from $56,000 in 1993. The increase
from 1994 to 1995 was due to the incurrence of certain debt as consideration for
several  acquisitions.   Additionally,   in  1995,  OH+R  sold  certain  medical
receivables  to provide  operating  cash and to pay down  certain term loans and
notes  payable.  The decrease from 1993 to 1994 resulted from the  retirement of
certain  long-term debt assumed in connection with a practice  acquired in 1992.
As a percentage of total  revenue,  interest  expense was 1.6% in 1995,  2.0% in
1994, and 3.2% in 1993.


                                     114

<PAGE>



      Interest Income. Interest income is generated primarily from cash invested
in highly liquid funds with a maturity of three months or less.  Interest income
remained  unchanged in 1995 and decreased  11.6% to $38,000 in 1994 from $43,000
in 1993.  The decrease in interest  income from 1993 to 1994 resulted from a net
use of approximately $436,000 in cash during 1994.

      Minority Interest.  Minority interest  represents NEB Enterprises,  Inc.'s
49% share of the losses incurred by NEB  Occupational  Health from April 1, 1995
(inception) through December 31, 1995.

      Events Since December 31, 1995. No material trends, events or transactions
have arisen  since  December  31,  1995,  that would  materially  affect  OH+R's
financial condition or results of operations.

      Liquidity and Capital Resources

      Since  inception,  OH+R'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 sale of a minority  interest in NEB
Occupational Health. Net proceeds from the sale of OH+R Preferred Stock and OH+R
Common Stock have totalled  approximately  $5.5 million.  In addition,  OH+R has
received  approximately  $1.4 million in debt and other  long-term  commitments.
During 1995, OH+R received  approximately  $1.8 million from the sale of certain
accounts receivable.

      Net cash used in operating activities by OH+R was approximately  $795,000,
$1,232,000,  and $1,403,000 in 1995, 1994 and 1993, respectively.  The principal
use of  cash  was  to  fund  OH+R's  operating  losses  in its  early  stage  of
development.  These operating losses were offset by non-cash  expenses,  such as
depreciation  and  amortization  and by  fluctuations  in working capital during
those periods.  Working capital  fluctuations have been primarily from increases
in accounts  receivable and other current assets offset by increases in accounts
payable and accrued expenses.

      OH+R's investing  activities  included  capital  expenditures of $162,000,
$73,000  and  $234,000 in 1995,  1994 and 1993,  respectively.  Other  investing
activities  included cash paid for  acquisitions of $336,000 and $41,000 in 1995
and 1994, respectively.  Since inception,  OH+R has received equipment financing
of  approximately  $421,000  through capital  leases.  Payments on capital lease
obligations were approximately $101,000,  $48,000, and $49,000 in 1995, 1994 and
1993,  respectively.  OH+R also received a partnership  capital  contribution of
cash in the amount of $196,000 from NEB Enterprises, Inc.

      OH+R expects that its principal use of funds in the near future will be in
connection with acquisitions,  working capital requirements, debt repayments and
purchases of property  and  equipment.  OH+R expects that Telor's cash  balances
(assuming the Merger is consummated), cash generated from operations,  available
lines of credit and sales of certain  accounts  receivable  will be  adequate to
satisfy OH+R's cash requirements through 1996. However,  OH+R believes the level
of financial  resources  available to it is an important  competitive factor and
may seek additional  financing  prior to the end of that period.  OH+R considers
raising  additional capital on an on-going basis as market factors and its needs
suggest. In addition, if the Merger is not consummated in a timely fashion, OH+R
will need to obtain other sources of funds to finance  on-going  operations  and
its expansion plans.

                     DESCRIPTION OF CAPITAL STOCK OF TELOR

Common Stock

      Telor.  Telor's  Certificate  of  Incorporation  currently  authorizes the
issuance of 25,000,000  shares of common stock, par value $.001 per share. As of
April 15, 1996,  there were 786,192 shares of Telor Stock issued and outstanding
and  no  shares  held  in  the  corporate  treasury.  In  addition,  there  were
outstanding  options  under Telor's stock option plans to purchase an additional
46,700  shares of Telor Stock,  and 119,574  shares of Telor Stock were reserved
for future option grants under such plans. Upon effectiveness of the Merger, the
number of shares of Telor Stock reserved for future option grants under the 1988
Plan will be reduced by 16,099.  If Proposal 2 is adopted,  the number of shares
issuable  under the 1993 Plan will be  increased by 105,000 and if Proposal 3 is
adopted,  Telor's  Certificate of  Incorporation  will authorize the issuance of
10,000,000  shares of Common  Stock,  par value  $.001 per share,  a decrease of
15,000,000 shares.

      Subject  to the rights of holders  of  preferred  stock,  holders of Telor
Stock are entitled to participate equally in dividends,  when and as declared by
the Board of  Directors,  out of funds  legally  available  therefor and, in the
event of liquidation or distribution  of assets of Telor,  are entitled to share
ratably  in  such  assets   remaining  after  payment  of   liabilities.   Telor
stockholders are entitled to one vote per share.  Holders of Telor Stock have no
conversion, preemptive or other subscription rights, and there are no redemption
or sinking fund provisions with respect to such stock. The outstanding shares of
Telor Stock are fully paid and nonassessable.

Business Combination Provision

      Telor's  Certificate of Incorporation  restricts  "business  combinations"
with  "interested   stockholders,"  as  such  terms  are  described  in  Telor's
Certificate  of  Incorporation  (the  "Business  Combination  Provision").   The
Business  Combination   Provision  provides  that  business   combinations  with
interested  stockholders (without regard to the length of time a stockholder has
been an  interested  stockholder)  may not be  consummated  without  the vote of
holders of 70% of all outstanding  shares of Telor voting stock entitled to vote
in the  election  of  directors,  voting  together  as one  class.  A  "business
combination"  for  purposes  of  the  application  of the  Business  Combination
Provision  includes  (i) a  merger  or  consolidation,  (ii)  the  sale or other
disposition of 10% or more of the fair market value of Telor's assets, (iii) the
issuance of stock  having a value in excess of 10% of the fair  market  value of
the outstanding shares of Telor voting stock entitled to vote in the election of
directors, (iv) the adoption of a plan of liquidation or dissolution proposed by
or on  behalf  of an  interested  stockholder  and (v) any  reclassification  or
recapitalization   which  increases  the   proportionate   shareholdings  of  an
interested  stockholder  (except  certain  immaterial  changes).  An "interested
stockholder"  for  purposes  of  the  application  of the  Business  Combination
Provision  includes any person or entity who is (or who is an affiliate of Telor
and during the prior two years was) the beneficial owner of more than 15% of the
voting stock of Telor.


                                     117

<PAGE>



      The provisions of the Telor's  Certificate of  Incorporation  described in
the preceding  paragraph may be amended or repealed only by the affirmative vote
of 70% of the shares entitled to vote thereon.

      The effect of the foregoing  provisions is to make it more difficult for a
person,  entity or group to  effect a change in  control  of Telor  through  the
acquisition of a large block of Telor's  voting stock,  or to effect a merger or
other  acquisition  that is not approved by a majority of Telor's  directors who
were serving in office prior to the  acquisition by the other person,  entity or
group of 5% or more of Telor's stock (or who subsequently  became directors with
the approval of such  directors)  and who are not  affiliated  with such person,
entity or group.

Section 203 of the DGCL

      Telor is subject to the provisions of Section 203 of the Delaware  General
Corporation Law (the "DGCL").  That section provides,  with certain  exceptions,
that a Delaware  corporation  may not engage in any of a broad range of business
combinations  with a person or  affiliate  or associate of such person who is an
"interested  stockholder"  for a period of three  years  from the date that such
person became an interested stockholder unless: (i) the transaction resulting in
a person's becoming an interested stockholder,  or the business combination,  is
approved by the board of directors of the corporation  before the person becomes
an interested stockholder,  (ii) the interested stockholder acquires 85% or more
of the outstanding  voting stock of the corporation in the same transaction that
makes it an interested stockholder (excluding shares held by directors, officers
and certain employee stock ownership  plans);  or (iii) on or after the date the
person becomes an interested  stockholder,  the business combination is approved
by the corporation's board of directors and by the holders of at least 662/3% of
the  corporation's  outstanding  voting  stock at an annual or special  meeting,
excluding   shares  owned  by  the   interested   stockholder.   An  "interested
stockholder" is defined to include any person, and the affiliates and associates
of such  person that (i) is the owner of 15% or more of the  outstanding  voting
stock of the corporation or (ii) is an affiliate or associate of the corporation
and  was  the  owner  of 15% or  more of the  outstanding  voting  stock  of the
corporation at any time within the three-year  period  immediately  prior to the
date on which it is sought to be determined whether such person is an interested
stockholder.  It is  anticipated  that the provisions of Section 203 of the DGCL
may encourage  companies or others interested in acquiring Telor to negotiate in
advance  with the  Telor  Board of  Directors,  since the  stockholder  approval
requirement  would be  avoided  if a majority  of the  directors  then in office
approve either the business  combination or the transaction which results in the
acquiror becoming an interested stockholder.

Preferred Stock

      Telor's  Certificate  of  Incorporation  authorizes  the issuance of up to
5,000,000  shares of  preferred  stock,  par value  $.001 per share (the  "Telor
Preferred  Stock").  The Board of Directors has the authority to issue the Telor
Preferred  Stock  in one or  more  series  and to fix the  rights,  preferences,
privileges  and  restrictions,  including the dividend  rights,  dividend  rate,
conversion  rights,  voting  rights,  terms of redemption,  redemption  price or
prices, liquidation preferences and the number of shares constituting any series
or the designations of such series,

                                     118

<PAGE>



without any further  vote or action by the  stockholders.  Issuance of shares of
Telor Preferred Stock,  while providing  flexibility in connection with possible
acquisitions  and other corporate  purposes,  could have the effect of making it
more  difficult for a third party to acquire,  or of  discouraging a third party
from acquiring,  a majority of the outstanding  voting stock of Telor.  Any such
issuance  could also  adversely  affect the voting power of the holders of Telor
Stock.  The Board of Directors of Telor has no current  intention of issuing any
shares of Telor Preferred Stock.  However, if the Merger is consummated,  shares
of Preferred Stock would likely be issued in connection with the expansion plans
of the Surviving Corporation.

Transfer Agent

      The transfer  agent and registrar for the Telor Stock is State Street Bank
and Trust Company.

              COMPARISON OF RIGHTS OF TELOR AND OH+R STOCKHOLDERS

      Both Telor and OH+R are  incorporated in Delaware.  Therefore,  holders of
OH+R Common Stock and OH+R  Preferred  Stock will  continue to have their rights
and  obligations as  stockholders of Telor after the Merger governed by Delaware
law.  Set  forth  below  is a  summary  comparison  of  the  rights  of a  Telor
stockholder  under Telor's  Certificate of  Incorporation  and Telor's  Restated
By-laws  (the  "Telor  By-laws"),  on the one  hand,  and the  rights of an OH+R
stockholder under OH+R's Certificate of Incorporation  (the "OH+R  Certificate")
and By-laws (the "OH+R  By-laws"),  on the other hand. The information set forth
below is  qualified  in its  entirety by  reference  to Telor's  Certificate  of
Incorporation, the Telor By-laws, the OH+R Certificate and the OH+R By-laws.

Classes and Series of Capital Stock

      Telor.  Telor's  Certificate  of  Incorporation  currently  authorizes the
issuance of up to 30,000,000 shares of capital stock, of which 25,000,000 shares
are designated common stock, par value $.001 per share, and 5,000,000 shares are
designated  preferred  stock,  par value $.001 per share.  As of April 15, 1996,
there were 786,192  shares of Telor Stock issued and  outstanding  and no shares
held in the corporate  treasury.  In addition,  there were  outstanding  options
under  Telor's  stock option plans to purchase an  additional  46,700  shares of
Telor Stock,  and 133,361  shares of Telor Stock are reserved for future  option
grants under such plans. Upon  effectiveness of the Merger, the number of shares
of Telor Stock  reserved  for future  option  grants under the 1988 Plan will be
reduced by 16,099. If Proposal 2 is adopted, the number of shares issuable under
the 1993 Plan will be increased by 105,000 and if Proposal 3 is adopted, Telor's
Certificate of Incorporation will authorize the issuance of 10,000,000 shares of
Common  Stock  and  5,000,000  shares  of Telor  Preferred  Stock.  The Board of
Directors of Telor has the authority to issue the Telor  Preferred  Stock in one
or  more  series,  and to fix  the  designation,  powers,  preferences,  rights,
qualifications,  limitations or  restrictions  of each such series,  without any
further vote or action by its stockholders.  As of April 15, 1996, there were no
shares  of Telor  Preferred  Stock  issued  and  outstanding,  and the  Board of
Directors of Telor has no present intention of issuing shares of Telor Preferred
Stock.  However,  if the Merger is consummated,  shares of Preferred Stock would
likely  be  issued  in  connection  with the  expansion  plans of the  Surviving
Corporation.

      OH+R. OH+R is authorized by the OH+R  Certificate to issue up to 8,000,000
shares of common  stock,  par value $.01 per share (the  "OH+R  Common  Stock"),
1,600,000  shares of Series 1  preferred  stock,  par value $.01 per share,  and
3,000,000  shares of Series 2  preferred  stock,  par value $.01 per share.  The
Series 1 preferred stock and the Series 2 preferred stock are referred to as the
"OH+R Preferred  Stock." As of April 15, 1996, there were 674,605 shares of OH+R
Common  Stock  issued and  outstanding,  1,600,000  shares of Series 1 preferred
stock  issued and  outstanding,  2,537,843  shares of Series 2  preferred  stock
issued  and  outstanding  and no  shares  held  in the  corporate  treasury.  In
addition,  there were outstanding options under OH+R's stock plan to purchase an
additional 844,963 shares of OH+R Common Stock, and 23,238 shares of OH+R Common
Stock are reserved for future option grants under such plan.

Size and Election of the Board of Directors

      Telor.  Telor's Certificate of Incorporation and the Telor By-laws provide
that the size of the Telor Board of  Directors  shall be fixed from time to time
by the directors then in office.  Telor's Board of Directors is classified  into
three classes. Each director is elected for a three year term, with one class of
directors  being elected at each annual  meeting of  stockholders.  Directors of
Telor  are  elected  by a  plurality  of votes  cast at the  annual  meeting  of
stockholders.   Vacancies   on  the  Board  of  Directors   and  newly   created
directorships  resulting from any increase in the authorized number of directors
are  filled by a  majority  vote of the  directors  then in  office.  Before the
Effective Time of the Merger,  certain holders of Telor Stock and certain of the
OH+R  Securityholders  shall  have  entered  into a written  agreement  to elect
certain  specified  individuals  to the  Board  of  Directors  of the  Surviving
Corporation at the 1996 annual meeting of the stockholders.

      OH+R.  OH+R's By-laws provide that the size of the OH+R Board of Directors
shall be fixed from time to time by resolutions of either the Board of Directors
or the stockholders in accordance with applicable law (each being subject to any
subsequent resolutions of either of them). Each director shall hold office until
the  director's  successor  has been duly  elected  and  qualified  or until the
director's earlier death, resignation or removal.  Directors of OH+R are elected
by a  plurality  of votes cast at the meeting  for the  election  of  directors.
Vacancies on the Board of Directors  and newly created  directorships  resulting
from any increase in the authorized number of directors are filled by a majority
vote of the directors  then in office.  OH+R  currently has agreements in effect
pursuant  to which  the  number  of  directors  shall  not  exceed  five and the
stockholders have agreed to vote in favor of certain director  designees.  These
agreements would be terminated as part of the Merger.

Removal of Directors

      Telor. Telor's Certificate of Incorporation provides that directors may be
removed,  with or without cause,  by the  affirmative  vote of the holders of at
least 70% of the voting power of the then outstanding shares of capital stock of
Telor, voting together as a single class.

      OH+R.  OH+R's  By-laws  provide that  directors may be removed from office
with or  without  cause at any  meeting  of  stockholders  duly  called,  by the
affirmative vote of a majority of the shares present in person or represented by
proxy.

Other Voting Rights

      Telor. Telor's Certificate of Incorporation authorizes Telor to issue both
Telor Stock and Telor Preferred Stock. Telor has no classes or series of capital
stock  issued or  outstanding  other than Telor  Stock.  Each Telor  stockholder
holding shares of Telor Stock entitled to be voted on any matter,  including the
election of directors, shall have one vote on each matter submitted to a vote at
a meeting of stockholders for each share of Telor Stock held by such stockholder
as of the  record  date  for  such  meeting.  Except  as  specifically  provided
otherwise  by  law or by  Telor's  Certificate  of  Incorporation  or the  Telor
By-laws, the vote of the holders of a majority

                                     121

<PAGE>



of the shares of capital  stock present or  represented  and entitled to vote is
required for the approval of any matter at a meeting of Telor stockholders.  The
affirmative  vote of holders of at least 70% of the outstanding  voting stock of
Telor is required to amend or repeal the Telor By-laws and certain provisions of
Telor's Certificate of Incorporation, to approve certain "business combinations"
(as  described  below) and to reduce the  number of  authorized  shares of Telor
Stock and Telor Preferred Stock.

      OH+R.  OH+R's By-laws provide that unless  otherwise  provided in the OH+R
Certificate or required by law, each OH+R  stockholder  shall be entitled to one
vote  for  each  share  of  capital  stock  held by such  stockholder  which  is
registered  in such  stockholder's  name on the  record  date  for the  meeting.
Pursuant to OH+R's Certificate, each share of OH+R Preferred Stock shall entitle
the holder  thereof to such  number of votes per share as shall equal the number
of shares of OH+R Common Stock into which each share of OH+R Preferred  Stock is
then convertible,  and each such holder shall be entitled to vote on all matters
as to which  holders of OH+R's  Common  Stock shall be entitled to vote,  voting
together  with the holders of the OH+R Common  Stock as one class.  In all cases
where the holders of OH+R Preferred Stock have the right to vote separately as a
class, in addition to the voting rights  described above, all such holders shall
be entitled to one vote for each share held by them.  Unless otherwise  provided
in the OH+R Certificate,  directors shall be elected by a plurality of the votes
of the  shares  present in person or  represented  by proxy at the  meeting  and
entitled to vote on the election of directors.  Except as otherwise  provided in
OH+R's  Certificate or by law, in all other matters,  the affirmative  vote of a
majority of the shares  present in person or represented by proxy at the meeting
and  entitled  to vote  on the  subject  matter  shall  be the  act of the  OH+R
stockholders.  Voting, including voting for the election of directors,  need not
be by written ballot.  OH+R's  Certificate  requires the affirmative  consent or
approval of the holders of shares representing at least two-thirds of the voting
power of the OH+R  Preferred  Stock then  outstanding,  acting  separately  as a
class,  to approve  certain  fundamental  changes,  including the declaration or
payment  of  dividends,  certain  redemptions  of  stock,  changes  to the  OH+R
Certificate adversely affecting the Preferred Stock, mergers,  consolidations or
sales of all or substantially all of OH+R's assets and dissolution of OH+R.

Dividends

      Telor.  Telor's Certificate of Incorporation grants the Board of Directors
the  power to  distribute  to  holders  of Telor  Stock,  without  a vote of the
stockholders,  dividends,  whether  payable in cash,  property or  securities of
Telor, out of funds lawfully available therefor.  If the Board of Directors were
to  designate  a series of Telor  Preferred  Stock,  the  holders  of such Telor
Preferred Stock could be entitled to dividend  payments  preferential to holders
of Telor Stock.

      OH+R. Pursuant to OH+R's  Certificate,  holders of OH+R Common Stock shall
be entitled to  dividends  ratably  with all other  shares of OH+R Common  Stock
outstanding when, if and as such dividends are declared and paid by the Board od
Directors,  subject to the prior dividend  rights of the OH+R  Preferred  Stock.
OH+R's Certificate  requires the affirmative  consent or approval of the holders
of shares  representing  at least  two-thirds  of the  voting  power of the OH+R
Preferred Stock then outstanding, acting separately as a class, to approve the

                                     122

<PAGE>



declaration or payment of dividends  with respect to the OH+R Common Stock.  The
OH+R Preferred Stock is entitled to cumulative  dividends,  as more particularly
described  in the  financial  statements  of  OH+R  included  elsewhere  in this
Offering Memorandum/Proxy Statement.

Conversion and Dissolution

      Telor. Telor's Certificate of Incorporation authorizes 5,000,000 shares of
Telor  Preferred  Stock,  and  provides  that such  shares may have such  voting
powers, preferences and other special rights (including, without limitation, the
right to convert the shares of such Telor  Preferred  Stock into shares of Telor
Stock)  as shall be  stated  in a  Certificate  of  Designation  or  resolutions
providing for the issuance of Telor  Preferred  Stock. If the Board of Directors
were to designate such a series of Telor Preferred  Stock,  such Telor Preferred
Stock could be entitled to preferential  payments in the event of a liquidation,
dissolution or winding up of Telor.

      OH+R. The OH+R Preferred Stock is convertible  into OH+R Common Stock on a
one-for-one  basis,  subject  to  certain  anti-dilution  provisions.  The  OH+R
Preferred  Stock  is  entitled  to  preferential  payments  in  the  event  of a
liquidation,  distribution of assets, dissolution or winding up of OH+R, as more
particularly described in the financial statements of OH+R included elsewhere in
this Offering Memorandum/Proxy Statement.

Business Combination Provision

      Telor.   Telor's  Certificate  of  Incorporation   contains  the  Business
Combination   Provision.   The  Business  Combination  Provision  provides  that
"business  combinations" with "interested  stockholders"  (without regard to the
length of time a  stockholder  has been an  interested  stockholder)  may not be
consummated  without  the vote of  holders of 70% of all  outstanding  shares of
Telor  voting  stock  entitled  to vote in the  election  of  directors,  voting
together as one class. A "business  combination" for purposes of the application
of the Business  Combination  Provision  includes (i) a merger or consolidation,
(ii) the sale or other  disposition  of 10% or more of the fair market  value of
Telor's  assets,  (iii) the issuance of stock having a value in excess of 10% of
the fair market value of the  outstanding  shares of Telor voting stock entitled
to vote in the election of directors, (iv) the adoption of a plan of liquidation
or dissolution proposed by or on behalf of an interested stockholder and (v) any
reclassification   or   recapitalization   which  increases  the   proportionate
shareholdings of an interested  stockholder (except certain immaterial changes).
An  "interested  stockholder"  for purposes of the  application  of the Business
Combination  Provision  includes  any  person  or  entity  who is (or  who is an
affiliate of Telor and during the prior two years was) the  beneficial  owner of
more than 15% of the voting stock of Telor. See "DESCRIPTION OF CAPITAL STOCK OF
TELOR Business Combination Provision."

      OH+R. The OH+R Certificate contains no provisions similar to the "business
combination" provisions of Telor's Certificate of Incorporation set forth above.

Amendment of the Certificate of Incorporation

      Under Delaware law,  unless its  certificate of  incorporation  or by-laws
otherwise  provide,  amendments of a corporation's  certificate of incorporation
generally require the approval of holders of a majority of the outstanding stock
entitled to vote thereon,  and if such amendment  would increase or decrease the
authorized  shares of any  class or  series  or the par value of such  shares or
would  adversely  affect the shares of such class or series,  the  approval of a
majority of the outstanding shares of such class or series.

      Telor.  Telor's Certificate of Incorporation  requires approval of holders
of at least 70% of the  outstanding  shares  entitled to vote  generally  in the
election  of  directors,  voting  together as a single  class:  (i) to reduce or
eliminate  the  number  of  authorized  shares of Telor  Stock or the  number of
authorized shares of Telor Preferred Stock and (ii) to amend or repeal, or adopt
any provision inconsistent with, the following provisions of Telor's Certificate
of  Incorporation:  Section C of Article FOURTH  (regarding the Telor  Preferred
Stock),  Article FIFTH (regarding the management of the business and the conduct
of the  affairs of Telor,  including  the  calling of  special  meetings  by the
stockholders),  Article SIXTH (regarding the election and removal of directors),
Article  SEVENTH  (regarding  the  adoption,  amendment  or  repeal of the Telor
Bylaws),  Article  EIGHTH  (regarding  the  "business  combination"  provision),
Article NINTH (regarding indemnification of directors), Article TENTH (regarding
the liability of directors)  and Article  ELEVENTH  (regarding  the amendment or
repeal of provisions of Telor's Certificate of Incorporation).

      OH+R. OH+R's Certificate  requires the affirmative  consent or approval of
the holders of shares  representing  at least  two-thirds of the voting power of
the OH+R Preferred  Stock then  outstanding,  acting  separately as a class,  to
approve changes to the OH+R Certificate  adversely  affecting the OH+R Preferred
Stock.

Special Meeting of Stockholders

      Telor.  Telor's Certificate of Incorporation and the Telor By-laws provide
that a special  meeting  of the  Telor  stockholders  may be called  only by the
Chairman of the Board, if any, the Chief Executive Officer,  the President or by
a majority of the Board of Directors.

      OH+R. OH+R's By-laws provide that special meetings of the stockholders may
be called by the Board of Directors, the Chairman of the Board, if any, the Vice
Chairman, if any, the President,  and Vice President, any member of the Board of
Directors who is a representative of a holder of OH+R's Preferred Stock, any two
members of the Board of Directors, or the holders of at least 10% of the capital
stock of OH+R then issued and outstanding and entitled to vote at such meetings.

Liability of Directors

      The DGCL permits a corporation  to include a provision in its  certificate
of incorporation eliminating or limiting the personal liability of a director to
the corporation or its stockholders

                                     124

<PAGE>



for monetary  damages for breach of the director's  fiduciary  duty,  subject to
certain  limitations.  Each of Telor's Certificate of Incorporation and the OH+R
Certificate includes such a provision, as set forth below, to the maximum effect
permitted by law.

      Telor. Telor's Certificate of Incorporation  provides that a director will
not be personally  liable to Telor or its  stockholders for monetary damages for
breach of fiduciary duty as a director,  except for liability (i) for any breach
of the director's duty of loyalty to Telor or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL,  which concerns  unlawful
payments  of  dividends,   stock  purchases  or  redemptions  or  (iv)  for  any
transaction from which the director derived an improper personal benefit. If the
DGCL is amended to authorize  corporate  action further  eliminating or limiting
the personal  liability of  directors,  then the  liability of each  director of
Telor shall be  eliminated  or limited to the fullest  extent  permitted  by the
DGCL, as so amended.

      OH+R. OH+R's Certificate provides that no director shall be liable to OH+R
or its stockholders for monetary damages for breach of the director's  fiduciary
duty as a director,  except for liability  (i) for any breach of the  director's
duty of loyalty to OH+R or its  stockholders,  (ii) for acts or omissions not in
good faith or which involve  intentional  misconduct  or a knowing  violation of
law, (iii) under Section 174 of the DGCL or (iv) for any transaction  from which
the director  derived an improper  personal  benefit.  If the DGCL is amended to
authorize  corporate  action  further  eliminating  or limiting the liability of
directors,  then the liability of each director of OH+R shall  automatically  be
eliminated  or  limited  to the  fullest  extent  permitted  by the DGCL,  as so
amended.  Any repeal or  modification  of this  provision of OH+R's  Certificate
shall  not  adversely  affect  any right or  protection  of a  director  of OH+R
existing pursuant to this provision at the time of such repeal or modification.

Indemnification of Directors and Officers

      The DGCL permits a corporation to indemnify officers, employees and agents
for actions taken in good faith and in a manner they  reasonably  believed to be
in, or not opposed to, the best interests of the  corporation,  and with respect
to any  criminal  action,  which they had no  reasonable  cause to  believe  was
unlawful.  The DGCL provides that a corporation may advance  expenses of defense
(upon  receipt  of  a  written  undertaking  to  reimburse  the  corporation  if
indemnification  is not appropriate)  and must reimburse a successful  defendant
for expenses,  including attorneys' fees, actually and reasonably incurred,  and
permits a  corporation  to purchase and  maintain  liability  insurance  for its
directors and officers.  The DGCL provides that  indemnification may not be made
for any claim, issue or matter as to which a person has been adjudged by a court
of competent  jurisdiction,  after  exhaustion of all appeals  therefrom,  to be
liable to the corporation, unless and only to the extent a court determines that
the person is entitled to indemnity for such expenses as the court deems proper.

      Telor's  Certificate of  Incorporation  and the Telor By-laws provide that
each  person  who is  involved  in any  actual  or  threatened  action,  suit or
proceeding, whether civil, criminal,  administrative or investigative, by reason
of the fact that he or she is or was a director, officer,

                                     125

<PAGE>



employee  or agent of Telor,  or is or was  serving at the request of Telor as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture,  trust or other enterprise,  including service with respect to an
employee benefit plan, will be indemnified by Telor to the full extent permitted
by the DGCL, as the same exists or may hereafter be amended (but, in the case of
any such  amendment,  only to the extent that such  amendment  permits  Telor to
provide  broader  indemnification  rights than said law permitted  prior to such
amendment)  or by other  applicable  laws then in effect.  The OH+R By-laws also
provide for  indemnification  to the full extent  permitted  by the DGCL for any
person by reason of the fact  that such  person is or was a  director,  officer,
employee,  fiduciary  or agent of OH+R,  or is or was  serving at the request of
OH+R as a director,  officer, trustee,  fiduciary,  employee or agent of another
corporation, partnership, joint venture, trust or other enterprise.

      Insofar as  indemnification  for liabilities  arising under the Securities
Act may be  permitted  to  directors,  officers  or  persons  controlling  Telor
pursuant  to the  foregoing  provisions,  Telor  has been  informed  that in the
opinion of the SEC such indemnification is against public policy as expressed in
the Securities Act and is therefore unenforceable.

                     PROPOSALS FOR TELOR'S SPECIAL MEETING

Proposal 1:  Adoption of the Merger Agreement and the Merger

      The following  proposal is being submitted to the  stockholders  for their
consideration at the Special Meeting.  For a description of the Merger, see "THE
MERGER AND RELATED TRANSACTIONS."

      Under the Merger Agreement, OH+R will be merged with and into Telor, Telor
will be the  Surviving  Corporation  of the Merger and the name of the Surviving
Corporation will be Occupational  Health +  Rehabilitation  Inc. The business of
the Surviving  Corporation will be the business of OH+R as conducted immediately
prior to the Merger.

      Under the terms of the Merger  Agreement,  at the time of the Merger  each
share  of OH+R  Common  Stock  will be  converted  into  the  right  to  receive
approximately 0.1413123 of a share of Telor Stock, (subject to adjustment of the
Share  Conversion  Fraction  at the  Effective  Time),  and  each  share of OH+R
Preferred  Stock and certain  other equity  securities of OH+R will be converted
into the right to  receive  Telor  Stock  based on the  number of shares of OH+R
Common  Stock  into which such  share of OH+R  Preferred  Stock or other  equity
security  is then  convertible  multiplied  by the  Share  Conversion  Fraction.
Options to purchase  OH+R  Common  Stock  granted to  employees,  directors  and
consultants  of OH+R and warrants to purchase OH+R Common Stock  outstanding  at
the time of the Merger shall entitle the holder upon exercise in accordance with
the terms thereof to acquire Telor Stock pursuant to the provisions of the plan,
if any, or agreements pursuant to which they were issued.

      The affirmative vote of holders of a majority of the outstanding shares of
Telor Stock  entitled to vote at the Special  Meeting is required to approve the
Merger Agreement and the Merger.

THE BOARD OF  DIRECTORS  OF TELOR  RECOMMENDS  APPROVAL  OF THE  ADOPTION OF THE
MERGER  AGREEMENT  AND THE MERGER,  AND PROXIES  SOLICITED  BY THE BOARD WILL BE
VOTED IN FAVOR OF THE MERGER  AGREEMENT  AND  MERGER  UNLESS A  STOCKHOLDER  HAS
INDICATED OTHERWISE ON THE PROXY.

Proposal 2:  1993 Plan Amendment

      The  following  proposal  describes an amendment to the 1993 Plan which is
being  submitted  to the  stockholders  for their  consideration  at the Special
Meeting.  For a description  of the 1993 Plan as currently in effect and options
granted  under it in 1995,  see  "INFORMATION  ABOUT  TELOR - Stock Plans - 1993
Plan" above and "- Option Grants" above, respectively. For a description of OH+R
Employee Stock Options which will be converted into options under the 1993 Plan,
see "THE MERGER AND RELATED  TRANSACTIONS  - Conversion of Equity  Securities of
OH+R Pursuant to the Merger  Conversion of OH+R Employee  Stock Options and OH+R
Warrants" and "INFORMATION ABOUT OH+R - Security Ownership of Certain Beneficial
Owners  and  Management  of  OH+R."  As of  April  15,  1996,  based  on a Share
Conversion Fraction of 0.1413123 (which

                                     127

<PAGE>



may be adjusted at the  Effective  Time),  OH+R  Employee  Stock  Options  would
convert into options for 119,403  shares of Telor Stock.  The federal income tax
consequences of the issuance and exercise of options granted under the 1993 Plan
to the option recipient and to Telor are described in "INFORMATION ABOUT TELOR -
Federal Income Tax Considerations with respect to Stock Options" above.

      Under  the  terms  of the  1993  Plan,  the  plan  may be  amended  by the
Compensation  Committee of the Board of Directors or the stockholders,  provided
that any amendment  approved by the  Compensation  Committee which is of a scope
that requires  stockholder  approval in order to ensure favorable federal income
tax treatment for any incentive stock options or requires  stockholder  approval
in order to ensure the  compliance  of the 1993 Plan with Rule  16b-3  under the
Exchange Act is subject to obtaining such stockholder approval.

      A total of 140,000  shares of Telor  Stock are  currently  authorized  for
issuance  under the 1993 Plan as  currently in effect.  On March 18,  1996,  the
Compensation  Committee  voted to adopt  and  approve,  subject  to  stockholder
approval,  an  amendment  to the 1993 Plan to increase by 105,000  shares,  from
140,000 to 245,000,  the  aggregate  number of shares of Telor Stock as to which
stock  options  may be granted  under the 1993  Plan.  This  amendment  is being
submitted  for  stockholder   approval  at  the  meeting  to  ensure   continued
qualification of the plan under Rule 16b-3 under the Exchange Act.

      The increase in the number of shares  reserved for issuance under the 1993
Plan is required as a condition to the consummation of the Merger.  In addition,
the  Board  believes  that the  increase  is  advisable  to give  the  Surviving
Corporation the flexibility  needed to attract,  retain and motivate  employees,
directors and  consultants.  All  employees,  directors and  consultants  of the
Surviving  Corporation  (currently  approximately  10 people and estimated to be
approximately  120  people  if the  Merger  with  OH+R is  consummated)  will be
eligible  to  participate  in the  1993  Plan.  Adoption  of  Proposal  2 is not
conditioned  upon  adoption of Proposal 1, the  approval of the  adoption of the
Merger Agreement and the Merger. However,  approval of the amendment to the 1993
Plan is a condition to consummation of the Merger.

      No  determination  has been made as to the recipients of options under the
1993 Plan as a result of the  increase  in the number of shares  authorized  for
issuance  thereunder.  However, the 1993 Plan does provide for certain automatic
grants as described in "INFORMATION ABOUT TELOR - Stock Plans - 1993 Plan."

      The  affirmative  vote of holders of a majority  of the shares  present or
represented  and entitled to vote at the Special  Meeting is required to approve
the increase in the  aggregate  number of shares of Telor Stock  authorized  for
issuance under the 1993 Plan.

THE BOARD OF DIRECTORS  RECOMMENDS  APPROVAL OF THE ADOPTION OF THE AMENDMENT TO
THE 1993 PLAN TO  INCREASE  BY  105,000  SHARES THE  AGGREGATE  NUMBER OF SHARES
AUTHORIZED FOR ISSUANCE UNDER THE 1993 PLAN, AND PROXIES  SOLICITED BY THE BOARD
WILL BE VOTED IN FAVOR OF SUCH  AMENDMENT  UNLESS A  STOCKHOLDER  HAS  INDICATED
OTHERWISE ON THE PROXY.


                                     128

Proposal 3:  Amendment to Telor's Certificate of Incorporation

      The following  proposal  describes an amendment to Telor's  Certificate of
Incorporation   which  is  being  submitted  to  the   stockholders   for  their
consideration at the Special Meeting.

      Under the  Certificate  of  Incorporation,  Telor is  authorized  to issue
30,000,000 shares,  consisting of 25,000,000 shares of Telor Stock and 5,000,000
shares of preferred stock.

      Telor no longer  requires  such a large  number of  authorized  shares and
believes that  10,000,000  shares of Telor Stock will be a sufficient  number of
shares whether or not the Merger is consummated. Moreover, the amount of Telor's
franchise tax obligation to the State of Delaware will be reduced  substantially
by decreasing the number of shares of stock that Telor is authorized to issue.

      The Board of Directors  has  approved  the  proposed  amendment to Telor's
Certificate  of  Incorporation,  and the Board believes that the amendment is in
the best interest of Telor and advisable. There are no other proposed changes to
Telor's Certificate of Incorporation.

      The proposed amendment provides that Article Fourth of Telor's Certificate
of  Incorporation  be amended (i) by deleting  "Thirty Million  (30,000,000)" in
sentence 1 of paragraph A and replacing it with "Fifteen Million  (15,000,000)";
and (ii) by deleting  "25,000,000" in sentence 1 of paragraph A and replacing it
with "10,000,000".

      The affirmative vote of holders of 70% of the outstanding  shares of Telor
Stock  entitled  to vote at the  Special  Meeting is  required  to  approve  the
amendment to Telor's Certificate of Incorporation.

THE BOARD OF  DIRECTORS  OF TELOR  RECOMMENDS  APPROVAL  OF THE  ADOPTION OF THE
CERTIFICATE OF INCORPORATION AMENDMENT TO DECREASE THE NUMBER OF SHARES OF TELOR
STOCK AUTHORIZED TO BE ISSUED,  AND PROXIES SOLICITED BY THE BOARD WILL BE VOTED
IN FAVOR SUCH  AMENDMENT  UNLESS A STOCKHOLDER  HAS  INDICATED  OTHERWISE ON THE
PROXY.

                                 OTHER MATTERS

      The Board of Directors  knows of no other business which will be presented
to the Special  Meeting.  If any other  business is properly  brought before the
meeting,  it is  intended  that  proxies in the  enclosed  form will be voted in
respect  thereof in  accordance  with the  judgment  of the  persons  voting the
proxies.


                             STOCKHOLDER PROPOSALS

      To be considered for presentation at the Annual Meeting of Stockholders to
be  held  in  1996,  stockholder  proposals  must be  received,  marked  for the
attention of the Secretary of the Corporation, Telor Ophthalmic Pharmaceuticals,
Inc., 790 Turnpike Street, Suite 202, North
Andover, Massachusetts 01845 not later than December 15, 1995.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To Telor Ophthalmic Pharmaceuticals, Inc.:

We  have  audited  the   accompanying   balance   sheets  of  Telor   Ophthalmic
Pharmaceuticals,  Inc. (a Delaware  corporation in the development  stage) as of
December  31,  1994  and  1995,  and  the  related   statements  of  operations,
stockholders'  equity  (deficit) and cash flows for the years ended December 31,
1993, 1994 and 1995 and for the period from April 19, 1988  (inception)  through
December 31, 1995.  These  financial  statements are the  responsibility  of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all   material   respects,   the   financial   position   of  Telor   Ophthalmic
Pharmaceuticals,  Inc. as of December 31, 1994 and 1995,  and the results of its
operations and its cash flows for the years ended  December 31, 1993,  1994, and
1995 and for the period from April 19, 1988  (inception)  through  December  31,
1995, in conformity with generally accepted accounting principles.

      TELOR OPHTHALMIC PHARMACEUTICALS, INC. (A Development Stage Company)

                          NOTES TO FINANCIAL STATEMENTS
(1)  Operations

     Telor  Ophthalmic  Pharmaceuticals,  Inc.  ("Telor" or the  "Company")  was
     incorporated on April 19, 1988. The Company obtained its initial  financing
     and commenced operations on November 17, 1988. Since inception, the Company
     has devoted substantially all of its efforts in research and development of
     products for use in ophthalmic surgery and age-related diseases of the eye,
     and towards raising capital.

     On August 9, 1995,  Telor announced that its preliminary  analysis of Phase
     III clinical trials of its lead product  candidate,  XARANO(TM),  indicated
     that the  trials did not  support  continuation  of the XARANO  development
     program.  Separately,  the Company also announced  positive  results of its
     Phase  I/II  trial of a  compound  to  reduce  surgical  miosis,  a problem
     associated with cataract surgery. On August 30, 1995, the Company announced
     a restructuring with a workforce reduction designed to substantially reduce
     Telor's rate of cash use for  operations.  The Company also  announced  its
     intention  to  find  and  evaluate  business   opportunities,   potentially
     including  identifying a merger candidate,  seeking  corporate  partners to
     support  the  clinical  program for  surgical  miosis,  or  exploring a new
     business  direction.  During  the  fourth  quarter  of  1995,  the  Company
     substantially curtailed its research and development activities.

     On December 7, 1995, the Company  announced it had entered into a letter of
     intent to merge with Occupational Health + Rehabilitation Inc. Occupational
     Health +  Rehabilitation  Inc, an early stage company,  develops,  owns and
     operates   multi-disciplinary   outpatient  health  care  centers  for  the
     prevention,   treatment  and  management  of   work-related   injuries  and
     illnesses.  On February 23, 1996, the Company announced it had entered into
     an Agreement and Plan of Merger to merge the two companies.

     Effective  November 30, 1995, the Company  retained one employee,  and both
     the Acting Chief Executive Officer and certain former employees continue to
     serve the Company on a consulting basis. Ongoing expenses consist mainly of
     those  associated with the prospective  merger,  with the Company's  leased
     facility in  Wilmington,  MA, for which the Company is actively  seeking to
     obtain  a  sublessee  or  replacement  lessee,  and with  certain  expenses
     associated with being a public company.

(2)  Summary of Significant Accounting Policies

     The accompanying  financial  statements  reflect the application of certain
     significant  accounting  policies,  as discussed below and elsewhere in the
     notes  to  financial  statements.   The  preparation  of  the  accompanying
     financial statements required the use of certain estimates by management in
     determining the Company's assets,  liabilities,  revenues and expenses. The
     estimated fair value of the Company's financial instruments,  which include
     cash  equivalents,  accounts  receivable and long-term  debt,  approximates
     their carrying value.

     (a) Depreciation and Amortization

         The  Company  provides  for  depreciation  and  amortization  using the
         straight-line  method by charges to operations in amounts  estimated to
         allocate  the cost of the assets over their  estimated  useful lives as
         follows:

(2)  Summary of Significant Accounting Policies (Continued)

     (a)  Depreciation and Amortization (Continued)

                                                                Estimated
                            Asset Classification                Useful Life
                            --------------------                -----------
                      Laboratory equipment                        7 years
                      Computer equipment                          3 years
                      Furniture and fixtures                      5 years
                      Leasehold improvements                      Life of lease

          As part of the  restructuring  announced  August 30, 1995, the Company
          wrote  down  its  fixed  assets  to net  realizable  value.  Leasehold
          improvements  have  been  written  down to  zero,  as the  Company  is
          currently  seeking to  sublease  its  facility  and does not expect to
          recover  any  portion  of  the  cost  of its  leasehold  improvements.
          Substantially   all  of  the  fixed  assets,   other  than   leasehold
          improvements, have been sold.

     (b)  Research and Development Expenses

          The Company  historically charged research and development expenses to
          operations  as incurred.  The Company has  curtailed  its research and
          development activities.

     (c)  Income Taxes

          During 1993, the Company  adopted the accounting and disclosure  rules
          of  Statement  of  Financial   Accounting   Standards  (SFAS)  No.109,
          Accounting  for Income Taxes.  The adoption of this  Statement did not
          have a material effect on the Company's  financial position or results
          of operations.

          At December 31, 1995, the Company had net operating loss carryforwards
          for financial reporting and tax purposes of approximately  $31,067,000
          and $30,344,000 respectively,  and research and development tax credit
          carryforwards  of  approximately  $735,000.  These  carryforwards  are
          available  for the  reduction  of future  federal  taxable  income and
          income taxes, if any, through 2010. The principal  differences between
          financial  reporting  and income tax  carryforwards  are the result of
          capitalizing  research and development expenses for tax purposes.  The
          carryforwards  are subject to review and  possible  adjustment  by the
          Internal  Revenue  Service.  In addition,  the  Internal  Revenue Code
          contains  provisions  that may  limit the net  operating  loss and tax
          credit  carryforwards  available to be used in any given year upon the
          occurrence  of  certain  events,  including  a  significant  change in
          ownership of the Company.

          The merger  discussed in Note 9 is considered a significant  change in
          ownership,  and as a result,  substantially  all of the  Company's net
          operation  loss  carryforwards  will not be  available  to offset  any
          future income.

                                                                ============

          A valuation  allowance  has been  provided as it is probable  that the
          Company will not realize the deferred tax asset.

     (d)  Net Loss per Common Share

          In connection  with the Company's  May 1993 initial  public  offering,
          1,926,956 shares of preferred stock were converted into 385,391 shares
          of common stock (as adjusted for the November  1995  1-for-10  reverse
          stock  split;  see note 5a). Net loss per common share is based on the
          weighted average number of common shares outstanding, giving effect to
          the conversion of preferred stock as of the issuance date. Pursuant to
          the requirements of the Securities and Exchange Commission, common and
          preferred stock issued by the Company during the 12 months immediately
          preceding  the initial  public  offering,  plus shares of common stock
          which became  issuable during the same period pursuant to the grant of
          common  stock  options,  have  been  included  in the  calculation  of
          weighted  average  number of common  shares  outstanding  for the year
          ended December 31, 1993 computed in accordance with the treasury stock
          method.

     (e)  Postretirement Benefits

          The Company has no obligations for postretirement  benefits under SFAS
          No. 106, Employers' Accounting for Postretirement  Benefits Other Than
          Pensions, since it does not currently offer such benefits.

(3)  Cash, Cash Equivalents, Short-Term Investments and Restricted Cash

     (a)  Cash and Cash Equivalents

          The Company  considers  all highly  liquid  investments  with original
          maturities  of  three  months  or less to be cash  equivalents.  As of
          December 31, 1994 and 1995, cash and cash equivalents consist of money
          market accounts and bank certificates of deposit.

     (Continued)

     (b)  Short term Investments

          Short term investments are securities with original maturities greater
          than three  months but less than one year.  During  1994,  the Company
          adopted SFAS No. 115,  Accounting for Certain  Investments in Debt and
          Equity  Securities.   Accordingly,   the  Company's   investments  are
          classified  as held to  maturity  (recorded  at  amortized  cost)  and
          available for sale (recorded at fair market value) as follows:

          The adoption of this  statement did not have a material  effect on the
          Company's  financial  position or results of  operations  for the year
          ended December 31, 1994.

     (c)  Restricted Cash

          The  Company  issued  two  $200,000  letters  of  credit in 1994 for a
          one-year  term to the  lessor of its  facility  in  Wilmington,  MA in
          connection  with its lease of said  facility (see note 7), and renewed
          those letters of credit for a one-year term in June,  1995.  Under the
          terms of the lease,  the Company is  committed to maintain the letters
          of credit,  but may  reduce  the  amount of each by $20,000  annually,
          beginning on October 14, 1995.  At December 31, 1995,  the Company was
          required to  maintain  these  letters of credit in an amount  totaling
          $360,000.

          The Company has two  $200,000  certificates  of deposit  with the bank
          that issued said  letters of credit in security  thereof.  At December
          31,  1994,  the Company  reported  the two  $200,000  certificates  of
          deposit,  a total of $400,000,  as  restricted  cash.  At December 31,
          1995, the Company  reported  $360,000 of this, the amount securing the
          required amount of the letters of credit, as restricted cash.

     (5)  Stockholders' Equity

     (a)  Reverse Stock Splits

          During March and April 1993,  the  Company's  Board of  Directors  and
          Stockholders,  respectively, approved a 1-for-5 reverse stock split of
          the common stock.  During  September and November  1995, the Company's
          Board of Directors and Stockholders, respectively, approved a 1-for-10
          reverse  stock split of the common stock.  Accordingly,  all share and
          per share amounts of common stock for all periods  presented have been
          retroactively adjusted to reflect these reverse stock splits.

     (b)  Initial Public Offering

          The Company completed its initial public offering through the sale, on
          May 18, 1993 and June 10, 1993, of a total of 287,500 shares of common
          stock at a per share  price of $80.00 (as  adjusted  for the  November
          1995 1-for-10  reverse stock split;  see note 5a). Net proceeds of the
          offering  were  $20,620,000   after  selling   commissions  and  other
          expenses.  In connection with the initial public offering,  all series
          of preferred stock were automatically converted into 385,391 shares of
          common stock.

     (c)  Employee Stock Purchase Plan

          During  1993,  the  Company's  Board  of  Directors  and  Stockholders
          approved  the  Employee  Stock  Purchase  Plan,  pursuant to which the
          Company may issue up to 10,000 shares of common stock to participating
          employees, as defined. Under this plan, shares of the Company's common
          stock may be purchased at the end of a six-month  period at the lesser
          of 85% of the  fair  market  value  on the  date of  grant  or date of
          exercise.  As of December 31, 1995, 2,865 shares had been issued under
          this plan, and no employees were participating in the plan.

     (d)  1988 Stock Plan and 1993 Stock Plan

          Pursuant to the 1988 Stock Plan, the Company may grant incentive stock
          options, non-qualified stock options and common stock purchase rights.
          The Company has  reserved  48,453  shares of common stock for issuance
          under this plan (as adjusted for the November,  1995 1-for-10  reverse
          stock split; see note 5a).

          During  1993,  the  Company's  Board  of  Directors  and  Stockholders
          approved  the 1993 Stock Plan  pursuant to which the Company may grant
          incentive and  non-qualified  options to purchase up to 140,000 shares
          of the  Company's  common stock (as adjusted  for the  November,  1995

</TABLE>

          During 1992, the Company recorded  deferred  compensation of $512,000,
          which represented the excess of the fair market value per share on the
          option grant date as estimated for financial reporting purposes,  over
          the exercise  price of certain  options  granted  under the 1988 Stock
          Plan. The Company's  Board of Directors  granted such stock options at
          per share exercise prices which it believed to be at or above the fair
          market value of the underlying  common stock at the time of grant.  In
          light of the initial  public  offering of the Company's  common stock,
          the Company utilized per share market

          prices  in  excess  of such  exercise  prices  in  computing  deferred
          compensation for financial reporting  purposes.  During 1993, 1994 and
          1995,   the  Company   reversed   $34,749,   $48,080   and   $138,159,
          respectively,   of  the  deferred  compensation  relating  to  options
          forfeited by terminated  employees,  and included compensation expense
          in  the  results  of   operations   $78,123,   $86,243  and   $71,646,
          respectively, related to the amortization of deferred compensation. At
          December 31, 1995,  all of the deferred  compensation  had been either
          amortized or reversed.

          On January 31, 1995,  the Company  offered all then current  employees
          the opportunity to forfeit certain outstanding options in exchange for
          new grants of options,  exercisable for an equal number of shares,  at
          an exercise price per share of $8.75, equal to the closing stock price
          on January 31,  1995 (as  adjusted  for the  November,  1995  1-for-10
          reverse  stock  split;  see note 5a).  Options for 18,926  shares were
          exchanged.  As of January  17,  1996,  none of these  options had been
          exercised,  and options for 2,609  shares were  outstanding,  with the
          balance forfeited by terminated  employees.  These outstanding options
          expire on or before November 29, 1996.

(6)  Commitments and Contingencies

     (a)  Capital and Operating Leases

          In  July,  1994,  the  Company  entered  into a lease  agreement  that
          terminates   October   31,   2004  for  a  facility   in   Wilmington,
          Massachusetts.  The Company has the right to terminate the lease after
          five years and payment of a fee of approximately  $60,000. The Company
          also has the right to extend the lease for an  additional  five years,
          subject to certain conditions.

          In  connection  with the  facility  lease,  the  Landlord has financed
          $600,000 of leasehold  improvements at 9% per annum, which the Company
          has accounted for as a capital lease.  The capital lease is payable in
          monthly  payments of principal and interest of $7,601 through  October
          31,  2004.  If the  Company  terminates  the  lease at the end of five
          years,  the unpaid balance is due on the lease  termination  date. The
          Company was required to have a total of $400,000 in secured letters of
          credit at the  initiation of the lease and must maintain these letters
          of  credit  for the  term of the  lease,  subject  to a 10%  reduction
          annually at the Company's  option.  The cash that secures the required
          amount of the letters of credit has been classified as restricted cash
          in the accompanying balance sheet.

          The Company is actively  seeking to obtain one or more  sublessees for
          its facility in Wilmington,  MA, or to terminate the lease by securing
          one or more replacement  lessees.  The Company  currently  anticipates
          that a lease  with one  sublessee  will be  signed on or about May 15,
          1996,  subject to obtaining  written  consent to the sublease from the
          landlord.  The Company is currently  conducting  no  operations at the
          Wilmington  facility,  but is  responsible  for its share of operating
          costs of the facility,  including taxes,  insurance,  maintenance and,
          subject to certain limitations, repairs.

          The Company also leases  certain office  equipment  under an operating
          lease.

          Rent expense totaled approximately $143,000, $193,000 and $286,000 for
          the years ended December 31, 1993, 1994 and 1995, respectively.

     (b)  Commitments

          In March 1996, the Company's employee received a payment equivalent to
          six  months'  salary  at his then  current  salary  rate,  notice  pay
          equivalent to two week salary, and accrued vacation. In addition,  the
          Company will  maintain the  employee's  medical,  life and  disability
          insurance coverage for six months, subject to certain conditions.

(7)  401(k) Plan

     During 1992,  the Company  adopted an employee  benefit plan under  Section
     401(k) of the  Internal  Revenue  Code.  The plan allows  employees to make
     contributions up to a specified percentage of their compensation. Under the
     plan,  the  Company  may  elect  to  match  a  portion  of  the  employees'
     contribution  up to a defined  maximum.  To date,  the  Company has made no
     contributions  to the plan.  The Company has committed to continue the plan
     until the  earlier  of  September  30,  1996 or when all  former  employees
     voluntarily transfer or withdraw their funds from the plan.

                   NOTES TO FINANCIAL STATEMENTS - (Continued)

     The Company's statement of operations for the year ended December 31, 1994,
     includes  a  $609,000  or $.80 per  share,  charge  to  provide  for  costs
     associated  with the  termination in November 1994, of the Tekron  program.
     The  restructuring  charge  included  approximately  $359,000 of  severance
     payments for the reduction of the workforce in November  1994, and $250,000
     of other reserves, chiefly related to the Company's corporate headquarters.
     The  Company's  financial  statements  included  reserves  related  to this
     restructuring  of $466,000  and zero for the years ended  December 31, 1994
     and December 31, 1995, respectively.

     The Company's statement of operations for the year ended December 31, 1995,

     restructuring charge included  approximately $640,000 of severance payments
     for the reduction of the workforce from August  through  November 1995, and
     $1,360,000  related to the writedown of fixed assets,  including  leasehold
     improvements,  to net realizable value and to anticipated  costs associated
     with obtaining a sublessee or replacement  lessee for the Company's  leased
     facility in Wilmington, MA. The Company's financial statements for the year
     ended December 31, 1995 included reserves related to this  restructuring of
     $356,000.


(9)  Subsequent Event - Merger

     On February 23, 1996, Telor announced that it had entered into an Agreement
     and Plan of Merger to merge with Occupational  Health + Rehabilitation  Inc
     ("OH+R").  OH+R,  an early  stage  company,  develops,  owns  and  operates
     multi-disciplinary,  outpatient  health care  centers  for the  prevention,
     treatment  and  management  of  work-related  injuries and  illnesses.  The
     companies  had  announced  in  December,  1995 that they had entered into a
     letter of intent to merge.

     The  transaction  is  structured  as a merger of OH+R into Telor.  Upon the
     merger,  the  stockholders  of OH+R will receive  shares of Telor's  common
     stock and holders of options or warrants for shares of OH+R  capital  stock
     will  hold  options  and  warrants  exercisable  for  Telor  common  stock.
     Immediately following the merger, the OH+R stockholders,  together with its
     option and  warrant  holders,  will hold or have the right to  purchase  an
     aggregate  of 50% of the  shares  of  common  stock of Telor  and the Telor
     stockholders, together with its option holders, will hold or have the right
     to purchase an aggregate of 50% of the shares of common stock of Telor.

     The  transaction  is  expected  to be  consummated  in April of 1996.  Upon
     closing of the merger,  the company's primary business will be the business
     of  OH+R  and  Telor  will  change  its  name  to  Occupational   Health  +
     Rehabilitation Inc.


<PAGE>


     The  merger is  considered  a  significant  change in  ownership,  and as a
     result,  substantially  all of the net operating loss  carryforwards of the
     Company will not be available to offset any future income. See Note 2(c).

     The following table presents selected financial  information  assuming that
     the Company and OH+R had combined at the beginning of 1995.

                                                             Amount in thousands
                                                             -------------------
     Pro forma net revenues .................................      $  6,024
     Pro forma net loss .....................................      $ (9,311)
     Pro forma net loss per share ...........................      $  (6.48)
     Pro forma weighted average common
     and common equivalent shares ...........................         1,440
     Pro forma total assets .................................      $ 10,136

     The pro forma  results  are not  necessarily  indicative  of either  actual
     results of  operations  that would have occurred had the  acquisition  been
     made at the beginning of 1995 or future results.

                         Report of Independent Auditors


Board of Directors
Occupational Health + Rehabilitation Inc

We have audited the  accompanying  consolidated  balance sheets of  Occupational
Health +  Rehabilitation  Inc and subsidiaries as of December 31, 1995 and 1994,
and the related  consolidated  statements of  operations,  stockholders'  equity
(deficit),  and cash  flows  for each of the  three  years in the  period  ended
December 31, 1995.  These  financial  statements are the  responsibility  of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly,  in all  material  respects,  the  consolidated  financial  position  of
Occupational  Health + Rehabilitation  Inc and subsidiaries at December 31, 1995
and 1994, and the consolidated  results of its operations and its cash flows for
each of the three years in the period ended  December 31,  1995,  in  conformity
with generally accepted accounting principles.

                                December 31, 1995


1.  Summary of Significant Accounting Policies

Business

Occupational  Health + Rehabilitation  Inc, formerly  Occupational  Health, Inc.
(the Company),  a Delaware  corporation,  was  incorporated  on May 15, 1992 for
purposes of acquiring  Occupational  Orthopedic  Center,  Inc.  (OOC) on July 1,
1992. The Company had no significant operations prior to that date.

The Company develops and operates outpatient medical centers specializing in the
prevention, treatment and management of work-related injuries and illnesses. The
Company operates the centers under long-term  service  agreements with physician
and physical therapy groups that practice exclusively through such centers.

Effective April 1, 1995, the Company  entered into a partnership  agreement with
NEB  Enterprises,  Inc.,  forming NEB  Occupational  Health (NEBOH),  to provide
management and related  services to the centers  established by the partnership.
(see Note 2).

Basis of Presentation

The Company's  consolidated  financial statements have been presented on a going
concern basis which  contemplates the realization of assets and the satisfaction
of liabilities in the normal course of business. The Company generated losses of
$1,776,411  during the year ended December 31, 1995 and cumulative net losses of
$4,691,899  during the three year period then ended.  As an early stage company,
the Company has predictably  generated losses as it has developed its network of
rehabilitation  centers. The Company's cash flow needs have been met through the
infusion of capital from venture capital investors through the sale of preferred
stock. At December 31, 1995,  management's plan for the 1996 year indicates that
another of infusion of capital will be necessary to meet both operational  needs
and requirements for potential acquisitions. As more fully described in Note 14,
the  Company  has  signed a letter  of  intent to merge  into  Telor  Ophthalmic
Pharmaceuticals,  Inc. (Telor). Telor has adequate cash resources to ensure that
the Company can continue as a going concern  through  December 31, 1996.  Should
the merger with Telor not be  consummated,  management will seek funding through
the Company's venture capital investors or other financing sources.

Principles of Consolidation

The  consolidated  financial  statements  include the  accounts of  Occupational
Health + Rehabilitation Inc, its wholly-owned  subsidiary and its majority-owned
partnership,  NEBOH. All significant intercompany accounts and transactions have
been eliminated.


                                                                               7

             Notes to Consolidated Financial Statements (continued)


1.  Summary of Significant Accounting Policies (continued)

Cash and Cash Equivalents

The Company  considers  all highly liquid  investments  with a maturity of three
months or less at date of purchase to be cash equivalents.

Property and Equipment

Property and equipment is stated on the basis of cost.  Depreciation of property
and  equipment  is  calculated  using the  straight-line  and  declining-balance
methods over the estimated  useful lives of the assets.  Leasehold  improvements
are amortized on a straight-line basis over the shorter of the lease term or the
estimated  useful life of the asset.  Amortization of assets under capital lease
is included with depreciation.

Intangible Assets

Excess Cost of Net Assets Acquired

The excess of cost over the fair value of the net assets of businesses  acquired
(goodwill) is amortized using the straight-line  method over periods of 20 to 40
years.

Noncompetition Agreements

Covenants  not-to-compete  are  amortized  over the  term of the  noncompetition
agreement, which is currently five years.

Organization Costs

Costs of organizing the Company are being amortized over a period of five years.

The  carrying  value of  intangible  assets  will be  reviewed  if the facts and
circumstances  suggest that it may be impaired. If this review indicates that an
intangible  asset will not be  recoverable,  an impairment loss is recognized to
the extent the sum of the  undiscounted  expected future cash flows is less than
the carrying amount of the asset.  Measurement of impairment  should be based on
the fair value of the asset. No such impairment exists at December 31, 1995.


                                                                               8

             Notes to Consolidated Financial Statements (continued)


1.  Summary of Significant Accounting Policies (continued)

In March 1995,  the Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards  No. 121,  "Accounting  for the  Impairment  of
Long-Lived   Assets  and  for  Long-Lived  Assets  to  be  Disposed  Of,"  which
establishes  criteria for the  recognition  and  measurement of impairment  loss
associated  with long-lived  assets.  The Company will be required to adopt this
Standard  in  the  first  quarter  of  1996.  Based  on  the  Company's  initial
evaluation,  adoption is not expected to have a material impact on the Company's
financial position or results of operations.

Net Patient Service Revenue

Net patient  service  revenue for all centers is recorded at  established  rates
reduced by allowances for doubtful accounts and contractual  adjustments,  which
amounted to $801,076,  $321,168  and  $321,896 for the years ended  December 31,
1995, 1994 and 1993, respectively.

Professional Liability Coverage

The Company maintains professional liability insurance coverage on a claims-made
basis in Maine and Rhode Island, and on an occurrence basis in Massachusetts and
Vermont. Management is unaware of any claims that may result in a loss in excess
of amounts covered by its existing insurance.

Stock Option Accounting

The  Company  accounts  for  its  stock  compensation   arrangements  under  the
provisions of APB 25, "Accounting for Stock Issued to Employees," and intends to
continue to do so.

Estimates and Assumptions

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets  and  liabilities,  if  any,  at the  date  of the  financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

1.  Summary of Significant Accounting Policies (continued)

Fair Value of Financial Instruments

The  Company's  financial  instruments  consist  of cash and  cash  equivalents,
accounts receivable,  accounts payable and accrued expenses,  long-term debt and
obligations  under  noncompetition  agreements.  The Company  believes  that the
carrying value of its financial instruments approximates fair value. The Company
has made  this  determination  for its  fixed-rate  long-term  debt  based  upon
interest rates currently available to it to refinance such debt.

Net Loss Per Common Share

Net loss per share of common  stock is computed by dividing  net loss,  adjusted
for  preferred  stock  dividends,  by the  weighted-average  number of shares of
common stock outstanding during each period presented. The effect of options and
warrants is not considered as it would be antidilutive.

Reclassifications

Certain reclassifications of 1994 amounts have been made to permit comparison.

2.  Acquisitions and Joint Ventures

During  1994,  the Company  purchased  substantially  all the net assets of Link
Performance and Recovery Systems,  Inc., an outpatient medical center located in
Maine. The purchase price was $247,938 which was paid in cash and 137,842 shares
of Series 2 preferred stock. The transaction was accounted for as a purchase.

Effective  April 1995, the Company entered into a partnership,  NEBOH,  with NEB
Enterprises,  Inc.  (NEBE),  a  wholly-owned  subsidiary of New England  Baptist
Hospital,  to provide management and related services to the centers established
by the partnership. The Company made a capital contribution to NEBOH of $204,000
in cash and has a  partnership  interest  equal to 51%.  In  addition,  OH+R has
control of the  business  and affairs of the  partnership  through its  majority
control of the Management  Committee.  The Management  Committee consists of two
persons  designated  by  NEBE  (the  minority  shareholder)  and  three  persons
designated  by  OH+R.  Therefore,  OH+R  has  majority  voting  control  of  the
partnership and consolidates the partnership in its financial statements.  Under
the terms of a related  agreement,  the Company issued a promissory note payable
to NEBE in the amount of  $536,446  and  incurred  a  short-term  obligation  of
$104,908 to NEBE for the purchase of 51% of the assets,  properties  and rights,
both tangible and  intangible,  in the Waltham center owned by NEBE and operated
by the Company.  NEBE acquired from the Company a 49% interest in certain of the
Company's


                                                                              10

Boston center assets. These exchanges of assets of the Waltham center and Boston
center were  consummated  at the fair value of the tangible and  intangible  net
assets of the centers.  Goodwill of $337,464 was recorded by OH+R in  connection
with these transactions.  Both the Company and NEBE contributed their respective
interests in the Waltham and Boston centers to the  partnership.  The promissory
note, at the option of the holder,  may be converted into shares of common stock
of the Company.  As a result of the Company's  interest to merge with Telor (see
Note 14),  the seller  has  agreed to waive the right to  convert  the note into
shares of common stock of the Company.

In May 1995, the Company  purchased  substantially  all of the assets (excluding
accounts  receivable) of Family Health Care, P.A., a physician  practice located
in Bangor,  Maine. The purchase price was $105,000,  consisting of 20,000 common
stock shares of the Company and a promissory  note. At the option of the holder,
principal  payments may be made in shares of common  stock of the Company.  As a
result of the Company's intent to merge with Telor (see Note 14), the seller has
agreed to waive the right to receive such shares under the promissory  note. The
note is secured by certain assets of the Company. This transaction was accounted
for as a purchase.

In June 1995, the Company  purchased  substantially all of the assets (excluding
accounts  receivable) of Green Mountain Sports Physical  Therapy,  an outpatient
therapy center located in Vermont.  The purchase price was $400,000,  consisting
of cash and a promissory note. At the option of the holder,  principal  payments
may be made in  shares  of  common  stock of the  Company.  As a  result  of the
Company's  intent to merge with  Telor  (see Note 14),  the seller has agreed to
waive the right to receive shares under the promissory note. The note is secured
by certain  assets of the  Company.  This  transaction  was  accounted  for as a
purchase.

Certain purchase  agreements require  additional  payments if specific financial
targets are met. In 1995, no additional payments were made.

3.  Management Agreements

New England Baptist Hospital

On April 1, 1993,  the Company  entered  into a  management  agreement  with New
England  Baptist  Hospital in Boston,  Massachusetts.  Under the agreement,  the
Company  operated an  outpatient  medical  center in Waltham,  Massachusetts  in
return for management fees. The management agreement terminated when the Company
entered into a partnership  agreement with NEBE (see Note 2). Management fees of
$21,555,  $108,580 and $88,655 were earned in 1995, 1994 and 1993, respectively,
under this agreement.


                                                                              11

3.  Management Agreements (continued)

NEB Occupational Health

Effective April 1995, NEBOH entered into a management agreement with New England
Baptist Hospital. Under the terms of the agreement, NEBOH operates an outpatient
medical  center in Waltham,  Massachusetts  in return for a fee equal to the net
revenue (as defined) of the center,  less certain primary expenses.  Fees earned
during 1995 were  $589,363,  comprised of $705,411 of net revenue,  less primary
expenses of  $116,048.  Such  revenue and  expenses  are included in net patient
service revenue, and cost of services and administrative expenses, respectively,
in the consolidated statement of operations.

Effective April 1995, the Company  entered into a  submanagement  agreement with
NEBOH. Under the terms of the agreement, the Company operates outpatient medical
centers in Waltham  and Boston,  Massachusetts  in return for  management  fees.
Management fees of $167,768 were earned in 1995 under this agreement.

4.  Sale of Accounts Receivable

In  June  1995,  the  Company  entered  into  an  agreement  with  NPF-WL,  Inc.
(Purchaser) and National Premier Financial Services,  Inc. (Servicer) of Dublin,
Ohio for the sale of receivables from certain Company  centers.  Under the terms
of  this  agreement,  certain  eligible  medical  receivables  are  sold  to the
Purchaser on a weekly  basis.  Up to  $1,200,000,  ongoing,  is available to the
Company.  Total proceeds during 1995 were $1,857,978  under this agreement.  The
Company is required to maintain  credit reserves with the Purchaser equal to 17%
of the total  outstanding  purchase and to pay interest equal to 1.17% per month
on the outstanding purchase balance. The Company paid $72,134 in interest during
1995.  At December  31,  1995,  the  outstanding  purchase  was $626,897 and was
appropriately  recorded  as a  deduction  of  accounts  receivable.  The Company
maintained  credit  reserves of $116,056 at December  31, 1995 in other  current
assets.

depreciation for tax return purposes.  The components of the Company's  deferred

At December 31,  1995,  the Company had net  operating  loss  carryforwards  for
federal income tax purposes of approximately $4,624,878 which begin to expire in
2008. For financial reporting purposes,  a valuation allowance of $1,862,901 has
been recognized to offset deferred tax assets related to this carryforward since
uncertainty exists with respect to future realization of such carryforwards.

10.  Stockholders' Equity and Redeemable Preferred Stock

In  April  1995,  the  Company  adopted  a  Certificate  of  Amendment  of their
Certificate of Incorporation  which increased the authorized number of shares of
Common  Stock of the Company from  6,000,000  to  8,000,000  shares and Series 2
Preferred  Stock from  2,500,000 to 3,000,000  shares.  The Company has reserved
5,514,575  shares of Common  Stock for  future  issuance  under the terms of the
Preferred Stock, Warrant, Stock Option and NEBE Note Agreements.

Preferred Stock

Each  share of  Series 1 and  Series 2  Preferred  Stock  (Preferred  Stock)  is
convertible  into one share of common  stock,  subject to certain  anti-dilution
requirements, and will automatically convert immediately prior to the closing of
an initial public offering at a price of at least $4.50 per share. Each share of
Preferred  Stock is entitled  to one vote.  Dividends  are  payable  when and if
declared by the Board of Directors  and accrue at an annual  cumulative  rate of
$.125  and  $.150  per share on the  Preferred  Stock,  respectively.  Dividends
accrued on the Series 1 Preferred  Stock totaled  $200,000 in each of 1995, 1994
and 1993.  Dividends  accrued on the Series 2 Preferred Stock totaled  $360,676,
$220,113 and $91,667 for 1995, 1994 and 1993, respectively.

In the event of voluntary or involuntary  liquidation,  distribution  of assets,
dissolution or winding up of the Company, and after payment in full of all debts
and other  obligations  of the Company,  the holders of the Preferred  Stock are
entitled to receive an amount equal to $1.25 and $1.50, respectively,  per share
plus all accrued but unpaid dividends, whether or not declared.

At any time after July 1998, any holder of Preferred Stock shall have the right,
at such  holder's  option,  to require  the Company to redeem all or part of the
Preferred Stock at a redemption value of $1.25 plus all unpaid dividends for the
Series 1 Preferred  Stock and $1.50 plus all unpaid  dividends  for the Series 2
Preferred Stock.

At any time after July 1999,  the Company may redeem all, but not less than all,
of the  Preferred  Stock at the same  redemption  values  noted in the  previous
paragraph.

In April 1995, the Company issued 400,000 shares of Series 2 Preferred Stock and
received proceeds of $600,000.

repurchase agreements.

Warrants

In  conjunction  with the  acquisition of OOC and the sale of Series 1 Preferred
Stock (see Note 1 and Preferred Stock section  above),  the Company issued stock
purchase  warrants.  The  warrants  provide the holders the right to purchase an
aggregate of 148,150 shares of common stock at $1.25 per share. The warrants are
exercisable in part or whole from July 1, 1997 until August 31, 1997.

Stock Plan

The  Company's  Stock Plan  provides  the  opportunity  for  employees,  related
corporations,  directors  and  consultants  to be granted  options to  purchase,
receive awards or make direct purchases of up to 870,951 shares of the Company's
common stock. Options granted under the Plan may be "incentive stock options" or
"nonqualified  options" under the applicable  provisions of the Internal Revenue
Code. The exercise price of "incentive stock options" granted under the plan may
not be less than the fair market value of the Company's common stock at the date
of grant.  "Nonqualified  options"  may not be  granted at less than 50% of fair
market value.

13.  Subsequent Events

In January 1996,  NEBOH obtained a line of credit with a bank which provided for
borrowings of up to $300,000.  The line of credit is secured by certain accounts
receivable  of the  partnership.  The  proceeds  of the  line are to be used for
general operating expenses. The line bears interest at prime plus 3/4%.

14.  Merger

On December 6, 1995,  the Company signed a letter of intent to merge into Telor.
Under the terms of the merger, all of the outstanding shares of common stock and
convertible  preferred  stock of the Company at the effective date of the merger
will be converted into shares of Telor common stock, $.001 par value. All of the
outstanding warrants and options to purchase shares of Company common stock will
upon the merger become  warrants and options to purchase  shares of Telor common
stock.

Immediately after the consummation of the merger, the Company  stockholders will
hold or have the right to receive  upon  exercise of options or  warrants  fifty
percent (50%) of the outstanding shares of Telor stock on a fully diluted basis.
The  name  of  the  surviving   corporation   will  be  Occupational   Health  +
Rehabilitation  Inc. It is expected  that the merger will be accounted  for as a
reverse purchase and is intended to quality as a tax-free reorganization.

Equity Securities of OH+R held in

                                    A - 2

<PAGE>

OH+R's  treasury or by any OH+R  Subsidiary  and (ii) such Equity  Securities of
OH+R, if any, as may then be owned by Telor) shall be cancelled and converted in
the manner set forth below:

            (i) each  outstanding  share of OH+R Common Stock shall be converted
      into and exchanged for the right to receive from the Surviving Corporation
      the Share Conversion Fraction (as hereinafter defined) of a share of Telor
      Stock;

            (ii)  each  outstanding  share  of OH+R  Preferred  Stock  shall  be
      converted  into and  exchanged for the right to receive from the Surviving
      Corporation the number of shares of Telor Stock equal to (x) the number of
      shares of OH+R Common Stock then  receivable upon conversion of such share
      of OH+R Preferred Stock multiplied by (y) the Share Conversion Fraction;

            (iii) the NEB Note shall be  converted  into and  exchanged  for the
      right to  receive  from the  Surviving  Corporation  a number of shares of
      Telor  Stock  equal to (x) the  number  of  shares  of OH+R  Common  Stock
      receivable upon conversion  thereof multiplied by (b) the Share Conversion
      Fraction,  unless OH+R has  obtained the  agreement of the holder  thereof
      prior to the Closing  that the  conversion  right shall be  cancelled,  in
      which event the NEB Note shall remain outstanding; and

            (iv) the OH+R Employee Stock Options and the OH+R Warrants shall not
      be converted  into and  exchanged  for Telor Stock but shall be subject to
      the provisions of Section 1.10.

      (b) Share Conversion  Fraction.  The "Share Conversion  Fraction" shall be
calculated  as of the  Closing  Date by  dividing  (i) the sum of (A) the  total
number of shares  of Telor  Stock  outstanding  as of such  date,  (B) the total
number  of shares of Telor  Stock  issuable  upon  exercise  of all  outstanding
options to purchase Telor Stock (less any options  granted to directors who will
as of the  Effective  Time cease to be  directors  of Telor,  to the extent such
options will not be exercisable as of the Effective Time or thereafter)  and (C)
the total number of shares of Telor Stock, if any, issuable or transferable upon
the conversion, exchange and/or exercise of any Equity Securities (other than as
provided  in  clause  (B)  immediately  above)  by (ii) the sum of (A) the total
number of shares of OH+R Common Stock outstanding as of such date, (B) the total
number of shares of OH+R Common Stock  receivable  upon conversion of all shares
of OH+R  Preferred  Stock  outstanding  as of such date, (C) the total number of
shares of OH+R Common Stock  receivable  upon conversion of the NEB Note (unless
such  conversion  right has been  cancelled),  (D) the total number of shares of
OH+R Common Stock  issuable upon exercise of all OH+R Employee Stock Options and
OH+R Warrants  outstanding as of such date and (E) the total number of shares of
OH+R Stock,  if any,  issuable or  transferable  upon the  conversion,  exchange
and/or exercise of any Equity  Securities (other than as provided in clauses (B)
through (D) immediately above).

                                    A - 3

<PAGE>

      SECTION 1.08 Fractional  Shares. No fractional shares of Telor Stock shall
be issued,  but in lieu thereof each OH+R  Securityholder who would otherwise be
entitled to receive a fraction of a share of Telor Stock shall  receive from the
Surviving  Corporation  an amount of cash (rounded to the nearest cent) equal to
the per share  market  value of Telor  Stock  (based on the last sales  price of
Telor  Stock as  reported on the  National  Market  System of Nasdaq on the most
recent trading day prior to the date of the Closing)  multiplied by the fraction
of a share of Telor Stock to which such holder would otherwise be entitled.  The
fractional  share  interests of each OH+R  Securityholder  in each case shall be
aggregated so that no OH+R Securityholder  shall receive cash in an amount equal
to or greater than the per share market value of one full share of Telor Stock.

      SECTION  1.09  Stockholders  Approvals.  Telor shall hold a meeting of its
stockholders  (the "Telor  Stockholders  Meeting") to consider and vote upon the
approval of this Agreement and the Merger,  and OH+R shall hold a meeting of its
stockholders  or provide an action by written consent to its  stockholders  (the
"OH+R  Stockholders  Approval")  to consider  and vote upon the approval of this
Agreement  and the  Merger  contemplated  hereby,  all in  accordance  with  the
provisions of the DGCL,  as soon as  practicable  after Telor's proxy  statement
(the "Proxy  Statement")  relating to the Merger  shall have been cleared by the
Securities and Exchange  Commission (the "SEC"). The Telor Stockholders  Meeting
and the OH+R  Stockholders  Approval  shall  collectively  be referred to as the
"Stockholders Approvals."

      SECTION 1.10 Treatment of Employee Stock Options and OH+R Warrants.

            (a) Conversion of OH+R Employee Stock Options and OH+R Warrants.  At
the  Effective  Time  and  thereafter,  each  OH+R  Employee  Stock  Option  (in
accordance  with the terms of Section 10 of the OH+R Stock Plan and Section 9 of
each OH+R Employee  Stock Option  Agreement) and each OH+R Warrant shall entitle
the holder  thereof,  upon exercise in  accordance  with the terms  thereof,  to
acquire  (instead of OH+R Common  Stock)  Telor Stock in an amount  equal to the
number of shares of Telor Stock that would have been  distributable  pursuant to
the  Merger at the  Effective  Time in  respect  of the number of shares of OH+R
Common Stock  issuable upon exercise of such OH+R Employee  Stock Option or OH+R
Warrant  (assuming  that any vesting  requirements  applicable  thereto had been
satisfied prior to exercise) at an exercise price per share of Telor Stock equal
to the number  obtained by multiplying  (x) the exercise price per share of OH+R
Common  Stock under the terms of such  option or warrant by (y) a fraction,  the
numerator  of which is the number of shares of OH+R Common Stock  issuable  upon
exercise of such OH+R Employee Stock Option or OH+R Warrant immediately prior to
the Merger (assuming that any vesting  requirements  applicable thereto had been
satisfied  prior to  exercise)  and the  denominator  of which is the  number of
shares of Telor Stock issuable upon exercise of such option or warrant,  subject
in any  event to the other  terms and  conditions  of such OH+R  Employee  Stock
Option or OH+R Warrant, as the case may be. Any fractional shares of Telor Stock
to which the holder of any OH+R  Employee  Stock Option or OH+R Warrant would be
entitled  upon exercise  thereof shall be treated as provided in the  applicable
OH+R Stock Plan and OH+R Employee Stock Option Agreement or OH+R Warrant, as the
case may be.

                                    A - 4

<PAGE>

            (b) Vesting; No Amendments,  etc. Except for (i) options to purchase
1,210 shares of OH+R Common Stock held by consultants of OH+R,  which are on the
date hereof and shall remain fully vested,  (ii) options outstanding on the date
hereof to  purchase  300,000  shares of OH+R Common  Stock held by certain  OH+R
officers and holders of Common Stock,  of which 200,000 shares are subject to an
option granted to John C. Garbarino,  subject to the following vesting schedule:
100,000 shares  immediately prior to the Effective Time, 50,000 shares after one
year of employment by the Surviving  Corporation and an additional 50,000 shares
after  two  years of  employment,  provided  that  such  options  shall be fully
exercisable  upon a change of  control  or if his  employment  by the  Surviving
Corporation  shall be  terminated  without  cause,  and the  remainder  of which
options shall become  exercisable  in accordance  with their terms and (iii) the
OH+R Warrants,  which shall become fully exercisable  commencing on July 1, 1997
in accordance  with their current  terms,  OH+R Employee  Stock Options shall be
subject to a four year vesting  period,  vesting in equal  annual  installments,
which  vesting  period will  commence  upon the original  grant date of the OH+R
Employee Stock Options by OH+R. OH+R represents, warrants and agrees that it has
not and will not amend or modify  the terms of the OH+R  Stock  Plan or any OH+R
Employee Stock Option at any time through the Effective Time.

      SECTION 1.11 Cancellation of Treasury Stock and Stock held by Telor. As of
the Effective Time, each share of OH+R Common Stock and OH+R Preferred Stock (if
any) held by OH+R or by any OH+R  Subsidiary or by Telor shall, by virtue of the
Merger and without any further action on the part of OH+R,  any OH+R  Subsidiary
or Telor,  be  cancelled,  returned and cease to exist,  and no payment or other
distribution shall be made with respect thereto.

      SECTION 1.12 Tax-Free Reorganization. The Merger is intended to qualify as
a tax-free  reorganization  within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code").

      SECTION 1.13 Closing.  The closing of the Merger (the "Closing") will take
place as soon as practicable after the later of the date of (i) the Stockholders

      SECTION 1.15 Exchange of Certificates.

      (a) At the Closing  (provided that the  capitalization of neither OH+R nor

date  of  the  Closing),   certificates  representing  all  of  the  issued  and
outstanding  shares of OH+R  Common  Stock  and OH+R  Preferred  Stock  shall be
surrendered for  cancellation  and  termination in the Merger.  At the Effective
Time, each such certificate shall be cancelled,  and,  simultaneously  with such
cancellation,  a new  certificate  for shares of Telor Stock,  representing  the
number of shares of Telor Stock into which the shares of OH+R  Common  Stock and
OH+R Preferred Stock formerly  represented by such  certificate  shall have been
converted in the Merger, shall be issued to the holder thereof,  together with a
check payable to such holder representing  payment of cash in lieu of fractional
shares  determined  in accordance  with Section 1.08 hereof.  From and after the
Effective Time, each  certificate  which prior to the Effective Time represented
shares of OH+R Common Stock or OH+R Preferred Stock shall be deemed to represent
only the right to receive the  certificates  representing  shares of Telor Stock
and  cash  payment  under  Section  1.08,  if  applicable,  contemplated  by the
preceding sentence,  and the holder of each such certificate shall cease to have
any rights with  respect to the shares of OH+R Common  Stock and OH+R  Preferred
Stock formerly represented thereby.

      (b) If the  capitalization of either Telor or OH+R changes within the four
(4) business  days  immediately  preceding  the date of the Closing,  then State
Street Bank and Trust Company,  Telor's  transfer  agent,  shall act as exchange
agent (the "Exchange  Agent") in the Merger,  and the provisions of this Section
1.15 (c) through (g) shall apply.

      (c) As promptly as practicable after the Effective Time of the Merger (but
in no event later than ten (10) days after the  Effective  Time of the  Merger),
Telor shall make  available for exchange in  accordance  with this Section 1.15,
through such reasonable procedures as Telor may adopt, the shares of Telor Stock
issuable pursuant to Section 1.07.

      (d) As promptly as practicable after the Effective Time of the Merger (but
in no event later than ten (10) days after the  Effective  Time of the  Merger),
the  Exchange  Agent  shall  mail or  deliver  to each  holder  of  record  of a
certificate or certificates which immediately prior to the Effective Time of the
Merger represented  outstanding shares of OH+R Stock (the "Certificates")  whose
shares were  converted into the right to receive Telor Stock pursuant to Section
1.07 hereof and the  Certificate of Merger,  (i) a letter of transmittal  (which
shall specify that delivery shall be effected,  and risk,  loss and title to the
Certificates  shall pass, only upon delivery of the Certificates to the Exchange
Agent  and shall be in such form and have  such  other  provisions  as Telor may
reasonably  specify) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for a certificate  representing  Telor Stock.  Upon
surrender of a Certificate  for  cancellation  to the Exchange  Agent or to such
other agent or agents as may be

                                    A - 7

<PAGE>

appointed by Telor,  together with such letter of  transmittal,  duly  executed,
such agent shall promptly deliver in accordance with the  instructions  properly
contained  in such letter of  transmittal  (i) a  certificate  for the number of
shares of Telor Stock to which such holder is entitled  pursuant to Section 1.07
and (ii) a check in the  amount  due  such  holder  for the  value  computed  in
accordance  with  Section  1.08  (and  without  any  interest  thereon)  of  any
fractional share interest such holder may have.

      (e) Any  Certificate  surrendered  in  accordance  with this Section shall
forthwith  be  cancelled.  In the event of a transfer of  ownership of shares of
OH+R  Stock  which is not  registered  on the  transfer  records  of  OH+R,  the
appropriate  number of shares of Telor Stock may be delivered to a transferee if
the  Certificate  representing  such  shares of OH+R Stock is  presented  to the
Exchange Agent and accompanied by all documents  required to evidence and effect
such transfer and to evidence that any applicable stock transfer taxes have been
paid.  Until  surrendered as contemplated by this Section 1.15, each Certificate
shall, at any time after the Effective Time, represent the right to receive upon
such  surrender  the number of shares of Telor Stock as provided by this Section
1.15 and the provisions of the DGCL.

      (f) No holder of a  Certificate  shall be entitled to receive any dividend
or other  distribution from Telor with respect to the shares of Telor Stock such
holder is entitled to receive upon the surrender in accordance with this Section
1.15 of such  Certificate  until such  Certificate is so surrendered.  Upon such
surrender  there  shall  be  paid  without  interest,  in  accordance  with  the
instructions  properly  contained  in the duly  executed  letter of  transmittal
accompanying such surrender, with respect to the number of whole shares of Telor
Stock represented by the certificate or certificates issued upon such surrender:
(i) promptly,  the amount of any dividends or other distributions,  if any, that
theretofore became payable and (ii) at the appropriate  payment date, the amount
of dividends or other  distributions,  if any,  with (x) a record date after the
Effective  Time but prior to such  surrender  and (y) a payment  date  occurring
after such surrender.

      (g) All Telor Stock which shall have been  delivered upon or in connection
with the surrender for exchange of  Certificates in accordance with the terms of
this Section 1.15 including,  without limitation, of subsection (a) above, shall
be deemed to have been delivered in full  satisfaction of all rights  pertaining
to the shares of OH+R Common Stock and OH+R Preferred Stock  represented by such
Certificates. After the Effective Time there shall be no further registration of
transfers on the stock transfer books of the Surviving Corporation of the shares
of  capital  stock  of OH+R  which  were  outstanding  immediately  prior to the
Effective Time. If certificates  are presented to the Surviving  Corporation for
any reason,  they shall be cancelled  and  exchanged as provided in this Section
1.15.

      SECTION 1.16 Additional Issuances of Telor Stock.

      (a) Required  Additional  Issuances  of Telor Stock.  Reference is made to
that certain Standard Form Industrial Lease, dated July 12, 1994, by and between
WRC Properties,  Inc. (the "Landlord") and Telor (the "Lease"),  relating to the
lease by Telor of a portion of the property  located at 265 Ballardvale  Street,
Wilmington, Massachusetts (the "Premises") and to those

                                    A - 8

<PAGE>

certain  Letters  of  Credit,  in the  original  aggregate  amount of  $400,000,
securing Telor's  obligations under the Lease (the "Letters of Credit").  In the
event that there are Aggregate  Lease Payments (as defined below) at any time on
or after January 1, 1997 and prior to five years after the Commencement Date (as
defined in the Lease),  then the Surviving  Corporation  shall issue to the OH+R
Securityholders  (including  the  holder of the NEB Note only if the NEB Note is
converted in the Merger),  additional  shares of Telor Stock in accordance  with
the provisions of this Section 1.16. As used herein,  "Aggregate Lease Payments"
shall  mean the sum of (i) any  payments  by the  Surviving  Corporation  to the
Landlord on account of the Lease,  whether such  payments are rent or additional
rent payments  under the Lease or as settlement  payments in  termination of the
Lease or in connection  with  entering into a sublease or subleases,  including,
without  limitation,  as a result of any draw by the  Landlord on the Letters of
Credit,  (ii)  any  additional  costs  paid  by  the  Surviving  Corporation  in
connection  with the Premises  including,  without  limitation for heat or other
utilities and taxes but not including any costs  associated  with  violations or
alleged  violations of  Environmental  Laws,  (iii) any payment by the Surviving
Corporation  to any leasing agent in  connection  with the  termination  of such
Lease or the leasing of the  Premises to a subtenant or  subtenants  and (iv) at
such time as such payments are due to the Surviving Corporation,  any amount due
to the Surviving Corporation from a sublessee or subtenant of the Premises which
has not been  paid less the sum of (y) any  amounts  received  by the  Surviving
Corporation  from any  sublessee or subtenant of the Premises and (z) the amount
by which the Letters of Credit have been decreased  other than by payment to the
Landlord  either  pursuant  to the  provisions  of the Lease or as a result of a
sublessee or subtenant providing a replacement letter of credit to secure all or
a portion of the  obligations  under the Lease or  otherwise,  provided that all
amounts paid by the Surviving  Corporation  in connection  with entering into an
agreement with a subtenant or sublessee,  including, without limitation, leasing
agent fees and costs of  leasehold  improvements,  shall,  for  purposes of this
Section  1.16, be accounted  for by  amortizing  such payments  monthly over the
shorter of the term of the  applicable  subtenancy  or sublease or through  five
years after the Commencement Date,  whichever is shorter, and treated as paid on
a pro rata basis during such period.  Aggregate Lease Payments shall not include
payments due and any additional  costs in connection  with the Premises for heat
or other utilities payable under the Lease during 1996 or after five years after
the Commencement Date.

      (b) Number of Additional Shares.  Within thirty (30) days after the end of
the first calendar quarter in which the Aggregate Lease Payments exceed zero and
after the end of each calendar  quarter  thereafter in which the Aggregate Lease
Payments for which no adjustment has been made exceed zero (the last day of each
such calendar  quarter being a "Determination  Date"),  there shall be issued to
the OH+R  Securityholders  that number of additional  shares of Telor Stock,  if
any,  determined by  multiplying  (i) the Aggregate  Lease Payments for which no
adjustment has been made by .50 and (ii) dividing the amount obtained thereby by
seven  dollars  ($7)  (which  number  seven (7) shall be  subject  to  equitable
adjustment in the event of any stock split, stock dividend, reverse stock split,
or combination of the shares of Telor Stock). In addition, if there is a written
assertion of a violation of Environmental  Laws at the premises leased under the
Lease,  which written assertion is received by the Surviving  Corporation at any
time prior to the termination of the Lease,  but in any event no later than five
(5) years  after the  Commencement  Date (as  defined  in the  Lease),  and such
assertion is directly as a result of

                                    A - 9

<PAGE>

Telor's own  operations  (and not solely as a result of its  tenancy),  then, at
such  time as  there  has been a final,  non-appealable  judgment  by a court of
competent  jurisdiction or a binding  settlement  agreement among all parties in
interest with respect to such assertion  resulting in liability to the Surviving
Corporation,  there shall be issued to the OH+R  Securityholders  that number of
additional shares of Telor Stock determined by multiplying (i) the actual amount
of costs  incurred by the Surviving  Corporation as a result of such judgment or
settlement  as  reduced  by any  funds to which  the  Surviving  Corporation  is
entitled in connection with such liability (including,  without limitation,  any
insurance  proceeds),  by .50 and (ii) dividing the amount  obtained  thereby by
seven  dollars  ($7)  (which  number  seven (7) shall be  subject  to  equitable
adjustment in the event of any stock split, stock dividend, reverse stock split,
or  combination  of the shares of Telor Stock).  All shares of Telor Stock which
may be issued to the OH+R  Securityholders  pursuant  to this  Section  1.16 are
hereinafter  referred to as "Additional  Shares." After the  consummation of the
Merger,  the  provisions  of this Section 1.16 may be waived or amended with the
consent of the Surviving Corporation and the OH+R Securityholders which hold (or
upon  exercise of OH+R  Options and OH+R  Warrants  would  hold,  regardless  of
whether  such OH+R  Options  and OH+R  Warrants  are  currently  exercisable)  a
majority  of that  number of shares as equals the sum of the number of shares of
Telor  Stock  issued in the Merger and the shares of Telor Stock  issuable  upon
exercise of the OH+R Options and OH+R Warrants.

      (c) Allocation Among OH+R Securityholders.  The Additional Shares shall be
allocated  among  the  OH+R  Securityholders  pro rata  based on their  relative
ownership  interest  in OH+R as of  immediately  prior  to the  Effective  Time,
assuming for such purpose the conversion of all shares of OH+R Preferred  Stock,
the conversion of the NEB Note (if converted in the Merger), and the exercise of
all OH+R Employee  Stock  Options and all OH+R  Warrants.  No fractional  shares
shall be issued,  and the provisions of Section 1.08 shall apply with respect to
fractional  shares  except that the  reference  to the "date of  Closing"  shall
become a reference to the applicable "Determination Date."

      (d) Special Provisions  Relative to Holders of OH+R Employee Stock Options
and/or OH+R Warrants.  With respect to each OH+R Securityholder that is a holder
of OH+R Employee Stock Options and/or OH+R Warrants,

            (i)  the  number  of  Additional   Shares  allocated  to  such  OH+R
      Securityholder   shall   be   allocated   pro   rata   among   such   OH+R
      Securityholder's  holdings of shares of OH+R Common Stock,  OH+R Preferred
      Stock (on an as converted basis),  OH+R Employee Stock Options and/or OH+R
      Warrants as of  immediately  prior to the Effective  Time,  subject to the
      following clauses (ii) through (v);

            (ii)  the  number  of  Additional  Shares  allocated  to  such  OH+R
      Securityholder's OH+R Employee Stock Options shall be allocated among such
      options in an equitable  manner so as to preserve the vesting  schedule of
      such options;

            (iii) if an OH+R Employee  Stock Option or OH+R Warrant held by such
      OH+R  Securityholder  has  been  exercised  in full  as of the  applicable
      Determination Date,

                                    A - 10

<PAGE>

      the Additional Shares allocated to such OH+R Employee Stock Option or OH+R
      Warrant,  as the case may be, on a  Determination  Date shall be issued to
      such OH+R Securityholder;

            (iv) if an OH+R  Employee  Stock Option or OH+R Warrant held by such
      OH+R   Securityholder   has  not  been  exercised  as  of  the  applicable
      Determination Date, the number of Additional Shares allocated to such OH+R
      Employee  Stock  Option  or OH+R  Warrant,  as the  case  may be,  on such
      Determination  Date shall be added to the number of shares of Telor  Stock
      issuable upon exercise of such OH+R Employee Stock Option or OH+R Warrant,
      as the case may be, as a result of the Merger, as provided in Section 1.10
      of this  Agreement,  and the  exercise  price  per  share of  Telor  Stock
      pursuant to such OH+R Employee  Stock Option or OH+R Warrant,  as the case
      may be, shall be adjusted such that the aggregate  exercise  price of such
      OH+R  Employee  Stock  Option or OH+R  Warrant,  as the case may be, shall
      remain the same as of immediately prior to such adjustment; and

            (v) if only a  portion  of an OH+R  Employee  Stock  Option  or OH+R
      Warrant  held by such OH+R  Securityholder  has been  exercised  as of the
      applicable   Determination  Date,  a  portion  of  the  Additional  Shares
      allocated to such OH+R Employee Stock Option or OH+R Warrant,  as the case
      may be,  shall be issued to the OH+R  Securityholder  as provided in (iii)
      above and a portion of the Additional  Shares shall be added to the number
      of shares of Telor Stock  issuable  upon  exercise  thereof as provided in
      (iv) above,  such portions to be determined based on the percentage of the
      OH+R Employee Stock Option or OH+R Warrant,  as the case may be, which has
      been exercised.

      (e) Restrictions on Additional  Shares.  The Surviving  Corporation  shall
issue the Additional  Shares to be issued to the OH+R  Securityholders,  if any,
within thirty (30) days of the applicable Determination Date; provided, that the
Surviving  Corporation may delay issuance of such shares until completion of any
action or  obtaining  of any  consent  which  the  Surviving  Corporation  deems
necessary under applicable law (including, without limitation, federal and state
securities  laws);  and without  limiting the generality of the  foregoing,  the
Surviving   Corporation   may  delay   issuance  of  such  shares  to  any  OH+R
Securityholder  until such time as such OH+R  Securityholder has made investment
representations  substantially  similar  to those  set  forth in the  Investment
Letter set forth at Exhibit 6.21 of this  Agreement.  The Surviving  Corporation
shall not be obligated to register the issuance of the  Additional  Shares under
the  Securities  Act.  The holders of  Additional  Shares will be subject to the
rights and obligations of the Registration Rights Agreement with respect to such
Additional  Shares,  which rights and obligations shall be commensurate with the
rights of the holders of the Equity  Securities of OH+R to which such Additional
Shares were allocated as provided above in this Section.

              ARTICLE II  REPRESENTATIONS AND WARRANTIES OF OH+R

      As an inducement  to Telor to enter into this  Agreement and to consummate
the transactions contemplated hereby, OH+R hereby represents and warrants to and
agrees with Telor as follows:

      SECTION  2.01  Capitalization.  The  authorized,  issued  and  outstanding
capital  stock of OH+R  consists on the date hereof,  and will at the  Effective
Time consist solely of (subject only to changes resulting from the conversion of
the NEB Note or as  permitted  by Section  4.07),  1,600,000  shares of Series 1
Preferred  Stock,  $.01 par  value,  of which  1,600,000  shares  are issued and
outstanding and owned by the OH+R  Securityholders free and clear of all Claims,
as set forth on Schedule  2.01,  3,000,000  shares of Series 2 Preferred  Stock,
$.01 par value, of which  2,537,843  shares are issued and outstanding and owned
by the OH+R  Securityholders,  free and clear of all Claims  (except as noted on
Schedule  2.01),  as set forth on Schedule 2.01, and 8,000,000  shares of common
stock,  $.01 par value  per  share,  of which  671,855  shares  are  issued  and
outstanding and owned by the OH+R Securityholders,  free and clear of all Claims
as set forth on Schedule 2.01, in each case with no personal liability attaching
to the  ownership  thereof.  All of such  shares  are duly  authorized,  validly
issued,  fully paid and  non-assessable  and were issued in full compliance with
all federal,  state and local rules,  laws and  regulations.  The  designations,
powers,  preferences,  rights,  qualifications,  limitations and restrictions in
respect of each class and series of authorized  capital stock of OH+R are as set
forth in OH+R's  Certificate  of  Incorporation,  as  amended,  a  complete  and
accurate  copy of which has been provided to Telor,  and all such  designations,
powers, preferences,  rights,  qualifications,  limitations and restrictions are
valid,  binding and  enforceable in accordance with all applicable  laws.  There
are, and at the  Effective  Time there will be (subject  only to such changes as
are permitted by Section 4.07), no shares held in the corporate treasury of OH+R
and no shares  reserved for issuance,  except as set forth on Schedule  2.01. To
the  knowledge  of OH+R,  none of the  OH+R  Securityholders  is an  "Interested
Stockholder," as such term is defined in Telor's  Certificate of  Incorporation,
as amended and restated as of the date  hereof,  or as defined in Section 203 of
the DGCL.  Except as set forth on Schedule 2.01 and as permitted by Section 4.07
of this Agreement, as of the date hereof there are, and as of the Effective Time
there will be (subject only to such changes as are  permitted by Section  4.07),
no outstanding  subscriptions,  options,  warrants, rights, calls or convertible
securities,  stock  appreciation  rights (phantom or otherwise),  joint venture,
partnership or other commitments of any nature relating to shares of the capital
stock of OH+R.  Except  as set forth in its  Certificate  of  Incorporation,  as
amended,  and on Schedule  2.01,  as of the date hereof there is, and, as of the
Effective Time OH+R will have, no obligation  (contingent or other) to purchase,
redeem or otherwise acquire any of its equity securities or any interest therein
or to pay any dividend or make any other distribution in respect thereof. Except
as set forth on Schedule 2.01, none of OH+R's  outstanding  Equity Securities or
authorized  capital stock are subject to any rights of  redemption,  repurchase,
rights of first refusal, preemptive rights, registration rights or other similar
rights,  whether contractual,  statutory or otherwise,  for the benefit of OH+R,
any OH+R  Securityholder  or any other  Person.  Except as set forth on Schedule
2.01, there are no restrictions on the transfer of shares

                                    A - 12

of capital stock of OH+R other than those imposed by relevant  federal and state
securities laws and as otherwise contemplated by this Agreement.

      SECTION 2.02 Organization and Qualification. Each of OH+R and Occupational
Health  Physicians,  Inc.  ("OHP")  is a  corporation  duly  organized,  validly
existing  and in  good  standing  under  the  laws  of the  jurisdiction  of its
incorporation  and is duly  licensed  or  qualified  to  transact  business as a
foreign  corporation  and is in good  standing  in each  jurisdiction  listed on
Schedule 2.02,  such  jurisdictions  being the only  jurisdictions  in which the
nature of OH+R's, or to OH+R's knowledge, OHP's business or the character of the
properties   owned  or  leased  by  OH+R  or  OHP  requires  such  licensing  or
qualification.

      SECTION 2.03  Subsidiaries.  Each Subsidiary of OH+R is listed on Schedule
3.03 (such  Subsidiaries are sometimes referred to herein,  individually,  as an
"OH+R Subsidiary" and,  collectively,  as the "OH+R Subsidiaries";  OH+R and the
OH+R Subsidiaries are sometimes  referred to herein,  individually,  as an "OH+R

Company under any law, rule, regulation,  judgment,  decree, order, governmental

      SECTION 2.06 Financial Statements. OH+R has previously furnished to Telor,
and attached hereto as Schedule 2.06 are, the consolidated balance sheets of the
OH+R Companies as at December 31, 1995 (the "Balance  Sheet") and as at December
31,  1994 and the  related  statements  of  operations  and cash flows and notes
thereto for the fiscal years ended  December 31,  1995,  December 31, 1994,  and
December 31, 1993. All such financial  statements (the  "Financial  Statements")
have been prepared in accordance with generally accepted  accounting  principles
consistently applied (with the exception,  as of the date hereof, of the lack of
notes thereto for the  Financial  Statements at and as of December 31, 1995) and
were prepared from the books and records of the OH+R Companies,  which books and
records are complete and correct in all material respects and accurately reflect
all transactions of the OH+R

                                    A - 14

<PAGE>

Companies'  businesses.  The Financial  Statements  fairly present the financial
position of the OH+R Companies as of the dates thereof, and the results of their
operations  and cash  flows  for the  periods  ended on the dates  thereof.  The
Financial  Statements  reflect  reserves  appropriate and adequate for all known
material liabilities and reasonably  anticipated losses as required by generally
accepted accounting  principles.  OH+R has disclosed to Telor all material facts
relating to the preparation of the Financial Statements,  including the basis of
accounting for affiliated transactions, and OH+R has delivered to Telor complete
and correct copies of all letters of  representation  from OH+R delivered to its
accountants in connection with the preparation of such Financial Statements, and
all management letters from the accountants to OH+R.

      SECTION  2.07  Absence of  Undisclosed  Liabilities.  Except as and to the
extent of the amounts specifically  reflected or reserved against in the Balance
Sheet and as set forth on Schedule 2.07, no OH+R Company has any  liabilities or
obligations of any nature whatsoever,  due or to become due, accrued,  absolute,
contingent or otherwise  except for liabilities  and obligations  incurred since
the date of the Balance Sheet in the ordinary  course of business and consistent
with past  practice.  OH+R does not know of,  and has no reason to know of,  any
basis  for  the  assertion  against  the  OH+R  Companies  of any  liability  or
obligation  not fully  reflected  or reserved  against in the  Balance  Sheet or
incurred in the ordinary  course of business and  consistent  with past practice
since the date thereof. No OH+R Company is bound by any agreement, or subject to
any charter or other corporate restriction or any legal requirement,  which has,
or in the future can  reasonably be expected to have, a material  adverse effect
on the business of the OH+R Companies taken as a whole.

      SECTION 2.08 Absence of Adverse Change; Conduct of Business. Except as set
forth on Schedule 2.08 or in the notes to the  financial  statements of the OH+R
Companies as of and for the period ended  December 31, 1994,  since December 31,
1994,  each OH+R Company has conducted its business only in the ordinary  course
of business consistent with past practice. Except as set forth on Schedule 2.08,
since  December  31,  1994,  there has been no  material  adverse  change in the
business of the OH+R Companies and there is no known condition or development or
contingency of any kind existing or which,  so far as reasonably can be foreseen
by OH+R, may result in any such change.  Without limiting the foregoing,  except
as set forth on Schedule  2.08, in the notes to the financial  statements of the
OH+R  Companies as of and for the period ended  December 31, 1994,  or permitted
pursuant to Section 4.07, since December 31, 1994, there has not been,  occurred

Sheet in the ordinary course of business consistent with past practice;

      (n) any  waiver  by any OH+R  Company  of any  right or  rights  (alleged,

respect to all other employees, were not in excess of an average of 5% per annum

                                    A - 17

<PAGE>

      (w) any other event or condition  materially  and adversely  affecting the
properties, assets or business of any OH+R Company; or

      (x) any  understanding  entered into since December 31, 1994, with respect
to any commitment (contingent or otherwise) to do any of the foregoing.

      SECTION 2.09  Supplies.  All of the OH+R  Companies'  supplies  consist of
items  of a  quality  usable  in the  ordinary  course  of the  OH+R  Companies'
businesses as first quality goods. The OH+R Companies'  supplies are on the date
hereof, and will be at the Effective Time, at normal and adequate levels for the
continuation of their  businesses in the ordinary course of business  consistent
with past practice.

      SECTION 2.10  Receivables.  All receivables  (whether  notes,  accounts or
otherwise)  of  the  OH+R   Companies  (a)  have  arisen  only  from  bona  fide
transactions in the ordinary  course of business  consistent with past practice,
(b)  represent  valid  obligations,  and (c)  shall  be fully  collected  in the
aggregate  face  amounts  thereof  within a  reasonable  time after the issuance
thereof, except to the extent of the normal allowance for doubtful accounts with
respect to accounts  receivable  computed in a manner  consistent with generally
accepted  accounting  principles and as reflected in the Balance Sheet,  and (d)
are  owned by the OH+R  Companies  free of all  Claims,  except  as set forth on
Schedule  2.10. No discount or allowance  from any  receivable  has been made or
agreed to (other than  contingency  payment  discounts in the ordinary course of
business  consistent with past practice),  and none represents billings prior to
actual sale of goods or provision of services.

      SECTION  2.11 Taxes.  Each OH+R  Company  has filed on a timely  basis all
returns,  declarations,  reports,  claims for refunds and information returns or
statements  relating to all taxes including,  without  limitation,  any federal,
state, local, or foreign income, gross receipts,  license, payroll,  employment,
excise, severance, stamp, occupation,  premium, windfall profits,  environmental
(including taxes under Code Sec. 59A), customs duties,  capital stock franchise,
profits, withholding,  social security (or similar),  unemployment,  disability,
real property,  personal  property,  sales, use, transfer,  registration,  value
added,  alternative  or  add-on  minimum,  estimated,  or other  tax of any kind
whatsoever,  including  any  interest,  penalty,  or addition  thereto,  whether
disputed or not (collectively,  "Taxes"), including all schedules or attachments
thereto,  and including any  amendment  thereof ("Tax  Returns") and tax reports
required  to be  filed  on or  before  the  date  hereof  with  the  appropriate
governmental agencies in all jurisdictions in which such returns and reports are
required to be filed,  and all such Tax Returns were correct and complete in all
material respects.  All Taxes which have become due or payable or required to be
collected  by each OH+R  Company or as  otherwise  attributable  to any  periods
ending on or before the date hereof or the  Effective  Time and all interest and
penalties  thereon,  whether  disputed or not, have been paid or will be paid in
full on or prior to the Effective Time (whether or not shown on any Tax Return).

      No OH+R  Company is currently  the  beneficiary  of any  extension of time
within which to file any Tax Return. No claim has been made by an authority in a
jurisdiction  where any OH+R Company does not file Tax Returns that it is or may
be subject to taxation by that

                                    A - 18

<PAGE>

jurisdiction. There are no tax liens pending or, to OH+R's knowledge, threatened
against the assets,  properties or business of any OH+R Company. No OH+R Company
has taken or failed to take any action which could create any tax lien on any of
its assets.

      Each OH+R Company has  withheld  and paid all Taxes  required to have been
withheld and paid in  connection  with  amounts  paid or owing to any  employee,
creditor, independent contractor or other third party.

      OH+R does not expect any authority to assess any additional  Taxes for any
period  for which Tax  Returns  have been  filed.  There is no  dispute or claim
concerning  any  liability,  whether  known  or  unknown,  whether  assessed  or
unassessed,  whether accrued or unaccrued, and whether due or to become due (the
"Tax  Liability")  of any OH+R  Company  either  (A)  claimed  or  raised by any
authority in writing or (B) as to which OH+R has knowledge.  Schedule 2.11 lists
all federal,  state,  local and foreign income tax returns filed with respect to
the OH+R  Companies  for taxable  periods  ended on or after  December 31, 1992,
indicates  those tax returns that have been  audited,  and  indicates  those tax
returns that  currently  are the subject of audit.  OH+R has  delivered to Telor
correct  and  complete  copies of all  federal  and state  income  tax  returns,
examination reports,  and statements of deficiencies  assessed against or agreed
to by any OH+R Company  since  December 31,  1992.  Schedule  2.11 lists all tax
agreements  which now exist or have existed  within the past five years  between
any OH+R  Company and any taxing  jurisdiction.  No OH+R  Company has waived any
statute of  limitations  in respect of Taxes or agreed to any  extension of time
with respect to a tax assessment or deficiency.

      No OH+R  Company  has filed a consent  under Code Sec.  341(f)  concerning
collapsible corporations. No OH+R Company has made any payments, is obligated to
make  any  payments,  or  is  a  party  to  any  agreement  that  under  certain
circumstances could obligate it to make any payments that will not be deductible
under Code Sec.  280G.  No OH+R Company has been a United  States real  property
holding  corporation  within  the  meaning  of Code Sec.  897(c)(2)  during  the
applicable period specified in Code Sec. 897(c)(1)(A)(ii). Each OH+R Company has
disclosed on its federal  income Tax Returns all  positions  taken  therein that
could give rise to a substantial understatement of federal income tax within the
meaning of Code Sec.  6661. No OH+R Company is a party to any tax  allocation or
sharing  agreement.  Except  for being a member of the OH+R  Companies,  no OH+R
Company has ever been (nor has any  liability  for unpaid Taxes  because it once
was) a member of an affiliated  group. No OH+R Company has any Tax Liability for
the Taxes of any person (other than any of the OH+R Companies) under Treas. Reg.
ss.1.1502-6  (or any similar  provision of state,  local,  or foreign  law),  as
transferee or successor, by contract, or otherwise.

      SECTION 2.12 Litigation. Except as set forth on Schedule 2.12, there is no
(a) action,  suit,  claim,  proceeding  or  investigation  pending or, to OH+R's
knowledge, threatened against or affecting any OH+R Company (whether or not such
OH+R Company is a party or prospective  party thereto) or any officer,  director
or employee of any OH+R Company (which, with respect to any person who is not an
officer or director  of any OH+R  Company,  shall be limited to actions,  suits,
claims, proceedings or investigations against or affecting such persons in their
capacity as employees), at law or in equity, or before or by any

                                    A - 19

<PAGE>

federal, state, municipal or other governmental department,  commission,  board,
bureau,  agency  or  instrumentality,   domestic  or  foreign,  (b)  arbitration
proceeding relating to any OH+R Company or any officer,  director or employee of
any OH+R  Company  (which,  with  respect to any person who is not an officer or
director  of any OH+R  Company,  shall be limited  to  actions,  suits,  claims,
proceedings  or  investigations  against  or  affecting  such  persons  in their
capacity  as  employees)  or (c)  governmental  inquiry  pending  or  threatened
against,  involving  or affecting  any OH+R Company or any officer,  director or
employee of any OH+R  Company  (which,  with respect to any person who is not an
officer or director  of any OH+R  Company,  shall be limited to actions,  suits,
claims, proceedings or investigations against or affecting such persons in their
capacity as employees).  To the knowledge of OH+R, no officer or director of any
OH+R Company would be unable to give the representation  that none of the events
or  circumstances  described in Rule 262 of Regulation A  promulgated  under the
Securities  Act have  occurred.  No OH+R  Company  has  received  any opinion or
memorandum or advice from legal counsel to the effect that it is exposed, from a
legal standpoint,  to any liability or disadvantage which may be material to the
business, prospects, financial condition, operations, property or affairs of its
business.  There are no outstanding  orders,  writs,  judgments,  injunctions or
decrees of any  court,  governmental  agency or  arbitration  tribunal  against,
involving or affecting any OH+R Company, and, to OH+R's knowledge,  there are no
facts or  circumstances  now in existence which  reasonably could be expected to
result in institution of any action,  suit,  claim or legal,  administrative  or
arbitration proceeding or investigation against, involving or affecting any OH+R
Company or the  transactions  contemplated  hereby that  individually  or in the
aggregate  would have a material  adverse  effect upon the OH+R Companies or the
transactions  contemplated hereby. No OH+R Company is in default with respect to
any order, writ,  injunction or decree known to or served upon it from any court
or  of  any  federal,   state,  municipal  or  other  governmental   department,
commission, board, bureau, agency or instrumentality, domestic or foreign. There
is no action or suit by any OH+R Company pending or threatened against others.

      SECTION  2.13 Certain  Practices.  Neither any OH+R Company nor any of its
directors, officers or employees has, directly or indirectly, given or agreed to
give any significant rebate, gift or similar benefit to any supplier,  customer,
governmental  employee  or other  person who was,  is or may be in a position to
help or hinder the OH+R  Companies (or assist in  connection  with any actual or
proposed  transaction)  which (i) could subject any OH+R Company or Telor to any
damage  or  penalty  in  any  civil,  criminal  or  governmental  litigation  or
proceeding, or (ii) if not continued in the future, could have an adverse effect
on the OH+R Companies or Telor.

      SECTION 2.14 Compliance with Law.

      (a) General.  No OH+R  Company is subject to any  judgment,  order,  writ,
injunction,  or decree  that  affects,  individually  or in the  aggregate,  its
businesses,   operations,   properties,   assets  or  condition   (financial  or
otherwise). Each OH+R Company has complied with and is not in default under, all
laws, ordinances,  legal requirements,  rules, regulations and orders applicable
to it, its operations,  properties,  assets, products and services.  There is no
existing law, rule,  regulation or order,  and OH+R is not aware of any proposed
law, rule, regulation

                                    A - 20

or order,  whether federal or state, which would prohibit or materially restrict
any OH+R  Company or,  after the Merger,  the  Surviving  Corporation  from,  or
otherwise materially adversely affect any OH+R Company or, after the Merger, the
Surviving  Corporation  in,  conducting  the business of any OH+R Company in any
jurisdiction  in  which  such  business  is  now  conducted  or  proposed  to be
conducted.

      (b) Specific Laws.  Notwithstanding the generality of the other provisions
hereof,  (i) each OH+R  Company  and the conduct of its  business  as  presently
conducted  and as proposed to be  conducted  is and will be in  compliance  with
applicable  provisions of the federal Medicare and Medicaid statutes,  state law

offering,  receipt or payment of any remuneration,  in cash or in kind, directly

and (v) any Person  retained by any OH+R  Company  (whether on an  intermittent,
temporary or permanent  basis) who is required to have any individual  training,
certification,  permit or  license  to  provide or  supervise  any  services  in
connection with the business of the OH+R Companies as presently  conducted or as
currently   proposed  to  be   conducted   has  all  such   required   training,
certifications, permits and licenses.

      SECTION  2.15  Licenses  and Permits.  Schedule  2.15 lists all  licenses,
permits, pending applications, consents, approvals and authorizations of or from
any public or governmental agency, including,  without limitation, any boards of
medicine  (collectively,  the "Permits"),  used in or otherwise necessary in the
conduct of the business of each OH+R Company,  each of which will remain in full
force and effect  following the execution and delivery of this Agreement and the
consummation of the Merger and the other  transactions  contemplated  hereby.  A
description  of the Permits of the OH+R Companies is set forth on Schedule 2.15,
including the agency or other  governmental body issuing such permits,  licenses
and  authorizations,   the  expiration  date  of  such  permits,   licenses  and
authorizations,  the process by which each permit, license and authorization may
be renewed and, to OH+R's knowledge,  the likelihood of such renewal.  Each OH+R
Company  has  complied  with all  conditions  and  requirements  imposed  by the
Permits,  and OH+R has not  received  any notice of, nor has reason to  believe,
that any appropriate authority intends to cancel or terminate any of the Permits
or that valid  grounds for such  cancellation  or  termination  exist.  No other
permits, licenses or authorizations are necessary to operate the business of any
OH+R  Company.  Each OH+R  Company  owns or has the right to use its  Permits in
accordance  with the terms thereof  without any conflict or alleged  conflict or
infringement  with the rights of others and subject to no Claim, and each Permit
is valid and in full force and effect,  and will not be  terminated or adversely
affected by the transactions contemplated hereby.

      SECTION 2.16 Labor and Employee  Relations.  No OH+R Company is a party to
or bound by any collective  bargaining  agreement  with any labor  organization,
group or association covering any of its employees, and OH+R has no knowledge of
any attempt to organize any of the  employees of any OH+R Company by any person,
unit or group seeking to act as their bargaining  agent.  Except as set forth on
Schedule 2.16, there are no pending or threatened  charges (by employees,  their
representatives  or  governmental  authorities)  of unfair labor practices or of
employment  discrimination  or of any other wrongful  action with respect to any
aspect of  employment  of any person  employed or formerly  employed by any OH+R
Company,  and,  to the  knowledge  of OH+R,  there are no  grounds  for any such
charges.  No union  representation  elections  relating to employees of any OH+R
Company  have  been  scheduled  by any  governmental  agency  or  authority,  no
organizational  effort is being made with respect to any of such employees,  and
there is no investigation of any OH+R Company's employment policies or practices
by any governmental  agency or authority pending or threatened.  No OH+R Company
is  currently,  and has not within the last three years been,  involved in labor
negotiations  with any unit or group seeking to become the  bargaining  unit for
any employees of the OH+R  Companies.  No OH+R Company has  experienced any work
stoppages during the last three years, and to OH+R's knowledge, no work stoppage
is planned.

      SECTION 2.17 Employees.  Set forth in Schedule 2.17 is a list of the names
of all employees and consultants of the OH+R Companies,  together with the title
or job  classification  of each such  person  and the base  annual and the total
compensation  to be paid to each such person in fiscal year 1995 and anticipated
to be paid in fiscal year 1996.  Except as  specifically  described  on Schedule
2.17, none of such persons has an employment agreement or understanding, whether
oral or written, with any OH+R Company which is not terminable on notice by such
OH+R Company  without cost or other  liability to such OH+R  Company.  No person
listed on Schedule 2.17 has indicated that he or she intends to terminate his or
her  employment  with any OH+R  Company or seek a material  change in his or her
duties or status.

      SECTION 2.18 Employee Benefits.

      (a)  Employee  Benefit  Plans.  Schedule  2.18(a)  contains a complete and
correct list of each "employee  benefit plan" (as defined in Section 3(3) of the
Employment  Retirement Income Security Act of 1974, as amended ("ERISA")) of the
OH+R  Companies  and each other  plan,  program  or  arrangement  providing  for
pension,  profit sharing,  retirement,  deferred  compensation,  stock purchase,
stock   option,    incentive,    bonus,   vacation,    severance,    disability,
hospitalization, medical insurance, cafeteria, educational assistance or tuition
reimbursement, dependent care, life insurance, fringe benefit, welfare and other
benefits or any similar type of benefit or compensation  covering any present or
former OH+R Company employee, director or consultant (an "Employee Plan") of the
OH+R Companies,  whether written or oral,  whether or not subject to ERISA,  and
whether or not  terminated.  OH+R has provided  Telor with  complete and correct
copies  of the  documents  comprising  each  Employee  Plan  (and  any  document
embodying any related funding arrangement,  such as trust agreements,  custodial
account  agreements  or insurance  policies and annuity  contracts),  and (where
applicable)  the summary plan  description for each Employee Plan. Each Employee
Plan which is subject to ERISA conforms to, and its operation and administration
are in all material respects in

                                    A - 22

<PAGE>

compliance  with,  all  applicable  requirements  of  ERISA  including,  without
limitation, all funding, reporting,  disclosure and fiduciary requirements. With
respect to each Employee  Plan for which an annual report is required,  OH+R has
provided  Telor with complete and correct copies of the three most recent annual
reports  (including  all  schedules) of such Employee  Plan; no OH+R Company has
been  notified  by any  governmental  agency that any annual  report  filed with
respect to any Employee  Plan is  incomplete  or  incorrect.  Each Employee Plan
which is maintained  outside of the United  States and is a tax-exempt  approved
plan  has  been  operated  in all  material  respects  in  conformance  with the
applicable  statutes or governmental  regulations  and rulings  relating to such
plans in the jurisdictions and, to the extent relevant, the United States. There
has been no prohibited transaction under Section 406 of ERISA or Section 4975 of
the Code with  respect to any  Employee  Plan,  and no event has occurred and no
condition  exists that could result in the  imposition of any tax, fine or other
liability  under Section 4971,  4972, 4977 or 4979 of the Code or Section 502(c)
of ERISA.  There are no actions,  suits or claims  pending  (other than  routine
claims for  benefits) or to OH+R's  knowledge,  threatened  against any Employee
Plan, the assets of any Employee Plan, or any  administrator or fiduciary of any
Employee Plan.

      (b) Pension Plans. Schedule 2.18(b) identifies each Employee Plan which is
an "employee  pension benefit plan" (as defined in Section 3(2) of ERISA) (each,
a "Pension  Plan").  OH+R has provided Telor with complete and correct copies of
the most  recent  actuarial  valuation  report for each  Pension  Plan that is a
"defined  benefit plan" (as defined in Section 3(35) of ERISA) (each, a "Defined
Benefit  Pension  Plan") and the most recent  annual and periodic  accounting of
related plan assets for each Pension Plan. OH+R represents and warrants that:

            (i) each  Pension  Plan  which is  intended  to be  qualified  under
      Section  401(a)  of the  Code is in form  and  operation  qualified  under
      Section  401(a) of the Code and its related  trust is exempt under Section
      501(a) of the Internal  Revenue Code;  OH+R has provided Telor with a copy
      of the most  recent  Internal  Revenue  Service  determination  letter  or
      opinion  letter for each such Pension Plan (or, in the case of any Pension
      Plan for which an application for a determination  letter has been made, a
      copy  of the  materials  submitted  to the  Internal  Revenue  Service  in
      connection with such application);

            (ii) no  Defined  Benefit  Pension  Plan  has  been  terminated,  no
      liability to the Pension Benefit Guaranty Corporation ("PBGC") has been or
      is expected to be incurred  with  respect to any Defined  Benefit  Pension
      Plan and all  premiums  payable to the PBGC with  respect  to any  Defined
      Benefit Pension Plan have been properly paid;

            (iii)  there has been no  reportable  event  within  the  meaning of
      Section 4043 of ERISA with respect to any Defined Benefit Pension Plan;

            (iv) full and timely  payment has been made of all amounts  required
      to  have  been  paid  as  contributions  to  each  Pension  Plan,  and  no
      accumulated  funding  deficiency  as defined  in Section  302 of ERISA and
      Section 412 of the Internal  Revenue Code,  whether or not waived,  exists
      with respect to any Pension Plan;

                                    A - 23

<PAGE>

            (v) each OH+R Company has performed all  obligations  required to be
      performed by it under, and is not in default under, any Pension Plan, and,
      to  OH+R's  knowledge,  no other  party  is in  default  thereunder  or in
      violation thereof; and

            (vi) the present value of all "projected  benefit  obligations"  (as
      that term is defined in Statement of Financial  Accounting  Standards  No.
      87, Employers' Accounting for Pensions (FASB-87),  under each Pension Plan
      subject to Title IV of ERISA did not exceed, as of the most recent Pension
      Plan  valuation  date, the then current fair market value of the assets of
      such Pension Plan.

      (c) Welfare Plans.  Schedule 2.18(c)  identifies each Employee Plan of the
OH+R Companies which is an employee  welfare benefit plan (as defined in Section
3(1) of ERISA)  ("Welfare  Plan") and  identifies  which,  if any, of such plans
involve  benefits to retired  employees.  OH+R has provided  Telor with complete
copies of the most recent  actuarial  reports  for each  Welfare  Plan  covering
retired employees or their spouses and dependents.  Each Welfare Plan subject to
the requirements of the Consolidated  Omnibus Budget  Reconciliation Act of 1985
("COBRA") has complied with all  requirements  for  continuation  coverage under
group health  benefit plans under COBRA and there are no claims against any OH+R
Company for a failure or alleged  failure to comply with the COBRA  continuation
requirements.

      (d)   Multiemployer Plans.

            (i) Except as  described  in Schedule  2.18(d),  no OH+R Company has
      contributed  to a  "multiemployer  plan" (as  defined in Section  3(37) of
      ERISA) or "multiple employer plan." With respect to any multiemployer plan
      listed on Schedule  2.18(d),  each OH+R Company has made all contributions
      required  of it, and there is no claim  pending and no basis for any claim
      against  any  OH+R  Company  under  Section  515 of ERISA  for  delinquent
      contributions;

            (ii) no OH+R Company has made a "complete withdrawal" (as defined in
      Section  4203 of ERISA) or a "partial  withdrawal"  (as defined in Section
      4205 of ERISA) from any multiemployer  plan described in Schedule 2.18(d),
      and there  are no claims or  potential  claims  for  withdrawal  liability
      against  any OH+R  Company;  Schedule  2.18(d)  specifies  the  amount  of
      withdrawal  liability  that  would be  imposed  under  ERISA by each  such
      multiemployer  plan if,  immediately  after  the  Closing,  the  Surviving
      Corporation made a complete withdrawal from such plan;

            (iii)  there has been no sale of assets  of any OH+R  Company  which
      complied  with or was intended to comply with  Section 4204 of ERISA,  and
      there are no contingent or secondary  liabilities of any OH+R Company from
      such a sale of assets; and

            (iv) all  documents or  instruments,  as amended,  which specify the
      contributions  to be made by any OH+R  Company to any Pension  Plans which
      are  "multiple  employer  plans" or  "multiemployer  plan"  are  listed on
      Schedule   2.18(d)  hereto  or,  if   applicable,   the  current  rate  of
      contribution is set forth on Schedule 2.18(d).

                                    A - 24

<PAGE>

      (e)  Other  than  other  OH+R  Companies,  no  entity  is  required  to be
aggregated  with any OH+R Company under Section  414(b),  (c), (m) or (o) of the
Code.

      SECTION  2.19  Tangible  Properties.  Schedule  2.19  contains  a true and
complete list of all tangible  personal property owned by or leased to each OH+R
Company (the "Tangible  Personal  Property").  Except as shown on Schedule 2.19,
each OH+R Company has good and marketable  title free and clear of all Claims to
the Tangible  Personal  Property listed as owned by it. With respect to Tangible
Personal Property leased by an OH+R Company as lessee,  all leases,  conditional
sale contracts,  franchises or licenses  pursuant to which such OH+R Company may
hold or use (or permit  others to hold or use) such Tangible  Personal  Property
are  valid  and in full  force  and  effect,  and there is not under any of such
instruments any existing  default or event of default or event which with notice
or lapse of time or both would  constitute  such a default.  Each OH+R Company's
possession  and use of such  property has not been  disturbed,  and no Claim has
been asserted  against any OH+R Company  adverse to its rights in such leasehold
interests.  All  Tangible  Personal  Property  is  adequate  and  usable for the
purposes for which it is currently  used and has been  properly  maintained  and
repaired, and each item of Tangible Personal Property,  whether owned or leased,
is in good  operating  condition  and repair and has been  properly  maintained.
During  the past  three (3) years,  there has not been any  interruption  of the
operations  of any OH+R  Company's  business due to the  condition of any of the
Tangible Personal Property.

      SECTION  2.20  Real  Property.  No OH+R  Company  owns any real  property.
Schedule 2.20 sets forth a true and complete list and description of each parcel
of real property leased by each OH+R Company (the "Leased Parcels").  Each lease
covering a Leased Parcel is in full force and effect (there  existing no default
under  any such  lease or event  which,  with  the  lapse of time or  notice  or
otherwise,  would  constitute  a default),  conveys a leasehold  interest in the
leased  real estate  purported  to be  conveyed  thereunder,  and is and will be
following the Effective Time  enforceable by the applicable  OH+R Company or the
Surviving  Corporation in accordance  with its terms.  Each OH+R Company has the
right to use the Leased  Parcels  leased to it in  accordance  with the terms of
such leases free and clear of all Claims or other  interests  or rights of third
parties  (other than the lessor),  except those which do not or would not have a
material adverse effect on the Leased Parcels as used by such OH+R Company.  The
possession of such property by such OH+R Company has not been  disturbed and, to
OH+R's  knowledge,  no claim has been asserted against such OH+R Company adverse
to its rights in such leasehold interests. Each structure located on each Leased
Parcel is structurally  sound,  adequately  maintained and in good condition and
repair  consistent  with the uses to which it is presently being put or intended
to be put. All structures,  improvements  and fixtures on the Leased Parcels and
the  current  uses of the  Leased  Parcels  conform  to any  and all  applicable
federal, state and local laws, building, health and safety and other ordinances,
laws,  rules and  regulations.  No notice  from any  governmental  body or other
person has been served  upon,  or received  by, any OH+R  Company  claiming  any
violation of any such  ordinance,  law,  rule or  regulation,  or requiring  any
substantial   work,   repairs,   reclamation,   construction,   alterations   or
installation  on or in  connection  with any  Leased  Parcel  or any  structure,
improvement  or fixture  thereon  which has not been  complied  with or that any
right of access or other right enjoyed by any OH+R Company is being  modified or
terminated. There is no violation of any covenant,

                                    A - 25

<PAGE>

restriction or other agreement or understanding,  oral or written,  affecting or
relating  to  title  or  use of any  Leased  Parcel.  There  are no  pending  or
threatened  condemnation or similar proceedings or assessments  affecting any of
the  Leased  Parcels,  nor to  OH+R's  knowledge  is any  such  condemnation  or
assessment contemplated by any governmental authority.

      SECTION 2.21 Environmental Matters.

      (a) Compliance.  Each OH+R Company and all premises occupied, operated and
used by it (the "OH+R  Premises") are in compliance  with all  applicable  laws,
rules,   regulations,   orders,   ordinances,   judgments  and  decrees  of  all
governmental  authorities  (federal,  state,  and  local).  No OH+R  Company has
received  notice of, and OH+R has no knowledge  of, any past,  present or future
events, conditions, circumstances,  activities, practices, incidents, actions or
plans  of  any  OH+R  Company  or  any  OH+R  Company's   predecessors,   either
collectively,  individually  or severally,  which may interfere  with or prevent
continued  compliance,  or  which  may  give  rise to any  common  law or  legal
liability,  or otherwise form the basis of any claim, action, suit,  proceeding,
hearing,  or  investigation,  based  on or  related  to the  disposal,  storage,
handling, manufacture,  processing,  distribution, use, treatment, or transport,
or the emission,  discharge, release or threatened release into the environment,
of any  Substance  (as defined  below).  No part of any of the OH+R Premises has
been listed or proposed for listing on the National  Priorities List established
by the United  States  Environmental  Protection  Agency,  the List of Confirmed
Disposal Sites and Locations To Be Investigated  established by the Commonwealth
of  Massachusetts'  Department of  Environmental  Protection,  or any other such
list.

      (b)  Environmental  Substance  Liability.  No operating  practice is being
employed by any OH+R Company, and to OH+R's knowledge,  no event has occurred or
condition  exists,  that  could give rise to  liability  on the part of any OH+R
Company,  either  at  the  present  time  or in  the  future,  for  any  losses,
liabilities,   damages  (whether   consequential  or  otherwise),   settlements,
penalties,  interest,  expenses or costs of response actions (including any such
liability  on account  of the right of any  governmental  or  private  entity or
person,  and  including  closure  expenses,  costs of  assessment,  containment,
removal or other  response  actions  (other than  monitoring  transportation  or
disposal of materials  required to be transported or disposed of in the ordinary
course of business  consistent  with past  practice)  arising  under any rule or
federal,  state, or local statute,  or any regulation that has been  promulgated
pursuant  thereto,  or common  law,  as a result of or in  connection  with,  or
alleged to be as a result of or in connection with, the following:

            (i) the handling,  storage,  use,  transportation or disposal of any
      Substances in or near or from the OH+R Premises;

            (ii) the handling,  storage, use,  transportation or disposal of any
      Substances by any OH+R Company or its predecessors,  which Substances were
      a product,  by-product or otherwise resulted from the operations conducted
      by or on behalf of such OH+R Company or its predecessors;

                                    A - 26

<PAGE>

            (iii)  any  intentional  or  unintentional  emission,  discharge  or
      release of any  Substances  in or near or from the OH+R  Premises  into or
      upon  the  air,  surface  water,  ground  water  or land or any  disposal,
      handling,  manufacturing,  processing,  distribution,  use, treatment,  or
      transport of such Substances in or near or from the OH+R Premises by or on
      behalf of any OH+R Company or its predecessors; or

            (iv) the  presence  of any  toxic or  hazardous  building  materials
      (including but not limited to asbestos or similar  substances) in any OH+R
      Premises,  including but not limited to the inclusion of such materials in
      the exterior and interior walls, floors, ceilings, tile, insulation or any
      other portion of building structures.

      (c)  Environmental  Permits.  Each OH+R Company has obtained and holds all
registrations,  permits,  licenses,  and approvals issued by or on behalf of any
federal,  state or local  government body or agency  ("Environmental  Permits"),
that are required of any OH+R Company in  connection  with the  construction  or
operation of the OH+R  Premises,  discharge or emission of  Substances  from the
OH+R Premises or the generation, treatment, storage, transportation, or disposal
of any such  Substances.  Such  Environmental  Permits,  which are  described in
Schedule 2.21,  are currently  effective and sufficient for the operation of the
OH+R Premises as currently  conducted  and intended to be  conducted.  Each OH+R
Company is in full  compliance  with all terms and  conditions  of the  required
permits,  licenses and  authorizations,  and is also in full compliance with all
other   limitations,    restrictions,   conditions,   standards,   prohibitions,
requirements,  obligations, schedules, and timetables contained in those laws or
provisions or contained in any regulation,  code, plan, order, decree, judgment,
notice or demand letter issued, entered,  promulgated or approved thereunder and
applicable to any OH+R Company.

      As used in this Agreement, the term "Substances" shall mean any pollutant,
hazardous  substance,  hazardous  material,  hazardous  waste or toxic waste, as
defined  in any  presently  enacted  federal,  state  or  local  statute  or any
regulation  that has  been  promulgated  pursuant  thereto,  including,  without
limitation, medical waste and infectious waste.

      SECTION  2.22  Insurance.  Each OH+R  Company  is, and will be through the
Effective Time,  adequately insured with responsible  insurers in respect of its
properties,  assets and  businesses  against risks normally  insured  against by
companies in similar  lines of business  under similar  circumstances.  Schedule
2.22 correctly describes (by type, carrier,  policy number, limits, premium, and
expiration  date) the insurance  coverage  carried by the OH+R Companies,  which
insurance  will  remain in full  force and  effect  with  respect  to all events
occurring  prior to the  Effective  Time. No OH+R Company has failed to give any
notice or present  any claim  under any such  policy or binder in due and timely
fashion,  has received  notice of cancellation or non-renewal of any such policy
or binder, is aware of any threatened or proposed cancellation or non-renewal of
any such policy or binder,  has received notice of any insurance  premiums which
will be materially increased in the future or is aware of any insurance premiums
which will be  materially  increased  in the  future.  There are no  outstanding
claims under any such policy which have gone unpaid for more than 45 days, or as
to which the insurer has disclaimed liability.

      SECTION  2.23  Outstanding   Commitments.   Schedule  2.23  sets  forth  a
description of all existing contracts, agreements, understandings,  commitments,
licenses and franchises  (collectively  "Contracts"),  whether  written or oral,
relating to each OH+R Company and its properties and assets.  OH+R has delivered
or made  available  to Telor  true,  correct and  complete  copies of all of the
Contracts  specified on Schedule  2.23 which are in writing,  and Schedule  2.23
contains an accurate and complete  description of all Contracts which are not in
writing.  Each  OH+R  Company  has paid in full all  amounts  due as of the date
hereof under each of the  Contracts  identified  in Schedule  2.23 and as of the
Effective  Time  will  have  satisfied  in  full  all  of  its  liabilities  and
obligations  thereunder due in the ordinary  course of business  consistent with
past practice  prior to the Effective  Time.  All of the Contracts  described in
Schedule  2.23 are in full force and effect.  Each OH+R  Company  and, to OH+R's
knowledge,  each other party thereto have performed all the obligations required
to be performed by them to date,  have received no notice of default and are not
in default  (with due notice or lapse of time or both) under any  Contracts.  No
OH+R Company has a present  expectation or intention of not fully performing all
its obligations  under each of the Contracts to which it is a party, and no OH+R
Company has knowledge of any breach or anticipated  breach by the other party to
any contract or commitment to which any OH+R Company is a party. There exists no
actual or, to the knowledge of OH+R,  threatened  termination,  cancellation  or
limitation  of the business  relationship  of any OH+R Company with any party to
any of the Contracts.

      SECTION 2.24 Intellectual  Property.  Set forth in Schedule 2.24 is a list
and brief  description  of all  patents,  patent  rights,  patent  applications,
trademarks,  trademark  applications,  service marks, service mark applications,
trade names and registered  copyrights,  and all applications for such which are
in the process of being  prepared,  owned by or  registered  in the name of each
OH+R Company, or of which any OH+R Company is a licensor or licensee or in which
any OH+R  Company  has any right,  and in each case a brief  description  of the
nature of such right.  Each OH+R Company owns or possesses  adequate licenses or
other  rights to use all patents,  patent  applications,  trademarks,  trademark
applications, service marks, service mark applications, trade names, copyrights,
manufacturing  processes,  formulae,  trade secrets and know-how  (collectively,
"Intellectual  Property")  necessary or desirable to the conduct of its business
as currently conducted and as proposed to be conducted,  and no claim is pending
or  threatened to the effect that the  operations  of any OH+R Company  infringe
upon or  conflict  with the  asserted  rights  of any  other  person  under  any
Intellectual Property,  and to OH+R's knowledge,  there is no basis for any such
claim (whether or not pending or threatened).  No Claim is pending or threatened
to the effect that any such Intellectual  Property owned or licensed by any OH+R
Company or which any OH+R Company  otherwise has the right to use, is invalid or
unenforceable  by such OH+R Company and to OH+R's  knowledge,  there is no basis
for any such  Claim  (whether  or not  pending  or  threatened).  All  technical
information  developed by and  belonging to any OH+R Company  which has not been
patented has been kept confidential.  No OH+R Company has granted or assigned to
any other person or entity any right to manufacture, have manufactured, assemble
or sell its products or proposed products or to provide its services or proposed
services.  Most employees of the OH+R Companies,  including  senior  management,

      (c) all  proxies,  powers of  attorney,  agency  agreements  or other like

business or affairs of each OH+R Company.

      SECTION  2.28  Assumptions,  Guaranties,  Etc.  of  Indebtedness  of Other
Persons. No OH+R Company has assumed,  guaranteed,  endorsed or otherwise become
directly  or  contingently  liable  on  any  indebtedness  of any  other  person
(including,  without  limitation,  liability by way of agreement,  contingent or
otherwise,  to purchase,  to provide  funds for  payment,  to supply funds to or
otherwise  invest in the debtor,  or otherwise  to assure the  creditor  against
loss),  except for  guaranties  by  endorsement  of negotiable  instruments  for
deposit or collection in the ordinary course of business.

      SECTION 2.29 Transactions with Affiliates. Except as set forth on Schedule

partner or holder of any equity interest, is a party to any transaction

                                    A - 29

<PAGE>

with any OH+R Company,  including any contract,  agreement or other  arrangement
providing  for  the  employment  (except  for  contracts,  agreements  or  other
arrangements which are terminable on notice by such OH+R Company without cost or
other  liability to such OH+R Company) of,  furnishing of services by, rental of
real or personal  property  from or  otherwise  requiring  payments or involving
other obligations to any such person or firm.

      SECTION 2.30 Records.  The minute books, stock certificate books and stock
transfer  ledgers of each OH+R  Company are complete and correct in all material
respects with respect to the matters set forth therein and have been  maintained
in a manner consistent with good business practice.

      SECTION 2.31 Projections; Working Capital. The projected income statements
and balance  sheets of the OH+R  Companies for the fiscal years ending and as of
December 31, 1996,  1997,  1998 and 1999 provided by OH+R to Telor were prepared
in good faith and on a reasonable basis, based on the knowledge, information and
belief of OH+R's management.  The projections are based upon various assumptions
relating to general economic  conditions,  market  conditions in the industry in
which the OH+R Companies  compete,  operating  performance of the OH+R Companies
(based  on  historic  levels  of  operating   expenses)  and  other  assumptions
concerning future events and circumstances which, although considered reasonable
by OH+R, are inherently subject to significant  uncertainties and contingencies,
many of which are beyond OH+R's control. Accordingly, the projections may not be
realized. Actual results may vary materially and adversely from those shown. The
projections were not prepared in compliance with the published guidelines of the
SEC  or  the  American  Institute  of  Certified  Public  Accountants  regarding
forecasts or projections,  or in compliance with generally  accepted  accounting
principles.  Ernst & Young,  LLP,  independent  accountants  for OH+R,  have not
audited  or  otherwise  verified  the  projections  and,  accordingly,  have not
expressed an opinion or any other form of assurance with respect thereto.  Since
the date  when the  projections  were  made,  there  have  been no  occurrences,
developments  or  facts  which  would  cause  OH+R to  believe  either  that the
projections  are not reasonable or that the  assumptions on which they are based
are incorrect.  Based on current  circumstances and reasonably  projected needs,
each OH+R Company has and will have  sufficient  available  working capital with
which to  operate  its  business  as  currently  conducted  and  intended  to be
conducted  through at least March 31,  1996,  provided  that OH+R may obtain the
financing described in Section 4.07(f).

      SECTION  2.32  Information  Supplied  for  Proxy  Statement.  None  of the
information  supplied  or to be  supplied  by OH+R  or its  agents,  counsel  or
accountants for inclusion in the Proxy Statement, from the date such information
is supplied to the time of the Telor  Stockholders  Meeting  held in  accordance
with  Section 1.09  hereof,  contains or will contain any untrue  statement of a
material  fact or omits or will omit to state any material  fact  required to be
stated in the  Proxy  Statement  or  necessary  in order to make the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.

      SECTION 2.33 Tax-Free Reorganization.

      (a) The Share  Conversion  Fraction for the exchange of shares of stock of
OH+R  for  Telor  Stock  in the  Merger  was  negotiated  through  arm's  length
bargaining.

      (b) OH+R has no plan or intention to reacquire  any of the shares of Telor
Stock to be issued in the Merger.

      (c) OH+R has no plan or intention  to sell or otherwise  dispose of any of
the assets of OH+R acquired in the Merger,  except for dispositions  made in the
ordinary  course of business or transfers  described in Section  368(a)(2)(C) of
the Code.

      (d) The  liabilities of OH+R assumed by the Surviving  Corporation and the
liabilities as to which the transferred assets of OH+R are subject were incurred
by OH+R in the ordinary course of its business.

      (e) Following the Effective Time, the Surviving  Corporation will continue
the historic  business of OH+R or use a significant  portion of OH+R's  historic
business assets in a business.

      (f) OH+R and the OH+R  Securityholders  will pay their respective expenses
incurred in connection with the Merger.

      (g) (i) None of the compensation to be received by any OH+R Securityholder
who is also an employee of OH+R will be separate consideration for, or allocable
to, any of their shares of OH+R capital stock,  (ii) none of the shares of Telor
Stock to be received by any OH+R  Securityholder who is also an employee of OH+R
will be separate  consideration  for, or allocable to, any employment  agreement
and  (iii)  the  compensation  paid to any  OH+R  Securityholder  who is also an
employee of OH+R will be for services actually rendered and will be commensurate
with  amounts  paid to third  parties  bargaining  at arms'  length for  similar
services.

      SECTION 2.34  Disclosure.  All documents and schedules  delivered or to be
delivered by or on behalf of the OH+R Companies to Telor in connection with this
Agreement  and the  transactions  contemplated  hereby  are  true,  correct  and
complete. Neither this Agreement, nor any Schedule or Exhibit to this Agreement,
contains  any  untrue  statement  of a material  fact or omits a  material  fact
necessary to make the statements  contained  herein or therein,  in light of the
circumstances in which made, not misleading.

      SECTION  2.35  Adoption of  Strategic  Plan.  The OH+R Board of  Directors
unanimously  adopted the OH+R  Strategic  Plan in the form  presented by John C.
Garbarino  to the Board of  Directors  of Telor on January  12,  1996,  and such
adoption has not been revoked.

All of  such  shares  are  duly  authorized,  validly  issued,  fully  paid  and

local  rules,  laws and  regulations.  The  designations,  powers,  preferences,
rights,  qualifications,  limitations and  restrictions in respect of each class

Section  5.07(a)),  no shares  held in the  corporate  treasury  of Telor and no
shares  reserved  for  issuance,  except as set forth on Schedule  3.01.  To the
knowledge of Telor, based solely on filings made with the SEC and a stockholders

rights (phantom or otherwise),  joint venture,  partnership or other commitments
of any nature  relating to shares of the capital stock of Telor.  As of the date

securities  or any  interest  therein or to pay any  dividend  or make any other
distribution in respect  thereof.  Except as set forth on Schedule 3.01, none of
Telor's outstanding Equity Securities or authorized capital stock are subject to
any  rights  of  redemption,  repurchase,  rights of first  refusal,  preemptive
rights,  registration  rights  or other  similar  rights,  whether  contractual,
statutory  or  otherwise,  for the benefit of Telor,  any holder of Telor Equity
Securities or any other Person.  Except as set forth on Schedule 3.01, there are
no  restrictions  on the transfer of shares of capital stock of Telor other than
those  imposed by relevant  federal and state  securities  laws and as otherwise
contemplated by this Agreement.

incorporation  and is duly  licensed  or  qualified  to  transact  business as a
foreign  corporation  and is in good  standing  in each  jurisdiction  listed on
Schedule 3.02,  such  jurisdictions  being the only  jurisdictions  in which the
nature of Telor's business or the character of the properties owned or leased by
Telor  requires  such  licensing or  qualification.  Telor has no  Subsidiaries.
Except  as set  forth on  Schedule  3.02,  Telor  does not (a) own of  record or
beneficially,  directly  or  indirectly,  (i) any  shares  of  capital  stock or

and  authority  to own and hold its  properties  and to carry on its business as

performance  of this  Agreement  and the documents  contemplated  hereby and the
consummation of the Merger and the other  transactions  contemplated  hereby and

obligation of, Telor  enforceable  against Telor in accordance with their terms.

which  agreement  shall  be  binding  unless  the  Board of  Directors  of Telor
determines not to proceed with the Merger and such  determination  has been made

termination  or  give  rise  to  any  right  of  termination,   cancellation  or
acceleration  of the maturity of any payment date of any of the  obligations  of

rule, regulation, judgment, decree, order, governmental permit, license or order
or any of the terms, conditions or provisions of any mortgage,  indenture, note,
license,  agreement or other instrument or obligation related to Telor or any of

the related statements of income

                                    A - 33

<PAGE>

and cash flow and notes  thereto for the fiscal  years ended  December 31, 1993,
December  31, 1994 and December 31, 1995.  All such  financial  statements  (the
"Telor  Financial  Statements")  have been prepared in accordance with generally
accepted accounting principles  consistently applied (with the exception,  as of
the date hereof,  of the lack of notes thereto for the  Financial  Statements at
and as of December  31,  1995) and were  prepared  from the books and records of
Telor, which books and records are complete and correct in all material respects
and accurately reflect all transactions of Telor's business. The Telor Financial
Statements  fairly  present  the  financial  position  of Telor as of the  dates
thereof,  and the results of its operations and cash flows for the periods ended
on  the  dates  thereof.   The  Telor  Financial   Statements  reflect  reserves
appropriate  and  adequate for all known  material  liabilities  and  reasonably
anticipated  losses as required by  generally  accepted  accounting  principles.
Telor has disclosed to OH+R all material  facts  relating to the  preparation of
the Telor Financial Statements, including the basis of accounting for affiliated
transactions, and Telor has delivered to OH+R complete and correct copies of all
letters of representation  from Telor delivered to its accountants in connection
with the  preparation  of the Telor  Financial  Statements,  and all  management
letters from the accountants to Telor.

due or to become due,  accrued,  absolute,  contingent  or otherwise  except for
liabilities and  obligations  incurred since the date of the Telor Balance Sheet
in the ordinary course of business and consistent with past practice. Telor does
not know of, and has no reason to know of, any basis for the  assertion  against
it of any liability or obligation not fully reflected or reserved against in the
Telor  Balance  Sheet  or  incurred  in the  ordinary  course  of  business  and
consistent  with past practice  since the date  thereof.  Except as set forth on
Schedule 3.06, Telor is not bound by any agreement, or subject to any charter or
other  corporate  restriction  or any legal  requirement,  which has,  or in the
future can  reasonably  be expected to have,  a material  adverse  effect on its
business.

      SECTION 3.07 Absence of Adverse Change; Conduct of Business. Except as set
forth on Schedule  3.07,  since the date of the Telor Balance  Sheet,  Telor has
conducted its business only in the ordinary  course of business  consistent with
recent past practice (it being understood that Telor is not currently conducting
any significant research and development activities), there has been no material
adverse  change in the  business  of Telor and  there is no known  condition  or
development or  contingency of any kind existing or which,  so far as reasonably
can be foreseen by Telor,  may result in any such change.  Without  limiting the
foregoing,  except as set forth on Schedule 3.07, disclosed by Telor in a filing
with the SEC identified on Schedule 3.07 or permitted  pursuant to Section 5.07,
since September 30, 1995, there has not been, occurred or arisen:

required  forms,  reports and documents  with the SEC required to be filed by it
pursuant  to the  federal  securities  laws and the SEC  rules  and  regulations
thereunder,  all of which have complied as of their  respective  filing dates in
all material respects with all applicable requirements of the Securities Act and
the Exchange Act, and the rules and regulations promulgated thereunder.  None of
such  forms,  reports  or  documents  at the time  filed,  contained  any untrue
statement of a material  fact or omitted to state any material  fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading.

on a timely  basis all Tax Returns  and tax  reports  required to be filed on or
before  the  date  hereof  with the  appropriate  governmental  agencies  in all
jurisdictions  in which such returns and reports are  required to be filed,  and
all such Tax Returns were correct and complete in all material respects.  Except
as set forth on  Schedule  3.09,  all Taxes  which have become due or payable or
required to be collected by Telor or as  otherwise  attributable  to any periods

      such application);

            (ii) no  Defined  Benefit  Pension  Plan  has  been  terminated,  no

      to any Defined Benefit  Pension Plan and all premiums  payable to the PBGC
      with respect to any Defined Benefit Pension Plan have been properly paid;

            (iii)  there has been no  reportable  event  within  the  meaning of
      Section 4043 of ERISA with respect to any Defined Benefit Pension Plan;

            (iv) full and timely  payment has been made of all amounts  required
      to  have  been  paid  as  contributions  to  each  Pension  Plan,  and  no

      with respect to any Pension Plan;

            (v) Telor has performed all obligations  required to be performed by
      it under,  and is not in default  under,  any Pension  Plan,  and no other
      party is in default thereunder or in violation thereof; and

under  COBRA  and there are no claims  against  Telor for a failure  or  alleged
failure to comply with the COBRA continuation requirements.

      (d)   Multiemployer Plans.

      to a  "multiemployer  plan"  (as  defined  in  Section  3(37) of ERISA) or
      "multiple employer plan." With respect to any multiemployer plan listed on
      Schedule 3.15, Telor has made all contributions  required of it, and there
      is no claim  pending and no basis for any claim  against under Section 515
      of ERISA for delinquent contributions;

            (ii)  Telor has not made a  "complete  withdrawal"  (as  defined  in

      4205 of ERISA) from any multiemployer  plan described in Schedule 3.15 and
      there are no claims or potential claims for withdrawal  liability  against
      Telor;  Schedule 3.15  specifies the amount of withdrawal  liability  that
      would  be  imposed  under  ERISA  by  each  such  multiemployer  plan  if,
      immediately after the Closing,  the Surviving  Corporation made a complete
      withdrawal from such plan;

            (iii) there has been no sale of assets of Telor which  complied with

      and

            (iv) all  documents or  instruments,  as amended,  which specify the
      contributions to be made by Telor to any Pension Plans which are "multiple
      employer plans" or "multiemployer plan" are listed on Schedule 3.15 hereto
      or,  if  applicable,  the  current  rate of  contribution  is set forth on
      Schedule 3.15.

      (e) No entity is  required  to be  aggregated  with  Telor  under  Section
414(b), (c), (m) or (o) of the Code.

      SECTION  3.16  Tangible  Properties.  Schedule  3.16  contains  a true and
complete list of all tangible personal property owned by or leased to Telor (the
"Telor Tangible Personal Property"). Except as shown on Schedule 3.16, Telor has
good and  marketable  title free and clear of all  Claims to the Telor  Tangible
Personal  Property.  With respect to Telor Tangible  Personal Property leased by
Telor as lessee, all leases, conditional sale contracts, franchises or

                                    A - 41

<PAGE>

licenses  pursuant to which  Telor may hold or use (or permit  others to hold or
use) Telor  Tangible  Personal  Property are valid and in full force and effect,
and there is not under any of such  instruments any existing default or event of
default  or event  which with  notice or lapse of time or both would  constitute
such a  default.  Telor's  possession  and use of  such  property  has not  been
disturbed, and no Claim has been asserted against Telor adverse to its rights in
such leasehold  interests.  All Telor Tangible Personal Property is adequate and
usable for the  purposes for which it is  currently  used and has been  properly
maintained  and repaired,  and each item of Telor  Tangible  Personal  Property,
whether owned or leased, is in good operating  condition and repair and has been
properly  maintained.  During the past  three (3) years,  there has not been any
interruption  of the operations of Telor's  business due to the condition of any
of the Telor Tangible Personal Property.

      SECTION 3.17 Real Property. Telor does not own any real property. Schedule
3.17 sets forth a true and complete list and  description of each parcel of real
property  leased by Telor (the "Telor Leased  Parcels").  Each lease  covering a
Telor Leased Parcel is in full force and effect (there existing no default under
any such lease or event  which,  with the lapse of time or notice or  otherwise,
would  constitute  a default),  conveys a leasehold  interest in the leased real
estate  purported to be conveyed  thereunder,  and is and will be following  the
Effective Time  enforceable by the Surviving  Corporation in accordance with its
terms.  Telor  has the  right to use the Telor  Leased  Parcels  leased to it in
accordance  with the terms of such  leases free and clear of all Claims or other
interests  or rights of third  parties  (other than the  lessor),  except as set
forth on  Schedule  3.17 and  those  which do not or would  not have a  material
adverse effect on the Telor Leased  Parcels as used by Telor.  The possession of
such  property  by Telor  has not been  disturbed  and,  except  as set forth on
Schedule 3.17, to Telor's  knowledge,  no claim has been asserted  against Telor
adverse to its rights in such leasehold  interests.  Each  structure  located on
each Telor Leased Parcel is  structurally  sound,  adequately  maintained and in
good  condition  and repair  consistent  with the uses to which it is  presently
being put or intended to be put. All  structures,  improvements  and fixtures on
the Telor  Leased  Parcels  and the  current  uses of the Telor  Leased  Parcels
conform  to any and all  applicable  federal,  state and local  laws,  building,
health and safety and other ordinances,  laws, rules and regulations.  No notice
from any governmental body or other person has been served upon, or received by,
Telor claiming any violation of any such ordinance,  law, rule or regulation, or
requiring any substantial work, repairs, reclamation,  construction, alterations
or  installation  on or in connection with Telor Leased Parcel or any structure,
improvement  or fixture  thereon  which has not been  complied  with or that any
right of access or other right enjoyed by Telor is being modified or terminated.
There  is no  violation  of any  covenant,  restriction  or other  agreement  or
understanding,  oral or written,  affecting or relating to title or use of Telor
Leased  Parcel.  There are no  pending  or  threatened  condemnation  or similar
proceedings or  assessments  affecting any of the Telor Leased  Parcels,  nor to
Telor's  knowledge is any such  condemnation  or assessment  contemplated by any
governmental authority.

      SECTION 3.18 Environmental Matters.

      (a) Compliance.  Telor and all premises occupied,  operated and used by it
(the "Telor  Premises")  are in  compliance  with all  applicable  laws,  rules,
regulations, orders, ordinances,

                                    A - 42

past,  present  or  future  events,   conditions,   circumstances,   activities,
practices,  incidents, actions or plans of Telor or any of Telor's predecessors,
either  collectively,  individually  or severally,  which may interfere  with or
prevent continued compliance,  or which may give rise to any common law or legal
liability,  or otherwise form the basis of any claim, action, suit,  proceeding,
hearing,  or  investigation,  based  on or  related  to the  disposal,  storage,
handling, manufacture,  processing,  distribution, use, treatment, or transport,
or the emission,  discharge, release or threatened release into the environment,

      (b)  Environmental  Substance  Liability.  No operating  practice is being

exists,  that could give rise to liability  on the part of Telor,  either at the
present time or in the future,  for any losses,  liabilities,  damages  (whether
consequential or otherwise), settlements, penalties, interest, expenses or costs
of response actions (including any such liability on account of the right of any
governmental or private entity or person, and including closure expenses,  costs
of  assessment,  containment,  removal or other  response  actions  (other  than
monitoring transportation or disposal of materials required to be transported or
disposed of in the ordinary  course of business  consistent  with past practice)
arising under any rule or federal,  state,  or local statute,  or any regulation
that has been promulgated  pursuant thereto, or common law, as a result of or in
connection  with,  or alleged to be as a result of or in  connection  with,  the
following:

      Substances by Telor or its predecessors,  which Substances were a product,
      by-product or otherwise  resulted from the  operations  conducted by or on

            (iii)  any  intentional  or  unintentional  emission,  discharge  or

      transport of such  Substances in or near or from the Telor  Premises by or
      on behalf of Telor or its predecessors; or

            (iv) the  presence  of any  toxic or  hazardous  building  materials
      (including but not limited to asbestos or similar substances) in any Telor
      Premises,  including but not limited to the inclusion of such materials in
      the exterior and interior walls, floors, ceilings, tile, insulation or any

      (c) Environmental  Permits. Telor has obtained and holds all Environmental
Permits  that are  required  of Telor in  connection  with the  construction  or
operation of the Telor  Premises,  discharge or emission of Substances  from the
Telor  Premises  or  the  generation,  treatment,  storage,  transportation,  or
disposal of any such Substances. Such Environmental Permits, which are described
in Schedule  3.18,  are currently  effective and sufficient for the operation of
the Telor Premises as currently conducted and intended to be conducted. Telor is
in full  compliance  with all  terms and  conditions  of the  required  permits,
licenses  and  authorizations,  and is also in full  compliance  with all  other
limitations,  restrictions,  conditions, standards, prohibitions,  requirements,
obligations,  schedules, and timetables contained in those laws or provisions or
contained in any regulation,  code, plan,  order,  decree,  judgment,  notice or
demand letter issued, entered, promulgated or approved thereunder and applicable
to Telor.

      SECTION 3.19 Insurance.  Telor is, and will be through the Effective Time,
adequately  insured  with  responsible  insurers  in respect of its  properties,
assets and  business  against  risks  normally  insured  against by companies in
similar lines of business under similar  circumstances.  Schedule 3.19 correctly
describes (by type,  carrier,  policy number,  limits,  premium,  and expiration
date) the insurance  coverage  carried by Telor,  which insurance will remain in
full  force  and  effect  with  respect  to all  events  occurring  prior to the

of any threatened or proposed  cancellation or non-renewal of any such policy or
binder,  has  not  received  notice  of any  insurance  premiums  which  will be
materially  increased in the future and is not aware of any  insurance  premiums

and brief  description  of all  patents,  patent  rights,  patent  applications,
trademarks,  trademark  applications,  service marks, service mark applications,
trade names and registered  copyrights,  and all applications for such which are
in the process of being  prepared,  owned by or registered in the name of Telor,
or of which Telor is a licensor or licensee or in which Telor has any right, and
in each case a brief  description  of the  nature of such  right.  Telor owns or
possesses  adequate  licenses or other rights to use all  Intellectual  Property
necessary or desirable to the conduct of its business as currently conducted and
as proposed to be conducted, and no claim is pending or threatened to the effect
that the operations of Telor infringe upon or conflict with the asserted  rights
of any other person under any Intellectual  Property,  and to Telor's knowledge,
there is no basis for any such claim (whether or not pending or threatened).  No
Claim is pending or threatened to the effect that any such Intellectual Property
owned or  licensed by Telor or which  Telor  otherwise  has the right to use, is
invalid or unenforceable by Telor, and to Telor's  knowledge,  there is no basis
for any such  Claim  (whether  or not  pending  or  threatened).  All  technical
information  developed by and belonging to Telor which has not been patented has
been kept confidential. Telor has not granted or assigned to any other person or
entity  any  right  to  manufacture,  have  manufactured,  assemble  or sell its
products or proposed  products or to provide its services or proposed  services.

delivered by or on behalf of Telor to OH+R in connection with this Agreement and

between the parties hereto with

<PAGE>

respect to the subject  matter hereof and  supersedes  all prior oral or written
agreements and  understandings  relating to the subject matter hereof including,
without  limitation,  that certain letter of intent between Telor and OH+R dated

this Agreement may be modified or amended only by written agreement  executed by
all parties hereto, except as otherwise provided in Section 1.16.

      SECTION 9.04 Waivers and  Consents.  No failure or delay by a party hereto
in exercising any right, power or remedy under this Agreement,  and no course of
dealing between the parties hereto, shall operate as a waiver of any such right,
power or remedy of the party. No single or partial exercise of any right,  power
or remedy  under  this  Agreement  by a party  hereto,  nor any  abandonment  or
discontinuance  of steps to  enforce  any such  right,  power or  remedy,  shall
preclude such party from any other or further  exercise  thereof or the exercise
of any other right,  power or remedy hereunder.  The election of any remedy by a
party hereto shall not  constitute a waiver of the right of such party to pursue
other  available  remedies.  No notice  to or  demand  on a party not  expressly
required under this Agreement  shall entitle the party  receiving such notice or
demand  to  any  other  or  further   notice  or  demand  in  similar  or  other
circumstances  or  constitute  a waiver of the rights of the party  giving  such
notice or demand to any other or  further  action in any  circumstances  without
such notice or demand. The terms and provisions of this Agreement may be waived,
or  consent  for the  departure  therefrom  granted,  only by  written  document
executed by the party entitled to the benefits of such terms or  provisions.  No
such  waiver or consent  shall be deemed to be or shall  constitute  a waiver or
consent with respect to any other terms or provisions of this Agreement, whether
or not  similar.  Each such  waiver or consent  shall be  effective  only in the
specific  instance  and for the  purpose  for which it was given,  and shall not
constitute a continuing waiver or consent.

      SECTION 9.05 Assignment.  Neither this Agreement, nor any right hereunder,
may be  assigned  by either of the  parties  hereto  without  the prior  written
consent of the other party.

      SECTION 9.06 Parties in Interest. This Agreement shall be binding upon and
inure  solely to the benefit of each party hereto and their  permitted  assigns,
and nothing in this  Agreement,  express or implied,  is intended to confer upon
any other  person any rights or  remedies of any nature  whatsoever  under or by
reason of this Agreement. Nothing in this Agreement shall be construed to create
any rights or obligations  except between the parties  hereto,  and no person or
entity shall be regarded as a third-party beneficiary of this Agreement.

      SECTION 9.07 Governing Law. This Agreement and the rights and  obligations
of the parties  hereunder  shall be construed in accordance with and governed by
the internal law of The Commonwealth of Massachusetts,  without giving effect to

      SECTION  9.08  Jurisdiction  and Service of Process.  Any legal  action or
proceeding  with respect to this  Agreement  may be brought in the courts of the
Commonwealth of Massachusetts or of the United States of America for the Eastern
District of Massachusetts.  By execution and delivery of this Agreement, each of
the parties hereto accepts for itself and in respect of its property,  generally
and  unconditionally,  the  jurisdiction  of the aforesaid  courts.  The parties
hereby irrevocably waive any objection or defense that they may now or hereafter
have to the  assertion  of personal  jurisdiction  by any such court in any such
action or to the laying of the venue of any such action in any such  court,  and
hereby waive,  to the extent not prohibited by law, and agree not to assert,  by
way of motion,  as a defense,  or otherwise,  in any such proceeding,  any claim
that it is not subject to the  jurisdiction of the  above-named  courts for such
proceedings.  Each of the parties hereto irrevocably  consents to the service of
process of any of the aforementioned  courts in any such action or proceeding by
the mailing of copies thereof by registered mail, postage prepaid,  to the party
at its  address  set forth in  Section  9.01  hereof and  irrevocably  waive any
objection or defense that it may now or hereafter have to the sufficiency of any
such service of process in any such  action.  Nothing in this Section 9.08 shall
affect the rights of the parties to commence  any such action in any other forum
or to serve process in any such action in any other manner permitted by law.

      SECTION  9.09  Severability.  In the  event  that any  court of  competent
jurisdiction shall finally determine that any provision, or any portion thereof,
contained in this Agreement shall be void or unenforceable in any respect,  then
such provision shall be deemed limited to the extent that such court  determines
it enforceable,  and as so limited shall remain in full force and effect. In the
event that such court shall  determine any such provision,  or portion  thereof,
wholly   unenforceable,   the  remaining  provisions  of  this  Agreement  shall
nevertheless remain in full force and effect.

contributed  to its revision;  and (ii) the rule of  construction  to the effect
that any  ambiguities  are  resolved  against  the  drafting  party shall not be
employed in the interpretation of this Agreement.

      SECTION  9.11  Headings  and  Captions.  The  headings and captions of the

interpreting  the  meaning  or  construction  of any of the terms or  provisions
hereof.

      SECTION 9.12  Enforcement.  Each of the parties  hereto  acknowledges  and
agrees  that the rights  acquired  by each party  hereunder  are unique and that
irreparable  damage would occur in the event that any of the  provisions of this
Agreement to be performed  by the other party were not  performed in  accordance
with their specific terms or were otherwise breached.  Accordingly,  in addition
to any other  remedy to which  the  parties  hereto  are  entitled  at law or in
equity,  each party hereto shall be entitled to an injunction or  injunctions to
prevent breaches

hereunder to submit to jurisdiction.

      SECTION 9.13 Reliance. The parties hereto agree that,  notwithstanding any

other party or pursuant to this Agreement.

billed  to or  incurred  by OH+R  in  connection  with  this  Agreement  and the
transactions contemplated hereby.

and warrants to the other that no broker,  finder or other financial  consultant
has acted on its behalf in connection  with this  Agreement or the  transactions
contemplated  hereby in such a way as to create any liability on the other. Each
of the parties  hereto agrees to indemnify and save the other  harmless from any
claim or demand for  commission  or other  compensation  by any broker,  finder,
financial  consultant or similar  agent  claiming to have been employed by or on
behalf  of such  party  and to bear  the  cost of  legal  expenses  incurred  in
defending against any such claim.

      SECTION 9.16 Confidentiality.  Each party acknowledges and agrees that any
information or data it has acquired from the other party, not otherwise properly

You have asked Adams,  Harkness & Hill, Inc.  ("AH&H") for its opinion as to the

results;  (2) OH&R's  business and outlook for the foreseeable  future;  (3) the
Agreement  and Plan of Merger  relating to the  Transaction;  and (4) such other
information  regarding  the  Company  and  OH&R as we  determine  necessary  and
appropriate to render the opinion referred to above.

foregoing  information provided to us and have relied, with your consent, on its
being  complete  and  accurate in all  material  respects.  With  respect to the
financial forecasts,  we have assumed that they have been reasonably prepared on
bases reflecting the best currently  available estimates and judgments of OH&R's
management  as to the  future  financial  performance  of OH&R.  Our  opinion is
rendered on the basis of securities market conditions  prevailing as of the date
hereof and on the  conditions and  prospects,  financial and  otherwise,  of the
Company and OH&R as known to us on the date hereof.
