         2.       REGISTRATION RIGHTS.

                  2.1  Registration on Demand.

                            2.1.1 Demand.  At any time following a Trigger Date,
upon the written  request  (the  "Demand")  of RHI that the  Company  effect the
registration  under  the  Securities  Act of all or  part of  RHI's  Registrable
Securities,  the  Company  shall:  use its best  efforts to  effect,  as soon as
practicable  and in any event  within 90 days after the Demand is received  from
RHI, the registration  under the Securities Act (but not including by means of a
shelf  registration  pursuant  to Rule 415 under  the  Securities  Act),  of the
Registrable  Securities  which the Company has been so  requested to register by
RHI.

                            2.1.2 Registration of Other Securities. Whenever the
Company shall effect a  registration  pursuant to this Section 2.1 in connection
with an  underwritten  offering  by RHI of  Registrable  Securities,  holders of
securities of the Company who have "piggyback"  registration  rights may include
all or a portion of such  securities  in such  registration,  offering  or sale;
provided that, if the amount of  Registrable  Securities to be sold by RHI is to
be reduced  because of the views of the managing  underwriter  or  underwriters,
then the securities  (other than the Registrable  Securities) to be sold by such
other holders  participating in such offering shall be reduced by allocating the
securities  to be sold by such  other  holders  in  proportion  to the number of
securities proposed to be sold in such offering by such holders.

                            2.1.3  Registration  Statement  Form.  Registrations
under this  Section 2.1 shall be on such  appropriate  registration  form of the
Commission as shall be selected by the Company. The Company shall include in any
such registration  statement all information which, in the opinion of counsel to
the Company, is required to be included.

                            2.1.4   Expenses.   The   Company   shall   pay  the
Registration Expenses in connection with any registration  requested pursuant to
this Section 2.1.

                            2.1.5   Effective    Registration    Statement.    A
registration  requested pursuant to this Section 2.1 shall not be deemed to have
been effected (i) unless a registration statement





                                       -5-


with  respect  thereto  has  become  effective,  (ii)  if  after  it has  become
effective, such registration is interfered with by any stop order, injunction or
other order or  requirement of the  Commission or other  governmental  agency or
court for any  reason  not  attributable  to RHI and has not  thereafter  become
effective,  or (iii) if the conditions to closing  specified in the underwriting
agreement,  if any,  entered into in connection with such  registration  are not
satisfied or waived, other than by reason of a failure on the part of RHI.

                            2.1.6 Selection of Underwriters.  In connection with
each underwritten  offering, RHI shall promptly select an underwriter subject to
the approval of the Company (which approval shall not be  unreasonably  withheld
by the Company).

                            2.1.7  Limitations on  Registration  on Demand.  The
Company  shall not be  required  to prepare  and file a  registration  statement
pursuant  to this  Section  2.1  which  would  become  effective  within 90 days
following  the  effective  date  of  a  registration  statement  (other  than  a
registration  statement  filed  on Form  S-8)  filed  by the  Company  with  the
Commission  pertaining to an underwritten  public  offering of convertible  debt
securities  or equity  securities  for cash for the  account  of the  Company or
another  holder of  securities  of the Company or if the Company  gives  written
notice to RHI  within  10 days of  receipt  of a Demand  that the  Company  will
initiate within 30 days the preparation of such registration  statement,  and in
each  such  case  RHI  was  afforded  the  opportunity  to  include  Registrable
Securities  in such  registration  pursuant to Section 2.2 (unless the  managing
underwriter  for such  registration  is of the opinion that such inclusion would
adversely affect the Company's  ability to complete its underwritten  offering).
Notwithstanding  anything in this Section 2.1 to the contrary, in no event shall
the  Company  be  required  to effect  (i) in the  aggregate,  more  than  three
registrations pursuant to this Section 2.1 (other than registrations  pertaining
to Special  Securities,  which shall be  unlimited  in number and not  otherwise
reduce the number of  registrations  available  to the Company  pursuant to this
Section 2.1) and (ii) more than one registration pursuant to this Section 2.1 in
any 180-day period (other than registrations  pertaining to Special  Securities,
which shall not affect or be affected by this clause (ii)).

                            2.1.8 Right to Purchase in Lieu of Registration.  If
the Company receives a request for a Demand registration and the Company desires
not to comply with such request,  then the Company may purchase all but not less
than  all of the  Registrable  Securities  proposed  to be  disposed  of in such
request (the "Redeemable Shares") by delivering to RHI a notice of the





                                       -6-



Company's  election to purchase such  Registrable  Securities  (the  "Redemption
Notice")  within seven (7) days of receipt by the Company of the request for the
Demand  registration  pursuant to Section 2.1.1. Upon issuance of the Redemption
Notice,  the Company shall be irrevocably  committed to purchase the Registrable
Securities on the terms set forth herein.  The purchase price to be paid for the
Registrable Securities shall be the Closing Price on the Trading Day immediately
prior to the date the Company  receives the notice for the Demand  registration;
provided, that in the event the Registrable Securities are not listed and traded
on any  national  securities  exchange  or on NASDAQ  (as  defined  below),  the
purchase  price  shall be  established  by the written  opinion of a  nationally
recognized  investment  banking firm selected by RHI delivered to the Company at
time of the request for a Demand registration. The term "Trading Day" shall mean
a day  on  which  the  principal  national  securities  exchange  on  which  the
Registrable  Securities in question shall be listed or admitted to trading shall
be open for the transaction of business or, if the Registrable  Securities shall
not be listed or admitted to trading on any national  securities  exchange,  any
day on which trading  takes place in the  over-the-counter  market.  The Company
shall purchase the  Registrable  Securities  within thirty (30) business days of
the issuance of the  Redemption  Notice by delivering the purchase price in cash
to RHI against delivery of the Registrable Securities. "Closing Price" means the
last  sale  price,  regular  way,  as  reported  in the  principal  consolidated
transaction  reporting  system with respect to securities  listed or admitted to
trading on the principal national  securities  exchange on which the Registrable
Securities  shall be listed  or  admitted  to  trading  or,  if the  Registrable
Securities shall not be listed or admitted to trading on any national securities
exchange,  the last quoted  price or, if not so quoted,  the average of the high
bid and low asked  prices in the  over-the-counter  market,  as  reported by the
National   Association  of  Securities   Dealers  Automated   Quotations  System
("NASDAQ") or such other system then in use.

                  2.2  Piggyback Registration.

                            2.2.1 Right to Include  Registrable  Securities.  If
the Company at any time  proposes to register  any of its  securities  under the
Securities  Act by  registration  on Forms S-1,  S-2,  S-3 or any  successor  or
similar  form(s) (except  registrations  on such Forms or similar form(s) solely
for  registration of securities in connection with (i) an employee  benefit plan
or  dividend  reinvestment  plan or a  merger  or  consolidation  or  (ii)  debt
securities which are not convertible into Common Stock), whether or not for sale
for its own  account,  it shall,  subject  to Section  2.8,  each such time give
written notice to RHI of its intention to do





                                       -7-


so and of RHI's  rights  under  this  Section  2.2 at least 15 days prior to the
filing of a registration  statement with respect to such  registration  with the
Commission.  Upon the written request of RHI made as promptly as practicable and
in any event within 5 business days after the receipt of any such notice,  which
request shall specify the Registrable  Securities  intended to be disposed of by
RHI, the Company  shall,  subject to Section 2.7, use its best efforts to effect
the  registration  under the Securities Act of all Registrable  Securities which
the  Company has been so  requested  to  register  by RHI;  provided,  that with
respect  to  registrations  effected  for  the  account  of  another  holder  of
securities of the Company,  RHI's rights to include Registrable  Securities will
be subject to the consent of such other holder under  agreements  existing as of
the date of this Agreement; provided, further, that if, at any time after giving
written  notice of its  intention  to register any  securities  and prior to the
effective  date of the  registration  statement  filed in  connection  with such
registration,  the Company shall  determine for any reason not to register or to
delay  registration of such securities,  the Company may, at its election,  give
written  notice  of  such  determination  to  RHI  and  (i)  in  the  case  of a
determination  not to register,  shall be relieved of its obligation to register
any Registrable  Securities in connection with such  registration  (but not from
any  obligation  of the Company to pay the  Registration  Expenses in connection
therewith), without prejudice; provided, however, that RHI may request that such
registration be effected as a registration  under Section 2.1 hereof and (ii) in
the case of a determination  to delay  registering,  shall be permitted to delay
registering  any  Registrable  Securities  for the same  period  as the delay in
registering such other securities.  No registration  effected under this Section
2.2 shall relieve the Company of its obligation to effect any registration  upon
demand under  Section 2.1. The Company  shall pay all  Registration  Expenses in
connection with  registration of Registrable  Securities  requested  pursuant to
this Section 2.2.

                            2.2.2    Priority   in   Piggyback    Registrations.
Notwithstanding  anything  in  paragraph  2.2.1  above to the  contrary,  if the
managing  underwriter of any  underwritten  offering shall inform the Company by
letter of its belief that the number or type of Registrable Securities requested
to be included in such  registration  would materially and adversely affect such
offering, then the Company shall include in such registration,  to the extent of
the number and type  which the  Company is so advised  can be sold in (or during
the time of) such offering,  first, all securities proposed by the Company to be
sold for its own account or by the holder of  securities  who initiated a demand
registration,   and  second,   by  reducing  the  other  securities   (including
Registrable Securities to be sold by other holders of securities (including





                                       -8-


RHI)) in  proportion  to the number of  securities  proposed  to be sold in such
offering by such holders.

                  2.3  Registration Procedures.

                            2.3.1 In  connection  with the  registration  of any
Registrable  Securities under the Securities Act as provided in Sections 2.1 and

                            (i)  prepare  and  file  with  the   Commission  the
requisite  registration statement to effect such registration and thereafter use
its best  efforts  to cause  such  registration  statement  to become and remain

may  discontinue any  registration  of its securities  which are not Registrable
Securities at any time prior to the effective date of the registration statement
relating thereto;

                            (ii)  prepare  and  file  with the  Commission  such
amendments  and  supplements to such  registration  statement and the prospectus
used in  connection  therewith  as may be  necessary  to keep such  registration
statement effective and to comply with the provisions of the Securities Act with
respect  to the  disposition  of all  Registrable  Securities  covered  by  such
registration  statement for such period as shall be required for the disposition
of all of such  Registrable  Securities;  provided,  that such  period  need not
exceed 90 days;

                            (iii) furnish to RHI such number of conformed copies
of such registration statement and of each such amendment and supplement thereto
(in each case including all  exhibits),  such number of copies of the prospectus
contained in such registration  statement (including each preliminary prospectus
and any summary  prospectus) and any other prospectus filed under Rule 424 under
the Securities Act, in conformity  with the  requirements of the Securities Act,
and such other documents, as RHI may reasonably request;

                            (iv) use its best efforts (x) to register or qualify
all Registrable  Securities and other  securities  covered by such  registration
statement  under such other  securities  or Blue Sky laws of such  States of the
United  States of America  where an exemption is not  available and as RHI shall
reasonably request, (y) to keep such registration or qualification in effect for
so long as such registration  statement  remains in effect,  and (z) to take any
other  action  which may  reasonably  be necessary or advisable to enable RHI to
consummate the disposition in such jurisdictions of the





                                       -9-


securities  to be sold by RHI,  except that the  Company  shall not for any such
purpose be required to qualify generally to do business as a foreign corporation
in any  jurisdiction  wherein it would  not,  but for the  requirements  of this
paragraph (iv), be obligated to be so qualified or to consent to general service
of process in any such jurisdiction;

                            (v) use its best  efforts  to cause all  Registrable
Securities  covered by such  registration  statement  to be  registered  with or
approved by such other federal or state governmental  agencies or authorities as
may be  necessary in the opinion of counsel to the Company and counsel to RHI to
consummate the  disposition of such  Registrable  Securities in accordance  with
their intended method of disposition;

                            (vi)  furnish to RHI and its  underwriters,  if any,
(x) an opinion of counsel for the Company,  and (y) a "comfort" letter signed by
the independent  public  accountants who have certified the Company's  financial
statements included or incorporated by reference in such registration statement,
each covering  substantially  the same matters with respect to such registration
statement  (and  the  prospectus  included  therein)  and,  in the  case  of the
accountant's  comfort letter,  with respect to events  subsequent to the date of
such financial  statements,  as are customarily  covered in opinions of issuer's
counsel and in  accountant's  comfort letters  delivered to the  underwriters in
underwritten  public  offerings of securities (and dated the dates such opinions
and comfort letters are customarily dated);

                            (vii) notify RHI when a prospectus  relating thereto
is required to be delivered  under the Securities  Act, upon discovery  that, or
upon the happening of any event as a result of which, the prospectus included in
such registration  statement, as then in effect, includes an untrue statement of
a  material  fact or omits to state  any  material  fact  required  to be stated
therein or necessary to make the statements therein not misleading, in the light
of the  circumstances  under  which  they were made,  and at the  request of RHI
promptly prepare and furnish to it a reasonable number of copies of a supplement
to or an amendment of such prospectus as may be necessary so that, as thereafter
delivered  to the  purchasers  of such  securities,  such  prospectus  shall not
include an untrue  statement of a material fact or omit to state a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading in the light of the circumstances under which they were made;

                            (viii) otherwise use its best efforts to comply with
all applicable rules and regulations of the Commission, and make





                                      -10-


available  to its  security  holders,  as soon  as  reasonably  practicable,  an
earnings  statement  covering the period of at least twelve months, but not more
than eighteen  months,  beginning  with the first full calendar  month after the
effective date of such registration  statement,  which earnings  statement shall
satisfy  the  provisions  of Section  11(a) of the  Securities  Act and Rule 158
promulgated thereunder, and promptly furnish the same to RHI;

                            (ix)  provide and cause to be  maintained a transfer
agent  and  registrar  (which,  in  each  case,  may be  the  Company)  for  all
Registrable  Securities covered by such registration  statement from and after a
date not later than the effective date of such registration; and

                            (x) use its best  efforts  to list  all  Registrable
Securities  covered by such  registration  statement on any national  securities
exchange or over-the-counter  market, if any, on which Registrable Securities of
the  same  class  and,  if  applicable,  series,  covered  by such  registration
statement are then listed.

                  The  Company  may  require  RHI to furnish  the  Company  such
information  regarding RHI and the distribution of RHI's Registrable  Securities
as the Company may from time to time reasonably request in writing.

                  RHI agrees that upon receipt of any notice from the Company of
the happening of an event of the kind described in Section 2.3.1(vii),  RHI will
forthwith discontinue its disposition of Registrable  Securities pursuant to the
registration  statement  relating  to such  Registrable  Securities  until RHI's
receipt of the copies of the supplemented or amended prospectus  contemplated by
Section  2.3.1(vii) and, if so directed by the Company,  RHI will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies,
then in  RHI's  possession,  of the  prospectus  relating  to  such  Registrable
Securities current at the time of receipt of such notice.

                  2.4  Underwritten Offerings.

                            2.4.1 Requested Underwritten Offerings. If requested
by  the  underwriters  for  any  underwritten  offering  by  RHI  pursuant  to a
registration  requested  under  Section  2.1,  the  Company  will  enter into an
underwriting agreement with such underwriters for such offering,  such agreement
to be reasonably  satisfactory in substance and form to the Company, RHI and the
underwriters,  and to contain such representations and warranties by the Company
and RHI and such other terms as are  generally  prevailing in agreements of that
type, including, without limitation, indemnities to the





                                      -11-


effect and to the extent  provided in Section 2.8. RHI will  cooperate  with the
Company  in  the  negotiation  of  the  underwriting  agreement  and  will  give
consideration  to the reasonable  suggestions of the Company  regarding the form
and substance thereof. RHI shall be a party to such underwriting agreement.  RHI
shall not be required to make any representations or warranties to or agreements
with the Company or the underwriters other than  representations,  warranties or
agreements regarding RHI, RHI's Registrable Securities, RHI's intended method of
distribution  and any other  representations  or  warranties  required by law or
customarily given by selling shareholders in an underwritten public offering.

                            2.4.2  Piggyback  Underwritten   Offerings.  If  the
Company  proposes to register any of its securities  under the Securities Act as
contemplated  by Section 2.2 and such  securities  are to be  distributed  by or
through one or more  underwriters,  the Company will, subject to Section 2.2 and
Section 2.7 hereof,  if  requested  by RHI,  arrange  for such  underwriters  to
include all the  Registrable  Securities to be offered and sold by RHI among the
securities of the Company to be distributed by such underwriters (subject to the
provisio  stated in Section 2.2).  RHI shall become a party to the  underwriting
agreement negotiated between the Company and such underwriters. RHI shall not be
required to make any  representations  or warranties  to or agreements  with the
Company or the underwriters other than representations, warranties or agreements
regarding  RHI,  RHI's  Registrable  Securities  and  RHI's  intended  method of
distribution  or any other  representations  or  warranties  required  by law or
customarily given by selling shareholders in an underwritten public offering.

                            2.4.3 Holdback Agreements.

                            (i) If any  registration  of Registrable  Securities
(other than special  securities)  shall be in  connection  with an  underwritten
public  offering,  RHI agrees not to effect  any  public  sale or  distribution,
including  any sale  pursuant  to Rule 144  under  the  Securities  Act,  of any
Registrable  Securities,  and not to effect any such public sale or distribution
of any other equity security of the Company or of any security  convertible into
or  exchangeable  or exercisable for any equity security of the Company (in each
case,  other than as part of such  underwritten  public  offering) during the 15
days prior to, and during the 90-day period  beginning on, the effective date of
such  registration  statement,  provided that RHI has received written notice of
such registration at least 15 days prior to such effective date.

                            (ii) If any  registration of Registrable  Securities
(other than special securities) shall be in connection with an





                                      -12-


underwritten  public  offering,  the Company agrees (x) not to effect any public
sale  or  distribution  of any  of  its  equity  securities  or of any  security
convertible  into or  exchangeable or exercisable for any equity security of the
Company  (other  than in  connection  with any  employee  stock  option or other
benefit  plan)  during  the 15 days  prior to,  and  during  the  90-day  period
beginning on the effective date of such  registration  statement (except as part
of such  registration) and (y) that any agreement entered into after the date of
this  Agreement  pursuant  to which  the  Company  issues or agrees to issue any
privately placed equity securities shall contain a provision under which holders
of such  securities  agree not to effect any public sale or  distribution of any
such  securities  during the period  referred  to in the  foregoing  clause (x),
including any sale pursuant to Rule 144 under the Securities Act (except as part
of such  registration,  if permitted),  if such holder is  participating  in the
offering pursuant to such registration.

                  2.5 Preparation;  Reasonable Investigation. In connection with
the preparation and filing of each  registration  statement under the Securities
Act pursuant to this Agreement, the Company will give RHI, its underwriters,  if
any, and their respective counsel and accountants the opportunity to participate
in the preparation of such  registration  statement,  each  prospectus  included
therein or filed with the Commission,  and each amendment  thereof or supplement
thereto,  and give each of them such  access  to its  books  and  records,  such
opportunities  to discuss  the  business of the Company  with  officers  and the
independent  public  accountants who have certified its financial  statements as
shall be necessary,  in the opinion of RHI's and such  underwriters'  respective
counsel,  to  conduct a  reasonable  investigation  within  the  meaning  of the
Securities  Act.  Any  expenses  incurred  by RHI in  connection  with  any such
investigation shall be borne by RHI.

                  2.6 Limitations,  Conditions and Qualifications to Obligations
under  Registration  Covenants.  The  obligations of the Company to use its best
efforts  to  cause  the  Registrable  Securities  to  be  registered  under  the
Securities Act are subject to each of the following limitations,  conditions and
qualifications:

                  In  addition  to its rights  under  Section  2.1.8 the Company
shall be entitled to postpone for a reasonable period of time (but not exceeding
60 days) the  filing of any  registration  statement  otherwise  required  to be
prepared and filed by it pursuant to Section 2.1 if the Company  determines,  in
its reasonable  judgment,  that such  registration  and offering would interfere
with any  financing,  acquisition,  corporate  reorganization  or other material
transaction involving the Company or any of its Affiliates or would





                                      -13-


require  premature  disclosures  thereof and promptly give RHI written notice of
such  determination,  containing  a general  statement  of the  reasons for such
postponement and an approximation of the anticipated delay. If the Company shall
so postpone the filing of a registration statement,  RHI shall have the right to
withdraw the request for  registration  by giving  written notice to the Company
within 30 days after receipt of the notice of postponement  and, in the event of
such withdrawal,  such request shall not be counted for purposes of the requests
for registration to which RHI is entitled pursuant to Section 2.1 hereof.

                  2.7  Indemnification.

                           2.7.1  Indemnification by the Company.  In  the event
of any  registration  of any securities of the Company under the Securities Act,
the Company will, and hereby does,  indemnify and hold harmless,  in the case of
any  registration  statement  filed  pursuant  to Section 2.1 or 2.2,  RHI,  its
directors,  officers, partners, agents, and affiliates and each other Person who
participates  as an underwriter  in the offering or sale of such  securities and
each other Person,  if any, who controls RHI or any such underwriter  within the
meaning  of  the  Securities  Act,  insofar  as  losses,  claims,   damages,  or
liabilities  (or actions or  proceedings,  whether  commenced or threatened,  in
respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue  statement of any material fact contained in any  registration  statement
under which such  securities  were  registered  under the  Securities  Act,  any
preliminary  prospectus,  final  prospectus,  or  summary  prospectus  contained
therein,  or any  amendment or  supplement  thereto,  or any omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the statements  therein in light of the circumstances in which
they were made not misleading,  and the Company will reimburse RHI and each such
director,  officer,  partner,  agent or affiliate,  underwriter  and controlling
Person  for any  legal or any  other  expenses  reasonably  incurred  by them in
connection  with  investigating  or defending any such loss,  claim,  liability,
action or proceeding; provided, that the Company shall not be liable in any such
case to the extent that any such loss,  claim,  damage,  liability (or action or
proceeding  in respect  thereof)  or  expense  arises out of or is based upon an
untrue  statement or alleged  untrue  statement or omission or alleged  omission
made in such  registration  statement,  any such preliminary  prospectus,  final
prospectus, summary prospectus,  amendment or supplement in reliance upon and in
conformity  with  written  information  furnished  to  the  Company  through  an
instrument duly executed by or on behalf of RHI or such underwriter, as the case
may be, specifically  stating that it is for use in the preparation thereof; and
provided, further,





                                      -14-



that the Company shall not be liable to RHI or any Person who participates as an
underwriter  in the  offering  or sale of  Registrable  Securities  or any other
person,  if any, who controls RHI or such underwriter  within the meaning of the
Securities  Act,  in any such  case to the  extent  that any such  loss,  claim,
damage, liability (or action or proceeding in respect thereof) or expense arises
out of such Person's failure to send or give a copy of the final prospectus,  as
the same may be then supplemented or amended,  to the Person asserting an untrue
statement  or alleged  untrue  statement  or omission or alleged  omission at or
prior to the written confirmation of the sale of Registrable  Securities to such
Person if such  statement or omission was corrected in such final  prospectus so
long as such final prospectus,  and any amendments or supplements thereto,  have
been furnished to such  underwriter or RHI, as applicable.  Such indemnity shall
remain in full force and effect  regardless of any  investigation  made by or on
behalf of RHI or any such  director,  officer,  partner,  agent or  affiliate or
controlling Person and shall survive the transfer of such securities by RHI.

                            2.7.2  Indemnification  by RHI.  If any  Registrable
Securities are included in any registration statement, each of TFC and RHI will,
and each hereby does, jointly and severally  indemnify and hold harmless (in the
same  manner  and to the same  extent as set forth in Section  2.7.1  above) the
Company, and each director of the Company,  each officer of the Company and each
other  Person,  if any,  who  controls  the  Company  within the  meaning of the
Securities  Act,  with  respect  to any  statement  or alleged  statement  in or
omission or alleged omission from such registration  statement,  any preliminary
prospectus,  final prospectus or summary prospectus  contained  therein,  or any
amendment or  supplement  thereto,  if such  statement  or alleged  statement or
omission or alleged  omission was made in reliance upon and in  conformity  with
written information furnished to the Company through an instrument duly executed
by TFC or RHI specifically stating that it is for use in the preparation of such
registration  statement,   preliminary  prospectus,  final  prospectus,  summary
prospectus, amendment or supplement.

                            2.7.3 Notice of Claims,  Etc. Promptly after receipt
by an  indemnified  party  of  notice  of  the  commencement  of any  action  or
proceeding  involving a claim  referred to in the  preceding  paragraphs of this
Section 2.7, such indemnified party will, if a claim in respect thereof is to be
made against an  indemnifying  party,  immediately  give  written  notice to the
latter of the commencement of such action;  provided,  however, that the failure
of any indemnified party to give notice as provided herein shall not relieve the
indemnifying  party of its  obligations  under the preceding  paragraphs of this
Section 2.7, except to the extent





                                      -15-


that the  indemnifying  party is  actually  prejudiced  by such  failure to give
notice. In case any such action is brought against an indemnified party,  unless
in such indemnified  party's reasonable  judgment a conflict of interest between
such  indemnified and  indemnifying  parties may exist in respect of such claim,
the  indemnifying  party shall be entitled to  participate  in and to assume the
defense thereof, jointly with any other indemnifying party similarly notified to
the  extent  that it may wish,  with  counsel  reasonably  satisfactory  to such
indemnified  party,  and  after  notice  from  the  indemnifying  party  to such
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof other than reasonable  costs related to the indemnified  party's
cooperation with the  indemnifying  party,  unless in such  indemnified  party's
reasonable  judgment  a  conflict  of  interest  between  such  indemnified  and
indemnifying parties arises in respect of such claim after the assumption of the
defense thereof. No indemnifying party shall be liable for any settlement of any
action or proceeding  effected without its written consent,  which consent shall
not be unreasonably  withheld.  No indemnifying party shall, without the consent
of the  indemnified  party,  consent to entry of any  judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the  claimant  or  plaintiff  to such  indemnified  party of a release  from all
liability in respect to such claim or litigation.

                            2.7.4 Contribution.  If the indemnification provided
for in this  Section  2.7  shall  for  any  reason  be  held  by a  court  to be
unavailable to an  indemnified  party under  paragraph  2.7.1 or 2.7.2 hereof in
respect  of any loss,  claim,  damage or  liability,  or any  action in  respect
thereof,  then, in lieu of the amount paid or payable under  paragraph  2.7.1 or
2.7.2 hereof,  the indemnified party and the indemnifying  party under paragraph
2.7.1 or 2.7.2 hereof shall contribute to the aggregate losses,  claims, damages
and  liabilities  (including  legal or other  expenses  reasonably  incurred  in
connection  with   investigating  the  same),  (i)  in  such  proportion  as  is
appropriate to reflect the relative fault of the Company on one hand and TFC and
RHI on the other which  resulted in such loss,  claim,  damage or liability,  or
action in respect  thereof,  with respect to the  statements or omissions  which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations or (ii) if the allocation
provided by  paragraph  (i) above is not  permitted by  applicable  law, in such
proportion as shall be appropriate to reflect the relative  benefits received by
the  Company  on one hand and TFC and RHI on the  other.  No  Person  guilty  of
fraudulent misrepresentation (within the





                                      -16-


meaning of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.  In addition, no Person
shall be  obligated  to  contribute  hereunder  any  amounts in payment  for any
settlement of any action or claim, effected without such Person's consent, which
consent shall not be unreasonably withheld.

                            2.7.5  Other  Indemnification.  Indemnification  and
contribution  similar to that  specified  in the  preceding  paragraphs  of this
Section 2.7 (with appropriate  modifications)  shall be given by the Company and
TFC and RHI with respect to any required  registration or other qualification of
securities  under any  federal or state law or  regulation  of any  governmental
authority other than the Securities Act.

                            2.7.6 Indemnification  Payments. The indemnification
and contribution required by this Section 2.7 shall be made by periodic payments
of the amount thereof during the course of the investigation or defense,  as and
when bills are received or expense, loss, damage or liability is incurred.

                            2.7.7 Disclosure of Results of  Investigation.  Each
of TFC and RHI covenants  and agrees that if in the course of its  investigation
of the Company  anything comes to its attention that indicates there is or there
could become a breach of the Company's representations and warranties, covenants
and  agreements  contained  in any  underwriting  agreement,  TFC and RHI  shall
promptly  notify the  Company of such  matter.  Failure to so notify the Company
shall cause TFC and RHI to lose its right to  indemnification  under Section 2.7
with respect to such discovered matter.

         3. Rule 144.  With a view to making  available  the benefits of certain
rules and regulations of the Commission which may at any time permit the sale of
the Registrable  Securities to the public without registration,  after such time
as a public market exists for its Common Stock, the Company agrees to:

                  (a)  use  its  best  efforts  to  facilitate  the  sale of the
Registrable  Securities to the public, without registration under the Securities
Act,  pursuant to Rule 144 promulgated  under the Securities Act,  provided that
this shall not require the Company to file reports under the  Securities Act and
the Exchange Act at any time prior to the Company's being otherwise  required to
file such reports;

                  (b) make and keep public information available, as those terms
are understood and defined in Rule 144  promulgated  under the Securities Act at
all times after ninety (90) days after the





                                      -17-


effective date of the first  registration  under the Securities Act filed by the
Company for an offering of its securities to the general public;

                  (c) use its best efforts to then file with the Commission in a
timely manner all reports and other documents  required of the Company under the
Securities Act and the Exchange Act; and

                  (d) deliver a written  statement as to whether it has complied
with such requirements of this Section, to RHI upon RHI's request.

         4.       LEGEND.  Any certificate evidencing Registrable
Securities shall bear the following legend:

         "THE  SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE ARE
         SUBJECT TO A REGISTRATION RIGHTS AGREEMENT,  DATED AS OF

         SHALL BE FURNISHED WITHOUT CHARGE BY SHARED TECHNOLOGIES
         INC. TO  THE  HOLDER  HEREOF  UPON SUCH HOLDER'S WRITTEN
         REQUEST."

         5.  MODIFICATION;  WAIVERS.  This  Agreement may be modified or amended
only with the written  consent of each party  hereto.  No party  hereto shall be
released from its obligations hereunder without the written consent of the other
party.  The  observance  of any term of this  Agreement  may be  waived  (either
generally or in a particular instance and either retroactively or prospectively)
by the party  entitled  to  enforce  such  term,  but any such  waiver  shall be
effective  only if in a writing signed by the party against which such waiver is
to be asserted.  Except as otherwise  specifically  provided herein, no delay on
the part of any  party  hereto  in  exercising  any  right,  power or  privilege
hereunder shall operate as a waiver thereof, nor shall any waiver on the part of
any party hereto of any right, power or privilege  hereunder operate as a waiver
of any other right, power or privilege hereunder nor shall any single or partial
exercise  of any  right,  power or  privilege  hereunder  preclude  any other or
further exercise thereof or the exercise of any other right,  power or privilege
hereunder.

         6. ENTIRE AGREEMENT. This Agreement represents the entire understanding
and  agreement  between the parties  hereto with  respect to the subject  matter
