and  the   investors   listed  on  the  Schedule  of  Buyers   attached   hereto
(individually, a "BUYER" and collectively, the "BUYERS").

            WHEREAS:

            A.    The Company and the Buyers are executing and  delivering  this
Agreement in reliance upon the exemption from securities  registration  afforded

as amended and the rules and  regulations  thereunder,  or any  similar  statute
(collectively, the "1933 ACT");

            B.    The Company has  authorized  the  following  new series of its
Preferred  Stock,  par value  $1.00  per  share  (the  "PREFERRED  STOCK"):  the
Company's Series C Convertible  Preferred Stock (the "PREFERRED SHARES"),  which
shall be convertible  into shares of the Company's Common Stock, par value $0.01
per share (the "COMMON  STOCK") (as  converted,  the  "CONVERSION  SHARES"),  in
accordance   with  the  terms  of  the  Company's   Certificate  of  Designation
substantially  in the form  attached  hereto as Exhibit A (the  "CERTIFICATE  OF
DESIGNATION");

            C.    The Company  has  authorized  the  issuance  of  Warrants,  in
substantially  the form  attached  hereto  as  Exhibit  B (the  "WARRANTS"),  to
purchase shares of Common Stock (as exercised, the "WARRANT SHARES").

            D.    The Buyers  wish to  purchase,  upon the terms and  conditions
stated in this  Agreement,  initially  an  aggregate  of 5,000 of the  Preferred
Shares and  Warrants  exercisable  for the  purchase of an  aggregate of 200,000
shares of Common  Stock,  at the rate of one  Preferred  Share and a Warrant  to
purchase 40 shares of Common  Stock for each $1,000 to be invested by such Buyer
as set forth opposite each Buyer's name on the Schedule of Buyers;

            E.    Contemporaneously  with the  execution  and  delivery  of this
Agreement, the parties hereto are executing and delivering a Registration Rights
Agreement   substantially  in  the  form  attached  hereto  as  Exhibit  C  (the
"REGISTRATION  RIGHTS  AGREEMENT")  pursuant  to which the Company has agreed to
provide  certain  registration  rights  under  the  1933 Act and the  rules  and
regulations promulgated thereunder, and applicable state securities laws.

            NOW THEREFORE, the Company and the Buyers hereby agree as follows:

                        Common  Stock  for each  $1,000 to be  invested  by such
                        Buyer,  as set forth  opposite  each Buyer's name on the

                        Designation,  but any such  additional days shall not be
                        included in any time frame  contained in any Transaction

                        Preferred  Shares and  Warrants to be issued and sold to
                        such  Buyer  at  the  Closing,   by  wire   transfer  of
                        immediately  available  funds  in  accordance  with  the

                        certificates  (in the  denominations as such Buyer shall
                        request) (the "STOCK  CERTIFICATES")  representing  such
                        number  of the  Preferred  Shares  and (y) the  Warrants
                        which such Buyer is then purchasing,  each duly executed
                        on behalf of the Company and  registered  in the name of
                        such Buyer or its designee.

            2.    BUYER'S REPRESENTATIONS AND WARRANTIES.

                  Each Buyer represents and warrants with respect to only itself
that:

                  a.    INVESTMENT   PURPOSE.   Such  Buyer  is  acquiring   the
Preferred Shares and Warrants (and intends to acquire the Conversion  Shares and
the Warrant Shares) for its own account



                                       -2-

<PAGE>



for  investment  only and not with a view  towards,  or for resale in connection
with,  the public  sale or  distribution  thereof  (the  Preferred  Shares,  the
Warrants,  the  Conversion  Shares and the  Warrant  Shares  being  collectively
referred to herein as the "SECURITIES").

                  b.    INVESTOR STATUS.  Raphael L.P. and Ramius Fund, Ltd. are
each a  "qualified  institutional  buyer",  as  that  term  is  defined  in Rule
144A(a)(1)  promulgated  under the 1933 Act and  Leonardo,  L.P.,  GAM Arbitrage
Investments,  Inc. and AG Super Fund  International  Partners,  L.P. are each an
"accredited investor", as that term is defined in Rule 501(a)(3) of Regulation D
promulgated  under the 1933 Act. No Buyer is a resident of or  domiciled  in the
United  States.  Such  Buyer was not  offered  securities  or  solicited  by the
Company,  any  proposed  underwriter  or any other  person  with  respect to the
Company's Registration Statement (since withdrawn) filed on October 22, 1997 and
has not reviewed nor been  provided  with a copy of the  preliminary  prospectus
contained therein or the preliminary prospectus dated November 7, 1997.

                  c.    RELIANCE ON EXEMPTIONS.  Such Buyer understands that the
Securities  are being offered and sold to it in reliance on specific  exemptions
from the registration requirements of United States federal and state securities
laws and that the Company is relying in part upon the truth and accuracy of, and
such Buyer's  compliance  with,  the  representations,  warranties,  agreements,
acknowledgments  and  understandings  of such Buyer set forth herein in order to
determine the  availability of such exemptions and the eligibility of such Buyer
to acquire such securities.

                  d.    INFORMATION.  Such Buyer and its advisors,  if any, have
been afforded the opportunity to review all materials  relating to the business,
finances and  operations of the Company and materials  relating to the offer and
sale of the Securities  which have been  requested by such Buyer,  including all
SEC Documents (as defined below). Such Buyer and its advisors, if any, have been
afforded the opportunity to review the Company's  Annual Report on Form 10-K for
the year ended June 27, 1997 (as amended), Quarterly Report on Form 10-Q for the
quarter ended September 26, 1997,  Proxy Statement being used in connection with
the Company's  Annual Meeting of Stockholders to be held on January 21, 1998 and
Current  Reports on Form 8-K dated (date of earliest  event  reported)  July 29,
1997 and January 6, 1998, each of which have been filed as SEC Documents and the
"Risk  Factors"  annexed  hereto  as  Exhibit  D,  and  has  been  afforded  the
opportunity  to ask  questions of the Company.  Neither such  inquiries  nor any
other due diligence  investigations  conducted by such Buyer or its advisors, if
any, or its representatives  shall modify, amend or affect such Buyer's right to
rely on the  Company's  representations  and  warranties  contained in Section 3
below. Such Buyer  understands that its investment in the Securities  involves a
high degree of risk. Such Buyer has sought such accounting, legal and tax advice
as it has  considered  necessary to make an informed  investment  decision  with
respect to its acquisition of the Securities.

                  e.    NO GOVERNMENTAL  REVIEW.  Such Buyer understands that no
United States  federal or state agency or any other  government or  governmental
agency has passed on or made any recommendation or endorsement of the Securities
or the fairness or suitability of the investment in the Securities nor have such
authorities  passed  upon  or  endorsed  the  merits  of  the  offering  of  the
Securities.


                                       -3-

<PAGE>




                  f.    TRANSFER OR RESALE.  Such Buyer  understands that except
as provided in the Registration  Rights  Agreement:  (i) the Securities have not
been and are not being  registered  under  the 1933 Act or any state  securities
laws, and may not be offered for sale, sold,  assigned or transferred unless (A)
subsequently  registered thereunder,  (B) such Buyer shall have delivered to the
Company an opinion of counsel,  in a generally  acceptable  form,  to the effect
that such Securities to be sold,  assigned or transferred may be sold,  assigned
or  transferred  pursuant to an exemption  from such  registration,  or (C) such
Buyer provides the Company with reasonable assurance that such Securities can be
sold,  assigned or transferred  pursuant to Rule 144 promulgated  under the 1933
Act (or a successor rule thereto) ("RULE 144");  (ii) any sale of the Securities
made in  reliance on Rule 144 may be made only in  accordance  with the terms of
Rule  144  and  further,  if  Rule  144 is not  applicable,  any  resale  of the
Securities  under  circumstances in which the seller (or the person through whom
the sale is made) may be deemed to be an underwriter (as that term is defined in
the 1933 Act) may require  compliance  with some other  exemption under the 1933
Act or the rules and  regulations of the SEC  thereunder;  and (iii) neither the
Company nor any other person is under any obligation to register such Securities
under the 1933 Act or any state  securities laws or to comply with the terms and
conditions of any exemption thereunder.

                  g.    LEGENDS. Such Buyer understands that the certificates or
other instruments  representing the Preferred Shares and the Warrants and, until
such time as the sale of the  Conversion  Shares and  Warrant  Shares  have been
registered  under  the  1933  Act as  contemplated  by the  Registration  Rights
Agreement,  the stock  certificates  representing the Conversion  Shares and the
Warrant Shares,  except as set forth below,  shall bear a restrictive  legend in
substantially the following form or, in the case of the Warrants,  the legend on
the face of the  Warrant as set forth in Exhibit B hereto  (and a  stop-transfer
order may be placed against transfer of such stock certificates):

            THE  SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT  BEEN
REGISTERED  UNDER THE  SECURITIES ACT OF 1933, AS AMENDED,  OR APPLICABLE  STATE
SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
OFFERED FOR SALE,  SOLD,  TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
REGISTRATION  STATEMENT FOR THE SECURITIES  UNDER THE SECURITIES ACT OF 1933, AS
AMENDED,  OR APPLICABLE STATE  SECURITIES  LAWS, OR AN OPINION OF COUNSEL,  IN A
GENERALLY  ACCEPTABLE FORM, THAT  REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR
APPLICABLE STATE SECURITIES LAWS.

The legend  set forth  above  shall be removed  and the  Company  shall  issue a
certificate without such legend to the holder of the Securities upon which it is
stamped,  if,  unless  otherwise  required by state  securities  laws,  (i) such
Securities are registered for sale under the 1933 Act, (ii) in connection with a
sale  transaction,  such holder provides the Company with an opinion of counsel,
in a generally acceptable form, to the effect that a public sale,  assignment or
transfer of such Securities may be made without registration under the 1933 Act,
or (iii) such holder provides the Company with  reasonable  assurances that such
Securities can be sold pursuant to paragraph (k) of Rule 144. Each


                                       -4-

<PAGE>



Buyer acknowledges, covenants and agrees to sell the Securities represented by a
certificate(s)  from which the legend has been  removed,  only pursuant to (i) a
registration statement that is effective and current under the 1933 Act, or (ii)
advice of counsel that such sale is exempt from registration required by Section
5 of the 1933 Act.

                  h.    AUTHORIZATION; ENFORCEMENT. This Agreement has been duly
and validly authorized,  executed and delivered on behalf of such Buyer and is a
valid and binding  agreement of such Buyer  enforceable  in accordance  with its
terms,  subject  as to  enforceability  to general  principles  of equity and to
applicable bankruptcy, insolvency,  reorganization,  moratorium, liquidation and
other  similar laws  relating to, or affecting  generally,  the  enforcement  of
applicable creditors' rights and remedies.

                  i.    RESIDENCY.  Such Buyer is a resident of the jurisdiction
specified in the Schedule of Buyers.

                  j.    SECTION 9 OF THE  SECURITIES  EXCHANGE ACT. So long as a
Buyer holds any Preferred  Shares,  such Buyer will comply at all times with the
provisions of Section 9 of the Securities  Exchange Act of 1934, as amended (the
"1934 ACT"), and the rules  promulgated  thereunder with respect to transactions
involving the securities of the Company.

            3.    REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

                  The  Company  represents  and  warrants  to each of the Buyers
that:

                  a.    ORGANIZATION  AND  QUALIFICATION.  The  Company  and its
subsidiaries other than subsidiaries which, if considered as a single subsidiary
would not  constitute  a  "significant  subsidiary"  within the  meaning of Rule
1-02(w)  of  Regulation  S-X   promulgated  by  the  SEC  (a  complete  list  of
subsidiaries  not so excluded is set forth in Schedule  3(a);  all references in
this Agreement to subsidiaries  are limited to those  subsidiaries  set forth on
Schedule  3(a)) are  corporations  duly  organized and validly  existing in good
standing under the laws of the jurisdiction in which they are incorporated,  and
have the requisite corporate power to own their properties and to carry on their
business as now being  conducted.  Each of the Company and its  subsidiaries  is
duly  qualified as a foreign  corporation to do business and is in good standing
in every  jurisdiction in which the nature of the business conducted by it makes
such  qualification  necessary,  except to the extent  that the failure to be so
qualified or be in good standing would not have a Material  Adverse  Effect.  As
used in this Agreement,  "MATERIAL  ADVERSE  EFFECT" means any material  adverse
effect on the business,  properties,  assets, operations, results of operations,
financial  condition or prospects of the Company and its  subsidiaries,  if any,

or similar  provisions  that will be triggered by the issuance of the Securities
as described in this Agreement  except,  potentially,  under the warrants issued

Company has  furnished  to the Buyers true and correct  copies of the  Company's
Certificate  of  Incorporation,  as amended  and as in effect on the date hereof
(the "CERTIFICATE OF INCORPORATION"), and the Company's By-laws, as in effect on

thereof in respect thereto.

                  d.    ISSUANCE OF  SECURITIES.  The Preferred  Shares are duly

from all taxes,  liens and charges with respect to the issue  thereof,  with the
holders  being  entitled  to all rights  accorded  to a holder of Common  Stock.
Based, in part, upon the representations, warranties and covenants of the Buyers
contained  herein,  the issuance by the Company of the Preferred  Shares and the
Warrants,  is exempt  from  registration  under the 1933 Act and the  Conversion
Shares and the Warrant  Shares will be exempt from  registration  under the 1933
Act.

                  e.    NO CONFLICTS. The execution, delivery and performance of
the Transaction  Documents by the Company and the consummation by the Company of
the transactions contemplated hereby and thereby (including, without limitation,
the reservation for issuance and issuance of the Conversion Shares) will not (i)
result in a violation of the  Certificate of  Incorporation,  any Certificate of
Designations,  Preferences  and Rights of any  outstanding  series of  Preferred
Stock,  or the By-laws of the  Company,  (ii)  conflict  with,  or  constitute a
default (or an event  which with notice or lapse of time or both would  become a
default)  under,  or  give to  others  any  rights  of  termination,  amendment,
acceleration or cancellation of, any agreement, indenture or instrument to which
the Company or any of its subsidiaries is a party (except that the redemption of
the Preferred  Shares may violate (x) the Revolving  Credit Loan Agreement dated
January 31, 1995, as amended,  between TII International,  Inc., the Company and
The Chase  Manhattan Bank and (y) the Finance  Agreement  dated June 2, 1991, as
amended, between the Company and Overseas Private Investment Corporation and any
conversion  of  Preferred  Shares at an  exercise  price  below  $2.50 per share
(adjusted for stock  dividends,  stock splits and combinations and the like) may
violate said Finance Agreement) or (iii) result in a violation of any law, rule,
regulation,  order,  judgment or decree (including  federal and state securities
laws and regulations  and the rules and  regulations of the principal  market or
exchange on


                                       -7-

which the Common Stock is traded or listed)  applicable to the Company or any of
its  subsidiaries or by which any property or asset of the Company or any of its
subsidiaries  is bound or  affected,  except to the extent that  matters  within
clauses  (ii) and (iii)  immediately  above  would not have a  Material  Adverse
Effect.  Except as  disclosed  in  Schedule  3(e),  neither  the Company nor its
subsidiaries  is in  violation  of any  term  of or in  default  under  (i)  the
Certificate of Incorporation or the By-laws or their  organizational  charter or
by-laws, respectively, or (ii) any contract, agreement, mortgage,  indebtedness,
indenture,  instrument,  judgment,  decree  or  order  or any  statute,  rule or
regulation  applicable to the Company or its subsidiaries,  except to the extent
that such  violation or default would not have a Material  Adverse  Effect.  The
business of the Company and its subsidiaries is not being  conducted,  and shall
not  be  conducted,  in  violation  of any  law,  ordinance,  regulation  of any
governmental  entity,  except to the extent that such violation would not have a
Material Adverse Effect.  Except as specifically  contemplated by this Agreement
and as required under the 1933 Act and the 1934 Act, the Company is not required
to  obtain  any  consent,  authorization  or order  of,  or make any  filing  or
registration with, any court or governmental  agency in order for it to execute,
deliver  or  perform  any  of  its  obligations  under  or  contemplated  by the
Transaction  Documents or the Certificate of Designations in accordance with the
terms hereof or thereof.  Except as disclosed in Schedule  3(e),  all  consents,
authorizations,  orders, filings and registrations which the Company is required
to obtain  pursuant to the preceding  sentence have been obtained or effected on
or prior to the date hereof. The Company and its subsidiaries are unaware of any
facts or  circumstances  which  might  give  rise to any of the  foregoing.  The
Company is not in violation of the listing  requirements  of the Nasdaq National
Market and is not aware of any facts which would reasonably lead to delisting of
the Common Stock by the Nasdaq National Market in the foreseeable future.

                  f.    SEC  DOCUMENTS;  FINANCIAL  STATEMENTS.  Since  June 29,
1996, the Company has filed all reports,  schedules, forms, statements and other
documents  required  to be filed by it with the SEC  pursuant  to the  reporting
requirements  of the  1934  Act (all of the  foregoing  filed  prior to the date
hereof and all exhibits included therein and financial  statements and schedules
thereto and  documents  incorporated  by  reference  therein  being  hereinafter
referred to as the "SEC  DOCUMENTS").  The Company  has made  available  to each
Buyer or its  respective  representatives  true and  complete  copies of the SEC
Documents.  As of their  respective  dates,  the SEC  Documents  complied in all
material  respects  with the  requirements  of the 1934  Act and the  rules  and
regulations of the SEC promulgated  thereunder  applicable to the SEC Documents,
and  none of the SEC  Documents,  at the  time  they  were  filed  with the SEC,
contained any untrue statement of a material fact or omitted to state a 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.  As of their  respective  dates,  the  financial  statements  of the
Company  included  in the SEC  Documents  complied  as to  form in all  material
respects with  applicable  accounting  requirements  and the published rules and
regulations of the SEC with respect thereto. Such financial statements have been
prepared  in  accordance   with  generally   accepted   accounting   principles,
consistently  applied,  during  the  periods  involved  (except  (i)  as  may be
otherwise  indicated in such financial  statements or the notes thereto, or (ii)
in the case of  unaudited  interim  statements,  to the extent  they may exclude
footnotes or may be condensed or summary  statements)  and fairly present in all
material respects the financial  position of the Company as of the dates thereof
and the results of its operations and cash flows for the periods


                                       -8-

<PAGE>



then ended  (subject,  in the case of unaudited  statements,  to normal year-end
audit adjustments). No other information provided by or on behalf of the Company
to the Buyers which is not  included in the SEC  Documents,  including,  without
limitation,  information referred to in Section 2(d) of this Agreement, contains
any untrue  statement  of a material  fact or omits to state any  material  fact
necessary  in  order  to  make  the  statements  therein,  in the  light  of the
circumstance  under  which they are or were made,  not  misleading.  Neither the
Company  nor  any of its  subsidiaries  or any  of  their  officers,  directors,
employees  or agents  have  provided  the Buyers  with any  material,  nonpublic
information.

                  g.    ABSENCE  OF  CERTAIN  CHANGES.  Except as  disclosed  in
Schedule 3(g) or reflected or contemplated in any SEC Documents,  since June 27,
1997  there  has  been  no  material  adverse  change  and no  material  adverse
development  in the business,  properties,  operations,  financial  condition or
results of  operations of the Company or its  subsidiaries.  The Company has not
taken  any  steps,  and does not  currently  expect to take any  steps,  to seek
protection  pursuant  to any  bankruptcy  law nor does the Company or any of its
subsidiaries  have any knowledge or reason to believe that its creditors  intend
to initiate involuntary bankruptcy proceedings.

                  h.    ABSENCE  OF  LITIGATION.   There  is  no  action,  suit,
proceeding,  inquiry  or  investigation  before or by any court,  public  board,
government  agency,  self-regulatory  organization  or body  pending  or, to the
knowledge  of the  Company  or any of its  subsidiaries,  threatened  against or
affecting the Company, the Common Stock or any of the Company's  subsidiaries or
any of the  Company's or the  Company's  subsidiaries'  officers or directors in
their capacities as such, except as expressly set forth in Schedule 3(h).

                  i.    ACKNOWLEDGMENT  REGARDING  BUYERS' PURCHASE OF PREFERRED
SHARES.  The Company  acknowledges  and agrees that each of the Buyers is acting
solely in the capacity of arm's length purchaser with respect to the Transaction
Documents  and  the  transactions  contemplated  thereby.  The  Company  further
acknowledges  that each Buyer is not acting as a financial  advisor or fiduciary
of the Company  (or in any similar  capacity)  with  respect to the  Transaction
Documents and the transactions  contemplated thereby and any advice given by any
of the Buyers or any of their respective representatives or agents in connection
with the  Transaction  Documents and the  transactions  contemplated  thereby is
merely  incidental  to such  Buyer's  purchase  of the  Securities.  The Company
further  represents to each Buyer that the Company's  decision to enter into the
Transaction Documents has been based solely on the independent evaluation by the
Company and its representatives.

                  j.    NO  UNDISCLOSED  EVENTS,  LIABILITIES,  DEVELOPMENTS  OR
CIRCUMSTANCES.  No material event,  liability,  development or circumstance  has
occurred or exists,  with  respect to the Company or its  subsidiaries  or their
respective business, properties,  prospects,  operations or financial condition,
that  would  be  required  to be  disclosed  by  the  Company  under  applicable
securities laws on a registration  statement  (including by way of incorporation
by reference) filed with the SEC relating to an issuance and sale by the Company
of its Common Stock and which has not been publicly announced.

                  k.    NO  GENERAL  SOLICITATION.  Subject,  in  part,  to  the
accuracy of the Buyer's  representation  and warranty contained in Section 2(b),
neither the Company, nor any of its affiliates,  nor any person acting on its or
their  behalf,  has  engaged  in any form of  general  solicitation  or  general
advertising  (within  the  meaning  of  Regulation  D  under  the  1933  Act) in
connection with the offer or sale of the Securities.

                  l.    NO  INTEGRATED  OFFERING.   Subject,  in  part,  to  the
accuracy of the Buyer's representations and warranties, neither the Company, nor
any of its  affiliates,  nor any  person  acting  on its or  their  behalf  has,
directly or  indirectly,  made any offers or sales of any  security or solicited
any  offers  to  buy  any  security,  under  circumstances  that  would  require
registration of any of the Securities  under the 1933 Act or cause this offering
of Securities to be integrated  with prior offerings by the Company for purposes
of the 1933 Act or any applicable  stockholder approval  provisions,  including,
without  limitation,  under the rules and  regulations  of the  Nasdaq  National
Market, nor will the Company or any of its subsidiaries take any action or steps
that  would  require  registration  of the  Securities  under  the  1933 Act for
issuance hereunder or cause the offering of the Securities to be integrated with
other offerings.

                  m.    EMPLOYEE  RELATIONS.  Neither the Company nor any of its
subsidiaries is involved in any union labor dispute nor, to the knowledge of the
Company or any of its subsidiaries, is any such dispute threatened.  Neither the
Company  nor any of its  subsidiaries  is a  party  to a  collective  bargaining
agreement,  and the Company and its  subsidiaries  believe that  relations  with
their employees are good.

                  n.    INTELLECTUAL  PROPERTY  RIGHTS.  To the knowledge of the
Company,  the Company and its  subsidiaries  own or possess  adequate  rights or
licenses  to use all  trademarks,  trade  names,  service  marks,  service  mark
registrations,  service names, patents, patent rights,  copyrights,  inventions,
licenses,  approvals,  governmental  authorizations,  trade  secrets  and rights
necessary to conduct their respective businesses as now conducted, except to the
extent  that the failure to possess  such  rights or  licenses  would not have a
Material  Adverse  Effect,  and except further to the extent that the Company or
its  subsidiaries  lack  such  rights or  licenses,  they are using or shall use
commercially  reasonable efforts to secure such rights or licenses.  The Company
and its  subsidiaries  do not  have any  knowledge  of any  infringement  by the
Company or its  subsidiaries of trademark,  trade name rights,  patents,  patent
rights, copyrights,  inventions, licenses, service names, service marks, service
mark  registrations,  trade secret or other similar rights of others,  or of any
such development of similar or identical trade secrets or technical  information
by others and,  there is no claim,  action or  proceeding  being made or brought
against, or to the Company's knowledge, being threatened against, the Company or
its  subsidiaries  regarding  trademark,  trade name,  patents,  patent  rights,
invention,  copyright,  license,  service  names,  service  marks,  service mark
registrations,  trade  secret or other  infringement;  and the  Company  and its
subsidiaries are unaware of any facts or circumstances  which might give rise to
any of the foregoing,  except for such facts and  circumstances  which would not
have a Material Adverse Effect.

                  o.    ENVIRONMENTAL LAWS. The Company and its subsidiaries (i)
are in compliance with  applicable  foreign,  federal,  state and local laws and
regulations  relating  to  the  protection  of  human  health  and  safety,  the
environment  or  hazardous  or  toxic   substances  or  wastes,   pollutants  or
contaminants ("ENVIRONMENTAL LAWS"), (ii) have received all permits, licenses or
other approvals required of them under applicable  Environmental Laws to conduct
their  respective  businesses  and  (iii) are in  compliance  with all terms and
conditions of any such permit, license or approval,  except to the extent that a
failure with  respect to the matters  within  clauses (i),  (ii) and (iii) above
would not have a Material Adverse Effect.

                  p.    TITLE.  The Company and its  subsidiaries  have good and
marketable  title in fee  simple to all real  property  and good and  marketable
title to all  personal  property  owned by them,  except to the extent  that the
failure to have good and  marketable  title  would not have a  Material  Adverse
Effect,  in each case  free and clear of all  liens,  encumbrances  and  defects
except  such as are  described  in  Schedule  3(p) or such as do not  materially
affect the value of such  property  and do not  interfere  with the use made and
proposed to be made of such property by the Company or any of its  subsidiaries.
Except as discussed in the SEC Documents,  any real property and facilities held
under  lease by the  Company or any of its  subsidiaries  are held by them under
valid,  subsisting  and  enforceable  leases  with  such  exceptions  as are not
material and do not interfere  with the use made and proposed to be made of such
property and buildings by the Company and its subsidiaries.

                  q.    INSURANCE.  The Company and each of its subsidiaries are
insured by insurers of recognized financial  responsibility  against such losses
and risks and in such  amounts  as  management  of the  Company  believes  to be
prudent  and  customary  in  the   businesses  in  which  the  Company  and  its
subsidiaries  are engaged.  Neither the Company nor any of its  subsidiaries has
any reason to believe that it will not be able to renew its  existing  insurance
coverage as and when such coverage  expires or to obtain  similar  coverage from
similar  insurers as may be  necessary  to continue  its business at a cost that
would not materially and adversely affect the condition, financial or otherwise,
or the earnings,  business or  operations  of the Company and its  subsidiaries,
taken as a whole.

                  r.    REGULATORY  PERMITS.  The Company  and its  subsidiaries
possess all certificates,  authorizations  and permits issued by the appropriate
federal,  state or foreign  regulatory  authorities  necessary to conduct  their
respective  businesses,  except to the extent that the  failure to possess  such
certificates,  authorizations  and  permits  would not have a  Material  Adverse
Effect;  and neither the Company nor any such subsidiary has received any notice
of  proceedings   relating  to  the  revocation  or  modification  of  any  such
certificate, authorization or permit.

                  s.    INTERNAL  ACCOUNTING  CONTROLS.  The Company and each of
its subsidiaries maintain a system of internal accounting controls sufficient to
provide  reasonable  assurance that (i)  transactions are executed in accordance
with  management's  general or specific  authorizations,  (ii)  transactions are
recorded  as  necessary  to  permit  preparation  of  financial   statements  in
conformity with generally accepted  accounting  principles and to maintain asset
accountability,  (iii) access to assets is  permitted  only in  accordance  with
management's general or specific authorization and (iv) the


                                      -11-

<PAGE>



recorded  accountability  for assets is  compared  with the  existing  assets at
reasonable  intervals  and  appropriate  action  is taken  with  respect  to any
differences.

                  t.    NO  MATERIALLY  ADVERSE  CONTRACTS,   ETC.  Neither  the
Company nor any of its  subsidiaries  is subject to any  charter,  corporate  or
other legal  restriction,  or any judgment,  decree,  order,  rule or regulation
which in the judgment of the Company's officers has or is expected in the future
to have a Material Adverse Effect.

                  u.    TAX STATUS. The Company and each of its subsidiaries has
made or filed all federal and state  income and all other tax  returns,  reports
and declarations required by any jurisdiction to which it is subject (unless and
only to the extent that the Company and each of its  subsidiaries  has set aside
on its books  provisions  reasonably  adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental  assessments and
charges  that are  material  in  amount  shown or  determined  to be due on such
returns,  reports and declarations,  except those being contested in good faith,
and the Company  and its  subsidiaries  have set aside on their books  provision
reasonably  adequate for the payment of all taxes for periods  subsequent to the
periods  to which such  returns,  reports or  declarations  apply.  There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction,  and the officers of the Company know of no basis for any such
claim.

                  v.    DILUTIVE   EFFECT.    The   Company    understands   and
acknowledges  that the number of Conversion  Shares  issuable upon conversion of
the  Preferred  Shares  issuable  will  increase in certain  circumstances.  The
Company further acknowledges that its obligation to issue Conversion Shares upon
conversion of the Preferred  Shares in  accordance  with this  Agreement and the
Certificate  of  Designations  is absolute and  unconditional  regardless of the
dilutive effect that such issuance may have on the ownership  interests of other
stockholders of the Company.

                  w.    NO OTHER  AGREEMENTS.  The Company has not,  directly or
indirectly,  made  any  agreements  with any  Buyers  relating  to the  terms or
conditions of the transactions  contemplated by the Transaction Documents except
as set forth in the Transaction Documents.

            4.    COVENANTS.

                  a.    BEST  EFFORTS.  Each  party  shall use its best  efforts
timely to satisfy  each of the  conditions  to be satisfied by it as provided in
Sections 6 and 7 of this Agreement.

                  b.    FORM D. The Company agrees to file a Form D with respect
to the Securities as required  under  Regulation D and to provide a copy thereof
to each Buyer promptly after such filing.  The Company shall,  on or before each
of the Closing Dates, take such action as the Company shall reasonably determine
is  necessary  to  qualify  the  Securities  for,  or obtain  exemption  for the
Securities  for,  sale to the Buyers at each of the  Closings  pursuant  to this
Agreement  under  applicable  securities or "Blue Sky" laws of the states of the
United  States,  and shall  provide  evidence of any such action so taken to the
Buyers on or prior to the Closing Date.

                  c.    REPORTING  STATUS.  Until the earlier of (i) the date as
of which the  Investors  (as that term is  defined  in the  Registration  Rights
Agreement)  may sell all of the  Conversion  Shares and Warrant  Shares  without
restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto),  or (ii) the date on which (A) the  Investors  shall have sold all the
Conversion  Shares and Warrant  Shares and (B) none of the Preferred  Shares and
Warrants are outstanding (the "REGISTRATION PERIOD"), the Company shall file all
reports  required  to be filed with the SEC  pursuant  to the 1934 Act,  and the
Company  shall not  terminate  its status as an issuer  required to file reports
under the 1934 Act even if the 1934 Act or the rules and regulations  thereunder
would otherwise permit such termination.

                  d.    USE OF PROCEEDS.  The Company will use the proceeds from

Quarterly  Reports  on Form  10-Q,  any  Current  Reports  on  Form  8-K and any
registration  statements or amendments  filed  pursuant to the 1933 Act; (ii) on
the same day as the  release  thereof,  facsimile  copies of all press  releases
issued by the Company or any of its subsidiaries and (iii) copies of any notices

                  f.    RESERVATION OF SHARES. The Company shall take all action
necessary  to at all times have  authorized,  and  reserved  for the  purpose of

                  g.    RIGHT OF FIRST REFUSAL. So long as at least an aggregate
of 10% of the Preferred  Shares issued at the Closings remain  outstanding,  but
subject to the exceptions  described  below,  the Company shall not enter into a
binding  agreement  or otherwise  agree with any party for any equity  financing
(including  any debt  financing  with an equity  component)  or issue any equity
securities of the Company or securities  convertible or exchangeable into or for
equity  securities  of the Company  (including  debt  securities  with an equity
component) in any form ("FUTURE  OFFERINGS")  during the period beginning on the
Closing  Date and ending on and  including  the date which is 365 days after the
Closing Date,  unless it shall have first  delivered to each Buyer or a designee
appointed by such Buyer written notice (the "FUTURE OFFERING NOTICE") describing
the proposed Future Offering,  including the terms and conditions  thereof,  and
providing  each Buyer an option to purchase up to its Aggregate  Percentage  (as
defined below), as of the date of delivery of the Future Offering Notice, in the
Future  Offering  on the same  terms  and  conditions  set  forth in the  Future

4(g), "AGGREGATE


                                      -13-

<PAGE>



PERCENTAGE"  at any time with  respect to any Buyer  shall  mean the  percentage
obtained by dividing (i) the  aggregate  number of  Conversion  Shares issued or
issuable,  as if a  conversion  occurred on such date,  upon  conversion  of the
Preferred Shares held by such Buyer (without giving effect to the limitations on
conversion  contained  herein or in the Certificate of Designations) by (ii) the
aggregate  number of Conversion  Shares  issued or issuable,  as if a conversion
occurred on such date,  upon  conversion of all of the Preferred  Shares held by
the Buyers.  A Buyer can exercise its option to participate in a Future Offering
by delivering  written  notice  thereof to participate to the Company within ten
(10) business days of receipt of a Future  Offering  Notice,  which notice shall
state the quantity of securities  being offered in the Future Offering that such
Buyer  will  purchase,  up to its  Aggregate  Percentage,  and  that  number  of
securities it is willing to purchase in excess of its Aggregate  Percentage.  In
the event  that one or more  Buyers  fail to elect to  purchase  up to each such
Buyer's  Aggregate  Percentage  then each Buyer which has  indicated  that it is
willing to purchase a number of securities in excess of its Aggregate Percentage
shall be  entitled  to  purchase  its pro rata  portion  (based on the number of
securities  which each Buyer  electing  to  purchase  securities  has elected to
purchase) of the securities in the Future Offering which one or more Buyers have
not  elected  to  purchase.  In the  event  the  Buyers  fail to  elect to fully
participate in the Future Offering within the periods  described in this Section
4(g),  the Company shall have 45 days  thereafter to sell the  securities of the
Future Offering  respecting  which such Buyer's rights were not exercised,  upon
terms and conditions, no more favorable to the purchasers thereof than specified
in the  Future  Offering  Notice.  In the  event the  Company  has not sold such
securities of the Future Offering  within such 45 day period,  the Company shall
not  thereafter  issue or sell  such  securities  without  first  offering  such
securities  to the Buyers in the  manner  provided  in this  Section  4(g).  The
Capital Raising Limitation shall not apply to (i) a loan from a commercial bank,
(ii) any  transaction  involving  the Company's  issuances of securities  (A) as
consideration in a merger or consolidation, (B) in connection with any strategic
partnership  or joint  venture  (the  primary  purpose  of which is not to raise
equity  capital),  or (C) as  consideration  for the  acquisition of a business,
product or license by the  Company,  (iii) the  issuance  of Common  Stock in an
underwritten  public offering,  (iv) the issuance of securities upon exercise or
conversion of the Company's  options,  warrants or other convertible  securities
outstanding  as of the date hereof,  and (v) the grant of additional  options or
warrants,  or the issuance of  additional  securities,  under any Company  stock
option or  restricted  stock plan for the  benefit of the  Company's  employees,
directors or  consultants.  The Buyers shall not be required to  participate  or
exercise  their  right of first  refusal  with  respect to a  particular  Future
Offering in order to exercise their right of first refusal with respect to later
Future Offerings.

                  h.    LISTING.  The Company shall promptly  secure the listing
of all of the  Registrable  Securities  (as defined in the  Registration  Rights
Agreement) upon the Nasdaq National  Market,  The New York Stock Exchange,  Inc.
("NYSE") or The American Stock  Exchange,  Inc.  ("AMEX"),  upon which shares of
Common Stock are then listed  (subject to official notice of issuance) and shall
maintain,  so long as any other shares of Common Stock shall be so listed,  such
listing of all Registrable Securities from time to time issuable under the terms
of the Transaction Documents. The Company shall use its best efforts to maintain
the Common Stock's  authorization  for quotation on the Nasdaq National  Market,
NYSE or AMEX (but shall not be responsible for deficiencies caused by changes in
the market  price of its Common  Stock,  the effects of  operational  results or
changes in


                                      -14-

<PAGE>



the  listing  and  qualification  maintenance  standards  adopted by any of such
self-regulatory organizations).  Neither the Company nor any of its subsidiaries
shall  take  any  intentional  action  which  may  result  in the  delisting  or
suspension of the Common Stock on the Nasdaq National Market,  NYSE or AMEX. The
Company shall  promptly  provide to each Buyer copies of any notices it receives
from  the  Nasdaq  National  Market,   NYSE  or  AMEX  regarding  the  continued
eligibility of the Common Stock for listing on such automated  quotation  system
or  securities  exchange.  The  Company  shall  pay all  fees  and  expenses  in
connection with satisfying its obligations under this Section 4(h).

                  i.    SHORT  SALES.  Buyers  agree not to enter into any short
position  involving  the  Common  Stock  (including  by selling  put  equivalent
positions, as that term has meaning under the rules promulgated by the SEC under
Section  16(a) of the 1934 Act),  at a sales price per share of Common  Stock of
less than $4.45 until, and including, 120 days after the Closing.

                  j.    FILING OF FORM 8-K.  On or before  the tenth  (10th) day
following each of the Closing Dates,  the Company shall file a Form 8-K with the
SEC  describing the terms of the  transaction  contemplated  by the  Transaction
Documents and consummated at such Closing,  in each case in the form required by
the 1934 Act and including a copy of Certificate of Designation as an exhibit to
such report.  Neither such Report nor any other report filed by the Company with
the SEC shall  include  the name of any Buyer nor file a copy of this  unless in
response to a comment received from the SEC.

                  k.    UNDERWRITING LOCK-UP AGREEMENTS.  At any time during the
period  beginning on and including the Closing Date and ending on the date which
is four years after the Closing Date,  the Company may require that all, but not
less than all, of the holders of the Preferred Shares and Warrants agree to sign
a "lock-up"  agreement with the  underwriters of a public offering of the Common
Stock  pursuant  to which the  holders  would  agree not to sell any  Conversion
Shares or Warrant Shares during the period  beginning on the date  designated by
the  underwriters,  which date shall be not less than 10 days after the holders'
receipt  of  such  notice  (no  longer  than 10 days  prior  to the  anticipated
effective date of the registration  statement for such offering),  and ending on
the date  which is not  longer  than (i) the  number  of days  during  which the
Company's principal officers have agreed to similar restrictions or (ii) 60 days
after the beginning of the lock-up period as designated by the underwriters (the
"UNDERWRITING  LOCK-UP  PERIOD").  The  Company  shall  exercise  this  right by
delivering  written notice (the "LOCK-UP REQUEST NOTICE") of such request to all
of the holders of the Preferred Shares and Warrants then outstanding at least 10
days prior to the date on which the Underwriting  Lock-Up Period will begin, but
in no event prior to the initial filing of the  registration  statement for such
proposed  offering.  The  Lock-up  Request  Notice  shall  state  (i)  that  the
underwriters  of such offering have  requested that the holders of the Preferred
Shares and Warrants enter into "lock-up" agreements,  (ii) the date on which the
Underwriting  Lock-Up  Period  will  begin and  (iii)  the name of the  managing
underwriters  of the  proposed  offering.  Notwithstanding  the  foregoing,  the
Company  shall not be  entitled  to require  the  holders to enter into  lock-up
agreements  unless (A) the Underwriting  Lock-Up Period is not more than 60 days
or such lesser number of days during which the Company's principal officers have
agreed to similar


                                      -15-

<PAGE>



restrictions,  (B) the Underwriting  Lock-Up Period shall terminate  immediately
upon the  termination  or abandonment  or indefinite  delay of the  underwritten
offering,  (C) the managing underwriters for such proposed offering are included
on the Schedule of Underwriters attached to this Agreement,  (D) the preliminary
prospectus for such  underwritten  public offering reflects a price per share to
the public of not less than $7.50 per share (to be adjusted for stock dividends,
splits,  combinations and similar events) and an aggregate gross proceeds to the
Company  of at least  $10,000,000,  (E)  there  has  been no other  Underwriting
Lock-Up Period in the 365 days prior to the date of the Lock-Up  Request Notice,
and (F) there has been no Grace  Period (as defined in the  Registration  Rights
Agreement)  during the period  beginning on and  including the date which is ten
days prior to the initial filing of the registration  statement for the proposed
offering and ending on and including the first day of the  Underwriting  Lock-Up
Period.  In the event the Company requires an Underwriting  Lock-Up Period,  the
Mandatory  Conversion Date (as defined in the Certificate of Designations) shall
be delayed two days for each day in the Underwriting  Lock-Up Period as provided
in Section 2(g) of the Certificate of  Designations.  If the Company  delivers a
Lock-Up Request Notice and the  underwritten  public offering is not consummated
within 90 days of the first day of the  Underwriting  Lock-Up  Period,  then the
Company may require an Underwriting Lock-Up Period pursuant to this Section 4(k)
on only one other occasion.

                  l.    LISTING  OF SHARES ON  NASDAQ.  Promptly  following  the
Closing, but no later than ten (10) days thereafter,  the Company shall file all
necessary applications and documents so that all of the Conversion Shares (up to
the Exchange  Cap) and the  Warrants  Shares  issuable  upon  conversion  of the
Preferred  Shares  to be sold at the  Closing  shall be listed  upon the  Nasdaq
National Market.

                  m.    ADDITIONAL  GOOD STANDING  CERTIFICATES.  If the Company
has not obtained good standing certificates for TII-Ditel, Inc. and Crown Tool &
Die,  Inc. on or prior to the Closing  Date  pursuant to Section  7(a)(x),  then
promptly following the Closing, but no later than ten (10) days thereafter,  the
Company  shall provide to the Buyers an updated good  standing  certificate  for
TII-Ditel, Inc. and a good standing certificate for Crown Tool & Die, Inc.

            5.    TRANSFER AGENT INSTRUCTIONS.

                  The  Company  shall  issue  irrevocable  instructions  to  its
transfer  agent,  and any  subsequent  transfer  agent,  to issue  certificates,
registered  in the name of each  Buyer  or its  respective  nominee(s),  for the
Conversion  Shares in such amounts as specified  from time to time by each Buyer
to the  Company  upon  conversion  of the  Preferred  Shares  (the  "IRREVOCABLE
TRANSFER AGENT INSTRUCTIONS"),  subject to the maximum number of shares provided
for in  Sections  2(j)  and 12 of  the  Certificate  of  Designation.  Prior  to
registration of the Conversion  Shares under the 1933 Act, all such certificates
shall bear the restrictive  legend  specified in Section 2(g) of this Agreement.
The Company  warrants that no instruction  other than the  Irrevocable  Transfer
Agent Instructions referred to in this Section 5, and stop transfer instructions
to give  effect to Section  2(f) hereof (in the case of the  Conversion  Shares,
prior to registration of the Conversion Shares under the 1933 Act) or Sections 4
or 12 of the Certificate of Designation will be given by the Company to its


                                      -16-

<PAGE>



transfer agent and that the Securities shall otherwise be freely transferable on
the books and  records  of the  Company as and to the  extent  provided  in this
Agreement and the Registration Rights Agreement. Nothing in this Section 5 shall
affect in any way each Buyer's  obligations  and agreements set forth in Section
2(g) to comply with all applicable  prospectus  delivery  requirements,  if any,
upon resale of the  Securities.  If a Buyer provides the Company with an opinion
of counsel,  reasonably  satisfactory in form and substance to the Company, that
registration of a resale by such Buyer of any of such Securities is not required
under the 1933 Act, the Company shall permit the  transfer,  and, in the case of
the Conversion Shares, promptly instruct its transfer agent to issue one or more
certificates in such name and in such  denominations  as specified by such Buyer
and without any restrictive  legends.  The Company acknowledges that a breach by
it of its  obligations  hereunder will cause  irreparable  harm to the Buyers by
vitiating  the  intent  and  purpose  of the  transaction  contemplated  hereby.
Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations  under this Section 5 will be inadequate and agrees, in the event of
a breach or threatened  breach by the Company of the  provisions of this Section
5, that the  Buyers  shall be  entitled,  in  addition  to all  other  available
remedies,  to an  injunction  restraining  any  breach and  requiring  immediate
issuance  and  transfer,  without the  necessity  of showing  economic  loss and
without any bond or other security being required.

                  a.    CLOSING DATE. The obligation of the Company hereunder to

then  outstanding,  and no  provision  hereof  may be  waived  other  than by an
instrument in writing signed by the party against whom enforcement is sought. No
such amendment shall be effective to the extent that it applies to less than all
of the holders of the Preferred Shares then outstanding.

            If to a Buyer,  to its address and facsimile  number on the Schedule
of  Buyers,  with  copies to such  Buyer's  representatives  as set forth on the
Schedule of Buyers.

            Each party shall provide five (5) days' prior written  notice to the
other party of any change in address or facsimile number.

                  g.    SUCCESSORS AND ASSIGNS.  This Agreement shall be binding
upon and inure to the benefit of the parties and their respective successors and
assigns, including any purchasers of the Preferred Shares. The Company shall not
assign this Agreement or any rights or obligations  hereunder  without the prior
written consent of the holders of two-thirds  (2/3) of the Preferred Shares then
outstanding,  except pursuant to a Major Transaction (as defined in Section 3(c)
of  the  Certificate  of  Designations)  in  compliance  with  Section  3 of the
Certificate  of  Designations.  A Buyer  may  assign  some or all of its  rights
hereunder to affiliates or associates of such Buyer,  without the consent of the
Company, and to others, with the consent of the Company; provided, however, that
(i) any such  assignment  shall not  release  such  Buyer  from its  obligations
hereunder  unless such  obligations are assumed by such assignee and the Company
has consented to such assignment and assumption and (ii) the assignee executes a
copy of this  Agreement and makes each of the  representations,  warranties  and
covenants of its assignor contained herein, and agrees to be bound by all of the
provisions of the Transaction Documents and the Certificate of Designation.

                  h.    NO THIRD PARTY BENEFICIARIES. This Agreement is intended
for the benefit of the parties hereto and their respective  permitted successors
and  assigns,  and is not for the  benefit of, nor may any  provision  hereof be
enforced by, any other person.

                  i.    SURVIVAL.  Unless this  Agreement  is  terminated  under
Section 9(l), the  representations  and warranties of the Company and the Buyers
contained  in  Sections  2 and 3, the  agreements  and  covenants  set  forth in
Sections 4, 5 and 9, and the indemnification  provisions set forth in Section 8,
shall survive each of the Closing.  Each Buyer shall be responsible only for its
own representations, warranties, agreements and covenants hereunder.

                  j.    PUBLICITY.  The Company and one representative  selected
by the Buyers shall have the right to approve before issuance any press releases
or any other public  statements  with respect to the  transactions  contemplated
hereby; provided, however, that the Company shall be entitled, without the prior
approval of any Buyer,  to issue the press release in the form annexed hereto as
Exhibit G and make any press release or other public  disclosure with respect to
such  transactions  as is required by applicable law and  regulations  (although
each Buyer shall be consulted by the


                                      -22-

<PAGE>



Company in  connection  with any such press  release or other public  disclosure
prior to its release and shall be provided with a copy thereof).

                  k.    FURTHER ASSURANCES.  Each party shall do and perform, or
cause to be done and  performed,  all such  further  acts and things,  and shall
execute and deliver all such other  agreements,  certificates,  instruments  and
documents,  as the other party may reasonably  request in order to carry out the
intent and accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

                  l.    TERMINATION.  In the event  that the  Closing  shall not
have occurred with respect to any Buyer on or before four (4) business days from
the date  hereof due to the  Company's  or such  Buyer's  failure to satisfy the
conditions  set forth in  Sections 6 and 7 above (and the  nonbreaching  party's
failure to waive such unsatisfied  condition(s)),  the nonbreaching  party shall
have the option to terminate this Agreement with respect to such breaching party
at the close of  business  on such date  without  liability  of any party to any
other party; provided, however, that if this Agreement is terminated pursuant to
this  Section  9(l),  the  Company  shall  remain  obligated  to  reimburse  the
non-breaching Buyers for the expenses described in Section 4(i) above.

                  m.    PLACEMENT  AGENT. The Company  acknowledges  that it has
engaged Jesup & Lamont  Securities  Corp. as placement  agent in connection with
the sale of the Preferred Shares.

                  n.    NO  STRICT  CONSTRUCTION.  The  language  used  in  this
Agreement  will be deemed to be the  language  chosen by the  parties to express
their mutual intent, and no rules of strict construction will be applied against
any party.

                  o.    EXPENSES. Each party will bear its own expenses incurred
in the preparation and closing of the Transaction Documents and in reviewing the
Registration Statement provided for in the Registration Rights Agreement.

                  p.    COUNTERPARTS.  This  Agreement may be executed in two or
more identical  counterparts,  each of which shall be deemed an original but all
of which shall  constitute  one and the same  agreement.  This  Agreement,  once
executed by a party,  may be  delivered  to the other party  hereto by facsimile
transmission  of a copy of this Agreement  bearing the signature of the party so
delivering this Agreement.

                          REGISTRATION RIGHTS AGREEMENT


            REGISTRATION  RIGHTS  AGREEMENT  (this  "AGREEMENT"),  dated  as  of

            WHEREAS:

            A.    In connection  with the Securities  Purchase  Agreement by and
among the parties of even date herewith (the "SECURITIES  PURCHASE  AGREEMENT"),
the  Company has agreed,  upon the terms and  subject to the  conditions  of the
Securities Purchase Agreement, to issue and sell to the Buyers (a) shares of the

"CONVERSION  SHARES"), in accordance with the terms of the Company's Certificate
of Designation of the Series C Convertible  Preferred Stock (the "CERTIFICATE OF
DESIGNATION");  and (b) Warrants (the  "WARRANTS") to purchase  shares of Common
Stock (as exercised, the "WARRANT SHARES");

            B.    To induce the Buyers to execute  and  deliver  the  Securities
Purchase  Agreement,  the  Company  has agreed to provide  certain  registration
rights  under  the  Securities  Act of  1933,  as  amended,  and the  rules  and
regulations  thereunder,  or any similar  successor statute  (collectively,  the
"1933 ACT"), and applicable state securities laws:

            NOW,  THEREFORE,  in  consideration  of the  premises and the mutual
covenants  contained  herein  and other  good and  valuable  consideration,  the
receipt and  sufficiency of which are hereby  acknowledged,  the Company and the

                        thereof to whom a Buyer  assigns  its rights  under this
                        Agreement   and  who  agrees  to  become  bound  by  the
                        provisions of this Agreement in accordance  with Section

                        subdivision thereof or a governmental agency.




<PAGE>



                  c.    "REGISTER,"  "REGISTERED," and "REGISTRATION" refer to a
                        registration  effected  by  preparing  and filing one or
                        more Registration Statements in compliance with the 1933
                        Act and  pursuant  to Rule 415 under the 1933 Act or any
                        successor  rule  providing for offering  securities on a
                        continuous  basis ("RULE 415"),  and the  declaration or
                        ordering   of   effectiveness   of   such   Registration
                        Statement(s)   by  the  United  States   Securities  and
                        Exchange Commission (the "SEC").

                  d.    "REGISTRABLE  SECURITIES"  means the  Conversion  Shares
                        issued or  issuable  upon  conversion  of the  Preferred
                        Shares and the Warrant  Shares  issued or issuable  upon
                        conversion  of the  Warrants  and any  shares of capital
                        stock issued or issuable with respect to the  Conversion
                        Shares,  the Preferred Shares, the Warrant Shares or the
                        Warrants as a result of any stock split, stock dividend,
                        recapitalization,   exchange   or   similar   event   or
                        otherwise.  Conversion  Shares or Warrant  Shares  shall
                        cease to be  Registrable  Securities  on the  earlier to
                        occur  of  (i)  when  sold  pursuant  to a  Registration
                        Statement   or  (ii)  when  they  may  be  sold  without
                        registration  pursuant  to  paragraph  (k) of  Rule  144
                        promulgated  under  the  1933  Act  (as  defined  in the
                        Certificate  of  Designation)   thereof,   whichever  is
                        earlier.

                  e.    "REGISTRATION  STATEMENT" means a registration statement
                        of the Company filed under the 1933 Act.

                  Capitalized terms used herein and not otherwise defined herein
shall  have  the  respective  meanings  set  forth  in the  Securities  Purchase
Agreement.

            2.    REGISTRATION.

                  a.    MANDATORY REGISTRATION.  The Company shall prepare, and,
on or prior to 60 days after the date of first  issuance  of  Preferred  Shares,
file with the SEC a  Registration  Statement or  Registration  Statements (as is
necessary) on Form S-3 (or, if such form is unavailable for such a registration,
on such  other  form as is  available  for such a  registration,  subject to the
consent of the Investors  holding a majority of the  Registrable  Securities and
the  provisions  of  Section  2(c),  which  consent  will  not  be  unreasonably
withheld),  covering  the  resale of all of the  Registrable  Securities,  which
Registration  Statement(s)  shall  state  that,  in  accordance  with  Rule  416
promulgated under the 1933 Act, such Registration  Statement(s) also covers such
undeterminate number of additional shares of Common Stock as may become issuable
upon conversion of the Preferred Shares to prevent dilution resulting from stock
splits,  stock dividends or similar  transactions.  Such Registration  Statement
shall initially  register for resale at least 2,280,000  shares of Common Stock,
subject to  adjustment as provided in Section 3(b).  Such  registered  shares of
Common Stock shall be allocated  among the Investors pro rata based on the total
number of  Registrable  Securities  issued or issuable  upon  conversion  of the
Preferred  Shares as of each date that a  Registration  Statement,  as  amended,
relating to the resale of the  Registrable  Securities is declared  effective by
the SEC. The Company



                                       -2-

<PAGE>



shall  use its best  efforts  to have  the  Registration  Statement(s)  declared
effective by the SEC as soon as practicable, but in no event later than 120 days
after the issuance of the relevant Preferred Shares.

                  b.    COUNSEL  AND  INVESTMENT  BANKERS.  Subject to Section 5
hereof,  in  connection  with any offering  pursuant to Section 2, the Investors
shall have the right to select one legal  counsel  and an  investment  banker or
bankers and manager or managers to  administer  their  interest in the offering,
which  investment  banker or bankers or manager or managers  shall be reasonably
satisfactory  to the Company.  The Company shall  reasonably  cooperate with any
such  counsel and  investment  bankers.  The  expenses,  including  underwriting
discounts and commissions,  fees and  disbursements of such counsel in excess of
$2,000,  and reasonable fees and  disbursements  of investment  bankers shall be
paid by the Buyers.

                  c.    PIGGY-BACK REGISTRATIONS. If a Registration Statement in
compliance with this Agreement is not effective,  and prior to the expiration of
the Registration Period (as hereinafter  defined),  the Company proposes to file
with  the SEC a  Registration  Statement  relating  to an  offering  for its own
account  or the  account of others  under the 1933 Act of any of its  securities
(other  than on Form S-4 or Form  S-8 or  their  then  equivalents  relating  to
securities to be issued solely in connection  with any acquisition of any entity
or business or equity  securities  issuable in  connection  with stock option or
other employee benefit plans),  the Company shall promptly send to each Investor
who is entitled to registration rights under this Section 2(c) written notice of
the Company's intention to file a Registration  Statement and of such Investor's
rights under this Section 2(c) and, if within  twenty (20) days after receipt of
such  notice,  such  Investor  shall so request in writing,  the  Company  shall
include  in such  Registration  Statement  all or any  part  of the  Registrable
Securities  such Investor  requests to be registered,  subject to the priorities
set  forth in  Section  2(d)  below.  No right to  registration  of  Registrable
Securities  under this Section 2(c) shall be construed to limit any registration
required under Section 2(a).  The  obligations of the Company under this Section
2(c)  may  be  waived  by  Investors  holding  a  majority  of  the  Registrable
Securities.  If an offering in connection  with which an Investor is entitled to
registration  under this Section  2(c) is an  underwritten  offering,  then each
Investor  whose  Registrable   Securities  are  included  in  such  Registration
Statement shall,  unless  otherwise  agreed by the Company,  offer and sell such
Registrable  Securities in such underwritten offering using the same underwriter
or underwriters  and,  subject to the provisions of this Agreement,  on the same
terms  and  conditions  as  other  shares  of  Common  Stock  included  in  such
underwritten offering.

                  d.    PRIORITY IN PIGGY-BACK REGISTRATION RIGHTS IN CONNECTION
WITH  REGISTRATIONS  FOR COMPANY  ACCOUNT.  If the  registration  referred to in
Section  2(c)  is  to  be an  underwritten  public  offering  and  the  managing
underwriter(s)  advise the Company in  writing,  that in their  reasonable  good
faith  opinion,  marketing or other  factors  dictate  that a limitation  on the
number of  shares of Common  Stock  which may be  included  in the  Registration
Statement (which may include a total  "cut-back" of all Registrable  Securities)
is necessary to  facilitate  and not  materially  adversely  affect the proposed
offering,  then the Company shall include in such  registration:  (1) first, all
securities the Company proposes to sell for its own account,  (2) second,  up to
the full number of securities  proposed to be registered  for the account of the
holders of securities entitled to inclusion of their securities in the


                                       -3-

<PAGE>



Registration  Statement by reason of demand registration  rights, and (3) third,
the securities requested to be registered by the Investors (which may not exceed
the maximum number of Conversion Shares they are then entitled to sell under the
Certificate  of  Designation)  and  other  holders  of  securities  entitled  to
participate in the registration, as of the date hereof, drawn from them pro rata
based on the number each has requested to be included in such registration.

                  e.    ELIGIBILITY  FOR FORM S-3.  The Company  represents  and
warrants  that,  to the best of its  knowledge,  on and after the date hereof it
meets the  requirements  for the use of Form S-3 for registration of the sale by
the  Investors  of the  Registrable  Securities  and the  Company  has filed all
reports  required to be filed by the Company with the SEC in a timely  manner so
as to obtain such eligibility for the use of Form S-3. The Company shall use its
best efforts to meet the  requirements  for use of Form S-3 for  registration of
the sale by the Investors of the  Registrable  Securities  and the Company shall
file all reports  required  to be filed by the Company  with the SEC in a timely
manner so as to maintain  eligibility for the use of Form S-3. In the event that
Form  S-3  is  not  available  for  sale  by the  Investors  of the  Registrable
Securities,  then the Company (i) with the  consent of the  Investors  holding a
majority of the Registrable  Securities  pursuant to Section 2(a), which consent
shall not be unreasonably  withheld,  shall register the sale of the Registrable
Securities on another  appropriate  form and (ii) the Company shall undertake to
register the  Registrable  Securities on Form S-3 (or convert such other form to
Form S-3) as soon as such form is  available,  provided  that the Company  shall
maintain the  effectiveness of the  Registration  Statement then in effect until
such time as a  Registration  Statement  on Form S-3  covering  the  Registrable
Securities has been declared effective by the SEC.

            3.    RELATED OBLIGATIONS.

                  Whenever  an  Investor  has  requested  that  any  Registrable
Securities be registered pursuant to Section 2(c) or at such time as the Company
is obligated to file a  Registration  Statement with the SEC pursuant to Section
2(a),  the Company will use its best efforts to effect the  registration  of the
Registrable  Securities in accordance  with the intended  method of  disposition
thereof and, pursuant thereto, the Company shall have the following obligations:

                  a.    The Company shall promptly prepare and file with the SEC
a Registration Statement with respect to the Registrable Securities (on or prior
to the thirtieth  (30th) day after the date of issuance of any Preferred  Shares
for the registration of Registrable Securities pursuant to Section 2(a)) and use
its  best  efforts  to  cause  such  Registration   Statement  relating  to  the
Registrable Securities to become effective as soon as possible after such filing
(but in no event  later  than 120  days  after  the  issuance  of any  Preferred
Shares), and keep such Registration  Statement effective pursuant to Rule 415 at
all times until the earlier of (i) the date as of which the  Investors  may sell
all of the Registrable  Securities without  restriction  pursuant to Rule 144(k)
promulgated under the 1933 Act (or successor  thereto) or (ii) the date on which
(A) the Investors shall have sold all the Registrable Securities and (B) none of
the  Preferred  Shares  is  outstanding  (the  "REGISTRATION   PERIOD"),   which
Registration  Statement  (including any  amendments or  supplements  thereto and
prospectuses  contained  therein)  shall not contain any untrue  statement  of a
material fact or omit to state a material


                                       -4-

<PAGE>



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; provided,
however,  that the Company  shall not be  responsible  for untrue  statements or
omissions  which  are  contained  therein  based  upon  and in  conformity  with
information  furnished  in writing to the Company by an Investor and used in the
Registration Statement.

                  b.    Subject to Section  3(f),  the Company shall prepare and
file with the SEC such  amendments  (including  post-effective  amendments)  and
supplements  to a Registration  Statement and the prospectus  used in connection
with such  Registration  Statement,  which prospectus is to be filed pursuant to
Rule 424  promulgated  under  the 1933  Act,  as may be  necessary  to keep such
Registration  Statement  effective at all times during the Registration  Period,
and, during such period, comply with the provisions of the 1933 Act with respect
to the disposition of all Registrable  Securities of the Company covered by such
Registration  Statement.  In the event the  number of shares  available  under a
Registration Statement filed pursuant to this Agreement is insufficient to cover
all of the  Registrable  Securities,  the Company shall file a new  Registration
Statement (on the short form available therefor, if applicable),  so as to cover
all of the Registrable Securities, in each case, as soon as practicable,  but in
any event within fifteen (15) days after the necessity therefor arises (based on
the market  price of the Common  Stock and other  relevant  factors on which the
Company  reasonably  elects to rely).  The Company shall use its best efforts to
cause such amendment  and/or new  Registration  Statement to become effective as
soon as practicable  following the filing thereof. For purposes of the foregoing
provision,  the number of shares available under a Registration  Statement shall
be deemed  "insufficient  to cover all of the Registrable  Securities" if at any
time the number of Registrable  Securities issued or issuable upon conversion of
the Preferred Shares is equal to the lesser of the then Exchange Cap (as defined
in the Certificate of  Designation)  or the quotient  determined by dividing (i)
the  number  of  shares  of  Common  Stock   available  for  resale  under  such
Registration Statement by (ii) 1.5. For purposes of the calculation set forth in
the foregoing sentence,  any restrictions on the convertibility of the Preferred
Shares shall be disregarded and such calculation shall assume that the Preferred
Shares are then  convertible  into shares of Common Stock at the then prevailing
Conversion Rate (as defined in the Certificate of  Designations);  provided that
the Company need not file a new Registration Statement covering less than 25,000
shares of Common  Stock;  provided  further  that if there are less than  25,000
shares of Common Stock  available as Registrable  Securities,  the Company shall
file a new Registration Statement covering such number of shares.

                  c.    The  Company  shall  furnish  to  each  Investor   whose
Registrable  Securities are included in any Registration Statement and its legal
counsel  without  charge (i) promptly  after the same is prepared and filed with
the SEC at least one copy of such  Registration  Statement and any  amendment(s)
thereto,   including   financial   statements  and   schedules,   all  documents
incorporated  therein by reference and all exhibits,  the prospectus included in
such Registration  Statement  (including each preliminary  prospectus) and, with
regards to such Registration Statement(s), any correspondence by or on behalf of
the Company to the SEC or the staff of the SEC and any  correspondence  from the
SEC or the staff of the SEC to the Company or its representatives, (ii) upon the
effectiveness of any Registration  Statement,  ten (10) copies of the prospectus
included in such Registration  Statement (or filed under Rule 424 under the 1933
Act) and all amendments and


                                       -5-

<PAGE>



supplements  thereto  (or such  other  number  of copies  as such  Investor  may
reasonably  request) and (iii) such other  documents,  including any preliminary
prospectus,  as such Investor may reasonably  request in order to facilitate the
disposition of the Registrable Securities owned by such Investor.

                  d.    The Company shall use reasonable efforts to (i) register
and qualify the Registrable Securities covered by a Registration Statement under
such other  securities  or "blue sky" laws of such  jurisdictions  in the United
States as any  Investor  reasonably  requests,  (ii)  prepare  and file in those
jurisdictions,   such  amendments  (including  post-effective   amendments)  and
supplements  to such  registrations  and  qualifications  as may be necessary to
maintain the effectiveness  thereof during the Registration  Period,  (iii) take
such other  actions as may be  necessary  to  maintain  such  registrations  and
qualifications in effect at all times during the Registration  Period,  and (iv)
take all  other  actions  reasonably  necessary  or  advisable  to  qualify  the
Registrable Securities for sale in such jurisdictions;  provided,  however, that
the  Company  shall not be required in  connection  therewith  or as a condition
thereto to (x)  qualify to do business  in any  jurisdiction  where it would not
otherwise be required to qualify but for this Section 3(d),  (y) subject  itself
to general taxation in any such  jurisdiction,  or (z) file a general consent to
service of process in any such  jurisdiction.  The Company shall promptly notify
each Investor who holds Registrable  Securities of the receipt by the Company of
any  notification  with  respect  to  the  suspension  of  the  registration  or
qualification of any of the Registrable Securities for sale under the securities
or "blue sky" laws of any  jurisdiction  in the United  States or its receipt of
actual  notice of the  initiation  or  threatening  of any  proceeding  for such
purpose.

                  e.    In  the  event  Investors  who  hold a  majority  of the
Registrable Securities being offered in the offering select underwriters for the
offering,  the Company  shall enter into and  perform its  obligations  under an
underwriting  agreement,  in  usual  and  customary  form,  including,   without
limitation,  customary  indemnification and contribution  obligations,  with the
underwriters of such offering; provided, that the Company shall not be obligated
to pay any fees, disbursements or expenses such underwriters incur in connection
with such offering.

                  f.    As promptly as practicable  after becoming aware of such
event, the Company shall notify each Investor in writing of the happening of any
event as a result of which the prospectus included in a Registration  Statement,
as then in effect,  includes an untrue  statement of a material fact or omission
to state a material fact required to be stated  therein or necessary to make the
statements  therein,  in light of the circumstances  under which they were made,
not  misleading,  and  promptly  prepare  a  supplement  or  amendment  to  such
Registration Statement to correct such untrue statement or omission, and deliver
ten (10) copies of such  supplement or amendment to each Investor (or such other
number of copies as such  Investor may  reasonably  request).  The Company shall
also  promptly  notify each  Investor in writing  (i) when a  prospectus  or any
prospectus  supplement or  post-effective  amendment has been filed,  and when a
Registration  Statement or any  post-effective  amendment  has become  effective
(notification  of such  effectiveness  shall be  delivered  to each  Investor by
facsimile on the same day of such  effectiveness and by overnight mail), (ii) of
any request by the SEC for amendments or supplements to a Registration Statement
or  related  prospectus  or  related  information,  and  (iii) of the  Company's
reasonable determination that a post-effective amendment to a Registration


                                       -6-

<PAGE>



Statement would be appropriate. Notwithstanding anything to the contrary in this
Section  3(f),  at any time after the  Registration  Statement has been declared
effective,   the  Company  may  delay  the  disclosure  of  material  non-public
information  concerning  the Company the disclosure of which at the time is not,
in the good  faith  opinion of the Board of  Directors  of the  Company  and its
counsel,  in the best  interest of the Company and, in the opinion of counsel to
the Company,  otherwise required (a "GRACE PERIOD");  provided, that the Company
shall  promptly (i) notify the Investors in writing of the existence of material
non-public  information  giving rise to a Grace Period and the date on which the
Grace Period will begin, and (ii) notify the Investors in writing of the date on
which  the Grace  Period  ends;  and,  provided  further,  that (A)  during  any
consecutive  120 day period,  the Grace  Period  shall not exceed  fifteen  (15)
calendar days in the aggregate,  and (B) during any  consecutive 365 day period,
the Grace  Period  shall  not  exceed  twenty-three  (23)  calendar  days in the
aggregate,  and (C) there has been no Underwriting Lock-Up Period (as defined in
the Securities  Purchase  Agreement) in the 20 day period prior to the Company's
notice to the  Investors  of a Grace  Period.  For purposes of  determining  the
length of a Grace Period above,  the Grace Period shall begin on and include the
date the holders  receive the notice  referred to in clause (i) and shall end on
and include the date the holders  receive the notice referred to in clause (ii).
The provisions of Sections 2(c) and 3(d)(ii) of the  Certificate of Designations
shall not be applicable  during the period of any Grace Period.  Upon expiration
of the Grace Period,  the Company shall again be bound by the first  sentence of
this Section 3(f) with respect to the  information  giving rise thereto.  In the
event there is a Grace Period, the Mandatory  Conversion Date (as defined in the
Certificate of Designation)  shall be delayed two days for each day in the Grace
Period as provided in Section 2(g) of the Certificate of Designation.

                  g.    The  Company  shall use its best  efforts to prevent the
issuance  of  any  stop  order  or  other   suspension  of  effectiveness  of  a
Registration  Statement,  or the suspension of the  qualification  of any of the
Registrable  Securities  for sale in any  jurisdiction  and, if such an order or
suspension  is issued,  to obtain the  withdrawal of such order or suspension at
the earliest  possible moment and to notify each Investor who holds  Registrable
Securities  being  sold  (and,  in the event of an  underwritten  offering,  the
managing  underwriters) of the issuance of such order and the resolution thereof
or its receipt of actual notice of the  initiation  or threat of any  proceeding
for such purpose.

                  h.    The Company shall permit each Investor and a single firm
of counsel designated as selling stockholders' counsel by the Investors who hold
a majority of the Registrable  Securities being sold, to review and comment upon
a Registration  Statement and all amendments  and  supplements  thereto at least
seven  business  days  prior to  their  filing  with  the SEC,  and not file any
document in a form to which such counsel reasonably  objects.  The Company shall
not submit a request for  acceleration  of the  effectiveness  of a Registration
Statement or any amendment or supplement  thereto  without the prior approval of
such counsel, which consent shall not be unreasonably withheld.

                  i.    At the request of the  Investors  who hold a majority of
the Registrable Securities being sold, the Company shall use its best efforts to
furnish, on the date that Registrable


                                       -7-

<PAGE>



Securities are delivered to an underwriter,  if any, for sale in connection with
the Registration  Statement (i) if required by an underwriter,  a letter,  dated
such date, from the Company's  independent  certified public accountants in form
and  substance  as  is  customarily   given  by  independent   certified  public
accountants to underwriters in an underwritten public offering, addressed to the
underwriters,   and  (ii)  an  opinion,  dated  as  of  such  date,  of  counsel
representing the Company for purposes of such Registration  Statement,  in form,
scope and substance as is customarily given in an underwritten  public offering,
addressed to the underwriters and the Investors.

                  j.    The  Company   shall  make   reasonably   available  for
inspection  by (i) any  Investor,  (ii)  any  underwriter  participating  in any
disposition  pursuant to a Registration  Statement,  (iii) one firm of attorneys
and one firm of accountants or other agents retained by the Investors,  and (iv)
one firm of  attorneys  retained  by all such  underwriters  (collectively,  the
"INSPECTORS") all pertinent financial and other records, and pertinent corporate
documents and properties of the Company (collectively,  the "RECORDS"), as shall
be reasonably  deemed  necessary by each  Inspector to enable each  Inspector to
exercise its due diligence  responsibility,  and cause the  Company's  officers,
directors  and  employees  to supply all  information  which any  Inspector  may
reasonably request for purposes of such due diligence;  provided,  however, that
each Inspector shall hold in strict confidence and shall not make any disclosure
(except  to an  Investor)  or use of any Record or other  information  which the
Company determines in good faith to be confidential,  and of which determination
the  Inspectors  are so notified,  unless (a) the  disclosure of such Records is
necessary  to avoid or correct a  misstatement  or omission in any  Registration
Statement or is otherwise  required  under the 1933 Act, (b) the release of such
Records is ordered pursuant to a final,  non-appealable subpoena or order from a
court or government  body of competent  jurisdiction,  or (c) the information in
such  Records  has been made  generally  available  to the public  other than by
disclosure  in violation of this or any other  agreement of which the  Inspector
has  knowledge.  The Company shall not be required to disclose any  confidential
information  in such  Records to an  Inspector  unless and until such  Inspector
shall have  entered  into a  confidentiality  agreement  with the  Company  with
respect  thereto,  substantially in the form of this Section 3(j). Each Investor
agrees that it shall, upon learning that disclosure of such Records is sought in
or by a court or  governmental  body of competent  jurisdiction or through other
means, give prompt notice to the Company and allow the Company,  at its expense,
to  undertake  appropriate  action  to  prevent  disclosure  of,  or to obtain a
protective order for, the Records deemed confidential.

                  k.  The  Company  shall  hold in  confidence  and not make any
disclosure of information  concerning an Investor provided to the Company unless
(i) disclosure of such  information is necessary to comply with federal or state
securities  laws, (ii) the disclosure of such  information is necessary to avoid
or correct a misstatement or omission in any Registration  Statement,  (iii) the
release of such  information  is ordered  pursuant to a subpoena or other final,
non-appealable   order  from  a  court  or   governmental   body  of   competent
jurisdiction,  or (iv) such information has been made generally available to the
public other than by  disclosure  in  violation  of this  Agreement or any other
agreement.  The Company agrees that it shall,  upon learning that  disclosure of
such  information  concerning  an  Investor  is  sought  in  or  by a  court  or
governmental body of competent  jurisdiction or through other means, give prompt
written notice to such Investor and allow such Investor, at the


                                       -8-

<PAGE>



Investor's expense, to undertake appropriate action to prevent disclosure of, or
to obtain a protective order for, such information.

                  l.    The  Company  shall use its best  efforts  either to (i)
cause all the Registrable  Securities covered by a Registration  Statement to be
listed on each  securities  exchange  on which  securities  of the same class or
series  issued by the  Company are then  listed,  if any, if the listing of such
Registrable  Securities is then permitted  under the rules of such exchange,  or
(ii) secure designation and quotation of all the Registrable  Securities covered
by the Registration  Statement on the Nasdaq National Market or, if, despite the
Company's best efforts to satisfy the preceding  clause (i) or (ii), the Company
is  unsuccessful  in satisfying the preceding  clause (i) or (ii), to secure the
inclusion  for  quotation  on The Nasdaq  SmallCap  Market for such  Registrable
Securities,  in either case to the maximum  extent the  inclusion of such shares
are then  permitted  under  the  rules of  Nasdaq,  and,  without  limiting  the
generality  of the  foregoing,  to  arrange  for at least two  market  makers to
register with the National  Association of Securities Dealers,  Inc. ("NASD") as
such with respect to such Registrable Securities. The Company shall pay all fees
and expenses in connection  with  satisfying its  obligation  under this Section
3(l).

                  m.    The Company shall  cooperate with the Investors who hold
Registrable Securities being offered and, to the extent applicable, any managing
underwriter or underwriters,  to facilitate the timely  preparation and delivery
of  certificates   (not  bearing  any  restrictive   legend)   representing  the
Registrable  Securities to be offered  pursuant to a Registration  Statement and
enable such certificates to be in such denominations or amounts, as the case may
be, as the  managing  underwriter  or  underwriters,  if any, or, if there is no
managing  underwriter or underwriters,  the Investors may reasonably request and
registered in such names as the managing underwriter or underwriters, if any, or
the Investors may request.

                  n.    Intentionally omitted.

                  o.    The Company shall provide a transfer agent and registrar
for all such  Registrable  Securities  not later than the effective date of such
Registration Statement.

                  p.    If  requested  by  the  managing   underwriters   or  an
Investor,  the  Company  shall  (i)  immediately  incorporate  in  a  prospectus
supplement  or  post-effective   amendment  such  information  as  the  managing
underwriters  and the Investors agree should be included therein relating to the
sale and distribution of Registrable Securities,  including, without limitation,
information  with respect to the number of Registrable  Securities being sold to
such  underwriters,  the purchase price being paid therefor by such underwriters
and any other terms of the underwritten (or best efforts underwritten)  offering
of the  Registrable  Securities  to be sold  in such  offering;  (ii)  make  all
required filings of such prospectus  supplement or  post-effective  amendment as
soon as notified of the matters to be incorporated in such prospectus supplement
or  post-effective  amendment;  and (iii)  supplement or make  amendments to any
Registration  Statement if requested by an Investor or any  underwriter  of such
Registrable Securities.



                                       -9-

<PAGE>



                  q.    Subject to Section 3(d),  the Company shall use its best
efforts  to  cause  the  Registrable   Securities   covered  by  the  applicable
Registration  Statement  to  be  registered  with  or  approved  by  such  other
governmental  agencies or  authorities  as may be  necessary to  consummate  the
disposition of such Registrable Securities; provided that the Company shall have
no obligation to seek such registration or approval with  governmental  agencies
or authorities outside of the United States.

                  r.    The  Company  shall  make  generally  available  to  its
security  holders  as soon as  practical,  but not later  than 90 days after the
close of the period covered  thereby,  an earnings  statement (in form complying
with the  provisions  of Rule 158 under the 1933 Act)  covering  a  twelve-month
period  beginning not later than the first day of the Company's  fiscal  quarter
next following the effective date of the Registration Statement.

                  s.    The  Company  shall  otherwise  use its best  efforts to
comply with all applicable  rules and  regulations of the SEC in connection with
any registration hereunder.

                  t.    Within  two (2)  business  days  after the  Registration
Statement which includes the Registrable  Securities is ordered effective by the
SEC, the Company shall deliver, and shall cause legal counsel for the Company to
deliver,  to the transfer agent for such Registrable  Securities (with copies to
the Investors  whose  Registrable  Securities are included in such  Registration
Statement)  confirmation  that the  Registration  Statement  has  been  declared
effective by the SEC.

         4.       OBLIGATIONS OF THE INVESTORS.

                  a.    At least  seven (7) days prior to the first  anticipated
filing date of a Registration Statement,  the Company shall notify each Investor
in writing of the  information  the Company  requires from each such Investor in
order to have any of such  Investor's  Registrable  Securities  included in such
Registration  Statement. It shall be a condition precedent to the obligations of
the Company to complete the registration pursuant to this Agreement with respect
to the Registrable  Securities of a particular Investor that such Investor shall
furnish to the  Company  such  information  regarding  itself,  the  Registrable
Securities  held by it and the intended method of disposition of the Registrable
Securities  held by it as shall be  reasonably  required  to timely  effect  the
registration of such Registrable  Securities and shall execute such documents in
connection with such registration as the Company may reasonably request.

                  b.    Each  Investor,  by such  Investor's  acceptance  of the
Registrable  Securities,  agrees to  cooperate  with the  Company as  reasonably
requested by the Company in connection  with the  preparation  and filing of any
Registration Statement hereunder,  unless such Investor has notified the Company
in  writing  of such  Investor's  election  to  exclude  all of such  Investor's
Registrable Securities from such Registration Statement.

                  c.    In the event any Investor  elects to  participate  (as a
condition precedent to such Investor's  participation) in an underwritten public
offering  pursuant  to  Section 2, each such  Investor  agrees to enter into and
perform such Investor's obligations under an underwriting agreement, in usual


                                      -10-

<PAGE>



and customary form, including, without limitation, customary indemnification and
contribution  obligations  (only  with  respect  to  violations  which  occur in
reliance upon and in  conformity  with  information  furnished in writing to the
Company by such  Investor  expressly for use in the  Registration  Statement for
such  underwritten  public  offering),  with the  managing  underwriter  of such
offering  and take such other  actions as are  reasonably  required  in order to
expedite or facilitate the disposition of the Registrable Securities.

                  d.    Each  Investor  agrees that,  upon receipt of any notice
from the Company of the happening of any event of the kind  described in Section
3(g) or the first sentence of 3(f), such Investor will  immediately  discontinue
disposition of Registrable Securities pursuant to any Registration  Statement(s)
covering such Registrable Securities until such Investor's receipt of the copies
of the  supplemented or amended  prospectus  contemplated by Section 3(g) or the
first sentence of 3(f).

                  e.    No  Investor  may   participate   in  any   underwritten
registration  hereunder  unless such Investor (i) agrees to sell such Investor's
Registrable  Securities on the basis provided in any  underwriting  arrangements
approved by the Investors entitled hereunder to approve such arrangements,  (ii)
completes  and executes  all  questionnaires,  powers of attorney,  indemnities,
underwriting  agreements and other documents reasonably required under the terms
of such underwriting arrangements, and (iii) agrees to pay its pro rata share of
all underwriting discounts and commissions.

            5.    EXPENSES OF REGISTRATION.

                  Except as otherwise provided in this Agreement,  all expenses,
other than underwriting discounts and commissions, and fees and disbursements of
counsel  for the  Buyers  in excess  of  $2,000,  incurred  in  connection  with
registrations,   filings  or  qualifications  pursuant  to  Sections  2  and  3,
including,  without  limitation,  all registration,  listing and  qualifications
fees,  printers and accounting  fees, fees and  disbursements of counsel for the
Company and fees and disbursements of counsel for the Buyers up to $2,000, shall
be paid by the Company.

            6.    INDEMNIFICATION.

                  In the event any  Registrable  Securities  are  included  in a
Registration Statement under this Agreement:

                  a.    To the  fullest  extent  permitted  by law,  the Company
agrees to  indemnify,  hold  harmless  and defend each  Investor  who holds such
Registrable Securities, the directors, officers, partners, employees, agents of,
and each Person,  if any, who controls,  any Investor  within the meaning of the
1933 Act or the  Securities  Exchange Act of 1934,  as amended (the "1934 ACT"),
and any  underwriter  (as  defined in the 1933 Act) for the  Investors,  and the
directors  and  officers of, and each Person,  if any,  who  controls,  any such
underwriter  within  the  meaning  of the 1933 Act or the  1934  Act  (each,  an
"INDEMNIFIED PERSON"), against any losses, claims, damages, liabilities,


                                      -11-

<PAGE>



judgments,  fines,  penalties,  charges, costs, attorneys' fees, amounts paid in
settlement  or expenses  (collectively,  "CLAIMS")  incurred  in  investigating,
preparing  or  defending  any  action,   claim,   suit,   inquiry,   proceeding,
investigation  or appeal  taken  from the  foregoing  by or before  any court or
governmental,  administrative  or  other  regulatory  agency,  body or the  SEC,
whether pending or threatened,  whether or not an indemnified party is or may be
a party thereto ("INDEMNIFIED DAMAGES"), to which any of them may become subject
insofar  as such  Claims  (or  actions  or  proceedings,  whether  commenced  or
threatened,  in respect  thereof) arise out of or are based upon: (i) any untrue
statement  or alleged  untrue  statement  of a material  fact in a  Registration
Statement  or any  post-effective  amendment  thereto or in any  filing  made in
connection with the  qualification of the offering under the securities or other
"blue sky" laws of any jurisdiction in which Registrable  Securities are offered
("BLUE SKY  FILING"),  or the  omission or alleged  omission to state a material
fact required to be stated therein or necessary to make the statements  therein,
in light of the circumstances  under which the statements therein were made, not
misleading,  (ii) any untrue statement or alleged untrue statement of a material
fact contained in any preliminary prospectus if used prior to the effective date
of such Registration Statement, or contained in the final prospectus (as amended
or  supplemented,  if the  Company  files any  amendment  thereof or  supplement
thereto with the SEC) or the omission or alleged  omission to state  therein any
material fact  necessary to make the  statements  made therein,  in light of the
circumstances  under which the statements therein were made, not misleading,  or
(iii) any  violation  or alleged  violation  by the Company of the 1933 Act, the
1934 Act, any other law,  including,  without  limitation,  any state securities
law, or any rule or regulation  thereunder  relating to the offer or sale of the
Registrable  Securities pursuant to a Registration Statement (the matters in the
foregoing clauses (i) through (iii) being, collectively,  "VIOLATIONS"). Subject
to the  restrictions  set forth in  Section  6(d) with  respect to the number of
legal  counsel,  the  Company  shall  reimburse  the  Investors  and  each  such
underwriter  or controlling  person,  promptly as such expenses are incurred and
are due and payable,  for any reasonable legal fees or other reasonable expenses
incurred by them in connection with  investigating  or defending any such Claim.
Notwithstanding  anything to the contrary contained herein, the  indemnification
agreement contained in this Section 6(a): (i) shall not apply to a Claim arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information  furnished in writing to the Company by any Indemnified  Person
or underwriter for such Indemnified  Person expressly for use in connection with
the preparation of the Registration  Statement or any such amendment  thereof or
supplement  thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c); (ii) with respect to any preliminary prospectus, shall
not inure to the benefit of any such person from whom the person  asserting  any
such Claim purchased the Registrable Securities that are the subject thereof (or
to the benefit of any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary  prospectus was corrected
in the  prospectus,  as then amended or  supplemented,  if such  prospectus  was
timely  made  available  by the  Company  pursuant  to  Section  3(c),  and  the
Indemnified  Person was  promptly  advised in writing  not to use the  incorrect
prospectus  prior to the use giving  rise to a  violation  and such  Indemnified
Person,  notwithstanding  such advice,  used it; (iii) shall not be available to
the extent  such Claim is based on a failure  of the  Investor  to deliver or to
cause to be delivered the  prospectus  made  available by the Company;  and (iv)
shall not apply to amounts paid in settlement of any Claim if such settlement is
effected  without the prior written consent of the Company,  which consent shall
not be unreasonably withheld. Such


                                      -12-

<PAGE>



indemnity shall remain in full force and effect  regardless of any investigation
made by or on behalf of the Indemnified Person and shall survive the transfer of
the Registrable Securities by the Investors pursuant to Section 9.

                  b.    In connection with any  Registration  Statement in which
an Investor is  participating,  each such  Investor  agrees to severally and not
jointly indemnify,  hold harmless and defend, to the same extent and in the same
manner as is set forth in Section 6(a), the Company, each of its directors, each
of its officers who signs the Registration  Statement,  each Person, if any, who
controls  the  Company  within  the  meaning  of the  1933  Act or the  1934 Act
(collectively and together with an Indemnified Person, an "INDEMNIFIED  PARTY"),
against  any  Claim  or  Indemnified  Damages  to which  any of them may  become
subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or
Indemnified  Damages arise out of or are based upon any Violation,  in each case
to the extent,  and only to the extent,  that such Violation  occurs in reliance
upon and in conformity with written information furnished to the Company by such
Investor  expressly for use in connection with such Registration  Statement or a
failure of the Investor to deliver or cause to be delivered any  preliminary  or
final  prospectus  required to be  delivered  by such  Investor to an offeree or
purchaser of Conversion Shares; and, subject to Section 6(d), such Investor will
reimburse any legal or other expenses  reasonably incurred by them in connection
with  investigating  or defending any such Claim;  provided,  however,  that the
Investor shall be liable under this Section 6(b) for only that amount of a Claim
or Indemnified Damages as does not exceed the net proceeds to such Investor as a
result  of the sale of  Registrable  Securities  pursuant  to such  Registration
Statement.

                  c.    The Company  shall be  entitled  to receive  indemnities
from  underwriters,  selling  brokers,  dealer  managers and similar  securities
industry professionals participating in any distribution,  to the same extent as
provided above, with respect to information such persons so furnished in writing
expressly for inclusion in the Registration Statement.

                  d.    Promptly  after  receipt  by an  Indemnified  Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action or proceeding (including any governmental action or proceeding) involving
a Claim,  such  Indemnified  Person or  Indemnified  Party shall,  if a Claim in
respect thereof is to be made against any indemnifying  party under this Section
6,  deliver  to the  indemnifying  party a written  notice  of the  commencement
thereof, and the indemnifying party shall have the right to participate in, and,
to the  extent  the  indemnifying  party so  desires,  jointly  with  any  other
indemnifying party similarly  noticed,  to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified
Person or the Indemnified Party, as the case may be; provided,  however, that an
Indemnified  Person or Indemnified  Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying  party, if, in
the  reasonable  opinion of counsel  retained  by the  indemnifying  party,  the
representation  by such counsel of the Indemnified  Person or Indemnified  Party
and the  indemnifying  party would be  inappropriate  due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party  represented by such counsel in such  proceeding.  The Company shall
pay reasonable  fees for only one separate legal counsel for the Investors,  and
such legal  counsel  shall be  selected by the  Investors  holding a majority in
interest of the Registrable Securities included


                                      -13-

<PAGE>



in the Registration  Statement to which the Claim relates. The Indemnified Party
or  Indemnified  Person shall  cooperate  fully with the  indemnifying  party in
connection  with any  negotiation  or defense of any such action or claim by the
indemnifying  party and shall furnish to the indemnifying  party all information
reasonably  available  to the  Indemnified  Party or  Indemnified  Person  which
relates  to such  action  or  claim.  The  indemnifying  party  shall  keep  the
Indemnified  Party or  Indemnified  Person fully apprised at all times as to the
status of the defense or any settlement  negotiations  with respect thereto.  No
indemnifying  party shall be liable for any  settlement of any action,  claim or
proceeding  effected without its written consent,  provided,  however,  that the
indemnifying  party shall not  unreasonably  withhold,  delay or  condition  its
consent.  No  indemnifying  party shall,  without the consent of the Indemnified
Party or Indemnified Person,  consent to entry of any judgment or enter into any
settlement or other compromise  which does not include as an unconditional  term
thereof the giving by the  claimant or plaintiff  to such  Indemnified  Party or
Indemnified  Person of a release from all  liability in respect to such claim or
litigation.   Following   indemnification   as  provided  for   hereunder,   the
indemnifying party shall be subrogated to all rights of the Indemnified Party or
Indemnified  Person with  respect to all third  parties,  firms or  corporations
relating to the matter for which  indemnification  has been made. The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any
liability to the Indemnified  Person or Indemnified  Party under this Section 6,
except to the extent that the indemnifying party is prejudiced in its ability to
defend such action.

                  e.    The indemnification of expenses required by this Section
6 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  Indemnified
Damages are incurred.

                  f.    The indemnity  agreements  contained  herein shall be in
addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified  Person  against  the  indemnifying  party or  others,  and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

                  g.    The  indemnification  provisions  contained herein shall
remain in full force and effect  regardless of any  investigation  made by or on
behalf of an Indemnified Party and shall survive the transfer of the Registrable
Securities by the Investors pursuant to Section 9.  Notwithstanding  anything to
the contrary contained herein, the  indemnification  agreement  contained herein
with respect to any preliminary prospectus shall not inure to the benefit of any
Indemnified Party if the untrue statement or omission of material fact contained
in the preliminary prospectus was corrected on a timely basis in the prospectus,
as then amended or supplemented.

            7.    CONTRIBUTION.

                  To the extent any  indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no contribution shall be made under  circumstances where the maker would not
have been  liable for  indemnification  under the fault  standards  set forth in
Section  6; (ii) no  seller  of  Registrable  Securities  guilty  of  fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution  from any seller of Registrable  Securities who was not
guilty of fraudulent misrepresentation;  and (iii) contribution by any seller of
Registrable  Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.

            8.    REPORTS UNDER THE 1934 ACT.

                  With a view to making  available to the Investors the benefits
of Rule  144  promulgated  under  the  1933  Act or any  other  similar  rule or
regulation  of the  SEC  that  may at any  time  permit  the  Investors  to sell
securities of the Company to the public without  registration  ("RULE 144"), the
Company agrees to:

                  a.    make and keep  public  information  available,  as those
terms are understood and defined in Rule 144;

                  b.    file with the SEC in a timely  manner  all  reports  and
other  documents  required  of the  Company  under  the  1934 Act so long as the
Company remains subject to such  requirements  (it being understood that nothing
herein  shall  limit  the  Company's  obligations  under  Section  4(c)  of  the
Securities  Purchase  Agreement)  and the  filing  of  such  reports  and  other
documents is required for the applicable provisions of Rule 144; and

                  c.    furnish to each  Investor so long as such  Investor owns
Registrable  Securities,  promptly upon request,  (i) a written statement by the
Company that it has complied  with the reporting  requirements  of the 1934 Act,
(ii) a copy of the most  recent  annual or  quarterly  report of the Company and
such other reports and  documents so filed by the Company,  and (iii) such other
information as may be reasonably  requested to permit the investors to sell such
securities pursuant to Rule 144 without registration.

            9.    ASSIGNMENT OF REGISTRATION RIGHTS.

                  The  rights  under  this  Agreement  shall  be   automatically
assignable  by the  Investors  to any  transferee  of  all  or  any  portion  of
Registrable  Securities  if:  (i)  the  Investor  agrees  in  writing  with  the
transferee  or assignee to assign such rights,  and a copy of such  agreement is
furnished to the Company within a reasonable  time after such  assignment;  (ii)
the Company is,  within a  reasonable  time after such  transfer or  assignment,
furnished with written notice of (a) the name and address of


                                      -15-

<PAGE>



such  transferee or assignee,  and (b) the securities with respect to which such
registration  rights are being  transferred  or assigned in accordance  with the
terms of the Securities  Purchase  Agreement;  (iii) immediately  following such
transfer  or  assignment  the  further  disposition  of such  securities  by the
transferee or assignee is  restricted  under the 1933 Act and  applicable  state
securities  laws;  (iv) at or before the time the Company  receives  the written
notice  contemplated  by clause (ii) of this sentence the transferee or assignee
agrees  in  writing  with  the  Company  to be  bound  by all of the  provisions
contained herein, including providing the Company with a current address for all
required notices;  (v) such transfer shall have been made in accordance with the
applicable  requirements  of the Securities  Purchase  Agreement;  and (vi) such
transferee shall be an "accredited investor" as that term is defined in Rule 501
of Regulation D promulgated under the 1933 Act.

            10.   AMENDMENT OF REGISTRATION RIGHTS.

                  Provisions of this Agreement may be amended and the observance
thereof may be waived (either  generally or in a particular  instance and either
retroactively  or  prospectively),  only with the written consent of the Company
and  Investors  who hold a  majority  of the then  Registrable  Securities.  Any
amendment or waiver effected in accordance with this Section 10 shall be binding
upon each Investor and the Company.

            11.   MISCELLANEOUS.

                  a.    A  person  or  entity  is  deemed  to  be  a  holder  of
Registrable  Securities  whenever  such  person  or entity  owns of record  such
Registrable  Securities.  If  the  Company  receives  conflicting  instructions,
notices or elections  from two or more  persons or entities  with respect to the
same  Registrable   Securities,   the  Company  shall  act  upon  the  basis  of
instructions,  notice or election  received  from the  registered  owner of such
Registrable Securities.

                  b.    Any notices,  consents,  waivers or other communications
required or permitted to be given under the terms of this  Agreement  must be in
writing  and will be  deemed  to have  been  delivered  (i) upon  receipt,  when
delivered  personally;  (ii) upon  receipt,  when sent by facsimile  (provided a
confirmation of  transmission is mechanically  generated and kept on file by the
sending  party);  (iii) three (3) days after being sent by U.S.  certified mail,
return  receipt  requested;  or (iv) one (1) business  day after  deposit with a
nationally   recognized  overnight  delivery  service,  in  each  case  properly
addressed to the party to receive the same. The addresses and facsimile  numbers
for such communications shall be:

other party of any change in address, phone number or facsimile number.

                  c.    Failure  of any  party to  exercise  any right or remedy
under this Agreement or otherwise,  or delay by a party in exercising such right
or remedy, shall not operate as a waiver thereof.

                  d.    This Agreement  shall be governed by and  interpreted in
accordance  with  the  laws of the  State  of New  York  without  regard  to the
principles  of  conflict  of laws  (other  than  Section  5-1401 of the New York
General   Obligations  Law).  Each  party  hereby  irrevocably  submits  to  the
non-exclusive  jurisdiction  of the state and federal courts sitting the City of

herein,  and hereby  irrevocably  waives,  and agrees not to assert in any suit,
action  or  proceeding,  any  claim  that it is not  personally  subject  to the
jurisdiction of any such court,  that such suit, action or proceeding is brought
in an inconvenient forum or that the venue of such suit, action or proceeding is
improper.  Each party hereby  irrevocably waives personal service of process and
consents  to process  being  served in any such suit,  action or  proceeding  by
mailing a copy thereof to such party at the address for such notices to it under
this Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof.  Nothing contained herein shall be deemed
to limit in any way any right to serve  process in any manner  permitted by law.
If any  provision of this  Agreement  shall be invalid or  unenforceable  in any
jurisdiction,  such invalidity or unenforceability shall not affect the validity
or enforceability of the remainder of this Agreement in that jurisdiction or the
validity or  enforceability  of any  provision  of this  Agreement  in any other
jurisdiction.
