Attention: Bruce Maller, Chairman of the Board

Gentlemen:

         We refer to the Amended and Restated Credit Agreement dated as of
July 1, 1998, as amended, between you and us (the "Credit Agreement"). All
capitalized terms used herein without definition shall have the same meaning
herein as such terms are defined in the Credit Agreement.

         The Borrower has advised the Banks that the Borrower is currently
working on a revised business plan which will include, among other things, a
request to restructure the Obligations owing to the Banks on terms and
conditions mutually agreed upon by the Borrower and the Banks. While the
Borrower and the Banks have initiated discussions concerning the proposed
restructuring of the Obligations, the Borrower acknowledges that the Banks have
not agreed to any terms and conditions relating to any restructuring of the
Obligations. In the meantime, however, the Borrower intends to continue to sell
the remaining physician practice management groups operated by the Borrower and
its Subsidiaries (collectively being referred to herein as the "PPM
Businesses") and use a portion of the proceeds from the sale of the PPM
Businesses to meet its reasonable and necessary operating expenses.

         To afford the Borrower an opportunity to proceed with the transactions
described above, the Borrower has requested that (i) the Banks extend the
temporary waiver period provided for in Sections 2.1 and 2.2 of that certain
Seventh Amendment and Waiver to Credit Agreement dated as of December 10, 1999,
among the Borrower, the Banks, and the Agent (the "Seventh Amendment") (as
further amended, in part, by a December 30, 1999, letter agreement, a February
29, 2000, letter agreement, a March 24, 2000, letter agreement, an April 14,
2000, letter agreement, a May 5, 2000, letter agreement, a May 19, 2000, letter
agreement, a June 1, 2000, letter agreement, a June 9, 2000, letter agreement,
a June 16, 2000, letter agreement, a June 29, 2000, letter agreement, a
July 21, 2000, letter agreement, and an August 11, 2000, letter agreement, in
each case between the Borrower, the Banks and the Agent) and, in addition, that
the Banks temporarily waive any non-compliance by the Borrower as of December
31, 1999, as of March 31, 2000, and as of June 30, 2000, with Sections 8.8
(Total Funded Debt/Adjusted EBITDA Ratio), 8.10 (Interest Coverage Ratio), and
8.11 (Debt Service Coverage Ratio) of the Credit Agreement and the Borrower's
non-compliance with Section 8.5(b) of the Credit Agreement with respect to the
timely delivery of the Borrower's March 31, 2000, financial

statements, in each case to September 29, 2000 (the "Waiver Termination Date"),
(ii) Bank of Montreal extend the Bridge Loan Period from September 8, 2000, to
the Waiver Termination Date, and (iii) amend the due date for the payment of
principal, interest and unused commitment fees otherwise due on or before
August 31, 2000, with respect to the Revolving Credit and the Term Loans
(including such payments described in Sections 2.1 and 2.2 of the Seventh
Amendment) to the Waiver Termination Date. By signing below, the Banks
(including Bank of Montreal with respect to the Bridge Loan Commitment) hereby
agree to extend the waiver period provided in Sections 2.1 and 2.2 of the
Seventh Amendment from September 8, 2000, to the Waiver Termination Date,
temporarily waive any non-compliance by the Borrower as of December 31, 1999,
as of March 31, 2000, and as of June 30, 2000, with Sections 8.8 (Total Funded
Debt/Adjusted EBITDA Ratio), 8.10 (Interest Coverage Ratio), and 8.11 (Debt
Service Coverage Ratio) of the Credit Agreement and the Borrower's
non-compliance with Section 8.5(b) of the Credit Agreement with respect to the
timely delivery of the Borrower's March 31, 2000, financial statements through
the period ending on the Waiver Termination Date, agree to extend the Bridge
Loan Period to the Waiver Termination Date, and agree to amend the due date for
the payment of principal, interest, and unused commitment fees otherwise due on
or before August 31, 2000, with respect to the Revolving Credit and the Term
Loans (including such payments described in Sections 2.1 and 2.2 of the Seventh
Amendment) to the Waiver Termination Date, provided that:

                  (a) until the Obligations are paid in full, the Borrower
         shall provide to the Banks a weekly Budget pursuant to Section 1.14(f)
         of the Credit Agreement and such Budget shall be subject to the
         Approved Budget and reconciliation procedures set forth therein,
         regardless of whether or not then being accompanied by a request for a
         Borrowing of Bridge Loans;

                  (b) at all times on and after the date hereof (i) all
         proceeds from the sale of any assets of the Borrower and its
         Subsidiaries (including, without limitation, proceeds from the sale of
         the PPM Businesses or any part thereof), and (ii) cash receipts
         arising from the operation of the business of the Borrower and its
         Subsidiaries not applied pursuant to an Approved Budget, shall in each
         case be remitted promptly upon receipt to the Agent; and

                  (c) except to the extent applied to payments pursuant to an
         Approved Budget or applied to the Obligations owing to the Banks,
         proceeds received pursuant to clause (c) above shall be held by the
         Agent as collateral for the remaining Obligations owing to the Banks
         (the Agent hereby being granted a Lien on and right of set-off for the
         benefit of the Banks against all such amounts so held).

The Borrower hereby acknowledges and agrees to the foregoing conditions. The
Borrower also hereby acknowledges and agrees that (i) any restructuring of the
terms and conditions relating to

the Obligations shall be subject to the Banks' consent, which may be given or
withheld in their discretion and (ii) any sale of the Borrower's or its
Subsidiaries' assets or businesses shall be subject to the prior written
consent of the Banks, and all proceeds from any such sale represent proceeds of
the Banks' Collateral, to be held by the Agent or applied to the Obligations
pursuant to the terms of the Credit Agreement as modified hereby.

         Except as specifically modified hereby, all of the terms and
conditions of the Credit Agreement and the other Loan Documents shall stand and
remain unchanged and in full force and effect. This waiver shall become
effective upon the execution and delivery hereof by each of the Banks and the
Borrower as set forth below. This waiver may be executed in counterparts and by
different parties on separate counterpart signature pages, each of which shall
be an original and all of which taken together shall constitute one and the
same instrument. This waiver shall be governed by, and construed in accordance
with, the laws of the State of Illinois.

     2.1 REPRESENTATIONS,  WARRANTIES AND AGREEMENTS OF THE COMPANY. The Company
hereby makes the following representations and warranties to the Purchasers:

         (a) ORGANIZATION AND  QUALIFICATION.  The Company is a corporation duly
incorporated,  validly existing and in good standing under the laws of the State
of Nevada with the  requisite  corporate  power and authority to own and use its
properties and assets and to carry on its business as currently  conducted.  The

                                      -3-
<PAGE>
Company  has  no  subsidiaries  other  than  as set  forth  in  SCHEDULE  2.1(A)
(collectively the  "SUBSIDIARIES").  Each of the Subsidiaries is an entity, duly
incorporated or otherwise organized, validly existing and in good standing under
the  laws  of  the  jurisdiction  of  its   incorporation  or  organization  (as
applicable),  with  the  requisite  power  and  authority  to own  and  use  its
properties and assets and to carry on its business as currently conducted.  Each
of the Company and the  Subsidiaries  is duly qualified to do business and is in
good standing as a foreign  corporation in each jurisdiction in which the nature
of the  business  conducted  or  property  owned by it makes such  qualification
necessary,  except where the failure to be so qualified or in good standing,  as
the case may be, could not,  individually  or in the  aggregate,  (x)  adversely
affect the legality,  validity or  enforceability  of the Securities (as defined
below) or any of this Agreement, the Registration Rights Agreement, the Security
Agreement,  the Transfer Agent Instructions or the Warrants  (collectively,  the
"TRANSACTION DOCUMENTS"), (y) have or result in a material adverse effect on the
results of operations,  assets, prospects, or condition (financial or otherwise)
of the Company and the  Subsidiaries,  taken as a whole, or (z) adversely impair
the Company's  ability to perform fully on a timely basis its obligations  under
any of the  Transaction  Documents (any of (x), (y) or (z), a "MATERIAL  ADVERSE
EFFECT").

         (b) AUTHORIZATION; ENFORCEMENT. The Company has the requisite corporate
power  and  authority  to  enter  into  and  to  consummate   the   transactions
contemplated by each of the Transaction Documents and otherwise to carry out its
obligations  thereunder.  The execution and delivery of each of the  Transaction
Documents  by  the  Company  and  the  consummation  by it of  the  transactions
contemplated  thereby have been duly  authorized by all necessary  action on the
part of the Company and no further  action is required by the  Company.  Each of
the  Transaction  Documents  and the  Debentures  has been duly  executed by the
Company and, when  delivered (or filed,  as the case may be) in accordance  with
the terms  hereof,  will  constitute  the valid and  binding  obligation  of the
Company  enforceable  against the Company in accordance with its terms.  Neither
the Company nor any  Subsidiary is in violation of any of the  provisions of its
respective   certificate  or  articles  of   incorporation,   by-laws  or  other
organizational or charter documents.

         (c)  CAPITALIZATION.  The number of authorized,  issued and outstanding
capital  stock of the  Company  is set forth in  SCHEDULE  2.1(C).  No shares of
Common Stock are entitled to preemptive or similar rights,  nor is any holder of
the Common Stock  entitled to  preemptive or similar  rights  arising out of any
agreement or understanding  with the Company by virtue of any of the Transaction
Documents. Except as a result of the purchase and sale of the Debentures and the
Warrants and except as disclosed in SCHEDULE  2.1(C),  there are no  outstanding
options,  warrants,  script rights to subscribe to, calls or  commitments of any
character   whatsoever  relating  to,  or  securities,   rights  or  obligations
convertible  into or  exchangeable  for, or giving any Person (as defined below)
any right to subscribe for or acquire, any shares of Common Stock, or contracts,
commitments,  understandings,  or  arrangements  by  which  the  Company  or any
Subsidiary is or may become bound to issue additional shares of Common Stock, or
securities or rights convertible or exchangeable into shares of Common Stock.

         (d) ISSUANCE OF THE DEBENTURES AND THE WARRANTS. The Debentures and the
Warrants are duly  authorized  and, when issued and paid for in accordance  with
the terms hereof, will be duly and validly issued, fully paid and nonassessable,
free and clear of all liens,  encumbrances  and  rights of first  refusal of any
kind  (collectively,  "LIENS").  The Company has on the date hereof and will, at

                                      -4-
<PAGE>
all times while the  Debentures  and the Warrants are  outstanding,  maintain an
adequate  reserve  of duly  authorized  shares of  Common  Stock,  reserved  for
issuance  to the holders of the  Debentures  and the  Warrants,  to enable it to
perform its conversion, exercise and other obligations under this Agreement, the
Debentures  and the Warrants.  Such number of reserved and  available  shares of
Common  Stock is not less  than the sum of (i) 200% of the  number  of shares of
Common Stock which would be issuable upon  conversion in full of the Debentures,
assuming such  conversion  occurred on the Original  Issue Date,  the Debentures
remain  outstanding  for two years and all  interest is paid in shares of Common
Stock and (ii) the number of shares of Common Stock  issuable  upon  exercise of
the Warrants (such number of shares of Common Stock as  contemplated  in clauses
(i)-(ii),  the "INITIAL  MINIMUM").  All such authorized  shares of Common Stock
shall be duly  reserved  for issuance to the holders of the  Debentures  and the
Warrants.  The shares of Common Stock issuable upon conversion of the Debentures
and upon  exercise of the  Warrants are  collectively  referred to herein as the
"UNDERLYING SHARES." The Debentures,  the Warrants and the Underlying Shares are
collectively  referred to herein as, the "SECURITIES." When issued in accordance
with  the  Debentures  and the  Warrants,  the  Underlying  Shares  will be duly

affects or challenges  the legality,  validity or  enforceability  of any of the
Transaction  Documents or the Securities or (ii) could,  individually  or in the
aggregate,  have or result in a Material  Adverse  Effect.  Notwithstanding  the
foregoing to the  contrary,  the  Purchasers  have been apprised of and provided
copies of all complaints and answers filed through the date hereof in connection
with that certain  action filed in the United States  District  Court,  Southern
District of New York as Case No. 99 Civ.  10625 (LMM)  entitled GEM  MANAGEMENT,
LTD. AND SUCCESSWAY HOLDINGS LTD.,  PLAINTIFFS V. ACCORD ADVANCED  TECHNOLOGIES,

defined in such agreements).

warranties  of the  Purchasers  set forth in  Sections  2.2(b)-(g),  the  offer,

its capital stock.

investment  banker,  bank or  other  Person  with  respect  to the  transactions
contemplated  by this  Agreement.  The Purchasers  shall have no obligation with
respect to any fees or with  respect to any claims made by or on behalf of other
Persons  for  fees of a type  contemplated  in this  Section  that may be due in
connection with the  transactions  contemplated  by this Agreement.  The Company

directors,  agents,  and partners,  and their  respective  Affiliates,  from and
against all claims,  losses,  damages, costs (including the costs of preparation

existing fees, as such fees and expenses are incurred.

original principal amount of $1,000,000 (the "SBA LOAN").

forth in the SEC Documents, the Company has not, in the six months preceding the
date  hereof,  received  notice  (written  or oral) from the NASDAQ or any other
stock exchange,  market or trading  facility on which the Common Stock is or has
been  listed (or on which it has been  quoted) to the effect that the Company is
not in compliance with the listing or maintenance  requirements of such exchange
or market.  The Company is, and has no reason to believe that it will not in the
foreseeable  future  continue  to be, in  compliance  with all such  listing and
maintenance requirements.

         (s) PATENTS AND  TRADEMARKS.  The  Company  and its  Subsidiaries  have
rights  to  use,  all  patents,  patent  applications,   trademarks,   trademark
applications,  service marks, trade names, copyrights, licenses and rights which
are  necessary  or  material  for  use  in  connection  with  their   respective
businesses,  as described in the SEC  Documents and which the failure to so have
would have a Material Adverse Effect (collectively,  the "INTELLECTUAL  PROPERTY
RIGHTS").  To the best knowledge of the Company, all such Intellectual  Property
Rights are enforceable  and there is no existing  infringement by another Person
of any of the Intellectual Property Rights.

         (t) REGISTRATION RIGHTS;  RIGHTS OF PARTICIPATION.  Except as set forth
on  SCHEDULE  6(B) to the  Registration  Rights  Agreement,  the Company has not

certificates,  authorizations  and permits  issued by the  appropriate  federal,
state or foreign  regulatory  authorities  necessary to conduct their respective
businesses  as  described  in the SEC  Documents,  except  where the  failure to
possess such permits could not, individually or in the aggregate, have or result
in a Material Adverse Effect ("MATERIAL  PERMITS"),  and neither the Company nor
any such  Subsidiary  has  received  any notice of  proceedings  relating to the
revocation or modification of any Material Permit.

         (v) TITLE.  The Company and the  Subsidiaries  have good and marketable
title in fee simple to all real property  owned by them which is material to the
business of the Company and its  Subsidiaries  and good and marketable  title in

all  personal  property  owned by them which is material to the  business of the
Company and its Subsidiaries,  in each case free and clear of all Liens,  except
for Liens granted to the Purchasers  pursuant to the Security  Agreement and for
other Liens 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 and its Subsidiaries.  Any real property and facilities held under lease
by the Company and its Subsidiaries are held by them under valid, subsisting and
enforceable  leases of which the Company and its  Subsidiaries are in compliance
and do not interfere  with the use made and proposed to be made of such property
and buildings by the Company and its Subsidiaries.

         (w)  ABSENCE OF CERTAIN  PROCEEDINGS.  Except as  described  in the SEC
Reports,  (i) there is no Action  pending or, to the  knowledge  of the Company,
threatened  against  the  Company,  in any  such  case  wherein  an  unfavorable

of breach of fiduciary duty;  (iii) the Company does not have pending before the
Commission any request for confidential treatment of information and the Company
has no knowledge  of any  expected  such request that would be made prior to the
Effectiveness Date (as defined in the Registration  Rights Agreement);  and (iv)
there  has not been,  and to the best of the  Company's  knowledge  there is not
pending or  contemplated,  any  investigation  by the  Commission  involving the
Company or any current or former director or officer of the Company.

         (x) LABOR  RELATIONS.  No  material  labor  problem  exists  or, to the
knowledge of the Company,  is imminent  with respect to any of the  employees of
the Company.

         (y)  DISCLOSURE.  The Company  confirms  that  neither it nor any other
Person acting on its behalf has provided any of the  Purchasers or its agents or
counsel with any  information  that  constitutes  or might  constitute  material
non-public information. The Company understands and confirms that the Purchasers
shall be relying on the foregoing  representations in effecting  transactions in
securities of the Company.  All disclosure provided to the Purchasers  regarding
the Company, its business and the transactions  contemplated  hereby,  including
the  Schedules to this  Agreement,  furnished by or on behalf of the Company are

therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.

     2.2 REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS. Each Purchaser hereby
for itself and for no other Purchaser  represents and warrants to the Company as
follows:

         (a)  ORGANIZATION;   AUTHORITY.   Such  Purchaser  is  an  entity  duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction  of its  organization  with the requisite  corporate or partnership
power  and  authority  to  enter  into  and  to  consummate   the   transactions
contemplated  by the  Transaction  Documents  and  otherwise  to  carry  out its
obligations  thereunder.  The  purchase  by  such  Purchaser  of the  Securities
hereunder has been duly  authorized by all necessary  action on the part of such
Purchaser.  Each of this  Agreement,  the  Registration  Rights  Agreement,  the
Security  Agreement and the Intellectual  Property  Security  Agreement has been
duly  executed  by such  Purchaser,  and when  delivered  by such  Purchaser  in
accordance with the terms hereof,  will constitute the valid and legally binding
obligation of such  Purchaser,  enforceable  against it in  accordance  with its
terms.

         (b)  INVESTMENT  INTENT.  Such Purchaser is acquiring the Securities as
principal for its own account for  investment  purposes only and not with a view
to or for distributing or reselling such Securities or any part thereof, without
prejudice, however, to such Purchaser's right, subject to the provisions of this
Agreement  and  the  Registration  Rights  Agreement,  at all  times  to sell or
otherwise dispose of all or any part of such Securities pursuant to an effective
registration   statement  under  the  Securities  Act  and  in  compliance  with
applicable  federal and state  securities  laws or under an exemption  from such
registration.  Nothing  contained  herein  shall be deemed a  representation  or
warranty by such Purchaser to hold Securities for any amount of time.

         (c)  PURCHASER  STATUS.  At the time such  Purchaser  was  offered  the
Debentures  and its respective  Warrants,  it was, and at the date hereof it is,
and at each  exercise  date  under  its  respective  Warrants,  it will  be,  an
"accredited  investor" as defined in Rule 501(a) under the Securities  Act. Such
Purchaser  has  not  been  formed  solely  for  the  purpose  of  acquiring  the
Securities.

         (d)  EXPERIENCE  OF SUCH  PURCHASER.  Such  Purchaser,  either alone or
together  with its  representatives,  has  such  knowledge,  sophistication  and
experience in business and  financial  matters so as to be capable of evaluating
the merits and risks of the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment.

         (e)  ABILITY  OF SUCH  PURCHASER  TO  BEAR  RISK  OF  INVESTMENT.  Such
Purchaser is able to bear the economic risk of an  investment in the  Securities
and, at the present time, is able to afford a complete loss of such investment.

         (f) ACCESS TO  INFORMATION.  Such  Purchaser  acknowledges  that it has
reviewed the Disclosure  Materials and has been afforded (i) the  opportunity to
ask such questions as it has deemed  necessary of, and to receive  answers from,
representatives  of the  Company  concerning  the  terms and  conditions  of the
offering  of the  Securities  and the  merits  and  risks  of  investing  in the
Securities;  (ii) access to  information  about the  Company  and the  Company's
financial condition, results of operations, business, properties, management and
prospects  sufficient  to enable it to evaluate  its  investment;  and (iii) the
opportunity to obtain such additional information which the Company possesses or

                                      -10-
<PAGE>
can acquire without  unreasonable effort or expense that is necessary to make an
informed  investment  decision with respect to the  investment and to verify the
accuracy  and  completeness  of the  information  contained  in  the  Disclosure
Materials. Neither such inquiries nor any other investigation conducted by or on
behalf of such Purchaser or its  representatives or counsel shall modify,  amend
or affect such Purchaser's right to rely on the truth, accuracy and completeness
of the  Disclosure  Materials and the Company's  representations  and warranties
contained in the Transaction Documents.

         (g)  GENERAL  SOLICITATION.   Such  Purchaser  is  not  purchasing  the
Securities as a result of or subsequent to any advertisement, article, notice or
other  communication  regarding  the  Securities  published  in  any  newspaper,
magazine or similar media or broadcast over  television or radio or presented at
any seminar or any other general solicitation or general advertisement.

         (h) RELIANCE.  Such Purchaser understands and acknowledges that (i) the
Securities  are being  offered  and sold to it  without  registration  under the
Securities  Act in a  private  placement  that is exempt  from the  registration
provisions of the Securities Act and (ii) the  availability  of such  exemption,
depends in part on, and the Company will rely upon the accuracy and truthfulness
of, the foregoing  representations  and such Purchaser  hereby  consents to such
reliance.

     The Company acknowledges and agrees that no Purchaser makes or has made any
representations  or  warranties  with respect to the  transactions  contemplated
hereby other than those specifically set forth in this Section 2.2.

                                   ARTICLE III
                         OTHER AGREEMENTS OF THE PARTIES

     3.1 TRANSFER RESTRICTIONS.  (a) Securities may only be disposed of pursuant
to an effective  registration statement under the Securities Act, to the Company
or pursuant to an available  exemption  from or in a transaction  not subject to
the registration  requirements of the Securities Act, and in compliance with any
applicable federal and state securities laws. In connection with any transfer of
Securities other than pursuant to an effective  registration statement or to the
Company,  except as  otherwise  set forth  herein,  the  Company may require the
transferor  thereof to provide to the Company an opinion of counsel  selected by
the  transferor,  the form and  substance of which  opinion  shall be reasonably
satisfactory  to the Company,  to the effect that such transfer does not require
registration  of  such   transferred   securities   under  the  Securities  Act.
Notwithstanding the foregoing, the Company, without requiring a legal opinion as
described in the immediately  preceding sentence,  hereby consents to and agrees
to  register on the books of the  Company  and with any  transfer  agent for the
securities  of the  Company  any  transfer of  Securities  by a Purchaser  to an
Affiliate of such  Purchaser or to one or more funds or managed  accounts  under
common  management  with  such  Purchaser,  and  any  transfer  among  any  such
Affiliates  or  one or  more  funds  or  managed  accounts,  provided  that  the
transferee  certifies  to the Company  that it is an  "accredited  investor"  as
defined in Rule 501(a) under the  Securities  Act and that it is  acquiring  the
Securities  solely  for  investment  purposes  (subject  to  the  qualifications
hereof).  Any such transferee shall agree in writing to be bound by the terms of

                                      -11-
<PAGE>
this Agreement and shall have the rights of a Purchaser under this Agreement and
the Registration Rights Agreement.

         (b) The Purchasers  agree to the imprinting,  so long as is required by
this Section 3.1(b), of the following legend on the Securities:

                  NEITHER THESE  SECURITIES NOR THE SECURITIES  INTO WHICH THESE
         SECURITIES ARE  [CONVERTIBLE]  [EXERCISABLE]  HAVE BEEN REGISTERED WITH
         THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES  COMMISSION OF
         ANY STATE IN RELIANCE  UPON AN EXEMPTION  FROM  REGISTRATION  UNDER THE
         SECURITIES  ACT OF  1933,  AS  AMENDED  (THE  "SECURITIES  ACT"),  AND,
         ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE
         REGISTRATION  STATEMENT  UNDER THE  SECURITIES  ACT OR  PURSUANT  TO AN
         AVAILABLE  EXEMPTION  FROM,  OR IN A  TRANSACTION  NOT  SUBJECT TO, THE
         REGISTRATION  REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
         APPLICABLE STATE SECURITIES LAWS.

         Underlying  Shares shall not contain the legend set forth above nor any
other legend if the  conversion  of  Debentures  and exercise of the Warrants or
other issuances of Underlying  Shares as contemplated  hereby, by the Debentures
or the  Warrants  occurs at any time  while an  Underlying  Shares  Registration
Statement is effective under the Securities Act or, in the event there is not an
effective Underlying Shares Registration Statement, at such time, in the opinion
of  counsel  to the  Company,  such  legend  is not  required  under  applicable
requirements  of the  Securities  Act (including  judicial  interpretations  and
pronouncements  issued by the staff of the Commission).  The Company shall cause
its  counsel  to  issue  the  legal  opinion  included  in  the  Transfer  Agent
Instructions  to the  Company's  transfer  agent on the day that the  Underlying
Shares  Registration  Statement  is declared  effective by the  Commission.  The
Company agrees that, in the event any Underlying Shares are issued with a legend
in accordance with this Section 3.1(b),  it will, within five Trading Days after
request  therefor by a Purchaser,  provide such  Purchaser with a certificate or
certificates  representing such Underlying Shares, free from such legend at such
time as such legend would not have been required  under this Section  3.1(b) had
such issuance occurred on the date of such request. The Company may not make any
notation  on its  records  or give  instructions  to any  transfer  agent of the
Company which enlarge the restrictions of transfer set forth in this Section.

     3.2 ACKNOWLEDGMENT OF DILUTION.  The Company acknowledges that the issuance
of the  Underlying  Shares upon (i)  conversion of the  Debentures in accordance
with  the  terms  of the  Debentures,  and  (ii)  exercise  of the  Warrants  in
accordance with their terms,  will result in dilution of the outstanding  shares
of  Common  Stock,  which  dilution  may be  substantial  under  certain  market
conditions.  The  Company  further  acknowledges  that its  obligation  to issue
Underlying  Shares upon (x) conversion of the Debentures in accordance  with the
terms of the  Debentures,  and (y) exercise of the Warrants in  accordance  with
their terms, is unconditional and absolute, subject to the limitations set forth
herein in the  Debentures or pursuant to the Warrants,  regardless of the effect
of any such dilution.

                                      -12-

     3.3 FURNISHING OF  INFORMATION.  As long as the Purchasers own  Securities,
the Company  covenants to timely file (or obtain  extensions in respect  thereof
and file within the applicable grace period) all reports required to be filed by
the  Company  after the date hereof  pursuant  to Section  13(a) or 15(d) of the
Exchange Act. As long as the  Purchasers own  Securities,  if the Company is not
required to file reports pursuant to such sections,  it will prepare and furnish
to the  Purchasers  and make publicly  available in accordance  with Rule 144(c)
promulgated  under the  Securities  Act such  information as is required for the
Purchasers  to  sell  the  Securities  under  Rule  144  promulgated  under  the
Securities  Act. The Company  further  covenants  that it will take such further
action as any holder of Securities  may  reasonably  request,  all to the extent
required  from time to time to enable  such  Person  to sell  Underlying  Shares
without  registration  under the  Securities  Act within the  limitation  of the
exemptions  provided by Rule 144 promulgated under the Securities Act, including
the legal opinion referenced above in this Section. Upon the request of any such
Person,  the Company shall deliver to such Person a written  certification  of a
duly authorized officer as to whether it has complied with such requirements.

     3.4  INTEGRATION.  The Company shall not, and shall use its best efforts to
ensure that, no Affiliate of the Company shall,  sell, offer for sale or solicit
offers to buy or  otherwise  negotiate in respect of any security (as defined in
Section 2 of the Securities Act) that would be integrated with the offer or sale
of the  Securities  in a manner that would  require the  registration  under the
Securities Act of the sale of the Securities to the Purchasers.

     3.5 INCREASE IN AUTHORIZED  SHARES. If on any date the Company would be, if
a notice of  conversion or exercise (as the case may be) were to be delivered on
such date,  precluded  from (a)  issuing  (a) 200% of the  number of  Underlying
Shares as would then be issuable  upon a conversion  in full of the  Debentures,
and (b) the number of  Underlying  Shares  issuable upon exercise in full of the
Warrants  (the  "CURRENT  REQUIRED  MINIMUM"),   in  either  case,  due  to  the
unavailability  of a sufficient  number of  authorized  but unissued or reserved
shares of  Common  Stock,  then the  Board of  Directors  of the  Company  shall
promptly  (and in any case,  within 30 Business Days from such date) prepare and
mail to the stockholders of the Company proxy materials requesting authorization
to amend the Company's  certificate or articles of incorporation to increase the
number of shares of Common Stock which the Company is  authorized to issue to at
least such number of shares as reasonably  requested by the  Purchasers in order
to provide for such number of authorized and unissued  shares of Common Stock to
enable  the  Company  to  comply  with its  issuance,  conversion  exercise  and
reservation of shares obligations as set forth in this Agreement, the Debentures
and the  Warrants  (the sum of (x) the  number of shares  of Common  Stock  then
outstanding  plus all  shares of Common  Stock  issuable  upon  exercise  of all
outstanding options,  warrants and convertible instruments,  and (y) the Current
Required Minimum,  shall be a reasonable number). In connection  therewith,  the
Board of Directors shall (a) adopt proper resolutions authorizing such increase,
(b)  recommend to and otherwise use its best efforts to promptly and duly obtain
stockholder  approval to carry out such  resolutions (and hold a special meeting
of the  stockholders  no later  than the  earlier to occur of the 60th day after
delivery of the proxy materials  relating to such meeting and the 90th day after
request by a holder of Securities  to issue the number of  Underlying  Shares in
accordance with the terms hereof) and (c) within five Business Days of obtaining
such stockholder  authorization,  file an appropriate amendment to the Company's
certificate or articles of incorporation to evidence such increase.

     3.6 RESERVATION AND LISTING OF UNDERLYING SHARES. (a) The Company shall (i)
in the time and manner required by any national securities exchange or market or
trading or quotation facility on which the Common Stock is then traded,  prepare
and file with such national  securities exchange or market or quotation facility
on which the Common  Stock is then  listed  for  trading  an  additional  shares
listing  application  covering a number of shares of Common  Stock  which is not
less than the  Initial  Minimum,  (ii) take all steps  necessary  to cause  such
shares  of  Common  Stock  to be  approved  for  listing  on any  such  national

Common Stock is then listed as soon as possible thereafter, and (iii) provide to
the  Purchasers  evidence of such listing,  and the Company  shall  maintain the
listing of its Common Stock thereon. If the number of Underlying Shares issuable
upon conversion in full of the then outstanding  Debentures and upon exercise of
the then  unexercised  portion  of the  Warrants  exceeds  85% of the  number of
Underlying  Shares  previously  listed on account thereof with any such required
exchanges),  then the Company  shall take the necessary  actions to  immediately
list a number of  Underlying  Shares  as  equals  no less than the then  Current
Required Minimum.

         (b) The Company shall  maintain a reserve of shares of Common Stock for
issuance upon  conversion of the Debentures in full and upon exercise in full of
the Warrants in accordance with this Agreement, the Debentures and the Warrants,
respectively,  in such amount as may be required to fulfill its  obligations  in
full under the Transaction Documents, which reserve shall equal no less than the
then Current Required Minimum.

     3.7 CONVERSION AND EXERCISE  PROCEDURES.  The Transfer Agent  Instructions,
Conversion  Notice (as defined in the  Debentures)  and Notice of Exercise under
the  Warrants  set forth the  totality  of the  procedures  with  respect to the
conversion of the Debentures and exercise of the Warrants, including the form of
legal opinion,  if necessary,  that shall be rendered to the Company's  transfer
agent and such other information and instructions as may be reasonably necessary
to enable the Purchasers to convert their Debentures and exercise their Warrants
as contemplated in the Debentures and the Warrants (as applicable).

     3.8 CONVERSION AND EXERCISE  OBLIGATIONS OF THE COMPANY.  The Company shall
honor  conversions  of the  Debentures  and  exercises of the Warrants and shall

day following  the  Effective  Date (such date will be extended by the number of
days  after  the  Effectiveness  Date (as  defined  in the  Registration  Rights
Agreement)  that an  Underlying  Shares  Registration  Statement  has  not  been
declared  effective  by the  Commission  and by the  number  of days  after  the
Effective  Date during which a Purchaser  is not  permitted or unable to utilize
the  prospectus or otherwise to resell  Underlying  Shares under the  Underlying
Shares Registration  Statement) (the "RESTRICTED PERIOD"),  the Company will not

any offer,  sale,  grant or any option to purchase or other  disposition) any of
its securities  (including  the issuance of any debt or other  instrument at any
time over the life thereof convertible into or exchangeable for Common Stock) or

                                      -14-
<PAGE>
any of its Affiliate's  securities that may be exchangeable or convertible  into
Common  Stock,  or  otherwise  enter into any other  transaction  intended to be
exempt or not subject to registration under the Securities Act (collectively,  a
"SUBSEQUENT  PLACEMENT"),  unless none of the  securities  issued or granted (or
securities  issuable  upon  conversion  or  exercise  thereof)  may be resold or
registered for issuance or resale under the Securities Act until the termination
of the Restricted  Period.  The restriction  contained in the foregoing sentence
shall not  apply to (i)  issuances  of  Common  Stock  pursuant  to a  Strategic

heretofore or hereinafter duly adopted by the Company ("OPTION PLAN ISSUANCES").
A "STRATEGIC  TRANSACTION" shall mean a transaction or relationship in which the
Company  issues  shares of Common Stock to a Person which is,  itself or through
its subsidiaries,  an operating company in a business related to the business of
the Company and in which the Company receives  material  benefits in addition to
the  investment  of  funds,  but shall not  include a  transaction  in which the
Company is issuing securities primarily for the purpose of raising capital or to
an entity whose primary business is investing in securities.

day following the Effective Date, the Company shall not,  directly or indirectly
enter into a Subsequent  Placement,  unless: (A) the Company delivers to each of
the  Purchasers  a written  notice (the  "SUBSEQUENT  PLACEMENT  NOTICE") of its
intention to effect such Subsequent Placement, which Subsequent Placement Notice
shall  describe  in  reasonable  detail the  proposed  terms of such  Subsequent
Placement,  the amount of proceeds intended to be raised thereunder,  the Person
with whom such  Subsequent  Placement  shall be effected,  and attached to which
shall  be a term  sheet  or  similar  document  relating  thereto  and (B)  such
Purchaser  shall not have notified the Company by 6:30 p.m. (New York City time)
on the tenth Trading Day after its receipt of the Subsequent Placement Notice of
its  willingness to provide (or to cause its sole designee to provide),  subject
to completion of mutually acceptable documentation,  financing to the Company on
the same terms set forth in the Subsequent  Placement  Notice. If the Purchasers
shall  fail to  notify  the  Company  of  their  intention  to enter  into  such
negotiations  within such time  period,  the  Company may effect the  Subsequent
Placement substantially upon the terms and to the Persons (or Affiliates of such
Persons)  set  forth in the  Subsequent  Placement  Notice,  PROVIDED,  that the
Company shall provide the Purchasers with a second Subsequent  Placement Notice,
and the  Purchasers  shall again have the right of first refusal set forth above
in this  paragraph  (b),  if the  Subsequent  Placement  subject to the  initial
Subsequent  Placement  Notice shall not have been  consummated for any reason on
the terms set forth in such  Subsequent  Placement  Notice within thirty Trading
Days after the date of the initial  Subsequent  Placement Notice with the Person
(or an Affiliate of such Person) identified in the Subsequent  Placement Notice.
If the Purchasers shall indicate a willingness to provide financing in excess of
the amount set forth in the  Subsequent  Placement  Notice,  then each Purchaser
shall be entitled to provide  financing  pursuant to such  Subsequent  Placement
Notice  up to an  amount  equal  to such  Purchaser's  pro-rata  portion  of the
aggregate number of Shares purchased by such Purchaser under this Agreement, but
the Company shall not be required to accept  financing from the Purchasers in an
amount in excess of the amount set forth in the Subsequent Placement Notice. The
restrictions of this subsection  shall not apply to: (i) a Subsequent  Placement
in which the securities  (and  securities  issuable upon  conversion or exercise

                                      -15-

registered  for issuance or resale for at least 365 days  following the issuance
date thereof,  (ii)  issuances of shares of Common Stock pursuant to a Strategic
Transaction,  (iii)  issuances  of  shares  of Common  Stock as  payment  of the
purchase price for an acquisition of assets or stock of an  unaffiliated  Person
and (iv) Option Plan Issuances.

registered, and securities of the Company permitted pursuant to Schedule 6(b) of
the Registration's  Rights Agreement to be registered,  in the Underlying Shares
Registration Statement in accordance with the Registration Rights Agreement, and
(z) Common Stock permitted to be issued  pursuant to paragraph  (a)(i)- (iii) of
Section 3.9(a),  the Company shall not, for a period of not less than 90 Trading
Days  after  the date  that the  Underlying  Shares  Registration  Statement  is
declared  effective by the Commission,  without the prior written consent of the
Purchasers  (i)  issue or sell any of its or any of its  Affiliates'  equity  or
equity-equivalent  securities  pursuant to  Regulation S  promulgated  under the
Securities Act, or (ii) register any securities of the Company.  Any days that a
Purchaser  is unable to sell  Underlying  Shares  under  the  Underlying  Shares
Registration Statement shall be added to such 90 Trading Day period.

unreasonably withheld or delayed, except that no prior consent shall be required
if such  disclosure is required by law, in which such case the disclosing  party
shall provide the other party with prior notice of such public statement, filing
or other  communication.  Notwithstanding  the foregoing,  the Company shall not
publicly  disclose  the names of the  Purchasers,  or  include  the names of the
Purchasers in any filing with the Commission,  or any regulatory agency, trading

except  to  the  extent  such  disclosure  (but  not  any  disclosure  as to the
controlling Persons thereof) is required by law, in which case the Company shall

written consent of the Purchasers.

outstanding litigation.

negligence  or willful  misconduct,  becomes  involved  in any  capacity  in any
action,  proceeding or investigation brought by or against any Person, including

consummation  of the  transactions  contemplated by Transaction  Documents,  the
Company  will  reimburse  such  Purchaser  for its  reasonable  legal  and other
expenses  (including the cost of any investigation and preparation)  incurred in
connection  therewith,  as such expenses are incurred.  In addition,  other than

<PAGE>
delivered to the other  party,  it being  understood  that both parties need not
sign the same  counterpart.  In the event that any  signature  is  delivered  by
facsimile  transmission,  such  signature  shall  create  a  valid  and  binding
obligation  of the  party  executing  (or on  whose  behalf  such  signature  is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

     4.11  SEVERABILITY.  In case  any one or  more  of the  provisions  of this

any such obligation the defense that a remedy at law would be adequate.

Transaction  Document,  and no action taken by any Purchaser  pursuant  thereto,
shall be deemed to constitute the Purchasers as a partnership, an association, a
joint  venture  or any other kind of entity,  or create a  presumption  that the
Purchasers are in any way acting in concert with respect to such  obligations or
the transactions  contemplated by the Transaction Document. Each Purchaser shall
be entitled to independently  protect and enforce its rights,  including without
limitation  the  rights  arising  out of  this  Agreement  or  out of the  other

diligence  conducted in connection  with the  contemplated  transaction  and the
representations and warranties of the Company.
