ITEM 1.  SECURITY AND ISSUER

         The title of the class of equity  securities  to which  this  statement
relates is shares of the Common Stock of Cayenne Software,  Inc. a Massachusetts
corporation (the "Issuer").  The address of the principal  executive  offices of
the Issuer is:

         8 New England Executive Park
         Burlington, M  01803


ITEM 2.  IDENTITY AND BACKGROUND

         This statement is being filed by Integral Capital Management III, L.P.,
a Delaware limited partnership ("ICM3").  The principal business address of ICM3
is 2750 Sand Hill Road,  Menlo  Park,  California  94025.  The  names,  business
addresses,  occupations and citizenships of all the general partners of ICM3 are
set forth on Exhibit B hereto.

         ICM3 is the general partner of Integral  Capital  Partners III, L.P., a
Delaware limited  partnership  ("ICP3"),  and the investment  general partner of
Integral  Capital  Partners  International  III, L.P., a Cayman Islands exempted
limited partnership ("ICPI3").  ICP3 and ICPI3 are private investment funds that
invest in securities of publicly traded and private companies,  predominantly in
the areas of information  sciences and life  sciences.  With respect to ICM3 and
the general  partners of ICM3, this statement  relates only to ICM3's  indirect,
beneficial  ownership of shares of the Series D Convertible  Preferred  Stock of
the Issuer (the  "Series D Preferred  Stock")  and  warrants to purchase  Common
Stock of the Issuer (the "Warrant Stock") (collectively,  the Series D Preferred
Stock and Warrant Stock are referred to herein as the "Shares") . ICP3 and ICPI3
hold 81,550 shares and 18,450 shares of Series D Preferred Stock,  respectively.
Each share of the Series D Preferred Stock is convertible  into shares of Common
Stock from time to time at a rate  determined  by the lesser of (a) the lower of
(1) the average quoted market price of the Common Stock for the ten trading days
preceding  the date of  issuance  and (2) the  lower of (x) the  average  quoted
market price of the Common Stock for the ten trading days immediately  preceding
any issuance of Common Stock (or Common Stock  equivalents)  by the Issuer prior
to November 26, 1997 and (y) the price at which the Common Stock is so issued or
may be issued on conversion or exercise of the Common Stock equivalent,  and (b)
the lowest  average  quoted  market  prices for any five trading days during the
period of thirty days before the conversion. The amount of Common Stock shown in
this  Schedule  13D  reflects  the amount into which the full amount of Series D
Preferred  Stock might have been converted on August 28, 1997 in accordance with
the market-price formula. Because the number of shares of Common Stock that will
be ultimately issued to ICP3 and ICPI3 upon conversion of the Series D Preferred
stock is dependent  upon the conversion  formula  described  above,  that amount
cannot be  determined at this time but will  determined  upon the date of actual
conversion.

         The shares of Series D Preferred  Stock and the Warrant Stock have been
purchased  by ICP3 and ICPI3,  and none of ICM3 or the general  partners of ICM3
directly or otherwise hold any shares of capital stock of the Issuer. Management
of the business  affairs of ICM3,  including  decisions  respecting  disposition
and/or voting of the shares of Series D Preferred  Stock,  resides in a majority
of the general partners of ICM3 listed on Exhibit B, such that no single general
partner of ICM3 has voting and/or dispositive power of the Shares.

                                                                    Page 6 of 38

         To the best of ICM3's knowledge,  none of the persons listed on Exhibit
B  hereto  has,  during  the last  five  years,  been  convicted  in a  criminal
proceeding  (excluding  traffic  violations or similar  misdemeanors)  or been a
party to a civil  proceeding of a judicial or  administrative  body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree  or final  order  enjoining  future  violations  of,  or  prohibiting  or
mandating  activities subject to federal or state securities laws or finding any
violation with respect to such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         The  aggregate  amount of  consideration  required by ICP3 and ICPI3 to
purchase  the Shares to which this  statement  relates  was  approximately  $2.0
million.  The  consideration  was obtained from the working  capital of ICP3 and
ICPI3.

ITEM 4.  PURPOSE OF TRANSACTION

         The  purchases  of the  Shares  were  made  pursuant  to a  Convertible
Preferred Stock Purchase  Agreement,  dated as of August 28, 1997 (the "Purchase
Agreement"). Pursuant to the Purchase Agreement, ICP3 and ICPI3 purchased 81,550
shares and 18,450 shares of Series D Convertible Preferred Stock,  respectively,
and  warrants to purchase an aggregate  of 190,282  shares and 43,050  shares of
Common  Stock,  respectively.  The purchases of the Shares were not made for the
purpose of acquiring control of the Issuer.  From time to time, ICM3 may, in the
ordinary  course  of its role as  general  partner  of ICP3  and the  investment
general partner of ICPI3, direct ICP3 and/or ICPI3 to purchase additional shares
or sell all or a portion of the Shares now held by ICP3 or ICPI3.

         Except  as set  forth  above,  none of ICM3 nor the  persons  listed on
Exhibit B hereto has any  current  plans or  proposals  that  relate to or would
result in the  occurrence  of any of the actions or events  enumerated in clause
(a) through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

     A.  Integral Capital Management III, L.P. ("ICM3")

         (a) ICM3 may be  deemed  the  beneficial  owners  of  1,152,872  Shares
(approximately 5.78% of the total number of shares of Common Stock outstanding).
This number  includes (A) an aggregate of 100,000 shares of Series D Convertible
Preferred  Stock held by ICP3 and ICPI3 and (b) warrants  held by ICP3 and ICPI3
to purchase an aggregate of 233,332 shares of Common Stock.  ICM3 is the general
partner of ICP3 and the  investment  general  partner of ICPI3,  and as such has
voting and dispositive power of the Shares. Each share of the Series D Preferred
Stock is convertible into shares of Common Stock of the Issuer from time to time
at a rate  determined  by the lesser of (a) the lower of (1) the average  quoted
market price of the Common Stock for the ten trading days  preceding the date of
issuance and (2) the lower of (x) the average  quoted market price of the Common
Stock for the ten trading  days  immediately  preceding  any  issuance of Common
Stock (or Common Stock equivalents) by the Issuer prior to November 26, 1997 and
(y) the  price at which  the  Common  Stock is so  issued  or may be  issued  on
conversion  or  exercise  of the  Common  Stock  equivalent,  and (b) the lowest
average  quoted  market  prices for any five  trading  days during the period of
thirty  days  before the  conversion.  The amount of Common  Stock shown in this
Schedule  13D  reflects  the  amount  into  which  the full  amount  of Series D
Preferred  Stock might have been converted on August 28, 1997 in accordance with
the market-price formula. Because the number of shares of Common Stock that will
be

                                                                    Page 7 of 38

ultimately  issued to ICP3 and ICPI3 upon  conversion  of the Series D Preferred
Stock is dependent  upon the conversion  formula  described  above,  that amount
cannot be  determined at this time but will  determined  upon the date of actual
conversion based on the above rate.

         (b) Number of shares as to which such person has:
             1. Sole power to vote or to direct vote: -0-
             2. Shared power to vote or to direct vote:  1,152,872
             3. Sole power to dispose or to direct the disposition:   -0-
             4. Shared power to dispose or to direct the disposition: 1,152,872

         (c) To the best knowledge of ICM3, none of ICP3,  ICPI3,  ICM3, nor any
of the  persons  listed as general  partners  of ICM3 on Exhibit B has  directly
effected any transactions in shares of capital stock of the Issuer during the 60
days prior to the date  hereof,  other than the  purchase  of shares of Series D
Preferred Stock and Warrant Stock pursuant to the Purchase Agreement.

         (d) ICM3 is the general partner of Integral Capital Partners III, L.P.,
a Delaware limited partnership  ("ICP3"),  and the investment general partner of
Integral  Capital  Partners  International  III, L.P., a Cayman Islands exempted
limited partnership  ("ICPI3").  Roger B. McNamee,  John A. Powell and Pamela K.
Hagenah are the general partners of ICM3. Decisions respecting the voting of the
Series D Preferred  Stock and  disposition  of the proceeds from the sale of the
Shares are  determined  by a majority of the  general  partners.  Under  certain
circumstances set forth in the limited partnership agreements of ICP3, ICPI3 and
ICM3,  the general and limited  partners of such entities may receive  dividends
from, or the proceeds  from the sale of Shares of the Issuer owned,  directly or
indirectly, by each such entity.

         (e) Not applicable.


   B.    Integral Capital Partners III, L.P.

         (a) ICP3 is the beneficial owner of 940,167 Shares (approximately 4.76%
of the total number of shares of Common Stock outstanding). This number includes
(A) 81,550 shares of Series D Convertible  Preferred Stock and (b) warrants held
to purchase an aggregate of 190,282  shares of Common  Stock.  Each share of the
Series D  Preferred  Stock is  convertible  into  shares of Common  Stock of the
Issuer from time to time at a rate determined by the lower of the average quoted
market price of the Common  Stock for either (i) the ten trading days  preceding
the date of issuance or (ii) any five  trading  days during the period of thirty
days before the  conversion.  The amount of Common Stock shown in this  Schedule
13D reflects  the amount into which the full amount of Series D Preferred  Stock
might have been converted on August 28, 1997 in accordance with the market-price
formula.  Because the number of shares of Common  Stock that will be  ultimately
issued to ICP3 upon conversion of the Series D Preferred Stock is dependent upon
the conversion formula described above, that amount cannot be determined at this
time but will determined upon the date of actual  conversion  based on the above
rate.

         (a) ICPI3 is the  beneficial  owner of  212,705  Shares  (approximately
1.12% of the total  number of shares of Common Stock  outstanding).  This number
includes  (A)  18,450  shares of Series D  Convertible  Preferred  Stock and (b)
warrants held to purchase an aggregate of 43,050  shares of Common  Stock.  Each
share of the Series D Preferred Stock is convertible into shares of Common Stock
of the Issuer from time to time at a rate determined by the lower of the average
quoted  market  price of the Common  Stock for either (i) the ten  trading  days
preceding  the date of issuance or (ii) any five  trading days during the period
of thirty days before the  conversion.  The amount of Common Stock shown in this
Schedule  13D  reflects  the  amount  into  which  the full  amount  of Series D
Preferred  Stock might have been converted on August 28, 1997 in accordance with
the market-price formula. Because the number of shares of Common Stock that will
be ultimately issued to ICPI3 upon conversion of the Series D Preferred Stock is

determined at this time but will determined  upon the date of actual  conversion
based on the above rate.

              2.  Shared power to vote or to direct vote: 212,705

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS, OR
         RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE
         ISSUER

         Except  as set forth  herein,  there  are no  contracts,  arrangements,
understandings or relationships  among ICM3 and any of the persons named in Item
2 or between  ICM3 and any other person with respect to the Shares of the Issuer
held by ICP3 and ICPI3.  The purchases of the Shares by ICP3 and ICPI3 were made

         Pursuant to the terms of the Purchase Agreement,  ICP3 and ICPI3 agreed
not to sell of otherwise dispose of the Shares purchased  thereunder except in a

exemption from such registration is available.

         Pursuant to Section 4.12 of the Purchase Agreement, ICP3 and ICPI3 have

hereby represents and warrants to the Purchaser as follows:

         (a) Organization and Qualification.  The Company is a corporation, duly
incorporated,  validly  existing  and in good  standing  under  the  laws of The

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,  have a material adverse effect on
the results of  operations,  assets,  prospects,  or financial  condition of the
Company and the Subsidiaries, taken as a whole (a "Material Adverse Effect").

         (b) Authorization; Enforcement. The Company has the requisite corporate
power  and  authority  to  enter  into  and  to  consummate   the   transactions

Preferences and by the Registration Rights Agreement, and otherwise to carry out
its obligations  hereunder and  thereunder.  This  Agreement,  the  Registration
Rights Agreement,  the Statements of Rights and Preferences and the Warrants are

delivery 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.  Each of the Transaction  Documents
has been duly executed and delivered by the Company and  constitutes  the legal,
valid and binding obligation of the Company  enforceable  against the Company in
accordance  with its  terms,  except as such  enforceability  may be  limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium, liquidation or
similar laws relating to, or affecting  generally the enforcement of, creditors'
rights and remedies or by other  equitable  principles  of general  application.
Neither the Company nor any  Subsidiary is in violation of any of the provisions

stock of the  Company  and each of the  Subsidiaries  is set  forth in  Schedule

options,  warrants,  script rights to subscribe to, calls or  commitments of any
character  whatsoever  relating  to, or,  except as a result of the purchase and
sale of the Shares and Warrants  hereunder,  securities,  rights or  obligations
convertible  into or  exchangeable  for,  or  giving  any  person  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 Shares, Warrants, Warrant Shares and Underlying Shares.
The Shares and the Warrants are duly authorized and, when paid for in accordance
with the terms hereof,  shall be validly issued,  fully paid and  nonassessable,
free and clear of any Liens.  The Company,  as at the Closing Date will have and
at all times while the Shares and any Warrants are outstanding  will maintain an
adequate  reserve  of  shares  of  Common  Stock to  enable  it to  perform  its
conversion  and other  obligations  under this  Agreement,  the Warrants and the
Statements  of Rights and  Preferences  with respect to the number of Shares and
Warrants issued and outstanding at such Closing Date,  which reserve shall be no
less  than the sum of (i) the  greater  of (x) 125% of the  number  of shares of
Common  Stock  issuable  upon  conversion  of all the Series D  Preferred  Stock
outstanding  from time to time or (y) twice the number of shares of Common Stock
issuable  hereunder  and pursuant to the terms of the  Statements  of Rights and
Preferences,  assuming a conversion in full of all of the Shares on the Original
Issue Date thereof and (ii) the number of shares of Common Stock  issuable  upon
the exercise in full of the Warrants (the "Warrant Shares") to be issued at such
Closing Date. When issued in accordance with the terms hereof and the Statements

Warrant  Shares  will  be  duly  authorized,  validly  issued,  fully  paid  and
nonassessable, free and clear of all Liens.

Company and its  consolidated  subsidiaries  as of and for the dates thereof and
the results of operations and cash flows for the periods then ended, subject, in

         (r) Intellectual  Property Rights. The Company and its subsidiaries own
or possess  adequate  rights or licenses  to use all  trademarks,  trade  names,

         (s) 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 which is material to the business of the Company
and its Subsidiaries, in each case free and clear of all liens, encumbrances and
defects except 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.  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

with  this  Agreement  and the  Statement  of  Rights  and  Preferences  and its
obligation  to issue  the  Warrant  Shares  upon  exercise  of the  Warrants  in
accordance with this Agreement and the Warrants,  is, in each case, absolute and
unconditional  regardless of the dilutive  effect that such issuance may have on
the ownership interests of other stockholders of the Company.

         Section 3.2.  Representations  and Warranties of the  Purchasers.  Each
Purchaser hereby severally represents and warrants to the Company as follows:

         (a)   Organization;   Authority.   The  Purchaser  is  a   corporation,
partnership,  limited  liability  company,  or other  entity  duly  and  validly
existing  and in  good  standing  under  the  laws  of the  jurisdiction  of its
organization.  The Purchaser has the requisite power and authority to enter into
and to  consummate  the  transactions  contemplated  hereby  and  by  the  other
Transaction  Documents and otherwise to carry out its obligations  hereunder and
thereunder.  The  purchase  of the  Shares  and the  Warrants  by the  Purchaser
hereunder has been duly  authorized  by all necessary  action on the part of the
Purchaser.  Each  of the  Transaction  Documents  has  been  duly  executed  and
delivered  by the  Purchaser  or on its  behalf  and  constitutes  the valid and
legally binding obligation of the Purchaser,  enforceable  against the Purchaser
in accordance  with its terms,  subject to  bankruptcy,  insolvency,  fraudulent
transfer,  reorganization,  moratorium and similar laws of general applicability
relating to or affecting  creditors' rights generally and to general  principles
of equity.

         (b)  Investment  Intent.  The  Purchaser is acquiring  the Shares,  the
Warrants,  the Warrant Shares and the Underlying  Shares for its own account for
investment purposes only and not with a view to or for distributing or reselling
such Shares,  Warrants,  Warrant Shares or Underlying Shares or any part thereof
or interest  therein,  without  prejudice,  however,  to the Purchaser's  right,
subject to the provisions of the Transaction Documents,  at all times to sell or
otherwise dispose of all or any part of such Shares, Warrants, Warrant Shares or
Underlying Shares under an effective registration statement under the Securities
Act  and in  compliance  with  applicable  state  securities  laws or  under  an
exemption from such registration.

         (c) Purchaser  Status.  The Purchaser was not formed for the purpose of
acquiring the Shares and the Warrants. At the time the Purchaser was offered the
Shares  and the  Warrants,  it was and at the date  hereof it is an  "accredited
investor" as defined in Rule 501(a) under the Securities Act.

         (d)  Experience  of  Purchaser.   The  Purchaser  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
Shares,  the Warrants,  the Underlying Shares and the Warrant Shares, and has so
evaluated the merits and risks of such investment.

         (e) Ability of Purchaser to Bear Risk of  Investment.  The Purchaser is
able to bear the economic risk of an investment in the Shares, the Warrants, the
Underlying  Shares and the Warrant  Shares and is able to afford a complete loss
of such investment.

         (f) Prohibited Transactions.  The Shares and the Warrants are not being
acquired,  directly  or  indirectly,  with the assets of any  "employee  benefit
plan",  within the meaning of Section  3(3) of the  Employee  Retirement  Income
Security Act of 1974, as amended.

         (g) Access to Information.  The Purchaser  acknowledges  receipt of the
Disclosure  Materials and further acknowledges that it 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  Shares  and the  Warrants  and the merits and risks of
investing in the Shares and the Warrants;  (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 in the Company;  and (iii) the  opportunity to obtain such additional
information  that the  Company  possesses  or can acquire  without  unreasonable
effort or expense and that is necessary to make an informed  investment decision
with  respect to the  Shares and the  Warrants  and to verify the  accuracy  and
completeness of the information contained in the Disclosure Materials.

         (h) Reliance.  The Purchaser  understands and acknowledges that (i) the
Shares and the Warrants are being offered and sold,  and the  Underlying  Shares
and the Warrant Shares are being offered,  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 that the  Company  will  rely  upon the  accuracy  and
truthfulness of, the foregoing representations and the Purchaser hereby consents
to such reliance.

         The  Company  acknowledges  and  agrees  that  the  Purchaser  makes no
representation or warranty with respect to the transactions  contemplated hereby
other than those specifically set forth in this Section 3.2.

                         OTHER AGREEMENTS OF THE PARTIES

         Section 4.1. Transfer  Restrictions.  If the Purchaser should decide to
dispose of any of the Shares or any portion of the Warrants (and upon conversion
or exercise  thereof,  any Underlying  Shares or Warrant Shares),  the Purchaser
understands  and agrees that it may do so only (i) pursuant to an effective  the
registration  statement  under the Securities Act, (ii) pursuant to an available
exemption from the  registration  requirements of the Securities Act or (iii) to
the Company. In connection with any transfer of any Shares, Warrants, Underlying
Shares or  Warrant  Shares  other than  pursuant  to an  effective  registration
statement or to the Company, the Company may require that the transferor provide
to the Company an opinion of counsel  experienced  in the area of United  States
securities  laws  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 Shares,  Warrants,  Underlying
Shares or Warrant Shares under the Securities Act or any state securities laws.

         The Purchaser agrees to the imprinting,  so long as is required by this
Section,  of the  following  legend on  certificates  representing  the  Shares,
Warrants, Underlying Shares or Warrant Shares:

         NEITHER THESE SECURITIES NOR ANY SECURITIES INTO WHICH THESE SECURITIES
MAY BE [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  PROMULGATED 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 LAW.

         The legend set forth  above  shall be removed  upon the  conversion  of
Shares or exercise  of Warrants  represented  by such  certificates  at any time
while an Underlying  Securities  Registration  Statement is effective  under the
Securities  Act or  sooner  if,  in  the  opinion  of  counsel  to  the  Company
experienced  in the area of United  States  securities  laws  such  legend is no
longer required under  applicable  requirements of the Securities Act (including
judicial   interpretations  and  pronouncements  issued  by  the  staff  of  the
Commission).  The  Company  agrees  that it will  provide  the  Purchaser,  upon
request,  with  a  substitute  stock  certificate  or  certificates  or  warrant
certificates,  free  from such  legend at such time as such  legend is no longer
applicable.

         Section 4.2.  Stop Transfer  Instruction.  The Company may not make any
notation  on its  records  or give  instructions  to any  transfer  agent of the
Company which enlarge the

restrictions  on  transfer  set  forth  in  Section  4.1  above,  or  which  are
inconsistent with the instructions stated in Exhibit D.

         Section 4.3.  Furnishing of  Information.  For so long as the Purchaser
owns  Shares,  Warrants,  Underlying  Shares  or  Warrant  Shares,  the  Company
covenants to timely file (or obtain  valid  extensions  in respect  thereof) 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 and to promptly furnish the Purchaser
with true and complete copies of all such filings.  If the Company is not at the
time  required to file reports  pursuant to such  sections,  it will prepare and
furnish to the Purchaser  annual and quarterly  financial  statements,  together
with a  discussion  and  analysis  of such  financial  statements  in  form  and
substance  substantially similar to those that would otherwise be required to be
included in reports  required by Section  13(a) or 15(d) of the  Exchange Act in
the time period  that such  filings  would have been  required to have been made
under the Exchange Act.

         Section 4.4. Notice of Certain Events. The Company shall (i) advise the
Purchaser promptly after obtaining  knowledge thereof,  and, if requested by the
Purchaser,  confirm  such  advice in writing,  of (A) the  issuance by any state
securities  commission  of  any  stop  order  suspending  the  qualification  or
exemption from qualification of the Shares,  Warrant Shares or Underlying Shares
or the Common Stock for offering or sale in any jurisdiction,  or the initiation
of any proceeding for such purpose by any state  securities  commission or other
regulatory  authority,  or (B) any event that makes any  statement of a material
fact made in the Disclosure  Materials untrue or that requires the making of any
additions  to or  changes  in the  Disclosure  Materials  in  order  to make the
statements therein, in the light of the circumstances under which they are made,
not misleading,  provided,  however,  that the Company shall not give any notice
before the facts disclosed in the notice have been publicly disclosed,  (ii) use
its best efforts to prevent the  issuance of any stop order or order  suspending
the qualification or exemption from qualification of the Shares,  Warrant Shares
or Underlying  Shares or the Common Stock under any state securities or Blue Sky
laws,  and  (iii)  if at any  time  any  state  securities  commission  or other
regulatory  authority  shall  issue an order  suspending  the  qualification  or
exemption from qualification of the Shares,  Warrant Shares or Underlying Shares
or the  Common  Stock  under any such laws,  use its best  efforts to obtain the
withdrawal or lifting of such order at the earliest possible time.

         Section 4.5. Copies and Use of Disclosure Materials.  The Company shall
furnish  the  Purchaser,  without  charge,  as  many  copies  of the  Disclosure
Materials,  and any  amendments  or  supplements  thereto,  as the Purchaser may
reasonably request. The Company consents to the use of the Disclosure Materials,
and any amendments and supplements  thereto, by the Purchaser in connection with
resales of the Shares,  the Warrant Shares or the  Underlying  Shares other than
pursuant to an effective registration statement.

         Section 4.6. Modification to Disclosure  Materials.  If any event shall
occur as a result  of which,  in the  reasonable  judgment  of the  Company,  it
becomes  necessary or advisable to amend or supplement the Disclosure  Materials
in order to make the statements  therein,  in the light of the  circumstances at
the  time  the  Disclosure  Materials  were  delivered  to  the  Purchaser,

not  misleading,  or if it is necessary to amend or  supplement  the  Disclosure
Materials to comply with applicable  law, the Company shall promptly  prepare an
appropriate  amendment or supplement to the Disclosure  Materials so that (i) as
so amended or supplemented  the Disclosure  Materials will not include an untrue
statement of material fact or omit to state a material  fact  necessary in order
to make the statements  therein,  in the light of the circumstances  existing at
the time it is delivered to Purchaser,  not  misleading  and (ii) the Disclosure
Materials will comply in all material respects with applicable law.

         Section 4.7. Blue Sky Laws. In accordance with the Registration  Rights
Agreement,  the Company  shall  qualify the Shares,  the  Warrants,  the Warrant
Shares and the  Underlying  Shares under the securities or Blue Sky laws of such
jurisdictions  as the  Purchaser  may  reasonably  request and to continue  such
qualification  at all times through the third  anniversary  of the Closing Date;
provided,  however,  that  neither  the Company  nor its  Subsidiaries  shall be
required in connection  therewith to qualify as a foreign corporation where they
are not now so qualified.

         Section 4.8. Integration.  The Company shall not and shall use its best
efforts to ensure that no Affiliate 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
Shares,  the  Warrant  Shares or the  Underlying  Shares in a manner  that would
require the registration under the Securities Act of the sale of the Shares, the
Warrant Shares or Underlying Shares to the Purchaser.

         Section 4.9. Furnishing of Rule 144A Materials.  The Company shall, for
so long as any of the Shares,  Warrants,  Warrant  Shares or  Underlying  Shares
remain  outstanding  and during any period in which it is not subject to Section
13 or 15(d) of the Exchange  Act,  make  available to any  registered  holder of
Shares  or  Underlying  Shares  in  connection  with  any sale  thereof  and any
prospective  purchaser of such Shares,  Warrants,  Warrant  Shares or Underlying
Shares from such Person,  the  following  information  in  accordance  with Rule
144A(d)(4)  under the  Securities  Act: a brief  statement  of the nature of the
business  of the  Company  and the  products  and  services  it  offers  and the
Company's  most recent  audited  balance  sheet and profit and loss and retained
earnings  statements,  and similar audited financial statements for such part of
the two preceding fiscal years as the Company has been in operation.

         Section  4.10.  Solicitation  Materials.  The  Company  shall  not  (i)
distribute  any offering  materials in connection  with the offering and sale of
the  Shares,  Warrants,  Warrant  Shares or  Underlying  Shares  other  than the
Disclosure  Materials and any amendments  and  supplements  thereto  prepared in
compliance  herewith  or (ii)  solicit  any  offer  to buy or sell  the  Shares,
Warrants,  Warrant  Shares or Underlying  Shares by means of any form of general
solicitation or advertising.

         Section  4.11.  Subsequent  Financial  Statements.  The  Company  shall

by the financial statements included in the Disclosure Materials.

         Section 4.12. Right of First Refusal;  Certain Corporate  Actions.  (a)
The Company shall not, directly or indirectly, without the prior written consent
of the Purchaser, offer, sell, grant any option to purchase or otherwise dispose
(or  announce  any  offer,  sale,  grant  or any  option  to  purchase  or other

repurchase or otherwise  acquire shares of its Junior  Securities (as defined in
the Statements of Rights and Preferences); or (iv) enter into any agreement with
respect to any of the foregoing.

         Section  4.13.  Notwithstanding  anything  to  the  contrary  contained
herein, each Conversion Notice shall contain a representation that, after giving
effect to the shares of the Company's Common Stock to be issued pursuant to such
Conversion  Notice,  the total  number of shares of the  Company's  Common Stock
deemed beneficially owned by the holder thereof, together with all shares of the
Company's Common Stock deemed  beneficially owned by such holder's  "affiliates"
as defined in Rule 144 promulgated under the Securities Act of 1933, as amended,
(exclusive of shares issuable upon conversion of the unconverted  portion of the
Shares of Series D Preferred Stock or the unexercised or unconverted  portion of
any other  securities  of the Company  subject to a limitation  on conversion or
exercise  analogous  to the  limitations  contained  herein)  will not result in
beneficial  ownership by the holder and its  affiliates of more than 4.9% of the
outstanding   shares  of  Common  Stock.  For  purposes  of  this  subparagraph,
beneficial ownership shall be determined in accordance with Section 13(d) of the
Securities  Exchange Act of 1934, as amended,  and Regulation 13 D-G thereunder,
except as other provided  above.  Any  Conversion  Notice which does not contain
such representation shall be ineffective provided, however, that the requirement
of this  paragraph  shall not apply to any  Purchaser  marked as "excluded  from
Section 4.13" on Schedule A.

         Section  4.14.  Availability  of Common  Stock.  The  Company  has duly
reserved a sum of 5,200,000  shares of authorized and unissued  Common Stock for
issuance  upon the  conversion  of Series D Shares and the  exercise  all of the
Series D Warrants.  If at any time the Company does not have reserved sufficient
shares of Common  Stock to enable it to  perform  its  conversion  and  exercise
obligations  hereunder  with  respect to all shares of  Preferred  Stock and all
Warrants then  outstanding  it shall,  at the option of the holders of Preferred

the Nasdaq  National  Market or  SmallCap  Market,  as the case may be (and each
other national securities exchange on which the Common Stock is then listed) for
the listing of the Underlying Shares and the Warrant Shares.  The Company shall,
as promptly as possible, take all steps necessary to cause the Underlying Shares
and Warrant Shares to be approved for listing in the Nasdaq  National  Market or
SmallCap Market (and each other national  securities exchange or market on which
the Common Stock is then listed), and shall provide to the Purchaser evidence of
such listing when approved and shall maintain the listing of its Common Stock on
such exchange.

National  Market  (other  than as a  result  of the  suspension  of  trading  in
securities on such market or exchange generally or temporary suspensions pending
the release of material  information  and other than a suspension  of trading on
the Nasdaq  National  Market if the Common Stock is listed for trading,  and not
suspended, on the Nasdaq SmallCap Market within

one  Business  Day  after  such  suspension)  for  more  than ten  days,  at the
Purchaser's  option  exercisable by written  notice to the Company,  the Company
shall  redeem for cash all Shares and all  Underlying  Shares  then held by such
Purchaser,  at an  aggregate  purchase  price  equal to (A) the  product  of the
average Per Share Market Value for the five Trading Days  immediately  preceding
the day of such notice  multiplied  by the number of shares of Common Stock into
which the Shares to be purchased are then convertible and exercisable (or in the
case of Underlying  Shares,  the number of Underlying  Shares to be  purchased),
plus (B) interest on such amount  accruing from the 7th day after such notice at
the rate of 15% per annum.

         Section  4.17.  No Violation of  Applicable  Law.  Notwithstanding  any
provision of this  Agreement to the  contrary,  if any  redemption  of Shares or
Underlying  Shares  otherwise  required under the  Transaction  Documents or the
Statements  of  Rights  and  Preferences  would be  prohibited  by the  relevant
provisions of the Massachusetts  Business Corporation Law, such redemption shall
be effected as soon as it is permitted under such law; provided,  however, that,
interest  payable  by the  Company  with  respect to any such  redemption  shall
continue to accrue in accordance with Section 4.16 during any such period.

         Section 4.18. Redemption Restrictions. Notwithstanding any provision of
this Agreement to the contrary, if any redemption of Shares or Underlying Shares
otherwise  required under this  Agreement  would be prohibited in the absence of
consent from any lender of the Company or of any  Subsidiary,  or by the holders
of any  class of  securities  of the  Company,  the  Company  shall use its best
efforts to obtain such consent as promptly as  practicable  after the redemption
is required but in no event later than 30 days after the redemption is required.
Interest  payable  by the  Company  with  respect to any such  redemption  shall
continue  to accrue in  accordance  with  Section  4.16  until  such  consent is
obtained.  Nothing  contained in this Section  shall be construed as a waiver by
the  Purchaser  of any  rights  it may  have  by  virtue  of any  breach  of any
representation  or  warranty  of the  Company  herein as to the  absence  of any
requirement to obtain any such consent.

         Section 4.19. Notice of Breaches. Each of the Company and the Purchaser
shall  give  prompt   written   notice  to  the  other  of  any  breach  of  any
representation,  warranty  or  other  agreement  contained  in  the  Transaction
Documents,  as well as any events or  occurrences  arising after the date hereof
and prior to the Closing  Date,  which could  reasonably  be likely to cause any
representation or warranty or other agreement of such party, as the case may be,
contained herein or therein to be incorrect or breached as of such Closing Date.
However,  no disclosure by either party pursuant to this Section shall be deemed
to cure any breach of any representation,  warranty or other agreement contained
herein  or  in  the  other  Transaction  Documents.  Neither  the  Company,  any
Subsidiary  nor the Purchaser  will take, or agree to commit to take, any action
that is  intended to make any  representation  or warranty of the Company or the
Purchaser,  as the case may be,  contained  herein or in the  other  Transaction
Documents  or in the  Statements  of Rights and  Preferences  inaccurate  in any
respect at such Closing Date.

     Notwithstanding the generality of the foregoing, the Company shall promptly
notify the  Purchaser of any notice or claim  (written or oral) that it receives
from any  lender of the  Company  to the  effect  that the  consummation  of the
transactions contemplated by the Transaction

Documents  violates  or would  violate any written  agreement  or  understanding
between such lender and the Company,  and the Company shall promptly  furnish by
facsimile  to the  holders  of the Shares  and  Warrants  a copy of any  written
statement in support of or relating to such claim or notice.

         Section 4.20. The Warrants.

         (a) The Series D Warrants.  At the Series D Closing,  the Company shall

equal to 125% of the average  Per Share  Market  Value for the ten trading  days
immediately  preceding the Closing Date (the "Average Price") in accordance with
the terms thereof and shall be exercisable  through the date that is three years
after the Closing Date, (ii) one Series D Warrant shall entitle the Purchaser to
acquire  0.66666 shares of Common Stock for each share of Preferred  Stock being
purchased  by that  Purchaser  at a price per share equal to 135% of the Average

date that is four years after the Closing  Date,  and (iii) one Series D Warrant
shall  entitle the Purchaser to acquire 1.0 share of Common Stock for each share
of Preferred  Stock being purchased by that Purchaser at a price per share equal
to 150% of the Average Price in  accordance  with the terms thereof and shall be
exercisable through the date that is five years after the Closing Date.

         (b) The Warrants shall be substantially in the form of Exhibit E.

omission of either  party to exercise any right  hereunder in any manner  impair
the exercise of any such right accruing to it thereafter.

         Section 5.5. Headings. The headings herein are for convenience only, do
not  constitute  a part of this  Agreement  and  shall not be deemed to limit or

securities  or transfer or assign  rights  hereunder  or under the  Registration

Company  and the  Purchaser  contained  in Article  III and the  agreements  and

conversion of Shares and exercise of Warrants hereunder.

         Section 5.10. Counterpart Signatures. This Agreement may be executed in
two or more  counterparts,  all of which when taken together shall be considered
one and the same  agreement and shall become  effective when  counterparts  have
been signed by each party and 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.

         Section 5.11.  Publicity.  The Company and the Purchaser  shall consult
with each  other in  issuing  any press  releases  or  otherwise  making  public
statements  with  respect to the  transactions  contemplated  hereby and neither
party  shall  issue any such press  release or  otherwise  make any such  public
statement  without the prior written  consent of the other,  which consent shall
not be 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.

         Section 5.12.  Severability.  In case any one or more of the provisions
of this Agreement shall be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement shall
not in any way be affected or impaired  thereby and the parties  will attempt to
agree  upon a valid  and  enforceable  provision  which  shall  be a  reasonable
substitute  therefor,  and upon so agreeing,  shall  incorporate such substitute
provision in this Agreement.

         Section 5.13.  Remedies.  In addition to being entitled to exercise all
rights provided  herein or granted by law,  including  recovery of damages,  the
Purchaser  will be entitled to specific  performance  of the  obligations of the
Company under this Agreement and the other Transaction Documents and the Company
will be entitled to specific  performance  of the  obligations  of the Purchaser
hereunder with respect to the subsequent transfer of Shares,  Warrants,  Warrant
Shares and Underlying Shares.  Each of the Company and the Purchaser agrees that
monetary  damages  would not be adequate  compensation  for any loss incurred by
reason of any breach of its obligations  described in the foregoing sentence and
hereby  agrees  to waive in any  action  for  specific  performance  of any such
obligation the defense that a remedy at law would be adequate.
