                  3.15  Title to Properties; Liens and Encumbrances.

                        (i)   Except as disclosed on Schedule  3.15, the Company
has good and  marketable  title to its assets,  including,  without  limitation,
those  reflected on the September 30, 1999 balance sheet (other than those since
disposed of in the ordinary course of business),  free and clear of all security
interests, liens, charges and other encumbrances, except for (i) liens for taxes
not yet due and  payable  or  being  contested  in  good  faith  in  appropriate
proceedings,  and (ii)  encumbrances that are incidental to the conduct of their
respective businesses or ownership of property,  not incurred in connection with
the  borrowing  of money or the  obtaining  of  credit,  and which do not in the
aggregate materially detract from the value of the assets affected or materially
impair their use by the Company.  With respect to the assets of the Company that
are leased, the




                                      5





Company is in  compliance  with all  material  provisions  of such  leases.  All
facilities, machinery, equipment, fixtures, vehicles and other properties owned,
leased or used by the Company are in good operating condition and repair, normal
wear and tear  excepted,  and are  adequate  and  sufficient  for the  Company's
business.

                        (ii)  The  Company  enjoys   peaceful  and   undisturbed
possession  under all real property leases under which the Company is operating,
and all such leases are valid and subsisting and none of them is in default.

                  3.16  Patents, Trademarks and Other Intangible Assets.

                        (i)   Schedule  3.16  hereto  sets  forth  the  true and
correct  list  of  all  registered   patents,   trademarks  and  copyrights  (or
applications  therefor)  held by the  Company.  Except as set forth on  Schedule
3.16,  the  Company  possesses  ownership  or has the right to use all  patents,
copyrights,  trademarks,  service  marks,  trade  secrets and other  proprietary
intellectual  property rights necessary for the operation of its business except
where  the  failure  of the  Company  to own or  have  such  right  to use  such
intellectual  property  would not have a material  adverse effect on the Company
(the "Intellectual  Property").  To the Company's knowledge,  the Company (a) is
not infringing  upon the  intellectual  property  rights of others in connection
with its business;  (b) does not require the consent of any person which has not
been  obtained to use the  Intellectual  Property;  or (c) has not  received any
written notice of conflict with respect to the  intellectual  property rights of
any other  person  or  entity.  All of the  Intellectual  Property  is valid and
subsisting,  has not been canceled,  abandoned or otherwise  terminated  and, if
applicable,  has been duly issued or filed. The employees and consultants of the
Company,  who,  either  alone or in concert with  others,  developed,  invested,
discovered,   derived,  programmed  or  designed  any  of  the  Company's  owned
Intellectual  Property  have  entered  into  written  agreements  to protect the
confidentiality  of the Company's owned  Intellectual  Property and to assign to
the Company all rights therein.

                        (ii) The Company has no knowledge of any claim that, or
inquiry as to  whether,  any  product,  activity  or  operation  of the  Company
infringes  upon  or  involves,  or has  resulted  in the  infringement  of,  any
proprietary  right of any other  person,  corporation  or other  entity;  and no
proceedings have been  instituted,  are pending or are threatened that challenge
the rights of the Company with respect thereto.

                  3.17  Trade  Secrets and  Customer  Lists. The Company has the
right to use,  free and  clear of any  claims  or  rights  of  others  all trade
secrets,  customer lists and proprietary  information required for the marketing
of all  merchandise  and services  formerly or presently sold or marketed by the
Company. To the Company's  knowledge,  it is not using, or in any way making use
of, any confidential information or trade secrets of any third party, including,
without limitation, any past or present employee of the Company.

                  3.18  Tax Matters.

                        (i)   All required foreign,  federal,  state,  local and
other tax returns, notices and reports (including,  without limitation,  income,
property, sales, use, franchise,  capital stock, excise, added value, employees'
income withholding, social security and unemployment tax returns) of the Company
have been  accurately  prepared  in all  material  respects  and duly and timely
filed,  and all foreign,  federal,  state,  local and other taxes required to be
paid with respect to the periods  covered by such  returns  have been paid.  The
Company is not and has not been delinquent in the payment of any tax, assessment
or governmental  charge. The Company is not a party to any agreement,  contract,
arrangement  or plan that has  resulted or would  result,  separately  or in the
aggregate,  in the payment of any "excess parachute payments" within the meaning
of  Section  280G of the  Code.  The  Company  does  not  have and has not had a
permanent establishment in any foreign country, as defined in any applicable tax
treaty or convention between the United States and such foreign country.

                        (ii)  The  Company  has  not  had  any  tax   deficiency
proposed or assessed  against it and has not  executed any waiver of any statute
of  limitations  on the  assessment  or  collection  of any tax or  governmental
charge.  None of the Company's tax returns has ever been audited by governmental
authorities.  No tax audit, action, suit, proceeding,  investigation or claim is
now pending nor, to the best  knowledge of the Company,  threatened  against the
Company,  and no issue or question has been raised (and is currently pending) by
any taxing  authority in  connection  with any of the  Company's  tax returns or
reports.

                        (iii) To  the  Company's  knowledge,  the  reserves  for
taxes,  assessments and governmental  charges reflected on the Balance Sheet are
and will be  sufficient  for the  payment of all unpaid  taxes and  governmental
charges  payable by the Company  with respect to the period ended on the Balance
Sheet  Date.  Since the  Balance  Sheet  Date,  the  Company  has made  adequate
provisions on its books of account for all taxes,  assessments and  governmental
charges with respect to business, properties and operations for such period. The
Company  withheld or  collected  from each payment  made to its  employees,  the
amount of all taxes  (including,  but not  limited  to,  federal  income  taxes,
Federal Insurance Contribution Act taxes and Federal Unemployment Tax Act taxes)
required  to be withheld or  collected  therefrom,  and has paid the same to the
proper tax receiving officers or authorized depositories.

                  3.19  Litigation.  No action,  proceeding or  investigation is
pending or threatened  against the Company,  or any of its properties before any
court,  arbitration board or tribunal or  administrative  or other  governmental
agency (including,  without limitation, unfair labor practices or discrimination
charges  or  complaints),  that  might  result,  either  individually  or in the
aggregate, in any material adverse change in the business, prospects, condition,
affairs,  operations,  or assets of the Company or in any material  liability on
the  part  of  the  Company.  The  foregoing  includes,   without  limiting  its
generality,  actions pending or threatened involving the prior employment of any
of the Company's employees or use by any of them in connection with the




                                      7






Company's  business  of  any  information,   property  or  techniques  allegedly
proprietary to any of their former employers.

                  3.20  Insurance.  The  Company  carries  property,  liability,
workers'  compensation  and such other types of insurance as is customary in the
Company's industry. A list of all insurance policies of the Company is set forth
in Schedule  3.20.  All of such  policies  are valid and  enforceable  policies,
issued by  insurers of  recognized  responsibility  in amounts and against  such
risks and  losses as are  customary  in the  Company's  industry.  All  casualty
insurance  is  sufficient  in amount to allow the  Company to replace any of its
properties that might be damaged or destroyed.

                  3.21  Employee Benefit Plans.

                        (i)   Schedule 3.21 contains a true and complete list of
any bonus,  incentive,  insurance  (including  any  self-insured  arrangements),
compensation plan, welfare, retirement, defined benefit, 401(k), pension, profit
sharing, salary reduction, deferred compensation,  stock purchase, stock option,
workers' compensation,  disability benefits,  supplemental unemployment benefits
(including without limitation any "voluntary employees' beneficiary association"
as defined in Section 501(C)(9) of the Code) (as hereinafter defined), vacation,
holiday and sick pay or other similar  benefit plans,  programs or  arrangements
(whether written or oral) (said plans,  programs or arrangements  being referred
to as the  "Plans")  in which any  employees  of the  Company  participate.  All
obligations of the Company,  whether arising by operation of law, by contract or
by past custom, for payment by it to trusts,  retirement plans or other funds or
any  governmental  agency with respect to  unemployment  compensation  benefits,
social security benefits or any other benefits for employees of the Company have
been paid or shall be paid by the Company at the time the  Company is  obligated
to make such payments.  All benefits payable directly to the Company's employees
have  been  paid or shall be paid by the  Company  at the  time the  Company  is
obligated to make such payments. All reasonably  anticipated  obligations of the
Company, whether arising by operation of law, by contract or by past custom, for
vacation and holiday pay,  bonuses and other forms of  compensation  or benefits
which are or may become  payable to employees or any of them have been paid,  or
shall  be  paid,  in  accordance   with  the  provisions  of  applicable   laws,
regulations, benefit plans or policies.



                        (ii)  All  Plans,  related  trust  agreements,   annuity
contracts or other funding  arrangements comply in all substantial  respects and
the  Company  has  administered  and  operated  each such  Plan,  related  trust
agreements,  annuity  contracts or other  funding  arrangements  in  substantial
compliance  with  the  requirements  of  applicable  law,   including,   without
limitation,  the  Employee  Retirement  Income  Security  Act of 1974 as amended
("ERISA"),  and the Code, and no such Plan that is subject to Part 3 of Subtitle
B of Title I of ERISA has incurred any "accumulated  funding  deficiency" within
the meaning of Section  302 of ERISA or Section 412 of the Code,  whether or not
waived.





                                      8





                        (iii) The Company  does not maintain and is not required
to contribute to any multi-employer  plan (as defined in Section 3(37) of ERISA)
for the benefit of  employees or former  employees  of the Company.  The Company
does not maintain a self-insured  "multiple  employer  welfare  arrangement"  as
defined in Section 3(40) of ERISA.

                        (iv)  The Pension Benefit Guaranty  Corporation ("PBGC")
has not instituted proceedings to terminate any of the Company's defined benefit
plans and no condition exists that presents a risk that such  proceedings  shall
be  instituted.  There has been no  "reportable  event"  within  the  meaning of
Section 4043(b) of ERISA with respect to any defined benefit plan and no defined
benefit plan has been  terminated  within the preceding six years or is expected
to be terminated.  No liability  (other than for the payment of premiums) to the
PBGC has been or is  expected  to be  incurred  by the  Company or any  officer,
director,  shareholder  or employee of the Company  with  respect to any defined
benefit plan.

                        (v)   The Company has no  liability  with respect to any
transaction  which relates to any Plan and which is in violation of Sections 404

All of the documents  listed on Schedule 3.22 hereof and the contracts listed as
exhibits to the  Company's  filings  with the SEC are  hereinafter  collectively
referred  to as  the  "Commitments."  To  the  knowledge  of  the  Company,  the

obligations of the parties  thereto in accordance  with their  respective  terms
(except as may be limited by the laws of  bankruptcy,  insolvency  or  creditors
rights generally and subject to the enforceability and availability of equitable
remedies),  and to the  knowledge  of the  Company,  no  defenses,  off-sets  or

directly or indirectly,  on an individual or joint basis, any interests, has any
investment in or serves as an officer,  partner or director in any  corporation,
business  or other  person that is a customer,  supplier  or  competitor  of the
Company,  or that has a material contract or arrangement with the Company or its
competitor,  other  than the  ownership  of less  than one  percent  (1%) of the
securities of any company that are publicly  traded on any national  exchange or

neither the Company nor any of its assets is currently in material violation of,
or subject to any material  existing,  pending or  threatened  investigation  or
inquiry by any governmental  authority or to any remedial  obligations under any
environmental  laws, and this  representation  and warranty would continue to be
true and correct following disclosure to the applicable governmental authorities
of all relevant facts,  conditions and circumstances,  if any, pertaining to the
assets and operations of the Company. To the Company's knowledge,  the assets of
the Company have never been used in a manner that would be in material violation
of any of the environmental laws. To the Company's knowledge, the Company is not
required to obtain any permits, licenses or similar authorizations to construct,
occupy, operate or use any buildings, improvements, fixtures and equipment owned
or leased by the Company by reason of any environmental laws. None of the assets
owned or leased by the Company are on any federal or state  "Superfund"  list or
subject to any environmentally related liens.

                  3.25 No  Bankruptcies.  For the past five  years,  neither the
Company nor any of its officers, directors or its or their affiliates, have been
subject  to  criminal   investigation,   adjudication   or  conviction  or  have
voluntarily sought, consented to or acquiesced in the benefits of, or become the
subject of a proceeding  under the  Bankruptcy  Code of the United States or any
other   applicable   liquidation,   conservatorship,   bankruptcy,   moratorium,
rearrangement, receivership, insolvency, reorganization or similar debtor relief
laws from time to time in effect affecting the rights of creditors generally.

                  3.26 Year 2000  Compliance.  To the Company's  knowledge,  the
computer systems used by the Company are Year 2000 compliant,  meaning that such
systems will continue to function,  and  functionality  and accuracy will not be
affected  as a  result  of the run  date or the  dates  being  processed  in the

from the extra day occurring in any leap year.

health  laws  and  regulations),  and the  Company  is not in  violation  of any
judgment,  order or decree. There is no existing law, rule,  regulation or order
which would  prohibit or restrict  the Company  from,  or  otherwise  materially
adversely affect the Company in,  conducting its business in any jurisdiction in
which it is now conducting business or, to the Company's knowledge,  in which it
proposes to conduct business.

                  3.28 Disclosure. This Agreement and the exhibits and schedules

to the  date of  this  Agreement  that  materially  and  adversely  affects  the
business, assets, properties, prospects or condition (financial or otherwise) of
the Company,  taken as a whole,  or the ability of the Company to perform  under
this Agreement or the other agreements  contemplated hereby or to consummate the
