Purchaser's  effecting a cash  tender  offer to purchase up to 75% of the issued
and outstanding shares of common stock, $.02 par value per share, of the Company

          WHEREAS, the Company,  OS  and   Purchaser   desire  to  make  certain
representations,  warranties,  covenants and agreements in connection  with this
Agreement.

          NOW, THEREFORE, in consideration of the foregoing  and the  respective
representations,  warranties,  covenants and  agreements  set forth herein,  the
parties hereto agree as follows:

                                    SECTION I

                                THE TENDER OFFER

          A. Tender  Offer.  (i)  Provided  that this  Agreement  shall not have
been   terminated  in  accordance  with  Section  X   hereof,  as   promptly  as
practicable  (but in no event later than eight (8) business  days  following the
execution and delivery of this  Agreement,  unless the Company and the Purchaser
have otherwise agreed), Purchaser will commence a tender offer (the "Offer") for
up to 1,959,886 Shares (representing 75% of the Shares currently  outstanding as
represented by the Company in Section III.D) at a price of $1.525 per Share, net
to the seller in cash (as such Offer may be amended in accordance with the terms
of this  Agreement)  (the  "Offer  Price"),  which Offer shall be subject to the
terms and conditions set forth in Annex A hereto (the "Offer  Conditions").  The
initial expiration date of the Offer shall be the date 20 business days from and
including  the  date  (the  "Commencement  Date")  the  Offer is  commenced  (in
accordance with the applicable  regulations).  Purchaser  expressly reserves the
right, in its sole discretion, to waive any condition and to set forth or change
any other term or  condition  of the Offer,  provided  that,  unless  previously
approved  by the Company in writing,  no  provision  may be set forth or changed
which  decreases the price per Share  payable in the Offer,  changes the form of
consideration  payable in the Offer  (other  than by adding  consideration),  or
imposes conditions to the Offer in addition to those set forth herein that are

materially  adverse  to  holders  of  the Shares. Purchaser covenants and agrees
that,  subject  to the terms and  conditions  of the  Offer,  including  but not
limited to the Offer  Conditions and the provisions  regarding  proration of the
Shares to be  purchased,  it will  accept  for  payment  and pay for all  Shares
validly tendered and not withdrawn that it is obligated to purchase (i.e., if at
least 1,959,886  Shares are tendered,  then 1,959,886 Shares will be purchased),
as soon as it is permitted to do so under  applicable law.  Purchaser shall have
the  right,  in its sole  discretion,  to extend  the  Offer  from time to time;
provided,  however, that, without the written consent of the Company,  Purchaser
cannot extend the Offer for more than five business days unless  applicable laws
or regulations so require or a condition  which is a prerequisite  to fixing the
Closing  Date has not been  satisfied.  In  addition,  the  Offer  Price  may be
increased  and the  Offer  may be  extended  to the  extent  required  by law in
connection with such increase in each case without the consent of the Company.

          (ii) The  Company  hereby  approves  of and  consents to the Offer and
represents and warrants  that:  (i) its Board of Directors  (the "Board"),  at a
meeting duly called and held on December 19, 2000,  unanimously  (A)  determined
that this  Agreement and the  transactions  contemplated  hereby,  including the
Offer,  are fair to and in the best  interests  of the  holders of  Shares,  (B)
approved this Agreement and the transactions  contemplated hereby, including the
Offer, and (C) resolved to recommend, subject to its continued fiduciary duties,
that the stockholders of the Company accept the Offer and tender their Shares to
Purchaser;  and (ii) Cronkite & Kissell (the "Financial  Advisor")  delivered to
the Board on  December  28,  2000,  its  opinion  that the  consideration  to be
received by holders of Shares  pursuant to the Offer is fair to such holders and
the Company from a financial point of view and such opinion has not been revoked
or withdrawn.  The Company has been  authorized  by the Financial  Advisor (such
consent not to be  unreasonably  withdrawn),  to include a copy of such fairness
opinion (or a reference thereto) in a  Solicitation/Recommendation  Statement on

made by  Purchaser  with respect to the  information  supplied by the Company in
writing for inclusion in the Offer  Documents.  Purchaser  further agrees to use

past  practices or (y) contracts and  agreements  specifically  contemplated  or
required by the terms and conditions of this Agreement, (ii) permitted any liens
or  encumbrances to attach to any of the assets of the Company or (iii) provided
any loan,  advance,  guaranty  or other  financial  accommodation  to or for the
benefit of any other person or entity.  The Company is not liable for or subject
to any liabilities  except (x) those liabilities  reflected on the balance sheet
contained in the Company's  quarterly report on Form 10-Q for its fiscal quarter
ended August 26, 2000 (the "Interim Balance Sheet"); (y) trade accounts payable,
accrued  payroll,  accrued payroll taxes,  and other current  liabilities of the
Company arising in the ordinary course of business consistent with past practice
since such date;  and (z) those  liabilities  arising in the ordinary  course of
business  consistent  with past  practice  under  any  contract,  commitment  or
agreement set forth on the Company Disclosure  Schedule.  The Company Disclosure
Schedule  sets  forth a detailed  budget of all  capital  expenditures,  hiring,
compensation  increases,  contracts  (providing for payments from or receipts by
the  Company in excess of  $12,500),  leases and other  commitments  incurred or
planned by the Company since the date of the Interim Balance Sheet.

          J. Real  Property  Owned or Leased.  The Company does not own any real
property.  A list and  description  of all  real  property  leased  to or by the
Company or in which the  Company  has any  interest  is set forth in the Company
Disclosure  Schedule  ("Company  Premises").  All leased  real  property is held
subject to written leases or other  agreements  which are valid and effective in
accordance  with their  respective  terms,  and,  to the best  knowledge  of the
Company,  except for  "Immaterial  Defaults"  (as  defined  below)  there are no
existing defaults or events of default,  or events which with notice or lapse of
time  or  both  would  constitute  defaults,  other  than  Immaterial  Defaults,
thereunder  on  the  part  of the  Company.  For  purposes  of  this  Agreement,

                                      -8-
<PAGE>

Immaterial Defaults are defaults which do not, individually or in the aggregate,
cause the Company to fail to comply in all material  respects with the terms and
conditions of the applicable lease, contract,  agreement or instrument. All rent
and other  charges due and owing by the Company under any lease has been paid in
full and there are no disputes or claims between the Company and any other party
to any lease.  No  construction,  improvements,  or alterations  are in process,
under  construction or planned at any Company Premises,  other than the movement
of  partitions  and similar  activities  in  connection  with the  relocation of
Company  personnel.  The Company has no  knowledge  of any  material  default or
claimed or  purported or alleged  material  default or state of facts which with
notice or lapse of time or both would  constitute a material default on the part
of any other party in the  performance of any obligation to be performed or paid
by such  other  party  under any lease  referred  to in the  Company  Disclosure
Schedule.  The Company has not received any written or oral notice to the effect
that any lease  will not be renewed at the  termination  of the term  thereof or
that any such lease will be renewed only at a substantially higher rent.

          All structural,  mechanical and other physical systems,  including but
not limited to heating,  ventilating,  air conditioning,  plumbing,  electrical,
mechanical, sewer and drainage systems at Company Premises are in good operating
condition and repair. All water, sewer, gas, electric,  telephone,  drainage and
other  utilities  required  for use and  operation  of the Company  Premises are
connected  to municipal or public  utility  services and are fully  operable and
adequate to service the  operation of the business of the Company at the Company
Premises.  The Company  Premises  and all  present  uses and  operations  at the
Company  Premises,  including  the  conduct of the  business  of the Company and
related  manufacturing  activity,  comply  in all  material  respects  with  all
statutes, rules, regulations, ordinances, orders, judgments, and restrictions of
any government entity having jurisdiction thereon (including without limitation,
applicable  zoning,  land  use,  fire,  building  codes,   safety,   health  and
handicapped  access  requirements),  as  well  as  all  covenants,   conditions,
restrictions,  easements and similar matters affecting the Company Premises. The
Company has obtained all  Certificates of Use and Occupancy and similar licenses
and permits  required in connection with the use of the Company Premises for the
conduct of the business of the Company. To the Company's knowledge, there are no
pending or threatened condemnation, fire, health, safety, building, zoning, land
use, assessment,  or similar proceedings relating to the Company Premises. There
are no parties other than the Company in possession of any Company  Premises and
there are no sublease,  concession,  occupancy,  license or similar arrangements
affecting the Company Premises.

          K. Title to Assets;  Condition of  Property.  The Company has good and
valid title to the assets owned by the Company,  including,  without limitation,
the  properties  and assets  reflected in the Interim  Balance Sheet (except for
assets  leased  under  leases  set  forth in the  Company  Disclosure  Schedule,
inventory  and other  assets sold or retired and accounts  receivable  collected
upon, since August 26, 2000, in the ordinary course of business  consistent with
past practices).  The Company leases, licenses or owns all properties and assets
used or  necessary  for  use in the  operations  of its  business  as  currently
conducted  other than  inventory  and supplies  which need to be  purchased  and
replenished  in the  ordinary  course of  business;  except for motor  vehicles,
inventory held by certain of the Company's suppliers and personal items assigned
to individual employees, such as mobile phones, pagers and laptop computers, all
of such assets are located on Company  Premises.  All such properties and assets
are in all material  respects in good  condition  and repair,  ordinary wear and
tear excepted,  consistent with their  respective ages, and have been maintained
and  serviced  in

                                       -9-

<PAGE>

accordance  with  the  normal  practices  of the Company and as necessary in the
normal course of business.  None of the assets of the Company are subject to any
liens,  charges,  encumbrances or security  interests except as set forth in the
agreements listed in the Company Disclosure Schedule and for liens for taxes not
yet due and payable or which are being  contested  in good  faith;  and liens of
mechanics, materialmen,  warehouseman,  carriers, landlords and other like liens
securing  obligations  incurred in the ordinary  course of business that are not
yet due and  payable or which are being  contested  in good  faith.  None of the
assets of the Company (or uses to which they are put) fails to conform  with any
applicable  agreement,  law, ordinance or regulation in a manner which is likely
to be materially  adverse to the operations of the business of the Company.  The
Company  Disclosure  Schedule  sets forth a complete and  accurate  Depreciation
Lapse Schedule as of November 25, 2000,  with respect to the Company's  personal
property.  All leases of personal  property used by the Company and set forth on
the Company  Disclosure  Schedule  are in full force and effect and all rent and
other charges thereunder have been paid by the Company.

          L. Taxes.  The Company and each  Subsidiary  has filed or caused to be
filed on a timely  basis  all  federal,  state,  local,  foreign  and  other tax
returns, reports and declarations  (collectively,  "Tax Returns") required to be
filed by it.  All Tax  Returns  filed by or on  behalf of the  Company  and each
Subsidiary are true, complete and correct in all material respects.  The Company
and each Subsidiary has paid all income,  estimated,  excise,  franchise,  gross
receipts, capital stock, profits, stamp, occupation, sales, use, transfer, value
added,  property  (whether  real,  personal  or  mixed),  payroll,   employment,
unemployment,  disability,  withholding,  social security, workers' compensation
and  other  taxes,  and  interest,   penalties,  fines,  costs  and  assessments
(collectively, "Taxes"), reflected as due and payable on such Tax Returns. There
are no tax liens on any of the  properties or assets,  real,  personal or mixed,
tangible or  intangible,  of the Company or any of the  Subsidiaries  except for
liens for Taxes not yet due and  payable  or which are being  contested  in good
faith.  The accrual for Taxes reflected in the Financial  Statements  accurately
reflects  the total  amount of all unpaid  Taxes,  whether or not  disputed  and
whether or not presently due and payable,  of the Company and each Subsidiary as
of the close of the periods covered by the Financial Statements,  and the amount
of the Company's and each Subsidiary's  unpaid Taxes on August 26, 2000 does not
exceed in any material  respect the accrual for Taxes reflected in the Financial
Statements  for the period ended August 26,  2000.  The amount of the  Company's
liability for unpaid Taxes for all periods or portions thereof ending August 26,
2000 did not exceed in any material respect the amount of the current  liability
accruals for Taxes,  as such accruals were reflected on the books and records of
the Company on August 26, 2000.  Since August 26, 2000,  neither the Company nor
any of the  Subsidiaries  has  incurred  any  Tax  liability  other  than in the
ordinary  course of  business.  No  deficiency  in Taxes for any period has been
asserted by any taxing  authority  which remains  unpaid at the date hereof (the
results of any settlement being set forth in the Company  Disclosure  Schedule),
no written  inquiries or notices have been received by the Company or any of the
Subsidiaries  from any taxing  authority  with  respect to  possible  claims for
Taxes,  and neither the  Company nor any of the  Subsidiaries  has any reason to
believe  that such an inquiry or notice is pending or  threatened,  and,  to the
best knowledge of the Company,  there is no basis for any  additional  claims or
assessments  for Taxes.  Neither  the Company  nor any of the  Subsidiaries  has
agreed to the  extension of the statute of  limitations  with respect to any Tax
Return or Tax period. The Company and each Subsidiary has delivered to OS copies
of the  federal  and state  income Tax  Returns  filed by the  Company  and each
Subsidiary  for the past three years and for all other past  periods as to which
the appropriate statute of limitations has not lapsed.

          None of the Company's  assets are treated as "tax exempt use property"
within the meaning of Section  168(h) of the Internal  Revenue Code of 1986,  as
amended (the "Code"). There are no contracts, agreements, plans or arrangements,
covering any employee or former  employee of the Company,  that  individually or
collectively,  could give rise to the payment of any amount (or portion thereof)
that could not be deductible  pursuant to Section 280G,  404 or 162 of the Code.
The Company has not filed any consent agreement under Section 341(f) of the Code
or agreed to have 341(f) of the Code apply to  disposition of any asset owned by
the Company.  The Company's  tax basis in its assets is accurately  reflected on
the Company's tax books and records.  The Company Disclosure Schedule sets forth
the  Company's  federal and state "Net  Operating  Losses" and tax credits as of
February 29, 2000.

          M.   Permits; Compliance with Applicable Law.

          (i) General. The Company is not in default under any, and has complied
in all material respects with all, federal,  state,  local and foreign statutes,
ordinances, regulations and laws (including, but not limited to, all federal and
state  fraud and abuse,  "anti-kickback"  and "self-  referral"  laws),  and all
orders,  judgments  and decrees of any court or  governmental  entity or agency,
relating to the Company,  its business or any of the assets of the Company.  The
Company has no  knowledge  of any basis for  assertion  of any  violation of the
foregoing or for any claim for compensation or damages or otherwise  arising out
of any violation of the foregoing. The Company has not received any notification
of any asserted present or past failure to comply with any of the foregoing.

          (ii)  Permits.  Set  forth in the  Company  Disclosure  Schedule  is a
complete and  accurate  list of all permits,  licenses,  approvals,  franchises,
notices and authorizations  issued by governmental  entities or other regulatory
authorities,  federal, state or local (collectively the "Permits"),  held by the
Company in connection  with its business.  To the best knowledge of the Company,
the  Permits set forth in the Company  Disclosure  Schedule  are all the Permits
required or  appropriate  for the conduct of its  business.  All the Permits set
forth in the Company  Disclosure  Schedule are in full force and effect, and the
Company has not engaged in any activity  which would cause or permit  revocation
or  suspension  of any such Permit,  and no action or  proceeding  looking to or
contemplating  the revocation or suspension of any such Permit is pending or, to
the best knowledge of the Company,  threatened.  There are no existing  material
defaults  or events of default or event or state of facts  which with  notice or
lapse of time or both would  constitute a material  default by the Company under
any such  Permit.  The  Company  has no  knowledge  of any default or claimed or
purported  or alleged  default or state of facts  which with  notice or lapse of
time or both would  constitute  a default on the part of any other  party in the
performance  of any  obligation to be performed or paid by any other party under
any Permits set forth in the Company Disclosure Schedule. The use by the Company
of any  proprietary  rights  relating to any Permit does not involve any claimed
infringement of such Permit or rights.

          (iii)     Environmental.

               (a)  The Company has no liability under, has never violated, and
is presently in compliance in all material respects with all environmental,

the  Company  Premises,  that  could or do result  in any  damage,  loss,  cost,
expense,  claim,  demand,  order or  liability  to or against the Company by any
third party  including,  without  limitation,  any condition  resulting from the
operation  of the  business of the  Company,  except as set forth in the Company
Disclosure Schedule or except for such conditions which,  individually or in the
aggregate,  do not cause the Company to fail to comply in all material  respects
with applicable Environmental Laws and contractual obligations.

               (c)  The  Company  has  not  generated,  manufactured,   refined,
transported,  treated,  stored,  handled,  disposed,  transferred,  produced, or

("Hazardous  Material")  or any solid waste at the Company  Premises,  or at any
other location,  except in compliance with all applicable Environmental Laws and
except as listed in the Company Disclosure Schedule.

               (d) The  Company has no  knowledge  of the  releasing,  spilling,
leaking, pumping, pouring, emitting, emptying, discharging, injecting, escaping,

surface waters,  ground waters,  land, stream  sediments,  surface or subsurface
strata,  ambient air, sewer system, or any environmental  medium with respect to
the  Company  Premises  ("Environmental  Condition"),  except  as  listed in the
Company Disclosure Schedule.

               (e)  No lien has been imposed on the Company Premises by any
governmental entity at the federal, state, or local level in connection with the
presence on or off the Company  Premises of any  Hazardous  Material,  except as
listed in the Company Disclosure Schedule.

               (f) The Company has not (i) entered  into or been  subject to any
consent decree,  compliance order, or  administrative  order with respect to the
Company Premises or any facilities or operations  thereon;  (ii) received notice
under the citizen suit provision of any of the Environmental  Laws in connection
with the  Company  Premises  or any  facilities  or  operations  thereon;  (iii)
received any request for  information,  notice,  demand  letter,  administrative
inquiry,  or  formal  or  informal  complaint  or  claim  with  respect  to  any
Environmental  Condition  relating to the Company  Premises or any facilities or
operations  thereon; or (iv) been subject to or threatened with any governmental
or citizen  enforcement  action  with  respect to the  Company  Premises  or any
facilities or operations thereon,  except as set forth in the Company Disclosure
Schedule;  and the  Company  has no  knowledge  that  any of the  above  will be
forthcoming.

               (g)  The   Company  has  all   permits   necessary   pursuant  to
Environmental Laws for the conduct of the Company's activities and operations at
the Company Premises and for any past or ongoing  alterations or improvements by

Disclosure Schedule.

                                      -12-
<PAGE>

               (h) None of the  following  exists  at the  Company  Premises  in
amounts or conditions which, individually or in the aggregate, cause the Company
to fail to comply in all material respects with applicable  Environmental  Laws:
(1) underground storage tanks, (2) asbestos-containing  materials in any form or
condition, (3) materials or equipment containing  polychlorinated biphenyls, (4)
lead paint, pipes or solder, or (5) landfills,  surface impoundments or disposal

               (i) The  Company  has  provided  to OS copies  of all  documents,
records and information in its possession or control or available to the Company
concerning  Environmental  Conditions  relevant to the  Company  Premises or any
facilities  or  operations  thereon,  whether  generated  by  Company or others,
including,   without  limitation,   environmental  audits,   environmental  risk
assessments,  or  site  assessments  of  the  Company  Premises,   documentation
regarding  off-site  disposal of Hazardous  Materials,  spill control plans, and
environmental agency reports and correspondence.

               (j) The  Company  has taken or  caused  to be taken  all  actions
necessary  to  ensure  that as of the  consummation  of the  Offer  the  Company
Premises,  all  activities  and  operations  thereon,  and all  alterations  and
improvements  thereto,  comply  in all  material  respects  with all  applicable
Environmental  Laws and with any and all agreements with governmental  entities,

          (iv)  Product  Requirements.  Except  as  set  forth  on  the  Company
Disclosure  Schedule,  the  manufacture,   distribution  and  marketing  of  the
Company's  products  does not require the consent or approval  of, or any filing
with, the United States Food and Drug  Administration or any other  governmental
agency.  The Company sells its products at wholesale to distributors,  retailers
and  professionals  for use by their  customers and patients and, except for its
Protect  and  Repairs  program,  does not sell any of its  products at retail or
directly to consumers or patients. The Company does not look to any governmental
agency  (Medicare,  Medicaid,  etc.) or  insurance  carrier  for payment for its
products.  Accordingly,  the Company does not require any  Medicare/Medicaid  or
similar  vendor numbers or  registrations.  The activities of the Company do not
require that it or any of its  employees  qualify or maintain  any  professional
license  or  require  that  the  Company  or  any of its  employees  obtain  any
certification from a trade group or similar self-regulatory body.

          (v) Government  Relations.  The Company has not,  offered or agreed to
offer  anything  of  value  to any  governmental  official,  political  party or
candidate  for  government  office,  nor has it otherwise  taken any action that
would cause the Company to be in violation of the Foreign Corrupt  Practices Act
of 1977, as amended,  or any law of similar  effect.  Except as set forth on the
Company  Disclosure  Schedule,  the  Company  is not a party  to any  government
contracts.  The  Company has not been  suspended  or  debarred  from  bidding on
contracts  or  subcontracts  for any agency or  instrumentality  of any federal,
state,  local or foreign  government.  The Company has never been the subject of

any  consent  decree,   compliance  order,   administrative   order,  or  a
Cooperative Compliance Plan with respect to OSHA.

          N.   Inventories; Accounts Payable; Accounts Receivable.

          (i) Inventory.  The Company's  Disclosure Schedule includes a complete
and accurate list of the Company's inventory, other than work in progress, as of
November 25, 2000 (the  "Run").  The  inventory  of the Company  consists of raw
materials and supplies,  manufactured and purchased parts,  goods in process and
finished goods, all of which are merchantable and fit for the purposes for which
they were procured or manufactured,  and none of which is slow moving, obsolete,
damaged,  or  defective,  subject  to a  reserve  for  inventory  calculated  in
accordance  with generally  accepted  accounting  principles  applied on a basis
consistent with the past practices of the Company.  The inventory of the Company
is valued in accordance with generally accepted accounting principles applied on
a basis consistent with the past practices of the Company.

          (ii)  Accounts  Payable.  The  accounts  and notes  payable  and other
accrued  expenses  reflected on the Interim Balance Sheet,  and the accounts and
notes payable and accrued expenses incurred by the Company  subsequent to August
26, 2000, are in all respects  valid payables that arose in the ordinary  course
of business.  Since August 26,  2000,  the accounts and notes  payable and other
accrued expenses of the Company have been paid in a manner  consistent with past
practice.

receivable of the Company  (including  without  limitation  receivables from and
advances to employees,  officers, directors and consultants),  which includes an
aging of all accounts and notes  receivable  showing  amounts due in thirty (30)
day  aging  categories.  All  accounts  and  notes  receivable  of  the  Company
(collectively,  the "Accounts  Receivable")  represent valid obligations arising
from sales actually made or services  actually  performed in the ordinary course
of business.  The Company has no reason to believe that its Accounts  Receivable
will not be collected in the ordinary  course,  net of any  respective  reserves
shown on the  Company's  books and records  (which  reserves  are  adequate  and
calculated consistent with past practice). There currently is no contest, claim,
or right of setoff,  other than  rebates and returns in the  ordinary  course of
business,  under any contract with any obligor of an Account Receivable relating
to the amount or validity of such Account Receivable.

          O. Contractual and Other Obligations; Significant Customers. Set forth

thereunder and the collateral, if any, for such borrowings) other than contracts

material  respect,  in the  performance  of any covenant or condition  under any
Contract and no claim of such a default has been made, (B) to the best knowledge

transactions  contemplated  by this  Agreement.  Originals or true,  correct and
complete copies of all Contracts have been provided to OS.

result in a reversal of any material revenue.

person   will   receive   any   increase   in  compensation  or  benefits or any

          Q.  Employee  Benefit  Plans.  Except  as set  forth  in  the  Company
Disclosure Schedule, the Company does not maintain or sponsor, or contribute to,
any pension, profit-sharing, savings, bonus, incentive or deferred compensation,
severance pay, medical, life insurance,  welfare or other employee benefit plan.
All pension, profit-sharing, savings, bonus, incentive or deferred compensation,
severance pay, medical, life insurance,  welfare or other employee benefit plans
within the meaning of Section 3(3) of the Employee  Retirement  Income  Security
Act of 1974,  as amended  (hereinafter  referred  to as  "ERISA"),  in which the
Company's  employees  participate  are  hereinafter  referred to as the "Benefit
Plans".  All Benefit Plans comply in all material respects with all requirements
of the Department of Labor and the Internal Revenue Service,  and with all other
applicable laws and regulations and the constituent  documents and terms of such
Benefit  Plans,  and the Company has not taken or failed to take any action with
respect to the Benefit Plans which might create any liability on the part of the
Company  except for claims in the ordinary  course for benefits  with respect to
the Benefit Plans and any requirements of the Company to contribute to a Benefit
Plan as set  forth in the terms  and  conditions  of such  Benefit  Plan.  True,
correct and  complete  copies of the  following  documents  with respect to each
Benefit  Plan  have been  delivered  by the  Company  to OS:  (A) all  documents
constituting the Benefit Plan,  including but not limited to, trust  agreements,
plan documents,  insurance policies and amendments thereto,  (B) the most recent

valuations for the three (3) years preceding the date of this Agreement; (F) all
notices  that have been given to the Company or such  Benefit  Plans  within the
three (3) years  preceding the date of this Agreement by the IRS,  Department of
Labor,  or any other  governmental  agency with respect to any Benefit Plan, and
(G) all employee manuals or handbooks containing personnel or employee relations
policies of the Company. No Benefit Plan contains any provision or is subject to
any legal requirement that would prohibit the transactions  contemplated by this
Agreement  or that  would  give  rise to any  vesting  of  benefits,  severance,
termination or other  payments or  liabilities  as a result of the  transactions
contemplated by this Agreement.  The Benefit Plans are not presently under audit
or  examination   (nor  has  notice  been  received  of  a  potential  audit  or
examination)  by the IRS,  the  Department  of Labor or any  other  governmental
agency.  With respect to each Benefit  Plan,  there has occurred no  "prohibited
transaction" within the meaning of the Code or ERISA. In addition:

Service as to its qualification;

Company does not maintain,  sponsor or contribute to, and has never  maintained,
sponsored or  contributed  to, a "defined  benefit  plan" (within the meaning of
Section 3(35) of ERISA) or a "multiemployer plan" (within the meaning of Section
3(37) of ERISA);

          (iii) Except as set forth in the Company  Disclosure  Schedule,  there
are no  contributions  which are or hereafter will be required to have been made
to trusts in connection  with

                                      -16-
<PAGE>

any   Benefit  Plan  that  would  constitute   a  "defined  contribution   plan"
(within the meaning of Section 3(34) of ERISA);

          (iv) Other  than  claims in the  ordinary  course  for  benefits  with
respect to the Benefit Plans,  there are no actions,  suits or claims (including
claims for income Taxes, interest, penalties, fines or excise Taxes with respect
thereto)  pending with respect to any Benefit Plan, or, to the best knowledge of
the Company, any circumstances which might give rise to any such action, suit or
claim (including claims for income Taxes, interest,  penalties,  fines or excise
Taxes with respect thereto); and

          (v) The Company has no obligation  to provide  health or other welfare
benefits to former,  retired or  terminated  employees,  except as  specifically
required  under Section  4980B of the Code or Section 601 of ERISA.  The Company
has complied with the notice and  continuation  requirements of Section 4980B of
the Code and Section 601 of ERISA and the regulations thereunder.

ordinances,  rules,  regulations,  orders  or  directives  with  respect  to the
employment of individuals by, or the employment practices or work conditions of,
the Company,  or the terms and  conditions of employment,  wages and hours.  The
Company is not engaged in any unfair labor practice or other unlawful employment
practice  and  there  are  no  charges  of  unfair  labor   practices  or  other
employee-related  complaints  pending or, to the best  knowledge of the Company,
threatened  against the Company before the National Labor Relations  Board,  the
Equal Employment  Opportunity  Commission,  the  Occupational  Safety and Health
Review Commission, the Department of Labor or any other federal, state, local or
other governmental authority.  There is no strike,  picketing,  slowdown or work
stoppage or  organizational  attempt  pending,  threatened  against (to the best
knowledge  of the Company) or  involving  the business of the Company.  No issue
with respect to union representation is pending or, to the best knowledge of the
Company,  threatened  with respect to the employees of the Company.  No union or
collective  bargaining unit or other labor  organization has ever been certified
or  recognized by the Company as the  representative  of any of the employees of
the Company.

          S.  Increases in  Compensation  or Benefits.  Subsequent to August 26,
2000,  there have been no  increases  in the  compensation  payable or to become
payable to any of the employees of the Company  earning in excess of $40,000 per
annum and there have been no payments  or  provisions  for any awards,  bonuses,
loans, profit sharing, pension,  retirement or welfare plans or similar or other
disbursements  or  arrangements  for or on behalf of such  employees (or related
parties  thereof),  in  each  case,  other  than  as set  forth  in the  Company
Disclosure  Schedule.  Except for bonuses  that may be due to  employees  of the
Company for the current  year as set forth in the Company  Disclosure  Schedule,
all bonuses  heretofore  granted to  employees  of the Company have been paid in

earn three weeks  vacation per year which can be carried  forward for two years.
No employee of the Company is entitled to vacation time in excess of three weeks
in respect of the current  calendar year and no employee of the Company has more
than six weeks  accrued  vacation  time in respect of prior years or any accrued
sick time with respect to any prior year which can be carried forward.

          G.   Existing Options.  Prior  to  the  purchase  of  the  Shares  the
Company will redeem from each of the individuals set forth on Schedule V. G  the
Options to  purchase  Shares  set  forth  opposite  their respective names.  The
aggregate  redemption  price  to  be  paid to each individual will be the amount
indicated on Schedule V. G.

          H.   Provision  of Information. During the period commencing as of the
date hereof and ending on the Closing  Date, Andrew  H.  Meyers, the Chairman of
OS, and Stephen V.  Ardia, the Chairman of the Company, will coordinate so as to
provide Mr. Meyers with data and information on the Company's operations.

          I. Interim Employment. From the date hereof through the earlier of the
Closing Date or the termination of this Agreement,  Mr. Meyers shall be employed
by the Company in an advisory  capacity and be appointed  an  "Observer"  to the
Board with the right to receive all  notices  and reports  provided to the Board
and to attend  all  meetings  of the Board  except  that he shall not be able to
receive  reports  or vote,  and  shall  recuse  himself  from all  deliberations
regarding  the  transactions  contemplated  by this  Agreement or the  Company's
relationship  with Mr. Meyers,  OS or Purchaser (if a meeting  relates solely to
the  transactions  contemplated by this Agreement,  it is contemplated  that Mr.
Meyers will not be invited to attend such meeting). Mr. Meyers shall not receive
any compensation  for services  rendered prior to the consummation of the Offer,
but shall be reimbursed for agreed upon expenses.

          J. Individual Options.  The Stock Option Agreement between the Company
and Mr.  Meyers dated the date hereof in the form of Exhibit V. J(i)  (providing
for the grant of options concurrently herewith),  shall be effective on the date
hereof.  Such  Stock  Options  shall  not  become  exercisable  until,   without
limitation, the Closing Date and the approval by the Stockholders of the Company
of an increase in the shares  underlying  the Stock Option  Plan.  The Board has
confirmed  its  acceptance of the terms of the Stock Option  Agreement  with Mr.
Meyers in a resolution  adopted by the Board. The Company shall not be deemed in
violation  of the  covenants in this  Section V. J if Mr.  Meyers  elects not to
serve the Company or the Company has the right to terminate his  employment  and
Stock Option Agreement for "Cause" as reasonably determined by the Board.

          K. Option Grant.  To enable OS to fund the growth of the Company,  the
Company will grant to OS or its  designees  effective the Closing Date an option
to purchase up to 1,400,000  Shares (the "OS Options").  The OS Options shall be
exercisable  for a period of one- hundred eighty days  commencing on the Closing
Date. The exercise price of the OS Options shall  initially be $1.525 per share;
shall increase to $1.550 per share ninety-one days after the Closing Date, shall
increase to $1.575 per share one-hundred  twenty one days after the Closing Date
and shall be $1.60  per share  from the  one-hundred  fifty  first day after the
Closing Date until the  expiration  of the OS Options.  The OS Options  shall be
evidenced by an Option Agreement in the form of Exhibit V. K.

          The Offer  Documents  will disclose that the OS Options may or may not
be  exercised;  that the Company may need  additional  financing  to achieve its
growth  objectives  and that,  subject to  approval of the then  current  Board,
financing  may be  provided by OS or other  related  parties  upon other  terms,
including by the purchase of convertible notes or preferred stock of the Company
or

                                      -27-
<PAGE>

other  methods  and  the  sale  prices,  conversion   prices,  or  the  exercise
prices of such  securities may be lower or higher than the exercise price of the
OS Options or the then current market price of the Shares.

          L. Transaction Costs. It is estimated that the legal fees and fairness
opinion  costs  incurred  by the  Company in  connection  with the  negotiation,
documentation   and  consummation  of  the  transactions   contemplated   hereby
(collectively,  the  "Transaction  Costs") shall be $150,000.  The Company shall
notify  OS if the  Transaction  Costs are  reasonably  expected  to exceed  that
amount.

          M.  Filings.  The Company shall comply with all  requirements  imposed
upon  it  by  the  Exchange  Act  and  the  rules  and  regulations  promulgated
thereunder.  All  reports  required  by the  Exchange  Act and  such  rules  and
regulations  will be timely  filed,  will  comply with the  requirements  of the
Exchange Act and the rules and regulations promulgated thereunder,  and will not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements  made therein,
in light of the circumstances in which they were made, not misleading.

Subsidiary  and each committee of each such board (in each case to the extent of
the  Company's  ability to elect such  persons) as  Purchaser's  representatives
constitute of the Board. The Company's obligations to facilitate the appointment
of designees of Purchaser to the Board shall be subject to Section  14(f) of the
Exchange Act and Rule 14f-1 promulgated  thereunder.  The Company shall promptly
take all actions required  pursuant to such Section and Rule in order to fulfill
its  obligations  under this Section and shall include in the Schedule 14D-9, or

responsible  for any  information  with respect to Purchaser  and its  nominees,
officers, directors and affiliates required by Section 14(f) and Rule 14f-1.

Purchaser, on a timely basis, has the funds necessary to purchase the Shares.

          C. Takeover Statute. If any Takeover Statute becomes applicable to the
transactions  contemplated  hereby,  each of OS,  Purchaser and their respective
Board of Directors,  to the extent  reasonably  possible,  and  consistent  with

actions and execute and deliver such documents and  instruments as are necessary
so that the transactions  contemplated  hereby may be consummated as promptly as

                                  SECTION VIII

                   COVENANTS OF OS, PURCHASER AND THE COMPANY

          The parties hereto agree that:

          A.  Best  Efforts.  Subject  to  the  terms  and  conditions  of  this
Agreement,  each party will use its best efforts to take,  or cause to be taken,
all  actions  and to do, or cause to be done,  all things  necessary,  proper or
advisable under  applicable laws and regulations to consummate the  transactions
contemplated by this Agreement.

          B. Public  Announcements.  The initial press  release  relating to the

any

                                      -29-

<PAGE>

governmental authority  or  with  any  national securities exchange with respect
thereto,  unless in the opinion of the party  desiring to make such  disclosure,
such  disclosure is required by or consistent with applicable law or NASDAQ rule
or  regulation,  and in such event the party making the press  release or public
statement  shall provide a draft to the other party hereto and provide the other
party the  opportunity to comment thereon in a timely manner,  unless  emergency
circumstances preclude such procedure.

          C. Confidentiality. In the course of the discussions, negotiations and
due diligence conducted in furtherance of the transactions  contemplated hereby,
each party (on its own or through its agents) has and may  disclose to the other
certain   proprietary,   confidential   or   other   non-   public   information
(collectively,  the  "Information")  relating to its  respective  business,  the
proprietary,  confidential  and  non-public  nature  of which  information  both
parties desire to maintain.  Except as herein set forth, neither party shall (a)
reveal or make known to any person,  firm,  corporation or entity or (b) utilize
in its own business or (c) make any other usage of, any  Information  heretofore
or hereafter  disclosed to it by the other (on its own or through its agents) in
connection with the discussions, negotiations and due diligence activities above
mentioned.  A  party's  obligations  with  respect  to any  item of  Information
disclosed to it shall terminate if that item of Information becomes disclosed in
published  literature or otherwise  becomes  generally  available to the public;
provided,  however,  that such public  disclosure  did not  result,  directly or
indirectly,  from any act,  omission or fault of such party with respect to that
item of  Information.  Further,  this  paragraph  shall not apply to any item of
Information which at the time of disclosure was already  generally  available to
the public or which,  prior to July 26, 2000,  was already in the  possession of
the party  intending to utilize the item of Information  and was not acquired by
such party, directly or indirectly,  from the other party to this Agreement,  or
is required to be disclosed  under court order,  subpoena or other legal process
or disclosure  required  pursuant to applicable law. Both parties agree that the
Information  it either has  received or may receive  from the other has been and
will be used by the  receiving  party  solely  for the  limited  purpose  of its
investigation and evaluation of the other party in connection with the potential
Offer.

          Notwithstanding  this Section,  the Company  acknowledges  that OS has
disclosed and may need to disclose Information of the Company to the individuals
or entities  providing the financing to enable  Purchaser to purchase the Shares
and their  representatives as well as to governmental agencies under federal and
state securities laws and the Company hereby consents to the same; provided that
any such  disclosure  is  accompanied  by a copy of these  provisions  regarding
confidentiality  concerning the  transaction  contemplated  herein and the party
receiving  the  Information  agrees to abide by the terms  hereof.  The  Company
further agrees that OS can disclose such Information as OS, in consultation with
its counsel, determines it is necessary or appropriate to disclose in connection
with any filing  required  by the SEC,  including  the Offer  Documents  and any
filing  made  subsequent  thereto to advise the  shareholders  of the Company of
material  information  related to the Offer,  and any related  press  release in
connection with the transactions contemplated hereby. OS and the Purchaser agree
that the Company can disclose such Information and such information regarding OS
and Purchaser,  as the Company, in consultation with its counsel,  determines it
is necessary or appropriate to disclose in connection  with any filing  required
by the SEC, including the Offer Documents and any filing made subsequent thereto
to advise the shareholders of the Company of material information related to the
Offer,  and any  related  press  release  in  connection  with the  transactions
contemplated hereby.

things necessary, proper or appropriate under applicable laws and regulations to
consummate and make effective the  transactions  contemplated by this Agreement,
including but not limited to  cooperating in the  preparation  and filing of the
Offer  Documents,  the Schedule  14D-9 and any  amendments  to any thereof.  The
Company  shall use all  reasonable  efforts  to obtain  all  licenses,  permits,
consents, approvals,  authorizations,  qualifications and orders of governmental
authorities  and parties to contracts with the Company and the  Subsidiaries  as
are  necessary  for  the  Company  and  the   Subsidiaries   to  consummate  the

Offer. OS and Purchaser shall use all reasonable efforts to obtain all licenses,
permits,  consents,  approvals,  authorizations,  qualifications  and  orders of
governmental  authorities  and parties to contracts with OS and Purchaser as are
necessary for OS and Purchaser to consummate the  transactions  contemplated  by
this  Agreement.  Notwithstanding  anything  contained  herein to the  contrary,
Purchaser shall be under no obligation whatsoever to make or accept or engage in
negotiations  for any  settlement  with any  governmental  entity  or any  other
arrangement involving the sale,  disposition,  or separate holding,  through the
establishment of a trust, or otherwise,  of the business or any of the assets of
the Company or the  Subsidiaries  acquired  pursuant to this  Agreement,  or any
portion thereof,  or particular assets of Purchaser or its subsidiaries in order
to complete the transactions contemplated herein.

          (ii) The Company, on the one hand, and Purchaser and OS, on the other,
each  shall  keep the other  apprised  of the  status  of  matters  relating  to
completion  of  the  transactions   contemplated   hereby,   including  promptly
furnishing the other with copies of notices or other communications  received by
Purchaser,  OS or the Company, as the case may be, or any of their subsidiaries,
from any  governmental  entity  with  respect  to the  Offer or any of the other
transactions contemplated by this Agreement.

          E.  Directors' and Officers'  Insurance.  After the purchase of Shares
pursuant to the Offer,  the Company  shall  continue to maintain  the  Company's
existing  officers' and directors'  liability  insurance ("D&O Insurance") for a
period of three years,  provided,  however,  that (x) the Company may substitute
therefor  policies (which may be "tail" policies)  containing terms with respect
to  coverage  and  amount no less  favorable  in any  material  respect  to such
directors  and  officers,  and (y) if the existing  D&O  Insurance  expires,  is
terminated  or canceled  during such three- year  period,  the Company  will use
commercially reasonable efforts to obtain similar D&O Insurance.

          F.   Certain Compensation.  Notwithstanding anything in this Agreement
to  the contrary, the Company is permitted to pay up to $25,000 in the aggregate
to its  directors for services rendered in their active roles in connection with
the  negotiation  of  the  transactions contemplated by this Agreement, of which
$12,500 was paid prior to the date hereof.

          G. Bonus.  If the Net Worth and the Net Working Capital (as such terms
are defined  below) of the Company as of the end of the  Company's  fiscal month
immediately  preceding

                                      -31-
<PAGE>

the  month  during  which  the  Closing  occurs (the "Target Date") are equal to
or greater than $2,522,500 and $1,917,500  respectively  (the "Target Net Worth"
and "Target  Working  Capital") the Company shall pay to Daniel  Gorney,  Ronald
Spinelli and Thomas Archbold $10,000,  $15,000 and $10,000 respectively.  If the
Net Worth as of the Target Date exceeds the Target Net Worth and the Net Working
Capital as of the Target  Date  exceeds  the Target  Working  Capital  then,  in
addition to the amounts provided in the immediately preceding sentence,  Messrs.
Gorney, Spinelli and Archbold will each be paid 10% of the lesser of (x) the Net
Worth as of the Target  Date over the  Target Net Worth and (y) the Net  Working
Capital as of the Target Date over the Target Working Capital, up to the maximum
additional amount of $10,000 each. Notwithstanding the foregoing, and subject to
the following sentence, the bonuses paid under this Section to Messrs.  Archbold
and Spinelli will be a guaranteed  minimum of $5,000 each. The bonuses  provided
for in this  Section  will be  payable to any of Messrs.  Gorney,  Spinelli  and
Archbold  only if the  Closing  occurs  under  this  Agreement  and only if such
individual  is employed by the Company for at least  ninety days  following  the
purchase of the Shares (or is terminated  prior to such date without  cause) and
will be paid,  less applicable  withholding  taxes, no later than 120 days after
such date.

          For purposes of this agreement,  "Net Working  Capital" of the Company
as of the  Target  Date is  defined  as the  excess of the  inventory,  accounts
receivable and cash of the Company as of the Target Date over the trade accounts
payable,   accrued  payroll,   accrued  payroll  taxes  and  the  other  current
liabilities  of  the  Company  as of the  Target  Date.  For  purposes  of  this
Agreement,  the "Net  Worth" of the Company as of the Target Date shall mean the
excess of the total  assets of the  Company  over the total  liabilities  of the
Company, in each case as of the Target Date.

          The Net Worth and Net Working Capital of the Company shall be computed
by the Company's Chief Financial Officer and verified by Purchaser's accountants
in accordance with generally accepted  accounting  principles applied on a basis
consistent  with the past  practices  of the  Company,  except  as  specifically
provided herein.

          In  computing  the  Company's  Net Worth and Net Working  Capital,  no
accrual  shall be taken or amounts  otherwise  deducted for the bonuses  payable
pursuant to this Section or for the legal, accounting, printing, transfer agent,
fairness  opinion and other expenses  incurred by the Company in connection with
the transactions contemplated hereby.

accelerate  any  obligation of the Company  thereunder or which would  otherwise
constitute a default  thereunder by the Company provided,  the Company shall not
be  required to obtain the  consent of the other  party to any  agreement  which
provides  for receipt of or  repayment  by the  Company of less than  $12,500 or
which is set forth on the Company Disclosure Schedule;

          (viii) Except for the bonuses required pursuant to Section VIII.G., or

          (x) The  representations  and  warranties  made by the Company  herein
shall  have  been  correct  as of the date of this  Agreement,  except  for such
exceptions,  which  individually  or in the  aggregate,  would not  constitute a
material  breach of any  representation  or warranty  of the  Company  contained
herein. The  representations  and warranties made by the Company herein shall be
correct as of the Closing Date in all respects with the same force and effect as
though such representations and warranties had been made as of the Closing Date,
except for such exceptions  which,  individually or in the aggregate,  would not

                                   TERMINATION

          A.   Termination.  This Agreement  may be terminated and the Offer may
be abandoned at any time prior to the purchase of Shares pursuant thereto:

          (i)  by  mutual  written  consent of the Company and OS upon a vote of
their respective Boards of Directors;

          (ii) by either  the  Company or OS, if there  shall be any  applicable
domestic law, rule or regulation that makes consummation of the Offer illegal or
otherwise prohibited or if any judgment,  injunction, order or decree of a court
of competent  jurisdiction  shall restrain or prohibit the  consummation  of the
Offer,  and such  judgment,  injunction,  order or decree shall become final and
nonappealable;

          (iii) by Purchaser by action of the Board of Directors of Purchaser at
any time prior to the time Purchaser  purchases Shares pursuant to the Offer, if
(w) the Company shall have failed to comply in any material  respect with any of
the covenants or agreements  contained in this  Agreement to be complied with or
performed  by the Company,  and such failure  shall not have been cured prior to
the earlier of (A) five (5) business days following the giving of written notice
to the  Company  of such  failure or (B) the  business  day prior to the date on
which the Offer is then scheduled to expire, (x) the Board shall have amended or
modified in a manner adverse to Purchaser its approval or  recommendation of the
Offer,  shall have  withdrawn  such  recommendation  or shall have,  approved or
recommended any other Company Acquisition Proposal, or shall have resolved to do
any of the foregoing, or (y) the shareholders of the Company shall have tendered
less than  1,332,722  of the Shares or the  shareholders  which are party to the
Shareholders  Agreement shall have tendered in the aggregate less than 1,305,606
of their Shares in  accordance  with the  Shareholders  Agreement;  and, in each
case, OS and Purchaser are not in violation of Section IX. B(iv).

          (iv) by the  Company  by action of the Board at any time  prior to the
time Purchaser  purchases  Shares  pursuant to the Offer, if Purchaser (x) shall
have  failed to comply in any  material  respect  with any of the  covenants  or
agreements  contained  in this  Agreement  to be complied  with or  performed by
Purchaser,  and such  failure  shall not have been cured prior to the earlier of
(A) five (5) business days  following the giving of written  notice to Purchaser
of such  failure or (B) the business day prior to the date on which the Offer is
then  scheduled  to expire or (y) shall have failed to commence the Offer within
the time required in Section I.A. and the Company is not in violation of Section

                                      -35-
<PAGE>

          (v) by the  Company by action of the Board,  if the Board  receives or
there is publicly  announced a bona fide written  Company  Acquisition  Proposal
(which Company Acquisition Proposal was unsolicited and did not otherwise result
from a breach of Section  V.C.) and the Board  determines in good faith (i) that
such Company  Acquisition  Proposal is reasonably  likely,  if  consummated,  to
result in a  transaction  more  favorable to the Company's  shareholders  from a
financial point of view than the  transaction  contemplated by this Agreement (a
"Superior  Proposal") and (ii) after  consultation  with outside  counsel,  that
approval,  acceptance or recommendation of such Company Acquisition  Proposal or
tender or exchange  offer is necessary in order for its directors to comply with
their  respective   fiduciary  duties,  and  the  Company  shall   substantially
concurrently with such termination enter into a definitive  agreement containing
the terms of a Superior Proposal;  provided, however, that the Company shall not
exercise its right to terminate this Agreement  pursuant to this Section X.A.(v)
until after three (3) days  following  Purchaser's  receipt of written notice (a
"Notice of Superior  Proposal")  from the Company  advising  Purchaser  that the
Company's Board of Directors has received a Superior  Proposal (or that a tender
or exchange  offer with respect to the Shares has been  commenced)  and that the
Board will,  subject to any action taken by Purchaser pursuant to this sentence,
cause the Company to accept such Superior  Proposal (or recommend such tender or
exchange  offer),  and  specifying  the  material  terms and  conditions  of the
Superior  Proposal and identifying the person making such Superior  Proposal (it
being  understood  and  agreed  that any  amendment  to the  price or any  other
material  term of a Superior  Proposal  shall  require an  additional  Notice of
Superior Proposal and a new three day period).

          (vi) by either  the  Company  or OS if the  Offer  shall not have been
consummated  by March 31,  2001  (other  than  through  the failure of the party
seeking termination to comply with its obligations under this Agreement).

          B.   Effect of Termination.

          If this  Agreement is  terminated  pursuant to Article  X.A., no party
hereto (or any of its directors or officers) shall have any liability or further
obligation  to any other  party to this  Agreement,  except as  provided in this
Section X.B and Section XI below.

          (i) If this Agreement  shall be terminated by the Company  pursuant to
Section X. A. (v), then the Company shall  promptly,  but in no event later than
ten days after receipt of a statement,  reimburse Purchaser's  reasonable out of
pocket costs and expenses  actually  incurred in connection  with this Agreement
and the transactions contemplated hereby.

          (ii) If (X) the Purchaser shall  terminate this Agreement  pursuant to
clause (x) of Section  X.A.(iii),  or the  Company  shall have  terminated  this
Agreement  when it did not  have a right  to do so  under  Section  X.A.,  then,
notwithstanding the fact that grounds may also exist to terminate this Agreement
under clause (w) or (y) of Section X.A. (iii),  the Company shall promptly,  but
in no  event  later  than ten  days  after  receipt  of a  statement,  reimburse
Purchaser's  reasonable  out-of-pocket  costs and expenses  actually incurred in
connection with this Agreement and the transactions contemplated hereby; and (Y)
the Purchaser  shall  terminate this Agreement  pursuant to clause (w) or (y) of
Sections X.A. (iii), then the Company shall promptly, but in no event later than
ten  days  after  receipt  of  a  statement,  reimburse  Purchaser's  reasonable
out-of-pocket  expenses  actually incurred in connection with this Agreement and
the transactions  contemplated hereby up to a

                                      -36-

<PAGE>

maximum  of  $325,000,  of  which  the  first $250,000 would be paid in cash and
the excess over $250,000 paid in Shares valued at $1.525 per share.

          (iii) If the  Company  shall  terminate  this  Agreement  pursuant  to
Section X.A.(iv),  or the Purchaser shall have terminated this Agreement when it
did not have a right to do so under Section X.A., then Purchaser shall promptly,
but in no event later than ten days after receipt of a statement,  reimburse the
Company's  reasonable  out-of-pocket  costs and  expenses  actually  incurred in
connection with this Agreement and the transactions  contemplated hereby up to a
maximum of $150,000.

          The  parties  agree that the  amounts  provided  for in the  preceding
clauses (i)  through  (iii)  constitute  a fair and  reasonable  estimate of the
damages  to the  intended  recipient  thereof  resulting  from  the  failure  to
consummate  the Offer and that upon  payment of the  specified  amount,  neither
party shall have any further  liability to the others under this Agreement or in
connection with the transactions contemplated hereby.

          Each of the parties acknowledges that the agreements contained in this
Section to reimburse  the other for its  expenses  are an integral  part of this
Agreement and that without these agreements neither would have entered into this
Agreement.  Accordingly,  if either  party fails to promptly  pay the amount due
pursuant to clauses (i) through  (iii) of this  Section  and, in order to obtain
payment the aggrieved party commences a suit which results in a judgment against
the defaulting  party for the fee provided above, the defaulting party shall pay
to the aggrieved party its costs and expenses (including  reasonable  attorneys'
fees) in  connection  with such suit and  interest on the amount due at the base
rate of Citibank, N.A. on the date such payment was required to be made.

                                   SECTION XI

          B. Survival  of  Representations. The  covenants and agreements of the
parties  contained  in  Sections  VIII.C.,  VIII.E., VIII.F,  VIII.G, X.B and XI
shall  survive  the  purchase  of  Shares  pursuant  to the  Offer or any  other
termination  of  this  Agreement.  All  other  representations,  warranties  and
agreements  contained  herein and in any certificate or other writing  delivered
pursuant hereto shall not survive the purchase of the Shares in the Offer.

          C.   Expenses.  Except  as  otherwise  provided  herein,  each  of the
parties hereto shall bear such party's  own  expenses  in  connection  with this
Agreement and the transactions contemplated hereby.

          D.  Invalidity.  Should any  provision of this  Agreement be held by a
court of competent jurisdiction to be enforceable only if modified, such holding
shall not affect the validity of the remainder of this Agreement, the balance of
which  shall  continue  to be  binding  upon the  parties  hereto  with any such
modification to become a part hereof and treated as though  originally set forth
in this  Agreement.  The parties  further agree that any such court is expressly
authorized to modify any such unenforceable  provision of this Agreement in lieu
of severing such  unenforceable  provision  from this Agreement in its entirety,
whether  by  rewriting  the  offending  provision,  deleting  any  or all of the
offending provision,  adding additional language to this Agreement, or by making
such  other  modifications  as it deems  warranted  to carry out the  intent and
agreement of the parties as embodied  herein to the maximum extent  permitted by
law. The parties  expressly  agree that this  Agreement as modified by the court
shall be binding upon and enforceable against each of them. In any event, should
one or more of the provisions of this  Agreement be held to be invalid,  illegal
or unenforceable in any respect, such invalidity, illegality or unenforceability
shall  not  affect  any  other  provisions  hereof,  and if  such  provision  or
provisions are not modified as provided above, this Agreement shall be construed
as if such invalid, illegal or unenforceable provisions had never been set forth
herein.

          E. Successors and Assigns. Purchaser shall have the right, at Closing,
to assign the right to  purchase  the  Shares,  in whole or in part,  to another
entity controlled by OS or to any of the shareholders of OS or related investors
which have  committed  to fund  Purchaser  (or  designees  thereof)  as noted in
Section IV.H,  provided that no such  assignment  shall relieve  Purchaser or OS
from any of its  obligations  hereunder.  Such  designees  shall at the  Closing
deliver  affirmative  representations  as  to  their  organization,   authority,
capacity,  and lack of  conflicts  in  purchasing  the  Shares.  Subject  to the
limitations of the first  sentence of this  paragraph,  this Agreement  shall be
binding  upon and inure to the  benefit  of the  successors  and  assigns of the
Company, Purchaser and OS, respectively.

          F.   Governing Law.   The validity of this Agreement and of any of its
terms or provisions, as well as the  rights and duties of the parties under this
Agreement, shall be governed by and construed pursuant to and in accordance with
the  laws  of  the  State  of  New  York, without regard to its conflict of laws
principles.

          G.   Counterparts.   This  Agreement  may be executed in counterparts,
each of which shall be deemed an original, but all of which taken together shall
constitute one and the same instrument.

          H. Entire  Agreement;  Amendments.  This  Agreement  and the documents
referred  to herein  constitute  the entire  agreement  among the  parties  with
respect to the subject  matter  hereof.  Any provision of this  Agreement may be
amended or waived prior to the purchase of Shares  pursuant to the Offer if, and
only if, such  amendment  or waiver is in writing and signed,  in the case of an

agreement or understanding in writing with the Company providing for termination
or amendment of the Offer or delay in payment for the Shares;

which in the  reasonable  judgment  of  Purchaser,  in any such  case,  makes it
inadvisable to proceed with the Offer and/or with such acceptance for payment of
or payment for Shares.

          The foregoing conditions are for the sole benefit of Purchaser and may
be asserted by Purchaser  regardless  of the  circumstances  giving rise to such
condition or may be waived by Purchaser,  by express and specific action to that
effect,  in  whole  or in part at any  time  and  from  time to time in its sole
discretion.

          The failure by Purchaser at any time to exercise any of the  foregoing
rights  shall not be deemed a waiver of any such  right,  the waiver of any such
right with  respect to  particular  facts and other  circumstances  shall not be
deemed a waiver with respect to any other facts and circumstances, and each such
right shall be deemed an ongoing right that may be asserted at any time and from
time to time.

<PAGE>

          4.   Representations and Warranties of OS and Purchaser.  Each of OS
and Purchaser hereby represents and warrants to each Shareholder and the Company
as follows:

               (a) Organization.  Each of OS and Purchaser is a corporation duly
organized, validly existing and in good standing under the laws of the State of
New York and has full corporate power and authority to own its properties and to
conduct the businesses in which it is now engaged.

               (b) Authority.  Each of OS and Purchaser has all requisite  power
and authority to enter into this Agreement and the transactions contemplated
hereby and to perform its obligations pursuant to the terms of this Agreement.
The execution, delivery and performance of this Agreement by OS and Purchaser,
and the consummation of the transactions contemplated hereby, have been duly
authorized by all necessary action on the part of OS and Purchaser. This
Agreement has been duly executed and delivered by OS and Purchaser and
constitutes a valid and binding obligation of each of OS and Purchaser
enforceable against OS and Purchaser in accordance with its terms, except that

affecting creditors rights generally. Except for informational filings with the
SEC, the execution and delivery of this Agreement do not, and the consummation
of the transactions contemplated hereby and compliance with the terms hereof
will not, (i) conflict with, or result in any violation of, or default (with or
without notice or lapse of time or both) under, any provision of, any loan or
credit agreement, note, bond, mortgage, indenture, lease or other agreement,

this Agreement by OS and Purchaser or the performance by OS and Purchaser of
their obligations hereunder.

             (d) Investment  Intent.  The Purchaser is acquiring those Subject
Shares that bear a restrictive legend for investment and not with a view toward,
or for sale in connection with, any distribution thereof, nor with any present
intention of distributing or selling the Subject Shares. Purchaser acknowledges
that certain of the Subject Shares bear restrictive legends as identified on
Exhibit A and may be "restricted stock" and are accordingly being acquired
pursuant to the so-called 4(1-1/2)exemption, or other applicable exemption, from
the Securities Act of 1933, as amended. Nothing in this Agreement is intended to
or shall restrict the Purchaser's right to sell or transfer the Subject Shares
subsequent to the Purchaser's acquisition thereof, subject to compliance with
applicable securities laws.

<PAGE>

             (e) Sophistication.  The principals of Purchaser and OS have such
knowledge and experience in financial and business matters, and in particular in
investments in companies in the industry in which the Company operates, to
enable them to make an informed decision with respect to the acquisition of the
Subject Shares. Such principals have received copies of the Company's filings
with the Securities and Exchange Commission within the past 12 months and have
seen and reviewed the Offer Agreement, including the Schedules thereto.

          5.   Covenants of Each Shareholder.  Until the termination of this
Agreement in accordance with Section 14, each Shareholder, severally and not
jointly, agrees as follows:

               (a) At any  meeting  of  Shareholders  of the  Company  or at any
adjournment thereof or in any other circumstances upon which the Shareholder's
vote, consent or other approval is sought under applicable law, the Shareholder
shall, or shall cause the record holder of his or its Subject Shares to, vote
(or cause to be voted) his or its Subject Shares (and each class thereof)
against (i) any amendment of the Company's Certificate of Incorporation or
by-laws, which amendment would be reasonably likely to impede, frustrate,
prevent or nullify the Offer or any of the other transactions contemplated by
the Offer Agreement or change in any manner the voting rights of any class of
Company Common Stock, (ii) any action that would cause the Company to breach any
representation, warranty or covenant contained in the Offer Agreement or (iii)
any action to elect to the Company's Board of Directors anyone other than the
designees of Purchaser or replacements of existing Directors, which replacement
Directors agree to resign on the Closing of the Offer.

               (b) The Shareholder  shall not, except as contemplated by Section
1 and Section 6 hereof or with the written consent of OS or Purchaser, during
the period commencing as of the date hereof and ending on the earlier of (i) the
purchase of Subject Shares pursuant to Section 1 or Section 6 hereof and (ii)
March 31, 2001, (A) sell, transfer, give, pledge, assign or otherwise dispose of
(including by gift) (collectively, "Transfer"), or consent to any Transfer of,
any or all of such Subject Shares or Options or any interest therein or enter
into any contract, option or other arrangement (including any profit sharing
arrangement) with respect to the Transfer of the Subject Shares or Options to
any person or (B) enter into any voting arrangement, directly or indirectly,
whether by proxy, voting agreement or otherwise, in respect of the Subject
Shares and shares issuable upon exercise of the Options, and the Shareholder
agrees not to commit or agree to take any of the foregoing actions. Any transfer
or attempted transfer of Subject Shares in violation of this Agreement shall be
void and of no force and effect.

          6.   Transfer to Purchaser.

               (a) Each Shareholder agrees that if the Offer is not completed or
is terminated in each case due to the receipt by the Company or its shareholders
of a Company Acquisition Proposal at a higher price per share than the initial
Offer Price of $1.525 per share, then upon the Purchaser's election at any time
within the Purchase Period set forth in this Section 6, such Shareholder shall
sell all, but not less than all, of his or its Subject Shares to Purchaser at
$1.525 per share.

                                      -5-
<PAGE>

          Purchaser  shall send notice of its  election to purchase  the Subject
Shares of each Shareholder (the "Purchase Notice") no later than 11:59 P.M.
March 31, 2001 (the "Purchase Period"). The Purchase Notice shall specify a time
(the "Closing Date") and place for the transfer of each Shareholder's Subject
Shares which shall not be less than five (5) or more than twenty (20) days after
the date of the Purchase Notice. At closing, Purchaser shall pay to each
Shareholder the aggregate purchase price for his or its Subject Shares, by bank
check or wire transfer of immediately available funds to accounts designated by
each Shareholder no later than two days prior to the Closing Date, against
delivery of the stock certificates representing the Subject Shares duly endorsed
or accompanied by stock powers duly endorsed in blank with signatures medallion
guaranteed. All Subject Shares shall be delivered free and clear of any and all
liens, claims, encumbrances or restrictions. The obligation of each Shareholder
to transfer the Subject Shares to Purchaser pursuant to this Section 6 shall
continue in full force and effect during the Purchase Period despite the
existence of a Company Acquisition Proposal.

             (b) Each Shareholder agrees that such Shareholder will deliver to
the Company, immediately after the execution hereof (or, in the event Subject
Shares are acquired by a Shareholder subsequent to the date hereof, immediately
after such acquisition), any and all certificates representing such
Shareholder's Subject Shares in order that the Company may inscribe upon such
certificates a legend confirming the Agreements contained herein. Upon receipt
of such certificates the Company shall promptly inscribe the legend on
certificates representing such Subject Shares, and deliver the same to such
Shareholder, who will immediately thereafter or, if later, promptly upon
commencement of the Offer, tender the same to the Depositary Agent engaged by
Purchaser to facilitate the Offer.

          7. Covenants of the Company.  Until the  termination of this Agreement
in accordance with Section 14, the Company agrees not to permit any transfer of
Subject Shares in violation of this Agreement to be recorded on its books and
records and, concurrently herewith shall so direct its transfer agent and all
parties hereto acknowledge such direction.

          8. Further Assurances. Each Shareholder will from time to time,
execute and deliver, or cause to be executed and delivered, such additional or
further consents, documents and other instruments as Purchaser may reasonably
request for the purpose of effectively carrying out the transactions
contemplated by this Agreement.

          9. Successors;  Recapitalizations.  Each Shareholder  agrees that this
Agreement and the obligations hereunder shall attach to such Shareholder's
Subject Shares and shall be binding upon any person or entity to which legal or
beneficial ownership of such Subject Shares shall pass, whether by operation of
law or otherwise, including without limitation such Shareholder's heirs,
guardians, administrators or successors. In the event of any stock split, stock
dividend, merger, reorganization, recapitalization or other change in the
capital structure of the Company affecting the Company Common Stock, or the
acquisition of additional shares of Company Common Stock or other voting
securities of the Company by any Shareholder, the number of Subject Shares
listed in Exhibit A beside the name of such Shareholder shall be adjusted
appropriately and this Agreement and the obligations hereunder shall attach to
any additional shares of Company Common Stock or other voting securities of the
Company issued to or acquired by such Shareholder.

Altholz and Daniel J. Gorney (the "Option Sellers") agrees not to exercise any
of his Options prior to the earlier of March 31, 2001 or the purchase of Shares

agrees effective upon the purchase of Shares pursuant to the Offer or Section 6
hereof, to sell and transfer to the Company for the amount set forth opposite
his name on Exhibit A hereto, all right, title and interest he may have to
purchase or acquire any shares of Company Common Stock, including the options or
warrants ascribed to him on Exhibit A hereto.

          11. Release.  On the Closing Date, each Shareholder  shall execute and
deliver a release in favor of the Company of any and all claims which such
Shareholder may have or had against or with respect to the Company, its
successors or assigns, in his or its capacity as a Shareholder of the Company,
by virtue of any matter, cause or thing arising prior to the Closing Date.

          12.  Assignment.  Neither  this  Agreement  nor  any  of  the  rights,
interests or obligations hereunder shall be assigned by any party or parties
without the prior written consent of all the other parties, except that (i)
Purchaser may assign, in its sole discretion, in whole or in part, any or all of
its rights, interests and obligations hereunder to any shareholder of OS which
has committed to fund Purchaser for purposes of the Offer Agreement and any
subsidiary of OS that may be substituted for Purchaser as contemplated by the
Offer Agreement, and (ii) OS may assign, in its sole discretion, any and all of
its rights, interests and obligations hereunder to any direct or indirect wholly
owned subsidiary of OS, provided that OS will continue to remain primarily
liable for its obligations hereunder in the event of any assignment pursuant to
this clause (ii). Subject to the preceding sentence, this Agreement will be
binding upon, inure to the benefit of and be enforceable by the parties and
their respective successors and permitted assigns.

          13.  Conditions.  The obligations of OS and Purchaser to purchase and
the obligations of each Shareholder to sell the Subject Shares pursuant to
Section 1 of this Agreement shall be subject to the prior satisfaction or waiver
of the following conditions:

               (a)  Purchaser shall have accepted the Subject Shares for payment
under the terms of the Offer;

               (b)  the Minimum Condition shall have been satisfied;

               (c) all  regulatory  approvals  required by any  applicable  law,
rule, or regulation,  including any applicable local, state,  federal or foreign
regulation, shall have been obtained, and each such approval shall be final;

               (d)  all conditions to the obligations of OS and Purchaser under
the Offer Agreement shall have been satisfied; and

               (e) there shall exist no preliminary or permanent injunction,  or
any order by the SEC, any state securities agency, or any court of competent
jurisdiction, delaying, restricting, preventing or prohibiting the purchase or
delivery of the Subject Shares.

                                      -7-
<PAGE>

          14.  Termination.  If Purchaser has not  purchased the Subject  Shares
pursuant to the Offer and if Purchaser has not sent the Purchase Notice, prior
to the end of the Purchase Period, then at the end of the Purchase Period this
Agreement shall terminate without any liability hereunder on the part of
Purchaser or any Shareholder, unless the failure of Purchaser to purchase the
Subject Shares was caused by a breach of this Agreement by any Shareholder, OS
or Purchaser, in which event the non-breaching party shall have the right to
seek such remedies as may be available to it at law or in equity; provided,
however, that Sections 14, 15 and 18 hereof shall survive any termination of
this Agreement.

          15.  General Provisions.

             (d)  Counterparts.  This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement, and

each of the parties and delivered to the other party, it being understood that
each party need not sign the same counterpart.

             (e)  Entire  Agreement;   No  Third-Party   Beneficiaries.   This
Agreement (including the documents and instruments referred to herein) (i)
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof and (ii) is not intended to confer upon any person other
than the parties hereto and their respective successors and assigns any rights
or remedies hereunder.

             (f) Governing  Law. This  Agreement  shall be governed by, and
construed in accordance with, the laws of the State of New York, without
giving effect to its conflicts of laws rules.

             (g)  Survival.   The   representations  and  warranties  of  each
Shareholder, the Company, OS and Purchaser contained herein, each as of the date
hereof and as of the Closing Date, as to his or its organization, authority to
enter into this Agreement, ownership of his or its Subject Shares, and brokers'
fees shall survive the delivery and sale of the Subject Shares pursuant to the
terms hereof.

             (h)  Expenses.  Each of the parties  hereto shall bear his or its
own expenses in connection with the execution,  delivery and performance of this
Agreement and the transactions contemplated hereby.

          16. Shareholder Capacity. No person executing this Agreement who is or
becomes during the term hereof a director or officer of the Company makes any
agreement or understanding herein in his capacity as such director or officer.
Each Shareholder signs solely in his capacity as the record or beneficial owner
of, or the trustee of a trust whose beneficiaries are the beneficial owners of,
such Shareholder's Subject Shares and nothing herein (including, without
limitation, the provisions of Section 5) shall limit or affect any actions taken
by a Shareholder in his capacity as an officer or director of the Company.

          17.  Exculpation.  Notwithstanding  any provision of this Agreement or
the Offer Agreement to the contrary, no action of any Shareholder who is a
director of the Company (a "Director") taken in his capacity as a Director,
shall be, or be deemed to be, a breach of any provision of this Agreement if
such action is taken by the Director, in his sole discretion, in the performance
of his fiduciary or any other duty as a Director, in the best interests of the
Company or its shareholders or to comply with applicable law and regulations.

          18. Enforcement. The parties agree that irreparable damage would occur
in the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any court of the United States
located in the State of New

York or in a New York state court, this being in addition to any other
remedy to which they are entitled at law or in equity. In addition, each of the
parties hereto (i) consents to submit such party to the personal jurisdiction of
any Federal court located in the State of New York or any New York state court
in the event any dispute arises out of this Agreement or any of the transactions
contemplated hereby, (ii) agrees that such party will not attempt to deny or
defeat such personal jurisdiction by motion or other request for leave from any
such court, (iii) agrees that such party will not bring any action relating to
this Agreement or the transactions contemplated hereby in any court other than a
Federal court sitting in the State of New York or a New York state court and
(iv) waives any right to trial by jury with respect to any claim or proceeding
related to or arising out of this Agreement or any of the transactions
contemplated hereby.

          19. Public Announcements. No Shareholder shall issue any press release
or make any public statement with respect to this Agreement and the purchase of
its or his Subject Shares hereby, without the prior written consent of OS, which
may not be unreasonably withheld, except as may be required by applicable law,
the regulations of the SEC, court process or by obligations pursuant to any
listing agreement with any national securities exchange; provided that in such
case such Shareholder shall provide a copy of the proposed release in advance to
OS and provide OS with an opportunity to comment thereon in a timely manner,
unless emergency circumstances preclude such procedure. This restriction does
not extend to such press releases as the Shareholders, in their capacities as
officers and directors of the Company, may determine to issue in connection with
the Offer.

          20. Confidential Information.  Each Shareholder,  individually and not
jointly, covenants and agrees that from and after the purchase of such
Shareholder's Shares pursuant to Section 1 or Section 6 hereof, such Shareholder
shall keep secret all non-public Confidential Information (as defined below) of
the Company and not to disclose it to anyone outside the Company or use it for
their own account or the account of others without the Company's prior written
consent except for such Confidential Information which:

          (1) is or becomes generally available to the public through no act on
the part of such Shareholder;

          (2) is or becomes  available on a  non-confidential  basis from a
party that is not  subject to an  obligation  of  confidentiality  with  respect
thereto; or

          (3)  is  required to be disclosed pursuant to subpoena, court order or
applicable law.

"Confidential Information" shall include proprietary information about the
Company's business, products, costs, profits, finances, internal financial
statements and projections, markets, sales, customers, vendors, personnel,
pricing policies, operational methods, technical processes and methods, plans
for future developments, specifications, trade secrets, technology, know-how,
research and development. This Section 20 shall survive and continue in effect
from and after the purchase of Shares pursuant to Section 1 or Section 6 hereof.
