     of the Company or any Subsidiary (i.e., a "poison pill"); or

          (iii) enter into any transaction with any of its officers,  directors,
     employees or Affiliates or any  individual  related by blood or marriage to

after the Closing relating to the other party, this Agreement,  the Stockholders
Agreement,  the  Stock  Purchase  Warrant  or  the  consummation  of  any of the
transactions  contemplated by this Agreement,  the Stockholders Agreement or the
Stock Purchase  Warrant  (including  any exercise of a Stock  Purchase  Warrant)
without  the  prior  consent  of the other  party,  which  consent  shall not be
unreasonably  withheld. The text of any such public announcement which any party

him if the Company is at the time or had been within the  preceding two years in
default of its obligations under Section 4A(i)(c), 4A(i)(d) or 4A(i)(e) and such
default in the case of Section  4A(i)(c) or 4A(i)(d) remains or remained uncured
for 20  business  days and in the case of Section  4A(i)(e)  remains or remained
uncured for 5 business days.

     4F.  Confidentiality.  Purchaser will treat and hold as confidential all of
the  Confidential  Information,  refrain  from  using  any of  the  Confidential
Information  except in  connection  with  this  Agreement,  the  Stock  Purchase
Agreement,  the Stock  Purchase  Warrant,  the  Stockholders  Agreement  and the
Purchaser's  ownership of Common Stock  hereunder and  thereunder.  In the event
that  Purchaser  is  requested  or  required  (by oral  question  or request for
information or documents in any legal proceeding, interrogatory, subpoena, civil
investigative   demand,   or  similar  process)  to  disclose  any  Confidential
Information,  Purchaser  will  notify the  Company  promptly  of the  request or
requirement so that such Stockholder may seek an appropriate protective order or
waive compliance with the provisions of this Section 4F. If, in the absence of a
protective  order or the  receipt of a waiver  hereunder,  Purchaser  is, on the
advice of counsel,  compelled to disclose any  Confidential  Information  to any
tribunal  or  else  stand  liable  for  contempt,  Purchaser  may  disclose  the
Confidential  Information  to the tribunal;  provided,  however,  that Purchaser
shall use  reasonable  efforts  to obtain,  at the  request  and  expense of the
Company,  an  order or  other  assurance  that  confidential  treatment  will be
accorded  to  such  portion  of  the  Confidential  Information  required  to be
disclosed  as the  Company.  The  foregoing  provisions  shall  not apply to any
Confidential  Information that is generally  available to the public immediately
prior  to  the  time  of  disclosure.  Notwithstanding  anything  herein  to the
contrary,  Purchaser  may  provide  Confidential  Information  to any  Person if
Purchaser  deems  necessary  or  desirable  in  connection  with any transfer or
proposed  transfer of  Purchaser's  Common  Stock so long as such  Persons  have
entered into  appropriate  confidentiality  arrangements  with Purchaser  (which
shall name the Company as an intended beneficiary).






     4G. Filings.  The Company and Purchaser shall make all filings  required to
be made with the SEC, any stock exchange in which the Common Stock is listed and
all other  governmental  or  quasi-governmental  entities in connection with the
consummation of the transactions  contemplated hereby and under the Stockholders
Agreement  and  the  Stock  Purchase  Warrant.  All  such  filings  shall  be in
compliance with all applicable  laws,  regulations,  rules and ordinances of all
applicable stock exchanges and governmental and  quasi-governmental  entities in

Person  within two years after the date on which the Board of  Directors  of the
Company voted on such acquisition, merger, consolidation or other transaction.

consent  of the  board  of  directors  of the  Company  or  any  Subsidiary,  as

     Company's and the Subsidiaries'  expenditures for any fiscal year to exceed
     by more  than  10% the  amount  set  forth  for  capital  expenditures  for

     stock purchase, asset purchase, merger,  recapitalization,  share exchange,
     consolidation  or other  transaction)  or make an investment in any Person;
     provided that Company or any  Subsidiary  may acquire (via stock  purchase,

     Board of Directors of the Company in its reasonable good faith judgment) in
     any transaction or series of related transactions.

     Section 5..  Representations  and Warranties of the Company.  As a material
inducement  to  Purchaser to enter into this  Agreement  and purchase the Shares
hereunder,  the Company hereby  represents and warrants as of the date hereof as
follows:






     5A.  Organization,   Corporate  Power  and  Licenses.   The  Company  is  a
corporation duly organized, validly existing and in good standing under the laws
of Delaware and is qualified to do business in every  jurisdiction  in which its
ownership  of  property or conduct of  business  requires it to qualify,  except
where the failure to so qualify would not have a Material  Adverse  Effect.  The
Company  possesses all requisite  corporate power and authority and all material
licenses,   permits  and  authorizations   necessary  to  own  and  operate  its
properties,  to  carry  on its  businesses  as now  conducted  and as  presently
proposed to be conducted and to carry out the transactions  contemplated by this
Agreement, the Stockholders Agreement and the Stock Purchase Warrant.

     5B. Capitalization and Related Matters.

     (i)......As of immediately before the Closing, the authorized capital stock
of the Company shall consist of: (x) 2,000,000 shares of Preferred  Stock,  $.01
per share par value,  of which zero shares are issued and  outstanding,  and (y)
25,000,000  shares of Common Stock, $.01 per share par value, of which 6,348,603
shares are issued and outstanding. As of immediately before the Closing, neither
the  Company  nor any  Subsidiary  shall have  outstanding  any  capital  stock,
options,  convertible  securities,  securities or rights  containing  any profit
participation  features,  or any stock appreciation right or phantom stock plan,
except as set forth on Section 5B of the  Disclosure  Schedule  attached  hereto
(the "Disclosure  Schedule").  Section 5B of the Disclosure  Schedule accurately
sets forth the following information with respect to all outstanding options and
rights to acquire the Company's and the Subsidiaries' capital stock: the holder,
the number of shares covered,  the exercise price and the expiration date. As of
immediately before the Closing,  neither the Company nor any Subsidiary shall be
subject to any  obligation  (contingent or otherwise) to repurchase or otherwise
acquire or retire any shares of its capital  stock or any  warrants,  options or
other rights to acquire its capital stock,  except as set forth on Section 5B of
the Disclosure Schedule. As of the Closing, all of the outstanding shares of the
Company's capital stock shall be validly issued, fully paid and nonassessable.

     (ii).....There are no statutory or, to the Company's Knowledge, contractual
stockholders'  preemptive  rights or  rights  of  refusal  with  respect  to the
issuance of the Shares. Assuming Purchaser's  representations and warranties set
forth in Section 6 are true and correct as of the date  hereof,  the Company has
not violated any applicable  federal or state securities laws in connection with
the offer, sale or issuance of any of its capital stock, and the offer, sale and
issuance of the Shares do not require  registration  under the Securities Act or
any applicable state securities laws. To the Company's Knowledge, other than the
Stockholders  Agreement and the Stock Purchase Warrant,  there are no agreements
between the Company's shareholders with respect to the voting or transfer of the
Company's  capital  stock or with respect to any other  aspect of the  Company's
affairs.






     5C.  Subsidiaries.  Section 5C of the  Disclosure  Schedule  correctly sets
forth the name of each  Subsidiary,  the  jurisdiction of its  incorporation  or
under which it was formed and the Persons owning the  outstanding  securities of
such Subsidiary. Each Subsidiary is duly organized, validly existing and in good
standing under the laws of the jurisdiction under which it was formed, possesses
all  requisite  power and  authority  and all  material  licenses,  permits  and
authorizations necessary to own its properties and to carry on its businesses as
now being conducted and as presently proposed to be conducted in the future, and
is  qualified  to do business in every  jurisdiction  in which its  ownership of
property or conduct of business  requires it to qualify except where the failure
to so qualify would not have a Material  Adverse Effect.  All of the outstanding
securities of a Subsidiary which are owned by the Company or another  Subsidiary
are owned free and clear of any Lien and are not  subject to any option or right
to purchase any such shares. Except as set forth in Section 5C of the Disclosure
Schedule,  neither  the Company  nor any  Subsidiary  owns or holds the right to
acquire  any  shares of stock or any other  security  or  interest  in any other
Person.

     5D.  Authorization;  No Breach. The execution,  delivery and performance of
this Agreement, the Stockholders Agreement and the Stock Purchase Warrant by the
Company have been duly authorized by the Company.  Each of this  Agreement,  the
Stockholders  Agreement and the Stock Purchase  Warrant,  when it is executed by
the other parties thereto, will constitute a valid and binding obligation of the
Company enforceable in accordance with its respective terms except to the extent
that the  enforceability  thereof may be limited by  bankruptcy,  insolvency  or
similar laws of general application  relating to or affecting the enforcement of
creditors'  rights or by general  principles  of equity.  Except as set forth in
Section 5D of the Disclosure Schedule, the execution and delivery by the Company
of this Agreement,  the Stockholders  Agreement and the Stock Purchase  Warrant,
the offering,  sale and issuance of the Shares  hereunder and the fulfillment of
and compliance  with the  respective  terms hereof and thereof by the Company do
not and  shall  not (i)  conflict  with or  result  in a  breach  of the  terms,
conditions or provisions of, (ii)  constitute a default  under,  (iii) result in
the creation of any Lien upon the Company's or any  Subsidiaries'  securities or
assets pursuant to, (iv) give any third party the right to modify,  terminate or
accelerate any obligation  under,  (v) result in a violation of, or (vi) require
any authorization,  consent, approval, exemption or other action by or notice or
declaration to, or filing with, any court or administrative or governmental body
or  agency  pursuant  to,  (A) the  Charter,  the  By-Laws  or the  constituting
documents of any Subsidiary,  (B) any law, statute,  rule or regulation to which
the Company or any  Subsidiary  is subject,  or (C) any  material  agreement  or
instrument,  or any  order,  judgment  or  decree to which  the  Company  or any
Subsidiary  is  subject,  except in the case of (B) and (C) were such  conflict,
default or violation would not have a Material Adverse Effect.

     5E. SEC  Documents  and Financial  Statements.  The Company has  heretofore
delivered to Purchaser each of the
following:

          (i)  Annual  Report of the  Company on Form 10-K as filed with the SEC
     for the Company's fiscal year ended March 31, 1998; and

          (ii)  Quarterly  Report of the  Company on Form 10-Q as filed with the
     SEC for the fiscal quarter of the Company ended June 30, 1998.

filed with the SEC,  and except as set forth on  Schedule  5E of the  Disclosure
Schedule or a subsequent SEC Report,  do not as of the date hereof,  contain any
untrue  statement of a material fact or omit to state a material fact  necessary
in order to make the statements  therein,  in light of the  circumstances  under
which they were made, or are now made, respectively,  not misleading. All of the
financial  statements  contained  in the  SEC  Reports  have  been  prepared  in
accordance  with GAAP  applied on a  consistent  basis  throughout  the  periods
covered thereby,  fairly present in all material respects the financial position
of the  Company  and the  Subsidiaries  as of such  dates  and  the  results  of
operations and cash flows of the Company and the  Subsidiaries for such periods,
and  are  consistent  with  the  books  and  records  of  the  Company  and  the
Subsidiaries;  provided,  however, that the Most Recent Financial Statements are
subject to normal  year-end  adjustments  (none of which could,  alone or in the
aggregate,  reasonably be expected to have a Material  Adverse  Effect) and lack
footnotes and other presentation items.

     5F.  Reports with the SEC. The Company and the  Subsidiaries  have made all
filing  with  the  SEC  which  they  are  required  to make  (including  without
limitation all required  filings under the Securities Act and the Exchange Act),
and  have not  received  any  request  from  the SEC to file  any  amendment  or
supplement  to any  of  the  reports  filed  with  the  SEC.  Section  5F of the
Disclosure  Schedule sets forth all substantive  correspondence  between the SEC
and the  Company  concerning  or  relating to  Securities  Act or  Exchange  Act
compliance.

     5G. Absence of Undisclosed  Liabilities.  The Company and the  Subsidiaries
have  no  Liabilities  except  (i)  obligations  under  executory  contracts  or

on the liabilities side of the Latest Balance Sheet and (iii)  Liabilities which
have arisen after the date of the Latest Balance Sheet in the Ordinary Course of

relating to any breach of contract,  breach of warranty,  tort,  infringement or
violation  of  law  or  environmental  matter,  including  those  arising  under
Environmental and Safety Requirements).

     5H. Absence of Certain  Developments.  Except as set forth on Section 5H of

suffered  an  event  which  would  have a  Material  Adverse  Effect,  (ii)  the
businesses  of the Company and the  Subsidiaries  have been operated only in the
Ordinary  Course of Business,  (iii) there has not been any material loss of, or

goods or  services  to the  Company or any  Subsidiary  that is  material to its
business  and (iv) neither the Company nor any  Subsidiary  has taken any of the
following actions:

     stock, (x) declared,  set aside or paid any dividend or other  distribution
     payable in cash,  stock or property with respect to its capital stock,  (y)

     5I. Properties.






         (a)..Attached  as Schedule 5I is a list of all  leases,  subleases  and
other  occupancy  agreements,  including all  amendments,  extensions  and other
modifications  (the  "Leases")  for real  property  (the "Real  Property").  The
Company  has a good  and  valid  leasehold  interest  in and to all of the  Real
Property,  subject  to no Liens.  Each  Lease is in full force and effect and is
enforceable in accordance  with its terms.  There exists no default or condition
which,  with the giving of notice,  the passage of time or both,  would become a
default under any Lease. Except as described on Schedule 5I, no consent, waiver,
approval or  authorization  is required  form any landlord  under any Lease as a
result of the execution of this Agreement, the Stockholders Agreement, the Stock
Purchase Warrant or the consummation of the transactions  contemplated hereby or
thereby.

     (b)......The  Real Property  constitutes  all of the real  property  owned,
lease,  occupied or otherwise  utilized in  connection  with the business of the
Company and its Subsidiaries. Other than the Company and the Subsidiaries, there
are no parties in  possession  or parties  having any current or future right to
occupy any of the Real Property.  All improvements  located on the Real Property
have  direct  access to a public  road  adjoining  such Real  Property.  No such
improvements  or  accessways  encroach on land not included in the Real Property
and no such improvement is dependent for its access, operation or utility on any
land, building or other improvement not included in the Real Property.

     (c)......There  are no  proceedings  in  eminent  domain  or other  similar
proceedings pending or, to the Knowledge of the Company,  threatened,  affecting
any portion of the material Real Property  owned or leased by the Company or any
Subsidiary.  There  exists  no  writ,  injunction,  decree,  order  or  judgment
outstanding,  nor  any  litigation,  pending  or  threatened,  relating  to  the
ownership,  lease,  use,  occupancy  or operation by any Person of any such Real
Property.  The current use of the Real Property does not violate in any material
respect any  instrument  of record or agreement  affecting  such Real  Property.
There  is no  violation  of  any  covenant,  condition,  restriction,  easement,
agreement or order of any governmental authority having jurisdiction over any of
the Real  Property  that  affects  such Real  Property  or the use or  occupancy
thereof,  except a violation which would not have a Material Adverse Effect.  No
damage or  destruction  has occurred  with  respect to any of the Real  Property
that, individually or in the aggregate,  has had or will have a Material Adverse
Effect.

     5J. Assets.  Except as set forth on Section 5J of the Disclosure  Schedule,

thereafter,  free and clear of all Liens,  except for sales of  inventory in the
Ordinary  Course of Business since the date of the Latest Balance Sheet.  Except

good  operating  condition in all material  respects,  reasonable  wear and tear
excepted,  and are fit for use in the Ordinary  Course of Business.  The Company

Purchaser have been duly authorized by Purchaser.  Each of this  Agreement,  the
Stockholders  Agreement and the Stock Purchase  Warrant,  when it is executed by
the other parties  thereto,  will  constitute a valid and binding  obligation of
Purchaser  enforceable  in accordance  with its  respective  terms except to the
extent that the enforceability thereof may be limited by bankruptcy,  insolvency
or similar laws of general application  relating to or affecting the enforcement
of  creditors'  rights or by general  principles  of equity.  The  execution and
delivery by Purchaser of this  Agreement,  the  Stockholders  Agreement  and the
Stock Purchase Warrant, the purchase of the Shares hereunder and the fulfillment
of and compliance  with the respective  terms hereof and thereof by Purchaser do
not and  shall  not (i)  conflict  with or  result  in a  breach  of the  terms,

regulation  to which  Purchaser  is subject,  or (C) any  material  agreement or
instrument,  or any order,  judgment  or decree to which  Purchaser  is subject,
except in the case of (B) and (C) were such conflict, default or violation would
not have a material adverse effect on Purchaser.

     6C. Brokerage. There are no claims for brokerage commissions, finders' fees
or similar compensation in connection with the transactions contemplated by this
Agreement,  based on any  arrangement  or agreement  binding upon  Purchaser for
which the Company or the Subsidiaries could become liable.  Purchaser shall pay,
and  hold  the  Company  harmless  against,  any  Liability,   Loss  or  expense
(including,  without  limitation,  reasonable  attorneys' fees and out-of-pocket
expenses) arising in connection with any such claim.

     6D.  Purchaser's  Investment  Representations.  Purchaser hereby represents
that it is acquiring the Shares purchased  hereunder or acquired pursuant hereto
for its own account with the present  intention of holding such  securities  for
purposes of investment,  and that it has no intention of selling such securities
in a public  distribution  in  violation of the federal  securities  laws or any
applicable state securities laws;  provided that nothing  contained herein shall
prevent  Purchaser  and  subsequent  holders of Shares  from  transferring  such
securities in compliance with the applicable  federal and state securities laws,
subject to the provisions of the Stockholders Agreement.

     Section 7. Termination.

     7A. Termination.  All rights of Purchaser and obligations of the Company to
the Purchaser under Section 4B shall  terminate upon Thayer Shares  constituting
less than 5% of the issued and outstanding Common Stock, and such sections shall
remain  terminated  even if Purchaser,  its Affiliates and any holders of Thayer
Shares  later own in the  aggregate  5% or more of the  issued  and  outstanding
Common Stock; provided that the limited partners of Thayer Equity Investors III,
L.P.  shall not be  treated  as  Affiliates  of Thayer or the  holders of Thayer
Shares  for  the  purposes  of this  Section  7A.  Except  with  respect  to the
representations  and warranties  contained herein, all other rights of Purchaser
and  obligations of the Company to Purchaser  shall  terminate upon the first to
occur of (i)  there  being no Thayer  Shares,  and (ii) the  consummation  of an
Approved Sale.






     Section 8. Representations and Warranties.

     8A. Survival of Representations  and Warranties.  All  representations  and
warranties  contained  herein shall  survive the  execution and delivery of this
Agreement  and the  consummation  of the  transactions  contemplated  hereby and
continue in full force and effect until  thirty days after the Company  delivers
to Purchaser audited financial statements of the Company and the Subsidiaries as
set forth in Section 4A(i)(b) for the fiscal year ending March 31, 1999.

     8B. Indemnification.  Notwithstanding  anything herein to the contrary, the
Company shall not be liable for any inaccuracy of any representation or warranty
contained herein unless all such  inaccuracies,  in the aggregate,  shall have a
Material  Adverse  Effect,  provided  that for the  purpose of  determining  any
inaccuracy of a representation or warranty,  any qualification as to materiality
or Material Adverse Effect contained therein shall be ignored.

     Section 9. Miscellaneous.

     9A.  Expenses.  The Company shall pay all  out-of-pocket  fees and expenses
(including  reasonable attorneys fees) of the Company and the Purchaser incurred
in  connection  with  this  Agreement,  the  Stockholders  Agreement,  the Stock
Purchase Warrant and the transactions contemplated hereby and thereby.

     9B. Consent to Amendments.  Except as otherwise  expressly provided herein,
the  provisions  of this  Agreement may be amended or waived and the Company may
take any action herein prohibited, or omit to perform any act herein required to
be performed by it, only if the Company has obtained the prior  written  consent
of  Purchaser.  No other course of dealing  between the Company and Purchaser or
any delay in exercising any rights hereunder or under the Stockholders Agreement
or the Stock  Purchase  Warrant  shall  operate as a waiver of any rights of any
such holders.

     9C. Successors and Assigns.  Except as otherwise expressly provided herein,
this Agreement  shall bind and inure to the benefit of and be enforceable by the
Company and Purchaser and their  respective  permitted  successors  and assigns,
provided,  however that Purchaser  shall not assign this Agreement or any of the
rights or interests  hereunder (except any right or interest directly related to
the  ownership of the Shares) to any Person other than an Affiliate of Purchaser
within two years of the date hereof.

     9D. Severability. Whenever possible, each provision of this Agreement shall
be interpreted in such manner as to be effective and valid under applicable law,
but if any  provision of this  Agreement is held to be  prohibited by or invalid
under  applicable law, such provision shall be ineffective only to the extent of
such  prohibition  or  invalidity,  without  invalidating  the remainder of this
Agreement.






     9E. Counterparts.  This Agreement may be executed  simultaneously in two or
more counterparts, any one of which need not contain the signatures of more than
one party, but all such counterparts taken together shall constitute one and the
same Agreement.

     9F. Descriptive Headings;  Interpretation. The descriptive headings of this
Agreement are inserted for convenience  only and do not constitute a substantive
part of this Agreement.  The use of the word "including" in this Agreement shall
be by way of example rather than by limitation.

     9G.  Governing Law. All issues and questions  concerning the  construction,
validity,  enforcement and interpretation of this Agreement and the exhibits and
schedules hereto  (including the Disclosure  Schedule) shall be governed by, and
construed in accordance with, the laws of the State of Delaware,  without giving
effect to any choice of law or conflict of law rules or  provisions  (whether of
the  State  of  Delaware  or  any  other  jurisdiction)  that  would  cause  the
application of the laws of any jurisdiction other than the State of Delaware.
