     Section 3.  Representations, Warranties and Covenants of the Securing
     ----------  ---------------------------------------------------------
Parties.
- ------- 

     A.  Perfection.  At any time and from time to time, upon demand of the
Agent, each Securing Party will:

          (1) Deliver and pledge (or cause to be delivered and pledged) to the
     Agent, endorsed and/or accompanied by such further instruments of
     assignment and transfer in such form and substance as the Agent may
     reasonably request, any and all cash equivalents (other than balances in
     bank accounts), instruments, securities, investments, documents and/or
     chattel paper included in or evidencing or otherwise relating to the
     Collateral owned or held by such Securing Party as the Agent may specify;

          (2) Execute and deliver to the Agent a mortgage or mortgages
     (satisfactory in form and substance to the Agent) creating Liens in favor
     of the Agent securing the Secured Obligations on any real property
     (including, without limitation, leasehold interests) of the Securing
     Parties, or such portion thereof as may be specified by the Agent, and take
     such action as may be necessary to duly file and/or record such Liens in
     such public office or offices, and take such other actions (including using
     reasonable efforts for a reasonable period of time to obtain consents and
     acknowledgments of landlords and other third parties) as may be

 
                                       5

     necessary or desirable (in the opinion of the Agent), in order for such
     Liens to constitute valid and effective Liens on such real property as
     security for the Secured Obligations, subject to no equal or prior Liens
     (other than Permitted Liens and the other Liens permitted by, and subject
     to, Section 8.12 of the Credit Agreement);

          (3) To the extent any of the Collateral owned or held by such Securing
     Party consists of property which constitutes fixtures under the laws of the
     jurisdiction in which such property is located, use reasonable efforts for
     a reasonable period of time to furnish or cause to be furnished to the
     Agent valid and effective waivers of interest in such Collateral by all
     landlords, lessors, mortgagees, co-owners, encumbrances or other parties in
     interest with respect to the real property upon which such Collateral is
     located;

          (4) If and to the extent determined by the Agent, at the direction of
     the Majority Lenders, to be desirable to protect the interests of the Agent
     and the Lenders (and in any event with respect to Contracts only after a
     Default or Event of Default and an acceleration by the Agent pursuant to
     Article IX of the Credit Agreement), notify each obligor upon any credit or
     other obligation included in the Collateral at any time owing to such
     Securing Party, in such manner as the Agent may specify; and

          (5) Permit representatives of the Agent or any Lender, during business
      hours, to inspect the inventory and other properties constituting
      Collateral of such Securing Party and to inspect and make abstracts from
      its books and records pertaining to the Collateral, allow the Agent or any
      Lender to speak with representatives or employees of such Securing Party,
      and assist the Agent or such Lender's representative obtaining any
      information requested by the Agent or such Lender.

     B.  Necessary Filings.  With the exception of landlord consents and waivers
         -----------------                                                      
and fixture filings. all filings, registrations and recordings necessary,
appropriate or reasonably requested by the Agent to create, preserve, protect
and perfect the security interest granted by the Securing Parties to the Agent
hereby in respect of the Collateral and required to be made on or before the
date hereof have been accomplished.  The security interest granted to the Agent
for the benefit of the Lenders pursuant to this Security Agreement in and to the
Collateral constitutes and hereafter

 
                                       6

will constitute a perfected security interest therein, superior and prior to the
rights of all persons therein and subject to no other Liens except Liens which
are permitted by, and subject to, Section 8.12 of the Credit Agreement.

     C.  Insurance.  Each of the Securing Parties will maintain insurance issued
         ---------                                                              
by responsible companies, satisfactory to the Agent, in such amounts and against
such risks as is response usually carried by owners of similar businesses and
properties in the same general areas in which such Securing Party operates;
provided, however, that, if any Event of Default or Default shall be continuing,
- --------  -------                                                               
the Securing Parties will insure the Collateral or will cause the Collateral
which is tangible property to be insured against such risks as the Agent, at the
direction of the Majority Lenders, may from time to time reasonably require,
such insurance to be in such forms and amounts and with such companies as may be
satisfactory to the Agent and the Majority Lenders. To the extent available from
applicable insurers, all policies of such insurance shall, unless otherwise
specified by the Agent, be written for the benefit of the Securing Parties and
the Agent (for its own benefit and that of the Lenders) as their interests may
appear and shall provide that such insurance may not be canceled by reason of
the act or neglect of any Securing Party and shall provide that the rights of
the Agent and Lenders are independent of any breach of condition by the named
insured, and all such policies or certificates evidencing the same, shall be
furnished to the Agent.  Each Securing Party hereby assigns to the Agent as part
of the Collateral all returned or unearned premiums which may be due upon the
cancellation of any of such policies for any reason whatsoever and hereby
directs the insurer thereunder to pay to the Agent any amounts so due.  Each
Securing Party will cause the carriers of its insurance to issue loss payee and
additional insured or mortgagee clauses in favor of the Agent with respect to
such insurance and to cause such carriers to give not less than ten days' prior
notice to the Agent of the cancellation or non-renewal of any of such policies.

     D.  Liens.  The Securing Parties will not, without the prior written
consent of the Majority Lenders:

          (1) Permit any of the Collateral to be levied upon under legal process
     or be subject to any Lien of whatsoever nature (except for those created
     hereby, Permitted Liens and other Liens to the

 
                                       7

     extent permitted by, and subject to, Section 8.12 of the Credit Agreement)
     unless promptly discharged; or

          (2) Cause or permit anything to be done which may materially impair
     the value of the Collateral (other than normal wear and tear with respect
     to property and fixtures included in the Collateral and dispositions
     permitted by Section 8.14 of the Credit Agreement) or the Liens granted
     and/or intended to be granted hereby.

     E.  Notations.  Each of the Securing Parties will keep and stamp or
         ---------                                                      
otherwise mark any and all documents and chattel paper and its individual books
and records relating to the Collateral in such manner as the Agent may
reasonably require.

     F.  Place of Business/Location of Collateral.  Each of the Securing Parties
         ----------------------------------------                               
represents and warrants to the Lenders that the chief executive office and
principal place of business of such Securing Party, and the place where such
Securing Party keeps all of its books and records, is specified in Schedule I
hereof.  All tangible evidence and all receivables, contracts and general
intangibles of each Securing Party and the only original books of account and
records of such Securing Party relating thereto are, and will continue to be,
kept at such chief executive office and principal place of business, or at such
new location for such chief executive office and principal place of business as
such Securing Party may establish in accordance with the last sentence of this
Section F. All Collateral of each Securing Party is located at one of the
locations for such Securing Party listed on Schedule I hereof, and will remain
located at any one of such locations unless the Securing Party shall have given
the Agent at least 45 days prior written notice of its intention to remove
Collateral from such location clearly describing the proposed new location which
shall be in the United States of America.  No Securing Party shall establish a
new location for its chief executive office and principal place of business nor
shall it change its corporate name or the name under which it is conducting
business, until (i) it shall have given to the Agent not less than 45 days prior
written notice of its intention to do so, clearly describing such new location
(which shall be in the United States of America) or name, and providing such
other information in connection therewith as the Agent may reasonably request,
and (ii) with respect to such new location or name, the Securing Parties shall
have taken all actions satisfactory to the Agent to maintain the perfection and
proof of the

 
                                       8

security interest of the Agent for the benefit of the Lenders in the Collateral
intended to be granted hereby, including, without limitation, obtaining waivers
of landlord's or warehouseman's liens with respect to such new location.

     Section 4.  Further Assurances, Etc.  Each of the Securing Parties will,
     ---------   ------------------------                                    
from time to time and at their own expense, promptly execute, acknowledge,
witness and deliver and file and/or record, or cause the execution,
acknowledgment, witnessing, and delivery and the filing and/or recordation of,
such specific and further assignments of Collateral and such other documents or
instruments, and shall take or cause to be taken such other action as the Agent
may reasonably request for the perfection against such Securing Party and all
third parties whomsoever of the Liens created hereby, or for the continuation
and protection thereof, and promptly furnish to the Agent evidence satisfactory
to the Agent of such action.  Without limiting the generality of the foregoing,
each of the Securing Parties promptly upon the execution and delivery of this
Agreement, and at any time and from time to time thereafter upon the request of
the Agent, will execute, acknowledge, witness and deliver such financing and
continuation statements, notices, and additional security agreements, make such
notations on its records, and take such other action as the Agent may reasonably
request for the purpose of so perfecting, maintaining and protecting such Liens
and shall cause this Agreement, any amendment or supplement hereto or thereto
and each such financing and continuation statement, notice and additional
security agreements to be filed and/or recorded in such manner and in such
places as may be required by applicable law or as the Agent may reasonably
request for such purpose.  After written notice to the Securing Parties, each of
the Securing Parties hereby authorizes the Agent to effect any filing and/or
recording which the Agent or the Majority Lenders has requested pursuant to this
Section 4 without the signature of such Securing Party, to the extent permitted
by applicable law.  The Agent shall give the Securing Parties written notice
subsequent to any such filing and/or recording.

     Section 5.  Actions by Agent.  The Agent may, at any time and from time to
     ---------   ----------------                                              
time, at its option, after having given notice of its intention to do so to the
Securing Parties, perform any act which is undertaken by any of the Securing
Parties to be performed by such Securing Party hereunder but which such Securing
Party shall have failed to perform, and the Agent may take any other action
which the Agent may deem necessary for the

 
                                       9

maintenance, preservation or protection of any of the Collateral or the security
interests therein, and the Agent is hereby irrevocably appointed attorney-in-
fact of each of the Securing Parties for this purpose.  All moneys advanced by
the Agent in connection with any of the foregoing, together with interest
thereon at the highest rate then in effect pursuant to the Credit Agreement from
the date of such advance to the date of the repayment thereof, shall be repaid
by the Securing Parties to the Agent upon demand, and shall constitute
additional Secured Obligations secured hereby.  The making of any such advance
by the Agent shall not, however, relieve any of the Securing Parties of
liability for any default hereunder until the full amount of all such moneys so
advanced and such interest thereon shall have been repaid by the Securing
Parties to the Agent and such default shall have otherwise been cured.

     Section 6.  Rights and Remedies Upon Default.
     ---------   -------------------------------- 

     A.  Rights and Remedies Generally.  Upon the occurrence and during the
         -----------------------------

remedies of a secured party under the Massachusetts Uniform Commercial Code, or
other applicable law, including the power of sale upon notice, and all rights
provided herein, all of which rights and remedies shall, to the fullest extent
permitted by law, be cumulative, provided that the Agent shall not notify
                                 --------

continuing, each of the Securing Parties will at the request of the Agent cause
all payments made under or in respect of accounts or other obligations owed to
such Securing Party to be paid directly to the Agent.  The Agent shall hold all
such payments as additional Collateral hereunder.  Neither the Agent nor any
Lender shall be liable to any Person for any incorrect or improper payment made
pursuant to this Section 6.B(1) in the absence of gross negligence or willful
misconduct.

     (2) Each of the Securing Parties hereby constitutes the Agent its true and
lawful attorney, irrevocably and with full power of substitution, in the name of

other obligations, (iii) to endorse any checks or other instruments or orders in
connection therewith, (iv) to file any claims or take any actions or institute
any proceedings which the Agent may deem to be necessary or advisable in its
sole and complete discretion and to compromise, litigate or settle the same and
(v) to take any other action which by the terms of this Agreement is to be taken
by such Securing Party.

     (3) (a) Upon the occurrence and during the continuance of any Event of
Default, the Agent may do any one or more of the following acts:

     the Liens created hereby;

          (iv) institute legal proceedings for the sale, under a judgment or
     decree of any court of competent jurisdiction, of any of the Collateral;

          (v) institute legal proceedings for the appointment of a receiver or

          (vi) personally, or by agents or attorneys, enter into and upon any
     premises wherein the Collateral or any part thereof may then be situated
     and take possession of all or any part thereof or render it unusable; and,
     without being responsible (except for gross negligence or willful
     misconduct) for loss or damage, hold, store,

 
                                       11

     and keep idle, or operate, lease, or otherwise use or permit the use of the
     same or any part thereof, for such time and upon such terms as the Agent
     may deem to be in the best interests of the Lenders, and demand, collect,
     and retain all hire, earnings and all other sums due and to become due in
     respect of the same from any party whomsoever, accounting only for net
     earnings, if any, arising from such use, after charging against all
     receipts from the use of the same and from any subsequent sale thereof, by
     court proceedings or pursuant to clause (vii) of this Section 6.B(3)(a),
     all reasonable costs and expenses of, and damages or losses by reason of,
     such use and/or sale; and/or

          (vii) personally, or by agents or attorneys, enter upon and into any
     place wherein the same may then be located and take possession of any part
     or all of the Collateral, with or without process of law and without being
     responsible for loss or damage (except such as results from the Agent's
     gross negligence or willful misconduct), and sell, lease or otherwise
     dispose of all or any part of the same, free from any and all claims of any
     of the Securing Parties at law, in equity, or otherwise, at one or more
     public or private sales, in such place or places, at such time or times,
     for cash or credit and upon such terms as the Agent or the Majority Lenders
     may determine, with or without any previous demand or notice to any of the
     Securing Parties or advertisement and demand, and any right or equity of
     redemption otherwise required by law is hereby waived by each of the
     Securing Parties to the fullest extent permitted by applicable law. The

designated by the Agent.

     (c) In the event that any mandatory requirement of applicable law shall
obligate the Agent to give prior notice to any of the Securing Parties of any of
the foregoing acts, each of the Securing Parties agrees that a notice sent to
the Company in writing by certified U.S. mail, return receipt requested, at
least five days before the date of any such act, at the

 
                                       12

Company's address specified in Schedule 11.02 of the Credit Agreement (or such
other address as shall have been notified to the Agent in writing), shall be
deemed to be reasonable notice of such act and, specifically, reasonable
notification of the time and place of any public sale hereunder and reasonable
notification of the time after which any private sale or other intended
disposition to be made hereunder is to be made.

     (d) The Agent shall apply the proceeds from the sale or other disposition
of the Collateral in accordance with the terms and provisions of the Credit
Agreement.

     (e) No sale or other disposition of all or any part of the Collateral by
