                    CONTINUING UNCONDITIONAL SECURED GUARANTY
                                       BY
                                   HOUBA INC.

         WHEREAS, HALSEY DRUG CO., INC., a New York corporation (the
"Borrower"), entered into a Debenture Purchase Agreement dated as of December
20, 2002 (as amended through the date hereof, the "Purchase Agreement"; terms
used herein and not otherwise defined shall have the meanings given to them in
the Purchase Agreement) with the Purchasers listed on Exhibit A thereto (each a
"Lender" and collectively, the "Lenders");

         WHEREAS, pursuant to the Purchase Agreement, the Lenders have made
financial accommodations to the Borrower in accordance with the terms of the
Purchase Agreement;

         WHEREAS, Houba Inc. (the "Guarantor") will continue to receive certain
benefits from the accommodations hereinabove described and is therefore willing
to guaranty the prompt payment and performance of the obligations of the
Borrower, on the terms set forth in this Continuing Unconditional Secured
Guaranty ("Guaranty");

         WHEREAS, pursuant to the Purchase Agreement, the Lenders have required
that the Guarantor execute and deliver this Guaranty to Galen Partners III,
L.P., a Delaware limited partnership, acting in its capacity as agent for the
Lenders (the "Agent"), for the benefit of the Lenders, as a condition to the
effectiveness of the Purchase Agreement; and

         WHEREAS, the extension of credit by the Lenders to the Borrower is
necessary and desirable to the conduct and operation of the business of the
Borrower and will inure to the financial benefit of the Guarantor.

         NOW, THEREFORE, for value received and in consideration of any loan,
advance, or financial accommodation of any kind whatsoever heretofore, now or
hereafter made, given or granted to the Borrower by the Lenders (including,
without limitation, the loans evidenced by the Debenture as made by the Lenders
to the Borrower pursuant to, the Purchase Agreement) and other good and valuable
consideration (the sufficiency and receipt of which are hereby acknowledged),
the Guarantor unconditionally guarantees to the Agent for the benefit of the
Lenders (i) the full and prompt payment and performance when due, whether at
maturity or earlier, by reason of acceleration or otherwise, and at all times
thereafter, of all liabilities of the Borrower to the Lenders and (ii) the
prompt, full and faithful discharge by the Borrower of each and every term,
condition, agreement, representation, warranty or covenant now or hereafter made
by the Borrower to the Lenders, in each case, and the Agent under these clauses
(i) and (ii), pursuant to the Purchase Agreement, the Debentures, the other
Transaction Documents (as defined in the Subordination Agreement) or any
document or instrument delivered by the Borrower to the Lenders in connection
therewith or pursuant thereto (which, together with the liabilities described in
clause (i) hereof, are collectively referred to herein as the "Borrower's
Liabilities"). The Guarantor further agrees to pay all reasonable out-of-pocket
costs and expenses, including, without limitation, all court costs and
reasonable attorneys' and paralegals' fees paid or incurred by the Lenders and
the Agent (on behalf of the Lenders),
<PAGE>
in endeavoring to collect all or any part of the Borrower's Liabilities from, or
in prosecuting any action against the Guarantor or any other guarantor of all or
any part of the Borrower's Liabilities.

         Notwithstanding any provision of this Guaranty to the contrary, it is
intended that this Guaranty, and any liens and security interests granted by the
Guarantor to secure this Guaranty, not constitute a Fraudulent Conveyance (as
defined below). Consequently, the Guarantor agrees that if this Guaranty, or any
liens or security interests securing this Guaranty, would, but for the
application of this sentence, constitute a Fraudulent Conveyance, this Guaranty
and each such lien and security interest shall be valid and enforceable only to
the maximum extent that would not cause this Guaranty or such lien or security
interest to constitute a Fraudulent Conveyance, and this Guaranty shall
automatically be deemed to have been amended accordingly at all relevant times.
For purposes hereof, "Fraudulent Conveyance" means a transfer of property or the
incurrence of liability which would be avoidable under Section 548 or 544(b) of
the "Bankruptcy Code" (as hereinafter defined) or under the provisions of any
applicable fraudulent conveyance or fraudulent transfer law or similar law of
any state, nation or other governmental unit, as in effect from time to time.

         The Guarantor hereby agrees that, except as hereinafter provided, and
to the extent permitted by applicable law, its obligations under this Guaranty
shall be unconditional, irrespective of (i) the validity or enforceability of
the Borrower's Liabilities or any part thereof, or of any Debenture or other
document evidencing all or any part of the Borrower's Liabilities, (ii) the
absence of any attempt to collect the Borrower's Liabilities from the Borrower
or any other guarantor or other action to enforce the same, (iii) the waiver or
consent by the Agent, any Lender or Lenders with respect to any provision of any
instrument evidencing the Borrower's Liabilities, or any part thereof, or any
other agreement heretofore, now or hereafter executed by the Borrower and
delivered to the Agent, the Lender or Lenders, (iv) failure by the Agent or any
Lender to take any steps to perfect and maintain its security interest in, or to
preserve its rights to, any security or collateral for the Borrower's
Liabilities, (v) the institution of any proceeding under Chapter 11 of Title 11
of the United States Code (11 U.S.C. Section 101 et seq.), as amended (the
"Bankruptcy Code"), or any similar proceeding, by or against the Borrower, or
the Agent's or any Lender's election in any such proceeding of the application
of Section 1111(b)(2) of the Bankruptcy Code, (vi) any borrowing or grant of a
security interest by the Borrower as debtor-in-possession, under Section 364 of
the Bankruptcy Code, (vii) the disallowance, under Section 502 of the Bankruptcy
Code, of all or any portion of the Lenders' claim(s) for repayment of the
Borrower's Liabilities, or (viii) any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

         The Guarantor hereby waives diligence, presentment, demand of payment,
filing of claims with a court in the event of receivership or bankruptcy of the
Borrower, protest or notice with respect to the Borrower's Liabilities and all
demands whatsoever, and covenants that this Guaranty will not be discharged,
except by complete performance of the obligations and liabilities contained
herein. Upon the occurrence and during the continuance of an Event of Default
under the Purchase Agreement, Lenders holding a majority in outstanding
principal amount of the Debentures may, at their sole election, proceed directly
and at once, without notice, against the Guarantor to collect and recover the
full amount or any portion of the Borrower's Liabilities, without first
proceeding against

                                       2
<PAGE>
any other person, firm, or corporation, or against any security or collateral
for the Borrower's Liabilities.

         The Guarantor hereby unconditionally and irrevocably agrees not to
exercise any rights that it may now have or hereafter acquire against the
Borrower or any other insider guarantor that arise from the existence, payment,
performance or enforcement of the Borrower's Liabilities under or in respect of
this Guaranty, the Purchase Agreement, the Debentures, the other Transaction
Documents or any document or instrument delivered by the Borrower to the Lenders
in connection therewith or pursuant thereto, including, without limitation, any
right of subrogation, reimbursement, exoneration, contribution or
indemnification and any right to participate in any claim or remedy of the Agent
or the Lenders against the Borrower or any other insider guarantor or any
Collateral, whether or not such claim, remedy or right arises in equity or under
contract, statute or common law, including, without limitation, the right to
take or receive from the Borrower or any other insider guarantor, directly or
indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim, remedy or right, unless and until
the Security Interest Termination Date. If any amount shall be paid to any
Guarantor in violation of the immediately preceding sentence at any time prior
to the indefeasible payment in full in cash of the Borrower's Liabilities and
all other amounts payable under this Guaranty, such amount shall be received and
held in trust for the benefit of the Lenders, shall be segregated from other
property and funds of the Guarantor and shall forthwith be paid or delivered to
the Agent in the same form as so received (with any necessary endorsement or
assignment) to be credited and applied to the Borrower's Liabilities and all
other amounts payable under this Guaranty, whether matured or unmatured, in
accordance with the terms of the Debentures and the Purchase Agreement, or to be
held as collateral for any Borrower's Liabilities or other amounts payable under
this Guaranty thereafter arising. Upon the Security Interest Termination Date,
except in the case of a Reinstatement Event (as defined below), the Agent and
the Lenders will, at the Guarantor's request and expense, execute and deliver to
the Guarantor appropriate documents, without recourse and without representation
or warranty, necessary to evidence the transfer by subrogation to the Guarantor
of an interest in the Borrower's Liabilities resulting from such payment made by
the Guarantor pursuant to this Guaranty.

         The Lenders are hereby authorized, without notice or demand and without
affecting the liability of the Guarantor hereunder, at any time and from time to
time to (i) renew, extend, accelerate or otherwise change the time for payment
of, or other terms relating to the Borrower's Liabilities or otherwise modify,
amend or change the terms of any debenture, note or other agreement, document or
instrument now or hereafter executed by the Borrower and delivered to the
Lenders; (ii) accept partial payments on the Borrower's Liabilities; (iii) take
and hold security or collateral for the payment of the Borrower's Liabilities
guaranteed hereby, or for the payment of this Guaranty, or for the payment of
any other guaranties of the Borrower's Liabilities or other liabilities of the
Borrower, and exchange, enforce, waive and release any such security or
collateral; (iv) apply such security or collateral and direct the order or
manner of sale thereof as in their sole discretion they may determine; and (v)
settle, release, compromise, collect or otherwise liquidate the Borrower's
Liabilities and any security or collateral therefor in any manner, without
affecting or impairing the obligations of the Guarantor hereunder. The holders
of the majority of the outstanding principal amount of the Debentures shall have
the exclusive right to determine the time and manner of application of any
payments or credits, whether received from the Borrower or any other source, and
such determination shall be binding on the Guarantor. All such payments and
credits may be

                                       3
<PAGE>
applied, reversed and reapplied, in whole or in part, to any of the Borrower's
Liabilities as the Lenders shall determine in their sole discretion without
affecting the validity or enforceability of this Guaranty (unless otherwise
required pursuant to the Purchase Agreement).

         The Guarantor hereby assumes responsibility for keeping itself informed
of the financial condition of the Borrower, and any and all endorsers and/or
other guarantors of any instrument or document evidencing all or any part of the
Borrower's Liabilities and of all other circumstances bearing upon the risk of
nonpayment of the Borrower's Liabilities or any part thereof that diligent
inquiry would reveal and the Guarantor hereby agrees that neither the Agent nor
the Lenders shall have any duty to advise the Guarantor of information known to
any of them regarding such condition or any such circumstances or to undertake
any investigation not a part of their respective regular business routines. If
the Agent or any Lender, in their respective sole discretions, undertake at any
time or from time to time to provide any such information to the Guarantor, the
Agent or such Lender, as the case may be, shall not be under any obligation to
update any such information or to provide any such information to the Guarantor
on any subsequent occasion.

         The Guarantor consents and agrees that neither the Agent nor the
Lenders shall be under any obligation to marshall any assets in favor of the
Guarantor or against or in payment of any or all of the Borrower's Liabilities.
The Guarantor further agrees that, to the extent that the Borrower makes a
payment or payments to the Lenders or the Lenders receive any proceeds of
collateral, which payment or payments or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to the Borrower, its estate, trustee, receiver or any
other party, including, without limitation, the Guarantor, under any bankruptcy
law or state or federal statutory or common law, then to the extent of such
payment or repayment, the Borrower's Liabilities or the part thereof which has
been paid, reduced or satisfied by such amount, and the Guarantor's obligations
hereunder with respect to such portion of the Borrower's Liabilities, shall be
reinstated and continued in full force and effect as of the date such initial
payment, reduction or satisfaction occurred. Notwithstanding anything else to
the contrary contained herein, the Guarantor consents and agrees that this
Guaranty shall continue to be effective or be reinstated, as the case may be, if
at any time any payment of any of the Borrower's Liabilities is rescinded or
must otherwise be returned by any Lender or any other Person upon the
insolvency, bankruptcy or reorganization of the Borrower or the Guarantor or
otherwise, all as though such payment had not been made (each such continuation
or reinstatement, a "Reinstatement Event").

         Until the Security Interest Termination Date, the Guarantor hereby
waives any and all claims (including, without limitation, any claim for
reimbursement, contribution or subrogation) of the Guarantor against the
Borrower, any endorser or any other guarantor of all or any part of the
Borrower's Liabilities, or against any of the Borrower's properties, arising by
reason of any payment by the Guarantor to the Lenders pursuant to the provisions
hereof.

         Each Lender may, to the extent and in the manner set forth in the
Purchase Agreement, sell or assign the Borrower's Liabilities or any part
thereof, or grant participations therein, and in any such event each and every
permitted assignee or holder of, or participant in, all or any of the Borrower's
Liabilities shall have the right to enforce this Guaranty, by suit or otherwise

                                       4
<PAGE>
for the benefit of such assignee, holder, or participant, as fully as if herein
by name specifically given such right.

         The Guarantor hereby represents and warrants that: (a) it is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Indiana; (b) it is duly authorized and empowered to execute and
deliver this Guaranty; (c) all corporate action on the part of the Guarantor
requisite for the due execution and delivery of this Guaranty and the due
granting and creation of the security interests referred to herein has been duly
and effectively taken; (d) the Guarantor's chief executive office is located at
695 North Perryville Road, Rockford, Illinois 61107 and (e) execution, delivery
and performance of this Guaranty will not result in any violation of, conflict
with, or result in a breach of, any of the terms of, or constitute a default
under, any agreements, contracts, court orders or consent decrees, the
Certificate of Incorporation or the By-laws, as amended, of the Guarantor.

         This Guaranty shall be binding upon the Guarantor and upon the
successors (including without limitation, any receiver, trustee or debtor in
possession of or for the Guarantor) of the Guarantor and shall inure to the
benefit of the Lenders and their respective successors and permitted assigns.
Notwithstanding anything contained herein to the contrary, this Guaranty may not
be assigned by the Guarantor without the prior written consent of the Lenders.

         This Guaranty shall continue in full force and effect, and the Lenders
shall be entitled to make loans and advances and extend financial accommodations
to the Borrower on the faith hereof, until the Security Interest Termination
Date and the Purchase Agreement has been terminated and the Debentures canceled.
The Guarantor hereby unconditionally and irrevocably waives any right to revoke
this Guaranty and acknowledges that this Guaranty is continuing in nature and
applies to all Borrower's Liabilities, whether existing now or in the future.

         Notwithstanding anything to the contrary contained herein, the rights
and remedies of the Agent and the Lenders, and the obligations of the
Guarantors, under this Guaranty are subject to the Subordination Agreement, as
it may be amended, supplemented or otherwise modified from time to time.

         Wherever possible each provision of this Guaranty shall be interpreted
in such manner as to be effective and valid under applicable law, but if any
provision of this Guaranty shall be prohibited by or invalid under such law,
such provision shall be ineffective to the extent of such prohibition or
invalidity without invalidating the remainder of such provision or the remaining
provisions of this Guaranty.

         THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK WHEREIN THE TERMS OF THIS GUARANTY WERE
NEGOTIATED, EXCLUDING TO THE GREATEST EXTENT PERMITTED BY LAW ANY RULE OF LAW
THAT WOULD CAUSE THE APPLICATION OF ANY JURISDICTION OTHER THAN THE STATE OF NEW
YORK.

         The Guarantor hereby irrevocably and unconditionally submits, for
itself and its

                                       5
<PAGE>
property, to the nonexclusive jurisdiction of any New York State court or United
States Federal court sitting in New York City, and any appellate court from any
thereof, in any action or proceeding arising our of or relating to this Guaranty
or any of the other Transaction Documents (as such term is defined in the
Purchase Agreement) (the "Transaction Documents") to which it is a party, or for
recognition or enforcement of any judgment, and each of the parties hereto
irrevocably and unconditionally agrees that all claims in respect of any such
action or proceeding may be heard and determined in any such New York State
court or, to the fullest extent permitted by law, in such United States Federal
court. The Guarantor agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the right that any party may otherwise have to bring any action or
proceeding relating to this Guaranty or any of the other Transaction Documents
in the courts of any other jurisdiction.

         The Guarantor irrevocably and unconditionally waives, to the fullest
extent it may legally and effectively do so, any objection that it may now or
hereafter have to the laying of venue of any suit, action or proceeding arising
out of or in relation to this Guaranty or any other Transaction Document to
which it is a party in any such New York State or United States Federal court
sitting in New York City. The Guarantor hereby irrevocably waives, to the
fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court.

         EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL
BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT,
TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY TRANSACTION DOCUMENT OR THE
ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR
ENFORCEMENT THEREOF.

         SECTION III. THE GUARANTORS' REPRESENTATIONS AND
                      WARRANTIES.

         Each Guarantor severally represents and warrants as follows:

         A.       Places of Business. Such Guarantor has no places of business,
or warehouses in which it leases space, other than those set forth on Section
IIIA of Schedule A, a copy of which is attached hereto and made a part hereof
("Schedule A").

         B.       Location of Collateral. Except for the movement of Collateral
from time to time from one place of business or warehouse listed on Section IIIA
of Schedule A to another place of business or warehouse listed on Section IIIA
of such Schedule A, the Collateral is located at such Guarantor's chief
executive offices or other places of business or warehouses listed on such
Section IIIA of Schedule A, and not at any other location.

         C.       Restrictions on Collateral Disposition. None of the Collateral
is subject to contractual obligations that may restrict or inhibit the Agent's
rights or ability to sell or dispose of the Collateral or any part thereof after
the occurrence of an Event of Default except (i) the rights of Watson under the
Watson Loan Agreement and the documents executed in connection therewith,
including, without limitation, the Watson Security Agreement dated as of March
29, 2000 (the "Watson Security Agreement"); (ii) the rights of the investors in
the 5% convertible senior secured debentures due March 31, 2006 issued pursuant
to a certain Debenture and Warrant Purchase Agreement dated March 10, 1998, as
amended, between the Company and the purchasers listed on the signature page
thereto (the "March 1998 Debentures"); and (iii) the rights of the investors in
the 5% convertible senior secured debentures due March 31, 2006 issued pursuant
to certain Debenture and Warrant Purchase Agreement dated May 26, 1999, as
amended, between the Company and the purchasers listed on the signature page
thereto (the "May 1999 Debentures").

         D.       Status of Accounts. Status of Accounts. Each Account is based
on an actual and bona fide rendition of services or sale of goods/products to
customers, made by such Guarantor in the ordinary course of its business; the
Accounts created are its exclusive property and are not and shall not be subject
to any lien, consignment arrangement, encumbrance, security interest or
financing statement whatsoever, except (i) the lien in favor of Watson under the
Watson Loan Agreement and the documents executed in connection therewith,
including, without limitation, the Watson Security Agreement, (ii) the lien in
favor of the investors in the March 1998 Debentures and (iii) the lien in favor
of the investors in the May 1999 Debentures, and to the best knowledge of such
Guarantor, such Guarantor's customers have accepted the goods/products and
services, and owe and are obligated to pay the full amounts stated in the
invoices according to their terms, without any dispute, offset, defense or
counterclaim.

         E.       Copyrights, Trademarks and Patents.

                  (i)      Each of the Guarantors owns outright all of the
Intellectual Property Rights listed on Section 4.12 of the Schedule of
Exceptions attached to the Purchase Agreement free

                                      -5-
<PAGE>
and clear of all liens and encumbrances except for the Permitted Encumbrances
and pays no royalty to anyone under or with respect to any of them.

                  (ii)     Each of the Guarantors has not licensed to anyone
the use of any of such Intellectual Property Rights and has no knowledge of the
infringing use by the Company or any Guarantor of any intellectual property
rights of third parties.

                  (iii)    Each of the Guarantors has no knowledge, nor has it
received any notice (a) of any conflict with the asserted rights of others with
respect to any Intellectual Property Rights used in, or useful to, the operation
of the business conducted by the Company and the Guarantors or with respect to
any license under which the Company or a Guarantor is licensor or licensee; or
(b) that the Intellectual Property Rights infringe upon the rights of any third
party.

                  (iv)     Each of the Guarantors has made or performed all
filings, recordings and other acts and has paid all required fees and taxes to
maintain and protect its interest in each and every item of intellectual
property in full force and effect throughout the world, and to protect and
maintain its interest therein including, without limitation, recordations of any
of its interests in patents and trademarks with the U.S. Patent and Trademark
Office and in corresponding national and international patent offices, and
recordation of any of its interests in any copyrights with the U.S. Copyright
Office and in corresponding national and international copyright offices. Each
of the Guarantors has used proper statutory notice in connection with its use of
each patent, trademark and copyright.

         F.       Inventory. All inventory of the Guarantors consists of a
quality and quantity usable and salable in the ordinary course of business,
except for obsolete items and items of below-standard quality, all of which have
been or will be written off or written down to net realizable value on the
consolidated balance sheet of the Guarantors and its Subsidiaries as of June 30,
2002. The quantities of each type of inventory (whether raw materials,
work-in-process, or finished goods) are not excessive, but are reasonable and
warranted in the present circumstances of the Guarantors.

         G.       Ownership. Each of the Guarantors is the legal and beneficial
owner of the Collateral of the Guarantors free and clear of any lien, claim,
option or right of others, except for the security interest created under this
Guarantors General Security Agreement, the Watson Security Agreement and the
Company Security Agreements executed in connection with the March 1998
Debentures and the May 1999 Debentures. No effective financing statement or
other instrument similar in effect covering all or any part of such Collateral
or listing the Guarantors or any trade name of the Guarantors is on file in any
recording office, except such as may have been filed relating to the Watson Loan
Agreement, the March 1998 Debentures and the May 1999 Debentures. The Agent has,
for the benefit of the Purchasers, a valid and perfected security interest in
the Collateral which security interest has priority over any and all other
security interests (except as provided in the Subordination Agreement) in such
Collateral.

         SECTION IV. COVENANTS OF THE GUARANTORS.

                                       -6-
<PAGE>
         Each Guarantor agrees (which agreements shall be several as to each
Guarantor except as otherwise provided) as follows:

         A.       Defend Against Claims. Such Guarantor will defend the
Collateral against all claims and demands of all Persons at any time claiming
the same or any interest therein unless both the Agent and such Guarantor
determine that the claim or demand is not material and that, consequently, such
defense would not be consistent with good business judgment. Such Guarantor will
permit any lien notices with respect to the Collateral or any portion thereof to
exist or be on file in any public office except for those in favor of the Agent
and those permitted under the terms of the Purchase Agreement.

         B.       Change in Collateral Location. Such Guarantor will not (i)
change its corporate name, (ii) change the location of its chief executive
office or establish any place of business other than those specified in Section
IIIA of Schedule A, or (iii) move or permit movement of the Collateral from the
locations specified thereon except from one such location to another such
location, unless in each case such Guarantor shall have given the Agent at least
thirty (30) days prior written notice thereof, and shall have, in advance,
executed and caused to be filed and/or delivered to the Agent any financing
statements or other documents required by the Agent to perfect the security
interest of the Agent in the Collateral in accordance with Section IV.C. hereof,
all in form and substance satisfactory to the Agent.

         C.       Additional Financing Statements. Promptly upon the reasonable
request of the Agent, such Guarantor will execute and deliver or use its best
efforts to procure any document, give any notices, execute and file any
financing statements, mortgages or other documents, all in form and substance
satisfactory to the Agent, mark any chattel paper, deliver any chattel paper or
instruments to the Agent and take any other actions that are necessary or, in
the opinion of the Agent, desirable to perfect or continue the perfection and
the first priority of the Agent's security interest in the Collateral, to
protect the Collateral against the rights, claims, or interests of third
persons, or to effect the purposes of this Guarantors Security Agreement. Such
Guarantor will pay the costs incurred in connection with any of the foregoing.

         D.       Additional Liens; Transfers. Without the prior written consent
of the Agent, such Guarantor will not, in any way, hypothecate or create or
permit to exist any lien, security interest, charge or encumbrance on or other
interest in the Collateral, other than those permitted under the terms of the
Purchase Agreement and the lien in favor of Watson pursuant to the Watson Loan
Agreement and documents relative thereto, the investors in the March 1998
Debentures and the investors in the May 1999 Debentures, and such Guarantor will
not sell, transfer, assign, pledge, collaterally assign, exchange or otherwise
dispose of the Collateral, other than the sale of Inventory in the ordinary
course of business and the sale of obsolete or worn out Equipment.
Notwithstanding the foregoing, if the proceeds of any such sale consist of
notes, instruments, documents of title, letters of credit or chattel paper, such
proceeds shall be promptly delivered to the Agent to be held as Collateral
hereunder. If the Collateral, or any part thereof, is sold, transferred,
assigned, exchanged, or otherwise disposed of in violation of these provisions,
the security interest of the Agent shall continue in such Collateral or part
thereof notwithstanding such sale, transfer, assignment, exchange or other
disposition, and such Guarantor will hold the proceeds thereof for the benefit
of the Agent, and promptly transfer such proceeds to the Agent in kind.

                                      -7-
<PAGE>
         E.       Contractual Obligations. Such Guarantor will not enter into
any contractual obligations which may restrict or inhibit the Agent's rights or
ability to sell or otherwise dispose of the Collateral or any part thereof after
the occurrence or during the continuance of an Event of Default.

         F.       Agent's Right to Protect Collateral. Upon the occurrence or
continuance of an Event of Default, the Agent shall have the right at any time
to make any payments and do any other acts the Agent may deem necessary to
protect the security interests of the Purchasers in the Collateral, including,
without limitation, the rights to pay, purchase, contest or compromise any
encumbrance, charge or lien which, in the reasonable judgment of the Agent,
appears to be prior to or superior to the security interests granted hereunder,
and appear in and defend any action or proceeding purporting to affect its
security interests in, and/or the value of, the Collateral. The Guarantors
hereby jointly and severally agree to reimburse the Agent for all payments made
and expenses incurred under this Guarantors Security Agreement including
reasonable fees, expenses and disbursements of attorneys and paralegals acting
for the Agent, including any of the foregoing payments under, or acts taken to
protect its security interests in, the Collateral, which amounts shall be
secured under this Guarantors Security Agreement, and agree they shall be bound
by any payment made or act taken by the Agent hereunder absent the Agent's gross
negligence or willful misconduct. The Agent shall have no obligation to make any
of the foregoing payments or perform any of the foregoing acts.

         G.       Further Obligations With Respect to Accounts. In furtherance
of the continuing assignment and security interest in the Accounts of such
Guarantor granted pursuant to this Guarantors Security Agreement, upon the
creation of Accounts, upon the Agent's request, such Guarantor will execute and
deliver to the Agent in such form and manner as the Agent may require, solely
for its convenience in maintaining records of Collateral, such confirmatory
schedules of Accounts, and other appropriate reports designating, identifying
and describing the Accounts as the Agent may reasonably require. In addition,
upon the Agent's request, such Guarantor shall provide the Agent with copies of
agreements with, or purchase orders from, the customers of such Guarantor and
copies of invoices to customers, proof of shipment or delivery and such other
documentation and information relating to said Accounts and other Collateral as
the Agent may reasonably require. Furthermore, upon the Agent's request, such
Guarantor shall deliver to the Agent any documents or certificates of title
issued with respect to any property included in the Collateral, and any
promissory notes, letters of credit or instruments related to or otherwise in
connection with any property included in the Collateral, which in any such case
came into the possession of such Guarantor, or shall cause the issuer thereof to
deliver any of the same directly to the Agent, in each case with any necessary
endorsements in favor of the Agent. Failure to provide the Agent with any of the
foregoing shall in no way affect, diminish, modify or otherwise limit the
security interests granted herein. Each Guarantor hereby authorizes the Agent to
regard such Guarantor's printed name or rubber stamp signature on assignment
schedules or invoices as the equivalent of a manual signature by such
Guarantor's authorized officers or agents.

         H.       Insurance. Such Guarantor agrees to maintain public liability
insurance, third party property damage insurance and replacement value insurance
on the Collateral under such policies of insurance, with such insurance
companies, in such amounts and covering such risks as

                                      -8-
<PAGE>
are at all times satisfactory to the Agent in its commercially reasonable
judgment. All policies covering the Collateral are to name the Agent as an
additional insured and the loss payee in case of loss, and are to contain such
other provisions as the Agent may reasonably require to fully protect the
Agent's interest in the Collateral and to any payments to be made under such
policies. Guarantor will provide notice to Agent prior to any change in
coverage.

         I.       Taxes. Such Guarantor agrees to pay, when due, all taxes
lawfully levied or assessed against such Guarantor or any of the Collateral
before any penalty or interest accrues thereon; provided, however, that, unless
such taxes have become a Federal tax or Employment Retirement Security Income
Act lien on any of the assets of such Guarantor, no such tax need be paid if the
same is being contested, in good faith, by appropriate proceedings promptly
instituted and diligently conducted and if an adequate reserve or other
appropriate provision shall have been made therefor as required in order to be
in conformity with generally accepted accounting principles and procedures in
effect in the United States of America.

         J.       Compliance with Laws. Such Guarantor agrees to comply in all
material respects with all requirements of law applicable to the Collateral or
any part thereof, or to the operation of its business or its assets generally,
unless such Guarantor contests in good faith, by appropriate legal,
administrative or other proceeding promptly instituted and diligently conducted,
any such requirements of law in a reasonable manner and in good faith. Such
Guarantor agrees to maintain in full force and effect, its respective licenses
and permits granted by any governmental authority as may be necessary or
advisable for such Guarantor to conduct its business in all material respects.

         K.       Maintenance of Property. Such Guarantor agrees to keep all
property useful and necessary to its business in good working order and
condition (ordinary wear and tear excepted) and not to commit or suffer any
waste with respect to any of its properties.

         L.       Environmental and Other Matters. Such Guarantor will conduct
its business so as to comply in all respects with all environmental, land use,
occupational, safety or health laws, regulations, directions, ordinances,
criteria and guidelines in all jurisdictions in which it is or may at any time
be doing business, except to the extent that such Guarantor is contesting, in
good faith by appropriate legal, administrative or other proceedings, promptly
instituted and diligently conducted, any such law, regulation, direction,
ordinance, criteria, guideline, or interpretation thereof or application
thereof; provided, further, that such Guarantor shall comply with the order of
any court or other governmental authority relating to such laws unless such
Guarantor shall currently be prosecuting an appeal, proceedings for review or
administrative proceedings and shall have secured a stay of enforcement or
execution or other arrangement postponing enforcement or execution pending such
appeal, proceedings for review or administrative proceedings.

         M.       Intellectual Property. With respect to each item of its
intellectual property, each of the Guarantors agrees to take, at its expense,
all necessary steps, including, without limitation, in the U.S. Patent and
Trademark Office, the U.S. Copyright Office and any other governmental
authority, to (i) maintain the validity and enforceability of such intellectual
property and maintain such intellectual property in full force and effect, and
(ii) pursue the registration and maintenance of each patent, trademark, or
copyright registration or application,

                                      -9-
<PAGE>
now or hereafter included in such intellectual property Collateral of the
Guarantors, including, without limitation, the payment of required fees and
taxes, the filing of responses to office actions issued by the U.S. Patent and
Trademark Office, the U.S. Copyright Office or other governmental authorities,
the filing of applications for renewal or extension, the filing of affidavits
under Sections 8 and 15 of the U.S. Trademark Act, the filing of divisional,
continuation, continuation-in-part, reissue and renewal applications or
extensions, the payment of maintenance fees and the participation in
interference, reexamination, opposition, cancellation, infringement and
misappropriation proceedings. Neither the Guarantors nor the Grantor shall,
without the prior written consent of the Agent, discontinue use of or otherwise
abandon any intellectual property Collateral, or abandon any right to file an
application for any patent, trademark or copyright, unless the Guarantors shall
have previously determined that such use or the pursuit or maintenance of such
intellectual property is no longer desirable in the conduct of the Guarantors'
business and that the loss thereof would not be reasonably likely to have a
Material Adverse Effect, in which case, the Guarantors will give prompt notice
of any such abandonment to the Agent.

         N.       Further Assurances. Such Guarantor shall take all such further
actions and execute all such further documents and instruments (including, but
not limited to, collateral assignments of Intellectual Property and Intangibles
or any portion thereof) as the Agent may at any time reasonably determine in its
sole discretion to be necessary or desirable to further carry out and consummate
the transactions contemplated by the Purchase Agreement and the documentation
relating thereto, including this Guarantors Security Agreement, and to perfect
or protect the liens (and the priority status thereof) of the Agent in the
Collateral.

         SECTION V. REMEDIES.

         A.       Obtaining the Collateral Upon Default. If any Event of Default
shall have occurred and be continuing, then and in every such case, subject to
any mandatory requirements of applicable law then in effect, the Agent, in
addition to any rights now or hereafter existing under applicable law and
subject to the Subordination Agreement, shall have all rights as a secured
creditor under the Uniform Commercial Code in all relevant jurisdictions and
may:

                  (i)      personally, or by agents or attorneys, immediately
         retake possession of the Collateral or any part thereof, from any
         Guarantor or any other Person who then has possession of any part
         thereof, with or without notice or process of law, and for that purpose
         may enter upon such Guarantor's premises where any of the Collateral is
         located and remove the same and use in connection with such removal
         any and all services, supplies, aids and other facilities of such
         Guarantor;

                  (ii)     instruct the obligor or obligors on any agreement,
         instrument or other obligation (including, without limitation, the
         Accounts) constituting the Collateral to make any payment required by
         the terms of such instrument or agreement directly to the Agent;

                  (iii)    withdraw all monies, securities and instruments held
         pursuant to any pledge arrangement for application to the Obligations;

                                      -10-
<PAGE>
                  (iv)     sell, assign or otherwise liquidate, or direct any
         Guarantor to sell, assign or otherwise liquidate, any or all of the
         Collateral or any part thereof, and take possession of the proceeds of
         any such sale or liquidation;

                  (v)      take possession of the Collateral or any part
         thereof, by directing any Guarantor in writing to deliver the same to
         the Agent at any place or places designated by the Agent, in which
         event such Guarantor shall at its own expense:

                           a.       forthwith cause the same to be moved to the
                  place or places so designated by the Agent and there delivered
                  to the Agent,

                           b.       store and keep any Collateral so delivered
                  to the Agent at such place or places pending further action by
                  the Agent as provided in Section V.B., and

                           c.       while the Collateral shall be so stored and
                  kept, provide such guards and maintenance services as shall be
                  necessary to protect the same and to preserve and maintain the
                  Collateral in good condition;

                  it being understood that any Guarantor's obligation to so
                  deliver the Collateral is of the essence of this Guarantors
                  Security Agreement and that, accordingly, upon application to
                  a court of equity having jurisdiction, the Agent shall be
                  entitled to a decree requiring specific performance by such
                  Guarantor of said obligation.

         B.       Disposition of the Collateral. Subject to the Subordination
Agreement any collateral repossessed by the Agent under or pursuant to Section
V.A. and any other Collateral whether or not so repossessed by the Agent, may be
sold, assigned, leased or otherwise disposed of under one or more contracts or
as an entirety, and without the necessity of gathering at the place of sale the
property to be sold, and in general in such manner, at such time or times, at
such place or places and on such terms as the Agent may, in compliance with any
mandatory requirements of applicable law, determine to be commercially
reasonable. Any of the Collateral may be sold, leased or otherwise disposed of,
in the condition in which the same existed when taken by the Agent or after any
overhaul or repair which the Agent shall determine to be commercially
reasonable. Any such disposition which shall be a private sale or other private
proceedings permitted by such requirements shall be made upon not less than ten
(10) days' written notice to such Guarantor specifying the time at which such
disposition is to be made and the intended sale price or other consideration
therefor, and shall be subject, for the ten (10) days after the giving of such
notice, to the right of such Guarantor or any nominee of such Guarantor to
acquire the Collateral involved at a price or for such other consideration at
least equal to the intended sale price or other consideration so specified. Any
such disposition which shall be a public sale permitted by such requirements
shall be made upon not less than ten (10) days' written notice to such Guarantor
specifying the time and place of such sale and, in the absence of applicable
requirements of law, shall be by public auction (which may, at the option of the
Agent, be subject to reserve), after publication at least once in The New York
Times not less than ten (10) days prior to the date of sale. If The New York
Times is not then being

                                      -11-
<PAGE>
published, publication may be made in lieu thereof in any newspaper then being
circulated in the City of New York, New York, as the Agent may elect. All
requirements of reasonable notice under this Section V.B. shall be met if such
notice is mailed, postage prepaid at least ten (10) days before the time of such
sale or disposition, to the Guarantor at its address set forth herein or such
other address as the Guarantor may have, in writing, provided to the Agent. The
Agent may, if it deems it reasonable, postpone or adjourn any sale of any
collateral from time to time by an announcement at the time and place of the
sale to be so postponed or adjourned without being required to give a new notice
of sale. The proceeds realized from the sale of any Collateral shall be applied
as follows: first, to the reasonable costs, expenses and attorneys' fees and
expenses incurred by Agent for collection and for acquisition, completion,
protection, removal, storage, sale and delivery of the Collateral; second, to
interest due on any of the Obligations and any fees payable under this
Agreement; and third, to the principal of the Obligations. If any deficiency
shall arise, Guarantors shall remain liable to Agent and Purchasers therefor.

         C.       Power of Attorney. Each Guarantor hereby irrevocably
authorizes and appoints the Agent, or any Person or agent the Agent may
designate, as such Guarantor's attorney-in-fact, at such Guarantor's cost and
expense, to exercise all of the following powers upon and at any time after the
occurrence and during the continuance of an Event of Default, which powers,
being coupled with an interest, shall be irrevocable until all of the
Obligations owing by such Guarantor shall have been paid and satisfied in full:

                  (i)      accelerate or extend the time of payment, compromise,
         issue credits, bring suit or administer and otherwise collect Accounts
         or proceeds of any Collateral;

                  (ii)     receive, open and dispose of all mail addressed to
         such Guarantor and notify postal authorities to change the address for
         delivery thereof to such address as the Agent may designate;

                  (iii)    give customers indebted on Accounts notice of the
         Agent's interest therein, and/or to instruct such customers to make
         payment directly to the Agent for such Guarantor's account;

                  (iv)     convey any item of Collateral to any purchaser
         thereof;

                  (v)      give any notices or record any liens under
         Section IV.C. hereof; and

                  (vi)     make any payments or take any acts under
         Section IV.F. hereof.

The Agent's authority under this Section V.C. shall include, without limitation,
the authority to execute and give receipt for any certificate of ownership or
any document, transfer title to any item of Collateral, sign such Guarantor's
name on all financing statements or any other documents deemed necessary or
appropriate to preserve, protect or perfect the security interest in the
Collateral and to file the same, prepare, file and sign such Guarantor's name on
any notice of lien, assignment or satisfaction of lien or similar document in
connection with any Account and prepare, file and sign such Guarantor's name on
a proof of claim in bankruptcy or similar document against any customer of such
Guarantor, and to take any other actions arising from or incident to the rights,
powers and

                                      -12-
<PAGE>
remedies granted to the Agent in this Guarantors Security Agreement. This power
of attorney is coupled with an interest and is irrevocable by such Guarantor.

         D.       Waiver of Claims. Except as otherwise provided in this
Guarantors Security Agreement, EACH GUARANTOR HEREBY WAIVES, TO THE EXTENT
PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE
AGENT'S TAKING POSSESSION OF OR DISPOSING OF ANY OF THE COLLATERAL, INCLUDING,
WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT
REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH ANY GUARANTOR WOULD OTHERWISE HAVE
UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE, and
each Guarantor hereby further waives, to the extent permitted by law:

                  (i)      all damages occasioned by such taking of possession
                  except any damages which are the direct result of the Agent's
                  gross negligence or willful misconduct;

                  (ii)     all other requirements as to the time, place and
                  terms of sale or other requirements with respect to the
                  enforcement of the Agent's rights hereunder, except as
                  expressly provided herein; and

                  (iii)    all rights of redemption, appraisement, valuation,
                  stay, extension or moratorium now or hereafter in force under
                  any applicable law in order to prevent or delay the
                  enforcement of this Guarantors Security Agreement or the
                  absolute sale of the Collateral or any portion thereof, and
                  such Guarantor, for itself and all who may claim under it,
                  insofar as it or they now or hereafter lawfully may, hereby
                  waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon
any Collateral shall operate to divest all right, title, interest, claim and
demand, either at law or in equity, of such Guarantor therein and thereto, and
shall be a perpetual bar both at law and in equity against such Guarantor and
against any and all persons claiming or attempting to claim the Collateral so
sold, optioned or realized upon, or any part thereof, from, through and under
such Guarantor.

         E.       Remedies Cumulative. Each and every right, power and remedy
hereby specifically given to the Agent shall be in addition to every other
right, power and remedy specifically given under this Guarantors Security
Agreement, under the Purchase Agreement or under other documentation relating
thereto or now or hereafter existing at law or in equity, or by statute, and
each and every right, power and remedy whether specifically herein given or
otherwise existing may be exercised from time to time or simultaneously and as
often and in such order as may be deemed expedient by the Agent. All such
rights, powers and remedies shall be cumulative and the exercise or the
beginning of exercise of one shall not be deemed a waiver of the right to
exercise of any other or others. No delay or omission of the Agent in the
exercise of any such right, power or remedy and no renewal or extension of any
of the Obligations shall impair any such right, power or remedy or shall be
construed to be a waiver of any Default or Event of Default or any acquiescence
therein.

         M.       Counterparts. This Guarantors Security Agreement may be
executed in one or more counterparts, each of which shall be deemed an original
but all of which shall together constitute one and the same agreement.

         N.       GOVERNING LAW. This Guarantors Security Agreement and the
rights of the parties hereunder shall be governed by, and construed in
accordance with, the laws of the State of New York wherein the terms of this

permitted by law any rule of law that would cause the application of the laws of
any jurisdiction other than the State of New York.

         O.       SUBMISSION TO JURISDICTION.

         (i)      Each of the parties hereto hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of any New York State court or United States Federal court sitting
in New York City, and any appellate court from any thereof, in any action or
proceeding arising our of or relating to this Guarantors Security Agreement or
any of the other Transaction Documents (as such term is defined in the
Subordination Agreement) to which it is a party, or for recognition or
enforcement of any judgment, and each of the parties hereto irrevocably and
unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in any such New York State court or, to
the fullest extent permitted by law, in such United States Federal court. Each
of the parties hereto agrees that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the right that any party may otherwise have to bring any action or
proceeding relating to this Guarantors Security Agreement or any of the other
Transaction Documents in the courts of any other jurisdiction.

         (ii)     Each of the parties hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or in relation to this Guarantors Security
Agreement or any other Transaction Document to which it is a party in any such
New York State or United States Federal court sitting in New York City. Each of
the parties hereto hereby irrevocably waives, to the fullest extent permitted by
law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court.

REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO SUCH GUARANTOR AT ITS ADDRESS
SET FORTH IN SECTION VI.A. HEREOF.

         Q.       LIMITATION OF LIABILITY. THE AGENT SHALL NOT HAVE ANY
LIABILITY TO ANY GUARANTOR (WHETHER SOUNDING IN TORT, CONTRACT, OR OTHERWISE)
FOR LOSSES SUFFERED BY ANY GUARANTOR IN CONNECTION WITH, ARISING OUT OF, OR IN
ANY WAY RELATED TO THE TRANSACTIONS OR RELATIONSHIPS CONTEMPLATED BY THIS
GUARANTORS SECURITY AGREEMENT,

                                      -16-
<PAGE>
OR ANY ACT, OMISSION OR EVENT OCCURRING IN CONNECTION THEREWITH, UNLESS IT IS
DETERMINED BY A FINAL AND NONAPPEALABLE JUDGMENT OR COURT ORDER BINDING ON THE
AGENT, THAT THE LOSSES WERE THE RESULT OF ACTS OR OMISSIONS CONSTITUTING GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT.

         R.       Delays; Partial Exercise of Remedies. No delay or omission of
the Agent to exercise any right or remedy hereunder, whether before or after the
happening of any Event of Default, shall impair any such right or shall operate
as a waiver thereof or as a waiver of any such Event of Default. No single or
partial exercise by the Agent of any right or remedy shall preclude any other or
further exercise thereof, or preclude any other right or remedy.

         S.       JURY TRIAL. EACH OF THE GUARANTORS AND THE AGENT HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR
RELATING TO ANY TRANSACTION DOCUMENT OR THE ACTIONS OF ANY PARTY IN THE
NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

         T.       Subject To Subordination Agreement. Notwithstanding anything
to the contrary contained herein, the rights and remedies of agent and the
purchases, and the obligations of the guarantors, under this guarantors general
security agreement are subject to the subordination agreement, as it may be
amended, supplemented or otherwise modified from time to time.
