                                       2

        2. Registration.

           a. Mandatory Registration. The Company shall prepare, and, as soon as
practicable but in no event later than May 22, 2002 (the "Filing Deadline"),
file with the SEC the Registration Statement on Form S-3 covering the resale of
all of the Registrable Securities. In the event that Form S-3 is unavailable for
such a registration, the Company shall use such other form as is available for
such a registration, subject to the provisions of Section 2(d). The Registration
Statement prepared pursuant hereto shall register for resale at least 12,086,209
shares of Common Stock, subject to adjustment for any stock split, stock
dividend, recapitalization, exchange or similar event. The Company shall use its
reasonable best efforts to have the Registration Statement declared effective by
the SEC as soon as practicable, but in no event later than September 4, 2002
(the "Effectiveness Deadline").

           b. Allocation of Registrable Securities. The initial number of
Registrable Securities included in any Registration Statement and each increase
in the number of Registrable Securities included therein shall be allocated pro
rata among the Investors based on the number of Registrable Securities held by
each Investor at the time the Registration Statement covering such initial
number of Registrable Securities or increase thereof is declared effective by
the SEC. In the event that an Investor sells or otherwise transfers any of such
Investor's Registrable Securities then remaining unsold, each transferee shall
be allocated a pro rata portion of the then remaining number of Registrable
Securities included in such Registration Statement for such transferor. Any
shares of Common Stock included in a Registration Statement and which remain
allocated to any Person which ceases to hold any Registrable Securities covered
by such Registration Statement shall be allocated to the remaining Investors,
pro rata based on the number of Registrable Securities then held by such
Investors which are covered by such Registration Statement. In no event shall
the Company include any securities other than Registrable Securities on any
Registration Statement without the prior written consent of Buyers holding at
least a majority of the Registrable Securities; provided, however, that,
notwithstanding the foregoing, the Company may include on any Registration
Statement, without the prior written consent of the Buyers, shares of Common
Stock issued to vendors of the Company in an amount not to exceed 2,000,000
shares.

           c. Legal Counsel. Subject to Section 5 hereof, the Buyers holding at
least a majority of the Registrable Securities shall have the right to select
one legal counsel to review and oversee any registration pursuant to this
Section 2 ("Legal Counsel"), which shall be Schulte Roth & Zabel LLP or such
other counsel as thereafter designated by the holders of at least a majority of
the Registrable Securities. The Company and Legal Counsel shall reasonably
cooperate with each other in performing the Company's obligations under this
Agreement.

           d. Ineligibility for Form S-3. In the event that Form S-3 is not
available for the registration of the resale of Registrable Securities
hereunder, the Company shall (i) register the resale of the Registrable
Securities on another appropriate form reasonably acceptable to the holders of
at least a majority of the Registrable Securities and (ii) undertake to register
the Registrable Securities on Form S-3 as soon as such form is available,
provided that the Company shall maintain the effectiveness of the Registration
Statement then in effect until such time as a Registration Statement on Form S-3
covering the Registrable Securities has been declared effective by the SEC.

                                       3
<PAGE>

           e. Sufficient Number of Shares Registered. In the event the number of
shares available under a Registration Statement filed pursuant to Section 2(a)
is insufficient to cover all of the Registrable Securities required to be
covered by such Registration Statement or an Investor's allocated portion of the
Registrable Securities pursuant to Section 2(b), the Company shall amend the
applicable Registration Statement, or file a new Registration Statement (on the
short form available therefor, if applicable), or both, so as to cover at least
125% of the number of such Registrable Securities as of the trading day
immediately preceding the date of the filing of such amendment or new
Registration Statement, in each case, as soon as practicable, but in any event
not later than fifteen (15) business days after the necessity therefor arises.
The Company shall use its reasonable best efforts to cause such amendment and/or
new Registration Statement to become effective as soon as practicable following
the filing thereof. For purposes of the foregoing provision, the number of
shares available under a Registration Statement shall be deemed "insufficient to
cover all of the Registrable Securities" if at any time the number of
Registrable Securities issued or issuable upon conversion of the Convertible
Debentures and upon exercise of the Warrants, if any, covered by such
Registration Statement is greater than the quotient determined by dividing (i)
number of shares of Common Stock available for resale under such Registration
Statement by (ii) 1.1. The calculation set forth in the foregoing sentence shall
be made without regard to any limitations on the conversion of the Convertible
Debentures or the exercise of the Warrants and such calculation shall assume
that the Convertible Debentures and the Warrants are then convertible into
shares of Common Stock and are issuable at the then prevailing Conversion Rate
(as defined in the Convertible Debentures) or Warrant Exercise Price, as
applicable.

           f. Effect of Failure to File and Obtain and Maintain Effectiveness of
Registration Statement. If (i) a Registration Statement covering all the
Registrable Securities required to be covered thereby and required to be filed
by the Company pursuant to this Agreement is (A) not filed with the SEC on or
before the respective Filing Deadline or (B) not declared effective by the SEC
on or before the respective Effectiveness Deadline or (ii) on any day after such
Registration Statement has been declared effective by the SEC sales of all the
Registrable Securities required to be included on such Registration Statement
cannot be made (other than during an Allowable Grace Period (as defined in
Section 3(r)) pursuant to such Registration Statement (including, without
limitation, because of a failure to keep such Registration Statement effective,
to disclose such information as is necessary for sales to be made pursuant to
such Registration Statement or to register sufficient shares of Common Stock)
(the "Selling Prohibition"), then, as partial relief for the damages to any
holder by reason of any such delay in or reduction of its ability to sell the
underlying shares of Common Stock (which remedy shall not be exclusive of any
other remedies available at law or in equity), the Company shall pay to each
holder of Convertible Debentures relating to such Registration Statement an
amount in cash equal to the product of (i) the Penalty Amount applicable to such
Investor multiplied by (ii) the product of (I) 0.0005 multiplied by (II) the sum
of (x) the number of days after the applicable Filing Deadline that the
Registration Statement is not filed with the SEC, plus (y) the number of days
after the applicable Effectiveness Deadline that the Registration Statement is
not declared effective by the SEC, plus (z) the number of days, in each
instance, after the Registration Statement has been declared effective by the
SEC that such Registration Statement is not available (other than during an
Allowable Grace Period) for the sale of all the Registrable Securities required
to be included on such Registration Statement. The payments to

                                       4
<PAGE>

which a holder shall be entitled pursuant to this Section 2(f) are referred to
herein as "Registration Delay Payments." Registration Delay Payments shall be
paid on the earlier of (I) the last day of the calendar month during which such
Registration Delay Payments are incurred and (II) the third Business Day after
the event or failure giving rise to the Registration Delay Payments is cured. In
the event the Company fails to make Registration Delay Payments in a timely
manner, such Registration Delay Payments shall bear interest at the rate of 1.5%
per month (prorated for partial months) until paid in full.

        3. Related Obligations.

        At such time as the Company is obligated to file a Registration
Statement with the SEC pursuant to Section 2(a), 2(d) or 2(e), the Company will
use its reasonable best efforts to effect the registration of the Registrable
Securities in accordance with the intended method of disposition thereof and,
pursuant thereto, the Company shall have the following obligations:

           a. The Company shall promptly prepare and file with the SEC a
Registration Statement with respect to the Registrable Securities (but in no
event later than the applicable Filing Deadline) and use its reasonable best
efforts to cause such Registration Statement relating to the Registrable
Securities required to be covered thereby to become effective as soon as
practicable after such filing (but in no event later than the applicable
Effectiveness Deadline). The Company shall keep each Registration Statement
effective pursuant to Rule 415 at all times until the earlier of (i) the date as
of which the Investors may sell all of the Registrable Securities covered by
such Registration Statement without restriction pursuant to Rule 144(k) (or
successor thereto) promulgated under the 1933 Act or (ii) the date on which the
Investors shall have sold all the Registrable Securities covered by such
Registration Statement (the "Registration Period"), which Registration Statement
(including any amendments or supplements thereto and prospectuses contained
therein) shall not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein, or necessary to make the
statements therein, in the light of the circumstances in which they were made,
not misleading. The term "reasonable best efforts" as used in this Section 3(a)
shall mean, among other things, that the Company shall submit to the SEC, within
two (2) Business Days after the Company learns that no review of a particular
Registration Statement will be made by the staff of the SEC or that the staff
has no further comments on the Registration Statement, as the case may be, and
the approval of Legal Counsel pursuant to Section 3(c), a request for
acceleration of effectiveness of such Registration Statement to a time and date
not later than 48 hours after the submission of such request.

           b. Subject to Section 3(r), the Company shall prepare and file with
the SEC such amendments (including post-effective amendments) and supplements to
a Registration Statement and the prospectus used in connection with such
Registration Statement, which prospectus is to be filed pursuant to Rule 424
promulgated under the 1933 Act, as may be necessary to keep such Registration
Statement effective at all times during the Registration Period, and, during
such period, comply with the provisions of the 1933 Act with respect to the
disposition of all Registrable Securities of the Company covered by such
Registration Statement until the end of the Registration Period. In the case of
amendments and supplements to a Registration Statement which are required to be
filed pursuant to this Agreement (including pursuant to this Section 3(b)) by
reason of the Company filing a report on Form 10-K, Form 10-

                                       5
<PAGE>

Q or Form 8-K or any analogous report under the Securities Exchange Act of 1934,
as amended (the "1934 Act"), the Company shall have incorporated such report by
reference into such Registration Statement, if applicable, or shall file such
amendments or supplements with the SEC on the same day on which the 1934 Act
report is filed which created the requirement for the Company to amend or
supplement such Registration Statement.

           c. The Company shall (A) permit Legal Counsel to review and comment
upon (i) a Registration Statement at least three (3) Business Days prior to its
filing with the SEC and (ii) all amendments and supplements to all Registration
Statements (except for Annual Reports on Form 10-K, Quarterly Reports on Form
10-Q and Current Reports on Form 8-K and any similar or successor reports)
within a reasonable number of days prior to their filing with the SEC. The
Company shall furnish to Legal Counsel, without charge, (i) copies of any
correspondence from the SEC or the staff of the SEC to the Company or its
representatives relating to any Registration Statement, (ii) promptly after the
same is prepared and filed with the SEC, one copy of any Registration Statement
and any amendment(s) thereto, including financial statements and schedules, all
documents incorporated therein by reference, if requested by an Investor, and
all exhibits, provided that if such Registration Statement and related documents
are filed with the SEC through EDGAR and are available to the Investors via
EDGAR then no such deliveries shall be required and (iii) upon the effectiveness
of any Registration Statement, one copy of the prospectus included in such
Registration Statement and all amendments and supplements thereto. The Company
shall reasonably cooperate with Legal Counsel in performing the Company's
obligations pursuant to this Section 3.

           d. The Company shall furnish to each Investor whose Registrable
Securities are included in any Registration Statement, without charge, (i)
promptly after the same is prepared and filed with the SEC, at least one copy of
such Registration Statement and any amendment(s) thereto, including financial
statements and schedules, all documents incorporated therein by reference, if
requested by an Investor, all exhibits and each preliminary prospectus, provided
that if such Registration Statement and related documents are filed with the SEC
through EDGAR and are available to the Investors via EDGAR then no such
deliveries shall be required, (ii) upon the effectiveness of any Registration
Statement, ten (10) copies of the prospectus included in such Registration
Statement and all amendments and supplements thereto (or such other number of
copies as such Investor may reasonably request) and (iii) such other documents,
including copies of any preliminary or final prospectus, as such Investor may
reasonably request from time to time in order to facilitate the disposition of
the Registrable Securities owned by such Investor.

           e. Subject to Section 3(r), the Company shall use its reasonable best
efforts to (i) register and qualify, unless an exemption from registration and
qualification applies, the resale by Investors of the Registrable Securities
covered by a Registration Statement under such other securities or "blue sky"
laws of all applicable jurisdictions in the United States, (ii) prepare and file
in those jurisdictions, such amendments (including post-effective amendments)
and supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and
qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify

                                       6
<PAGE>

the Registrable Securities for sale in such jurisdictions; provided, however,
that the Company shall not be required in connection therewith or as a condition
thereto to (x) qualify to do business in any jurisdiction where it would not
otherwise be required to qualify but for this Section 3(e), (y) subject itself
to general taxation in any such jurisdiction, or (z) file a general consent to
service of process in any such jurisdiction. The Company shall promptly notify
Legal Counsel and each Investor who holds Registrable Securities of the receipt
by the Company of any notification with respect to the suspension of the
registration or qualification of any of the Registrable Securities for sale
under the securities or "blue sky" laws of any jurisdiction in the United States
or its receipt of actual notice of the initiation or threatening of any
proceeding for such purpose.

           f. The Company shall notify Legal Counsel and each Investor in
writing of the happening of any event, as promptly as practicable after becoming
aware of such event, as a result of which the prospectus included in a
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omission to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading (provided that in no event shall such
notice contain any material, nonpublic information), and, subject to Section
3(r), promptly prepare a supplement or amendment to such Registration Statement
to correct such untrue statement or omission, and deliver ten (10) copies of
such supplement or amendment to Legal Counsel and each Investor (or such other
number of copies as Legal Counsel or such Investor may reasonably request). The
Company shall also promptly notify Legal Counsel and each Investor in writing
(i) when a prospectus or any prospectus supplement or post-effective amendment
has been filed, and when a Registration Statement or any post-effective
amendment has become effective (notification of such effectiveness shall be
delivered to Legal Counsel and each Investor by facsimile on the same day of
such effectiveness and by overnight mail), (ii) of any request by the SEC for
amendments or supplements to a Registration Statement or related prospectus or
related information, and (iii) of the Company's reasonable determination that a
post-effective amendment to a Registration Statement would be appropriate
(provided that in no event shall such notice contain any material, nonpublic
information).

           g. Subject to Section 3(r), the Company shall use its reasonable best
efforts to prevent the issuance of any stop order or other suspension of
effectiveness of a Registration Statement, or the suspension of the
qualification of any of the Registrable Securities for sale in any jurisdiction
and, if such an order or suspension is issued, to obtain the withdrawal of such
order or suspension at the earliest possible moment and to notify Legal Counsel
and each Investor who holds Registrable Securities being sold of the issuance of
such order and the resolution thereof or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose.

           h. If an Investor has been deemed or may be deemed an underwriter
under the 1933 Act and the Investor reasonably believes it needs to avail itself
of the due diligence defense under the 1933 Act, at the reasonable request of
any Investor, the Company shall furnish to such Investor, on the date of the
effectiveness of the Registration Statement and thereafter from time to time on
such dates as an Investor may reasonably request (i) a letter, dated such date,
from the Company's independent certified public accountants in form and

                                       7
<PAGE>

substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the Investors, and
(ii) an opinion, dated as of such date, of counsel representing the Company for
purposes of such Registration Statement, in form, scope and substance as is
customarily given in an underwritten public offering, addressed to the
Investors.

           i. The Company shall make available for inspection by (i) any
Investor, (ii) Legal Counsel and (iii) one firm of accountants or other agents
retained by the Investors (collectively, the "Inspectors"), after execution by
the Investors or the Inspectors of a confidentiality agreement (with appropriate
trading restrictions), all pertinent financial and other records, and pertinent
corporate documents and properties of the Company (collectively, the "Records"),
as shall be reasonably deemed necessary by each Inspector, and cause the
Company's officers, directors and employees to supply all information which any
Inspector may reasonably request; provided, however, that each Inspector shall
agree to hold in strict confidence and shall not make any disclosure (except to
an Investor) or use of any Record or other information which the Company
determines in good faith to be confidential, and of which determination the
Inspectors are so notified, unless (a) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in any Registration
Statement or is otherwise required under the 1933 Act, (b) the release of such
Records is ordered pursuant to a final, non-appealable subpoena or order from a
court or government body of competent jurisdiction, or (c) the information in
such Records has been made generally available to the public other than by
disclosure in violation of this or any other agreement of which the Inspector
has knowledge. Each Investor agrees that it shall, upon learning that disclosure
of such Records is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at its expense, to undertake appropriate action to prevent
disclosure of, or to obtain a protective order for, the Records deemed
confidential. Nothing herein (or in any other confidentiality agreement between
the Company and any Investor) shall be deemed to limit the Investors' ability to
sell Registrable Securities in a manner which is otherwise consistent with
applicable laws and regulations.

           j. The Company shall hold in confidence and not make any disclosure
of information concerning an Investor provided to the Company unless (i)
disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement. The Company agrees that it shall, upon learning that disclosure of
such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Investor and allow such Investor, at the Investor's
expense, to undertake appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

           k. The Company shall use its reasonable best efforts either to (i)
cause all the Registrable Securities covered by a Registration Statement to be
listed on each securities exchange on which securities of the same class or
series issued by the Company are

                                       8
<PAGE>

then listed, if any, if the listing of such Registrable Securities is then
permitted under the rules of such exchange, or (ii) secure designation and
quotation of all the Registrable Securities covered by a Registration Statement
on the Nasdaq National Market, or (iii) if, despite the Company's reasonable
best efforts to satisfy the preceding clause (i) or (ii), the Company is
unsuccessful in satisfying the preceding clause (i) or (ii), to secure the
inclusion for quotation on The Nasdaq SmallCap Market for such Registrable
Securities and, without limiting the generality of the foregoing, to use its
reasonable best efforts to arrange for at least two market makers to register
with the National Association of Securities Dealers, Inc. ("NASD") as such with
respect to such Registrable Securities. The Company shall pay all fees and
expenses in connection with satisfying its obligation under this Section 3(k).

           l. The Company shall cooperate with the Investors who hold
Registrable Securities being offered and, to the extent applicable, facilitate
the timely preparation and delivery of certificates (not bearing any restrictive
legend) representing the Registrable Securities to be offered pursuant to a
Registration Statement and enable such certificates to be in such denominations
or amounts, as the case may be, as the Investors may reasonably request and
registered in such names as the Investors may request.

           m. If requested by an Investor, the Company shall (i) as soon as
practicable incorporate in a prospectus supplement or post-effective amendment
such information as an Investor reasonably requests to be included therein
relating to the sale and distribution of Registrable Securities, including,
without limitation, information with respect to the number of Registrable
Securities being offered or sold, the purchase price being paid therefor and any
other terms of the offering of the Registrable Securities to be sold in such
offering; (ii) as soon as practicable make all required filings of such
prospectus supplement or post-effective amendment after being notified of the
matters to be incorporated in such prospectus supplement or post-effective
amendment; and (iii) as soon as practicable, supplement or make amendments to
any Registration Statement if reasonably requested by an Investor holding any
Registrable Securities.

           n. The Company shall use its reasonable best efforts to cause the
Registrable Securities covered by a Registration Statement to be registered with
or approved by such other governmental agencies or authorities as may be
necessary to consummate the disposition of such Registrable Securities.

           o. The Company shall make generally available to its security holders
as soon as practical, but not later than ninety (90) days after the close of the
period covered thereby, an earnings statement (in form complying with, and in
the manner provided by, the provisions of Rule 158 under the 1933 Act) covering
a twelve-month period beginning not later than the first day of the Company's
fiscal quarter next following the effective date of a Registration Statement.

           p. The Company shall otherwise use its reasonable best efforts to
comply with all applicable rules and regulations of the SEC in connection with
any registration hereunder.

                                       9
<PAGE>

           q. Within two (2) Business Days after a Registration Statement which
covers Registrable Securities is ordered effective by the SEC, the Company shall
deliver, and shall cause legal counsel for the Company to deliver, to the
transfer agent for such Registrable Securities (with copies to the Investors
whose Registrable Securities are included in such Registration Statement)
confirmation that such Registration Statement has been declared effective by the
SEC in the form attached hereto as Exhibit A.

           r. Notwithstanding anything to the contrary herein, at any time after
the Registration Statement has been declared effective by the SEC, the Company
may delay the disclosure of material non-public information concerning the
Company the disclosure of which at the time is not, in the good faith opinion of
the Board of Directors of the Company and its counsel, in the best interest of
the Company and, in the opinion of counsel to the Company, otherwise required (a
"Grace Period"); provided, that the Company shall promptly (i) notify the
Investors in writing of the existence of material non-public information giving
rise to a Grace Period (provided that in each notice the Company will not
disclose the content of such material non-public information to the Investors)
and the date on which the Grace Period will begin (or has begun), and (ii)
notify the Investors in writing of the date on which the Grace Period ends; and,
provided further, that no Grace Period shall exceed twenty (20) consecutive days
and during any three hundred sixty five (365) day period such Grace Periods
shall not exceed an aggregate of forty-five (45) days and the first day of any
Grace Period must be at least two (2) trading days after the last day of any
prior Grace Period (an "Allowable Grace Period"). For purposes of determining
the length of a Grace Period above, the Grace Period shall begin on and include
the date the Investors receive the notice referred to in clause (i) and shall
end on the date the date referred to in the notice referred to in clause (ii).
The provisions of Section 3(g) hereof shall not be applicable during the period
of any Allowable Grace Period. Upon expiration of the Grace Period, the Company
shall again be bound by the first sentence of Section 3(f) with respect to the
information giving rise thereto unless such material non-public information is
no longer applicable.

        4. Obligations Of The Investors.

           a. At least seven (7) days prior to the first anticipated filing date
of a Registration Statement, the Company shall notify each Investor in writing
of the information the Company requires from each such Investor if such Investor
elects to have any of such Investor's Registrable Securities included in such
Registration Statement. It shall be a condition precedent to the obligations of
the Company to complete the registration pursuant to this Agreement with respect
to the Registrable Securities of a particular Investor that such Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the
effectiveness of the registration of such Registrable Securities and shall
execute such documents in connection with such registration as the Company may
reasonably request.

           b. Each Investor, by such Investor's acceptance of the Registrable
Securities, agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of any Registration
Statement hereunder, unless such Investor has notified the Company in writing of
such Investor's election to exclude all of such Investor's Registrable
Securities from such Registration Statement.

                                       10
<PAGE>

           c. Each Investor agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3(g) or
the first sentence of 3(f), such Investor will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s)
covering such Registrable Securities until such Investor's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 3(g) or the
first sentence of 3(f) or receipt of notice that no supplement or amendment is
required. Notwithstanding anything to the contrary, the Company shall cause its
transfer agent to deliver unlegended shares of Common Stock to a transferee of
an Investor in accordance with the terms of the Securities Purchase Agreement in
connection with any sale of Registrable Securities with respect to which an
Investor has entered into a contract for sale prior to the Investor's receipt of
a notice from the Company of the happening of any event of the kind described in
Section 3(g) or the first sentence of 3(f) and for which the Investor has not
yet settled.

           d. Each Investor agrees that it will comply with any prospectus
delivery requirements pursuant to the 1933 Act.

        5. Expenses Of Registration.

        All reasonable expenses, other than underwriting discounts and
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualifications fees, printers and accounting fees, and
fees and disbursements of counsel for the Company shall be paid by the Company.
The Company shall also reimburse the Investors for the fees and disbursements of
Legal Counsel in connection with registration, filing or qualification pursuant
to Sections 2 and 3 of this Agreement which amount shall be limited to $10,000
for the Registration Statement.

        6. Indemnification.

        In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

           a. To the fullest extent permitted by law, the Company will, and
hereby does, indemnify, hold harmless and defend each Investor, the directors,
officers, partners, employees, agents, representatives of, and each Person, if
any, who controls any Investor within the meaning of the 1933 Act or the 1934
Act (each, an "Indemnified Person"), against any losses, claims, damages,
liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys'
fees, amounts paid in settlement or expenses, joint or several, (collectively,
"Claims") incurred in investigating, preparing or defending any action, claim,
suit, inquiry, proceeding, investigation or appeal taken from the foregoing by
or before any court or governmental, administrative or other regulatory agency,
body or the SEC, whether pending or threatened, whether or not an indemnified
party is or may be a party thereto ("Indemnified Damages"), to which any of them
may become subject insofar as such Claims (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon: (i)
any untrue statement or alleged untrue statement of a material fact in a
Registration Statement or any post-effective amendment thereto or in any filing
made in connection with the qualification of the offering under the securities
or other "blue sky" laws of any jurisdiction in which Registrable Securities are
offered ("Blue Sky Filing"), or the omission or alleged omission to state a
material fact required to be

                                       11
<PAGE>

stated therein or necessary to make the statements therein not misleading, (ii)
any untrue statement or alleged untrue statement of a material fact contained in
any preliminary prospectus if used prior to the effective date of such
Registration Statement, or contained in the final prospectus (as amended or
supplemented, if the Company files any amendment thereof or supplement thereto
with the SEC) or the omission or alleged omission to state therein any material
fact necessary to make the statements made therein, in light of the
circumstances under which the statements therein were made, not misleading, or
(iii) any violation or alleged violation by the Company of the 1933 Act, the
1934 Act, any other law, including, without limitation, any state securities
law, or any rule or regulation thereunder relating to the offer or sale of the
Registrable Securities pursuant to a Registration Statement (the matters in the
foregoing clauses (i) through (iii) being, collectively, "Violations"). Subject
to Section 6(c), the Company shall reimburse the Indemnified Persons, promptly
as such expenses are incurred and are due and payable, for any reasonable legal
fees or other reasonable expenses incurred by them in connection with
investigating or defending any such Claim. Notwithstanding anything to the
contrary contained herein, the indemnification agreement contained in this
Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information furnished in writing to the Company by such Indemnified Person
for such Indemnified Person expressly for use in connection with the preparation
of the Registration Statement or any such amendment thereof or supplement
thereto, if such prospectus was timely made available by the Company pursuant to
Section 3(d); (ii) with respect to any preliminary prospectus, shall not inure
to the benefit of any such person from whom the person asserting any such Claim
purchased the Registrable Securities that are the subject thereof (or to the
benefit of any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary prospectus was corrected
in the prospectus, as then amended or supplemented, if such prospectus was
timely made available by the Company pursuant to Section 3(d), and the
Indemnified Person was promptly advised in writing not to use the incorrect
prospectus prior to the use giving rise to a violation and such Indemnified
Person, notwithstanding such advice, used it or failed to deliver the correct
prospectus as required by the 1933 Act and such correct prospectus was timely
made available pursuant to Section 3(d); (iii) shall not be available to the
extent such Claim is based on a failure of the Investor to deliver or to cause
to be delivered the prospectus made available by the Company, including a
corrected prospectus, if such prospectus or corrected prospectus was timely made
available by the Company pursuant to Section 3(d); and (iv) shall not apply to
amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of the Company, which consent shall not be
unreasonably withheld or delayed. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of the Indemnified
Person and shall survive the transfer of the Registrable Securities by the
Investors to permitted assignees under the Transaction Documents (as defined in
the Securities Purchase Agreement) pursuant to Section 9 hereof.

           b. In connection with any Registration Statement in which an Investor
is participating, each such Investor agrees to severally and not jointly
indemnify, hold harmless and defend, to the same extent and in the same manner
as is set forth in Section 6(a), the Company, each of its directors, each of its
officers who signs the Registration Statement and each Person, if any, who
controls the Company within the meaning of the 1933 Act or the 1934 Act (each,
an "Indemnified Party"), against any Claim or Indemnified Damages to which any
of

                                       12
<PAGE>

them may become subject, under the 1933 Act, the 1934 Act or otherwise,
insofar as such Claim or Indemnified Damages arise out of or are based upon any
Violation, in each case to the extent, and only to the extent, that such
Violation occurs in reliance upon and in conformity with written information
furnished to the Company by such Investor expressly for use in connection with
such Registration Statement; and, subject to Section 6(c), such Investor will
reimburse any legal or other expenses reasonably incurred by an Indemnified
Party in connection with investigating or defending any such Claim; provided,
however, that the indemnity agreement contained in this Section 6(b) and the
agreement with respect to contribution contained in Section 7 shall not apply to
amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of such Investor, which consent shall not be
unreasonably withheld or delayed; provided, further, however, that the Investor
shall be liable under this Section 6(b) for only that amount of a Claim or
Indemnified Damages as does not exceed the net proceeds to such Investor as a
result of the sale of Registrable Securities pursuant to such Registration
Statement. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of such Indemnified Party and shall
survive the transfer of the Registrable Securities by the Investors pursuant to
Section 9. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(b) with respect to any
preliminary prospectus shall not inure to the benefit of any Indemnified Party
if the untrue statement or omission of material fact contained in the
preliminary prospectus was corrected on a timely basis in the prospectus, as
then amended or supplemented.

           c. Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim,
such Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6,
deliver to the indemnifying party a written notice of the commencement thereof,
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses of not more than one counsel for such
Indemnified Person or Indemnified Party to be paid by the indemnifying party,
if, in the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party represented by such counsel in such proceeding. In the case of an
Indemnified Person, legal counsel referred to in the immediately preceding
sentence shall be selected by the Investors holding at least a majority in
interest of the Registrable Securities included in the Registration Statement to
which the Claim relates. The Indemnified Party or Indemnified Person shall
cooperate fully with the indemnifying party in connection with any negotiation
or defense of any such action or Claim by the indemnifying party and shall
furnish to the indemnifying party all information reasonably available to the
Indemnified Party or Indemnified Person which relates to such action or Claim.
The indemnifying party shall keep the Indemnified Party or Indemnified Person
fully apprised at all times as to the status of the defense or any settlement
negotiations with respect thereto. No indemnifying party shall be liable for any

                                       13
<PAGE>

settlement of any action, claim or proceeding effected without its prior written
consent, provided, however, that the indemnifying party shall not unreasonably
withhold, delay or condition its consent. No indemnifying party shall, without
the prior written consent of the Indemnified Party or Indemnified Person,
consent to entry of any judgment or enter into any settlement or other
compromise which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party or Indemnified Person of a
release from all liability in respect to such Claim or litigation. Following
indemnification as provided for hereunder, the indemnifying party shall be
subrogated to all rights of the Indemnified Party or Indemnified Person with
respect to all third parties or Persons relating to the matter for which
indemnification has been made. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the
Indemnified Person or Indemnified Party under this Section 6, except to the
extent that the indemnifying party is prejudiced in its ability to defend such
action.

           d. The indemnification required by this Section 6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

           e. The indemnity agreements contained herein shall be in addition to
(i) any cause of action or similar right of the Indemnified Party or Indemnified
Person against the indemnifying party or others, and (ii) any liabilities the
indemnifying party may be subject to pursuant to the law.

        7. Contribution.

        To the extent any indemnification by an indemnifying party is prohibited
or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no person involved in the sale of Registrable Securities which person is
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the 1933 Act) in connection with such sale shall be entitled to contribution
from any person involved in such sale of Registrable Securities who was not
guilty of fraudulent misrepresentation; and (ii) contribution by any seller of
Registrable Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities pursuant to
such Registration Statement.

        8. Reports Under The 1934 Act.

        With a view to making available to the Investors the benefits of Rule
144 promulgated under the 1933 Act or any other similar rule or regulation of
the SEC that may at any time permit the Investors to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to
use reasonable best efforts to:

           a. make and keep public information available, as those terms are
understood and defined in Rule 144;

                                       14
<PAGE>

           b. file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements (it being understood that
nothing herein shall limit the Company's obligations under Section 4(c) of the
Securities Purchase Agreement) and the filing of such reports and other
documents is required for the applicable provisions of Rule 144; and

           c. furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company, if
true, that it has complied with the reporting requirements of Rule 144, the 1933
Act and the 1934 Act, (ii) a copy of the most recent annual or quarterly report
of the Company and such other reports and documents so filed by the Company (if
such reports are not available on EDGAR), and (iii) such other information as
may be reasonably requested to permit the Investors to sell such securities
pursuant to Rule 144 without registration.

        9. Assignment of Registration Rights.

        The rights under this Agreement shall be automatically assignable by the
Investors to any transferee of all or any portion of such Investor's Registrable
Securities if: (i) the Investor agrees in writing with the transferee or
assignee to assign such rights, and a copy of such agreement is furnished to the
Company within a reasonable time after such assignment; (ii) the Company is,
within a reasonable time after such transfer or assignment, furnished with
written notice of (a) the name and address of such transferee or assignee, and
(b) the securities with respect to which such registration rights are being
transferred or assigned; (iii) immediately following such transfer or assignment
the further disposition of such securities by the transferee or assignee is
restricted under the 1933 Act and applicable state securities laws; (iv) the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein; and (v) such transfer shall have been made in
accordance with the applicable requirements of the Securities Purchase
Agreement.

        10. Amendment of Registration Rights.

        Provisions of this Agreement may be amended and the observance thereof
may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company
and Investors who then hold at least a majority of the Registrable Securities
then remaining unsold. Any amendment or waiver effected in accordance with this
Section 10 shall be binding upon each Investor and the Company. No such
amendment shall be effective to the extent that it applies to less than all of
the holders of the Registrable Securities. No consideration shall be offered or
paid to any Person to amend or consent to a waiver or modification of any
provision of any of this Agreement unless the same consideration also is offered
to all of the parties to this Agreement.

        11. Miscellaneous.

            a. A Person is deemed to be a holder of Registrable Securities
whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more Persons with

                                       15
<PAGE>

respect to the same Registrable Securities, the Company shall act upon the basis
of instructions, notice or election received from the such record owner of such
Registrable Securities.

            b. Any notices, consents, waivers or other communications required
or permitted to be given under the terms of this Agreement must be in writing
and will be deemed to have been delivered: (i) upon receipt, when delivered
personally; (ii) upon receipt, when sent by facsimile (provided confirmation of
transmission is mechanically or electronically generated and kept on file by the
sending party); or (iii) one Business Day after deposit with a nationally
recognized overnight delivery service, in each case properly addressed to the
party to receive the same. The addresses and facsimile numbers for such

and interpretation of this Agreement shall be governed by the internal laws of
the State of New York, without giving effect to any choice of law or conflict of
law provision or rule (whether of the State of New York or any other

AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE

            e. This Agreement, the Securities Purchase Agreement, the Warrants,
the Pledge and Security Agreement and the Convertible Debentures constitute the

Investors pursuant to this Agreement shall be made, unless otherwise specified
in this Agreement, by Investors holding at least a majority of the Registrable

Registrable Securities without regard to any limitations on conversion of the
Convertible Debentures or on exercises of the Warrants.

            k. The language used in this Agreement will be deemed to be the

                         FORM OF NOTICE OF EFFECTIVENESS
                            OF REGISTRATION STATEMENT

[Transfer Agent]
Attn:

        Re:    SONICblue Incorporated

Ladies and Gentlemen:

               We are counsel to SONICblue Incorporated, a Delaware corporation
(the "Company"), and have represented the Company in connection with that
certain Securities Purchase Agreement (the "Purchase Agreement") entered into by
and among the Company and the buyers named therein (collectively, the "Holders")
pursuant to which the Company issued to the Holders its 7 3/4% Secured Senior
Subordinated Convertible Debentures due 2005 (the "Convertible Debentures")
convertible into shares of the Company's Common Stock, par value $0.0001 per
share (the "Common Stock") and warrants exercisable for shares of its Common
Stock (the "Warrants"). Pursuant to the Purchase Agreement, the Company also has
entered into a Registration Rights Agreement with the Holders (the "Registration
Rights Agreement") pursuant to which the Company agreed, among other things, to
register the Registrable Securities (as defined in the Registration Rights
Agreement), including the shares of Common Stock issuable upon conversion of the
Convertible Debentures and exercise of the Warrants under the Securities Act of
1933, as amended (the "1933 Act"). In connection with the Company's obligations
under the Registration Rights Agreement, on ____________ ___, 200_, the Company
filed a Registration Statement on Form S-3 (File No. 333-_____________) (the
"Registration Statement") with the Securities and Exchange Commission (the
"SEC") relating to the Registrable Securities which names each of the Holders as
a selling stockholder thereunder.

               In connection with the foregoing, we advise you that a member of
the SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that as of [time] on
[date] any stop order suspending its effectiveness has been issued or that any
proceedings for that purpose are pending before, or threatened by, the SEC and
the Registrable Securities are available for resale under the 1933 Act pursuant
to the Registration Statement.

                                                   Very truly yours,

                                                   [ISSUER'S COUNSEL]

                                                   By:_____________________

shall be evidenced by the Revolving Credit Notes, substantially in the form

      2.2. Procedure for Borrowing Advances.

            (a) Borrowing Agent on behalf of any Borrower may notify Agent prior
to 11:00 a.m. on a Business Day of a Borrower's request to incur, on that day, a
Revolving Advance hereunder. Unless requested pursuant to Section 2.2(b) below,
all Advances shall be Domestic Rate Loans. Should any amount required to be paid
as interest hereunder, or as fees or other charges under this Agreement or any
other related agreement with Agent or Lenders, or with respect to any other
Obligation, become due, same shall be deemed a request for a Revolving Advance
as of the date such payment is due, in the amount required to pay in full such
interest, fee, charge or Obligation under this Agreement or any other agreement
with Agent or Lenders, and such request shall be irrevocable. Notwithstanding
anything to the contrary contained herein, Revolving Advances deemed to be
requested pursuant to this Section 2.2(a) shall be made regardless of (i) the
existence or continuance of any Default or Event of Default; (ii) the fact that
the aggregate amount outstanding of all Revolving Advances after giving effect
to such deemed request shall exceed the Maximum Loan Amount or the Formula
Amount, or (iii) any other restrictions on the making of Revolving Advances
contained herein.

            (b) Notwithstanding the provisions of (a) above, in the event any
Borrower desires to obtain a Eurodollar Rate Loan, Borrowing Agent shall give
Agent at least three (3)

                                       18
<PAGE>

Business Days' prior written notice, specifying (i) the date of the proposed
borrowing (which shall be a Business Day), (ii) the type of borrowing and the
amount on the date of such Advance to be borrowed, which amount shall be in a
minimum amount of $1,000,000 and in integral multiples of $500,000 thereafter,
and (iii) the duration of the first Interest Period therefor. Interest Periods
for Eurodollar Rate Loans shall be for one, two, or three months; provided, if
an Interest Period would end on a day that is not a Business Day, it shall end
on the next succeeding Business Day unless such day falls in the next succeeding
calendar month in which case the Interest Period shall end on the next preceding
Business Day. No Eurodollar Rate Loan shall be made available to Borrowers
during the continuance of a Default or an Event of Default.

            (c) Each Interest Period of a Eurodollar Rate Loan shall commence on
the date such Eurodollar Rate Loan is made and shall end on such date as
Borrowing Agent may elect as set forth in subsection (b)(iii) above provided
that the exact length of each Interest Period shall be determined in accordance
with the practice of the interbank market for offshore Dollar deposits and no
Interest Period shall end after the last day of the Term. Borrowing Agent shall
elect the initial Interest Period applicable to a Eurodollar Rate Loan by its
notice of borrowing given to Agent pursuant to Section 2.2(b) or by its notice
of conversion given to Agent pursuant to Section 2.2(d), as the case may be.
Borrowing Agent shall elect the duration of each succeeding Interest Period by
giving irrevocable written notice to Agent of such duration not less than three
(3) Business Days prior to the last day of the then current Interest Period
applicable to such Eurodollar Rate Loan. If Agent does not receive timely notice
of the Interest Period elected by Borrowing Agent, Borrowers shall be deemed to
have elected to convert to a Domestic Rate Loan subject to Section 2.2(d)
hereinbelow.

            (d) Provided that no Event of Default shall have occurred and be
continuing, any Borrower may, on the last Business Day of the then current
Interest Period applicable to any outstanding Eurodollar Rate Loan, or on any
Business Day with respect to Domestic Rate Loans, convert any such loan into a
loan of another type in the same aggregate principal amount provided that any
conversion of a Eurodollar Rate Loan shall be made only on the last Business Day
of the then current Interest Period applicable to such Eurodollar Rate Loan. If
a Borrower desires to convert a loan, Borrowing Agent shall give Agent not less
than three (3) Business Days' prior written notice to convert from a Domestic
Rate Loan to a Eurodollar Rate Loan or one (1) Business Day's prior written
notice to convert from a Eurodollar Rate Loan to a Domestic Rate Loan,
specifying the date of such conversion, the loans to be converted and if the
conversion is from a Domestic Rate Loan to any other type of loan, the duration
of the first Interest Period therefor. After giving effect to each such
conversion, there shall not be outstanding more than five (5) Eurodollar Rate
Loans, in the aggregate.

            (e) At its option and upon three (3) Business Days' prior written
notice, any Borrower may prepay the Eurodollar Rate Loans in whole at any time
or in part from time to time, without premium or penalty, but with accrued
interest on the principal being prepaid to the date of such repayment. Such
Borrower shall specify the date of prepayment of Advances which are Eurodollar
Rate Loans and the amount of such prepayment. In the event that any prepayment
of a Eurodollar Rate Loan is required or permitted on a date other than the last
Business Day of the then current Interest Period with respect thereto, such
Borrower shall indemnify Agent and Lenders therefor in accordance with Section
2.2(f) hereof.

            (f) Each Borrower shall indemnify Agent and Lenders and hold Agent
and Lenders harmless from and against any and all losses or expenses that Agent
and Lenders may

                                       19
<PAGE>

sustain or incur as a consequence of any voluntary prepayment, any mandatory
prepayment of any Eurodollar Rate Loans resulting from Revolving Advances
exceeding the Formula Amount, voluntary conversion of or any default by any
Borrower in the payment of the principal of or interest on any Eurodollar Rate
Loan or failure by any Borrower to complete a borrowing of, a prepayment of or
conversion of or to a Eurodollar Rate Loan after notice thereof has been given,
including, but not limited to, any interest payable by Agent or Lenders to
lenders of funds obtained by it in order to make or maintain its Eurodollar Rate
Loans hereunder. A certificate as to any additional amounts payable pursuant to
the foregoing sentence submitted by Agent or any Lender to Borrowing Agent shall
be conclusive absent manifest error. Such certificate shall be delivered to
Borrowing Agent within sixty (60) days of any such loss.

            (g) Notwithstanding any other provision hereof, if any applicable
law, treaty, regulation or directive, or any change therein or in the
interpretation or application thereof, shall make it unlawful for any Lender
(for purposes of this subsection (g), the term "Lender" shall include any Lender
and the office or branch where any Lender or any corporation or bank controlling
such Lender makes or maintains any Eurodollar Rate Loans to make or maintain its
Eurodollar Rate Loans), the obligation of Lenders to make Eurodollar Rate Loans
hereunder, as the case may be, shall forthwith be cancelled and Borrowers shall,
if any affected Eurodollar Rate Loans are then outstanding, promptly upon
request from Agent, either pay all such affected Eurodollar Rate Loans or
convert such affected Eurodollar Rate Loans into loans of another type. If any
such payment or conversion of any Eurodollar Rate Loan is made on a day that is
not the last day of the Interest Period applicable to such Eurodollar Rate Loan,
Borrowers shall pay Agent, upon Agent's request, such amount or amounts as may
be necessary to compensate Lenders for any loss or expense sustained or incurred
by Lenders in respect of such Eurodollar Rate Loan as a result of such payment
or conversion, including (but not limited to) any interest or other amounts
payable by Lenders to lenders of funds obtained by Lenders in order to make or
maintain such Eurodollar Rate Loan. A certificate as to any additional amounts
payable pursuant to the foregoing sentence submitted by Lenders to Borrowing
Agent shall be conclusive absent manifest error. Such certificate shall be
delivered to Borrowing Agent within sixty (60) days of any such loss.

      2.3. Disbursement of Advance Proceeds. All Advances shall be disbursed
from whichever office or other place Agent may designate from time to time and,
together with any and all other Obligations of Borrowers to Agent or Lenders,
shall be charged to Borrowers' Account on Agent's books. During the Term,
Borrowers may use the Revolving Advances by borrowing, prepaying and
reborrowing, all in accordance with the terms and conditions hereof. The
proceeds of each Revolving Advance requested by Borrowers or deemed to have been
requested by Borrowers under Section 2.2(a) hereof shall, with respect to
requested Revolving Advances to the extent Lenders make such Revolving Advances,
be made available to the applicable Borrower on the day so requested by way of
credit to such Borrower's operating account at PNC, or such other bank as
Borrowing Agent may designate following notification to Agent, in immediately
available federal funds or other immediately available funds or, with respect to
Revolving Advances deemed to have been requested by any Borrower pursuant to the
second sentence of Section 2.2, be disbursed to Agent to be applied to the
outstanding Obligations giving rise to such deemed request.

      2.4. INTENTIONALLY OMITTED.

      2.5. Maximum Advances. The aggregate balance of Advances outstanding at
any time shall not exceed the lesser of (a) Maximum Loan Amount or (b) the
Formula Amount.

                                       20
<PAGE>

      2.6. Repayment of Advances.

            (a) The Revolving Advances and (except to the extent otherwise
required hereunder to be paid sooner) all other Obligations shall be due and
payable in full on the last day of the Term subject to earlier prepayment as
herein provided.

            (b) Each Borrower recognizes that the amounts evidenced by checks,
notes, drafts or any other items of payment relating to and/or proceeds of
Collateral may not be collectible by Agent on the date received. In
consideration of Agent's agreement to conditionally credit Borrowers' Account as
of the Business Day on which Agent receives those items of payment, each
Borrower agrees that, in computing the charges under this Agreement, all items
of payment shall be deemed applied by Agent on account of the Obligations one
(1) Business Day after the Business Day Agent receives such payments via wire
transfer or electronic depository check. Agent is not, however, required to
credit Borrowers' Account for the amount of any item of payment which is
unsatisfactory to Agent and Agent may charge Borrowers' Account for the amount
of any item of payment which is credited and thereafter returned to Agent
unpaid.

            (c) All payments of principal, interest and other amounts payable
hereunder, or under any of the Other Documents shall be made to Agent at the
Payment Office not later than 1:00 P.M. (New York Time) on the due date therefor
in lawful money of the United States of America in federal funds or other funds
immediately available to Agent. Agent shall have the right to effectuate payment
on any and all Obligations due and owing hereunder by charging Borrowers'
Account or by making Advances as provided in Section 2.2 hereof.

            (d) Borrowers shall pay principal, interest, and all other amounts
payable hereunder, or under any related agreement, without any deduction
whatsoever, including, but not limited to, any deduction for any setoff or
counterclaim.

      2.7. Repayment of Excess Advances. The aggregate balance of Advances
outstanding at any time in excess of the maximum amount of Advances permitted
hereunder shall be immediately due and payable without the necessity of any
demand, at the Payment Office, whether or not a Default or Event of Default has
occurred.

      2.8. Statement of Account. Agent shall maintain, in accordance with its
customary procedures, a loan account ("Borrowers' Account") in the name of
Borrowers in which shall be recorded the date and amount of each Advance made by
Agent and the date and amount of each payment in respect thereof; provided,
however, the failure by Agent to record the date and amount of any Advance shall
not adversely affect Agent or any Lender. Each month, Agent shall send to
Borrowing Agent a statement showing the accounting for the Advances made,
payments made or credited in respect thereof, and other transactions between
Agent and Borrowers, during such month. The monthly statements shall be deemed
correct and binding upon Borrowers in the absence of manifest error and shall
constitute an account stated between Lenders and Borrowers unless Agent receives
a written statement of Borrowers' specific exceptions thereto within thirty (30)
days after such statement is received by Borrowing Agent. The records of Agent
with respect to the loan account shall be conclusive evidence absent manifest
error of the amounts of Advances and other charges thereto and of payments
applicable thereto.

      2.9. Letters of Credit. Subject to the terms and conditions hereof, Agent
shall issue or cause the issuance of Letters of Credit ("Letters of Credit") on
behalf of any Borrower; provided,

                                       21
<PAGE>

however, that Agent will not be required to issue or cause to be issued any
Letters of Credit to the extent that the face amount of such Letters of Credit
would then cause the sum of (i) the outstanding Revolving Advances plus (ii)
outstanding Letters of Credit to exceed the lesser of (x) the Maximum Loan
Amount or (y) the Formula Amount. The maximum amount of outstanding Letters of
Credit shall not exceed $4,000,000 in the aggregate at any time. All
disbursements or payments related to Letters of Credit shall be deemed to be
Domestic Rate Loans consisting of Revolving Advances and shall bear interest at
the Revolving Interest Rate for Domestic Rate Loans; Letters of Credit that have
not been drawn upon shall not bear interest.

      2.10. Issuance of Letters of Credit.

            (a) Borrowing Agent, on behalf of any Borrower or Subsidiary, may
request Agent to issue or cause the issuance of a Letter of Credit by delivering
to Agent at the Payment Office, Agent's form of Letter of Credit Application
(the "Letter of Credit Application") completed to the satisfaction of Agent;
and, such other certificates, documents and other papers and information as
Agent may reasonably request. Borrowing Agent, on behalf of any Borrower or
Subsidiary, also has the right to give instructions and make agreements with
respect to any application, any applicable letter of credit and security
agreement, any applicable letter of credit reimbursement agreement and/or any
other applicable agreement, any letter of credit and the disposition of
documents, disposition of any unutilized funds, and to agree with Agent upon any
amendment, extension or renewal of any Letter of Credit.

            (b) Each Letter of Credit shall, among other things, (i) provide for
the payment of sight drafts or acceptances of usance drafts when presented for
honor thereunder in accordance with the terms thereof and when accompanied by
the documents described therein and (ii) have an expiry date not later than one
(1) year after such Letter of Credit's date of issuance and in no event later
than the last day of the Term. Each Letter of Credit shall be subject to the
Uniform Customs and Practice for Documentary Credits (1993 Revision),
International Chamber of Commerce Publication No. 500, and any amendments or
revision thereof adhered to by the Issuer and, to the extent not inconsistent
therewith, the laws of the Commonwealth of Pennsylvania .

            (c) Agent shall use its reasonable efforts to notify Lenders of the
request by Borrowing Agent for a Letter of Credit hereunder.

      2.11. Requirements For Issuance of Letters of Credit.

            (a) In connection with the issuance of any Letter of Credit,
Borrowers shall indemnify, save and hold Agent, each Lender and each Issuer
harmless from any loss, cost, expense or liability arising from a third party
claim, including, without limitation, payments made by Agent, any Lender or any
Issuer and expenses and reasonable attorneys' fees incurred by Agent, any Lender
or Issuer arising out of, or in connection with, any Letter of Credit to be
issued or created for any Borrower or Subsidiary. Borrowers shall be bound by
Agent's or any Issuer's regulations and good faith interpretations of any Letter
of Credit issued or created for Borrowers' Account, although this interpretation
may be different from its own; and, neither Agent, nor any Lender, nor any
Issuer nor any of their correspondents shall be liable for any error,
negligence, or mistakes, whether of omission or commission, in following
Borrowing Agent's or any Borrower's instructions or those contained in any
Letter of Credit, or of any modifications, amendments or supplements thereto or
in issuing or paying any Letter of Credit, except for Agent's, any Lender's, any
Issuer's or such correspondents' gross negligence or willful misconduct.

                                       22
<PAGE>

            (b) Borrowing Agent shall authorize and direct any Issuer to name
the applicable Borrower or Subsidiary as the "Applicant" or "Account Party" of
each Letter of Credit. If Agent is not the Issuer of any Letter of Credit,
Borrowing Agent shall authorize and direct the Issuer to deliver to Agent all
instruments, documents, and other writings and property received by the Issuer
pursuant to the Letter of Credit and to accept and rely upon Agent's
instructions and agreements with respect to all matters arising in connection
with the Letter of Credit.

            (c) In connection with all Letters of Credit issued or caused to be
issued by Agent under this Agreement, each Borrower hereby appoints Agent, or
its designee, as its attorney, with full power and authority to, after and
during the continuance of an Event of Default (i) sign and/or endorse such
Borrower's name upon any warehouse or other receipts, letter of credit
applications and acceptances; (ii) sign such Borrower's name on bills of lading;
(iii) clear Inventory through the United States of America Customs Department
("Customs") in the name of such Borrower or Agent or Agent's designee, and to
sign and deliver to Customs officials powers of attorney in the name of such
Borrower for such purpose; and (iv) complete in such Borrower's name or Agent's,
or in the name of Agent's designee, any order, sale or transaction, obtain the
necessary documents in connection therewith, and collect the proceeds thereof.
Neither Agent nor its attorneys will be liable for any acts or omissions nor for
any error of judgment or mistakes of fact or law, except for Agent's or its
attorney's gross negligence or willful misconduct. This power, being coupled
with an interest, is irrevocable as long as any Letters of Credit remain
outstanding.

            (d) Each Lender shall to the extent of the percentage amount equal
to the product of such Lender's Commitment Percentage times the aggregate amount
of all unreimbursed reimbursement obligations arising from disbursements made or
obligations incurred with respect to the Letters of Credit be deemed to have
irrevocably purchased an undivided participation in each such unreimbursed
reimbursement obligation. In the event that at the time a disbursement is made
the unpaid balance of Revolving Advances exceeds or would exceed, with the
making of such disbursement, the lesser of the Maximum Loan Amount or the
Formula Amount, and such disbursement is not reimbursed by Borrowers within two
(2) Business Days, Agent shall promptly notify each Lender and upon Agent's
demand each Lender shall pay to Agent such Lender's proportionate share of such
unreimbursed disbursement together with such Lender's proportionate share of
Agent's unreimbursed costs and expenses relating to such unreimbursed
disbursement. Upon receipt by Agent of a repayment from any Borrower of any
amount disbursed by Agent for which Agent had already been reimbursed by
Lenders, Agent shall deliver to each Lender that Lender's pro rata share of such
repayment. Each Lender's participation commitment shall continue until the last
to occur of any of the following events: (A) Agent ceases to be obligated to
issue or cause to be issued Letters of Credit hereunder; (B) no Letter of Credit
issued hereunder remains outstanding and uncancelled or (C) all Persons (other
than the applicable Borrower) have been fully reimbursed for all payments made
under or relating to Letters of Credit.

      2.12. Additional Payments. Any sums expended by Agent or any Lender due to
any Borrower's failure to perform or comply with its obligations under this
Agreement or any Other Document including, without limitation, any Borrower's
obligations under Sections 4.2, 4.4, 4.12, 4.13, 4.14 and 6.1 hereof, may be
charged to Borrowers' Account as a Revolving Advance and added to the
Obligations.

      2.13. Manner of Borrowing and Payment.

                                       23
<PAGE>

            (a) Each borrowing of Revolving Advances shall be advanced according
to the applicable Commitment Percentages of Lenders.

            (b) Each payment (including each prepayment) by Borrowers on account
of the principal of and interest on the Revolving Advances, shall be applied to
the Revolving Advances pro rata according to the applicable Commitment
Percentages of Lenders. Except as expressly provided herein, all payments
(including prepayments) to be made by any Borrower on account of principal,
interest and fees shall be made without set off or counterclaim and shall be
made to Agent on behalf of the Lenders to the Payment Office, in each case on or
prior to 1:00 P.M., New York time, in Dollars and in immediately available
funds.

            (c) (i) Notwithstanding anything to the contrary contained in
Sections 2.13(a) and (b) hereof, commencing with the first Business Day
following the Closing Date, each borrowing of Revolving Advances shall be
advanced by Agent and each payment by any Borrower on account of Revolving
Advances shall be applied first to those Revolving Advances advanced by Agent.
On or before 1:00 P.M., New York time, on each Settlement Date commencing with
the first Settlement Date following the Closing Date, Agent and Lenders shall
make certain payments as follows: (I) if the aggregate amount of new Revolving
Advances made by Agent during the preceding Week (if any) exceeds the aggregate
amount of repayments applied to outstanding Revolving Advances during such
preceding Week, then each Lender shall provide Agent with funds in an amount
equal to its applicable Commitment Percentage of the difference between (w) such
Revolving Advances and (x) such repayments and (II) if the aggregate amount of
repayments applied to outstanding Revolving Advances during such Week exceeds
the aggregate amount of new Revolving Advances made during such Week, then Agent
shall provide each Lender with funds in an amount equal to its applicable
Commitment Percentage of the difference between (y) such repayments and (z) such
Revolving Advances.

                  (ii) Each Lender shall be entitled to earn interest at the
applicable Revolving Interest Rate on outstanding Advances which it has funded.

                  (iii) Promptly following each Settlement Date, Agent shall
submit to each Lender a certificate with respect to payments received and
Advances made during the Week immediately preceding such Settlement Date. Such
certificate of Agent shall be conclusive in the absence of manifest error.

            (d) If any Lender or Participant (a "benefited Lender") shall at any
time receive any payment of all or part of its Advances, or interest thereon, or
receive any Collateral in respect thereof (whether voluntarily or involuntarily
or by set-off) in a greater proportion than any such payment to and Collateral
received by any other Lender, if any, in respect of such other Lender's
Advances, or interest thereon, and such greater proportionate payment or receipt
of Collateral is not expressly permitted hereunder, such benefited Lender shall
purchase for cash from the other Lenders a participation in such portion of each
such other Lender's Advances, or shall provide such other Lender with the
benefits of any such Collateral, or the proceeds thereof, as shall be necessary
to cause such benefited Lender to share the excess payment or benefits of such
Collateral or proceeds ratably with each of the other Lenders; provided,
however, that if all or any portion of such excess payment or benefits is
thereafter recovered from such benefited Lender, such purchase shall be
rescinded, and the purchase price and benefits returned, to the extent of such
recovery, but without interest. Each Lender so purchasing a portion of another
Lender's Advances may exercise all rights of payment (including, without
limitation, rights of set-off) with respect to such portion as

                                       24
<PAGE>

fully as if such Lender were the direct holder of such portion.

            (e) Unless Agent shall have been notified by telephone, confirmed in
writing, by any Lender that such Lender will not make the amount which would
constitute its applicable Commitment Percentage of the Advances available to
Agent, Agent may (but shall not be obligated to) assume that such Lender shall
make such amount available to Agent on the next Settlement Date and, in reliance
upon such assumption, make available to Borrowers a corresponding amount. Agent
will promptly notify Borrowers of its receipt of any such notice from a Lender.
If such amount is made available to Agent on a date after such next Settlement
Date, such Lender shall pay to Agent on demand an amount equal to the product of
(i) the daily average Federal Funds Rate (computed on the basis of a year of 360
days) during such period as quoted by Agent, times (ii) such amount, times (iii)
the number of days from and including such Settlement Date to the date on which
such amount becomes immediately available to Agent. A certificate of Agent
submitted to any Lender with respect to any amounts owing under this paragraph
(e) shall be conclusive, in the absence of manifest error. If such amount is not
in fact made available to Agent by such Lender within three (3) Business Days
after such Settlement Date, Agent shall be entitled to recover such an amount,
with interest thereon at the rate per annum then applicable to such Revolving
Advances hereunder, on demand from Borrowers; provided, however, that Agent's
right to such recovery shall not prejudice or otherwise adversely affect
Borrowers' rights (if any) against such Lender.

      2.14. Use of Proceeds. Borrowers shall apply the proceeds of Advances to
(i) repay existing indebtedness owed to Exiting Lender, (ii) to consummate the
Acquisition, (iii) pay fees and expenses relating to this transaction, and (iv)
to provide for their working capital needs.

      2.15. Defaulting Lender.

            (a) Notwithstanding anything to the contrary contained herein, in
the event any Lender (x) has refused (which refusal constitutes a breach by such
Lender of its obligations under this Agreement) to make available its portion of
any Advance or (y) notifies either Agent or Borrowing Agent that it does not
intend to make available its portion of any Advance (if the actual refusal would
constitute a breach by such Lender of its obligations under this Agreement)
(each, a "Lender Default"), all rights and obligations hereunder of such Lender
(a "Defaulting Lender") as to which a Lender Default is in effect and of the
other parties hereto shall be modified to the extent of the express provisions
of this Section 2.15 while such Lender Default remains in effect.

            (b) Advances shall be incurred pro rata from Lenders
("Non-Defaulting Lenders") which are not Defaulting Lenders based on their
respective Commitment Percentages, and no Commitment Percentage of any Lender or
any pro rata share of any Advances required to be advanced by any Lender shall
be increased as a result of such Lender Default. Amounts received in respect of
principal of any type of Advances shall be applied to reduce the applicable
Advances of each Lender pro rata based on the aggregate of the outstanding
Advances of that type of all Lenders at the time of such application; provided,
that, such amount shall not be applied to any Advances of a Defaulting Lender at
any time when, and to the extent that, the aggregate amount of Advances of any
Non-Defaulting Lender exceeds such Non-Defaulting Lender's Commitment Percentage
of all Advances then outstanding.

            (c) A Defaulting Lender shall not be entitled to give instructions
to Agent or to approve, disapprove, consent to or vote on any matters relating
to this Agreement and the Other Documents. All amendments, waivers and other
modifications of this Agreement and the Other

                                       25
<PAGE>

Documents may be made without regard to a Defaulting Lender and, for purposes of
the definition of "Required Lenders", a Defaulting Lender shall be deemed not to
be a Lender and not to have Advances outstanding.

            (d) Other than as expressly set forth in this Section 2.15, the
rights and obligations of a Defaulting Lender (including the obligation to
indemnify Agent) and the other parties hereto shall remain unchanged. Nothing in
this Section 2.15 shall be deemed to release any Defaulting Lender from its
obligations under this Agreement and the Other Documents, shall alter such
obligations, shall operate as a waiver of any default by such Defaulting Lender
hereunder, or shall prejudice any rights which any Borrower, Agent or any Lender
may have against any Defaulting Lender as a result of any default by such
Defaulting Lender hereunder.

            (e) In the event a Defaulting Lender retroactively cures to the
satisfaction of Agent the breach which caused a Lender to become a Defaulting
Lender, such Defaulting Lender shall no longer be a Defaulting Lender and shall
be treated as a Lender under this Agreement.

III. INTEREST AND FEES.

      3.1. Interest. Interest on Advances shall be payable in arrears on the
first day of each month with respect to Domestic Rate Loans and, with respect to
Eurodollar Rate Loans, at the end of each Interest Period. Interest charges
shall be computed on the actual principal amount of Advances (other than
outstanding Letters of Credit) outstanding during the month (the "Monthly
Advances") at a rate per annum equal to the applicable Revolving Interest Rate.
Whenever, subsequent to the date of this Agreement, the Alternate Base Rate is
increased or decreased, the applicable Revolving Interest Rate for Domestic Rate
Loans shall be similarly changed without notice or demand of any kind by an
amount equal to the amount of such change in the Alternate Base Rate during the
time such change or changes remain in effect. The Eurodollar Rate shall be
adjusted with respect to Eurodollar Rate Loans without notice or demand of any
kind on the effective date and to the extent of any change in the Reserve
Percentage as of such effective date. Upon and after the occurrence of an Event
of Default and during the continuation thereof, the Obligations shall bear
interest at the Revolving Interest Rate plus two hundred (200) basis points per
annum, as applicable ("Default Rate").

      3.2. Letter of Credit Fees.

            (a) Borrowers shall pay (x) to Agent, for the benefit of Lenders,
fees for each Letter of Credit for the period from and excluding the date of
issuance of same to and including the date of expiration or termination, equal
to the average daily face amount of each outstanding Letter of Credit multiplied
by the Eurodollar Applicable Margin per annum, such fees to be calculated on the
basis of a 360-day year for the actual number of days elapsed and to be payable
monthly in arrears on the first day of each month and on the last day of the
Term and (y) to the Issuer, any and all fees and expenses as agreed upon by the
Issuer and the Borrowing Agent in connection with any Letter of Credit,
including, without limitation, in connection with the opening, amendment or
renewal of any such Letter of Credit and any acceptances created thereunder and
shall reimburse Agent for any and all fees and expenses, if any, paid by Agent
to the Issuer (all of the foregoing fees, the "Letter of Credit Fees"). All such
charges shall be deemed earned in full on the date when the same are due and
payable hereunder and shall not be subject to rebate or proration upon the
termination of this Agreement for any reason. Any such charge in effect at the
time of a particular transaction shall be the charge for that transaction,
notwithstanding any subsequent change in the

                                       26
<PAGE>

Issuer's prevailing charges for that type of transaction. All Letter of Credit
Fees payable hereunder shall be deemed earned in full on the date when the same
are due and payable hereunder and shall not be subject to rebate or proration
upon the termination of this Agreement for any reason.

            (b) Upon the occurrence and during the continuance of an Event of
Default or upon the termination of this Agreement, upon demand, Borrowers will
cause cash to be deposited and maintained in an account with Agent, as cash
collateral, in an amount equal to 105% of the outstanding Letters of Credit, and
each Borrower hereby irrevocably authorizes Agent, in its discretion, on such
Borrower's behalf and in such Borrower's name, to open such an account and to
make and maintain deposits therein, or in an account opened by such Borrower, in
the amounts required to be made by such Borrower, out of the proceeds of
Receivables or other Collateral or out of any other funds of such Borrower
coming into any Lender's possession at any time. Agent will invest such cash
collateral (less applicable reserves) in such short-term money-market items as
to which Agent and such Borrower mutually agree and the net return on such
investments shall be credited to such account and constitute additional cash
collateral. No Borrower may withdraw amounts credited to any such account except
upon payment and performance in full of all Obligations and termination of this
Agreement.

      3.3. Fees.

            (a) Facility Fee. If, for any month during the Term, the average
daily unpaid balance of the Revolving Advances and the average daily outstanding
balance Letters of Credit for each day of such month does not equal the Maximum
Loan Amount, then Borrowers shall pay to Agent, for the ratable benefit of
Lenders, a fee at a rate equal to 0.375% per annum on the amount by which the
Maximum Loan Amount exceeds such average daily unpaid balance. Such fee shall be
payable to Agent in arrears on the last Business Day of each month.

            (b) Collateral Evaluation Fee. Borrowers shall pay Agent a
collateral evaluation fee equal to $3,500 per month commencing on the first day
of the month following the Closing Date and on the first day of each month
thereafter during the Term. The collateral evaluation fee shall be deemed earned
in full on the date when same is due and payable hereunder and shall not be
subject to rebate or proration upon termination of this Agreement for any
reason.

            (c) Closing Fee. Borrowers shall pay to Agent a $500,000
non-refundable closing fee on the Closing Date ("Closing Fee"), less amounts
previously paid by Borrowers to Agent.

            (d) Collateral Monitoring Fee. Borrowers shall pay to Agent on the
first day of each month following any month in which Agent performs any
collateral monitoring, a collateral monitoring fee in an amount equal to $750
per day for each person performing such examination or analysis, plus all costs
and disbursements actually incurred by Agent in the performance of such
examination or analysis.

      3.4. Computation of Interest and Fees. Interest and fees hereunder shall
be computed on the basis of a year of 360 days and for the actual number of days
elapsed. If any payment to be made hereunder becomes due and payable on a day
other than a Business Day, the due date thereof shall be extended to the next
succeeding Business Day and interest thereon shall be payable at the applicable
Revolving Interest Rate during such extension.

                                       27
<PAGE>

      3.5. Maximum Charges. In no event whatsoever shall interest and other
charges charged hereunder exceed the highest rate permissible under law. In the
event interest and other charges as computed hereunder would otherwise exceed
the highest rate permitted under law, such excess amount shall be first applied
to any unpaid principal balance owed by Borrowers, and if the then remaining
excess amount is greater than the previously unpaid principal balance, Lenders
shall promptly refund such excess amount to Borrowers and the provisions hereof
shall be deemed amended to provide for such permissible rate.

      3.6. Increased Costs. In the event that any applicable law, treaty or
governmental regulation, or any change therein or in the interpretation or
application thereof, or compliance by any Lender (for purposes of this Section
3.6, the term "Lender" shall include Agent or any Lender and any corporation or
bank controlling Agent or any Lender) and the office or branch where Agent or
any Lender (as so defined) makes or maintains any Eurodollar Rate Loans with any
request or directive (whether or not having the force of law) from any central
bank or other financial, monetary or other authority, shall:

            (a) subject Agent or any Lender to any tax of any kind whatsoever
with respect to this Agreement or any Other Document or change the basis of
taxation of payments to Agent or any Lender of principal, fees, interest or any
other amount payable hereunder or under any Other Documents (except for changes
in the rate of tax on the overall net income of Agent or any Lender);

            (b) impose, modify or hold applicable any reserve, special deposit,
assessment or similar requirement against assets held by, or deposits in or for
the account of, advances or loans by, or other credit extended by, any office of
Agent or any Lender, including (without limitation) pursuant to Regulation D of
the Board of Governors of the Federal Reserve System; or

            (c) impose on Agent or any Lender or the London interbank Eurodollar
market any other condition with respect to this Agreement or any Other Document;

and the result of any of the foregoing is to increase the cost to Agent or any
Lender of making, renewing or maintaining its Advances hereunder by an amount
that Agent or such Lender deems to be material or to reduce the amount of any
payment (whether of principal, interest or otherwise) in respect of any of the
Advances by an amount that Agent or such Lender deems to be material, then, in
any case Borrowers shall promptly pay Agent or such Lender, upon its demand,
such additional amount as will compensate Agent or such Lender for such
additional cost or such reduction, as the case may be, provided that the
foregoing shall not apply to increased costs which are reflected in the
Eurodollar Rate, as the case may be. Agent or such Lender shall certify the
amount of such additional cost or reduced amount to Borrowers, and such
certification shall be conclusive absent manifest error.

      3.7. Basis For Determining Eurodollar Interest Rate Inadequate or Unfair.
In the event that Agent or any Lender shall have determined that reasonable
means do not exist for ascertaining the Eurodollar Rate applicable pursuant to
Section 2.2 hereof for any Interest Period; then Agent shall give Borrowing
Agent prompt written, telephonic or telegraphic notice of such determination. If
such notice is given, (i) any such requested Eurodollar Rate Loan shall be made
as a Domestic Rate Loan, unless Borrowing Agent shall notify Agent no later than
10:00 a.m. (New York City time) two (2) Business Days prior to the date of such
proposed borrowing, that its request for such borrowing shall be cancelled or
made as an unaffected type of Eurodollar Rate Loan, (ii) any Domestic Rate Loan
or Eurodollar Rate Loan which was to have been converted to an affected type

                                       28
<PAGE>

of Eurodollar Rate Loan shall be continued as or converted into a Domestic Rate
Loan, or, if Borrowing Agent shall notify Agent, no later than 10:00 a.m. (New
York City time) two (2) Business Days prior to the proposed conversion, shall be
maintained as an unaffected type of Eurodollar Rate Loan, and (iii) any
outstanding affected Eurodollar Rate Loans shall be converted into a Domestic
Rate Loan, or, if Borrowing Agent shall notify Agent, no later than 10:00 a.m.
(New York City time) two (2) Business Days prior to the last Business Day of the
then current Interest Period applicable to such affected Eurodollar Rate Loan,
shall be converted into an unaffected type of Eurodollar Rate Loan, on the last
Business Day of the then current Interest Period for such affected Eurodollar
Rate Loans. Until such notice has been withdrawn, Lenders shall have no
obligation to make an affected type of Eurodollar Rate Loan or maintain
outstanding affected Eurodollar Rate Loans and no Borrower shall have the right
to convert a Domestic Rate Loan or an unaffected type of Eurodollar Rate Loan
into an affected type of Eurodollar Rate Loan.

      3.8 Capital Adequacy.

            (a) In the event that Agent or any Lender shall have determined that
any applicable law, rule, regulation or guideline regarding capital adequacy, or
any change therein, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by Agent or any
Lender (for purposes of this Section 3.8, the term "Lender" shall include Agent
or any Lender and any corporation or bank controlling Agent or any Lender) and
the office or branch where Agent or any Lender makes or maintains any Eurodollar
Rate Loans with any request or directive regarding capital adequacy (whether or
not having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on Agent's
or any Lender's capital as a consequence of its obligations hereunder to a level
below that which Agent or such Lender could have achieved but for such adoption,
change or compliance (taking into consideration Agent's and each Lender's
policies with respect to capital adequacy) by an amount deemed by Agent or any
Lender to be material, then, from time to time, Borrowers shall pay upon demand
to Agent or such Lender such additional amount or amounts as will compensate
Agent or such Lender for such reduction. In determining such amount or amounts,
Agent or such Lender may use any reasonable averaging or attribution methods.
The protection of this Section 3.8 shall be available to Agent and each Lender
regardless of any possible contention of invalidity or inapplicability with
respect to the applicable law, regulation or condition.

            (b) A certificate of Agent or such Lender setting forth such amount
or amounts as shall be necessary to compensate Agent or such Lender with respect
to Section 3.8(a) hereof when delivered to Borrowers shall be conclusive absent
manifest error. Such certificate shall be delivered to Borrowing Agent within
sixty (60) days of Agent or any Lender determining any such amount or amounts.

IV. COLLATERAL: GENERAL TERMS

      4.1. Security Interest in the Collateral. To secure the prompt payment and
performance to Agent and each Lender of the Obligations, each Borrower hereby
assigns, pledges and grants to Agent for its benefit and for the ratable benefit
of each Lender a continuing security interest in and to all of its Collateral,
whether now owned or existing or hereafter acquired or arising and wheresoever
located. Each Borrower shall mark its books and records as may be necessary or
appropriate to evidence, protect and perfect Agent's security interest and shall
cause its financial statements to reflect such security interest.

                                       29
<PAGE>

      4.2. Perfection of Security Interest. Each Borrower shall take all action
that may be necessary or desirable, or that Agent may request, so as at all
times to maintain the validity, perfection, enforceability and priority of
Agent's security interest in the Collateral or to enable Agent to protect,
exercise or enforce its rights hereunder and in the Collateral, including, but
not limited to, (i) immediately discharging all Liens other than Permitted
Encumbrances, (ii) at Agent's request and using reasonable best efforts to
obtain, landlords' or mortgagees' lien waivers, (iii) upon Agent's request,
delivering to Agent, endorsed or accompanied by such instruments of assignment
as Agent may specify, and stamping or marking, in such manner as Agent may
specify, any and all chattel paper, instruments, letters of credits and advices
thereof and documents evidencing or forming a part of the Collateral, (iv)
entering into warehousing, lockbox and other custodial arrangements satisfactory
to Agent, and (v) executing and delivering financing statements, instruments of
pledge, mortgages, notices and assignments, in each case in form and substance
satisfactory to Agent, relating to the creation, validity, perfection,
maintenance or continuation of Agent's security interest under the Uniform
Commercial Code or other applicable law. Agent is hereby authorized to file
financing statements signed by Agent instead of Borrower in accordance with
Section 9-402(2) of the UCC . All charges, expenses and fees Agent may incur in
doing any of the foregoing, and any local taxes relating thereto, shall be
charged to Borrowers' Account as a Revolving Advance of a Domestic Rate Loan and
added to the Obligations, or, at Agent's option, shall be paid to Agent for the
ratable benefit of Lenders immediately upon demand.

      4.3. Disposition of Collateral and Other Assets. Each Borrower will
safeguard and protect all Collateral for Agent's general account and make no
disposition thereof whether by sale, lease or otherwise except as permitted
pursuant to Section 7.1 and the disposition or transfer of obsolete and worn-out
Equipment in the ordinary course of such Borrower's business.

      4.4. Preservation of Collateral. Following the occurrence of a Default or
Event of Default, in addition to the rights and remedies set forth in Section
11.1 hereof, Agent: (a) may at any time take such steps as Agent deems necessary
to protect Agent's interest in and to preserve the Collateral, including the
hiring of such security guards or the placing of other security protection
measures as Agent may deem appropriate; (b) may employ and maintain at any of
any Borrower's premises a custodian who shall have full authority to do all acts
necessary to protect Agent's interests in the Collateral; (c) may lease
warehouse facilities to which Agent may move all or part of the Collateral; (d)
may use any Borrower's owned or leased lifts, hoists, trucks and other
facilities or equipment for handling or removing the Collateral; and (e) shall
have, and is hereby granted, a right of ingress and egress to the places where
the Collateral is located, and may proceed over and through any of Borrower's
owned or leased property. Each Borrower shall cooperate fully with all of
Agent's efforts to preserve the Collateral and will take such actions to
preserve the Collateral as Agent may direct. All of Agent's expenses of
preserving the Collateral, including any expenses relating to the bonding of a
custodian, shall be charged to Borrowers' Account as a Revolving Advance of a
Domestic Rate Loan and added to the Obligations.

      4.5. Ownership of Collateral. With respect to the Collateral, at the time
the Collateral becomes subject to Agent's security interest: (a) each Borrower
shall be the sole owner of and fully authorized and able to sell, transfer,
pledge and/or grant a first priority security interest in each and every item of
the its respective Collateral to Agent; and, except for Permitted Encumbrances
the Collateral shall be free and clear of all Liens and encumbrances whatsoever;
(b) each document and agreement executed by each Borrower or delivered to Agent
or any Lender in connection with this Agreement shall be true and correct in all
respects; (c) all signatures and endorsements of each

                                       30
<PAGE>

Borrower that appear on such documents and agreements shall be genuine and each
Borrower shall have full capacity to execute same; and (d) each Borrower's
Equipment and Inventory shall be located as set forth on Schedule 4.5 and shall
not be removed from such location(s) without the prior written consent of Agent
except with respect to the sale of Inventory in the ordinary course of business,
Equipment to the extent permitted in Section 4.3 hereof and goods considered to
be mobile goods under the UCC.

      4.6. Defense of Agent's and Lenders' Interests. Until (a) payment and
performance in full of all of the Obligations and (b) termination of this
Agreement, Agent's interests in the Collateral shall continue in full force and
effect. During such period no Borrower shall, without Agent's prior written
consent, pledge, sell (except Inventory in the ordinary course of business and
Equipment to the extent permitted in Section 4.3 hereof), assign, transfer,
create or suffer to exist a Lien upon or encumber or allow or suffer to be
encumbered in any way except for Permitted Encumbrances, any part of the
Collateral. Each Borrower shall defend Agent's interests in the Collateral
against any and all Persons whatsoever. At any time following the occurrence and
during the continuance of an Event of Default and demand by Agent for payment of
all Obligations, Agent shall have the right to take possession of the indicia of
the Collateral and the Collateral in whatever physical form contained, including
without limitation: labels, stationery, documents, instruments and advertising
materials. If Agent exercises this right to take possession of the Collateral,
Borrowers shall, upon demand, assemble it in the best manner possible and make
it available to Agent at a place reasonably convenient to Agent. In addition,
with respect to all Collateral, Agent and Lenders shall be entitled to all of
the rights and remedies set forth herein and further provided by the Uniform
Commercial Code or other applicable law. Each Borrower shall, and Agent may, at
its option, instruct all suppliers, carriers, forwarders, warehousers or others
receiving or holding cash, checks, Inventory, documents or instruments in which
Agent holds a security interest to deliver same to Agent and/or subject to
Agent's order and if they shall come into any Borrower's possession, they, and
each of them, shall be held by such Borrower in trust as Agent's trustee, and
such Borrower will immediately deliver them to Agent in their original form
together with any necessary endorsement.

      4.7. Books and Records. Each Borrower shall (a) keep proper books of
record and account in which full, true and correct entries will be made of all
dealings or transactions of or in relation to its business and affairs; (b) set
up on its books accruals with respect to all taxes, assessments, charges, levies
and claims; and (c) on a reasonably current basis set up on its books, from its
earnings, allowances against doubtful Receivables, advances and investments and
all other proper accruals (including without limitation by reason of
enumeration, accruals for premiums, if any, due on required payments and
accruals for depreciation, obsolescence, or amortization of properties), which
should be set aside from such earnings in connection with its business. All
determinations pursuant to this subsection shall be made in accordance with, or
as required by, GAAP consistently applied in the opinion of such independent
public accountant as shall then be regularly engaged by Borrowers.

      4.8. Financial Disclosure. Each Borrower hereby irrevocably authorizes and
directs all accountants and auditors employed by such Borrower at any time
during the Term to exhibit and deliver to Agent and each Lender copies of any of
any Borrower's financial statements, trial balances or other accounting records
of any sort in the accountant's or auditor's possession, and to disclose to
Agent and each Lender any information such accountants may have concerning such
Borrower's financial status and business operations. Each Borrower hereby
authorizes all federal, state and municipal authorities to furnish to Agent and
each Lender copies of reports or examinations relating

                                       31
<PAGE>

to such Borrower, whether made by such Borrower or otherwise; however, Agent and
each Lender will attempt to obtain such information or materials directly from
such Borrower prior to obtaining such information or materials from such
accountants or such authorities. Prior to the occurrence of an Event of Default
or Default, Agent shall give Borrowers prior notice of its intention to seek
information under this Section 4.8.

      4.9. Compliance with Laws. Each Borrower shall comply with all acts,
rules, regulations and orders of any legislative, administrative or judicial
body or official applicable to its respective Collateral or any part thereof or
to the operation of such Borrower's business the non-compliance with which could
reasonably be expected to have a Material Adverse Effect on such Borrower. The
Collateral at all times shall be maintained in accordance with the requirements
of all insurance carriers which provide insurance with respect to the Collateral
so that such insurance shall remain in full force and effect.

      4.10. Inspection of Premises. At all reasonable times (and prior to the
occurrence of an Event of Default, with reasonable prior notice to Borrowing
Agent) Agent and each Lender shall have full access to and the right to audit,
check, inspect and make abstracts and copies from each Borrower's books,
records, audits, correspondence and all other papers relating to the Collateral
and the operation of each Borrower's business. Agent, any Lender and their
agents may enter upon any of each Borrower's premises at any time during
business hours and at any other reasonable time, and from time to time, for the
purpose of inspecting the Collateral and any and all records pertaining thereto
and the operation of such Borrower's business.

      4.11. Insurance. Each Borrower shall bear the full risk of any loss of any
nature whatsoever with respect to the Collateral. At each Borrower's own cost
and expense in amounts and with carriers acceptable to Agent, each Borrower
shall (a) keep all its insurable properties and properties in which each
Borrower has an interest insured against the hazards of fire, flood, sprinkler
leakage, those hazards covered by extended coverage insurance and such other
hazards, and for such amounts, as is customary in the case of companies engaged
in businesses similar to such Borrower's including, without limitation, business
interruption insurance; (b) maintain a bond in such amounts as is customary in
the case of companies engaged in businesses similar to such Borrower insuring
against larceny, embezzlement or other criminal misappropriation of insured's
officers and employees who may either singly or jointly with others at any time
have access to the assets or funds of such Borrower either directly or through
authority to draw upon such funds or to direct generally the disposition of such
assets; (c) maintain public and product liability insurance against claims for
personal injury, death or property damage suffered by others; (d) maintain all
such worker's compensation or similar insurance as may be required under the
laws of any state or jurisdiction in which such Borrower is engaged in business;
(e) maintain foreign credit insurance with an annual limit of not less than
$15,000,000 (on terms and with an insurance company acceptable to Agent in its
sole but reasonable discretion); and (f) furnish Agent with (i) copies of all
policies and evidence of the maintenance of such policies by the renewal thereof
at least thirty (30) days before any expiration date, and (ii) appropriate loss
payable endorsements in form and substance satisfactory to Agent, naming Agent
as a co-insured, additional insured and lender's loss payee as its interests may
appear with respect to all insurance coverage referred to in clauses (a) and (c)
above, and providing (A) that all proceeds thereunder shall be payable to Agent,
(B) no such insurance shall be affected by any act or neglect of the insured or
owner of the property described in such policy, and (C) that such policies and
co-insured, additional insured and lender's loss payee clauses may not be
cancelled, amended or terminated unless at least thirty (30) days' prior written
notice is given to Agent. In the event of any loss thereunder, the carriers
named therein hereby are directed by Agent and the

                                       32
<PAGE>

applicable Borrower to make payment for such loss to Agent and not to such
Borrower and Agent jointly. If any insurance losses are paid by check, draft or
other instrument payable to any Borrower and Agent jointly, Agent may endorse
such Borrower's name thereon and do such other things as Agent may deem
advisable to reduce the same to cash. Agent is hereby authorized to adjust and
compromise claims under insurance coverage referred to in clauses (a), (b) and
(e) above. All loss recoveries received by Agent upon any such insurance may be
applied to the Obligations, in such order as Agent in its sole discretion shall
determine. Any surplus shall be paid by Agent to Borrowers or applied as may be
otherwise required by law. Any deficiency thereon shall be paid by Borrowers to
Agent, on demand.

      4.12. Failure to Pay Insurance. If any Borrower fails to obtain insurance
as hereinabove provided, or to keep the same in force, Agent, if Agent so
elects, may obtain such insurance and pay the premium therefor on behalf of such
Borrower, and charge Borrowers' Account therefor as a Revolving Advance of a
Domestic Rate Loan and such expenses so paid shall be part of the Obligations.

      4.13. Payment of Taxes. Each Borrower will pay, when due, all taxes,
assessments and other Charges lawfully levied or assessed upon such Borrower or
any of the Collateral including, without limitation, real and personal property
taxes, assessments and charges and all franchise, income, employment, social
security benefits, withholding, and sales taxes. If any tax by any governmental
authority is or may be imposed on or as a result of any transaction between any
Borrower and Agent or any Lender which Agent or any Lender may be required to
withhold or pay or if any taxes, assessments, or other Charges remain unpaid
after the date fixed for their payment, or if any claim shall be made which, in
Agent's or any Lender's opinion, may possibly create a valid Lien on the
Collateral, Agent may with five (5) days prior notice to Borrowers pay the
taxes, assessments or other Charges and each Borrower hereby indemnifies and
holds Agent and each Lender harmless in respect thereof. Agent will not pay any
taxes, assessments or Charges to the extent that any Borrower has contested or
disputed those taxes, assessments or Charges in good faith, by expeditious
protest, administrative or judicial appeal or similar proceeding provided that
any related tax lien is stayed and sufficient reserves are established to the
satisfaction of Agent to protect Agent's security interest in or Lien on the
Collateral. The amount of any payment by Agent under this Section 4.13 shall be
charged to Borrowers' Account as a Revolving Advance of a Domestic Rate Loan and
added to the Obligations and, until Borrowers shall furnish Agent with an
indemnity therefor (or supply Agent with evidence satisfactory to Agent that due
provision for the payment thereof has been made), Agent may hold without
interest any balance standing to Borrowers' credit and Agent shall retain its
security interest in any and all Collateral held by Agent.

      4.14. Payment of Leasehold Obligations. Each Borrower shall at all times
pay, when and as due, its rental obligations under all leases under which it is
a tenant, and shall otherwise comply, in all material respects, with all other
terms of such leases and keep them in full force and effect and, at Agent's
request will provide evidence of having done so.

      4.15. Receivables.

            (a) Nature of Receivables. Each of the Receivables shall be a bona
fide and valid account representing a bona fide indebtedness incurred by the
Customer therein named, for a fixed sum as set forth in the invoice relating
thereto (provided immaterial or unintentional invoice errors shall not be deemed
to be a breach hereof) with respect to an absolute sale or lease and delivery of
goods upon stated terms of a Borrower, or work, labor or services theretofore
rendered

                                       33
<PAGE>

(except with respect to Domestic Non-Product Receivables) by a Borrower as of
the date each Receivable is created. Same shall be due and owing in accordance
with the applicable Borrower's standard terms of sale without dispute, setoff or
counterclaim except as may be stated on the accounts receivable schedules
delivered by Borrowers to Agent. At Agent's direction following either the
occurrence and continuance of an Event of Default hereunder or upon Agent's
receipt of a notice from Intergraph pursuant to the Standstill Agreement, all
invoices for any Maintenance Receivables shall be solely for Maintenance
Receivables and no other Receivables not constituting Maintenance Receivables
shall be included within such invoice.

            (b) Solvency of Customers. Each Customer, to the best of each
Borrower's knowledge, as of the date each Receivable is created, is and will be
solvent and able to pay all Receivables on which the Customer is obligated in
full when due or with respect to such Customers of any Borrower who are not
solvent such Borrower has set up on its books and in its financial records bad
debt reserves adequate to cover such Receivables.

            (c) Locations of Borrowers. Each Borrower's chief executive office
is located at the addresses set forth on Schedule 4.15(c) hereto. Until written
notice is given to Agent by Borrowing Agent of any other office at which any
Borrower keeps its records pertaining to Receivables, all such records shall be
kept at such executive office.

            (d) Collection of Receivables. Until any Borrower's or any
Subsidiary's authority to do so is terminated by Agent (which notice Agent may
give at any time following the occurrence of an Event of Default or a Default or
when Agent in its sole discretion deems it to be in Lenders' best interest to do
so), each Borrower will, or will cause a Subsidiary, at such Borrower's sole
cost and expense, but on Agent's behalf and for Agent's account, collect as
Agent's property and in trust for Agent all amounts received on Receivables, and
shall not commingle such collections with any Borrower's or Subsidiary's funds
(except with respect to a Subsidiary, at the direction of Agent)) or use the
same except to pay Obligations. Each Borrower shall, upon request, deliver, or
cause a Subsidiary to deliver, to Agent, or deposit in the Blocked Account, in
original form and on the date of receipt thereof, all checks, drafts, notes,
money orders, acceptances, cash and other evidences of Indebtedness.

            (e) Notification of Assignment of Receivables. At any time following
the occurrence of an Event of Default or Default, Agent shall have the right to
send notice of the assignment of, and Agent's security interest in, the
Receivables to any and all Customers or any third party holding or otherwise
concerned with any of the Collateral. Thereafter, Agent shall have the sole
right to collect the Receivables, take possession of the Collateral, or both.
Agent's actual collection expenses, including, but not limited to, stationery
and postage, telephone and telegraph, secretarial and clerical expenses and the
salaries of any collection personnel used for collection, may be charged to
Borrowers' Account and added to the Obligations.

            (f) Power of Agent to Act on Borrowers' Behalf. Agent shall have the
right (but no duty or obligation) to receive, endorse, assign and/or deliver in
the name of Agent or any Borrower, or any Subsidiary, any and all checks, drafts
and other instruments for the payment of money relating to the Receivables, and
each Borrower hereby waives notice of presentment, protest and non-payment of
any instrument so endorsed. Each Borrower hereby constitutes Agent or Agent's
designee as such Borrower's attorney and agent with power (i) to endorse such
Borrower's name upon any notes, acceptances, checks, drafts, money orders or
other evidences of payment or Collateral; (ii) following the occurrence and
during the continuance of an Event of Default, to sign

                                       34
<PAGE>

such Borrower's name on any invoice or bill of lading relating to any of the
Receivables, drafts against Customers, assignments and verifications of
Receivables; (iii) to send verifications of Receivables to any Customer; (iv) to
sign such Borrower's name on all financing statements or any other documents or
instruments deemed necessary or appropriate by Agent to preserve, protect, or
perfect Agent's interest in the Collateral and to file same; (v) following the
occurrence and during the continuance of an Event of Default to demand payment
of the Receivables; (vi) following the occurrence and during the continuance of
an Event of Default to enforce payment of the Receivables by legal proceedings
or otherwise; (vii) following the occurrence and during the continuance of an
Event of Default to exercise all of Borrowers' rights and remedies with respect
to the collection of the Receivables and any other Collateral; (viii) following
the occurrence and during the continuance of an Event of Default to settle,
adjust, compromise, extend or renew the Receivables; (ix) following the
occurrence and during the continuance of an Event of Default to settle, adjust
or compromise any legal proceedings brought to collect Receivables; (x)
following the occurrence and during the continuance of an Event of Default to
prepare, file and sign such Borrower's name on a proof of claim in bankruptcy or
similar document against any Customer; (xi) following the occurrence and during
the continuance of an Event of Default to prepare, file and sign such Borrower's
name on any notice of Lien, assignment or satisfaction of Lien or similar
document in connection with the Receivables; and (xii) following the occurrence
of an Event of Default or Default, to do all other acts and things necessary to
carry out this Agreement. All acts of said attorney and agent or designee are
hereby ratified and approved, and said attorney and agent or designee shall not
be liable for any acts of omission or commission nor for any error of judgment
or mistake of fact or of law, unless done maliciously or with gross (not mere)
negligence; this power being coupled with an interest is irrevocable while any
of the Obligations remain unpaid. Agent shall have the right at any time to
change the address for delivery of mail addressed to any Borrower to such
address as Agent may designate and to receive, open and dispose of all mail
addressed to any Borrower.

            (g) No Liability. Neither Agent nor any Lender shall, under any
circumstances or in any event whatsoever, have any liability for any error or
omission or delay of any kind occurring in the settlement, collection or payment
of any of the Receivables or any instrument received in payment thereof, or for
any damage resulting therefrom. Agent may, without notice or consent from any
Borrower following the occurrence and during the continuance of an Event of
Default or Default, sue upon or otherwise collect, extend the time of payment
of, compromise or settle for cash, credit or upon any terms any of the
Receivables or any other securities, instruments or insurance applicable thereto
and/or release any obligor thereof. Agent is authorized and empowered to accept
the return of the goods represented by any of the Receivables, without notice to
or consent by any Borrower, all without discharging or in any way affecting any
Borrower's liability hereunder.

            (h) Establishment of a Lockbox Account, Dominion Account. All
proceeds of Collateral shall, at the direction of Agent, be deposited by
Borrowers into a lockbox account, dominion account or such other "blocked
account" ("Blocked Accounts") as Agent may require pursuant to an arrangement
with such bank as may be selected by Borrowers and be acceptable to Agent. In
addition, all proceeds of Receivables generated by a Subsidiary of a Borrower
shall, at the direction of Agent, be deposited into a Blocked Account. All
proceeds of Receivables generated by a Subsidiary organized outside of the
United States shall be deposited in the Foreign Blocked Accounts. Amounts in the
excess of $25,000 and Subsidiaries' scheduled working capital requirements (as
delivered to Agent) in the Foreign Blocked Accounts shall be transferred weekly
(or more frequently if required by Agent) into any one or more accounts
designated by Agent.

                                       35
<PAGE>

Borrowers shall, or cause Subsidiaries of a Borrower to, issue to any such bank,
an irrevocable letter of instruction directing said bank to transfer such funds
so deposited to Agent, either to any account maintained by Agent at said bank or
by wire transfer to appropriate account(s) of Agent. All funds deposited in such
Blocked Account shall immediately become the property of Agent and Borrowers
shall, or cause Subsidiaries of a Borrower to, obtain the agreement by such bank
to waive any offset rights against the funds so deposited. Neither Agent nor any
Lender assumes any responsibility for such blocked account arrangement,
including without limitation, any claim of accord and satisfaction or release
with respect to deposits accepted by any bank thereunder. Alternatively, Agent
may establish depository accounts ("Depository Accounts") in the name of Agent
at a bank or banks for the deposit of such funds and Borrowers shall deposit all
proceeds of Collateral, or cause Subsidiaries of a Borrower to deposit all
proceeds of Receivables, or cause same to be deposited, in kind, in such
Depository Accounts of Agent in lieu of depositing same to the Blocked Accounts.

            (i) Adjustments. No Borrower will, without Agent's consent,
compromise or adjust any Receivables (or extend the time for payment thereof) or
accept any returns of merchandise or grant any additional discounts, allowances
or credits thereon except for those compromises, adjustments, returns,
discounts, credits and allowances as have been heretofore customary in the
business of such Borrower.

      4.16. Inventory. To the extent Inventory held for sale or lease has been
produced by any Borrower, it has been and will be produced by such Borrower, to
the extent applicable, in accordance with the Federal Fair Labor Standards Act
of 1938, as amended, and all rules, regulations and orders thereunder.

      4.17. Maintenance of Equipment. The Equipment shall be maintained in good
operating condition and repair (reasonable wear and tear excepted) and all
necessary replacements of and repairs thereto shall be made so that the value
and operating efficiency of the Equipment shall be maintained and preserved. No
Borrower shall use or operate the Equipment in violation of any law, statute,
ordinance, code, rule or regulation.

      4.18. Exculpation of Liability. Nothing herein contained shall be
construed to constitute Agent or any Lender as any Borrower's agent for any
purpose whatsoever (except to the extent necessary, and subject to the terms of
the preamble of this Article IV, for granting and the exercise of any powers of
attorney contained herein), nor shall Agent or any Lender be responsible or
liable for any shortage, discrepancy, damage, loss or destruction of any part of
the Collateral wherever the same may be located and regardless of the cause
thereof. Neither Agent nor any Lender, whether by anything herein or in any
assignment or otherwise, assume any of any Borrower's obligations under any
contract or agreement assigned to Agent or such Lender, and neither Agent nor
any Lender shall be responsible in any way for the performance by any Borrower
of any of the terms and conditions thereof.

      4.19. Environmental Matters.

            (a) Borrowers shall ensure that the Real Property remains in
material compliance with all Environmental Laws and they shall not place or
permit to be placed any Hazardous Substances on any Real Property except as
permitted by applicable law or appropriate governmental authorities.

            (b) Borrowers shall establish and maintain a system to assure and
monitor

                                       36
<PAGE>

continued compliance with all applicable Environmental Laws which system shall
include periodic reviews of such compliance.

            (c) Borrowers shall (i) employ in connection with the use of the
Real Property appropriate technology necessary to maintain compliance with any
applicable Environmental Laws and (ii) dispose of any and all Hazardous Waste
generated at the Real Property only at facilities and with carriers that
maintain valid permits under RCRA and any other applicable Environmental Laws.
Borrowers shall use commercially reasonable efforts to obtain certificates of
disposal, such as hazardous waste manifest receipts, from all treatment,
transport, storage or disposal facilities or operators employed by Borrowers in
connection with the transport or disposal of any Hazardous Waste generated at
the Real Property.

            (d) In the event any Borrower obtains, gives or receives notice of
any Release or threat of Release of a reportable quantity of any Hazardous
Substances at the Real Property (any such event being hereinafter referred to as
a "Hazardous Discharge") or receives any notice of violation, request for
information or notification that it is potentially responsible for investigation
or cleanup of environmental conditions at the Real Property, demand letter or
complaint, order, citation, or other written notice with regard to any Hazardous
Discharge or violation of Environmental Laws affecting the Real Property or any
Borrower's interest therein (any of the foregoing is referred to herein as an
"Environmental Complaint") from any Person, including any state agency
responsible in whole or in part for environmental matters in the state in which
the Real Property is located or the United States Environmental Protection
Agency (any such person or entity hereinafter the "Authority"), then Borrowing
Agent shall, within five (5) Business Days, give written notice of same to Agent
detailing facts and circumstances of which any Borrower is aware giving rise to
the Hazardous Discharge or Environmental Complaint. Such information is to be
provided to allow Agent to protect its security interest in the Real Property
and the Collateral and is not intended to create nor shall it create any
obligation upon Agent or any Lender with respect thereto.

            (e) Borrowers shall promptly forward to Agent copies of any request
for information, notification of potential liability, demand letter relating to
potential responsibility with respect to the investigation or cleanup of
Hazardous Substances at any other site owned, operated or used by any Borrower
to dispose of Hazardous Substances and shall continue to forward copies of
correspondence between any Borrower and the Authority regarding such claims to
Agent until the claim is settled. Borrowers shall promptly forward to Agent
copies of all documents and reports concerning a Hazardous Discharge at the Real
Property that any Borrower is required to file under any Environmental Laws.
Such information is to be provided solely to allow Agent to protect Agent's
security interest in the Real Property and the Collateral.

            (f) Borrowers shall respond promptly to any Hazardous Discharge or
Environmental Complaint and take all necessary action in order to safeguard the
health of any Person and to avoid subjecting the Collateral or Real Property to
any Lien. If any Borrower shall fail to respond promptly to any Hazardous
Discharge or Environmental Complaint or any Borrower shall fail to comply with
any of the requirements of any Environmental Laws, Agent on behalf of Lenders
may, but without the obligation to do so, for the sole purpose of protecting
Agent's interest in Collateral: (A) give such notices or (B) enter onto the Real
Property (or authorize third parties to enter onto the Real Property) and take
such actions as Agent (or such third parties as directed by Agent) deem
reasonably necessary or advisable, to clean up, remove, mitigate or otherwise
deal with any such Hazardous Discharge or Environmental Complaint. All
reasonable costs and expenses

                                       37
<PAGE>

incurred by Agent and Lenders (or such third parties) in the exercise of any
such rights, including any sums paid in connection with any judicial or
administrative investigation or proceedings, fines and penalties, together with
interest thereon from the date expended at the Default Rate for Domestic Rate
Loans constituting Revolving Advances shall be paid upon demand by Borrowers,
and until paid shall be added to and become a part of the Obligations secured by
the Liens created by the terms of this Agreement or any other agreement between
Agent, any Lender and any Borrower.

            (g) Promptly upon the written request of Agent from time to time,
Borrowers shall provide Agent, at Borrowers' expense, with an environmental site
assessment or environmental audit report prepared by an environmental
engineering firm acceptable in the reasonable opinion of Agent, to assess with a
reasonable degree of certainty the existence of a Hazardous Discharge and the
potential costs in connection with abatement, cleanup and removal of any
Hazardous Substances found on, under, at or within the Real Property. Any report
or investigation of such Hazardous Discharge proposed and acceptable to an
appropriate Authority that is charged to oversee the clean-up of such Hazardous
Discharge shall be acceptable to Agent. If such estimates, individually or in
the aggregate, exceed $100,000, Agent shall have the right to require Borrowers
to post a bond, letter of credit or other security reasonably satisfactory to
Agent to secure payment of these costs and expenses.

            (h) Borrowers shall defend and indemnify Agent and Lenders and hold
Agent, Lenders and their respective employees, agents, directors and officers
harmless from and against all loss, liability, damage and expense, claims,
costs, fines and penalties, including attorney's fees, suffered or incurred by
Agent or Lenders under or on account of any Environmental Laws and arising out
of or relating to Borrowers or any of the Real Property, including, without
limitation, the assertion of any Lien thereunder, with respect to any Hazardous
Discharge, the presence of any Hazardous Substances affecting the Real Property,
whether or not the same originates or emerges from the Real Property or any
contiguous real estate, including any loss of value of the Real Property as a
result of the foregoing except to the extent such loss, liability, damage and
expense is attributable to any Hazardous Discharge resulting from actions on the
part of Agent or any Lender. Borrowers' obligations under this Section 4.19
shall arise upon the discovery of the presence of any Hazardous Substances at
the Real Property, whether or not any federal, state, or local environmental
agency has taken or threatened any action in connection with the presence of any
Hazardous Substances. Borrowers' obligation and the indemnifications hereunder
shall survive the termination of this Agreement.

            (i) For purposes of Section 4.19 and 5.7, all references to Real
Property shall be deemed to include all of Borrowers' right, title and interest
in and to its owned and leased premises.

      4.20. Financing Statements. Except for the financing statements filed by
Agent and the financing statements described on Schedule 1.2, no financing
statement covering any of the Collateral or any proceeds thereof is on file in
any public office.

Regulation G of the Board of Governors of the Federal Reserve System as now and

this Agreement or in the Acquisition Agreement, or in any financial statement,

and all amendments thereto, waivers relating thereto and other side letters or

waived, except pursuant to a written agreement or instrument which has
heretofore been delivered to Agent.

without regard to fault on the part of either party.

      5.20. Conflicting Agreements. No provision of any mortgage, indenture,

performance of, the terms of this Agreement or the Other Documents.

      5.21. Application of Certain Laws and Regulations. No Borrower nor any
Affiliate of any Borrower is subject to any statute, rule or regulation which
regulates the incurrence of any Indebtedness, including without limitation,
statutes or regulations relative to common or interstate carriers or to the sale
of electricity, gas, steam, water, telephone, telegraph or other public utility
services.

      5.22. Business and Property of Borrowers. Upon and after the Closing Date,
Borrowers do not propose to engage in any business other than as conducted as of

rights and Consents necessary for the conduct of the business of such Borrower
as conducted on the Closing Date.

      5.23. Section 20 Subsidiaries. Borrowers do not intend to use and shall

purchase during the underwriting period, or for 30 days thereafter, Ineligible

      5.24. Foreign Subsidiary Income. All EBITDA (other than amounts necessary
to maintain minimum working capital requirements) generated by each Subsidiary
of a Borrower organized outside of the United States included within the
consolidated financial statements for Bentley has been properly repatriated to
Bentley and to the best of Borrowers' knowledge, does not result in adverse tax
consequences of implied dividends to Borrowers and there are no restrictions
under the laws of any country that could limit the ability of such Subsidiary to
deliver such amount to Bentley. To the best of Borrowers' knowledge, should any
adverse tax consequences result from such repatriation, such tax consequences
will be mitigated by related foreign tax credits.

XI. LENDERS' RIGHTS AND REMEDIES AFTER DEFAULT.

      11.1. Rights and Remedies. Upon the occurrence of (i) an Event of Default
pursuant to Section 10.7 all Obligations shall be immediately due and payable
and this Agreement and the obligation of Lenders to make Advances shall be
deemed terminated; and, (ii) any of the other

                                       58
<PAGE>

Events of Default and at any time thereafter (such default not having previously
been cured), Agent shall have the right to decrease the Receivables Advance Rate
and at the option of Required Lenders all Obligations shall be immediately due
and payable and Lenders shall have the right to terminate this Agreement and to
terminate the obligation of Lenders to make Advances and (iii) a filing of a
petition against any Borrower in any involuntary case under any state or federal
bankruptcy laws, the obligation of Lenders to make Advances hereunder shall be
terminated other than as may be required by an appropriate order of the
bankruptcy court having jurisdiction over any Borrower. Upon the occurrence of
any Event of Default, Agent shall have the right to exercise any and all other
rights and remedies provided for herein, under the Uniform Commercial Code and
at law or equity generally, including, without limitation, the right to
foreclose the security interests granted herein and to realize upon any
Collateral by any available judicial procedure and/or to take possession of and
sell any or all of the Collateral with or without judicial process. Agent may
enter any of any Borrower's premises or other premises without legal process and
without incurring liability to any Borrower therefor, and Agent may thereupon,
or at any time thereafter, in its discretion without notice or demand, take the
Collateral and remove the same to such place as Agent may deem advisable and
Agent may require Borrowers to make the Collateral available to Agent at a
convenient place. With or without having the Collateral at the time or place of
sale, Agent may sell the Collateral, or any part thereof, at public or private
sale, at any time or place, in one or more sales, at such price or prices, and
upon such terms, either for cash, credit or future delivery, as Agent may elect.
Except as to that part of the Collateral which is perishable or threatens to
decline speedily in value or is of a type customarily sold on a recognized
market, Agent shall give Borrowers reasonable notification of such sale or
sales, it being agreed that in all events written notice mailed to Borrowers at
least seven (7) days prior to such sale or sales is reasonable notification. At
any public sale Agent or any Lender may bid for and become the purchaser, and
Agent, any Lender or any other purchaser at any such sale thereafter shall hold
the Collateral sold absolutely free from any claim or right of whatsoever kind,
including any equity of redemption and such right and equity are hereby
expressly waived and released by each Borrower. In connection with the exercise
of the foregoing remedies, Agent is granted permission to use all of each
Borrower's trademarks, trade styles, trade names, patents, patent applications,
licenses, franchises and other proprietary rights which are used in connection
with (a) Inventory for the purpose of disposing of such Inventory and (b)
Equipment for the purpose of completing the manufacture of unfinished goods. 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
upon any of the Obligations and any fees payable under this Agreement; and,
third, to the principal of the Obligations. If any deficiency shall arise,
Borrowers shall remain liable to Agent and Lenders therefor.

      11.2. Agent's Discretion. Agent shall have the right in its sole
discretion to determine which rights, Liens, security interests or remedies
Agent may at any time pursue, relinquish, subordinate, or modify or to take any
other action with respect thereto and such determination will not in any way
modify or affect any of Agent's or Lenders' rights hereunder. Nothing contained
in this Agreement or the Other Documents shall be deemed to compel Agent to
accept a cure of any Event of Default.

      11.3. Setoff. In addition to any other rights which Agent or any Lender
may have under applicable law, upon the occurrence of an Event of Default
hereunder, Agent and such Lender shall have a right to apply any Borrower's
property held by Agent and such Lender to reduce the Obligations.

                                       59
<PAGE>

      11.4. Rights and Remedies not Exclusive. The enumeration of the foregoing
rights and remedies is not intended to be exhaustive and the exercise of any
right or remedy shall not preclude the exercise of any other right or remedies
provided for herein or otherwise provided by law, all of which shall be
cumulative and not alternative.

XII. WAIVERS AND JUDICIAL PROCEEDINGS.

      12.1. Waiver of Notice. Each Borrower hereby waives notice of non-payment
of any of the Receivables, demand, presentment, protest and notice thereof with
respect to any and all instruments, notice of acceptance hereof, notice of loans
or advances made, credit extended, Collateral received or delivered, or any
other action taken in reliance hereon, and all other demands and notices of any
description, except such as are expressly provided for herein.

      12.2. Delay. No delay or omission on Agent's or any Lender's part in
exercising any right, remedy or option shall operate as a waiver of such or any
other right, remedy or option or of any default.

      12.3. JURY WAIVER. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES
ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A)
ARISING UNDER THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT
EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH
OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM
WITH RESPECT TO THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT
EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO
OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER
SOUNDING IN CONTRACT OR TORT OR OTHERWISE AND EACH PARTY HEREBY CONSENTS THAT
ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT
TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL
COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE
CONSENTS OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

XIII. EFFECTIVE DATE AND TERMINATION.

      13.1. Term. This Agreement, which shall inure to the benefit of and shall
be binding upon the respective successors and permitted assigns of each
Borrower, Agent and each Lender, shall become effective on the date hereof and
shall continue in full force and effect until December 31, 2003 (the "Initial
Term") or sooner terminated as herein provided. Agent and Lenders may, at their
sole and absolute option, elect to renew and extend this Agreement for
additional one (1) year periods (each a "Renewal Term") upon such terms and
conditions acceptable to Agent, Lenders and Borrowers. Agent and Lenders shall
endeavor to provide notice to Borrowing Agent prior to December 31, 2002 (and at
each time in the future at which time there are two (2) years remaining under
the Terms of this Agreement, if any), of its intention to either renew or not
renew this Agreement beyond the Initial Term or then applicable Renewal Term (if
any), but failure to provide such notice shall not result in any liability on
the part of Agent and/or any Lender or result in any extension of this
Agreement. Borrowers may terminate this Agreement at any time upon ninety (90)

                                       60
<PAGE>

days' prior written notice upon payment in full of the Obligations. In the event
the Obligations are prepaid and refinanced with another financial institution in
full prior to the last day of the Term (the date of such prepayment hereinafter
referred to as the "Early Termination Date"), Borrowers shall pay to Agent for
the benefit of Lenders an early termination fee in an amount equal to (x) 2.0%
of the Maximum Loan Amount if the Early Termination Date occurs on or after the
Closing Date to and including the date immediately preceding the first
anniversary of the Closing Date, (y) 1.0% of the Maximum Loan Amount if the
Early Termination Date occurs on or after the first anniversary of the Closing
Date to and including the date immediately preceding the second anniversary of
the Closing Date, and (z) 0.5% of the Maximum Loan Amount if the Early
Termination Date occurs on or after the second anniversary of the Closing Date
to and including the date immediately preceding the last day of the Term.

      13.2. Termination. The termination of the Agreement shall not affect any
Borrower's, Agent's or any Lender's rights, or any of the Obligations having
their inception prior to the effective date of such termination, and the
provisions hereof shall continue to be fully operative until all transactions
entered into, rights or interests created or Obligations have been fully
disposed of, concluded or liquidated. The security interests, Liens and rights
granted to Agent and Lenders hereunder and the financing statements filed
hereunder shall continue in full force and effect, notwithstanding the
termination of this Agreement or the fact that Borrowers' Account may from time
to time be temporarily in a zero or credit position, until all of the
Obligations (other than indemnity obligations hereunder that survive the
termination of this Agreement) of each Borrower have been paid or performed in
full after the termination of this Agreement or each Borrower has furnished
Agent and Lenders with an indemnification satisfactory to Agent and Lenders with
respect thereto. Accordingly, each Borrower waives any rights which it may have
under Section 9-404(1) of the Uniform Commercial Code to demand the filing of
termination statements with respect to the Collateral, and Agent shall not be
required to send such termination statements to each Borrower, or to file them
with any filing office, unless and until this Agreement shall have been
terminated in accordance with its terms and all Obligations paid in full in
immediately available funds. All representations, warranties, covenants, waivers
and agreements contained herein shall survive termination hereof until all
Obligations are paid or performed in full.

XIV. REGARDING AGENT.

      14.1. Appointment. Each Lender hereby designates PNC to act as Agent for
such Lender under this Agreement and the Other Documents. Each Lender hereby
irrevocably authorizes Agent to take such action on its behalf under the
provisions of this Agreement and the Other Documents and to exercise such powers
and to perform such duties hereunder and thereunder as are specifically
delegated to or required of Agent by the terms hereof and thereof and such other
powers as are reasonably incidental thereto and Agent shall hold all Collateral,
payments of principal and interest, fees charges and collections (without giving
effect to any collection days) received pursuant to this Agreement, for the
ratable benefit of Lenders. Agent may perform any of its duties hereunder by or
through its agents or employees. As to any matters not expressly provided for by
this Agreement (including without limitation, collection of the Note) Agent
shall not be required to exercise any discretion or take any action, but shall
be required to act or to refrain from acting (and shall be fully protected in so
acting or refraining from acting) upon the instructions of the Required Lenders,
and such instructions shall be binding; provided, however, that Agent shall not
be required to take any action which exposes Agent to liability or which is
contrary to this Agreement or the Other Documents or applicable law unless Agent
is furnished with an indemnification reasonably satisfactory to Agent with
respect thereto.

                                       61
<PAGE>

      14.2. Nature of Duties. Agent shall have no duties or responsibilities
except those expressly set forth in this Agreement and the Other Documents.
Neither Agent nor any of its officers, directors, employees or agents shall be
(i) liable for any action taken or omitted by them as such hereunder or in
connection herewith, unless caused by their gross (not mere) negligence or
willful misconduct, or (ii) responsible in any manner for any recitals,
statements, representations or warranties made by any Borrower or any officer
thereof contained in this Agreement, or in any of the Other Documents or in any
certificate, report, statement or other document referred to or provided for in,
or received by Agent under or in connection with, this Agreement or any of the
Other Documents or for the value, validity, effectiveness, genuineness, due
execution, enforceability or sufficiency of this Agreement, or any of the Other
Documents or for any failure of any Borrower to perform its obligations
hereunder. Agent shall not be under any obligation to any Lender to ascertain or
to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any of the Other Documents, or
to inspect the properties, books or records of any Borrower. The duties of Agent
as respects the Advances to Borrowers shall be mechanical and administrative in
nature; Agent shall not have by reason of this Agreement a fiduciary
relationship in respect of any Lender; and nothing in this Agreement, expressed
or implied, is intended to or shall be so construed as to impose upon Agent any
obligations in respect of this Agreement except as expressly set forth herein.

      14.3. Lack of Reliance on Agent and Resignation. Independently and without
reliance upon Agent or any other Lender, each Lender has made and shall continue
to make (i) its own independent investigation of the financial condition and
affairs of each Borrower in connection with the making and the continuance of
the Advances hereunder and the taking or not taking of any action in connection
herewith, and (ii) its own appraisal of the creditworthiness of each Borrower.
Agent shall have no duty or responsibility, either initially or on a continuing
basis, to provide any Lender with any credit or other information with respect
thereto, whether coming into its possession before making of the Advances or at
any time or times thereafter except as shall be provided by any Borrower
pursuant to the terms hereof. Agent shall not be responsible to any Lender for
any recitals, statements, information, representations or warranties herein or
in any agreement, document, certificate or a statement delivered in connection
with or for the execution, effectiveness, genuineness, validity, enforceability,
collectibility or sufficiency of this Agreement or any Other Document, or of the
financial condition of any Borrower, or be required to make any inquiry
concerning either the performance or observance of any of the terms, provisions
or conditions of this Agreement, the Note, the Other Documents or the financial
condition of any Borrower, or the existence of any Event of Default or any
Default.

      Agent may resign on sixty (60) days' written notice to each of Lenders and
Borrowing Agent and upon such resignation, the Required Lenders (and prior to
the occurrence and continuance of an Event of Default, with Borrowers' consent,
which consent will not be unreasonably withheld, delayed or conditioned), will
promptly designate a successor Agent reasonably satisfactory to Borrowers.

      Any such successor Agent shall succeed to the rights, powers and duties of
Agent, and the term "Agent" shall mean such successor agent effective upon its
appointment, and the former Agent's rights, powers and duties as Agent shall be
terminated, without any other or further act or deed on the part of such former
Agent. After any Agent's resignation as Agent, the provisions of this Article
XIV shall inure to its benefit as to any actions taken or omitted to be taken by
it while it was Agent under this Agreement.

                                       62
<PAGE>

      14.4. Certain Rights of Agent. If Agent shall request instructions from
Lenders with respect to any act or action (including failure to act) in
connection with this Agreement or any Other Document, Agent shall be entitled to
refrain from such act or taking such action unless and until Agent shall have
received instructions from the Required Lenders; and Agent shall not incur
liability to any Person by reason of so refraining. Without limiting the
foregoing, Lenders shall not have any right of action whatsoever against Agent
as a result of its acting or refraining from acting hereunder in accordance with
the instructions of the Required Lenders.

      14.5. Reliance. Agent shall be entitled to rely, and shall be fully
protected in relying, upon any note, writing, resolution, notice, statement,
certificate, telex, teletype or telecopier message, cablegram, order or other
document or telephone message believed by it to be genuine and correct and to
have been signed, sent or made by the proper person or entity, and, with respect
to all legal matters pertaining to this Agreement and the Other Documents and
its duties hereunder, upon advice of counsel selected by it. Agent may employ
agents and attorneys-in-fact and shall not be liable for the default or
misconduct of any such agents or attorneys-in-fact selected by Agent with
reasonable care.

      14.6. Notice of Default. Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder or under
the Other Documents, unless Agent has received notice from a Lender or a
Borrower referring to this Agreement or the Other Documents, describing such
Default or Event of Default and stating that such notice is a "notice of
default". In the event that Agent receives such a notice, Agent shall give
notice thereof to Lenders. Agent shall take such action with respect to such
Default or Event of Default as shall be reasonably directed by the Required
Lenders; provided, that, unless and until Agent shall have received such
directions, Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interests of Lenders.

      14.7. Indemnification. To the extent Agent is not reimbursed and
indemnified by Borrowers, each Lender will reimburse and indemnify Agent in
proportion to its respective portion of the Advances (or, if no Advances are
outstanding, according to its Commitment Percentage), from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by or asserted against Agent in performing its
duties hereunder, or in any way relating to or arising out of this Agreement or
any Other Document; provided that, Lenders shall not be liable for any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from Agent's gross
(not mere) negligence or willful misconduct.

      14.8. Agent in its Individual Capacity. With respect to the obligation of
Agent to lend under this Agreement, the Advances made by it shall have the same
rights and powers hereunder as any other Lender and as if it were not performing
the duties as Agent specified herein; and the term "Lender" or any similar term
shall, unless the context clearly otherwise indicates, include Agent in its
individual capacity as a Lender. Agent may engage in business with any Borrower
as if it were not performing the duties specified herein, and may accept fees
and other consideration from any Borrower for services in connection with this
Agreement or otherwise without having to account for the same to Lenders.

      14.9. Delivery of Documents. To the extent Agent receives financial
statements required

                                       63
<PAGE>

under Sections 9.6, 9.7, and 9.8 from any Borrower pursuant to the terms of this
Agreement, Agent will promptly furnish such documents and information to
Lenders.

      14.10. Borrowers' Undertaking to Agent. Without prejudice to their
respective obligations to Lenders under the other provisions of this Agreement,
each Borrower hereby undertakes with Agent to pay to Agent from time to time on
demand all amounts from time to time due and payable by it for the account of
Agent or Lenders or any of them pursuant to this Agreement to the extent not
already paid. Any payment made pursuant to any such demand shall pro tanto
satisfy the relevant Borrower's obligations to make payments for the account of
Lenders or the relevant one or more of them pursuant to this Agreement.

      14.11. Miscellaneous.

            (a) Agent shall administer this Agreement and the Other Documents
and service the Obligations with the same degree of care as Agent would use in
servicing a loan of similar size and type held for its own account.

            (b) Agent and Lenders have agreed that Agent shall administer the
Advances and maintain records in connection with Advances in accordance with
this Agreement and that the relationship between Agent and Lenders with respect
to Advances shall be only as provided in this Agreement.

            (c) Agent shall hold in its possession, at its offices at, or at
such other location as Agent shall designate in writing, the originals of this
Agreement and the Other Documents (except for the Notes), for the benefit of
itself and Lenders. Agent shall keep and maintain complete and accurate files
and records of all matters pertaining to the Advances. Upon reasonable prior
notice to Agent, the files and records shall be made available to any Lender and
its representatives and agents for inspection and copying during normal business
hours.

            (d) Except as otherwise expressly provided for in this Agreement,
Agent shall have the right, in its sole discretion, in each instance: (i)
receive, review and process all documents, certificates, opinions, insurance
policies, reports, requisitions and other materials of every nature and
description submitted by, or on behalf of, Borrowers or any other party, and
distribute same for review by Lenders; (ii) fund the Advances in accordance with
the provisions of this Agreement and the Other Documents; (iii) receive all
payments of principal, interest, fees and other charges paid by, or on behalf
of, Borrowers and distribute such funds to Lenders as specifically required in
this Agreement; (iv) enforce all of the rights, remedies and privileges afforded
or available to Lenders under the terms of this Agreement and the Other
Documents, any opinion, certificates, warranties, representations or insurance
policies furnished by or on behalf of Borrowers or any other party (but only
after election to declare an Event of Default or Default and/or to accelerate
the Obligations as provided in this Agreement); and (v) do or refrain from doing
all such other acts as may be reasonably necessary or incident to the
implementation, administration or servicing of the Advances and the enforcement
of the rights and remedies of Lenders.

            (e) In no event shall Agent be required to take any action which
exposes the directors, officers, agents or employees of Agent to personal
liability or which is contrary to this Agreement or the Other Documents or
applicable law. In acting hereunder as Agent (including, without limitation, the
taking and holding of the Collateral), Agent shall be acting for the account of
and as agent for all Lenders, to the extent of their respective pro rata shares
in the Advances.

                                       64
<PAGE>

            (f) In the event that all or any portion of the Collateral is
acquired by Agent as the result of a foreclosure or the acceptance of a deed or
assignment in lieu of foreclosure, or is retained in satisfaction of all or any
part of Borrowers' Obligations, title to any such Collateral or any portion
thereof shall be held in the name of Agent or a nominee or subsidiary of Agent
(which in any case is authorized to do business in the state in which such
Collateral is located), in any case as agent, for the ratable benefit of Agent
and Lenders. Agent shall manage, operate, repair, administer, complete,
construct, restore or otherwise deal with the Collateral acquired and administer
all transactions relating thereto in its reasonable business judgment,
including, without limitation, if Agent so determines, employing a management
agent and other agents, contractors and employees, including agents for the same
of such Collateral, and the collecting of rents and other sums from such
Collateral and paying the expense of such Collateral. Upon demand therefor by
Agent from time to time, each Lender will contribute its pro rata share of all
costs and expenses incurred by Agent in connection with the construction,
operation, management, maintenance, leasing and sale of such Collateral. In
addition, Agent shall render or cause to be rendered by Agent, to each Lender,
monthly, an income and expense statement for such Collateral, and each Lender
shall promptly contribute its pro rata share of any operating loss for such
Collateral, and such other expenses and operating reserves as Agent shall deem
reasonably necessary. Lenders acknowledge that if title to any Collateral is
obtained by Agent or its nominee, such Collateral will not be held as a
permanent investment but will be liquidated as soon as practicable. Agent shall
undertake to sell such Collateral, at such price and upon such terms and
conditions as the Required Lenders shall reasonably determine to be most
advantageous.

XV. BORROWING AGENCY.

      15.1. Borrowing Agency Provisions.

            (a) Each Borrower hereby irrevocably designates Borrowing Agent to
be its attorney and agent and in such capacity to borrow, sign and endorse
notes, and execute and deliver all instruments, documents, writings and further
assurances now or hereafter required hereunder, on behalf of such Borrower or
Borrowers, and hereby authorizes Agent to pay over or credit all loan proceeds
hereunder in accordance with the request of Borrowing Agent.

            (b) The handling of this credit facility as a co-borrowing facility
with a borrowing agent in the manner set forth in this Agreement is solely as an
accommodation to Borrowers and at their request. Neither Agent nor any Lender
shall incur liability to Borrowers as a result thereof. To induce Agent and
Lenders to do so and in consideration thereof, each Borrower hereby indemnifies
Agent and each Lender and holds Agent and each Lender harmless from and against
any and all liabilities, expenses, losses, damages and claims of damage or
injury asserted against Agent or any Lender by any Person arising from or
incurred by reason of the handling of the financing arrangements of Borrowers as
provided herein, reliance by Agent or any Lender on any request or instruction
from Borrowing Agent or any other action taken by Agent or any Lender with
respect to this Section 15.1 except due to willful misconduct or gross (not
mere) negligence by the indemnified party.

            (c) All Obligations of Borrowers shall be joint and several, and
each Borrower shall make payment upon the maturity of the Obligations by
acceleration or otherwise, and such obligation and liability on the part of each
Borrower shall in no way be affected by any extensions, renewals and forbearance
granted to Agent or any Lender to any Borrower, failure of Agent or any

                                       65
<PAGE>

Lender to give any Borrower notice of borrowing or any other notice, any failure
of Agent or any Lender to pursue or preserve its rights against any Borrower,
the release by Agent or any Lender of any Collateral now or thereafter acquired
from any Borrower, and such agreement by each Borrower to pay upon any notice
issued pursuant thereto is unconditional and unaffected by prior recourse by
Agent or any Lender to the other Borrowers or any Collateral for such Borrower's
Obligations or the lack thereof.

      15.2. Waiver of Subrogation. Each Borrower expressly waives any and all
rights of subrogation, reimbursement, indemnity, exoneration, contribution of
any other claim which such Borrower may now or hereafter have against the other
Borrowers or other Person directly or contingently liable for the Obligations
hereunder, or against or with respect to the other Borrowers' property
(including, without limitation, any property which is Collateral for the
Obligations), arising from the existence or performance of this Agreement, until
termination of this Agreement and repayment in full of the Obligations.

XVI. MISCELLANEOUS.

      16.1. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the Commonwealth of Pennsylvania. Any judicial
proceeding brought by or against any Borrower with respect to any of the
Obligations, this Agreement or any related agreement may be brought in any court
of competent jurisdiction in the Commonwealth of Pennsylvania, United States of
America, and, by execution and delivery of this Agreement, each Borrower accepts
for itself and in connection with its properties, generally and unconditionally,
the non-exclusive jurisdiction of the aforesaid courts, and irrevocably agrees
to be bound by any judgment rendered thereby in connection with this Agreement.
Each Borrower hereby waives personal service of any and all process upon it and
consents that all such service of process may be made by registered mail (return
receipt requested) directed to Borrowing Agent at its address set forth in
Section 16.6 and service so made shall be deemed completed five (5) days after
the same shall have been so deposited in the mails of the United States of
America, or, at the Agent's and/or any Lender's option, by service upon
Borrowing Agent which each Borrower irrevocably appoints as such Borrower's
Agent for the purpose of accepting service within the Commonwealth of
Pennsylvania. Nothing herein shall affect the right to serve process in any
manner permitted by law or shall limit the right of Agent or any Lender to bring
proceedings against any Borrower in the courts of any other jurisdiction. Each
Borrower waives any objection to jurisdiction and venue of any action instituted
hereunder and shall not assert any defense based on lack of jurisdiction or
venue or based upon forum non conveniens. Any judicial proceeding by any
Borrower against Agent or any Lender involving, directly or indirectly, any
matter or claim in any way arising out of, related to or connected with this
Agreement or any related agreement, shall be brought only in a federal or state
court located in the County of Philadelphia, Commonwealth of Pennsylvania .

      16.2. Entire Understanding. (a) This Agreement and the documents executed
concurrently herewith contain the entire understanding between each Borrower,
Agent and each Lender and supersedes all prior agreements and understandings, if
any, relating to the subject matter hereof. Any promises, representations,
warranties or guarantees not herein contained and hereinafter made shall have no
force and effect unless in writing, signed by each Borrower's, Agent's and each
Lender's respective officers. Neither this Agreement nor any portion or
provisions hereof may be changed, modified, amended, waived, supplemented,
discharged, cancelled or terminated orally or by any course of dealing, or in
any manner other than by an agreement in writing, signed by the party to be
charged. Each Borrower acknowledges that it has been advised by counsel in

                                       66
<PAGE>

connection with the execution of this Agreement and Other Documents and is not
relying upon oral representations or statements inconsistent with the terms and
provisions of this Agreement.

            (b) The Required Lenders, Agent with the consent in writing of the
Required Lenders, and Borrowers may, subject to the provisions of this Section
16.2 (b), from time to time enter into written supplemental agreements to this
Agreement or the Other Documents executed by Borrowers, for the purpose of
adding or deleting any provisions or otherwise changing, varying or waiving in
any manner the rights of Lenders, Agent or Borrowers thereunder or the
conditions, provisions or terms thereof of waiving any Event of Default
thereunder, but only to the extent specified in such written agreements;
provided, however, that no such supplemental agreement shall, without the
consent of all Lenders:

                  (i) increase the Commitment Percentage or maximum dollar
commitment of any Lender.

                  (ii) extend the maturity of any Note or the due date for any
amount payable hereunder, or decrease the rate of interest or reduce any fee
payable by Borrowers to Lenders pursuant to this Agreement.

                  (iii) alter the definition of the term Required Lenders or
alter, amend or modify this Section 16.2(b).

                  (iv) release any Collateral during any calendar year (other
than in accordance with the provisions of this Agreement) having an aggregate
value in excess of $1,000,000.

                  (v) change the rights and duties of Agent.

                  (vi) permit any Revolving Advance to be made if after giving
effect thereto the total of Revolving Advances outstanding hereunder would
exceed the Formula Amount for more than thirty (30) consecutive Business Days or
exceed 105% of the Formula Amount.

                  (vii) increase the Advance Rates above the Advance Rates in
effect on the Closing Date.

Any such supplemental agreement shall apply equally to each Lender and shall be
binding upon Borrowers, Lenders and Agent and all future holders of the
Obligations. In the case of any waiver, Borrowers, Agent and Lenders shall be
restored to their former positions and rights, and any Event of Default waived
shall be deemed to be cured and not continuing, but no waiver of a specific
Event of Default shall extend to any subsequent Event of Default (whether or not
the subsequent Event of Default is the same as the Event of Default which was
waived), or impair any right consequent thereon.

      In the event that Agent requests the consent of a Lender pursuant to this
Section 16.2 and such Lender shall not respond or reply to Agent in writing
within ten (10) Business Days of delivery of such request, such Lender shall be
deemed to have consented to matter that was the subject of the request. In the
event that Agent requests the consent of a Lender pursuant to this Section 16.2
and such consent is denied, then PNC may, at its option, require such Lender to
assign its interest in the Advances to PNC or to another Lender or to any other
Person designated by the Agent (the

                                       67
<PAGE>

"Designated Lender"), for a price equal to the then outstanding principal amount
thereof plus accrued and unpaid interest and fees due such Lender, which
interest and fees shall be paid when collected from Borrowers. In the event PNC
elects to require any Lender to assign its interest to PNC or to the Designated
Lender, PNC will so notify such Lender in writing within forty five (45) days
following such Lender's denial, and such Lender will assign its interest to PNC
or the Designated Lender no later than five (5) days following receipt of such
notice pursuant to a Commitment Transfer Supplement executed by such Lender, PNC
or the Designated Lender, as appropriate, and Agent.

      Notwithstanding the foregoing, Agent may at its discretion and without the
consent of the Required Lenders, voluntarily permit the outstanding Revolving
Advances at any time to exceed the Formula Amount by up to the lesser of 105% of
the Formula Amount or $1,000,000 for up to thirty (30) consecutive Business
Days. For purposes of the preceding sentence, the discretion granted to Agent
hereunder shall not preclude involuntary overadvances that may result from time
to time due to the fact that the Formula Amount was unintentionally exceeded for
any reason, including, but not limited to, Collateral previously deemed to be
"Eligible Receivables" becomes ineligible, collections of Receivables applied to
reduce outstanding Revolving Advances are thereafter returned for insufficient
funds or overadvances are made to protect or preserve the Collateral. In the
event Agent involuntarily permits the outstanding Revolving Advances to exceed
the Formula Amount by more than 10%, Agent shall decrease such excess in as
expeditious a manner as is practicable under the circumstances and not
inconsistent with the reason for such excess. Revolving Advances made after
Agent has determined the existence of involuntary overadvances shall be deemed
to be involuntary overadvances and shall be decreased in accordance with the
preceding sentence. Nothing herein shall be deemed to restrict the ability of
Revolving Advances to be deemed to be made pursuant to the second sentence of
Section 2.2.

      16.3. Successors and Assigns; Participations; New Lenders.

            (a) This Agreement shall be binding upon and inure to the benefit of
Borrowers, Agent, each Lender, all future holders of the Obligations and their
respective successors and assigns, except that no Borrower may assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of Agent and each Lender.

            (b) Each Borrower acknowledges that in the regular course of
commercial banking business one or more Lenders may at any time and from time to
time sell participating interests in the Advances to other financial
institutions (each such transferee or purchaser of a participating interest, a
"Transferee"); provided however (i) all amounts payable by Borrowers to each
Lender shall be determined as if such Lender had not granted such participation
and (ii) any agreement pursuant to which any Lender may grant a participation:
(A) shall provide that such Lender shall retain the sole right and
responsibility to enforce the obligations of Borrowers hereunder including
without the right to approve to any modification, amendment or waiver of any
provisions of this Agreement and (B) such participation may provide that such
Lender will not agree to any amendment, modification or waiver of this Agreement
without the consent of the Transferee if such amendment, modification or waiver
would reduce the principal of or rate of interest on the Obligations, increase
the amount of the Maximum Loan Amount, postpone the date fixed for any scheduled
payment of principal of or interest on the Obligations, or release any
Collateral hereunder. Each Transferee may exercise all rights of payment
(including without limitation rights of set-off) with respect to the portion of
such Advances held by it or other Obligations payable hereunder as fully as if
such Transferee were the direct holder thereof provided that Borrowers shall not
be

                                       68
<PAGE>

required to pay to any Transferee more than the amount which it would have been
required to pay to Lender which granted an interest in its Advances or other
Obligations payable hereunder to such Transferee had such Lender retained such
interest in the Advances hereunder or other Obligations payable hereunder and in
no event shall Borrowers be required to pay any such amount arising from the
same circumstances and with respect to the same Advances or other Obligations
payable hereunder to both such Lender and such Transferee. Each Borrower hereby
grants to any Transferee a continuing security interest in any deposits, moneys
or other property actually or constructively held by such Transferee as security
for the Transferee's interest in the Advances.

            (c) Any Lender may with the consent of Agent (and prior to the
occurrence of an Event of Default or Default, Borrowing Agent) which shall not
be unreasonably withheld or delayed sell, assign or transfer all or any part of
its rights under this Agreement and the Other Documents to one or more
additional banks or financial institutions and one or more additional banks or
financial institutions may commit to make Advances hereunder (each a "Purchasing
Lender"), in minimum amounts of not less than $5,000,000, pursuant to a
commitment transfer supplement, executed by a Purchasing Lender, the transferor
Lender, and Agent and delivered to Agent for recording. Upon such execution,
delivery, acceptance and recording, from and after the transfer effective date
determined pursuant to such commitment transfer supplement, (i) Purchasing
Lender thereunder shall be a party hereto and, to the extent provided in such
commitment transfer supplement, have the rights and obligations of a Lender
thereunder with a Commitment Percentage as set forth therein, and (ii) the
transferor Lender thereunder shall, to the extent provided in such commitment
transfer supplement, be released from its obligations under this Agreement, the
commitment transfer supplement creating a novation for that purpose. Such
commitment transfer supplement shall be deemed to amend this Agreement to the
extent, and only to the extent, necessary to reflect the addition of such
Purchasing Lender and the resulting adjustment of the Commitment Percentages
arising from the purchase by such Purchasing Lender of all or a portion of the
rights and obligations of such transferor Lender under this Agreement and the
Other Documents. Borrowers hereby consent to the addition of such Purchasing
Lender and the resulting adjustment of the Commitment Percentages arising from
the purchase by such Purchasing Lender of all or a portion of the rights and
obligations of such transferor Lender under this Agreement and the Other
Documents. Borrowers shall execute and deliver such further documents and do
such further acts and things in order to effectuate the foregoing.

            (d) Agent shall maintain at its address a copy of each commitment
transfer supplement delivered to it and a register (the "Register") for the
recordation of the names and addresses of the Advances owing to each Lender from
time to time. The entries in the Register shall be conclusive, in the absence of
manifest error, and Borrowers, Agent and Lenders may treat each Person whose
name is recorded in the Register as the owner of the Advance recorded therein
for the purposes of this Agreement. The Register shall be available for
inspection by Borrowers or any Lender at any reasonable time and from time to
time upon reasonable prior notice. Agent shall receive a fee in the amount of
$3,500 payable by the applicable Purchasing Lender upon the effective date of
each transfer or assignment to such Purchasing Lender.

            (e) Each Borrower authorizes each Lender to disclose to any
Transferee or Purchasing Lender and any prospective Transferee or Purchasing
Lender any and all financial information in such Lender's possession concerning
such Borrower which has been delivered to such Lender by or on behalf of such
Borrower pursuant to this Agreement or in connection with such Lender's credit
evaluation of such Borrower, subject to a confidentiality arrangement between
such Lender and prospective Transferee.

                                       69
<PAGE>

      16.4. Application of Payments. Agent shall have the continuing and
exclusive right to apply or reverse and re-apply any payment and any and all
proceeds of Collateral to any portion of the Obligations. To the extent that any
Borrower makes a payment or Agent or any Lender receives any payment or proceeds
of the Collateral for any Borrower's benefit, which are subsequently
invalidated, declared to be fraudulent or preferential, set aside or required to
be repaid to a trustee, debtor in possession, receiver, custodian or any other
party under any bankruptcy law, common law or equitable cause, then, to such
extent, the Obligations or part thereof intended to be satisfied shall be
revived and continue as if such payment or proceeds had not been received by
Agent or such Lender.

      16.5. Indemnity. Each Borrower shall indemnify Agent, each Lender and each
of their respective officers, directors, Affiliates, employees and agents from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind or
nature whatsoever (including, without limitation, fees and disbursements of
counsel) which may be imposed on, incurred by, or asserted against Agent or any
Lender in any litigation, proceeding or investigation instituted or conducted by
any governmental agency or instrumentality or any other Person with respect to
any aspect of, or any transaction contemplated by, or referred to in, or any
matter related to, this Agreement or the Other Documents, whether or not Agent
or any Lender is a party thereto, except to the extent that any of the foregoing
arises out of the willful misconduct of the party being indemnified.

      16.6. Notice. Any notice or request hereunder may be given to any Borrower
or to Agent or any Lender at their respective addresses set forth below or at
such other address as may hereafter be specified in a notice designated as a

postage prepaid, or (c) upon actual receipt thereof when sent by a recognized

      16.7. Survival. The obligations of Borrowers under Sections 3.9, 4.19(h),
14.7 and 16.5 shall survive termination of this Agreement and the Other
Documents and payment in full of the Obligations.

      16.8. Severability. If any part of this Agreement is contrary to,
prohibited by, or deemed invalid under applicable laws or regulations, such
provision shall be inapplicable and deemed omitted to the extent so contrary,
prohibited or invalid, but the remainder hereof shall not be invalidated thereby
and shall be given effect so far as possible.

      16.9. Expenses. All costs and expenses including, without limitation,
reasonable attorneys' fees (including the allocated costs of in-house counsel)
and disbursements incurred by Agent and Agent on behalf of Lenders and Lenders,

collection of any Collateral, or (b) in connection with the entering into,

         16.10. Injunctive Relief. Each Borrower recognizes that, in the event
any Borrower fails to

                                       71
<PAGE>

perform, observe or discharge any of its obligations or liabilities under this
Agreement, any remedy at law may prove to be inadequate relief to Lenders;
therefore, Agent, if Agent so requests, shall be entitled to temporary and
permanent injunctive relief in any such case without the necessity of proving
that actual damages are not an adequate remedy.

      16.11. Consequential Damages. Neither Agent nor any Lender, nor any agent
or attorney for any of them, shall be liable to any Borrower for consequential

each Transferee shall hold all non-public information obtained by Agent, such
Lender or such Transferee pursuant to the requirements of this Agreement in
accordance with Agent's, such Lender's and such Transferee's customary and
reasonable procedures for handling confidential information who need to know
such information in connection with this Agreement of this nature; provided,
