                           5.00% CONVERTIBLE DEBENTURE
                                DUE JULY 26, 2001

         THIS DEBENTURE is one of a series of duly authorized and issued
debentures of ELTRAX SYSTEMS, INC., a Minnesota corporation, having a principal
place of business at 400 Galleria Parkway, Suite 300, Atlanta, Georgia 30339
(the "Company"), designated as its 5.00% Convertible Debentures, due July 26,
2001, in the aggregate principal amount of Seven Million Dollars ($7,000,000)
(the "Debentures").

         FOR VALUE RECEIVED, the Company promises to pay to the order of Bay
Harbor Investments, Inc., or its registered assigns (the "Holder"), the
principal sum of Two Million Dollars ($2,000,000), on July 26, 2001 or such
earlier date as the Debentures are required or permitted to be repaid as
provided hereunder (the "Maturity Date") and to pay interest thereon at the rate
of 5.00% per annum, payable in arrears on each Conversion Date (as defined
herein) and on each March 31, June 30, September 30 and December 31 of each year
during which this Debenture remains outstanding (for purposes of payment of
interest, each Conversion Date and each quarterly date being an "Interest
Payment Date"), in cash. Interest shall be calculated on the basis of a 360-day
year of twelve thirty-day months and shall accrue daily (but compound annually)
commencing on the Original Issue Date (as defined in Section 7) until payment
(whether through conversion of all outstanding principal amount hereunder or
otherwise) in full of the principal sum, together with all accrued and unpaid
interest and other amounts which may become due hereunder, has been made.
Interest hereunder will be paid to the Person (as defined in Section 7) in whose
name this Debenture is registered on the records of the Company regarding
registration and transfers of Debentures (the "Debenture Register"). All overdue
accrued and unpaid interest to be paid in cash hereunder shall entail a late fee
at the rate of 18% per annum (or such lower maximum amount of interest permitted
to be

<PAGE>   2

charged under applicable law) (to accrue daily, from the date such interest is
due hereunder through and including the date of payment), payable in cash.

         This Debenture is subject to the following additional provisions:

         Section 1. This Debenture is exchangeable for an equal aggregate
principal amount of Debentures of different authorized denominations, as
requested by the Holder surrendering the same. No service charge will be made
for such registration of transfer or exchange.

         Section 2. This Debenture has been issued subject to certain investment
representations of the original Holder set forth in the Purchase Agreement (as
defined in Section 7) and may be transferred or exchanged to another Person only
in compliance with the Purchase Agreement. Prior to due presentment to the
Company for transfer of this Debenture, the Company and any agent of the Company
may treat the Person in whose name this Debenture is duly registered on the
Debenture Register as the owner hereof for the purpose of receiving payment as
herein provided and for all other purposes, whether or not this Debenture is
overdue, and neither the Company nor any such agent shall be affected by notice
to the contrary.

Payment Date or the Maturity Date, by acceleration or otherwise);

                     (ii)  the Company shall fail to observe or perform any
other covenant, agreement or warranty contained in, or otherwise commit any

Debenture (other than those matters that are the specific subject of another
Event of Default under this Section), and such failure or breach shall not have
been remedied within twenty Business Days after the date on which notice of such
failure or breach shall have been given;

                     (iii) the Company or any of its subsidiaries shall

which there may be issued, or by which there may be secured or evidenced any
indebtedness for borrowed money or money due under any long term leasing or
factoring arrangement of the Company in an amount exceeding five hundred
thousand dollars ($500,000), whether such indebtedness now exists or shall
hereafter be created and such default shall result in such indebtedness becoming

become due and payable without such indebtedness having been discharged in full
or any acceleration of such indebtedness having been rescinded or annulled in
full within the applicable grace period;

                     (v)    the Common Stock shall not be quoted for trading on

shall fail to be quoted or listed for trading on such Subsequent Market, for an
aggregate of five Trading Days;

                     (vi)   the Company shall be a party to any Change of

                     (vii)  an Underlying Shares Registration Statement shall
not have been declared effective by the Commission (as defined in Section 6) on

                     (viii) if, during the Effectiveness Period (as defined in

Holder shall not be permitted to resell

                                       3
<PAGE>   4

Registrable Securities (as defined in the Registration Rights Agreement) under
an Underlying Shares Registration Statement, in either case, for an aggregate of
more of than sixty Trading Days (which need not be consecutive Trading Days) in
any twelve month period;

                     (ix) an Event (as defined in the Registration Rights
Agreement) shall not have been cured to the reasonable satisfaction of the
Holder prior to the expiration of thirty days from the Event Date (as defined in
the Registration Rights Agreement) relating thereto (other than an Event
resulting from a failure of an Underlying Shares Registration Statement to be
declared effective by the Commission on or prior to the 175th day after the
Original Issue Date, which shall be covered by Section 3(a)(vii));

                     (x)  the Company shall fail for any reason to deliver
certificates to a Holder prior to the seventh (7th) Trading Day after a Delivery
Date (as defined in Section 4(e)) pursuant to and in accordance with Section
4(b) or the Company shall provide notice to the Holder, including by way of
public announcement, at any time, of its intention not to comply with requests
for conversions of any Debentures in accordance with the terms hereof; or

                     (xi) the Company shall fail for any reason to deliver the
payment in cash pursuant to a Buy-In (as defined herein) within five Business
Days after written notice for such Buy-In is provided.

                 (b) If any Event of Default occurs, the full principal amount
of this Debenture (and, at the Holder's option, all other Debentures then held
by such Holder), together with interest and other amounts owing in respect
thereof, to the date of acceleration shall become, at the Holder's election
immediately due and payable in cash. The aggregate amount payable upon an Event
of Default shall be equal to the sum of (i) the Mandatory Prepayment Amount (as
defined in Section 7) plus (ii) the product of (A) the number of Underlying
Shares issued in respect of conversions hereunder within thirty (30) days of the
date of a declaration of an Event of Default and then held by the Holder and (B)
the closing sales price of the Common Stock as reported by Bloomberg L.P. (or
the successor to its function of reporting share prices) on the date prepayment
is due or the date the full prepayment price is paid, whichever is greater.
Interest shall accrue on the prepayment amount hereunder from the seventh
Business Day after such amount is due (being the date of an Event of Default)
through the date of prepayment in full thereof at the rate of 18% per annum (or
such lesser maximum amount that is permitted to be paid by applicable law), to
accrue daily from the date such payment is due hereunder through and including
the date of payment. All Debentures and Underlying Shares for which the full
prepayment price hereunder shall have been paid in accordance herewith shall
promptly be surrendered to or as directed by the Company. The Holder need not
provide and the Company hereby waives any presentment, demand, protest or other
notice of any kind, and the Holder may immediately enforce any and all of its
rights and remedies hereunder and all other remedies available to it under
applicable law. Such declaration may be rescinded and annulled by Holder at any
time prior to payment hereunder. No such rescission or annulment shall affect
any subsequent Event of Default or impair any right consequent thereon.

       Section 4.    Conversion.

                 (a) Conversion at Option of Holder. The Holder shall effect
conversions hereunder by delivering to the Company by facsimile a completed
conversion notice in the form attached as Exhibit A (a "Holder Conversion
Notice") and delivery to the Company within two Trading Days thereafter of the
principal amount of Debentures to be converted. Each Holder Conversion Notice
shall specify the date on which such conversion is to be effected, which date
may not be prior to the date such Holder Conversion Notice is deemed to have
been delivered hereunder (a "Holder Conversion Date"). If no Holder Conversion
Date is specified in a Holder Conversion Notice, the Holder Conversion Date
shall be the date that such Holder Conversion Notice is deemed delivered
hereunder. Subject to Section 4(b), each Holder Conversion Notice, once given,
shall be irrevocable. If the Holder is converting less than all of the principal
amount represented by the Debenture(s) tendered by the Holder with the Holder
Conversion Notice, or if a conversion hereunder cannot be effected in full for
any reason, the Company shall honor such conversion to the extent permissible
hereunder and shall promptly deliver to such Holder (in the manner and within
the time set forth in Section 4(e)) a new Debenture for such principal amount as
has not been converted.

                 (b) Conversion at Option of the Company.

                     (i) If the conditions set forth in this subsection are
satisfied, the Company may require the conversion of all or a portion of the
principal amount of the Debentures subject to an effective Underlying Shares
Registration Statement. The Company shall only have the right to require
conversions hereunder if (i) the closing sales price of the Common Stock as
reported by Bloomberg L.P. (or any successor to its function of reporting share
prices) exceeds $6.72 (subject to equitable adjustment in the event of stock
splits and similar events) for twenty consecutive Trading Days following the
date on which an Underlying Shares Registration Statement shall have first been
declared effective by the Securities and Exchange Commission (the "Effective
Date"), (ii) the Underlying Shares Registration Statement shall be effective and
the prospectus thereunder available to the Holders for the resale of all
Underlying Shares issuable upon such conversion during the entire twenty Trading
Day period and on the Company Conversion Date (as defined below) or Underlying
Shares may be sold by the Holder subject to such conversion without volume
limitation under Rule 144(k) promulgated under the Securities Act on the Company
Conversion Date, (iii) the Company has available sufficient unreserved and
available shares of Common Stock to fulfill its share delivery requirements upon
such conversion, (iv) the Common Stock is listed or quoted for trading on the
NASDAQ or a Subsequent Market during the entire twenty Trading Day calculation
period described above in this subsection, (v) such conversion would not result
in a violation of Section 4d(i), (ii) or (iii), and (vi) the Company shall not
have been more than three Trading Days late in delivering any conversion shares
pursuant to Section 4(e).

                     (ii) The Company shall exercise its right to require
conversions under Section 4(b)(i) by delivering to the Holder a completed
conversion notice in the form attached as Exhibit B (a "Company Conversion
Notice"). Each of a Company Conversion Notice and a Holder Conversion Notice is
sometimes referred to herein as a "Conversion Notice". Each

                                       5

<PAGE>   6

Company Conversion Notice shall specify the principal amount of Debentures to be
converted and the date on which such conversion is to be effected, which date
may not be prior to the date such Company Conversion Notice is deemed to have
been delivered hereunder (a "Company Conversion Date"). Each of a Company
Conversion Date and a Holder Conversion Date is referred to herein as a
"Conversion Date". If no Conversion Date is specified in a Company Conversion
Notice, the Conversion Date shall be the date that such Company Conversion
Notice is deemed delivered hereunder. Subject to the Holder's rights under
Section 4(b), the conversion subject to each Company Conversion Notice, once
given, shall be irrevocable. Not more than three Trading Days following receipt
of the Company Conversion Notice, the Holder shall deliver to the Company the
principal amount of Debentures subject to such Company Conversion Notice against
receipt of the Underlying Shares. If the Company is requiring conversion of less
than the full principal amount represented by the Debenture(s) tendered by the
Holder following a Company Conversion Notice, or if a conversion hereunder
cannot be effected in full for any reason, the Company shall honor such
conversion to the extent permissible hereunder and shall promptly deliver to
such Holder (in the manner and within the time set forth in Section 4(e)) a new
Debenture for such principal amount as has not been converted.

                 (c) Number of Underlying Shares Issuable Upon Conversion.

                     (i) The number of shares of Common Stock issuable upon a
conversion hereunder shall be determined by adding the sum of (i) the quotient
obtained by dividing (x) the principal amount of this Debenture to be converted
and (y) the Conversion Price (as defined herein), and (ii) the amount equal to
(I) the product of (x) the principal amount of this Debenture to be converted
and (y) the product of (1) .000139 and (2) the number of days for which such
principal amount was outstanding, divided by (II) the Conversion Price on the
Conversion Date, provided, that (1) if the Company shall have paid the interest
at issue in cash, subsection (ii) shall not be used in the calculation of the
number of shares of Common Stock issuable upon such conversion, and (2) only
such portion of the accrued and outstanding amount of interest owing on the
principal amount being converted shall be calculated in subsection (ii), giving
credit for previously paid interest on such principal amount.

                     (ii) Notwithstanding anything to the contrary contained
herein, if on any Conversion Date: (1) the number of shares of Common Stock at
the time authorized, unissued and unreserved for all purposes, or held as
treasury stock, is insufficient to permit issuance of the shares upon
Conversion; (2) after the Effective Date (as defined in Section 7) such shares
of Common Stock (x) are not registered for resale pursuant to an effective
Underlying Shares Registration Statement and (y) may not be sold without volume
restrictions pursuant to Rule 144(k) promulgated under the Securities Act (as
defined in Section 7), as determined by counsel to the Company pursuant to a
written opinion letter, addressed to the Company's transfer agent in the form
and substance reasonably acceptable to the applicable Holder and such transfer
agent; (3) the Common Stock is not listed or quoted for trading on the NASDAQ or
on a Subsequent Market; or (4) the issuance of such shares of Common Stock would
result in a violation of Sections 4(d)(i), (ii) or (iii), then, at the option of
the Holder, the

                                       6
<PAGE>   7

Company, in lieu of delivering shares of Common Stock pursuant to Section 4(c),
shall deliver, within ten Trading Days of each applicable Conversion Date, an
amount in cash equal to the product of (a) the outstanding principal amount of
the Debentures to be converted on such Conversion Date and (b) the product of
(x) .000139 and (y) the number of days for which such principal amount was
outstanding, less any interest previously paid in cash.

                 (d) Certain Conversion Restrictions.

                     (i) A Holder may not convert Debentures to the extent such
conversion would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 4.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon conversion of the Debentures held by such Holder after application of this
Section. Since the Holder will not be obligated to report to the Company the
number of shares of Common Stock it may hold at the time of a conversion
hereunder, unless the conversion at issue would result in the issuance of shares
of Common Stock in excess of 4.999% of the then outstanding shares of Common
Stock without regard to any other shares which may be beneficially owned by the
Holder or an affiliate thereof, the Holder shall have the authority and
obligation to determine whether the restriction contained in this Section will
limit any particular conversion hereunder and to the extent that the Holder
determines that the limitation contained in this Section applies, the
determination of which portion of the principal amount of Debentures are
convertible shall be the responsibility and obligation of the Holder. If the
Holder has delivered a Conversion Notice for a principal amount of Debentures
that, without regard to any other shares that the Holder or its affiliates may
beneficially own, would result in the issuance in excess of the permitted amount
hereunder, the Company shall notify the Holder of this fact and shall honor the
conversion for the maximum principal amount permitted to be converted on such
Conversion Date in accordance with the periods described in Section 4(b) and, at
the option of the Holder, either retain any principal amount tendered for
conversion in excess of the permitted amount hereunder for future conversions or
return such excess principal amount to the Holder. The provisions of this
Section may be waived by a Holder (but only as to itself and not to any other
Holder) upon not less than sixty-one days prior notice to the Company. Other
Holders shall be unaffected by any such waiver.

                     (ii) A Holder may not convert Debentures to the extent such
conversion would result in the Holder, together with any affiliate thereof,
beneficially owning (as determined in accordance with Section 13(d) of the
Exchange Act and the rules promulgated thereunder) in excess of 9.999% of the
then issued and outstanding shares of Common Stock, including shares issuable
upon conversion of the Debentures held by such Holder after application of this
Section. Since the Holder will not be obligated to report to the Company the
number of shares of Common Stock it may hold at the time of a conversion
hereunder, unless the conversion at issue would result in the issuance of shares
of Common Stock in excess of 9.999% of the then outstanding shares of Common
Stock without regard to any other shares which may be beneficially owned by the
Holder or an affiliate thereof, the Holder shall have the authority and
obligation to determine whether the restriction contained in

                                       7
<PAGE>   8
this Section will limit any particular conversion hereunder and to the extent
that the Holder determines that the limitation contained in this Section
applies, the determination of which portion of the principal amount of
Debentures are convertible shall be the responsibility and obligation of the
Holder. If the Holder has delivered a Conversion Notice for a principal amount
of Debentures that, without regard to any other shares that the Holder or its
affiliates may beneficially own, would result in the issuance in excess of the
permitted amount hereunder, the Company shall notify the Holder of this fact and
shall honor the conversion for the maximum principal amount permitted to be
converted on such Conversion Date in accordance with the periods described in
Section 4(b) and, at the option of the Holder, either retain any principal
amount tendered for conversion in excess of the permitted amount hereunder for
future conversions or return such excess principal amount to the Holder. The
provisions of this Section may be waived by a Holder (but only as to itself and
not to any other Holder) upon not less than sixty-one days prior notice to the
Company. Other Holders shall be unaffected by any such waiver.

                     (iii) If the Common Stock is then listed for trading on the
NASDAQ National Market or the Nasdaq SmallCap Market and the Company has not
obtained the Shareholder Approval (as defined below), then the Company is
precluded from issuing at a Conversion Price or, with respect to the Warrants
described below in this sentence, an exercise price, that is less than the
closing sales price per share of the Common Stock on the Trading Day immediately
preceding the first closing of the transactions contemplated by the Purchase
Agreement, subject to equitable adjustment in the event of stock splits and
similar events (such price, the "Market Price"), in excess of 5,160,577 shares
of Common Stock (the "Issuable Maximum") upon conversion of the Debentures and
exercise of the Warrants (as defined in the Purchase Agreement). The Issuable
Maximum equals 19.999% of the number of shares of Common Stock outstanding
immediately prior to the first closing of transactions set forth in the Purchase
Agreement. Accordingly, if on any Conversion Date (A) the Common Stock is listed
for trading on the NASDAQ or the Nasdaq SmallCap Market and (B) the Company
shall not have previously obtained the vote of shareholders (the "Shareholder
Approval"), if any, as may be required by the applicable rules and regulations
of the Nasdaq Stock Market (or any successor entity) applicable to approve the
issuance of a number of shares of Common Stock in excess of the Issuable Maximum
at a price below the Market Price, then the Company shall issue to the Holder
requesting a conversion a number of shares of Common Stock equal to the lesser
of (x) the number of shares of Common Stock issuable upon such conversion at the
Conversion Price and (y) the Issuable Maximum less all shares of Common Stock
previously issued upon conversion of the Debentures and as payment of interest
thereon (but only those shares issued at a Conversion Price less than the Market
Price) and all shares of Common Stock previously issued upon any exercise of
Warrants (but only those shares issued at an exercise price less than the Market
Price). With respect to the principal amount of Debentures tendered for
conversion at issue for which a conversion in accordance with the Conversion
Price would, when aggregated with all shares of Common Stock previously issued
on account of conversions of Debentures and payment of interest thereon and upon
exercise of Warrants (at the exercise and Conversion Price described in the
immediately preceding sentence) (the "Excess Principal"), result in the issuance
of a number of shares of Common Stock in excess of the Issuable Maximum, the
converting Holder shall have the option to require the Company

                                       8
<PAGE>   9

to either (1) use its best efforts to obtain the Shareholder Approval applicable
to such issuance as soon as is possible, but in any event not later than the
first to occur of (x) the twenty-fifth day from the date that the Commission
approves or indicates that it has no further comments to the Company's
preliminary proxy statement, if any, prepared for delivery to the shareholders
of the Company in connection with the Shareholder Approval contemplated hereby
and (y) the 90th day after such request (such date the "Approval Date"), or (2)
pay cash to the converting Holder in an amount equal to the Mandatory Prepayment
Amount for the Excess Principal. If the converting Holder shall have elected the
first option pursuant to the immediately preceding sentence and the Company
shall have failed for any reason to obtain the Shareholder Approval on or prior
to the Approval Date, then within three days of the Holder's demand therefore,
which may be given at any time following the Approval Date, the Company shall
pay cash to the converting Holder in an amount equal to the Mandatory Prepayment
Amount for the Excess Principal. If the Company fails to pay the Mandatory
Prepayment Amount in full pursuant to this Section within seven days of the date
payable, the Company will pay interest thereon at a rate of 18% per annum (or
such lesser maximum amount that is permitted to be paid by applicable law) to
the converting Holder, accruing daily from the Conversion Date until such
amount, plus all such interest thereon, is paid in full. In the event there is
more than one holder of Debentures, the Issuable Maximum applicable to each
Debenture shall be determined pro rata by reference to the percentage of the
principal amount of all Debentures held by such Holder, provided that if one or
more Debentures shall have been prepaid or converted without having been issued
its pro rata allocated portion of the Issuable Maximum such unissued shares
shall be allocated pro rata to the remaining Holders. It is understood and
agreed that shares of Common Stock delivered to and held by the Holder or one of
its affiliates on account of conversion hereunder may not cast votes on the
matter of Shareholder Approval. Shares delivered on account of conversion
hereunder and not held by the Holder or its affiliates may cast votes on the
matter of Shareholder Approval. Any Mandatory Prepayment Amount owing pursuant
to this Section shall be due and payable by the 20th day following the demand
therefor.

                 (e) Delivery of Certificates.

                     (i) Not later than three Trading Days after any Conversion
Date (a "Delivery Date"), the Company will deliver to the Holder (A) a
certificate or certificates which shall be free of restrictive legends and
trading restrictions (other than those required by Section 3.1(b) of the
Purchase Agreement or in the event that the Holder does not execute and deliver
to the Company by fax the undertaking set forth in the Company Conversion Notice
within two Trading Days after a Company Conversion Date (provided that in such
event, the Company shall cause any legend to be removed immediately upon receipt
of such undertaking)) representing the number of shares of Common Stock being
acquired upon the conversion of Debentures, (B) Debentures in a principal amount
equal to the principal amount of Debentures not converted, and (C) a bank check
in the amount of accrued and unpaid interest, provided, that the Company shall
not be obligated to issue certificates evidencing the shares of Common Stock
issuable upon conversion of the principal amount of Debentures until Debentures
are delivered for conversion to the Company, or the Holder notifies the Company
that such Debentures have been lost, stolen or destroyed and provides a bond (or
other adequate

                                       9
<PAGE>   10

security) reasonably satisfactory to the Company to indemnify the Company from
any loss incurred by it in connection therewith. The Company shall, upon request
of the Holder, if available, use its best efforts to deliver any certificate or
certificates required to be delivered by the Company under this Section
electronically through the Depository Trust Corporation or another established
clearing corporation performing similar functions. If in the case of any
Conversion Notice such certificate or certificates are not delivered to or as
directed by the applicable Holder by the Delivery Date after a Conversion Date,
the Holder shall be entitled by written notice to the Company at any time on or
before its receipt of such certificate or certificates thereafter, to rescind
such conversion, in which event the Company shall immediately return the
certificates representing the principal amount of Debentures tendered for
conversion.

                     (ii) If the Company fails to deliver to the Holder such
certificate or certificates pursuant to this Section 4 by the Delivery Date, the
Company shall pay to such Holder, in cash, as liquidated damages and not as a
penalty, $5,000 for each Trading Day after the Delivery Date until such
certificates are delivered. Nothing herein shall limit a Holder's right to
pursue actual damages or declare an Event of Default pursuant to Section 3
herein for the Company's failure to deliver certificates representing shares of
Common Stock upon conversion within the period specified herein and such Holder
shall have the right to pursue all remedies available to it at law or in equity
including, without limitation, a decree of specific performance and/or
injunctive relief. The exercise of any such rights shall not prohibit the
Holders from seeking to enforce damages pursuant to any other Section hereof or
under applicable law. Further, if the Company shall not have delivered any cash
due in respect of conversions of Debentures or as payment of interest thereon by
the Delivery Date, the Holder may, by notice to the Company, require the Company
to issue shares of Common Stock pursuant to Section 4(c), except that for such
purpose the Conversion Price applicable thereto shall be the lesser of the
Conversion Price on the Conversion Date and the Conversion Price on the date of
such Holder demand. Any such shares will be subject to the provision of this
Section.

                     (iii) In addition to any other rights available to the
Holder, if the Company fails to deliver to the Holder such certificate or
certificates pursuant to this Section 4 by the Delivery Date, and if after the
Delivery Date the Holder purchases (in an open market transaction or otherwise)
Common Stock to deliver in satisfaction of a sale by such Holder of the
Underlying Shares which the Holder anticipated receiving upon such conversion (a
"Buy-In"), then the Company shall pay in cash to the Holder (in addition to any
remedies available to or elected by the Holder) the amount by which (x) the
Holder's total purchase price (including brokerage commissions, if any) for the
Common Stock so purchased exceeds (y) the product of (1) the lesser of (A) the
aggregate number of shares of Common Stock that such Holder anticipated
receiving from the conversion at issue or (B) the number of shares of Common
Stock so purchased, multiplied by (2) the Conversion Price of the Common Stock
on the Conversion Date, in which event the number of shares of Common Stock that
would have been issued had the Company timely complied with its delivery
requirements under this Section 4 shall not be so issued. For example, if the
Holder purchases Common Stock having a total purchase price of $11,000 to cover
a Buy-In in connection with an attempted conversion

                                       10
<PAGE>   11

of Debentures with respect to which the Conversion Price of the Underlying
Shares on the applicable Conversion Date multiplied by the number of Underlying
Shares was equal to $2,000 under clause (A) of the immediately preceding
sentence, the Company shall be required to pay the Holder $9,000. The Holder
shall provide the Company written notice indicating the amounts payable to the
Holder in respect of the Buy-In. Notwithstanding anything contained herein to
the contrary, if a Holder requires the Company to make payment in respect of a
Buy-In for the failure to timely deliver certificates hereunder and the Company
timely pays in full such payment, the Company shall not be required to pay such
Holder liquidated damages under Section 4(e)(ii) in respect of the certificates
resulting in such Buy-In.

                  (f) Conversion Price; Adjustment. The Conversion Price of the
Debentures on any Conversion Date (the "Conversion Price") shall equal $4.80,
subject to adjustment as provided for in subsection (i) through (x) below and in
Section 5 hereof.

                     (i) If the Company, at any time while any Debentures are
                  outstanding, (a) shall pay a stock dividend or otherwise make
                  a distribution or distributions on shares of its Common Stock
                  or any other equity or equity equivalent securities payable in
                  shares of Common Stock (other than PIK dividend preferred
                  stock), (b) subdivide outstanding shares of Common Stock into
                  a larger number of shares, (c) combine (including by way of
                  reverse stock split) outstanding shares of Common Stock into a
                  smaller number of shares, or (d) issue by reclassification of
                  shares of the Common Stock any shares of capital stock of the
                  Company, then the Conversion Price shall be multiplied by a
                  fraction of which the numerator shall be the number of shares
                  of Common Stock (excluding treasury shares, if any)
                  outstanding before such event and of which the denominator
                  shall be the number of shares of Common Stock outstanding
                  after such event. Any adjustment made pursuant to this Section
                  shall become effective immediately after the record date for
                  the determination of stockholders entitled to receive such
                  dividend or distribution and shall become effective
                  immediately after the effective date in the case of a
                  subdivision, combination or re-classification.

                     (ii) If the Company, at any time while any Debentures are
                  outstanding, shall issue rights, options or warrants to all
                  holders of Common Stock (and not to Holders) entitling them to
                  subscribe for or purchase shares of Common Stock at a price
                  per share less than the Per Share Market Value at the record
                  date mentioned below, then the Conversion Price shall be
                  multiplied by a fraction, of which the denominator shall be
                  the number of shares of the Common Stock (excluding treasury
                  shares, if any) outstanding on the date of issuance of such
                  rights or warrants plus the number of additional shares of
                  Common Stock offered for subscription or purchase, and of
                  which the numerator shall be the number of shares of the
                  Common Stock (excluding treasury shares, if any) outstanding
                  on the date of issuance of such rights or warrants plus the
                  number of shares which the aggregate offering price of the
                  total number of shares so offered would purchase at such Per
                  Share Market Value. Such adjustment shall be made whenever
                  such rights or warrants are issued, and shall become effective
                  immediately after the record date for the determination of
                  stockholders entitled to receive such rights, options or
                  warrants. However, upon the expiration of any such

                                       11
<PAGE>   12

right, option or warrant to purchase shares of the Common Stock the issuance of
which resulted in an adjustment in the Conversion Price pursuant to this
Section, if any such right, option or warrant shall expire and shall not have
been exercised, the Conversion Price shall immediately upon such expiration be
recomputed and effective immediately upon such expiration be increased to the
price which it would have been (but reflecting any other adjustments in the
Conversion Price made pursuant to the provisions of this Section after the
issuance of such rights or warrants) had the adjustment of the Conversion Price
made upon the issuance of such rights, options or warrants been made on the
basis of offering for subscription or purchase only that number of shares of the
Common Stock actually purchased upon the exercise of such rights, options or
warrants actually exercised.

                 (iii) If the Company or any subsidiary thereof, as applicable
with respect to Common Stock Equivalents (as defined below), at any time while
Debentures are outstanding shall issue shares of Common Stock or rights,
warrants, options or other securities or debt that are convertible into or
exchangeable for shares of Common Stock ("Common Stock Equivalents"), entitling
any Person to acquire shares of Common Stock at a price per share less than the
Conversion Price (if the holder of the Common Stock or Common Stock Equivalent
so issued shall at any time, whether by operation of purchase price adjustments,
reset provisions, floating conversion, exercise or exchange prices or otherwise,
or due to warrants, options or rights issued in connection with such issuance,
be entitled to receive shares of Common Stock at a price less than the
Conversion Price, such issuance shall be deemed to have occurred for less than
the Conversion Price), then, the Conversion Price shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to the issuance of such shares of Common Stock or
such Common Stock Equivalents plus the number of shares of Common Stock which
the offering price for such shares of Common Stock or Common Stock Equivalents
would purchase at the Conversion Price, and the denominator of which shall be
the sum of the number of shares of Common Stock outstanding immediately prior to
such issuance plus the number of shares of Common Stock so issued or issuable,
provided, that for purposes hereof, all shares of Common Stock that are issuable
upon conversion exercise or exchange of Common Stock Equivalents shall be deemed
outstanding immediately after the issuance of such Common Stock Equivalents.
Such adjustment shall be made whenever such shares of Common Stock or Common
Stock Equivalents are issued. However, upon the expiration of any Common Stock
Equivalents the issuance of which resulted in an adjustment in the Conversion
Price pursuant to this Section, if any such Common Stock Equivalents shall
expire and shall not have been exercised, the Conversion Price shall immediately
upon such expiration be recomputed and effective immediately upon such
expiration be increased to the price which it would have been (but reflecting
any other adjustments in the Conversion Price made pursuant to the provisions of
this Section after the issuance of such Common Stock Equivalents) had the
adjustment of the Conversion Price made upon the issuance of such Common Stock
Equivalents been made on the basis of offering for subscription or purchase only
that number of shares of Common Stock actually purchased upon the exercise of
such

                                       12
<PAGE>   13

Common Stock Equivalents actually exercised. The foregoing shall not apply to
any (i) issuances of securities as consideration in a merger, consolidation or
acquisition of assets, or in connection with any strategic partnership or joint
venture (the primary purpose of which is not to raise equity capital), or as
consideration for the acquisition of a business, product or license by the
Company, (ii) the issuance of securities upon the exercise or conversion of the
Company's options, warrants or other convertible securities outstanding as of
the date hereof, or (iii) the grant of options or warrants, or the issuance of
additional securities, under any duly authorized Company stock option,
restricted stock plan or stock purchase plan for the benefit of the Company's
employees.

                     (iv) If the Company, at any time while Debentures are
outstanding, shall distribute to all holders of Common Stock (and not to
Holders) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security, then in each such case the Conversion
Price at which Debentures shall thereafter be convertible shall be determined by
multiplying the Conversion Price in effect immediately prior to the record date
fixed for determination of stockholders entitled to receive such distribution by
a fraction of which the denominator shall be the Per Share Market Value
determined as of the record date mentioned above, and of which the numerator
shall be such Per Share Market Value on such record date less the then fair
market value at such record date of the portion of such assets or evidence of
indebtedness so distributed applicable to one outstanding share of the Common
Stock as determined by the Board of Directors in good faith. In either case the
adjustments shall be described in a statement provided to the Holders of the
portion of assets or evidences of indebtedness so distributed or such
subscription rights applicable to one share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

                     (v) In case of any reclassification of the Common Stock or
any compulsory share exchange pursuant to which the Common Stock is converted
into other securities, cash or property, the Holders shall have the right
thereafter to, at their option, (A) convert the then outstanding principal
amount, together with all accrued but unpaid interest and any other amounts then
owing hereunder in respect of this Debenture only, into the shares of stock and
other securities, cash and property receivable upon or deemed to be held by
holders of the Common Stock following such reclassification or share exchange,
and the Holders of the Debentures shall be entitled upon such event to receive
such amount of securities, cash or property as the shares of the Common Stock of
the Company into which the then outstanding principal amount, together with all
accrued but unpaid interest and any other amounts then owing hereunder in
respect of this Debenture could have been converted immediately prior to such
reclassification or share exchange would have been entitled or (B) require the
Company to prepay the aggregate of its outstanding principal amount of
Debentures, plus all interest and other amounts due and payable thereon, at a
price determined in accordance with Section 3(b). The entire prepayment price
shall be paid in cash. This provision shall similarly apply to successive
reclassifications or share exchanges.

                                       13
<PAGE>   14

                     (vi)   All calculations under this Section 4 shall be made
to the nearest cent or the nearest 1/100th of a share, as the case may be. No
adjustments in the Conversion Price shall be required if such adjustment is less
than $0.01, provided, however, that any adjustments which by reason of this
Section are not required to be made shall be carried forward and taken into
account in any subsequent adjustment.

                     (vii)  Whenever the Conversion Price is adjusted pursuant
hereto, the Company shall promptly mail to each Holder a notice setting forth
the Conversion Price after such adjustment and setting forth a brief statement
of the facts requiring such adjustment.

                     (viii) If (A) the Company shall declare a dividend (or any
other distribution) on the Common Stock; (B) the Company shall declare a special
nonrecurring cash dividend on or a redemption of the Common Stock; (C) the
Company shall authorize the granting to all holders of the Common Stock rights
or warrants to subscribe for or purchase any shares of capital stock of any
class or of any rights; (D) the approval of any stockholders of the Company
shall be required in connection with any reclassification of the Common Stock,
any consolidation or merger to which the Company is a party, any sale or
transfer of all or substantially all of the assets of the Company, of any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property; (E) the Company shall authorize the voluntary or
involuntary dissolution, liquidation or winding up of the affairs of the
Company; then, in each case, the Company shall cause to be filed at each office
or agency maintained for the purpose of conversion of the Debentures, and shall
cause to be mailed to the Holders at their last addresses as they shall appear
upon the stock books of the Company, at least twenty calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to
such dividend, distributions, redemption, rights or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange, provided, that the
failure to mail such notice or any defect therein or in the mailing thereof
shall not affect the validity of the corporate action required to be
specified in such notice. Holders are entitled to convert Debentures during the
twenty-day period commencing the date of such notice to the effective date of
the event triggering such notice.

                     (ix)   Except as contemplated by the Merger Agreement, in
case of any (1) merger or consolidation of the Company with or into another
Person, or (2) sale by the Company of more than one-half of the assets of the
Company (based upon then fair market value) in one or a series of related
transactions, a Holder shall have the right to

                                       14
<PAGE>   15

(A) if permitted under Section 3(b) hereof, exercise its rights of prepayment
under Section 3(b) with respect to such event, or (B) convert its aggregate
principal amount of Debentures then outstanding into the shares of stock and
other securities, cash and property receivable upon or deemed to be held by
holders of Common Stock following such merger, consolidation or sale, and such
Holder shall be entitled upon such event or series of related events to receive
such amount of securities, cash and property as the shares of Common Stock into
which such aggregate principal amount of Debentures could have been converted
immediately prior to such merger, consolidation or sales would have been
entitled, or (C) in the event that the Holder shall have elected under clause
(A) above and the Company shall not have failed to pay the amounts due under
Section 3(b) by the second Business Day prior to the closing of such Change of
Control Transaction, or shall have indicated its intention to do so, then in the
case of a merger or consolidation at the closing thereof, (x) require the
surviving entity to issue shares of convertible preferred stock or convertible
debentures with such aggregate stated value or in such face amount, as the case
may be, equal to the aggregate principal amount of Debentures then held by such
Holder, plus all accrued and unpaid interest and other amounts owing thereon,
which newly issued shares of preferred stock or debentures shall have terms
identical (including with respect to conversion) to the terms of this Debenture
(except, in the case of preferred stock, as may be required to reflect the
differences between equity and debt) and shall be entitled to all of the rights
and privileges of a Holder of Debentures set forth herein and the agreements
pursuant to which the Debentures were issued (including, without limitation, as
such rights relate to the acquisition, transferability, registration and listing
of such shares of stock other securities issuable upon conversion thereof), and
(y) simultaneously with the issuance of such convertible preferred stock or
convertible debentures, shall have the right to convert such instrument only
into shares of stock and other securities, cash and property receivable upon or
deemed to be held by holders of Common Stock following such merger or
consolidation. In the case of clause (C), the conversion price applicable for
the newly issued shares of convertible preferred stock or convertible debentures
shall be based upon the amount of securities, cash and property that each share
of Common Stock would receive in such transaction and the Conversion Price in
effect immediately prior to the effectiveness or closing date for such
transaction. The terms of any such merger, sale or consolidation shall include
such terms so as to continue to give the Holders the right to receive the
securities, cash and property set forth in this Section upon any conversion or
redemption following such event. This provision shall similarly apply to
successive such events.

                 (x) In the event that at any time prior to the Third Closing
Date (as defined in the Purchase Agreement) the Exchange Ratio (as defined in
the Merger Agreement) is modified such that each share of Cereus Common Stock
(as defined in the Merger Agreement) issued and outstanding immediately prior to
the Effective Time (as defined in the Merger Agreement) shall be converted into
the right to receive, without interest, more than 1.75 fully paid and
non-assessable shares of Parent Common Stock (as defined in the Merger
Agreement), then the Conversion Price shall be decreased proportionately as
follows:

                                       15

                    CP=               PX
                                      --
                               X+((CN)-- (CO))

Where:
                    CP=        New Conversion Price;

                    P=         $4.80;

                    X=         41,606,823;

                    C=         9,023,444;

                    O=         1.75; and

                    N=         The new Exchange Ratio.

                 (g) The Company covenants that it will at all times reserve and
keep available out of its authorized and unissued shares of Common Stock solely
for the purpose of issuance upon conversion of the Debentures and payment of
interest on the Debentures, each as herein provided, free from preemptive rights
or any other actual contingent purchase rights of persons other than the
Holders, not less than such number of shares of the Common Stock as shall
(subject to any additional requirements of the Company as to reservation of such
shares set forth in the Purchase Agreement) be issuable (taking into account the
adjustments and restrictions of Section 4(b)) upon the conversion of the
outstanding principal amount of the Debentures and payment of interest
hereunder. The Company covenants that all shares of Common Stock that shall be
so issuable shall, upon issue, be duly and validly authorized, issued and fully
paid, nonassessable and, if the Underlying Shares Registration Statement has
been declared effective under the Securities Act, registered for public sale in
accordance with such Underlying Shares Registration Statement.

                 (h) Upon a conversion hereunder the Company shall not be
required to issue stock certificates representing fractions of shares of the
Common Stock, but may if otherwise permitted, make a cash payment in respect of
any final fraction of a share based on the Per Share Market Value at such time.
If the Company elects not, or is unable, to make such a cash payment, the Holder
shall be entitled to receive, in lieu of the final fraction of a share, one
whole share of Common Stock.

                 (i) The issuance of certificates for shares of the Common Stock
on conversion of the Debentures shall be made without charge to the Holders
thereof for any documentary stamp or similar taxes that may be payable in
respect of the issue or delivery of such certificate, provided that the Company
shall not be required to pay any tax that may be payable in respect of any
transfer involved in the issuance and delivery of any such certificate upon
conversion in a name other than that of the Holder of such Debentures so
converted and the Company shall

                                       16

<PAGE>   17

not be required to issue or deliver such certificates unless or until the person
or persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid.

                 (j) Any provision herein to be contrary notwithstanding, no
adjustment in the Conversion Price of the Debentures shall be made in respect of
the issuance by the Company of additional shares of Common Stock or additional
Common Stock Equivalents (i) unless the consideration per share for an
additional share of Common Stock Equivalents is less than the Conversion Price
in effect on the date of, and immediately prior to, such issue; or (ii) in any
case where the shares of Common Stock or the Common Stock Equivalents are issued
or issuable (A) upon conversions of the Debentures, (B) upon exercise of
outstanding options or warrants, (C) to any bank lender, or (D) to employees,
officers or directors of, or consultants to, the Company pursuant to stock
option or stock purchase plans or agreements or terms approved by the Company's
Board of Directors.

                 (k) Any and all notices or other communications or deliveries
to be provided by the Holders hereunder, shall be in writing and delivered
personally, by facsimile, sent by a nationally recognized overnight courier
service or sent by certified or registered mail, postage prepaid, addressed to
the Company, at 400 Galleria Parkway, Suite 300, Atlanta, GA 30339, Facsimile
No.: (703) 375-3160, attention General Counsel, or such other address or

Holder. Any notice or other communication or deliveries hereunder shall be
deemed given and effective on the earliest of (i) the date of transmission, if
such notice or communication is delivered via facsimile at the facsimile
telephone number specified in this Section prior to 6:30 p.m. (New York City

         Section 5.  Put Option; Redemption.

                 (a) If, at any time after the Original Issue Date, the Per
Share Market Value shall be less than $4.00 (as adjusted from time to time for
stock splits, stock dividends and the like) for fifteen consecutive Trading Days
then, and in such event the Holder shall at any time thereafter have the option
to require the Company to prepay this Debenture for an amount

                                       17
<PAGE>   18

equal to the Mandatory Prepayment Amount plus any and all accrued and unpaid
interest (the "Put Prepayment Amount") by notifying the Company in writing of
its election to do so (a "Put Notice"). Within five Business Days of receipt of
a Put Notice, the Company shall either pay the Put Prepayment Amount or advise
the Holder in writing (an "Election Notice") that it has elected not to prepay
this Debenture, but instead has elected to reduce the Conversion Price, in which
event the Company shall not be required to prepay this Debenture and the
Conversion Price then in effect shall thereafter be adjusted on the first day of
each month following the giving of the Put Notice to an amount which shall equal
the lesser (a) of the Conversion Price in effect on the first day of such month
or (b) the average Per Share Market Value for the last ten Trading Days of the
prior month (i.e., if the Conversion Price in effect on September 1, 2000 were
$5.50 per share and the average Per Share Market Value for the last ten Trading
Days of August 2000 were $3.25 per share, the Conversion Price would on and
after September 1, 2000 be $3.25 per share and, if the Conversion Price
thereafter remained unchanged until October 1, 2000 and the average Per Share
Market Value for the last ten Trading Days of September 2000 were $3.50 per
share the Conversion Price in effect from and after October 1, 2000 would remain
$3.25 per share, etc.)

                 (b) In the event the Company fails to deliver an Election
Notice within the prescribed period, then, and in such event, the Holder shall
have twenty business days to advise the Company in writing of its election to
receive the Put Prepayment Amount which, in such event, shall be immediately due
and payable, or to reduce the Conversion Price as provided in this Section,
retroactive to the date of the Put Notice.

                 (c) If at any time after the Original Issue Date the following
two conditions are met, the options set forth in Section 5(a) and 5(b) above, if
not previously effected, shall terminate and be of no further force and effect
(if the option set forth in Section 5(b) above shall have previously been
exercised, no further adjustment shall thereafter be required):

                     (i) The Per Share Market Value shall exceed $6.00 (as
adjusted for stock dividends or any subdivision, combination or reclassification
of the Common Stock) for a period of Twenty Consecutive Trading Days (the
"Measurement Period"); and

                     (ii) The Underlying Share Registration Statement shall have
been effective at all times during the Measurement Period.

                 (d) If the Cereus Merger shall not have been consummated on or
prior to the 150th day after the Original Issuance Date, then by notifying the
Company in writing of its election to do so (a "Redemption Notice"), the Holder
shall have, at any time thereafter, the option to require the Company to prepay
this Debenture for the "Prepayment Amount" (as defined below). The Prepayment
Amount shall equal, (i) if such prepayment is made on or before the ninetieth
day following the Redemption Notice, one-hundred percent of the principal amount
of this Debenture, (ii) if such prepayment is made after the ninetieth day but
on or before the one hundred eightieth day following the Redemption Notice, one
hundred ten percent of the principal amount of this Debenture, and (iii) if such
prepayment is made after the one hundred eightieth day following the Redemption
Notice, one hundred twenty percent of

paid in full, Holder shall have all of its rights hereunder without interruption
or modification notwithstanding its delivery of Redemption Notice.

         Section 6. Unconditional Obligation. Except as expressly provided
herein, no provision of this Debenture shall alter or impair the obligation of
the Company, which is absolute and unconditional, to pay the principal of,
interest and liquidated damages (if any) on, this Debenture at the time, place,
and rate, and in the coin or currency, herein prescribed. This Debenture is a
direct obligation of the Company. This Debenture ranks pari passu with all other
Debentures now or hereafter issued under the terms set forth herein. As long as
there are Debentures outstanding, the Company shall not and shall cause it
subsidiaries not to, without the consent of the Holders, (i) amend its
certificate of incorporation, bylaws or other charter documents so as to
adversely affect any rights of the Holders (creation of a class of preferred
stock that does not otherwise alter the relative rights, preferences or terms of
this Debenture or otherwise breach other provisions of the Transaction Documents
will not violate this clause); or (ii) enter into any agreement with respect to
the foregoing. The Company may not prepay principal amount under the Debentures
without the consent of the Holders.

         Section 11. (a) Subject to the provisions of this Section 11 relating
to payments on the Subordinated Indebtedness that are permitted to be made to
the extent and under the circumstances set forth herein, Holder hereby postpones
and subordinates all of the Subordinated Indebtedness to the full and final

Company may pay to Holder, and Holder may accept and retain, any regularly
scheduled installments of principal and interest due and owing to Holder from

including, without limitation, any Put Prepayment Amount, and (ii) Holder and
Company may exercise their rights under this Debenture to convert all or a
portion of the Subordinated Indebtedness to Common Stock.

                 (c) Company shall not be permitted to make any payments with
respect to the Debenture (other than distributions of Common Stock upon the
conversion of all or a portion of the Subordinated Indebtedness to Common
Stock), including, without limitation, any Put Prepayment Amount, and Holder
shall not be permitted to retain any payments with respect to the Debenture
(other than distributions of Common Stock upon the conversion of all or a
portion of the Subordinated Indebtedness to Common Stock) if, at the time of
making such payment or as a result thereof, any PNC Default or PNC Event of
Default exists or would exist. In no event shall any Lender's continuing to
honor any requests of Company or any other borrower for loans or other
extensions of credit under the PNC Agreement after the occurrence or existence
of any such PNC Default or PNC Event of Default be deemed a waiver thereof,
unless such PNC Default or PNC Event of Default is expressly waived in writing
by the Lenders.

                 (d) If any payment, distribution or security, or the proceeds
thereof, are received by Holder on account of or with respect to any of the
Subordinated Indebtedness other than as expressly permitted in this Section 11,
Holder shall forthwith deliver same to Agent,

                                       22
<PAGE>   23

for application to the Senior Indebtedness outstanding under the PNC Agreement,
in the form received (except for the addition of any endorsement or assignment
necessary to effect a transfer of all rights therein) or, at Agent's option,
Holder shall pay to Agent the amount thereof on demand. Until so delivered, any
such payment, distribution or security shall be held by Holder in trust for
Agent and shall not be commingled with other funds or property of Holder.

                 (e) Any amendment or modification of the terms of this Section
11 shall not be effective against any Senior Creditor unless such Senior
Creditor so consents in writing.

                 (f) No present or future Senior Creditor shall be prejudiced in
its right to enforce the provisions of this Section 11 by any act or failure to
act on the part of Company.

                 (g) Holder agrees and acknowledges that in no event shall
Holder accept, receive or otherwise obtain any Lien on any assets of Company or
any of its subsidiaries. If, notwithstanding the foregoing, Holder is granted or
otherwise acquires such a Lien, Holder agrees and acknowledges such Lien shall
be subordinated to any and all Liens held by any Senior Creditor on any such
assets.

                 (h) If the Senior Indebtedness has been indefeasibly paid and
discharged, Holder shall be subrogated (without any representation by or
recourse to any Senior Creditor) to the rights of Senior Creditors to receive
payments or distributions of cash, property or securities payable or
distributable on account of the Senior Indebtedness, to the extent of all
payments and distributions paid over to or for the benefit of Senior Creditors
pursuant to this Section 11 on account of the Subordinated Indebtedness. In no
event, however, shall Holder have any rights or claims against any Senior
Creditor for any alleged impairment of Holder's subrogation rights, Holder
acknowledging that any actions taken by a Senior Creditor with respect to the
Senior Indebtedness or the collateral securing all or any part of the Senior
Indebtedness are authorized and consented to by Holder.

                 (i) The provisions of this Debenture subordinating the
Subordinated Indebtedness are solely for the purpose of defining the relative
rights of Senior Creditors and Holder and shall not impair, as between Holder
and Company, the obligation of Company, which is unconditional and absolute, to
pay the Subordinated Indebtedness in accordance with its terms except as payment
thereof may be postponed in accordance with this Debenture.

                 (j) For purposes of this Section 11, the following terms shall

                 "Agent" shall mean PNC Bank, National Association, in its

pursuant to Rule 415. The Registration Statement shall be on Form S-3 (except if

contain (except if otherwise directed by the Holders) the "Plan of Distribution"
attached hereto as Annex A, and cause the Registration Statement to become
effective and remain effective as provided herein. The Company shall use its
best efforts to cause the Registration Statement to be declared effective under
the Securities Act as promptly as possible after the filing thereof, but in any
event prior to the Effective Date, and shall use its best efforts to keep such
Registration Statement continuously effective under the Securities Act until the
earlier of the fifth anniversary of the Closing Date therefor and such time as
all Registrable Securities covered by such Registration Statement have been sold
or may be sold without volume restrictions pursuant to Rule 144(k) as determined
by the counsel to the Company pursuant to a written opinion letter to such
effect, addressed and acceptable to the Company's transfer agent and the
affected Holders (the "Effectiveness Period"), provided, that the Company shall
not be deemed to have used its best efforts to keep the Registration Statement
effective during the Effectiveness Period if it voluntarily takes any action
that would result in the Holders not being able to sell the Registrable
Securities covered by such Registration Statement during the Effectiveness
Period, unless such action is required under applicable law or the Company has

<PAGE>   4
filed a post-effective amendment to the Registration Statement and the
Commission has not declared it effective.

          (b)  The Registration Statement shall include a number of shares of
Common Stock equal to no less than the sum of (i) 200% of the number of shares
of Common Stock issuable upon conversion in full of the principal amount of
Debentures issuable pursuant to the Purchase Agreement, and (ii) the number of
shares of Common Stock issuable upon exercise in full of the Warrants.

          (c)  If (a) the Registration Statement is not filed on or prior to the
Filing Date (if the Company files such Registration Statement without affording
the Holder the opportunity to review and comment on the same as required by
Section 3(a) hereof, the Company shall not be deemed to have satisfied this
clause (a)), or (b) the Company fails to file with the Commission a request for
acceleration in accordance with Rule 461 promulgated under the Securities Act
within five days of the date that the Company is notified (orally or in writing,
whichever is earlier) by the Commission that the Registration Statement will not
be "reviewed," or not subject to further review, or (c) the Registration
Statement filed hereunder is not declared effective by the Commission on or
prior to the Effective Date, or (d) after the Registration Statement is filed
with and declared effective by the Commission, such Registration Statement
ceases to be effective as to all Registrable Securities to be covered thereby at
any time prior to the expiration of the Effectiveness Period without being
succeeded within ten days by an amendment to such Registration Statement or by a
subsequent Registration Statement filed with and declared effective by the
Commission, or (e) the Common Stock shall be delisted or suspended from trading
on The Nasdaq National Market ("NASDAQ") or on The New York Stock Exchange, or
Nasdaq Smallcap Market (each, a "Subsequent Market") for more than five Trading
Days (which need not be consecutive days) in any twelve-month period, or (f) the
conversion rights of the Holders pursuant to the Debentures are suspended for
any reason, or (g) an amendment to a Registration Statement is not filed by the
Company with the Commission within ten days of the Commission's notifying the
Company that such amendment is required in order for such Registration Statement
to be declared effective (any such failure or breach being referred to as an
"Event," and for purposes of clauses (a), (c), (f) the date on which such Event
occurs, or for purposes of clause (b) the date on which such five day period is
exceeded, or for purposes of clauses (d) and (g) the date which such ten
day-period is exceeded, or for purposes of clause (e) the date on which such
three day-period is exceeded, being referred to as "Event Date"), then, on the
Event Date and each monthly anniversary thereof until the applicable Event is
cured, the Company shall pay to each Holder 2.0% of the purchase price paid by
such Holder pursuant to the Purchase Agreement, in cash, as liquidated damages
and not as a penalty. Notwithstanding the foregoing, (a) in the event the
Company has and continues to use its best efforts to cause the Registration
Statement to be declared effective, no liquidated damages shall be due for
periods prior to the 110th day following the First Closing Date and (b) the
liquidated damages for the first monthly period after the Effective Date, or any
portion thereof, shall be at the rate of 1% of the purchase price paid by such
Holder pursuant to the Purchase Agreement. If the Company fails to pay any
liquidated damages pursuant to this Section in full within five days after the
date payable, the Company will pay interest thereon at a rate of 18% per annum
(or

                                       4
<PAGE>   5

such lesser maximum amount that is permitted to be paid by applicable law) to
the Holder, accruing daily from the date such liquidated damages are due until
such amounts, plus all such interest thereon, are paid in full. The liquidated
damages pursuant to the terms hereof shall apply on a pro-rata basis for any
portion of a month prior to the cure of an Event.

          (d)  Notwithstanding the foregoing, the Company may suspend offers and
sales or delay the effectiveness of any Registration Statement, an aggregate of
up to sixty Trading Days in any 12-month period, if the Company's Board of
Directors determines, in good faith, that such delay would be necessary to avoid
premature disclosure of any material acquisition, disposition, business
combination, or other material transaction, and such delay or suspension will
not result in an Event hereunder (however, no such delay will provide the basis
for avoidance of an Event of Default under Section 3(a)(viii) of the
Debentures).

     3.   Registration Procedures

          In connection with the Company's registration obligations hereunder,
the Company shall:

          (a)  Not less than five Business Days prior to the filing of the
Registration Statement or any related Prospectus or any amendment or supplement
thereto, the Company shall, (i) furnish to the Holders and their Special Counsel
copies of all such documents proposed to be filed, which documents (other than
those incorporated or deemed to be incorporated by reference) will be subject to
the review of such Holders and their Special Counsel, and (ii) cause its
officers and directors, counsel and independent certified public accountants to
respond to such inquiries as shall be necessary, in the reasonable opinion of
Special Counsel to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file a Registration Statement or any such
Prospectus or any amendments or supplements thereto to which the Holders of a
majority of the Registrable Securities to be covered thereby and their Special
Counsel shall reasonably object.

          (b)  (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement and the
Prospectus used in connection therewith as may be necessary to keep such
Registration Statement continuously effective for the Effectiveness Period; (ii)
cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424; (iii) respond as promptly as reasonably possible, and in any event
within ten days, to any comments received from the Commission with respect to
the Registration Statement or any amendment thereto and as promptly as
reasonably possible provide the Holders true and complete copies of all
correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
Effectiveness Period in accordance with the intended methods of disposition by
the Holders thereof set forth in the Registration Statement as so amended or in
such Prospectus as so supplemented.

                                      5

<PAGE>   6

          (c)  File additional Registration Statements if the number of
Registrable Securities to be covered by a Registration Statement at any time
exceeds 85% of the number of shares of Common Stock then registered in such
Registration Statement. The Company shall have twenty days to file such
additional Registration Statements after such requirement notice is received by
the Company (which shall be the Filing Date for such additional Registration
Statements) and the Effectiveness Date for each such additional Registration
Statement shall be the 90th day following the date of such notice.

          (d)  Notify the Holders Special Counsel as promptly as reasonably
possible (and, in the case of (i)(A) below, not less than five Business Days
prior to such filing) and (if requested by any such Person) confirm such notice
in writing no later than one Business Day following the day (i)(A) when the
Commission notifies the Company whether there will be a "review" of such
Registration Statement and whenever the Commission comments in writing on such
Registration Statement (the Company shall provide true and complete copies
thereof and all written responses thereto to Special Counsel); and (B) with
respect to the Registration Statement or any post-effective amendment, when the
same has become effective; (ii) of any request by the Commission or any other
Federal or state governmental authority for amendments or supplements to the
Registration Statement or Prospectus or for additional information; (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iv) if at any time any of the
representations and warranties of the Company contained in the Transaction
Documents ceases to be true and correct in all material respects; (v) of the
receipt by the Company of any notification with respect to the suspension of the
qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose; and (vi) of the occurrence of any event or passage
of time that makes the financial statements included in the Registration
Statement ineligible for inclusion therein or any statement made in the
Registration Statement or Prospectus or any document incorporated or deemed to
be incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any 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.

          (e)  Use its best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of (i) any order suspending the effectiveness of each
Registration Statement, or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

          (f)  Furnish to each Holder and their Special Counsel, without charge,
at least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person

                                       6

<PAGE>   7

(including those previously furnished or incorporated by reference) promptly
after the filing of such documents with the Commission.

          (g)  Promptly deliver to each Holder and their Special Counsel,
without charge, as many copies of the Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Persons may
reasonably request. The Company hereby consents to the use of such Prospectus
and each amendment or supplement thereto by each of the selling Holders in
connection with the offering and sale of the Registrable Securities covered by
such Prospectus and any amendment or supplement thereto.

          (h)  Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders and
their Special Counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder requests in writing, to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided that the
Company shall not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

          (i)  Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be delivered
to a transferee pursuant to a Registration Statement, which certificates shall
be free, to the extent permitted by the Purchase Agreement, of all restrictive
legends, and to enable such Registrable Securities to be in such denominations
and registered in such names as any such Holders may request.

          (j)  Upon the occurrence of any event contemplated by Section 3(d)
(vi), as promptly as reasonably possible, prepare a supplement or amendment,
including a post-effective amendment, to a Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other required document so
that, as thereafter delivered, neither such Registration Statement nor such
Prospectus will contain an 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 light of the circumstances under which they were made,
not misleading.

          (k)  Comply with all applicable rules and regulations of the
Commission in connection with its obligations hereunder.

          (l)  The Company may require each selling Holder to complete a selling
shareholder questionnaire in reasonable and customary form furnishing to the
Company a certified statement as to the number of shares of Common Stock
beneficially owned by such Holder and such other information reasonably
necessary for the preparation of the Registration Statement and, if requested by
the Commission, the controlling person of such Holder.

Prospectus or form of prospectus or supplement thereto, in light of the

but only to the extent, that (1) such untrue statements or omissions are based
solely upon information regarding such Holder furnished in writing to the
Company by such Holder expressly for use therein, or to the extent that such

Prospectus or such form of Prospectus or in any amendment or supplement thereto
or (2) in the case of an

                                       8

<PAGE>   9
occurrence of an event of the type specified in Section 3(d)(ii)-(vi), the use
by such Holder of an outdated or defective Prospectus after the Company has
notified such Holder in writing that the Prospectus is outdated or defective and
prior to the receipt by such Holder of the Advice contemplated in Section 6(e).
The Company shall notify the Holders promptly of the institution, threat or
assertion of any Proceeding of which the Company is aware in connection with the
transactions contemplated by this Agreement.

          (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in such Registration Statement, any
Prospectus, or any form of prospectus, or in any amendment or supplement
thereto, or arising solely out of or based solely upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in such Registration
Statement or such Prospectus or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in such Registration Statement, such Prospectus or such form
of Prospectus, or in any amendment or supplement thereto. In no event shall the
liability of any selling Holder hereunder be greater in amount than the dollar
amount of the net proceeds received by such Holder upon the sale of the
Registrable Securities giving rise to such indemnification obligation.

          (c) Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party shall promptly notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided that the
failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court
of competent jurisdiction (which determination is not subject to appeal or
further review) that such failure shall have proximately and materially
adversely prejudiced the Indemnifying Party.

          (d) Separate Counsel. An Indemnified Party shall have the right to
employ separate counsel in any such Proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed
in writing to pay such fees and expenses; or (2) the Indemnifying Party shall
have failed promptly to assume the defense of such Proceeding

                                       9

<PAGE>   10

and to employ counsel reasonably satisfactory to such Indemnified Party in any
such Proceeding; or (3) the named parties to any such Proceeding (including any
impleaded parties) include both such Indemnified Party and the Indemnifying
Party, and such Indemnified Party shall have been advised by written opinion of
counsel that a conflict of interest is likely to exist if the same counsel were
to represent such Indemnified Party and the Indemnifying Party (in which case,
if such Indemnified Party notifies the Indemnifying Party in writing that it
elects to employ separate counsel at the expense of the Indemnifying Party, the
Indemnifying Party shall not have the right to assume the defense thereof and
such counsel, who shall represent all other Indemnified Parties who are
similarly situated and who can be represented without conflict by such counsel,
shall be at the expense of the Indemnifying Party). The Indemnifying Party shall
not be liable for any settlement of any such Proceeding effected without its
written consent, which consent shall not be unreasonably withheld. No
Indemnifying Party shall, without the prior written consent of the Indemnified
Party, effect any settlement of any pending Proceeding in respect of which any
Indemnified Party is a party, unless such settlement includes an unconditional
release of such Indemnified Party from all liability on claims that are the
subject matter of such Proceeding.

          (e) Fees and Expenses of Indemnified Party. All fees and expenses of
the Indemnified Party (including reasonable fees and expenses to the extent
incurred in connection with investigating or preparing to defend such Proceeding
in a manner not inconsistent with this Section) shall be paid to the Indemnified
Party, as incurred, within ten Business Days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

          (f) Contribution. If a claim for indemnification under Section 5(a) or
5(b) is unavailable to an Indemnified Party (by reason of public policy or
otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission. The amount paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or other
reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to
such party in accordance with its terms. The parties hereto agree that it would
not be just and equitable if contribution

                                       10
<PAGE>   11

pursuant to this Section 5(f) were determined by pro rata allocation or by any
other method of allocation that does not take into account the equitable
considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(f), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

          (g)  Non-Exclusive Remedy. The indemnity and contribution agreements
contained in this Section are in addition to any liability that the Indemnifying
Parties may have to the Indemnified Parties.

     6.   Miscellaneous

          (a)  Remedies. In the event of a breach by the Company or by a Holder,
of any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

          (b)  No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has entered, as of the date hereof, nor shall the Company or any of
its subsidiaries, on or after the date of this Agreement, enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. Except as and to the extent specified in Schedule 6(b)
hereto, neither the Company nor any of its subsidiaries has previously entered
into any agreement granting any registration rights with respect to any of its
securities to any Person.

          (c)  No Piggyback on Registrations. Except as and to the extent
specified in Schedule 6(b) hereto, neither the Company nor any of its security
holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in the Registration Statement other than the
Registrable Securities, and the Company shall not after the date hereof enter
into any agreement providing any such right to any of its security holders.

          (d)  Compliance. Each Holder covenants and agrees that it will comply
with the prospectus delivery requirements of the Securities Act as applicable to
it in connection with sales of Registrable Securities pursuant to the
Registration Statement.

                                       11

<PAGE>   12

          (e)  Discontinued Disposition. Each Holder agrees by its acquisition
of such Registrable Securities that, upon receipt of a notice from the Company
of suspension under Section 2(d) or of the occurrence of any event of the kind
described in Sections 3(d)(ii), 3(d)(iii), 3(d)(iv), 3(d)(v) or 3(d)(vi), such
Holder will forthwith discontinue disposition of such Registrable Securities
under the Registration Statement until such Holder's receipt of the copies of
the supplemented Prospectus and/or amended Registration Statement contemplated
by Section 3(j), or until it is advised in writing (the "Advice") by the Company
that the use of the applicable Prospectus may be resumed, and, in either case,
has received copies of any additional or supplemental filings that are
incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement. The Company may provide appropriate stop orders to
enforce the provisions of this paragraph.

          (f)  Piggy-Back Registrations. If at any time during the Effectiveness
Period there is not an effective Registration Statement covering all of the
Registrable Securities and the Company shall determine to prepare and file with
the Commission a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or their then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, then the Company shall send to each Holder written notice of such
determination and, if within fifteen days after receipt of such notice, any such
Holder shall so request in writing, the Company shall include in such
registration statement all or any part of such Registrable Securities such
holder requests to be registered, subject to customary underwriter cutbacks
applicable to all holders of registration rights.

          (g)  Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of at least two-thirds of the then outstanding Registrable
Securities. Notwithstanding the foregoing, a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders and that does not directly or indirectly affect the rights of
other Holders may be given by Holders of at least a majority of the Registrable
Securities to which such waiver or consent relates; provided, however, that the
provisions of this sentence may not be amended, modified, or supplemented except
in accordance with the provisions of the immediately preceding sentence.

          (h)  Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed given and effective on the earliest of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in this Section prior to 6:30 p.m. (New

          If to a Purchaser:            To the address set forth under such
                                        Purchaser's name on the signature
                                        pages hereto.

If to any other Person who is then the registered Holder:

          To the address of such Holder as it appears in the stock transfer
books of the Company or such other address as may be designated in writing
hereafter, in the same manner, by such Person.

          (i)  Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and permitted assigns of each of the
parties and shall inure

                                       13

<PAGE>   14

to the benefit of each Holder. The Company may not assign its rights or
obligations hereunder without the prior written consent of each Holder. Each
Holder may assign their respective rights hereunder in the manner and to the
Persons as permitted under the Purchase Agreement.

          (j)  Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement. In
the event that any signature is delivered by facsimile transmission, such
signature shall create a valid binding obligation of the party executing (or on
whose behalf such signature is executed) the same with the same force and effect
as if such facsimile signature were the original thereof.

          (k)  Governing Law. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by
and construed and enforced in accordance with the internal laws of the State of
New York, without regard to the principles of conflicts of law thereof. Each
party hereby irrevocably submits to the exclusive jurisdiction of the state and
federal courts sitting in the City of New York, borough of Manhattan, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law.

          (l)  Cumulative Remedies. The remedies provided herein are cumulative
and not exclusive of any remedies provided by law.

          (m)  Severability. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

          (n)  Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (o)  Shares Held by the Company and its Affiliates. Whenever the
consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than any Holder or

                                       14

<PAGE>   15
transferees or successors or assigns thereof if such Holder is deemed to be an
Affiliate solely by reason of its holdings of such Registrable Securities) shall
not be counted in determining whether such consent or approval was given by the
Holders of such required percentage.

          (p)  Independent Nature of Purchasers' Obligations and Rights. The
obligations of each Purchaser hereunder is several and not joint with the
obligations of any other Purchaser hereunder, and neither Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser hereunder. Nothing contained herein or in any other agreement or
document delivered at any closing, and no action taken by any Purchaser pursuant
hereto or thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert with
respect to such obligations or the transactions contemplated by this Agreement.
Each Purchaser shall be entitled to protect and enforce its rights, including
without limitation the rights arising out of this Agreement, and it shall not be
necessary for any other Purchaser to be joined as an additional party in any
proceeding for such purpose.

                              PLAN OF DISTRIBUTION

          The Selling Stockholders and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
of Common Stock on any stock exchange, market or trading facility on which the
shares are traded or in private transactions. These sales may be at fixed or
negotiated prices. The Selling Stockholders may use any one or more of the
following methods when selling shares:

          -    ordinary brokerage transactions and transactions in which the
               broker-dealer solicits purchasers;

          -    block trades in which the broker-dealer will attempt to sell the
               shares as agent but may position and resell a portion of the
               block as principal to facilitate the transaction;

          -    purchases by a broker-dealer as principal and resale by the
               broker-dealer for its account;

          -    an exchange distribution in accordance with the rules of the
               applicable exchange;

          -    privately negotiated transactions;

          -    short sales;

          -    broker-dealers may agree with the Selling Stockholders to sell a
               specified number of such shares at a stipulated price per share;

          -    a combination of any such methods of sale; and

          -    any other method permitted pursuant to applicable law.

          The Selling Stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

          The Selling Stockholders may also engage in short sales against the
box, puts and calls and other transactions in securities of the Company or
derivatives of Company securities and may sell or deliver shares in connection
with these trades. The Selling Stockholders may pledge their shares to their
brokers under the margin provisions of customer agreements. If a Selling
Stockholder defaults on a margin loan, the broker may, from time to time, offer
and sell the pledged shares.

          Broker-dealers engaged by the Selling Stockholders may arrange for
other brokers-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the Selling Stockholders (or, if any broker-dealer
acts as agent for the purchaser of

<PAGE>   20

shares, from the purchaser) in amounts to be negotiated. The Selling
Stockholders do not expect these commissions and discounts to exceed what is
customary in the types of transactions involved.

          The Selling Stockholders and any broker-dealers or agents that are
involved in selling the shares may be deemed to be "underwriters" within the
meaning of the Securities Act in connection with such sales. In such event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act.

          The Company is required to pay all fees and expenses incident to the
registration of the shares, including fees and disbursements of counsel to the
Selling Stockholders. The Company has agreed to indemnify the Selling
Stockholders against certain losses, claims, damages and liabilities, including
liabilities under the Securities Act.
