reduce the principal of or rate of interest on any Note or (ii) postpone the
date fixed for any payment of principal on any Note or of interest on any Note.

     Section 10.08. Successors And Assigns; Registration. (a) The provisions of
this Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns (including any transferee of
any Note), except that the Company may not assign or otherwise transfer any of
its rights under this Agreement without the prior written consent of the
Required Holders.

     (b) Either of the Purchasers may at any time assign or transfer all, or a
proportionate part of all of its rights and obligations under this Agreement and
the Notes only with the prior written consent of the Company and each other
Purchaser (each, a "NON-ASSIGNING PURCHASER"), which consent shall not be
unreasonably withheld or delayed; provided that the consent of the Company and
the Non-Assigning Purchasers shall not be required for such assignments or
transfers (i) to an Affiliate of a Purchaser or (ii) to another Purchaser.
Subject to the restriction contained in the foregoing sentence, the terms and
provisions of this Agreement shall inure to the benefit of any transferee or
assignee of any Note and, in the event of such transfer or assignment, the
rights and privileges herein conferred upon the assigning Purchaser shall
automatically extend to and be vested in such transferee or assignee, all such
to the terms and conditions hereof.

     (c) Upon any assignment of any Note, the assigning Purchaser shall
surrender its Note to the Company for exchange or registration of transfer, and
the Company will promptly execute and deliver in exchange therefor a new Note or
Note of the same tenor, and registered in the name of the assignor Purchaser (if
less than all of such Purchaser's Notes are assigned) and the name of the
assignee Purchaser.

     (d) The Company shall maintain a register (the "NOTE REGISTER") of the
Purchasers and all assignee Purchasers that are the holders of all the Notes
issued pursuant to this Agreement. The Company will allow any Purchaser to
inspect and copy such list at the Company's principal place of business during
normal business hours. Prior to the due presentment for registration of transfer
of any Note, the Company may deem and treat the Person in whose name a Note is
registered as the absolute owner of such Note for the purpose of receiving
payment of principal of and premium and interest on such Note and for all other
purposes whatsoever, and the Company shall not be affected by notice to the
contrary.

     (e) Each Purchaser (including any assignee Purchaser at the time of such
assignment) represents that it (i) is acquiring its Note solely for investment
purposes and not with a view toward, or for sale in connection with, any
distribution thereof, (ii) has received and reviewed such information as it
deems necessary to evaluate the merits and risks of its investment in the Notes,
(iii) is an "accredited investor" within the meaning of Rule 501(a) under the
Securities Act, and (iv) has such knowledge and experience in financial and
business matters as to be capable of evaluating the merits and risks of its
investment in the Notes, including a complete loss of its investment.

     (f) Each Purchaser understands that the Notes are being offered only in a
transaction not involving any public offering within the meaning of the
Securities Act, and that, if in the future such Purchaser decides to resell,
pledge or otherwise transfer any of the Notes, such Notes may be resold, pledged
or transferred only (i) to the Company, (ii) to a person who such Purchaser
reasonably believes is a qualified institutional buyer that purchases for its
own account or for the account of a qualified institutional buyer to whom notice
is given that such resale, pledge or transfer is being made in reliance on Rule
144A under the Securities Act, or (iii) pursuant to an exemption from
registration under the Securities Act.

     (g) Each Purchaser understands that the Notes will, unless otherwise agreed
by the Company and the holder thereof, bear a legend to the following effect:

     THIS SECURITY IS NOT BEING REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "SECURITIES ACT").  THE HOLDER HEREOF, BY PURCHASING THIS SECURITY,
AGREES FOR THE BENEFIT OF THE ISSUER THAT THIS SECURITY MAY BE RESOLD, PLEDGED
OR OTHERWISE TRANSFERRED, ONLY (1) TO THE COMPANY OR (2) PURSUANT TO AN
EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT.

     Section 10.09. Lost Or Destroyed Notes. If any Note becomes mutilated and
is surrendered by the Purchaser with respect thereto to the Company, or if any
Purchaser claims that its Note has been lost, destroyed or wrongfully taken, the
Company shall execute and deliver to such Purchaser a replacement Note, upon
the affidavit of such Purchaser attesting to such loss, destruction or wrongful
taking with respect to such Note and such lost, destroyed, mutilated,
surrendered or wrongfully taken Note shall be deemed to be canceled for all
purposes hereof.
                                       34

Such affidavit shall be accepted as satisfactory evidence of the loss, wrongful
taking or destruction thereof and no indemnity shall be required as a condition
of the execution and delivery of a replacement Note. Any costs and expenses of
the Company in replacing any such Note shall be for the account of such
Purchaser.

     Section 10.10.  Headings.  Headings and captions used in the Financing
Documents (including the Exhibits and Schedules hereto and thereto) are included
for convenience of reference only and shall not be given any substantive effect.

     Section 10.11. Confidentiality. In handling any confidential information of
the Company or any of its Subsidiaries, the Purchasers shall exercise the same
degree of care that it exercises with respect to its own proprietary information
of the same types to maintain the confidentiality of any non-public information
thereby received or received pursuant to this Agreement except that disclosure
of such information may be made (i) to the agents, employees, Subsidiaries or
Affiliates of such Person in connection with its present or prospective business
relations with the Company and its Subsidiaries arising out of the Financing
Documents, but only to the extent that each such agent, employee, Subsidiary or
Affiliate has been directed to maintain the confidentiality of such information
in accordance with the provisions of this Section 10.11, (ii) to prospective
transferees or purchasers of any interest in the Notes, provided that they have
agreed to be bound by the provision of this Section 10.11, (iii) as required by
law, regulations, rule, request or order, subpoena, judicial order or similar
order and in connection with any litigation, and (iv) as may be required in
connection with the examination, audit or similar investigation of such Person.
The Purchasers will not use or allow the use of confidential information for any
purpose except in connection with the transactions and agreements contemplated
by the Financing Documents. Confidential information shall include only such
information identified as such in writing at the time provided to the Purchasers
or upon written notice to the Purchasers at any time thereafter and shall not
include information that either: (i) is in the public domain, or becomes part of
the public domain after disclosure to such Person through no fault of such
Person or (ii) is disclosed to such Person by a third party, provided the
Purchasers do not have actual knowledge that such third party is prohibited from
disclosing such information.

                     12% Convertible, Senior, Secured Note
                             Due December 31, 2007

U.S. $_______                                                   October __, 2001

     FOR VALUE RECEIVED, the undersigned, NaviSite, Inc., a Delaware corporation
(the "COMPANY"), hereby promises to pay to __, a Delaware corporation (the
"PURCHASER"), the principal sum of US$____ in twelve equal quarterly
installments (each a "PRINCIPAL PAYMENT"), together with accrued but unpaid
interest thereon, commencing on the first Interest Payment Date (as defined
below) in 2005 and continuing on each Interest Payment Date thereafter (each
date on which a Principal Payment is made, a "PRINCIPAL PAYMENT DATE")
<PAGE>

until December 31, 2007 (the "MATURITY DATE"). The Company may not prepay this
Note. Interest on the outstanding principal shall be at a rate of 12% per annum
("INTEREST"), calculated on the basis of a 360 day year consisting of twelve 30
day months, and will be payable quarterly in arrears on March 31, June 30,
September 30 and December 31 of each year (each an "INTEREST PAYMENT DATE")
beginning December 31, 2001 until the Maturity Date. Interest for first Interest
Payment Date shall be calculated from the date of issuance hereof to the first
Interest Payment Date. If all or a portion of a Principal Payment or Interest
shall not be paid when due (whether at its stated maturity, by acceleration or
otherwise), the Company hereby promises to pay, on demand, interest on such
overdue amount from and including the due date to, but excluding, the date such
amount is paid in full at 14% per annum (and until the date such overdue amount
is paid in full, "Interest" on such overdue amount shall mean interest at such
rate).

     This Note is being delivered pursuant to a Note Purchase Agreement, dated
as of October 29, 2001, among the Company, the Purchaser and [CFS/CMGI] (the
"NOTE PURCHASE AGREEMENT").  This Note is one of the Notes referred to in the
Note Purchase Agreement, which among other things, contains provisions for the
acceleration of the maturity hereof upon the happening of certain events and for
the amendment or waiver of certain provisions of the Note Purchase Agreement,
all upon the terms and conditions therein specified.

     1. Certain Definitions. As used herein, the following terms have the
following meanings:

     "CLOSING PRICE" shall mean, on any day, (i) the closing price of the Common
Stock (or any other security for which a closing price must be determined) on a
national securities exchange or as quoted on the Nasdaq National Market on such
day, as reported by the Wall Street Journal or (ii) if the Common Stock (or any
such other security) is quoted on the Nasdaq National Market but no sale occurs
on such day, the average of the closing bid and asked prices of the Common Stock
(or any such other security) on the Nasdaq National Market on such day, as
reported by the Wall Street Journal or (iii) if the Common Stock (or any such
other security) is not so listed or quoted, the average of the closing bid and
asked prices of the Common Stock (or any such other security) in the U.S. over-
the-counter market or (iv) if no such trading market is readily available, the
fair market value of the Common Stock (or any such other security) as determined
in accordance with Section 5(b) hereof.

     "CURRENT MARKET PRICE" of the Common Stock means the average of the daily
Closing Prices of the Common Stock for the five consecutive trading days
selected by the board of directors commencing not more than 20 trading days
before, and ending not later than the date immediately preceding the record date
fixed in connection with such event or, if there is no record date, the date of
such event; provided, that the Current Market Price of the Common Stock in
connection with a Spin-Off shall mean the average of the daily Closing Prices of

                                       2
<PAGE>

the Common Stock for the same five consecutive trading days used to determine
the Fair Market Value of the securities being distributed in such Spin-Off.

     "FAIR MARKET VALUE" of the securities to be distributed to the holders of
the Common Stock in connection with a Spin-Off shall mean the average of the
daily Closing Prices of such securities for a five consecutive trading day
period selected by the board of directors during the period beginning on the
first day of trading of such securities after the effectiveness of such Spin-Off
and ending not later than 20 days after the effectiveness of the Spin-Off.

     All capitalized terms used but not otherwise defined herein shall have the
meaning ascribed to such terms in the Note Purchase Agreement.

     2. Security.

     The Purchaser's right to payment pursuant to the terms of this Note shall
be secured to the extent and on the terms and conditions set forth in the
Security Agreement, and the terms and provisions of the Security Agreement are
incorporated herein by reference.

     3. Payment.

     Principal Payments on each Principal Payment Date and Interest on each
Interest Payment Date shall be made by bank cashier's check payable to the
Purchaser at the Purchaser's principal address set forth in Section 10.04 of the
Note Purchase Agreement (or at such other place as the Purchaser hereof shall
notify the Company in writing) or, if the Purchaser so specifies, by written
notice to the Company given not less than two Business Days prior to the
Principal Payment Date or the Interest Payment Date, as the case may be, by bank
wire transfer, in immediately available funds, to the account so specified, in
lawful money of the United States of America; provided that, at the election of
the Company, so long as the Company is listed on the Nasdaq National Market, up
to [one-sixth - CFS Note]/[100% - CMGI Note] of the amount of Interest due on
any Interest Payment Date through and including the Interest Payment Date in
December [2003 -CFS Note]/[2007-CMGI Note] may be paid in shares of Common
Stock.  The number of shares of Common Stock to be issued in payment of the
Interest due on such Interest Payment Date shall equal the amount of such
Interest to be paid in Common Stock divided by the average of the Closing Prices
per share of the Common Stock on the five consecutive trading days ending on the
trading day immediately preceding such Interest Payment Date.  If any Principal
Payment Date or any Interest Payment Date occurs on a date that is not a
Business Day, then the Principal Sum or Interest then due shall be paid on the
next succeeding Business Day.

     4. Conversion.

                                       3
<PAGE>

     (a) Conversion Rights. Subject to and in accordance with the provisions of
this Section 4, at any time on or prior to the Maturity Date, the Purchaser may
elect, in its sole discretion, to effect the conversion (the "CONVERSION") of
all or any portion of the outstanding principal and interest due on this Note
into shares of Common Stock. The number of shares of Common Stock into which the
outstanding principal and accrued but unpaid interest (or portion thereof) shall
be converted pursuant to this Section 4(a) shall be determined by dividing the
amount of outstanding principal and interest the Purchaser has elected to
convert by $0.26. The Conversion Price is subject to adjustment as provided in
Section 5 hereof.

     (b) Manner of Effecting the Conversion. If the Purchaser elects to effect
the Conversion pursuant to Section 4(a) hereof, the Purchaser shall deliver a
duly executed written notice to the Company of such election (the "CONVERSION
NOTICE"), and in such event the Conversion shall be deemed to have been effected
at the close of business on the date such Conversion Notice is given. Upon any
Conversion of this Note in accordance with the terms hereof, the rights of the
Purchaser with respect to the outstanding principal and all interest pursuant to
this Note shall cease and the Purchaser shall be deemed to have become the
holder of record of the shares of Common Stock into which this Note shall have
been converted, provided that, if the Purchaser elects to convert only a portion
of the outstanding principal and interest pursuant to Section 4(a) hereof, then
the Company will deliver a new note to the Purchaser, on the same terms and
conditions as this Note, with respect to the portion of the outstanding
principal and interest that is not converted (the "NEW NOTE"). Concurrently with
the delivery of a Conversion Notice, the Purchaser shall surrender this Note to
the Company. Promptly upon its receipt of a Conversion Notice, the Company shall
(i) deliver to or upon the written order of the Purchaser, a certificate or
certificates for the number of shares of Common Stock issuable upon such
Conversion, (ii) make a cash payment in respect of any fraction of a share as
provided in Section 4(c) hereof and (iii) if applicable, deliver a New Note as
set forth in this Section 4(b).

     (c) Fractional Shares. No fractional shares shall be issued upon any
Conversion. Instead of any fractional share which would otherwise be issuable
upon a Conversion, the Company shall pay a cash amount in respect of such
fractional share in an amount based upon the Closing Price of the Common Stock
on the trading day immediately preceding such Conversion.

     (d) Notwithstanding anything contained herein, this Note may not be
converted until the Company has obtained the stockholder approvals required in
accordance with Rule 4350(i) of the National Association of Securities Dealers
Manual and Delaware corporate law.

     5. Antidilution Provisions.

     (a) The Conversion Price shall be subject to adjustment from time to time
as follows:

          (i) STOCK SPLITS AND COMBINATIONS. In case the Company shall at any
     time or from time to time after the Closing Date (A) subdivide or split the
     outstanding shares of Common Stock, (B) combine or reclassify the
     outstanding shares of Common Stock into a smaller number of shares or (C)
     issue by reclassification of the shares of Common Stock any shares of
     Capital Stock of the Company, then, and in each such case, the Conversion
     Price in effect immediately prior to such event or the record date
     therefor, whichever is earlier, shall be adjusted so that the holder of
     this Note thereafter surrendered for conversion shall be entitled to
     receive the number of shares of Common Stock or other securities of the
     Company which such holder would have owned or have been entitled to receive
     after the occurrence of any of the events described above, had such Note
     been surrendered for conversion immediately prior to the occurrence of such
     event or the record date therefor, whichever is earlier. An adjustment made
     pursuant to this subparagraph (i) shall become effective at the close of
     business on the day upon which such corporate action becomes effective.
     Such adjustment shall be made successively whenever any event listed above
     shall occur.

          (ii) STOCK DIVIDENDS IN COMMON STOCK. In case the Company shall at any
     time or from time to time after the Closing pay a dividend or make a
     distribution in shares of Common Stock on any class of Capital Stock of the
     Company other than dividends or distributions of shares of Common Stock or
     other securities with respect to which adjustments are provided in Section
     5(a)(i) above, the Conversion Price shall be adjusted so that the holder of
     this Note shall be entitled to receive upon conversion thereof, the number
     of shares of Common Stock determined by multiplying (A) the applicable
     Conversion Price by (B) a fraction, the numerator of which shall be the
     number of shares of Common Stock theretofore outstanding and the
     denominator of which shall be the sum of such number of shares and the
     total number of shares issued in such dividend or distribution.

          (iii) ISSUANCE OF RIGHTS OR WARRANTS. In case the Company shall issue
     to all holders of Common Stock rights or warrants entitling such holders to
     subscribe for or purchase Common Stock at a price per share less than the
     Current Market

                                       5
<PAGE>

     Price, the Conversion Price in effect immediately prior to the close of
     business on the record date fixed for determination of stockholders
     entitled to receive such rights or warrants shall be reduced by multiplying
     such Conversion Price by a fraction, the numerator of which is the sum of
     the number of shares of Common Stock outstanding at the close of business
     on such record date and the number of shares of Common Stock that the
     aggregate offering price of the total number of shares of Common Stock so
     offered for subscription or purchase would purchase at such Current Market
     Price and the denominator of which is the sum of the number of shares of
     Common Stock outstanding at the close of business on such record date and
     the number of additional shares of Common Stock so offered for subscription
     or purchase. For purposes of this subparagraph (iii), the issuance of
     rights or warrants to subscribe for or purchase securities convertible into
     Common Stock shall be deemed to be the issuance of rights or warrants to
     purchase the Common Stock into which such securities are convertible at an
     aggregate offering price equal to the sum of the aggregate offering price
     of such securities and the minimum aggregate amount (if any) payable upon
     conversion of such securities into Common Stock. Such adjustment shall be
     made successively whenever any such event shall occur.

          (iv) DISTRIBUTION OF INDEBTEDNESS, SECURITIES OR ASSETS. In case the
     Company shall distribute to all holders of Common Stock (whether by
     dividend or in a merger, amalgamation or consolidation or otherwise)
     evidences of indebtedness, shares of Capital Stock of any class or series,
     other securities, cash or assets (other than Common Stock, rights or
     warrants referred to in subparagraph (iii) above and other than as a result
     of a Fundamental Change (as defined below)), the Conversion Price in effect
     immediately prior to the close of business on the record date fixed for
     determination of stockholders entitled to receive such distribution shall
     be reduced by multiplying such Conversion Price by a fraction, the
     numerator of which is the Current Market Price on such record date less the
     fair market value (as determined in good faith by the board of directors,
     except in the case of a Spin-Off (as defined below)) of the portion of such
     evidences of indebtedness, shares of capital stock, other securities, cash
     and assets so distributed applicable to one share of Common Stock, and the
     denominator of which is the Current Market Price. Such adjustment shall be
     made successively whenever any such event shall occur.

          In respect of a dividend or other distribution of shares of Capital
     Stock of any class or series, or similar equity interests,

                                       6
<PAGE>

     of or relating to a subsidiary or other business unit of the Company (a
     "SPIN-OFF"), the adjustment to the Conversion Price under this subparagraph
     (iv) shall occur 20 trading days after the effective date of the Spin-Off.

          (v) ISSUANCE OF COMMON STOCK. In case the Company shall issue or sell
     any shares of Common Stock at a price per share less than the Current
     Market Price (other than any (i) such transaction as to which an adjustment
     is otherwise provided for in this Section 5, (ii) the issuance by the
     Company of Common Stock to pay interest pursuant to Section 3 hereof or in
     satisfaction of Affiliate Obligations or (iii) the issuance by the Company
     to directors, employees, consultants or advisors of the Company of shares
     of Common Stock, or grant of options or other rights to purchase or acquire
     Common Stock, at a price, or exercise price, as the case may be, no lower
     than the fair market value of the Common Stock (as reasonably determined by
     the independent directors of the Company in good faith as of the time of
     issuance or grant, as the case may be), so long as the aggregate number of
     shares of Common Stock that are so issued or with respect to which an
     option or other right is so granted under this clause (iii) does not exceed
     14,500,000 shares or (iv) the issuance by the Company of Common Stock
     pursuant to the NaviSite warrants in accordance with their terms as of the
     date hereof the Conversion Price in effect immediately prior to the close
     of business on the date immediately preceding such issuance or sale shall
     be reduced by multiplying such Conversion Price by a fraction, the
     numerator of which is the sum of the number of shares of Common Stock
     outstanding at the close of business on the date immediately preceding such
     issuance or sale (giving assumed effect to the conversion of all
     convertible securities outstanding on the date hereof) to and the number of
     shares of Common Stock that the aggregate price paid for the total number
     of shares of Common Stock so issued or sold on such date would purchase at
     such Current Market Price and the denominator of which is the sum of the
     number of shares of Common Stock outstanding at the close of business on
     the date immediately preceding such issuance or sale (giving assumed effect
     to the conversion of all convertible securities outstanding on the date
     hereof) and the number of additional shares of Common Stock so issued or
     sold. For purposes of this subparagraph (v), the issuance of rights,
     options or warrants to purchase Common Stock or securities convertible or
     exchangeable for Common Stock shall be deemed to be the issuance of the
     Common Stock into which such securities are exercisable at an aggregate
     price equal to the sum of the aggregate price paid for such securities and
     the minimum aggregate amount (if any) payable upon exercise or conversion
     of such options, rights, warrants or securities for Common Stock,

                                       7
<PAGE>

     and the date of issuance and sale for purposes hereof shall be the date
     upon which such options, rights or warrants were issued or amended. Such
     adjustment shall be made successively whenever any such event shall occur;
     provided that no adjustment shall be made upon exercise of any option,
     right or warrant. If an adjustment is made as the result of the issuance of
     an option, right, warrant or convertible security and such option, right,
     warrant or security expires unexercised or unconverted, the Conversion
     Price shall be readjusted to the price that would have been in effect if no
     such adjustment had been made.

          (vi) FUNDAMENTAL CHANGES. In case any transaction or event (including,
     without limitation, any merger, consolidation, combination,
     recapitalization, sale of assets, tender or exchange offer,
     reclassification, compulsory share exchange or liquidation) shall occur in
     which all or substantially all outstanding shares of Common Stock are
     converted into or exchanged or acquired for or constitute the right to
     receive stock, other securities, cash, property or assets (each, a
     "FUNDAMENTAL CHANGE"), the holder of this Note outstanding immediately
     prior to the occurrence of such Fundamental Change shall have the right
     upon any subsequent conversion to receive (but only out of legally
     available funds, to the extent required by applicable law) the kind and
     amount of stock, other securities, cash, property or assets that such
     holder would have received if such share had been converted immediately
     prior thereto.

     (b) (i) Subject to paragraph (b)(ii) below, each determination of the
Closing Price pursuant to clause (iv) of the definition of "Closing Price" shall
be made in good faith by the Company. Upon each determination of the fair market
value of the Common Stock by the Company hereunder, the Company shall promptly
give notice thereof to each Purchaser, setting forth in reasonable detail the
calculation of such fair market value and the method and basis of determination
thereof (the "Company Determination").

          (ii) If the Required Holders shall disagree with the Company
     Determination and shall by notice to the Company given within 10 days after
     the Company's notice of the Company Determination (an "Appraisal Notice")
     elect to dispute the Company Determination, such dispute shall be resolved
     as set forth in paragraph (b)(iii) below; provided that such procedure
     shall not apply to any determination of fair market value made pursuant to
     Section 5(a)(v)(ii).

                                       8
<PAGE>

          (iii) The Company shall within 10 days after an Appraisal Notice shall
     have been given pursuant to paragraph (b)(i) above engage an investment
     bank or other qualified appraisal firm reasonably acceptable to the
     Required Holders (the "APPRAISER") to make an independent determination of
     the fair market value of the Common Stock (the "APPRAISER DETERMINATION").
     The Appraiser Determination shall be final and binding on the Company and
     the Purchasers. If the Company Determination and the Appraiser
     Determination differ by an amount of 15% or less of the Company
     Determination, then the costs of conducting the appraisal shall be borne
     equally by the Company and the Purchasers; if the Company Determination is
     greater than the Appraiser Determination by more than 15% of the Company
     Determination, then the costs of conducting the appraisal shall be borne
     entirely by the Purchasers; and if the Appraiser Determination is greater
     than the Company Determination by more than 15% of the Company
     Determination, then the costs of conducting the appraisal shall be borne
     entirely by the Company; provided that in each case costs separately
     incurred by the Company and any Purchasers shall be separately borne by
     them.

     (c) Anything in paragraph (a) to the contrary notwithstanding, the Company
shall not be required to give effect to any adjustment in the Conversion Price
unless and until the net effect of one or more adjustments (each of which shall
be carried forward until counted toward adjustment), determined as above
provided, shall have resulted in a change of the Conversion Price by at least
1%, and when the cumulative net effect of more than one adjustment so determined
shall be to change the Conversion Price by at least 1%, such change in the
Conversion Price shall thereupon be given effect. In the event that, at any time
as a result of the provisions of this paragraph (b), the holder of this Note
upon subsequent conversion shall become entitled to receive any shares of
Capital Stock of the Company other than Common Stock, the number of such other
shares so receivable upon conversion of this Note shall thereafter be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions contained herein.

     (d) In any case in which paragraph (a) requires that an adjustment as a
result of any event is to become effective from and after a record date, the
Company may elect to defer until after the occurrence of such event (i) issuing
to the holder of this Note converted after such record date and before the
occurrence of such event the additional shares of Common Stock issuable upon
such conversion over and above the shares issuable on the basis of the
Conversion Price in effect immediately prior to

                                       9
<PAGE>

adjustment and (ii) paying to such holder any amount in cash in lieu of a
fractional share of Common Stock.

     (e) If the Company shall take a record of the holders of its Common Stock
for the purpose of entitling them to receive a dividend or other distribution,
and shall thereafter and before the distribution to stockholders thereof legally
abandon its plan to pay or deliver such dividend or distribution, then
thereafter no adjustment in the number of shares of Common Stock issuable upon
exercise of the right of conversion or in the Conversion Price then in effect
shall be required by reason of the taking of such record.

     (f) Upon any adjustment of the Conversion Price or the number of shares of
Common Stock issuable upon the Conversion of this Note, a certificate, signed by
(i) the Company's president and chief financial officer or (ii) any independent
firm of certified public accountants of recognized national standing the Company
selects at its own expense, setting forth in reasonable detail the events
requiring the adjustment and the method by which such adjustment was calculated,
shall be mailed to the Purchaser at the address set forth in Section 10.04 of
the Note Purchase Agreement hereof and shall specify the adjusted Conversion
Price and the number of shares of Common Stock issuable upon the Conversion of
the Note after giving effect to the adjustment.

     (g) The Company shall not, by amendment of its Certificate of Incorporation
or through any reorganization, recapitalization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company, but shall at all
times in good faith assist in the carrying out of all provisions of this Section
5 and in the taking of all such action as may be necessary or appropriate in
order to protect the rights of the Purchaser against impairment.

     (h) Except as otherwise provided herein, all sections of this Section 5 are
intended to operate independently of one another. If an event occurs that
requires the application of more than one section, all applicable sections shall
be given independent effect.

     6. Governing Laws.

     This Note shall be governed by, and construed in accordance with, the laws
of the State of New York in all respects, including all matters of construction,
validity and performance, without regard to the choice of law provisions
thereof.

    SECTION 2.  Guarantees by Guarantors.

    (a) Secured Guarantees.  Each Guarantor unconditionally guarantees the

maturity, upon acceleration or otherwise). If the Company fails to pay any
Secured Obligation punctually when due, each Guarantor agrees that it will
forthwith on demand pay the amount not so paid at the place and in the manner
specified in the relevant Secured Agreement.

    (b) Secured Guarantees Unconditional. The obligations of each Guarantor
under its Secured Guarantee shall be unconditional and absolute and, without
limiting the generality of the foregoing, shall not be released, discharged or
otherwise affected by:

    in respect of any obligation of the Company, any other Guarantor or any

    Secured Agreement;

    of the Company, any other Guarantor or any other Person or any of their

                                       6
<PAGE>

    respective subsidiaries, or any insolvency, bankruptcy, reorganization or
    other similar proceeding affecting the Company, any other Guarantor or any
    other Person or any of their assets or any resulting release or discharge of
    any obligation of the Company, any other Guarantor or any other Person under
    any Secured Agreement;

        (v)   the existence of any claim, set-off or other right that such
    Guarantor may have at any time against the Company, any other Guarantor, any
    Secured Party or any other Person, whether in connection with the Notes or
    any unrelated transactions, provided that nothing herein shall prevent the
    assertion of any such claim by separate suit or compulsory counterclaim;

        (vi) any invalidity or unenforceability relating to or against the
    Company, any other Guarantor or any other Person for any reason of any
    Secured Agreement, or any provision of applicable law or regulation
    purporting to prohibit the payment of any Secured Obligation by the Company,
    any other Guarantor or any other Person; or

        (vii) any other act or omission to act or delay of any kind by the
    Company, any other Guarantor, any other party to any Secured Agreement, any
    Secured Party or any other Person, or any other circumstance whatsoever that
    might, but for the provisions of this clause (vii), constitute a legal or
    equitable discharge of or defense to any obligation of any Guarantor
    hereunder.

    (c) Release of Secured Guarantees.  (i) All the Secured Guarantees will
be released when all the Release Conditions are satisfied. If at any time any
payment of a Secured Obligation is rescinded or must be otherwise restored or
returned upon the insolvency or receivership of the Company or otherwise, the
Secured Guarantees shall be reinstated with respect thereto as though such
payment had been due but not made at such time.

        (ii)  The Collateral Representative may release any Secured
     Guarantee with the prior written consent of the Required Holders.

    (d) Waiver by Guarantors. Each Guarantor irrevocably waives acceptance
hereof, presentment, demand, protest and any notice not provided for herein, as
well as any requirement that at any time any action be taken by any Person
against the Company, any other Guarantor or any other Person.

    (e) Subrogation.  A Guarantor that makes a payment with respect to a
Secured Obligation hereunder shall be subrogated to the rights of the payee


                                       7
<PAGE>

against the Company with respect to such payment; provided that no Guarantor
shall enforce any payment by way of subrogation against the Company, or by
reason of contribution against any other guarantor of such Secured Obligation,
until all the Release Conditions have been satisfied.

    (f) Stay of Acceleration.  If acceleration of the time for payment of any
Secured Obligation by the Company is stayed by reason of the insolvency or
receivership of the Company or otherwise, all Secured Obligations otherwise
subject to acceleration under the terms of any Secured Agreement shall
nonetheless be payable by the Guarantors hereunder forthwith on demand by the
Collateral Representative.

    (g) Continuing Guarantee.  Each Secured Guarantee is a continuing
guarantee, shall be binding on the relevant Guarantor and its successors and
assigns, and shall be enforceable by the Collateral Representative or the
Secured Parties. If all or part of any Secured Party's interest in any Secured
Obligation is assigned or otherwise transferred, the transferor's rights under
each Secured Guarantee, to the extent applicable to the obligation so
transferred, shall automatically be transferred with such obligation.

    (h) Limitation on Obligations of Subsidiary Guarantor.  The obligations
of each Subsidiary Guarantor under its Secured Guarantee shall be limited to an
aggregate amount equal to the largest amount that would not render such Secured
Guarantee subject to avoidance under Section 548 of the United States Bankruptcy
Code or any comparable provisions of applicable law.

    SECTION 3.  Grant of Transaction Liens.

    (a) The Company, in order to secure the Secured Obligations, and each
Guarantor listed on the signature pages hereof, in order to secure its Secured
Guarantee, grants to the Collateral Representative for the benefit of the

<PAGE>

        (v)    all General Intangibles (including any Equity Interests in other
    Persons that do not constitute Investment Property);

        (vi)   all Instruments;

        (vii)  all Inventory;

        (viii) all Investment Property;

        (ix)   all books and records (including customer lists, credit files,
    computer programs, printouts and other computer materials and records) of
    such Original Lien Grantor pertaining to any of its Collateral;

        (x)    such Original Lien Grantor's ownership interest in (1) its
    Collateral Accounts, (2) all Financial Assets credited to its Collateral
    Accounts from time to time and all Security Entitlements in respect thereof,
    (3) all cash held in its Collateral Accounts from time to time and (4) all
    other money in the possession of the Collateral Representative; and

        (xi)   all Proceeds of the Collateral described in the foregoing
    clauses (i) through (x).

    (b) With respect to each right to payment or performance included in the
Collateral from time to time, the Transaction Lien granted therein includes a
continuing security interest in (i) any Supporting Obligation that supports such
payment or performance and (ii) any Lien that (x) secures such right to payment
or performance or (y) secures any such Supporting Obligation.

    (c) The Transaction Liens are granted as security only and shall not subject
the Collateral Representative or any other Secured Party to, or transfer or in
any way affect or modify, any obligation or liability of any Lien Grantor with
respect to any of the Collateral or any transaction in connection therewith.

    SECTION 4.  General Representations and Warranties.  Each Original Lien
Grantor represents and warrants that:

    (a) Such Lien Grantor is a corporation1 duly organized, validly existing
and in good standing under the laws of the jurisdiction identified as its
jurisdiction of organization in its Perfection Certificate.

-------------
    1  Modify as needed if any Original Lien Grantor is not a corporation.


                                       9
<PAGE>

    (b) Schedule 1 lists all Equity Interests in Subsidiaries and Affiliates
owned by such Lien Grantor as of the Effective Date. Such Lien Grantor holds all
such Equity Interests directly (i.e., not through a Subsidiary, a Securities
Intermediary or any other Person).

    (c) Except as set forth on the Perfection Certificate of such Lien Grantor,
all Pledged Equity Interests owned by such Lien Grantor are owned by it free and
clear of any Lien other than (i) the Transaction Liens and (ii) any tax liens,
judgment liens and other Permitted Liens. All shares of capital stock included
in such Pledged Equity Interests (including shares of capital stock in respect
of which such Lien Grantor owns a Security Entitlement) have been duly
authorized and validly issued and are fully paid and non-assessable. None of
such Pledged Equity Interests is subject to any option to purchase or similar
right of any Person. Such Lien Grantor is not and will not become a party to or
otherwise bound by any agreement (except the Note Documents) which restricts in
any manner the rights of any present or future holder of any Pledged Equity
Interest with respect thereto.

    (d) Except as set forth on the Perfection Certificate of such Lien Grantor,
such Lien Grantor has good and marketable title to all its Collateral (subject
to exceptions that are, in the aggregate, not material), free and clear of any
Lien other than Permitted Liens.

    (e) Such Lien Grantor has not performed any acts that might prevent the
Collateral Representative from enforcing any of the provisions of the Security
Documents or that would limit the Collateral Representative in any such
enforcement. No financing statement, security agreement, mortgage or similar or
equivalent document or instrument covering all or part of the Collateral owned
by such Lien Grantor is on file or of record in any jurisdiction in which such
filing or recording would be effective to perfect or record a Lien on such
Collateral, except financing statements, mortgages or other similar or
equivalent documents with respect to Permitted Liens. After the Effective Date,
no Collateral owned by such Lien Grantor will be in the possession or under the
Control of any other Person having a claim thereto or security interest therein,
other than a Permitted Lien.

    (f) The Transaction Liens on all Collateral owned by such Lien Grantor
(i) have been validly created, (ii) will attach to each item of such Collateral
on the Effective Date (or, if such Lien Grantor first obtains rights thereto on
a later date, on such later date) and (iii) when so attached, will secure all
the Secured Obligations or such Lien Grantor's Secured Guarantee, as the case
may be.

    (g) Such Lien Grantor has delivered a Perfection Certificate to the
Collateral Representative.  The information set forth therein is correct and


                                      10
<PAGE>

complete as of the Effective Date. Within 60 days after the Effective Date, such
Lien Grantor will furnish to the Collateral Representative a file search report
from each UCC filing office listed in its Perfection Certificate, showing the
filing made at such filing office to perfect the Transaction Liens on its
Collateral.

    (h) When UCC financing statements describing the Collateral as set forth in
Schedule 1 to such Lien Grantor's Perfection Certificate have been filed in the
offices specified in such Perfection Certificate, the Transaction Liens will
constitute perfected security interests in the Collateral owned by such Lien
Grantor to the extent that a security interest therein may be perfected by
filing pursuant to the UCC, prior to all Liens and rights of others therein
except Permitted Liens.

    (i) Such Lien Grantor has taken, and will continue to take, all actions
necessary under the UCC to perfect its interest in (i) any Accounts or Chattel
Paper purchased or otherwise acquired by it, as against its assignors and
creditors of its assignors and (ii) any Payment Intangibles or promissory notes
purchased or otherwise acquired by it, as against its assignors and creditors of
its assignors.

    (j) Such Lien Grantor's Collateral is insured as required by the Note
Purchase Agreement.

    (k) All of such Lien Grantor's Inventory has or will have been produced
in compliance, in all material respects, with the applicable requirements of the
Fair Labor Standards Act, as amended.

    SECTION 5.  Further Assurances; General Covenants.  Each Lien Grantor
covenants as follows:

    (a) Such Lien Grantor will, from time to time, at the Company's expense,
execute, deliver, file and record any statement, assignment, instrument,
document, agreement or other paper and take any other action (including any
intellectual property filing and any filing of financing or continuation
statements under the UCC) that from time to time may be necessary or desirable,
or that the Collateral Representative may request, in order to:

        (i)   create, preserve, perfect, confirm or validate the Transaction
    Liens on such Lien Grantor's Collateral;

        (ii)  enable the Collateral Representative and the other Secured
    Parties to obtain the full benefits of the Security Documents; or


                                      11
<PAGE>

        (iii) enable the Collateral Representative to exercise and enforce any
    of its rights, powers and remedies with respect to any of such Lien
    Grantor's Collateral.

To the extent permitted by applicable law, such Lien Grantor authorizes the
Collateral Representative to execute and file such financing statements or
continuation statements without such Lien Grantor's signature appearing thereon.
Such Lien Grantor agrees that a carbon, photographic, photostatic or other
reproduction of this Agreement or of a financing statement is sufficient as a
financing statement. Such Lien Grantor constitutes the Collateral Representative
its attorney-in-fact to execute and file all intellectual property filings and
other filings required or so requested for the foregoing purposes, all acts of
such attorney being hereby ratified and confirmed; and such power, being coupled
with an interest, shall be irrevocable until all the Transaction Liens granted
by such Lien Grantor terminate pursuant to Section 14. The Company will pay the
costs of, or incidental to, any intellectual property filings and any recording
or filing of any financing or continuation statements or other documents
recorded or filed pursuant hereto in accordance with clause (ii) of the second
sentence of Section 9.01 of the Note Purchase Agreement.

    (b) Such Lien Grantor will not (i) change its name or corporate structure,
(ii) change its location (determined as provided in UCC Section 9-307) or (iii)
become bound, as provided in UCC Section 9-203(d) or otherwise, by a security
agreement entered into by another Person, unless it shall have given the
Collateral Representative prior notice thereof.

    (c) At least 30 days before it takes any action contemplated by Section
5(b), such Lien Grantor will, at the Company's expense and at the request of the
Purchasers, cause to be delivered to the Collateral Representative an Opinion of
Counsel, in form and substance satisfactory to the Collateral Representative, to
the effect that (i) all financing statements and amendments or supplements
thereto, continuation statements and other documents required to be filed or
recorded in order to perfect and protect the Transaction Liens against all
creditors of and purchasers from such Lien Grantor after it takes such action
(except any continuation statements specified in such Opinion of Counsel that
are to be filed more than six months after the date thereof) have been filed or
recorded in each office necessary for such purpose, (ii) all fees and taxes, if
any, payable in connection with such filings or recordations have been paid in
full and (iii) except as otherwise agreed by the Required Holders, such action
will not adversely affect the perfection or priority of the Transaction Lien on
any Collateral to be owned by such Lien Grantor after it takes such action or
the accuracy of such Lien Grantor's representations and warranties herein
relating to such Collateral.


                                      12

    (d) If any Collateral is located on premises leased by a Lien Grantor as
lessee, such Lien Grantor shall, within 60 days of the date hereof in the case
of leases in existence on the date hereof, and substantially simultaneously with
the execution and delivery of such lease, in the case of leases hereafter
entered into, use its reasonable efforts to secure from the landlord a waiver of
contractual and statutory landlord's liens, an agreement to permit access to and
removal of Collateral and other customary matters, all pursuant to an instrument
in form and substance satisfactory to the Collateral Representative.

    (e) Such Lien Grantor will not sell, lease, exchange, assign or otherwise
dispose of, or grant any option with respect to, any of its Collateral; provided
that such Lien Grantor may do any of the foregoing unless (i) doing so would
violate a covenant in the Note Purchase Agreement or (ii) an Event of Default
shall have occurred and be continuing and the Collateral Representative shall
have notified such Lien Grantor that its right to do so is terminated, suspended
or otherwise limited. Concurrently with any sale, lease or other disposition
(except a sale or disposition to another Lien Grantor or a lease) permitted by
the foregoing proviso, the Transaction Liens on the assets sold or disposed of
(but not in any Proceeds arising from such sale or disposition) will cease
immediately without any action by the Collateral Representative or any other
Secured Party. The Collateral Representative will, at the Company's expense,
execute and deliver to the relevant Lien Grantor such documents as such Lien
Grantor shall reasonably request to evidence the fact that any asset so sold or
disposed of is no longer subject to a Transaction Lien.

    (f) Such Lien Grantor will, promptly upon request, provide to the
Collateral Representative all information and evidence concerning such Lien
Grantor's Collateral that the Collateral Representative may reasonably request
from time to time to enable it to enforce the provisions of the Security
Documents.

    SECTION 6.  Investment Property.  Each Lien Grantor represents, warrants
and covenants as follows:

    (a) Certificated Securities.  On the Effective Date (in the case of an
Original Lien Grantor) or the date on which it signs and delivers its first
Security Agreement Supplement (in the case of any other Lien Grantor), such Lien
Grantor will deliver to the Collateral Representative as Collateral hereunder
all certificates representing Pledged Certificated Securities then owned by such
Lien Grantor. Thereafter, whenever such Lien Grantor acquires any other
certificate representing a Pledged Certificated Security, such Lien Grantor will
immediately deliver such certificate to the Collateral Representative as
Collateral hereunder.


                                      13
<PAGE>

    (b) Uncertificated Securities.  On the Effective Date (in the case of an
Original Lien Grantor) or the date on which it signs and delivers its first
Security Agreement Supplement (in the case of any other Lien Grantor), such Lien
Grantor will enter into (and cause the relevant issuer to enter into) an Issuer
Control Agreement in respect of each Pledged Uncertificated Security then owned
by such Lien Grantor and deliver such Issuer Control Agreement to the Collateral
Representative (which shall enter into the same). Thereafter, whenever such Lien
Grantor acquires any other Pledged Uncertificated Security, such Lien Grantor
will enter into (and cause the relevant issuer to enter into) an Issuer Control
Agreement in respect of such Pledged Uncertificated Security and deliver such
Issuer Control Agreement to the Collateral Representative (which shall enter
into the same).

    (c) Delivery of Pledged Certificates.  All Pledged Certificates, when
delivered to the Collateral Representative, will be in suitable form for
transfer by delivery, or accompanied by duly executed instruments of transfer or
assignment in blank, with signatures appropriately guaranteed, all in form and
substance satisfactory to the Collateral Representative.

    SECTION 7. Collateral Accounts. (a) If and when required for purposes
hereof, the Collateral Representative will establish with respect to each Lien
Grantor an account (its "COLLATERAL ACCOUNT"), in the name and under the
exclusive control of the Collateral Representative, into which all amounts owned
by such Lien Grantor that are to be deposited therein pursuant to the Note
Documents shall be deposited from time to time. Each Cash Collateral Account
will be operated as provided in this Section.

    (b) The Collateral Representative shall deposit the following amounts,
as and when received by it, in the Collateral Account of the applicable Lien
Grantor:

        (i)   each amount required by the Note Documents to be deposited
    therein, including, without limitation, all proceeds specified in Section
    5.04(d) of the Note Purchase Agreement; and

        (ii) each amount realized or otherwise received by the Collateral
    Representative with respect to assets of such Lien Grantor upon any exercise
    of remedies pursuant to any Security Document.

    (c) Unless (x) an Event of Default shall have occurred and be continuing
and the Required Holders shall have instructed the Collateral Representative
to stop withdrawing amounts from the Collateral Account pursuant to this
subsection or (y) the maturity of the Notes shall have been accelerated
pursuant to Article 7


                                      14
<PAGE>

of the Note Purchase Agreement, the Collateral Representative shall withdraw
amounts deposited in the Collateral Account in accordance with Section 5.04(d)
of the Note Purchase Agreement and apply them to pay, or reimburse the Company
and its Subsidiaries for paying, the cost of repairing, restoring or replacing
the affected property to the extent that the Company has certified, no less than
5 Business Days prior to the date of such withdrawal, that (i) it and its
Subsidiaries intend to apply all or any portion of such amounts to pay the cost
of repairing, restoring or replacing the affected property and (ii) if such
property is to be replaced, the property acquired to replace it will be included
in the Collateral at least to the extent that the property to be replaced was
included therein;

    (d) Funds held in any Collateral Account may, until withdrawn, be
invested and reinvested in such Temporary Cash Investments as the relevant Lien
Grantor shall request from time to time; provided that, if an Event of Default
shall have occurred and be continuing, the Collateral Representative may select
such Temporary Cash Investments.

    (e) If an Event of Default shall have occurred and be continuing, the
Collateral Representative may withdraw any amounts held therein and apply such
amounts as provided in Section 9.

    SECTION 8. Remedies upon Event of Default. (a) If an Event of Default shall
have occurred and be continuing, the Collateral Representative may exercise (or
cause its sub-agents to exercise) any or all of the remedies available to it (or
to such sub-agents) under the Security Documents.

    (b) Without limiting the generality of the foregoing, if an Event of
Default shall have occurred and be continuing, the Collateral Representative may
exercise on behalf of the Secured Parties all the rights of a secured party
under the UCC (whether or not in effect in the jurisdiction where such rights
are exercised) with respect to any Collateral and, in addition, the Collateral
Representative may, without being required to give any notice, except as herein
provided or as may be required by mandatory provisions of law, withdraw all cash
held in the Collateral Accounts and apply such cash as provided in Section 9
and, if there shall be no such cash or if such cash shall be insufficient to pay
all the Secured Obligations in full, sell, lease, license or otherwise dispose
of the Collateral or any part thereof. Notice of any such sale or other
disposition shall be given to the relevant Lien Grantor(s) as required by
Section 11. The foregoing provisions of this subsection shall apply to Real
Property Collateral only to the extent permitted by applicable law and the
provisions of any applicable Mortgage or other document.

    (c) Without limiting the generality of the foregoing, if an Event of
Default shall have occurred and be continuing:


                                      15
<PAGE>

        (i) the Collateral Representative may license or sublicense, whether
    general, special or otherwise, and whether on an exclusive or non-exclusive
    basis, any Pledged intellectual property (including any Pledged Recordable
    Intellectual Property) throughout the world for such term or terms, on such
    conditions and in such manner as the Collateral Representative shall in its
    sole discretion determine; provided that such licenses or sublicenses do not
    conflict with any existing license made available to the Collateral
    Representative;

        (ii) the Collateral Representative may (without assuming any obligation
    or liability thereunder), at any time and from time to time, in its sole and
    reasonable discretion, enforce (and shall have the exclusive right to
    enforce) against any licensee or sublicensee all rights and remedies of any
    Lien Grantor in, to and under any of its Pledged intellectual property and
    take or refrain from taking any action under any thereof, and each Lien
    Grantor releases the Collateral Representative and each other Secured Party
    from liability for, and agrees to hold the Collateral Representative and
    each other Secured Party free and harmless from and against any claims and
    expenses arising out of, any lawful action so taken or omitted to be taken
    with respect thereto, except for claims and expenses arising from the
    Collateral Representative's or such Secured Party's gross negligence or
    willful misconduct; and

        (iii) upon request by the Collateral Representative (which shall not be
    construed as implying any limitation on its rights or powers), each Lien
    Grantor will execute and deliver to the Collateral Representative a power of
    attorney, in form and substance satisfactory to the Collateral
    Representative, for the implementation of any sale, lease, license or other
    disposition of any of such Lien Grantor's Pledged intellectual property or
    any action related thereto. In connection with any such disposition, but
    subject to any confidentiality restrictions imposed on such Lien Grantor in
    any license or similar agreement, such Lien Grantor will supply to the
    Collateral Representative its know-how and expertise relating to the
    relevant intellectual property or the products or services made or rendered
    in connection with such intellectual property, and its customer lists and
    other records relating to such intellectual property and to the distribution
    of said products or services.

    SECTION 9. Application of Proceeds. (a) If an Event of Default shall have
occurred and be continuing, the Collateral Representative may apply (i) any cash
held in the Collateral Accounts and (ii) the proceeds of any sale or other
disposition of all or any part of the Collateral, in the following order of
priorities:


                                      16
<PAGE>

        first, to pay the expenses of such sale or other disposition, including
    reasonable compensation to agents of and counsel for the Collateral
    Representative, and all expenses, liabilities and advances incurred or made
    by the Collateral Representative in connection with the Security Documents;

        second, to pay the unpaid principal of the Secured Obligations ratably
    until payment in full of the principal of all Secured Obligations shall have
    been made;

        third, to pay ratably all interest (including Post-Petition Interest) on
    the Secured Obligations until payment in full of all such interest shall
    have been made;

        fourth, to pay all other Secured Obligations ratably until payment in
    full of all such other Secured Obligations shall have been made; and

        finally, to pay to the relevant Lien Grantor, or as a court of competent
    jurisdiction may direct, any surplus then remaining from the proceeds of
    the Collateral owned by it;

provided that Collateral owned by a Guarantor and any proceeds thereof shall be
applied pursuant to the foregoing clauses first, second, third and fourth only
to the extent permitted by the limitation in Section 2(h). The Collateral
Representative may make such distributions hereunder in cash or in kind or, on a
ratable basis, in any combination thereof.

    (b) In making the payments and allocations required by this Section, the
Collateral Representative may rely upon information supplied to it by the
Secured Parties. All distributions made by the Collateral Representative
pursuant to this Section shall be final (except in the event of manifest error)
and the Collateral Representative shall have no duty to inquire as to the
application by any Secured Party of any amount distributed to it.

    SECTION 10.  Fees and Expenses; Indemnification.  (a) The Company will
forthwith upon demand pay to the Collateral Representative:

        (i) the amount of any taxes that the Collateral Representative may have
    been required to pay by reason of the Transaction Liens or to free any
    Collateral from any other Lien thereon;

        (ii)  the amount of any and all reasonable out-of-pocket expenses,
    including transfer taxes and reasonable fees and expenses of counsel and


                                      17
<PAGE>

    other experts, that the Collateral Representative may incur in connection
    with (x) the administration or enforcement of the Security Documents,
    including such expenses as are incurred to preserve the value of the
    Collateral or the validity, perfection, rank or value of any Transaction
    Lien, (y) the collection, sale or other disposition of any Collateral or (z)
    the exercise by the Collateral Representative of any of its rights or powers
    under the Security Documents; and

        (iii) the amount required to indemnify the Collateral Representative
    for, or hold it harmless and defend it against, any loss, liability or
    expense (including the reasonable fees and expenses of its counsel and any
    experts or sub-agents appointed by it hereunder) incurred or suffered by the
    Collateral Representative in connection with the Security Documents, except
    to the extent that such loss, liability or expense arises from the
    Collateral Representative's gross negligence or willful misconduct or a
    breach of any duty that the Collateral Representative has under this
    Agreement (after giving effect to Sections 12 and 13).

Any such amount not paid to the Collateral Representative in accordance with the
Security Documents will bear interest for each day thereafter until paid at a
rate of 14% per annum.

    (b) If any transfer tax, documentary stamp tax or other tax is payable in
connection with any transfer or other transaction provided for in the Security
Documents, the Company will pay such tax and provide any required tax stamps to
the Collateral Representative or as otherwise required by law.

    SECTION 11. Authority to Administer Collateral. Each Lien Grantor
irrevocably appoints the Collateral Representative its true and lawful attorney,
with full power of substitution, in the name of such Lien Grantor, any Secured
Party or otherwise, for the sole use and benefit of the Secured Parties, but at
the Company's expense, to the extent permitted by law to exercise, at any time
and from time to time while an Event of Default shall have occurred and be
continuing, all or any of the following powers with respect to all or any of
such Lien Grantor's Collateral:

        (a) to demand, sue for, collect, receive and give acquittance for
    any and all monies due or to become due upon or by virtue thereof,

        (b) to settle, compromise, compound, prosecute or defend any
    action or proceeding with respect thereto,


                                      18
<PAGE>

        (c) to sell, lease, license or otherwise dispose of the same or the
    proceeds or avails thereof, as fully and effectually as if the Collateral
    Representative were the absolute owner thereof, and

        (d) to extend the time of payment of any or all thereof and to
    make any allowance or other adjustment with reference thereto;

provided that, except in the case of Collateral that is perishable or threatens
to decline speedily in value or is of a type customarily sold on a recognized
market, the Collateral Representative will give the relevant Lien Grantor at
least ten days' prior written notice of the time and place of any public sale
thereof or the time after which any private sale or other intended disposition
thereof will be made. Any such notice shall (i) contain the information
specified in UCC Section 9-613, (ii) be Authenticated and (iii) be sent to the
parties required to be notified pursuant to UCC Section 9-611(c); provided that,
if the Collateral Representative fails to comply with this sentence in any
respect, its liability for such failure shall be limited to the liability (if
any) imposed on it as a matter of law under the UCC.

    SECTION 12. Limitation on Duty in Respect of Collateral. Beyond the exercise
of reasonable care in the custody and preservation thereof, the Collateral
Representative will have no duty as to any Collateral in its possession or
control or in the possession or control of any sub-agent or bailee or any income
therefrom or as to the preservation of rights against prior parties or any other
rights pertaining thereto. The Collateral Representative will be deemed to have
exercised reasonable care in the custody and preservation of the Collateral in
its possession or control if such Collateral is accorded treatment substantially
equal to that which it accords its own property, and will not be liable or
responsible for any loss or damage to any Collateral, or for any diminution in
the value thereof, by reason of any act or omission of any sub-agent or bailee
selected by the Collateral Representative in good faith, except to the extent
that such liability arises from the Collateral Representative's gross negligence
or willful misconduct.

    SECTION 13. General Provisions Concerning the Collateral Representative. (a)
Authority. The Collateral Representative is authorized to take such actions and
to exercise such powers as are delegated to the Collateral Representative by the
terms of the Security Documents, together with such actions and powers as are
reasonably incidental thereto.

    (b) Rights and Powers as a Secured Party. The Collateral Representative
shall, in its capacity as a Secured Party, have the same rights and powers as
any other Secured Party and may exercise the same as though it were not the
Collateral Representative.


                                      19
<PAGE>

    (c) Limited Duties and Responsibilities.  The Collateral Representative
shall not have any duties or obligations under the Security Documents except
those expressly set forth therein. Without limiting the generality of the
foregoing, (a) the Collateral Representative shall not be subject to any
fiduciary or other implied duties, regardless of whether an Event of Default has
occurred and is continuing and (b) the Collateral Representative shall not have
any duty to take any discretionary action or exercise any discretionary powers,
except discretionary rights and powers expressly contemplated by the Security
Documents that the Collateral Representative is required in writing to exercise
by the Required Holders. The Collateral Representative shall not be liable for
any action taken or not taken by it with the consent or at the request of the
Required Holders or in the absence of its own gross negligence or willful
misconduct. The Collateral Representative shall not be responsible for the
existence, genuineness or value of any Collateral or for the validity,
perfection, priority or enforceability of any Transaction Lien, whether impaired
by operation of law or by reason of any action or omission to act on its part
under the Security Documents. The Collateral Representative shall be deemed not
to have knowledge of any Event of Default unless and until written notice
thereof is given to the Collateral Representative by the Company or a Secured
Party, and the Collateral Representative shall not be responsible for or have
any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with any Security Document, (ii) the
contents of any certificate, report or other document delivered thereunder or in
connection therewith, (iii) the performance or observance of any of the
covenants, agreements or other terms or conditions set forth in any Security
Document, (iv) the validity, enforceability, effectiveness or genuineness of any
Security Document or any other agreement, instrument or document, or (v) the
satisfaction of any condition set forth in any Security Document.

    (d) Authority to Rely on Certain Writings, Statements and Advice.  The
Collateral Representative shall be entitled to rely on, and shall not incur any
liability for relying on, any notice, request, certificate, consent, statement,
instrument, document or other writing believed by it to be genuine and to have
been signed or sent by the proper Person. The Collateral Representative also may
rely on any statement made to it orally or by telephone and believed by it to be
made by the proper Person, and shall not incur any liability for relying
thereon. The Collateral Representative may consult with legal counsel (who may
be counsel for the Company), independent accountants and other experts selected
by it, and shall not be liable for any action taken or not taken by it in
accordance with the advice of any such counsel, accountant or expert.

    (e) Sub-Agents and Related Parties.  The Collateral Representative may
perform any of its duties and exercise any of its rights and powers through
one or


                                      20
<PAGE>

more sub-agents appointed by it. The Collateral Representative and any such sub-
agent may perform any of its duties and exercise any of its rights and powers
through its Related Parties. The exculpatory provisions of Section 12 and this
Section shall apply to any such sub-agent and to the Related Parties of the
Collateral Representative and any such sub-agent.

    (f) The Collateral Representative may refuse to act on any notice, consent,
direction or instruction from any Secured Parties or any agent, trustee or
similar representative thereof that, in the Collateral Representative's opinion,
(i) is contrary to law or the provisions of any Security Document or (ii) may
expose the Collateral Representative to liability (unless the Collateral
Representative shall have been indemnified, to its reasonable satisfaction, for
such liability by the Secured Parties that gave such notice, consent, direction
or instruction).

    (g) Resignation; Successor Collateral Representative.  Subject to the
appointment and acceptance of a successor Collateral Representative as provided
in this subsection, the Collateral Representative may resign at any time by
notifying the Holders and the Company. Upon any such resignation, the Required
Holders shall have the right, in consultation with the Company, to appoint a
successor Collateral Representative. If no successor shall have been so
appointed by the Required Holders and shall have accepted such appointment
within 30 days after the retiring Collateral Representative gives notice of its
resignation, then the retiring Collateral Representative may, on behalf of the
Secured Parties, appoint a successor Collateral Representative. Upon acceptance
of its appointment as Collateral Representative hereunder by a successor, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Collateral Representative hereunder, and
the retiring Collateral Representative shall be discharged from its duties and
obligations hereunder. After the Collateral Representative's resignation
hereunder, the provisions of this Section and Section 12 shall continue in
effect for the benefit of such retiring Collateral Representative, its
sub-agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while the retiring Collateral
Representative was acting as Collateral Representative.

    SECTION 14.  Termination of Transaction Liens; Release of Collateral.  (a)
The Transaction Liens granted by each Guarantor shall terminate when its Secured
Guarantee is released pursuant to Section 2(c).

    (b) The Transaction Liens granted by the Company shall terminate when all
the Release Conditions are satisfied.

    (c) At any time before the Transaction Liens granted by the Company
terminate, the Collateral Representative may, at the written request of the


                                      21
<PAGE>

Company, release any or all of the Collateral with the prior written consent of
the Required Holders.

    (d) Upon any termination of a Transaction Lien or release of Collateral,
the Collateral Representative will, at the expense of the relevant Lien Grantor,
execute and deliver to such Lien Grantor such documents as such Lien Grantor
shall reasonably request to evidence the termination of such Transaction Lien or
the release of such Collateral, as the case may be.

    SECTION 15. Additional Guarantors and Lien Grantors. Any Subsidiary may
become a party hereto by signing and delivering to the Collateral Representative
a Security Agreement Supplement, whereupon such Subsidiary shall become a
"Guarantor" and a "Lien Grantor" as defined herein.

    SECTION 16. Notices. Each notice, request or other communication given to
any party hereunder shall be in writing (which term includes facsimile or other
electronic transmission) and shall be effective (i) when delivered to such party

    Purchase Agreement.

Any party may change its address and/or facsimile number for purposes of this
Section by giving notice of such change to the Collateral Representative and the
Lien Grantors in the manner specified above.

    SECTION 17. No Implied Waivers; Remedies Not Exclusive. No failure by the
Collateral Representative or any Secured Party to exercise, and no delay in
exercising and no course of dealing with respect to, any right or remedy under
any Security Document shall operate as a waiver thereof; nor shall any single or
partial exercise by the Collateral Representative or any Secured Party of any
right or remedy under any Note Document preclude any other or further exercise
thereof or the exercise of any other right or remedy. The rights and remedies
specified in the Note Documents are cumulative and are not exclusive of any
other rights or remedies provided by law.

    SECTION 18. Successors and Assigns. This Agreement is for the benefit of the
Collateral Representative and the Secured Parties. If all or any part of any
Secured Party's interest in any Secured Obligation is assigned or otherwise
transferred, the transferor's rights hereunder, to the extent applicable to the
obligation so transferred, shall be automatically transferred with such
obligation. This Agreement shall be binding on the Lien Grantors and their
respective successors and assigns.

hereof may be waived, amended, modified or terminated except pursuant to an

with and governed by the laws of the State of New York, except as otherwise
required by mandatory provisions of law and except to the extent that remedies
provided by the laws of any jurisdiction other than the State of New York are
governed by the laws of such jurisdiction.

    SECTION 21. Waiver of Jury Trial. EACH PARTY HERETO WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN
ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO ANY
SECURITY DOCUMENT OR ANY TRANSACTION CONTEMPLATED THEREBY (WHETHER BASED ON
CONTRACT, TORT


                                      23
<PAGE>

OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE,
THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION.

    SECTION 22. Severability. If any provision of any Security Document is
invalid or unenforceable in any jurisdiction, then, to the fullest extent
permitted by law, (i) the other provisions of the Security Documents shall
remain in full force and effect in such jurisdiction and shall be liberally
construed in favor of the Collateral Representative and the Secured Parties in
order to carry out the intentions of the parties thereto as nearly as may be
possible and (ii) the invalidity or unenforceability of such provision in such
jurisdiction shall not affect the validity or enforceability thereof in any
other jurisdiction.

II.  Registration Rights.

     2.1  Required Registrations.

     (a)  At any time, a Stockholder or Stockholders may request, in writing,
that the Company effect the registration on Form S-1 or Form S-3 (or successor
forms) of Registrable Shares owned by such Stockholder or Stockholders having an
aggregate value of at least $2,500,000 (based on the then current public market
price).

     (b)  Upon receipt of any request for registration pursuant to this Section
2.1, the Company shall promptly give written notice of such proposed
registration to all other Stockholders. Such Stockholders shall have the right,
by giving written notice to the Company within 15 days after the Company
provides its notice, to elect to have included in such registration such of
their Registrable Shares as such Stockholders may request in such notice of
election, subject in the case of an underwritten offering to the approval of the
managing underwriter as provided in Section 2.1(c) below. Thereupon, the Company
shall, as expeditiously as possible, use its best efforts to effect the
registration on an appropriate registration form of all Registrable Shares which
the Company has been requested to so register.

     (c)  If the Initiating Holders intend to distribute the Registrable Shares
covered by their request by means of an underwriting, they shall so advise the
Company as a part of their request made pursuant to Section 2.1(a) and the
Company shall include such information in its written notice referred to in
Section 2.1(b). The right of any other Stockholder to include its Registrable
Shares in such registration pursuant to Section 2.1(a) shall be conditioned upon
such other Stockholder's participation in such underwriting on the terms set
forth herein. If the managing underwriter determines that the marketing factors
require a limitation of the number of shares to be underwritten, the number of
Registrable Shares to be included in a Registration Statement filed pursuant to
this Section 2.1 shall be reduced pro rata among the requesting Stockholders
based on the quotient of (i) the total Registrable Shares to be included in the
Registration Statement, divided by (ii) the total number of Registrable Shares
that requested registration.

     (d)  The Initiating Holders shall have the right to select the managing
underwriter(s) for any underwritten offering requested pursuant to Section
2.1(a), subject to the approval of the Company, which approval will not be
unreasonably withheld.

                                       3
<PAGE>

     (e)  The Company shall not be required to effect more than five
registrations initiated by CMGI pursuant to Section 2.1(a) or more than ten
registrations initiated by CFS pursuant to Section 2.1(a).  In addition, the
Company shall not be required to effect any registration within 90 days after
the effective date of any other Registration Statement of the Company relating
to an underwritten offering. For purposes of this Section 2.1(e), a Registration
Statement shall not be counted until such time as such Registration Statement
has been declared effective by the Commission, unless the Initiating Holders
withdraw their request for such registration (other than as a result of
information concerning the business or financial condition of the Company which
is made known to the Stockholders after the date on which such registration was
requested) and elect not to pay the Registration Expenses therefor pursuant to
Section 2.4.

     (f)  If at the time of any request to register Registrable Shares by the
Initiating Holders pursuant to this Section 2.1, the Company is engaged or has
plans to engage in a registered public offering or is engaged in any other
activity which, in the good faith determination of the Company's board of
directors, would be adversely affected by the requested registration or if
financial statements required for the requested registration are not then
available, then the Company may at its option direct that such request be
delayed for a period not in excess of 90 days from the date of such request,
such right to delay a request to be exercised by the Company not more than once
in any 12-month period.

     2.2  Incidental Registration.

     (a)  Whenever the Company proposes to file a Registration Statement (other
than a Registration Statement filed pursuant to Section 2.1) at any time and
from time to time, it will, prior to such filing, give written notice to all
Stockholders of its intention to do so; provided, that no such notice need be
given if no Registrable Shares are to be included therein as a result of a
determination of the managing underwriter pursuant to Section 2.2(b). Upon the
written request of a Stockholder or Stockholders given within 20 days after the
Company provides such notice (which request shall state the intended method of
disposition of such Registrable Shares), the Company shall use its best efforts
to cause all Registrable Shares which the Company has been requested by such
Stockholder or Stockholders to register to be registered under the Securities
Act to the extent necessary to permit their sale or other disposition in
accordance with the intended methods of distribution specified in the request of
such Stockholder or Stockholders; provided, that the Company shall have the
right to postpone or withdraw any registration effected pursuant to this Section
2.2 without obligation to any Stockholder.

     (b)  If the registration for which the Company gives notice pursuant to
Section 2.2(a) involves an underwriting, the Company shall so advise the
Stockholders as a part of the written notice given pursuant to Section 2.2(a).
In such event, the right of any Stockholder to include its Registrable Shares in
such

                                       4
<PAGE>

registration pursuant to Section 2.2 shall be conditioned upon such
Stockholder's participation in such underwriting on the terms set forth herein.
All Stockholders proposing to distribute their securities through such
underwriting shall enter into an underwriting agreement in customary form with
the underwriter or underwriters selected for the underwriting by the Company.
Notwithstanding any other provision of this Agreement, if the Company and the
managing underwriter(s) determine in good faith that marketing factors require a
limitation of the number of shares to be underwritten, then the Company and the
managing underwriter(s) may exclude shares from the registration and the
underwriting, and the number of shares that may be included in the registration
and the underwriting shall be allocated, first to the Company or the Company
stockholder(s) for which the registration was initiated, and second to each of
the Stockholders requesting inclusion of their Registrable Shares in such
registration and each of the other holders of piggyback registration rights on a
parity with those Stockholders on a pro rata basis based on the total number of
Registrable Shares and other securities requested for inclusion in such
registration by each such Stockholder or other holder. If any holder of
Registrable Shares or any other Company stockholder requesting inclusions of
securities in the registration disapproves of the terms of any such
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, and any Registrable Shares or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration.

     (c)  Notwithstanding the foregoing, the Company shall not be required,
pursuant to this Section 2.2, to include any Registrable Shares in a
Registration Statement if such Registrable Shares can then be sold pursuant to
Rule 144(k) under the Securities Act and represent less than 1% of the then
outstanding shares of Common Stock.

     2.3  Registration Procedures.

     (a)  If and whenever the Company is required by the provisions of this
Agreement to use its best efforts to effect the registration of any Registrable
Shares under the Securities Act, the Company shall:

          (i) file with the Commission a Registration Statement with respect to
     such Registrable Shares and use its best efforts to cause that Registration
     Statement to become effective as soon as possible;

          (ii) as expeditiously as possible, prepare and file with the
     Commission any amendments and supplements to the Registration Statement and
     the prospectus included in the Registration Statement as may be necessary
     to comply with the provisions of the Securities Act (including the anti-
     fraud provisions thereof) and to keep the Registration Statement effective
     for 12 months from the effective date or such lesser period until all such
     Registrable Shares are sold;

                                       5
<PAGE>

          (iii) as expeditiously as possible, furnish to each Selling
     Stockholder such reasonable numbers of copies of the Prospectus, including
     any preliminary Prospectus, in conformity with the requirements of the
     Securities Act, and such other documents as such Selling Stockholder may
     reasonably request in order to facilitate the public sale or other
     disposition of the Registrable Shares owned by such Selling Stockholder;

          (iv) as expeditiously as possible, use its best efforts to register or
     qualify the Registrable Shares covered by the Registration Statement under
     the securities or Blue Sky laws of such states as the Selling Stockholders
     shall reasonably request and do any and all other acts and things that may
     be necessary or desirable to enable the Selling Stockholders to consummate
     the public sale or other disposition in such states of the Registrable
     Shares owned by the Selling Stockholder; provided, however, that the
     Company shall not be required in connection with this paragraph (iv) to
     qualify as a foreign corporation or execute a general consent to service of
     process in any jurisdiction;

          (v) as expeditiously as possible, cause all such Registrable Shares to
     be listed on each securities exchange or automated quotation system on
     which similar securities issued by the Company are then listed; and

          (vi) promptly make available for inspection by the Selling
     Stockholders, any managing underwriter participating in any disposition
     pursuant to such Registration Statement and any attorney or accountant or
     other agent retained by any such underwriter or selected by the Selling
     Stockholders, all financial and other records, pertinent corporate
     documents and properties of the Company and cause the Company's officers,
     directors, employees and independent accountants to supply all information
     reasonably requested by any such Selling Stockholder, underwriter,
     attorney, accountant or agent in connection with such Registration
     Statement.

     (b)  If the Company has delivered a Prospectus to the Selling Stockholders,
and after having done so, the Prospectus is amended to comply with the
requirements of the Securities Act, the Company shall promptly notify the
Selling Stockholders and, if requested, the Selling Stockholders shall
immediately cease making offers of Registrable Shares and return all
Prospectuses to the Company. The Company shall promptly provide the Selling
Stockholders with revised Prospectuses, and following receipt of the revised
Prospectuses, the Selling Stock holders shall be free to resume making offers of
the Registrable Shares.

     (c)  In the event that, in the judgment of the Company, it is advisable to
suspend use of a Prospectus included in a Registration Statement due to pending
material developments or other events that have not yet been publicly disclosed

                                       6
<PAGE>

and as to which the Company believes public disclosure would be detrimental to
the Company, the Company shall notify all Selling Stockholders to such effect,
and upon receipt of such notice, each such Selling Stockholder shall immediately
discontinue any sales of Registrable Shares pursuant to such Registration
Statement until such Selling Stockholder has received copies of a supplemented
or amended Prospectus or until such Selling Stockholder is advised in writing by
the Company that the then current Prospectus may be used and has received copies
of any additional or supplemental filings that are incorporated or deemed
incorporated by reference in such Prospectus. Notwithstanding anything to the
contrary herein, the Company shall not exercise its rights under this Section
2.3(c) to suspend sales of Registrable Shares for a period in excess of 90 days
in any 365-day period.

     2.4  Allocation of Expenses.  The Company will pay all Registration
Expenses for all registrations under this Agreement; provided, however, that if
a registration under Section 2.1 is withdrawn at the request of the Initiating
Holders (other than as a result of information concerning the business or
financial condition of the Company which is made known to the Stockholders after
the date on which such registration was requested) and if the Initiating Holders
elect not to have such registration counted as a registration requested under
Section 2.1, the requesting Stockholders shall pay the Registration Expenses of
such registration pro rata in accordance with the number of their Registrable
Shares included in such registration. For purposes of this Section, the term
"REGISTRATION EXPENSES" shall mean all expenses incurred by the Company in
complying with this Agreement, including, without limitation, all registration
and filing fees, exchange listing fees, printing expenses, fees and expenses of
counsel for the Company and the fees and expenses of one counsel selected by the
Selling Stockholders to represent the Selling Stockholders, state Blue Sky fees
and expenses and the expense of any special audits incident to or required by
any such registration, but excluding underwriting discounts, selling commissions
and the fees and expenses of Selling Stockholders' own counsel (other than the
counsel selected to represent all Selling Stockholders).

     2.5  Indemnification and Contribution.

     (a)  In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, the Company will indemnify
and hold harmless the Selling Stockholder, each underwriter of such Registrable
Shares and each other person, if any, who controls such Selling Stockholder or
underwriter within the meaning of the Securities Act or the Exchange Act against
any losses, claims, damages or liabilities, joint or several, to which such
Selling Stockholder, underwriter or controlling person may become subject under
the Securities Act, the Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) (i) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in any Registration
Statement under which such Registrable Shares were registered under the
Securities Act, any preliminary


                                       7
<PAGE>

prospectus or final prospectus contained in the Registration Statement or any
amendment or supplement to such Registration Statement or (ii) arise out of or
are based upon the omission or alleged omission to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading; and the Company will reimburse such Selling Stockholder, underwriter
and controlling person for any legal or any other expenses reasonably incurred
by such Selling Stockholder, underwriter or controlling person in connection
with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the Company will not be liable in any such case
to the extent that any such loss, claim, damage or liability arises out of or is
based upon any untrue statement or omission made in such Registration Statement,
preliminary prospectus or prospectus, or any such amendment or supplement, in
reliance upon and in conformity with information furnished to the Company, in
writing, by or on behalf of such Selling Stockholder, underwriter or controlling
person specifically for use in the preparation thereof.

     (b)  In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, each Selling Stockholder,
severally and not jointly, will indemnify and hold harmless the Company, each of
its directors and officers and each underwriter (if any) and each person, if
any, who controls the Company or any such underwriter within the meaning of the
Securities Act or the Exchange Act, against any losses, claims, damages or
liabilities, joint or several, to which the Company, such directors and
officers, underwriter or controlling person may become subject under the
Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) (i) arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in any Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary prospectus or final prospectus contained in the Registration
Statement or any amendment or supplement to the Registration Statement or (ii)
arise out of or are based upon any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if the statement or omission was made in reliance upon
and in conformity with information relating to such Selling Stockholder
furnished in writing to the Company by or on behalf of such Selling Stockholder
specifically for use in connection with the preparation of such Registration
Statement, prospectus, amendment or supplement; provided, however, that the
obligations of a Selling Stockholder hereunder shall be limited to an amount
equal to the net proceeds to such Selling Stockholder of Registrable Shares sold
in connection with such registration.

     (c)  Each party entitled to indemnification under this Section 2.5 (the
"INDEMNIFIED PARTY") shall give notice to the party required to provide
indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought and shall
permit the Indemnifying Party to assume the defense of any such claim

                                       8
<PAGE>

or any litigation resulting therefrom; provided, that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld); and, provided, further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 2.5 except to the
extent that the Indemnifying Party is adversely affected by such failure. The
Indemnified Party may participate in such defense at such Indemnified Party's
expense; provided, however, that the Indemnifying Party shall pay such expense
if representation of such Indemnified Party by the counsel retained by the
Indemnifying Party would be inappropriate due to actual or potential differing
interests between the Indemnified Party and any other party represented by such
counsel in such proceeding; provided further that in no event shall the
Indemnifying Party be required to pay the expenses of more than one law firm per
jurisdiction as counsel for the Indemnified Party. The Indemnifying Party also
shall be responsible for the expenses of such defense if the Indemnifying Party
does not elect to assume such defense. No Indemnifying Party, in the defense of
any such claim or litigation shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
of such claim or litigation, and no Indemnified Party shall consent to entry of
any judgment or settle such claim or litigation without the prior written
consent of the Indemnifying Party, which consent shall not be unreasonably
withheld.

     (d)  In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in this Section 2.5 is
due in accordance with its terms but for any reason is held to be unavailable to
an Indemnified Party in respect to any losses, claims, damages and liabilities
referred to herein, then the Indemnifying Party shall, in lieu of indemnifying
such Indemnified Party, contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities to
which such party may be subject in such proportion as is appropriate to reflect
the relative fault of the Company on the one hand and the Selling Stockholders
on the other in connection with the statements or omissions which resulted in
such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations. The relative fault of the Company and the Selling
Stockholders shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of material fact related to information
supplied by the Company or the Selling Stockholders and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Company and the Stockholders agree that it would
not be just and equitable if contribution pursuant to this Section 2.5 were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this Section 2.5(d), (a) in no case shall any
one Selling Stockholder be liable or responsible for any amount in excess of the
net proceeds received by such Selling Stockholder from the offering


                                       9
<PAGE>

of Registrable Shares and (b) the Company shall be liable and responsible for
any amount in excess of such proceeds; provided, however, that 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. Any party entitled to contribution
will, promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties under this Section 2.5(d), notify such
party or parties from whom contribution may be sought, but the omission so to
notify such party or parties from whom contribution may be sought shall not
relieve such party from any other obligation it may have thereunder or otherwise
under this Section 2.5(d). No party shall be liable for contribution with
respect to any action, suit, proceeding or claim settled without its prior
written consent, which consent shall not be unreasonably withheld.

     2.6  Other Matters with Respect to Underwritten Offerings.  In the event
that Registrable Shares are sold pursuant to a Registration Statement in an
underwritten offering pursuant to Section 2.1, the Company agrees to enter into
an underwriting agreement containing customary representations and warranties
with respect to the business and operations of the Company and customary
covenants and agreements to be performed by the Company, including without
limitation customary provisions with respect to indemnification by the Company
of the underwriters of such offering.

     2.7  Information by Holder.  Each Selling Stockholder shall furnish to the
Company such information regarding such Selling Stockholder and the distribution
proposed by such Selling Stockholder as the Company may reasonably request in
writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Agreement.

III.  General.

     3.1  Severability.  The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement.

     3.2  Specific Performance.  In addition to any and all other remedies that
may be available at law in the event of any breach of this Agreement, each
Purchaser shall be entitled to specific performance of the agreements and
obligations of the Company hereunder and to such other injunctive or other
equitable relief as may be granted by a court of competent jurisdiction.

     3.3  Transfers of Rights.  The rights and obligations of the Purchasers
under Section 2 may be assigned by either Purchaser to any person or entity that
acquires shares of Common Stock having an aggregate value of at least $2,500,000
(as adjusted in stock splits and similar events) from such Purchaser.  In the
event of any such assignment, the assignee must provide written notice of

                                      10
<PAGE>

such assignment to the Company and agree in writing to be bound by the
applicable provisions of this Agreement.

     3.4  Governing Law.  This Agreement shall be governed by and construed in
accordance with the laws of the state of New York.

     3.5  Notices.  All notices, requests and other communications to any party
