          Section 2.2. Restrictive Legends. (a) The Warrant Certificates shall
          -----------  -------------------
bear substantially the following legend on the face thereof:

     THE WARRANTS REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
     "SECURITIES ACT"), AND ACCORDINGLY, MAY NOT BE OFFERED, SOLD,
     PLEDGED OR OTHERWISE TRANSFERRED WITHIN THE UNITED STATES OR TO,
     OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET
     FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE
     HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL
     BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B)
     IT IS AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE
     501(a)(1), (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES
     ACT) (AN "INSTITUTIONAL ACCREDITED INVESTOR"), (2) AGREES THAT IT
     WILL NOT, WITHIN THE TIME PERIOD REFERRED TO UNDER RULE 144(k)
     UNDER THE SECURITIES ACT AS IN EFFECT WITH RESPECT TO SUCH
     TRANSFER, RESELL OR OTHERWISE TRANSFER THE WARRANTS REPRESENTED
     BY THIS CERTIFICATE EXCEPT (A) TO LOUDCLOUD, INC. (THE "COMPANY")
     OR ANY SUBSIDIARY THEREOF, (B) FOLLOWING THE RULE 144A
     AVAILABILITY DATE, TO A QUALIFIED INSTITUTIONAL BUYER IN
     COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) TO AN
     INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER,
     FURNISHES TO THE WARRANT AGENT A SIGNED LETTER CONTAINING CERTAIN
     REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON
     TRANSFER OF THE WARRANTS REPRESENTED BY THIS CERTIFICATE (THE
     FORM OF WHICH LETTER CAN BE OBTAINED FROM THE WARRANT AGENT) AND
     IF SUCH TRANSFER IS IN RESPECT OF ANY WARRANTS SUBSEQUENT TO THE
     DATE ON WHICH THE WARRANTS REPRESENTED HEREBY BECOME SEPARATELY
     TRANSFERABLE, AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY
     THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT, (D)
     PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144
     UNDER THE SECURITIES ACT (IF AVAILABLE) OR (E) PURSUANT TO AN
     EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3)
     AGREES THAT IT WILL DELIVER TO EACH PERSON TO

                                       8

     WHOM THE WARRANTS REPRESENTED BY THIS CERTIFICATE ARE TRANSFERRED A NOTICE
     SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH ANY TRANSFER
     OF THE WARRANTS REPRESENTED BY THIS CERTIFICATE WITHIN THE TIME PERIOD
     REFERRED TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON
     THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS
     CERTIFICATE TO THE WARRANT AGENT. IF THE PROPOSED TRANSFEREE IS AN
     INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER,
     FURNISH TO EACH OF THE WARRANT AGENT AND THE COMPANY SUCH CERTIFICATIONS,
     LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY
     REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
     EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
     REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS "UNITED
     STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S
     UNDER THE SECURITIES ACT. THE WARRANT AGREEMENT CONTAINS A PROVISION
     REQUIRING THE WARRANT AGENT TO REFUSE TO REGISTER ANY TRANSFER OF THE
     WARRANTS REPRESENTED BY THIS CERTIFICATE IN VIOLATION OF THE FOREGOING
     RESTRICTIONS. THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO CERTAIN
     RESTRICTIONS ON TRANSFER INCLUDING A 180-DAY LOCKUP IN CONNECTION WITH AN
     INITIAL PUBLIC OFFERING AS SET FORTH IN THE WARRANT AGREEMENT, A COPY OF
     WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY. SUCH TRANSFER
     RESTRICTIONS ARE BINDING ON TRANSFEREES OF THIS WARRANT CERTIFICATE.

          (b)  Each Restricted Global Warrant shall also bear the following

     OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
     WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN
     INTEREST HEREIN.

     TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS
     IN WHOLE, BUT NOT IN PART, TO NOMINEES OF THE DEPOSITORY TRUST
     COMPANY OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND

     ARTICLE VIII OF THE WARRANT AGREEMENT.

          (c)  Each Warrant Certificate issued prior to the Separation Date
shall bear the following legend on the face thereof:

     RESPECT TO RESALES OF THE NOTES, (iv) A REDEMPTION DATE AND (v)
     SUCH DATE AS DETERMINED BY MORGAN STANLEY & CO. INCORPORATED IN
     ITS SOLE DISCRETION, THE WARRANTS EVIDENCED BY THIS CERTIFICATE
     MAY NOT BE TRANSFERRED OR EXCHANGED SEPARATELY FROM, BUT MAY BE
     TRANSFERRED OR EXCHANGED ONLY TOGETHER WITH, THE NOTES.

          Section 2.3. Execution and Delivery of Warrant Certificates. Warrant
          -----------  ----------------------------------------------
Certificates evidencing 66,000 Warrants, each Warrant to purchase 35.39448485
Common Shares, may be executed, on or after the date of this Agreement, by the
Company and delivered to the Warrant Agent for countersignature, and the Warrant
Agent shall thereupon countersign and deliver such Warrant Certificates upon the
order and at the written direction of the Company signed by its Chief Executive
Officer or other duly authorized executive officer to the purchasers thereof on
the date of issuance. The Warrant Agent is hereby authorized to countersign and
deliver Warrant Certificates as required by this Section 2.3 or by Section 3.3,

          The Warrant Certificates shall be executed on behalf of the Company by
its Chairman of the Board, Chief Executive Officer, any Vice President or other
duly authorized executive officer of the Company either manually or by facsimile
signature printed thereon. The Warrant Certificates shall be countersigned by
manual signature of the Warrant Agent and shall not be valid for any purpose
unless so countersigned. In case any officer or director of the Company whose
signature shall have been placed upon any of the Warrant Certificates shall
cease to be such officer or director of the Company before countersignature by
the Warrant Agent and the issuance and delivery thereof, such Warrant
Certificates may nevertheless be countersigned by the Warrant Agent and issued
and delivered with the same force and effect as though such person had not
ceased to be such officer or director of the Company.

          Section 2.4. Certificated Warrants. Beneficial owners of interests in
          -----------  ---------------------
a Restricted Global Warrant may receive Certificated Warrants (which, except as
set forth in Section 8.3(c), shall bear the Private Placement Legend) in
accordance with the procedures of the Warrant Agent and the Depositary. In
connection with the execution and delivery of such Certificated Warrants, the
Warrant Agent shall reflect on its books and records the date and a decrease in
the number of Warrants represented by the relevant Restricted Global Warrant
equal to the number of such Certificated Warrants and the Company shall execute
and the Warrant Agent shall countersign and deliver to said beneficial owners
one or more Certificated Warrants in an equal aggregate number.

                                  ARTICLE III

              EXERCISE PRICE, EXERCISE AND REPURCHASE OF WARRANTS

          Section 3.1. Exercise Price. Each Warrant Certificate shall, when
          -----------  --------------
countersigned by the Warrant Agent, initially entitle the Holder thereof,
subject to the provisions of this Agreement, to purchase the number of Common
Shares indicated thereon at a purchase price (the "Exercise Price") of $.01 per
                                                   --------------
Common Share, subject to adjustment as provided in Section 4.1 and Article V
hereof.

          Section 3.2. Exercise; Restrictions on Exercise. At any time after the
          -----------  ----------------------------------
Closing Date and on or before the Expiration Date, any outstanding Warrants may
be exercised on any Business Day; provided that the Warrants will be exercisable
in connection with the initial public offering of equity securities (other than
nonconvertible preferred shares or an offering registered solely on Form S-4 or
S-8 or any successor form thereto) of the Company if the Holders are entitled to
include their Common Shares in such offering and provided further that the
Warrant Registration Statement is, at the time of exercise, effective and
available for the exercise of the Warrants or the exercise of such Warrants is
exempt from the registration requirements of the Securities Act. Any Warrants
not exercised by 5:00 p.m., New York City time, on the Expiration Date shall
expire and all rights of the Holders of such Warrants shall terminate.
<PAGE>

                                       11

Additionally, pursuant to Section 4.1(f)(ii) hereof, the Warrants shall expire
and all rights of the Holders of such Warrants shall terminate in the event the
Company merges or consolidates with or sells all or substantially all of its
property and assets to a Person (other than an Affiliate of the Company) if the
consideration payable to holders of Common Stock in exchange for their Common
Stock in connection with such merger, consolidation or sale consists solely of
cash or in the event of the dissolution, liquidation or winding up of the
Company.

          Section 3.3. Method of Exercise; Payment of Exercise Price. In order
          -----------  ---------------------------------------------
to exercise all or any of the Warrants represented by a Warrant Certificate, the
Holder thereof must surrender for exercise the Warrant Certificate to the
Warrant Agent at its corporate trust office address set forth in Section 12.6
hereof, with the Subscription Form set forth on the reverse of the Warrant
Certificate duly executed, together with payment in full of the Exercise Price
then in effect for each Common Share (or other securities) issuable upon
exercise of the Warrants as to which a Warrant is exercised; such payment may be
made in cash or by certified or official bank or bank cashier's check payable to
the order of the Company and shall be made to the Warrant Agent at its corporate
trust office address set forth in Section 12.6 hereof prior to the close of
business on the date the Warrant Certificate is surrendered to the Warrant Agent
for exercise. Notwithstanding the foregoing, the Exercise Price may be paid by
surrendering additional Warrants to the Warrant Agent having an aggregate Spread
equal to the aggregate Exercise Price of the Warrants being exercised. All
payments received upon exercise of Warrants shall be delivered to the Company by
the Warrant Agent as instructed in writing by the Company. If less than all the
Warrants represented by a Warrant Certificate are exercised or surrendered (in
connection with a cashless exercise), such Warrant Certificate shall be
surrendered and a new Warrant Certificate of the same tenor and for the number
of Warrants which were not exercised or surrendered shall be executed by the
Company and delivered to the Warrant Agent and the Warrant Agent shall
countersign the new Warrant Certificate, registered in such name or names as may
be directed in writing by the Holder, and shall make available for delivery the
new Warrant Certificate to the Person or Persons entitled to receive the same.
Restricted Global Warrants will be exercised in accordance with the procedures
of the Warrant Agent and the Depositary. Upon the exercise of any Warrants
following the surrender of a Warrant Certificate in conformity with the
foregoing provisions, the Warrant Agent shall instruct the Company to transfer
promptly to the Holder or, upon the written order of the Holder of such Warrant
Certificate, appropriate evidence of ownership of any Common Shares or other
security or property to which it is entitled, registered or otherwise placed in
such name or names as may be directed in writing by the Holder, and to deliver
such evidence of ownership to the Person or Persons entitled to receive the same
and fractional shares, if any, or an amount in cash, in lieu of any fractional
shares, as provided in Section 4.5 hereof; provided that the Holder of such
Warrant shall be responsible for the payment of any transfer taxes required as
the result of any change in ownership of such Warrants or the issuance of such
Common Shares other than to the Holder of such Warrants and any such transfer
shall comply with applicable law. Upon the exercise of a Warrant or Warrants,
the Warrant Agent is hereby authorized and directed to requisition from any
transfer agent of the Common Shares (and all such transfer agents are
<PAGE>

                                       12

hereby irrevocably authorized to comply with all such requests) certificates
(bearing the legend set forth in Section 12.11 hereof, if applicable, unless a
registration statement with the Commission relating to such Common Shares shall
then be in effect or the Company and the Holder exercising such Warrant or
Warrants otherwise agree) for the number of Common Shares to which said Holder
may be entitled. The Company shall enter, or shall cause any transfer agent of
the Common Shares to enter, the name of the Person entitled to receive the
Common Shares upon exercise of the Warrants into the Company's register of
stockholders within 14 days of such exercise. A Warrant shall be deemed to have
been exercised immediately prior to the close of business on the date of the
surrender for exercise, as provided above, of the Warrant Certificate
representing such Warrant and, for all purposes under this Agreement, the Person
entitled to receive any Common Shares deliverable upon such exercise shall, as
between such Person and the Company, be deemed to be the Holder of such Common
Shares of record as of the close of business on such date and shall be entitled
to receive, and the Warrant Agent shall make available for delivery to such
Person, any Common Shares to which such Person would have been entitled had such
Person been the registered holder on such date.

          Section 3.4. Repurchase Offers. (a) Notice of Repurchase Event. Within
          -----------  -----------------      --------------------------
five Business Days following the occurrence of a Repurchase Event, the Company
shall give notice (a "Repurchase Notice") to the Holders of the Warrants and the
                      -----------------
Warrant Agent that such event has occurred.

          (b)  Repurchase Offers Generally. Following the occurrence of a
               ---------------------------
Repurchase Event, the Company shall offer to repurchase for cash all outstanding
Warrants pursuant to the provisions of this Section 3.4 (a "Repurchase Offer").
                                                            ----------------
The Company shall give notice of a Repurchase Offer in accordance with Section
3.4(f) hereof. Each date on which the Company gives any such notice is referred
to as the "Notice Date." The Repurchase Offer shall commence on the Notice Date
           -----------
for such Repurchase Offer and shall expire at 5:00 p.m., New York City time, on
a date determined by the Company (the "Final Surrender Time") that is at least
                                       --------------------
30 but not more than 60 days after the Notice Date. Once a Repurchase Event has
occurred, there is no limit on the number of Repurchase Offers that the Company
may make.

          (c)  Repurchase Offers. (i) In any Repurchase Offer, the Company shall
               -----------------
offer to purchase for cash at the Repurchase Price all Warrants outstanding on
the Notice Date for such Repurchase Offer that are properly tendered to the
Warrant Agent on or prior to the Final Surrender Time for such Repurchase Offer.

          (ii) Each Holder may, but shall not be obligated to, accept such
Repurchase Offer by tendering to the Warrant Agent, on or prior to the Final
Surrender Time for such Repurchase Offer, the Warrant Certificates evidencing
the Warrants such Holder desires to have repurchased in such offer, together
with a completed Certificate for Surrender in substantially the form attached to
the Warrant Certificate. A Holder may withdraw all or a portion of the Warrants
tendered to the Warrant Agent at any time prior to the Final Surrender Time for
such
<PAGE>

                                       13

Repurchase Offer. If less than all the Warrants represented by a Warrant
Certificate shall be tendered, such Warrant Certificate shall be surrendered and
a new Warrant Certificate of the same tenor and for the number of Warrants which
were not tendered shall be executed by the Company and delivered to the Warrant
Agent and the Warrant Agent shall countersign the new Warrant Certificate,
registered in such name or names as may be directed in writing by the Holder,
and shall make available for delivery the new Warrant Certificate to the Person
or Persons entitled to receive the same; provided that the Holder of such
Warrants shall be responsible for the payment of any transfer taxes required as
the result of any change in ownership of such Warrants and any such transfer
shall comply with applicable law.

          (d)  Repurchase Price. (i) The purchase price (the "Repurchase Price")
               ----------------                               ----------------
for each Warrant properly tendered to the Warrant Agent pursuant to a Repurchase
Offer shall be equal to the value (the "Relevant Value") on the Valuation Date
                                        --------------
of the Common Shares issuable, and other securities or property of the Company
which would have been delivered, upon exercise of Warrants had the Warrants been
exercised (regardless of whether the Warrants are then exercisable), less the
Exercise Price in effect on the Notice Date for such Repurchase Offer.

          (ii) The Relevant Value of the Common Shares and other securities or
property issuable upon exercise of all the Warrants, on any Valuation Date shall
be:

          (1)  (A) If the Common Shares (or other securities) are registered
     under the Exchange Act, deemed to be the average of the daily market prices
     (on the stock exchange that is the primary trading market for the Common
     Shares (or other securities)) of the Common Shares (or other securities)
     for the 20 consecutive trading days immediately preceding such Valuation
     Date or, (B) if the Common Shares (or other securities) have been
     registered under the Exchange Act for less than 20 consecutive trading days
     before such date, then the average of the daily market prices for all of
     the trading days before such date for which daily market prices are
     available, in the case of each of (A) and (B), as certified to the Warrant
     Agent by the President, any Vice President or the Chief Financial Officer
     of the Company (the "Value Certificate"). The market price for each such
                          -----------------
     trading day shall be: (A) in the case of a security listed or admitted to
     trading on any national securities exchange, the closing sales price on
     such day, or if no sale takes place on such day, the average of the closing
     bid and asked prices on such day, (B) in the case of a security not then
     listed or admitted to trading on any national securities exchange, the last
     reported sale price on such day, or if no sale takes place on such day, the
     average of the closing bid and asked prices on such day, as reported by a
     reputable quotation source designated by the Company, (C) in the case of a
     security not then listed or admitted to trading on any national securities
     exchange and as to which no such reported sale price or bid and asked
     prices are available, the average of the reported high bid and low asked
     prices on such day, as reported by a reputable quotation service, or a
     newspaper of general circulation in the Borough of Manhattan, City and
     State of New York customarily published on each Business Day, designated by
<PAGE>

                                       14

     the Company, or, if there shall be no bid and asked prices on such day, the
     average of the high bid and low asked prices, as so reported, on the most
     recent day (not more than 30 days prior to the date in question) for which
     prices have been so reported and (D) if there are no bid and asked prices
     reported during the 30 days prior to the date in question, the Relevant
     Value shall be determined as if the Common Shares (or other securities)
     were not registered under the Exchange Act; or

          (2)  If the Common Shares (or other securities) are not registered
     under the Exchange Act or if the value cannot be computed under clause (1)
     above, deemed to be equal to the value set forth in the Value Report (as
     defined below) as determined by an Independent Financial Expert, which
     shall be selected by the Board in accordance with Section 3.4(e) hereof,
     and retained on customary terms and conditions, using one or more valuation
     methods that the Independent Financial Expert, in its best professional
     judgment, determines to be most appropriate but without giving effect to
     any discount for lack of liquidity, the fact that the Company has no class
     of equity securities registered under the Exchange Act or the fact that the
     Common Shares and other securities or property issuable upon exercise of
     the Warrants represent a minority interest in the Company. The Company
     shall cause the Independent Financial Expert to deliver to the Company,
     with a copy to the Warrant Agent, within 45 days of the appointment of the
     Independent Financial Expert in accordance with Section 3.4(e) hereof, a
     value report (the "Value Report") stating the Relevant Value of the Common
                        ------------
     Shares and other securities or property of the Company, if any, being
     valued as of the Valuation Date and containing a brief statement as to the
     nature and scope of the examination, investigation and methodologies upon
     which the determination of Relevant Value was made. The Warrant Agent shall
     have no duty with respect to the Value Report of any Independent Financial
     Expert, except to keep it on file and available for inspection by the
     Holders. The determination as to Relevant Value in accordance with the
     provisions of this Section 3.4(d) shall be conclusive on all Persons. The
     Independent Financial Expert shall consult with management of the Company
     in order to allow management to comment on the proposed Relevant Value
     prior to delivery to the Company of any Value Report of the Independent
     Financial Expert.

          (e)  Selection of Independent Financial Expert. If clause (d)(ii)(2)
               -----------------------------------------
of this Section 3.4 is applicable, the Board of Directors of the Company shall
select an Independent Financial Expert not more than five Business Days
following a Repurchase Event. Within seven Business Days following a Repurchase
Event, the Company shall deliver to the Warrant Agent a notice setting forth the
name of the Independent Financial Expert.

          (f)  Notice of Repurchase Offer. Each notice of a Repurchase Offer (an
               ---------------------------
"Offer Notice") given by the Company pursuant to Section 3.4(b) shall be given
 ----- ------
by the Company directly to all Holders of the Warrants, with a copy to the
Warrant Agent, shall be given simultaneously with the Repurchase Notice (or, in
the event that the Relevant Value of the
<PAGE>

                                       15

Common Shares or other securities or property issuable upon exercise of all the
Warrants cannot be determined pursuant to Section 3.4(d)(ii)(1), then such Offer
Notice shall be given within five Business Days after the Company receives the
Value Report with respect to such offer) and shall specify (A) the Final
Surrender Time for such Repurchase Offer, (B) the manner in which Warrants may
be surrendered to the Warrant Agent for repurchase by the Company, (C) the
Repurchase Price at which the Warrants will be repurchased by the Company, (D)
if applicable, the name of the Independent Financial Expert whose valuation of
the Common Shares and other securities or property was utilized in connection
with determining such Repurchase Price and (E) that payment of the Repurchase
Price will be made by the Warrant Agent. Each such notice shall be accompanied
by a Certificate for Surrender for Repurchase Offer in substantially the form
attached to the Warrant Certificate and a copy of the Value Report, if any.

          (g)  Payment for Warrants. Upon surrender for repurchase of any
               --------------------
Warrants in conformity with the provisions of this Section 3.4, the Warrant
Agent shall thereupon promptly notify the Company of such surrender. On or
before the Final Surrender Time for any Repurchase Offer, the Company shall
deposit with the Warrant Agent funds sufficient to make payment for the Warrants
tendered to the Warrant Agent and not withdrawn. After receipt of such deposit
from the Company, the Warrant Agent shall make payment, by delivering a check in
such amount as is appropriate, to such Person or Persons as it may be directed
in writing by the Holder surrendering such Warrants, net of any transfer taxes
required to be paid in the event that the check is to be delivered to a Person
other than the Holder.

          (h)  Compliance with Laws. Notwithstanding anything contained in this
               --------------------
Section 3.4, if the Company is required to comply with laws, rules, regulations
and securities exchange or clearing procedures, in connection with making any
Repurchase Offer, such laws, rules, regulations and procedures shall govern the
making of such Repurchase Offer.

                                  ARTICLE IV

                                  ADJUSTMENTS

          Section 4.1. Adjustments. The Exercise Price and the number of Common
          -----------  -----------
Shares issuable upon exercise of each Warrant shall be subject to adjustment
from time to time as follows:

          (a)  Divisions; Consolidations; Reclassifications. In case the Company
               --------------------------------------------
     shall, on or before the Expiration Date, (i) issue any Common Shares in
     payment of a dividend or other distribution with respect to its Common
     Stock, (ii) subdivide its issued and outstanding Common Shares, (iii)
     consolidate its issued and outstanding Common Shares into a smaller number
     of shares, or (iv) reclassify or convert the Common Shares (other than a
     reclassification in connection with a merger, consolidation or other
     business
<PAGE>

                                       16

     combination which will be governed by Section 4.1(f)), then the number of
     Common Shares purchasable upon exercise of each Warrant immediately prior
     to the record date for such issue or distribution or the effective date of
     such subdivision, consolidation, reclassification or conversion shall be
     adjusted so that the Holder of each Warrant shall thereafter be entitled to
     receive the kind and number of Common Shares which such Holder would have
     been entitled to receive after the happening of any of the events described
     above had such Warrant been exercised immediately prior to the happening of
     such event or any record date with respect thereto. An adjustment made
     pursuant to this Section 4.1(a) shall become effective immediately after
     the effective date of such event retroactive to the record date, if any,
     for such event.

          (b)  Distributions of Debt or Assets. In case the Company shall make a
               -------------------------------
     distribution to all holders of its Common Shares of evidences of its
     indebtedness, or assets, or other distributions (excluding any issuance of
     Common Shares referred to in Section 4.1(a) above and excluding
     distributions in connection with the dissolution, liquidation or winding-up
     of the Company which shall be governed by Section 4.1(f) and distributions
     of securities referred to in Section 4.1(a), then provision shall be made
     so that the Holders shall receive upon exercise of their warrants the
     amount of such evidences of Indebtedness, assets or other distributions
     that they would have received had their Warrants been exercised on the date
     of such event (or the record date thereof), subject to all other
     adjustments called for with respect to the rights of the Holders of the
     Warrants or with respect to such other securities by their terms.

          (c)  Current Market Value. For the purposes of any computation under
               --------------------
     this Article IV, the "Current Market Value" per Common Share or of any
                           --------------------
     other security (herein collectively referred to as a "security") at any
                                                           --------
     date herein specified shall be:

               (i)  if the security is not registered under the Exchange Act,
          the value of the security determined in good faith by the Board and
          certified in a Board resolution, which shall not be lower than the
          most recently completed arms-length transaction between the Company
          and a Person other than an Affiliate of the Company or the most
          recently determined fair market value of the security as determined by
          an Independent Financial Expert selected by the Company in accordance
          with the criteria for such valuation set out in Section 4.1(c)(iii) or

               (ii) if the security is registered under the Exchange Act, the
          average of the daily market prices of the security for the 20
          consecutive trading days immediately preceding such date or, if the
          security has been registered under the Exchange Act for less than 20
          consecutive trading days before such date, then the average of the
          daily market prices for all of the trading days before such date for
          which daily market prices are available. The market price for each
          such trading day shall be: (A) in the case of a security listed or
          admitted to trading on any
<PAGE>

                                       17

          national securities exchange, the closing sales price, regular way, on
          such day, or if no sale takes place on such day, the average of the
          closing bid and asked prices on such day on the principal national
          securities exchange on which such security is listed or admitted, as
          determined by the Board, in good faith, (B) in the case of a security
          not then listed or admitted to trading on any national securities
          exchange, the last reported sale price on such day, or if no sale
          takes place on such day, the average of the closing bid and asked
          prices on such day, as reported by a reputable quotation source
          designated by the Company, (C) in the case of a security not then
          listed or admitted to trading on any national securities exchange and
          as to which no such reported sale price or bid and asked prices are
          available, the average of the reported high bid and low asked prices
          on such day, as reported by a reputable quotation service, or a
          newspaper of general circulation in the Borough of Manhattan, City and
          State of New York customarily published on each Business Day,
          designated by the Company, or, if there shall be no bid and asked
          prices on such day, the average of the high bid and low asked prices,
          as so reported, on the most recent day (not more than 30 days prior to
          the date in question) for which prices have been so reported and (D)
          if there are no bid and asked prices reported during the 30 days prior
          to the date in question, the Current Market Value of the security
          shall be determined as if the security were not registered under the
          Exchange Act.

               (iii) If required pursuant to Section 4.1(c)(i), the Current
          Market Value shall be deemed to be equal to the value set forth in the
          Value Report (as defined below) as determined by an Independent
          Financial Expert, which shall be selected by the Board in its sole
          discretion, and retained on customary terms and conditions, using one
          or more valuation methods that the Independent Financial Expert, in
          its professional judgment, determines to be most appropriate. The
          Company shall cause the Independent Financial Expert to deliver to the
          Company, with a copy to the Warrant Agent, within 45 days of the
          appointment of the Independent Financial Expert, a value report (the
          "Value Report") stating the value of the Common Shares and other
           ------------
          securities or property of the Company, if any, being valued as of the
          Valuation Date and containing a brief statement as to the nature and
          scope of the examination, investigation and methodologies upon which
          the determination of value was made. The Warrant Agent shall have no
          duty with respect to the Value Report of any Independent Financial
          Expert, except to keep it on file and available for inspection by the
          Holders. The determination as to Current Market Value in accordance
          with the provisions of this Section 4.1(c)(iii) shall be conclusive on
          all Persons. The Independent Financial Expert shall consult with
          management of the Company in order to allow management to comment on
          the proposed value prior to delivery to the Company of any Value
          Report.

          (d)  De Minimis Adjustments. No adjustment in the number of Common
               ----------------------
     Shares purchasable hereunder shall be required unless such adjustment would
     require an increase or decrease of at least one percent (1%) in the number
     of Common Shares purchasable upon the exercise of each Warrant; provided,
     however, that any adjustments which by reason of this Section 4.1(d) are
     not required to be made shall be carried forward and taken into account in
     any subsequent adjustment. All calculations shall be made to the nearest
     one-thousandth of a share.

          (e)  Adjustment of Exercise Price. Whenever the number of Common
               ----------------------------
     Shares purchasable upon the exercise of each Warrant is adjusted, as herein
     provided, the Exercise Price per Common Share payable upon exercise of such
     Warrant shall be adjusted (calculated to the nearest $.0001) so that it
     shall equal the price determined by multiplying such Exercise Price
     immediately prior to such adjustment by a fraction the numerator of which
     shall be the number of Common Shares purchasable upon the exercise of each
     Warrant immediately prior to such adjustment and the denominator of which
     shall be the number of Common Shares so purchasable immediately thereafter.

          If after an adjustment, a Holder of a Warrant upon exercise of it may
     receive shares of two or more classes in the capital of the Company, the
     Company shall determine the allocation of the adjusted Exercise Price
     between such classes of shares in a manner that the Board deems fair and
     equitable to the Holders. After such allocation, the exercise privilege and
     the Exercise Price of each class of shares shall thereafter be subject to
     adjustment on terms comparable to those applicable to Common Shares in this
     Article IV.

          Such adjustment shall be made successively whenever any event listed
     above shall occur.

          (f)  Consolidation, Merger, Etc. (i) Subject to the provisions of
               --------------------------
     Subsection (ii) below of this Section 4.1(f), in case of the consolidation
     of the Company with, or merger of the Company with or into, or of the sale
     of all or substantially all of the properties and assets of the Company to,
     any Person, and in connection therewith consideration is payable to holders
     of Common Shares (or other securities or property purchasable upon exercise
     of Warrants) in exchange therefor, the Warrants shall remain subject to the
     terms and conditions set forth in this Agreement and each Warrant shall,
     after such consolidation, merger or sale, entitle the Holder to receive
     upon exercise the number of shares in the capital or other securities or
     property (including cash) of or from the Person resulting from such
     consolidation or surviving such merger or to which such sale shall be made
     or of the parent of such Person, as the case may be, that would have been
     distributable or payable on account of the Common Shares if such Holder's
     Warrants had been exercised immediately prior to such merger, consolidation
     or sale (or, if applicable, the record date therefor); and in any such case
     the provisions of this
<PAGE>

                                       19

     Agreement with respect to the rights and interests thereafter of the
     Holders of Warrants shall be appropriately adjusted by the Board in good
     faith so as to be applicable, as nearly as may reasonably be, to any
     shares, other securities or any property thereafter deliverable on the
     exercise of the Warrants.

          (ii) Notwithstanding the foregoing, (x) if the Company merges or
     consolidates with, or sells all or substantially all of its property and
     assets to, another Person (other than an Affiliate of the Company) and
     consideration is payable to holders of Common Shares in exchange for their
     Common Shares in connection with such merger, consolidation or sale which
     consists solely of cash, or (y) in the event of the dissolution,
     liquidation or winding up of the Company, then the Holders of Warrants
     shall be entitled to receive distributions on the date of such event on an
     equal basis with holders of Common Shares (or other securities issuable
     upon exercise of the Warrants) as if the Warrants had been exercised
     immediately prior to such event, less the Exercise Price. Upon receipt of
     such payment, if any, the rights of a Holder shall terminate and cease and
     such Holder's Warrants shall expire. If the Company has made a Repurchase
     Offer that has not expired at the time of such transaction, the holders of
     the Warrants will be entitled to receive the higher of (i) the amount
     payable to the holders of the Warrants described above and (ii) the
     Repurchase Price payable to the holders of the Warrants pursuant to such
     Repurchase Offer. In case of any such merger, consolidation or sale of
     assets, the surviving or acquiring Person and, in the event of any
     dissolution, liquidation or winding up of the Company, the Company shall
     deposit promptly with the Warrant Agent the funds, if any, necessary to pay
     the Holders of the Warrants. After receipt of such deposit from such Person
     or the Company and after receipt of surrendered Warrant Certificates, the
     Warrant Agent shall make payment by delivering a check in such amount as is
     appropriate (or, in the case of consideration other than cash, such other
     consideration as is appropriate) to such Person or Persons as it may be
     directed in writing by the Holder surrendering such Warrants.

          Section 4.2. Notice of Adjustment. Whenever the number of Common
          -----------  --------------------
Shares purchasable upon the exercise of each Warrant or the Exercise Price is
adjusted, as herein provided, the Company shall cause, so far as it is able, the
Warrant Agent promptly to mail, at the expense of the Company, to each Holder
notice of such adjustment or adjustments and shall deliver to the Warrant Agent
a certificate of the Auditors setting forth the number of Common Shares
purchasable upon the exercise of each Warrant and the Exercise Price after such
adjustment, setting forth a brief statement of the facts requiring such
adjustment and setting forth the computation by which such adjustment was made.
Such certificate shall be conclusive evidence of the correctness of such
adjustment except in the case of manifest error. The Warrant Agent shall be
entitled to rely on such certificate and shall be under no duty or
responsibility with respect to any such certificate, except to exhibit the same,
from time to time, to any Holder desiring an inspection thereof during
reasonable business hours upon reasonable notice. The Warrant Agent shall not at
any time be under any duty or responsibility to any Holders to
<PAGE>

                                       20

determine whether any facts exist which may require any adjustment of the
Exercise Price or the number of Common Shares purchasable on exercise of the
Warrants or any of the other adjustments set forth in Section 4.1, or with
respect to the nature or extent of any such adjustment when made, or with
respect to the method employed in making such adjustment, or the validity or
value (or the kind or amount) of any Common Shares which may be purchasable on
exercise of the Warrants. The Warrant Agent shall not be responsible for any
failure of the Company to make any cash payment or to issue, transfer or deliver
any Common Shares or share certificates upon the exercise of any Warrant.

          Section 4.3. Statement on Warrants. Irrespective of any adjustment in
          -----------  ---------------------
the Exercise Price or the number or kind of shares purchasable upon the exercise
of the Warrants, Warrants theretofore or thereafter issued may continue to
express the same price and number and kind of shares as are stated in the
Warrants initially issuable pursuant to this Agreement.

          Section 4.4. Notice of Consolidation, Merger, Etc. In case at any time
          -----------  ------------------------------------
after the date hereof and prior to 5:00 p.m., New York City time, on the
Expiration Date, there shall be any (i) consolidation or merger involving the
Company or sale, transfer or other disposition of all or substantially all of
the Company's property, assets or business (except (1) a merger or other
reorganization in which the Company shall be the surviving corporation and
holders of Common Shares receive no consideration in respect of their shares and
(2) a merger of the Company into a wholly owned Subsidiary of the Company, the
principal purpose of which, in the good faith determination of the Board, is to
change the state of incorporation of the Company) or (ii) any other transaction
contemplated by Section 4.1(f)(ii) above then, in any one or more of such cases,
the Company shall cause to be mailed to the Warrant Agent and shall cause the
Warrant Agent to mail, at Company's expense, to each Holder of a Warrant, at the
earliest practicable time (and, in any event, not less than 20 days before any
date set for definitive action), notice of the date on which such
reorganization, sale, consolidation, merger, dissolution, liquidation or winding
up shall take place, as the case may be. Such notice shall also set forth such
facts as shall indicate the effect of such action (to the extent such effect may
be known at the date of such notice) on the Exercise Price and the kind and
amount of the Common Shares and other securities, money and other property
deliverable upon exercise of the Warrants. Such notice shall also specify the
date as of which the holders of record of the Common Shares or other securities
or property issuable upon exercise of the Warrants shall be entitled to exchange
their shares for securities, money or other property deliverable upon such
reorganization, sale, consolidation, merger, dissolution, liquidation or winding
up, as the case may be.

          Section 4.5. Fractional Interests. If more than one Warrant shall be
          -----------  --------------------
presented for exercise in full at the same time by the same Holder, the number
of full Common Shares which shall be issuable upon such exercise thereof shall
be computed on the basis of the aggregate number of Common Shares purchasable on
exercise of the Warrants so presented. The Company shall not be required to
issue fractional Common Shares upon the exercise of Warrants. If any fraction of
a Common Share would, except for the provisions of this Section 4.5, be issuable
on
<PAGE>

                                       21

the exercise of any Warrant (or specified portion thereof), the Company may pay
an amount in cash calculated by it to be equal to the then Current Market Value
per Common Share multiplied by such fraction computed to the nearest whole cent.

          Section 4.6. When Issuance or Payment May Be Deferred. In any case in
          -----------  ----------------------------------------
which this Article IV shall require that an adjustment in the Exercise Price be
made effective as of a record date for a specified event, the Company may elect
to defer until the occurrence of such event (i) issuing to the holder of any
Warrant exercised after such record date the Common Shares and other shares in
the capital of the Company, if any, issuable upon such exercise over and above
the Common Shares and other shares in the capital of the Company, if any,
issuable upon such exercise and (ii) paying such holder any amount in cash in
lieu of a fractional share; provided, however, that the Company shall deliver to
such Holder a due bill or other appropriate instrument evidencing such Holder's
right to receive such additional Common Shares, other shares and cash upon the
occurrence of the event requiring such adjustment.

          Section 4.7. Initial Public Offering. Notwithstanding anything to the
          -----------  -----------------------
contrary herein contained, if the Company or any of its subsidiaries or any
parent of the Company conducts an initial public offering of equity securities
(other than nonconvertible preferred shares or an offering registered solely on
Form S-4 or Form S-8 or any successor forms thereto), the Company will give, or
will cause its subsidiary or parent to give the Holders the opportunity to
convert their Warrants into warrants to purchase such equity securities (other
than nonconvertible preferred shares) and their Common Shares or such other
securities that have been received by the Holders upon the exercise of Warrants
into such equity securities (other than nonconvertible preferred shares). Such
conversion opportunity will be on terms and conditions determined to be fair and
reasonable by the Board.

                                   ARTICLE V

                          DECREASE IN EXERCISE PRICE

          The Board, in its sole discretion, shall have the right at any time,
or from time to time, to decrease the Exercise Price of the Warrants and/or
increase the number of shares issuable upon the exercise of the Warrants.

                                  ARTICLE VI

                              LOSS OR MUTILATION

          Upon receipt by the Company and the Warrant Agent of evidence
satisfactory to them of the ownership and the loss, theft, destruction or
mutilation of any Warrant Certificate and of indemnity or bond satisfactory to
them and (in the case of mutilation) upon surrender and
<PAGE>

                                       22

cancellation thereof, then, in the absence of notice to the Company or the
Warrant Agent that the Warrants represented thereby have been acquired by a bona
fide purchaser, the Company shall execute and the Warrant Agent shall
countersign and make available for delivery to the registered Holder of the
lost, stolen, destroyed or mutilated Warrant Certificate, in exchange for or in
lieu thereof, a new Warrant Certificate of the same tenor and for a like
aggregate number of Warrants. Upon the issuance of any new Warrant Certificate
under this Article VI, the Company may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in relation
thereto and other expenses (including the fees and expenses of the Warrant
Agent) in connection therewith. Every new Warrant Certificate executed and
delivered pursuant to this Article VI in lieu of any lost, stolen or destroyed
Warrant Certificate shall constitute a contractual obligation of the Company
whether or not the allegedly lost, stolen or destroyed Warrant Certificates
shall be at any time enforceable by anyone and shall be entitled to the benefits
of this Agreement equally and proportionately with any and all other Warrant
Certificates duly executed and delivered hereunder. The provisions of this
Article VI are exclusive and shall preclude (to the extent lawful) all other
rights or remedies with respect to the replacement of mutilated, lost, stolen,
or destroyed Warrant Certificates.

                                  ARTICLE VII

                         RESERVATION AND AUTHORIZATION
                               OF COMMON SHARES

          The Company shall at all times reserve and keep available such number
of its authorized but unissued Common Shares deliverable upon exercise of the
Warrants as will be sufficient to permit the exercise in full of all outstanding
Warrants and will cause appropriate evidence of ownership of such Common Shares
to be delivered to the Warrant Agent upon its request for delivery thereof upon
the exercise of the Warrants. The Company covenants that all Common Shares of
the Company that may be issued upon the exercise of the Warrants will, upon
issuance, be duly authorized, validly issued, fully paid and not subject to any
calls for funds and free from pre-emptive rights and all taxes, liens, charges
and security interests with respect to the issue thereof.

                                 ARTICLE VIII

               WARRANT TRANSFER BOOKS; RESTRICTIONS ON TRANSFER

          Section 8.1. Transfer and Exchange. The Warrant Certificates shall be
          -----------  ---------------------
issued in registered form only. The Warrant Agent shall keep at its office a
register for the registration of Warrant Certificates and transfers or exchanges
of Warrant Certificates as herein provided and other appropriate data as
determined by the Warrant Agent. The Company shall, upon
<PAGE>

                                       23

reasonable notice to the Warrant Agent, have access to such register during the
Warrant Agent's regular business hours. All Warrant Certificates issued upon any
registration of transfer or exchange of Warrant Certificates shall be the valid
obligations of the Company, evidencing the same obligations, and entitled to the
same benefits under this Agreement, as the Warrant Certificates surrendered for
such registration of transfer or exchange.

          The Warrants shall initially be issued as part of the issuance of the
Units. Prior to the Separation Date, the Warrants may not be transferred or
exchanged separately from, but may be transferred or exchanged only together
with, the Notes issued as part of such Units.

          A Holder may transfer its Warrants only by written application to the
Warrant Agent stating the name of the proposed transferee and otherwise
complying with the terms of this Agreement. No such transfer shall be effected
until, and such transferee shall succeed to the rights of a Holder only upon,
final acceptance and registration of the transfer by the Warrant Agent in the
register. Prior to the registration of any transfer of Warrants by a Holder as
provided herein, the Company, the Warrant Agent, and any agent of the Company
may treat the person in whose name the Warrants are registered as the owner
thereof for all purposes and as the person entitled to exercise the rights
represented thereby, any notice to the contrary notwithstanding. Furthermore,
any holder of a Restricted Global Warrant shall, by acceptance of such
Restricted Global Warrant, agree that transfers of beneficial interests in such
Warrant may be effected only through a book-entry system maintained by the
holder of such Restricted Global Warrant (or its agent), and that ownership of a
beneficial interest in the Warrants represented thereby shall be required to be
reflected in a book-entry. When Warrant Certificates are presented to the
Warrant Agent with a request to register the transfer or to exchange them for an
equal amount of Warrants, the Warrant Agent shall register such transfer or make
such exchange as requested if its requirements for such transactions are met. To
permit registrations of transfers and exchanges, the Company shall execute
Warrant Certificates at the Warrant Agent's request. No service charge shall be
made for any registration of transfer or exchange of Warrants, but the Company
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer of
Warrants.

          Section 8.2. Book-Entry Provisions for the Restricted Global Warrants.
          -----------  --------------------------------------------------------
(a) The Restricted Global Warrants initially shall (i) be registered in the name
of the Depositary for such Restricted Global Warrant or the nominee of such
Depositary, (ii) be delivered to the Warrant Agent as custodian for such
Depositary and (iii) bear legends as set forth in Section 2.2 hereof.

          Members of, or participants in, the Depositary ("Agent Members") shall

have no rights under this Agreement with respect to the Restricted Global
Warrants held on their behalf by the Depositary or the Warrant Agent as its
custodian, and the Depositary may be treated by the Company, the Warrant Agent
and any agent of the Company or the Warrant Agent as the absolute owner of each
such Restricted Global Warrant for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Warrant Agent or
<PAGE>

                                       24

any agent of the Company or the Warrant Agent, from giving effect to any written
certification, proxy or other authorization furnished by the Depositary or

customary practices governing the exercise of the rights of a Holder of any
Warrants.

          (b)  Transfers of a Restricted Global Warrant shall be limited to
transfers of such Restricted Global Warrant in whole, but not in part, to the
Depositary, its successors or their respective nominees. Interests of beneficial
owners in the Restricted Global Warrants may be transferred in accordance with
the rules and procedures of the Depositary and the provisions of Section 8.3
hereof. Certificated Warrants shall be transferred to beneficial owners in
exchange for their beneficial interests in the Restricted Global Warrant, (i) if
the Depositary notifies the Company that it is unwilling or unable to continue
as Depositary for the Restricted Global Warrant and a successor depositary is
not appointed by the Company within 90 days of such notice, (ii) if there is a
Default or (iii) upon the request of the beneficial owner in accordance with the
rules and procedures of the Depositary and the provisions of Section 8.3 hereof.

          (c)  In connection with the transfer of the entire Restricted Global
Warrant to beneficial owners pursuant to paragraph (b) of this Section 8.2, the
Restricted Global Warrant shall be surrendered to the Warrant Agent for
cancellation, and the Company shall execute, and the Warrant Agent shall
countersign and deliver, to each beneficial owner identified by the Depositary
in exchange for its beneficial interest in the Restricted Global Warrant
Certificated Warrants, representing, in the aggregate, the number of Warrants
theretofore represented by the Restricted Global Warrant.

          (d)  In connection with the transfer of a portion of the beneficial
interests in the Restricted Global Warrant to beneficial owners pursuant to
paragraph (b) of this Section 8.2, the Warrant Agent shall reflect on its books
and records the date and a decrease in the amount of Warrants represented by the
Restricted Global Warrant in an amount equal to the amount of Warrants
represented by the beneficial interest in the Restricted Global Warrant to be
transferred, and the Company shall execute, and the Warrant Agent shall
countersign and deliver, to each beneficial owner identified by the Depositary
in exchange for its beneficial interest in the Restricted Global Warrant,
Certificated Warrants or of like tenor and amount.

          (e)  Any  Certificated  Warrant  delivered  in exchange  for an
interest in a Restricted Global Warrant pursuant to paragraph (b) or (d) of this
Section  shall,  except as otherwise  provided by  paragraph  (c) of Section 8.3
hereof, bear the legend regarding transfer restrictions set forth in Section 2.2
hereof.

          (f)  The registered holder of a Restricted Global Warrant may grant
proxies and otherwise authorize any person, including Agent Members and persons
that may hold
<PAGE>

                                       25

interests through Agent Members, to take any action which a Holder is entitled
to take under this Agreement or the Warrants.

          Section 8.3. Special Transfer Provisions. The following provisions
          -----------  ---------------------------
shall apply:

          (a)  Transfers to QIBs. The following provisions shall apply with
               -----------------
     respect to the registration of any proposed transfer of Warrants to a QIB:

               (i)  Following the Rule 144A Availability Date, if the Warrants
          to be transferred are represented by Certificated Warrants, the
          Warrant Agent shall register the transfer if such transfer is being
          made by a proposed transferor who has checked the box provided for on
          the form of Warrant Certificate stating, or has otherwise advised the
          Company and the Warrant Agent in writing, that the sale has been made
          in compliance with the provisions of Rule 144A to a transferee who has
          signed the certification provided for on the form of Warrant
          Certificate stating, or has otherwise advised the Company and the
          Warrant Agent in writing, that it is purchasing the Warrants for its
          own account or an account with respect to which it exercises sole
          investment discretion and that it and any such account is a QIB within
          the meaning of Rule 144A, and is aware that the sale to it is being
          made in reliance on Rule 144A and acknowledges that it has received
          such information regarding the Company as it has requested pursuant to
          Rule 144A or has determined not to request such information and that
          it is aware that the transferor is relying upon its foregoing
          representations in order to claim the exemption from registration
          provided by Rule 144A.

               (ii) If the proposed transferee is an Agent Member, upon receipt
          by the Warrant Agent of the documents referred to in clause (i) above
          and instructions given in accordance with the Depositary's and the
          Warrant Agent's procedures, the Warrant Agent shall reflect on its
          books and records the date and an increase in the amount of Warrants
          represented by the Restricted Global Warrant in an amount equal to the
          amount of Warrants represented by the Certificated Warrants to be
          transferred, and the Warrant Agent shall cancel the Certificated
          Warrants.

          (b)  Transfers to Institutional Accredited Investor. The following
               ----------------------------------------------
     provisions shall apply with respect to the registration of any proposed
     transfer of Warrants to any Person not specified in paragraphs (a) above.

               (i)  The Warrant Agent shall register any proposed transfer of
          Warrants to any such Person if (x) the transferor has delivered to the
          Warrant Agent and the Company a certificate substantially in the form
          of Exhibit B-1 hereto and, if required by paragraph (d) thereof, an
          Opinion of Counsel to the effect set forth therein and (y) the
          proposed transferee has delivered to the
<PAGE>

                                       26

          Warrant Agent and the Company a certificate substantially in the form
          of Exhibit B-2 hereto.

               (ii) If the proposed transferor is an Agent Member holding a
          beneficial interest in the Restricted Global Warrant, upon receipt by
          the Warrant Agent and the Company of the documents referred to in
          clause (i) above and instructions given in accordance with the
          Depositary's and the Warrant Agent's procedures, the Company shall
          execute and the Warrant Agent shall countersign Certificated Warrants
          in an amount equal to the number of Warrants represented by the
          Restricted Global Warrant, to be transferred and the Warrant Agent
          shall decrease the number of Warrants represented by the Restricted
          Global Warrant so transferred.

          (c)  Private Placement Legend. Upon the transfer, exchange or
               ------------------------
     replacement of Warrant Certificates not bearing the Private Placement
     Legend, the Warrant Agent shall make available for delivery Warrant
     Certificates that do not bear the Private Placement Legend. Upon the
     transfer, exchange or replacement of Warrant Certificates bearing the
     Private Placement Legend, the Warrant Agent shall make available for
     delivery only Warrant Certificates that bear the Private Placement Legend
     unless there is delivered to the Warrant Agent an opinion of counsel
     reasonably satisfactory to the Company and its counsel and the Warrant
     Agent to the effect that neither such legend nor the related restrictions
     on transfer are required in order to maintain compliance with the
     provisions of the Securities Act.

          (d)  General. (i) By its acceptance of any Warrants represented by a
               -------
     Warrant Certificate bearing the Private Placement Legend, each Holder of
     such Warrants acknowledges the restrictions on transfer of such Warrants
     set forth in this Agreement and in the Private Placement Legend and agrees
     that it will transfer such Warrants only as provided in this Agreement. The
     Warrant Agent shall not register a transfer of any Warrants unless such
     transfer complies with the restrictions on transfer of such Warrants set
     forth in this Agreement and is in compliance with applicable laws and
     applicable rules, regulations and procedures of any securities exchange or
     clearing agency in effect from time to time. In connection with any
     transfer of Warrants, each Holder agrees by its acceptance of Warrants to
     furnish the Warrant Agent or the Company such certifications, legal
     opinions or other information as either of them may reasonably require to
     confirm that such transfer is being made pursuant to an exemption from, or
     a transaction not subject to, the registration requirements of the
     Securities Act or any other applicable laws of any foreign jurisdiction;
     provided that the Warrant Agent shall not be required to determine (but may
     rely on a determination made by the Company with respect to) the
     sufficiency of any such certifications, legal opinions or other
     information.
<PAGE>

                                       27

          (ii) The Warrant Agent shall retain copies of all letters, notices and
     other written communications received pursuant to Section 8.2 hereof or
     this Section 8.3. The Company shall have the right to inspect and make
     copies of all such letters, notices or other written communications at any
     reasonable time upon the giving of reasonable written notice to the Warrant
     Agent.

          Section 8.4. Surrender of Warrant Certificates. Any Warrant
          -----------  ---------------------------------
Certificate surrendered for registration of transfer, exchange or exercise of
the Warrants represented thereby shall, if surrendered to the Company, be
delivered to the Warrant Agent, and all Warrant Certificates surrendered or so
delivered to the Warrant Agent shall be promptly cancelled by the Warrant Agent
and shall not be reissued by the Company and, except as provided in this Article
VIII in case of an exchange, Article III hereof in case of the exercise of less
than all the Warrants represented thereby or Article VI in case of a mutilated
Warrant Certificate, no Warrant Certificate shall be issued hereunder in lieu
thereof. The Warrant Agent shall deliver to the Company from time to time or
otherwise dispose of such cancelled Warrant Certificates as the Company may
direct in writing.

                                  ARTICLE IX

                                WARRANT HOLDERS

          Section 9.1. Warrant Holder Deemed Not a Stockholder. The Company and
          -----------  ---------------------------------------
the Warrant Agent may deem and treat the registered Holder(s) of the Warrant
Certificates as the absolute owner(s) thereof (notwithstanding any notation of
ownership or other writing thereon made by anyone), for the purpose of any
exercise thereof and for all other purposes, and neither the Company nor the
Warrant Agent shall be affected by any notice to the contrary. Accordingly, the
Company and/or the Warrant Agent shall not, except as ordered by a court of
competent jurisdiction as required by law, be bound to recognize any equitable
or other claim to or interest in the Warrants on the part of any person other
than such registered Holder, whether or not it shall have express or other
notice thereof. Prior to the valid exercise of the Warrants, no Holder of a
Warrant Certificate, as such, shall be entitled to any rights of a stockholder
of the Company, including, without limitation, the right to vote or to consent
to any action of the stockholders, to receive dividends or other distributions,
to exercise any preemptive right or to receive any notice of meetings of
stockholders and, except as otherwise provided in this Agreement, shall not be
entitled to receive any notice of any proceedings of the Company.

          Section 9.2. Right of Action. All rights of action with respect to
          -----------  ---------------
this Agreement are vested in the Holders of the Warrants, and any Holder of any
Warrant, without the consent of the Warrant Agent or the Holders of any other
Warrant, may, on such Holder's own behalf and for such Holder's own benefit,
enforce, and may institute and maintain any suit, action or proceeding against
the Company suitable to enforce, or otherwise in respect of, such Holder's
<PAGE>

                                       28

right to exercise such Warrants in the manner provided in the Warrant
Certificate representing such Warrants and in this Agreement.

                                   ARTICLE X

                                   REMEDIES

          Section 10.1. Defaults. It shall be deemed to be a "Default" with
          ------------  --------                              -------
respect to the Company's (or its successor's) obligations under this Agreement
if:

          (a)  a Repurchase Event occurs and the Company (or its successor)
     shall fail to make a Repurchase Offer pursuant to Section 3.4 hereof; or

          (b)  the Company (or its successor) shall fail to purchase the
     Warrants pursuant to the Repurchase Offer in accordance with the provisions
     of Section 3.4 hereof.

          Section 10.2. Payment Obligations. Upon the happening of a Default
          ------------  -------------------
under this Agreement, the Company shall be obligated to increase the amount
otherwise payable pursuant to Section 3.4(d) hereof in respect of the Repurchase
Offer to which such Default relates by an amount equal to interest thereon at a
rate per annum equal to 13% from the date of the Default to the date of payment,
which interest shall compound quarterly (all such payment obligations in respect
of such Repurchase Offer, together with all such increased amounts, being the
"Repurchase Obligation").
 ---------------------

          Section 10.3. Remedies; No Waiver. Notwithstanding any other provision
          ------------  -------------------
of this Warrant Agreement, if a Default occurs and is continuing, the Holders of
the Warrants may pursue any available remedy to collect the Repurchase
Obligation or to enforce the performance of any provision of this Warrant
Agreement. A delay or omission by any Holder of a Warrant in exercising, or a
failure to exercise, any right or remedy arising out of a Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Default. All remedies are cumulative to the extent permitted by law.

                                  ARTICLE XI

                               THE WARRANT AGENT

          Section 11.1. Duties and Liabilities. The Warrant Agent hereby accepts
          ------------  ----------------------
the agency established by this Agreement and agrees to perform the same upon the
terms and conditions herein set forth, by all of which the Company and the
Holders of Warrants, by their acceptance thereof, shall be bound. The Warrant
Agent shall not, by countersigning Warrant
<PAGE>

                                       29

Certificates or by any other act hereunder, be deemed to make any
representations as to the validity or authorization of the Warrants or the
Warrant Certificates (except as to its countersignature thereon) or of any
Common Shares issued upon exercise of any Warrant, or as to the accuracy of the
computation of the Exercise Price or the number or kind or amount of Common
Shares deliverable upon exercise of any Warrant or the correctness of the
representations of the Company made in the certificates that the Warrant Agent
receives. The Warrant Agent shall not be accountable for the use or application
by the Company of the proceeds of the exercise of any Warrant. The Warrant Agent
shall not have any duty to calculate or determine any adjustments with respect
to either the Exercise Price or the kind and amount of Common Shares receivable
by Holders upon the exercise of Warrants required from time to time and the
Warrant Agent shall have no duty or responsibility in determining the accuracy
or correctness of such calculation. The Warrant Agent shall not be (a) liable
for any recital or statement of fact contained herein or in the Warrant
Certificates or for any action taken, suffered or omitted by it in good faith
without gross negligence in the belief that any Warrant Certificate or any other
documents or any signatures are genuine or properly authorized, (b) responsible
for any failure on the part of the Company to comply with any of its covenants
and obligations contained in this Agreement or in the Warrant Certificates or
(c) liable for any act or omission in connection with this Agreement except for
its own gross negligence, bad faith or willful misconduct. In no event shall the
Warrant Agent be liable for consequential damages. The Warrant Agent is hereby
authorized to accept instructions with respect to the performance of its duties
hereunder from the Chairman of the Board, Chief Executive Officer, any Vice
President or other executive officer of the Company and to apply to any such
officer for instructions (which instructions will be promptly given in writing
when requested) and the Warrant Agent shall not be liable for any action taken
or suffered to be taken by it in good faith without gross negligence in
accordance with the instructions of any such officer; provided, however, that,
in its discretion, the Warrant Agent may, in lieu thereof, accept other evidence
of such or may require such further or additional evidence as it may deem
reasonable. The Warrant Agent shall not be liable for any action taken with
respect to any matter in the event it requests instructions from the Company as
to that matter and does not receive such instructions within a reasonable period
of time after the request therefor.

          The Warrant Agent may execute and exercise any of the rights and
powers hereby vested in it or perform any duty hereunder either itself or by or
through attorneys, agents or employees of its selection, and the Warrant Agent
shall not be answerable or accountable for any act, default, neglect or
misconduct of any such attorneys, agents or employees; provided that reasonable
care has been exercised with respect to the retention of any such attorney,
agent or employee. The Warrant Agent shall not be under any obligation or duty
to institute, appear in or defend any action, suit or legal proceeding in
respect hereof, unless first indemnified to its reasonable satisfaction. The
Warrant Agent shall promptly notify the Company in writing of any claim made or
action, suit or proceeding instituted against it arising out of or in connection
with this Agreement.
<PAGE>

                                       30

          The Company will perform, execute, acknowledge and deliver or cause to
be delivered all such further acts, instruments and assurances as are consistent
with this Agreement and as may reasonably be required by the Warrant Agent in
order to enable it to carry out or perform its duties under this Agreement.

          The Warrant Agent shall act solely as agent of the Company hereunder.
The Warrant Agent shall not be liable except for the failure to perform such
duties as are specifically set forth herein, and no implied covenants or
obligations shall be read into this Agreement against the Warrant Agent, whose
duties and obligations shall be determined solely by the express provisions
hereof.

          Section 11.2. Right to Consult Counsel. The Warrant Agent may at any
          ------------  ------------------------
time consult with legal counsel of its selection (who may be legal counsel for
the Company), and the written opinion or advice of such counsel shall be full
and complete authorization and protection to the Warrant Agent and the Warrant
Agent shall incur no liability or responsibility to the Company or to any Holder
for any action taken, suffered or omitted by it in good faith without gross
negligence in accordance with the written opinion or advice of such counsel.

          Section 11.3. Compensation; Indemnification. The Company agrees
          ------------  -----------------------------
promptly to pay the Warrant Agent from time to time and in any case within 30
days of receipt of an invoice, compensation for its services hereunder as the
Company and the Warrant Agent may agree from time to time, and to reimburse it
upon its request upon furnishing reasonable supporting documentation for fees or
expenses and reasonable counsel fees and expenses incurred in connection with
the execution and administration of this Agreement, and further agrees to
indemnify each of the Warrant Agent and any predecessor Warrant Agent and save
it harmless against any and all losses, claims, damages, liabilities or
reasonable expenses arising out of or in connection with the acceptance and
administration of this Agreement, including, without limitation, the reasonable
costs and expenses of investigating or defending any claim of such liability,
except that the Company shall have no liability hereunder to the extent that any
such loss, liability or expense results from the Warrant Agent's own gross
negligence, bad faith or willful misconduct. The obligations of the Company
under this Section 11.3 shall survive the exercise and the expiration of the
Warrants, the termination of this Agreement and the resignation or removal of
the Warrant Agent in respect of services or expenses incurred in connection with
the Warrants or this Agreement.

          Section 11.4. No Restrictions on Actions. Nothing in this Agreement
          ------------  --------------------------
shall be deemed to prevent the Warrant Agent and any stockholder, director,
officer or employee of the Warrant Agent from buying, selling or dealing in any
of the Warrants or other securities of the Company or becoming pecuniarily
interested in transactions in which the Company may be interested, or
contracting with or lending money to the Company or otherwise acting as fully
and freely as though it were not the Warrant Agent under this Agreement. Nothing
herein shall
<PAGE>

                                       31

preclude the Warrant Agent from acting in any other capacity for the Company or
for any other legal entity.

               Section 11.5. Discharge or Removal; Replacement Warrant Agent.
               ------------  -----------------------------------------------
The Warrant Agent may resign from its position as such and be discharged from
all further duties and liabilities hereunder (except liability arising as a
result of the Warrant Agent's own gross negligence, bad faith or willful
misconduct), after giving one month's prior written notice to the Company. The
Company may at any time remove the Warrant Agent upon one month's written notice
specifying the date when such discharge shall take effect, and the Warrant Agent
shall thereupon in like manner be discharged from all further duties and
liabilities hereunder, except as aforesaid. The Warrant Agent shall mail to each
Holder of a Warrant, at the Company's expense, a copy of said notice of
resignation or notice of removal, as the case may be. Upon such resignation or
removal the Company shall appoint in writing a new warrant agent. If the Company
shall fail to make such appointment within a period of 30 days after it has been
notified in writing of such resignation by the resigning Warrant Agent or after
such removal, then the resigning or removed Warrant Agent or the Holder of any
Warrant may, at the expense of the Company, apply to any court of competent
jurisdiction for the appointment of a new warrant agent. After 30 days from
receipt of, or giving, notice, as the case may be, and pending appointment of a
successor to the original Warrant Agent, either by the Company or by such a
court, the duties of the Warrant Agent shall be carried out by the Company. Any
new warrant agent, whether appointed by the Company or by such a court, shall be
a bank or trust company doing business under the laws of the United States or
any state thereof, in good standing and having (or, in the case of a subsidiary
of a bank holding company, its parent having) a combined capital and surplus of
not less than $25,000,000. The combined capital and surplus of any such new
warrant agent shall be deemed to be the combined capital and surplus as set
forth in the most recent annual report of its condition published by such
warrant agent (or parent) prior to its appointment, provided that such reports
are published at least annually pursuant to law or to the requirements of a
federal or state supervising or examining authority. After acceptance in writing
of such appointment by the new warrant agent, it shall be vested with the same
powers, rights, duties and responsibilities as if it had been originally named
herein as the Warrant Agent, without any further assurance, conveyance, act or
deed; however, the original Warrant Agent shall in all events deliver and
transfer to the successor Warrant Agent all property (including, without
limitation, documents and recorded information), if any, at the time held
hereunder by the original Warrant Agent and if for any reason it shall be
necessary or expedient to execute and deliver any further assurance, conveyance,
act or deed, the same shall be done at the expense of the Company and shall be
legally and validly executed and delivered by the resigning or removed Warrant
Agent. Not later than the effective date of any such appointment, the Company
shall file notice thereof with the resigning or removed Warrant Agent and shall
forthwith cause a copy of such notice to be mailed by the successor Warrant
Agent to each Holder of a Warrant. Failure to give any notice provided for in
this Section 11.5, however, or any defect therein, shall not affect the legality
or validity of the resignation of the Warrant Agent or the appointment of a new
<PAGE>

                                       32

warrant agent, as the case may be. No Warrant Agent hereunder shall be liable
for any acts or omissions of any successor Warrant Agent.

               Section 11.6. Successor Warrant Agent. Any corporation into which
               ------------  -----------------------
the Warrant Agent or any new warrant agent may be merged or converted, or any
corporation resulting from any consolidation to which the Warrant Agent or any
new warrant agent shall be a party or any corporation succeeding to all or
substantially all the corporate trust business of the Warrant Agent (including
the administration of this Agreement), shall be a successor Warrant Agent under
this Agreement without any further act, provided that such corporation would be
eligible for appointment as successor to the Warrant Agent under the provisions
of Section 11.5 hereof. Any such successor Warrant Agent shall promptly cause
notice of its succession as Warrant Agent to be mailed to each Holder of a
Warrant.

                                  ARTICLE XII

                                 MISCELLANEOUS

               Section 12.1. Market Stand-off Agreement. Each Holder hereby
               ------------  --------------------------
agrees that such Holder shall not sell, transfer, make any short sale of, grant
any option for the purchase of, or enter into any hedging or similar transaction
with the same economic effect as a sale of any Warrants or Common Stock of the
Company held by such Holder (other than those included in the registration) for
a period specified by the representative of the underwriters of Common Stock of
the Company not to exceed one hundred eighty (180) days following the effective
date of a registration statement of the Company filed under the Securities Act;
provided that:

               (i)   such agreement shall apply only to the Company's first firm
          commitment underwritten public offering of its Common Stock registered
          under the Securities Act, which is either the subject of a firm
          underwriting commitment or an on-line offering pursuant to the Dutch
          auction process (the "Initial Offering");
                                ----------------

               (ii)  all officers and directors of the Company who hold capital
          stock or rights to acquire capital stock of the Company and greater
          than five percent (5%) stockholders of the Company enter into similar
          agreements; and

               (iii) such agreement shall not apply to any shares of Common
          Stock (or other securities) purchased in the Initial Offering or
          purchased in the open market following the Initial Offering.

               Each Holder agrees to execute and deliver such other agreements
as may be reasonably requested by the Company or the underwriter which are

<PAGE>

                                       33

the representative of the underwriters of Common Stock (or other securities) of
the Company, each Holder shall provide, within ten (10) days of such request,
such information as may be required by the Company or such representative in
connection with the completion of any public offering of the Company's
securities pursuant to a registration statement filed under the Securities Act.
The obligations described in this Section 12.1 shall not apply to a registration
relating solely to employee benefit plans on Form S-1 or Form S-8 or similar
forms that may be promulgated in the future, or a registration relating solely
to a Rule 145 transaction on Form S-4 or similar forms that may be promulgated
in the future. The Company may impose stop-transfer instructions with respect to
the Warrants or shares of Common Stock subject to the foregoing restriction
until the end of said one hundred eighty (180) day period.

               Section 12.2. Monies Deposited with the Warrant Agent. The
               ------------  ---------------------------------------
Warrant Agent shall not be required to pay interest on any monies deposited
pursuant to the provisions of this Agreement except such as it shall agree in
writing with the Company to pay thereon. Any monies, securities or other
property which at any time shall be deposited by the Company or on its behalf
with the Warrant Agent pursuant to this Agreement shall be and are hereby
assigned, transferred and set over to the Warrant Agent in trust for the purpose
for which such monies, securities or other property shall have been deposited;
but such monies, securities or other property need not be segregated from other
funds, securities or other property except to the extent required by law. Any
monies, securities or other property deposited with the Warrant Agent for
payment or distribution to the Holders that remains unclaimed for one year after
the date the monies, securities or other property was deposited with the Warrant
Agent shall be delivered to the Company upon its request therefor.

               Section 12.3. Payment of Taxes. Subject to Article VI hereof, all
               ------------  ----------------
Common Shares issuable upon the exercise of Warrants shall be validly issued,
fully paid and nonassessable, and the Company shall pay any taxes and other
governmental charges that may be imposed under the laws of the United States of
America or any political subdivision or taxing authority thereof or therein in
respect of the issue or delivery thereof upon exercise of Warrants (other than
income taxes imposed on the Holders). The Company shall not be required,
however, to pay any tax or other charge imposed in connection with any transfer
involved in the issue of any certificate for Common Shares (including other
securities or property issuable upon the exercise of the Warrants) or payment of
cash to any Person other than the Holder of a Warrant Certificate surrendered
upon the exercise of a Warrant and in case of such transfer or payment, the
Warrant Agent and the Company shall not be required to issue any share
certificate or pay any cash until such tax or charge has been paid or it has
been established to the Warrant Agent's and the Company's satisfaction that no
such tax or charge is due.

               Section 12.4. No Merger, Consolidation or Sale of Assets of the
               ------------  -------------------------------------------------
Company. Except as otherwise provided herein, the Company will not merge into or

consolidate with any other Person, or sell or otherwise transfer its property,
assets and business substantially as an entirety to a successor of the Company,
unless the Person resulting from such merger or
<PAGE>

consolidation, or such successor of the Company, shall expressly assume, by
supplemental agreement satisfactory in form to the Warrant Agent and executed
and delivered to the Warrant Agent, the due and punctual performance and
observance of each and every covenant and condition of this Agreement or
contained in the Warrants to be performed and observed by the Company.

               Section 12.5. Reports to Holders. At all times from and after the

Agreement (the "Registration") and (ii) the date that is 24 months from the
                ------------
Closing Date, in either case, whether or not the Company is then required to

such reports and other information as it would be required to file with the
Commission by Sections 13(a) or 15(d) under the Securities Exchange Act of 1934
if it were subject thereto. The Company shall supply the Warrant Agent and each
Holder or shall supply to the Warrant Agent for forwarding to each such Holder,
without cost to such Holder, copies of such reports and other information. In
addition, at all times prior to the earlier of the date of the Registration and
the date that is 24 months from the Closing Date, the Company shall, at its
cost, deliver to each Holder of the Warrants quarterly and annual financial
statements substantially equivalent to those which would be included in reports
required to be filed under the Exchange Act. In addition, after the Rule 144A

Opinion of Counsel which provide all conditions precedent to adoption of an
amendment that have been satisfied.

               Section 12.11. Common Shares Legend. Unless and until the Common
               -------------  --------------------
Shares issuable upon the exercise of the Warrants are registered under the
Securities Act, or unless otherwise agreed by the Company and the Holder
thereof, such Common Shares will bear a legend substantially to the following
effect:

         THE COMMON SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
         "SECURITIES ACT"), AND ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED
         OR OTHERWISE TRANSFERRED WITHIN THE UNITED STATES OR TO, OR FOR THE
         ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE
         FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER (1)
         REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED
         IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL
         "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(a)(1), (2), (3) OR (7) OF
         REGULATION D UNDER THE SECURITIES ACT) (AN "INSTITUTIONAL ACCREDITED
         INVESTOR"), (2) AGREES THAT IT WILL NOT, WITHIN THE TIME PERIOD
         REFERRED TO UNDER RULE 144(k), UNDER THE SECURITIES ACT AS IN EFFECT
         WITH RESPECT TO SUCH TRANSFER, RESELL OR OTHERWISE TRANSFER THE COMMON
         SHARES REPRESENTED BY THIS CERTIFICATE EXCEPT (A) TO LOUDCLOUD, INC.
         (THE "COMPANY") OR ANY SUBSIDIARY THEREOF, (B) FOLLOWING THE RULE 144A
         AVAILABILITY DATE, TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE
         WITH RULE 144A UNDER THE SECURITIES ACT, (C) TO AN INSTITUTIONAL
         ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO THE
         TRANSFER AGENT AND REGISTRAR
<PAGE>

                                       37

         A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS
         RELATING TO THE RESTRICTIONS ON TRANSFER OF THE COMMON SHARES
         REPRESENTED BY THIS CERTIFICATE (THE FORM OF WHICH LETTER CAN BE
         OBTAINED FROM THE TRANSFER AGENT AND REGISTRAR) AND AN OPINION OF
         COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE
         WITH THE SECURITIES ACT, (D) PURSUANT TO THE EXEMPTION FROM
         REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF
         AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER
         THE SECURITIES ACT AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON
         TO WHOM THE COMMON SHARES REPRESENTED BY THIS CERTIFICATE ARE
         TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN
         CONNECTION WITH ANY TRANSFER OF THE COMMON SHARES REPRESENTED BY THIS
         CERTIFICATE WITHIN THE TIME PERIOD REFERRED TO ABOVE, THE HOLDER MUST
         CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO
         THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRANSFER
         AGENT AND REGISTRAR. IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL
         ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH
         TO EACH OF THE TRANSFER AGENT AND REGISTRAR AND THE COMPANY SUCH
         CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM
         MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE
         PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
         REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE
         TERMS "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM
         BY REGULATION S UNDER THE SECURITIES ACT. THE COMPANY HAS INSTRUCTED
         THE TRANSFER AGENT AND REGISTRAR TO REFUSE TO REGISTER ANY TRANSFER OF
         THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE IN VIOLATION
         OF THE FOREGOING RESTRICTIONS.

               Section 12.12. Third Party Beneficiaries. The Holders shall be
               -------------  -------------------------
third party beneficiaries to the agreements made hereunder between the Company,
on the one hand, and the Warrant Agent, on the other hand, and each Holder shall
have the right to enforce such agreements directly to the extent it deems such
enforcement necessary or advisable to protect its rights or the rights of
Holders hereunder. By acquiring Warrants, each Holder agrees to be bound by the
obligations of Holders generally as set forth herein and as such obligations may
be applicable to such Holder.

               -------------  -----------

anniversary of the Closing Date. Notwithstanding the foregoing, this Agreement
shall terminate on any earlier date as of which all Warrants have been

               Section 12.14. Governing Law. This Agreement shall be governed by
               -------------  -------------
the laws of the State of New York. The Warrant Agent, the Company and the
Holders agree to submit to the jurisdiction of the courts of the State of New
York in any action or proceeding arising out of or relating to this Agreement or
the Warrants.

                            RIGHTS OF PARTICIPATION

               Section 13.1. Subsequent Offerings. Each Holder who is an
               ------------  --------------------
"accredited investor" within the meaning of Rule 501(a) of the Securities Act
shall have a right of participation to purchase its pro rata share of all Equity
Securities, as defined below, that the Company may, from time to time, propose
to sell and issue after the date of this Agreement, other than the Equity
Securities excluded by Section 13.5 hereof. Each Holder's pro rata share is
equal to the ratio of (a) the number of shares of the Common Stock (including
all shares of Common Stock issued or issuable upon exercise of the Warrants) of
which such Holder is deemed to be a holder immediately prior to the issuance of
such Equity Securities to (b) the total number of shares of the Company's
outstanding Common Stock (including all shares of Common Stock issued or
issuable upon conversion of the Company's Series A Preferred Stock and Series B
Preferred Stock or upon the exercise of any outstanding warrants or options)
immediately prior to the issuance of the Equity Securities. The term "Equity
                                                                      ------
Securities" shall mean (i) any Common Stock, preferred stock or other security
----------
of the Company, (ii) any security convertible, with or without consideration,
into any Common Stock, preferred stock or other security (including any option
to purchase such a convertible security), (iii) any security carrying any
warrant or right to subscribe to or purchase any Common Stock, preferred stock
or other security or (iv) any such warrant or right.

               Section 13.2. Exercise of Rights. If the Company proposes to
               ------------  ------------------
issue any Equity Securities, it shall give each Holder written notice of its
intention, describing the Equity Securities, the price and the terms and
conditions upon which the Company proposes to issue the same. Each Holder shall
have fifteen (15) days from the giving of such notice to agree to purchase its
pro rata share of the Equity Securities for the price and upon the terms and
conditions specified in the notice by giving written notice to the Company and
stating therein the quantity of Equity Securities to be purchased.
Notwithstanding the foregoing, the Company shall not be required to offer or
sell such Equity Securities to any Holder who would cause the Company to be in
violation of applicable federal securities laws by virtue of such offer or sale.

               Section 13.3. Issuance of Equity Securities to Other Persons. If
               ------------  ----------------------------------------------
not all of the Holders elect to purchase their pro rata share of the Equity
Securities, then the Company shall promptly notify in writing the Holders who do
so elect and shall offer such Holders the right to acquire such unsubscribed
shares. The Holders shall have five (5) days after receipt of such notice to
notify the Company of its election to purchase all or a portion thereof of the
unsubscribed shares. If the Holders fail to exercise in full the rights of first
refusal, the Company shall have ninety (90) days thereafter to sell the Equity
Securities in respect of which the Holder's rights were not exercised, at a
price and upon general terms and conditions materially no more favorable to the
purchasers thereof than specified in the Company's notice to the Investors
pursuant to Section 13.2 hereof. If the Company has not sold such Equity
Securities within ninety (90) days of the notice provided pursuant to Section
13.2, the Company shall not thereafter issue or sell any Equity Securities,
without first offering such securities to the Holders in the manner provided
above.

               Section 13.4. Termination of Rights of Participation. The rights
               ------------  --------------------------------------
of participation established by this Article XIII shall not apply to, and shall
terminate upon the earlier of (i) the effective date of the registration
statement pertaining to the Company's Qualified Offering and (ii) a Change in
Control. The term "Qualified Public Offering" shall mean a firmly underwritten
                   -------------------------
public offering of shares of Common Stock for a total offering of not less than
$20 million (before deduction of underwriters' commissions and expenses). The
term "Change in Control" shall mean (A) the acquisition of the Company by
      -----------------
another entity by means of any transaction or series of related transactions
(including, without limitation, any reorganization, merger or consolidation)
that results in the transfer of fifty percent (50%) or more of the outstanding
voting power of the Company or (B) a sale of all or substantially all of the
assets of the Company.

               Section 13.5. Excluded Securities. The rights of participation
               ------------  -------------------
established by this Article XIII shall have no application to any of the
following Equity Securities:

               (a)  any Equity Securities issued or to be issued to employees,
         officers or directors of, or consultants or advisors to the Company or
         any subsidiary, pursuant to stock purchase or stock option plans or
         other arrangements that are approved by the Board of Directors;

               (b)  any Equity Securities issued pursuant to any rights,
         agreements, options and warrants outstanding or issued as of the date
         of this Agreement; and any Equity Securities issued pursuant to any
         rights, agreements, options or warrants granted after the date of this
         Agreement; provided that either the rights of participation established
         by this Article XIII applied with respect to the initial sale or grant
         by the Company of such rights, agreements, options or warrants or such
         rights, agreements, options or warrants constituted Excluded Securities
         pursuant to this Section 13.5 at the time of issuance;

                                       40

               (c)  any Equity Securities issued for consideration other than
         cash pursuant to a merger, consolidation, acquisition or similar

               (d)  any Equity Securities issued in connection with any stock
         split, stock dividend or recapitalization by the Company;

         Company's Series A Preferred Stock and Series B Preferred Stock;

               (f)  any Equity Securities issued pursuant to any equipment
         leasing arrangement, real estate transaction or commercial credit
         arrangement from a bank or similar financial institution or any Equity
         Securities issued as part of a unit including debt of the Company or
         its subsidiaries and in each case such issuances are primarily for
         other than non-equity financing purposes;

               (g)  any Equity Securities that are issued by the Company
         pursuant to a registration statement filed under the Securities Act;

               (h)  any Equity Securities issued in connection with strategic
         transactions that include a commercial relationship involving the
         Company and other entities, including (i) joint ventures,
         manufacturing, marketing or distribution arrangements or (ii)
         technology transfer or development arrangements; provided that such
         strategic transactions and the issuance of Equity Securities pursuant
         thereto has been approved by the Company's Board of Directors; and

               (i)  any Equity Securities issued in a transaction in which the
         consideration received by the Company is determined by the
         disinterested members of the Board to be at least equal to the fair
         market value of the Equity Securities.

               IN WITNESS WHEREOF, the parties have caused this Agreement to be
duly executed, as of the day and year first above written.

               State Street Bank and Trust Company of California, N.A.
               633 West 5/th/ Street, 12/th/ Floor

               A "Repurchase Event", as defined in the Warrant Agreement, shall
                  ----------------
be deemed to occur on any date when the Company (i) consolidates with or merges
into or with another person (but only where the holders of Common Stock receive
consideration in exchange for all or part of such Common Stock), if the Common
Stock (or other securities) thereafter issuable upon exercise of the Warrants is
not registered under the Exchange Act or (ii) sells all or substantially all of
its assets to another person, if the Common Stock (or other securities)
thereafter issuable upon exercise of the Warrants is not registered under the
Exchange Act; provided that, in each case, a "Repurchase Event" shall not be
deemed to have occurred if the consideration for such transaction consists
solely of cash.

               Following a Repurchase Event, the Company must make an offer to
repurchase for cash all outstanding Warrants (a "Repurchase Offer"). If the
                                                 ----------------
Company makes a Repurchase Offer, Holders may, until the expiration date of such
offer, surrender all or part of their Warrants for repurchase by the Company.

               Warrants received by the Warrant Agent in proper form during a
Repurchase Offer will, except as otherwise provided in the Warrant Agreement, be
repurchased by the Company at a price in cash (the "Repurchase Price") equal to
                                                    ----------------
the value on the Valuation Date relating thereto of the Common Shares issuable,
and other securities or property of the Company which would have been delivered
upon exercise of the Warrants had the Warrants been exercised (whether or not
the Warrants are then exercisable), less the Exercise Price in effect on the
Notice Date for such Repurchase Offer. The value of such Common Shares and other
securities will be (i) if the Common Shares (or other securities) are registered
under the Exchange Act, determined based upon the average of the daily market
prices (as determined pursuant to Section 3.4(d)(ii)(1) of the Warrant
Agreement) of the Common Shares (or other securities) for the 20
<PAGE>

                                      A-3

consecutive trading days immediately preceding such Valuation Date or (ii) if
the Common Shares (or other securities) are not registered under the Exchange
Act or if the value cannot be computed under clause (i) above, determined by the
Independent Financial Expert (as defined in the Warrant Agreement), in each case
as set forth in the Warrant Agreement.

               The "Valuation Date" as defined in the Warrant Agreement shall be
                    --------------
deemed to occur on the date five Business Days prior to the date notice of the
Repurchase Offer is first given.

               If the Company fails to make or complete a Repurchase Offer (a
"Default") as required by the Warrant Agreement, it shall be obligated to
 -------
increase the amount otherwise payable pursuant to the Warrant Agreement in
respect of the Repurchase Offer by an amount equal to interest thereon at a rate
per annum of 13% from the date of the Default to the date of payment, which
interest shall compound quarterly.

               If the Company merges or consolidates with or into, or sells all
or substantially all of its property and assets to, another Person and the
consideration received by holders of Common Shares consists solely of cash, the
Holders of Warrants shall be entitled to receive distributions on the date of
such event on an equal basis with holders of Common Shares (or other securities
issuable upon exercise of the Warrants) as if the Warrants had been exercised
immediately prior to such event (less the Exercise Price). Upon receipt of such
payment, if any, the rights of a Holder shall terminate and cease and such
Holder's Warrants shall expire.

               The number of Common Shares purchasable upon the exercise of each
Warrant and the price per share are subject to adjustment as provided in the
Warrant Agreement. Except as stated in the immediately preceding paragraph and
in the Warrant Agreement, in the event the Company merges or consolidates with,
or sells all or substantially all of its assets to, another Person, each Warrant
will, upon exercise, entitle the Holder thereof to receive the number of shares
of capital stock or other securities or the amount of money and other property
which the holder of a Common Share (or other securities or property issuable
upon exercise of a Warrant) is entitled to receive upon completion of such
merger, consolidation or sale.

               As to any final fraction of a share which the same Holder of one
or more Warrant Certificates would otherwise be entitled to purchase upon
exercise thereof in the same transaction, the Company may pay the cash value
thereof determined as provided in the Warrant Agreement.

               Subject to Article VI of the Warrant Agreement, all Common Shares
issuable by the Company upon the exercise of Warrants shall be validly issued,
fully paid and not subject to any calls for funds, and the Company shall pay any
taxes and other governmental charges that may be imposed under the laws of the
United States of America or any political subdivision or taxing authority
thereof or therein in respect of the issue or delivery thereof upon exercise of
<PAGE>

Warrants (other than income taxes imposed on the Holders). The Company shall not
be required, however, to pay any tax or other charge imposed in connection with
any transfer involved in the issue of any certificate for Common Shares
(including other securities or property issuable upon the exercise of
the Warrants) or payment of cash to any Person other than the Holder of a
Warrant Certificate surrendered upon the exercise of a Warrant and in case of
such transfer or payment, the Warrant Agent and the Company shall not be
required to issue any share certificate or pay any cash until such tax or charge
has been paid or it has been established to the Warrant Agent's and the
Company's satisfaction that no such tax or charge is due.

               Subject to the restrictions on and conditions to transfer set
forth in Articles II and VIII of the Warrant Agreement, this Warrant Certificate
and all rights hereunder are transferable by the registered Holder hereof, in
whole or in part, on the register of the Company maintained by the Warrant Agent
for such purpose at the Warrant Agent's office in New York, New York upon
surrender of this Warrant Certificate duly endorsed, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Warrant Agent
duly executed, with signatures guaranteed as specified in the attached Form of
Assignment, by the registered Holder hereof or his attorney duly authorized in
writing and by such other documentation required pursuant to the Warrant
Agreement and upon payment of any necessary transfer tax or other governmental
charge imposed upon such transfer. Upon any partial transfer, the Company will
sign and issue and the Warrant Agent will countersign and deliver to such Holder
a new Warrant Certificate or Certificates with respect to any portion not so
transferred. Each taker and Holder of this Warrant Certificate, by taking and
holding the same, consents and agrees that prior to the registration of transfer
as provided in the Warrant Agreement, the Company and the Warrant Agent may
treat the person in whose name the Warrants are registered as the absolute owner
hereof for any purpose and as the Person entitled to exercise the rights
represented hereby, any notice to the contrary notwithstanding. Accordingly, the
Company and/or the Warrant Agent shall not, except as ordered by a court of
competent jurisdiction as required by law, be bound to recognize any equitable
or other claim to or interest in the Warrants on the part of any person other
than such Registered Holder, whether or not it shall have express or other
notice thereof.

               This Warrant Certificate may be exchanged at the office of the
Warrant Agent maintained for such purpose in New York, New York, for Warrant
Certificates representing the same aggregate number of Warrants, each new
Warrant Certificate to represent such number of Warrants as the Holder hereof
shall designate at the time of such exchange.

               Each Holder hereby agrees that such Holder shall not sell,
transfer, make any short sale of, grant any option for the purchase of, or enter
into any hedging or similar transaction with the same economic effect as a sale
of any Warrants or Common Stock of the Company held by such Holder (other than
those included in the registration) for a period specified by the representative
of the underwriters of Common Stock of the Company not to exceed one hundred
eighty (180) days following the effective date of a registration statement of
the Company filed under the Securities Act; provided that:
<PAGE>

                                      A-5

          (i)    such agreement shall apply only to the Company's first firm
     commitment underwritten public offering of its Common Stock registered
     under the Securities Act, which is either the subject of a firm
     underwriting commitment or an on-line offering pursuant to the Dutch-
     auction process (the "Initial Offering");
                           ----------------

          (ii)   all officers and directors of the Company who hold capital
     stock or rights to acquire capital stock of the Company and greater than
     five percent (5%) stockholders of the Company enter into similar
     agreements; and

          (iii)  such agreement shall not apply to any shares of Common Stock
     (or other securities) purchased in the Initial Offering or purchased in the
     open market following the Initial Offering.

          Prior to the exercise of the Warrants represented hereby, the Holder
of this Warrant Certificate, as such, shall not be entitled to any rights of a
stockholder of the Company, including, without limitation, the right to vote or
to consent to any action of the stockholders, to receive any distributions, to
exercise any pre-emptive right or to receive any notice of meetings of
stockholders, and shall not be entitled to receive any notice of any proceedings
of the Company except as provided in the Warrant Agreement.

          This Warrant Certificate shall be void and all rights evidenced hereby
shall cease on February 9, 2010, unless sooner terminated by the liquidation,
dissolution or winding-up of the Company or as otherwise provided in the Warrant
Agreement upon the consolidation or merger of the Company with, or sale of the
Company to, another Person or unless such date is extended as provided in the
Warrant Agreement.

Dear Sirs:

          In connection with our proposed purchase of ___________ aggregate
number of Warrants, we confirm that:

          1.   We understand that any subsequent transfer of the Warrants, any
     interest therein or the Common Shares issuable upon exercise of any Warrant
     (the "Warrant Shares") is subject to certain restrictions and conditions
           --------------
     set forth in the Warrant Agreement dated as of February 9, 2000 relating to
     the Warrants (the "Warrant Agreement") and the Warrant Registration Rights
                        -----------------
     Agreement dated as of February 9, 2000 relating to the Warrants (the
     "Warrant Registration Rights Agreement") and the undersigned agrees to be
      -------------------------------------
     bound by, and not to resell, pledge or otherwise transfer the Warrants or
     Warrant Shares except in compliance with, such restrictions and conditions
     and the U.S. Securities Act of 1933, as amended (the "Securities Act").
                                                           --------------

          2.   We understand that the Warrants represented by this Warrant
     Certificate and, as of the date this Warrant Certificate was originally
     issued, the Warrant Shares have not been registered under the Securities
     Act, and accordingly may not be offered, sold, pledged or otherwise
     transferred within the United States or to, or for the account or benefit
     of, U.S. Persons except as set forth in the following sentence. We agree
     that we will not, within the time period referred to under Rule 144(k) of
     the Securities Act (taking into
<PAGE>

                                     B2-2

     account the provisions of Rule 144(d) under the Securities Act, if
     applicable) under the Securities Act as in effect on the date of the
     transfer of this Warrant, resell or otherwise transfer the Warrants
     represented by this Warrant Certificate except (a) to Loudcloud, Inc. or
     any subsidiary thereof, (b) following, the Rule 144A Availability Date, to
     a qualified institutional buyer in compliance with Rule 144A under the
     Securities Act, (c) pursuant to the exemption from registration provided by
     Rule 144 under the Securities Act (if available), (d) to an institutional
     accredited investor that, prior to such transfer, furnishes to you, to the
     Company and, in the case of the Warrant Shares, to the transfer agent and
     registrar therefor, a signed letter containing certain representations and
     agreements relating to the restrictions on transfer of the Warrants
     represented by this Warrant Certificate (the form of which letter can be
     obtained from the Warrant Agent) and an opinion of counsel acceptable to
     Loudcloud, Inc. and its counsel that such transfer is in compliance with
     the Securities Act or (e) pursuant to an effective registration statement
     under the Securities Act and, in each case, in accordance with applicable
     state securities laws.

          3.   We understand that, on any proposed resale of any Warrants, any
     interest therein or Warrant Shares, we will be required to furnish to you
     and the Company such certifications, legal opinions and other information
     as you and the Company may reasonably require to confirm that the proposed
     sale complies with the foregoing restrictions. We further understand that
     the Warrants purchased by us will bear a legend to the foregoing effect.

          4.   We are an institutional "accredited investor" (as defined in Rule
     501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and
     have such knowledge and experience in financial and business matters as to
     be capable of evaluating the merits and risks of our investment in the
     Warrants, and we and any accounts for which we are acting are each able to
     bear the economic risk of our or its investment for an indefinite period of
     time.

          5.   We are acquiring the Warrants purchased by us for our own account
     or for one or more accounts (each of which is an institutional "accredited
     investor") as to each of which we exercise sole investment discretion,
     without a view to distribution in violation of the Securities Act.

for the Warrant Shares are entitled to rely upon this letter and are irrevocably
authorized to produce this letter or a copy hereof to any interested party in

          2.   Registration Under the 1933 Act.
               -------------------------------

          (a)  To the extent not prohibited by any applicable law or applicable
interpretation of the staff of the SEC (the "Staff"), the Company shall use its
best efforts to cause to be filed no later than 21 months after the closing of
the Purchase Agreement, an Exchange Offer Registration Statement covering the
offer by the Company to the Holders to exchange all of the Registrable
Securities for Exchange Securities and to have such Registration Statement
remain effective until the closing of the Exchange Offer. The Company shall
commence the Exchange Offer promptly after the Exchange Offer Registration
Statement has been declared effective by the SEC and use its best efforts to
have the Exchange Offer consummated not later than 60 days after such effective
date. The Company shall commence the Exchange Offer by mailing the related
exchange offer Prospectus and accompanying documents to each Holder stating, in
addition to such other disclosures as are required by applicable law:

          (i)  that the Exchange Offer is being made pursuant to this Notes
     Registration Rights Agreement and that all Registrable Securities validly
     tendered will be accepted for exchange;
<PAGE>

                                       5

          (ii)  the dates of acceptance for exchange (which shall be a period of
     at least 20 days from the date such notice is mailed) (the "Exchange
     Dates");

          (iii) that any Registrable Security not tendered will remain
     outstanding and continue to accrue interest, but will not retain any rights
     under this Notes Registration Rights Agreement;

          (iv)  that Holders electing to have a Registrable Security exchanged
     pursuant to the Exchange Offer will be required to surrender such
     Registrable Security, together with the enclosed letters of transmittal, to
     the institution and at the address (located in the Borough of Manhattan,
     The City of New York) specified in the notice prior to the close of
     business on the last Exchange Date; and

          (v)   that Holders will be entitled to withdraw their election, not
     later than the close of business on the last Exchange Date, by sending to
     the institution and at the address (located in the Borough of Manhattan,
     The City of New York) specified in the notice a telegram, telex, facsimile
     transmission or letter setting forth the name of such Holder, the principal
     amount at maturity of Registrable Securities delivered for exchange and a
     statement that such Holder is withdrawing his election to have such
     Securities exchanged.

          As soon as practicable after the last Exchange Date, the Company
shall:

          (i)   accept for exchange Registrable Securities or portions thereof
     tendered and not validly withdrawn pursuant to the Exchange Offer; and

          (ii)  deliver, or cause to be delivered, to the Trustee for
     cancellation all Registrable Securities or portions thereof so accepted for
     exchange by the Company and issue, and cause the Trustee to promptly
     authenticate and mail to each Holder, an Exchange Security equal in
     principal amount at maturity to the principal amount at maturity of the
     Registrable Securities surrendered by such Holder.

The Company shall use its best efforts to complete the Exchange Offer as
provided above and shall comply with the applicable requirements of the 1933
Act, the 1934 Act and other applicable laws and regulations in connection with
the Exchange Offer. The Exchange Offer shall not be subject to any conditions,
other than that the Exchange Offer does not violate applicable law or any
applicable interpretation of the Staff of the SEC. The Company shall inform
MS&Co. of the names and addresses of the Holders to whom the Exchange Offer is
made, and MS&Co. or its affiliates shall have the right, subject to applicable
law, to contact such Holders and otherwise facilitate the tender of Registrable
Securities in the Exchange Offer.
<PAGE>

                                       6

          (b)  In the event that (i) the Company determines that the Exchange
Offer Registration provided for in Section 2(a) above is not available or may
not be consummated as soon as practicable after the last Exchange Date because
it would violate applicable law or the applicable interpretations of the Staff
of the SEC, (ii) the Exchange Offer is not for any other reason consummated
within 24 months after the closing of the Purchase Agreement, or (iii) the
Exchange Offer has been or will be completed and in the opinion of counsel for
MS&Co. or any of its assignees a Registration Statement must be filed and a
Prospectus must be delivered by MS&Co. or any of its assignees in connection
with any offering or sale of Registrable Securities, the Company shall use its
best efforts to cause to be filed as soon as practicable after such
determination, date or notice of such opinion of counsel is given to the
Company, as the case may be, a Shelf Registration Statement providing for the
sale by the Holders of all of the Registrable Securities and to have such Shelf
Registration Statement declared effective by the SEC. In the event the Company
is required to file a Shelf Registration Statement solely as a result of the
matters referred to in clause (iii) of the preceding sentence, the Company shall
use its best efforts to file and have declared effective by the SEC both an
Exchange Offer Registration Statement pursuant to Section 2(a) with respect to
all Registrable Securities and a Shelf Registration Statement (which may be a
combined Registration Statement with the Exchange Offer Registration Statement)
with respect to offers and sales of Registrable Securities held by MS&Co. or any
of its assignees after completion of the Exchange Offer. The Company agrees to
use its best efforts to keep the Shelf Registration Statement continuously
effective until the expiration of the period referred in Rule 144(k) or such
shorter period that will terminate when all of the Registrable Securities
covered by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement, and in the event a Registration Statement is required as
a result of the matters referred to in clause (iii) above, until all of the
Registrable Securities covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement. The Company further agrees to
supplement or amend the Shelf Registration Statement if required by the rules,
regulations or instructions applicable to the registration form used by the
Company for such Shelf Registration Statement or by the 1933 Act or by any other
rules and regulations thereunder for shelf registration or if reasonably
requested by a Holder with respect to information relating to such Holder, and
to use its best efforts to cause any such amendment to become effective and such
Shelf Registration Statement to become usable as soon as thereafter practicable.
The Company agrees to furnish to the Holders of Registrable Securities copies of
any such supplement or amendment promptly after its being used or filed with the
SEC.

          (c)  The Company shall pay all Registration Expenses in connection
with the registration pursuant to Section 2(a) or Section 2(b). Each Holder
shall pay all underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Registrable Securities
pursuant to the Shelf Registration Statement.

          (d)  An Exchange Offer Registration Statement pursuant to Section 2(a)
hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will
not be deemed to have
<PAGE>

                                       7

become effective unless it has been declared effective by the SEC; provided,
                                                                   --------
however, that, if, after it has been declared effective, the offering of
-------
Registrable Securities pursuant to a Shelf Registration Statement is interfered
with by any stop order, injunction or other order or requirement of the SEC or
any other governmental agency or court, such Registration Statement will be
deemed not to have become effective during the period of such interference until
the offering of Registrable Securities pursuant to such Registration Statement
may legally resume. As provided for in the Indenture, in the event the Exchange
Offer is not consummated and the Shelf Registration Statement is not declared
effective within 24 months after the closing of the Purchase Agreement, the
annual interest rate then in effect on the Securities (and the Exchange
Securities) will increase by 0.5% until the Exchange Offer is consummated, the
Shelf Registration Statement is declared effective or the Securities become
freely tradeable under the Act.

          (e)  Without limiting the remedies available to MS&Co. and the
Holders, the Company acknowledges that any failure by the Company to comply with
its obligations under Section 2(a) and Section 2(b) hereof may result in
material irreparable injury to MS&Co. or the Holders for which there is no
adequate remedy at law, that it will not be possible to measure damages for such
injuries precisely and that, in the event of any such failure, MS&Co. or any
Holder may obtain such relief as may be required to specifically enforce the
Company's obligations under Section 2(a) and Section 2(b) hereof.

          3.   Registration Procedures.
               -----------------------

          In connection with the obligations of the Company with respect to the
Registration Statements pursuant to Section 2(a) and Section 2(b) hereof, the
Company shall as expeditiously as possible:

          (a)  prepare and file with the SEC a Registration Statement on the
     appropriate form under the 1933 Act, which form (x) shall be selected by
     the Company and (y) shall, in the case of a Shelf Registration, be
     available for the sale of the Registrable Securities by the selling Holders
     thereof and (z) shall comply as to form in all material respects with the
     requirements of the applicable form and include all financial statements
     required by the SEC to be filed therewith, and use its best efforts to
     cause such Registration Statement to become effective and remain effective
     in accordance with Section 2 hereof;

          (b)  prepare and file with the SEC such amendments and post-effective
     amendments to each Registration Statement as may be necessary to keep such
     Registration Statement effective for the applicable period and cause each
     Prospectus to be supplemented by any required prospectus supplement and, as
     so supplemented, to be filed pursuant to Rule 424 under the 1933 Act; to
     keep each Prospectus current during the period described under Section 4(3)
     and Rule 174 under the 1933 Act that is applicable to
<PAGE>

                                       8

     transactions by brokers or dealers with respect to the Registrable
     Securities or Exchange Securities;

          (c)  in the case of a Shelf Registration, furnish to each Holder of
     Registrable Securities, to counsel for MS&Co., to counsel for the Holders
     and to each Underwriter of an Underwritten Offering of Registrable
     Securities, if any, without charge, as many copies of each Prospectus,
     including each preliminary Prospectus, and any amendment or supplement
     thereto and such other documents as such Holder or Underwriter may
     reasonably request, in order to facilitate the public sale or other
     disposition of the Registrable Securities; and the Company consents to the
     use of such Prospectus and any amendment or supplement thereto in
     accordance with applicable law by each of the selling Holders of
     Registrable Securities and any such Underwriters in connection with the
     offering and sale of the Registrable Securities covered by and in the
     manner described in such Prospectus or any amendment or supplement thereto
     in accordance with applicable law;

          (d)  use its best efforts to register or qualify the Registrable
     Securities under all applicable state securities or "blue sky" laws of such
     jurisdictions as any Holder of Registrable Securities covered by a
     Registration Statement shall reasonably request in writing by the time the
     applicable Registration Statement is declared effective by the SEC, to
     cooperate with such Holders in connection with any filings required to be
     made with the National Association of Securities Dealers, Inc. and do any
     and all other acts and things which may be reasonably necessary or
     advisable to enable such Holder to consummate the disposition in each such
     jurisdiction of such Registrable Securities owned by such Holder; provided,
                                                                       --------
     however, that the Company shall not be required to (i) qualify as a foreign
     -------
     corporation or as a dealer in securities in any jurisdiction where it would
     not otherwise be required to qualify but for this Section 3(d), (ii) file
     any general consent to service of process or (iii) subject itself to
     taxation in any such jurisdiction if it is not so subject;

          (e)  in the case of a Shelf Registration, notify each Holder of
     Registrable Securities, counsel for the Holders and counsel for MS&Co.
     promptly and, if requested by any such Holder or counsel, confirm such
     advice in writing (i) when a Registration Statement has become effective
     and when any post-effective amendment thereto has been filed and becomes
     effective, (ii) of any request by the SEC or any state securities authority
     for amendments and supplements to a Registration Statement and Prospectus
     or for additional information after the Registration Statement has become
     effective, (iii) of the issuance by the SEC or any state securities
     authority of any stop order suspending the effectiveness of a Registration
     Statement or the initiation of any proceedings for that purpose, (iv) if,
     between the effective date of a Registration Statement and the closing of
     any sale of Registrable Securities covered thereby, the representations and
     warranties of the Company contained in any underwriting agreement,
     securities sales agreement or
<PAGE>

                                       9

     other similar agreement, if any, relating to the offering cease to be true
     and correct in all material respects or if the Company receives any
     notification with respect to the suspension of the qualification of the
     Registrable Securities for sale in any jurisdiction or the initiation of
     any proceeding for such purpose, (v) of the happening of any event during
     the period a Shelf Registration Statement is effective which makes any
     statement made in such Registration Statement or the related Prospectus
     untrue in any material respect or which requires the making of any changes
     in such Registration Statement or Prospectus in order to make the
     statements therein not misleading and (vi) of any determination by the
     Company that a post-effective amendment to a Registration Statement would
     be appropriate;

          (f)  make every reasonable effort to obtain the withdrawal of any
     order suspending the effectiveness of a Registration Statement at the
     earliest possible moment and provide immediate notice to each Holder of the
     withdrawal of any such order;

          (g)  in the case of a Shelf Registration, furnish to each Holder of
     Registrable Securities, without charge, at least one conformed copy of each
     Registration Statement and any post-effective amendment thereto (without
     documents incorporated therein by reference or exhibits thereto, unless
     requested);

          (h)  in the case of a Shelf Registration, cooperate with the selling
     Holders of Registrable Securities to facilitate the timely preparation and
     delivery of certificates representing Registrable Securities to be sold and
     not bearing any restrictive legends and enable such Registrable Securities
     to be in such denominations (consistent with the provisions of the
     Indenture) and registered in such names as the selling Holders may
     reasonably request at least one business day prior to the closing of any
     sale of Registrable Securities;

          (i)  in the case of a Shelf Registration, upon the occurrence of any
     event contemplated by Section 3(e)(v) hereof, use its best efforts to
     prepare and file with the SEC a supplement or post-effective amendment to a
     Registration Statement or the related Prospectus or any document
     incorporated therein by reference or file any other required document so
     that, as thereafter delivered to the purchasers of the Registrable
     Securities, such Prospectus will not contain any untrue statement of a
     material fact or omit to state a material fact necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading. The Company agrees to notify the Holders to suspend
     use of the Prospectus as promptly as practicable after the occurrence of
     such an event, and the Holders hereby agree to suspend use of the
     Prospectus until the Company has amended or supplemented the Prospectus to
     correct such misstatement or omission;

          (j)  a reasonable time prior to the filing of any Registration
     Statement, any Prospectus, any amendment to a Registration Statement or
     amendment or supplement to a
<PAGE>

                                       10

     Prospectus or any document which is to be incorporated by reference into a
     Registration Statement or a Prospectus after initial filing of a
     Registration Statement, provide copies of such document to MS&Co. and its
     counsel (and, in the case of a Shelf Registration Statement, the Holders
     and their counsel) and make such of the representatives of the Company as
     shall be reasonably requested by MS&Co. or its counsel (and, in the case of
     a Shelf Registration Statement, the Holders or their counsel) available for
     discussion of such document, and shall not at any time file or make any
     amendment to the Registration Statement, any Prospectus or any amendment of
     or supplement to a Registration Statement or a Prospectus or any document
     which is to be incorporated by reference into a Registration Statement or a
     Prospectus, of which MS&Co. and its counsel (and, in the case of a Shelf
     Registration Statement, the Holders and their counsel) shall not have
     previously been advised and furnished a copy or to which MS&Co. or its
     counsel (and, in the case of a Shelf Registration Statement, the Holders or
     their counsel) shall object (unless in the opinion of counsel to the
     Company, the Company is required by applicable law or regulation to file or
     amend the same);

          (k)  obtain a CUSIP number for all Exchange Securities or Registrable
     Securities, as the case may be, not later than the effective date of a
     Registration Statement;

          (l)  cause the Indenture to be qualified under the Trust Indenture Act
     of 1939, as amended (the "TIA"), in connection with the registration of the
     Exchange Securities or Registrable Securities, as the case may be,
     cooperate with the Trustee and the Holders to effect such changes to the
     Indenture as may be required for the Indenture to be so qualified in
     accordance with the terms of the TIA and execute, and use its best efforts
     to cause the Trustee to execute, all documents as may be required to effect
     such changes and all other forms and documents required to be filed with
     the SEC to enable the Indenture to be so qualified in a timely manner;

          (m)  in the case of a Shelf Registration, upon the execution of
     customary confidentiality agreements reasonably satisfactory to the
     Company, make available for inspection by a representative of the Holders
     of the Registrable Securities, any Underwriter participating in any
     disposition pursuant to such Shelf Registration Statement, and attorneys
     and accountants designated by the Holders, at reasonable times and in a
     reasonable manner, all financial and other records, pertinent documents and
     properties of the Company, and cause the respective officers, directors and
     employees of the Company to supply all information reasonably requested by
     any such representative, Underwriter, attorney or accountant in connection
     with a Shelf Registration Statement;

          (n)  in the case of a Shelf Registration, use its best efforts to
     cause all Registrable Securities to be listed on any securities exchange or
     any automated quotation system on which similar securities issued by the
     Company are then listed if requested by
<PAGE>

                                       11

     the Majority Holders, to the extent such Registrable Securities satisfy
     applicable listing requirements;

          (o)  if requested by MS&Co., use its best efforts to cause the
     Exchange Securities or Registrable Securities, as the case may be, to be
     rated by two nationally recognized statistical rating organizations (as
     such term is defined in Rule 436(g)(2) under the 1933 Act);

          (p)  if reasonably requested by any Holder of Registrable Securities
     covered by a Registration Statement, (i) promptly incorporate in a
     Prospectus supplement or post-effective amendment such information with
     respect to such Holder as such Holder reasonably requests to be included
     therein and (ii) make all required filings of such Prospectus supplement or
     such post-effective amendment promptly after the Company has received
     notification of the matters to be incorporated in such filing; and

          (q)  in the case of a Shelf Registration, enter into such customary
     agreements and take all such other actions in connection therewith
     (including those requested by the Holders of a majority of the Registrable
     Securities being sold) in order to expedite or facilitate the disposition
     of such Registrable Securities including, but not limited to, an
     Underwritten Offering and in such connection, (i) to the extent possible,
     make such representations and warranties to the Holders and any
     Underwriters of such Registrable Securities with respect to the business of
     the Company and its subsidiaries, the Registration Statement, Prospectus
     and documents incorporated by reference or deemed incorporated by
     reference, if any, in each case, in form, substance and scope as are
     customarily made by issuers to underwriters in underwritten offerings and
     confirm the same if and when requested, (ii) obtain opinions of counsel to
     the Company (which counsel and opinions, in form, scope and substance,
     shall be reasonably satisfactory to the Holders and such Underwriters and
     their respective counsel) addressed to each selling Holder and Underwriter
     of Registrable Securities, covering the matters customarily covered in
     opinions requested in underwritten offerings, (iii) obtain "cold comfort"
     letters from the independent certified public accountants of the Company
     (and, if necessary, any other certified public accountant of any subsidiary
     of the Company, or of any business acquired by the Company for which
     financial statements and financial data are or are required to be included
     in the Registration Statement) addressed to each selling Holder and
     Underwriter of Registrable Securities, such letters to be in customary form
     and covering matters of the type customarily covered in "cold comfort"
     letters in connection with underwritten offerings, and (iv) deliver such
     documents and certificates as may be reasonably requested by the Holders of
     a majority in principal amount at maturity of the Registrable Securities
     being sold or the Underwriters, and which are customarily delivered in
     underwritten offerings, to evidence the continued validity of the
     representations and warranties of the Company made pursuant to clause (i)
     above and to
<PAGE>

                                       12

     evidence compliance with any customary conditions contained in an
     underwriting agreement.

          In the case of a Shelf Registration Statement, the Company may require
each Holder of Registrable Securities to furnish to the Company such information
regarding the Holder and the proposed distribution by such Holder of such
Registrable Securities as the Company may from time to time reasonably request
in writing and the Company may exclude from such registration the Securities of
any Holder that unreasonably fails to furnish such information within a
reasonable time after receiving such request until such Holder provides such
information.

          In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company of the happening of any event
of the kind described in Section 3(e)(v) hereof, such Holder will forthwith
discontinue disposition of Registrable Securities pursuant to a Registration
Statement until such Holder's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 3(i) hereof, and, if so directed by
the Company, such Holder will deliver to the Company (at its expense) all copies
in its possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Registrable Securities current at
the time of receipt of such notice. If the Company shall give any such notice to
suspend the disposition of Registrable Securities pursuant to a Registration
Statement, the Company shall extend the period during which the Registration
Statement shall be maintained effective pursuant to this Agreement by the number
of days during the period from and including the date of the giving of such
notice to and including the date when the Holders shall have received copies of
the supplemented or amended Prospectus necessary to resume such dispositions.
The Company may give any such notice only twice during any 365-day period and
any such suspensions may not exceed 60 days for each suspension and there may
not be more than two suspensions in effect during any 365-day period.

          The Holders of Registrable Securities covered by a Shelf Registration
Statement who desire to do so may sell such Registrable Securities in an
Underwritten Offering. In any such Underwritten Offering, the investment banker
or investment bankers and manager or managers (the "Underwriters") that will
administer the offering will be selected by the Majority Holders of the
Registrable Securities included in such offering.

          4.   Participation of Broker-Dealers in Exchange Offer.
               --------------------------------------------------

          (a)  The Company understands that the Staff of the SEC has taken the
position that any broker-dealer that receives Exchange Securities for its own
account in the Exchange Offer in exchange for Securities that were acquired by
such broker-dealer as a result of market-making or other trading activities (a
"Participating Broker-Dealer"), may be deemed to be an "underwriter" within the
meaning of the 1933 Act and must deliver a prospectus meeting the requirements
of the 1933 Act in connection with any resale of such Exchange Securities.
<PAGE>

                                       13

          The Company understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Securities, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Securities owned by them, such Prospectus may be delivered by Participating
Broker-Dealers to satisfy their prospectus delivery obligation under the 1933
Act in connection with resales of Exchange Securities for their own accounts, so
long as the Prospectus otherwise meets the requirements of the 1933 Act.

          (b)  In light of the above, notwithstanding the other provisions of
this Agreement, the Company agrees that the provisions of this Agreement as they
relate to a Shelf Registration shall also apply to an Exchange Offer
Registration to the extent, and with such reasonable modifications thereto as
may be, reasonably requested by MS&Co. or by one or more Participating Broker-
Dealers, in each case as provided in clause (ii) below, in order to expedite or
facilitate the disposition of any Exchange Securities by Participating Broker-
Dealers consistent with the positions of the Staff recited in Section 4(a)
above; provided that:
       -------- ----

          (i)  the Company shall not be required to amend or supplement the
     Prospectus contained in the Exchange Offer Registration Statement, as would
     otherwise be contemplated by Section 3(i), for a period exceeding 180 days
     after the last Exchange Date (as such period may be extended pursuant to
     the penultimate paragraph of Section 3 of this Agreement) and Participating
     Broker-Dealers shall not be authorized by the Company to deliver and shall
     not deliver such Prospectus after such period in connection with the
     resales contemplated by this Section 4; and

          (ii) the application of the Shelf Registration procedures set forth in
     Section 3 of this Agreement to an Exchange Offer Registration, to the
     extent not required by the positions of the Staff of the SEC or the 1933
     Act and the rules and regulations thereunder, will be in conformity with
     the reasonable request to the Company by MS&Co. or with the reasonable
     request in writing to the Company by one or more broker-dealers who certify
     to the Company in writing that they anticipate that they will be
     Participating Broker-Dealers; and provided further that, in connection with
                                       -------- -------
     such application of the Shelf Registration procedures set forth in Section
     3 to an Exchange Offer Registration, the Company shall be obligated (x) to
     deal only with one entity representing the Participating Broker-Dealers,
     which shall be MS&Co. unless it elects not to act as such representative,
     (y) to pay the fees and expenses of only one counsel representing the
     Participating Broker-Dealers, which shall be counsel to MS&Co. unless such
     counsel elects not to so act and (z) to cause to be delivered only one, if
     any, "cold comfort" letter with respect to the Prospectus in the form
     existing on the last Exchange Date and with respect to each subsequent
     amendment or supplement, if any, effected during the period specified in
     clause (i) above.

                                       14

          (c)  MS&Co. and its affiliates shall have no liability to the Company
or any Holder with respect to any request that it may make pursuant to Section
4(b) above.

          5.   Indemnification and Contribution.
               --------------------------------

          (a)  The Company agrees to indemnify and hold harmless MS&Co. and its
affiliates, each Holder and each person, if any, who controls MS&Co. or any
affiliates or any Holder within the meaning of either Section 15 of the 1933 Act
or Section 20 of the 1934 Act, or is under common control with, or is controlled
by, MS&Co. and its affiliates or any Holder, from and against all losses,
claims, damages and liabilities (including, without limitation, any legal or
other expenses reasonably incurred by MS&Co. and its affiliates, any Holder or
any such controlling or affiliated person in connection with defending or
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement (or any amendment thereto) pursuant to which Exchange Securities or
Registrable Securities were registered under the 1933 Act, including all
documents incorporated therein by reference, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, or caused by any
untrue statement or alleged untrue statement of a material fact contained in any
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact necessary to make the statements
therein in light of the circumstances under which they were made not misleading,
except insofar as such losses, claims, damages or liabilities are caused by any
such untrue statement or omission or alleged untrue statement or omission based
upon information relating to MS&Co. and its affiliates or any Holder furnished
to the Company in writing by MS&Co. and its affiliates or any selling Holder
expressly for use therein; provided that the foregoing indemnity with respect to
any preliminary Prospectus shall not inure to the benefit of any Holder from
whom the person asserting any such losses, claims, damages or liabilities
purchased Securities, or any person controlling such Holder, if a copy of the
final Prospectus (as then amended or supplemented if Company shall have
furnished any amendments or supplements thereto) was not sent or given by or on
behalf of such Holder to such person, if required by law so to have been
delivered, at or prior to the written confirmation of the sale of the Securities
to such person, and if the final Prospectus (as so amended or supplemented)
would have cured the defect giving rise to such loss, claim or liability. In
connection with any Underwritten Offering permitted by Section 3, the Company
will also indemnify the Underwriters, if any, selling brokers, dealers and
similar securities industry professionals participating in the distribution,
their officers and directors and each Person who controls such Persons (within
the meaning of the 1933 Act and the 1934 Act) to the same extent as provided
above with respect to the indemnification of the Holders, if requested in
connection with any Registration Statement.

          (b)  Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, MS&Co. and its affiliates and the other selling
Holders, and each of their
<PAGE>

                                       15

respective directors, officers who sign the Registration Statement and each
Person, if any, who controls the Company, MS&Co. and its affiliates and any
other selling Holder within the meaning of either Section 15 of the 1933 Act or
Section 20 of the 1934 Act to the same extent as the foregoing indemnity from
the Company to MS&Co. and its affiliates and the Holders, but only with
reference to information relating to such Holder furnished to the Company in
writing by such Holder expressly for use in any Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto).

          (c)  In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to either paragraph (a) or paragraph (b) above, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for (a) the fees and expenses of more than one separate
firm (in addition to any local counsel) for MS&Co. and its affiliates and all
persons, if any, who control MS&Co. and its affiliates within the meaning of
either Section 15 of the 1933 Act or Section 20 of the 1934 Act, (b) the fees
and expenses of more than one separate firm (in addition to any local counsel)
for the Company, its directors, its officers who sign the Registration Statement
and each person, if any, who controls the Company within the meaning of either
such Section and (c) the fees and expenses of more than one separate firm (in
addition to any local counsel) for all Holders and all persons, if any, who
control any Holders within the meaning of either such Section, and that all such
fees and expenses shall be reimbursed as they are incurred. In such case
involving MS&Co. and its affiliates and persons who control MS&Co. and its
affiliates, such firm shall be designated in writing by MS&Co. In such case
involving the Holders and such persons who control any Holders, such firm shall
be designated in writing by the Majority Holders. In all other cases, such firm
shall be designated by the Company. The indemnifying party shall not be liable
for any settlement of any proceeding effected without its written consent but,
if settled with such consent or if there be a final judgment for the plaintiff,
the indemnifying party agrees to indemnify the indemnified party from and
against any loss or liability by reason of such settlement or judgment.
Notwithstanding the foregoing sentence, if at any time an indemnified party
shall have requested an indemnifying party to reimburse the indemnified party
for fees and expenses of counsel as contemplated by the second and third
sentences of this paragraph, the
<PAGE>

                                       16

indemnifying party agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 60 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party for such fees and expenses of counsel in accordance with such
request prior to the date of such settlement. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which such
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

          (d)  If the indemnification provided for in paragraph (a) or paragraph
(b) of this Section 5 is unavailable to an indemnified party or insufficient in
respect of any losses, claims, damages or liabilities, then each indemnifying
party under such paragraph, in lieu of indemnifying such indemnified party
thereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party or parties on the one hand and of the indemnified party or parties on the
other hand in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the Holders shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by the Holders
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Holders'
respective obligations to contribute pursuant to this Section 5(d) are several
in proportion to the respective amount of Registrable Securities of such Holder
that were registered pursuant to a Registration Statement.

          (e)  The Company and each Holder agree that it would not be just or
equitable if contribution pursuant to this Section 5 were determined by pro rata
                                                                        --- ----
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in paragraph (d) above. The amount paid
or payable by an indemnified party as a result of the losses, claims, damages
and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 5, no Holder shall be required to indemnify or contribute any amount in
excess of the amount by which the total price at which Registrable Securities
were sold by such Holder exceeds the amount of any damages that such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 5
<PAGE>

                                       17

are not exclusive and shall not limit any rights or remedies which may otherwise
be available to any indemnified party at law or in equity.

          The indemnity and contribution provisions contained in this Section 5
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
MS&Co., any Holder or any person controlling MS&Co. or any Holder, or by or on
behalf of the Company, its officers or directors or any person controlling the
Company, (iii) acceptance of any of the Exchange Securities and (iv) any sale of
Registrable Securities pursuant to a Shelf Registration Statement.

          6.   Miscellaneous.
               -------------

          (a)  No Inconsistent Agreements. The Company has not entered into, and
               --------------------------
on or after the date of this Agreement will not enter into, any agreement which
is inconsistent with the rights granted to the Holders of Registrable Securities
in this Agreement or otherwise conflicts with the provisions hereof. The rights
granted to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's other
issued and outstanding securities under any such agreements.

          (b)  Amendments and Waivers. The provisions of this Agreement,
               ----------------------
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of MS&Co.
and the Holders of at least a majority in aggregate principal amount at maturity
of the outstanding Registrable Securities affected by such amendment,
modification, supplement, waiver or consent; provided, however, that no
                                             --------  -------
amendment, modification, supplement, waiver or consents to any departure from
the provisions of Section 5 hereof shall be effective as against any Holder of
Registrable Securities unless consented to in writing by such Holder.

          (c)  Notices. All notices and other communications provided for or
               -------
permitted hereunder shall be made in writing by hand-delivery, registered first-
class mail, telex, telecopier, or any courier guaranteeing overnight delivery
(i) if to a Holder, at the most current address given by such Holder to the
Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address initially is, with respect to MS&Co., the address
set forth in the Purchase Agreement; (ii) if to the Trustee, initially at the
Trustee's address set forth in the Indenture and thereafter at such other
address, notice of which is given in accordance with the provisions of this
Section 6(c); and (iii) if to the Company, initially at the Company's address
set forth in the Purchase Agreement and thereafter at such other address, notice
of which is given in accordance with the provisions of this Section 6(c).

          All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; five business
days after being deposited in the
<PAGE>

                                       18

mail, postage prepaid, if mailed; when answered back, if telexed; when receipt
is acknowledged, if telecopied; and on the next business day if timely delivered
to an air courier guaranteeing overnight delivery.

          Copies of all such notices, demands, or other communications shall be
concurrently delivered by the person giving the same to the Trustee, at the
address specified in the Indenture.

          (d)  Successors and Assigns. This Agreement shall inure to the benefit
               ----------------------
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
                                --------
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement. If any transferee of any
Holder shall acquire Registrable Securities, in any manner, whether by operation
of law or otherwise, such Registrable Securities shall be held subject to all of
the terms of this Agreement, and by taking and holding such Registrable
Securities such person shall be conclusively deemed to have agreed to be bound
by and to perform all of the terms and provisions of this Agreement and such
person shall be entitled to receive the benefits hereof. MS&Co. shall have no
liability or obligation to the Company with respect to any failure by a Holder
to comply with, or any breach by any Holder of, any of the obligations of such
Holder under this Agreement.

          (e)  Third Party Beneficiary. The Holders shall be third party
               -----------------------
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Trustee, on the other hand, and any Holder shall have the right to
enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

          (f)  Counterparts. This Agreement may be executed in any number of
               ------------
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

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

          (h)  Governing Law. This Agreement shall be governed by and construed
               -------------
in accordance with the laws of the State of New York.

          (i)  Severability. In the event that any one or more of the provisions
               -------------
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.
