               (other than under the circumstances described in Section 3 or 4),
               the holder thereof shall have given written notice to the Company

               shall describe the manner of the proposed transfer and, if
               requested by the Company, shall be accompanied by an opinion of
               counsel, which opinion is in form and substance satisfactory to
               the Company to the effect that the proposed transfer may be
               effected without registration under the Securities Act, whereupon
               the holder of such stock shall be entitled to transfer such stock
               in accordance with the terms of its notice. Each certificate for
               Registrable Stock transferred as provided above shall bear the
               legend required pursuant to Section 7.09 of the Merger Agreement
               or 6.09 of the Stock Purchase Agreement, as applicable, except
               that such certificate shall not bear such legend if (i) such
               transfer is in accordance with the provisions of Rule 144 (or any
               other rule permitting public sale without registration under the
               Securities Act) or (ii) the opinion of counsel referred to above
               is to the further effect that the transferee and any subsequent
               transferee (other than an Affiliate of the Company) would be
               entitled to transfer such securities in a public sale without
               registration under the Securities Act.

                    (b) Notwithstanding the provisions of Section 2(a) of this
               Agreement, the Purchasers shall not transfer, sell, pledge, gift
               or bequeath any Escrow Shares without the written consent of the
               Company, which consent shall not be unreasonably withheld.

                  3. Demand for Registration.

                    (a) On and after the date that is six (6) months from the
               date of this Agreement, the Holders of at least 331/3% of the
               Registrable Stock (the "Initiating Holders") may demand in a
               written notice (the "Registration Demand") that the Company file
               a registration statement under the Securities Act (or a similar
               document pursuant to any other statute then in effect
               corresponding to the Securities Act) covering the registration of
               any or all Registrable Stock held by such Initiating Holders in
               the manner specified in such notice, provided that the aggregate
               amount of Registrable Stock to be included in such registration
               shall be equal to at least the Minimum Demand Amount, but not
               more than 50% (the "Maximum Demand Amount"), of the total
               Registrable Stock held by such Holder. Following receipt of any
               notice under this Section 3 the Company shall (x) within twenty
               (20) days notify all other Holders of such request in writing and
               (y) use its reasonable efforts to cause to be registered under
               the Securities Act, subject to the proviso of the immediately
               preceding sentence, all Registrable Stock that the Initiating
               Holders and such other Holders have demanded, within forty (40)
               days after the Company has received the Registration Demand, be
               registered in accordance with the manner of disposition specified
               in such notice by the Initiating Holders.

                    (b) Notwithstanding any provision of this Agreement to the
               contrary:






                                        5

                    (i)  the Company shall not be required to effect a
                         registration pursuant to this Section 3 during the
                         period starting with the date of filing by the Company
                         of, and ending on a date one hundred twenty (120) days
                         following the effective date of, a registration
                         statement pertaining to a public offering of securities
                         for the account of the Company or on behalf of the
                         selling stockholders under any other registration
                         rights agreement which the Holders have been entitled
                         to join pursuant to Section 4; provided that the
                         Company shall actively employ in good faith all
                         reasonable efforts to cause such registration
                         statement to become effective as soon as possible; and

                    (ii) if the Company shall determine in good faith that such
                         registration would interfere with any material
                         transaction then being pursued by the Company, the
                         Company's obligation to use its reasonable efforts to
                         file a registration statement shall be deferred for a
                         period not to exceed ninety (90) days.

                    (c) The Company shall not be obligated to effect and pay for
               more than one (1) registration pursuant to this Section 3;
               provided, that a registration demanded pursuant to this Section 3
               shall not be deemed to have been effected for purposes of this
               Section 3(d) unless (i) it has been declared effective by the
               SEC, (ii) it has remained effective for the period set forth in
               Section 5(a) and (iii) the offering of Registrable Stock pursuant
               to such registration is not subject to any stop order, injunction
               or other order or requirement of the SEC (other than any such
               stop order, injunction, or other requirement of the SEC prompted
               by any act or omission of Holders of Registrable Stock).

                  4. Participatory Registration. Subject to Sections 7 and 9, if
at any time the Company determines that it shall file a registration statement
under the Securities Act (other than a registration statement on a Form S-4 or
S-8 or filed in connection with an exchange offer or an offering of securities
solely to the Company's existing stockholders) on any form that would also
permit the registration of the Registrable Stock and such filing is to be on its
behalf and/or on behalf of selling holders of its securities for the general
registration of its Common Stock to be sold for cash, the Company shall each
such time promptly give each Holder written notice of such determination setting
forth the date on which the Company proposes to file such registration
statement, which date shall be no earlier than fifteen (15) days from the date
of such notice, and advising each Holder of its right to have Registrable Stock
included in such registration. Upon the written request of any Holder received
by the Company no later than ten (10) days after the date of receipt of the
Company's notice, the Company shall use its reasonable efforts to cause to be
registered under the Securities Act all





                                        6

of the Registrable Stock that each such Holder has so requested to be
registered; provided that the amount of Registrable Stock included in such
registration shall be equal to at least the Minimum Amount but not more than the
Maximum Amount. If, in the opinion of the managing underwriter (or, in the case
of a non-underwritten offering, in the opinion of the Company), the total amount
of such securities to be so registered, including such Registrable Stock, will
exceed the maximum amount of the Company's securities which can be marketed (a)
at a price reasonably related to the then current market value of such
securities, or (b) without otherwise materially and adversely affecting the
entire offering, then the Company shall be entitled to reduce the number of
shares of Registrable Stock to be registered in such offering. Any reduction
made pursuant to the immediately preceding sentence shall be made pro rata among
any such Holders and any other security holders of the Company registering
securities in such registration.

                  5. Obligations of the Company. Whenever required under Section
3 to use its reasonable efforts to effect the registration of any Registrable
Stock, the Company shall, as expeditiously as possible:

                    (a) prepare and file with the SEC a registration statement
               signed, pursuant to Section 6(a) of the Securities Act, by the
               officers and directors of the Company with respect to such
               Registrable Stock and use its reasonable efforts to cause such
               registration statement to become and remain effective for the
               period of the distribution contemplated thereby determined as
               hereinafter provided;

                    (b) prepare and file with the SEC such amendments and
               supplements to such registration statement signed, pursuant to
               Section 6(a) of the Securities Act, by the officers and directors
               of the Company and the prospectus used in connection therewith as
               may be necessary to comply with the provisions of the Securities
               Act with respect to the disposition of all Registrable Stock
               covered by such registration statement;

                    (c) furnish to the Holders such numbers of copies of the
               registration statement and the prospectus included therein
               (including each preliminary prospectus and any amendments or
               supplements thereto in conformity with the requirements of the
               Securities Act) and such other documents and information as they
               may reasonably request;

                    (d) use its reasonable efforts to register or qualify the
               Registrable Stock covered by such registration statement under
               such other securities or blue sky laws of such jurisdiction
               within the United States and Puerto Rico as shall be reasonably
               appropriate for the distribution of the Registrable Stock covered
               by the registration statement; provided, however, that the
               Company shall not be required in connection therewith or as a
               condition thereto to qualify to do business in or to file a
               general





                                        7

               consent to service of process in any jurisdiction wherein it
               would not but for the requirements of this paragraph (d) be
               obligated to do so; and provided, further, that the Company shall
               not be required to qualify such Registrable Stock in any
               jurisdiction in which the securities regulatory authority
               requires that any Holder submit any shares of its Registrable
               Stock to the terms, provisions and restrictions of any escrow,
               lockup or similar agreement(s) for consent to sell Registrable
               Stock in such jurisdiction unless such Holder agrees to do so;

                    (e) promptly notify each Holder for whom such Registrable
               Stock is covered by such registration statement, at any time when
               a prospectus relating thereto is required to be delivered under
               the Securities Act, of the happening of any event as a result of
               which the prospectus included in such registration statement, as
               then in effect, includes an untrue statement of a material fact
               or omits to state any material fact required to be stated therein
               or necessary to make the statements therein not misleading in
               light of the circumstances under which they were made, and at the
               request of any such Holder promptly prepare and furnish to such
               Holder a reasonable number of copies of a supplement to or an
               amendment of such prospectus as may be necessary so that, as
               thereafter delivered to the purchasers of such securities, such
               prospectus shall not include an untrue statement of a material
               fact or omit to state a material fact required to be stated
               therein or necessary to make the statements therein not
               misleading in light of the circumstances under which they were
               made;

                    (f) furnish, at the request of any Holder demanding
               registration of Registrable Stock pursuant to Section 3, if the
               method of distribution is by means of an underwriting, on the
               date that the shares of Registrable Stock are delivered to the
               underwriters for sale pursuant to such registration, or if such
               Registrable Stock is not being sold through underwriters, on the
               date that the registration statement with respect to such shares
               of Registrable Stock becomes effective, (i) a signed opinion,
               dated such date, of the independent legal counsel representing
               the Company for the purpose of such registration, addressed to
               the underwriters, if any, and if such Registrable Stock is not
               being sold through underwriters, then to the Holders making such
               request, as to such matters as such underwriters or the Holders
               holding a majority of the Registrable Stock included in such
               registration, as the case may be, may reasonably request and as
               would be customary in such a transaction; and (ii) letters dated
               such date and the date the offering is priced from the
               independent certified public accountants of the Company,
               addressed to the underwriters, if any, and if such Registrable
               Stock is not being sold through underwriters, then to the Holders
               making such request and, if such accountants refuse to deliver
               such letters to such Holders, then to the Company (A) stating
               that they are independent certified public accountants within the
               meaning of the Securities Act and that, in the opinion of such
               accountants, the financial statements and other financial data of
               the Company included in the registration statement or the





                                        8

               prospectus, or any amendment or supplement thereto, comply as to
               form in all material respects with the applicable accounting
               requirements of the Securities Act and (B) covering such other
               financial matters (including information as to the period ending
               not more than five (5) business days prior to the date of such
               letters) with respect to the registration in respect of which
               such letter is being given as such underwriters or the Holders
               holding a majority of the Registrable Stock included in such
               registration, as the case may be, may reasonably request and as
               would be customary in such a transaction;

                    (g) enter into customary agreements (including if the method
               of distribution is by means of an underwriting, an underwriting
               agreement in customary form) and take such other actions as are
               reasonably required in order to expedite or facilitate the
               disposition of the Registrable Stock to be so included in the
               registration statement;

                    (h) otherwise use its reasonable efforts to comply with all
               applicable rules and regulations of the SEC, and make available
               to its security holders, as soon as reasonably practicable, but
               not later than eighteen (18) months after the effective date of
               the registration statement, an earnings statement covering the
               period of at least twelve (12) months beginning with the first
               full month after the effective date of such registration
               statement, which earnings statements shall satisfy the provisions
               of Section 11(a) of the Securities Act;

                    (i) use its reasonable efforts to list the Registrable Stock
               covered by such registration statement with any securities
               exchange on which the Common Stock is then listed; and

                    (j) shall use its reasonable efforts to cause such
               Registration Statement (i) to become effective as soon as
               possible after the filing thereof and (ii) to remain effective,
               with a prospectus at all times meeting the requirements of the
               Securities Act for so long as a prospectus may be required to be
               delivered pursuant to the Securities Act.

For purposes of Sections 5(a) and 5(b), the period of distribution of
Registrable Stock in a firm commitment underwritten public offering shall be
deemed to extend until each underwriter has completed the distribution of all
securities purchased by it, and the period of distribution of Registrable Stock
in any other registration shall be deemed to extend until the earlier of the
sale of all Registrable Stock covered thereby and six (6) months after the
effective date thereof.

                  6. Suspension of Registration Statement. The Company may
suspend the availability of any registration statement filed by the Company
referred to in Section 3 and the use of the prospectus included therein if such
suspension is effected in good faith and for valid business reasons (not
including avoidance of the Company's obligations hereunder), including the
acquisition or divestiture of assets, the filing of public reports with the SEC
and during the





                                        9

pendency of material corporate developments. Upon such suspension of a
registration statement by the Company, the Holders shall suspend offers and
sales of Registrable Stock until the Company notifies the Holders that (i)
offers and sales may recommence or (ii) the Company has filed a supplement to
the prospectus or an amendment to such registration statement to update the
disclosure contained therein.

                  7. Furnish Information. It shall be a condition precedent to
the obligations of the Company to take any action pursuant to this Agreement
that the Holders shall furnish to the Company such information regarding
themselves, the Registrable Stock held by them, and the intended method of
disposition of such securities as the Company shall reasonably request and as
shall be required in connection with the action to be taken by the Company.

                  8. Expenses of Registration. All expenses incurred in
connection with each registration pursuant to Section 3 and Section 4 of this
Agreement, excluding underwriters' discounts and commissions and the fees and
expenses of counsel for the selling Holders, but including without limitation
all registration, filing and qualification fees, word processing, duplicating,
printers' and accounting fees (including the expenses of any special audits or
"cold comfort" letters required by or incident to such performance and
compliance), fees of the New York Stock Exchange or listing fees, messenger and
delivery expenses, all fees and expenses of complying with state securities or
blue sky laws, fees and disbursements of counsel for the Company and the fees
and disbursements, in an amount not to exceed $5,000, of one counsel for the
selling Holders (which counsel shall be selected by the Holders holding a
majority in interest of the Registrable Stock being registered), shall be paid
by the Company. The Holders shall bear and pay the underwriting commissions and
discounts applicable to securities offered for their account in connection with
any registrations, filings and qualifications made pursuant to this Agreement.

                  9. Underwriting Requirements. In connection with any
underwritten offering, the Company shall not be required under Section 4 to
include shares of Registrable Stock in such underwritten offering unless the
Holders of such shares of Registrable Stock accept the terms of the underwriting
of such offering that have been agreed upon between the Company and the
underwriters selected by the Company.

                  10. Rule 144 Information. With a view to making available the
benefits of certain rules and regulations of the SEC which may at any time
permit the sale of the Registrable Stock to the public without registration, (a)
at all times after ninety (90) days after any registration statement covering a
public offering of securities of the Company under the Securities Act shall have
become effective, the Company agrees to:

                    (i) make and keep public information available, as those
               terms are understood and defined in Rule 144 under the Securities
               Act;






                                       10

                    (ii) use its best efforts to file with the SEC in a timely
               manner all reports and other documents required of the Company
               under the Securities Act and the Exchange Act; and

                    (iii) furnish to each Holder of Registrable Stock forthwith
               upon request a written statement by the Company as to its
               compliance with the reporting requirements of such Rule 144 and
               of the Securities Act and the Exchange Act, a copy of the most
               recent annual or quarterly report of the Company, and such other
               reports and documents so filed by the Company as such Holder may
               reasonably request in availing itself of any rule or regulation
               of the SEC allowing such Holder to sell any Registrable Stock
               without registration; and

                  (b) at all times during which the Company is neither subject
to the reporting requirements of Section 13 or 15(d) of the Exchange Act, it
will provide, upon the written request of any Holder of Registrable Stock in
written form (as promptly as practicable and in any event within 15 business
days), to any prospective buyer of such stock designated by such Holder, all
information required by Rule 144A(d)(4)(i) of the General Regulations
promulgated by the SEC under the Securities Act. Upon written request of the
Holder, the Company will cooperate with and assist any Holder of Registrable
Stock or any member of the National Association of Securities Dealers, Inc.
system for Private Offerings Resales and Trading through Automated Linkage
("PORTAL") in applying to designate and thereafter maintain the eligibility of
the Registrable Stock for trading through PORTAL.

                  11. Indemnification. In the event any Registrable Stock is
included in a registration statement under this Agreement:

                    (a) The Company shall indemnify and hold harmless each
               Holder, such Holder's directors and officers and each Person, if
               any, who controls such Holder within the meaning of the
               Securities Act, against any losses, claims, damages or
               liabilities, joint or several, to which they may become subject
               under the Securities Act or otherwise, insofar as such losses,
               claims, damages or liabilities (or proceedings in respect
               thereof) arise out of or are based on any untrue or alleged
               untrue statement of any material fact contained in such
               registration statement on the effective date thereof (including
               any prospectus filed under Rule 424 under the Securities Act or
               any amendments or supplements thereto) or arise out of or are
               based upon the omission or alleged omission to state therein a
               material fact required to be stated therein or necessary to make
               the statements therein not misleading, and shall reimburse each
               such Holder, such Holder's directors and officers or controlling
               person for any legal or other expenses reasonably incurred by
               them (but not in excess of expenses incurred in respect of one
               counsel for all of them unless, in the reasonable judgement of an
               indemnified party there is a conflict of interest with another
               indemnified party, in which case the





                                       11

               indemnified parties may be represented by separate counsel) in
               connection with investigating or defending any such loss, claim,
               damage, liability or action; provided, however, that the
               indemnity agreement contained in this Section 10(a) shall not
               apply to amounts paid in settlement of any such loss, claim,
               damage, liability or action if such settlement is effected
               without the consent of the Company (which consent shall not be
               unreasonably withheld); provided, further, that the Company shall
               not be liable to any Holder, such Holder's directors and officers
               or controlling Person in any such case for any such loss, claim,
               damage, liability or action to the extent that it arises out of
               or is based upon an untrue statement or alleged untrue statement
               or omission or alleged omission made in connection with such
               registration statement, preliminary prospectus, final prospectus
               or amendments or supplements thereto, in reliance upon and in
               conformity with written information furnished expressly for use
               in connection with such registration by any such Holder, such
               Holder's directors and officers or controlling Person. Such
               indemnity shall remain in full force and effect regardless of any
               investigation made by or on behalf of any such Holder, such
               Holder's directors and officers or controlling Person, and shall
               survive the transfer of such securities by such Holder. The
               indemnification as provided in this Section 10(a) shall be
               separate from, and in addition to, the indemnification provided
               in the Merger Agreement or the Stock Purchase Agreement.

                    (b) The Holders demanding or joining in a registration
               severally and not jointly shall indemnify and hold harmless the
               Company, each of its directors and officers, each Person, if any,
               who controls the Company within the meaning of the Securities
               Act, and each agent and any underwriter for the Company (within
               the meaning of the Securities Act) against any losses, claims,
               damages or liabilities, joint or several, to which the Company or
               any such director, officer, controlling Person, agent or
               underwriter may become subject, under the Securities Act or
               otherwise, insofar as such losses, claims, damages or liabilities
               (or proceedings in respect thereof) arise out of or are based
               upon any untrue statement or alleged untrue statement of any
               material fact contained in such registration statement on the
               effective date thereof (including any prospectus filed under Rule
               424 under the Securities Act or any amendments or supplements
               thereto) or arise out of or are based upon the omission or
               alleged omission to state therein a material fact required to be
               stated therein or necessary to make the statements therein not
               misleading, in each case to the extent, but only to the extent,
               that such untrue statement or alleged untrue statement or
               omission or alleged omission was made in such registration
               statement, preliminary or final prospectus, or amendments or
               supplements thereto, in reliance upon and in conformity with
               written information furnished by or on behalf of such Holder
               expressly for use in connection with such registration; and each
               such Holder shall reimburse any legal or other expenses
               reasonably incurred by the Company or any such director, officer,
               controlling Person, agent or underwriter (but not in excess of
               expenses incurred in





                                       12

               respect of one counsel for all of them unless, in the reasonable
               judgement of an indemnified party, there is a conflict of
               interest with another indemnified party, in which case the
               indemnified parties may be represented by separate counsel) in
               connection with investigating or defending any such loss, claim,
               damage, liability or action; provided, however, that the
               indemnity agreement contained in this Section 10(b) shall not
               apply to amounts paid in settlement of any such loss, claim,
               damage, liability or action if such settlement is effected
               without the consent of such Holder (which consent shall not be
               unreasonably withheld), and provided, further, that the liability
               of each Holder hereunder shall be limited to the proportion of
               any such loss, claim, damage, liability or expense which is equal
               to the proportion that the net proceeds from the sale of the
               shares sold by such Holder under such registration statement
               bears to the total net proceeds from the sale of all securities
               sold thereunder, but not in any event to exceed the net proceeds
               received by such Holder from the sale of Registrable Stock
               covered by such registration statement.

                    (c) Promptly after receipt by an indemnified party under
               this Section 10(c) of notice of the commencement of any action,
               such indemnified party shall, if a claim in respect thereof is to
               be made against any indemnifying party under this Section, notify
               the indemnifying party in writing of the commencement thereof and
               the indemnifying party shall have the right to participate in and
               assume the defense thereof with counsel selected by the
               indemnifying party and reasonably satisfactory to the indemnified
               party; provided, however, that an indemnified party shall have
               the right to retain its own counsel, with all fees and expenses
               thereof to be paid by such indemnified party (except as provided
               in paragraph (a) and (b) above), and to be apprised of all
               progress in any proceeding the defense of which has been assumed
               by the indemnifying party. The failure to notify an indemnifying
               party promptly of the commencement of any such action shall only
               release the indemnifying party from any of its obligations under
               this Section 11 if, and only to the extent that, such
               indemnifying party is materially prejudiced by such failure, but
               the omission to so notify the indemnifying party will not relieve
               it of any liability that it may have to any indemnified party
               otherwise than under this Section.

                    (d) To the extent any indemnification by an indemnifying
               party is prohibited or limited by law, the indemnifying party, in
               lieu of indemnifying such indemnified party, shall contribute to
               the amount paid or payable by such indemnified party as a result
               of such losses, claims, damages or liabilities in such proportion
               as is appropriate to reflect the relative fault of the
               indemnifying party and indemnified party in connection with the
               actions which resulted in such losses, claims, damages or
               liabilities, as well as any other relevant equitable
               considerations. The relative fault of such indemnifying party and
               indemnified party shall be determined by reference to, among
               other things, whether any action in question, including any
               untrue or alleged untrue





                                       13

               statement of material fact or omission or alleged omission to
               state a material fact, has been made by, or relates to
               information supplied by, such indemnifying party or indemnified
               party, and the parties' relative intent, knowledge, access to
               information and opportunity to correct or prevent such action.
               The amount paid or payable by a party as a result of the losses,
               claims, damages or liabilities referred to above shall be deemed
               to include any legal or other fees or expenses reasonably
               incurred by such party in connection with any investigation or
               proceeding.

                    The parties hereto agree that it would not be just and
               equitable if contribution pursuant to this Section 11(d) was
               determined by pro rata allocation or by any other method of
               allocation which does not take account of the equitable
               considerations referred to in the immediately preceding
               paragraph. No Person guilty of fraudulent misrepresentation
               (within the meaning of Section 11(f) of the Securities Act) shall
               be entitled to contribution from any Person who was not guilty of
               such fraudulent misrepresentation.

                  12. Limitation on Registration Rights. Notwithstanding any
other provisions of this Agreement to the contrary, the Company shall not be
required to register any Registrable Stock under this Agreement with respect to
any demand or demands made by any Holder after fifteen months after the date of
this Agreement.

                  13. No Inconsistent Agreements. The Company agrees that it
will not during the term of this Agreement enter into any agreement with respect
to its securities which is inconsistent with the rights granted to the Holders
under this Agreement.

                  14. Lockup. Each Holder shall, in connection with any
registration of the Company's securities, upon the request of the Company or the
underwriters managing any underwritten offering of the Company's securities,
agree in writing not to effect any sale, disposition or distribution of any
Registrable Stock (other than that included in the registration) without the
prior written consent of the Company or such underwriters, as the case may be,
for such period of time not to exceed one hundred eighty (180) days from the
effective date of such registration as the Company or the underwriters may
specify; provided, however, that all executive officers and directors of the
Company shall also have agreed not to effect any sale, disposition or
distribution of any Registrable Stock under the circumstances and pursuant to
the terms set forth in this Section 14.

                  15. Assignment of Registration Rights. The registration rights
of any Holder under this Agreement with respect to any Registrable Stock may be
assigned to an Affiliate of such Holder; provided, however, that (a) the
assigning Holder shall give the Company written notice at or prior to the time
of such assignment stating the name and address of the assignee and identifying
the securities with respect to which the rights under this Agreement are being





                                       14

assigned; (b) such assignee shall agree in writing, in form and substance
reasonably satisfactory to the Company, to be bound as a Holder by the
provisions of this Agreement; and (c) immediately following such assignment the
further disposition of such securities by such assignee is restricted under the
Securities Act. No assignment of the registration rights of any Holder with
respect to any Registrable Stock in accordance with this Section 15 shall cause
such Registrable Stock to lose such status.

                  16. Binding Effect; Benefit. This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns. Nothing in this Agreement, expressed or implied, is
intended to confer on any Person other than the parties hereto or their
respective successors and assigns any rights, remedies, obligations or
liabilities under or by reason of this Agreement.

                  17. Governing Law; Jurisdiction and Service of Process. This
Agreement shall be governed by, and construed in accordance with, the laws of
the State of New York applicable to contracts executed in and to be performed in
that State. Any legal action or proceeding with respect to this Agreement shall
be brought in the courts of the State of Delaware located in Wilmington or in
the United States District Court for the District of Delaware. By execution and
delivery of this Agreement, each of the parties hereto accepts for itself and in
respect of its property, generally and unconditionally, the jurisdiction of the
aforesaid courts. Each of the parties hereto irrevocably consents to the service
of process of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by certified mail, postage prepaid, to the
party at its address set forth in Section 20.

                  18. Counterparts. This Agreement may be executed and delivered
(including by facsimile transmission) in one or more counterparts, and by the
different parties hereto in separate counterparts, each of which when executed
and delivered shall be deemed to be an original but all of which taken together
shall constitute one and the same agreement.

                  19. Headings. The descriptive headings contained in this
Agreement are included for convenience of reference only and shall not affect in
any way the meaning or interpretation of this Agreement.

                  20. Notices. All notices, requests, claims, demands and other
