     pursuant to such registration statement; provided, however, that in either
     case of (i) or (ii) above, any such securities shall cease to be
     Registrable Securities if the registration rights granted hereunder are not
     transferred in accordance with the provisions of Section 1.11 below.

          (g) The number of shares of "Registrable Securities then outstanding"
     shall be determined by the number of shares of Common Stock issued or

          (h) The term "SEC" shall mean the Securities and Exchange Commission.

     1.2  Demand Registration.

          (a) From and after January 1, 2001, the Holders of at least 66 2/3% of
     the then outstanding Registrable Securities may notify the Company in
     writing that such Holders desire for the Company to cause all or a portion
     of such notifying Holders' Registrable Securities to be registered for sale
     to the public under the Act. Upon receipt of such written request, the
     Company will promptly notify in writing all other Holders of Registrable
     Securities of such request, which Holders shall within twenty days
     following such notice from the Company notify the Company in writing
     whether such persons desire to have Registrable Securities held by them
     included in such offering. The Company will, promptly following the
     expiration of such twenty day period, prepare and file subject to the
     provisions of this Section 1, and use its best efforts to prosecute to
     effectiveness, an appropriate filing with the SEC of a registration
     statement covering such Registrable Securities and the proposed sale or
     distribution thereof under the Act.

          (b) Notwithstanding anything in this Section 1.2 to the contrary, the
     Company shall not be obligated to prepare or file any registration
     statement pursuant to this Section 1.2 or to prepare or file any amendment
     or supplement thereto, at any time when the Company delivers a certificate
     signed by the Company's Chief Executive Officer or Chairman of the Board
     stating that in the good faith judgment of the Board of Directors of the
     Company that

<PAGE>   3

     the filing thereof at the time requested, or the offering of securities
     pursuant thereto (i) would materially adversely affect a pending or
     proposed public offering of the Company's securities, or an acquisition,
     merger, recapitalization, consolidation, reorganization or similar
     transaction, negotiations, discussions or pending proposals with respect
     thereto or (ii) would materially adversely affect the business or prospects
     of the Company in view of the disclosures that may be required thereby of
     information about the business, assets, liabilities or operations of the
     Company not theretofore disclosed; provided, however, that the filing of a
     registration statement, or any supplement or amendment thereto, by the
     Company may be deferred pursuant to this Section 1.2 for no longer than 180
     days (but only once in every twelve month period) after the delivery of
     such demand notice.

          (c) Notwithstanding anything in this Section 1.2 to the contrary: (i)
     the Company shall not be required to effect the registration of the
     Registrable Securities pursuant to this Section 1.2 more than one time in
     any twelve month period and no more than three times in the aggregate; and
     (ii) the Company shall not be required to effect any such registration
     unless at least $5 million of Registrable Securities are to be sold in such
     registration (with such amount being determined based on the market price
     of the Common Stock on the date of the initiating Holder(s) request). If
     any registration pursuant to this Section 1.2 is in the form of an
     underwritten offering, the Company will select and obtain the investment
     banker or investment bankers and manager or managers that will administer
     the offering, which investment bankers must offer terms which are
     reasonably competitive in the marketplace for similar size companies and
     similar offerings. The Company shall (together with all Holders proposing
     to distribute Registrable Securities through such underwriting) enter into
     an underwriting agreement, containing usual and customary terms, with the
     managing underwriter selected for such underwriting. If any holder of
     Registrable Securities disapproves of the terms of the underwriting, such
     person may elect to withdraw therefrom by written notice to the Company and
     the managing underwriter. The Registrable Securities so withdrawn shall
     also be withdrawn from registration.

          (d) If any registration statement under this Section 1.2 is not
     declared effective (except as a result of Holders withdrawing Registrable
     Securities), then the holders of Registrable Securities may request an
     additional registration under this Section 1.2.

          (e) No registrations effected under this Section 1.2 shall relieve the
     Company of its obligations to effect any registrations under, and pursuant
     to the terms of, Sections 1.3 and 1.4 hereof.

     1.3  S-3 Registrations.

          (a) Once the Company is eligible to effect a registration of its
     securities under Form S-3 (or successor form), the Holders will have the
     right to request and have effected (but only one registration per twelve
     month period) registrations of Registrable Securities on Form S-3 as long
     as the aggregate proposed offering price is not less $3 million for any
     such registration. Upon written request of Holders holding at least $3
     million of Registrable Securities, the Company will promptly notify in
     writing all other Holders of Registrable Securities of such request, which
     Holders shall within twenty days following such notice from the Company
     notify the Company in writing whether such persons desire to have
     Registrable Securities held by them included in such offering. Following
     the expiration of such twenty day period, the Company will use all
     reasonable efforts to cause the registration of all Registrable Securities
     proposed to be included in the offering on Form S-3 or such successor form
     to the extent so requested. Notwithstanding the above, the Company shall
     not be required under this Section 1.3 to include any of the Holders'
     Registrable Securities in any offering on Form S-3 which involves an
     underwriting unless such Holders accept the terms of such underwriting as
     agreed upon between the Company and the underwriters selected by it.
     Registrations effected pursuant to this Section 1.3 shall not be counted as
     requests for registration effected pursuant to Sections 1.2.

          (b) Notwithstanding anything in this Section 1.3 to the contrary, the
     Company shall not be obligated to prepare or file any registration
     statement pursuant to this Section 1.3 or to prepare or file any amendment
     or supplement thereto, at any time when the Company delivers a certificate
     signed by the Company's Chief Executive Officer or Chairman of the Board
     stating that in the good faith judgment of the Board of Directors of the
     Company that the filing thereof at the time requested, or the offering of
     securities pursuant thereto (i) would materially adversely affect a pending
     or proposed public offering of the Company's securities, or an acquisition,
     merger, recapitalization, consolidation, reorganization or similar
     transaction, negotiations, discussions or pending proposals with respect
     thereto or (ii) would materially adversely affect the business or prospects
     of the Company in view of the disclosures that may be required thereby of
     information about the business, assets, liabilities or operations of the
     Company not theretofore disclosed; provided, however, that the filing of a
     registration statement, or any supplement or amendment thereto, by the
     Company may be deferred pursuant to this Section 1.3 for no longer than 180
     days (but only once in every twelve month period) after the delivery of
     such demand notice.

     1.4 Piggyback Registration. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for stockholders other than the Holders) any Common Stock or
other securities under the Act in connection with the public offering of such
securities solely for cash (other than an initial public offering, registration
relating solely to the sale of securities to participants in a Company stock
option, stock purchase or similar employee benefit plan, a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities (including Form S-4 or any form substitution thereof) or
a registration in which the only Common Stock being registered is Common Stock
issuable upon

<PAGE>   5

conversion of debt securities which are also being registered or a SEC Rule 145
transaction), the Company shall, at such time, promptly give each Holder written
notice of such registration. Upon the written request of each Holder given
within twenty days after mailing of such notice by the Company, the Company
shall, subject to the provisions of Section 1.8, use all reasonable efforts to
cause to be registered under the Act and any applicable state securities laws
all of the Registrable Securities that each such Holder has requested to be
registered.

     1.5 Obligations of the Company. Whenever under this Section 1 the Company
effects the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible,:

         (a) Prepare and file with the SEC on any appropriate form a
     registration statement with respect to the Registrable Securities proposed
     to be registered and use its best efforts to cause such registration
     statement to become effective, and, upon the request of the Holders of a
     majority of the Registrable Securities registered thereunder, keep such
     registration statement effective for a period of up to one hundred twenty
     (120) days or, if earlier, until the distribution contemplated in the
     Registration Statement has been completed;

         (b) Unless such registration is a firm commitment underwriting, prepare
     and file with the SEC such amendments (including post-effective amendments)
     and supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective and to comply with the provisions of the Act with
     respect to the disposition of all Registrable Securities and other
     securities covered by such registration statement for a period of 180 days.

         (c) Furnish to the Holders such numbers of copies of a prospectus,
     including a preliminary prospectus, in conformity with the requirements of
     the Act, and such other documents as they may reasonably request in order
     to facilitate the disposition of Registrable Securities owned by them.

         (d) Use its best efforts to register or qualify all Registrable
     Securities and other securities covered by such registration statement
     under such other securities or "blue sky" laws of such jurisdictions as the
     underwriter or such sellers shall reasonably request and do any and all
     other acts and things as may be reasonably necessary to consummate the
     disposition in such jurisdictions of the Registrable Securities covered by
     such registration statement, except that the Company shall not for any such
     purpose be required to qualify generally to do business as a foreign
     corporation in any jurisdiction wherein it is not so qualified, or to
     subject itself to taxation in respect of doing business in any such
     jurisdiction, or to consent to general service of process in any such
     jurisdiction.

<PAGE>   6

         (e) Immediately notify each seller of Registrable Securities covered by
     such registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the 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 the light of the
     circumstances then existing or if it is necessary, in the opinion of
     counsel to the Company, to amend or supplement such prospectus to comply
     with law, and at the request of any such seller prepare and to send such
     seller a reasonable number of copies of a supplement to or any amendment of
     such prospectus as may be necessary so that, as thereafter delivered to the
     purchasers of such Registrable Securities, such prospectus shall not
     include any untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances then existing and
     shall otherwise comply in all material respects with law and so that such
     prospectus, as amended or supplemented, will comply with law.

         (f) Otherwise use its best efforts to comply with all applicable rules
     and regulations of the SEC, any make available to its securityholders, as
     soon as reasonably practicable, an earnings statement covering the period
     of at least twelve (12) months, beginning with the first month of the first
     fiscal quarter after the effective date of such registration statement,
     which earnings statement shall satisfy the provisions of Section 11 (a) of
     the Act.

         (g) In the event of any underwritten public offering, enter into and
     perform its obligations under an underwriting agreement, in usual and
     customary form, with the managing underwriter of such offering. Each Holder
     participating in such underwriting shall also enter into and perform its
     obligations under such an agreement.

         (h) Cause all such Registrable Securities registered pursuant hereunder
     to be listed on each securities exchange or automated trading system on
     which similar securities issued by the Company are then listed.

         (i) Provide a transfer agent and registrar for all Registrable
     Securities registered pursuant hereunder and a CUSIP number for all such
     Registrable Securities, in each case not later than the effective date of
     such registration.

     1.6 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

<PAGE>   7

     1.7 Expenses of Registration. All expenses incurred in connection with
registrations, filings or qualifications pursuant to this Section 1 in
connection with one demand registration, all piggyback registrations and all S-3
registrations including, without limitation, all registration, filing and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company and the reasonable fees and expenses of one counsel for
the selling Holders (as a group) (but excluding underwriter's commissions and
fees and any fees of others employed by a selling Holder) shall be borne by the
Company.

     1.8  Underwriting Requirements; Cut-backs.

          (a) In connection with any offering involving an underwriting of
     shares of the Company's capital stock, the Company shall not be required to
     include any Holders' Registrable Securities in such underwriting unless
     they accept the terms of the underwriting as agreed upon between the
     Company and the underwriters selected by it (or by other persons entitled
     to select the underwriters), and then only in such quantity as the
     underwriters determine in their sole discretion will not materially
     jeopardize or in any way reduce the success of the offering by the Company
     (with the securities being eliminated as provided in (b) below).

          (b) The Company has previously granted "piggyback" registration rights
     to certain of its securityholders (the "Other Holders"). Notwithstanding
     anything in this Section 1 to the contrary, in the event of any request for
     registration hereunder, the Company shall provide each Other Holder the
     notice required with respect to their registration rights and will allow
     such Other Holders to participate in any such registration to the extent of
     such registration rights; it being acknowledged and agreed that if the
     total amount of securities, including Registrable Securities, requested by
     Holders and Other Holders to be included in such offering exceeds the
     amount of securities that the underwriters determine in their sole
     discretion is compatible with the success of the offering (excluding any
     securities to be offered by the Company), then the Company shall be
     required to include in the offering only that number of such securities,
     including Registrable Securities, which the underwriters determine in their
     sole discretion will not jeopardize the success of the offering (the
     securities so included to be apportioned pro rata among the selling Holders
     and Other Holders according to the total amount of securities entitled to
     be included therein owned by each selling Holder and Other Holder or in
     such other proportions as shall mutually be agreed to by such selling
     Holders and Other Holders).

     1.9  Delay of Registration. No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any registration by the
Company of any securities as a result of any controversy that might arise with
respect to the interpretation or implementation of this Section 1.

     1.10 Indemnification. In the event any Registrable Securities are included
in a registration statement under this Section 1:

          (a) To the extent permitted by law, the Company will indemnify and
     hold harmless each Holder, any underwriter (as defined in the Act) for such
     Holder and each person, if any,

<PAGE>   8

     who controls such Holder or underwriter within the meaning of the Act or
     the 1934 Act against any losses, claims, damages, or liabilities, joint or
     several) to which they may become subject under the Act, the 1934 Act or
     other federal or state law, insofar as such losses, claims, damages, or
     liabilities (or actions in respect thereof) arise out of or are based upon
     any of the following statements, omissions or violations (collectively a
     "Violation"): (i) any untrue statement or alleged untrue statement of a
     material fact contained in such registration statement, including any
     preliminary prospectus or final prospectus contained therein or any
     amendments or supplements thereto, (ii) 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, or (iii) any violation or
     alleged violation by the Company of the Act, the 1934 Act, any state
     securities law or any rule or regulation promulgated under the, the 1934
     Act or any state securities law; and, subject to subsection 1.10 (c) below,
     the Company will pay to each such Holder, underwriter or controlling
     person, as incurred, any legal or other expenses reasonably incurred by
     them in connection with investigating or defending any such loss, claim,
     damage, liability, or action; provided, however, that the indemnity
     agreement contained in this subsection 1.10(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 reasonably delayed or withheld), nor shall the Company
     be liable 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 a Violation
     which occurs in reliance upon and in conformity with written information
     furnished expressly for use in connection with such registration by any
     such Holder, underwriter or controlling person.

          (b) To the extent permitted by law, each selling Holder will indemnify
     and hold harmless the Company, each of its directors, each of its officers
     who has signed the registration statement, each person, if any, who
     controls the Company within the meaning of the Act, any underwriter, any
     other Holder selling securities in such registration statement and any
     controlling person of any such underwriter or other Holder, and any agent
     of the Company, against any losses, claims, damages, or liabilities joint
     or several) to which any of the foregoing persons may become subject, under
     the Act, the 1934 Act or other federal or state law, insofar as such
     losses, claims, damages, or liabilities (or actions in respect thereto)
     arise out of or are based upon any Violation, in each case to the extent
     (and only to the extent) that such Violation occurs in reliance upon and in
     conformity with written information furnished by such Holder expressly for
     use in connection with such registration; and each such Holder will pay, as
     incurred, any legal or other expenses reasonably incurred by any person
     intended to be indemnified pursuant to this subsection 1.10(b), in
     connection with investigating or defending any such loss, claim, damage,
     liability, or action; provided, however, that the indemnity agreement
     contained in this subsection 1.10(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 the Holder, which consent
     shall not be reasonably withheld; provided, that, in no event shall any
     indemnity under this subsection 1.10(b) exceed the net proceeds from the
     offering received by such Holder.

          (c) Promptly after receipt by an indemnified party under this Section
     1.10 of notice of the commencement of any action (including any
     governmental action), such

<PAGE>   9

     indemnified party will, if a claim in respect thereof is to be made against
     any indemnifying party under this Section 1.10, deliver to the indemnifying
     party a written notice of the commencement thereof and the indemnifying
     party shall have the right to participate in, and, to the extent the
     indemnifying party so desires, jointly with any other indemnifying party
     receiving similar notice, to assume the defense thereof with counsel
     reasonably satisfactory to the parties; provided, however, that an
     indemnified party (together with all other indemnified party which may be
     represented without conflict by one counsel) shall have the right to retain
     one separate counsel, with the fees and expenses to be paid by the
     indemnifying party, if representation of such indemnified party by the
     counsel retained by the indemnifying party would be inappropriate due to
     actual or potential differing interests between such indemnified party and
     any other party represented by such counsel in such proceeding; otherwise,
     the indemnified party shall be responsible for the fees and expenses of its
     counsel. The failure to deliver written notice to the indemnifying party
     within a reasonable time of the commencement of any such action, if
     prejudicial to its ability to defend such action, shall relieve such
     indemnifying party of any liability to the indemnified party under this
     Section 1.10 with respect to such action, but not with respect to any other
     action.

          (d) Except as provided in the last sentence of subsection 1.10(c)
     above, if the indemnification provided for in this Section 1.10 is held by
     a court of competent jurisdiction to be unavailable to an indemnified party
     with respect to any loss, liability, claim, damage, or expense referred to
     herein, then the indemnifying party, in lieu of indemnifying such
     indemnified party hereunder, shall contribute to the amount paid or payable
     by such indemnified party as a result of such loss, liability, claim,
     damage, or expense in such proportion as is appropriate to reflect the
     relative fault of the indemnifying party on the one hand and of the
     indemnified party on the other in connection with the statements or
     omissions that resulted in such loss, liability, claim, damage, or expense
     as well as any other relevant equitable considerations. The relative fault
     of the indemnifying party and of the indemnified party shall be determined
     by reference to, among other things, whether the untrue or alleged untrue
     statement of a material fact or the omission to state a material fact
     relates to information supplied by the indemnifying party or by the
     indemnified party and the parties relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission.

          (e) Notwithstanding the foregoing, to the extent that the provisions
     on indemnification and contribution contained in the underwriting agreement
     entered into in connection with the underwritten public offering are in
     conflict with the foregoing provisions, the provisions in the underwriting
     agreement shall control.

          (f) The obligations of the Company and Holders under this Section 1.10
     shall survive the completion of any offering of Registrable Securities
     pursuant to a registration statement under this Section 1.

     1.11 Reports Under the 1934 Act. With a view to making available to the
Holders the benefits of Rule 144 promulgated under the Act ("Rule 144") and any
other rule or regulation of the SEC that may at any time permit a Holder to sell
securities of the Company to the public without

<PAGE>   10

registration or pursuant to a registration on Form S-3, the Company agrees to:

          (a) make and keep public information available, as those terms are
understood and defined in Rule 144, at all times after ninety (90) days after
the effective date of the IPO;

          (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

          (c) furnish to any Holder, so long as the Holder owns any Registrable
Securities, promptly upon request (i) a written statement by the Company that it
has complied with the reporting requirements of Rule 144 (at any time after
ninety (90) days after the effective date of the first registration statement
filed by the Company), the Act and the 1934 Act (at any time after it has become
subject to such reporting requirements), or that it qualifies as a registrant
whose securities may be resold pursuant to Form S-3 (at any time after it so
qualifies), (ii) a copy of the most recent annual or quarterly report of the
Company and such other reports and documents so filed by the Company, and (iii)
such other information as may be reasonably requested in availing any Holder of
any rule or regulation of the SEC that permits the selling of any such
securities without registration or pursuant to such form.

     1.12 Assignment of Registration Rights. The registration rights of the
Holders under this Section 1 may be assigned (but only with all related
obligations) by a Holder to a transferee or assignee of such securities who
purchases from such Holder at least 10,000 shares of Registrable Securities
(subject to appropriate adjustment for stock splits, stock dividends,
combinations and other recapitalizations), provided: (a) the Company is within a
reasonable time after such transfer, furnished with written notice of the name
and address of such transferee or assignee and the securities with respect to
which such registration rights are being assigned; (b) such transferee or
assignee agrees in writing to be bound by and subject to the terms and
conditions of this Agreement, including without limitation the provisions of
Section 1. 13 below; and (c) such assignment shall be effective only if
immediately following such transfer the further disposition of such securities
by the transferee or assignee is restricted under the Act.

     1.13 Lock-up Agreement. Each Holder hereby agrees that if requested by the
Company or the underwriters in any underwritten offering, such Holder shall not,
for the period of not more than 180 days (as specified by the managing
underwriter) after the effective date of an IPO (or any other underwritten
public offering of shares of Common Stock, if requested by the managing
underwriter), without the prior written approval of the Company or such
underwriters (as the case may be), directly or indirectly, sell, offer to sell,
contract to sell (including without limitation, any short sale), grant any
option to purchase or otherwise transfer or dispose of any shares of Common
Stock underlying the Series C Preferred Stock legally or beneficially owned by
such Holder; provided, however, in the event of an initial public offering of
Common Stock, no request shall be necessary, with the consent of such Holder to
the above provisions in this Section 1.13 being hereby granted and accepted,
provided that if the managing underwriter in such initial public offering
requests that Holder execute and deliver a lock-up letter, Holder agrees to do
so, which lock-up letter shall be in such managing underwriter's customary form.
In order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and

<PAGE>   11

the shares or securities of every other person subject to the foregoing
restriction) until the end of such period. Notwithstanding the foregoing, the
provisions of this Section 1.13 shall only be applicable to the Holders if all
officers and directors and greater than two percent (2%) stockholders of the
Company enter into similar agreements.

     1.14 Termination of Registration Rights. Notwithstanding anything in this
Section 1 to the contrary, no Holder shall be entitled to exercise any right
provided for in this Section 1: (i) at any time more than four (4) years
following the date of the Company's IPO or (ii) at such time as such Holder is
able to sell all of such Holder's Registrable Securities in a single three-month
period in compliance with Rule 144.

     1.15 Limitations on Subsequent Registration Rights. From and after the date
of this Agreement and until Holder's registration rights terminate pursuant to
Section 1.14 above, the Company shall not, without the prior written consent of
the Holders of a majority of the Registerable Securities, enter into any
agreement with any holder or prospective holder of any securities of the Company
that would grant to such holder or prospective holder registration rights which
are superior to those granted to the Holders hereunder (although pari passu
rights will be permissible).

2.   Covenants of the Company

     2.1 Delivery of Financial Statements. The Company shall deliver to each
Holder of a least 20,000 shares Registrable Securities (other than a Holder
reasonably deemed by the Company to be a competitor of the Company):

         (a) as soon as practicable, but in any event within ninety (90) days
     after the end of each fiscal year of the Company, an income statement for
     such fiscal year, a balance sheet of the Company and statement of
     stockholder's equity as of the end of such year, and a statement of cash
     flows for such year, such year-end financial reports to be in reasonable
     detail, prepared in accordance with generally accepted accounting
     principles ("GAAP"), and audited and certified by an independent public
     accounting form of nationally recognized standing selected by the Company;

         (b) as soon as practicable, but in any event within forty-five (45)
     days after the end of each of the first three (3) quarters of each fiscal
     year of the Company, an unaudited income statement, statement of cash flows
     for such fiscal quarter and an unaudited balance sheet as of the end of
     such fiscal quarter;

         (c) within thirty (30) days of the end of each month, an unaudited
     income statement and a statement of cash flows and balance sheet for and as
     of the end of such month, in reasonable detail;

         (d) as soon as practicable, but in any event thirty (30) days prior to
     the end of each fiscal year, a budget and business plan for the next fiscal
     year, prepared on a monthly basis, including balance sheets, income
     statements and statements of cash flows for such months, and, as soon as
     prepared, any other budgets or revised budgets prepared by the Company; and

<PAGE>   12

         (e) with respect to the financial statements called for in subsections
     (b) and (c) of this Section 2.1, an instrument executed by the Chief
     Financial Officer, Chief Executive Officer or President of the Company
     certifying that such financials were prepared in accordance with GAAP
     consistently applied with prior practice for earlier periods (with the
     exception of footnotes that may be required by GAAP) and fairly present the
     financial condition of the Company and its results of operation for the
     period specified, subject to year-end audit adjustment. provided that the
     foregoing shall not restrict the right of the Company to change its
     accounting principles consistent with GAAP, if the Board of Directors
     determines that it is in the best interest of the Company to do so.

     2.2 Inspection. The Company shall permit each Holder of at least 20,000
shares of Registrable Securities, except for a Holder reasonably deemed by the
Company to be a competitor of the Company, at such Holder's expense, to visit
and inspect the Company's properties, to examine its books of account and
records and to discuss the Company's affairs, finances and accounts with its
officers, all at such reasonable times as may be requested by such Holder;
provided, however, that the Company shall not be obligated pursuant to this
Section 2.2 to provide access to any information which it reasonably considers
to be a trade secret or similar confidential information.

     2.3 Termination of Covenants. The covenants set forth in Section 2.1 and
Section 2.2 above shall terminate as to each Holder and be of no further force
or effect on the earlier of (a) immediately prior to the consummation of an IPO
or (b) when the Company first becomes subject to the periodic reporting
requirements of Sections 13 or 15(d) of the Exchange Act.

     2.4 Subsequent Issuances of Preferred Stock. The Company shall not issue
any shares of Series A Preferred Stock or Series B Preferred Stock, or other
securities or rights convertible in Series A Preferred Stock or Series B
Preferred Stock, as the case may be.

3.   Miscellaneous

at such party's address as set forth below or on Exhibit A hereto, or as
subsequently modified by written notice.

     3.4 Severability. If one or more provisions of this Agreement are held to
be unenforceable under applicable law, the parties agree to renegotiate such
provision in good faith. In the event that the parties cannot reach a mutually
agreeable and enforceable replacement for such provision, the (a) such provision
shall be excluded from this Agreement, (b) the balance of the Agreement shall be
interpreted as if such provision were so excluded and (c) the balance of the
Agreement shall be enforceable in accordance with its terms.

     3.5 Governing Law. This Agreement and all acts and transactions pursuant
hereto shall be governed, construed and interpreted in accordance with the laws
of the State of Delaware, without giving effect to principles of conflicts of

are used for convenience only and are not to be considered in construing or
interpreting this Agreement.

     3.7 Aggregation of Stock. All shares of Series C Preferred Stock held or

purpose of determining the availability of any rights under this Agreement.

     3.8 Expenses. If any action at law or in equity is necessary to enforce or
interpret the terms of this Agreement, the prevailing party shall be entitled to
reasonable attorneys' fees, cost and necessary disbursements in addition to any
other relief to which such party may be entitled.

any) constitutes the full and entire understanding and agreement between the
parties with regard to the subjects hereof and thereof.

     3.10 Counterparts. This Agreement may be executed in two or more

together shall constitute one and the same instrument.

                               REGISTRATION RIGHTS

1. Registration Rights. Mobility Electronics, Inc., a Delaware corporation (the
"Company"), covenants and agrees with you as follows:

         1.1 Definitions. For purposes of this Exhibit E:

                  The term "Act" means the Securities Act of 1933, as amended.

                  The term "Holder" means any person owning or having the right
         to acquire Registrable Securities or any assignee thereof in accordance
         with Section 1.11 hereof.

                  The term "1934 Act" shall mean the Securities Exchange Act of
         1934, as amended.

                  The term "Public Company" means a corporation which has a
         class of equity securities registered pursuant to Section 12 of the
         1934 Act, or which is required to file periodic reports pursuant to
         Section 15(d) of the 1934 Act.

                  The term "register," "registered," and "registration" refer to
         a registration effected by preparing and filing a registration
         statement or similar document in compliance with the Act, and the
         declaration or ordering of effectiveness of such registration statement
         or document.

                  The term "Registrable Securities" means (i) the shares of
         Common Stock issued or issuable upon the conversion of the Series D
         Stock and (ii) any Common Stock issued as (or issuable upon the
         conversion or exercise of any warrant, right or other security which is
         issued as) a dividend or other distribution with respect to, or in
         exchange for or in replacement of the shares referenced in (i) above,
         excluding in all cases, however, any Registrable Securities (I) sold by
         a person in a transaction in which his rights under this Section 1 are
         not assigned (II) registered under the Act, the registration statement
         in connection therewith has been declared effective, and such shares
         have been disposed by such holder pursuant to such registration
         statement; provided, however, that in either case of (i) or (ii) above,
         any such securities shall cease to be Registrable Securities if the
         registration rights granted hereunder are not transferred in accordance
         with the provisions of Section 1.11 below.

                  The number of shares of "Registrable Securities then
         outstanding" shall be determined by the number of shares of Common
         Stock issued or issuable upon conversion of the Series D Stock.

                  The term "SEC" shall mean the Securities and Exchange
         Commission.

                  The term "Series D Stock" means the Series D Preferred Stock,
         par value $0.01 per share, of the Company.

                  All other capitalized terms used herein which are not defined
         herein shall have the meaning given elsewhere in this Agreement.

1.2 Demand Registration.

                  (a) From and after March 1, 2001, the Holders of at least 66
         2/3% of the then outstanding Registrable Securities may notify the
         Company in writing that such Holders desire for the Company to cause
         all or a portion of such notifying Holders' Registrable Securities to
         be registered for sale to the public under the Act. Upon receipt of
         such written request, the Company will promptly notify in writing all
         other Holders of Registrable Securities of such request, which Holders
         shall within twenty days following such notice from the Company, notify
         the Company in writing whether such persons desire to have Registrable
         Securities held by them included in such offering. The Company will,
         promptly following the expiration of

                                      A-1
<PAGE>   2

         such twenty day period, prepare and file subject to the provisions of
         this Section 1, and use its best efforts to prosecute to effectiveness,
         an appropriate filing with the SEC of a registration statement covering
         such Registrable Securities and the proposed sale or distribution
         thereof under the Act.

                  (b) Notwithstanding anything in this Section 1.2 to the
         contrary, the Company shall not be obligated to prepare or file any
         registration statement pursuant to this Section 1.2, or to prepare or
         file any amendment or supplement thereto, at any time when the Company,
         in the good faith judgment of its Board of Directors, reasonably
         believes that the filing thereof at the time requested, or the offering
         of securities pursuant thereto, (i) would materially adversely affect a
         pending or proposed public offering of the Company's securities, or an
         acquisition, merger, recapitalization, consolidation, reorganization or
         similar transaction, negotiations, discussions or pending proposals
         with respect thereto or (ii) would materially adversely affect the
         business or prospects of the Company in view of the disclosures that
         may be required thereby of information about the business, assets,
         liabilities or operations of the Company not theretofore disclosed;
         provided, however, that the filing of a registration statement, or any
         supplement or amendment thereto, by the Company may be deferred
         pursuant to this Section 1.2 for no longer than 180 days (but only once
         in every twelve month period) after the delivery of such demand notice.

                  (c) Notwithstanding anything in this Section 1.2 to the
         contrary: (i) the Company shall not be required to effect the
         registration of the Registrable Securities pursuant to this Section 1.2
         more than one time; and (ii) the Company shall not be required to
         effect any such registration unless at least $5 million of Registrable
         Securities are to be sold in such registration (with such amount being
         determined based on the market price of the Common Stock on the date of
         the initiating Holder(s) request). If any registration pursuant to this
         Section 1.2 is in the form of an underwritten offering, the Company
         will select and obtain the investment banker or investment bankers and
         manager or managers that will administer the offering, which investment
         bankers must offer terms which are reasonably competitive in the
         marketplace for similar size companies and similar offerings. The
         Company shall (together with all Holders proposing to distribute
         Registrable Securities through such underwriting) enter into an
         underwriting agreement, containing usual and customary terms, with the
         managing underwriter selected for such underwriting. If any holder of
         Registrable Securities disapproves of the terms of the underwriting,
         such person may elect to withdraw therefrom by written notice to the
         Company and the managing underwriter. The Registrable Securities so
         withdrawn shall also be withdrawn from registration.

                  (d) If any registration statement under this Section 1.2 is
         not declared effective (except for the reasons specified in Section 1.9
         below and except as a result of Holders withdrawing Registrable
         Securities), then the holders of Registrable Securities may request an
         additional registration under this Section 1.2.

                  (e) No registrations effected under this Section 1.2 shall
         relieve the Company of its obligations to effect any registrations
         under, and pursuant to the terms of, Sections 1.3 and 1.4 hereof.

         1.3 S-3 Registrations.

                  (a) Once the Company is eligible to effect a registration of
         its securities under Form S-3 (or successor form), the Holders will
         have the right to request and have effected (but only one registration
         per twelve month period) registrations of Registrable Securities on
         Form S-3 as long as the aggregate proposed offering price is not less
         $3 million for any such registration. Upon written request of Holders
         holding at least $3 million of Registrable Securities, the Company will
         promptly notify in writing all other Holders of Registrable Securities
         of such request, which Holders shall within twenty days following such
         notice from the Company, notify the Company in writing whether such
         persons desire to have Registrable Securities held by them included in
         such offering. Following the expiration of such twenty day period, the
         Company will use all reasonable efforts to cause the registration of
         all Registrable Securities proposed to be included in the offering on
         Form S-3 or such successor form to the extent so requested.
         Notwithstanding the above, the Company shall not be required under this
         Section 1.3 to include any of the Holders' Registrable Securities in
         any offering on Form S-3 which involves an underwriting unless such
         Holders accept the terms of such underwriting as agreed upon between
         the Company and the underwriters selected by it.

                  (b) Notwithstanding anything in this Section 1.3 to the
         contrary, the Company shall not be obligated to prepare or file any
         registration statement pursuant to this Section 1.3 or to prepare or
         file any amendment or supplement thereto, at any time when the Company,
         in the good faith judgment of its Board of Directors, reasonably
         believes that the filing thereof at the time requested, or the offering
         of securities pursuant thereto, (i) would materially adversely affect a
         pending or proposed public offering of the Company's securities, or an
         acquisition, merger, recapitalization, consolidation, reorganization or
         similar transaction, negotiations, discussions or pending proposals
         with respect thereto or (ii) would materially adversely affect the
         business or prospects of the Company in view of the disclosures that
         may be required thereby of information about the business, assets,
         liabilities or operations of the Company not theretofore disclosed;
         provided, however, that the filing of a registration statement, or any
         supplement or amendment thereto, by the Company may be deferred
         pursuant to this Section 1.3 for no longer than 180 days (but only once
         in every twelve month period) after the delivery of such demand notice.

         1.4 Piggyback Registration. If (but without any obligation to do so)
the Company proposes to register (including for this purpose a registration
effected by the Company for stockholders other than the Holders) any of its
Common Stock or other securities under the Act in connection with the public
offering of such securities solely for cash (other than an initial public
offering, registration relating solely to the sale of securities to participants
in a Company stock option, stock purchase or similar employee benefit plan, a
registration on any form which does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of the Registrable Securities (including Form S-4 or any form
substitution thereof) or a registration in which the only Common Stock being
registered is Common Stock issuable upon conversion of debt securities which are
also being registered or a SEC Rule 145 transaction), the Company shall, at such
time, promptly give each Holder written notice of such registration. Upon the
written request of each Holder given within twenty days after mailing of such
notice by the Company, the Company shall, subject to the provisions of Section
1.8, use all reasonable efforts to cause to be registered under the Act and any
applicable state securities laws all of the Registrable Securities that each
such Holder has requested to be registered.

         1.5 Obligations of the Company. Whenever under this Section 1 the
Company effects the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                  (a) Prepare and file with the SEC on any appropriate form a
         registration statement with respect to the Registrable Securities
         proposed to be registered and use its best efforts to cause such
         registration statement to become effective;

                  (b) Unless such registration is a firm commitment
         underwriting, prepare and file with the SEC such amendments (including
         post-effective amendments) and supplements to such registration
         statement and the prospectus used in connection therewith as may be
         necessary to keep such registration statement effective and to comply
         with the provisions of the Act with respect to the disposition of all
         Registrable Securities and other securities covered by such
         registration statement for a period of 180 days.

                  (c) Furnish to the Holders such numbers of copies of a
         prospectus, including a preliminary prospectus, in conformity with the
         requirements of the Act, and such other documents as they may
         reasonably request in order to facilitate the disposition of
         Registrable Securities owned by them.

                  (d) Use its best efforts to register or qualify all
         Registrable Securities and other securities covered by such
         registration statement under such other securities or "blue sky" laws
         of such jurisdictions as the underwriter or such sellers (not to exceed
         ten jurisdictions) shall reasonably request and do any and all other
         acts and things as may be reasonably necessary to consummate the
         disposition in such jurisdictions of the Registrable Securities covered
         by such registration statement, except that the Company shall not for
         any such purpose be required to qualify generally to do business as a
         foreign corporation in any jurisdiction wherein it is not so qualified,
         or to subject itself to taxation in respect of doing business in any
         such jurisdiction, or to consent to general service of process in any
         such jurisdiction.

                  (e) Immediately notify each seller of Registrable Securities
         covered by such registration statement, at any time when a prospectus
         relating thereto is required to be delivered under the Act, of the
         happening of any event as a result of which the prospectus included in
         such registration statement, as then

                                      A-3
<PAGE>   4

         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 the light of the
         circumstances then existing or if it is necessary, in the opinion of
         counsel to the Company, to amend or supplement such prospectus to
         comply with law, and at the request of any such seller prepare and
         deliver to such seller a reasonable number of copies of a supplement to
         or any amendment of such prospectus as may be necessary so that, as
         thereafter delivered to the purchasers of such Registrable 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 the light of
         the circumstances then existing and shall otherwise comply in all
         material respects with law and so that such prospectus, as amended or
         supplemented, will comply with law.

                  (f) Otherwise use its best efforts to comply with all
         applicable rules and regulations of the SEC, any make available to its
         security holders, as soon as reasonably practicable, an earnings
         statement covering the period of at least twelve (12) months, beginning
         with the first month of the first fiscal quarter after the effective
         date of such registration statement, which earnings statement shall
         satisfy the provisions of Section 11 (a) of the Act.

                  (g) In the event of any underwritten public offering, enter
         into and perform its obligations under an underwriting agreement, in
         usual and customary form, with the managing underwriter of such
         offering. Each Holder participating in such underwriting shall also
         enter into and perform its obligations under such an agreement.

                  (h) Notify each Holder of Registrable Securities covered by
         such registration statement at any time when a prospectus relating
         thereto is required to be delivered under the 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 a material fact required to be
         stated therein or necessary to make the statements therein not
         misleading in the light of the circumstances then existing.

                  (i) Cause all such Registrable Securities registered pursuant
         hereunder to be listed on each securities exchange or automated trading
         system on which similar securities issued by the Company are then
         listed.

                  (j) Provide a transfer agent and registrar for all Registrable
         Securities registered pursuant hereunder and a CUSIP number for all
         such Registrable Securities, in each case not later than the effective
         date of such registration.

         1.6 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

         1.7 Expenses of Registration. All expenses incurred in connection with
registrations, filings or qualifications pursuant to this Section 1, in
connection with one demand registration, all piggyback registrations and all S-3
registrations including, without limitation, all registration, filing and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company (but excluding underwriter's commissions and fees and
any fees of others employed by a selling Holder) shall be borne by the Company.

         1.8 Underwriting Requirements; Cut-backs.

                  (a) In connection with any offering involving an underwriting
         of shares of the Company's capital stock, the Company shall not be
         required to include any Holders' Registrable Securities in such
         underwriting unless they accept the terms of the underwriting as agreed
         upon between the Company and the underwriters selected by it (or by
         other persons entitled to select the underwriters), and then only in

                                      A-4
<PAGE>   5

         such quantity as the underwriters determine in their sole discretion
         will not materially jeopardize or in any way reduce the success of the
         offering by the Company.

                  (b) The Company has previously granted "piggyback"
         registration rights to certain of its security holders (the "Other
         Holders"). Notwithstanding any thing in this Section 1 to the contrary,
         in the event of any request for registration hereunder, the Company
         shall provide each Other Holder the notice required with respect to
         their registration rights and will allow such Other Holders to
         participate in any such registration to the extent of such registration
         rights; it being acknowledged and agreed that if the total amount of
         securities, including Registrable Securities, requested by security
         holders to be included in such offering exceeds the amount of
         securities that the underwriters determine in their sole discretion is
         compatible with the success of the offering (excluding any securities
         to be offered by the Company), then the Company shall be required to
         include in the offering only that number of such securities, including
         Registrable Securities, which the underwriters determine in their sole
         discretion will not jeopardize the success of the offering (the
         securities so included to be apportioned pro rata among the selling
         security holders (including Holders) according to the total amount of
         securities entitled to be included therein owned by each selling
         shareholder (including Holders) or in such other proportions as shall
         mutually be agreed to by such selling shareholders (including
         Holders)).

         1.9 Delay of Registration. No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1.

         1.10 Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 1:

                  (a) To the extent permitted by law, the Company will indemnify
         and hold harmless each Holder, any underwriter (as defined in the Act)
         for such Holder and each person, if any, who controls such Holder or
         underwriter within the meaning of the Act or the 1934 Act against any
         losses, claims, damages, or liabilities, joint or several) to which
         they may become subject under the Act, the 1934 Act or other federal or
         state law, insofar as such losses, claims, damages, or liabilities (or
         actions in respect thereof) arise out of or are based upon any of the
         following statements, omissions or violations (collectively a
         "Violation"): (i) any untrue statement or alleged untrue statement of a
         material fact contained in such registration statement, including any
         preliminary prospectus or final prospectus contained therein or any
         amendments or supplements thereto, (ii) 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, or
         (iii) any violation or alleged violation by the Company of the Act, the
         1934 Act, any state securities law or any rule or regulation
         promulgated under the 1934 Act or any state securities law; and,
         subject to subsection 1.10(c) below, the Company will pay to each such
         Holder, underwriter or controlling person, as incurred, any legal or
         other expenses reasonably incurred by them in connection with
         investigating or defending any such loss, claim, damage, liability, or
         action; provided, however, that the indemnity agreement contained in
         this subsection 1.10(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 reasonably withheld), nor shall the Company be
         liable 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 a Violation
         which occurs in reliance upon and in conformity with written
         information furnished expressly for use in connection with such
         registration by any such Holder, underwriter or controlling person.

                  (b) To the extent permitted by law, each selling Holder will
         indemnify and hold harmless the Company, each of its directors, each of
         its officers who has signed the registration statement, each person, if
         any, who controls the Company within the meaning of the Act, any
         underwriter, any other Holder selling securities in such registration
         statement and any controlling person of any such underwriter or other
         Holder, and any agent of the Company, against any losses, claims,
         damages, or liabilities joint or several) to which any of the foregoing
         persons may become subject, under the Act, the 1934 Act or other
         federal or state law, insofar as such losses, claims, damages, or
         liabilities (or actions in respect thereto) arise out of or are based
         upon any Violation, in each case to the extent (and only to the extent)
         that such Violation occurs in reliance upon and in conformity with
         written information furnished by such Holder expressly for use in
         connection

                                      A-5
<PAGE>   6

         with such registration; and each such Holder will pay, as incurred, any
         legal or other expenses reasonably incurred by any person intended to
         be indemnified pursuant to this subsection 1.10(b), in connection with
         investigating or defending any such loss, claim, damage, liability, or
         action; provided, however, that the indemnity agreement contained in
         this subsection 1.10(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 the Holder, which consent shall not
         be reasonably withheld; provided, that, in no event shall any indemnity
         under this subsection 1.10(b) exceed the gross proceeds from the
         offering received by such Holder.

                  (c) Promptly after receipt by an indemnified party under this
         Section 1.10 of notice of the commencement of any action (including any
         governmental action), such indemnified party will, if a claim in
         respect thereof is to be made against any indemnifying party under this
         Section 1.10, deliver to the indemnifying party a written notice of the
         commencement thereof and the indemnifying party shall have the right to
         participate in, and, to the extent the indemnifying party so desires,
         jointly with any other indemnifying party receiving similar notice, to
         assume the defense thereof with counsel reasonably satisfactory to the
         parties; provided, however, that an indemnified party (together with
         all other indemnified party which may be represented without conflict
         by one counsel) shall have the right to retain one separate counsel,
         with the fees and expenses to be paid by the indemnifying party, if
         representation of such indemnified party by the counsel retained by the
         indemnifying party would be inappropriate due to actual or potential
         differing interests between such indemnified party and any other party
         represented by such counsel in such proceeding; otherwise, the
         indemnified party shall be responsible for the fees and expenses of its
         counsel. The failure to deliver written notice to the indemnifying
         party within a reasonable time of the commencement of any such action,
         if prejudicial to its ability to defend such action, shall relieve such
         indemnifying party of any liability to the indemnified party under this
         Section 1.10.

                  (d) Except as provided in the last sentence of subsection
         1.10(c) above, if the indemnification provided for in this Section 1.10
         is held by a court of competent jurisdiction to be unavailable to an
         indemnified party with respect to any loss, liability, claim, damage,
         or expense referred to therein, then the indemnifying party, in lieu of
         indemnifying such indemnified party hereunder, shall contribute to the
         amount paid or payable by such indemnified party as a result of such
         loss, liability, claim, damage, or expense in such proportion as is
         appropriate to reflect the relative fault of the indemnifying party on
         the one hand and of the indemnified party on the other in connection
         with the statements or omissions that resulted in such loss, liability,
         claim, damage, or expense as well as any other relevant equitable
         considerations. The relative fault of the indemnifying party and of the
         indemnified party shall be determined by reference to, among other
         things, whether the untrue or alleged untrue statement of a material
         fact or the omission to state a material fact relates to information
         supplied by the indemnifying party or by the indemnified party.

                  (e) Notwithstanding the foregoing, to the extent that the
         provisions on indemnification and contribution contained in the
         underwriting agreement entered into in connection with the underwritten
         public offering are in conflict with the foregoing provisions, the
         provisions in the underwriting agreement shall control.

                  (f) The obligations of the Company and Holders under this
         Section 1.10 shall survive the completion of any offering of
         Registrable Securities pursuant to a registration statement under this
         Section 1.

         1.11 Assignment of Registration Rights. The registration rights of the
Holders under this Section 1 may be assigned (but only with all related
obligations) by a Holder to a transferee or assignee of such securities who
purchases from such Holder at least 10,000 shares of Registrable Securities
(subject to appropriate adjustment for stock splits, stock dividends,
combinations and other recapitalizations), provided: (a) the Company is promptly
after such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
document, including without limitation the provisions of Section 1.12 below; and
(c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Act.

                                      A-6
<PAGE>   7

         1.12 Lock-up Agreement. Each Holder hereby agrees that if requested by
the Company or the underwriters in any underwritten offering, such Holder shall
not, for the period of 180 days after the effective date of an underwritten
public offering of shares of Common Stock, without the prior written approval of
the Company or such underwriters (as the case may be), directly or indirectly,
sell, offer to sell, contract to sell (including without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of any
shares of Common Stock legally or beneficially owned by such Holder; provided,
however, in the event of an initial public offering of Common Stock, no request
shall be necessary, with the consent of such Holder to the above provisions in
this Section 1.12 being hereby granted and accepted, provided that if the
managing underwriter in such initial public offering requests that Holder
execute and deliver a lock-up letter, Holder agrees to do so, which lock-up
letter shall be in such managing underwriter's customary form. In order to
enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

         1.13 Termination of Registration Rights. Notwithstanding anything in
this Section 1 to the contrary, no Holder shall be entitled to exercise any
right provided for in this Section 1: (i) at any time more than four (4) years
following the date after the Company becomes a Public Company or (ii) at such
time as such Holder is able to sell all of such Holder's Registrable Securities
in a single three-month period in compliance with Rule 144.

         1.14 Amendments and Waivers. Any term or provision of the registration
rights stated in this Section 1 may be amended and the observance of any term of
such rights may be waived (either generally or in a particular instance and
either retroactively or prospectively), only with the written consent of the
Company and the holders of at least a majority of the Registrable Securities
then outstanding. Any amendment or waiver effected in accordance with this
Section 1.14 shall be binding upon each holder of any Registrable Securities
then outstanding, each future holder of any Registrable Securities, and the
Company.
