$6.00 per share. A copy of the Certificate of the Designations, Preferences,
Rights and Limitations of Series C Stock is attached hereto as Exhibit A. For
each share of Series C Stock purchased, you will receive, at no additional cost,
a warrant to purchase two (2) shares of the common stock, par value $ .01 per
share, of the Company (the "Common Stock"), the form of which is attached hereto
as Exhibit B (the "Warrant"). The Series C Stock and Warrant are sometimes
collectively referred to herein as the "Securities". The minimum subscription
amount is $25,000 per investor, unless agreed to by the Company. The Company may
pay commissions to brokers, if any, involved in this offering of Securities.

     2.1 The Securities. Subject to all of the terms and conditions of this
Agreement, the Company will issue and sell to you (sometimes referred to as
"Holder") the number of shares of Series C Stock shown on the signature page
hereof (in which event you will also be deemed to have purchased the Warrant for
the applicable number of shares of Common Stock as provided above for no
additional consideration) and you will purchase the same from the Company;
provided that all other terms and conditions set forth in this Purchase
Agreement are satisfied.

     2.2 Closing. The purchase by and sale and delivery to you of the Securities
(the "Closing") shall take place at the executive offices of the Company as set
forth above at such date and time as determined by the Company (such date being

Stock to be issued to you which was accepted by the Company; (ii) a Warrant on
the terms provided for in Section 1 above; and (iii) such other items as are
required to be delivered to it pursuant to this Purchase Agreement. The
Securities are being offered by the Company subject to the right of the Company
to reject, at its discretion, any subscription, in whole or in part, for any
reason, and to accept subscriptions notwithstanding the order in which they are
received. Any portion of a subscription not accepted by the Company shall be

     4.1 Authority. You have full power and authority to enter into this
Agreement and it constitutes your legal, valid and binding obligation,
enforceable in accordance with its terms.

     4.2 Purchase For Own Account. You are acquiring the Securities for your own
account, for investment purposes and not for resale or with a view to any
distribution, or in connection with any distribution thereof you are able to (i)
bear the economic risk of your investment in the Securities, (ii) hold the
Securities for an indefinite period of time, and (iii) afford a complete loss of
your investment.

     4.3 Investment Experience. You have the requisite knowledge and experience
in financial and business matters, including investments of this type, to be
capable of evaluating the merits and risks of an investment in the Securities
and of making an informed investment decision with respect thereto.

     4.4 Receipt Of Information. You have received from the Company all of the
information concerning the Company which you consider to be material in making
your investment decision, which information has been requested by you if not
already furnished by the Company. You have had full access to the books and
records of the Company and to its officers, directors and accountants for the

jurisdiction, that they may not be resold or transferred without compliance with
the registration or qualification provisions of the Act or applicable federal
and state securities laws of any state or other jurisdiction or an opinion of
counsel acceptable to the Company that an exemption from such registration and
qualification requirements is available.

Company of the proposed disposition and shall have furnished the Company with a
statement of the circumstances surrounding the proposed disposition and you have
furnished the Company with an opinion of counsel, reasonably satisfactory to the
Company, that such disposition will not require registration of such securities
under the Act and applicable securities laws of any state or other jurisdiction.

     4.7 Illiquid Investments. Your overall commitment to investments which are
not readily marketable is not disproportionate to your net worth and your
investment in the Securities will not cause such overall commitment to become
excessive. You have adequate means of providing for your current needs and
personal contingencies.

defined in Section 501(a) of Regulation D promulgated under the Act ("Regulation

     sale to the public under the Act. Upon receipt of such written request, the
     Company will promptly notify in writing all other Holders of Registerable
     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 Registerable 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 Registerable 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
     Registerable 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 Registerable 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 Registerable 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
     Registerable 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 Registerable 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 Registerable Securities),
     then the holders of Registerable 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 Registerable 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 Registerable Securities, the Company will promptly notify in
     writing all other Holders of Registerable 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
     Registerable 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 Registerable 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'
     Registerable 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)

                                      A-2

<PAGE>   11

     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
Registerable 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 Registerable 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 Registerable 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 Registerable 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 Registerable 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 Registerable Securities owned by them.

          (d) Use its best efforts to register or qualify all Registerable
     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 Registerable 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 Registerable 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 its is necessary, in the

                                      A-3
<PAGE>   12

     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
     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 Registerable 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 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) Notify each Holder of Registerable 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 Registerable 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 Registerable
     Securities registered pursuant hereunder and a CUSIP number for all such
     Registerable 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 Registerable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registerable
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 Registerable
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' Registerable 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.

                                      A-4

<PAGE>   13

          (b) The Company has previously granted "piggyback" registration rights
     to certain of its securityholders (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 Registerable 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 Registerable
     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 Registerable 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, 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.

                                      A-5
<PAGE>   14

          (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 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 Registerable 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

                                      A-6
<PAGE>   15

purchases from such Holder at least 10,000 shares of Registerable 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
piggyback 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. 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.

     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 underlying the Warrants 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 Registerable 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 Registerable 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 a majority of the Registerable Securities then
outstanding. Any amendment or waiver effected in accordance with this Section
1.14 shall be binding upon each holder of any Registerable Securities then
outstanding, each future holder of any Registerable Securities, and the Company.

                           (b) Subject to the terms and conditions of this
Agreement, each Purchaser agrees to purchase at the Closing (as defined below)
and the Company agrees to sell and issue to each Purchaser at the Closing that
number of shares of Series C Preferred Stock set forth opposite each such
Purchaser's name on Exhibit A attached hereto at a purchase price of $6.00 per
share; provided, however, that to the extent any shares of Series C Preferred
Stock are sold by the Company at a price less than $6.00 per share, each
Purchaser who purchased shares of Series C Preferred Stock at a price higher
than the lowest issuance price will receive, and the Company agrees to issue,
additional shares of Series C Preferred Stock so that such Purchaser receives
the benefit of such lower issuance price by issuing additional shares of Series
C Preferred Stock in an amount equal to the remainder of (i) the aggregate
amount of such Purchaser's original investment divided by such lower issuance
price minus (ii) the aggregate number of shares of Series C Preferred Stock then
issued to the Purchaser (subject to adjustment for all stock splits, stock
dividends, combinations, recapitalization and the like), and Exhibit A will be
amended accordingly (without any action on the part of the Purchasers). The
shares of Series C Preferred Stock issued to the Purchaser pursuant to this
Agreement shall be hereinafter referred to as the "Stock". The Stock and the
Common Stock issuable upon conversion of the Stock shall be hereinafter referred
to as the "Securities."

                  1.2 CLOSING; DELIVERY.

                           (a) The purchase and sale of the Stock shall take

                  2.7 LITIGATION. There is no action, suit, proceeding or
investigation pending or, to the best knowledge of the Company, currently
threatened against the Company or any of its subsidiaries that questions the
validity of the Agreements or the right of the Company to enter into them, or to
consummate the transactions contemplated hereby or thereby, or that might
result, either individually or in the aggregate, in any material adverse changes
in the assets, condition or affairs of the Company, financially or otherwise, or
any change in the current equity ownership of the Company, nor is the Company
aware that there is any basis for the foregoing. The foregoing includes, without
limitation, actions pending or to the best knowledge of the Company threatened
in writing involving the prior employment of any of the Company's employees,
their use in connection with the Company's business of any information or
techniques allegedly proprietary to any of their former employers. Neither the
Company nor any of its subsidiaries is a party or subject to the provisions of

SERIES C PREFERRED STOCK PURCHASE AGREEMENT - PAGE 4
<PAGE>   6

licenses, information and other proprietary rights and processes of any other
person or entity other than such licenses or agreements arising from the
purchase of "off the shelf' or standard commercial products. The Company has not
received any communications alleging that the Company has violated or, by
conducting its business, would violate any of the patents, trademarks, service
marks, trade names, copyrights, trade secrets or other proprietary rights or
processes of any other person or entity. The Company, to the best of its
knowledge, is not aware that any of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee's best
efforts to promote the interest of the Company or that would conflict with the
Company's business. To the best knowledge of the Company, neither the execution
or delivery of this Agreement, nor the carrying on of the Company's business by
the employees of the Company, nor the conduct of the Company's business as
proposed, will conflict with or result in a breach of the terms, conditions, or
provisions of, or constitute a default under, any contract, covenant or
instrument under which any such employee is now obligated. The Company does not
believe it is or will be necessary to use any inventions of any of its employees
(or persons it currently intends to hire) made prior to their employment by the
Company.

                           (a) The Company is not in violation or default of any
provisions of (i) its Certificate of Incorporation or Bylaws (as such documents
are in force and effect as of the Closing Date) or (ii) any instrument,
judgment, order, writ, decree or contract to which it is a party or by which it
is bound, the violation of, or default, which would have a material adverse
effect on the Company, or, to the best knowledge of the Company, of any
provision of federal or state statute, rule or regulation applicable to the
Company. The execution, delivery and performance of the Agreements and the
consummation of the transactions contemplated hereby or thereby will not result
in any such violation or be in conflict with or constitute, with or without the
passage of time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an event which results
in the creation of any lien, charge or encumbrance upon any assets of the
Company.

                           (b) The Company has avoided every condition, and has
not performed any act, the occurrence of which would result in the Company's
loss of any right granted under any license, distribution agreement or other
agreement.

                  2.10 AGREEMENTS; ACTION.

                           (a) There are no agreements, understandings or
proposed transactions between the Company and any of its officers, directors,

contracts or proposed transactions to which the Company or any of its
subsidiaries is a party or by which it is bound that involve (i) obligations
(contingent or otherwise) of, or payments to, the Company or any of its
subsidiaries in excess of, $100,000, (ii) the license of any patent, copyright,
trade secret or other proprietary right to or from the Company or any of its
subsidiaries, (iii) the grant of rights (excluding contract manufacturing rights
and relationships) to manufacture, produce, assemble, license, market, or sell
its products to any other person or affect the Company's exclusive right to
develop, manufacture, assemble, distribute, market or sell its products; or (iv)
indemnification by the Company with respect to infringement of proprietary
rights (other than indemnification obligations arising from purchase or sale
agreements entered into in the ordinary course of business).

                           (c) Neither the Company nor any of its subsidiaries
has (i) declared or paid any dividends, or authorized or made any distribution
upon or with respect to any class or series of its capital stock, (ii) incurred
any indebtedness for money borrowed or incurred any other liabilities
individually in excess of $25,000 or in excess of $100,000 in the aggregate,

                  2.11 DISCLOSURE. The Company has fully provided the Purchasers
with all the information that the Purchasers have requested for deciding whether

necessary to enable the Purchasers to make such a decision, including certain of
the Company's projections describing its proposed business contained in the
Mobility Electronics Company and Business Summary dated March 5, 1999 (the
"Company Summary"). No representation or warranty of the Company contained in
this Agreement and the exhibits attached hereto, any certificate furnished or to
be furnished to Purchasers at the Closing, or the Company Summary (when read
together) contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained herein or
therein not misleading in light of the circumstances under which they were made.
To the extent the Company Summary was prepared by management of the Company, the
Company Summary and the financial and other projections contained in the Company
Summary and other written information provided to the Purchaser were prepared in
good faith (with the exception of information prepared by third party sources
and identified as such in the Company Summary or other written information and
to which the Company makes no representation except that it has no basis to
believe such sections are inaccurate); however, the Company does not warrant
that it will achieve such projections.

                  2.12 NO CONFLICT OF INTEREST. The Company is not indebted,
directly or indirectly, to any of its officers or directors or to their
respective spouses or children, in any amount whatsoever other than in
connection with expenses or advances of expenses incurred in the ordinary course
of business or relocation expenses of employees which amount does not in the
aggregate exceed

<PAGE>   8

$50,000. None of the Company's officers or directors, or any members of their
immediate families, are, directly or indirectly, indebted to the Company (other
than in connection with purchases of the Company's stock) or to the best
knowledge of the Company have any direct or indirect ownership interest in any
firm or corporation with which the Company is affiliated or with which the
Company has a business relationship, or any firm or corporation which competes
with the Company except that officers, directors and/or stockholders of the
Company may own stock in (but not exceeding two percent of the outstanding
capital stock of) any publicly traded company that may compete with the Company.
None of the Company's officers or directors or any members of their immediate
families are, directly or indirectly, interested in any material contract with
the Company. The Company is not a guarantor or indemnitor of any indebtedness of
any other person, firm or corporation.

                  2.13 RIGHTS OF REGISTRATION AND VOTING RIGHTS. Except as
contemplated in the Investors' Rights Agreement, the Company has not granted or
agreed to grant any registration rights, including piggyback rights, to any
person or entity. To the best knowledge of the Company, no stockholder of the
Company has entered into any agreements with respect to the voting of capital
shares of the Company.

                  2.14 TITLE TO PROPERTY AND ASSETS. The Company owns its
property and assets free and clear of all mortgages, liens, loans and
encumbrances, except such encumbrances and liens which arise in the ordinary
course of business and do not materially impair the Company's ownership or use
of such property or assets. With respect to the property and assets it leases,
the Company is in compliance with such leases and, to its knowledge, holds a
valid leasehold interest free of any liens, claims or encumbrances. The Company
is in compliance with all material terms of each material lease to which it is a
party or otherwise bound.

                  2.15 FINANCIAL STATEMENTS. The Company has made available to
each Purchaser the financial statements set forth in the Company Summary
(collectively, the "Financial Statements"). The Financial Statements have been
prepared in accordance with generally accepted accounting principles applied on
a consistent basis throughout the periods indicated, except that the unaudited
Financial Statements may not contain all footnotes required by generally
accepted accounting principles. The Financial Statements fairly present the
financial condition and operating results of the Company as of the dates, and

adjustments. Except as set forth in the Financial Statements, the Company has no
material liabilities, contingent or otherwise, other than (i) liabilities
incurred in the ordinary course of business subsequent to January 1, 1999 and
(ii) obligations under contracts and commitments incurred in the ordinary course

respect to its business, properties and operations for such period. The Company
has withheld or collected from each payment made to each of its employees, the
amount of all taxes (including, but not limited to, federal income taxes,
federal Insurance Contribution Act taxes and Federal Unemployment Tax Act taxes)

proper tax receiving officers or authorized depositories.

                  2.19 INSURANCE. The Company has in full force and effect fire

Company pending, or to the best knowledge of the Company threatened, which could
have a material adverse effect on the assets, properties, financial condition,

labor organization activity involving its employees. The Company is not aware
that any officer or key employee, or that any group of key employees, intends to
terminate their employment with the Company, nor does the Company have a present
intention to terminate the employment of any of the foregoing. The employment of
each officer and employee of the Company is terminable at the will of the
Company. The Company has complied in all material respects with all applicable

applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance, and any other laws of general application affecting enforcement of
creditors' rights generally, and as limited by laws relating to the availability

<PAGE>   13

                  3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made
with the Purchaser in reliance upon the Purchaser's representation to the
Company, which by the Purchaser's execution of this Agreement the Purchaser
hereby confirms, that the Securities to be acquired by the Purchaser will be
acquired for investment for the Purchaser's own account, not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof,
and that the Purchaser has no present intention of selling, granting any
participation in, or otherwise distributing the same. By executing this
Agreement, the Purchaser further represents that the Purchaser does not
presently have any contract, undertaking, agreement or arrangement with any
person to sell, transfer or grant participation to such person or to any third
person, with respect to any of the Securities. The Purchaser has not been formed
for the specific purpose of acquiring the Securities.

                  3.3 DISCLOSURE OF INFORMATION. The Purchaser has had an
opportunity to discuss the Company's business, management, financial affairs and
the terms and conditions of the offering of the Stock with the Company's
management and has had an opportunity to review the Company's facilities. The
Purchaser understands that such discussions, as well as the Company Summary and
any other written information delivered by the Company to the Purchaser, were
intended to describe the aspects of the Company's business which it believes to
be material.

                  3.4 RESTRICTED SECURITIES. The Purchaser understands that the
Securities have not been, and will not be, registered under the Securities Act,
by reason of a specific exemption from the registration provisions of the
Securities Act which depends upon, among other things, the bona fide nature of
the investment intent and the accuracy of the Purchaser's representations as
expressed herein. The Purchaser understands that the Securities are "restricted
securities" under applicable U.S. federal and state securities laws and that,
pursuant to these laws, the Purchaser must hold the Securities indefinitely
unless they are registered with the Securities and Exchange Commission and
qualified by state authorities, or an exemption from such registration and
qualification requirements is available. The Purchaser acknowledges that the
Company has no obligation to register or qualify the Securities for resale
except as set forth in the Investors' Rights Agreement. The Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Securities,
and on requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

                  3.5 NO PUBLIC MARKET. The Purchaser understands that no public
market now exists for any of the securities issued by the Company, and that the
Company has made no assurances that a public market will ever exist for the
Securities.

                  3.6 LEGENDS. The Purchaser understands that the Securities,
and any securities issued in respect of or exchange for the Securities, may bear
one or all of the following legends (or substantially similar legends):
