("Other Purchasers") of up to $5 million of shares of Series C Preferred Stock,
par value $0.01 per share, of the Company (the "Series C Stock"), at a price of
$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

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. PURCHASE AND SALE

     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
hereinafter called the "Closing Date"). At the Closing, the Company shall

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
promptly returned to you, without interest or deduction.

     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
purpose of obtaining and verifying such information and you have had an
opportunity to ask questions and receive answers from the officers of the

Act of 1933, as amended (the "Act"), or the securities laws of any other
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.

     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>

     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>

     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>

          (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>

          (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>

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.
