This Common Stock Purchase Agreement (this "AGREEMENT") is made as of April 7,
2004 by and between Distributed Delivery Networks Corporation, a Delaware

Company is presently qualified to do business as a foreign corporation in


                                       1


California and there is no other jurisdiction in which the failure to be so
qualified would have a material adverse effect on the business or financial
condition of the Company.

Agreement in substantially the form attached hereto as EXHIBIT C (the "INVESTOR

hereunder, and to carry out and perform its obligations under the terms of the
Investment Agreements.

         3.3 SUBSIDIARIES. The Company has no subsidiaries or affiliated
companies and does not otherwise own or control, directly or indirectly, any
equity interest in any corporation, association or business entity.

         3.4 CAPITALIZATION. The authorized capital stock of the Company will,

substantially the form attached hereto as EXHIBIT A (the "RESTATED
CERTIFICATE"), consist of 2,550,000 shares of Common Stock Upon the filing of
the Restated Certificate and immediately prior to the Closing, no shares of
Common Stock will be outstanding. There are no options, warrants or other rights

stock.

         3.5 AUTHORIZATION. All corporate action on the part of the Company, its
directors and stockholders necessary for the authorization, execution, delivery
and performance of the Investment Agreements by the Company, the authorization,
sale, issuance and delivery of the Shares and the performance of the Company's
obligations under the Investment Agreements has been taken or will be taken
prior to the Closing. The Investment Agreements, when executed and delivered by
the Company, shall constitute valid and binding obligations of the Company,
enforceable in accordance with their terms, subject to laws of general
application relating to bankruptcy, insolvency and the relief of debtors and
rules of law governing specific performance, injunctive relief or other
equitable remedies; PROVIDED, HOWEVER, that the Company makes no representation
as to the enforceability of the indemnification provisions contained in the
Investor Rights Agreement. The Shares, when issued in compliance with the
provisions of this Agreement, will be validly issued, fully paid and


                                       2


nonassessable, and the Shares will be free of any liens or encumbrances
(assuming the Purchaser takes the Shares with no notice thereof) other than any
liens or encumbrances created by or imposed upon the holder; PROVIDED, HOWEVER,
that the Shares may be subject to restrictions on transfer under state or
federal securities laws and restrictions set forth in the Investor Rights
Agreement.

         3.6 PROPRIETARY RIGHTS. To the knowledge of the Company, none of its
employees or consultants 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 his or her best efforts to promote the interests of
the Company or that would conflict with the Company's business as currently
conducted. Neither the execution and delivery of the Investment Agreements, nor
the carrying on of the Company's business by the employees and consultants of
the Company, nor the conduct of the Company's business as currently conducted,
will, to the Company's knowledge, 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 of such employees or consultants is now
obligated.

         3.7 GOVERNMENTAL CONSENT, ETC. No consent, approval, order or
authorization of or registration, qualification, designation, declaration or
filing with any governmental authority on the part of the Company is required in
connection with the valid execution and delivery of the Investment Agreements,
or the offer, sale or issuance of the Shares, or the consummation of any other
transaction contemplated hereby, except (a) the filing of the Restated
Certificate in the office of the Delaware Secretary of State prior to the
Closing and (b) the qualification (or taking of such action as may be necessary
to secure an exemption from qualification, if available) of the offer and sale
of the Shares under applicable Blue Sky laws, which filings and qualifications,
if required, will be accomplished in a timely manner.

         3.8 OFFERING. Subject to the accuracy of the Purchaser's
representations in Section 4 hereof, the offer, sale and issuance of the Shares
constitute transactions exempt from the registration requirements of Section 5
of the Securities Act of 1933, as amended (the "SECURITIES ACT"), and the
qualification or registration requirements of the California Corporate
Securities Law of 1968, as amended, or other applicable Blue Sky laws. Neither
the Company nor any authorized agent acting on its behalf will knowingly take
any action hereafter that would cause the loss of such exemptions.

         3.9 PERMITS. The Company has all franchises, permits, licenses, and any
similar authority necessary for the conduct of its business as now being
conducted, the lack of which could materially and adversely affect the business
or financial condition of the Company, and the Company believes it can obtain,
without undue burden or expense, any similar authority for the conduct of its
business as planned to be conducted. To its knowledge, the Company is not in
default in any material respect under any of such franchises, permits, licenses,
or other similar authority.

         3.10 COMPLIANCE WITH LAWS. The Company is not in violation of or in
default under any provision of its Restated Certificate or Bylaws or in any
material respect of any instrument, judgment, order, writ, decree or contract to
which it is a party or by which it is bound, or, to the Company's knowledge, of
any provision of any federal or state statute, rule or regulation applicable to
the Company. The execution, delivery and performance of this Agreement and all


                                       3


other agreements contemplated hereby to which the Company is a party and the
consummation of the transactions contemplated hereby 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 material default under any such provision,
instrument, judgment, order, writ, decree or contract or an event that results
in the creation of any lien, charge or encumbrance upon any assets of the
Company or the suspension, revocation, impairment, forfeiture or non-renewal of
any material permit, license, authorization or approval applicable to the
Company, its business or operations or any of its assets or properties.

         3.11 LITIGATION, ETC. There is no action, suit, proceeding or
investigation pending or, to the Company's knowledge, currently threatened
against the Company that questions the validity of this Agreement, or the
Investment Agreements or the right of the Company to enter into any of such
agreements, or to consummate the transactions contemplated hereby or thereby, or
which would likely result, either individually or in the aggregate, in any
material adverse change in the business or financial condition of the Company,
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 threatened in writing involving the prior
employment of any of the Company's employees or consultants, their use in
connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers or clients, as the case
may be, or their obligations under any agreements with prior employers or
clients, as the case may be. The Company is not a party or subject to the
provisions of any order, writ, injunction, judgment or decree of any court or
government agency or instrumentality. There is no action, suit, proceeding or
investigation by the Company currently pending or that the Company intends to
initiate.

         3.12 EMPLOYEES. The Company has no collective bargaining agreements
with any of its employees. There is no labor union organizing activity pending
or, to the Company's knowledge, threatened with respect to the Company. The
Company is not aware that any officer or key employee intends to terminate his
or her employment with the Company, nor does the Company have a present
intention to terminate the employment of any officer or key employee.

         3.13 PROPRIETARY INFORMATION AGREEMENTS. Each employee and officer of
the Company has executed, or will execute in connection with the Closing, a
Proprietary Information and Inventions Agreement in substantially the form or on
substantially the same terms provided to counsel to the Purchaser. The Company
is not aware that any of its employees, officers or consultants are in violation
thereof, and the Company will use commercially reasonable efforts to prevent any
such violation.

         3.14 DISCLOSURE. Neither this Agreement (including all the exhibits and
schedules hereto), nor any other statements or certificates made or delivered in
connection herewith contains any untrue statement of a material fact or omits to
state a material fact necessary to make the statements herein or therein not
misleading in light of the circumstances under which they were made.

         3.15 BROKERS OR FINDERS. The Purchaser has not and will not incur,
directly or indirectly, as a result of any action taken by the Company, any
liability for brokerage or finders' fees or agents' commissions or any similar
charges in connection with this Agreement or the transactions contemplated
hereby.


                                       4


          SECTION 4 - REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

The Purchaser hereby represents and warrants to the Company as follows:

         4.1 ACCREDITED INVESTOR. The Purchaser is an "ACCREDITED INVESTOR"
within the meaning of Rule 501(a) under the Securities Act, and the Common Stock
to be acquired by it pursuant to this Agreement is being acquired for its own
account, not as a nominee or agent, and not with a view to, or for resale in
connection with, any distributions thereof. The Purchaser has such knowledge and
experience in financial and business matters so as to be capable of evaluating
the merits and risks of its investment in the Common Stock, and it is capable of
bearing the economic risks of such investment.

         4.2 BLUE SKY. The Purchaser understands that the issuance of the Shares
has 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, the
availability of which depends upon, among other things, the bona fide nature of
the Purchaser's investment intent and the accuracy of the Purchaser's
representations as expressed herein.

         4.3 RULE 144. The Purchaser acknowledges that the Shares must be held
indefinitely unless subsequently registered under the Securities Act or unless
an exemption from such registration is available. It is aware of the provisions
of Rule 144 promulgated under the Securities Act which permit limited resale of
shares purchased in a private placement subject to the satisfaction of certain
conditions, including, among other things, the existence of a public market for
the shares, the availability of certain current public information about the
Company, the resale occurring not less than one year after a party has purchased
and paid for the security to be sold, the sale being effected through a
"BROKER'S TRANSACTION" or in a transaction directly with a "MARKET maker," and
the number of shares being sold during any three-month period not exceeding
specified limitations.

         4.4 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 Company's
securities.

         4.5 RESTRICTIONS ON TRANSFER; RESTRICTIVE LEGENDS. The Purchaser
understands that the transfer of the Shares is restricted by applicable state
and federal securities laws and by the provisions of the Investor Rights
Agreement, and that the certificates representing the Shares will be imprinted
with legends restricting transfer except in compliance therewith.

         4.6 ACCESS TO DATA. The Purchaser has had an opportunity to discuss the
Company's business, management and financial affairs with the Company's
management. It has also had an opportunity to ask questions of officers of the
Company. It understands that such discussions, as well as any written
information issued by the Company, were intended to describe certain aspects of
the Company's business and prospects but were not a thorough or exhaustive
description. The foregoing, however, does not limit or modify the
representations and warranties of the Company in Section 3 of this Agreement, or
the right of the Purchaser to rely thereon.


                                       5


         4.7 AUTHORIZATION. All action on the part of the Purchaser's Board of
Directors and stockholders, as applicable, necessary for the authorization,
execution, delivery and performance by the Purchaser of the Investment
Agreements to which the Purchaser is a party, the purchase of and payment for
the Shares and the performance of all of the Purchaser's obligations under the
Investment Agreements has been taken or will be taken prior to the Closing. The
Investment Agreements to which the Purchaser is a party, when executed and
delivered by the Purchaser, shall constitute valid and binding obligations of
the Purchaser, enforceable in accordance with their terms, subject to laws of
general application relating to bankruptcy, insolvency and the relief of debtors
and rules of law governing specific performance, injunctive relief or other
equitable remedies; PROVIDED, HOWEVER, that the Purchaser makes no
representation as to the enforceability of the indemnification provisions
contained in the Investor Rights Agreement.

         4.8 BROKERS OR FINDERS. The Company has not and will not incur,
directly or indirectly, as a result of any action taken by the Purchaser, any
liability for brokerage or finders' fees or agents' commissions or any similar
charges in connection with this Agreement or the transactions contemplated
hereby.


               SECTION 5 - CONDITIONS TO CLOSING OF THE PURCHASER

The Purchaser's obligation to purchase the Shares is, unless waived in writing
by the Purchaser, subject to the fulfillment as of the Closing Date of the
following conditions:

         5.1 REPRESENTATIONS AND WARRANTIES CORRECT. The representations and

3.6  PROPRIETARY RIGHTS.

         William Holmes, the Company's President and Chief Executive Officer,
has a long history of creating intellectual property, including in the areas of
vending and automation, both as an individual and for other companies with which
he has worked. Mr. Holmes was previously employed by, a consultant to and/or
otherwise involved with the following companies: Pyxis, OmniCell and SupplyPro.
In connection with these relationships, Mr. Holmes entered into employment,
consulting, intellectual property and non-disclosure contracts with these
companies that provide for, among other things, the assignment of certain
intellectual property from Mr. Holmes to the companies, and prohibit the
disclosure of such intellectual property to any other person. Each of these
companies manufactures products that may be competitive with the Company's or
Purchaser's products or that may contain technology similar to the technology in
the Company's or Purchaser's products (or both), and Mr. Holmes was active in
creating such products and technology for these companies as well as for the
Company and Purchaser. Mr. Holmes's ongoing obligations (including
confidentiality obligations) under these various agreements with Pyxis,
OmniCell, and SupplyPro, and the intellectual property assignments contained in
such agreements, may prevent him from disclosing to the Company or Purchaser, or
using for the benefit of the Company or Purchaser, certain information or
intellectual property that would benefit the Company or Purchaser. Also, while
Mr. Holmes believes he has done nothing that would violate the terms of these
agreements, there is no asssurance that one or more of these companies will not
assert claims against Mr. Holmes, the Company or Purchaser which, even if
meritless, would detract from or interfere with Mr. Holmes's ability to promote
the interests of the Company.

         Mr. Holmes has signed a Non-Disclosure Agreement with Asteres (the
"ASTERES NDA") providing that, among other things, Mr. Holmes will keep any
proprietary information of Asteres confidential and not use such information for
any purpose. Prior to signing the Asteres NDA, Mr. Holmes had discussions with
Linda Pinney, the CEO of Asteres, wherein Ms. Pinney disclosed to Mr. Holmes
certain elements of the Asteres business plan and described the Asteres product.
Following the execution of the Asteres NDA, Mr. Holmes continued to advise
Asteres regarding its business plan. Later, after Asteres' vending machine was
installed in a pharmacy, Mr. Holmes visited the pharmacy, was shown the vending
machine and had discussions in the pharmacy about how it operated with a group
of Asteres engineers, employees and consultants. Mr. Holmes also introduced the
Purchaser to Asteres as a potential manufacturer of the Asteres vending machine.
Asteres is a potential competitor of the Company and Purchaser. Mr. Holmes's
ongoing obligations under the Asteres NDA may prevent him from disclosing to the
Company or Purchaser, or using for the benefit of the Company or Purchaser,
certain information or intellectual property that would benefit the Company or
Purchaser. Also, while Mr. Holmes believes he has done nothing that would
violate the terms of the Asteres NDA, there is no asssurance that Asteres will
not assert claims against Mr. Holmes, the Company or Purchaser which, even if
meritless, would detract from or interfere with Mr. Holmes's ability to promote
the interests of the Company.

         David Blackburn has also had similar extensive experience with the
foregoing and other companies in the markets in which the Company and the
Purchaser intend to operate, had extensive discussions with Asteres relative to
its products and proposed business, and has been provided a copy of Asteres'
official business plan.


                                      B-2


         Any of the companies with which Mr. Holmes or Mr. Blackburn has had
involvement, and SupplyPro and Asteres in particular, may claim that the
intellectual property developed by Purchaser, the Company, Mr. Holmes or Mr.
Blackburn was the confidential information of such other company. Said companies
may seek to assert that the Company, Purchaser, Mr. Holmes and/or Mr. Blackburn
has misappropriated their technology or otherwise breached one or more of the
foregoing consulting, intellectual property, employment or non-disclosure
agreements. In addition, such companies may seek to assert that the products or
technology being developed by Purchaser and the Company infringes their
intellectual property rights. The Company can provide no assurance to Purchaser
that any of the products or technology purported to be owned by, licensed to,
created or developed by the Company, Mr. Holmes or Mr. Blackburn, in any
capacity or at any time whatsoever, is free from such claims by such third
parties, or others. However, as noted above, Mr. Holmes believes he has done
nothing that would violate the terms of any of the foregoing agreements or
otherwise give rise to any liability to the Company or Purchaser as a result of
any such claims. Moreover, the foregoing agreements may limit Mr. Holmes's
ability to solicit employees, customers and contractors of the above companies.

form (in addition to any legends required by agreement or by applicable state
securities laws):

                  THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                  UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). SUCH
                  SECURITIES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR
                  HYPOTHECATED UNLESS REGISTERED UNDER THE ACT OR UNLESS IN THE
                  OPINION OF COUNSEL FOR THE COMPANY, SUCH SALE, TRANSFER,
                  ASSIGNMENT, PLEDGE OR HYPOTHECATION MAY BE MADE PURSUANT TO
                  RULE 144 OR REGISTRATION UNDER THE ACT IS OTHERWISE
                  UNNECESSARY.

                  THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
                  LOCKUP PERIOD OF UP TO 180 DAYS FOLLOWING THE EFFECTIVE DATE
                  OF A REGISTRATION STATEMENT OF THE COMPANY FILED UNDER THE
                  SECURITIES ACT OF 1933, AS AMENDED, AS SET FORTH IN AN
                  AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE
                  SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL
                  OFFICE OF THE ISSUER. SUCH LOCKUP PERIOD IS BINDING ON
                  TRANSFEREES OF THESE SHARES.

         Each Holder consents to the Company making a notation on its records
and giving stop transfer instructions to any transfer agent of its capital stock
in order to implement the restrictions on transfer established in this
Agreement.

         4. NOTICE OF PROPOSED TRANSFERS. The holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 4. Without in any way limiting the


                                      C-3


immediately preceding sentence, no sale, assignment, transfer or pledge of
Restricted Securities shall be made by any holder thereof to any person unless
such person shall first agree in writing to be bound by the restrictions of this
Agreement. Prior to any proposed sale, assignment, transfer or pledge of any
Restricted Securities, unless there is in effect a registration statement under
the Securities Act covering the proposed transfer, the holder thereof shall give
written notice to the Company of such holder's intention to effect such
transfer, sale, assignment or pledge. Each such notice shall describe the manner
and circumstances of the proposed transfer, sale, assignment or pledge in
reasonable detail, and, if reasonably requested by the Company in its sole
determination, the holder shall also provide, at such holder's expense, either
(i) a written opinion of legal counsel who shall be, and whose legal opinion
shall be, reasonably satisfactory to the Company addressed to the Company, to
the effect that the proposed transfer of the Restricted Securities may be
effected without registration under the Securities Act, or (ii) a "NO ACTION"
letter from the Commission to the effect that the transfer of such securities
without registration will not result in a recommendation by the staff of the
Commission that action be taken with respect thereto, whereupon the holder of
such Restricted Securities shall be entitled to transfer such Restricted
Securities in accordance with the terms of the notice delivered by the holder to
the Company; PROVIDED, HOWEVER, that the Company shall not request an opinion of
counsel or "NO ACTION" letter with respect to (i) a transfer not involving a
change in beneficial ownership, (ii) a transaction involving the distribution
without consideration of Restricted Securities by the holder to its constituent
partners or members in proportion to their ownership interests in the holder, or
(iii) a transaction involving the transfer without consideration of Restricted
Securities by an individual holder during such holder's lifetime by way of gift
or on death by will or intestacy. Each certificate evidencing the Restricted
Securities transferred as above provided shall bear, except if such transfer is
made pursuant to Rule 144, the appropriate restrictive legend set forth in
Section 3 above, except that such certificate shall not bear such restrictive
legend if in the opinion of counsel for such holder and counsel for the Company
such legend is not required in order to establish compliance with any provision
of the Securities Act.

         5. REGISTRATION.

                  5.1 REQUESTED REGISTRATION.

                           (a) REQUEST FOR REGISTRATION. In case the Company
shall receive from Initiating Holders a written request that the Company effect
any registration with respect to shares of Registrable Securities, the Company
will:

                                    (i) promptly give written notice of the
proposed registration to all other Holders; and

                                    (ii) as soon as practicable, use
commercially reasonable efforts to effect such registration as may be so
requested and as would permit or facilitate the sale and distribution of all or
such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request by delivering a written notice to such effect to
the Company within twenty (20) days after the date of such written notice from
the Company.

                  Notwithstanding the foregoing, the Company shall not be
obligated to take any action to effect or complete any such registration
pursuant to this Section 5.1:


                                      C-4


                                        (A) Prior to the date which is six (6)
months after the effective date of the Company's first registered public
offering of its Common Stock;

                                        (B) Unless the requested registration
would have an aggregate offering price of all Registrable Securities sought to
be registered by all Holders of at least $5,000,000 (Five Million U.S. Dollars);

                                        (C) Following the filing of, and for one
hundred eighty (180) days immediately following the effective date of, any
registration statement pertaining to securities of the Company (other than a
registration of securities in a Rule 145 transaction or with respect to an
employee benefit plan), provided that the Company is actively employing in good
faith commercially reasonable efforts to cause such registration statement to
become effective;

                                        (D) After the Company has effected three
(3) registrations pursuant to this Section 5.1;

                                        (E) If the Initiating Holders are able
to request a registration on Form S-3 pursuant to Section 5.3 hereof;

                                        (F) Within twelve (12) months after the
Company has effected such a registration pursuant to this Section 5.1, and such
registration has been declared or ordered effective; or

                                        (G) If the Company shall furnish to the
Initiating Holders a certificate signed by the President of the Company (i)
giving notice of its bona fide intention to effect the filing of a registration
statement with the Commission within the next sixty (60) days, or (ii) stating
that in the good faith judgment of the Board of Directors it would be seriously
detrimental to the Company or its stockholders for a registration statement to
be filed in the near future. In such case, the Company's obligation to use its
commercially reasonable efforts to register, qualify or comply under this
Section 5.1(a) shall be deferred one or more times for a period not to exceed
one hundred twenty (120) days from the receipt of the request to file such
registration by such Initiating Holders, PROVIDED, HOWEVER, that the Company may
not exercise this deferral right more than once per twelve (12) month period.

                                    Subject to the foregoing clauses (A) through
(G), the Company shall file a registration statement covering the Registrable
Securities so requested to be registered as soon as practicable after receipt of
the request or requests of the Initiating Holders.

                           (b) UNDERWRITING. If requested by the Initiating
Holders, a registration pursuant to Section 5.1 may be part of an underwritten
public offering with underwriters reasonably acceptable to the Initiating
Holders and the Company (including, without limitation, appropriate
qualification under applicable state securities laws and appropriate compliance
with applicable regulations issued under the Securities Act and any other
governmental requirements or regulations). In the event a registration pursuant
to Section 5.1 involves an underwriting, the Company shall advise the Holders as
part of the notice given pursuant to Section 5.1(a)(i) that the right of any
Holder to registration pursuant to Section 5.1 shall be conditioned upon such


                                      C-5


Holder's participation in the underwriting arrangements required by this Section
5.1(b), and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

                           The Company shall, together with all Holders
proposing to distribute their securities through such underwriting, enter into
an underwriting agreement in customary form with the managing underwriter
selected for such underwriting by a majority in interest of the Initiating
Holders, but subject to the Company's reasonable approval. Notwithstanding any
other provision of this Section 5.1, if the managing underwriter determines that
marketing factors require a limitation of the number of shares to be
underwritten, the managing underwriter may limit the Registrable Securities to
be included in such registration (i) in the case of the Company's initial public
offering, to zero, and (ii) in the case of any other offering, to an amount no
less than thirty percent (30%) of all shares to be included in such offering;
PROVIDED, however, that the number of shares of Registrable Securities to be
included in such underwriting shall not be reduced unless all other stockholder
securities are first entirely excluded from the underwriting. The Company shall
so advise all Holders requesting to be included in the registration and
underwriting, and the number of shares of Registrable Securities that may be
included in the registration and underwriting shall be allocated among all
Holders requesting to be included in the registration and underwriting in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities held by them at the time of filing the registration statement. To
facilitate the allocation of shares in accordance with the above provisions, the
Company or the underwriters may round the number of shares allocated to any
Holder to the nearest 100 shares. 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.

                  5.2 COMPANY REGISTRATION.

                           (a) NOTICE OF REGISTRATION. If at any time or from
time to time the Company shall determine to register any of its equity
securities, either for its own account or the account of a Holder or other
holders, other than (i) a registration relating solely to employee benefit
plans, (ii) a registration relating solely to a Rule 145 transaction, or (iii) a
registration in which the only equity security being registered is Common Stock
issuable upon conversion of convertible debt securities that are also being
registered, the Company will:

                                    (i) promptly give to each Holder written
notice thereof; and

                                    (ii) include in such registration (and any
related qualifications including compliance with Blue Sky laws), and in any
underwriting involved therein, all the Registrable Securities specified in a
written request or requests, made within twenty (20) days after the date of such
written notice from the Company, by any Holder.

                           (b) UNDERWRITING. If the registration of which the
Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise each Holder as a part of the written
notice given pursuant to Section 5.2(a)(i). In such event, the right of any
Holder to registration pursuant to Section 5.2 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of Registrable
Securities in the underwriting shall be limited to the extent provided herein.


                                      C-6


                  All Holders proposing to distribute their securities through
such underwriting shall (together with the Company and the other Holders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the managing underwriter selected
for such underwriting by the Company. Notwithstanding any other provision of
this Section 5.2, if the managing underwriter determines that marketing factors
require a limitation of the number of shares to be underwritten, the managing
underwriter may limit the Registrable Securities to be included in such
registration (i) in the case of the Company's initial public offering, to zero,
and (ii) in the case of any other offering, to an amount no less than thirty
percent (30%) of all shares to be included in such offering; PROVIDED, HOWEVER,
that the number of shares of Registrable Securities to be included in such
underwriting shall not be reduced unless all other stockholder securities are
first entirely excluded from the underwriting. The Company shall so advise all
Holders requesting to be included in the registration and underwriting, and the
number of shares of Registrable Securities that may be included in the
registration and underwriting shall be allocated among all Holders requesting to
be included in the registration and underwriting in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held by them at
the time of filing the registration statement. To facilitate the allocation of
shares in accordance with the above provisions, the Company or the underwriters
may round the number of shares allocated to any Holder to the nearest 100
shares. If any Holder disapproves of the terms of any such underwriting, such
person may elect to withdraw therefrom by written notice to the Company.

                           (c) RIGHT TO TERMINATE REGISTRATION. The Company
shall have the right to terminate or withdraw any registration initiated by it
under this Section 5.2 prior to the effectiveness of such registration whether
or not any Holder has elected to include securities in such registration.

                  5.3 REGISTRATION ON FORM S-3.

                           (a) REQUEST FOR REGISTRATION. In case the Company
shall receive from any Holder or Holders (the "S-3 INITIATING HOLDERS") a
written request that the Company file a registration statement on Form S-3 (or
any successor form to Form S-3) for a public offering of shares of the
Registrable Securities the aggregate price to the public of which, net of
underwriting discounts and commissions, would exceed $500,000 (Five Hundred
Thousand U.S. Dollars), and the Company is a registrant entitled to use Form S-3
to register the Registrable Securities for such an offering, the Company shall
use commercially reasonable efforts to cause such Registrable Securities to be
registered for the offering on such form and to cause such Registrable
Securities to be qualified in such jurisdictions as the S-3 Initiating Holders
may reasonably request; PROVIDED, HOWEVER, that the Company shall not be
required to effect more than one (1) registration pursuant to this Section 5.3
in any twelve month period. If such offer is to be an underwritten offer, the
underwriters must be reasonably acceptable to both the S-3 Initiating Holders
and the Company. The Company shall inform the other Holders of the proposed
registration and offer them the opportunity to participate. In the event the
registration is proposed to be part of a firm commitment underwritten public
offering, the substantive provisions of Section 5.1(b) shall be applicable to
each such registration initiated under this Section 5.3.

                           (b) Notwithstanding the foregoing, the Company shall
not be obligated to take any action pursuant to this Section 5.3:

                                      C-7


                                    (i) Following the filing of, and for one
hundred eighty (180) days immediately following the effective date of, any
registration statement pertaining to securities of the Company (other than a
registration of securities in a Rule 145 transaction or with respect to an
employee benefit plan), provided that the Company is actively employing in good
faith commercially reasonable efforts to cause such registration statement to
become effective;

                                    (ii) Within twelve (12) months after the
Company has effected a registration pursuant to this Section 5.3, and such
registration has been declared or ordered effective; or

                                    (iii) If the Company shall furnish to the
S-3 Initiating Holders a certificate signed by the President of the Company (i)
giving notice of its bona fide intention to effect the filing of a registration
statement with the Commission within the next sixty (60) days, or (ii) stating
that, in the good faith judgment of the Board of Directors, it would be
seriously detrimental to the Company or its stockholders for a registration
statement to be filed in the near future, then the Company's obligation to use
its commercially reasonable efforts to file a registration statement shall be
deferred one or more times for a period not to exceed one hundred twenty (120)
days from the receipt of the request to file such registration by the S-3
Initiating Holders, PROVIDED, HOWEVER, that the Company may not exercise this
deferral right more than once per twelve (12) month period.

                  5.4 SUBSEQUENT REGISTRATION RIGHTS.

                           (a) Without the consent of any holder of Registrable
Securities hereunder, the Company may grant to any holder of securities of the
Company registration rights inferior to those granted hereunder.

                           (b) The Company shall not enter into any agreement
granting any holder or prospective holder of any securities of the Company
registration rights superior to or on a pari passu basis with the rights granted
the Holders hereunder without the written consent of the Holders of a majority
of the Registrable Securities.

                  5.5 EXPENSES OF REGISTRATION. All Registration Expenses
incurred in connection with registrations pursuant to Sections 5.1, 5.2 and 5.3
shall be borne by the Company. Notwithstanding the foregoing, in the event that
Initiating Holders cause the Company to begin a registration pursuant to Section
5.1, and the request for such registration is subsequently withdrawn by the
Initiating Holders or such registration is not completed due to failure to meet
the net proceeds requirement set forth in such section or is otherwise not
successfully completed due to no fault of the Company, all Holders shall be
deemed to have forfeited their right to one registration under Section 5.1
unless (i) the Initiating Holders pay for, or reimburse the Company for, the
Registration Expenses incurred in connection with such withdrawn or incomplete
registration or (ii) such withdrawal is based upon material adverse information
relating to the Company that is different from the information known or
available (upon request from the Company or otherwise) to the Holders requesting
registration at the time of their request for registration. Unless otherwise
stated, all Selling Expenses relating to securities registered on behalf of the
Holders and all other registration expenses shall be borne by the Holders of
such securities pro rata on the basis of the number of shares so registered or
proposed to be so registered.

                  5.6 REGISTRATION PROCEDURES. In the case of each registration
effected by the Company pursuant to this Agreement, the Company will keep each
Holder advised in writing as to the initiation of such registration and as to
the completion thereof. The Company will:

                           (a) Prepare and file with the Commission a
registration statement and such amendments and supplements as may be necessary
and use commercially reasonable efforts to cause such registration statement to
become and remain effective for at least ninety (90) days or until the
distribution described in the registration statement has been completed,
whichever first occurs; PROVIDED, HOWEVER, that such ninety-day (90-day) period
shall be extended for a period of time equal to the period the Holder refrains
from selling any securities included in such registration at the request of an
underwriter of Common Stock (or other securities) of the Company;

                           (b) Prepare and file with the Commission such
amendments and supplements to such registration statement and the prospectus
used in connection with such registration statement as may be necessary to
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such registration statement;

                           (c) Furnish to the Holders participating in such
registration and to the underwriters of the securities being registered such
reasonable number of copies of the registration statement, preliminary
prospectus, final prospectus and such other documents as such underwriters may
reasonably request in order to facilitate the public offering of such
securities;

                           (d) 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 Securities Act of the happening of
any event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or incomplete in the light of the
circumstances then existing, and at the request of any such seller, prepare and
furnish to such seller a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such shares, 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 or
incomplete in the light of the circumstances then existing; and

                           (e) Use its commercially reasonable efforts to cause
all such Registrable Securities registered pursuant hereunder to be listed on
each securities exchange on which similar securities issued by the Company are
then listed.

                  5.7 INDEMNIFICATION.

                           (a) The Company will indemnify each Holder, each of
its officers and directors and partners, and each person controlling such Holder
within the meaning of Section 15 of the Securities Act, with respect to which
registration has been effected pursuant to this Agreement, against all expenses,
claims, losses, damages or liabilities (or actions in respect thereof),
including any of the foregoing incurred in settlement of any litigation,
commenced or threatened, arising out of or based on any untrue statement (or


                                      C-9


alleged untrue statement) of a material fact contained in any registration
statement, prospectus, offering circular or other document, or any amendment or
supplement thereto, incident to any such registration, or based on any omission
(or alleged omission) to state therein a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, or any violation by the
Company of the Securities Act, the Exchange Act, state securities laws or any
rule or regulation promulgated under such laws applicable to the Company in
connection with any such registration, and the Company will reimburse each such
Holder, each of its officers and directors, and each person controlling such
Holder, for any legal and any other expenses reasonably incurred, as such
expenses are incurred, in connection with investigating, preparing or defending
any such claim, loss, damage, liability or action, provided that the Company
will not be liable in any such case to the extent that any such claim, loss,
damage, liability or expense arises out of or is based on any untrue statement
or omission or alleged untrue statement or omission, made in reliance upon and
in conformity with written information furnished to the Company by an instrument
duly executed by such Holder or controlling person, and stated to be
specifically for use therein.

                           (b) Each Holder will, if Registrable Securities held
by such Holder are included in the securities as to which such registration is
being effected, indemnify the Company, each of its directors and officers, other
holders of the Company's securities covered by such registration statement, each
person who controls the Company within the meaning of Section 15 of the
Securities Act, and each other such Holder, each of its officers and directors
and each person controlling such Holder within the meaning of Section 15 of the
Securities Act, against all claims, losses, damages and liabilities (or actions
in respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, or any violation by
the Holder of the Securities Act, the Exchange Act, state securities laws or any
rule or regulation promulgated under such laws applicable to the Holder, and
will reimburse the Company, such other Holders, such directors, officers,
persons, underwriters or control persons for any legal or any other expenses
reasonably incurred, as such expenses are incurred, in connection with
investigating or defending any such claim, loss, damage, liability or action,
but in the case of the Company or the other Holders or their officers, directors
or controlling persons, only to the extent that such untrue statement (or
alleged untrue statement) or omission (or alleged omission) is made in such
registration statement, prospectus, offering circular or other document in
reliance upon and in conformity with information furnished to the Company by
such Holder. Notwithstanding the foregoing, the liability of each Holder under
this Section 5.7(b) shall be limited in an amount equal to the initial public
offering price of the shares sold by such Holder, unless such liability arises
out of or is based on willful misconduct or fraud by such Holder.

                           (c) Each party entitled to indemnification under this
Section 5.7 (the "INDEMNIFIED PARTY") shall give notice to the party required to
provide indemnification (the "INDEMNIFYING PARTY") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement unless the failure to


                                      C-10


give such notice is materially prejudicial to an Indemnifying Party's ability to
defend such action and provided further, that the Indemnifying Party shall not
assume the defense for matters as to which there is a conflict of interest or
there are separate and different defenses. No Indemnifying Party, in the defense
of any such claim or litigation, shall, except with the consent of each
Indemnified Party (whose consent shall not be unreasonably withheld), consent to
entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

                           (d) If the indemnification provided for in this
Section 5.7 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 result 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.

                  5.8 INFORMATION BY HOLDER. Each Holder included in any
registration shall furnish to the Company such information regarding such
Holder, the Registrable Securities held by such Holder and the distribution
proposed by such Holder as the Company may reasonably request in writing and as
shall be reasonably required in connection with any registration referred to in
this Agreement.

                  5.9 RULE 144 REPORTING. With a view to making available the
benefits of certain rules and regulations of the Commission that may at any time
permit the sale of the Restricted Securities to the public without registration,
after such time as a public market exists for the Common Stock, the Company
agrees to use commercially reasonable efforts to:

                           (a) Make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act, at
all times after the effective date that the Company becomes subject to the
reporting requirements of the Securities Act or the Exchange Act;

                           (b) File with the Commission in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements); and


                                      C-11


                           (c) So long as a Holder owns any Restricted
Securities, to furnish to the Holder forthwith upon request a written statement
by the Company as to its compliance with the reporting requirements of said Rule
144 (at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents of the Company and other
information in the possession of or reasonably obtainable by the Company as the
Holder may reasonably request in availing itself of any rule or regulation of
the Commission allowing the Holder to sell any such securities without
registration.

                  5.10 TERMINATION OF REGISTRATION RIGHTS. The rights granted
pursuant to Sections 5.1, 5.2 and 5.3 of this Agreement shall terminate as to
any Holder upon the earlier of (i) the date five (5) years after the effective
date of a Qualified Initial Public Offering and (ii) the date such Holder is
able to immediately sell all shares of Registrable Securities held by such
Holder under Rule 144 during any three (3) month period.

         6. FINANCIAL INFORMATION RIGHTS.

                  6.1 The Company will provide the following documents to each
Continuing Holder, if any:

                           (a) as soon as practicable, but in any event within
ninety (90) days after the end of each fiscal year of the Company commencing
with the fiscal year ending December 31, 2004 a consolidated balance sheet as of
the end of such fiscal year, and statements of operations and cash flow for such
fiscal year. Such year-end financial reports shall be in reasonable detail,
prepared in accordance with generally accepted accounting principles ("GAAP"),
and, if so directed by the Company's Board of Directors, audited and certified
by independent public accountants of the Company;

                           (b) within forty-five (45) days of the end of each
fiscal quarter, an unaudited statement of operations and consolidated balance
sheet as of the end of such fiscal quarter, in reasonable detail and prepared in
accordance with GAAP, subject to year end audit adjustments and the absence of
footnotes;

                           (c) at least forty-five (45) days prior to the end of
each fiscal year, an operating budget forecasting the Company's revenues,
expenses, and cash position on a month-to-month basis for the next fiscal year
and any other budgets or revised budgets when and as prepared by the Company;
and

                           (d) such other documents generally distributed or
made available to the Company's stockholders; PROVIDED, HOWEVER, that the
Company shall not be obligated to provide information that it deems in good
faith to be proprietary or confidential.

                   6.2 The Company will permit each Continuing Holder to visit
and inspect any of the properties of the Company, including its books of account
and other records (and make copies thereof and take extracts therefrom), and to
discuss its affairs, finances and accounts with the Company's officers and its
independent public accountants, all at such reasonable times and upon reasonable
notice, but no more often than once every quarter.


                                      C-12


                   6.3 Each Investor or transferee of rights under this Section
6 acknowledges and agrees that any information obtained pursuant to this Section
6 that may be considered nonpublic information will be maintained in confidence
by such Investor or transferee and will not be utilized by such Investor or
transferee in connection with purchases or sales of the Company's securities
except in compliance with applicable state and Federal securities laws.

                   6.4 The covenants of the Company set forth in this Section 6
shall terminate and be of no further force or effect upon the earliest to occur
of (i) the closing of a Qualified Initial Public Offering, (ii) the sale of all
or substantially all of the assets of the Company or the acquisition of the
Company by another entity by means of merger or consolidation resulting in the
exchange of the outstanding shares of the Company for securities or
consideration issued, or caused to be issued, by the acquiring entity or its
subsidiary, unless the stockholders of the Company hold at least 50% of the
voting power of the surviving entity in such a transaction, or (iii) the Company
otherwise becoming subject to Section 13(a) or 15(d) of the Exchange Act.

         7. LOCKUP AGREEMENT. Each Investor, Holder and transferee hereby agrees
that, in connection with the first registration of the offering of any
securities of the Company under the Securities Act for the account of the
Company, if so requested by any representative of the underwriters (the
"MANAGING UNDERWRITER"), such Investor, Holder or transferee shall not sell,
dispose of, transfer, make any short sale of, grant any option for the purchase
of or enter into any hedging or similar transaction with the same economic
effect as a sale of any securities of the Company during the period specified by
the Managing Underwriter (the "MARKET STANDOFF PERIOD"), with such period not to
exceed one hundred eighty (180) days following the effective date of the
registration statement of the Company filed under the Securities Act. The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period. The
Company shall use commercially reasonable efforts to place similar contractual
lockup restrictions on all capital stock issued now or hereafter to officers,
directors, employees and consultants of the Company and holders of registration
rights with respect to capital stock of the Company. The underwriters of the
Company's stock are intended third party beneficiaries of this Section 7 and
shall have the right, power and authority to enforce the provisions hereof as
though they were a party hereto.

         8. RIGHT OF FIRST OFFER.

                   8.1 The Company hereby grants to each Continuing Holder the
right of first offer to purchase its Pro Rata Share of New Securities (as
defined in this Section 8) which the Company may, from time to time, propose to
sell and issue. A "PRO RATA SHARE," for purposes of this right of first offer,
equals the proportion that the total number of shares of Common Stock then held
by the Holder bears to the total number of shares of Common Stock then
outstanding. Each Continuing Holder shall have a right of over-allotment such
that if any Holder fails to exercise its rights hereunder to purchase its pro
rata share of New Securities, the other Continuing Holders may purchase the
non-purchasing Holder's portion on a pro rata basis within ten (10) days from
the date such Holder receives notice that such non-purchasing Holder fails to
exercise its right hereunder to purchase its pro rata share of New Securities.

                   8.2 By entering into this Agreement each Holder hereby waives
any current or future right of first offer to purchase the Company's securities
(the "WAIVER") other than the rights set forth in this Agreement and in the
First Refusal Agreement of even date herewith.


                                      C-13


                   8.3 Except as set forth below, "NEW SECURITIES" shall mean
any shares of capital stock of the Company, including Common Stock and any
series of preferred stock, whether now authorized or not, and rights, options or
warrants to purchase said shares of Common Stock or preferred stock, and
securities of any type whatsoever that are, or may become, convertible into or
exchangeable for said shares of Common Stock or preferred stock. Notwithstanding
the foregoing, "NEW SECURITIES" does not include stock issued and issuable: (i)
to employees, consultants, officers or directors pursuant to stock option, stock
grant, stock purchase, or similar plans and arrangements, including without
limitation upon the exercise of options thereunder, approved by the Board of
Directors; (ii) to equipment lessors, banks, financial institutions or similar
entities in transactions approved by the Board of Directors, the principal
purpose of which is other than the raising of capital; (iii) in a registered
public offering by the Company; (iv) in a merger or acquisition that is approved
by the Board of Directors; (v) upon any stock split, stock dividend,
recapitalization or similar event; or (vi) upon exercise or conversion of
securities with respect to which the Continuing Holders previously had an
opportunity to exercise the right of first offer pursuant to this Section 8.

                   8.4 In the event the Company proposes to undertake an
issuance of New Securities, it shall give each Continuing Holder written notice
of its intention, describing the amount and type of New Securities, and the
price and terms upon which the Company proposes to issue the same. Each
Continuing Holder shall have twenty (20) days from the date of receipt of any
such notice to agree to purchase up to its respective Pro Rata Share of such New
Securities for the price and upon the terms specified in the notice by giving
written notice to the Company and stating therein the quantity of New Securities
to be purchased.

                   8.5 In the event the Continuing Holders fail to exercise
fully the right of first offer within said twenty-day (20-day) period and after
the expiration of the ten-day (10-day) period for the exercise of the
over-allotment provisions of this Section 8, the Company shall have one hundred
twenty (120) days thereafter to sell or enter into an agreement (pursuant to
which the sale of New Securities covered thereby shall be closed, if at all,
within one hundred twenty (120) days from the date of said agreement) to sell
the New Securities respecting which the Holders' right of first offer option set
forth in this Section 8 was not exercised, at a price and upon terms no more
favorable to the purchasers thereof than specified in the Company's notice to
Holders pursuant to Section 8.4. In the event the Company has not sold within
said one hundred twenty day (120-day) period or entered into an agreement to
sell the New Securities within one hundred twenty day (120-day) period (or sold
and issued New Securities in accordance with the foregoing within one hundred
twenty (120) days from the date of said agreement), the Company shall not
thereafter issue or sell any New Securities, without first again offering such
securities to the Continuing Holders in the manner provided in Section 8.4
above.

                   8.6 The provisions of this Section 8 will terminate and be of
no further force or effect upon the earlier to occur of (i) the closing of a
Qualified Initial Public Offering or (ii) the sale of all or substantially all
of the assets of the Company or the acquisition of the Company by another entity
by means of merger or consolidation resulting in the exchange of the outstanding
shares of the Company for securities or consideration issued, or caused to be
issued, by the acquiring entity or its subsidiary, unless the stockholders of
the Company hold at least 50% of the voting power of the surviving entity in
such a transaction.


                                      C-14


         9. REDEMPTION.

                   9.1 The Purchaser shall have the option, at any time (not
more than once) on or prior to October 7, 2004, to sell to the Company, and upon
exercise of such option by the Purchaser, subject to Section 9.3 below, the
Company shall be obligated to purchase from the Purchaser, all of the Common
Stock held by the Purchaser by paying a price equal to $0.0001 per share (the
"REDEMPTION PRICE"); PROVIDED that this right, which is hereinafter referred to
as the "Redemption," shall be exercisable by the Purchaser if, and only if, the
Company's management has failed to provide evidence, satisfactory to the
Purchaser in its reasonable good faith determination, of interest by a top 10
pharmacy retail chain in the purchase of an automated dispensing machine from
the Company for retail pharmacy prescriptions.

                   9.2 The Redemption shall be subject to the Company's receipt
of requisite consents and compliance with applicable law. In the event the
Company is unable to effect the Redemption due to the foregoing, the Company
shall use commercially reasonable efforts to obtain such consents and/or comply
with such law (as applicable) in order to effect the Redemption as soon as
reasonably practicable. In addition, the Redemption shall be subject to and
occur concurrently with the Company's (i) repayment of the principal
("PRINCIPAL") and interest ("INTEREST") outstanding under the Promissory Note in
accordance with Section 3(c) thereof and (ii) payment of any bonus to William
Holmes that is required under the Employment Agreement in accordance with
Section 2 thereof ("BONUS").

                   9.3 The Redemption shall be exercised by written notice
signed by the Purchaser and delivered to the Company as provided in Section 17.
Such notice shall identify the number of shares of Common Stock to be sold to
the Company, the amount of Principal and Interest to be repaid and shall notify
the Company of the time, place and date for settlement of such sale and
repayment, which shall be scheduled by the Purchaser within ninety (90) days
following the date of such notice. Subject to Section 9.2, the Company shall
pay, on the date of settlement specified in such notice and upon the Purchaser's
surrender to the Company of the certificate or certificates representing such
shares, for any shares of Common Stock purchased pursuant to the Redemption, at
the Purchaser's option, in cash or by offset against any indebtedness owing to
the Company by the Purchaser, or by a combination of both. Upon delivery of such
notice, payment of the Redemption Price in the form set forth in such notice and
repayment of the Principal and Interest, the Company shall become the legal and
beneficial owner of the Common Stock being redeemed and all rights and interest
therein or related thereto, and such Common Stock shall be retired and canceled
promptly after the acquisition thereof. In the event less than all the shares
represented by any stock certificate are redeemed, the Company shall promptly
issue a new certificate representing the unredeemed shares.

                   9.4 In the event the aggregate Redemption Price to be paid by
the Company for the Common Stock to be redeemed pursuant to this Section 9 plus
the amount of Principal being repaid, less any portion of such amounts that are
to be paid by offset against any indebtedness owing to the Company by the
Purchaser, is greater than (a) 92.5% of (b) (i) the aggregate of the Company's
then-current cash and cash equivalents as reflected on its most recent regularly
prepared financial statement prepared in accordance with United States generally
accepted accounting principles, less (ii) any outstanding liabilities of the
Company (including the Interest and Bonus, but excluding the Principal) (the
product of (a) and (b), the "MAXIMUM CASH AMOUNT"), then the Maximum Cash Amount
shall be used to repay the Principal and redeem that number shares of Common
Stock pursuant to this Section 9 so that the proportion that the number of


                                      C-15


shares of Common Stock redeemed bears to the total number of shares of Common
Stock then held by the Purchaser is equal to the proportion that the amount of
Principal repaid bears to the total amount of Principal then outstanding. The
Maximum Cash Amount shall be paid on the date of settlement as set forth above,
and any shares of Common Stock not redeemed due to lack of funds shall remain
outstanding and continue to be held by the Purchaser.

         10. DRAG-ALONG RIGHT.

                   10.1 In addition to compliance with the provisions of Section
8, if a Founder holding at least twenty percent (20%) of the issued and
outstanding shares of Common Stock finds a third-party acquiror for all (but not
less than all) of the shares of Common Stock then outstanding or all or
substantially all of the assets of the Company, whether such sale is by way of
purchase of Common Stock, merger, recapitalization or other similar transaction
(collectively, the "SELLING STOCKHOLDERS"), and the Investors do not exercise
their right of first refusal, if applicable, under Section 1 of the First
Refusal Agreement among the Company and the Investors to acquire all (but not
less than all) of the Selling Stockholders' Common Stock, then at the request of
the Selling Stockholders the remaining Holders (the "OTHER STOCKHOLDERS") shall
sell or otherwise transfer all of their Common Stock to such acquiror on the
same terms and conditions that apply to the sale or other transfer by the
Selling Stockholders and shall approve the transaction as set forth hereinbelow
(such transfer by the Selling Stockholders and the Other Stockholders or sale of
all or substantially all of the assets of the Company, a "SALE OF CONTROL
TRANSACTION").

                   10.2 The Selling Stockholders shall, not less than forty-five
(45) nor more than ninety (90) days prior to the proposed Sale of Control
Transaction, notify or cause to be notified, in accordance with the provisions
of Section 17, each Other Stockholder and the Company in writing of such
proposed transaction. Such notice (the "DRAG-ALONG NOTICE") shall set forth: (i)
a statement that the Selling Stockholders intend to sell all of their Common
Stock, if applicable, in the proposed Sale of Control Transaction, (ii) the name
and address of the proposed acquiror, (iii) the proposed amount and form of
consideration, including per share consideration in the case of a sale of Common
Stock, and terms and conditions of payment offered by such proposed acquiror,
and (iv) that the proposed acquiror has been informed of the drag-along right
provided by this Section 10 and has agreed to participate in the proposed Sale
of Control Transaction in accordance with the terms hereof. The closing of the
proposed Sale of Control Transaction must occur within one hundred twenty (120)
days after the date the Drag-Along Notice was first delivered to the Company and
each Other Stockholder. If for any reason the closing of the proposed Sale of
Control Transaction does not occur (other than by reason of material breach or
violation by a participating Other Stockholder of its representations,
warranties, covenants, agreements or obligations under its purchase agreement
with the proposed acquiror that are a condition to the closing thereunder)
within one hundred twenty (120) days after such date, then (x) each Other
Stockholder may elect to withdraw from the proposed Sale of Control Transaction
and (y) the Selling Stockholders may not close any similar transaction with the
proposed acquiror without first complying with the provisions of this Section
10.

                   10.3 All Holders further agree to timely take such other
actions as the Selling Stockholders may reasonably request in connection with
the approval of the consummation of a sale or other transfer in which they are
obligated to participate pursuant to this Section 10, including voting all of
their Common Stock in favor of such sale, waiving any dissenters' rights, and
executing such agreements, powers of attorney, voting proxies or other documents

                             FIRST REFUSAL AGREEMENT

This First Refusal Agreement (the "AGREEMENT") is entered into as of April 7,
2004 by and among Distributed Delivery Networks Corporation, a Delaware
corporation (the "COMPANY"), Amistar Corporation, a California corporation (the
"PURCHASER"), and William Holmes and David Blackburn (President, Harbour

governing the transfer of the capital stock held by the Purchaser and the
Founders.

                                    AGREEMENT

representations, warranties, covenants and conditions set forth in this
Agreement, the parties mutually agree as follows:

         1. RIGHT OF FIRST REFUSAL.

least ten percent (10%) of the Company's Common Stock then outstanding, are
hereby granted a right of first refusal with respect to any proposed disposition
of shares of capital stock of the Company owned by any Founder (the person
proposing such disposition, the "TRANSFEROR"). No Founder shall transfer,
assign, hypothecate, encumber, pledge or otherwise alienate any such shares
unless such Founder shall have complied with the terms herein.

desires to accept a bona fide third-party offer for the transfer of shares of
capital stock owned by such Transferor (the "TARGET SHARES"), the Transferor
shall promptly (i) deliver to the Corporate Secretary of the Company and the
other Investors written notice (the "DISPOSITION NOTICE") of the terms and
conditions of the offer, including the purchase price and the identity of the
third-party offeror, and (ii) provide satisfactory proof that the disposition of
the Target Shares to such third-party offeror would not be in contravention of
the provisions set forth in this Agreement. The Disposition Notice shall certify
that the Transferor has received a firm offer from the third party offeror and
in good faith believes a binding agreement for the transfer is obtainable on the
terms set forth in the Disposition Notice. The Disposition Notice shall also
include a copy of any written proposal, term sheet or letter of intent or other
agreement relating to the proposed transfer.

                  (b) Exercise of Right by Company. If permissible pursuant to
applicable law, the Company (or its assignees) shall, for a period of ten (10)
days following receipt of the Disposition Notice (the "COMPANY EXERCISE


                                      E-1


PERIOD"), have the right to repurchase any or all of the Target Shares specified
in the Disposition Notice upon the same terms and conditions specified therein.
Such right shall be exercisable by delivery of written notice (the "COMPANY
EXERCISE NOTICE") to the Transferor and the other Investors prior to the
expiration of the Company Exercise Period. If such right is exercised with
respect to all the Target Shares specified in the Disposition Notice, then the
Company shall effect the repurchase of the Target Shares, including payment of
the purchase price, not more than ten (10) business days after delivery of the
Company Exercise Notice; and at such time the Transferor shall deliver to the
Company the certificates representing the Target Shares to be repurchased, each
certificate to be properly endorsed for transfer. If the Company fails to
purchase all of the Target Shares by exercising the right granted in this
Section 1 within the period provided, the Target Shares shall be subject to the
rights granted to the Investors pursuant to this Agreement.

                  (c) Non-Exercise of Right by Company. In the event the Company
Exercise Notice is not given by the Company to the Transferor and the other
Investors within the Company Exercise Period, the Company shall be deemed to
have waived its right of first refusal.

                  (d) Exercise of Right by the Continuing Purchaser. Subject to
the rights of the Company set forth in Section 1(b), the Purchaser, so long as
the Purchaser continues to hold at least ten percent (10%) of the Company's
Common Stock then outstanding (the "CONTINUING PURCHASER"), shall, for a period
of twenty (20) days from receipt of the Disposition Notice (the "PURCHASER
EXERCISE PERIOD"), have the right to purchase all, or the remaining balance
after the Company's repurchase of some of the Target Shares (in either case, the
"PURCHASER REMAINING SHARES"), upon the terms and conditions specified in the
Disposition Notice. The Continuing Purchaser may exercise such purchase option
and, thereby, purchase all or any portion of the Purchaser Remaining Shares, by
notifying the Transferor, the other Investors and the Company in writing (the
"PURCHASER EXERCISE NOTICE"), before expiration of the Purchaser Exercise Period
as to the number of such shares that it wishes to purchase. The Continuing
Purchaser shall be entitled to apportion the Purchaser Remaining Shares to be
purchased among its subsidiaries and affiliates, provided that the Continuing
Purchaser notifies the Transferor of such allocation. The Continuing Purchaser
shall exercise this right of first refusal in the same manner and subject to the
same rights and conditions as the Company, as more specifically set forth in
Section 1(b).

                  (e) Non-Exercise of Right by the Continuing Purchaser. In the
event the Purchaser Exercise Notice is not given by the Continuing Purchaser to
the Transferor, the other Investors and the Company within the Purchaser
Exercise Period, the Continuing Purchaser shall be deemed to have waived its
right of first refusal.

                  (f) Exercise of Right by the Continuing Founders. Subject to
the rights of the Company set forth in Section 1(b) and the rights of the
Purchaser set forth in Section 1(d), each Founder (other than the Transferor),
so long as such Founder continues to hold at least ten percent (10%) of the
Company's Common Stock then outstanding (a "CONTINUING FOUNDER"), shall, for a
period of thirty (30) days from receipt of the Disposition Notice (the "FOUNDER
EXERCISE Period"), have the right to purchase all, or the remaining balance
after the Company's and/or the Purchaser's repurchase of some of the Target
Shares (in either case, the "FOUNDER REMAINING SHARES"), upon the terms and


                                      E-2


conditions specified in the Disposition Notice. Each Continuing Founder may
exercise such purchase option and, thereby, purchase all or any portion of the
Founder Remaining Shares, by notifying the Transferor, the other Investors and
the Company in writing (the "FOUNDER EXERCISE NOTICE"), before expiration of the
Founder Exercise Period as to the number of such shares that he wishes to
purchase. The Continuing Founders shall exercise this right of first refusal in
the same manner and subject to the same rights and conditions as the Company, as
more specifically set forth in Section 1(b).

                  (g) Non-Exercise of Right by the Continuing Founders. In the
event the Company Exercise Notice, the Purchaser Exercise Notice or the Founder
Exercise Notice with respect to any portion of the Target Shares is not given to
the Transferor within the time frames set forth in Section 1(b), 1(d) and 1(f),
the Transferor shall have a period of forty-five (45) days after expiration of
the Founder Exercise Period (the "SALE PERIOD") in which to sell the Target
Shares upon terms and conditions (including the purchase price) no more
favorable to the third-party transferee than those specified in the Disposition
Notice. The third-party transferee shall acquire the Target Shares free and
clear of subsequent rights of first refusal under this Section. In the event the
Transferor does not notify the other Investors or consummate the sale or
disposition of the Target Shares within the Sale Period, the Company's and the
Investors' first refusal rights shall continue to be applicable to any
subsequent disposition of the Target Shares by the Transferor until such right
lapses in accordance with Section 5(a) and subject to any other remedies of the
Company and the Investors under this Agreement. Furthermore, the exercise or
non-exercise of the rights of the Company and the Investors under this Agreement
to purchase Target Shares from a Transferor shall not adversely affect their
rights to make subsequent purchases from a Transferor of Target Shares.

         (h) Partial Exercise of Right. In the event that the Company or the
Investors do not exercise the right of first refusal pursuant to the terms set
forth herein with respect to all of the Target Shares described in a particular
Disposition Notice, then such right shall not apply to any Target Shares
described in such Disposition Notice.

         2. EXEMPT TRANSFERS.

                  (a) PERMITTED TRANSACTIONS. Notwithstanding the foregoing, the
first refusal rights of the Company and the Investors set forth in Section 1
shall not apply to any transfer to the ancestors, descendants, siblings or
spouse of a Transferor or to trusts for the benefit of such persons or the
Transferor; PROVIDED, HOWEVER, that the transferee under this Section 2(a) shall
furnish the Company with a written agreement to be bound by and comply with the
terms of this Agreement, and such transferred capital stock shall remain subject
to the terms of this Agreement.

                  (b) COMPANY REPURCHASE OR PUBLIC OFFERING. The provisions of
this Agreement shall not apply to the sale of any capital stock of the Company
(i) to the public pursuant to a registration statement filed with, and declared
effective by, the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "SECURITIES ACT"), or (ii) to the Company.

         3. PROHIBITED TRANSFERS.

                  (a) GRANT. In the event a Transferor should sell any capital
stock of the Company in contravention of the participation rights of the
Investors under this Agreement (a "PROHIBITED TRANSFER"), the Investors shall
have the rights provided in Section 3(b).


                                      E-3


                  (b) Put Option. In the event of a Prohibited Transfer, each
Investor shall have the option, along with other legal remedies, to sell to such
Transferor the number of shares equal to the number of shares that such Investor
would have been entitled to buy had such Prohibited Transfer been effected in
accordance with Section 1 hereof, on the following terms and conditions:

                           (1) The price per share at which the shares are to be
sold to the Transferor shall be equal to the price per share paid to the
Transferor by the third party purchaser or purchasers of the Target Shares.

                           (2) The Investor shall deliver to the Transferor
within thirty (30) days after he or it has received notice from the Transferor
or otherwise becomes aware of the Prohibited Transfer, the certificate or
certificates representing shares to be sold, each certificate to be properly
endorsed for transfer.

                           (3) The Transferor shall, within two business days
after receipt of the certificates for the purchased stock, pay the aggregate
purchase price as provided in Section 3(b)(1) therefor, by certified check or
bank draft made payable to the order of the Investor and shall reimburse the
Investor for any additional expenses, including legal fees and expenses,
incurred in effecting such purchase and sale.

         4. LEGEND REQUIREMENTS.

                  (a) LEGEND. Each certificate representing the capital stock of
the Company owned by each Investor, shall be endorsed with the following legend:

                           "THE SALE OR TRANSFER OF THE SECURITIES REPRESENTED
                           BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
                           CONDITIONS OF A CERTAIN FIRST REFUSAL AGREEMENT BY
                           AND AMONG THE REGISTERED HOLDER AND CERTAIN
                           INVESTORS. A COPY OF SUCH AGREEMENT IS ON FILE AT THE
                           PRINCIPAL OFFICE OF THE COMPANY."

                  (b) REMOVAL. The Section 4(a) legend shall be removed upon
termination of this Agreement in accordance with the provisions of Section 5(a).

         5. MISCELLANEOUS.

                  (a) TERMINATION. Notwithstanding anything to the contrary in
this Agreement, the rights and obligations of all parties hereto shall terminate
upon the earlier of (i) the Company's initial underwritten public offering
pursuant to an effective registration statement under the Securities Act
covering the offer and sale of the Company's Common Stock to the public with
gross proceeds to the Company of not less than $15,000,000 (Fifteen Million U.S.
Dollars) at a per share price of not less than $3.00 (Three U.S. Dollars) per
share (appropriately adjusted for any stock split, dividend, combination or
other recapitalization) or (ii) the sale of all or substantially all of the
assets of the Company or the acquisition of the Company by another entity by
means of merger or consolidation resulting in the exchange of the outstanding


                                      E-4


shares of the Company for securities or consideration issued, or caused to be
issued, by the acquiring entity or its subsidiary, unless the stockholders of
the Company hold at least 50% of the voting power of the surviving entity in
such a transaction.

                  (b) RECAPITALIZATION/CORPORATE TRANSACTION. All rights and
obligations of all the parties hereto shall be subject to adjustment in the
event of any stock dividend, stock split, recapitalization or other transaction
affecting the Company's outstanding Common Stock as a class, effected without
receipt of consideration, and any new, substituted or additional securities or
other property that is by reason of such transaction distributed with respect to
the shares of Common Stock owned by the Investors shall be immediately subject
to the Company's and the Investors' first refusal rights hereunder, but only to
the extent such shares are at the time covered by such rights.

                  (c) NOTICE. Any notices required in connection with this
Agreement shall be in writing and shall be deemed effectively given: (i) upon
personal delivery to the party to be notified, (ii) when sent by confirmed

business day after deposit with a nationally recognized overnight courier,
specifying next day delivery, with written notification of receipt. All notices

such address as such party may designate by ten (10) days advance written notice
to the other parties hereto.

                  (d) SEVERABILITY. In the event one or more of the provisions
of this Agreement should, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Agreement, and this Agreement
shall be construed and interpreted in such manner as to be effective and valid
under applicable law.

                  (e) AMENDMENT OR MODIFICATION. Any amendment or modification
of this Agreement shall be effective only if evidenced by a written instrument
executed by (i) all the Founders, (ii) the Purchaser and (iii) the Company.

                  (f) GOVERNING LAW. This Agreement and the rights and
obligations of the parties hereto shall be governed, construed and interpreted
in accordance with the laws of the State of California, without giving effect to
principles of conflicts of law.

                  (g) ATTORNEY'S FEES. In the event that any suit or action
(including arbitration) is instituted to enforce or interpret the terms of this
Agreement, the prevailing party in such dispute shall be entitled to recover
from the losing party its reasonable attorney's fees, costs and out-of-pocket
litigation expenses, including without limitation, expert witness fees.

                  (h) FURTHER ASSURANCES. Each party agrees to act in accordance
herewith and not to take any action that is designed to avoid the intention
hereof.

                  (i) SUCCESSORS AND ASSIGNS. This Agreement and the rights and
obligations of the parties hereunder shall inure to the benefit of, and be
binding upon, their respective successors, permitted assigns and legal
representatives.


                                      E-5


                  (j) AGGREGATION OF STOCK. All shares held or acquired by
affiliated entities or persons shall be aggregated together for the purpose of
determining the availability of any rights under this Agreement.
