                         REPRESENTATIONS AND WARRANTIES

     SECTION 2.1  REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.  The
Purchasers hereby jointly and severally represent and warrant to CDIc as
follows:

<PAGE>

          (a)  AUTHORITY.  Each of the Purchasers has the full right, power and
authority to enter into, execute, deliver and carry out the terms of this
Agreement and the transactions contemplated hereby and to perform her/his
obligations hereunder.  This Agreement constitutes the valid and binding
obligation of the Purchasers enforceable in accordance with its terms.

          (b)  CONSENTS AND APPROVALS.  All authorizations, approvals and
consents, if any, required to be obtained from, and all registrations,
declarations and filings, if any, required to be made with, all governmental
authorities and regulatory bodies to permit the Purchasers to execute and
deliver this Agreement, and to perform their obligations hereunder, have been
obtained or made, as the case may be, and all such authorizations, approvals,
consents, registrations, declarations and filings are in full force and effect.

          (c)  NO VIOLATIONS.  Neither the execution or delivery by the
Purchasers of this Agreement, nor the consummation by the Purchasers of the
transactions herein contemplated, nor the fulfillment by the Purchasers of the
terms and provisions hereof (i)will conflict with, violate or result in a breach
of, any of the terms, conditions or provisions of any law, regulation, order,
writ, injunction, decree, judgment or award of any court, governmental
department, board, agency or instrumentality or any arbitrator, applicable to
either of the Purchasers or (ii) will conflict with, violate or result in a

party.

                                       -2-

          (d)  INVESTMENT INTENT.

               (1)  Each of the Purchasers has received, carefully read and
understood the documents provided to her/him by CDIc, including CDIc's most
recent Form 10-KSB and the three following Forms 10-QSB.  Additionally, CDIc has
afforded her/him access to and ample opportunity to obtain other information
regarding CDIc.  She/he has not relied on any oral representations of any kind.

               (2)  Each of the Purchasers has such knowledge and experience in
financial and business matters (including experience with investments of a
similar nature), that she/he is capable of evaluating the merits and risks of an
investment in CDIc common stock.

               (3)  The CDIc common stock is being acquired solely for her/his
own account for investment only and not with a view to or for any resale or
distribution thereof or with any present intention of distributing or selling
all or any part of such securities.  She/he agrees that the CDIc common stock is
UNREGISTERED and may not be transferred except upon registration under the
Securities Act of 1933, and under any applicable state securities or "blue sky"
laws, or upon receipt by CDIc of evidence in form and substance reasonably
satisfactory to CDIc, to the effect that such transfer may be made without
registration under the  Securities Act of 1933 and applicable state securities
or "blue sky" laws.  The Purchasers' share certificates representing CDIc common
stock will bear a legend to that effect.  CDIc has no obligation to register the
Purchasers' CDIc common stock.

                                       -3-
<PAGE>

               (4)  Each of the Purchasers recognizes that the purchase of the
CDIc Common Stock by her/him is a speculative investment that involves a high
degree of risk and is suitable only for persons with the financial capability of
making and holding long-term investments not readily reducible to cash.

     SECTION 2.2  REPRESENTATIONS AND WARRANTIES OF CDIC.  CDIc hereby
represents and warrants as follows:

          (a)  AUTHORITY.  CDIc is a validly existing California corporation in
good standing.  CDIc has the full right, power and capacity necessary to enter
into, execute, deliver and perform its obligations under this Agreement.  This
Agreement constitutes a valid and binding agreement of CDIc, enforceable in
accordance with its terms.

          (b)  CONSENTS AND APPROVALS.  All authorizations, approvals and
consents, if any, required to be obtained from, and all registrations,
declarations and filings, if any, required to be made with, all governmental
authorities and regulatory bodies to permit CDIc to execute and deliver, and to
perform its obligations under, this Agreement have been obtained or made, as the
case may be, and all such authorizations, approvals, consents, registrations,
declarations and filings are in full force and effect.

          (c)  NO VIOLATIONS.  Neither the execution or delivery by CDIc of this
Agreement, nor the consummation by CDIc of the transactions herein contemplated,
nor the fulfillment by CDIc of the terms and provisions hereof (i) will conflict
with, violate or result in a breach of any of the terms, conditions or
provisions of any law, regulation, order, writ, injunction, decree, judgment or
award of any court, governmental department, board, agency or instrumentality or
any arbitrator, applicable to CDIc, or

                                       -4-
<PAGE>

(ii) will conflict with, violate or result in a breach of, or constitute a
default under, any of the terms, conditions or provisions of any agreement or
instrument to which CDIc is a party.

          (d)  CAPITALIZATION.   The current capitalization of CDIc consists of
50,000,000 shares of authorized Common Stock, 29,377,076 shares of which are
outstanding, and 500,000 shares of Preferred Stock, 235,944 shares of which are
outstanding.  In addition, options to purchase 1,168,000 shares of Common Stock
are outstanding.

          (e)  NO MISSTATEMENTS OR OMISSIONS.    The oral and written
information regarding CDIc provided, inside and outside this Agreement, by CDIc
to the Purchasers does not contain any misstatements of a material fact or omit
to state anything necessary to avoid making materially misleading the statements
which were provided.

                                  ARTICLE III.

                                    COVENANTS

     SECTION 3.1    MARKET STAND-OFF AGREEMENT.  Each of the Purchasers hereby
agrees that, during the period of duration (not to exceed 180 days) specified by
CDIc and an underwriter of Common Stock or other securities of CDIc, following
the effective date of a registration statement of CDIc filed under the
Securities Act of 1933, she/he will not, to the extent requested by CDIc and
such underwriter, 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 (other than to transferees or donees who agree
to be similarly bound) any securities of CDIc held by

                                       -5-
<PAGE>

her/him at any time during such period; PROVIDED, HOWEVER, that all officers and
directors of CDIc enter into similar agreements.  In order to enforce the
foregoing covenant, CDIc may impose stop-transfer instructions with respect to
the Purchasers' CDIc Common Stock until the end of such period.  CDIc is NOT
representing to the Purchasers that it will engage in any such public offering
by any particular date, or ever.

     SECTION 3.2    RESCISSION/REINVESTMENT OPTION.  CDIc is considering making
in the near future a private placement of securities, which may or may not be on
the same terms and conditions as this Agreement.  CDIc shall have no obligation
to the Purchasers to make any private placement of securities.  Nonetheless, if
within the next four months CDIc does make through an outside placement agent a
private placement of securities in excess of $2,000,000, not counting this
Agreement's $375,000 and a recent direct investment of approximately $250,000,
CDIc shall so notify the Purchasers in writing and the Purchasers shall have an
option, which shall expire 15 days after such notice, to rescind their purchase
of CDIc common stock under this Agreement on condition that they immediately
reinvest the $375,000 in the CDIc securities offered in the private placement,
on whatever terms and conditions are established for the private placement.

                                   ARTICLE IV.

                                  MISCELLANEOUS

     SECTION 4.1    ENTIRE AGREEMENT.  This Agreement constitutes the entire
agreement among the parties pertaining to the subject matter hereof and
completely supersedes all prior or contemporaneous agreements, understandings,
arrangements,

                                       -6-
<PAGE>

commitments, negotiations and discussions of the parties, whether oral or
written (all of which shall have no substantive significance or evidentiary
effect).  Each party acknowledges, represents and warrants that this Agreement
is fully integrated and not in need of parol evidence in order to reflect the
intentions of the parties.  The parties specifically intend that the literal

concerning the parties' intent.

     SECTION 4.2  WAIVERS.  The failure at any time of any party hereto to
require performance by any other party hereto of any responsibility or
obligation required by this Agreement shall in no way affect a party's right to
require such performance at any time thereafter, nor shall the waiver by the
party of a breach of any provision of this Agreement by any other party
constitute a waiver of any other breach of the same or any other provision of
this Agreement nor constitute a waiver of the responsibility or obligation
itself.

     SECTION 4.3  ASSIGNABILITY.  This Agreement shall be binding upon and inure
to the benefit of the successors and assigns of each party hereto, and, for S.
Duff, her administrators, executors, personal representatives, beneficiaries,
