Item 5.  Other Events.

On August 18, 1998, HealthDesk Corporation ("HealthDesk"), MC Informatics, Inc.
("MCIF"), and MC Acquisition Corporation, a wholly-owned subsidiary of
HealthDesk ("Sub"), entered into an Agreement and Plan of Reorganization (the
"Agreement"). Under the Agreement, Sub will merge with and into MCIF and the
holders of MCIF capital stock will be entitled to receive approximately 5
million shares of the Company's Common Stock; provided, however, that in no
event shall HealthDesk issue less than forty percent (40%) of HealthDesk's
capital stock in this transaction. The Agreement has been approved by the
respective Boards of Directors of HealthDesk and MCIF, and the transactions
contemplated thereby are subject to the approval of the respective shareholders
of HealthDesk and MCIF and other customary closing conditions. The acquisition
contemplated by the Agreement is intended to qualify as a tax-free
reorganization.

On September 29, 1998, HealthDesk, Patient Infosystems, Inc. ("PATI") and
Patient Infosystems Acquisition Corp. ("Buyer") entered into an Asset Purchase
Agreement (the "Asset Agreement") pursuant to which HealthDesk sold
substantially all of its assets to Buyer and in exchange, Buyer agreed to
deliver to HealthDesk at the closing approximately $635,000. In addition, Buyer
has agreed to assume and discharge liabilities and obligations but only to the
extent that such liabilities or obligations accrue on or after the closing date.

                  2.2 Cancellation of Shares and Delivery of Consideration.

                      (a) At the Effective Time, each share of MCI capital
stock, if any, that is owned directly or indirectly by MCI shall be canceled and
no cash or other consideration shall be delivered in exchange therefor.

                      (b) At the Effective Time, each MCI Share (other than
shares owned directly or indirectly by MCI) shall, by virtue of the Merger, and
without further action on the part of any holder thereof, be converted and
exchanged in accordance with the Exchange Ratio.

                      (c) At the Effective Time, each share of capital stock of
Sub outstanding immediately prior to the Merger shall, by virtue of the Merger,
and without further action on the part of any holder thereof, continue to be
issued and shall be converted into one share of MCI common stock outstanding
after the Merger.

                      (d) The Exchange Ratio shall be adjusted to reflect the
effect of any stock split, reverse split, stock dividend (including any dividend
or distribution of securities convertible into HealthDesk Common Stock or MCI
Common Stock), reorganization, recapitalization or other like change with
respect to HealthDesk Common Stock or MCI Common Stock occurring after the date
hereof and prior to the Effective Time.

                      (e) No fraction of a share of HealthDesk Common Stock
shall be issued, but in lieu thereof each holder of MCI Shares who would
otherwise be entitled to a fraction of a share of HealthDesk Common Stock (after
aggregating all fractional shares of HealthDesk Common Stock to be received by
such holder) shall receive from HealthDesk an amount of cash (rounded to the
nearest whole cent) equal to the product of (i) such fraction, multiplied by
(ii) the average closing price of a share of HealthDesk Common Stock for the
five most recent days that HealthDesk Common Stock has traded ending on the
trading day immediately prior to the Effective Time, as reported on the Nasdaq
SmallCap Market.

                      (f) Any Dissenting Shares shall not be converted into
HealthDesk Common Stock but shall instead be converted into the right to
Dissenting Shares pursuant to the California Corporations Code. MCI agrees that,
except with the prior written consent of HealthDesk, or as required under the
California Corporations Code, it will not voluntarily make any payment with
respect to, or settle or offer to settle, any such purchase demand. Each holder
of Dissenting Shares (a "Dissenting Shareholder") who, pursuant to the
provisions of the California Corporations Code, becomes entitled to payment for
MCI Shares shall receive payment therefor (but only after the value therefor
shall have been agreed upon or finally determined pursuant to such provisions).
If, after the Effective Time, any Dissenting Shares shall lose their status as
Dissenting Shares, HealthDesk shall issue and deliver, upon surrender by such
shareholder of certificate or certificates representing MCI Shares, the number
of shares of HealthDesk Common Stock to which such shareholder would otherwise
be entitled under this Section 2.2 less the number of shares of HealthDesk
Common Stock allocable to such shareholder that have been deposited in the
Indemnity Escrow.

                  2.3 Exchange Procedures.

                      (a) Following the Closing Date, HealthDesk shall mail to
each holder of record of certificate(s) or other documents which represent MCI
Shares (the "Certificates"), to be exchanged pursuant to Section 2.2 hereof (i)
a letter of transmittal (which shall specify that, with respect to the
Certificates, delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to HealthDesk
and shall be in such form and have such other provisions as HealthDesk shall
reasonably require) and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for HealthDesk Shares. Upon surrender of a
Certificate for cancellation to HealthDesk, together with such letter of
transmittal, duly executed, the holder of such Certificates shall be entitled to
receive in exchange therefor his pro rata allocation of the HealthDesk Shares as
to which such holder is entitled pursuant to Section 2.2 hereof. Certificates so
surrendered pursuant to this Section 2.3 shall forthwith be canceled (if not
otherwise canceled or terminated in accordance with their terms). In the event
of a transfer of ownership of MCI Shares which is not registered on the transfer
records of MCI, the appropriate number of HealthDesk Shares may be delivered to
a transferee if the Certificate representing such transferred security is
presented to HealthDesk and accompanied by all documents required to evidence
and effect such transfer and to evidence that any applicable stock transfer
taxes have been paid. Until surrendered as contemplated by this Section 2.3,
each Certificate shall be deemed at any time after the Effective Time to
represent solely the right to receive upon such surrender that number of
HealthDesk Shares (without interest and subject to applicable withholding,
escheat and other laws) to which such holder is entitled.

                      (b) Notwithstanding anything to the contrary in this
Section 2.3, none of HealthDesk, the Surviving Corporation or any party hereto
shall be liable to a holder of MCI Shares for any amount properly paid to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

                      (c) The HealthDesk Shares paid in accordance with the
terms hereof shall be deemed to be in full satisfaction of all rights pertaining
to such MCI Shares, and there shall be no further registration of transfers on
the records of the Surviving Corporation of MCI Shares. If, after the Effective
Time, Certificates are presented to the surviving Corporation for any reason,
they shall be canceled and exchanged as provided in Section 2.2.

                      (d) In the event any Certificates evidencing MCI Shares
shall have been lost, stolen or destroyed, HealthDesk shall issue in exchange
for such lost, stolen or destroyed Certificates, upon the making of an affidavit
of that fact by the holder thereof, such holders pro rata allocation of
HealthDesk Shares, as may be required pursuant to Section 2.2; provided,
however, that HealthDesk may, in its discretion and as a condition precedent to
the issuance thereof, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against HealthDesk with respect to
the Certificates alleged to have been lost, stolen or destroyed.

obligated under any charter, bylaw or contract provision or any license,
franchise or permit, or subject to any order or decree, which would be breached
or violated by or in conflict with its executing and carrying out this Agreement
and the transactions contemplated hereunder and under the Transaction Documents.
This Agreement is, and each of the other Transaction Documents to which MCI will

obligation of MCI enforceable in accordance with their respective terms, subject
to (i) laws of general application relating to bankruptcy, insolvency, and the
relief of debtors, and (ii) rules of law governing specific performance,

                  3.4 Financial Statements.

forth the following: (i) the balance sheet and consolidated statements of income
and changes in financial condition for the fiscal years ended December 31, 1996
and 1997 and for the five month period ended May 31, 1998 for the LLC and (ii)
MCI's consolidated unaudited balance sheet dated as of May 31, 1998 (the "MCI

collectively, the "MCI Financial Statements").

                      (b) The MCI Financial Statements are complete and in

(absolute or contingent) of a nature required or customarily reflected in a

reports by any applicable governmental agency. No state of facts exists or has
existed which would constitute grounds for the assessment of any penalty or of
any further Tax liability beyond that shown on the respective Tax reports or
returns. There are no outstanding agreements or waivers extending the statutory
period of limitation applicable to any federal, state or local income Tax return
or report for any period.

                      (b) All Taxes which MCI has been required to collect or

taxable income for any Tax period (or portion thereof) ending after the Closing

any jurisdiction requiring Tax adjustments as a result of a change in method of
accounting implemented by MCI prior to the Closing Date for any Tax period (or
portion thereof) ending on or before the Closing Date or pursuant to the
provisions of any agreement entered into by MCI prior to the Closing Date with
any taxing authority with regard to the Tax liability of MCI for any Tax period
(or portion thereof) ending on or before the Closing Date.

                  3.19 Compliance with Environmental Requirements. MCI has
obtained all permits, licenses and other authorizations which are required under
federal, state and local laws applicable to MCI and relating to pollution or
protection of the environment, including laws or provisions relating to
emissions, discharges, releases or threatened releases of pollutants,
contaminants, or hazardous or toxic materials, substances, or wastes into air,
surface water, groundwater, or land, or otherwise relating to the manufacture,
processing, distribution, use, treatment, storage, disposal, transport, or
handling of pollutants, contaminants or hazardous or toxic materials,
substances, or wastes. Except as set forth in Section 3.19 of the MCI Disclosure
Schedule, MCI is in compliance with all terms and conditions of the required
permits, licenses and authorizations. Except as set forth in Section 3.19 of the
MCI Disclosure Schedule, MCI is not aware of, nor has MCI received written
notice of, any conditions, circumstances, activities, practices, incidents, or
actions which may form the basis of any claim, action, suit, proceeding,
hearing, or investigation of, by, against or relating to MCI, based on or
related to the manufacture, processing, distribution, use, treatment, storage,
disposal, transport, or handling, or the emission, discharge, release or
threatened release into the environment, of any pollutant, contaminant, or
hazardous or toxic substance, material or waste.

Except as disclosed in Section 3.19 of the MCI Disclosure Schedule,

                       (a) No Environmental Activity has occurred in the
business of MCI or on or in relation to any premises currently or formerly used
by MCI which may cause MCI to incur expenses or costs for the elimination,
neutralization or amelioration of the results of the Environmental Activity or
become liable for compensation to any third party.

                       (c) There are no underground storage tanks or surface
impoundments at, on, or under premises formerly or currently used by MCI.

                       (d) MCI has maintained all environmental and operating

required by any Environmental Laws. Section 3.19 of the MCI Disclosure Schedule
lists each environmental permit and each Environmental Audit conducted with
respect to MCI or its premises while occupied by either of them. An
"Environmental Audit" shall mean any evaluation, inspection, assessment, study
or test performed at the request of or on behalf of a governmental authority,
including but not limited to, a public liaison committee, as well as a
self-evaluation, whether or not required by Environmental Law.

actions, and meetings of the shareholders, the board of directors and any
committees thereof; (iii) all permits, orders, and consents issued by any

applications for such permits, orders, and consents; and (iv) the stock transfer
books of MCI setting forth all transfers of any capital stock. The corporate
minute books, stock certificate books, stock registers and other corporate

contained therein are the true signatures of the persons purporting to have
signed the same. All actions reflected in such books and records were duly and
validly taken in compliance with the laws of the applicable jurisdiction.

                  3.21 Accuracy of Information In Information or Proxy
Statement. The information furnished by MCI to the MCI Shareholders in
connection with the solicitation of shareholder consent or proxies for the
approval and adoption of this Agreement and the approval and adoption of the
Merger shall not, on the date the Information or Proxy Statement is first mailed
to the HealthDesk shareholders, on any date subsequent thereto and prior to the
Effective Time or at the Effective Time, contain any untrue statement of a
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they are made, not
false or misleading, or omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of
consent or proxies which has become false or misleading.

                  3.22 No Brokers. Neither MCI nor any shareholder, officer or
director of MCI is obligated for the payment of fees or expenses of any broker

                  4.4 Commission Documents; Financial Statements. HealthDesk has
made available to MCI a true and complete copy of each statement, report,
registration statement, definitive proxy statement and other filings filed with
the Commission by HealthDesk since January 1, 1998; and, prior to the Effective

their terms, and neither HealthDesk nor any of its subsidiaries is in default
thereunder. As of their respective filing dates, the HealthDesk Commission
Documents compiled in all material respects with the requirements of the
Exchange Act and the Securities Act, and none of the HealthDesk Commission
Documents contained any untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances in which they were made,
not misleading, except to the extent corrected by a subsequently filed
HealthDesk Commission Document prior to the date hereof. The financial
statements of HealthDesk, including the notes thereto, included in the
HealthDesk Commission Documents (the "HealthDesk Financial Statements") were
complete and correct in all material respects as of their respective dates,
complied as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the Commission with
respect thereto as of their respective dates, and have been prepared in
accordance with generally accepted accounting principles applied on a basis
consistent throughout the periods indicated and consistent with each other
(except as may be indicated in the notes thereto or, in the case of unaudited
statements included in Quarterly Reports on Form 10-Qs, as permitted by Form
10-Q of the Commission). The HealthDesk Financial statements fairly present the
consolidated financial condition and operating results of HealthDesk and its
subsidiaries at the dates and during the periods indicated therein (subject, in
the case of unaudited statements, to normal, recurring year-end adjustments).
There has been no change in HealthDesk accounting policies except as described
in the notes to the HealthDesk Financial Statements. HealthDesk has filed in a
timely manner all reports required to be filed with the Securities and Exchange
Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act during the
12 calendar months prior to the date hereof.

                  4.5 Accuracy of Documents and Information. No representations
or warranties made by HealthDesk or Sub in this Agreement, nor any document,
written information, statement, financial statement, certificate, schedule or
exhibit furnished directly to MCI pursuant to this Agreement, taken as a whole,
contains any untrue statement of a material fact, or omits to state a material
fact necessary to make the statements or facts contained herein not misleading.

                  4.6 No Brokers. HealthDesk is not obligated to pay fees or
expenses to any broker or finder in connection with the origin, negotiation or
execution of this Agreement or in connection with any transaction contemplated

The MCI Shares are and will be, at all times until the Closing, free and clear

Shareholder's principal place of residence or place of business is set forth on
the signature page hereto.

prior to the Closing.

                  5.3 Principal Shareholder agrees that any shares in the
capital stock of MCI that Principal Shareholder purchases or with respect to
which Principal Shareholder otherwise acquired beneficial ownership after the

subject to the terms and conditions of this Agreement to the same extent as if
they constituted MCI Shares.

               6. Covenants of MCI.

                  6.1 Advice of Changes. MCI will promptly advise HealthDesk in
writing (i) of any event occurring subsequent to the date of this Agreement
which would render any representation or warranty of MCI contained in this
Agreement, if made on or as of the date of such event or the Closing Date,
untrue or inaccurate in any material respect and (ii) of any material adverse

                  6.3 Risk of Loss. Until the Closing and subject to the

best efforts to satisfy or cause to be satisfied all the conditions precedent

Regulation D under the Securities Act.

               7. Covenants of HealthDesk and Sub.

                  7.1 Advice of Changes. HealthDesk and Sub will promptly advise
MCI in writing of any event occurring subsequent to the date of this Agreement
which would render any representation or warranty of HealthDesk or Sub contained
in this Agreement, if made on or as of the date of such event or the Closing
Date, untrue or inaccurate in any material respect.

                  7.2 Regulatory Approvals. Prior to the Closing, HealthDesk and
Sub shall execute and file, or join in the execution and filing, of any
application or other document which may be necessary in order to obtain the
authorization, approval or consent of any Governmental Body, federal, state or
local, which may be reasonably required, or which MCI may reasonably request, in
connection with the consummation of the transactions contemplated by this
Agreement. Such persons and entities shall use their best efforts to obtain all
such authorizations, approvals and consents.

                  7.3 Satisfaction of Conditions Precedent. HealthDesk will use
its best efforts to satisfy or cause to be satisfied all the conditions
precedent which are set forth in Section 10, and HealthDesk will use its best
efforts to cause the transactions contemplated by this Agreement to be

all consents and authorizations of third parties and to make all filings with,
and give all notices to, third parties which may be necessary or reasonably
required on its part in order to effect the transactions contemplated hereby.

                  7.4 Listing of Additional Shares. HealthDesk shall file with
the Nasdaq Stock Market a Notification Form for Listing of Additional Shares
with respect to the HealthDesk Shares.

                  7.5 Shareholder Notes. Promptly following the Closing,
HealthDesk shall repay the outstanding note obligations of MCI to the Principal
Shareholders in an aggregate amount not to exceed $150,000. Without limiting the
generality of the foregoing, in lieu of such repayment, the Shareholders shall
have the right, which right must be elected, if at all, in writing prior to the

                                       24
<PAGE>

Closing, to (i) convert such indebtedness as of the Closing into HealthDesk
Common Stock based upon a conversion price of $0.50 per share or (ii) agree to
not have such obligations paid at that time and continue as a note payable on
such terms as may be agreed between the Principal Shareholders and HealthDesk.

                  7.6 Sale of HealthDesk Assets. The parties acknowledge that it
is the intention of HealthDesk to seek a buyer for its current operating assets
relating to its HealthDesk Online product (the "Historical HealthDesk
Business"). HealthDesk will use reasonable commercial efforts to negotiate a
sale of such assets as soon as reasonably practicable. Any proceeds of such sale
shall first be applied to satisfy liabilities and shall otherwise be retained by
HealthDesk to satisfy the minimum working capital and cash requirements set
forth herein. If HealthDesk is unable to effect such a sale or is otherwise
unable to meet the working capital and cash requirements which are a condition
to Closing, HealthDesk shall seek to raise additional equity capital; provided
however, that in such event, the number of shares issuable to the MCI
Shareholders shall be proportionately increased such that such shareholders hold
not less than forty percent (40%) of the total outstanding shares of HealthDesk
as of the Closing.

                  7.7 Maintenance of Minimum Working Capital.

                      (a) For the purposes of this Section, "Underreserved
Liabilities" shall mean (i) any specific liabilities of the Historical
HealthDesk Business which were recorded in the company's financial statements
immediately prior to the Closing ("HealthDesk Closing Balance Sheet") for which
based upon developments after the Closing it is determined were underreported in
such financial statements or (ii) the costs of satisfying third party
contractual commitments relating to the Historical HealthDesk Business in
existence at the time of the Closing which exceed the amount reserved therefor
on the HealthDesk Closing Balance Sheet; provided however, that Underreserved
Liabilities shall be offset by the amount, if any, that HealthDesk realizes from
the disposition of the Historical HealthDesk Business in excess of the amount
recorded therefor in the HealthDesk Closing Balance Sheet. If during the period
following the Closing and before December 31, 1998 Underreserved Liabilities are
discovered, which had such Underreserved Liabilities been fully reserved in the
HealthDesk Closing Balance Sheet would have resulted in HealthDesk having less
than $1 million of working capital as of immediately prior to the Closing, then
HealthDesk shall raise such additional equity capital as shall be necessary such
that if such capital had been raised prior to the Closing, HealthDesk would have
had not less than $1 million in working capital as of the Closing; provided that
HealthDesk shall be obligated to raise no more than the amount of the
Underreserved Liabilities. If HealthDesk is required to issue additional equity
securities in order to satisfy its obligations hereunder ("Additional Equity
Shares"), HealthDesk shall simultaneously issue to the MCI Shareholders, in
proportion to the number of MCI Shares held by each, a number of shares of
HealthDesk capital stock equal to two-thirds (2/3) of the number of Additional
Equity Shares.

                      (b) If, as of the Closing, the HealthDesk Closing Balance
Sheet indicates that HealthDesk's working capital is less than $1 million (the
"Shortfall"), HealthDesk covenants to use its best efforts to sell to either or
both of John Pappajohn and Edgewater Private Equities, or their related
entities, a number of shares of Common Stock of HealthDesk, at a price equal to
$0.50 per share (the "Shortfall Shares"), such that the proceeds to HealthDesk

                                       25
<PAGE>

from the sale of such securities equals the Shortfall. Notwithstanding the
foregoing, in the event HealthDesk signs an agreement regarding the sale of the
Historical HealthDesk Business, the amounts to be paid to HealthDesk pursuant to
such agreement shall be credited to HealthDesk and used to offset any Shortfall
prior to the sale of any Shortfall Shares.

               8. Mutual Covenants.

                  8.1 Confidentiality. Each party acknowledges that in the
course of the performance of this Agreement, it may obtain the Confidential
Information of the other party. The Receiving Party shall, at all times, both
during the term of this Agreement and thereafter, keep in confidence and trust
all of the Disclosing Party's Confidential Information received by it. The
Receiving Party shall not use the Confidential Information of the Disclosing
Party other than as expressly permitted under the terms of this Agreement or by
a separate written agreement. The Receiving Party shall take all reasonable
steps to prevent unauthorized disclosure or use of the Disclosing Party's
Confidential Information and to prevent it from falling into the public domain
or into the possession of unauthorized persons. The Receiving Party shall not
disclose Confidential Information of the Disclosing Party to any person or
entity other than its officers, employees, consultants and permitted
sublicensees who need access to such Confidential Information in order to effect
the intent of this Agreement and who have entered into confidentiality
agreements with such person's employer which protects the Confidential
Information of the Disclosing Party. The Receiving Party shall promptly give
notice to the Disclosing Party of any unauthorized use or disclosure of
Disclosing Party's Confidential Information. The Receiving Party agrees to
assist the Disclosing Party to remedy such unauthorized use or disclosure of its
Confidential Information, which remedies shall include injunctive relief without
the necessity of posting a bond or proving damages. These obligations shall not
apply to the extent that Confidential Information includes information which:

                      (a) is already known to the Receiving Party at the time of
disclosure, which knowledge the Receiving Party shall have the burden of
proving;

                      (b) is, or, through no act or failure to act of the
Receiving Party, becomes publicly known;

                      (c) is received by the Receiving Party from a third party
without restriction on disclosure;

                      (d) is independently developed by the Receiving Party
without reference to the Confidential Information of the Disclosing Party, which
independent development the Receiving Party will have the burden of proving;

                      (e) is approved for release by written authorization of
the Disclosing Party; or

                                       26
<PAGE>

                      (f) is required to be disclosed by a government agency to
further the objectives of this Agreement or by a proper order of a court of
competent jurisdiction; provided, however that the Receiving Party will use its
best efforts to minimize such disclosure and will consult with and assist the
Disclosing Party in obtaining a protective order prior to such disclosure.

                  8.2 Exclusivity. Until the earlier of the Closing Date and
July 20, 1998, MCI agrees that it will not (and that it will use best efforts to
assure that its employees, agents and affiliates do not on its behalf) discuss
or enter into any agreement concerning the sale or acquisition of MCI, its stock
(including by means of any public offering thereof, but excluding issuance of
stock and options to employees in the ordinary course of business consistent
with past practices) or a substantial part of its assets with any party other
than HealthDesk, and that any such discussions presently in progress will be
terminated or suspended during that period. MCI represents and warrants that it
has the legal right to terminate or suspend any such pending negotiations and
agrees to indemnify HealthDesk, its representatives and agents from and against
any claims by any party to such negotiations based upon or arising out of the
discussion or any consummation of the Merger.

                  8.3 Further Assurances. Each party agrees to cooperate fully
with the other parties and to execute such further instruments, documents and
agreements and to give such further written assurances, as may be reasonably
requested by any other party to better evidence and reflect the transactions
described herein and contemplated hereby and to carry into effect the intents
and purposes of this Agreement.

                  8.4 Tax-Free Organization. Each party shall each use its best
efforts to cause the Merger to be treated as a reorganization within the meaning
of Section 368(a) of the Code.

               9. The Closing.

                  9.1 Merger. On the date of the Closing, but not prior to the

                      (a) At any time and from time to time at or after the
Closing, the parties shall at the request of the other party execute and deliver
or cause to be executed and delivered all such assignments, consents and other
documents and take or cause to be taken all such other actions as either party
may reasonably deem necessary or desirable, in order to more fully and
effectively carry out the intents and purposes of this Agreement.

              13. Miscellaneous.

                  13.1 Governing Laws. It is the intention of the parties hereto
that the internal laws of the State of California (irrespective of its choice of

its terms, and the interpretation and enforcement of the rights and duties of
the parties hereto.

                  13.2 Binding upon Successors and Assigns. Subject to, and
unless otherwise provided in, this Agreement, each and all of the covenants,

inure to the benefit of, the permitted successors, executors, heirs,
representatives, administrators and assigns of the parties hereto.

                  13.3 Severability. If any provision of this Agreement, or the
application thereof, shall for any reason and to any extent be invalid or
unenforceable, the remainder of this Agreement and application of such provision
to other persons or circumstances shall be interpreted so as best to reasonably
effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision which will achieve, to the extent possible, the economic,
business and other purposes of the void or unenforceable provision.

                  13.4 Entire Agreement. This Agreement, the exhibits and
schedules hereto, the documents referenced herein, and the exhibits and
schedules thereto, constitute the entire understanding and agreement of the
parties hereto with respect to the subject matter hereof and thereof and
supersede all prior and contemporaneous agreements or understandings,
inducements or conditions, express or implied, written or oral, between the
parties with respect hereto and thereto. The express terms hereof control and
supersede any course of performance or usage of the trade inconsistent with any
of the terms hereof.

                  13.5 Counterparts. This Agreement may be executed in any
number of counterparts, each of which shall be an original as against any party
whose signature appears thereon and all of which together shall constitute one
and the same instrument. This Agreement shall become binding when one or more
counterparts hereof, individually or taken together, shall bear the signatures
of all of the parties reflected hereon as signatories.

                  13.6 Expenses. Except as provided to the contrary herein, each

negotiation, execution and delivery of this Agreement and the exhibits hereto.
In the event the Merger is consummated, all legal and accounting fees incurred
by MCI and the MCI Shareholders in connection with the Merger up to $25,000
shall be payable by HealthDesk upon presentation of an adequate and appropriate
bill. Any expenses in excess of such amount shall be deemed to be expenses of

become obligations of MCI, HealthDesk or the Surviving Corporation. The MCI
Shareholders shall make arrangements satisfactory to HealthDesk at or prior to
the Closing for the satisfaction of such amounts.

                  13.7 Other Remedies. Except as otherwise provided herein, any

                  13.8 Amendment and Waivers. Any term or provision of this
Agreement may be amended, and the observance of any term of this Agreement may
be waived (either generally or in a particular instance and either retroactively
or prospectively) only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof for default in payment of any amount due
hereunder or default in the performance hereof shall not be deemed to constitute
a waiver of any other default or any succeeding breach or default.

                  13.9 Survival of Agreements. All covenants, agreements,
representations and warranties made herein shall survive the execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby notwithstanding any investigation of the parties hereto.

                  13.10 No Waiver. The failure of any party to enforce any of
the provisions hereof shall not be construed to be a waiver of the right of such
party thereafter to enforce such provisions.

                  13.11 Attorneys' Fees. Should suit be brought to enforce or
interpret any part of this Agreement, the prevailing party shall be entitled to
recover, as an element of the costs of suit and not as damages, reasonable
attorneys' fees to be fixed by the court (including without limitation, costs,
expenses and fees on any appeal). The prevailing party shall be the party
entitled to recover its costs of suit, regardless of whether such suit proceeds
to final judgment. A party not entitled to recover its costs shall not be
entitled to recover attorneys' fees. No sum for attorneys' fees shall be counted
in calculating the amount of a judgment for purposes of determining if a party
is entitled to recover costs or attorneys' fees.

                               AGREEMENT OF MERGER

         THIS AGREEMENT OF MERGER, dated as of _________, 1998 (the "Merger
Agreement"), is made and entered into by and among MC Acquisition Corporation, a
California corporation ("Sub"), MC Informatics, Inc., a California corporation
("MCI" or "Surviving Corporation"), and HealthDesk Corporation, a California

                                    RECITALS

         A. HealthDesk is the beneficial and record owner of all of the
outstanding shares of the capital stock of Sub.

         B. Prior to the execution of this Merger Agreement, the Constituent
Corporations, HealthDesk and certain shareholders of MCI have entered into an
Agreement and Plan of Reorganization dated as of July ___, 1998 (the
"Reorganization Agreement"), providing for certain representations, warranties
and agreements in connection with the transactions contemplated.

         C. The Boards of Directors of the Constituent Corporations deem it
advisable and in the best interests of the Constituent Corporations and in the
best interests of the shareholders of the Constituent Corporations that MCI be
acquired by HealthDesk through a merger of Sub with and into MCI (the "Merger").

         NOW, THEREFORE, the Constituent Corporations hereby agree as follows:

                                    ARTICLE 1

                                   THE MERGER

         Section 2.1

         a. The Merger shall become effective on the date and time ("Effective
Time") that this Agreement of Merger and officers' certificates of each
Constituent Corporation are filed with the Secretary of State of California
pursuant to Section 1103 of the California General Corporation Law ("CGCL").

         b. At the Effective Time, Sub shall be merged with and into MCI and the
separate corporate existence of Sub shall thereupon cease. MCI shall be the
Surviving Corporation in the Merger and the separate corporate existence of MCI,
with all its purposes, objects, rights, privileges, powers, immunities and
franchises, shall continue unaffected and unimpaired by the Merger.

         Section 2.2 The Merger shall have the effects set forth in this
Agreement of Merger and in the CGCL. Without limiting the generality of the
foregoing, from and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises of a public as well as
of a private nature, and be subject to all the restrictions, disabilities and
duties of each of the Constituent Corporations; and all singular rights,
privileges, powers and franchises of each of the Constituent Corporations, and
all property, real, personal and mixed, and all debts due to either of the
Constituent Corporations on whatever account, as well as for stock subscriptions
and all other things in action or belonging to each of the Constituent
Corporations, shall be vested in the Surviving Corporation, and all property,
rights, privileges, powers and franchises, and all and every other interest
shall be thereafter as effectually the property of the Surviving Corporation as
they were of the Constituent Corporations, and the title to any real estate
vested by deed or otherwise, in either of the Constituent Corporations, shall
not revert or be in any way impaired; but all rights of creditors and all liens
upon any property of either of the Constituent Corporations shall be preserved
unimpaired, and all debts, liabilities and duties of the Constituent
Corporations shall thereafter attach to the Surviving Corporation, and may be
enforced against it to the same extent as if such debts and liabilities had been
incurred by it.

                                    ARTICLE 3
                        ARTICLES OF INCORPORATION, BYLAWS

                            THE SURVIVING CORPORATION

         Section 3.1 The Articles of Incorporation of Sub in effect immediately
prior to the Effective Time shall be the Articles of Incorporation of the
Surviving Corporation unless and until amended as provided by law and such
Articles of Incorporation.

         Section 3.2 The Bylaws of Sub in effect immediately prior to the
Effective Time shall be the Bylaws of the Surviving Corporation unless and until
amended or repealed as provided by law, the Articles of Incorporation of the
Surviving Corporation and such Bylaws.

any action on the part of the holder of any shares of MCI Common Stock:

         a. [Each share of Sub Stock which is outstanding immediately prior to
the Effective Time shall be converted into one share of the capital stock of the
Surviving Corporation.]

         b. All outstanding shares of MCI Common Stock shall be converted into
an aggregate of ______________ shares (the "Exchange Ratio") of HealthDesk
common stock, no par value ("HealthDesk Common Stock"). Each holder of MCI
Common Stock exchanged pursuant to the Merger who would otherwise be entitled to
receive a fraction of a share of HealthDesk Common Stock (after taking into
account all of the certificates representing MCI Common Stock delivered by such
holder) shall receive in lieu thereof, cash (without interest) in an amount
equal to such fractional part of a share of HealthDesk Common Stock multiplied
by the average closing price of a share of HealthDesk Common Stock reported on
the Nasdaq SmallCap Market for the five (5) most recent trading days ending on
the trading day immediately prior to the Effective Time.

                                    ARTICLE 5
                            TERMINATION AND AMENDMENT

         Section 5.1 Notwithstanding the approval of this Agreement of Merger by
the shareholders of MCI and Sub, this Agreement of Merger may be terminated at
any time prior to the Effective Time by mutual agreement of the Boards of
Directors of MCI and Sub.

         Section 5.2 Notwithstanding the approval of this Agreement of Merger by
the shareholders of MCI and Sub, this Agreement of Merger shall terminate
forthwith in the event that the Reorganization Agreement shall be terminated as
therein provided at any time prior to the Effective Time.

         Section 5.3 In the event of the termination of this Agreement of Merger
as provided above, this Agreement of Merger shall forthwith become void and
there shall be no liability on the part of MCI or Sub or their respective
officers or directors, except as otherwise provided in the Reorganization
Agreement.

         Section 5.4 This Agreement of Merger may be amended by the parties
hereto at any time before or after approval hereof by the shareholders of either
MCI or Sub but, after any such approval, no amendment shall be made which by law
requires the further approval of the shareholders of either MCI or Sub without
obtaining such further approval. This Agreement of Merger may not be amended
except by an instrument in writing signed on behalf of each of the parties
hereto.

                                  EXHIBIT C

                 NON-COMPETITION AND NON-SOLICITATION AGREEMENT

This Agreement is made as of the Effective Date (as defined below) by and among
HealthDesk Corporation, a California corporation ("HDC"), MC Informatics, Inc.,
a California corporation ("MCI"), and ___________________ , an individual (the
"Employee").

                                    RECITALS

         A. WHEREAS, HDC, MC Acquisition Corporation, a California corporation
and wholly-owned subsidiary of HDC ("Sub"), MCI and certain shareholders
("Shareholders") of MCI entered into an Agreement and Plan of Reorganization as
of July ___, 1998 (the "Merger Agreement"), which provides that Sub merge with
and into MCI, with MCI the surviving corporation (the "Merger"), and HDC will
acquire all of the issued and outstanding shares of capital stock of MCI
together with all of the goodwill of MCI related to the business being conducted
by MCI, as more specifically defined in Appendix I to this Agreement (the
"Business").

         B. WHEREAS, the Employee is a Shareholder and a key employee of MCI,
has been actively involved in the management of MCI and is receiving significant
consideration pursuant to the terms of the Merger Agreement, including a
significant number of shares of HDC capital stock, in exchange for all of the
Employee's shares of MCI.

         C. WHEREAS, in order to preserve the value of the shares of capital
stock being acquired by HDC, the Merger Agreement contemplates, among other
things, that the Employee enter into this Agreement and that the effective date
of this Agreement (the "Effective Date") shall be the Closing Date (as defined
in the Merger Agreement).

         NOW, THEREFORE, in consideration of the mutual promises and
representations made in this Agreement, HDC, MCI and the Employee agree as
follows:

            1. Non-competition.

               (a) Until the earlier of (i) the termination by MCI or HDC of the
Employee's employment with MCI or HDC for any reason other than for Cause (as
defined below) or (ii) the third anniversary of the Effective Date (the
"Restricted Period"), the Employee will not directly or indirectly, as an owner,
partner, stockholder, joint venturer, corporate officer, director, employee,
consultant, principal, trustee or licenser, or in any other similar capacity
whatsoever of or for any person, firm, partnership, company or corporation: (a)
own, manage, operate, sell, control or participate in the ownership, management,
operation, sales or control of, be involved with the development efforts of,
serve as a technical advisor to or supply product to any business that competes
with the Business or (b) solicit, divert or take away, or attempt to solicit,
divert or take away, the business or patronage of any of the clients, customers
or suppliers of MCI or HDC which were contacted, solicited or served by the
Employee while an employee of MCI or HDC. Notwithstanding the foregoing, the
Employee is permitted to own, individually, as

                                       1
<PAGE>

a passive investor up to a one percent (1%) interest in any publicly traded
entity. The restrictions set forth in this Section 1 shall be effective within
all cities and counties of California, all cities, counties and states of the
United States and all other countries in the world.

               (b) If the Employee intentionally or with reckless disregard of
his obligations hereunder violates the provisions of Section 1(a), the Employee
shall continue to be bound by the restrictions set forth in Section 1(a) from
the time such violating activity ceases until a period of three (3) years has
expired without any violation of such provisions.

            2. Non-Solicitation.

               (a) While the Employee is employed by MCI or HDC and for a period
of two (2) years after the termination or cessation of such employment for any
reason, the Employee will not directly or indirectly recruit, solicit or hire
any employee, sales representative or consultant of MCI or HDC, or induce or
attempt to induce such person to terminate his relationship with, or otherwise
cease his relationship with MCI or HDC, as the case may be.

               (b) If the Employee intentionally or with reckless disregard of
his obligations hereunder violates the provisions of Section 2(a), the Employee
shall continue to be bound by the restrictions set forth in Section 2(a) from
the time such violating activity ceases until a period of three (3) years has
expired without any violation of such provisions.

            3. Confidentiality Agreement. Employee shall be subject to the terms
of HDC's standard form of employee confidentiality agreement, a copy of which is
attached hereto as Appendix II.

            4. Cause. For the purposes of this Agreement, "Cause" shall mean any
material misconduct by the Employee (including, without limitation,
disparagement that adversely affects the reputation of MCI or HDC, conviction of
a crime involving moral turpitude, substance abuse, misappropriation of funds of
MCI, HDC, or any of their affiliates, or dishonesty related to his employment by
MCI or HDC) or material failure to perform the Employee's responsibilities in
the best interests of MCI or HDC, including, without limitation, breach by the
Employee of any material provision of any employment, nondisclosure,
non-competition or other similar agreement between the Employee and MCI and/or
HDC or failure of the Employee to perform any reasonably assigned duties after
written notice from MCI and/or HDC of, and a reasonable opportunity to cure,
such failure.

            5. Condition of Merger; Consideration. The Employee agrees that the
covenants provided for in Sections 1 and 2 including the term of the Restricted
Period and the geographical area encompassed in such covenants, are necessary
and reasonable in order to protect HDC and MCI in the conduct of the Business
and the utilization of MCI's assets, tangible and intangible, including
goodwill, and to preserve and protect the tangible and intangible assets of MCI,
including MCI's goodwill, and the customers and trade secrets of which the
Employee has and will have knowledge, and in consideration for HDC entering into
and performing under the Merger Agreement. All parties agree that the execution,
delivery and performance of this Agreement is in consideration of and a
condition to the consummation of the Merger and the

                                       2
<PAGE>

parties do not ascribe and cannot ascribe a separate consideration or value to
the covenants provided in this Agreement.

            6. Dispute Resolution. In the event of any dispute or claim relating
to or arising out of the Employee's employment with MCI or HDC pursuant to this
Agreement (including, but not limited to, any claims of breach of contract,
wrongful termination or age, sex, race or other discrimination), the Employee,
MCI and HDC agree that all such disputes shall be fully and finally resolved by
binding arbitration conducted by the American Arbitration Association in San
Francisco, California. The Employee acknowledges that by accepting this
arbitration provision he is waiving any right to a jury trial in the event of
such dispute, provided, however, that this arbitration provision shall not apply
to any disputes or claims relating to or arising out of the misuse or
misappropriation of MCI's or HDC's trade secrets or proprietary information.

            7. Attorneys' Fees. The prevailing party shall be entitled to
recover from losing party its attorneys' fees and costs incurred in action
brought to enforce any right arising out of this Agreement.

            8. Miscellaneous.

               (a) No Conflict. The Employee represents that the execution and
performance by him of this Agreement does not and will not conflict with or
breach the terms of any other agreement by which the Employee is bound.

               (b) Not Employment Contract. The Employee acknowledges that this
Agreement does not constitute a contract of employment and does not imply that
MCI or HDC will continue his employment for any period of time.

               (c) Interpretation. The covenants contained in the preceding
paragraphs shall be construed as a series of separate covenants, one for each of
the counties in each of the states of the United States of America, one for each
province of Canada, and one for any other geographic area where the Business is
currently carried on by MCI or HDC. Except for geographic coverage, each such
separate covenant shall be identical in terms to the covenant contained in the
preceding paragraphs. If, in any judicial proceeding, a court refuses to enforce
any of such separate covenants (or any part thereof), then such unenforceable
covenant (or such part) shall be eliminated from this Agreement to the extent
necessary to permit the remaining separate covenants (or portions thereof) to be
enforced. In the event that the provisions of Sections 1 or 2 are deemed to
exceed the time, geographic or scope limitations permitted by applicable law,
then such provisions shall be reformed to the maximum time, geographic or scope
limitations, as the case may be, permitted by applicable laws.

               (d) Severability. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement.

                                       3
<PAGE>

               (e) Waiver of Rights. No delay or omission by MCI or HDC in
exercising any right under this Agreement will operate as a waiver of that or
any other right. A waiver or consent given by MCI or HDC on any one occasion is
effective only in that instance and will not be construed as a bar to or waiver
of any right on any other occasion.

               (f) Equitable Remedies. The restrictions contained in this
Agreement are necessary for the protection of the business and goodwill of MCI
and HDC and are considered by the Employee to be reasonable for such purpose.
The Employee acknowledges that his services are needed by virtue of the Merger.
The Employee agrees that any breach of this Agreement is likely to cause MCI and
HDC substantial and irreparable damage and therefore, in the event of any such
breach, the Employee agrees that MCI and HDC, in addition to such other remedies
which may be available, shall be entitled to specific performance and other
injunctive relief.

               (g) Assignability. HDC and MCI may assign this Agreement to any
other corporation or entity which acquires (whether by purchase, merger,
consolidation or otherwise) all or substantially all of the business and/or
assets of MCI and/or HDC. Neither this Agreement nor any of the rights or
obligations of the Employee arising under this Agreement may be assigned or
transferred without HDC's or MCI's prior written consent.

               (h) Notices. Any notice provided for or permitted under this
Agreement will be treated as having been given (a) when delivered personally,
(b) when sent by confirmed telex or telecopy, (c) on the next business day when
sent by commercial overnight courier with written verification of receipt, or
(d) five days (5) after being mailed postage prepaid by certified or registered
mail, return receipt requested, to the party to be notified, at the address set
forth below, or at such other place of which the other party has been notified
in accordance with the provisions of this Section.

         5. Termination.

            5.1 Termination Events. The employment hereunder will terminate upon

                (a) Employee dies;

                (b) the Company, by written notice to Employee or his personal
representative, discharges Employee due to the inability to perform the duties
assigned to him hereunder for a continuous period exceeding ninety (90) days by
reason of injury, physical or mental illness or other disability, which
condition has been certified by a physician; provided, however, that prior to
discharging Employee due to such disability, the Company shall give a written
statement of findings to Employee or his personal representative setting forth
specifically the nature of the disability and the resulting performance
failures, and Employee shall have a period of ten (10) days thereafter to
respond in writing to the Board of Directors' findings;

                (c) Employee is discharged by the Board of Directors of the
Company for cause. As used in this Agreement, the term "cause" shall mean:

                    (i) Employee's conviction of (or pleading guilty or nolo
contenders to) a felony or any misdemeanor involving dishonesty or moral
turpitude; provided, however, that prior to discharging Employee for cause, the
Company shall give a written statement of findings to Employee setting forth
specifically the grounds on which cause is based, and Employee shall have a
period of ten (10) days thereafter to respond in writing to the Board of
Directors' findings;

                    (ii) the willful and continued failure of Employee to
substantially perform his duties with the Company (other than any such failure
resulting from illness or disability) after a written demand for substantial
performance is requested by the Company's Board of Directors, which specifically
identifies the manner in which it is claimed Employee has not substantially
performed his duties, or (b) Employee is willfully engaged in misconduct which
has, or can reasonably be expected to have, a direct and material adverse
monetary effect on the Company. For purposes of this Section no act or failure
to act on Employee's part shall be considered "willful" if done, or omitted to
be done, by Employee in good faith and with reasonable belief that Employee's
action or omission was in the best interest of the Company.

No termination shall be effected for cause unless Employee has been provided
with specific information as to the acts or omissions which form the basis of
the allegation of cause, and Employee has had an opportunity to be heard, with
counsel if he so desired, before the Board of Directors and such Board
determines, by majority vote, in good faith that Employee was guilty of conduct
constituting "cause" as herein defined, specifying the particulars thereof in
detail.

                (d) Employee is discharged by the Board of Directors of the
Company without cause, which the Company may do at any time, with at least ten
(10) days advance written notice;

                                       3
<PAGE>

                (e) Employee voluntarily terminates his employment due to either
(i) a default by the Company in the performance of any of its obligations
hereunder, or (ii) an Adverse Change in Duties (as defined below), which default
or Adverse Change in Duties remains unremedied by the Company for a period of
ten (10) days following its receipt of written notice thereof from Employee; or

                (f) Employee voluntarily terminates his employment for any
reason other than the Company's default or an Adverse Change in Duties, which
Employee may do at any time with at least thirty (30) days advance notice.

         As used herein, "Adverse Change in Duties" means an action or series of
actions taken by the Company, without Employee's prior written consent, which
results in:

         (1) A change in Employee's reporting responsibilities, titles, job
responsibilities or offices which results in a material diminution of his
status, control or authority; or

         (2) The assignment to Employee of any positions, duties or
responsibilities which are materially inconsistent with Employee's positions,
duties and responsibilities or status with the Company; or

         (3) A requirement by the Company that Employee be based or perform his
duties anywhere other than (i) at the Company's corporate office location on the
date of this Agreement, or (ii) if the Company's corporate office location is
moved after the date of this Agreement, at a new location that is no more than
sixty (60) miles from such prior location; or

         (4) A failure by the Company to provide for Employee's participation in
any current or future benefits or plans at a level or to an extent commensurate
with (i.e., at a value of at least seventy percent (70%)) that of other top
executives (i.e., vice presidents or above) of the Company.

            5.2 Effects of Termination.

                (a) Upon termination of Employee's employment hereunder for any
reason, the Company will promptly pay Employee all compensation owed to Employee
and unpaid through the date of termination (including, without limitation,
salary and employee expenses reimbursements).

                (b) In addition, if the employment is terminated under Sections
5.1(b), (d) or (e), the Company shall also pay Employee a severance amount equal
to one-half of the then applicable annual salary, excluding bonus, equally
divided over a six month period.

                (c) Upon termination of Employee's employment, the Employee will
return all warrants granted to Employee.

                                       4

         Employee acknowledges that monetary damages may not be sufficient to
compensate the Company for any economic loss which may be incurred by reason of
breach of the foregoing restrictive covenants. Accordingly, in the event of any
such breach, the Company shall, in addition to any remedies available to the
Company at law, be entitled to obtain equitable relief in the form of an
injunction precluding Employee from continuing to engage in such breach.

         If any restriction set forth in this paragraph is held to be
unreasonable, then Employee and the Company agree, and hereby submit, to the
reduction and limitation of such prohibition to such area or period as shall be
reasonable.

may be amended, and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively) only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof for default in payment of any amount due
hereunder or default in the performance hereof shall not be deemed to constitute
a waiver of any other default or any succeeding breach or default.

____________, 1998



HealthDesk Corporation
2560 Ninth Street, Suite 220
Berkeley, CA  94710

Ladies and Gentlemen:

The undersigned understands that pursuant to an Agreement and Plan of
Reorganization (the "Merger Agreement") dated July ___, 1998, by and among
HealthDesk Corporation, a California corporation ("HDC"), MC Acquisition
Corporation, a California corporation and a wholly-owned subsidiary of HDC
("Sub"), MC Informatics, Inc., a California corporation ("MCI") and certain
shareholders of MCI, Sub shall be merged with and into MCI, with MCI the
surviving corporation (the "Merger").

Pursuant to the Merger Agreement, and in consideration of the terms of the
Merger and other good and valuable consideration, receipt of which is hereby
acknowledged, the undersigned hereby agrees, from the date hereof until and
including twelve (12) months after the date of the closing of the Merger, not to
offer to sell, contract to sell or otherwise sell, dispose of, loan, pledge or
grant any rights with respect to (collectively, a "Disposition") any shares of
capital stock of HDC (the "HDC Capital Stock"), any options or warrants to
purchase any shares of HDC Capital Stock or any securities convertible into or
exchangeable for shares of HDC Capital Stock (collectively, "Securities"), now
owned or hereafter acquired directly by the undersigned or with respect to which
the undersigned has or hereafter acquires the power of disposition, otherwise
than (i) as a bona fide gift or gifts, provided the donee or donees thereof
agree to be bound by this Lock-Up Agreement, or (ii) with the prior written
consent of HDC. The foregoing restriction is expressly agreed to preclude the
holder of the Securities from engaging in any hedging or other transaction which
is designed to or reasonably expected to lead to or result in a Disposition of
Securities during the Lock-Up Period even if such Securities would be disposed
of by someone other than the undersigned. Such prohibited hedging or other
transactions would include, without limitation, any short sale (whether or not
against the box) or any purchase, sale or grant of any right (including without
limitation any put or call option) with respect to any Securities or with
respect to any security (other than a broad-based market basket or index) that
includes, relates to or derives any significant part of its value from the
Securities.

Furthermore, the undersigned hereby agrees and consents to the entry of stop
transfer instructions with HDC's transfer agent against the transfer of the
Securities held by the undersigned except in compliance with this Lock-Up
Agreement.


                                       Very truly yours,

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT is made as of the ____ day of
_______, 1998, by and between HealthDesk Corporation, a California corporation
(the "Company"), and each other person or entity executing this Agreement.

                                    RECITALS

         WHEREAS, the Company has issued shares of its common stock, no par
value (the "Common Stock") to certain investors (the "Investors") pursuant to
the terms of the Agreement and Plan of Reorganization by and among the Company,
MC Acquisition Corporation, a California corporation and a wholly-owned
subsidiary of the Company, MC Informatics, Inc., a California corporation
("MCI") and certain shareholders of MCI (the "Merger");

         WHEREAS, the Company and the Investors desire to provide for certain
arrangements with respect to the registration of shares of Common Stock of the
Company under the Securities Act of 1933, as amended (the "Securities Act"),
held by the Investors as provided in this Agreement;

         NOW, THEREFORE, in consideration of the mutual promises and agreements
contained herein and for other good and valuable consideration the receipt and
sufficiency of which are hereby acknowledged, the Company and the Investors
hereby agree as follows:

                                    AGREEMENT

         1. Registration Rights. The Company covenants and agrees as follows:

            1.1 Definitions. For purposes of this Paragraph 1:

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

                (b) The term "Registrable Securities" means (1) the shares of
Common Stock issued to the Investors in connection with the Merger and (2) any
Common Stock of the Company issued as (or issuable upon the conversion or
exercise of any warrant, right or other security which is issued as) a dividend
or other distribution with respect to, or in exchange for or in replacement of,
such Common Stock, excluding in all cases, however, any Registrable Securities
sold by a person in a transaction in which his rights under this Section 1 are
not assigned or pursuant to an effective registration statement or to the public
pursuant to an exemption from registration requirements under the Securities
Act;

                                       1
<PAGE>

                (c) The number of shares of "Registrable Securities then
outstanding" shall be determined by the number of shares of Common Stock
outstanding which are Registrable Securities; and

                (d) The term "Holder" means any person owning or having the
right to acquire Registrable Securities or any assignee thereof in accordance
with Section 1.12 hereof.

            1.2 Request for Registration.

                (a) If the Company shall receive at any time after the date of
this Agreement and prior to the one year anniversary of this Agreement, a
written request from the Holders of more than fifty percent (50%) of the
Registrable Securities then outstanding that the Company file a registration
statement under the Securities Act covering the registration of at least fifty
percent (50%) of the Registrable Securities then outstanding, then the Company
shall promptly give written notice of such request to all Holders and shall,
subject to the limitations of subsection 1.2(b), effect as soon as practicable
the registration under the Securities Act of all Registrable Securities which
the Holders request to be registered within thirty (30) days of the mailing of
such notice by the Company in accordance with Section 2.5.

                (b) If the Holders initiating the registration request hereunder
("Initiating Holders") intend to distribute the Registrable Securities covered
by their request by means of an underwriting, they shall so advise the Company
as a part of their request made pursuant to this Section 1.2 and the Company
shall include such information in the written notice referred to in subsection
1.2(a). The underwriter will be selected by a majority in interest of the
Initiating Holders and approved by the Company, which approval shall not
unreasonably be withheld. In such event, the right of any Holder to include his
Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
(together with the Company as provided in subsection 1.4(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by a majority in interest of the Initiating
Holders. Notwithstanding any other provision of this Section 1.2, if the
underwriter advises the Initiating Holders in writing that marketing factors
require a limitation of the number of shares to be underwritten, then the
Initiating Holder shall so advise all Holders of Registrable Securities that may
be included in the underwriting that such number of Registrable Securities to be
included shall be allocated among all such Holders thereof, including the
Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each Holder; provided, however,
that the number of shares of Registrable Securities to be included in such
underwriting shall not be reduced unless all other securities are first entirely
excluded from the underwriting.

                (c) The Company is obligated to effect only one (1) such
registration pursuant to this Section 1.2.

                                       2
<PAGE>

                (d) Notwithstanding the foregoing, if the Company shall furnish
to Holders requesting a registration statement pursuant to this Section 1.2 a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company and its shareholders for such registration statement
to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer taking action
with respect to such filing for a period of not more than sixty (60) days after
receipt of the request of the Initiating Holders; provided, however, that the
Company may not utilize this right more than once in any twelve month period.

            1.3 Company Registration.

                (a) If (but without any obligation to do so) at any time after
_______, 1999, and prior to _______, 2000, the Company proposes to register
(including for this purpose a registration effected by the Company for
shareholders other than the Holders) any of its stock or other securities under
the Securities Act in connection with the public offering of such securities
solely for cash (other than a registration relating solely to the sale of
securities to participants in a Company stock plan, or a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within thirty (30) days after mailing of such notice by the Company
in accordance with Section 2.5, the Company shall, subject to the provisions of
Section 1.8, cause to be registered under the Securities Act all of the
Registrable Securities that each such Holder has requested to be registered.

                (b) The Company is obligated to effect only two (2) such
registrations pursuant to this Section 1.3.

            1.4 Obligations of the Company. Whenever required under this
Paragraph 1 to effect the registration of any Registrable Securities, the
Company shall, as expeditiously as reasonably possible:

                (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective for up to one hundred twenty (120) days for the
purpose of selling all stock or securities registered with the SEC.

                (b) Prepare and file with the SEC 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.

                                       3
<PAGE>

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

                (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

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

                (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the 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 in the light of the circumstances then
existing.

                (g) Furnish, at the request of any Holder requesting
registration of Registrable Securities pursuant to this Paragraph 1, on the date
that such Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Paragraph 1 if such securities
are being sold through underwriters, or, if such securities are not being sold
through underwriters on the date that the registration statement with respect to
such securities becomes effective, (i) an opinion dated such date of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a "cold comfort" letter dated
such date from the independent certified public accountants of the Company, in
form and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering, addressed to the
underwriters, if any, and to the Holders requesting registration of Registrable
Securities.

            1.5 Furnish Information.

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

                                       4
<PAGE>

                (b) The Company shall have no obligation with respect to any
registration requested pursuant to Section 1.2 if, due to the operation of
subsection 1.5(a), the number of shares or the anticipated aggregate offering
price of the Registrable Securities to be included in the registration does not
equal or exceed the number of shares or the anticipated aggregate offering price
required to originally trigger the Company's obligation to initiate such
registration as specified in subsection 1.2(a).

            1.6 Expenses of Demand Registration. All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings, or qualifications pursuant to Section 1.2, including
without limitation all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for the Company, and the
reasonable fees and disbursements of one counsel for the selling Holders shall
be borne by the Company; provided, however, that the Company shall not be
required to pay for any expenses of any registration proceeding begun pursuant
to Section 1.2 if the registration request is subsequently withdrawn at the
request of the Holders of a majority of the Registrable Securities to be
registered (in which case all Participating Holders shall bear such expenses),
unless the Holders of a majority of the Registrable Securities agree to forfeit
their right to demand registration pursuant to Section 1.2; provided further,
however, that if at the time of such withdrawal, the Holders have learned of a
material adverse change in the condition, business, or prospects of the Company
from that known to the Holders at the time of their request and have withdrawn
the request with reasonable promptness following disclosure by the Company of
such material adverse change, then the Holders shall not be required to pay any
of such expenses and shall retain their rights pursuant to Section 1.2. Fees and
disbursements of counsel and accountants for the selling Holders and any other
expenses incurred by the selling Holders not expressly included above shall be
borne by the selling Holders.

            1.7 Expenses of Company Registration. The Company shall bear and pay
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to all registrations
pursuant to Section 1.3 for each Holder (which right may be assigned as provided
in Section 1.12), including, without limitation, all registration, filing, and
qualification fees, printers and accounting fees relating or apportionable
thereto and the fees and disbursements of one counsel for the selling Holders
selected by them, but excluding underwriting discounts and commissions relating
to Registrable Securities.

            1.8 Underwriting Requirements. In connection with any offering
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters determine in their sole discretion is
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters determine in

                                       5
<PAGE>

their sole discretion will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling shareholders
according to the total amount of securities entitled to be included therein
owned by each selling shareholder or in such other proportions as shall mutually
be agreed to by such selling shareholders) but in no event shall (i) the amount
of securities, including Registrable Securities and all other securities the
holders of which have similar rights, of the selling shareholders included in
the offering be reduced below thirty percent (30%) of the total amount of
securities included in such offering, or (ii) notwithstanding (i) above, any
shares being sold by a shareholder exercising a demand registration right
similar to that granted in Section 1.2 be excluded from such offering. For
purposes of the preceding parenthetical concerning apportionment of any selling
shareholder which is a holder of Registrable Securities and which is a
partnership or corporation, the partners, retired partners and shareholders of
such holder, or the estates and family members of any such partners and retired
partners and any trusts for the benefit of any of the foregoing persons shall be
deemed to be a single "selling shareholder," and any pro-rata reduction with
respect to such "selling shareholder" shall be based upon the aggregate amount
of shares carrying registration rights owned by all entities and individuals
included in such "selling shareholder," as defined in this sentence.

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

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

                 (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Securities
Act) for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act or the Securities and
Exchange Act of 1934, as amended (the "1934 Act"), against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Securities Act, or the 1934 Act or other federal or state law, insofar
as such losses, claims, damages, or liabilities (or actions in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations (collectively, a "Violation"): (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the 1934 Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
or the 1934 Act or any state securities law; and the Company will pay to each
such Holder, underwriter or controlling person, as incurred, any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection 1.10(a) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of the Company
(which consent shall not be

                                       6
<PAGE>

unreasonably withheld), nor shall the Company be liable in any such case for any
such loss, claim, damage, liability, or action to the extent that it arises out
of or is based upon a Violation which occurs in reliance upon and in conformity
with written information furnished expressly for use in connection with such
registration by any such Holder, underwriter or controlling person.

                 (b) To the extent permitted by law, each selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter,
any other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Securities Act, or the 1934 Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon and in conformity
with written information furnished by such Holder for use in connection with
such registration; and each such Holder will pay, as incurred, any legal or
other expenses reasonably incurred by any person intended to be indemnified
pursuant to this subsection 1.10(b), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this subsection 1.10(b) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability
or action if such settlement is effected without the consent of the Holder,
which consent shall not be unreasonably withheld; provided that in no event
shall any indemnity under this subsection 1.10(b) exceed the gross proceeds from
the offering received by such Holder.

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

                                       7
<PAGE>

                 (d) If the indemnification provided for in this Section 1.10 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expenses 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 it appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

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

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

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

                 (a) make and keep public information available, as those terms
are understood and defined in SEC Rule 144, at all times;

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

                 (c) furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144,
the Securities Act and the 1934 Act, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration.

            1.12 Assignment of Registration Rights. The rights to cause the
Company to register Registrable Securities pursuant to this Paragraph 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities provided the Company is, within a reasonable time
after such transfer, furnished with written notice of the

                                       8
<PAGE>

name and address of such transferee or assignee and the securities with respect
to which such registration rights are being assigned; and provided, further,
that such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act.

            1.13 Limitation on Subsequent Registration Rights. From and after
the date of this Agreement, the Company shall not, without the prior written
consent of the Holders of a majority of the outstanding Registrable Securities,
enter into any agreement with any holder or prospective holder of any securities
of the Company which would allow such holder or prospective holder to include
such securities in any registration filed under Section 1.2 hereof, unless under
the terms of such agreement, such holder or prospective holder may include such
securities in any such registration only to the extent that the inclusion of his

             generally accepted accounting principles ("GAAP") consistently

             required to be reflected or disclosed in a balance sheet (or the
             notes thereto) prepared in accordance with GAAP that were not fully

         6.4 Taxes. Seller has filed or caused to be filed all federal, state
and local tax returns and reports that are or were required to be filed by or
with respect to Seller, pursuant to applicable law. All such returns were
correct and complete in all respects. Seller has paid, or has provided for the
payment of, all taxes that have or may have become due pursuant to those tax
returns or otherwise, or pursuant to any assessment received by Seller, except
such taxes, if any, as are listed in Schedule 6.4 and are being contested in
good faith and as to which adequate reserves (determined in accordance with
GAAP) have been provided in the Financial Statements. Except as set forth in
Schedule 6.4, no audit of any tax return of Seller is in progress or, to
Seller's knowledge, threatened; no director, officer or employee of Seller
responsible for tax matters expects any governmental authority to assess any
additional taxes for any period for which tax returns have been filed; and no
waiver or agreement by Seller is in force for the extension of time for the
assessment or payment of any tax. To Seller's knowledge, no claim has ever been
made by any governmental authority in a jurisdiction where Seller does not file
tax returns that it is or may be subject to taxation by that jurisdiction.

                  Seller has withheld and paid or collected and remitted all
taxes required to have been withheld and paid in connection with amounts paid or
owing to any employee, independent contractor, supplier, vendor, creditor,
stockholder or other third party. There is no dispute or claim concerning any
tax liability of Seller, (i) claimed or raised by any governmental authority in
writing or (ii) as to which Seller or the directors and officers of Seller has
knowledge. As of the date hereof, there have been no, and Seller has no
knowledge of any, threatened or intended reappraisals by any governmental
authority with respect to the value of the Assets.

         6.5 Real Property. Seller does not own any real property.

         6.6 Inventories. The Inventories consist of items of a quality and
quantity useable, salable or rentable in the ordinary course of business by
Seller, except for obsolete and slow-moving items and items below standard
quality, all of which have been written down on the books of Seller to net
realizable market value or have been provided for by adequate reserves. All
items included in the Inventories are the property of Seller, except for sales
made in the ordinary course of business; for each of these sales either the
purchaser has made full payment or the purchaser's liability to make payment is
reflected in the books of Seller. No items included in the Inventories have been
pledged as collateral or are held by Seller on consignment from the others. All
the Inventories are free of defects and, to the extent that they consist of
finished or semi-finished goods, also comply with the specifications submitted
by the purchasers thereof.

         6.7 Intellectual Property. Schedule 6.7 lists all of the Intellectual
Property owned or used by Seller in connection with the Business (other than
shrink wrap software generally available to the public). No person (other than
Seller) owns any Intellectual Property, the use of which is necessary or
contemplated in connection with the performance of any contract to which Seller
is a party, except manufacturer's trademarks and trade names on goods sold in
Seller's Business. Except as set forth in Schedule 6.7 or 6.15, there have not
been any administrative, judicial arbitration, or other adversary proceedings
concerning the Intellectual Property. Seller does not violate or infringe on any
intellectual property or personal right of any person, firm or corporation, and
Seller has not infringed and is not now infringing on any intellectual property
or other right belonging to any person, firm or corporation. Except as set forth
in Schedule 6.7 or Schedule 1.1, Seller is not a party to any license, agreement
or arrangement, whether as licensee, licensor or otherwise, with respect to any
Intellectual Property.

         6.8 Trade Secrets. Seller has taken all reasonable security measures to
protect the secrecy, confidentiality and value of all trade secrets used by
Seller (or owned by Seller and useful in) the operation of the Business. Any of
its employees and any other persons who, either alone or in concert with others,
developed, invented, discovered, derived, programmed or designed these secrets,
or who have knowledge of or access to information relating to them, have been
put on notice and have entered into appropriate agreements that these secrets
are proprietary to Seller and are not to be divulged or misused. All these trade
secrets are presently valid and protectible, and are not part of the public
knowledge or literature, nor to Seller's knowledge have they been used, divulged
or appropriated for the benefit of any past or present employees or other
persons, or to the detriment of Seller.

         6.9 Title to Assets. Seller has good and marketable title to all the
Assets and its interests in the Assets, whether real, personal, mixed, tangible
or intangible, which constitute all the Assets and interests in Assets that are
used in the Business. All the Assets are free and clear of mortgages, liens,
pledges, charges, encumbrances, equities, claims, easements, rights of way,
covenants, conditions or restrictions, except for (i) those disclosed in
Schedule 6.9; (ii) the lien of current taxes not yet due and payable; and (iii)
possible minor matters that, in the aggregate, are not substantial in amount and
do not materially detract from or interfere with the present or intended use of
any of these assets, nor materially impair business operations. All the Assets
are in good operating condition and repair, ordinary wear and tear excepted.
Seller is in possession of all premises leased to it from others. Neither any
officer, director or employee of Seller, nor any spouse, child or other relative
of any of these persons, owns, or has any interest, directly or indirectly, in
any of the real or personal property owned by or leased to Seller or any
Intellectual Property or trade secrets licensed by Seller.

         6.10 Customers and Sales. Schedule 6.10 to this Agreement is a correct
and current list of all customers of Seller. Except as indicated in Schedule
6.10, Seller has no information and is not aware of any facts indicating that
any of these customers intend to cease doing business with Seller or materially
alter the amount of the business that they are presently doing with Seller.

         6.11 Existing Employment Contracts. Schedule 6.11 to this Agreement is
a list of all employment contracts and collective bargaining agreements, and all
pension, bonus, profit-sharing, stock option or other agreements or arrangements
providing for employee remuneration or benefits to which Seller is a party or by
which Seller is bound. All of these contracts and arrangements are in full force
and effect, and neither Seller nor any other party is in default under them.
There have been no claims of defaults and, to Seller's knowledge, there are no
facts or conditions which if continued, or on notice, will result in a default
under these contracts or arrangements. There is no pending or, to Seller's
knowledge, threatened labor dispute, strike or work stoppage affecting the
Business.

         6.12 Insurance Policies. Seller has maintained and now maintains (i)
insurance on all the Assets of a type customarily insured, covering property
damage and loss of income by fire or other casualty, and (ii) adequate insurance
protection against all liabilities, claims and risks against which it is
customary to insure, including without limitation earthquakes as to properties
located in California.

         6.13 Other Contracts. Except as set forth in Schedule 1.1 or Schedule
4, Seller is not a party to, nor are the Assets bound by, any license or service
agreement, any output or requirements agreement, any agreement not entered into
in the ordinary course of business, any indenture, mortgage, deed of trust,
lease or any other agreement that is unusual in nature, duration or amount
(including without limitation any agreement requiring the performance by Seller
of any obligation for a period of time extending beyond one year from the
Closing Date or calling for consideration of more than $25,000 or requiring
purchases at prices in excess of, or sales at prices lower than, prevailing
market prices). All contracts which will be assigned to or assumed by Buyer
under this Agreement are valid and binding upon the parties thereto. There is no
default or event that, with notice or lapse of time or both, would constitute a
default by any party to any of the agreements listed in Schedule 1.1 or Schedule
4. Seller has not received notice that any party to any of the agreements listed
in Schedule 1.1 or Schedule 4 intends to cancel or terminate any of these
agreements or to exercise or not exercise any options under any of these
agreements.

         6.14 Compliance with Laws. Seller has complied with, and is not in
violation of, applicable federal, state or local statutes, laws and regulations
(including without limitation any applicable environmental, health, building,
zoning or other law, ordinance or regulation) affecting its properties or the
operation of the Business. Seller is in possession of all permits, licenses,
franchises, consents or authorizations issued by and in compliance with all
registrations and filings required by any governmental authority in connection
with the Business or the Assets. All of such permits, licenses, franchises and
authorizations are valid and in full force and effect.

         6.15 Litigation. Except as set forth in Schedule 6.15, there is no
suit, action, arbitration or legal, administrative or other proceeding, or
governmental investigation, pending or, to Seller's knowledge, threatened
against or affecting Seller, or any of its business, assets or financial
condition. The matters set forth in Schedule 6.15, if decided adversely to
Seller, will not result in a material adverse change in the business, assets or
financial condition of Seller. Seller has furnished or made available to Buyer
copies of all relevant court papers and other documents relating to the matters
set forth in Schedule 6.15. Seller is not in default with respect to any order,
writ, injunction or decree of any federal, state, local or foreign court,
department, agency or instrumentality. Except as set forth in Schedule 6.15,
Seller is not presently engaged in any legal action to recover moneys due to it
or damages sustained by it.

with the Excluded Assets, constitute all of the assets required for Buyer to
conduct the Business as it is presently conducted.

         6.17 Agreement Will Not Cause Breach or Violation. Neither the entry
into this Agreement nor the consummation of the transactions contemplated hereby
will result in or constitute any of the following: (i) a breach of any term or
provision of this Agreement; (ii) a default or an event that, with notice or
lapse of time or both, would be a default, breach or violation of the

capacity and authority to enter into, and perform its obligations under, this
Agreement, and, except as set forth on Schedule 6.18, no approvals or consents
of any persons other than the stockholders of Seller are necessary in connection
with it. The execution and delivery of this Agreement and the consummation of
this transaction by Seller have been, or prior to the Closing will have been,
duly authorized by all necessary corporate action of Seller (including any
necessary action by Seller's stockholders). This Agreement constitutes a legal,
valid and binding obligation of Seller enforceable in accordance with its terms
except as limited by bankruptcy and insolvency laws and by other laws affecting
the rights of creditors generally.

         6.19 Interest in Customers, Suppliers and Competitors. Except as set
forth in Schedule 6.19, neither Seller nor any officer or director of Seller,
nor, to Seller's knowledge, any spouse or child of any of them, has any direct

ARTICLE 11. OBLIGATIONS OF THE PARTIES AFTER THE CLOSING

         11.1 Preservation of Goodwill. Following the Closing, Seller will
restrict its activities so that Buyer's reasonable expectations with respect to
the goodwill, business reputation, employee relations and prospects connected
with the Assets will not be materially impaired. In furtherance but not in
limitation of this general obligation, Seller agrees that, for a period of three
years following the Closing Date, or as long as Buyer or its heirs, assigns or
successors in interest carry on a like business in the counties or areas
specified, whichever is shorter:

             (a)  Seller will not engage in any business or activity which is
                  substantially the same as, or represents an outgrowth of, any
                  business or activity presently conducted by Seller if such
                  business or activity extends to any of the geographic areas
                  set forth in Schedule 11.1 in which Seller has heretofore
                  engaged in business or otherwise established its goodwill,
                  business reputation, or any customer relations.

                  The parties intend that the covenant contained in the
                  preceding portion of this Section 11.1(a) shall be construed
                  as a series of separate covenants, one for each geographic
                  area specified in Schedule 11.1. Except for geographic
                  coverage, each separate covenant shall be deemed identical in
                  terms to the covenant contained in the preceding paragraph.
                  If, in any judicial proceeding, a court shall refuse to
                  enforce any of the separate covenants deemed included in this
                  Section, then this unenforceable covenant shall be deemed
                  eliminated from these provisions for the purpose of those
                  proceedings to the extent necessary to permit the remaining
                  separate covenants to be enforced.

             (b)  Seller will not disclose to any person, or use for its own
                  benefit, any price lists, pricing data, customer lists or
                  similar matters possessed by them relating to the Assets or
                  the Business transferred to Buyer unless it first clearly
                  demonstrates to Buyer that such matters are, at the time of
                  the proposed disclosure or use, of common knowledge within the
                  trade.

         11.2 Change of Name. Seller agrees that after the Closing Date it shall
not use or employ in any manner, directly or indirectly, the name "HealthDesk",
or any variation thereof, and that it will take and cause to be taken all
necessary action by Seller's board of directors, stockholders and any other
persons in order to make this change in Seller's name effective on or before the
Closing Date.

         11.3 Access to Records. From and after the Closing, Seller shall allow
Buyer, and its counsel, accountants and other representatives, such access to
records which after the Closing are in the custody or control of Seller as Buyer
reasonably requires in order to comply with its obligations under the law or
under contracts assumed by Buyer pursuant to this Agreement.

         11.4 Nonsolicitation of Employees. Seller shall not, prior to the third
anniversary of the Closing, solicit any employee of Buyer or Parent or of any
direct or indirect subsidiary of Buyer or Parent to leave such employment if
such employee was at any time between the date hereof and the Closing an
employee of Seller.



                                       20
<PAGE>

         11.5 Further Assurances. At any time after the Closing Date, each of
Seller, Buyer and Parent shall execute, acknowledge and deliver any further
deeds, assignments, conveyances and other assurances, documents and instruments
of transfer, reasonably requested by any other party, and shall take any other
action consistent with the terms of this Agreement that may reasonably be
requested by such other party in furtherance of the transactions contemplated by
this Agreement.

         11.6 Termination of IAC Contract. Buyer agrees to pay to Information
Access Company ("IAC"), on or about November 15, 1998 or the Closing Date,
whichever is later, the sum of $65,000 in connection with the termination of
that certain Online Vendor License Agreement, dated August 12, 1996, between IAC
and Seller, as amended (the "IAC Agreement"); provided, however, that IAC agrees
to continue its obligations under the IAC Agreement, and Buyer shall be entitled
to all of Seller's rights under the IAC Agreement, until February 28, 1999.

ARTICLE 12. INDEMNIFICATION

         12.1. Indemnification by Seller. Seller shall defend, indemnify and
hold harmless each of Buyer, Parent and their respective employees, successors
and assigns (Buyer, Parent and such persons, collectively, "Buyer's Indemnified
Persons"), and shall reimburse Buyer's Indemnified Persons, for, from and
against each and every demand, claim, loss (which shall include any diminution
in value), liability, judgment, damage, cost and expense (including, without
limitation, interest, penalties, costs of preparation and investigation, and the
reasonable fees, disbursements and expenses of attorneys, accountants and other
professional advisors) (collectively, "Losses") imposed on or incurred by
Buyer's Indemnified Persons, directly or indirectly, relating to, resulting from
or arising out of: (a) any inaccuracy in any representation or warranty, or any
breach or nonfulfillment of any covenant, agreement or other obligation of the
Seller under this Agreement, the schedules hereto or any certificate or other
document delivered or to be delivered pursuant hereto; and (b) any obligation of
Seller relating to the Assets and any other matter arising out of or related to
the operation of the Business arising prior to or on the Closing Date. The
maximum liability of Seller under this Section 12.1 shall be limited to the
Purchase Price.

         12.2. Indemnification by Buyer and Parent. Buyer and Parent shall
defend, indemnify and hold harmless the Seller, its successors and assigns
(Seller and such persons, collectively, "Seller's Indemnified Persons"), and
shall reimburse Seller's Indemnified Persons, for, from and against all Losses
imposed on or incurred by Seller's Indemnified Persons, directly or indirectly,
relating to, resulting from or arising out of: (a) any inaccuracy in any
representation or warranty, or any breach or non-fulfillment of any covenant,
agreement or other obligation of Buyer or Parent under this Agreement or any
certificate or other document delivered or to be delivered pursuant hereto; and
(b) any obligation of Buyer relating to the License Agreements or any other
matter arising out of or related to the operation of the Business arising after
the Closing Date.



                                       21
<PAGE>

         12.3. Notice and Defense of Third Party Claims. If any action, claim or
proceeding shall be brought or asserted under this Article 12 against an
indemnified party or any successor thereto (the "Indemnified Person") in respect
of which indemnity may be sought under this Article 12 from an indemnifying
person or any successor thereto (the "Indemnifying Person"), the Indemnified
Person shall give prompt written notice of such action or claim to the
Indemnifying Person who shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Person and the
payment of all expenses; except that any delay or failure to so notify the
Indemnifying Person shall relieve the Indemnifying Person of its obligations
hereunder only to the extent, if at all, that it is prejudiced by reason of such
delay or failure. The Indemnified Person shall have the right to employ separate
counsel in any of the foregoing actions, claims or proceedings and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of the Indemnified Person unless both the Indemnified
Person and the Indemnifying Person are named as parties and the Indemnified
Person shall in good faith determine that representation by the same counsel is
inappropriate due to material conflicts of interest. In the event that the
Indemnifying Person, within ten days after notice of any such action or claim,
fails to assume the defense thereof, the Indemnified Person shall have the right
to undertake the defense, compromise or settlement of such action, claim or
proceeding for the account of the Indemnifying Person, subject to the right of
the Indemnifying Person to assume to the defense of such action, claim or
proceeding with counsel reasonably satisfactory to the Indemnified Person at any
time prior to the settlement, compromise or final determination thereof.
Anything in this Article 12 to the contrary notwithstanding, the Indemnifying
Person shall not, without the Indemnified Person's prior written consent, settle
or compromise any action or claim or proceeding or consent to entry of any
judgment with respect to any such action or claim that requires solely the
payment of money damages by the Indemnifying Person and that includes as an
unconditional term thereof the release by the claimant or the plaintiff of the
Indemnified Person from all liability in respect of such action, claim or
proceeding.

ARTICLE 13. COSTS.

         13.1 Finder's or Broker's Fees. Each of the parties represents and
warrants that it has not dealt with any broker or finder in connection with any

broker or other person is entitled to any commission or finder's fee in
connection with any of these transactions.

         13.2 Expenses. Each of the parties shall pay all costs and expenses,

implied, is intended to confer any rights or remedies under or by reason of this

action, in each case permanently restraining, enjoining or otherwise prohibiting
the transactions contemplated by this Agreement, and such order, decree, ruling
or other action shall have become final and nonappealable, or (iii) if the other
party shall have breached or failed to comply in all material respects with its
representations, warranties, covenants and agreements contained in this
Agreement; provided, however, that if such breach or failure is reasonably
capable of being cured on or before November 30, 1998 and such party commences
such cure as soon as practicable and diligently prosecutes (subject to any other
limitations of this Agreement) such cure, such party shall be entitled to
postpone the Closing Date for a period reasonably sufficient to effect such cure
to the reasonable satisfaction of the party asserting such breach or failure,
but in no event beyond November 30, 1998.

otherwise, including, without limitation, damages relating thereto, shall also

                                    SUBLEASE

         THIS SUBLEASE (the "Sublease") is made as of the 29 day of September,
1998, between HEALTHDESK CORPORATION, a California corporation, having its
principal place of business at 2560 Ninth Street, Suite 220, Berkeley,

                                    RECITALS:

         A. Sublandlord is tenant under an Office Lease (the "Prime Lease," a
complete copy of which is annexed hereto as Schedule A) dated September 11, 1995
with Parker Associates, a California limited partnership (the "Prime Lessor"),
relating to property identified as Suite 220 in Parker Plaza, 2560 Ninth Street,
Berkeley, California, more particularly described in the Prime Lease, and
referred to herein as the "Premises."

         B. Sublandlord desires to sublet to Subtenant, and Subtenant desires to
sublet from Sublandlord, all of the Premises.

         NOW, THEREFORE, for good and valuable consideration, the receipt of
which is hereby acknowledged, the parties hereby agree:

         1. Sublease. Sublandlord hereby subleases the Premises to Subtenant,
and Subtenant hereby subleases the Premises from Sublandlord, on the terms and
conditions hereinafter set forth.

         2. Term of Sublease. The Sublease shall commence on the date hereof
(the "Commencement Date") and shall be a month-to-month tenancy terminable upon
10 business days advance written notice by either party.

         3. Rent. Subtenant shall pay Sublandlord the Rent at the office of
Sublandlord first above appearing, or at such other place as Sublandlord may
designate in writing. Rent shall be payable in equal monthly installments in
advance on the first day of each calendar month during the Term.

         4. Occupancy. Subject to the terms and provisions hereinafter set
forth, Subtenant shall be permitted to enter into occupancy of the Premises on
the Commencement Date.



                                       1
<PAGE>

         5. Prime Lease; Inapplicable Provisions. This Sublease is subject to
and subordinate to the Prime Lease, and all defined terms used herein, unless
otherwise indicated, shall have the meanings given to them in the Prime Lease.
The term "Landlord" as used in the Prime Lease shall refer to Sublandlord
hereunder, "Tenant" as used in the Prime Lease shall refer to Subtenant
hereunder, "Commencement Date" shall refer to the Commencement Date of this
Sublease and "Term" shall refer to the Term of this Sublease, except as
otherwise expressly provided in this Sublease. The obligations of Sublandlord in
the Prime Lease shall be the obligations of Subtenant hereunder, and Subtenant
assumes and shall perform all of the terms of the Prime Lease to be performed by
Sublandlord as tenant thereunder with respect to the Premises for the term of
this Sublease, except to the extent the provisions of the Prime Lease are
inconsistent with or are superseded or supplemented by specific terms and
provisions of this Sublease. The following provisions of the Prime Lease shall
not apply to this Sublease:

                  (a)  The Term (paragraph 3(a));

                  (b)  Security Deposit (paragraph 15);

                  (c)  Rental Adjustment (paragraph 29);

                  (d)  Taxes Payable by Tenant (paragraph 30); and

                  (e)  Basic Operating Costs (Paragraph 38).

         6. Prime Lease Indemnity. Subtenant shall neither do nor permit
anything to be done which would cause the Prime Lease to be terminated or
forfeited by reason of any right of termination or forfeiture reserved or vested
in the Prime Lessor under the Prime Lease, and Subtenant shall indemnify and
hold Sublandlord harmless from and against all claims of any kind whatsoever by
reason of any breach or default on the part of Subtenant by reason of which the
Prime Lease may be terminated or forfeited.

         7. "As Is" Condition. Subtenant has inspected the Premises and accepts
the same from Sublandlord in its present condition "as is." Subtenant
acknowledges and agrees with Sublandlord that neither Sublandlord, nor any
employee of Sublandlord, nor other party claiming to act on Sublandlord's behalf
has made any representation, warranty, estimation, or promise of any kind or
nature whatsoever relating to the physical condition of the Premises.

         8. Prime Lessor Consent. The Sublease shall be of no force and effect,
and the parties shall have no rights or liabilities hereunder, until the terms
hereof are approved in writing by Prime Lessor. Either party can terminate this
Sublease if the contingency in the prior sentence has not been satisfied or
waived by September 30, 1998.

         9. Miscellaneous.

            (a) Each party warrants that it is authorized to enter into the
Sublease, that the person signing on its behalf is duly authorized to execute
the Sublease, and that no other signatures are necessary.

            (b) All prior understandings and agreements between the parties with
respect to the subject matter hereof are merged within this Sublease, which
alone fully and completely sets forth the understanding of the parties. This
Sublease shall not be modified, altered or amended in any way except by
agreement in writing, signed by the parties hereto.

            (c) The terms, covenants and conditions contained in this Sublease
shall be binding on and inure to the benefit of the parties hereto and their
respective permitted successors and permitted assigns.

            (d) If any provision of the Sublease is invalid or unenforceable to
any extent, then that provision and the remainder of this Sublease shall
continue in effect and be enforceable to the fullest extent permitted by law.

            (e) The parties chose this Sublease document because it is fair to
both parties. Therefore, the parties agree that it shall be construed as if both
parties were equally responsible for drafting the Sublease and the rule of
construction of construing against the drafter shall not apply.

            (f) This Sublease shall be governed by the laws of the State of
California.

            (g) This Sublease shall not be binding unless signed by both parties
and an originally signed counterpart is delivered to Subtenant.

            (h) Subtenant warrants and represents to Sublandlord that this
Sublease and the transaction contemplated hereby is legally binding on, and
enforceable against Subtenant in accordance with its terms.

            (i) Notices shall be sent and deemed to have been given as provided
in Paragraph 28 of the Prime Lease, to Sublandlord and Subtenant at their
addresses in the first paragraph of this Sublease.

BERKELEY, CALIF. (Aug. 21, 1998) - HealthDesk Corporation (Nasdaq: HDSK - news)
today announced the signing of a definitive agreement to merge with MC
Informatics. MC Informatics, a privately held company, is an outsourcing company

healthcare information system vendors. If the Merger is consummated, HealthDesk
would issue approximately 5 million shares of Common Stock to the current
shareholders of MC Informatics, representing approximately 40% of the total
outstanding shares following the merger.

The merger is subject to customary conditions, including, among others, due
diligence reviews by the parties, regulatory approvals and approval by the
shareholders of both companies.

In connection with the previously announced strategic realignment of the
Company, HealthDesk also intends to seek a buyer for the current consumer
healthcare business and technology of the company. Assuming the successful
completion of such transaction and the merger, the Company would continue to
operate the outsourcing business of MC Informatics.

This release contains forward looking statements that are subject to risks and
uncertainties, including, but not limited to, whether the Company can
successfully complete the merger with MC Informatics and if completed,
successfully operate the business of MC Informatics following the Merger and
whether the Company can negotiate and complete a sale of its existing HealthDesk
OnLine Business and the terms and conditions of such sale. The Company is also
subject to risk associated with competitive products and pricing, product demand
and market acceptance, new product development, reliance on key strategic
alliances, fluctuations in operating results and other risks detailed from time
to time in the Company's filings with the Securities and Exchange Commission.
