                                                                              11
<PAGE>

Company or the LLC or the use of their respective properties (including any
leased properties) and assets, and neither the Company nor the LLC has received,
and does not know of the issuance or threatened issuance by any Governmental
Entity, of any notices of violation or alleged violation of any Law applicable

has manufactured, packaged, shipped, advertised, labeled and sold its products
complies in all material respects with all applicable Laws pertaining thereto.

     2.8  Litigation.  There is no action, suit, claim, investigation or
          ----------
proceeding, whether at law or in equity (each, a "Legal Proceeding"), pending

events or circumstances, have substantially similar allegations or seek

reasonably be expected to result in a Company Material Adverse Effect. None of
the matters listed in Section 2.8 of the Schedule of Exceptions could, if
adversely determined, either individually or in the aggregate, reasonably be
expected to have a Company Material Adverse Effect. To the knowledge of the
Company and each of the Shareholders, no event has occurred and no circumstance,
matter or set of facts exist which would constitute a valid basis for the
assertion by any third party of any claim or Legal Proceeding, other than those
listed in Section 2.8 of the Schedule of Exceptions, which is or would
reasonably be likely to result in a Company Material Adverse Effect. There is no
outstanding or, to the knowledge of the Company or any of the Shareholders,
threatened, judgment, injunction, order or consent or similar decree or
agreement of any Governmental Entity against, naming the Company, the LLC, or,
to the knowledge of the Company or any of the Shareholders, affecting any of its
Assets or any assets of the LLC.

prior to the Closing Date will have established, current accruals that are

any Taxes.

          ---------
true, correct and complete list of all employees of the Company as of the date

Shareholders, there is no basis for the assertion of any claim or liability of
any nature against the Company or the LLC, which was not fully reflected in,
reserved against or otherwise described in the balance sheet included in the
Financial Statements. Since June 30, 2000, neither the Company nor the LLC has
incurred any indebtedness, obligation or liability of any kind (whether accrued,
absolute, contingent or otherwise, and whether due or to become due or asserted
or unasserted) that would be required to be disclosed on a balance sheet

Company nor any of the Shareholders has received any notice or claim (whether
written, oral or otherwise) challenging either the Company's or the LLC's
ownership or rights in such Intellectual Property or suggesting that any other
Person (except, under certain circumstances, the licensor thereof) has any claim
of legal or beneficial ownership with respect thereto;

               (ii)   All Intellectual Property of the Company is legally valid
and enforceable without any material qualification, limitation or restriction on

               -------------------------------------
the LLC has conducted the Business, and has not used or enforced (or failed to
use or enforce) any Intellectual Property, in a manner that would result in the
abandonment, cancellation or unenforceability of any item of the Intellectual
Property listed in Section 2.15 of the Schedule of Exceptions, and neither the
Company nor the LLC has taken or failed to take any action that would result in
the forfeiture or relinquishment of any Intellectual Property used in the
conduct of the Business. Neither the Company nor any of the Shareholders knows
of any new developments in any of the Intellectual Property owned, created or
used by the Company or its competitors or the LLC that might reasonably be
expected to result in a Company Material Adverse Effect.

          (d)  Protection and Maintenance of Intellectual Property.  Each of the
               ---------------------------------------------------
Company and the LLC (i) has taken all reasonable steps to (A) protect the

exclusive or otherwise) in such Intellectual Property and, except pursuant to
reasonably prudent safeguards, no third party has received any confidential
information relating to such Intellectual Property, (ii) neither the Company nor
the LLC is under any contractual or other obligation to disclose to any third
party any such Intellectual Property except pursuant to prudent and reasonable
safeguards, and (iii) there are no known significant defects therein and such

                                                                              16

contractual or other arrangement such person or entity may have with the Company
or the LLC.

     For purposes of this Agreement, the term "Default" means, with respect to
                                               -------
any Contract, (x) any material breach of or default under such Contract, (y) any
event which could (either with or without notice or lapse of time or both) give
rise to any right of termination, cancellation or acceleration or any obligation
to repay with respect to such Contract, or (z) any event which could result in
either a material increase in the obligations or liabilities of, or a loss of
any material benefit to which, the party in question or any of its affiliates
may be entitled or subject to under such Contract.

          (c)  Certain Agreements.  Neither the execution and delivery of this
               ------------------
Agreement nor the consummation of the transactions contemplated hereby will (i)
result in any payment (including, without limitation, severance, unemployment
compensation, golden parachute, bonus or otherwise) becoming due to any director
or employee of the Company or the LLC, (ii) materially increase any benefits
otherwise payable under any Benefit Plan (as defined in Section 2.24) or (iii)
result in the acceleration of the time of payment or vesting of any such
benefits. Each of the Company and the LLC is in compliance in all material
respects with all applicable laws, agreements and contracts relating to
employment, employment practices, wages, hours, and terms and conditions of
employment, including, but not limited to, employee compensation matters. The
Company believes it has satisfactory labor relations; nothing has come to the
attention of the Company or any of the Shareholders as a result of the
negotiation or entering into of this Agreement that would lead the Company or
any of the Shareholders to believe that the consummation of the transactions
contemplated hereby will have a Company Material Adverse Effect on labor
relations. Except as set forth in the Schedule of Exceptions, neither the
Company nor the LLC has employment contracts or material consulting agreements
currently in effect that are not terminable at will or upon reasonable notice
(other than agreements with the sole purpose of providing for the
confidentiality of proprietary information or assignment of inventions), except
as such termination rights are limited under applicable employment laws.

                                                                              19

conduct of its business.

     2.20  Restrictions on Business Activities.  There is no material agreement,
           -----------------------------------
judgment, injunction, order or decree binding upon the Company that has or could
reasonably be expected to have the effect of prohibiting or impairing any
business practice of the Company or the LLC, any acquisition of property by the
Company or the conduct of the Business by the Company that would be reasonably
likely to have a Company Material Adverse Effect.

     2.21  Books and Records.  The books, records and accounts of the Company
           -----------------
and the LLC (a) have in all material respects been maintained in accordance with
good business practices on a basis consistent with prior years and (b) are
stated in reasonable detail and in all material respects accurately and fairly
reflect the transactions and dispositions of the assets of the Company and the
LLC. Each of the Company and the LLC has devised and maintains a system of
internal accounting controls sufficient to provide reasonable assurances that
(x) transactions are executed in accordance with management's general or
specific authorization; and (y) transactions are recorded as necessary (i) to
permit accurate preparation of financial statements and (ii) to maintain
accountability for assets.

     2.22  Allocation of Merger Consideration.  The allocation of the Merger
           ----------------------------------
Consideration among the holders of the shares of Company Stock as set forth in
Exhibit A is correct pursuant to the terms and conditions of this Agreement,
---------

                                                                              20

assuming that no Company Stock is submitted for transfer after the date of this
Agreement.

     2.23  No Misrepresentation.  Neither this Agreement (including the
           --------------------
Exhibits and Schedules hereto) nor any information supplied to Certicom by or on
behalf of the Company or any of the Shareholders in connection with this
Agreement or the transactions contemplated hereby or thereby contains or will
contain any untrue statement of a material fact or omits or will omit to state a
material fact necessary to make the statements contained herein or therein, in
light of the circumstances under which they were made, not misleading.

     2.24  Benefit Plans.
           -------------

           (a) Section 2.24 of the Schedule of Exceptions sets forth a true,
correct and complete list of all "employee pension benefit plans" (as defined in
Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) ("Pension Plans") and all "employee welfare benefit plans" (as
  -----      -------------
defined in Section 3(1) of ERISA), bonus, stock option, stock purchase, deferred
compensation plans or arrangements and other employee fringe benefit plans
maintained, or contributed to, by the Company or the LLC for the benefit of any
current or former employees of the Company or the LLC or with respect to which
Company or the LLC has any liability (all the foregoing, including Pension
Plans, being herein called "Company Benefit Plans").  The Company has delivered
                            ---------------------
to Certicom true, complete and correct copies of (i) each Benefit Plan (or, in
the case of any unwritten Benefit Plans, descriptions thereof), (ii) the two
most recent annual reports on Form 5500 (including all schedules and attachments
thereto) filed with the Internal Revenue Service (including all schedules and
attachments thereto) filed with the Internal Revenue Service with respect to
each Benefit Plan (if any such report was filed), (iii) the most recent summary
plan description for each Benefit Plan for which such a summary plan description
has been prepared and (iv) each trust agreement, group annuity contract or other
funding and financing arrangement relating to any Benefit Plan.

           (b) Each Benefit Plan has been administered in all material respects
in accordance with its terms. The Company and the LLC and all Benefit Plans are
in compliance in all material respects with the applicable provisions of ERISA,
the Code, all other applicable Laws and all applicable collective bargaining
agreements. Except as set forth in Section 2.24 of the Schedule of Exceptions,
there are no proceedings pending, or, to the knowledge of the Company or any of
the Shareholders, threatened against or involving any Benefit Plan and, there
are no investigations by any Governmental Entity or other claims (except routine
claims for benefits payable in the normal operation of the Benefit

                                                                              21
<PAGE>

     Plans) pending or, to the knowledge of the Company or any of the
     Shareholders, threatened against or involving any Benefit Plan or asserting
     any rights to benefits under any Benefit Plan. Except as set forth in
     Section 2.24 of the Schedule of Exceptions, none of the proceedings,
     investigations and claims listed in such Section 2.24 as to which there is
     at least a reasonable possibility of adverse determination, would have, if
     so determined, individually or in the aggregate, a Company Material Adverse
     Effect. Except as set forth in Section 2.24 of the Schedule of Exceptions,
     to the knowledge of the Company and each of the Shareholders, there are no
     unasserted claims of the type that would be required to be disclosed in
     such Section 2.24, if pending or threatened, that are considered probable
     of assertion and that if asserted would have at least a reasonable
     possibility of an adverse determination.

               (c) All required contributions to, and distributions from, each
     of the Benefit Plans have been made. Neither the Company nor the LLC nor
     any entity required to be treated with the Company or the LLC as a single
     employer under Section 414(b), (c) or (m) of the Code maintains any plan
     that is subject to Title IV of ERISA or Chapter 43 of the Code, where such
     requirement would be reasonably likely to have a Company Material Adverse
     Effect. To the knowledge of the Company and each of the Shareholders, no
     event has occurred with respect to any Benefit Plan that could result in
     the imposition of a lien under ERISA, the Code or any other Applicable Law
     on any of the assets of the Company.

         2.25  Environmental Matters.
               ---------------------

               (a) Each of the Company and the LLC is, and at all times has
     been, in full compliance with, and has not been and is not in violation of
     or liable under, any legal requirement designed to minimize, prevent,
     punish, or remedy the consequences of actions that damage or threaten any
     environmental medium or natural resource (including, but not limited to,
     soil, surface waters, and ambient air) or public health and safety
     ("Environmental Law"). Neither the Company nor the LLC nor any of  the
      -------------------
     Shareholders has any basis to expect or has received any actual or
     threatened order, notice or communication from (i) any Governmental Entity
     or private citizen acting in the public interest, or (ii) the current or
     prior owner or operator of any real property or leasehold currently or
     formerly owned by the Company or the LLC, of any actual or potential
     violation or failure to comply with any Environmental Law, or of any actual
     or threatened obligation to bear the cost of any cost, damage, expense,
     liability, obligation or other responsibility arising from or under any
     Environmental Law ("Environmental Liabilities") with respect to any
                         -------------------------
     property or assets (whether real, personal, or mixed) in which the Company
     or the LLC or any other person for whose conduct the Company or the LLC is
     or may be responsible has or had an interest.

                                                                              22
<PAGE>

               (b)  There are no pending or, to the knowledge of the Company or
     any of the Shareholders, threatened claims, encumbrances, or other
     restrictions of any nature, resulting from any Environmental Liabilities
     with respect to any property or assets (whether real, personal, or mixed)
     in which the Company or the LLC or any other person for whose conduct the
     Company or the LLC is or may be responsible has or had an interest.

               (c)  Neither the Company nor any of the Shareholders has any
     knowledge of or basis to expect, or has received any citation, directive,
     inquiry, notice, order, summons, warning, or other communication that
     relates to (i) any waste or other substance that is listed, defined,
     designated, or classified as, or other wise determined to be, hazardous,
     radioactive, toxic, or a pollutant or a contaminant under or pursuant to
     any Environmental Law ("Hazardous Materials"); (ii) any activity
                            ---------------------
     involving Hazardous Materials (including, but not limited to, generation,
     distribution, or storage thereof).

         2.26  Tangible Net Worth.  The Company's "Adjusted Working Capital"
               ------------------                  ------------------------
     (cash plus accrued accounts receivable net of reserves minus accrued
     salary, taxes and accounts payable, determined in accordance with generally
     accepted accounting principles consistently applied) is, and as of Closing
     Date the Company's Adjusted Working Capital shall be, at least $100,000
     ("Minimum Adjusted Working Capital"). The Company's Adjusted Working
       --------------------------------
     Capital as of the Closing Date shall reflect all accrued and unpaid fees
     and expenses of attorneys and accountants ("Professional Fees") of no
                                                -------------------
     greater than US$75,000, and shall reflect, as an asset, Certicom's
     commitment, pursuant to Section 10.8, to pay up to US$75,000 of
     Professional Fees that are reflected as a liability.

         2.27  Merger of LLC and the Company.  The merger of the LLC and the
               -----------------------------
     Company (a) was duly executed and effectively converted all ownership
     interest in and assets of the LLC into capital stock in and assets of the
     Company, and (b) in all respects complied with and satisfied the

     financial and business matters that he is capable of evaluating the merits
     and risks of the prospective investment in the Certicom Common Shares, and

                            MERGER SUB AND CERTICOM

    Merger Sub and Certicom hereby jointly and severally represent and warrant
to the Company and the Shareholders as follows:

    4.1  Organization, Standing and Power.  Each of Merger Sub and Certicom is
         --------------------------------
duly organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation or organization and has all requisite corporate
power and authority to own, lease and operate its properties and to carry on its
business as now being conducted. Each of Merger Sub and Certicom is duly
qualified and in good standing to conduct business in each jurisdiction in which
the business it is conducting, or the operation, ownership or leasing of its
properties, makes such qualification necessary, except where the failure to be
so qualified would not result in a Certicom Material Adverse Effect (as defined
below).

     4.2  Authority.  Each of Merger Sub and Certicom has all requisite power
          ---------
and authority to execute and deliver this Agreement and to perform fully its
obligations hereunder. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly authorized
by all necessary action on the part of each of Merger Sub and Certicom. This
Agreement has been duly executed and delivered by each of Merger Sub and
Certicom and, assuming this Agreement constitutes the valid and binding
agreement of the other parties hereto, this Agreement constitutes the legal,
valid and binding obligation of each of Merger Sub and Certicom, enforceable
against each of Merger Sub and Certicom in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws now or hereafter in effect relating to creditors' rights and remedies
generally and subject, as to enforceability, to general principles of equity
(regardless of whether enforceability is considered in a proceeding at law or in
equity).

                                                                              28

          ------------------------------
Merger Sub will have taken all necessary action to issue the Certicom Common
Shares to be issued by it in connection with the Merger. All Certicom Common
Shares to be issued by Certicom in connection with the Merger will, at the time
of issuance, be validly issued, fully paid and nonassessable, and no Person will
have any preemptive right of subscription or purchase in respect thereof; in
addition, such shares will be issued free and clear of any Encumbrances (except
pursuant to applicable securities or "blue sky" laws and except as set forth in
the Escrow Agreement).

     4.5  Exchange Listing.  Certicom shall use its best efforts to list the
          ----------------
Certicom Common Shares on the Toronto Stock Exchange prior to the Closing Date
and continue such listing until at least thirty (30) trading days following the
eighteen month anniversary of the Closing Date.

     4.6  No Violations Resulting From Transactions.  The execution and
          -----------------------------------------
delivery by Merger Sub and Certicom of this Agreement and the consummation of
the transactions contemplated hereby and thereby by each of Merger Sub and
Certicom will not (a) conflict with or violate any provision of the Articles of
Continuance or Bylaws of Certicom or the Certificate of Incorporation or Bylaws
of Merger Sub, (b) require any consent, waiver, approval, authorization or
permit of, or filing with or notification to, any Governmental Entity other
than: (i) the office of the California Secretary of State and the Delaware
Secretary of State and (ii) such filings, authorizations, orders and approvals
as may be required under the Securities Act (Ontario), any other applicable
federal, provincial or state securities laws and the rules of The Toronto Stock

Certicom is a party or by which any of their respective assets are bound, or (d)
violate any Law applicable to Merger Sub or Certicom or by which any of their
respective assets are bound.

     4.7  Litigation.  There is no suit, claim, action, proceeding or
          ----------
investigation pending or, to the knowledge of Certicom, threatened against
Certicom or Merger Sub which, individually or in the aggregate, questions the
validity of this Agreement or any action to be taken by Certicom or Merger Sub
in connection with the consummation of the transactions contemplated hereby or

                                                                              29

could otherwise prevent or delay the consummation of the transactions
contemplated by this Agreement.

          4.8  OSC Reports.
               -----------

               (a) Since January 1, 1997, Certicom has filed all forms, reports
     and documents with the Ontario Securities Commission ("OSC") required to be
                                                            ---
     filed by it pursuant to the Securities Act (Ontario) and the regulations
     promulgated thereunder and the applicable rules and policies of the OSC
     (such forms, reports and documents collectively referred to as the "OSC
                                                                         ---
     Reports"), all of which complied when filed in all material respects with
     -------
     the applicable requirements of such statute, regulations, policies and
     rules. None of the OSC Reports at the time filed or as subsequently
     amended, contained any untrue statement of a material fact or omitted to
     state a material fact required to be stated therein or necessary in order
     to make the statements made therein, in light of the circumstances under
     which they were made, not misleading.

               (b) The consolidated balance sheets and the consolidated
     statements of operations, retained earnings and cash flows (including the
     related notes thereto) of Certicom contained in the OSC Reports present
     fairly the consolidated financial positions and the consolidated results of
     operations and cash flows of Certicom and its consolidated subsidiaries as
     of the dates and for the periods presented therein in conformity in all
     material respects with Canadian generally accepted accounting principles
     applied on a consistent basis during the periods involved, except as
     otherwise noted therein and subject, in the case of quarterly financial
     statements, to normal and recurring year-end audit adjustments.

          4.9  Absence of Certain Changes or Events.  Since April 30, 2000,
               ------------------------------------
there has been no material adverse change in the business, assets, financial
conditions or results of operations of Certicom.

          4.10 Merger Sub.  All of the issued and outstanding stock of Merger
               ----------
Sub is owned, and will be owned immediately prior to the Effective Time,
directly by Certicom. Except for obligations incurred in connection with its
incorporation or organization or the negotiation of this Agreement or the
consummation of the transactions contemplated hereby, Merger Sub has neither
incurred any obligation or liability nor engaged in any business or activity of
any type or kind whatsoever or entered into any agreement or arrangement with
any Person.

          4.11 Intent Consistent with Reorganization.  Except for actions
               -------------------------------------
which Certicom deems reasonably necessary in order to comply with other Sections
of this Agreement, Certicom has no present plan or intent to take any action
that

                                                                              30

would cause the Merger to fail to qualify as a reorganization within the meaning
of Section 368(a) of the Code.

the case may be, which breach has not been cured within ten (10) business days

of a court or other competent authority preventing the consummation of the
transactions contemplated by this Agreement shall have become final and non-
appealable; or

          (c)  by either the Company or Certicom, if the Closing shall not have
occurred on or before September 20, 2000; provided that (i) in the event that
any temporary restraining order, preliminary or permanent injunction or other
order shall be issued by any court of competent jurisdiction or other legal
restraint or prohibition occurs preventing the consummation of the transactions

this Section 8.1(c) shall not be available to (A) Certicom, if such party has
breached any of its representations, warranties or covenants hereunder in any
material respect and such breach has been the cause of or resulted in the
failure of the Closing to occur on or before such date (as such date may be
extended under clause (i) above) or (B) the Company, if either the Company or
any one or more of the Shareholders has breached any of its or his respective
representations, warranties or covenants hereunder in any material respect and
such breach has been the cause of or resulted in the failure of the Closing to
occur on or before such date (as such date may be extended under clause (i)

          ---------------------
by either the Company or Certicom as provided in Section 8.1, this Agreement
shall forthwith become void and there shall be no liability or obligation on the
part of any party or any of their respective Affiliates, officers, directors,

intentional or knowing breach by any party of any of its representations or
warranties, or of any of its covenants or agreements, in each case as set forth
in this Agreement.

     8.3  Amendment.  Subject to applicable Law, this Agreement may be amended,
          ---------
modified or supplemented only by written agreement signed by the Company, on
behalf of itself and the Shareholders, and Certicom, on behalf of

                                                                              41

itself and Merger Sub, at any time prior to the Closing Date with respect to any
of the terms contained herein, and each party agrees to be bound by any such
amendment, modification or supplement, provided that no such amendment shall

is agreed to in writing by each such differently or disproportionately affected
Shareholder.

     8.4  Extension; Waiver. At any time prior to the Closing Date, the Company
          -----------------
(on behalf of itself and the Shareholders), on the one hand, and Certicom (on
behalf of itself and Merger Sub), on the other hand, may: (a) extend the time
for the performance of any of the obligations or other acts of the other
parties; (b) waive any inaccuracies in the representations and warranties
contained herein or in any document delivered pursuant hereto; and (c) waive

agreement to any such extension or waiver shall be valid only if set forth in a

Shareholders), or by Certicom (on behalf of itself and Merger Sub), as the case
may be. The failure of any party to assert any of its rights hereunder shall not
constitute a waiver of such rights.

                                  ARTICLE IX
                           SURVIVAL; INDEMNIFICATION

                                                                       --------
Period").  Notwithstanding anything to the contrary contained herein, (i) no

     9.2  Indemnification.
          ---------------

          (a)  Indemnification Provisions in General. Subject to the provisions
               -------------------------------------
of Section 9.1, each of the Shareholders shall jointly and severally indemnify
and hold harmless Certicom, Merger Sub, the Surviving Corporation and their
respective Affiliates, officers, directors, stockholders, representatives and
agents (collectively the "Indemnitees") from and against and in respect of any
                          -----------
and all Losses (as defined below) incurred by, resulting from, arising out of,
relating to, imposed upon or incurred by Certicom or any other Indemnitee by
reason of:

               (i)   any inaccuracy in or breach of any of the Company's
representations, warranties, covenants or agreements contained in this
Agreement; and

               (ii)  any misrepresentation contained in any statement or
certificate furnished to Certicom or any other Indemnitee by or on behalf of the
Company in connection with the transactions contemplated by this Agreement.

For purposes of this Agreement, the term, "Losses" means any and all

deficiencies, judgments, settlements, demands, claims, suits, actions or causes

suits, proceedings, assessments, judgments or appeals, and in seeking
indemnification therefor), net of any recovery made under the tail insurance
policy with respect to the same.

          (b)  No Shareholder of the Company shall be required to indemnify any
Indemnitee for any Losses until and only to the extent that the aggregate amount
of all Losses under all claims shall exceed U.S. $100,000 (the "Floor");
                                                                -----
provided, however, the Floor shall not apply to Losses attributable to Sections
--------  -------
2.9, 2.24, or 2.25, and the Shareholders shall indemnify the Indemnitees for all
such Losses. Except as specifically provided in Section 9.2(d), the maximum

Losses with respect to Sections 2.9, 2.24, and 2.25, and (ii) the amount (if
any) recoverable by the Indemnities pursuant to the Escrow for other Losses.

                                                                              43

          (d)  The rights and remedies of Certicom and any other Indemnitees
against the Shareholders for any claims with respect to the matters set forth in

forth in this Article IX; provided that no provision of this Agreement shall
limit, in any manner, any remedy at law or in equity to which any Indemnitee
shall be entitled against the Company or any Shareholder for specific
performance (whether or not pursuant to Section 10.7), or as against the
Shareholders as a result of fraud or intentional misrepresentation in which any
of the Shareholders participates.

          (e)  Losses shall be paid first from the Escrow. Subject to Section
9.2(b), the Shareholders will be jointly and severally liable to the extent they
cannot be satisfied from the Escrow.

     9.3  Procedures for Indemnification.
          ------------------------------

          (a)  A claim for indemnification hereunder (an "Indemnification
                                                          ---------------
Claim") shall be made in accordance with the Escrow Agreement and, in the case
-----
of a Third Party Claim (as defined in Section 9.4), containing (by attachment or
otherwise) such other information as the Indemnitee shall have concerning such
Third Party Claim.

          (b)  If the Indemnification Claim involves a Third Party Claim, the
procedures set forth in Section 9.4 hereof shall be observed by the Indemnitee
and the Shareholders.

     9.4  Defense of Third Party Claims. Should any claim be made or suit,
          -----------------------------
audit, examination or other proceeding be instituted against an Indemnitee
which, if prosecuted successfully, would be a matter for which such Indemnitee
is entitled to indemnification under this Article IX (without regard to Section
9.2(b)) (a "Third Party Claim"), the obligations and liabilities of the parties
            -----------------
hereunder with respect to such Third Party Claim shall be subject to the
following terms and conditions:

          (a)  The Indemnitee shall give each Shareholder and the Escrow Agent
written notice of any such Third Party Claim promptly after receipt by the
Indemnitee of notice thereof, and the Shareholder Representative may, subject to

                                                                              44
<PAGE>

the prior written consent of Certicom, undertake control of the defense thereof
by counsel of its own choosing reasonably acceptable to the Indemnitee. The
Indemnitee may participate in the defense through its own counsel at its own
expense. If Certicom does not consent to the Shareholders undertaking the
defense of such Third Party Claim, or the Shareholders fail or refuse to
undertake the defense of such Third Party Claim within fifteen (15) days after
written notice of such claim has been delivered to the Shareholders by the
Indemnitee, the Indemnitee shall have the right to undertake the defense,
compromise and, subject to Section 9.5, settlement of such Third Party Claim
with counsel of its own choosing. In the circumstances described in the
preceding sentence, the Indemnitee shall, promptly upon its assumption of the
defense of such Third Party Claim, make an Indemnification Claim as specified in
Section 9.3(b), which shall be deemed an Indemnification Claim that is not a
Third Party Claim for the purposes of the procedures set forth herein. Failure
of the Indemnitee to furnish written notice to a Shareholder or the Escrow Agent
of a Third Party Claim shall not release the Shareholders from their obligations
hereunder, except to the extent they are prejudiced by such failure.

          (b)  The Indemnitee and the Shareholders shall cooperate with each
other in all reasonable respects in connection with the defense of any Third
Party Claim, including making available records relating to such claim and
furnishing employees of the Indemnitee as may be reasonably necessary for the
preparation of the defense of any such Third Party Claim or for testimony as
witness in any proceeding relating to such claim.

          (c)  Unless the Shareholders have failed to fulfill their obligations
under this Article IX, no settlement by the Indemnitee of a Third Party Claim
shall be made without the prior written consent by or on behalf of the
Shareholders which consent shall not be unreasonably withheld or delayed. If the
Shareholders have assumed the defense of a Third Party Claim as contemplated by
this Section 9.4, no settlement of such Third Party Claim may be made by the
Shareholders without the prior written consent by or on behalf of the
Indemnitee, which consent shall not be unreasonably withheld or delayed.

     9.5  Manner of Indemnification.
          -------------------------

          (a)  To provide a fund against which an Indemnitee may assert claims
of indemnification under this Article IX, the Escrow Shares shall be deposited
into Escrow pursuant to the Escrow Agreement in accordance with the provisions
of Section 1.9 hereof. The Escrow Shares so deposited shall be held and
distributed in accordance with the Escrow Agreement.

                                                                              45
<PAGE>

          (b)  Each claim for indemnification asserted against the Shareholders
pursuant to this Article IX shall be made only in accordance with this Article
IX and the Escrow Agreement.

     10.2 Counterparts. This Agreement may be executed in two or more
          ------------
counterparts, each of which shall be considered an original and all of which
shall be considered one and the same agreement and shall become effective when
two or more counterparts have been signed by each of the parties and delivered
to the other parties, it being understood that all parties need not sign the
same counterpart.

     10.3 Entire Agreement; No Third Party Beneficiaries. This Agreement,
          ----------------------------------------------
together with the Exhibits and Schedules, constitutes the entire agreement of
the parties with respect to the subject matter hereof, and supersedes all prior
oral and written and all contemporaneous oral, agreements and understandings
among the parties with respect to the subject matter hereof. This Agreement is
not intended to confer upon any Person, other than the parties, any rights or
remedies hereunder, except that: (i) the Indemnitees (and their successors and
assigns) are express intended third party beneficiaries of Article IX of this
Agreement and, to the extent relevant thereto, of Article X, and, as such, each
of such persons is entitled to rely on the provisions thereof as if a party
hereto.

     10.4 Governing Law. This Agreement shall be governed and construed in
          -------------
accordance with the laws of the State of California, without giving effect to
the principles of conflicts of law thereof.

                                                                              47
<PAGE>

     10.5 Severability. If any term or other provision of this Agreement is
          ------------
invalid, illegal or unenforceable, all other provisions of this Agreement shall
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to any party. In the event that the enforceability of any non-
competition or similar covenants contained herein is called into question as the
result of time, geographical or other applicable limitations specified in such
covenants, such time, geographical or other applicable limitations shall be
deemed modified to the minimum extent necessary to render the applicable
provisions of such covenants enforceable.

     10.6 Assignment. Neither this Agreement nor any of the rights, interests or
          ----------
obligations hereunder shall be assigned by any of the parties hereto (whether by
operation of law or otherwise) without the prior written consent of the other
parties; provided that Certicom may assign its rights and obligations to any
Affiliate, but no such assignment shall relieve Certicom of its obligations
hereunder if such assignee does not perform such obligations. Subject to the
preceding sentence, this Agreement will be binding upon, inure to the benefit of
and be enforceable by the parties and their respective successors and assigns.

     10.7 Specific Performance.  The parties acknowledge that irreparable damage
          --------------------
would result if this Agreement were not specifically enforced, and they
therefore consent that the rights and obligations of the parties under this
Agreement may be enforced by a decree of specific performance issued by a court
of competent jurisdiction.  Such remedy shall, however, not be exclusive and
shall be in addition to any other remedies which any party may have under this
Agreement or otherwise.  Each of the Shareholders acknowledges that his failure
to comply with any of the provisions of Section 3.2 will result in irreparable
harm for which there is no adequate remedy at law and that Certicom shall be
entitled, without the necessity of proving actual damages, to injunctive relief
in addition to damages and all other remedies which may otherwise be available
to Certicom.

     10.8 Fees and Expenses. All costs and expenses, including Professional
          -----------------
Fees, shall be paid by the party incurring such costs and expenses. Certicom
will pay Professional Fees of the LLC and the Corporation of up to US$75,000,
which commitment shall be reflected as an asset of the Company on the Company's
Adjusted Working Capital as of the Closing Date in accordance with Section 2.26.
Any Professional Fees incurred by the Company or the LLC in excess of US$75,000
shall be paid by the Shareholders.

     10.9 Definition of Knowledge and Ordinary Course. Whenever any fact or
          -------------------------------------------
matter is stated to be "to the knowledge of the Company," "to the

                                                                              48
<PAGE>

knowledge of the Company or any of the Shareholders" or any similar reference,
such reference shall mean that, (a) in the case of the Shareholders, any one or
more of the Shareholders knows of the existence or non-existence of such fact or
matter, and (b) in the case of the Company, any one or more of Mr. Cowing, Mr.
Harris, Mr. Moy knows of the existence or non-existence of such fact or matter.
Whenever the phrase "in the ordinary course of the Company's business,
consistent with past practices" or any phrase of similar meaning is used in this
Agreement, such reference shall be deemed to refer to the ordinary course of the
Company's business, consistent with the normal business practices of the Company
and the LLC as in effect on or prior to the date hereof.

     10.10 Construction; Interpretation. The headings contained in this
           ----------------------------
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement. Article, section, schedule,
exhibit, recital and party references are to this Agreement unless otherwise
stated. No party, nor its counsel, shall be deemed the drafter of this Agreement
for purposes of construing the provisions of this Agreement, and all provisions
of this Agreement shall be construed in accordance with their fair meaning, and
not strictly for or against any party.

     10.11 Certain Obligations.  Whenever this Agreement requires the Company to
           -------------------
take any action or to refrain from taking any action, such requirement shall be
deemed to include an undertaking on the part of each of the Shareholders to use
his best efforts to cause the Company to take such action or to refrain from
taking such action, as the case may be.

     10.12 Dispute Resolution.
           ------------------

           (a) Except for actions by any party seeking equitable, injunctive or
other relief as provided in Section 10.7, any controversy, dispute or claim
arising out of or relating to this Agreement (or the breach hereof) that cannot
be resolved by good faith negotiation between or among the parties shall be
finally submitted to JAMS for final and binding arbitration pursuant to the
comprehensive arbitration rules for commercial cases of JAMS and pursuant to the
law set forth in the United States Arbitration Act. Such arbitration shall be
held before a single arbitrator who shall be a retired California state judge.
The arbitrator may enter a default decision against any party who fails to
participate in the arbitration proceedings.

           (b) The decision of the arbitrator shall be final, unappealable and
binding, and judgment on the award rendered by the arbitrator may be entered in
any court having jurisdiction thereof. The arbitrator shall be authorized to
award any relief, whether legal or equitable, to the party so entitled to such
relief.

                                                                              49
<PAGE>

               (c)  In respect of any suit, action or other proceeding relating
to the enforcement of any award rendered by the arbitrator, each party
irrevocably submits to the non-exclusive jurisdiction of any state or federal
court located in the County of Alameda, State of California.

               (d)  The arbitrator shall be authorized to apportion its fees and
expenses and the reasonable attorney's fees and expenses of the parties as the
arbitrator deems appropriate. In the absence of any such apportionment, the fees
and expense of the arbitrator will be borne fifty percent (50%) by Certicom, on
the one hand, and fifty percent (50%) by the Shareholders, on the other, and
each party will bear the fees and expenses of its own attorney. Any such fees
and expenses borne by the Shareholders shall be paid out of the Escrow.

               (e)  The parties agree that this Section 10.12 has been included
to rapidly and inexpensively resolve any claims or disputes between or among
them with respect to this Agreement, and that this Section 10.12 shall be
grounds for dismissal of any action commenced by any party in any court with
respect to this Agreement, other than post-arbitration actions seeking to
enforce an arbitration award or other than any action contemplated by Section
10.7. The parties shall keep confidential, and shall not disclose to any person,
except as may be required by applicable Law, the existence of any controversy
hereunder, the referral of any such controversy to arbitration or the status or
resolution thereof.

                                                                              50

and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Certicom, Merger Sub, the Company, Mr. Cowing, Mr. Harris, and Mr.
Moy hereby agree as follows:

          1.   The parties agree that the date of the acquisition of the Company
by Certicom shall be September 12, 2000, and that effective control of the
Company, including the risks and rewards of ownership, passed to Certicom on

share of Company Stock issued and outstanding immediately prior to the Effective
Time (other than (i) shares held in the Company's treasury or by any subsidiary
of the Company, (ii) any Company Dissenting Shares (as defined in Section 1.10)
and (iii) shares held by Certicom, Merger Sub or any other subsidiary of

          3.   Except as expressly modified herein, the Merger Agreement remains
unmodified and in full force and effect. The parties hereto expressly ratify and
reaffirm the terms of the Merger Agreement as modified by this Amendment.

          4.   This Amendment may be executed in counterparts, each of which
shall be deemed an original and all of which together shall constitute one and
