                                                                    ------------

                 NON-COMPETITION AND NON-SOLICITATION AGREEMENT
                 ----------------------------------------------

     This Agreement is made between Entrust Technologies Inc., a Maryland
corporation ("Entrust"), and Alberto Yepez (the "Employee").

     WHEREAS, Entrust has entered into the Agreement and Plan of Merger by and
among Entrust, Enable Acquisition Corp. and Enable, Inc. (the "Company") dated
as of April 18, 2000  (the "Merger Agreement"), pursuant to which the Company
shall become a subsidiary of Entrust and the holders of capital stock and
options of the Company will receive stock or options of Entrust;

     WHEREAS, Entrust was induced to enter into the Merger Agreement on the
condition that the Employee execute this Agreement prior to the consummation of
the transactions contemplated in the Merger Agreement; and

     WHEREAS, the Employee is an owner of capital stock or options to acquire
the capital stock of the Company and will personally benefit from the
transactions contemplated by the Merger Agreement.

     NOW, THEREFORE, in consideration of (i) Entrust entering into the Merger
Agreement and consummating the transactions contemplated thereby, (ii) the
benefit to the Employee from the transactions contemplated in the Merger
Agreement and (iii) the employment or continued employment of the Employee by
Entrust or any of its subsidiaries, the Employee and Entrust agree as follows:

     1.  Non-Competition and Non-Solicitation. For a period of one year after
         ------------------------------------
the closing of the transactions contemplated by the Merger Agreement the
Employee will not, directly or indirectly:

         (a)  Engage in any business or enterprise (whether as owner, partner,
officer, director, employee, consultant, investor, lender or otherwise, except
as the holder of not more than 1% of the outstanding stock of a company) that
directly or indirectly competes with Entrust's business or the business of any
of its subsidiaries (which, for purposes of this Agreement, includes the
Company), including but not limited to the business of the Company and any
business or enterprise that develops, manufactures, markets, or sells any
product or service that competes with any product or service developed,
manufactured, marketed or sold, or planned to be developed, manufactured,
marketed or sold, by Entrust or any of its subsidiaries while the Employee was
employed by Entrust or any of its subsidiaries; or

        (b)  Either alone or in association with others (i) solicit, or
encourage any organization directly or indirectly controlled by the Employee to
solicit, any employee of Entrust or any of its subsidiaries to leave the employ
of Entrust or any of its subsidiaries, (ii) solicit for employment, hire or
engage as an independent contractor, or permit any organization directly or
indirectly controlled by the Employee to solicit for employment, hire or engage
as an independent contractor, any person who was employed by Entrust or any of
its subsidiaries at any time during the term of the Employee's employment with
Entrust or any of its subsidiaries;
<PAGE>

provided, that this clause (ii) shall not apply to any individual whose
--------
employment with Entrust or any of its subsidiaries has been terminated for a
period of one year or longer, or (iii) solicit business from or perform services
for or induce or attempt to induce, any customer, supplier, licensee or business
relation of Entrust or any of its subsidiaries to cease doing business with
Entrust or any of its subsidiaries, or in any way interfere with the
relationship between any customer, supplier, licensee or business relation of
Entrust or any of its subsidiaries.

        2.  Miscellaneous.
            -------------

            (a)  Extension.  If the Employee violates the provisions of Section
                 ---------
1, the Employee shall continue to be bound by the restrictions set forth in
Section 1 until a period of one year has expired without any violation of such
provisions.

            (b)  Not Employment Contract. The Employee acknowledges that this
                 -----------------------
Agreement does not constitute a contract of employment, does not imply that the
Company or any of its subsidiaries will continue his/her employment for any
period of time and does not change the at-will nature of his/her employment.

            (c)  Interpretation.  If any restriction set forth in Section 1 is
                 --------------
found by any court of competent jurisdiction to be unenforceable because it
extends for too long a period of time or over too great a range of activities or
in too broad a geographic area, it shall be interpreted to extend only over the
maximum period of time, range of activities or geographic area as to which it
may be enforceable. The parties intend that the non-competition and non-
solicitation provisions contained in this Agreement shall be deemed to be a
series of separate covenants, one for each and every county of each and every
state of the United States of America and each and every political subdivision
of each and every country outside the United States of America where this
provision is intended to be effective.

            (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.

            (e)  Waiver of Rights.  No delay or omission by Entrust in
                 ----------------
exercising any right under this Agreement will operate as a waiver of that or
any other right. A waiver or consent given by Entrust 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
Entrust and its subsidiaries and are considered by the Employee to be reasonable
for such purpose. The Employee agrees that any breach of this Agreement is
likely to cause Entrust substantial and irrevocable damage and therefore, in the
event of any such breach, the Employee agrees that Entrust, in addition to such
other remedies which may be available, shall be entitled to specific performance
and other injunctive relief.

            (g)  Governing Law.  This Agreement shall be governed by and
                 -------------
construed in accordance with the laws of the State of Maryland. Any action,
suit, or other legal proceeding

                                      -2-
<PAGE>

which is commenced to resolve any matter arising under or relating to any
provision of this Agreement shall be commenced only in a court of the State of
Maryland (or, if appropriate, a federal court located within Maryland), and
Entrust and the Employee each consents to the jurisdiction of such a court.

            (h)  Effectiveness.  This Agreement shall be effective upon, and
                 -------------
subject to, the closing of the transactions contemplated by the Merger
Agreement.

        THE EMPLOYEE ACKNOWLEDGES THAT HE/SHE HAS CAREFULLY READ THIS AGREEMENT
AND UNDERSTANDS AND AGREES TO ALL OF THE PROVISIONS IN THIS AGREEMENT.

Dear Paul:

     We are pleased to confirm our job offer of Senior Vice President,
enCommerce, Inc., a fully owner subsidiary of Entrust Technologies Inc.
("Entrust") and Executive Vice President, Marketing and Business Development of
Entrust reporting to John Ryan, President and CEO of Entrust.  This offer is
subject to the closing of the proposed merger between the Company and Entrust
(the "Closing") pursuant to the Agreement and Plan of Merger of dated April 18,
2000 among, inter alia, the Company, and Entrust (the "Merger Agreement"). After
            ----- ----
Closing you will also be appointed an Officer of Entrust.

     Your responsibilities will include leadership of the global marketing,
channel programs, and business development activities of the Entrust
Technologies, Incorporated.

     Your base salary, on an annualized basis, will be $200,000 US, which will
be paid biweekly.  Your salary and performance will be subject to review on an
annual basis, generally conducted in January of each year.

     Any stock options granted to you by the Company prior to the Closing will
be converted into stock options for the acquisition of common stock of Entrust
Technologies Inc. in the manner provided for in the Merger Agreement and subject
to the applicable stock option plan.

     You will also be eligible to participate in the executive bonus plan
according to its terms, which for 2000 is equivalent to a potential payment of
up to $100,000 on an annualized basis.  The first incremental payment will be
reduced by the amount of any quarterly bonus payment previously paid to you in
connection with the Company's 2000 fiscal year.  Any bonus awarded will be paid
in two equal increments per calendar year.  The bonus award for the first half
of 2000, payable in July, will be based on the six-month performance of the
Company.  The bonus award for the second half of 2000, payable in January 2001,
will be based on the second half achievement of objectives of Entrust.

     In addition, you will be eligible for additional grants of stock options to
purchase shares of common stock of Entrust Technologies Inc. with an exercise
price equal to the fair market value of the common stock on the date of grant in
accordance with the applicable stock option plan.  Any executive bonus payments
and any incentive stock grants are subject to achieving certain performance
factors as set from time to time by management including revenue, earnings,
customer satisfaction and individual performance criteria.  However, these
incentive programs may be amended or discontinued at any time.
<PAGE>

     With respect to any stock option grants made to you by the Company or
Entrust, either before or after Closing, you shall be entitled to 100% vesting
of the options granted under the Company plan being assumed by Entrust
Technologies upon closing and 50% vesting of the stock options granted under any
Entrust stock option plan (other than the assumed Company plan) if you are
terminated or constructively terminated other than for cause within one year of
the Closing (or such greater amount of accelerated vesting as is provided for
under the relevant option plan and agreement).

     You will also be eligible to accrue three weeks of paid vacation per year
of your employment.  In addition, Entrust will recognize your vacation accrued
before Closing from the Company.  All vacation accrual will be subject to the
limits on accrual set forth in the Company employment plan.

     Upon Closing your benefit plan will continue with the Company as disclosed
in the Merger Agreement; however, it is our intention to include you in the
Entrust Technologies Inc. benefit plans as soon as practicable.  You will be
credited with your service with the Company for purposes of determining your
benefits eligibility and levels.  If you are transferred to Entrust benefit
plans other than at the end of a Company plan year, you will receive a credit
toward all deductible and co-payment limits in the Entrust medical, dental and
vision plans for payments made by you under the Company's similar plans in the
same plan year.

     With the exception of the provisions above regarding the conversion of the
stock options granted to you by the Company, Entrust may modify, revoke, suspend
or terminate any of the terms and conditions referenced herein, including the
terms, plans, policies and/or procedures adopted by the Company in respect of
the benefit plan, in whole or part, at any time, with or without notice.

     As with most other employees, your employment will be at-will.  That means
that your terms and conditions of employment, including but not limited to
termination, demotion, promotion, transfer, compensation, benefits, duties and
location of work may be changed with or without cause, for any or no reason, and
with or without notice.  Your status as an at-will employee cannot be changed by
any statement, promise, policy, course of conduct, in writing or manual except
through a written agreement signed by the CEO of Entrust.  Notwithstanding the
foregoing, in the event of termination of your at-will employment by the Company
or by Entrust of your employment without cause or a constructive termination
occurring within two years of the Closing) you shall be entitled to a severance
payment equal to six months base salary including bonus (calculated using your
target bonus and the same company performance factor as other executive
employees for the same bonus period).  Also, the Company will either provide to
you benefits during the severance period or make payments on your behalf for
benefits pursuant to COBRA during the severance period.

     This employment offer is contingent upon you signing and returning with
your offer letter the attached Intellectual Property and Confidentiality
Agreement, (the "IP Agreement").  By accepting this offer of employment at will,
you also agree to any terms and conditions contained in that document as
written.  Notwithstanding the foregoing, if you have already entered in an
agreement or agreements with the Company to substantially the same effect as the
IP Agreement,
<PAGE>

you need not execute them and the IP Agreement and its content will not be
included in this offer of employment.

     With the exception of the agreements covering stock options granted to you
by the Company prior to Closing pursuant to which vesting accelerates upon
termination of employment, this agreement supersedes any and all prior
employment agreements you have with enCommerce.

     To accept and confirm your start date, or to decline this offer, please
sign and return the original offer letter along with all other required
documentation to me before your first day of employment, which is expected to be
as of the Closing Date.  Any questions you may have should be directed to me.

                                        Sincerely,

                                        /s/ John Ryan

                                        John Ryan
                                        President and CEO

I have read, understood, and therefore,
accept this offer of employment, as set
forth above, and will report on         2000.
