                                                                 EXHIBIT (d)(12)

                    EMPLOYMENT AND NON-COMPETITION AGREEMENT

            This EMPLOYMENT AGREEMENT (this "Agreement") is made as of the 20
day of February, 2001 by and between SYBASE, INC., a Delaware corporation
("Sybase"), and FRED HORN, an individual residing at Denver, Co. (the
"Employee").

                                   BACKGROUND

            The Employee is a shareholder of [NEON] and is employed by [NEON].
Sybase and [NEON] have entered into an Agreement And Plan of Reorganization
dated of even date herewith (the "Merger Agreement") which requires, among other
things, that the Employee enter into this Agreement as part of the merger
described in the Merger Agreement (the "Merger"). This Agreement is to be
effective only upon the Effective Date (as defined in the Merger Agreement) at
which time Sybase will assign all of its rights and obligations under this
Agreement to the Surviving Corporation (as defined in the Merger Agreement).
Sybase wishes to secure on behalf of the Surviving Corporation the services of
the Employee upon the terms and conditions hereinafter set forth, and the
Employee wishes to render such services to the Surviving Corporation upon the
terms and conditions hereinafter set forth.

            NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants herein contained and for other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties agree as
follows:

1)    EMPLOYMENT BY THE SURVIVING CORPORATION. Sybase agrees to employ the
      Employee as Vice President of the e-business Platform Division and the
      Employee accepts such employment and agrees to perform such duties as are
      consistent with his title and position. Employee's duties shall be those
      customarily performed by a person holding the same title at a company of
      similar size and industry as the Surviving Corporation, and he shall
      report directly to the Pat Fortune of the Surviving Corporation. The
      Employee agrees to devote his full business time to the business of the
      Surviving Corporation and/or its Affiliates and to faithfully, diligently
      and competently perform his duties hereunder.

2)    TERM OF EMPLOYMENT. The Term of this Agreement shall commence on the
      Effective Date and continue until terminated as set forth herein. The
      parties agree that Employee's employment will be "at will" employment and
      may be terminated at any time with or without cause or notice. Employee
      understands and agrees that neither his job performance nor promotions,
      commendations, bonuses or the like give rise to or in any way serve as the
      basis for modification, amendment or extension, by implication or
      otherwise, of his employment hereunder.

3)   COMPENSATION. As compensation for all services to be rendered by the
     Employee to the Surviving Corporation and/or its Affiliates in all
     capacities during the Term, the Employee shall receive the following
     compensation and benefits:

     a)  SALARY. An annual base salary of ($300,000) (the "Base Salary"), less
         required withholdings, which shall be paid on a regular basis in
         accordance with the Surviving Corporation's normal payroll procedures
         and policies.

     b)  BONUS. The Employee shall be eligible to receive bonuses in accordance
         with such bonus plans as are applicable to employees of the Surviving
         Corporation from time to time. For calendar year 2001, the targeted
         bonus is $120,000 less required withholdings (which bonus shall only be
         payable to the extent earned under the terms of the applicable bonus
         plan).

     c)  PARTICIPATION IN EMPLOYEE BENEFIT PLANS. The Employee shall be
         permitted during the Term, if and to the extent eligible, to
         participate in all employee benefit plans, policies and practices now
         or hereafter maintained by or on behalf of the Surviving Corporation
         for employees having positions with the Surviving Corporation
         commensurate with the Employee's position with the Surviving
         Corporation. Nothing in this Agreement shall preclude the Surviving
         Corporation from terminating or amending any such plans or coverage so
         as to eliminate, reduce or otherwise change any benefit payable
         thereunder, so long as such change similarly affects all Surviving
         Corporation employees having positions with the Surviving Corporation
         that are commensurate with the Employee's position with the Surviving
         Corporation.

     d)  EXPENSES. The Surviving Corporation shall pay or reimburse the Employee
         for all reasonable expenses actually incurred or paid by the Employee
         during the Term in the performance of the Employee's duties under this
         Agreement, upon submission and approval of expense statements, vouchers
         or other supporting information, in accordance with the then customary
         practices of the Surviving Corporation.

     e)  VACATION. The Employee shall be entitled to vacation in accordance with
         Sybase policy.

     f)  WITHHOLDING OF TAXES. The Surviving Corporation may withhold from any
         compensation payable under this Agreement all federal, state, city and
         other taxes as shall be required pursuant to any law or governmental
         regulation or ruling.

     g)  STOCK OPTIONS. The Surviving Corporation shall grant to Employee stock
         options (the "Employee Option") to acquire up to 125,000 shares of
         Sybase, Inc common stock. The stock options granted to Employee shall
         vest such that 1/8th of such option shares shall vest six months after
         the Effective Date and 1/48th of such option shares shall vest each
         month thereafter through the 48th month after the Effective Date.
         Otherwise, the stock


Page 2

          options granted will be upon the same terms and conditions as are
          generally provided under the Sybase, Inc. Stock Plans.

4)   TERMINATION.

     a)   TERMINATION UPON DEATH. If the Employee dies during the Term, this
          Agreement shall terminate as of the date of his death.

     b)   TERMINATION UPON DISABILITY. If, during the Term, the Employee
          becomes physically or mentally disabled, the Surviving Corporation
          may, by written notice to the Employee, terminate this Agreement, in
          which event the Term shall terminate 30 days after the date upon
          which the Surviving Corporation shall have given notice to the
          Employee of its intention to terminate this Agreement because of such
          disability. Disability shall be determined in accordance with the
          terms of the applicable policies and benefit plans of the Surviving
          Corporation.

     c)   TERMINATION FOR CAUSE. The Surviving Corporation may at any time by
          written notice to the Employee terminate this Agreement immediately,
          and the Employee shall have no right to receive any compensation or
          benefit hereunder on and after the date of such notice, in the event
          that an event of "Cause" occurs. For purposes of this Agreement
          "Cause" shall mean:

          (i)   the continuous failure by the Employee to perform the material
                duties and responsibilities that are reasonably consistent with
                his position which remain uncured for a period of fifteen (15)
                days after receipt of notice thereof from the Surviving
                Corporation;

          (ii)  a conviction of, a plea of nolo contendere, a guilty plea or
                confession by the Employee to a felony or the committing of an

                embezzlement, theft or misappropriation of property belonging
                to, the Surviving Corporation or its Affiliates;

          (iii) the Employee personally engaging in conduct that he reasonably
                should know or that he intends to be seriously injurious to the
                business of the Surviving Corporation or its Affiliates (it
                being understood that business decisions made by the Employee
                in good faith are not to be considered grounds for termination
                for Cause); or

          (iv)  the material breach by the Employee of this Agreement or the
                Nondisclosure and Assignment of Inventions Agreement which is
                not cured within fifteen (15) days after receipt of notice
                thereof from the Surviving Corporation (except for a breach of
                Section 7 hereof or a breach of the Nondisclosure and Assignment
                of Inventions Agreement for which no cure period is provided).

      d)    TERMINATION WITHOUT CAUSE. The Surviving Corporation may terminate
            this Agreement at any time, without cause, and the Employee shall
            have no right to receive any compensation or benefit hereunder
            after such termination except as set forth in Section 5 below.
            Employee may terminate this Agreement without cause, and the
            Employee shall have no right to receive any compensation or benefit
            hereunder after such termination.

      e)    SURRENDER OF RECORDS AND PROPERTY. Upon termination of his

            promptly to the Surviving Corporation all property and all tangible
            forms of Confidential Information in accordance with the terms of
            the Nondisclosure and Assignment of Inventions Agreement between
            Sybase and the Employee.

5)    SEVERANCE PAYMENTS AND OTHER RIGHTS.

      a)    CERTAIN SEVERANCE PAYMENTS AND OTHER RIGHTS. If, during the Term,
            the Surviving Corporation terminates this Agreement pursuant to
            Section 4(d), all compensation payable to the Employee under
            Section 3 shall cease as of the date of termination specified in
            the Surviving Corporation's notice (the "Termination Date"), and
            the Surviving Corporation shall pay or provide to the Employee the
            following, provided that the Employee first enters into and does
            not revoke a binding written agreement releasing all claims, known
            or unknown, that the Employee has or might have against the
            Surviving Corporation in connection with this Agreement and other
            employment arrangements with the Surviving Corporation and its
            Affiliates and for wrongful discharge, and provided further that
            the Employee has not violated the terms of Section 7 of this
            Agreement. (Payment of the severance payments does not constitute
            an acknowledgement by the Surviving Corporation of the Employee's
            compliance with the terms of Section 7.) All severance payments
            shall be subject to applicable tax withholding, and shall be in
            lieu of any further payments under this Agreement or under any
            other employment arrangements between the Employee and the
            Surviving Corporation.

            (i)   a lump sum amount equal to the VP severance package then
                  applicable to employees;

            (ii)  for a period equal to the earlier of 24 mos or (y) the date
                  upon which Employee and his covered dependents become covered

                  payment of applicable premiums under COBRA for group health
                  coverage in order to provide the Employee and his covered
                  dependents equivalent coverage to that which they were
                  entitled to while Employee was an employee of the Surviving
                  Corporation immediately prior to his termination; and

            (iii) all previously accrued vacation pay.

     b)   PAYMENTS UPON TERMINATION FOR CAUSE, DEATH OR DISABILITY. If this
          Agreement is terminated by the Surviving Corporation pursuant to
          Sections 4(a), 4(b) or 4(c), the Employee shall receive only the
          amounts owing through the Termination Date.

6)   REPRESENTATION AND WARRANTY OF EMPLOYEE. The Employee represents and
     warrants that neither the execution nor the delivery of this Agreement, nor
     the employment of the Employee by the Surviving Corporation will result in
     the breach of any agreement to which the Employee is a party, except where
     any such breach would not have a material adverse effect on the business,
     financial condition or operations of the Surviving Corporation.

7)   COVENANTS. The Employee acknowledges that: (i) he is one of the limited
     number of persons who will develop the business of the Surviving
     Corporation; (ii) his work for the Surviving Corporation has brought him
     and will continue to bring him into close contact with many confidential
     affairs not readily available to the public; and (iii) the covenants
     contained in this Section 7 will not involve a substantial hardship upon
     his future livelihood. In light of such acknowledgement, and in partial
     consideration of the several agreements made by Sybase with the Employee in
     the Merger Agreement and in order to induce the Surviving Corporation to
     enter into this Agreement and the Merger Agreement, the Employee covenants
     and agrees that:

     a)   NON-COMPETE. During the period of his employment by the Surviving
          Corporation under this Agreement and for 18 months following the
          termination, of the Employee's employment for any reason, provided the
          Surviving Corporation is not in breach of its obligations under
          Section 5, the Employee shall not, directly or indirectly: (i) in any
          manner whatsoever engage in any capacity with any Restricted Business
          in a Restricted Territory (as such terms are defined below) for the
          Employee's own benefit or for the benefit of any Person other than the
          Surviving Corporation; or (ii) have any interest as owner, sole
          proprietor, shareholder, partner, lender, director, officer, manager,
          employee, consultant, agent or otherwise in any Restricted Business in
          a Restricted Territory; provided, however, that the Employee may hold,
          directly or indirectly, solely as an investment, not more than two
          percent (2%) of the outstanding securities of any person or entity
          which are listed on any national securities exchange or regularly
          traded in the over-the-counter market notwithstanding the fact that
          such person or entity is a Restricted Business in a Restricted
          Territory.

          "Restricted Business" shall mean (A) a business which is competitive
          with the Surviving Corporation's business engaged in by the Surviving
          Corporation at the date of his termination of employment (the
          "Surviving Corporation's Business") and (B) Oracle Systems
          Corporation, Informix Corporation, the database product groups or
          organizations of Computer Associates, the database product groups or
          organizations of Microsoft Corporation and the database product groups
          or organizations of IBM. Notwithstanding the above, the Employee may
          become an employee of or consultant to or have an interest as owner,
          sole proprietor, shareholder, partner, lender, director, officer,
          manager,

Page 5
   6
          employee, consultant, agent or otherwise in a business unit of a
          larger enterprise which enterprise then has another business unit
          engaged in a business competitive with the Surviving Corporation's
          Business, provided that the business unit of the larger enterprise for
          which Employee provides services or in which he has an interest is
          neither (1) in a business competitive with the Surviving Corporation's
          Business and is located in a geographically separate location from the
          competitive business unit and the Employee has no responsibility and
          has no role whatsoever in the competing business unit nor (2) a
          company or business unit listed in clause B of this paragraph.

          "Restricted Territory" shall mean the larger of (i) the counties,
          cities and states of the United States of America and each political
          subdivision of Canada, Australia, Japan, each member of the European
          Economic Community and any other country in which the Surviving
          Corporation's products are sold or licensed during the term of the
          non-compete obligations or (ii) if (i) is found unenforceable, the
          counties, cities, states and political subdivisions of any country in
          which the Surviving Corporation's products are sold, distributed or
          licensed during the term of the non-compete obligations.

          The parties intend that the covenants contained in this Section 7(a)
          shall be construed as a series of separate covenants, one for each
          county, city, state and other political subdivision of each country in
          the Restricted Territory. Except for geographic coverage, each
          separate covenant shall be deemed identical in terms to the covenant
          contained in the preceding paragraphs. If, in any judicial proceeding,
          a court shall refuse to enforce any of the separate covenants (or any
          part thereof) deemed included in said paragraphs, then such
          unenforceable covenant (or such part) shall be deemed eliminated from
          this Agreement for the purpose of those proceedings to the extent
          necessary to permit the remaining separate covenants (or portions
          thereof) to be enforced by such court. It is the intent of the parties
          that the covenants set forth herein be enforced to the maximum degree
          permitted by applicable law.

          In the event that the provisions of this Section 7(a) should ever be
          deemed to exceed the scope, time or geographic limitations of
          applicable law regarding covenants not to compete, then such
          provisions shall be reformed to the maximum scope, time or geographic
          limitations, as the case may be, permitted by applicable laws.

     b)   NON-DISCLOSURE OF CONFIDENTIAL INFORMATION. Concurrently with the
          execution of this Agreement, the Employee shall enter into a
          Nondisclosure And Assignment of Inventions Agreement in the form
          attached hereto.

     c)   NON-SOLICITATION OF EMPLOYEES OF AND CONSULTANTS TO THE SURVIVING
          CORPORATION. During the period of his employment by the Surviving
          Corporation under this Agreement and for 18 months following the
          termination of the Employee's employment for any reason, the Employee
          shall not, directly or indirectly, initiate communications with,
          solicit, persuade, entice, induce or encourage any individual who is
          then or who has been within


Page 6
   7
     the preceding 12-month period, an employee of or consultant to the
     Surviving Corporation to terminate an employment or consulting relationship
     with the Surviving Corporation, as the case may be, or to become employed
     by or enter into a contract or other agreement with any other person, and
     the Employee shall not approach any such employee or consultant for any
     such purpose or authorize or knowingly approve the taking of any such
     actions by any other person.

d)   NON-SOLICITATION OF CUSTOMERS. During the period of his employment by the
     Surviving Corporation under this Agreement and for 18 months following the
     termination of the Employee's employment for any reason, the Employee shall
     not, directly or indirectly, solicit, persuade, entice, induce, encourage
     (or assist in connection with any of the foregoing) any person who is then
     or has been within the preceding 24-month period a customer or account of
     the Surviving Corporation, or any infomediary, affiliate, service provider
     or fulfillment entity that does business with the Surviving Corporation, or
     any actual customer leads whose identity the Employee learned during the
     course of his employment with the Surviving Corporation, to terminate or to
     adversely alter its contractual or other relationship with the Surviving
     Corporation.

e)   RIGHTS AND REMEDIES UPON BREACH. If the Employee breaches, or threatens to
     commit a breach of, any of the provisions of this Section 7 (collectively,
     the "Restrictive Covenants"), the Surviving Corporation shall have the
     right and remedy to seek from any court of competent jurisdiction specific
     performance of the Restrictive Covenants or injunctive relief against any
     act which would violate any of the Restrictive Covenants, it being
     acknowledged and agreed that any such breach or threatened breach will
     cause irreparable injury to the Surviving Corporation and that money
     damages will not provide an adequate remedy to the Surviving Corporation.

f)   REPRESENTATION OF THE EMPLOYEE. The Employee is (i) familiar with the
     covenants in this Section 7, (ii) is fully aware of his obligations
     hereunder, (iii) finds the length of time, scope and geographic coverage of
     these covenants to be reasonable, and (iv) is receiving specified,
     bargained-for consideration for these covenants.

8)   MISCELLANEOUS.

                corporation, association, joint stock Surviving Corporation,
                trust, joint venture, unincorporated organization, institution,
                entity or government (whether federal, state, local or otherwise
                including without limitation, or any department, agency, or
                political subdivision thereof).

     g)   COUNTERPARTS; FACSIMILE EXECUTION. This Agreement may be executed in
          two or more counterparts, each of which shall be deemed an original
          but all of which together shall constitute one and the same
          instrument. Facsimile execution and delivery of this Agreement is
          legal, valid and binding execution and delivery for all purposes.

     h)   HEADINGS. The headings in this Agreement are for reference purposes
          only and shall in no way affect the meaning or interpretation of this
          Agreement.

     i)   SURVIVAL. Sections 4(e),5,6,7 and this Section 8 shall survive
          termination of this Agreement for any reason.

     j)   SEVERABILITY. To the extent any provision of this Agreement shall be
          invalid or unenforceable, it shall be considered deleted herefrom and
          the remainder of such provision and of this Agreement shall be
          unaffected and shall continue in full force and effect. In furtherance
          and not in limitation of the foregoing, should the duration of
          geographical extent of, or business activities covered by any
          provision of this Agreement be in excess of that which is valid and
          enforceable under applicable law, then such provision shall be
          construed to cover only that duration, extent or activities which may
          validly and enforceably be covered.

     k)   ADR. Except as provided herein, no civil action with respect to any
          dispute, claim or controversy arising out of or relating to this
          agreement may be commenced until the matter has been submitted to
          JAMS/ENDISPUTE, or its successor, for mediation. Either party may
          commence mediation by providing to JAMS/ENDISPUTE and the other party
          a written request for mediation, setting forth the subject of the
          dispute and the relief requested. The parties will cooperate with
          JAMS/ENDISPUTE and with one another in selecting a mediator from
          JAMS/ENDISPUTE's panel of neutrals, and in scheduling the mediation
          proceedings. The parties covenant that they shall participate in the
          mediation in good faith, and that they shall share equally in its
          costs. All offers, promises, conduct and statements, whether oral or
          written, made in the course of the mediation by any of the parties,
          their agents, employees, experts and attorneys, and by the mediator
          and any JAMS/ENDISPUTE employees, are confidential, privileged and
          inadmissible for any purpose, including impeachment, in any litigation
          or other proceeding involving the

     parties, provided that evidence that is otherwise admissible or
     discoverable shall not be rendered inadmissible or non-discoverable as a
     result of its use in the mediation. Either party may seek equitable relief
     prior to the mediation to preserve the status quo pending the completion of
     that process. Except for such an action to obtain equitable relief, neither
     party may commence a civil action with respect to the matters submitted to
     mediation until after the completion of the initial mediation session, or
     45 days after the date of filing the written request for mediation,
     whichever occurs first. Mediation may continue after the commencement of a
     civil action, if the parties so desire. The provisions of this Clause may
     be enforced by any Court of competent jurisdiction, and the party seeking
     enforcement shall be entitled to an award of all costs, fees and expenses,
     including attorneys fees, to be paid by the party against whom enforcement
     is ordered.

l)   SUPERCEDES OLD AGREEMENTS. Employee agrees that the terms of this Agreement
     supercede the terms of any and all employment arrangements he may have had
     with the Surviving Corporation in their entirety (except that that certain
     Agreement dated 2/16/01, 2001 shall survive). Employee agrees that
     Employee's decision to terminate such employment arrangements and enter
     into this Agreement does not constitute constructive termination of any
     employment arrangement Employee had with [NEON].

m)   COSTS OF ENFORCEMENT OR DEFENSE. In the event of any litigation with
     respect to this Agreement, the prevailing party shall be entitled to be
     paid by the other party hereto all costs of enforcement or defense, as the
     case may be, paid or incurred in connection with the enforcement or
     defense, including reasonable attorney fees and legal costs.

n)   DELAYS OR OMISSIONS. No delay or omission to exercise any right, power or
     remedy accruing to either party upon any breach or default of the other
     party hereto shall impair any such right, power or remedy of such
     non-defaulting party, nor shall it be construed to be a waiver of any such
     breach or default or an acquiescence therein, or of or in any similar
     breach or default thereafter occurring; nor shall any waiver of a breach or
     default be deemed to be a waiver of any other breach or default.

o)   RULES OF CONSTRUCTION. Sybase and the Employee each acknowledge that they
     have been represented by competent counsel during the negotiation and
     execution of this Agreement and therefore waive the application of any law,
     regulation, holding or rule of construction providing that ambiguities in
     any agreement will be construed against the party drafting the agreement.

p)   CLOSING. This Agreement shall become effective at the time of the Closing
     on the Effective Date.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.
