                    MASTER TECHNOLOGY DEVELOPMENT AGREEMENT


     This Master Technology Development Agreement is entered into as of the 14
day of October, 1997, by and between fonix corporation, a corporation of the
State of Delaware having its principal place of business located at 1225 Eagle
Gate Tower, 60 East South Temple Street, Salt Lake City, Utah 84111 ("fonix"),
and Oregon Graduate Institute of Science and Technology, a non-profit
corporation and educational institution duly organized and existing under the
laws of the State of Oregon, with its principal place of business located at
20000 N.W. Walker Road, Beaverton, Oregon  97291-1000 ("OGI"), acting through
its Oregon Graduate Institute of Science and Technology, Center for Spoken
Language Understanding ("CSLU").

1.   Purpose and Scope of Agreement

     fonix is engaged in research and development of automatic speech
recognition technologies, which technologies employ a proprietary phonetic
speech modeling engine and a linguistic and contextual process based on a
proprietary neural network system.  CSLU is a center at OGI which has a
professional staff and graduate students with special training and research
skills in spoken language disciplines and which is also engaged in research and
development of automatic speech recognition technologies.  fonix desires OGI to
perform certain development activities in order to develop and improve advanced
technologies in key areas of spoken language systems, which may include:  (a)
robust speech recognition; (b) natural language understanding; (c) dialog
modeling; (d) text-to-speech synthesis; (e) multi-modal input/output; and (f)
advanced neural net architectures.

     Therefore, from time to time fonix agrees to sponsor OGI, acting through
its CSLU, to perform work regarding certain concepts concerning the design and
implementation of spoken language computer systems and OGI agrees to provide the
results to fonix in accordance with the terms and conditions of this Agreement.

2.   Organization

     This Agreement contains terms and conditions for all work transactions
between fonix and OGI involving OGI's CSLU that are within the scope of this
Agreement.  fonix and OGI intend that all individual work transactions that are
within the scope of this Agreement will be implemented through the individual
Statements of Work to be attached hereto as Exhibit A-1, A-2, A-3 and so on, as
they are mutually agreed to by the parties.  As the parties identify future
development projects, they will execute Statements of Work, consecutively
numbered and attached to this Agreement.

7.   Confidentiality and Information Exchange

     It is the intention of OGI and fonix to transfer and/or exchange
information, including Confidential Information, as may be necessary under the
Statements of Work. Such information may be disclosed in oral, visual, or
written form (including magnetic media).

     7.1  The Recipient of Confidential Information under a Statement of Work
          shall make use of the Confidential Information only for the purposes
          of that Statement of Work and for no other purpose.

     7.2  The Recipient shall protect the disclosed Confidential Information by
          using the same degree of care, but no less than a reasonable degree of
          care, to prevent the unauthorized use, dissemination, or publication
          of the Confidential Information as the Recipient uses to protect its
          own Confidential Information of a like nature. Such protection shall
          include, at a minimum, that all fonix and OGI individuals working on
          any Statement of Work shall execute and deliver to the other party a
          blanket non-disclosure agreement in the form attached hereto as
          Exhibit B. Such non-disclosure agreement shall require OGI and fonix
          personnel not to disclose information relating to, concerning or in
          any fashion resulting from the Statement of Work to a third party
          without the prior written approval of fonix.

     7.3  Except as set forth in Section 7.4 below, the Recipient's obligations
          shall only extend to Confidential Information that is marked as
          confidential at or before the time of disclosure or that is unmarked
          (e.g., orally disclosed) but is treated as confidential at the time of
          disclosure and is designated as confidential in a written memorandum
          sent to the Recipient's Project Manager within thirty (30) days of
          disclosure, summarizing the Confidential Information sufficiently for
          identification.
 
     7.4  Without written notice of confidentiality at any time subsequent
          hereto, OGI agrees to treat all Code and related system documentation
          received under a Statement of Work (or developed from Source Code
          received under a Statement of Work) as confidential information for
          the purposes of this Section 7. OGI agrees not to reverse engineer the
          binary code of fonix to discover the Source Code.

     7.5  The parties hereby acknowledge that a party's unauthorized disclosure
          or use of Confidential Information belonging to the other party will
          cause substantial and irreparable injury to the other party, and that
          each party is therefore entitled to, in addition to any other
          available remedies, injunctive and other equitable relief for any
          actual or threatened improper disclosure or use of its Confidential
          Information.

          interest in and to such Derivative Works and shall execute any
          documents reasonably requested by OGI to evidence or perfect such
          assignment. OGI grants to fonix a nonexclusive, worldwide, royalty-
          free, fully-paid and irrevocable license under copyrights and patents
          arising out of such Derivative Works to use internally and/or
          externally, sell, license, lease or otherwise transfer such Derivative

<PAGE>
 
          shall execute any documents reasonably requested by fonix to evidence
          or perfect such assignment. fonix grants to OGI a nonexclusive,
          worldwide, royalty-free, fully-paid, irrevocable and nontransferable
          license under copyrights and patents arising out of such Derivative
          Works to use such in its Toolkit, as more fully described in Section
          8.5. fonix shall also solely own all right, title and interest in and
          to all Derivative Works of the Technology prepared, developed or
          created by fonix or pursuant to its direction, without substantial
          participation of OGI.

     8.4  Patent Immunity. Subject to Section 8, each party grants to the other
          party, and recipients of Deliverables leased, licensed, sold or
          otherwise transferred (either directly or indirectly) by such other

          Toolkit" which it has and does make available to its members for use
          in designing and developing spoken language products. In addition to
          use of Intellectual Property Rights in the Technology and Joint
          Inventions (which may be freely used by either party, as stated in
          Section 8.1 above), CSLU may incorporate Derivative Works of fonix (as
          described in the first sentence of Section 8.3 hereof) into its
          Toolkit only for non-commercial use and application. In that regard,
          CSLU shall take such steps as are necessary and to the reasonable
          satisfaction of fonix to prevent any CSLU member from gaining access
          to or otherwise using any Derivative Works of fonix for commercial
          purposes.

     8.6  Freedom of Use. Notwithstanding anything to the contrary set forth in
          this Agreement (but expressly excluding the limitations and
          restrictions set forth in Section 8.3 hereof), either party shall be
          free to use for any purposes the Residuals resulting from access to or
          work with Confidential Information. However, the foregoing does not
          give either party the right to disclose the financial, statistical, or
          personnel information or the business plans of the other party, and
          the foregoing shall not be deemed to grant to either party a license
          under the other party's copyrights or patents. Neither party shall
          have any obligation to limit or restrict the assignment or
          reassignment of personnel.

     8.7  Survival. This Section 8 and related definitions shall survive the
          termination of this Agreement for any reason whatsoever.

10.  Limited Warranty

     10.1 OGI represents and warrants that it either is the owner of all rights,
          title and interests, including Intellectual Property Rights, in the
          Technology, or that it has the right to use and sublicense the use of
          the Technology in accordance with the terms and conditions set forth
          in this Agreement. OGI makes no representation that the duplication,
          use, lease, sale, license or sublicense of the Technology by fonix
          will not infringe a copyright or patent granted to others. However,
          OGI does represent and warrant that it shall take reasonable and
          necessary steps to avoid contamination of the Technology with the
          intellectual property rights of third parties by requiring each
          participating Project Manger to complete in good faith an Intellectual
          Property Rights Questionnaire in the form attached hereto as Exhibit
          C, for delivery to fonix at the completion of the research identified
          in the Statements of Work.

     10.2 fonix represents and warrants that, to the best of its knowledge, it
          either is the owner of all rights, title and interests including
          Intellectual Property Rights in any technology which it may provide to
          OGI under this Agreement, or that it has the right to use and
          sublicense the use of such technology in accordance with the terms and
          conditions set forth in this Agreement. fonix makes no representation
          that the duplication, use, lease, sale, license or sublicense of the
          Technology by OGI will not infringe a copyright or patent granted to
          others.

     10.3 THE WARRANTIES AND REPRESENTATIONS SET FORTH IN SECTION 10 AND 11 OF
          THIS AGREEMENT ARE EXPRESSLY IN LIEU OF ALL OTHER UNDERSTANDINGS,
          AGREEMENTS, REPRESENTATIONS OR WARRANTIES NOT EXPRESSLY SET FORTH IN
          THIS AGREEMENT, WHETHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED
          TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
          PARTICULAR PURPOSE.

11.  Limitation of Liability

     Under no circumstances shall either party be liable to the other for any
indirect or consequential damages whatsoever, including, but not limited to,
loss of profits or for any claim or demand made by a third party against either
party arising out of the performance of this Agreement, except as specifically
set forth in Section 12.  No action, regardless of form, arising out of the
performance of this Agreement, may be brought by either party more than four (4)
years after the cause of action is discovered.

12.  Product Liability and General Indemnification.

     12.1 OGI does not warrant the Technology and the parties to this Agreement
          agree and understand that OGI shall have no liability to an end user
          or otherwise. fonix, therefore, agrees to hold OGI harmless and
          indemnify OGI, its trustees, officers, employees and agents from and
          against any and all litigation, claims, damages or actions (including
          reasonable attorney's fees) that may be

                                       10
<PAGE>
 
          instituted against OGI arising out of fonix's marketing, distribution,
          sale, production, manufacture, lease, consumption or advertisement of
          the Technology including, but not limited to, claims resulting from
          any alleged type of defect in the Technology or damages allegedly
          caused by any breach of contract by fonix and its affiliates or the
          use or misuse of the Technology, notwithstanding any third-party
          allegation that their claims, injuries or damages were proximately
          caused in part or wholly by OGI's negligence. In such event, fonix
          agrees to defend OGI at fonix's sole expense in such action. Should
          any award or decree be made against OGI, it shall be the obligation of
          fonix to (a) appeal the decision and pay if the appeal is lost or (b)
          pay such award or make any settlement as may be warranted before or
          after the decision on appeal. OGI may, at its own option, conduct its
          own defense in such actions at its own expense.

     12.2 fonix does not warrant the technology, services or materials provided
          to OGI pursuant to this Agreement. OGI, therefore, agrees to hold
          fonix harmless and indemnify fonix, its trustees, officers, employees
          and agents from and against any and all litigation, claims, damages or
          actions (including reasonable attorney's fees) that may be instituted
          against fonix arising out of OGI's use, marketing, distribution, sale,
          production or licensing (non-commercial or otherwise) of the
          Technology including, but not limited to, claims resulting from any
          alleged type of defect in the Technology or damages allegedly caused
          by any breach of contract by OGI or the use or misuse of the
          Technology, notwithstanding any third-party allegation that their
          claims, injuries or damages were proximately caused in part or wholly
          by fonix's negligence. In such event, OGI agrees to defend fonix at
          OGI's sole expense in such action. Should any award or decree be made
          against fonix, it shall be the obligation of OGI to (a) appeal the
          decision and pay if the appeal is lost or (b) pay such award or make
          any settlement as may be warranted before or after the decision on
          appeal. fonix may, at its option, conduct its own defense in such
          actions at its own expense.

     12.3 Each party's indemnification obligations are subject to (a) receipt of
          prompt notice such that the indemnifying party will not be unduly
          prejudiced by any delay, and (b) the good faith cooperation of the
          party to be indemnified. Each party shall immediately notify the other
          of any litigation in which it, its officers or its directors, agents
          or employees may be involved if there is a reasonable possibility that
          this Agreement or the other party will be affected. The parties agree
          to cooperate with each other and keep each other fully informed with
          respect to all proceedings.

13.  Delivery of Technology

     OGI shall fully disclose and deliver to fonix all Technology arising out of
the work, development, research and experimentation conducted by OGI under this
Agreement, as implemented in Statements of Work.  The Technology delivered to
fonix under this Agreement shall be in such forms as shall be necessary for
fonix to make, install, operate, modify, correct, enhance and extend the
Technology.

                                       11
<PAGE>
 
14.  Disclosure of this Agreement

     Neither party shall refer to or use the name of the other party in any
publication, news release or promotion without the prior consent of the other
party.  Each party shall use best efforts not to disclose to any third party the
terms and conditions of this Agreement during its Term, except as required by
law, or by order of a court of competent jurisdiction, or as may be required to
establish or assert its rights hereunder.  Notwithstanding the above, fonix
hereby grants the right and encourages OGI to refer to fonix in OGI's
publications as a sponsor of the work conducted under this Agreement.

15.  Independent Development

     Nothing contained in this Agreement shall prevent fonix from entering into
research projects with third parties which are similar to the development or
other work which is the subject of this Agreement, or from independently
developing (either through third parties or through the use of its own
personnel), or from acquiring from third parties, technologies or products which
are similar to and competitive with Technology.  Nothing herein shall be
construed to grant OGI any rights in any such technologies or products so
developed or acquired, or any rights to the revenues or any portion thereof
derived by fonix from the use, sale, lease, license or other disposal of any
such technologies or products.  Furthermore, nothing herein shall preclude fonix
from transferring any such technologies or product to others.

     Neither OGI nor any person working on the Statement of Work as an employee,
contractor or agent of OGI shall  enter into any projects with any third
parties, excepting federal, state or local governmental units or agencies, the
results of which may reasonably be anticipated to have a material harmful effect
upon the Inventions, Intellectual Property Rights and/or business prospects of
fonix, during the term hereof or for eighteen (18) months thereafter.  In the
event that OGI desires to engage in a project which may violate the covenant set
forth in the previous sentence, OGI shall promptly give notice thereof to fonix
in detail sufficient for fonix to analyze the basis whereby OGI believes that
said research project may have a material harmful effect upon fonix.  fonix
shall promptly review the notice and all accompanying material supplied by OGI.
OGI covenants and agrees that it will not enter into the proposed research
project if fonix determines that the proposed research project would violate the
covenant set forth in the first sentence of this section.  fonix shall not
unreasonably withhold its approval of any proposed third party project.

16.  Taxes

     OGI shall pay all taxes, if any, arising from the consideration paid by
fonix to OGI.  Each party shall otherwise be responsible for and shall pay all
other taxes arising solely from its performance under this Agreement.

17.  Personal Services

     17.1 By OGI Coordinator. During the Term, OGI shall cause the OGI
          Coordinator to render personal services (a) in various industry
          programs, seminars and similar events annually to be scheduled
          mutually with fonix. The OGI Coordinator will appear as a

                                       12
<PAGE>
 
          representative of CSLU and/or fonix, as mutually agreed by OGI and
          fonix, for the purpose of promoting, discussing and/or endorsing the
          Technology; and (b) at various presentations of papers or articles
          concerning the Technology prepared by (either individually or with
          others) the OGI Coordinator, as mutually agreed by the OGI Coordinator
          and fonix. In each case, the presentation, paper or article to be
          delivered shall be approved by fonix in advance. For such appearances,
          OGI shall be paid $500.00 per day by fonix.

     17.2 By OGI Professional Staff. During the Term, OGI shall cause members of
          its professional staff to be available to fonix pursuant to the terms
          of individual consulting agreements. Messrs. Cole and Yan shall be
          available at least two (2) days per month on terms mutually agreeable
          to those parties.

18.  DARPA Competition.  CSLU is preparing an entry for the November, 1997 "HUB4
Broadcast News" Evaluation sponsored by the Defense Advanced Research Project
Agency ("DARPA Competition").  CSLU will use its best efforts to complete its
entry for and actively participate in the DARPA Competition.  At the option of
fonix, the entry of CSLU in the DARPA Competition shall be credited jointly to
CSLU and fonix.

19.  fonix Center Membership to CSLU. fonix or an Affiliate shall make a
supplemental Center Membership payment of $200,000 corresponding to the fonix
annual membership period May 16, 1997 through May 15, 1998.  The supplemental
payment shall be paid in two (2) equal installments of $100,000, with the first
payment due on the last day of the calendar quarter after the date of execution
of this Agreement and the second payment due six (6) months thereafter.

20.  Construction.

     20.1 Order of Precedence. In the event of any conflict between this
          Agreement and a Statement of Work, the terms of the Agreement shall
          control. In the event of any conflict between this Agreement or a
          Statement of Work and any purchase order or acknowledgment, this
          Agreement or the Statement of Work shall take precedence over any
          written or typed instructions in an written or electronic purchase
          order or acknowledgment.

     20.2 Headings & Gender. The headings in this Agreement and in a Statement
          of Work are provided for reference only and shall not be used as a
          guide to interpretation. When used in this Agreement or in a Statement
          of Work, the singular includes the plural and the plural includes the
          singular, and gender related pronouns include the feminine, masculine
          and neuter.

     20.3 References. References to a specific Section of this Agreement or in a
          Statement of Work shall be deemed to include within the scope of the
          reference all subsections depending therefrom. By way of example, a
          reference to Section 5 shall be deemed to include a reference to
          Section 5.1.

     20.4 Severability. If any provision of this Agreement or a Statement of
          Work is held in arbitration or by a court of competent jurisdiction to
          be invalid, illegal or unenforceable, the remaining provisions

                                       13
<PAGE>
 
          shall remain in full force and effect and shall be interpreted, to the
          extent possible, to achieve the purpose of this Agreement and any
          affected Statements of Work as originally expressed.

     20.5 Conflict Resolution. The parties agree that with respect to any
          controversy or claim arising out of or relating to this Agreement or
          the breach of this Agreement they shall attempt in good faith to
          resolve such claim or controversy by negotiations between the parties.
          In the event that either party believes that the negotiation
          discussions are not likely to lead to settlement, the parties must
          participate in good faith in at least one mediation session with a
          professional mediator knowledgeable in the industry mutually selected
          by the parties, the expense of which shall be paid fifty percent (50%)
          by each party. With respect to disputes concerning ownership issues or
          improper disclosure or use of Confidential Information which are not
          resolved in mediation, the dispute will be resolved in a court of
          appropriate jurisdiction. After one or more mediation sessions
          involving any other issue, either party may elect to resolve the
          dispute through final and binding arbitration in Salt Lake City, Utah.
          In such case, each party shall appoint an arbitrator and a third
          arbitrator shall be appointed by mutual agreement of the two chosen
          arbitrators. All arbitrators must be knowledgeable in the software
          industry. Otherwise, the procedure governing the arbitration process
          shall be in accordance with the Rules of the American Arbitration
          Association or such other process as is mutually agreeable to the
          parties and reduced to writing. This Agreement shall be enforceable by
          law and the judgment or any award made by the arbitrators may be
          entered in any court having appropriate jurisdiction. The prevailing
          party in any arbitration or judicial action shall be entitled to its
          reasonable costs and attorneys' fees from the non-prevailing party.

     20.6 Entire Agreement. This Agreement, including the Statements of Work
          agreed to by both parties, sets forth the entire agreement and
          understanding between the parties as to its specific subject matter
          and merges all prior discussions between them with regard to such
          specific subject matter. Neither of the parties shall be bound by any
          conditions, definitions, warranties, understandings, agreements, or
          representations, whether written or oral, with respect to such
          specific subject matter other than as expressly provided herein or in
          a Statement of Work or as duly set forth on or subsequent to its
          effective date, in a written document that is signed by a duly
          authorized representative of each party.

     20.7 Governing Law. The validity, construction, and performance of this
          Agreement and the Statements of Work will be governed by the
          substantive law of the State of Utah without regard to any choice of
          law provisions. Each party shall, at its own expense, comply with any
          governmental law, statute, ordinance, administrative order, rule or
          regulation relating to its duties, obligations or performance under
          this Agreement and the Statements of Work.

21.  Independent Contractors

     Each party is and shall remain an independent contractor with respect to
all performance under this Agreement and the Statements of Work.  No employee of
either party shall be considered an employee or agent of the other party for any
purpose.  Each party assumes sole responsibility for the supervision, daily

                                       14
<PAGE>
 
direction and control, payment of salary (including withholding of income taxes
and social security), worker's compensation, disability benefits and the like of
its employees or agents.

22.  Export of Technical Data

     Neither party will knowingly export or re-export or cause to be exported or
re-exported, directly or indirectly, any materials or any items licensed or
developed under a Statement of Work or technical information or direct product
thereof received from the other party to any country for which the United States
government, or any agency thereof, requires an export license or other
government approval at the time of such export without first obtaining any
required license or approval.  Each party will reasonably cooperate with the
other party in obtaining such licenses or approvals.

23.  Notices

     All notices to a party under this Agreement or a Statement of Work shall be
delivered to that party's Coordinator at the address stated in Section 2 above.
All notices required or permitted to be given under this Agreement or a
Statement of Work shall be in writing.  A notice shall be validly given upon the
earlier of confirmed receipt by the recipient's Coordinator or seven (7) days
after deposit, postage prepaid, with the U.S. Postal Service as first class
mail. Notices may be delivered by telefax or by courier and shall be validly
given upon confirmed receipt by the recipient's Coordinator or Project Manager,
