              Notes to Condensed Consolidated Financial Statements
                                  June 30, 1997

1.  BASIS OF PRESENTATION

         The accompanying unaudited condensed consolidated financial statements
         have been prepared in accordance with generally accepted accounting
         principles for interim financial information and pursuant to the rules
         and regulations of the Securities and Exchange Commission. Accordingly,
         they do not include all of the information and footnotes required by
         generally accepted accounting principles for complete financial
         statements.

         In the opinion of management, all adjustments (consisting of only
         normal recurring adjustments) considered necessary for a fair
         presentation have been included. Operating results for the three month
         period ended June 30, 1997 are not necessarily indicative of the
         results that may be expected for the year ended March 31, 1998. For
         further information, refer to the Company's consolidated financial
         statements and notes thereto contained in the Company's Annual Report
         on Form 10-K for the year ended March 31, 1997. The year-end condensed
         balance sheet data was derived from audited financial statements, but
         does not include all disclosures required by generally accepted
         accounting principles.

3.  MAJOR CUSTOMER INFORMATION

         Historically, a significant portion of the Company's net revenues is
         derived from a limited number of customers. Approximately 28% of the
         Company's net revenues for the three months ended June 30, 1997 were
         from three customers accounting for 11%, 10%, and 7%, respectively, of
         net revenues. Approximately 27% of the Company's net revenues for the
         three months ended June 30, 1996 were from three customers accounting
         for 10%, 9%, and 8%, respectively, of net revenues.

4.  RECENT PRONOUNCEMENT

         In February 1997, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 128 ("SFAS No. 128"),
         "Earnings per Share." SFAS No. 128 establishes a different method of
         computing net income per share than is currently required under the
         provisions of Accounting Principles Board Opinion No. 15, "Earnings per
         Share." Under SFAS No. 128, the Company will be required to present
         both basic net income per share and diluted net income per share. Basic
         net income (loss) per share for the three months ended June 30, 1997
         would have been $(.10) per share as compared with $.12 per share for
         the corresponding periods in fiscal 1997. The impact of SFAS No. 128 on
         the calculation of diluted net income per share is not expected to be
         materially different from primary earnings per share. The Company plans
         to adopt SFAS No. 128 in its third quarter for fiscal 1998 and at that
         time all historical net income per share data presented will be
         restated to conform to the provisions of SFAS No. 128.

5.  CONTINGENCIES

         On August 2, 1995, Claircom Communications Group, Inc. ("Claircom")
         brought an action against the Company in King County (Washington)
         Superior Court alleging breach of contract, breach of warranty, and
         various related claims and seeking an accounting and damages arising
         from the joint development of a cabin telecommunications unit (CTU),
         which is part of a cabin communications system, to be installed in
         commercial passenger aircraft for providing communications services
         between the aircraft and the ground. On October 11, 1995, the Company
         filed an answer in the Washington action denying Claircom's allegations
         and asserted a Counterclaim. The Company also brought an action against
         Claircom, in the Hillsborough County (New Hampshire) Superior Court on
         September 12, 1995, seeking payment of royalties, protection of its
         trade secrets and damages for breach of contract under certain New
         Hampshire statutes. Claircom filed a Motion to Dismiss or Stay the New
         Hampshire action. On October 12, 1995, the New Hampshire court denied
         the Company's motion for preliminary injunction and Claircom's motion
         to dismiss or stay. On October 30, 1995, the Washington court granted
         the Company's motion to stay the Washington action. Claircom's motions
         to reconsider the orders of the New Hampshire and the Washington courts
         have both been denied. On May 9, 1997, the Court allowed Claircom's
         motion to amend its counterclaims to add claims for fraudulent
         inducement, intentional misrepresentation and a claim under the New
         Hampshire Consumer Protection Act. The Company has moved to dismiss
         these new counterclaims. Claircom has moved to dismiss, or for partial
         summary judgment on, the Company's claim under the New Hampshire
         Consumer Protection Act. The Court will hear argument on both motions
         at the status conference scheduled for August 27, 1997. Discovery is
         ongoing and the Court has set a trial date of May 1998.

         On June 20, 1997 the Company commenced an action in the United States
         District Court for the District of Delaware against AT&T Wireless
         Services, Inc. and Claircom, Civil No. 97-335. That action asserts that
         the defendants have infringed, and will continue to infringe, US Patent
         Number 5,553,135 (the " '135 patent") owned by the Company.
         Specifically the action contends that the defendants have violated the
         '135 patent by making, using, selling or offering to sell cabin
         telecommunications units employing the technology claimed and disclosed
         in the '135 patent. The suit is in its early stages, and the Company is
         unable to express a view as to its outcome.

                  Financial Condition and Results of Operations
                                  June 30, 1997


The statements contained in this Quarterly Report on Form 10-Q which are not
purely historical are forward-looking statements within the meaning of Section
27a of the Securities Act of 1933 and section 21E of the Securities Exchange Act
of 1934, including statements regarding the Company's expectations, hopes,
intentions or strategies regarding the future. Without limiting the foregoing,
the words "believes," "anticipates," "plans," "expects," and similar expressions
are intended to identify forward-looking statements. All forward-looking
statements included in this document are based on information available to the
Company on the date hereof, and the Company assumes no obligation to update any
such forward-looking statements. It is important to note there are a number of
important factors that could cause the Company's actual results to differ
materially from those indicated in any such forward-looking statements. These
factors include, without limitation, those set forth under the caption below
"Factors That May Affect Future Operating Results.

RESULTS OF OPERATIONS

Net revenues decreased by $1.9 million (17%) to $9.3 million for the three
months ended June 30, 1997 compared to $11.2 million for the three months ended
June 30, 1996. This decrease in revenue resulted primarily from a general
decrease in unit shipments to our IXC customers. Shipments to the Company's
application developers and reseller customers approximated 65% of revenues for
the three months ended June 30, 1997 compared to 44% for the three months ended
June 30, 1996. Included in these categories is a growing number of emerging
companies. Shipments to international customers represented approximately 53% of
total revenues for the quarter ended June 30, 1997 versus 41% for the same
quarter in 1996. The Company believes that its net revenues may level off or
even decline in certain periods preceding the introduction of an enhanced
version of its VCO 20 switch targeted for the fourth quarter of fiscal 1998 and
a new line of standards-based programmable switches targeted for fiscal 1999.

Gross profit decreased by $2.1 million (30%) to $4.9 million for the three
months ended June 30, 1997 compared to $7.1 million for the three months ended
June 30, 1996. Gross margin decreased to 53% in the three months ended June 30,
1997 from 63% in the three months ended June 30, 1996. The decrease in gross
margin resulted primarily from an increase in sales through the more highly
discounted indirect revenue channels, an increase in service revenue which
generates lower gross margins, a shift in product mix towards lower margin
systems and a series of charges related to consulting and other manufacturing
items. The Company does not believe that the current rates of gross margins are
necessarily indicative of future gross margins which may be affected by the
level of net revenues, customer mix, cost of components, and discounts granted
to high volume purchasers. As stated above, the Company's gross margins have
been declining and may continue to decline as a result of continued competitive
pricing pressure and increased use of indirect channels of distribution.

Selling, general and administrative expenses increased by $.1 million (4%) to
$3.5 million, or 38% of net revenues, for the three months ended June 30, 1997
compared with $3.4 million, or 30% of net revenues, for the three months ended
June 30, 1996. This increase in expenses was primarily attributable to expansion
of the Company's sales and support functions in combination with increased
professional services costs.

                                                                       PART I
                                                                       ITEM 2

Research and development expenses were $2.8 million or 30% of net revenues for
the three months ended June 30, 1997 compared to $2.8 million or 25% of net
revenues for the three months ended June 30, 1996. The Company's spending for
research and development is primarily directed towards the enhancement of it's
VCO-20 switch, its new project with Dialogic Corporation and Junction Inc., and
the provision of additional product functionality as it relates to
integrated SS-7, network management, scalability, certifications, subrate
switching and the development of future products. The Company believes that its
current spending level on research and development is required to advance its
position as a core network supplier for telecommunications service providers.

Operating income decreased by $2.3 million to a loss of $1.4 million for the
three months ended June 30, 1997 compared to a profit of $.9 million for the
three months ended June 30, 1996. The decrease was due primarily to the revenue
shortfall and lower gross margins.

The $.3 million increase in interest income for the three month period ended
June 1997, when compared to the same period for the previous fiscal year, was
principally the result of a one time gain on the sale of an available-for-sale
security and increased interest income from investments.

At June 30, 1997, the Company had $30.4 million in cash and cash equivalents and
current and non-current investments. At March 31, 1997, the Company had $32.3
million in cash and cash equivalents and current and non-current investments.
During the three months ended June 30, 1997, cash and cash equivalents decreased
$4.9 million. Of this decrease, $3 million resulted from a transfer of cash to
investment holdings. The balance of the reduction in cash during the three month
period was a result of increased purchases of property, equipment, and
inventory, a reduction in accounts payables and decreased cash inflow due to
lower sales levels. At June 30, 1997, the ratio of current assets to current
liabilities was 3.8:1 compared to 3.3:1 at March 31, 1997. Purchase commitments
to suppliers of the Company's products were approximately $7.1 million and $9.7
million at June 30, 1997 and March 31, 1997, respectively.

The Company maintains an unsecured bank line of credit in the amount of $6.0
million. At June 30, 1997, no borrowings were outstanding under this line.
Unless renewed, the line expires in September 1997. This line bears interest at
the bank's prime interest rate per annum (8.5% at June 30, 1997). The Company
believes that cash generated from operations and the total of its cash and
current investments, together with existing sources of debt financing, will be
sufficient to meet its anticipated cash requirements for working capital and
capital expenditures for at least the next twelve months. The Company does not
currently anticipate that it will be required to sell a substantial percentage
of its non-current investments in the near term.

On December 16, 1996, the Company's Board of Directors authorized the repurchase
of up to 500,000 shares of common stock as an extension of the Company's
repurchase program. Such repurchases will be funded through the Company's cash
and investments. As of June 30, 1997, the Company had repurchased a cumulative
total of 393,500 shares related to this extension at an average cost of $10.25
per share and had reissued 12,035 shares at an average price of $9.56 related to
purchases under its Employee Stock Purchase Plan. The Company may repurchase
additional shares of its stock depending on stock market conditions, price per
share and other factors.

The Company does not consider the impact of inflation on its business activities
to have been significant to date.

                                                                       PAGE 8

FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS

A number of uncertainties exist that could affect the Company's future operating
results, including without limitation, the following:

     -    The Company has recently announced agreements in principle with
          Dialogic Corporation and Junction, Inc. which it anticipates will
          result in the creation of future products. The Company anticipates
          that the expenses associated with this developmental activity will be
          partially funded from its fiscal 1998 budget; the balance will be
          charged to operating expenses. There can be no assurance that this
          relationship will result in the development of salable product(s)
          which will be beneficial to the future of the Company or that products
          produced by this relationship will be developed in a cost-effective
          manner and be available for sale within the time frame required.

     -    The Company is dependent upon sole source suppliers for certain key
          components used in its products. The Company purchases these sole
          source components pursuant to purchase orders placed from
          time-to-time. No assurance can be given that sole source suppliers
          will devote the resources necessary to support the enhancement or
          continued availability of such components or that any such supplier
          will not encounter financial or operational difficulties. In addition,
          in certain instances, components required for certain subassemblies
          used in the Company's products are no longer being manufactured. The
          Company has historically been able to secure such components by
          utilizing its network of suppliers. However, the Company is
          redesigning such sub-assemblies in order to eliminate production
          interruptions that could occur if such components cannot be acquired.
          The Company is actively seeking alternative solutions to address
          potentially serious delays or shortages from its major component
          supplier. If delays or shortages occur and the Company is unable to
          effect alternative supply arrangements, its business and results of
          operations could be materially adversely affected.

     -    A variety of factors could influence the level of the Company's net
          revenues in a particular quarter, including general economic
          conditions in the telecommunications switching industry, the timing of
          significant orders, shipment delays, the introduction of new products
          by the Company, the introduction of new products by the Company's
          competitors, acquisitions by the Company, patterns of capital spending
          by customers and other factors, many of which are beyond the Company's
          control. Since a substantial portion of the expenses of the Company do
          not vary relative to sales levels, if net revenues in particular
          quarter do not meet expectations, it could have a material adverse
          effect on the Company's results of operations.

     -    The Company's gross margin has declined in recent periods and may
          continue to decline as a result of potential sales price reductions
          and increased use of indirect distribution channels. Gross margins are
          also affected by other factors such as changes in the cost of
          materials, production and quality considerations, and the timing of
          new product introductions. The Company from time-to-time adds
          functionality and features that add cost to its products, and the
          Company's gross margins will be adversely affected to the extent the
          Company is not able to increase the price of such systems to offset
          such increased costs.

                                                                       PAGE 9


     -    The Company's future results of operation and financial condition will
          depend, in part, on its ability to obtain and maintain patent
          protection for its products, to preserve its trade secrets and to
          operate without infringing on proprietary rights of third parties.
          There can be no assurance that the Company will be able to obtain
          and/or adequately protect the intellectual property required for it to
          compete effectively.

     -    The Company's ability to develop marketable products and maintain a
          competitive position in light of continuing technological developments
          will depend, in large part, on its ability to attract and retain
          highly qualified management, technical and sales and marketing
          personnel. Competition for the services of these key employees is
          intense.

     -    The Company's international business is subject to a number of
          inherent risks, including the challenges of building and managing
          foreign operations, unique product requirements, fluctuations in the
          value of foreign currencies, import/export duties, and unexpected
          regulatory, economic or political changes in foreign markets.

     Because of these and other factors, past financial performance should not 
be considered an indictor of future performance.

ITEM 1 - LEGAL PROCEEDINGS

         On August 2, 1995, Claircom Communications Group, Inc. ("Claircom")
         brought an action against the Company in King County (Washington)
         Superior Court alleging breach of contract, breach of warranty, and
         various related claims and seeking an accounting and damages arising
         from the joint development of a cabin telecommunications unit (CTU),
         which is part of a cabin communications system, to be installed in
         commercial passenger aircraft for providing communications services
         between the aircraft and the ground. On October 11, 1995, the Company
         filed an answer in the Washington action denying Claircom's allegations
         and asserted a Counterclaim. The Company also brought an action against
         Claircom, in the Hillsborough County (New Hampshire) Superior Court on
         September 12, 1995, seeking payment of royalties, protection of its
         trade secrets and damages for breach of contract under certain New
         Hampshire statutes. Claircom filed a Motion to Dismiss or Stay the New
         Hampshire action. On October 12, 1995, the New Hampshire court denied
         the Company's motion for preliminary injunction and Claircom's motion
         to dismiss or stay. On October 30, 1995, the Washington court granted
         the Company's motion to stay the Washington action. Claircom's motions
         to reconsider the orders of the New Hampshire and the Washington courts
         have both been denied. On May 9, 1997, the Court allowed Claircom's
         motion to amend its counterclaims to add claims for fraudulent
         inducement, intentional misrepresentation and a claim under the New
         Hampshire Consumer Protection Act. The Company has moved to dismiss
         these new counterclaims. Claircom has moved to dismiss, or for partial
         summary judgment on, the Company's claim under the New Hampshire
         Consumer Protection Act. The Court will hear argument on both motions
         at the status conference scheduled for August 27, 1997. Discovery is
         ongoing and the Court has set a trial date of May 1998.

         On June 20, 1997 the Company commenced an action in the United States
         District Court for the District of Delaware against AT&T Wireless
         Services, Inc. and Claircom, Civil No. 97-335. That action asserts that
         the defendants have infringed, and will continue to infringe, US Patent
         Number 5,553,135 (the " '135 patent") owned by the Company.
         Specifically the action contends that the defendants have violated the
         '135 patent by making, using, selling or offering to sell cabin
         telecommunications units employing the technology claimed and disclosed
         in the '135 patent. The suit is in its early stages, and the Company is
         unable to express a view as to its outcome.

[SUMMA FOUR LOGO]                                                 EXHIBIT 10.36


                              EMPLOYMENT AGREEMENT
                              --------------------

         THIS EMPLOYMENT AGREEMENT (the "Agreement"), made this 15th day of

its principal place of business at Manchester, New Hampshire (the "Company"),
and Richard Swee (the "Employee").

         The Company desires to employ the Employee, and the Employee desires to

reasonable travel, entertainment and other expenses incurred, per the Company's
Travel and Entertainment Policy, or paid by the Employee in connection with, or
related to, the performance of his duties, responsibilities or services under
this Agreement, as more fully described in section 12.5.3, upon presentation by
the Employee of documentation, expense statements, vouchers and/or such other
supporting information as the Company may request, PROVIDED, HOWEVER, that (i)
the amount available for such travel, entertainment and other expenses may be
fixed in advance by senior management or the Board and (ii) amounts so
reimbursed for gasoline will be included in Employee's taxable income except as
so documented as a business expense.

               3.5   STOCK OPTION. Subject to Board approval, the Employee
shall be granted an incentive stock option to purchase 30,000 shares of the
Company's common stock under its 1993 Stock Incentive Plan (the "Plan"). The
option price shall be the closing price on the first day of the month following
the employment start date month. The option to purchase 30,000 shares shall vest
over four years at 25% per year. If, in the future, the Board votes to shorten
the vesting schedule for Officers generally, then any of the Employee's unvested
shares would fall under the new, more favorable vesting schedule. Stock options
granted may be exercised by the Employee, to the extent vested in accordance
with the terms of the Plan. If, after completing six months of service,
Employee's employment is involuntarily terminated by the Company for any reason
other than "Cause", any unvested shares, which would have otherwise vested
within 12 months of such involuntary termination, shall vest immediately.

         4.    EMPLOYMENT TERMINATION WITHOUT CAUSE.  The Employee shall have 
the status of an employee at will. The Company may terminate the Employee's
employment at any time without cause. The Employee has no obligation to remain
employed by the Company and may terminate his employment at any time.

               4.1   TERMINATION FOR CAUSE. In the event the Employee's
employment is terminated for cause the Company shall pay to the Employee the
compensation and benefits otherwise payable to him under Section 3 through the
last day of his actual employment by the Company. For purposes of this
Agreement, "cause" for termination shall be deemed to exist upon (a) alcohol or
drug abuse affecting the performance of your duties, theft, embezzlement, fraud,
absenteeism, dishonesty, gross negligence or misconduct, or (b) the conviction
of the Employee of, or the entry of a pleading of guilty or nolo contendere by
the Employee to, any crime involving moral turpitude or any felony.

               4.2   TERMINATION FOR DEATH OR DISABILITY. If the Employee's
employment is terminated by death or because of disability, the Company shall
pay to the estate of the Employee or to the Employee, as the case may be, the
compensation which would otherwise be payable to the Employee up to the end of
the month in which the termination of his employment because of death or
disability occurs, as well as any benefits due Employee under the benefits
programs, e.g., life insurance. For purposes of this Agreement, the term
"disability" shall mean the inability of the Employee, due to a physical or
mental disability, for a period of 90 days, whether or not consecutive, during
any 360-day period to perform the services contemplated under this Agreement. A
determination of disability shall be made by a physician satisfactory to both
the Employee and the Company, PROVIDED THAT if the Employee and the Company do
not agree on a physician, the Employee and the Company shall each select a
physician and these two together shall select a third physician, whose
determination as to disability shall be binding on all parties.

               4.3   TERMINATION BY THE COMPANY OTHER THAN FOR CAUSE. If the
Employee's employment is terminated by the Company for any reason other than for
cause, the Company shall continue paying the Employee's current base salary and
insurance benefits, after the Employee's termination of employment, for up to
twelve (12) months (the "Severance Benefit"). Payment of


                                      -4-
<PAGE>   5
the Severance Benefit shall cease upon the earlier of (a) the first anniversary
of the Employee's date of termination, or (b) the date the Employee begins
employment with another employer (or is re-employed by the Company).

               4.4   TERMINATION FOLLOWING CHANGE IN CONTROL. If the Employee's
employment is terminated by the Company for any reason other than cause within
one year after a change in control, or the Employee experiences a substantial
diminution in the nature or status of his responsibilities from those set forth
in his job description, and the Employee chooses to terminate employment, the
Company shall continue paying the Employee's current base salary and benefits,
after the Employee's termination of employment, for up to twelve (12) months
(the "Severance Benefit"). Payment of the Severance Benefit shall cease upon the
earlier of (a) the first anniversary of the Employee's date of termination, or
(b) the date the Employee begins employment with another employer (or is
re-employed by the Company). In the event of change of control, the Employee's
unvested shares shall vest immediately, in accordance with section 16 of the
Company's 1995 stock plan. For the purposes of this paragraph, a change in
control is defined as provided for in Attachment "A".

         5.    NON-COMPETE.

               (a)   During the Employment Period and for a period of twelve
(12) months after the Employee's termination of employment for any reason, the
Employee will not knowingly directly or indirectly:

               (i)   as an individual proprietor, partner, stockholder, officer,
employee, director, joint venturer, investor, lender, consultant or in any other
capacity whatsoever (other than as the holder of not more than one percent (1%)
of the total outstanding stock of a publicly held company), render any services
to any business engaged in the design, manufacture or sale of programmable
switches (including, without limitation, Excel) or to any non-legacy switch


                                      -5-

manufacturer (including, without limitation, Sattel) or any major original
equipment manufacturer customer of Excel (including, without limitation, Boston
Technology, Glenayre or Access Line); or

               (ii)  recruit, solicit or induce, or attempt to induce, any
employee or employees of the Company to terminate their employment with, or
otherwise cease their relationship with, the Company; or

               (iii) solicit, divert or take away, or attempt to divert or to
take away, the business or patronage of any of the clients, customers or
accounts, or prospective clients, customers or accounts, of the Company which
were contacted, solicited or served by the Employee while employed by the
Company.

               (b)   If any restriction set forth in this Section 5 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 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.

               (c)   The restrictions contained in this Section 5 are necessary
for the protection of the business and goodwill of the Company and are
considered by the Employee reasonable for such purpose. The Employee agrees that
any breach of this Section 5 will cause the Company substantial and irrevocable
damage and therefore, in the event of any such breach, in addition to such other
remedies which may be available, the Company shall have the right to seek
specific performance and injunctive relief.

         6.    NOTICES. All notices required or permitted under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the United States Post Office, by registered or certified mail,
postage prepaid, addressed to the other party at the address

this Agreement shall include the corresponding masculine, feminine or neuter
forms, and the singular forms of nouns and pronouns shall include the plural,

agreement between the parties and supersedes all prior agreements and
understandings, whether written or oral, relating to the subject matter of this
Agreement.

         9.    AMENDMENT.  This Agreement may be amended or modified only by a 
written instrument executed by both the Company and the Employee.

        10.    GOVERNING LAW.  This Agreement shall be construed, interpreted
and enforced in accordance with the laws of the State of New Hampshire.

        11.    SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of both parties and their respective successors and
assigns, including any corporation with which or into which the Company may be
merged or which may succeed to its assets or business, provided, however, that
the obligations of the Employee are personal and shall not be assigned by him.

        12.    MISCELLANEOUS.

               12.1  No delay or omission by the Company in exercising any
right under this Agreement shall operate as a waiver of that or any right. A
waiver or consent given by the Company on any one occasion shall be effective
only in that instance and shall not be construed as a bar or waiver of any right
on any other occasion.

<PAGE>   4
     2.5  JOINT APPROVAL OF BUSINESS PLAN. Joint Approval of the Business Plan
          shall occur only when the Business Plan has been initialed and dated
          by the senior executive officer of each of Summa Four and Junction.

     2.6  JOINT VENTURE AGREEMENT. As promptly as possible following Joint
          Approval of the Business Plan, the parties shall execute the Joint
          Venture Agreement in a form which is reasonably acceptable to them.
          The Joint Venture Agreement shall contain, at a minimum, the
          provisions attached hereto as SCHEDULE B, and will also incorporate
          the schedules, milestones and obligations pertaining to the Project
          which are set forth in the Business Plan.

3    EXCLUSIVITY. Junction agrees that during Phase I and, as described in
     Section 6.2(c) below, for certain periods following the termination of
     Phase I, Junction shall not, and shall require each of its shareholders,
     employees and consultants not to, engage, directly or indirectly, in any
     activity which is or would be competitive with the Product or any variation
     or derivative thereof. Junction agrees and acknowledges that the payments
     to be made by Summa Four to Junction hereunder are sufficient to compensate
     Junction and its shareholders, employees and consultants for the
     non-competition obligation set forth in this Section 3, and that the level
     of such payments has been set specifically contemplating this
     non-competition obligation. Junction agrees that it shall require its
     shareholders, employees and consultants to enter into binding, written
     agreements (enforceable by Summa Four) requiring them to comply with the
     terms of this Section 3, and Junction shall pay each such person such
     amounts as are necessary to compensate them for such non-competition
     obligation (it being understood that such amounts will be subject to
     reimbursement by Summa Four as Personnel/Salary expense, subject to the
     provisions and limitations of Section 4 and the caps set forth in Schedule
     D).

4    FUNDING. Summa Four will pay or reimburse Junction's documented expenses
     incurred in connection with development of the Business Plan during the
     first 120 days of Phase I (or until earlier termination of Phase I pursuant
     to Section 6.1), up to the amounts set forth on SCHEDULE D hereto. Summa
     Four will reimburse Junction no later than thirty (30) days following the
     end of each calendar quarter for such expenses incurred by Junction during
     the preceding quarter as to which Junction has submitted an invoice
     requesting reimbursement prior to the end of the quarter. At Junction's
     option, Summa Four may pay Junction's suppliers directly, on terms and
     conditions acceptable to Summa Four and such suppliers. Summa Four will not
     be responsible for paying any amounts under this Section 4 in excess of
     those shown on SCHEDULE D; provided, however, that if circumstances beyond
     Junction's reasonable control result in increased costs to Junction, Summa
     Four will in good faith discuss increasing the amount of funding with
     Junction.

5    INTELLECTUAL PROPERTY.

     5.1  OWNERSHIP. Summa Four shall own all right, title and interest in and
          to the Business Plan, and all ideas, inventions, designs, algorithms
          and methods described therein or formulated during the development
          thereof, and all patent, copyright, trademark, trade secret, mask work
          and other industrial and intellectual property rights therein
          throughout the world, together with all applications, registrations
          and renewals thereof (collectively, the "Proprietary Rights").
          Junction hereby irrevocably sells and assigns all its right, title and
          interest in and to the Proprietary Rights throughout the world,
          whether existing now or developed in the future, to Summa Four.
          Junction shall ensure that any subcontractor it engages to assist in
          the development of the Business Plan or Product also assigns all
          Proprietary Rights to Summa Four. At the request of Summa Four,
          Junction and any such subcontractor shall execute and deliver all
          assignments, instruments, affidavits, powers of attorney and other
          documents as are necessary to effect the foregoing assignment. Summa
          Four shall have the exclusive right to file patent and copyright
          applications to protect the Proprietary Rights, and to assert the
          Proprietary Rights against third parties.

     5.2  LICENSED SUMMA FOUR TECHNOLOGY.

          (a)  Summa Four hereby grants to Junction, and Junction accepts, a
               non-exclusive, non-transferable license during Phase I to
               reproduce, use and create derivative works of that Summa Four
               technology described in SCHEDULE C and related documentation (the
               "Licensed Summa Four Technology"), solely at Junction's facility
               in California and Summa Four's facilities, for the sole purposes
               of preparing the Business Plan as described in this Agreement.
               Junction shall have no right to sublicense any rights in the
               Licensed Summa Four Technology without the express prior written
               consent of Summa Four.

          (b)  Summa Four shall provide the Licensed Summa Four Technology to
               Junction in a format which the parties reasonably agree is
               necessary for Junction to perform its obligations hereunder.
               Junction shall notify Summa Four immediately in the event of any
               actual or suspected unauthorized access to, use of or tampering
               with the Licensed Summa Four Technology. Junction agrees that the
               Licensed Summa Four Technology shall constitute Confidential
               Information of Summa Four, as defined in the Confidentiality
               Agreement (as defined in Section 8 below).

          any patent, copyright, trademark, trade secret, mask work or other
          intellectual or industrial property right of any third party.

     (b)  Summa Four shall notify Junction promptly in writing of any third
          party action (and provide information regarding all prior related
          claims) brought against Summa Four based on a claim described in
          Section 5.3(a) above and not otherwise described in Section 5.3(d)
          below. Junction shall defend such action at its expense and pay all
          Damages attributable to such claim incurred by Summa Four (as they are
          incurred). Junction shall have sole control of the defense of any such
          action and all negotiations for its settlement or compromise. Summa
          Four shall reasonably cooperate with Junction in the defense of such
          claim, and may be represented at Summa Four's expense, by counsel of
          Summa Four's selection.

     (c)  In the event that a permanent injunction based solely on a claim
          indemnified by Junction under Section 5.3(a) is obtained against the
          parties' use or development of the Business Plan or their development,
          use or distribution of the Product, then Summa Four shall have the
          right to terminate this Agreement in accordance with Section 6.

     (d)  The provisions of Section 5.3(a) notwithstanding, Junction shall not
          have any liability to Summa Four (including any obligation to
          indemnify, defend or hold harmless) to the extent that any claim of
          infringement or violation is based upon the Licensed Summa Four
          Technology.

     (e)  Notwithstanding anything to the contrary contained above, in the event
          that this Agreement is terminated by Summa Four pursuant to Sections
          6.1(b) or 6.1(c), Junction shall not be required to indemnify Summa
          Four with respect to Damages which are, in the aggregate, in excess of
          the aggregate amounts paid by Summa Four to Junction under this
          Agreement

     5.4  INDEMNIFICATION BY SUMMA FOUR.

          (a)  Summa Four shall indemnify, defend and hold Junction harmless
               from and against any Damages arising from any claim that the
               Licensed Summa Four Technology infringes or violates any patent,
               copyright, trademark, trade secret, mask work or other
               intellectual or industrial property right of any third party.

          (b)  Junction shall notify Summa Four promptly in writing of any third
               party action (and provide information regarding all prior related
               claims) brought against Junction based on a claim described in
               Section 5.4(a) above. Summa Four shall defend such action at its
               expense and pay all Damages attributable to such claim incurred
               by Junction (as they are incurred). Summa Four shall have sole
               control of the defense of any such action and all negotiations
               for its settlement or compromise. Junction shall reasonably
               cooperate with Summa Four in the defense of such claim, and may
               be represented, at Junction's expense, by counsel of Junction's
               selection.

          (c)  The provisions of Section 5.4(a) notwithstanding, Summa Four
               shall not have any liability to Junction to the extent that any
               claim of infringement is based upon use of the Licensed Summa
               Four Technology for any purpose unrelated to the development of
               the Business Plan or the Product as described in this Agreement.


          (d)  Notwithstanding anything to the contrary contained above, in the
               event that this Agreement is terminated by Summa Four pursuant to
               Sections 6.1(b) or 6.1(c), Summa Four shall not be required to
               indemnify Junction with respect to Damages which are, in the
               aggregate, in excess of the aggregate amounts paid by Summa Four
               to Junction under this Agreement.

               embodying, describing or including the Business Plan, the
               Licensed Summa Four Technology or the Product.

     6.3  TERMINATION ROYALTY. For purposes of this Agreement, "Termination
          Royalty" shall mean ***** of Summa Four's revenue from the Product,
          including any variation or derivative of such Product. The Termination
          Royalty shall be payable quarterly, and shall be paid, if any is due,

          the parties mutually agree in writing that it shall be terminated, or
          until all obligations required to be discharged hereunder have been

          termination of this Agreement.

7    VALUATION.

     7.1  Promptly following the commencement of Phase II, the business Plan
          will be provided to Wessels, Arnold & Henderson, Montgomery Securities
          or other investment banking firm of national standing (as may be
          agreed upon by the parties) to determine a formula for the value,
          during the Exit Period defined below, of the Product to Summa Four
          (assuming that Summa Four had a paid-up, royalty-free, exclusive
          license to the Product and variations and derivatives thereof) for
          purposes of the put and call arrangements described in SCHEDULE B. The
          valuation formula will include such factors as revenues from the
          Product, impact of the Product on Summa Four's stock price, Junction's
          success during Phase II in meeting time and Product performance
          milestones, dilution effect (if any) on the valuation of Summa Four
          stock (in the event Summa Four uses its stock to exercise any portion
          of its call option under the Joint Venture Agreement) and such other
          factors as Summa Four and Junction may agree upon or as the investment
          banker may deem relevant. The investment banker will also recommend

          of the commencement of Phase II for the purposes described in Section
          7.2, which shall be not less than ***** and not greater than ***** and
          which shall be based upon the relative value of (i) Summa Four's
          funding of Phase I and Summa Four's contributions to be made during
          Phase II pursuant to the Business Plan in relation to (ii) the value
          of the contributions, financial or otherwise, made by Junction during

          Phase I are in excess of the amount of the "Personnel" expenses
          reimbursed by Summa Four pursuant to Section 4 of this Agreement and
          SCHEDULE D), and the contributions, financial or otherwise, to be made
          by Junction during Phase II pursuant to the Business Plan. The fees of
          the investment banker for such services shall be paid by the Joint
          Venture.

     7.2  Upon receipt of the investment banker's report pursuant to Section 7.1

                                   SCHEDULE B


PROVISIONS TO BE INCLUDED IN JOINT VENTURE AGREEMENT

1    At the commencement of Phase II, Summa Four and Junction will each
     contribute all rights and interest they may have in the Product to the
     Joint Venture. The interests of Summa Four and Junction in the Joint
     Venture shall initially be **% for Summa Four, and **% for Junction,
     subject to adjustment as described in Paragraph 6 below.

2    Summa Four will engage the Joint Venture to develop and test the Product
     according to the Business Plan, pursuant to a Development Agreement which
     is mutually acceptable to Summa Four and Junction, and which will include
     customary arm's-length warranties and indemnities for a software
     development contract. Summa Four will make cash payments to the Joint
     Venture sufficient to fund those expenses called for in the Business Plan.
     Summa Four will also procure and contribute or lease to the Joint Venture
     equipment and software required to conduct development of the Product and
     any variation or derivative thereof. Summa Four will license any necessary
     Licensed Summa Four Technology to the Joint Venture for purposes of its
     development of the Product. In the event that the expenses of the Joint
     Venture exceed those estimated in the Business Plan, the parties will
     explore in good faith means of funding the ongoing operations of the Joint
     Venture, including but not limited to additional capital contributions by
     the parties and outside sources of funding.

3    The Joint Venture will subcontract the development of the Product to
     Junction, which will be responsible for providing a sufficient number of
     qualified technical personnel (including engineering, design and
     programming personnel) to successfully complete the Project and procuring
     and providing sufficient office and laboratory space for the Project.

4    Upon the commencement of Phase II, the Joint Venture will grant Summa Four
     a five-year, paid-up, royalty-free, exclusive, worldwide license to use,
     manufacture, distribute and exercise all other rights with respect to the
     Product and all other technology developed or owned by the Joint Venture,
     under all intellectual property therein. Such license shall provide that at
     the expiration of such five-year period, Summa Four shall be entitled to
     extend the term of the license for such fees and/or royalties as Summa
     Four, Junction and the Joint Venture shall unanimously reasonably agree
     upon.

         Confidential materials omitted and filed separately with the
         Securities and Exchange Commission. Asterisks denote omissions.

5    The Joint Venture will be managed by a Board of Managers appointed by Summa
     Four and Junction. The Board of Managers will be comprised of the President
     of Junction, the President of Summa Four, and one additional member
     designated by Summa Four and such additional members as Junction and Summa
     may agree upon, provided that at all times a majority of the Board shall be
     designees of Summa Four. The Board will act by majority vote on all
     matters.


6    Between the second and fifth anniversaries of the commencement of Phase II
     (the "Exit Period"), a set of puts and calls will be exercisable to allow
     either Junction to sell all or any portion of its interest in the Joint
     Venture to Summa Four at a specified discount to the valuation at the time
     of exercise (which discount shall be determined by the financial advisor
     described in Section 7.1 by reference to the valuation formula provided for
