                              EXPLANATORY NOTE

   This Registration Statement on Form S-3, as amended (the "Registration
Statement"), including the Prospectus forming a part hereof, assumes
consummation of the acquisition (the "Acquisition") of certain assets and
stock of CyberGuard Corporation (formerly known as Harris Computer Systems
Corporation) by the Registrant.  No shares of Common Stock will be issued
or sold until after the Acquisition has been consummated.  Accordingly,
this Prospectus has been prepared as if the Acquisition has been consummat-
ed.  No shares of Common Stock will be sold if the Acquisition is not
consummated.


     PROSPECTUS (Subject to Completion)
     Issued June __, 1996

                              1,200,000 SHARES
                      CONCURRENT COMPUTER CORPORATION
                                COMMON STOCK

          This Prospectus relates to the offering by Concurrent
     Computer Corporation ("Concurrent") of up to 1,200,000  shares of
     common stock, par value $.01 per share (the "Common Stock") of
     Concurrent, including shares that may be sold by Concurrent at
     the direction of Berenson Minella & Company ("Berenson Minella"), 
     shares that may be sold by Concurrent at the direction of John T.
     Stihl, the Chairman of the Board of Directors of Concurrent and
     shares that may be sold by Concurrent on behalf of certain former
     executive officers of Concurrent, for their respective benefits. 
     See "Use of Proceeds,"  "Certain Arrangements with Berenson
     Minella" and "Plan of Distribution."  The Common Stock includes a
     right to purchase fractional shares of preferred stock of Concur-
     rent, as provided in Concurrent's Rights Agreement, dated as of
     July 31, 1992.

          The Common Stock is traded in the over-the-counter market
     and price quotations therefor are reported on the National
     Association of Securities Dealers Automated Quotation System
     ("NASDAQ") National Market System  ("Nasdaq/NMS") under the
     symbol "CCUR".  The last reported sale price of the Common Stock
     on June 5, 1996 was $2 9/16 per share.

          THE SECURITIES OFFERED HEREBY REPRESENT A SIGNIFICANT DEGREE
     OF RISK.  INVESTORS SHOULD CAREFULLY CONSIDER CERTAIN RISKS AND
     OTHER CONSIDERATIONS RELATING TO THE COMMON STOCK AND CONCURRENT.
     SEE "RISK FACTORS" BEGINNING ON PAGE 8.

     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
     COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY
     STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF
     THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

          Concurrent, directly, or through agents designated from time
     to time by it, Berenson Minella or Mr. Stihl or through dealers
     or underwriters also to be so designated, may sell the Common
     Stock from time to time on terms to be determined at the time of
     sale.  The distribution of the shares of Common Stock by Concur-
     rent is not subject to any underwriting agreement.  Concurrent
     may sell the shares of Common Stock covered by the Prospectus
     through the Nasdaq/NMS, at prices and terms then prevailing,
     through customary brokerage channels, in privately negotiated
     transactions or otherwise, either through broker-dealers acting
     as agents or brokers for the seller, or through broker-dealers
     acting as agents or principals.  Such broker-dealers may receive
     compensation in the form of underwriting discounts, concessions,
     or commissions from Concurrent and/or the purchasers of the
     shares of Common Stock for whom they may act as agent, which
     compensation may be in excess of customary commissions.  To the
     extent required, the purchase price,  the names of any such
     agent, dealer or underwriter, and any applicable commission or
     discount with respect to a particular offering will be set forth
     in an accompanying Prospectus Supplement.  The aggregate net
     proceeds from the sale of any shares of the Common Stock will be
     the price thereof less the aggregate agent's commission or
     underwriter's discount, if any.  See "Plan of Distribution" for
     information regarding the designation of certain selling agents
     and indemnification arrangements.

          No person has been authorized in connection with any offer-
     ing made hereby to give any information or to make any represen-
     tations other than those contained in this Prospectus or any
     Prospectus Supplement, and, if given or made, such information or
     representations must not be relied upon as having been authorized
     by Concurrent or any underwriter, dealer or agent.  This Prospec-
     tus or any Prospectus Supplement does not constitute an offer to
     sell or the solicitation of an offer to buy any securities other
     than the securities to which it relates or any offer to sell or
     the solicitation of an offer to buy such securities in any
     circumstances in which such offer or solicitation is unlawful. 
     Neither the delivery of this Prospectus or any Prospectus Supple-
     ment nor any sale hereunder or thereunder shall, under any
     circumstances, create any implication that the information
     contained herein or therein is correct as of any time subsequent

                      CONCURRENT COMPUTER CORPORATION

     GENERAL

          Concurrent is a supplier of high-performance real-time
     computer systems.  "Real-time" systems acquire, analyze, store,
     display and control analog, digital and network data to provide
     time critical information as real-world events occur.  Concurrent
     has over 25 years of experience in real-time systems, including
     specific expertise in systems, applications software, productivi-
     ty tools and networking.  Concurrent's real-time systems offer
     networked and distributed computing solutions and may be config-
     ured to provide fault tolerance.  Concurrent sells its systems
     worldwide to end-users as well as to original equipment manufac-
     turers, systems integrators, independent software vendors and
     value-added resellers who combine Concurrent's products with
     other equipment or with additional application software for
     resale to end-users.  End uses of Concurrent's systems include
     product design and testing; flight simulation; air traffic
     control and weather forecasting; intelligence data acquisition
     and analysis; financial trading; and hospital information manage-
     ment.  Concurrent designs, manufactures, sells, and supports
     real-time proprietary and standards-based open systems.  It also
     offers traditional maintenance and support services and profes-
     sional services, such as performance and capacity analysis and
     systems integration.

     THE ACQUISITION

          On June __, 1996, Concurrent acquired (the "Acquisition")
     the assets of the real-time computer business of CyberGuard and
     683,178 newly issued shares of common stock of CyberGuard (the
     "CyberGuard Stock") pursuant to the Purchase and Sale Agreement
     dated as of March 26, 1996, as amended and restated on May 23,
     1996 (the "Purchase and Sale Agreement").  CyberGuard or its
     predecessors has been engaged in the real-time computing business
     since 1974.  The CyberGuard Stock represents approximately 9% of
     the common stock of CyberGuard outstanding immediately after the
     issuance of the CyberGuard Stock to Concurrent and after giving
     effect to the vesting and exercise of certain stock options. As
     consideration for the Acquisition, Concurrent issued to
     CyberGuard (i) 10,000,000 shares of Common Stock, which repre-
     sented approximately 23% of the shares of Common Stock outstand-
     ing immediately after such issuance, after giving effect to the
     vesting and exercise of all outstanding options with respect to
     the Common Stock, but without giving effect to the issuance of
     any shares of Common Stock offered hereby and (ii) 1,000,000
     shares of 9.00% Class B Convertible Preferred Stock (the "Con-
     vertible Preferred Stock") with $10,000,000 aggregate liquidation
     preference (subject to post-closing adjustments to reflect, among
     other things, the amount of net current assets transferred to
     Concurrent in the Acquisition) and convertible into a maximum of
     4,000,000 shares of Common Stock, subject to anti-dilution
     adjustments.  In addition, Concurrent also assumed certain
     liabilities of CyberGuard relating to its  real-time computing
     business.

          In connection with the Acquisition, Concurrent and
     CyberGuard entered into certain ancillary agreements including a
     Share Holding Agreement (the "Share Holding Agreement") that
     contains certain standstill, transfer and registration provisions
     relating to the Common Stock and the CyberGuard Stock, and
     provisions relating to the composition of the Board of Directors
     of Concurrent and CyberGuard.

          The Board of Directors of Concurrent believes the Acquisi-
     tion offers the following significant strategic and financial
     benefits to Concurrent and its stockholders, as well as to its
     employees and customers:

     *    Enhanced Competitive Position.      As a result of the
          Acquisition, Concurrent expects to be in a better position
          to meet the challenges of the increasingly competitive
          environment in the real-time computing industry more effec-
          tively than either Concurrent or CyberGuard standing alone. 
          In addition, Concurrent now has access to its own as well as
          CyberGuard's technology, allowing it to combine the best of
          both technologies in the next generation of products.

     *    Larger and More Diverse Market Coverage.  As a result of the
          Acquisition, Concurrent's service territory, installed base
          and product offerings are larger and more diverse than prior
          to the Acquisition.  In addition, the combination of the
          best of the technologies of the two companies is expected to
          allow for a reduction in the time between the introduction
          of next generation products within Concurrent's product
          line, resulting in Concurrent being less dependent on the
          success of any individual next generation product.

     *    Cost Savings.  The Acquisition is expected to generate
          significant cost savings during the first fiscal year. Such
          savings will be primarily obtained through headcount reduc-
          tions, as well as facilities cost reductions. These savings
          will be obtained through a variety of actions including,
          among others, integration of corporate management and admin-
          istrative functions, consolidation of production and re-
          search and development facilities and consolidation of
          sales/service offices.

     *    Liquidity.    The Acquisition has provided Concurrent with
          additional borrowing capacity under its revolving credit
          facility based on the higher borrowing base resulting from
          the combination of the real-time businesses of the two
          companies. Concurrent has entered into an amendment to the
          loan agreement with its primary lender which, among other
          things, extends the term of such agreement until August 1,
          1999 and effectively increases the line of credit under the
          revolving credit facility by $4.75 million to $12.75 mil-
          lion. In addition, the Acquisition has provided Concurrent
          with the opportunity to improve its liquidity by either
          selling or pledging, subject to certain restrictions, the
          shares of CyberGuard Stock owned by it.

          For a discussion of certain risks associated with the
     Acquisition, see "Risk Factors". CyberGuard is engaged in the
     development and marketing of commercial network security products
     designed to protect data on computer networks from access by
     unauthorized users.  For additional information concerning the
     Acquisition and the real-time business of CyberGuard, see the
     Joint Proxy Statement incorporated by reference herein.

          The following former executive officers of CyberGuard became
     executive officers of Concurrent upon consummation of the Acqui-
     sition:  Robert F. Chism (Vice President, Development), Daniel S.
     Dunleavy (Vice President and Chief Financial Officer), Robert T.
     Menzel (Vice President, North American Sales) and Michael N.
     Smith (Vice President, Marketing).  In addition, John T. Stihl
     and George E. Chapman remain executive officers and serve as
     Chairman of the Board and Vice President, International Sales,
     respectively, of Concurrent although Mr. Stihl resigned as
     President and Chief Executive Officer. The employment of six
     individuals as executive officers of Concurrent terminated upon
     consummation of the Acquisition.  Pursuant to their severance
     arrangements with Concurrent, which were amended, in part, in
     contemplation of the Acquisition, these former executive officers
     will receive severance compensation equal to their respective
     annual base salaries at the time of the Acquisition (an aggregate
     of $921,000) payable from the proceeds of the sale of a number of
     shares registered hereunder. Pursuant to the terms of the sever-
     ance arrangements, 40% of the severance obligation shall be paid
     to the former executive officers, not later than 30 days follow-
     ing consummation of the Acquisition with the remaining portion to
     be paid  not later than 60 days following consummation of the
     Acquisition (i.e., August 26, 1996).  See "Use of Proceeds."  For
     additional information with respect to the severance arrange-
     ments, see the Joint Proxy Statement incorporated by reference
     herein.

          The employment agreement with Mr. Stihl was also amended in
     contemplation of the Acquisition to provide him with the option
     to receive (i) full severance compensation (i.e., annual base
     salary) for the 24-month period commencing the day following the
     Closing Date or (ii) the proceeds from the sale, at Mr. Stihl's
     direction, of shares of Concurrent Common Stock with a fair
     market value of $730,000.  Mr. Stihl has elected to receive the
     proceeds from the sale of Common Stock and, accordingly, shares
     are registered hereunder for that purpose. 

          Berenson Minella was engaged as financial advisor to the
     Board of Directors of Concurrent in connection with the Acquisi-
     tion. For a description of the fee arrangement between Berenson
     Minella and Concurrent, see "Certain Arrangements with Berenson
     Minella".

     ADDITIONAL INFORMATION

          Concurrent's principal offices are located at Two Crescent
     Place, Oceanport, New Jersey 07757.  Its telephone number is
     (908) 870-4500. Concurrent's principal offices are being relocat-
     ed to 2101 West Cypress Creek Road, Fort Lauderdale, Florida
     33309.

          Concurrent has also filed with the Commission a registration
     statement on Form S-3 for 14,000,000 shares of Common Stock
     issued or issuable by Concurrent to CyberGuard (including a
     maximum of 4,000,000 shares of Common Stock, subject to anti-
     dilution adjustments, that are issuable upon conversion of the
     Convertible Preferred Stock or the debentures into which such
     Convertible Preferred Stock is exchangeable pursuant to its
     terms) in connection with the Acquisition.  Concurrent will not
     receive any of the proceeds from the sale of Common Stock offered
     by CyberGuard.

                              USE OF PROCEEDS

          Of the 1,200,000 shares of Common Stock being offered
     hereby, Concurrent will sell up to 412,000 shares as directed by
     Berenson Minella and will pay the net proceeds thereof to
     Berenson Minella without deducting the related estimated expenses
     (other than agent's commissions or underwriter's discounts, if
     any) in partial satisfaction of the advisory fee due from Concur-
     rent to Berenson Minella for its services as financial advisor to
     Concurrent in connection with the Acquisition.  Assuming a sale
     price of $__ per share (the last reported sale price of the
     Common Stock on June __, 1996), the net proceeds to Berenson
     Minella of the sale of all of such shares would be $_______.  See
     "Certain Arrangements with Berenson Minella" for a discussion of
     the rights of Berenson Minella with respect to such 412,000
     shares of Common Stock.  With respect to the severance owed to
     Mr. Stihl, based upon an assumed stock price of $______ per
     share, Concurrent expects to sell approximately 238,000 shares as
     directed by Mr. Stihl to satisfy such severance obligation.  If
     238,000 shares of Common Stock are insufficient to satisfy the
     severance obligation to Mr. Stihl, Concurrent will allocate such
     additional shares from the shares offered hereby as necessary to
     satisfy such obligation.  Of the remaining shares offered hereby,
     Concurrent intends to sell that number of shares sufficient to
     result in net proceeds of $921,000, after deducting the estimated
     expenses related to the sale of such shares, to satisfy the
     severance compensation obligations to certain former executive
     officers.  Any remaining shares after such sales will be
     deregistered and the Registration Statement will be terminated. 
     See "Plan of Distribution" for a discussion of the retention of
     specified agents to sell the shares of Common Stock offered hereby.

                                RISK FACTORS

          INVESTMENT IN THE COMMON STOCK OFFERED HEREBY INVOLVES A
     HIGH DEGREE OF RISK.  IN ADDITION TO THE OTHER INFORMATION
     CONTAINED IN THIS PROSPECTUS AND INCORPORATED BY REFERENCE
     HEREIN, PROSPECTIVE INVESTORS SHOULD CONSIDER CAREFULLY THE
     FOLLOWING FACTORS IN EVALUATING CONCURRENT BEFORE PURCHASING ANY
     SHARES OF COMMON STOCK.

     CHANGES IN MARKET PRICES OF COMMON STOCK; SHARES ELIGIBLE FOR FUTURE SALE

          General Market Risk

          Pursuant to the Purchase and Sale Agreement, Concurrent
     issued 10,000,000 shares of  Common Stock to CyberGuard, and
     CyberGuard issued  683,178 shares of CyberGuard Stock to Concur-
     rent.  The market prices of the Common Stock will vary from such
     price at the date of this Prospectus.  Such variation will be the
     result of changes in the business, operations or prospects of
     Concurrent, regulatory considerations, general market, economic
     and industry conditions, the results of operations, liquidity and
     the market's perception of the prospects of Concurrent as well as
     other factors affecting Concurrent including the risk factors set
     forth below.  Furthermore, because Concurrent owns 9% of the
     CyberGuard Stock, the price of the Common Stock will also reflect
     changes in the price of the CyberGuard Stock and in the business
     prospects for CyberGuard.  Despite Concurrent's ownership of the
     CyberGuard Stock and its right to designate one of CyberGuard's
     seven members of its Board of Directors, Concurrent will not be
     able to control CyberGuard's strategic direction or influence the
     day-to-day management of CyberGuard's business or the future
     results of CyberGuard's operations.

          Shares Eligible for Future Sale

          No assurance can be given as to the effect, if any, that
     future sales of shares of Common Stock, or the availability of
     shares of Common Stock for future sales, will have on the market
     price of the Common Stock from time to time.  Future sales of
     shares of Common Stock (including shares issued upon exercise of
     stock options), or the possibility that such sales could occur,
     could adversely affect the prevailing market price of the Common
     Stock.  As of the date of this Prospectus, the shares of Common
     Stock offered pursuant to this Prospectus, when aggregated with
     the shares of Common Stock that are issuable upon the exercise of
     the options, the shares of Common Stock being offered by
     CyberGuard (see "Concurrent Computer Corporation -- Additional
     Information") and the shares issuable upon the exercise of
     certain outstanding warrants to purchase 361,544 shares of Common
     Stock at $3 per share, equal approximately 40.9% of the shares of
     Common Stock outstanding.  As of the date of this Prospectus,
     there are 2,556,740 shares of Common Stock issuable upon exercise
     of options that are fully vested of which 2,366,822 options have
     an exercise price equal to or less than $3.00 per share.  An
     additional 6,056,209  shares of Common Stock or options therefor
     are reserved and available for future issuance under Concurrent's
     stock option plan.  The shares of Common Stock issued to
     CyberGuard are subject to the terms of the Share Holding Agree-
     ment between Concurrent and CyberGuard pursuant to which shares
     of Common Stock may be sold by CyberGuard subject to certain
     restrictions on transfer (including certain restrictions on the
     sales of shares when Concurrent is engaged in or preparing to
     engage in a public offering of Common Stock) and on the volume of
     sales by CyberGuard of Common Stock.  

     UNCERTAINTIES IN SUCCESSFULLY INTEGRATING THE CYBERGUARD REAL-
     TIME BUSINESS AND ACHIEVING COST SAVINGS

          Concurrent has begun cost savings actions relating to the
     Acquisition and expects full implementation thereof approximately
     six months after the Acquisition.  These savings will require
     significant reductions in employees, as well as consolidation of
     facilities worldwide and other miscellaneous cost savings ac-
     tions.  Obtaining these savings through the consolidation of
     functions, the integration of departments, systems and procedures
     and the relocation of staff present significant management
     challenges. The consolidation of development and manufacturing
     operations are especially challenging.  The failure to effective-
     ly consolidate development functions may result in delays in
     introduction of the next generation of products.  Similarly, the
     failure to effectively consolidate manufacturing operations could
     result in a delay in the shipment of certain customer orders and
     could affect the quality of the goods delivered.  Such failures
     could have a material adverse effect on the future financial
     performance, results of operations and financial condition of
     Concurrent.  There can be no assurance that such potential cost
     savings, operating efficiencies and other synergies will be
     successfully accomplished or accomplished within the time periods
     initially contemplated, particularly since liquidity issues (see
     " Potential Shortfall in Liquidity") may constrain Concurrent's
     ability to integrate the real-time businesses of Concurrent and
     CyberGuard.  Moreover, although the primary purpose of such
     actions is to realize direct cost savings and other operating
     efficiencies, there can be no assurance of the extent to which
     such cost savings and efficiencies can be achieved.

     IMPACT OF TRANSACTION COSTS ON FINANCIAL PERFORMANCE; UNCERTAINTY
     OF ACQUISITION-RELATED COSTS

          Concurrent expects to take a pre-tax charge in the range 
     of $29 to $32 million and to adjust goodwill to cover the
     transaction costs of the Acquisition and the costs of integrating
     the real-time businesses of Concurrent and CyberGuard, including
     the cost of facility closings and employee terminations to
     eliminate duplicate facilities and excess capacity and other non-
     recurring items.  Concurrent expects that such charges and
     related cash transaction costs will initially have a material
     adverse effect on Concurrent's financial performance and finan-
     cial condition within the period in which the charge and costs
     are taken.  Approximately $18 million of these costs are expected
     to be paid out in cash over the next two years (primarily fiscal
     year 1997), $9 to $11 million of the total charge are expected to
     be non-cash fixed asset carrying cost adjustments and approxi-
     mately $2 to $3 million are obligations which will be settled
     using proceeds of the offering of Common Stock made hereby.  Such
     costs include Acquisition expenses (such as investment banker,
     legal and accounting fees), employee, facility and equipment
     relocation costs and employee out-placement costs.  The $10
     million of remaining cash payments will be a continuation of
     current funding requirements and, after their full satisfaction,
     are expected to positively impact Concurrent's liquidity.  For
     example, cash expenditures for employee severance costs are
     expected to be paid out over time without increasing payroll
     costs; payroll costs are expected to decline as severance pay-
     ments cease.  There can be no assurances as to the actual amount
     of these charges or adjustments, and such charges or adjustments
     could be higher than current estimates.  In addition, there may
     be further charges in future periods relating to the cost of
     integrating the real-time business of Concurrent and CyberGuard. 
     However, the amount of such future charges cannot currently be
     determined.

     DECLINING TREND IN NET SALES

          Over the past five years, annual net sales of Concurrent
     generally have declined from a high of approximately $255 million
     to an annualized rate in the current fiscal year of approximately
     $100 million.  With the exception of the quarter ended June 30,
     1995, where net sales increased $162,000 over the prior quarter,
     net sales of Concurrent declined quarter to quarter during the
     fiscal year ended June 30, 1995 from $41.5 million in the first
     quarter to $30.5 million in the fourth quarter for total net
     sales during the period of $140.1 million.  The trend continued
     in the first two quarters of the fiscal year ended June 30, 1996. 
     Net sales for the three months ended September 30, 1995 were
     $26.5 million, a decrease of $15.0 million from the prior year
     period and a decrease of $4 million from the previous quarter. 
     Net sales for the three months ended December 31, 1995 were $24.5
     million, a decrease of $13.3 million from the prior year quarter
     and a decrease of $2 million from the previous quarter. Net sales
     for the three months ended March 31, 1996 were $26.2 million, a
     decrease of $4.2 million from the prior year period but an
     increase of $1.7 million from the previous quarter.  As a result
     of the distractions and uncertainties associated with the Acqui-
     sition, net sales for the quarter ended June 30, 1996 are expect-
     ed to be the lowest quarterly revenues for the fiscal year ended
     June 30, 1996.  The decline in net sales was largely the result
     of the anticipated decline in sales of proprietary systems,
     including reduced shipments under the U.S. Department of
     Commerce's Next Generation Weather Radar (NEXRAD) program without
     a corresponding  increase in the sales of open systems. Declining
     sales of computer systems consequently results in fewer mainte-
     nance contracts. This, together with a decline in renewal rates
     on maturing maintenance contracts as installed systems are
     decommissioned and competitive discounting from third party
     maintenance providers, has led to a declining trend in service
     revenues.

          The future growth of Concurrent's business and its future
     financial performance will depend on, among other things, its
     ability to increase net sales by continuing to develop and market
     competitive real-time open systems products and to expand its
     revenue base through a combination of internal growth and strate-
     gic alliances.  There can be no assurance as to the future growth
     of Concurrent's business and financial performance or as to the
     success of its products and strategic alliances.

     HISTORY OF OPERATING LOSSES; ACCUMULATED DEFICIT

          For the nine months ended March 31, 1996 and for the fiscal
     years ended June 30, 1995 and 1994, Concurrent experienced losses
     (before extraordinary items and the cumulative effect of changes
     in accounting principles) of approximately $5.7 million, $2.0
     million and $11.6 million, respectively.  Concurrent recorded net
     income of $3.9 million for the fiscal year ended June 30, 1993. 
     Pro forma to reflect the Acquisition, Concurrent would have
     experienced losses of approximately $7.6 million and $7.4 million
     for the nine months ended March 31, 1996 and the fiscal year
     ended June 30, 1995, respectively, assuming the Acquisition were
     consummated at the beginning of each such period.  There can be
     no assurance that Concurrent will be able to achieve profitabili-
     ty, or if achieved, that such profitability can be maintained.

          For the nine months ended March 31, 1996 and for the fiscal
     years ended June 30, 1995, 1994 and 1993, Concurrent also experi-
     enced a decline in assets.  On a pro forma basis as of March 31,
     1996, as a result of the Acquisition, Concurrent would have had
     assets of approximately $109.5 million, including its CyberGuard
     Stock (see "Pro Forma Condensed Consolidated Financial Statements
     of Concurrent" in the Joint Proxy Statement incorporated by
     reference herein).  The pro forma consolidated balance sheet at
     March 31, 1996 does not reflect certain restructuring adjustments
     which may result from the integration of the Concurrent and
     CyberGuard real-time businesses, such as the write-down of the
     carrying value of property, plant and equipment which may become
     excess to the needs of Concurrent.  Such writedowns may exceed
     $10 million.  There can be no assurance that Concurrent's assets
     will not continue to decline. 

     POTENTIAL SHORTFALL IN LIQUIDITY

          Although the purchase of the CyberGuard real-time business
     and the integration and consolidation of development and manufac-
     turing operations is expected to improve Concurrent's liquidity
     by permitting additional borrowing availability, there can be no
     assurance that cash flow from the combined real-time operations
     will be sufficient to fund transaction costs related to the
     Acquisition including relocation of Concurrent's operations to
     Florida, anticipated restructuring costs, and ongoing working
     capital requirements. Concurrent's liquidity is dependent on many
     factors, including sales volume, operating profit ratio, debt
     service and the efficiency of asset use and turnover.  The future
     liquidity of Concurrent will depend to a significant extent on
     (i) the actual versus anticipated decline in sales of proprietary
     systems and service maintenance revenue; (ii) revenue growth from
     open systems; (iii) both the related costs and the length of time
     to realize the anticipated benefits from the integration of the
     real-time businesses of Concurrent and CyberGuard; and (iv)
     ongoing cost control actions.  Liquidity will also be affected
     by:  (i) the timing of shipments, which predominantly occur
     during the last month of the quarter; (ii) the increasing per-
     centage of sales derived from outside the United States, where
     there are generally longer accounts receivable collection cycles
     and which receivables are not included in Concurrent's borrowing
     base under its revolving credit facility; (iii) the sales level
     in the United States, where related accounts receivable are
     included in the borrowing base of Concurrent's revolving credit
     facilities; and (iv) the number of countries in which Concurrent
     will operate, which may require maintenance of minimum cash
     levels in each country and, in certain cases, may restrict the
     repatriation of cash, such as cash held on deposit to secure
     office leases.  

          Concurrent may sell or pledge some or all of the CyberGuard
     Stock to generate cash.  To the extent CyberGuard consummates a
     public offering of its stock, Concurrent intends to sell at least
     one-half of the shares of CyberGuard Stock owned by it in connec-
     tion with such public offering.  On May 23, 1996, Cyberguard
     filed a registration statement relating to a public offering of
     2,500,000 million shares of its common stock of which 1,800,000
     shares are being offered by Cyberguard, 341,589 are being offered
     by Concurrent and the balance are being offered by other selling
     stockholders.  In addition, under the terms of the agreements
     relating to the Acquisition, Concurrent may sell a portion of its
     stock even if a public offering is not consummated.  However,
     Concurrent's ability to sell or pledge the  CyberGuard Stock is
     subject to a number of limitations and conditions pursuant to the
     terms of the Acquisition.  See "Terms Of The Transaction -- The
     Share Holding Agreement" of the Joint Proxy Statement incorporat-
     ed herein by reference.  These limitations and conditions may
     affect Concurrent's flexibility in generating cash through sales
     of CyberGuard Stock.

          Concurrent anticipates that the capital resources available
     will be adequate to satisfy its capital requirements through June
     1997, assuming quarterly net sales of the combined real-time
     businesses in the range of $30 million.  Concurrent's future
     capital requirements, however, will depend on many factors,
     including its ability to successfully market and sell its commer-
     cial products, the cost and timing of the integration of the
     real-time businesses of Concurrent and CyberGuard to realize
     potential synergies and cost savings and the cost of developing,
     marketing and selling competitive products.  To the extent that
     the funds generated by operations are insufficient to satisfy
     Concurrent's capital requirements, Concurrent may seek additional
     equity or debt financing or obtain additional credit facilities. 
     Any equity or debt financing, if available at all, may be on
     terms which are not favorable to Concurrent and, in the case of
     equity or convertible debt offerings, could result in dilution to
     Concurrent's then existing stockholders.  Concurrent is also
     considering various additional financing alternatives, including
     a possible sale or sale and partial leaseback of its Oceanport,
     New Jersey facility to improve its financial flexibility.  If
     adequate funds are not available, Concurrent may be required to
     curtail certain activities, including product development,
     marketing and sales activities. 

     POTENTIALLY ADVERSE CUSTOMER REACTION

          While Concurrent believes that its customers generally favor
     the Acquisition due to the broader product line of Concurrent and
     the other operational benefits of the Acquisition, there can be
     no assurance as to such customer reaction.  Adverse reactions by
     Concurrent customers could have a material adverse effect on the
     financial performance, results of operations and financial
     condition of Concurrent.  

     LAG IN CUSTOMER ORDERS; LONG SALES CYCLE

          Although Concurrent pursues significant programs with the
     potential for high volume unit sales of its systems, it neither
     has nor relies on fixed term or fixed quantity contracts for
     future sales.  Consequently, Concurrent relies on customer orders
     in a given quarter for net sales for the quarter and on internal
     forecasts of customer demand to plan operating expenditures.  The
     internal forecasts generally have proven to be optimistic.  The
     ability to match expenditures to anticipated sales is further
     complicated by the trend of a majority of customers to delay
     orders to the last month of a quarter.  Further, the manufacture
     of systems in anticipation of firm orders introduces the risk of
     over-production and investing limited cash resources in potential
     excess inventory.  As a result, substantial efforts must be
     undertaken on a continuous basis to maintain existing levels of
     business and to manage expenditures consistent with anticipated
     sales.

          The sale of real-time products generally involves signifi-
     cant education and commitment of capital by prospective custom-
     ers, with the attendant delays frequently associated with large
     capital expenditures and lengthy procurement procedures.  For
     these and other reasons, the expected sales cycle associated with
     the sale of Concurrent's products is typically long and subject
     to a number of significant risks over which Concurrent does not
     have significant control.  As a result, Concurrent may expend
     significant resources pursuing potential sales that will not be
     consummated, which in turn result in decreased revenues and cash
     flow, potentially resulting in a material adverse effect on the
     financial performance, results of operations and financial
     condition of Concurrent.

     SHIFT IN EMPHASIS AWAY FROM PROPRIETARY SYSTEMS

          Many of Concurrent's target markets have undergone or are
     undergoing a shift away from "proprietary" to "open" systems. 
     Sales related to Concurrent's proprietary systems, while declin-
     ing, continue to represent more than 50% of its total systems
     sales.  Concurrent had approximately $25 million in open system
     sales and $47 million in proprietary systems sales in its fiscal
     year ended June 30, 1995 and $15 million in open systems sales
     and $21 million in proprietary systems sales for the nine months
     ended March 31, 1996.  Although Concurrent's installed base of
     proprietary systems is currently its largest market, Concurrent's
     growth and its long-term financial performance will depend
     largely on its ability to continue to develop and market industry
     leading open systems that meet the real-time computing needs of
     its targeted customers.  Concurrent plans to capitalize on the
     trend to open systems by focusing on its target markets as well
     as entering into strategic alliances with third parties to bring
     to market new solutions and software applications for new and
     existing customers.  Concurrent does not expect the shift in
     emphasis to open systems to result in either significant incre-
     mental costs over current cost levels or incremental capital
     investment.  A shift in emphasis to open systems may, however,
     result in lower gross margins on systems sales.  Currently, gross
     margins on open systems are lower than gross margins on propri-
     etary systems.  Concurrent's operating income would be adversely
     affected by such a shift unless total net sales increase, the
     gross margins on its open systems improve and/or total operating
     expenses are reduced.

          Servicing Concurrent's large installed base, particularly
     its proprietary systems, is an important element in Concurrent's
     business strategy and generates significant revenue and cash flow
     to Concurrent.  The shift in emphasis to open systems may also
     have an adverse impact on maintenance revenues.  Generally, open
     systems require less maintenance and can, in many cases, be
     serviced by the customers themselves or by third party providers. 
     For Concurrent, the shift in emphasis, together with declining
     systems sales, resulted in the decline of service revenue from
     $87.6 million for the year ended June 30, 1993 to $68.1 million
     for the year ended June 30, 1995, respectively.  For the nine
     months ended March 31, 1996, Concurrent's service revenue was
     $41.4 million compared to $51.8 million in the prior year period. 
     There can be no assurance that the decline in service revenue
     will not continue.  Should such decline continue, Concurrent's
     operating income would be adversely affected by such a decline
     unless non-service revenues increase and/or total operating
     expenses are reduced.

     PRODUCT OBSOLESCENCE; SIGNIFICANT RESEARCH AND DEVELOPMENT EXPENDITURES

          The information technology industry is characterized by
     rapid advances in technology and demand for more cost effective
     "solutions."  The technologies incorporated by Concurrent into
     its products and future products are in a continuous state of
     development and tend to be surpassed by new developments within
     18-24 months of initial commercial use.  Continued rapid advances
     in technology will further accelerate the technological obsoles-
     cence of these products as well as those of Concurrent's competi-
     tors, which may affect Concurrent's financial performance,
     results of operations and financial condition.  Concurrent's
     success will depend, to a significant extent, upon the ability to
     enhance existing products, to integrate the best technologies of
     Concurrent and CyberGuard and to introduce new products and
     features in a timely manner to meet changing customer require-
     ments.  It will also be dependent on the success of strategic
     technological alliances.  In order to accomplish these objec-
     tives, Concurrent must maintain certain levels of investment in
     research and development and effectively use this investment. 
     Concurrent must obtain and incorporate new hardware, software,
     communications and peripheral technologies that are primarily
     developed by others.  There can be no assurance that the new
     product development activities will be successful, that new
     technologies will be available to Concurrent, that it will be
     able to deliver commercial products in a timely manner or that
     its products will achieve market acceptance.  The business of
     Concurrent will be adversely affected if it, its strategic
     partners, or its suppliers incur delays in developing new prod-
     ucts or enhancements, or if such products or enhancements do not
     gain market acceptance because of competing technology.  In
     addition, some new product introductions are intended to replace
     existing products.  Although reasonable commercial efforts will
     be made to monitor and manage new product introductions, there
     can be no assurance that a new product introduction will not
     result in a material amount of obsolete inventory.  Consequently,
     there may be a material adverse effect on liquidity of Concurrent
     in the event there is significant inventory that Concurrent is
     unable to dispose of in a reasonable time frame at an aggregate
     value approximately equal to its aggregate book value.  There can
     be no assurance that new product introductions will be executed
     without a material adverse effect on the financial performance,
     results of operations or the financial condition of Concurrent. 
     The costs of developing future products in the real-time comput-
     ing and multimedia markets is expected to be significant.  While
     Concurrent's real-time computing sectors are well developed and
     have an extensive operational history, its multimedia sector is
     in the relatively early stages of market development and is
     likely to require extensive development, sales and marketing
     expense before it may be in a position to contribute significant
     revenue or cash flow.  There can be no assurance as to the cost
     of funding future products in either product sector or on the
     ability of these product sectors to contribute to the revenues or
     cash flows of Concurrent.

     NEED TO ESTABLISH ADDITIONAL MARKETING RELATIONSHIPS

          A significant business strategy of Concurrent is to enter
     into strategic marketing alliances or other similar collaborative
     relationships.  There can be no assurance that existing or
     contemplated collaborative relationships will be commercially
     successful, that Concurrent will be able to negotiate additional
     collaborative relationships, that such additional collaborations
     will be available to Concurrent on acceptable terms or that any
     such relationships, if established, will be commercially success-
     ful.  The potential increased revenues from such relationships
     may be reduced by requirements to provide volume price discounts
     and other allowances, and potential significant costs incurred in
     customizing products.  In addition, there can be no assurance
     that parties with whom collaborative relationships are estab-
     lished will not pursue alternative technologies or develop
     alternative products in addition to or in lieu of Concurrent's
     products, either on their own or in collaboration with others,
     including Concurrent's competitors.  Such alternative technolo-
     gies or products, if developed, may be in direct competition with
     Concurrent's technologies or products and may significantly erode
     the benefits of such strategic marketing alliances or collabora-
     tive relationships.

     LIMITED PROTECTION OF INTELLECTUAL PROPERTY AND PROPRIETARY
     RIGHTS; RISK OF LITIGATION; RELIANCE ON LICENSED TECHNOLOGY

          Concurrent relies on patent, trademark, copyright and trade
     secret laws, employee and third-party non-disclosure agreements
     and other methods to protect its rights.  Concurrent holds
     patents and may apply for patents which cover certain aspects of
     its technology.  There can be no assurance that any pending or
     future patent applications will be granted or that any current or
     future patents will not be challenged, invalidated or circumvent-
     ed or that the rights granted thereunder will provide competitive
     advantages to Concurrent.  There can be no assurance that Concur-
     rent s trade secrets or non-disclosure agreements will provide
     meaningful protection of its proprietary information.  Further-
     more, there can be no assurance that others will not independent-
     ly develop similar technologies or duplicate any technology
     developed by Concurrent or that the technology will not infringe
     upon patents or other rights owned by others.  Further, Concur-
     rent may be subject to risk as it enters into transactions in
     countries where intellectual property laws are not well developed
     or are poorly enforced.  Legal protections of Concurrent's rights
     may be ineffective in such countries, and technology developed in
     such countries may not be protectable in jurisdictions where
     protection is ordinarily available.  Concurrent s inability to
     maintain a competitive advantage based on proprietary rights
     would have a material adverse effect on its financial perfor-
     mance, results of operations and financial condition.

          As the number of real-time computing products in the indus-
     try increases and the functionality of these products further
     overlaps, software developers and publishers may increasingly
     become subject to infringement claims.  There can be no assurance
     that third parties will not assert infringement claims against
     Concurrent in the future with respect to current or future
     products.  There has been substantial litigation regarding
     patent, copyright, trademark and other intellectual property
     rights involving computer companies generally.  Concurrent has
     been separately notified by IBM and BTG (British Technology
     Group), that each believes that certain of Concurrent s technology 
     may infringe on certain patents held by their respective
     companies.  These and any claims or litigation, with or without
     merit, could be costly and could result in a diversion of manage-
     ment s attention, which could have a material adverse effect on
     Concurrent's financial performance, results of operations and
     financial condition.  Adverse determinations in such claims or
     litigation could also have a material adverse effect on
     Concurrent's financial performance, results of operations and
     financial condition.

          From time to time, other companies and individuals assert
     exclusive patent, copyright, trademark and other intellectual
     property rights to technologies or marks that are important to
     the computer industry or Concurrent's business.  Concurrent
     evaluates each claim relating to its products and, if appropri-
     ate, seeks a license to use the protected technology.  The
     licensing agreements generally do not protect Concurrent from
     trade secret, copyright or other violations by Concurrent or its
     suppliers in developing or selling these products.  There can be
     no assurance, however, that Concurrent will be able to obtain
     licenses to intellectual property of third parties on commercial-
     ly reasonable terms, if at all.  In addition, Concurrent could be
     at a disadvantage if its competitors obtain licenses for protect-
     ed technologies with more favorable terms than does Concurrent. 
     If Concurrent or its suppliers are unable to license protected
     technology used in its products, Concurrent could be prohibited
     from marketing those products or may have to market products
     without desirable features.  Concurrent could also incur substan-
     tial costs to redesign its products or to defend any legal action
     taken against it.  If Concurrent's products should be found to
     infringe protected technology, it could be enjoined from further
     infringement and required to pay damages to the infringed party.

     RELIANCE ON GOVERNMENT BUSINESS

          Concurrent derives a significant portion of its revenues
     from the supply of systems under government contracts.  For its
     fiscal year ended June 30, 1995, approximately $39.2 million of
     Concurrent's revenues were directly or indirectly related to
     agencies of the U.S. Government.  This amount represented approx-
     imately 28% of Concurrent's worldwide revenues for fiscal year
     1995, compared to 31% and 29% for its 1994 and 1993 fiscal years,
     respectively.  For the nine months ended March 31, 1996, approxi-
     mately $14 million (18%) of Concurrent s revenues were directly
     or indirectly related to agencies of the U.S. Government. 
     Concurrent's revenues related to sales to the U.S. Government are
     derived from various federal agencies, no one of which accounted
     for more than 5% of total revenues (e.g., several agencies
     participate under the NEXRAD program).  Sales to Unisys Corp., as
     prime contractor, under the NEXRAD program contributed approxi-
     mately $17.5 million, $23 million and $35 million in revenues for
     fiscal years 1995, 1994 and 1993, respectively.  The program is
     largely completed and no significant revenue is expected for
     future periods.  Government business is, in general, subject to
     special risks, such as delays in funding, termination of con-
     tracts or subcontracts for convenience of the government or for
     default by the contractor, reduction or modification of contracts
     or subcontracts, failure to exercise options, changes in govern-
     mental policies and the imposition of budgetary constraints.  A
     loss of government contract revenues could have a material
     adverse effect on the financial performance, results of opera-
     tions and financial condition of Concurrent.

     DEPENDENCE ON INTERNATIONAL OPERATIONS

          The financial results of Concurrent are increasingly depen-
     dent on its international operations.   Approximately 46% of
     total revenues for its fiscal year 1995 were derived from inter-
     national operations. For the nine months ended March 31, 1996,
     approximately 51% of total revenues were derived from interna-
     tional operations.  Concurrent expects international operations
     to continue to account for a significant percentage of total
     revenues.  Certain risks are inherent in international opera-
     tions, including exposure to currency fluctuations, the imposi-
     tion of government controls, export license requirements, re-
     strictions on the export of critical technology, political and
     economic instability, trade restrictions, changes in tariffs,
     taxes and freight rates, generally longer payment cycles, diffi-
     culties in staffing and managing international operations and
     general economic conditions.  From time to time in the past,
     financial results of Concurrent have been affected both favorably
     and unfavorably by fluctuations in currency exchange rates. 
     Future unfavorable fluctuations in currency exchange rates may
     have an adverse impact on the financial performance, results of
     operations and financial condition of Concurrent.  Although
     international revenues continue to represent an increasing
     percentage of total revenues, accounts receivable from such
     international revenues are not included in the borrowing base
     under Concurrent's revolving credit facility.

     COMPETITION

          Concurrent operates in highly competitive environments
     driven by rapid technological innovation.  Many of its competi-
     tors have greater financial and operating resources.  In addi-
     tion, companies with greater resources that currently do not
     compete may enter into various of the company's target business-
     es.  The success of Concurrent will depend in part upon the
     ability of its management to demonstrate to potential customers
     the performance and reliability of its products and services. 
     There can be no assurance that management will be successful in
     these efforts.

          An increase in competition could result in, among other
     things, price reductions and loss of sales volume. Such competi-
     tion and any resulting reduction in aggregate revenues and/or
     gross margins could have a material adverse effect on the future
     financial performance, results of operations and financial
     condition of Concurrent.  There can be no assurance that
     Concurrent's competitors will not develop real-time products that
     may be more effective than Concurrent's current or future prod-
     ucts or that Concurrent's technologies and products will not be
     rendered obsolete by such developments.

     LIMITED SOURCES OF SUPPLY

          In limited cases, Concurrent purchases components from a
     single supplier to obtain the required technology and the most
     favorable price and delivery terms.  Concurrent estimates that a
     lead time of up to 16-24 weeks may be necessary to switch to an
     alternative supplier of certain custom application specific
     integrated circuits ("ASICS") and printed circuit assemblies.  A
     change in the supplier of these components without the appropri-
     ate lead time could result in a material delay in shipments by
     Concurrent of certain products and possibly, a material adverse
     effect on the financial performance, results of operations and
     financial condition of Concurrent.  

          Concurrent purchases components, including customized
     components such as certain computer peripheral equipment incorpo-
     rated into NightHawk  computers, from a single supplier to obtain
     the required technology and the most favorable price and delivery
     terms.  This single supplier will continue to be relied upon by
     Concurrent.  In the manufacture of the current generation 6000
     series of NightHawk computers, Concurrent depends on the avail-
     ability of Power PC  chips provided by both IBM and Motorola.  In
     addition, the manufacturing process requires a high volume of
     quality components that are procured from third-party suppliers.

          Reliance on suppliers, as well as industry supply condi-
     tions, generally involve several risks, including the possibility
     of defective parts, a shortage of components, increase in compo-
     nent costs, and reduced control over delivery schedules, any or
     all of which could adversely affect Concurrent's respective
     financial results.  Where alternative sources are available,
     qualification of the alternative suppliers and establishment of
     reliable supplies of components from such sources may result in
     delays.  Problems with supplier performance or delays in delivery
     of components may cause a delay in shipments of various products. 
     Since revenue is recognized typically upon shipment, any delay in
     shipment may also result in a delay in revenue recognition,
     possibly outside the fiscal period originally planned, and, as a
     result, may adversely affect financial results for that particu-
     lar period.  

     POTENTIAL NEED TO EXPAND INFRASTRUCTURE

          If Concurrent experiences rapid growth, of which there can
     be no assurance, it will need to continue to improve and expand
     its infrastructure.  There can be no assurance that Concurrent
     will be able to manage expansion of its infrastructure to support
     future growth effectively, if required.  Concurrent expects to
     transition its management information systems to more fully
     integrate them on an enterprise wide basis, to reduce redundancy
     and to incorporate enhanced functionality.  There can be no
     assurance that this management information system transition can
     be accomplished on a timely basis or without disruptions of
     Concurrent's operations, or management information functions,
     which could have a material adverse effect on Concurrent's
     financial performance, results of operations and financial
     condition.

     DEPENDENCE ON KEY EMPLOYEES

          As a high technology company in a highly competitive indus-
     try, the success of Concurrent depends in part on its ability to
     attract and retain highly skilled technical, managerial, sales
     and marketing employees.  Competition for these key employees is
     intense.  The uncertainty as to which employees will remain as
     part of Concurrent and the locations of various functions in
     connection with the integration of the CyberGuard real-time
     business as well as other factors beyond Concurrent's control may
     lead certain employees to choose alternative employment.  Al-
     though Concurrent is not dependent on any one employee, the loss
     of a number of key employees in significant positions and the
     inability to attract and retain qualified replacement employees
     in a timely manner could adversely affect the financial perfor-
     mance, results of operations and financial condition of Concurrent.

     DIVIDEND POLICY

          It is currently contemplated that Concurrent will not pay
     cash dividends on the Common Stock in the immediately foreseeable
     future.  Concurrent's dividend policy will be reviewed by its
     Board of Directors at such future time as may be appropriate in
     light of relevant factors existing at such times. 

     CERTAIN BARRIERS TO CHANGES OF CONTROL; EFFECTS OF CHANGES OF CONTROL

          Rights associated with Common Stock may have the effect of
     discouraging a third party from making an acquisition proposal to
     Concurrent, and may thereby inhibit a change in control of the
     company in circumstances that could give the holders of Common
     Stock the opportunity to realize a premium over the then prevail-
     ing market price.  Such provisions may also adversely affect the
     market price of Common Stock.  In addition, loans under certain
     credit agreements may be accelerated at the option of the lenders
     in the event of a "change in control" of Concurrent (as that term
     is defined in the credit agreements governing such loans).  The
     charter and by-laws of Concurrent and the Delaware General
     Corporation Law (the "DGCL") contain certain provisions that may
     have the effect of inhibiting a non-negotiated merger or other
     business combination.

          The Board of Directors of Concurrent has the authority to
     issue shares of preferred stock and to determine the designa-
     tions, preferences, and rights and the qualifications or restric-
     tions of those shares without any further vote or action by the
     stockholders.  The rights of the holders of Common Stock will be
     subject to, and may be materially adversely affected by, the
     rights of the holders of any preferred stock that may be issued
     in the future.  The issuance of preferred stock, while providing
     desirable flexibility in connection with possible acquisitions
     and other corporate actions, could have the effect of making it
     more difficult for a third party to acquire, or of discouraging a
     third party from acquiring, as the case may be.  With the excep-
     tion of the Convertible Preferred Stock issued to CyberGuard,
     Concurrent has no present plan to issue shares of preferred
     stock.

     LIMITATIONS ON THE USE OF CERTAIN TAX LOSS CARRYFORWARDS

          Concurrent has substantial tax loss carryforwards available
     to offset future taxable income.  Under Section 382 of the
     Internal Revenue Code of 1986, as amended (the "Code"), the use
     of Concurrent's tax loss carryforwards could be limited in the
     event of an "ownership change" involving more than 50% of
     Concurrent's stock, including ownership changes arising by reason
     of stock issuances by Concurrent.  Although Concurrent has issued
     a significant amount of stock in connection with the Acquisition,
     the "ownership shift" resulting from such issuance, when coupled
     with other ownership shifts involving certain 5% stockholders of
     Concurrent since July 21, 1993, is not sufficient to constitute a
     50% ownership change within the meaning of Section 382 of the
     Code.  Accordingly, the Acquisition has not impaired the avail-
     ability of these tax loss carryforwards to Concurrent.  It is
     possible, however, that future ownership shifts involving the
     stock of Concurrent could limit its ability to use these tax loss
     carryforwards, including changes which occur by reason of addi-
     tional stock issuances by Concurrent or acquisitions or disposi-
     tions of Common Stock by persons who are or become owners of 5%
     or more of Common Stock.

     ANTI-TAKEOVER PROVISIONS

          Concurrent has adopted and implemented a Rights Agreement
     that will expire by its terms on August 14, 2002 pursuant to
     which each share of Common Stock has attached to it a right to
     purchase a share of preferred stock under certain circumstances. 
     This agreement is intended to encourage a person interested in
     acquiring Concurrent to negotiate with, and to obtain the approv-
     al of, the Board of Directors in connection with such a transac-
     tion.  However, this agreement may discourage a future acquisi-
     tion of Concurrent, including an acquisition in which stockhold-
     ers might otherwise receive a premium for their shares.  As a
     result, stockholders who might desire to participate in such a
     transaction may not have the opportunity to do so.

                 CERTAIN ARRANGEMENTS WITH BERENSON MINELLA

          In June 1995, Concurrent engaged Berenson Minella as its
     financial advisor to assist senior management in restructuring
     and/or refinancing Concurrent's bank debt and to explore various
     options with respect to raising capital and combination transac-
     tions with other parties  As part of such engagement, Berenson
     Minella acted as Concurrent's financial advisor in connection
     with the Acquisition.

          Since June 1995, Berenson Minella has received fees total-
     ling $280,000 for its financial advisory services to Concurrent. 
     In connection with the Acquisition, Concurrent agreed to pay
     Berenson Minella a transaction fee of $_______, equal to 1.5% of
     the average aggregate value of the outstanding Common Stock (as
     of the close of business) for the five business days prior to the
     date of consummation of the Acquisition (the "Closing Price"),
     against which fee $_______ of the amount previously paid was
     credited.  Of such fee, $300,000 was paid at the closing of the
     Acquisition (offset by previously paid retainer fees as described
     in the preceding sentence), and the remainder of $_______ (the
     "Remainder Amount") is payable by delivery to Berenson Minella of
     the proceeds from the sale by Concurrent at the direction of
     Berenson Minella of the 412,000 shares of Common Stock offered
     hereby; provided, however, that if the aggregate net proceeds
     from the sale of the shares are less than the Remainder Amount,
     Concurrent has agreed to pay Berenson Minella the amount of the
     difference in cash on or before the twenty-fifth business day
     following the closing of the Acquisition or, if Berenson Minella
     so elects, to deliver such unsold shares to Berenson Minella,
     which shares would be unregistered and without registration
     rights.  Concurrent will sell up to 412,000 of the shares of
     Common Stock offered hereby only as directed by Berenson Minella
     and will not be entitled to any of the proceeds therefrom.  See
     "Plan of Distribution."  Pursuant to the terms of the engagement,
     the number of shares was determined by using a price per share
     equal to the product of (i) the Closing Price and (ii) .875. 
     Concurrent has also agreed to reimburse Berenson Minella for its
     reasonable out of pocket expenses (including the fees and expens-
     es of its counsel) and to indemnify Berenson Minella and certain
     related persons against certain liabilities and expenses in
     connection with its services as financial advisor and the sale of
     the 412,000 shares of Common Stock in connection with the compen-
     sation therefor, including liabilities under federal securities laws.

                            PLAN OF DISTRIBUTION

          The distribution of the shares of Common Stock is not
     subject to any underwriting agreement. Any or all of the shares
     of  Common Stock offered hereby may be offered and sold to
     purchasers directly by or on behalf of Concurrent from time to
     time in the over-the-counter market, in privately negotiated
     transactions, or otherwise at prices prevailing in such market or
     as may be negotiated at the time of the sale.  With respect to
     412,000 of the shares of Common Stock offered hereby, Concurrent
     has, at the direction of Berenson Minella, designated Bear,
     Stearns & Co., Inc. ("Bear Stearns") as the selling agent.  An
     account has been established at Bear Stearns for the benefit of
     Berenson Minella.  Concurrent, upon notification by Berenson
     Minella, will direct the sale of the 412,000 shares by Bear
     Stearns.  To the extent that the aggregate net proceeds generated
     from the sale of the shares of Common Stock exceed the Remainder
     Amount, Berenson Minella will retain such excess proceeds in
     accordance with the terms of its fee arrangement with Concurrent. 
     Bear Stearns will earn an agency fee of $[.02] per share of Common
     Stock sold.  Alternatively, Bear Stearns, which is a market-maker
     in the Common Stock, may act as principal in the purchase of such
     shares.

          With respect to the severance obligation of $730,000 to Mr.
     Stihl, Concurrent has appointed A.G. Edwards Inc. ("A.G. Ed-
     wards") as its selling agent to sell up to 238,000 shares of
     Common Stock as directed by Mr. Stihl.  Aggregate net proceeds in
     excess of $730,000 from the sale of such shares will be retained
     by Concurrent in accordance with the terms of the employment
     agreement between Concurrent and Mr. Stihl.  If the proceeds from
     the sale of such shares are insufficient to satisfy the $730,000
     severance obligation, Concurrent will allocate additional shares
     of Common Stock to be sold by A.G. Edwards as selling agent as
     directed by Mr. Stihl.  A.G. Edwards will earn an agency fee of
     $.02 per share of Common Stock sold. 

          With respect to the remaining shares of Common Stock,
     Concurrent has appointed Smith Barney Inc. ("Smith Barney") as
     selling agent.  An account has been established at Smith Barney
     by Concurrent on behalf of the former executive officers of
     Concurrent (other than Mr. Stihl) entitled to severance pursuant
     to the terms of the Acquisition.  Concurrent will direct the sale
     of such shares of Common Stock as are necessary to fund the
     severance obligations owed to the former executive officers.  The
     aggregate net proceeds from such sales of shares of Common Stock
     will be allocated proportionately to each individual executive
     officer by means of sub-accounts that have been established by
     Concurrent at Smith Barney for the benefit of each such former
     executive officer.  Smith Barney will earn an agency fee of $.02
     per share of Common Stock sold.  Alternatively, Smith Barney,
     which is a market-maker in the Common Stock, may act as principal
     in the purchase of such shares. 

          To the extent that the aggregate net proceeds from the sale
     of shares of Common Stock are insufficient to fund the obliga-
     tions to Mr. Stihl or the executive officers, Concurrent may use
     cash or register additional shares of Common Stock for sale
     pursuant to a new registration statement.

          Agents that participate in the distribution of shares of the
     Common Stock may be deemed to be underwriters, and any profit on
     the sale of the shares of the Common Stock by them and any
     commissions received by them may be deemed to be underwriting
     discounts and commissions under the Securities Act.  The agents
     may also engage in other transactions with, and perform services
     for, Concurrent.  At the time a particular offer of the shares of
     Common Stock is made, to the extent required, a supplement to
     this Prospectus will be distributed which will set forth the
     aggregate number of shares of Common Stock being offered, and the
     terms of the offering, the name or names of any agents, any
     underwriting discounts or commissions and other items constitut-
     ing compensation from, and the resulting net proceeds to, Concur-
     rent, any discounts, commissions or concessions allowed or
     reallowed or paid to dealers and, if applicable, the purchase
     price to be paid by any underwriter for shares of Common Stock
     purchased from Concurrent.

          In order to comply with the securities laws of certain
     states, sales of shares of the Common Stock to the public in such
     states may be made only through broker-dealers who are registered
     or licensed in such states.  Sales of shares of the Common Stock
     must also be made by the Concurrent in compliance with other
     applicable state securities laws and regulations.

          In connection with Berenson Minella's engagement as finan-
     cial advisor to Concurrent, Concurrent has agreed to indemnify
     Berenson Minella and each other person, if any, who controls
     Berenson Minella within the meaning of the Securities Act, and
     its respective directors, officers, partners, agents and affili-
     ates, against certain liabilities which may be incurred in
     connection with the sale of shares of Common Stock under this
     Prospectus.  The terms of the indemnification agreement also
     provide for rights of contribution if such indemnification is not
     available.

                               LEGAL OPINIONS

          The validity of the Common Stock offered hereby will be
     passed on for Concurrent by Skadden, Arps, Slate, Meagher & Flom,

     ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

          Section 145 of the Delaware General Corporation Law provides
     that a corporation may indemnify directors and officers as well
     as other employees and individuals against expenses (including
     attorneys' fees), judgments, fines and amounts paid in settlement
     in connection with specified actions, suits or proceedings,
     whether civil, criminal, administrative or investigative (other
     than an action by or in the right of the corporation - a "deriva-
     tive action"), if they acted in good faith and in a manner they
     reasonably believed to be in or not opposed to the best interests
     of the corporation, and, with respect to any criminal action or
     proceeding, had no reasonable cause to believe their conduct was
     unlawful.  A similar standard is applicable in the case of
     derivative actions, except that indemnification only extends to
     expenses (including attorneys' fees) incurred in connection with
     the defense or settlement of such action, and the statute re-
     quires court approval before there can be any indemnification
     where the person seeking indemnification has been found liable to
     the corporation.  The statute provides that it is not exclusive
     of other indemnification that may be granted by a corporation's
     charter, by-laws, disinterested director vote, stockholder vote,
     agreement or otherwise.  Article 23 of the Registrant's By-laws
     provides for indemnification of directors, officers, employees
     and agents of the Registrant for expenses (including attorneys'
     fees), judgments or fines of any threatened, pending or completed
     action, suit or proceeding.

          Article 11 of the Registrant's Certificate of Incorporation
     provides that directors shall not be liable for monetary damages
     resulting from a breach of their fiduciary duties, except for
     liability for any of the following:  (i) any breach of the duty
     of loyalty to the Registrant and its stockholders, (ii) acts or
     omissions not in good faith or which involve intentional miscon-
     duct or a knowing violation of law, (iii) as provided under
     Section 174 of the General Corporation Law of the State of
     Delaware (which provides that directors are personally liable for
     unlawful dividends or unlawful stock repurchase or redemptions),
     or (iv) any transaction from which a director personally derived
     any improper personal benefit.  If the Delaware General Corpora-
     tion Law is amended after approval by the stockholders of Article
     11 to authorize corporate action further eliminating or limiting
     the personal liability of directors, then the liability of a
     director of Concurrent shall be eliminated or limited to the
     fullest extent permitted by the Delaware General Corporation Law,
     as so amended from time to time.  Any repeal or modification of
     Article 11 shall not increase the personal liability of any
     director of Concurrent for any act or occurrence taking place
     prior to such repeal or modification, or otherwise adversely
     affect any right or protection of a director of Concurrent
     existing hereunder prior to the time of such repeal or modification.

          The Registrant maintains director and officer liability
     insurance policies providing for the insurance on behalf of any
     person who is or was a director or officer of the Registrant and
     subsidiary companies against any liability incurred by him in any
     such capacity or arising out of his status as such.  The
     insurers' limit of liability under the policies is $10,000,000 in
     the aggregate for all insured losses per year.  The policies
     contain various reporting requirements and exclusions.

          Effective January 31, 1996 Concurrent entered into indemnity
     agreements with its directors and executive officers (each, an
     "Indemnitee" and collectively, the "Indemnitees").  The indemnity
     agreements provide a contractual right to indemnification to the
     Indemnitees for certain expenses incurred due to actions, suits
     or other proceedings brought against them in their capacity as
     directors, officers, employees or agents of Concurrent or any of
     its subsidiaries.

     ITEM 17.  UNDERTAKINGS

               (a)    The undersigned registrant hereby undertakes:

                  (1)         To file, during any period in which
               offers or sales are being made, a post-effective amend-
               ment to this registration statement;

                  (i)         To include any prospectus required by
               Section 10(a)(3) of the Securities Act of 1933;

                  (ii)        To reflect in the prospectus any facts
               or events arising after the effective date of the
               registration statement (or the most recent post-effec-
               tive amendment thereof) which, individually or in the
               aggregate, represent a fundamental change in the infor-
               mation set forth in the registration statement.

                  (iii)       To include any material information with
               respect to the plan of distribution not previously
               disclosed in the registration statement or any material
               change to such information in the registration state-
               ment.

                  provided, however, that paragraphs (a)(1)(i) and
               (a)(1)(ii) do not apply if the information required to
               be included in a post-effective amendment by those
               paragraphs is contained in periodic reports filed with
               or furnished to the Commission by the Registrant pursu-
               ant to Section 13 or 15(d) of the Securities Exchange
               Act of 1934 that are incorporated by reference in the
               Registration Statement.

                  (2)         That, for the purpose of determining any
               liability under the Securities Act of 1933, each such
               post-effective amendment shall be deemed to be a new
               registration statement relating to the securities
               offered therein, and the offering of such securities at
               that time shall be deemed to be the initial bona fide
               offering thereof.

                  (3)         To remove from registration by means of
               a post-effective amendment any of the securities being
               registered which remain unsold at the termination of
               the offering.

               (b)    The undersigned registrant hereby undertakes
          that, for purposes of determining any liability under the
          Securities Act of 1933, each filing of the registrant's
          annual report pursuant to Section 13(a) or 15(d) of the
          Securities Exchange Act of 1934 (and, where applicable, each
          filing of an employee benefit plan's annual report pursuant
          to Section 15(d) of the Securities Exchange Act of 1934)
          that is incorporated by reference in the registration state-
          ment shall be deemed to be a new registration statement
          relating to the securities offered therein, and the offering
          of such securities at that time shall be deemed to be the
          initial bona fide offering thereof.

               (c)    Insofar as indemnification for liabilities
          arising under the Securities Act of 1933 may be permitted to
          directors, officers and controlling persons of the regis-
          trant pursuant to the foregoing provisions, or otherwise,
          the registrant has ben advised that in the opinion of the
          Securities and Exchange Commission such indemnification is
          against public policy as expressed in the Act and is, there-
          fore, unenforceable.  In the event that a claim for indemni-
          fication against such liabilities (other than the payment by
          the registrant of expenses incurred or paid by a director,
          officer or controlling person of the registrant in the
          successful defense of any action, suit or proceeding) is
          asserted by such director, officer or controlling person in
          connection with the securities being registered, the regis-
          trant will, unless in the opinion of its counsel the matter
          has been settled by controlling precedent, submit to a court
          of appropriate jurisdiction the question whether such indem-
          nification by it is against public policy as expressed in
          the Act and will be governed by the final adjudication of
          such issue.


                                 SIGNATURES

          Pursuant to the requirements of the Securities Act of 1933,
     the Registrant certifies that it has reasonable grounds to
     believe that it meets all of the requirements for filing on Form
     S-3 and has duly caused this Registration Statement to be signed
     on its behalf by the undersigned, thereunto duly authorized in
     the City of Oceanport, State of New Jersey, on June 6, 1996.

THIS AGREEMENT is made as of the 26th day of March 1996, and amended and
restated as of the 23th day of May 1996, between HARRIS COMPUTER SYSTEMS
CORPORATION, a Florida corporation ("Harris") and CONCURRENT COMPUTER
CORPORATION, a Delaware corporation ("Concurrent").

                   W I T N E S S E T H:

WHEREAS, Harris and its subsidiaries are engaged in the businesses of
providing and servicing high-performance real-time computer systems on a
worldwide basis (the "Business") and supplying "trusted products," including
operating systems and firewall application products (the "Trusted Systems
Business");

WHEREAS, Concurrent has agreed to purchase from Harris, and Harris has
agreed to sell to Concurrent, the Business and shares of common stock, par
value $0.01 per share, of Harris (the "Harris Common Stock") on the terms and
subject to the conditions set forth herein; and

WHEREAS, in exchange for the Business and such shares of Harris Common
Stock, Concurrent has agreed to sell to Harris, and Harris has agreed to
purchase from Concurrent, shares of common stock, par value $0.01 per share,
of Concurrent (the "Concurrent Common Stock") and shares of a new class of
convertible exchangeable preferred stock of Concurrent (the "Concurrent
Preferred Stock") on the terms and subject to the conditions set forth herein.

NOW, THEREFORE, the parties agree as follows:

                        ARTICLE I

               SALE AND PURCHASE OF ASSETS

Section 1.1 Transfer of Assets.

(a) Except as provided in Section 1.2, at the Closing, Harris shall sell,
transfer and assign to Concurrent, and Concurrent shall purchase, acquire
and/or accept from Harris, all of Harris' rights, title and interests in all
the Property (as defined below), of Harris which (i) is listed in Schedule
1.1(a)(i) (the "Identified Real Time Assets") and including the Property
identified on the Final Net Current Asset Reconciliation in existence on the
Closing Date; (ii) constitutes the Shared Assets (as defined in Section
1.1(b)) to the extent such Property is to be transferred and sold to, or
utilized by, Concurrent as provided in Schedule 1.1(b) (the "Shared Real Time
Assets"); (iii) constitutes all other Property of Harris which is not an
Excluded Asset (as defined in Section 1.2) (the "Other Real Time Assets");
(iv) is tangible Property which is manufacturing Property, hardware customer
support Property and hardware development Property; and (v) constitutes all
other Property of the kind described in clauses (i) and (ii) above and
acquired by Harris between the date hereof and the Closing (the "Subsequently
Acquired Real Time Assets"). The term "Property" shall mean assets, properties
and rights, tangible and intangible, wherever located.

(b) The term "Shared Assets" shall mean the Property of Harris having a
significant use in both the Business and the Trusted Systems Business. To the
extent they have been identified as of the date hereof, the Shared Assets are
set forth in Schedule 1.1(b), which Schedule indicates which of the therein
identified Shared Assets shall be transferred to Concurrent or retained by
Harris.

To the extent that any Shared Assets are not identified in Schedule
1.1(b), they shall be transferred to Concurrent at Closing or retained by
Harris as follows: (i) if the Shared Asset not identified in Schedule 1.1(b)
is a "Business Intellectual Property Right" (as defined in Section 4.16(a))
(each Shared Asset that is also a Business Intellectual Property Right, a
"Shared IP Right"), then each such asset shall be transferred as described in
the second sentence of this paragraph; and (ii) if the Shared Asset not
identified in Schedule 1.1(b) is not a Shared IP Right, then, unless
Concurrent acknowledges that such asset is not needed for the conduct of the
Business after the Closing, it shall be transferred to Concurrent. Shared IP
Rights that have not been identified in Schedule 1.1(b) shall be made
available by license or otherwise to Concurrent and Harris as follows: (i) if
the use of the Shared IP Rights does not require royalties or other payments
to be made to third parties, then the Shared IP Right shall be made available,
without cost, by license or otherwise so that each of Concurrent and Harris
may freely utilize such Shared IP Rights after Closing, subject to the terms
of the Non-Competition Agreement required to be delivered in accordance with
Section 2.4, and (ii) to the extent the use of the Shared IP Rights requires
royalties or payments to be made to third parties, Schedule 1.1(b) sets forth
the method by which such royalties or other payments will be borne by
Concurrent and Harris after the Closing.

(c) At the Closing, Harris shall sell, transfer and assign, directly or
indirectly, to Concurrent and Concurrent shall purchase, acquire and accept
from Harris, good and valid legal title to and beneficial ownership of all of
the issued and outstanding shares of capital stock (the "Harris Subsidiary
Shares"), free and clear of all Encumbrances (as defined in Section 4.21) or
assets, as the case may be, of certain subsidiaries to be mutually agreed upon
by the parties prior to Closing.

The subsidiaries, if any, to be transferred as agreed to by the parties
hereto shall be collectively referred to as the "Transferred Subsidiaries".
The shares shall constitute all of the issued and outstanding shares of each
such Transferred Subsidiary.

To the extent Concurrent purchases the stock of the Transferred
Subsidiaries, Concurrent shall not assume, and shall not be deemed to have
assumed, Liabilities of the Transferred Subsidiaries arising from activities
of the businesses of the Transferred Subsidiaries prior to Closing relating to
(i) environmental matters or (ii) claims of employees of the Transferred
Subsidiaries at the time of the applicable violation that the Transferred
Subsidiary violated employment practices laws, rules or regulations or
antidiscrimination laws, rules or regulations insofar as such claims are based
on acts or omissions that shall have occurred prior to Closing (the
"Transferred Subsidiaries Excluded Liabilities"). At Closing, Harris shall
assume, and shall be solely and exclusively liable with respect to the
Transferred Subsidiaries Excluded Liabilities.

(d) The term "Assets" shall mean the Identified Real Time Assets, the
Shared Real Time Assets, the Other Real Time Assets and the Subsequently
Acquired Real Time Assets, including the stock or assets, if any, of each of
the Transferred Subsidiaries, which will be being transferred by Harris to
Concurrent in accordance with Sections 1.1(a) and (b).

Section 1.2 Excluded Assets; Omitted Property.  (a) Concurrent is not
acquiring from Harris, and Harris shall retain ownership of all right, title
and interest in and to, and exclude from sale, transfer or assignment
hereunder (i) all Property of Harris used in the Trusted Systems Business
(other than Property which constitutes Shared Assets in accordance with
Section 1.1(b)) as conducted on the date hereof (the "Trusted Assets"); (ii)
the Trusted Assets listed in Schedule 1.2(a)(i) (the "Identified Trusted
Assets"), (iii) the Shared Assets, to the extent they shall be retained or
permitted to be utilized by Harris as provided in Schedule 1.1(b) (the "Shared
Trusted Assets").

(b) The term "Excluded Assets" shall mean the Trusted Assets, the
Identified Trusted Assets and the Shared Trusted Assets.

(c) The Parties hereto acknowledge that the Schedules of Assets and
Excluded Assets will not together contain a complete list of all Property of
Harris, but that at the Closing, the updated Schedules together with the lists
of Property attached to the bills of sale and other documents of transfer
delivered to Concurrent will list all the Assets as of the Closing. To the
extent that there is any Property of Harris as of the Closing which failed to
be identified on a Schedule of any Assets or Excluded Assets or on a list of
Property attached to the bill of sale or other document of transfer delivered
at Closing (the "Omitted Property"), it will be transferred, assigned, or sold
to Concurrent or retained or utilized by Harris in accordance with the Assets
or Excluded Assets to which such Omitted Property is most similar. Any
adjustments to the Final Net Asset Reconciliation which may be appropriate in
connection with such Omitted Property shall be made so long as, pursuant to
the terms hereof, the time period during which the parties hereto may dispute
the Final Net Asset Reconciliation (as defined in Section 2.3(b)) has not
elapsed.

Section 1.3 Assumed Liabilities; Excluded Liabilities.

(a) At the Closing, subject to Section 1.3(b) below, Concurrent shall

Closing Date; (ii) Liabilities arising from activities of the Business after
the Closing; (iii) Liabilities set forth on Schedule 1.3(a); (iv) Liabilities

defined in Section 6.24) hereof resulting from the transfer of the Assets
(other than the Harris Subsidiary Shares, if any) and 100% of the Transfer
Taxes resulting from the transfer of the Harris Subsidiary Shares, if any (the
"Assumed Concurrent Transfer Tax Liability") and (vii) the allocable portion
(the "Business Portion") of all Liabilities associated with both the Business
and the Trusted Systems Business (the "Shared Liabilities"), such portion to
be based on the Business' contribution to the total net revenues of Harris for
the fiscal year ended September 30, 1995 (items (i) through (vii),
collectively, the "Assumed Liabilities");

(b) Concurrent is not assuming, and shall not be deemed to have assumed,
any of the following Liabilities of Harris: (i) Liabilities exclusively
associated with the Trusted Systems Business; (ii) Liabilities arising from
activities of the Business prior to the Closing relating to environmental
matters, claims of shareholders of Harris, claims of employees of Harris at
the time of the applicable violation that Harris violated employment practices
laws, rules or regulations or antidiscrimination laws, rules or regulations
insofar as such claims are based on acts or omissions that shall have occurred
prior to Closing; (iii) the portion of the Shared Liabilities after the
assumption by Concurrent of the Business Portion of such Liabilities; (iv)
Liabilities in connection with any Taxes imposed upon Harris's operations set
forth in Schedule 1.3(b)(iv); and (v) all other Liabilities of Harris which

fixed or contingent, known or unknown as of the date hereof, and including
such liabilities or obligations under contracts and leases.

the exact effective time of the sale, transfer and assignment of the Assets
and the Harris Subsidiary Shares, and of the assumption of Assumed

party that an Audited Balance Sheet Disagreement is unable to be

the selection of a nationally recognized accounting firm, their
respective independent public accountants shall select such accounting
firm which shall be a firm other than KPMG, Coopers & Lybrand or Ernst &
Young. The determination of such firm shall be final and binding upon the
parties. Such firm shall render its determination as soon as practicable

Disagreement shall be paid by Concurrent and Harris as follows: 30% of
such fees shall be paid by the party whose position in the Audited
Balance Sheet Disagreement submitted to the arbiter is closest to the
final determination of the accounting firm selected, and the remaining
70% of such fees shall be paid by the other party.

(b) Net Current Asset Reconciliations.

(i) Not later than 5 business days prior to the Closing, Harris

Current Asset Reconciliation"). The Projected Net Current Asset
Reconciliation shall, except as set forth in this subsection (i), be
prepared in accordance with GAAP consistent with the accounting
principles used in preparation of the Audited Balance Sheet and prepared
in accordance with the additional procedures set forth in Schedule 2.3(b)
hereto. Harris shall cause KPMG to prepare promptly after the Reference
Date, but in no event more than 30 days following the Reference Date,
consistent with (i) the provisions of Schedule 2.3(b) and (ii) the
Projected Net Current Asset Reconciliation (to the extent it does not

Concurrent as of the Reference Date and the current liabilities of the
Business which were not retained by Harris as of the Reference Date (the
"Final Net Current Asset Reconciliation" and with the Projected Net Current 
Asset Reconciliation, the "Net Current Asset Reconciliations").

(ii) Following delivery of the Final Net Current Asset
Reconciliation, Harris shall promptly make available to Concurrent all
available work papers (including those relating to inventories and
accounts receivable) of KPMG created in connection with the preparation
of the Final Net Current Asset Reconciliation. Harris shall cause the
representatives of KPMG to be available to promptly assist Concurrent and
its auditors in its review of such work papers. In addition, in

(iii) Concurrent may dispute the Final Net Current Asset
Reconciliation by giving written notice to Harris within 30 days after
delivery of the Final Net Current Asset Reconciliation to Concurrent,
setting forth in reasonable detail the basis for such dispute
(hereinafter called a "Reconciliation Disagreement"). The parties shall
promptly commence good faith negotiations with a view to resolving such
Reconciliation Disagreement, which resolution shall be not later than 70
days after the Closing Date.

(iv) If Concurrent or Harris delivers a written notice to the other
party that a Reconciliation Disagreement is unable to be resolved, such
Reconciliation Disagreement shall be referred to a nationally recognized
accounting firm other than KPMG, Coopers & Lybrand or Ernst & Young for
determination of the disputed amounts in accordance with this Agreement.
If Concurrent and Harris do not promptly agree on the selection of a
nationally recognized accounting firm, their respective independent
public accountants shall select such accounting firm which shall be a
firm other than KPMG, Coopers & Lybrand or Ernst & Young. The
determination of such firm shall be final and binding upon the parties.
Such firm shall render its determination as soon as practicable after
referral of the Reconciliation Disagreement. The fees and expenses of
such firm with respect to a Reconciliation Disagreement shall be paid by
Concurrent and by Harris as follows: 30% of such fees shall be paid by
the party whose position in the Reconciliation Disagreement submitted to
the arbiter is closest to the final determination of the accounting firm
selected, and the remaining 70% of such fees shall be paid by the other
party.

(c) Adjustment to Preferred Stock Consideration.

(i) After delivery of the Projected Net Current Asset Reconciliation
and prior to the Closing, the Preferred Stock Consideration shall be
adjusted by reducing the total $10,000,000 liquidation preference and
stated value thereof, dollar for dollar, to the extent that total current
assets minus the total current liabilities (such difference, the "Net
Assets") shown on such Projected Net Current Asset Reconciliation is less
than $14,400,000. Such reduced amount of Preferred Stock Consideration,
if there shall be any reduction, shall be the actual amount of such
consideration delivered to Harris at the Closing.

(ii) After the Closing, additional reductions, if any, in the
liquidation preference of the Preferred Stock Consideration shall be in
accordance with the terms of the Certificate of Designation. In
accordance with the terms of the Certificate of Designation, if the Net
Assets shown on the Final Net Asset Reconciliation (after resolution of
all Reconciliation Disagreements) is in excess of the Net Assets shown on
the Projected Net Asset Reconciliation, then the liquidation preference
and stated value of the Preferred Stock Consideration delivered at
Closing shall be increased, dollar for dollar, to the extent of such
excess up to $10,000,000 and any remainder of such excess shall be paid,
dollar for dollar, in cash as soon as practicable after the determination
of such excess.

Allocation shall be made in accordance with Section 1060 of the Internal
Revenue Code (the "Code") and applicable Treasury regulations. Each of Harris
and Concurrent shall (i) be bound by the Allocation for purposes of
determining any Taxes (as defined in Section 4.10), (ii) prepare and file, and
cause its affiliates to prepare and file, its Tax Returns (as defined in

Harris represents and warrants to Concurrent as follows:

Section 4.1 Organization Etc.

(a) Harris and each of its Subsidiaries (as defined below) is a
corporation or other legal entity duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or
organization and has all requisite corporate power and authority to own, lease
and operate the assets owned and leased by it and to carry on its business as
now being conducted, except where the failure to be so organized, existing or
in good standing or to have such power and authority would not, individually
or in the aggregate, have a Material Adverse Effect (as defined herein) on
either Harris and its Subsidiaries taken as a whole or the Business. As used
in this Agreement, the term "Material Adverse Effect" with respect to an
entity (or group of entities taken as a whole) means such event, change or
effect which is materially adverse to the business, properties, assets,
liabilities, results of operations or financial condition of such entity (or
group of entities taken as a whole). Harris and each of its Subsidiaries is
duly qualified or licensed to do business and in good standing in each
jurisdiction in which the property owned, leased or operated by it or the
nature of the business conducted by it makes such qualification or licensing
necessary, except where the failure to be so duly qualified or licensed and in
good standing would not, individually or in the aggregate, have a Material
Adverse Effect on either Harris and its Subsidiaries taken as a whole or the
Business. For purposes of this Agreement, the term "Subsidiary" when used with
respect to any party, means any entity of which such party (either alone
or through or together with any other Subsidiary) owns, directly or
indirectly, 50% or more of the stock or other equity interests the holders of
which are generally entitled to vote for the election of the board of
directors or other governing body of such entity.

(b) Harris has heretofore made available to Concurrent a complete and
correct copy of the charter and by-laws or comparable organizational
documents, each as amended to date, of Harris and each of its Subsidiaries.
Such charters, by-laws and comparable organizational documents are in full
force and effect. Neither Harris nor any of its Subsidiaries is in violation
of any provision of its charter, by-laws or comparable organizational
documents, except for such violations that would not, individually or in the
aggregate, have a Material Adverse Effect on Harris or its Subsidiaries taken
as a whole.

Section 4.2 Capitalization.  As of the date of this Agreement, the
authorized capital stock of Harris consists of: (a) 20,000,000 shares of
Harris Common Stock of which, as of March 17, 1996, 1,995,389 shares were
issued and outstanding, no shares were held in treasury and (b) 5,000,000
shares of Preferred Stock, par value $0.01 per share, of which, as of the date
hereof, no shares were issued and outstanding and 20,000 shares were reserved
for issuance in accordance with the Stockholder Protection Rights Agreement
dated as of September 15, 1994, by and between Harris and Society National
Bank, as Rights Agent (the "Harris Rights Agreement"), pursuant to which
Harris has issued rights (the "Harris Rights") to purchase shares of Harris
Preferred Stock. As of December 31, 1995, not more than 325,000 shares of
Harris Common Stock and as of March 17, 1996 not more than 675,000 shares of
Harris Common Stock were reserved for issuance (i) upon exercise of
outstanding options or for grants of restricted stock pursuant to the Harris
Stock Incentive Plan (the "Harris Stock Plan") and (ii) upon exercise of
outstanding options awarded to directors and employees outside the Harris
Stock Plan. Except as permitted by Section 6.1 and Schedule 6.1, since the
date hereof, Harris has not issued any shares of Harris Common Stock, except
upon the exercise of options granted under the Harris Stock Plan which were
outstanding on the date hereof. All the outstanding shares of Harris's capital
stock are, and all shares which may be issued pursuant to the Harris Stock
Plan will be, when issued and paid for in accordance with the respective terms
thereof, duly authorized, validly issued, fully paid and nonassessable and not
subject to any preemptive rights of third parties in respect thereto. The
Purchased Harris Shares when issued and paid for in accordance with the terms
hereof will be duly authorized, validly issued, fully paid and nonassessable
and not subject to any preemptive rights of third parties in respect thereto.
Except as set forth above or on Schedule 4.2 hereto, as of the date of this
Agreement, there are no existing options, warrants, calls, subscriptions or
other rights or other agreements or commitments of any character relating to
the issued or unissued capital stock of Harris or any of its Subsidiaries
obligating Harris or any of its Subsidiaries to issue, transfer or sell or
cause to be issued, transferred or sold any shares of capital stock of, or
other equity interests in, Harris or any of its Subsidiaries or securities
convertible into or exchangeable for such shares or equity interests or
obligating Harris or any of its Subsidiaries to grant, extend or enter into
any such option, warrant, call, subscription or other right, agreement or
commitment. As of the date of this Agreement, except as set forth on Schedule
4.2 hereto, there are no outstanding contractual obligations of Harris or any
of its Subsidiaries to repurchase, redeem or otherwise acquire any shares of
capital stock of Harris or any of its Subsidiaries. Each of the outstanding
shares of capital stock of each of Harris's Subsidiaries is duly authorized,
validly issued, fully paid and nonassessable, and such shares are owned by
Harris free and clear of any lien, claim, option, charge, security interest,
limitation on voting rights and encumbrance of any kind, except as would not
have a Material Adverse Effect on either Harris and its Subsidiaries taken as
a whole or the Business.

Section 4.3 Authority.  Harris has the requisite corporate power and
authority to execute and deliver this Agreement and the Ancillary Agreements
to which it is a party and to consummate the transactions contemplated hereby

transactions contemplated hereby by the affirmative vote of the holders of a
majority of the outstanding shares of Harris Common Stock). The execution,
delivery and performance of this Agreement and the Ancillary Agreements by
Harris and the consummation by Harris of the transactions contemplated hereby

filings would not prevent or delay consummation of the transactions
contemplated by this Agreement and the Ancillary Agreements in any material
respect and would not, individually or in the aggregate, have a Material
Adverse Effect on either Harris and its Subsidiaries taken as a whole or the
Business), (iii) result in a violation or breach of, or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, amendment, cancellation or acceleration) under, or
result in the creation of any lien or other encumbrance on any property or
asset of Harris or any of its Subsidiaries pursuant to, any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, lease,

would not, individually or in the aggregate, have a Material Adverse Effect on
either Harris and its Subsidiaries taken as a whole or the Business.

(b) Except as disclosed in the Harris SEC Documents (as defined in
Section 4.5) or on Schedule 4.4(b) hereto, neither Harris nor any of its

have not had and are not likely to have a Material Adverse Effect on either
Harris and its Subsidiaries taken as a whole or the Business.

Section 4.5 SEC Reports and Financial Statements.  Harris has filed with
the Securities and Exchange Commission (the "SEC"), and has heretofore made
available to Concurrent true and complete copies of all forms, reports and
documents required to be filed by it since June 30, 1994, under the Exchange
Act or the Securities Act (as such documents have been amended since the time
of their filing, collectively, the "Harris SEC Documents"). The Harris SEC
Documents, including without limitation any financial statements or schedules
included therein, at the time filed, (a) did not contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading and (b) complied in
all material respects with the applicable requirements of the Exchange Act or
the Securities Act, as the case may be. The financial statements of Harris
included in the Harris SEC Documents complied as to form in all material
respects with applicable accounting requirements and with the published rules
and regulations of the SEC with respect thereto, have been prepared in
accordance with GAAP applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto or, in the case of the
unaudited statements, as permitted on Harris's Form 10-Q as filed with the SEC
under the Exchange Act) and fairly present (subject, in the case of the
unaudited statements, to normal, recurring audit adjustments which will not be
material in amount or effect) the consolidated financial position of Harris
and its consolidated Subsidiaries as at the dates thereof and the consolidated
results of their operations and cash flows for the periods then ended. Except
as reflected, reserved against or otherwise disclosed in the financial
statements of Harris included in the Harris SEC Documents or as disclosed on
Schedule 4.5 hereto, neither Harris nor any of its Subsidiaries has any
liabilities or obligations (absolute, accrued, fixed, contingent or otherwise)
material to Harris and its Subsidiaries taken as a whole that would be
required to be reflected on, or reserved against in, a balance sheet of Harris
or the notes thereto, prepared in accordance with generally accepted
accounting principles consistently applied.

Section 4.6 Information in Disclosure Documents.  None of the information
supplied or to be supplied by Harris in writing specifically for inclusion or
incorporation by reference in the joint proxy statement relating to the
meeting of the stockholders of Harris and Concurrent (respectively, the
"Harris Stockholder Meeting" and the "Concurrent Stockholder Meeting" and
collectively, the "Stockholder Meetings") to be held in connection with the
transactions contemplated by this Agreement (the "Proxy Statement") will, at
the time the Proxy Statement is filed with the SEC, at the time such Proxy
Statement is mailed to stockholders of Harris and Concurrent, at the times of
the Stockholder Meetings to be held in connection with the transactions
contemplated by this Agreement and at the Closing Date, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they are made, not misleading. The Proxy
Statement will, when filed with the SEC, comply as to form in all material
respects with the provisions of the Exchange Act and the rules and regulations
thereunder, except that no representation is made by Harris with respect to
statements made therein based on information supplied by Concurrent in writing
specifically for inclusion in the Proxy Statement.

Section 4.7 Litigation.  Except as disclosed in the Harris SEC Documents
or on Schedule 4.7 hereto, there is no suit, claim, action, proceeding or
investigation pending or, to the best knowledge of Harris, threatened, against
Harris or any of its Subsidiaries before any Governmental Entity which,
individually or in the aggregate, is reasonably likely to have a Material
Adverse Effect on either Harris or any of its Subsidiaries taken as a whole or
the Business or a Material Adverse Effect on the ability of Harris to
consummate the transactions contemplated by this Agreement. Except as
disclosed in the Harris SEC Documents or on Schedule 4.7 hereto, neither
Harris nor any of its Subsidiaries is subject to any outstanding order, writ,
injunction or decree which, insofar as can be reasonably foreseen,
individually or in the aggregate, would in the future have a Material Adverse
Effect on either Harris or any of its Subsidiaries taken as a whole or the
Business or a Material Adverse Effect on the ability of Harris to consummate
the transactions contemplated by this Agreement. Harris has, in accordance
with GAAP, made adequate provision in its financial statements for the payment
of losses arising out of suits, claims, actions, proceedings or investigations
disclosed in the Harris SEC Document or on Schedule 4.7 and such provision has
continued to be adequate.

its Subsidiaries taken as a whole or the Business, (b) any declaration,
setting aside or payment of any dividend or other distribution with respect to
its capital stock or (c) any material change in its accounting principles,
practices or methods.

deficiencies and assessments asserted as a result of such examinations or
other audits by federal, state, local or foreign taxing authorities have
been paid, fully settled or adequately provided for in the Harris SEC
Documents in accordance with GAAP, and no issue or claim has been
asserted for Taxes by any taxing authority for any prior period, the
adverse determination of which would result in a deficiency which would

taken as a whole or the Business, other than those heretofore paid or
provided for. Except as disclosed on Schedule 4.10(b)(ii) hereto, no
issue has been raised during the past five years by any federal, state,
local or foreign taxing authority which, if raised with regard to any
other period not so examined, could reasonably be expected to result in a
proposed deficiency for any other period not so examined.

Agreement, the term "Tax Return" shall mean any report, return or other

Claim Harris has or may have retained or assumed either contractually or by
operation of law.

(d) As used in this Agreement, the term "Environmental Laws" means all

alleged violation, of any Environmental Law. As used in this Agreement, the

the Business as they are presently being operated by Harris and the
Transferred Subsidiaries, and, except as otherwise contemplated by the terms
hereof and the terms of the Ancillary Agreements, will enable Concurrent and
the Transferred Subsidiaries to operate the Business immediately after the
Closing as Harris and the Transferred Subsidiaries operated the Business
immediately prior to the Closing. As of the Closing Date, all of the machines,
equipment and other assets that constitute tangible personal property that are
being operated in connection with the Business are in usable condition for the
purpose for which they are intended subject to ordinary wear and tear and
routine maintenance. Harris has, and, except as otherwise contemplated by the
terms hereof (including Schedule 1.1(b) which describes the extent to which
Shared Assets are transferred to Concurrent) or the terms of the Ancillary
Agreements, at Closing Harris will deliver to Concurrent good and valid title 
to all of the tangible personal property included in the Assets subject to 
(i) any security interests, mortgages, liens, pledges, conditional sale or 
other title retention agreements, rights of first refusal, options, leases, 
adverse claims, or any other encumbrances (the "Encumbrances") relating to 
purchase money security interests entered into in the ordinary course of 
business consistent with past practice and reflected in the Audited Balance 
Sheet or the Final Net Current Asset Reconciliation; and (ii) Encumbrances

assignments thereof, subleases, subordination and/or nondisturbance agreements
and all other agreements creating, amending or modifying the leasehold estates
in the Leased Properties.

(b) With respect to the Leased Properties: (i) to the best knowledge of

structures located thereon which would be reasonably expected to substantially
impair the operation of the Business immediately preceding the Closing as

constitute legal, valid and binding obligations of Harris, in accordance with

occurrence, condition or act (other than the transaction contemplated
hereunder) which, with the giving of notice, the lapse of time or the
happening of any further event or condition, would become a material default
thereunder.

Section 4.24 Subsidiaries.

have good and valid title to, the Harris Subsidiary Shares, free and clear of
any Encumbrance, as analogous concepts are understood under applicable local
laws. Upon delivery, all of the issued and outstanding shares of each
Transferred Subsidiary will be duly authorized, validly issued, fully paid and
non-assessable and not subject to any preemptive rights of third parties in
respect thereto.

Section 4.25 Outstanding Liabilities to Related Parties.  There are no
outstanding liabilities, contingent or otherwise, relating to the Business or
that will arise out of the transactions contemplated by this Agreement (except
as set forth in this Agreement) for amounts due to shareholders, directors,
officers, employees or other parties affiliated with or related to Harris or,
to the best knowledge of Harris after reasonable inquiry, the Transferred
Subsidiaries other than amounts due to directors, officers and employees in
the ordinary course of business consistent with past practice.

Section 4.26 Product Returns; Warranties.

(a) There are no liabilities for product returns, warranty obligations
and product services other than those arising in the ordinary course of
business, consistent with Harris's historical practice relating to the
Business and in accordance with normal industry standards. Harris has no
knowledge of any threatened claims for any extraordinary (i) product returns,
(ii) warranty obligations or (iii) product services, relating to the Business,
reserved or otherwise. Harris has made adequate provision for product returns
and warranty obligations in the Audited Balance Sheet in accordance with GAAP.

(b) Any liabilities for product returns and warranty obligations are
fully accrued and fully reserved against on each of the Audited Base Financial
Statements provided by Harris to Concurrent. Such reserves are adequate to pay
any amounts which may be owed by Harris of any of its Subsidiaries to any
party as a result of the incurrence of such liabilities.

(c) True and correct copies of the standard warranty provided by Harris
on sales orders and other related documents which are delivered in connection
with the Business have been made available to Concurrent. Such warranty
delivered is the only warranty applicable to the products of the Business
except for warranties provided by applicable law.

Section 4.27 Transferred Subsidiaries.  There exists no debt, liability
or other obligation of the Transferred Subsidiaries, contingent or otherwise,
except those that will be reflected on the Final Net Current Asset
Reconciliation.

Section 4.28 Transferred Subsidiaries Financial Statement.  (a) Harris
has previously delivered to Concurrent true and complete copies of the
statutory balance sheets as of September 30, 1995 and 1994 and the statements
of operations for the fiscal periods ended September 30, 1995 and 1994 of each
Transferred Subsidiary, together with the notes to such financial statements
(where available) (the "Transferred Subsidiaries Financial Statements").

(b) Each Transferred Subsidiary Financial Statement presents fairly in
all material respects, the financial condition of such Transferred Subsidiary
as at its respective date or during the respective period; and each of such
Transferred Subsidiary Financial Statements has been prepared in accordance
with GAAP consistently applied during the periods involved, except as
otherwise stated therein.

Section 4.29 Investment Purpose.  Harris will acquire the shares of
Concurrent Common Stock to be issued pursuant to this Agreement and the

to an exemption from the Securities Act and all applicable state securities
laws confirmed by an opinion of counsel satisfactory to Concurrent, the
expense for which shall be borne by Harris.

Section 4.30 Rights Agreement.  Harris shall take all necessary and
appropriate actions such that (i) Concurrent will not become an "Acquiring
Person", (ii) no "Stock Acquisition Date", "Separation Time", "Flip-over
Transaction" or "Flip-in Date" (as such terms are defined in the Harris Rights
Agreement) will occur and (iii) the stockholders of Harris will not be
entitled to receive any right or benefit under the Harris Rights Agreement as
a result of the approval, execution or delivery of this Agreement by Harris or

                        ARTICLE V

       REPRESENTATIONS AND WARRANTIES OF CONCURRENT

Concurrent represents and warrants to Harris as follows:

Section 5.1 Organization.

(a) Concurrent and each of its Subsidiaries is a corporation or other
legal entity duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation or organization and has all
requisite corporate power and authority to own, lease and operate its
properties and to carry on its business as now being conducted, except where
the failure to be so organized, existing or in good standing or to have such
power and authority would not, individually or in the aggregate, have a
Material Adverse Effect on Concurrent and its Subsidiaries taken as a whole.
Concurrent and each of its Subsidiaries is duly qualified or licensed to do
business and in good standing in each jurisdiction in which the property
owned, leased or operated by it or the nature of the business conducted by it
makes such qualification or licensing necessary, except where the failure to
be so duly qualified or licensed and in good standing would not, individually
or in the aggregate, have a Material Adverse Effect on Concurrent and its
Subsidiaries taken as a whole.

(b) Concurrent has heretofore made available to Harris a complete and
correct copy of the charter and by-laws or comparable organizational
documents, each as amended to date, of Concurrent and each of its
Subsidiaries. Such charters, by-laws and comparable organizational documents
are in full force and effect. Neither Concurrent nor any of its Subsidiaries
is in violation of any provision of its charter, by-laws or comparable
organizational documents, except for such violations that would not,
individually or in the aggregate, have a Material Adverse Effect on Concurrent
and its Subsidiaries taken as a whole.

Section 5.2 Capitalization.  As of the date of this Agreement, the
authorized capital stock of Concurrent consists of: (a) 100,000,000 shares of
Concurrent Common Stock of which, as of March 20, 1996 30,569,159 shares were
issued and outstanding and 840 shares were held in treasury; and (b)
25,000,000 shares of Series Preferred Stock, par value $.01 per share, of
which, as of the date of this Agreement, no shares are issued and outstanding

Preferred Stock, and are reserved for issuance in accordance with the Rights

Boston, as Rights Agent (the "Concurrent Rights Agreement"). As of December
31, 1995, 3,042,495 shares of Concurrent Common Stock and as of the date
hereof not more than 3,042,495 shares of Concurrent Common Stock were reserved
for issuance upon exercise of outstanding options (the "Concurrent Options")
pursuant to Concurrent's Stock Option Plan (the "Concurrent Stock Plan").
Since the date hereof, Concurrent has not issued any shares of Concurrent
Common Stock, except upon the exercise of options granted under Concurrent
Stock Plan which were outstanding on the date hereof. All the outstanding
shares of Concurrent's capital stock are, and all shares of Concurrent Common
Stock and Concurrent Preferred Stock which are to be issued to Harris pursuant
to the transactions contemplated by this Agreement will be, when issued and
paid for in accordance with the respective terms thereof, duly authorized,
validly issued, fully paid and nonassessable and not subject to any preemptive
rights of third parties in respect thereto. The Debentures issuable in
exchange for the Preferred Stock Consideration have been duly authorized.
Except as set forth above or on Schedule 5.2 hereto, as of the date of this
Agreement, there are no existing options, warrants, calls, subscriptions or
other rights or other agreements or commitments of any character relating to
the issued or unissued capital stock of Concurrent or any of its Subsidiaries
obligating Concurrent or any of its Subsidiaries to issue, transfer or sell or
cause to be issued, transferred or sold any shares of capital stock of, or
other equity interests in, Concurrent or of any of its Subsidiaries or
securities convertible into or exchangeable for such shares or equity
interests or obligating Concurrent or any of its Subsidiaries to grant, extend
or enter into any such option, warrant, call, subscription or other right,
agreement or commitment. As of the date of this Agreement, except as set forth
on Schedule 5.2 hereto, there are no outstanding contractual obligations of
Concurrent or any of its Subsidiaries to repurchase, redeem or otherwise
acquire any shares of capital stock of Concurrent or any of its Subsidiaries.
Each of the outstanding shares of capital stock of each of Concurrent's
Subsidiaries is duly authorized, validly issued, fully paid and nonassessable,
and such shares are owned by Concurrent or by a Subsidiary of Concurrent free
and clear of any lien, claim, option, charge, security interest, limitation on 
voting rights and encumbrance of any kind, except as would not have a Material
Adverse Effect on Concurrent and its Subsidiaries taken as whole.

Section 5.3 Authority.  Concurrent has the requisite corporate power and
authority to execute and deliver this Agreement and the Ancillary Agreements
and to consummate the transactions contemplated hereby and thereby (other than
(a) with respect to the issuance of shares of Concurrent Common Stock pursuant
to the transactions contemplated by this Agreement and the Ancillary
Agreements, the approval of the holders of Concurrent Common Stock required
for such issuance by the affirmative vote of a majority of the total votes
cast and (b) with respect to the Concurrent Stock Plan Amendment (as defined
in Section 5.12) the affirmative vote of a majority of the voting shares of
Concurrent Common Stock in a separate vote). The execution, delivery and
performance of this Agreement and the Ancillary Agreements by Concurrent and
the consummation by Concurrent of the other transactions contemplated hereby
and thereby have been duly authorized by all necessary corporate action on the
part of Concurrent and no other corporate proceedings on the part of
Concurrent are necessary to authorize this Agreement and the Ancillary
Agreements or to consummate the transactions contemplated hereby and thereby
(other than, with respect to the issuance of shares of Concurrent Common Stock
and Preferred Consideration pursuant to the transactions contemplated by this
Agreement (including Common Stock issuable upon the conversion of the
Preferred Stock Consideration or any debentures for which such consideration
is exchangeable pursuant to its terms) and the Ancillary Agreements, the
approval of the holders of Concurrent Common Stock required for such issuance
by the affirmative vote of a majority of the total votes cast). This Agreement
and the Ancillary Agreements have been duly executed and delivered by
Concurrent and, assuming this Agreement and the Ancillary Agreements
constitute valid and binding obligations of Harris, constitute valid and
binding obligations of Concurrent, enforceable against Concurrent in
accordance with their respective terms.

Section 5.4 Consents and Approvals; No Violations.

(a) Except as set forth on Schedule 5.4(a) hereto, and except for
filings, permits, authorizations, notices, consents and approvals as may be
required under, and other applicable requirements of, the Exchange Act, the
Securities Act, the HSR Act, the FBCA, certain state takeover statutes or
state securities or blue sky laws, neither the execution, delivery or
performance of this Agreement and the Ancillary Agreements by Concurrent nor
the consummation by Concurrent of the transactions contemplated hereby and
thereby and compliance by Concurrent with any of the provisions hereof and
thereof will (i) conflict with or result in any breach of any provision of the
respective certificates of incorporation or by-laws or comparable
organizational documents of Concurrent or any Subsidiary of Concurrent, (ii)
require any filing with, or permit, authorization, consent or approval of, any
Governmental Entity (except where the failure to obtain such permits,
authorizations, consents or approvals or to make such filings would not
prevent or delay consummation of the transactions contemplated by this
Agreement and the Ancillary Agreements in any material respect and would not,
individually or in the aggregate, have a Material Adverse Effect on Concurrent
and its Subsidiaries taken as a whole), (iii) result in a violation or breach
of, or constitute (with or without due notice or lapse of time or both) a
default (or give rise to any right of termination, amendment, cancellation or
acceleration) under, or result in the creation of any lien or other
encumbrance on any property or asset of Concurrent or any of its Subsidiaries
pursuant to any of the terms, conditions or provisions of any note, bond,
mortgage, indenture, license, lease, contract, agreement or other instrument
or obligation to which Concurrent or any of its Subsidiaries is a party or by
which any of them or any of their properties or assets may be bound or (iv)
violate any order, writ, injunction, decree, statute, rule or regulation
applicable to Concurrent or any of its Subsidiaries or by which any property
or asset of Concurrent or any of its Subsidiaries is bound or affected,
except, in the case of clauses (iii) and (iv), for violations, breaches,
defaults or other occurrences which would not prevent or delay consummation of
this Agreement and the Ancillary Agreements or the transactions contemplated
hereby or thereby in any material respect and would not, individually or in
the aggregate, have a Material Adverse Effect on Concurrent and its
Subsidiaries taken as a whole.

(b) Except as disclosed in the Concurrent SEC Documents (as defined in
Section 5.5) or on Schedule 5.4(b) hereto, neither Concurrent nor any of its
Subsidiaries is in conflict with, or in default or violation of, (i) any
order, writ, injunction, decree, statute, rule or regulation of any
Governmental Entity applicable to Concurrent or any of its Subsidiaries or by
which any of them or any of their properties or assets may be bound
or (ii) any note, bond, mortgage, indenture, lease, license, contract,
agreement or other instrument or obligation to which Concurrent or any of its
Subsidiaries is a party or by which any of them or any of their properties or
assets may be bound or affected, except for any such conflicts, defaults or
violations which have not had and are not likely to have a Material Adverse
Effect on Concurrent and its Subsidiaries taken as a whole.

Section 5.5 SEC Reports and Financial Statements.  Concurrent has filed
with the SEC, and has heretofore made available to Harris true and complete
copies of all forms, reports and other documents required to be filed by it
since June 30, 1995 under the Exchange Act or the Securities Act (as such
documents have been amended since the time of their filing, collectively, the
"Concurrent SEC Documents"). The Concurrent SEC Documents, including without
limitation any financial statements or schedules included therein, at the time
filed, (a) did not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they
were made, not misleading and (b) complied in all material respects with the
applicable requirements of the Exchange Act or the Securities Act, as the case
may be. The financial statements of Concurrent included in the Concurrent SEC
Documents complied as to form in all material respects with applicable
accounting requirements and with the published rules and regulations of the
SEC with respect thereto, have been prepared in accordance with GAAP applied
on a consistent basis during the periods involved (except as may be indicated
in the notes thereto or, in the case of the unaudited statements, as permitted
on Concurrent's Form 10-Q as filed with the SEC under the Exchange Act) and
fairly present (subject, in the case of the unaudited statements, to normal,
recurring audit adjustments which will not be material in amount or effect)
the consolidated financial position of Concurrent and its consolidated
Subsidiaries as at the dates thereof and the consolidated results of their
operations and cash flows for the periods then ended. Except as reflected,
reserved against or otherwise disclosed in the financial statements of
Concurrent included in the Concurrent SEC Documents or as disclosed on
Schedule 5.5 hereto, neither Concurrent nor any of its Subsidiaries has any
liabilities or obligations (absolute, accrued, fixed, contingent or otherwise)
material to Concurrent and its Subsidiaries taken as a whole that would be
required to be reflected on, or reserved against in, a balance sheet of
Concurrent or the notes thereto, prepared in accordance with generally
accepted accounting principles consistently applied.

Section 5.6 Information in Disclosure Documents.  None of the information
supplied or to be supplied by Concurrent in writing specifically for inclusion
or incorporation by reference in the Proxy Statement will, at the time the
Proxy Statement is filed with the SEC, at the time such Proxy Statement is
mailed to stockholders of Concurrent and Harris, at the times of the meetings
of stockholders of Concurrent and Harris to be held in connection with the
transactions contemplated by this Agreement and at the Closing Date, contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading. The Proxy Statement will, when filed with the SEC, comply as to
form in all material respects with the provisions of the Exchange Act and the
rules and regulations thereunder, except that no representation is made by
Concurrent with respect to statements made therein based on information
supplied by Harris in writing specifically for inclusion in the Proxy
Statement.

Section 5.7 Litigation.  Except as disclosed in the Concurrent SEC
Documents or on Schedule 5.7 hereto, there is no suit, claim, action,
proceeding or investigation pending or, to the best knowledge of Concurrent,
threatened, against Concurrent or any of its Subsidiaries before any
Governmental Entity which, individually or in the aggregate, is reasonably
likely to have a Material Adverse Effect on Concurrent and its Subsidiaries
taken as a whole or a Material Adverse Effect on the ability of Concurrent to
consummate the transactions contemplated by this Agreement. Except as
disclosed in the Concurrent SEC Documents or on Schedule 5.7 hereto, neither
Concurrent nor any of its Subsidiaries is subject to any outstanding order,
writ, injunction or decree which, insofar as can be reasonably foreseen,
individually or in the aggregate, would in the future have a Material Adverse
Effect on Concurrent and its Subsidiaries taken as a whole or a Material
Adverse Effect on the ability of Concurrent to consummate the transactions
contemplated by this Agreement. Concurrent has, in accordance with GAAP, made
adequate provision in its financial statements for the payment of losses 
arising out of suits, claims, actions, proceedings or investigations disclosed 
in the Concurrent SEC Documents or on Schedule 5.7 and such provision has 
continued to be adequate.

Section 5.8 Absence of Certain Changes.  Except as disclosed in the
Concurrent SEC Documents or on Schedule 5.8 hereto, since June 30, 1995,
Concurrent has conducted its business in the ordinary course of such business
and there has not been any (a) material adverse change in Concurrent and its
Subsidiaries taken as a whole, (b) any declaration, setting aside or payment
of any dividend or other distribution with respect to its capital stock or (c)
any material change in its accounting principles, practices or methods.

Section 5.9 Opinion of Financial Advisor.  Concurrent has received the
opinion of Berenson Minella & Company, its financial advisor, to the effect
that, as of the date of this Agreement, the purchase of the Assets and the
Purchased Harris Shares for the Common Stock Consideration and the Preferred
Stock Consideration and the Assumed Liabilities, taken as a whole, are fair to
the stockholders of Concurrent from a financial point of view.

Section 5.10 Rights Agreement.  Concurrent shall take all necessary and
appropriate actions such that (a) Harris will not become an "Acquiring
Person", (b) no "Stock Acquisition Date", "Distribution Date" or "Triggering
Event" (as such terms are defined in Concurrent Rights Agreement) will occur
and (c) Concurrent Stockholders will not become entitled to receive any right
or benefit under the Concurrent Rights Agreement as a result of the approval,
execution or delivery of this Agreement by Concurrent, or the consummation of
the transactions contemplated hereby.

Section 5.11 Tax Matters.

(a) Concurrent and each of its Subsidiaries has duly filed, or as of the
Closing Date will have filed, all Tax Returns required to be filed by it or
its Subsidiaries on or before the Closing Date, and such Tax Returns are or
will be true, correct and complete in all material respects. Concurrent and
its Subsidiaries have duly paid, caused to be paid or made adequate provision
in the Concurrent SEC Documents in accordance with GAAP for the payment of all
Taxes required to be paid in respect of all periods covered by such Tax
Returns. Concurrent has made adequate provision in accordance with GAAP for
payment of all Taxes anticipated to be payable in respect of all taxable
periods or portions thereof ending on or before the Closing Date since the
periods covered by such Tax Returns.

(b) (i) The reserves for Taxes (except for deferred Taxes) reflected
in the Concurrent SEC Documents are sufficient for the payment of all
unpaid Taxes (whether or not currently disputed) accrued through the date
thereof. Since June 30, 1995, neither Concurrent nor its Subsidiaries
incurred any material liability for Taxes other than in the ordinary
course of business consistent with past practice. Concurrent and its
Subsidiaries are registered to do business in the states and localities
set forth on Schedule 5.11(b)(i) hereto, and Concurrent or its
Subsidiaries file all required Tax Returns in such states and localities.
Except as set forth on Schedule 5.11(b)(i) hereto, there are no liens for
Taxes upon the assets of Concurrent or its Subsidiaries except for
statutory liens for current Taxes not yet due.

(ii) The Tax Returns required to be filed by Concurrent have been
examined by the IRS or other appropriate taxing authority for all taxable
years as set forth on Schedule 5.11(b)(ii) hereto. Except as set forth on
Schedule 5.11(b)(ii) hereto, all deficiencies and assessments asserted as
a result of such examinations or other audits by federal, state, local or
foreign taxing authorities have been paid, fully settled or adequately
provided for in the Concurrent SEC Documents in accordance with GAAP, and
no issue or claim has been asserted for Taxes by any taxing authority for
any prior period, the adverse determination of which would result in a
deficiency which would have a Material Adverse Effect on Concurrent and
its Subsidiaries taken as a whole, other than those heretofore paid or
provided for. Except as disclosed on Schedule 5.11(b)(ii) hereto, no
issue has been raised during the past five years by any federal, state,
local or foreign taxing authority which, if raised with regard to any
other period not so examined, could reasonably be expected to result in a
proposed deficiency for any other period not so examined.

(c) (i) Except as set forth on Schedule 5.11(c) hereto, there are no
outstanding agreements or waivers extending the statutory period of
limitation applicable to any Tax Return of Concurrent or its
Subsidiaries. Except as set forth on Schedule 5.11(c) hereto, neither
Concurrent nor any of its Subsidiaries (x) has been a member of a group
filing consolidated returns for federal income tax purposes, or (y) is a
party to a tax sharing or tax indemnity agreement or any other agreement
of a similar nature that remains in effect. Except as set forth on
Schedule 5.11(c) hereto, no power of attorney has been executed by, or on
behalf of Concurrent or its Subsidiaries with respect to any matter
relating to Taxes which is currently in force.

(ii) Neither Concurrent nor any of its Subsidiaries have filed a
consent pursuant to Section 341(f) of the Code or agreed to have Section
341(f)(2) of the Code apply to any disposition of a subsection (f) asset
(as such term is defined in Section 341(f)(2) of the Code) owned by
Concurrent or any of its Subsidiaries.

Section 5.12 Vote Required.  The only votes of the holders of any class
or series of Concurrent's capital stock necessary to approve the transactions
contemplated hereby are the affirmative vote of a majority of (i) the total
votes cast by the holders of Concurrent Common Stock with respect to the
issuance of Concurrent Common Stock pursuant to the transactions contemplated
by this Agreement and (ii) the total votes cast by the holders of Concurrent
Common Stock, in a separate vote, with respect to an amendment to the
Concurrent Stock Plan (the "Concurrent Stock Plan Amendment") in the form set
forth on Exhibit E hereto.

Section 5.13 Employee Benefit Plans; ERISA.

(a) Schedule 5.13(a) contains a true and complete list of each bonus,
deferred compensation, incentive compensation, stock purchase, stock option,
severance or termination pay, hospitalization or other medical, life or other
insurance, supplemental unemployment benefits, profit-sharing, pension, or
retirement plan, program, agreement or arrangement, and each other employee
benefit plan, program, agreement or arrangement, sponsored, maintained or
contributed to or required to be contributed to by Concurrent or by any trade
or business, whether or not incorporated (a "Concurrent ERISA Affiliate"),
that together with Concurrent would be deemed a "single employer" within the
meaning of section 4001 of ERISA, for the benefit of any employee or
terminated employee of Concurrent or any Concurrent ERISA Affiliate (the
"Concurrent Plans"). Schedule 5.13(a) identifies each of the Concurrent Plans
that is an "employee benefit plan," as that term is defined in section 3(3) of
ERISA (the "Concurrent ERISA Plans").

(b) With respect to each Concurrent Plan, Concurrent has heretofore
delivered to Harris true and complete copies of each of the following
documents:

(i) a copy thereof;

jeopardize the attorney-client privilege of the institution in possession or
control of such information or contravene any law, rule, regulation, order,
judgment, decree, fiduciary duty or binding agreement entered into prior to
the date of this Agreement. Unless otherwise required by law, the parties will
hold any such information which is nonpublic in confidence in accordance with
the terms of Section 1 of that certain letter agreement, dated September 28,
1995, between Concurrent and Harris (the "Confidentiality Agreement"), and in

holders Meetings on the same day and as soon as practicable after the date 
hereof; provided, however, that nothing contained in this Section 6.7 shall 
require the Board of Directors of Harris or Concurrent to take any action or 
refrain from taking any action in violation of its fiduciary duties.  In 
addition, Concurrent may seek approval from its shareholders at the Concurrent 
Stockholders Meeting, if required by applicable law or the rules and 
regulations of NASDAQ; for a reverse stock split at or following the Closing 
Date; provided, however, that the transactions contemplated by this Agreement 
shall not be conditioned on approval of any such reverse stock split proposal.

Section 6.8 No Solicitation.

(a) Except as provided in Section 6.8(b), Schedule 6.1 or otherwise
agreed to by the parties hereto, until the termination of this Agreement
pursuant to Article IX, Harris and Concurrent will not, nor will either of
them permit its officers, directors, affiliates, representatives or agents,
directly or indirectly, to do any of the following:

(i) discuss, negotiate, undertake, authorize, recommend, propose or
enter into, either as the proposed surviving, merged, acquiring or
acquired corporation, any transaction (other than the transactions
contemplated by this Agreement and the Ancillary Agreements) involving
any disposition or other change of ownership of a substantial portion of
(x) Harris's or Concurrent's or their respective Subsidiaries' capital
stock or assets or (y) the Business (an "Acquisition Transaction");

(ii) facilitate, encourage, solicit or initiate or in any way engage
in any discussion, negotiation or submission of a proposal or offer in
respect of an Acquisition Transaction;

(iii) furnish or cause to be furnished to any corporation,
partnership, individual or other entity or group (other than the other
party and its representatives) (a "Person") any information concerning
the business, operations, properties or assets of Harris or Concurrent in
connection with an Acquisition Transaction; or

(iv) otherwise cooperate in any way with, or assist or participate
in, facilitate or encourage, any effort or attempt by any other Person to
do or seek any of the foregoing.

Harris and Concurrent will immediately cease and cause to be terminated
any existing activities, discussions or negotiations with any Person conducted
heretofore with regard to an Acquisition Transaction and will take the
necessary steps to inform such Persons of the obligations undertaken in this
Section 6.8. Each party will inform the other party by telephone within 24
hours of its receipt of any proposal or bid (including the terms thereof and
the Person making such proposal or bid) in respect of any Acquisition
Transaction.

(b) Notwithstanding anything else contained in this Section 6.8, either
party may engage in discussions or negotiations with, and may furnish
information to, a third party who, or representatives of a third party who,
makes a written, bona fide proposal with respect to an Acquisition Transaction
that is reasonably capable of being consummated and, as determined in good
faith by its Board of Directors after consultation with its financial
advisors, is more favorable to such party's stockholders than the transactions
contemplated hereby, provided that the Board of Directors of such party shall
have determined in good faith on the basis of the advice of outside counsel
that failure to take such action creates a substantial risk that the Board of
Directors would fail to comply with its fiduciary duties under applicable law.
Nothing in this Section 6.8 shall (i) permit any party to terminate this
Agreement (except as specifically provided in Article IX hereof), (ii) permit
any party to enter into any agreement with respect to an Acquisition
Transaction during the term of this Agreement (it being agreed that during the
term of this Agreement, no party shall enter into any agreement with any
person that provides for, or in any way facilitates, an Acquisition
Transaction (other than a confidentiality agreement in customary form)), or
(iii) affect any other obligation of any party under this Agreement.

Section 6.9 Brokers or Finders.  Each of Concurrent and Harris agree to

or affiliate.

required to do so by order of a court of competent jurisdiction.

Section 6.11 Publicity.  The initial press release relating to this
Agreement shall be a joint press release and thereafter Harris and Concurrent

of stock exchanges and other similar regulatory bodies), consult with each
other, and use reasonable efforts to agree upon the text of any press release,
before issuing any such press release or otherwise making public statements
with respect to the transactions contemplated hereby and in making any filings
with any federal or state governmental or regulatory agency or with any
national securities exchange with respect thereto. With respect to all other
press releases during the term of this Agreement, the parties hereto shall use
reasonable efforts to consult with each other prior to issuing such press
releases.

notice to Concurrent, and Concurrent shall give prompt notice to Harris, of

non-occurrence, of which would be likely to cause (i) any representation or
warranty contained in this Agreement to be untrue or inaccurate or (ii) any
covenant, condition or agreement contained in this Agreement not to be

case may be, to comply with or satisfy any covenant, condition or agreement to

such party receives such Supplemental Disclosure.

(c) The Supplemental Disclosure will not be deemed to have cured any
breach of any representation or warranty made in this Agreement as of the date

obligations set forth in Article X hereof.

Section 6.19 Further Assurances; Subsequent Transfers.

(a) The parties hereto shall execute and deliver such further instruments
of conveyance, transfer, assignment and other similar documents and shall take
such other actions as each of them may reasonably request of the other in
order to effectuate the purposes of this Agreement and to carry out the terms
hereof. Without limiting the generality of the foregoing, at any time and from
time to time after the Closing Date, (i) at the request of Concurrent, Harris
shall execute and deliver to Concurrent such other instruments of transfer,
conveyance, assignment and confirmation and take such action as Concurrent may
reasonably deem necessary or desirable in order to more effectively transfer,
convey and assign to Concurrent and to confirm Concurrent's title to all of
the Assets, to put Concurrent in actual possession and operating control
thereof and to permit Concurrent to exercise all rights with respect thereto
(including, without limitation, rights under contracts and other arrangements
as to which the consent of any third party to the transfer thereof shall not
have previously been obtained), (ii) at the request of Harris, Concurrent
shall execute and deliver to Harris all instruments, undertakings or other
documents and take such other action as Harris may reasonably deem necessary
or desirable in order to have Concurrent fully assume and be liable for the
Assumed Liabilities and shall deliver to Harris any of the Excluded Assets
inadvertently left in the control or possession of Concurrent, and (iii) at
the request of Concurrent, Harris shall execute and deliver to the appropriate
Transferred Subsidiaries all instruments, undertakings or other documents and
take such other action as Concurrent may reasonably deem necessary or
desirable in order to have Harris fully assume the Excluded Liabilities as
they relate to the Transferred Subsidiaries. Notwithstanding the foregoing,
the parties shall not be obligated, in connection with the foregoing, to
expend monies other than reasonable out-of-pocket expenses and attorneys'
fees.

(b) Harris shall use its Best Efforts to obtain any consent, approval or
amendment required to novate and/or assign all agreements, Leases, licenses
and other rights of any nature whatsoever relating to the transfer of the
Assets to Concurrent. In the event and to the extent that Harris is unable to
obtain any such required consent, approval, amendment or modification (except
with respect to any Lease, agreement or license set forth in Schedule 8.2(d)
hereof) (i) Harris shall continue to be bound by such agreements, leases,
licenses or other matters, (ii) unless not permitted by law, Concurrent shall
pay, perform and discharge fully all the obligations of Harris thereunder and
indemnify Harris for all liabilities arising out of such performance by
Concurrent (but only to the extent that (x) such liabilities are Assumed
Liabilities and (y) in the case of a Lease, upon such payment or performance,
Concurrent shall be entitled to use and occupancy of the premises covered by
such lease) and (z) so long as Concurrent has paid, performed and discharged
the obligations of Harris, Harris shall, without further consideration
therefor, pay and remit to Concurrent promptly all monies, rights and other
considerations received in respect of such performance. Harris shall exercise
or exploit its rights and options under all such agreements, leases, licenses
and other rights and commitments (other than in connection with the Leases
referred to in Schedule 8.2(d) hereof) referred to in this Section 6.19(b)
only as reasonably directed by Concurrent. If and when any such consent shall
be obtained or such agreement, lease, license or other right (other than in
connection with the Leases referred to in Schedule 8.2(d) hereof) shall
otherwise become assignable or able to be novated, Harris shall promptly
assign and novate all its rights and obligations thereunder to Concurrent
without payment of further consideration and Concurrent shall, without the
payment of any further consideration therefor, assume such rights and
obligations.

Section 6.20 Risk of Loss.

(a) Leasehold Properties:

(i) In the event that during the period between the date hereof and
    the Closing, all or any portion of the Leased Property included
    in the Assets (a "Property") is damaged by fire or other
    casualty, Harris shall promptly give notice thereof to
    Concurrent. If such damage materially affects the ability of
    Concurrent at Closing to conduct the Business as contemplated
    herein, Concurrent shall have the right to terminate this
    Agreement. In the event of such termination, all parties shall
    be released from all liability hereunder.

(ii) If as a result of such casualty, the Property is partially
     damaged or rendered partially unusable for the purposes for
     which such Property is used by Harris on the date hereof, but
     such damage does not materially affect Concurrent's ability to
     conduct the Business at Closing as conducted on the date
     hereof, then Harris shall convey such Property to Concurrent at
     Closing in its damaged condition upon and subject to all of the
     other terms and conditions of this Agreement, and Harris shall
     assign to Concurrent all of Harris's right, title and interest
     in and to any claims Harris may have under its insurance
     policies, and/or any causes of action with respect to such
     damage or destruction, and shall assign to Concurrent all
     insurance proceeds awarded to Harris under such policies with
     respect to the damage to the Property. Notwithstanding the
     foregoing, in the event that the damaged Property was not
     covered by insurance or the insurance proceeds received by
     Concurrent pursuant to the preceding sentence are insufficient
     to restore the Property to its condition prior to such casualty
     ("Concurrent Casualty Deficiency"), then (x) if a Concurrent
     Casualty Deficiency is discovered prior to the determination of
     the Preferred Stock Consideration pursuant to Section 2.3, the
     liquidation value and stated value of the Preferred Stock
     Consideration shall be reduced by an amount equal to the
     additional cost (the "Concurrent Additional Cost"), as
     estimated by an engineer or architect, selected by Harris and
     reasonably acceptable to Concurrent, required to repair such
     damage and restore the Property to its condition immediately
     prior to the casualty or (y) if a Concurrent Casualty
     Deficiency is discovered subsequent to the determination of the
     Preferred Stock Consideration pursuant to Section 2.3, Harris
     shall, within five days of the determination of the Concurrent
     Additional Cost, pay such cost to Concurrent in cash or other
     immediately available funds.

(iii) In the event such Property is totally destroyed or rendered
      wholly unusable for the purposes for which it was used by
      Harris prior to the casualty but such damage does not
      materially affect Concurrent's ability to conduct the Business
      at Closing as conducted on the date hereof, then such Property
      shall be excluded from Assets, and the parties shall proceed
      to the Closing with respect to the remaining Assets upon and
      subject to all of the other terms and conditions of this
      Agreement, except that the liquidation preference Preferred
      Stock Consideration hereunder shall be reduced in an amount
      equal to the Fair Market Value (as defined in Section 6.20(b))
      of such Property prior to such casualty.

(b) Fair Market Value:

Fair Market Value of the Leased Properties shall mean the fair market
value of the interest on such Property contemplated to be transferred by this
Agreement, as if such Property were available in the then leasing market, for
comparable property, as determined by an independent real estate appraiser
selected by Harris (in the case of the Leased Properties) (the "First
Appraiser"), which appraisal shall be made within thirty (30) days after the
occurrence of the casualty. If Concurrent (in the event of a total destruction
of the Leased Properties), disputes the determination of the First Appraiser,
which dispute must be raised within twenty (20) days after receipt by
Concurrent of the First Appraiser's determination, Concurrent shall appoint
its own independent real estate appraiser (the "Second Appraiser"). If within
thirty (30) days after Concurrent disputes the determination of the First
Appraiser, the First Appraiser and Second Appraiser shall mutually agree upon
the determination of the Fair Market Value of the property in question, their
determination shall be final and binding upon the parties. If the First
Appraiser and Second Appraiser are unable to reach a mutual determination
within said thirty (30) day period, both such Appraisers shall jointly
select a third real estate appraiser (the "Third Appraiser"), whose fee shall
be borne equally by Harris and Concurrent, and who shall, within thirty (30)
days of his selection, choose either the First or Second Appraiser's
determination; such choice by the Third Appraiser shall be conclusive and
binding upon the parties hereto.

Section 6.21 Compliance with Applicable Bulk Sales Laws.  Without
admitting the applicability of the bulk transfer laws of any jurisdiction,
Harris and Concurrent have agreed to waive the compliance with the
requirements of any applicable laws relating to bulk sales. Harris shall
defend, indemnify and hold Concurrent harmless from and against any Losses
incurred as a result of Harris's noncompliance with any applicable bulk
transfer laws.

Section 6.22 Audited Financial Statements; Statutory Financial
Statements.  Prior to the Closing, Harris shall have delivered to Concurrent
the Audited Balance Sheet and the statutory financial statements of the
Transferred Subsidiaries for the periods ended September 30, 1995 and
September 30, 1994.

Section 6.23 Tax Matters.  For purposes of Section 1.3, Taxes of Harris
accruing prior to Closing shall mean any Taxes of the Business attributable to
any Tax period (or portion thereof) of Harris, or any of its Subsidiaries
ending on or before the close of business on the Closing Date, and, in the
case of any Taxes that are imposed on a periodic basis or are payable for a
taxable period that includes (but does not end on) the Closing Date, the
portion of such Taxes related to the portion of such taxable period ending on
the Closing Date shall (i) in the case of any Taxes other than Taxes based
upon or related to income, be deemed to be determined on a per diem basis, and
(ii) in the case of any Taxes based upon or related to income, be deemed equal
to the amount which would be payable if the relevant taxable period ended on
the Closing Date. Any credits relating to a taxable period that begins before
and ends after the Closing Date shall be taken into account as though the
relevant taxable period ended on the Closing Date. All determinations
necessary to give effect to the foregoing allocations shall be made in a
manner consistent with the prior practice of Harris, the Transferred
Subsidiaries and their subsidiaries.

(a) Without the prior written consent of Concurrent, if a Material
Adverse Effect on the liability for Taxes of the Transferred Subsidiaries will
result therefrom, none of the Transferred Subsidiaries nor their subsidiaries
shall make or change any election, change an annual accounting period, adopt
or change any accounting method, file any amended Tax return or report, enter
into any closing agreement, settle any Tax claim or assessment relating to any
of the Transferred Subsidiaries or their subsidiaries, surrender any right to
claim a refund of Taxes, or consent to any extension or waiver of the
limitations period applicable to any Tax claim or assessment relating to any
of the Transferred Subsidiaries or their subsidiaries.

(b) "Transfer Taxes" shall be borne by Harris and Concurrent as provided
in Section 6.15. Transfer Taxes include all sales, use, transfer, recording,
ad valorem, bulk sales and other similar taxes and fees, arising out of or in
connection with the transactions contemplated by this Agreement. The party
which has primary responsibility for the payment of any particular Transfer
Tax shall prepare and file the relevant Tax Return, pay the Transfer Taxes
shown on such Return, and notify the other party in writing of the Transfer
Taxes shown on such Tax Return and how such Transfer Taxes were calculated;
the other party shall, within 5 days of the receipt of such notice, pay to the
first party its share of such Transfer Taxes.

Section 6.24 HSR Approval.  If the lowest closing bid price of Concurrent
Common Stock is greater than $1.50 per share on the date that the Proxy
Statement is mailed to shareholders of Concurrent and Harris, each of the
parties hereto agrees to use its Best Efforts to take, or cause to be taken,
and to do, or cause to be done, all things necessary to promptly prepare and
file the pre-merger notification report form and to seek early termination or
expiration of the waiting period under the HSR Act.

(iii) In applying Section 12.4 of the Harris 401(k) Plan, Harris

Business Employees as of the Employment Effective Time. As a result of
said partial termination, each Business Employee shall be fully vested

   any Business Employee who becomes an employee of Concurrent ("Hired
   Business Employee") to such Hired Business Employee until the
   termination of his employment with Concurrent. Concurrent shall notify
   Harris of the termination of the employment of any Hired Business
   Employee no later than five days following the date on which such
   Hired Business Employee's employment with Concurrent terminates.

premiums necessary to provide the benefits to which the Business
Employees are entitled, under the terms of the Welfare and Fringe Benefit

representations and warranties of the parties contained in this Agreement or
any certificate delivered in connection herewith shall not survive the
Closing. The covenants and agreements of the parties hereto shall survive the
Closing if and to the extent so provided in such covenant or agreement.

Section 10.2 Indemnification.

Subject to the other provisions of this Article X, from and after the
Closing:

(a) Harris shall indemnify and hold harmless Concurrent and its
affiliates, and each of their affiliates' and their respective affiliates'
directors, officers, employees, representatives and agents, and each of the
heirs, executors, successors and assigns of any of the foregoing
(collectively, the "Representatives") from and against any costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages and amounts paid in settlement (collectively, "Damages") to the extent
they are the result of (i) any breach of any representation or warranty made
by or on behalf of Harris under this Agreement that is a result of fraud or
intentional or wilful misrepresentation by Harris or (ii) the Excluded
Liabilities. As to claims for Damages by Concurrent and its Representatives in
respect of misrepresentations pursuant to clause (i) of this Section 10.2(a),
such claims, to the extent practicable, shall be satisfied by reductions in
the Liquidation Preference for the Outstanding Preferred Stock Consideration
pursuant to the terms of the Certificate of Designation.

(b) Concurrent shall indemnify and hold harmless Harris and its
Representatives from and against any Damages to the extent they arise out of
and are the result of (i) any breach of any representation or warranty made by
or on behalf of Concurrent under this Agreement that is a result of fraud or
intentional or wilful misconduct by Concurrent or (ii) the Assumed
Liabilities. Concurrent and its Representatives, on the one hand, and Harris
and its Representatives, on the other hand, as the case may be, are referred
to herein as the "Indemnified Parties."

(c) Neither Harris nor Concurrent, as the case may be, shall be obligated
to indemnify a party pursuant to this Article X for any Damages pursuant to
Sections 10.2(a)(i) and 10.2(b)(i) unless Harris or Concurrent, as the case
may be, shall have received written notice of such Damages (i) in the case of
a breach of a representation and warranty (other than the representations and
warranties set forth in Sections 4.10 and 5.11, as the case may be), within 2
years from the Closing Date and (ii) in the case of the representations and
warranties set forth in Sections 4.10 and 5.11, as the case may be, prior to
the expiration of the applicable statute of limitations; provided, however, in
the event that an Indemnified Party (x) receives notice of any matter which
provides a reasonable basis for a claim to indemnification hereunder and
within the applicable period provided in this Section 10.2(c) and (y) provides
notice to the Indemnifying Party (as defined hereinafter) of the receipt of
such notice, then such Indemnified Party shall be entitled to indemnification
with respect to such claim until its final resolution, and provided, further,
that there shall be no period of time within which notice of or a claim for
indemnity must be provided by an Indemnified Party to an Indemnifying Party
(as defined in Section 10.3(a)) with respect to those items set forth in
Section 10.2(a)(ii) and 10.2(b)(ii) hereof.

Section 10.3 Claims.

(a) If an Indemnified Party intends to seek indemnification pursuant to
this Article X, such Indemnified Party shall promptly notify Harris or
Concurrent, as the case may be (the "Indemnifying Party"), in writing of such
claim describing such claim in reasonable detail; provided, however, that the
failure to provide such notice shall not affect the obligations of the
Indemnifying Party unless it is actually prejudiced thereby, subject, however,
to the time periods specified in Section 10.1 hereof. In the event that such
claim involves a claim by a third party against the Indemnified Party, the
Indemnifying Party shall have 30 days after receipt of such notice to decide
whether it will undertake, conduct and control, through counsel of its own
choosing and at its own expense, the settlement or defense thereof, and if it
so decides, the Indemnified Party shall cooperate with it in connection
therewith; provided, however, that the Indemnified Party may participate in
such settlement or defense through counsel chosen by it; and provided,
further, however, that the fees and expenses of such counsel shall be borne by
the Indemnified Party. The decision by an Indemnifying Party to undertake the
defense or settlement of such claim shall be conclusive evidence of its
concurrence that any Indemnified Party involved in such claim is entitled to
indemnification hereunder with respect to such claim. Notwithstanding anything
in this Section 10.3(a) to the contrary, the Indemnifying Party may, without
the consent of the Indemnified Party, settle or compromise any action or
consent to the entry of any judgment which includes as an unconditional term
thereof the delivery by the claimant or plaintiff to the Indemnified Party of
a duly executed written release of the Indemnified Party from all liability in
respect of such action, which release shall be reasonably satisfactory in form
and substance to counsel for the Indemnified Party; provided, however, that
the Indemnifying Party shall not, without the written consent of the
Indemnified Party, settle or compromise any action in any manner that, in the
reasonable judgment of the Indemnified Party or its counsel, would materially
and adversely affect the Indemnified Party, other than as a result of money
damages or other money payments. If the Indemnifying Party does not notify the
Indemnified Party within 30 days after the receipt of the Indemnified Party's
notice of a claim of indemnity hereunder that it elects to undertake the
defense thereof, the Indemnified Party shall have the right to contest, settle
or compromise the claim but shall not thereby waive any right to indemnity
therefor pursuant to this Agreement. So long as the Indemnifying Party is
contesting any such claim in good faith, the Indemnified Party shall not pay
or settle any such claim. Notwithstanding the foregoing, the Indemnified Party
shall have the right to pay or settle any such claim; provided, however, that
so long as the Indemnifying Party is contesting such claim in good faith, any
such settlement shall include as an unconditional term thereof the delivery by
the claimant or plaintiff to the Indemnifying Party of a duly executed written
release of the Indemnifying Party from all liability in respect of such
action; and provided, further, however, that in such event it shall waive any
right to indemnity therefor by the Indemnifying Party; and provided, further,
however, that the Indemnified Party shall provide the Indemnifying Party
reasonable advance notice of any proposed settlement or payment and shall not
pay or settle any claim if the Indemnifying Party shall reasonably object.
 
(b) The Indemnified Party shall cooperate fully in all aspects of any
investigation, defense, pretrial activities, trial, compromise, settlement or
discharge of any claim in respect of which indemnity is sought pursuant to
Article X, including, but not limited to, by providing the other party with
reasonable access to employees and officers (including as witnesses) and other
information.
