          Series B Preferred Stock, Series C Preferred Stock and

          options, warrants or agreements granted or issued by or
          binding upon the Company for the purchase or acquisition
          of any shares of capital stock of the Company or any
          other securities convertible into, exchangeable for or
          evidencing the right to subscribe for any shares of such
          capital stock.  The Company is not subject to any
          obligation (contingent or otherwise) to repurchase or
          otherwise acquire or retire any shares of the capital
          stock of the Company or any convertible securities,
          rights or options of the type described in the preceding
          sentence.  The Company is not a party to, and does not
          have knowledge of, any agreement expressly restricting
          the transfer of any shares of the capital stock of the
          Company.

                    (d)  No Subsidiaries or Other Ventures.  The

          necessary corporate action on the part of the Company. 
          When issued and paid for as provided in this Agreement,
          the Preferred Shares will be validly issued and
          outstanding, fully paid and nonassessable, and the
          issuance of such Preferred Shares is not and will not be
          subject to preemptive rights of any other stockholder of
          the Company.  The shares of Common Stock to be issued
          upon conversion of the Preferred Shares and upon exercise
          of the New Warrants and the Revised Warrants have been
          duly authorized by all necessary corporate action on the
          part of the Company and, as of the Closing, will be duly
          reserved for issuance.  When the shares of Common Stock
          are issued upon conversion of the Preferred Shares and
          upon exercise of the New Warrants and the Revised
          Warrants, such shares will be validly issued and
          outstanding, fully paid and nonassessable and the
          issuance of such shares will not be subject to preemptive
          rights of any other stockholder of the Company.

                    (f)  Financial Statements.  (1) The Company has
          heretofore delivered or made available to the Purchaser
          the audited consolidated balance sheets at June 30, 1995,
          1994 and 1993 of the Company and the related consolidated
          statements of income, stockholders' equity and cash flows
          for the years then ended, including the related notes and
          auditor's report thereon (the "Financial Statements"). 
          The Financial Statements (i) present fairly the
          consolidated financial condition of the Company at the
          dates thereof and present fairly its consolidated results
          of operations and cash flows for the years then ended and
          (ii) have been prepared in conformity with generally
          accepted accounting principles ("GAAP") applied
          consistently with respect to the immediately preceding
          fiscal year period except as set forth in the notes to
          the Financial Statements or in the auditor's report
          thereon.

                    (2) The Company has heretofore delivered or
          made available to the Purchaser the unaudited
          consolidated balance sheet at September 30, 1995 of the
          Company (the "September Balance Sheet") and the related
          consolidated statements of income and cash flows for the
          three months then ended (such September Balance Sheet and
          related consolidated statements, collectively, the
          "September Financial Statements"), each of which (i)
          presents fairly, in all material respects, the
          consolidated financial condition of the Company at
          September 30, 1995, and presents fairly  its consolidated
          results of operations and cash flows for the nine months
          then ended and (ii) has been prepared in compliance with
          all of the requirements of Section 15(d) of the
          Securities Exchange Act of 1934, as amended, (the
          "Exchange Act") and the applicable rules and regulations
          thereunder.

                    (g)  SEC Reports.  The Company has filed all
          reports, statements, forms and documents with the
          Securities Exchange Commission ("SEC") that it was
          required to file since December 31, 1990 (the "SEC
          Reports"), all of which have complied in all material
          respects with all applicable requirements of the
          Securities Act of 1933, as amended (the "Securities
          Act"), and the Exchange Act.  As of their respective
          dates, each such report, statement, form or document,
          including without limitation any financial statements or
          schedules included therein, did not contain any untrue
          statement of a material fact or omit to state a material
          fact required to be stated therein or necessary to make
          the statements therein, in light of the circumstances
          under which they were made, not misleading.

                    (h)  Liabilities.  As of the date hereof,
          except (i) as set forth on the September Balance Sheet,
          (ii) as set forth in Section 3(h) of the Disclosure
          Schedule or (iii) for liabilities or obligations which
          were incurred after September 30, 1995 in the ordinary
          course of business and consistent with past practices,
          the Company has no liabilities, obligations, claims or
          losses (whether liquidated or unliquidated, secured or
          unsecured, absolute, accrued, contingent or otherwise)
          that would be required to be disclosed on a consolidated
          balance sheet of the Company (including the notes
          thereto) in conformity with GAAP.

                    (i)  Indebtedness of the Company.  Section 3(i)
          of the Disclosure Schedule sets forth all outstanding
          secured and unsecured Indebtedness (as defined
          hereinafter) of the Company in excess of $50,000 in any
          individual case, or for which the Company has
          commitments, on the date of this Agreement.  The Company
          is not in default with respect to any such Indebtedness. 
          "Indebtedness" means at any time, (i) all indebtedness
          for borrowed money, (ii) all obligations evidenced by
          bonds, debentures, notes or other similar instruments,
          (iii) all reimbursement obligations and other liabilities
          under letters of credit, (iv) all obligations to pay the
          deferred purchase price of property or services, other
          than normal trade creditors in the ordinary course, (v)
          all obligations in respect of capitalized leases, (vi)
          all guarantees and contractual obligations of the
          Company, contingent or otherwise, with respect to any
          indebtedness or obligation of another, and (vii) all
          obligations of the Company secured by any mortgage,
          pledge, lien, security interest or other encumbrance on
          any asset or property of the Company, whether or not such
          obligation has been assumed.

                    (j)  Title to Properties; Liens.  The Company
          does not own any real property.  Section 3(j) of the
          Disclosure Schedule correctly describes all real property
          leased by the Company, together with a description of the
          lease payment obligations and lease termination
          provisions relating thereto.  The Company enjoys peaceful
          and undisturbed possession under all leases necessary in
          any material respect for the operation of its properties
          and assets, and all such leases are valid and subsisting
          and are in full force and effect.

                    (k)  Actions Pending. There is no action, suit,
          claim, investigation or proceeding pending or, to the
          knowledge of the Company, threatened, against the Company
          which questions the validity of this Agreement or the
          Related Agreements or any action taken or to be taken
          pursuant hereto or thereto.  There is no action, suit,
          claim, investigation or proceeding pending or, to the
          knowledge of the Company, threatened, against or
          involving the Company or any of its properties or assets. 
          There are no outstanding orders, judgments, injunctions,
          awards or decrees of any court, arbitrator or
          governmental or regulatory body against the Company.

                    (l)  Compliance with Law.  The business of the
          Company has been and is presently being conducted so as
          to comply with all applicable federal, state, and local
          governmental laws, rules, regulations and ordinances. 
          The Company has all material franchises, permits,
          licenses, consents and other governmental or regulatory
          authorizations and approvals necessary for the conduct of
          its business as now being conducted by it, and the
          Company is in compliance therewith except for any non-
          compliances which would not, individually or in the
          aggregate, have a Company Material Adverse Effect. 

                    (m)  No Violations.  The Company is not in
          violation of or default under (i) any term of its
          Certificate of Incorporation or By-Laws, (ii) any of its
          contracts or agreements or under any instrument by which
          the Company is bound, or (iii) any outstanding indenture
          or other debt instrument or with respect to the payment
          of principal of or interest on any outstanding
          obligations for borrowed money.

                    (n)  Taxes.

                         (i)  The Company has duly and timely
               filed, or caused to be filed, and will duly and
               timely file, or cause to file, with the appropriate
               taxing authority all Tax Returns (as defined below)
               required to be filed on or before the date hereof by
               or with respect to the Company and such Tax Returns
               were or will be true, correct and complete in all
               material respects when filed.

               paid in full or has made adequate provision for on
               its balance sheet all material Taxes (as defined
               below) shown to be due on such Tax Returns.  There
               are no liens for Taxes upon the assets of either the
               Company except for statutory Liens for current Taxes
               not yet due.

                         (iii)  None of the Tax Returns filed by or
               on behalf of the Company has been examined by the
               appropriate taxing authorities.

                         (iv) Except as set forth in Schedule
               3(n)(iv) hereto, the Company has not received any
               notice of deficiency or assessment from any taxing
               authority with respect to liabilities or obligations
               for Taxes with respect to the Company which has not
               been fully paid or finally settled, and any such
               deficiency or assessment shown in Schedule 3(n)(iv)
               hereto is being contested in good faith through
               appropriate proceedings.  The Company has not given
               any outstanding waivers or comparable consents
               extending the application of the statute of
               limitations with respect to any Taxes or Tax Returns
               with respect to the Company.

                         (v)  The Company has complied in all
               material respects with all applicable laws, rules
               and regulations relating to the payment and

                         (vi) No audit or other administrative
               proceeding or court proceeding which is material to
               the financial condition of Company is presently
               pending with regard to any Taxes or Tax Returns.

                         (vii)  The amount and character of the tax
               loss carryforwards as set forth in the Company's
               financial statements for the year ending June 30,
               1995 are materially accurate and, to the Company's
               best knowledge, are not subject to any "Section 382
               limitation" under Section 382 of the Code, and any
               regulations promulgated thereunder.  To the
               Company's best knowledge, at the Closing Date, the
               issuance of the Preferred Shares, the Warrants and
               the Fee Warrants in accordance with the terms of
               this Agreement and the Related Agreements will not
               result in an "ownership change" under Section 382 of
               the Code, and any regulations promulgated
               thereunder.  As of the Closing Date, the Company
               shall not have any plan or intention to take any
               action after the Closing Date, which to its best
               knowledge would result in an "ownership change"
               under Section 382 of the Code and any regulations
               promulgated thereunder.

                           (viii)  For purposes of this Agreement,
               "Taxes" shall mean any and all taxes, charges, fees,
               levies or other like assessments (and all related
               interest, additions to tax and penalties),
               including, but not limited to, income, transfer,
               gains, gross receipts, excise, inventory, property
               (real, personal or intangible), custom, duty, sales,
               use, license, withholding, payroll, employment,
               capital stock and franchise taxes, imposed by the
               United States, or any state, local or foreign taxing
               authority, whether computed on a unitary, combined
               or any other basis and "Tax Return" shall mean any
               report, return or other information filed with any
               taxing authority with respect to Taxes imposed upon
               or attributable to the operations of the Company.

                    (o)  ERISA.  Section 3(o) of the Disclosure
          Schedule contains a true and complete list of each
          employee benefit plan, as defined in Section 3(3) of the
          Employee Retirement Income Security Act of 1974, as
          amended ("ERISA"), and any other bonus, severance or
          termination pay, stock option or stock purchase,
          incentive pay or other plan, program or arrangement
          covering present or former employees of the Company which
          is maintained or contributed to by the Company or any of
          its subsidiaries (the "Plans").  None of the Plans is
          subject to the provisions of Title IV of ERISA, and none
          of the Plans is a multiemployer Plan as defined in
          Section 3(37) of ERISA (a "Multiemployer Plan").  The
          Company has not incurred (directly or indirectly) any
          liability to the Pension Benefit Guaranty Corporation or
          with respect to a Multiemployer Plan.  None of the Plans
          is subject to the minimum funding standards set forth in
          Section 302 of ERISA or Section 412 of the Internal
          Revenue Code of 1986, as amended (the "Code").  None of
          the Company or any of its officers or employees has
          engaged in a "prohibited transaction" as defined in
          Section 406 of ERISA or Section 4975 of the Code with
          respect to any Plan which would subject any of such
          parties to a civil penalty under Section 502(i) of ERISA
          or an excise tax under Section 4975 of the Code.  Each of
          the Plans has been operated in all material respects in
          accordance with applicable law, including ERISA and the
          Code.  None of the Plans is an employee welfare plan, as
          defined in Section 3(1) of ERISA, which provides health
          or life insurance benefits to employees of the Company
          following their retirement (other than coverage mandated
          by applicable law).  Each Plan that is intended to be
          qualified under Section 401(a) of the Code is so
          qualified.

                    (p)  Absence of Specified Changes.  Except as
          set forth in Section 3(p) of the Disclosure Schedule,
          during the period from June 30, 1995 to the date hereof,
          there has not been any:

                         (1)  material adverse change in the
          business, condition or results of operations of the
          Company;

                         (2)  transactions involving the Company
          except in the ordinary course of business;

                         (3)  change in accounting principles,
          methods or practices of the Company;

                         (4)  amendment to the Certificate of
          Incorporation or By-Laws of the Company; or

                         (5)  agreement or understanding to take
          any of the actions described above in this paragraph.

                    (q)  Certain Fees.  No broker's, finder's or
          financial advisory fees or commissions will be payable by
          the Company with respect to the transactions contemplated
          by this Agreement and the Related Agreements.

                    (r)  Use of Proceeds.  The Company will apply
          the proceeds from the sale of the Series F Preferred
          Shares, the Series G Preferred Shares and the New
          Warrants to general working capital purposes.

                    (s)  Intellectual Property Rights.

                         (i)  The Company is the owner of or has
               rights to use (including the right to sue for past
               infringement) the intellectual and similar property
               of every kind and nature used at any time in or
               necessary for the conduct of its business, including
               without limitation, (A) Patents (meaning all United
               States and foreign patents and patent applications,
               patent disclosures and inventions, and all patents
               issued upon said patent applications or based upon
               said disclosures and inventions, including all
               reissues, divisions, continuations, continuations-
               in-part, substitutions, extensions or renewals of
               any of the foregoing), (B) Trademarks (meaning all
               United States, any political subdivision thereof,
               and foreign trademarks, service marks, trade names,
               corporate names, company names, business names,
               fictitious business names, trade styles, logos,
               designs and general intangibles of like nature, all
               registrations and recordings thereof, and all
               applications in connection therewith, including
               registrations, recordings and applications in the
               United States Patent and Trademark Office (the
               "PTO"), any State of the United States or any other
               country or jurisdiction or any political subdivision
               thereof, and all goodwill symbolized thereby and/or
               associated therewith and all extensions or renewals
               thereof,), (C) Copyrights (meaning all copyrights,
               United States and foreign copyright registrations,
               and applications to register copyrights), (D)
               inventions, formulae, processes, designs, know-how,
               show-how or other data or information, (E)
               confidential or proprietary technical and business
               information, processes and trade secrets, (F)
               computer software and databases (including all
               embodiments or fixations thereof and related
               documentation, registrations and franchises, and all
               additions, improvements, enhancements, updated and
               accessions thereto), (G) all technical manuals and
               documentation made or used in connection with any of
               the foregoing, and (H) all licenses and rights with
               respect to the foregoing or property of like nature,
               in each case as any of the foregoing have been at
               any time used in or necessary for the conduct of the
               business of the Company (collectively, the
               "Intellectual Property Rights").

                         (ii) Section 3(s)(ii) of the Disclosure
               Schedule sets forth a complete and accurate list of
               all Copyrights, Patents, and Trademarks owned by or
               under obligation of assignment to the Company.  Each
               owner identified thereon is listed in the records of
               the appropriate United States, State or foreign
               agency as the sole owner of record.

                         (iii)  Section 3(s)(iii) of the Disclosure
               Schedule sets forth a complete and accurate list of
               (a) all material agreements and (b) all other
               agreements entered into since January 1, 1990, in
               each case between the Company and any third party
               granting any right to use or practice any rights
               under any Intellectual Property Right (collectively,
               the "Intellectual Property Licenses"), except for
               single-user licenses granting the right to use on a
               single personal computer a single copy of
               application software incorporating any of the
               Company's Intellectual Property Rights.

                         (iv) There is no restriction or limitation
               on the right of the Company to transfer any of the
               Intellectual Property Rights.

                         (v)  No trade secret, formula, process,
               invention, design, know-how, show-how or any other
               confidential information relating to the Company's
               business has been disclosed or authorized to be
               disclosed to any third party unless any such third
               party has entered into, or is bound by, a
               confidentiality agreement that is sufficient to
               protect fully the Company's proprietary interest and
               right in and to such Intellectual Property Right.

                         (vi) The use of the Intellectual Property
               Rights by the Company is not in conflict with the
               rights of others.  There are no pending legal or
               governmental proceedings, including oppositions,
               interferences, proceedings or suits, relating to the
               Intellectual Property Rights, and, to the best
               knowledge of the Company, no such proceedings are
               threatened.  To the best knowledge of the Company,
               the conduct of the business of the Company and the
               exercise of the Intellectual Property Rights does
               not infringe upon or otherwise violate, and the
               exercise of any rights granted to the Company under
               any Intellectual Property License would not infringe
               upon or violate any intellectual property rights of
               any third party.  To the best knowledge of the
               Company, except as set forth in Section 3(s)(vi), no
               person is infringing upon or otherwise violating any
               of the Intellectual Property Rights.  None of the
               Company or its affiliates has received notice of any
               claims, and there are no pending claims, of any
               persons relating to the scope, ownership or use of
               any of the Intellectual Property Rights.

                         (vii)  Each copyright registration,
               patent, and registered trademark and application
               therefor listed in Section 3(s)(ii) of the
               Disclosure Schedule is valid, subsisting and in
               proper form, and has been duly maintained, including
               the submission of all necessary filings in
               accordance with the legal and administrative
               requirements of the appropriate jurisdictions. 
               There have been no failures in complying with such
               requirements.  No such Copyright, Patent or
               Trademark has lapsed and there has been no
               cancellation or abandonment thereof.  

                         (viii)  With respect to each patent and
               patent application listed in Section 3(s) of the
               Disclosure Schedule, there are no defects of form in
               the preparation or filing of the applications
               thereof.  Each pending application is being
               diligently prosecuted.  During the prosecution of
               each Patent, (A) all pertinent prior art references
               known to the Company or its counsel was properly
               disclosed to the PTO, and (B) neither such counsel
               nor the Company made any misrepresentation to, or
               concealed any material fact from, the PTO.

                         (ix) The execution and delivery of this
               Agreement and the Related Agreements and the taking
               of the actions contemplated hereby and thereby will
               not alter any of the rights of the Company in or to
               the Intellectual Property Rights.

                    (t)  Environmental Matters.  The Company is in
          compliance with the provisions of all federal, state and
          local laws relating to pollution or protection of the
          environment applicable to it or to real property leased
          by it or to the use, operation or occupancy thereof,
          except for violations or liabilities which individually
          or in the aggregate could not reasonably be expected to
          have a Company Material Adverse Effect.  The Company has
          not engaged in any activity in violation of any provision
          of any federal, state or local law relating to pollution
          or protection of the environment, which violation could
          reasonably be expected to have a Company Material Adverse
          Effect.  The Company has no liability, absolute or
          contingent, under any federal, state or local law
          relating to pollution or protection of the environment,
          except for liabilities which individually or in the
          aggregate could not reasonably be expected to have a
          Company Material Adverse Effect.

                    (u)  Registration Rights.  Except as set forth
          in Section 3(u) of the Disclosure Schedule, the Company
          is not a party to any agreement granting registration
          rights to any person with respect to any of its equity or
          debt securities.

                    (v)  Agreements.  Section 3(v) of the
          Disclosure Schedule contains a list of each agreement or
          instrument (including any and all amendments thereto) to
          which the Company is a party as of the date hereof and
          which is or, immediately following the consummation of
          the transactions contemplated by this Agreement, will be,
          material to the business, condition or results of
          operations of the Company.  Each such agreement or
          instrument (including any and all amendments thereto) is
          in full force and effect and constitutes a legal, valid
          and binding obligation of (i) the Company and (ii) to the
          best knowledge of the Company, the other respective
          parties thereto, and, to the best knowledge of the
          Company, no person is in default or breach of (with or
          without the giving of notice or the passage of time) any
          such agreement or instrument.

                    (w)  Availability of Documents.  Section 3(w)
          of the Disclosure Schedule contains a true, correct and
          complete copy of the Company's Certificate of
          Incorporation, together with all amendments thereto.  The
          Company has also heretofore provided or made available to
          the Purchaser an accurate copy of its by-laws and has
          heretofore made available for inspection by the Purchaser
          all written agreements, arrangements, commitments and
          documents referred to herein or in the Disclosure
          Schedule, in each case, together with all amendments and
          supplements thereto.  The Company has heretofore made
          available for inspection by the Purchaser its corporate
          minute books.  Such corporate minute books contain the
          minutes of all the meetings of stockholders, board of
          directors and any committees thereof which have been held
          since the Company's date of incorporation and all written
          consents to action executed in lieu thereof.

                    (x)  Business Relations.  To the knowledge of
          the Company, no client, customer or supplier will cease
          to do business with the Company due to the consummation
          of the transactions contemplated by this Agreement or the
          Related Agreements.

                    (y)  Interest in Competitors, Suppliers,
          Customers, etc.  Except as set forth on Section 3(y) of
          the Disclosure Schedule or with respect to the ownership
          of less than 1% of the outstanding publicly traded
          securities of an entity, neither the Company nor its
          officers, directors, or affiliates have any ownership
          interest in any competitor, supplier, customer or
          franchisee of the Company.

                    (z)  Private Offering.  Assuming the accuracy
          of the Purchaser's representations set forth in Section
          4(c) herein, the offer and sale of the Shares hereunder
          is exempt from the registration and prospectus delivery
          requirements of the Securities Act.  Neither the Company
          nor any person acting on behalf of it has taken or will
          take any action which would subject the offering and
          issuance of any of such securities to the provisions of
          Section 5 of the Securities Act or to the provisions of
          any securities law, rule or regulation of any applicable
          jurisdiction.

                    (aa)  Disclosure.  No representation or
          warranty to Purchaser contained in this Agreement and no
          statement contained in the Disclosure Schedule or any
          Officer's Certificate of the Company furnished pursuant
          to the provisions hereof, contains any untrue statement
          of a material fact or omits to state a material fact
          necessary in order to make the statements contained
          therein not misleading.

          4.  REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS.

                    Each Purchaser represents and warrants,
          severally and not jointly, to the Company as follows:

                    (a)  Organization and Standing of the
          Purchasers.  The Purchaser is a partnership duly
          organized, validly existing and in good standing (to the
          extent such concept exists) under the laws of the
          jurisdiction of its organization.

                    (b)  Authority; Enforceability; No Conflict. 
          The Purchaser has all requisite power and authority
          (corporate or otherwise) to enter into this Agreement and
          to carry out its obligations hereunder.  The execution,
          delivery and performance of this Agreement by the
          Purchaser have been duly and validly authorized by all
          requisite partnership proceedings on the part of the
          Purchaser.  This Agreement is a valid and binding
          obligation of the Purchaser, enforceable against it in
          accordance with its terms, except that (i) such
          enforcement may be subject to bankruptcy, insolvency,
          reorganization, moratorium, rehabilitation, liquidation,
          conservatorship, receivership or other similar laws now
          or hereafter in effect relating to creditors' rights
          generally and (ii) the remedy of specific performance and
          injunctive and other forms of equitable relief may be
          subject to equitable defenses and to the discretion of
          the court before which any proceeding therefor may be
          brought.  The execution and delivery of this Agreement by
          the Purchaser do not, and consummation by the Purchaser
          of the transactions contemplated hereby will not, result
          in or constitute (i) a default, breach or violation of or
          under the organizational documents of the Purchaser, or
          (ii) a default, breach or violation of or under any
          mortgage, deed of trust, indenture, note, bond, license,
          lease agreement or other instrument or obligation to
          which the Purchaser is a party or by which any of its
          properties or assets are bound, except for any defaults,
          breaches or violations which would not, individually or
          in the aggregate, have a material adverse effect on the
          Purchaser or prevent or materially delay the consummation
          by the Purchaser of the transactions contemplated hereby,
          or (iii) a violation of any statute, rule, regulation,
          order, judgment or decree of any court, public body or
          authority, except for any violations which would not,
          individually or in the aggregate, have a material adverse
          effect on the Purchaser or prevent or materially delay
          the consummation by the Purchaser of the transactions
          contemplated hereby.

                    (c)  Acquisition for Investment.  The Purchaser
          is either an "accredited investor," as that term is
          defined in SECTION230.501(a) of the rules and regulations
          promulgated by the SEC under the 1933 Act or a person
          described in SECTION230.506(b)(ii) of such rules and
          regulations.  The Purchaser is acquiring the Preferred
          Shares, the New Warrants and, in the case of Wand III,

          6.  ADDITIONAL AGREEMENTS.

                    (a)  Access to Information; Confidentiality. 
          From the date hereof to the Closing, the Company shall
          afford the officers, employees and agents of the
          Purchasers access during normal business hours to the
          Company's officers, employees, agents, properties,
          offices and all books and records of the Company, and
          shall furnish the Purchasers with all financial,
          operating and other data and information concerning the
          Company as the Purchaser, through its officers, employees
          or agents, may request and shall cooperate fully with the
          Purchasers and their representatives in their examination
          of the Company.

                    Each Purchaser will, and will cause its
          respective affiliates, partners, directors, officers,
          employees, agents, representatives and financial advisors
          (collectively, "Representatives") to, hold in strict
          confidence all Confidential Information (as hereinafter
          defined), and not disclose the same to any person without
          the prior consent of the Company, unless compelled to
          disclose any such Confidential Information by judicial or
          administrative process or, in the written opinion of
          their counsel, by other requirements of law.  Prior to
          disclosing any Confidential Information to any such
          person, the Purchasers will inform such person and its
          representatives of the confidential nature thereof and
          will obtain from such person its agreement to be bound by
          the provisions of this paragraph as if references herein
          to the Purchaser  were references to such person.  If
          this Agreement is terminated, each Purchaser will
          promptly return to the Company or destroy all documents
          (including all copies thereof) furnished by the Company
          and received by such Purchaser or any of its
          Representatives containing such Confidential Information. 
          For purposes hereof, "Confidential Information" shall
          mean all confidential nonpublic information concerning
          the Company that the Purchaser obtains from the Company,
          or its representatives, excluding any such information
          that subsequently becomes publicly available (other than
          directly or indirectly through acts of the Purchaser.)

                    (b)  Best Efforts.  Subject to the terms and
          conditions herein provided, each of the parties hereto
          agrees to use its best efforts to take, or cause to be
          taken, all actions, and to do, or cause to be done, all
          things reasonably necessary, proper or advisable under
          applicable laws and regulations to consummate and make
          effective the transactions contemplated by this Agreement
          and the Related Agreements as promptly as practicable. In
          case at any time after the Closing any further action is
          necessary or desirable to carry out the purposes of this
          Agreement and the Related Agreements, the proper officers
          and directors of each party hereto shall take all such
          necessary action.

                    (c)  Public Announcements.  The Purchasers and
          the Company will consult with each other before issuing
          any press release or otherwise making any public
          statements with respect to the transactions contemplated
          by this Agreement and the Related Agreements, and shall
          not issue any such press release or make any such public
          statement prior to such consultation, except as may be
          required by applicable law.  Except as may be required by
          applicable law, the Company shall not disclose the
          identify of any Purchaser in any such press release or
          other public statement without the prior written consent
          of such Purchaser.

                    (d)  Supplements to Disclosure Schedule.  Prior
          to the Closing, the Company will supplement or amend the
          Disclosure Schedule with respect to any matter hereafter
          arising which, if existing or occurring at the date of
          this Agreement, would have been required to be set forth
          or described in the Disclosure Schedule.  No supplement
          or amendment of the Disclosure Schedule made pursuant to
          this section shall be deemed to cure any breach of any
          representation or warranty made in this Agreement unless
          the Purchasers specifically agrees thereto in writing.

                    (e)  Directors.  For so long as the Purchasers
          shall own, in the aggregate, Common Stock (or Preferred
          Shares convertible into Common Stock) equal to or
          exceeding five percent of the then outstanding Common
          Stock of the Company, the Purchaser shall be entitled to
          propose two candidates (the "Purchaser Designees") for
          election to the Board of Directors of the Company. 
          Subject to its fiduciary duties to shareholders, the
          Company will recommend to its shareholders that the
          Purchaser Designees be elected to the Company's Board of
          Directors.

          jurisdiction which prohibits the consummation of any of
          the transactions contemplated by this Agreement.

                         (i)  at any time by mutual written consent
          of the Company and the Purchasers;

                         (ii)  by either the Company or the
          Purchaser if the Closing shall not have occurred by March
          1, 1996; provided, however, that the right to terminate
          this Agreement under this Section 10(a)(ii) shall not be
          available to any party whose failure to fulfill any

          before such date; or

                          (iii)  by either the Company or the
          Purchasers if a court of competent jurisdiction shall
          have issued an order, decree or ruling permanently
          restraining, enjoining or otherwise prohibiting the
          transactions contemplated by this Agreement, and such
          order, decree, ruling or other action shall have become
          final and nonappealable.

                    (b)  Obligations to Cease.  In the event that
          this Agreement shall be terminated pursuant to Section

          this Agreement shall terminate and there shall be no
          liability of any party hereto to any other party except
          that (i) the provisions of the second paragraph of
          Section 6(a), Section 11, and Section 12(g) shall
          survive, and shall be and remain in full force and effect
          and (ii) nothing herein will relieve any party from
          liability for any willful breach of this Agreement.

          11.  INDEMNIFICATION.

                    (a)  General Indemnity.  The Company agrees to
          indemnify and save harmless the Purchasers (and their
          respective directors, officers, partners, affiliates,
          representatives, advisors, successors and assigns) from
          and against any and all losses, liabilities,
          deficiencies, costs, damages and expenses (including,
          without limitation, interest, penalties, reasonable
          attorneys' fees, charges and disbursements) incurred by
          the Purchasers as a result of (i) any breach of the
          representations, warranties or covenants made by the
          Company herein or in the Related Agreements or (ii) any
          action, proceeding or claim commenced or threatened by a
          third party in connection with this Agreement, the
          Related Agreements and the transactions contemplated
          hereby and thereby.  Each Purchaser agrees to indemnify
          and save harmless the Company (and its directors,
          officers, partners, affiliates, representatives,
          advisors, successors and assigns) from and against any
          and all losses, liabilities, deficiencies, costs, damages
          and expenses (including, without limitation, interest,
          penalties, reasonable attorneys' fees, charges and
          disbursements) incurred by the Company as a result of any
          breach of the representations, warranties or covenants
          made by such Purchaser herein or in the Related
          Agreements.  No party shall be entitled to
          indemnification hereunder unless and until the aggregate
          amount of such party's indemnification claims exceeds
          $15,000 and then to the full extent of such claims.

                    (b)  Indemnification Procedure.  Any party
          entitled to indemnification under this Section 11 (an
          "indemnified party") will give prompt written notice to
          the indemnifying party of any claim with respect to which
          it seeks indemnification promptly after the discovery by
          such party of any matters giving rise to a claim for
          indemnification; provided that the failure of any party
          entitled to indemnification hereunder to give notice as
          provided herein shall not relieve the indemnifying party
          of its obligations under this Section 11 except to the
          extent that the indemnifying party is actually prejudiced
          by such failure to give notice.  In case any action,
          proceeding or claim is brought against an indemnified
          party in respect of which indemnification is sought
          hereunder, the indemnifying party shall be entitled to
          participate in and, unless in the reasonable judgment of
          the indemnified party a conflict of interest between it
          and the indemnifying party may exist in respect of such
          action, proceeding or claim, to assume the defense
          thereof, with counsel reasonably satisfactory to the
          indemnified party.  In the event that the indemnifying
          party advises an indemnified party that it will contest
          such a claim for indemnification hereunder, or fails,
          within thirty (30) days of receipt of any indemnification
          notice to notify, in writing, such person of its election
          to defend, settle or compromise, at its sole cost and
          expense, any action, proceeding or claim (or discontinues
          its defense at any time after it commences such defense),
          then the indemnified party may, at its option, defend,
          settle or otherwise compromise or pay such action or
          claim.  In any event, unless and until the indemnifying
          party elects in writing to assume and does so assume the
          defense of any such claim, proceeding or action, the
          indemnified party's costs and expenses arising out of the
          defense, settlement or compromise of any such action,
          claim or proceeding shall be losses subject to
          indemnification hereunder.  The indemnified party shall
          cooperate fully with the indemnifying party in connection
          with any negotiation or defense of any such action or
          claim by the indemnifying party and shall furnish to the
          indemnifying party all information reasonably available
          to the indemnified party which relates to such action or
          claim.  The indemnifying party shall keep the indemnified
          party fully apprised at all times as to the status of the
          defense or any settlement negotiations with respect
          thereto.  If the indemnifying party elects to defend any
          such action or claim, then the indemnified party shall be
          entitled to participate in such defense with counsel of
          its choice at its sole cost and expense.  The
          indemnifying party shall not be liable for any settlement
          of any action, claim or proceeding effected without its
          written consent, provided, however, that the indemnifying
          party shall not unreasonably withhold, delay or condition
          its consent.  Anything in this Section 11 to the contrary
          notwithstanding, the indemnifying party shall not,
          without the indemnified party's prior written consent,
          settle or compromise any claim or consent to entry of any
          judgment in respect thereof which imposes any future
          obligation on the indemnified party or which does not
          include, as an unconditional term thereof, the giving by
          the claimant or the plaintiff to the indemnified party of
          a release from all liability in respect of such claim. 
          The indemnification required by this Section 11 shall be
          made by periodic payments of the amount thereof during
          the course of the investigation or defense, as and when
          bills are received or expense, loss, damage or liability
          is incurred.  The indemnity agreements contained herein
          shall be in addition to (i) any cause of action or
          similar right of the indemnified party against the
          indemnifying party or others, and (ii) any liabilities
          the indemnifying party may be subject to pursuant to the
          law.

          the Company nor the Purchaser shall assign all or any

                    (g)  Governing Law.  THIS AGREEMENT SHALL BE
          CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS
          OF THE STATE OF DELAWARE AS APPLIED TO CONTRACTS MADE AND
          TO BE PERFORMED ENTIRELY IN THE STATE OF DELAWARE.

                    (h)  Entire Agreement.  This Agreement,
          including the Exhibits and Schedules hereto, sets forth
          the entire understanding and agreement of the parties
          hereto relating to the matters set forth herein and

                    (i)  Counterparts.  This Agreement may be
          executed in counterparts, each of which shall be deemed
          an original, and all of which together shall constitute a
          single agreement.

                    (j)  Severability.  In the event that any one
          or more of the provisions contained in this Agreement
          shall for any reason be held to be invalid, illegal or
          unenforceable, the same shall not affect any other
          provision of this Agreement, but this Agreement shall be
          construed in a manner which, as nearly as possible,
          reflects the original intent of the parties.

                    (k)  Words in Singular and Plural Form.  Words

          any document delivered pursuant hereto, and (iii) waive
          compliance with any of the agreements or conditions
          contained herein.  Any agreement on the part of a party
          hereto to any such extension or waiver shall be valid
          only if set forth in an instrument in writing signed by
          the party granting such waiver but such waiver or failure
          to insist upon strict compliance with such obligation,
          covenant, agreement or condition shall not operate as a
          waiver of, or estoppel with respect to, any subsequent or
          future failure.  

                    (n)  Specific Enforcement.  The Purchaser and
          the Company acknowledge and agree that irreparable damage
          would occur in the event that any of the provisions of
          this Agreement were not performed in accordance with
          their specific terms or were otherwise breached.  It is
          accordingly agreed that the parties shall be entitled to

          the terms and provisions hereof in any court of the
          United States or any state thereof having jurisdiction,
          this being in addition to any other remedy to which they
          may be entitled at law or equity.

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

               REGISTRATION RIGHTS AGREEMENT, as amended and
     restated as of January 31, 1996 among Nestor, Inc., a
     Delaware corporation (the "Company"), and the other
     undersigned parties hereto.

               1.   Introduction.  Pursuant to the Securities
     Purchase Agreement (the "Securities Purchase Agreement"),
     dated as of August 1,  1994, between Wand/Nestor
     Investments L.P., a Delaware limited partnership (the
     "Wand/Nestor I Partnership"), and the Company, on August
     1, 1994, the Company issued 1,500 shares of its Series C
     Convertible Preferred Stock, par value $1.00  per share

     Purchase Warrants to purchase 1,000,000 shares of the

     Simultaneously with the Closing of the Securities
     Purchase Agreement, Wand Partners L.P. and Hill &

     Agreement and the Letter of Engagement.  Pursuant to the
     First Amended and Restated Standby Financing and Purchase
     Agreement, dated as of June 30, 1995, between the
     Wand/Nestor I Partnership and the Company, the Company
     issued to the Wand/Nestor I Partnership and to

     Preferred Stock, (ii) 100,000 shares of the Company's
     Common Stock as a commitment fee, (iii) 78,198 shares of
     Common Stock as payment of interest pursuant to the
     Company's four Promissory Notes in the aggregate original
     principal amount of $1,700,000, (iv) Common Stock
     Purchase Warrants to purchase 700,000 shares of Common
     Stock at $1.00 per share as a takedown fee, (v) in

               2.   Registration under Securities Act, etc.

               2.1  Registration on Request.

                    (a)  Request.  At any time or from time
     to time after August 1, 1997, upon the written request
     of one or more Initiating Holders, requesting that the
     Company effect the registration under the Securities Act
     of all or part of such Initiating Holders' Registrable
     Securities and specifying the intended method of
     disposition thereof, the Company will promptly give
     written notice of such requested registration to all
     registered holders of Registrable Securities, and
     thereupon the Company will, subject to the terms of this
     Agreement, effect the registration under the Securities
     Act of:

                         (i)  the Registrable Securities
          which the Company has been so requested to register
          by such Initiating Holders for disposition in
          accordance with the intended method of disposition
          stated in such request;

                         (ii)  all other Registrable
          Securities the holders of which shall have made a
          written request to the Company for registration
          thereof within 30 days after the giving of such
          written notice by the Company (which request shall
               specify the intended method of disposition of such
          Registrable Securities);

                         (iii)  all other shares of Common
          Stock which the Company may elect to register in
          connection with the offering of Registrable
          Securities pursuant to this section 2.1,

     all to the extent requisite to permit the disposition
     (in accordance with the intended methods thereof as
     aforesaid) of the Registrable Securities and the
     additional shares of Common Stock, if any so to be
     registered.  The Company's obligations pursuant to this
     Section 2.1(a) shall cease after two such requested
     registrations shall have been effected in which all of
     the Registrable Securities requested to be included in
     such registration by any holders of Registrable
     Securities shall have been registered. 

                    (b)  Registration Statement Form. 
     Registrations under this section 2.1 shall be on such
     appropriate registration form of the Commission (i) as
     shall be selected by the Company and the holders of more
     than 50% (by number of shares) of the Registrable
     Securities so to be registered and (ii) as shall permit
     the disposition of such Registrable Securities in
     accordance with the intended method or methods of
     disposition specified in their request for such
     registration.  If, in connection with any registration
     under section 2.1 which is proposed by the Company to be
     on Form S-3 or any similar short form registration
     statement which is a successor to Form S-3, the managing
     underwriters, if any, shall advise the Company in
     writing that in their opinion the use of another
     permitted form is of material importance to the success
     of the offering, then such registration shall be on such
     other permitted form.

                    (c)  Expenses.  The Company will pay all
     Registration Expenses in connection with any
     registration requested pursuant to this section 2.1 by
     any Initiating Holders of Registrable Securities prior
     to the time at which two such registrations shall have
     been effected in which all  of the Registrable
     Securities requested to be included in such registration
     by any holders of  Registrable Securities shall have
     been registered pursuant to this section 2.1. 
     Underwriting discounts and commissions and transfer
     taxes, if any (and, when applicable, the Registration
     Expenses) in connection with each registration requested
     under this section 2.1 shall be allocated pro rata among
     all Persons on whose behalf securities of the Company
     are included in such registration, on the basis of the
     respective amounts of the securities then being
     registered on their behalf.

                    (d)  Effective Registration Statement.  A
     registration requested pursuant to this section 2.1
     shall not be deemed to have been effected (i) unless a
     registration statement with respect thereto has become
     effective, provided that a registration which does not
     become effective after the Company has filed a
     registration statement with respect thereto solely by
     reason of the refusal to proceed of the Initiating
     Holders (other than a refusal to proceed based upon the
     advice of counsel relating to a matter with respect to
     the Company) shall be deemed to have been effected by
     the Company at the request of such Initiating Holders
     unless the Initiating Holders shall have elected to pay
     all Registration Expenses in connection with such
     registration, (ii) if, after it has become effective,
     such registration becomes subject to any stop order,
     injunction or other order or requirement of the
     Commission or other governmental agency or court for any
     reason, other than by reason of some act or omission by
     any Initiating Holder, or (iii) the conditions to
     closing specified in the purchase agreement or
     underwriting agreement entered into in connection with
     such registration are not satisfied, other than by
     reason of some act or omission by such Initiating
     Holders.

                    (e)  Selection of Underwriters.  If a
     requested registration pursuant to this section 2.1
     involves an underwritten offering, the managing or lead
     underwriter or underwriters thereof shall be selected by
     the holders of at least a majority (by number of shares)
     of the Registrable Securities as to which registration
     has been requested.

                    (f)  Priority in Requested Registrations. 
     If a requested registration pursuant to this section 2.1
     involves an underwritten offering, and the managing
     underwriter shall advise the Company in writing (with a
     copy to each holder of Registrable Securities requesting
     registration) that, in its opinion, the number of
     securities requested to be included in such registration
     (including securities of the Company which are not
     Registrable Securities) exceeds the number which can be
     sold in such offering within a price range acceptable to
     the holders of a majority of the Registrable Securities
     so requested to be included, the Company will include in
     such registration, to the extent of the number which the
     Company is so advised can be sold in such offering,
     first, Registrable Securities requested to be included
     in such registration by the holder or holders of
     Registrable Securities, pro rata among such holders
     requesting such registration on the basis of the number
     of such securities requested to be included by such
     holders and (ii) second, securities the Company proposes
     to sell and other securities of the Company included in
     such registration by the holders thereof.

                    2.2  Incidental Registration.

                    (a)  Right to Include Registrable
     Securities.  If the Company at any time proposes to
     register any of its securities under the Securities Act
     (other than by a registration on Form S-4 or on Form S-
     8, or any successor or similar forms), whether or not
     for sale for its own account, it will each such time
     give prompt written notice to all holders of Registrable
     Securities of its intention to do so and of such
     holders' rights under this section 2.2.  Upon the
     written request of any such holder made within 30 days
     after the receipt of any such notice (which request
     shall specify the Registrable Securities intended to be
     disposed of by such holder and the intended method of
     disposition thereof), the Company will, subject to the
     terms of this Agreement, use its best efforts to effect
     the registration under the Securities Act of all
     Registrable Securities which the Company has been so
     requested to register by the holders thereof, to the
     extent requisite to permit the disposition (in
     accordance with the intended methods thereof as
     aforesaid) of the Registrable Securities so to be
     registered, by inclusion of such Registrable Securities
     in the registration statement which covers the
     securities which the Company proposes to register,
     provided that if, at any time after giving written
     notice of its intention to register any securities and
     prior to the effective date of the registration
     statement filed in connection with such registration,
     the Company shall determine for any reason either not to
     register or to delay registration of such securities,
     the Company may, at its election, give written notice of
     such determination to each holder of Registrable
     Securities and, thereupon, (i) in the case of a
     determination not to register, shall be relieved of its
     obligation to register any Registrable Securities in
     connection with such registration (but not from its
     obligation to pay the Registration Expenses in
     connection therewith), without prejudice, however, to
     the rights of any holder or holders of Registrable
     Securities entitled to do so to request that such
     registration be effected as a registration under section
     2.1, and (ii) in the case of a determination to delay
     registering, shall be permitted to delay registering any
     Registrable Securities, for the same period as the delay
     in registering such other securities.  No registration
     effected under this section 2.2 shall relieve the
     Company of its obligation to effect any registration
     upon request under section 2.1, nor shall any such
     registration hereunder be deemed to have been effected
     pursuant to section 2.1.  The Company will pay all
     Registration Expenses in connection with each
     registration of Registrable Securities requested
     pursuant to this section 2.2.

                    (b)  Priority in Incidental
     Registrations.  If (i) a registration pursuant to this
     section 2.2 involves an underwritten offering of the
     securities so being registered, whether or not for sale
     for the account of the Company, to be distributed (on a
     firm commitment basis) by or through one or more
     underwriters of recognized standing under underwriting
          terms appropriate for such a transaction, (ii) the
     Registrable Securities so requested to be registered for
     sale for the account of holders of Registrable
     Securities are not also to be included in such
     underwritten offering (either because the Company has
     not been requested so to include such Registrable
     Securities pursuant to section 2.4(b) or, if requested
     to do so, is not obligated to do so under section
     2.4(b), and (iii) the managing underwriter of such
     underwritten offering shall inform the Company and
     holders of the Registrable Securities requesting such
     registration by letter of its belief that the number of
     securities requested to be included in such registration
     exceeds the number which can be sold in (or during the
     time of) such offering, then the Company will include in
     such registration, to the extent of the number which the
     Company is so advised can be sold in (or during the time
     of) such offering, (a) first, securities of the Company
     to be sold for its own account and (b) second ,
     Registrable Securities and other securities of the
     Company requested to be included in such registration
     pro rata on the basis of the number of shares of such
     securities so proposed to be sold and so requested to be
     included.

               2.3  Registration Procedures.  If and whenever
     (a) the Company is required to use its best efforts to
     effect the registration of any Registrable Securities
     under the Securities Act as provided in sections 2.1 and
     2.2 or (b) there is a Requesting Holder in connection
     with any other proposed registration by the Company
     under the Securities Act, the Company shall, as
     expeditiously as possible:

                         (i)  prepare and (in the case of a
          registration pursuant to section 2.1, such filing
          to be made within 60 days after the initial request
          of one or more Initiating Holders of Registrable
          Securities or in any event as soon thereafter as
          possible) file with the Commission the requisite
          registration statement to effect such registration
          (including such audited financial statements as may
          be required by the Securities Act or the rules and
          regulations promulgated thereunder) and thereafter
          use its best efforts to cause such registration
          statement to become and remain effective, provided
          however that the Company may discontinue any
          registration of its securities which are not
          Registrable Securities (and, under the
          circumstances specified in section 2.2(a), its
          securities which are Registrable Securities) at any
          time prior to the effective date of the
          registration statement relating thereto, provided
          further that before filing such registration
          statement or any amendments thereto, the Company
          will furnish to the counsel selected by the holders
          of Registrable Securities which are to be included
          in such registration copies of all such documents
          proposed to be filed, which documents will be
          subject to the review of such counsel;

                         (ii)  prepare and file with the
          Commission such amendments and supplements to such
               registration statement and the prospectus used in
          connection therewith as may be necessary to keep
          such registration statement effective and to comply
          with the provisions of the Securities Act with
          respect to the disposition of all securities
          covered by such registration statement until the
          earlier of such time as all of such securities have
          been disposed of in accordance with the intended
          methods of disposition by the seller or sellers
          thereof set forth in such registration statement or
          (i) in the case of a registration pursuant to
          section 2.1, the expiration of 180 days after such
          registration statement becomes effective, or (ii)
          in the case of a registration pursuant to section
          2.2, the expiration of 90 days after such
          registration statement becomes effective;

                         (iii)  furnish to each seller of
          Registrable Securities covered by such registration
          statement, and each Requesting Holder and each
          underwriter, if any, of the securities being sold
          by such seller, such number of conformed copies of
          such registration statement and of each such
          amendment and supplement thereto (in each case
          including all exhibits), such number of copies of
          the prospectus contained in such registration
          statement (including each preliminary prospectus
          and any summary prospectus) and any other
          prospectus filed under Rule 424 under the
          Securities Act, in conformity with the requirements
          of the Securities Act, and such other documents, as
          such seller and underwriter, if any, may reasonably
          request in order to facilitate the public sale or
          other disposition of the Registrable Securities
          owned by such seller;

                         (iv)  use its best efforts to
          register or qualify all Registrable Securities and
          other securities covered by such registration
          statement under such other securities laws or blue
          sky laws of such jurisdictions as any seller
          thereof, any underwriter of the securities being
          sold by such seller and any Requesting Holder shall
          reasonably request, to keep such registrations or
          qualifications in effect for so long as such
          registration statement remains in effect, and take
          any other action which may be reasonably necessary
          or advisable to enable such seller and underwriter
          to consummate the disposition in such jurisdictions
          of the securities owned by such seller, except that
          the Company shall not for any such purpose be
          required to qualify generally to do business as a
          foreign corporation in any jurisdiction wherein it
          would not but for the requirements of this
          subdivision (iv) be obligated to be so qualified 
          or to consent to general service of process in any
          such jurisdiction;

                         (v)  use its best efforts to cause
          all Registrable Securities covered by such
          registration statement to be registered with or
          approved by such other governmental agencies or
          authorities as may be necessary to enable the
               seller or sellers thereof to consummate the
          disposition of such Registrable Securities;

                         (vi)  furnish to each seller of
          Registrable Securities and each Requesting Holder a
          signed counterpart, addressed to such seller, such
          Requesting Holder and the underwriters, if any, of:

     (x)  an opinion of counsel for the Company, dated the
     effective date of such registration statement (or, if
     such registration includes an underwritten public
     offering, an opinion dated the date of the closing under
     the underwriting agreement), reasonably satisfactory in
     form and substance to such seller, and 

     (y)  a "comfort" letter (or, in the case of any such
     Person which does not satisfy the conditions for receipt
     of a "comfort" letter specified in Statement on Auditing
     Standards No. 72, an "agreed upon procedures" letter),
     dated the effective date of such registration statement
     (and, if such registration includes an underwritten
     public offering, a letter of like kind dated the date of
     the closing under the underwriting agreement), signed by
     the independent public accountants who have certified
     the Company's financial statements included in such
     registration statement,

          covering substantially the same matters with
          respect to such registration statement (and the
          prospectus included therein) and, in the case of
          the accountants' letter, with respect to events
          subsequent to the date of such financial
          statements, as are customarily covered in opinions
          of issuer's counsel and in accountants' letters
          delivered to the underwriters in underwritten
          public offerings of securities (with, in the case
          of an "agreed upon procedures" letter, such
          modifications or deletions as may be required under
          Statement on Auditing Standards No. 35) and, in the
          case of the accountants' letter, such other
          financial matters, and, in the case of the legal
          opinion, such other legal matters, as such seller
          or such Requesting Holder (or the underwriters, if
          any) may reasonably request;

                         (vii)  notify the holders of
          Registrable Securities and the managing underwriter
          or underwriters, if any, promptly and confirm such
          advice in writing promptly thereafter:

                    (v)  when the registration statement, the
     prospectus or any prospectus supplement related thereto
     or post-effective amendment to the registration
     statement has been filed, and, with respect to the
     registration statement or any post-effective amendment
     thereto, when the same has become effective;

                    (w)  of any request by the Commission for
     amendments or supplements to the registration statement
     or the prospectus or for additional information;

                         (x)  of the issuance by the Commission of
     any stop order suspending the effectiveness of the
     registration statement or the initiation of any
     proceedings by any Person for that purpose;

                    (y)  if at any time the representations
     and warranties of the Company made as contemplated by
     section 2.4 below cease to be true and correct;

                    (z)  of the receipt by the Company of any
     notification with respect to the suspension of the
     qualification of any Registrable Securities for sale
     under the securities or blue sky laws of any
     jurisdiction or the initiation or threat of any
     proceeding for such purpose; and

                         (viii)  notify each seller of
          Registrable Securities covered by such registration
          statement and each Requesting Holder, at any time
          when a prospectus relating thereto is required to
          be delivered under the Securities Act, upon the
          Company's discovery that, or upon the happening of
          any event as a result of which, the prospectus
          included in such registration statement, as then in
          effect, includes an untrue statement of a material
          fact or omits to state any material fact required
          to be stated therein or necessary to make the
          statements therein not misleading in the light of
          the circumstances then existing, and at the request
          of any such seller or Requesting Holder promptly
          prepare and furnish to such seller or Requesting
          Holder and each underwriter, if any, a reasonable
          number of copies of a supplement to or an amendment
          of such prospectus as may be necessary so that, as
          thereafter delivered to the purchasers of such
          securities, such prospectus shall not include an
          untrue statement of a material fact or omit to
          state a material fact required to be stated therein
          or necessary to make the statements therein not
          misleading in the light of the circumstances then
          existing;

                         (ix)  make every reasonable effort
          to obtain the withdrawal of any order suspending
          the effectiveness of the registration statement at
          the earliest possible moment;

                         (x)  otherwise use its best efforts
          to comply with all applicable rules and regulations
          of the Commission, and make available to its
          security holders, as soon as reasonably
          practicable, an earnings statement covering the
          period of at least twelve months, but not more than
          eighteen months, beginning with the first day of
          the Company's first full calendar month after the
          effective date of such registration statement,
          which earnings statement shall satisfy the
          provisions of Section 11(a) of the Securities Act
          and Rule 158 thereunder, and will furnish to each
          such seller and each Requesting Holder at least
          five business days prior to the filing thereof a
          copy of any amendment or supplement to such
          registration statement or prospectus and shall not
               file any thereof to which any such seller or any
          Requesting Holder shall have reasonably objected on
          the grounds that such amendment or supplement does
          not comply in all material respects with the
          requirements of the Securities Act or of the rules
          or regulations thereunder;

                         (xi)  provide and cause to be
          maintained a transfer agent and registrar for all
          Registrable Securities covered by such registration
          statement from and after a date not later than the
          effective date of such registration statement;

                         (xii)  enter into such agreements
          and take such other actions as sellers of such
          Registrable Securities holding 51% of the shares so
          to be sold shall reasonably request in order to
          expedite or facilitate the disposition of such
          Registrable Securities;

                         (xiii)  use its best efforts to list
          all Registrable Securities covered by such
          registration statement on any securities exchange
          on which any of the securities of the same class as
          the Registrable Securities are then listed;

                         (xiv)  use its best efforts to
          provide a CUSIP number for the Registrable
          Securities, not later than the effective date of
          the registration statement.

     The Company may require each seller of Registrable
     Securities as to which any registration is being
     effected to furnish the Company such information
     regarding such seller and the distribution of such
     securities as the Company may from time to time
     reasonably request in writing.

               The Company will not file any registration
     statement or amendment thereto or any prospectus or any
     supplement thereto (including such documents
     incorporated by reference and proposed to be filed after
     the initial filing of the registration statement) to
     which the holders of at least a majority of the
     Registrable Securities covered by such registration
     statement or the underwriter or underwriters, if any,
     shall reasonably object, provided that the Company may
     file such document in a form required by law or upon the
     advice of its counsel.

               Each holder of Registrable Securities agrees
     that, upon receipt of any notice from the Company of the
     occurrence of any event of the kind described in
     subdivision (viii) of this section 2.3, such holder will
     forthwith discontinue such holder's disposition of
     Registrable Securities pursuant to the registration
     statement relating to such Registrable Securities until
     such holder's receipt of the copies of the supplemented
     or amended prospectus contemplated by subdivision (viii)
     of this section 2.3 and, if so directed by the Company,
     will deliver to the Company (at the Company's expense)
     all copies, other than permanent file copies, then in
     such holder's possession, of the prospectus relating to
          such Registrable Securities current at the time of
     receipt of such notice.  In the event the Company shall
     give any such notice, the period mentioned in paragraph
     (ii) of this section 2.3 shall be extended by the length
     of the period from and including the date when each
     seller of any Registrable Securities covered by such
     registration statement shall have received such notice
     to the date on which each such seller has received the
     copies of the supplemented or amended prospectus
     contemplated by paragraph (viii) of this section 2.3.

               If any such registration statement refers to
     any holder of Registrable Securities by name or
     otherwise as the holder of any securities of the
     Company, then such holder shall have the right to
     require (i) the insertion therein of language, in form
     and substance satisfactory to such holder, to the effect
     that the holding by such holder of such securities is
     not to be construed as a recommendation by such holder
     of the investment quality of the Company's securities
     covered thereby and that such holding does not imply
     that such holder will assist in meeting any future
     financial requirements of the Company, or (ii) in the
     event that such reference to such holder by name or
     otherwise is not required by the Securities Act or any
     similar federal statute then in force, the deletion of
     the reference to such holder.  

               2.4  Underwritten Offerings. 

                    (a)  Requested Underwritten Offerings. 
     If requested by the underwriters for any underwritten
     offering by holders of Registrable Securities pursuant
     to a registration requested under section 2.1, the
     Company will enter into an underwriting agreement with
     such underwriters for such offering, such agreement to
     contain such representations and warranties by the
     Company and such other terms as are generally prevailing
     in agreements of this type, including, without
     limitation, indemnities to the effect and to the extent
     provided in section 2.7.  The holders of the Registrable
     Securities will cooperate with the Company in the
     negotiation of the underwriting agreement and will give
     consideration to the reasonable suggestions of the
     Company regarding the form thereof, provided that
     nothing herein contained shall diminish the foregoing
     obligations of the Company.  The holders of Registrable
     Securities to be distributed by such underwriters shall
     be parties to such underwriting agreement and may, at
     their option, require that any or all of the
     representations and warranties by, and the other
     agreements on the part of, the Company to and for the
     benefit of such underwriters shall also be made to and
     for the benefit of such holders of Registrable
     Securities and that any or all of the conditions
     precedent to the obligations of such underwriters under
     such underwriting agreement be conditions precedent to
     the obligations of such holders of Registrable
     Securities.  Any such holder of Registrable Securities
     shall not be required to make any representations or
     warranties to or agreements with the Company or the
     underwriters other than representations and warranties
     or agreements regarding such holder, such holder's
          Registrable Securities and such holder's intended method
     of distribution.

                    (b)  Incidental Underwritten Offerings. 
     If the Company at any time proposes to register any of
     its securities under the Securities Act as contemplated
     by section 2.2 and such securities are to be distributed
     by or through one or more underwriters, the Company
     will, if requested by any holder of Registrable
     Securities as provided in section 2.2 and subject to the
     provisions of section 2.2(b), use its best efforts to
     arrange for such underwriters to include all the
     Registrable Securities to be offered and sold by such
     holder among the securities to be distributed by such
     underwriters, provided that if the managing underwriter
     of such underwritten offering shall inform the holders
     of the Registrable Securities requesting such
     registration and the holders of any other shares of
     securities which shall have exercised, in respect of
     such underwritten offering, registration rights
     comparable to the rights under section 2.2 by letter of
     its belief that inclusion in such underwritten
     distribution of all or a specified number of such
     Registrable Securities or of such other shares of
     securities so requested to be included would interfere
     with the successful marketing of the securities (other
     than such Registrable Securities and other shares of
     securities so requested to be included) by the
     underwriters (such writing to state the basis of such
     belief and the approximate number of such Registrable
     Securities and shares of other securities so requested
     to be included which may be included in such
     underwritten offering without such effect), then the
     Company may, upon written notice to all holders of such
     Registrable Securities and of such other shares of
     securities so requested to be included, exclude pro rata
     from such underwritten offering (if and to the extent
     stated by such managing underwriter to be necessary to
     eliminate such effect) the number of such Registrable
     Securities and shares of such other securities so
     requested to be included, the registration of which
     shall have been requested by each holder of Registrable
     Securities and by the holders of such other securities,
     so that the resultant aggregate number of such
     Registrable Securities and of such other shares of
     securities so requested to be included which are
     included in such underwritten offering shall be equal to
     the approximate number of shares stated in such managing
     underwriter's letter.  The holders of Registrable
     Securities to be distributed by such underwriters shall
     be parties to the underwriting agreement between the
     Company and such underwriters and may, at their option,
     require that any or all of the representations and
     warranties by, and the other agreements on the part of,
     the Company to and for the benefit of such underwriters
     shall also be made to and for the benefit of such
     holders of Registrable Securities and that any or all of
     the conditions precedent to the obligations of such
     underwriters under such underwriting agreement be
     conditions precedent to the obligations of such holders
     of Registrable Securities.  Any such holder of
     Registrable Securities shall not be required to make any
     representations or warranties to or agreements with the
          Company or the underwriters other than representations,
     warranties or agreements regarding such holder, such
     holder's Registrable Securities, such holder's intended
     method of distribution and any other representation
     required by law.

                    (c)  Holdback Agreements.

                         (i)  Each holder of Registrable
          Securities agrees by acquisition of such
          Registrable Securities, if so required by the
          managing underwriter, not to sell, make any short
          sale of, loan, grant any option for the purchase
          of, effect any public sale or distribution of or
          otherwise dispose of any equity securities of the
          Company, during the seven days prior to and the 90
          days after any underwritten registration pursuant
          to section 2.1 or 2.2 has become effective, except
          as part of such underwritten registration. 
          Notwithstanding the foregoing sentence, each holder
          of Registrable Securities subject to the foregoing
          sentence shall be entitled to sell during the
          foregoing period securities in a private sale.

                         (ii)  The Company agrees (x) not to
          sell, make any short sale of, loan, grant any
          option for the purchase of, effect any public sale
          or distribution of or otherwise dispose of its
          equity securities or securities convertible into or
          exchangeable or exercisable for any of such
          securities during the seven days prior to and the
          90 days after any underwritten registration
          pursuant to section 2.1 or 2.2 has become
          effective, except as part of such underwritten
          registration or except in connection with a stock
          option plan, stock purchase plan, managing
          directors' plan, savings or similar plan, or an
          acquisition of a business, merger or exchange of
          stock for stock, and (y) to cause each holder of
          its equity securities or any securities convertible
          into or exchangeable or exercisable for any of such
          securities, in each case purchased from the Company
          at any time after the date of this Agreement (other
          than in a public offering) to agree not to sell,
          make any short sale of, loan, grant any option for
          the purchase of, effect any public sale or
          distribution of or otherwise dispose of such
          securities during such period except as part of
          such underwritten registration.

                    (d)  Participation in Underwritten
     Offerings.  No Person may participate in any
     underwritten offering hereunder unless such Person (i)
     agrees to sell such Person's securities on the basis
     provided in any underwriting arrangements approved,
     subject to the terms and conditions hereof, by the
     Company and the holders of a majority of Registrable
     Securities to be included in such underwritten offering
     and (ii) completes and executes all questionnaires,
     indemnities, underwriting agreements and other documents
     (other than powers of attorney) required under the terms
     of such underwriting arrangements.  Notwithstanding the
     foregoing, no underwriting agreement (or other agreement
          in connection with such offering) shall require any
     holder of Registrable Securities to make any
     representations or warranties to or agreements with the
     Company or the underwriters other than representations
     and warranties or agreements regarding such holder, such
     holder's Registrable Securities,  such holder's intended
     method of distribution and any other representation
     required by law.

               2.5  Preparation; Reasonable Investigation. 
     In connection with the preparation and filing of each
     registration statement under the Securities Act pursuant
     to this Agreement, the Company will give the holders of
     Registrable Securities registered under such
     registration statement, their underwriters, if any, each
     Requesting Holder and their respective counsel and
     accountants, the opportunity to participate in the
     preparation of such registration statement, each
     prospectus included therein or filed with the
     Commission, and each amendment thereof or supplement
     thereto, and will give each of them such access to its
     books and records and such opportunities to discuss the
     business of the Company with its officers and the
     independent public accountants who have certified its
     financial statements as shall be necessary, in the
     opinion of such holders' and such underwriters'
     respective counsel, to conduct a reasonable
     investigation within the meaning of the Securities Act.

               2.6  Rights of Requesting Holders.  The
     Company will not file any registration statement under
     the Securities Act (other than by a registration on Form
     S-8), unless it shall first have given to each holder of
     Registrable Securities at the time outstanding (other
     than any such Person who acquired all such securities
     held by such Person in a public offering registered
     under the Securities Act or as the direct or indirect
     transferee of shares initially issued in such an
     offering), at least 30 days prior written notice
     thereof.  Any such Person who shall so request within 30
     days after such notice (a "Requesting Holder") shall
     have the rights of a Requesting Holder provided in
     sections 2.3, 2.5 and 2.7.  In addition, if any such
     registration statement refers to any Requesting Holder
     by name or otherwise as the holder of any securities of
     the Company, then such holder shall have the right to
     require (a) the insertion therein of language, in form
     and substance satisfactory to such holder, to the effect
     that the holding by such holder of such securities does
     not necessarily make such holder a "controlling person"
     of the Company within the meaning of the Securities Act
     and is not to be construed as a recommendation by such
     holder of the investment quality of the Company's debt
     or equity securities covered thereby and that such
     holding does not imply that such holder will assist in
     meeting any future financial requirements of the
     Company, or (b) in the event that such reference to such
     holder by name or otherwise is not required by the
     Securities Act or any rules and regulations promulgated
     thereunder, the deletion of the reference to such
     holder.

                    2.7  Indemnification.  

                    (a)  Indemnification by the Company.  In
     the event of any registration of any securities of the
     Company under the Securities Act, the Company will, and
     hereby does agree to, indemnify and hold harmless (i) in
     the case of any registration statement filed pursuant to
     section 2.1 or 2.2, the holder of any Registrable
     Securities covered by such registration statement, any
     partner or affiliate of such holder, and their
     respective directors, officers, stockholders, employees
     and agents, each other Person who participates as an
     underwriter in the offering or sale of such securities
     and each other Person, if any, who controls such holder
     or any such underwriter within the meaning of the
     Securities Act, and (ii) in the case of any,
     registration statement of the Company, any Requesting
     Holder, any partner or affiliate of such Requesting
     Holder, each other Person, if any, who controls such
     Requesting Holder within the meaning of the Securities
     Act, and their respective directors, officers,
     stockholders, employees and agents, against any losses,
     claims, damages or liabilities, joint or several, to
     which such holder or Requesting Holder or any such
     partner, affiliate, director, officer, stockholder,
     employee, agent or underwriter or controlling person may
     become subject under the Securities Act or otherwise,
     insofar as such losses, claims, damages or liabilities
     (or actions or proceedings, whether commenced or
     threatened, in respect thereof) arise out of or are
     based upon any untrue statement or alleged untrue
     statement of any material fact contained in any
     registration statement under which such securities were
     registered under the Securities Act, any preliminary
     prospectus, final prospectus or summary prospectus
     contained therein, or any amendment or supplement
     thereto, or any omission or alleged omission to state
     therein a material fact required to be stated therein or
     necessary to make the statements therein not misleading,
     and the Company will reimburse such holder, such
     Requesting Holder and each such partner, affiliate,
     director, officer, stockholder, employee, agent,
     underwriter and controlling person for any legal or any
     other expenses reasonably incurred by them in connection
     with investigating or defending any such loss, claim,
     liability, action or proceeding, provided that the
     Company shall not be liable in any such case to the
     extent that any such loss, claim, damage, liability (or
     action or proceeding in respect thereof) or expense
     arises out of or is based upon an untrue statement or
     alleged untrue statement or omission or alleged omission
     made in such registration statement, any such
     preliminary prospectus, final prospectus, summary
     prospectus, amendment or supplement in reliance upon and
     in conformity with written information furnished to the
     Company through an instrument duly executed by such
     holder or Requesting Holder, as the case may be,
     specifically stating that it is for use in the
     preparation thereof and, provided further that the
     Company shall not be liable to any Person who
     participates as an underwriter in the offering or sale
     of Registrable Securities or to any other Person, if
     any, who controls such underwriter within the meaning of
          the Securities Act, in any such case to the extent that
     any such loss, claim, damage, liability (or action or
     proceeding in respect thereof) or expense arises out of
     such Person's failure to send or give a copy of the
     final prospectus, as the same may be then supplemented
     or amended, within the time required by the Securities
     Act to the Person asserting the existence of an untrue
     statement or alleged untrue statement or omission or
     alleged omission at or prior to the written confirmation
     of the sale of Registrable Securities to such Person if
     such statement or omission was corrected in such final
     prospectus.  Such indemnity shall remain in full force
     and effect regardless of any investigation made by or on
     behalf of such holder or such Requesting Holder or any
     such director, officer, underwriter or controlling
     person and shall survive the transfer of such securities
     by such holder.

                    (b)  Indemnification by the Sellers.  The
     Company may require, as a condition to including any
     Registrable Securities in any registration statement
     filed pursuant to section 2.3, that the Company shall
     have received an undertaking satisfactory to it from the
     prospective seller of such Registrable Securities, to
     indemnify and hold harmless (in the same manner and to
     the same extent as set forth in subdivision (a) of this
     section 2.7) the Company, each director of the Company,
     each officer of the Company and each other person, if
     any, who controls the Company within the meaning of the
     Securities Act, with respect to any statement or alleged
     statement in or omission or alleged omission from such
     registration statement, any preliminary prospectus,
     final prospectus or summary prospectus contained
     therein, or any amendment or supplement thereto, if such
     statement or alleged statement or omission or alleged
     omission was made in reliance upon and in conformity
     with written information furnished to the Company
     through an instrument duly executed by such seller
     specifically stating that it is for use in the
     preparation of such registration statement, preliminary
     prospectus, final prospectus, summary prospectus,
     amendment or supplement.  Any such indemnity shall
     remain in full force and effect, regardless of any
     investigation made by or on behalf of the Company or any
     such director, officer or controlling person and shall
     survive the transfer of such securities by such seller.

                    (c)  Notices of Claims, etc.   Promptly
     after receipt by an indemnified party of notice of the
     commencement of any action or proceeding involving a
     claim referred to in the preceding subdivisions of this
     section 2.7, such indemnified party will, if a claim in
     respect thereof is to be made against an indemnifying
     party, give written notice to the latter of the
     commencement of such action, provided that the failure
     of any indemnified party to give notice as provided
     herein shall  not relieve the indemnifying party of its
     obligations under the preceding subdivisions of this
     section 2.7, except to the extent that the indemnifying
     party is actually prejudiced by such failure to give
     notice.  In case any such action is brought against an
     indemnified party, unless in such indemnified party's
     reasonable judgment a conflict of interest between such
          indemnified and indemnifying parties may exist in
     respect of such claim, the indemnifying party shall be
     entitled to participate in and to assume the defense
     thereof, jointly with any other indemnifying party
     similarly notified, to the extent that the indemnifying
     party may wish, with counsel reasonably satisfactory to
     such indemnified party, and after notice from the
     indemnifying party to such indemnified party of its
     election so to assume the defense thereof, the
     indemnifying party shall not be liable to such
     indemnified party for any legal or other expenses
     subsequently incurred by the latter in connection with
     the defense thereof other than reasonable costs of
     investigation.  No indemnifying party shall, without the
     consent of the indemnified party, consent to entry of
     any judgment or enter into any settlement of any such
     action which does not include as an unconditional term
     thereof the giving by the claimant or plaintiff to such
     indemnified party of a release from all liability in
     respect to such claim or litigation.  No indemnified
     party shall consent to entry of any judgment or enter
     into any settlement of any such action the defense of
     which has been assumed by an indemnifying party without
     the consent of such indemnifying party.

                    (d)  Other Indemnification. 
     Indemnification similar to that specified in the
     preceding subdivisions of this section 2.7 (with
     appropriate modifications) shall be given by the Company
     and each seller of Registrable Securities with respect
     to any required registration or other qualification of
     securities under any Federal or state law or regulation
     of any governmental authority, other than the Securities
     Act.

                    (e)  Indemnification Payments.  The
     indemnification required by this section 2.7 shall be
     made by periodic payments of the amount thereof during
     the course of the investigation or defense, as and when
     bills are received or expense, loss, damage or liability
     is incurred.

                    (f)  Contribution.  If the
     indemnification provided for in the preceding
     subdivisions of this section 2.7 is unavailable to an
     indemnified party in respect of any expense, loss,
     claim, damage or liability referred to therein, then
     each indemnifying party, in lieu of indemnifying such
     indemnified party, shall contribute to the amount paid
     or payable by such indemnified party as a result of such
     expense, loss, claim, damage or liability (i) in such
     proportion as is appropriate to reflect the relative
     benefits received by the Company on the one hand and the
     holder or underwriter, as the case may be, on the other
     from the distribution of the Registrable Securities or
     (ii) if the allocation provided by clause (i) above is
     not permitted by applicable law, in such proportion as
     is appropriate to reflect not only the relative benefits
     referred to in clause (i) above but also the relative
     fault of the Company on the one hand and of the holder
     or underwriter, as the case may be, on the other in
     connection with the statements or omissions which
     resulted in such expense, loss, damage or liability, as
          well as any other relevant equitable considerations. 
     The relative benefits received by the Company on the one
     hand and the holder or underwriter, as the case may be,
     on the other in connection with the distribution of the
     Registrable Securities shall be deemed to be in the same
     proportion as the total net proceeds received by the
     Company from the initial sale of the Registrable
     Securities by the Company to the purchasers pursuant to
     the Securities Purchase Agreement bear to the gain, if
     any, realized by the selling holder or the underwriting
     discounts and commissions received by the underwriter,
     as the case may be.  The relative fault of the Company
     on the one hand and of the holder or underwriter, as the
     case may be, on the other shall be determined by
     reference to, among other things, whether the untrue or
     alleged untrue statement of a material fact or omission
     to state a material fact relates to information supplied
     by the Company, by the holder or by the underwriter and
     the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such
     statement or omission, provided that the foregoing
     contribution agreement shall not inure to the benefit of
     any indemnified party if indemnification would be
     unavailable to such indemnified party by reason of the
     provisions contained in the first sentence of
     subdivision (a) of this section 2.7, and in no event
     shall the obligation of any indemnifying party to
     contribute under this subdivision (f) exceed the amount
     that such indemnifying party would have been obligated
     to pay by way of indemnification if the indemnification
     provided for under subdivisions (a) or (b) of this
     section 2.7 had been available under the circumstances.

               The Company and the holders of Registrable
     Securities agree that it would not be just and equitable
     if contribution pursuant to this subdivision (f) were
     determined by pro rata allocation (even if the holders,
     Requesting Holders and any underwriters were treated as
     one entity for such purpose) or by any other method of
     allocation that does not take account of the equitable
     considerations referred to in the immediately preceding
     paragraph.  The amount paid or payable by an indemnified
     party as a result of the losses, claims, damages and
     liabilities referred to in the immediately preceding
     paragraph shall be deemed to include, subject to the
     limitations set forth in the preceding sentence and
     subdivision (c) of this section 2.7, any legal or other
     expenses reasonably incurred by such indemnified party
     in connection with investigating or defending any such
     action or claim.

               Notwithstanding the provisions of this
     subdivision (f), no holder of Registrable Securities or
     underwriter shall be required to contribute any amount
     in excess of the amount by which (i) in the case of any
     such holder, the net proceeds received by such holder
     from the sale of Registrable Securities or (ii) in the
     case of an underwriter, the total price at which the
     Registrable Securities purchased by it and distributed
     to the public were offered to the public exceeds, in any
     such case, the amount of any damages that such holder or
     underwriter has otherwise been required to pay by reason
     of such untrue or alleged untrue statement or omission. 
          No Person guilty of fraudulent misrepresentation (within
     the meaning of Section 11(f) of the Securities Act)
     shall be entitled to contribution from any person who
     was not guilty of such fraudulent misrepresentation.

               2.8  Adjustments Affecting Registrable
     Securities.  The Company will not effect or permit to
     occur any combination or subdivision of shares which
     would adversely affect the ability of the holders of
     Registrable Securities to include such Registrable
     Securities in any registration of its securities
     contemplated by this section 2 or the marketability of
     such Registrable Securities under any such registration.

               1.2.1.  The holder of each issued and
     outstanding share of Series E Preferred Stock and Series
     H Preferred Stock shall be entitled to receive, out of
     the funds of the Company legally available for such
     purpose, when, as and if declared by the Board of
     Directors of the Company, before any dividend shall be
     declared, paid or set aside, or any other distribution
     shall be declared or made, upon the Common Stock or any
     other class or series of stock of the Company (other than
     the Series F Preferred Stock and the Series G Preferred
     Stock), dividends in cash at a dividend rate of seven
     percent (7.0%) per annum of the Stated Value per share of
     Series E Preferred Stock and Series H Preferred Stock,
     calculated on a daily basis, for each Dividend Period or
     portion thereof during which such Series E Preferred
     Stock and Series H Preferred Stock are outstanding. 
     Notwithstanding the foregoing, the Company may declare
     and pay dividends in the form of Common Stock (with
     fractional shares to be paid in cash) pursuant to the
     terms of the Series D Preferred Stock.

               1.2.2.  Notwithstanding anything to the
     contrary herein provided, in the event that any portion
     of the quarterly dividend for a Dividend Period on the
     Series E Preferred Stock and the Series H Preferred Stock
     is not declared and paid in cash on any Dividend Payment
     Date, the amount of such accrued dividend which is not so
     paid shall be accumulated and shall automatically be
     added to the Stated Value of such share on such date. 
     Accumulated dividends on shares of Series E Preferred
     Stock and the Series H Preferred Stock that have
     previously been added to the Stated Value thereof
     pursuant to the terms hereof may not thereafter be paid
     in cash except upon redemption by the Company.  Unpaid
     dividends shall not bear interest but, to the extent
     accumulated and added to the Stated Value, shall continue
     to accrue dividends on a daily basis.  Accumulated
     dividends on any share of Series E Preferred Stock and
     the Series H Preferred Stock which are added to the
     Stated Value thereof pursuant to the terms hereof shall
     not be deemed to be in arrears for any purpose
     whatsoever.  Any dividends that have accrued on the
     Series E Preferred Stock and Series H Preferred Stock but
     have not yet been added to the Stated Value thereof shall
     constitute Unpaid Dividends.  Notwithstanding anything to
     the contrary herein provided, no cash dividends shall be
     paid with respect to the Common Stock, the Series A
     Preferred Stock, the Series B Preferred Stock or the
     Series D Preferred Stock at any time when there are
     Unpaid Dividends with respect to the Series E Preferred
     Stock or the Series H Preferred Stock.

               1.2.3.  Dividends payable with respect to the
     Series E Preferred Stock and the Series H Preferred Stock
     shall be calculated on the basis of a 360-day year
     consisting of twelve (12) months of thirty (30) days each
     and shall be payable on each Dividend Payment Date to the
     holders of record of the Series E Preferred Stock and the
     Series H Preferred Stock at the close of business on the
     date specified by the Board of Directors of the Company;
     provided, however, that no such record date shall be more
     than thirty (30) days nor less than ten (10) days prior
     to the respective Dividend Payment Date.  Dividends on
     shares of Series E Preferred Stock and the Series H
     Preferred Stock shall accrue from the date of original
     issue of the shares of Series C Preferred Stock in
     exchange for which such shares of Series E Preferred
     Stock and Series H Preferred Stock were issued.  Such
     dividends will accrue whether or not they have been
     declared and whether or not there are profits, surplus or
     other funds of the Company legally available for the
     payment of dividends.  The date on which the Company
     originally issues any share of Series E Preferred Stock
     or Series H Preferred Stock will be deemed to be its
     "date of original issue" regardless of the number of
     times transfer of such share is made on the stock records
     maintained by or for the Company.

               1.2.4.  All dividends paid or added to Stated
     Value, as the case may be, with respect to shares of the
     Series E Preferred Stock or Series H Preferred Stock
     shall be paid or added to Stated Value, as the case may
     be, ratably (based on the respective Stated Values plus
     Unpaid Dividends of the Series E Preferred Stock and the
     Series H Preferred Stock) with respect to such shares to
     the holders of Series E Preferred Stock and Series H
     Preferred Stock entitled thereto.

               1.2.5.  So long as any shares of the Series E
     Preferred Stock or Series H Preferred Stock are
     outstanding, the Company shall not declare, pay or set
     apart for payment any dividend or other distribution on
     any of the Company's Common Stock, or Preferred Stock
     (other than the Series F Preferred Stock, the Series G
     Preferred Stock, the Series E Preferred Stock and the
     Series H Preferred Stock) or make any payment on account
     of, or set apart for payment money for a sinking fund or
     other similar fund for the purchase, redemption or other
     retirement of, any of the Common Stock, or Preferred
     Stock (other than the Series F Preferred Stock, the
     Series G Preferred Stock, the Series E Preferred Stock
     and the Series H Preferred Stock) or any warrants,
     rights, calls or options exercisable for any of the
     Common Stock or make any distribution in respect thereof,
     either directly or indirectly, and whether in cash,
     obligations or shares of the Company or other property
     (other than distributions or dividends in stock to the
     holders of such stock), and shall not permit any Person
     directly or indirectly controlled by the Company to
     purchase or redeem any of the Common Stock or Preferred
     Stock (other than the Series F Preferred Stock, the
     Series G Preferred Stock, the Series E Preferred Stock
     and the Series H Preferred Stock) or any warrants,
     rights, calls or options exercisable for any of the
     Common Stock, unless prior to or concurrently with such
     declaration, payment, setting apart for payment, purchase
     or distribution, as the case may be, all funds then
     required for the mandatory redemption of shares of the
     Series E Preferred Stock and the Series H Preferred Stock
     pursuant to Section 1.5.2 hereof, shall have been paid or
     be paid, and all Unpaid Dividends on shares of the Series
     E Preferred Stock and the Series H Preferred Stock not
     paid in cash, shall have been paid in cash or be paid in
     cash.  Notwithstanding the foregoing, the Company may
     declare and pay cash dividends on the Common Stock
     provided that (a) the Company is not then in default with
     respect to any of its obligations to pay dividends on the
     Series E Preferred Stock and the Series H Preferred
     Stock, (b) cash dividends on Common Stock during any
     fiscal year of the Company do not exceed twenty percent
     (20%) of the after-tax earnings per share of Common Stock
     for the immediately preceding fiscal year of the Company
     and (c) all Unpaid Dividends on the Series E Preferred
     Stock and the Series H Preferred Stock shall be paid in
     cash concurrently with the payment of such cash dividend
     on the Common Stock.  Notwithstanding the foregoing, the
     Company many declare and pay dividends in the form of
     Common Stock (with fractional shares to be paid in cash)
     pursuant to the terms of the Series D Preferred Stock.
                                    
               1.3.  Rights on Liquidation, Dissolution or
     Winding-Up.

               1.3.1.  In the event of any liquidation,
     dissolution or winding-up of the Company (including,
     without limitation, a liquidation or reorganization under
     Chapter 7 or 11 of Title 11 of the United States Code, as
     amended), after payment in full of all amounts due to the
     holders of Series F Preferred Stock and Series G
     Preferred Stock, the holders of shares of the Series A
     Preferred Stock, the Series E Preferred Stock and the
     Series H Preferred Stock then issued and outstanding
     shall be entitled to be paid out of the assets of the
     Company available for distribution to its stockholders,
     before any payment shall be made to the holders of Series
     B Preferred Stock, Series D Preferred Stock, Common Stock
     or of shares of any other class or series of stock of the
     Company (other than the Series F Preferred Stock and
     Series G Preferred Stock), an amount equal to the Stated
     Value per share, plus an amount equal to any Unpaid
     Dividends to and including the date of distribution with
     respect to such shares.  If, upon any liquidation,
     dissolution or winding-up of the Company (including,
     without limitation, a liquidation or reorganization under
     Chapter 7 or 11 of Title 11 of the United States Code, as
     amended), the assets of the Company available for
     distribution to its stockholders shall, after payment in
     full of all amounts due the holders of Series F Preferred
     Stock and Series G Preferred Stock, be insufficient (a
     "Liquidation Insufficiency") to pay the holders of shares
     of the Series A Preferred Stock, the Series E Preferred
     Stock and the Series H Preferred Stock the full amounts
     to which they shall respectively be entitled, the holders
     of shares of the Series A Preferred Stock, the Series E
     Preferred Stock and the Series H Preferred Stock shall be
     entitled to receive all the assets of the Company
     available for distribution and each such holder of shares
     of the Series A Preferred Stock, the Series E Preferred
     Stock and the Series H Preferred Stock shall share in any
     distribution in the proportion which the aggregate Stated
     Values of the shares of the Series A Preferred Stock
     (plus all Unpaid Dividends thereon), the Series E
     Preferred Stock (plus all Unpaid Dividends thereon) and
     the Series H Preferred Stock (plus all Unpaid Dividends
     thereon) held by such holder of the Series A Preferred
     Stock, Series E Preferred Stock or Series H Preferred
     Stock bears to the aggregate Stated Values of all shares
     of the Series A Preferred Stock (plus all Unpaid
     Dividends thereon), Series E Preferred Stock (plus all
     Unpaid Dividends thereon) and the Series H Preferred
     Stock (plus all Unpaid Dividends thereon) then
     outstanding.  If there is no Liquidation Insufficiency
     and payment shall have been made to the holders of shares
     of the Series A Preferred Stock, Series E Preferred Stock
     and Series H Preferred Stock of the full amount to which
     they shall be entitled, then the holders of shares of the
     Series A Preferred Stock, Series E Preferred Stock and
     Series H Preferred Stock shall be entitled to receive no
     further distributions thereon and the holders of shares
     of the Series B Preferred Stock shall be entitled to
     receive an amount equal to the Stated Value (plus all
     Unpaid Dividends thereon) per share thereof.  After
     payment shall have been made to the holders of shares of
     the Series B Preferred Stock of the full amounts to which
     they shall be entitled, the holders of shares of the
     Common Stock and of shares of any other class of stock of
     the Company, if any, shall be entitled to share,
     according to their respective rights and preferences, in
     all remaining assets of the Company available for
     distribution to its stockholders.

               1.4.  Voting Power.

               1.4.1.  Except as expressly provided herein in
     Section 1.4.7 or as required by law, any holder of Series
     E Preferred Stock that is a BHCA Holder shall have no
     voting rights.  Except as otherwise expressly provided
     herein or as required by law, (i) each holder of Series E
     Preferred Stock that is not a BHCA Holder shall be
     entitled to vote on all matters as to which stockholders
     of the Company are entitled to vote, and (ii) each holder
     of Series E Preferred Stock (other than BCHA Holders)
     shall be entitled to cast a number of votes equal to the
     greatest number of whole shares of Common Stock into
     which such holder's shares of Series E Preferred Stock
     could be converted, pursuant to the provisions of Section
     1.6 hereof, at the record date for the determination of
     stockholders entitled to vote on such matter or, if no
     such record date is established, at the date such vote is
     taken or any written consent of stockholders is
     solicited.  Except as otherwise expressly provided herein
     or as required by law, the holders of shares of Series B
     Preferred Stock, Series D Preferred Stock, Series E
     Preferred Stock (other than BHCA Holders), Series F
     Preferred Stock, Series G Preferred Stock (other than
     BHCA Holders), Series H Preferred Stock and Common Stock
     shall be entitled to vote together as a class with
     respect to all matters as to which such stockholders of
     the Company are entitled to vote.

               1.4.2.  The holders of Series E Preferred Stock
     (other than BHCA Holders) and Series H Preferred Stock
     shall have the right, voting together separately as a
     single class, to elect two (2) directors to the Board of
     Directors of the Company, which, unless increased
     pursuant to the Special Voting Rights, shall be composed
     of no more than ten (10) directors.

               1.4.3.  In the event that at any time there
     shall occur a Two-Dividend Default, then immediately upon
     the happening of such Two-Dividend Default and until such
     Two-Dividend Default and all defaults in the payment of
     quarterly dividends on the Series E Preferred Stock and
     Series H Preferred Stock subsequent to and occurring
     while such Two-Dividend Default exists shall be cured,
     the number of directors constituting the Board of
     Directors of the Company shall, without further action,
     be increased by two and the holders of Series E Preferred
     Stock (other than BHCA Holders) and Series H Preferred
     Stock shall have, in addition to the other voting rights
     set forth herein, the exclusive right, voting separately
     as a class, to elect two directors of the Company to fill
     such newly created directorship, the remaining directors
     to be elected by the class or classes of stock (including
     the Series E Preferred Stock (other than BHCA Holders)
     and the Series H Preferred Stock) entitled to vote
     therefor, at each meeting of stockholders held for the
     purpose of electing directors.  In the event that at any
     time there shall occur a Four-Dividend Default or a
     Lender Default, then immediately on the happening of such
     Four-Dividend Default or Lender Default and until such
     Lender Default or Four-Dividend Default and all defaults
     in the payment of quarterly dividends on the Series E
     Preferred Stock subsequent to and occurring while such
     Four-Dividend Default exists shall be cured, then the
     number of directors constituting the Board of Directors
     of the Company shall, without further action, be further
     increased by six (in the case of a Four-Dividend Default)
     or by eight (in the case of a Lender Default) and the
     holders of Series E Preferred Stock (other than BHCA
     Holders) and the Series H Preferred Stock shall have, in
     addition to the other voting rights set forth herein, the
     exclusive right, voting separately as a class, to elect
     directors of the Company to fill such newly created
     directorships, the remaining directors to be elected by
     the class or classes of stock (including the Series E
     Preferred Stock and the Series H Preferred Stock)
     entitled to vote therefor, at each meeting of
     stockholders held for the purpose of electing directors. 
     During the existence of a Four Dividend Default, a
     majority of the Directors not elected by the holders of
     the Series E Preferred Stock and the Series H Preferred
     Stock (or their affiliates) shall have the right to
     declare and pay dividends on the Series E Preferred Stock
     and the Series H Preferred Stock out of funds legally
     available for the payment of such dividends. 
     Notwithstanding the foregoing provisions of this Section
     1.4.3, upon payment in full of all quarterly dividends on
     the Series E Preferred Stock and the Series H Preferred
     Stock coming due subsequent to a Four-Dividend Default
     and the dividend which resulted in the Four-Dividend
     Default, so that no more than three consecutive quarterly
     dividends on the Series E Preferred Stock and the Series
     H Preferred Stock remain in default, the Special Series E
     Voting Rights of the holders of Series E Preferred Stock
     and the Series H Preferred Stock shall be reduced so that
     they have the right, voting separately as a class, to
     elect two Additional Directors of the Company. 
     Notwithstanding the foregoing provisions of this Section
     1.4.3, upon payment in full of (i) all quarterly
     dividends on the Series E Preferred Stock and the Series
     H Preferred Stock coming due subsequent to a Two-Dividend
     Default and the dividend which resulted in the Two-
     Dividend Default, or (ii) upon payment in full of all
     quarterly dividends on the Series E Preferred Stock and
     the Series H Preferred Stock coming due subsequent to a
     Four-Dividend Default and three of the dividends which
     resulted in a Four-Dividend Default, so that, in each
     case, no more than one quarterly dividend remains in
     default, or (iii) upon payment in full or cure of all
     Lender Defaults, the Special Series E Voting Rights shall
     terminate.  Upon any termination of the aforesaid Special
     Series E Voting Rights, the term of office of each
     director elected by the holders of the Series E Preferred
     Stock and the Series H Preferred Stock pursuant to this
     Section 1.4.3 then in office shall thereupon terminate
     and upon such termination the number of directors
     constituting the Board of Directors shall, by resolution
     of the Board of Directors, be reduced accordingly,
     subject always to the subsequent increase of the number
     of directors from time to time pursuant to this Section
     1.4.3 in the event of the periodic future vesting of the
     right of the holders of the Series E Preferred Stock
     (other than BHCA Holders) and Series H Preferred Stock to
     elect Additional Directors.  The term of office of any
     director elected by the holders of the Series E Preferred
     Stock and Series H Preferred Stock pursuant to this
     Section 1.4.3 shall terminate upon the earlier of the
     termination of the Special Series E Voting Rights and the
     election of a successor to such director at any meeting
     of holders of the Series E Preferred Stock and the Series
     H Preferred Stock for the purpose of electing directors.

               1.4.4.  Special Series E Voting Rights may be
     exercised either at a special meeting of holders of the
     Series E Preferred Stock and the Series H Preferred
     Stock, or at any annual or special meeting of
     stockholders of the Company, or may be exercised by the
     written consent of holders of the Series E Preferred
     Stock and the Series H Preferred Stock pursuant to the
     Delaware General Corporation Law.

               1.4.5.  At any time when Special Series E
     Voting Rights pursuant to Section 1.4.3 above shall have
     vested in holders of the Series E Preferred Stock (other
     than BHCA Holders) and the Series H Preferred Stock, and
     if such rights shall have not already been initially
     exercised, a proper officer of the Company shall, upon
     the written request of any holder of record of the Series
     E Preferred Stock (other than BHCA Holders) or Series H
     Preferred Stock then outstanding, addressed to the
     secretary of the Company, call a special meeting of
     holders of the Series E Preferred Stock and Series H
     Preferred Stock for the purpose of electing directors. 
     Such meeting shall be held at the earliest practicable
     date upon the notice required for annual meetings of the
     stockholders at the place for holding annual meetings of
     the stockholders of the Company or, if none, at a place
     designated by the secretary of the Company.  If such a
     meeting shall not be called by the proper officer of the
     Company within ten (10) days after the personal service
     of such written request upon the secretary of the
     Company, or within ten (10) days after mailing the same
     within the United States, by first-class registered mail,
     addressed to the secretary of the Company at the
     Company's principal office (such mailing to be evidenced
     by registry receipt issued by the postal authorities),
     then the holders of record of ten percent (10%) of the
     shares of the Series E Preferred Stock or the Series H
     Preferred Stock then outstanding may designate in writing
     a holder of Series E Preferred Stock or Series H
     Preferred Stock to call such meeting at the expense of
     the Company, and such meeting may be called by such
     person so designated upon the notice required for annual
     meetings of stockholders and shall be held at the same
     place as is elsewhere provided in this Section 1.4.5. 
     Any holder of Series E Preferred Stock (other than BHCA
     Holders) or Series H Preferred Stock shall have access to
     the stock books of the Company for the purpose of causing
     a meeting of holders of Series E Preferred Stock (other
     than BHCA Holders) and Series H Preferred Stock to be
     called pursuant to the provisions hereof.

               1.4.6.  At any meeting held for the purpose of
     electing directors at which the holders of Series E
     Preferred Stock and Series H Preferred Stock shall have
     the right to elect directors as provided herein, the
     presence in person or by proxy of the holders of twenty-
     five percent (25%) of the then outstanding shares of
     Series E Preferred Stock and Series H Preferred Stock
     shall be required and shall be sufficient to constitute a
     quorum of such class for the election of directors by
     such class.  In the absence of a quorum of the holders of
     Series E Preferred Stock and Series H Preferred Stock
     entitled to vote for the election of directors, a
     majority of the holders present in person or by proxy of
     such class shall have the power to adjourn the meeting
     for the election of directors which the holders of such
     class are entitled to elect, from time to time, without
     notice other than announcement at the meeting, until a
     quorum shall be present.

               1.4.7.  Unless the vote of the holders of a
     greater number of shares of this Series E Preferred Stock
     shall then be required by law, the consent of the holders
     of at least 66-2/3% of all of the shares of this Series E
     Preferred Stock at the time outstanding, voting together
     as a separate class, shall be necessary for authorizing,
     effecting or validating any of the following:

               (a)  the creation, authorization or issue of
     any shares of any class or series of stock of the Company
     ranking prior to, or pari passu with, the shares of this
     Series E Preferred Stock as to dividends or upon
     liquidation or otherwise, or the reclassification of any
     authorized stock of the Company into any such prior
     shares, or the creation, authorization or issue of any
     obligation or security convertible into or evidencing the
     right to purchase any such prior shares; and 

               (b)  the amendment, alteration or repeal of any
     of the provisions of the Certificate of Incorporation or
     of any certificate amendatory thereof or supplemental
     thereto so as to affect adversely the preferences,
     rights, powers or privileges of this Series E Preferred
     Stock;

               1.5.  Redemption.

               1.5.1.  Optional Redemption.  On or after  
     August 1, 1995, the Company shall have the right to
     redeem all or part of the Series E Preferred Stock upon
     not less than ten (10) days prior written notice to the
     holders of the Series E Preferred Stock.

               No shares of Series E Preferred Stock shall be
     redeemed pursuant to this Section 1.5.1 unless
     concurrently therewith shares of Series H Preferred Stock
     are redeemed on a pro rata basis (based on the respective
     Stated Values plus Unpaid Dividends of the Series H
     Preferred Stock and the Series E Preferred Stock) and no
     shares of Series H Preferred Stock shall be redeemed
     unless concurrently therewith shares of Series E
     Preferred Stock are redeemed on a pro rata basis (based
     on the respective Stated Values plus Unpaid Dividends of
     the Series H Preferred Stock and the Series E Preferred
     Stock).

               In the event of optional redemption by the
     Company within sixty days following any occurrence of a
     Book Value Event or in the event of optional redemption
     by the Company after December 31, 2004, shares of Series
     E Preferred Stock and Series H Preferred Stock shall be
     redeemed at a redemption price equal to the Stated Value
     per share, plus all Unpaid Dividends payable with respect
     to such shares as of the date fixed for redemption,
     without interest.  In the event of optional redemption by
     the Company prior to January 1, 2005 in the absence of
     the existence of a Book Value Event, shares of Series E
     Preferred Stock and Series H Preferred Stock shall be
     redeemed at a redemption price equal to 107% of the
     Stated Value per share, plus all Unpaid Dividends payable
     with respect to such shares as of the date fixed for
     redemption without interest.  In either circumstance,
     such redemption price shall be paid in cash.

               1.5.2.  Mandatory Redemption.  The Company
     shall redeem all (but not less than all) shares of Series
     E Preferred Stock and Series H Preferred Stock on August
     1, 2004 (the "Mandatory Redemption Date") at a cash
     redemption price equal to the Stated Value per share of
     such Series E Preferred Stock and Series H Preferred
     Stock, plus all Unpaid Dividends on each such share up to
     and including the date of redemption.

     Payment shall be applied to the redemption of the shares of
     Series E Preferred Stock and Series H Preferred Stock, pro rata
     (based on the respective Stated Values plus Unpaid Dividends) 
     among the holders of all outstanding shares of the Series E
     Preferred Stock and Series H Preferred Stock on the Mandatory
     Redemption Date and shall be paid to each such holder upon
     surrender of the certificate or certificates evidencing such
     shares to be redeemed to the secretary of the Company.  If the
     Company fails to redeem all outstanding shares of Series E
     Preferred Stock and Series H Preferred Stock on the Mandatory
     Redemption Date, then the other terms of the Series E Preferred
     Stock and Series H Preferred Stock shall remain in full force
     and effect and the holder shall have no further recourse
     against the Company.

                1.5.3.  Special Redemption.  (a)  Upon the
     occurrence of any Special Redemption Event (as hereinafter
     defined), each holder of Series E Preferred Stock and Series H
     Preferred Stock shall have the right to require that the
     Company redeem, to the extent the Company lawfully may do so,
     all or a portion of the shares of Series E Preferred Stock and
     Series H Preferred Stock held by such holder, at a redemption
     price in cash equal to the Stated Value per share (plus all
     Unpaid Dividends thereon to the redemption date).  No shares of
     Series H Preferred Stock shall be redeemed pursuant to this
     Section 1.5.3 unless concurrently therewith shares of Series E
     Preferred Stock are redeemed on a pro rata basis (based on the
     respective Stated Values plus Unpaid Dividends of the Series E
     Preferred Stock and the Series H Preferred Stock) and no shares
     of Series H Preferred Stock shall be redeemed pursuant to this
     Section 1.5.3 unless concurrently therewith shares of Series E
     Preferred Stock are redeemed on a pro rata basis (based on the
     respective Stated Values plus Unpaid Dividends of the Series E
     Preferred Stock and the Series H Preferred Stock).

                (b)  Within five Business Days following any Special
     Redemption Event (as hereinafter defined), the Company will
     mail to each holder of Series E Preferred Stock and Series H
     Preferred Stock a notice (the "Special Redemption Event
     Notice") (i) stating that a Special Redemption Event has
     occurred; (ii) setting forth a purchase date (the "Special
     Redemption  Date"), which shall be no earlier than 20 Business
     Days nor later than 30 Business Days from the date the Special
     Redemption Event Notice is mailed; (iii) setting forth the
     Conversion Price then in effect with respect to such shares of
     Series E Preferred Stock and Series H Preferred Stock, pursuant
     to the provisions of Section 1.6 hereof; and (iv) setting forth
     the instructions reasonably determined by the Company,
     consistent with this Section 1.5.3 and applicable law, that a
     holder must follow in order to require the redemption of his
     Series E Preferred Stock and Series H Preferred Stock.  Holders
     of Series E Preferred Stock and Series H Preferred Stock
     seeking to require that the Company redeem their shares will be
     required to surrender their shares to the Company prior to the
     close of business on the third Business Day prior to the
     Special Redemption Date.

                (c)  Immediately prior to the redemption of any
     shares of Series E Preferred Stock and Series H Preferred Stock
     pursuant to this Section 1.5.3., the Company shall declare and
     pay a cash dividend on all outstanding shares of Series E
     Preferred Stock and Series H Preferred Stock in an amount equal
     to the aggregate amount of all accumulated and unpaid dividends
     that have been added to the Stated Value thereof and all
     accrued Unpaid Dividends thereon to the Special Redemption
     Date.  Upon the Special Redemption Date, the redemption price
     of such shares shall be payable to the order of the person
     whose name appears on the certificate or certificates
     representing such shares as the owner thereof and each
     surrendered certificate shall be cancelled.  From and after the
     date the Company shall irrevocably deposit an amount equal to
     the redemption price of the shares of Series E Preferred Stock
     and Series H Preferred Stock to be redeemed in trust for the
     holders of such shares with a bank having capital and surplus
     in excess of $100 million, which bank shall be named in the
     Special Redemption Event Notice, all rights of the holders of
     such Series E Preferred Stock and Series H Preferred Stock,
     except the right to receive such redemption price without
     interest upon surrender of their certificate or certificates,
     shall cease with respect to such shares, and such shares shall
     not thereafter be transferred on the books of the Company or be
     deemed to be outstanding for any purpose whatsoever. 

                (d)  "Special Redemption Event" shall mean:

                (i)  consummation of any merger,
             reorganization or consolidation transaction
             involving the Company;

                (ii) the acquisition by purchase or otherwise
             of a controlling interest in the business or
             assets of, or the stock or other evidence of
             beneficial ownership of, any other Person if
             consummation of such transaction results in a
             transfer of ownership of a majority of the
             voting securities of the Company to such other
             Person or its stockholders;

                (iii) the sale, lease, conveyance, transfer,
             exchange, encumbrance or other disposition, in
             one transaction or a series of related
             transactions, of more than 25% of the assets of
             the Company; provided, however, that a
             definitive agreement between the Company and a
             party with which it is currently negotiating
             that contemplates an ongoing revenue stream to
             the Company based on commercial exploitation of
             the Company's technology and requiring a payment
             to the Company upon execution of at least $1.25
             million, such payment to be not primarily in
             consideration of any requirement that the
             Company render services, shall not be deemed to
             breach this provision if such agreement is
             executed on or before July 31, 1996; or

                (iv)  the sale or other disposition of voting
             securities of the Company, in a transaction or a
             series of related transactions, if consummation
             of such transaction or transactions results in a
             transfer of ownership of a majority of the
             voting securities of the Company.

                (e)  Anything in this Section 1.5.3 to the contrary
     notwithstanding, no BHCA Holder shall be entitled to require
     that the Company redeem any of its Series G Preferred Stock
     pursuant to this Section 1.5.3 unless the Federal Reserve
     System has confirmed in advance that such redemption does not
     violate the Bank Holding Company Act of 1956, as amended.

               1.5.4.  With respect to any optional redemption of
     Series E Preferred Stock, each redemption of Series E Preferred
     Stock shall be made so that the number of shares of Series H  
     Preferred Stock held by each registered holder thereof shall be
     reduced in an amount which shall bear the same ratio to the
     total number of shares of Series E Preferred Stock being so
     redeemed as the number of shares of Series E Preferred Stock
     then held by such holder bears to the aggregate number of
     shares of Series E Preferred Stock then outstanding.

               1.5.5.  Except as otherwise provided herein, at least
     twenty (20) days before any Redemption Date (ten (10) days if
     such redemption is in connection with a Book Value Event), a
     Redemption Notice shall be mailed, postage prepaid, to each
     holder of record of the Series E Preferred Stock and Series H
     Preferred Stock which is to be redeemed, at its address shown
     on the records of the Company; provided, however, that the
     Company's failure to give such Redemption Notice shall in no
     way affect its obligation to redeem the shares of Series E
     Preferred Stock and Series H Preferred Stock as provided
     herein.  The Redemption Notice shall set forth:

               (i)  the number of shares of Series H Preferred 
          Stock held by the holder which shall be redeemed by
          the Company, and the total number of shares of Series
          E Preferred Stock and Series H Preferred Stock held
          by all holders of such series to be so redeemed;

               (ii)  the Redemption Date and the redemption
          price;

               (iii)  that the holder is to surrender to the
          Company, at the place designated therein, its
          certificate or certificates representing the shares
          of Series E Preferred Stock and Series H Preferred
          Stock to be redeemed;

               (iv)  the Conversion Price then in effect with
          respect to such shares of Preferred Stock, pursuant
          to the provisions of Section 1.6 hereof; and

               (v)  that the conversion rights of shares of
          Series E Preferred Stock and Series H Preferred Stock
          to be redeemed shall terminate at the close of
          business on the date prior to the Redemption Date.

               1.5.6.  Each holder of shares of Series E Preferred
     Stock and Series H Preferred Stock to be redeemed shall
     surrender the certificate or certificates representing such
     shares to the Company at the place designated in the Redemption
     Notice and thereupon the applicable redemption price for such
     shares shall be paid to the order of the Person whose name
     appears on such certificate or certificates and each
     surrendered certificate shall be cancelled and retired.

               1.5.7.  From and after the Redemption Date, no shares
     of Series E Preferred Stock and Series H Preferred Stock
     thereupon subject to redemption shall be entitled to any
     further accrual of any dividends pursuant to Section 1.2 hereof
     or to the conversion provisions set forth in Section 1.6
     hereof; provided, however, that sufficient funds for payment of
     the redemption price for the shares of Series E Preferred Stock
     and Series H Preferred Stock to be redeemed are deposited or
     held and set apart for that purpose at the place of payment on
     or prior to the Redemption Date.

               1.5.8.  If the Redemption Notice shall have been
     mailed as provided herein, and if on or before the Redemption
     Date specified in such notice the consideration necessary for
     such redemption shall have been set apart so as to be available
     therefor, then on and after the close of business on the
     Redemption Date the shares of Series E Preferred Stock and
     Series H Preferred Stock called for redemption, notwithstanding
     that any certificate therefor shall not have been surrendered
     for cancellation, shall no longer be deemed outstanding, and
     all rights with respect to such shares shall forthwith cease
     and terminate, except only the right of the holders thereof to
     receive upon surrender of their certificates the consideration
     payable upon redemption thereof.  In case fewer than all the
     shares represented by any such certificate are redeemed, a new
     certificate shall be issued representing the unredeemed shares
     without cost to the holder thereof.

               1.6.  Conversion Rights.

               1.6.1.  Each holder of the shares of Series E
     Preferred Stock shall have the right, at the election of such
     holder, exercised at any time and from time to time, to
     convert, subject to the terms and provisions hereof (including,
     in the case of BHCA Holders, the restrictions stated in Section
     1.14.2 hereof), all or any portion of such shares of Series E
     Preferred Stock into fully paid and non-assessable shares of
     Common Stock of the Company or any capital stock or other
     securities into which such Common Stock shall have been changed
     or any capital stock or other securities resulting from a
     reclassification thereof.  Such conversion of Series E
     Preferred Stock to shares of Common Stock shall be made at the
     Conversion Price, subject to adjustment from time to time as
     set forth herein.  Series E Preferred Stock may be converted by
     the holder thereof during normal business hours on any Business
     Day by surrender of the required number of shares of Series E
     Preferred Stock, accompanied by written evidence of the
     holder's election to convert such holder's Series E Preferred
     Stock or portion thereof, to the Company at its principal
     executive offices.  Payment of the Conversion Price for the
     shares of Common Stock specified in such election shall be made
     by applying shares of Series E Preferred Stock, valued at the
     Stated Value per share.  Payment of Unpaid Dividends, if any,
     applicable to such converted shares of Series E Preferred Stock
     shall be made in accordance with Section 1.6.5.

               1.6.2.  All or part of the outstanding shares of
     Series E Preferred Stock (other than shares held by BHCA
     Holders) shall, at the option of the Company and upon written
     notice to the holders thereof given not less than ten (10) days
     prior to the Closing of a Triggering Event be converted, by
     applying shares of Series E Preferred Stock valued at the
     Stated Value per share, as of the date and time of the Closing
     into shares of Common Stock at the Conversion Price
     automatically and without any further action by the holders of
     such shares and whether or not the certificates representing
     such shares are surrendered to the Company or its transfer
     agent.  Payment of Unpaid Dividends, if any, applicable to such
     converted shares of Series E Preferred Stock shall be made in
     accordance with Section 1.6.5.

               1.6.3.  Upon the conversion of Series E Preferred
     Stock, the holders of such Series E Preferred Stock shall
     surrender the certificates representing such shares at the
     office of the Company.  The Company shall not be obligated to
     issue certificates evidencing the shares of Common Stock
     issuable upon such conversion (or to pay any Unpaid Dividends
     in connection with such conversion) unless certificates
     evidencing such shares of Series E Preferred Stock being
     converted are either delivered to the Company or the holder
     notifies the Company that such certificates have been lost,
     stolen, or destroyed and delivers to the Company an agreement
     satisfactory to the Company to indemnify the Company from any
     loss incurred by it in connection therewith.

               1.6.4.  Each conversion of Series E Preferred Stock
     shall be deemed to have been effected immediately prior to the
     close of business on the Business Day on which such Series E
     Preferred Stock shall have been surrendered to the Company as
     provided herein (except that if such conversion is in
     connection with a Triggering Event, then such conversion shall
     be deemed to have been effected concurrently with the Closing
     of such Triggering Event), and such conversion shall be at the
     Conversion Price in effect at such time.  On each such day that
     the conversion of shares of Series E Preferred Stock is deemed
     effected, the person or persons in whose name or names any
     certificate or certificates for shares of Common Stock are
     issuable upon such conversion shall be deemed to have become
     the holder or holders of record thereof.

               1.6.5.   As promptly as practical after the
     conversion of shares of Series E Preferred Stock, in whole or
     in part, and in any event within five (5) Business Days
     thereafter (unless such conversion is in connection with a
     Triggering Event, in which event concurrently with such
     conversion), the Company at its expense (including the payment
     by it of any applicable issue, stamp or other taxes, other than
     any income taxes and other than any taxes arising by reason of
     issuance of shares of Common Stock to any person other than
     such holder) will cause to be issued in the name of and
     delivered to the holder thereof or as such holder may direct,
     (i) a certificate or certificates for the number of shares of
     Common Stock to which such holder shall be entitled upon such
     conversion plus, in lieu of any fractional shares to which such
     holder would otherwise be entitled, cash in an amount equal to
     the same fraction of the Current Market Price per share of
     Common Stock and (ii) Unpaid Dividends, if any, applicable as
     of the time of conversion to those shares of Preferred Stock
     which are converted.  Such Unpaid Dividends shall be paid in
     cash, without interest.  In case fewer than all the shares of
     Series H Preferred Stock represented by any surrendered
     certificate are converted into Common Stock, a new certificate
     representing the shares of Series H Preferred Stock not
     converted shall be issued without cost to the holder thereof. 

               1.7.  Anti-Dilution Adjustments.  The number of
     shares of Common Stock issuable upon any conversion provided
     for in Section 1.6 shall be subject to adjustment, from time to
     time, in accordance with the following provisions:

                    1.7.1.  Issuance of Additional Shares of Common
     Stock.  In case the Company at any time or from time to time
     after the date hereof shall issue or sell Additional Shares of
     Common Stock (including Additional Shares of Common Stock
     deemed to be issued pursuant to Section 1.7.3 or 1.7.4) without
     consideration or for a consideration per share less than the
     Conversion Price in effect immediately prior to such issue or
     sale, then, in each such case, subject to Section 1.7.8, such
     Conversion Price shall be reduced, concurrently with such issue
     or sale, to a price (calculated to the nearest .001 of a cent)
     determined by multiplying such Conversion Price by a fraction

               (a)  the numerator of which shall be (i) the
          number of shares of Common Stock outstanding
          immediately prior to such issue or sale plus (ii) the
          number of shares of Common Stock which the aggregate
          consideration received by the Company for the total
          number of such Additional Shares of Common Stock so
          issued or sold would purchase at such Conversion
          Price, and

               (b)  the denominator of which shall be the
          number of shares of Common Stock outstanding
          immediately after such issue or sale,

     provided that, for the purposes of this Section 1.7.1, (x)
     immediately after any Additional Shares of Common Stock are
     deemed to have been issued pursuant to Section 1.7.3 or 1.7.4,
     such Additional Shares shall be deemed to be outstanding and
     (y) treasury shares shall not be deemed to be outstanding.

               1.7.2.  Adjustment of Conversion Price Upon
     Extraordinary Dividends and Distributions.  In case the Company
     at any time or from time to time after the date hereof shall
     declare, order, pay or make a dividend or other distribution
     (including, without limitation, any distribution of other or
     additional stock or other securities or property or Options by
     way of dividend or spin-off, reclassification, recapitalization
     or similar corporate rearrangement) on the Common Stock, other
     than (a) a dividend payable in Additional Shares of Common
     Stock or (b) a cash dividend permitted pursuant to Section
     1.2.5 hereof, then, and in each such case, subject to Section
     1.7.8, the Conversion Price in effect immediately prior to the
     close of business on the record date fixed for the
     determination of holders of any class of securities entitled to
     receive such dividend or distribution shall be reduced,
     effective as of the close of business on such record date, to a
     price (calculated to the nearest .001 of a cent) determined by
     multiplying such Conversion Price by a fraction

               (a)  the numerator of which shall be the Current
          Market Price in effect on such record date or, if the
          Common Stock trades on an ex-dividend basis, on the
          date prior to the commencement of ex-dividend
          trading, less the amount of such dividend or
          distribution (as determined in good faith by the
          Board of Directors of the Company) applicable to one
          share of Common Stock,

               (b)  the denominator of which shall be such
          Current Market Price, 

     provided that, in the event that the amount of such dividend as
     so determined is equal to or greater than 25% of such Current
     Market Price or in the event that such fraction is less than
     three fourths (3/4), in lieu of the foregoing adjustment,
     adequate provision shall be made so that the holders of the
     Series H Preferred Stock shall receive, in the same form and at
     the same time such dividend is payable to holders of Common
     Stock, a pro rata share of such dividend based upon the maximum
     number of shares of Common Stock at the time issuable to such
     holders upon conversion of such Series H Preferred Stock.

               1.7.3.  Treatment of Options and Convertible
     Securities.  In case the Company at any time or from time to
     time after the date hereof shall issue, sell, grant or assume,
     or shall fix a record date for the determination of holders of
     any class of securities entitled to receive, any Options or
     Convertible Securities, then and in each such case, the maximum
     number of Additional Shares of Common Stock (as set forth in
     the instrument relating thereto, without regard to any
     provisions contained therein for a subsequent adjustment of
     such number) issuable upon the exercise of such Options or, in
     the case of Convertible Securities and Options therefor, the
     conversion or exchange of such Convertible Securities, shall be
     deemed to be Additional Shares of Common Stock issued as of the
     time of such issue, sale, grant or assumption or, in case such
     a record date shall have been fixed, as of the close of
     business on such record date (or, if the Common Stock trades on
     an ex-dividend basis, on the date prior to the commencement of
     ex-dividend trading), provided that such Additional Shares of
     Common Stock shall not be deemed to have been issued unless the
     consideration per share (determined pursuant to Section 1.7.5)
     of such shares would be less than the Conversion Price in
     effect on the date of and immediately prior to such issue,
     sale, grant or assumption or immediately prior to the close of
     business on such record date (or, if the Common Stock trades on
     an ex-dividend basis, on the date prior to the commencement of
     ex-dividend trading), as the case may be, and provided,
     further, that in any such case in which Additional Shares of
     Common Stock are deemed to be issued

               (a)  no further adjustment of the Conversion
          Price shall be made upon the subsequent issue or sale
          of Convertible Securities or shares of Common Stock
          upon the exercise of such Options or the conversion
          or exchange of such Convertible Securities;

               (b)  if such Options or Convertible Securities
          by their terms provide, with the passage of time or
          otherwise, for any increase in the consideration
          payable to the Company, or decrease in the number of
          Additional Shares of Common Stock issuable, upon the
          exercise, conversion or exchange thereof (by change
          of rate or otherwise), the Conversion Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon any such increase or decrease becoming
          effective, be recomputed to reflect such increase or
          decrease insofar as it affects such Options, or the
          rights of conversion or exchange under such
          Convertible Securities, which are outstanding at such
          time;

               (c)  upon the expiration (or purchase by the
          Company and cancellation or retirement) of any such
          Options which shall not have been exercised or the
          expiration of any rights of conversion or exchange
          under any such Convertible Securities which shall not
          have been exercised (or purchase by the Company and
          cancellation or retirement of any such Convertible
          Securities the rights of conversion or exchange under
          which shall not have been exercised), the Conversion
          Price computed upon the original issue, sale, grant
          or assumption (or upon the occurrence of the record
          date, or date prior to the commencement of ex-
          dividend trading, as the case may be, with respect
          thereto), and any subsequent adjustments based
          thereon, shall, upon such expiration (or such
          cancellation or retirement, as the case may be), be
          recomputed as if:

               (i)  in the case of Options for Common Stock or
          Convertible Securities, the only Additional Shares of
          Common Stock issued or sold were the Additional
          Shares of Common Stock, if any, actually issued or
          sold upon the exercise of such Options or the
          conversion or exchange of such Convertible Securities
          and the consideration received therefor was the
          consideration actually received by the Company for
          the issue, sale, grant or assumption of all such
          Options, whether or not exercised, plus the
          consideration actually received by the Company upon
          such exercise, or for the issue or sale of all such
          Convertible Securities which were actually converted
          or exchanged, plus the additional consideration, if
          any, actually received by the Company upon such
          conversion or exchange, and

               (ii)  in the case of Options for Convertible
          Securities, only the Convertible Securities, if any,
          actually issued or sold upon the exercise of such
          Options were issued at the time of the issue, sale,
          grant or assumption of such Options, and the
          consideration received by the Company for the
          Additional Shares of Common Stock deemed to have then
          been issued was the consideration actually received
          by the Company for the issue, sale, grant or
          assumption of all such Options, whether or not
          exercised, plus the consideration deemed to have been
          received by the Company (pursuant to Section 1.7.5)
          upon the issue or sale of such Convertible Securities
          with respect to which such Options were actually
          exercised;

               (d)  no readjustment pursuant to subdivision (b)
          or (c) above shall have the effect of increasing the
          Conversion Price by an amount in excess of the amount
          of the adjustment thereof originally made in respect
          of the issue, sale, grant or assumption of such
          Options or Convertible Securities; and

               (e)  in the case of any such Options which
          expire by their terms not more than thirty (30) days
          after the date of issue, sale, grant or assumption
          thereof, no adjustment of the Conversion Price shall
          be made until the expiration or exercise of all such
          Options, whereupon such adjustment shall be made in
          the manner provided in subdivision (c) above.

               1.7.4.  Treatment of Stock Dividends, Stock Splits,
     etc.  In case the Company at any time or from time to time
     after the date hereof shall declare or pay any dividend on the
     Common Stock payable in Common Stock, or shall effect a
     subdivision of the outstanding shares of Common Stock into a
     greater number of shares of Common Stock (by reclassification
     or otherwise than by payment of a dividend in Common Stock),
     then, and in each such case, Additional Shares of Common Stock
     shall be deemed to have been issued (a) in the case of any such
     dividend, immediately after the close of business on the record
     date for the determination of holders of any class of
     securities entitled to receive such dividend, or (b) in the
     case of any such subdivision, at the close of business on the
     date immediately prior to the day upon which such corporate
     action becomes effective.

               1.7.5.   Computation of Consideration.  For the
     purposes of this Section 1.7,

               (a)  the consideration for the issue or sale of
          any Additional Shares of Common Stock shall,
          irrespective of the accounting treatment of such
          consideration,

               (i)  insofar as it consists of cash, be computed
          at the net amount of cash received by the Company,
          without deducting any expenses paid or incurred by
          the Company or any commissions or compensation paid
          or concessions or discounts allowed to underwriters,
          dealers or others performing similar services in
          connection with such issue or sale,

               (ii)  insofar as it consists of property
          (including securities) other than cash, be computed
          at the fair value thereof at the time of such issue
          or sale, as determined in good faith by the Board of
          Directors of the Company (subject to confirmation by
          a firm of independent certified public accountants of
          recognized standing approved by the holders of a
          majority of the Series E Preferred Stock and Series H
          Preferred Stock), and

               (iii)  in case Additional Shares of Common Stock
          are issued or sold together with other stock or
          securities or other assets of the Company for a
          consideration which covers both, be the portion of
          such consideration so received, computed as provided
          in clauses (i) and (ii) above, allocable to such
          Additional Shares of Common Stock, all as determined
          in good faith by the Board of Directors of the
          Company (subject to confirmation by a firm of
          independent certified public accountants of
          recognized standing approved by the holders of a
          majority of the Series E Preferred Stock and Series H
          Preferred Stock);

               (b)  Additional Shares of Common Stock deemed to
          have been issued pursuant to Section 1.7.3, relating
          to Options and Convertible Securities, shall be
          deemed to have been issued for a consideration per
          share determined by dividing

               (i)   the total amount, if any, received and
          receivable by the Company as consideration for the
          issue, sale, grant or assumption of the Options or
          Convertible Securities in question, plus the minimum
          aggregate amount of additional consideration (as set
          forth in the instruments relating thereto, without
          regard to any provision contained therein for a
          subsequent adjustment of such consideration to
          protect against dilution) payable to the Company upon
          the exercise in full of such Options or the
          conversion or exchange of such Convertible Securities
          or, in the case of Options for Convertible
          Securities, the exercise of such Options for
          Convertible Securities and the conversion or exchange
          of such Convertible Securities, in each case
          computing such consideration as provided in the
          foregoing subdivision (a),

     by

               (ii)  the maximum number of shares of Common
          Stock (as set forth in the instruments relating
          thereto, without regard to any provision contained
          therein for a subsequent adjustment of such number to
          protect against dilution) issuable upon the exercise
          of such Options or the conversion or exchange of such
          Convertible Securities; and

               (c)  Additional Shares of Common Stock deemed to
          have been issued pursuant to Section 1.7.4, relating
          to stock dividends, stock splits, etc., shall be
          deemed to have been issued for no consideration.

               1.7.6.  Adjustments for Combinations, etc.  In case
     the outstanding shares of Common Stock shall be combined or
     consolidated, by reclassification or otherwise, into a lesser
     number of shares of Common Stock, the Conversion Price in
     effect immediately prior to such combination or consolidation
     shall, concurrently with the effectiveness of such combination
     or consolidation, be proportionately increased.

               1.7.7.  Dilution in Case of Other Securities.  In
     case any Other Securities shall be issued or sold or shall
     become subject to issue or sale upon the conversion or exchange
     of any stock (or Other Securities) of the Company (or any
     issuer of Other Securities or any other Person referred to in
     Section 1.8) or to subscription, purchase or other acquisition
     pursuant to any Options issued or granted by the Company (or
     any such other issuer or Person) for a consideration such as to
     dilute, on a basis consistent with the standards established in
     the other provisions of this Section 1.7, the conversion rights
     granted to holders of Series C Preferred Stock, then, and in
     each such case, the computations, adjustments and readjustments
     provided for in this Section 1.7 with respect to the Conversion
     Price shall be made as nearly as possible in the manner so
     provided and applied to determine the amount of Other
     Securities from time to time receivable upon the conversion of
     the shares of Series H Preferred Stock, so as to protect the
     holders of the Series H Preferred Stock against the effect of
     such dilution.

               1.7.8.  Minimum Adjustment of Conversion Price.  If
     the amount of any adjustment of the Conversion Price required
     pursuant to this Section 1.7 would be less than one-half of one
     percent (1%) of the Conversion Price in effect at the time such
     adjustment is otherwise so required to be made, such amount
     shall be carried forward and adjustment with respect thereto
     made at the time of and together with any subsequent adjustment
     which, together with such amount and any other amount or
     amounts so carried forward, shall aggregate at least one-half
     of one percent (1%) of such Conversion Price.

               1.8.  Consolidation, Merger, etc.

               1.8.1.  Adjustments for Consolidation, Merger, Sale
     of Assets, Reorganization, etc.  In case the Company after the
     date hereof (a) shall consolidate with or merge into any other
     Person and shall not be the continuing or surviving corporation
     of such consolidation or merger, or (b) shall permit any other
     Person to consolidate with or merge into the Company and the
     Company shall be the continuing or surviving Person but, in
     connection with such consolidation or merger, the Common Stock
     or Other Securities shall be changed into or exchanged for
     stock or other securities of any Other Person or cash or any
     other property, or (c) shall transfer all or substantially all
     of its properties or assets to any other Person, or (d) shall
     effect a capital reorganization or reclassification of the
     Common Stock or Other Securities (other than a capital
     reorganization or reclassification resulting in the issue of
     Additional Shares of Common Stock for which adjustment in the
     Conversion Price is provided in subsection 1.7.1 or 1.7.2),
     then, and in the case of each such transaction (excluding any
     such transaction which constitutes a Triggering Event and in
     connection with which the Company requires conversion of the
     Series E Preferred Stock), proper provision shall be made so
     that, upon the basis and the terms and in the manner provided
     herein, the holders of shares of Series E Preferred Stock, upon
     the conversion thereof at any time after the consummation of
     such transaction, shall be entitled to receive (at the
     aggregate Conversion Price in effect at the time of such
     consummation for all Common Stock or Other Securities issuable
     upon such exercise immediately prior to such consummation), in
     lieu of the Common Stock or Other Securities issuable upon such
     exercise prior to such consummation, the highest amount of
     securities, cash or other property to which such holder would
     actually have been entitled as a stockholder upon such
     consummation if such holder had exercised the conversion rights
     pertaining to the Series E Preferred Stock immediately prior
     thereto.

               1.8.2.  Assumption of Obligations.  Notwithstanding
     anything to the contrary herein provided, the Company will not
     effect any of the transactions described in subsections (a)
     through (d) of Section 1.8.1 (excluding any such transaction
     which constitutes a Triggering Event and in connection with
     which the Company requires conversion of the Series E Preferred
     Stock) unless, prior to the consummation thereof, each Person
     (other than the Company) which may be required to deliver any
     stock, securities, cash or property upon the conversion of
     shares of Series E Preferred Stock as provided herein shall
     assume, by written instrument delivered to, and reasonably
     satisfactory to, the holders of the Series E Preferred Stock
     (a) the obligations of the Company with respect to the Series E
     Preferred Stock (and if the Company shall survive the
     consummation of such transaction, such assumption shall be in
     addition to, and shall not release the Company from, any
     continuing obligations of the Company with respect to the
     Series H Preferred Stock), and (b) the obligation to deliver to
     such holder such shares of stock, securities, cash or property
     as, in accordance with the foregoing provisions of this Section
     1.8, such holder may be entitled to receive, and such Person
     shall have similarly delivered to such holders of Series E
     Preferred Stock an opinion of counsel for such Person, which
     counsel shall be reasonably satisfactory to such holders,
     stating that the rights and privileges of the Series E
     Preferred Stock shall thereafter continue in full force and
     effect and the terms thereof (including, without limitation,
     all of the provisions of this Section 1.8) shall be applicable
     to the stock, securities, cash or property which such Person
     may be required to deliver upon any conversion of shares of
     Series E Preferred Stock or the exercise of any rights pursuant
     hereto.

               1.9.  Other Dilutive Events.  In case any event shall
     occur as to which the provisions of Section 1.7 or Section 1.8
     are not strictly applicable but the failure to make any
     adjustment would not fairly protect the conversion rights
     pertaining to shares of Series E Preferred Stock in accordance
     with the essential intent and principles of such sections,
     then, in each such case, the Company shall appoint a firm of
     independent certified public accountants of recognized national
     standing (such firm to be subject to the approval of the
     holders of a majority of the Series E Preferred Stock and the
     Series H Preferred Stock"), which shall give their opinion
     regarding the adjustment, if any, on a basis consistent with
     the essential intent and principles established in Sections 1.7
     and 1.8, necessary to preserve, without dilution, the
     conversion rights of the Series E Preferred Stock and the
     Series H Preferred Stock.  Upon receipt of such opinion, the
     Company will promptly mail a copy thereof to each holder of
     Series E Preferred Stock and Series H Preferred Stock and shall
     make the adjustments described therein.

               1.10.  No Dilution or Impairment.  The Company will
     not, by amendment of its certificate of incorporation or by-
     laws or through any consolidation, merger, reorganization,
     transfer of assets, dissolution, issue or sale of securities or
     any other voluntary action, avoid or seek to avoid the
     observance or performance of any of the terms of the Series E
     Preferred Stock, but will at all times in good faith assist in
     the carrying out of all such terms and in the taking of all
     such action as may be necessary or appropriate in order to
     protect the rights of the holders of shares of Series E
     Preferred Stock against dilution or other impairment.  Without
     limiting the generality of the foregoing, the Company (a) will
     not permit the par value of any shares of stock receivable upon
     the conversion of Series E Preferred Stock to exceed the amount
     payable therefor upon such exercise, (b) will take all such
     action as may be necessary or appropriate in order that the
     Company may validly and legally issue fully paid and non-
     assessable shares of stock on the conversion of the shares of
     Series E Preferred Stock from time to time outstanding, and (c)
     will not take any action which results in any adjustment of the
     Conversion Price if the total number of shares of Common Stock
     (or Other Securities) issuable after the action upon the
     conversion of all of the outstanding shares of Series E
     Preferred Stock would exceed the total number of shares of
     Common Stock (or Other Securities) then authorized by the
     Company's certificate of incorporation and available for the
     purpose of issue upon such exercise.

               1.11.  Accountants' Report as to Adjustments.  In
     each case of any adjustment or readjustment in the shares of
     Common Stock (or Other Securities) issuable upon the conversion
     of shares of Series E Preferred Stock, the Company at its
     expense will promptly compute such adjustment or readjustment
     in accordance with the terms hereof and cause independent
     certified public accountants of recognized standing (such firm
     to be subject to the approval of the holders of a majority of
     the outstanding Series E Preferred Stock and Series H Preferred
     Stock) selected by the Company to verify such computation and
     prepare a report setting forth such adjustment or readjustment
     and showing in reasonable detail the method of calculation
     thereof and the facts upon which such adjustment or
     readjustment is based, including a statement of (a) the
     consideration received or to be received by the Company for any
     Additional Shares of Common Stock issued or sold or deemed to
     have been issued, (b) the number of shares of Common Stock
     outstanding or deemed to be outstanding, and (c) the Conversion
     Price in effect immediately prior to such issue or sale and as
     adjusted and readjusted (if required by Section 1.7) on account
     thereof.  The Company will forthwith mail a copy of each such
     report to each holder of shares of Series E Preferred Stock and
     Series H Preferred Stock and will, upon the written request at
     any time of any holder of shares of Series E Preferred Stock
     and Series H Preferred Stock, furnish to such holder a like
     report setting forth the Conversion Price at the time in effect
     and showing in reasonable detail how it was calculated.  The
     Company will also keep copies of all such reports at its
     principal office and will cause the same to be available for
     inspection at such office during normal business hours by any
     holder of Series E Preferred Stock or Series H Preferred Stock
     or any prospective purchaser of Series E Preferred Stock or
     Series H Preferred Stock designated by the holder thereof.

               1.12.  Notices of Corporate Action.  In the event of 

               (a)  any taking by the Company of a record of
          the holders of any class of securities for the
          purpose of determining the holders thereof who are
          entitled to receive any dividend (other than
          dividends payable with respect to the Series E
          Preferred Stock and the Series H Preferred Stock and
          other than a regular periodic dividend payable in
          cash out of earned surplus in an amount not exceeding
          the amount of the immediately preceding cash dividend
          for such period) or other distribution, or any right
          to subscribe for, purchase or otherwise acquire any
          shares of stock of any class or any other securities
          or property, or to receive any other right, or

               (b)  any capital reorganization of the Company,
          any reclassification or recapitalization of the
          capital stock of the Company or any consolidation or
          merger involving the Company and any other Person or
          any transfer of all or substantially all of the
          assets of the Company to any other Person, or

               (c)  any voluntary or involuntary dissolution,
          liquidation or winding-up of the Company,

     the Company will mail to each holder of shares of Series E 
     Preferred Stock and the Series H Preferred Stock a notice
     specifying (i) the date or expected date on which any such
     record is to be taken for the purpose of such dividend,
     distribution or right, and the amount and character of such
     dividend, distribution or right, and (ii) the date or expected
     date on which any such reorganization, reclassification,
     recapitalization, consolidation, merger, transfer, dissolution,
     liquidation or winding-up is to take place and the time, if any
     such time is to be fixed, as of which the holders of record of
     Common Stock (or Other Securities) shall be entitled to
     exchange their shares of Common Stock (or Other Securities) for
     the securities or other property deliverable upon such
     reorganization, reclassification, recapitalization,
     consolidation, merger, transfer, dissolution, liquidation or
     winding-up.  Except for notices relating to mandatory
     conversion or optional redemption in connection with a
     Triggering Event, such notices shall be mailed at least forty-
     five (45) days prior to the date of the action therein
     specified.

               1.13.  Retirement of Converted or Redeemed Shares. 
     No share or shares of Series E Preferred Stock acquired by the
     Company by reason of optional or mandatory redemption,
     purchase, conversion or otherwise shall be re-issued and all
     such shares shall be cancelled, retired and eliminated from the
     shares which the Company shall be authorized to issue.  The
     Company may from time to time take such appropriate corporate
     action as may be necessary to reduce the authorized number of
     shares of Series E Preferred Stock accordingly.

               1.14.  Restrictions on Transfer and Conversion of the
     Series E Preferred Stock By BHCA Holders.

               1.14.1.  A BHCA Holder may transfer Series E
     Preferred Stock only to an unaffiliated third party (a) in a
     widely dispersed public offering, (b) to one or more investors,
     in one or more transactions, none of whom, after such purchase
     would hold more than 2% of the voting securities of the Company
     then outstanding assuming that the Series E Preferred Stock
     being transferred to such investor has been fully converted by
     such investor, (c) to any Person that already controls the
     Company prior to such transfer, (d) in a transaction that
     complies with Rule 144 (or any successor thereto) of the
     Securities Act of 1933, as amended, or (e) in any other
     transaction approved in advance by the Federal Reserve System.

               1.14.2.  A BHCA Holder may only convert Series E
     Preferred Stock into Common Stock in connection with the sale
     of the Common Stock to an unaffiliated party (a) in a widely
     dispersed public offering, (b) to one or more investors, in one
     or more transactions, none of whom, after such purchase would
     hold more than 2% of the voting securities of the Company then
     outstanding, (c) to any Person that already controls the
     Company prior to such transfer, (d) in a transaction that
     complies with Rule 144 (or any successor thereto) of the
     Securities Act of 1933, as amended, or (e) in any other
     transaction approved in advance by the Federal Reserve System.

     FURTHER RESOLVED, that, before the Company shall issue any
     shares of Series E Preferred Stock, a certificate pursuant to
     Section 151 of the DGCL shall be made, executed, acknowledged,
     filed, and recorded in accordance with the provisions of
     Section 103 and 151 of the DGCL, and the proper officers of the
     Company be, and they hereby are, authorized and directed to do
     all acts and things which may be necessary or proper in their
     opinion to carry into effect the purposes and intent of this
     and the foregoing resolutions.

               IN WITNESS WHEREOF, the Company has caused this
     Certificate to be signed in its name and on its behalf and
     attested on this 30th day of January, 1996 by duly authorized
     officers of this Corporation.

                    1.1.34.  "Two-Dividend Default" means any time
          when the Company is in default in the payment of cash
          dividends on the Series F Preferred Stock and the Series
          G Preferred Stock for any two (2) consecutive Dividend
          Periods occurring after the date on which the Restricted
          Period ends or for any two Dividend Periods within any
          six (6) consecutive Dividend Periods occurring after such
          date.

                    1.1.35.  "Unpaid Dividends" means all dividends
          with respect to the Series F Preferred Stock and Series G
          Preferred Stock which have accrued but which have not
          been either paid in cash or added to the Stated Value
          thereof pursuant to Section 1.2.2.

                    1.1.36.  "Warrants" means common stock purchase
          warrants to acquire an aggregate of 290,000 shares
          (subject to adjustment as provided in such warrants)
          issued in connection with the purchase of the Series G
          Preferred Stock and Series F Preferred Stock.

                    1.2.  Dividends.

                    1.2.1.  The holder of each issued and
          outstanding share of Series F Preferred Stock and the
          Series G Preferred Stock shall be entitled to receive,
          out of the funds of the Company legally available for
          such purpose, when, as and if declared by the Board of
          Directors of the Company, before any dividend shall be
          declared, paid or set aside, or any other distribution
          shall be declared or made, upon the Common Stock or any
          other class or series of stock of the Company, dividends
          in cash at a dividend rate of nine percent (9.0%) per
          annum of the Stated Value per share of Series F Preferred
          Stock and Series G Preferred Stock, calculated on a daily
          basis, for each Dividend Period or portion thereof during
          which such Series F Preferred Stock and Series G
          Preferred Stock are outstanding.  Notwithstanding the
          foregoing, the Company may pay dividends in the form of
          Common Stock (with fractional shares to be paid in cash)
          pursuant to the terms of the Series D Preferred Stock.

                    1.2.2.    Notwithstanding anything to the
          contrary herein provided, in the event that any portion
          of the quarterly dividend for a Dividend Period on the
          Series F Preferred Stock and Series G Preferred Stock is
          not declared and paid in cash on any Dividend Payment
          Date, the amount of such accrued dividend which is not so
          paid shall be accumulated and shall automatically be
          added to the Stated Value of such share on such date. 
          Accumulated dividends on shares of Series F Preferred
          Stock and Series G Preferred Stock that have previously
          been added to the Stated Value thereof pursuant to the
          terms hereof may not thereafter be paid in cash except
          upon redemption by the Company.  Unpaid dividends shall
          not bear interest but, to the extent accumulated and
          added to the Stated Value, shall continue to accrue
          dividends on a daily basis.  Accumulated dividends on any
          share of Series F Preferred Stock and Series G Preferred
          Stock which are added to the Stated Value thereof
          pursuant to the terms hereof shall not be deemed to be in
          arrears for any purpose whatsoever.  Any dividends that
          have accrued on the Series F Preferred Stock and Series G
          Preferred Stock but have not yet been added to the Stated
          Value thereof shall constitute Unpaid Dividends. 
          Notwithstanding anything to the contrary herein provided,
          no cash dividends shall be paid with respect to the
          Common Stock, the Series A Preferred Stock, the Series B
          Preferred Stock, the Series D Preferred Stock, the Series
          E Preferred Stock or the Series H Preferred Stock at any
          time when there are Unpaid Dividends with respect to the
          Series F Preferred Stock and the Series G Preferred
          Stock.

                    1.2.3.  Dividends payable with respect to the
          Series F Preferred Stock and the Series G Preferred Stock
          shall be calculated on the basis of a 360-day year
          consisting of twelve (12) months of thirty (30) days each
          and shall be payable on each Dividend Payment Date to the
          holders of record of the Series F Preferred Stock and the
          Series G Preferred Stock at the close of business on the
          date specified by the Board of Directors of the Company;
          provided, however, that no such record date shall be more
          than thirty (30) days nor less than ten (10) days prior
          to the respective Dividend Payment Date.  Dividends on
          shares of Series F Preferred Stock and the Series G
          Preferred Stock shall accrue from the date of original
          issue of such shares of Series F Preferred Stock or
          Series G Preferred Stock.  Such dividends will accrue
          whether or not they have been declared and whether or not
          there are profits, surplus or other funds of the Company
          legally available for the payment of dividends.  The date
          on which the Company originally issues any share of
          Series F Preferred Stock or Series G Preferred Stock will
          be deemed to be its "date of original issue" regardless
          of the number of times transfer of such share is made on
          the stock records maintained by or for the Company.

                    1.2.4.  All dividends paid or added to Stated
          Value, as the case may be, with respect to shares of the
          Series F Preferred Stock or Series G Preferred Stock
          shall be paid or added to Stated Value, as the case may
          be, ratably (based on the respective Stated Values plus
          Unpaid Dividends of the Series F Preferred Stock and
          Series G Preferred Stock) with respect to such shares to
          the holders entitled thereto.

                    1.2.5.  So long as any shares of the Series F
          Preferred Stock or Series G Preferred Stock are
          outstanding, the Company shall not declare, pay or set
          apart for payment any dividend or other distribution on
          any of the Company's Common Stock, or Preferred Stock
          (other than the Series F Preferred Stock, Series G
          Preferred Stock, Series E Preferred Stock and Series H
          Preferred Stock) or make any payment on account of, or
          set apart for payment money for a sinking fund or other
          similar fund for the purchase, redemption or other
          retirement of, any of the Common Stock, or Preferred
          Stock (other than the Series F Preferred Stock or Series
          G Preferred Stock) or any warrants, rights, calls or
          options exercisable for any of the Common Stock or make
          any distribution in respect thereof, either directly or
          indirectly, and whether in cash, obligations or shares of
          the Company or other property (other than distributions
          or dividends in stock to the holders of such stock), and
          shall not permit any Person directly or indirectly
          controlled by the Company to purchase or redeem any of
          the Common Stock or Preferred Stock (other than the
          Series F Preferred Stock and Series G Preferred Stock) or
          any warrants, rights, calls or options exercisable for
          any of the Common Stock, unless prior to or concurrently
          with such declaration, payment, setting apart for
          payment, purchase or distribution, as the case may be,
          all funds then required for the mandatory redemption of
          shares of the Series F Preferred Stock and Series G
          Preferred Stock pursuant to Section 1.5.2 hereof, shall
          have been paid or be paid, and all Unpaid Dividends on
          shares of the Series F Preferred Stock and Series G
          Preferred Stock not paid in cash, shall have been paid in
          cash or be paid in cash.  Notwithstanding the foregoing,
          the Company may declare and pay dividends in the form of
          Common Stock (with fractional shares to be paid in cash)
          pursuant to the terms of the Series D Preferred Stock.
                                         
                    1.3.  Rights on Liquidation, Dissolution or
          Winding-Up.

                    1.3.1.  In the event of any liquidation,
          dissolution or winding-up of the Company (including,
          without limitation, a liquidation or reorganization under
          Chapter 7 or 11 of Title 11 of the United States Code, as
          amended), the holders of shares of the Series F Preferred
          Stock and Series G Preferred Stock then issued and
          outstanding shall be entitled to be paid out of the
          assets of the Company available for distribution to its
          stockholders, before any payment shall be made to the
          holders of Common Stock or of shares of any other class
          or series of stock of the Company, an amount equal to the
          Stated Value per share, plus an amount equal to any
          Unpaid Dividends to and including the date of
          distribution with respect to such shares.  If, upon any
          liquidation, dissolution or winding-up of the Company
          (including, without limitation, a liquidation or
          reorganization under Chapter 7 or 11 of Title 11 of the
          United States Code, as amended), the assets of the
          Company available for distribution to its stockholders
          shall be insufficient (a "Liquidation Insufficiency") to
          pay the holders of shares of the Series F Preferred Stock
          and the Series G Preferred Stock the full amounts to
          which they shall respectively be entitled, the holders of
          shares of the Series F Preferred Stock and the Series G
          Preferred Stock shall be entitled to receive all the
          assets of the Company available for distribution and each
          such holder of shares of the Series F Preferred Stock and
          the Series G Preferred Stock shall share in any
          distribution in the proportion which the aggregate Stated
          Values of the shares of the Series F Preferred Stock
          (plus all Unpaid Dividends thereon) and the Series G
          Preferred Stock (plus all Unpaid Dividends thereon) held
          by such holder of the Series F Preferred Stock or Series
          G Preferred Stock bears to the aggregate Stated Values of
          all shares of the Series F Preferred Stock (plus all
          Unpaid Dividends thereon) and Series G Preferred Stock
          (plus all Unpaid Dividends thereon) then outstanding.  If
          there is no Liquidation Insufficiency and payment shall
          have been made to the holders of shares of the Series F
          Preferred Stock and Series G Preferred Stock of the full
          amount to which they shall be entitled, then the holders
          of shares of the Series F Preferred Stock and Series G
          Preferred Stock shall be entitled to receive no further
          distributions thereon and the holders of shares of the
          Series A Preferred Stock, the Series E Preferred Stock
          and the Series H Preferred Stock shall be entitled to
          receive an amount equal to the Stated Value (plus all
          Unpaid Dividends thereon) per share thereof.  After
          payment shall have been made to the holders of shares of
          the Series A Preferred Stock, the Series E Preferred
          Stock and the Series H Preferred Stock of the full
          amounts to which they shall be entitled, the holders of
          shares of the Common Stock and of shares of any other
          class of stock of the Company, if any, shall be entitled
          to share, according to their respective rights and
          preferences, in all remaining assets of the Company
          available for distribution to its stockholders.

                    1.4.  Voting Power.

                    1.4.1.  Except as otherwise expressly provided
          herein or as required by law, (i) each holder of 
          Series F Preferred Stock shall be entitled to vote on all
          matters as to which stockholders of the Company are
          entitled to vote, and (ii) each holder of Series F
          Preferred Stock shall be entitled to cast a number of
          votes equal to the greatest number of whole shares of
          Common Stock into which such holder's shares of Series F
          Preferred Stock could be converted, pursuant to the
          provisions of Section 1.6 hereof, at the record date for
          the determination of stockholders entitled to vote on
          such matter or, if no such record date is established, at
          the date such vote is taken or any written consent of
          stockholders is solicited.  Except as otherwise expressly
          provided herein or as required by law, the holders of
          shares of Series B Preferred Stock, Series D Preferred
          Stock, Series E Preferred Stock, Series F Preferred
          Stock, Series G Preferred Stock, Series H Preferred Stock
          and Common Stock shall be entitled to vote together as a
          class with respect to all matters as to which such
          stockholders of the Company are entitled to vote.

                    1.4.2.  In the event that at any time there
          shall occur a Two-Dividend Default, then immediately upon
          the happening of such Two-Dividend Default and until such
          Two-Dividend Default and all defaults in the payment of
          quarterly dividends on the Series F Preferred Stock and
          Series G Preferred Stock subsequent to and occurring
          while such Two-Dividend Default exists shall be cured,
          the number of directors constituting the Board of
          Directors of the Company shall, without further action,
          be increased by two and the holders of Series F Preferred
          Stock and Series G Preferred Stock shall have, in
          addition to the other voting rights set forth herein, the
          exclusive right, voting together separately as a single
          class, to elect two directors of the Company to fill such
          newly created directorship, the remaining directors to be
          elected by the class or classes of stock (including the
          Series F Preferred Stock and Series G Preferred Stock)
          entitled to vote therefor, at each meeting of
          stockholders held for the purpose of electing directors. 
          In the event that at any time there shall occur a Four-
          Dividend Default or a Lender Default, then immediately on
          the happening of such Four-Dividend Default or Lender
          Default and until such Lender Default or Four-Dividend
          Default and all defaults in the payment of quarterly
          dividends on the Series F Preferred Stock and Series G
          Preferred Stock subsequent to and occurring while such
          Four-Dividend Default exists shall be cured, then the
          number of directors constituting the Board of Directors
          of the Company shall, without further action, be further
          increased by four in the case of a Four Dividend Default
          or in the case of a Lender Default, and the holders of
          Series F Preferred Stock and Series G Preferred Stock
          shall have, in addition to the other voting rights set
          forth herein, the exclusive right, voting together
          separately as a single class, to elect directors of the
          Company to fill such newly created directorships, the
          remaining directors to be elected by the class or classes
          of stock (including the Series F Preferred Stock)
          entitled to vote therefor, at each meeting of
          stockholders held for the purpose of electing directors. 
          During the existence of a Four Dividend Default, a
          majority of the Directors not elected by the holders of
          the Series F Preferred Stock and Series G Preferred Stock
          (or their affiliates) shall have the right to declare and
          pay dividends on the Series F Preferred Stock and Series
          G Preferred Stock out of funds legally available for the
          payment of such dividends.  Notwithstanding the foregoing
          provisions of this Section 1.4.2, upon payment in full of
          all quarterly dividends on the Series F Preferred Stock
          and Series G Preferred Stock coming due subsequent to a
          Four-Dividend Default and the dividend which resulted in
          the Four-Dividend Default, so that no more than three
          consecutive quarterly dividends on the Series F Preferred
          Stock and Series G Preferred Stock remain in default, the
          Special Series F Voting Rights of the holders of Series F
          Preferred Stock and Series G Preferred Stock shall be
          reduced so that they have the right, voting separately as
          a class, to elect two Additional Directors of the
          Company.  Notwithstanding the foregoing provisions of
          this Section 1.4.2, upon payment in full of (i) all
          quarterly dividends on the Series F Preferred Stock and
          Series G Preferred Stock coming due subsequent to a Two-
          Dividend Default and the dividend which resulted in the
          Two-Dividend Default, (ii) upon payment in full of all
          quarterly dividends on the Series F Preferred Stock and
          Series G Preferred Stock coming due subsequent to a Four-
          Dividend Default and three of the dividends which
          resulted in a Four-Dividend Default, so that, in each
          case, no more than one quarterly dividend remains in
          default, and (iii) upon payment in full or cure of any
          Lender Defaults, the Special Series F Voting Rights shall
          terminate.  Upon any termination of the aforesaid Special
          Series F Voting Rights, the term of office of each
          director elected by the holders of the Series F Preferred
          Stock and Series G Preferred Stock pursuant to this
          Section 1.4.2 then in office shall thereupon terminate
          and upon such termination the number of directors
          constituting the Board of Directors shall, by resolution
          of the Board of Directors, be reduced accordingly,
          subject always to the subsequent increase of the number
          of directors from time to time pursuant to this Section
          1.4.2 in the event of the periodic future vesting of the
          right of the holders of the Series F Preferred Stock and
          Series G Preferred Stock to elect Additional Directors. 
          The term of office of any director elected by the holders
          of the Series F Preferred Stock and Series G Preferred
          Stock pursuant to this Section 1.4.2 shall terminate upon
          the earlier of the termination of the Special Series F
          Voting Rights and the election of a successor to such
          director at any meeting of holders of the Series F
          Preferred Stock and Series G Preferred Stock for the
          purpose of electing directors.

                    1.4.3.  Special Series F Voting Rights may be
          exercised either at a special meeting of holders of the
          Series F Preferred Stock and Series G Preferred Stock, or
          at any annual or special meeting of stockholders of the
          Company, or may be exercised by the written consent of
          holders of the Series F Preferred Stock and Series G
          Preferred Stock pursuant to the Delaware General
          Corporation Law.

                    1.4.4.  At any time when Special Series F
          Voting Rights pursuant to Section 1.4.2 above shall have
          vested in holders of the Series F Preferred Stock and
          Series G Preferred Stock, and if such rights shall have
          not already been initially exercised, a proper officer of
          the Company shall, upon the written request of any holder
          of record of the Series F Preferred Stock and Series G
          Preferred Stock then outstanding, addressed to the
          secretary of the Company, call a special meeting of
          holders of the Series F Preferred Stock and Series G
          Preferred Stock for the purpose of electing directors. 
          Such meeting shall be held at the earliest practicable
          date upon the notice required for annual meetings of the
          stockholders at the place for holding annual meetings of
          the stockholders of the Company or, if none, at a place
          designated by the secretary of the Company.  If such a
          meeting shall not be called by the proper officer of the
          Company within ten (10) days after the personal service
          of such written request upon the secretary of the
          Company, or within ten (10) days after mailing the same
          within the United States, by first-class registered mail,
          addressed to the secretary of the Company at the
          Company's principal office (such mailing to be evidenced
          by registry receipt issued by the postal authorities),
          then the holders of record of ten percent (10%) of the
          shares of the Series F Preferred Stock or Series G
          Preferred Stock then outstanding may designate in writing
          a holder of Series F Preferred Stock or Series G
          Preferred Stock to call such meeting at the expense of
          the Company, and such meeting may be called by such
          person so designated upon the notice required for annual
          meetings of stockholders and shall be held at the same
          place as is elsewhere provided in this Section 1.4.4. 
          Any holder of Series F Preferred Stock and Series G
          Preferred Stock shall have access to the stock books of
          the Company for the purpose of causing a meeting of
          holders of Series F Preferred Stock and Series G
          Preferred Stock to be called pursuant to the provisions
          hereof.

                    1.4.5.  At any meeting held for the purpose of
          electing directors at which the holders of Series F
          Preferred Stock and Series G Preferred Stock shall have
          the right to elect directors as provided herein, the
          presence in person or by proxy of the holders of twenty-
          five percent (25%) of the then outstanding shares of
          Series F Preferred Stock and Series G Preferred Stock
          shall be required and shall be sufficient to constitute a
          quorum of such class for the election of directors by
          such series.  In the absence of a quorum of the holders
          of Series F Preferred Stock and Series G Preferred Stock
          entitled to vote for the election of directors, a
          majority of the holders present in person or by proxy of
          such Series shall have the power to adjourn the meeting
          for the election of directors which the holders of such
          Series are entitled to elect, from time to time, without
          notice other than announcement at the meeting, until a
          quorum shall be present.

                    1.4.6.  Unless the vote of the holders of a
          greater number of shares of this Series F Preferred Stock
          shall then be required by law, the consent of the holders
          of at least 66-2/3% of all of the shares of this Series F
          Preferred Stock at the time outstanding, voting together
          as a separate class, shall be necessary for authorizing,
          effecting or validating any of the following:

                    (a)  the creation, authorization or issue of
          any shares of any class or series of stock of the Company
          ranking prior to, or pari passu with, the shares of this
          Series F Preferred Stock as to dividends or upon
          liquidation or otherwise, or the reclassification of any
          authorized stock of the Company into any such prior
          shares, or the creation, authorization or issue of any
          obligation or security convertible into or evidencing the
          right to purchase any such prior shares;

                    (b)  the amendment, alteration or repeal of any
          of the provisions of the Certificate of Incorporation or
          of any certificate amendatory thereof or supplemental
          thereto so as to affect adversely the preferences,
          rights, powers or privileges of this Series F Preferred
          Stock; and

                    (c)  the issuance or assumption of any debt
          greater than $250,000 (provided, however, if the Company
          has previously redeemed a portion of the Series F
          Preferred Stock and the Series G Preferred Stock, then
          this amount may be increased up to a maximum amount
          obtained by multiplying $250,000 by a fraction that is
          the inverse of the percentage of the Series F Preferred
          Stock and Series G Preferred Stock that remains
          outstanding after such redemption).

                    1.5.  Redemption.

                    1.5.1.  Optional Redemption.  The Company shall
          have the right to redeem all or part of the Series F
          Preferred Stock upon not less than ten (10) days prior
          written notice to the holders of the Series F Preferred
          Stock.

                    No shares of Series F Preferred Stock shall be
          redeemed pursuant to this Section 1.5.1 unless
          concurrently therewith shares of Series G Preferred Stock
          are redeemed on a pro rata basis (based on the respective
          Stated Values plus Unpaid Dividends of the Series F
          Preferred Stock and the Series G Preferred Stock) and no
          shares of Series G Preferred Stock shall be redeemed
          unless concurrently therewith shares of Series F
          Preferred Stock are redeemed on a pro rata basis (based
          on the respective Stated Values plus Unpaid Dividends of
          the Series F Preferred Stock and the Series G Preferred
          Stock).

                    In the event of optional redemption by the
          Company within sixty days following any occurrence of a
          Book Value Event shares of Series F Preferred Stock and
          Series G Preferred Stock shall be redeemed at a
          redemption price equal to the Stated Value per share,
          plus all Unpaid Dividends payable with respect to such
          shares as of the date fixed for redemption, without
          interest.  In the event of optional redemption by the
          Company prior to August 1, 2004 in the absence of the
          existence of a Book Value Event, shares of Series F
          Preferred Stock and Series G Preferred Stock shall be
          redeemed at a redemption price equal to 109% of the
          Stated Value per share, plus all Unpaid Dividends payable
          with respect to such shares as of the date fixed for
          redemption without interest.  In either circumstance,
          such redemption price shall be paid in cash.

                    1.5.2.  Mandatory Redemption.  The Company
          shall redeem all (but not less than all) shares of Series
          F Preferred Stock and the Series G Preferred Stock on
          August 1, 2004 (the "Mandatory Redemption Date") at a
          cash redemption price equal to the Stated Value per share
          of such Series F Preferred Stock and Series G Preferred
          Stock, plus all Unpaid Dividends on each such share up to
          and including the date of redemption.

                     Payment shall be applied to the redemption of the
          shares of Series F Preferred Stock and the Series G Preferred
          Stock, pro rata (based on the respective Stated Values plus
          Unpaid Dividends) among the holders of all outstanding shares
          of the Series F Preferred Stock and the Series G Preferred
          Stock on the Mandatory Redemption Date and shall be paid to
          each such holder upon surrender of the certificate or
          certificates evidencing such shares to be redeemed to the
          secretary of the Company.

                     1.5.3.  Special Redemption.  (a)  Upon the
          occurrence of any Special Redemption Event (as hereinafter
          defined, each holder of Series F Preferred Stock and Series G
          Preferred Stock shall have the right to require that the
          Company redeem, to the extent the Company lawfully may do so,
          all or a portion of the shares of Series F Preferred Stock and
          Series G Preferred Stock held by such holder, at a redemption
          price in cash equal to the Stated Value per share (plus all
          Unpaid Dividends thereon to the redemption date).  No shares of
          Series F Preferred Stock shall be redeemed pursuant to this
          Section 1.5.3 unless concurrently therewith shares of Series G
          Preferred Stock are redeemed on a pro rata basis (based on the
          respective Stated Values plus Unpaid Dividends of the Series F
          Preferred Stock and the Series G Preferred Stock) and no shares
          of Series G Preferred Stock shall be redeemed pursuant to this
          Section 1.5.3 unless concurrently therewith shares of Series F
          Preferred Stock are redeemed on a pro rata basis (based on the
          respective Stated Values plus Unpaid Dividends of the Series F
          Preferred Stock and the Series G Preferred Stock).

                     (b)  Within five Business Days following any Special
          Redemption Event (as hereinafter defined), the Company will
          mail to each holder of Series F Preferred Stock and Series G
          Preferred Stock a notice (the "Special Redemption Event
          Notice") (i) stating that a Special Redemption Event has
          occurred; (ii) setting forth a purchase date (the "Special
          Redemption  Date"), which shall be no earlier than 20 Business
          Days nor later than 30 Business Days from the date the Special
          Redemption Event Notice is mailed; (iii) setting forth the
          Conversion Price then in effect with respect to such shares of
          Series F Preferred Stock and Series G Preferred Stock, pursuant
          to the provisions of Section 1.6 hereof; and (iv) setting forth
          the instructions reasonably determined by the Company,
          consistent with this Section 1.5.3 and applicable law, that a
          holder must follow in order to require the redemption of his
          Series F Preferred Stock and Series G Preferred Stock.  Holders
          of Series F Preferred Stock and Series G Preferred Stock
          seeking to require that the Company redeem their shares will be
          required to surrender their shares to the Company prior to the
          close of business on the third Business Day prior to the
          Special Redemption Date.

                     (c)  Immediately prior to the redemption of any
          shares of Series F Preferred Stock and Series G Preferred Stock
          pursuant to this Section 1.5.3., the Company shall declare and
          pay a cash dividend on all outstanding shares of Series F
          Preferred Stock and Series G Preferred Stock in an amount equal
          to the aggregate amount of all accumulated and unpaid dividends
          that have been added to the Stated Value thereof and all
          accrued Unpaid Dividends thereon to the Special Redemption
          Date.  Upon the Special Redemption Date, the redemption price
          of such shares shall be payable to the order of the person
          whose name appears on the certificate or certificates
          representing such shares as the owner thereof and each
          surrendered certificate shall be cancelled.  From and after the
          date the Company shall irrevocably deposit an amount equal to
          the redemption price of the shares of Series F Preferred Stock
          and Series G Preferred Stock to be redeemed in trust for the
          holders of such shares with a bank having capital and surplus
          in excess of $100 million, which bank shall be named in the
          Special Redemption Event Notice, all rights of the holders of
          such Series F Preferred Stock, except the right to receive such
          redemption price without interest upon surrender of their
          certificate or certificates, shall cease with respect to such
          shares, and such shares shall not thereafter be transferred on
          the books of the Company or be deemed to be outstanding for any
          purpose whatsoever. 

                     (d)  "Special Redemption Event" shall mean:

                     (i)  consummation of any merger,
                  reorganization or consolidation transaction
                  involving the Company;

                     (ii) the acquisition by purchase or otherwise
                  of a controlling interest in the business or
                  assets of, or the stock or other evidence of
                  beneficial ownership of, any other Person if
                  consummation of such transaction results in a
                  transfer of ownership of a majority of the
                  voting securities of the Company to such other
                  Person or its stockholders;

                     (iii) except in connection with the execution
                  of the agreement contemplated by Section
                  1.1.6(b) hereof, the sale, lease, conveyance,
                  transfer, exchange, encumbrance or other
                  disposition, in one transaction or a series of
                  related transactions, of more than 25% of the
                  assets of the Company; or

                     (iv)  the sale or other disposition of voting
                  securities of the Company, in a transaction or a
                  series of related transactions, if consummation
                  of such transaction or transactions results in a
                  transfer of ownership of a majority of the
                  voting securities of the Company.

                    1.5.4.  With respect to any optional redemption of
          Series F Preferred Stock, each redemption of Series F Preferred
          Stock shall be made so that the number of shares of Series F
          Preferred Stock held by each registered holder thereof shall be
          reduced in an amount which shall bear the same ratio to the
          total number of shares of Series F Preferred Stock being so
          redeemed as the number of shares of Series F Preferred Stock
          then held by such holder bears to the aggregate number of
          shares of Series F Preferred Stock then outstanding.

                    1.5.5.  Except as otherwise provided herein, at least
          twenty (20) days before any Redemption Date (ten (10) days if
          such redemption is in connection with a Book Value Event), a
          Redemption Notice shall be mailed, postage prepaid, to each
          holder of record of the Series F Preferred Stock and Series G
          Preferred Stock which is to be redeemed, at its address shown
          on the records of the Company; provided, however, that the
          Company's failure to give such Redemption Notice shall in no
          way affect its obligation to redeem the shares of Series F
          Preferred Stock and Series G Preferred Stock as provided
          herein.  The Redemption Notice shall set forth:

                    (i)  the number of shares of Series F Preferred 
               Stock held by the holder which shall be redeemed by
               the Company, and the total number of shares of Series
               F Preferred Stock and Series G Preferred Stock held
               by all holders of such series to be so redeemed;

                    (ii)  the Redemption Date and the redemption
               price;

                    (iii)  that the holder is to surrender to the
               Company, at the place designated therein, its
               certificate or certificates representing the shares
               of Series F Preferred Stock and Series G Preferred
               Stock to be redeemed;

                    (iv)  the Conversion Price then in effect with
               respect to such shares of Preferred Stock, pursuant
               to the provisions of Section 1.6 hereof; and

                    (v)  that the conversion rights of shares of
               Series F Preferred Stock and Series G Preferred Stock
               to be redeemed shall terminate at the close of
               business on the date prior to the Redemption Date.

                    1.5.6.  Each holder of shares of Series F Preferred
          Stock and Series G Preferred Stock to be redeemed shall
          surrender the certificate or certificates representing such
          shares to the Company at the place designated in the Redemption
          Notice and thereupon the applicable redemption price for such
          shares shall be paid to the order of the Person whose name
          appears on such certificate or certificates and each
          surrendered certificate shall be cancelled and retired.

                    1.5.7.  From and after the Redemption Date, no shares
          of Series F Preferred Stock and Series G Preferred Stock
          thereupon subject to redemption shall be entitled to any
          further accrual of any dividends pursuant to Section 1.2 hereof
          or to the conversion provisions set forth in Section 1.6
          hereof; provided, however, that sufficient funds for payment of
          the redemption price for the shares of Series F Preferred Stock
          and Series G Preferred Stock to be redeemed are deposited or
          held and set apart for that purpose at the place of payment on
          or prior to the Redemption Date.

                    1.5.8.  If the Redemption Notice shall have been
          mailed as provided herein, and if on or before the Redemption
          Date specified in such notice the consideration necessary for
          such redemption shall have been set apart so as to be available
          therefor, then on and after the close of business on the
          Redemption Date the shares of Series F Preferred Stock and
          Series G Preferred Stock called for redemption, notwithstanding
          that any certificate therefor shall not have been surrendered
          for cancellation, shall no longer be deemed outstanding, and
          all rights with respect to such shares shall forthwith cease
          and terminate, except only the right of the holders thereof to
          receive upon surrender of their certificates the consideration
          payable upon redemption thereof.  In case fewer than all the
          shares represented by any such certificate are redeemed, a new
          certificate shall be issued representing the unredeemed shares
          without cost to the holder thereof.

                    1.6.  Conversion Rights.

                    1.6.1.  After June 30, 1996, each holder of the
          shares of Series F Preferred Stock shall have the right, at the
          election of such holder, exercised at any time and from time to
          time, to convert, subject to the terms and provisions hereof,
          all or any portion of such shares of Series F Preferred Stock
          into fully paid and non-assessable shares of Common Stock of
          the Company or any capital stock or other securities into which
          such Common Stock shall have been changed or any capital stock
          or other securities resulting from a reclassification thereof. 
          Such conversion of Series F Preferred Stock to shares of Common
          Stock shall be made at the Conversion Price, subject to
          adjustment from time to time as set forth herein.  Series F
          Preferred Stock may be converted by the holder thereof during
          normal business hours on any Business Day by surrender of the
          required number of shares of Series F Preferred Stock,
          accompanied by written evidence of the holder's election to
          convert such holder's Series F Preferred Stock or portion
          thereof, to the Company at its principal executive offices. 
          Payment of the Conversion Price for the shares of Common Stock
          specified in such election shall be made by applying shares of
          Series F Preferred Stock, valued at the Stated Value per share. 
          Payment of Unpaid Dividends, if any, applicable to such
          converted shares of Series F Preferred Stock shall be made in
          accordance with Section 1.6.4.

                    1.6.2.  Upon the conversion of Series F Preferred
          Stock, the holders of such Series F Preferred Stock shall
          surrender the certificates representing such shares at the
          office of the Company.  The Company shall not be obligated to
          issue certificates evidencing the shares of Common Stock
          issuable upon such conversion (or to pay any Unpaid Dividends
          in connection with such conversion) unless certificates
          evidencing such shares of Series F Preferred Stock being
          converted are either delivered to the Company or the holder
          notifies the Company that such certificates have been lost,
          stolen, or destroyed and delivers to the Company an agreement
          satisfactory to the Company to indemnify the Company from any
          loss incurred by it in connection therewith.

                    1.6.3.  Each conversion of Series F Preferred Stock
          shall be deemed to have been effected immediately prior to the
          close of business on the Business Day on which such Series F
          Preferred Stock shall have been surrendered to the Company as
          provided herein, and such conversion shall be at the Conversion
          Price in effect at such time.  On each such day that the
          conversion of shares of Series F Preferred Stock is deemed
          effected, the person or persons in whose name or names any
          certificate or certificates for shares of Common Stock are
          issuable upon such conversion shall be deemed to have become
          the holder or holders of record thereof.

                    1.6.4.   As promptly as practical after the
          conversion of shares of Series F Preferred Stock, in whole or
          in part, and in any event within five (5) Business Days
          thereafter, the Company at its expense (including the payment
          by it of any applicable issue, stamp or other taxes, other than
          any income taxes and other than any taxes arising by reason of
          issuance of shares of Common Stock to any person other than
          such holder) will cause to be issued in the name of and
          delivered to the holder thereof or as such holder may direct,
          (i) a certificate or certificates for the number of shares of
          Common Stock to which such holder shall be entitled upon such
          conversion plus, in lieu of any fractional shares to which such
          holder would otherwise be entitled, cash in an amount equal to
          the same fraction of the Current Market Price per share of
          Common Stock and (ii) Unpaid Dividends, if any, applicable as
          of the time of conversion to those shares of Preferred Stock
          which are converted.  Such Unpaid Dividends shall be paid in
          cash, without interest.  In case fewer than all the shares of
          Series F Preferred Stock represented by any surrendered
          certificate are converted into Common Stock, a new certificate
          representing the shares of Series F Preferred Stock not
          converted shall be issued without cost to the holder thereof. 

                    1.7.  Anti-Dilution Adjustments.  The number of
          shares of Common Stock issuable upon any conversion provided
          for in Section 1.6 shall be subject to adjustment, from time to
          time, in accordance with the following provisions:

                    1.7.1.  Issuance of Additional Shares of Common
          Stock.  In case the Company at any time or from time to time
          after the date hereof shall issue or sell Additional Shares of
          Common Stock (including Additional Shares of Common Stock
          deemed to be issued pursuant to Section 1.7.3 or 1.7.4) without
          consideration or for a consideration per share less than the
          Conversion Price in effect immediately prior to such issue or
          sale, then, in each such case, subject to Section 1.7.8, such
          Conversion Price shall be reduced, concurrently with such issue
          or sale, to a price (calculated to the nearest .001 of a cent)
          equal to the consideration per share paid for such additional
          shares of Common Stock.

                    1.7.2.  Adjustment of Conversion Price Upon Extraor-
          dinary Dividends and Distributions.  In case the Company at any
          time or from time to time after the date hereof shall declare,
          order, pay or make a dividend or other distribution (including,
          without limitation, any distribution of other or additional
          stock or other securities or property or Options by way of
          dividend or spin-off, reclassification, recapitalization or
          similar corporate rearrangement) on the Common Stock, other
          than a dividend payable in Additional Shares of Common Stock,
          then, and in each such case, subject to Section 1.7.8, the
          Conversion Price in effect immediately prior to the close of
          business on the record date fixed for the determination of
          holders of any class of securities entitled to receive such
          dividend or distribution shall be reduced, effective as of the
          close of business on such record date, to a price (calculated
          to the nearest .001 of a cent) determined by multiplying such
          Conversion Price by a fraction

                    (a)  the numerator of which shall be the Current
          Market Price in effect on such record date or, if the Common
          Stock trades on an ex-dividend basis, on the date prior to the
          commencement of ex-dividend trading, less the amount of such
          dividend or distribution (as determined in good faith by the
          Board of Directors of the Company) applicable to one share of
          Common Stock,

                    (b)  the denominator of which shall be such Current
          Market Price, 

          provided that, in the event that the amount of such dividend as
          so determined is equal to or greater than 25% of such Current
          Market Price or in the event that such fraction is less than
          three fourths (3/4), in lieu of the foregoing adjustment,
          adequate provision shall be made so that the holders of the
          Series F Preferred Stock shall receive, in the same form and at
          the same time such dividend is payable to holders of Common
          Stock, a pro rata share of such dividend based upon the maximum
          number of shares of Common Stock at the time issuable to such
          holders upon conversion of such Series F Preferred Stock.

                    1.7.3.  Treatment of Options and Convertible Securi-
          ties.  In case the Company at any time or from time to time
          after the date hereof shall issue, sell, grant or assume, or
          shall fix a record date for the determination of holders of any
          class of securities entitled to receive, any Options or
          Convertible Securities, then and in each such case, the maximum
          number of Additional Shares of Common Stock (as set forth in
          the instrument relating thereto, without regard to any
          provisions contained therein for a subsequent adjustment of
          such number) issuable upon the exercise of such Options or, in
          the case of Convertible Securities and Options therefor, the
          conversion or exchange of such Convertible Securities, shall be
          deemed to be Additional Shares of Common Stock issued as of the
          time of such issue, sale, grant or assumption or, in case such
          a record date shall have been fixed, as of the close of
          business on such record date (or, if the Common Stock trades on
          an ex-dividend basis, on the date prior to the commencement of
          ex-dividend trading), provided that such Additional Shares of
          Common Stock shall not be deemed to have been issued unless the
          consideration per share (determined pursuant to Section 1.7.5)
          of such shares would be less than the Conversion Price in
          effect on the date of and immediately prior to such issue,
          sale, grant or assumption or immediately prior to the close of
          business on such record date (or, if the Common Stock trades on
          an ex-dividend basis, on the date prior to the commencement of
          ex-dividend trading), as the case may be, and provided,
          further, that in any such case in which Additional Shares of
          Common Stock are deemed to be issued

                    (a)  no further adjustment of the Conversion Price
          shall be made upon the subsequent issue or sale of Convertible
          Securities or shares of Common Stock upon the exercise of such
          Options or the conversion or exchange of such Convertible
          Securities;

                    (b)  if such Options or Convertible Securities by
          their terms provide, with the passage of time or otherwise, for
          any increase in the consideration payable to the Company, or
          decrease in the number of Additional Shares of Common Stock
          issuable, upon the exercise, conversion or exchange thereof (by
          change of rate or otherwise), the Conversion Price computed
          upon the original issue, sale, grant or assumption thereof (or
          upon the occurrence of the record date, or date prior to the
          commencement of ex-dividend trading, as the case may be, with
          respect thereto), and any subsequent adjustments based thereon,
          shall, upon any such increase or decrease becoming effective,
          be recomputed to reflect such increase or decrease insofar as
          it affects such Options, or the rights of conversion or
          exchange under such Convertible Securities, which are
          outstanding at such time;

                    (c)  upon the expiration (or purchase by the Company
          and cancellation or retirement) of any such Options which shall
          not have been exercised or the expiration of any rights of
          conversion or exchange under any such Convertible Securities
          which shall not have been exercised (or purchase by the Company
          and cancellation or retirement of any such Convertible
          Securities the rights of conversion or exchange under which
          shall not have been exercised), the Conversion Price computed
          upon the original issue, sale, grant or assumption (or upon the
          occurrence of the record date, or date prior to the
          commencement of ex-dividend trading, as the case may be, with
          respect thereto), and any subsequent adjustments based thereon,
          shall, upon such expiration (or such cancellation or
          retirement, as the case may be), be recomputed as if:

                    (i)  in the case of Options for Common Stock or
               Convertible Securities, the only Additional Shares of
               Common Stock issued or sold were the Additional
               Shares of Common Stock, if any, actually issued or
               sold upon the exercise of such Options or the
               conversion or exchange of such Convertible Securities
               and the consideration received therefor was the
               consideration actually received by the Company for
               the issue, sale, grant or assumption of all such
               Options, whether or not exercised, plus the
               consideration actually received by the Company upon
               such exercise, or for the issue or sale of all such
               Convertible Securities which were actually converted
               or exchanged, plus the additional consideration, if
               any, actually received by the Company upon such
               conversion or exchange, and

                    (ii)  in the case of Options for Convertible
               Securities, only the Convertible Securities, if any,
               actually issued or sold upon the exercise of such
               Options were issued at the time of the issue, sale,
               grant or assumption of such Options, and the
               consideration received by the Company for the
               Additional Shares of Common Stock deemed to have then
               been issued was the consideration actually received
               by the Company for the issue, sale, grant or
               assumption of all such Options, whether or not
               exercised, plus the consideration deemed to have been
               received by the Company (pursuant to Section 1.7.5)
               upon the issue or sale of such Convertible Securities
               with respect to which such Options were actually
               exercised;

                    (d)  no readjustment pursuant to subdivision (b) or
          (c) above shall have the effect of increasing the Conversion
          Price by an amount in excess of the amount of the adjustment
          thereof originally made in respect of the issue, sale, grant or
          assumption of such Options or Convertible Securities; and

                    (e)  in the case of any such Options which expire by
          their terms not more than thirty (30) days after the date of
          issue, sale, grant or assumption thereof, no adjustment of the
          Conversion Price shall be made until the expiration or exercise
          of all such Options, whereupon such adjustment shall be made in
          the manner provided in subdivision (c) above.

                    1.7.4.  Treatment of Stock Dividends, Stock Splits,
          etc.  In case the Company at any time or from time to time
          after the date hereof shall declare or pay any dividend on the
          Common Stock payable in Common Stock, or shall effect a
          subdivision of the outstanding shares of Common Stock into a
          greater number of shares of Common Stock (by reclassification
          or otherwise than by payment of a dividend in Common Stock),
          then, and in each such case, Additional Shares of Common Stock
          shall be deemed to have been issued (a) in the case of any such
          dividend, immediately after the close of business on the record
          date for the determination of holders of any class of
          securities entitled to receive such dividend, or (b) in the
          case of any such subdivision, at the close of business on the
          date immediately prior to the day upon which such corporate
          action becomes effective.

                    1.7.5.   Computation of Consideration.  For the
          purposes of this Section 1.7,

                    (a)  the consideration for the issue or sale of any
          Additional Shares of Common Stock shall, irrespective of the
          accounting treatment of such consideration,

                    (i)  insofar as it consists of cash, be computed
               at the net amount of cash received by the Company,
               without deducting any expenses paid or incurred by
               the Company or any commissions or compensation paid
               or concessions or discounts allowed to underwriters,
               dealers or others performing similar services in
               connection with such issue or sale,

                    (ii)  insofar as it consists of property
               (including securities) other than cash, be computed
               at the fair value thereof at the time of such issue
               or sale, as determined in good faith by the Board of
               Directors of the Company (subject to confirmation by
               a firm of independent certified public accountants of
               recognized standing approved by the holders of a
               majority of the Series F Preferred Stock and Series G
               Preferred Stock), and

                    (iii)  in case Additional Shares of Common Stock
               are issued or sold together with other stock or
               securities or other assets of the Company for a
               consideration which covers both, be the portion of
               such consideration so received, computed as provided
               in clauses (i) and (ii) above, allocable to such
               Additional Shares of Common Stock, all as determined
               in good faith by the Board of Directors of the
               Company (subject to confirmation by a firm of
               independent certified public accountants of
               recognized standing approved by the holders of a
               majority of the Series F Preferred Stock and Series G
               Preferred Stock);

                    (b)  Additional Shares of Common Stock deemed to have
          been issued pursuant to Section 1.7.3, relating to Options and
          Convertible Securities, shall be deemed to have been issued for
          a consideration per share determined by dividing

                    (i)   the total amount, if any, received and
               receivable by the Company as consideration for the
               issue, sale, grant or assumption of the Options or
               Convertible Securities in question, plus the minimum
               aggregate amount of additional consideration (as set
               forth in the instruments relating thereto, without
               regard to any provision contained therein for a
               subsequent adjustment of such consideration to
               protect against dilution) payable to the Company upon
               the exercise in full of such Options or the
               conversion or exchange of such Convertible Securities
               or, in the case of Options for Convertible
               Securities, the exercise of such Options for
               Convertible Securities and the conversion or exchange
               of such Convertible Securities, in each case
               computing such consideration as provided in the
               foregoing subdivision (a),

          by

                    (ii)  the maximum number of shares of Common
               Stock (as set forth in the instruments relating
               thereto, without regard to any provision contained
               therein for a subsequent adjustment of such number to
               protect against dilution) issuable upon the exercise
               of such Options or the conversion or exchange of such
               Convertible Securities; and

                    (c)  Additional Shares of Common Stock deemed to have
          been issued pursuant to Section 1.7.4, relating to stock
          dividends, stock splits, etc., shall be deemed to have been
          issued for no consideration.

                    1.7.6.  Adjustments for Combinations, etc.  In case
          the outstanding shares of Common Stock shall be combined or
          consolidated, by reclassification or otherwise, into a lesser
          number of shares of Common Stock, the Conversion Price in
          effect immediately prior to such combination or consolidation
          shall, concurrently with the effectiveness of such combination
          or consolidation, be proportionately increased.

                    1.7.7.  Dilution in Case of Other Securities.  In
          case any Other Securities shall be issued or sold or shall
          become subject to issue or sale upon the conversion or exchange
          of any stock (or Other Securities) of the Company (or any
          issuer of Other Securities or any other Person referred to in
          Section 1.8) or to subscription, purchase or other acquisition
          pursuant to any Options issued or granted by the Company (or
          any such other issuer or Person) for a consideration such as to
          dilute, on a basis consistent with the standards established in
          the other provisions of this Section 1.7, the conversion rights
          granted to holders of Series F Preferred Stock, then, and in
          each such case, the computations, adjustments and readjustments
          provided for in this Section 1.7 with respect to the Conversion
          Price shall be made as nearly as possible in the manner so
          provided and applied to determine the amount of Other
          Securities from time to time receivable upon the conversion of
          the shares of Series F Preferred Stock, so as to protect the
          holders of the Series F Preferred Stock against the effect of
          such dilution.

                    1.7.8.  Minimum Adjustment of Conversion Price.  If
          the amount of any adjustment of the Conversion Price required
          pursuant to this Section 1.7 would be less than one-half of one
          percent (1%) of the Conversion Price in effect at the time such
          adjustment is otherwise so required to be made, such amount
          shall be carried forward and adjustment with respect thereto
          made at the time of and together with any subsequent adjustment
          which, together with such amount and any other amount or
          amounts so carried forward, shall aggregate at least one-half
          of one percent (1%) of such Conversion Price.

                    1.8.  Consolidation, Merger, etc.

                    1.8.1.  Adjustments for Consolidation, Merger, Sale
          of Assets, Reorganization, etc.  In case the Company after the
          date hereof (a) shall consolidate with or merge into any other
          Person and shall not be the continuing or surviving corporation
          of such consolidation or merger, or (b) shall permit any other
          Person to consolidate with or merge into the Company and the
          Company shall be the continuing or surviving Person but, in
          connection with such consolidation or merger, the Common Stock
          or Other Securities shall be changed into or exchanged for
          stock or other securities of any Other Person or cash or any
          other property, or (c) shall transfer all or substantially all
          of its properties or assets to any other Person, or (d) shall
          effect a capital reorganization or reclassification of the
          Common Stock or Other Securities (other than a capital
          reorganization or reclassification resulting in the issue of
          Additional Shares of Common Stock for which adjustment in the
          Conversion Price is provided in subsection 1.7.1 or 1.7.2),
          then, and in the case of each such transaction, proper
          provision shall be made so that, upon the basis and the terms
          and in the manner provided herein, the holders of shares of
          Series F Preferred Stock, upon the conversion thereof at any
          time after the consummation of such transaction, shall be
          entitled to receive (at the aggregate Conversion Price in
          effect at the time of such consummation for all Common Stock or
          Other Securities issuable upon such exercise immediately prior
          to such consummation), in lieu of the Common Stock or Other
          Securities issuable upon such exercise prior to such
          consummation, the highest amount of securities, cash or other
          property to which such holder would actually have been entitled
          as a stockholder upon such consummation if such holder had
          exercised the conversion rights pertaining to the Series F
          Preferred Stock immediately prior thereto.

                    1.8.2.  Assumption of Obligations.  Notwithstanding
          anything to the contrary herein provided, the Company will not
          effect any of the transactions described in subsections (a)
          through (d) of Section 1.8.1 unless, prior to the consummation
          thereof, each Person (other than the Company) which may be
          required to deliver any stock, securities, cash or property
          upon the conversion of shares of Series F Preferred Stock as
          provided herein shall assume, by written instrument delivered
          to, and reasonably satisfactory to, the holders of the Series F
          Preferred Stock (a) the obligations of the Company with respect
          to the Series F Preferred Stock (and if the Company shall
          survive the consummation of such transaction, such assumption
          shall be in addition to, and shall not release the Company
          from, any continuing obligations of the Company with respect to
          the Series F Preferred Stock), and (b) the obligation to
          deliver to such holder such shares of stock, securities, cash
          or property as, in accordance with the foregoing provisions of
          this Section 1.8, such holder may be entitled to receive, and
          such Person shall have similarly delivered to such holders of
          Series F Preferred Stock an opinion of counsel for such Person,
          which counsel shall be reasonably satisfactory to such holders,
          stating that the rights and privileges of the Series F
          Preferred Stock shall thereafter continue in full force and
          effect and the terms thereof (including, without limitation,
          all of the provisions of this Section 1.8) shall be applicable
          to the stock, securities, cash or property which such Person
          may be required to deliver upon any conversion of shares of
          Series F Preferred Stock or the exercise of any rights pursuant
          hereto.

                    1.9.  Other Dilutive Events.  In case any event shall
          occur as to which the provisions of Section 1.7 or Section 1.8
          are not strictly applicable but the failure to make any
          adjustment would not fairly protect the conversion rights
          pertaining to shares of Series F Preferred Stock in accordance
          with the essential intent and principles of such sections,
          then, in each such case, the Company shall appoint a firm of
          independent certified public accountants of recognized national
          standing (such firm to be subject to the approval of the
          holders of a majority of the Series F Preferred Stock and the
          Series G Preferred Stock), which shall give their opinion
          regarding the adjustment, if any, on a basis consistent with
          the essential intent and principles established in Sections 1.7
          and 1.8, necessary to preserve, without dilution, the
          conversion rights of the Series F Preferred Stock and the
          Series G Preferred Stock.  Upon receipt of such opinion, the
          Company will promptly mail a copy thereof to each holder of
          Series F Preferred Stock and the Series G Preferred Stock and
          shall make the adjustments described therein.

                    1.10.  No Dilution or Impairment.  The Company will
          not, by amendment of its certificate of incorporation or by-
          laws or through any consolidation, merger, reorganization,
          transfer of assets, dissolution, issue or sale of securities or
          any other voluntary action, avoid or seek to avoid the
          observance or performance of any of the terms of the Series F
          Preferred Stock, but will at all times in good faith assist in
          the carrying out of all such terms and in the taking of all
          such action as may be necessary or appropriate in order to
          protect the rights of the holders of shares of Series F
          Preferred Stock against dilution or other impairment.  Without
          limiting the generality of the foregoing, the Company (a) will
          not permit the par value of any shares of stock receivable upon
          the conversion of Series F Preferred Stock to exceed the amount
          payable therefor upon such exercise, (b) will take all such
          action as may be necessary or appropriate in order that the
          Company may validly and legally issue fully paid and non-
          assessable shares of stock on the conversion of the shares of
          Series F Preferred Stock from time to time outstanding, and (c)
          will not take any action which results in any adjustment of the
          Conversion Price if the total number of shares of Common Stock
          (or Other Securities) issuable after the action upon the
          conversion of all of the outstanding shares of Series F
          Preferred Stock would exceed the total number of shares of
          Common Stock (or Other Securities) then authorized by the
          Company's certificate of incorporation and available for the
          purpose of issue upon such exercise.

                    1.11.  Accountants' Report as to Adjustments.  In
          each case of any adjustment or readjustment in the shares of
          Common Stock (or Other Securities) issuable upon the conversion
          of shares of Series F Preferred Stock, the Company at its
          expense will promptly compute such adjustment or readjustment
          in accordance with the terms hereof and cause independent
          certified public accountants of recognized standing (such firm
          to be subject to the approval of the holders of a majority of
          the outstanding Series F Preferred Stock and Series G Preferred
          Stock) selected by the Company to verify such computation and
          prepare a report setting forth such adjustment or readjustment
          and showing in reasonable detail the method of calculation
          thereof and the facts upon which such adjustment or
          readjustment is based, including a statement of (a) the
          consideration received or to be received by the Company for any
          Additional Shares of Common Stock issued or sold or deemed to
          have been issued, (b) the number of shares of Common Stock
          outstanding or deemed to be outstanding, and (c) the Conversion
          Price in effect immediately prior to such issue or sale and as
          adjusted and readjusted (if required by Section 1.7) on account
          thereof.  The Company will forthwith mail a copy of each such
          report to each holder of shares of Series F Preferred Stock and
          Series G Preferred Stock and will, upon the written request at
          any time of any holder of shares of Series F Preferred Stock
          and Series G Preferred Stock, furnish to such holder a like
          report setting forth the Conversion Price at the time in effect
          and showing in reasonable detail how it was calculated.  The
          Company will also keep copies of all such reports at its
          principal office and will cause the same to be available for
          inspection at such office during normal business hours by any
          holder of Series F Preferred Stock and Series G Preferred Stock
          or any prospective purchaser of Series F Preferred Stock or
          Series G Preferred Stock designated by the holder thereof.

                    1.12.  Notices of Corporate Action.  In the event of 

                    (a)  any taking by the Company of a record of the
          holders of any class of securities for the purpose of
          determining the holders thereof who are entitled to receive any
          dividend (other than dividends payable with respect to the
          Series F Preferred Stock and Series G Preferred Stock) or other
          distribution, or any right to subscribe for, purchase or
          otherwise acquire any shares of stock of any class or any other
          securities or property, or to receive any other right, or

                    (b)  any capital reorganization of the Company, any
          reclassification or recapitalization of the capital stock of
          the Company or any consolidation or merger involving the
          Company and any other Person or any transfer of all or
          substantially all of the assets of the Company to any other
          Person, or

                    (c)  any voluntary or involuntary dissolution,
          liquidation or winding-up of the Company,

          the Company will mail to each holder of shares of Series F 
          Preferred Stock and Series G Preferred Stock a notice
          specifying (i) the date or expected date on which any such
          record is to be taken for the purpose of such dividend,
          distribution or right, and the amount and character of such
          dividend, distribution or right, and (ii) the date or expected
          date on which any such reorganization, reclassification,
          recapitalization, consolidation, merger, transfer, dissolution,
          liquidation or winding-up is to take place and the time, if any
          such time is to be fixed, as of which the holders of record of
          Common Stock (or Other Securities) shall be entitled to
          exchange their shares of Common Stock (or Other Securities) for
          the securities or other property deliverable upon such
          reorganization, reclassification, recapitalization,
          consolidation, merger, transfer, dissolution, liquidation or
          winding-up.

                    1.13.  Retirement of Converted or Redeemed Shares. 
          No share or shares of Series F Preferred Stock acquired by the
          Company by reason of optional or mandatory redemption,
          purchase, conversion or otherwise shall be re-issued and all
          such shares shall be cancelled, retired and eliminated from the
          shares which the Company shall be authorized to issue.  The
          Company may from time to time take such appropriate corporate
          action as may be necessary to reduce the authorized number of
          shares of Series F Preferred Stock accordingly.

          FURTHER RESOLVED, that, before the Company shall issue any
          shares of Series F Preferred Stock, a certificate pursuant to
          Section 151 of the DGCL shall be made, executed, acknowledged,
          filed, and recorded in accordance with the provisions of
          Section 103 and 151 of the DGCL, and the proper officers of the
          Company be, and they hereby are, authorized and directed to do
          all acts and things which may be necessary or proper in their
          opinion to carry into effect the purposes and intent of this
          and the foregoing resolutions.

          IN WITNESS WHEREOF, the Company has caused this Certificate to
          be signed in its name and on its behalf and attested on this
          30th day of January, 1996 by duly authorized officers of this

          out of the funds of the Company legally available for
          such purpose, when, as and if declared by the Board of
          Directors of the Company, before any dividend shall be
          declared, paid or set aside, or any other distribution
          shall be declared or made, upon the Common Stock or any
          other class or series of stock of the Company, dividends
          in cash at a dividend rate of nine percent (9.0%) per

          Stock and Series G Preferred Stock, calculated on a daily
          basis, for each Dividend Period or portion thereof during
          which such Series F Preferred Stock and Series G
          Preferred Stock are outstanding.  Notwithstanding the
          foregoing, the Company may pay dividends in the form of
          Common Stock (with fractional shares to be paid in cash)
          pursuant to the terms of the Series D Preferred Stock.

                    1.2.2.    Notwithstanding anything to the

          of the quarterly dividend for a Dividend Period on the
          Series F Preferred Stock and Series G Preferred Stock is
          not declared and paid in cash on any Dividend Payment
          Date, the amount of such accrued dividend which is not so
          paid shall be accumulated and shall automatically be
          added to the Stated Value of such share on such date. 
          Accumulated dividends on shares of Series F Preferred
          Stock and Series G Preferred Stock that have previously
          been added to the Stated Value thereof pursuant to the
          terms hereof may not thereafter be paid in cash except
          upon redemption by the Company.  Unpaid dividends shall
          not bear interest but, to the extent accumulated and
          added to the Stated Value, shall continue to accrue
          dividends on a daily basis.  Accumulated dividends on any
          share of Series F Preferred Stock and Series G Preferred
          Stock which are added to the Stated Value thereof
          pursuant to the terms hereof shall not be deemed to be in

          have accrued on the Series F Preferred Stock and Series G
          Preferred Stock but have not yet been added to the Stated
          Value thereof shall constitute Unpaid Dividends. 
          Notwithstanding anything to the contrary herein provided,
          no cash dividends shall be paid with respect to the
          Common Stock, the Series A Preferred Stock, the Series B
          Preferred Stock, the Series D Preferred Stock, the Series
          E Preferred Stock or the Series H Preferred Stock at any
          time when there are Unpaid Dividends with respect to the
          Series F Preferred Stock and the Series G Preferred
          Stock.

                    1.2.3.  Dividends payable with respect to the
          Series F Preferred Stock and the Series G Preferred Stock
          shall be calculated on the basis of a 360-day year
          consisting of twelve (12) months of thirty (30) days each
          and shall be payable on each Dividend Payment Date to the
          holders of record of the Series F Preferred Stock and the
          Series G Preferred Stock at the close of business on the
          date specified by the Board of Directors of the Company;
          provided, however, that no such record date shall be more
          than thirty (30) days nor less than ten (10) days prior
          to the respective Dividend Payment Date.  Dividends on
          shares of Series F Preferred Stock and the Series G
          Preferred Stock shall accrue from the date of original
          issue of such shares of Series F Preferred Stock or
          Series G Preferred Stock.  Such dividends will accrue
          whether or not they have been declared and whether or not
          there are profits, surplus or other funds of the Company
          legally available for the payment of dividends.  The date
          on which the Company originally issues any share of
          Series F Preferred Stock or Series G Preferred Stock will
          be deemed to be its "date of original issue" regardless
          of the number of times transfer of such share is made on
          the stock records maintained by or for the Company.

                    1.2.4.  All dividends paid or added to Stated
          Value, as the case may be, with respect to shares of the
          Series F Preferred Stock or Series G Preferred Stock
          shall be paid or added to Stated Value, as the case may
          be, ratably (based on the respective Stated Values plus
          Unpaid Dividends of the Series F Preferred Stock and
          Series G Preferred Stock) with respect to such shares to
          the holders entitled thereto.

                    1.2.5.  So long as any shares of the Series F
          Preferred Stock or Series G Preferred Stock are
          outstanding, the Company shall not declare, pay or set
          apart for payment any dividend or other distribution on
          any of the Company's Common Stock, or Preferred Stock
          (other than the Series F Preferred Stock, Series G
          Preferred Stock, Series E Preferred Stock and Series H
          Preferred Stock) or make any payment on account of, or
          set apart for payment money for a sinking fund or other
          similar fund for the purchase, redemption or other
          retirement of, any of the Common Stock, or Preferred
          Stock (other than the Series F Preferred Stock or Series
          G Preferred Stock) or any warrants, rights, calls or
          options exercisable for any of the Common Stock or make
          any distribution in respect thereof, either directly or
          indirectly, and whether in cash, obligations or shares of
          the Company or other property (other than distributions
          or dividends in stock to the holders of such stock), and
          shall not permit any Person directly or indirectly
          controlled by the Company to purchase or redeem any of
          the Common Stock or Preferred Stock (other than the
          Series F Preferred Stock and Series G Preferred Stock) or
          any warrants, rights, calls or options exercisable for
          any of the Common Stock, unless prior to or concurrently
          with such declaration, payment, setting apart for
          payment, purchase or distribution, as the case may be,
          all funds then required for the mandatory redemption of
          shares of the Series F Preferred Stock and Series G
          Preferred Stock pursuant to Section 1.5.2 hereof, shall
          have been paid or be paid, and all Unpaid Dividends on
          shares of the Series F Preferred Stock and Series G
          Preferred Stock not paid in cash, shall have been paid in
          cash or be paid in cash.  Notwithstanding the foregoing,
          the Company may declare and pay dividends in the form of
          Common Stock (with fractional shares to be paid in cash)
          pursuant to the terms of the Series D Preferred Stock.

                    1.3.  Rights on Liquidation, Dissolution or
          Winding-Up.

                    1.3.1.  In the event of any liquidation,

          without limitation, a liquidation or reorganization under

          amended), the holders of shares of the Series F Preferred
          Stock and Series G Preferred Stock then issued and
          outstanding shall be entitled to be paid out of the
          assets of the Company available for distribution to its
          stockholders, before any payment shall be made to the

          have been made to the holders of shares of the Series F
          Preferred Stock and Series G Preferred Stock of the full

          the happening of such Two-Dividend Default and until such
          Two-Dividend Default and all defaults in the payment of
          quarterly dividends on the Series F Preferred Stock and
          Series G Preferred Stock subsequent to and occurring
          while such Two-Dividend Default exists shall be cured,
          the number of directors constituting the Board of
          Directors of the Company shall, without further action,
          be increased by two and the holders of Series F Preferred
          Stock and Series G Preferred Stock (other than BHCA
          Holders) shall have, in addition to the other voting
          rights set forth herein, the exclusive right, voting
          together separately as a single class, to elect two
          directors of the Company to fill such newly created
          directorship, the remaining directors to be elected by
          the class or classes of stock (including the Series F
          Preferred Stock and Series G Preferred Stock (other than
          BHCA Holders)) entitled to vote therefor, at each meeting
          of stockholders held for the purpose of electing
          directors.  In the event that at any time there shall
          occur a Four-Dividend Default or a Lender Default, then
          immediately on the happening of such Four-Dividend
          Default or Lender Default and until such Lender Default
          or Four-Dividend Default and all defaults in the payment
          of quarterly dividends on the Series F Preferred Stock
          and Series G Preferred Stock subsequent to and occurring
          while such Four-Dividend Default exists shall be cured,
          then the number of directors constituting the Board of
          Directors of the Company shall, without further action,
          be further increased by four in the case of a Four
          Dividend Default or in the case of a Lender Default, and
          the holders of Series F Preferred Stock and Series G
          Preferred Stock (other than BHCA Holders) shall have, in
          addition to the other voting rights set forth herein, the
          exclusive right, voting together separately as a single
          class, to elect directors of the Company to fill such
          newly created directorships, the remaining directors to
          be elected by the class or classes of stock (including
          the Series G Preferred Stock) entitled to vote therefor,
          at each meeting of stockholders held for the purpose of
          electing directors.  During the existence of a Four
          Dividend Default, a majority of the Directors not elected
          by the holders of the Series F Preferred Stock and Series
          G Preferred Stock (or their affiliates) shall have the
          right to declare and pay dividends on the Series F
          Preferred Stock and Series G Preferred Stock out of funds
          legally available for the payment of such dividends. 
          Notwithstanding the foregoing provisions of this Section
          1.4.2, upon payment in full of all quarterly dividends on
          the Series F Preferred Stock and Series G Preferred Stock
          coming due subsequent to a Four-Dividend Default and the
          dividend which resulted in the Four-Dividend Default, so
          that no more than three consecutive quarterly dividends
          on the Series F Preferred Stock and Series G Preferred
          Stock remain in default, the Special Series G Voting
          Rights of the holders of Series F Preferred Stock and
          Series G Preferred Stock shall be reduced so that they
          have the right, voting separately as a class, to elect
          two Additional Directors of the Company.  Notwithstanding
          the foregoing provisions of this Section 1.4.2, (i) upon
          payment in full of all quarterly dividends on the Series
          F Preferred Stock and Series G Preferred Stock coming due
          subsequent to a Two-Dividend Default and the dividend
          which resulted in the Two-Dividend Default, (ii) upon
          payment in full of all quarterly dividends on the Series
          F Preferred Stock and Series G Preferred Stock coming due
          subsequent to a Four-Dividend Default and three of the
          dividends which resulted in a Four-Dividend Default, so
          that, in each case, no more than one quarterly dividend
          remains in default, and (iii) upon payment in full or
          cure of any Lender Defaults, the Special Series G Voting
          Rights shall terminate.  Upon any termination of the
          aforesaid Special Series G Voting Rights, the term of
          office of each director elected by the holders of the
          Series F Preferred Stock and Series G Preferred Stock
          pursuant to this Section 1.4.2 then in office shall
          thereupon terminate and upon such termination the number
          of directors constituting the Board of Directors shall,
          by resolution of the Board of Directors, be reduced
          accordingly, subject always to the subsequent increase of
          the number of directors from time to time pursuant to
          this Section 1.4.2 in the event of the periodic future
          vesting of the right of the holders of the Series F
          Preferred Stock and Series G Preferred Stock (other than
          BHCA Holders) to elect Additional Directors.  The term of
          office of any director elected by the holders of the
          Series F Preferred Stock and Series G Preferred Stock
          pursuant to this Section 1.4.2 shall terminate upon the
          earlier of the termination of the Special Series G Voting
          Rights and the election of a successor to such director
          at any meeting of holders of the Series F Preferred Stock
          and Series G Preferred Stock for the purpose of electing
          directors.

                    1.4.3.  Special Series G Voting Rights may be
          exercised either at a special meeting of holders of the
          Series F Preferred Stock and Series G Preferred Stock, or
          at any annual or special meeting of stockholders of the
          Company, or may be exercised by the written consent of
          holders of the Series F Preferred Stock and Series G
          Preferred Stock pursuant to the Delaware General
          Corporation Law.

                    1.4.4.  At any time when Special Series G
          Voting Rights pursuant to Section 1.4.2 above shall have
          vested in holders of the Series F Preferred Stock and
          Series G Preferred Stock (other than BHCA Holders), and
          if such rights shall have not already been initially
          exercised, a proper officer of the Company shall, upon
          the written request of any holder of record of the Series
          F Preferred Stock and Series G Preferred Stock (other
          than BHCA Holders) then outstanding, addressed to the
          secretary of the Company, call a special meeting of
          holders of the Series F Preferred Stock and Series G
          Preferred Stock for the purpose of electing directors. 
          Such meeting shall be held at the earliest practicable
          date upon the notice required for annual meetings of the
          stockholders at the place for holding annual meetings of
          the stockholders of the Company or, if none, at a place
          designated by the secretary of the Company.  If such a
          meeting shall not be called by the proper officer of the
          Company within ten (10) days after the personal service
          of such written request upon the secretary of the
          Company, or within ten (10) days after mailing the same
          within the United States, by first-class registered mail,
          addressed to the secretary of the Company at the
          Company's principal office (such mailing to be evidenced
          by registry receipt issued by the postal authorities),
          then the holders of record of ten percent (10%) of the
          shares of the Series F Preferred Stock or Series G
          Preferred Stock then outstanding may designate in writing
          a holder of Series F Preferred Stock or Series G
          Preferred Stock to call such meeting at the expense of
          the Company, and such meeting may be called by such
          person so designated upon the notice required for annual
          meetings of stockholders and shall be held at the same
          place as is elsewhere provided in this Section 1.4.4. 
          Any holder of Series F Preferred Stock and Series G
          Preferred Stock (other than BHCA Holders) shall have
          access to the stock books of the Company for the purpose
          of causing a meeting of holders of Series F Preferred
          Stock and Series G Preferred Stock (other than BHCA
          Holders) to be called pursuant to the provisions hereof.

                    1.4.5.  At any meeting held for the purpose of
          electing directors at which the holders of Series F
          Preferred Stock and Series G Preferred Stock shall have
          the right to elect directors as provided herein, the
          presence in person or by proxy of the holders of twenty-
          five percent (25%) of the then outstanding shares of
          Series F Preferred Stock and Series G Preferred Stock
          shall be required and shall be sufficient to constitute a
          quorum of such class for the election of directors by
          such series.  In the absence of a quorum of the holders
          of Series F Preferred Stock and Series G Preferred Stock
          entitled to vote for the election of directors, a
          majority of the holders present in person or by proxy of
          such Series shall have the power to adjourn the meeting
          for the election of directors which the holders of such
          Series are entitled to elect, from time to time, without
          notice other than announcement at the meeting, until a
          quorum shall be present.

                    1.4.6.  Unless the vote of the holders of a
          greater number of shares of this Series G Preferred Stock
          shall then be required by law, the consent of the holders
          of at least 66-2/3% of all of the shares of this Series G
          Preferred Stock at the time outstanding, voting together
          as a separate class, shall be necessary for authorizing,
          effecting or validating any of the following:

                    (a)  the creation, authorization or issue of
          any shares of any class or series of stock of the Company
          ranking prior to, or pari passu with, the shares of this
          Series G Preferred Stock as to dividends or upon
          liquidation or otherwise, or the reclassification of any
          authorized stock of the Company into any such prior
          shares, or the creation, authorization or issue of any
          obligation or security convertible into or evidencing the
          right to purchase any such prior shares;

                    (b)  the amendment, alteration or repeal of any
          of the provisions of the Certificate of Incorporation or
          of any certificate amendatory thereof or supplemental
          thereto so as to affect adversely the preferences,
          rights, powers or privileges of this Series G Preferred
          Stock; and

                    (c)  the issuance or assumption of any debt
          greater than $250,000 (provided, however, if the Company
          has previously redeemed a portion of the Series F
          Preferred Stock and the Series G Preferred Stock, then
          this amount may be increased up to a maximum amount
          obtained by multiplying $250,000 by a fraction that is
          the inverse of the percentage of the Series F Preferred
          Stock and Series G Preferred Stock that remains
          outstanding after such redemption).

                    1.5.  Redemption.

                    1.5.1.  Optional Redemption.  The Company shall
          have the right to redeem all or part of the Series G
          Preferred Stock upon not less than ten (10) days prior
          written notice to the holders of the Series G Preferred
          Stock.

                    No shares of Series G Preferred Stock shall be
          redeemed pursuant to this Section 1.5.1 unless
          concurrently therewith shares of Series F Preferred Stock
          are redeemed on a pro rata basis (based on the respective
          Stated Values plus Unpaid Dividends of the Series F
          Preferred Stock and the Series G Preferred Stock) and no
          shares of Series F Preferred Stock shall be redeemed
          unless concurrently therewith shares of Series G
          Preferred Stock are redeemed on a pro rata basis (based
          on the respective Stated Values plus Unpaid Dividends of
          the Series F Preferred Stock and the Series G Preferred
          Stock).

                    In the event of optional redemption by the
          Company within sixty days following any occurrence of a
          Book Value Event shares of Series F Preferred Stock and
          Series G Preferred Stock shall be redeemed at a
          redemption price equal to the Stated Value per share,
          plus all Unpaid Dividends payable with respect to such
          shares as of the date fixed for redemption, without
          interest.  In the event of optional redemption by the
          Company prior to August 1, 2004 in the absence of the
          existence of a Book Value Event, shares of Series F
          Preferred Stock and Series G Preferred Stock shall be
          redeemed at a redemption price equal to 109% of the
          Stated Value per share, plus all Unpaid Dividends payable
          with respect to such shares as of the date fixed for
          redemption without interest.  In either circumstance,
          such redemption price shall be paid in cash.

                    1.5.2.  Mandatory Redemption.  The Company
          shall redeem all (but not less than all) shares of Series
          F Preferred Stock and the Series G Preferred Stock on
          August 1, 2004 (the "Mandatory Redemption Date") at a
          cash redemption price equal to the Stated Value per share
          of such Series F Preferred Stock and Series G Preferred
          Stock, plus all Unpaid Dividends on each such share up to
          and including the date of redemption.

                     Payment shall be applied to the redemption of the
          shares of Series F Preferred Stock and the Series G Preferred
          Stock, pro rata (based on the respective Stated Values plus
          Unpaid Dividends) among the holders of all outstanding shares
          of the Series F Preferred Stock and the Series G Preferred
          Stock on the Mandatory Redemption Date and shall be paid to
          each such holder upon surrender of the certificate or
          certificates evidencing such shares to be redeemed to the
          secretary of the Company.

                     1.5.3.  Special Redemption.  (a)  Upon the
          occurrence of any Special Redemption Event (as hereinafter
          defined, each holder of Series F Preferred Stock and Series G
          Preferred Stock shall have the right to require that the
          Company redeem, to the extent the Company lawfully may do so,
          all or a portion of the shares of Series F Preferred Stock and
          Series G Preferred Stock held by such holder, at a redemption
          price in cash equal to the Stated Value per share (plus all
          Unpaid Dividends thereon to the redemption date).  No shares of
          Series F Preferred Stock shall be redeemed pursuant to this
          Section 1.5.3 unless concurrently therewith shares of Series G
          Preferred Stock are redeemed on a pro rata basis (based on the
          respective Stated Values plus Unpaid Dividends of the Series F
          Preferred Stock and the Series G Preferred Stock) and no shares
          of Series G Preferred Stock shall be redeemed pursuant to this
          Section 1.5.3 unless concurrently therewith shares of Series F
          Preferred Stock are redeemed on a pro rata basis (based on the
          respective Stated Values plus Unpaid Dividends of the Series F
          Preferred Stock and the Series G Preferred Stock).

                     (b)  Within five Business Days following any Special
          Redemption Event (as hereinafter defined), the Company will
          mail to each holder of Series F Preferred Stock and Series G
          Preferred Stock a notice (the "Special Redemption Event
          Notice") (i) stating that a Special Redemption Event has
          occurred; (ii) setting forth a purchase date (the "Special
          Redemption  Date"), which shall be no earlier than 20 Business
          Days nor later than 30 Business Days from the date the Special
          Redemption Event Notice is mailed; (iii) setting forth the
          Conversion Price then in effect with respect to such shares of
          Series F Preferred Stock and Series G Preferred Stock, pursuant
          to the provisions of Section 1.6 hereof; and (iv) setting forth
          the instructions reasonably determined by the Company,
          consistent with this Section 1.5.3 and applicable law, that a
          holder must follow in order to require the redemption of his
          Series F Preferred Stock and Series G Preferred Stock.  Holders
          of Series F Preferred Stock and Series G Preferred Stock
          seeking to require that the Company redeem their shares will be
          required to surrender their shares to the Company prior to the
          close of business on the third Business Day prior to the
          Special Redemption Date.

                     (c)  Immediately prior to the redemption of any
          shares of Series F Preferred Stock and Series G Preferred Stock
          pursuant to this Section 1.5.3., the Company shall declare and
          pay a cash dividend on all outstanding shares of Series F
          Preferred Stock and Series G Preferred Stock in an amount equal
          to the aggregate amount of all accumulated and unpaid dividends
          that have been added to the Stated Value thereof and all
          accrued Unpaid Dividends thereon to the Special Redemption
          Date.  Upon the Special Redemption Date, the redemption price
          of such shares shall be payable to the order of the person
          whose name appears on the certificate or certificates
          representing such shares as the owner thereof and each
          surrendered certificate shall be cancelled.  From and after the
          date the Company shall irrevocably deposit an amount equal to
          the redemption price of the shares of Series F Preferred Stock
          and Series G Preferred Stock to be redeemed in trust for the
          holders of such shares with a bank having capital and surplus
          in excess of $100 million, which bank shall be named in the
          Special Redemption Event Notice, all rights of the holders of
          such Series F Preferred Stock, except the right to receive such
          redemption price without interest upon surrender of their
          certificate or certificates, shall cease with respect to such
          shares, and such shares shall not thereafter be transferred on
          the books of the Company or be deemed to be outstanding for any
          purpose whatsoever. 

                     (d)  "Special Redemption Event" shall mean:

                     (i)  consummation of any merger,
                  reorganization or consolidation transaction
                  involving the Company;

                     (ii) the acquisition by purchase or otherwise
                  of a controlling interest in the business or
                  assets of, or the stock or other evidence of
                  beneficial ownership of, any other Person if
                  consummation of such transaction results in a
                  transfer of ownership of a majority of the
                  voting securities of the Company to such other
                  Person or its stockholders;

                     (iii) except in connection with the execution
                  of the agreement contemplated by Section
                  1.1.7(b) hereof, the sale, lease, conveyance,
                  transfer, exchange, encumbrance or other
                  disposition, in one transaction or a series of
                  related transactions, of more than 25% of the
                  assets of the Company; or

                     (iv)  the sale or other disposition of voting
                  securities of the Company, in a transaction or a
                  series of related transactions, if consummation
                  of such transaction or transactions results in a
                  transfer of ownership of a majority of the
                  voting securities of the Company.

                     (e)  Anything in this Section 1.5.3 to the contrary
          notwithstanding, no BHCA Holder shall be entitled to require
          that the Company redeem any of its Series G Preferred Stock
          pursuant to this Section 1.5.3 unless the Federal Reserve
          System has confirmed in advance that such redemption does not
          violate the Bank Holding Company Act of 1956, as amended.

                    1.5.4.  With respect to any optional redemption of
          Series G Preferred Stock, each redemption of Series G Preferred
          Stock shall be made so that the number of shares of Series G
          Preferred Stock held by each registered holder thereof shall be
          reduced in an amount which shall bear the same ratio to the
          total number of shares of Series G Preferred Stock being so
          redeemed as the number of shares of Series G Preferred Stock
          then held by such holder bears to the aggregate number of
          shares of Series G Preferred Stock then outstanding.

                    1.5.5.  Except as otherwise provided herein, at least
          twenty (20) days before any Redemption Date (ten (10) days if
          such redemption is in connection with a Book Value Event), a
          Redemption Notice shall be mailed, postage prepaid, to each
          holder of record of the Series F Preferred Stock and Series G
          Preferred Stock which is to be redeemed, at its address shown
          on the records of the Company; provided, however, that the
          Company's failure to give such Redemption Notice shall in no
          way affect its obligation to redeem the shares of Series F
          Preferred Stock and Series G Preferred Stock as provided
          herein.  The Redemption Notice shall set forth:

                    (i)  the number of shares of Series F Preferred 
               Stock held by the holder which shall be redeemed by
               the Company, and the total number of shares of Series
               F Preferred Stock and Series G Preferred Stock held
               by all holders of such series to be so redeemed;

                    (ii)  the Redemption Date and the redemption
               price;

                    (iii)  that the holder is to surrender to the
               Company, at the place designated therein, its
               certificate or certificates representing the shares
               of Series F Preferred Stock and Series G Preferred
               Stock to be redeemed;

                    (iv)  the Conversion Price then in effect with
               respect to such shares of Preferred Stock, pursuant
               to the provisions of Section 1.6 hereof; and

                    (v)  that the conversion rights of shares of
               Series F Preferred Stock and Series G Preferred Stock
               to be redeemed shall terminate at the close of
               business on the date prior to the Redemption Date.

                    1.5.6.  Each holder of shares of Series F Preferred
          Stock and Series G Preferred Stock to be redeemed shall
          surrender the certificate or certificates representing such
          shares to the Company at the place designated in the Redemption
          Notice and thereupon the applicable redemption price for such
          shares shall be paid to the order of the Person whose name
          appears on such certificate or certificates and each
          surrendered certificate shall be cancelled and retired.

                    1.5.7.  From and after the Redemption Date, no shares
          of Series F Preferred Stock and Series G Preferred Stock
          thereupon subject to redemption shall be entitled to any
          further accrual of any dividends pursuant to Section 1.2 hereof
          or to the conversion provisions set forth in Section 1.6
          hereof; provided, however, that sufficient funds for payment of
          the redemption price for the shares of Series F Preferred Stock
          and Series G Preferred Stock to be redeemed are deposited or
          held and set apart for that purpose at the place of payment on
          or prior to the Redemption Date.


                    1.5.8.  If the Redemption Notice shall have been
          mailed as provided herein, and if on or before the Redemption
          Date specified in such notice the consideration necessary for
          such redemption shall have been set apart so as to be available
          therefor, then on and after the close of business on the
          Redemption Date the shares of Series F Preferred Stock and
          Series G Preferred Stock called for redemption, notwithstanding
          that any certificate therefor shall not have been surrendered
          for cancellation, shall no longer be deemed outstanding, and
          all rights with respect to such shares shall forthwith cease
          and terminate, except only the right of the holders thereof to
          receive upon surrender of their certificates the consideration
          payable upon redemption thereof.  In case fewer than all the
          shares represented by any such certificate are redeemed, a new
          certificate shall be issued representing the unredeemed shares
          without cost to the holder thereof.

                    1.6.  Conversion Rights.

                    1.6.1.  After June 30, 1996, each holder of the
          shares of Series G Preferred Stock shall have the right, at the
          election of such holder, exercised at any time and from time to
          time, to convert, subject to the terms and provisions hereof
          (including, in the case of BHCA Holders, the restrictions
          stated in Section 1.14.2 hereof), all or any portion of such
          shares of Series G Preferred Stock into fully paid and non-
          assessable shares of Common Stock of the Company or any capital
          stock or other securities into which such Common Stock shall
          have been changed or any capital stock or other securities
          resulting from a reclassification thereof.  Such conversion of
          Series G Preferred Stock to shares of Common Stock shall be
          made at the Conversion Price, subject to adjustment from time
          to time as set forth herein.  Series G Preferred Stock may be
          converted by the holder thereof during normal business hours on
          any Business Day by surrender of the required number of shares
          of Series G Preferred Stock, accompanied by written evidence of
          the holder's election to convert such holder's Series G
          Preferred Stock or portion thereof, to the Company at its
          principal executive offices.  Payment of the Conversion Price
          for the shares of Common Stock specified in such election shall
          be made by applying shares of Series G Preferred Stock, valued
          at the Stated Value per share.  Payment of Unpaid Dividends, if
          any, applicable to such converted shares of Series G Preferred
          Stock shall be made in accordance with Section 1.6.4.

                    1.6.2.  Upon the conversion of Series G Preferred
          Stock, the holders of such Series G Preferred Stock shall
          surrender the certificates representing such shares at the
          office of the Company.  The Company shall not be obligated to
          issue certificates evidencing the shares of Common Stock
          issuable upon such conversion (or to pay any Unpaid Dividends
          in connection with such conversion) unless certificates
          evidencing such shares of Series G Preferred Stock being
          converted are either delivered to the Company or the holder
          notifies the Company that such certificates have been lost,
          stolen, or destroyed and delivers to the Company an agreement
          satisfactory to the Company to indemnify the Company from any
          loss incurred by it in connection therewith.

                    1.6.3.  Each conversion of Series G Preferred Stock
          shall be deemed to have been effected immediately prior to the
          close of business on the Business Day on which such Series F
          Preferred Stock shall have been surrendered to the Company as
          provided herein, and such conversion shall be at the Conversion
          Price in effect at such time.  On each such day that the
          conversion of shares of Series G Preferred Stock is deemed
          effected, the person or persons in whose name or names any
          certificate or certificates for shares of Common Stock are
          issuable upon such conversion shall be deemed to have become
          the holder or holders of record thereof.

                    1.6.4.   As promptly as practical after the
          conversion of shares of Series G Preferred Stock, in whole or
          in part, and in any event within five (5) Business Days
          thereafter, the Company at its expense (including the payment
          by it of any applicable issue, stamp or other taxes, other than
          any income taxes and other than any taxes arising by reason of
          issuance of shares of Common Stock to any person other than
          such holder) will cause to be issued in the name of and
          delivered to the holder thereof or as such holder may direct,
          (i) a certificate or certificates for the number of shares of
          Common Stock to which such holder shall be entitled upon such
          conversion plus, in lieu of any fractional shares to which such
          holder would otherwise be entitled, cash in an amount equal to
          the same fraction of the Current Market Price per share of
          Common Stock and (ii) Unpaid Dividends, if any, applicable as
          of the time of conversion to those shares of Preferred Stock
          which are converted.  Such Unpaid Dividends shall be paid in
          cash, without interest.  In case fewer than all the shares of
          Series G Preferred Stock represented by any surrendered
          certificate are converted into Common Stock, a new certificate
          representing the shares of Series G Preferred Stock not
          converted shall be issued without cost to the holder thereof.

                    1.7.  Anti-Dilution Adjustments.  The number of
          shares of Common Stock issuable upon any conversion provided
          for in Section 1.6 shall be subject to adjustment, from time to
          time, in accordance with the following provisions:

                    1.7.1.  Issuance of Additional Shares of Common
          Stock.  In case the Company at any time or from time to time
          after the date hereof shall issue or sell Additional Shares of
          Common Stock (including Additional Shares of Common Stock
          deemed to be issued pursuant to Section 1.7.3 or 1.7.4) without
          consideration or for a consideration per share less than the
          Conversion Price in effect immediately prior to such issue or
          sale, then, in each such case, subject to Section 1.7.8, such
          Conversion Price shall be reduced, concurrently with such issue
          or sale, to a price (calculated to the nearest .001 of a cent)
          equal to the consideration per share paid for such additional
          shares of Common Stock.

                    1.7.2.  Adjustment of Conversion Price Upon
          Extraordinary Dividends and Distributions.  In case the Company
          at any time or from time to time after the date hereof shall
          declare, order, pay or make a dividend or other distribution
          (including, without limitation, any distribution of other or
          additional stock or other securities or property or Options by
          way of dividend or spin-off, reclassification, recapitalization
          or similar corporate rearrangement) on the Common Stock, other
          than a dividend payable in Additional Shares of Common Stock,
          then, and in each such case, subject to Section 1.7.8, the
          Conversion Price in effect immediately prior to the close of
          business on the record date fixed for the determination of
          holders of any class of securities entitled to receive such
          dividend or distribution shall be reduced, effective as of the
          close of business on such record date, to a price (calculated
          to the nearest .001 of a cent) determined by multiplying such
          Conversion Price by a fraction

                    (a)  the numerator of which shall be the Current
          Market Price in effect on such record date or, if the Common
          Stock trades on an ex-dividend basis, on the date prior to the
          commencement of ex-dividend trading, less the amount of such
          dividend or distribution (as determined in good faith by the
          Board of Directors of the Company) applicable to one share of
          Common Stock,

                    (b)  the denominator of which shall be such Current
          Market Price, 

          provided that, in the event that the amount of such dividend as
          so determined is equal to or greater than 25% of such Current
          Market Price or in the event that such fraction is less than
          three fourths (3/4), in lieu of the foregoing adjustment,
          adequate provision shall be made so that the holders of the
          Series F Preferred Stock shall receive, in the same form and at
          the same time such dividend is payable to holders of Common
          Stock, a pro rata share of such dividend based upon the maximum
          number of shares of Common Stock at the time issuable to such
          holders upon conversion of such Series F Preferred Stock.

                    1.7.3.  Treatment of Options and Convertible
          Securities.  In case the Company at any time or from time to
          time after the date hereof shall issue, sell, grant or assume,
          or shall fix a record date for the determination of holders of
          any class of securities entitled to receive, any Options or
          Convertible Securities, then and in each such case, the maximum
          number of Additional Shares of Common Stock (as set forth in
          the instrument relating thereto, without regard to any
          provisions contained therein for a subsequent adjustment of
          such number) issuable upon the exercise of such Options or, in
          the case of Convertible Securities and Options therefor, the
          conversion or exchange of such Convertible Securities, shall be
          deemed to be Additional Shares of Common Stock issued as of the
          time of such issue, sale, grant or assumption or, in case such
          a record date shall have been fixed, as of the close of
          business on such record date (or, if the Common Stock trades on
          an ex-dividend basis, on the date prior to the commencement of
          ex-dividend trading), provided that such Additional Shares of
          Common Stock shall not be deemed to have been issued unless the
          consideration per share (determined pursuant to Section 1.7.5)
          of such shares would be less than the Conversion Price in
          effect on the date of and immediately prior to such issue,
          sale, grant or assumption or immediately prior to the close of
          business on such record date (or, if the Common Stock trades on
          an ex-dividend basis, on the date prior to the commencement of
          ex-dividend trading), as the case may be, and provided,
          further, that in any such case in which Additional Shares of
          Common Stock are deemed to be issued

                    (a)  no further adjustment of the Conversion Price
          shall be made upon the subsequent issue or sale of Convertible
          Securities or shares of Common Stock upon the exercise of such
          Options or the conversion or exchange of such Convertible
          Securities;

                    (b)  if such Options or Convertible Securities by
          their terms provide, with the passage of time or otherwise, for
          any increase in the consideration payable to the Company, or
          decrease in the number of Additional Shares of Common Stock
          issuable, upon the exercise, conversion or exchange thereof (by
          change of rate or otherwise), the Conversion Price computed
          upon the original issue, sale, grant or assumption thereof (or
          upon the occurrence of the record date, or date prior to the
          commencement of ex-dividend trading, as the case may be, with
          respect thereto), and any subsequent adjustments based thereon,
          shall, upon any such increase or decrease becoming effective,
          be recomputed to reflect such increase or decrease insofar as
          it affects such Options, or the rights of conversion or
          exchange under such Convertible Securities, which are
          outstanding at such time;

                    (c)  upon the expiration (or purchase by the Company
          and cancellation or retirement) of any such Options which shall
          not have been exercised or the expiration of any rights of
          conversion or exchange under any such Convertible Securities
          which shall not have been exercised (or purchase by the Company
          and cancellation or retirement of any such Convertible
          Securities the rights of conversion or exchange under which
          shall not have been exercised), the Conversion Price computed
          upon the original issue, sale, grant or assumption (or upon the
          occurrence of the record date, or date prior to the
          commencement of ex-dividend trading, as the case may be, with
          respect thereto), and any subsequent adjustments based thereon,
          shall, upon such expiration (or such cancellation or
          retirement, as the case may be), be recomputed as if:

                    (i)  in the case of Options for Common Stock or
               Convertible Securities, the only Additional Shares of
               Common Stock issued or sold were the Additional
               Shares of Common Stock, if any, actually issued or
               sold upon the exercise of such Options or the
               conversion or exchange of such Convertible Securities
               and the consideration received therefor was the
               consideration actually received by the Company for
               the issue, sale, grant or assumption of all such
               Options, whether or not exercised, plus the
               consideration actually received by the Company upon
               such exercise, or for the issue or sale of all such
               Convertible Securities which were actually converted
               or exchanged, plus the additional consideration, if
               any, actually received by the Company upon such
               conversion or exchange, and

                    (ii)  in the case of Options for Convertible
               Securities, only the Convertible Securities, if any,
               actually issued or sold upon the exercise of such
               Options were issued at the time of the issue, sale,
               grant or assumption of such Options, and the
               consideration received by the Company for the
               Additional Shares of Common Stock deemed to have then
               been issued was the consideration actually received
               by the Company for the issue, sale, grant or
               assumption of all such Options, whether or not
               exercised, plus the consideration deemed to have been
               received by the Company (pursuant to Section 1.7.5)
               upon the issue or sale of such Convertible Securities
               with respect to which such Options were actually
               exercised;

                    (d)  no readjustment pursuant to subdivision (b) or
          (c) above shall have the effect of increasing the Conversion
          Price by an amount in excess of the amount of the adjustment
          thereof originally made in respect of the issue, sale, grant or
          assumption of such Options or Convertible Securities; and

                    (e)  in the case of any such Options which expire by
          their terms not more than thirty (30) days after the date of
          issue, sale, grant or assumption thereof, no adjustment of the
          Conversion Price shall be made until the expiration or exercise
          of all such Options, whereupon such adjustment shall be made in
          the manner provided in subdivision (c) above.

                    1.7.4.  Treatment of Stock Dividends, Stock Splits,
          etc.  In case the Company at any time or from time to time
          after the date hereof shall declare or pay any dividend on the
          Common Stock payable in Common Stock, or shall effect a
          subdivision of the outstanding shares of Common Stock into a
          greater number of shares of Common Stock (by reclassification
          or otherwise than by payment of a dividend in Common Stock),
          then, and in each such case, Additional Shares of Common Stock
          shall be deemed to have been issued (a) in the case of any such
          dividend, immediately after the close of business on the record
          date for the determination of holders of any class of
          securities entitled to receive such dividend, or (b) in the
          case of any such subdivision, at the close of business on the
          date immediately prior to the day upon which such corporate
          action becomes effective.

                    1.7.5.   Computation of Consideration.  For the
          purposes of this Section 1.7,

                    (a)  the consideration for the issue or sale of any
          Additional Shares of Common Stock shall, irrespective of the
          accounting treatment of such consideration,

                    (i)  insofar as it consists of cash, be computed
               at the net amount of cash received by the Company,
               without deducting any expenses paid or incurred by
               the Company or any commissions or compensation paid
               or concessions or discounts allowed to underwriters,
               dealers or others performing similar services in
               connection with such issue or sale,

                    (ii)  insofar as it consists of property
               (including securities) other than cash, be computed
               at the fair value thereof at the time of such issue
               or sale, as determined in good faith by the Board of
               Directors of the Company (subject to confirmation by
               a firm of independent certified public accountants of
               recognized standing approved by the holders of a
               majority of the Series F Preferred Stock and Series G
               Preferred Stock), and

                    (iii)  in case Additional Shares of Common Stock
               are issued or sold together with other stock or
               securities or other assets of the Company for a
               consideration which covers both, be the portion of
               such consideration so received, computed as provided
               in clauses (i) and (ii) above, allocable to such
               Additional Shares of Common Stock, all as determined
               in good faith by the Board of Directors of the
               Company (subject to confirmation by a firm of
               independent certified public accountants of
               recognized standing approved by the holders of a
               majority of the Series F Preferred Stock and Series G
               Preferred Stock);

                    (b)  Additional Shares of Common Stock deemed to have
          been issued pursuant to Section 1.7.3, relating to Options and
          Convertible Securities, shall be deemed to have been issued for
          a consideration per share determined by dividing

                    (i)   the total amount, if any, received and
               receivable by the Company as consideration for the
               issue, sale, grant or assumption of the Options or
               Convertible Securities in question, plus the minimum
               aggregate amount of additional consideration (as set
               forth in the instruments relating thereto, without
               regard to any provision contained therein for a
               subsequent adjustment of such consideration to
               protect against dilution) payable to the Company upon
               the exercise in full of such Options or the
               conversion or exchange of such Convertible Securities
               or, in the case of Options for Convertible
               Securities, the exercise of such Options for
               Convertible Securities and the conversion or exchange
               of such Convertible Securities, in each case
               computing such consideration as provided in the
               foregoing subdivision (a),

          by

                    (ii)  the maximum number of shares of Common
               Stock (as set forth in the instruments relating
               thereto, without regard to any provision contained
               therein for a subsequent adjustment of such number to
               protect against dilution) issuable upon the exercise
               of such Options or the conversion or exchange of such
               Convertible Securities; and

                    (c)  Additional Shares of Common Stock deemed to have
          been issued pursuant to Section 1.7.4, relating to stock
          dividends, stock splits, etc., shall be deemed to have been
          issued for no consideration.

                    1.7.6.  Adjustments for Combinations, etc.  In case
          the outstanding shares of Common Stock shall be combined or
          consolidated, by reclassification or otherwise, into a lesser
          number of shares of Common Stock, the Conversion Price in
          effect immediately prior to such combination or consolidation
          shall, concurrently with the effectiveness of such combination
          or consolidation, be proportionately increased.

                    1.7.7.  Dilution in Case of Other Securities.  In
          case any Other Securities shall be issued or sold or shall
          become subject to issue or sale upon the conversion or exchange
          of any stock (or Other Securities) of the Company (or any
          issuer of Other Securities or any other Person referred to in
          Section 1.8) or to subscription, purchase or other acquisition
          pursuant to any Options issued or granted by the Company (or
          any such other issuer or Person) for a consideration such as to
          dilute, on a basis consistent with the standards established in
          the other provisions of this Section 1.7, the conversion rights
          granted to holders of Series F Preferred Stock, then, and in
          each such case, the computations, adjustments and readjustments
          provided for in this Section 1.7 with respect to the Conversion
          Price shall be made as nearly as possible in the manner so
          provided and applied to determine the amount of Other
          Securities from time to time receivable upon the conversion of
          the shares of Series F Preferred Stock, so as to protect the
          holders of the Series F Preferred Stock against the effect of
          such dilution.

                    1.7.8.  Minimum Adjustment of Conversion Price.  If
          the amount of any adjustment of the Conversion Price required
          pursuant to this Section 1.7 would be less than one-half of one
          percent (1%) of the Conversion Price in effect at the time such
          adjustment is otherwise so required to be made, such amount
          shall be carried forward and adjustment with respect thereto
          made at the time of and together with any subsequent adjustment
          which, together with such amount and any other amount or
          amounts so carried forward, shall aggregate at least one-half
          of one percent (1%) of such Conversion Price.

                    1.8.  Consolidation, Merger, etc.

                    1.8.1.  Adjustments for Consolidation, Merger, Sale
          of Assets, Reorganization, etc.  In case the Company after the
          date hereof (a) shall consolidate with or merge into any other
          Person and shall not be the continuing or surviving corporation
          of such consolidation or merger, or (b) shall permit any other
          Person to consolidate with or merge into the Company and the
          Company shall be the continuing or surviving Person but, in
          connection with such consolidation or merger, the Common Stock
          or Other Securities shall be changed into or exchanged for
          stock or other securities of any Other Person or cash or any
          other property, or (c) shall transfer all or substantially all
          of its properties or assets to any other Person, or (d) shall
          effect a capital reorganization or reclassification of the
          Common Stock or Other Securities (other than a capital
          reorganization or reclassification resulting in the issue of
          Additional Shares of Common Stock for which adjustment in the
          Conversion Price is provided in subsection 1.7.1 or 1.7.2),
          then, and in the case of each such transaction, proper
          provision shall be made so that, upon the basis and the terms
          and in the manner provided herein, the holders of shares of
          Series F Preferred Stock, upon the conversion thereof at any
          time after the consummation of such transaction, shall be
          entitled to receive (at the aggregate Conversion Price in
          effect at the time of such consummation for all Common Stock or
          Other Securities issuable upon such exercise immediately prior
          to such consummation), in lieu of the Common Stock or Other
          Securities issuable upon such exercise prior to such
          consummation, the highest amount of securities, cash or other
          property to which such holder would actually have been entitled
          as a stockholder upon such consummation if such holder had
          exercised the conversion rights pertaining to the Series F
          Preferred Stock immediately prior thereto.

                    1.8.2.  Assumption of Obligations.  Notwithstanding
          anything to the contrary herein provided, the Company will not
          effect any of the transactions described in subsections (a)
          through (d) of Section 1.8.1 unless, prior to the consummation
          thereof, each Person (other than the Company) which may be
          required to deliver any stock, securities, cash or property
          upon the conversion of shares of Series G Preferred Stock as
          provided herein shall assume, by written instrument delivered
          to, and reasonably satisfactory to, the holders of the Series F
          Preferred Stock (a) the obligations of the Company with respect
          to the Series G Preferred Stock (and if the Company shall
          survive the consummation of such transaction, such assumption
          shall be in addition to, and shall not release the Company
          from, any continuing obligations of the Company with respect to
          the Series F Preferred Stock), and (b) the obligation to
          deliver to such holder such shares of stock, securities, cash
          or property as, in accordance with the foregoing provisions of
          this Section 1.8, such holder may be entitled to receive, and
          such Person shall have similarly delivered to such holders of
          Series G Preferred Stock an opinion of counsel for such Person,
          which counsel shall be reasonably satisfactory to such holders,
          stating that the rights and privileges of the Series G
          Preferred Stock shall thereafter continue in full force and
          effect and the terms thereof (including, without limitation,
          all of the provisions of this Section 1.8) shall be applicable
          to the stock, securities, cash or property which such Person
          may be required to deliver upon any conversion of shares of
          Series G Preferred Stock or the exercise of any rights pursuant
          hereto.

                    1.9.  Other Dilutive Events.  In case any event shall
          occur as to which the provisions of Section 1.7 or Section 1.8
          are not strictly applicable but the failure to make any
          adjustment would not fairly protect the conversion rights
          pertaining to shares of Series G Preferred Stock in accordance
          with the essential intent and principles of such sections,
          then, in each such case, the Company shall appoint a firm of
          independent certified public accountants of recognized national
          standing (such firm to be subject to the approval of the
          holders of a majority of the Series F Preferred Stock and the
          Series G Preferred Stock), which shall give their opinion
          regarding the adjustment, if any, on a basis consistent with
          the essential intent and principles established in Sections 1.7
          and 1.8, necessary to preserve, without dilution, the
          conversion rights of the Series F Preferred Stock and the
          Series G Preferred Stock.  Upon receipt of such opinion, the
          Company will promptly mail a copy thereof to each holder of
          Series F Preferred Stock and the Series G Preferred Stock and
          shall make the adjustments described therein.

                    1.10.  No Dilution or Impairment.  The Company will
          not, by amendment of its certificate of incorporation or by-
          laws or through any consolidation, merger, reorganization,
          transfer of assets, dissolution, issue or sale of securities or
          any other voluntary action, avoid or seek to avoid the
          observance or performance of any of the terms of the Series G
          Preferred Stock, but will at all times in good faith assist in
          the carrying out of all such terms and in the taking of all
          such action as may be necessary or appropriate in order to
          protect the rights of the holders of shares of Series G
          Preferred Stock against dilution or other impairment.  Without
          limiting the generality of the foregoing, the Company (a) will
          not permit the par value of any shares of stock receivable upon
          the conversion of Series G Preferred Stock to exceed the amount
          payable therefor upon such exercise, (b) will take all such
          action as may be necessary or appropriate in order that the
          Company may validly and legally issue fully paid and non-
          assessable shares of stock on the conversion of the shares of
          Series G Preferred Stock from time to time outstanding, and (c)
          will not take any action which results in any adjustment of the
          Conversion Price if the total number of shares of Common Stock
          (or Other Securities) issuable after the action upon the
          conversion of all of the outstanding shares of Series G
          Preferred Stock would exceed the total number of shares of
          Common Stock (or Other Securities) then authorized by the
          Company's certificate of incorporation and available for the
          purpose of issue upon such exercise.

                    1.11.  Accountants' Report as to Adjustments.  In
          each case of any adjustment or readjustment in the shares of
          Common Stock (or Other Securities) issuable upon the conversion
          of shares of Series G Preferred Stock, the Company at its
          expense will promptly compute such adjustment or readjustment
          in accordance with the terms hereof and cause independent
          certified public accountants of recognized standing (such firm
          to be subject to the approval of the holders of a majority of
          the outstanding Series F Preferred Stock and Series G Preferred
          Stock) selected by the Company to verify such computation and
          prepare a report setting forth such adjustment or readjustment
          and showing in reasonable detail the method of calculation
          thereof and the facts upon which such adjustment or
          readjustment is based, including a statement of (a) the
          consideration received or to be received by the Company for any
          Additional Shares of Common Stock issued or sold or deemed to
          have been issued, (b) the number of shares of Common Stock
          outstanding or deemed to be outstanding, and (c) the Conversion
          Price in effect immediately prior to such issue or sale and as
          adjusted and readjusted (if required by Section 1.7) on account
          thereof.  The Company will forthwith mail a copy of each such
          report to each holder of shares of Series F Preferred Stock and
          Series G Preferred Stock and will, upon the written request at
          any time of any holder of shares of Series F Preferred Stock
          and Series G Preferred Stock, furnish to such holder a like
          report setting forth the Conversion Price at the time in effect
          and showing in reasonable detail how it was calculated.  The
          Company will also keep copies of all such reports at its
          principal office and will cause the same to be available for
          inspection at such office during normal business hours by any
          holder of Series F Preferred Stock and Series G Preferred Stock
          or any prospective purchaser of Series F Preferred Stock or
          Series G Preferred Stock designated by the holder thereof.

                    1.12.  Notices of Corporate Action.  In the event of 

                    (a)  any taking by the Company of a record of the
          holders of any class of securities for the purpose of
          determining the holders thereof who are entitled to receive any
          dividend (other than dividends payable with respect to the
          Series F Preferred Stock and Series G Preferred Stock) or other
          distribution, or any right to subscribe for, purchase or
          otherwise acquire any shares of stock of any class or any other
          securities or property, or to receive any other right, or

                    (b)  any capital reorganization of the Company, any
          reclassification or recapitalization of the capital stock of
          the Company or any consolidation or merger involving the
          Company and any other Person or any transfer of all or
          substantially all of the assets of the Company to any other
          Person, or

                    (c)  any voluntary or involuntary dissolution,
          liquidation or winding-up of the Company,

          the Company will mail to each holder of shares of Series F 
          Preferred Stock and Series G Preferred Stock a notice
          specifying (i) the date or expected date on which any such
          record is to be taken for the purpose of such dividend,
          distribution or right, and the amount and character of such
          dividend, distribution or right, and (ii) the date or expected
          date on which any such reorganization, reclassification,
          recapitalization, consolidation, merger, transfer, dissolution,
          liquidation or winding-up is to take place and the time, if any
          such time is to be fixed, as of which the holders of record of
          Common Stock (or Other Securities) shall be entitled to
          exchange their shares of Common Stock (or Other Securities) for
          the securities or other property deliverable upon such
          reorganization, reclassification, recapitalization,
          consolidation, merger, transfer, dissolution, liquidation or
          winding-up.

                    1.13.  Retirement of Converted or Redeemed Shares. 
          No share or shares of Series G Preferred Stock acquired by the
          Company by reason of optional or mandatory redemption,
          purchase, conversion or otherwise shall be re-issued and all
          such shares shall be cancelled, retired and eliminated from the
          shares which the Company shall be authorized to issue.  The
          Company may from time to time take such appropriate corporate
          action as may be necessary to reduce the authorized number of
          shares of Series G Preferred Stock accordingly.

                    1.14.  Restrictions on Transfer and Conversion of the
          Series G Preferred Stock By BHCA Holders.

                    1.14.1.  A BHCA Holder may transfer Series G
          Preferred Stock only to an unaffiliated third party (a) in a
          widely dispersed public offering, (b) to one or more investors,
          in one or more transactions, none of whom, after such purchase
          would hold more than 2% of the voting securities of the Company
          then outstanding assuming that the Series G Preferred Stock
          being transferred to such investor has been fully converted by
          such investor, (c) to any Person that already controls the
          Company prior to such transfer, (d) in a transaction that
          complies with Rule 144 (or any successor thereto) of the
          Securities Act of 1933, as amended, or (e) in any other
          transaction approved in advance by the Federal Reserve System.

                    1.14.2.  A BHCA Holder may only convert Series G
          Preferred Stock into Common Stock in connection with the sale
          of the Common Stock to an unaffiliated party (a) in a widely
          dispersed public offering, (b) to one or more investors, in one
          or more transactions, none of whom, after such purchase would
          hold more than 2% of the voting securities of the Company then
          outstanding, (c) to any Person that already controls the
          Company prior to such transfer, (d) in a transaction that
          complies with Rule 144 (or any successor thereto) of the
          Securities Act of 1933, as amended, or (e) in any other
          transaction approved in advance by the Federal Reserve System.

          FURTHER RESOLVED, that, before the Company shall issue any
          shares of Series G Preferred Stock, a certificate pursuant to
          Section 151 of the DGCL shall be made, executed, acknowledged,
          filed, and recorded in accordance with the provisions of
          Section 103 and 151 of the DGCL, and the proper officers of the
          Company be, and they hereby are, authorized and directed to do
          all acts and things which may be necessary or proper in their
          opinion to carry into effect the purposes and intent of this
          and the foregoing resolutions.


          IN WITNESS WHEREOF, the Company has caused this Certificate to
          be signed in its name and on its behalf and attested on this
          30th day of January, 1996 by duly authorized officers of this
          Corporation.

          Nestor, Inc. (the "Company"), a corporation organized and
          existing under the General Corporation Law of the State
          of Delaware, does hereby certify that pursuant to the
          provisions of Section 151 of the General Corporation Law
          of the State of Delaware, the Board of Directors of the
          Company, by action taken on January 13, 1996, adopted the
          following resolution, which resolution remains in full
          force and effect as of the date hereof;

          WHEREAS, the Board of Directors of the Company is
          authorized, within the limitations and restrictions
          stated in the Certificate of Incorporation, to fix by
          resolution or resolutions the designation of each series
          of preferred stock and the powers, preferences and
          relative, participating, optional or other special rights
          and qualifications, limitations or restrictions thereof,
          including, without limiting the generality of the
          foregoing, such provisions as may be desired concerning
          voting, redemption, dividends, dissolution or the
          distribution of assets, conversion or exchange, and such
          other subjects or matters as may be fixed by resolution
          or resolutions of the Board of Directors under the
          General Corporation Law of Delaware; and

          WHEREAS, it is the desire of the Board of Directors of
          the Company pursuant to its authority as aforesaid, to
          authorize and fix the terms of a series of preferred
          stock and the number of shares constituting such series;

          NOW, THEREFORE, BE IT RESOLVED, that there is hereby
          authorized such series of preferred stock on the terms
          and with the provisions herein set forth:

          Designation, Amount and Rank.  Two thousand twenty-six
          (2,026) shares of a convertible preferred stock, $1.00
          par value per share, shall constitute a series of such
          preferred stock designated as "Series H Convertible
          Preferred Stock" (the "Series H Preferred Stock").  With
          respect to dividend rights, redemption rights and rights
          on liquidation, winding up and dissolution, the Series H
          Preferred Stock (i) shall rank junior to the Series F
          Preferred Stock and the Series G Preferred Stock, (ii)
          shall rank pari passus with the Series A Preferred Stock
          and Series E Preferred Stock, and (iii) shall rank prior
          to the Series B Preferred Stock, the Series D Preferred
          Stock, the Common Stock and any other class of capital
          stock or series of preferred stock hereafter created. 
          The Series H Preferred Stock shall be issued pursuant to
          the following additional terms and conditions:

                    1.  Series H Preferred Stock.

          whatsoever.  Any dividends that have accrued on the
          Series E Preferred Stock and Series H Preferred Stock but
          have not yet been added to the Stated Value thereof shall
          constitute Unpaid Dividends.  Notwithstanding anything to
          the contrary herein provided, no cash dividends shall be
          paid with respect to the Common Stock, the Series A
          Preferred Stock, the Series B Preferred Stock or the
          Series D Preferred Stock at any time when there are

          Series E Preferred Stock and the Series H Preferred Stock
          shall be calculated on the basis of a 360-day year

          holders of record of the Series E Preferred Stock and the
          Series H Preferred Stock at the close of business on the
          date specified by the Board of Directors of the Company;
          provided, however, that no such record date shall be more
          than thirty (30) days nor less than ten (10) days prior
          to the respective Dividend Payment Date.  Dividends on
          shares of Series E Preferred Stock and the Series H
          Preferred Stock shall accrue from the date of original
          issue of the shares of Series C Preferred Stock in
          exchange for which such shares of Series E Preferred
          Stock and Series H Preferred Stock were issued.  Such
          dividends will accrue whether or not they have been
          declared and whether or not there are profits, surplus or
          other funds of the Company legally available for the
          payment of dividends.  The date on which the Company
          originally issues any share of Series E Preferred Stock
          or Series H Preferred Stock will be deemed to be its
          "date of original issue" regardless of the number of
          times transfer of such share is made on the stock records
          maintained by or for the Company.

                    1.2.4.  All dividends paid or added to Stated
          Value, as the case may be, with respect to shares of the
          Series E Preferred Stock or Series H Preferred Stock
          shall be paid or added to Stated Value, as the case may
          be, ratably (based on the respective Stated Values plus
          Unpaid Dividends of the Series E Preferred Stock and the
          Series H Preferred Stock) with respect to such shares to
          the holders of Series E Preferred Stock and Series H
          Preferred Stock entitled thereto.

                    1.2.5.  So long as any shares of the Series E
          Preferred Stock or Series H Preferred Stock are
          outstanding, the Company shall not declare, pay or set
          apart for payment any dividend or other distribution on
          any of the Company's Common Stock, or Preferred Stock
          (other than the Series F Preferred Stock, the Series G
          Preferred Stock, the Series E Preferred Stock and the
          Series H Preferred Stock) or make any payment on account
          of, or set apart for payment money for a sinking fund or
          other similar fund for the purchase, redemption or other
          retirement of, any of the Common Stock, or Preferred
          Stock (other than the Series F Preferred Stock, the
          Series G Preferred Stock, the Series E Preferred Stock
          and the Series H Preferred Stock) or any warrants,
          rights, calls or options exercisable for any of the
          Common Stock or make any distribution in respect thereof,
          either directly or indirectly, and whether in cash,
          obligations or shares of the Company or other property
          (other than distributions or dividends in stock to the
          holders of such stock), and shall not permit any Person
          directly or indirectly controlled by the Company to
          purchase or redeem any of the Common Stock or Preferred
          Stock (other than the Series F Preferred Stock, the
          Series G Preferred Stock, the Series E Preferred Stock
          and the Series H Preferred Stock) or any warrants,
          rights, calls or options exercisable for any of the
          Common Stock, unless prior to or concurrently with such
          declaration, payment, setting apart for payment, purchase
          or distribution, as the case may be, all funds then
          required for the mandatory redemption of shares of the
          Series E Preferred Stock and the Series H Preferred Stock
          pursuant to Section 1.5.2 hereof, shall have been paid or
          be paid, and all Unpaid Dividends on shares of the Series
          E Preferred Stock and the Series H Preferred Stock not
          paid in cash, shall have been paid in cash or be paid in
          cash.  Notwithstanding the foregoing, the Company may
          declare and pay cash dividends on the Common Stock
          provided that (a) the Company is not then in default with
          respect to any of its obligations to pay dividends on the
          Series E Preferred Stock and the Series H Preferred
          Stock, (b) cash dividends on Common Stock during any
          fiscal year of the Company do not exceed twenty percent
          (20%) of the after-tax earnings per share of Common Stock
          for the immediately preceding fiscal year of the Company
          and (c) all Unpaid Dividends on the Series E Preferred
          Stock and the Series H Preferred Stock shall be paid in
          cash concurrently with the payment of such cash dividend
          on the Common Stock.  Notwithstanding the foregoing, the
          Company many declare and pay dividends in the form of
          Common Stock (with fractional shares to be paid in cash)
          pursuant to the terms of the Series D Preferred Stock.
                                         
                    1.3.  Rights on Liquidation, Dissolution or
          Winding-Up.

                    1.3.1.  In the event of any liquidation,
          dissolution or winding-up of the Company (including,
          without limitation, a liquidation or reorganization under
          Chapter 7 or 11 of Title 11 of the United States Code, as
          amended), after payment in full of all amounts due to the
          holders of Series F Preferred Stock and Series G
          Preferred Stock, the holders of shares of the Series A
          Preferred Stock, the Series E Preferred Stock and the
          Series H Preferred Stock then issued and outstanding
          shall be entitled to be paid out of the assets of the
          Company available for distribution to its stockholders,
          before any payment shall be made to the holders of Series
          B Preferred Stock, Series D Preferred Stock, Common Stock
          or of shares of any other class or series of stock of the
          Company (other than the Series F Preferred Stock and
          Series G Preferred Stock), an amount equal to the Stated
          Value per share, plus an amount equal to any Unpaid
          Dividends to and including the date of distribution with
          respect to such shares.  If, upon any liquidation,
          dissolution or winding-up of the Company (including,
          without limitation, a liquidation or reorganization under
          Chapter 7 or 11 of Title 11 of the United States Code, as
          amended), the assets of the Company available for
          distribution to its stockholders shall, after payment in
          full of all amounts due the holders of Series F Preferred
          Stock and Series G Preferred Stock, be insufficient (a
          "Liquidation Insufficiency") to pay the holders of shares
          of the Series A Preferred Stock, the Series E Preferred
          Stock and the Series H Preferred Stock the full amounts
          to which they shall respectively be entitled, the holders
          of shares of the Series A Preferred Stock, the Series E
          Preferred Stock and the Series H Preferred Stock shall be
          entitled to receive all the assets of the Company
          available for distribution and each such holder of shares
          of the Series A Preferred Stock, the Series E Preferred
          Stock and the Series H Preferred Stock shall share in any
          distribution in the proportion which the aggregate Stated
          Values of the shares of the Series A Preferred Stock
          (plus all Unpaid Dividends thereon), the Series E
          Preferred Stock (plus all Unpaid Dividends thereon) and
          the Series H Preferred Stock (plus all Unpaid Dividends
          thereon) held by such holder of the Series A Preferred
          Stock, Series E Preferred Stock or Series H Preferred
          Stock bears to the aggregate Stated Values of all shares
          of the Series A Preferred Stock (plus all Unpaid
          Dividends thereon), Series E Preferred Stock (plus all
          Unpaid Dividends thereon) and the Series H Preferred
          Stock (plus all Unpaid Dividends thereon) then
          outstanding.  If there is no Liquidation Insufficiency
          and payment shall have been made to the holders of shares
          of the Series A Preferred Stock, Series E Preferred Stock
          and Series H Preferred Stock of the full amount to which
          they shall be entitled, then the holders of shares of the
          Series A Preferred Stock, Series E Preferred Stock and
          Series H Preferred Stock shall be entitled to receive no
          further distributions thereon and the holders of shares
          of the Series B Preferred Stock shall be entitled to
          receive an amount equal to the Stated Value (plus all
          Unpaid Dividends thereon) per share thereof.  After
          payment shall have been made to the holders of shares of
          the Series B Preferred Stock of the full amounts to which
          they shall be entitled, the holders of shares of the
          Common Stock and of shares of any other class of stock of
          the Company, if any, shall be entitled to share,
          according to their respective rights and preferences, in
          all remaining assets of the Company available for
          distribution to its stockholders.

                    1.4.  Voting Power.

                    1.4.1.  Except as otherwise expressly provided
          herein or as required by law, (i) each holder of 
          Series H Preferred Stock shall be entitled to vote on all
          matters as to which stockholders of the Company are
          entitled to vote, and (ii) each holder of Series H
          Preferred Stock shall be entitled to cast a number of
          votes equal to the greatest number of whole shares of
          Common Stock into which such holder's shares of Series H
          Preferred Stock could be converted, pursuant to the
          provisions of Section 1.6 hereof, at the record date for
          the determination of stockholders entitled to vote on
          such matter or, if no such record date is established, at
          the date such vote is taken or any written consent of
          stockholders is solicited.  Except as otherwise expressly
          provided herein or as required by law, the holders of
          shares of Series B Preferred Stock, Series D Preferred
          Stock, Series E Preferred Stock, Series F Preferred
          Stock, Series G Preferred Stock, Series H Preferred Stock
          and Common Stock shall be entitled to vote together as a
          class with respect to all matters as to which such
          stockholders of the Company are entitled to vote.

                    1.4.2.  The holders of Series E Preferred Stock
          and Series H Preferred Stock shall have the right, voting
          together separately as a single class, to elect two (2)
          directors to the Board of Directors of the Company,
          which, unless increased pursuant to the Special Voting
          Rights, shall be composed of no more than ten (10)
          directors.

                    1.4.3.  In the event that at any time there
          shall occur a Two-Dividend Default, then immediately upon
          the happening of such Two-Dividend Default and until such
          Two-Dividend Default and all defaults in the payment of
          quarterly dividends on the Series E Preferred Stock and
          Series H Preferred Stock subsequent to and occurring
          while such Two-Dividend Default exists shall be cured,
          the number of directors constituting the Board of
          Directors of the Company shall, without further action,
          be increased by two and the holders of Series E Preferred
          Stock and Series H Preferred Stock shall have, in
          addition to the other voting rights set forth herein, the
          exclusive right, voting separately as a class, to elect
          two directors of the Company to fill such newly created
          directorship, the remaining directors to be elected by
          the class or classes of stock (including the Series E
          Preferred Stock and the Series H Preferred Stock)
          entitled to vote therefor, at each meeting of
          stockholders held for the purpose of electing directors. 
          In the event that at any time there shall occur a Four-
          Dividend Default or a Lender Default, then immediately on
          the happening of such Four-Dividend Default or Lender
          Default and until such Lender Default or Four-Dividend
          Default and all defaults in the payment of quarterly
          dividends on the Series E Preferred Stock subsequent to
          and occurring while such Four-Dividend Default exists
          shall be cured, then the number of directors constituting
          the Board of Directors of the Company shall, without
          further action, be further increased by six (in the case
          of a Four-Dividend Default) or by eight (in the case of a
          Lender Default) and the holders of Series E Preferred
          Stock and the Series H Preferred Stock shall have, in
          addition to the other voting rights set forth herein, the
          exclusive right, voting separately as a class, to elect
          directors of the Company to fill such newly created
          directorships, the remaining directors to be elected by
          the class or classes of stock (including the Series E
          Preferred Stock and the Series H Preferred Stock)
          entitled to vote therefor, at each meeting of
          stockholders held for the purpose of electing directors. 
          During the existence of a Four Dividend Default, a
          majority of the Directors not elected by the holders of
          the Series E Preferred Stock and the Series H Preferred
          Stock (or their affiliates) shall have the right to
          declare and pay dividends on the Series E Preferred Stock
          and the Series H Preferred Stock out of funds legally
          available for the payment of such dividends. 
          Notwithstanding the foregoing provisions of this Section
          1.4.3, upon payment in full of all quarterly dividends on
          the Series E Preferred Stock and the Series H Preferred
          Stock coming due subsequent to a Four-Dividend Default
          and the dividend which resulted in the Four-Dividend
          Default, so that no more than three consecutive quarterly
          dividends on the Series E Preferred Stock and the Series
          H Preferred Stock remain in default, the Special Series H
          Voting Rights of the holders of Series E Preferred Stock
          and the Series H Preferred Stock shall be reduced so that
          they have the right, voting separately as a class, to
          elect two Additional Directors of the Company. 
          Notwithstanding the foregoing provisions of this Section
          1.4.3, upon payment in full of (i) all quarterly
          dividends on the Series E Preferred Stock and the Series
          H Preferred Stock coming due subsequent to a Two-Dividend
          Default and the dividend which resulted in the Two-
          Dividend Default, or (ii) upon payment in full of all
          quarterly dividends on the Series E Preferred Stock and
          the Series H Preferred Stock coming due subsequent to a
          Four-Dividend Default and three of the dividends which
          resulted in a Four-Dividend Default, so that, in each
          case, no more than one quarterly dividend remains in
          default, or (iii) upon payment in full or cure of all
          Lender Defaults, the Special Series H Voting Rights shall
          terminate.  Upon any termination of the aforesaid Special
          Series H Voting Rights, the term of office of each
          director elected by the holders of the Series E Preferred
          Stock and the Series H Preferred Stock pursuant to this
          Section 1.4.3 then in office shall thereupon terminate
          and upon such termination the number of directors
          constituting the Board of Directors shall, by resolution
          of the Board of Directors, be reduced accordingly,
          subject always to the subsequent increase of the number
          of directors from time to time pursuant to this Section
          1.4.3 in the event of the periodic future vesting of the
          right of the holders of the Series E Preferred Stock and
          Series H Preferred Stock to elect Additional Directors. 
          The term of office of any director elected by the holders
          of the Series E Preferred Stock and Series H Preferred
          Stock pursuant to this Section 1.4.3 shall terminate upon
          the earlier of the termination of the Special Series H
          Voting Rights and the election of a successor to such
          director at any meeting of holders of the Series E
          Preferred Stock and the Series H Preferred Stock for the
          purpose of electing directors.

                    1.4.4.  Special Series H Voting Rights may be
          exercised either at a special meeting of holders of the
          Series E Preferred Stock and the Series H Preferred
          Stock, or at any annual or special meeting of
          stockholders of the Company, or may be exercised by the
          written consent of holders of the Series E Preferred
          Stock and the Series H Preferred Stock pursuant to the
          Delaware General Corporation Law.

                    1.4.5.  At any time when Special Series H
          Voting Rights pursuant to Section 1.4.3 above shall have
          vested in holders of the Series E Preferred Stock and the
          Series H Preferred Stock, and if such rights shall have
          not already been initially exercised, a proper officer of
          the Company shall, upon the written request of any holder
          of record of the Series E Preferred Stock or Series H
          Preferred Stock then outstanding, addressed to the
          secretary of the Company, call a special meeting of
          holders of the Series E Preferred Stock and Series H
          Preferred Stock for the purpose of electing directors. 
          Such meeting shall be held at the earliest practicable
          date upon the notice required for annual meetings of the
          stockholders at the place for holding annual meetings of
          the stockholders of the Company or, if none, at a place
          designated by the secretary of the Company.  If such a
          meeting shall not be called by the proper officer of the
          Company within ten (10) days after the personal service
          of such written request upon the secretary of the
          Company, or within ten (10) days after mailing the same
          within the United States, by first-class registered mail,
          addressed to the secretary of the Company at the
          Company's principal office (such mailing to be evidenced
          by registry receipt issued by the postal authorities),
          then the holders of record of ten percent (10%) of the
          shares of the Series E Preferred Stock or the Series H
          Preferred Stock then outstanding may designate in writing
          a holder of Series E Preferred Stock or Series H
          Preferred Stock to call such meeting at the expense of
          the Company, and such meeting may be called by such
          person so designated upon the notice required for annual
          meetings of stockholders and shall be held at the same
          place as is elsewhere provided in this Section 1.4.5. 
          Any holder of Series E Preferred Stock or Series H
          Preferred Stock shall have access to the stock books of
          the Company for the purpose of causing a meeting of
          holders of Series E Preferred Stock and Series H
          Preferred Stock to be called pursuant to the provisions
          hereof.

                    1.4.6.  At any meeting held for the purpose of
          electing directors at which the holders of Series E
          Preferred Stock and Series H Preferred Stock shall have
          the right to elect directors as provided herein, the
          presence in person or by proxy of the holders of twenty-
          five percent (25%) of the then outstanding shares of
          Series E Preferred Stock and Series H Preferred Stock
          shall be required and shall be sufficient to constitute a
          quorum of such class for the election of directors by
          such class.  In the absence of a quorum of the holders of
          Series E Preferred Stock and Series H Preferred Stock
          entitled to vote for the election of directors, a
          majority of the holders present in person or by proxy of
          such class shall have the power to adjourn the meeting
          for the election of directors which the holders of such
          class are entitled to elect, from time to time, without
          notice other than announcement at the meeting, until a
          quorum shall be present.

                    1.4.7.  Unless the vote of the holders of a
          greater number of shares of this Series H Preferred Stock
          shall then be required by law, the consent of the holders
          of at least 66-2/3% of all of the shares of this Series H
          Preferred Stock at the time outstanding, voting together
          as a separate class, shall be necessary for authorizing,
          effecting or validating any of the following:

                    (a)  the creation, authorization or issue of
          any shares of any class or series of stock of the Company
          ranking prior to, or pari passu with, the shares of this
          Series H Preferred Stock as to dividends or upon
          liquidation or otherwise, or the reclassification of any
          authorized stock of the Company into any such prior
          shares, or the creation, authorization or issue of any
          obligation or security convertible into or evidencing the
          right to purchase any such prior shares; and 

                    (b)  the amendment, alteration or repeal of any
          of the provisions of the Certificate of Incorporation or
          of any certificate amendatory thereof or supplemental
          thereto so as to affect adversely the preferences,
          rights, powers or privileges of this Series H Preferred
          Stock;

                    1.5.  Redemption.

                    1.5.1.  Optional Redemption.  On or after  
          August 1, 1995, the Company shall have the right to
          redeem all or part of the Series H Preferred Stock upon
          not less than ten (10) days prior written notice to the
          holders of the Series H Preferred Stock.

                    No shares of Series H Preferred Stock shall be
          redeemed pursuant to this Section 1.5.1 unless
          concurrently therewith shares of Series E Preferred Stock
          are redeemed on a pro rata basis (based on the respective
          Stated Values plus Unpaid Dividends of the Series H
          Preferred Stock and the Series E Preferred Stock) and no
          shares of Series E Preferred Stock shall be redeemed
          unless concurrently therewith shares of Series H
          Preferred Stock are redeemed on a pro rata basis (based
          on the respective Stated Values plus Unpaid Dividends of
          the Series H Preferred Stock and the Series E Preferred
          Stock).

                    In the event of optional redemption by the
          Company within sixty days following any occurrence of a
          Book Value Event or in the event of optional redemption
          by the Company after December 31, 2004, shares of Series
          E Preferred Stock and Series H Preferred Stock shall be
          redeemed at a redemption price equal to the Stated Value
          per share, plus all Unpaid Dividends payable with respect
          to such shares as of the date fixed for redemption,
          without interest.  In the event of optional redemption by
          the Company prior to January 1, 2005 in the absence of
          the existence of a Book Value Event, shares of Series E
          Preferred Stock and Series H Preferred Stock shall be
          redeemed at a redemption price equal to 107% of the
          Stated Value per share, plus all Unpaid Dividends payable
          with respect to such shares as of the date fixed for
          redemption without interest.  In either circumstance,
          such redemption price shall be paid in cash.

                    1.5.2.  Mandatory Redemption.  The Company
          shall redeem all (but not less than all) shares of Series
          E Preferred Stock and Series H Preferred Stock on August
          1, 2004 (the "Mandatory Redemption Date") at a cash
          redemption price equal to the Stated Value per share of
          such Series E Preferred Stock and Series H Preferred
          Stock, plus all Unpaid Dividends on each such share up to
          and including the date of redemption.

          Payment shall be applied to the redemption of the shares
          of Series E Preferred Stock and Series H Preferred Stock,
          pro rata (based on the respective Stated Values plus
          Unpaid Dividends)  among the holders of all outstanding
          shares of the Series E Preferred Stock and Series H
          Preferred Stock on the Mandatory Redemption Date and
          shall be paid to each such holder upon surrender of the
          certificate or certificates evidencing such shares to be
          redeemed to the secretary of the Company.  If the Company
          fails to redeem all outstanding shares of Series E
          Preferred Stock and Series H Preferred Stock on the
          Mandatory Redemption Date, then the other terms of the
          Series E Preferred Stock and Series H Preferred Stock
          shall remain in full force and effect and the holder
          shall have no further recourse against the Company.

                     1.5.3.  Special Redemption.  (a)  Upon the
          occurrence of any Special Redemption Event (as
          hereinafter defined, each holder of Series E Preferred
          Stock and Series H Preferred Stock shall have the right
          to require that the Company redeem, to the extent the
          Company lawfully may do so, all or a portion of the
          shares of Series E Preferred Stock and Series H Preferred
          Stock held by such holder, at a redemption price in cash
          equal to the Stated Value per share (plus all Unpaid
          Dividends thereon to the redemption date).  No shares of
          Series H Preferred Stock shall be redeemed pursuant to
          this Section 1.5.3 unless concurrently therewith shares
          of Series E Preferred Stock are redeemed on a pro rata
          basis (based on the respective Stated Values plus Unpaid
          Dividends of the Series E Preferred Stock and the Series
          H Preferred Stock) and no shares of Series H Preferred
          Stock shall be redeemed pursuant to this Section 1.5.3
          unless concurrently therewith shares of Series E
          Preferred Stock are redeemed on a pro rata basis (based
          on the respective Stated Values plus Unpaid Dividends of
          the Series E Preferred Stock and the Series H Preferred
          Stock).

                     (b)  Within five Business Days following any
          Special Redemption Event (as hereinafter defined), the
          Company will mail to each holder of Series E Preferred
          Stock and Series H Preferred Stock a notice (the "Special
          Redemption Event Notice") (i) stating that a Special
          Redemption Event has occurred; (ii) setting forth a
          purchase date (the "Special Redemption  Date"), which
          shall be no earlier than 20 Business Days nor later than
          30 Business Days from the date the Special Redemption
          Event Notice is mailed; (iii) setting forth the
          Conversion Price then in effect with respect to such
          shares of Series E Preferred Stock and Series H Preferred
          Stock, pursuant to the provisions of Section 1.6 hereof;
          and (iv) setting forth the instructions reasonably
          determined by the Company, consistent with this Section
          1.5.3 and applicable law, that a holder must follow in
          order to require the redemption of his Series E Preferred
          Stock and Series H Preferred Stock.  Holders of Series E
          Preferred Stock and Series H Preferred Stock seeking to
          require that the Company redeem their shares will be
          required to surrender their shares to the Company prior
          to the close of business on the third Business Day prior
          to the Special Redemption Date.

                     (c)  Immediately prior to the redemption of
          any shares of Series E Preferred Stock and Series H
          Preferred Stock pursuant to this Section 1.5.3., the
          Company shall declare and pay a cash dividend on all
          outstanding shares of Series E Preferred Stock and Series
          H Preferred Stock in an amount equal to the aggregate
          amount of all accumulated and unpaid dividends that have
          been added to the Stated Value thereof and all accrued
          Unpaid Dividends thereon to the Special Redemption Date. 
          Upon the Special Redemption Date, the redemption price of
          such shares shall be payable to the order of the person
          whose name appears on the certificate or certificates
          representing such shares as the owner thereof and each
          surrendered certificate shall be cancelled.  From and
          after the date the Company shall irrevocably deposit an
          amount equal to the redemption price of the shares of
          Series E Preferred Stock and Series H Preferred Stock to
          be redeemed in trust for the holders of such shares with
          a bank having capital and surplus in excess of $100
          million, which bank shall be named in the Special
          Redemption Event Notice, all rights of the holders of
          such Series E Preferred Stock and Series H Preferred
          Stock, except the right to receive such redemption price
          without interest upon surrender of their certificate or
          certificates, shall cease with respect to such shares,
          and such shares shall not thereafter be transferred on
          the books of the Company or be deemed to be outstanding
          for any purpose whatsoever. 

                     (d)  "Special Redemption Event" shall mean:

                     (i)  consummation of any merger,
                  reorganization or consolidation
                  transaction involving the Company;

                     (ii) the acquisition by purchase or
                  otherwise of a controlling interest in the
                  business or assets of, or the stock or
                  other evidence of beneficial ownership of,
                  any other Person if consummation of such
                  transaction results in a transfer of
                  ownership of a majority of the voting
                  securities of the Company to such other
                  Person or its stockholders;

                     (iii) the sale, lease, conveyance,
                  transfer, exchange, encumbrance or other
                  disposition, in one transaction or a
                  series of related transactions, of more
                  than 25% of the assets of the Company;
                  provided, however, that a definitive
                  agreement between the Company and a party
                  with which it is currently negotiating
                  that contemplates an ongoing revenue
                  stream to the Company based on commercial
                  exploitation of the Company's technology
                  and requiring a payment to the Company
                  upon execution of at least $1.25 million,
                  such payment to be not primarily in
                  consideration of any requirement that the
                  Company render services, shall not be
                  deemed to breach this provision if such
                  agreement is executed on or before July
                  31, 1996; or

                     (iv)  the sale or other disposition of
                  voting securities of the Company, in a
                  transaction or a series of related
                  transactions, if consummation of such
                  transaction or transactions results in a
                  transfer of ownership of a majority of the
                  voting securities of the Company.

                    1.5.4.  With respect to any optional redemption
          of Series H Preferred Stock, each redemption of Series H
          Preferred Stock shall be made so that the number of
          shares of Series H   Preferred Stock held by each
          registered holder thereof shall be reduced in an amount
          which shall bear the same ratio to the total number of
          shares of Series H Preferred Stock being so redeemed as
          the number of shares of Series H Preferred Stock then
          held by such holder bears to the aggregate number of
          shares of Series H Preferred Stock then outstanding.

                    1.5.5.  Except as otherwise provided herein, at
          least twenty (20) days before any Redemption Date (ten
          (10) days if such redemption is in connection with a Book
          Value Event), a Redemption Notice shall be mailed,
          postage prepaid, to each holder of record of the Series E
          Preferred Stock and Series H Preferred Stock which is to
          be redeemed, at its address shown on the records of the
          Company; provided, however, that the Company's failure to
          give such Redemption Notice shall in no way affect its
          obligation to redeem the shares of Series E Preferred
          Stock and Series H Preferred Stock as provided herein. 
          The Redemption Notice shall set forth:

                    (i)  the number of shares of Series H
               Preferred  Stock held by the holder which shall
               be redeemed by the Company, and the total
               number of shares of Series E Preferred Stock
               and Series H Preferred Stock held by all
               holders of such series to be so redeemed;

                    (ii)  the Redemption Date and the
               redemption price;

                    (iii)  that the holder is to surrender to
               the Company, at the place designated therein,
               its certificate or certificates representing
               the shares of Series E Preferred Stock and
               Series H Preferred Stock to be redeemed;

                    (iv)  the Conversion Price then in effect
               with respect to such shares of Preferred Stock,
               pursuant to the provisions of Section 1.6
               hereof; and

                    (v)  that the conversion rights of shares
               of Series E Preferred Stock and Series H
               Preferred Stock to be redeemed shall terminate
               at the close of business on the date prior to
               the Redemption Date.

                    1.5.6.  Each holder of shares of Series E
          Preferred Stock and Series H Preferred Stock to be
          redeemed shall surrender the certificate or certificates
          representing such shares to the Company at the place
          designated in the Redemption Notice and thereupon the
          applicable redemption price for such shares shall be paid
          to the order of the Person whose name appears on such
          certificate or certificates and each surrendered
          certificate shall be cancelled and retired.

                    1.5.7.  From and after the Redemption Date, no
          shares of Series E Preferred Stock and Series H Preferred
          Stock thereupon subject to redemption shall be entitled
          to any further accrual of any dividends pursuant to
          Section 1.2 hereof or to the conversion provisions set
          forth in Section 1.6 hereof; provided, however, that
          sufficient funds for payment of the redemption price for
          the shares of Series E Preferred Stock and Series H
          Preferred Stock to be redeemed are deposited or held and
          set apart for that purpose at the place of payment on or
          prior to the Redemption Date.

                    1.5.8.  If the Redemption Notice shall have
          been mailed as provided herein, and if on or before the
          Redemption Date specified in such notice the
          consideration necessary for such redemption shall have
          been set apart so as to be available therefor, then on
          and after the close of business on the Redemption Date
          the shares of Series E Preferred Stock and Series H
          Preferred Stock called for redemption, notwithstanding
          that any certificate therefor shall not have been
          surrendered for cancellation, shall no longer be deemed
          outstanding, and all rights with respect to such shares
          shall forthwith cease and terminate, except only the
          right of the holders thereof to receive upon surrender of
          their certificates the consideration payable upon
          redemption thereof.  In case fewer than all the shares
          represented by any such certificate are redeemed, a new
          certificate shall be issued representing the unredeemed
          shares without cost to the holder thereof.

                    1.6.  Conversion Rights.

                    1.6.1.  Each holder of the shares of Series H
          Preferred Stock shall have the right, at the election of
          such holder, exercised at any time and from time to time,
          to convert, subject to the terms and provisions hereof,
          all or any portion of such shares of Series H Preferred
          Stock into fully paid and non-assessable shares of Common
          Stock of the Company or any capital stock or other
          securities into which such Common Stock shall have been
          changed or any capital stock or other securities
          resulting from a reclassification thereof.  Such
          conversion of Series H Preferred Stock to shares of
          Common Stock shall be made at the Conversion Price,
          subject to adjustment from time to time as set forth
          herein.  Series H Preferred Stock may be converted by the
          holder thereof during normal business hours on any
          Business Day by surrender of the required number of
          shares of Series H Preferred Stock, accompanied by
          written evidence of the holder's election to convert such
          holder's Series H Preferred Stock or portion thereof, to
          the Company at its principal executive offices.  Payment
          of the Conversion Price for the shares of Common Stock
          specified in such election shall be made by applying
          shares of Series H Preferred Stock, valued at the Stated
          Value per share.  Payment of Unpaid Dividends, if any,
          applicable to such converted shares of Series H Preferred
          Stock shall be made in accordance with Section 1.6.5.

                    1.6.2.  All or part of the outstanding shares
          of Series H Preferred Stock shall, at the option of the
          Company and upon written notice to the holders thereof
          given not less than ten (10) days prior to the Closing of
          a Triggering Event be converted, by applying shares of
          Series H Preferred Stock valued at the Stated Value per
          share, as of the date and time of the Closing into shares
          of Common Stock at the Conversion Price automatically and
          without any further action by the holders of such shares
          and whether or not the certificates representing such
          shares are surrendered to the Company or its transfer
          agent.  Payment of Unpaid Dividends, if any, applicable
          to such converted shares of Series H Preferred Stock
          shall be made in accordance with Section 1.6.5.

                    1.6.3.  Upon the conversion of Series H
          Preferred Stock, the holders of such Series H Preferred
          Stock shall surrender the certificates representing such
          shares at the office of the Company.  The Company shall
          not be obligated to issue certificates evidencing the
          shares of Common Stock issuable upon such conversion (or
          to pay any Unpaid Dividends in connection with such
          conversion) unless certificates evidencing such shares of
          Series H Preferred Stock being converted are either
          delivered to the Company or the holder notifies the
          Company that such certificates have been lost, stolen, or
          destroyed and delivers to the Company an agreement
          satisfactory to the Company to indemnify the Company from
          any loss incurred by it in connection therewith.

                    1.6.4.  Each conversion of Series H Preferred
          Stock shall be deemed to have been effected immediately
          prior to the close of business on the Business Day on
          which such Series H Preferred Stock shall have been
          surrendered to the Company as provided herein (except
          that if such conversion is in connection with a
          Triggering Event, then such conversion shall be deemed to
          have been effected concurrently with the Closing of such
          Triggering Event), and such conversion shall be at the
          Conversion Price in effect at such time.  On each such
          day that the conversion of shares of Series H Preferred
          Stock is deemed effected, the person or persons in whose
          name or names any certificate or certificates for shares
          of Common Stock are issuable upon such conversion shall
          be deemed to have become the holder or holders of record
          thereof.

                    1.6.5.   As promptly as practical after the
          conversion of shares of Series H Preferred Stock, in
          whole or in part, and in any event within five (5)
          Business Days thereafter (unless such conversion is in
          connection with a Triggering Event, in which event
          concurrently with such conversion), the Company at its
          expense (including the payment by it of any applicable
          issue, stamp or other taxes, other than any income taxes
          and other than any taxes arising by reason of issuance of
          shares of Common Stock to any person other than such
          holder) will cause to be issued in the name of and
          delivered to the holder thereof or as such holder may
          direct, (i) a certificate or certificates for the number
          of shares of Common Stock to which such holder shall be
          entitled upon such conversion plus, in lieu of any
          fractional shares to which such holder would otherwise be
          entitled, cash in an amount equal to the same fraction of
          the Current Market Price per share of Common Stock and
          (ii) Unpaid Dividends, if any, applicable as of the time
          of conversion to those shares of Preferred Stock which
          are converted.  Such Unpaid Dividends shall be paid in
          cash, without interest.  In case fewer than all the
          shares of Series H Preferred Stock represented by any
          surrendered certificate are converted into Common Stock,
          a new certificate representing the shares of Series H
          Preferred Stock not converted shall be issued without
          cost to the holder thereof. 


                    1.7.  Anti-Dilution Adjustments.  The number of
          shares of Common Stock issuable upon any conversion
          provided for in Section 1.6 shall be subject to
          adjustment, from time to time, in accordance with the
          following provisions:

                    1.7.1.  Issuance of Additional Shares of Common
          Stock.  In case the Company at any time or from time to
          time after the date hereof shall issue or sell Additional
          Shares of Common Stock (including Additional Shares of
          Common Stock deemed to be issued pursuant to Section
          1.7.3 or 1.7.4) without consideration or for a
          consideration per share less than the Conversion Price in
          effect immediately prior to such issue or sale, then, in
          each such case, subject to Section 1.7.8, such Conversion
          Price shall be reduced, concurrently with such issue or
          sale, to a price (calculated to the nearest .001 of a
          cent) determined by multiplying such Conversion Price by
          a fraction

                    (a)  the numerator of which shall be (i)
               the number of shares of Common Stock
               outstanding immediately prior to such issue or
               sale plus (ii) the number of shares of Common
               Stock which the aggregate consideration
               received by the Company for the total number of
               such Additional Shares of Common Stock so
               issued or sold would purchase at such
               Conversion Price, and

                    (b)  the denominator of which shall be the
               number of shares of Common Stock outstanding
               immediately after such issue or sale,

          provided that, for the purposes of this Section 1.7.1,
          (x) immediately after any Additional Shares of Common
          Stock are deemed to have been issued pursuant to Section
          1.7.3 or 1.7.4, such Additional Shares shall be deemed to
          be outstanding and (y) treasury shares shall not be
          deemed to be outstanding.

                    1.7.2.  Adjustment of Conversion Price Upon
          Extraordinary Dividends and Distributions.  In case the
          Company at any time or from time to time after the date
          hereof shall declare, order, pay or make a dividend or
          other distribution (including, without limitation, any
          distribution of other or additional stock or other
          securities or property or Options by way of dividend or
          spin-off, reclassification, recapitalization or similar
          corporate rearrangement) on the Common Stock, other than
          (a) a dividend payable in Additional Shares of Common
          Stock or (b) a cash dividend permitted pursuant to
          Section 1.2.5 hereof, then, and in each such case,
          subject to Section 1.7.8, the Conversion Price in effect
          immediately prior to the close of business on the record
          date fixed for the determination of holders of any class
          of securities entitled to receive such dividend or
          distribution shall be reduced, effective as of the close
          of business on such record date, to a price (calculated
          to the nearest .001 of a cent) determined by multiplying
          such Conversion Price by a fraction

                    (a)  the numerator of which shall be the
               Current Market Price in effect on such record
               date or, if the Common Stock trades on an ex-
               dividend basis, on the date prior to the
               commencement of ex-dividend trading, less the
               amount of such dividend or distribution (as
               determined in good faith by the Board of
               Directors of the Company) applicable to one
               share of Common Stock,

                    (b)  the denominator of which shall be
               such Current Market Price, 

          provided that, in the event that the amount of such
          dividend as so determined is equal to or greater than 25%
          of such Current Market Price or in the event that such
          fraction is less than three fourths (3/4), in lieu of the
          foregoing adjustment, adequate provision shall be made so
          that the holders of the Series H Preferred Stock shall
          receive, in the same form and at the same time such
          dividend is payable to holders of Common Stock, a pro
          rata share of such dividend based upon the maximum number
          of shares of Common Stock at the time issuable to such
          holders upon conversion of such Series H Preferred Stock.

                    1.7.3.  Treatment of Options and Convertible
          Securities.  In case the Company at any time or from time
          to time after the date hereof shall issue, sell, grant or
          assume, or shall fix a record date for the determination
          of holders of any class of securities entitled to
          receive, any Options or Convertible Securities, then and
          in each such case, the maximum number of Additional
          Shares of Common Stock (as set forth in the instrument
          relating thereto, without regard to any provisions
          contained therein for a subsequent adjustment of such
          number) issuable upon the exercise of such Options or, in
          the case of Convertible Securities and Options therefor,
          the conversion or exchange of such Convertible
          Securities, shall be deemed to be Additional Shares of
          Common Stock issued as of the time of such issue, sale,
          grant or assumption or, in case such a record date shall
          have been fixed, as of the close of business on such
          record date (or, if the Common Stock trades on an ex-
          dividend basis, on the date prior to the commencement of
          ex-dividend trading), provided that such Additional
          Shares of Common Stock shall not be deemed to have been
          issued unless the consideration per share (determined
          pursuant to Section 1.7.5) of such shares would be less
          than the Conversion Price in effect on the date of and
          immediately prior to such issue, sale, grant or
          assumption or immediately prior to the close of business
          on such record date (or, if the Common Stock trades on an
          ex-dividend basis, on the date prior to the commencement
          of ex-dividend trading), as the case may be, and
          provided, further, that in any such case in which
          Additional Shares of Common Stock are deemed to be issued

                    (a)  no further adjustment of the
               Conversion Price shall be made upon the
               subsequent issue or sale of Convertible
               Securities or shares of Common Stock upon the
               exercise of such Options or the conversion or
               exchange of such Convertible Securities;

                    (b)  if such Options or Convertible
               Securities by their terms provide, with the
               passage of time or otherwise, for any increase
               in the consideration payable to the Company, or
               decrease in the number of Additional Shares of
               Common Stock issuable, upon the exercise,
               conversion or exchange thereof (by change of
               rate or otherwise), the Conversion Price
               computed upon the original issue, sale, grant
               or assumption thereof (or upon the occurrence
               of the record date, or date prior to the
               commencement of ex-dividend trading, as the
               case may be, with respect thereto), and any
               subsequent adjustments based thereon, shall,
               upon any such increase or decrease becoming
               effective, be recomputed to reflect such
               increase or decrease insofar as it affects such
               Options, or the rights of conversion or
               exchange under such Convertible Securities,
               which are outstanding at such time;

                    (c)  upon the expiration (or purchase by
               the Company and cancellation or retirement) of
               any such Options which shall not have been
               exercised or the expiration of any rights of
               conversion or exchange under any such
               Convertible Securities which shall not have
               been exercised (or purchase by the Company and
               cancellation or retirement of any such
               Convertible Securities the rights of conversion
               or exchange under which shall not have been
               exercised), the Conversion Price computed upon
               the original issue, sale, grant or assumption
               (or upon the occurrence of the record date, or
               date prior to the commencement of ex-dividend
               trading, as the case may be, with respect
               thereto), and any subsequent adjustments based
               thereon, shall, upon such expiration (or such
               cancellation or retirement, as the case may
               be), be recomputed as if:

                    (i)  in the case of Options for Common
               Stock or Convertible Securities, the only
               Additional Shares of Common Stock issued or
               sold were the Additional Shares of Common
               Stock, if any, actually issued or sold upon the
               exercise of such Options or the conversion or
               exchange of such Convertible Securities and the
               consideration received therefor was the
               consideration actually received by the Company
               for the issue, sale, grant or assumption of all
               such Options, whether or not exercised, plus
               the consideration actually received by the
               Company upon such exercise, or for the issue or
               sale of all such Convertible Securities which
               were actually converted or exchanged, plus the
               additional consideration, if any, actually
               received by the Company upon such conversion or
               exchange, and

                    (ii)  in the case of Options for
               Convertible Securities, only the Convertible
               Securities, if any, actually issued or sold
               upon the exercise of such Options were issued
               at the time of the issue, sale, grant or
               assumption of such Options, and the
               consideration received by the Company for the
               Additional Shares of Common Stock deemed to
               have then been issued was the consideration
               actually received by the Company for the issue,
               sale, grant or assumption of all such Options,
               whether or not exercised, plus the
               consideration deemed to have been received by
               the Company (pursuant to Section 1.7.5) upon
               the issue or sale of such Convertible
               Securities with respect to which such Options
               were actually exercised;

                    (d)  no readjustment pursuant to
               subdivision (b) or (c) above shall have the
               effect of increasing the Conversion Price by an
               amount in excess of the amount of the
               adjustment thereof originally made in respect
               of the issue, sale, grant or assumption of such
               Options or Convertible Securities; and

                    (e)  in the case of any such Options which
               expire by their terms not more than thirty (30)
               days after the date of issue, sale, grant or
               assumption thereof, no adjustment of the
               Conversion Price shall be made until the
               expiration or exercise of all such Options,
               whereupon such adjustment shall be made in the
               manner provided in subdivision (c) above.

                    1.7.4.  Treatment of Stock Dividends, Stock
          Splits, etc.  In case the Company at any time or from
          time to time after the date hereof shall declare or pay
          any dividend on the Common Stock payable in Common Stock,
          or shall effect a subdivision of the outstanding shares
          of Common Stock into a greater number of shares of Common
          Stock (by reclassification or otherwise than by payment
          of a dividend in Common Stock), then, and in each such
          case, Additional Shares of Common Stock shall be deemed
          to have been issued (a) in the case of any such dividend,
          immediately after the close of business on the record
          date for the determination of holders of any class of
          securities entitled to receive such dividend, or (b) in
          the case of any such subdivision, at the close of
          business on the date immediately prior to the day upon
          which such corporate action becomes effective.

                    1.7.5.   Computation of Consideration.  For the
          purposes of this Section 1.7,

                    (a)  the consideration for the issue or
               sale of any Additional Shares of Common Stock
               shall, irrespective of the accounting treatment
               of such consideration,

                    (i)  insofar as it consists of cash, be
               computed at the net amount of cash received by
               the Company, without deducting any expenses
               paid or incurred by the Company or any
               commissions or compensation paid or concessions
               or discounts allowed to underwriters, dealers
               or others performing similar services in
               connection with such issue or sale,

                    (ii)  insofar as it consists of property
               (including securities) other than cash, be
               computed at the fair value thereof at the time
               of such issue or sale, as determined in good
               faith by the Board of Directors of the Company
               (subject to confirmation by a firm of
               independent certified public accountants of
               recognized standing approved by the holders of
               a majority of the Series E Preferred Stock and
               Series H Preferred Stock), and

                    (iii)  in case Additional Shares of Common
               Stock are issued or sold together with other
               stock or securities or other assets of the
               Company for a consideration which covers both,
               be the portion of such consideration so
               received, computed as provided in clauses (i)
               and (ii) above, allocable to such Additional
               Shares of Common Stock, all as determined in
               good faith by the Board of Directors of the
               Company (subject to confirmation by a firm of
               independent certified public accountants of
               recognized standing approved by the holders of
               a majority of the Series E Preferred Stock and
               Series H Preferred Stock);

                    (b)  Additional Shares of Common Stock
               deemed to have been issued pursuant to Section
               1.7.3, relating to Options and Convertible
               Securities, shall be deemed to have been issued
               for a consideration per share determined by
               dividing

                    (i)   the total amount, if any, received
               and receivable by the Company as consideration
               for the issue, sale, grant or assumption of the
               Options or Convertible Securities in question,
               plus the minimum aggregate amount of additional
               consideration (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such consideration to protect
               against dilution) payable to the Company upon
               the exercise in full of such Options or the
               conversion or exchange of such Convertible
               Securities or, in the case of Options for
               Convertible Securities, the exercise of such
               Options for Convertible Securities and the
               conversion or exchange of such Convertible
               Securities, in each case computing such
               consideration as provided in the foregoing
               subdivision (a),

          by

                    (ii)  the maximum number of shares of
               Common Stock (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such number to protect against
               dilution) issuable upon the exercise of such
               Options or the conversion or exchange of such
               Convertible Securities; and

                    (c)  Additional Shares of Common Stock
               deemed to have been issued pursuant to Section
               1.7.4, relating to stock dividends, stock
               splits, etc., shall be deemed to have been
               issued for no consideration.

                    1.7.6.  Adjustments for Combinations, etc.  In
          case the outstanding shares of Common Stock shall be
          combined or consolidated, by reclassification or
          otherwise, into a lesser number of shares of Common
          Stock, the Conversion Price in effect immediately prior
          to such combination or consolidation shall, concurrently
          with the effectiveness of such combination or
          consolidation, be proportionately increased.

                    1.7.7.  Dilution in Case of Other Securities. 
          In case any Other Securities shall be issued or sold or
          shall become subject to issue or sale upon the conversion
          or exchange of any stock (or Other Securities) of the
          Company (or any issuer of Other Securities or any other
          Person referred to in Section 1.8) or to subscription,
          purchase or other acquisition pursuant to any Options
          issued or granted by the Company (or any such other
          issuer or Person) for a consideration such as to dilute,
          on a basis consistent with the standards established in
          the other provisions of this Section 1.7, the conversion
          rights granted to holders of Series C Preferred Stock,
          then, and in each such case, the computations,
          adjustments and readjustments provided for in this
          Section 1.7 with respect to the Conversion Price shall be
          made as nearly as possible in the manner so provided and
          applied to determine the amount of Other Securities from
          time to time receivable upon the conversion of the shares
          of Series H Preferred Stock, so as to protect the holders
          of the Series H Preferred Stock against the effect of
          such dilution.

                    1.7.8.  Minimum Adjustment of Conversion Price. 
          If the amount of any adjustment of the Conversion Price
          required pursuant to this Section 1.7 would be less than
          one-half of one percent (1%) of the Conversion Price in
          effect at the time such adjustment is otherwise so
          required to be made, such amount shall be carried forward
          and adjustment with respect thereto made at the time of
          and together with any subsequent adjustment which,
          together with such amount and any other amount or amounts
          so carried forward, shall aggregate at least one-half of
          one percent (1%) of such Conversion Price.

                    1.8.  Consolidation, Merger, etc.

                    1.8.1.  Adjustments for Consolidation, Merger,
          Sale of Assets, Reorganization, etc.  In case the Company
          after the date hereof (a) shall consolidate with or merge
          into any other Person and shall not be the continuing or
          surviving corporation of such consolidation or merger, or
          (b) shall permit any other Person to consolidate with or
          merge into the Company and the Company shall be the
          continuing or surviving Person but, in connection with


          such consolidation or merger, the Common Stock or Other
          Securities shall be changed into or exchanged for stock
          or other securities of any Other Person or cash or any
          other property, or (c) shall transfer all or
          substantially all of its properties or assets to any
          other Person, or (d) shall effect a capital
          reorganization or reclassification of the Common Stock or
          Other Securities (other than a capital reorganization or
          reclassification resulting in the issue of Additional
          Shares of Common Stock for which adjustment in the
          Conversion Price is provided in subsection 1.7.1 or
          1.7.2), then, and in the case of each such transaction
          (excluding any such transaction which constitutes a
          Triggering Event and in connection with which the Company
          requires conversion of the Series H Preferred Stock),
          proper provision shall be made so that, upon the basis
          and the terms and in the manner provided herein, the
          holders of shares of Series H Preferred Stock, upon the
          conversion thereof at any time after the consummation of
          such transaction, shall be entitled to receive (at the
          aggregate Conversion Price in effect at the time of such
          consummation for all Common Stock or Other Securities
          issuable upon such exercise immediately prior to such
          consummation), in lieu of the Common Stock or Other
          Securities issuable upon such exercise prior to such
          consummation, the highest amount of securities, cash or
          other property to which such holder would actually have
          been entitled as a stockholder upon such consummation if
          such holder had exercised the conversion rights
          pertaining to the Series H Preferred Stock immediately
          prior thereto.

                    1.8.2.  Assumption of Obligations. 
          Notwithstanding anything to the contrary herein provided,
          the Company will not effect any of the transactions
          described in subsections (a) through (d) of Section 1.8.1
          (excluding any such transaction which constitutes a
          Triggering Event and in connection with which the Company
          requires conversion of the Series H Preferred Stock)
          unless, prior to the consummation thereof, each Person
          (other than the Company) which may be required to deliver
          any stock, securities, cash or property upon the
          conversion of shares of Series H Preferred Stock as
          provided herein shall assume, by written instrument
          delivered to, and reasonably satisfactory to, the holders
          of the Series H Preferred Stock (a) the obligations of
          the Company with respect to the Series H Preferred Stock
          (and if the Company shall survive the consummation of
          such transaction, such assumption shall be in addition
          to, and shall not release the Company from, any
          continuing obligations of the Company with respect to the
          Series H Preferred Stock), and (b) the obligation to
          deliver to such holder such shares of stock, securities,
          cash or property as, in accordance with the foregoing
          provisions of this Section 1.8, such holder may be
          entitled to receive, and such Person shall have similarly
          delivered to such holders of Series H Preferred Stock an
          opinion of counsel for such Person, which counsel shall
          be reasonably satisfactory to such holders, stating that
          the rights and privileges of the Series H Preferred Stock
          shall thereafter continue in full force and effect and
          the terms thereof (including, without limitation, all of
          the provisions of this Section 1.8) shall be applicable
          to the stock, securities, cash or property which such
          Person may be required to deliver upon any conversion of
          shares of Series H Preferred Stock or the exercise of any
          rights pursuant hereto.

                    1.9.  Other Dilutive Events.  In case any event
          shall occur as to which the provisions of Section 1.7 or
          Section 1.8 are not strictly applicable but the failure
          to make any adjustment would not fairly protect the
          conversion rights pertaining to shares of Series H
          Preferred Stock in accordance with the essential intent
          and principles of such sections, then, in each such case,
          the Company shall appoint a firm of independent certified
          public accountants of recognized national standing (such
          firm to be subject to the approval of the holders of a
          majority of the Series E Preferred Stock and the Series H
          Preferred Stock"), which shall give their opinion
          regarding the adjustment, if any, on a basis consistent
          with the essential intent and principles established in
          Sections 1.7 and 1.8, necessary to preserve, without
          dilution, the conversion rights of the Series E Preferred
          Stock and the Series H Preferred Stock.  Upon receipt of
          such opinion, the Company will promptly mail a copy
          thereof to each holder of Series E Preferred Stock and
          Series H Preferred Stock and shall make the adjustments
          described therein.

                    1.10.  No Dilution or Impairment.  The Company
          will not, by amendment of its certificate of
          incorporation or by-laws or through any consolidation,
          merger, reorganization, transfer of assets, dissolution,
          issue or sale of securities or any other voluntary
          action, avoid or seek to avoid the observance or
          performance of any of the terms of the Series H Preferred
          Stock, but will at all times in good faith assist in the
          carrying out of all such terms and in the taking of all
          such action as may be necessary or appropriate in order
          to protect the rights of the holders of shares of Series
          H Preferred Stock against dilution or other impairment. 
          Without limiting the generality of the foregoing, the
          Company (a) will not permit the par value of any shares
          of stock receivable upon the conversion of Series H
          Preferred Stock to exceed the amount payable therefor
          upon such exercise, (b) will take all such action as may
          be necessary or appropriate in order that the Company may
          validly and legally issue fully paid and non-assessable
          shares of stock on the conversion of the shares of Series
          H Preferred Stock from time to time outstanding, and (c)
          will not take any action which results in any adjustment
          of the Conversion Price if the total number of shares of
          Common Stock (or Other Securities) issuable after the
          action upon the conversion of all of the outstanding
          shares of Series H Preferred Stock would exceed the total
          number of shares of Common Stock (or Other Securities)
          then authorized by the Company's certificate of
          incorporation and available for the purpose of issue upon
          such exercise.

                    1.11.  Accountants' Report as to Adjustments. 
          In each case of any adjustment or readjustment in the
          shares of Common Stock (or Other Securities) issuable
          upon the conversion of shares of Series H Preferred
          Stock, the Company at its expense will promptly compute
          such adjustment or readjustment in accordance with the
          terms hereof and cause independent certified public
          accountants of recognized standing (such firm to be
          subject to the approval of the holders of a majority of
          the outstanding Series E Preferred Stock and Series H
          Preferred Stock) selected by the Company to verify such
          computation and prepare a report setting forth such
          adjustment or readjustment and showing in reasonable
          detail the method of calculation thereof and the facts
          upon which such adjustment or readjustment is based,
          including a statement of (a) the consideration received
          or to be received by the Company for any Additional
          Shares of Common Stock issued or sold or deemed to have
          been issued, (b) the number of shares of Common Stock
          outstanding or deemed to be outstanding, and (c) the
          Conversion Price in effect immediately prior to such
          issue or sale and as adjusted and readjusted (if required
          by Section 1.7) on account thereof.  The Company will
          forthwith mail a copy of each such report to each holder
          of shares of Series E Preferred Stock and Series H
          Preferred Stock and will, upon the written request at any
          time of any holder of shares of Series E Preferred Stock
          and Series H Preferred Stock, furnish to such holder a
          like report setting forth the Conversion Price at the
          time in effect and showing in reasonable detail how it
          was calculated.  The Company will also keep copies of all
          such reports at its principal office and will cause the
          same to be available for inspection at such office during
          normal business hours by any holder of Series E Preferred
          Stock or Series H Preferred Stock or any prospective
          purchaser of Series E Preferred Stock or Series H
          Preferred Stock designated by the holder thereof.

                    1.12.  Notices of Corporate Action.  In the
          event of 

                    (a)  any taking by the Company of a record
               of the holders of any class of securities for
               the purpose of determining the holders thereof
               who are entitled to receive any dividend (other
               than dividends payable with respect to the
               Series E Preferred Stock and the Series H
               Preferred Stock and other than a regular
               periodic dividend payable in cash out of earned
               surplus in an amount not exceeding the amount
               of the immediately preceding cash dividend for
               such period) or other distribution, or any
               right to subscribe for, purchase or otherwise
               acquire any shares of stock of any class or any
               other securities or property, or to receive any
               other right, or

                    (b)  any capital reorganization of the
               Company, any reclassification or
               recapitalization of the capital stock of the
               Company or any consolidation or merger
               involving the Company and any other Person or
               any transfer of all or substantially all of the
               assets of the Company to any other Person, or

                    (c)  any voluntary or involuntary
               dissolution, liquidation or winding-up of the
               Company,

          the Company will mail to each holder of shares of Series
          E  Preferred Stock and the Series H Preferred Stock a
          notice specifying (i) the date or expected date on which
          any such record is to be taken for the purpose of such
          dividend, distribution or right, and the amount and
          character of such dividend, distribution or right, and
          (ii) the date or expected date on which any such
          reorganization, reclassification, recapitalization,
          consolidation, merger, transfer, dissolution, liquidation
          or winding-up is to take place and the time, if any such
          time is to be fixed, as of which the holders of record of
          Common Stock (or Other Securities) shall be entitled to
          exchange their shares of Common Stock (or Other
          Securities) for the securities or other property
          deliverable upon such reorganization, reclassification,
          recapitalization, consolidation, merger, transfer,
          dissolution, liquidation or winding-up.  Except for
          notices relating to mandatory conversion or optional
          redemption in connection with a Triggering Event, such
          notices shall be mailed at least forty-five (45) days
          prior to the date of the action therein specified.

                    1.13.  Retirement of Converted or Redeemed
          Shares.  No share or shares of Series H Preferred Stock
          acquired by the Company by reason of optional or
          mandatory redemption, purchase, conversion or otherwise
          shall be re-issued and all such shares shall be
          cancelled, retired and eliminated from the shares which
          the Company shall be authorized to issue.  The Company
          may from time to time take such appropriate corporate
          action as may be necessary to reduce the authorized
          number of shares of Series H Preferred Stock accordingly.

          FURTHER RESOLVED, that, before the Company shall issue
          any shares of Series H Preferred Stock, a certificate
          pursuant to Section 151 of the DGCL shall be made,
          executed, acknowledged, filed, and recorded in accordance
          with the provisions of Section 103 and 151 of the DGCL,
          and the proper officers of the Company be, and they
          hereby are, authorized and directed to do all acts and
          things which may be necessary or proper in their opinion
          to carry into effect the purposes and intent of this and
          the foregoing resolutions.

          IN WITNESS WHEREOF, the Company has caused this Certificate to
          be signed in its name and on its behalf and attested on this
          30th day of January, 1996 by duly authorized officers of this
          Corporation.

               Nestor, Inc. (the "Company"), a Delaware
     corporation, for value received, hereby certifies that
     Wand/Nestor Investments L.P. ("Wand"), or registered
     assigns, is entitled to purchase from the Company 511,885
     duly authorized, validly issued, fully paid and
     nonassessable shares of Common Stock par value $.01 per
     share (the "Common Stock"), of the Company at the
     purchase price per share of $.65, at any time or from
     time to time prior to 5:00 P.M., New York City time, on
     August 1, 2004 (or such later date as may be determined
     pursuant to section 19), all subject to the terms,
     conditions and adjustments set forth below in this
     Warrant.

               This Warrant is issued in exchange for a
     warrant issued pursuant to the First Amended and Restated
     Standby Financing and Purchase Agreement, dated as of
     June 30, 1995 (the "Revised Standby Agreement"), by and
     between the Company and Wand in exchange for the Common
     Stock Purchase Warrants originally issued in connection
     with the issue and private sale by the Company of Series
     C Preferred Stock, pursuant to the Securities Purchase
     Agreement (the "Purchase Agreement"), dated as of August
     1, 1994, between the Company and Wand.  This Warrant is
     being issued in connection with the exchange of the
     outstanding Series C Preferred Stock for Series E
     Convertible Preferred Stock (the "Series E Preferred
     Stock") and Series H Convertible Preferred Stock (the
     "Series H Preferred Stock") of the Company pursuant to
     the Securities Purchase and Exchange Agreement, dated as
     of January 31, 1996, among the Company, Wand and certain
     affiliates of Wand.  Certain capitalized terms used in
     this Warrant are defined in section 14; references to an
     "Exhibit" are, unless otherwise specified, to one of the
     Exhibits attached to this Warrant and references to a
     "section" are, unless otherwise specified, to one of the
     sections of this Warrant.

               1.  Exercise of Warrant.  1.1.  Manner of
     Exercise.  This Warrant may be exercised by the holder
     hereof, in whole or in part, during normal business hours
     on any Business Day, by surrender of this Warrant to the
     Company at its principal office, accompanied by a
     subscription   substantially in the form attached to this
     Warrant (or a reasonable facsimile thereof) duly executed
     by such holder and accompanied by payment, in cash, by
     certified or official bank check payable to the order of
     the Company, or in the manner provided in Section 1.5, in
     the amount obtained by multiplying (a) the number of
     shares of Common Stock (without giving effect to any
     adjustment thereof) designated in such subscription by
     (b) $.65, and such holder shall thereupon be entitled to
     receive the number of duly authorized, validly issued,
     fully paid and nonassessable shares of Common Stock (or
     Other Securities) determined as provided in sections 2
     through 4.

               1.2.  When Exercise Effective.  Each exercise
     of this Warrant shall be deemed to have been effected
     immediately prior to the close of business on the
     Business Day on which this Warrant shall have been
     surrendered to the Company as provided in section 1.1,
     and at such time the Person or Persons in whose name or
     names any certificate or certificates for shares of
     Common Stock (or Other Securities) shall be issuable upon
     such exercise as provided in section 1.3 shall be deemed
     to have become the holder or holders of record thereof.

               1.3.  Delivery of Stock Certificates, etc.  As
     soon as practicable after each exercise of this Warrant,
     in whole or in part, and in any event within five
     Business Days thereafter, the Company at its expense
     (including the payment by it of any applicable issue
     taxes) will cause to be issued in the name of and
     delivered to the holder hereof or, subject to section 9,
     as such holder (upon payment by such holder of any
     applicable transfer taxes) may direct,

               (a)  a certificate or certificates for the
          number of duly authorized, validly issued, fully
          paid and nonassessable shares of Common Stock (or
          Other Securities) to which such holder shall be
          entitled upon such exercise plus, in lieu of any
          fractional share to which such holder would
          otherwise be entitled, cash in an amount equal to
          the same fraction of the Market Price per share on
          the Business Day next preceding the date of such
          exercise, and

               (b)  in case such exercise is in part only, a
          new Warrant or Warrants of like tenor, calling in
          the aggregate on the face or faces thereof for the
          number of shares of Common Stock equal (without
          giving effect to any adjustment thereof) to the
          number of such shares called for on the face of this
          Warrant minus the number of such shares designated
          by the holder upon such exercise as provided in
          section 1.1.

               1.4.  Company to Reaffirm Obligations.  The
     Company will, at the time of each exercise of this
     Warrant, upon the request of the holder hereof,
     acknowledge in writing its continuing obligation to
     afford to such holder all rights (including, without
     limitation, any rights to registration, pursuant to the
     Registration Rights Agreement referred to in section 8,
     of the shares of Common Stock or Other Securities issued
     upon such exercise) to which such holder shall continue
     to be entitled after such exercise in accordance with the
     terms of this Warrant, provided that if the holder of
     this Warrant shall fail to make any such request, such
     failure shall not affect the continuing obligation of the
     Company to afford such rights to such holder.

               1.5.  Payment by Application of Shares
     Otherwise Issuable.  Upon any exercise of this Warrant,
     the holder hereof may, at its option, instruct the
     Company, by written notice accompanying the surrender of
     this Warrant at the time of such exercise, to apply to
     the payment required by section 1.1 such number of the
     shares of Common Stock otherwise issuable to such holder
     upon such exercise as shall be specified in such notice,
     in which case an amount equal to the excess of the
     aggregate Current Market Price of such specified number
     of shares on the date of exercise over the portion of the
     payment required by section 1.1 attributable to such
     shares shall be deemed to have been paid to the Company
     and the number of shares issuable upon such exercise
     shall be reduced by such specified number.

               2.  Adjustment of Common Stock Issuable Upon
     Exercise.  2.1.  General; Warrant Price.  The number of
     shares of Common Stock which the holder of this Warrant
     shall be entitled to receive upon each exercise hereof
     shall be determined by multiplying the number of shares
     of Common Stock which would otherwise (but for the
     provisions of this section 2) be issuable upon such
     exercise, as designated by the holder hereof pursuant to
     section 1.1, by the fraction of which (a) the numerator
     is $.65 and (b) the denominator is the Warrant Price in
     effect on the date of such exercise.  The "Warrant Price"
     shall initially be $.65 per share, shall be adjusted and
     readjusted from time to time as provided in this section
     2 and, as so adjusted or readjusted, shall remain in
     effect until a further adjustment or readjustment thereof
     is required by this section 2.  In addition to the other
     adjustments herein provided, the "Warrant Price" shall be
     subject to the following special adjustments:

               (i)  If the Series E Preferred Stock and Series
                    H Preferred Stock are redeemed by the
                    Company on or prior to August 1, 2000 then
                    the "Warrant Price" shall

                    (A)  be reduced by 25%, after all other
                         adjustments required by this section
                         2 have been made, if the redemption
                         occurs prior to August 1, 1996;

                    (B)  be reduced by 20%, after all other
                         adjustments required by this section
                         2 have been made, if the redemption
                         occurs on or after August 1, 1996 and
                         prior to August 1, 1997;

                    (C)  be reduced by 15%, after all other
                         adjustments required by this section
                         2 have been made, if the redemption
                         occurs on or after August 1, 1997 and
                         prior to August 1, 1998;

                    (D)  be reduced by 10%, after all other
                         adjustments required by this section
                         2 have been made, if the redemption


                         occurs on or after August 1, 1998 and
                         prior to August 1, 1999; and

                    (E)  be reduced by 5%, after all other
                         adjustments required by this section
                         2 have been made, if the redemption
                         occurs on or after August 1, 1999 and
                         prior to August 1, 2000.

               2.2.  Adjustment of Warrant Price.

               2.2.1  Issuance of Additional Shares of Common
     Stock.  In case the Company at any time or from time to
     time after the date hereof shall issue or sell Additional
     Shares of Common Stock (including Additional Shares of
     Common Stock deemed to be issued pursuant to section 2.3
     or 2.4) without consideration or for a consideration per
     share less than the Warrant Price in effect immediately
     prior to such issue or sale, then, and in each such case,
     subject to section 2.8, such Warrant Price shall be
     reduced, concurrently with such issue or sale, to a price
     (calculated to the nearest .001 of a cent) determined by
     multiplying such Warrant Price by a fraction

               (a)  the numerator of which shall be (i) the
          number of shares of Common Stock outstanding
          immediately prior to such issue or sale plus (ii)
          the number of shares of Common Stock which the
          aggregate consideration received by the Company for
          the total number of such Additional Shares of Common
          Stock so issued or sold would purchase at such
          Warrant Price, and

               (b)  the denominator of which shall be the
          number of shares of Common Stock outstanding
          immediately after such issue or sale,

     provided that, for the purposes of this section 2.2.1,
     (x) immediately after any Additional Shares of Common
     Stock are deemed to have been issued pursuant to section
     2.3 or 2.4, such Additional Shares shall be deemed to be
     outstanding, and (y) treasury shares shall not be deemed
     to be outstanding.

               2.2.2  Extraordinary Dividends and
     Distributions.  In case the Company at any time or from
     time to time after the date hereof shall declare, order,
     pay or make a dividend or other distribution (including,
     without limitation, any distribution of other or
     additional stock or other securities or property or
     Options by way of dividend or spin-off, reclassification,
     recapitalization or similar corporate rearrangement) on
     the Common Stock, other than (a) a dividend payable in
     Additional Shares of Common Stock or (b) cash dividends
     during any fiscal year of the Company that do not exceed
     twenty percent (20%) of the after tax earnings per share
     of the Common Stock for the immediately preceding fiscal
     year of the Company, then, and in each such case, subject
     to section 2.8, the Warrant Price in effect immediately
     prior to the close of business on the record date fixed
     for the determination of holders of any class of
     securities entitled to receive such dividend or
     distribution shall be reduced, effective as of the close
     of business on such record date, to a price (calculated
     to the nearest .001 of a cent) determined by multiplying
     such Warrant Price by a fraction

               (x)  the numerator of which shall be the
          Current Market Price in effect on such record date
          or, if the Common Stock trades on an ex-dividend
          basis, on the date prior to the commencement of ex-
          dividend trading, less the amount of such dividend
          or distribution (as determined in good faith by the
          Board of Directors of the Company, subject to 
          confirmation by a firm of independent certified
          public accountants of recognized national standing
          approved by Wand/Nestor Investments L.P.) applicable
          to one share of Common Stock, and

               (y)  the denominator of which shall be such
          Current Market Price.

               2.3.  Treatment of Options and Convertible
     Securities.  In case the Company at any time or from time
     to time after the date hereof shall issue, sell, grant or
     assume, or shall fix a record date for the determination
     of holders of any class of securities entitled to
     receive, any Options or Convertible Securities, then, and
     in each such case, the maximum number of Additional
     Shares of Common Stock (as set forth in the instrument
     relating thereto, without regard to any provisions
     contained therein for a subsequent adjustment of such
     number) issuable upon the exercise of such Options or, in
     the case of Convertible Securities and Options therefor,
     the conversion or exchange of such Convertible
     Securities, shall be deemed to be Additional Shares of
     Common Stock issued as of the time of such issue, sale,
     grant or assumption or, in case such a record date shall
     have been fixed, as of the close of business on such
     record date (or, if the Common Stock trades on an ex-
     dividend basis, on the date prior to the commencement of
     ex-dividend trading), provided that such Additional
     Shares of Common Stock shall not be deemed to have been
     issued unless the consideration per share (determined
     pursuant to section 2.5) of such shares would be less
     than the Warrant Price in effect on the date of and
     immediately prior to such issue, sale, grant or
     assumption or immediately prior to the close of business
     on such record date (or, if the Common Stock trades on an
     ex-dividend basis, on the date prior to the commencement
     of ex-dividend trading), as the case may be, and
     provided, further, that in any such case in which
     Additional Shares of Common Stock are deemed to be issued

               (a)  no further adjustment of the Warrant Price
          shall be made upon the subsequent issue or sale of
          Convertible Securities or shares of Common Stock
          upon the exercise of such Options or the conversion
          or exchange of such Convertible Securities;

               (b)  if such Options or Convertible Securities
          by their terms provide, with the passage of time or
          otherwise, for any increase in the consideration
          payable to the Company, or decrease in the number of
          Additional Shares of Common Stock issuable, upon the
          exercise, conversion or exchange thereof (by change
          of rate or otherwise), the Warrant Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon any such increase or decrease becoming
          effective, be recomputed to reflect such increase or
          decrease insofar as it affects such Options, or the
          rights of conversion or exchange under such
          Convertible Securities, which are outstanding at
          such time;

               (c)  upon the expiration (or purchase by the
          Company and cancellation or retirement) of any such
          Options which shall not have been exercised or the
          expiration of any rights of conversion or exchange
          under any such Convertible Securities which (or
          purchase by the Company and cancellation or
          retirement of any such Convertible Securities the
          rights of conversion or exchange under which) shall
          not have been exercised, the Warrant Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon such expiration (or such cancellation or
          retirement, as the case may be), be recomputed as
          if:

                    (i)  in the case of Options for Common
               Stock or Convertible Securities, the only
               Additional Shares of Common Stock issued or
               sold were the Additional Shares of Common
               Stock, if any, actually issued or sold upon the
               exercise of such Options or the conversion or
               exchange of such Convertible Securities and the
               consideration received therefor was the
               consideration actually received by the Company
               for the issue, sale, grant or assumption of all
               such Options, whether or not exercised, plus
               the consideration actually received by the
               Company upon such exercise, or for the issue or
               sale of all such Convertible Securities which
               were actually converted or exchanged, plus the
               additional consideration, if any, actually
               received by the Company upon such conversion or
               exchange, and

                    (ii) in the case of Options for
               Convertible Securities, only the Convertible
               Securities, if any, actually issued or sold
               upon the exercise of such Options were issued
               at the time of the issue, sale, grant or
               assumption of such Options, and the
               consideration received by the Company for the
               Additional Shares of Common Stock deemed to
               have then been issued was the consideration
               actually received by the Company for the issue,
               sale, grant or assumption of all such Options,
               whether or not exercised, plus the
               consideration deemed to have been received by
               the Company (pursuant to section 2.5) upon the
               issue or sale of such Convertible Securities
               with respect to which such Options were
               actually exercised;

               (d)  no readjustment pursuant to subdivision
          (b) or (c) above shall have the effect of increasing
          the Warrant Price by an amount in excess of the
          amount of the adjustment thereof originally made in
          respect of the issue, sale, grant or assumption of
          such Options or Convertible Securities; and 

               (e)  in the case of any such Options which
          expire by their terms not more than 30 days after
          the date of issue, sale, grant or assumption
          thereof, no adjustment of the Warrant Price shall be
          made until the expiration or exercise of all such
          Options, whereupon such adjustment shall be made in
          the manner provided in subdivision (c) above.

               2.4.  Treatment of Stock Dividends, Stock
     Splits, etc.  In case the Company at any time or from
     time to time after the date hereof shall declare or pay
     any dividend on the Common Stock payable in Common Stock,
     or shall effect a subdivision of the outstanding shares
     of Common Stock into a greater number of shares of Common
     Stock (by reclassification or otherwise than by payment
     of a dividend in Common Stock), then, and in each such
     case, Additional Shares of Common Stock shall be deemed
     to have been issued (a) in the case of any such dividend,
     immediately after the close of business on the record
     date for the determination of holders of any class of
     securities entitled to receive such dividend, or (b) in
     the case of any such subdivision, at the close of
     business on the day immediately prior to the day upon
     which such corporate action becomes effective.

               2.5.  Computation of Consideration.  For the
     purposes of this section 2,

               (a)  the consideration for the issue or sale of
          any Additional Shares of Common Stock shall,
          irrespective of the accounting treatment of such
          consideration,

                    (i)  insofar as it consists of cash, be
               computed at the net amount of cash received by
               the Company, without deducting any expenses
               paid or incurred by the Company or any
               commissions or compensation paid or concessions
               or discounts allowed to underwriters, dealers
               or others performing similar services in
               connection with such issue or sale,

                    (ii)  insofar as it consists of property
               (including securities) other than cash, be
               computed at the fair value thereof at the time
               of such issue or sale, as determined in good
               faith by the Board of Directors of the Company
               (subject to  confirmation by a firm of
               independent certified public accountants of
               recognized  standing approved by Wand/Nestor
               Investments L.P.), and 

                    (iii)  in case Additional Shares of Common
               Stock are issued or sold together with other
               stock or securities or other assets of the
               Company for a consideration which covers both,
               be the portion of such consideration so
               received, computed as provided in clauses (i)
               and (ii) above, allocable to such Additional
               Shares of Common Stock, all as determined in
               good faith by the Board of Directors of the
               Company (subject to  confirmation by a firm of
               independent certified public accountants of
               recognized  standing approved by Wand/Nestor
               Investments L.P.);

               (b)  Additional Shares of Common Stock deemed
          to have been issued pursuant to section 2.3,
          relating to Options and Convertible Securities,
          shall be deemed to have been issued for a
          consideration per share determined by dividing

                    (i)  the total amount, if any, received
               and receivable by the Company as consideration
               for the issue, sale, grant or assumption of the
               Options or Convertible Securities in question,
               plus the minimum aggregate amount of additional
               consideration (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such consideration to protect
               against dilution) payable to the Company upon
               the exercise in full of such Options or the
               conversion or exchange of such Convertible
               Securities or, in the case of Options for
               Convertible Securities, the exercise of such
               Options for Convertible Securities and the
               conversion or exchange of such Convertible
               Securities, in each case computing such
               consideration as provided in the foregoing
               subdivision (a),

     by

                    (ii)  the maximum number of shares of
               Common Stock (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such number to protect against
               dilution) issuable upon the exercise of such
               Options or the conversion or exchange of such
               Convertible Securities; and

               (c)  Additional Shares of Common Stock deemed
          to have been issued pursuant to section 2.4,
          relating to stock dividends, stock splits, etc.,
          shall be deemed to have been issued for no
          consideration.

               2.6.  Adjustments for Combinations, etc.  In
     case the outstanding shares of Common Stock shall be
     combined or consolidated, by reclassification or
     otherwise, into a lesser number of shares of Common
     Stock, the Warrant Price in effect immediately prior to
     such combination or consolidation shall, concurrently
     with the effectiveness of such combination or
     consolidation, be proportionately increased.

               2.7.  Dilution in Case of Other Securities.  In
     case any Other Securities shall be issued or sold or
     shall become subject to issue or sale upon the conversion
     or exchange of any stock (or Other Securities) of the
     Company (or any issuer of Other Securities or any other
     Person referred to in section 3) or to subscription,
     purchase or other acquisition pursuant to any Options
     issued or granted by the Company (or any such other
     issuer or Person) for a consideration such as to dilute,
     on a basis consistent with the standards established in
     the other provisions of this section 2, the purchase
     rights granted by this Warrant, then, and in each such
     case, the computations, adjustments and readjustments
     provided for in this section 2 with respect to the
     Warrant Price shall be made as nearly as possible in the
     manner so provided and applied to determine the amount of
     Other Securities from time to time receivable upon the
     exercise of the Warrants, so as to protect the holders of
     the Warrants against the effect of such dilution.

               2.8.  Minimum Adjustment of Warrant Price.  If
     the amount of any adjustment of the Warrant Price
     required pursuant to this section 2 would be less than
     one percent (1%) of the Warrant Price in effect at the
     time such adjustment is otherwise so required to be made,
     such amount shall be carried forward and adjustment with
     respect thereto made at the time of and together with any
     subsequent adjustment which, together with such amount
     and any other amount or amounts so carried forward, shall
     aggregate at least one percent (1%) of such Warrant
     Price.

               3.  Consolidation, Merger, etc.  3.1.  
     Adjustments for Consolidation, Merger, Sale of Assets,
     Reorganization, etc.  In case the Company after the date
     hereof (a) shall consolidate with or merge into any other
     Person and shall not be the continuing or surviving
     corporation of such consolidation or merger, or (b) shall
     permit any other Person to consolidate with or merge into
     the Company and the Company shall be the continuing or
     surviving Person but, in connection with such
     consolidation or merger, the Common Stock or Other
     Securities shall be changed into or exchanged for stock
     or other securities of any other Person or cash or any
     other property, or (c) shall transfer all or
     substantially all of its properties or assets to any
     other Person, or (d) shall effect a capital
     reorganization or reclassification of the Common Stock or
     Other Securities (other than a capital reorganization or
     reclassification resulting in the issue of Additional
     Shares of Common Stock for which adjustment in the
     Warrant Price is provided in section 2.2.1 or 2.2.2),
     then, and in the case of each such transaction, proper
     provision shall be made so that, upon the basis and the
     terms and in the manner provided in this Warrant, the
     holder of this Warrant, upon the exercise hereof at any
     time after the consummation of such transaction, shall be
     entitled to receive (at the aggregate Warrant Price in
     effect at the time of such consummation for all Common
     Stock or Other Securities issuable upon such exercise
     immediately prior to such consummation), in lieu of the
     Common Stock or Other Securities issuable upon such
     exercise prior to such consummation, the highest amount
     of securities, cash or other property to which such
     holder would actually have been entitled as a shareholder
     upon such consummation if such holder had exercised the
     rights represented by this Warrant immediately prior
     thereto, subject to adjustments (subsequent to such
     consummation) as nearly equivalent as possible to the
     adjustments provided for in sections 2 through 4.

               3.2.  Assumption of Obligations. 
     Notwithstanding anything contained in the Warrants or in
     the Purchase Agreement to the contrary, the Company will
     not effect any of the transactions described in clauses
     (a) through (d) of section 3.1 unless, prior to the
     consummation thereof, each Person (other than the
     Company) which may be required to deliver any stock,
     securities, cash or property upon the exercise of this
     Warrant as provided herein shall assume, by written
     instrument delivered to, and reasonably satisfactory to,
     the holder of this Warrant, (a) the obligations of the
     Company under this Warrant (and if the Company shall
     survive the consummation of such transaction, such
     assumption shall be in addition to, and shall not release
     the Company from, any continuing obligations of the
     Company under this Warrant), (b) the obligations of the
     Company under the Registration Rights Agreement and (c)
     the obligation to deliver to such holder such shares of
     stock, securities, cash or property as, in accordance
     with the foregoing provisions of this section 3, such
     holder may be entitled to receive, and such Person shall
     have similarly delivered to such holder an opinion of
     counsel for such Person, which counsel shall be
     reasonably satisfactory to such holder, stating that this
     Warrant shall thereafter continue in full force and
     effect and the terms hereof (including, without
     limitation, all of the provisions of this section 3)
     shall be applicable to the stock, securities, cash or
     property which such Person may be required to deliver
     upon any exercise of this Warrant or the exercise of any
     rights pursuant hereto.  Nothing in this section 3 shall
     be deemed to authorize the Company to enter into any
     transaction not otherwise permitted by the Purchase
     Agreement.

               4.  Other Dilutive Events.  In case any event
     shall occur as to which the provisions of section 2 or
     section 3 are not strictly applicable but the failure to
     make any adjustment would not fairly protect the purchase
     rights represented by this Warrant in accordance with the
     essential intent and principles of such sections, then,
     in each such case, the Company shall appoint a firm of
     independent certified public accountants of recognized
     national standing (such firm to be subject to the
     approval of Wand/Nestor Investments L.P.), which shall
     give their opinion regarding the adjustment, if any, on a
     basis consistent with the essential intent and principles
     established in sections 2 and 3, necessary to preserve,
     without dilution, the purchase rights represented by this
     Warrant.  Upon receipt of such opinion, the Company will
     promptly mail a copy thereof to the holder of this
     Warrant and shall make the adjustments described therein.

               5.  No Dilution or Impairment.  The Company
     will not, by amendment of its certificate of
     incorporation or through any consolidation, merger,
     reorganization, transfer of assets, dissolution, issue or
     sale of securities or any other voluntary action, avoid
     or seek to avoid the observance or performance of any of
     the terms of this Warrant, but will at all times in good
     faith assist in the carrying out of all such terms and in
     the taking of all such action as may be necessary or
     appropriate in order to protect the rights of the holder
     of this Warrant against dilution or other impairment. 
     Without limiting the generality of the foregoing, the
     Company (a) will not permit the par value of any shares
     of stock receivable upon the exercise of this Warrant to
     exceed the amount payable therefor upon such exercise,
     (b) will take all such action as may be necessary or
     appropriate in order that the Company may validly and
     legally issue fully paid and nonassessable shares of
     stock on the exercise of the Warrants from time to time
     outstanding, and (c) will not take any action which
     results in any adjustment of the Warrant Price if the
     total number of shares of Common Stock (or Other
     Securities) issuable after the action upon the exercise
     of all of the Warrants would exceed the total number of
     shares of Common Stock (or Other Securities) then
     authorized by the Company's certificate of incorporation
     and available for the purpose of issue upon such
     exercise.

               6.  Accountants' Report as to Adjustments.  In
     each case of any adjustment or readjustment in the shares
     of Common Stock (or Other Securities) issuable upon the
     exercise of this Warrant, the Company at its expense will
     promptly compute such adjustment or readjustment in
     accordance with the terms of this Warrant and cause
     independent certified public accountants of recognized
     standing (such firm to be subject to the approval of
     Wand/Nestor Investments L.P.) selected by the Company to
     verify such computation and prepare a report setting
     forth such adjustment or readjustment and showing in
     reasonable detail the method of calculation thereof and
     the facts upon which such adjustment or readjustment is
     based, including a statement of (a) the consideration
     received or to be received by the Company for any
     Additional Shares of Common Stock issued or sold or
     deemed to have been issued, (b) the number of shares of
     Common Stock outstanding or deemed to be outstanding, and
     (c) the Warrant Price in effect immediately prior to such
     issue or sale and as adjusted and readjusted (if required
     by section 2) on account thereof.  The Company will
     forthwith mail a copy of each such report to each holder
     of a Warrant and will, upon the written request at any
     time of any holder of a Warrant, furnish to such holder a
     like report setting forth the Warrant Price at the time
     in effect and showing in reasonable detail how it was
     calculated.  The Company will also keep copies of all
     such reports at its principal office and will cause the
     same to be available for inspection at such office during
     normal business hours by any holder of a Warrant or any
     prospective purchaser of a Warrant designated by the
     holder thereof.

               7.  Notices of Corporate Action.  In the event of
               (a)  any taking by the Company of a record of
          the holders of any class of securities for the
          purpose of determining the holders thereof who are
          entitled to receive any dividend (other than a
          regular periodic dividend payable in cash out of
          earned surplus in an amount not exceeding the amount
          of the immediately preceding cash dividend for such
          period) or other distribution, or any right to
          subscribe for, purchase or otherwise acquire any
          shares of stock of any class or any other securities
          or property, or to receive any other right, or 

               (b)  any capital reorganization of the Company,
          any reclassification or recapitalization of the
          capital stock of the Company or any consolidation or
          merger involving the Company and any other Person or
          any transfer of all or substantially all the assets
          of the Company to any other Person, or

               (c)  any voluntary or involuntary dissolution,
          liquidation or winding-up of the Company,

     the Company will mail to each holder of a Warrant a
     notice specifying (i) the date or expected date on which
     any such record is to be taken for the purpose of such
     dividend, distribution or right, and the amount and
     character of such dividend, distribution or right, and
     (ii) the date or expected date on which any such
     reorganization, reclassification, recapitalization,
     consolidation, merger, transfer, dissolution, liquidation
     or winding-up is to take place and the time, if any such
     time is to be fixed, as of which the holders of record of
     Common Stock (or Other Securities) shall be entitled to
     exchange their shares of Common Stock (or Other
     Securities) for the securities or other property
     deliverable upon such reorganization, reclassification,
     recapitalization, consolidation, merger, transfer,
     dissolution, liquidation or winding-up.  Such notice
     shall be mailed at least 45 days prior to the date
     therein specified.

               8.  Registration of Common Stock.  If any
     shares of Common Stock required to be reserved for
     purposes of exercise of this Warrant require registration
     with or approval of any governmental authority under any
     federal or state law (other than the Securities Act)
     before such shares may be issued upon exercise, the
     Company will, at its expense and as expeditiously as
     possible, use its best efforts to cause such shares to be
     duly registered or approved, as the case may be.  The
     shares of Common Stock (and Other Securities) issuable
     upon exercise of this Warrant (or upon conversion of any
     shares of Common Stock issued upon such exercise) shall
     constitute Registrable Securities (as such term is
     defined in the Registration Rights Agreement).  Each
     holder of this Warrant shall be entitled to all of the
     benefits afforded to a holder of any such Registrable
     Securities under the Registration Rights Agreement and
     such holder, by its acceptance of this Warrant, agrees to
     be bound by and to comply with the terms and conditions
     of the Registration Rights Agreement applicable to such
     holder as a holder of such Registrable Securities.  At
     any such time as Common Stock is listed on any national
     securities exchange, the Company will, at its expense,
     obtain promptly and maintain the approval for listing on
     each such exchange, upon official notice of issuance, the
     shares of Common Stock issuable upon exercise of the then
     outstanding Warrants and maintain the listing of such
     shares after their issuance; and the Company will also
     list on such national securities exchange, will register
     under the Exchange Act and will maintain such listing of,
     any Other Securities that at any time are issuable upon
     exercise of the Warrants, if and at the time that any
     securities of the same class shall be listed on such
     national securities exchange by the Company.

               9.  Restrictions on Transfer.  9.1. 
     Restrictive Legends.  Except as otherwise permitted by
     this section 9, each Warrant (including each Warrant
     issued upon the transfer of any Warrant) shall be stamped
     or otherwise imprinted with a legend in substantially the
     following form:

               "THE WARRANT REPRESENTED BY THIS

          WARRANT) HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, OR THE
          SECURITIES LAWS OF ANY STATE IN RELIANCE ON
          CERTAIN EXEMPTIONS FROM REGISTRATION

          OTHER TRANSFER OF SUCH WARRANT (AND OF SUCH
          SHARES OF COMMON STOCK OR OTHER SECURITIES) IS
          SUBJECT TO COMPLIANCE WITH APPLICABLE
          SECURITIES LAWS AND REGULATIONS AND CERTAIN
          RESTRICTIONS AND CONDITIONS CONTAINED IN A
          CERTAIN SECURITIES PURCHASE AGREEMENT AND
          RELATED AGREEMENTS DATED AS OF AUGUST 1, 1994. 
          THE HOLDER OF THIS CERTIFICATE BY ACCEPTANCE
          HEREOF AGREES TO BE BOUND BY SUCH RESTRICTIONS
          AND CONDITIONS.  A COPY OF THE PURCHASE
          AGREEMENT IS ON FILE WITH THE SECRETARY OF THE
          COMPANY."

     Except as otherwise permitted by this section 9, each
     certificate for Common Stock (or Other Securities) issued
     upon the exercise of any Warrant, and each certificate
     issued upon the transfer of any such Common Stock (or
     Other Securities), shall be stamped or otherwise
     imprinted with a legend in substantially the following
     form:

               "THE SHARES OF STOCK REPRESENTED BY THIS
          CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, OR THE
          SECURITIES LAWS OF ANY STATE IN RELIANCE ON
          CERTAIN EXEMPTIONS FROM REGISTRATION
          THEREUNDER.  THE SALE, PLEDGE, HYPOTHECATION OR
          OTHER TRANSFER OF SUCH SHARES IS SUBJECT TO
          COMPLIANCE WITH APPLICABLE SECURITIES LAWS AND
          REGULATIONS AND CERTAIN RESTRICTIONS AND
          CONDITIONS CONTAINED IN A CERTAIN SECURITIES
          PURCHASE AGREEMENT AND RELATED AGREEMENTS DATED
          AS OF AUGUST 1, 1994.  THE HOLDER OF THIS
          CERTIFICATE BY ACCEPTANCE HEREOF AGREES TO BE
          BOUND BY SUCH RESTRICTIONS AND CONDITIONS.  A
          COPY OF THE PURCHASE AGREEMENT IS ON FILE WITH
          THE SECRETARY OF THE COMPANY."

               10.  Availability of Information.  The Company
     shall timely file the reports required to be filed by it
     under the Securities Act and the Exchange Act (including
     but not limited to the reports under sections 13 and
     15(d) of the Exchange Act referred to in subparagraph (c)
     of Rule 144 adopted by the Commission under the
     Securities Act) and the rules and regulations adopted by
     the Commission thereunder (or, if the Company is not
     required to file such reports, will, upon the request of
     any holder of Registrable Securities, make publicly
     available other information) and will take such further
     action as any holder of Registrable Securities may
     reasonably request, all to the extent required from time
     to time to enable such holder to sell Registrable
     Securities without registration under the Securities Act
     within the limitation of the exemptions provided by (a)
     Rule 144 under the Securities Act, as such Rule may be
     amended from time to time, or (b) any similar rule or
     regulation hereafter adopted by the Commission.  Upon the
     request of any holder of Registrable Securities, the
     Company will deliver to such holder a written statement
     as to whether it has complied with the requirements of
     this section 10.

               11.  Reservation of Stock, etc.  The Company
     will at all times reserve and keep available, solely for
     issuance and delivery upon exercise of the Warrants, the
     number of shares of Common Stock (or Other Securities)
     from time to time issuable upon exercise of all Warrants
     at the time outstanding.  All shares of Common Stock (or
     Other Securities) issuable upon exercise of any Warrants
     shall be duly authorized and, when issued upon such
     exercise, shall be validly issued and, in the case of
     shares, fully paid and nonassessable with no liability on
     the part of the holders thereof.

               12.  Registration and Transfer of Warrants,
     etc.

               12.1. Warrant Register; Ownership of Warrants. 
     The Company will keep at its principal office a register
     in which the Company will provide for the registration of
     Warrants and the registration of transfers of Warrants. 
     The Company may treat the Person in whose name any
     Warrant is registered on such register as the owner
     thereof for all other purposes, and the Company shall not
     be affected by any notice to the contrary, except that,
     if and when any Warrant is properly assigned in blank,
     the Company may (but shall not be obligated to) treat the
     bearer thereof as the owner of such Warrant for all
     purposes.  Subject to section 9, a Warrant, if properly
     assigned, may be exercised by a new holder without a new
     Warrant first having been issued.

               12.2.  Transfer and Exchange of Warrants.  Upon
     surrender of any Warrant for registration of transfer or
     for exchange to the Company at its principal office, the
     Company at its expense will (subject to compliance with
     section 9, if applicable) execute and deliver in exchange
     therefor a new Warrant or Warrants of like tenor, in the
     name of such holder or as such holder (upon payment by
     such holder of any applicable transfer taxes) may direct,
     calling in the aggregate on the face or faces thereof for
     the number of shares of Common Stock called for on the
     face or faces of the Warrant or Warrants so surrendered. 

               12.3.  Replacement of Warrants.  Upon receipt
     of evidence reasonably satisfactory to the Company of the
     loss, theft, destruction or mutilation of any Warrant
     and, in the case of any such loss, theft or destruction
     of any Warrant, upon delivery of an indemnity bond in
     such reasonable amount as the Company may determine or,
     in the case of any such mutilation, upon the surrender of
     such Warrant for cancellation to the Company at its
     principal office, the Company at its expense will execute
     and deliver, in lieu thereof, a new Warrant of like
     tenor.  

               13.  Registration Rights.  Wand or any assignee
     of this Warrant shall be entitled to all rights and
     benefits regarding the registration of Common Stock and
     Registrable Securities set forth in the Registration
     Rights Agreement.

               Nestor, Inc. (the "Company"), a Delaware
     corporation, for value received, hereby certifies that
     Wand/Nestor Investments L.P. ("Wand"), or registered
     assigns, is entitled to purchase from the Company 358,319
     duly authorized, validly issued, fully paid and
     nonassessable shares of Common Stock, par value $.01 per
     share (the "Common Stock"), of the Company at the
     purchase price per share of $1.00, at any time or from
     time to time prior to 5:00 P.M., New York City time, on
     October 5, 2005 (or such later date as may be determined
     pursuant to section 19), all subject to the terms,
     conditions and adjustments set forth below in this
     Warrant.

               This Warrant is being issued in connection with
     the Securities Purchase and Exchange Agreement, dated as
     of January 31, 1996, among the Company, Wand and certain
     affiliates of Wand, as a replacement for a portion of a
     warrant originally issued by the Company in consideration
     of Wand's performance of its obligations pursuant to the
     First Amended and Restated Standby Financing and Purchase
     Agreement dated as of June 30, 1995 by and between the
     Company and Wand (the "Revised Standby Agreement"). 
     Certain capitalized terms used in this Warrant are
     defined in section 14; references to an "Exhibit" are,
     unless otherwise specified, to one of the Exhibits
     attached to this Warrant and references to a "section"
     are, unless otherwise specified, to one of the sections
     of this Warrant.

               1.  Exercise of Warrant.  1.1.  Manner of
     Exercise.  This Warrant may be exercised by the holder
     hereof, in whole or in part, during normal business hours
     on any Business Day, by surrender of this Warrant to the
     Company at its principal office, accompanied by a
     subscription  substantially in the form attached to this
     Warrant (or a reasonable facsimile thereof) duly executed
     by such holder and accompanied by payment, in cash, by
     certified or official bank check payable to the order of
     the Company, or in the manner provided in Section 1.5, in
     the amount obtained by multiplying (a) the number of
     shares of Common Stock (without giving effect to any
     adjustment thereof) designated in such subscription by
     (b) $1.00, and such holder shall thereupon be entitled to
     receive the number of duly authorized, validly issued,
     fully paid and nonassessable shares of Common Stock (or
     Other Securities) determined as provided in sections 2
     through 4.

               1.2.  When Exercise Effective.  Each exercise
     of this Warrant shall be deemed to have been effected
     immediately prior to the close of business on the
     Business Day on which this Warrant shall have been
     surrendered to the Company as provided in section 1.1,
     and at such time the Person or Persons in whose name or
     names any certificate or certificates for shares of
     Common Stock (or Other Securities) shall be issuable upon
     such exercise as provided in section 1.3 shall be deemed
     to have become the holder or holders of record thereof.

               1.3.  Delivery of Stock Certificates, etc.  As
     soon as practicable after each exercise of this Warrant,
     in whole or in part, and in any event within five
     Business Days thereafter, the Company at its expense
     (including the payment by it of any applicable issue
     taxes) will cause to be issued in the name of and
     delivered to the holder hereof or, subject to section 9,
     as such holder (upon payment by such holder of any
     applicable transfer taxes) may direct,

               (a)  a certificate or certificates for the
          number of duly authorized, validly issued, fully
          paid and nonassessable shares of Common Stock (or
          Other Securities) to which such holder shall be
          entitled upon such exercise plus, in lieu of any
          fractional share to which such holder would
          otherwise be entitled, cash in an amount equal to
          the same fraction of the Market Price per share on
          the Business Day next preceding the date of such
          exercise, and

               (b)  in case such exercise is in part only, a
          new Warrant or Warrants of like tenor, calling in
          the aggregate on the face or faces thereof for the
          number of shares of Common Stock equal (without
          giving effect to any adjustment thereof) to the
          number of such shares called for on the face of this
          Warrant minus the number of such shares designated
          by the holder upon such exercise as provided in
          section 1.1.

               1.4.  Company to Reaffirm Obligations.  The
     Company will, at the time of each exercise of this
     Warrant, upon the request of the holder hereof,
     acknowledge in writing its continuing obligation to
     afford to such holder all rights (including, without
     limitation, any rights to registration, pursuant to the
     Registration Rights Agreement referred to in section 8,
     of the shares of Common Stock or Other Securities issued
     upon such exercise) to which such holder shall continue
     to be entitled after such exercise in accordance with the
     terms of this Warrant, provided that if the holder of
     this Warrant shall fail to make any such request, such
     failure shall not affect the continuing obligation of the
     Company to afford such rights to such holder.

               1.5.  Payment by Application of Shares
     Otherwise Issuable.  Upon any exercise of this Warrant,
     the holder hereof may, at its option, instruct the
     Company, by written notice accompanying the surrender of
     this Warrant at the time of such exercise, to apply to
     the payment required by section 1.1 such number of the
     shares of Common Stock otherwise issuable to such holder
     upon such exercise as shall be specified in such notice,
     in which case an amount equal to the excess of the
     aggregate Current Market Price of such specified number
     of shares on the date of exercise over the portion of the
     payment required by section 1.1 attributable to such
     shares shall be deemed to have been paid to the Company
     and the number of shares issuable upon such exercise
     shall be reduced by such specified number.

               2.  Adjustment of Common Stock Issuable Upon
     Exercise.  2.1.  General; Warrant Price.  The number of
     shares of Common Stock which the holder of this Warrant
     shall be entitled to receive upon each exercise hereof
     shall be determined by multiplying the number of shares
     of Common Stock which would otherwise (but for the
     provisions of this section 2) be issuable upon such
     exercise, as designated by the holder hereof pursuant to
     section 1.1, by the fraction of which (a) the numerator
     is $1.00 and (b) the denominator is the Warrant Price in
     effect on the date of such exercise.  The "Warrant Price"
     shall initially be $1.00 per share, shall be adjusted and
     readjusted from time to time as provided in this section
     2 and, as so adjusted or readjusted, shall remain in
     effect until a further adjustment or readjustment thereof
     is required by this section 2.

               2.2.  Adjustment of Warrant Price.

               2.2.1  Issuance of Additional Shares of Common
     Stock.  In case the Company at any time or from time to
     time after the date hereof shall issue or sell Additional
     Shares of Common Stock (including Additional Shares of
     Common Stock deemed to be issued pursuant to section 2.3
     or 2.4) without consideration or for a consideration per
     share less than the Warrant Price in effect immediately
     prior to such issue or sale, then, and in each such case,
     subject to section 2.8, such Warrant Price shall be
     reduced, concurrently with such issue or sale, to a price
     (calculated to the nearest .001 of a cent) determined by
     multiplying such Warrant Price by a fraction

               (a)  the numerator of which shall be (i) the
          number of shares of Common Stock outstanding
          immediately prior to such issue or sale plus (ii)
          the number of shares of Common Stock which the
          aggregate consideration received by the Company for
          the total number of such Additional Shares of Common
          Stock so issued or sold would purchase at such
          Warrant Price, and

               (b)  the denominator of which shall be the
          number of shares of Common Stock outstanding
          immediately after such issue or sale,

     provided that, for the purposes of this section 2.2.1,
     (x) immediately after any Additional Shares of Common
     Stock are deemed to have been issued pursuant to section
     2.3 or 2.4, such Additional Shares shall be deemed to be
     outstanding, and (y) treasury shares shall not be deemed
     to be outstanding.

               2.2.2  Extraordinary Dividends and
     Distributions.  In case the Company at any time or from
     time to time after the date hereof shall declare, order,
     pay or make a dividend or other distribution (including,
     without limitation, any distribution of other or
     additional stock or other securities or property or
     Options by way of dividend or spin-off, reclassification,
     recapitalization or similar corporate rearrangement) on
     the Common Stock, other than a dividend payable in (a)
     Additional Shares of Common Stock or (b) cash dividends
     during any fiscal year of the Company that do not exceed
     twenty percent (20%) of the after tax earnings per share
     of the Common Stock for the immediately preceding fiscal
     year of the Company, then, and in each such case, subject
     to section 2.8, the Warrant Price in effect immediately
     prior to the close of business on the record date fixed
     for the determination of holders of any class of
     securities entitled to receive such dividend or
     distribution shall be reduced, effective as of the close
     of business on such record date, to a price (calculated
     to the nearest .001 of a cent) determined by multiplying
     such Warrant Price by a fraction

               (x)  the numerator of which shall be the
          Current Market Price in effect on such record date
          or, if the Common Stock trades on an ex-dividend
          basis, on the date prior to the commencement of ex-
          dividend trading, less the amount of such dividend
          or distribution (as determined in good faith by the
          Board of Directors of the Company, subject to 
          confirmation by a firm of independent certified
          public accountants of recognized national standing
          approved by Wand/Nestor Investments L.P.) applicable
          to one share of Common Stock, and

               (y)  the denominator of which shall be such
          Current Market Price.

               2.3.  Treatment of Options and Convertible
     Securities.  In case the Company at any time or from time
     to time after the date hereof shall issue, sell, grant or
     assume, or shall fix a record date for the determination
     of holders of any class of securities entitled to
     receive, any Options or Convertible Securities, then, and
     in each such case, the maximum number of Additional
     Shares of Common Stock (as set forth in the instrument
     relating thereto, without regard to any provisions
     contained therein for a subsequent adjustment of such
     number) issuable upon the exercise of such Options or, in
     the case of Convertible Securities and Options therefor,
     the conversion or exchange of such Convertible
     Securities, shall be deemed to be Additional Shares of
     Common Stock issued as of the time of such issue, sale,
     grant or assumption or, in case such a record date shall
     have been fixed, as of the close of business on such
     record date (or, if the Common Stock trades on an ex-
     dividend basis, on the date prior to the commencement of
     ex-dividend trading), provided that such Additional
     Shares of Common Stock shall not be deemed to have been
     issued unless the consideration per share (determined
     pursuant to section 2.5) of such shares would be less
     than the Warrant Price in effect on the date of and
     immediately prior to such issue, sale, grant or
     assumption or immediately prior to the close of business
     on such record date (or, if the Common Stock trades on an
     ex-dividend basis, on the date prior to the commencement
     of ex-dividend trading), as the case may be, and
     provided, further, that in any such case in which
     Additional Shares of Common Stock are deemed to be issued

               (a)  no further adjustment of the Warrant Price
          shall be made upon the subsequent issue or sale of
          Convertible Securities or shares of Common Stock
          upon the exercise of such Options or the conversion
          or exchange of such Convertible Securities;

               (b)  if such Options or Convertible Securities
          by their terms provide, with the passage of time or
          otherwise, for any increase in the consideration
          payable to the Company, or decrease in the number of
          Additional Shares of Common Stock issuable, upon the
          exercise, conversion or exchange thereof (by change
          of rate or otherwise), the Warrant Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon any such increase or decrease becoming
          effective, be recomputed to reflect such increase or
          decrease insofar as it affects such Options, or the
          rights of conversion or exchange under such
          Convertible Securities, which are outstanding at
          such time;

               (c)  upon the expiration (or purchase by the
          Company and cancellation or retirement) of any such
          Options which shall not have been exercised or the
          expiration of any rights of conversion or exchange
          under any such Convertible Securities which (or
          purchase by the Company and cancellation or
          retirement of any such Convertible Securities the
          rights of conversion or exchange under which) shall
          not have been exercised, the Warrant Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon such expiration (or such cancellation or
          retirement, as the case may be), be recomputed as
          if:

                    (i)  in the case of Options for Common
               Stock or Convertible Securities, the only
               Additional Shares of Common Stock issued or
               sold were the Additional Shares of Common
               Stock, if any, actually issued or sold upon the
               exercise of such Options or the conversion or
               exchange of such Convertible Securities and the
               consideration received therefor was the
               consideration actually received by the Company
               for the issue, sale, grant or assumption of all
               such Options, whether or not exercised, plus
               the consideration actually received by the
               Company upon such exercise, or for the issue or
               sale of all such Convertible Securities which
               were actually converted or exchanged, plus the
               additional consideration, if any, actually
               received by the Company upon such conversion or
               exchange, and

                    (ii) in the case of Options for
               Convertible Securities, only the Convertible
               Securities, if any, actually issued or sold
               upon the exercise of such Options were issued
               at the time of the issue, sale, grant or
               assumption of such Options, and the
               consideration received by the Company for the
               Additional Shares of Common Stock deemed to
               have then been issued was the consideration
               actually received by the Company for the issue,
               sale, grant or assumption of all such Options,
               whether or not exercised, plus the
               consideration deemed to have been received by
               the Company (pursuant to section 2.5) upon the
               issue or sale of such Convertible Securities
               with respect to which such Options were
               actually exercised;

               (d)  no readjustment pursuant to subdivision
          (b) or (c) above shall have the effect of increasing
          the Warrant Price by an amount in excess of the
          amount of the adjustment thereof originally made in
          respect of the issue, sale, grant or assumption of
          such Options or Convertible Securities; and 

               (e)  in the case of any such Options which
          expire by their terms not more than 30 days after
          the date of issue, sale, grant or assumption
          thereof, no adjustment of the Warrant Price shall be
          made until the expiration or exercise of all such
          Options, whereupon such adjustment shall be made in
          the manner provided in subdivision (c) above.

               2.4.  Treatment of Stock Dividends, Stock
     Splits, etc.  In case the Company at any time or from
     time to time after the date hereof shall declare or pay
     any dividend on the Common Stock payable in Common Stock,
     or shall effect a subdivision of the outstanding shares
     of Common Stock into a greater number of shares of Common
     Stock (by reclassification or otherwise than by payment
     of a dividend in Common Stock), then, and in each such
     case, Additional Shares of Common Stock shall be deemed
     to have been issued (a) in the case of any such dividend,
     immediately after the close of business on the record
     date for the determination of holders of any class of
     securities entitled to receive such dividend, or (b) in
     the case of any such subdivision, at the close of
     business on the day immediately prior to the day upon
     which such corporate action becomes effective.

               2.5.  Computation of Consideration.  For the
     purposes of this section 2,

               (a)  the consideration for the issue or sale of
          any Additional Shares of Common Stock shall,
          irrespective of the accounting treatment of such
          consideration,

                    (i)  insofar as it consists of cash, be
               computed at the net amount of cash received by
               the Company, without deducting any expenses
               paid or incurred by the Company or any
               commissions or compensation paid or concessions
               or discounts allowed to underwriters, dealers
               or others performing similar services in
               connection with such issue or sale,

                    (ii)  insofar as it consists of property
               (including securities) other than cash, be
               computed at the fair value thereof at the time
               of such issue or sale, as determined in good
               faith by the Board of Directors of the Company
               (subject to  confirmation by a firm of
               independent certified public accountants of
               recognized  standing approved by Wand/Nestor
               Investments L.P.), and 

                    (iii)  in case Additional Shares of Common
               Stock are issued or sold together with other
               stock or securities or other assets of the
               Company for a consideration which covers both,
               be the portion of such consideration so
               received, computed as provided in clauses (i)
               and (ii) above, allocable to such Additional
               Shares of Common Stock, all as determined in
               good faith by the Board of Directors of the
               Company (subject to  confirmation by a firm of
               independent certified public accountants of
               recognized  standing approved by Wand/Nestor
               Investments L.P.);

               (b)  Additional Shares of Common Stock deemed
          to have been issued pursuant to section 2.3,
          relating to Options and Convertible Securities,
          shall be deemed to have been issued for a
          consideration per share determined by dividing

                    (i)  the total amount, if any, received
               and receivable by the Company as consideration
               for the issue, sale, grant or assumption of the
               Options or Convertible Securities in question,
               plus the minimum aggregate amount of additional
               consideration (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such consideration to protect
               against dilution) payable to the Company upon
               the exercise in full of such Options or the
               conversion or exchange of such Convertible
               Securities or, in the case of Options for
               Convertible Securities, the exercise of such
               Options for Convertible Securities and the
               conversion or exchange of such Convertible
               Securities, in each case computing such
               consideration as provided in the foregoing
               subdivision (a),

     by

                    (ii)  the maximum number of shares of
               Common Stock (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such number to protect against
               dilution) issuable upon the exercise of such
               Options or the conversion or exchange of such
               Convertible Securities; and

               (c)  Additional Shares of Common Stock deemed
          to have been issued pursuant to section 2.4,
          relating to stock dividends, stock splits, etc.,
          shall be deemed to have been issued for no
          consideration.

               2.6.  Adjustments for Combinations, etc.  In
     case the outstanding shares of Common Stock shall be
     combined or consolidated, by reclassification or
     otherwise, into a lesser number of shares of Common
     Stock, the Warrant Price in effect immediately prior to
     such combination or consolidation shall, concurrently
     with the effectiveness of such combination or
     consolidation, be proportionately increased.

               2.7.  Dilution in Case of Other Securities.  In
     case any Other Securities shall be issued or sold or
     shall become subject to issue or sale upon the conversion
     or exchange of any stock (or Other Securities) of the
     Company (or any issuer of Other Securities or any other
     Person referred to in section 3) or to subscription,
     purchase or other acquisition pursuant to any Options
     issued or granted by the Company (or any such other
     issuer or Person) for a consideration such as to dilute,
     on a basis consistent with the standards established in
     the other provisions of this section 2, the purchase
     rights granted by this Warrant, then, and in each such
     case, the computations, adjustments and readjustments
     provided for in this section 2 with respect to the
     Warrant Price shall be made as nearly as possible in the
     manner so provided and applied to determine the amount of
     Other Securities from time to time receivable upon the
     exercise of the Warrants, so as to protect the holders of
     the Warrants against the effect of such dilution.

               2.8.  Minimum Adjustment of Warrant Price.  If
     the amount of any adjustment of the Warrant Price
     required pursuant to this section 2 would be less than
     one percent (1%) of the Warrant Price in effect at the
     time such adjustment is otherwise so required to be made,
     such amount shall be carried forward and adjustment with
     respect thereto made at the time of and together with any
     subsequent adjustment which, together with such amount
     and any other amount or amounts so carried forward, shall
     aggregate at least one percent (1%) of such Warrant
     Price.

               3.  Consolidation, Merger, etc.  3.1.  
     Adjustments for Consolidation, Merger, Sale of Assets,
     Reorganization, etc.  In case the Company after the date
     hereof (a) shall consolidate with or merge into any other
     Person and shall not be the continuing or surviving
     corporation of such consolidation or merger, or (b) shall
     permit any other Person to consolidate with or merge into
     the Company and the Company shall be the continuing or
     surviving Person but, in connection with such
     consolidation or merger, the Common Stock or Other
     Securities shall be changed into or exchanged for stock
     or other securities of any other Person or cash or any
     other property, or (c) shall transfer all or
     substantially all of its properties or assets to any
     other Person, or (d) shall effect a capital
     reorganization or reclassification of the Common Stock or
     Other Securities (other than a capital reorganization or
     reclassification resulting in the issue of Additional
     Shares of Common Stock for which adjustment in the
     Warrant Price is provided in section 2.2.1 or 2.2.2),
     then, and in the case of each such transaction, proper
     provision shall be made so that, upon the basis and the
     terms and in the manner provided in this Warrant, the
     holder of this Warrant, upon the exercise hereof at any
     time after the consummation of such transaction, shall be
     entitled to receive (at the aggregate Warrant Price in
     effect at the time of such consummation for all Common
     Stock or Other Securities issuable upon such exercise
     immediately prior to such consummation), in lieu of the
     Common Stock or Other Securities issuable upon such
     exercise prior to such consummation, the highest amount
     of securities, cash or other property to which such
     holder would actually have been entitled as a shareholder
     upon such consummation if such holder had exercised the
     rights represented by this Warrant immediately prior
     thereto, subject to adjustments (subsequent to such
     consummation) as nearly equivalent as possible to the
     adjustments provided for in sections 2 through 4.

               3.2.  Assumption of Obligations. 
     Notwithstanding anything contained in the Warrants or in
     the Purchase Agreement to the contrary, the Company will
     not effect any of the transactions described in clauses
     (a) through (d) of section 3.1 unless, prior to the
     consummation thereof, each Person (other than the
     Company) which may be required to deliver any stock,
     securities, cash or property upon the exercise of this
     Warrant as provided herein shall assume, by written
     instrument delivered to, and reasonably satisfactory to,
     the holder of this Warrant, (a) the obligations of the
     Company under this Warrant (and if the Company shall
     survive the consummation of such transaction, such
     assumption shall be in addition to, and shall not release
     the Company from, any continuing obligations of the
     Company under this Warrant), (b) the obligations of the
     Company under the Registration Rights Agreement and (c)
     the obligation to deliver to such holder such shares of
     stock, securities, cash or property as, in accordance
     with the foregoing provisions of this section 3, such
     holder may be entitled to receive, and such Person shall
     have similarly delivered to such holder an opinion of
     counsel for such Person, which counsel shall be
     reasonably satisfactory to such holder, stating that this
     Warrant shall thereafter continue in full force and
     effect and the terms hereof (including, without
     limitation, all of the provisions of this section 3)
     shall be applicable to the stock, securities, cash or
     property which such Person may be required to deliver
     upon any exercise of this Warrant or the exercise of any
     rights pursuant hereto.

               4.  Other Dilutive Events.  In case any event
     shall occur as to which the provisions of section 2 or
     section 3 are not strictly applicable but the failure to
     make any adjustment would not fairly protect the purchase
     rights represented by this Warrant in accordance with the
     essential intent and principles of such sections, then,
     in each such case, the Company shall appoint a firm of
     independent certified public accountants of recognized
     national standing (such firm to be subject to the
     approval of Wand/Nestor Investments L.P.), which shall
     give their opinion regarding the adjustment, if any, on a
     basis consistent with the essential intent and principles
     established in sections 2 and 3, necessary to preserve,
     without dilution, the purchase rights represented by this
     Warrant.  Upon receipt of such opinion, the Company will
     promptly mail a copy thereof to the holder of this
     Warrant and shall make the adjustments described therein.

               5.  No Dilution or Impairment.  The Company
     will not, by amendment of its certificate of
     incorporation or through any consolidation, merger,
     reorganization, transfer of assets, dissolution, issue or
     sale of securities or any other voluntary action, avoid
     or seek to avoid the observance or performance of any of
     the terms of this Warrant, but will at all times in good
     faith assist in the carrying out of all such terms and in
     the taking of all such action as may be necessary or
     appropriate in order to protect the rights of the holder
     of this Warrant against dilution or other impairment. 
     Without limiting the generality of the foregoing, the
     Company (a) will not permit the par value of any shares
     of stock receivable upon the exercise of this Warrant to
     exceed the amount payable therefor upon such exercise,
     (b) will take all such action as may be necessary or
     appropriate in order that the Company may validly and
     legally issue fully paid and nonassessable shares of
     stock on the exercise of the Warrants from time to time
     outstanding, and (c) will not take any action which
     results in any adjustment of the Warrant Price if the
     total number of shares of Common Stock (or Other
     Securities) issuable after the action upon the exercise
     of all of the Warrants would exceed the total number of
     shares of Common Stock (or Other Securities) then
     authorized by the Company's certificate of incorporation
     and available for the purpose of issue upon such
     exercise.

               6.  Accountants' Report as to Adjustments.  In
     each case of any adjustment or readjustment in the shares
     of Common Stock (or Other Securities) issuable upon the
     exercise of this Warrant, the Company at its expense will
     promptly compute such adjustment or readjustment in
     accordance with the terms of this Warrant and cause
     independent certified public accountants of recognized
     standing (such firm to be subject to the approval of
     Wand/Nestor Investments L.P.) selected by the Company to
     verify such computation and prepare a report setting
     forth such adjustment or readjustment and showing in
     reasonable detail the method of calculation thereof and
     the facts upon which such adjustment or readjustment is
     based, including a statement of (a) the consideration
     received or to be received by the Company for any
     Additional Shares of Common Stock issued or sold or
     deemed to have been issued, (b) the number of shares of
     Common Stock outstanding or deemed to be outstanding, and
     (c) the Warrant Price in effect immediately prior to such
     issue or sale and as adjusted and readjusted (if required
     by section 2) on account thereof.  The Company will
     forthwith mail a copy of each such report to each holder
     of a Warrant and will, upon the written request at any
     time of any holder of a Warrant, furnish to such holder a
     like report setting forth the Warrant Price at the time
     in effect and showing in reasonable detail how it was
     calculated.  The Company will also keep copies of all
     such reports at its principal office and will cause the
     same to be available for inspection at such office during
     normal business hours by any holder of a Warrant or any
     prospective purchaser of a Warrant designated by the
     holder thereof.

               7.  Notices of Corporate Action.  In the event of
               (a)  any taking by the Company of a record of
          the holders of any class of securities for the
          purpose of determining the holders thereof who are
          entitled to receive any dividend (other than a
          regular periodic dividend payable in cash out of
          earned surplus in an amount not exceeding the amount
          of the immediately preceding cash dividend for such
          period) or other distribution, or any right to
          subscribe for, purchase or otherwise acquire any
          shares of stock of any class or any other securities
          or property, or to receive any other right, or 

               (b)  any capital reorganization of the Company,
          any reclassification or recapitalization of the
          capital stock of the Company or any consolidation or
          merger involving the Company and any other Person or
          any transfer of all or substantially all the assets
          of the Company to any other Person, or

               (c)  any voluntary or involuntary dissolution,
          liquidation or winding-up of the Company,

     the Company will mail to each holder of a Warrant a
     notice specifying (i) the date or expected date on which
     any such record is to be taken for the purpose of such
     dividend, distribution or right, and the amount and
     character of such dividend, distribution or right, and
     (ii) the date or expected date on which any such
     reorganization, reclassification, recapitalization,
     consolidation, merger, transfer, dissolution, liquidation
     or winding-up is to take place and the time, if any such
     time is to be fixed, as of which the holders of record of
     Common Stock (or Other Securities) shall be entitled to
     exchange their shares of Common Stock (or Other
     Securities) for the securities or other property
     deliverable upon such reorganization, reclassification,
     recapitalization, consolidation, merger, transfer,
     dissolution, liquidation or winding-up.  Such notice
     shall be mailed at least 45 days prior to the date
     therein specified.

               8.  Registration of Common Stock.  If any
     shares of Common Stock required to be reserved for
     purposes of exercise of this Warrant require registration
     with or approval of any governmental authority under any
     federal or state law (other than the Securities Act)
     before such shares may be issued upon exercise, the
     Company will, at its expense and as expeditiously as
     possible, use its best efforts to cause such shares to be
     duly registered or approved, as the case may be.  The
     shares of Common Stock (and Other Securities) issuable
     upon exercise of this Warrant (or upon conversion of any
     shares of Common Stock issued upon such exercise) shall
     constitute Registrable Securities (as such term is
     defined in the Registration Rights Agreement).  Each
     holder of this Warrant shall be entitled to all of the
     benefits afforded to a holder of any such Registrable
     Securities under the Registration Rights Agreement and
     such holder, by its acceptance of this Warrant, agrees to
     be bound by and to comply with the terms and conditions
     of the Registration Rights Agreement applicable to such
     holder as a holder of such Registrable Securities.  At
     any such time as Common Stock is listed on any national
     securities exchange, the Company will, at its expense,
     obtain promptly and maintain the approval for listing on
     each such exchange, upon official notice of issuance, the
     shares of Common Stock issuable upon exercise of the then
     outstanding Warrants and maintain the listing of such
     shares after their issuance; and the Company will also
     list on such national securities exchange, will register
     under the Exchange Act and will maintain such listing of,
     any Other Securities that at any time are issuable upon
     exercise of the Warrants, if and at the time that any
     securities of the same class shall be listed on such
     national securities exchange by the Company.

               9.  Restrictions on Transfer.  9.1. 
     Restrictive Legends.  Except as otherwise permitted by
     this section 9, each Warrant (including each Warrant
     issued upon the transfer of any Warrant) shall be stamped
     or otherwise imprinted with a legend in substantially the
     following form:

          SECURITIES LAWS AND REGULATIONS AND CERTAIN

     issued upon the transfer of any such Common Stock (or

          AGREEMENT IS ON FILE WITH THE SECRETARY OF THE

               10.  Availability of Information.  The Company
     shall timely file the reports required to be filed by it
     under the Securities Act and the Exchange Act (including
     but not limited to the reports under sections 13 and
     15(d) of the Exchange Act referred to in subparagraph (c)
     of Rule 144 adopted by the Commission under the
     Securities Act) and the rules and regulations adopted by
     the Commission thereunder (or, if the Company is not
     required to file such reports, will, upon the request of
     any holder of Registrable Securities, make publicly
     available other information) and will take such further
     action as any holder of Registrable Securities may
     reasonably request, all to the extent required from time
     to time to enable such holder to sell Registrable
     Securities without registration under the Securities Act
     within the limitation of the exemptions provided by (a)
     Rule 144 under the Securities Act, as such Rule may be
     amended from time to time, or (b) any similar rule or
     regulation hereafter adopted by the Commission.  Upon the
     request of any holder of Registrable Securities, the
     Company will deliver to such holder a written statement
     as to whether it has complied with the requirements of
     this section 10.

               11.  Reservation of Stock, etc.  The Company
     will at all times reserve and keep available, solely for
     issuance and delivery upon exercise of the Warrants, the
     number of shares of Common Stock (or Other Securities)
     from time to time issuable upon exercise of all Warrants
     at the time outstanding.  All shares of Common Stock (or
     Other Securities) issuable upon exercise of any Warrants
     shall be duly authorized and, when issued upon such
     exercise, shall be validly issued and, in the case of
     shares, fully paid and nonassessable with no liability on
     the part of the holders thereof.

               12.  Registration and Transfer of Warrants,
     etc.

               12.1. Warrant Register; Ownership of Warrants. 
     The Company will keep at its principal office a register
     in which the Company will provide for the registration of
     Warrants and the registration of transfers of Warrants. 
     The Company may treat the Person in whose name any
     Warrant is registered on such register as the owner
     thereof for all other purposes, and the Company shall not
     be affected by any notice to the contrary, except that,
     if and when any Warrant is properly assigned in blank,
     the Company may (but shall not be obligated to) treat the
     bearer thereof as the owner of such Warrant for all
     purposes.  Subject to section 9, a Warrant, if properly
     assigned, may be exercised by a new holder without a new
     Warrant first having been issued.

               12.2.  Transfer and Exchange of Warrants.  Upon
     surrender of any Warrant for registration of transfer or
     for exchange to the Company at its principal office, the
     Company at its expense will (subject to compliance with
     section 9, if applicable) execute and deliver in exchange
     therefor a new Warrant or Warrants of like tenor, in the
     name of such holder or as such holder (upon payment by
     such holder of any applicable transfer taxes) may direct,
     calling in the aggregate on the face or faces thereof for
     the number of shares of Common Stock called for on the
     face or faces of the Warrant or Warrants so surrendered. 

               12.3.  Replacement of Warrants.  Upon receipt
     of evidence reasonably satisfactory to the Company of the
     loss, theft, destruction or mutilation of any Warrant
     and, in the case of any such loss, theft or destruction
     of any Warrant, upon delivery of an indemnity bond in
     such reasonable amount as the Company may determine or,
     in the case of any such mutilation, upon the surrender of
     such Warrant for cancellation to the Company at its
     principal office, the Company at its expense will execute
     and deliver, in lieu thereof, a new Warrant of like
     tenor.  

               13.  Registration Rights.  The Purchaser or any
     assignee of this Warrant shall be entitled to all rights
     and benefits regarding the registration of Common Stock
     and Registrable Securities set forth in the Registration
     Rights Agreement.

                                        Wand I Regular Warrant

                            NESTOR, INC.

                   Common Stock Purchase Warrant

                                            New York, New York
     No. W-U                                  January 31, 1996

               Nestor, Inc. (the "Company"), a Delaware
     corporation, for value received, hereby certifies that
     Wand/Nestor Investments L.P. ("Wand"), or registered
     assigns, is entitled to purchase from the Company 152,830
     duly authorized, validly issued, fully paid and
     nonassessable shares of Common Stock, par value $.01 per
     share (the "Common Stock"), of the Company at the
     purchase price per share of $1.25 (provided, however, if
     the Company has not on or before July 31, 1996 entered
     into a definitive agreement with a party with which it is
     currently negotiating, such agreement to contemplate an
     ongoing revenue stream to the Company, based on
     commercial exploitation of the Company's technology, and
     to require a payment to the Company upon execution of at
     least $1.25 million, such payment to be not primarily in
     consideration of any requirement that the Company render
     services, then the purchase price shall automatically be
     reduced to $.75), at any time or from time to time prior
     to 5:00 P.M., New York City time, on August 1, 2004 (or
     such later date as may be determined pursuant to section
     19), all subject to the terms, conditions and adjustments
     set forth below in this Warrant.

               This Warrant is being issued by the Company in
     consideration of Wand's performance of its obligations
     pursuant to the Securities Purchase and Exchange
     Agreement dated as of January 31, 1996 by and between the
     Company and Wand (the "Purchase and Exchange Agreement"). 
     Certain capitalized terms used in this Warrant are
     defined in section 14; references to an "Exhibit" are,
     unless otherwise specified, to one of the Exhibits
     attached to this Warrant and references to a "section"
     are, unless otherwise specified, to one of the sections
     of this Warrant.

               1.  Exercise of Warrant.  

               1.1.  Manner of Exercise.  This Warrant may be
     exercised after June 30, 1996 by the holder hereof, in
     whole or in part, during normal business hours on any
     Business Day, by surrender of this Warrant to the Company
     at its principal office, accompanied by a subscription 
     substantially in the form attached to this Warrant (or a
     reasonable facsimile thereof) duly executed by such
     holder and accompanied by payment, in cash, by certified
     or official bank check payable to the order of the
     Company, or in the manner provided in Section 1.5, in the
     amount obtained by multiplying (a) the number of shares
     of Common Stock (without giving effect to any adjustment
     thereof) designated in such subscription by (b) $1.25
     (provided, however, if the Company has not on or before
     July 31, 1996 entered into a definitive agreement with a
     party with which it is currently negotiating, such
     agreement to contemplate an ongoing revenue stream to the
     Company, based on commercial exploitation of the
     Company's technology, and to require a payment to the
     Company upon execution of at least $1.25 million, such
     payment to be not primarily in consideration of any
     requirement that the Company render services, then the
     purchase price shall automatically be reduced to $.75),
     and such holder shall thereupon be entitled to receive
     the number of duly authorized, validly issued, fully paid
     and nonassessable shares of Common Stock (or Other
     Securities) determined as provided in sections 2 through
     4.

               1.2.  When Exercise Effective.  Each exercise
     of this Warrant shall be deemed to have been effected
     immediately prior to the close of business on the
     Business Day on which this Warrant shall have been
     surrendered to the Company as provided in section 1.1,
     and at such time the Person or Persons in whose name or
     names any certificate or certificates for shares of
     Common Stock (or Other Securities) shall be issuable upon
     such exercise as provided in section 1.3 shall be deemed
     to have become the holder or holders of record thereof.

               1.3.  Delivery of Stock Certificates, etc.  As
     soon as practicable after each exercise of this Warrant,
     in whole or in part, and in any event within five
     Business Days thereafter, the Company at its expense
     (including the payment by it of any applicable issue
     taxes) will cause to be issued in the name of and
     delivered to the holder hereof or, subject to section 9,
     as such holder (upon payment by such holder of any
     applicable transfer taxes) may direct,

               (a)  a certificate or certificates for the
          number of duly authorized, validly issued, fully
          paid and nonassessable shares of Common Stock (or
          Other Securities) to which such holder shall be
          entitled upon such exercise plus, in lieu of any
          fractional share to which such holder would
          otherwise be entitled, cash in an amount equal to
          the same fraction of the Market Price per share on
          the Business Day next preceding the date of such
          exercise, and

               (b)  in case such exercise is in part only, a
          new Warrant or Warrants of like tenor, calling in
          the aggregate on the face or faces thereof for the
          number of shares of Common Stock equal (without
          giving effect to any adjustment thereof) to the
          number of such shares called for on the face of this
          Warrant minus the number of such shares designated
          by the holder upon such exercise as provided in
          section 1.1.

               1.4.  Company to Reaffirm Obligations.  The
     Company will, at the time of each exercise of this
     Warrant, upon the request of the holder hereof,
     acknowledge in writing its continuing obligation to
     afford to such holder all rights (including, without
     limitation, any rights to registration, pursuant to the
     Registration Rights Agreement referred to in section 8,
     of the shares of Common Stock or Other Securities issued
     upon such exercise) to which such holder shall continue
     to be entitled after such exercise in accordance with the
     terms of this Warrant, provided that if the holder of
     this Warrant shall fail to make any such request, such
     failure shall not affect the continuing obligation of the
     Company to afford such rights to such holder.

               1.5.  Payment by Application of Shares
     Otherwise Issuable.  Upon any exercise of this Warrant,
     the holder hereof may, at its option, instruct the
     Company, by written notice accompanying the surrender of
     this Warrant at the time of such exercise, to apply to
     the payment required by section 1.1 such number of the
     shares of Common Stock otherwise issuable to such holder
     upon such exercise as shall be specified in such notice,
     in which case an amount equal to the excess of the
     aggregate Current Market Price of such specified number
     of shares on the date of exercise over the portion of the
     payment required by section 1.1 attributable to such
     shares shall be deemed to have been paid to the Company
     and the number of shares issuable upon such exercise
     shall be reduced by such specified number.

               2.  Adjustment of Common Stock Issuable Upon
     Exercise.  

               2.1.  General; Warrant Price.  The number of
     shares of Common Stock which the holder of this Warrant
     shall be entitled to receive upon each exercise hereof
     shall be determined by multiplying the number of shares
     of Common Stock which would otherwise (but for the
     provisions of this section 2) be issuable upon such
     exercise, as designated by the holder hereof pursuant to
     section 1.1, by the fraction of which (a) the numerator
     is the price then applicable pursuant to section 1.1(b)
     of this Warrant and (b) the denominator is the Warrant
     Price in effect on the date of such exercise.  The
     "Warrant Price" shall initially be $1.25 per share,
     provided, however, if the Company has not on or before
     July 31, 1996 entered into a definitive agreement with a
     party with which it is currently negotiating, such
     agreement to contemplate an ongoing revenue stream to the
     Company, based on commercial exploitation of the
     Company's technology, and to require a payment to the
     Company upon execution of at least $1.25 million, such
     payment to be not primarily in consideration of any
     requirement that the Company render services, then the
     Warrant Price shall automatically be reduced to $.75. 
     The Warrant Price shall be adjusted and readjusted from
     time to time as further provided in this section 2 and,
     as so adjusted or readjusted, shall remain in effect
     until a further adjustment or readjustment thereof is
     required by this section 2.

               2.2.  Adjustment of Warrant Price.

               2.2.1  Issuance of Additional Shares of Common
     Stock.  In case the Company at any time or from time to
     time after the date hereof shall issue or sell Additional
     Shares of Common Stock (including Additional Shares of
     Common Stock deemed to be issued pursuant to section 2.3
     or 2.4) without consideration or for a consideration per
     share less than the Warrant Price in effect immediately
     prior to such issue or sale, then, and in each such case,
     subject to section 2.8, such Warrant Price shall be
     reduced, concurrently with such issue or sale, to a price
     (calculated to the nearest .001 of a cent) equal to the
     consideration per share paid for such Additional Shares
     of Common Stock.

               2.2.2  Extraordinary Dividends and
     Distributions.  In case the Company at any time or from
     time to time after the date hereof shall declare, order,
     pay or make a dividend or other distribution (including,
     without limitation, any distribution of other or
     additional stock or other securities or property or
     Options by way of dividend or spin-off, reclassification,
     recapitalization or similar corporate rearrangement) on
     the Common Stock, other than a dividend payable in (a)
     Additional Shares of Common Stock or (b) cash dividends
     during any fiscal year of the Company that do not exceed
     twenty percent (20%) of the after tax earnings per share
     of the Common Stock for the immediately preceding fiscal
     year of the Company, then, and in each such case, subject
     to section 2.8, the Warrant Price in effect immediately
     prior to the close of business on the record date fixed
     for the determination of holders of any class of
     securities entitled to receive such dividend or
     distribution shall be reduced, effective as of the close
     of business on such record date, to a price (calculated
     to the nearest .001 of a cent) determined by multiplying
     such Warrant Price by a fraction

               (x)  the numerator of which shall be the
          Current Market Price in effect on such record date
          or, if the Common Stock trades on an ex-dividend
          basis, on the date prior to the commencement of ex-
          dividend trading, less the amount of such dividend
          or distribution (as determined in good faith by the
          Board of Directors of the Company, subject to 
          confirmation by a firm of independent certified
          public accountants of recognized national standing
          approved by Wand/Nestor Investments L.P.) applicable
          to one share of Common Stock, and

               (y)  the denominator of which shall be such
          Current Market Price.

               2.3.  Treatment of Options and Convertible
     Securities.  In case the Company at any time or from time
     to time after the date hereof shall issue, sell, grant or
     assume, or shall fix a record date for the determination
     of holders of any class of securities entitled to
     receive, any Options or Convertible Securities, then, and
     in each such case, the maximum number of Additional
     Shares of Common Stock (as set forth in the instrument
     relating thereto, without regard to any provisions
     contained therein for a subsequent adjustment of such
     number) issuable upon the exercise of such Options or, in
     the case of Convertible Securities and Options therefor,
     the conversion or exchange of such Convertible
     Securities, shall be deemed to be Additional Shares of
     Common Stock issued as of the time of such issue, sale,
     grant or assumption or, in case such a record date shall
     have been fixed, as of the close of business on such
     record date (or, if the Common Stock trades on an ex-
     dividend basis, on the date prior to the commencement of
     ex-dividend trading), provided that such Additional
     Shares of Common Stock shall not be deemed to have been
     issued unless the consideration per share (determined
     pursuant to section 2.5) of such shares would be less
     than the Warrant Price in effect on the date of and
     immediately prior to such issue, sale, grant or
     assumption or immediately prior to the close of business
     on such record date (or, if the Common Stock trades on an
     ex-dividend basis, on the date prior to the commencement
     of ex-dividend trading), as the case may be, and
     provided, further, that in any such case in which
     Additional Shares of Common Stock are deemed to be issued

               (a)  no further adjustment of the Warrant Price
          shall be made upon the subsequent issue or sale of
          Convertible Securities or shares of Common Stock
          upon the exercise of such Options or the conversion
          or exchange of such Convertible Securities;

               (b)  if such Options or Convertible Securities
          by their terms provide, with the passage of time or
          otherwise, for any increase in the consideration
          payable to the Company, or decrease in the number of
          Additional Shares of Common Stock issuable, upon the
          exercise, conversion or exchange thereof (by change
          of rate or otherwise), the Warrant Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon any such increase or decrease becoming
          effective, be recomputed to reflect such increase or
          decrease insofar as it affects such Options, or the
          rights of conversion or exchange under such
          Convertible Securities, which are outstanding at
          such time;

               (c)  upon the expiration (or purchase by the
          Company and cancellation or retirement) of any such
          Options which shall not have been exercised or the
          expiration of any rights of conversion or exchange
          under any such Convertible Securities which (or
          purchase by the Company and cancellation or
          retirement of any such Convertible Securities the
          rights of conversion or exchange under which) shall
          not have been exercised, the Warrant Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon such expiration (or such cancellation or
          retirement, as the case may be), be recomputed as
          if:

                    (i)  in the case of Options for Common
               Stock or Convertible Securities, the only
               Additional Shares of Common Stock issued or
               sold were the Additional Shares of Common
               Stock, if any, actually issued or sold upon the
               exercise of such Options or the conversion or
               exchange of such Convertible Securities and the
               consideration received therefor was the
               consideration actually received by the Company
               for the issue, sale, grant or assumption of all
               such Options, whether or not exercised, plus
               the consideration actually received by the
               Company upon such exercise, or for the issue or
               sale of all such Convertible Securities which
               were actually converted or exchanged, plus the
               additional consideration, if any, actually
               received by the Company upon such conversion or
               exchange, and

                    (ii) in the case of Options for
               Convertible Securities, only the Convertible
               Securities, if any, actually issued or sold
               upon the exercise of such Options were issued
               at the time of the issue, sale, grant or
               assumption of such Options, and the
               consideration received by the Company for the
               Additional Shares of Common Stock deemed to
               have then been issued was the consideration
               actually received by the Company for the issue,
               sale, grant or assumption of all such Options,
               whether or not exercised, plus the
               consideration deemed to have been received by
               the Company (pursuant to section 2.5) upon the
               issue or sale of such Convertible Securities
               with respect to which such Options were
               actually exercised;

               (d)  no readjustment pursuant to subdivision
          (b) or (c) above shall have the effect of increasing
          the Warrant Price by an amount in excess of the
          amount of the adjustment thereof originally made in
          respect of the issue, sale, grant or assumption of
          such Options or Convertible Securities; and 

               (e)  in the case of any such Options which
          expire by their terms not more than 30 days after
          the date of issue, sale, grant or assumption
          thereof, no adjustment of the Warrant Price shall be
          made until the expiration or exercise of all such
          Options, whereupon such adjustment shall be made in
          the manner provided in subdivision (c) above.

               2.4.  Treatment of Stock Dividends, Stock
     Splits, etc.  In case the Company at any time or from
     time to time after the date hereof shall declare or pay
     any dividend on the Common Stock payable in Common Stock,
     or shall effect a subdivision of the outstanding shares
     of Common Stock into a greater number of shares of Common
     Stock (by reclassification or otherwise than by payment
     of a dividend in Common Stock), then, and in each such
     case, Additional Shares of Common Stock shall be deemed
     to have been issued (a) in the case of any such dividend,
     immediately after the close of business on the record
     date for the determination of holders of any class of
     securities entitled to receive such dividend, or (b) in
     the case of any such subdivision, at the close of
     business on the day immediately prior to the day upon
     which such corporate action becomes effective.

               2.5.  Computation of Consideration.  For the
     purposes of this section 2,

               (a)  the consideration for the issue or sale of
          any Additional Shares of Common Stock shall,
          irrespective of the accounting treatment of such
          consideration,

                    (i)  insofar as it consists of cash, be
               computed at the net amount of cash received by
               the Company, without deducting any expenses
               paid or incurred by the Company or any
               commissions or compensation paid or concessions
               or discounts allowed to underwriters, dealers
               or others performing similar services in
               connection with such issue or sale,

                    (ii)  insofar as it consists of property
               (including securities) other than cash, be
               computed at the fair value thereof at the time
               of such issue or sale, as determined in good
               faith by the Board of Directors of the Company
               (subject to  confirmation by a firm of
               independent certified public accountants of
               recognized  standing approved by Wand/Nestor
               Investments L.P.), and 

                    (iii)  in case Additional Shares of Common
               Stock are issued or sold together with other
               stock or securities or other assets of the
               Company for a consideration which covers both,
               be the portion of such consideration so
               received, computed as provided in clauses (i)
               and (ii) above, allocable to such Additional
               Shares of Common Stock, all as determined in
               good faith by the Board of Directors of the
               Company (subject to  confirmation by a firm of
               independent certified public accountants of
               recognized  standing approved by Wand/Nestor
               Investments L.P.);

               (b)  Additional Shares of Common Stock deemed
          to have been issued pursuant to section 2.3,
          relating to Options and Convertible Securities,
          shall be deemed to have been issued for a
          consideration per share determined by dividing

                    (i)  the total amount, if any, received
               and receivable by the Company as consideration
               for the issue, sale, grant or assumption of the
               Options or Convertible Securities in question,
               plus the minimum aggregate amount of additional
               consideration (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such consideration to protect
               against dilution) payable to the Company upon
               the exercise in full of such Options or the
               conversion or exchange of such Convertible
               Securities or, in the case of Options for
               Convertible Securities, the exercise of such
               Options for Convertible Securities and the
               conversion or exchange of such Convertible
               Securities, in each case computing such
               consideration as provided in the foregoing
               subdivision (a),

     by

                    (ii)  the maximum number of shares of
               Common Stock (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such number to protect against
               dilution) issuable upon the exercise of such
               Options or the conversion or exchange of such
               Convertible Securities; and

               (c)  Additional Shares of Common Stock deemed
          to have been issued pursuant to section 2.4,
          relating to stock dividends, stock splits, etc.,
          shall be deemed to have been issued for no
          consideration.

               2.6.  Adjustments for Combinations, etc.  In
     case the outstanding shares of Common Stock shall be
     combined or consolidated, by reclassification or
     otherwise, into a lesser number of shares of Common
     Stock, the Warrant Price in effect immediately prior to
     such combination or consolidation shall, concurrently
     with the effectiveness of such combination or
     consolidation, be proportionately increased.

               2.7.  Dilution in Case of Other Securities.  In
     case any Other Securities shall be issued or sold or
     shall become subject to issue or sale upon the conversion
     or exchange of any stock (or Other Securities) of the
     Company (or any issuer of Other Securities or any other
     Person referred to in section 3) or to subscription,
     purchase or other acquisition pursuant to any Options
     issued or granted by the Company (or any such other
     issuer or Person) for a consideration such as to dilute,
     on a basis consistent with the standards established in
     the other provisions of this section 2, the purchase
     rights granted by this Warrant, then, and in each such
     case, the computations, adjustments and readjustments
     provided for in this section 2 with respect to the
     Warrant Price shall be made as nearly as possible in the
     manner so provided and applied to determine the amount of
     Other Securities from time to time receivable upon the
     exercise of the Warrants, so as to protect the holders of
     the Warrants against the effect of such dilution.

               2.8.  Minimum Adjustment of Warrant Price.  If
     the amount of any adjustment of the Warrant Price
     required pursuant to this section 2 would be less than
     one percent (1%) of the Warrant Price in effect at the
     time such adjustment is otherwise so required to be made,
     such amount shall be carried forward and adjustment with
     respect thereto made at the time of and together with any
     subsequent adjustment which, together with such amount
     and any other amount or amounts so carried forward, shall
     aggregate at least one percent (1%) of such Warrant
     Price.

               3.  Consolidation, Merger, etc.  

               3.1.   Adjustments for Consolidation, Merger,
     Sale of Assets, Reorganization, etc.  In case the Company
     after the date hereof (a) shall consolidate with or merge
     into any other Person and shall not be the continuing or
     surviving corporation of such consolidation or merger, or
     (b) shall permit any other Person to consolidate with or
     merge into the Company and the Company shall be the
     continuing or surviving Person but, in connection with
     such consolidation or merger, the Common Stock or Other
     Securities shall be changed into or exchanged for stock
     or other securities of any other Person or cash or any
     other property, or (c) shall transfer all or
     substantially all of its properties or assets to any
     other Person, or (d) shall effect a capital
     reorganization or reclassification of the Common Stock or
     Other Securities (other than a capital reorganization or
     reclassification resulting in the issue of Additional
     Shares of Common Stock for which adjustment in the
     Warrant Price is provided in section 2.2.1 or 2.2.2),
     then, and in the case of each such transaction, proper
     provision shall be made so that, upon the basis and the
     terms and in the manner provided in this Warrant, the
     holder of this Warrant, upon the exercise hereof at any
     time after the consummation of such transaction, shall be
     entitled to receive (at the aggregate Warrant Price in
     effect at the time of such consummation for all Common
     Stock or Other Securities issuable upon such exercise
     immediately prior to such consummation), in lieu of the
     Common Stock or Other Securities issuable upon such
     exercise prior to such consummation, the highest amount
     of securities, cash or other property to which such
     holder would actually have been entitled as a shareholder
     upon such consummation if such holder had exercised the
     rights represented by this Warrant immediately prior
     thereto, subject to adjustments (subsequent to such
     consummation) as nearly equivalent as possible to the
     adjustments provided for in sections 2 through 4.

               3.2.  Assumption of Obligations. 
     Notwithstanding anything contained in the Warrants or in
     the Purchase Agreement to the contrary, the Company will
     not effect any of the transactions described in clauses
     (a) through (d) of section 3.1 unless, prior to the
     consummation thereof, each Person (other than the
     Company) which may be required to deliver any stock,
     securities, cash or property upon the exercise of this
     Warrant as provided herein shall assume, by written
     instrument delivered to, and reasonably satisfactory to,
     the holder of this Warrant, (a) the obligations of the
     Company under this Warrant (and if the Company shall
     survive the consummation of such transaction, such
     assumption shall be in addition to, and shall not release
     the Company from, any continuing obligations of the
     Company under this Warrant), (b) the obligations of the
     Company under the Registration Rights Agreement and (c)
     the obligation to deliver to such holder such shares of
     stock, securities, cash or property as, in accordance
     with the foregoing provisions of this section 3, such
     holder may be entitled to receive, and such Person shall
     have similarly delivered to such holder an opinion of
     counsel for such Person, which counsel shall be
     reasonably satisfactory to such holder, stating that this
     Warrant shall thereafter continue in full force and
     effect and the terms hereof (including, without
     limitation, all of the provisions of this section 3)
     shall be applicable to the stock, securities, cash or
     property which such Person may be required to deliver
     upon any exercise of this Warrant or the exercise of any
     rights pursuant hereto.

               4.  Other Dilutive Events.  In case any event
     shall occur as to which the provisions of section 2 or
     section 3 are not strictly applicable but the failure to
     make any adjustment would not fairly protect the purchase
     rights represented by this Warrant in accordance with the
     essential intent and principles of such sections, then,
     in each such case, the Company shall appoint a firm of
     independent certified public accountants of recognized
     national standing (such firm to be subject to the
     approval of Wand/Nestor Investments L.P.), which shall
     give their opinion regarding the adjustment, if any, on a
     basis consistent with the essential intent and principles
     established in sections 2 and 3, necessary to preserve,
     without dilution, the purchase rights represented by this
     Warrant.  Upon receipt of such opinion, the Company will
     promptly mail a copy thereof to the holder of this
     Warrant and shall make the adjustments described therein.

               5.  No Dilution or Impairment.  The Company
     will not, by amendment of its certificate of
     incorporation or through any consolidation, merger,
     reorganization, transfer of assets, dissolution, issue or
     sale of securities or any other voluntary action, avoid
     or seek to avoid the observance or performance of any of
     the terms of this Warrant, but will at all times in good
     faith assist in the carrying out of all such terms and in
     the taking of all such action as may be necessary or
     appropriate in order to protect the rights of the holder
     of this Warrant against dilution or other impairment. 
     Without limiting the generality of the foregoing, the
     Company (a) will not permit the par value of any shares
     of stock receivable upon the exercise of this Warrant to
     exceed the amount payable therefor upon such exercise,
     (b) will take all such action as may be necessary or
     appropriate in order that the Company may validly and
     legally issue fully paid and nonassessable shares of
     stock on the exercise of the Warrants from time to time
     outstanding, and (c) will not take any action which
     results in any adjustment of the Warrant Price if the
     total number of shares of Common Stock (or Other
     Securities) issuable after the action upon the exercise
     of all of the Warrants would exceed the total number of
     shares of Common Stock (or Other Securities) then
     authorized by the Company's certificate of incorporation
     and available for the purpose of issue upon such
     exercise.

               6.  Accountants' Report as to Adjustments.  In
     each case of any adjustment or readjustment in the shares
     of Common Stock (or Other Securities) issuable upon the
     exercise of this Warrant, the Company at its expense will
     promptly compute such adjustment or readjustment in
     accordance with the terms of this Warrant and cause
     independent certified public accountants of recognized
     standing (such firm to be subject to the approval of
     Wand/Nestor Investments L.P.) selected by the Company to
     verify such computation and prepare a report setting
     forth such adjustment or readjustment and showing in
     reasonable detail the method of calculation thereof and
     the facts upon which such adjustment or readjustment is
     based, including a statement of (a) the consideration
     received or to be received by the Company for any
     Additional Shares of Common Stock issued or sold or
     deemed to have been issued, (b) the number of shares of
     Common Stock outstanding or deemed to be outstanding, and
     (c) the Warrant Price in effect immediately prior to such
     issue or sale and as adjusted and readjusted (if required
     by section 2) on account thereof.  The Company will
     forthwith mail a copy of each such report to each holder
     of a Warrant and will, upon the written request at any
     time of any holder of a Warrant, furnish to such holder a
     like report setting forth the Warrant Price at the time
     in effect and showing in reasonable detail how it was
     calculated.  The Company will also keep copies of all
     such reports at its principal office and will cause the
     same to be available for inspection at such office during
     normal business hours by any holder of a Warrant or any
     prospective purchaser of a Warrant designated by the
     holder thereof.

               7.  Notices of Corporate Action.  In the event of
               (a)  any taking by the Company of a record of
          the holders of any class of securities for the
          purpose of determining the holders thereof who are
          entitled to receive any dividend (other than a
          regular periodic dividend payable in cash out of
          earned surplus in an amount not exceeding the amount
          of the immediately preceding cash dividend for such
          period) or other distribution, or any right to
          subscribe for, purchase or otherwise acquire any
          shares of stock of any class or any other securities
          or property, or to receive any other right, or 

               (b)  any capital reorganization of the Company,
          any reclassification or recapitalization of the
          capital stock of the Company or any consolidation or
          merger involving the Company and any other Person or
          any transfer of all or substantially all the assets
          of the Company to any other Person, or

               (c)  any voluntary or involuntary dissolution,
          liquidation or winding-up of the Company,

     the Company will mail to each holder of a Warrant a
     notice specifying (i) the date or expected date on which
     any such record is to be taken for the purpose of such
     dividend, distribution or right, and the amount and
     character of such dividend, distribution or right, and
     (ii) the date or expected date on which any such
     reorganization, reclassification, recapitalization,
     consolidation, merger, transfer, dissolution, liquidation
     or winding-up is to take place and the time, if any such
     time is to be fixed, as of which the holders of record of
     Common Stock (or Other Securities) shall be entitled to
     exchange their shares of Common Stock (or Other
     Securities) for the securities or other property
     deliverable upon such reorganization, reclassification,
     recapitalization, consolidation, merger, transfer,
     dissolution, liquidation or winding-up.  Such notice
     shall be mailed at least 45 days prior to the date
     therein specified.

               8.  Registration of Common Stock.  If any
     shares of Common Stock required to be reserved for
     purposes of exercise of this Warrant require registration
     with or approval of any governmental authority under any
     federal or state law (other than the Securities Act)
     before such shares may be issued upon exercise, the
     Company will, at its expense and as expeditiously as
     possible, use its best efforts to cause such shares to be
     duly registered or approved, as the case may be.  The
     shares of Common Stock (and Other Securities) issuable
     upon exercise of this Warrant (or upon conversion of any
     shares of Common Stock issued upon such exercise) shall
     constitute Registrable Securities (as such term is
     defined in the Registration Rights Agreement).  Each
     holder of this Warrant shall be entitled to all of the
     benefits afforded to a holder of any such Registrable
     Securities under the Registration Rights Agreement and
     such holder, by its acceptance of this Warrant, agrees to
     be bound by and to comply with the terms and conditions
     of the Registration Rights Agreement applicable to such
     holder as a holder of such Registrable Securities.  At
     any such time as Common Stock is listed on any national
     securities exchange, the Company will, at its expense,
     obtain promptly and maintain the approval for listing on
     each such exchange, upon official notice of issuance, the
     shares of Common Stock issuable upon exercise of the then
     outstanding Warrants and maintain the listing of such
     shares after their issuance; and the Company will also
     list on such national securities exchange, will register
     under the Exchange Act and will maintain such listing of,
     any Other Securities that at any time are issuable upon
     exercise of the Warrants, if and at the time that any
     securities of the same class shall be listed on such
     national securities exchange by the Company.

               9.  Restrictions on Transfer.  

               9.1.  Restrictive Legends.  Except as otherwise
     permitted by this section 9, each Warrant (including each
     Warrant issued upon the transfer of any Warrant) shall be
     stamped or otherwise imprinted with a legend in
     substantially the following form:

               "THE WARRANT REPRESENTED BY THIS
          CERTIFICATE (AND THE SHARES OF COMMON STOCK OR
          OTHER SECURITIES ISSUABLE UPON EXERCISE OF SUCH
          WARRANT) HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, OR THE
          SECURITIES LAWS OF ANY STATE IN RELIANCE ON
          CERTAIN EXEMPTIONS FROM REGISTRATION
          THEREUNDER.  THE SALE, PLEDGE, HYPOTHECATION OR
          OTHER TRANSFER OF SUCH WARRANT (AND OF SUCH
          SHARES OF COMMON STOCK OR OTHER SECURITIES) IS
          SUBJECT TO COMPLIANCE WITH APPLICABLE
          SECURITIES LAWS AND REGULATIONS AND CERTAIN
          RESTRICTIONS AND CONDITIONS CONTAINED IN A
          CERTAIN SECURITIES PURCHASE AND EXCHANGE
          AGREEMENT AND RELATED AGREEMENTS DATED AS OF
          JANUARY 31, 1996.  THE HOLDER OF THIS
          CERTIFICATE BY ACCEPTANCE HEREOF AGREES TO BE
          BOUND BY SUCH RESTRICTIONS AND CONDITIONS.  A
          COPY OF THE PURCHASE AGREEMENT IS ON FILE WITH
          THE SECRETARY OF THE COMPANY."

     Except as otherwise permitted by this section 9, each
     certificate for Common Stock (or Other Securities) issued
     upon the exercise of any Warrant, and each certificate
     issued upon the transfer of any such Common Stock (or
     Other Securities), shall be stamped or otherwise

          COPY OF THE SECURITIES PURCHASE AND EXCHANGE
          AGREEMENT IS ON FILE WITH THE SECRETARY OF THE
          COMPANY."

               10.  Availability of Information.  The Company
     shall timely file the reports required to be filed by it
     under the Securities Act and the Exchange Act (including
     but not limited to the reports under sections 13 and
     15(d) of the Exchange Act referred to in subparagraph (c)
     of Rule 144 adopted by the Commission under the
     Securities Act) and the rules and regulations adopted by
     the Commission thereunder (or, if the Company is not
     required to file such reports, will, upon the request of
     any holder of Registrable Securities, make publicly
     available other information) and will take such further
     action as any holder of Registrable Securities may
     reasonably request, all to the extent required from time
     to time to enable such holder to sell Registrable
     Securities without registration under the Securities Act
     within the limitation of the exemptions provided by (a)
     Rule 144 under the Securities Act, as such Rule may be
     amended from time to time, or (b) any similar rule or
     regulation hereafter adopted by the Commission.  Upon the
     request of any holder of Registrable Securities, the
     Company will deliver to such holder a written statement
     as to whether it has complied with the requirements of
     this section 10.

               11.  Reservation of Stock, etc.  The Company
     will at all times reserve and keep available, solely for
     issuance and delivery upon exercise of the Warrants, the
     number of shares of Common Stock (or Other Securities)
     from time to time issuable upon exercise of all Warrants
     at the time outstanding.  All shares of Common Stock (or
     Other Securities) issuable upon exercise of any Warrants
     shall be duly authorized and, when issued upon such
     exercise, shall be validly issued and, in the case of
     shares, fully paid and nonassessable with no liability on
     the part of the holders thereof.

               12.  Registration and Transfer of Warrants,
     etc.

               12.1. Warrant Register; Ownership of Warrants. 
     The Company will keep at its principal office a register
     in which the Company will provide for the registration of
     Warrants and the registration of transfers of Warrants. 
     The Company may treat the Person in whose name any
     Warrant is registered on such register as the owner
     thereof for all other purposes, and the Company shall not
     be affected by any notice to the contrary, except that,
     if and when any Warrant is properly assigned in blank,
     the Company may (but shall not be obligated to) treat the
     bearer thereof as the owner of such Warrant for all
     purposes.  Subject to section 9, a Warrant, if properly
     assigned, may be exercised by a new holder without a new
     Warrant first having been issued.

               12.2.  Transfer and Exchange of Warrants.  Upon
     surrender of any Warrant for registration of transfer or
     for exchange to the Company at its principal office, the
     Company at its expense will (subject to compliance with
     section 9, if applicable) execute and deliver in exchange
     therefor a new Warrant or Warrants of like tenor, in the
     name of such holder or as such holder (upon payment by
     such holder of any applicable transfer taxes) may direct,
     calling in the aggregate on the face or faces thereof for
     the number of shares of Common Stock called for on the
     face or faces of the Warrant or Warrants so surrendered. 

               12.3.  Replacement of Warrants.  Upon receipt
     of evidence reasonably satisfactory to the Company of the
     loss, theft, destruction or mutilation of any Warrant
     and, in the case of any such loss, theft or destruction
     of any Warrant, upon delivery of an indemnity bond in
     such reasonable amount as the Company may determine or,
     in the case of any such mutilation, upon the surrender of
     such Warrant for cancellation to the Company at its
     principal office, the Company at its expense will execute
     and deliver, in lieu thereof, a new Warrant of like
     tenor.  

               13.  Registration Rights.  The Purchaser or any
     assignee of this Warrant shall be entitled to all rights
     and benefits regarding the registration of Common Stock
     and Registrable Securities set forth in the Registration
     Rights Agreement.

          making any adjustment for Additional Shares of

                                       Wand II Regular Warrant

                            NESTOR, INC.

                   Common Stock Purchase Warrant

                                            New York, New York
     No. W-V                                  January 31, 1996

               Nestor, Inc. (the "Company"), a Delaware
     corporation, for value received, hereby certifies that
     Wand/Nestor Investments II L.P. ("Wand"), or registered
     assigns, is entitled to purchase from the Company 20,880
     duly authorized, validly issued, fully paid and
     nonassessable shares of Common Stock, par value $.01 per
     share (the "Common Stock"), of the Company at the
     purchase price per share of $1.25 (provided, however, if
     the Company has not on or before July 31, 1996 entered
     into a definitive agreement with a party with which it is
     currently negotiating, such agreement to contemplate an
     ongoing revenue stream to the Company, based on
     commercial exploitation of the Company's technology, and
     to require a payment to the Company upon execution of at
     least $1.25 million, such payment to be not primarily in
     consideration of any requirement that the Company render
     services, then the purchase price shall automatically be
     reduced to $.75), at any time or from time to time prior
     to 5:00 P.M., New York City time, on August 1, 2004 (or
     such later date as may be determined pursuant to section
     19), all subject to the terms, conditions and adjustments
     set forth below in this Warrant.

               This Warrant is being issued by the Company in
     consideration of Wand's performance of its obligations
     pursuant to the Securities Purchase and Exchange
     Agreement dated as of January 31, 1996 by and between the
     Company and Wand (the "Purchase and Exchange Agreement"). 
     Certain capitalized terms used in this Warrant are
     defined in section 14; references to an "Exhibit" are,
     unless otherwise specified, to one of the Exhibits
     attached to this Warrant and references to a "section"
     are, unless otherwise specified, to one of the sections
     of this Warrant.

               1.  Exercise of Warrant.  

               1.1.  Manner of Exercise.  This Warrant may be
     exercised after June 30, 1996 by the holder hereof, in
     whole or in part, during normal business hours on any
     Business Day, by surrender of this Warrant to the Company
     at its principal office, accompanied by a subscription 
     substantially in the form attached to this Warrant (or a
     reasonable facsimile thereof) duly executed by such
     holder and accompanied by payment, in cash, by certified
     or official bank check payable to the order of the
     Company, or in the manner provided in Section 1.5, in the
     amount obtained by multiplying (a) the number of shares
     of Common Stock (without giving effect to any adjustment
     thereof) designated in such subscription by (b) $1.25
     (provided, however, if the Company has not on or before
     July 31, 1996 entered into a definitive agreement with a
     party with which it is currently negotiating, such
     agreement to contemplate an ongoing revenue stream to the
     Company, based on commercial exploitation of the
     Company's technology, and to require a payment to the
     Company upon execution of at least $1.25 million, such
     payment to be not primarily in consideration of any
     requirement that the Company render services, then the
     purchase price shall automatically be reduced to $.75),
     and such holder shall thereupon be entitled to receive
     the number of duly authorized, validly issued, fully paid
     and nonassessable shares of Common Stock (or Other
     Securities) determined as provided in sections 2 through
     4.

               1.2.  When Exercise Effective.  Each exercise
     of this Warrant shall be deemed to have been effected
     immediately prior to the close of business on the
     Business Day on which this Warrant shall have been
     surrendered to the Company as provided in section 1.1,
     and at such time the Person or Persons in whose name or
     names any certificate or certificates for shares of
     Common Stock (or Other Securities) shall be issuable upon
     such exercise as provided in section 1.3 shall be deemed
     to have become the holder or holders of record thereof.

               1.3.  Delivery of Stock Certificates, etc.  As
     soon as practicable after each exercise of this Warrant,
     in whole or in part, and in any event within five
     Business Days thereafter, the Company at its expense
     (including the payment by it of any applicable issue
     taxes) will cause to be issued in the name of and
     delivered to the holder hereof or, subject to section 9,
     as such holder (upon payment by such holder of any
     applicable transfer taxes) may direct,

               (a)  a certificate or certificates for the
          number of duly authorized, validly issued, fully
          paid and nonassessable shares of Common Stock (or
          Other Securities) to which such holder shall be
          entitled upon such exercise plus, in lieu of any
          fractional share to which such holder would
          otherwise be entitled, cash in an amount equal to
          the same fraction of the Market Price per share on
          the Business Day next preceding the date of such
          exercise, and

               (b)  in case such exercise is in part only, a
          new Warrant or Warrants of like tenor, calling in
          the aggregate on the face or faces thereof for the
          number of shares of Common Stock equal (without
          giving effect to any adjustment thereof) to the
          number of such shares called for on the face of this
          Warrant minus the number of such shares designated
          by the holder upon such exercise as provided in
          section 1.1.

               1.4.  Company to Reaffirm Obligations.  The
     Company will, at the time of each exercise of this
     Warrant, upon the request of the holder hereof,
     acknowledge in writing its continuing obligation to
     afford to such holder all rights (including, without
     limitation, any rights to registration, pursuant to the
     Registration Rights Agreement referred to in section 8,
     of the shares of Common Stock or Other Securities issued
     upon such exercise) to which such holder shall continue
     to be entitled after such exercise in accordance with the
     terms of this Warrant, provided that if the holder of
     this Warrant shall fail to make any such request, such
     failure shall not affect the continuing obligation of the
     Company to afford such rights to such holder.

               1.5.  Payment by Application of Shares
     Otherwise Issuable.  Upon any exercise of this Warrant,
     the holder hereof may, at its option, instruct the
     Company, by written notice accompanying the surrender of
     this Warrant at the time of such exercise, to apply to
     the payment required by section 1.1 such number of the
     shares of Common Stock otherwise issuable to such holder
     upon such exercise as shall be specified in such notice,
     in which case an amount equal to the excess of the
     aggregate Current Market Price of such specified number
     of shares on the date of exercise over the portion of the
     payment required by section 1.1 attributable to such
     shares shall be deemed to have been paid to the Company
     and the number of shares issuable upon such exercise
     shall be reduced by such specified number.

               2.  Adjustment of Common Stock Issuable Upon
     Exercise.  

               2.1.  General; Warrant Price.  The number of
     shares of Common Stock which the holder of this Warrant
     shall be entitled to receive upon each exercise hereof
     shall be determined by multiplying the number of shares
     of Common Stock which would otherwise (but for the
     provisions of this section 2) be issuable upon such
     exercise, as designated by the holder hereof pursuant to
     section 1.1, by the fraction of which (a) the numerator
     is the price then applicable pursuant to section 1.1(b)
     of this Warrant and (b) the denominator is the Warrant
     Price in effect on the date of such exercise.  The
     "Warrant Price" shall initially be $1.25 per share,
     provided, however, if the Company has not on or before
     July 31, 1996 entered into a definitive agreement with a
     party with which it is currently negotiating, such
     agreement to contemplate an ongoing revenue stream to the
     Company, based on commercial exploitation of the
     Company's technology, and to require a payment to the
     Company upon execution of at least $1.25 million, such
     payment to be not primarily in consideration of any
     requirement that the Company render services, then the
     Warrant Price shall automatically be reduced to $.75. 
     The Warrant Price shall be adjusted and readjusted from
     time to time as further provided in this section 2 and,
     as so adjusted or readjusted, shall remain in effect
     until a further adjustment or readjustment thereof is
     required by this section 2.

               2.2.  Adjustment of Warrant Price.

               2.2.1  Issuance of Additional Shares of Common
     Stock.  In case the Company at any time or from time to
     time after the date hereof shall issue or sell Additional
     Shares of Common Stock (including Additional Shares of
     Common Stock deemed to be issued pursuant to section 2.3
     or 2.4) without consideration or for a consideration per
     share less than the Warrant Price in effect immediately
     prior to such issue or sale, then, and in each such case,
     subject to section 2.8, such Warrant Price shall be
     reduced, concurrently with such issue or sale, to a price
     (calculated to the nearest .001 of a cent) equal to the
     consideration per share paid for such Additional Shares
     of Common Stock.

               2.2.2  Extraordinary Dividends and
     Distributions.  In case the Company at any time or from
     time to time after the date hereof shall declare, order,
     pay or make a dividend or other distribution (including,
     without limitation, any distribution of other or
     additional stock or other securities or property or
     Options by way of dividend or spin-off, reclassification,
     recapitalization or similar corporate rearrangement) on
     the Common Stock, other than a dividend payable in (a)
     Additional Shares of Common Stock or (b) cash dividends
     during any fiscal year of the Company that do not exceed
     twenty percent (20%) of the after tax earnings per share
     of the Common Stock for the immediately preceding fiscal
     year of the Company, then, and in each such case, subject
     to section 2.8, the Warrant Price in effect immediately
     prior to the close of business on the record date fixed
     for the determination of holders of any class of
     securities entitled to receive such dividend or
     distribution shall be reduced, effective as of the close
     of business on such record date, to a price (calculated
     to the nearest .001 of a cent) determined by multiplying
     such Warrant Price by a fraction

               (x)  the numerator of which shall be the
          Current Market Price in effect on such record date
          or, if the Common Stock trades on an ex-dividend
          basis, on the date prior to the commencement of ex-
          dividend trading, less the amount of such dividend
          or distribution (as determined in good faith by the
          Board of Directors of the Company, subject to 
          confirmation by a firm of independent certified
          public accountants of recognized national standing
          approved by Wand/Nestor Investments L.P.) applicable
          to one share of Common Stock, and

               (y)  the denominator of which shall be such
          Current Market Price.

               2.3.  Treatment of Options and Convertible
     Securities.  In case the Company at any time or from time
     to time after the date hereof shall issue, sell, grant or
     assume, or shall fix a record date for the determination
     of holders of any class of securities entitled to
     receive, any Options or Convertible Securities, then, and
     in each such case, the maximum number of Additional
     Shares of Common Stock (as set forth in the instrument
     relating thereto, without regard to any provisions
     contained therein for a subsequent adjustment of such
     number) issuable upon the exercise of such Options or, in
     the case of Convertible Securities and Options therefor,
     the conversion or exchange of such Convertible
     Securities, shall be deemed to be Additional Shares of
     Common Stock issued as of the time of such issue, sale,
     grant or assumption or, in case such a record date shall
     have been fixed, as of the close of business on such
     record date (or, if the Common Stock trades on an ex-
     dividend basis, on the date prior to the commencement of
     ex-dividend trading), provided that such Additional
     Shares of Common Stock shall not be deemed to have been
     issued unless the consideration per share (determined
     pursuant to section 2.5) of such shares would be less
     than the Warrant Price in effect on the date of and
     immediately prior to such issue, sale, grant or
     assumption or immediately prior to the close of business
     on such record date (or, if the Common Stock trades on an
     ex-dividend basis, on the date prior to the commencement
     of ex-dividend trading), as the case may be, and
     provided, further, that in any such case in which
     Additional Shares of Common Stock are deemed to be issued

               (a)  no further adjustment of the Warrant Price
          shall be made upon the subsequent issue or sale of
          Convertible Securities or shares of Common Stock
          upon the exercise of such Options or the conversion
          or exchange of such Convertible Securities;

               (b)  if such Options or Convertible Securities
          by their terms provide, with the passage of time or
          otherwise, for any increase in the consideration
          payable to the Company, or decrease in the number of
          Additional Shares of Common Stock issuable, upon the
          exercise, conversion or exchange thereof (by change
          of rate or otherwise), the Warrant Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon any such increase or decrease becoming
          effective, be recomputed to reflect such increase or
          decrease insofar as it affects such Options, or the
          rights of conversion or exchange under such
          Convertible Securities, which are outstanding at
          such time;

               (c)  upon the expiration (or purchase by the
          Company and cancellation or retirement) of any such
          Options which shall not have been exercised or the
          expiration of any rights of conversion or exchange
          under any such Convertible Securities which (or
          purchase by the Company and cancellation or
          retirement of any such Convertible Securities the
          rights of conversion or exchange under which) shall
          not have been exercised, the Warrant Price computed
          upon the original issue, sale, grant or assumption
          thereof (or upon the occurrence of the record date,
          or date prior to the commencement of ex-dividend
          trading, as the case may be, with respect thereto),
          and any subsequent adjustments based thereon, shall,
          upon such expiration (or such cancellation or
          retirement, as the case may be), be recomputed as
          if:


                    (i)  in the case of Options for Common
               Stock or Convertible Securities, the only
               Additional Shares of Common Stock issued or
               sold were the Additional Shares of Common
               Stock, if any, actually issued or sold upon the
               exercise of such Options or the conversion or
               exchange of such Convertible Securities and the
               consideration received therefor was the
               consideration actually received by the Company
               for the issue, sale, grant or assumption of all
               such Options, whether or not exercised, plus
               the consideration actually received by the
               Company upon such exercise, or for the issue or
               sale of all such Convertible Securities which
               were actually converted or exchanged, plus the
               additional consideration, if any, actually
               received by the Company upon such conversion or
               exchange, and

                    (ii) in the case of Options for
               Convertible Securities, only the Convertible
               Securities, if any, actually issued or sold
               upon the exercise of such Options were issued
               at the time of the issue, sale, grant or
               assumption of such Options, and the
               consideration received by the Company for the
               Additional Shares of Common Stock deemed to
               have then been issued was the consideration
               actually received by the Company for the issue,
               sale, grant or assumption of all such Options,
               whether or not exercised, plus the
               consideration deemed to have been received by
               the Company (pursuant to section 2.5) upon the
               issue or sale of such Convertible Securities
               with respect to which such Options were
               actually exercised;

               (d)  no readjustment pursuant to subdivision
          (b) or (c) above shall have the effect of increasing
          the Warrant Price by an amount in excess of the
          amount of the adjustment thereof originally made in
          respect of the issue, sale, grant or assumption of
          such Options or Convertible Securities; and 

               (e)  in the case of any such Options which
          expire by their terms not more than 30 days after
          the date of issue, sale, grant or assumption
          thereof, no adjustment of the Warrant Price shall be
          made until the expiration or exercise of all such
          Options, whereupon such adjustment shall be made in
          the manner provided in subdivision (c) above.

               2.4.  Treatment of Stock Dividends, Stock
     Splits, etc.  In case the Company at any time or from
     time to time after the date hereof shall declare or pay
     any dividend on the Common Stock payable in Common Stock,
     or shall effect a subdivision of the outstanding shares
     of Common Stock into a greater number of shares of Common
     Stock (by reclassification or otherwise than by payment
     of a dividend in Common Stock), then, and in each such
     case, Additional Shares of Common Stock shall be deemed
     to have been issued (a) in the case of any such dividend,
     immediately after the close of business on the record
     date for the determination of holders of any class of
     securities entitled to receive such dividend, or (b) in
     the case of any such subdivision, at the close of
     business on the day immediately prior to the day upon
     which such corporate action becomes effective.

               2.5.  Computation of Consideration.  For the
     purposes of this section 2,

               (a)  the consideration for the issue or sale of
          any Additional Shares of Common Stock shall,
          irrespective of the accounting treatment of such
          consideration,

                    (i)  insofar as it consists of cash, be
               computed at the net amount of cash received by
               the Company, without deducting any expenses
               paid or incurred by the Company or any
               commissions or compensation paid or concessions
               or discounts allowed to underwriters, dealers
               or others performing similar services in
               connection with such issue or sale,

                    (ii)  insofar as it consists of property
               (including securities) other than cash, be
               computed at the fair value thereof at the time
               of such issue or sale, as determined in good
               faith by the Board of Directors of the Company
               (subject to  confirmation by a firm of
               independent certified public accountants of
               recognized  standing approved by Wand/Nestor
               Investments L.P.), and 

                    (iii)  in case Additional Shares of Common
               Stock are issued or sold together with other
               stock or securities or other assets of the
               Company for a consideration which covers both,
               be the portion of such consideration so
               received, computed as provided in clauses (i)
               and (ii) above, allocable to such Additional
               Shares of Common Stock, all as determined in
               good faith by the Board of Directors of the
               Company (subject to  confirmation by a firm of
               independent certified public accountants of
               recognized  standing approved by Wand/Nestor
               Investments L.P.);

               (b)  Additional Shares of Common Stock deemed
          to have been issued pursuant to section 2.3,
          relating to Options and Convertible Securities,
          shall be deemed to have been issued for a
          consideration per share determined by dividing

                    (i)  the total amount, if any, received
               and receivable by the Company as consideration
               for the issue, sale, grant or assumption of the
               Options or Convertible Securities in question,
               plus the minimum aggregate amount of additional
               consideration (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such consideration to protect
               against dilution) payable to the Company upon
               the exercise in full of such Options or the
               conversion or exchange of such Convertible
               Securities or, in the case of Options for
               Convertible Securities, the exercise of such
               Options for Convertible Securities and the
               conversion or exchange of such Convertible
               Securities, in each case computing such
               consideration as provided in the foregoing
               subdivision (a),

     by

                    (ii)  the maximum number of shares of
               Common Stock (as set forth in the instruments
               relating thereto, without regard to any
               provision contained therein for a subsequent
               adjustment of such number to protect against
               dilution) issuable upon the exercise of such
               Options or the conversion or exchange of such
               Convertible Securities; and

               (c)  Additional Shares of Common Stock deemed
          to have been issued pursuant to section 2.4,
          relating to stock dividends, stock splits, etc.,
          shall be deemed to have been issued for no
          consideration.

               2.6.  Adjustments for Combinations, etc.  In
     case the outstanding shares of Common Stock shall be
     combined or consolidated, by reclassification or
     otherwise, into a lesser number of shares of Common
     Stock, the Warrant Price in effect immediately prior to
     such combination or consolidation shall, concurrently
     with the effectiveness of such combination or
     consolidation, be proportionately increased.

               2.7.  Dilution in Case of Other Securities.  In
     case any Other Securities shall be issued or sold or
     shall become subject to issue or sale upon the conversion
     or exchange of any stock (or Other Securities) of the
     Company (or any issuer of Other Securities or any other
     Person referred to in section 3) or to subscription,
     purchase or other acquisition pursuant to any Options
     issued or granted by the Company (or any such other
     issuer or Person) for a consideration such as to dilute,
     on a basis consistent with the standards established in
     the other provisions of this section 2, the purchase
     rights granted by this Warrant, then, and in each such
     case, the computations, adjustments and readjustments
     provided for in this section 2 with respect to the
     Warrant Price shall be made as nearly as possible in the
     manner so provided and applied to determine the amount of
     Other Securities from time to time receivable upon the
     exercise of the Warrants, so as to protect the holders of
     the Warrants against the effect of such dilution.

               2.8.  Minimum Adjustment of Warrant Price.  If
     the amount of any adjustment of the Warrant Price
     required pursuant to this section 2 would be less than
     one percent (1%) of the Warrant Price in effect at the
     time such adjustment is otherwise so required to be made,
     such amount shall be carried forward and adjustment with
     respect thereto made at the time of and together with any
     subsequent adjustment which, together with such amount
     and any other amount or amounts so carried forward, shall
     aggregate at least one percent (1%) of such Warrant
     Price.

               3.  Consolidation, Merger, etc.  

               3.1.   Adjustments for Consolidation, Merger,
     Sale of Assets, Reorganization, etc.  In case the Company
     after the date hereof (a) shall consolidate with or merge
     into any other Person and shall not be the continuing or
     surviving corporation of such consolidation or merger, or
     (b) shall permit any other Person to consolidate with or
     merge into the Company and the Company shall be the
     continuing or surviving Person but, in connection with
     such consolidation or merger, the Common Stock or Other
     Securities shall be changed into or exchanged for stock
     or other securities of any other Person or cash or any
     other property, or (c) shall transfer all or
     substantially all of its properties or assets to any
     other Person, or (d) shall effect a capital
     reorganization or reclassification of the Common Stock or
     Other Securities (other than a capital reorganization or
     reclassification resulting in the issue of Additional
     Shares of Common Stock for which adjustment in the
     Warrant Price is provided in section 2.2.1 or 2.2.2),
     then, and in the case of each such transaction, proper
     provision shall be made so that, upon the basis and the
     terms and in the manner provided in this Warrant, the
     holder of this Warrant, upon the exercise hereof at any
     time after the consummation of such transaction, shall be
     entitled to receive (at the aggregate Warrant Price in
     effect at the time of such consummation for all Common
     Stock or Other Securities issuable upon such exercise
     immediately prior to such consummation), in lieu of the
     Common Stock or Other Securities issuable upon such
     exercise prior to such consummation, the highest amount
     of securities, cash or other property to which such
     holder would actually have been entitled as a shareholder
     upon such consummation if such holder had exercised the
     rights represented by this Warrant immediately prior
     thereto, subject to adjustments (subsequent to such
     consummation) as nearly equivalent as possible to the
     adjustments provided for in sections 2 through 4.

               3.2.  Assumption of Obligations. 
     Notwithstanding anything contained in the Warrants or in
     the Purchase Agreement to the contrary, the Company will
     not effect any of the transactions described in clauses
     (a) through (d) of section 3.1 unless, prior to the
     consummation thereof, each Person (other than the
     Company) which may be required to deliver any stock,
     securities, cash or property upon the exercise of this
     Warrant as provided herein shall assume, by written
     instrument delivered to, and reasonably satisfactory to,
     the holder of this Warrant, (a) the obligations of the
     Company under this Warrant (and if the Company shall
     survive the consummation of such transaction, such
     assumption shall be in addition to, and shall not release
     the Company from, any continuing obligations of the
     Company under this Warrant), (b) the obligations of the
     Company under the Registration Rights Agreement and (c)
     the obligation to deliver to such holder such shares of
     stock, securities, cash or property as, in accordance
     with the foregoing provisions of this section 3, such
     holder may be entitled to receive, and such Person shall
     have similarly delivered to such holder an opinion of
     counsel for such Person, which counsel shall be
     reasonably satisfactory to such holder, stating that this
     Warrant shall thereafter continue in full force and
     effect and the terms hereof (including, without
     limitation, all of the provisions of this section 3)
     shall be applicable to the stock, securities, cash or
     property which such Person may be required to deliver
     upon any exercise of this Warrant or the exercise of any
     rights pursuant hereto.

               4.  Other Dilutive Events.  In case any event
     shall occur as to which the provisions of section 2 or
     section 3 are not strictly applicable but the failure to
     make any adjustment would not fairly protect the purchase
     rights represented by this Warrant in accordance with the
     essential intent and principles of such sections, then,
     in each such case, the Company shall appoint a firm of
     independent certified public accountants of recognized
     national standing (such firm to be subject to the
     approval of Wand/Nestor Investments L.P.), which shall
     give their opinion regarding the adjustment, if any, on a
     basis consistent with the essential intent and principles
     established in sections 2 and 3, necessary to preserve,
     without dilution, the purchase rights represented by this
     Warrant.  Upon receipt of such opinion, the Company will
     promptly mail a copy thereof to the holder of this
     Warrant and shall make the adjustments described therein.

               5.  No Dilution or Impairment.  The Company
     will not, by amendment of its certificate of
     incorporation or through any consolidation, merger,
     reorganization, transfer of assets, dissolution, issue or
     sale of securities or any other voluntary action, avoid
     or seek to avoid the observance or performance of any of
     the terms of this Warrant, but will at all times in good
     faith assist in the carrying out of all such terms and in
     the taking of all such action as may be necessary or
     appropriate in order to protect the rights of the holder
     of this Warrant against dilution or other impairment. 
     Without limiting the generality of the foregoing, the
     Company (a) will not permit the par value of any shares
     of stock receivable upon the exercise of this Warrant to
     exceed the amount payable therefor upon such exercise,
     (b) will take all such action as may be necessary or
     appropriate in order that the Company may validly and
     legally issue fully paid and nonassessable shares of
     stock on the exercise of the Warrants from time to time
     outstanding, and (c) will not take any action which
     results in any adjustment of the Warrant Price if the
     total number of shares of Common Stock (or Other
     Securities) issuable after the action upon the exercise
     of all of the Warrants would exceed the total number of
     shares of Common Stock (or Other Securities) then
     authorized by the Company's certificate of incorporation
     and available for the purpose of issue upon such
     exercise.

               6.  Accountants' Report as to Adjustments.  In
     each case of any adjustment or readjustment in the shares
     of Common Stock (or Other Securities) issuable upon the
     exercise of this Warrant, the Company at its expense will
     promptly compute such adjustment or readjustment in
     accordance with the terms of this Warrant and cause
     independent certified public accountants of recognized
     standing (such firm to be subject to the approval of
     Wand/Nestor Investments L.P.) selected by the Company to
     verify such computation and prepare a report setting
     forth such adjustment or readjustment and showing in
     reasonable detail the method of calculation thereof and
     the facts upon which such adjustment or readjustment is
     based, including a statement of (a) the consideration
     received or to be received by the Company for any
     Additional Shares of Common Stock issued or sold or
     deemed to have been issued, (b) the number of shares of
     Common Stock outstanding or deemed to be outstanding, and
     (c) the Warrant Price in effect immediately prior to such
     issue or sale and as adjusted and readjusted (if required
     by section 2) on account thereof.  The Company will
     forthwith mail a copy of each such report to each holder
     of a Warrant and will, upon the written request at any
     time of any holder of a Warrant, furnish to such holder a
     like report setting forth the Warrant Price at the time
     in effect and showing in reasonable detail how it was
     calculated.  The Company will also keep copies of all
     such reports at its principal office and will cause the
     same to be available for inspection at such office during
     normal business hours by any holder of a Warrant or any
     prospective purchaser of a Warrant designated by the
     holder thereof.

               7.  Notices of Corporate Action.  In the event of
               (a)  any taking by the Company of a record of
          the holders of any class of securities for the
          purpose of determining the holders thereof who are
          entitled to receive any dividend (other than a
          regular periodic dividend payable in cash out of
          earned surplus in an amount not exceeding the amount
          of the immediately preceding cash dividend for such
          period) or other distribution, or any right to
          subscribe for, purchase or otherwise acquire any
          shares of stock of any class or any other securities
          or property, or to receive any other right, or 

               (b)  any capital reorganization of the Company,
          any reclassification or recapitalization of the
          capital stock of the Company or any consolidation or
          merger involving the Company and any other Person or
          any transfer of all or substantially all the assets
          of the Company to any other Person, or

               (c)  any voluntary or involuntary dissolution,
          liquidation or winding-up of the Company,

     the Company will mail to each holder of a Warrant a
     notice specifying (i) the date or expected date on which
     any such record is to be taken for the purpose of such
     dividend, distribution or right, and the amount and
     character of such dividend, distribution or right, and
     (ii) the date or expected date on which any such
     reorganization, reclassification, recapitalization,
     consolidation, merger, transfer, dissolution, liquidation
     or winding-up is to take place and the time, if any such
     time is to be fixed, as of which the holders of record of
     Common Stock (or Other Securities) shall be entitled to
     exchange their shares of Common Stock (or Other
     Securities) for the securities or other property
     deliverable upon such reorganization, reclassification,
     recapitalization, consolidation, merger, transfer,
     dissolution, liquidation or winding-up.  Such notice
     shall be mailed at least 45 days prior to the date
     therein specified.

               8.  Registration of Common Stock.  If any
     shares of Common Stock required to be reserved for
     purposes of exercise of this Warrant require registration
     with or approval of any governmental authority under any
     federal or state law (other than the Securities Act)
     before such shares may be issued upon exercise, the
     Company will, at its expense and as expeditiously as
     possible, use its best efforts to cause such shares to be
     duly registered or approved, as the case may be.  The
     shares of Common Stock (and Other Securities) issuable
     upon exercise of this Warrant (or upon conversion of any
     shares of Common Stock issued upon such exercise) shall
     constitute Registrable Securities (as such term is
     defined in the Registration Rights Agreement).  Each
     holder of this Warrant shall be entitled to all of the
     benefits afforded to a holder of any such Registrable
     Securities under the Registration Rights Agreement and
     such holder, by its acceptance of this Warrant, agrees to
     be bound by and to comply with the terms and conditions
     of the Registration Rights Agreement applicable to such
     holder as a holder of such Registrable Securities.  At
     any such time as Common Stock is listed on any national
     securities exchange, the Company will, at its expense,
     obtain promptly and maintain the approval for listing on
     each such exchange, upon official notice of issuance, the
     shares of Common Stock issuable upon exercise of the then
     outstanding Warrants and maintain the listing of such
     shares after their issuance; and the Company will also
     list on such national securities exchange, will register
     under the Exchange Act and will maintain such listing of,
     any Other Securities that at any time are issuable upon
     exercise of the Warrants, if and at the time that any
     securities of the same class shall be listed on such
     national securities exchange by the Company.

               9.  Restrictions on Transfer.  

               9.1.  Restrictive Legends.  Except as otherwise
     permitted by this section 9, each Warrant (including each
     Warrant issued upon the transfer of any Warrant) shall be
     stamped or otherwise imprinted with a legend in
     substantially the following form:

               "THE WARRANT REPRESENTED BY THIS
          CERTIFICATE (AND THE SHARES OF COMMON STOCK OR
          OTHER SECURITIES ISSUABLE UPON EXERCISE OF SUCH
          WARRANT) HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, OR THE
          SECURITIES LAWS OF ANY STATE IN RELIANCE ON
          CERTAIN EXEMPTIONS FROM REGISTRATION
          THEREUNDER.  THE SALE, PLEDGE, HYPOTHECATION OR
          OTHER TRANSFER OF SUCH WARRANT (AND OF SUCH
          SHARES OF COMMON STOCK OR OTHER SECURITIES) IS
          SUBJECT TO COMPLIANCE WITH APPLICABLE
          SECURITIES LAWS AND REGULATIONS AND CERTAIN
          RESTRICTIONS AND CONDITIONS CONTAINED IN A
          CERTAIN SECURITIES PURCHASE AND EXCHANGE
          AGREEMENT AND RELATED AGREEMENTS DATED AS OF
          JANUARY 31, 1996.  THE HOLDER OF THIS
          CERTIFICATE BY ACCEPTANCE HEREOF AGREES TO BE
          BOUND BY SUCH RESTRICTIONS AND CONDITIONS.  A
          COPY OF THE PURCHASE AGREEMENT IS ON FILE WITH
          THE SECRETARY OF THE COMPANY."

     Except as otherwise permitted by this section 9, each
     certificate for Common Stock (or Other Securities) issued
     upon the exercise of any Warrant, and each certificate
     issued upon the transfer of any such Common Stock (or
     Other Securities), shall be stamped or otherwise
     imprinted with a legend in substantially the following
     form:

               "THE SHARES OF STOCK REPRESENTED BY THIS
          CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, OR THE
          SECURITIES LAWS OF ANY STATE IN RELIANCE ON
          CERTAIN EXEMPTIONS FROM REGISTRATION
          THEREUNDER.  THE SALE, PLEDGE, HYPOTHECATION OR
          OTHER TRANSFER OF SUCH SHARES IS SUBJECT TO
          COMPLIANCE WITH APPLICABLE SECURITIES LAWS AND
          REGULATIONS AND CERTAIN RESTRICTIONS AND
          CONDITIONS CONTAINED IN A CERTAIN SECURITIES
          PURCHASE AND EXCHANGE AGREEMENT DATED AS OF
          JANUARY 31, 1996.  THE HOLDER OF THIS
          CERTIFICATE BY ACCEPTANCE HEREOF AGREES TO BE
          BOUND BY SUCH RESTRICTIONS AND CONDITIONS.  A
          COPY OF THE SECURITIES PURCHASE AND EXCHANGE
          AGREEMENT IS ON FILE WITH THE SECRETARY OF THE
          COMPANY."

               10.  Availability of Information.  The Company
     shall timely file the reports required to be filed by it
     under the Securities Act and the Exchange Act (including
     but not limited to the reports under sections 13 and
     15(d) of the Exchange Act referred to in subparagraph (c)
     of Rule 144 adopted by the Commission under the
     Securities Act) and the rules and regulations adopted by
     the Commission thereunder (or, if the Company is not
     required to file such reports, will, upon the request of
     any holder of Registrable Securities, make publicly
     available other information) and will take such further
     action as any holder of Registrable Securities may
     reasonably request, all to the extent required from time
     to time to enable such holder to sell Registrable
     Securities without registration under the Securities Act
     within the limitation of the exemptions provided by (a)
     Rule 144 under the Securities Act, as such Rule may be
     amended from time to time, or (b) any similar rule or
     regulation hereafter adopted by the Commission.  Upon the
     request of any holder of Registrable Securities, the
     Company will deliver to such holder a written statement
     as to whether it has complied with the requirements of
     this section 10.

               11.  Reservation of Stock, etc.  The Company
     will at all times reserve and keep available, solely for
     issuance and delivery upon exercise of the Warrants, the
     number of shares of Common Stock (or Other Securities)
     from time to time issuable upon exercise of all Warrants
     at the time outstanding.  All shares of Common Stock (or
     Other Securities) issuable upon exercise of any Warrants
     shall be duly authorized and, when issued upon such
     exercise, shall be validly issued and, in the case of
     shares, fully paid and nonassessable with no liability on
     the part of the holders thereof.

               12.  Registration and Transfer of Warrants,
     etc.

               12.1. Warrant Register; Ownership of Warrants. 
     The Company will keep at its principal office a register
     in which the Company will provide for the registration of
     Warrants and the registration of transfers of Warrants. 
     The Company may treat the Person in whose name any
     Warrant is registered on such register as the owner
     thereof for all other purposes, and the Company shall not
     be affected by any notice to the contrary, except that,
     if and when any Warrant is properly assigned in blank,
     the Company may (but shall not be obligated to) treat the
     bearer thereof as the owner of such Warrant for all

     such reasonable amount as the Company may determine or,
     in the case of any such mutilation, upon the surrender of
     such Warrant for cancellation to the Company at its
     principal office, the Company at its expense will execute
     and deliver, in lieu thereof, a new Warrant of like
     tenor.

          assigns, is entitled to purchase from the Company 416,115
          duly authorized, validly issued, fully paid and
          nonassessable shares of Common Stock par value $.01 per
          share (the "Common Stock"), of the Company at the

          pursuant to section 19), all subject to the terms,
          conditions and adjustments set forth below in this
          Warrant.

                    This Warrant is issued in exchange for a
          warrant issued on October 5, 1995 pursuant to the First
          Amended and Restated Standby Financing and Purchase
          Agreement, dated as of June 30, 1995 (the "Revised
          Standby Agreement"), by and between the Company and
          Wand/Nestor Investments L.P., a Delaware limited
          partnership ("Wand I") in exchange for the Common Stock
          Purchase Warrants originally issued in connection with
          the issue and private sale by the Company of Series C
          Preferred Stock, pursuant to the Securities Purchase
          Agreement (the "Purchase Agreement"), dated as of August
          1, 1994, between the Company and Wand I. This Warrant is
          being issued in connection with the exchange of the
          outstanding Series C Preferred Stock for Series E
          Convertible Preferred Stock (the "Series E Preferred
          Stock") and Series H Convertible Preferred Stock (the
          "Series H Preferred Stock") of the Company pursuant to
          the Securities Purchase and Exchange Agreement, dated as
          of January 31, 1996, among the Company, Wand and certain
          affiliates of Wand.  Certain capitalized terms used in

          "section" are, unless otherwise specified, to one of the
          sections of this Warrant.

                    1.  Exercise of Warrant.  1.1.  Manner of
          Exercise.  Subject to the instructions set forth in
          Section 1.6, this Warrant may be exercised by the holder
          hereof, in whole or in part, during normal business hours
          on any Business Day, by surrender of this Warrant to the
          Company at its principal office, accompanied by a
          subscription   substantially in the form attached to this
          Warrant (or a reasonable facsimile thereof) duly executed
          by such holder and accompanied by payment, in cash, by
          certified or official bank check payable to the order of
          the Company, or in the manner provided in Section 1.5, in
          the amount obtained by multiplying (a) the number of
          shares of Common Stock (without giving effect to any
          adjustment thereof) designated in such subscription by
          (b) $.65, and such holder shall thereupon be entitled to
          receive the number of duly authorized, validly issued,
          fully paid and nonassessable shares of Common Stock (or
          Other Securities) determined as provided in sections 2
          through 4.

                    1.2.  When Exercise Effective.  Each exercise
          of this Warrant shall be deemed to have been effected
          immediately prior to the close of business on the
          Business Day on which this Warrant shall have been
          surrendered to the Company as provided in section 1.1,
          and at such time the Person or Persons in whose name or
          names any certificate or certificates for shares of
          Common Stock (or Other Securities) shall be issuable upon
          such exercise as provided in section 1.3 shall be deemed
          to have become the holder or holders of record thereof.

                    1.3.  Delivery of Stock Certificates, etc.  As
          soon as practicable after each exercise of this Warrant,
          in whole or in part, and in any event within five
          Business Days thereafter, the Company at its expense
          (including the payment by it of any applicable issue
          taxes) will cause to be issued in the name of and
          delivered to the holder hereof or, subject to section 9,
          as such holder (upon payment by such holder of any
          applicable transfer taxes) may direct,

                    (a)  a certificate or certificates for the
               number of duly authorized, validly issued, fully
               paid and nonassessable shares of Common Stock (or
               Other Securities) to which such holder shall be
               entitled upon such exercise plus, in lieu of any
               fractional share to which such holder would
               otherwise be entitled, cash in an amount equal to
               the same fraction of the Market Price per share on
               the Business Day next preceding the date of such
               exercise, and

                    (b)  in case such exercise is in part only, a
               new Warrant or Warrants of like tenor, calling in
               the aggregate on the face or faces thereof for the
               number of shares of Common Stock equal (without
               giving effect to any adjustment thereof) to the
               number of such shares called for on the face of this
               Warrant minus the number of such shares designated
               by the holder upon such exercise as provided in
               section 1.1.

                    1.4.  Company to Reaffirm Obligations.  The
          Company will, at the time of each exercise of this
          Warrant, upon the request of the holder hereof,
          acknowledge in writing its continuing obligation to
          afford to such holder all rights (including, without
          limitation, any rights to registration, pursuant to the
          Registration Rights Agreement referred to in section 8,
          of the shares of Common Stock or Other Securities issued
          upon such exercise) to which such holder shall continue
          to be entitled after such exercise in accordance with the
          terms of this Warrant, provided that if the holder of
          this Warrant shall fail to make any such request, such
          failure shall not affect the continuing obligation of the
          Company to afford such rights to such holder.

                    1.5.  Payment by Application of Shares
          Otherwise Issuable.  Upon any exercise of this Warrant,
          the holder hereof may, at its option, instruct the
          Company, by written notice accompanying the surrender of
          this Warrant at the time of such exercise, to apply to
          the payment required by section 1.1 such number of the
          shares of Common Stock otherwise issuable to such holder
          upon such exercise as shall be specified in such notice,
          in which case an amount equal to the excess of the
          aggregate Current Market Price of such specified number
          of shares on the date of exercise over the portion of the
          payment required by section 1.1 attributable to such
          shares shall be deemed to have been paid to the Company
          and the number of shares issuable upon such exercise
          shall be reduced by such specified number.

                    1.6.  Restrictions Upon Exercise by BHCA
          Holder.  A BHCA Holder may only exercise this Warrant, in
          whole or in part, in connection with the sale of the
          Common Stock issuable upon the exercise of the Warrant to
          an unaffiliated third party (a) in a widely dispersed
          public offering, (b) to one or more investors, in one or
          more transactions, none of whom, after such purchase
          would hold more than 2% of the voting securities of the
          Company then outstanding, (c) to any Person that already
          controls the Company prior to such transfer, (d) in a
          transaction that complies with Rule 144 (or any successor
          thereto) of the Securities Act of 1933, as amended, or
          (e) in any other transaction approved in advance by the
          Federal Reserve System.

                    2.  Adjustment of Common Stock Issuable Upon
          Exercise.  2.1.  General; Warrant Price.  The number of
          shares of Common Stock which the holder of this Warrant
          shall be entitled to receive upon each exercise hereof
          shall be determined by multiplying the number of shares
          of Common Stock which would otherwise (but for the
          provisions of this section 2) be issuable upon such
          exercise, as designated by the holder hereof pursuant to
          section 1.1, by the fraction of which (a) the numerator
          is $.65 and (b) the denominator is the Warrant Price in
          effect on the date of such exercise.  The "Warrant Price"
          shall initially be $.65 per share, shall be adjusted and
          readjusted from time to time as provided in this section
          2 and, as so adjusted or readjusted, shall remain in
          effect until a further adjustment or readjustment thereof
          is required by this section 2.  In addition to the other
          adjustments herein provided, the "Warrant Price" shall be
          subject to the following special adjustments:

                    (i)  If the Series E Preferred Stock and Series
                         H Preferred are redeemed by the Company on
                         or prior to August 1, 2000 then the
                         "Warrant Price" shall

                         (A)  be reduced by 25%, after all other
                              adjustments required by this section
                              2 have been made, if the redemption
                              occurs prior to August 1, 1996;


                         (B)  be reduced by 20%, after all other
                              adjustments required by this section
                              2 have been made, if the redemption
                              occurs on or after August 1, 1996 and
                              prior to August 1, 1997;

                         (C)  be reduced by 15%, after all other
                              adjustments required by this section
                              2 have been made, if the redemption
                              occurs on or after August 1, 1997 and
                              prior to August 1, 1998;

                         (D)  be reduced by 10%, after all other
                              adjustments required by this section
                              2 have been made, if the redemption
                              occurs on or after August 1, 1998 and
                              prior to August 1, 1999; and

                         (E)  be reduced by 5%, after all other
                              adjustments required by this section
                              2 have been made, if the redemption
                              occurs on or after August 1, 1999 and
                              prior to August 1, 2000.

                    2.2.  Adjustment of Warrant Price.

                    2.2.1  Issuance of Additional Shares of Common
          Stock.  In case the Company at any time or from time to
          time after the date hereof shall issue or sell Additional
          Shares of Common Stock (including Additional Shares of
          Common Stock deemed to be issued pursuant to section 2.3
          or 2.4) without consideration or for a consideration per
          share less than the Warrant Price in effect immediately
          prior to such issue or sale, then, and in each such case,
          subject to section 2.8, such Warrant Price shall be
          reduced, concurrently with such issue or sale, to a price
          (calculated to the nearest .001 of a cent) determined by
          multiplying such Warrant Price by a fraction

                    (a)  the numerator of which shall be (i) the
               number of shares of Common Stock outstanding
               immediately prior to such issue or sale plus (ii)
               the number of shares of Common Stock which the
               aggregate consideration received by the Company for
               the total number of such Additional Shares of Common
               Stock so issued or sold would purchase at such
               Warrant Price, and

                    (b)  the denominator of which shall be the
               number of shares of Common Stock outstanding
               immediately after such issue or sale,

          provided that, for the purposes of this section 2.2.1,
          (x) immediately after any Additional Shares of Common
          Stock are deemed to have been issued pursuant to section
          2.3 or 2.4, such Additional Shares shall be deemed to be
          outstanding, and (y) treasury shares shall not be deemed
          to be outstanding.

                    2.2.2  Extraordinary Dividends and
          Distributions.  In case the Company at any time or from
          time to time after the date hereof shall declare, order,
          pay or make a dividend or other distribution (including,
          without limitation, any distribution of other or
          additional stock or other securities or property or
          Options by way of dividend or spin-off, reclassification,
          recapitalization or similar corporate rearrangement) on
          the Common Stock, other than (a) a dividend payable in
          Additional Shares of Common Stock or (b) cash dividends
          during any fiscal year of the Company that do not exceed
          twenty percent (20%) of the after tax earnings per share
          of the Common Stock for the immediately preceding fiscal
          year of the Company, then, and in each such case, subject
          to section 2.8, the Warrant Price in effect immediately
          prior to the close of business on the record date fixed
          for the determination of holders of any class of
          securities entitled to receive such dividend or
          distribution shall be reduced, effective as of the close
          of business on such record date, to a price (calculated
          to the nearest .001 of a cent) determined by multiplying
          such Warrant Price by a fraction

                    (x)  the numerator of which shall be the
               Current Market Price in effect on such record date
               or, if the Common Stock trades on an ex-dividend
               basis, on the date prior to the commencement of ex-
               dividend trading, less the amount of such dividend
               or distribution (as determined in good faith by the
               Board of Directors of the Company, subject to 
               confirmation by a firm of independent certified
               public accountants of recognized national standing
               approved by Wand/Nestor Investments L.P.) applicable
               to one share of Common Stock, and

                    (y)  the denominator of which shall be such
               Current Market Price.

                    2.3.  Treatment of Options and Convertible
          Securities.  In case the Company at any time or from time
          to time after the date hereof shall issue, sell, grant or
          assume, or shall fix a record date for the determination
          of holders of any class of securities entitled to
          receive, any Options or Convertible Securities, then, and
          in each such case, the maximum number of Additional
          Shares of Common Stock (as set forth in the instrument
          relating thereto, without regard to any provisions
          contained therein for a subsequent adjustment of such
          number) issuable upon the exercise of such Options or, in
          the case of Convertible Securities and Options therefor,
          the conversion or exchange of such Convertible
          Securities, shall be deemed to be Additional Shares of
          Common Stock issued as of the time of such issue, sale,
          grant or assumption or, in case such a record date shall
          have been fixed, as of the close of business on such
          record date (or, if the Common Stock trades on an ex-
          dividend basis, on the date prior to the commencement of
          ex-dividend trading), provided that such Additional
          Shares of Common Stock shall not be deemed to have been
          issued unless the consideration per share (determined
          pursuant to section 2.5) of such shares would be less
          than the Warrant Price in effect on the date of and
          immediately prior to such issue, sale, grant or
          assumption or immediately prior to the close of business
          on such record date (or, if the Common Stock trades on an
          ex-dividend basis, on the date prior to the commencement
          of ex-dividend trading), as the case may be, and
          provided, further, that in any such case in which
          Additional Shares of Common Stock are deemed to be issued

                    (a)  no further adjustment of the Warrant Price
               shall be made upon the subsequent issue or sale of
               Convertible Securities or shares of Common Stock
               upon the exercise of such Options or the conversion
               or exchange of such Convertible Securities;

                    (b)  if such Options or Convertible Securities
               by their terms provide, with the passage of time or
               otherwise, for any increase in the consideration
               payable to the Company, or decrease in the number of
               Additional Shares of Common Stock issuable, upon the
               exercise, conversion or exchange thereof (by change
               of rate or otherwise), the Warrant Price computed
               upon the original issue, sale, grant or assumption
               thereof (or upon the occurrence of the record date,
               or date prior to the commencement of ex-dividend
               trading, as the case may be, with respect thereto),
               and any subsequent adjustments based thereon, shall,
               upon any such increase or decrease becoming
               effective, be recomputed to reflect such increase or
               decrease insofar as it affects such Options, or the
               rights of conversion or exchange under such
               Convertible Securities, which are outstanding at
               such time;

                    (c)  upon the expiration (or purchase by the
               Company and cancellation or retirement) of any such
               Options which shall not have been exercised or the
               expiration of any rights of conversion or exchange
               under any such Convertible Securities which (or
               purchase by the Company and cancellation or
               retirement of any such Convertible Securities the
               rights of conversion or exchange under which) shall
               not have been exercised, the Warrant Price computed
               upon the original issue, sale, grant or assumption
               thereof (or upon the occurrence of the record date,
               or date prior to the commencement of ex-dividend
               trading, as the case may be, with respect thereto),
               and any subsequent adjustments based thereon, shall,
               upon such expiration (or such cancellation or
               retirement, as the case may be), be recomputed as
               if:

                         (i)  in the case of Options for Common
                    Stock or Convertible Securities, the only
                    Additional Shares of Common Stock issued or
                    sold were the Additional Shares of Common
                    Stock, if any, actually issued or sold upon the
                    exercise of such Options or the conversion or
                    exchange of such Convertible Securities and the
                    consideration received therefor was the
                    consideration actually received by the Company
                    for the issue, sale, grant or assumption of all
                    such Options, whether or not exercised, plus
                    the consideration actually received by the
                    Company upon such exercise, or for the issue or
                    sale of all such Convertible Securities which
                    were actually converted or exchanged, plus the
                    additional consideration, if any, actually
                    received by the Company upon such conversion or
                    exchange, and

                         (ii) in the case of Options for
                    Convertible Securities, only the Convertible
                    Securities, if any, actually issued or sold
                    upon the exercise of such Options were issued
                    at the time of the issue, sale, grant or
                    assumption of such Options, and the
                    consideration received by the Company for the
                    Additional Shares of Common Stock deemed to
                    have then been issued was the consideration
                    actually received by the Company for the issue,
                    sale, grant or assumption of all such Options,
                    whether or not exercised, plus the
                    consideration deemed to have been received by
                    the Company (pursuant to section 2.5) upon the
                    issue or sale of such Convertible Securities
                    with respect to which such Options were
                    actually exercised;

                    (d)  no readjustment pursuant to subdivision
               (b) or (c) above shall have the effect of increasing
               the Warrant Price by an amount in excess of the
               amount of the adjustment thereof originally made in
               respect of the issue, sale, grant or assumption of
               such Options or Convertible Securities; and 

                    (e)  in the case of any such Options which
               expire by their terms not more than 30 days after
               the date of issue, sale, grant or assumption
               thereof, no adjustment of the Warrant Price shall be
               made until the expiration or exercise of all such
               Options, whereupon such adjustment shall be made in
               the manner provided in subdivision (c) above.

                    2.4.  Treatment of Stock Dividends, Stock
          Splits, etc.  In case the Company at any time or from
          time to time after the date hereof shall declare or pay
          any dividend on the Common Stock payable in Common Stock,
          or shall effect a subdivision of the outstanding shares
          of Common Stock into a greater number of shares of Common
          Stock (by reclassification or otherwise than by payment
          of a dividend in Common Stock), then, and in each such
          case, Additional Shares of Common Stock shall be deemed
          to have been issued (a) in the case of any such dividend,
          immediately after the close of business on the record
          date for the determination of holders of any class of
          securities entitled to receive such dividend, or (b) in
          the case of any such subdivision, at the close of
          business on the day immediately prior to the day upon
          which such corporate action becomes effective.

                    2.5.  Computation of Consideration.  For the
          purposes of this section 2,

                    (a)  the consideration for the issue or sale of
               any Additional Shares of Common Stock shall,
               irrespective of the accounting treatment of such
               consideration,

                         (i)  insofar as it consists of cash, be
                    computed at the net amount of cash received by
                    the Company, without deducting any expenses
                    paid or incurred by the Company or any
                    commissions or compensation paid or concessions
                    or discounts allowed to underwriters, dealers
                    or others performing similar services in
                    connection with such issue or sale,

                         (ii)  insofar as it consists of property
                    (including securities) other than cash, be
                    computed at the fair value thereof at the time
                    of such issue or sale, as determined in good
                    faith by the Board of Directors of the Company
                    (subject to  confirmation by a firm of
                    independent certified public accountants of
                    recognized  standing approved by Wand/Nestor
                    Investments L.P.), and 

                         (iii)  in case Additional Shares of Common
                    Stock are issued or sold together with other
                    stock or securities or other assets of the
                    Company for a consideration which covers both,
                    be the portion of such consideration so
                    received, computed as provided in clauses (i)
                    and (ii) above, allocable to such Additional
                    Shares of Common Stock, all as determined in
                    good faith by the Board of Directors of the
                    Company (subject to  confirmation by a firm of
                    independent certified public accountants of
                    recognized  standing approved by Wand/Nestor
                    Investments L.P.);

                    (b)  Additional Shares of Common Stock deemed
               to have been issued pursuant to section 2.3,
               relating to Options and Convertible Securities,
               shall be deemed to have been issued for a
               consideration per share determined by dividing

                         (i)  the total amount, if any, received
                    and receivable by the Company as consideration
                    for the issue, sale, grant or assumption of the
                    Options or Convertible Securities in question,
                    plus the minimum aggregate amount of additional
                    consideration (as set forth in the instruments
                    relating thereto, without regard to any
                    provision contained therein for a subsequent
                    adjustment of such consideration to protect
                    against dilution) payable to the Company upon
                    the exercise in full of such Options or the
                    conversion or exchange of such Convertible
                    Securities or, in the case of Options for
                    Convertible Securities, the exercise of such
                    Options for Convertible Securities and the
                    conversion or exchange of such Convertible
                    Securities, in each case computing such
                    consideration as provided in the foregoing
                    subdivision (a),

          by

                         (ii)  the maximum number of shares of
                    Common Stock (as set forth in the instruments
                    relating thereto, without regard to any
                    provision contained therein for a subsequent
                    adjustment of such number to protect against
                    dilution) issuable upon the exercise of such
                    Options or the conversion or exchange of such
                    Convertible Securities; and

                    (c)  Additional Shares of Common Stock deemed
               to have been issued pursuant to section 2.4,
               relating to stock dividends, stock splits, etc.,
               shall be deemed to have been issued for no
               consideration.

                    2.6.  Adjustments for Combinations, etc.  In
          case the outstanding shares of Common Stock shall be
          combined or consolidated, by reclassification or
          otherwise, into a lesser number of shares of Common
          Stock, the Warrant Price in effect immediately prior to
          such combination or consolidation shall, concurrently
          with the effectiveness of such combination or
          consolidation, be proportionately increased.

                    2.7.  Dilution in Case of Other Securities.  In
          case any Other Securities shall be issued or sold or
          shall become subject to issue or sale upon the conversion
          or exchange of any stock (or Other Securities) of the
          Company (or any issuer of Other Securities or any other
          Person referred to in section 3) or to subscription,
          purchase or other acquisition pursuant to any Options
          issued or granted by the Company (or any such other
          issuer or Person) for a consideration such as to dilute,
          on a basis consistent with the standards established in
          the other provisions of this section 2, the purchase
          rights granted by this Warrant, then, and in each such
          case, the computations, adjustments and readjustments
          provided for in this section 2 with respect to the
          Warrant Price shall be made as nearly as possible in the
          manner so provided and applied to determine the amount of
          Other Securities from time to time receivable upon the
          exercise of the Warrants, so as to protect the holders of
          the Warrants against the effect of such dilution.

                    2.8.  Minimum Adjustment of Warrant Price.  If
          the amount of any adjustment of the Warrant Price
          required pursuant to this section 2 would be less than
          one percent (1%) of the Warrant Price in effect at the
          time such adjustment is otherwise so required to be made,
          such amount shall be carried forward and adjustment with
          respect thereto made at the time of and together with any
          subsequent adjustment which, together with such amount
          and any other amount or amounts so carried forward, shall
          aggregate at least one percent (1%) of such Warrant
          Price.

                    3.  Consolidation, Merger, etc.  3.1.  
          Adjustments for Consolidation, Merger, Sale of Assets,
          Reorganization, etc.  In case the Company after the date
          hereof (a) shall consolidate with or merge into any other
          Person and shall not be the continuing or surviving
          corporation of such consolidation or merger, or (b) shall
          permit any other Person to consolidate with or merge into
          the Company and the Company shall be the continuing or
          surviving Person but, in connection with such
          consolidation or merger, the Common Stock or Other
          Securities shall be changed into or exchanged for stock
          or other securities of any other Person or cash or any
          other property, or (c) shall transfer all or
          substantially all of its properties or assets to any
          other Person, or (d) shall effect a capital
          reorganization or reclassification of the Common Stock or
          Other Securities (other than a capital reorganization or
          reclassification resulting in the issue of Additional
          Shares of Common Stock for which adjustment in the
          Warrant Price is provided in section 2.2.1 or 2.2.2),
          then, and in the case of each such transaction, proper
          provision shall be made so that, upon the basis and the
          terms and in the manner provided in this Warrant, the
          holder of this Warrant, upon the exercise hereof at any
          time after the consummation of such transaction, shall be
          entitled to receive (at the aggregate Warrant Price in
          effect at the time of such consummation for all Common
          Stock or Other Securities issuable upon such exercise
          immediately prior to such consummation), in lieu of the
          Common Stock or Other Securities issuable upon such
          exercise prior to such consummation, the highest amount
          of securities, cash or other property to which such
          holder would actually have been entitled as a shareholder
          upon such consummation if such holder had exercised the
          rights represented by this Warrant immediately prior
          thereto, subject to adjustments (subsequent to such
          consummation) as nearly equivalent as possible to the
          adjustments provided for in sections 2 through 4.

                    3.2.  Assumption of Obligations. 
          Notwithstanding anything contained in the Warrants or in
          the Purchase Agreement to the contrary, the Company will
          not effect any of the transactions described in clauses
          (a) through (d) of section 3.1 unless, prior to the
          consummation thereof, each Person (other than the
          Company) which may be required to deliver any stock,
          securities, cash or property upon the exercise of this
          Warrant as provided herein shall assume, by written
          instrument delivered to, and reasonably satisfactory to,
          the holder of this Warrant, (a) the obligations of the
          Company under this Warrant (and if the Company shall
          survive the consummation of such transaction, such
          assumption shall be in addition to, and shall not release
          the Company from, any continuing obligations of the
          Company under this Warrant), (b) the obligations of the
          Company under the Registration Rights Agreement and (c)
          the obligation to deliver to such holder such shares of
          stock, securities, cash or property as, in accordance
          with the foregoing provisions of this section 3, such
          holder may be entitled to receive, and such Person shall
          have similarly delivered to such holder an opinion of
          counsel for such Person, which counsel shall be
          reasonably satisfactory to such holder, stating that this
          Warrant shall thereafter continue in full force and
          effect and the terms hereof (including, without
          limitation, all of the provisions of this section 3)
          shall be applicable to the stock, securities, cash or
          property which such Person may be required to deliver
          upon any exercise of this Warrant or the exercise of any
          rights pursuant hereto.  Nothing in this section 3 shall
          be deemed to authorize the Company to enter into any
          transaction not otherwise permitted by the Purchase
          Agreement.

                    4.  Other Dilutive Events.  In case any event
          shall occur as to which the provisions of section 2 or
          section 3 are not strictly applicable but the failure to
          make any adjustment would not fairly protect the purchase
          rights represented by this Warrant in accordance with the
          essential intent and principles of such sections, then,
          in each such case, the Company shall appoint a firm of
          independent certified public accountants of recognized
          national standing (such firm to be subject to the
          approval of Wand/Nestor Investments L.P.), which shall
          give their opinion regarding the adjustment, if any, on a
          basis consistent with the essential intent and principles
          established in sections 2 and 3, necessary to preserve,
          without dilution, the purchase rights represented by this
          Warrant.  Upon receipt of such opinion, the Company will
          promptly mail a copy thereof to the holder of this
          Warrant and shall make the adjustments described therein.

                    5.  No Dilution or Impairment.  The Company
          will not, by amendment of its certificate of
          incorporation or through any consolidation, merger,
          reorganization, transfer of assets, dissolution, issue or
          sale of securities or any other voluntary action, avoid
          or seek to avoid the observance or performance of any of
          the terms of this Warrant, but will at all times in good
          faith assist in the carrying out of all such terms and in
          the taking of all such action as may be necessary or
          appropriate in order to protect the rights of the holder
          of this Warrant against dilution or other impairment. 
          Without limiting the generality of the foregoing, the
          Company (a) will not permit the par value of any shares
          of stock receivable upon the exercise of this Warrant to
          exceed the amount payable therefor upon such exercise,
          (b) will take all such action as may be necessary or
          appropriate in order that the Company may validly and
          legally issue fully paid and nonassessable shares of
          stock on the exercise of the Warrants from time to time
          outstanding, and (c) will not take any action which
          results in any adjustment of the Warrant Price if the
          total number of shares of Common Stock (or Other
          Securities) issuable after the action upon the exercise
          of all of the Warrants would exceed the total number of
          shares of Common Stock (or Other Securities) then
          authorized by the Company's certificate of incorporation
          and available for the purpose of issue upon such
          exercise.

                    6.  Accountants' Report as to Adjustments.  In
          each case of any adjustment or readjustment in the shares
          of Common Stock (or Other Securities) issuable upon the
          exercise of this Warrant, the Company at its expense will
          promptly compute such adjustment or readjustment in
          accordance with the terms of this Warrant and cause
          independent certified public accountants of recognized
          standing (such firm to be subject to the approval of
          Wand/Nestor Investments L.P.) selected by the Company to
          verify such computation and prepare a report setting
          forth such adjustment or readjustment and showing in
          reasonable detail the method of calculation thereof and
          the facts upon which such adjustment or readjustment is
          based, including a statement of (a) the consideration
          received or to be received by the Company for any
          Additional Shares of Common Stock issued or sold or
          deemed to have been issued, (b) the number of shares of
          Common Stock outstanding or deemed to be outstanding, and
          (c) the Warrant Price in effect immediately prior to such
          issue or sale and as adjusted and readjusted (if required
          by section 2) on account thereof.  The Company will
          forthwith mail a copy of each such report to each holder
          of a Warrant and will, upon the written request at any
          time of any holder of a Warrant, furnish to such holder a
          like report setting forth the Warrant Price at the time
          in effect and showing in reasonable detail how it was
          calculated.  The Company will also keep copies of all
          such reports at its principal office and will cause the
          same to be available for inspection at such office during
          normal business hours by any holder of a Warrant or any
          prospective purchaser of a Warrant designated by the
          holder thereof.

                    7.  Notices of Corporate Action.  In the event of
                    (a)  any taking by the Company of a record of
               the holders of any class of securities for the
               purpose of determining the holders thereof who are
               entitled to receive any dividend (other than a
               regular periodic dividend payable in cash out of
               earned surplus in an amount not exceeding the amount
               of the immediately preceding cash dividend for such
               period) or other distribution, or any right to
               subscribe for, purchase or otherwise acquire any
               shares of stock of any class or any other securities
               or property, or to receive any other right, or 

                    (b)  any capital reorganization of the Company,
               any reclassification or recapitalization of the
               capital stock of the Company or any consolidation or
               merger involving the Company and any other Person or
               any transfer of all or substantially all the assets
               of the Company to any other Person, or

                    (c)  any voluntary or involuntary dissolution,
               liquidation or winding-up of the Company,

          the Company will mail to each holder of a Warrant a
          notice specifying (i) the date or expected date on which
          any such record is to be taken for the purpose of such
          dividend, distribution or right, and the amount and
          character of such dividend, distribution or right, and
          (ii) the date or expected date on which any such
          reorganization, reclassification, recapitalization,
          consolidation, merger, transfer, dissolution, liquidation
          or winding-up is to take place and the time, if any such
          time is to be fixed, as of which the holders of record of
          Common Stock (or Other Securities) shall be entitled to
          exchange their shares of Common Stock (or Other
          Securities) for the securities or other property
          deliverable upon such reorganization, reclassification,
          recapitalization, consolidation, merger, transfer,
          dissolution, liquidation or winding-up.  Such notice
          shall be mailed at least 45 days prior to the date
          therein specified.

                    8.  Registration of Common Stock.  If any
          shares of Common Stock required to be reserved for
          purposes of exercise of this Warrant require registration
          with or approval of any governmental authority under any
          federal or state law (other than the Securities Act)
          before such shares may be issued upon exercise, the
          Company will, at its expense and as expeditiously as
          possible, use its best efforts to cause such shares to be
          duly registered or approved, as the case may be.  The
          shares of Common Stock (and Other Securities) issuable
          upon exercise of this Warrant (or upon conversion of any
          shares of Common Stock issued upon such exercise) shall
          constitute Registrable Securities (as such term is
          defined in the Registration Rights Agreement).  Each
          holder of this Warrant shall be entitled to all of the
          benefits afforded to a holder of any such Registrable
          Securities under the Registration Rights Agreement and
          such holder, by its acceptance of this Warrant, agrees to
          be bound by and to comply with the terms and conditions
          of the Registration Rights Agreement applicable to such
          holder as a holder of such Registrable Securities.  At
          any such time as Common Stock is listed on any national
          securities exchange, the Company will, at its expense,
          obtain promptly and maintain the approval for listing on
          each such exchange, upon official notice of issuance, the
          shares of Common Stock issuable upon exercise of the then
          outstanding Warrants and maintain the listing of such
          shares after their issuance; and the Company will also
          list on such national securities exchange, will register
          under the Exchange Act and will maintain such listing of,
          any Other Securities that at any time are issuable upon
          exercise of the Warrants, if and at the time that any
          securities of the same class shall be listed on such
          national securities exchange by the Company.

                    9.2.  Restrictions on Transfer By BHCA Holders. 
          A BHCA Holder may only transfer this Warrant, in whole
          or in part, to an unaffiliated third party (a) in a
          widely dispersed public offering, (b) to one or more
          investors, in one or more transactions, none of whom,
          after such purchase would hold more than 2% of the voting
          securities of the Company then outstanding assuming that
          the Warrants being transferred to such investor have been
          fully exercised by such investor, (c) to any Person that
          already controls the Company prior to such transfer, (d)
          in a transaction that complies with Rule 144 (or any
          successor thereto) of the Securities Act of 1933, as
          amended, or (e) in any other transaction approved in
          advance by the Federal Reserve System.

                    10.  Availability of Information.  The Company
          shall timely file the reports required to be filed by it
          under the Securities Act and the Exchange Act (including
          but not limited to the reports under sections 13 and
          15(d) of the Exchange Act referred to in subparagraph (c)
          of Rule 144 adopted by the Commission under the
          Securities Act) and the rules and regulations adopted by
          the Commission thereunder (or, if the Company is not
          required to file such reports, will, upon the request of
          any holder of Registrable Securities, make publicly
          available other information) and will take such further
          action as any holder of Registrable Securities may
          reasonably request, all to the extent required from time
          to time to enable such holder to sell Registrable
          Securities without registration under the Securities Act
          within the limitation of the exemptions provided by (a)
          Rule 144 under the Securities Act, as such Rule may be
          amended from time to time, or (b) any similar rule or
          regulation hereafter adopted by the Commission.  Upon the
          request of any holder of Registrable Securities, the
          Company will deliver to such holder a written statement
          as to whether it has complied with the requirements of
          this section 10.

                    11.  Reservation of Stock, etc.  The Company
          will at all times reserve and keep available, solely for
          issuance and delivery upon exercise of the Warrants, the
          number of shares of Common Stock (or Other Securities)
          from time to time issuable upon exercise of all Warrants
          at the time outstanding.  All shares of Common Stock (or
          Other Securities) issuable upon exercise of any Warrants
          shall be duly authorized and, when issued upon such
          exercise, shall be validly issued and, in the case of
          shares, fully paid and nonassessable with no liability on
          the part of the holders thereof.

                    12.  Registration and Transfer of Warrants,
          etc.

                    12.1. Warrant Register; Ownership of Warrants. 
          The Company will keep at its principal office a register
          in which the Company will provide for the registration of
          Warrants and the registration of transfers of Warrants. 
          The Company may treat the Person in whose name any
          Warrant is registered on such register as the owner
          thereof for all other purposes, and the Company shall not
          be affected by any notice to the contrary, except that,
          if and when any Warrant is properly assigned in blank,
          the Company may (but shall not be obligated to) treat the
          bearer thereof as the owner of such Warrant for all
          purposes.  Subject to section 9, a Warrant, if properly
          assigned, may be exercised by a new holder without a new
          Warrant first having been issued.

                    12.2.  Transfer and Exchange of Warrants.  Upon
          surrender of any Warrant for registration of transfer or
          for exchange to the Company at its principal office, the
          Company at its expense will (subject to compliance with
          section 9, if applicable) execute and deliver in exchange
          therefor a new Warrant or Warrants of like tenor, in the
          name of such holder or as such holder (upon payment by
          such holder of any applicable transfer taxes) may direct,
          calling in the aggregate on the face or faces thereof for
          the number of shares of Common Stock called for on the
          face or faces of the Warrant or Warrants so surrendered. 

                    12.3.  Replacement of Warrants.  Upon receipt
          of evidence reasonably satisfactory to the Company of the
          loss, theft, destruction or mutilation of any Warrant
          and, in the case of any such loss, theft or destruction
          of any Warrant, upon delivery of an indemnity bond in
          such reasonable amount as the Company may determine or,
          in the case of any such mutilation, upon the surrender of
          such Warrant for cancellation to the Company at its
          principal office, the Company at its expense will execute
          and deliver, in lieu thereof, a new Warrant of like
          tenor.  

                    13.  Registration Rights.  Wand or any assignee
          of this Warrant shall be entitled to all rights and
          benefits regarding the registration of Common Stock and
          Registrable Securities set forth in the Registration
          Rights Agreement.

          not subsequently reacquired or retired by the Company,

               the purchase of an aggregate of 849,875 shares of
               Common Stock (based on the current capitalization of
               the Company);

               combination, reclassification, stocksplit, dividend
               or recapitalization of the Company) issued upon the

               option, compensation  or purchase plan or plans
               adopted or assumed after such date,

                    (e)  such additional number of shares as may

               securities referred to in the foregoing clauses (a)
               through (d) by reason of adjustments required
               pursuant to anti-dilution provisions applicable to
               such securities as in effect on the date hereof, but
               only if and to the extent that such adjustments are

               in Common Stock.

               Other Securities) to which such holder shall be
               entitled upon such exercise plus, in lieu of any
               fractional share to which such holder would
               otherwise be entitled, cash in an amount equal to
               the same fraction of the Market Price per share on
               the Business Day next preceding the date of such
               exercise, and

                    (b)  in case such exercise is in part only, a
               new Warrant or Warrants of like tenor, calling in
               the aggregate on the face or faces thereof for the
               number of shares of Common Stock equal (without
               giving effect to any adjustment thereof) to the
               number of such shares called for on the face of this
               Warrant minus the number of such shares designated
               by the holder upon such exercise as provided in
               section 1.1.

                    1.4.  Company to Reaffirm Obligations.  The
          Company will, at the time of each exercise of this
          Warrant, upon the request of the holder hereof,
          acknowledge in writing its continuing obligation to
          afford to such holder all rights (including, without
          limitation, any rights to registration, pursuant to the
          Registration Rights Agreement referred to in section 8,
          of the shares of Common Stock or Other Securities issued
          upon such exercise) to which such holder shall continue
          to be entitled after such exercise in accordance with the
          terms of this Warrant, provided that if the holder of
          this Warrant shall fail to make any such request, such
          failure shall not affect the continuing obligation of the
          Company to afford such rights to such holder.

                    1.5.  Payment by Application of Shares
          Otherwise Issuable.  Upon any exercise of this Warrant,
          the holder hereof may, at its option, instruct the
          Company, by written notice accompanying the surrender of
          this Warrant at the time of such exercise, to apply to
          the payment required by section 1.1 such number of the
          shares of Common Stock otherwise issuable to such holder
          upon such exercise as shall be specified in such notice,
          in which case an amount equal to the excess of the
          aggregate Current Market Price of such specified number
          of shares on the date of exercise over the portion of the
          payment required by section 1.1 attributable to such
          shares shall be deemed to have been paid to the Company
          and the number of shares issuable upon such exercise
          shall be reduced by such specified number.

                    1.6.  Restrictions Upon Exercise by BHCA
          Holders.  A BHCA Holder may only exercise this Warrant,
          in whole or in part, in connection with the sale of the
          Common Stock issuable upon the exercise of the Warrant to
          an unaffiliated third party (a) in a widely dispersed
          public offering, (b) to one or more investors, in one or
          more transactions, none of whom, after such purchase
          would hold more than 2% of the voting securities of the
          Company then outstanding, (c) to any Person that already
          controls the Company prior to such transfer, (d) in a
          transaction that complies with Rule 144 (or any successor
          thereto) of the Securities Act of 1933, as amended, or
          (e) in any other transaction approved in advance by the
          Federal Reserve System.

                    2.  Adjustment of Common Stock Issuable Upon
          Exercise.  2.1.  General; Warrant Price.  The number of
          shares of Common Stock which the holder of this Warrant
          shall be entitled to receive upon each exercise hereof
          shall be determined by multiplying the number of shares
          of Common Stock which would otherwise (but for the
          provisions of this section 2) be issuable upon such
          exercise, as designated by the holder hereof pursuant to
          section 1.1, by the fraction of which (a) the numerator
          is $1.00 and (b) the denominator is the Warrant Price in
          effect on the date of such exercise.  The "Warrant Price"
          shall initially be $1.00 per share, shall be adjusted and
          readjusted from time to time as provided in this section
          2 and, as so adjusted or readjusted, shall remain in
          effect until a further adjustment or readjustment thereof
          is required by this section 2.

                    2.2.  Adjustment of Warrant Price.

                    2.2.1  Issuance of Additional Shares of Common
          Stock.  In case the Company at any time or from time to
          time after the date hereof shall issue or sell Additional
          Shares of Common Stock (including Additional Shares of
          Common Stock deemed to be issued pursuant to section 2.3
          or 2.4) without consideration or for a consideration per
          share less than the Warrant Price in effect immediately
          prior to such issue or sale, then, and in each such case,
          subject to section 2.8, such Warrant Price shall be
          reduced, concurrently with such issue or sale, to a price
          (calculated to the nearest .001 of a cent) determined by
          multiplying such Warrant Price by a fraction

                    (a)  the numerator of which shall be (i) the
               number of shares of Common Stock outstanding
               immediately prior to such issue or sale plus (ii)
               the number of shares of Common Stock which the
               aggregate consideration received by the Company for
               the total number of such Additional Shares of Common
               Stock so issued or sold would purchase at such
               Warrant Price, and

                    (b)  the denominator of which shall be the
               number of shares of Common Stock outstanding
               immediately after such issue or sale,

          provided that, for the purposes of this section 2.2.1,
          (x) immediately after any Additional Shares of Common
          Stock are deemed to have been issued pursuant to section
          2.3 or 2.4, such Additional Shares shall be deemed to be
          outstanding, and (y) treasury shares shall not be deemed
          to be outstanding.

                    2.2.2  Extraordinary Dividends and
          Distributions.  In case the Company at any time or from
          time to time after the date hereof shall declare, order,
          pay or make a dividend or other distribution (including,
          without limitation, any distribution of other or
          additional stock or other securities or property or
          Options by way of dividend or spin-off, reclassification,
          recapitalization or similar corporate rearrangement) on
          the Common Stock, other than a dividend payable in (a)
          Additional Shares of Common Stock or (b) cash dividends
          during any fiscal year of the Company that do not exceed
          twenty percent (20%) of the after tax earnings per share
          of the Common Stock for the immediately preceding fiscal
          year of the Company, then, and in each such case, subject
          to section 2.8, the Warrant Price in effect immediately
          prior to the close of business on the record date fixed
          for the determination of holders of any class of
          securities entitled to receive such dividend or
          distribution shall be reduced, effective as of the close
          of business on such record date, to a price (calculated
          to the nearest .001 of a cent) determined by multiplying
          such Warrant Price by a fraction

                    (x)  the numerator of which shall be the
               Current Market Price in effect on such record date
               or, if the Common Stock trades on an ex-dividend
               basis, on the date prior to the commencement of ex-
               dividend trading, less the amount of such dividend
               or distribution (as determined in good faith by the
               Board of Directors of the Company, subject to 
               confirmation by a firm of independent certified
               public accountants of recognized national standing
               approved by Wand/Nestor Investments L.P.) applicable
               to one share of Common Stock, and

                    (y)  the denominator of which shall be such
               Current Market Price.

                    2.3.  Treatment of Options and Convertible
          Securities.  In case the Company at any time or from time
          to time after the date hereof shall issue, sell, grant or
          assume, or shall fix a record date for the determination
          of holders of any class of securities entitled to
          receive, any Options or Convertible Securities, then, and
          in each such case, the maximum number of Additional
          Shares of Common Stock (as set forth in the instrument
          relating thereto, without regard to any provisions
          contained therein for a subsequent adjustment of such
          number) issuable upon the exercise of such Options or, in
          the case of Convertible Securities and Options therefor,
          the conversion or exchange of such Convertible
          Securities, shall be deemed to be Additional Shares of
          Common Stock issued as of the time of such issue, sale,
          grant or assumption or, in case such a record date shall
          have been fixed, as of the close of business on such
          record date (or, if the Common Stock trades on an ex-
          dividend basis, on the date prior to the commencement of
          ex-dividend trading), provided that such Additional
          Shares of Common Stock shall not be deemed to have been
          issued unless the consideration per share (determined
          pursuant to section 2.5) of such shares would be less
          than the Warrant Price in effect on the date of and
          immediately prior to such issue, sale, grant or
          assumption or immediately prior to the close of business
          on such record date (or, if the Common Stock trades on an
          ex-dividend basis, on the date prior to the commencement
          of ex-dividend trading), as the case may be, and
          provided, further, that in any such case in which
          Additional Shares of Common Stock are deemed to be issued

                    (a)  no further adjustment of the Warrant Price
               shall be made upon the subsequent issue or sale of
               Convertible Securities or shares of Common Stock
               upon the exercise of such Options or the conversion
               or exchange of such Convertible Securities;

                    (b)  if such Options or Convertible Securities
               by their terms provide, with the passage of time or
               otherwise, for any increase in the consideration
               payable to the Company, or decrease in the number of
               Additional Shares of Common Stock issuable, upon the
               exercise, conversion or exchange thereof (by change
               of rate or otherwise), the Warrant Price computed
               upon the original issue, sale, grant or assumption
               thereof (or upon the occurrence of the record date,
               or date prior to the commencement of ex-dividend
               trading, as the case may be, with respect thereto),
               and any subsequent adjustments based thereon, shall,
               upon any such increase or decrease becoming
               effective, be recomputed to reflect such increase or
               decrease insofar as it affects such Options, or the
               rights of conversion or exchange under such
               Convertible Securities, which are outstanding at
               such time;

                    (c)  upon the expiration (or purchase by the
               Company and cancellation or retirement) of any such
               Options which shall not have been exercised or the
               expiration of any rights of conversion or exchange
               under any such Convertible Securities which (or
               purchase by the Company and cancellation or
               retirement of any such Convertible Securities the
               rights of conversion or exchange under which) shall
               not have been exercised, the Warrant Price computed
               upon the original issue, sale, grant or assumption
               thereof (or upon the occurrence of the record date,
               or date prior to the commencement of ex-dividend
               trading, as the case may be, with respect thereto),
               and any subsequent adjustments based thereon, shall,
               upon such expiration (or such cancellation or
               retirement, as the case may be), be recomputed as
               if:

                         (i)  in the case of Options for Common
                    Stock or Convertible Securities, the only
                    Additional Shares of Common Stock issued or
                    sold were the Additional Shares of Common
                    Stock, if any, actually issued or sold upon the
                    exercise of such Options or the conversion or
                    exchange of such Convertible Securities and the
                    consideration received therefor was the
                    consideration actually received by the Company
                    for the issue, sale, grant or assumption of all
                    such Options, whether or not exercised, plus
                    the consideration actually received by the
                    Company upon such exercise, or for the issue or
                    sale of all such Convertible Securities which
                    were actually converted or exchanged, plus the
                    additional consideration, if any, actually
                    received by the Company upon such conversion or
                    exchange, and

                         (ii) in the case of Options for
                    Convertible Securities, only the Convertible
                    Securities, if any, actually issued or sold
                    upon the exercise of such Options were issued
                    at the time of the issue, sale, grant or
                    assumption of such Options, and the
                    consideration received by the Company for the
                    Additional Shares of Common Stock deemed to
                    have then been issued was the consideration
                    actually received by the Company for the issue,
                    sale, grant or assumption of all such Options,
                    whether or not exercised, plus the
                    consideration deemed to have been received by
                    the Company (pursuant to section 2.5) upon the
                    issue or sale of such Convertible Securities
                    with respect to which such Options were
                    actually exercised;

                    (d)  no readjustment pursuant to subdivision
               (b) or (c) above shall have the effect of increasing
               the Warrant Price by an amount in excess of the
               amount of the adjustment thereof originally made in
               respect of the issue, sale, grant or assumption of
               such Options or Convertible Securities; and 

                    (e)  in the case of any such Options which
               expire by their terms not more than 30 days after
               the date of issue, sale, grant or assumption
               thereof, no adjustment of the Warrant Price shall be
               made until the expiration or exercise of all such
               Options, whereupon such adjustment shall be made in
               the manner provided in subdivision (c) above.

                    2.4.  Treatment of Stock Dividends, Stock
          Splits, etc.  In case the Company at any time or from
          time to time after the date hereof shall declare or pay
          any dividend on the Common Stock payable in Common Stock,
          or shall effect a subdivision of the outstanding shares
          of Common Stock into a greater number of shares of Common
          Stock (by reclassification or otherwise than by payment
          of a dividend in Common Stock), then, and in each such
          case, Additional Shares of Common Stock shall be deemed
          to have been issued (a) in the case of any such dividend,
          immediately after the close of business on the record
          date for the determination of holders of any class of
          securities entitled to receive such dividend, or (b) in
          the case of any such subdivision, at the close of
          business on the day immediately prior to the day upon
          which such corporate action becomes effective.

                    2.5.  Computation of Consideration.  For the
          purposes of this section 2,

                    (a)  the consideration for the issue or sale of
               any Additional Shares of Common Stock shall,
               irrespective of the accounting treatment of such
               consideration,

                         (i)  insofar as it consists of cash, be
                    computed at the net amount of cash received by
                    the Company, without deducting any expenses
                    paid or incurred by the Company or any
                    commissions or compensation paid or concessions
                    or discounts allowed to underwriters, dealers
                    or others performing similar services in
                    connection with such issue or sale,

                         (ii)  insofar as it consists of property
                    (including securities) other than cash, be
                    computed at the fair value thereof at the time
                    of such issue or sale, as determined in good
                    faith by the Board of Directors of the Company
                    (subject to  confirmation by a firm of
                    independent certified public accountants of
                    recognized  standing approved by Wand/Nestor
                    Investments L.P.), and 

                         (iii)  in case Additional Shares of Common
                    Stock are issued or sold together with other
                    stock or securities or other assets of the
                    Company for a consideration which covers both,
                    be the portion of such consideration so
                    received, computed as provided in clauses (i)
                    and (ii) above, allocable to such Additional
                    Shares of Common Stock, all as determined in
                    good faith by the Board of Directors of the
                    Company (subject to  confirmation by a firm of
                    independent certified public accountants of
                    recognized  standing approved by Wand/Nestor
                    Investments L.P.);

                    (b)  Additional Shares of Common Stock deemed
               to have been issued pursuant to section 2.3,
               relating to Options and Convertible Securities,
               shall be deemed to have been issued for a
               consideration per share determined by dividing

                         (i)  the total amount, if any, received
                    and receivable by the Company as consideration
                    for the issue, sale, grant or assumption of the
                    Options or Convertible Securities in question,
                    plus the minimum aggregate amount of additional
                    consideration (as set forth in the instruments
                    relating thereto, without regard to any
                    provision contained therein for a subsequent
                    adjustment of such consideration to protect
                    against dilution) payable to the Company upon
                    the exercise in full of such Options or the
                    conversion or exchange of such Convertible
                    Securities or, in the case of Options for
                    Convertible Securities, the exercise of such
                    Options for Convertible Securities and the
                    conversion or exchange of such Convertible
                    Securities, in each case computing such
                    consideration as provided in the foregoing
                    subdivision (a),

          by

                         (ii)  the maximum number of shares of
                    Common Stock (as set forth in the instruments
                    relating thereto, without regard to any
                    provision contained therein for a subsequent
                    adjustment of such number to protect against
                    dilution) issuable upon the exercise of such
                    Options or the conversion or exchange of such
                    Convertible Securities; and

                    (c)  Additional Shares of Common Stock deemed
               to have been issued pursuant to section 2.4,
               relating to stock dividends, stock splits, etc.,
               shall be deemed to have been issued for no
               consideration.

                    2.6.  Adjustments for Combinations, etc.  In
          case the outstanding shares of Common Stock shall be
          combined or consolidated, by reclassification or
          otherwise, into a lesser number of shares of Common
          Stock, the Warrant Price in effect immediately prior to
          such combination or consolidation shall, concurrently
          with the effectiveness of such combination or
          consolidation, be proportionately increased.

                    2.7.  Dilution in Case of Other Securities.  In
          case any Other Securities shall be issued or sold or
          shall become subject to issue or sale upon the conversion
          or exchange of any stock (or Other Securities) of the
          Company (or any issuer of Other Securities or any other
          Person referred to in section 3) or to subscription,
          purchase or other acquisition pursuant to any Options
          issued or granted by the Company (or any such other
          issuer or Person) for a consideration such as to dilute,
          on a basis consistent with the standards established in
          the other provisions of this section 2, the purchase
          rights granted by this Warrant, then, and in each such
          case, the computations, adjustments and readjustments
          provided for in this section 2 with respect to the
          Warrant Price shall be made as nearly as possible in the
          manner so provided and applied to determine the amount of
          Other Securities from time to time receivable upon the
          exercise of the Warrants, so as to protect the holders of
          the Warrants against the effect of such dilution.

                    2.8.  Minimum Adjustment of Warrant Price.  If
          the amount of any adjustment of the Warrant Price
          required pursuant to this section 2 would be less than
          one percent (1%) of the Warrant Price in effect at the
          time such adjustment is otherwise so required to be made,
          such amount shall be carried forward and adjustment with
          respect thereto made at the time of and together with any
          subsequent adjustment which, together with such amount
          and any other amount or amounts so carried forward, shall
          aggregate at least one percent (1%) of such Warrant
          Price.

                    3.  Consolidation, Merger, etc.  3.1.  
          Adjustments for Consolidation, Merger, Sale of Assets,
          Reorganization, etc.  In case the Company after the date
          hereof (a) shall consolidate with or merge into any other
          Person and shall not be the continuing or surviving
          corporation of such consolidation or merger, or (b) shall
          permit any other Person to consolidate with or merge into
          the Company and the Company shall be the continuing or
          surviving Person but, in connection with such
          consolidation or merger, the Common Stock or Other
          Securities shall be changed into or exchanged for stock
          or other securities of any other Person or cash or any
          other property, or (c) shall transfer all or
          substantially all of its properties or assets to any
          other Person, or (d) shall effect a capital
          reorganization or reclassification of the Common Stock or
          Other Securities (other than a capital reorganization or
          reclassification resulting in the issue of Additional
          Shares of Common Stock for which adjustment in the
          Warrant Price is provided in section 2.2.1 or 2.2.2),
          then, and in the case of each such transaction, proper
          provision shall be made so that, upon the basis and the
          terms and in the manner provided in this Warrant, the
          holder of this Warrant, upon the exercise hereof at any
          time after the consummation of such transaction, shall be
          entitled to receive (at the aggregate Warrant Price in
          effect at the time of such consummation for all Common
          Stock or Other Securities issuable upon such exercise
          immediately prior to such consummation), in lieu of the
          Common Stock or Other Securities issuable upon such
          exercise prior to such consummation, the highest amount
          of securities, cash or other property to which such
          holder would actually have been entitled as a shareholder
          upon such consummation if such holder had exercised the
          rights represented by this Warrant immediately prior
          thereto, subject to adjustments (subsequent to such
          consummation) as nearly equivalent as possible to the
          adjustments provided for in sections 2 through 4.

                    3.2.  Assumption of Obligations. 
          Notwithstanding anything contained in the Warrants or in
          the Purchase Agreement to the contrary, the Company will
          not effect any of the transactions described in clauses
          (a) through (d) of section 3.1 unless, prior to the
          consummation thereof, each Person (other than the
          Company) which may be required to deliver any stock,
          securities, cash or property upon the exercise of this
          Warrant as provided herein shall assume, by written
          instrument delivered to, and reasonably satisfactory to,
          the holder of this Warrant, (a) the obligations of the
          Company under this Warrant (and if the Company shall
          survive the consummation of such transaction, such
          assumption shall be in addition to, and shall not release
          the Company from, any continuing obligations of the
          Company under this Warrant), (b) the obligations of the
          Company under the Registration Rights Agreement and (c)
          the obligation to deliver to such holder such shares of
          stock, securities, cash or property as, in accordance
          with the foregoing provisions of this section 3, such
          holder may be entitled to receive, and such Person shall
          have similarly delivered to such holder an opinion of
          counsel for such Person, which counsel shall be
          reasonably satisfactory to such holder, stating that this
          Warrant shall thereafter continue in full force and
          effect and the terms hereof (including, without
          limitation, all of the provisions of this section 3)
          shall be applicable to the stock, securities, cash or
          property which such Person may be required to deliver
          upon any exercise of this Warrant or the exercise of any
          rights pursuant hereto.

                    4.  Other Dilutive Events.  In case any event
          shall occur as to which the provisions of section 2 or
          section 3 are not strictly applicable but the failure to
          make any adjustment would not fairly protect the purchase
          rights represented by this Warrant in accordance with the
          essential intent and principles of such sections, then,
          in each such case, the Company shall appoint a firm of
          independent certified public accountants of recognized
          national standing (such firm to be subject to the
          approval of Wand/Nestor Investments L.P.), which shall
          give their opinion regarding the adjustment, if any, on a
          basis consistent with the essential intent and principles
          established in sections 2 and 3, necessary to preserve,
          without dilution, the purchase rights represented by this
          Warrant.  Upon receipt of such opinion, the Company will
          promptly mail a copy thereof to the holder of this
          Warrant and shall make the adjustments described therein.

                    5.  No Dilution or Impairment.  The Company
          will not, by amendment of its certificate of
          incorporation or through any consolidation, merger,
          reorganization, transfer of assets, dissolution, issue or
          sale of securities or any other voluntary action, avoid
          or seek to avoid the observance or performance of any of
          the terms of this Warrant, but will at all times in good
          faith assist in the carrying out of all such terms and in
          the taking of all such action as may be necessary or
          appropriate in order to protect the rights of the holder
          of this Warrant against dilution or other impairment. 
          Without limiting the generality of the foregoing, the
          Company (a) will not permit the par value of any shares
          of stock receivable upon the exercise of this Warrant to
          exceed the amount payable therefor upon such exercise,
          (b) will take all such action as may be necessary or
          appropriate in order that the Company may validly and
          legally issue fully paid and nonassessable shares of
          stock on the exercise of the Warrants from time to time
          outstanding, and (c) will not take any action which
          results in any adjustment of the Warrant Price if the
          total number of shares of Common Stock (or Other
          Securities) issuable after the action upon the exercise
          of all of the Warrants would exceed the total number of
          shares of Common Stock (or Other Securities) then
          authorized by the Company's certificate of incorporation
          and available for the purpose of issue upon such
          exercise.

                    6.  Accountants' Report as to Adjustments.  In
          each case of any adjustment or readjustment in the shares
          of Common Stock (or Other Securities) issuable upon the
          exercise of this Warrant, the Company at its expense will
          promptly compute such adjustment or readjustment in
          accordance with the terms of this Warrant and cause
          independent certified public accountants of recognized
          standing (such firm to be subject to the approval of
          Wand/Nestor Investments L.P.) selected by the Company to
          verify such computation and prepare a report setting
          forth such adjustment or readjustment and showing in
          reasonable detail the method of calculation thereof and
          the facts upon which such adjustment or readjustment is
          based, including a statement of (a) the consideration
          received or to be received by the Company for any
          Additional Shares of Common Stock issued or sold or
          deemed to have been issued, (b) the number of shares of
          Common Stock outstanding or deemed to be outstanding, and
          (c) the Warrant Price in effect immediately prior to such
          issue or sale and as adjusted and readjusted (if required
          by section 2) on account thereof.  The Company will
          forthwith mail a copy of each such report to each holder
          of a Warrant and will, upon the written request at any
          time of any holder of a Warrant, furnish to such holder a
          like report setting forth the Warrant Price at the time
          in effect and showing in reasonable detail how it was
          calculated.  The Company will also keep copies of all
          such reports at its principal office and will cause the
          same to be available for inspection at such office during
          normal business hours by any holder of a Warrant or any
          prospective purchaser of a Warrant designated by the
          holder thereof.

                    7.  Notices of Corporate Action.  In the event
          of 
                    (a)  any taking by the Company of a record of
               the holders of any class of securities for the
               purpose of determining the holders thereof who are
               entitled to receive any dividend (other than a
               regular periodic dividend payable in cash out of
               earned surplus in an amount not exceeding the amount
               of the immediately preceding cash dividend for such
               period) or other distribution, or any right to
               subscribe for, purchase or otherwise acquire any
               shares of stock of any class or any other securities
               or property, or to receive any other right, or 

                    (b)  any capital reorganization of the Company,
               any reclassification or recapitalization of the
               capital stock of the Company or any consolidation or
               merger involving the Company and any other Person or
               any transfer of all or substantially all the assets
               of the Company to any other Person, or

                    (c)  any voluntary or involuntary dissolution,
               liquidation or winding-up of the Company,

          the Company will mail to each holder of a Warrant a
          notice specifying (i) the date or expected date on which
          any such record is to be taken for the purpose of such
          dividend, distribution or right, and the amount and
          character of such dividend, distribution or right, and
          (ii) the date or expected date on which any such
          reorganization, reclassification, recapitalization,
          consolidation, merger, transfer, dissolution, liquidation
          or winding-up is to take place and the time, if any such
          time is to be fixed, as of which the holders of record of
          Common Stock (or Other Securities) shall be entitled to
          exchange their shares of Common Stock (or Other
          Securities) for the securities or other property
          deliverable upon such reorganization, reclassification,
          recapitalization, consolidation, merger, transfer,
          dissolution, liquidation or winding-up.  Such notice
          shall be mailed at least 45 days prior to the date
          therein specified.

                    8.  Registration of Common Stock.  If any
          shares of Common Stock required to be reserved for
          purposes of exercise of this Warrant require registration
          with or approval of any governmental authority under any
          federal or state law (other than the Securities Act)
          before such shares may be issued upon exercise, the
          Company will, at its expense and as expeditiously as
          possible, use its best efforts to cause such shares to be
          duly registered or approved, as the case may be.  The
          shares of Common Stock (and Other Securities) issuable
          upon exercise of this Warrant (or upon conversion of any
          shares of Common Stock issued upon such exercise) shall
          constitute Registrable Securities (as such term is
          defined in the Registration Rights Agreement).  Each
          holder of this Warrant shall be entitled to all of the
          benefits afforded to a holder of any such Registrable
          Securities under the Registration Rights Agreement and
          such holder, by its acceptance of this Warrant, agrees to
          be bound by and to comply with the terms and conditions
          of the Registration Rights Agreement applicable to such
          holder as a holder of such Registrable Securities.  At
          any such time as Common Stock is listed on any national
          securities exchange, the Company will, at its expense,
          obtain promptly and maintain the approval for listing on
          each such exchange, upon official notice of issuance, the
          shares of Common Stock issuable upon exercise of the then
          outstanding Warrants and maintain the listing of such
          shares after their issuance; and the Company will also
          list on such national securities exchange, will register
          under the Exchange Act and will maintain such listing of,
          any Other Securities that at any time are issuable upon
          exercise of the Warrants, if and at the time that any
          securities of the same class shall be listed on such
          national securities exchange by the Company.

                    9.  Restrictions on Transfer.  9.1. 
          Restrictive Legends.  Except as otherwise permitted by
          this section 9, each Warrant (including each Warrant
          issued upon the transfer of any Warrant) shall be stamped

          following form:

                    9.2.  Restrictions on Transfer By BHCA Holders. 
          A BHCA Holder may only transfer this Warrant, in whole or
          in part, to an unaffiliated third party (a) in a widely
          dispersed public offering, (b) to one or more investors,
          in one or more transactions, none of whom, after such
          purchase would hold more than 2% of the voting securities
          of the Company then outstanding assuming that the
          Warrants being transferred to such investor have been
          fully exercised by such investor, (c) to any Person that
          already controls the Company prior to such transfer, (d)

          advance by the Federal Reserve System.

                    10.  Availability of Information.  The Company
          shall timely file the reports required to be filed by it
          under the Securities Act and the Exchange Act (including

          15(d) of the Exchange Act referred to in subparagraph (c)
          of Rule 144 adopted by the Commission under the
          Securities Act) and the rules and regulations adopted by
          the Commission thereunder (or, if the Company is not
          required to file such reports, will, upon the request of
          any holder of Registrable Securities, make publicly
          available other information) and will take such further
          action as any holder of Registrable Securities may
          reasonably request, all to the extent required from time
          to time to enable such holder to sell Registrable
          Securities without registration under the Securities Act
          within the limitation of the exemptions provided by (a)
          Rule 144 under the Securities Act, as such Rule may be
          amended from time to time, or (b) any similar rule or
          regulation hereafter adopted by the Commission.  Upon the
          request of any holder of Registrable Securities, the
          Company will deliver to such holder a written statement
          as to whether it has complied with the requirements of
          this section 10.

                    11.  Reservation of Stock, etc.  The Company
          will at all times reserve and keep available, solely for
          issuance and delivery upon exercise of the Warrants, the
          number of shares of Common Stock (or Other Securities)
          from time to time issuable upon exercise of all Warrants
          at the time outstanding.  All shares of Common Stock (or
          Other Securities) issuable upon exercise of any Warrants
          shall be duly authorized and, when issued upon such
          exercise, shall be validly issued and, in the case of
          shares, fully paid and nonassessable with no liability on
          the part of the holders thereof.

                    12.  Registration and Transfer of Warrants,
          etc.

                    12.1. Warrant Register; Ownership of Warrants. 
          The Company will keep at its principal office a register
          in which the Company will provide for the registration of
          Warrants and the registration of transfers of Warrants. 
          The Company may treat the Person in whose name any
          Warrant is registered on such register as the owner
          thereof for all other purposes, and the Company shall not
          be affected by any notice to the contrary, except that,
          if and when any Warrant is properly assigned in blank,
          the Company may (but shall not be obligated to) treat the
          bearer thereof as the owner of such Warrant for all
          purposes.  Subject to section 9, a Warrant, if properly
          assigned, may be exercised by a new holder without a new
          Warrant first having been issued.

                    12.2.  Transfer and Exchange of Warrants.  Upon
          surrender of any Warrant for registration of transfer or
          for exchange to the Company at its principal office, the
          Company at its expense will (subject to compliance with
          section 9, if applicable) execute and deliver in exchange
          therefor a new Warrant or Warrants of like tenor, in the
          name of such holder or as such holder (upon payment by
          such holder of any applicable transfer taxes) may direct,
          calling in the aggregate on the face or faces thereof for
          the number of shares of Common Stock called for on the
          face or faces of the Warrant or Warrants so surrendered. 

                    12.3.  Replacement of Warrants.  Upon receipt
          of evidence reasonably satisfactory to the Company of the
          loss, theft, destruction or mutilation of any Warrant
          and, in the case of any such loss, theft or destruction
          of any Warrant, upon delivery of an indemnity bond in
          such reasonable amount as the Company may determine or,
          in the case of any such mutilation, upon the surrender of
          such Warrant for cancellation to the Company at its
          principal office, the Company at its expense will execute
          and deliver, in lieu thereof, a new Warrant of like
          tenor.  

                    13.  Registration Rights.  The Purchaser or any
          assignee of this Warrant shall be entitled to all rights
          and benefits regarding the registration of Common Stock
          and Registrable Securities set forth in the Registration
          Rights Agreement.
