         amendment to such registration statement, including the form of final

                 4.  Offering by Underwriters.  It is understood that the
several Underwriters propose to offer the Securities for sale to the public as
set forth in the Prospectus.

                 5.  Agreements.  The Company agrees with the several
Underwriters that:

                 (a)  The Company will use its best efforts to cause the
         Registration Statement, if not effective at the Execution Time, and
         any amendment thereof, to become effective as promptly as possible.  
         Prior to the termination of the offering of the Securities, the 
         Company will not file any amendment of the Registration Statement or 
         supplement to the Prospectus unless the Company has furnished you a 
         copy for your review prior to filing and will not file any such 
         proposed amendment or supplement to which you reasonably object. 
         Subject to the foregoing sentence, if the Registration Statement has 
         become or becomes effective pursuant to Rule 430A, or filing of the 
         Prospectus is otherwise required under Rule 424(b), the Company will 
         cause the Prospectus, properly completed, and any supplement thereto 
         to be filed with the Commission pursuant to the applicable paragraph 
         of Rule 424(b) within the time period prescribed and will provide 
         evidence satisfactory to the Representatives of such timely filing.  
         The Company will promptly advise the Representatives (i) when the 
         Registration Statement,
   7
                                                                               7


         if not effective at the Execution Time, and any amendment thereto,
         shall have become effective, (ii) when the Prospectus, and any
         supplement thereto, shall have been filed (if required) with the
         Commission pursuant to Rule 424(b), (iii) when, prior to termination
         of the offering of the Securities, any amendment to the Registration
         Statement shall have been filed or become effective, (iv) of any
         request by the Commission for any amendment of the Registration
         Statement or supplement to the Prospectus or for any additional
         information, (v) of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement or the
         institution or threatening of any proceeding for that purpose and (vi)
         of the receipt by the Company of any notification with respect to the
         suspension of the qualification of the Securities for sale in any
         jurisdiction or the initiation or threatening of any proceeding for
         such purpose.  The Company will use its best efforts to prevent the
         issuance of any such stop order and, if issued, to obtain as soon as
         possible the withdrawal thereof.

                 (b)  If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus as then supplemented would include
         any untrue statement of a material fact or omit to state any material
         fact necessary to make the statements therein in the light of the
         circumstances under which they were made not misleading, or if it
         shall be necessary to amend the Registration Statement or supplement
         the Prospectus to comply with the Act or the Exchange Act or the
         respective rules thereunder, the Company promptly will (i) prepare and
         file with the Commission, subject to the second sentence of paragraph
         (a) of this Section 5, an amendment or supplement which will correct
         such statement or omission or effect such compliance and (ii) supply
         any supplemented Prospectus to you in such quantities as you may
         reasonably request.

                 (c)  As soon as practicable, the Company will make generally
         available to its security holders and to the Representatives an
         earnings statement or statements of the Company and its subsidiaries
         which will satisfy the provisions of Section 11(a) of the Act and Rule
         158 under the Act.

                                                                               8


                 (d)  The Company will furnish to the Representatives and
         counsel for the Underwriters, without charge, signed copies of the
         Registration Statement (including exhibits thereto) and to each other
         Underwriter a copy of the Registration Statement (without exhibits
         thereto) and, so long as delivery of a prospectus by an Underwriter or
         dealer may be required by the Act, as many copies of each Preliminary
         Prospectus and the Prospectus and any supplement thereto as the
         Representatives may reasonably request.  The Company will pay the
         expenses of printing or other production of all documents relating to
         the offering.

                 (e)  The Company will arrange for the qualification of the
         Securities for sale under the laws of such jurisdictions as the
         Representatives may reasonably designate, will maintain such 
         qualifications in effect so long as required for the distribution of 
         the Securities, except that the Company shall not be required in
         connection therewith to qualify as a foreign corporation or to 
         execute a general consent to service of process in any state or 
         subject itself to general taxation in connection with such 
         qualification, and will pay the fee of the National Association of 
         Securities Dealers, Inc., in connection with its review of the 
         offering.

               (f)  The Company will not, for a period of 90 days following
         the Execution Time, without the prior written consent of the
         Representatives, offer, sell or contract to sell, or otherwise dispose
         of, directly or indirectly, or announce the offering of, any other
         shares of Common Stock or any securities convertible into, or
         exchangeable for, shares of Common Stock; provided, however, that the
         Company may issue and sell Common Stock pursuant to any employee stock
         option plan, stock purchase plan, stock ownership plan or dividend 
         reinvestment plan of the Company in effect at the Execution Time and 
         the Company may issue Common Stock issuable upon the conversion of 
         securities outstanding at the Execution Time or the exercise of 
         warrants outstanding at the Execution Time or which the Company is
         contractually obligated to issue at the Execution Time.

                 (g)  The Company confirms as of the date hereof that it is in
         compliance with all provisions of Section 1 of Laws of Florida,
         Chapter 92-198,An Act Relating to Disclosure of Doing Business with
         Cuba, and the Company further agrees that if it commences engaging in
         business with the government of Cuba or with any person or affiliate
         located in Cuba after the date the Registration Statement becomes or
         has become effective with the Securities and Exchange Commission or
         with the Florida Department of Banking and Finance (the "Department"),

                      (iii) the Company's authorized equity capitalization is
                 as set forth in the Prospectus; the capital stock of the
                 Company conforms to the description thereof contained in the
                 Prospectus; the outstanding shares of Common Stock have been
                 duly and validly authorized and issued and are fully paid and

                 outstanding shares of capital stock of the Company are not 
                 entitled to preemptive or other rights to subscribe for the 
                 Securities;

                        (iv) to the best knowledge of such counsel, there is no
                 pending or threatened action, suit or proceeding before any

                 a character required to be disclosed in the
   11
                                                                              11


                 Registration Statement which is not adequately disclosed in
                 the Prospectus, and there is no franchise, contract or other
                 document of a character required to be described in the
                 Registration Statement or Prospectus, or to be filed as an
                 exhibit, which is not described or filed as required;
        
                          (v) the Registration Statement has become effective
                 under the Act; any required filing of the Prospectus, and any
                 supplements thereto, pursuant to Rule 424(b) has been made in
                 the manner and within the time period required by Rule 424(b);
                 to the best knowledge of such counsel, no stop order
                 suspending the effectiveness of the Registration Statement has
                 been issued, no proceedings for that purpose have been
                 instituted or threatened and the Registration Statement and
                 the Prospectus (other than the financial statements and other
                 financial and statistical information contained therein as to
                 which such counsel need express no opinion) comply as to form
                 in all material respects with the applicable requirements of
                 the Act and the Exchange Act and the respective rules
                 thereunder; and such counsel has no reason to believe that at
                 the Effective Date the Registration Statement contained any
                 untrue statement of a material fact or omitted to state any
                 material fact required to be stated therein or necessary to
                 make the statements therein not misleading or that the
                 Prospectus includes any untrue statement of a material fact or
                 omits to state a material fact necessary to make the
                 statements therein, in the light of the circumstances under
                 which they were made, not misleading;

                       (vi) this Agreement has been duly authorized, executed 
                 and delivered by the Company;

                      (vii) no consent, approval, authorization or order of any
                 court or governmental agency or body is required for the
                 consummation of the transactions contemplated herein, except
                 such as have been obtained under the Act and such as may be
                 required under the blue sky laws of any jurisdiction in
                 connection with the purchase and distribution of the
                 Securities by the Underwriters;
   12
                                                                              12


                    (viii) neither the issue and sale of the Securities, nor
                 the consummation of any other of the transactions herein
                 contemplated nor the fulfillment of the terms hereof will
                 conflict with, result in a breach or violation of, or
                 constitute a default under any law or the charter or by-laws
                 of the Company or the terms of any indenture or other
                 agreement or instrument known to such counsel and to which the
                 Company, any of its Subsidiaries, General DataComm Ltd. or
                 General DataComm Limited is a party or bound or any
                 judgment, order or decree known to such counsel to be
                 applicable to the Company, any of its Subsidiaries, General
                 DataComm Ltd. or General DataComm Limited of any
                 court, regulatory body, administrative agency, governmental
                 body or arbitrator having jurisdiction over the Company, any
                 of its Subsidiaries, General DataComm Ltd. or General DataComm
                 Limited; and

                        (ix) no holders of securities of the Company have
                 rights to the registration of such securities under the
                 Registration Statement.

         In rendering such opinion, such counsel may rely (A) as to matters
         involving the application of laws of any jurisdiction other than the
         General Corporation Law of the State of Delaware, the laws of the
         State of New York or the laws of the United States, to the extent they
         deem proper and specified in such opinion, upon the opinion of other
         counsel of good standing whom they believe to be reliable and who are
         satisfactory to counsel for the Underwriters and (B) as to matters of
         fact, to the extent they deem proper, on certificates of responsible
         officers of the Company and public officials.  References to the
         Prospectus in this paragraph (b) include any supplements thereto at
         the Closing Date.

                 (c) The Company shall have furnished to the Representatives
         the opinion of (                   ), special Canadian counsel to the
         Company, dated the Closing Date, to the effect that General DataComm  
         Ltd. has been duly incorporated and is validly existing as a
         corporation in good standing under the laws of Canada, with full 
         corporate power and authority to own its properties and conduct its 
         business as described in the Prospectus, and is duly qualified to do 
         business as a foreign corporation and is in good standing under the 
         laws of Canada.

                 (d)  The Company shall have furnished to the Representatives
         the opinion of (            ), special United Kingdom counsel to the
         Company, dated the Closing Date, to the effect that General DataComm
         Limited has been duly incorporated and is validly existing as a

         its business as described in the Prospectus, and is duly qualified to

         Swaine & Moore, counsel for the Underwriters, such opinions and
         letters, dated the Closing Date, with respect to the issuance and sale
         of the Securities, the Registration Statement, the Prospectus
         (together with any supplement thereto) and other related matters as
         the Representatives may reasonably require, and the Company shall have
         furnished to such counsel such
   13
                                                                              13


         documents as they request for the purpose of enabling them to pass
         upon such matters.

                 (f)  The Company shall have furnished to the Representatives a
         certificate of the Company, signed by the Chairman of the Board or the
         President and the principal financial or accounting officer of the
         Company, dated the Closing Date, to the effect that the signers of
         such certificate have carefully examined the Registration Statement,
         the Prospectus, any supplement to the Prospectus and this Agreement
         and that:

                          (i) the representations and warranties of the Company
                 in this Agreement are true and correct in all material
                 respects on and as of the Closing Date with the same effect as
                 if made on the Closing Date and the Company has complied with
                 all the agreements and satisfied all the conditions on its
                 part to be performed or satisfied at or prior to the Closing
                 Date;

                        (ii) no stop order suspending the effectiveness of the
                 Registration Statement has been issued and no proceedings for
                 that purpose have been instituted or, to the Company's
                 knowledge, threatened; and

                      (iii) since the date of the most recent financial
                 statements included in the Prospectus (exclusive of any
                 supplement thereto), there has been no material adverse change
                 in the condition (financial or other), earnings, business or
                 properties of the Company and its subsidiaries on a
                 consolidated basis, whether or not arising from transactions 
                 in the ordinary course of business, except as set forth in or 
                 contemplated in the Prospectus (exclusive of any supplement 
                 thereto).

                 (g)  At the Execution Time and at the Closing Date, Coopers &
         Lybrand shall have furnished to the Representatives a letter or
         letters, dated respectively as of the Execution Time and as of the
         Closing Date, in form and substance satisfactory to the
         Representatives, confirming that they are independent accountants
         within the meaning of the Act and the Exchange Act and the
   14
                                                                              14


         respective applicable published rules and regulations thereunder and
         stating in effect that:

                          (i) in their opinion the audited financial statements
                 and financial statement schedules included or incorporated in
                 the Registration Statement and the Prospectus and reported on
                 by them comply in form in all material respects with the
                 applicable accounting requirements of the Act and the Exchange
                 Act and the related published rules and regulations;

                        (ii) on the basis of a reading of the latest unaudited
                 financial statements made available by the Company and its
                 subsidiaries; carrying out certain specified procedures (but
                 not an examination in accordance with generally accepted
                 auditing standards) which would not necessarily reveal matters
                 of significance with respect to the comments set forth in such
                 letter; a reading of the minutes of the meetings of the
                 stockholders, directors and audit and stock option committees
                 of the Company and the Subsidiaries; and inquiries of certain
                 officials of the Company who have responsibility for financial
                 and accounting matters of the Company and its subsidiaries as
                 to transactions and events subsequent to September 30, 1994,
                 nothing came to their attention which caused them to believe
                 that:

                                  (1) with respect to the period subsequent to
                          September 30, 1994, there were any changes, at a
                          specified date not more than five business days prior
                          to the date of the letter, in the long-term debt,
                          receivables or inventories of the Company and its 
                          subsidiaries or capital stock of the Company 
                          or decreases in the stockholders' equity of 
                          the Company or decreases in cash and cash
                          equivilants, working capital or total assets of the 
                          Company and its subsidiaries as compared with the 
                          amounts shown on the September 30, 1994, consolidated
                          balance sheet included or incorporated in the 
                          Registration Statement and the Prospectus, or for the 
                          period from October 1, 1994, to such specified date 
                          there were any decreases, as compared with the 
                          corresponding period in the preceding
   15
                                                                              15

                          software costs, gross profit, operating income or in
                          total or per share amounts of net income of the
                          Company and its subsidiaries, except in all instances
                          for changes or decreases set forth in such  letter,
                          in which case the letter shall be accompanied by an 
                          explanation by the Company as to the significance
                          thereof unless said  explanation is not deemed
                          necessary by the Representatives; or
        
                                  (2)  the information included or incorporated
                          by reference in the Registration Statement and the
                          Prospectus in response to Regulation S-K, Item 301
                          (Selected Financial Data), Item 302 (Supplementary
                          Financial Information) and Item 402 (Executive
                          Compensation) is not in conformity with the 
                          applicable disclosure requirements of Regulation S-K;
                          and

                      (iii) they have performed certain other specified
                 procedures as a result of which they determined that certain
                 information of an accounting, financial or statistical nature
                 (which is limited to accounting, financial or statistical
                 information derived from the general accounting records of the
                 Company and its subsidiaries) set forth in the Registration
                 Statement and the Prospectus,  including the information set
                 forth under the captions "Prospectus Summary--The Company",
                 "Selected Consolidated Financial Data" and "Management's
                 Discussion and Analysis of Financial Condition and Results of
                 Operations" in the Prospectus, and the information included or
                 incorporated in Items 1, 2, 6, 7, 8, 11 and 13 of the
                 Company's Annual Report on Form 10-K, incorporated in the
                 Registration Statement and the Prospectus, agrees with the
                 accounting records of the Company and its subsidiaries,
                 excluding any questions of legal interpretation.

                 (h)  Subsequent to the Execution Time or, if earlier, the
         dates as of which information is given in the Registration Statement
         (exclusive of any amendment
   16
                                                                              16


         thereof) and the Prospectus (exclusive of any supplement thereto),
         there shall not have been (i) any change or decrease specified in the
         letter or letters referred to in paragraph (g) of this Section 6 or
         (ii) any change, or any development involving a prospective change, in
         or affecting the business or properties of the Company and its
         subsidiaries the effect of which, in any case referred to in clause
         (i) or (ii) above, is, in the judgment of the Representatives, so
         material and adverse as to make it impractical or inadvisable to
         proceed with the offering or delivery of the Securities as
         contemplated by the Registration Statement (exclusive of any amendment
         thereof) and the Prospectus (exclusive of any supplement thereto).

               (i)  At the Execution Time, the Company shall have furnished to
         the Representatives a letter substantially in the form of Exhibit A
         hereto from each executive officer and director of the Company 
         addressed to the Representatives, in which each such person agrees 
         not to offer, sell or contract to sell, or otherwise dispose of, 
         directly or indirectly, or announce an offering of, any shares of 
         Common Stock beneficially owned by such person or any securities 
         convertible into, or exchangeable for, shares of Common Stock for a 
         period of 90 days following the Execution Time without the prior 
         written consent of the Representatives, other than shares of Common 
         Stock disposed of as bona fide gifts; provided that, subsequent to the
         Closing Date, the foregoing shall not apply to the following persons
         to the extent of the number of such shares set forth parenthetically 
         next to such person's name:  Frederick R. Cronin (12,000 shares); 
         James R. Arcara (10,000 shares); William G. Henry (4,000 shares); Rick
         L. Mantz (one-half of the number of shares received upon the exercise
         of options exercisable for up to 50,000 shares); and Eric A. Amster 
         (2,000 shares).

                 (j)  Prior to the Closing Date, the Company shall have
         furnished to the Representatives such further information, certificates
         and documents as the Representatives may reasonably request.

                 If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the Underwriters hereunder
may be canceled at, or at any time prior to, the Closing Date by the
Representatives.  Notice of such cancelation shall be given to the Company in
writing or by telephone or telegraph confirmed in writing.

                                                                              17


                 The documents required to be delivered by this Section 6 shall
be delivered at the office of Cravath, Swaine & Moore, counsel for the
Underwriters, at Worldwide Plaza, 825 Eighth Avenue, New York, New York, on the
Closing Date.

                 7.  Reimbursement of Underwriters' Expenses.  If the sale of
the Securities provided for herein is not consummated because any condition to
the obligations of the Underwriters set forth in Section 6 hereof is not
satisfied, because of any termination pursuant to Section 10 hereof or because
of any refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally upon demand for all out-of-pocket expenses (including reasonable fees
and disbursements of counsel) that shall have been incurred by them in
connection with the proposed purchase and sale of the Securities.

                 8.  Indemnification and Contribution.  (a)  The Company agrees
to indemnify and hold harmless each Underwriter, the directors, officers,
employees and agents of each Underwriter and each person who controls any
Underwriter within the meaning of either the Act or the Exchange Act against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them may become subject under the Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Securities as originally filed or in any amendment thereof,
or in any Preliminary Prospectus or the Prospectus, or in any amendment thereof
or supplement thereto, or arise out of or are based upon the 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 agrees to
reimburse each such indemnified party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that (i) the Company will not be liable in any such case to the extent that any
such loss, claim, damage or liability arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or
   18
                                                                              18


alleged omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any Underwriter through
the Representatives specifically for inclusion therein and (ii) such indemnity
with respect to any Preliminary Prospectus shall not inure to the benefit of
any Underwriter (or any person controlling any Underwriter) from whom the person
asserting any such loss, claim, damage or liability purchased the Securities
which are the subject thereof if such person did not receive a copy of the
Prospectus (or the Prospectus as supplemented), excluding documents
incorporated therein by reference, at or prior to the confirmation of the sale
of such Securities to such person in any case where such delivery is required
by the Act and the untrue statement or omission of a material fact contained in
such Preliminary Prospectus was corrected in the Prospectus (or the Prospectus 
as supplemented) prior to the confirmation of the sale of such Securities to 
such person. This indemnity agreement will be in addition to any liability 
which the Company may otherwise have.

                 (b)  Each Underwriter severally agrees to indemnify and hold
harmless the Company, each of its directors, each of its officers who signs the
Registration Statement, and each person who controls the Company within the
meaning of either the Act or the Exchange Act, to the same extent as the
foregoing indemnity from the Company to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the
Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have.  The Company acknowledges that the
statements set forth in the last paragraph of the cover page and under the
heading "Underwriting" in any Preliminary Prospectus and the Prospectus
constitute the only information furnished in writing by or on behalf of the
several Underwriters for inclusion in any Preliminary Prospectus or the
Prospectus, and you, as the Representatives, confirm that such statements are
correct.

                 (c)  Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying
party under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure
results in the forfeiture by the indemnifying party of substantial rights and
defenses and (ii) will not, in any event, relieve the indemnifying party from
any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above.  The indemnifying party
shall be entitled to appoint counsel of the indemnifying party's choice at the
indemnifying party's expense to represent the indemnified party in any action
for which indemnification is sought (in which case the indemnifying party shall
not thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified
   19
                                                                              19


party or parties except as set forth below); provided, however, that such
counsel shall be reasonably satisfactory to the indemnified party. 
Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel reasonably satisfactory to
the indemnified party to represent the indemnified party within a reasonable
time after notice of the institution of such action or (iv) the indemnifying
party shall authorize the indemnified party to employ separate counsel at the
expense of the indemnifying party.  An indemnifying party will not, without the
prior written consent of the indemnified parties, settle or compromise or
consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified parties
are actual or potential parties to such claim or action) unless such
settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action, suit or
proceeding.

                 (d)  In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is appropriate to reflect
the relative benefits received by the Company and by the Underwriters from the
offering of the Securities; provided, however, that in no case shall any
Underwriter (except as may be provided in any agreement
   20
                                                                              20


among underwriters relating to the offering of the Securities) be responsible
for any amount in excess of the underwriting discount or commission applicable
to the Securities purchased by such Underwriter hereunder.  If the allocation
provided by the immediately preceding sentence is unavailable for any reason,
the Company and the Underwriters shall contribute in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and of the Underwriters in connection with the statements
or omissions which resulted in such Losses as well as any other relevant
equitable considerations.  Benefits received by the Company shall be deemed to
be equal to the total net proceeds from the offering (before deducting
expenses), and benefits received by the Underwriters shall be deemed to be
equal to the total underwriting discounts and commissions, in each case as set
forth on the cover page of the Prospectus.  Relative fault shall be determined
by reference to whether any alleged untrue statement or omission relates to
information provided by the Company or the Underwriters.  The Company and the
Underwriters agree that it would not be just and equitable if contribution were
determined by pro rata allocation or any other method of allocation which does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  For purposes of this Section 8, each person who
controls an Underwriter within the meaning of either the Act or the Exchange
Act and each director, officer, employee and agent of an Underwriter shall have
the same rights to contribution as such Underwriter, and each person who
controls the Company within the meaning of either the Act or the Exchange Act,
each officer of the Company who shall have signed the Registration Statement
and each director of the Company shall have the same rights to contribution as
the Company, subject in each case to the applicable terms and conditions of
this paragraph (d).

                 9.  Default by an Underwriter.  If any one or more
Underwriters shall fail to purchase and pay for any of the Securities agreed to
be purchased by such Underwriter or Underwriters hereunder and such failure to
purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Underwriters shall be obligated
severally to take up and pay for (in the respective proportions which the
amount of Securities set
   21
                                                                              21


forth opposite their names in Schedule I hereto bears to the aggregate amount
of Securities set forth opposite the names of all the remaining Underwriters)
the Securities which the defaulting Underwriter or Underwriters agreed but
failed to purchase; provided, however, that in the event that the aggregate
amount of Securities which the defaulting Underwriter or Underwriters agreed
but failed to purchase shall exceed 10% of the aggregate amount of Securities
set forth in Schedule I hereto, the remaining Underwriters shall have the right
to purchase all, but shall not be under any obligation to purchase any, of the
Securities, and if such nondefaulting Underwriters do not purchase all the
Securities, this Agreement will terminate without liability to any
nondefaulting Underwriter or the Company.  In the event of a default by any
Underwriter as set forth in this Section 9, the Closing Date shall be postponed
for such period, not exceeding seven days, as the Representatives shall
determine in order that the required changes in the Registration Statement and
the Prospectus or in any other documents or arrangements may be effected.
Nothing contained in this Agreement shall relieve any defaulting Underwriter of
its liability, if any, to the Company and any nondefaulting Underwriter for
damages occasioned by its default hereunder.

                 10.  Termination.  This Agreement shall be subject to
termination in the absolute discretion of the Representatives, by notice given
to the Company prior to delivery of and payment for the Securities, if prior to
such time (i) trading in the Company's Common Stock shall have been suspended
by the Commission or the New York Stock Exchange or trading in securities
generally on such Exchange shall have been suspended or limited or minimum
prices shall have been established on such Exchange, (ii) a banking moratorium
shall have been declared either by Federal or New York State authorities or
(iii) there shall have occurred any outbreak or escalation of hostilities,
declaration by the United States of a national emergency or war or other
calamity or crisis the effect of which on financial markets is such as to make
it, in the judgment of the Representatives, impracticable or inadvisable to
proceed with the offering or delivery of the Securities as contemplated by the
Prospectus (exclusive of any supplement thereto).

                 11.  Representations and Indemnities to Survive. The
respective agreements, representations, warranties, indemnities and other
statements of the Company or its officers and of the Underwriters set forth in
or made pursuant to this Agreement will remain in full force and
   22
                                                                              22


effect, regardless of any investigation made by or on behalf of any Underwriter
or the Company or any of the officers, directors or controlling persons
referred to in Section 8 hereof, and will survive delivery of and payment for
the Securities.  The provisions of Sections 7 and 8 hereof shall survive the
termination or cancelation of this Agreement.

                 12.  Notices.  All communications hereunder will be in writing
and effective only on receipt, and, if sent to the Representatives, will be
mailed, delivered or telegraphed and confirmed to them care of Salomon Brothers
Inc, Seven World Trade Center, New York, New York, 10048; or, if sent to the
Company, will be mailed, delivered or telegraphed and confirmed to it at 1579

President-Finance, with a copy to Howard S. Modlin, Weisman, Celler, Spett &
Modlin, 445 Park Avenue, New York, New York 10022.

                 13.  Successors.  This Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 8 hereof,
and no other person will have any right or obligation hereunder.

                 14.  Applicable Law.  This Agreement will be governed by and
construed in accordance with the laws of the State of New York.

Salomon Brothers Inc

As Representatives of the several Underwriters
In Care of Salomon Brothers Inc
Seven World Trade Center
New York, New York 10048

Dear Sirs:

                 This letter is being delivered to you in connection with the
proposed Underwriting Agreement dated             , 1994 (the "Underwriting 
Agreement"), between General DataComm Industries, Inc., a Delaware corporation 
(the "Company"), and you as representatives of a group of Underwriters named 
therein, relating to an underwritten public offering of 1,800,000 shares of 
Common Stock, $0.10 par value (the "Common Stock"), of the Company.

                 In order to induce you and the other Underwriters to enter
into the Underwriting Agreement, the undersigned agrees not to offer, sell or
contract to sell, or otherwise dispose of, directly or indirectly, or announce
an offering of, any shares of Common Stock beneficially owned by the
undersigned or any securities convertible into, or exchangeable for, shares of
Common Stock for a period of 90 days following the day on which the
Underwriting Agreement is executed without your prior written consent, other
than shares of Common Stock disposed of as bona fide gifts.

                 If for any reason the Underwriting Agreement shall be
terminated prior to the Closing Date (as defined in the Underwriting
Agreement), the agreement set forth above shall likewise be terminated.

                                                   Yours very truly,
 
                                        (Signature of executive officer or
                                        director)
 
                                        (Name and address of executive officer 
                                        or director)
