                            NEXAR TECHNOLOGIES, INC.

                          Certificate of Incorporation
                          ----------------------------
         These by-laws,  the powers of the  Corporation and of its directors and
stockholders,  and all matters  concerning  the conduct  and  regulation  of the
business  of the  Corporation,  shall be  subject to such  provisions  in regard
thereto as are set forth in the certificate of  incorporation  filed pursuant to
the General  Corporation  Law of  Delaware  which is hereby made a part of these
by-laws.

         The term "certificate of  incorporation"  in these by-laws,  unless the
context  requires  otherwise,  includes  not only the  original  certificate  of
incorporation  filed to  create  the  Corporation  but also all  other  restated
certificates,  amendments,  agreements  of  merger  or  consolidation,  plans of
reorganization,  or other instruments,  howsoever designated,  filed pursuant to
the General  Corporation  Law of  Delaware  which have the effect of amending or
supplementing  in  some  respect  the  Corporation's   original  certificate  of
incorporation.

                                   ARTICLE II.
                                   -----------

                                 Annual Meeting
                                 --------------
   
         The annual meeting of  stockholders  shall be held within six months of
the end of the previous  fiscal year of the  Corporation,  within or without the
State of Delaware,  on the date and at the time fixed, from time to time, by the
directors.  Purposes for which an annual  meeting is to be held,  in addition to
those  prescribed  by law,  by the  certificate  of  incorporation  or by  these
by-laws,  may be  specified  by the  directors  or the  president  and  shall be
included  in the notice of the  meeting.  If the board of  directors  determines
that,  in the  interest of an  informed  stockholder  vote on any matter,  it is
appropriate  to adjourn the annual  meeting of  stockholders  to a later date in
order to make available information materially relevant to consideration of such
matter,  the president or other officer  presiding at such meeting may defer any
action  on  such  matter  and,  without  a  stockholder  vote on the  matter  of
adjournment,  adjourn the meeting for the purpose of  considering  and acting on
such matter at a session to be convened at a later date. When the annual meeting
is adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place  thereof are announced at the meeting at which the
adjournment  is taken.  If the  adjournment  is for more than thirty days, or if
after the adjournment a new record date
    

is fixed for the adjourned  meeting,  a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

                        Special Meetings of Stockholders
                        --------------------------------

         Special  meetings  of the  stockholders  may be held  either  within or
without the State of Delaware,  at such time and place and for such  purposes as
shall be specified  in a call for such  meeting made by the board of  directors,
the Chief  Executive  Officer  or the  President  of the  Corporation  or by the
Secretary  within 10 days after receipt of the written  request of a majority of
the directors.

                        Notice of Stockholders' Meetings
                        --------------------------------

         Whenever stockholders are required or permitted to take any action at a
meeting,  a written  notice of the meeting  shall be given which shall state the
place,  date and hour of the meeting and, in the case of a special meeting,  the
purpose or purposes for which the meeting is called, which notice shall be given
not less than ten nor more  than  sixty  days  before  the date of the  meeting,
except where longer notice is required by law, to each  stockholder  entitled to
vote at such meeting,  by leaving such notice with him or by mailing it, postage
prepaid,  directed to him at his  address as it appears  upon the records of the
Corporation.  In  case of the  death,  absence,  incapacity  or  refusal  of the
secretary,  such  notice  may be  given  by a person  designated  either  by the
secretary  or by the person or persons  calling  the  meeting or by the board of
directors. When a meeting is adjourned to another time or place, notice need not
be given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the  adjournment  is taken.  At the  adjourned  meeting the
Corporation  may transact any business  which might have been  transacted at the
original  meeting.  If the adjournment is for more than thirty days, or if after
the adjournment a new record date is fixed for the adjourned  meeting,  a notice
of the adjourned  meeting shall be given to each  stockholder of record entitled
to vote at the meeting.

         An  affidavit  of the  secretary  or an  assistant  secretary or of the
transfer agent of the  Corporation  that the notice has been given shall, in the
absence of fraud, be prima facie evidence of the facts stated therein.

                    Quorum of Stockholders; Stockholder List
                    ----------------------------------------

         At any meeting of the stockholders, a majority of all shares issued and
outstanding and entitled to vote upon a question to be considered at the meeting
shall  constitute  a quorum  when  represented  at such  meeting by the  holders
thereof  in person or by their  duly  constituted  and  authorized  attorney  or
attorneys, but holders of a lesser interest may adjourn any meeting from time to
time, and the meeting may be held as adjourned  without further  notice.  When a
quorum is present at any meeting, a majority of the stock so represented thereat
and voting on any question  brought before such meeting shall be  determinative,
except  where  a  larger  vote  is  required  by  law,  by  the  certificate  of
incorporation  or by these  by-laws,  and except that the vote  required for the
election of directors shall be as set forth in the certificate of incorporation.

         The secretary or other officer  having charge of the stock ledger shall
prepare and make,  at least ten days before  every  meeting of  stockholders,  a
complete list of the stockholders  entitled to vote at the meeting,  arranged in
alphabetical  order,  and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the  examination  of any  stockholder,  for any purpose  germane to the meeting,
during  ordinary  business  hours for a period of at least ten days prior to the
meeting,  either at a place  within the city or town where the  meeting is to be
held, which place shall have been specified in the notice of the meeting, or, if
not so specified,  at the place where the meeting is to be held. Said list shall
also be produced and kept at the time and place of the meeting  during the whole
time thereof and may be inspected by any stockholder  who is present.  The stock
ledger  shall be the only  evidence as to who are the  stockholders  entitled to
examine the stock ledger,  the list of stockholders  required by this Article or
the books of the Corporation,  or the stockholders entitled to vote in person or
by proxy at any meeting of stockholders.

                                   ARTICLE VI.

                               ------------------

         Except as otherwise provided in the certificate of incorporation,  each
stockholder  shall at every meeting of the  stockholders be entitled to one vote
for each share of the capital stock held by such stockholder. Directors shall be
elected  by a  plurality  of the  votes  of the  shares  present  in  person  or
represented  by proxy at the  meeting and  entitled  to vote on the  election of
directors.  Any other action shall be authorized by a majority of the votes cast
except where the General  Corporation  Law prescribes a different  percentage of
votes  and/or a  different  exercise  of  voting  power,  and  except  as may be
otherwise prescribed by the provisions of the certificate and these bylaws. Each
stockholder  entitled to vote at a meeting of stockholders or to express consent
or  dissent  to  corporate  action in writing  without a meeting  may  authorize
another person or persons to act for him by proxy but



                                        3





(except as  otherwise  expressly  permitted  by law) no proxy  shall be voted or
acted upon after three years from its date,  unless (a) the proxy provides for a
longer  period,  or (b) the proxy states that it is  irrevocable  and is coupled
with an interest  sufficient in law to support an irrevocable power. A proxy may
be made irrevocable  regardless of whether the interest with which it is coupled
is an interest in the stock itself or an interest in the corporation generally.


         Prior  to,  but not  after,  the  consummation  of an offer and sale of
common  stock  of the  Corporation  to the  public  pursuant  to a  registration
statement filed by the Corporation on Form S-1 under the Securities Act of 1933,
as amended (the "1933 Act"),  unless  otherwise  provided in the  certificate of
incorporation,  any action  required  by law to, or which  may,  be taken at any
annual or  special  meeting  of  stockholders  may be taken  without a  meeting,
without prior notice and without a vote, if a consent in writing,  setting forth
the action so taken,  shall be signed by the holders of outstanding stock having
not less than the minimum  number of votes that would be  necessary to authorize
or take such action at a meeting at which all shares  entitled  to vote  therein
were  present and voted.  Prompt  notice of the taking of such action  without a
meeting  by less  than  unanimous  written  consent  shall  be  given  to  those
stockholders who have not consented in writing.

                                  ARTICLE VII.

                            Stockholders' Record Date
                            -------------------------

         In order that the Corporation may determine the  stockholders  entitled
to  notice  of or to vote at any  meeting  of  stockholders  or any  adjournment
thereof, or entitled to express consent to corporate action in writing without a
meeting, or entitled to receive payment of any dividend or other distribution or
allotment  of any rights,  or entitled to exercise  any rights in respect of any
change,  conversion  or exchange of stock or for the purpose of any other lawful
action,  the board of directors may fix, in advance,  a record date, which shall
not be more than sixty nor less than ten days  before the date of such  meeting,
nor more than sixty days prior to any other action.

         If no record date is fixed:

         (1) The record date for determining  stockholders entitled to notice of
or to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next  preceding the day on which the meeting is
held.

         (2) The record date for  determining  stockholders  entitled to express
consent to corporate  action in writing without a meeting,  when no prior action
by the  board of  directors  is  necessary,  shall be the day on which the first
written consent is expressed.


                                        4





         (3) The record date for determining  stockholders for any other purpose
shall be at the close of  business  on the day on which  the board of  directors
adopts the resolution relating thereto.

         A  determination  of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting,
provided, however, that the board of directors may fix a new record date for the
adjourned meeting.

                               -------------------

         Meetings  of the  stockholders  shall  be  presided  over by one of the
following  officers  in the order of  seniority  and if present and acting - the
Chairman of the Board,  if any,  the  Vice-Chairman  of the Board,  if any,  the
President,  a  Vice-President,  or, if none of the  foregoing  is in office  and
present  and  acting,  by a  chairman  to be  chosen  by the  stockholders.  The
Secretary of the corporation,  or in his absence, an Assistant Secretary,  shall
act as secretary of every meeting, but if neither the Secretary nor an Assistant
Secretary  is present the Chairman of the meeting  shall  appoint a secretary of
the meeting.

                                   ----------

         In advance of any meeting of stockholders, the board of directors shall
appoint one or more  inspectors to act at the meeting and make a written  report
thereof.  If  no  inspector  or  alternate  is  able  to  act  at a  meeting  os
stockholders,  the person  presiding  at the meeting  shall  appoint one or more
inspectors  to act at the meeting.  Each  inspector,  before  entering  upon the
discharge of his duties,  shall take and sign an oath  faithfully to execute the
duties of inspector with strict impartiality and according to the best of his or
her ability.

         The inspectors shall:

         (1)    Ascertain the number of shares outstanding and the voting power
                of each;
         (2)    Determine the shares represented at a meeting and the validity 
                of proxies and ballots;
         (3)    Count all votes and ballots;
         (4)    Determine and retain for a reasonable period a record of the 
                disposition of any challenges made to any determination by the 
                inspectors; and
         (5)    Certify their determination of the number of shares represented 
                at the meeting and their count of all votes and ballots.

                               ------------------

         Except  as  otherwise   provided  by  law  or  by  the  certificate  of
incorporation,  the business and affairs of the corporation  shall be managed by
the board of  directors.  Subject to the rights of holders of  preferred  stock,
nominations  for the election of directors may be made by the board of directors
or a  committee  appointed  by the  board  of  directors  or by any  stockholder
entitled  to  vote  in  the  election  of  directors  generally.   However,  any
stockholder  entitled to vote in the election of  directors  may nominate one or
more persons for  election as  directors at a meeting only if written  notice of
such stockholder's intent to make such nomination or nominations has been given,
either by personal  delivery or by United States mail,  postage prepaid,  to the
secretary  of the  corporation  not later  than 90 days prior to the date of any
annual or special meeting.  In the event that the date of such annual or special
meeting was not publicly  announced by the corporation by mail, press release or
otherwise more than 90 days prior to the meeting,  notice by the  stockholder to
be timely must be delivered to the secretary of the  corporation  not later than
the  close  of  business  on the  tenth  day  following  the day on  which  such
announcement of the date of the meeting was communicated to the stockholders.

         Each such  notice  shall set  forth:  (a) the name and  address  of the
stockholder  who intends to make the  nomination and of the person or persons to
be nominated; (b) a representation that the stockholder is a holder of record of
stock of the corporation  entitled to vote at such meeting and intends to appear
in person or by proxy at the meeting to nominate the person or persons specified
in the notice;  (c) a description of all arrangements or understandings  between
the  stockholder  and each nominee and any other person or persons  (naming such
person or persons)  pursuant to which the  nomination or  nominations  are to be
made by the  stockholder;  (d) such other  information  regarding  each  nominee
proposed  by such  stockholder  as would be  required  to be included in a proxy
statement  filed  pursuant to the proxy  rules of the  Securities  and  Exchange
Commission had the nominee been nominated,  or intended to be nominated,  by the
board of  directors;  and (e) the consent of each nominee to serve as a director
of the corporation if so elected.

         The classification of the board of directors, the term of each class of
directors  and the manner of election and removal of  directors  shall be as set
forth in the certificate of incorporation. Each director shall hold office until
his  successor  is elected and  qualified  or until his earlier  resignation  or
removal.  Any  director  may  resign  at any time  upon  written  notice  to the
corporation. No director need be a stockholder.

         The board of directors  may, by resolution  passed by a majority of the
whole board, designate one or more committees,  each committee to consist of one
or more of the directors of the Corporation. The board may designate one or more
directors as alternate  members of any  committee  who may replace any absent or
disqualified  member at any meeting of the  committee  and may define the number
and qualifications which shall constitute a quorum of such committee.  Except as
otherwise  limited by law,  any such  committee,  to the extent  provided in the
resolution appointing such committee,  shall have and may exercise the powers of
the board of  directors  in the  management  of the  business and affairs of the
Corporation,  and may authorize the seal of the Corporation to be affixed to all
papers which may require it. In the absence or disqualification of a member of a
committee,  the  member  or  members  thereof  present  at any  meeting  and not
disqualified  from voting,  whether or not he or they  constitute a quorum,  may
unanimously  appoint  another  member  of the board of  directors  to act at the
meeting in the place of any such absent or disqualified member.

               Meeting of the Board of Directors and of Committees

         Regular  meetings of the board of directors may be held without call or
formal  notice at such places either within or without the State of Delaware and
at such times as the board may by vote from time to time determine.

         Special  meetings  of the board of  directors  may be held at any place
either  within or without  the State of  Delaware at any time when called by the
president,  treasurer, secretary or two or more directors,  reasonable notice of
the time and place thereof being given to each director. A waiver of such notice
in writing,  signed by the person or persons  entitled to said  notice,  whether
before or after the time  stated  therein,  shall be deemed  equivalent  to such
notice.  In any case it shall be deemed  sufficient notice to a director to send
notice by mail at least forty-eight  hours, or to deliver  personally or to send
notice by telegram at least twenty-four hours, before the meeting,  addressed to
him at his usual or last known business or residence address.

         Unless  otherwise  restricted by the certificate of incorporation or by
other  provisions of these by-laws,  (a) any action  required or permitted to be
taken at any meeting of the board of directors or of any  committee  thereof may
be taken without a meeting if all members of the board or of such committee,  as
the case may be,  consent  thereto in writing and such  writing or writings  are
filed with the minutes of proceedings of the board or committee, and (b) members
of the  board of  directors  or of any  committee  designated  by the  board may
participate in a meeting thereof by means of conference telephone or similar

         Except  as  otherwise   expressly   provided  in  the   certificate  of
incorporation  or in these by-laws,  a majority of the total number of directors
at the time in office shall constitute a quorum for the transaction of business,
except when a vacancy or vacancies prevents such majority,  whereupon a majority
of the directors in office shall  constitute a quorum,  but a smaller  number of
directors  may adjourn any meeting  from time to time.  Except as  otherwise  so
expressly  provided,  the vote of a  majority  of the  directors  present at any
meeting at which a quorum is present shall be the act of the board of directors,
provided,  however, that the affirmative vote in good faith of a majority of the
disinterested directors,  even though the disinterested directors shall be fewer
than a quorum,  shall be  sufficient to authorize a contract or  transaction  in
which one or more  directors  have  interest  if the  material  facts as to such
interest  and the  relation  of the  interested  directors  to the  contract  or
transaction have been disclosed or are known to the directors.

         Any  member or members of the Board of  Directors  or of any  committee
designated by the Board,  may participate in a meeting of the Board, or any such
committee,  as the case may be,  by means of  conference  telephone  or  similar
communications  equipment  by means of which all  persons  participating  in the
meeting can hear each other.

the  certificate of  incorporation  or these by-laws,  a written waiver thereof,
signed by the person entitled to notice, whether before or after the time stated
therein,  shall be deemed  equivalent  to  notice.  Attendance  of a person at a
meeting  shall  constitute a waiver of notice of such  meeting,  except when the
person attends a meeting for the express purpose of objecting,  at the beginning
of the meeting,  to the  transaction of any business  because the meeting is not
lawfully  called or convened.  Neither the business to be transacted at, nor the
purpose of, any regular or special  meeting of the  stockholders,  directors  or
members of a committee of directors  need be specified in any written  waiver of
notice unless so required by the certificate of incorporation or the by-laws.

officer before such  certificate is issued,  it may be issued by the Corporation
with the same effect as if he were such officer at the date of issue.

stockholder  who  so  requests,  the  designations,   preferences  and  relative

destroyed  certificate,  or his legal representative,  to give the Corporation a
bond sufficient to indemnify it against any claim that may be made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance  of such new  certificate  in its place and upon  such  other  terms or

                            Restrictions of Transfer
                            ------------------------

         The following  restrictions  are imposed upon the transfer of shares of
the capital stock of the Corporation:

         (a) The Corporation shall have the right to purchase,  or to direct the
transfer  of, the shares of its  capital  stock in the events and subject to the
conditions and at a price fixed as provided below; each holder of shares of such
capital  stock holds his shares  subject to this right and by accepting the same
upon original issue or subsequent  transfer thereof,  the stockholder agrees for
himself, his legal representatives and assigns as follows:

         (b) in the event of any change in the  ownership of any share or shares
of such  capital  stock  (made or  proposed)  or in the  right  to vote  thereon
(whether by the holder's act or by death,  legal  disability,  operation of law,
legal  processes,  order of court, or otherwise,  except by ordinary  proxies or
powers of attorney) the  Corporation has the right to purchase such share or all
or any part of such shares or to require  the same to be sold to a purchaser  or
purchasers  designated by the  Corporation or to follow each such method in part
at a price per share equal to the fair value thereof at the close of business on
the last  business  day  next  preceding  such  event as  determined  by  mutual
agreement or, failing such agreement, by arbitration as provided below.

         (c) In any such  event  the  owner of the  share  or  shares  concerned
therein  (being for the  purposes of these  provisions,  all persons  having any
property interest  therein) shall give notice thereof in detail  satisfactory to
the Corporation. Within ten days after receipt of


                                       12





said owner's notice,  the Corporation shall elect whether or not to exercise its
said rights in respect of said shares and, if it elects to exercise them,  shall
give notice of its election.

         (d) Failing  agreement  between the owner and the Corporation as to the
price per share to be paid, such price shall be the fair value of such shares as
determined  by three  arbitrators,  one  designated  within  five days after the
termination  of said ten-day  period by the  registered  holder of said share or
shares or his legal representatives,  one within said period of five days by the
Corporation and the third within five days after said appointment last occurring
by the two so chosen. Successor arbitrators,  if any shall be required, shall be
appointed, within reasonable time, as nearly as may be in the manner provided as
to the related original  appointment.  No appointment  shall be deemed as having
been  accomplished  unless such  arbitrator  shall have  accepted in writing his
appointment as such within the time limited for his appointment.  Notice of each
appointment  of an  arbitrator  shall be given  promptly to the other parties in
interest.  Said arbitrators shall proceed promptly to determine said fair value.
The  determination of the fair value of said share or shares by agreement of any
two of the arbitrators  shall be conclusive upon all parties  interested in such
shares.  Forthwith upon such determination the arbitrators shall mail or deliver
notice  of  such  determination  to the  owner  (as  above  defined)  and to the
Corporation.

         (e)  Within  ten days  after  agreement  upon said  price or mailing of
notice  of  determination  of  said  price  by  arbitrators  as  provided  below
(whichever shall last occur), the shares specified therein for purchase shall be
transferred  to the  Corporation  or to the purchaser or  purchasers  designated
therein  or in part to each as  indicated  in such  notice of  election  against
payment of said price at the principal office of the Corporation.

         (f) If in any of the said events,  notice therefor having been given as
provided above, the Corporation elects in respect of any such shares or any part
thereof not to exercise  its said rights,  or fails to exercise  them or to give
notice or make payment all as provided  above,  or waives said rights by vote or
in authorized writing, then such contemplated transfer or such change may become
effective as to those shares with respect to which the Corporation elects not to
exercise  its  rights or fails to  exercises  them or to give  notice or to make
payment,  if  consummated  within  thirty days after such  election,  failure or
waiver by the  Corporation,  or within such longer period as the Corporation may
authorize.

         (g) If the  owner's  notice in respect of any of such shares of capital
stock is not  received by the  Corporation  as provided  above,  or if the owner
fails to comply with these provisions in respect of any such shares in any other
regard,  the  Corporation,  at its option and in addition to its other remedies,
may suspend the rights to vote or to receive  dividends on said  shares,  or may
refuse to register on its books any  transfer  of said  shares or  otherwise  to
recognize  any  transfer or change in the  ownership  thereof or in the right to
vote  thereon,  one or more,  until these  provisions  are complied  with to the
satisfaction  of the  Corporation;  and if the  required  owner's  notice is not
received by the Corporation  after written demand by the Corporation it may also
or independently proceed as though a proper


                                       13





owner's  notice has been  received at the  expiration  of ten days after mailing
such demand,  and, if it exercises its rights with respect to said shares or any
of them, the shares specified shall be transferred accordingly.

         (h) In respect of these  provisions  with  respect to the  transfer  of
shares of capital stock, the Corporation may act by its board of directors.  Any
notice or demand under said provisions shall be deemed to have been sufficiently
given if in writing  delivered  by hand or addressed  by mail  postpaid,  to the
Corporation at its principal office or to the owner (as above defined) or to the
holder registered on the books of the Corporation (or his legal  representative)
of the share or shares in question at the address stated in his notice or at his
address appearing on the books of the Corporation.

         (i) Nothing herein  contained shall prevent the pledging of shares,  if
there is neither a transfer  of the legal  title  thereto  nor a transfer on the
books of the Corporation into the name of the pledgee,  but no pledgee or person
claiming  thereunder  shall be entitled to make or cause to be made any transfer
of pledged  shares by sale thereof or otherwise  (including in this  prohibition
transfer on the books of the  Corporation  into the name of the pledgee)  except
upon  compliance  herewith  and any  such  pledge  shall  be  subject  to  those
conditions and restrictions.

         (j)  Anything to the contrary  contained  herein  notwithstanding,  the
following transactions shall be exempt from the provisions of this by-law:

                  (1) A stockholder's  transfer of any or all shares held either
during such  stockholder's  lifetime or on death by will or intestacy to or to a
trust or a custodian for the benefit of such  stockholder or such  stockholder's
immediate family.  "Immediate  family" as used herein shall mean spouse,  lineal
descendant, father, mother, brother, sister, aunt, uncle, niece or nephew.

                  (2)  A   stockholder's   transfer   of  any  or  all  of  such
stockholder's shares to any other stockholder of the Corporation.

                  (3)  A   stockholder's   transfer   of  any  or  all  of  such
stockholder's  shares  to a  person  who,  at the time of such  transfer,  is an
officer or director of the Corporation.

                  (4) A  corporate  stockholder's  transfer of any or all of its
shares  (i)  pursuant  to  and in  accordance  with  the  terms  of any  merger,
consolidation,  reclassification  of shares  or  capital  reorganization  of the
corporate stockholder, or (ii) to any or all of its stockholders.

                  (5) A transfer by a stockholder  which is a limited or general
partnership to any or all of its partners or retired partners.



                                       14




         In any such case, the  transferee,  assignee,  or other recipient shall
receive and hold such stock subject to the provisions of this by-law,  and there
shall be no  further  transfer  of such  stock  except in  accordance  with this
by-law.

         (k) The  restrictions on transfer  contained in this Article XXVI shall
terminate  immediately prior to the time securities of the Corporation are first
offered to the public  pursuant to a  registration  statement  on Form S-1 filed
with,  and declared  effective  by, the United  States  Securities  and Exchange
Commission under the 1933 Act.

                  (1) Notwithstanding  the foregoing  provisions of this Article
XXVI with respect to the  determination of purchase price of shares of stock, in
the event of any  inconsistency  between such  provisions  and those of employee
purchase or other  agreements  between the  Corporation and persons who purchase
shares of its capital stock, those of such employee purchase or other agreements
shall govern.

incorporation,  these by-laws,  as from time to time altered or amended,  may be
