                      PORTA SYSTEMS CORP. AND SUBSIDIARIES
              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Management's  Responsibility For Interim Financial  Statements Including
        All Adjustments Necessary For Fair Presentation

      Management  acknowledges  its  responsibility  for the  preparation of the
accompanying  interim  consolidated   financial  statements  which  reflect  all
adjustments, consisting of normal recurring adjustments, considered necessary in
its opinion for a fair statement of its consolidated  financial position and the
results of its operations for the interim period presented.  These  consolidated
financial  statements  should  be  read  in  conjunction  with  the  summary  of
significant  accounting policies and notes to consolidated  financial statements
included in the Company's  Form 10-K annual  report for the year ended  December
31, 2000.  The audit opinion  included in the December 31, 2000 Form 10-K annual
report  contained an explanatory  paragraph  regarding the Company's  ability to
continue as a going concern.  Results for the interim period are not necessarily
indicative of results for the year.

Note 2: Inventories

      Inventories  are stated at the lower of cost (on the average or  first-in,
first-out  methods) or market.  The composition of inventories at the end of the
respective periods is as follows:

                                       ======            ======

Note 3: Senior Debt

      On  March  31,  2001,   the  Company's  debt  to  its  senior  lender  was
$20,346,000. During the three months then ended, the Company repaid principal of
$400,000.  The current  agreement with the senior lender expires on July 3, 2001
and, accordingly,  the senior debt has been classified as a current liability at
March 31, 2001.

      The Company's borrowings exceed the maximum borrowings under the borrowing
base  formula.  In March 2001,  the senior lender agreed to allow the Company to
defer the  repayment of  borrowings  in excess of the maximum under the formula,
defer all monthly  facility fees and the April 1, 2001 principal  payment to the
earlier of the  termination  of the agreement on July 3, 2001 or the sale of one
or more of the  divisions of the  Company.  The  agreement  also  precluded  the
Company from making any payments on indebtedness to any subordinated  creditors,
although  it permits  payment of  accounts  payable  in the  ordinary  course of
business.

      In April 2001, the Company and its senior lender agreed to add all current
and future interest due, which will be computed at 14%, to the principal balance
through the July 2, 2001.  As  consideration,  the Company  agreed to reduce the
exercise price of the  outstanding  warrants to purchase  approximately  570,000
shares of common stock held by its senior lender to $0.25 per share.


                                  Page 5 of 11


      Financial  debt  covenants  include an interest  coverage  ratio  measured
quarterly, limitations on the incurrence of indebtedness, limitations on capital
expenditures, and prohibitions on declarations of any cash or stock dividends or
the repurchase of the Company's stock. As of March 31, 2001, the Company was not
in compliance with the interest  coverage  covenant.  The Company has obtained a
waiver of such  non-compliance  from its senior  lender  related to the interest
coverage ratio and the over advance under the line through July 2, 2001.

Note 4: Subordinated Notes

      As  of  March  31,  2001,  the  Company  has  outstanding   $6,144,000  of
subordinated  notes, of which $900,000 was due on January 2, 2001 and $5,244,000
becomes due on July 2, 2001. Pursuant to the Company's agreement with its senior
lender,  the Company is  prohibited  from paying  principal  and interest on the
subordinated notes.

Note 5: Segment Data

      The Company has three reportable segments:  Line Connection and Protection
Equipment  ("Line")  whose  products  interconnect  copper  telephone  lines  to
switching  equipment and provides fuse elements that protect telephone equipment
and personnel from electrical  surges;  Operating  Support Systems ("OSS") whose
products automate the testing,  provisioning,  maintenance and administration of
communication  networks and the  management of support  personnel and equipment;
and Signal Processing  ("Signal") whose products are used in data  communication
devices that employ high frequency transformer technology.

      The factors used to determine the above segments focused  primarily on the
types of products and services provided,  and the type of customer served.  Each
of these  segments  is  managed  separately  from  the  others,  and  management
evaluates segment performance based on operating income.

      There has been no  significant  change from December 31, 2000 in the basis
of measurement of segment revenues and profit or loss, and no significant change
in the Company's assets.

Results of Operations

      The Company's  sales for the quarter ended March 31, 2001 were  $7,042,000
representing a decrease of $8,886,000  (56%) compared to the quarter ended March
31, 2000 of $15,928,000.  The overall decrease in sales reflects decreased sales
of OSS  and  Line  equipment.  Signal  sales  increased  by  $74,000  (5%)  from
$1,578,000 to $1,652,000 for the 2000 and 2001 quarters, respectively.

      Line equipment sales decreased by $2,246,000 (37%) from $6,094,000 for the
March 2000 quarter to $3,848,000 for the March 2001 quarter. The decline in line
equipment  sales  reflected  a  significant  decline  in sales to one  customer,
Telmex,  which was not offset by major orders from any other  customers.  During
the March 2000 quarter, we sold approximately $2.7 million of product to Telmex,
whereas our sales to Telmex in the March 2001 quarter were not significant.

      OSS sales  decreased by $6,749,000  (83%) from  $8,114,000 for the quarter
ended March 31, 2000 to  $1,365,000  for the quarter  ended March 31, 2001.  The
decreased  sales  resulted  from lower  shipments to Fujitsu  Telecommunications
Europe  Limited which  provided  approximately  $5,900,000 of sales in the March
2000 quarter.

      Gross  margin for the March 2001  quarter was 20%  compared to 36% for the
March  2000  quarter.  This  decline  in gross  margin  is  attributable  to the
decreased  level of sales.  Because of the low volume of sales,  the Company was
unable to absorb certain fixed expenses associated with the OSS contracts.

      Selling,  general and administrative  expenses decreased by $557,000 (18%)
from  $3,135,000  in the March  2000  quarter  to  $2,578,000  in the March 2001
quarter.  This decrease relates primarily to the Company's efforts to reorganize
its sales and marketing efforts of its OSS division.

      Research  and  development  expenses  decreased  by  $221,000  (16%)  from
$1,408,000  in the March 2000 quarter to  $1,187,000  in the March 2001 quarter.
This decrease in research and  development  expenses  results from the Company's
efforts to reduce its expenses, primarily related to the OSS business.

      As a  result  of the  foregoing,  the  Company  had an  operating  loss of
$2,351,000  for the March 2001  quarter,  as  compared  to  operating  income of
$1,173,000 for the March 2000 quarter.

      Interest  expense  increased  by  $69,000  (7%) from  $934,000  in 2000 to
$1,003,000 in 2001. This change is attributable primarily to increased levels of
borrowing from the senior lender.

         As the result of the  foregoing,  the  Company  generated a net loss of
$3,233,000,  $0.33 per share  (basic and  diluted),  for the March 2001  quarter
versus net income of  $306,000,  $0.03 per share  (basic and  diluted),  for the
March 2000 quarter.

Liquidity and Capital Resources

      At March 31, 2001,  the Company had cash and cash  equivalents of $397,000
compared with  $2,366,000 at December 31, 2000.  The Company's  working  capital
deficit at March 31, 2001 was $26,758,000, compared to a working capital deficit
of  $24,152,000 at December 31, 2000. The reduced level of cash on hand resulted
in the increase in the working capital deficiency. During the March 2001 quarter
of, the net cash used by the Company in operations was $1,557,000.

      As of  March  31,  2001,  the  Company  has  senior  debt  of  $20,346,000
outstanding.  The current  agreement  with the senior lender  expires on July 3,
2001 and,  accordingly,  has been classified as a current liability at March 31,
2001. The Company's borrowings exceed the maximum borrowings under the borrowing
base  formula.  In March 2001,  the senior lender agreed to allow the Company to
defer the  repayment of  borrowings  in excess of the maximum under the formula,
defer all monthly  facility fees and the April 1, 2001 principal  payment to the
earlier of the  termination  of the agreement on July 3, 2001 or the sale of one
or more of the divisions of the Company.  The senior  lender  prohibited us from
making any payments on indebtedness to any subordinated  creditors except to pay
accounts payable in the ordinary course of business.  In April 2001, the Company
and its senior lender agreed to add all current and future  interest due,  which
will be computed at 14%,  to the  principal  balance  through  July 2, 2001.  In
addition,  we were not in  compliance  with the interest  coverage  covenant and
borrowing  base  coverage  under the  agreement  and  obtained a waiver from our
senior lender through July 2, 2001.

      As of March 31, 2001, we had outstanding $6,144,000 of subordinated notes,
of which  $900,000  became due on January 2, 2001 and the balance of  $5,244,000
becomes due on July 2, 2001.  We did not have the  resources to pay the $900,000
of subordinated debt on January 2, 2001 and  approximately  $440,000 of interest
which was due on January 2, 2001.  We have an agreement  in  principle  with the
holders  of  a  majority  of  the  outstanding   subordinated   notes  or  their
representatives  with respect to an extension of the maturity date of the notes.
The agreement in principle is subject to the execution of a definitive agreement
with  the  holders  of  the  subordinated   debt.  The  agreement  in  principle
contemplates  an extension  of the maturity  date of the notes to June 30, 2002,
subject to earlier  prepayment if we sell one or more divisions,  an increase in
the interest rate to 17.5% per annum,  a reduction in the exercise  price of the
warrants  held by the  noteholders  to $.25 per  share,  and the  ability of the
noteholders  to convert the notes and accrued  interest  into common stock after
December  31,  2001 at $.25 per  share  unless  we have  called  the  notes  for
redemption.  In addition,  the holders of the  subordinated  notes will have the
right to elect one director of our board.  We cannot  assure you that we will be
able to negotiate a definitive agreement with the noteholders.

      Our cash  availability  during  2001 and  thereafter  may be affected by a
number of factors.  At March 31, 2001, we had no cash available under our credit
facility  and we had  borrowed  more than the amount  available  to us under our
borrowing  base.  To the  extent  that  credit  is not  available,  we may  have
difficulty performing our obligations under our contracts, which could result in
the  cancellation  of  contracts  or the loss of future  business.  In addition,
$1,160,000  of senior  debt and  $900,000  of  subordinated  debt  became due in
January 2001 and $24,830,000 of senior and subordinated  debt will become due in
July 2001. As noted above, we have an agreement in principle with the holders of
a majority of the outstanding  subordinated notes or their  representatives with
respect to an  extension  of the maturity  date of the notes.  The  agreement in
principle is subject to the execution of a definitive agreement with the holders
of the subordinated  debt. We are continuing to negotiate with our senior lender
with  respect to an  extension  beyond the July 3, 2001  maturity of our current
facility.  However, we do not presently have the ability to pay these debts and,
if  we  cannot  finalize  a  definitive   agreement  with  the  holders  of  the
subordinated debt, obtain either an extension on the maturity of our senior debt
or an  alternative  financing  source or raise funds from the sale of one of our
divisions, we may be unable to meet these financial obligations.

      We are  addressing  our  need for  liquidity  by  seeking  to  extend  our
agreement  with our senior  lender,  finalize a  definitive  agreement  with the
holders  of the  subordinated  debt,  and sell of one or more of our  divisions.
Although we have been engaged in negotiations with respect to the sale of one of
our divisions,  these negotiations were terminated without our entering into any
agreement.  Although we are  continuing  to explore the possible  sale of one or
more of our divisions,  we cannot assure you that we will be successful in these
efforts.  Because of our present stock price, it is highly unlikely that we will
be able to raise  funds  through  the sales of our  equity  securities,  and our
financial condition prevents us from issuing debt securities.  In the event that
we are  unable  to  extend  our  debt  obligations  and  sell one or more of our
divisions, we cannot assure you that we will be able to continue in operations.
