BROOKTROUT TECHNOLOGY, INC.

Notes to Unaudited Condensed Consolidated Financial Statements


1.       Basis of Presentation

          The accompanying unaudited condensed consolidated financial statements
have been prepared by the Company pursuant to the rules and regulations of the
Securities and Exchange Commission regarding interim financial reporting. They
should be read in conjunction with the audited consolidated financial statements
incorporated by reference in or included in the Company's 1997 Annual Report on
Form 10K.

         In the opinion of management, the accompanying unaudited condensed
consolidated financial statements have been prepared on the same basis as the
audited consolidated financial statements and include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the interim periods presented.

         The operating results for the interim periods presented are not
necessarily indicative of the results which could be expected for the full year.


2.       Acquisition

         On June 30, 1997, the Company acquired the assets and assumed certain
liabilities of Netaccess, Inc., a worldwide supplier of Primary Rate ISDN
network interface products and multiport modem products for open,
standards-based remote access and computer telephony systems. The purchase price
was $9.9 million, paid in cash, and the Company agreed to assume certain
liabilities aggregating $2 million. The acquisition was accounted for as a
purchase, and accordingly, the results of operations of Netaccess, Inc. were
included in the Company's consolidated financial statements from the date of
acquisition. The purchase price was allocated to the assets acquired based upon
their fair values using independent appraisals.

3.       Income Per Share

         Basic income per share is computed using the weighted average number of
common shares outstanding during each period. Diluted income per common share
reflects the effect of the Company's outstanding options (using the treasury
stock method), except where such options would be antidilutive. A reconciliation
of shares for basic and shares for diluted is as follows:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
         RESULTS OF OPERATIONS.

RESULTS OF OPERATIONS

Three Months Ended June 30, 1998 and 1997

         Revenue during the three months ended June 30, 1998 increased by
approximately 77% to $26,104,000, up from $14,725,000 during the three months
ended June 30, 1997. This growth was partially attributable to increased
shipments of TR Series products. Increased sales from the TR Series products
reflect the growth in the local area network/fax market segment served by the
Company. In 1998, revenue increased due to the inclusion of sales of Primary
Rate ISDN telephone network interface products acquired through the acquisition
of Netaccess, Inc. on June 30, 1997.

         Cost of product sold was $10,915,000, or 42% of revenue, during the
three months ended June 30, 1998, compared to $6,543,000, or 44% of revenue, for
the same period in 1997. Gross profit percentage was approximately 58% and 56%
for the three months ended June 30, 1998 and 1997, respectively. The increase in
gross profit percentage is the result of cost reduction efforts on the TR Series
products partially offset by product mix caused by an increased proportion of
lower margin network interface cards.

         Research and development expense was $5,380,000, or 21% of revenue,
compared with $2,924,000, or 20% of revenue, for the three months ended June 30,
1998 and 1997, respectively. The increase reflects the Company's development
efforts for the next generation of Netaccess products and for continued
development of the TR Series product family, computer telephony software
development tools, Brooktrout Open Systems Telephony Architecture (BOSTon),
Interspeed, Inc. , as well as fax and OEM systems development. The Company
intends to continue to commit significant resources to product development.

         Selling, general and administrative expense was $7,221,000 during the
three months ended June 30, 1998, compared with $4,448,000 during the same
period in 1997. This higher expense level resulted from increased staffing,
promotional activities and depreciation expense. As a percentage of revenue,
selling, general and administrative expense for the second quarter of 1998 was
28% of revenue, compared with 30% for the second quarter of 1997.

         During the three months ended June 30, 1997, the Company recorded a
charge of $3,746,000 reflecting the portion of the purchase price for Netaccess,
Inc. allocated to research efforts in-process.

         For the three months ended June 30, 1998, interest and other income was
$568,000, compared with $480,000 for the same period in 1997.

         The Company's effective tax rate was 37% in 1998 and 40% in 1997, based
on the Company's estimated effective tax rate for the full year.

Six Months Ended June 30, 1998 and 1997


         Revenue during the six months ended June 30, 1998 increased by
approximately 69% to $50,280,000, up from $29,795,000 during the six months
ended June 30, 1997. This growth was partially attributable to increased
shipments of TR Series products. Increased sales from the TR Series products
reflect the growth in the local area network/fax market segment served by the
Company. In 1998, revenue increased due to the inclusion of sales of Primary
Rate ISDN telephone network interface products acquired through the acquisition
of Netaccess, Inc. on June 30, 1997.

         Cost of product sold was $20,900,000, or 42% of revenue, during the six
months ended June 30, 1998, compared to $13,065,000, or 44% of revenue, for the
same period in 1997. Gross profit percentage was approximately 58% and 56% for
the six months ended June 30, 1998 and 1997, respectively. The increase in gross
profit percentage is the result of cost reduction efforts on the TR Series
products partially offset by product mix caused by an increased proportion of
lower margin network interface cards.

         Research and development expense was $10,670,000, or 21% of revenue,
compared with $5,290,000, or 18% of revenue, for the six months ended June 30,
1998 and 1997, respectively. The increase reflects the Company's development
efforts for the next generation of Netaccess products and for continued
development of the TR Series product family, computer telephony software
development tools, Brooktrout Open Systems Telephony Architecture (BOSTon),
Interspeed, Inc., as well as fax and OEM systems development.

         Selling, general and administrative expense was $13,853,000 during the
six months ended June 30, 1998, compared with $8,513,000 during the same period
in 1997. This higher expense level resulted from increased staffing, promotional
activities and depreciation expense. As a percentage of revenue, selling,
general and administrative expense for the first six months of 1998 was 28% of
revenue, compared with 29% for the first six months of 1997.

         During the six months ended June 30, 1997, the Company recorded a
charge of $3,746,000 reflecting the portion of the purchase price for Netaccess,
Inc. allocated to research efforts in-process.

         For the six months ended June 30, 1998, interest and other income was
$1,018,000, compared with $922,000 for the same period in 1997.

         The Company's effective tax rate, adjusted for significant permanent or
other differences, was 37% and 17% for the six months ended June 30, 1998
and 1997, respectively. The relatively low tax rate for the six months ended 
June 30, 1997 is primarily due to the nominal amount of pre-tax income reported.
As a result, small changes in tax provisions or benefits booked have an
unusually large effect on the tax rate.

Liquidity and Capital Resources

         For the six months ended June 30, 1998, the Company funded its
operations principally through operating revenue. The Company's working capital
increased from $43.4 million at December 31, 1997 to $44.9 million at June 30,
1998. The increase was attributable primarily to higher cash balances and
investments due to continued profitable operations and were partially offset by
higher accounts payable and other accrual balances.

         In August 1998, the Company renewed its working capital line of credit.
Under the renewed line of credit, the Company may borrow up to $10,000,000 on an
unsecured basis, all of which may be used for issuance of letters of credit,
subject to compliance with certain covenants. The line of credit will expire in
July 1999 and at that time any outstanding balances would be payable in full.
Any amounts borrowed under the line would be subject to interest at the bank's
prime rate. At June 30, 1998 there were no commitments outstanding on letters of
credit; no borrowings have been made during any period presented.

         During the first six months of 1998, the Company invested approximately
$2.6 million in capital equipment. The Company currently has no material
commitments for additional capital expenditures.

         The Company anticipates that cash flows from operations, together with
current cash and marketable securities balances and funds available under the
Company's line of credit, will be sufficient to meet the Company's working
capital and capital equipment expenditure requirements for the foreseeable
future.

Recent Accounting Pronouncements

         Effective January 1, 1998, the Company adopted the provisions of
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" and AICPA Statement of Position No. 97-2, "Software Revenue
Recognition." Adoption of these pronouncements did not have a material effect on
reported results of operations or financial position.

         Effective January 1, 1998, the Company adopted the provisions of
Statement of Financial Accounting Standards No. 131, "Disclosures about Segments
of an Enterprise and Related Information." As allowed by that pronouncement, the
Company will provide information about its operating segments in the annual
financial statements, and will begin providing such information on an interim
basis for the first quarter of 1999.

Item 1.           Legal Proceedings

         Dismissal of Patent Infringement Lawsuit against the Company

         On October 4, 1996, Syntellect Technology Corp. ("Syntellect") filed a
Complaint against the Company in the United States District Court for the
Northern District of Texas (the "Court"), alleging infringement of certain
patents held by Syntellect relating to certain aspects of "automated attendant"
technology (the "Complaint"). Syntellect's Complaint did not identify the
products of the Company which allegedly infringe Syntellect's patents. The
Complaint sought injunctive relief, damages in an unspecified amount, and
multiple damages on account of alleged willful infringement. In December 1996,
the Company filed a Motion to Dismiss the Complaint, which was denied in July
1997. In October 1997, the Company filed a Motion for Summary Judgement which
was granted by the Court on May 10, 1998. On June 10, 1998, the period for
Syntellect to appeal the dismissal of its Complaint expired. The Company is
unaware of whether Syntellect plans to pursue this litigation further.
