SENIOR CREDIT FACILITY AMENDMENT

      In November 1997, in conjunction with the Recapitalization of our
Company, the Company entered into an Assumption Agreement and Amended and
Restated Credit Agreement with CIBC and First Union and other lenders, pursuant
to which the Company could borrow up to $125.0 million consisting of a
revolving credit facility of up to $40.0 million (the "Revolving Credit
Facility") and a Senior Term Loan in an aggregate principal amount of $85.0
million (the "Senior Term Loan"). Principal payments on the Senior Term Loan
are due quarterly through maturity, October 1, 2004. The revolving credit
agreement expires on October 1, 2003. Borrowings under this agreement rank
senior to all other indebtedness of the Company and are Secured by all the
assets of the Company.


 	In October 1999 the Amended and Restated Credit Agreement (the "Credit
Agreement") was amended to increase the Revolving Credit Facility to $70.0
million, increase to $4.0 million the allowable amount of annual lease
commitments, increase to $0.25 million the amount of permitted loans to Officers
and employees, increase to $50.0 million the permitted annual amount of
pre-approved acquisitions, and change the step-down schedule of borrowing
availability. The Revolving Credit commitments shall automatically be
permanently reduced according to the following schedule, commencing on
January 1, 2002, by the amount set forth opposite each date.

ITEM 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (UNAUDITED)

Overview

     We recognize net revenues from the sale of advertising placed in
each directory when the completed directory is distributed. Costs directly
related to sales, production, printing and distribution of each directory are
capitalized as deferred directory costs and then matched against related net
revenues upon distribution. All of our other operating costs are recognized
during the period when incurred. As we continue to acquire or produce more
directories, we adjust the publication schedule periodically to accommodate new
books. In addition, changes in distribution dates are affected by market and
competitive conditions and the staffing level required to achieve the
individual directory revenue goals. As a result, we may publish the directories
in periods different than the previous year and related revenues may be
recognized in different fiscal quarters from one year to the next. Year to year
results depend on both timing and performance factors.

    Notwithstanding significant monthly fluctuation in net revenues recognized
based on actual distribution dates of individual directories, our bookings and
cash collection activities generally occur at a steady pace throughout the
year. As demonstrated in the following table, our quarterly bookings,
collection of advance payments and total cash receipts vary less than our net
revenues or EBITDA (in millions):

(a) "EBITDA" is defined as net income plus interest expense, discretionary
    contributions to the Company's Equity Compensation Plan (such contributions
    represent special distributions to the Company's Equity Compensation Plan
    in connection with refinancing transactions) and depreciation and
    amortization and is consistent with the definition of EBITDA in the
    indenture relating to our 9 5/8% Senior Subordinated notes and in our
    senior credit facility. EBITDA is not a measure of performance under
    generally accepted accounting principles (GAAP). EBITDA should not be
    considered in isolation or as a substitute for net income, cash flows from
    operating activities and other income or cash flow statement data prepared
    in accordance with GAAP, or as a measure of profitability or liquidity.
    However, management has included EBITDA because it may be used by certain
    investors to analyze and compare companies on the basis of operating
    performance, leverage and liquidity and to determine a company's ability
    to service debt. Our definition of EBITDA may not be comparable to that of
    other companies.

(b) "Bookings" is defined as the daily advertising orders received from
    accounts during a given period and generally occur at a steady pace
    throughout the year.

(c) "Total Cash Receipts" includes both advance payments and collections of
    accounts receivable.

(a)  For a definition of "EBITDA" see the immediately preceding section.

(b)  "EBITDA Margin" is defined as EBITDA as a percentage of net revenues.
     Management believes that EBITDA margin also provides a valuable indication
     of the Company's ability to generate cash flows available for debt
     service.

THREE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THE THREE MONTHS ENDED
     SEPTEMBER 30, 1998

     Net revenues increased $9.2 million, or 31.9%, from $29.0 million in the
three months ended September 30, 1998 to $38.2 million in the same period in
1999. We published 48 directories in the three months ended September 30, 1999
compared to 37 in the same period in 1998. The net revenue growth of $9.2
million was due to $7.6 million from twelve new directories, $8.1 million from
eleven directories for which the publication date moved into the period and
growth in the same 25 directories published during both periods of $1.5
million; offset by $8.0 million of net revenues associated with twelve
directories published in the three months ended September 30, 1998 but not in
the same period in 1999.

     As a result of a combination of factors, including the addition of new
customers, price increases, increases in the amount of advertising by current
customers and new directory features such as colorization of ads, additional
ad sizes and additional headings, our same book revenue growth for the 25
directories published in both periods was 7.2%.

<PAGE>   13

     Cost of revenues increased $1.6 million, or 30.1%, from $5.6 million in
the three months ended September 30, 1998 to $7.2 million in the same period
in 1999. The increase was the result of $1.6 million of costs associated with
twelve new directories published in the three months ended September 30, 1999
and $1.3 million in costs associated with eleven directories published in the
three months ended September 30, 1999, but not in the same period in 1998;
offset by $1.2 million of costs associated with twelve directories published
during the three months ended September 30, 1998, but not in the same period in
1999 and $0.3 million in reductions from the same 25 books published in both
periods. Indirect production support costs increased $0.2 million in the three
months ended September 30, 1999 due to the new directories published in the
third quarter of 1999.

     As a result of the above, gross profit increased $7.6 million, or
32.3%, from $23.4 million in the three months ended September 30, 1998 to $31.0
million in the same period in 1999. Gross margin increased from 80.8% in the
three months ended September 30, 1998 to 81.1% in the same period in 1999 as a
result of lower direct costs on directories published in both periods.

     Sales and marketing expenses increased $3.2 million, or 26.4%, from
$12.2 million in the three months ended September 30, 1998 to $15.4 million in
the same period in 1999. The increase was attributable to increases of $0.7
million in sales support costs, $2.4 million in direct sales costs and $0.1
million in the provision for bad debt.

     The increase in sales support costs of $0.7 million was due to sales
offices acquired since the third quarter of 1998. The increase in direct sales
costs of $2.4 million was as follows: $2.0 million of additional costs were for
the twelve new directories, $1.8 million for eleven directories moving into the
period, and $0.3 million of higher costs associated with the 25 same
directories; offset by $1.7 million of costs associated with twelve directories
that published in the three months ended September 30, 1998 but not in the same
period in 1999. Direct sales costs as a percentage of revenue for the same 25
directories published during both periods decreased from 20.0% to 19.8% in the
three months ended September 30, 1998 compared to the same period in 1999. The
increase in the provision for bad debt of $0.1 million was at a lower rate than
the increase in net revenue due to higher recovered revenue from accounts
previously written off and lower provision rates from new directory titles.

     General and administrative expenses increased $4.4 million, or 102.4%,
from $4.4 million for the three months ended September 30, 1998 to $8.8 million
for the same period in 1999. The increase was due to: amortization of acquired
customer base and other intangibles of $3.6 million and an increase in
incentive compensation costs and increases in other professional service costs
totaling $0.8 million.

     As a result of the above factors, income from operations decreased $0.1
million, or 1.7%, from $6.9 million in the three months ended September 30,
1998 to $6.8 million in the same period in 1999. Income from operations as a
percentage of net revenues decreased from 23.8% in the three months ended
September 30, 1998 to 17.7% in the same period in 1999.

     Interest expense increased $1.0 million, or 22.4%, from $4.6 million in
the three months ended September 30, 1998 to $5.6 million in the same period
in 1999 due to higher levels of debt to fund acquisitions. Tax expense incurred
in the third quarter of 1999 of $0.2 million is for state and federal income
tax expense for Target Directories of Michigan Inc., a wholly owned subsidiary
of TransWestern Publishing Company, LLC.

     As a result of the above factors, net income decreased $1.3 million, or
56.1%, from $2.4 million in the three months ended September 30, 1998 to
$1.1 million in the same period in 1999.

<PAGE>   14

NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THE NINE MONTHS ENDED
     SEPTEMBER 30, 1998

     Net revenue increased $19.3 million, or 22.9%, from $84.5 million in the
nine months ended September 30, 1998 to $103.9 million in the same period in
1999. We published 133 directories in the nine months ended September 30, 1999
compared to 112 in the same period in 1998. The net revenue growth was due to
$17.8 million from 28 new directories, $4.8 million from seven directories
for which the publication date moved into the period and growth in the same 98
directories published during both periods of $5.9 million; offset by $9.2
million of net revenues associated with 14 directories published in the
nine months ended September 30, 1998 but not in the same period in 1999.

     As a result of a combination of factors, including the addition of new
customers, price increases, increases in the amount of advertising by current
customers and new directory features such as colorization of ads, additional
ad sizes and additional headings, our same book revenue growth for the 98
directories published in both periods was 7.8%.

     Cost of revenues increased $3.4 million, or 21.3%, from $15.9 million in
the nine months ended September 30, 1998 to $19.3 million in the same period
in 1999. The increase was the result of $3.9 million of costs associated with
28 new directories published in the nine months ended September 30, 1999, and
$0.8 million in costs associated with seven directories published in the nine
months ended September 30, 1999, but not in the same period in 1998; offset by
$1.5 million of costs associated with 14 directories published during the nine
months ended September 30, 1998, but not in the same period in 1999. Costs for
the same 98 books decreased $0.4 million compared to the prior year. Production
support costs increased $0.6 million in the nine months ended September 30,
1999 due to the new directories published during the period.

     As a result of the above, gross profit increased $16.0 million, or
23.2%, from $68.6 million in the nine months ended September 30, 1998 to $84.6
million in the same period in 1999. Gross margin increased from 81.2% in the
nine months ended September 30, 1998 to 81.4% in the same period in 1999 as a
result of lower direct costs as a percentage of revenue on the directories
published in both periods and directories moving into the period.

     Sales and marketing expenses increased $9.0 million, or 26.2%, from
$34.1 million in the nine months ended September 30, 1998 to $43.1 million in
the same period in 1999. The increase was attributable to increases of $3.3
million in sales support costs, $4.8 million in direct sales costs and $0.9
million in the provision for bad debt.

     The increase in sales support costs of $3.3 million was due to $2.8
million in higher sales costs incurred by offices acquired since the third
quarter of 1998 and $0.5 million due to the reorganization of the sales
management structure in 1998. The increase in direct sales costs of $4.8
million was as follows: $4.5 million of additional costs were for the 28 new
directories, $1.0 million for seven directories moving into the period, and
$1.3 million of higher costs associated with the 98 same directories; offset by
$2.0 million of costs associated with 14 directories that published in the
nine months ended September 30, 1998 but not in the same period in 1999. Direct
sales costs as a percentage of revenue for the same 98 directories published
during both periods increased from 20.1% to 20.3% in the nine months ended
September 30, 1998 compared to the same period in 1999.

     General and administrative expenses increased $11.7 million, or 91.4%,
from $12.9 million for the nine months ended September 30, 1998 to $24.6
million for the same period in 1999. The increase was due to: amortization of
acquired customer base and other intangibles of $8.9 million and an increase in
incentive compensation costs and increases in other professional service costs
totaling $2.8 million.

<PAGE>   15

     As a result of the above factors, income from operations decreased $4.7
million, or 21.9%, from $21.6 million in the nine months ended September 30,
1998 to $16.9 million in the same period in 1999. Income from operations as a
percentage of net revenues decreased from 25.6% in the nine months ended
September 30, 1998 to 16.3% in the same period in 1999.

     Interest expense increased $3.3 million, or 23.6%, from $13.6 million in
the nine months ended September 30, 1998 to $16.9 million in the same period
in 1999 due to higher levels of debt to fund acquisitions. Tax expense incurred
in the nine months ended September 30, 1999 of $0.2 million is for state and
federal income tax expense for Target Directories of Michigan Inc., a wholly
owned subsidiary of TransWestern Publishing Company, LLC.

     As a result of the above factors, net income decreased $8.1 million, or
98.5%, from $8.2 million in the nine months ended September 30, 1998 to $0.1
million in the same period in 1999.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided by operating activities was $7.7 million in the nine
months ended September 30, 1999 compared to $11.6 million in the same period
in 1998. The decrease in cash provided by operations resulted primarily from an
increase in trade receivables and the write-off rate of doubtful accounts in
the nine months ended September 30, 1999 compared to the same period in the
prior year.

     Customer deposits (advance payments) have improved compared to the prior
year due to higher volume of net revenues and our efforts to collect more cash
at contract closing to reduce our exposure to uncollectable accounts. Advance
payments were $38.0 million in the nine months ended September 30, 1999 and
$34.7 million in the same period in 1998 for an increase of $3.3 million or
9.5%.

     Net cash used by investing activities was $40.3 million in the nine
months ended September 30, 1999 as compared to $14.3 million in the same period
in 1998. Investing activities consist primarily of cash used to acquire
directories. In the nine months ended September 30, 1999, $39.5 million was
spent compared to $7.8 million in the same period in the prior year. The prior
year's acquisition consisted of Mast Advertising and Publishing, Inc. ($8.4
million) and Target Directories of Michigan, Inc. ($5.4 million). Acquisitions
made in the nine months ended September 30, 1999 are discussed in note 3 of the
financial statements included in this Form 10-Q.

     Net cash provided by financing activities was $19.7 million in the nine
months ended September 30, 1999 as compared to $2.0 million used in the same
period in 1998. The increase in borrowings in 1999 is attributed to the funding
of acquisitions during the nine months ended September 30, 1999.

     In connection with the recapitalization of our company in October 1997,
we incurred significant debt. As of September 30, 1999 we had total outstanding
long term indebtedness of $232.3 million, including $142 million (including
unamortized premium) of Series D 9 5/8% Senior Subordinated Notes due 2007, and
$64.8 million of outstanding borrowings under the senior credit facility, which
ranks senior to the Series D notes.

     As of September 30, 1999 the borrowing capacity under the Company's
revolving loan agreement under its senior credit facility was $40 million and
$23 million was borrowed and $17 million was available under the agreement. In
October 1999, the senior credit facility was amended to provide the Company with
$30 million in additional borrowing capacity on its revolving loan agreement
and to make certain other changes to the senior credit facility. In October
1999, we purchased certain tangible and intangible assets of United Multimedia
(American Media) for a total of $16.0 million. See footnote 5 of the
consolidated financial statements, subsequent events, for additional
information on the amendments to the senior credit facility and the American
Media acquisition.

<PAGE>   16

     In May, 1999 we were required to make a semiannual interest payment of
$6.7 million on our Series D 9 5/8% Senior Subordinated Notes. Another, similar
payment is due in November of 1999.

     Our principal sources of funds are cash flows from operating activities
and available funds under our revolving credit facility. Based upon the
successful implementation of management's business and operating strategy, we
believe that these funds will provide us with sufficient liquidity and capital
resources to meet our current and future financial obligations, including the
payment of principal and interest on our notes, as well as to provide funds
for our working capital, capital expenditures and other needs. Our future
operating performance will be subject to future economic conditions and to
financial, business and other factors, many of which are beyond our control.
There can be no assurance that such sources of funds will be adequate and that
we will not require additional capital from borrowings or securities offerings
to satisfy such requirements. In addition, we may require additional capital
to fund future acquisitions and there can be no assurance that such capital
will be available.

YEAR 2000 READINESS STATEMENT

     Our Year 2000 ("Y2K") project team focused on four key readiness areas:

     - business computer systems -- addressed hardware and software used in
       our core operations;

     - computing infrastructure -- addressed network servers, operating
       software, voice networks, and phones;

     - end user computing -- addressed hardware and software used in our
       ancillary operations; and

     - vendors/ suppliers -- addressed the preparedness of our key
       suppliers.

     For each readiness area, we performed risk assessment, conducted
testing, and remediation, either retirement, replacement or conversion,
developed contingency plans to mitigate known risk, and communicated with
employees, suppliers, and other third parties to raise awareness of the Y2K
problem.

     Business Computer Systems, Computing Infrastructure, and End User
Computing Readiness Programs. We, with the assistance of third parties,
conducted an assessment of our internal applications and computer hardware.
Some software applications already were or have been made year 2000 compliant
and resources were assigned to address other applications based on their
importance and the time required to make them Y2K compliant. All of our
software remediation, Y2K compliance evaluation of hardware, including routers,
telecommunication equipment, workstations and other items are substantially
complete.

     In addition to applications and information technology hardware, we have
developed remediation/contingency plans for certain business critical systems
such as: embedded systems, facilities and other operations, such as financial
and banking systems. Business critical systems were tested for Y2K compliance
and service agreements for those systems were reviewed to confirm we will have
vendor support for such systems in Y2K.

     Vendors/Suppliers Readiness Program. This program focuses on minimizing
the risks associated with key suppliers. We have identified key suppliers and
have contacted them to solicit information on their Y2K readiness. To date, we
have received most responses, which indicate that the suppliers are either in
compliance or are in the process of developing remediation plans. We have also
developed supplier action lists and contingency plans for key suppliers,
including identification of alternative vendors and documentation of plans to
aid in minimizing any impact from the Y2K problem.

<PAGE>   17

     We estimate that total Y2K costs will be approximately $0.7 million. Y2K
costs incurred by the end of the third quarter of 1999 were approximately $0.65
million. Although management believes Y2K costs related to the readiness areas
described herein to be substantially complete, there can be no assurance
that there will not be unforeseen additional costs.

     Although our Y2K remediation efforts are largely complete, we cannot
assure you that unforseen complications will not arise or that third parties on
which the Company relies in its day to day operations will have adequately
remedied against potential Y2K complications.  If computer systems used by us
or our suppliers, the performance of products provided to us by our suppliers,
or the software applications we use to produce our products fail or experience
significant difficulties related to Y2K, our results of operations and
financial condition could be materially adversely affected.

FORWARD LOOKING STATEMENTS

     This Quarterly Report on Form 10Q contains forward-looking statements
which are made pursuant to the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995. Such forward-looking statements are based on
the beliefs of our management as well as on assumptions made by and information
currently available to us at the time such statements were made. When used in
this Quarterly Report on Form 10Q, the words "anticipate," "believe,"
"estimate," "expect," "intends" and similar expressions, as they relate to our
company are intended to identify forward-looking statements. Actual results
could differ materially from those projected in the forward-looking statements.
Important factors that could affect our results include, but are not limited
to, (i) our high level of indebtedness; (ii) the restrictions imposed by the
terms of our indebtedness; (iii) the turnover rate amongst our account
executives; (iv) the variation in our quarterly results; (v) risks related to
the fact that a large portion of our sales are to small, local businesses; (vi)
our dependence on certain key personnel; (vii) risks related to the acquisition
and start-up of directories; (viii) risks related to substantial competition in
our markets; (ix) risks related to changing technology and new product
developments; (x) the effect of fluctuations in paper costs;(xi) the
sensitivity of our business to general economic conditions; and (xii) risks
related to the success of our Year 2000 remediation efforts.

ITEM 3.   Quantitative and Qualitative Disclosures about Market Risk

     We are exposed to interest rate risk in connection with the term
loan and the revolving loans outstanding under our senior credit facility,
which bear interest at floating rates based on LIBOR or the prime rate plus an
applicable borrowing margin. As of September 30, 1999, there was approximately
$64.9 million outstanding under the term loan (at an interest rate of 7.8% at
such time) and $23.0 million outstanding under the revolving loans (at the
LIBOR rate of 7.5% at such time). Based on such balances, an immediate increase
of one percentage point in the applicable interest rate would cause an increase
in interest expense of approximately $0.9 million on an annual basis. We do
not attempt to mitigate this risk through hedging transactions. All of our
sales are denominated in U.S. dollars, thus we are not subject to any foreign
currency exchange risks.
