      MDC PARTNERS INC. ANNOUNCES FINANCIAL RESULTS FOR THE THREE AND NINE
                        MONTHS ENDED SEPTEMBER 30, 2004

TORONTO, Ontario (November 4, 2004) - MDC Partners Inc. ("MDC Partners") today
announced its financial results for the third quarter and nine months ended
September 30, 2004. Consolidated revenue for the third quarter was $86.3
million, an increase of 33% from the $64.9 million in the same quarter last
year. Operating profit of $2.3 million was achieved, compared to $3.0 million
reported for the third quarter of 2003. The net loss for the quarter was $1.5
million, compared to net income of $3.2 million in 2003. Diluted loss per share
for the quarter ended September 30, 2004 was $0.07 versus diluted earnings per
share of $0.15 last year.

Consolidated revenue for the nine months was $237.4 million, an increase of 4%
from the $227.7 million reported in 2003. The net loss was $1.1 million versus
net income of $26.8 million in 2003. Diluted loss per share was $0.05 compared
to diluted earnings per share of $1.19 in the 2003 period.

Due to the significant impact that certain operating affiliates have on the
results of operations of the Company, the foregoing discussion and analysis of
the Company's results consolidate the equity-accounted affiliate operations of
the Marketing Communications Division (the "Combined" basis). As previously
disclosed, beginning September 22, 2004, MDC Partners consolidated the financial
results of Crispin Porter + Bogusky, LLC.

On a Combined basis, revenues were $98.0 million in the third quarter compared
to $71.4 million, an improvement of 37% or $26.6 million. Operating profit was
$4.1 million, a decrease of $0.5 million from the prior-year period. On the same
Combined basis, revenues for the nine months ended September 30, 2004 were
$272.8 million, an increase of 11% over the prior year. Operating profit was
$11.2 million, compared to an operating loss of $1.1 million in 2003.

Marketing Communications revenue on a Combined basis was $77.5 million for the
quarter, 51% more than the comparable $51.3 million reported in the third
quarter of 2003 primarily due to acquisitions completed in 2004 and organic
growth. Organic revenue increased 8.7% for the third quarter and 12.8% in the
year-to-date period. EBITDA (please see the reconciliation of EBITDA to
operating profit below) for the quarter was $8.0 million, an increase of 29%
from the $6.2 million earned in the same prior-year




period. EBITDA margins were 10.3% for the quarter versus 12.1% in the previous
year due to an increase in operating costs disproportionate to the increase in
revenue. For the nine months ended September 30, 2004, Marketing
Communications' Combined revenue was $215.6 million with EBITDA of $21.6
million, an increase of 46% and 40%, respectively, over the prior year.
However, excluding operating losses of a non-core marketing unit and investment
spending of a start-up unit, EBITDA was $9.8 million for the quarter and $27.3
million for the nine months ended September 30, 2004.

"We are extremely pleased with the progress that our partner companies have made
during the third quarter," said Miles S. Nadal, Chairman, President & CEO of MDC
Partners. "New business wins in the quarter were substantial including work for
Unilever, a major U.S.-based retailer, and Sprint."

Revenue attributable to Secure Products International ("SPI") totaled $20.5
million for the third quarter of 2004, an increase of $1.6 million or 8%
compared to the 2003 third quarter revenues. A significant increase in
production at Ashton Potter related to the USPS contract awarded in 2003
generated a 112% improvement in the revenues of the stamp operation. Operating
profits earned by SPI amounted to $1.3 million for the quarter compared to $0.8
million, primarily the result of increased production and profitability at
Ashton Potter and Placard. Operating income generated by Mercury was relatively
unchanged from the prior-year third quarter, despite the impact of the NHL
lockout on ticket revenues, while Metaca, the Canadian card operations,
experienced a decline in operating profits. Management continues to undertake
initiatives designed to reduce the cost structure and improve efficiencies at
Metaca. In connection with this effort, severance and other related charges of
$0.2 million were recorded in the quarter. SPI generated $2.1 million to EBITDA
for the third quarter, an increase of 79% versus the same period of 2003.

For the nine months ended September 30, 2004, SPI revenues totaled $56.5 million
compared to $96.2 million in the prior year. 2003 revenues include $49.0 million
related to an operation that was divested in the second quarter of 2003.
Operating profit for the nine months was $2.1 million compared to an operating
loss of $10.9 million in the prior year.

"We continue to manage our SPI assets and believe the prospects for market share
gains and growth in profitability are significant. However, our previously
stated strategy of realizing on our investment via an initial public offering
remains our ultimate objective," said Mr. Nadal. "The expected improvement in
operating performance of the Division combined with the relative weakness of the
Canadian income trust market has moved our timetable for such a transaction."

Corporate and other operating expenses increased from $3.8 million in the 2003
third quarter to $5.8 million this quarter as a result of increased compliance
costs associated with US GAAP reporting and Sarbanes-Oxley legislation, an
increase in the provision for stock-based compensation, and an increase in
overhead costs in connection with the establishment of a US corporate office in
New York. Year to date, corporate and other operating expenses were $17.1
million compared to $8.8 million in the prior year.

On September 22, MDC Partners entered into a new revolving credit agreement with
a syndicate of banks led by JP Morgan Chase, including Toronto Dominion Bank,
Bank of Montreal, Bank of Nova Scotia and Canadian Imperial Bank of Commerce,
which provided for borrowings of up to $100 million. At the same time, a cash
management program was established with partner companies to centrally manage a
substantial portion of their cash balances. This cash management program,
together with the initial use of the credit facility, repaid in full the
outstanding balances on the Company's two senior and one mezzanine credit
facilities and a term debt facility, and reduced MDC Partners' debt by
approximately $45 million. The resultant consolidation of the Company's various
debt instruments has also amounted to a reduction in weighted average borrowing
rates of approximately 250 basis points.



During the third quarter, upon further review of the Company's interest in an
affiliate, the Company determined that it should have consolidated the financial
results of this affiliate for the quarter ended June 30, 2004. As a result, the
Company will be filing an amended Form 10-Q for the periods ended June 30, 2004.
The amended results for both the second quarter and six-month periods ended June
30, 2004 increased operating expenses by $0.7 million with corresponding
adjustments to income taxes, equity in affiliates and minority interest and had
no impact on the Company's revenues, net earnings nor its earning per share.

During the quarter the Company repurchased 616,000 shares under a normal course
issuer bid at an average price of $11.32 per share for total cash consideration
of $7.0 million.

"Our prospects for the future are truly exciting. Everyday, we deliver
world-class ideas and execution for our clients, helping to grow their
businesses," said Mr. Nadal.
