The Primary Convertible Debentures and the Optional Convertible Debentures, each as further described are referred to coll ectively herein as the "Convertible Debentures". The Convertible Debentures shall have the attributes substantially as outlined in the term sheet annexed as Schedule "A" hereto and as described in the Prospectus (as hereinafter defined).

The Underwriters understand that the Company is prepared to (i) authorize, create, issue and sell the Convertible Debentures and (ii) file a preliminary short form prospectus as soon as reasonably possible and a (final) short form prospectus will be filed by the Company in accordance with the procedures established by National Policy 43-201 of the Canadian Securities Administrators as soon as reasonably possible thereafter to qualify the Convertible Debentures for distribution in the Qualifying Provinces (as hereinafter defined). All dollar amounts referred to herein are in Canadian dollars unless indicated otherwise.

The Convertible Debentures will be issued pursuant to a trust indenture (the "Trust Indenture") to be dated on or prior to the Closing Date to be entered into between the Company and Computershare Trust Company of Canada as trustee (the "Trustee"). The Trust Indenture and the Convertible Debentures will provide that the Convertible Debentures will be convertible into the Class A Subordinate Voting Shares in the capital of the Company (the "Common Shares"). The Convertible Debentures will be convertible initially at a conversion rate of 71.4286 Common Shares per $1,000 principal amount of the Convertible Debentures. Additionally, the Company will have the option in certain circumstances and subject to certain conditions to (i) satisfy the amount to be paid upon redemption or repurchase of the Convertible Debentures by issuing Common Shares and (ii) satisfy the amount to be paid upon maturity of the Convertible Debentures by issuing Common Shares. In all such circumstances (including the conversion of the Convertible Debentures) the Common Shares to be issued by the Company shall be referred to herein as the "Underlying Shares".

Holders of Convertible Debentures will be entitled to the benefits of a resale registration rights agreement (the "Registration Rights Agreement") between the Company and the Underwriters dated the Closing Date. In accordance with the Registration Rights Agreement, pursuant to which the Company will agree to file with the SEC (as hereinafter defined) a resale registration statement under the U.S. Securities Act (as hereinafter defined) (the "Registration Statement") covering the resale of the Convertible Debentures and the Underlying Shares, and to use its reasonable best efforts to cause the Registration Statement to be declared effective.

The Company, as and to the extent indicated above, hereby grants to the Underwriters the right to purchase at their election up to an additional $10,000,000 principal amount of Optional Convertible Debentures for the purpose of covering over-allotments in the sale of the Primary Convertible Debentures. Any such election to purchase Optional Convertible Debentures may be exercised only by written notice from "[__________]"., on behalf of the Underwriters, to the Company at any time up to 24 hours prior to the Closing Date and setting forth the aggregate number of Optional Convertible Debentures to be purchased at the Closing Time.

		(i)	there should occur or commence, or be announced or threatened, any inquiry, action, suit, investigation or other proceeding (whether formal or informal); or any order is issued by any governmental authority; or any law or regulation is promulgated, changed or announced; which in the opinion of an Underwriter, acting reasonably, is expected to prevent or materially restrict the trading in or the Distribution of the Convertible Debentures or any other securities of the Company or would be expected to have a material adverse effect on the market price or value of the Convertible Debentures or other securities of the Company;
		(ii)	there shall occur any material change or changes (actual, anticipated, contemplated or threatened, financial or otherwise) in the business, affairs, operations, assets, liabilities (contingent or otherwise), capital or control of the Company (the "Condition of the Company"), or any change in a material fact or the Underwriters become aware of any undisclosed material information which in the reasonable opinion of the Underwriter, acting reasonably, would, or would be expected to have, a material adverse effect on the market price or value of the Convertible Debentures or any securities of the Company; or

then any of the Underwriters shall be entitled at its option in accordance with paragraph 18, to terminate its obligations under this agreement in respect of any Convertible Debentures not then purchased under this agreement by written notice to that effect given to the Company by the Closing Time.

12.

The Company agrees that all terms and conditions contained in paragraphs 1, 2 and 10 shall be construed as conditions, and any breach or failure by the Company to comply with any of such conditions shall entitle the Underwriters, or any of them, to terminate its obligations to purchase the Primary Convertible Debentures and Optional Convertible Debentures by notice to that effect given to the Company at or prior to the Closing Time, unless otherwise expressly provided in this agreement. The Underwriters may waive, in whole or in part, or extend the time for compliance with, any of such terms and conditions without prejudice to their rights in respect of any other of such terms and conditions or any other or subsequent breach or non-compliance; provided that to be binding on the Underwriters any such waiver or extension must be in writing and signed by all of the Underwriters.

		(iii)	any omission or alleged omission to state in the Prospectus, any Supplementary Material or any certificate of the Company or any officer of the Company delivered hereunder or pursuant hereto any fact, whether material or not (except facts relating solely to the Underwriters), required to be stated therein or necessary to make any statement therein not misleading in light of the circumstances under which it was made;
		(iv)	any order made or inquiry, investigation or proceedings commenced or threatened by any securities commission, stock exchange or other competent authority based upon any untrue statement, or omission or misrepresentation or alleged untrue statement, omission or misrepresentation (except a statement, omission or misrepresentation or

			alleged statement, omission or misrepresentation relating solely to the Underwriters) in the Prospectus or any Supplementary Material or based upon any failure to comply with Canadian Securities Laws and U.S. Securities Laws (other than any failure or alleged failure to comply by the Underwriters or their banking or selling group), preventing or restricting the trading in or the sale or Distribution of the Convertible Debentures in any of the Qualifying Provinces;
		(v)	the non-compliance or alleged non-compliance by the Company with any requirement of applicable securities legislation in connection with the transactions herein contemplated including the Company's non-compliance with any statutory requirement to make any document available for inspection;

	(d)	None of the Company and any of the Underwriters shall agree to any settlement of any claim, action, suit or proceeding referred to in this paragraph 13 unless the Company and each of the Underwriters has consented in writing thereto.
14.

The Underwriters shall not in any event be liable to contribute, in the aggregate, any amounts in excess of such aggregate fee or any portion thereof actually received. However, no party who has engaged in any fraud, fraudulent misrepresentation or negligence shall be entitled to claim

- 30 -

contribution from any person who has not engaged in such fraud, fraudulent misrepresentation or negligence.

	(b)	The rights to contribution provided in this paragraph 14 shall be in addition to and not in derogation of any other right to contribution which the Underwriters may have by statute or otherwise at law.
	(c)	In the event that the Company may be held to be entitled to contribution from the Underwriters under the provisions of any statute or at law, the Company shall be limited to contribution in an amount not exceeding the lesser of:

		(ii)	the amount of the aggregate fee actually received by the Underwriters from the Company hereunder.
	(d)	If the Underwriters have reason to believe that a claim for contribution may arise, they shall give the Company notice thereof in writing, but failure to notify the Company shall not relieve the Company of any obligation which it may have to the Underwriters under this paragraph 14.
	(e)	With respect to this paragraph 14, the Company acknowledges and agrees that the Underwriters are contracting on their own behalf and as agents for their directors, officers, employees and agents.
15.	If any provision of paragraph 13 or 14 is determined to be void or unenforceable in whole or in part, it shall be deemed not to affect or impair the validity of any other provision of this agreement and such void or unenforceable provision shall be severable from this agreement.

UNDERWRITING AGREEMENT

Term Sheet

MDC Partners Inc.

5-year Convertible Unsecured Subordinated Debentures			June 8, 2005

	Issuer:	MDC Partners Inc. ("MDC" or the "Company").
	Offering:	Convertible Unsecured Subordinated Debentures (the "Convertible Debentures")
	Amount:	C$40,000,000
	Price:	C$1,000 per Convertible Debenture.
	Underwriters Option:	The Company has agreed to grant the Underwriters an option to purchase up to an additional C$10,000,000 of Convertible Debentures on the same terms and conditions herein, to be exercisable at the discretion of the Underwriters at any time up to 24 hours prior to Closing of this offering.
	Issue Type:	Bought underwritten public issue, eligible for sale in all provinces of Canada, with the exception of Quebec, pursuant to a short form prospectus, to eligible investors in the United States pursuant to the registration exemptions provided by Rule 144A of the Securities Act of 1933 and internationally as permitted. The Convertible Debentures will be freely tradeable on the Toronto Stock Exchange without any requirement by a holder of such securities to certify to the Company and its transfer agent that a transfer is being made in compliance with the Securities Act of 1933. The Common Shares issued upon conversion will be freely tradeable on the Toronto Stock Exchange provided that such holder certifies (during the two year restricted period beginning on the date of issuance of the Convertible Debentures) to the Company and its transfer agent that the transfer is being made in compliance with the Securities Act of 1933, and will be listed under a different ticker symbol and CUSIP, which may limit holders liquidity.

Registration Rights:	A resale registration statement will be filed with the SEC by September 30, 2005 to permit the unrestricted resale of the Convertible Debentures and the underlying Common Shares by all selling securityholders of the Company that (a) have delivered a completed selling securityholder questionnaire to the Company and (b) are named as selling securityholders in such registration statement. In the event that a resale shelf registration statement is not effective by December 31, 2005, the coupon will increase by 0.50% for the first six month period, and, if the resale shelf registration statement is not effective by June 30, 2006, the coupon will increase by an additional 0.50%. The coupon will be reset to 8.00% per annum at the earlier of (x) the end of the six month period in which the resale shelf registration statement is declared effective, or (y) June 30, 2007.
Maturity:	June 30, 2010 ("Maturity Date").
Use of Proceeds:	The net proceeds to the Company of the offering will be used to reduce outstanding indebtedness.
Coupon:	8.00% per annum, payable in cash semi-annually in arrears on June 30^th and December 31^st of each year, commencing December 31, 2005. The Company may elect to pay the interest amount by delivering Class A Subordinate Voting Shares (the "Common Shares") to the indenture trustee (the "Trustee"), which would then be obligated to sell the Common Shares and use the proceeds to satisfy in full the interest obligation to the holders of the Convertible Debentures in cash. However, the Company is not relieved from ensuring that there is adequate cash to pay the interest due on a timely basis.
Certificates/CUSIP:	The Convertible Debentures will be held in global certificated form and will be held by a depositary for a book-entry clearance facility. The Convertible Debentures will be identified by a separate restricted CUSIP.
Conversion:	Each C$1,000 principal amount of Convertible Debenture will be convertible at any time prior to the Maturity Date (or after if the Convertible Debentures are not repaid on that date) or the date fixed for redemption, at the option of the holder, into 71.4286 Common Shares (based on a C$11.20 price on the TSX, the "Conversion Rate"), representing a conversion price of C$14.00 per Common Share (the "Conversion Price"). Holders who exercise conversion rights will be entitled to receive accrued interest up to the date of conversion. The Conversion Rate may be adjusted upon the occurrence of certain events, including for any cash dividend paid on the Common Shares of the Company.

- A-2 -

Redemption:

The Convertible Debentures will not be redeemable by the Company at any time prior to June 30, 2008.

From July 1, 2008, to June 30, 2009, the Convertible Debentures will be redeemable by the Company at par plus accrued and unpaid interest, provided that the volume weighted average trading price of the Common Shares on the Toronto Stock Exchange for at least 20 trading days in any consecutive 30-day period ending on the fifth trading day prior to the date on which the notice of redemption is given exceeds 125% of the Conversion Price. From July 1, 2009, until maturity the Convertible Debentures will be redeemable at par plus accrued and unpaid interest.

In each case, the Company is required to provide not more than 60 days and not less than 30 days prior notice of the redemption date.

Principal Payment:

Cash payment in an amount equal to the principal amount of the outstanding Convertible Debentures together with accrued and unpaid interest.

At the option of the Company on not more than 60 days and not less than 30 days prior notice, the Company may satisfy the obligation to pay the principal amount of the Convertible Debentures on maturity, redemption or repurchase pursuant to a change of control offer (as described below under "Change of Control") by the issue and delivery of that number of freely tradeable Common Shares obtained by dividing the principal amount of the Convertible Debentures by 95% of the Current Market Price of the Common Shares on the maturity, redemption or repurchase date other than in circumstances where an event of default has occurred.

Current Market Price:

Equal to the volume weighted average trading price of the Common Shares on the Toronto Stock Exchange for the 20 consecutive trading days ending five trading days preceding the maturity, redemption or repurchase date, as the case may be.

- A-3 -

Change of Control:	In the event that a Change of Control (to be defined in the Trust Indenture) occurs prior to June 30, 2008, the Company shall be required to make an offer to purchase for all of the outstanding Convertible Debentures at par plus an amount equal to the interest payments not yet received calculated from the date of Change of Control to June 30, 2008, discounted at the Government of Canada Yield. For these purposes, the Government of Canada Yield on any date shall mean the average of the yields determined by two registered Canadian investment dealers, selected by the Company, as being the yield to maturity on such date compounded semi-annually and calculated in accordance with generally accepted financial practice, which a non-callable Government of Canada Bond would carry if issued in Canadian dollars in Canada at 100% of its principal amount on such date with a maturity date of June 30, 2008. After June 30, 2008, the offer shall be at par plus accrued and unpaid interest.
Rank:	The Convertible Debentures will be direct unsecured obligations of the Company ranking subordinate to all liabilities except liabilities, which by their terms rank in rights of payment equally with or subordinate to the Convertible Debentures. The Convertible Debentures will rank pari passu with all subordinated debentures issued by the Company from time to time.
Purchase for Cancellation:	The Company may elect from time to time to purchase Convertible Debentures for cancellation in the market or by tender or private contract at any time subject to regulatory requirements. However, if an Event of Default has occurred the Company will not have the right to purchase the Debentures by private contract.
Eligibility:	Eligible under the usual statutes as well as for RRSPs, RRIFs, RESPs, and DPSPs and will not be foreign property for such plans and funds.
Listing:	The Convertible Debentures and the Common Shares issued upon conversion will be listed on the Toronto Stock Exchange. The Convertible Debentures and the Common Shares issued upon conversion will contain a modified form of the s. 607.1 Toronto Stock Exchange restricted legend, if necessary, to permit trades to occur on the Toronto Stock Exchange of the Convertible Debentures and the Common Shares issued upon conversion without the requirement that any restricted legend be removed prior to such trade.
Co-Leads:	"[__________]" and "[__________]"
Conditions:	This offer is subject to the standard terms and conditions of an underwriting of this type.
Closing:	On or about June 28, 2005.
Commission:	3.0%, payable upon Closing.
