           Virtue, J. Brian O'Neill and CRW Financial, Inc. are referred to
           herein collectively as the "Stockholder Support Agreement
           Stockholders."

           owned by each of the Stockholder Support Agreement Stockholders is
           set forth on Schedule II to this Schedule 13D. Pursuant to the

           Stockholders have agreed to vote or direct the vote of all shares of
           Common Stock of the Issuer over which such person has voting power or
           control (the "Subject Shares") as follows:

               (1) At the Issuer stockholders meeting to be held to vote on the 
           Merger and the Merger Agreement (or at any adjournment thereof) or in
           any other circumstances upon which a vote, consent or other approval
           with respect to the Merger or the Merger Agreement is sought, the
           Stockholder Support Agreement Stockholders shall vote (or cause to be
           voted) the Subject Shares in favor of the Merger, the adoption of the
           Merger Agreement and the approval of the terms thereof and each of
           the other transactions contemplated by the Merger Agreement.

               (2) At any meeting of stockholders of Issuer or at any
           adjournment thereof or in any other circumstances upon which the
           Stockholder Support Agreement Stockholder vote, consent or other
           approval is sought, the Stockholder Support Agreement Stockholders
           shall vote (or cause to be voted) the Subject Shares against (i) any
           merger agreement or merger (other than the Merger Agreement and the
           Merger), consolidation, combination, sale of substantial assets,
           reorganization, recapitalization, dissolution, liquidation or winding
           up of or by Issuer or any subsidiary thereof or any other Acquisition
           Proposal (as defined in the Merger Agreement) or (ii) any amendment
           of Issuer's Certificate of Incorporation or Bylaws or other proposal
           or transaction involving Issuer or any Issuer subsidiary, which
           amendment or other proposal or transaction would in any manner
           impede, frustrate, prevent or nullify the Merger, the Merger
           Agreement or any of the other transactions contemplated by the Merger
           Agreement or change in any manner the voting rights of any class of
           capital stock of Issuer. The Stockholder Support Agreement
           Stockholders further agree not to commit or agree to take any action
           inconsistent with the foregoing.

               (3) Contemporaneously with the execution of the Stockholder
           Support Agreements the Stockholder Support Agreement Stockholders:
           (i) delivered to IDRC a proxy which proxy is irrevocable to the
           fullest extent permitted by law with respect to the Subject Shares
           (the "Proxy"); and (ii) have agreed to cause to be delivered to IDRC
           an additional proxy executed on behalf of the record owner of any
           issued and

           outstanding shares of Issuer Common Stock that are owned beneficially
           (but are not owned of record) by the Stockholder Support Agreement
           Stockholders.

               (4) Except for 678,410 of the Subject Shares subject to
           outstanding warrants granted by CRW Financial, Inc. (the "CRW Warrant
           Shares"), the Stockholder Support Agreement Stockholders agree not to
           (i) sell, transfer, pledge, assign or otherwise dispose of
           (collectively, "Transfer"), or enter into any contract, option or
                           --------                                         
           other arrangement (including any profit-sharing arrangement) with
           respect to the Transfer of the Subject Shares to any person or (ii)
           enter into any voting arrangement, whether by proxy, voting
           agreement, voting trust or otherwise, in relation to the Subject
           Shares. The Stockholder Support Agreement Stockholders further agree
           not to commit or agree to take any of the foregoing actions.
           Notwithstanding the foregoing, CRW Financial, Inc. may Transfer all
           of the CRW Warrant Shares upon exercise of the associated warrants.
           In addition, the Stockholder Support Agreement Stockholders may
           Transfer all or any portion of the Subject Shares held by such
           Stockholder Support Agreement Stockholders by way of gift or for
           estate planning purposes, provided that any such transferee shall 
           first be required to execute a joinder to the Stockholder Support 
           Agreement whereby such transferee agrees to be bound by all of the
           terms and conditions thereof.

               The foregoing summary of the voting aspects of the Stockholder
           Support Agreements is qualified in its entirety by reference to the
           forms of the TeleSpectrum Stockholder Support Agreements, included as
           Exhibits 99.2 and 99.3, and incorporated herein in their entirety by
           reference.
 
               (c)  Not applicable.

               (d) As a result of the Merger, certain members of the board of
           directors or executive officers of IDRC may be elected or appointed
           to the board of directors or may serve as employees of the Issuer,
           including Jeffrey Stiefler and Paul Grinberg. IDRC will cease to
           exist and each member of the board of directors of IDRC will resign.
           In addition, the executive officers of IDRC will be terminated,
           provided, however, that certain executive officers of IDRC may serve
           as employees of the Issuer.

               (e)  See Item 4(a) above.

               (f) - (g)  Upon consummation of the Merger, IDRC will merge with
           and into the Issuer and IDRC will cease to exist.

               (j) Other than as described above, IDRC has no plan or proposal
           which relates to, or may result in, any of the matters listed in
           Items 4(a) - (i) of this Schedule 13D (although IDRC reserves the
           right to develop such plans).
  
Item 5.    Interest in Securities of the Issuer

               (a) - (b)  As a result of the Stockholder Support Agreements,
           IDRC has shared power to vote an aggregate of 9,894,727 shares of
           Common Stock (which includes 739,660 shares of Common Stock
           underlying warrants and 824,167 shares of Common Stock underlining
           options) of the Issuer for the limited purposes described in Item 4
           above. Such shares constitute approximately 37.0% of the issued and
           outstanding shares of capital stock of the Issuer on a fully-diluted
           basis (after giving effect to the exercise of all outstanding options
           and warrants described above) as of January 14, 1999.

               To IDRC's knowledge, no shares of Common Stock of the Issuer are
           beneficially owned by any of the persons named in Schedule I, except
           for such beneficial ownership, if any, arising solely from the
           Stockholder Support Agreements.

               Set forth in Schedule III to this Schedule 13D is the name of and
           certain information regarding each person or entity with whom IDRC
           shares the power to vote or to direct the vote of Common Stock of the

                                  THE MERGER

     Section 1.1  The Merger.  Subject to the terms and conditions hereof and
in accordance with the General Corporation Law of the State of Delaware, as
amended (the "DGCL"), at the Effective Time (hereinafter defined): (a) IDRC
              ----                                                         
shall be merged with and into TeleSpectrum and the separate existence of IDRC
shall cease; (b) TeleSpectrum, as the surviving corporation in the Merger (the

- ----------------------                                                        
laws of the State of Delaware, (ii) shall retain its present name and (iii)

accordance with the DGCL; (c) the Certificate of Incorporation of TeleSpectrum,
as in effect immediately prior to the Effective Time, shall continue as the
Certificate of Incorporation of the Surviving Corporation; and (d) the Bylaws of
TeleSpectrum, as in effect immediately prior to the Effective Time, shall
continue as the Bylaws of the Surviving Corporation.  From and after the
Effective Time, the Merger will have all the effects provided by applicable law
and as set forth in this Agreement.

     Section 1.2  Stockholder Meetings, Closing, Effective Time of the Merger.
TeleSpectrum and IDRC shall each submit this Agreement to the holders of all of
their respective securities that are entitled to vote on this Agreement for
approval and adoption at meetings, or, in the case of IDRC, by consent in lieu
of a meeting, to be held as soon as practicable following the date of this
Agreement in accordance with Section 4.5 hereof.  Subject to this Agreement
receiving all requisite stockholder approvals and subject to the other
provisions of this Agreement, the parties shall hold a closing (the "Closing")
                                                                     -------  
on the next business day (or such later date as the parties hereto may agree)
following the later of (a) the first business day on which the stockholders of
IDRC and TeleSpectrum have each approved the Merger Agreement, or (b) the first

                                              ------------                
(Philadelphia time) at the offices of Morgan, Lewis & Bockius LLP, 1701 Market
Street, Philadelphia, Pennsylvania, or at such other time or place as the
parties agree.  On the Closing Date, the parties shall cause the Merger to
become effective by filing a certificate of merger (the "Certificate of Merger")
                                                         ---------------------  
with the Secretary of State of the State of Delaware in such form as required
by, and executed in accordance with the relevant provisions of,

                                      -2-
<PAGE>
 
the DGCL (the date and time of such filing, or such later date or time agreed
upon by TeleSpectrum and IDRC set forth therein, the "Effective Time.")
                                                      --------------   

     Section 1.3  Conversion and Cancellation of Securities.

          (a)  At the Effective Time and subject to Section 1.5 hereof, all (i)
shares of IDRC Common Stock and (ii) options, warrants and other rights (the
"Options") exercisable for, or providing the right to acquire, IDRC Common Stock
- --------                                                                        
that are issued and outstanding immediately prior to the Effective Time (other
than any shares of IDRC Common Stock described in Section 1.3(c) hereof) shall,
by virtue of the Merger and without any action on the part of the holder
thereof, be converted into the right to receive an aggregate of 9,200,000 shares
(the "Merger Shares") of TeleSpectrum Common Stock and warrants (the "Warrants")
      -------------                                                   --------  
exercisable for an aggregate of 3,000,000 shares (the "Warrant Shares") of
                                                       --------------     
TeleSpectrum Common Stock.  The Warrants shall contain such other terms and
conditions set forth in the form attached as Exhibit C hereto. Notwithstanding
                                             ---------                        
the foregoing, (i) no fractional shares of TeleSpectrum Common Stock shall be
issued and, in lieu thereof, a cash payment shall be made pursuant to Section
1.4(g) hereof, and (ii) the number of Merger Shares and Warrants issuable
pursuant to Section 1.3(a) shall be reduced on a proportional basis in an
aggregate amount equal to the number of Merger Shares and Warrants that would
have been received by holders of any Appraisal Shares (as such term is defined
in Section 1.3(c) hereof).   The effect of the foregoing means that (A) each
share of IDRC Common Stock that is issued and outstanding immediately prior to
the Effective Time (other than any shares of IDRC Common Stock described in
Section 1.3(c) hereof) will be convertible into (i) that number of Merger Shares
equal to 9,200,000 divided by the Total IDRC Shares Outstanding, the product
being rounded, if necessary, up or down, to the nearest whole share and (ii) a
Warrant exercisable for that number of Warrant Shares equal to 3,000,000 divided
by the Total IDRC Shares Outstanding, the product being rounded, if necessary,
up or down, to the nearest whole share, and (B), subject to Sections 1.5 and 1.6
hereto, a holder of Options will be entitled to receive, upon exercise, on
account of each share of IDRC Common Stock (i) that number of Merger Shares
equal to 9,200,000 divided by the Total IDRC Shares Outstanding, the product
being rounded, if necessary, up or down, to the nearest whole share and (ii) a
Warrant exercisable for that number of Warrant Shares equal to 3,000,000 divided
by the Total IDRC Shares Outstanding, the product being rounded, if necessary,
up or down, to the nearest whole share.  As used herein, the term "Total IDRC
Shares Outstanding" means the total number of shares of IDRC Common Stock and
the total number of shares of IDRC Common Stock issuable upon exercise of
Options that are issued and outstanding immediately prior to the Effective Time.

          (b)  At the Effective Time, (i) each outstanding share of Series A
Preferred Stock, shall be exchanged for $20 in cash, and (ii) all accrued and
unpaid dividends then payable in Series A-1 Preferred Stock, par value $.001 per
share, of IDRC (the "Series A-1 Preferred Stock"), with respect to the
                     --------------------------                       
outstanding shares of Series A Preferred Stock, shall be paid in cash in the
manner set forth in Article IV, Section E.1 of IDRC's Amended and Restated
Certificate of Incorporation in effect as of the Effective Time.

          (c)  At the Effective Time, each share of IDRC Common Stock held in
the treasury of IDRC immediately prior to the Effective Time, shall by virtue of
the Merger and without any action on the

                                      -3-
<PAGE>
 
part of the holder thereof, be automatically canceled and retired and cease to
exist, and no cash, securities or other property shall be payable in respect
thereof.

          (d)  The holders of shares of TeleSpectrum Common Stock shall not be
entitled to appraisal rights under the DGCL.  The holders of shares of IDRC
Common Stock held by a holder who, pursuant to Section 262 of the DGCL or any
successor provision, has the right to demand and properly demands an appraisal
of such shares of IDRC Common Stock ("Appraisal Shares"), shall not be converted
                                      ----------------                          
into the right to receive the Merger Consideration (as defined in Section
1.3(e)), on account of each share of IDRC Common Stock held by such holder,
unless such holder fails to perfect or otherwise loses such holder's right to
such appraisal, if any.  If, after the Effective Time, such holder fails to
perfect or loses any such right to appraisal, each such share of IDRC Common
Stock held by such holder shall be treated as a share of IDRC Common Stock that
had been converted as of the Effective Time into the right to receive the Merger
Consideration.  At the Effective Time, any holder of Appraisal Shares shall
cease to have any rights with respect thereto, except the rights provided in
Section 262 of the DGCL or any successor provision and as provided in the
immediately preceding sentence.  IDRC shall give prompt notice to TeleSpectrum
of any demands received by IDRC for appraisal of shares of IDRC Common Stock.

          (e)  The number of Merger Shares and Warrants to be issued pursuant to
this Agreement shall not be affected by reason of any reclassification,
recapitalization, split-up, combination or exchange of shares, or any dividend
payable in stock shall be declared thereon with a record date within such period
involving the IDRC Common Stock or the Options.  The number of Merger Shares and
Warrants to be issued pursuant to this Agreement shall not be affected by reason
of any reclassification, recapitalization, split-up, combination or exchange of
shares, or any dividend payable in stock shall be declared thereon with a record
date within such period involving the TeleSpectrum Common Stock or the Options.
The Merger Shares and Warrants issued on account of each share of IDRC Common
Stock and issuable on account of each share of IDRC Common Stock underlying the
Options as a result of the Merger shall be equal.  The number of Merger Shares
and Warrants issuable in exchange for each share of IDRC Common Stock and each
share of IDRC Common Stock underlying the Options is sometimes referred to
herein as the "Merger Consideration."
               --------------------  

     Section 1.4  Exchange of Certificates.

          (a)  Subject to Section 1.6 hereof, as soon as practicable after the
Effective Time, TeleSpectrum shall mail to each person who was, at the Effective
Time, a holder of record of a certificate or certificates that immediately prior
to the Effective Time evidenced outstanding shares of IDRC Common Stock or
shares of Series A Preferred Stock (the "Certificates") (i) a letter of
                                         ------------                  
transmittal specifying that delivery shall be effected, and risk of loss and
title to the Certificates shall pass, only upon delivery of the Certificates to
TeleSpectrum, which shall be in a form and contain any other provisions as
TeleSpectrum and IDRC may reasonably agree, and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for the Merger
Consideration receivable on account of each share of IDRC Common Stock
represented thereby or the cash receivable on account of each share of Series A
Preferred Stock represented thereby.  Upon the proper surrender of Certificates
to TeleSpectrum, together with a properly completed and duly executed letter of
transmittal and such other documents as may be required by TeleSpectrum, the
holder of such Certificate shall be entitled to receive in exchange therefor, in
the

                                      -4-
<PAGE>
 
case of holders of IDRC Common Stock, certificates representing the shares
of TeleSpectrum Common Stock and Warrants that such holder has the right to
receive pursuant to the terms hereof (together with any dividend or distribution
with respect thereto made after the Effective Time and any cash paid in lieu of
fractional shares pursuant to Section 1.4(g)), and, in the case of holders of
Series A Preferred Stock, cash in payment of the full exchange price and accrued
and unpaid dividends.  Each Certificate so surrendered shall be canceled. If any
portion of the Merger Consideration on account of IDRC Common Stock or cash on
account of Series A Preferred Stock is to be paid to a person other than the
person who is the record holder of the IDRC Common Stock or Series A Preferred
Stock, as applicable, at the Effective Time, it shall be a condition to such
payment that the Certificate evidencing the IDRC Common Stock or Series A
Preferred Stock so surrendered shall be properly endorsed or otherwise be in
proper form for transfer and that it be accompanied by all documents required to
evidence and effect such transfer and by evidence reasonably satisfactory to the
TeleSpectrum and IDRC that any applicable stock transfer tax has been paid.

          (b)  After the Effective Time, each outstanding Certificate which
theretofore represented shares of IDRC Common Stock shall, until surrendered for
exchange in accordance with this Section 1.4, be deemed for all purposes to
evidence ownership of whole shares of TeleSpectrum Common Stock and Warrants
into which the shares of IDRC Common Stock (which, prior to the Effective Time,
were represented thereby) shall have been so converted.  After the Effective
Time, each outstanding Certificate which theretofore represented shares of
Series A Preferred Stock shall be deemed for all purposes to have been converted
and to evidence only that cash amount payable upon conversion, without the right
to receive any interest from the Effective Time until the time received by the
holder.

          (c)  At the Effective Time, the stock transfer books of IDRC shall be
closed and no transfer of any securities of IDRC shall thereafter be made.

          (d)  Neither TeleSpectrum nor IDRC will be liable to any holder of
shares of IDRC Common Stock for any Merger Consideration or any dividends or
distributions with respect thereto or cash payable in lieu of fractional shares
pursuant to Section 1.4(g) hereof or to any holder of shares of Series A
Preferred Stock for any cash, in each case which is delivered to a state
abandoned property administrator or other public official pursuant to any
applicable abandoned property, escheat or similar law.

          (e)  If any Certificates shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the person claiming such
Certificates to be lost, stolen or destroyed, TeleSpectrum will deliver in
exchange for such lost, stolen or destroyed Certificates, the Merger
Consideration or cash, as applicable, for the shares represented thereby,
deliverable in respect thereof, as determined in accordance with the terms
hereof.  When authorizing such payment in exchange for any lost, stolen or
destroyed Certificates, the person to whom the Merger Consideration or cash, as
applicable, is to be issued, as a condition precedent to such delivery, shall
give TeleSpectrum a bond or indemnity reasonably satisfactory to TeleSpectrum,
its transfer agent and their respective insurance carriers against any claim
that may be made against TeleSpectrum with respect to the Certificates alleged
to have been lost, stolen or destroyed.

                                      -5-
<PAGE>
 
          (f)  No dividend or other distribution declared or made after the
Effective Time with respect to the Merger Consideration with a record date after
the Effective Time shall be paid to the holder of any unsurrendered Certificate
with respect to the shares of TeleSpectrum Common Stock issuable upon surrender
thereof until the holder of such Certificate shall surrender such Certificate in
accordance with Section 1.4(a).  Subject to the effect of applicable law,
following surrender of any such Certificate there shall be paid, without
interest, to the record holder of certificates representing whole shares of
TeleSpectrum Common Stock issued in exchange therefor: (i) at the time of such
surrender, the amount of dividends or other distributions with a record date
after the Effective Time theretofore paid with respect to such whole shares of
TeleSpectrum Common Stock; and (ii) at the appropriate payment date, the amount
of dividends or other distributions with a record date after the Effective Time
but prior to surrender of such Certificate and a payment date subsequent to such
surrender payable with respect to such whole shares of TeleSpectrum Common
Stock.

          (g)  No certificates or scrip evidencing fractional shares of
TeleSpectrum Common Stock shall be issued upon the surrender for exchange of
Certificates, and such fractional share interests shall not entitle the owner
thereof to any rights of a stockholder of TeleSpectrum.  In lieu of any such
fractional shares, each holder of a Certificate previously evidencing IDRC
Common Stock, upon surrender of such Certificate for exchange pursuant to this
Article I, shall be paid an amount in cash (without interest), rounded to the
nearest cent, determined by multiplying (a) the closing price for a share of
TeleSpectrum Common Stock on the Nasdaq National Market System (the "NMS") on
                                                                     ---     
the first business day immediately following the Effective Time, by (b) the
fractional interest to which such holder would otherwise be entitled (after
taking into account all shares of IDRC Common Stock held of record by such
holder at the Effective Time).

     Section 1.5  Options.

          (a)  Except as set forth in Section 1.5(b), all Options outstanding
immediately prior to the Effective Time, shall terminate and neither IDRC nor
TeleSpectrum will have any obligation thereunder to the extent such Options are
not exercised prior to the Effective Time.

          (b)  Subject to the other terms and conditions in this Section 1.5, in
lieu of the termination of Options as set forth in Section 1.5(a), each holder
of outstanding Options may elect, prior to the Effective Time, to have any
Option held by such holder assumed by TeleSpectrum and become a new option (an
"Assumed Option") to purchase Merger Shares and Warrants and containing
substantially the same terms and conditions as are in effect for the original
Option outstanding immediately prior to the Effective Time only if such holder
(i) agrees to place in escrow in accordance with Section 1.6 of this Agreement,
a portion of the Assumed Option (an "Escrow Option") that is exercisable solely
for that number of shares of TeleSpectrum Common Stock equal to (A) the product
of (1) the total number of Shares of IDRC Common Stock underlying such Assumed
Option immediately prior to the Effective Time divided by the Total IDRC Shares
Outstanding, and (2) $12,000,000 divided by the "Trading Value" (as defined in
Section 1.6(b)), and (ii) completing and returning to IDRC prior to the
Effective Time a notice of election of assumption to be provided by IDRC (in
form and substance acceptable to TeleSpectrum) to each holder of Options as soon
as practicable after the date hereof.  Each Assumed Option shall be evidenced by

used herein, the term "Trading Value" means the average closing price of one
share of TeleSpectrum Common Stock as quoted on the NMS during the 25 trading
days immediately preceding the Closing Date. For purposes of calculating the
Trading Value of the Escrow Securities, no value shall be ascribed to the Escrow
Options other than the value of each share of TeleSpectrum Common Stock
underlying the Escrow Options, each of which shall be valued at the Trading
Value. The Escrow Securities, together with all cash and non-cash dividends and
other property at any time received or otherwise distributed on, in respect of
or in exchange for any or all of the Escrow Securities, all securities hereafter

Escrow Agent in accordance with the terms of an Indemnity Escrow Agreement
substantially in the form attached hereto as Exhibit D.  The Indemnity Escrow

Agent shall hold the Escrow Property pursuant to the Indemnity Escrow Agreement
until the later of: (a) the fifteen month anniversary of the Closing Date; or
(b) the resolution of any claim for indemnification or payment that is pending
on the fifteen month anniversary of the Closing Date.

          (d)  The IDRC Stockholders (and the IDRC Optionholders to the extent
such optionholders exercise Assumed Options prior to the expiration of the
Indemnity Escrow Agreement) shall be entitled to exercise all voting powers
incident to the Escrow Property held by the Indemnity Escrow Agent as their
nominee, but shall not be entitled to exercise any investment or dispositive
powers over such Escrow Property.

consolidated balance sheets of IDRC and the IDRC Subsidiaries at November 30,
1998 and 1997 and related consolidated statements of operations, stockholders'
equity and cash flows for the 11-month periods then ended, all of which have
been prepared in accordance with generally accepted accounting principles
("GAAP") consistently applied throughout the periods involved (except as may be

indicated in the notes thereto). Such balance sheets, including the related
notes, fairly present in all material respects, the consolidated financial
position, assets and liabilities (whether accrued, absolute, contingent or
otherwise) of IDRC and the IDRC Subsidiaries at the dates indicated and such
consolidated statements of operations, stockholders' equity and cash flows
fairly present the consolidated results of operations, stockholders' equity and

Other than those year-end adjustments specified on the IDRC Schedule, the
unaudited consolidated financial statements as of and for the period ending
November 30, 1998, contain all adjustments, which are solely of a normal
recurring nature, necessary to present fairly the financial position at November
30, 1998 and the results of operations and changes in stockholders' equity and
cash flows for the 11-month period then ended. (The unaudited consolidated
balance sheet of IDRC and the IDRC Subsidiaries at November 30, 1998 described

                                    ------------------
receivable included on the IDRC Balance Sheet are bona fide accounts receivable
created in the ordinary course of business. Except as set forth on the IDRC

Officers, is reasonable in light of past accounts receivable collection history
and any known developments or trends. As used herein, the term "Knowledge of the
Designated IDRC Officers" means to the knowledge of either Jeffrey A. Stiefler
or Paul J. Grinberg after conducting such investigation as would be reasonably
be expected of the chief executive officer or chief financial officer, as
applicable, to determine the accuracy of their knowledge.

          (e)  incurred or paid any material liabilities, other than liabilities
incurred or paid in the ordinary course of business consistent with past
practice, discharged or satisfied any material Lien, or failed to pay or
discharge when due any liabilities of which the failure to pay or discharge has
caused or would reasonably be expected to cause an IDRC Material Adverse Effect;
or

          (f)  taken or been subject to any other action or event that would
have required the consent of TeleSpectrum pursuant to Section 4.1 hereof.

     Section 2.10  Indebtedness; Absence of Undisclosed Liabilities.  The
IDRC Schedule discloses as of the date hereof all indebtedness for money
borrowed by IDRC or any IDRC Subsidiary including the payee, the original
principal amount of the loan, the current unpaid balance of the loan, the
interest rate and the maturity date.  To the Knowledge of the Designated IDRC
Officers, neither IDRC nor any IDRC Subsidiaries have any material indebtedness,
liability or obligation of any kind (whether accrued, absolute, asserted or
unasserted, contingent or otherwise) except (i) as and to the extent reflected,
reserved against or otherwise disclosed on the IDRC Balance Sheet or the IDRC
Schedule, (ii) for liabilities and obligations incurred subsequent to November
30, 1998 in the ordinary course of business, and (iii) liabilities under any

and the IDRC Subsidiaries have good and marketable title to, or in the case of

and (d) Liens, if any, that do not materially detract from the value, or
interfere with the present or proposed use, of the properties subject thereto
("Permitted Liens").  All buildings, structures, facilities, equipment and other

acquired since the date thereof are in good operating condition and repair,
subject to normal wear and maintenance, are useable in the regular and ordinary
course of business of IDRC and the IDRC Subsidiaries and, except where the
failure to conform would not individually or in the aggregate result in an IDRC
Material Adverse Effect, conform to all applicable laws, statutes, ordinances,
codes, rules and regulations and Authorizations (hereinafter defined) relating
to their construction, use and operation.

     Section 2.12  Contracts.

          (a)  The IDRC Schedule lists each written or oral contract, agreement,
arrangement, lease, instrument, mortgage or commitment ("Contract") to which

$100,000 individually or in the aggregate with respect to any party or related
parties; (ii) which, if terminated, would

result in an IDRC Material Adverse Effect; (iii) which is with any present or

the IDRC Subsidiaries nor, to IDRC's knowledge, any other parties, have violated
any provision of, or committed or failed to perform any act which with notice,

Entities and other persons which are necessary for the lawful conduct of their
respective businesses and their use and occupancy of their assets and properties
in the manner currently conducted, used and occupied, except where the failure
to hold any of the foregoing would not have an IDRC Material Adverse Effect.
All of such Authorizations are valid, in good standing and in full force and
effect and IDRC and the IDRC Subsidiaries have duly performed in all material
respects all of their respective obligations under such Authorizations.  No

other than Authorizations, the termination or revocation of which would not have
an IDRC Material Adverse Effect or would result in any other material impairment
of the rights of the holder

                                     -14-

other governmental charges or impositions (including all income tax,
unemployment compensation, social security, payroll, sales and use, excise,

of assessment or proposed assessment in connection with any Taxes or Tax Returns
and, to IDRC's knowledge, there are not pending tax examinations of or tax
claims asserted against IDRC or the IDRC Subsidiaries or any of their respective
assets or properties. Neither IDRC nor any IDRC Subsidiary has extended, or
waived the application of, any statute of limitations of any jurisdiction
regarding the assessment or collection of any Taxes with respect to taxable
periods (or partial periods) ending on or prior to the Closing Date.

          (d)  There are no tax liens (other than any lien for current taxes not
yet due and payable) on any of the assets or properties of IDRC or the IDRC
Subsidiaries.  IDRC has no knowledge of any basis for any additional assessment
of any Taxes.  IDRC and the IDRC Subsidiaries have made all deposits required by
law to be made with respect to employees' withholding and other employment
taxes, including the portion of such deposits relating to taxes imposed upon
IDRC or the IDRC Subsidiaries with respect to taxable periods (or partial
periods) ending on or prior to the Closing Date.

Subsidiary and Joint Venture of TeleSpectrum, the jurisdiction of its
organization and the amount of its securities outstanding and the owners
thereof.  Each Subsidiary of TeleSpectrum (the "TeleSpectrum Subsidiaries") is
                                                -------------------------     
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization.  Each TeleSpectrum Subsidiary has all
requisite power and authority to carry on its business as it has been and is now
being conducted and to own, lease and operate the assets and properties used in
connection therewith.  Each TeleSpectrum Subsidiary is duly qualified as a
foreign corporation authorized to do business and is in good standing in every
jurisdiction in which such qualification is required or good standing is
recognized, all of which jurisdictions are disclosed in the TeleSpectrum
Schedule, except where the failure to be so qualified would not have a
TeleSpectrum Material Adverse Effect.  Except as set forth in the TeleSpectrum
Schedule, all issued and outstanding shares of capital stock of each
TeleSpectrum Subsidiary, are owned by TeleSpectrum free and clear of Liens.
There are no existing subscriptions, options, warrants, convertible securities,
calls, commitments, agreements, conversion rights or other rights of any
character (contingent or otherwise) calling for or requiring the issuance,
transfer, sale or other disposition of any shares of the capital stock of any
TeleSpectrum Subsidiary, or calling for or requiring the issuance of any
securities or rights convertible into or exchangeable for shares of capital
stock of any TeleSpectrum Subsidiary, nor is TeleSpectrum or any TeleSpectrum
Subsidiary subject to any obligation (contingent or otherwise) to repurchase,
redeem or otherwise acquire shares of capital stock of any TeleSpectrum
Subsidiary, in any case except as set forth in the TeleSpectrum Schedule.
Except for the TeleSpectrum Subsidiaries and the Joint Ventures of TeleSpectrum
or as set forth in the TeleSpectrum Schedule, neither TeleSpectrum nor any
TeleSpectrum Subsidiary directly or indirectly (i) owns or controls any shares
of any corporation nor has any voting securities of, or economic interest in,

TeleSpectrum Common Stock upon the exercise of outstanding stock options or
warrants. All of the issued and outstanding shares have been duly authorized and
are validly issued and outstanding, fully paid and nonassessable, and were
issued in compliance with all applicable Federal and state securities laws. No
shares of capital stock issued by TeleSpectrum are or were, at the time of their
issuance subject to preemptive rights. There are no existing subscriptions,
options, warrants, calls, commitments, agreements, conversion rights or other
rights of any character (contingent or otherwise) to purchase or otherwise
acquire from TeleSpectrum at any time, or upon the happening of any stated
event, any shares of the capital stock of TeleSpectrum whether or not presently
issued or outstanding, except as set forth in the TeleSpectrum Schedule or as
disclosed in this Section 3.3. All of the Merger Shares and Warrant Shares have
been duly authorized and, upon issuance in accordance with this Agreement and
the terms of the Warrants, will be validly issued, fully paid and nonassessable
and will be issued in compliance with all federal and state securities laws. All
of the Merger Shares and upon issuance, the Warrant Shares, will be freely
tradable except for restrictions that may be imposed on Affiliates (as such term
is defined in Rule 144 under the Securities Act) by Rules 144 or 145 of the
Securities Act or the IDRC Stockholder Support Agreement.

This Agreement constitutes a valid and binding agreement of TeleSpectrum,
enforceable against TeleSpectrum in accordance with its terms.

     Section 3.6  Conflict with Other Agreements; Approvals.  The execution
and delivery of this Agreement by TeleSpectrum does not, and the consummation of
the transactions contemplated hereby will not, (i) violate or conflict with the
Certificate of Incorporation or Bylaws of TeleSpectrum or the comparable
organizational documents of any TeleSpectrum Subsidiary, (ii) constitute a
breach or default (or an event that with notice or lapse of time or both would
become a breach or default) or give rise to any Lien, third party right of
termination, cancellation, material modification or acceleration, or loss of any

Subsidiaries or any of their properties or assets, except, in the case of
clauses (ii) and (iii), for any such breaches, defaults, Liens, third party
rights, cancellations, modifications, accelerations or losses of benefits,
conflicts or violations which would not have a TeleSpectrum Material Adverse
Effect and do not impair the ability of the TeleSpectrum to perform its
obligations under this Agreement or prevent or delay the consummation of any of
the transactions contemplated hereby.

     Section 3.7  Governmental Consents and Approvals. Except as set forth
in the TeleSpectrum Schedule, neither the execution and delivery of this
Agreement by TeleSpectrum nor the consummation by TeleSpectrum of the
transactions contemplated hereby will require any consent, approval, order,
authorization, or permit of, or filing with or notification to, any Governmental

     Section 3.8  SEC Reports.  TeleSpectrum has filed all required forms,
reports and documents with the SEC since September 30, 1996 (collectively, the
"TeleSpectrum's SEC Reports"), including TeleSpectrum's Annual Report on Form
- ---------------------------                                                  
10-K for the year ended December 31, 1997 and TeleSpectrum's Quarterly Reports
on Form 10-Q for the fiscal quarters ended March 31, 1998, June 30, 1998 and
September 30, 1998.  TeleSpectrum's SEC Reports have complied in all material
respects with all applicable requirements of the Securities Act and the Exchange
Act.  As of their respective dates, none of TeleSpectrum's SEC Reports,
including any financial statements or schedules included or incorporated by
reference therein, contained any untrue statement of a material fact or omitted
to state a material fact required to be stated or incorporated by reference
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.  TeleSpectrum has
heretofore delivered or made available to IDRC, in the form filed with the SEC,
all of TeleSpectrum's SEC Reports.

     Section 3.9  Financial Statements.  The (a) consolidated balance sheets
of TeleSpectrum and the TeleSpectrum Subsidiaries at December 31, 1997 and 1996
and the related consolidated statements of operations, stockholders' equity and
cash flows for the year ended December 31, 1997 and for the period from April
26, 1996 (Inception) to December 31, 1996, together with the notes thereto,
audited by Arthur Andersen LLP; and (b) unaudited consolidated balance sheets of
TeleSpectrum and the TeleSpectrum Subsidiaries at September 30, 1998 and 1997
and the related consolidated statements of operations, stockholders' equity and
cash flows for the nine-month periods ended September 30, 1998 and 1997,  have

                                     -23-
<PAGE>
 
been prepared in accordance with GAAP consistently applied throughout the
periods involved (except as may be indicated in the notes therein).  Such
balance sheets, including the related notes, fairly present, in all material
respects, the consolidated financial position, assets and liabilities (whether
accrued, absolute, contingent or otherwise) of TeleSpectrum and the TeleSpectrum
Subsidiaries at the dates indicated and such consolidated statements of
operations, stockholders' equity and cash flows fairly present the consolidated
results of operations, stockholders' equity and cash flows of TeleSpectrum and
the TeleSpectrum Subsidiaries for the periods indicated (except that for the
absence of notes with respect to the unaudited financial statements).  The
unaudited consolidated financial statements as of and for the nine-month period
ending September 30, 1998 contain all adjustments, which are solely of a normal
recurring nature, necessary to present, in all material respects, fairly the
consolidated financial position at September 30, 1998, and the results of
operations, stockholders' equity and cash flows for the nine-month period then
ended.  (The unaudited consolidated balance sheet of TeleSpectrum and the
TeleSpectrum Subsidiaries at September 30, 1998 described above is referred to
herein as the "TeleSpectrum Balance Sheet.")
               --------------------------

TeleSpectrum Schedule discloses as of the date hereof all indebtedness for money
borrowed of TeleSpectrum or any TeleSpectrum  Subsidiary including the payee,

loan, the interest rate and the maturity date. Neither TeleSpectrum nor any
TeleSpectrum Subsidiaries have any material indebtedness, liability or

unasserted, contingent or otherwise) except (i) as and to the extent reflected,
reserved against or otherwise disclosed on the TeleSpectrum Balance Sheet or the
TeleSpectrum Schedule, (ii) for liabilities and obligations incurred subsequent

under any Contracts of TeleSpectrum.

     Section 3.12  Contracts.  All contracts, documents, instruments or
arrangements that are of a nature required to be filed as an exhibit to the
TeleSpectrum SEC Reports under the Exchange Act (the "TeleSpectrum SEC
                                                      ----------------
Contracts") have been filed as an exhibit thereto.  All TeleSpectrum SEC
Contracts are valid and binding obligations of TeleSpectrum enforceable against
TeleSpectrum in accordance with their terms.  None of TeleSpectrum, the
TeleSpectrum Subsidiaries nor, to TeleSpectrum's knowledge, any other parties,
have violated any provisions of, or committed or failed to perform any act which
with notice, lapse of time or both would constitute a default under the
provisions of, any TeleSpectrum SEC Contract, the termination or violation of
which, or the default under which, would reasonably be expected to have a
TeleSpectrum Material Adverse Effect.

     Section 3.13  Absence of Litigation; Claims.    Except as set forth in
the TeleSpectrum Schedule, there are no claims, actions, suits, proceedings or
investigations pending or, to the knowledge of TeleSpectrum, threatened against
TeleSpectrum or any of the TeleSpectrum Subsidiaries, or any properties or
rights of TeleSpectrum or any of the TeleSpectrum Subsidiaries, or with respect
to which any director, officer, employee or agent is or may be entitled to claim
indemnification from TeleSpectrum or any TeleSpectrum Subsidiary pursuant to
TeleSpectrum's certificate of incorporation or Bylaws or pursuant to any similar
organizational documents of any TeleSpectrum Subsidiary or under any
indemnification agreements to which TeleSpectrum or any TeleSpectrum Subsidiary
is a party before any Governmental Entity, nor is there any judgement, decree,
injunction, rule or order of any Governmental Entity outstanding against
TeleSpectrum or any of the TeleSpectrum Subsidiaries.

     Section 3.14  Tax Matters.  The representations and warranties
contained in the TeleSpectrum Tax Certificate (as defined in Section 4.14
hereof) are true and correct in all material respects.  Neither TeleSpectrum
nor, to the knowledge of TeleSpectrum, any of its affiliates has taken or agreed
to take any action that would prevent the Merger from constituting a
reorganization qualifying under the provisions of Section 368(a) of the Code or
make untrue any presentation or warranty contained in the TeleSpectrum Tax
Certificate.

     Section 3.15    Affiliates.  Except for the persons listed in the

fact or omit to state any material fact required to be stated in the
Registration Statement or necessary in order to make the statements in the
Registration Statement not misleading. The information supplied by TeleSpectrum
for inclusion in the Proxy Statement to be sent to the stockholders of
TeleSpectrum in connection with the TeleSpectrum Stockholders Meeting shall not,
at the time the Proxy Statement is first mailed to stockholders or at the time
of the TeleSpectrum Stockholders Meeting, contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements made, in light of the circumstances under which they were made, not
misleading or omit to state any material fact necessary to correct any statement
in any earlier communication with respect to the solicitation of proxies for the
TeleSpectrum Stockholders Meeting which has become false or misleading.

     Section 3.17  State Takeover Statutes.  The TeleSpectrum Board has
approved the Merger and this Agreement and such approval is sufficient to render
inapplicable to the Merger and this Agreement the provisions of Section 203 of
the DGCL to the extent, if any, that such section is applicable to the Merger
and this Agreement.  To TeleSpectrum's knowledge, no other state takeover
statute or similar statute or regulation applies to or purports to apply to the
Merger or this Agreement.

     Section 3.18  Board Action.  The Board of Directors of TeleSpectrum,
has unanimously determined that the transactions contemplated by this Agreement
are in the best interests of TeleSpectrum and its stockholders and has resolved
to recommend to such stockholders that they vote in favor thereof. TeleSpectrum

executive officers that each such person intends to vote his shares of
TeleSpectrum Common Stock in favor of the approval and adoption of this
Agreement.

     Section 3.19  Brokers and Finders.  Neither TeleSpectrum nor any of its

the terms of an engagement letter, a copy of which has previously been furnished
to IDRC.

to IDRC copies of all documents listed or referred to in the TeleSpectrum
Schedule hereto or referred to herein.  Such copies are true and complete and

currently in effect thereunder.  No representation or warranty by TeleSpectrum
in this Agreement nor the TeleSpectrum Schedule contains or will contain any
untrue statement of a material fact or omits or will omit to state a material
fact required to be stated herein or therein or necessary to make any statement
herein or therein not misleading.

are the subject of the Claim Notice.  If TeleSpectrum and the Indemnified IDRC
Party are unable to agree on any settlement or compromise, then such claim shall
be resolved in accordance with Section 7.5(d) hereof.

          (c)  If TeleSpectrum shall be obligated to indemnify an Indemnified
IDRC Party hereunder, TeleSpectrum shall pay to such Indemnified IDRC Party
within 5 business days after the amount to which such Indemnified IDRC Party
shall be entitled is finally determined.

          (d)  If there shall be a dispute as to any claim, cause of action or
dispute, the amount or manner of indemnification by TeleSpectrum under this
Article VII, TeleSpectrum and the Indemnified IDRC Party shall seek to resolve
such dispute through negotiations and, if such dispute is not resolved within
twenty days, the parties shall submit the resolution of any claim, cause of
action or dispute to expedited, binding arbitration pursuant to this Section.
Any claim, cause of action or dispute between the parties arising under this
Agreement submitted to arbitration under this Section ("Arbitrated Disputes")
                                                        -------------------  
shall be resolved by binding arbitration administered by the American
Arbitration Association ("AAA") in Wilmington, Delaware, and, except as
                          ---                                          
expressly provided in this Agreement, shall be conducted in accordance with the
Expedited Procedures under the Commercial Arbitration Rules of the AAA, as such
rules may be amended from time to time (the "Rules").  The hearing locale shall
                                             -----                             
be Wilmington, Delaware.  The hearing shall be before a panel of three
arbitrators (the "Arbitrators"), one of whom shall be selected by the
Stockholders' Representative, one of whom shall be selected by TeleSpectrum, and
the third of whom shall be selected by the other two arbitrators.  The
Arbitrators' decision (the "Decision") shall be binding, and the prevailing
                            --------                                       
party may enforce the Decision in any court of competent jurisdiction.  The
parties shall use their best efforts to cooperate with each other in causing the
arbitration to be held in as efficient and expeditious a manner as practicable,
including, but not limited to, providing such documents and making available
such of their personnel as the Arbitrators may request, so that the Decision may
be reached timely.  The Arbitrators shall take into account the parties' stated
goal of expedited proceedings in determining whether to authorize discovery and,
if so, the scope of permissible discovery and other hearing and pre-hearing
procedures.  The authority of the Arbitrators shall be limited to deciding
liability for, and the proper amount of, any such claim, cause of action or
dispute, and the Arbitrators shall have no authority to award punitive damages.
The Arbitrators shall have such powers and establish such procedures as are
provided for in the Rules, so long as such powers and procedures are consistent
with this Section and are

                                     -44-
<PAGE>
 
necessary to resolve the Arbitrated Dispute within the time periods specified in
this Agreement. The Arbitrators shall render a Decision within 30 business days
after being appointed to serve as Arbitrators unless the parties otherwise agree
in writing or the Arbitrators make a finding that a party has carried the burden
of showing good cause for a longer period. The IDRC Indemnified Parties, on the
one hand, and TeleSpectrum on the other hand, shall pay its own expenses of
arbitration and the expenses of the Arbitrators shall be equally shared;
provided, however, that if in the opinion of the Arbitrators any claim or
defense or objection thereto by either party is unreasonable, the Arbitrators
may assess, as part of the award, all or any part of the arbitration expenses
(including reasonable attorneys' fees) of the other party and of the Arbitrators
against the party raising such unreasonable claim, defense or objection.

     Section VII.6  Limitations on Indemnification.  Notwithstanding any other
provision of this Section 7, (i) no Indemnified Party shall be entitled to
indemnification hereunder for Damages arising out of or based upon any
inaccuracy in or breach of any representation or warranty or breach of covenant
made in or pursuant to this Agreement until the aggregate of all Damages
incurred by the Indemnified Parties in the group to which such Indemnified Party
belongs (either Indemnified TeleSpectrum Parties, as a group, or Indemnified
IDRC Parties, as a group) exceeds $250,000 (the "Deductible Amount"), and then
                                                 -----------------            
such Indemnified Party shall be entitled to indemnification for its Damages in
excess of the Deductible Amount, (ii) the stockholders of IDRC and the IDRC
Optionholders, as a group, shall not be required to indemnify the TeleSpectrum
Indemnified Parties for an aggregate amount in excess of $9,000,000 under
Section 7.2 hereof, (iii) except as set forth in the Indemnity Escrow Agreement,
the stockholders of IDRC and the IDRC Optionholders, as a group, shall not be
required to indemnify the TeleSpectrum Indemnified Parties for an aggregate
amount in excess of $3,000,000 under Section 7.3 hereof, and (iv) TeleSpectrum
shall not be required to indemnify the IDRC Indemnified Parties for an aggregate
amount in excess of $9,000,000 under Section 7.4 hereof.  Without limiting the
generality of the foregoing, any indemnification payments required to be made by
the stockholders of IDRC and the IDRC Optionholders hereunder shall be made
exclusively from the Escrow Securities held by the Escrow Agent under the
Indemnity Escrow Agreement, and TeleSpectrum shall have no recourse against any
stockholders of IDRC and the IDRC Optionholders in connection with any
indemnification claim hereunder.  In addition, the calculation of the Deductible
Amount shall include any Damages incurred by an Indemnified Party for which the
Indemnified Party would have been entitled to claim indemnification under this
Article VII with respect to a breach of representation or warranty but for such
representation or warranty being qualified by materiality.

     Section 7.7  Claims Period.  Any claim for indemnification under this
Article VII for a breach of a representation, warranty or covenant (except for
these covenants which by their context cannot be performed in full prior to the
Expiration Date) shall be made by giving notice in accordance with the Indemnity
Escrow Agreement on or before the applicable "Expiration Date."

     Section 7.8  Exclusive Remedy.  The remedies provided by Article VII shall
constitute the exclusive remedies for the matters covered hereby. In addition,
except as provided in Section 7.9, the sole recourse of any Indemnified
TeleSpectrum Party for Damages under Sections 7.2 and 7.3 shall be under the
Indemnity Escrow Agreement, and by becoming parties to this Agreement for
purposes of Section 4.20, the MDC Entities shall not thereby assume
responsibility for the accuracy or breach of any representations, warranties or
covenants included elsewhere in this Agreement, nor shall the MDC entities
assume any liability in excess of their pro rata portion of the Escrow Property.

     Section 7.9   Exception to Limitation.  Nothing herein shall be deemed
to limit or restrict in any manner any rights or remedies which any party has,
or might have, at law, in equity or otherwise, including the right to seek
general recourse, for any representation or warranty that was known to be untrue
by the maker when made with an actual intent to mislead or defraud.

     Section 7.10  Effect of Investigation.  Any claim for indemnification
shall not be invalid as a result of any investigation by or opportunity to
investigate afforded to any party, except where such party had actual current
awareness of such claim prior to the date hereof and did not provide notice to
the other party of such awareness.

                               Irrevocable Proxy

     The undersigned stockholder of TeleSpectrum Worldwide Inc., a Delaware
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints and constitutes Robert B. Hellman, Jr., Jeffrey E. Stiefler and
International Data Response Corporation, a Delaware corporation ("IDRC"), and
each of them, the attorneys and proxies of the undersigned with full power of
substitution and resubstitution, to the full extent of the undersigned's rights
with respect to (i) the issued and outstanding shares of capital stock of the
Company owned of record by the undersigned as of the date of this proxy, which
shares are specified on the final page of this proxy and (ii) any and all other
shares of capital stock of the Company which the undersigned may acquire after
the date hereof.  (The shares of the capital stock of the Company referred to in
clauses (i) and (ii) of the immediately preceding sentence are collectively
referred to as the "Subject Shares")  Upon the execution hereof, all prior
proxies given by the undersigned with respect to any of the Subject Shares are
hereby revoked, and no subsequent proxies will be given with respect to any of
the Subject Shares.

     This proxy is irrevocable, is coupled with an interest and is granted in
connection with a Stockholder Support Agreement, dated as of the date hereof,
between IDRC and the undersigned (the "Stockholder Support Agreement"), and is
granted in consideration of IDRC entering into the Agreement and Plan of Merger,
dated as of the date hereof, among IDRC, the Company and certain stockholders of
IDRC (the "Merger Agreement").  Capitalized terms used but not otherwise defined
in this proxy have the meanings ascribed to such terms in the Merger Agreement.

     The attorneys and proxies named above will be empowered, and may exercise
this proxy, to vote the Subject Shares at any time until the earlier to occur of
the valid termination of the Merger Agreement or the Effective Time at any
meeting of the stockholders of the Company, however called, or in any written
action by consent of stockholders of the Company in favor of the Merger, the
execution and delivery by the Company of the Merger Agreement and the adoption
and approval of the terms thereof and in favor of each of the other actions
contemplated by the Merger Agreement and any action required in furtherance
hereof and thereof.

     The undersigned stockholder may vote the Subject Shares on all other
matters which would reasonably be expected to delay or otherwise interfere or
prevent the consummation of the Merger.

     This proxy shall be binding upon the heirs, successors and assigns of the
undersigned (including any transferee of any of the Subject Shares).

     Any term or provision of this proxy which is invalid or unenforceable in
any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without rendering invalid or unenforceable
the remaining terms and provisions of this proxy or affecting the validity or
enforceability of any of the terms or provisions of this proxy in any other
jurisdiction.  If any 

                                      -6-
<PAGE>
 
provision of this proxy is so broad as to be unenforceable, the provision shall
be interpreted to be only so broad as is enforceable.

     This proxy shall terminate upon the earlier of the termination of the
Merger Agreement pursuant to Section 6.1 thereof or the Effective Time.

matters which would reasonably be expected to delay or otherwise interfere or
prevent the consummation of the Merger.

undersigned (including any transferee of any of the Subject Shares).

     Any term or provision of this proxy which is invalid or unenforceable in
any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of
such invalidity or unenforceability without rendering invalid or unenforceable
the remaining terms and provisions of this proxy or affecting the validity or
enforceability of any of the terms or provisions of this proxy in any other
jurisdiction.  If any provision of this proxy is so broad as to be
unenforceable, the provision shall be interpreted to be only so broad as is
enforceable.

     3.   Representations and Warranties.
          ------------------------------ 

     (1)       The Stockholder has the requisite capacity and legal right to
          execute and deliver this Agreement and the Merger Agreement and to
          consummate the transactions contemplated hereby. Each of this
          Agreement and the Merger Agreement is enforceable against the
          Stockholder in accordance with its terms.

     (2)       The Stockholder represents and warrants to TeleSpectrum that (i)
          the Stockholder is the record and beneficial owner of, and has good
          and marketable title to, the Subject Shares, (ii) the Stockholder does
          not own, of record or beneficially, any shares of capital stock of
          IDRC other than the Subject Shares 
<PAGE>
 
          and shares of IDRC Series A Preferred Stock, and (iii) the Stockholder
          has the sole right to vote, and the sole power of disposition with
          respect to, the Subject Shares, and none of the Subject Shares is
          subject to any voting trust, proxy or other agreement, arrangement or
          restriction with respect to the voting or disposition of such Subject
          Shares, except for this Agreement.

     4.   Lock-Up.  In consideration and as an inducement of TeleSpectrum's
          -------                                                          
willingness to enter into the Merger Agreement, the Stockholder agrees that,
without the prior written consent of TeleSpectrum (which consent may be withheld
for any reason), the Stockholder will not, directly or indirectly (a) offer,
sell, pledge, contract to sell (including any short sale), grant any option to
purchase or otherwise dispose of any shares of TeleSpectrum Common Stock, the
Warrants or Warrant Shares acquired by such Stockholder in connection with the
Merger or upon the exercise of any options acquired in connection with the
Merger, or (b) enter into any Hedging Transaction (as defined below) relating to
the foregoing securities (each of the foregoing classes (a) and (b) are
hereinafter referred to as a "Disposition") for a period of one year after the
                              -----------                                     
Effective Time (the "Lock-Up Period").  The foregoing restriction is expressly
                     --------------                                           
intended to preclude the Stockholder from engaging in any Hedging Transaction or
other transaction which is designed to or reasonably expected to lead to or
result in a Disposition by the Stockholder during the Lock-Up Period even if the
securities would be disposed of by someone other than the Stockholder.  "Hedging
Transaction" means any short sale (whether or not against the box) or any
purchase, sale or grant of any right (including, without limitation, any put or
call option) with respect to any security (other than a broad-based market
basket or index) that includes, relates to or derives any significant part of
its value from the shares of TeleSpectrum Common Stock; provided that the
exercise of an option or warrant to purchase shares of TeleSpectrum Common Stock
or other securities issued by TeleSpectrum or the conversion of any convertible
securities into shares of TeleSpectrum Common Stock or other securities issued
by TeleSpectrum shall not be a Hedging Transaction.  The restrictions on
Disposition of TeleSpectrum Common Stock shall not apply to any TeleSpectrum
Common Stock acquired by the Stockholder in the open market or otherwise than in
connection with the Merger.

          Without limiting the restrictions herein, any Disposition by the
Stockholder shall remain at all times subject to applicable securities laws  The
Stockholder also agrees that TeleSpectrum may cause its transfer agent to note
stop transfer instructions with respect to shares of TeleSpectrum Common Stock
beneficially owned by the Stockholder on the transfer books and records of
TeleSpectrum.

     5.   Termination.  The obligations of the Stockholder hereunder shall 
          -----------
terminate upon the earlier of the termination of the Merger Agreement pursuant
to Section 6.1 thereof or the Effective Time; provided, however, that Section 4
                                              --------  -------
shall survive for the Lock-Up Period.

     6.   Further Assurances.  Stockholder will, from time to time, promptly 
          ------------------
execute and 
<PAGE>
 
deliver, or cause to be executed and delivered, such additional or further
consents, documents and other instruments as TeleSpectrum may reasonably request
for the purpose of effectively carrying out the transactions contemplated by
this Agreement.

     7.   Successors, Assigns and Transferees Bound.  Except as provided herein,
          -----------------------------------------                             
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned by either of the parties hereto (whether by operation of law
or otherwise) without the prior written consent of the other party.  Any
successor, assignee or transferee (including a successor, assignee or transferee
as a result of the death of the Stockholder, such as an executor or heir) shall
be bound by the terms hereof, and the Stockholder shall take any and all actions
necessary to obtain the written confirmation from such successor, assignee or
transferee that it is bound by the terms hereof.

     8.   Remedies.  The Stockholder acknowledges that money damages would be 
          --------
both incalculable and an insufficient remedy for any breach of this Agreement by
it, and that any such breach would cause TeleSpectrum irreparable harm.
Accordingly, the Stockholder agrees that in the event of any breach or
threatened breach of this Agreement, TeleSpectrum, in addition to any other
remedies at law or in equity it may have, shall be entitled, without the
requirement of posting a bond or other security, to equitable relief, including
injunctive relief and specific performance.

     9.   Severability.  The invalidity or unenforceability of any provision of 
          ------------
this Agreement in any jurisdiction shall not affect the validity or
enforceability of any other provision of this Agreement in such jurisdiction, or
the validity or enforceability of any provision of this Agreement in any other
jurisdiction.

     10.  Amendment.  This Agreement may be amended only by means of a written
          ---------                                                           
instrument executed and delivered by both the Stockholder and TeleSpectrum.

     11.  Governing Law.  This Agreement shall be governed by, and construed in
          -------------                                                        
accordance in accordance with, the laws of the State of Delaware, regardless of
the laws that might otherwise govern under applicable principles of conflicts of
laws thereof.
<PAGE>
 
     12.  Counterparts.  For the convenience of the parties, this Agreement may 
          ------------
be executed in one or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same
instrument.
