such four fiscal quarters (in each case, determined, for each fiscal quarter (or portion thereof) of the four fiscal quarters ending prior to or including the Issue Date, on a pro forma basis to give effect to the consummation of the Plan, the
issuance of the Senior Notes and the consummation of the other transactions contemplated to be effected under Plan as if they had occurred at the beginning of such four quarter period adjusted for any pro forma expense and cost reductions and
related adjustments that are directly attributable to such exchange and consummation); provided, however, that (1) if DDi Capital or any of its Restricted Subsidiaries (x) has Incurred any Indebtedness since the beginning of such period that remains
outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated EBITDA and Consolidated Interest Expense for such period shall be
calculated after giving effect on a pro forma basis to such Indebtedness as if such Indebtedness had been Incurred on the first day of such period (except that in making such computation, the amount of Indebtedness under any revolving credit
facility outstanding on the date of such calculation shall be computed based on (A) the average daily balance of such Indebtedness during such four fiscal quarters or such shorter period for which such facility was outstanding or (B) if such
facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such facility to the date of such calculation) and the discharge of any other Indebtedness
repaid, repurchased, defeased or otherwise discharged with the proceeds of such new Indebtedness as if such discharge had occurred on the first day of such period, or (y) has repaid, repurchased, defeased or otherwise discharged any Indebtedness
since the beginning of the period that is no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio involves a discharge of 

  

 5 








 
Indebtedness (in each case other than Indebtedness incurred under any revolving credit facility unless such Indebtedness has been permanently repaid),
Consolidated EBITDA and Consolidated Interest Expense for such period shall be calculated after giving effect on a pro forma basis to such discharge of such Indebtedness, including with the proceeds of such new Indebtedness, as if such discharge had
occurred on the first day of such period, (2) if since the beginning of such period DDi Capital or any of its Restricted Subsidiaries shall have made any Asset Disposition or if the transaction giving rise to the need to calculate the Consolidated
Coverage Ratio is an Asset Disposition, the Consolidated EBITDA for such period shall be reduced by an amount equal to the Consolidated EBITDA (if positive) directly attributable to the assets which are the subject of such Asset Disposition for such
period or increased by an amount equal to the Consolidated EBITDA (if negative) directly attributable thereto for such period and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense
directly attributable to any Indebtedness of DDi Capital or any of its Restricted Subsidiaries repaid, repurchased, defeased or otherwise discharged with respect to DDi Capital and its continuing Restricted Subsidiaries in connection with such Asset
Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent DDi Capital and its
continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale), (3) if since the beginning of such period DDi Capital or any of its Restricted Subsidiaries (by merger or otherwise) shall have made an Investment in any
Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary) or an acquisition of assets, including any acquisition of assets occurring in connection with a transaction causing a calculation to be made hereunder, Consolidated EBITDA
and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition occurred on the first day of such period (adjusted for
any pro forma expense and cost reductions and related adjustments calculated on a basis consistent with the Securities Act, the Exchange Act and the rules and regulations promulgated thereunder) and (4) if since the beginning of such period any
Person (that subsequently became a Restricted Subsidiary or was merged with or into DDi Capital or any of its Restricted Subsidiaries since the beginning of such period) shall have made any Asset Disposition or any Investment that would have
required an adjustment pursuant to clause (2) or (3) above if made by DDi Capital or one of its Restricted Subsidiaries during such period, Consolidated EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro
forma effect thereto as if such Asset Disposition or Investment occurred on the first day of such period. For purposes of this definition, whenever pro forma effect is to be given to an acquisition of assets, the amount of income or earnings

 SECTION 102. Compliance Certificates and Opinions. 
  
 Upon any application or request by DDi Capital to the Trustee to take any action under 

  

 20 








 
any provision of this Indenture, DDi Capital and any other obligor on the Senior Notes (if applicable) shall furnish to the Trustee an Officers’
Certificate in form and substance reasonably acceptable to the Trustee stating that all conditions precedent, if any, provided for in this Indenture (including any covenant compliance with which constitutes a condition precedent) relating to the
proposed action have been complied with and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to which the
furnishing of such documents is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or opinion need be furnished. 
  
 Each certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture (including certificates provided pursuant to Section 1016(a)) shall include: 
  
 (1) a statement that each individual signing such certificate or opinion has read such covenant or condition and the definitions herein relating thereto;

  
 (2) a brief statement as to the nature and scope of the
examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; 
  
 (3) a statement that, in the opinion of each such individual or such firm, he or it has made such examination or investigation as is necessary to enable
him or it to express an informed opinion as to whether or not such covenant or condition has been complied with; and 
  
 (4) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with. 
  
 SECTION 103. Form of Documents Delivered to Trustee.

  
 In any case where several matters are required to be
certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. 
  
 Any certificate or opinion of an officer of DDi Capital or any other obligor
on the Senior Notes may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion
or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of DDi Capital or any other obligor on the Senior Notes stating that the information with respect to such factual matters is in the possession of DDi Capital or any other obligor on the Senior Notes unless
such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. 
  

 21 








 Where any Person is required to make, give or execute two or more applications, requests, consents,
certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument. 
  
 SECTION 104. Acts of Holders. 
  
 (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective
when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to DDi Capital. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as
the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and DDi Capital, if made in the manner provided in this Section 104. 
  
 (b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized
by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the
Trustee deems sufficient. 
  
 (c) The principal amount and serial
numbers of Senior Notes held by any Person, and the date of holding the same, shall be proved by the Note Register. 
  
 (d) If DDi Capital shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, DDi Capital may, at
its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but DDi Capital shall have no
obligation to do so. Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such
record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Senior Notes have authorized or agreed
or consented to such request, demand, authorization, direction, notice, 

  

 22 








 
consent, waiver or other Act, and for that purpose the outstanding Senior Notes shall be computed as of such record date; provided that no such
authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 
  
 (e) Any request, demand, authorization, direction, notice, consent, waiver or
other Act of the Holder of any Senior Note shall bind every future Holder of the same Senior Note and the Holder of every Senior Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof (including in
accordance with Section 308) in respect of anything done, omitted or suffered to be done by the Trustee, any Paying Agent or DDi Capital in reliance thereon, whether or not notation of such action is made upon such Senior Note. 
  
 SECTION 105. Notices, Etc., to Trustee and DDi Capital.

  
 Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 
  
 (1) the Trustee by any Holder or by DDi Capital or any other obligor on the Senior Notes shall be sufficient for every purpose hereunder if made, given,
furnished or delivered in writing and mailed, first-class postage prepaid, or delivered by recognized overnight courier, to or with the Trustee and received at its Corporate Trust Office, Attention: Corporate Trust Administration. 
  
 (2) DDi Capital by the Trustee or by any Holder shall be sufficient for every
purpose hereunder (unless otherwise herein expressly provided) if made, given, furnished or delivered, in writing, or mailed, first-class postage prepaid, or delivered by recognized overnight courier, to DDi Capital addressed to it and received at
the address of its principal office specified in the first paragraph of this Indenture, or at any other address previously furnished in writing to the Trustee by DDi Capital. 
  
 SECTION 106. Notice to Holders; Waiver. 
  
 Where this Indenture provides for notice of any event to Holders by DDi Capital or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder, at his address as it appears in the Note Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. Neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice
mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by such Holder, whether or not such Holder actually receives such notice. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such waiver. 
  

 23 








 In case by reason of the suspension of or irregularities in regular mail service or by reason of any
other cause, it shall be impracticable to mail notice of any event to Holders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall
be deemed to be a sufficient giving of such notice for every purpose hereunder. 
  
 If DDi Capital mails any notice or communication to any Holder, it shall mail a copy to the Trustee at the same time. 
  
 SECTION 107. Effect of Headings and Table of Contents.

and Assigns. 
  
 All covenants and agreements in this Indenture
by DDi Capital shall bind its successors and assigns, whether so expressed or not. 
  
 SECTION 109. Separability Clause. 
  
 In case any provision in this Indenture or in the Senior Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby. 
  
 SECTION 110. Benefits of Indenture. 
  
 Nothing in this Indenture or in the Senior Notes, express or implied, shall give to any Person, (other than the parties hereto, any agent and their
successors hereunder and each of the Holders) any benefit or any legal or equitable right, remedy or claim under this Indenture. 
  
 SECTION 111. Governing Law. 
  
 THIS INDENTURE AND THE SENIOR NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK EXCLUDING (TO THE GREATEST
EXTENT PERMISSIBLE BY LAW) ANY RULE OF LAW THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK. THIS INDENTURE SHALL BE SUBJECT TO THE PROVISIONS OF THE TIA THAT ARE REQUIRED TO BE PART OF THIS INDENTURE
IN ACCORDANCE WITH THE PROVISIONS OF THE TIA AND SHALL, TO THE EXTENT APPLICABLE, BE GOVERNED BY SUCH PROVISIONS. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE U.S. FEDERAL COURTS, IN
EACH CASE SITTING IN THE BOROUGH OF MANHATTAN, AND WAIVES ANY OBJECTION AS TO VENUE OR FORUM NON CONVENIENS. 
  

 24 








 SECTION 112. Legal Holidays. 
  
 In any case where any Interest Payment Date, any date established for
payment of Defaulted Interest pursuant to Section 309 or Redemption Date or Stated Maturity of any Senior Note shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Senior Notes) payment of principal or
interest need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or date established for payment of Defaulted Interest pursuant to Section 309,
Redemption Date, or at the Stated Maturity; provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or date established for payment of Defaulted Interest pursuant to Section 309, or Stated
Maturity, as the case may be, to the next succeeding Business Day. 
  
 SECTION 113. No Personal Liability of Directors, Officers, Employees, Stockholders or Incorporators. 
  
 No director, officer, employee, incorporator or stockholders, as such, of DDi Capital shall have any liability for any obligations of DDi Capital under
the Senior Notes, this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creations. Each Holder by accepting a Senior Note waives and releases all such liability. Such waiver and release are part of the
consideration for the issuance of the Senior Notes.

signed in any number of counterparts each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Indenture.

with respect to their rights under this Indenture or the Senior Notes. DDi Capital, the Trustee, the Note Registrar and anyone else shall have the protection of TIA § 312(c).

 [FORM OF REVERSE SIDE
OF SENIOR NOTE] 
 16% Senior Accreting Note due 2009 
  

1. Interest 
  
 DDi Capital Corp., a California corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein
called “DDi Capital”), promises to pay interest on the Accreted Value (as hereinafter defined) of this Senior Note in the manner described below. 
  
 Interest shall be payable on this Senior Note quarterly in arrears to the Holder of record hereof at the close of business on the December 1, March 1,
June 1 and September 1 (the “Record Date”) next preceding (i) the interest payment date on December 15, March 15, June 15 and September 15 of each year, commencing March 15, 2004, (ii) any date of redemption, purchase or repurchase in part
or in full of all or any portion of this Senior Note and (iii) the Maturity Date of this Senior Note (each such date, an “Interest Payment Date”). On each such Interest Payment Date prior to the Irrevocable Cash Interest Election Date (as
defined below), except as set forth in the immediately following paragraph, DDi Capital shall have the option of paying interest on the then outstanding Accreted Value of this Senior Note from and including the most recent date through which
interest has been paid, or, if no interest has been paid, from December 12, 2003, through but excluding such Interest Payment Date, at a rate of (i) sixteen percent (16%) per annum by accreting in value the outstanding Accreted Value of this Senior
Note by the amount of such interest due, or (ii) fourteen percent (14%) per annum in cash. Unless DDi Capital notifies the Trustee in the Interest Payment Certificate described below that it desires or is required to pay all such interest in cash,
all such interest shall be deemed to be paid by accretion of the Accreted Value of this Senior Note in the manner set forth above. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. 
  
 On the Record Date for each Interest Payment Date (or the next succeeding
Business Day, if such Record Date is not a Business Day), DDi Capital shall provide the Trustee with an Officers’ Certificate in accordance with the terms of Section 301 of the Indenture (each, an “Interest Payment Certificate”). In
the event that the Leverage Ratio of DDi Capital shown in such Interest Payment Certificate or any other Interest Payment Certificate delivered in respect of any prior record date is less than or equal to 2.5 to 1.0, DDi Capital shall be required to
pay the entire interest due on this Senior Note on such Interest Payment Date and on each subsequent 

  

 30 








 
Interest Payment Date in cash as set forth in the immediately preceding paragraph. Without limiting the foregoing, in the event that DDi Capital or any of
its Affiliates has made or is required to have made any payment to the holders of the Senior Secured Indebtedness from Excess Cash since the most recent prior Interest Payment Date, DDi Capital shall be required to pay the entire interest due on
this Senior Note on the next succeeding Interest Payment Date only in cash as set forth in the immediately preceding paragraph. 
  
 On or prior to any Record Date, DDi Capital may notify the Trustee that it irrevocably elects to pay interest due on all subsequent Interest Payment Dates
in cash. Following such notification date (the “Irrevocable Cash Interest Election Date”), all interest due on each subsequent Interest Payment Date on the then outstanding Accreted Value of this Senior Note shall be payable in cash as set
forth in the first paragraph of this Section 1. 
  
 The
“Accreted Value” of this Senior Note equals, as of any date of determination, the sum of (a) the Initial Principal Amount of this Senior Note on the Issue Date, plus (b) the amount of interest on this Senior Note which has been accreted
thereto on each Interest Payment Date on or prior to such date in accordance with the Indenture. 
  
 2. Method of Payment 
  
 By at least 10:00 a.m. (New York City time) on the date on which any principal of or cash interest on the Senior Notes is due and payable, DDi Capital
shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal and/or interest. DDi Capital will pay interest (except defaulted interest) in the manner set forth in Section 1 to the Persons who are registered
Holders of Senior Notes at the close of business on the Record Date with respect to such Interest Payment Date even if the Senior Notes are cancelled, repurchased or redeemed after such Record Date and on or before such Interest Payment Date. DDi
Capital will pay principal and cash interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, DDi Capital may pay cash interest by check payable in such money. It may mail an
interest check to a Holder’s registered address. 
  
 3. Trustee, Paying Agent and Registrar 
  
 Initially,
Wilmington Trust Company, a Delaware banking corporation and trust company (“Trustee”), will act as Trustee, Paying Agent and Registrar. DDi Capital may appoint and change any Paying Agent, Registrar or co-registrar without notice to any
Noteholder. DDi Capital or any of its domestically incorporated Wholly-Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar. 
  
 4. Indenture 
  
 DDi Capital issued the Senior Notes under an Indenture dated as of December 12, 2003 (as it may be amended or supplemented from time to time in accordance
with the terms thereof, the “Indenture”), between DDi Capital and the Trustee. The terms of this Senior Note include those stated in the Indenture and those made part of the Indenture by reference to the Trust 

  

 31 








 
Indenture Act of 1939 (15 U.S.C. §§77aaa-77bbbb) (the “TIA”). Capitalized terms used herein and not defined herein have the meanings
ascribed thereto in the Indenture. The Senior Notes are subject to all such terms, and Noteholders are referred to the Indenture and the TIA for a statement of those terms. 
  
 The Senior Notes are unsecured senior obligations of DDi Capital limited to an aggregate Accreted Value equal to the Initial
Principal Amount of $17,656,000 plus interest thereon that is accreted thereto on any Interest Payment Date in accordance with the terms of this Note and the Indenture (subject to Section 308 of the Indenture). The Indenture imposes certain
limitations, among other things, on the Incurrence of Indebtedness by DDi Capital and its Restricted Subsidiaries, the payment of dividends on, and the purchase or redemption of, Capital Stock of DDi Capital and its Restricted Subsidiaries, the sale
or transfer of assets and Capital Stock of Restricted Subsidiaries of DDi Capital, investments of DDi Capital and its Restricted Subsidiaries and transactions with Affiliates. In addition, the Indenture limits the ability of DDi Capital and its
Subsidiaries to restrict distributions and dividends from Restricted Subsidiaries. 
  
 5. Optional Redemption; Purchase Offer Upon Certain Asset Dispositions 
  
 The Senior Notes will be redeemable at the option of DDi Capital in whole, but not in part, at any time prior to the
Maturity Date of the Senior Notes, upon not less than 30 nor more than 60 days’ prior notice mailed by first class mail to each Holder’s registered address, at 100% of the aggregate Accreted Value of the Senior Notes plus accrued and
unpaid interest to the Redemption Date (subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date). In addition, DDi Capital will be required in certain circumstances to offer
to purchase Senior Notes in whole or in part following an Asset Disposition in accordance with Section 1013. 
  
 6. Notice of Redemption 
  
 Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Senior Notes at his registered
address. If money sufficient to pay the redemption price of and accrued and unpaid interest on all Senior Notes on the Redemption Date is deposited with the Paying Agent on or before the Redemption Date and certain other conditions are satisfied, on
and after such date interest ceases to accrue on the Senior Notes. 
  
 7. Put Provisions 
  
 Upon the
occurrence of a Change Control, unless DDi Capital shall have exercised its right to redeem the Senior Notes as described under “Optional Redemption; Purchase Offer Upon Certain Asset Dispositions” above, each holder will have the right to
require DDi Capital to repurchase all or any part of such Holder’s Senior Notes at a purchase price in cash equal to 100% of the Accreted Value thereof plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of
Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date). 
  

 32 








 8. Denominations; Transfer; Exchange 
  
 The Senior Notes are in registered form without coupons in denominations of
Initial Principal Amount or Accreted Value (as applicable) of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Senior Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of (i) any Senior Note selected for redemption (except, in the
case of a Senior Note to be redeemed in part, the portion of the Senior Note not to be redeemed) for a period beginning 15 days before a selection of Senior Notes to be redeemed and ending on the date of such selection or (ii) any Senior Notes for a
period beginning 15 days before an interest payment date and ending on such interest payment date. 
  
 9. Persons Deemed Owners 
  
 The registered holder of this Senior Note may be treated as the owner of it for all purposes. 
  
 10. Unclaimed Money 
  
 If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent shall pay the money back to DDi Capital at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to DDi Capital and not to the
Trustee for payment. 
  
 11. Defeasance

  
 Subject to certain conditions set forth in the Indenture, DDi
Capital at any time may terminate some or all of its obligations under the Senior Notes and the Indenture if DDi Capital deposits with the Trustee money or U.S. Government Obligations for the payment of Accreted Value and interest on the Senior
Notes to redemption or maturity, as the case may be. DDi Capital in its sole discretion can defease the Senior Notes. 
  
 12. Amendment, Waiver 
  
 Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Senior Notes may be amended with the written consent of the Holders of
at least a majority in Accreted Value of the Senior Notes then outstanding and (ii) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in Accreted Value of the outstanding Senior
Notes. Without the consent of any Noteholder, DDi Capital and the Trustee may amend the Indenture or the Senior Notes to cure any ambiguity, omission, defect or inconsistency, or to comply with Article 8 of the Indenture, or to provide for
uncertificated Senior Notes in addition to or in place of certificated Senior Notes or to add guarantees with respect to the Senior Notes or to secure the Senior Notes, or to add addition covenants or surrender rights and powers conferred on DDi
Capital, or to comply with any request of the SEC in connection with qualifying the Indenture under the TIA, or to make any change that does not adversely affect the rights of any Noteholder. 
  

 33 








 13. Defaults and Remedies 
  
 Under the Indenture, Events of Default include (i) a default in any payment of interest on any Senior Note when due,
continued for 30 days, (ii) a default in the payment of principal of any Senior Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise, (iii) the failure by DDi Capital to comply for
30 days with its obligations under Article 8 of the Indenture, or Sections 1006, 1007, 1008, 1009, 1010, 1011, 1012, 1013, 1014 or 1015 of the Indenture (in each case, other than a failure to purchase Senior Notes which shall constitute an Event of
Default under clause (ii) above), (iv) the failure by DDi Capital to comply for 60 days after notice with its other agreements contained in the Indenture, (v) the failure by DDi Capital or any Restricted Subsidiary to pay any Indebtedness within any
applicable grace period after final maturity or the acceleration of any such Indebtedness by the holders thereof because of a default and if the total amount of such Indebtedness unpaid or accelerated exceeds $3.75 million, (vi) certain events of
bankruptcy, insolvency or reorganization of DDi Capital or a Significant Subsidiary or (vii) the rendering of any judgment or decree for the payment of money in an amount in excess of $3.75 million against DDi Capital or a Significant Subsidiary and
such judgment or decree remains undischarged or unstayed for a period of 60 days after such judgment or decree becomes final and non-appealable and is not discharged, waived or stayed. If a default occurs and is continuing it will not be deemed an
Event of Default until the Trustee or the Holders of at least 25% in Accreted Value of the outstanding Senior Notes notify DDi Capital of the default and DDi Capital does not cure such defect within the time specified in clauses (iii) and (iv)
above. Certain events of bankruptcy or insolvency are Events of Default which will result in the Senior Notes being due and payable immediately upon the occurrence of such Events of Default. 
  
 If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in Accreted Value of the outstanding Senior Notes by notice to DDi Capital and the Trustee may declare the Accreted Value of and accrued and unpaid interest, if any, on all the Senior Notes to be due and payable immediately. Upon
such a declaration, such Accreted Value and accrued and unpaid interest shall be due and payable immediately in cash. Under certain circumstances, the holders of a majority in Accreted Value of the outstanding Senior Notes may rescind any such
acceleration with respect to the Senior Notes and its consequences. 
  
 Noteholders may not enforce the Indenture or the Senior Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Senior Notes unless it receives reasonable indemnity or security. Subject to certain
limitations, Holders of a majority in Accreted Value of the Senior Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Noteholders notice of any continuing Default or Event of Default (except a Default
or Event of Default in payment of Accreted Value or interest that is required to be paid in cash) if it determines that withholding notice is in their interest. 
  

14. Trustee Dealings with DDi Capital 
  
 Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in 

  

 34 








 
its individual or any other capacity, may become the owner or pledgee of Senior Notes and may otherwise deal with and collect obligations owed to it by DDi
Capital or its affiliates and may otherwise deal with DDi Capital or its affiliates with the same rights it would have if it were not Trustee. 
  
 15. No Recourse Against Others 
  
 A director, officer, employee or stockholder, as such, of DDi Capital shall not have any liability for any obligations of DDi Capital under the Senior
Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Senior Note, each Noteholder waives and releases all such liability. The waiver and release are part of the
consideration for the issue of the Senior Notes. 
  
 16. Authentication 
  
 This Senior Note shall not be
valid until an authorized signatory of the Trustee (or an authenticating agent acting on its behalf) manually signs the certificate of authentication on the other side of this Senior Note. 
  
 17. Abbreviations 
  
 Customary abbreviations may be used in the name of a Noteholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act). 
  
 18. CUSIP Numbers 
  
 Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, DDi Capital has caused CUSIP numbers to be printed on the Senior Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Noteholders. No representation is made as to
the accuracy of such numbers either as printed on the Senior Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

 ARTICLE THREE. THE SENIOR NOTES 
  
 SECTION 301. Title and Terms. 
  
 The Initial Principal Amount of Senior Notes which may be authenticated and delivered under this Indenture is limited to
$17,656,000, except for Senior Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Senior Notes pursuant to Section 304, 305, 306, 308, 906, 1012, 1013 or 1108. The Initial Principal Amount of
the Senior Notes will accrete as described below. 
  
 The Senior
Notes shall be known and designated as the “16% Senior Accreting Notes due 2009” of DDi Capital. The Senior Notes have a Stated Maturity of January 1, 2009. 
  
 Interest shall be payable on the Senior Notes quarterly in arrears to the Holders of record thereof on the Record Date for
each applicable Interest Payment Date in the manner set forth in this paragraph. On each such Interest Payment Date prior to the Irrevocable Cash Interest Election Date, except as set forth in the immediately following paragraph, DDi Capital shall
have the option of paying interest on the then outstanding Accreted Value of the Senior Notes from and including the most recent date through which interest has been paid, or, if no interest has been paid, from the Issue Date, through but excluding
such Interest Payment Date, at a rate of (i) sixteen percent (16%) per annum by accreting in value the outstanding Accreted Value of the Senior Notes by the amount of such interest due, or (ii) fourteen percent (14%) per annum in cash. Unless DDi
Capital notifies the Trustee in the Interest Payment Certificate that it desires or is required to pay all such interest in cash, all such interest shall be deemed to be paid by accretion of the Accreted Value of the Senior Notes in the manner set
forth above. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Interest on any overdue principal or interest (to the extent lawful) shall be payable on demand. 
  
 On the Record Date for each Interest Payment Date (or the next succeeding
Business Day, if such record date is not a Business Day), DDi Capital shall provide the Trustee with an Officers’ Certificate in the form attached hereto as Exhibit 301 (each, an “Interest Payment Certificate”). In the event that the
Leverage Ratio of DDi Capital shown in such Interest Payment Certificate or any other Interest Payment Certificate delivered in respect of any prior record date is less than or equal to 2.5 to 1.0, DDi Capital shall be required to pay the entire
interest due on the Senior Notes on such Interest Payment Date and on each subsequent Interest Payment Date in cash as set forth in the immediately preceding paragraph. Without limiting the foregoing, in the event that DDi Capital or any of its
Affiliates has made or is required to have made any payment to the holders of the Senior Secured Indebtedness from Excess Cash since the most recent prior Interest Payment Date, DDi Capital shall be required to pay the entire interest due on the
Senior Notes on the next succeeding Interest Payment Date only in cash as set forth in the immediately preceding paragraph. 
  
 On or prior to any Record Date, DDi Capital may notify the Trustee that it irrevocably elects to pay interest due on all subsequent Interest Payment Dates
in cash. Following the Irrevocable Cash Interest Election Date, all interest due on each subsequent Interest Payment Date on the then outstanding Accreted Value of this Senior Note shall be payable in cash as set forth in the first paragraph of this
Section 301. 
  

 40 








 The Accreted Value and cash interest on the Senior Notes shall be payable at the office or agency of DDi
Capital maintained for such purpose in The City of New York, or at such other office or agency of DDi Capital as may be maintained for such purpose; provided, however, that, at the option of DDi Capital, cash interest may be paid by check mailed to
addresses of the Persons entitled thereto as such addresses shall appear on the Note Register. 
  
 Holders shall have the right to require DDi Capital to purchase their Senior Notes, in whole or in part, in the event of a Change of Control pursuant to Section 1012. 
  
 The Senior Notes shall be subject to repurchase, in whole or in part, by DDi
Capital pursuant to an Asset Disposition as provided in Section 1013. 
  
 The Senior Notes shall be redeemable in whole, but not in part, as provided in Article Eleven and in the Senior Notes. 
  
 SECTION 302. Denominations. 
  
 The Senior Notes shall be issuable only in fully registered form, without coupons, and only in denominations of Initial Principal Amount of $1,000 and any
integral multiple thereof. 
  
 SECTION 303.
Execution, Authentication, Delivery and Dating. 
  
 The Senior
Notes shall be executed on behalf of DDi Capital by two Officers, of which at least one Officer shall be the President or the Chief Financial Officer of DDi Capital. The signature of any Officer on the Senior Notes may be manual or facsimile
signatures of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Senior Notes. 
  
 Senior Notes bearing the manual or facsimile signatures of individuals who were at any time the proper officers of DDi Capital shall bind DDi Capital,
notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Senior Notes or did not hold such offices at the date of such Senior Notes. 
  
 At any time and from time to time after the execution and delivery of this
Indenture, DDi Capital may deliver Senior Notes executed by DDi Capital to the Trustee for authentication, together with an Order for the authentication and delivery of such Senior Notes (the “Authentication Order”), and the Trustee in
accordance with such Authentication Order shall authenticate and deliver such Senior Notes directing the Trustee to authenticate the Senior Notes and certifying that all conditions precedent to the issuance of Senior Notes, if any, contained herein
have been fully complied with, and the Trustee in accordance with such Authentication Order shall authenticate and deliver such Senior Notes. The Trustee shall be entitled to receive an Officers’ Certificate and an Opinion of Counsel of DDi
Capital that it may reasonably request in connection with such authentication of Senior Notes. Such order shall specify the amount of Senior Notes to be authenticated and the date on which the original issue of Senior Notes is to be authenticated.

  

 41 








 Each Senior Note shall be dated the date of its authentication. 
  
 No Senior Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Senior Note a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such
certificate upon any Senior Note shall be conclusive evidence, and the only evidence, that such Senior Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. 
  
 In case DDi Capital, pursuant to Article Eight, shall be consolidated or
merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation, or surviving such merger,
or into which DDi Capital shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as aforesaid, shall have executed an indenture supplemental hereto with the Trustee pursuant to Article
Eight, any of the Senior Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other Senior Notes
executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Senior Notes surrendered for such exchange and of like Initial Principal Amount and
Accreted Value; and the Trustee, upon DDi Capital’s request of the successor Person, shall authenticate and deliver Senior Notes as specified in such request for the purpose of such exchange. If Senior Notes shall at any time be authenticated
and delivered in any new name of a successor Person pursuant to this Section 303 in exchange or substitution for or upon registration of transfer of any Senior Notes, such successor Person, at the option of the Holders but without expense to them,
shall provide for the exchange of all Senior Notes at the time outstanding for Senior Notes authenticated and delivered in such new name. 
  
 The Trustee may appoint an authenticating agent acceptable to DDi Capital to authenticate Senior Notes on behalf of the Trustee. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Senior Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the
same rights as any Note Registrar or Paying Agent to deal with DDi Capital and its Affiliates hereunder. 
  
 SECTION 304. Temporary Senior Notes. 
  
 Pending the preparation of definitive Senior Notes, DDi Capital may execute, and upon Authentication Order the Trustee shall authenticate and deliver,
temporary Senior Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination. Temporary Senior Notes shall be substantially of the tenor of the definitive Senior Notes in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Senior Notes may determine, as conclusively evidenced by their execution of such Senior Notes. 
  

 42 








 If temporary Senior Notes are issued, DDi Capital will cause definitive Senior Notes to be prepared
without unreasonable delay. After the preparation of definitive Senior Notes, the temporary Senior Notes shall be exchangeable for definitive Senior Notes upon surrender of the temporary Senior Notes at the office or agency of DDi Capital designated
for such purpose pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Senior Notes, DDi Capital shall execute and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Senior Notes of authorized denominations. Until so exchanged, the temporary Senior Notes shall in all respects be entitled to the same benefits under this Indenture as definitive Senior Notes. 
  
 SECTION 305. Registration, Registration of Transfer and
Exchange 
  
 DDi Capital shall cause to be kept at the Corporate
Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the “Note Register”) in which, subject to such
reasonable regulations as it may prescribe, DDi Capital shall provide for the registration of Senior Notes and of transfers of Senior Notes. The Note Register shall be in written form or any other form capable of being converted into written form
within a reasonable time. At all reasonable times, the Note Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as security registrar (the Trustee in such capacity, together with any successor of the
Trustee in such capacity, the “Note Registrar”) for the purpose of registering Senior Notes and transfers of Senior Notes as herein provided. 
  
 Upon surrender for registration of transfer of any Senior Note at the office or agency of DDi Capital designated pursuant to Section 1002, DDi Capital
shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Senior Notes of any authorized denomination or denominations of a like aggregate principal amount. 
  
 Furthermore, any Holder of a Global Senior Note shall, by acceptance of such
Global Senior Note, agree that transfers of beneficial interests in such Global Senior Note may be effected only through a book entry system maintained by the Holder of such Global Senior Note (or its agent) and that ownership of a beneficial
interest in the Global Senior Note shall be required to be reflected in a book entry. At the option of the Holder, Senior Notes may be exchanged for other Senior Notes of any authorized denomination of Initial Principal Amount (not less than $1,000)
and of a like aggregate Initial Principal Amount and Accreted Value, upon surrender of the Senior Notes to be exchanged at such office or agency. Whenever any Senior Notes are so surrendered for exchange, DDi Capital shall execute, and the Trustee
shall authenticate and deliver, the Senior Notes which the Holder making the exchange is entitled to receive. 
  
 All Senior Notes issued upon any registration of transfer or exchange of Senior Notes shall be the valid obligations of DDi Capital, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Senior Notes surrendered upon such registration of transfer or exchange. 
  

 43 








 Every Senior Note presented or surrendered for registration of transfer or for exchange shall (if so
required by DDi Capital or the Note Registrar) be duly endorsed, or be accompanied by a written instrument of transfer, in form satisfactory to DDi Capital and the Note Registrar, duly executed by the Holder thereof or his attorney duly authorized
in writing. 
  
 No service charge shall be made for any
registration of transfer or exchange or redemption of Senior Notes, but DDi Capital may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange
of Senior Notes, other than exchanges pursuant to Section 304, 906, 1012, 1013 or 1108, not involving any transfer. 
  
 The Register shall be in written form in the English language or in any other form including computerized records, capable of being converted into such
form within a reasonable time. 
  
 SECTION 306.
Book-Entry Provisions for Global Senior Notes. 
  
 (a) Each
Global Senior Note initially shall (i) be registered in the name of the Depositary for such Global Senior Note or the nominee of such Depositary, (ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear a legend as set forth
in Section 202. 
  
 Members of, or participants in, the Depositary
(“Agent Members”) shall have no rights under this Indenture with respect to any Global Senior Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Senior Note, and the Depositary may be treated
by DDi Capital, the Trustee and any agent of DDi Capital or the Trustee as the absolute owner of such Global Senior Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent DDi Capital, the Trustee or any agent
of DDi Capital or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or shall impair, as between the Depositary and its Agent Members, the operation of customary practices governing
the exercise of the rights of a Holder of any Senior Note. 
  
 (b)
Transfers of a Global Senior Note shall be limited to transfers of such Global Senior Note in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Senior Note may be
transferred in accordance with the rules and procedures of the Depositary. If required to do so pursuant to any applicable law or regulation, beneficial owners may obtain Physical Senior Notes in exchange for their beneficial interests in a Global
Senior Note upon written request in accordance with the Depositary’s and the Registrar’s procedures. In addition, Physical Senior Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global
Senior Note if (i) the Depositary notifies DDi Capital that it is unwilling or unable to continue as Depositary for such Global Senior Note or the Depositary ceases to be a clearing agency registered under the Exchange Act, at a time when the
Depositary is required to be so registered in order to act as Depositary, and in each case a successor depositary is not appointed by DDi 

  

 44 








 
Capital within 90 days of such notice or, (ii) DDi Capital executes and delivers to the Trustee and Note Registrar an Officers’ Certificate stating that
such Global Senior Note shall be so exchangeable or (iii) an Event of Default has occurred and is continuing and the Note Registrar has received a request from the Depositary. 
  
 (c) In connection with any transfer of a portion of the beneficial interest in a Global Senior Note pursuant to subsection
(b) of this Section to beneficial owners who are required to hold Physical Senior Notes, the Note Registrar shall reflect on its books and records the date and a decrease in the Initial Principal Amount of such Global Senior Note in an amount equal
to the Initial Principal Amount of the beneficial interest in the Global Senior Note to be transferred, and Holdings shall execute, and the Trustee shall authenticate and deliver, one or more Physical Senior Notes of like tenor and amount.

  
 (d) In connection with the transfer of an entire Global Senior
Note to beneficial owners pursuant to subsection (b) of this Section, such Global Senior Note shall be deemed to be surrendered to the Trustee for cancellation, and Holdings shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Senior Note, an equal aggregate principal amount of Physical Senior Notes of authorized denominations. 
  
 (e) Any Physical Senior Note delivered in exchange for an interest in a
Global Senior Note pursuant to subsection (c) or subsection (d) of this Section shall, except as otherwise provided by paragraph (c) of Section 307, bear the applicable legend regarding transfer applicable to the Physical Senior Note set forth in
Section 202. 
  
 (f) The registered holder of a Global Senior Note
may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Senior Notes. 
  
 SECTION 307. Special Transfer Provisions. 
  
 (a) The Note Registrar shall retain copies of all letters, notices and other
written communications received pursuant to this Section 307. Holdings shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice
to the Note Registrar. 
  
 (b) No Obligation of the Trustee: (i)
The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Senior Note, a member of, or a participant in the Depository or other Person with respect to any ownership interest in the Senior Notes, with respect to the
accuracy of the records of the Depository or its nominee or of any participant or member thereof or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any
notice of redemption) or the payment of any amount, under or with respect to such Senior Notes. All notices and communications to be given to the Holders and all payments to be made to Holders under the Senior Notes shall be given or made only to
the registered Holders (which shall be the 

  

 45 








 
Depository or its nominee in the case of a Global Senior Note). The rights of beneficial owners in any Global Senior Note in global form shall be exercised
only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected and indemnified pursuant to Section 607 in relying upon information furnished by the Depository with
respect to any beneficial owners, its members and participants. The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law
with respect to any transfer of any interest in any Senior Note (including without limitation any transfers between or among Depository participants, members or beneficial owners in any Global Senior Note) other than to require delivery of such
certificates and other documentation of evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express
requirements hereof. 
  
 SECTION 308. Mutilated,
Destroyed, Lost and Stolen Senior Notes. 
  
 If (i) any mutilated
Senior Note is surrendered to the Trustee, or (ii) DDi Capital and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Senior Note, and there is delivered to DDi Capital and the Trustee such security or
indemnity, in each case, as may be required by them to save each of them harmless, then, in the absence of notice to DDi Capital or the Trustee that such Senior Note has been acquired by a bona fide purchaser, DDi Capital shall execute and upon
Authentication Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Senior Note or in lieu of any such destroyed, lost or stolen Senior Note, a new Senior Note of like tenor, Initial Principal Amount and Accreted
Value, bearing a number not contemporaneously outstanding. 
  
 In
case any such mutilated, destroyed, lost or stolen Senior Note has become or is about to become due and payable, DDi Capital in its discretion may, instead of issuing a new Senior Note, pay such Senior Note. 
  
 Upon the issuance of any new Senior Note under this Section, DDi Capital may
require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) in connection therewith. 
  
 Every new Senior Note issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Senior Note shall constitute an original additional contractual obligation of DDi Capital and any other obligor upon the Senior Notes, whether or not the mutilated, destroyed, lost or stolen Senior Note shall be
at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Senior Notes duly issued hereunder. 
  
 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen Senior Notes. 
  

 46 








 SECTION 309. Payment of Cash Interest; Interest Rights Preserved. 
  
 Interest on any Senior Note which is payable in cash, and is punctually paid
in cash or duly provided for, on any Interest Payment date shall be paid to the Person in whose name such Senior Note (or one or more Predecessor Senior Notes) is registered at the close of business on the Record Date for such interest at the office
or agency of DDi Capital maintained for such purpose pursuant to Section 1002; provided, however, that each installment of cash interest may at DDi Capital’s option be paid by (i) mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto pursuant to Section 310, to the address of such Person as it appears in the Note Register or (ii) wire transfer to an account located in the United States maintained by the payee. 
  
 Any cash interest on any Senior Note which is payable, but is not paid when
the same becomes due and payable and such nonpayment continues for a period of 30 days shall forthwith cease to be payable to the Holder on the Record Date by virtue of having been such Holder, and such defaulted interest and (to the extent lawful)
interest on such defaulted interest at the rate borne by the Senior Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid in cash by DDi Capital, at its election in each case, as
provided in clause (a) or (b) below: 
  
 (a) DDi Capital may
elect to make payment in cash of any Defaulted Interest to the Persons in whose names the Senior Notes (or their respective Predecessor Senior Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted
Interest, which shall be fixed in the following manner. DDi Capital shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid in cash on each Senior Note and the date (not less than 30 days after such notice) of the
proposed cash payment (the “Special Interest Payment Date”), and at the same time DDi Capital shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause
provided. Thereupon the Trustee shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the Special Interest Payment Date and
not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify DDi Capital of such Special Record Date, and in the name and at the expense of DDi Capital, shall cause notice of the
proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed
payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Senior Notes
(or their respective Predecessor Senior Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b). 
  
 (b) DDi Capital may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements
of any securities exchange on which the Senior 

  

 47 








 
Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by DDi Capital to the Trustee of the proposed payment
pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
  
 Subject to the foregoing provisions of this Section, each Senior Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Senior Note shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other Senior Note. 
  
 SECTION 310. Persons Deemed Owners. 
  
 Prior to the due presentment of a Senior Note for registration of transfer, DDi Capital, the Trustee and any agent of DDi Capital or the Trustee may treat
the Person in whose name such Senior Note is registered as the owner of such Senior Note for the purpose of receiving payment of principal of and (subject to Sections 305 and 309) interest on such Senior Note and for all other purposes whatsoever,
whether or not such Senior Note be overdue, and none of DDi Capital, the Trustee nor any agent of DDi Capital or the Trustee shall be affected by notice to the contrary. 
  
 SECTION 311. Cancellation. 
  
 All Senior Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. If DDi Capital shall acquire any of the Senior Notes other than as set forth in the preceding sentence, the acquisition shall not operate as a
redemption or satisfaction of the Indebtedness represented by such Senior Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 311. No Senior Notes shall be authenticated in lieu of or in exchange
for any Senior Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Senior Notes held by the Trustee shall be destroyed by the Trustee and the Trustee shall send a certificate of such
destruction to DDi Capital. 
  
 SECTION 312.
Computation of Interest. 
  
 Interest on the Senior Notes shall
be computed on the basis of a 360-day year of twelve 30-day months. 
  
 SECTION 313. CUSIP Numbers. 
  
 DDi Capital in issuing Senior Notes may use “CUSIP” numbers (if then generally in use) in addition to serial numbers; if so, the Trustee shall use such “CUSIP” numbers in addition to serial numbers in notices of
redemption and repurchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such CUSIP numbers, either as printed on the Senior Notes or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Senior Notes, and any such redemption or repurchase shall not be affected by any defect in or omission of such CUSIP numbers.
DDi Capital will promptly notify the Trustee of any change in the CUSIP numbers. 
  

 48 








 ARTICLE FOUR. SATISFACTION AND DISCHARGE 
  
 SECTION 401. Satisfaction and Discharge of Indenture. 
  
 This Indenture shall upon DDi Capital’s request cease to be of further
effect (except as to surviving rights of registration of transfer or exchange of Senior Notes expressly provided for herein or pursuant hereto) and the Trustee, at the expense of DDi Capital, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture when 
  
 (i) either
(A) all Senior Notes theretofore authenticated and delivered (other than (1) Senior Notes which have been lost, stolen or destroyed and which have been replaced or paid as provided in Section 308 and (2) Senior Notes for whose payment in full money
has theretofore been deposited in trust with the Trustee or any Paying Agent or segregated and held in trust by DDi Capital and thereafter repaid to DDi Capital or discharged from such trust, as provided in Section 1003) have been delivered to the
Trustee for cancellation; or (B) all Senior Notes not theretofore delivered to the Trustee for cancellation (1) have become due and payable by reason of the making of a notice of redemption or otherwise; or (2) will become due and payable at their
Stated Maturity within one year; and DDi Capital in the case of (1) or (2) above, has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose an amount in cash or Government Obligations sufficient to
pay and discharge the entire indebtedness on such Senior Notes not theretofore delivered to the Trustee for cancellation, for Accreted Value and interest to the date of such deposit (in the case of Senior Notes which have become due and payable) or
to the Stated Maturity or Redemption Date, as the case may be; 
  
 (ii) no Default or Event of Default with respect to this Indenture or the Senior Notes shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit and such deposit will not result in a breach
or violation of, or constitute a default under, any other instrument or agreement to which DDi Capital is a party or by which it is bound; 
  
 (iii) DDi Capital has paid or caused to be paid all sums payable hereunder by DDi Capital in connection with all the Senior Notes including all fees and
expenses of the Trustee; 
  
 (iv) DDi Capital has delivered
irrevocable instructions to the Trustee to apply the deposited money toward the payment of such Senior Notes at maturity or the Redemption Date, as the case may be; and 
  
 (v) DDi Capital has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture and the termination of DDi Capital’s obligation hereunder have been satisfied. 
  

 49 








 Notwithstanding the satisfaction and discharge of this Indenture, the obligations of DDi Capital under
Section 607 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (i) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive any such satisfaction
and discharge. 
  
 SECTION 402. Application of
Trust Money. 
  
 Subject to the provisions of the last paragraph
of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Senior Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including DDi Capital acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the Accreted Value and interest for whose payment such money has been deposited with the Trustee; but such money need not
be segregated from other funds except to the extent required by law. 
  
 If the Trustee or Paying Agent is unable to apply any money or Government Obligations in accordance with Section 401 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, DDi Capital’s obligations under this Indenture and the Senior Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 401; provided that if DDi Capital
has made any payment of principal of, premium, if any, or interest on any Senior Notes because of the reinstatement of its obligations, DDi Capital shall be subrogated to the rights of the Holders of such Senior Notes to receive such payment from
the money or Government Obligations held by the Trustee or Paying Agent. 
  
 ARTICLE FIVE. REMEDIES 
  
 SECTION 501.
Events of Default. 
  
 “Event of Default,” wherever
used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any
order, rule or regulation of any administrative or governmental body): 
  
 (i) a default in any payment of interest on any Senior Note at the time and in the manner due, continued for 30 days; 
  
 (ii) a default in the payment of principal of any Senior Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon
declaration or otherwise; 
  
 (iii) the failure by DDi Capital to
comply for 30 days after the notice specified below with any of its obligations under Article Eight and Sections 1006 through 1015 ( other than a failure to purchase Senior Notes when required under Sections 1012 and 1013 which shall constitute an
Event of Default under clause (ii) above); 
  

 50 








 (iv) the failure by DDi Capital to comply for 60 days after the notice specified below with any of its
other covenants or agreements contained in this Indenture or the Senior Note (other than those referred to in (i), (ii) or (iii) above); 
  
 (v) Indebtedness of DDi Capital or any Restricted Subsidiary is not paid within any applicable grace period after final maturity or is accelerated by the
Holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $3.75 million, whether such Indebtedness now exists or shall hereafter be created, which default shall constitute a failure to pay any
portion of the principal of such Indebtedness when due and payable or shall have resulted in such Indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable; 
  
 (vi) DDi Capital or any Significant Subsidiary pursuant to or within the
meaning of any applicable bankruptcy law: 
  
 (A)
commences a voluntary case; 
  
 (B) consents to
the entry of an order for relief against it in an involuntary case; 
  
 (C) consents to the appointment of a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official for all or substantially all of its property; 
  
 (D) makes a general assignment for the benefit of its
creditors; 
  
 (E) admits in writing its
inability to pay its debts generally as they become due; 
  
 (F) takes corporate action in furtherance of any of this subsection (A)-(E); 
  
 or takes any comparable action under any foreign laws relating to insolvency; or 
  
 (vii) a court of competent jurisdiction enters an order or decree under any applicable bankruptcy law, and such order or
decree remains unstayed and in effect for 90 consecutive days that: 
  
 (A) is for relief against DDi Capital or any Significant Subsidiary in an involuntary case; 
  
 (B) appoints a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of DDi Capital or any
Significant Subsidiary for all or substantially all of its property; or 
  
 (C) orders the winding up or liquidation of DDi Capital or any Significant Subsidiary; 
  
 or any similar relief is granted under any foreign laws and such order or decree remains unstayed and in effect for 90 consecutive days; or 
  

 51 








 (viii) any judgment or decree for the payment of money in excess of $3.75 million is rendered against DDi
Capital or any Significant Subsidiary and such judgment or decree remains undischarged or unstayed for a period of 60 days after such judgment becomes final and non-appealable; 
  
 A default under clauses (iii) and (iv) will not constitute an Event of Default until the Trustee or the holders of 25% in
Accreted Value of the outstanding Senior Notes notify DDi Capital of the default and DDi Capital does not cure such default within the time specified in clauses (iii) and (iv) after receipt of such notice. Such notice must specify the Default,
demand that it is to be remedied and state that such notice is a “Notice of Default.” 
  
 DDi Capital shall also deliver to the Trustee, within 10 days after the occurrence thereof, written notice of any events that with the giving of notice or
the passage of time or both would become an Event of Default under clause (iii), (iv) or (vii) above, their status and what action DDi Capital is taking or proposes to take in respect thereof. 
  
 If a Default occurs and is continuing and is known to the Trustee, the
Trustee must mail to each holder notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of Accreted Value or cash interest on any Senior Note, the Trustee may withhold notice if and so long as a
committee of its Trust officers in good faith determines that withholding notice is in the interests of the Holders of the Senior Notes. 
  
 SECTION 502. Acceleration of Maturity; Rescission and Annulment. 
  
 If an Event of Default (other than by reason of an Event of Default specified in Section 501(vi) or 501(vii)) occurs and is
continuing, the Trustee by notice to DDi Capital or the Holders of at least 25% in Accreted Value of the applicable Senior Notes outstanding may declare the Accreted Value and accrued and unpaid interest and any other monetary obligations on all
such then outstanding Senior Notes to be due and payable immediately, by a notice in writing to DDi Capital (and to the Trustee if given by Holders). Upon the effectiveness of such declaration, such Accreted Value and interest will be due and
payable immediately. Notwithstanding the foregoing, if an Event of Default specified in Section 501(vi) or 501(vii) occurs and is continuing, then the Accreted Value and accrued and unpaid interest and any other monetary obligations on all
outstanding Senior Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. 
  
 The Holders of a majority in Accreted Value of the outstanding Senior Notes by notice to the Trustee may rescind an
acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of Accreted Value or interest that has become due solely because of
acceleration. The Trustee may rely upon such notice of rescission without any independent investigation as to the satisfaction of the conditions in the preceding sentence. No such rescission shall affect any subsequent Default or impair any right
consequent thereto. 
  

 52 








 SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

  
 If an Event of Default specified in Section 501(i) or 501(ii)
occurs and is continuing, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce
the same against DDi Capital or any other obligor upon the Senior Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of DDi Capital or any other obligor upon the Senior Notes, wherever
situated. 
  
 If an Event of Default occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders under this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy, subject however to Section 513. No recovery of any such judgment upon
any property of DDi Capital shall affect or impair any rights, powers or remedies of the Trustee or the Holders. 
  
 SECTION 504. Trustee May File Proofs of Claim. 
  

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to DDi Capital or any other obligor, upon the Senior Notes or the property of DDi Capital or of such other obligor or their creditors, the Trustee (irrespective of whether the Accreted Value of the Senior Notes shall
then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on DDi Capital for the payment of overdue Accreted Value or interest) shall be entitled and empowered, by
intervention in such proceeding or otherwise, (i) to file and prove a claim for the whole amount of Accreted Value and interest owing and unpaid in respect of the Senior Notes, to take such other actions (including participating as a member, voting
or otherwise, of any official committee of creditors appointed in such matter) and to file such other papers or documents and take such other actions as the Trustee (including, participation as a member of any creditors committee) may deem necessary
or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and
(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel, and any other amounts due under Section 607. 
  
 Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Senior Notes or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of such Holders, vote for the election of a trustee in bankruptcy or other similar
official. 
  

 53 








 SECTION 505. Trustee May Enforce Claims Without Possession of Senior Notes. 

 
 All rights of action and claims under this Indenture or the Senior Notes
may be prosecuted and enforced by the Trustee without the possession of any of the Senior Notes or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as
trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Senior Notes in respect of which such judgment has been recovered. 
  
 SECTION 506. Application of Money Collected. 
  
 Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or
premium, if any) or interest, upon presentation of the Senior Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 
  
 FIRST: To the payment of all amounts due under Section 607; 
  
 SECOND: To the payment of the amounts then due and unpaid for Accreted Value and interest on the Senior Notes in respect of
which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Senior Notes for Accreted Value and interest, respectively; and 
  
 THIRD: The balance, if any, to the Person or Persons entitled thereto,
including DDi Capital or any other obligor on the Senior Notes, as their interests may appear or as a court of competent jurisdiction may direct, provided that all sums due and owing to the Holders and the Trustee have been paid in full as required
by this Indenture. 
  
 SECTION 507. Limitation on
Suits. 
  
 Except to enforce the right to receive payment of
Accreted Value or interest when due, no Holder may pursue any remedy with respect to the Indenture or the Senior Notes unless: 
  
 (i) such holder has previously given the Trustee notice that an Event of Default is continuing; 
  
 (ii) holders of at least 25% in Accreted Value of the outstanding Senior
Notes have requested the Trustee to pursue the remedy; 
  
 (iii)
such holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense; 
  

 54 








 (iv) the Trustee has not complied with such request within 60 days after the receipt of the request and
the offer of security or indemnity; and 
  
 (v) the holders of a
majority in Accreted Value of the outstanding Senior Notes have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period it being understood and intended that no one or more
Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Senior Note to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or
preference over any other Holders or to enforce any right under this Indenture or any Senior Note, except in the manner herein provided and for the equal and ratable benefit of all the Holders. 
  
 SECTION 508. Unconditional Right of Holders to Receive
Accreted Value and Interest. 
  
 Notwithstanding any other
provision in this Indenture the Holder of any Senior Note shall have the right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable, Article Eleven) and in such Senior Note of the Accreted Value of
and (subject to Section 309) interest on such Senior Note on the respective Stated Maturities expressed in such Senior Note (or, in the case of redemption or repurchase, on the Redemption Date) and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such Holder. 
  
 SECTION 509. Restoration of Rights and Remedies. 
  
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, DDi Capital, any other obligor on the
Senior Notes, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been
instituted. 
  
 SECTION 510. Rights and Remedies
Cumulative. 
  
 Except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Senior Notes in the last paragraph of Section 308, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
  

 55 








 SECTION 511. Delay or Omission Not Waiver. 
  
 No delay or omission of the Trustee or of any Holder to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the
Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be 
  
 SECTION 512. Control by Holders. 
  
 Subject to certain restrictions, the holders of a majority in Accreted Value of the outstanding Senior Notes are given the right to direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee, provided that 
  
 (i) such direction shall not be in conflict with any rule of law or the Indenture; 
  
 (ii) the Trustee need not take any action which might be unduly prejudicial
to the rights of any other Holder or would involve the Trustee in personal liability; and 
  
 (iii) subject to the provisions of Section 315 of the TIA, the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
  
 Prior to taking any action under the Indenture, the Trustee shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 
  
 SECTION 513. Waiver of Past Defaults. 
  
 Subject to Sections 508 and 902, the Holders of a majority in aggregate Accreted Value of the outstanding Senior Notes (including consents obtained in
connection with a tender offer or exchange offer for the Senior Notes) may on behalf of the Holders of all the Senior Notes, by written notice to the Trustee, waive any existing Default or Event of Default and its consequences under this Indenture
except a continuing Default or Event of Default in the payment of interest on or the Accreted Value of any such Senior Note held by a non-consenting Holder, or in respect of a covenant or a provision which cannot be amended or modified without the
consent of all Holders. 
  
 In the event that any Event of Default
specified in Section 501(v) shall have occurred and be continuing, such Event of Default and all consequences thereof (including without limitation any acceleration or resulting payment default) shall be annulled, waived and rescinded, automatically
and without any action by the Trustee or the Holders of the Senior Notes, if within 30 days after such Event of Default arose (i) the Indebtedness that is the basis for such Event of Default has been discharged, or (ii) the holders thereof have
rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default, or (iii) if the Default that is the basis for such Event of Default has been cured. 
  

 56 








 Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. 
  
 SECTION 514. Undertaking for Costs. 
  
 All parties to this Indenture agree, and each Holder of any Senior Note by
his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit
instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in Accreted Value of the outstanding Senior Notes, or to any suit instituted by any Holder for the enforcement of the payment of the Accreted Value of or interest
on any Senior Note on or after the respective Stated Maturities expressed in such Senior Note (or, in the case of redemption, on or after the Redemption Date). 
  

ARTICLE SIX. THE TRUSTEE 
  
 SECTION 601. Certain Duties and Responsibilities. 
  
 (a) Except during the continuance of a Default or an Event of Default, (i) the Trustee undertakes to perform such duties and
only such duties as are specifically set forth in this Indenture, and the Trustee should not be liable except for the performance of such duties as specifically set forth in the Indenture and no others; and no implied covenants or obligations shall
be read into this Indenture against the Trustee; and 
  
 (ii) in
the absence of bad faith or willful misconduct on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and
conforming to the requirements of this Indenture; but in the case of any such certificates or opinions, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture, but not to
verify the contents thereof. 
  
 (b) In case a Default or an Event
of Default has occurred and is continuing of which a Trust Officer of the Trustee has actual knowledge or of which written notice of such Default or Event of Default shall have been given to the Trustee of DDi Capital, any other obligor of the
Senior Notes or by any Holder, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in
the conduct of his own affairs. 
  
 (c) No provision of this
Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that 
  

 57 








 (i) this paragraph (c) shall not be construed to limit the effect of paragraph (a) of this Section;

  
 (ii) the Trustee shall not be liable for any error of judgment
made in good faith by a Trust Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and 
  
 (iii) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the
Holders of a majority in aggregate Accreted Value of the outstanding Senior Notes relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the
Trustee, under this Indenture. 
  
 (iv) the Trustee shall not be
required to examine any of the reports, information or documents filed with it pursuant to Section 1014 to determine whether there has been any breach of the covenants of DDi Capital set forth in Sections 1004 through 1021. 
  
 (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section and to the TIA. 
  
 SECTION 602. Notice of Defaults. 
  
 Within 90 days after the occurrence of any Default hereunder, the Trustee shall transmit in the manner and to the extent
provided in TIA Section 313(c), notice of such Default hereunder actually known to a Trust Officer of the Trustee, unless such Default shall have been cured or waived; provided, however, that, except in the case of a Default in the payment of the
Accreted Value of or interest on any Senior Note, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or Trust Officers of the Trustee in
good faith determine that the withholding of such notice is in the interest of the Holders. Notwithstanding anything to the contrary expressed in this Indenture, the Trustee shall not be deemed to have knowledge of any Default or Event of Default
hereunder unless and until the Trustee shall have received written notice thereof from DDi Capital at its principal Corporate Trust Office as specified in Section 105, except in the case of an Event of Default under Sections 501(i) or 501(ii)
(provided that the Trustee is the Paying Agent). 
  
 SECTION 603. Certain Rights of Trustee. 
  
 (a) If an
Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of his own affairs. 
  

 58 








 (b) Subject to the provisions of TIA Sections 315(a) through 315(d): (i) the Trustee may conclusively
rely and shall be protected in acting or refraining from acting upon (whether in its original or facsimile form) any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note,
other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties and the Trustee need not investigate any fact or matter stated in the documents; 

 
 (ii) any request or direction of DDi Capital mentioned herein shall be
sufficiently evidenced by a DDi Capital request or Authentication Order and any resolution of the Board of Directors may be sufficiently evidenced by a Board Resolution; 
  
 (iii) whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter be proved or
established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein specifically prescribed) may, in the absence of bad faith or willful misconduct on its part, request and rely upon an
Officers’ Certificate or an Opinion of Counsel and shall not liable for any action it takes or omits to take in good faith reliance on such Officer’s Certificate or Opinion of Counsel; 
  
 (iv) the Trustee may consult with counsel of its selection and any advice of
such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 
  
 (v) the Trustee shall be under no obligation to exercise any of the rights or
powers vested in it by this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity satisfactory to the Trustee against the costs,
expenses, losses and liabilities which might be incurred by it in compliance with such request or direction; 
  
 (vi) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or
matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of DDi Capital, personally or by agent or attorney; 
  
 (vii) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; and 

 
 (viii) the Trustee shall not be liable for any action taken, suffered or
omitted by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; provided, however, that the Trustee’s conduct does not constitute willful misconduct or
negligence. 
  

 59 








 (c) The Trustee shall not be required to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it. 
  
 SECTION 604.
Trustee Not Responsible for Recitals or Issuance of Senior Notes. 
  
 The recitals contained herein and in the Senior Notes, except for the Trustee’s certificates of authentication, shall be taken as the statements of DDi Capital, and the Trustee assumes no responsibility for their correctness and it
shall not be responsible for DDi Capital’s use of the proceeds from the Senior Notes. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Senior Notes, except that the Trustee represents that it is
duly authorized to execute and deliver this Indenture, authenticate the Senior Notes and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility on Form T-1 supplied to DDi Capital are true and accurate,
subject to the qualifications set forth therein. The Trustee shall not be accountable for the use or application by DDi Capital of the proceeds of the Senior Notes. 
  
 SECTION 605. May Hold Senior Notes. 
  
 The Trustee, any Paying Agent, any Note Registrar, any Authenticating Agent or any other agent of DDi Capital or of the
Trustee, in its individual or any other capacity, may become the owner or pledgee of Senior Notes and, subject to TIA Sections 310(b) and 311, may otherwise deal with DDi Capital with the same rights it would have if it were not Trustee, Paying
Agent, Note Registrar, Authenticating Agent or such other agent. 
  
 SECTION 606. Money Held in Trust. 
  
 All moneys received by the Trustee shall, until used or applied as herein provided, be held in trust hereunder for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law.
The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with DDi Capital. 
  
 SECTION 607. Compensation and Reimbursement. 
  
 DDi Capital agrees 
  
 (i) to pay to the Trustee from time to time such compensation as shall be agreed to in writing between DDi Capital and the Trustee for all services
rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 
  

 60 








 (ii) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents, consultants and counsel and
costs and expenses of collection on the Senior Notes and enforcement and administration of any right or remedy or observing any of its duty under this Indenture), except any such expense, disbursement or advance as may be attributable to its
negligence or bad faith; and 
  
 (iii) to indemnify each of the
Trustee or any predecessor Trustee (and each of their respective directors, officers, stockholders, employees and agents) for, and to hold them harmless against, (a) any and all loss, damage, claim, liability or expense, including taxes (other than
taxes based on the income of the Trustee) incurred without negligence, willful misconduct or bad faith on their part, arising out of or in connection with the acceptance or administration of this trust, and (b) the costs and expenses of defending
themselves against any claim or liability in connection with the exercise or performance of any of the Trustee’s powers or duties hereunder. 
  
 The obligations of DDi Capital under this Section to compensate the Trustee, to pay or reimburse the Trustee for expenses, disbursements and advances and
to indemnify and hold harmless the Trustee shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this Indenture. As security for the performance of such obligations of DDi Capital, the Trustee shall
have a lien, for its benefit, prior to the Holders of the Senior Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of Accreted Value or interest on particular Senior Notes.

  
 When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 501(vi) or (vii), the expenses (including the reasonable charges and expenses of its counsel) of and the compensation for such services are intended to constitute expenses of administration
under any applicable federal or state bankruptcy, insolvency or other similar law. 
  
 The provisions of this Section shall survive the termination of this Indenture. 
  
 SECTION 608. Corporate Trustee Required; Eligibility. 
  
 There shall be at all times a Trustee hereunder which shall be eligible to act as Trustee under TIA Section 310(a)(1), and
which may have an office in The City of New York and shall have a combined capital and surplus of at least $50,000,000. If the Trustee does not have an office in The City of New York, the Trustee may appoint an agent in The City of New York
reasonably acceptable to DDi Capital to conduct any activities which the Trustee may be required under this Indenture to conduct in The City of New York. If such corporation publishes reports of condition at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section 608, the combined capital and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 608, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article. 
  

 61 








 SECTION 609. Resignation and Removal; Appointment of Successor. 
  
 (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of this Section. 
  
 (b) The Trustee may resign at any time by giving written notice thereof to
DDi Capital. Upon receiving such notice of resignation, DDi Capital shall promptly appoint a successor trustee by written instrument executed by authority of the Board of Directors, a copy of which shall be delivered to the resigning Trustee and a
copy to the successor trustee. If an instrument of acceptance required by this Section shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of
DDi Capital, any court of competent jurisdiction for the appointment of a successor Trustee. 
  
 (c) The Trustee may be removed at any time by Act of the Holders of not less than a majority in principal amount of the outstanding Senior Notes, delivered to the Trustee and to DDi Capital. The Trustee so removed
may, at the expense of DDi Capital, petition any court of competent jurisdiction for the appointment of a successor Trustee if no successor Trustee is appointed within 30 days of such removal. 
  
 (d) If at any time: 
  
 (i) the Trustee shall fail to comply with the provisions of TIA Section
310(b) after written request therefor by DDi Capital or by any Holder who has been a bona fide Holder of a Senior Note for at least six months, or 
  
 (ii) the Trustee shall cease to be eligible under Section 608 and shall fail to resign after written request therefor by DDi Capital or by any Holder who
has been a bona fide Holder of a Senior Note for at least six months, or 
  
 (iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a custodian of the Trustee or of its property shall be appointed or any public officer shall take charge or control of
the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (A) DDi Capital, by a Board Resolution, may remove the Trustee, or (B) subject to TIA Section 315(e), any Holder who
has been a bona fide Holder of a Senior Note for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

  
 (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, DDi Capital, by a Board Resolution, shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of 

  

 62 








 
the Holders of a majority in principal amount of the outstanding Senior Notes delivered to DDi Capital and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by DDi Capital. If no successor Trustee shall have been so appointed by DDi Capital or the Holders and
accepted appointment in the manner hereinafter provided, any Holder who has been a bona fide Holder of a Senior Note for at least six months may, at the expense of DDi Capital on behalf of himself and all others similarly situated, petition any
court of competent jurisdiction for the appointment of a successor Trustee. 
  
 (f) DDi Capital shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to the Holders of Senior Notes in the manner provided for in Section 106. Each notice
shall include the name of the successor Trustee and the address of its Corporate Trust Office. 
  
 SECTION 610. Acceptance of Appointment by Successor. 
  
 Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to DDi Capital and to the retiring
Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on request of DDi Capital or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee
all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Notwithstanding the replacement of the Trustee pursuant
to this Section 610, DDi Capital’s obligations under Section 607 shall continue for the benefit of the retiring Trustee with regard to expenses and liabilities incurred by it and compensation earned by it prior to such replacement or otherwise
under the Indenture. Upon request of any such successor Trustee, DDi Capital shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. 
  
 No successor Trustee shall accept its appointment unless at the time of such
acceptance such successor Trustee shall be qualified and eligible under this Article. 
  
 SECTION 611. Merger, Conversion, Consolidation or Succession to Business. 
  
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Senior Notes shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Senior Notes so authenticated with the same effect as if such 

  

 63 








 
successor Trustee had itself authenticated such Senior Notes. In case at that time any of the Senior Notes shall not have been authenticated, any successor
Trustee may authenticate such Senior Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the
certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Senior Notes in the name of any predecessor Trustee shall apply only
to its successor or successors by merger, conversion or consolidation. 
  
 SECTION 612. Trustee’s Application for Instructions from DDi Capital. 
  
 Any application by the Trustee for written instructions from DDi Capital may, at the option of the Trustee, set forth in writing any action proposed to be
taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. Subject to Section 610, the Trustee shall not be liable for any action taken by, or omission of,
the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer of DDi Capital actually receives such
application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to
such application specifying the action to be taken or omitted. 
  
 ARTICLE SEVEN. HOLDERS LISTS AND REPORTS BY TRUSTEE AND HOLDINGS 
  
 SECTION 701. DDi Capital to Furnish Trustee Names and Addresses. 
  
 DDi Capital will furnish or cause to be furnished to the Trustee (a) quarterly, not more than 10 days after each Record Date, a list, in such form as the
Trustee may reasonably require, of the names and addresses of the Holders as of such Record Date; and (b) at such other times as the Trustee may reasonably request in writing, within 30 days after receipt by DDi Capital of any such request, a list
of similar form and content to that in Subsection (a) hereof as of a date not more than 15 days prior to the time such list is furnished; provided, however, that if and so long as the Trustee shall be the Note Registrar, no such list need be
furnished. 
  
 SECTION 702. Disclosure of Names
and Addresses of Holders. 
  
 Every Holder of Senior Notes, by
receiving and holding the same, agrees with DDi Capital and the Trustee that none of DDi Capital or the Trustee or any agent of either of them shall be held accountable by reason of the disclosure of any such information as to the names and
addresses of the Holders in accordance with TIA Section 312, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under TIA
Section 312(b) 
  

 64 








 SECTION 703. Reports by Trustee. 
  
 Within 60 days after May 15 of each year commencing with the first May 15
after the first issuance of Senior Notes, the Trustee shall transmit to the Holders, in the manner and to the extent provided in TIA Section 313(c), a brief report dated as of such May 15 if required by TIA Section 313(a). Delivery of such reports,
information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein,
including DDi Capital’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely exclusively on Officer’s Certificates). 
  
 The Trustee also shall comply with TIA Section 313(b). A copy of each report at the time of its mailing to Holders shall be
filed by the Trustee with the SEC and each stock exchange (if any) on which the Senior Notes are listed. DDi Capital agrees to notify promptly the Trustee whenever the Senior Notes become listed on any stock exchange and of any delisting thereof.

  
 ARTICLE EIGHT. MERGER, CONSOLIDATION, OR SALE OF ASSETS

  
 SECTION 801. DDi Capital May Consolidate,
Etc., Only on Certain Terms. 
  
 DDi Capital will not in a single
transaction or series of related transactions consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets to any Person, unless: 
  
 (i) the resulting, surviving or transferee Person (the “Successor Company”) shall be a corporation, partnership,
trust or limited liability company organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Company (if not DDi Capital) shall expressly assume, by supplemental indenture,
executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of DDi Capital under the Senior Notes and hereunder; 
  
 (ii) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Company or any
Subsidiary of the Successor Company as a result of such transaction as having been incurred by the Successor Company or such Restricted Subsidiary at the time of such transaction), no Default or Event of Default shall have occurred and be
continuing; 
  
 (iii) immediately after giving effect to such
transaction, DDi Capital or the Successor Company if DDi Capital is not the continuing obligor under this Indenture would at the time of such transaction or series of transactions, after giving pro forma effect to such transaction have a
Consolidated Net Worth not less than that of DDi Capital immediately prior to the transaction; and 
  
 (iv) DDi Capital shall have delivered to the Trustee (A) an Officers’ Certificate, stating that (1) such Officers are not aware of any Default or
Event of Default that shall have happened and be continuing and (2) such consolidation, merger or transfer and such supplemental indenture comply with this Indenture; provided that no Officers’ Certificate will be required as to matters
described in clause (A)(1) of this clause (iv) for a consolidation, merger or transfer

 ARTICLE NINE. SUPPLEMENTS AND AMENDMENTS TO INDENTURE 
  
 SECTION 901. Supplemental Indentures Without Consent of
Holders. 
  
 Without the consent of any Holders, DDi Capital and
the Trustee, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Trustee, for any of the following purposes: 
  
 (i) to cure any ambiguity, omission, defect or inconsistency; 
  
 or 
  
 (ii) to provide for uncertificated Senior Notes in addition to or in place of certificated Senior Notes (provided that the uncertificated Senior Notes are
issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Senior Notes are described in Section 163(f)(2)(B) of the Code); or 
  

 66 








 (iii) to add Guarantees with respect to the Senior Notes; or 
  
 (iv) to provide for the assumption by a successor corporation, partnership,
trust or limited liability company of the obligations of DDi Capital hereunder; or 
  
 (v) to secure the Senior Notes; or

 (viii) to comply with any requirement of the SEC in connection with the qualification of this Indenture under the TIA.

  
 SECTION 902. Supplemental Indentures with
Consent of Holders. 
  
 With the consent of the Holders of at
least a majority in Accreted Value of the outstanding Senior Notes (including consents obtained in connection with a tender offer or exchange offer for the Senior Notes), DDi Capital, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders under this Indenture; provided, however, that
the provisions of Section 1006(b)(vi)(C) may be amended with the consent of Holders of at least 33  1/3% in
Accreted Value of the outstanding Senior Notes or two Holders in number (regardless of the Accreted Value of the outstanding Senior Notes held by such Holders), and provided, further, that no such supplemental indenture shall, without the consent of
the Holder of each outstanding Senior Note affected thereby (with respect to any Senior Notes held by a nonconsenting Holder of the Senior Notes): 
  
 (i) reduce the Accreted Value of Senior Notes whose Holders must consent to an amendment; or 
  
 (ii) reduce the stated rate of or extend the stated time for payment of interest on any Senior Note; or 
  
 (iii) reduce the Initial Principal Amount or Accreted Value of or extend the

 (vii) make any change in the amendment provisions which require each Holder’s consent or in the
waiver provisions. 
  
 The consent of the Holders is not necessary
under this Indenture to approve the particular form of any proposed amendment or supplemental indenture. It is sufficient if such consent approves the substance of the proposed amendment or supplemental indenture. 
  
 SECTION 903. Execution of Supplemental Indentures.

  
 The Trustee may, but shall not be obligated to, enter into
any such supplemental indenture which affects the Trustee’s own rights, duties or immunities, as determined by the Trustee in its sole discretion under this Indenture or otherwise. In signing or refusing to sign any supplemental indenture
permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Officer’s Certificate and an Opinion of Counsel stating
that the execution of such supplemental indenture is authorized or permitted by this Indenture. 
  
 SECTION 904. Effect of Supplemental Indentures. 
  

Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder of Senior Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby (except as provided in Section 902). 
  
 SECTION 905. Conformity with Trust Indenture Act.

  
 Every supplemental indenture executed pursuant to the Article
shall conform to the requirements of the TIA as then in effect. 
  
 SECTION 906. Reference in Senior Notes to Supplemental Indentures. 
  
 Senior Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the
Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If DDi Capital or the Trustee shall so determine, new Senior Notes so modified as to conform to any such supplemental indenture
may be prepared and executed by DDi Capital, and DDi Capital shall issue and the Trustee shall authenticate a new Senior Note that reflects the changed terms, the cost and expense of which will be borne by DDi Capital in exchange for outstanding
Senior Notes. 
  
 SECTION 907. Notice of
Supplemental Indentures. 
  
 Promptly after the execution by DDi
Capital and the Trustee of any supplemental 

  

 68 








 
indenture pursuant to the provisions of Section 902, DDi Capital shall give notice thereof to the Holders of each outstanding Senior Note affected, in the
manner provided for in Section 106, setting forth in general terms the substance of such supplemental indenture. The failure to give such notice to all the Holders, or any defect therein, will not impair or affect the validity of the supplemental
indenture. 
  
 ARTICLE TEN. COVENANTS 
  
 SECTION 1001. Payment of Accreted Value and Interest.

  
 DDi Capital covenants and agrees for the benefit of the
Holders that it will duly and punctually pay the Accreted Value of and interest on the Senior Notes in accordance with the terms of the Senior Notes and this Indenture. 
  
 SECTION 1002. Maintenance of Office or Agency. 
  
 DDi Capital will maintain in The City of New York an office or agency where
the Senior Notes may be presented or surrendered for payment (“Paying Agent”), where, if applicable, the Senior Notes may be surrendered for registration of transfer or exchange and where notices and demands to or upon DDi Capital in
respect of the Senior Notes and this Indenture may be served. The corporate trust office of the Trustee shall be the Corporate Trust Office, unless DDi Capital shall designate and maintain some other office or agency for one or more of such
purposes. DDi Capital will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time DDi Capital shall fail to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and DDi Capital hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands. 
  
 DDi Capital may also from
time to time designate one or more other offices or agencies (in or outside of The City of New York) where the Senior Notes may be presented or surrendered for any or all such purposes and may from time to time rescind any such designation;
provided, however, that no such designation or rescission shall in any manner relieve DDi Capital of its obligation to maintain an office or agency in The City of New York for such purposes. DDi Capital will give prompt written notice to the Trustee
of any such designation or rescission and any change in the location of any such other office or agency. 
  
 SECTION 1003. Money for Note Payments to Be Held in Trust. 
  
 If DDi Capital shall at any time act as its own Paying Agent, it will, on or before each due date of the Accreted Value of
or interest on any of the Senior Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the Accreted Value of or interest so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its action or failure to so act. 
  
 Whenever DDi Capital shall have one or more Paying Agents for the Senior Notes, it 

  

 69 








 
will, on or before each due date of the Accreted Value of or interest on any Senior Notes, deposit with a Paying Agent a sum in same day funds (or New York
Clearing House funds if such deposit is made prior to the date on which such deposit is required to be made) that shall be available to the Trustee by 10:00 a.m. Eastern Standard Time on such due date sufficient to pay the Accreted Value of and/or
interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such Accreted Value and/or interest, and (unless such Paying Agent is the Trustee) DDi Capital will promptly notify the Trustee of such action or any
failure to so act. 
  
 DDi Capital will cause each Paying Agent
(other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 
  
 (i) hold all sums held by it for the payment of Accreted Value of or
interest on Senior Notes in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 
  
 (ii) give the Trustee notice of any default by DDi Capital (or any other obligor upon the Senior Notes) in the making of any
Accreted Value or interest; and 
  
 (iii) at any time during the
continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
  
 DDi Capital may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by
Authentication Order direct any Paying Agent to pay, to the Trustee all sums held in trust by DDi Capital or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by DDi Capital or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums. 
  
 Any money deposited with the Trustee or any Paying Agent, or then held by DDi Capital, in trust for the payment of the
Accreted Value of or interest on any Senior Note and remaining unclaimed for two years after such Accreted Value or interest has become due and payable shall be paid to DDi Capital on DDi Capital Request, or (if then held by DDi Capital) shall be
discharged from such trust; and the Holder of such Senior Note shall thereafter, as an unsecured general creditor, look only to DDi Capital for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of DDi Capital as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment to DDi Capital, may at the expense of DDi Capital cause to be
published once, in a leading daily newspaper (if practicable, The Wall Street Journal (Eastern Edition)) printed in the English language and of general circulation in New York City, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to DDi Capital. 
  

 70 








 SECTION 1004. Corporate Existence. 
  
 Subject to Article Eight, DDi Capital will do or cause to be done all things necessary to preserve and keep in full force
and effect its corporate existence and that of each Restricted Subsidiary and the corporate rights (charter and statutory) licenses and franchises of DDi Capital and each Restricted Subsidiary; provided, however, that DDi Capital shall not be
required to preserve any such existence (except for DDi Capital), right, license or franchise if the Board of Directors of DDi Capital shall determine that the preservation thereof is no longer desirable in the conduct of the business of DDi Capital
and each of its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not, and will not be, disadvantageous in any material respect to the Holders. 
  
 SECTION 1005. Payment of Taxes and Other Claims. 
  
 DDi Capital will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all
material taxes, assessments and governmental charges levied or imposed upon DDi Capital or any Subsidiary or upon the income, profits or property of DDi Capital or any Subsidiary and (ii) all lawful claims for labor, materials and supplies, which,
if unpaid, might by law become a material liability or lien upon the property of DDi Capital or any Restricted Subsidiary; provided, however, that DDi Capital shall not be required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings and for which appropriate reserves, if necessary (in the good faith judgment of management of DDi Capital) are being
maintained in accordance with GAAP. 
  
 DDi Capital shall comply,
and shall cause each of its Restricted Subsidiaries to comply, with all applicable statutes, rules, regulations, orders and restrictions of the United States of America, all states and municipalities thereof, and of any governmental regulatory
authority, in respect of the conduct of their respective businesses and the ownership of their respective properties, except for such noncompliances as would not in the aggregate have a material adverse effect on the financial condition or results
of operations of DDi Capital and its Restricted Subsidiaries, taken as a whole. 
  
 SECTION 1006. Limitation on Restricted Payments. 
  
 (a) DDi Capital shall not, and shall not permit any of its Restricted Subsidiaries, directly or indirectly, to (i) declare or pay any dividend or make any distribution on or in respect of its Capital Stock except (A)
dividends or distributions payable in its Capital Stock (other than Disqualified Stock), and (B) dividends or distributions payable to DDi Capital or a Restricted Subsidiary of DDi Capital (and if such Restricted Subsidiary is not a Wholly-Owned
Subsidiary, to its other holders of Capital Stock on a pro rata basis), (ii) purchase, redeem, retire or otherwise acquire for value any Capital Stock of DDi Capital held by Persons other than a Restricted Subsidiary of DDi Capital or any Capital
Stock of a Restricted Subsidiary of DDi Capital held by any Affiliate of DDi Capital, other than another Restricted Subsidiary (in either case, other than in exchange for its Capital Stock (other than Disqualified Stock)), (iii) purchase,
repurchase, redeem, defease or otherwise acquire or retire for value, prior to scheduled maturity, scheduled repayment or scheduled sinking fund payment, any Subordinated Obligations (other than the 

  

 71 








 
purchase, repurchase or other acquisition of Subordinated Obligations purchased in anticipation of satisfying a sinking fund obligation, principal
installment or final maturity, in each case due within one year of the date of purchase, repurchase or acquisition) or (iv) make any Investment (other than a Permitted Investment) in any Person (any such dividend, distribution, purchase, redemption,
repurchase, defeasance, other acquisition, retirement or Investment being herein referred to in clauses (i) through (iv) as a “Restricted Payment”), if at the time DDi Capital or such Restricted Subsidiary makes such Restricted Payment:
(1) a Default or an Event of Default shall have occurred and be continuing (or would result therefrom); or (2) the Company is not able to incur an additional $1.00 of Indebtedness pursuant to Section 1008; or (3) the aggregate amount of such
Restricted Payment and all other Restricted Payments declared or made subsequent to the Issue Date would exceed the sum of: (A) 50% of the Consolidated Net Income (x) of DDi Capital in the case of any Restricted Payment made by DDi Capital or (y) of
the Company and its Restricted Subsidiaries in the case of any Restricted Payment made by the Company or any of its Restricted Subsidiaries accrued during the period (treated as one accounting period) from, but excluding, the Issue Date to, but
excluding, the date of such Restricted Payment (or, in case such Consolidated Net Income shall be a deficit, minus 100% of such deficit); (B) the aggregate net proceeds, including the fair market value of property other than cash (determined in good
faith by the Board of Directors as evidenced by a certificate filed with the Trustee, except that in the event the value of any non-cash consideration shall be $10 million or more, the value shall be as determined in writing by an Independent
Appraiser) received by DDi Capital from the issue or sale of its Capital Stock (other than Disqualified Stock) or other capital contributions subsequent to the Issue Date (other than net proceeds received from an issuance or sale of such Capital
Stock to a Subsidiary of DDi Capital or an employee stock ownership plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans from DDi Capital or any Restricted Subsidiary unless such
loans have been repaid with cash on or prior to the date of determination); (C) the amount by which Indebtedness of DDi Capital is reduced on DDi Capital’s balance sheet upon the conversion or exchange (other than by a Subsidiary of DDi
Capital) subsequent to the Issue Date of any Indebtedness of DDi Capital convertible or exchangeable for Capital Stock of DDi Capital (less the amount of any cash, or other property, distributed by DDi Capital upon such conversion or exchange); (D)
the amount equal to the net reduction in Investments made by DDi Capital or any of its Restricted Subsidiaries in any Person resulting from (i) repurchases or redemptions of such Investments by such Person, proceeds realized upon the sale of such
Investment to an unaffiliated purchaser, repayments of loans or advances or other transfers of assets (including by way of dividend or distribution) by such Person to DDi Capital or any Restricted Subsidiary of DDi Capital or (ii) the redesignation
of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the definition of “Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by DDi Capital
or any Restricted Subsidiary in such Unrestricted Subsidiary, which amount was included in the calculation of the amount of Restricted Payments; provided, however, that no amount shall be included under this clause (D) to the extent it is already
included in Consolidated Net Income. 
  
 (b) The provisions of the
foregoing paragraph (a) shall not prohibit: (i) any purchase or redemption of Capital Stock or Subordinated Obligations of DDi Capital or any Restricted Subsidiary made by exchange for, or out of the proceeds of the substantially concurrent sale of,


  

 72 








 
Capital Stock of DDi Capital (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary or pursuant to an employee stock
ownership plan or similar trust to the extent such sale pursuant to such plan is financed by loans from DDi Capital or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination); provided,
however, that (A) such purchase or redemption shall be excluded in subsequent calculations of the amount of Restricted Payments and (B) the aggregate net proceeds from such sale shall be excluded from clause (3) (B) of paragraph (a); (ii) any
purchase or redemption of Subordinated Obligations of DDi Capital made by exchange for, or out of the proceeds of the substantially concurrent sale of, Subordinated Obligations of DDi Capital; provided, however, that such purchase or redemption
shall be excluded in subsequent calculations of the amount of Restricted Payments; (iii) dividends paid within 60 days after the date of declaration if at such date of declaration such dividend would have complied with this provision; provided,
however, that such dividend shall be included in subsequent calculations of the amount of Restricted Payments; (iv) payments for the purpose of, and in amounts equal to, amounts required to permit DDi Capital to redeem or repurchase Capital Stock of
DDi Capital or the Parent from existing or former employees or management of DDi Capital or any Parent thereof or any Subsidiary or their assigns, estates or heirs, in each case in connection with an employee stock ownership plan or similar trust;
provided that such redemption or repurchases pursuant to this clause shall not exceed $1.0 million (and such maximum amount shall be increased by the amount of any proceeds to the Company, Parent or DDi Capital from (x) sales of Capital Stock of DDi
Capital to management employees subsequent to the Issue Date and (y) any “key- man” life insurance policies which are used to make such redemptions or repurchases) in the aggregate; provided, however, that such payments shall be included
in the calculation of the amount of Restricted Payments; provided, further, that the cancellation of Indebtedness owing to DDi Capital, any Parent thereof or the Company from members of management in connection with a repurchase of Capital Stock of
DDi Capital, Parent or the Company will not be deemed to constitute a Restricted Payment under the Indenture; (v) loans or advances made after the Issue Date to employees or directors of DDi Capital, Parent or any Subsidiary the proceeds of which
are used to purchase Capital Stock of DDi Capital or any Parent thereof, in an aggregate amount not in excess of $1.0 million at any one time outstanding; provided, however, that such payments shall be included in the calculation of the amount of
Restricted Payments; (vi) cash dividends to the Parent, if any, in an amount not to exceed in any fiscal year of DDI Capital the sum of (A) the amounts required for DDi Capital or the Parent to pay any Federal, state or local income taxes to the
extent that such income taxes are attributable to the income of DDi Capital and its Subsidiaries, plus (B) the amounts required for DDi Capital or the Parent to pay franchise taxes and other fees required to maintain its legal existence, plus (C) an
amount not to exceed $1,000,000 in any fiscal year to permit DDi Capital or the Parent to pay its corporate overhead expenses incurred and lawfully paid in maintaining its status as a public entity provided that the aggregate amount distributed
pursuant to this Section 1006(b)(vi)(C) shall not exceed the aggregate amount of dividends distributed by the Company for such amounts pursuant to the Senior Credit Agreement, plus (D) so long as no Default or Event of Default shall have occurred
and be continuing, an amount not to exceed $100,000 in the aggregate, to enable DDi Capital or the Parent to make payments to holders of its Capital Stock in lieu of issuance of fractional shares of its Capital Stock, plus (E) an aggregate amount
not to exceed $500,000 plus accrued interest thereon to enable Parent to repay in full the Houlihan Lokey Note; provided, however, that such payments shall not be included in the calculation of the amount of Restricted Payments; 
  

 73 








 
and (vii) repurchases of Capital Stock deemed to occur upon the exercise of stock options if such Capital Stock represents a portion of the exercise price
hereof; provided, however, that such repurchases shall not be included in the calculation of the amount of Restricted Payments. 
  
 (c) Not later than the date of making any Restricted Payment, DDi Capital shall deliver to the Trustee an Officers’ Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 1006 were computed, which calculations may be based upon DDi Capital’s latest available financial statements. The Trustee shall
have no duty to recompute or recalculate or verify the accuracy of the information set forth in such Officers’ Certificate. 
  
 (d) DDi Capital will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except in compliance with the second to last sentence of the
definition of “Unrestricted Subsidiary.” 
  
 SECTION 1007. Limitation on Indebtedness by DDi Capital. 
  
 (a) DDi Capital shall not Incur any Indebtedness, other than (i) the Indebtedness represented by or Incurred pursuant to (A) the Senior Notes, (B) the Senior Credit Agrement, (C) the Houlihan Lokey Note, and (D) Indebtedness of DDi Capital
owing to and held by any Wholly-Owned Subsidiary if such Indebtedness is subordinated in right of payment to the Senior Notes and the proceeds thereof are not used to pay dividends to DDi Capital’s stockholders; provided, however, that any
subsequent issuance or transfer of any Capital Stock or any other event which results in any such Wholly-Owned Subsidiary ceasing to be a Wholly-Owned Subsidiary or any subsequent transfer of any such Indebtedness (except to DDi Capital or a Wholly-
Owned Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Indebtedness by DDi Capital and (ii) Indebtedness (other than Indebtedness described in clauses (i)(A)–(D) above) in a principal amount which, when taken
together with the aggregate principal amount of all other Indebtedness Incurred pursuant to Section 1008(b)(xiii) and this clause (ii) and then outstanding, will not exceed $10 million, provided that such Indebtedness (A) is subordinated to
the prior payment in full in cash of all obligations under the Senior Notes and this Indenture and (B) does not provide for the cash payment of principal or interest prior to the maturity date of the Senior Notes. 
  
 (b) DDi Capital will not, and will not permit any Subsidiary to, issue,
assume, Guarantee or otherwise become liable for any Indebtedness that is both (a) subordinate or junior in right of payment to any Senior Secured Indebtedness or the Houlihan Lokey Note and (b) senior in any respect in right of payment to the
Senior Notes. 
  
 SECTION 1008. Limitation on
Indebtedness by the Company. 
  
 (a) The Company shall not, and
shall not permit any of its Restricted Subsidiaries to, Incur any Indebtedness; provided, however, that the Company and its Restricted Subsidiaries may Incur Indebtedness if on the date thereof the Consolidated Coverage Ratio for the Company and its
Restricted Subsidiaries is at least (i) 2.00 to 1.00, if such Indebtedness is Incurred on or prior to the second anniversary of the Issue Date and (ii) 2.25 to 1.00, if such Indebtedness is Incurred thereafter. 
  

 74 








 (b) Notwithstanding the foregoing paragraph (a), the Company and its Restricted Subsidiaries may Incur
the following Indebtedness: 
  
 (i) Indebtedness
Incurred pursuant to the Senior Credit Agreement; provided, however, that the aggregate principal amount of all Indebtedness Incurred pursuant to this clause (i) does not at any date exceed the greater of $100 million or three times Consolidated
EBITDA of the Company for the period of the most recent four consecutive fiscal quarters ending prior to such date, less the aggregate principal amount of all mandatory prepayments of principal thereof with the proceeds of Asset Dispositions;

  
 (ii) Indebtedness of the Company owing to and
held by any Wholly-Owned Subsidiary or Indebtedness of a Restricted Subsidiary owing to and held by the Company or any Wholly-Owned Subsidiary; provided, however, that any subsequent issuance or transfer of any Capital Stock or any other event which
results in any such Wholly-Owned Subsidiary ceasing to be a Wholly-Owned Subsidiary or any subsequent transfer of any such Indebtedness (except to the Company or a Wholly-Owned Subsidiary) shall be deemed, in each case, to constitute the Incurrence
of such Indebtedness by the issuer thereof; 
  
 (iii) Indebtedness represented by (x) any Indebtedness (other than the Indebtedness described in clauses (i) and (ii)) outstanding on the Issue Date and (y) any Refinancing Indebtedness Incurred in respect of any Indebtedness described in
this clause (iii) or clause (iv) or Incurred pursuant to paragraph (a) of this Section; 
  
 (iv) Indebtedness of a Restricted Subsidiary Incurred and outstanding on the date on which such Restricted Subsidiary became a Restricted
Subsidiary or was acquired by the Company (other than Indebtedness Incurred to provide all or any portion of the funds utilized to consummate the transaction or series of related transactions pursuant to which such Restricted Subsidiary became a
Subsidiary or was otherwise acquired by the Company); provided, however, that at the time such Restricted Subsidiary is acquired by the Company, the Company would have been able to Incur $1.00 of additional Indebtedness under this Section 1008 after
giving effect to the Incurrence of such Indebtedness pursuant to this clause (iv); 
  
 (v) Indebtedness under Currency Agreements and Interest Rate Agreements; provided, however, that in the case of Currency Agreements and
Interest Rate Agreements, such Currency Agreements and Interest Rate Agreements are entered into for bona fide hedging purposes of the Company or its Restricted Subsidiaries (as determined in good faith by the Board of Directors or senior management
of the Company) and correspond in terms of notional amount, duration, currencies and interest rates, as applicable, to Indebtedness of the Company or its Restricted Subsidiaries Incurred without violation of the Indenture or to business transactions
of the Company or its Restricted Subsidiaries on customary terms entered into in the ordinary course of business; 
  

 75 








 (vi) Indebtedness of foreign Restricted Subsidiaries under working capital facilities;
provided that the aggregate principal amount of such Indebtedness outstanding at any time does not exceed 5% of Consolidated Tangible Assets; 
  
 (vii) Indebtedness (including Capital Lease Obligations) incurred by the Company or any of its Restricted Subsidiaries to finance the
purchase, lease or improvement of property (real or personal) or equipment (whether through the direct purchase of assets or the Capital Stock of any Person owning such assets) in an aggregate principal amount outstanding not to exceed the greater
of (A) $5.0 million or (B) 5% of Consolidated Tangible Assets at the time of any Incurrence thereof (including any Refinancing Indebtedness with respect thereto);

reimbursement type obligations regarding workers’ compensation claims; 
  
 (ix) Indebtedness arising from agreements of the Company or a Restricted Subsidiary of the Company providing for indemnification, adjustment of purchase price, earn out or other similar obligations, in each case,
incurred or assumed in connection with the disposition of any business, assets or a Restricted Subsidiary of the Company, provided that the maximum liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually
received by the Company and its Restricted Subsidiaries in connection with such disposition;

Available Cash in accordance herewith except to the extent that the aggregate Net Available Cash from all Asset Dispositions which are not applied in accordance with this covenant exceed $5 million. DDi Capital shall not be required to make an Offer
for the Senior Notes pursuant to this covenant if the Net Available Cash available therefor (after application of the proceeds as provided in clauses (A), (B) and (C)) are less than $5 million for any particular Asset Disposition (which lesser
amounts shall be carried forward for purposes of determining whether an Offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). 
  
 (b) For the purposes of this covenant, the following will be deemed to be cash: (x) the assumption by the transferee of
Indebtedness of any Restricted Subsidiary of DDi Capital and the release of DDi Capital or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition (in which case DDi Capital shall, without further
action, be deemed to have applied such assumed Indebtedness in accordance with clause (A) of the preceding paragraph), (y) securities received by DDi Capital or any Restricted Subsidiary of DDi Capital from the transferee that are promptly converted
by DDi Capital or such Restricted Subsidiary into cash and (z) any Designated Noncash Consideration received by DDi Capital or any of its Restricted Subsidiaries in such Asset Disposition having an aggregate fair market value, taken together with
all other Designated Noncash Consideration received pursuant to this clause (z) that is at that time outstanding, not to exceed 10% of Consolidated Tangible Assets at the time of the receipt of such Designated Noncash Consideration (with the fair
market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value). 
  
 (c) In the event of an Asset Disposition that requires the purchase of Senior Notes pursuant to clause (a)(iii)(C), DDi Capital will be required to
purchase Senior Notes tendered pursuant to an offer by DDi Capital for the Senior Notes at a price in cash equal to 100% of the Accreted Value thereof plus accrued and unpaid interest, if any, to the purchase date in accordance with the procedures
(including prorating in the event of oversubscription) set forth in this Indenture. If the aggregate purchase price of the Senior Notes tendered pursuant to the offer is less than the Net Available Cash allotted to the purchase of the Senior Notes,
DDi Capital will apply the remaining Net Available Cash in accordance with clause (a)(iii)(D) above. 
  
 (d) DDi Capital will comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or
regulations in connection with the repurchase of Senior Notes pursuant to the Indenture. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, DDi Capital will comply with the applicable
securities laws and regulations and will not be deemed to have breached its obligations under the Indenture by virtue thereof.

Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 1205 and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all its other obligations under
such Senior Notes and this Indenture insofar as such Senior Notes are concerned (and the Trustee, at the expense of DDi Capital, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise
terminated or discharged hereunder: (i) the rights of Holders of outstanding Senior Notes to receive, solely from the trust fund described in Section 1204 and as more fully set forth in such Section, payments in respect of the Accreted Value of and
interest on such Senior Notes when such payments are due, (ii) DDi Capital’s obligations with respect to such Senior Notes under Sections 304, 305, 308, 1002 and 1003, (iii) the rights, powers, trusts, duties and immunities of the Trustee
hereunder, and DDi Capital’s obligations in connection therewith and (iv) this Article Twelve. 
  
 If DDi Capital exercises its Legal Defeasance Option, payment of the Senior Notes may not be accelerated because of an Event of Default. 
  
 Subject to compliance with this Article Twelve, DDi Capital may exercise its
option under this Section 1202 notwithstanding the prior exercise of its option under Section 1203 with respect to the Senior Notes. 
  
 SECTION 1203. Covenant Defeasance. 
  
 Upon DDi Capital’s exercise under Section 1201 of the option applicable to this Section 1203, DDi Capital may terminate (i) its obligations under any
covenant contained in Sections 1004 through 1021, (ii) the operation of Section 501(v), Section 501(vi) (with respect only to Significant Subsidiaries), Section 501(vii) (with respect only to Significant Subsidiaries) and 501(viii) and (iii) the
limitations contained in Sections 801(a)(iii) with respect to the outstanding Senior Notes on and after the date the conditions set forth below are satisfied (hereinafter, 

  

 87 








 
“Covenant Defeasance”), and the Senior Notes shall thereafter be deemed not to be “outstanding” for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Senior
Notes will not be outstanding for accounting purposes). If DDi Capital exercises its covenant defeasance option, payment of the Senior Notes may not be accelerated because of an Event of Default specified under Section 501(iii), (v), (vi) (with
respect only to Significant Subsidiaries), (vii) (with respect only to Significant Subsidiaries) and (viii) or because of the failure of DDi Capital to comply with Section 801(a)(iii). For this purpose, such Covenant Defeasance means that, with
respect to the outstanding Senior Notes, DDi Capital may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 501(iii),
but, except as specified above, the remainder of this Indenture and such Senior Notes shall be unaffected thereby. 
  
 SECTION 1204. Conditions to Legal Defeasance or Covenant Defeasance. 
  
 The following shall be the conditions to application of either Section 1202 or Section 1203 to the outstanding Senior Notes:

  
 (i) DDi Capital shall irrevocably have deposited or caused to
be deposited with the Trustee (or another trustee satisfying the requirements of this Indenture who shall agree to comply with the provisions of this Article Twelve applicable to it) as trust funds in trust money or Government Obligations, such
amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants selected by DDi Capital, to pay the Accreted Value of and interest due on the outstanding Senior Notes on the Stated Maturity or on the
applicable Redemption Date as the case may be, of such Accreted Value or interest on the outstanding Senior Notes; 
  
 (ii) in the case of Legal Defeasance, DDi Capital shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to
the Trustee (which opinion may be subject to customary assumptions and exclusions) confirming that (A) DDi Capital has received from, or there has been published by, the United States Internal Revenue Service a ruling or (B) since the Issue Date,
there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel in the United States (which opinion may be subject to customary assumptions and exclusions) shall
confirm that the Holders of the outstanding Senior Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; 
  
 (iii) in the case of Covenant Defeasance, DDi Capital shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable
to the Trustee confirming that, subject to customary assumptions and exclusions, the Holders of the outstanding Senior Notes 

  

 88 








 
will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to such tax on the
same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
  
 (iv) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or insofar as Events of Default from bankruptcy or
insolvency events are concerned, at any time in the period ending on the 123rd day after the date of deposit; 
  
 (v) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or
instrument (other than this Indenture) to which DDi Capital is a party or by which DDi Capital is bound; 
  
 (vi) DDi Capital shall have delivered to the Trustee an Opinion of Counsel to the effect that, as of the date of such opinion and subject to customary
assumptions and exclusions following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally under any applicable U.S. federal
or state law, and that the Trustee has a perfected security interest in such trust funds for the ratable benefit of the Holders; 
  
 (vii) DDi Capital shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by DDi Capital with the intent
of defeating, hindering, delaying or defrauding any creditors of DDi Capital or others; 
  
 (viii) DDi Capital shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel in the United States (which Opinion of Counsel may be subject to customary assumptions and exclusions)
each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with; and 
  
 (ix) DDi Capital shall have delivered to the Trustee the opinion of a nationally recognized firm of independent public
accountants stating the matters set forth in paragraph (i) above. 
  
 SECTION 1205. Deposited Money and Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. 
  
 Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section 1205, the “Trustee”) pursuant to Section 1204 in respect of the outstanding Senior Notes shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Senior Notes and this Indenture, to the payment, either directly or through any Paying Agent (including DDi Capital acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Senior Notes of all sums
due and to become due thereon in respect of Accreted Value and interest, but such money need not be segregated from other funds except to the extent required by law. 
  

 89 








 DDi Capital shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the Government Obligations deposited pursuant to Section 1204 or the principal and interest received in respect thereof. 
  
 Anything in this Article Twelve to the contrary notwithstanding, the Trustee shall deliver or pay to DDi Capital from time to time upon DDi Capital
Request any money or Government Obligations held by it as provided in Section 1204 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to effect an equivalent legal defeasance or covenant defeasance, as applicable, in accordance with this Article. 
  
 SECTION 1206. Reinstatement. 
  
 If the Trustee or any Paying Agent is unable to apply any money or Government Obligations in accordance with Section 1205 by
reason of any legal proceeding or by any reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then DDi Capital’s obligations under this Indenture and the Senior
Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 1202 or 1203, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 1205;
provided, however, that if DDi Capital makes any payment of Accreted Value of or interest on any Senior Note following the reinstatement of its obligations, DDi Capital shall be subrogated to the rights of the Holders of such Senior Notes to receive
such payment from the money and Government Obligations held by the Trustee or Paying Agent.
