 APPENDIX A 
 TERMS AND CONDITIONS OF RESTRICTED STOCK UNITS 
 1. Grant. The Company hereby grants to the
Employee under the Plan an award of the Number of Restricted Stock Units set forth on the Notice of Grant, subject to all of the terms and conditions in this Agreement and the Plan. When shares of the Company’s Common Stock (“Shares”)
are paid to the Employee in payment for the Restricted Stock Units, par value shall be deemed paid by the Employee for each Restricted Stock Unit by past services rendered by the Employee, and shall be subject to the appropriate tax withholdings.
Unless otherwise defined herein, capitalized terms used herein shall have the meanings ascribed to them in the Plan. 
 2. Company’s
Obligation to Pay. Unless and until the Restricted Stock Units have vested in the manner set forth in paragraphs 3, 4 or 5, the Employee will have no right to payment of such Restricted Stock Units. Prior to actual payment of any vested
Restricted Stock Units, such Restricted Stock Units will represent an unsecured obligation. Payment of any vested Restricted Stock Units shall be made in whole Shares only. 
 3. Vesting Schedule/Period of Restriction. Except as provided in paragraphs 4 or 5, the Restricted Stock Units awarded by this Agreement shall
vest in accordance with the vesting provisions set forth on the first page of this Agreement. Restricted Stock Units shall not vest in the Employee in accordance with any of the provisions of this Agreement unless the Employee shall have been
continuously employed by the Company or by one of its Subsidiaries from the Grant Date until the date the Restricted Stock Units are otherwise scheduled to vest occurs. 
 4. Change in Control. In the event of a Change in Control, this Restricted Stock Unit award shall immediately vest and be settled by the Company through the issuance of Shares immediately prior to the effective
date of the Change in Control unless this Restricted Stock Unit award is otherwise assumed or substituted by the successor corporation (or parent thereof). 
 5. Plan Administrator Discretion. The Plan Administrator, in its discretion, may accelerate the vesting of the balance, or some lesser portion of the balance, of the Restricted Stock Units at any time, subject
to the terms of the Plan. If so accelerated, such Restricted Stock Units will be considered as having vested as of the date specified by the Plan Administrator. If the Plan Administrator, in its discretion, accelerates the vesting of the balance, or
some lesser portion of the balance, of the Restricted Stock Units, the payment of such accelerated Restricted Stock Units nevertheless shall be made at the same time or times as if such Restricted Stock Units had vested in accordance with the
vesting schedule set forth on the first page of this Agreement (whether or not the Employee remains employed by the Company or by one of its Subsidiaries as of such date(s)), unless an earlier payment date, in the judgment of the Plan Administrator,
would not cause the Employee to incur an additional tax under Section 409A of the U.S. Internal Revenue Code of 1986, as amended, and any proposed, temporary or final Treasury Regulations and Internal Revenue Service guidance thereunder
(“Section 409A”). 
  

 -2- 

 6. Payment after Vesting. Any Restricted Stock Units that vest in accordance with paragraph 3 will
be paid to the Employee (or in the event of the Employee’s death, to his or her estate) as soon as practicable following the date of vesting, subject to paragraph 9. Any Restricted Stock Units that vest in accordance with paragraph 5 will
be paid to the Employee (or in the event of the Employee’s death, to his or her estate) in accordance with the provisions of such paragraph, subject to paragraph 9. For each Restricted Stock Unit that vests, the Employee will receive one
Share. 
 7. Forfeiture. Notwithstanding any contrary provision of this Agreement, the balance of the Restricted Stock Units that have
not vested pursuant to paragraphs 3, 4 or 5 at the time of the Employee’s termination of service for any or no reason will be forfeited and automatically transferred to and reacquired by the Company at no cost to the Company. 
 8. Death of Employee. Any distribution or delivery to be made to the Employee under this Agreement will, if the Employee is then deceased, be made
to the administrator or executor of the Employee’s estate. Any such administrator or executor must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to
establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer. 
 9. Withholding of
Taxes. When Shares are issued as payment for vested Restricted Stock Units, the Company (or the employing Subsidiary) shall withhold a portion of the Shares that have an aggregate market value sufficient to pay the minimum federal, state, local
and foreign income, social insurance, employment and any other applicable taxes required to be withheld by the Company or the employing Subsidiary with respect to the Shares, unless the Company, in its sole discretion, either requires or otherwise
permits the Employee to make alternate arrangements satisfactory to the Company for such withholdings in advance of the arising of any withholding obligations. The number of Shares withheld pursuant to the prior sentence shall be rounded up to the
nearest whole Share, with no refund for any value of the Shares withheld in excess of the tax obligation as a result of such rounding. Notwithstanding any contrary provision of this Agreement, no Shares will be issued unless and until satisfactory
arrangements (as determined by the Company) have been made by the Employee with respect to the payment of any income and other taxes which the Company determines must be withheld or collected with respect to such Shares. In addition and to the
maximum extent permitted by law, the Company (or the employing Subsidiary) has the right to retain without notice from salary or other amounts payable to the Employee, cash having a sufficient value to satisfy any tax withholding obligations that
the Company determines cannot be satisfied through the withholding of otherwise deliverable Shares. All income and other taxes related to the Restricted Stock Unit award and any Shares delivered in payment thereof are the sole responsibility of the
Employee. By accepting this award, the Employee expressly consents to the withholding of Shares and to any additional cash withholding as provided for in this paragraph 9. 
 10. Rights as Stockholder. Neither the Employee nor any person claiming under or through the Employee will have any of the rights or privileges of
a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the Company or its transfer agents
or registrars, and delivered to the Employee (including through electronic delivery to a brokerage account). After such issuance, recordation and delivery, the Employee will have all the rights of a stockholder of the Company with respect to voting
such Shares and receipt of dividends and distributions on such Shares. 
  

 -3- 

 11. No Effect on Employment. Subject to any employment contract with the Employee, the terms of
such employment will be determined from time to time by the Company, or the Subsidiary employing the Employee, as the case may be, and the Company, or the Subsidiary employing the Employee, as the case may be, will have the right, which is hereby
expressly reserved, to terminate or change the terms of the employment of the Employee at any time for any reason whatsoever, with or without good cause. The transactions contemplated hereunder and the vesting schedule set forth on the first page of
this Agreement do not constitute an express or implied promise of continued employment for any period of time. 
 12. Address for
Notices. Any notice to be given to the Company under the terms of this Agreement will be addressed to the Company, in care of the Finance Department, Carrier Access Corporation, 5395 Pearl Parkway, Boulder, CO 80301, or at such other address as
the Company may hereafter designate in writing. 
 13. Grant is Not Transferable. Except to the limited extent provided in this
Agreement, this grant of Restricted Stock Units and the rights and privileges conferred hereby will not be sold, pledged, assigned, hypothecated, transferred or disposed of any way (whether by operation of law or otherwise) and will not be subject
to sale under execution, attachment or similar process, until the Employee has been issued Shares in payment of the Restricted Stock Units. Upon any attempt to sell, pledge, assign, hypothecate, transfer or otherwise dispose of this grant, or any
right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and void. 
 14. Restrictions on Sale of Securities. The Shares issued as payment for vested Restricted Stock Units under this Agreement will be registered
under U.S. federal securities laws and will be freely tradable upon receipt. However, an Employee’s subsequent sale of the Shares may be subject to any market blackout-period that may be imposed by the Company and must comply with the
Company’s insider trading policies, and any other applicable securities laws. 
 15. Binding Agreement. Subject to the limitation
on the transferability of this grant contained herein, this Agreement will be binding upon and inure to the benefit of the heirs, legatees, legal representatives, successors and assigns of the parties hereto. 
 16. Additional Conditions to Issuance of Certificates for Shares. The Company shall not be required to issue any certificate or certificates for
Shares hereunder prior to fulfillment of all the following conditions: (a) the admission of such Shares to listing on all stock exchanges on which such class of stock is then listed; (b) the completion of any registration or other
qualification of such Shares under any U.S. state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory body, which the Plan Administrator shall, in its absolute discretion,
deem necessary or advisable; (c) the obtaining of any approval or other clearance from any U.S. state or federal governmental agency, which the Plan Administrator shall, in its absolute discretion, determine to be necessary or advisable; and
(d) the lapse of such reasonable period of time following the date of vesting of the Restricted Stock Units as the Plan Administrator may establish from time to time for reasons of administrative convenience.

 1. Grant. The Company hereby grants to the
Employee under the Plan an award of [NUMBER] Shares for $0.001 per Share, commencing on the Grant Date, subject to all of the terms and conditions in this Agreement and the Plan. By accepting this grant of Restricted Stock, the par value
purchase price for each Share of Restricted Stock (a) will be deemed paid by the Employee by past services rendered by the Employee, if the Employee is an existing employee of the Company or one of its Subsidiaries and not a newly-hired
employee, or (b) shall be paid to the Company at the time of execution of this Agreement by cash or check by the Employee, if the Employee is a newly-hired employee of the Company or one of its Subsidiaries. Only whole shares shall be issued.

 2. Shares Held in Escrow. Unless and until the Shares will have vested in the manner set forth in paragraphs 3 through 5, such
Shares will be issued in the name of the Employee and held by the [INSERT DEPARTMENT/TITLE] of the Company (or [its] [his or her] designee) as escrow agent (the “Escrow Agent”), and will not be sold, transferred or otherwise
disposed of, and will not be pledged or otherwise hypothecated. The Company may determine to issue the Shares in book entry form and/or may instruct the transfer agent for its Common Stock to place a legend on the certificates representing the
Restricted Stock or otherwise note its records as to the restrictions on transfer set forth in this Agreement and the Plan. The certificate or certificates representing such Shares will not be delivered by the Escrow Agent to the Employee unless and
until the Shares have vested and all other terms and conditions in this Agreement have been satisfied. 
 3. Vesting Schedule/Period of
Restriction. Except as provided in paragraph 4, and subject to paragraph 5, the Shares awarded by this Agreement shall vest in accordance with the vesting provisions set forth on the first page of this Agreement. Shares shall not vest in the
Employee in accordance with any of the provisions of this Agreement unless the Employee shall have been continuously employed by the Company or by one of its Subsidiaries from the Grant Date until the date vesting otherwise is scheduled to occur.

 4. Plan Administrator Discretion. The Plan Administrator, in its discretion, may accelerate the vesting of the balance, or some
lesser portion of the balance, of the unvested Shares at any time, subject to the terms of the Plan. If so accelerated, such Shares will be considered as having vested as of the date specified by the Plan Administrator. 
 5. Forfeiture. Notwithstanding any contrary provision of this Agreement, the balance of the Shares that have not vested at the time of the
Employee’s ceasing to be employed by the Company or by one of its Subsidiaries will be forfeited and automatically transferred to and reacquired by the Company at no cost to the Company upon the date the Employee ceases employment for any
reason. The Employee shall not be entitled to a refund of the price paid for the Shares returned to the Company pursuant to this paragraph 5, unless the Employee paid the par value purchase price of the Shares with cash or check. The Employee hereby
appoints the Escrow Agent with full power of substitution, as the Employee’s true and lawful attorney-in-fact with irrevocable power and authority in the name and on behalf of the Employee to take any action and execute all documents and
instruments, including, without limitation, stock powers which may be necessary to transfer the certificate or certificates evidencing such forfeited Shares to the Company.

 6. Death of Employee. Any distribution or delivery to be made to the Employee under this Agreement
will, if the Employee is then deceased, be made to the administrator or executor of the Employee’s estate. Any such administrator or executor must furnish the Company with (a) written notice of his or her status as transferee,
(b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations pertaining to said transfer, and (c) written acceptance of the terms and conditions of this award of Restricted
Stock as set forth in this Agreement. 
 7. Withholding of Taxes. The Company (or the employing Subsidiary) will withhold a portion of
the Shares that have an aggregate market value sufficient to pay the minimum federal, state, local and foreign income, social insurance, employment and any other applicable taxes required to be withheld by the Company or the employing Subsidiary
with respect to the Shares, unless the Company, in its sole discretion, requires or otherwise permits the Employee to make alternate arrangements satisfactory to the Company for such withholdings in advance of the arising of any withholding
obligations. The number of Shares withheld pursuant to the prior sentence will be rounded up to the nearest whole Share, with no refund for any value of the Shares withheld in excess of the tax obligation as a result of such rounding.
Notwithstanding any contrary provision of this Agreement, no Restricted Stock will be released by the Escrow Agent from escrow unless and until satisfactory arrangements (as determined by the Company) have been made by the Employee with respect to
the payment of any income and other taxes which the Company determines must be withheld or collected with respect to such Shares. In addition and to the maximum extent permitted by law, the Company (or the employing Subsidiary) has the right to
retain without notice from salary or other amounts payable to the Employee, cash having a sufficient value to satisfy any tax withholding obligations that the Company determines cannot be satisfied through the withholding of otherwise deliverable
Shares. All income and other taxes related to the Restricted Stock award and any Shares delivered in payment thereof are the sole responsibility of the Employee. By accepting this award, the Employee expressly consents to the withholding of Shares
and to any additional cash withholding as provided for in this paragraph 7. 
 8. Rights as Stockholder. Neither the Employee nor
any person claiming under or through the Employee will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book

paragraph 10, after such issuance, recordation and delivery, the Employee will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such Shares. 
 9. No Effect on Employment. Subject to any employment contract with the Employee, the terms of such employment will be determined from time to
time by the Company, or the Subsidiary employing the Employee, as the case may be, and the Company, or the Subsidiary employing the Employee, as the case may be, will have the right, which is hereby expressly reserved, to terminate or change the
terms of the employment of the Employee at any time for any 

  

 3 

 
reason whatsoever, with or without good cause. The transactions contemplated hereunder and the vesting schedule set forth on the first page of this Agreement
do not constitute an express or implied promise of continued employment for any period of time. 
 10. Changes in Shares. In the event
that as a result of a stock dividend, stock split, recapitalization, combination of Shares, exchange of Shares or other change affecting the outstanding Common Stock as a class without the Company’s receipt of consideration, the Shares will be
increased, reduced or otherwise affected, and by virtue of any such event the Employee will in his or her capacity as owner of unvested Shares which have been awarded to him or her (the “Prior Shares”) be entitled to new or additional or
different shares of stock, cash (including money paid other than as a regular cash dividend) or other securities or property (other than rights or warrants to purchase securities), such new or additional or different shares, cash or securities or
property will thereupon be considered to be unvested Restricted Stock and will be subject to all of the conditions and restrictions that were applicable to the Prior Shares pursuant to this Agreement and the Plan. If the Employee receives rights or
warrants with respect to any Prior Shares, such rights or warrants may be held or exercised by the Employee, provided that until such exercise any such rights or warrants and after such exercise any shares or other securities acquired by the
exercise of such rights or warrants will be considered to be unvested Restricted Stock and will be subject to all of the conditions and restrictions which were applicable to the Prior Shares pursuant to the Plan and this Agreement. The Plan
Administrator in its absolute discretion at any time may accelerate the vesting of all or any portion of such new or additional shares of Restricted Stock, cash or securities, rights or warrants to purchase securities or shares or other securities
acquired by the exercise of such rights or warrants.

and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon any attempt to
transfer, assign, pledge, hypothecate or otherwise dispose of any unvested Shares subject to this grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the
rights and privileges conferred hereby immediately will become null and void. 
 13. Restrictions on Sale of Securities. The Shares
issued as payment for vested Restricted Stock awarded under this Agreement will be registered under U. S. federal securities laws and will be freely tradable upon receipt. However, an Employee’s subsequent sale of the Shares may be subject to
any market blackout-period that may be imposed by the Company and must comply with the Company’s insider trading policies, and any other applicable securities laws.

 17. Plan Administrator Authority. The Plan Administrator will have the power to interpret the Plan and this Agreement and to adopt such rules for
the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Shares have vested). All actions taken and
all interpretations and determinations made by the Plan Administrator in good faith will be final and binding upon the Employee, the Company and all other interested persons. No member of the Plan Administrator will be personally liable for any
