as (i) no Default or Matured Default has occurred or would occur as a result of or immediately following any such payment, (ii) the Borrower has maintained Working Capital in an amount equal to or greater than $15,000,000 for two
consecutive fiscal quarters following the funding of a Support Term Loan, and (iii) Working Capital of the Borrower will continue to equal or exceed $15,000,000 after giving effect to any such payment; and

forma basis, after giving effect to any such payment.

 Notwithstanding the foregoing, no
principal, interest or other payment shall be made by the Borrower or accepted by the Parent in respect of any Subordinated Obligation during the continuance of any Default or Matured Default. 

5.        Turnover of Prohibited Payments. If the Parent receives any payment in respect
of any Subordinated Obligation that the Parent is not entitled to receive under the provisions of this Agreement, the Parent will hold the amount so received in trust for the Senior Lender Parties and will forthwith turn over such payment to the
Agent in the form received (except for the endorsement of the Parent where necessary) for application to then-existing Senior Obligations (whether or not due), in such order and manner of application as the Agent may deem appropriate in its sole
discretion. If the Parent exercises any right of setoff which the Parent is not permitted to exercise under the provisions of this Agreement, the Parent will promptly pay over to the Agent, in immediately available funds, an amount equal to the
amount of the claims or obligations offset. If the Parent fails to make any endorsement required under this Agreement, the Agent, or any of its officers, employees or agents on behalf of the Agent, is hereby irrevocably appointed as the
attorney-in-fact (which appointment is coupled with an interest) for the Parent to make such endorsement in the Parent’s name. 
 6.        No Action on Subordinated Obligations. The Parent will not commence any action or proceeding against the Borrower to recover all or any part of the
Subordinated Obligations, or join with any creditor (unless the Senior Lender Parties shall so join) in bringing any Proceeding against the Borrower under the Bankruptcy Code, any other Bankruptcy Law or any other applicable law, or take possession
of, sell, or dispose of any Collateral or any other asset of the Borrower, or exercise or enforce any other right or remedy available to the Parent with respect to the Borrower, any of the Collateral or any other asset of the Borrower, unless and
until the Senior Obligations have been Paid in Full. 
 7.        No Liens in
Collateral or Other Assets of the Borrower. 
 (a)        The Parent
agrees that it will not obtain or accept any Lien in any of the Collateral or in any other asset of the Borrower. 
 (b)        If the Parent breaches its agreement in clause (a) above (and without limiting any claims or causes of action or other remedies which the Senior
Lender Parties may have against the Parent for such breach), notwithstanding any Lien now held or hereafter acquired by the Parent in the Collateral or in any other asset of the Borrower, the Agent or any other Senior Lender Party may take
possession of, sell, dispose of, and otherwise deal with all or any part of the Collateral and any other assets of the Borrower, and may enforce any right or remedy available to them with respect to the Borrower, any Collateral and any other asset
of the Borrower, all without notice to or consent of the Parent except as specifically required by applicable law. In addition, and without limiting the generality of the foregoing, if the Parent has a Lien in any Collateral or in any of other
assets of the Borrower in violation of clause (a) above, the Parent hereby irrevocably consents to any sale or disposition by the Borrower of any of the Collateral or any of the other assets of the Borrower which has been consented to by the
Agent free and clear of any such Lien of the Parent. Upon request of the Agent, the Parent shall immediately execute and deliver to the Agent such releases and terminations (and any related 

  
 -6-









 
financing statements such as “in-lieu” financing statements under Part 7 of Article 9 of the Uniform Commercial Code) as the Agent shall request with respect to any Lien which the
Parent may have obtained or accepted in any of the Collateral or in any other asset of the Borrower. The Parent hereby irrevocably appoints the Agent, or any of its officers, employees or agents on behalf of the Agent, as its attorney-in-fact (which
appointment is coupled with an interest) for the purpose of executing and filing such releases or terminations with respect to any of the Collateral or any other asset of the Borrower. 

(c)        The Senior Lender Parties shall have no duty to preserve, protect, care
for, insure, take possession of, collect, dispose of, or otherwise realize upon any of the Collateral or any of the other assets of the Borrower, and in no event shall the Senior Lender Parties be deemed the Parent’s agent with respect to the
Collateral or any of the other assets of the Borrower. All proceeds received by the Senior Lender Parties with respect to any Collateral or any other assets of the Borrower may be applied to any of the Senior Obligations in such manner and order of
application that the Agent shall determine in its sole discretion. 

(d)        The Parent agrees that (i) no covenant, agreement or restriction
contained in any of the Loan Documents shall be deemed to prevent, restrain, limit or restrict in any way the rights and remedies of the Senior Lender Parties with respect to the Collateral and the other assets of the Borrower, and (ii) no
covenant, agreement or restriction contained in any of the Loan Documents shall be deemed to prevent, restrain, limit or restrict in any way any sale or other disposition by the Borrower of the Collateral or of any other assets of the Borrower after
the occurrence of a Default or Matured Default if the Agent has consented to such sale or disposition. 

8.        Proceedings. 

(a)        In connection with any Proceeding involving the Borrower or any of its
respective properties or assets, the agreements contained in this Agreement shall remain in full force and effect and enforceable pursuant to their terms in accordance with Section 510(a) of the Bankruptcy Code and in accordance with any other
applicable provision of any Bankruptcy Law, and all references herein to the Borrower shall be deemed to apply to the Borrower as debtor-in-possession and to any trustee or receiver or similar officer for the estate of the Borrower. 

(b)        Notwithstanding any provision of this Agreement to the contrary, in any
Proceeding involving the Borrower or any of its respective properties or assets, (i) all Senior Obligations shall be Paid in Full before any payment or distribution (whether made in cash, securities or other property) shall be made in any such
Proceeding with respect to or on account of any of the Subordinated Obligations, (ii) any payment or distribution which, but for this Agreement, otherwise would be payable or deliverable in any such Proceeding in respect of the Subordinated
Obligations, shall be paid or distributed directly to the Agent to be held and/or applied to the Senior Obligations in such manner and order of application as the Agent shall determine in its sole discretion until all of the Senior Obligations have
been Paid in Full, (iii) the Parent hereby irrevocably authorizes, empowers and directs the Borrower, all debtors-in-possession, 

  
 -7-









 
receivers, trustees, liquidators, custodians, distribution agents, plan representatives, conservators or others having authority to make or otherwise effect any such payments or distributions to
make such payments and distributions directly to the Agent for the benefit of the Senior Lender Parties, and the Parent also hereby irrevocably authorizes and empowers the Agent to demand, sue for, collect and receive each such payment or
distribution, (iv) the Parent agrees to execute and deliver to the Agent all such further documents or instruments as may be reasonably requested by the Agent with respect to the authorizations described in clause (iii) of this
Section 8(b), and (v) the Parent hereby irrevocably appoints the Agent, or any of its officers, employees or agents on behalf of the Agent, as the attorney-in-fact (which appointment is coupled with an interest) for the Parent with the
power to execute, prepare, verify, deliver and file proofs of claim or similar documents in respect of the Subordinated Obligations in connection with any Proceeding and to vote the claims of the Parent in connection with any Proceeding;
provided, however, none of the Senior Lender Parties shall have any obligation or duty to execute, prepare, verify, deliver and/or file any such proof of claim or similar document in any Proceeding or to vote any claim of the Parent in
any Proceeding and the action or inaction of the Senior Lender Parties shall not give rise to any claims or liability against any of the Senior Lender Parties. In the event that, notwithstanding the foregoing, any payment or distribution of assets
or securities, or the proceeds of any thereof, shall be collected or received by the Parent in contravention of this provision or any other provisions of this Agreement, such payment or distribution shall be received in trust by the Parent (without
commingling with other funds) for the benefit of the Senior Lender Parties and the Parent shall forthwith deliver such payment or distribution to the Agent for the benefit of the Senior Lender Parties for application to the payment of the Senior
Obligations in such order and manner of application as the Agent shall determine in its sole discretion. 

(c)        The Senior Obligations shall continue to be treated as Senior
Obligations and the provisions of this Agreement shall continue to govern the relative rights and priorities of the Senior Lender Parties and the Parent even if all or any part of the Senior Obligations is subordinated, set aside, avoided or
disallowed in connection with any Proceeding or if any interest, fees, expenses or other amounts accruing with respect to the Senior Obligations following the commencement of any Proceeding is otherwise disallowed or even if all or any part of the
Liens in the Collateral securing the Senior Obligations are subordinated, set aside, avoided or disallowed in connection with any Proceeding. To the extent that any of the Senior Lender Parties receives any payments on or in respect of the Senior
Obligations, including, without limitation, from proceeds of the Collateral, which are subsequently invalidated, declared to be fraudulent or preferential, avoided, set aside and/or required to be repaid to the Borrower, trustee, receiver or any
other party in any Proceeding or otherwise under any Bankruptcy Law, other applicable law, common law, equitable cause, or otherwise, then, to the extent of such payments received, the Senior Obligations, or part thereof, which had been repaid with
such payments shall be automatically reinstated and shall not be or considered Paid in Full and all Senior Obligations and all related Liens in the Collateral shall be reinstated and shall continue in full force and effect as if such payments had
not been received by the Senior Lender Parties.

14.        Cumulative Rights; No Waivers. Each and every right, remedy and power granted
to the Agent or the other Senior Lender Parties hereunder shall be cumulative and in addition to any other right, remedy or power specifically granted herein, in Loan Documents or now or hereafter existing in equity, at law, by virtue of statute or
otherwise, and may be exercised by the Agent or the other Senior Lender Parties, from time to time, concurrently or independently and as often and in such order as the Agent or the other Senior Lender Parties may deem expedient. Any failure or delay
on the part of the Agent or the other Senior Lender Parties in exercising any such right, remedy or power, or abandonment or discontinuance of steps to enforce the same, shall not operate as a waiver thereof or affect the Agent’s or the other
Senior Lender Parties’ right thereafter to exercise the same, and any single or partial exercise of any such right, remedy or power shall not preclude any other or further exercise thereof or the exercise of any other right, remedy or power,
and no such failure, delay, abandonment or single or partial exercise of the Agent’s or the other Senior Lender Parties’ rights hereunder shall be deemed to establish a custom or course of dealing or performance among the parties hereto.

 15.        Further Assurances. The Parent at any time, and from time to time,
after the execution and delivery of this Agreement, upon the request of the Agent and at the expense of the Parent, will promptly execute and deliver such further documents and do such further acts and things as the Agent may reasonably request in
order to fully effect the purposes of this Agreement. 
 16.        Costs and
Expenses. Without limiting Section 10.4 of the Loan Agreement and Section 20 of the Forbearance Agreement, the Parent agrees to pay all reasonable out-of-pocket costs, fees and expenses incurred by the Agent and its Affiliates
(including, without limitation, the reasonable fees, charges and disbursements of counsel, consultants and other agents) in connection with the preparation, negotiation, administration and enforcement of this Agreement or any amendments,
modifications or waivers of the provisions hereof. 
 17.        Successors and
Assigns. This Agreement and the terms, covenants and conditions hereof shall be binding upon and inure to the benefit of the Agent and the Parent, and their respective successors and assigns; provided, however, the Parent shall not
sell, assign, dispose of, transfer, grant a Lien in or permit the Refinancing of all or any portion of the Subordinated Obligations unless and until (i) the Agent, in its sole discretion, shall have given its prior written consent to such sale,
assignment, disposition, transfer, grant of Lien or Refinancing, and (ii) such purchaser, assignee, other transferee or Refinancing party shall have expressly acknowledged in writing, pursuant to a written acknowledgment acceptable to the
Agent, that the Subordinated Obligations remain subject to the terms and conditions of this Agreement and such purchaser, assignee, other transferee or other Refinancing Party shall have agreed that it is bound by this Agreement and has assumed all
of the responsibilities and obligations of the Parent under this Agreement. The Parent further agrees that if the Borrower Refinances all or any portion of the Senior Obligations, upon request of the Agent or the Borrower, the Parent shall enter
into a replacement subordination agreement with such lender or lenders providing such Refinancing, with such replacement subordination agreement having terms and conditions substantially identical to the terms and conditions of this Agreement.

 18.        Modification. Any modification or waiver of any provision of this
Agreement, or any consent to any departure by the Agent or the Parent therefrom, shall not be

effective in any event unless the same is in writing and signed by the Agent, and then such modification, waiver or consent shall be effective only in the specific instance and for the specific
instance and for the specific purpose given. Any notice to or demand on the Parent in any event not specifically required of the Agent hereunder shall not entitle the Parent to any other or further notice or demand in the same, similar or other
circumstances unless specifically required hereunder. 

19.        Miscellaneous. This Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same instrument. Wherever possible, each provision of this Agreement shall be interpreted
in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Agreement. 

20.        Governing Law; Jurisdiction. This Agreement shall be governed by the internal
laws of the State of Colorado. The Parent irrevocably (a) agrees that any suit, action or other legal proceeding arising out of or relating to this Agreement may be brought in a court of record in the City or the County of Denver, Colorado or
in the Courts of the United States located in the State of Colorado, (b) consents to the jurisdiction of each such court in any suit, action or proceeding, (c) waives any objection which it may have to the laying of venue of any such suit,
action or proceeding in any such courts and any claim that any such suit, action or proceeding has been brought in an inconvenient forum, and (d) agrees that a final judgment in any such suit, action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. 

21.        Waiver of Jury Trial. EACH PARTY HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO
TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF, BASED ON OR PERTAINING TO THIS AGREEMENT.
