<PAGE>

      10.   Telecommunications.
            ------------------
            (a) Limitation of Responsibility. Tenant acknowledges and agrees
that all telephone and telecommunications services desired by Tenant for use in
the Premises shall be ordered and utilized at the sole cost and expense of
Tenant. Subject to Landlord's supervision and approval, Tenant shall have the
right to use the riser cables by installing telecommunication lines from the
Premises to the terminal block on the floor or floors on which the Premises are
located (such lines, and any other voice/data cables, lines or wires used or
installed by or for Tenant and serving the Premises are referred to as the
"telecommunication lines"). Landlord, however, makes no representations or
warranties with respect to the capacity, suitability or design of the riser
cables or terminal blocks. If there is more than one tenant on a floor, Landlord
will allocate hook-ups to the terminal block based on the proportion of rentable
square feet that each tenant occupies on the floor. The installation and hook-up
of telecommunication lines by Tenant will be subject to all of the terms and
conditions of this Lease, including, without limitation, Paragraph 20 of this
Lease. Tenant will have no rights or interest in the riser cables and terminal
blocks in the Building therein except as set forth herein. Under no
circumstances will Landlord or its agents or employees be liable for, and Tenant
and each of its subtenants waives all claims with respect to, any damages or
losses sustained by it or any occupant of the Premises, including any property
or consequential damages, resulting from operating or maintenance of the riser
cables and terminal blocks. Without limiting the generality of the foregoing, in
no event shall Landlord be liable for: (a) any damage to Tenant's or its
subtenants' telephone lines, telephones or other equipment connected to the
telecommunication lines; (b) interruption or failure of, or interference with,
telephone or other service coming through the telecommunication lines to the
Premises; or (c) unauthorized eavesdropping or wiretapping. All telephone and
telecommunications desired by Tenant must be ordered and utilized at the sole
expense of Tenant. All of Tenant's telecommunications equipment affixed to the
Premises must be and remain solely in the Premises, in accordance with this
Lease and with the rules and regulations adopted by Landlord from time to time.
Unless otherwise specifically agreed to in writing, Landlord shall have no
responsibility for the maintenance of Tenant's telecommunications equipment,
including wiring, nor for any wiring or other infrastructure to which Tenant's
telecommunications equipment may be connected. Tenant agrees that, to the extent
any such service is interrupted, curtailed or discontinued, Landlord shall have
no obligation or liability with respect thereto and it shall be the sole
obligation of Tenant at its expense to obtain substitute service.

            (b) Necessary Service Interruptions. Landlord shall have the right,
upon reasonable prior notice to Tenant, to interrupt or turn off
telecommunications facilities in the event of emergency or as necessary in
connection with repairs to the Building or installation of telecommunications
equipment for other tenants of the Building, but Landlord shall use commercially
reasonable efforts to restore such services as soon as practicable.

            (c) Removal of Equipment, Wiring and Other Facilities. Any and all
telecommunications equipment installed in the Premises or elsewhere in the
Building by or on behalf of Tenant, including wiring, or other facilities for
telecommunications transmittal, shall be removed prior to the expiration or
earlier termination of the Lease Term, by Tenant at its sole cost or, at
Landlord's election, by Landlord at Tenant's sole cost, with the cost thereof to
be paid as Additional Rent. Landlord shall have the right, however, upon written
notice to Tenant to require Tenant to abandon and leave in place, without
additional payment to Tenant or credit against Rent, any and all
telecommunications wiring and related infrastructure, or selected components
thereof, whether located in the Premises or elsewhere in the Building. Tenant
covenants that Tenant shall be the sole owner of such wiring and related
infrastructure and shall have good right to surrender said wiring and related
infrastructure, which shall at such time be free of all liens and encumbrances
and shall be in working order.

            (d) New Provider Installations. In the event that Tenant wishes at
any time to utilize the services of a telephone or telecommunications provider
whose equipment is not then servicing the Building, no such provider shall be
permitted to install its lines or other equipment within the Building without
first securing the prior written approval of the Landlord, which approval may be
withheld in Landlord's sole and absolute discretion. Landlord's approval shall
not be deemed any kind of warranty or representation by Landlord, including,
without limitation, any warranty or
<PAGE>

representation as to the suitability, competence, or financial strength of the
provider. Without limitation of the foregoing standard, unless all of the
following conditions are satisfied to Landlord's satisfaction, Landlord shall
decline to give its approval:

                  (i) Landlord shall incur no expenses whatsoever with respect
      to any aspect of the provider's provision of its services, including
      without limitation, the costs of installation, materials, services and
      supervision;

                  (ii) Prior to commencement of any work in or about the
      Building by the provider, the provider shall supply Landlord with such
      written indemnities, insurance, financial statements, and such other items
      as Landlord determines to be necessary to protect its financial interests
      and the interests of the Building relating to the proposed activities of
      the provider;

                  (iii) The provider agrees to abide by such rules and
      regulations, building and other codes, job site rules and such other
      requirements as are determined by Landlord to be necessary to protect the
      interests of the Building, the tenants in the Building and Landlord, in
      the same or similar manner as Landlord has the right to protect itself and
      the Building with respect to proposed alterations;

                  (iv)  Landlord  reasonably  determines  that  there is
      sufficient  space  in  the  Building  for  the  placement  of  the
      provider's equipment and materials;

                  (v) The provider agrees to abide by Landlord requirements, if
      any, that provider use existing building conduits and pipes or use
      building contractors (or other contractors approved by Landlord);

                  (vi) Landlord receives from the provider such compensation as
      is determined by Landlord to compensate it for space used in the Building
      for the storage and maintenance of the provider's equipment, for the fair
      market value of a provider's access to the Building, and the costs which
      may reasonably be expected to be incurred by Landlord;

                  (vii) The provider agrees to deliver to Landlord detailed
      "as-built" plans as soon as possible, but in no event later than sixty
      (60) days after the installation of the provider's equipment is complete;
      and

                  (viii) All of the foregoing matters are documented in a
      written license agreement between Landlord and the provider, the form and
      content of which is reasonably satisfactory to Landlord.

            (e) Limit of Default or Breach. Notwithstanding any provision of the
proceeding paragraphs to the contrary, the refusal of Landlord to grant its
approval to any prospective telecommunications provider shall not be deemed a
default or breach by Landlord of its obligation under this Lease unless and
until Landlord is adjudicated to have acted recklessly or maliciously with
respect to Tenant's request for approval, and, in that event, Tenant shall still
have no right to terminate the Lease or claim an entitlement to rent abatement,
but may, as Tenant's sole and exclusive recourse, seek a judicial order of
specific performance compelling Landlord to grant its approval as to the
prospective provider in question. The provisions of this paragraph may be
enforced solely by Tenant and Landlord, are not for the benefit of any other
party (including any subtenant), and specifically, but without limitation, no
telephone or telecommunications provider shall be deemed a third party
beneficiary of this Lease.

            (f) Installation and Use of Wireless Technologies. Tenant shall not
utilize any wireless communications equipment (other than usual and customary
cellular telephones), including antennae and satellite receiver dishes, within
the Premises or the Building, without Landlord's prior written consent. Such
consent may be conditioned in such a manner so as to protect Landlord's
financial interests and the interests of the Building, and the other tenants
therein, in a manner similar
<PAGE>
to the arrangements described in the immediately preceding paragraphs.

            (g) Limitation of Liability for Equipment Interference. In the event
that telecommunications equipment, wiring and facilities or satellite and
antennae equipment of any type installed by or at the request of Tenant within
the Tenant's Premises, on the roof, or elsewhere within or on the Building
causes interference to equipment used by another party, Tenant shall assume all
liability related to such interference. Tenant shall use reasonable efforts, and
shall cooperate with Landlord and other parties, to promptly eliminate such
interference. In the event that Tenant is unable to do so, Tenant will
substitute alternative equipment which remedies the situation. If such
interference persists, Tenant shall discontinue the use of such equipment, and,
at Landlord's discretion, remove such equipment according to foregoing
specifications.

      11.   Right of First Offer.
            --------------------
            The Tenant agrees that Paragraph 3 of the Rider to Lease, which
contains a Right of First Offer, is hereby deleted in its entirety and Landlord
shall have no further obligations thereunder.

      12.   Renewal Term.
            ------------
            The Renewal Option in Paragraph 2 of the Rider to Lease, if
exercised, shall also apply to Suite 1300.

            ---------
            Tenant represents and warrants that it has dealt with no broker,
agent or other person in connection with this transaction, except for Jones Lang
LaSalle Americas (Colorado) L.P., and that no other broker, agent or other
person brought about this transaction, and Tenant agrees to indemnify and hold
Landlord harmless from and against any claims by any other broker, agent or
other person claiming a commission or other form of compensation by virtue of
having dealt with Tenant with regard to this leasing transaction.

      14.   Security Deposit.
            ----------------
            Tenant, concurrently with the execution of this Amendment, hereby
deposits an additional Ten Thousand and No/100 Dollars ($10,000.00) with
Landlord pursuant to Paragraph 33 of the Lease as additional security for the
performance of its obligations under the Lease.

      15.   Authority.
            ---------
            Each of Landlord and Tenant, and each person signing for them,
hereby warrants and represents to the other that the individual signing on
behalf of that party is fully authorized to sign on behalf of, and to bind, such
party and that, when signed by the parties, this Amendment to Lease shall be
fully binding on the party on whose behalf this Amendment to Lease is executed
by such individual.

      16.   Entire Agreement.
            ----------------
            This Amendment to Lease represents the entire agreement of Landlord
and Tenant with regard to the Amendment to Lease, with all prior writings and
verbal negotiations with regard thereto being merged herein.

            Except as modified herein, the provisions of the Lease, as amended,
shall continue in full force and effect.

            In the event of any inconsistency or conflict between the terms and
provisions of the Amendment to Lease and those of the Lease, as amended, the
terms and provisions of the Amendment to Lease shall control.

                              WORKLETTER AGREEMENT
                                  (Suite 1300)

     THIS WORKLETTER is dated _________________, 2000, by and between THE
REGENTS OF THE UNIVERSITY OF COLORADO, a body corporate, for and on behalf of
the University of Colorado at Denver ("Landlord") and MATRIX BANCORP, a Colorado
corporation ("Tenant").
                                R E C I T A L S:

     1. This Workletter is attached to and forms a part of that certain Lease
with a reference date of 1999, as amended ("Lease"), pursuant to which Landlord
has leased to Tenant office space in that building known as Lawrence Street
Center, Denver, Colorado.

     2. The parties have agreed to make certain improvements to the Premises,
upon the terms and conditions contained in the Lease and this Workletter.

     3. Tenant Improvements. Landlord has granted to Tenant an allowance of up
to Sixteen and No/100 Dollars ($16.00) per rentable square foot for Suite 1300,
for a total allowance of up to Seventy-Six Thousand Seven Hundred Fifty-Two and
No/100 Dollars ($76,752.00) (the "Tenant Improvement Allowance"), for completion
of slab-to-slab Tenant Improvements in accordance with the Space Plan. Except as
provided herein, the Tenant Improvement Allowance is for Tenant Improvements in
the Premises. In the event the Tenant Improvement Allowance is not used on or
before December 31, 2000, Landlord shall retain such unused portion of the
Tenant Improvement Allowance, and Tenant shall have no further rights thereto or
hereunder. In the event that the cost of the Tenant Improvements exceeds the
Tenant Improvement Allowance, Landlord shall, at Tenant's written option,
provide Tenant with an additional allowance, above the Tenant Improvement
Allowance, to apply towards payment of the excess costs of the Tenant
Improvements (the "Excess Allowance"), and Tenant shall deposit with Landlord
funds sufficient to cover any additional projected excess costs and promptly pay
to Landlord any costs in excess thereof. Notwithstanding the above, the Excess
Allowance shall not exceed Five Dollars ($5.00) per rentable square foot for
Suite 1300. Any portion of the Excess Allowance paid by Landlord shall either be
(i) amortized on a straight-line basis over the remaining rent paying term of
the Lease, with interest at the rate of Twelve Percent (12%) per annum, payable
by Tenant to Landlord as additional rent, or (ii) paid for directly by the
Tenant. Upon completion, Tenant agrees to execute the Lease Commencement Date
Statement attached hereto as Appendix B. Landlord shall have the work depicted
in the Tenant Space Plan attached hereto as Appendix A (the "Tenant Work")
constructed with, unless otherwise specified, building standard materials and in
a good and workmanlike manner pursuant to the schedule provided for herein,
subject, however, to extensions equal to the delays suffered by Landlord and
caused by Tenant or by strike, lockouts, fire or other casualty loss, acts of
God, unavailability of materials, hostile or war-like action, riot or other
causes beyond Landlord's reasonable control. The Tenant Work, as modified from
time to time pursuant to the provisions of this Workletter, shall be known as
the "Tenant Improvements". The cost of preparing the Space Plan and any other
architectural or engineering fees shall be paid for out of the Tenant
Improvement Allowance as part of the costs of the Tenant Improvements. Landlord
agrees to pay Tenant's contractor directly by paying Fifty Percent (50%) of the
invoices presented and the remaining Fifty Percent (50%) after Landlord receives
acceptable lien waivers from the contractor and subcontractors.

     4.  Tenant  Space  Plan.  Landlord  and Tenant  hereby  approve the space
         -------------------
layout and improvement  plan for the Premises (the "Space Plan") in accordance
with the construction drawings by Architecture 2000 dated October 5, 2000.

     5. Tenant Working Drawings. Based upon the Tenant Space Plan, Landlord
<PAGE>
will cause working drawings for the improvements to the Premises ("Tenant
Working Drawings") to be prepared and delivered to Tenant within a period as may
be reasonably needed because of the complexity of Tenant's improvements or the
nature of Tenant's non-building standard improvements, if any. The Tenant
Working Drawings will include Tenant's partition layout, ceiling plan,
electrical outlets and switches, telephone outlets, and detailed plans and
specifications for the construction of the improvements called for under this
Workletter. Tenant will furnish Landlord and its planners with all the
information necessary to enable them to complete the Tenant Working Drawings.
The cost of all working drawings for Tenant Improvements will be paid for out of
the Tenant Improvement Allowance as part of the costs of the Tenant
Improvements. Tenant will deliver to Landlord written acceptance or rejection of
any Tenant Working Drawings (initial or revised) within three (3) business days
after Tenant receives any such item. If Tenant rejects the Tenant Working
Drawings (initial or revised), or fails to provide written acceptance or
rejection within said three (3) business day period, Landlord shall not be
obligated to proceed with any improvements of the Premises until such time as
Tenant provides such written acceptance, and any delays in construction as a
result thereof shall be deemed delays caused by Tenant.

     6. Tenant Cost Estimate. Landlord shall also cause a cost estimate for the
improvements to the Premises ("Tenant Cost Estimate") to be prepared and
delivered to Tenant. The Tenant will furnish Landlord and its planners with all
the information necessary to enable them to complete the Tenant Cost Estimate.
The cost of all cost estimates for Tenant Improvements will be paid as part of
the costs of the Tenant Improvements. Tenant will deliver to Landlord written
acceptance or rejection of any Tenant Cost Estimate (initial or revised) within
three (3) business days after Tenant receives any such item. If Tenant rejects
the Tenant Cost Estimate, or fails to provide written acceptance or rejection
within said three (3) business day period, Landlord shall not be obligated to
proceed with any improvements of the Premises until such time as Tenant provides
such written acceptance, and any delays in construction as a result thereof
shall be deemed delays caused by Tenant. If at any time the costs of the Tenant
Improvements as reasonably projected by Landlord exceed the Tenant Improvement
Allowance, Tenant shall pay any such excess to Landlord in a manner reasonably
acceptable to Landlord, and, until such payment, Landlord shall not be obligated
to proceed with any improvements of the Premises, and any delays in construction
as a result thereof shall be deemed delays caused by Tenant.

         Upon written approval of the Tenant Working Drawings and the Tenant
Cost Estimate by Tenant, Landlord and Tenant shall be deemed to have given final
approval to the Working Drawings, and the costs thereof, and Landlord shall be
authorized to proceed with construction.

     7. Change Orders. Tenant may request changes in the work during
construction only by written requests to Landlord's Representative on a form
approved by Landlord. All such changes will be subject to Landlord's prior
written approval, which shall not be unreasonably withheld or delayed. Before
commencing any change, Landlord or Landlord's agent will prepare and deliver to
Tenant, for Tenant's written approval, a change order setting forth the cost of
such change, which will include associated architectural, engineering and
construction contractor's fees. If Tenant fails to approve such change order
within three (3) business days, Landlord will not proceed to perform the change.
If Tenant timely approves such change order, Tenant agrees to pay any amounts
payable by Tenant in connection with the change order in the manner provided in
Paragraph #6 above, to the extent the Tenant Improvement Allowance is exceeded.

     8.  Completion  and  Commencement  of Rent.  The term of the Lease  shall
commence as provided in Section #4 of the Second Amendment.

     9. Failure to Perform. If Landlord delivers to Tenant the Tenant Working
Drawings and/or Tenant Cost Estimate and Tenant fails to accept or reject such
Drawings or Estimate (or revised Drawings and/or Estimate) as provided in
Paragraphs #5 and #6 hereof within the period provided herein, Landlord may, in
its sole discretion, deem Tenant to have approved same, and proceed with
construction.

     10. Construction Administration. Landlord shall coordinate and administer
all activities of contractor(s) in the performance of Tenant's Improvements in
accordance with the plans and
<PAGE>
specifications. Tenant agrees that it will not contract with any contractor,
laborer or material supplier to perform any improvements in the Premises without
providing Landlord with notice ten (10) days prior to any improvements and
requiring said contractor, laborer or material supplier to execute an agreement
acknowledging non-liability for payment by Landlord in accordance with C.R.S.
ss. 38-22-105.5, as amended from time to time.

     11. Miscellaneous.

         (a) Except to the extent otherwise indicated herein, the initially
capitalized terms used in this Workletter Agreement shall have the meaning
assigned to them in the Lease.

         (b) The terms and provisions of this Tenant Workletter are intended to
supplement and are intended as an Amendment to the Lease and are specifically
subject to all the terms and provisions of the Lease. In the event of conflict
between the terms of this Tenant Workletter and the Lease, then the provisions
of the Workletter shall govern.

         (c) Prior to the date the Premises are ready for occupancy Landlord's
contractor and Tenant shall inspect the Premises and jointly complete a "punch
list" of incomplete or defective work, and thereafter Landlord shall exercise
due diligence to cause such punch list items to be completed within thirty (30)
days following the date the Premises are ready for occupancy (except for any
punch list items which, despite due diligence, cannot be completed within said
thirty (30) day period).

         (d) This Tenant Workletter may not be amended or modified other than by
supplemental written agreement executed by authorized representatives of the
parties hereto.

         (e) Landlord shall have the right to issue reasonable construction
rules, regulations and policies. If Tenant contests any of these rules,
regulations, or policies, Landlord agrees to take reasonable steps to modify
such rules, regulation, and policies at Tenant's request, except that Tenant
shall pay directly any related expenses of construction or of consultants due to
said changes to the extent said change exceeds the Tenant Improvement Allowance.

         (f) No waiver of any default of the Tenant hereunder shall be implied
from any omission by the Landlord to take any action on account of such default
if such default persists or be repeated, and no express waiver shall affect any
default other than the default specified in the express waiver, and that only
for the time and to the extent therein stated.

         (g) Except as modified herein, the provisions of the Lease shall
continue in full force and effect.

         (h) Landlord neither warrants nor guarantees the accuracy of any
estimated Costs or Tenant Cost Estimates.

         (i) Time is of the essence in this Workletter Agreement, and the
failure by Tenant to timely respond or perform shall be deemed to be a material
default. Tenant undertakes and agrees to, upon written request, meet or provide
written response, as the case may be, within one business day of such written
request, except as otherwise provided in this Workletter Agreement. Any delay
caused by Tenant's failure to do so shall be deemed to be a delay caused by
Tenant.
