                                AMENDMENT NO. 2
                                       TO
                                 IRU AGREEMENT

THIS AMENDMENT NO. 2 to IRU Agreement (this "Amendment") is effective as of
June 28th, 2002 (the "Effective Date") by and between QWEST COMMUNICATIONS
CORPORATION ("Qwest") and PAC-WEST TELECOMM, INC. ("Customer"). Qwest and
Customer are sometimes collectively referred to herein as the "Parties."

WHEREAS, Qwest and Customer entered into that certain IRU agreement effective
as of June 30, 2000 (the "Agreement") and thereafter amended the payment terms
of the Agreement by executing Amendment No. 1 to the Agreement effective April
18, 2001.

WHEREAS, the Parties desire to modify the Agreement to reflect new payment
terms for the IRU Fee, as more particularly described below.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
the Parties agree as follows:

1.   Amendment No. 1 to the Agreement is hereby rescinded and replaced in its
     entirety by this Amendment.

2.   The Agreement is hereby amended so as to provide that, notwithstanding
     anything to the contrary in Section 3.1 or elsewhere in the Agreement,
     Customer shall pay to Qwest the balance due of the IRU Fee ($8,619,920)
     according to the following schedule:

          A.   $4,419,920.50 shall be due and payable December 15, 2002; and

          B.   $4,200,000.00 together with interest as provided in Section 3 of
     this Amendment shall be payable May 15, 2003.

3.   The payment due May 15, 2003 shall accrue interest annually from and after
     May 15, 2002, at a variable rate equal to the Prime Rate, as defined

     Street Journal with adjustments in that varying rate to be made on the
     same dates as any change in that rate is so published.

4.   Attached to this Amendment as Exhibit A and incorporated into this
     Amendment by this reference is a Promissory Note (the "Note") providing
     further evidence of Customer's payment obligations that are required under
     the Agreement by virtue of this Amendment. Qwest reserves all of its
     rights under both the Agreement and the Note. The Note is additional
     evidence of Customer's payment obligations under the Agreement and is not
     in dimunition of any rights or obligations of the parties under the
     Agreement. Qwest may enforce its remedies under the Agreement, or under
     the Note, or under both, in any sequence, in Quest's sole discretion, but
     is entitled only to a single satisfaction of the payment obligations.

5.    Section 13 of the Agreement shall be deleted in its entirety and replaced
      with the following Section 13:

"13.  CHARACTERIZATION OF TRANSACTION

13.1  Subject to Section 5.3 above, the parties intend that each IRU granted in
this Agreement does not provide Customer with any ownership or other possessory
interests in any real property, conduit, fiber, or equipment in or on the Qwest
Network or along the User Route of the Qwest Network (the "Physical Assets").
Further, it is not the intention of the parties to create a loan or other
financing arrangement between the parties. However, to secure payment of the IRU
Fee and in the event the express intent of the parties is not given legal effect
and that any portion of the transaction is deemed to constitute a loan or other
financing arrangement, or that any right in the IRU(s) granted herein are deemed
to create rights in the Physical Assets, Customer hereby grants to Qwest, as
security for the payment of all amounts due from Customer and the performance of
all other obligations of Customer hereunder, a first-priority security interest
in and continuing lien upon all of Customer's rights (including any right
Customer may have to convey title thereto), title and interest in: (i) the
granted IRU(s), and (ii) all rights of Customer under this Agreement
("Collateral"). Customer covenants that Qwest will have a first-priority
security interest in and continuing lien upon all of the Collateral. Customer's
breach of its covenant in this Section 13.1 shall be deemed a default of this
Agreement in accordance with Article 17 of the Agreement for which Qwest will be
entitled to terminate Customer's rights in and to the IRU(s) granted hereunder
and shall further be entitled to exercise all the rights and remedies of a
secured party under the Uniform Commercial Code. Upon payment in full of the IRU
Fee, Qwest will file all necessary documents to release its lien on the
Collateral."

6.    The Agreement and this Amendment shall constitute the complete agreement
      of the Parties concerning the subject matter hereof, and supersede any
      prior written or verbal statements, representations, and agreements
      concerning the subject matter hereof. Except as expressly modified by this
      Amendment, the Agreement is and will remain in full force and effect in
      accordance with its terms and constitutes the legal and binding
      obligations of the Parties.

Demand Promissory Note of even date ("Note"). This Pledge Agreement provides the

     NOW, THEREFORE, in consideration of the premises contained herein and other
good and valuable consideration the receipt and sufficiency of which are hereby
acknowledged, and in order to induce the Company to make the loan evidenced by
the Note, Pledgor and the Company hereby agree as follows:

     1.   Pledge. Pledgor hereby pledges to the Company, and grants to the
Company a security interest in, the Pledged Shares as security for the prompt
and complete payment when due of the unpaid principal of and interest on the
Note and full payment and performance of the obligations and liabilities of
Pledgor hereunder.

Pledged Shares, together with duly executed forms of assignment sufficient to
transfer title thereto to the Company.

     3.   Voting; Cash Dividends. Notwithstanding anything to the contrary
contained herein, during the terms of the Pledge Agreement until such time as

any other default under the Note or hereunder, Pledgor shall be entitled to all
voting rights with respect to the Pledged Shares and shall be entitled to
receive all cash dividends paid in respect to the Pledged Shares. Upon the
occurrence of and during the continuance of any such default, Pledgor shall no
longer be able to vote the Pledged Shares and the Company shall retain all such
cash dividends payable on the Pledged Shares as additional security hereunder.

     4.   Stock Dividends; Distributions, etc. If, while this Pledge Agreement
is in effect, Pledgor becomes entitled to receive or receives any securities or
other property in addition to, in substitution of, or in exchange for any of the
Pledged Shares (whether as a distribution in connection with any
recapitalization, reorganization or reclassification, a stock dividend or
otherwise), Pledgor shall accept such securities or other property on behalf of
and for the benefit of the Company as additional security for Pledgor's
obligation under the Note and shall promptly deliver such additional security to
the Company together with duly executed forms of assignment, and such additional
security shall be deemed to be part of the Pledged Shares hereunder.

     5.   Default. If Pledgor defaults in the payment of the principal or
interest under the Note when it becomes due (whether upon demand, acceleration
or otherwise) or any other event of default under the Note or this Pledge

company may exercise any and all rights, powers and remedies of any owner of the
Pledged Shares (including the right to vote the shares and receive dividends and
distributions with respect to

                                       1

<PAGE>
such shares) and shall have and may exercise without demand any and all rights

applicable law. Without limiting the foregoing, the Company is authorized to
sell, assign and deliver at its discretion, from time to time, all or any part
of the Pledged Shares at any private sale or public auction, on not less than
ten days written notice to Pledgor, at such price or prices and upon such terms
and the Company may deem advisable. Pledgor shall have no right to redeem the
Pledged Shares after any such sale or assignment. At any such sale or auction,
the Company may bid for, and become the purchaser of, the whole or any part of
the Pledged Shares offered for sale. In case of any such sale, after deducting
the costs, attorneys' fees and other expenses of sale and delivery, the
remaining proceeds of such sale shall be applied to the principal of and accrued
interest on the Note; provided that after payment in full of the indebtedness
evidenced by the Note, the balance of the proceeds of the sale then remaining
shall be paid to Pledgor and Pledgor shall be entitled to the return of any of
the Pledged Shares remaining in the hands of the Company. Pledgor shall be
liable for any deficiency if the remaining proceeds are insufficient to pay the
indebtedness under the Note in full, including the fees of any attorneys
employed by the Company to collect such deficiency.

     6.   Costs and Attorneys' Fees. All costs and expenses (including
reasonable attorneys' fees) incurred in exercising any right, power or remedy
conferred by this Pledge Agreement or in the enforcement thereof, shall become
part of the indebtedness secured hereunder and shall be paid by Pledgor or
repaid from the proceeds of the sale of the Pledged Shares hereunder. In the
event a court of competent jurisdiction determines that his Pledge Agreement is
not yet enforceable or is otherwise unenforceable at any time when enforcement
is sought by the Company, the company shall pay all reasonable costs and
attorneys fees of Pledgor incurred in connection with such attempted
enforcement.

     7.   Payment of Indebtedness and Release of Pledged Shares.  Upon payment
in full of the indebtedness evidenced by the Note, the company shall surrender
the Pledged Shares to Pledgor together with all forms of assignment.

     8.   No Other Liens, No Sales or Transfers. Pledgor hereby represents and
warrants that he has good and valid title to all of the Pledge Shares, free and
clear of all liens, security interests and other encumbrances, and Pledgor
hereby covenants that, until such time as all of the outstanding principal of
and interest on the Note has been repaid, Pledgor shall not (i) create, incur,
assume or suffer to exist any pledge, security interest, encumbrance, lien or
charge of any kind against the Pledged Shares or Pledgor's rights or a holder
thereof, other than pursuant to this Agreement, or (ii) sell or otherwise
transfer any Pledged Shares or any interest therein.

     9.   Further Assurances. Pledgor agrees that at any time and from time to

     NOW, THEREFORE, in consideration of the premises contained herein and
other good and valuable consideration the receipt and sufficiency of which are
hereby acknowledged, and in order to induce the Company to make the loan
evidenced by the Note, Pledgor and the Company hereby agree as follows:

     1.   Pledge. Pledgor hereby pledges to the Company, and grants to the
Company a security interest in, the Pledged Shares as security for the prompt
and complete payment when due of the unpaid principal of and interest on the
Note and full payment and performance of the obligations and liabilities of
Pledgor hereunder.

Pledged Shares, together with duly executed forms of assignment sufficient to
transfer title thereto to the Company.

     3.   Voting: Cash Dividends. Notwithstanding anything to the contrary

any other default under the Note or hereunder, Pledgor shall be entitled to all
voting rights with respect to the Pledged Shares and shall be entitled to
receive all cash dividends paid in respect to the Pledged Shares. Upon the
occurrence of and during the continuance of any such default, Pledgor shall no

cash dividends payable on the Pledged Shares as additional security hereunder.

     4.   Stock Dividends; Distributions, etc. If, while this Pledge Agreement

other property in addition to, in substitution of, or in exchange for any of
the Pledged Shares (whether as a distribution in connection with any
recapitalization, reorganization or reclassification, a stock dividend or
otherwise), Pledgor shall accept such securities or other property on behalf of
and for the benefit of the Company as additional security for Pledgor's
obligation under the Note and shall promptly deliver such additional security

the Pledged Shares (including the right to vote the shares and distributions

ten days written notice to Pledgor, at such price or prices and upon such terms
and the Company may deemed advisable. Pledgor shall have no right to redeem the
Pledged Shares after any such sale or assignment. At any such sale or auction,
the Company may bid for, and become the purchaser of, the whole or any part of
the Pledged Shares offered for sale. In case of any such sale, after deducting
the costs, attorneys' fees and other expenses of sale and delivery, the
remaining proceeds of such sale shall be applied to the principal of and accrued

be paid to Pledgor and Pledgor shall be entitled to the return of any of the
Pledged Shares remaining in the hands of the Company. Pledgor shall be liable
for any deficiency if the remaining proceeds are insufficient to pay the
indebtedness under the Note in full, including the fees of any attorneys
employed by the Company to collect such deficiency.

     6.   Costs and Attorneys' Fees. All costs and expenses (including
reasonable attorneys' fees) incurred in exercising any right, power or remedy
conferred by this Pledge Agreement or in the enforcement thereof, shall become
part of the indebtedness secured hereunder and shall be paid by Pledgor or
repaid from the proceeds of the sale of the Pledged Shares hereunder. In the
event a court of competent jurisdiction determines that this Pledge Agreement is
not yet enforceable or is otherwise unenforceable at any time when enforcement
is sought by the Company, the company shall pay all reasonable costs and
attorneys fees of Pledgor incurred in connection with such attempted
enforcement.

     7.   Payment of Indebtedness and Release of Pledged Shares.  Upon payment
in full of the indebtedness evidenced by the Note, the company shall surrender
the Pledged Shares to Pledgor together with all forms of assignment.

     8.   No Other Liens, No Sales or Transfers. Pledgor hereby represents and
warrants that he has good and valid title to all of the Pledge Shares, free and
clear of all liens, security interests and other encumbrances, and Pledgor
hereby covenants that, until such time as all of the outstanding principal of
and interest on the Note has been repaid, Pledgor shall not (i) create, incur,
assume or suffer to exist any pledge, security interest, encumbrance, lien or
charge of any kind against the Pledged Shares or Pledgor's rights or a holder
thereof, other than pursuant to this Agreement, or (ii) sell or otherwise
transfer any Pledged Shares or any interest therein.

     9.   Further Assurances. Pledgor agrees that at any time and from time to
time upon the written request of the Company, Pledgor shall execute and deliver
such further documents (including UCC financing statements) and do such further
acts and things as the Company may reasonably request in order to effect the
purposes of this Pledge Agreement.

prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.
