INSTRUCTIONS FOR COVER PAGE

(1)  NAMES AND SOCIAL SECURITY NUMBERS OF REPORTING PERSONS -- Furnish the full
     legal name of each person for whom the report is filed -- i.e., each
     person required to sign the schedule itself -- including each member of a
     group. Do not include the name of a person required to be identified in
     the report but who is not a reporting person. Reporting persons are also
     requested to furnish their Social Security or I.R.S. identification
     numbers, although disclosure of such numbers is voluntary, not mandatory
     (see "Special Instructions for Complying with Schedule 13D" below).

(2)  If any of the shares beneficially owned by a reporting person are held
     as a member of a group and such membership is expressly affirmed, please
     check row 2(a). If the membership in a group is disclaimed or the 
     reporting person describes a relationship with other persons but does
     not affirm the existence of a group, please check row 2(b) [unless a joint
     filing pursuant to Rule 13d-1(f)(1) in which case it may not be 
     necessary to check row 2(b)].

(3)  The 3rd row is for SEC internal use: please leave blank.

(4)  Classify the source of funds or other consideration used or to be used
     in making purchases as required to be disclosed pursuant to Item 3 of
     Schedule 13D and insert the appropriate symbol (or symbols if more than
     one is necessary in row (4):

     CATEGORY OF SOURCE                                             SYMBOL
     Subject Company (Company whose securities are

     Other.......................................................     OO

(5)  If disclosure of legal proceedings or actions is required pursuant
     to either Items 2(d) or 2(e) of Schedule 13D, row 5 should be checked.

(6)  CITIZENSHIP OR PLACE OF ORGANIZATION -- Furnish citizenship if the
     named reporting person is a natural person. Otherwise, furnish place
     of organization. (See Item 2 of Schedule 13D)

(7)  (11), (13)  AGGREGATE AMOUNT BENEFICIALLY OWNED BY EACH REPORTING
     PERSON, ETC. -- Rows (7) through (11) inclusive, and (13) are to be
     completed in accordance with the provisions of Item 5 of Schedule 13D.
     All percentages are to be rounded off to nearest tenth (one place after 
     decimal point).

(12) Check if the aggregate amount reported as beneficially owned in row (11)
     does not include shares which the reporting person discloses in the 
     report but as to which beneficial ownership is disclaimed pursuant to
     Rule 13d-4 [17 CFR 240.13d-4] under the Securities Exchange Act of 1934.

(14) TYPE OF REPORTING PERSON -- Please classify each "reporting person" 
     according to the following breakdown and place the appropriate symbol

     symbols) on the form:

Filing persons may, in order to avoid unnecessary duplication, answer items 
on the schedules (Schedule 13D, 13G or 14D-1) by appropriate cross references 
to an item or items on the cover page(s). This approach may only be used 
where the cover page item or items provide all the disclosure required by the 
schedule item. Moreover, such a use of a cover page item will result in the 
item becoming a part of the schedule and accordingly being considered as 
"filed" for purposes of Section 18 of the Securities Exchange Act or 
otherwise subject to the liabilities of that section of the Act.

Reporting persons may comply with their cover page filing requirements by 
filing either completed copies of the blank forms available from the 
Commission, printed or typed facsimiles, or computer printed facsimiles, 
provided the documents filed have identical formats to the forms prescribed 
in the Commission's regulations and meet existing Securities Exchange Act 
rules as to such matters as clarity and size (Securities Exchange Act Rule 
12b-12).

SPECIAL INSTRUCTIONS FOR COMPLYING WITH SCHEDULE 13D

Under Sections 13(d) and 23 of the Securities Exchange Act of 1934 and the
rules and regulations thereunder, the Commission is authorized to solicit
the information required to be supplied by this schedule by certain security
holders of certain issuers.

Disclosure of the information specified in this schedule is mandatory, except
for Social Security or I.R.S. identification numbers, disclosure of which is
voluntary. The information will be used for the primary purpose of determining
and disclosing the holdings of certain beneficial owners  of certain equity
securities. This statement will be made a matter of public record. Therefore,
any information given will be available for inspection by any member of
the public.

Because of the public nature of the information, the Commission can utilize 
it for a variety of purposes, including referral to other governmental 
authorities or securities self-regulatory organizations for investigatory 
purposes or in connection with litigation involving the federal securities 
laws or other civil, criminal or regulatory statements or provisions. Social 
Security or I.R.S. identification numbers, if furnished, will assist the 
Commission in identifying security holders and, therefore in promptly 
processing statements of beneficial ownership of securities.

Failure to disclose the information requested by this schedule, except for
Social Security or I.R.S. identification numbers may result in civil or
criminal action against the persons involved for violation of the federal
securities laws and rules promulgated thereunder.

    of the items is to be omitted. The answers to the items shall be so

    information is required. A copy of any information or a copy of the 
    pertinent pages of a document containing such information which is 
    incorporated by reference shall be submitted with this statement as an

         reason to believe such information is not current) beneficially owned

         to direct the receipt of dividends from, or the proceeds from the
         sale of, such securities, a statement to that effect should be included
         in response to this item and, if such interest relates to more than

         INSTRUCTION. For computations regarding securities which represent a
         right to acquire an underlying security, see Rule 13d-3(d)(1) and the
         note thereto.

persons and any person with respect to any securities of the issuer, 
including but not limited to transfer or voting of any of the securities, 
finder's fees, joint ventures, loan or option arrangements, put or calls, 
guarantees of profits, division of profits or loss, or the giving or 
withholding of proxies, naming the persons with whom such contracts, 
arrangements, understandings or relationships have been entered into. Include 
such information for any of the securities that are pledged or otherwise 
subject to a contingency the occurrence of which would give another person 
voting power or investment power over such securities except that disclosure 
of standard default and similar provisions contained in loan agreements need 
not be included.

ITEM 7.  MATERIAL TO BE FILED AS EXHIBITS

Adjustment, "Attrition" shall not include (1) revenue declines resulting from 
lowering the rates offered to pre-Closing ACI customers, or (2) the deflection 
of revenue associated with pre-Closing ACI customers due to transferring or 
converting them to PAC or Parent products or pricing.

     2.3  EFFECT ON OUTSTANDING SHARES.  By virtue of the Merger, 
automatically and without any action on the part of the Shareholder, all of 
the shares of capital stock of ACI, issued and outstanding at the Effective 
Time, shall become and be converted into the Merger Consideration, which 
shall consist of the assumption of the ACI Note Payable (as defined below in 
Subsection (a), shares of Parent Common Stock, and a promissory note issued 
by PAC to Shareholder and guaranteed by Parent, in the following amounts:

          (A)  assumption of ACI's promissory note payable (the "ACI Note 
Payable") to the Shareholder, a copy of which is attached hereto as EXHIBIT 
A, in the outstanding principal amount of $4,000,000, which $4,000,000 ACI 
Promissory Note will be paid in good funds to be transferred by wire transfer 
or by certified or cashier's check on the Closing Date to Shareholder;

          (B)  $10,500,000 in shares (2,800,000 shares) of voting common 
stock of Parent based on a value of $3.75 per share (the "Shares"). The 
Shares will be issued to the Shareholder on the Closing Date and shall not be 
registered under federal or state securities laws. The Shareholder may, by 
providing prior written notice to Parent, require the Parent to register, up 
to 50 percent of the total number of Shares (the "Registrable Shares") 
(including any additional shares of the Parent that may be issued to 
Shareholder with respect to a stock-split or stock dividend transaction) that 
are not held in escrow under the Escrow Agreement attached hereto as EXHIBIT 
B, under federal securities laws on or after one year after the Closing Date 
or as reasonably practicable thereafter. If the Shareholder proposes to offer 
the Registrable Shares in an underwritten offering, Parent must consent to 
the use of the underwriter chosen by Shareholder. Such consent shall not be 
unreasonably withheld. Notwithstanding the above, the Parent, in its sole 
discretion, may register all or part of the Shares under federal securities 
laws without receiving written notice or consent from the Shareholder. In the 
event that Parent registers Shares without receiving written notice from the 
Shareholder, the Shareholder may only require the Parent to register that 
additional number of Shares, if any, up to the number of Registrable Shares 
before or on or about one year after the Closing Date or as reasonably 
practicable thereafter. In the event that Parent registers part or all of the 
Shares, Parent may also register additional shares of its securities at the 
same time as the registration of the Shares and in the same Registration 
Statement filed with the U.S. Securities and Exchange Commission. The Shares 
are "RESTRICTED SECURITIES" as that term is defined under federal securities 
laws, and, therefore their transferability is limited. Parent shall pay for 
the costs of registering the Shares (including any additional shares of the 
Parent that may be issued to Shareholder with respect to a stock-split or 
stock dividend transaction); Shareholder or its assigns shall pay for all 
brokerage fees and costs and its or their own attorneys' fees, if any. Prior 
to effectiveness of any Registration Statement Shareholder shall agree to 
indemnify Parent against certain liabilities, including liabilities under the 
Securities Act of 1933, as amended. Notwithstanding the foregoing, the 
registration rights granted to Shareholder shall terminate if the 
restrictive holding period imposed by Rule 144 under the Securities Act of 
1933, as amended, is shortened to a period of one year or less by an amendment 
to Rule 144 prior to the exercise of any registration rights hereunder. In 
such event, PAC and Parent will use their best efforts to remove the then 
stock legend relating to the Shares. The remaining fifty percent (50%) of the 
Shares will be held in escrow under the Escrow Agreement; and


                                       10
<PAGE>

          (C)  the Merger Consideration minus $14,500,000 shall be 
represented by the promissory note of PAC (the "NOTE") to be issued and 
delivered by PAC to the Shareholder as set forth below, in the form of the 
attached EXHIBIT C. At the Closing, PAC will issue and deliver to Shareholder 
a promissory note (the "TEMPORARY NOTE"), in the form of the attached EXHIBIT 
D, in the principal amount of $2,400,000. The Temporary Note shall be 
nonnegotiable and nontransferable. On April 1, 1996, Shareholder will return 
the Temporary Note to PAC for cancellation and PAC will simultaneously issue 
and deliver the Note to Shareholder. The Note and the Temporary Note each 
will be guaranteed by the Parent, in the form of guaranty attached as EXHIBIT 
E, and accrue interest at the rate of nine percent per annum. Accrued 
interest under the Note shall accrue from the Closing Date. The Note and the 
Temporary Note are subject to a right of setoff as further described in 
Section 12.4 of this Plan. Principal and interest shall be payable as 
provided for in the Note.

3.   ADDITIONAL DEPOSITS BY THE SHAREHOLDER TO THE ESCROW.

     To the extent that Shareholder receives any refunds relating to (i) U.S. 
West "CAB" charges and (ii) Colorado state tax claims, then Shareholder shall 
deposit as an addition to the Escrow Deposit, the cash amount equal to any 
such refunds less and after the Shareholder has recovered (1) her accountable 
out-of-pocket expenses incurred in obtaining such refunds and (2) $60,000.

4.   REPRESENTATIONS AND WARRANTIES OF ACI AND THE SHAREHOLDER.

     Except to the extent disclosed in the Disclosure Schedule, ACI and the 
Shareholder, jointly and severally, make the following representations and 
warranties to PAC and Parent, each of which is true and correct on the date 
hereof, shall remain true and correct up to the Effective Time, and as to

<PAGE>

          (D)  Except as set forth in Part 4.16 of the Disclosure Schedule,

          (E)  ACI is not engaged, and has never been engaged, in any unfair 
labor practice of any nature. There has never been any slowdown, work 
stoppage, labor dispute or union organizing activity, or any similar activity 
or dispute, affecting ACI or any of its employees. There is not now pending, 
and no Person has threatened to commence, any such slowdown, work stoppage, 
labor dispute or union organizing activity or any similar activity or 
dispute. To the knowledge of ACI and Shareholder, no event has occurred, and 
no condition or circumstance exists, that directly or indirectly will give 
rise to or provide a basis for the commencement of any such slowdown, work 
stoppage, labor dispute or union organizing activity or any similar activity 
or dispute.

    4.17  EMPLOYEE BENEFIT PLANS. Set forth in Part 4.17 of the Disclosure 
Schedule is a list of all employment agreements, severance agreements or 
arrangements, parachute agreements, employee or director bonus, deferred

purchase, employee stock ownership, stock appreciation rights, savings, 
consulting, stock appreciation rights, group insurance, fringe benefit, and 
other employee benefit, incentive, and welfare plans, policies, contracts and 
arrangements, formal or informal, write or oral, and all trust agreements 
related thereto, now in effect and relating to any present or former 
directors, officers, or employees of ACI, whether or not described in Section 
3(3) of the Employee Retirement Income Security Act of 1974, as amended 
("ERISA") (collectively, the "EMPLOYEE PLANS"). All of the Employee Plans 
have been maintained, operated, and administered in substantial compliance 
with their terms, and ACI and all of the Employee Plans currently comply, and 
have at all relevant times complied, in all material respects with applicable 
provisions of ERISA, the Code, securities laws and other applicable laws. 
With respect to each Employee Plan (whether currently in effect or which has 
been terminated) which is a pension plan (as defined in Section 3(2) of 
ERISA) (a "PENSION PLAN"), each such Pension Plan (and any trust relating 
thereto) intended to be a qualified plan under Section 401(a) of the Code has 
been determined by the IRS to be so qualified. Neither ACI nor any ERISA 
Affiliate has in the past or now maintains, sponsors or contributes to any 
plan subject to Title II of ERISA or Section 412 of the Code (including any 
multi-employer pension plans defined in Section 3(37) of ERISA), and ACI has 
never incurred any liability to any person, entity or agency by reason of the 
withdrawal from or termination of any plan. No "PROHIBITED TRANSACTION" (as 
defined in Section 406 of ERISA or Section 4975 of the Code) with respect to 
any "EMPLOYEE BENEFIT PLAN" (as defined under Section 3(3) of ERISA, each 
such plan an "ERISA PLAN") has occurred which is likely to result in any 
penalties or taxes under Section 502(i) of ERISA or Section 4975 of the Code. 
All reporting any disclosure requirements of ERISA and the Code have been 
complied with in all material respects with respect to each of the ERISA 
Plans and each other Employee Plan. ACI has not contributed to any 
"MULTIEMPLOYER PLAN," as defined in Section 3(37) of ERISA, nor any plan that 
is subject to Title IV of ERISA, on or after September 26, 1980. Except as 
set forth in Part 4.17 of the Disclosure


                                       23

contract relating to such Employee Plan, (iv) the most recent summary plan 
description for such Employee Plan, if it is subject to Title I of ERISA, and

directly or indirectly give rise to, or result in ACI becoming subject to, 
any such liability.

          (C)  Except as set forth in Part 4.18 of the Disclosure Schedule,

Registration Statement(s) become(s) effective, contain any untrue statement 
of a material fact or omit to state any material fact required to be stated

in connection with the Registration

Statement(s), will comply as to form and substance in all material respects 
with the provisions of applicable law.

    4.29  SECURITIES LAWS COMPLIANCE.

          (A)  INVESTMENT INTENT. Shareholder is acquiring the Shares, the 
Note and the Temporary Note (collectively, the "Securities") solely for her 
own account for investment and not with a view to or for sale in connection 
with any distribution of the Securities or any portion thereof and not with 
any present intention of selling, offering to sell or otherwise disposing of 
or distributing the Securities or any portion thereof in any transaction 
other than a transaction exempt from registration under the 1933 Act.

          (B)  RESIDENCE.  Shareholder's principal residence is located at 
1559 Genesee Vista, Golden, Colorado 80401.

          (C)  INFORMATION CONCERNING THE PARENT AND PAC.  Shareholder has 
heretofore received all information regarding Parent and PAC and their plans, 
operations and financial condition as the Shareholder has deemed necessary 
and appropriate to enable her to evaluate the financial risk inherent in 
making an investment in the Securities, and Shareholder has received 
satisfactory and complete information concerning the business and financial 
condition of Parent and PAC in response to all inquiries in respect thereof.

          (D)  ECONOMIC RISK.  Shareholder realizes that the Securities will 
be a highly speculative investment and involve a high degree of risk, and 
Shareholder is able, without impairing the Shareholder's financial condition, 
to hold the Securities for an indefinite period of time and to suffer a 
complete loss of her investment.

          (E)  RESTRICTED SECURITIES.  Shareholder understands that the 
Securities are being offered and sold without registration under the 1933 
Act, and without qualification under the securities or blue sky laws of any 
state, pursuant to exemptions from registration and qualifications relating 
to transactions not involving a public offering or solicitation. These 
exemptions only exempt the issuance of the Securities to Shareholder and not 
any sale or other disposition of the Securities or any interest therein by 
Shareholder. Accordingly, there can be no assurance that Shareholder will be 
able to sell or transfer any of the Securities or any interest therein, and 
Shareholder agrees not to make any such sales or dispositions unless the 
Securities are so registered or qualified or other conditions (which may 
never be met) are met. The Shareholder is acquiring the Securities solely for 
her own account for the purpose of investment and not with a view to or for 
sale in connection with any distribution thereof.

          (F)  RESTRICTIVE LEGEND.  (i) Shareholder acknowledges that the 
certificate or certificates evidencing the Shares, the Temporary Note and the 
Note will bear a legend to the following effect or in some variable form in 
Parent and PAC's discretion:

    12.1 SURVIVAL OF REPRESENTATIONS AND COVENANTS.

         (A) All of the representations, warranties, covenants and 
obligations of the Shareholder contained in this Plan shall survive the

             (1) any breach of any representation or warranty made by ACI or

Effective Time, (B) the presence of any hazardous material at any site owned, 
leased, occupied or controlled by ACI on or at any time prior to the

Section 12).

         (B) BY PAC AND PARENT. PAC and Parent shall hold harmless and 
indemnify Shareholder from and against, and shall compensate and reimburse 
Shareholder for, any Damages which are directly or indirectly suffered or 
incurred by Shareholder or to which Shareholder may otherwise become subject 
at any time (regardless of whether or not such Damages relate to any 
third-party claim) and which arise directly or indirectly from or as a direct 
or indirect result of, or are directly or indirectly connected with:

             (1) any breach of any representation or warranty made by PAC or

<PAGE>

ACI or Shareholder;

             (4) any liability to which Shareholder may become subject and 
that arises directly or indirectly from or relates directly or indirectly to 
any product manufactured or sold, or any service performed, by or on behalf 
of PAC and Parent after the Effective Time; or

             (5) any Proceeding relating directly or indirectly to any 
breach, alleged breach, liability or matter of the type referred to in clause 
"(1)," "(2)," "(3)," or "(4)" above (including any Proceeding commenced by 
Shareholder for the purpose of enforcing any of her rights under this 
Section 12).

    12.3 THRESHOLD AND SOURCE OF INDEMNITY. Shareholder shall not be required 
to make any indemnification payment pursuant to Section 12.2(a) for any 
breach of any of its or ACI's representations, warranties, covenants and 
other agreements until such time as the total amount of all Damages 
(including the Damages arising from such breach and all other Damages arising 
from any other breaches of any representations, warranties, covenants and 
other agreements) that have been directly or indirectly suffered or incurred 
by any one or more of the Indemnitees, or to which any one or more of the 
Indemnitees has or have otherwise become subject, exceeds $50,000 in the 
aggregate. At such time as the total amount of such Damages exceeds $50,000 
in the aggregate, the Indemnitees shall be entitled to be indemnified against 
the full amount of such Damages (and not merely the portion of such Damages 
exceeding $50,000).

    Neither PAC or Parent shall be required to make any indemnification 
payment pursuant to Section 12.2(b) for any breach of any of its 
representations, warranties, covenants and other agreements until such time 
as the total amount of all Damages (including the Damages arising from such 
breach and all other Damages arising from any other breaches of any 
representations, warranties, covenants and other agreements) that have been 
directly or indirectly suffered or incurred by the Shareholder, or to which 
the Shareholder has otherwise become subject, exceeds $50,000 in the 
aggregate. At such time as the total amount of such Damages exceeds $50,000 
in the aggregate, the Shareholder shall be entitled to be indemnified 
against the full amount of such Damages (and not merely the portion of such 
Damages exceeding $50,000). Nothing in this Section 12.3 shall be 
construed to extend the time period specified in Section 12.1.

    12.4 SETOFF. In addition to any rights of setoff or other rights that PAC 
and/or Parent or any of the other Indemnitees may have at common law, by 
statute or otherwise, PAC and/or Parent shall have the right to set off any 
amount that may be owed to any Indemnitee under this Section 12 (including 
but not limited to the breach by ACI or Shareholder of a representation, 
warranty, covenant or other agreement) against any amount otherwise payable 
by PAC or Parent under the Note, the Temporary Note and the Escrow Agreement 
otherwise, or by any other Indemnitee, to the Shareholder. For example, in 
the event that PAC is owed $75,000 by Shareholder pursuant to this Section 
12, PAC shall have the right, in its sole discretion, to offset any payment 
under the Note or the Escrow Agreement by a corresponding $75,000.


                                     44

<PAGE>

     PAC and Parent shall have the option of the setoff of all or any part of 
any Damages they may suffer by notifying the Shareholder in writing that PAC 
and/or Parent is electing to recover Shares from the Escrow Deposit 
established by the Escrow Agreement between PAC and Shareholder, subject to 
the terms and conditions of said Escrow Agreement and this Plan. For the 
purposes of setoff against the Escrow Deposit, (i) in the event that the ask 
price is lower than $3.75 per Share as of the date that PAC and/or PAC 
exercise(s) its right of setoff herein, then PAC and Parent must setoff 
against the Shares, and (ii) in the event that the bid price is at least 
$3.75 per Share as of the date that PAC and/or PAC exercises its right of 
setoff herein, then PAC and Parent may setoff against the Shares, the 
Temporary Note, or the Note, in its sole discretion. Nothing in this Section 
12.4 shall be construed to extend the time period specified in Section 12.1.

     12.5  NONEXCLUSIVITY OF INDEMNIFICATION AND SETOFF REMEDIES. The 
indemnification and setoff remedies and other remedies provided in this 
Section 12 shall not be deemed to be exclusive. Accordingly, the exercise by 
any Person of any of its rights under this Section 12 shall not be deemed to 
be an election of remedies and shall not be deemed to prejudice, or to 
constitute or operate as a waiver of, any other right or remedy that such 
Person may be entitled to exercise (whether under this Plan, under any other 
contract, under any statute, or other Legal Requirement, at common law, in 
equity or otherwise). Nothing in this Section 12.5 shall be construed to 
extend the time period specified in Section 12.1.

     12.6  EXERCISE OF REMEDIES BY INDEMNITEES OTHER THAN PAC AND PARENT. No 
Indemnitee (other than PAC, Parent or any successor thereto or assign 
thereof) shall be permitted to assert any indemnification claim or exercise 
any other remedy under this Plan unless PAC and Parent (or any successor 
thereto or assign thereof) shall have consented to the assertion of such 
indemnification claim or the exercise of such other remedy.

13.  MISCELLANEOUS PROVISIONS.

     13.1  FURTHER ASSURANCES. Each party hereto shall execute and/or cause 
to be delivered to each other party hereto such instruments and other 
documents, and shall take such other actions, as such other party may 
reasonably request (prior to, at, or after the Closing) for the purpose of 
carrying out or evidencing any of the Transactions.

     13.2  FEES AND EXPENSES. 

           (A)  Subject to the indemnification provisions set forth in 
Section 12, Shareholder shall bear and pay all fees, costs and expenses 
(including all legal fees and expenses payable to counsel for ACI and 
Shareholder) that have been incurred or that are in the future incurred by, 
on behalf of or for the benefit of ACI or Shareholder in connection with:

required to be made or given by the parties in connection with any of the 
Transactions, and obtaining any Consent required to be obtained in connection 
with any of the Transactions; and

                (4)  the consummation and performance of the Transactions.

           (B)  Subject to the indemnification provisions of Section 12, PAC 
and Parent shall bear and pay all fees, costs and expenses (including all 
legal fees and expenses payable to Freeborn & Peters) that have been incurred 
or that are in the future incurred by or on behalf of PAC and Parent in

     13.3  ATTORNEYS' FEES.  If any legal action or other legal proceeding 
(including arbitration) relating to any of the Transactional Agreements or 
the enforcement of any provision of any of the Transactional Agreements is 
brought against any party hereto, including, but not limited to any claim under 
which indemnity is sought pursuant to Section 12 hereunder, the prevailing 
party shall be entitled to recover reasonable attorneys' fees, costs and 
disbursements (in addition to any other relief to which the prevailing party 
may be entitled).

        AMONG PHOENIX NETWORK ACQUISITION CORP., PHOENIX NETWORK, INC.,
              AUTOMATED COMMUNICATIONS, INC. AND JUDY VAN ESSEN

                                   GUARANTY

     WHEREAS, Phoenix Network Acquisition Corp., a Delaware corporation (the 
"Debtor"), has obtained a loan from Judy Van Essen (hereinafter called the 
"Creditor") pursuant to that certain Agreement and Plan of Merger dated 
January 16, 1996; and

     WHEREAS, the undersigned is the sole shareholder of the Debtor so that 
the undersigned has a substantial economic interest in Debtor and expects to 
derive substantial benefits from any loans and financial accommodations 
resulting in the creation of indebtedness of Debtor to Creditor; and

     WHEREAS, the Creditor has refused to provide such loans or other 
financial accommodations to Debtor unless and until the undersigned agrees to 
guaranty the obligations of Debtor to the Creditor;

     NOW, THEREFORE in consideration of the above premises and to induce the 
Creditor to hereafter extend credit to the Debtor, and for other 
consideration, the undersigned does hereby unconditionally guarantee the 
prompt payment to the Creditor when due, whether at the maturity date or 
dates specified therein or theretofore upon acceleration of maturity pursuant 
to the provisions thereof, Debtor's now existing or hereafter arising 
obligations under (a) that certain Promissory Note of even date herewith (the 
"Note") by and among the Debtor and the Creditor; and (b) any renewals or 
extensions of or amendments to the foregoing (all of such obligations and 
liabilities being hereinafter called "Guaranteed Obligations") together 
with any and all expenses of and incidental to collection, including 
reasonable attorneys' fees.

     This guaranty is an absolute and completed one and shall be a continuing 
one and no notice of the Guaranteed Obligations or of any renewal or 
extension thereof need be given to the undersigned, who hereby expressly 
waives presentment, demand notice of nonpayment, protest, and notice of 
protest on any and all forms of such Guaranteed Obligations and also notice 
of acceptance of this guaranty except as required below.

     The undersigned hereby:

          (a)     Consents that the Creditor may without affecting or impairing
the liability of the undersigned hereunder take any one or more of the 
following actions:

                  (i)    Waive or delay the exercise of any of its rights or 
          remedies against the Debtor or any other person or entity;

<PAGE>

                  (ii)   Release the Debtor or any other person or entity;

                  (iii)  Renew or extend the terms of the Guaranteed 
          Obligations; or

                  (iv)   Apply payments by the Debtor, the undersigned, or any 
          other person or entity, to the Guaranteed Obligations in such amounts
          and proportions as the Creditor may deem advisable whether the same 
          shall be due or not.

          (b)     Further consents that upon the receipt by Guarantor of any 
notice required to be sent to Debtor, the liability of the undersigned 
hereunder shall not be affected or impaired:

                  (i)    by any failure, neglect or omission on the part of 
          the Creditor to realize upon any Guaranteed Obligations;

                  (ii)   by the taking by the Creditor of any other guaranty 
          or guaranties to secure the Guaranteed Obligations;

                  (iii)  by the taking by the Creditor of collateral or 
          security of any kind; or

                  (iv)   by any act or failure to act whatsoever (except 
          payment), which but for this provision might or could in law or in 
          equity act to release or reduce the undersigned's liabilities 
          hereunder.

     The undersigned acknowledges that this guaranty is in effect and binding 
as to the undersigned without reference to whether it is signed by any other 
person or persons, or any other entity or entities, and agrees that 
possession of this instrument of guaranty by the Creditor shall be conclusive 
evidence of due delivery hereof by the undersigned. The undersigned 
acknowledges that the undersigned's liability upon this guaranty shall be 
terminated only upon payment of the Guaranteed Obligations, regardless of the 
source of payment, provided however, that the undersigned's liability hereon 
shall continue as to: (a) Guaranteed Obligations then existing in the event 
of a partial payment; and (b) as to any Guaranteed Obligations collected by 
Creditor from the Debtor which are required to be disgorged by a court or 
other tribunal having jurisdiction over such matters. As to any portion of 
the Guaranteed Obligations the undersigned will not, without the Creditor's 
consent, collect from Debtor the claim, if any (by subrogation or otherwise), 
acquired through payment by any of the undersigned of a part of the 
Guaranteed Obligations regardless of whether or not such Guaranteed 
Obligations have been paid and satisfied in full and any commitments therefor 
have been terminated.

     This guaranty shall be construed and interpreted in accordance with and 
governed by the laws of the State of Colorado in which state it shall be 
performed by the undersigned. The undersigned consents to the jurisdiction of 
the state and federal courts located in the state of Colorado, waives any 
arguments that venue in such forums is not convenient and agrees that any 
litigation initiated by the undersigned will be venued in such forum.


                                       2
<PAGE>

     The provisions of this guaranty are severable, and in any action or 
proceeding involving any State corporate law, or any State or Federal 
bankruptcy, insolvency, reorganization or other law affecting the rights of 
creditors generally, if the obligations of the undersigned hereunder would 
otherwise be held or determined to be void, invalid or unenforceable on 
account of the amount of the liability of the undersigned under this 
guaranty, then notwithstanding any other provision of this guaranty to the 
contrary, the amount of such liability shall, without any further action by 
the undersigned, the Creditor or any other person, be automatically limited 
and reduced to the highest amount which is valid and enforceable as 
determined in such action or proceeding.

     This guaranty shall be binding upon the undersigned and upon the legal 
representatives, successors and assigns of the undersigned, and shall inure 
to the benefit of the Creditor and its successors and assigns. In case the 
Creditor at any time transfers to any transferee any of the Guaranteed 
Obligations then existing, the right to require the undersigned to pay the 
same may be assigned to the transferee by, but will not vest in such 
transferee in the absence of, an express written assignment thereof made by 
the Creditor either at or after the time of the transfer of any of the 
Guaranteed Obligations. No such assignment will impair the Creditor's right 
hereunder to look to the undersigned for payment of untransferred Guaranteed 
Obligations to the extent that they may not be required to answer to the 
assignee up to the full limit of their liability hereunder.

     Dated as of this ____ day of January, 1996.

                           PHOENIX NETWORK, INC.

                            AFFILIATE AGREEMENT


Gentlemen:

     The undersigned, a holder of shares of Common Stock ("Company Common
Stock") of Automated Communications, Inc., a Colorado corporation (the 
"Company"), is entitled to receive in connection with the merger (the 
"Merger") of the Company with and into Phoenix Network Acquisition Corp.
("PAC"), a Delaware corporation, with PAC being the surviving corporation
in such Merger, securities of Phoenix Network, Inc. ("Parent Securities").
The undersigned acknowledges that the undersigned may be deemed an "affiliate"
of Parent within the meaning of Rule 144 ("Rule 144") promulgated under the
Securities Act of 1933, as amended (the "Act"), although nothing contained
herein should be construed as an admission of such fact.

     If in fact, the undersigned were an affiliate under the Act, the
undersigned's ability to sell, assign or transfer the Parent Securities
received by it in exchange for any shares of Company Common Stock pursuant
to the Merger may be restricted unless such transaction is registered under
the Act or an exemption from such registration is available. The undersigned
has obtained advice of counsel as to the nature and conditions of such
exemptions, including information with respect to the applicability to the
sale of such securities of Rules 144 promulgated under the Act.

     The undersigned hereby represents and warrants to and covenants with
Parent and PAC that she will not sell, assign, or transfer any of the
Parent Securities received by her in exchange for shares of Company Common
Stock pursuant to the Merger except (i) pursuant to an effective Registration
Statement under the Act, or (ii) in a transaction which, in the opinion of
independent counsel reasonably satisfactory to Parent or as described in a
"no-action" or interpretive letter from the Staff of the Securities and
Exchange Commission, is not required to be registered under the Act.

     In the event of a sale or other disposition of Parent Securities 
pursuant to Rule 144, the undersigned will supply Parent with evidence
of compliance with such Rule, by delivery of a letter in the form of
EXHIBIT A hereto and the opinion of counsel referred to above. The 
undersigned understands that Parent may instruct its transfer agent to
withhold the transfer of any Parent Securities disposed of by the 
undersigned but that upon receipt of such letter and opinion the transfer
agent shall effectuate the transfer of the Parent Securities sold as
indicated in the letter.


                                     1

<PAGE>

     The undersigned acknowledges and agrees that appropriate legends will
be placed on certificates representing Parent Securities received by the
undersigned in the Merger or held by a transferee thereof, which legends
will be removed by delivery of substitute certificates upon receipt of
an opinion in form and substance reasonably satisfactory to Parent to
the effect that such legends are no longer required for the purpose of the
Act.

     The undersigned acknowledges that she has carefully read this letter
and understands the requirements hereof and the limitations imposed upon
the distribution, sale, transfer or other disposition of shares of Parent
Securities.

Dated: January 16, 1996

     As an inducement to the above individual to deliver this letter, Parent
agrees that for so long as and to the extent necessary to permit such 
individual to sell the Parent Securities pursuant to Rule 144 under the Act,
Parent shall use its reasonable best efforts to file, on a timely basis, all
reports and data required to be filed by it with the SEC pursuant to 
Section 13 of the Securities Exchange Act of 1934. Upon written request
addressed to Phoenix Network, Inc., 550 California Street, 11th Floor, San
Francisco, California 94104, attention Mr. Jeffrey Bailey, Parent agrees to
promptly advise the above individual that Parent has complied with such
reporting requirements.

Attention: Corporate Secretary

     On ___________________, I sold the securities ("Parent Securities") of
Phoenix Network, Inc., ("Parent") described below in the space provided for
that purpose. The Parent Securities were received by me in connection with
the merger of Automated Communications, Inc. with and into Phoenix Network

the Securities and Exchange Commission, the Parent Securities sold by me
were within the prescribed limitations set forth in paragraph (e) of
Rule 144 promulgated under the Securities Act of 1933, as amended (the
"Act").

     I hereby represent that the Parent Securities were sold in "brokers'
transactions" within the meaning of Section 4(4) of the Act or in
transactions directly with a "market maker" as that term is defined in
Section 3(a)(38) of the Securities Exchange Act of 1934, as amended. I
further represent that I have not solicited or arranged for the solicitation
of order to buy the Parent Securities, and that I have not made any
payments in connection with the offer or sale of the Parent Securities to
any person other than to the broker who executed the order in respect of
such sale.

     THIS NONCOMPETITION AGREEMENT (the "Agreement") is made this 16th day of

                                   RECITALS

     WHEREAS, the Shareholder is a director, chief executive officer and sole 
shareholder of the Corporation, which is engaged in the telecommunications 
business, including but not limited to the reselling of long distance 
telephone service and operating DMS 250 Switches in _____________ (the

1996 whereby the Corporation will merge with and into PAC (the "Merger").

     WHEREAS, PAC and Parent would not have entered into the Plan and agreed 
to the Merger unless the Shareholder agreed to enter into this Agreement.

     WHEREAS, PAC and Parent recognize that the Shareholder has unique 
knowledge and experience in the Business, and of the territory of the 
Corporation, and that the Shareholder has personal knowledge of the market 
for the Business in the State of ______________. Accordingly, the Shareholder 
has agreed to enter into this Agreement which prohibits the Shareholder from 
competing with PAC and Parent on the terms and subject to the conditions 
hereinafter set forth.

     NOW, THEREFORE, in consideration of the Recitals hereto, which the 
parties agree constitute a substantive part of this Agreement, the mutual 
covenants, promises and agreements herein contained, and other good and 
valuable consideration, the receipt and sufficiency of which is hereby 
acknowledged, the parties hereto do hereby covenant, promise and agree as 
follows:

     1.  COVENANT AGAINST COMPETITION.

         1.1  The parties hereto acknowledge and agree that PAC and Parent 
would not have agreed to the Merger and to enter into the Plan unless the 
Shareholder agreed to enter into this Agreement. Accordingly, the Shareholder 
agrees that for a period of five (5) years from the date of this Agreement, 
the Shareholder shall not do any of the following:


                                       1

<PAGE>


              (a)  Within the State of _______________, solicit for 
employment or independent contract work or employ to or for the benefit or 
account of any person or entity other than PAC or Parent any employee of PAC 
and Parent, and any employee of Corporation as of January 1, 1996, nor shall 
they urge, directly or indirectly, any customers of the Corporation, PAC and 
Parent to discontinue, in whole or in part, business with the Corporation or 
not to do business with PAC and Parent; provided, however that (i) 
Shareholder may solicit for employment the following employees of the 
Corporation, but only if such ensuing employment does not relate in any 
manner to the Business, or the business of PAC and Parent: Lori Emory, Laura 
Lanphier, Judy Todd, Jennifer Burger and Norma Nielsen; and (ii) from January 
16, 1998 through January 16, 2001, Shareholder may solicit any employee or 
former employee of the Corporation, but only if such ensuing employment does 
not relate in any manner to the Business, or the business of PAC and Parent;

              (b)  Excluding the Shares issued pursuant to the Plan, have any 
financial interest in any corporation or other business organization that is 
engaged in any parts of the Business anywhere that the Corporation, PAC and 
Parent, or any of their affiliates, previously conducted or has present plans 
to conduct business in the future. Notwithstanding the above sentence, 
nothing shall prevent Shareholder from owning any outstanding securities of 
any corporation actively traded on a recognized securities exchange or the 
Nasdaq Stock Market; PROVIDED, HOWEVER, that such ownership does not 
constitute "control" of such corporation pursuant to Rule 405 of the 
Securities Act of 1933, as amended; and

              (c)  Within the State of _____________, directly or indirectly 
(whether as principal, agent, independent contractor, employee or otherwise) 
own, manage, operate or control or otherwise carry on, or be engaged in, any 
business engaged in any of the Business that the Corporation, PAC or Parent 
conducts now or in the future. Notwithstanding this Section 1, Shareholder 
may work as a distributor or other agent for PAC and/or Parent in connection 
with the business opportunity (involving private labeling and provision of 
long distance and, potentially, local telephone service, by cable companies 
to their subscriber base) presented to the Corporation by Treasury and 
Accounting Technologies, Inc. and Bruce Heverly, provided all such sales in 
that capacity are made solely to PAC and Parent and any of their affiliates; 
and Shareholder may also, whether individually or through an affiliation with 
a business entity, sell or resell Internet access.

         1.2  The parties hereto agree all such covenants and agreements 
herein are separate and distinct and that to the extent that any provision or 
portion of Section 1.1 of this Agreement shall be held, found or deemed to be 
unreasonable, unlawful or unenforceable by a court of competent jurisdiction, 
then any such provision or portion thereof shall be deemed to be modified to 
the extent necessary in order that any such provision or portion thereof 
shall be legally enforceable to the fullest extent permitted by applicable 
law; and the parties hereto do further agree that any court of competent 
jurisdiction shall, and the parties hereto do hereby expressly authorize, 
request and empower any court of competent jurisdiction to, enforce any such 
provision or portion thereof or to modify any such provision or portion 
thereof in order that any such


                                       2

<PAGE>

provision or portion thereof shall be enforced by such court to the fullest 
extent permitted by applicable law.

     2.  CONSIDERATION.  In consideration of the covenants and agreements of 
the Shareholder under this Agreement, PAC or Parent shall pay an aggregate 
amount of $25,000 to the Shareholder on the date hereof; additional 
consideration for such covenants and agreements is the consideration paid 
under the Plan.

     3.  CONFIDENTIAL INFORMATION.  The Shareholder recognizes that due to 
the nature of the transactions contemplated under the Plan, the Shareholder 
may have access to confidential and proprietary information (as described 
below) relating to the business and operations of the Corporation, PAC and 
Parent and their respective assets, liabilities, contracts and business. The 
Shareholder acknowledges that such information has been and will continue to 
be of critical importance to the business of PAC and Parent and that 
disclosure of it to or its use by others could cause substantial loss to PAC 
or Parent. Accordingly, the Shareholder agrees as follows:

         3.1  The Shareholder will keep confidential any and all "trade 
secrets and confidential and proprietary information" of the Corporation, 
PAC and Parent and their respective assets, liabilities, prospects, condition 
and business which are now known or which hereafter may become known to the 
Shareholder and shall not at any time directly or indirectly disclose any 
such information to any person or entity, or use the same in any way other 
than in connection with the business of the Corporation, PAC and Parent 
during and at all times after the term hereof; provided, however, that the 
Shareholder may disclose "trade secrets and confidential and proprietary 
information" to the extent (i) reasonably necessary to prosecute or defend 
pending and future claims by and/or against the Shareholder and the 
Corporation, which claims arise out of or relate to actions or omissions by 
the Shareholder and/or the Corporation before the date hereof; and (2) 
required by a court, tribunal or other administrative body.

         3.2  For purposes of this Agreement, "trade secrets and confidential 
and proprietary information" shall include but not be limited to information, 
whether written or otherwise, unique to the Corporation, PAC and Parent and 
their respective assets and business which has a significant business purpose 
and is not known or generally available from sources outside PAC, Parent, the 
Shareholder or the Corporation or typical of industry practice, including, 
but not limited to, information with respect to costs, pricing, present and

      EXHIBIT I TO AGREEMENT AND PLAN OF MERGER DATED JANUARY 16, 1996
       AMONG PHOENIX NETWORK ACQUISITION CORP., PHOENIX NETWORK, INC.,
            AUTOMATED COMMUNICATIONS, INC. AND JUDY VAN ESSEN

                INDEMNIFICATION AND HOLD HARMLESS AGREEMENT

     This Indemnification and Hold Harmless Agreement (the "Agreement")
is entered into this 16th day of January, 1996, between and among PHOENIX
NETWORK ACQUISITION CORP., a Delaware corporation ("PAC"), PHOENIX NETWORK,
INC., a Delaware corporation ("Parent"), AUTOMATED COMMUNICATIONS, INC., a
Colorado corporation ("ACI"), and JUDY VAN ESSEN, individually 
("Shareholder"), the sole shareholder of ACI prior to the merger of ACI
with and into PAC.

                                   RECITALS

     A.  PAC, Parent, ACI and Shareholder have entered into an Agreement
and Plan of Merger ("Plan") whereby ACI will merge with and into PAC 
effective as of the Effective Time as defined in the Plan.

     B.  ACI is involved in certain pending or threatened lawsuits, 
including but not limited to those listed on Exhibit A attached hereto as
well as claims that may arise in the future relating solely to actions
which took place on or prior to the date of this Agreement (collectively,
the "Legal Claims").

     C.  PAC, Parent, ACI and Shareholder desire that PAC, ACI and Parent
shall be indemnified to the extent that any of them are required to 
participate in, defend, or in any way be responsible or liable for any
costs, fees, judgments, settlements, payments or other obligations relating
in any manner to the Legal Claims.

     E.  PAC's and Parent's willingness to enter into the Plan is expressly
conditioned upon entering into this separate Indemnification and Hold
Harmless Agreement with Shareholder, and PAC would not agreed to have ACI
merged with and into PAC without Shareholder's agreement to fully indemnify
PAC, Parent and ACI pursuant to the terms and conditions of this Agreement.

     F.  Any capitalized term not defined herein shall have the meaning set
forth in the Plan.

    NOW, THEREFORE, in consideration of the premises, promises, and the 
mutual covenants and agreements set forth in this Agreement, the sufficiency
of which are hereby acknowledged, the Parties agree as follows:

<PAGE>

                                   AGREEMENT

     1.  (a)  Shareholder hereby acknowledges and agrees that she shall be
solely responsible for the defense (and related fees and costs) relating to
or arising from any and all of the Legal Claims. Shareholder shall have
the right and obligation to direct and control the defense, prosecution
and settlement of all of the Legal Claims.

         (b)  Shareholder hereby acknowledges and agrees that she shall be
solely responsible for the defense (and related fees and costs) relating to
or arising from the revocation or nonallowance of ACI's election to be
taxed under Subchapter "S" of the Internal Revenue Code of 1986, as amended
(a "Tax Claim") for the three (3) tax years ending prior to the Effective
Date. Shareholder shall have the right and obligation to direct and control
the defense, prosecution and settlement of a Tax Claim.

         (c)  Prior to the engagement of legal counsel to defend any Tax
Claim or Legal Claims pursuant to this paragraph 1, Shareholder shall provide
PAC and Parent with a letter signed by such legal counsel substantially
in the form attached hereto as Exhibit 1.

     2.  Shareholder further agrees to fully indemnify, defend and hold
harmless PAC, Parent and ACI against any and all claims, judgments, payments,
expenses, liabilities and actual damages, including reasonable attorneys'
fees, that PAC, Parent and/or ACI shall incur or suffer which arise, result
from or relate in any way to a Tax Claim or Legal Claims (collectively, a
"Claim"). Shareholder's indemnity obligation shall not extend to or cover
any claims asserted against PAC or Parent that are not Legal Claims or Tax
Claims.

     3.  Promptly after the receipt by PAC, Parent or ACI of written notice
of any Claim or threat of Claim, PAC, Parent or ACI shall give written
notice of such Claim to Shareholder. This notice shall include, at a 
minimum, all details of the claim then known to PAC and/or Parent and all
documents which PAC and/or Parent received. Thereafter, Shareholder, upon
request of PAC, Parent or ACI, shall assume the defense thereof, including
retaining counsel mutually agreed upon with PAC to represent PAC, Parent
and ACI, and shall pay the fees and expenses of any such counsel related
to the Claim or proceeding as well as any outside professional fees and
expenses incurred by PAC, Parent and ACI. Concerning any such Claim or 
proceeding, PAC, Parent and ACI shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense
of them, unless (i) PAC, Parent or ACI and Shareholder shall have mutually
agreed to retention of such counsel; (ii) the Claim relates to the
Omitted Claims; or (ii) the named parties to such proceeding (including
impleaded parties) include PAC, Parent or ACI and Shareholder, and 
representation of more than one of such parties by the same counsel would
be inappropriate due to actual or potential differing interests between
them.


                                     -2-

<PAGE>

     4.  Notwithstanding anything to the contrary hereinabove, Shareholder's
obligation to indemnify pursuant to paragraphs 1 through 3 above shall
terminate under the following conditions:

         (a)  With regard to Claims relating to any of the matters disclosed
on Exhibit A attached hereto, Shareholder's obligations shall continue
indefinitely;

         (b)  With regard to Claims which arise in connection with the
collection of ACI's accounts receivable by PAC or Parent, written notice
of such a Claim must have been provided to Shareholder on or before
eighteen (18) months following the date of this Agreement or Shareholder's
obligations to indemnify shall terminate with regard to those Claims for
which notice has not been provided within such period;

         (c)  With regard to Tax Claims, written notice of a Tax Claim must
have been provided to Shareholder on or before thirty-six (36) months
following the date Shareholder files ACI's final tax return or Shareholder's
obligations to indemnify shall terminate with regard to a Tax Claim for
which notice has not been provided within such period;

         (d)  With regard to all other Claims not otherwise described in
subparagraphs (a) through (c) above, written notice of a such Claim must
have been provide to Shareholder on or before thirty-six (36) months
following the date of this Agreement or Shareholder's obligations to
indemnify shall terminate with regard to any such Claims for which notice
has not been provided within such period.

         (e)  To the extent any notice of a Claim is given pursuant to 
any of subparagraphs 4(b), (c) or (d) above, and such Claim is disputed
by Shareholder, PAC or Parent shall initiate formal arbitration to resolve
such dispute with respect to such Claim within ninety (90) days of the
date of such notice of Claim or Shareholder's indemnification obligations
as to such Claim shall terminate and be null and void.

     5.  In addition to any rights of setoff or other rights that PAC
and/or Parent may have at common law, by statute or otherwise, PAC and/or
Parent shall have the right to set off any amount that may be owed to
either PAC or Parent pursuant to this Agreement against any amount
otherwise payable by PAC or Parent under the Note, the Temporary Note or
the Escrow Agreement (as these terms are defined in the Plan) to the
Shareholder.

     PAC and Parent shall also have the option of the setoff of all or any
part of any damages they may suffer by notifying the Shareholder in 
writing that PAC and/or Parent is electing to recover Shares from the
Escrow Deposit established by the Escrow Agreement (as those terms are
defined in the Plan) between PAC and Shareholder, subject to the terms
and conditions of said Escrow Agreement, the Plan and this Agreement.
For the purposes of setoff against the Escrow Deposit, the Temporary
Note, or the Note, the priorities set forth in the Plan shall control.
